What? You think just anyone can type '<' and '>'. That takes a professional!

They're not really skills; more a list of languages and technologies that someone thinks might be in demand by employers. A few of them go together; for instance a web developer would need to know a reasonable mix of some of the items on the list to be able to get a job. Silly, really; single language skills are very limiting and just because you know n languages doesn't mean you're going to be any good at creating something useful with them.

At previous jobs, they have asked me if I have "XML experience".
Having written XSLT user controls (and transforms for XML config files), SOAP web services, AJAX in various incarnations (with usually zero exposure to actual XML), HTML (and DOM composition/traversal, which is a bit like virtual XML), web.config files and other XML formats, yet calling XML a skill still has pretty much no meaning to me. It's like listing "Text" as a skill. It's just a basic file format (or a data format, as sometimes it's not actually stored in files); I doubt those asking for the skill know anything about it beyond the buzzwords (e.g., "semantic", "human readable", "web friendly", and so on).

Definitely agree with you, but remember where this came from; it's driven off of job ads posted. We all know who is most likely to write those posts. So, I think your last line:
AspDotNetDev wrote: I doubt those asking for the skill know anything about it beyond the buzzwords (e.g., "semantic", "human readable", "web friendly", and so on).
is completely accurate. I'm surprised that "must own car" wasn't on the list of programming skills.

A number of years ago I showed an example of creating a typical digital clock using picture numbers and a little bit of VB.NET code. Fast forward to today and I have decided to show you an example of creating an analog style clock in VB.NET 2012.... If you are new to programming, and how to draw things on a Panel, this little sample code can get you started. So let's get to the project! Retro clock. Retro code.

Timothy Jordan gave developers at SXSW a sneak peek at the Google Mirror API, which is what they'll use to build services for Glass, and now you can see it as a video. What it reveals is that the Mirror API has more structure than you might expect. Everyone seems to be as much frightened by Google Glass as they are excited by it, but what of the ways in which we can program it? Surely it is going to be complicated interacting with all that sophisticated design - speech input, speech output, the gesture based UI and so on. Where to start? Any real work that your app performs has to be done on the server.

My love for programming languages is very much akin (and I swear linked to the same part of my brain) as my love for human languages: they are all unique and beautiful in their own way. I love Python, I love C, I love Smalltalk, I love Erlang, etc, etc. But Perl has taken an entirely undeserved beating in recent years, and so, in karmic balance, it deserves a round of outspoken championship, far more than others need right now. In pondering why Perl’s current reputation is so completely disjointed from the reality of the language, I’ve boiled it down to three “Big Bang Theory”-esque ideas: “The Cookie Slap! Effect”, “The Awkward Adolescence Fallacy”, and “The Singularity Paradox”. People still use Perl because it still works and the community has evolved with the language.

While at Waza this year, I had a chance to talk to my friend Guillaume Roques. In addition to talking about SalesForce, we took advantage of our mutual .NET backgrounds to discuss Microsoft. We did the typically uncompromising praise of The Gu and how far Azure has come along in the last 18 months… and of course we had to talk databases. Below is my quick little list of reasons I gave him as to why I’m favoring Postgres over SQL Server from a technical/business aspect. Is the table half-full or half-empty?

A UNIX programmer was working in the cubicle farms. As she saw Master Git traveling down the path, she ran to meet him. “It is an honor to meet you, Master Git!” she said. “I have been studying the UNIX way of designing programs that each do one thing well. Surely I can learn much from you.” “Surely,” replied Master Git.... Upon seeing this, the novice was enlightened.

Last week, web developer Francois Remy published an initial analysis of Internet Explorer 11 -- the next version of IE that surfaced via a leaked copy of Windows "Blue". In his analysis, he noted that he found references to various WebGL APIs but ultimately wrote them off as non-functional. Picking up where Remy left off, I dug a little deeper and discovered WebGL support is indeed incomplete but is coming and can be enabled for experimentation. Tired of WebKit wrangling? Teach IE11 some new tricks.

I beleive the frustation is with the fact that Win 8 does such a lousy job for desktop environments (and laptop), and now people have to deal with it. The fact the Microsoft has apparently sold few Win 8 copies to the existing windows base seems to indicate that they have not succeeeded in replacing the traditional OS. Of course Vista was never real successful, but Windows 7 was. I expect, again, that Microsoft will have to wait until the next version of windows before it produces an OS that people will want to replace thier Windows 7 OS, and I suspected this would be true before it was released with what I heard about it..

I think it's common knowledge MS make a beyond terrible OS so that they can sell more of the one they make after it.

Struts 1, the venerable Java MVC Web framework, has reached End Of Life status, the Apache foundation has announced. In a sense, the move simply formalises what has already happened, as the Struts team have focused their efforts on version 2; the last release of Struts 1 was version 1.3.10 in December 2008. The change of status does mean however that, whilst the code and documentation will still be available, no further security patches or bug fixes will be issued. Once the 'Killer App' for J2EE, Struts is now effectively dead.

There is a lot of hate for “touch” out there and I thought I’d talk about it a bit. I can tell when I’m reading an unreasonable discussion because there is always something about having to stand there all day with your arms stretched out to touch the screen. I stop reading when this is mentioned. Why would anyone stand there with their arms stretched out constantly? Microsoft certainly doesn’t require this, so anyone who makes that comment just isn’t paying attention. Or rather, is just trying to be difficult. My frustration with Windows 8 on most of the PCs I use is that they don’t have touch.

In his presentation at Breaking Development in Orlando FL Rod Farmer outlined some of the challenges you're likely to encounter when making the transition to designing for TV. Here's my notes from his talk on Context, multi-device and the future of TV in the browser. TV as a device is dead. TV as entertainment is very much alive.

I am the most happy when I’m challenged which is twisted because I also doubt my abilities the most when I’m challenged because with challenges comes failures. I’m a competitive person. I see people writing code or having deep knowledge in subjects I don’t understand, so I ask questions, and more questions, until people are probably blue in the face.... Bigger apps, faster code, new languages and frameworks... there's always something new for coders.

No one wants to think of themselves as a Luddite, which is part of what makes technological conservatism so insidious. It can color the thinking of the nerdiest among us, even as we use the latest hardware and software and keep up with all the important tech news. The certainty of our own tech savvy can blind us to future possibilities and lead us to reject anything that deviates from the status quo. We are not immune. When I was a kid we coded in vim, and we liked it... Oh, wait...

Have you ever wondered how PCI cards are able to perform basic operations — such as accessing a disk, displaying graphics, or booting off the network — before their drivers have been loaded? Or why cards are platform specific, despite the fact that everyone is using standardized PCI interfaces? The answer actually lies on the card itself, inside a bit of addressable flash memory called the “Option ROM”, which contains executable code that’s located and run at boot time.... This leads me to my small Friday evening project in getting a PC version of the Radeon 7000 64MB working on a PCI Power Macintosh, for which no 64MB cards were released. Hardware not compatible? Nothing a little soldering can't solve...

If you're reading this page, chances are that you're already well aware that E.T. for the Atari 2600 is one of the most reviled games ever made. I never understood why. As a child, it was one of my favorite games. I still think it's a good game. Apparently, I'm not alone. On this page I'm going to briefly explore why people hate E.T., and how the game can be fixed.... It turns out that E.T. isn't a bad game after all. With a few simple changes we were able to dramatically improve an already good game by eliminating the most common complaints. Just grab the ROM, open a hex editor and start playing...

Bit level manipulation allows us to write more efficient code due to the fact that CPU's are really good at handling bits. In fact that's all they really do. Even if you've never played around with bit manipulation it's likely that your compiler has modified your code to use bit manipulation. Slide to the left. Now slide to the right...

Shifting right by 1 isn't actually the same as dividing by 2.. rounds the other way for negative numbers.
Anyway, no offense, but that wasn't very interesting. There are many interesting bit level manipulations, but that blog post shows none of them - the ones it does show are exactly the sort of thing a compiler does automatically.
Here are a few more interesting (IMO) examples:
- (x - 1) & x removes the lowest set bit. Very useful, for example to iterate over a sparse set of bits without having to test them all, or to test whether a number is "a power of 2 or zero".
- x & -x sort of the dual of the previous one; isolates the lowest set bit.
- (x + 1) | x an other kind of dual of the first thing - sets the lowest zero. Useful to iterate over dense sets of bits.
- mask = value >> 31; return (value + mask) ^ mask; computes the absolute value of a 32-bit integer without branching.

Those are really useful, you should publish or at least point us to where you sourced them if they're not yours.
