Three Reasons Why You Should Upgrade from Ubuntu 12.04 LTS to Ubuntu 14.04 LTS

Filed under
Ubuntu

One of the best reasons to upgrade to Ubuntu 14.04 LTS is by far the new Linux kernel stack that comes with the new version. Ubuntu 14.04 includes the 3.13.0-24.46 Ubuntu Linux kernel which is based on the v3.13.9 upstream stable Linux kernel, which is one of the newest ones made available.

Radeon: Mesa 10.1 vs. Mesa Git On Ubuntu 14.04

Graphics/Benchmarks
Ubuntu

Most of the performance changes to be found between Mesa 10.1 stable and the current Mesa Git code just past the 10.2 branching was around the HD 7850 graphics card that uses the RadeonSI Gallium3D driver while the other three graphics cards used the R600g driver. With R600g and our assortment of Linux gaming and OpenGL benchmark tests run, we didn't see any better performance in the code beyond where it's at with Mesa 10.1.

First Linux Kernel Update Arrives for Ubuntu 14.04 LTS, Upgrade Now

Filed under
Linux
Ubuntu

Every now and then, Canonical issues Linux kernel updates for all the operating systems that are being supported at that time. In this case, there are five distributions that have received this new upgrade, but it's interesting to note that not all the OSes share the same kernel, which means that it was a problem common to all, regardless of the version.

Testing a new laptop with openSuSE, Fedora, Linux Mint and more

Ubuntu

In order to install Linux from a bootable USB stick I need to be able to get to the Boot Selection menu, but on Acer systems with UEFI firmware, this is a bit tricky. The Boot Menu key (F12) is disabled by default, so I first have to boot to the BIOS Setup Utility, by pressing F2 during the power on or reboot cycle. Then in the Main setup screen there is an option to enable "F12 Boot Menu".

That's one trick down, but there's another one which might be required. Depending on what version of Linux you want to install, and perhaps how you feel about Secure Boot, you might want/need to disable that. In the BIOS Setup Utility, on the Boot menu there is an option to disable Secure Boot - but I can't get to it: moving the cursor down just skips over it!

I can change boot mode from UEFI to 'Legacy BIOS', but that isn't what I want to do. I learned (the hard way) with my previous Acer Aspire One, that I have to go to the Security menu and set a "Supervisor Password" before it will let me disable Secure Boot mode. I'm sure this makes sense to someone, but whoever that is, it isn't me.

In this case I am going to start by installing Linux with Secure Boot still enabled, so I don't really have to do this, but I went ahead and set a supervisor password anyway, because I will eventually want to turn off Secure Boot anyway.

The Ubuntu Unity Launcher gets a facelift with Unity Drawers

Filed under
Ubuntu

For the longest time, Ubuntu Unity users have wanted a bit more leverage from the Unity Launcher. As it stands, it's a means to launch applications and get to the Unity Dash. But with the creation of a new tool, Drawers, you can easily organize related items (files, applications, websites, folders, etc.) using "mini dashes" and "quick lists" -- similar to the Stacks feature in OS X. Drawers allows you to organize files together onto the Launcher and even create a Dash-like app menu for quick access to your applications.

Opera Data Breach, Security of Personal Data

  • Opera User? Your Stored Passwords May Have Been Stolen
    Barely a week passes without another well-known web company suffering a data breach or hack of some kind. This week it is Opera’s turn. Opera Software, the company behind the web-browser and recently sold to a Chinese consortium for $600 million, reported a ‘server breach incident’ on its blog this weekend.
  • When it comes to protecting personal data, security gurus make their own rules
    Marcin Kleczynski, CEO of a company devoted to protecting people from hackers, has safeguarded his Twitter account with a 14-character password and by turning on two-factor authentication, an extra precaution in case that password is cracked. But Cooper Quintin, a security researcher and chief technologist at the Electronic Frontier Foundation, doesn’t bother running an anti-virus program on his computer. And Bruce Schneier? The prominent cryptography expert and chief technology officer of IBM-owned security company Resilient Systems, won’t even risk talking about what he does to secure his devices and data.

  • On speaking at community conferences
    Many people reading this have already suffered me talking to them about Prometheus. In personal conversation, or in the talks I gave at DebConf15 in Heidelberg, the Debian SunCamp in Lloret de Mar, BRMlab in Prague, and even at a talk on a different topic at the RABS in Cluj-Napoca.
  • TPM Microconference Accepted into LPC 2016
    Although trusted platform modules (TPMs) have been the subject of some controversy over the years, it is quite likely that they have important roles to play in preventing firmware-based attacks, protecting user keys, and so on. However, some work is required to enable TPMs to successfully play these roles, including getting TPM support into bootloaders, securely distributing known-good hashes, and providing robust and repeatable handling of upgrades. In short, given the ever-more-hostile environments that our systems must operate in, it seems quite likely that much help will be needed, including from TPMs. For more details, see the TPM Microconference wiki page.
  • More translations added to the SFD countdown
    Software Freedom Day is celebrated all around the world and as usual our community helps us to provide marketing materials in their specific languages. While the wiki is rather simple to translate, the Countdown remains a bit more complicated and time consuming to localize. One needs to edit the SVG file and generate roughly a 100 pictures, then upload them to the wiki. Still this doesn’t scare the SFD teams around the world and we are happy to announce three more languages are ready to be used: French, Chinese and German!
