the first servers are back up and running and working unexspected well under xen.

basicly we have on server with 2 cpu and 4 gb ram and running:

  • oracle server
  • mysql server
  • mysql server and apache for monitoring using cacti of the network
the load is fine sofar and we are migrating now our other boxes to xen too to make the management and the backup of complete servers easier.

idea:
  • pdc, ldap
  • cvs
  • devel oracle server
  • production jboss
  • devel jboss
it should take only 2 days as soon as i figure out where I store all the data from the pdc.

the bitch is dead,

the bitch in this case is a server called venus and decided 2 days ago to stop working. Sadly this is my database server containning our production database...

so it was time to find out if the backups are working. After 8h I finally had a temporaery database server up and running with a minimal loss of data ( arround 300 samples, are calculating right now again).


now I planned to create a new server using:

- gentoo as base system
- xen for virtualisation
- lvm for storage management
- redhat/centos enterprise linux as virtual machine for the oracle database
- minimal gentoo as virtual machine for the application server

the final plan is to migrate all my server to xen with an atttached nas to allow the migration of servers without any downtime.

whats up and running on my wizard

  • bluetooth headset motorola HS820
  • synchronisation over bluetooth
  • synchronisation over usb
  • skype - headset not working yet and its kinda slow
  • email
    • gmail synchronisation over pop3
    • outlook synchronisation using active sync
  • gprs works but took forever to disable it, cause trys all 5 minutes to connect to the internet
  • wireless lan works fine, got it to work in a/b/g with a registery hack
  • voice dial works over bluetooth and freehand also
impression sofar
  • once you are able to kill all background tasks its fast, but slows down when you have more than 5 programms open
  • never ever go into the windows folder and say sort by type, 20 minutes later it was finally done...
  • phone works quite well
  • active sync needed to be update to avoid that outlook crashed, version 4.2 is ok
  • the bluetooth stack is a little big buggy, sometimes hard to get the synchronisation to work
  • battery live is ok, 24h bluetooth on and still 50% left

one of my new toys. The cingular 8125 also known as t-mobile mda ( think the german model is mda III ) is quite nice and the speed is ok. Just the display is like always way to small. The size is ok sofar. Could be a little thinner. But in this case I would'nt have the keyboard, which is the nicest part.

The synchronisation works with the x60 and I'm working on the synchronisation over bluetooth right now. Suprisingly my headset connects with both of the toyes easily, but sofar I'm not able to get it running with the phone. Posted by Picasa

the daily joke appeared again.

I finally received my new laptop and it's damn nice. Only that the order was wrong again.

- they delivered 2 more batteries than I ordered and they don't fit at all...
- they delivered only 1 GB of ram insted of the ordered 2 GB

why is it so difficult to get an order once right .

anywa sofar I'm really satisfied.

- very light
- display is very bright, the first time I actually work with a display where I reduce the intensity
- battery liftime is arround 4h with wifi and bluetooth on
- pretty fast, gotta test how it performs under java
- that you need the docking station for a second battery/hd or a cdrom kinda sucks, but when did I ever need a cdrom anyway
- it has a sd slot, so perfect for my camera

right now I look at smart phones and found one thats nearly perfect

the mda from t-mobile/cingular for 249$ before taxes. so in total with activation fee and so it should be arround 300$. The size is ok, little bit larger than a motorola razor.

the main question is do I need it or does it another phone too?

basicly any phone thats not a flip phone cost arround 100$ and you can call and play mp3's with it.

The mda can more and has nearly the same size.

- full pda
- plays mp3
- extension via mini sd card -> gotta sell my sd card and switch over to mini sd in case I buy it ( i think I go shopping soon)
- can use wifi to browse the internet ( and automatical receive my emails all 45 minutes)
- i can write programms for it what makes it really interessting to maintain my servers
- with its full sized keayboard i can work over ssh, what makes it really sweet

mhm I think about it, ist only 150$ difference to a normal phhone. (I also could spend this 125$ on a short trip with my girl...)

we will see... I have 600$ left for this month and the half is already gone.

I also came to the conclusion that I don't need a heart rate monitor and a cadence monitor. I could ride my bike quite well with out it at the weekend...

i hate computer/cellphones/programming/databases right now

since 30 days I got every damn day another problem:

- laptop dies
- wrong parts get delivered
- phone died
- all server died at work after a power failure
- database drives me crazy with the stupid 32bit limitations
- barley any storage space and figthing for every byte here
- eclipses crashes all 5 minutes for no special reason

at least I made a nice 60km bike tour on sunday and went to bed at 3 pm, cause i was so tired. It was supposed to be a nap, but i slept until 2 am ( maybe I should have slept from saturday to sunday more than one hour...) and now I'm sitting at work because there are samples what need to be calculated by this afternoon. So no rafting for me :( (ok I wasn't sure if I go anyway, but thats not the point)

so we will see what comes next. Now I'm in the hussle to find a new phone...

smartphone or normal phone. I want basicly

- mpg3 player
- wifi
- pda
- sd slot

for not more than 300$ and for a model not older than 6 Month.

the only thing that has the features are:

palm treo 700p except for wifi
mda except for sd slot ( what should I do with mini sd, I want one standard)

at least my laptop is supposed to come today...

an crazy idea...

my girlfirends birthday is at the 21st of setptember and she decided to celebrate in San Diego Area. Now I had the idea to go there by bike and drive back by car. Basicly riding down the route 1 should'nt be to bad.

Its about 500 miles. So I need to cover 50 miles a day, which should be doable. I will make a test ride this weekend from davis -> winters -> berryessa to see how well I can handle mountains. This is basicly a distance of 70 miles and should be doable in close to 4 hours for an untrained person like me.

6 more days until I get my new laptop, I can't wait. Without it I can barley do anything,

- no pictures cause can't edit them
- no internet at home
- no email at home
- can't work at home (writing documentation and papers)

but a couple of days I already recieved my battery for my new toy...
and yester day two more batteries...

laptop = 0
battery = 3

so we see what our ordering system else got wrong. I don't get it whenever I order something over this system I get the wrong stuff like

- dell server for database purpose = no scsi adapter and cable
- storage server = wrong network cards
- nas = suprisingly no mistake
- workstation = wrong harddisks
- minimacs = wrong fire wire wires

so 1 out of 5, damn thats sad...

oh by the way new project: BinBase Cluster System
