Installing japanese Input

2010-05-20T02:29:00.001-07:00

Oh, so...Yeah....Here is this. I made it a while ago but never linked it here. I suppose I should do that in the future.

This is me installing Japanese input support on ubuntu 9.04. The steps are pretty much the same for 10.04 and it seems to work for net-books as well.

Video is probably easier to follow if you pop it out, like it's hot; http://www.youtube.com/watch?v=BAA52SGzhL4

There is no sound because I always sound like a huge nerd over microphone

List apps. using an internet connection

2010-01-22T11:22:00.001-08:00

Show apps that use internet connection at the moment

typing in lsof without any arguments is a terrible mess, however using some of the arguments in the link makes some pretty output

Go ahead and look at the manuals for lsof, ss, and netstat, then close them....They're all really long....Reading is for chumps.

What type of ram do I have?

2009-11-12T19:50:00.000-08:00

Problem: I wanna look at RAM I may be able to buy but I don't know what memory type I already have and even though my computer is right next to me it is still to far for me to go to to open up and see what type of ram it takes.

System details:
Ubuntu 9.04
uname -a: Linux Moneque 2.6.31-14-generic #48-Ubuntu SMP Fri Oct 16 14:04:26 UTC 2009 i686 GNU/Linux

Solution:
use lshw

tl;dr....sudo lshw

*nix Systems come with a bunch of ls things; lshw, lsusb, and lspci are a few that I know of. lshw will list everything your computer recognizes as part of it, though I donno if that's printers and the such as well. lsusb Will list the details of your usb bus bits. lspci Will list your pci devices, video cards and sound rcards, this includes pci-e.

to use lshw you can fire up a terminal and type


lshw

That will, at least on my system, probably cry about wanting to be super user.....


aggitan@Moneque:~$ lshw
WARNING: you should run this program as super-user.

       description: Motherboard
       physical id: 0

The information this displays is good enough for somethings, like if you want to know a bit about your processor and so on. However some details, like the memory type will be omitted.

To fix this we run it with sudo....


sudo lshw

and that should give us more details.....


aggitan@Moneque:~$ sudo lshw

Now, depending on your system you may get more information that can be displayed on your screen at any one time so you'll need/want to pipe the output to a file.


sudo lshw >> somefile

If the file doesn't exist it will be created and written to.

So as far as the memory problem goes we want the segment that starts with
*-memory, it will tell us: where the modules are, how big they are, and what type they are.

The important parts here are the descriptions, it looks like my system is rocking DDR2 and the modules I have are running at 800MHz. So I would want to look at getting more DDR2 RAM that operates at 800MHz

Huge Log Files

Solutions:
-- Backup, remove, and recreate the files
-- Backup and use the built in tool: truncate
-- Delete everything.

Let's do it:
the filesystem full error message will tell you which filesystem is full, to view details about your other filesystems use the df command


%df -h
Filesystem     Size    Used   Avail Capacity  Mounted on

Looks like our /var directory is full. There are few things, that I know of, that would grow and cause this directory to fill; the log files.

use the cd command to cd to the directory the logs are located at


%cd /var/log/

use the list command with the proper flags to view files and their human-readable sizes

Looks like we have some pretty large files there, the G means gigabytes and the M means megabytes. While it is generally believed that bigger is better this is a bit much.
We can either delete these two files and recreate them or shave off some of the extra fluff.

Take a quick look at the manual page for truncate. Then put on your robe and wizard's hat. Once you're set You can speak the magic words:


truncate -c -s -900m httpd-access.log

And this should chop your file down a fair bit. You can keep using this command and modify the number until you get the file down to what you feel is a reasonable size.


%ls -alh

-rw-r--r--   1 root  wheel     7.3M Oct 11 00:17 httpd-error.log

All that's left now is to take off the robe and wizard's hat....and put it all away...

Project Outline: N.O.’ing

2009-09-06T03:20:00.000-07:00

I want to make a conjugation practice program thing for Japanese. Japanese programming is pretty systemic so it should lend its self to being programmed by me fairly easily. I’m naming it “Not only ‘ing” and abreviating it as: N.O.’ing
