Containers are very tricky to implement. Trying to isolate sets of resources from each other completely, so that they resemble a discrete system, and doing it in a secure way, has to be addressed on a feature-by-feature basis, with many caveats and uncertainties. more>>
We've mentioned Autokey as a great tool for text replacement in real time on Linux. Thankfully, there's an option for Windows users that actually is even more powerful than Autokey! AutoHotkey is a similarly named application that runs strictly under Windows. more>>
I've covered a lot of various pieces of software that are designed to help you do scientific calculations of one type or another, but I have neglected a whole class of computational tools that is rarely used anymore. Before there was the electronic computer, computations had to be made by hand, so they were error-prone. more>>
For years I avoided installing keyboard shortcut tools on my computers. I thought dog-gonnit, if something needed to be typed out, I'd type every letter myself. Recently I capitulated, however, and I must say, going back seems unlikely. If you've never tried a text-replacement app, I highly recommend doing so. more>>
They use our stuff. Why not our values too?
At this point in history, arguments for using Linux, FOSS (free and open-source software) and the Internet make themselves. Yet the virtues behind those things—freedom, openness, compatibility, interoperability, substitutability—still tend to be ignored by commercial builders of new stuff. more>>
It's time for another Readers' Choice issue of Linux Journal! The format last year was well received, so we've followed suit making your voices heard loud again. I couldn't help but add some commentary in a few places, but for the most part, we just reported results. Please enjoy this year's Readers' Choice Awards! more>>
I love the Readers' Choice issue. I jokingly say it's because all the work is done by the community, but honestly, it's because I love hearing the feedback from everyone. Year after year, I inevitably learn about a new technology or application, and I'm usually surprised by at least one of the voting results. more>>
One of my career iterations put me in charge of a Windows server that had Apache and PHP installed on it to serve as a Web server for the corporate intranet. Although I was happy to see Apache used as the Web server dæmon, the installation on the Windows server was the most confusing and horrifying mess I've ever seen. more>>
I've been hesitating for a couple months about whether to mention sshpass. Conceptually, it's a horrible, horrible program. It basically allows you to enter an SSH user name and password on the command line, so you can create a connection without any interaction. A far better way to accomplish that is with public/private keypairs. more>>
How to add a language to Lubuntu.
If you right click the little flag or two letter county code on the right side of the LXPanel, you will get a menu. Choose “Keyboard Layout Handler” settings. On the right side of the window that just came up, navigate to “Keep system layouts” under “Advanced setxkbmap Options” and uncheck it. The “Keyboard Layouts” section of the window will become editable after that. Choose “+ Add” and a list of keyboard layouts will become visible. Choose the one that you want. It will appear under your default layout. Before you close the window, you must re-check “Keep system layouts”.
You have to have the language pack installed for the language that you just added. You do that by going to Menu->Preferences->Language Support. Choose Install/Remove Languages. Select your language and then Apply Changes. You do have to reboot for the changes to take effect and the download and installation of some languages may take a while.
Alert readers will know that I'm working on a major revision to my popular Wicked Cool Shell Scripts book to come out later this year. Although most of the scripts in this now ten-year-old book still are current and valuable, a few definitely are obsolete or have been supplanted by new technology or utilities. No worries—that's why I'm doing the update. more>>
I'm writing this in November of 2014. Since UEFI and secure boot are still fairly new, it could very well be that what I'm writing now is more or less obsolete even a short while from now.
To my recollection both of the systems had Windows 8 (and not Windows 8.1)
The two systems on which I made this work was
Step By Step Instructions
I presume here that you have a system with Windows 8 already installed, your PC uses UEFI and secure boot. If any of this is not true, you might find easier solutions than what I'm doing here
Note that the uEFInd screen shows the grub as a boot option. You don't really need that one. To get rid of it, boot into Linux, and remove the folder /boot/efi/EFI/ubuntu.
That did the trick for me.
I spent lots of hours trying to understand all this. The most help for me was the refind web site maintained by by Roderick W. Smith. http://www.rodsbooks.com/refind/secureboot.html
Like most families these days, our family is extremely busy. We have four boys who have activities and appointments. My wife and I both have our own businesses as well as outside activities. For years, we've been using eGroupware to help coordinate our schedules and manage contacts. The eGroupware system has served us well for a long time. However, it is starting to show its age. more>>
For new Linux users, the command line is arguably the most intimidating thing. For crusty veterans like me, green text on a black background is as cozy as fuzzy slippers by a fireplace, but I still see CLI Companion as a pretty cool application. more>>
I really stink at video games. I write about gaming occasionally, but the truth of the matter is, I'm just not very good. If we play Quake, you'll frag me just about as often as I respawn. I don't have great reflexes, and my coordination is horrible. more>>
OpenGL is a well-known standard for generating 3-D as well as 2-D graphics that is extremely powerful and has many capabilities. OpenGL is defined and released by the OpenGL Architecture Review Board (ARB).
This article is a gentle introduction to OpenGL that will help you understand drawing using OpenGL. more>>
Hardware errors are tough to code for. In some cases, they're impossible to code for. A particular brand of hardware error is the Machine-Check Exception (MCE), which means a CPU has a problem. On Windows systems, it's one of the causes of the Blue Screen of Death. more>>
