The Unofficial Gentoo Linux x86 uClibC stage3s’

Update: The catalyst spec files are available here: https://github.com/judepereira/gentoo-development/tree/master/x86/uclibc/catalyst Following this Gentoo bug: https://bugs.gentoo.org/show_bug.cgi?id=441976 We have official experimental uClibC for x86 and amd64 stages. I will not be maintaining these unofficial ones any longer. The link to the official archives is: http://mirrors.rit.edu/gentoo/experimental/x86/uclibc/ and http://mirrors.rit.edu/gentoo/experimental/amd64/uclibc/ The uclibc experimental stages on the gentoo mirrors are all outdated(they […]

Use Ruby to Generate your Shadow Password

I was initially stumbled on creating the shadow compatible SHA-512 hash. After a little research, the answer was obvious: require ‘digest/sha2′ password = “pass@123″ salt = rand(36**8).to_s(36) shadow_hash = password.crypt(“$6$” + salt) And you now have a password hash which you can directly use in /etc/shadow

The Puppet Cyclic Dependency Nightmare

Want to see the wildest cyclic dependency graph ever? Well, here it is: After this was fixed finally, after a lot of frustration, the result was majestic:

Hacking your GoFlex Home, #3 Ideas

Well, first off the ability to just add one USB device is a little boring, I’ve been using a Belkin 4 port USB HUB, and the results are good. For cooling the GoFlex, you may want to remove the bottom cover and keep it on a laptop cooling fan or something similar, as the processor […]

Hacking your GoFlex Home, #2 UART Serial Console

Serial console? That’s beautiful when it comes to debugging. The following images are specific to the Seagate GoFlex Home, however, you may be able to figure out the connections for other Marvell SoCs. On the board: Notice that according to the picture, the bottom right last three pins are used. The junction: I’ve used extra […]

Hacking your GoFlex Home, #1 Build your KERNEL

It’s been quite sometime that I’ve got my GoFlex Home now, and it’s only recently that I’ve received my RS232 Serial USB UART Adapter. The pin connections are simple and easy, I’ll post that as well. As I’ve already got Gentoo Linux running on the Marvell SoC, I was still using the Archlinux ARM kernel, […]

recursive get from an FTP server

As we all know, downloading a directory from an FTP server over FTP over the command line is not possible. Some, have found mget to be the holy grail, I certainly do not. I was restoring my music backup from my NAS, and I didn’t want to do it the GUI way, so CLI is […]

Evidently, SEED is just a kid in the corporate world

Despite several efforts to contact SEED Infotech regarding their mishap for the past two days, they do not respond. E-mails, twitter updates, facebook posts being deleted from their end, says everything: SEED Infotech is lazy. They cannot afford to sponsor an event such as this one. What’s more, today’s challenge makes no sense whatsoever! SEED […]

SEED hits the pit again #iknowvention

SEED continues to make mistakes. So is today’s challenge: #include int main(int argc, char *argv[]) { printf(“%d”,4[“seed”]); return 0; } The answer for the above is 0, as the fourth element in the array “seed” does not exist. This is because of the index value, which starts from 0. Had it been 3, then it […]

SEED makes Blunder! #iknowvention

Alright, so I’m taking part in this SEED Infotech C programming contest, and here’s one of yesterday’s challenges: main() { if(printf(“C for yourself how it works \n”); main(); } One of the options were a) C for yourself how it works infinate times Now isn’t that catchy? Look at it clearly, there’s one pair of […]

So if you wanted to export your contacts from your phone and import them into your GMail contacts/other contact management, how would you accomplish this? It’s a little complicated, but easy once you do it for the first time. From your […]

Resetting a User’s Home Permissions

Recently I managed to mess up my home permissions, to the extent that I owned the files, but couldn’t read them. Fixing an entire user’s home directory permissions is simple and easy. # chown user:user -R /home/user/ # chmod -R u+rwX /home/user/ Done.

liferea and gmail

I bet that mail client of yours just lies there doing nothing, when its sole purpose is to inform you the minute you get a new e-mail. Well, that client just takes up more memory, to just do that, doesn’t it? What if you could just check new mail via an RSS feed? liferea to […]
