New submitter omar.sahal writes "Bret Victor demoed the idea of instant feedback on your code. ... Allowing the programmer to instantly see what his program is doing. Chris Granger has turned this novel idea into Light Table — a new IDE designed to make use of Victor's insights." The screenshots make this look like it could be genuinely useful — like a much fancier and more functional combination of features from SLIME and Speedbar. There's a Google group for those wanting to track development. There's no code yet, but source is promised: "I can guarantee you that Light Table will be built on top of the technologies that are freely available to us today. As such, I believe it only fair that the core of Light Table be open sourced once it is launched, while some of the plugins may remained closed source."

An anonymous reader writes "The University of Pittsburgh has been plagued with 78 bomb threats (and counting) since February 14. It started low-tech, with handwritten notes, but has progressed to anonymous emails. Nearly every campus building has been a target. The program suspected is anonymous mailer Mixmaster. The university has been evacuating each building when threats come in (day or night), and police departments from around Allegheny County have offered assistance with clearing each building floor by floor with bomb sniffing dogs. There is a popular tracking blog set up by a student as well as a growing Reddit community. Is there any foreseeable defense (forensic or socially engineered) to a situation like this?"

The Bad Astronomer writes "Astronomers have used two big telescopes to create an infrared survey of the Milky Way that is the largest of its kind: the resulting image has an incredible 150,000 megapixels containing over a billion stars. Something that large is difficult to use, so they also made a pan-and-zoom version online which should keep you occupied for quite some time. These data will be used to better understand star formation in our Milky Way, and how far more distant galaxies and quasars behave." The interactive image is powered by IIPImage which happens to be Free Software and is cool in its own right (right click the image to get help — it has a full set of keybindings for navigation).

You may have noticed that we've posted quite a few original videos on Slashdot in the past few months. Rather than being the work of a few rogue editors with newly-acquired Christmas cameras, this was part of the groundwork for a new site we're launching today. SlashdotTV, found at http://tv.slashdot.org, will let you easily find and watch all of our videos in one convenient location. In addition to Slashdot content, you also can watch videos from our sister sites, SourceForge and ThinkGeek. The site is brand new, and we're interested in hearing your feedback -- what you think about it, and what kind of videos you'd like to see. Currently, you can embed our videos on your own site or show them to your friends with our share feature. Commenting is coming soon. Check back often for new videos, and keep watching!

You've probably noticed that Slashdot's been running some video lately. There are a lot of interesting people and projects in the world we'd like to present in video form, but some of them are too far away for the corporate overlords to sponsor travel to shoot footage in person. (Another reason my dream of parachuting to McMurdo Station will probably never manifest.) We've been playing around with several things on both the software and hardware side, but in truth, all of them have some flaws — whether it's flaky sound (my experience with the otherwise pleasing RecordMyDesktop on Linux), sometimes garbled picture (Skype, even on seemingly fast network connections), or video quality in general. (Google Hangouts hasn't looked as good as Skype, for instance. And of the webcams built into any of the laptops we've tried, only Apple's were much worth looking at. Logitech's HD webcams seem to be a decent bargain for their quality.) We've got a motley bunch of Linux, OS X, and Windows systems, and can only control what's on our side of the connection: interviewees may have anything from a low-end laptop with a built-in webcam to elaborate conferencing tools — which means the more universal the tools, the better. (There may not be any free, open source, high-quality, cross-platform video conferencing tools with built-in capture and a great UI, but the closer we can get, the better.) With all that in mind, what tools and workflow would you suggest for capturing internet conversations (with video and sound), and why? Approaches that minimize annoyance to the person on the other end of the connection (like the annoyance of signing up for an obscure conferencing system) are especially valuable. We'd like to hear both sides, so please chime in if you've had especially good or bad experiences with capturing remote video like this.

Thinkcloud writes "The Document Foundation has released LibreOffice 3.5.1. Some of the core fixes include: don't crash for empty input data in charts, UI fix on PDF export dialog, don't copy page styles into temporary clipboard doc, and use the correct db range for the copy. 'Another milestone for the LibreOffice project was hit this past month as well. "The number of TDF hackers has overtaken the threshold of 400 code developers, with a large majority of independent volunteers and several companies paying full time hackers." Although some are paid developers, no company employs more than 7% of developers, keeping the project independent and self-governing.'"

An anonymous reader tipped us to an interview with Phillip Lee, author of Brewtarget, one of the best pieces of Free brewing software available (it's even in Debian). The interview discusses some of the technical decisions made (why Qt and Cmake?), and mentions a bit of the plans for future development: "The way the database was designed previously really hadn't been changed since the my first code in 2008, and we were running into a brick wall with some of the features we wanted. After we move to SQLite, there will be quite a lot of new features like being able to search through the ingredients in the database and stuff like that. I also plan to add some water chemistry tools for people that like to alter the ions and salts to fit a particular profile." (The last bit about water salt modifications comes as a relief to at least this brewer.)

vinn writes "Wine 1.4 was released today and includes support for a wide range of applications, including Office 2010. There are some major architectural changes, including a built-in DIB engine for better graphics display and a new audio stack designed around the newer Vista / Win 7 system and integrated into the native audio system. Almost every other subsystem received substantial updates, including Direct3D, the Gecko-based web browsing components, and better internationalization. The release notes contain more detail and you can download the source code now, or wait for packages to appear soon."

PatPending writes with this excerpt from TorrentFreak: "The RetroShare network allows people to create a private and encrypted file-sharing network. Users add friends by exchanging PGP certificates with people they trust. All the communication is encrypted using OpenSSL and files that are downloaded from strangers always go through a trusted friend. In other words, it's a true Darknet and virtually impossible to monitor by outsiders. RetroShare founder DrBob told us that while the software has been around since 2006, all of a sudden there's been a surge in downloads. 'The interest in RetroShare has massively shot up over the last two months,' he said."

wiredmikey writes "The popular free security tool HijackThis has been open sourced by its owner, Trend Micro. The tool scans systems to find settings that may have been modified by spyware, malware or other programs that have wiggled their way onto a system and caused problems. Downloaded over 10 million times, HijackThis generates reports to help users analyze and fix an infected or problem computer. But the tool is not designed for novices – and doesn't actually determine what's good or bad. That's up to you, but it is a good way to keep an eye on things and possibly locate anomalies that may have been missed by other security products. Trend Micro warns that if you don't know what you're doing, it's probably not a good idea to make any changes to your computer settings and system files. Trend Micro acquired the tool from creator Merijn Bellekom in 2007, and has offered it for free ever since, but now is making the code available to the public. The code, originally written in Visual Basic, is now officially available at Sourceforge here."

An anonymous reader wrote in with news of the latest release of ReactOS, a project to create a complete reimplementation of Windows. The highlights of this release are the integration of a new network stack based upon lwIP, the ability to build using Microsoft's C compiler, and Wifi support. There are a few options for trying it out (emulator image and a livecd amongst others) and source code over at Sourceforge.

First time accepted submitter tonique writes "Perl Data Language (PDL) 2.4.10 has been released. Highlights of the new release are automatic multi-thread support, support for data structures larger than 2 GB and POSIX threads support. Also available is the first draft of the new PDL book. PDL is especially suitable for scientists. For those not in the know, 'PDL gives standard Perl the ability to compactly store and speedily manipulate the large N-dimensional data arrays which are the bread and butter of scientific computing.' Commercial languages used for the same purpose include MATLAB and IDL."

wiredmikey writes "As Anonymous initiated what it said will be the 'largest attack ever on government and music industry sites' in response to actions taken by the Justice Department against operators of file sharing site Megaupload.com, downloads of a popular DoS attack tool have spiked. While the Denial of Service tool known as the 'Low Orbit Ion Cannon' (LOIC) was developed by the 'good guys' to stress test websites, it has been a favorite tool of Anonymous to take its targets offline via denial of service attacks. Interactions seen on Twitter and IRC, made it clear that the action against MegaUpload has sparked many more individuals to get involved in the online protests and download the LOIC to take part in the attacks and has resulted in a massive spike in downloads according Slashdot sister site Sourceforge."

mikejuk writes with an excerpt from an article at i-programmer about a neat graphics demo written in Dart: "One of the difficulties in getting a new computer language accepted by a wider audience is that there is doubt that it is real. Is it a toy language that just proves a concept or can it do real work? In the case of Dart, which is Google's replacement for JavaScript, the development is speeding ahead at a rate that is impressive but worrying. To prove that Dart is already a language that can be used, we now have a port of the well known 2D physics engine Box2D, the one Angry Birds uses, to Dart." Box2D has previously been ported to Javascript. Source is available at Google Code (under the Apache license). Note that you'll need Chromium to run the demos.

An anonymous reader writes "ScientiaMobile, the company formed behind the open source library WURFL, an API used to do mobile device detection for web applications, has issued a DMCA takedown notice against the OpenDDR project on Github. ScientiaMobile claims that OpenDDR is 'ripping them off' by forking their database, which used to be licensed under a liberal license. Newer versions of the device database are licensed under restrictive licenses which do not allow any modification or redistribution."

Kevin Fishburne writes "After years of work, creator Benoît Minisini and friends are just in time for New Year's celebrations with the first stable release of GAMBAS 3. Per their web site, 'Gambas is a free development environment based on a Basic interpreter with object extensions, a bit like Visual Basic (but it is NOT a clone !).' GAMBAS is component-based, so check out the list for an idea of what you can do with it."

First time accepted submitter PraxisGuitars writes "I am working on developing an open source electric guitar. I wish to make the basic structural system completely open and free, with a standardized interface allowing different body shapes and modules to be bolted on. I am having trouble figuring out the best way to release the files. There seem to be at least half a dozen open source licenses out there; The Thingiverse has some precedent for open source 3d data, but version control seems like it might be difficult. I have looked into sourceforge and github, but don't know enough to know if that would be the best choice. Are there other precedents out there? Is there a better way?"

Bill Currie writes "After many years, QuakeForge 0.6.0 has finally been released, just in time for the 12th anniversary of the release of the Quake source code. Happy birthday, GPL Quake. Merry Christmas, Quake fans." The release page shows a few 0.5.99 beta releases made starting earlier this month, the first since 2004. Sometime in that void of time development moved to git, and there has quite a bit of work going on in the main tree.
