In a presentation, I would like to create a Twitter Timeline with a few selected tweets. In the best case it should look as natural as if someone went to Twitter on his own computer or saw it on his smartphone.
I am using LateX Beamer for the rest of the slides, but I am flexible if it is another software that allows to export a PDF/Image that I could include in LateX.
(There are a lot of tools on how to integrate live Tweets in PowerPoint / Keynote , but I want to do it for historical tweets and will be offline during the presentation.)
I was trying the following:
- Simply take screenshots of the tweet and arrange them within LateX or PowerPoint. Looks ok but not super nice, and quite cumbersome to do.
Since it is possible to extract an html of a tweet to embed on a homepage, I thought of doing this for the presentation. Unfortunately, I don't know much of html / reveal.js presentations.
Has anybody found a good solution for a similar problem?
EDIT:
I started reveal.js and found the following plugin: https://github.com/rajgoel/reveal.js-plugins/tree/master/embed-tweet
I was then trying to apply it and followed the intros to reveal.js and also saved the source code of the plugin into my plugin folder for reveal.js. However, it does not work (=Returning a blank page in the html). Can anybody point me to my error? (I am completely new to reveal.js / html so sorry if it is basic?)

From what I know, the browser can only request the assets (JS, CSS) after parsing the HTML. But analyzing the "Performance" tab on Edge's DevTools, the "Send Request" for the w3schools30.css stylesheet happens before the parsing is even started, as we can see indicated by the green arrow and other data in this image.
I'm using a simple example. Here's index.html:
<!DOCTYPE html>
<html>
<head>
<link rel="stylesheet" href="https://www.w3schools.com/lib/w3schools30.css"/>
</head>
<body>
Performance testing
<script src="index.js"></script>
</body>
</html>
And the index.js:
setTimeout(() => {}, 1000)
Am I misunderstanding the timeline or there is a circunstance where this happens?
I think it is related with a feature called "preload scanner" on Chromium browsers. This article says:
A preload scanner's role is speculative, meaning that it examines raw
markup in order to find resources to opportunistically fetch before
the primary HTML parser would otherwise discover them.
i have a pdf form that i need to be able to import as a background then use Dompdf to overlay html/text.
can this be done?
thanks
Dompdf is a library for converting HTML -> PDF. I'm no expert on that particular library but as far as I can tell it doesn't do things like overlaying html/text.
PDF cannot be imported into HTML because it isn't an HTML format and it isn't an image. There might be a parser library somewhere (e.g. http://www.pdfonline.com/easyconverter/sdk/pdf-to-html/), but without your own fairly extensive work you wont get that PDF document to be displayed in HTML.
HOWEVER, you CAN use something like this, it'll show your PDF document as the background, create a div that covers the screen just above the PDF document to make it non-interactive, then you can put all your contents above that. Note that there will be controls showing on the sides which as far as I know can't be prevented since they're provided by the browser when displaying a PDF file (you could use some fancy JS/CSS to prevent it I'm guessing but I don't know exactly how off the top of my head).
<!DOCTYPE html>
<html>
<head>
<meta charset="utf-8">
<title>PDF as background</title>
</head>
<body>
<iframe src="http://unec.edu.az/application/uploads/2014/12/pdf-sample.pdf" style="width: 100vw; height: 100vh;position:absolute;top:0;z-index:0;"></iframe>
<div style="position:fixed;width:100%;height:100%;z-index:1"></div>
<div id="content" style="position: absolute;top:50%;left: calc(50% - 4cm);z-index:2">
<h1 style="font-size:20px;background:#00ff00;">I am on top of the PDF document!</h1>

We have a browser-based solution that we want to integrate with Datalogic scanners.
We will be using the locked down browser as our primary interface.
We've got as far as configuring the scanner and can confirm that it is decoding our Code 39 barcodes.
We've set up a test page that is supposed to take the scanned code and dump it in a text area.
The test page is
<!doctype html>
<html>
<head>
<meta charset="utf-8">
<title>TEST</title>
<meta http-equiv="DL_Code_39" content="Enable">
<meta http-equiv="DL_Scan" content="Javascript:ValidateInput()">
<script language="javascript" type="text/javascript">
function ValidateInput(n){
document.getElementById("sku").value+=";"+n;
};
</script>
</head>
<body>
<form method="post" name="fTest">
<textarea rows="5" cols="15" name="sku" id="sku"></textarea><br>
<input type="submit" value="go">
</form>
</body>
</html>
When we scan, the javascript call is firing, but returning undefined.
If we give the javascript function call a variable (something not done in the documentation) it does not fire
We must be missing something simple but there is no sample code in the DL documentation and google can find nothing else either.
Any help would be greatly appreciated.
I have always found javascript support to be flaky on Windows CE. I assume this is what the data logic scanner is running on?
I would normally configure the scanner to act as a keyboard, that way you can use standard html forms and handle the logic server side. I haven't got a Scorpio to test with but the Falcons have this ability under encoding options.
You can also set a prefix and suffix that the scanner will append to the scanned barcode. In your case it looks like this might be ';\n'
I have solved this on my own
The problem in this case is one of the reasons why developers drink too much.
The problem is the name of the example javascript function described in the documentation
This code works perfectly
<!doctype html>
<html>
<head>
<meta charset="utf-8">
<title>TEST</title>
<meta http-equiv="DL_Triggers" content="Enable">
<meta http-equiv="DL_Code_39" content="Enable">
<meta http-equiv="DL_Scan" content="Javascript:PassSKU">
<script type="text/javascript">
function PassSKU(n){
if (n === undefined) {
n = 0;
}
document.getElementById("sku").value+=";"+n;
};
</script>
</head>
<body>
<form method="post" name="fTest">
<textarea rows="5" cols="20" name="sku" id="sku"></textarea><br>
<input type="submit" value="go">
</form>
</body>
</html>
The only thing I changed was to rename my function call from ValidateInput() (the function name given in the documentation which I copied and pasted) to PassSKU
So
<meta http-equiv="DL_Scan" content="Javascript:ValidateInput">
This does not work
<meta http-equiv="DL_Scan" content="Javascript:AnyOtherFunctionName">
This works fine
WHY this fixed the problem is a topic for another time.
In case someone comes across this question while searching for information on getting a Datalogic scanner to work with a web form, I've posted a working solution here: stackoverflow: "Datalogic Falcon X3 - Barcode Scanner"
I'm evaluating brunch build system for my needs. I need to make simple HTML preprocessing. So basically I need to produce several files with common headers and footers:
file1.html:
<html>
<head>
<title>Title1</title>
</head>
<body>
<div id="content">
<div id="header">...</div>
Page1
<div id="footer">...</div>
</div>
</body>
</html>
file2.html:
<html>
<head>
<title>Title2</title>
</head>
<body>
<div id="content">
<div id="header">...</div>
Page2
<div id="footer">...</div>
</div>
</body>
</html>
So either a simple include functionality or (preferrable) some kind of extends functionality. Ideally syntax should hide in comments so my IDE won't complain about non-HTML characters. I liked preprocess javascript library, but that's not necessary, of course.
Unfortunately I didn't find anything suited for that task in brunch. There's support for many HTML template engines, but they seem to generate JS functions. I need simple static HTML as a result, not JavaScript SPA.
I'm not certain there's any built-in solution to this yet, but if I was to go in the direction of HTML templates / partials, I'd look into either "after-brunch" and "before-brunch" plugins on NPM.
I don't know what's your program-language of choice for FileSystem manipulation (read, merge, write, etc.), but in theory you could use something like "before-brunch" to execute a batch / shellscript / or command of somekind to collect your HTML partials together into your file1.html, file2.html, ... before Brunch compiles and copies it to the public/ folder.
In case you're familiar with Haxe, here's a Gist that I shared a while ago. It's a post-process script to merge other files on specific lines of documents.
https://gist.github.com/bigp/90e38deeccc94145b033
Here's what an HTML document could look like:
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<title>DEMO</title>
<link rel="icon" href="data:;base64,=">
<style id="css" type="text/css" rel="stylesheet">
/* #MacroMerge: public/app.css */ //<--- Merges All CSS here..
</style>
</head>
<body>
<script type="text/javascript">
/* #MacroMerge: public/vendor.js, public/app.js */ //<--- And all JS here..
</script>
</body>
</html>
EDIT:
Almost forgot, here's how the brunch-config.coffee script would use the Haxe script with the after-brunch plugin:
plugins:
afterBrunch: [
"haxe -cp . --macro MacroMerge.html('app/index.template.html','public/index.html')"
]
Come to think of it... nothing stops you from taking this example and specifying HTML partials (or any file extension really, ex: *.txt, *.xml) wherever you need them. Again, might only be useful to you if you're familiar with Haxe. If not, it's open-sourced & free to download (http://haxe.org/download/).
I am trying to put processing sketches with multiple .pde files(tabs or classes) on my website, but it does not seem to be working. You should be able to click and make balls appear that bounce around the screen. However, it does not seem to be registering that there is a second .pde file, and therefore, the sketch does not work fully.

A regular one file sketch works fine, I think it has something to do with the fact that this sketch has a ball.pde class for the balls that are supposed to appear.
Figured it out, it was as simple as typing the other .pde file you wanted to load after the one you chose like so (with a space):
<canvas class="project" data-processing-sources="ball/Ballbounces.pde ball/Ball.pde" ></canvas>
