In 2006 Thiago Olson joined the extremely sparse ranks of amateurs worldwide who have achieved nuclear fusion with a home apparatus. In other words, he built the business end of a hydrogen bomb in his basement. The plasma "star in a jar"—shown at the left—demonstrated his success.

For two years, Olson researched what he would need and scrounged for parts from eBay and the hardware store. Flanges and piping? Check. High-voltage X-ray transformer? Check. Pumps, deuterium source, neutron bubble dosimeter? Check, check, check. “I have cross-country and track, so during those seasons I don’t have much time to work on it,

Tokyo, Japan, Mar 23, 2007 - (JCN Newswire) - Sony Corporation today announced "CLEFIA",[1] a new highly secure and efficient block cipher algorithm that delivers advanced copyright protection and authentication, which is essential in the growing environment of digital data distribution, such as music and images. Based on cutting edge cipher design techniques, Sony's "CLEFIA" block cipher maintains high security levels while providing both world-leading hardware and software implementation capabilities, the combination of which had proved difficult until now. Sony will unveil the results of this development at the "Fast Software Encryption 2007"[2] international conference, to be held in Luxembourg for three days from March 26.

Sony's newly developed "Diffusion Switching Mechanism (DSM)"[3] technology is the result of research into improving security while reducing overall cost. It successfully achieves secure cipher algorithms, even with fewer operations, by selecting the optimum diffusion matrices in the Feistel structure[4]. This technology enables reductions in gate size when implemented in hardware, and greater implementation efficiency when used in software.

The key advantages of "CLEFIA" are its enhanced implementation efficiency in terms of both hardware and software, and its high speed operation. When implemented in hardware it achieves maximum throughput of 1.42 Gbps using a 0.09 micrometer CMOS standard cell library and gate size of just 6.1K, representing the world's highest hardware gate efficiency. Consequently, "CLEFIA" is able to provide advanced capabilities, even in restrictive environments such as smart cards and mobile devices. When implemented in software it can realize high speed performance on a wide variety of processors.

The "CLEFIA" interface corresponds to 128-bit block cipher technology such as the US government's Advanced Encryption Standard (AES), and the ISO/IEC 18033-3 International Standards. Block length is 128 bits, while key length can be selected from 128 bits, 192 bits, and 256 bits.

The "CLEFIA" cipher is meticulously designed to concentrate state-of-the-art cryptanalysis techniques and achieve sufficient immunity against known cryptanalytic attacks. Sony has cooperated with Japan's leading researcher in this field to create this design, and has had the new cipher design verified by a number of third party experts overseas.

Going forward, Sony will seek to establish an environment in which "CLEFIA" can be used across various applications and products such as AV devices, while continuing to develop technologies that our customers can use with confidence.

I wonder how this will fare against AES.  Considering Sony's market, this may actually get some "swing".

Madruscoe (aka moneytoo; the maker of PMP Mod AVC) has informed us about this bit of homebrew news. PMPlayer AdVanCe (PPA) by cooleyes (cooleyes_lf) has been updated. The homebrew application plays PMP files with AAC support. It also has skins, standby, TrueType (TT) fonts, and more features. More importantly, it has an English skin (although you have to do a little tweak to get it):

    
• To have an English skin for PPA, edit the config.xml by changing MHP to normal-en (you change the part that says "MHP" into "normal-en").
  
  The release notes are in Chinese. For those who are curious, you can try to read the nasty Google translation, but if anyone can read Chinese and translate it for us, though, that would be great too, and wee will be forever grateful.
  
      
• [Core] broadcast :
            o AVC Mod 1.02M improving on the day, that some original BUG
            o support multicast, Chain function. The broadcast counterparts installed window mode (single individual broadcast multicast group, all-running)
            o Support channel switching functions around the "br everywhere -- AAC support (limited sampling rate of 44.1KHz)
            o Support the designated interface, the interface can be manually waiting in the main, if not more than five minutes to operate, you will be automatically entered; presented does not support the staging, please do not try to, it may lead to erroneous or even Deadlock
      
• [Interface & Skin : --
            o pretty File Browser interface, with the help of perfect information (hereinafter referred to the original skin CG illustrated AreX producer) rich installed option "br everywhere -- arbitrary list of open broadcast Wi-Fi support USB & PMPAVC films broadcast on the PC. directly delete film.

JUST FOUND IT!!
It's in vshmain.prx:
On my decrypted 3.00 PRX (should be the same for all), go to 0x353E0 and you'll see a whole bunch of floats - I'm not too sure how it works, but it's stored there.
The "-130" value (default left position of XMB) is 0xC3020000 in hex, so you'll see a few instances of that.  Replacing that will fix the "return bug" :D

Hmm, vshmain.prx does indeed contain some very interesting things...

How's this for nice?

The BBC is reporting that everyone who purchased a PS3 at the London launch of the console received a free 46-inch HD television and a taxi ride home.

Holy!

That's About GBP 250,000 worth of televisions and cab rides to more than 100 gamers. The guy at the front of the line waited a whopping 36 hours.

So let me get this straight. Wait two days in the U.S. for a PS3 and you get a gut full of shot. Wait two days in the UK for a PS3 and you get a free cab ride and television.

OK, no more whining about how you guys had to wait longer.

Tricky Nokia. Thought they could get away with their secret N99 slider that not only houses a QWERTY keyboard, but also a widescreen display and an 8-megapixel camera. Well, the folks at Unwired View dug up this patent that jibes with earlier rumors. It even shows the addition of a twisty number pad. Looking good, all wee need now are some more "leaked" shots.

Quote:Want to spruce up your PSP even further? Well, LiammR and Palmer have created another modification you can flash onto your PSPs, known as the USB Sliding Bar Software Mod.  

As the name implies, the USB Sliding Bar Software Mod alters the look of the sliding bar on your PSP's USB mode when transferring files. You can make it black, turn it into an arrow, a shooting memory stick, or even the words "USB" just by doing the proper alterations to your PSP's flash.

As always though, messing with the flash also means you're going to mess with the gods of fate, as you may just brick your PSP, despite all the care you put into reducing the risks. If you know how to find ways to unbrick your PSP though, or simply have the guts to try, then you're definitely welcome to try this application out. In the meantime, below is a video of the app in action. Enjoy!
