Android Candy: Google Keep

LinuxJournal - Fri, 2014, Dec19 - 13:21

I love Evernote. I pay for a premium membership, and to be honest, I don't think I even use the premium features. I just love Evernote so much, I want to support the company. But in the spirit of fair comparison, I forced myself to try Google Keep. more>>

Handling the workloads of the Future

LinuxJournal - Thu, 2014, Dec18 - 11:26

The history of computing can be traced by the popular buzzwords of the day. In fact, at some point we should run a contest where everyone submits their 5 all-time favorite computer industry buzzwords. There have been dumb terminals, smart terminals, client server, thin client, peer-to-peer, virtualization, containers, cloud, paas, saas, iaas…the list, and the acronyms stretch to the horizon. more>>

Raspi-Sump

LinuxJournal - Tue, 2014, Dec16 - 13:35

In June 2013, we had the unfortunate luck of a basement flood, caused by a tripped electrical breaker connected to our sump pump. There are so many things that can go wrong with a sump pump. You always are on guard for power outages, blown breakers, sump pump failures, clogged pipes and all manner of issues that can arise, which ultimately can end with a flooded basement. more>>

diff -u: What's New in Kernel Development

LinuxJournal - Fri, 2014, Dec12 - 11:36

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>>

Non-Linux FOSS: Don't Type All Those Words!

LinuxJournal - Wed, 2014, Dec10 - 12:42

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>>

Computing without a Computer

LinuxJournal - Mon, 2014, Dec08 - 11:14

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>>

Autokey: Shorthand for Typists

LinuxJournal - Thu, 2014, Dec04 - 12:55

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>>

How Can We Get Business to Care about Freedom, Openness and Interoperability?

LinuxJournal - Wed, 2014, Dec03 - 15:13

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>>

Readers' Choice Awards 2014

LinuxJournal - Tue, 2014, Dec02 - 14:36

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>>

December 2014 Issue of Linux Journal: Readers' Choice

LinuxJournal - Mon, 2014, Dec01 - 11:32
The Best of the Best

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>>

Non-Linux FOSS: XAMP

LinuxJournal - Wed, 2014, Nov26 - 13:25

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>>

The Awesome Program You Never Should Use

LinuxJournal - Mon, 2014, Nov24 - 13:11

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>>

Adding a Second Language to Lubuntu

AZ Loco - Thu, 2014, Nov20 - 18:25

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.

Days Between Dates?

LinuxJournal - Thu, 2014, Nov20 - 11:58

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>>

UEFI, Secure Boot, Windows 8 and Ubuntu 14.04 - more learnings

AZ Loco - Wed, 2014, Nov19 - 17:16

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

  • A Gateway NV52L15U laptop
  • An HP Pavillion TS 15 Notebook. Windows 8, Insyde Bios V F.34

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

  1. Install Ubuntu 14.04
    I did this from a DVD. It should also work from a live USB, but if you have more esoteric ways of installing (like multisystem for example), secure boot will probably make that impossible.
    After the install I saw various behaviours. The ones I remember are these:
    • The pc boots into the GRUB menu, and selecting Ubuntu works fine.
    • Selecting Windows fails with a message that a file couldn't be loaded
    • I can get to the "Bios" boot selection prompt and select either Windows or Ubuntu and they both start fine
    • The very first boot into Windows after the install somehow "reverts" the startup behavior back to a direct Windows boot (Grub isn't displayed). But usually when you get into the "bios" boot selection menu, you can still get to the Ubuntu install.
  2. Boot into Ubuntu and type these commands
    wget http://www.codon.org.uk/~mjg59/shim-signed/shim-signed-0.2.tgz
    tar -xpzf shim-signed-0.2.tgz
    cd shim-signed/
    sudo mkdir /boot/efi/EFI/refind
    sudo cp * /boot/efi/EFI/refind/.
  3. In Ubuntu, visit the following site: http://www.rodsbooks.com/refind/secureboot.html and download the refind-bin-0.8.3.zip. It should end up in your Download folder
    unzip the file refind-bin-0.8.3.zip
  4. type these commands
    cd refind-bin-0.8.3/
    sudo ./install.sh --shim /boot/efi/EFI/refind/shim.efi
    sudo cp keys/refind.cer /boot/efi/EFI/refind/.
    sudo cp keys/canonical-uefi-ca.der /boot/efi/EFI/refind/.

    sudo reboot

  5. at that point you should boot into the rEFInd boot screen. When there, enroll the following keys (see http://www.rodsbooks.com/refind/secureboot.html, section on enroll key from disk for details)
    refind.cer
    canonical-uefi-ca.der
  6. go back to the rEFInd main screen, and boot into windows.
  7. In Windows get a command window with admin privileges and type these commands
    mountvol s: /s
    bcdedit /set {bootmgr} path \EFI\refind\shim.efi

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

A GUI for Your CLI?

LinuxJournal - Mon, 2014, Nov17 - 11:31

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>>
