"Hack" Typeface Is Open Source, Easy On the IDEs 205

Ars Technica writes that "At SourceFoundry.org this week, programmer Chris Simpkins debuted the 2.0 version of Hack, an open-source typeface designed specifically for use in source code." The revamped font is "characterized by a large x-height, wide aperture, and low contrast design in order to be 'highly legible' at common coding text sizes," and the font specimen shows how legible it is right down to downright tiny sizes, though Simpkins says the sweet spot is between 8 and 12 pixels. Hack's roots are in the libre, open source typeface community, and the project expands upon the contributions of the Bitstream Vera & DejaVu projects. ... Simpkins has been working on the project throughout 2015, and he tweeted that this latest version includes "new open type features, changes in weights, significant changes in spacing, Powerline glyphs, and more." The typeface now comes with four font styles: Regular, Bold, Oblique, and Bold Oblique.

AMD's R9 Fury On Open-Source: Prepare for Disappointment, For Now 43

An anonymous reader writes: With Linux 4.3 AMD is adding the initial open-source driver for the R9 Fury graphics cards. Unfortunate for Linux gamers, the R9 Fury isn't yet in good shape on the open-source driver and it's not good with the Catalyst Linux driver either as previously discussed. With the initial code going into Linux 4.3, the $550 R9 Fury runs slower than graphics cards like the lower-cost and older R7 370 and HD 7950 GPUs, since AMD's open-source developers haven't yet found the time to implement power management / re-clocking support. The R9 Fury also only advertises OpenGL 3.0 support while the hardware is GL4.5-capable and the other open-source AMD GCN driver ships OpenGL 4.1. It doesn't look like AMD has any near-term R9 Fury Linux fix for either driver, but at least their older hardware is performing well with the open-source code.

MIAOW Open Source GPU Debuts At Hot Chips 44

alexvoica writes: The first general-purpose graphics processor (GPGPU) now available as open-source RTL was unveiled at the Hot Chips event. Although the GPGPU is in an early and relatively crude stage, it is another piece of an emerging open-source hardware platform, said Karu Sankaralingam, an associate professor of computer science at the University of Wisconsin-Madison. Sankaralingam led the team that designed the Many-core Integrated Accelerator of Wisconsin (MIAOW). A 12-person team developed the MIAOW core in 36 months. Their goal was simply to create a functional GPGPU without setting any specific area, frequency, power or performance goals. The resulting GPGPU uses just 95 instructions and 32 compute units in its current design. It only supports single-precision operations. Students are now adding a graphics pipeline to the design, a job expected to take about six months.

Ten Dropbox Engineers Build BSD-licensed, Lossless 'Pied Piper' Compression Algorithm 172

An anonymous reader writes: In Dropbox's "Hack Week" this year, a team of ten engineers built the fantasy Pied Piper algorithm from HBO's Silicon Valley, achieving 13% lossless compression on Mobile-recorded H.264 videos and 22% on arbitrary JPEG files. Their algorithm can return the compressed files to their bit-exact values. According to FastCompany, "Its ability to compress file sizes could actually have tangible, real-world benefits for Dropbox, whose core business is storing files in the cloud."The code is available on GitHub under a BSD license for people interested in advancing the compression or archiving their movie files.

Ubuntu Is the Dominant Cloud OS 167

An anonymous reader writes: According to a new report by Cloud Market, Ubuntu is more than twice as popular on Amazon EC2 as all other operating systems combined. Given that Amazon Web Services has 57% of the public cloud market, Ubuntu is clearly the most popular OS for cloud systems. This is further bolstered by a recent OpenStack survey, which found that more than half of respondents used Ubuntu for cloud-based production environments. Centos was a distant second at 29%, and RHEL came in third at 11%. "In addition to AWS, Ubuntu has been available on HP Cloud, and Microsoft Azure since 2013. It's also now available on Google Cloud Platform, Fujitsu, and Joyent." The article concludes, "People still see Ubuntu as primarily a desktop operating system. It's not — and hasn't been for some time."

Open Source, Collaborative Rich-Text, Web-Based Editor Almost Available 59

johanneswilm writes: Open source web-based editors such as CKEditor and TinyMCE have been available for more than a decade, and some closed source collaborative editors such as Google Docs have been available since 2007. Creating open source, collaborative, rich-text, web-based editors has proven difficult due to lack of standardization of the lower-level browser features. Now Marijn Haverbeke, the developer behind the popular CodeMirror has started such an editor, called Prosemirror, financed through a crowd-funding campaign. Meanwhile the W3C has installed a task force to rapidly standardize and fix the features needed in browsers to easily create richtext and semantic editors.

UNC Scientists Open Source Their Genomic Research 10

ectoman writes: The human genome specifies more than 500 "kinases," enzymes that spur protein synthesis. Four hundred of them are still mysteries to us, even though knowledge about them could spark serious medical innovations. But scientists at the University of North Carolina, Chapel Hill, have initiated an open source effort to map them all—research they think could pioneer a new generation of drug discovery. As members of the Structural Genomics Consortium, the chemical biologists are spearheading a worldwide community project. "We need a community to build a map of what kinases do in biology," one said. "It has to be a community-generated map to get the richness and detail we need to be able to move some of these kinases into drug facilities. But we're just doing the source code. Until someone puts the source code out there and makes it available to everybody, people won't have anything to modify."

'Gynepunks' DIY Gynecology For Underserved Women 59

New submitter Alien7 sends an article about a group of bio-hackers who are out to bring DIY gynecological medicine to women who don't have easy access to it. Under the name GynePunks, they're assembling an arsenal of open-source tools for DIY diagnosis and first-aid care—centrifuges made from old hard drive motors; microscopes from deconstructed webcams; homemade incubators; and 3D printable speculums. ... So far the work is largely focused on diagnosis, and members of the collective are quick to note that what they’re creating is far from a comprehensive solution. It’s limited by some obvious factors—access to materials, a place to put them together, and the time to do it. But where the infrastructure does exist, and people are motivated to do so, it is very possible to establish some useful alternatives for self-care. As an example, Klau pointed to a pilot vinegar test program that’s lowered cervical cancer deaths by some 31 percent among poor women in Mumbai’s slums.

Meet Linux's Newest File-System: Bcachefs 132

An anonymous reader writes: Bcachefs is a new open-source file-system derived from the bcache Linux kernel block layer cache. Bcachefs was announced by Kent Overstreet, the lead Bcache author. Bcachefs hopes to provide performance like XFS/EXT4 while having features similar to Btrfs and ZFS. The bachefs on-disk format hasn't yet been finalized and the code isn't yet ready for the Linux kernel. That said, initial performance results are okay and "It probably won't eat your data — but no promises." Features so far for Bcachefs are support for multiple devices, built-in caching/tiering, CRC32C checksumming, and Zlib transparent compression. Support for snapshots is to be worked on.

City of Munich Struggling With Basic Linux Functionality 394

jones_supa writes: Just like the city planned a year ago, Munich is still calling for a switch back to Windows from LiMux, their Ubuntu derivative. The councilors from Munich's conservative CSU party have called the operating system installed on their laptops "cumbersome to use" and "of very limited use." The letter from the two senior members of the city's IT committee (PDF in German) asks the mayor to consider removing the Linux-based OS and to install Windows and Office. "There are no programs for text editing, Skype, Office etc. installed and that prevents normal use," the letter argues. Another complaint from councilors is that "the lack of user permissions makes them of limited use." These kind of arguments raise eyebrows, as all that functionality is certainly found on Linux.

Linus Torvalds Isn't Looking 10 Years Ahead For Linux and That's OK 108

darthcamaro writes: At the Linuxcon conference in Seattle today, Linus Torvalds responded to questions about Linux security and about the next 10 years of Linux. For security, Torvalds isn't too worried as he sees it just being about dealing with bugs. When it comes to having a roadmap he's not worried either as he just leaves that to others. "I'm a very plodding, pedestrian person and look only about six months ahead," Torvalds said. "I look at the current release and the next one, as I don't think planning 10 years ahead is sane."

Interviews: Ask Dr. Tarek Loubani About Creating Ultra-Low Cost Medical Devices 54

Tarek Loubani is an emergency medicine physician who works as a consultant doctor in the emergency departments in London, Canada and Shifa Hospital in Gaza. He is also an assistant professor at the Department of Medicine at the University of Western Ontario. Tarek has been working in Gaza for the past 5 years, where he made news recently by creating a 3D-printable, 30-cent stethoscope that is better than the world's best $200 equivalent. The need to develop free and open medical devices due to the lack of medical supplies resulting from the blockade, inspired Loubani who hopes the stethoscope is just the beginning of replacing expensive proprietary medical tools. Tarek has agreed to answer any questions you might have. As usual, ask as many as you'd like, but please, one question per post.

Debian Founder: How I Came To Find Linux 136

An anonymous reader writes: Ian Murdock has pretty solid open source cred: in 1993 he founded Debian, he was the CTO of Progeny and the Linux Foundation, and he helped pave the way for OpenSolaris. He has published a post about how he initially joined the Linux ecosystem. Quoting: "[In 1992], I spent most evenings in the basement of the MATH building basking in the green phosphorescent glow of the Z-29 terminals, exploring every nook and cranny of the UNIX system upstairs. ... I was also accessing UNIX from home via my Intel 80286-based PC and a 2400-baud modem, which saved me the trek across campus to the computer lab on particularly cold days. Being able to get to the Sequent from home was great, but I wanted to replicate the experience of the ENAD building's X terminals, so one day, in January 1993, I set out to find an X server that would run on my PC. As I searched for such a thing on Usenet, I stumbled across something called 'Linux.'" How did you come to find Linux?
