UEFI Secure Boot Pre-Bootloader Rewritten To Boot All Linux Versions

ProfMobius Re:Isn't this, "also Linux works round Samsung bug (185 comments)

Agreed. From http://www.jakobheinemann.de/en/blog.html :

The implementation in Samsungs UEFI shows some weird behavior. Error code EFI_INVALID_PARAMETER should only be returned, if one of the given pointers to variables is NULL and pointing to an invalid memory section. Samsungs implementation also throughs this error, if the given memory blocksize is not exactly 128 bytes, so for example (like the Linux-efivars module does) 1024 bytes. The Linux module does not expect the strange error code (it checks for NULL pointers itself) and does not report any UEFI variables, no boot entries, no nothing. The installer accepts that and installs the Linux boot entry into the first slot, where actually the boot entry for the setup is located - overwriting that entry! Setup is dead since Linux took its boot entry.

It does look like the Samsung implementation is doing weird things and Linux is doing weird things in return because it is expecting it to follow standards...

New Sony PSN ToS: Class Action Waiver Included

ProfMobius Re:South Park "CentiPad" anyone? (378 comments)

You did a great job at talking about everything NOT relevant in the episode, beside the relevant part (and the central one). Namely, putting weird clauses in EULA that people do not read but remove some of their basic rights.

Data Review Brings Major Setback In Higgs Boson Hunt

ProfMobius Re:poorly worded (180 comments)

Thank you very much. I was waiting for someone to realise that this article has nothing to do with the Higgs boson. It is about one experiment finding a new particle, and another one finding nothing. It is NOT about the Higgs.

Data Review Brings Major Setback In Higgs Boson Hunt

ProfMobius Re:Please explain to this non-physics-type geek (180 comments)

They discovered monopoles ? Do you have any reference for that, because I'm pretty sure it would give the finder a direct nobel price.

The Machines That Sparked the Beginning of the Computer Age

ProfMobius Re:Good bye and thanks for all troll food... (139 comments)

Not sure what you are trying to achieve here. And your title should have been "Good bye and thanks for all the trolls", at least it would have made sense...

The Machines That Sparked the Beginning of the Computer Age

ProfMobius Enigma emulator on linux (139 comments)

Speaking of Enigma (or SIGABA from a previous post), does someone knows any good emulator/decoder for Enigma on linux ? I found this http://users.telenet.be/d.rijmenants/en/enigmasim.htm but it is a bit too visual for me (you have to drag and drop the rotors yourself, etc), it doesn't decode and it is for windows.

I'm more interrested in an open source command line tool, with decoding abilities.

Upscaling Retro 8-Bit Pixel Art To Vector Graphics

ProfMobius Re:Wonderful! (325 comments)

That's an interresting suggestion. I didn't think about it. By using a video instead of a fixed picture, you can extract more information out of it. I suspect you will never reach a 'super zoom' feature using this, but by linking pixels between frames and comparing the shadow between them, etc, it should be possible to reconstruct a low resolution volumetric representation of the original object.
Interresting work indeed.

Upscaling Retro 8-Bit Pixel Art To Vector Graphics

ProfMobius Re:ZSNES (325 comments)

1. Apply it to each individual sprite while loading the ROM.
2. Create an alternate sprite table with vector graphics.
3. Create two rendering loops, one internal for the original sprites and one going to the screen with the new sprites.
4. ???
5. Profit

Most of those filters have been around for quite some time. I remember using ZSnes with the SuperEagle filter in the begining of 2000s.

Upscaling Retro 8-Bit Pixel Art To Vector Graphics

ProfMobius Re:Wonderful! (325 comments)

Examples of this kind of work are found in practical applications such as number plate recognition, where often a bad photograph is the starting point. This allows elements to be reconstructed even when information is partially missing.

This kind of enhancement is only possible because some assumptions are made on the original content. This is equivalent to this enhancement tool which can recreate the text bellow a blurred image. The assumption is that you only have around 36 chars under the blur (or pixelization). In this case, the kind of information you are trying to retrieve is clearly defined and quite reduced.

This is obviously not true for other kind of applications, like faces, sprites and such. There is no way to reduce the information space to a practical size in order to constraint any algorithm. In those case, what you are doing is CREATING information, not RECOVERING information.

Upscaling Retro 8-Bit Pixel Art To Vector Graphics

ProfMobius Re:Wonderful! (325 comments)

Because the information is simply not there ? You can add as much information you want to your pixels like curves and such, but you have no way to prove it is the original information.

From TFA : "The other problem is that the Depixelizing Pixel Art approach always smooths images, even when an object shouldn't necessarily be smooth. For example, are Space Invaders really meant to be cute and round? Maybe, in the creator's eye, they had long, angular, razor-sharp mandibles and straight-out antennae! "

They are adding information, but they have no way to know if it is what the original artist had in mind.

Sony Sued For PlayStation Network Data Breach

ProfMobius Re:Are the grounds for this lawsuit even valid? (404 comments)

For what I gathered so far (I don't own a PS3), PSN is free, buying on it is not. The credit card is not required to register to PSN but only if you buy games on it.

You are the one without a clue, go play somewhere else.

Indie studios propose the Humble Bundle

ProfMobius ProfMobius writes  |  more than 4 years ago

ProfMobius (1313701) writes "Ars Technica has an article on a promotion from a group of indie game studios.

A group of indie developers are selling a package of their games which includes some of the biggest independent games on the market. Gamers can name their own price from 1 to $1,000 for a pack of games that would go for around $80 if sold separately. Anyone who buys the package can feel better about themselves as well; customers can send any amount of their purchases to two major nonprofit groups.

The games are World of Goo, Gish, Lugaru, Aquaria, and Penumbra Overture. The two organisations are the EFF and Child's play. On the website of the offer, it is possible to chose how to split the cake to each group (between the devs, the EFF and Child's play)."
