It’s working great with SqueezePlay and MythTV-frontend!

If you want to use MythTV, I can recommend EasyStroke to control it by gestures.

As said in http://www.flattermann.net/2010/04/android-on-o2-joggler/ I’ve tried to install Android on the Joggler/OpenPeak.

In the last post, I said that Sound and Wifi did not work yet.

Well, that’s solved by now.
You can use Sound and Wifi on the Joggler now!

BTW: The sound quality is pretty good!

What’s your first thought?

Right: Why didn’t they install Android on it?

I was able to get one of these gadgets from O2/UK for a discount price of 49GBP, so couldn’t resist.

In the meantime, I was able to install Android on the Joggler!

See the JogglerWiki for instructions:

(BTW: It also contains info about Ubuntu and Meego on the Joggler!)

Not everything works yet, but it is a start.

• It boots (albeit GUI is still slow)
• Ethernet works
• Touchscreen works
• /sdcard & /data works
• And the most important thing: SqueezeCommander works!

Wifi & Sound are still missing, though.

[Update 2010-04-24: Wifi & Sound are now working!]

There’s a great project to port Android to x86!

They offer a LiveCD that you can try without changing anything on your PC.

Furthermore, you can even install it on your PC/Netbook!
It should already run on e.g. many Netbooks like the Asus EeePC.

I’ve installed it in a VirtualBox under Linux and it runs pretty well.

Some hints:

• The Windows key acts as HOME key
• The Context key (on the right of the right Windows key) acts as MENU key
• ESC acts as BACK key

To keep the settings in a VirtualBox permanently, you need to create two partitions:

• A data partition (500MB should be sufficient)
• A SD card partition (as large as you need)

You need to add the partition identifiers to the boot kernel line, see also:

Have fun!

In this case, you should take a look at the SheevaPlug embedded PC.

It’s not exactly very pretty, but it’s cheap (~100$) and it serves it purpose. It uses a 1.2GHz ARM CPU, 512MB RAM and uses as little as 2.3W (idle) to 7W (100% CPU usage).

You can attach an external USB drive to store your music on and install the SqueezeBoxServer to serve the music to your SqueezeBoxes.

Thomas Rühl created some images for the SheevaPlug that include the SqueezeBoxServer. His project is called SqueezePlug. It makes it very easy to get the SBS on SheevaPlug running.

Of course, it’s perfectly controllable with your Android mobile using SqueezeCommander.

It’s very nice to have internet-everywhere via the internal UMTS G3.5 modem, and this is very easy to accomplish with (Debian) Linux.

I’ve written a small HowTo that describes the necessary steps.

Introduction

As I’ve already described in other blog articles, the Asus EeePC 901 Go is a great piece of hardware, fast and reliable with encrypted disks, and for me the perfect travel companion. Since I own this Netbook, I virtually never carry my old, big Notebook with me when I visit my customers.

Of course I’ve installed Debian Linux (Lenny) on the EeePC, so that I have my familiar desktop environment on the Netbook.

HowTo configure UMTS via the internal UMTS modem

First of all, remove the battery of the Asus EeePC 901 Go and insert the SIM card of your provider into the  SIM slot. Reconnect the battery and startup your Debian system…

Activating the internal UMTS modem is pretty simple:

(You can skip the first steps if you want, they are just to make sure that the drivers are loaded correctly.)

• Make sure the correct kernel driver is loaded:
  • Open a terminal and enter the command:
  • dmesg | grep HUAWEI
  • The output should look like this:
  • [    5.426460] usb 5-6: Manufacturer: HUAWEI Technology
    [    5.417153] usb 5-6: Product: HUAWEI Mobile
• If that works, check if the USB modem is correctly bound:
  • dmesg | grep GSM
  • The output should look like this:
  • [   12.478987] usbserial: USB Serial support registered for GSM modem (1-port)
    [   12.487549] option 5-6:1.0: GSM modem (1-port) converter detected
    [   12.496203] usb 5-6: GSM modem (1-port) converter now attached to ttyUSB0
    [   12.504920] option 5-6:1.1: GSM modem (1-port) converter detected
    [   12.513610] usb 5-6: GSM modem (1-port) converter now attached to ttyUSB1
    [   12.525525] option 5-6:1.2: GSM modem (1-port) converter detected
    [   12.534178] usb 5-6: GSM modem (1-port) converter now attached to ttyUSB2
    [   12.551416] option: USB Driver for GSM modems: v0.7.2
• You can see that the UMTS modem can be accessed via ttyUSB0..2
• Install Gnome-PPP:
  • aptitude install gnome-ppp
• Now, you need to configure Gnome-PPP to access the internet via UMTS:
• Start Gnome-PPP via the menu (Applications / Internet / Gnome-PPP)
• The main window should appear. Most providers do not need any special username/password because the authentication is done via your GSM card:
  • Username: umts (does not matter)
  • Password: umts (does not matter)
  • Phone number: *99**1# (this is important)
• Press “Setup”
• Tab “Modem”:
  • Device: /dev/ttyUSB0
  • Type: USM Modem
  • Speed: 460800
  • Phone Line: Tone
  • Check “Wait for dialtone”
• Click on “Init Strings”:
  • Init 2: AT&F (Reset to defaults)
  • Init 3: AT+CSQ (Show link quality)
  • Init 4: AT+CGDCONT=1,”IP”,”internet.eplus.de”
    (this is the APN AccessPoint)
  • This APN (internet.eplus.de) is correct for
    BASE and Simyo. If you are using another provider, ask him about the correct APN.
  • Close the “Init Strings” window
• Tab “Networking”:
  • Check “Dynamic IP address”
  • Check “Automatic DNS”
• Tab “Options”:
  • Check “Minimize”
  • Check “Dock in notification area”
  • Check “Auto reconnect”
  • Select “Check carrier line”
  • Select “Check default route”
  • Check “Ignore terminal strings (stupid mode)”
• That’s it!
• Close the “Setup” window and click on “Connect”.

Congratulations, you should now have a working internal UMTS connection!

You can distinguish the two models by looking at P/N on the EeePC box or by opening the EeePC and identifying the SSD itself:

• The slow SSD model has this P/N: 90OA0BTI4214AFNE2X2Q, the SSD is labeled “P2-SSD PS Rev. 2.0G”
• The fast SSD model has this P/N: 90OA0BTI8214AFNE2X2Q, the SSD is labeled “S4-SSD JM Rev. 1.1″

I made sure that I got a fast SSD model, but the question arises:

How fast is it?

Today, I found the time to perform some benchmarks of the SSD read/write speed.

For your information, I’m using two partitions with ext3 filesystem.

One partition contains the Linux base system and the programs and is not encrypted. The other partition keeps my data (including my /home) and is encrypted using Linux’s LUKS infrastructure. I’m using AES 256 bit encryption (aes-cbc-essiv:sha256).

For the test, I created a 512MiB testfile using “dd”.
To avoid biased results because of Linux’s extensive file caching, I’ve rebooted the system after the write command, before doing the read speed test.

Unencrypted write test

che@eee:~$ dd if=/dev/zero of=/unencrypted/ssdtest bs=512k count=1k
1024+0 records in
1024+0 records out
536870912 Bytes (537 MB) copied, 22,7062 s, 23,6 MB/s

Unencrypted read test

eee:~$ dd if=/unencrypted/ssdtest of=/dev/null bs=512k
1024+0 records in
1024+0 records out
536870912 Bytes (537 MB) copied, 6,62449 s, 81,0 MB/s

Encrypted write test (aes-cbc-essiv:sha256)

eee:~$ dd if=/dev/zero of=/crypto/ssdtest bs=512k count=1k
1024+0 records in
1024+0 records out
536870912 Bytes (537 MB) copied, 31,3594 s, 17,1 MB/s

Encrypted read test (aes-cbc-essiv:sha256)

eee:~$ dd if=/crypto/ssdtest of=/dev/null bs=512k
1024+0 records in
1024+0 records out
536870912 Bytes (537 MB) copied, 28,2782 s, 19,0 MB/s

Of course, the performance on the encrypted partition is much slower than on the unencrypted partition. Furthermore, the CPU performs at 100% load when encrypting/decrypting, and that leads to a much shorter battery life. Therefore, I think it’s the best trade-off to only encrypt the data and keep the Linux base system unencrypted.

Conclusion

I’m very happy with the overall speed of my system, the slower performance of the encrypted “/home” is not really noticeable under real work conditions.

In this benchmark, there is of course a big difference between the unencrypted (W: 23.6MB/s, R: 81.0MB/s) and the encrypted (W: 17.1MB/s, R: 19.0MB/s) filesystem.

But remember: To have a secure system, it’s very important to move some directories to the encrypted partition, like:

• /home
• /tmp
• /var/tmp (I’ve moved the whole “/var” to the encrypted partition)

And depending on your system setup:

• /srv
• /var/spool
• /var/cache
• /root
• …everything else that you like to protect from thieves

Furthermore, it very important that you either also encrypt your swap partition or do not use a swap partition at all!

I’ve installed 2GB in the EeePC and do not use a swap. Of course, using a LUKS swap partition with a random key would also be secure.

• The EeePC is great!
• The screen is a little bit to dark
• The workmanship could be improved
• Conclusion

The EeePC is great!

It’s (for my purpose) the perfect travel companion with a good tradeoff between size/weight and performance. The battery runs for a long time (5-6 hours).

The screen is a little bit to dark

When using the EeePC outside on sunny days, the screen is a little hard to read because even with 100% brightness, it’s still pretty dark.

The workmanship could be improved

One thing that bothers me is the poor workmanship of the EeePC case. My EeePC is only one month old and I always transport it carefully in a suitable notebook bag. Nevertheless, the case already looks very “used”.

There are some kinds of “micro cracks” in all four corners of the lid cover. I think the glue between the (transparent) top of the lid cover and the (white) main part of the lid did loose a bit and that creates this “micro cracked look”.

Furthermore, the hotkey bar stained the inner side of the lid.

But these small quality problems do not really change my opinion about the EeePC. It’s just a recommendation what could be further improved…

Conclusion

Buying the Asus EeePC 901 Go was one of the best acquisitions in my life!

It’s size, weight, performance, battery life and connections (LAN/WLAN/UMTS) make it the best companion for people who need “real” access to internet (not some kind of semi-internet-access like e.g. an iPhone offers) while travelling around.

I love it!

So, I bought an Indian prepaid SIM card (I’ve choosen Airtel). That was the easy part. With this SIM card I can make calls to Germany for a few rupies (around 10 Rupies=0.15€ per minute).

But getting the GPRS internet access working was a bit more complicated. Airtel SIM cards do not have GPRS activated out-of-the-box.

I searched the web and found many different opinions, how to get this work. But, in fact, none of them worked for me. The guys at the airtel shop also told me something different, also the guys at the Airtel customer care hotline (call 121 to reach them, but be prepared that their English is – uhm – different).

Finally, I found a very easy solution solution. It works great for me is is pretty cheap. They will charge 0.3 Rupies per 50kB without any additional fees. So, one Megabyte will cost 6 Rupies or ~0.10€. That’s ok for me.

Here’s what you need to do to activate GPRS on your Airtel SIM card:

• Dial *567#
• You will receive a message with GPRS options (“1” to activate GPRS, “2” to deactivate)
• Answer to the message with “1” (without the quotes)
• You will receive a message with possible GPRS tariffs (for me, there was only one tariff available: “1” 0.3 Rupies for 50kB)
• Answer to the message with “1” (without the quotes)
• That’s it, you will receive a confirmation message and the GPRS settings for your phone in the next few minutes
• On the laptop, create a dialup connection that uses your mobile phone as modem (via cable, IrDA or Bluetooth) and use “*99***1#” (without the quotes) as phone number, and a any text as username and passwort

As you see, it’s really easy if you know what to do.

For your information, the GPRS access point (AP) for Airtel is “airtelgprs.com“, but normally, you don’t need it, because they will send you the settings for your cell phone by SMS.

PS: I can recommend Airtel for India, they have a good network coverage, even in rural areas, you can recharge your phone on every second corner and the tariffs are pretty cheap.
