I have released a new version of the Semi-Automatic OS v. 5, a free virtual machine based on Debian Linux, for the land cover classification of remote sensing images. It includes the Semi-Automatic Classification Plugin (SCP) and QGIS, already configured along with all the required dependencies (OGR, GDAL, Numpy, SciPy, and Matplotlib).

Since my trusty old Mediacenter + NAS is starting to breathe its last breaths, I've been looking for alternatives for my storage and multimedia needs. I thought about taking another approach to the subject this time and use a tiny board instead of a full tower. My demands were the following:
Only these will limit your available choices considerably already. Luckily I found a device that seemed to suit these needs: the Beelink Z83 which is a small atom box. It is powered by the Atom X5-Z8300 with its integrated graphics and features Gigabit Ethernet, a USB 3 port, 2 USB 2 ports, an HDMI port, an headset jack, Bluetooth, an SD card slot and WLAN for both 2.4 and 5.8 GHz. The device comes with 32GB of eMMC storage and has 2 GB of DDR 3 that is clocked at 1600 MHz IIRC (I don't have the device here since I'm travelling). You can find the device on Gearbest. The manufacturer's website doesn't list it under products, but they discuss it in their forums so it's not a knockoff. It's basically the same as this one, but with less storage. It came preinstalled with Windows 10 but gives you no trouble installing something else. You can choose the UEFI entry freely once you have attached a keyboard.
I installed Arch Linux on it. By default, the following will not work:
I have not tested the following yet:
So after a bit of research it turns out that Intel not only has their HD Audio implementation, but also another method that is currently out of the main kernel tree and initially written for Android as the hardware platform is targeted at tablet devices. Long story short there is a Github repository by an Intel employee with the 4.7 kernel and the sound enabled, you can check it out and apply the 4.7.x patches against it. Just be aware that the intel code will not compile with current GCC without modifications. If anyone is interested, I'll upload the PKGBUILD to the AUR. With the patch applied, you have sound over HDMI.
Both the USB 3 and the Gigabit Ethernet port do as expected. I don't have a recent HDD to test, the one I hooked up to it is about 8 years old already and makes dangerous noises. No problem since it's just for testing but it already puts about 75 MB/s on it so the port is not USB 2 in disguise or something.
I run kodi on the device and it works like a charm. It decodes both H264 and H265 in hardware and up to 4k. I only have a 1080p screen to test though and 4k is only 30 fps as far as I know. Unfortunately I think it doesn't have CEC (I only know of the Raspberry Pi as a device that does) so if you want to use that you need to get yourself one of those splitters. I Under load, the device gets quite warm since it's only cooled passively.
Despite the stuff not working (WLAN, SD card reader, the headset jack), I think it is quite good bang for your buck. For about $90, you get Gigabit Ethernet, USB 3.0, open drivers, a case, a mount, two HDMI cables with different lengths and the power supply (12V 2A). Some multimedia distributions (like librelec) ship with the kernel patches already applied. The WLAN woud be the icing on the cake for me as I'd like to use it as an AP but what can you do.submitted by /u/DamnThatsLaser
Here we are, at the end of this article. It serve no purpose really. But it shows that CentOS can be as relevant, stylish, slick, and modern as any other distro. Which is even more amazing when you take into account its age, its relative conservatism, the fact it will be supported for another bunch of years, and that it still competes well and true with all the latest and greatest home distros, with infinitely more stability.
Just remember this is a server distribution, and its purpose in life is to run code and make money and whatnot. It's not there to entertain your laptop, and yet it can do that pretty well. Everything you need Linux wise is there. Including some fireworks. Maybe this article serves no higher goal, but perhaps you are ever so slightly delighted and entertained. If you have any suggestions on how CentOS can be made even more elegant, please drop me a nice and friendly line. Meanwhile, I'm off to do some more CentOS testing, maybe even on the G50 box. Stay tuned.
Oh, one more thing. We have only just begun. If you think this is the sum of all pretty, then I have a few surprises up my sleeve - wizard's sleeve, Borat style. You will need to exercise patience for a few more days or weeks, and then I shall reveal unto you. But it will be good. I guarantee that. Now, for real, stay tuned.
There you go. This is the ordeal that I had to undergo to finally have a fully working Xfce desktop in CentOS 7.2, loaded with all the right goodies, like software, codecs, and support for my gadgets, plus the necessary aesthetics. Most people take this kind of work for granted, and expect results from distro developers and distributions, which is perfectly legitimate. So if you find this unnecessary, I totally agree with you.
Except, CentOS is a server distro, and it brings its special perks to the desktop, for the price of some extra work on your behalf. Moreover, you won't need to be repeating yourself, and you won't be plagued with regressions, so your effort won't be wasted. In the end, it comes down to ROI. For me, the technical bits culminate in some expected look & feel tweakology, a new menu, sound and audio changes, and a few other bits and pieces. Much simpler and shorter after you've done this once and know what to expect. Perhaps then, this little exercise won't be an ordeal for you, but a pleasurable little escapade and a long-term investment. I hope you enjoy it.
elementary OS 0.4 "Loki" has released at 9 September 2016. I tried elementary OS Loki for 6 days and now it's time for the review. I wrote this review for beginners and first timers in GNU/Linux, especially in elementary OS. I cover shortly 18 aspects such as shortcut keys, memory usage, audio/video support, desktop experiences, and also elementary OS Loki default software applications. As overall (mentioned below), it's really exciting and comfortable experience for me to review and use elementary OS now, in Loki release. I hope this review is really helpful to you.
KDE is undoubtedly free software, both in word and in spirit. Recently I saw many projects tend to FSF for hosting and certification and of course for ideological reasons.
Why this doesn't happen with KDE? They seem as a solid entity, strong by itself, is this the case? What are relationships of FSF with such big projects as KDE then?
P.S. I know there is no tension between these projects, I see FSF resolution that KDE is finally Free Software back in 200x and KDE site has FSF link in "About" page. Just curious :)submitted by /u/Antic1tizen
So I recently (couple days ago) bought a second-hand notebook, that came with Windows 7 Starter. It is agonisingly slow. After doing some research I decided that my best bet if I wanted to keep using it was to install Linux - specifically a "fast" type like lubuntu. However I have never installed Linux before, nor have I done more than reboot my old Macbook from disk. So I have no idea how to really go about this other than what Google has told me.
I see that apparently I should 1: get hold of a 2 GB USB stick, and format it to FAT16 (my notebook is from 2011). 2: install lubuntu onto said stick, apparently in a way other than copying files over - using UNetbootin? 3: reboot notebook using stick instead of Windows OS.
But then I also want to wipe the hard drive completely because apparently that helps speed things up and also I want nothing to do with Windows 7 or any of the manufacturer programs, so how do I do all this stuff properly?
If anyone could advise me I'd be very grateful :)

Since Chromebooks first hit the scene, Samsung has had options available. The Samsung Series 3 Chromebook was one of the most popular Chromebooks ever, but in the time since Samsung’s Chromebooks have faded into the background a bit with the focus shifted to options from HP, ASUS, Acer, and many others. With Android apps on the horizon, it seems that Samsung is finally pushing its Chromebook lineup yet again, but it might be doing that in the wrong way…
