No worries! I’ve written exactly the thing you need :p

Just use the following box!

update #2 [2010/05/17]: uploaded my updated config file, now using ` as my prefix key

I gave tmux a try yesterday.

Clean config file, thorough documentation and a few nice touches here and there (i.e. better, persistent window splitting) make it a nice alternative to screen, but the biggest difference lies in memory usage. Screen can easily eat up to 40-50mb with just a few windows open, but tmux has yet to reach the 10mb mark!

You may argue that ram is cheap these days, but when you’re on a 360mb VPS ram matters

I did find a few bugs/annoyances, for instance if you add set-option -g default-terminal “screen-256color” in your config file, tmux stops evaluating the #T variable.

I hacked my way out of this one by adding the following in my .bash_profile instead:

[[ $TERM == "screen" ]] && export -p TERM="screen-256color"

Turns out that’s not tmux’s fault but bash’s, I’ll have to create a patch for that as well If you have the same issue, you can use the above hack as a temporary fix.

Also version 1.2 does not provide a way for you to customize the colors used on window titles with alerts (either monitored or when the bell is active), but I patched that and sent it upstream

You can find an ebuild with the patch in my overlay, wirelay (layman -a wirelay ).

The patch was accepted upstream so it’ll be in the next release.

My tmux looks like this:

and with some split panes:

finally, below is my (updated on 2010/05/17) tmux.conf config file, used in the above screenshots.

I decided to use ` as my prefix key, its really better than hitting ctrl-a all the time

# ` is an interesting key for a prefix
set-option -g prefix `
# set-option -g prefix C-a

unbind-key C-b
bind-key C-a last-window
bind-key ` last-window
bind-key a send-prefix

# we might need ` at some point, allow switching
# we can also send the prefix char with `-a
bind-key F11 set-option -g prefix C-a
bind-key F12 set-option -g prefix `

# 0 is too far from `
set -g base-index 1

# set-option -g default-terminal "screen-256color"
set-option -g mouse-select-pane on
set-option -g status-keys vi
set-option -g bell-action any
set-option -g set-titles on
set-option -g set-titles-string '#H:#S.#I.#P #W #T' # window number,program name,active (or not)
set-option -g visual-bell on

setw -g mode-keys vi
setw -g mode-mouse on
setw -g monitor-activity on

bind e previous-window
bind f next-window
bind j up-pane
bind k down-pane

set-option -g status-utf8 on

set-option -g status-fg white
set-option -g status-left-length 40

set-option -g pane-active-border-fg green
set-option -g pane-active-border-bg black
set-option -g pane-border-fg white
set-option -g pane-border-bg black

set-option -g message-fg black
set-option -g message-bg green

#setw -g mode-bg black

setw -g window-status-bg black
setw -g window-status-current-fg green
setw -g window-status-alert-attr default
setw -g window-status-alert-fg yellow

set -g status-left '#[fg=red]#H#[fg=green]:#[fg=white]#S #[fg=green]][#[default]'

set -g status-right '#[fg=green]][ #[fg=blue]%Y-%m-%d #[fg=white]%H:%M#[default]'

set -g history-limit 4096

# `+r reloads the configuration, handy

# to teach spamassassin:
isbg.py --imaphost [HOST] --imapuser [EMAIL] --noreport --teachonly --learnspambox INBOX.spam --learnhambox INBOX.read-mail --spamc


I have to say, I was impressed. You chat (and it updates) in real time. You can embed stuff like Google maps, Google searches and Youtube videos (and the list will surely improve since it seems to support Google gadgets). It really feels like next-gen email combined with a messenger

It is called a preview for a reason though. Sometimes you need to refresh the browser and at other times your waves go crazy and you can’t use them for a while. It also tends to eat up lots of CPU if you have a lot of participants and media content. But its Google, so we know its all going to be fixed really soon

Below you’ll find an embedded wave I’ve added using the Wavr WordPress Plugin (you need to have a Wave Account).

Well done Google!

I really really really wanted a variable-width theme and something I will be able to call my own.

So I picked this nice clean theme (made by openark.org) and I’m going to build on it over time until I’m satisfied Hopefully you people will find it readable and easy to navigate

While we’re on the themes topic, today I added the WPtouch module that provides native-like navigation to my blog from iPhones. I discovered this pretty good plugin after navigating to www.elkosmas.gr with my iPhone

As you probably know, firefox keeps track of everything you visit while you browse the web infinity, then allows you to quick-search that history just by typing in its awesome bar –err, address bar

Unfortunately, after a while the whole thing slows down and gets a bit annoying. So what Comzeradd tried was to move ~/.mozilla (which includes the history database) on a tmpfs mount.

The difference is staggering! Searches are snappy again and even firefox itself feels faster!

Comzeradd offers a script that syncs your tmpfs ~/.mozilla with a folder on your hdd to make sure you won’t lose your data on reboot/shutdown/powerfail.

I took this a step further by creating a firefox wrapper script. After you move your ~/.mozilla folder to a safe place, this script makes sure that your data is always synced between the tmpfs folder and your hdd folder on a fixed interval.

what the script does, in steps:

1. check that we don’t have any stale ~/.mozilla folder
2. rsync our hdd copy of .mozilla with our tmpfs
3. launch a background process that syncs any changes on the tmpfs .mozilla folder back to our hdd copy every one minute (adjustable)
4. launch firefox
5. when firefox ends, kill background process and sync back to the hdd one last time

To use the script, you’ll first need to mount tmpfs to a folder. On my laptop I have my /var/tmp as tmpfs (useful for gentoo emerges too). To make /var/tmp a tmpfs folder, you need to edit your /etc/fstab file and add the following line:

tmpfs              /var/tmp    tmpfs  size=768M,mode=0777         0 0

You should adjust the size= option based on the ram you have available.

Then just mount the “partition” with:

mount /var/tmp

and execute the script

chmod +x speedfox

speedfox

Thats it! This simple process gives firefox a real boost!

If you start speedfox from a terminal, you can see the rsync info at the beginning and after each minute =]

You can get the script here.

Don’t forget to edit it, read the instructions and configure its variables!

Thanks are in order for all those great guys and gals who made this weekend special, the “ATEI of Larisa Linux Team” =]

Everything was well organized and planned out (ok, those pigeons were added value, but you have to admit they were funny :p) and I am sure everyone had a great time. I certainly did

A lot of pictures are now available from both days for your viewing pleasure. View them in picasa or click the photo on the left

Don’t forget to tag yourself so other people can find you

update: I have uploaded the full resolution JPEGs in ftp://linuxteam.cs.teilar.gr/fosscomm/wired_linuxized.com/ for your viewing (and printing) pleasure.

We (the gentoo team) hosted a workshop showing off gentoo’s installation process and portage features using the gentoo handbook as a guide. Time was limited and we didn’t manage to finish it, but I think we touched some people when we explained how portage and its USE flags work

Next up is a Gentoo presentation tomorrow. Comzeradd and Tampakrap will present the Gentoo Project, analyze its advantages and disadvantages and show off how easy it is to create an ebuild for a new package, or add a patch to an existing one

Videos from fosscomm’s presentations and workshops will be available shorty and I’ve also taken some pictures which I will upload tomorrow =]

Welcome to my new blog. Previously available @ http://linuxized.blogspot.com, I’ve moved my meaningless typing to a more private space.

Hopefully this will work out well – if not… I guess I can always turn back to blogger..
