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).

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?

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.

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.

Top 20 Uses of Linux

The Linux OS and its related distros and flavors have transformed it from hardcore software into an industrial brand. Even if you are not a fan of it, the Linux OS might be as common as the air you breathe if you closely analyze your day to day interactive activities. Almost all the modern technologies that transform and innovate the tech industry have a Linux OS DNA imprinted on them. Those that are yet to be branded with their innovative uniqueness and recognition are waiting in line for the famed chance. Therefore, you might boldly claim that the Linux OS does not run your life, but the world around you cannot avoid the flirty pursuits of this open-source and free software. Nowadays, almost anything that can be described as cool is either pursuing Linux or is being pursued by Linux. It is the perfect symbiotic relationship in a world that tries to find a balance in technology and innovation. This article explores the awesomeness and outreach of the Linux OS in the world around us. It might even be an eye-opener for some of us to start taking our Linux skills to the next level. Top500 quotes Linux as the powerhouse or engine behind five-hundred fastest computers worldwide. I do not know of the speed of the computer composing this article or whether it qualifies to be among the listed five-hundred fastest computers worldwide. However, one thing is certain; it is 100% Linux DNA. On this note, let us start parading the top 20 uses of Linux. Read more

Kernel: LWN's Latest and IO_uring Patches

  • Resource limits in user namespaces

    User namespaces provide a number of interesting challenges for the kernel. They give a user the illusion of owning the system, but must still operate within the restrictions that apply outside of the namespace. Resource limits represent one type of restriction that, it seems, is proving too restrictive for some users. This patch set from Alexey Gladkov attempts to address the problem by way of a not-entirely-obvious approach. Consider the following use case, as stated in the patch series. Some user wants to run a service that is known not to fork within a container. As a way of constraining that service, the user sets the resource limit for the number of processes to one, explicitly preventing the process from forking. That limit is global, though, so if this user tries to run two containers with that service, the second one will exceed the limit and fail to start. As a result, our user becomes depressed and considers a career change to goat farming. Clearly, what is needed is a way to make at least some resource limits apply on per-container basis; then each container could run its service with the process limit set to one and everybody will be happy (except perhaps the goats).

  • Fast commits for ext4

    The Linux 5.10 release included a change that is expected to significantly increase the performance of the ext4 filesystem; it goes by the name "fast commits" and introduces a new, lighter-weight journaling method. Let us look into how the feature works, who can benefit from it, and when its use may be appropriate. Ext4 is a journaling filesystem, designed to ensure that filesystem structures appear consistent on disk at all times. A single filesystem operation (from the user's point of view) may require multiple changes in the filesystem, which will only be coherent after all of those changes are present on the disk. If a power failure or a system crash happens in the middle of those operations, corruption of the data and filesystem structure (including unrelated files) is possible. Journaling prevents corruption by maintaining a log of transactions in a separate journal on disk. In case of a power failure, the recovery procedure can replay the journal and restore the filesystem to a consistent state. The ext4 journal includes the metadata changes associated with an operation, but not necessarily the related data changes. Mount options can be used to select one of three journaling modes, as described in the ext4 kernel documentation. data=ordered, the default, causes ext4 to write all data before committing the associated metadata to the journal. It does not put the data itself into the journal. The data=journal option, instead, causes all data to be written to the journal before it is put into the main filesystem; as a side effect, it disables delayed allocation and direct-I/O support. Finally, data=writeback relaxes the constraints, allowing data to be written to the filesystem after the metadata has been committed to the journal. Another important ext4 feature is delayed allocation, where the filesystem defers the allocation of blocks on disk for data written by applications until that data is actually written to disk. The idea is to wait until the application finishes its operations on the file, then allocate the actual number of data blocks needed on the disk at once. This optimization limits unneeded operations related to short-lived, small files, batches large writes, and helps ensure that data space is allocated contiguously. On the other hand, the writing of data to disk might be delayed (with the default settings) by a minute or so. In the default data=ordered mode, where the journal entry is written only after flushing all pending data, delayed allocation might thus delay the writing of the journal. To assure data is actually written to disk, applications use the fsync() or fdatasync() system calls, causing the data (and the journal) to be written immediately.

  • MAINTAINERS truth and fiction

    Since the release of the 5.5 kernel in January 2020, there have been almost 87,000 patches from just short of 4,600 developers merged into the mainline repository. Reviewing all of those patches would be a tall order for even the most prolific of kernel developers, so decisions on patch acceptance are delegated to a long list of subsystem maintainers, each of whom takes partial or full responsibility for a specific portion of the kernel. These maintainers are documented in a file called, surprisingly, MAINTAINERS. But the MAINTAINERS file, too, must be maintained; how well does it reflect reality? The MAINTAINERS file doesn't exist just to give credit to maintainers; developers make use of it to know where to send patches. The get_maintainer.pl script automates this process by looking at the files modified by a patch and generating a list of email addresses to send it to. Given that misinformation in this file can send patches astray, one would expect it to be kept up-to-date. Recently, your editor received a suggestion from Jakub Kicinski that there may be insights to be gleaned from comparing MAINTAINERS entries against activity in the real world. A bit of Python bashing later, a new analysis script was born.

  • Experimental Patches Allow For New Ioctls To Be Built Over IO_uring

    IO_uring continues to be one of the most exciting technical innovations in the Linux kernel in recent years not only for more performant I/O but also opening up other doors for new Linux innovations. IO_uring has continued adding features since being mainlined in 2019 and now the newest proposed feature is the ability to build new ioctls / kernel interfaces atop IO_uring. The idea of supporting kernel ioctls over IO_uring has been brought up in the past and today lead IO_uring developer Jens Axboe sent out his initial patches. These initial patches are considered experimental and sent out as "request for comments" - they provide the infrastructure to provide a file private command type with IO_uring handling the passing of the arbitrary data.
