Web images, HTML and high DPI displays – or, how do you develop, write HTML, for “retina” displays, displays with more than the usual 72 dots per inch (DPI)? Images on mobile device displays sometimes look blurry. That’s because smartphone displays are, for example on a Samsung Galaxy, 360 pixels wide – but, here’s the […]
Recently, I did some development of a webapp which was using threejs for display of geometry in a WebGL view. The prototype worked great when I decided to move it into a cordova based webapp, to remove the need for a webserver, and make it self-contained, it stopped working. The surprise: what was working in […]
Wer möchte kann seine Webcam abkleben – das kann helfen, wenn man unter Paranoia leidet und sicher sein möchte, dass auch kein Flash Plugin oder anderer Software Fehler ermöglicht, dass jemand über das Internet auf die eigene Webcam zugreift und heimlich mitschaut, was man macht… Also, Post-It raus, zuschneiden und fertig:
With apple-touch-icon vs. apple-touch-icon-precomposed, the difference is that apple-touch-icon is a square bland rendition of your logo or icon, without any shadows, rounded corners or glass effect applied – iOS will do that for you, in case it want to (looking at you iOS 7) – while apple-touch-icon-precomposed is the icon just as it will […]
In one sentence: Make sure you have “third party cookies” enabled/allowed in your browser settings! I can’t stress this more, I lost hours of bug hunting until I finally thought of this setting, which was the root of my problem. It was this Mozilla bug report which directed me into the right direction. It tells […]
I’ve encountered a strange error when I bundled a well-working Userscript with Scriptify into a Firefox Extension: The summary: this is not a Scriptify issue! The verbose explanation: My userscript was using the @require marker to use jQuery and it’s matching engine to do some of it’s magic. Problem was – as soon as my […]
Just in case you haven’t noticed: upon install, Scriptify will add a bookmark to your browser, pointing to the internal docs at: scriptify://locale/help/main.xhtml (Welcome to Scriptify)
Userscript are a great way to add functionality to your browser. And many people have Greasemonkey installed. But if you want to reach people without GM installed with your script, you need to wrap it up as a real, native, full-blown Browser Add-On, for example a Firefox extension, an .xpi file. The BabelExt framework, once […]
Embedding Video natively into HTML is a dream come true, finally, with HTML5. But the video tag has it’s own quirks. While Firefox mostly asks for ogg/theora video+audio and “just works”, serving the right video to Apple+Safari users and Opera, IE, etc on all sorts of hardware/devices. give new headaches – well, currently. (Fingers crossed […]
When it comes to life-logging, I’ve already outlined how important it is from my point of view to make it *reasonably*. Even the CEO of Memoto, reminds us to keep it easy, so we don’t invest more time in logging than in living. And that’s important from the maker of a camera that takes pictures […]
Got that?! (In case you want to do one of these really creative timeline cover images…)
Life logging. Yes, I know. Some people tend to overdo it, but hey, there’s an interesting concept here – easily capturing what you did, when, where and what you feel about it, if it was a good experience or a bad one, musings, etc. Most people using facebook kind of do it already. But there […]
Today, after I moved the database around on MySQL for one of my WordPress installs, I was suddenly greeted with this error after logging in: “You do not have sufficient permissions to access this page.“ Following some of the guidance on the Codex’ Login Trouble page brought no resolution, some even felt simple-minded, like deactivating […]

As a privacy concerned person you might walk away from Google as your primary search engine. You just don’t feel comfortable about how they store or keep your searching habits? You have switched to Linux as you regard it as more stable, more secure and more streamlined than other OSs? You promote the open-source movement […]

Although this was only a temporary problem, wikimedia was down – due to a database connection error, see…
Email is as old as the internet, but it needed Google to make it fun? Come on! I can’t believe this. There is no real Gmail rival, not even a Gmail clone! The thing people like the most about gmail seems to be the ability to dynamically sort and search emails in an advanced way, […]
