A Fictional Compression Metric Moves Into the Real World

fnj Re:Trivial observation (130 comments)

The Weissman score is actually unitless. When one divides "log seconds" by "log seconds" the units cancel.

That is because it is presented as the ratio of the figure of merit of the candidate algorithm to the figure of merit of some bullshit "universal compresser", times a completely useless "scaling constant". To strip away the obscuration, all you have to do is see that for a completely transparent effectless compresser, r is unity and log t is log 0, or unity. 1/1, and it drops out.

The underlying figure of merit once you cut through the bullshit is r / log t. r is the compression ratio (unitless) and log t is log seconds. So yes, the units of the underlying figure of merit are reciprocal log seconds.

You need learn to cut through the hocus pocus and analyze the actual underlying equation before the Oz Sauce is ladeled on. You can well imagine that those who actually understand programming metrics are holding their sides laughing at those who are taking it seriously.

The Misleading Fliers Comcast Used To Kill Off a Local Internet Competitor

fnj Re:If... (241 comments)

If absurd postcards are enough to actually persuade a vote, then perhaps the people got what they deserved.

Unfortunately, "the people" is shorthand for a large number of individuals. Yeah, the stupid people got what they deserved, but in no sense did the people with functioning intellects get what they deserved.

The Misleading Fliers Comcast Used To Kill Off a Local Internet Competitor

fnj Re:And this friends, is why buying a voice is wron (241 comments)

You could make voting conditional on passing a test. Not a straight IQ test, although that should be a part of it. Pose some questions on postulated issues and synthetic candidates, and try to find those too liable to being gulled by clear hoodwinking.

Also, and this one is going to be hard to do for a number of reasons, prevent those who are personally turning an overall profit at the expense of the commons from voting. Let there be no stigma to accepting welfare, no matter what the hell you call it (e.g., earned income tax credit, etc, etc), but at the same time if you are cashing in more than you are contributing, so sorry, you don't get to vote yourself largesse either directly or indirectly.

Hey, I said it would be a challenge to implement.

A Fictional Compression Metric Moves Into the Real World

fnj Re:Trivial observation (130 comments)

The reason the Score is utter bullshit is that the scale is completely arbitrary and useless. It says that 2:1 compression that takes 1 second should have the same score as 4:1 compression that takes log(2) seconds, or 1 million to 1 compression that takes log(1 million) seconds.

WHY? State why log time is a better measure than straight time, or time squared, or square root of time. And look at the units of the ratio: reciprocal log seconds. What the hell is the significance of that? It also conveniently sidesteps the variability with different architectures. Maybe SSE helps algorithm A much more than it does algorithm B. Or B outperforms A on AMD, but not on Intel. Or maybe it is strongly dependent on size of source (there is an implicit assumption that all algorithms scale linearly with size of source; maybe in actual fact some are not linear and others are).

In real life, for some compression jobs you don't CARE how long it takes, and for other jobs you care very much. Or imagine an algorithm that compresses half as fast but decompresses 1000 times faster. That doesn't even register in the score.

It's bullshit.

Please explain why you think that means he said "it does work".

World's Largest Amphibious Aircraft Goes Into Production In China

fnj Re:Caspian Seamonsters? (85 comments)

That makes it sound a bit underwhelming. The KM Ekranoplan had a takeoff weight of 544 tonnes. Of that, the weight of fuel plus payload which could be lifted was 304 tonnes.

World's Largest Amphibious Aircraft Goes Into Production In China

fnj Re:Spruce Goose (85 comments)

Timothy had a moment of going soft in the head. It happens to the best of us. "The TA600 has a huge maximum takeoff weight of 53.5 tons". Huge, my ass. The A-380 is 592 tonnes. The 747-400ER is 413 tonnes.

World's Largest Amphibious Aircraft Goes Into Production In China

fnj Re:Spruce Goose (85 comments)

Yeah, except this piece of junk is tiny. It is not large at all. The Martin JRM-1 Mars in 1942 was much heavier. It's a squeaking mosquito next to the Hughes H-4 Hercules of 1947. Yes, shut up, I know those are straight flying boats - because sometimes you just have to make up your mind.

Technically, sure, it's the heaviest amphibian in the world. Amphibians as a class are practically dead.

Meters per second springs to mind. Base units make the most sense.

One Trillion Bq Released By Nuclear Debris Removal At Fukushima So Far

fnj Re:Pick your units of radiation... (190 comments)

For crying out loud, one becquerel is a single ATOM popping its top off. Imagine if we measured visible light this way instead of via lumens. Much bigger numbers.

For god's sake if the simple quantity bothers you for some reason, just call it one terabequerel. I'm sure you'll feel much better about one of something than a trillion of something else. Just like 100 kg is perfectly all right, but my god 100,000 grams? Time for a diet!

Myself, I kinda like calling it a trillion bequerels, because a thousand thousand thousand thousand atoms "popping their tops" is pretty much a fucking disaster, and it's less likely that moronic assholes will just shrug it off.

MIT's Ted Postol Presents More Evidence On Iron Dome Failures

fnj Re:Here we go... (454 comments)

Will Israel promise that if Hamas puts all its rocket launchers, military command and control, and military supplies neatly organised in easily identifiable military bases, Israel won't simply send a missile to figuratively cook all those eggs being put in one basket?

Are you so high you don't realize how stupid that sounds? Why would they do such an illogical thing?

EPA Mulling Relaxed Radiation Protections For Nuclear Power

fnj Re:headed in the wrong direction (230 comments)

So long as people ... live in areas with above-average background radiation

Which is to say, forever. By definition precisely one half of the population live with background radiation above the median level. That can be stated without any knowledge whatsoever of what that median level is or what the distribution is. It is a truism. I'm not aware of the precise statisic for percentage living with above average background radiation, but for example we do know that the natural background radiation in Finland is about three times that in the UK.

Russia Prepares For Internet War Over Malaysian Jet

fnj Re:meanwhile overnight... (503 comments)

Ukraine had some in their possession from their days as a Soviet satellite state

Ukraine was never a "Soviet satellite state". It was an integral republic of the Soviet Union, and the second most important one, from the first year of the Soviet Union.

List of the republics of the Soviet Union:
Russian Soviet Federative Socialist Republic (member since 1922) (population in 1989 147 million)
Ukrainian Soviet Socialist Republic (1922) (52M)
Unbek Soviet Socialist Republic (1924) (20M)
Kazakh Soviet Socialist Republic (1936) (17M)
Byelorussian Soviet Socialist Republic (1922) (10M)
Azerbaijan Soviet Socialist Republic (1922) (7M)
Georgian Soviet Socialist Republic (1922) (5M)
Tajik Soviet Socialist Republic (1929) 5M
Moldavian Soviet Socialist Republic (1940) (4M)
Kirghiz Soviet Socialist Republic (1936) (4M)
Lithuanian Soviet Socialist Republic (1940) (4M)
Turkmen Soviet Socialist Republic (1924) (4M)
Armenian Soviet Socialist Republic (1922) (3M)
Latvian Soviet Socialist Republic (1940) (3M)
Estonian Soviet Socialist Republic (1940) (2M)

The three Baltic republics (Lithuania, Latvia and Estonia) was disputed as an illegal occupation, but none of the others were.

The states referred to in some quarters as satellite states were such as Poland, East Germany, Czechoslovakia, etc. Most of them were People's Republics or Socialist Republics or Democratic Republics, but none had "Soviet" in their name. They were formally independent but heavily influenced by the Soviet Union.

LibreSSL PRNG Vulnerability Patched

fnj Curious OS design shortcoming (151 comments)

Not an expert in OS design details, but I'm quite surprised there exists an OS which newly hands out the same PID a very recent process had. Do not PIDs monotonically increase until they wrap around? If not, why not? And why are they not based on adequately large integers? 32 bits for a minimum; why not 64? Yeah, it will uglify a ps display, but eyes on the security ball here. My 64-bit Arch linux on kernel 3.15 is saying 15 bits (cat /proc/sys/kernel/pid_max = 32768).

For that matter, Is there any reason not to make sure all PIDs issued on a given system for a given power cycle are unique? Yeah, it would be a tradeoff against performance.

NSA Says Snowden Emails Exempt From Public Disclosure

fnj Re:"unwarranted invasion of personal privacy" (231 comments)

could you quote the section of the US Constitution that establishes the right to privacy?

OK, this ring a bell? The right of the people to be secure in their persons, houses, papers, and effects, against unreasonable searches and seizures, shall not be violated, and no warrants shall issue, but upon probable cause, supported by oath or affirmation, and particularly describing the place to be searched, and the persons or things to be seized.

That's the fourth amendment, in case you are at a loss.

It's kinda hard to have any privacy when jackbooted thugs can just bust in and rifle through your effects on a whim, no?
