The coffers of Unix hold many simple tools, which by themselves are powerful, but when chained together facilitate complex data manipulations. Unix's use of functional composition eliminates much of the tedious boilerplate of I/0 and text parsing found in scripting languages. This design creates a simple and succinct interface for manipulating data and a foundation upon which custom tools can be built. Although languages like R and Python are invaluable for data analysis, I find Unix to be superior in many scenarios for quick and simple data cleaning, idea prototyping, and understanding data. This post is about how I use Unix for EDA. read | learn | pipe | rule!

Compared to any of the popular tablets—the various iPads, the Nexus 7, Amazon's range—the Surface Pro is absurdly overpriced and its battery life is pathetic. Compared to an Ultrabook, it's not that bad: a little ahead in some ways, a little behind in others. The thing is, in spite of its pricing, the Surface Pro isn't an Ultrabook.... This makes Surface Pro an awkward sale. Surface RT was difficult to categorize, and Surface Pro, if anything, exacerbates that difficulty.

Here are some technologies that have such strong "street cred", they are effectively untouchable. Anyone who dares imply that they are deficient in any way is instantly labelled an uneducated moron. It is impossible to have a realistic conversation about these technologies, and it's not very common for enthusiasts of these technologies to admit their failings. Why your pet technology sucks.

Clearly Linux isn't the best operating system, because OpenVMS is. And any lack of drivers for OpenVMS is a benefit, not a shortcoming.

In a world first, on 3 December 1992, an engineer sent the message "Merry Christmas" from a PC to a mobile device using Vodafone's UK network. But the origins of the idea date back further to Matti Makkonen. Over a pizza at a telecoms conference in 1984, the former Finnish civil servant put forward the idea of a mobile phone messaging service. This was to become the SMS (short message service) standard. An interview, 140 characters (or less) at a time.

Many of the broad family of specifications commonly grouped under the “HTML5” umbrella are scheduled to be completed in 2013, and with the release of Internet Explorer 10, the users of every major web browser flavor can enjoy rich Web apps written on the open web platform, with no need for plugins. Lots of people are excited about HTML5, but one group I don’t see as particularly excited are security experts, or perhaps they’re only excited in a rather cynical fashion. Full employment! Browser botnets! A lifetime of conference talks! HTML5 is a key part in one of the greatest security success stories in the history of computing.

Competition in automotive technology has long been about who’s got the most horsepower, the best towing capacity or the fastest acceleration. These days, though, it’s all about having the slickest infotainment systems and most-connected cars. The shift in focus from what’s under the hood to what’s behind the dashboard has brought a largely covert war to the auto industry over the operating systems that will control these gadgets. As in the smartphone biz, the battle line is between proprietary and open source software. The outcome will determine what these systems look like, how they work and how distinctive they are as automakers embrace walled gardens or open ecosystems. It looks like you're driving a car. Would you like help?

The original Arduino IDE is great for beginners, but it lacks a lot of features that advanced users need. And I've tried a lot of other solutions. But all were based on plugins and hacks to other IDEs, which lead to not-so-good performance. For example, a very famous plugin provided access to terminal console by adding a fixed option to the IDE Tools menu. So, if you're working with two different boards, you have to change this hard-coded option every-time.... Windows only. Surely someone appreciates this.

IDisposable is a standard interface in the .NET framework that facilitates the deterministic release of unmanaged resources.... Despite IDisposable having only a single method named Dispose to implement, it is commonly implemented incorrectly. After reading this blog post it should be clear how and when to implement IDisposable, as well as how to ensure that resources are properly disposed when bad things happen (also knows as exceptions). To dispose() or not to dispose(); that is the question.

The... “multiple layers of defense” strategy applies to modern software development. For example, even though the compiler will scream at you if your code does not make sense, there is no reason to skip fixing it, if you happen to see it on your editor.... The principles are summarized as: If you screw up, you want to know earlier than later, and the first layer should have the lowest cost and effort. Test early, test often... and get something to test automatically if you can.

Although there exist numerous books explaining principles and structures of operating systems, there is a lack of descriptions of systems actually implemented and used. We wished not only to give advice on how a system might be built, but to demonstrate how one was built. Program listings therefore play a key role in this text, because they alone contain the ultimate explanations... Built from scratch to teach system design with actual, working code.

Like most developers (I assume), I spend the majority of my workspace staring at a terminal window.... When you look at your terminal this much, it needs to be beautiful. More than that, it needs to know you. You need to have a history with it. No, not like that. Here are 5 things that you can do to make your terminal great. ...and it will love you bash.

If he's assuming most devs are penguins, the only type for whom that assumption is reasonable, why should I assume anything else he has to say is relevant either?
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?

Do you like Unix? Do you really like Unix? Well, what if I told you there's a little-known operating system out there that's more Unix than even Unix is. Cool, right? Well it is true! Plan 9 occupies an interesting niche in the open source operating system world. It is a full-fledged descendant of Unix, but not in the way that most systems out there are. It took the bones and beating heart of Unix and then built a brand-new cybernetic exoskeleton around it, with lasers, and heat vision... oh wait. You want to boot this bad-boy up, right? Well, okay, we'll do that. But what hardware shall we run it on? Hey, you got a Raspberry Pi? Thanks to 9fans, there's a ready-to-go image for the Raspberry Pi.

Can digital rights management technology stop the unauthorized spread of copyrighted content? Ten years ago this month, four engineers argued that it can't, forever changing how the world thinks about piracy. Their paper, "The Darknet and the Future of Content Distribution" was presented at a security conference in Washington, DC, on November 18, 2002. ...and how they nearly got fired for it.

Ask yourself, how on earth can an IDE that requires 7.56 GB to install be fast enough to even be usable at all? What kind of monster machine is required to not even choke to death when I accidentally open a second instance of Visual Studio? We’ve all seen those dreadful white screens of death, right? SharpDevelop seems happy with just 64 Mb. Is that a feature or a bug?

On Nov. 29, 1972, a crude table-tennis arcade game in a garish orange cabinet was delivered to bars and pizza parlors around California, and a multi-billion-dollar industry was born. Here's how that happened, direct from the freaks and geeks who invented a culture and paved the way for today's tech moguls. Game Just Getting Started.

Building apps that behave like humans is hard. Building ones that see the world and interpret it like we do is even harder – it’s because of this that developers at Google, Microsoft and many other large companies have invested so heavily in projects like reCAPTCHA so that they can try and teach computers to read the way humans do..... This is where OCR software comes in, and more directly for us developers, OCR software that offers an easy to use API for plugging your app into its 20/20 vision. Building an OCR-capable app the easy way.

This is the first (zeroth) post in a series on getting started using MonoGame to create a Windows 8 Store game. Unless you want to spend the money on a Unity3D license, I think it’s the best option available for a hobbyist C# game developer to create a game for Windows 8. Interesting series of posts on Windows 8 game development. Follow along.

I’ve been a little late to the NuGet bandwagon. Overall I am really happy with the service that NuGet provides. It is not all smooth sailing though.... TFS get latest on a solution does not bring down NuGet package changes. I did have an idea about how to at least raise the awareness of new and updated NuGet packages in a solution to a team that uses TFS. Using the new Team Alerts feature in TFS 2012 will do the job. A custom TFS alert can notify the developers of a check in to the packages directory.
