After playing with twitter for couple of days by updating my status of “leaving office” or “arriving home”, I decided to play with twitter “by mouse” instead of “by keyboard”, which means I will stop tweeting, but start to follow others to get the info I want.

What I’m follow now – all Linux distros (Fedora, CentOS, openSUSU, Ubuntu, etc), and some nosql stuffs like Cassandra and CouchDB. I will keep looking if there is anything else I can follow.

Since I’m getting myself messed up with all sort of distros, here are something I have to write down to keep track.

To make Linux/FreeBSD distro up-to-date:

  • Debian & Ubuntu:
    alias update=’sudo apt-get -y update && sudo apt-get -y upgrade && sudo apt-get -y dist-upgrade’
  • CentOS & Fedora:
    alias update=’sudo yum -y update’
  • openSUSE:
    alias update=’sudo zypper refresh && sudo zypper –no-gpg-checks -n update’
  • Gentoo:
    alias update=’sudo emerge –sync && sudo emerge –update –deep –newuse world’
  • FreeBSD (need to have portmanager installed):
    alias update=’sudo portmanager -u’

I have some questions about cassandra that haven’t got answer yet, I’m writing them done now to make sure I won’t forget them in the future, all these questions are pretty critical for operation:

  • How does cassandra utilize multi-core? Does it have multiple threads internally, handling different requests in different threads? If the answer is no then it will be pretty ugly since I have to run multiple cassandra instances on one machine
  • Is cassandra (maybe Java) capable to handle large memory? Make it clear, can it fully utilize 64-bit machine’s memory (8G/16G/64G)? Again if the answer is no I have to run multiple instances per machine.
  • I know cassandra can replicate data from one colo to another colo, but what I understand is that they are virtually same cluster – is it possible to make two colos both have full data set, and for client request it only return data from local node?
  • Is it possible to stream updates to cassandra to another source? What I want is capturing a live data set in another data store (such as RDBMS) for other purpose, so prefer a plug-in type of implementation so that I can grab updates and send to different downstream.

Will post more once there is anything jump into my mind, and will post answers (separated blog) if I hear of any.

I’m moving back to Blackberry, so I can have something to play with to kill time.

It seems Blackberry’s application improved a lot, the UI is much more convenient and functionality is rich enough. I’ve installed gtalk, Yahoo messenger, and Live messenger, gmail, twitter, wordpress etc, and still trying to find more fun things.

The wordpress application is really cool, it could be the best wordpress app I’ve ever used.

I know the company is not doing quite good recently, or maybe we should say it’s in trouble now, but this does not mean you can do stupid things like this –

Somebody posted a job description for his friend to an internal mailing list, I do hate behaviors like this. Just don’t understand what’s in their mind.

I didn’t find any HR policies against this, but I will keep looking.

Finally I finished it, the quality should be pretty bad as I can tell.

I didn’t do much in year 2009, it’s a pity to both the company and myself, wish things can turn better this year.

I’m thinking of getting my home development environment another plan – instead of running couple of VMs on a single big box, maybe I can use couple of small computers to get things done.

This could be possible after checked online, though price may be higher. I’m still looking for single board computer/client computer that are as small as a CD box (or a little bit bigger), does not have to come with a disk as I can run NFS for it, and it does not have to be x86 based as I can run Linux on almost all sort of CPUs.

Will see.

It seems more peer feedback requests are coming, guess managers are trying to catch up the schedule as it was said today is the last day for asking for peer feedback.

Got 3 so far, done one, so 2 left plus self-assessment and manager feedback.

Just wish nobody’s going to send me more in the coming hours.

New year again so I changed my password, but this time seems I picked a bad one.

6 characters need to be input by left hand on keyboard, while only 3 are on right hand side, and left hand is not that good at inputting :(. However, I cannot come up with any other good idea for a password so I have to leave it as-is for sometime.

Maybe after a while once I’ve input enough times, I will feel better.

I was planning to get a bigger (52″ LCD or even bigger) TV in the living room, and move current 26″ CRT to bedroom, this can help me get rid of the bad habit of holding my laptop for all the time, especially before going to sleep.

However, after reading recent news I think I will hold the purchase for some time – news are talking about TV maker and cable providers could make 3D programs available for residential subscribers, which sounds really attractive.

I’ve booked two set boxes from Direct TV, I don’t want to waste the converter so I did some cabling, and hook one of them up with the desktop. The quality is not that great as I can only use it as analog device, because Microsoft’s stupid design on Media Center (search “IR hardware not detected” you will know what it is), but good thing is that now I can watch netflix and TV in same room, and 22″ LCD display is kind of acceptable.

I will wait for another month to make sure things won’t go crazy with new TV, and I may still go with an “old” regular TV if it doesn’t look too outdated.
