Xiaomi Said to Launch a Linux Notebook

Filed under
GNU
Linux

Xiaomi is quickly becoming a major player in the tech gadget space. It’s already a huge smartphone maker in China, though has started to spread its wings into other arenas as well. Next up may be a new laptop, at least according to some specs that were recently provided by GizmoChina. As you’ll note from the image above, this looks like a MacBook Air – but don’t let that fool you just yet.

GizmoChina says that the Xiaomi notebook, powered by Linux, may cost under $500, though the specs suggest it may cost a bit more than that. The site says Xiaomi’s notebook will pack an Intel Core i7 Haswell processor, a 15-inch 1920 x 1080-pixel display and a solid 16GB of RAM. There’s no news on what sort of storage this will pack, though if it’s as thin as the picture suggests, it may have a solid state hard drive as well.

One of many reasons to love Performance Co-Pilot, is the fact that it is a fully fledged framework to do performance analysis. It makes it extremely simple to extend and to build anything on top of it. In this post we shall explore how simple it is to analyze your performance data using iPython and pandas.

Systemd Development Skyrocketed This Year

Filed under
Linux

Rising above all of the systemd controversies and in-fighting this year, systemd developers remained committed and did a heck of a job at adding code to the project.

As some complementary development statistics for systemd focused on 2014 to yesterday's lead developers of systemd article, I ran GitStats this morning on the latest end-of-year systemd mainline Git repository. The numbers speak for themselves and systemd grew significantly this year.

Purism Librem 15

Reviews

While the Librem 15 doesn't necessarily match my personal tastes for laptop hardware due to the overall size and the mouse in particular, the mission of the company definitely does. Up until this point there were few options for laptops that ran purely Free Software, much less any that had modern hardware and a modern look and feel. I believe Purism genuinely wants to create a quality laptop that will appeal both to the Free Software community as well as privacy advocates and the Librem 15 is a nice start. In this era of pervasive surveillance, rootkits bundled with corporate software, threats of hardware backdoors by nation states, and the overall increasing sophistication of attacks, I think Purism is on to something here. As more people value transparency as a means toward security, a computer that can provide the source code for every driver, application, and firmware it uses becomes more valuable.

I installed Ubuntu on it as my default OS, though I can go back to Chrome OS any time I want. I don't see any point in doing it.

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...

Desktop Linux and Open Source in 2014: Looking Back

Filed under
GNU
Linux

Clichéd though they may be, year-in-review pieces about desktop Linux—by which I mean Linux distributions designed for end users working on desktops, PCs and, perhaps, large-form mobile devices—are a tradition here at The VAR Guy (and, before that, at our late, great sister-site, WorksWithU, a blog dedicated to Ubuntu Linux). But at the end of 2014, there's not much to say about desktop Linux other than that it's now so mature, and open source momentum so focused on other niches, that the Linux desktop has seen little major action over the past 12 months.

Windows Phone Replaced with Ubuntu 14.04 LTS on Lumia 1020

Filed under
Ubuntu

Windows phone (Lumia 1020) is probably the last place where you would expect to see Ubuntu, but a user has posted images with Ubuntu running on this device and they seem to be legit.

The first thing that users might think is that someone ported Ubuntu Touch for the Lumia 1020 device and that would not be an impossible task. It would be difficult but not impossible. It would also be a difficult to install a custom ROM, but that's also not impossible. The interesting thing is that the images show an Ubuntu system running and not the Touch version.

My Linux story: I grew up on PC Magazine not candy

In 1998, the movie Titanic was released, mobile phones were just a luxury, and pagers were still in use. This was also the year I got my first computer. I can remember the details as if it were yesterday: Pentium 133MHz and just 16MB of memory. Back in that time (while running nothing less than Windows 95), this was a good machine. I can still hear in my mind the old spinning hard drive noise when I powered that computer on, and see the Windows 95 flag. It never crossed my mind, though (especially as an 8-year-old kid), that I would dedicate every minute of my life to Linux and open source. Being just a kid, I always asked my mom to buy me every issue of PC Magazine instead of candies. I never skipped a single issue, and all of those dusty old magazines are still there in Costa Rica. It was in these magazines that I discovered the essential technology that changed my life. An issue in the year 2000 talked extensively about Linux and the advantages of free and open-source software. That issue also included a review of one of the most popular Linux distributions back then: Corel Linux. Unfortunately, the disc was not included. Without internet at home, I was out of luck, but that issue still lit a spark within me. Read more

  • How to Read SAS Files in Python with Pandas

    In this post, we are going to learn how to read SAS (.sas7dbat) files in Python. As previously described (in the read .sav files in Python post) Python is a general-purpose language that also can be used for doing data analysis and data visualization.

  • How to Convert Python String to Int and Back to String

    This tutorial describes various ways to convert Python string to int and from an integer to string. You may often need to perform such operations in day to day programming. Hence, you should know them to write better programs. Also, an integer can be represented in different bases, so we’ll explain that too in this post. And there happen to be scenarios where conversion fails. Hence, you should consider such cases as well and can find a full reference given here with examples.

  • Thousands of Scientific Papers May be Invalid Due to Misunderstanding Python

    It was recently discovered that several thousand scientific articles could be invalid in their conclusions because scientists did not understand that Python’s glob.glob() does not return sorted results. This is being reported on by Vice, Slashdot and there’s an interesting discussion going on over on Reddit as well.
