Tuesday 26th of April 2016 01:50:58 PM
Without a doubt, Ubuntu 16.04 is said to be the biggest and most significant release of the distro in years. In my opinion, the reason for this release's perceived significance comes down to one thing – Ubuntu snap packages.

My Linux Desktop — Hither and Yawn

Tuesday 26th of April 2016 12:53:47 PM
One out of six people who are told by me that their computer will be running Linux have at least an idea of what Linux is. One out of 30 have used it, or do use it outside of the home, whether at school or work. Maybe three out of 100 clap with glee, fully jacked up that they won't have to blow away a Windows install and replace it with Linux.

How to change timezone on Linux

Tuesday 26th of April 2016 04:19:08 AM
If the default timezone of your Linux system is not correct, you need to correct it to get accurate local time. Note that configuring NTP is not a solution for an incorrect timezone as NTP itself does not handle timezones. NTP handles time data in UTC, and actual local time is calculated by adding the local time zone offset.

    The DragonBox Pyra is a portable computer that looks like a cross between a tiny laptop and a Nintendo DX game console… and it kind of works like a cross between those devices as well.

The DragonBox Pyra is a portable computer that looks like a cross between a tiny laptop and a Nintendo DX game console… and it kind of works like a cross between those devices as well. It’s got a 5 inch display, a QWERTY keyboard, the Debian Linux operating system that can handle desktop apps as well as games, and physical gaming buttons. It’s been under development for several years, and it’s expected to be available for purchase soon for about 500 Euros (plus VAT). But if you want to help fund the developers you can now place a pre-order for 330 Euros and up. Read more

  • How Linux Frustrated Me Into Loving It
    I have been very interested in Linux since my entry into the Wonderful World of Unix in 2006. I found Ubuntu and installed it on a crappy Dell desktop computer I was given when I was doing online schooling. The computer originally came with Windows, and one day while I was browsing, I decided to search for “alternative to Windows.” Linux popped up right away. I had never heard of Linux before, but after voraciously reading article after article, I decided Linux was the path for my future.
  • HP Chromebook 13 is a business-focused Chrome OS laptop with USB-C
    In the grand scheme of things, Chrome OS is hardly a major player from a desktop market share perspective -- for now. With that said, the Linux-based operating system has captured the hearts and minds of many consumers. It has matured quite a bit too, becoming a viable Windows alternative for home users. Actually, it is a great choice for some businesses too -- depending on needs, of course.
  • Summary: Linux Scheduler: A decade of wasted cores - Part 1 - What is NUMA ?
    Last month, a research paper with title 'The Linux Scheduler: a Decade of Wasted Cores' was trending on the front page of HN. As an individual who is interested in Systems, I thought it would be good idea to read this 16 page research paper. I spent a good amount of time learning about different topics which were involved in it. This is the first post in the series in which I will try to summarize the paper.

  • Bunsenlabs Rc2
  • April is almost gone
    The second one was the release of pre-release isos of Mageia 6 and OpenMandriva Lx 3. I must say that both distros are doing a great job; the systems performed so well that they did not seem beta versions to me. I did not like Plasma 5, though... I am sure the KDE team is doing a great work, but I truly do not see what the point of this tablet-ready interface is. After all, KDE missed the tablet train (the Vivaldi tablet never saw the light of the day) and tablets are already in decline...

    It took us almost another month to prepare this third preview of our upcoming stable release we call Daniella. The Xfce edition remains our flagship offering and has received the attention it deserves. Few can claim to offer such a polished, integrated and leading-edge Xfce experience. We ship Xfce 4.12 with this release of Manjaro. We mainly focused on polishing the user experience on the desktop and window manager, and on updating some components to take advantage of newly available technologies such as switching to a new theme called Maia, we already using for our KDE edition.

  • No Time to Panic as One Quarter Shows Minor Dip in Smartphone Sales - Total Smartphone Market Will Grow This Year (and here's why)
    We now have the Q1 numbers from Strategy Analytics and IDC, the two last remaining of the classic four big smartphone industry analyst houses we used on this blog to calculate the industry average of the total market size, back when the 'smartphone bloodbath' started six years ago. And both SA and IDC are in exceptional, near-perfect agreement on the exact size of the market, we get a total smartphone market for Q1 at 334.8 Million units. That is down 18% from the Christmas sales Quarter (normal that Q1 is down) but for the first time ever in this industry, the YEAR-ON-YEAR comparison of Q1, so the January-March quarter last year 2015 vs now, is down. This has not happened in the smartphone industry in any YoY period. And some are now talking about 'peak smartphone'. That number COULD be a signal that smartphone industry growth has stalled and now peaked and smartphone sales will either plateau flat, or decline into the next year(s).

  • 3D Printer Crowdfunding projects
    Like every Kickstarter project, there is a risk. But I think that Trinus appears to be a good project, we need to wait to the launch and review a real machine to know if it worth it. Also, the Youtube Channel Maker’s Muse, made a review of the project and the company Konama, creators of Trinus, sent him a the 3d printer and he currently makes the review of this printer that pledged more then 1 million dollars on KickStarter.
  • Refactoring the open-source photography community
    Generally speaking, most free-software communities tend to form around specific projects: a distribution, an application, a tightly linked suite of applications, and so on. Those are the functional units in which developers work, so it is a natural extension from there to focused mailing lists, web sites, IRC channels, and other forms of interaction with each other and users. But there are alternatives. At Libre Graphics Meeting 2016 in London, Pat David spoke about his recent experience bringing together a new online community centered around photographers who use open-source software. That community crosses over between several applications and libraries, and it has been successful enough that multiple photography-related projects have shut down their independent user forums and migrated to the new site, PIXLS.US.
