SVG Emoji Favicon and Title Tutorial

The recent SVG Network Clock Start Local Time Favicon Tutorial talked about …

  • SVG data basis …
  • emoji data content …
  • favicon web browser tab icon … SVG type not accepted by all browsers and platforms …
  • dynamism … and today we start with another offshoot of thought regarding this, as well as …
  • document.title also showing in the web browser tab icon … universally accepted …

… ideas we wanted to get into by writing a pretty simple generic PHP helper emojiicon.php, we got a great heads up from regarding its logic, thanks, to dynamically create favicon.svg, currently looking like …

… in our nominated folder (so, so far not catering for a lot of online traffic … we’ll see) …

SVG Network Clock Start Local Time Favicon Tutorial

Today we’re revisiting the SVG Network Clock we last talked about with SVG Network Clock Minimize Tutorial. Why?

Well, we were re-researching the topic of Favicon (those images on the tabs of your web browser tabs) that we talked about when we presented Gimp Favicon via Logo Primer Tutorial, but we realize now, things have moved on with the web browsers supporting SVG svg+xml “favicons” so much better these days, that we’d better “get with the plan”, so to speak (though it might be better if I give that a rest for a minute).

…
…
…
…

Okay, minutes up!

With increased usage of SVG svg+xml text element solutions for things around here lately, we wondered whether there was a dynamic way to start using these SVG favicons, in some way. Then we thought of our SVG Clock work. At first we thought a favicon that is a relevant timestamp, but realized the impost on the web server is too big for that, and so we set out to present a local start time of the SVG Clock for a user of this web application. The SVG favicon basis is so simple …


<?xml version="1.0" standalone="no"?>
<!DOCTYPE svg PUBLIC "-//W3C//DTD SVG 1.1//EN"
"http://www.w3.org/Graphics/SVG/1.1/DTD/svg11.dtd">
<svg width="32" height="32" version="1.1" xmlns="http://www.w3.org/2000/svg" style="background-color:white; letter-spacing:-1px; transform:scale(1,1.6);>
<text x="0%" y="65%" stroke="black" stroke-width="1" fill="red" font-size="16px">11:54</text>
</svg>

Stick the SVG file in Document Root folder, and replace “11:54” with the relevant timestamp and we’re away, right? Yes, sort of, but there is the little matter of the relevant favicon link statement existing as a non-dynamic call to that SVG in the head section of the webpage.

Bit onerous, huh? But, what did work for us was to have a static starting wrong favicon SVG link (in head) statement that now goes in the parental svg_clock.html SVG Network Clock …

<head>


<link id='mylink' rel='icon' href='/faviJUNKcon.svg' sizes='any' type='image/svg+xml'>

SVG Network Clock Minimize Tutorial

Today’s blog posting’s underlying SVG Network Clock web application (we last talked about with Colour Wheel Size and Spoke Colour Tutorial’>Colour Wheel Size and Spoke Colour Tutorial) shares a couple of commonalities with yesterday’s MAMP Timekeeping Web Application Visibility Tutorial, those being …

… those Page Visibility API ideas you might equate to “minimize” concepts, that originated when GUIs were left to deal with how to present the representation of an application when it is no longer front and center in front of the user as an opened up window. We’d “minimize” back down to the desktop icon or toolbar view of the application. Web browsers can have tabs for this equivalent purpose, and we can improve the usefulness of a web application that can still be useful when “minimized” out of the top viewing tab. Date and time themed web applications can be your more obvious candidate for usefulness here. Just present a form of “digital clock readout” and your web applications like our SVG Network Clock can still be a source of information, even when “minimized”. We think that is an improvement?!

As you might have noticed with the last application of Page Visibility API “smarts”, this API is not hard to use, but for the first time we can remember, making changes just to the changed HTML supervisor svg_clock.html SVG Network Clock supervisor HTML and Javascript, and only changed to see in a new external Javascript svg_clock.js helper, we saved coding time by being able to …

  • scrutinize the DOM …
  • within an “object” HTML element’s …
  • SVG … featuring in some new Javascript with its own Page Visibility API reference …

    function huhcont() {
    var dtidea='';
    var dotwis=['Sunday','Monday','Tuesday','Wednesday','Thursday','Friday','Saturday'];
    if (document.title != origdtis || ishd == ishd.toUpperCase()) { setTimeout(huhcont, 1000); }
    ishd == ishd.toLowerCase();
    if (document.getElementById('myclock') && ('' + document.visibilityState) == 'hidden') {
    if (document.getElementById('myclock').contentDocument.documentElement.outerHTML.indexOf(' id="sclock"') != -1) {
    console.log('predtidea');
    dtidea=document.getElementById('myclock').contentDocument.documentElement.outerHTML.split(' id="sclock"')[1].split('<')[0].split('>')[1].trim();
    console.log('dtidea=' + dtidea + ' ... ' + document.URL);
    if (dtidea != '') {
    document.title=dtidea;
    } else if (document.URL.indexOf('timezone=') != -1) {
    document.title=('' + new Date().toLocaleString("en-US", {timeZone: (location.search.split('timezone=')[1] ? decodeURIComponent(location.search.split('timezone=')[1].split('&')[0]) : "")}) + ' ' + (location.search.split('timezone=')[1] ? decodeURIComponent(location.search.split('timezone=')[1].split('&')[0]) : "") + ' ' + (location.search.split('emflag=')[1] ? decodeURIComponent(location.search.split('emflag=')[1].split('&')[0]) : ""));

Your words, helped out by some computer derived detail data, can help personalize your work using the Quarter Hour Timekeeping web application of yesterday’s MAMP Timekeeping Web Application Web Share API Tutorial which, at least with the Safari browser (and a whole lot of other macOS conditions), now integrates with the Web Share API to attach images to prepared emails with a “body blurb”. It is that prepared “body blurb” we are trying to refine, today, should the user attach any of those Timekeeper screenshot files created via macOS screencapture command.

This is because these screenshot file names, by our convention, are of the format …

… within the macOS MAMP‘s $_SERVER[‘DOCUMENT_ROOT’] folder (though the path to the file is unavailable to File API File object programmers).

The recent MAMP Timekeeping Web Application PHP Notifications Tutorial‘s Timekeeping via Screenshots changed HTML and Javascript quarter_hour_timer.html (we ask you to download to MAMP‘s $_SERVER[‘DOCUMENT_ROOT’] “HTMLCSS” subfolder) Web Application supervisor is another very suitable candidate for interfacing to our recent Webpage Audio Commentary functionality. Both …

… share an …

  • underlying macOS or Mac OS X operating system dependence …
  • underlying local web server such as MAMP …
  • downloaded into that local web server Document Root folder PHP code

… set of interest points for full and useful functionality, because of two macOS or Mac OS X commands, respectively …

We add the changed macos_say_record.js external Javascript call into the supervisory HTML and Javascript <head></head> webpage section via …


<script type='text/javascript' src='//www.rjmprogramming.com.au/macos_say_record.js?ongoing=1721156687576' defer></script>

… sitting up at the Document Root of your public domain, that “?ongoing=” based $_GET[‘ongoing’] argument deliberate, effectively asking the code to look out for “on the fly” HTML elements created within an execution run of the webpage.

We add some “smarts” to those global data attribute usage we talked about at Webpage macOS Say Audio Commentary Access Count Tutorial, allowing some “date extraction” templating via the supervisory HTML and Javascript array declaration as per …


<script type='text/javascript'>
var commentary_array=['textarea', 'You can enter comments about this screenshot here %value%outerHTML%@yyyymmdd%hhmm%.', 'img', 'Timekeeper screenshot here %id%@yyyymmdd%hhmm%.'];
</script>

… where the first field describes an HTML element attribute to first look at, the optional second is a stand by attribute, followed by “date extraction” fields to match with numerical data found so as to substitute the blue parts with a “date and timestamp” string.

MAMP Timekeeping Web Application PHP Notifications Tutorial

Today we’re revisiting the macOS (or Mac OS X) or Windows timekeeping web application of 2016’s Mac OS MAMP Timekeeping Web Application PHP Calendar Aesthetics Tutorial. Why? Well, given our recent work with Notifications API based web applications you can read about at Notification API Hidden Popup Tutorial, the timekeeping one is a great candidate for functionality improvement here, it being a web application that …

  • can work behind the scenes …
  • not necessarily frontmost … but benefitting from any …
  • notification reminders separate from web activities and webpage focus issues can help tell the user when they might want to turn back attention to the timekeeping screenshot recording

This needs PHP to work and it needs real access via PHP exec function to underlying operating system commands. When this happens, we still try to offer a public RJM Programming interface but this interface is far less useful if you have not downloaded to your local Apache/PHP/MySql local web server (such as a MAMP one) as per …

  1. the changed quarter_hour_timer.php (we ask you to download to MAMP‘s $_SERVER[‘DOCUMENT_ROOT’] “HTMLCSS” subfolder) Timekeeping Web Application suited to macOS (or Mac OS X) “screencapture” command line usage
  2. the unchanged (from tutorial below, supervisory HTML and Javascript) quarter_hour_timer.html (we ask you to download to MAMP‘s $_SERVER[‘DOCUMENT_ROOT’] “HTMLCSS” subfolder) Timekeeping Web Application
  3. the “how we got there” PHP notifications_ideas.php (we ask you to download to MAMP‘s $_SERVER[‘DOCUMENT_ROOT’] subfolder) Notification API functionality PHP web application

… in what we like to call an “Intranet feeling” scenario.

Up at the public RJM Programming domain, as far as the Notification API functionality supervisor webpage goes, the changed HTML and Javascript notifications_ideas.html Notification API functionality HTML and Javascript web application is worth trying.

  • make some styling calendar tweaks …

    a.adate { border:2px solid transparent; background-color:lightgreen; border-radius:50px; }
    </style>
  • settle for mobile platforms never being able to screenshot, on this round of looking, and redirecting to the “Monthly Chronicler” web application (of (the unchanged) monthly_chronicler.html we ask you to download to MAMP‘s $_SERVER[‘DOCUMENT_ROOT’] “HTMLCSS” subfolder) …

    <script>
    if (navigator.userAgent.match(/Android|BlackBerry|iPhone|iPod|iPad|Opera Mini|IEMobile/i)) {

    }
    </script>

    … dumbing down, but working more reliably, using “Javascript writes Javascript” methodology

… which you may glean has a Windows “fallback” position (with that “copy” codeline). Why? Well, we found a .Net framework “exe creation via bat” using ScreenCapture.bat (thanks to this useful link) created black screen shots. Probably a privilege thing or PHP exec thing, but we’ve opted for the workaround, which is just “Windows talk” …

  • write Windows batch scapcontinuous.bat as a continuous fifteen minute user of the .Net Framework (ScreenCapture.exe) derived from above
  • set up a task via “Task Schedular” (please ignore the warts ‘n all “garden path” schtask ideas in the video below) that has an action “C:\MAMP\htdocs\scapcontinuous.bat” and starts when the Windows user logs in and takes (successful) screen shots at 14 and 29 and 44 and 59 minutes (in the hour) times

Mac OS MAMP Timekeeping Web Application PHP Calendar iCal Integration Tutorial

Yesterday’s Mac OS MAMP Timekeeping Web Application PHP Calendar Contenteditable Tutorial‘s “Calendar Past” improvements don’t have to be the end of the story regarding “calendar timings”. There is an Apple iCal standard interfacing format that can drive calendar integrations with many well known online Calendar applications.

You may recall us talking about this with Calendar Location Services Integration Tutorial and we tweak the changed ics_attachment.php (which we’d ask you to download to MAMP‘s $_SERVER[‘DOCUMENT_ROOT’] “PHP” subfolder) and its standalone ical creator to better integrate with the changed quarter_hour_timer.html (we ask you to download to MAMP‘s $_SERVER[‘DOCUMENT_ROOT’] “HTMLCSS” subfolder) Timekeeping Web Application suited to macOS (or Mac OS X) “screencapture” command line usage.

This bit of functionality works (interfacing) both with MAMP and with the public RJM Programming domain incarnation of the Timekeeping web application, so that could be interesting. It can interface via …

… modes of use. In action, should you create an iCal file this way, the web application will download the resultant .ics file into your Downloads folder and to interface into your default online Calendar application double click that Downloads folder file to complete the Calendar integration …

We’ve spoken quite a bit in the past about the joys of involving the “contenteditable=true” attribute for HTML elements that have an “innerHTML” (ie. they have a formalized end tag arrangement eg. div, span, p, td, th etcetera) and with today’s work which extends that started with yesterday’s Mac OS MAMP Timekeeping Web Application PHP Calendar Past Tutorial it is the turn of a set of “p” elements it helps out today.

The scenario is that yesterday’s work did not allow for “orphaned screenshots” of the past be allowed to be brought back into play to “annotate them” and in so doing “give them a home”. This led us to …

  • allow for a new “Infill Earlier Days All Screenshots” button augment yesterday‘s “Infill Earlier Days Just Annotated Screenshots” button …
  • the pressing of that new “Infill Earlier Days All Screenshots” button causes all screenshot 15 minute entries relevant to the current year be displayed in the calendar … but then it occurred to us users might want to “annotate them” … but how? …
  • in the PHP we introduced code …
    <?php

Mac OS MAMP Timekeeping Web Application PHP Calendar Tutorial

Okay then, yesterday’s Mac OS MAMP Timekeeping Web Application PHP Image Metadata Tutorial “image metadata smarts” puts us in a position to get onto the “bells and whistles” side of our Timekeeping (macOS and Mac OS X only at this stage) web application. We channel the calendar display talents of Monthly Chronicler LocalStorage Tutorial in thought and act (its web application is opened in an iframe … hence our need to ask you to download monthly_chronicler.html to MAMP‘s $_SERVER[‘DOCUMENT_ROOT’] “HTMLCSS” subfolder) to offer a new (“reveal”) piece of details/summary hosted “Yearly Report Calendar” functionality.

Mac OS MAMP Timekeeping Web Application PHP Image Metadata Tutorial

In our opinion, what would make the day before yesterday’s Mac OS MAMP Timekeeping Web Application PHP Intranet Tutorial “Timekeeping Web Application” cooler would be to add to the intelligence of the screen capture images, ahead of other data related improvements to come.

We’ve spoken in the past about Exif in that respect but PHP has Iptc image metadata functions we can call on …

  • iptcembed to embed new metadata into an existant image from those associated “caption” textarea elements we offer
  • iptcparse to extract old metadata from an existant image into those associated “caption” textarea elements we offer

This metadata can be like a database source we use moving forward on this project, meaning the one image data entity can suffice for both visual and textual usage purposes.

And so our changed quarter_hour_timer.html Timekeeping Web Application suited to macOS (or Mac OS X) “screencapture” command line usage, is helped out by a much more usefully changed quarter_hour_timer.php PHP …

Mac OS X MAMP Timekeeping Web Application Email Tutorial

The practicalities of yesterday’s (Mac OS X MAMP Timekeeping Web Application Primer Tutorial) timekeeping Mac OS X Web Application, left as they are, would leave you with a somewhat useful web application whose use is only for the here and now, but what if you want it to be more accountable? Well, that is when we, here, at RJM Programming, like to use that tried and trusted email form of communication.

Today’s email methods spurn the use of server-side intervention, at least for now. So what is available to us as tools, if we don’t include Ajax nor jQuery in that list? Well, we have, to our minds …

  • mailto links (get us to the email client) +
  • the body section of that email can have a clipboard image pasted into it, for which we can utilize HTML5 canvas element’s toDataURL() method, teamed up with a window.open popup window of the toDataURL image data, which can be selected and copied, optionally, by the user themselves, should they wish this to make their email more self explanatory

We last discussed this thinking with Canvas Annotation Email Attachment Clipboard Tutorial.

We rely on the crontab functionality, being as there is no server-side help, to create the image file, whose contents eventually go to make up the contents that can be selected and copied and pasted by the user into the body section of the email (and sent off to whosoever they feel like sending it too, as you have the full power of the email client available to you with the interaction you have with an actual email client program).

Here is the HTML and Javascript quarter_hour_timer.html which changed to cater for today’s email functionality in this way, and, as per the Stop Press from yesterday, we’ll also have a live run link here today.

Mac OS X MAMP Timekeeping Web Application Primer Tutorial

Mac OS X MAMP Timekeeping Web Application Primer Tutorial

Sometimes when you program, especially for administrative type functionality, there are useful programs to write, that are able to become web applications, but in a limited set of platforms. So it is today with our timekeeping web application that relies on …

  • Mac OS X operating system +
  • Existance of [/usr/sbin/]screencapture +
  • crontab active and editable via crontab -e +
  • One of …
    1. MAMP installed to, in our case, /Applications/MAMP/htdocs/ (as is mentioned in the relevant crontab background task that snapshots the user’s screen every quarter hour) that maps to the MAMP web application URL http://localhost:8888/ … or …
    2. crontab directory mention that corresponds to a URL call of our web application like for our Google Chrome example (where the directory below, used, could be a place of your choosing (that matches what is in your crontab task entry)) …

      file:///Applications/MAMP/htdocs/quarter_hour_timer.html?localplace=

      … or just, via the web browser’s File -> Open File menu …

      file:///Applications/MAMP/htdocs/quarter_hour_timer.html

… pretty restrictive, huh? … but pretty useful for our quarter hour timekeeping purposes today.

We want to have a web application that is running at the user’s discretion, and when first fired up, looks for outputs from crontab tasks above …


0,15,30,45 * * * * /usr/sbin/screencapture -Cd -tjpg /Applications/MAMP/htdocs/screen-`date +"\%Y\%m\%d-\%H\%M"`.jpg

… for the current day in question and if existant show …

  1. a date and time stamp +
  2. the snapshot of what you were doing at the quarter hour, that is clickable to make bigger for more in depth viewing +
  3. an HTML textarea element in which you can optionally type in more specifics about that quarter hour

So, as much as we like to think of Mac OS X Terminal application’s BSD (a unix derivative) operating system, as being a lot like Linux, there are some commands and usage that …

  • adds Mac OS X specific command line functionality to a Linux or unix base set of functionality, like for today’s screencapture command … and we’ve included another such example, below, with the command say featuring in Mac OS X Text to English Speech Primer Tutorial as shown below
  • changes switches on Linux or unix commands
  • won’t have some Linux or unix commands that other platforms do

In the great tradition of behoving … we behove … we behove thee quarter_hour_timer.html if you like, my liege. On this occasion you’ll have gleaned that there is no live run link, because the RJM Programming web server is not Mac OS X … so command line screencapture has no meaning for a CentOS web server’s operating system command line. You’ll see in the code that rather than use “Client Pre-emptive Iframe” concepts to check for existence of crontab screen capture images, we, instead use the onerror event for HTML img elements to check for non-existance.

Stop Press

Just noticed that, perhaps, after all, a live run from the RJM Programming website can make sense if you have a Mac OS X laptop, for instance, that is running that suggested crontab entry as explained in tutorial above. That type of live run managed to latch on to our local crontab screencaptures on my MacBook Pro.

Mac OS X Text to English Speech Primer Tutorial

Mac OS X Text to English Speech Primer Tutorial

We’ve got a few new ideas today …

  1. Text to English Speech via Mac OS X’s command line say command used by PHP via exec to make say.php (which is useful as a download to a Mac OS X laptop using MAMP) which, today, does not have a live run because the web server of domain rjmprogramming.com.au is a CentOS Linux server … Linux equivalent of Mac OS X’s say? … read here
  2. Trying to present this brought up the usual movie production problem with iMovie overlaying the audio on top of the video (though you may want to try, and you could start reading with this link) versus QuickTime Player talent to catch both audio and video tracks (and that we ended up using), but not of the “screen goings on”, alas versus MPlayer OSX Extended which can play separately but not two tracks on top and doesn’t do any reconstituting … so …
  3. Improved on our inhouse Video/Audio synchronizing efforts by allowing audio_video.html supervisor (changed in this way) be able to be called to press one of its preconceived synchronization buttons onload which we do with (the newly added) Macbeth Act 1 Scene 1 … in a small celebration of the Bard … who, am thinking (in that Falstaff way), would have got a huge chuckle out of “anonymous” instead of “anon” during the Three Witches scene … we had to do something to say Happy Birthday

Along the way we tried filming the MacBook Pro with the iPad to a YouTube …

… but weren’t happy with the audio quality, alas (too/two).

Floor Wall and Roof Framing Members Song Lyrics Tutorial

What do Carpentry and Octopus Anatomy have in common? Anyone, anyone?

Yes, Ringo?

Yes, perhaps they both live in a Yellow Submarine? Or the Octopus’s Garden needs a new lattice? But, no, we invite other takers … Anyone, anyone?

Yes, Paul … you have a vision coming on … ?

2026 … yes …
World Cup … yes …
Winner will be … yes …

Okay, that’s it! No more! Not even “finding an arrowed diagram for Octopus Anatomy that functioned like the one we used for our Carpentry web application” … though that’s remarkably prescient. No, it’s that … yes, Katherine and Richard … you’re right there … Songs, Lyrics, Music!

To get from today’s octopus.html‘s changed code then we …

  1. started with the Carpentry HTML and Javascript code as a basis …
  2. surfing the net found interesting octopus image via this Google image search finding this applicable image (from “Methodologies for studying finfish and shellfish biology” (ISBN: 978-93-82263-03-6) by Dineshbabu Ap), thanks, that we scanned and copied (and which we later change) into an image file on this MacBook Pro that was uploaded to …
  3. visited mobilefish to create the new image (img element) and associated map element …
  4. replaced the old Carpentry img and map with the new Octopus ones, pointing the img element src property at the correct image … that image now …
  5. opened octopus image in Gimp and Gaussian Blurred out the octopus labels via …
    • Tools -> Selection Tools -> Rectangle Select
    • Filters -> Blur -> Gaussian Blur… Horizontal: 14.0px Vertical: 14.0px
  6. (unit) tested code, and realized we’d forgotten to …
  7. within the new octopus img and map code replace all ” title=” for ” data-title=” (to hide answers from the user) and ” href=” for ” data-href=” to stop navigation resetting the score

… to arrive at where we are at with today’s live run. We hope you try it, and learn a bit about Octopus Anatomy should that be your thing!

Floor Wall and Roof Framing Members Primer Tutorial

We all learn differently, but personally, I find it easier to learn things of a certain ilk and things that are new to me, when the study material is augmented by pictures in the form of a diagram or photograph or video, perhaps. I know very little about carpentry, and get lost in conversations talking about “joists” and “bearers”, so, today, we’ve purloined the great mobilefish image map (of HTML area elements) creator website and this very useful webpage (the source of the great diagram … thanks) to piece together today’s “click and learn” web application.

We use some overlay techniques with today’s game where the user tries to identify diagram labels Gaussian Blurred out (via GIMP) while a non-Gaussian-Blurred-out image is used (in an overlayed way) as the background (via background-position definitions) for HTML divs …

  • position:absolute; left:[derivedViaMinAreaXCoords]px; top:[derivedViaMinAreaYCoords]px; width:[derivedViaMaxMinDiffAreaXCoords]px; height:[derivedViaMaxMinDiffAreaYCoords]px;
  • z-index:9;
  • background:URL([non-Gaussian-Blurred-out_image]); background-position:-[derivedViaMinAreaXCoords]px -[derivedViaMinAreaYCoords]px;
  • data attributes (eg. data-title) hide answers from the user to avoid making it all too easy, and internalize navigation (eg. data-href)

… revealed as above when the user gives up (via a space answer) or answers some words correctly in the Javascript prompt window used to prompt the user for “carpentry” terminology word matches, the score incrementing for each correct word match.

Now hope you don’t go around “nogging” in public with your newfound knowledge trying out today’s live run test of your carpentry and building knowledge. It is based on HTML and CSS and Javascript you could call floor_wall_roof_framing_members.html and download, as you wish.

  2. surfing the net found interesting octopus image via this Google image search finding this applicable image (from “Methodologies for studying finfish and shellfish biology” (ISBN: 978-93-82263-03-6) by Dineshbabu Ap), thanks, that we scanned and copied (and which we later change) into an image file on this MacBook Pro that was uploaded to …
  3. visited mobilefish to create the new image (img element) and associated map element …
  4. replaced the old Carpentry img and map with the new Octopus ones, pointing the img element src property at the correct image … that image now …
  5. opened octopus image in Gimp and Gaussian Blurred out the octopus labels via …
    • Tools -> Selection Tools -> Rectangle Select
    • Filters -> Blur -> Gaussian Blur… Horizontal: 14.0px Vertical: 14.0px
  6. (unit) tested code, and realized we’d forgotten to …
  7. within the new octopus img and map code replace all ” title=” for ” data-title=” (to hide answers from the user) and ” href=” for ” data-href=” to stop navigation resetting the score

… to arrive at where we are at with today’s live run. We hope you try it, and learn a bit about Octopus Anatomy should that be your thing!

We all learn differently, but personally, I find it easier to learn things of a certain ilk and things that are new to me, when the study material is augmented by pictures in the form of a diagram or photograph or video, perhaps. I know very little about carpentry, and get lost in conversations talking about “joists” and “bearers”, so, today, we’ve purloined the great mobilefish image map (of HTML area elements) creator website and this very useful webpage (the source of the great diagram … thanks) to piece together today’s “click and learn” web application.

We use some overlay techniques with today’s game where the user tries to identify diagram labels Gaussian Blurred out (via GIMP) while a non-Gaussian-Blurred-out image is used (in an overlayed way) as the background (via background-position definitions) for HTML divs …

  • position:absolute; left:[derivedViaMinAreaXCoords]px; top:[derivedViaMinAreaYCoords]px; width:[derivedViaMaxMinDiffAreaXCoords]px; height:[derivedViaMaxMinDiffAreaYCoords]px;
  • z-index:9;
  • background:URL([non-Gaussian-Blurred-out_image]); background-position:-[derivedViaMinAreaXCoords]px -[derivedViaMinAreaYCoords]px;
  • data attributes (eg. data-title) hide answers from the user to avoid making it all too easy, and internalize navigation (eg. data-href)

… revealed as above when the user gives up (via a space answer) or answers some words correctly in the Javascript prompt window used to prompt the user for “carpentry” terminology word matches, the score incrementing for each correct word match.

Now hope you don’t go around “nogging” in public with your newfound knowledge trying out today’s live run test of your carpentry and building knowledge. It is based on HTML and CSS and Javascript you could call floor_wall_roof_framing_members.html and download, as you wish.

    • With this in mind, we spent some time, onto yesterday’s Knockout Dice Game Checkbox Tutorial progress for that Knockout Dice Game making it …

    Knockout 👊 Dice 🎲🎲 Game

    … even there in the web browser tab’s title.

    For the first time we can remember we needed to get ahead of the curve picking a suitable CSS font-family property for all text with this work because we found that some of the dice guise emojis were really new and not found in all the font families out there, so …


    <style>
    * { font-family: 'DejaVu Sans'; }

    .xone:before { font-family: 'DejaVu Sans'; content: '\002680'; color:blue; }
    .xtwo:before { font-family: 'DejaVu Sans'; content: '\002681'; color:blue; }
    .xthree:before { font-family: 'DejaVu Sans'; content: '\002682'; color:blue; }
    .xfour:before { font-family: 'DejaVu Sans'; content: '\002683'; color:blue; }
    .xfive:before { font-family: 'DejaVu Sans'; content: '\002684'; color:blue; }
    .xsix:before { font-family: 'DejaVu Sans'; content: '\002685'; color:blue; }
    .zone:after { font-family: 'DejaVu Sans'; content: '\002680'; color:blue; }
    .ztwo:after { font-family: 'DejaVu Sans'; content: '\002681'; color:blue; }
    .zthree:after { font-family: 'DejaVu Sans'; content: '\002682'; color:blue; }
    .zfour:after { font-family: 'DejaVu Sans'; content: '\002683'; color:blue; }
    .zfive:after { font-family: 'DejaVu Sans'; content: '\002684'; color:blue; }
    .zsix:after { font-family: 'DejaVu Sans'; content: '\002685'; color:blue; }

    .kout:after { content: '\01f44A'; }

    #snum { background-color: yellow; }

    #header { background-color: #f0f0f0; }

    select { white-space:pre-wrap; border-radius: 6px; }

    button { border-radius: 12px; }

    </style>

    … solved some issues for us, here. And in researching totally CSS ways to style via content, again, we got a leave pass to not look again. CSS (style) and HTML (substance) have been separated by the W3C powers that be, for a reason, and we see that CSS selectors based on “content starts with” will never happen, though you can probably use jQuery library calls to achieve this.

    Okay, with that in mind, we abandoned a CSS only “cute” way to display die values either side of a numerical dice roll total in the header table cell which updates dynamically, instead using this Javascript …


    function diceemojis(totv, secv) {
    var hprefix='', hsuffix='', classbit='';
    var firstv=eval(totv - secv);
    if (1 == 1) {
    var sels=document.getElementsByTagName('select');
    for (var isels=0; isels<sels.length; isels++) {
    if (('' + sels[isels].value.replace(/^0/g,'')) == ('' + totv)) { classbit=' class="kout"'; }
    }
    hprefix=('' + secv).replace(/1/g, '<sup class=xone></sup>').replace(/2/g, '<sup class=xtwo></sup>').replace(/3/g, '<sup class=xthree></sup>').replace(/4/g, '<sup class=xfour></sup>').replace(/5/g, '<sup class=xfive></sup>').replace(/6/g, '<sup class=xsix></sup>')
    hsuffix=('' + firstv).replace(/1/g, '<sub class=zone></sub>').replace(/2/g, '<sub class=ztwo></sub>').replace(/3/g, '<sub class=zthree></sub>').replace(/4/g, '<sub class=zfour></sub>').replace(/5/g, '<sub class=zfive></sub>').replace(/6/g, '<sub class=zsix></sub>')
    return hprefix + '<span' + classbit + ' id="span' + rollno + '">' + totv + '</span>' + hsuffix;
    }
    return (' <span class="' + firstv + ' ' + secv + '">' + totv + '</span>').replace(/\ 1\"/g, ' zone"').replace(/\ 2\"/g, ' ztwo"').replace(/\ 3\"/g, ' zthree"').replace(/\ 4\"/g, ' zfour"').replace(/\ 5\"/g, ' zfive"').replace(/\ 6\"/g, ' zsix"').replace(/\"1\ /g, '"xone ').replace(/\"2\ /g, '"xtwo ').replace(/\"3\ /g, '"xthree ').replace(/\"4\ /g, '"xfour ').replace(/\"5\ /g, '"xfive ').replace(/\"6\ /g, '"xsix ');
    }

    Around here, we’re often moving on in a project via …

    • the changing of hardcodings into “dropdown” select elements (especially within h1 header elements) … but today, to move on, we arrange for …
    • the nested insertion of a checkbox (initially checked) within an h1 header element

    … which for the first time we can remember, we adjust “opacity aesthetics” to add a useful dynamic setting adjustment to the Knockout Dice Game created when we presented Knockout Dice Game Primer Tutorial some time ago now …


    <h1><div id=divword style=display:inline-block;>Knockout</div> Dice Game for <div id='dnum' style='display:inline-block;'><select style='display:inline-block;' onchange='fixinstone(this.value);' id='snum'><option value=2>2</option><option value=3>3</option><option value=4>4</option><option value=5>5</option><option value=6>6</option><option value=7>7</option><option value=8>8</option><option value=9>9</option></select></div> <span id=sgwta style=opacity:1.0;><input onchange="document.getElementById('sgwta').style.opacity='' + eval(1.1 - eval('' + document.getElementById('sgwta').style.opacity));" style=display:inline-block;opacity:1.0; type=checkbox id=gwta checked></input>Winner Take All</span> Players</h1>

    This “Winner Takes All” checkbox controlled mode of use defaults to being set (which is unusual for us, when we add a new form of methodology like this) because we discovered, revisiting this game, that “passivity” was, sort of, being rewarded and so we felt like we needed to add in the idea (and the concept of “No Winner” needed to be added), into the game, where it is really user participation encouraged here, to make the game interesting. Adding to that interest is that in a “Winner Takes All” mode of use, if a player can be the lone player to survive “Knockouts” they score a point for every roll of the two dice to get to this “lone winner” scenario.

    The other issue we noticed were the right hand overflows of our tabulated dropdowns when a lot of players are asked for. We started rearranging content justifications (to now be left justified) so it did not matter if we reduced the (now a better Responsive Design friendly table cell percentage) widths of those dropdowns, so as to fit more fields into the webpage …

    In today’s new (up to two player) Dice Game, we use some of these to represent the numbers from 1 to 6 on the faces of the dice, similar to how you may have seen this happen with dice in various games you play, or hanging from your car’s front visor perhaps?

    … that we were capable of working out ourselves but were reassured by the mathematics of this very useful link, thanks.

    Another game thought unique to how we do things that has been introduced today, is that a user can change the default player names, those being Player1 and Player2 via an HTML div element utilizing the contenteditable=”true” global HTML attribute to make it look readable, but be also “quietly” editable.

    MacBook Air macOS Sequoia Image Playground Tutorial

    MacBook Air macOS Sequoia Image Playground Tutorial

    MacBook Air macOS Sequoia Image Playground Tutorial

    One of the first “out of the box” applications to catch our eye from our Apple macOS install of macOS Sequoia talked about at MacBook Air macOS Sequoia Install Tutorial was …


    Image Playground

    … which we first opened none the wiser to this desktop image creator/editor new to us. We got creating images we’d never have been able to create, content wise, before, in a matter of minutes, and then we asked Google Is macOS Image Playground using AI and it all became clear …

    This is a taste of AI in the image creation workspace.

    So then we wondered if there was a set of rules, yet, about How to Indicate Content is Partially/Wholly AI Generated and realized that there is a way to go, yet, in this space, so that we can inform the reader that image content here contains AI generated image content, so …

    Image based content in this blog posting is AI generated.

    Okay?!

    So, what do we think about macOS Image Playground?

    We’re amazed, no two ways about it … very clever software.

    What else?

    We’ll be avoiding it in favour of pre-AI approaches until the dust settles, we’re thinking, for now, until real creatives’ work can be protected, hopefully getting someway there via some standards.

    What do you think? Is this wildly different to “Photoshopping” images/screenshots (which we are very fond of, here)? Where’s the line?

    It’s been ages since we’ve performed an Apple MacBook macOS upgrade after macOS 11 (ie. Big Sur (and then there was macOS Sonoma version 14 in the mix as we went along)) lifted our head in Calendar Location Services Integration Tutorial.

    But, today we decided to install macOS …

    … Sequoia 15.3.1 after reading “the blurb”. Really, it seems, at this early stage, full of great surprises we’ll get more into over time!

    Previous relevant Calendar Location Services Integration Tutorial is shown below.

    Calendar Location Services Integration Tutorial

    Of all those English question words …

    • why
    • which
    • how
    • what
    • who
    • when
    • where

    … which is more apt as far as software goes? Well, and sorry to our regulars who have heard our theories so often, it goes in order of prominence …

    • where
    • when

    … then the rest … ie. the reverse order of order way above, we reckon.

    And so, being reminded on an upgrade of our macOS version to Big Sur version 11.6 the other day, opening the macOS Calendar desktop application version 11.0 (2811.5.1) (as we did earlier, with a previous version, with Calendar iCal Integration Itinerary Time Tutorial), that locations were honoured with an Apple Maps integration (should you permit Location Services to help you) along with news about Siri integration improving Calendar’s AI credentials, we were pretty much tickled pink to be combining the “when” with the “where” in the one desktop application.

    Maybe you will be too?!

    Previous relevant Calendar Location Services Integration Tutorial is shown below.

    Calendar iCal Integration Itinerary Time Tutorial

    Calendar iCal Integration Itinerary Time Tutorial

    A while back we left off our software integration of Calendar iCal Events into Google Chart Timeline Chart functionality (last visited with Calendar iCal Integration Itinerary Post Tutorial as shown below) with the quote …

    … closing the circle, for now, with our Calendar Event software integrated Timelines.

    … but want to retreat from that “finality”, because it’s been burning away within us as an annoyance, regarding this software integration. We think we can do better (with the integration). And we now think that, doing the research and development on this, that it is technically fairly easy to make that improvement, which goes …

    We want to have the Google Chart Timeline Chart date resolution to match the Calendar iCal Event resolution, which is to the nearest second, rather than to the nearest day, as it used to be for our Google Chart Timeline Charts

    … but we are going to hang back from asking for time hh24:mi:ss entries in the Google Chart Timeline Chart web application itself (when executing as the “parent” web application), because we can accept time data coming in from, say, the Itinerary web application, specifying the date and times to the nearest second (optionally). The reason for this is that to ask for the time everywhere can be offputting when there are so many Timeline scenarios where it is not really the “go” … think, “dates in history” for example.

    What is in the “innards” of the Google Chart Timeline Chart web application controlling this “date” (data) resolution? It is controlled by calls to create Javascript Date objects via Javascript Date object constructor (calls), and up to now, they have been exclusively of the form …


    var date_object = new Date(year, month, date);

    … and this set us to exploring other Javascript Date object constructors, and, as you’d expect … but is a little non-intuitive because of the “Date” object naming … well that’s my excuse, anyway … it allows for (the overload) …


    var date_object = new Date(year, month, date, hour, minute, second);

    But that is not to say that just to see that this (Javascript functionality) is so, doesn’t always make it so (for Google Chart usage). However, it just so happens, it does, in this case, because there are no problems changing these Date constructor calls as far as the software interface to the Google Charts Timeline Chart API is concerned (we unit tested to confirm) … yayyyy!!

    It does mean, though, that the code should handle either type of constructor, and this constructor is significant to our Google Chart select (onclick) event coding, as we examine these constructors from document.head.innerHTML to glean this information.

    We may, next, but not for now, extend the Google Chart Timeline Chart web application to ask for times optionally, perhaps, via the clicking of an HTML input type=checkbox element, but for now we’re happy, because a user can do any of …

    • Google Chart Timeline Chart web application execution where it is the parent web application … date resolution: day
    • Itinerary (web application) that displays into the Google Chart Timeline Chart web application … date resolution: second
    • Date and Time Timeline with Calendar iCal Events (web application) that displays into the Google Chart Timeline Chart web application … date resolution: second

    … and the last two are available as links from the first, so, we figure, the user can end up with what they were after, with all these choices of execution modes.

    And so, what timezones happen here?

    • Google Chart Timeline Chart web applications use your local date (and time)
    • Calendar iCal Event destination use your local date (and time) too … but …
    • iCal interfacing messages most easily use “Z” form, that uses GMT dates (and time)
    • Itinerary (or Date and Time Timeline with Calendar iCal Events) web application allows for times in any timezone you designate

    … and we have to map any non-local timezone usage to local time, especially with the last option above, to avoid confusion, and to make Calendar iCal Event destination application data match the content, and now, resolution, of its Google Chart Timeline Chart counterpart. Annoyance over!

    The results of this work consisted of …

    • no changes to external Javascript you could call gettopost.js … called defer=’defer’ by …

    • our software integration improvement we did that “proof of concept” preparation about yesterday with HTML Div Overlay Jigsaw Talents Primer Tutorial that is actually the means by which we cater for large amounts of “Itinerary” or “Generic Timeline with Dates and Times” data by
      1. establishing a new external Javascript using HTML script property defer=’defer’ loaded after the local Javascript (that contains a “stub” function maybegettopost(instg, showit) { return instg; }) with two major functions … namely …

        • an external Javascript overloading version of function maybegettopost(instg, showit) that checks the length of the proposed get $_GET[] type parameter call (ie. using ? and & on address bar with long URLs), and if too long, convert that $_GET[] type parameter call data into $_POST[] type parameter call (remembering … doh … that the PHP (sorrrryyyy) receiver code should cater for this)
      2. change the “Itinerary” PHP web application code to, from now on, when calling another web application in a (default) $_GET[] type parameter call way, filter that call data through function maybegettopost(instg, showit) … the showit is a boolean that is true if we end up navigating to that call data “URL” (ie. we “show it”)

    Maybe you need to see the software additions and changes to see this for yourself, which consisted of …

    • new external Javascript you could call gettopost.js … called defer=’defer’ by …
    • our PHP “Itinerary”, and now, also, “Generic Timeline with Dates and Times” code you could call itinerary.php which changed a little, and now has the “Itinerary” type of live run and has the “Generic Timeline with Dates and Times (and Calendar Events)” type of live run
    • our PHP above calls the original Google Chart Timeline Chart (with its “onclick” select event functionality) you could call timeline_chart.php which changed a little to recognize Timelines that can Involve Times (and Calendar Events) as well as the usual Dates (and if you want to try its live run … then there it was?!)

    … closing the circle, for now, with our Calendar Event software integrated Timelines. With such software integration, break complex integrations into bits you can unit test, and don’t move on until that unit test works. On the next level of unit testing, make sure you prove that previous unit tests still work.

    • email via PHP mail function

    ? This “Itinerary” concept has a huge amount of synergy with Calendar events, especially as a reminder service to people going on the trip (of the Itinerary) and/or to those affected by their absence, and so we found it a concrete type of web application to “start” out on. Yes, and there’s more! Tomorrow’s blog posting, you’ll have trouble believing, will have a connection, as a “proof of concept”, of where we go next with this project. So, after tomorrow’s explanation, we’ll probably see you back hereabouts in two days.

    But, in the meantime, for starters, try the PHP source code of itinerary.php and its live run to see what we are getting at here. If you try it, you’ll see that the Emoji Overlay sizing is determined on a integration “parent” subject by integration “parent” subject basis.

    … which should come as no surprise of a candidate for Calendar integration.

        • opacity … and though it was optional for today’s work, we also included the third often used “overlay” CSS “player” … namely …
        • z-index

        … and this Javascript function …

        function checkforclass() {
        var buildup="";
        var cfcs=docgetclass('emojioverlay','*');
        for (var ij=0; ij<cfcs.length; ij++) {
        if (cfcs[ij].innerHTML.replace(/&amp;/g,'&').indexOf(';&') != -1) {
        var emjs=cfcs[ij].innerHTML.replace(/&amp;/g,'&').split("&");
        buildup='';
        cfcs[ij].style.opacity=eval(cfcs[ij].style.opacity / eval(-1 + emjs.length));

        cfcs[ij].style.visibility='visible';

        }
        }

      … that is the method used today to display an Emoji Overlay “character” to reflect, for a mobile application WebView scenario, of PHP mail created email usage for the Calendar Event creation functionality

    • Google Chart Annotated Timeline Flash Legacy Tutorial introduced the flexible non-flash and flash toggling functionality of the Google Chart for Timelines PHP web application we wrote called annotatedtimeline_chart.php which changed quite a lot, like “function checkforclass” above, for this Calendar Event creation integration

    Calendar iCal Integration Email Tutorial

    Calendar iCal Integration Email Tutorial

    With yesterday’s Calendar iCal Integration Timezone Tutorial‘s emphasis on timezones, we turn our attention now, thinking of our web application as a “tool” and an integrated software product, to two interrelated issues …

    1. What does the future hold as far as using this Calendar “tool” (web application)? In other words, what software and/or operating system platforms will use it and in what way.
    2. How do we respond with this Calendar “tool” web application, fitting in with the requirements implicit in what the whole gammut of software and/or operating system platforms needing its services will need.

    The most “asking” of “software and/or operating system platforms” that we can think of here is to cater for a mobile application WebView (please read here regarding Android WebView (using Eclipse or Android Studio IDEs) and iOS UIWebView (using Xcode IDE)) using the Calendar “tool” web application. Mobile platform WebViews can be programmed with Back and Forward navigation buttons, but that is not the ideal thing to rely on to get you out of a pickle that your web application may cause a mobile application WebView, if it navigates out to a place where there is no navigable return. The Back and Forward mobile application WebView buttons may work to return from a Calendar Event population event … honestly don’t know … but we’d prefer to cater for a new means by which such an “offshoot” feeling of navigation can be avoided. So in our new incarnation of the Calendar (event) web application we allow any/all of the following three modes of rjmprogramming-event.ics creation …

    1. Create iCal Calendar Entry
    2. Email (only) iCal Calendar Entry
    3. Create and Email iCal Calendar Entry

    … where the second of those above would leave you, within the web application running within a mobile application’s WebView, not moving off the webpage you are on, and thus not falling foul of any “offshoot” navigation weaknesses (to the process).

    This new emailing functionality, again only in serverside PHP (and not in clientside Javascript), is relatively easy to arrange by rearranging many of the PHP header statements and feeding that through to the PHP mail function to shoot off the email, given that the user, ahead of time, has supplied you with that filled in email address, which we also attend to today.

    Our web application has, in two separate areas of the code, made use of an HTML select element’s child option elements’ title properties to contain useful information for the web application’s workings. We’ll show you below some code to access the information stored from such an arrangement …


    <select onchange='document.getElementById("subb").value=this.options[this.selectedIndex].title;' id='emode' name='emode'><option title='Create iCal Calendar Entry' value='Address'>Address</option><option title='Email (only) iCal Calendar Entry' value='To'>Email To (only)</option><option title='Create and Email iCal Calendar Entry' value='AndTo'>Email To (as well)</option></select>

    … and you might wonder about the destination for the HTML option title property storage here? We use it to rename our HTML form’s input type=submit button that fires off the callback message. The “guises” of our one HTML input type=submit thus have a one to one correspondence with the values on that HTML select (dropdown) element, and with that list of “modes of output” we showed above. This is our approach to this today, but there are other approaches to such requirements regarding HTML form element HTML input type=submit element arrangements, and you may prefer to use multiple forms and/or multiple input type=submit buttons as we talk about with the series of blog posts finishing, so far, with HTML Multiple Form Multiple Submit Buttons Primer Tutorial.

    Actually yesterday we prepared for another eventuality down the road of usefulness for this web application, but before we tell you about that, what we’d encourage you to do yourself should you put such a Calendar (event) web application into production is, interface your data flow not with $_POST[] (nor $_GET[] … damn, gave away the secret) but we’d prefer you to have it be that data in and out, as required, is stored in a secure database of some sort, for security purposes. But back to our (not very well kept) secret, yesterday, we prepared the ground for the web application (callback functionality) to be accessible via PHP $_GET[] arguments.

    So, sorry not to have moved off “tool” (web application) work today, but it is very important to try to think of most/all eventualities you can imagine, ahead of the time when you get to the integration tasks the other way around, that is, the integration from the viewpoint of the software acting as “parent” or “co-operative peer” to your Calendar (event) “tool” web application.

    The reshaped PHP code now additionally catering for email “messaging” functionality you could call ics_attachment.php, which changed in this way, able to be run with this live run link. We hope you try out the new email functionality yourself.

    Calendar iCal Integration Timezone Tutorial

    Calendar iCal Integration Timezone Tutorial

    You might have thought with yesterday’s Calendar iCal Integration Primer Tutorial‘s emphasis on timezones we’d have …

    • had too much
    • seen too little
    • invited Goldilocks for some porridge

    … but time is quite a complex scenario on Earth, when it comes to timezones for at least two reasons, one being a functional improvement, and one being to fix a bug, that being …

    1. things like WebEx or Skype or GoTo Meeting are not tied down by geography and you may want Calendar functionality to reflect this, or you may also want it to cater for airplane departure and arrival times in various timezones around the world, and it would be best if the HTML form user entry phase catered for a user specifying a date and time not necessarily in either of their local timezone nor the GMT timezone (of the iCal “Z” property special interest) … is the functional improvement, whereas …
    2. we had a bug, leaving off from yesterday’s work with timezones whose GMT offset involved half hour differences … and yes, that happens quite often … and the bug will occur as of yesterday’s code when you come to use those PHP DateTime object add and/or sub methods where the PT[offset]H argument has an [offset] involving a decimal point, so it behoves us to update that relevant PHP code snippet for you, again, below, regarding that (and remind … forgot yesterday … that $ts variable is a user HTML form passed date and time) …

      $di="PT" . str_replace("-","",("" . $start_end_offsets[$thisi])) . "H";
      $parsed_date = DateTime::createFromFormat('Ymd:His', $ts);
      if (strpos(("" . $start_end_offsets[$thisi]), "-") !== false) {
      if (strpos($di, ".") !== false) {
      $parsed_date->sub(new DateInterval(explode(".",$di)[0] . "H"));
      $parsed_date->sub(new DateInterval("PT30M"));
      } else {
      $parsed_date->sub(new DateInterval($di));
      }
      } else {
      if (strpos($di, ".") !== false) {
      $parsed_date->add(new DateInterval(explode(".",$di)[0] . "H"));
      $parsed_date->add(new DateInterval("PT30M"));
      } else {
      $parsed_date->add(new DateInterval($di));
      }
      }
      $outts = $parsed_date->format('Ymd:His');

    Now allowing for the first idea above is not as involved as you may think, but only if you think serverside PHP, rather than think it will be easy with clientside Javascript. And what makes it a doddle, generally, are all those Open Source contributors to knowledge out there, and those great computing program language documenters out there exemplified in their brilliance with this totally useful link to the PHP timezone_identifiers_list and PHP DateTimeZone object method getOffset method links. So we allow the user to enter any of …

    • Local
    • GMT
    • Any of the half hour timezone numerical offset (indicators) from -24 to 24
    • Any of the timezone names as per those PHP methods above, with valid continental prefix names

    … to define the start and end date and time parameters to express for their Calendar iCal Event that they define. Along the way we also add in dropdowns and HTML input type=number (year) elements to help for those not so keen on keyboard entry.

    Guess you’d say we are still on the “tool” feel of the web application, but aim to move more on the “integration” front into the future.

    Here is the renewed PHP code you could call ics_attachment.php, that changed in this way, able to be run with this live run link. We hope you try it out for yourself, especially as we’ve added some Google Chart Map Chart linking of the “when” and “where” of defined timezone thinking, via the use of PHP’s DateTimeZone object method getLocation, as you can see happening with today’s tutorial picture.

    Calendar iCal Integration Primer Tutorial

    Do you remember us talking about the ICS extension file when we presented WebEx Prerecording Primer Tutorial as shown below? It is an integration input to working with iCal Calendar software.

    So here we are at a “when” of life tutorial, which is always an interesting exercise in our book. And “book” could be the go for an application to use this type of functionality. When you “book” something, you’d often want to remind yourself and/or others of such an event. But for now, we are concentrating on making a “tool” type of web application that will suit future purposes.

    We’ve built a web application around the useful logic presented in this great Git repository today, writing our code in PHP, because you are dealing with header manipulation here centering around …


    header('Content-type: text/calendar; charset=utf-8');
    header('Content-Disposition: attachment; filename=rjmprogramming-event.ics');
    echo $ical;

    … where the PHP variable $ical contents has been pieced together in response to a callback from an earlier HTML form execution of the same ics_attachment.php code where the necessary details are collected off the user.

    If you try the live run you’ll probably glean that most of our concern centered around the date and time, regarding timezone use so that we …

      var dd=new Date();
      var qw=eval((eval(dd.toTimeString().replace('-',' ').replace('+',' ').split(' ')[2]) - eval(dd.toTimeString().replace('-',' ').replace('+',' ').split(' ')[2] % 100)) / 100) + eval((0.0 + eval(dd.toTimeString().replace('-',' ').replace('+',' ').split(' ')[2] % 100)) / 60.0);
      if (dd.toTimeString().indexOf('+') != -1) qw=-qw;
      document.getElementById('tz').value=qw;
    2. Javascript’s Date object’s toTimeString method (as shown above) to glean the local timezone offset, and its opposite
    3. PHP’s DateTime object …

      $di="PT" . str_replace("-","",urldecode($_POST['tz'])) . "H";
      $parsed_date = DateTime::createFromFormat('Ymd:His', $ts);
      if (strpos(urldecode($_POST['tz']), "-") !== false) {

      $parsed_date->add(new DateInterval($di));
      }
      $outts = $parsed_date->format('Ymd:His');

    4. PHP’s DateTime object’s createFromFormat constructor method (as above) to create a DateTime object from the passed through user details
    5. PHP’s DateInterval object
    6. PHP’s DateTime object’s add and/or sub methods (as above) to create a DateTime object with a DateInterval offset to UTC (or GMT) (expressed in hours)
    7. PHP’s DateInterval object’s format method (as above) to end up with a UTC (or GMT) expression of date and time to be placed into the rjmprogramming-event.ics iCal message

    We’ll probably be revisiting with improvements soon, but we hope you try it for yourself.

    WebEx Prerecording Primer Tutorial

    We’ve been trying out WebEx (by Cisco) prerecording as a video conferencing idea as an alternative to …

    … regarding video conferencing products we’ve tried at this blog.

    Have to say, WebEx is great, even with respect to the “wide eyed and bushy tailed” reaction “this little black duck” has to all these networky communicaty ideas on the net (at least we spelt “net” correctly).

    Have to thank my wife, Maree, for her expertise and the facilities her company, Thomson Reuters, supplies for the serving of WebEx recordings … thanks everyone. Have been assured they are periodically deleted, and my lame impersonations of the old “ducks on the wall” can rest in peace shortly.

    And so, we have a slideshow starting with a WebEx email link to join a meeting, and we pan down the email to show you other WebEx functionalities, such as adding a Calendar reference to the meeting time, and though we haven’t shown you detail here, rest assured it handles timezone scenarios very well, unless you lie about living in Antarctica, that is … sorry, scientists in Antarctica reading this blog posting … all 237 of you.

    During this “earlier than today exploration of WebEx” session the necessary software installs just happened for this MacBook Pro Mac OS X laptop as if we were shelling peas … it’s always good to have some handy when installing any software. So we won’t show you this unless we deem it essential at a later date. You can perhaps do as I did, and ask a real WebEx user invite you to a meeting, to set yourself up. In fact, today’s session meeting creation time you may notice is well in the past from that earlier introductory learning session Maree and I had, and you can bring back up that old email, and resurrect that meeting again and again, if you like … am not sure if there is an expiry date on this too, like with server stored WebEx prerecordings.

    So also rest assured, WebEx handles …

    • video via webcam on your device
    • audio via microphone on your device (“Use Computer”) or via a phone line
    • the synchronization of the two above
    • mobile devices

    Did you know?

    A .ics extension file, as you can see being used as an email attachment file extension in is, as explained in this link‘s sublink …

    ICS is a global format for calendar files widely being utilized by various calendar and email programs including Google Calendar, Apple iCal, and Microsoft Outlook. These files enable users to share and publish information directly from their calendars over email or via uploading it to the world wide web.

    … as helping interface meetings to online calendar appointments. Cute, huh?!

    • relative URLs (to the RJM Programming domain) … and we see why we may have left this like this … we wanted to allow for image file specifications … something quite involved (but might be contemplated in a reduced functionality sense into the future …) regarding the first of two new URL modus operandi additions to functionality, those being …

    Image Conversions via PHP GD URL Tutorial

    The PHP inhouse Image Converter web application last talked about at Image Conversions via PHP GD Overlay Reveal Tutorial got a revisit today. It’s been more than two years, and that amount of separation sometimes gives you the chance to “go back to square one” and not be caught in amongst the “labyrinth of thought” as you get too far into complex optional logics you might apply to a web application project.

    And what stood out to us, on this revisit? It was the image input options that immediately stuck out to us, in that it used to be limited to …

    • relative URLs (to the RJM Programming domain) … and we see why we may have left this like this … we wanted to allow for image file specifications … something quite involved (but might be contemplated in a reduced functionality sense into the future …) regarding the first of two new URL modus operandi additions to functionality, those being …
    • absolute URL single image file … and …
    • image data URI single image

    Of course, should the absolute URL web servers allow such access, this opens up whole new vistas of functionality possibility here.

    Both new URL modus operandi above used an HTML iframe (shown along with an HTML form referenced later, also) …

    <?php echo ”

    <iframe style=display:none; id=ifi name=ifi src=./convert_wildcard.php></iframe>
    <form method=POST action='/convert_wildcard.php' target=ifi style=display:none;>
    <input type=hidden name=absimg id=absimg value=''></input><input id=sabsi type=submit value=Submit style=display:none;></input></form>

    “; ?>

    … but in two interestingly different ways … well, you had to be there!

    absolute URL single image file
    <?php echo ”

    function lookforabsolute(ino) {
    if (ino.value.indexOf('data:') == 0 && ino.value.indexOf('image/') != -1) {
    document.getElementById('absimg').value=ino.value;
    document.getElementById('sabsi').click();
    } else if (ino.value.indexOf('//') != -1) {
    ino.title=ino.value;
    document.getElementById('ifi').src='./convert_wildcard.php?absimg=' + encodeURIComponent('http://' + ino.value.split('//')[1]);
    }

    … meeting up with receiving PHP logic, skeletally …

    // Perform necessary $_POST scenario populating of $gabsimg
    }
    if ($gabsimg != '') { //isset($_GET['absimg'])) {

    }
    }

    $gabsimg=$_POST['absimg'];
    if (strpos(('~' . $gabsimg), '~data') !== false) {
    $dcont=str_replace(' ','+',urldecode($gabsimg));
    if (strpos($dcont, 'image/') !== false && strpos($dcont, ';base64,') !== false) {
    $inext=strtolower(explode(';base64,', explode('image/', $dcont)[1])[0]);
    $imgname='/tmp/mycw_' . server_remote_addr() . '.' . $inext;
    file_put_contents($imgname, base64_decode(explode(';base64,', $dcont)[1]));
    echo '<html><body onload=" parent.document.getElementById(' . "'ispec'" . ').value=' . "'" . $imgname . "'" . '; parent.document.getElementById(' . "'ispec'" . ').title=' . "''" . '; "></body></html>';
    exit;
    }
    }
    }
    if ($gabsimg != '') { //isset($_GET['absimg'])) {
    // Perform necessary image URL processing here adjusting parent.document.getElementById('ispec') in the process, if not already done above (and not getting here)
    }

    ?>

    … the most obvious reason for divergent approaches happening here being that data URIs are large and need $_POST[] form navigation while absolute URLs are short enough to use the simpler $_GET[] approach in the changed convert_wildcard.php‘s image conversion PHP web application.

    Image Conversions via PHP GD Multiple Actions Tutorial

    We’ve waited a while preparing for today’s release of “multiple actions” functionality onto yesterday’s Image Conversions via PHP GD Transformations Tutorial. From how we see it we had a choice of two approaches to delivering this new functionality …

    • start using select (ie. dropdown) element multiple attribute approach … but, especially because we are separating GD “Filters” into one dropdown and “Transformations” into another, we think it would be better to …
    • start prefixing ✔ (&#10004; tick) emoji to selected action(s) to apply to any images involved in the conversions

    The ✔ (&#10004; tick) emoji was enough for us, yet we wanted to indicate to the user the order of actions they’ve entered. To do this we were helped out by Javascript sort methodology used in …

    newih+=sopta[ioj] + '</option>';
    }
    insel.innerHTML=newih;
    insel.value=sv;
    }

    “; ?>

    … accepting the GD “Filter” dropdown object as a parameter. But how is that going to help when “action” titles will just determine the sort order? Well, the select (ie. dropdown) element here is made up of …

    <?php echo ”

    <option value=\”action_desc\”>Action Desc</option>

      curl "http://www.rjmprogramming.com.au/convert_wildcard.php?command=wh*.*g*+-q+76+-negate+.jpeg"

      open http://www.rjmprogramming.com.au/temphtml.html
      … to see results. Omit the open word for Windows. You have up to the next minute to do this.

      … and a quick witted user will copy and paste that open http://www.rjmprogramming.com.au/temphtml.html quickly enough to see a webpage offering image download functionalities

    … in the changed convert_wildcard.php‘s image conversion PHP web application.

    Did you know?

    With that last “rjmprogramming.com.au” curl scenario it occurs to us, you could optionally do a multiple command (or use type ahead buffer on Windows) like …


    curl "http://www.rjmprogramming.com.au/convert_wildcard.php?command=wh*.*g*+-q+76+-negate+.jpeg" ; open http://www.rjmprogramming.com.au/temphtml.html

    … for a 99% chance of success without having to worry about the “too quick” copying and pasting in less than a minute caper! Blurb output will correct you if temphtml.html is not the go.

    Or think procedural scripting where Windows has *.bat batch files and macOS or Linux have shells like sh or bash or csh or ksh (our favourite, called Korn Shell). A scheduled procedural crontab command action part could be a Korn Shell one liner like …


    ksh -c 'curl "http://www.rjmprogramming.com.au/convert_wildcard.php?command=wh*.*g*+-q+76+-negate+.jpeg" ; open http://www.rjmprogramming.com.au/temphtml.html'

    Then a Korn Shell script we’ll call “daily.ksh” on macOS or Linux could contain …


    #!/bin/ksh
    curl "http://www.rjmprogramming.com.au/convert_wildcard.php?command=wh*.*g*+-q+76+-negate+.jpeg"
    open http://www.rjmprogramming.com.au/temphtml.html
    exit

    … then, thinking macOS or Linux, make it (perhaps too) executable via …


    chmod 777 daily.ksh

    … and make happen via …


    ./daily.ksh

    Image Conversions via PHP GD Filters Tutorial

    Once in the (PHP) GD-land of yesterday’s Image Conversions via PHP GD Primer Tutorial, you’d be mad not to facilitate some image filtering which GD is so good at. And so, we have included an optional usage dropdown as per …

    … into the mix. We add this select element “dropdown” within the HTML form method=POST action=”Here’s looking at you kid” arrangement. Initially it gets assigned just an ID attribute, with no NAME attribute, which is an ideal arrangement when functionality is optional. And so, if the user chooses a real “filter” here it gets assigned an appropriate NAME attribute as per the PHP’s Javascript dropdown onchange event logic …

    function zoomsame(tvo) {
    var tv=tvo.value;

    Image Conversions via PHP GD Primer Tutorial

    Regular readers at this place will know about our admiration for ImageMagick and its command line (“convert” for macOS and Linux and “magick.exe” for Windows) image conversion functionality. Even so, ImageMagick is not capable of …


    convert filespec*.*g* *.jpeg

    … type of image conversion, in bulk, kind of processing (which Gimp offered with its sadly departed Bimp conversion software in the past). But tailored PHP use of the GD (image manipulation) library, helped out by (good ol’) PHP glob, is!

    And so, we’ve written a “proof of concept” converter that you can run at the RJM Programming domain, but we’d recommend for use with an Apache/PHP local web server like MAMP is! (Two in one blog posting is a record … is!)

    Get into MAMP, and you might want to download convert_wildcard.php PHP source code to MAMP’s Document Root folder. Else, try it here or below …

    Haiku Image Tutorial

    Haiku Image Tutorial

    Were you around when Python Cowsay API Cartoon Speech Media Tutorial‘s “genesis tutorial” called Python Cowsay API Primer Tutorial intimated …

    … with an integration purpose in mind

    ? And then, sometime between then and now were you a “Doubting Thomas” thinking we’d forgotten about that statement? And while we’re at it, where were you on February 6, 2025 03:01 AEST?

    I’m conflicted if your answers are “No” and “Robbing a bank” but, be that as it may, “we did have an integration purpose in mind” and we’ve come back to it via Haiku poetry, and a web application we wrote some time ago regarding them, and it interfaced to the theme of “the integration purpose in mind” … well you had to be there, said Putricia?!

    Yes, it’s the case that hoping for the umpteenth re-researching whether anything manageable Linux wise can match what the great macOS say command has done for Speech to Text relations since Audrey Hepburn’s speech … and coming back with a “No” yet again … we started looking at it a bit more laterally and thought 😜😜 …

    But what would the Cow say?

    But seriously, no, we just stumbled onto the wonderful cowsay Python API / Command-line tool and wanted to … thinking laterally … have “cowsay” smarts be included into our changed macos_say_record.php PHP Voiceover inhouse web application, itself interfaced to by our changed haiku_animated_gif.html Haiku creating inhouse web application you can also try below …

    … so that our changed latest draft can interface in a popup window scenario.

    As soon as a web application talks about image slides, as we have been dealing with allowing for the creation of cartoons with our recent cowsay Python API / Command-line tool interfacing PHP web application, maybe as Louis Lumière did many years ago, it brings out media thoughts regarding “moving pictures”.

    Text to Image via ImageMagick Primer Tutorial

    Why would a “Primer” tutorial point at a “well along the way” one? Well, a few reasons really …

    Yes, the great ImageMagick (and we’re using it’s command line “convert” command here to make this happen) can convert text to images (ie. HTML img elements). Now, we’re not saying you always get perfect matches here, but it is akin to mere mortal dreamers think of as “intelligent scanning”. So, we wanted to have this sidetrack, and we will be resuming “normal transmission” shortly?!

    We’ll leave you with some cowsay.php new relevant PHP code to ponder …

    We’ve long been interested in online web application ideas that end up with a half decent cartoon the user can create, and share, themselves. “Half decent” becomes “fully decent” with a user who has a great imagination.

    We discovered an interesting Open Source Python API / Command-line tool called cowsay which we installed up at our AlmaLinux web server via …


    pip install cowsay

    … with an integration purpose in mind, so thanks.

Before integration, though, we want to test it via a new PHP supervisor on exec method Linux command line interfacings to cowsay.
