Most tech geeks may hear about Maemo system in the past several months.Well,it’s finally on the table now and will be introduced by Nokia.

Nokia is going to show off its latest mobile device-N900 and it will be packed with Maemo5 operating system instead of Symbian.

  • 1G RAM
  • 3.5 inch 800*480 touch screen
  • Slide QWERT keypad
  • 32GB internal memory and expandable up to 48GB of MicroSD card
  • GPS/A-GPS positioning
  • FM radio
  • Bluetooth 2.1 and WIFI
  • 5.0 mega pixel Carl Zeiss Len with LED flash
  • 1320MAh battery
  • OpenGL ES 2.0 display accelerator
  • GSM/EDGE, 900/1700/2100MHz UMTS/HSPA

After all,I just feel that Laptop has gone into autumn and this sort of devices is just opening for a new age.Well,the price is still quite high-around US$700.If you like it,let’s have a deep look then.

I bet you like it.Me too! :D

Linksys WRT54GL V1.1

I bought Linksys WRT54GL years ago which previously worked with an Aztech modem.After the modem broke,the router was put into a corner as I had Linksys WAG200G modem router,acting well on normal use.

However,recently I’m heavy downloading and it makes the transmission congested once several PCs are using at the same time.I think putting the router into the network should be a good solution as I could do some QoS(Quality of Service) settings there so that optimize the entire network.

This router packs with Broadcom BCM5325 200MHZ CPU,16MB RAM and 4MB flash and it is set on Linux-based,so lots of third-party firmware which may boost the performance are available,such as DD-WRT,Tomato,Open-WRT etc.The official ‘stock’ firmware just means stable for normal use.For me,a DD-WRT or Tomato firmware would only fit my needs.

Steps to install DD-WRT firmware:

  1. Turn the router into default settings(stock firmware)
  2. Upgrade to DD-WRT mini firmware and reset
  3. Upgrade to DD-WRT standard/VPN/VOIP firmware and reset
  4. Configuration

After I flashed the new firmware,I started P2P downloading as a test.I used QoS setting allowing 60% of bandwidth for P2P downloading and 40% for HTTP and others.I’m not quite satisfied with the result because it still made the network congested;in addition,the interface loads very slow.Thus,I decided to try Tomato firmware immediately.

Steps to install Tomato firmware(directly from DD-WRT V24SP1):

  1. Turn the router into default settings(of DD-WRT)
  2. Upgrade to Tomato firmware and reset
  3. Configuration

It’s a very simple trilogy.The interface is very clean so that setup will never be a tough thing.Ajax technology makes the interface load very fast and consistent.What is important is that no more congestions while heavy loading.Awesome!

From now on,I will be able to fully utilised the bandwidth of DSL broadband without annoying.Happy day! :D

Took a lesson again

Yesterday I read a lot of articles about IT and I found that Ubuntu is more and more popular nowadays.

Since my interest on it was coming,I got a try to install ‘dual system’ in my PC-Windows XP+Ubuntu 7.04.I had referred tons of articles of the common issues before I started to install it.

It gave me a shock first when I redivided drivers-some unallocated spaces can not be used to form a new partition.I tried my best to figure out the problem without creating issues,but the fact was the worse.I did wrongly procedures so that I deleted one of my existing driver.My god,my pictures and documents are stored there.That was a big loss to me.

But I did the half way so I have to continue my work.Luckily,the following procedures were likely to be smooth and with around 30 mins auto-installation,the whole setup had been completed.I just waited it restarting and wish to see the ‘welcome windows’,but that made me sad again.Some errors were occured which led to fail in restarting and even can’t choose OS.

Damn it.After this grief ,I have to face the facts.So today morning,I reinstall windows and those necessary components again.From the things,I know that backup is very important and Ubuntu is not so easy to use for me till now.On the other hand,it’s jeering on my lacking skills.Perhaps I need to take more time to learn more about it and then start my hands to do it.
