Yes it has but "it ain't that good". There's a lot of RF noise up there, so they still use air-based platforms such as Raytheon ASTOR/Sentinel. They're cheaper as well, even if you need a couple of Tornados to follow it. I'm not saying an

Or so they'd like you to think.

Pretty cool. I was going to get a GUID tattooed to my arm :)

KH-8 resolution is "0.5m". That is analogue as well as they used photographic film in them. This is "0.5m" resolution (from GeoSat-1). http://geoeyemediaportal.s3.amazonaws.com/assets/images/gall...

2-3 feet per pixel. Google earth uses that for imaging at very high scales. They use aerial photography for the rest. Per-pixel, it's definitely mainly aerial photography TBH.

That was their theoretical ground resolution. I doubt they ever achieved anything near that in reality.

I worked for a couple of nefarious organisations over the years. I doubt there is nothing much greater in resolution. There are so many technical challenges such as diffusion due to moisture in the atmosphere that limit things practically.

Sounds very much like the GreenArray devices ( http://greenarraychips.com/ )

This in electrical engineering at least is SNR (signal to noise ratio). Noise is filtered, however the intent is to recover the signal cleanly. Anything which is self-detrimental is likely to be part of the signal, not the noise.

batman -> coffeescript -> javascript. I don't get it. Too many layers of abstraction. I'm having serious trouble with even jQuery (with IE7,8 for example) on some of the stuff I'm working on, particularly on older machines.

tl;dr: "PostgreSQL is still my weapon of choice — it doesn’t keep us up at night." I agree with the guy. PostgreSQL (and SQL server ironically) have kept me up less than any other piece of software out there. I'm watching a turd occuring w

True. Also consider most of the world of Nokia Series 40, which by far destroys any other mobile operating system: "Analyst estimates place the total number of devices shipped with S40 close to 1.5 billion, as of the end of 2010" [1] [1]

Still works though; a thing that many people don't consider!

More context = higher probability of tripping any algorithms?

Sometimes you DO have to rewrite your application, particularly if you build it on proprietary software which has support agreements and EOLs which get hit. For example, look at all the crocks of shit hanging around on COM/VB6. They need

That's what I was thinking. Need some analysis on it really. We throw money at the problem at the moment and it goes away :)

If it's anything like the 300s or the 35s reissue, it's going to be crap. Just about anything coming out of HP since the HP48 is utter shit. For ref the 300s buttons don't work properly and the OS is simply 100% stolen from Casio FX-series

The issue is x86/x64 being a turd. Throughput of just about everything drops when you go over the 36Gb boundary for some reason. I have no idea why. It can drop by as much as 30%. This is from experience operating VMware on the physical

Fair point - I'll give you that. Ironically I did a spot with Intermec barcode scanners and printers for asset management on top of Oracle so I understand where you are coming with. I actually quit because I was the only one who did care.

Having done a LOT of work in that space (historically), I can assure you it's all SAP, Oracle, PeopleSoft, AS400 and epic quantities of turds. The largest turd being EDI and all sorts of nastyness. It's not fun. It's actually painful. It

That's a fair statistical analysis so I get your point. With respect to Usenet, I'd fully expect that the endpoint logs, but not every intermediatary who happens to have an agreement with another intermediatary, which is the issue with tra

It's not about aggregate behavior with millions of others at all. It's about profiling. Consider the case of clicking a link in an email someone sent me for a joke. My google account thereafter managed to associate me with bestality [1].

They exclude transactions because an ORM maintains a stateful copy of the data on another tier. Once a copy is made of the data, the guarantee that a transaction can succeed or the data remains correct is no longer valid. Considering Fowle

It's at the detriment of the user when the iPad is no longer vogue and they wish to retain their books, movies and music.

Thank you for saving me the words. The reason I don't have a Google account is that I don't like being profiled and tracked as I go around the Internet and I believe that pay-walls should not be in front of free information. A Google accoun
