A new infrared 3500DPI sensor forms the core of an updated Razer Deathadder and an updated Razer Salmosa, the Razer Abyssus. Their predecessors were good mice, with some small issues.

The original Deathadder is Razer’s best mouse in my opinion. It has a great sensor which tracks very well on a lot of surfaces, is capable of tracking at high speeds, has DC and NDC firmwares and has no acceleration or other side effects when set up right.

The Salmosa has received little love from Razer. 1 driver update, no firmware updates and only the default DC firmware available.

Salmosa

So let’s talk a bit first about the thing the new mice have in common, the 3500DPI sensor. It’s not as good as the trusty old 1800DPI sensor used in the Salmosa and Deathadder-new. It has a lot of issues tracking on cloth mousepads, some more than others. Ironically, it’s pretty bad on the Razer Goliathus.  If you like to play on cloth pads, don’t buy an Abyssus or a Deathadder-new.

Deathadder-new

With that out of the way, a bit about the Deathadder-new. It’s pretty much exactly the same as the old one. It has a nicer braided cable, replacing the very thin plastic wire from the old one, which was prone to breaking internally. That’s basically all there is to this new Deathadder. If you have an old one, keep it, if you want a new one, try to find an old one. The changes are not worth the upgrade and extra costs.

Deathadder new, or old?

Abyssus

Compared to the old Salmosa there isn’t much new either, but at least the 3500DPI sensor doesn’t have drift control. The hardware buttons to switch DPI and mouse refresh rate are still there, but the 500Hz option is gone. The scroll wheel is the worst I’ve seen on a Razer mouse. It feels cheap, makes a weird noise and is definitely not as good as the Deathadder or Imperator scroll wheel. Just as with other Razer mice there are a lot of reports of squeaking mouse wheels on the Abyssus.

Abyssus

For some reason I still like the Razer Abyssus. It’s really light and small, easy to throw around. Great for people looking for a finger grip mouse. The buttons are easy to press, I’d rankthem like this (easy -> hard to press): Boomslang CE2007, Abyssus, Deathadder, Imperator

Remotely upgrading a kernel without some sort of remote KVM solution is not for the faint hearted. Realizing you forgot to include some module, or build the initrd image after remotely rebooting a kernel is even worse

Luckily there are some nice tricks you can use to make a remote kernel upgrade as safe as possible.

First, make sure you have a valid kernel. Copy the .config of an old kernel and ‘make oldconfig’ to make it work on your new-to-be-compiled kernel.

Second, make the kernel using the ‘make-kpkg’ package, don’t forget the –initrd parameter if you need it.

Third, after installing the kernel package, don’t forget to check if the initrd image got generated. For some strange reason Debian won’t generate this even after building with make-kpkg –image, you can read more about that here. You basically need to copy a file from ‘/usr/share/kernel-package/examples/etc/kernel/postinst.d/initramfs’ to ‘/etc/kernel/postinst.d/initramfs’

Fourth, you need to configure Grub2 so it uses a kernel boot option which makes the kernel restart if it can’t boot for some reason. To do this with Grub2, open /etc/default/grub and add “panic=5″ to GRUB_CMDLINE_LINUX_DEFAULT, like this:

GRUB_CMDLINE_LINUX_DEFAULT=”quiet panic=5″

Fifth, Grub2 needs to be told to only boot the new kernel once, so in case the new kernel panics, it automatically restarts using a kernel you know works (your current one perhaps). Else the ‘panic=5′ we set earlier will only lead to a reboot loop.

To do this open /etc/default/grub and change GRUB_DEFAULT to saved, like this:

GRUB_DEFAULT=saved

To configure ‘reboot-once-into-new-kernel’, we need to do two more things, first we need to tell Grub2 what your working, safe kernel is. Check /boot/grub/grub.cfg for the name of this kernel, but don’t change anything in this file.

My safe kernel is called: ”Debian GNU/Linux, with Linux 2.6.32-2-686″, which I can set as the default, safe, kernel with this command:

grub-set-default ”Debian GNU/Linux, with Linux 2.6.32-2-686″

Now we have to tell Grub to reboot once into the new kernel, again we need the name of the new kernel, mine is ”Debian GNU/Linux, with Linux 2.6.32-example”, use this command.

grub-reboot ”Debian GNU/Linux, with Linux 2.6.32-example”

Don’t worry, this won’t reboot your machine.

The final step is to generate a new /boot/grub/grub.cfg, else all the things we just did won’t have an effect

update-grub

Now you’re ready to reboot, good luck and fingers crossed. After a succesful boot, you can set your new kernel as the default using the grub-set-default command

grub-set-default ”Debian GNU/Linux, with Linux 2.6.32-example”

Razer’s past 5 years have been quite succesful. Clearly becoming a leading gamer’s brand that pushes the envelope. The hugely succesful Diamondback, using a temporarily Razer-exclusive sensor, showed Razer was back in business after their crappy first optical mouse, the Viper.

Following the Diamondback was an OK laser mouse, the Copperhead, and the awesome Deathadder, Razer’s first right-handed mouse. It was a great upgrade for gamers looking for the next best thing. The very good Avago 3688 sensor, with 1800DPI and very high maximum speed, guaranteed excellent tracking and is still one of the best sensors available. The familiar ergonomic shape pleased many coming from Logitech’s aging MX5xx line and Microsoft Intellimouse series.

The Deathadder was released over 2 years ago and is still very popular. Recently a newer 3500DPI version was released, which I’ll be reviewing soon as well. (Early verdict: Not as good as the old one.)

Imperator

This review, however, is about the Razer Imperator.

A week ago I got a new phone, the HTC Hero.

It’s an Android based phone so it’s easy to customize and there are a lot of great apps available for it.

However, HTC’s default firmware is a bit sluggish. Luckily there’s a solution. It takes 5 minutes and besides speeding it up, it also ‘roots’ it. ‘Rooting’ an Android phone allows a user to do basically anything he wants with the phone.

Here are the steps (by Paul of MoDaCo)

- Download the custom ROM, and copy it to your SD card (modaco 2.2 core)
- download this file (http://content.modaco.net…copatchedrecovery-1.0.zip) and extract it to your PC or mac
- open a command prompt to the directory containing the extracted files
- type the following commands (prefix each command with ./ if you’re on a mac)
- adb shell reboot bootloader (wait for device to reboot into bootloader)
- fastboot boot cm-hero-recovery.img
- Select ‘nandroid backup’ from the menu to do a backup
- If you copied the custom rom as update.zip, select ‘apply sdcard:update.zip’, else select the option below.
- all done

I’ve been struggling for quite some time trying to get 1080p content to play smoothly on my MythTV pc. I managed to get good playback of 720p files by compiling mplayer myself and using a recent version of the closed source nvidia driver.

Playing back 1080p content however, was still a problem. I was never able to get smooth playback with mplayer. Only the xbmc videoplayer could play 1080p smoothly on my system. XBMC is not an option due to the WAF, it has to be something that runs from MythTV.

Fooling around with coreavc-for-linux (I love CoreAVC on Windows) got me nowhere. Recompiling, tweaking and updating mplayer/nvidia/xorg, nothing seemed to work.

Until I tried a new version of mplayer from the Debian Multimedia repositories. The mplayer version in that repository has support for a new feature in the linux nvidia drivers that (finally) allows video decoding on the GPU.

The easy steps to get this to work:

• Download and install the new nvidia linux drivers (180+)
• Add the Debian Multimedia repository to your sources.list
• Install mplayer from the new Debian Multimedia repository
• Start mplayer with ‘-vo vdpau -vc ffh264vdpau’

More than a year of tweaking and tinkering made redundant by these easy steps, excellent!

It’s funny, because it’s true :/
