At KubeCon + CloudNativeCon Europe 2019 there was a public meeting of the Cloud Native Computing Foundation (CNCF) Technical Oversight Committee (TOC); its members outlined the current state of the CNCF and where things are headed. What emerged was a picture of how the CNCF's governance is evolving as it brings in more projects, launches a new special interest group mechanism, and contemplates what to do with projects that go dormant.

As we've been expecting, AMD's open-source developers today posted their set of patches enabling Navi (10) support within their AMDGPU DRM kernel driver. Bringing up the Navi support in kernel-space are 459 patches amounting to more than four-hundred thousand lines of code, not counting the work done to LLVM as part of their shader compiler back-end or the yet-to-be-published OpenGL/Vulkan driver patches...

Spanish Linux computer company Slimbook has unveiled its brand new all-in-one “Apollo” Linux PC — and it looks… Well, it looks familiar.

The Apollo AIO swaps the curved screen of its immediate predecessor for a 23.6-inch IPS LED display running at a decent 1920×1080 resolution. The screen is apparently a “crystal coated panel” that improves the appearance of colours.

Internally, the AIO is configurable according to needs. There’s a choice of Intel i5-8500 and Intel i7-8700 processor, up to 32GB RAM, integrated Intel UHD 630 4K graphics, and a veritable smorgasbord of storage options.

Canonical announced Ubuntu snaps support for DJI’s second-gen Manifold companion computer for its Matrice drones. The Manifold 2 offers a choice of Jetson TX2 or Intel Coffee Lake-U chips.

DJI’s industry leading drones such as its Phantom and Matrice models are directed by flight controllers that run a proprietary operating system. Yet, in 2015, the company announced a Manifold development computer for its Matrice 100 drone that runs Ubuntu on an Nvidia Tegra K1. A few weeks ago, DJI unveiled a more powerful Manifold 2 computer with a choice of Nvidia Jetson TX2 and Intel Core i7-8550U processors (see farther below). Canonical has followed up by announcing that not only will Ubuntu 16.04 return as the pre-installed OS for the device, but that it will include support for Ubuntu snaps application packages.

• Linux 5.3 Could Finally See FSGSBASE - Performance Improvements Back To Ivybridge

  The FSGSBASE instruction set has been present on Intel processors going back to Ivy Bridge processors and while there have been Linux kernel patches for this feature going on for years, it looks like with the Linux 5.3 kernel cycle is this support for merging. Making us eager for this support is the prospect of better performance, especially for context switching workloads that already have been suffering as a result of recent CPU mitigations. 

  The FSGSBASE instructions allow for reading/writing FS/GS BASE from any privilege. But the short story is there should be performance benefits from FSGSBASE in context switching thanks to skipping an MSR write for GSBASE. User-space programs like Java are also expected to benefit in being able to avoid system calls for editing the FS/GS BASE.

• Security updates for Monday

  Security updates have been issued by Arch Linux (chromium and thunderbird), Debian (php-horde-form, pyxdg, thunderbird, and znc), Fedora (containernetworking-plugins, mediawiki, and podman), openSUSE (chromium), Red Hat (bind, chromium-browser, and flash-plugin), SUSE (docker, glibc, gstreamer-0_10-plugins-base, gstreamer-plugins-base, postgresql10, sqlite3, and thunderbird), and Ubuntu (firefox).

• Self-Audits | Roadmap to Securing Your Infrastructure

  As you can see, the security audit can be tailored based on any security controls you have/need. NIST provides the 800-53A (“A” is for audit or assessment) and provides different file formats to use. This is a great place to start creating your own audit document.

  To sum it up, embracing self-audits and the benefit they provide will reduce risk and save time. The longer a security control remains in a failed state, the more time threats have to exploit a vulnerability. Protect yourself and add security by prioritizing audits.

Samsung pravi, da virusi prežijo tudi na pametne televizorje

• Matej Huš :: včeraj ob 20:13
• Zasloni / projektorji / ...

Slo-Tech - Ko so televizorji dobili pamet in povezavo v splet, so postali tudi privlačna tarča za viruse in drugo nesnago. Če k temu dodamo še dejstvo, da imajo nekateri moderni televizorji tudi kamero in mikrofon, gre razumeti najnovejše Samsungovo svarilo. Podjetje je namreč na Twitterju zapisalo, da je redno preverjanje pametnih televizorjev QLED za okužbe z virusi enako pomembno kot pri računalnikih, če so televizorji priključeni na Wi-Fi. Svetujejo, da preventivno zaženemo antivirusni program vsakih nekaj tednov, priložen pa je tudi videoposnetek. Več na Slo-Techu.

Ker ameriška in tudi nekatere druga podjetja odpovedujejo sodelovanje s Huaweijem, so se Kitajci začeli pripravljati na najhujši scenarij. Kot kaže, jim ne bo uspelo pravočasno zamenjati dobaviteljev. Več na Slo-Techu.

• NetworkManager Now Supports Making OVS DPDK Interfaces, Other Work For 1.20

  NetworkManager 1.19.4 is the newest snapshot of this widely used Linux networking library on its road to version 1.20.

  NetworkManager 1.19.4 was tagged last week as the latest stepping stone towards the NetworkManager 1.20 stable release. A new feature also making it into NM this past week was support for creating OVS DPDK interfaces -- that's the Open vSwitch Data Plane Development Kit. Open vSwitch's DPDK path allows for lower-latency and higher-performance connectivity between OpenStack compute node instances and now with NetworkManager 1.20 is this better OVS-DPDK integration.

• 4 best browsers that don't save your history and personal data [Ed: Microsoft Windows advocacy sites cannot recommend Microsoft anything for privacy]

  Tor is another great browser heavily focused on user privacy and security. It’s available for Windows, MacOS, and GNU/Linux in 32-bit and 64-bit versions that are constantly updated.

  Its main focus is on anonymity. Based on a modified Firefox ESR, it contains things like NoScript and HTTPS-Everywhere.

  The browser works in a network that promises to protect a user‘s browsing history, location, messages, and any online personal data from people or bots that perform network traffic analysis.

  Tor network is a web of servers operated by volunteers. Their aim is to keep browsing data as secure as it can be. With Tor, you don’t have to worry about browsing history, saved passwords or auto-completion data.

  Also, it’s worth mentioning that Tor is the only browser that uses onion services. This means that users can publish websites and other services without revealing the location.

• Substitutes are now available as lzip

  For a long time, our build farm at ci.guix.gnu.org has been delivering substitutes (pre-built binaries) compressed with gzip. Gzip was never the best choice in terms of compression ratio, but it was a reasonable and convenient choice: it’s rock-solid, and zlib made it easy for us to have Guile bindings to perform in-process compression in our multi-threaded guix publish server.

  With the exception of building software from source, downloads take the most time of Guix package upgrades. If users can download less, upgrades become faster, and happiness ensues. Time has come to improve on this, and starting from early June, Guix can publish and fetch lzip-compressed substitutes, in addition to gzip.

• Enhanced OpenShift Red Hat AMQ Broker container image for monitoring

  Previously, I blogged about how to enhance your JBoss AMQ 6 container image for production: I explained how to externalise configuration and add Prometheus monitoring. While I already covered the topic well, I had to deal with this topic for version 7.2 of Red Hat AMQ Broker recently, and as things have slightly changed for this new release, I think it deserves an updated blog post!

  This post is a walk-through on how to enhance the base Red Hat AMQ Broker container image to add monitoring. This time we’ll see how much easier it is to provide customizations, even without writing a new Dockerfile. We will even go a step further by providing a Grafana dashboard sample for visualising the broker metrics.

• New Style Signal/Slot Connection

  Yes, I know. The last post on the assistants is rather boring. And yet these days I have been working on the snapshot docker, though it still seems a little (just a little, you see) unfinished as Dmitry is said to experience a relatively high delay when switching between snapshots. However this is not what I can reproduce on my older laptop, so I am really waiting for his test results in order to further investigate the problem.

  But there is something interesting happening just when I am randomly testing things. From Krita’s debug output, I saw QObject::connect() complaining about the arguments I passed, saying it is expecting parenthesis. “Okay,” I thought, “then there have to be something wrong with the code I wrote.” And that was quite confusing. I remember having used member function pointers in those places, got a compile-time error since KisSignalAutoConnectionsStore did not support the new syntax, then switched back to the SINGAL() and SLOT() macros. KisSignalAutoConnectionsStore is a helper class to quickly (dis)connect a group of connections. One can use the addConnection() method to add a connection, and use clear() to remove all connections made before.

  Well, everything good, apart from the fact that I missed the parenthesis, which I did not discover until I looked into the debug output. So I asked Dmitry why not add the new syntax to KisSignalAutoConnectionsStore, and he said we should.

Ameriška vojska postaja informacijsko agresivnejša

• Dare Hriberšek :: včeraj ob 19:12
• NWO

vir: The New York TimesThe New York Times - Poveljstvo za informacijsko vojskovanje ameriške vojske je v zadnjem letu postalo precej bolj agresivno do Rusije, kot kdajkoli doslej, je ta konec tedna poročal New York Times. Tako naj bi v rusko elektro omrežje uspešno namestili zlobno kodo, potem, ko jim je prehod iz defenzivnega v ofenzivno delovanje - če to zahteva odvračanje ali obramba pred informacijskimi napadi na ZDA - lani poleti odobril tamkajšnji Kongres. Za tako delovanje vojske niti ni več potrebna odobritev predsednika, pač pa zadostuje podpis obrambnega ministra. Več na Slo-Techu.
