Job Postings For Python, NoSQL, Apache Hadoop Way Up This Year 52

Nerval's Lobster writes: "Dice [note: our corporate overlord] collects a ton of data from job postings. Its latest findings? The number of jobs posted for NoSQL experts has risen 54 percent year-over-year, ahead of postings for professionals skilled in so-called 'Big Data' (up 46 percent), Apache Hadoop (43 percent), and Python (16 percent). Employers are also seeking those with expertise in Software-as-a-Service platforms, to the tune of 20 percent more job postings over the past twelve months; in a similar vein, postings for tech professionals with some cloud experience have leapt 27 percent in the same period. Nothing earth-shattering here, but it's perhaps interesting to note that, for all the hype surrounding some of these things, there's actually significant demand behind them."

Ask Slashdot: Beginner To Intermediate Programming Projects? 172

An anonymous reader writes "I've been teaching myself to code recently. I've made good progress so far, and I've written a bunch of little scripts to make my life easier. Here's the problem: most project ideas I come up with now either seem pretty easy or pretty impossible. I'm having trouble thinking of a project that'll stretch my skills without overloading them. I've tried finding open source projects to read through, but I run into the same thing: either it's straight-forward, or it requires reading a half-dozen dependencies, each of which has dependencies of their own. Anyone have suggestions on some intermediate-skill projects to undertake? Or some project files in an online repo that go beyond the basics without getting overwhelming? My language of choice is Python, but other languages are welcome."

GNU Mailman 3 Enters Beta 57

GNU Mailman, likely the most popular mailing list manager in use today, has finally announced the release of a beta for version 3. GNU Mailman 3.0 is a major rewrite, features include a central server with a REST API replacing the dozen or two programs that manipulated Mailman data directly, a shiny new web fron end (Postorius), and a new archiver (HyperKitty). Fedora is already using the new archiver and interface, which is quite a bit more modern looking than Mailman 2.x's interface (wayback machine link for posterity). Individual message thread views are greatly improved, and you can even reply from the web by logging in with your list credentials. If you'd like to try it out, see the announcement message.

Monty Python To Bid Farewell In a Simulcast Show 86

dacarr writes "The five remaining members of Monty Python will be performing in the O2 Arena, and their last show as a comedy troupe will be simulcast across hundreds of theaters in the UK, and roughly 1,500 more across the world, according to the Guardian. Michael Palin says this is really going to be the last time before the Pythons cease to be. Well, at least, before Monty Python, as a comedy troupe, runs down the curtain and joins the bleedin' choir invisible."

How 'DevOps' Is Killing the Developer 226

An anonymous reader writes "Python guru Jeff Knupp writes about his frustration with the so-called 'DevOps' movement, an effort to blend development jobs with operations positions. It's an artifact of startup culture, and while it might make sense when you only have a few employees and a focus on simply getting it running rather than getting it running right, Knupp feels it has no place in bigger, more established companies. He says, 'Somewhere along the way, however, we tricked ourselves into thinking that because, at any one time, a start-up developer had to take on different roles he or she should actually be all those things at once. If such people even existed, "full-stack" developers still wouldn't be used as they should. Rather than temporarily taking on a single role for a short period of time, then transitioning into the next role, they are meant to be performing all the roles, all the time. And here's what really sucks: most good developers can almost pull this off.' Knupp adds, 'The effect of all of this is to destroy the role of "developer" and replace it with a sort of "technology utility-player". Every developer I know got into programming because they actually enjoyed doing it (at one point). You do a disservice to everyone involved when you force your brightest people to take on additional roles.'"

Princeton Students Develop Open Source Voice Control Platform For Any Device 34

rjmarvin (3001897) writes "Two Princeton computer science students have created an open source platform for developing voice-controlled applications that are always on. Created by Shubhro Saha and Charlie Marsh, Jasper runs on the Raspberry Pi under Raspbian, using a collection of open source libraries to make up a development platform for building voice-controlled applications. Marsh and Saha demonstrate Jasper's capability to perform Internet searches, update social media, and control music players such as Spotify. You need a few easily obtainable bits of hardware (a USB microphone, wifi dongle or ethernet, and speakers). The whole thing is powered by CMU Sphinx (which /. covered the open sourcing of back in 2000). Jasper provides Python modules (under the MIT license) for recognizing phrases and taking action, or speaking when events occur. There doesn't seem to be anything tying it to the Raspberry Pi either, so you could likely run it on an HTPC for always-on voice control of your media center.

NYU Group Says Its Scheme Makes Cracking Individual Passwords Impossible 277

An anonymous reader writes "Researchers at New York University have devised a new scheme called PolyPassHash for storing password hash data so that passwords cannot be individually cracked by an attacker. Instead of a password hash being stored directly in the database, the information is used to encode a share in a Shamir Secret Store (technical details PDF). This means that a password cannot be validated without recovering a threshold of shares, thus an attacker must crack groups of passwords together. The solution is fast, easy to implement (with C and Python implementations available), requires no changes to clients, and makes a huge difference in practice. To put the security difference into perspective, three random 6 character passwords that are stored using standard salted secure hashes can be cracked by a laptop in an hour. With a PolyPassHash store, it would take every computer on the planet longer to crack these passwords than the universe is estimated to exist. With this new technique, HoneyWords, and hardware solutions all available, does an organization have any excuse if their password database is disclosed and user passwords are cracked?."

Ask Slashdot: Can an Old Programmer Learn New Tricks? 306

An anonymous reader writes "I have been programming in some fashion, for the last 18 years. I got my first job programming 15 years ago and have advanced my career programming, leading programmers and bringing my technical skill sets into operations and other areas of the business where problems can be solved with logical solutions. I learned to program on the Internet in the 90s.. scouring information where ever I could and reading the code others wrote. I learned to program in a very simple fashion, write a script and work your way to the desired outcome in a straight forward logical way. If I needed to save or reuse code, I created include files with functions. I could program my way through any problem, with limited bugs, but I never learned to use a framework or write modular, DRY code. Flash forward to today, there are hundreds of frameworks and thousands of online tutorials, but I just can't seem to take the tutorials and grasp the concepts and utilize them in a practical manner. Am I just too old and too set in my ways to learn something new? Does anyone have any recommendations for tutorials or books that could help a 'hacker' like me? Also, I originally learned to program in Perl, but moved onto C and eventually PHP and Python."

Glyphy: High Quality Glyph Rendering Using OpenGL ES2 Shaders 59

Recently presented at Linuxconf.au was Glyphy, a text renderer implemented using OpenGL ES2 shaders. Current OpenGL applications rasterize text on the CPU using Freetype or a similar library, uploading glyphs to the GPU as textures. This inherently limits quality and flexibility (e.g. rotation, perspective transforms, etc. cause the font hinting to become incorrect and you cannot perform subpixel antialiasing). Glyphy, on the other hand, uploads typeface vectors to the GPU and renders text in real time, performing perspective correct antialiasing. The presentation can be watched or downloaded on Vimeo. The slide sources are in Python, and I generated a PDF of the slides (warning: 15M due to embedded images). Source code is at Google Code (including a demo application), under the Apache License.

Regex Golf, xkcd, and Peter Norvig 172

mikejuk writes "A recent xkcd strip has started some deep academic thinking. When AI expert Peter Norvig gets involved you know the algorithms are going to fly. Code Golf is a reasonably well known sport of trying to write an algorithm in the shortest possible code. Regex Golf is similar, but in general the aim is to create a regular expression that accepts the strings in one list and rejects the strings in a second list. This started Peter Norvig, the well-known computer scientist and director of research at Google, thinking about the problem. Is it possible to write a program that would create a regular expression to solve the xkcd problem? The result is an NP hard problem that needs AI-like techniques to get an approximate answer. To find out more, read the complete description, including Python code, on Peter Norvig's blog. It ends with this challenge: 'I hope you found this interesting, and perhaps you can find ways to improve my algorithm, or more interesting lists to apply it to. I found it was fun to play with, and I hope this page gives you an idea of how to address problems like this.'"

Why Do Projects Continue To Support Old Python Releases? 432

On Planet Python, Gregory Szorc asks why many projects continue to support Python releases prior to 2.7, when they are all EOLed (2.4 in 2008, 2.5 in 2011, and 2.6 last October), and Python 2.7 provides a clear upgrade path to Python 3. Quoting: "I think maintainers of Python projects should seriously consider dropping support for Python 2.6 and below. Are there really that many people on systems that don't have Python 2.7 easily available? Why are we Python developers inflicting so much pain on ourselves to support antiquated Python releases? As a data point, I successfully transitioned Firefox's build system from requiring Python 2.5+ to 2.7.3+ and it was relatively pain free." Shortly after posting, other developers responded with their reasons for using older Python releases. First, Rob Galanakis of CCP (EVE Online) explains the difficulties involved in upgrading a mature commercial project embedding Python. Nathan Froyd adds "I think this list of reasons to upgrade misses the larger point in providing software for other people: You do not get to tell your users what to do. ... Maybe those users don’t have sufficient control over their working environments to install a new version of Python. ... Maybe those users rely on certain APIs only available in older versions of Python and don’t wish to take an indeterminate amount of time to rewrite (retest, recertify, etc. etc.) their software. ... Maybe those users are just rationally lazy and don’t want to deal with downloading, configuring, and installing a new version of Python, plus dealing with inevitable fallout, when the old version has worked Just Fine for everything else."
