German Scientists Successfully Test Brain-Controlled Flight Simulator

Angstroem EEG-based crap (73 comments)

Given the approach, the listed "successes" are no wonder.

This EEG-based stuff typically works on the so-called P300 response, i.e., the fact that 300ms after(!) thinking something you can measure a response in the brain waves, if you just look closely enough.

Unfortunately, that's not only horrible laggish, but also not really precise. For more complex tasks like easy games like train simulators you already end up having positive interpretation in the range of 48% to 52% (so closely centered around guessing ...), with most test subjects not exceeding around 60-65%.

With some few test persons you might be able to get something in the 70-90% range, but from what I've seen over time I have a feeling that they rather get trained (or somewhat train themselves) to produce responses the EEG pickup system can read better rather than the computer getting better at reading their brainwaves.

Using P300-based spellers achieves a best-case net bit rate of around 2 bits/second. So already typing a single character will take in the range of 3 seconds.

I don't see how this will ever be sped up unless we go for deep brain-probing, which probably no human test subject wants to volunteer for (it's used for mice experiments, though, in certain virtual reality experiments studying learning and orientation).

Come Try Out Slashdot's New Design (In Beta)

Angstroem Horrible. (1191 comments)

If that will become the new /. look, it will just be another site looking like any other half-assed wordpress site optimized for smartphone browsing. Seriously, why is everyone thinking that all sites should look alike? It's boring!

And, of course, you do know that there are still people using real PCs on screens bigger than 9"? Especially among the /. readers.

So make it at least two CSS style sheets, one for the mickey mouse screens and one for the real ones -- and let the users select.

Firefox 20 Will Finally Fix Private Browsing Mode

Angstroem Re:Weird bug introduced with FF17? (186 comments)

Why do I still get updates? Seems kind of weird to me to update unsupported versions ...

In any case: It's not even related to Ubuntu versioning (discussing the Ubuntu version was a moot point anyway, but some people like to rather jump on these rather than dealing with the problem).

As I found out meanwhile, it's a problem of the Trinity desktop environment regarding mapping GTK widgets to QT widgets, potentially affecting every user of that desktop environment, no matter what recent or not-so-recent Linux distribution they are using ... Removing the kgtk-kde3 package solves the issue.

Firefox 20 Will Finally Fix Private Browsing Mode

Angstroem Re:Weird bug introduced with FF17? (186 comments)

Anything helpful to say?

It still is supported, btw, Desktop until 04/2013, Server even until 05/2015. So much for that. (You do know what LTS stands for, right?)

Besides, behavior like this

  • FF will not crash, when strace'd.
  • FF will also not crash, when started via "ssh localhost".

does not sound like some "get your .mozilla directory fixed" kind of problem (which doesn't help btw.), but some race or whatever mess going on.

Firefox 20 Will Finally Fix Private Browsing Mode

Angstroem Weird bug introduced with FF17? (186 comments)

After upgrading to FF17, the browser started crashing whenever the file dialog pops up for up- or downloads. It doesn't matter whether the file is double-clicked or selected via "Ok" -- the browser instantly crashes afterwards, sending home a crash report.

That very behavior also takes place with FF18. When running the with strace, the crash does not happen. FF16, in term, does not show this bug.

Any idea how to hunt this down or even fix it? (I'm running Ubuntu 10.04LTS w/ Trinity/KDE3.5)

Newly Developed RNA-Based Vaccine Could Offer Lifelong Protection From the Flu

Angstroem Re:DO NOT WANT.... (156 comments)

In Finland (and possibly the other Nordic countries whose welfare states served as a model for Finland's) you don't get a sick day unless you visit your neighbourhood's clinic in the morning and get a doctor to sign off on the sick day. On the plus side, you get paid for the day.

I don't know about you, but if *I* am sick, I'm in no way able to visit the nearest doctor's office (and definitely no clinic), especially not in the morning, because I'm fever-struck or similarly immobilized. Just feeling "meh" does not equal being ill.

Luckily, I'm living in Germany where employers usually demand the sign-off only from the third consecutive day on -- unless people show an obvious tendency for being sick at Fridays, Mondays, bridging days, or denied vacation days; but who abuses a system of mutual trust is asking for such measures.

And yes, we have (almost) unlimited paid-for sick days in Germany, of which the first consecutive 42 typically come out of your employer's pockets. Yet, the overall abuse rate is comparatively low.

3dfx Voodoo Graphic Card Emulation Coming To DOSBox

Angstroem Re:"Historical" (156 comments)

Get off me lawn, you youngsters!

When I was young we carefully wove ALUs using 74xx and 40xx, and we saved our programs to paper tape!

Sheesh, I remember, when "high-resolution graphics" meant 256*192 pixels. Not necessarily colorized ones, so forgive me shedding tears when I look at old Amiga ads remembering the stunning first sights of the 4096-color Hold-and-Modify mode...

KDE SC 4.7 May Use OpenGL 3 For Compositing

Angstroem Re:Have you reported this as a bug? (187 comments)

Unfortunately, very few developers actually test their stuff with ~ on NFS. Firefox is another program which fails hideously with ~ on NFS -- the bookmark toolbar would fail to load, misc. random errors upon loading pages, etc. (I think it was because of Sqlite, but I'm not sure.).

Ah, the joys of Firefox on networked file systems.

I happen to have my work home on AFS, which has an "official" path /afs/[much longer path here]/home/angstroem -- and the localized official path /home/angstroem

Now guess, which path Firefox uses in its config files, just to fail on that at later restart. After forcing all paths in its config files to /home/mylogin anything is fine and even restart works.

Killer Apartment Vs. Persistent Microwave Exposure?

Fingerprint Requirement For a Work-Study Job?

Angstroem Re:Oh no! (578 comments)

With all due respect, you are a dumbass.

Here's one guy who still uses his brain for thinking, and he just doesn't see what this fingerprinting (which you may have forgotten was used as a special treatment for criminals in former times) is all about.

If they want to check his presence, logging him in and out, there are other methods to do that. They don't need his fingerprints. It worked perfectly well with badges and/or company ID cards.

And, yes, his fingerprints are all over the doorprint. Together with a gazillion of other fingerprints. And withoug registration that makes him one of the anonymous crowd.

Before all this "we need your fingerprints for this and that" nonsense, of course, as his fingerprints weren't not registered.

Now they are.

It's easy to ridicule people as paranoid. Instead, however, you should be thinking "why the heck are they requiring my fingerprints".

Spyware Prank Exposes Hospital Medical Records

Angstroem Re:The Woman (319 comments)

That customer is lost anyway as you can't treat her right, no matter what you do...

But to come back to technical issues, your example is flawed, because

  • You don't need unlimited internet access for sending/receiving eMail.
  • Private network access is not required at work, therefore you don't even need access to any freemailers.
  • There's the concept of intranet. You don't need to intermingle intra- and internet. Set up two networks with very, very, very strict passing rules, if, for whatever reason, you need to access them from each other.

First Algae Car Attempts To Cross the US On 25 Gallons of Fuel

Angstroem Re:What do they mean? (188 comments)

A regular 25 gallons of diesel would get you to about 750 miles?

Excuse me? That's 95l of Diesel for about 1200km.

Even my 11 year old VW Golf IV TDI (1.9l engine w/ 90 metric HP/66kW) does 950km (590 miles) on *half* of those 95l/25gal and on a real everyday commuting mix, not some fake test course.

And I'm not quite known for my defensive driving, so I like to go fast wherever and whenever possible. The same car and engine can be driven 1200km (750 miles) on a single tank of 55l (14.5gal) if driven fuel-optimized rather than fun-optimized.

EMI Only Selling CDs To Mega-Chains From Now On

Angstroem Re:CDs? (334 comments)

A CD is a data carrier on which the audio data is typically stored in way less corrupted way than the Generation MP3 is used to consume.

Maybe my ears differ just enough from the average physical model, but listening to MP3 for longer time makes me dizzy -- and I see no point in buying artificially crippled audio.
