Video: A Different Linus talks about an Open CPU

Submitted by Scott Dowdle on Wed, 08/29/2018 - 09:37

We have had a few discussions about the RISC-V development (at the BozemanLUG meetings).  Some Fedora folks have gotten Linux working on some of the RISC-V development boards.  There appear to be several layers to the overall design from the low-end moving up.  Can RISC-V ever become a viable, mainstream alternative?  Time will tell... but at the very least, seeing such developments gives me some hope.  Here's a somewhat mainstream "youtuber" talking about RISC-V and given the number of views so far, maybe the word / information will break through.

Video: Raspberry Pi 3B+ on Pi Day

Submitted by Scott Dowdle on Thu, 03/15/2018 - 08:29

I'm sure everyone has already heard this from yesterday... but yes after believing there wouldn't be a new Raspberry Pi release for 2018 because nothing was announced at the end of Feb., the Raspberry Pi foundation pulled a fast one on Pi Day by announcing a new revision of the Raspberry Pi 3B.  They added a + to the end of it: Raspberry Pi 3B+.

What's new?  They improved power regulation and cooling of the CPU enabling a default clockrate 200MHz faster than the previous Pi (1.4GHz).  They totally refreshed the radio components (with a nice RPi logo stamped on the cover of it) bumping the wifi to dual-band 802.11ac and Blutooth 4.2.   They also improved ethernet performance making it "faster ethernet" but just under 1GBit along with 4 new pins for Power-over-Ethernet (PoE) capabilities with an add-on HAT.  Overall it is a cleaner design and the best Raspberry Pi to date.

While some had hoped for a doubling of the RAM (still only 1GB) that just wasn't in the cards as RAM prices have been significantly increasing over the last year and it is very important to the Raspberry Pi Foundation to keep the price point at $35.

Quite a few reviewers got a hold of the new model early and were able to post informative videos on YouTube including some benchmarks.  Retailers don't quite have them in stock yet but will RSN.  I already put in my order with Newark and it should be shipping in about 10 days.  I hope to get FedBerry going on mine for a desktop Fedora system.  I'll post about that when the time comes.  In the meantime, enjoy the following brief video mentioning what's new in the Raspberry Pi 3B+.

Update: My Rpi3B+ arrived on Monday, March 19th.  Wow, that was fast.  I couldn't find the case I had so I haven't had time to play with it yet.  For some reason, it seems smaller than previous models.

Video: LCA 2017 - Package Managers All the Way Down

Submitted by Scott Dowdle on Tue, 02/07/2017 - 14:28

Anyone who has been using Linux for a while is familiar with package managers and package management.  Being a Fedora user, I have noticed a few projects that Fedora has in the works to augment package management.  For example, Fedora Atomic does not the traditional package manager (dnf) but uses rpm-ostree instead.  Why would Fedora be working on additional packaging systems?  What is wrong with existing package managers?  I have been asking myself those questions for some time now.

Kristoffer Grönlund provides answers to those questions in a talk entitled, "Package Manages all the way down".  Enjoy.

Video: What's Next for Containers?

Red Hat's Vincent Batts gives a  presentation at systemd.conf 2016 conference entitled, "What's next for containers?".  It is a good overview of where the various container projects are (with no mention of OpenVZ however) and what work needs to be done.  I enjoyed his assessment that the first thing that is next is, "Get Past the Hype," and to, "Make Containers Boring."  Vincent goes over several of the userland tools as well as covers the areas where Linux native containers still need work.  Enjoy.

There have been a ton of conferences in the last couple of months... and luckily a lot of the presentations were recorded and have been posted.  Here is Lennart Poettering's presentation from the systemd.conf 2016 conference on, "State of the Union / Portable Services".  Enjoy.
