In this world we all look up at the same …

• Sun
• Moon

… as our “usual companions” of space. One is tempted to say G’Day but we’re too scared of misspelling it, so we’ll just say …

Good Morning Sunshine

… to welcome today’s new Geography Quiz game mode …

• Country Capitals Game
• In the Hour Game
• Languages Game
• In the Timestamp Game
• Geographicals Game
• Crow Fly Game
• Bearing Game … and today we present …
• Noon Sun Angle Game

Yes, astronomers (and many cultures throughout history, before, it should be said) know a lot about the relative positions of the Earth with respect to the Sun (and Moon) especially, and we retrace much of the way we created the PHP Sun Information Software Integration Tutorial. So much so, that we left the Sun’s styling to be expressed just below our draggable “p” element, in a new HTML iframe element, with the following “onload” event logic …


function sunangle(iois) {
if (iois != null) {
var aconto=(iois.contentWindow || iois.contentDocument);
if (aconto != null) {
if (aconto.document) { aconto = aconto.document; }
if (aconto.body != null) {
if (iois.src.indexOf('longd=') != -1 && iois.src.indexOf('latd=') != -1) {
if (aconto.body.innerHTML.indexOf('): (') != -1) {
sunangleblurb=aconto.body.innerHTML.replace(aconto.body.innerHTML.split('): (')[1].split(')')[0], '?,?').replace(/\<br\>/g,' ').replace('" id="myh2"', 'margin-top:-40px;" id="myh2"');
document.getElementById('ddstyle').innerHTML+='<style> ' + aconto.head.innerHTML.split('<style>')[1].split('</style>')[0] + ' </style>';
if (1 == 1) {
aconto.body.innerHTML=sunangleblurb;
document.getElementById('isun').style.display='inline-block';
} else {
document.getElementById('source').innerHTML=sunangleblurb;
}
}
}
}
}
}
}


… that is tweaked so as not to give the game away, but displays information much as that PHP Sun Angle web application intended. The aim of this Noon Sun Angle Game mode of use, within our Geography Quiz theme, is to drop the draggable label above this Noon Sun Angle (and other) information into the correct of the nine Google Geo Chart country maps below, to score.

Further to the recent Javascript Lazy Evaluation Game Sharing Tutorial to make this happen, see our changed gradual_reveal_country_game.html‘s Noon Sun Angle and/or Bearing and/or Crow Fly and/or Geographicals and/or In the Timestamp and/or Languages and/or Country Capital and/or In the Hour Game web application, below too.

Did you know?

We can navigate using the Sun and stars. Land surveyors lacking two known co-ordinated survey marks can set up on one known survey mark and take measurements of the Sun (careful here not to directly look at the Sun) to determine an initial bearing (or azimuth), and off that swing an angle with their theodolites to begin a survey traverse.

In thinking about a sharing, via email or SMS, component on top of the progress of the recent Javascript Lazy Evaluation Bearing Game Tutorial, with our current …

• Javascript Lazy Evaluations themed …
• Drag and Drop themed …
• Geography Quiz themed …

… game modes we thought the best approach would be if a user could share with another the same Geography Quiz based question they have been asked, to compare notes.

Which begs the question?

What can give a game (or quiz) a random feel?

Well, with Javascript, we’re always using …


var arandom=Math.floor(Math.random() * anarrayofchoices.length); // anarrayofchoices is an array of choices and arandom ends up as an index into that array's contents


… types of statements … or variations on this style of statement. So we zeroed in on these and set about _unrandomising these places in the code, to, if asked, simulate that same random way the question was framed for the emailer …


var complex=location.search.split('simple=')[1] ? decodeURIComponent(location.search.split('simple=')[1].split('&')[0]) : '';
var drilldown=complex.split('_')[0];
var simple=location.search.split('simple=')[1] ? (drilldown == '' ? false : true) : false;

var mflist=drilldown + '_', mfcount=0;

var answer=Math.min(9, eval(Math.floor(Math.random() * 9) + 1)); // first example of use
if (complex.indexOf('_' + mfcount + '.') != -1) {
answer=eval(complex.split('_' + mfcount + '.')[1].split('_')[0]);
}
mflist+='' + mfcount + '.' + answer + '_';
mfcount++;


… used by new helping Javascript code …


<div id=das style=display:none;></div>
<script type='text/javascript'>
setTimeout(function() { document.getElementById('das').innerHTML+=("<a style=display:none; id=asms href='sms:&body=" + encodeURIComponent(document.URL.split('#')[0].split('?')[0] + '?simple=' + encodeURIComponent(mflist)) + "'>SMS</a>"); document.getElementById('bsharesms').style.visibility='visible'; }, 18000);

Let’s just suppose you’ve got a “hardy crow” (like those in Javascript Lazy Evaluation Crow Fly Game Tutorial) and it doesn’t mind “a bit of chill” on occasions. To minimize the distance it flies to get to a given destination in that shortest distance (or “great circle distance” discussed yesterday) it needs to set out at a particular bearing (or direction) where zero degrees is North and ninety degrees is East and 3 degrees? Glad you asked!

With this bearing being able to be calculated …


function great_circle_bearing(talis, gnolis, latis, longis) {
// Let ‘R’ be the radius of Earth,
// ‘L’ be the longitude,
// ‘θ’ be latitude,
// ‘β‘ be Bearing.

// Bearing from point A to B, can be calculated as,
// β = atan2(X,Y),
// where, X and Y are two quantities and can be calculated as:
// X = cos θb * sin ∆L
// Y = cos θa * sin θb – sin θa * cos θb * cos ∆L

var ourbrg=eval(eval(360.0 + eval(eval(eval(180.0 / Math.PI) * Math.atan2(
eval(eval('' + Math.cos(eval(Math.PI / 180.0) * eval('' + latis))) *
eval('' + Math.sin(eval(Math.PI / 180.0) * eval(eval('' + longis) - eval('' + gnolis))))),
eval(eval('' + Math.cos(eval(Math.PI / 180.0) * eval('' + talis))) *
eval('' + Math.sin(eval(Math.PI / 180.0) * eval('' + latis)))) -
eval(eval('' + Math.sin(eval(Math.PI / 180.0) * eval('' + talis))) *
eval('' + Math.cos(eval(Math.PI / 180.0) * eval('' + latis))) *
eval('' + Math.cos(eval(Math.PI / 180.0) * eval(eval('' + longis) - eval('' + gnolis)))))
)))) % 360.0);

return '' + ourbrg;
}

To be a crow on the Mercator Projection is to be the “moron” in oxymoron. Yes, have a read of Why is the ‘straight line’ path across continent so curved? Or do they have a “shot of Mercator” and move this way? Well, we’re not asking the class, this time!

But those distances of that direct way crows allegedly fly is able to be calculated …


function great_circle_distance(talis, gnolis, latis, longis) {
var ourdist=0.0;
var rgnol=eval((gnolis) * Math.PI / 180.0);
var rtal=eval((talis) * Math.PI / 180.0);
var rlong=eval((longis) * Math.PI / 180.0);
var rlat=eval((latis) * Math.PI / 180.0);
var deltalong = Math.abs(eval(((gnolis)-(longis)) * Math.PI / 180.0));
var acof = eval(Math.sin(rtal) * Math.sin(rlat)) + (Math.cos(rtal) * Math.cos(rlat) * Math.cos(deltalong)); // via //en.wikipedia.org/wiki/Great-circle_distance ... thanks
ourdist = eval(Math.round((Math.acos(acof) * 6371000.0) + 0.00001) * 100) / 100;
return '' + ourdist;

These days, online, you are probably used to seeing Geographicals presented as decimal degree Longitude,Latitude or vice versa, but we add a touch of interest by turning those decimal degree Geographicals into entries like …

The “Languages Game” concept would be really simple if every country had one spoken language, but the world does not work this way. But, do you remember when we last presented Fairy Story Chrome Dictation Punctuation Tutorial? There, we were referencing Text to Speech software that Google has demonstrated at https://www.google.com/intl/en/chrome/demos/speech.html (for you Google Chrome users out there). Well, it’s full of great ideas regarding …

• the mapping of a given Language name (along with its associated code) … to …
• one or more locale_s …
  

  In computing, a locale is a set of parameters that defines the user’s language, region and any special variant preferences that the user wants to see in their user interface. Usually a locale identifier consists of at least a language code and a country/region code. Locale is an important aspect of i18n.

… and this forms the basis of how we might map a language code back to a country code, for our Languages Game today.

Take a look at some new Javascript to help here …

Previous relevant Javascript Lazy Evaluation Game Scroll Into View Tutorial is shown below.

Within the changes involved in the recent Javascript Lazy Evaluation In the Hour Game Daylight Saving Tutorial you may have seen the change …


if (window.self !== window.top) { answer=answer; } else { document.getElementById('source').scrollIntoView(); }


What is the motivation for that change? Well, if a blog posting contains an HTML iframe pointing at our latest Country Capital or In the Hour Game web application, it would annoyingly scroll down to the webpage position of element document.getElementById(‘source’) in that iframe without the user having clicked any buttons. Dead annoying!

But then, can this same idea, or a similar scrolling equivalence help us out sometimes, on the other side of the coin? Well, yes, and that ability, encapulated in the logic of two clonish dropdowns …

• one dropdown up the top of the webpage … and another “clone” …
• dropdown to right in the middle of the table height_wise, roughly, as a position:fixed …
  
function overtoright(inspano) {
if (window.self !== window.top) { answer=answer; } else {
var rectxo=document.getElementById('mytable').getBoundingClientRect();
inspano.style.position='fixed';
inspano.style.left='' + eval(10 + eval('' + rectxo.right)) + 'px'; //'' + eval(-20 + screen.width) + 'px';
inspano.style.top='' + Math.floor(eval(rectxo.top + rectxo.bottom) / 2) + 'px';
inspano.style.zIndex='99';
inspano.style.display='inline-block';
}
return inspano;
}

  … element, so as to be within view more often

… helping to offer …

• scrolling positional possibilities, as above … is timely way to be able to help out …
• Geo Chart iframe scaling of itself and its contents …

Previous relevant Javascript Lazy Evaluation In the Hour Game Daylight Saving Tutorial is shown below.

Regarding yesterday’s Javascript Lazy Evaluation Country Game Hints Tutorial progress with the “In the Hour” mode of game play, we thought there would only be the rare annoyance regarding Daylight Saving alterations to the default timezone offsets to GMT time, but there were more than we realized, prompting us to start using codelines like …


var newd = new Date(new Date().toLocaleString("en-US", {timeZone: yourtzlist.split(',' + opts[eval('' + atry)].value + ',')[1].split('>')[1].split('<')[0]}));


… to start working out timezone offsets in the client world (as you may remember us discussing with SVG Network Clock Minimize Tutorial in recent times) checking on those PHP timezone derivations we default to, but might be wrong by an hour, regarding Daylight Saving timezone arrangements in place for certain times of the year in some countries …


var cinthehourspush=(('0' + eval(eval(eval(eval(yourtzlist.split(',' + opts[eval('' + atry)].value + ',')[1].split('"')[0].replace('+','')) + uhour) + 24) % 24)).slice(-2) + ':' + ('0' + umin).slice(-2));
var newd = new Date(new Date().toLocaleString("en-US", {timeZone: yourtzlist.split(',' + opts[eval('' + atry)].value + ',')[1].split('>')[1].split('<')[0]}));
var newh=eval(('' + newd).split(':')[0].split(' ')[eval(-1 + ('' + newd).split(':')[0].split(' ').length)]);
if (cinthehourspush.indexOf('' + ('0' + newh).slice(-2)) != 0) {
var oldh=eval('' + cinthehourspush.split(':')[0]);
if (oldh != newh) {
//alert('uhour=' + uhour + ' and oldh=' + oldh + cinthehourspush.substring(2) + ' goes with ' + yourtzlist.split(',' + opts[eval('' + atry)].value + ',')[1].split('"')[0] + ' and newh=' + newh + cinthehourspush.substring(2));
if (newh < uhour && newh == 0 && uhour == 23) {
sofarhrs+='+' + eval(24 - uhour) + ' ';
} else if (newh > uhour && newh == 23 && uhour == 0) {
sofarhrs+='-' + eval(24 - newh) + ' ';
} else if (oldh > uhour) {
sofarhrs+=yourtzlist.split(',' + opts[eval('' + atry)].value + ',')[1].split('"')[0].replace('' + eval(oldh - uhour), '' + eval(newh - uhour)) + ' ';

}
}
gcinthehourspush='' + ('0' + newh).slice(-2) + cinthehourspush.substring(2);
}


We’ve also added in more linking that adds on to yesterday’s existant …

• Placename links to Wikipedia … so that now we also have …
• Country links to Wikipedia … and …
• TimeZone information links added to the “just after” times shown

Also added, today, is another hint, we’ve called “Regions”, which colour codes Geo Charts (albeit in a subtle way) according to those Regional first words in a TimeZone name like …


Asia/Singapore


… where that “Asia” is differentiated via our new arrays …


var rcolmaps=['Africa','Asia','Europe','GMT','America','Pacific','Arctic','Atlantic','Indian','Australia','Antarctica'];
var rcolmapred=['15','45','55','55','75','85','95','a5','b5','d5','e5'];


We also thought “right now” was a bit of a waste of time, when we could show the user (a phrase like) “on Monday” (ie. on day of the week).

And so, yet again, we hope you try the changed gradual_reveal_country_game.html‘s Country Capital and/or In the Hour Game web application, below too, yourself?!

Previous relevant Javascript Lazy Evaluation Country Capital Game Context Tutorial is shown below.

The improvements, today, onto yesterday’s Javascript Lazy Evaluation Country Capital Game Tutorial‘s “Country Capital Game” web application revolve around “context” …

• there’s the “context” between land masses and sea … as well as …
• there’s the “context” between country and world view

… both of which take us further into the realms of Google Chart Geo Chart usage, even “unique usage for us”, as far as the first one above.

Regarding the “context” between land masses and sea, wouldn’t it be good, on the map to colour the land with a greener tinge? Anyone, anyone, is green the go? Yes, 3GPP, or is that CP3O, disguised as R2D2 … anyway … yes, we could …

• isolate the inherent map contents in its SVG guise … but if we could just censure the content here just that teensy weensy bit, now …
• we could torture that SVG to reveal its fill colourwe could do research and development, via a web browser web inspector, into that SVG’s path element fill colour … spoiler alert … #f5f5f5 (grey) … and …
• liquidate its assetsgently coerce the map into thinking its SVG path element fill colour should be #c5f5f5 (our greenish tinge)

Thanks, can I call you 3^o?


function hashit(iois) {
if (iois != null) {
var aconto = (iois.contentWindow || iois.contentDocument);
if (aconto != null) {
if (aconto.document) { aconto = aconto.document; }
if (aconto.body != null) {
aconto.getElementById('myh').style.display='none'; // aconto.getElementById('chart_div').scrollIntoView();
// Thanks to https://stackoverflow.com/questions/6088409/svg-drop-shadow-using-css3

}
}


Oh, okay then. Sorry. Thanks, 3GPP_{subsection III}! You do get straight to the point, there!

And then, regarding the “context” between country and world view, we have a two part improvement to matters here, we feel. Firstly, we hope to help contextualize “where in the world” is a country, and secondly, we wanted to “value add” for these popup windows we might open as the user hovers over a “country map” cell (filled with iframe Google Chart Geo Chart content), otherwise such interventions can be annoying, and we hope we’re not making the game too easy by adding to …

• the existant onmouseover event creating popup window … now …
• identical #c5f5f5 fill_ed land mass “country map” … our newly added …
• “world map” view of that same country, highlighted

… for context …

Previous relevant Javascript Lazy Evaluation Game Involvement Tutorial is shown below.

Yes, we’ve decided to involve the Lazy Evaluation and async and await and Promise and setTimeout Javascript logic of yesterday’s Javascript Lazy Evaluation Promise Tutorial into a Drag and Drop mathematics game for Small Integers from 1 to 9. Can you hear Alice in the middle room?!

Our “mathematical sentences” to solve in this game, where the operators can be + or – or / or * or %, and integer is number from 1 to 9, can be …

• hard … made up of …
  

  integer operator	integer operator	integer operator
  integer operator	integer operator	integer operator
  integer operator	integer operator	integer

  … or …

• simple … made up of …
  

  integer	operator	integer
  operator	integer	operator
  integer	operator	integer

… parts to the “mathematical sentence” revealed gradually, using those aforesaid mentioned Javascript techniques, the less revealed as the user answers, the bigger the score, if correct.

Previous relevant Javascript Lazy Evaluation Promise Tutorial is shown below.

Working on yesterday’s Javascript Lazy Evaluation Follow Up Tutorial subject matter further today, we’d like to introduce a glossary of terms for beginners here …

• async
  function

  The async function declaration creates a binding of a new async function to a given name. The await keyword is permitted within the function body, enabling asynchronous, promise-based behavior to be written in a cleaner style and avoiding the need to explicitly configure promise chains.

• await
  operator

  The await operator is used to wait for a Promise and get its fulfillment value. It can only be used inside an async function or at the top level of a module.

• Promise
  object (thenable)

  The Promise object represents the eventual completion (or failure) of an asynchronous operation and its resulting value.

• Lazy
  syntax (function)

  Lazy evaluation means to delay the evaluation of an expression until it’s needed. Lazy evaluation is sometimes referred to as call-by-need.
  
  The opposite of lazy evaluation is an eager evaluation. It’s an evaluation strategy used in most programming languages.
  
  Lazy evaluation makes it possible to:
  
  define potentially infinite data structures
  increase performance by avoiding needless computations
  customize iteration behavior for data structures that want its elements accessible to the public

• setTimeout
  function (global)

  The global setTimeout() method sets a timer which executes a function or specified piece of code once the timer expires.

Meanwhile you can (re-)try our Javascript modified lazy_async.htm web application in a new tab or below …

Previous relevant Javascript Lazy Evaluation Follow Up Tutorial is shown below.

Further to yesterday’s Javascript Lazy Evaluation Primer Tutorial‘s subject matter regarding Lazy Evaluations and Javascript async functions, we’ve stumbled upon another great resource, thanks, from which we can base, to develop a web application, we’re hoping.

Within this “proof of concept” code basis you will find setTimeout (timer) references to Lazy Evaluations like …


setTimeout(() => {
aminterested='Just';
resolve("fast");
consolelog("fast promise is done");
aminterested='';
}, 1000);


… as a function that …

• attempts to start in one second’s time …
• as needed that function is performed

The possibilities here are multifaceted, and varied, and definitely worth experimenting with, within Javascript client work.

So our starting web application can be tried in a new tab or below …

Personally, we’re more your “eager” types, but we’ve had help in the past from brilliant “lazy” types too, especially when we presented Selection API and Clipboard API Tutorial, and so, we honed in on some Javascript “Lazy Evaluation” code, and put together some status information shown regarding timings and calls with respect to Javascript …

• “Lazy Evaluation” in Javascript … classical syntax goes …
  
f = () => expression;

  … and …
• async function in Javascript … classical syntax example goes …
  
function resolveAfter2Seconds() {
return new Promise((resolve) => {
setTimeout(() => {
resolve('resolved');

async function asyncCall() {
console.log('calling');
const result = await resolveAfter2Seconds();

… and were happy to discover the Promise object talents of …

• sleeping … allowing for …
• multitasking
• doing … all using clientside Javascript

… very interesting. The serverside languages such as PHP make it a doddle to multitask (via sleep) but Javascript sleep has not always been a straightforward proposition, until we could promise, that is!

Today’s await.html‘s use of it to sleep and in between show …

1. analogue clock … and …
2. Dams of the USA (via dams_usa.html changed this way)

… asynchronously both doing their own thing while the await.html works away in the background too, feeding off “child 2” clicks of “child 1” above to know when to say how long the dams took to load. Yes, the “child 2” “onload” event, alone, cannot help determine this, but more “drilling into” the inner workings of the code behind “child 2″‘s progress element, via …

We had occasion to revisit the card game (and more) recent web application exploits highlighted in the recent Just Javascript Card Game Cursor Tutorial thread of blog postings and shaped to play Bridge via …


https://www.rjmprogramming.com.au/HTMLCSS/cards_usefocus.html?card_memories=04.1:ara


… and was “personally relatively” happy up to the first Javascript prompt popup window. Huh?! What’s with “personally relatively”? Can I be serious? Well, I’m insulted!

The thing is, I don’t mind, when I’m writing the code (funny about that?!) very complex and convoluted prompt window instructions and options. But …

• not everybody is willing to read such long diatribes
• actions can speak louder than words, so we figure between those first two prompt windows in a Bridge or 500 card game, it would be beneficial to show a “progress cursor” (ie. usually associated with the user waiting for a process to finish) between the first and second prompt windows to help show the players there could be waiting and irrelevant players turning away should all four players want to play fairly in their game

It was an interesting Javascript coding exercise …

1. (sort of) overload the “prompt” function with our inhouse “superprompt” function via …
   • globally replace ” prompt(” with ” superprompt(“
   • globally replace “=prompt(” with “=superprompt(“
2. add the following Javascript code …
   
var aheadoffirst=(('' + document.URL.replace('?', '&').indexOf('&card_') != -1) ? trueize() : 0);

function dbcpp() {
if (aheadoffirst == 2) {
document.body.style.cursor='progress'; // between first and second prompt windows
setTimeout(dbcpp, 1000);
} else if (aheadoffirst == 0) {
document.body.style.cursor='pointer';
} else {
document.body.style.cursor='pointer';
setTimeout(dbcpp, 1000);
}
}

function trueize() { // bit like a promise
setTimeout(dbcpp, 1000);
return 1;
}


function superprompt(opone, optwo) {
if (aheadoffirst == 3) {
document.body.style.cursor='pointer';
aheadoffirst=0;
} else if (aheadoffirst != 0) {
aheadoffirst++;
if (aheadoffirst == 3) {
document.body.style.cursor='progress'; // between first and second prompt windows
}
}
return prompt(opone, optwo);
}


… which reminded me that we need to learn some more about the promise object.

See this in action with the changed cards_usefocus.html code behind the “Just Javascript” Memories Card Game or live run with single window (good for mobile) or default live run (for your platform, and if non-mobile it will try child popup windows).
