SEARCH KEYWORD -- Case sensitivity
Buffcacher
What should a ‘cache’ be? It means a lot of things, but to my mind the default programming type should be: “keep around expensive-to-generate bits of read-only data in case we need them again, or until the computer really needs that RAM for something else†I was writing a custom video editing program in Python (interesting choice of language for that problem) and I wanted to cache decoded frames; but I just wasn’t happy with the memory management of explici...

An experience on fixing HTTP 406 Not Acceptable error
This post is about an experience of mine on fixing a HTTP 406 Not Acceptable error seen on one of my page. Just got back from a business trip and opened my computer as usual to start to monitor my website statistics. But when I opened the page on showing real time page views, it shows nothing but zero. So I pressed F12 to bring up the developer tool to check on what's going on. The logic of loading the real time page view is backed by AJAX call. In the developer tool console, I see that the rAJA...

Full disk encryption is too good, says US intelligence agency
You might be shocked to learn this, but when a quivering-lipped Chloe from 24 cracks the encryption on a terrorist’s hard drive in 30 seconds, the TV show is faking it. “So what? It’s just a TV show.†Well, yes, but it turns out that real federal intelligence agencies, like the FBI, CIA, and NSA, also have a problem cracking encrypted hard disks — and according to a new research paper, this is a serious risk to national security.The study...

How to check whether a web page can be loaded in iframe
Sometimes you may want to load other website's page in your own website's iframe, but due to some security concerns, other website may have security configurations which prevent you from loading their pages into your iframe. In this case, if you try to load them, you would see a blank page or a text message telling that it's prohibited. Fortunately, you can detect this before you actually decide to load it. To prevent a page from being loaded by an iframe from other site, the response ...

Sustainability
When I was in business school 25 years ago, I don't recall the term sustainability used. Maybe it was, but it certainly didn't register in my brain. The mantras that I recall were return on investment, shareholder value, revenue growth, and driving efficiencies in the business.But as I look at many of the challenges facing businesses today, it seems to me that the focus on performance and efficiency often comes at the cost of sustainability. This talk by Clay Christensen really drives that point...

A New Experimental Feature: scoped stylesheets
Chromium recently implemented a new feature from HTML5: scoped stylesheets, aka. <style scoped>. A web author can limit style rules to only apply to a part of a page by setting the ‘scoped’ attribute on a <style> element that is the direct child of the root element of the subtree you want the styles to be applied to. This limits the styles to affect just the element that is the parent of the <style> element and all of its descendants. Example Here’s a...
Want to write some code? Get away from your computer!
I’ve recently realised something. The best place to write code isn’t in front of your computer, with your compiler, IDE and tools. The best place to write code is far, far away from any of these tools – somewhere where you can think properly. For a language with which you are fairly familiar, the mechanics of translating the program in your mind to a program that the compiler can compile (or the interpreter can interpret) is fairly easy – it’s coming ...
User experience : Exception handling
Exception handling is the process of handling emergencies or unpredictable operational errors. The specific time of the occurrence of unexpected events and the actual consequences of the specific situation are difficult to predict. How to handle this unexpected crisis is also related to the user experience of your users. Let's first look at how some famous products deal with unexpected exception encountered by users:1. Goodyear tires can automatically expand when leaking.Tire blast is one of the...
