Hardware

I’m selling my IGEPv2* board. Rarely used and works perfectly.

Selling because I could use some cash and I do not have the time (or any particular use) for it anymore. It was a dev project for a project of mine.

(*) seems like my Flickr plugin is broken. > pics here.

Yay, after many months-o-slack it went finally live a few days ago. The prototype that is.

Soon in every building ! ;)

Thanks to everyone who helped out! :)

I recently bought a Xoom, WiFi version.

This will be my short review about this Xoom.

First of all, this is a Xoom made solely for Google employees. It has the Google logo on it, and a green back side. As far as I know there is no public way to get the device with these colors,

Android

I received it the day Android 3.2 got released. First thing I did was upgrade from 3.0.1 to 3.1 and then to 3.2.

Oh lord. I seem to have entirely forgotten One’s, euh, uptime-day. (Yea, blame my business trips in Beijing & San Francisco for that).

But… Over 2 years! yay

I talked about MRTG stats for Squid in the past but apparently forgot to include the .mib file.

So, here it is. Download this file and put it in /usr/share/squid/mib.txt.

I don’t quite remember where I found that mib file. Probably included with Squid on Gentoo or the world wide web… But I couldn’t find it on Debian, so here it is. And be sure to add these lines to your Squid config:

I tend to restart OpenVPN a lot due to config changes. As a result, this brings quite some issues to MRTG (or more precisely, SNMP), due to the fact tun devices change of ID.

A while back, I found a quick fix for this; rename the interface targets from their respective ID to their name:

Target[eth0]: 2:public@localhost

becomes

Target[eth0]: #eth0:public@localhost

#
# Eth0 stats
#
Options[eth0]: growright, nobanner, pngdate, nopercent, noinfo
Target[eth0]: #eth0:public@localhost:
SetEnv[eth0]: MRTG_INT_DESCR="eth0"
MaxBytes[eth0]: 1250000
Title[eth0]: Traffic Analysis for deng
PageTop[eth0]: <H1>Traffic Analysis for deng (eth0)</H1>
#
# Eth1 stats
#
Options[eth1]: growright, nobanner, pngdate, nopercent, noinfo
Target[eth1]: #eth1:public@localhost:
SetEnv[eth1]: MRTG_INT_DESCR="eth1"
MaxBytes[eth1]: 1250000
Title[eth1]: Traffic Analysis for deng

As you noticed… Or perhaps didn’t notice, I’ve started using a new, simplistic theme a couple of days ago.

Kinda thought it might be too simplistic (I’ve hidden the sidebar, there’s no search or archive, etc), but I started to, you know, get attached to it.

So it’s here to stay, for a year or something. I guess.

I’ve also noticed that the long load times on my blog were WP_Buzz’s fault. Nice plugin, but 15 to 45 seconds of load time per uncached page wasn’t really worth it. Hope it can be fixed.

I received a question about creating a RAMFS for Mac OS X’ /tmp folder, so I’ll post my reply here as well.

It’s really simple;

1. Open Terminal (Applications -> Utilities), type "sudo su" and enter your user's password.
2. Create a new file in /Library/LaunchDaemons, like this: "nano -w /Library/LaunchDaemons/com.yeri.ramfs.plist" (you can rename yeri to whatever you like)
3. And insert following content (ctrl+x to save - y - [enter]):

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" 
"http://www.apple.com/DTDs/PropertyList-1.0.dtd">
<plist version="1.0">
    <dict>
        <key>Label</key>
        <string>com.yeri.ramfs</string>
        <key>ProgramArguments</key>
        <array>
            <string>/var/root/ramfs.sh</string>
        </array>
        <key>RunAtLoad</key>
        <true/>
    </dict>
</plist>

4. create a second file in /var/root/, like this: "nano -w /var/root/ramfs.sh"
5. And insert following content:

#!/bin/bash
ramfs_size_mb=64
mount_point=/private/tmp
ramfs_size_sectors=$((${ramfs_size_mb}10241024/512))
ramdisk_dev=hdid -nomount ram://${ramfs_size_sectors}
newfs_hfs -v ‘Volatile HD’ ${ramdisk_dev}
mkdir -p ${mount_point}
mount -o noatime -t hfs ${ramdisk_dev} ${mount_point}
chown root:wheel ${mount_point}
chmod 1777 ${mount_point}

6. chmod +x ramfs.sh and reboot. Check in Terminal with “mount” or “df -h” is everything is fine. To hide the disk icon on your desktop, check my old blog post.
7. In case Mac didn’t do so already, you might want to link /tmp to /private/tmp: “rm -r /tmp && ln -s /private/tmp /tmp”.
8. Should be it !
