Linux 4.20 Released in Time for Christmas (betanews.com) 47

Linus Torvalds has announced the general availability of v4.20 of the Linux kernel. In a post to the Linux Kernel Mailing List, Torvalds said that there was no point in delaying the release of the latest stable version of the kernel just because so many people are taking a break for the holiday season. From a report: He says that while there are no known issues with the release, the shortlog is a little longer than he would have liked. However "nothing screams 'oh, that's scary'", he insists. The most notable features and changes in the new version includes: New hardware support! New hardware support includes bringing up the graphics for AMD Picasso and Raven 2 APUs, continued work on bringing up Vega 20, Intel has continued putting together its Icelake Gen 11 graphics support, there is support for the Hygon Dhyana CPUs out of China based upon AMD Zen, C-SKY 32-bit CPU support, Qualcomm Snapdragon 835 SoC enablement, Intel 2.5G Ethernet controller support for "Foxville", Creative Sound Blaster ZxR and AE-5 sound card support, and a lot of smaller additions.

Besides new hardware support when it comes to graphics processors, in the DRM driver space there is also VCN JPEG acceleration for Raven Ridge, GPUVM performance work resulting in some nice Vulkan gaming boosts, Intel DRM now has full PPGTT support for Haswell/IvyBridge/ValleyView, and HDMI 2.0 support for the NVIDIA/Nouveau driver. On the CPU front there are some early signs of AMD Zen 2 bring-up, nested virtualization now enabled by default for AMD/Intel CPUs, faster context switching for IBM POWER9, and various x86_64 optimizations. Fortunately the STIBP work for cross-hyperthread Spectre V2 mitigation was smoothed out over the release candidates that the performance there is all good now.

Btrfs performance improvements, new F2FS features, faster FUSE performance, and MDRAID improvements for RAID10 round out the file-system/storage work. One of the technical highlights of Linux 4.20 that will be built up moving forward is the PCIe peer-to-peer memory support for device-to-device memory copies over PCIe for use-cases like data going directly from NICs to SSD storage or between multiple GPUs.

Never understood who thought this was a good idea.

People under severe memory constraints who need to use pointers that take up only half the space? People under severe performance constraints who can't spare the cycles to copy 64-bit pointers or do 64-bit lookups?

Why are said people using a 64-bit CPU in the first place, then? Let them use a 32-bit ARM CPU or something, and stop gimping the x86_64 architecture.

Autocompletion I can do without (or with, it doesn't really matter to me). But I must have syntax colouring; it makes it so much easier to scan code looking for a certain pattern, that it's now painful if I look at code without it.

I actually have a specific interest in this topic, since I'm an instructor in Computer Science, and we are currently comtemplating just such a move. Similar to you, I'm always amazed at the number of students that are completely lost without the IDE. They want to load up this huge, multi-gigabyte monstrosity of a program (Eclipse, etc) to write a 50 line Java program. Just boggles the mind.

WhatsApp Co-Founder Tells Everyone To Delete Facebook, Further Fueling the #DeleteFacebook Movement (theverge.com) 307

"In 2014, Facebook bought WhatsApp for $16 billion, making its co-founders -- Jan Koum and Brian Acton -- very wealthy men," reports The Verge. "Koum continues to lead the company, but Acton quit earlier this year to start his own foundation." Today, Acton told his followers on Twitter to delete Facebook. From the report: "It is time," Acton wrote, adding the hashtag #deletefacebook. Acton, who is worth $6.5 billion, did not immediately respond to a request for comment. Nor did Facebook and WhatsApp. It was unclear whether Acton's feelings about Facebook extend to his own app. But last month, Acton invested $50 million into Signal, an independent alternative to WhatsApp. The tweet came after a bruising five-day period for Facebook that has seen regulators swarm and its stock price plunge following concerns over data privacy in the wake of revelations about Cambridge Analytica's misuse of user data. Acton isn't the only one taking to Twitter to announce their breakup with Facebook. The #DeleteFacebook movement is gaining steam following the New York Times' report about how the data of 50 million users had been unknowingly leaked and purchased to aid President Trump's successful 2016 bid for the presidency. For many users, the news "highlighted the danger of Facebook housing the personal information of billions of users," reports SFGate. "And even before the Cambridge Analytica news, Facebook has been grappling with its waning popularity in the U.S. The company lost 1 million domestic users last quarter -- its first quarterly drop in daily users."

No, they didn't make it up. Just because you don't agree with an opinion, you can't say it is made up. I've also tried compilation in Linux in Windows, and it is much slower. I've determined it's at least related to the abysmal disk I/O speed in Windows compared to Linux. But it _is_ a real problem, and isn't just 'made up'.

Comment Re:All french everywhere (Score -1) 344

Except in the case of Quebec and Canada, French is mandated in all English-primary provinces, but English doesn't enjoy the same privilege in Quebec. So Quebec'ers, special snowflakes that they are, require French in schools, signage, etc everywhere in the country, even in the smallest town/village that has probably never (and probably *will never*) see a French person. Meanwhile, if you try to even speak English in Quebec, they will ignore you. And if you suggest that all signage also include English (as they require for their language in the rest of the ENTIRE country), it amounts to sacrilege.

Personally, I don't think even the French themselves (ie, people actually from France) are as conceited and stuck-up and the French in Quebec.

Comment Re:"Why Intel gave it the mind-numbingly boring na (Score 2) 141

The "point" is that Intel, Microsoft, and many large 'technical' corporations are apparently more concerned with marketing than technical prowess. Consider that Intel spends more on marketing each year than AMDs entire R&D budget.

Maybe if they spent half the time, energy and money on technical stuff as they do on slimy marketing, this issue wouldn't have happened in the first place.
