Acer Chromebook 15 for Linux and Wimbledon

Filed under
Reviews

Earlier this month my husband and I needed a replacement for the Chromebook that I had installed Linux on after Christmas because the keyboard developed a fault. This was a good opportunity to get an upgrade and to connect the 28-inch monitor to it, allowing us to watch Wimbledon over the Internet (we don't watch TV).

Unboxing photos:

Setting up the machine:

It comes with Chrome OS, but I don't want that:

Switch to developer mode:

Setting it up to not be so locked down:

With Roy's help, installing Ubuntu LTS:

Nearly done:

Running KDE/Plasma (my favourite):

Running XFCE:

Running Unity (which I still try to use on a daily basis after using KDE for years):

We have since then bought a cabinet for the external screen and Roy finished building it 2 days ago, so now we can watch shows while we work (4 screen combined using Synergy).

I installed Ubuntu on it as my default OS, though I can go back to Chrome OS any time I want. I don't see any point in doing it.

Roy helped me do the partitioning, configuration and tweaking. We configure it in a way so that I can use it in my work, not just for Facebooking, tweeting and chatting's sake.

I am still exploring the machine, basically familiarising with the keyboard and all the function settings on it. The Kubuntu environment which I chose will need some adjustments; also the applications which I downloaded are a bit different from the other laptop's (which I used to work on).

HP Chromebook 14

Change is good, but it requires a lot of patience and adaptation to the new environment.

HP Chromebook 14

I like my Chromebook very much. It is one of the best gifts I have received from my husband. It is more practical, it gives me more confidence to learn and to develop more of my computer skills. Innovation is fast-moving and technology is progressing, so you definitely need to catch up with it. Unless you want to be left behind by choice...

Is Nokia Really Dying?

Filed under

Telephone

It was almost two months ago that I wrote about Nokia's most-awaited comeback, for the new designs and innovation of their mobile phones, but it did not happen. In fact, Nokia's ordeal became worse because Nokia is dying. Yes! Nokia is dying as Microsoft once again used their power 'trick' to get a stranglehold on the most influential and trusted company when it comes to innovation and technology. No matter what changes and what Microsoft is doing, there will be no difference. Chances are, only the features and profiles have changed, but the personal interest and infrastructure most likely are the same or even worse than that. Now Nokia has become the new platform of surveillance, it will never be the same again. The trust has been tarnished, the public has become more aware of Microsoft's anomalies and all sorts of devil's advocate games. Doing business with Microsoft is a big mistake. Take Nokia's example. I hope Android and Tizen will not consider deals or any tie-ups with Microsoft, and to all the rest who support and advocate open source, rest assured that FOSS will prevail.

XBMCbuntu Eden on the ASRock 330

The latest release of XBMC my preferred application for viewing my Movie collection on the TV and there has been an updated release just recently. I was urged to give this a whirl as it has an Apple Airplay server built in for streaming video on the TV from the iPad.

I have been running XBMC 10.0 on a Sabayon system for the past few months and it's beeen running well, however always one for the new and change I wanted to give XBMC 11 a bit of a go. The first stage was to see if the Sabayon repositories had an update, they did however it wasn't to the release version it was to the release candidate 2. This doesn't include the airplay functionality so an alternative was needed.

  • 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

Red Hat and SUSE Leftovers

  • 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.
