A Fictional Compression Metric Moves Into the Real World

retchdog Re:Trivial observation (133 comments)

yes, the metric is obviously a different thing, but they were both designed for the show.

a few mediocre professors are thinking of using the metric in their courses, but are pretty open about it mostly being a gimmick.

in conclusion, shove it up your bloated ass.

A Fictional Compression Metric Moves Into the Real World

retchdog Re:Trivial observation (133 comments)

It was designed as a background prop for a TV show. Not a very high bar.

It might be adequate as an artificial evaluation metric for homework in an "Intro to Data Compression" class. It might be, because it hasn't even been used for that yet.

I wouldn't exactly call this a tool. For example, it would be really easy to game this 'score' if there were any significant incentive for doing so. That's usually a bad thing.

A Fictional Compression Metric Moves Into the Real World

retchdog Re:Useless without measure of lossiness/distortion (133 comments)

it's for lossless compression only.

anyway, you can just add a term representing the lost information and throw it into this "score". hey, why not? just figure out how important the lossiness is relative to compression rate. if it's very important, take the exp() of the loss metric; if it's unimportant (like time is), take the log(); finally, if it's just kind of important, leave it linear, or maybe square or square root. whatever.

seriously, just make some shit up and throw it in. you won't compromise anything. it's already just made-up shit.

A Fictional Compression Metric Moves Into the Real World

retchdog freemasons run the country (133 comments)

The so-called Weissman score is just proportional to (compression ratio)/log(time to compress).

I guess the idea is that twice as much compression is always twice as good, while increases in time become less significant if you're already taking a long time. For example, taking a day to compress is much worse than taking an hour, but taking 24 days to compress is only somewhat worse than taking one day since you're talking offline/parallel processing anyway.

The log() seems kind of an arbitrary choice, but whatever. It's no better or worse than any other made-up metric, as long as you're not taking it too seriously.

For Half, Degrees In Computing, Math, Or Stats Lead To Other Jobs

retchdog Re:Incomplete data (174 comments)

put away your 'clever' strawman and grow up. mathematicians do, in fact, think of all of these things. i know several mathematicians working in statistical mechanics as well as others doing binary static analysis. rigorous, formalized thinking helps with almost everything. the halting theorem is an old, essential result; no one believes that it's the final word on what's (im)possible.

Man Booted From Southwest Flight and Threatened With Arrest After Critical Tweet

And before any of you complain, since surgery I can walk fine.

Did you just apologize to a bunch of whiny pricks for being crippled?! What the fuck, man?

I'm glad you got surgery. Thanks for the account of your experiences.

For Half, Degrees In Computing, Math, Or Stats Lead To Other Jobs

retchdog Re:Incomplete data (174 comments)

hogwash. a lot of modern topics in CS are basically statistics: natural language processing; computer vision; most of machine learning; data mining; most of bioinformatics; etc.

statistics just has terrible marketing (at least in the US) and they've been a bit too focused on silly things, so they ceded a lot of ground to CS for no really good reason.

as for the other topics, if you follow the links you'll eventually come to the definitions. the article itself is terrible.

For Half, Degrees In Computing, Math, Or Stats Lead To Other Jobs

retchdog Re:Four year engineering degrees- great (174 comments)

uh, yeah, a Ph.D. in mathematics might once have been a death sentence, but nowadays it's more like a license to print money (almost literally, in the case of Wall Street) if you're willing to hold your nose, check your ego, and get back out of pure math.

similarly, a four year math degree from a respectable (not even necessarily great) university, coupled with the right research experience, extracurriculars, and/or job experience/internships, is a solid credential. maybe not as much of a sure bet as engineering, but pretty damned good and much better for certain specialized areas.

For Half, Degrees In Computing, Math, Or Stats Lead To Other Jobs

retchdog Re:um (174 comments)

Yeah, I can tell you that a CS "degree" which involves being "specialized" in a particular programming language is a bullshit trade diploma. It's not surprising that such an applicant is garbage; degrees in programming are for idiots. Smart people program on their own, or go to college for formal maths/sciences, or ideally both.

Researchers Design Bot To Conduct National Security Clearance Interviews

retchdog Re:Huge Issue (102 comments)

given your ridiculous hypothetical, i think i'd take the one with the minor arrest. it shows that he is willing to socialize and take moderate risks in a social setting, while still performing equally to the poindexter.

on the other hand, even a 5-minute interview would probably give me more information than a list of mostly-bullshit "accomplishments", so whatever.

Why My LG Optimus Cellphone Is Worse Than It's Supposed To Be

retchdog Re:original title (290 comments)

i never said that your statements were correct. i was being rhetorically generous.

as for the rest, i don't see why i should give advice on a business plan, for free, to a self-described "entrepreneur."

Why My LG Optimus Cellphone Is Worse Than It's Supposed To Be

retchdog Re:original title (290 comments)

on behalf of a math student (myself), i will mention that there are literally an infinity of statements that are not "incorrect". some very basic software can enumerate millions of "theorems" within a few hours given appropriate axioms.

this list of facts will not, however, have any point; it will just be a list of correct statements.

simply because something is correct, doesn't mean that it is worth reading. this is the problem people have with you. your slashdot articles are vapid and narcissistic, and you doggedly persist in ignoring (or pretending to ignore) this. that is the point and it's been made ad nauseam.

Critroni Crypto Ransomware Seen Using Tor for Command and Control

I think he has... ahem... balls to assert such a contrarian viewpoint on slashdot.

But, yeah, he's a loony reactionary. Just ignore him or laugh at him. "Collaborator" is a bit too generous.

X.Org Server 1.16 Brings XWayland, GLAMOR, Systemd Integration

retchdog Re:So... (226 comments)

whether all trolls are psychopaths is another issue. pop psychology isn't that impressive to me.

i'm not trolling, i honestly don't understand. you seem heavily invested in this issue, and since you've already spent a lot of time on this topic (judging from your posts here), i thought you could explain it to me briefly. i can only conclude that you just don't like systemd, and are upset because something you don't like has become popular. maybe i've already read those articles and simply disagree with them. i just wanted your opinion. disagreement isn't trolling.
