Graphics/Benchmarks
Ubuntu

The Ibex Pro is one supercharged machine that will probably hurt your electric bill.

System76's fastest Ibex Pro with Ubuntu Server 16.10 packs some crazy horsepower with Intel's latest 22-core Xeon E5 v4 chips and eight Nvidia Tesla P100 graphics processors.

It's got the same number of GPUs as Nvidia's superfast DGX-1, which is being used for deep learning. System76 is targeting the Ibex Pro -- which is a rack server -- at the same market as the DGX-1. The server has fewer, but newer, CPUs, compared to the DGX-1.

  • You're taking the p... Linux encryption app Cryptkeeper has universal password: 'p'

    Linux encryption app Cryptkeeper has a bug that causes it to use a single-letter universal decryption password: "p".

    The flawed version is in Debian 9 (Stretch), currently in testing, but not in Debian 8 (Jessie). The bug appears to be a result of a bad interaction with the encfs encrypted filesystem's command line interface: Cryptkeeper invokes encfs and attempts to enter paranoia mode with a simulated 'p' keypress – instead, it sets passwords for folders to just that letter.

  • Reproducible Builds: week 92 in Stretch cycle

    John Gilmore wrote an interesting mail about how Cygnus.com worked on reproducible builds in the early 1990s. (It's eye opening to see how the dealt with basically the very same problems we're dealing with today, how they solved them and then to realize that most of this has been forgotten and bit-rotted in the last 20 years. How will we prevent history repeating it)self here?)

  • MongoDB ransom attacks continue to plague administrators

    Earlier this month, Salted Hash reported on a surge in attacks against publicly accessible MongoDB installations.

    Since January 3, the day of that first report, the number of victims has climbed from about 200 databases to more than 40,000. In addition to MongoDB, those responsible for the attacks have started targeting Elasticsearch and CouchDB.

    No matter the platform being targeted, the message to the victim is the same; send a small Bitcoin payment to the listed address, or forever lose access to your files.

  • Developing open leaders

    For many people, that requires a profound mindset shift in how to think about leaders. Yet in some ways, it's what we all intuitively know about how organizations really work. As Red Hat CEO Jim Whitehurst has pointed out, in any organization, you have the thermometers—people who reflect the organizational "temperature" and sentiment and direction—and then you have the thermostats—people who set those things for the organization.

  • ​Monash University gets multi-petabyte computing boost from Red Hat, Dell EMC

    Monash University has implemented a multi-petabyte deployment at its eResearch Centre, giving the Melbourne-based advanced computing facility the capacity to store and manage massive workloads of data.

    The university implemented a software-defined solution that uses Red Hat Ceph Storage on Dell EMC PowerEdge R630 and R730xd rack servers that it expects will accelerate application performance, simplify systems management, and address the university's growing data storage requirements.

  • Deliverable 1 : [✓]
    Seems okay, far better than the initial results. Although I should say, I deviated from what I thought I would need to write. First I assumed that I don’t have to write another boost::graph wrapper for KisPaintDevice, but I had to. That was one heck of an experience. In one of the last few posts, I ranted on Dmitry’s interpretation of the Graph, turns out we were on the same page but I understood his explanation the wrong way. I should put more attention to details from now on I guess. All the pixels are connected to each other, but they only have an edge between them if they are adjacent. If in center, the out degree would be 8, if in corners, 3 and if in edges, 5. There are some other cases too, but I will leave them for the moment. While writing the wrapper, I also got to know some of the cool features and techniques of C++, which I will be writing posts on as soon as I get some time, concepts, traits, avoiding virtual functions and what not. It is commendable that how boost approaches boost::astar_search, there is not a single virtual function, you don’t have to inherit anything (you can though for safety), just templates and traits, you are done.
  • Go Creeping In
    I’ve seen the inside of the Google and Amazon tech stacks. There are common threads that run through them and also, I bet, through most BigTechCos. Here and there down the stack is a lot of C++ and vestigial remnants from earlier days, Perl or PHP or whatever. Out in front of humans, of course, JS. But in between, there are oceans and oceans of Java; to a remarkable degree, it runs the Internet. Except for, here and there, you find a small but steadily increasing proportion of Go.
  • Stand by for FPR14 SPR1 chemspill
    Mozilla has shipped a fix for MFSA2019-18 in Firefox 67.0.3 and 60.7.1. This exploit has been detected in the wild, and while my analysis indicates it would require a PowerPC-specific attack to be exploitable in official TenFourFox builds (the Intel versions may be directly exploited, however), it could probably cause drive-by crashes and we should therefore ship an urgent fix as well. The chemspill is currently undergoing confidence tests and I'm shooting to release builds before the weekend. For builders, the only change in FPR14 SPR1 is the patch for bug 1544386, which I will be pushing to the repo just as soon as I have confirmed the fix causes no regressions.

All Linux, all the time: Supercomputers Top 500

Starting at the top, two IBM-built supercomputers, Summit and Sierra, at the Department of Energy's Oak Ridge National Laboratory (ORNL) in Tennessee and Lawrence Livermore National Laboratory in California, respectively to the bottom -- a Lenovo Xeon-powered box in China -- all of them run Linux. Linux supports more hardware architectures than any other operating system. In supercomputers, it supports both clusters, such as Summit and Sierra, the most common architecture, and Massively Parallel Processing (MPP), which is used by the number three computer Sunway TaihuLight. When it comes to high-performance computing (HPC), Intel dominates the TOP500 by providing processing power to 95.6% of all systems included on the list. That said, IBM's POWER powers the fastest supercomputers. One supercomputer works its high-speed magic with Arm processors: Sandia Labs' Astra, an HPE design, which uses over 130-thousand Cavium ThunderX2 cores. And, what do all these processors run? Linux, of course. . 133 systems of the Top 500 supercomputers are using either accelerator or co-processor setups. Of these most are using Nvidia GPUs. And, once more, it's Linux conducting the hardware in a symphony of speed. Read more

  • Are DevOps certifications valuable? 10 pros and cons
  • Kubernetes 1.15: Enabling the Workloads
    The last mile for any enterprise IT system is the application. In order to enable those applications to function properly, an entire ecosystem of services, APIs, databases and edge servers must exist. As Carl Sagan once said, “If you wish to make an apple pie from scratch, you must first invent the universe.” To create that IT universe, however, we must have control over its elements. In the Kubernetes universe, the individual solar systems and planets are now Operators, and the fundamental laws of that universe have solidified to the point where civilizations can grow and take root. Discarding the metaphor, we can see this in the introduction of Object Count Quota Support For Custom Resources. In English, this enables administrators to count and limit the number of Kubernetes resources across the broader ecosystem in a given cluster. This means services like Knative, Istio, and even Operators like the CrunchyData PostgreSQL Operator, the MongoDB Operator or the Redis Operator can be controlled via quota using the same mechanisms that standard Kubernetes resources have enjoyed for many releases. That’s great for developers, who can now be limited by certain expectations. It would not benefit the cluster for a bad bit of code to create 30 new PostgreSQL clusters because someone forgot to add a “;” at the end of a line. Call them “guardrails” that protect against unbounded object growth in your etcd database.
  • Red Hat named HPE’s Partner of the Year at HPE Discover 2019
    For more than 19 years, Red Hat has collaborated with HPE to develop, deliver and support trusted solutions that can create value and fuel transformation for customers. Our work together has grown over these nearly two decades and our solutions now include Linux, containers and telecommunications technologies, to name just a few.

  • Demystifying Containers – Part II: Container Runtimes
    This series of blog posts and corresponding talks aims to provide you with a pragmatic view on containers from a historic perspective. Together we will discover modern cloud architectures layer by layer, which means we will start at the Linux Kernel level and end up at writing our own secure cloud native applications. Simple examples paired with the historic background will guide you from the beginning with a minimal Linux environment up to crafting secure containers, which fit perfectly into todays’ and futures’ orchestration world. In the end it should be much easier to understand how features within the Linux kernel, container tools, runtimes, software defined networks and orchestration software like Kubernetes are designed and how they work under the hood.
  • Edge > Core > Cloud: Transform the Way You Want
