The GNU C Library version 2.24 is now available

Friday 5th of August 2016 12:04:31 AM
The 2.24 version of the GNU C Library (glibc) has been released. It comes with lots of bug fixes, including five for security vulnerabilities (four stack overflows and a memory leak). Some deprecated features have been removed, as well as deprecating the readdir_r() and readdir64_r() functions in favor of readdir() and readdir64(). There are also additions to the math library (nextup*() and nextdown*()) to return the next representable value toward either positive or negative infinity.

Breaking through censorship barriers, even when Tor is blocked (Tor Blog)

Thursday 4th of August 2016 11:53:10 PM
The Tor Blog looks at using Pluggable Transports to avoid country-level Tor blocking. There are some new easy-to-follow graphical directions for using the transports. "Many repressive governments and authorities benefit from blocking their users from having free and open access to the internet. They can simply get the list of Tor relays and block them. This bars millions of people from access to free information, often including those who need it most. We at Tor care about freedom of access to information and strongly oppose censorship. This is why we've developed methods to connect to the network and bypass censorship. These methods are called Pluggable Transports (PTs). Pluggable Transports are a type of bridge to the Tor network. They take advantage of various transports and make encrypted traffic to Tor look like not-interesting or garbage traffic. Unlike normal relays, bridge information is kept secret and distributed between users via BridgeDB."

Some news from LWN

Wednesday 3rd of August 2016 09:26:54 PM
It has been some time since our last update on the state of LWN itself. That's somewhat by design, as we'd rather be writing about the community and the code than ourselves. Occasionally, though, we do like to update our readers and subscribers on the state of the operation, especially when there is some news to report, as is the case now.

[$] Statistics from the 4.7 development cycle

Tuesday 2nd of August 2016 08:10:59 PM
The 4.7 kernel was released on July 24, so longtime readers might be wondering where the usual development statistics are. We're running a little late this time around, but for good reason — Greg Kroah-Hartman obtained information from a large number of developers on who they work for, and we're now able to use that information to produce better numbers. Of course, the overall story hasn't changed a whole lot — kernel development is relatively boring and predictable these days — but each cycle still has a few noteworthy points.

    The popular, open-source, and cross-platform MPV video player software received a new update, version 0.20.0, which comes only two weeks after the previous 0.19.0 maintenance release. MPV 0.20.0 is not a major update, and, according to the release notes, it only implements a couple of new options and commands, such as "--video-unscaled=downscale-big" for changing the aspect ratio. Additionally, the MPlayer-based video playback application also gets the "--image-display-duration" option for controlling the duration of image display, and a new "dcomposition" flag for controlling DirectComposition.

  • Report: If DOD Doesn't Embrace Open Source, It'll 'Be Left Behind'
    Unless the Defense Department and its military components levy increased importance on software development, they risk losing military technical superiority, according to a new report from the Center for a New American Security. In the report, the Washington, D.C.-based bipartisan think tank argues the Pentagon, which for years has relied heavily on proprietary software systems, “must actively embrace open source software” and buck the status quo. Currently, DOD uses open source software “infrequently and on an ad hoc basis,” unlike tech companies like Google, Amazon and Facebook that wouldn’t exist without open source software.
  • The Honey Trap of Copy/Pasting Open Source Code
    I couldn’t agree more with Bill Sourour’s article ‘Copy.Paste.Code?’ which says that copying and pasting code snippets from sources like Google and StackOverflow is fine as long as you understand how they work. However, the same logic can’t be applied to open source code. When I started open source coding at the tender age of fourteen, I was none the wiser to the pitfalls of copy/pasting open source code. I took it for granted that if a particular snippet performed my desired function, I could just insert it into my code, revelling in the fact that I'd just gotten one step closer to getting my software up and running. Yet, since then, through much trial and error, I’ve learned a thing or two about how to use open source code effectively.
  • Affordable, Open Source, 3D Printable CNC Machine is Now on Kickstarter
    The appeals of Kickstarter campaigns are many. There are the rewards for backers, frequently taking the form of either deep discounts on the final product or unusual items that can’t be found anywhere else. Pledging to support any crowdfunding campaign is a gamble, but it’s an exciting gamble; just browsing Kickstarter is pretty exciting, in fact, especially in the technological categories. Inventive individuals and startups offer new twists on machines like 3D printers and CNC machines – often for much less cost than others on the market.
  • Open Standards and Open Source
    Much has changed in the telecommunications industry in the years since Standards Development Organization (SDOs) such as 3GPP, ITU and OMA were formed. In the early days of telecom and the Internet, as fundamental technology was being invented, it was imperative for the growth of the new markets that standards were established prior to large-scale deployment of technology and related services. The process for development of these standards followed a traditional "waterfall" approach, which helped to harmonize (sometimes competing) pre-standard technical solutions to market needs.

  • The Voicemail Scammers Never Got Past Our OpenBSD Greylisting
    We usually don't see much of the scammy spam and malware. But that one time we went looking for them, we found a campaign where our OpenBSD greylisting setup was 100% effective in stopping the miscreants' messages. During August 23rd to August 24th 2016, a spam campaign was executed with what appears to have been a ransomware payload. I had not noticed anything particularly unusual about the and friends setup that morning, but then Xavier Mertens' post at Voice Message Notifications Deliver Ransomware caught my attention in the tweetstream, and I decided to have a look.
