"I was really excited to write this article, because it gave me an excuse to really think about what beautiful code is. I still don't think I know, and maybe it's entirely subjective. I do think the two biggest things, for me at least, are stylistic indenting and maximum const-ness. A lot of the stylistic choices are definitely my personal preferences, and I'm sure other programmers will have different opinions. I think the choice of what style to use is up to whoever has to read and write the code, but I certainly think it's something worth thinking about. I would suggest everyone look at the Doom 3 source code because I think it exemplifies beautiful code, as a complete package: from system design down to how to tab space the characters." John Carmack himself replies in the comments.

Hi,
Where I draw the line is over-engineered regex:
* they can be completely unreadable - even to many seasoned developers
* and they usually run slower then multiple, more precise, expressions.
* they can be completely unreadable - even to many seasoned developers
* and they usually run slower then multiple, more precise, expressions.
The other problem is adequate error handling.
For me, adequate error handling means telling the user what was wrong with descriptive error messages; like "missing space between foo and bar", "bad character after foo", "bar needs to be at least 4 characters", etc.
With a single over-engineered regex the only error message you can do is "Something was wrong but this code is too stupid to tell you what"...

A basic example is a 'trim' command. The following will remove spaces from the start and the end of the string:
s/(^\s|\s$)//
However it's actually computationally less efficient then having two separate replaces:
s/^\s//
s/\s$//
On the other hand, why not have a goddamn Trim function? It's infinitely more readable than any of this 's/' crap. You're trying to make excuses for a write-only language who's code looks like line noise by saying, 'Well, a good programmer should be able to read line noise'

The third and final WWDC product I want to talk about is - of course - OS X 10.9 Mavericks. While iOS 7 was clearly the focus of this year's WWDC, its venerable desktop counterpart certainly wasn't left behind. Apple announced OS X 10.9 Mavericks, the first OS X release not to carry the name of a big cat.

We already talked about iOS 7 yesterday (after a night of sleep, it's only looking worse and worse - look at this, for Fiona's sake!), so now it's time to talk about the downright stunning and belly flutters-inducing new Mac Pro. As former owner and huge, huge, huge fan of the PowerMac G4 Cube - I haven't been this excited about an Apple product since, well, I would say the iMac G4. This is the Apple I used to love.

Apple held its big keynote event thing at WWDC earlier this evening, but since I was away with friends I've had to read up on it later in the evening. The company announced iOS 7, OS X 10.9 Mavericks, and they gave a preview of the new Mac Pro. Especially the Mac Pro impressed me, and while iOS 7's new Holo/Metro-inspired theme looks messy and garish to me, I do commend Apple for finally breaking the mold. This news item will focus on iOS 7 - I'll dive into the Mac Pro and OS X 10.9 tomorrow (it's late here now).

And yes, the PRISM scandal is far, far from over. More and more information keeps leaking out, and the more gets out, the worse it gets. The companies involved have sent out official statements - often by mouth of their CEOs - and what's interesting is that not only are these official statements eerily similar to each other, using the same terms clearly designed by lawyers, they also directly contradict new reports from The New York Times. So, who is lying?

This story is getting bigger and bigger. Even though most Americans probably already knew, it is now official: the United States government, through its National Security Agency, is collecting the communications and data of all American citizens, and of non-Americans using American services, through a wide collaboration with the large companies in technology, like Apple, Google, Microsoft, Facebook, and so on. Interestingly enough, the NSA itself, as well as the US government, have repeatedly and firmly denied this massive spying on Americans and non-Americans took place at all.

Ah, patents - the never-ending scourge of the technology industry. Whether wielded by companies who don't actually make any products, or large corporations who abuse them because they can't compete in the market place or because they're simply jerks, they do the industry a huge disservice and are simply plain dangerous. According to The Wall Street Journal (circumvention link), president Obama is about to take several executive actions to address patent trolls - which may seem like a good idea, but I am very worried that all this will do is strengthen the positions of notorious patent system abusers such as Apple and Microsoft.

With version 13.05, the developers of the Genode OS Framework take measures to ensure that Genode continues to scale well with a growing number of users and the steadily broadening platform coverage. Further highlights are the improved SoC support for Exynos 5, OMAP4, Raspberry Pi, i.MX, and new components for realizing headless systems.

At the D11 conference, Apple CEO Tim Cook once again took the stage to be interviewed by Walt Mossberg and Kara Swisher. While most of the interview can be replicated by picking and reading 10 random Apple fanblog stories - there were still a number of very interesting things that warrant some closer scrutiny.

So, the Xbox One disaster continues. Microsoft's policy for dealing with the used games market has reportedly leaked - and it's a clear and direct attack to destroy the used games market. Prices for used games will be set at the retail value of a new game, and retailers have to hook into Microsoft's computer systems and comply with Microsoft's terms and conditions.

At an event earlier today, Microsoft unveiled the next Xbox - the third model, but confusingly named Xbox One. The big focus was TV, integrated Kinect, and all the other stuff we all expected to be forced down our throats. I think it took them 25 minutes to actually come to what should be the core of the story: gaming. Nothing groundbreaking in the gaming department, except for how Microsoft intends to handle the used games market and borrowing games from friends: pay up, buddy!More Features »

But again, this is all down to experience. A good Perl developer should be able to read that code easily enough.
Where I draw the line is over-engineered regex:
* they can be completely unreadable - even to many seasoned developers
* and they usually run slower then multiple, more precise, expressions.
A basic example is a 'trim' command. The following will remove spaces from the start and the end of the string:

However it's actually computationally less efficient then having two separate replaces:

So the real issue isn't Perl's syntax, it's that you're either reading bad Perl code, or that you're not familiar enough with Perl to understand it's syntax.
And this is my problem with people who bang on about how bad Perl / C++ / etc is for readability vs Python / VB / etc. Those people are generally inexperienced developers and thus not really qualified to comment. It's a bit like saying simplified Chinese is less readable than English, because I'm an English speaker who's only exposure to Chinese is from friends of that heritage.
