Ah, The Memories...
by Lawrence D'Oliveiro 09 Jul '15

09 Jul '15

In the wake of the latest round of Microsoft’s layoffs, it seems apropos to remember the time they held a mock funeral for their competition at the time of the Windows Phone 7 launch: <http://appleinsider.com/articles/10/09/10/microsoft_employees_hold_funeral_…>. “Research firm Gartner predicted ... Nokia Symbian and Google Android [would be] first and second with 30.2 percent and 29.6 percent [market share] respectively [in 2014].” Did anybody notice any Symbian phones still on sale? Android had more like 80%...

Debian To Switch From Libav Back To ffmpeg
by Lawrence D'Oliveiro 09 Jul '15

09 Jul '15

I’ve been using FFmpeg for years. I always built it from source, because I was aware that prebuilt distro packages were 1) well behind the latest development tree, and 2) likely to leave out features because of patent issues. So I hardly noticed the whole Libav fork issue <https://lwn.net/Articles/433347/>. I was dimly aware that my Debian system had these “libav” packages on it, that looked and behaved just like FFmpeg in everything but name. But I hardly ever used them—not directly. Then, last year, I found out a bit more about what really happened <https://lwn.net/Articles/607591/>, and why Debian went with the fork. Can you say “conflict of interest”? (Well, that’s how it looks like to me.) So now, Debian has officially decided to return to the original FFmpeg project <http://lwn.net/Articles/650495/>.

Amazon's New SSL/TLS Implementation In 6,000 Lines of Code
by Peter Reutemann 01 Jul '15

01 Jul '15

'Amazon has announced a new library called "s2n," an open source implementation of SSL/TLS, the cryptographic security protocols behind HTTPS, SSH, SFTP, secure SMTP, and many others. Weighing in at about 6k lines of code, it's just a little more than 1% the size of OpenSSL, which is really good news in terms of security auditing and testing. OpenSSL isn't going away, and Amazon has made clear that they will continue to support it. Notably, s2n does not provide all the additional cryptographic functions that OpenSSL provides in libcrypto, it only provides the SSL/TLS functions. Further more, it implements a relatively small subset of SSL/TLS features compared to OpenSSL.' -- source: http://it.slashdot.org/story/15/07/01/0214248 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 858-5174 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

GMT Versus UTC
by Lawrence D'Oliveiro 01 Jul '15

01 Jul '15

It still seems to be common among groups outside the computing and scientific worlds to talk about “GMT” rather than “UTC”. The trouble with “GMT” is that it doesn’t seem to be clearly defined; it might or might not differ from UTC by up to 0.9 seconds. The (unadjusted) time reference defined by an official collection of atomic clocks worldwide is called “TAI”. This pays no heed to the slowing rotation of the Earth. Astronomers prefer a time reference called “UT1”, which is based on the actual rotation of the Earth (subject to some time-averaging, I think). The definition of “UTC” comes from TAI, adjusted by applying leap seconds. These accumulate as needed so as to keep UTC within 0.9 seconds of UT1, and we are currently up to 36 of them. That is, at 0:00:00 UTC today, TAI was actually 0:00:36. The trouble with GMT is that it is not officially clear whether it is the same as UT1, or the same as UTC. Given that it was originally defined at the Greenwich Observatory, which was (is?) run by astronomers, one would think they would make it the same as UT1. But the practical fact is, our usual everyday timekeeping is based on standard time zones, which are all defined as whole-second (indeed, whole multiples of a half-hour) offsets from UTC.

How Long Can A Filename Be?
by Lawrence D'Oliveiro 01 Jul '15

01 Jul '15

Allowed length of an individual file/directory name: ldo(a)theon:~> getconf NAME_MAX / 255 Allowed length of a full path name: ldo(a)theon:~> getconf PATH_MAX / 4096 The answers can be filesystem-specific; here “/” is an ext3 filesystem. But on my /home, which is ext4, I get the same numbers.

So How Did Your Leap-Second Go?
by Lawrence D'Oliveiro 01 Jul '15

01 Jul '15

At noon today NZ time, an extra second was inserted into UTC, the time kept by the world’s atomic clocks. The time that was one second before midnight UTC (one second before noon NZST) became two seconds before intead: after 23:59:59 UTC came 23:59:60 UTC, before ticking over to 0:00:00 UTC. The previous time this happened, three years ago, several Linux-based systems malfunctioned. No word yet on how this one went... <http://lwn.net/Articles/648313/>

Doing For Video What PulseAudio Did For Audio
by Lawrence D'Oliveiro 01 Jul '15

01 Jul '15

Pinos is a project to allow better handling of video input across multiple applications. Pinos will make it easier to switch cameras in applications and for the same camera source to be used by multiple apps simultaneously, there will be support for multiple types of video inputs, GStreamer integration, and some audio support. Pinos should allow better screencasting within GNOME 3, video support for desktop sandboxes, and many other potential use-cases. In an email, Christian mentioned why it didn't end up being called PulseVideo over name squatting. <http://phoronix.com/scan.php?page=news_item&px=Fedora-Pinos-Announced>
