SFC's Kuhn in firing line as Linus Torvalds takes aim

LXer - Sat, 2016-08-27 23:01
A few days after he mused that there had been no reason for him to blow his stack recently, Linux creator Linus Torvalds has directed a blast at the Software Freedom Conservancy and its distinguished technologist Bradley Kuhn over the question of enforcing compliance of the GNU General Public Licence.

Noob Gushing Over How Good Linux Is

Reddit - Sat, 2016-08-27 23:00

So just yesterday I installed Linux Mint, after hearing all over the place that Linux is great compared to Windows. And today, I go and play Garry's Mod, and the difference is so noticeable! The game actually loads at a decent rate, unlike Windows. On my Windows 10 partition, I'm sitting there for an hour on average every time I want to do something. The only problem yet I've had is that one of my networks can't connect to it, but luckily I have another one I can use. You guys out there spreading the word about Linux, good for you! You guys really tell the truth when you say how good it is!

Help installing Linux on an old Intel Atom embedded motherboard?

Reddit - Sat, 2016-08-27 22:49

I happened upon some old hardware that I'd like to repurpose. It's a http://b2b.gigabyte.com/products/product-page.aspx?pid=4677#ov

Mini-ITX form factor Intel® Atom™ D2550 1.86GHz processor 2 x SO-DIMM, up to 4GB 1066MHz 2 x GbE LAN ports (Realtek® RTL8111E) 2 x COM ports (2 x internal) 2 x SATA II 3Gb/s ports

It's a slick, silent little box, so I think it'd make a great little server or set top box. I tried booting to a few live distros from USB and I just get stuck at a blinking cursor or a kernel panic.

This thing was actually a commercial appliance that I know was already running a custom linux distro (maybe gentoo based?).

Any advice? Thanks!

Linux installed on USB getting killed on iowait - sometimes.

Reddit - Sat, 2016-08-27 22:26

Hi Guys,

I installed linux on a 16GB USB disk and mounted my ZFS volume from there. It works wonderfully as a NAS. However, i installed PLEX and a couple of other things that are useful to me.

Every now and then some process will pretty much kill the system on IO to the USB.

How can I find out which process that is, and what files it's reading? Fixing it would be easy if I knew what was going on, but it's tough to figure out who's doing it.

lsof shows a lot of open files, but that doesn't mean IO is active.

iotop doesn't allow me to filter per disk, so i can't figure it out because iO to the ZFS volume is obviously OK.

Thanks!

Stuck trying to set up encrypted boot, Xen, and Display Link

Reddit - Sat, 2016-08-27 22:17

Sorry in advance if this is long or the wrong place for this.

I've got a new laptop (Dell XPS 13 Dev Edition) that I'm trying to get set up with full disk encryption, encrypted boot with the /boot and grub on an external flash drive, Xen hypervisor, and Displaylink for an external USB monitor.

With Arch, I was able to get the encryption and external flash set up how I wanted, working flawlessly, but the AUR packages for both Xen and Displaylink are flagged out of date and I wasn't able to make either of them work after a couple hours of troubleshooting (see my post here). I think I could probably get Displaylink to work with a bit more time, but given the Xen issues, I decided to try again with Ubuntu 16.04 LTS. I know that Xen works there (I have an Ubuntu server running Xen right now) and I'm fairly certain Displaylink shouldn't be too much of a problem.

The problem with Ubuntu is that I can't get the encrypted boot setup to work. The biggest problem being that I can't figure out how to add my LUKS keyfile into the initramfs like I was able to on Arch (see my post here) so that it can automatically decrypt the internal SSD on boot (again, like I was able to do on Arch).

I'm fine running either Arch or Ubuntu LTS as the base system, as most everything else will be set up in Xen VMs, though I'd prefer Arch. The problem is that I'm stuck from two different angle on two different distros and I'm not sure which problem is going to be more easily surmountable.

I'm also open to alternate suggestions for different distros and I can go into detail on exactly what steps I've taken so far if anyone is interested.

TL;DR: Stuck trying to get both Xen and encrypted boot working in either Arch or Ubuntu LTS. Suggestions?

Linux Development and LinuxCon

  • Linus Torvalds says GPL was defining factor in Linux's success

    Linus Torvalds and Dirk Hohndel, vice president and chief of open source at VMware, discussed the role that GNU GPL played in the success of Linux during a keynote conversation this week at LinuxCon NA in Toronto.

    Hohndel, who has been involved with the kernel for a very long time, said that during the past 25 years there have been many challenges, and one of the biggest challenges was the possibility of fragmentation. "How do we keep one single kernel?" he asked.

    "I used to be worried about fragmentation, and I used to think that it was inevitable at some point," said Torvalds. “Everyone was looking at the history of Linux and comparing it with UNIX. People would say that it’s going to fail because it's going to fragment. That's what happened before, so why even bother?"

    What made the difference was the license. "FSF [Free Software Foundation] and I don't have a loving relationship, but I love GPL v2," said Torvalds. "I really think the license has been one of the defining factors in the success of Linux because it enforced that you have to give back, which meant that the fragmentation has never been something that has been viable from a technical standpoint."

  • Making Use Of eBPF In The Mainline Linux Kernel

    One of the exciting innovations within the Linux kernel in the past few years has been extending the Berkeley Packet Filter (BPF) to become a more generalized in-kernel virtual machine. The eBPF work with recent versions of the Linux kernel allow it to be used by more than just networking so that these programs can be used for tracing, security, and more.

  • Linux turns 25 with a brilliant history

    Chances are, you use it every day. Linux runs every Android phone and tablet on Earth. And even if you’re on an iPhone or a Mac or a Windows machine, Linux is working behind the scenes, across the Internet, serving up most of the webpages you view and powering most of the apps you use. Facebook, Google, Pinterest, Wikipedia—it’s all running on Linux.

    Now, Linux is finding its way onto televisions, thermostats, and even cars. As software creeps into practically every aspect of our lives, so does the OS designed by Linus Torvalds.

  • Intel Lost Another Open-Source Driver Developer To Google Earlier This Summer

    There was another long-time Intel open-source Linux graphics driver developer that left the company earlier this summer and is now working at Google on the Chrome/Chromium OS graphics stack.

    Among the notable departures in the past few months from Intel's Open-Source Technology Center were Jesse Barnes, Wayland-founder Kristian Høgsberg, and Dirk Hohndel and apparently others that went under the radar or outside of our area of focus. Another graphics driver developer no longer at Intel is Chad Versace.

Distro Development: Rescatux and Bodhi

TuxMachines - Sat, 2016-08-27 21:24
  • Rescatux 0.40 beta 9 released

    Many code in the grub side and in the windows registry side has been rewritten so that these new features could be rewritten. As a consequence it will be easier to maintain Rescapp.

    Finally the chntpw based options which modify the Windows registry now perform a backup of the Windows registry files in the unlikely case you want to undo some of the changes that Rescapp performs.

    I guess that in the future there will be a feature to be able to restore such backups from Rescapp itself, but, let’s focus on releasing an stable release. It’s been a while since the last one.

    UEFI feedback is still welcome. Specially if the Debian installation disks work for you but not the Rescatux ones.

  • Bodhi 4.0.0 Updates and July Donation Totals

    Late last month I posted a first alpha look at Bodhi 4.0.0. Work since then has been coming along slowly due to a few unpredictable issues and my own work schedule outside of Bodhi being hectic over the summer. Bodhi 4.0.0 will be happening, but likely not with a stable release until September. I am traveling again this weekend, but am hoping to get out a full alpha release with 32bit and non-PAE discs next week.

Emma A LightWeight Database Management Tool For Linux

TuxMachines - Sat, 2016-08-27 21:07

Today who does not interact with databases and if you're a programmer then the database management is your daily task. For database management, there is a very popular tool called, MySQL Workbench. It's a tool that ships with tonnes of functionalities. But not all of us as beginner programmers use all Workbench features. So here we also have a very lightweight database manager in Linux, Emma.

Linux on Chromebooks with Bay Trail?

Reddit - Sat, 2016-08-27 20:54

So I was planning on buying a Chromebook for school and putting linux on it, but I read everywhere that with the Intel processors Bay Trail it often won't be possible.

Can anyone advice me on which brands/models indeed have problems with installing Ubuntu instead of ChromeOS or don't ?

What's the big deal with Linux vs GNU/Linux?

Reddit - Sat, 2016-08-27 20:05

I have seen a lot of info online about GNU and Linux, and this tends to be a slightly controversial topic around these parts with some people referring to a distribution as simply Linux vs some people adamantly describing it as GNU/Linux. I understand that Linux is the Kernal. What part does GNU actually play into a popular distribution like Fedora or Ubuntu and why do some people insist on GNU/Linux vs Linux? Aside from the GPL and some tools the OS uses, where does GNU fit into the whole Linux ecosystem?

Vale, LOGO creator Seymour Papert, who taught us that code can be creative play

LXer - Sat, 2016-08-27 19:12
Arduino-fiddling kids, and the rest of us, owe Papert a debt of gratitudeBack when dinosaurs ruled the Earth and I was a kid, I received the gift of a "100-in-1 Electronics Kit" that taught me the basics of electrical circuit design as I strung pre-cut wires between springy posts. At the very centre of this kit - its beating heart - a single transistor could be wired to work in an amplifier, or AM radio, or tone generator.…
