Hollywood movies often have a tech geek entering commands and doing amazing things. While it may not be that easy to hack into public transport systems or or control the world like Eagle Eye, the command line is certainly a geeks playground.
Want to show off your command line prowess to your geeky friends but don’t know any cool tricks? Well you are in luck. The following websites will give you plenty of tricks and tips to satiate your hunger:
“Fu” is defined as possessing superior skills related to an art. Aptly named “Shell fu” houses user-submitted command line goodies, tips and tricks. You can vote entries up if you like them and vote them down if you find they are harmful or do not work as advertised.
If you have some tricks of your own you can even submit them and they will be added to the site after the moderators have a look at them.
Shell fu and Command-line fu are almost identical in concept. Command-line fu allows users to share their CLI wisdom with others and also vote up and down on submitted snippets.
Both shell-fu and command-line fu allow you to follow snippets through RSS and Twitter although I did find command-line fu offers a bit of extra control on RSS feeds.
Snipt is the “long term memory for coders”. Snipt is a collection of frequently used commands and code snippets. You can share these snippets with your co-workers or make them public. Public snippets are viewable to everyone and for our specific case, we are interested in the bash section. However feel free to browse other sections as well.
While all the other resources mentioned utilize the power of the crowds to build up content, this one is different. It is Peteris Krumins blog about programming, software and hacking.
What’s so special about it? The famous sed, awk one liners, vim tips, plugins and cheat sheets that Peteris has fabricated over time. The occasional musical geek friday is fun as well.
While it may not be updated as often as the others, but more often than not the content is worth the wait.
Pick up the basics
While the places mentioned above have plenty of content to keep you busy learning, they are not the best places to start your journey. If you want to start with basics have a look at Introduction to the Linux Command Line published on MakeUseOf earlier. You may also find command line basics here and here. For advanced topics you can read the Advanced Shell Scripting Guide.
That’s plenty of information to keep you involved and build up your Linux-fu! Do you know of any good sites to learn Linux commands? Or have you referred to a Linux command line tutorial that you really like? Share with the world in the comments!
Fudzilla is reporting that Intel will release Arrandale-based processors on January 3rd, 2010. Three in fact, branded as “Core i5″ and “Core i7,” ranging in speed from 2.4GHz to 2.66GHz.
There are two Core i5 models. One features 3MB of cache, a 2.4GHz frequency, two cores and four threads plus Turbo Mode, while the other features two cores, four threads, Turbo Mode, 3MB of L2 cache and a 2.53GHz frequency. Fudzilla prices them at $225US and $257, respectively.
Finally, the 2.66GHz Core i7 model features 4MB of cache and Turbo Mode and can run faster. Fudzilla expects them to sell for $332. You’ll remember that desktop Macs received Nehalem architecture processors earlier this year, which these Arrandale processors are based on. If built into Apple’s MacBook Pros, they’d represent a significant performance boost over the Core 2 Duo processors currently in use.

It seems like the hackers are at it again, and have rooted the Verizon Motorola Droid. For those who dont know this means soon you should be able to add custom features such as themes, Multitouch browsing, tethering, blue tooth files transfers ect! The possibilities are endless. We all know Verizon likes to lock down their phones, and the Motorola Droid is no exception. Any day now new hacks should start rolling out. Keep checking back for the newest hacks for the Motorola Droid, as they are released.
Heres the info from “Zinx Verituse” over at AllDroid.
Droid rooted
I’ve rooted the Droid;
md5sum of initial exploit zip: 94a0c30ea9104c2776d042e760bfd716
The exploit provides a /system/bin/su from AOSP (that is, you can only use it from adb shell).
Other payloads can be arranged, but I’m too lazy to make them myself.
Provide a decent payload and I will turn it in to an update.zip that the Droid will apply.
Restrictions: The payload zip must be <63k
I can add files already in the official update to it (update-binary).
UPDATE: 2009-12-09
New exploit zip, including Superuser from CyanogenMod
1) get signed -voles-ESD56-from-ESD20.84263456.zip (md5sum 3af35446905040a3123ec09195299596)
2) get droid-superuser.zip (this file, md5sum e517995a7d1fe233c61df17c7f7c2a63)
3) append this file to the end of signed-voles-ESD56-from-ESD20.84263456.zip
* Windows: copy /b signed-voles-ESD56-from-ESD20.84263456.zip+droid-superuser.zip update.zip
* Linux: cat signed-voles-ESD56-from-ESD20.84263456.zip droid-superuser.zip > update.zip
The md5sum of update.zip will be cf653352967253e99d967498ffd9ce69
4) Copy the update.zip to the sdcard on the phone
5) Boot the phone to recovery mode (hold X and power the phone on)
* You’ll get a triangle + exclamation point if done right
6) Apply the update by pressing Volume Up + Camera
There will probably be mirrors for the pre-concatenated version of droid-superuser.zip, so check this thread.
DETAILS:
Eclair has a new signature checking mechanism, which has a hole allowing unsigned updates up to a certain size.
bootable/recovery/verifier.c notes that a zip file could be hidden in the signature, and has measures to prevent this, but due to a copy/paste mishap, does not check for a hidden zip properly.
This was brought to my attention by embeem, a week or two ago. I do not know who mentioned the problem to him.
Patch that closes the hole:
After nearly five years of loyal service, Mininova disabled access to over a million torrent files when it partly shut down its website. Starting today, only approved publishers are able to upload files to the site, but luckily there are plenty of alternatives and potential replacements BitTorrent users can flock to.
Mininova, founded in January 2005, grew out to become one of the most successful torrent sites with millions of daily users.
The site has grown steadily over the years and continues to do so, despite a setback in court this summer. In fact, today the 10 billionth torrent file was downloaded from Mininova, an impressive achievement to say the least.
