Updating OpenWRT packages on a USB stick

Posted by & filed under Uncategorized.

With opkg.conf configured with a usb destination I can install packages with:

But sometimes, because files are not where the system expects the packages will not run once installed. A simple way to fix this is to run the following command after installing something to USB:

I made it a quick script so I can just run it to sync everything up.

gnokii — phone interface

Posted by & filed under Server Admin.

gnokii provides tools and a user space driver for use with mobile phones under various operating systems (most testing is done under Linux but also Solaris, *BSD family and MS Windows families are known to work). gnokii allows you to communicate with the phone over the serial cable connection, usb connection (support depends mostly on the operating system level support), infrared connection and bluetooth connection.

You can send SMS, receive them and save them in the phone, read and write to the phonebook, initiate and answer calls and more. Pretty cool and just what I need for a a GSM alerting project at work.

Mosh: MObile SHell

Posted by & filed under Networking, Server Admin.

Remote terminal application that allows roaming, supports intermittent connectivity, and provides intelligent local echo and line editing of user keystrokes.

Mosh is a replacement for SSH. It’s more robust and responsive, especially over Wi-Fi, cellular, and long-distance links.

Mosh is free software, available for GNU/Linux, FreeBSD, and Mac OS X.

Installing git on a cPanel server

Posted by & filed under Server Admin.

I needed to install git on a cPanel server recently. After adding the appropriate EPEL5 or EPEL6 repo (fedoraproject.org/wiki/EPEL), you should be able to simply do a:

But yum kept reporting a unmet dependency — a Perl-git package — even though I verified the missing package is actually present in the EPEL repo. After a bit of digging, I found cPanel has set yum to exclude any packages with Perl in the name. Simple enough to fix, but aggravating:

Remove “Perl*” from the exclude line and save.

Jump back into the yum.conf file and add the perl* exclusion back in so yum does not eat cPanel’s braiiiinnns….

Done!

QR Art Codes

Posted by & filed under Programming, Software.

QR codes are 2-dimensional bar codes that encode arbitrary text strings. A common use of QR codes is to encode URLs so that people can scan a QR code (for example, on an advertising poster, building roof, volleyball bikini, belt buckle, or airplane banner) to load a web site on a cell phone instead of having to “type” in a URL. Encoding a image in the QR code is a interesting topic.

Quantum Random Number Generator Available Publicly

Posted by & filed under Uncategorized.

Reliable and unbiased random numbers are needed for a range of applications spanning from numerical modeling to cryptographic communications. While there are algorithms that can generate pseudo random numbers, they can never be perfectly random nor indeterministic.

Researchers at the ANU are generating true random numbers from a physical quantum source. We do this by splitting a beam of light into two beams and then measuring the power in each beam. Because light is quantised, the light intensity in each beam fluctuates about the mean. Those fluctuations, due ultimately to the quantum vacuum, can be converted into a source of random numbers. Every number is randomly generated in real time and cannot be predicted beforehand. So if you need some really random numbers, use the link below!
