"Trigger" event button through serial rs-232 port

Posted 03-09-2011 at 07:32 AM by matiasar

Serial ports seems to be part of the past, but surely is one of the most straight ways to communicate a linux box with the external world.
Recently I need to use a single button which a user could push and trigger some event, in my case a bash script to scan a document.
I wanted to do a "headeless" print and scan box (of course running Linux), where a user could just print documents (through samba+cups) and scan documents, then the scanned documents are available to local...

Open door to android.

Posted 03-08-2011 at 05:57 PM by peonuser

My brother bought a B&N Nook and did the 2.x android thing to it. He really loves it. He stated that it had about 7 hours usage available per charge. Wifi works with his android version. He also swapped out some of the apps such as the browser to get better utility from them. More incentive to set up a android development environment. He can test apps without me having to purchase a device with android on it.

Sometimes I unplug my regular network from provider box so I can do...

Hello and Goodbye!

Posted 03-08-2011 at 05:15 PM by tuxandpucks

Welcome and Goodbye!
You know who you are. Yes, you, who said hello and turned around without ever giving me another consideration.

Too many times you freely grab my excited possibilities and open-considerations only to say, nope, not for me. Why? Oh, darn, you see something different than you are used to. Oh, my! So sorry to inconvenience you and your stubborn, stuck, dug-in, overpaid, under-produced, not-so-safe system.

Dare I say that many tools, gadgets,...

Slackware-13.1-Hacks-Google Chrome Hardening

Google Chrome Web Browser Hardening

These are the settings I use on Google Chrome, however you may go more stricter or looser with your security settings depending on your needs. I tend to disable any passwords saved, suggestions for searches, etc. Also, you can remove a lot of junk by using a hosts file (see the Hosts File Hack) which will disable banners, ads, etc.

The current version available from SlackBuilds.org is google-chrome-9.0.597.84, but since the snapshot...

Slackware-13.1-Hacks-Su/Sudo Hardening

Posted 03-07-2011 at 12:20 PM by arniekat

Su/Sudo Hardening Tutorial

In a default Slackware 13.1 installation, you create a root user with a root password. Normally, I create a regular user who is a member of the following groups: audio, cdrom, floppy, netdev, plugdev, power, users, video and wheel. The thought being that only members of the "wheel" group should be allowed to su (switch user) to root to do administrative work. Here's how it works:

bash-4.1$ su
Password: <root_password>...
