4 Linux and a BSD Distro every Sysadmin should have in their toolbox

Filed under
Linux

While as a Sysadmin our world is generally speaking goverend by Windows Desktops and servers, Microsoft's OS isn't the best one out there at every task, for some tasks Linux is the answer, I've written on other blogs on a similar topic, about Linux Distros and which ones you will get he most out of. The idea behind most of these Linux Distros is they act as a tool or a set of tools to perform a certain task.
Each one of thses distros is free, downloads as an ISO and can be run (apart from one) booted from a CD without installation.

Though I tend to stay away from publicly reviewing distributions that use the default GNOME 3 desktop, I evaluate them privately and if I come across one that has been modified to look like a true desktop operating system, then I will take the time to do what it takes to publish a review on it. Linux Deepin falls into that category. So expect a review of Linux Deepin soon.

The handheld console unit may very soon become a thing of the past and with games costing upwards of £50 their big brothers the home console unit may not be far behind. It's however pretty safe to say that the future of portable gaming on mobile phones hosting IOS and Android does have a very lucrative future.

A week with Sabayon on the Macbook Pro

Filed under
Linux

Last week after being desperatly disappointed with the direction Apple are taking with OSX after using Mountain Lion for a ew hour i decided to go back to using Linux. However finding the right Linux distro was important, the Macbook Pro (MBP) is not a PC, yes it will run almost every Intel based linux distro there are a few hardware gotchas which make the choice of Distro important for the quickest out of the box up and working experience.

As the title suggests a platform i'm already enamoured with was my first choice, the Gentoo based source and binary distro Sabayon with its recently updated version 8.

the announcement of Mountain Lion is the Vista moment for Apple, it's that point when many Apple users will take time to step back and think about the Operating system on their Apple PC.

Windows 8 will be one option However Linux has become a very stable OS when done right on Apple hardware. However it takes a big step and a leap of faith to drop OSX..

Observations of a Egotistical Technical Elitist

Lets be honest, the title alone sets the tone of this post, so please no comments stating i'm an elitist snob, because this i'm am keenly aware of. However a touch of honesty now and again does tend to go a long way.

So what's the problem? Well there are more than one and they grind me down on a daily basis, so it's time to air them here and these are all tech issues..

So lets start with...

Smartphones are computers, they have the same processing power as devices from a few years back, decent battery lives, complete Operating systems which will sit happily on desktop PC's if you let them. However when we get into the office or home, we put them down and head for the keyboard..

Ubuntu/Linux has a potentially big role to play in this arena if it does it right on Mobiles. A few standards are needed for Dock connectors so 3rd parties can join in and very soon true mobile computing could pave the way..

What the difference a distro release makes..

Filed under
Linux

I'm a firm believer in Sabayon, i've been using it since the heady days of version 3 with the DVD ISO which contained nearly 4GB of both Gnome and KDE distros and an hours installation. This gave the user a bleeding edge distro which implemented Compiz first and better than anyone else as an example.however I have to say I'm just a little disappointed in this release with it's implementation of Gnome 3.

Kernel Coverage at LWN (Outside Paywall Now)

  • XArray and the mainline
    The XArray data structure was the topic of the final filesystem track session at the 2018 Linux Storage, Filesystem, and Memory-Management Summit (LSFMM). XArray is a new API for the kernel's radix-tree data structure; the session was led by Matthew Wilcox, who created XArray. When asked by Dave Chinner if the session was intended to be a live review of the patches, Wilcox admitted with a grin that it might be "the only way to get a review on this damn patch set". In fact, the session was about the status of the patch set and its progress toward the mainline. Andrew Morton has taken the first eight cleanup patches, Wilcox said, which is great because there was a lot of churn there. The next set has a lot of churn as well, mostly due to renaming. The 15 patches after that actually implement XArray and apply it to the page cache. Those could be buggy, but they pass the radix-tree tests so, if they are, more tests are needed, he said.
  • Filesystem test suites
    While the 2018 Linux Storage, Filesystem, and Memory-Management Summit (LSFMM) filesystem track session was advertised as being a filesystem test suite "bakeoff", it actually focused on how to make the existing test suites more accessible. Kent Overstreet said that he has learned over the years that various filesystem developers have their own scripts for testing using QEMU and other tools. He and Ted Ts'o put the session together to try to share some of that information (and code) more widely. Most of the scripts and other code has not been polished or turned into a project, Overstreet continued. Bringing new people up to speed on the tests and how they are run takes time, but developers want to know how to run the tests before they send code to the maintainer.
  • Messiness in removing directories
    In the filesystem track at the 2018 Linux Storage, Filesystem, and Memory-Management Summit (LSFMM), Al Viro discussed some problems he has recently spotted in the implementation of rmdir(). He covered some of the history of that implementation and how things got to where they are now. He also described areas that needed to be checked because the problem may be present in different places in multiple filesystems. The fundamental problem is a race condition where operations can end up being performed on directories that have already been removed, which can lead to some rather "unpleasant" outcomes, Viro said. One warning, however: it was a difficult session to follow, with lots of gory details from deep inside the VFS, so it is quite possible that I have some (many?) of the details wrong here. Since LSFMM there has been no real discussion of the problem and its solution on the mailing lists that I have found.
  • Handling I/O errors in the kernel
    The kernel's handling of I/O errors was the topic of a discussion led by Matthew Wilcox at the 2018 Linux Storage, Filesystem, and Memory-Management Summit (LSFMM) in a combined storage and filesystem track session. At the start, he asked: "how is our error handling and what do we plan to do about it?" That led to a discussion between the developers present on the kinds of errors that can occur and on ways to handle them. Jeff Layton said that one basic problem occurs when there is an error during writeback; an application can read the block where the error occurred and get the old data without any kind of error. If the error was transient, data is lost. And if it is a permanent error, different filesystems handle it differently, which he thinks is a problem. Dave Chinner said that in order to have consistent behavior across filesystems, there needs to be a definition of what that behavior should be. There is a need to distinguish between transient and permanent failures and to create a taxonomy of how to deal with each type.
  • 4.18 Merge window, part 1
    As of this writing, 7,515 non-merge changesets have been pulled into the mainline repository for the 4.18 merge window. Things are clearly off to a strong start. The changes pulled this time around include more than the usual number of interesting new features; read on for the details.
  • Year-2038 work in 4.18
    We now have less than 20 years to wait until the time_t value used on 32-bit systems will overflow and create time-related mayhem across the planet. The grand plan for solving this problem was posted over three years ago now; progress since then has seemed slow. But quite a bit of work has happened deep inside the kernel and, in 4.18, some of the first work that will be visible to user space has been merged. The year-2038 problem is not yet solved, but things are moving in that direction. If 32-bit systems are to be able to handle times after January 2038, they will need to switch to a 64-bit version of the time_t type; the kernel will obviously need to support applications using that new type. Doing so in a way that doesn't break existing applications is going to require some careful work, though. In particular, the kernel must be able to successfully run a system where applications have been rebuilt to use a 64-bit time_t, but ancient binaries stuck on 32-bit time_t still exist; both applications should continue to work (though the old code may fail to handle times correctly). The first step is to recognize that most architectures already have support for applications running in both 64-bit and 32-bit modes in the form of the compatibility code used to run 32-bit applications on 64-bit systems. At some point, all systems will be 64-bit systems when it comes to time handling, so it makes sense to use the compatibility calls for older applications even on 32-bit systems. To that end, with 4.18, work has been done to allow both 32-bit and 64-bit versions of the time-related system calls to be built on all architectures. The CONFIG_64BIT_TIME configuration symbol controls the building of the 64-bit versions on 32-bit systems, while CONFIG_COMPAT_32BIT_TIME controls the 32-bit versions.
