Python GraphViz via PHP on AlmaLinux Permissions Tutorial

Did you guess, regarding the Python Graphviz via PHP work of yesterday’s Python GraphViz via PHP on AlmaLinux Tutorial, we were experiencing File Permission issues?

Well, yesterday, regarding the Python Graphviz via PHP work of yesterday’s Python GraphViz via PHP on AlmaLinux Tutorial, we were experiencing File Permission issues.

We thought we’d move the Python, via PHP processing, totally into the purview of the web server administration owner, by involving a …

Korn Shell *.ksh … supervised by …
crontab … pointing to …
ksh -c 'for i in `find /home/rjmprogr/public_html/ -name "subgraph_example_*.ksh"`; do ksh -c `echo $i`; done'
… very regularly

… arrangement, but even that failed, in a first incarnation using /tmp/ placement of the Korn Shell file. “Permission denied”, again. Running a Korn Shell from /tmp/ on AlmaLinux must be a no-no, so moved the place to be AlmaLinux web server’s Document Root place, and then things started happening, in the changed subgraph_example.php Python GraphViz using web application.

Python GraphViz via PHP on AlmaLinux Tutorial

Do you remember reading, with PHP Image GraphViz via Pear on AlmaLinux Primer Tutorial below, our outlining three known GraphViz guises …

the recent, alas now deprecated, Google Charts Image Charts GraphViz option means of drawing SVG graphics within an HTML image … we’ve known about before about yesterday …

today’s interest, that being PHP Image GraphViz via Pear on AlmaLinux install, via the AlmaLinux cPanel “Module Installers” Pear installer page, means by which we can use GraphViz calls in PHP code … and, for the future …

GraphViz installs for Python via pip

…? Well, today, we start down the road of …

installing Python GraphViz package via …
pip install graphviz
… then …
getting great help from https://graphviz.readthedocs.io/en/stable/, thanks, as the Python code basis we call subgraph_example.py … and …
used and remoulded by our overseeing PHP subgraph_example.php Python GraphViz using web application

… we need to work on more after this first draft start to another road of our GraphViz journey last talked about at PHP Image GraphViz via Pear on AlmaLinux Focus Tutorial.

PHP Image GraphViz via Pear on AlmaLinux Focus Tutorial

It reared it’s ugly head with the Animated GIF Creator here at RJM Programming (helped out by the great Jeroen van Wissen open source work, thanks). And with yesterday’s PHP Image GraphViz via Pear on AlmaLinux Recallable Tutorial it reared up again.

On non-mobile focus goes to the address bar on many web browsers unless there is a (nominally) visible input type=text or textarea next in line.

It’s hard to keep in mind except as it “rears up” in an annoying way, but if we’d thought back, yes, we allow in the linked list feel of revealing textboxes (or textareas) only as they are needed scenarios we allow for two blank ones to be (nominally) visible at any given time … not one … but two, presumably because there is a tiny Javascript DOM “refresh period” not short enough to stop the web browser “desperation measure” (of placing focus in the address bar) happening?!

Why the non-mobile mention? Well, on mobile, a user programming [HTMLelement].focus(); call has no affect, as the touch operating systems need control of focus arrangements, presumably?!

How can we forget? My liege, please accept my humble apologies?!

Why the (nominally) mentions? Well, we have, successfully, in the past, just arranged a (statically HTML placed) textbox (ie. input type=text) that sits outside the viewing screen but not (nominally) invisible (eg. style=’position:absolute;top:-200px;left:-200px;’) can help you avoid the focus going up to the web browser address bar.

So that’s that, and other progress today is to allow the emailing or SMS of a recalled URL Step arrangement via more options on that “Recall Dropdown” we started allowing for yesterday.

Please see this happening in our changed PHP coded My Recipe Steps web application you can also try below.

After yesterday’s PHP Image GraphViz via Pear on AlmaLinux Sharing Tutorial some readers may be curious to understand the distinction between …

email and SMS sharing … and …
inhouse intersessional sharing via window.localStorage (ie. like HTTP Cookies)

… over yesterday’s and today’s blog posting timings. Simply put, for us, we …

take a deep breath before starting intersessional window.localStorage work, as it is not to be sneezed at, as any sort of doddle (at least for us) … as well as …
since last intersessional window.localStorage work we’ve started using email and SMS sharing hashtagging arrangements that fit in, like a glove, with this intersessional window.localStorage work … so that …
even though, we write the code here in PHP, all this functionality is client based … which we like because …
get the idea correct, with careful forward planning and implementation, we’ll be able to apply similar such thinking into the future, whether that be for clientside only web applications and/or ones that call on serverside code (like PHP) … and …
if we can keep things just clientside more readers can be involved, we figure

If you’re wondering about the worry of any of this, it is to do with large title and/or URL link and/or ingredient type data whose data length could be huge, where most of our concern lies, and …

hashtagging (where data limits are so much longer) can help it remain as a clientside only solution environment (rather than relying on some form method=POST to a serverside (eg. PHP) receiver solution) …
window.localStorage is a step up from the HTTP Cookie style of intersessional (personal) storage as far as amounts that can be stored is concerned

What are we aiming for here, then, with our improvements?

extend the existant email and SMS functionality …

The term “GraphViz” …

Graphviz (short for Graph Visualization Software) is a package of open-source tools initiated by AT&T Labs Research for drawing graphs (as in nodes and edges, not as in bar charts) specified in DOT language scripts having the file name extension “gv”. It also provides libraries for software applications to use the tools. Graphviz is free software licensed under the Eclipse Public License.

today’s interest, that being PHP Image GraphViz via Pear on AlmaLinux install, via the AlmaLinux cPanel “Module Installers” Pear installer page, means by which we can use GraphViz calls in PHP code … and, for the future …
GraphViz installs for Python via pip

… in amongst many others we’ve seen programmers using … totally cute, totally useful!

It seems with our PHP Image GraphViz via Pear on AlmaLinux as what looks like a very much “pared down” version of the last mode of use above, that we add constructed graph node or edge or cluster objects, and form them into SVG based HTML image elements. It’s look got me thinking “Steps”, then “Recipe Steps”, and back, quietly, to “Any Old Steps” as the day got more generic.

At first we got, as far as Recipes go (and here we thank Italian Wedding Soup for today’s inspiration), to …

cooking steps showing as Image GraphViz edge graphic components (having arrows connect ellipses containing text, a bit like Speech Bubbles) … and then trying to face the “real world” a user interested in recipes might want to see happen …
an Image GraphViz node graphic component whose wording could be a user supplied recipe Title along with a “URL” attribute link, optionally user supplied (via our HTML div SVG hosting ondblclick event allowing its contenteditable=true attribute and onblur event means by which these optional additional data items can enter the “mix”, if you’ll pardon the pun), probably pointing back to the original recipe information ~~sauce~~source … and …
this title and/or “URL” and/or ingredient list (for example) can all be expressed as the “on hover” title attribute of the tailored user PHP webpage (yes, here we have PHP writing PHP) … and …
at least on Safari, given a recipe Title defined, we can arrange any browser context menu (ie. right click) over the HTML iframe hosted recipe content “Save Iframe As” option being able to download to a reasonably self explanatory download filename … and/or …
any web browser’s Add Bookmark functionality can be harnessed to help the user out in such a way that our PHP coded My Recipe Steps web application could end up being your one stop shop “Recipe Organizer” online?!

It’s Tuesday, in places around the world, looking back at yesterday’s Google Chart Image Chart Image Map Event Editing Tutorial. Can’t help but think we’ve forgotten something. Ah yes …

You talkin’ to me? You talkin’ to me? Meanwhile, back at the questions! Welcome back, Mr De Niro, sir. We hope your Tuesday is treating you well. (Rhetorical. Let it please be Rhetorical … oh dear God … it must be Rhetorical … it must be Rhetorical) We have news regarding “the dosh” (wink, wink) we were discussing the other day. You see …

Never rat on your friends and always keep your mouth shut. Really wish we could! Yes, Mr De Niro, sir, but, you see this means the rats are completely out of the picture, just leaving us with our money spinner. Right, Mr De Niro … sir.

There are three ways of doing things around here: the right way, the wrong way and the way that I do it. [Exeunt: Stage right] Well, that’s odd? Mr De Niro wasn’t interested in the quadrant nature to our problem solution …

We really like HTML image maps, and it occurred to us with yesterday’s Google Chart Image Chart Image Map Tutorial we were hiding its light under some bushel somewhere, because …

yesterday we introduced with only the onclick event coded for in the HTML area subelements to the map parent element … linked to an …

1. many more events than onclick can be defined as you define the area subelements … and here’s the kicker …
2. you can add area subelement event logic that, on paper, would cause interference with other event logic (ie. the same event type in an event bubbling through scenario) but it won’t if you, as a programmer, turn that use of the usemap attribute on and off like a tap

… which, to our mind, represents the bee’s knees of event management. So useful!

Do you like to come at explaining things in layers? Sort of like the analogy …

you start a project thinking of it in terms of “2D” … and then to move forward …
you spend a day making it work for “3D” (and keep the “2D” working as well)

… or …

you start a web application project thinking of only working via a URL entered on the web browser address bar … and then to move forward …
you spend a day making it work for serving the same purpose and/or a difference purpose called within an HTML iframe (and keep it working for the address bar way as well)

And so we look at a “picturesque” but “kinda dumb” (as far as “action items” go) image we have coming off the interfacing to Google Charts Image Chart. Where can we go here? Well, it would be kind of you to take it to the beach, but that’s not always a possibility now, is it?! Were you pulling my leg?! Tee hee.

Indeed, a young “picturesque” might like to go tap dancing, that is true. Sheeeeesh! But given the lesson is a Computing one, rather than Drama or Dance or Music or the Arts, maybe we would be looking for a way to use the picture in an enhanced way. Okay Kevin, we’ll try you. What do you think?

first tentative steps towards, on non-mobile platforms, allowing for text placement rubber banding

Why the trepidation? Well, so far, when the text is angled we can’t understand what results we are getting back from a call to [element].getBoundingClientRect() just yet.

Why is this needed? Again, with the questions! Well, Mr De Niro, you see, well, somebody might want to go onto that more complex annotating.

And why would they do that? Sheesh. Well, Mr De Niro, sir, you see, sometimes things happen in life, and well, fingers slip on keyboards, and mice get awfullllly nervous around screens these days.

Yeh, well, show us the money, wiseguy. Who’s is that question? And what’s with the questions? Well, you see, Mr De Niro, the money is if we can get PHP text placement for text at an angle, where it rotates from the middle of the text, to get a similar positioning to good ol’ … pardon, Mr De Niro … good and well respected Javascript transform rotations … not with a triple pike, Mr De Niro, but you’re awfulllllly close, Mr De Niro, sir … rather, we throw in a couple of translations … no, not Latin, Mr De Niro … of co-ordinates, Mr De Niro.

And that will bring in how much by next Tuesday? Back to the questions? Why so many questions? We think it’s a pretty big money spinner, Mr De Niro, sir, and we think you should come back next Tuesday, and we can show you the ropes. Sweat, oozing from the brow, as Mr De Niro exits stage left.

And just while we have a few minutes, here’s the updated Javascript parameterization …

Did you know?

Did you notice the inclusion of CSS styling …

? It styles an input type=number textbox where a placeholder is not really an option to explain a textbox’s purpose, and we do dislike set aside labels, these days. It’s also a way to explain the textbox for mobile users who do not get a hovering message to help. It’s also got an internationalization feel to it, using the degree sign emoji ° (ie. ° or that \u0080 UTF-16 Encoding style of definition suitable for CSS styling usage) to both associate the units we’d want, as well as that we are asking for an angle. Clockwise or anticlockwise, alas, comes down to user experience!

we’ve stopped closing off the text font size dropdown too early, allowing the user to mix it up with their annotations, and so …

We now recommend, for those users pushing the boundaries of functionality, to gather all their “inhouse annotations” together before any “graphical canvas annotations” are thought about.

Which begs the question …

Where do you get it?

Well, here, via … dare we say it?! … … via …

Mantissa Madness Monday

Both colour and degree counterclockwise angle became “Mantissa Madness Monday” tragics, a bit like moi, really?

How did we express these two measures?

colour can be derived at the 404.php end via mantissae that are 9 or more long where a number of the form rrrgggbbb is numerical and passed across to 404.php in the y co-ordinate mantissa … while … kind of crazily …
angle can be a set of zeros in the x co-ordinate mantissa represented by zero characters to the length of the angle from 1 to 359 in front of a pre-existant font size (in px) usage, from last “Mantissa Madness Monday” (us getting away with this because no font size should start with a zero)

Barracking for Hairtie United …
You little beauty, Untied!

And so, further to yesterday’s Google Chart Image Chart Circle Annotation Tutorial we have this non-mobile “Rubber Banding” inhouse annotation functionality included in our changed latest draft image_venn.html Google Chart Image Chart Venn Chart or Scatter Chart or GraphViz Chart or Pie Chart or Line Chart or Bar Chart or Candlestick Chart or Map Chart interfacing web application you can also try below.

But there’s more! Despite how long out of the day it takes to barrack for Hairtie United, there was a mobile matter we resolved. A slide in today’s animated GIF presentation shows the issue. On mobile platforms, with these inhouse annotations, it would immediately show a tiny annotation. There panned out to be two event programming related issues we needed to fix related to this problem …

change looking for a “touchstart” event, and instead look for a “touchdown” event for a document.body scope (else we might have restricted the “scope” to just document.getEleementById(‘myvenn’) as another approach (and you should note our event.stopPropagation() statements in lots of places as another research point for you)) because we are talking “discrete click” user behaviour we are targeting … as well as …

Did you know?

Well … we didn’t?! We happened to try the web application above on a tiny iPad and saw that HTML button elements with an innerHTML label containing a line feed ( ie. <br> ) only showed the top line, and, alas, for that button in question, the vital new information used to be on the second line. Hence our fix …

menu driven annotation functionality which can change that canvas look and underlying data … and …
the caller can keep track of this and arrange, or not, for these changes to be reflected back at its top left “img” element … the catch being …
the “within range of GET argument” limits are ruined by this introduction of graphical data, and so in agreeing to this, a user forgoes those simpler sharing and annotating functionalities of yesterday’s (and before) work … though your normal image sharing capabilities via the web browser remain in the caller and the called

As far as this WordPress blog’s 404.php role goes in all this, we were keen to maintain Venn Diagrams that were purely image based data, because the web browser sharing mechanisms are so much better this way, else we were tempted to just construct a webpage HTML dataset positioning text in an absolute way with a Venn Chart background image. In order to do these purely image based Venn Diagrams we used PHP’s GD image library as per …

So, moving on from Google Charts Image Chart Map Charts, today, let’s turn our attention to Google Charts Image Chart Venn Charts which we were dead set curious about given work we’d done in the past regarding Venn Diagrams, which we referenced when we presented Flowchart and Venn Diagram and Mind Map Token Subject Emoji Tutorial some time back. Gobsmackingly good is the Google approach, again, as you’d expect, but the approach covers different ground, so one feels one should go back to Primary School!

Python GraphViz via PHP on AlmaLinux Tutorial

Do you remember reading, with PHP Image GraphViz via Pear on AlmaLinux Primer Tutorial below, our outlining three known GraphViz guises …

the recent, alas now deprecated, Google Charts Image Charts GraphViz option means of drawing SVG graphics within an HTML image … we’ve known about before about yesterday …

today’s interest, that being PHP Image GraphViz via Pear on AlmaLinux install, via the AlmaLinux cPanel “Module Installers” Pear installer page, means by which we can use GraphViz calls in PHP code … and, for the future …

GraphViz installs for Python via pip

…? Well, today, we start down the road of …

installing Python GraphViz package via …
pip install graphviz
… then …
getting great help from https://graphviz.readthedocs.io/en/stable/, thanks, as the Python code basis we call subgraph_example.py … and …
used and remoulded by our overseeing PHP subgraph_example.php Python GraphViz using web application

… we need to work on more after this first draft start to another road of our GraphViz journey last talked about at PHP Image GraphViz via Pear on AlmaLinux Focus Tutorial.

PHP Image GraphViz via Pear on AlmaLinux Focus Tutorial

On non-mobile focus goes to the address bar on many web browsers unless there is a (nominally) visible input type=text or textarea next in line.

Why the non-mobile mention? Well, on mobile, a user programming [HTMLelement].focus(); call has no affect, as the touch operating systems need control of focus arrangements, presumably?!

How can we forget? My liege, please accept my humble apologies?!

So that’s that, and other progress today is to allow the emailing or SMS of a recalled URL Step arrangement via more options on that “Recall Dropdown” we started allowing for yesterday.

Please see this happening in our changed PHP coded My Recipe Steps web application you can also try below.

take a deep breath before starting intersessional window.localStorage work, as it is not to be sneezed at, as any sort of doddle (at least for us) … as well as …
since last intersessional window.localStorage work we’ve started using email and SMS sharing hashtagging arrangements that fit in, like a glove, with this intersessional window.localStorage work … so that …
even though, we write the code here in PHP, all this functionality is client based … which we like because …
get the idea correct, with careful forward planning and implementation, we’ll be able to apply similar such thinking into the future, whether that be for clientside only web applications and/or ones that call on serverside code (like PHP) … and …
if we can keep things just clientside more readers can be involved, we figure

hashtagging (where data limits are so much longer) can help it remain as a clientside only solution environment (rather than relying on some form method=POST to a serverside (eg. PHP) receiver solution) …
window.localStorage is a step up from the HTTP Cookie style of intersessional (personal) storage as far as amounts that can be stored is concerned

What are we aiming for here, then, with our improvements?

Graphviz (short for Graph Visualization Software) is a package of open-source tools initiated by AT&T Labs Research for drawing graphs (as in nodes and edges, not as in bar charts) specified in DOT language scripts having the file name extension “gv”. It also provides libraries for software applications to use the tools. Graphviz is free software licensed under the Eclipse Public License.

We really like HTML image maps, and it occurred to us with yesterday’s Google Chart Image Chart Image Map Tutorial we were hiding its light under some bushel somewhere, because …

yesterday we introduced with only the onclick event coded for in the HTML area subelements to the map parent element … linked to an …
associated img element … via an …
attribute called usemap … and two aspects, at the very least, to stuff under the bushel are …
1. many more events than onclick can be defined as you define the area subelements … and here’s the kicker …
2. you can add area subelement event logic that, on paper, would cause interference with other event logic (ie. the same event type in an event bubbling through scenario) but it won’t if you, as a programmer, turn that use of the usemap attribute on and off like a tap

… which, to our mind, represents the bee’s knees of event management. So useful!

To tip our toes into this woooorrrrrlllllddd we’ll show you some newly added area subelement event logics in a Google Chart Image Chart Radar Chart example below …

Both colour and degree counterclockwise angle became “Mantissa Madness Monday” tragics, a bit like moi, really?

How did we express these two measures?

colour can be derived at the 404.php end via mantissae that are 9 or more long where a number of the form rrrgggbbb is numerical and passed across to 404.php in the y co-ordinate mantissa … while … kind of crazily …
angle can be a set of zeros in the x co-ordinate mantissa represented by zero characters to the length of the angle from 1 to 359 in front of a pre-existant font size (in px) usage, from last “Mantissa Madness Monday” (us getting away with this because no font size should start with a zero)

… or, much more …
web browser Web Inspector debugging

… but with that second approach debugging the inhouse Nimh game, as first cab off the rank, we were thrown by scenarios that went …

we’ve isolated a URL (with arguments) for the Nimh game (and isolate it for issues) …
we type that into a web browser address bar …
we get a blank webpage … and so we open …
the web browser Web Inspector …
Console tab and see no errors … and then …
clicking for Elements tab we see empty “body” element with a non-empty “head” element

… and we were thrown at that stage, used to PHP errors manifesting themselves with that “body” element. We woke up after a few minutes, and opened up that “head” element, and down the bottom of that element (similarly to the “body” element debugging) there was the latest PHP error needing to be attended to. Yayyyyy!! Panic averted!

From there, lots to do, indeed, but the debugging has a controlled feeling about it, realizing this can happen. Eventually … Nimh (don’t be the last to take a match)!

AlmaLinux TimeZone Places Associative Array Tutorial

Have you been waiting for more “heads up” regarding issues we’ll have moving from a PHP (of a version starting with a 5) to a PHP (of a version starting with an 8)? Join the crowd?! But so far, it hasn’t been that bad. That is, until we started into looking at the PHP TimeZone functionalities. Going back to a previous time of referencing this, at the recent Google Charts Geo Chart Region Picker Conditional Positioning Tutorial, associative array based codelines like …

<?php
$ourtz=new DateTimeZone($zzbit); $ourtzgl=$ourtz->getLocation(); $versus=str_replace('"' . '' . '"];', '"' . $zzbit . '","' . '' . '"];', $versus); $yourgl=explode(',',('' . implode(',',$ourtzgl))); //$versus=str_replace('"' . ' ' . '"];', '"' . $ourtzgl[latitude] . '","' . ' ' . '"];', $versus); //$versus=str_replace('"' . ' ' . '"];', '"' . $ourtzgl[longitude] . '","' . ' ' . '"];', $versus); $versus=str_replace('"' . ' ' . '"];', '"' . $yourgl[1] . '","' . ' ' . '"];', $versus); $versus=str_replace('"' . ' ' . '"];', '"' . $yourgl[2] . '","' . ' ' . '"];', $versus);
?>

… worked and meant codelines avoiding associative array logic, in favour of numerically indexed array thinking, like above (thanks to implode) were not needed then, on CentOS, but are needed now, in a redesign, on AlmaLinux, in the changed TimeZone Places (the old way) (and TimeZone Places (the new way)) tz_places.php PHP code.

Google Charts Geo Chart Region Picker Alignment Tutorial

In our inhouse Region Picker we like the way the right hand webpage side involved some useful …

position: sticky;

… positioning, useful within the realms of what is going on on the right hand side.

But now we’re wanting some horizontal integration, linking commonalities of left and right regarding the country of interest, as a user’s eyes scan across the webpage, at pivotal times.

Our new Javascript functions to help, today, further to the recent Google Charts Geo Chart Region Picker Shading Tutorial …

… all feature the great [element].scrollIntoView() way to programmatically scroll, rather than use (the sometimes ignored) window.scrollTo([left],[top]); or location.href=’#[elementID]’; approaches. It has the advantage of not altering location.hash (if you see that as a plus). We’d rather not add complexity, so, yes, we prefer the [aCountryElement].scrollIntoView(); call approach, at those pivotal times. This accounts for the left hand side of the webpage agreeing to the right hand side’s vertical scroll position. But what about the other way around? There, we started applying a CSS padding-top property to relevant right hand side elements (via DOM [element].style.paddingTop=[pixelsToExtendDown]px;), at pivotal points in the programming flow.

And on double clicking a right hand side button to start creating those background Geo Chart SVG based “images” we turn on a progress cursor, at least for non-mobile platforms, because the user needs patience here, in the changed regions_via_countries.html Region Picker.

… with more success.

We can’t remember a “foreground overlay” scenario so resembling a “background image feeling” end result, the transparent colour introduced into the Google Charts Geo Chart SVG being crucial to help make this all work.

Today we’re working on more Google Charts Geo Chart inhouse web application interfacer functionality other web applications might be able to make use of … “tool” functionality, if you will.

We want to be able to control the way a Google Charts Geo Chart can be nested within an HTML div element, for instance. We started the day wanting to be able to make …

a Google Charts Geo Chart be a background image to a div element … alas, on this first draft we couldn’t get there (but will continue with the research here) … whereas we succeeded …

TimeZone Places Nearest Places Tweak Tutorial

When we presented GeoJson World Countries Drag and Drop Makeover Nuance Tutorial we tweaked our inhouse TimeZone Places PHP web application. But it needs a “re-tweak”.

In that Nearest Places form part of the TimeZone places webpage, we noticed that even when shaping to enter a TimeZone Placename in the first textbox we made no attempt to fill in …

latitude
longitude

… when we have the information to do so, and even if we’re misunderstanding a placename designation, that should not stop us from trying, because those two numerical fields above can be corrected, and the form resubmitted, in these scenarios.

Apart from making a PHP derived Javascript variable be made available to the code, we “wrap” …

<?php
$otherform="<br><br><iframe id=nearestif name=nearestif style=display:none; src=about:none></iframe><div id=nearest></div><form target=nearestif action=./tz_places.php method=GET style=background-color:#f0f0f0;>Place: <input onblur=\" if (this.value.length > 0) { document.getElementById('nearestif').src=perhapsfillin('./tz_places.php?latitude=&longitude=&place=' + encodeURIComponent(this.value)); } \" type=text id=nplace name=place value=></input> Latitude: <input type=number id=latitude name=latitude value=0.0000 max=90.0000 min=-90.0000 step=0.0001></input> Longitude: <input type=number id=longitude name=longitude value=0.0000 max=180.0000 min=-180.0000 step=0.0001></input><br><input style=background-color:orange; type=submit id=inearest value='Nearest TimeZone Places'></input></form>";
?>

GeoJson World Countries Drag and Drop Makeover Nuance Tutorial

Nuance alert! We’re not sure if you noticed, but if you tried out the Drag and Drop functionality in the World Countries web application of yesterday’s GeoJson World Countries Drag and Drop Makeover Tutorial you may have noticed …

for a country with lots of TimeZone places, like Brazil, you could get a decent Google Chart Geo Chart map up … but if you were to click the “Map?” link down the bottom of that iframe …
it would fail to show a Google Chart Map Chart for that country’s TimeZone places

This fix, believe it or not, is interesting, perhaps only in an “internal use only” sense, we grant you. But our solution got us delving even more into hashtagging data, so that the solution we came up with was a hybrid whereby …

stayed with PHP $_GET[] (ie. address bar ? and & argumented) data (versus using PHP $_POST[] methodologies) … but …
where it came to the &data=[most of the data] part, other than its first character, we hashtagged the rest

… so that the logic flows as per usual, but we intervene at places and flesh it out via location.hash (client side only) means. We won’t bore you too much with all the places of intervention except the receiving map.php’s “easiest to get” intervention …

At first …

we wanted the first popup window content be aligned to the top and left … and then …
we thought it would be good to also, in “Drag and Drop land”, relevant countries nearby to the user’s drop point TimeZone Places be showing below that (and it panned out the best way to show this, for us, was via an iframe pointing at another incarnation of the tz_places.php webpage, because it could have GET arguments iso, iso2, iso3 etcetera to point at ISO 2 letter country codes, which we made more readily available (via a new data-cc global data attribute applied to the select option subelements presented) for the changed external Javascript countries.js we decided should get into the mix via a new Javascript function …

the combination of Google Directions‘s talents allowing you to reposition on the fly … and …
the onmousemove event, at least for our non-mobile users

… could mean that if we pre-plot airports on the world map, given that the user has clicked the ✈ ( ✈ ) “Show an Interest in Airports” emoji button, as a non-mobile user hovers over the world map, this pre-plotting might help trip planners with their travel options, should air travel be part of their interest, in the same way it is an option up at Google Directions in our changed countries.php web application you can also try below. The overlay scenario now reads …

Onto yesterday’s GeoJson World Countries TimeZone Times Tutorial GeoJson World Countries web application’s capabilities we want to add zooming, that doesn’t rely on web browser functionality (which continues to work).

Some readers might be aware of our “theory regarding adverbs” and “web applications” on the net …

the most catered for adverb relates to the “where of life” … and the second banana is …
the “when of life”

… and, further to yesterday’s GeoJson World Countries SVG Overlay Safari Error Tutorial‘s emphasis on the “where of life”, today we add in a bit of the “when of life”, something right down the line of the remit of TimeZone talents.

Seriously though, a lot of us dream of the rest of the world on a world map, and wonder what time it is in other parts of the world. Phone call to relatives? A reminder SMS call? Email a game collaboration? It could all be part of life’s rich tapestry!

The expresion of this, for us, today, improving the communications with our current GeoJsom World Countries web application, take the form of emoji clocks from the 12 hour clock example forms such as …

1 o’clock is 🕐 🕐
2 o’clock is 🕑 🕑

A problem repeatedly occurred with https://www.rjmprogramming.com.au/HTMLCSS/countries.php

On discovering our first solution theory of turning yesterday’s mapsvg.js external Javascript work into an async piece of work made no difference to this situation, we surmised that the huge amount of content held in the Javascript (ie. client side) global variable appendtoinnerHTML was causing memory issues. We couldn’t shift much to do with the overall amount of “data” needing to be handled, in order to implement country SVG colour infilling, but we could shift the data from being …

What deducible data item needs to be determined for these Geo Charts to work?

Know your GeoJson! Yes, pretty obviously, any two GeoJson datasets might display the same in that “map plotting” sense, but one might have different and/or more “intelligence” than the other. Often, an XML has more “intelligence” than equivalent HTML (barring the use of global data attributes, that is), as today’s ~~Corolla~~corollary.

And so, moving on from yesterday’s GeoJson World Coastline TimeZone Tutorial, today, we present a new GeoJson admin 0 countries we download, and upload as “countries.geojson” data set, again via the excellent HTTP://geojson.xyz/ repository, thanks.

From it, we do get a different JSON additional “intelligence” …

neither will interrupt the mobile gestures associated with swiping and pinching, which refer to the events “ontouchstart” and “ontouchend” at either end of their lifespan

PHP Image GraphViz via Pear on AlmaLinux Focus Tutorial

Posted on September 28, 2024 by admin

PHP Image GraphViz via Pear on AlmaLinux Focus Tutorial

On non-mobile focus goes to the address bar on many web browsers unless there is a (nominally) visible input type=text or textarea next in line.

Why the non-mobile mention? Well, on mobile, a user programming [HTMLelement].focus(); call has no affect, as the touch operating systems need control of focus arrangements, presumably?!

How can we forget? My liege, please accept my humble apologies?!

So that’s that, and other progress today is to allow the emailing or SMS of a recalled URL Step arrangement via more options on that “Recall Dropdown” we started allowing for yesterday.

Please see this happening in our changed PHP coded My Recipe Steps web application you can also try below.

get the idea correct, with careful forward planning and implementation, we’ll be able to apply similar such thinking into the future, whether that be for clientside only web applications and/or ones that call on serverside code (like PHP) … and …
if we can keep things just clientside more readers can be involved, we figure

hashtagging (where data limits are so much longer) can help it remain as a clientside only solution environment (rather than relying on some form method=POST to a serverside (eg. PHP) receiver solution) …
window.localStorage is a step up from the HTTP Cookie style of intersessional (personal) storage as far as amounts that can be stored is concerned

Graphviz (short for Graph Visualization Software) is a package of open-source tools initiated by AT&T Labs Research for drawing graphs (as in nodes and edges, not as in bar charts) specified in DOT language scripts having the file name extension “gv”. It also provides libraries for software applications to use the tools. Graphviz is free software licensed under the Eclipse Public License.

PHP Image GraphViz via Pear on AlmaLinux Recallable Tutorial

PHP Image GraphViz via Pear on AlmaLinux Recallable Tutorial

After yesterday’s PHP Image GraphViz via Pear on AlmaLinux Sharing Tutorial some readers may be curious to understand the distinction between …

email and SMS sharing … and …
inhouse intersessional sharing via window.localStorage (ie. like HTTP Cookies)

… over yesterday’s and today’s blog posting timings. Simply put, for us, we …

take a deep breath before starting intersessional window.localStorage work, as it is not to be sneezed at, as any sort of doddle (at least for us) … as well as …
since last intersessional window.localStorage work we’ve started using email and SMS sharing hashtagging arrangements that fit in, like a glove, with this intersessional window.localStorage work … so that …
even though, we write the code here in PHP, all this functionality is client based … which we like because …
get the idea correct, with careful forward planning and implementation, we’ll be able to apply similar such thinking into the future, whether that be for clientside only web applications and/or ones that call on serverside code (like PHP) … and …
if we can keep things just clientside more readers can be involved, we figure

hashtagging (where data limits are so much longer) can help it remain as a clientside only solution environment (rather than relying on some form method=POST to a serverside (eg. PHP) receiver solution) …
window.localStorage is a step up from the HTTP Cookie style of intersessional (personal) storage as far as amounts that can be stored is concerned

What are we aiming for here, then, with our improvements?

extend the existant email and SMS functionality …

The term “GraphViz” …

Graphviz (short for Graph Visualization Software) is a package of open-source tools initiated by AT&T Labs Research for drawing graphs (as in nodes and edges, not as in bar charts) specified in DOT language scripts having the file name extension “gv”. It also provides libraries for software applications to use the tools. Graphviz is free software licensed under the Eclipse Public License.

angle can be a set of zeros in the x co-ordinate mantissa represented by zero characters to the length of the angle from 1 to 359 in front of a pre-existant font size (in px) usage, from last “Mantissa Madness Monday” (us getting away with this because no font size should start with a zero)

Graphviz (short for Graph Visualization Software) is a package of open-source tools initiated by AT&T Labs Research for drawing graphs (as in nodes and edges, not as in bar charts) specified in DOT language scripts having the file name extension “gv”. It also provides libraries for software applications to use the tools. Graphviz is free software licensed under the Eclipse Public License.

2. you can add area subelement event logic that, on paper, would cause interference with other event logic (ie. the same event type in an event bubbling through scenario) but it won’t if you, as a programmer, turn that use of the usemap attribute on and off like a tap

… which, to our mind, represents the bee’s knees of event management. So useful!

yesterday we introduced with only the onclick event coded for in the HTML area subelements to the map parent element … linked to an …

1. many more events than onclick can be defined as you define the area subelements … and here’s the kicker …
2. you can add area subelement event logic that, on paper, would cause interference with other event logic (ie. the same event type in an event bubbling through scenario) but it won’t if you, as a programmer, turn that use of the usemap attribute on and off like a tap

… which, to our mind, represents the bee’s knees of event management. So useful!

To tip our toes into this woooorrrrrlllllddd we’ll show you some newly added area subelement event logics in a Google Chart Image Chart Radar Chart example below …

Both colour and degree counterclockwise angle became “Mantissa Madness Monday” tragics, a bit like moi, really?

How did we express these two measures?

angle can be a set of zeros in the x co-ordinate mantissa represented by zero characters to the length of the angle from 1 to 359 in front of a pre-existant font size (in px) usage, from last “Mantissa Madness Monday” (us getting away with this because no font size should start with a zero)
