If your Android phone is suffering from suboptimal battery life, you may be suffering from suspend_backoff problems. This happens when the phone is woken up by applications in quick succession, so it decides to keep the phone awake for a little while. For example, there is data to be sent over WiFi, so the WiFi connection is kept awake, which keeps the phone awake.
If you are using Ubuntu 12.04 on an older computer with a Semperon CPU, you will soon find that Flash is not working and therefore Youtube videos will not work either.
This is because Adobe has build the recent Flash versions with the SSE2 flags enabled, yet many Semperons lack this particular flag.
$ cat /proc/cpuinfo

I previously wrote about reducing CPU usage for Firefox by disabling Firebug. Later, I wrote on disabling the YSlow extension also reducing CPU usage.
Now, the laptop is able to exceed 4 hours of battery time under Kubuntu Linux 12.04:
Four hours, seven minutes:
09:37:27 localhost pm-utils: Power source switched to battery, Battery: discharging, A/C adapter: off-line
This is a quick how to for installing OpenWRT custom firmware on a D-Link DIR-835 router.
Though these instructions were tested on the DIR-835, they apply to many other router models from Linksys, Netgear, ASUS, and many other brands.

To read my RSS feeds, I use Tiny Tiny RSS, which worked fine until 21 Feb 2014.
On 22 Feb 2014, Ubuntu pushed Firefox 27, Tiny Tiny RSS stopped working, with a Javascript error. After logging in, there would be a pop up error referring to getCookie and tracing to prototype.js.
To solve this, I went back to the ESR (Extended Support Release). This was quite a few steps, so I am documenting them here.
To have better fonts in Firefox, you need to disable anti-aliasing, and clear all font caches.
Do achieve this, run the following commands from a terminal:
cd ~ rm -f .fonts.conf .fonts.cache-1 .fontconfig/*
cd /etc/fonts/ sudo mv 10-antialias.conf disabled-10-antialias.conf
sudo dpkg-reconfigure fontconfig
Now, restart FIrefox and check if the fonts look better ...
How often do you reboot your laptop?
Well, for me, I run Linux (Kubuntu 12.04), and I usually do it when a new kernel security update is released. And put it on sleep otherwise.
This means I can go for a month and a half without rebooting.
Here is a recent example, output from the "uptime" command:
14:31:46 up 45 days, 2:10, 7 users, load average: 1.45, 1.29, 1.28
Having worked with many people from India and Pakistan in the 1990s, I was often fascinated by words that sounded Arabic in origin. When asking about the meaning, they were indeed Arabic. And I could detect more words in the few Hindi Bollywood movies that I have seen as well.
Arabic influence on Hindi may have been via several avenues. One was via Farsi (Persian) as an intermediate, having been the language of the court for the Mughal emperors. Another was through Muslim scholars using these words from Arabic texts and they made their way into the vernacular.
I use a 15.6" laptop for daily work, but it is kind of heavy lugging it to conferences and talks. This is aggravated by the roller case for it which has some weight in it. Add a power supply, and other sundry items, and it becomes inconvenient when I am not traveling.
So, when I saw someone givining a presentation off of an Apple iPad, I was jealous and thought: why can't I do the same from my Android tablet? Turns out that the iPad has a display port, and Apple sells a display port to VGA adapter.
