A popular survival strategy for many insects is to synchronize their breeding so that they produce a huge number of offspring within a short period of time. The predators can stuff themselves silly but there are plenty of survivors.
An ATSC HDTV signal is about 19 Mbps, or about 8.5 GB/hour, assuming that the video is actually using all of the available bandwidth. A digital standard definition (480i) signal would probably be about a quarter of that. That seems well within the range of today's commodity hardware. The trick is to get the digital video out of the ATSC receiver without Disney, CBS and the MPAA going nuts about piracy.
It's my understanding that SUVs and Jeeps are inherently susceptible to rollover due to their high center of gravity, which is the result of designing a vehicle with a high ground clearance.
I was warned about it during a military driver training course many years ago. They told me that high-speed cornering in a Jeep was a quick way to kill yourself.
A better movie is the 1962 film The Day of the Triffids. Everyone stays out late to watch the pretty meteor shower (the fools!), not realizing that it is causing serious eye damage. Most of the world is blinded, except for a lucky few like our hero, who had been in a hospital bed with his eyes bandaged. Cue the carnivorous plants, who think blind people are very tasty.
The number is about 85%. The catch is that many households included in that 85% figure have additional sets that are not connected to cable or satellite.
ATSC is substantially more resistant to adjacent channel and co-channel interference. This allows the FCC to be more aggressive in channel planning, reducing wasted spectrum.
How does copyright law apply to corporate documents like these? My understanding of current copyright law (post Berne Convention) is that just about anything is copyrighted when it is "fixed in a tangible form of expression". Since this isn't a registered copyright, a civil suit would only be able to ask for actual damages, not statutory damages. Since the commercial market for internal memoranda and emails is negligible, there are no actual damages.
Have you heard of Major Edwin Armstrong and the Yankee Network? Armstrong invented much of what constitutes today's radio technology, such as the superheterodyne receiver and FM. He built an early FM broadcast network that operated in the 40 MHz band. After World War II, the FCC reallocated the 40 MHz band to television and created a new FM broadcast band at 88-108 MHz. This effectively killed the Yankee Network and made existing receivers worthless. The sad thing is that Major Armstrong had made such vital contributions to the war effort, and the FCC stabbed him in the back, urged on by large companies like RCA, who had major interests in AM broadcast networks and technology.
ATSC makes more efficient use of the RF spectrum, allowing the same number of stations to fit in a smaller band. This frees up spectrum for other uses. Take a look at a spectrum allocation chart, television broadcasting is a major spectrum hog.
There are very few "unused" VHF channels in metropolitan areas in the United States. The FCC has complicated rules and mathematical models that they use to assign channels to television stations. The simplified version is that you can't have two stations on adjacent channels in the same area, and you can't have two stations on the same channel in adjacent areas. Foe example:
Philadelphia: 3, 6, 10
Baltimore: 2, 11, 13
Washington, D.C.: 4, 5, 7, 9 (there is a 4 MHz gap between channels 4 and 5)
Once the transition is complete, some band segments will be auctioned off for new communications services and other band segments will be reserved for public safety use. The UHF TV band will become smaller, losing some of the high-numbered channels. This has happened before, when the FCC reclaimed channels 70-83 for other uses.
The NSA has provided encryption systems to countries all over the world. The catch is that this has been limited to the governments and armed forces of friendly countries.
You can export strong encryption if you get an export license. The U.S. Government will grant a license if they think it is in the national interest.
The United States and Canada have been cooperating in communications security and intelligence gathering for many years.
The Swiss are already spinning up the gyros in their ICBMs.
Pascal was designed to teach programming to ignorant college students. It is a relatively small language that is easy to implement. Students hate it because of its "bondage and discipline" approach to type checking.
C and C++ are inappropriate first languages for students. They assume a depth of knowledge, maturity and self-discipline that only comes with
experience and education.
At Microsoft, long-term strategy is more important than short-term profits, or customer needs.
When Microsoft dropped their participation in the joint IBM-MS OS/2 project, they didn't just stop developing for OS/2, they killed all of their OS/2 products, ripped out existing support for OS/2 from all of their development tools, made gratuitous changes to Windows 3.1 to break Win-OS/2, and started using DOS extenders that were fundamentally incompatible with OS/2.
I recently tried to email the maintainer of a web page and quickly discovered that the listed email address wasn't text, it was rasterized text in a GIF file. Unless the bot can do OCR, it can't read it. The only problem is that this trick is hostile to the blind.
One project that I worked on had the right idea. The developers delivered a new build by generating a tape with all of the necessary source code. The test group took the tape, loaded it on their system and built the system from scratch. This ensured that what was tested and delivered matched the source files on the tape. Even with a good tape, you still have the problem of exactly recreating the build environment.
Swarthmore may not have one, but many universities have law schools, with the associated faculty that is already on the university payroll. I'd like to see them try that with Harvard.
I get tons of spam from Russia. 99.999% of it is in Cyrillic, with Russian phone numbers and addresses. That's a damn ineffective way to sell anything to your average American.
The registry does not have to give out their list to spammers. They can require clients to submit a list of email addresses, delete any addresses that are in the registry, and return the modified list to the client.
Linux has already been ported to the CPU used in the HP-49G+. See here.
Wedging it into the limited memory of an HP-49G+ is left as an exercise for the student.
My guess is that it was cheaper to write a Saturn emulator for a modern commodity processor than it would have been to design a modern version of the Saturn, which is an ancient design on an ancient process. If you look at the spec sheet for the ARM variant (S3C2410X01 RISC Microprocessor) that HP is using, you will see that it has a ton of integrated goodies in addition to the ARM core. That's a lot of logic that HP doesn't have to design and test.

Really, I thought it was the cross-polarized emission of tachyons in a Potrezebie field.

No need to involve working engineers or people who have real world experience implementing similar systems. Right.

The FCC tried that with AM stereo. That was a major disaster.

Almost all calculators use BCD floating point, so a floating point unit that uses binary floating point is a waste of silicon and batteries.
