Buffalo needs a happy song today.
Category: music
The constantly dragging workload and grey skies are getting to me. What I need is this happy song from Boney M to pick me up and accelerate on my work so I can clear some more hurdles (read: chapters).

Lay your problems on the floor, clap your hands and sing once more.

Analyzing blame
Category: linux
For a LOOOOONG boot-up time. Seriously, I could put the kettle on and have it reach a boil, or be halfway on my way to my office by the time the login screen comes up.

Why on earth does the sendmail service need to run? I don't even run a mail server.

hey, I am not messing with anything right now. Some recent updates have not been so great. Gnome Shell keeps consuming memory till it reaches 2GB or more after a few hours and it brings everything to its knees. I found out that my Wacom tablet not functioning is not the fault of the stylus or the tablet but because of some crazy stuff that gnome-shell is doing - probably being a memory whore.

Anyway, the point of all that is rebooting solves several issues. It clears up the memory once more, the stylus works once more, R does not crawl etc. But of course then I have to face a 2 min boot sequence.

I am going to just take your advice and not do anything. But yeah, instead of messing with the system, I actually think I am going back to vanilla ubuntu after I am done for good.

I love (e:Paul)'s advice!
paul - 02/24/12 15:49
You can turn off sendmail but I wouldn't start messing with your machine services right now. Just live through the 60 seconds boot time until you dissertation is done. Otherwise, you are bound to fuck it up and have way more downtime. Here is a great overview of working with systemd :::link:::
paul - 02/24/12 15:44
I lied mine says it took 50 seconds, I swear its faster than that. Maybe the last boot was slow, I did have a kernel update.
paul - 02/24/12 15:43
you can disable whatever services you dont want. This is even more interesting systemd-analyze plot > graph1.svg
paul - 02/24/12 15:38
That is so crazy. My system boots in like 10 seconds. Maybe its worth investing in an SSD.

Weird business names
Category: the odes
And in the category of weird business names, I got this email today:

"Price Protector is now Eyeona"


Like in a wild hyena laugh? What does bargain-hunting have in common with hyenas? Is that supposed to be a riddle? I know I can follow the links on that email and read the back-story and all that in the time it has taken me to write this out here. But really, first impressions are the worst and the most fun.

The useful Android app list
Category: android
In addition to the default apps that came with the Nexus one phone, I have the following additional ones installed:.
  1. estrip
  2. ezPDF Reader
  3. File Expert
  4. GNotes
  5. Opera Mobile
  6. Pomodroido
  7. Maildroid
  8. Quickoffice
  9. Wifi file transfer

Out of that list, I see these as apps with a ton of access and with the potential for troublemaking
  • Wifi file transfer
Storage (modify/delete SD card contents)
Network communication: full internet access, view network state, view Wi-Fi state
  • Maildroid
Your location (coarse- network-based location, fine GPS location
Your personal information: read contact data, read sensitive log data
Storage (modify/delete SD card contents)
Network communication: full internet access, view network state,
Phone calls: read phone state and identity
System tools: prevent phone from sleeping, automatically start at boot
Hardware controls: control vibrator

MAN! that is a hell of a lot of permissions. But this app is SO useful because it keeps me updated about my work email - a paleolithic MS Exchange server 2007 based system

I think these came with the phone. I don't use them and want them out. Someday, I will root this phone and chuck them out.
  1. Amazon MP3
  2. Car Home
  3. Facebook
  4. Goggles
  5. Magic Smoke wallpapers
  6. Music Visualization Wallpaper
  7. Twitter

Huh? What do these even do?
  1. HTC Radio Info
  2. KickBack
  3. Google Backup transport
  4. Google One time Init
  5. Google Partner Setup
  6. Pico TTS
  7. SoundBack
  8. TalkBack

Android Viruses
Category: i-tech
Traditionally, it has been very tough or very unsatisfactory for virus-creating hackers to target the Linux OSes because the field is so fragmented. There are as many distributions as there are stars in the sky... and possibly more.

I was recently wondering about the situation in Android because the field is somewhat unified with limited number of variants. Anyone who writes an application can get entry into the Android market and peddle their apps. This is great for reaffirming the open source and free nature of the Android operating system but is quite a nightmare in terms of security.

And sure enough, I spotted this article:

I am kind of spooked. I try out random apps all the time and I certainly am one of those people who just says yes to the permissions screen. No one, apart from expert hackers can actually tell whether or not an app is going to cause extensive harm just by looking at them in a cursory fashion. But everyone can definitely pay more attention when it comes to what apps they choose to install.

I am going to start a running list of apps I have on my android devices here, I started this for chrome apps a while back but it has fallen into oblivion. I need to revive that as well. Hacking chrome is somewhat tougher but the basic playing ground is the same. I think, for non-hackers, knowledge about the apps they are using is 3/4ths of the battle against the viruses. The other 1/4ths is resisting temptation to download chunks of the whole marketplace willy nilly.
