Comment I worked on the project back in '68 (Score 3, Informative) 29

Back in ny early days as a lab techie I was running the optical processor that did the image-making post-processing for what I believe was the first "flyby" / "rotating target" synthetic aperture radar. (No significant intellectual contributions: I was running the machinery, rather than contributing to its design. Adjusting lenses, exposing and developing film, etc.)

Back in those days the computers weren't up to the amount of crunch needed. (This technique is essentially a two-dimensional fourrier transform with tweaks.) So we used laser light and lenses for the fourier transform, and photographic film for the input modulation and output capture. The original data was captured using a one-dimensional CRT with a solid row of fiber-optic light-pipes built into the faceplate. This was in actual contact with the recording film, transferrig the light from the phosphor inside the CRT without geometric distortions from lenses and such. The film was about four inches wide, and the servo capstain that advanced it was a critical component for accurate signal processing, as was the circuitry that linearized the sweep of the beam. The input plane of the optic processor held the film in a xylene solution between two optical flats, to eliminate phase distortion from roughness of the film's surface.

The nice thing about synthetic aperture radar is that the resolution is related to the radar frequencies and the relative motion of the antenna(s) and target, and is not dependent on the beam width of the antenna. (Well, wider beam width means you illuminate the target from a larger virtual antenna, sharpening the image.) Except for deltas, distance doesn't matter, either. You get the same resolution at tens of feet or interplanetary distances. Distance only comes into the pricture in terms of keeping the oscillators from drifting during the transit time of the beam, so you don't introduce varyimg phase errors when down-converting successive returned chirps.

Voting for the lesser of two evils is still voting for evil.

If every single person who said they would vote third party if it wasn't throwing away their vote actually voted third party, we'd see some serious changes. Just accept that it doesn't matter one bit whether a democrat or a republican wins the election. The results will be the same. Once you accept this simple truth, you are free. Now you can vote for a third party candidate without that fear of letting "the other guy" win. Vote third party. Always. I don't care which third party. Just don't vote for the status quo.

Comment Re:Did they restore "delay image loading"? (Score 1) 270

Do you mean the "Load images automatically" setting?

Yes, that's it. (I couldn't remember the exact wording and with it gone I couldn't look it up. B-) )

The preference for that seems to still be in about:config. It's called "permissions.default.image" and the values are documented as: // 1-Accept, 2-Deny, 3-dontAcceptForeign

Geez! No WONDER I couldn't spot it. Didn't they ever hear of mneomincs?

Thank you. I'll give it a try.

Comment Did they restore "delay image loading"? (Score 3, Interesting) 270

I'm at my Nevada vacation/retirement place for the first time since migrating my laptop from Ubuntu 12.04 LTS to 14.04 LTS. This dragged in Firefox 29.0 ("... Canonical 1.0").

The place only has dialup Internat at about 38Kbps. (Somewhat higher speeds are available at substantial cost, which doesn't make sense untlil we're here for more than a couple weeks a year.)

Web browsing was barely usable at this speed by using a few tricks. The most effective one was to configure Firefox to not load images until/unless I wanted to look at them.

When I got out here last Friday I discovered that firefox 29.0 no longer has the radio button in the preferences/configuration menus. An hour or so looking at about:config didn't turn up anything likely-looking, either.

Without this feature, "surfing" the current image-heavy web pages is essentially impossible. Even trivial pages may take a couple minutes to a half-hour to load. PER PAGE.

Did the Firefox crew restore the feature for 30.0? (Or does anyone know where it was hidden, if it still exists on 29.0 and 30.0?)

Developers breaking important features (that THEY don't use) while "improving" products is a real problem.

Comment Fat chance. (Score 1) 247

The Anti-Corruption Act would go a long way towards helping. Lobbying is the major way that corporations influence legislation, and it needs to be completely stopped. It needs to be criminalized.

It will just get struck down, like every other anti-lobbying and campaign funding measure that has finally gotten to the courts.

This is because lobbying is a Constitutional Right. It is called "Free Speech" and "Petitioning the Government for redress of Greviances".

People do NOT lose their free speech and (especially) political activity rights when they are acting in a group, regardless of whether the group is a club, a political movement, or a business.

But such measures, once passed, can do enormous harm before they finally make it to court and being struck (after which another is passed and the cycle repeats). The rich and connected can hire lawyers to find their way through the latest maze of regulations, fill out the bales of forms correctly, defend themselves in court if challenged and bring suits to finally get the laws overturned. Meanwhile we little guys are hosed.

These laws may be well intentioned. Or they may be intended. from the start, to paralyze grass roots efforts while appearing to block undue influence by the rich. But they always give the advantage to big-money and big-connections and always penalize us little guys.

Comment In BLE (Bluetooth Low Energy) it's standard. (Score 2) 323

but changing MAC is like filing serial# off a car! At least according to the prosecutors...

Not any more. The Bluetooth Sig just spent four years in heavy sessions to plug the privacy leak from the MAC address tagging every packet with a device "serial number". This was rolled out in Bluetooth 4.0, especially in the Bluetooth Low energy addition.

If the option is turned on, the "MAC address" that labels the packets is pseudo-randomly chosen and constantly mutating. If the other device trying to communicate has a special relation it can access the true MAC address and/or share the secret so it can predict the pattern of mutation.

Apple went one further, though. Even when the remote device has the option turned off and is using the real MAC address for the link label, their stack doesn't export this info to apps over the API. The apps have to have to negotiate with the far end of the link to get it (or find a way to work around the stack, and risk Apple deliberatly breaking it, or removing them from the app store, if they find out), even though it was already "in the air".

I think Apple is sensitive to accusations of privacy violations and is making it hard for independent developers to put them in legal hot water.

Comment Probably from PKU. (Score 1) 125

Now, where the heck do the blonde jokes come from?

Probably from the genetic metabolic disorder Phenylketonuria (PKU). This enzyme failure, if untreated by a phenylaline-restricted diet, leads to a constelation of symptoms that include mental deficiency, blonde or light hair, and blue eyes.

Interestingly, one of Hitler's pre-war programs was an attempt to breed more blonde-haired, blue-eyed, Germans. The main result was a drastic increase in the prevalence of PKU in the German population.

On the other hand, very pretty women tend to experience a social environment where they are rewarded for interacting with others, regardless of how they are behaving otherwise. If consistently rewarded for any statement, whether right or wrong, they have no incentison learn to use and demonstrate intelligence.

The free market isn't always the answer (and I'm somewhat of a libertarian). All the big iron and big database companies have a history of making big promises, then delivering something that isn't capable of doing what the sales people claimed. They're also experts and hiding bullshit in the contracts so they have their asses covered. But if they were given another few million dollars they can fix things. Pinky swear.

Comment Swamped by environmentalist interference. (Score 2, Interesting) 379

... according to the article there has been a three-decade pattern of fires getting worse in the West:

And the reason for that is well known, and has nothing to do with global warming.

It is caused by environmentalist interference in land management. The major factors are;
  - Fuel load: Logging is stopped, or delayed for decades by lawsuits, even of diseased and fallen trees, which are left to rot. Brush clearing, deemed "unnatural", is also stopped. LOTS of little trees and weeds grow up between the big trees. When a fire finally starts, it soreads rapidly and burns big and hot, and is very hard to control. The hot burning sterillizes the ground, killing many types of seeds that would otherwise have fueled a post-fire recovery.
  - Access restriction: Loggers and other visitors to the area are the main source of reports of fires when they're still tiny. With logging stopped and most recreational uses banned the woods are essentially deserted. A fire that would have been spotted in tens of minutes might have as much as days to grow before it is discovered. Once it IS discovered, the lack of roads and lack of clearng of those paths still there impedes fire-fighting: Regular equipment, or even four-wheel-drive SUV-based, fire equipment can't access much of the area, and must leave those areas it can access early, to avoid being trapped.

I think it's ludicrous that the blame for the anthropogenic forest fire severity increase is being deflected from the policies and policy-makers that caused it and simultaneously being used as additional "evidence" for global warming. It's tactics like this that cause people to distrust global warming claims.
