Debian GNU/Linux 10 “Buster” Operating System Officially Released, Download Now

Sunday 7th of July 2019 01:17:00 AM
The Debian Project has officially announce today the release and general availability of the Debian GNU/Linux 10 "Buster" operating system series as the new stable version of Debian.

More than two years in development, Debian Buster or Debian 10 has now been declared stable, available for download for all supported architectures, and ready for deployment in production environments. It's a major release that brings numerous updated components and lots of new features and improvements.

"After 25 months of development the Debian project is proud to present its new stable version 10 (code name buster), which will be supported for the next 5 years thanks to the combined work of the Debian Security team and of the Debian Long Term Support team," reads the release announcement.

Learn object-oriented programming with Python

Sunday 7th of July 2019 01:14:23 AM
In my previous article, I explained how to make Python modular by using functions, creating modules, or both. Functions are invaluable to avoid repeating code you intend to use several times, and modules ensure that you can use your code across different projects.

Debian 10 (“Buster”) has been released

Sunday 7th of July 2019 01:06:18 AM
Debian version 10, code named "Buster", has been released. It has lots of new features, including: "In this release, GNOME defaults to using the Wayland display server instead of Xorg. Wayland has a simpler and more modern design, which has advantages for security. However, the Xorg display server is still installed by default and the default display manager allows users to choose Xorg as the display server for their next session. Thanks to the Reproducible Builds project, over 91% of the source packages included in Debian 10 will build bit-for-bit identical binary packages. This is an important verification feature which protects users against malicious attempts to tamper with compilers and build networks. Future Debian releases will include tools and metadata so that end-users can validate the provenance of packages within the archive. For those in security-sensitive environments AppArmor, a mandatory access control framework for restricting programs' capabilities, is installed and enabled by default. Furthermore, all methods provided by APT (except cdrom, gpgv, and rsh) can optionally make use of seccomp-BPF sandboxing. The https method for APT is included in the apt package and does not need to be installed separately." More information can be found in the release notes.

Hands on with Windows 1.11, the Stranger Things tie-in you didn’t know you needed (minor spoilers)

Saturday 6th of July 2019 08:07:39 PM
This week Microsoft has been teasing users across the web with a series of Windows 1.0 announcements. That operating system originally came out in 1985, and the latest season of Netflix’s Stranger Things is set in the same year, so there was never any doubt that the teasers and the show were linked in some way. But how? On Friday Microsoft revealed we’d know the answer on Monday, but we now know exactly what’s coming -- Windows 1.11. Yes, it’s Windows 1.0, but turned up to Eleven -- of course it is. Eagle-eyed Windows 10 users have spotted a new… [Continue Reading]

This Week In Techdirt History: June 30th – July 6th

Saturday 6th of July 2019 07:00:00 PM

Five Years Ago

This week in 2014, it was slightly refreshing to see the new NSA boss refrain from Keith Alexander's sky-is-falling hyperbole when talking about the fallout of the Snowden revelations. We continued to learn more about already-published documents — such as the fact that the FBI and CIA were joining the NSA in the use of "backdoor searches" — as well as getting new revelations, such as details on how the FISA Court (which incidentally also this week issued a memorandum letting bulk metadata collection continue, had given the NSA incredibly broad powers to spy on almost any country. The EFF was launching a new lawsuit against the agency too, this time over its procedures for dealing with zero-day vulnerabilities, and over in the other major arena of federal government secrecy, a court ordered the DOJ to release the other secret drone strike memo it had referenced in documents the previous week.

Meanwhile, in the wake of Aereo's shutdown, the CEO of CBS was twisting reality to call the ruling "pro-consumer", and we noted how the uncertainty it created may have killed the all-important Cablevision ruling about remote DVRs, but it was impossible to be sure.

Ten Years Ago

Speaking of the Cablevision ruling, it was this week in 2009 that the Supreme Court refused to hear the case and left the appeals court ruling in place. We were just beginning to get our heads around the scope of automated copyright settlement letter shakedowns, as well as the ridiculous copyright situation faced by academics who want to share their work. Microsoft, Yahoo and Real were all sued for making a misstep in the music copyright maze, the RIAA scored an easy and expected legal win against Usenet.com while Jammie Thomas officially appealed the constitutionality of the award in her case, and L'Oreal was continuing its crusade to hold eBay responsible for its users' actions. This was also the week that a district court infamously blocked publication of an unofficial sequel to Catcher In The Rye, reminding us that copyright is one area where the government doesn't blink about banning books.

Fifteen Years Ago

Even all the way back in 2004, it was barely news to discover that lots of big companies routinely share customer data without permission or even disclosure. It was perhaps even less surprising to learn that people were opposed to the RIAA suing downloaders, or that CAN SPAM was still a failure at stopping spam (especially with 20% of Americans admitting they'd bought stuff from spam). Also not especially surprising was the latest failure of broadband-over-power-lines or, sadly, the Senate passing yet another slavishly pro-Hollywood bill easily via voice vote. But, though still not exactly "surprising", it was encouraging and inspiring to see the EFF kick into high-gear with its bad-patent-busting efforts that continue to this day.

Cold case files: fossilized skull shows evidence of 33,000-year-old murder

Saturday 6th of July 2019 06:00:18 PM

Some 33,000 years ago, a man was violently clubbed to death by a left-handed attacker wielding a club or similar object. That's the conclusion of an international team of scientists, who published the results of their forensic analysis in a recent paper in PLOS ONE.

The so-called Cioclovina calvaria is a fossilized skull around 33,000 years old, discovered in a cave in South Transylvania in 1941 during a mining operation. That makes it one of the earliest fossilized human remains yet known, so naturally it's been studied extensively by scientists interested in learning more about the Upper Paleolithic period, which started around 40,000 to 45,000 years, and marks the major dispersal of modern humans in Europe.

"The Cioclovina individual is particularly important, as it is one of the earliest and relatively complete skulls of modern Europeans from the Upper Paleolithic period," co-author Katerina Harvati of Eberhard Karls University of Tubingen in Germany told Live Science. "Human remains from this period are very rare and often very fragmentary."

How the Internet kept my favorite musician alive, 20 years later

I'm a firm believer in the power of a live performance. A television broadcast or DVD doesn't capture the same thing as a theatrical production or a concert. You gotta be there.

But what about when you can't? What recourse is there when you're in love with an artist or performer who you can't physically interact with for any number of reasons?

I've thought about this for decades from a few perspectives: as a former full-time music critic; as a frequent chronicler of how information is presented and exchanged online; and perhaps most of all, as a music fan who had one freaking band slip through his hands.

The OpenStack Train keeps chugging on

SUSE, formerly a Platinum member of the OpenStack Foundation, may have left the open-source, Infrastructure-as-a-Service (IaaS) OpenStack cloud, but the project is going to move forward with the forthcoming 20th release of OpenStack: Train. That's because while SUSE may no longer find OpenStack profitable, others are finding it works well for them and for their customers. "OpenStack is the market's leading choice of open-source infrastructure for containers, VMs and bare metal in private cloud," said Mark Collier, COO of the OpenStack Foundation in a statement.
