APL was referred to as a "write-only" language, meaning you could write a program but could not read and understand it!
However, I do remember one commercial application (ERP-like, LOB) written in APL and offered on a time-sharing service. Unfortunately, I cannot recall its name.

While the original Ruby script took maybe 2 hours to write, my straight port to C++ took more than 10! Most of this time was spent navigating the API of libjpeg, fumbling with pointers and buffer arithmetic, and hunting down type casting errors that subtly caused inaccurate results. However, check out the speed gains... That’s a speed up of more than 50x. And ten years worth of gray hair.

To be fair, the guy is a Ruby programmer. It would probably take me a similar amount of pain to re-write a piece of C++ code in Ruby.

libjpeg is a c library, not c++. The title should have been "Rewriting in C for Fun, Speed and Masochism"

But he said he was writing in C++. Using a C library from C++ still counts as "rewriting in C++" in my world, but perhaps our views differ.

Just read the article:
"When given the right amount of abstraction - in this case, a fast C++ library - writing the code to be adequately fast was trivial. Using old-school C-style library integration, on the other hand, ended with me wasting hours making little to no progress. "

So? That still doesn't mean he was rewriting anything in C.
|

Really? Do you understand english?
Using old-school *C-style* library integration, on the other hand, ended with me wasting hours

Do you?
ed welch wrote: <layer>*C-style* library integration
Means exactly that. It does not necessarily imply he rewrote the whole thing in C. In fact he probably didn't, if that's what he had done he would have said "I also tried to rewrite it in C, but that turned out to be a waste of time". Or something like that. It is far more likely he actually meant what he wrote, and he used C-style library integration into C++, which is a perfectly valid thing to do.

For a developer like me, font rendering is very important since, I always work with code, read stuff and do many things with letters most of the time. Ubuntu renders font really good and it’s ubuntu font is really cool. After installing Windows fonts, It looks really cool on the web too. For me Mac’s font rendering looks so weired mostly on the Web. I copied windows fonts to the fonts folder as I did in Ubuntu but still no luck. The A B C that I see.

The problems with JavaScript come from premature standardization. The language’s author Brendan Eich said: "I had to be done in ten days or something worse than JS would have happened." For a programming language designed in 10 days, he did an amazing job. Maybe he did too good a job: his first draft was good enough to use, and so he never got a chance to fix the language’s flaws. The opposite of JavaScript may be Perl 6. In the works for 12 years and still loved even less than JavaScript.

Did you know that you can run ReSharper Code Inspections on the server using TeamCity? In fact, we added support for this functionality in TeamCity just over a year ago but it seems that the feature is not widely known, specially by ReSharper users. The setup itself is extremely simple, and we’re going to walk through it, and additionally add some more goodies in the mix. You can check for code duplication, too.

For those of us who have been Windows Phone fans for a long time, we know what it’s like to watch a major release go awry. Well, quite frankly, it’s pretty much all we’ve seen. We’ve grown used to a total lack of noise from its inception and even simple mistakes like launching the flagship Lumia 900 on Easter. Just so many missed opportunities but with the release of Windows Phone 8, Microsoft is doubling down on the strategy of bungling major rollouts. Let’s just look at where things are in the US market. What do you think of Windows Phone 8?

In preparation for taking on Intel in servers and storage ARM has developed a new networking technology for its chips that lets them reach higher core counts than before while being able to effectively pass information across the chip. Up next: datacenter on a chip.

Linear algebra gives you mini-spreadsheets for your math equations. We can take a table of data (a matrix) and create updated tables from the original. It’s the power of a spreadsheet written as an equation. Here’s the linear algebra introduction I wish I had, with a real-world stock market example. Matrixes, determinants, eigen something something...

Microsoft's Surface tablets are more than just an experiment. They're the first sign of a radical pivot for Microsoft, away from software licensing and toward one big ecosystem of hardware and services. In an annual letter to shareholders, Microsoft CEO Steve Ballmer hinted at major changes for the company, saying that there is a “fundamental shift underway in our business and the areas of technology that we believe will drive the greatest opportunity in the future.” Seems like they've been making great mice, keyboards and consoles for years.

A back door installed in networking hardware could be very difficult to detect, says Schneider. "If you siphon off lots [of data], then someone who was looking would notice," he says. But "if it's a small scale, it would be pretty hard to tell." That's because part of the Internet is designed to be fault-tolerant and allow the occasional piece of data to go missing. "It would be hard to distinguish between drops and retries and something nefarious..." Is your router spying on you?

Big Data is currently in an identity crisis, just like The Cloud a few years back. People understand the gist of Big Data (unlike The Cloud where the name doesn't even tell you what the heck it is), but there isn't really a pervasive well-rounded definition of it yet.

I recently interviewed for a Big Data consulting job. The Java/Hadoop ecosystem is well-established. There are commercial distributions of Apache Hadoop with support, available from multiple companies. Microsoft was trying to develop their own Hadoop clone, but they recently gave up and are trying to integrate Hadoop into their server ecosystem. If you can't beat 'em, join 'em.

As developers begin to explore building audio applications in the browser, we are beginning to see more and more interesting demos. Pedalboard.js is no exception. It is a framework for building guitar pedalboard effects in the browser, including both UI widgets like pots and switches, as well as the audio effects themselves and the routing between them. The demo allows you to play with a number of prebuilt effects and apply them to various prerecorded samples, as well as live audio input from your microphone if you’re running Chrome Canary. This library goes to 11.

Creating a robot that could be beaten up for 4 hours and still work proved to be an interesting problem. After doing some research on different configurations and styles, it was decided we should leverage a prior project to get a jump start to meet the deadline. We repurposed sections of our Kinect drivable lounge chair, Jellybean! This was an advantage because it contained many known items, such as the motors, motor controllers, and chassis material. Additionally, it was strong and fast, it was modular, and the code to drive it was already written. You knocked my block off!
