Vegan Gyro & Tzatziki Recipe.

Posted in Food, Guides, Life in General by Cameron Kopas | No Comments »

I want to preface this post by letting you know that my browser’s spellcheck wants to replace “tzatziki” with “Kazantzakis” as in the author of Zorba the Greek.

Since I have been experimenting with vegan(ism?) for awhile (okay fine, it was a dare), I have been really craving a few things; buffalo wings, and gyros. The worst thing is that people are always eating buffalo wings at the bars I go to, and people are always eating gyros at the Mediterranean places I eat. So I have the good fortune of being constantly exposed to what I really want to eat, but cannot.

 

Tzatziki Recipe

You’ll want to start the tzatziki first, because it needs to sit for at least an hour in the refrigerator.  This is adapted from a combination of a dozen or so tzatziki recipes that I found online.

  • 16 oz (2 cups)  soy yogurt (unflavored)
  • lemon juice (1 1/2 Tbsp) (or 1/2 lemon)
  • 3 tsp minced garlic
  • salt & pepper to taste (15 grinds salt, 6 grinds pepper)
  • Dill weed (1/4 cup fresh, or 4 tsp dried)
  • olive oil (2 tsp)

I’m not sure if the olive oil is strictly necessary, but I added it anyway. I have also heard a suggestion to replace salt with celery salt, which is much stronger, but would probably taste pretty good.

Mix these ingredients well, I used an immersion blender for this. After blending, add the cucumber and again mix well.

  • cucumber (~1 1/3 cup,  finely diced, deseeded)

Once again, I’m uncertain whether deseeding is really necessary, and I only deseeded half of  my cucumber. This came from one fairly long cucumber, but I assume two normal sized cucumbers would work just as well.

If you don’t know how to dice a cucumber, you cut it in half lengthwise (at this point you can de-seed with a spoon), then cut it into long thin strips, line all the strips up, and go to town without chopping off your fingertips.

Thats all! refrigerate at least one hour to let the flavors mix.

 

Gyro Meat

Now Gyro is typically a mixture of lamb, beef, and spices (you get three guesses to figure out how many of those are vegan!). So, I replaced the meat with yves Meatless ground ( veg/vegan/kosher:parve ground beef replacement containing wheat & soy), and combined some spice recipes for meat gyro. This stuff smells horrible when you open the package, but actually tastes pretty good.

  • 1 package Yves Meatless Ground (12oz approxeq 1lb “meat”)
  • 1 1/2 tsp Dried Oregano
  • 1 tsp Garlic Powder
  • 1 tsp Onion Powder
  • 1 tsp Salt
  • 3/4 tsp Pepper

Mix all that stuff together in a bowl, and prepare to get really frustrated. The yves has a weird consistency since it has soybeans in it, but gyro meat is mashed really finely. What you’ll want to do is put the mixture  on the counter, cover it with wax paper, and smash it for about ten minutes. I ended up taking a rolling pin and rolling the whole thing really flat, then banging on it with the pin to try to crush it.

After the consistency is better, but still nowhere near where it needs to be, mould the whole thing into a really thin, flat layer (or a few), and cook on the stove on medium heat for about 5 minutes per side.  I at first tried making it into a log, cooking, and slicing (as you would with regular gyro meat), but this does not stick together well enough, so cooking it in patties the size you want to eat works well and sticks it together.  (If anybody has an idea for something to ass that would stick it otherwise, please let me know. I would say 1 egg, but thats not vegan…)

 

Put one of the “meat” patties on a pita bread with diced tomatoes, red onion, lettuce, and scoop some tzatziki on it! I know I’ve already said this, but it was the best food I’ve had since the last time I ate buffalo wings.

Middle Mouse Scrolling in Ubuntu 10.04 Lucid Lynx

Posted in Guides, Linux, Ubuntu by aliencam | No Comments »

For this release, Ubuntu switched away from hal/udev  and went back to the old xorg configuration (I like this much better). There have been improvements and changes to the xorg.conf since we last used it (8.10 wow that’s been a long time!)  so now instead of putting everything in one giant /etc/X11/xorg.conf file and risking a single typo from breaking your x-server, we can put files in xorg.conf.d . This splits up configuration files so they can be more easily organised.

Here are the steps to get the middle-mouse scrolling again in Ubuntu 10.04, the Lucid Lynx. This should work for just about every thinkpad, and this same procedure will work in any Linux operating system using the xorg.conf.d method (if the /usr/lib/X11/xorg.conf.d/ folder doesn’t exist, then your distro is probably not using this method).

Begin by opening a terminal, and editing/creating the configuration file:
sudo gedit /usr/lib/X11/xorg.conf.d/20-thinkpad.conf

Now, paste in the following contents:
Section "InputClass"
Identifier "Trackpoint Wheel Emulation"
MatchProduct "TPPS/2 IBM TrackPoint|DualPoint Stick|Synaptics Inc. Composite TouchPad / TrackPoint|ThinkPad USB Keyboard with TrackPoint"
MatchDevicePath "/dev/input/event*"
Option "EmulateWheel" "true"
Option "EmulateWheelButton" "2"
Option "Emulate3Buttons" "false"
Option "XAxisMapping" "6 7"
Option "YAxisMapping" "4 5"
Option "EmulateWheelTimeout" "200"
EndSection

you’ll probably want to delete and re-type all of those quotation marks, I don’t trust wordpress’ “code” tags to keep those straight. Then you’re ready to save and close the file. A quick restart of X (reboot your computer, or ctrl-alt-backspace if you enabled that in System > Preferences > Keyboard > Layouts > Options > Key Sequence to Kill the X Server > check the box. )

The line “EmulateWheelTimeout” is not absolutely necessary, but it does help prevent things from being randomly pasted everywhere whenever you try to scroll (for some reason people think it is funny to automatically map middlemouse to “paste”).

Wacom CPL Config in Karmic

Posted in Guides, Linux, Ubuntu by aliencam | No Comments »

to stylus > tool buttons > then set “button 2” to “right” and “button 3” to middle.

The wacom control panel setup in Ubuntu 9.10 is, of course, different from what it was in 9.04, moving closer to what it was in 8.10…

anyway, wacomcpl is a very useful tool for changing settings and recalibrating your wacom tablet, and the “touch” is miscalibrated by default with a karmic install, so this is necessary to get much use of “touch”.

start by installing wacomcpl:
sudo apt-get install wacom-tool

now, create the wacom configuration file:

sudo gedit /etc/hal/fdi/policy/wacom.fdi

and paste in the following content:

<?xml version="1.0" encoding="UTF-8"?> <!-- -*- SGML -*- -->
<deviceinfo version="0.2">
<device>
<match key="input.x11_driver" contains="wacom">
<match key="input.x11_options.Type" contains="stylus">
<merge key="info.product" type="string">stylus</merge>
</match>
<match key="input.x11_options.Type" contains="eraser">
<merge key="info.product" type="string">eraser</merge>
</match>
<match key="input.x11_options.Type" contains="touch">
<merge key="info.product" type="string">touch</merge>
</match>
</match>
</device>
</deviceinfo>

save and close, reboot your computer, and run wacomcpl by hitting alt-f2 and entering “wacomcpl”. From here you can change settings or calibrate as you wish.

Now, I like the button on the side of the stylus to be right-click, so go to stylus > tool buttons > then set “button 2” to “right” and “button 3” to middle.

sorry if this isn’t as coherent, wrote this entry really quick as a response to a comment. let me know if anything needs clarification, or if it doesn’t work.

Ubuntu Setup Guide Part IX.Shortcut keys

Posted in Guides, Linux, Ubuntu by aliencam | No Comments »

This is a really short section, and should be put in the “customizing Gnome’s Look & Feel” area.

The Gnome “Keyboard Shortcuts” editor does not always work, for example, you cannot set any Super+___ shortcut keys using that, so unfortunately, we must once again use the Compiz Commands Plugin.

Open “compiz control settings manager” (if you don’t already have it installed do: sudo apt-get install compizconfig-settings-manager)

click the “Commands” plugin (it should be at the very top) and enable it if it is not already enabled.

Now in the “Commands” tab, enter whatever command you want to launch (pick any unused number, it does not matter which)

Now, switch to the “Key Bindings” tab. Here is where you will record what key combination you want to launch the command. Click the word “Disabled” then check the “Enabled” checkbox on the window that comes up. Once you click “Grab Key Combination,” the next key combination you press will be recorded.

The combinations that I have set both launch an open terminal window, but since I have two different terminal profiles (one with a transparent background, and another with green text on black background for high-contrast), I want one shortcut to launch each profile.

In the “Key Bindings” I have “XF86Launch1” (ThinkVantage button) as “Command 0” and “Super_L+Tab” (windows key+ tab) as “Command 2”.

In “Command” I have Command 0 set to:
gnome-terminal --window-with-profile=Terminal
(the word “Terminal” being the name of my high-contrast terminal profile)
and Command 1 is set to:
gnome-terminal --window-with-profile=Transparent
(“Transparent” is the name of my transparent profile)

That’s all, as soon as you close out of CompizConfig the settings should take place.


Setting the Windows (Super) Key to open the Main Menu:

If you want the Windows (or Super) key to open the main menu, you can set it up, but the problem with this is once the shortcut key is set, you can’t use any other shortcuts with the Super key (I use it for lots of things already, so when I realized this, I had to disable it).

For this one, you actually have to use the gnome “Keyboard Shortcuts” editor (correct me if I’m wrong please). So, first (and only!) step is to open that up (System> Preferences> (Input>) Keyboard Shortcuts)
Under the “Desktop” header, find “Show the Panel’s Main Menu” click on the “Alt+F1” on the right, then hit the Super key.

Unfortunately, this removes the alt-f1 shortcut that many people are used to… I don’t know how to have both set at the same time.

Mathematica 7.0+ in Linux >2.6.27

Posted in Guides, Life in General, Linux, Lists, Ubuntu by aliencam | 3 Comments »

There is a major usability problem in Mathematica 7.0.0 in any linux distros using a kernel newer than version 2.6.27.  This includes Jaunty, and it will be any other new distros.  The problem is on Mathematica’s end, but Wolfram has offered a fix for the issue.

If you are using Mathematica 7.0.1, then you do not need this fix. ASU only offers 7.0.0 to us though…

First, download the following files to your desktop:

http://download.wolfram.com/?key=GM5YM4

http://download.wolfram.com/?key=61JJHE

http://download.wolfram.com/?key=MK4ZR8

http://download.wolfram.com/?key=YHDAH4

Now, open a terminal and enter the following commands (a $ means a new command, don’t actually type that..)

$ cd ~/Desktop

$ sudo mv ./libML32i3.so /usr/local/Wolfram/Mathematica/7.0/SystemFiles/Libraries/Linux/

$ sudo mv ./libML32i3.so /usr/local/Wolfram/Mathematica/7.0/SystemFiles/Libraries/Linux-x86-64

$ sudo mv ./libML64i3.so /usr/local/Wolfram/Mathematica/7.0/SystemFiles/Libraries/Linux-x86-64

$ unzip ./JLink.zip

$ sudo mv /usr/local/Wolfram/Mathematica/7.0/SystemFiles/Links/JLink /usr/local/Wolfram/Mathematica/7.0/SystemFiles/Links/JLink-bak

$ sudo mv ./JLink /usr/local/Wolfram/Mathematica/7.0/SystemFiles/Links/

Thats it, now Mathematica runs nicely!

Installing Firefox 3.5 In Ubuntu (completely)

Posted in Guides, Linux, Ubuntu by aliencam | 3 Comments »

Firefox 3.5 came out a few days ago, and I always want to have the most updated version of everything. It won’t be in the Ubuntu repositories until 9.10 is released.

First step is from Lifehacker, it downloads and unpacks the file from the firefox website.

Open a terminal window and enter:
wget -O - http://releases.mozilla.org/pub/mozilla.org/firefox/releases/3.5/linux-i686/en-US/firefox-3.5.tar.bz2 | tar xj -C ~

Now, this shouldn’t overwrite firefox 3.0, but we need to move it to the mozilla folder, so use the following command:

mv ~/firefox/ ~/.mozilla/firefox3.5/

Now, make a symbolic link to firefox 3.5 in the equivalent of a “programs” folder (/usr/bin in Ubuntu):
sudo ln -s ~/.mozilla/firefox3.5/firefox /usr/bin/firefox-3.5

NOTE: you may only have one version of firefox open at one time. To open Firefox 3.5, you must completely close all other versions of firefox.

Now to set the firefox icon to the new firefox program (when opening in gnome-do and if you make a panel shortcut) open your home folder, hit ctrl-h (to show hidden files), go to .mozilla/firefox-3.5, right-click on the “firefox” in there, go to “properties” then left-click on the icon (top left corner). Now go to Pixmaps on the left (or /usr/share/pixmaps) and select firefox-3.0.png.

Now, there are a few ways to set up a shortcut to open firefox. One of the easiest is to add it to the program menu. Open the menu and go to System > Preferences > (Display >) Main Menu. Now open the “Internet” section (in the left column), and create a “New Item” with name: Firefox 3.5, command: firefox-3.5, and once again, the icon should be /usr/share/pixmaps/firefox-3.0.png.

Another method is, if you use gnome-do, just open it (alt-space) and when you start typing “firefox,” hit the down arrow and select “Firefox 3.5” (I think this only shows up after a restart, or if you add the firefox 3.5 menu item above).

Firefox 3.5 has some interesting quirks though. Flash will not work for it unless you copy your plugins into it.

In Ubuntu though, you need to copy plugins for multiple locations. Use this set of commands to copy all the plugins:
cp /usr/lib/flashplugin-installer/libflashplayer.so ~/.mozilla/firefox3.5/plugins/ && cp /usr/lib/mozilla/plugins/* ~/.mozilla/firefox3.5/plugins/

you also need to disable the strange middle-mouse behavior in 3.5. go to about:config in firefox, click the “I’ll be careful I promise!”, and go to: middlemouse.contentLoadURL and if it is true, double-click on it to make it false.

the only thing I have yet to figure out is why all the fonts in firefox 3.5 seem to be blurry, while 3.0 was perfect… To me it is like the difference between subpixel smoothing and high contrast font rendering modes… see the screenshots below. (left is non-blurry firefox 3.0, right is blurry firefox 3.5)
ScreenshotScreenshot-1

UPDATE: There were a few forum topics about this issue, but nobody had a definitive solution. Many possible solutions, but many of them were kind of strange, and many did not work.

Here is what worked for me:

open a terminal, and this first step is a backup just in case the next step messes up your system’s fonts.

sudo cp /etc/fonts/conf.d/10-hinting-slight.conf /home/$USERNAME/Desktop/
sudo cp /etc/fonts/conf.d/10-no-sub-pixel.conf /home/$USERNAME/Desktop/

Now, the files were just copied to your desktop, here are the next two commands:
sudo ln -s /etc/fonts/conf.available/10-hinting-medium.conf /etc/fonts/conf.d/.
sudo ln -s /etc/fonts/conf.available/10-sub-pixel-rgb.conf /etc/fonts/conf.d/.

And finally, you need to reset fontconfig:
sudo dpkg-reconfigure fontconfig

Once this finishes, restart Firefox to see the new fixed font rendering engine! You should also restart your computer to ensure that removing those files did not do any harm. If you restart and you can still see text, then you are okay to:
sudo rm /home/$USERNAME/Desktop/10-hinting-slight.conf /home/$USERNAME/Desktop/10-no-sub-pixel.conf

Now you are finished!

Ubuntu Setup Guide Part VII: Pidgin

Posted in Guides, Linux, Lists, Ubuntu by aliencam | 5 Comments »

Customizing Pidgin Settings:
if you use any instant messaging program, you will want to setup Pidgin to work with all of your accounts. It may be ugly and awkward to use at first, but once you change it’s settings it is actually very stable, quick, and it works perfectly for me.

When you first open Pidgin, you will need to add an account, just click “add”, then select the type of account it is, and enter your information. You can add as many accounts of any type as you like to pidgin, and it combines them all very well. Make sure you check the “remember password” option, or you will have to log into each account every time you start pidgin.

Once you finish that, go to Tools > Plugins, and enable the following plugins:

  • Buddy Notes
  • Buddy State Notification
  • Contact Availability Prediction
  • Log Reader
  • Psychic Mode
  • Timestamp
  • Pidgin-Encryption

You’ll also want to download the pidgin-facebookchat plugin from http://code.google.com/p/pidgin-facebookchat/  in order to be able to chat on facebook without actually logging onto the website.  (I don’t think I have actually typed in facebook.com in months, I chat through pidgin, reply to messaes via email or SMS, and update my status vis Twitter.)  To download the latest version, go to the website, and download the .deb file in the top right corner of the page. Then just install it by double-clicking on it.   Then restart Pidgin, and go back into the account manager (ctrl-a) and add the facebook account.

Now, go to Tools > Preferences and uncheck “show IMs and chats in tabbed windows”.  Then, select “None” in Smiley Themes.  Under “Logging” change “Log Format” to HTML.

If you have previous log files, you can copy those from your backup into /home/USERNAME/.purple/logs  andthey will work even if previous logs are from deadAIM, Trillian, and other AIM clients.

Finally, there are way too many libnotify alerts with all my accounts enabled, so go into File > Plugins,  scroll down to libnotify, and uncheck “Buddy Signs on”.

Ubuntu Setup Guide Part VI. Customizing Gnome's Look & Feel

Posted in Guides, Linux, Lists, Ubuntu by aliencam | 3 Comments »

I don’t really like the way Ubuntu’s default Gnome setup looks. Primarily because I have my tablet, which has a small 12.1 inch screen. I also like to change the theme. Since I have such a small screen, I will do almost anything to increase how much information I can see at the same time (short of getting a laptop with a bigger screen, or an external monitor, of course.) So, many of these tips are inspired or taken from Ubuntu Netbook Remix.

To illustrate the changes I make, here are before and after screenshots of my computer’s look.

Original Final

First step is to install window picker applet: a window picker in your title bar that also has a window close button, and maximus: a program that removes the title bar (the bar with the maximize, minimize, and close buttons) or “un-decorates” maximized windows.

sudo apt-get install window-picker-applet maximus

now the default behavior of maximus is to force all window to be maximized, to change this, add the argument “-m” when running it. It automatically runs on boot, so to change this, go to System > Preferences > Startup Applications, find “Maximus Window Management” in the list, choose it, and click “edit”. Then, change the command to “maximus -m”.

Now, you need to add the window-picker-applet to your Gnome Panel in order to be able to close the open window easily. Right-click on the top middle part of the top Gnome Panel (the bar at the top of the screen), go to “Add To Panel” and add “Window Picker”.

Removing Useless Panel Things:
Remove the following panel applets by right-clicking on them and selecting “Remove From Panel”:

  • User Switcher Applet (top right corner) (also remove the seperator [line] to the left of it).
  • Menu Bar (top left corner, its the equivelent of the “start menu”
  • The three shortcuts next to the menu bar (Firefox, Mail, and Help)  (if you are using Gnome-do, you don’t need them)

Now, remove the ENTIRE BOTTOM PANEL by right-clicking in a blank area, and selecting “Delete this panel”

Add the following panel applets to the top panel in this order (left to right) If you don’t know what the applets you already have on the panel are called, then just remove all the applets and start from a blank top panel.

  1. Main Menu
  2. Drawer (optional: use this if you want some program shortcuts in the menu bar still.)
  3. Window Picker
  4. CPU Frequency Scaling Monitor (go to Preferences and set this to be the icon to take up less space)
  5. Notification Area
  6. Indicator Applet
  7. Volume Control
  8. Workplace Switcher
  9. Clock
  10. Trash
  11. Shut Down

You should configure the clock by adding your location (right-click > preferences > location) and removing the date so it is smaller.  This way you get the date on mouseover, and the weather to the left of the clock at all times.

You also may want to shrink or grow the panel size by a few pixels, the icons in window-picker are cut off a bit at the default 24 pixels, if that  bothers you increase it to 26,  but you can actually decrease it all the way to 23 px and it still be usable.

Now, to change Ubuntu to a darker colour theme (I don’t like my screen to burn my eyes), right-click on the desktop (get to the desktop by hitting crl-alt-d now), go to properties, and “change Desktop Bakcground”, then you can go to the “Themes” tab and select Dust.  I also go to the “Fonts” tab, and change the font rendering to “Best Contrast” instead of “subpixel smoothing”.

Removing Menu Items

When I installed all those programs, I also installed all of the suggested programs.  These ensure that more features of the programs will work, and more smoothly, but it also clutters up my programs menu with a bunch of stuff that I will never use, things like dolphin and konsole are unnecessary when you are using Gnome.

Unfortunately, editing the Gnome menu is not as easy as it is in Windows (this has to be one of the only things I think windows does wayy better)  You must use the slow and clunky and buggy Menu Editor program. (significantly improved from the last version, but still not great)

Click your new Menu Button (top left corner) go to System > Preferences > Main Menu.

Now you can go through, reorganize, and remove the icons you don’t want.

Here is a list of changes I made in no particular order:

  • move cellwriter from Universal Access to Acessories (drag to copy, then uncheck in the original location)
  • In Accessories, uncheck kwrite
  • In graphics, uncheck Hugin Batch Stitcher (its a terminal app used by the panorama creator…)
  • Move Bluefish Editor from Programming to Office (drag to copy, then uncheck in the original location)
  • Move Fusion-Icon from System Tools to Accessories (drag to copy, then uncheck in the original location)
  • In System Tools, uncheck Dolphin and Konsole
  • Uncheck everything in “Other” (this is all repeated in the Preferences menu)
  • In Preferences, Create the following new menus: “Display”, and “Input”.
  • Move “Appearance”, “Compiz Config Settings Manager”, “Main Menu”, “QT4 Settings”, “Screensaver”, and “Windows” from Preferences  into Preferences > Display  (you have to drag it to the display folder in the left sidebar, then uncheck the originals)
  • Move “Ketboard”, “Keyboard Shortcuts”, “Mouse”,  “On Board” and “On Board Settings (check these), and “SCIM Input Method Setup” from Preferences in to Preferences > Input. (you have to drag it to the display folder in the left sidebar, then uncheck the originals)

Ubuntu Setup Guide Part V. Installing Software

Posted in Guides, Linux, Lists, Ubuntu by aliencam | 2 Comments »

I install lots of software that I use nearly every day. Here is a list of what I am installing from the start:

(*) gnome-do
(*) crossover office (PAID SOFTWARE) [Microsoft Office 2008, Vector Magic]
(*) crossover games (PAID SOFTWARE)
gcolor2
gscan2pdf
hugin
inkscape
(*) dropbox
ktorrent
nicotine-plus
(*) opera
abiword
bluefish
(*) banshee
dvd::rip
(*) gpodder (needs python-gpod to work with iPods)
pulse audio volume control (pavu-control)
VLC
compiz fusion icon
(*) Mathematica 7
compiz control settings manager (ccsm)
powertop
gparted
ntfsprogs
hfsprogs
kerneloops
gthumb
subversion
bootchart
wacomtools
xflux (see my guide on installing this)
citrix (see my guide on installing this)

Those programs prefixed with (*) should NOT be installed from the Ubuntu repositories. Either they are not in the repos, or I don’t like the version in the repos.

In order to do this, some custom repositories (Launchpad PPAs) must be added. See the following section for how to install software from Launchpad PPAs.

If you want to install most of these at once, you can use the following command:
$ sudo apt-get install gcolor2 gscan2pdf hugin inkscape ktorrent nicotine bluefish dvdrip pavucontrol vlc fusion-icon compizconfig-settings-manager powertop gparted kerneloops gthumb subversion bootchart ntfsprogs hfsprogs wacom-tools xournal cellwriter

Installing Software from a Launchpad PPA.

In order to do this, open System > Administration > Software Sources > Third Party Software and “Add” the following lines:

deb http://ppa.launchpad.net/banshee-team/ppa/ubuntu jaunty main
deb-src http://ppa.launchpad.net/banshee-team/ppa/ubuntu jaunty main

Once you do this, click close, but not refresh (if you do refresh you will get an error, just ignore that until you complete the next step.)

Now for the tricky part of adding custom PPAs — adding the public keys. What you will need to do from the launchpad PPA page is follow these instructions:

On each Launchpad PPA Page will be a line of text similar to the following:
screenshot

“This repository is signed with 1024R/6E80C6B7 OpenPGP key. Follow these instructions for installing packages from this PPA. ”

To install the key, click the link that the numbers are linked, and then again click the “Key ID” link on the next page (another set of numbers). Now you will be at the public key page. From here, copy-paste everything from
“—–BEGIN PGP PUBLIC KEY BLOCK—–” to “—–END PGP PUBLIC KEY BLOCK—–”
into a new text document (make it on your desktop, it doesn’t matter where really). Then save this document with any name, close the text editor, then open back up System > Administration > Software Sources, go to the “Authentication” tab, click “import key file” then select the file you created. Once you do this you are okay to delete the file.

Now you are ready to install the program from synaptic, or apt-get.

Easy Batch Image Conversion in Ubuntu

Posted in Guides, Linux, Ubuntu by aliencam | No Comments »

I just had a stack of 25 .bmp files that I needed to convert to .jpg for a review I’m writing over at maximumcpu.net (Big C Digital Microscopes) so here is an easy way to to that. You can probably do this between just about any two standard image formats. Unfortunately, this does not preserve filenames when bulk converting.

In a terminal:

sudo apt-get install imagemagick

cd ./Desktop/pictures (change this to whatever you need to)

convert ./*.bmp .jpg

there, simple. it pumps out all the files with the filenames just being numbers in order.
