When Bush was in charge and the senate was Republican, why didn't the Democrats filibuster all their stupid laws they got through? Or is it because they think filibustering is lame so they won't repay with the same coin? If so, then the Republicans will own the system no matter what.
Self-aggrandizing much? Since there has been books with SQL injection vulnerabilities in their examples, Open Source projects with provably skilled programmers containing these flaws, it is not only utter imbeciles that do not protect against these types of attacks. Or maybe they are just complete idiots in comparison to your God-like skillz. That kind of narcissism makes it hard to actually improve technology and processes. Your solution to SQL injection is "dont be an idiot" while a more pragmatic and humble programmer would solve the problem by using an ORM layer which obviates the need to perform manual SQL string interpolation so that SQL injections can not occur. It is about thinking out of the box, not that everyone around you are idiots. Which you learn, sometimes, with experience.
The same kind of "soft skills" is what is making it impossible for most of us to ever become CEO:s, board members of corporations or ever landing a job within the ruling class. If having lots of social network friends is a proxy for soft skills, then surely being on first name basis with Donald Trump is a proxy for management skills. For some reason children of actors and artists are much more likely than regular people to also become actors and artists. Is it because the ability to act is genetic or because their parents were "linked in" with the right people?
Linkedin should be that better process. Sadly people give out recommendations like confetti. I've worked with a sociopath and a lazy slimeball ( two people ) who both got good recommendations on there.
People are corrupt. They value their friends above the common man and will give them a free pass no matter what. When Joe recommends his good friend Mike, who he knows is a shitty developer, it is the same form of corruption as when politicians accept bribes. It is very unfair to those who are not "linked in."
The device is an EEG reader, it does not read facial expressions! I don't understand why the submitter had to mention facial expressions just to confuse poor slashdotters. Anyway the applications you can develop with a consumer priced and accurate real-time EEG reader is boundless. Marketers could use it to find out what commercials are the funniest, all psychology programs at all universities could use it for limitless amount of experiments, you could use it for your porn collection or music collection to automatically and passively get a rating for which porn/music you think is best. If you are one of those persons who send links to "funny" videos to your "friends" you could have the EEG reader app do it automatically for you when you watch a video that is funny enough.
If this gadget is as cool as it looks, it is definitely what I will get for Christmans. Though I'm fairly sure it will suffer the exact same problems early accelerometers did with to low resolution and to much noise to be useful as input devices.
Since when? You might say it is unethical or even immoral, but illegal? From the other side? Sure. Political parties, candidates or elected officials have to disclose their contributions and expenditures, but I have never heard of a law requiring bloggers to disclose anything. Should they? Sure, but unless you can point out a law that requires them to do so, I call bullshit.
It is called tax evasion which is illegal last I checked.
Bribing bloggers is illegal. It is illegal for bloggers to accept compensation from political parties without disclosing it. Everyone is not doing it, unless you can find evidence that everyone is doing it. If there is evidence that one party is doing it, but no evidence that the other party is doing it, then that party is the only party that should be shunned for doing something highly immoral. If that party happens to be the party you like, you could try to improve that party by complaining to your party officials. On the other hand, claiming that the other side is doing the same thing, without any evidence, as an excuse for the side you like, just makes you look childish imo.
Please explain what features Direct3D lack that exists in OpenGL? D3D 11 offers hardware tesselation, compute shaders and much more. Those features will take ages before they will show up in OpenGL. And when they show up, they will likely show up as extensions, meaning that you won't be able to rely on the feature being there as the manufacturer may not have implemented that particular extension.
Wouldn't packet segmentation mean that the firewall has to reconstruct the whole tcp stream to know which http pages are being accessed? Plus, facebook has hundreds of IP's each users profile page can be accessed under at least a handful of different paths:/userprofile/profile.php?uid=123 and so on. Maybe not impossible, but it seem unrealistic to me. I'm not an expert at all though.
Regarding your examples, OpenGL, SDL and OpenAL, they are all stone age technologies compared to what Windows offer in DirectX.
Oh noes! They work fine. OpenGL is only a whisker behind Direct3D and it's years ahead in other ways, like actual usability. Or so say all the game developers I've talked to about it, the plural of anecdote is not data though.
You are an idiot. Direct3D 11 was released in July 2009, and there are already games using it. Its counterpart, OpenGL 4 was released in March 2010 almost a year later. And it will be a very long time before any cards will implement it anyway.
And maybe you should ask your game developer friends if SDL, OpenAL and OpenGL is "all they need..."
OpenAL has very spotty support among sound card manufacturers
On Linux, it backends to ALSA or pulse (maybe OSS too.) On Windows, it will fall back to stereo where OpenAL is not available.
At which point you lose the only feature OpenAL brings to the table; 3D sound. What you are left with is a really crappy sound API that nobody likes.
SDL is a very fast library and is amazing when it comes to blitting 2d graphics. The only problem is that games with 2d graphics aren't very popular anymore.
SDL does a lot more than graphics. Fail, fail.
I never stated that SDL *only* does graphics you illiterate retard. But that is the only thing it does really well. If you are looking for a networking, sound mixing, font rendering or image loading api, you are better off using something else than SDL.

SDL is a very fast library and is amazing when it comes to blitting 2d graphics. The only problem is that games with 2d graphics aren't very popular anymore. OpenGL is a good standard to have, but it evolves much slower than DirectX so it trails behind and can't take advantage of the latest features gpu:s provide. Fortunately wine does a fairly good job implementing the DirectX API and it is always improving. I don't mind as a Linux user that I have to run wine to play most games.
I'm curious about that aspect too... Blocking only specific web pages would require very sophisticated deep packet inspection much more advanced than China's firewall for example. The filter would have to replace responses to only certain paths on a domain with 404 html pages or 302 redirects to other pages that explain why the original page can not be viewed. It would be wholly impractical to block a whole nation the size of South Korea in this way.
No you are wrong. RTFA you idiot. Assange is arrested for "på sannolika skäl misstänkt" which is the highest suspicion level and allows the prosecution to keep the suspect incarcerated the longest.
The other aspect is that he has been arrested for "probable cause." In Sweden, you can be arrested in two ways, either only "arrested" or "arrested for probable cause." In the second case, it means that the prosecutor is fairly certain you will be convicted of the crime in court. So it appears, based on the extremely few details available, that the rape accusations are not entirely baseless.
I think that fixing the X server - one mitigation is to disable the MIT-SHM extension as discussed in the pdf - really reduces the exposure but since the real problem is in the kernel, it doesn't completely remove the threat.
The shm extension is integral to all modern xorg servers. You *may* be able to run xorg without shm, but many programs will refuse to work and performance will drop to a few percent of what it is with shm enabled. It's the transport the X server uses for communication with its client. With shm (shared memory) disabled, it has to serialize all objects and send them over a socket which of course is dog slow.

If you start selecting tags to make the output look the way you want it to look, you don't understand XML (and subsequently shouldn't be using DocBook).
Anyone who was some experience writing documentation knows that the main objective is to write beautiful and readable documentation, not choosing the right markup...
The fact that you couldn't find the tag but could find the other tags you've mentioned is just depressing, especially when those tags are most often sub-tags of a code tag block.
The CODE tag is new in DocBook 4.3. Version of jade shipped with Ubuntu 9.10 is 1.2.1 and it does not know about the CODE tag. That's another problem with DocBook, it is a moving target with a standard that moves faster than the tools that support it.
Just wait until you need to generate HTML help, Text file documentation, a web page manual, and a printed PDF of the same core documentation. The single-source design of DocBook will be much better appreciated then, if you learn how to use it.
I doubt most people who express that belief has actually tried to publish the same documentation in HTML and PDF form. DocBook produces PDF by first converting the document to LaTeX (so one is left wondering, why not use LaTeX itself in the first place?) and then use its tools to export to PDF. The result is a document as ugly and badly type-setted as an O'Reilly book. The HTML output basically looks like a raw data dump of the text, like this book for example. That's underwhelming to say the least, considering that 50%+ of a DocBook document is spent writing XML markup.
If you really want to know why DocBook sucks so much, you should check out Sphinx which is a document writing system done right. For some reason, it can manage without the overly verbose XML and idiotic semantic markup and still produce high quality documents that blow DocBook's out of the water.

DocBook is probably the absolutely worst document writing format I have ever had the displeasure of working with. It seems to have been born in some deranged xml-lovers wet dream in which "documents" are "self-documenting," semantic structure is more important than content and structure is kept separate from presentation. You know all those generally good ideas that become very dangerous when taken to far, which DocBook exemplifies. The more xml the better, seem to have been their guiding principle. In HTML, P is the tag for paragraphs, not so in DocBook, guess P wasn't descriptive enough so it had to be PARA instead. In HTML, to create a preformatted block you often use PRE. Well obviously that was to simple for DocBook so you have to nest two tags INFORMALEXAMPLE PROGRAMLISTING source code/PROGRAMLISTING/INFORMALEXAMPLE.
Maybe you are asking, who the hell came up with the INFORMALEXAMPLE tag? Well in DocBook you can not just say "give me a block with fixed-width font" you have to be "semantic" because you must separate presentation from structure. This is the reason why the maintainers of the DocBook standard has to continuously invent new tags for use cases they didn't think of. For example, there are all these tags for describing different programming language identifiers: KEYWORD, FUNCTION, CLASSNAME, STRUCTNAME, TOKEN, PROPERTY, TYPE.. etc. They all make it so the word within the tags are formatted using italic text. But what if the programming language you are writing about in the text has a different concept not covered by DocBooks standardized tags? Then you're out of luck. You either cheat and use a different tag which happen to produce the same presentational italicized text you wan't or you submit an enhancement proposal to DocBook and wait for them to standardize your new tag. If you choose the former, you quickly realize that your carefully marked up DocBook text is nothing more than glorified HTML, with retardedly verbose tag names, in the latter case you will never complete your documentation because there will always be tags you'll need that you can't have.
Storing and fetching data through database interfaces is vastly more difficult than just using the standard input/ouput or plain text files. I've written hundreds of programs for processing experimental data and I can tell you: nothing beats plain old ASCII text files!
Well I believe utf-8 encoded text files beats them hands down. Especially for scientific research.//snarky
I know nothing about cars so I can't give you a car analogy, sorry. However, javascript performance isn't very important at all unless "the page" really is a full javascript application ala gmail. The reason for that is that you delay the javascript execution until after the whole page has rendered by hooking up your code with the body onload event. This avoid the page lockups you can encounter on badly coded pages where the browser can't render the page before the javascript has been run to completion.
Of course, the above is only true if all the javascript on the page follows best practices. That is seldom true if the page includes javascript from ad networks which has the bad habit of running document.write calls during the loading of the page. Since document.write can modify anything on the page, when such a function call is executed, the browser has to stop everything else until the javascript is run and then continue rendering. In that scenario, faster javascript execution would definitely lead to much faster page loads.
Yes, finally PulseAudio doesn't *add* an problems when I install it. On the other hand it doesn't provide any features I didn't already have over bare ALSA. When it comes to playing music, Linux is almost at the "just works" stage. However, recording is another chapter altogether..
PulseAudio doesn't have a gui for setting the audio input devices (that works) so you still have to muck around with alsamixer and/etc/asound.conf. Furthermore, you can't set the mic gain so recording with professional microphones means the sound becomes useless low. And there is no interpolation of the input sound which means the quality is much worse than in windows where the sound system performs smoothing. I tried doing some recordings as lately as a few months ago on a Dell laptop. Even asked in the #pulseaudio irc channel for advice. The helpful people there had no idea, except that my sound driver might be faulty. Going back to purse ALSA solved it.
Agreed. I have the apple.slashdot.org section turned off because I'm tired of pure slashvertisements for Apple products so why the hell do that kind of garbage have to infiltrate the rest of slashdot.
Stop repeating that lie. The copy protection on the PS3 has not been broken. The internet is full of examples of DRM protected video that is not broken either.
You enumerate only two of three concievable groups of customers; those that buy games because piracy is a hassle (you) or do it out of the kindness of their hearts. According to the article, only 10% of all those who aquired the game are like that.
The second group are those who pirate the games because they have no money. They are a large part of the games audience. The third group are those who have money, would have bought it but preferred to warez it instead. Those two groups together are 90% of the games market. If the game had strong DRM, so that you could not pirate it, people in the third group would be enticed to buy the game. Assuming as little as 10% are in the third group, using DRM would almost double the number of sales the game makes.
Ergo: it makes perfect sense for game publishers to use DRM.
