Google Translate Now Support Bahasa Indonesia

Google Translate

I use Google Translate often for translating from Dutch to English as I’am currently working for a Dutch company and some of the documents are in Dutch.

Several days ago I noticed that Google Translate now support translation from/to Bahasa Indonesia. I tried several times and the translation is good enough although still a lot of words not translated or the translation is not correct.

I’m quite happy with the addition of Bahasa Indonesia as it will help a lot of Indonesian to understand English language.

Xen VPS can’t initialize iptables table ‘filter’

If you using HyperVM and get this error message after upgrading your dom0’s Xen kernel:

iptables v1.2.11: can't initialize iptables table `filter': iptables who? (do you need to insmod?)

It means that the library for the kernel is not copied yet to the VM. To fix this simply copy the new kernel library from /lib/modules/<new kernel> to VM’s /lib/modules directory then restart the VM.
