Bye Bye Spam

I just installed Hash Cash, which is an anti spam plugin for WordPress.

Hash Cash protects this blog from spam by requiring the client to execute javascript which calculates a checksum of the content from a seed which is very hard to extract.

Since I installed it I haven’t got any spam comments :-).

The downside is that it disallows anyone who hasn’t got a javascript enabled browser to post a comment.

Now I still need to get some good means to combat trackback spam. Just putting them under moderation isn’t good enough for they keep coming

XBox 360

Microsoft released the specifications of the XBox 360..
it is a beast..

With 3 CPU cores running on 3.2Ghz each with 2 hardware threads and 1 mb l2-cache each it is a powerhouse.

A remarkable feature of the XBox 360 is that it has got processor level support for MSIL (the bytecode used by .net applications).

The best thing of the XBox 360 is that it’ll be quite cheap (~150$), this probably lets the XBox360 deliver the most processor capability per dollar.

Maybe I’ll buy a few and make my own little linux server cluster with it, when the guys behind xbox-linux.org have added support for the XBox360 :-).

Music Fill Out Thingy

Zef handed me the music baton, meaning I got to fill out a form ’bout music. So well… here it is:

Total volume of music files on my computer
3.2 GB.. that isn’t a lot.. but in contrary to some with huge collections I do listen to them all.

The last CD I bought was
I got myself some albums of Children of Bodom recently. I`m trying to get the Lamentations DVD of Opeth.

Song playing right now
Opeth – Still Life – The Moor

Five songs I listen to a lot/mean a lot to me
I don’t really listen to a certain song a lot.. although recently I listened to these a bit more than the others:

– Opeth – The Drapery Falls
– Children of Bodom – Needled 24/7
– Nirvana – You Know You’re Right
– Opeth – Dirge for November
– Muse – Citizen Erased

Lets be creative and add another question:

Artists you like
Opeth, Children of Bodom, Nightwish, Nirvana, Linkin Park and last but not least Muse.

The five people where this meme will go on
Kaja Fumei
– Noud Aldenhoven
Gumuz
– you!
– (yes, i was out of idea`s)

Copy protecting

From software, audio to video are being illegaly copied and everytime the major brands try to implement some kind of protection. They always claim their protection to be perfect, and yet it is always broken, for it is quite simple:

As long as the intended user has the platform on which he`ll run it in his own possession he can always adapt it in someway to extract the data. Even the best video protection can’t beat making a bypass in your monitor to acquire the image on your screen.

Even protecting something like a DVD is almost impossible. The dvd player hardware and software must be able to read what’s on the cd, and a protection must be able to be read to. Also there must be dvd writers to write a protection. Now all major brands can say they’ll put a protection in their DVD burners to protect from writing to the DVD protection section, but then another brand creates their DVD burners that can write to it and everyone will buy those which the big brands won’t let happen. And even if they got the disk itself truly protected someone can emulate the DVD using software or even hardware.

Also there are things that allow itself to be copied, but the original copier can be tracked; this by putting in every video/song/software a unique signature which can be tracked back to the store which then can track it back to the person who copied it. Sounds great, would be impossible to forge when they use strong RSA like cryptography, just one problem, when inserting random trash instead of the signature someone can know the piece is illegal but cannot track someone, hopeless.

The only, and only way, to stop illegal copying is making buying legaly less of an effort than acquiring illegaly. I hope they will relize this sooner or later for honoustly I`m becoming sick of all those ‘magic’ protections.

Strange spam

The last few days this blog has been under heavy attack of comment spam. Although the excellent wordpress filters have put all of it in the moderation queue it still is quite some work so sift out any comments that actually are of a real person.

The odd thing I noticed out of curiousity is that the links don’t even seem to work on more than half of all the spam comments. They are basicly flooding you with for them hopefully tempting comments and if someone finaly has been tempted enough to click one it doesn’t work!

Microsoft Anti Spyware

Microsoft Anti Spyware beta

It looks to work well, it even detects some adware that adaware didn’t remove.

It is said by many people that using more than one anti-adware program is the best way for they all don’t catch everything. Joel suggests why Microsoft Anti Spyware wouldn’t catch everything: conflicts of interest.

A lot of money is made by redistributing spyware/adaware/malware on people’s computers. They could easily bribe some anti-adware software developers to ignore their adware.

I just got to find an anti-adware program that is proffesional enough to clean my computer, and isn’t bribed to leave some.

The problem is that there are a lot of anti-adware programs, most of them are adware themselves.

Blog updated

The blog has been updated to 1.5.

It adds a lot of nice new features and I would like to advice other users to upgrade now.

The new skin is the new default skin that comes with WP1.5.

When I find time I’ll adapt it a bit to make it a bit less default.

Edit Just noticed that the wordpress ACP looks horribly scrambled in Firefox, looks all right in internet explorer though :(.

Gamma Wave Effect

As promised a few pictures of the electric guitar effects we’re working on,

first up, the gamma wave effect.

The gamma wave effect pulls the amplitudo’s either to the 0 line or the -1/1 line, just like the gamma on your monitor does:

Max Negative Linear Gamma Applied

Max Positive Sine Gamma Effect

The effect basicly makes the wave a lot louder and gets rid of the faint sounds. When on fully applied as in the images above it also creates some distortions due to either making the wave unharmonic-ish or getting rid of the nuances.

Another image taken on a higher oscilation (smaller zoom):

Max Pos Sine Gamma 2

This clearly shows the distortion

(The inversion of peak and valley doesn’t matter for for sound only the transition from a valley to a peak matters)
