Getting started with Go

Filed under

That history starts with C. In many ways, C is the Latin of programming languages. It inspired JavaScript, Ruby, Python, C++, C#, and Java. A few of those languages are even written in C. It's easy to spot C's influence by looking at if/else and control flow statements in any of the aforementioned languages. C was originally Dennis Ritchie and was used to build Unix. From there, C found its way to the heart of Linux, where C has continued to be the language of choice.

Go was created by legends from this Unix and C era. While working at Google, Robert Griesemer, Rob Pike, and Ken Thompson found themselves frustrated by the common pitfalls of C-family languages. As Bjarne Stroustroup, creator of C++ puts it: "C makes it easy to shoot yourself in the foot; C++ makes it harder, but when you do it blows your whole leg off."

    Arne Exton is informing Softpedia about the availability of a new build of his commercial RaspAnd Android-based operating system for embedded devices, such as Raspberry Pi 3 and Raspberry Pi 2.

    Still based on Google's Android 7.1.2 "Nougat" mobile operating system, RaspAnd Nougat 7.1.2 Build 170605 is here to replace last month's RaspAnd Nougat 7.1.2 Build 170519 release by upgrading Kodi Media Center to version 17.3, which is the latest in the series patching a nasty vulnerability known as the "subtitle hack."

    RaspAnd Nougat 7.1.2 Build 170605 also comes pre-installed with various updated apps, among which we can mention Spotify TV 1.2.0, Rotation Control Pro 1.1.2, Google Play Games 3.9.08, Clash of Clans 9.24.9, Gmail 7.4.23, and Aptoide TV 3.2.1.

Software Releases: The New and the Slightly Older

Tanglu 4 (Dasyatis kuhlii) released!

Filed under

This release took exceptionally long to complete, and we apologize for that. Tanglu 4 has been ready and sitting in the pipeline for months, but we did not have enough manpower to handle the last mile of the release process, especially due to our project leader being busy with work on another Debian derivative for Purism, a company that builds security-focused Linux-based computers.

Due to that experience with the Dasyatis release, we will make a couple of changes to how we develop Tanglu. No final decision has been made on any of the changes yet, but it looks like we will transform Tanglu into having one continuously updated rolling-release branch where fresh new stuff is added and the main development happens, and one stable release tracking the last respective Debian stable release. That way, the distribution will become much easier to maintain for a small team (a rolling-release branch requires less manpower to maintain). By aligning our stable releases with Debian, we will also greatly reduce the maintenance cost of stable releases by benefiting from Debian's security support. Of course, those stable releases will have all the Tanglu modifications, and will likely be directly branched off the rolling release track. This means that there will be one stable Tanglu release per stable Debian release, and a continuously updated rolling Tanglu release for people who like to have the latest and greatest software and maybe participate in Tanglu development.

GNOME Tracker 2.0 and United GNOME

  • Plans In The Works For GNOME Tracker 2.0

    Version 2.0 is the next major release of GNOME's Tracker software for file meta-data indexing and searching.

  • Next Tracker is 2.0.0

    Tracker is usually deemed a “metadata indexer”, although that’s just half the truth. Even though Tracker could be essentially considered that in its very early days, it made a bold move back in 0.7.x to using Sparql as the interface to store and retrieve this metadata, where both the indexers and the applications using this metadata talk the same language.

  • United GNOME – A Unity 8-Inspired Theme for the GNOME Shell

    When United GNOME theme first came out I didn’t write about it because in as much as it was inspired by a concept of Ubuntu 18.04’s now-scrapped Unity 8 desktop, it was more buggy than I could stand.

    Thanks to a recent update, the theme has come to see many changes and UI tweaks which overall make it better than at its initial release. Now, I can tell you about it.

Parrot Security OS Ethical Hacking Distro Considers Ditching Debian for Devuan

Filed under

The development team behind the Parrot Security OS ethical hacking and security-oriented GNU/Linux distribution announced that they are considering a possible switch from Debian GNU/Linux to Devuan GNU/Linux as the base of the OS.

The surprising announcement came was posted a couple of days ago on Twitter, and it reads "Our release team is evaluating a possible migration of our project from Debian to Devuan." A few users reacted negatively to the idea of moving the entire operating system from Debian to Devuan, a fork of the former, but without using systemd.

  • Linux 4.12-rc5

    Oh well, the "all the rc's have been nice and small this release
    around" thing definitely didn't continue all the way.

    It's not like rc5 is *huge*, but it definitely isn't the nice and
    small one I was hoping for. There's nothing in partiocular that looks
    very worrisome, and it may well just be random timing - the rc sizes
    do fluctuate a lot depending on just which subsystem gets synced up
    that particular rc, and we may just have hit that "everybody happened
    to sync up this week" case.

    Anyway, rc5 is our biggest rc this release (obviously not counting
    rc1, which contains all of the the merge window). And it definitely
    does have stuff all over: we've got driver updates (gpu, networking,
    scsi, block layer and sound are the biggest, but there's stuff all
    over), we've got arch updates (arm[64], powerpc, sparc, x86), and
    we've got filesystems (btrfs, ext4, and unusually several ufs fixes
    thanks to recent bug reporting activity).

    But we _also_ have various documentation yupdates, generic networking,
    some key handling fixes, and perf and kvm fixes.

    So it really isn't one thing, it's just a lot of different small stuff.

    And it's not like it's actually unreasonably big, it mainly stands out
    because the 4.12 release cycle so far has been fairly calm.

    Anyway, I really hope this was just a random timing fluke. Partly I
    hope that because of just general wishes for releases to calm down,
    but in particular I will be traveling the next week+, and while I'll
    have internet and my trusty laptop, I was hoping that things would be
    calm while I'm off gallivanting around the world.

    Of course, maybe it will be extra calm exactly _because_ people got
    their patches out of the way. I can hope.

    Anyway, go out and test,


  • Linux 4.12-rc5 Released: The Biggest RC This Cycle

    Linus Torvalds has released the Linux 4.12-rc5 kernel as the fifth weekly test candidate for what will become Linux 4.12 stable later this month.

  • Linus Torvalds Announces the Fifth Release Candidate of Linux 4.12 Kernel Series

    Being Sunday evening and all that, Linus Torvalds just made its regular announcement a few moments ago informing the community about the release of the fifth RC (Release Candidate) milestone of the upcoming Linux 4.12 kernel series.

    Linux kernel 4.12 RC5 does not follow in the footsteps of last week's Release Candidate 4 milestone, nor any of the other previous RCs and appears to a slightly bigger patch that adds numerous updated drivers, especially GPU, SCSI, networking, sound, and block layer ones, various improvements for the ARM, ARM64 (AArch64), x86, SPARC and PPC (PowerPC) hadware architectures, and updates to the Btrfs, EXT4 and UFS filesystems.

  • Coming off a strong quarter, Red Hat CEO Jim Whitehurst talks public clouds and containers
    Coming off a quarterly earnings report that shattered expectations, Red Hat CEO Jim Whitehurst believes his company is as well-positioned to capitalize on the shift to cloud computing as it ever has been. Red Hat is in a very interesting place in 2017, with one foot in two different eras of enterprise computing but thriving in that position instead of feeling trapped. It still makes most of its money selling Red Hat Enterprise Linux to companies running their own data centers, but it has become the de facto leader of the OpenStack cloud computing project and has interesting DevOps products in Ansible (IT automation) and OpenShift (container management). On Tuesday, the company reported a 19 percent increase in both revenue and net income to $677 million and $73 million, respectively, during its first fiscal quarter of the year. Financial analysts, who peppered Whitehurst with more than their usual share of “Great quarter!” asides during a conference call, were expecting revenue of $648 million according to Marketwatch. The company also raised revenue guidance for its full fiscal year.

The work on the automatic updater has been going on for nearly a year now and is finally in a shape that we produce builds on TDF hardware that will automatically update using delta updates. The current builds are 64-bit Linux builds created on SLES 12.2 and should run on most Linux distros. These builds are .tar.gz based archives that you can extract and just run. Note that we can’t update builds that are placed into locations that are not writeable by the current user (and due to missing support for signing executables and libraries on Linux there are no plans to change that).

The PostgreSQL community will find a lot to get excited about in this release, as the project has delivered a long list of enhancements to existing functionality. There's also a few features aimed at fulfilling new use cases, particularly in the "big data" industry sector.

Freedom vs Free vs Open

  • Making money with foss
    Because we are interested in making money, this post will took us all over the place. On the one hand we have the greedy businesses, and on the other side the diligent developer. Licenses were never discussed in hbo or university, which is interesting because these are the methods corporations use to make money. I think having discussed the overview and shown some concrete examples was a good exercise. I was not aware at all for example of the AGPLv3 practices which are interesting (without passing moral judgment). My blog seems to be really focused on money, but this is a reflection of what I'm worried about these days, having almost graduated.
  • Open-source software may save money, but what about monetization?
    While the open-source delivery model has emerged as a highly popular success, the problem remains that free downloadable software does not usually lead to revenue. But a growing number of cloud network entrepreneurs are becoming convinced that focusing their efforts on providing specific services for the enterprise computing marketplace is their path to the promised land.
  • Finnish firm offers €30,000 prize to kick start open-source wood design
    Finnish materials firm Metsä Wood has launched the Open Source Wood initiative to encourage architects and engineers to make more use of the material. The idea is to make the company’s own intellectual property freely available to designers, and as an additional incentive, to offer a €30,000 prize for “exceptional designs” that are undertaken as part of the initiative and use one of its product lines.
  • Free vs Open
    Here’s why. Corporations are not people, and so can’t “behave ethically” — doing so requires consciousness as a minimum. The people they employ can be expected to behave ethically, but a corporation will follow its programming to optimise the objectives stated in its bylaws. The people tending the machine can steer it towards different ways of achieving those objectives and can express their ethical selves through their choices, but they are not free to justify preferences purely on the basis of ethics. As a consequence, most advocacy of Open Source has focussed on helping those corporate employees demonstrate the value arising from it rather than the values motivating the people involved with it.
