There's a secret for Perl being so good at code golf, and this secret is clever use of regexp. The regexps from Posix are just finite automata, but the Perl engine is much more powerful than that. Naturally, I became tempted to check what are the computational limits of Perl's regexp. For example, can we do arithmetic with regexps? After thinking I while, I concluded that yes, we can do arithmetic with regexps! When a problem arises, some think "I know, I'll use regex." Now you have a quadratic equation.

Now you have 2 problems the one you started with and regex.

You would probably have 3 problems. The third problem would be maintaining the will to live.

Python is about to get an Enum. And it's sad. It's not awful. It just fails to do anything particularly well - it's an awkward compromise whose only real achievement is not doing anything new. What would you expect a Pythonic enum to look like?

Spear phising is an extremely potent hacking vector that combines social engineering with phishing. Basically, an attacker tries to learn enough about a specific victim to inform the design of a fake email that the victim is more likely to think is legitimate and thus open and engage with.... Over the last several months, I have been the target of what might be a new, more scalable, approach to spear phishing. I have been receiving phishing emails that are sent using the names of people I know but not their email addresses... This is real and it's dangerous. Be careful out there, folks.

I've seen this sort of thing years ago when an acquaintance had his/her pc/email account compromised and the spammer send spam to everyone in the address-book claiming to be from another randomly selected name in it. Unless I'm overlooking something there isn't anything new here.
Did you ever see history portrayed as an old man with a wise brow and pulseless heart, waging all things in the balance of reason?
Is not rather the genius of history like an eternal, imploring maiden, full of fire, with a burning heart and flaming soul, humanly warm and humanly beautiful?

Same idea, slightly more sophisticated implementation. From what I've read about it, you'd get an email from someone you know about something you might discuss. Much more social engineering effort.

I was explaining on Hacker News why Windows fell behind Linux in terms of operating system kernel performance and innovation. And out of nowhere an anonymous Microsoft developer who contributes to the Windows NT kernel wrote a fantastic and honest response acknowledging this problem and explaining its cause. His post has been deleted! Why the censorship? I am reposting it here. This is too insightful to be lost. New features help much more at review time than improvements to old ones.

On August 31, 2012, Japanese mathematician Shinichi Mochizuki posted four papers on the Internet. The titles were inscrutable. The volume was daunting: 512 pages in total. The claim was audacious: he said he had proved the ABC Conjecture, a famed, beguilingly simple number theory problem that had stumped mathematicians for decades. Then Mochizuki walked away. He did not send his work to the Annals of Mathematics. Nor did he leave a message on any of the online forums frequented by mathematicians around the world. He just posted the papers, and waited. A B C. It's easy as 1 2 3. As simple as...

The funny thing is that within a few months of our launch, several competitors emerged and they all had crawlers. But, from our users’s perspective, we were more advanced since we had categorization which was definitely no easily automated task. We didn’t actually build a real crawler for the first 9 months and just kept scaling manually by hiring more data entry professionals. Instead, we were able to focus our resources on improving the product and user acquisition. It’s now clear to me that not building that crawling technology early on was one of the reasons our startup succeeded. Sometimes failing to automate gives you a clearer view of how automation should work later.

Yes, Update 3 is likely the last of the updates to the VS 2012 line. Of course, we'll still continue to fix any critical issues people find but we are winding it down and focusing on VS V.Next. I'd like to think many of the issues you refer to will get addressed there and, if not, I hope we'll get to them in the V.Next update train. Referring to the above - Update 3 is the update where we slow down the churn, address remaining high impact customer issues and any regressions introduced in Update 2. Insider thinking about bug fixes, updates and moving forward with Visual Studio.

Following the cupholder principle, GPUs began to evolve to allow easier to access APIs from more common programming languages becoming General Purpose GPU or GPGPUs. Several systems researchers at Georgia Tech and elsewhere are now redesigning chip layouts to make the best most efficient uses of CPUs and GPGPUs. The theory community hasn't seem to catch on yet. There should be some nice theoretical model that captures the vector and other operations of a GPGPU and then we should search for algorithms that make the best use of the hardware. How are you using GPU processing in your code?

As a fair warning to the reader, these primers are a bit more terse than what you’d find in your average textbook. I only introduce the bare minimum required to understand the main content posts, so there are carefully chosen gaps whose exclusion is necessary for time’s sake. If the reader is confused about something, or wants a deeper explanation of a concept we deliberately leave out, feel free to leave a comment asking about it and we will do our best to fill in the gaps. My initial reaction was big-O notation.

Unveiled in 2005, Arduino boards don't have the CPU horsepower of a Raspberry Pi. They don't run a full PC operating system either. Arduino isn't obsolete, though—in fact, its plethora of connectivity options makes it the better choice for many electronics projects.... Last December, we featured 10 of the most amazing Raspberry Pi projects, including arcade cabinets, robotics, and a wearable computer. This one goes to 11—as in, we'll show you 11 awesome things hackers and electronics enthusiasts have created with the Arduino. What have you built with Arduino?

After discovering that at least one account had been compromised, we sent a company-wide email to change email passwords immediately. The attacker used their access to a different, undiscovered compromised account to send a duplicate email which included a link to the phishing page disguised as a password-reset link. This dupe email was not sent to any member of the tech or IT teams, so it went undetected. This third and final phishing attack compromised at least 2 more accounts. One of these accounts was used to continue owning our Twitter account. This is not a joke. Repeat: this is not a joke. If this were a joke you would be advised to...

Microsoft, which already has a stake in Barnes & Noble’s Nook and college bookstore businesses, is offering to buy them outright for $1 billion, according to a report in TechCrunch, based on leaked internal documents. The documents also reportedly say that Barnes & Noble plans to discontinue its line of Nook tablets by the end of fiscal year 2014, while letting the e-readers stick around for awhile longer. A nook can’t read so a nook can’t cook, SO... a Surface with Nook might be a good hook.

On May 9, we invite you to participate in Global Accessibility Awareness Day (GAAD). The purpose of the day is to get people talking, thinking and learning about digital (web, software, mobile, etc.) accessibility and users with different disabilities. The target audience of GAAD is the design, development, usability, and related communities who build, shape, fund and influence technology and its use. While people may be interested in the topic of making technology accessible and usable by persons with disabilities, the reality is that they often do not know how or where to start. Take an hour out of your day to experience digital accessibility first-hand.
