Check this page for a cheap ($59), battery operated data logger that records temperature and relative humidity. Stick them whereever you want to collect information. There is a simple Windows program for downloading measurements and configuring the devices over a serial interface.
While it would be nice to be able to run Linux applications on any piece of IBM hardware, Linux will never be a replacement for MVS or OS/400. Those operating systems have capabilities that will never be replicated in Linux. The question is, do you need those capabilities and are you willing to pay for them?
Looking at the front panel of the device, can you tell me what state the system was in when the power failed, can you tell me what state the system will come up in when power is restored? Can I easily "safe" the system so that nothing bad happens to the equipment while the power company is busy doing evil things to the power feed?
WATFOR and WATFIV ran on time-shared IBM mainframes (360 series), at least when I used them many years ago. I'm not sure what they have in common, if anything, with WATCOM FORTRAN-77.
The code dates back to the PDP-11 era. You know, 16-bit CPUs, magnetic core memory, UNIX V7, etc.
So no, it doesn't take advantage of the 256-bit quantum stabilized hyper-transport bus in your PC.
If you think your typical FM station is going to broadcast CD quality music, dream on. They are incapable of broadcasting FM quality music. The average FM station has a program director who doesn't think his signal is competitive unless every last decibel of dynamic range has been exterminated. They use multi-band compressors to get 100% modulation in every frequency range. They don't care if it sounds like shit, with high distortion and no dynamics.
You couldn't legally manufacture and sell a 1950s style TV set today. It wouldn't have a UHF tuner, closed caption decoder or V-chip, all of which are mandated by law and/or regulation.
I've seen figures that about 85% of homes have cable or DBS. What that overlooks is that there are a large number of additional TV sets in those cable and DBS homes that rely on OTA (over-the-air) reception. In other words, the main TV set in the living room is hooked up to cable or DBS but the other sets are not.
The 1962 All Channel Receiver Act empowered the FCC to mandate the inclusion of UHF tuners in television sets. It also allowed the FCC to set technical standards (such as maximum noise figure) for the UHF tuners.
He asked me: "When did we, the public, without which public television would not exist, vote that we wanted to move to digital television? How is it in the public interest to move public programming to a new standard for which most people don't have televisions and which will eventually necessitate the the purchase of a new set?"
To misquote someone, "The public is an ass". The public in not informed or competent to make decisions about spectrum policy and management. That's why we have the FCC.
There are two major reasons for forcing a transition to DTV.
Analog NTSC broadcasting is a very inefficient use of a big hunk of valuable spectrum. The same number of stations can operate in a substantially smaller frequency allocation if they use modern coding and modulation techniques. This frees up spectrum for other uses.
The new spectrum can be auctioned off to raise money for the government. Some of it is also reserved for public safety and other noncommercial uses. It was the need for additional spectrum for public safety communications that initially got the ball rolling on DTV, many years ago. It was this "threat" to the NTSC television frequency allocations that led the NAB to look for ways to justify their occupancy of this increasingly valuable resource.
That should work great, if the receiver has good specs for selectivity and dynamic range. The problem here is that we are dealing with consumer electronics, where cheap is much more important than good.
When I lived in Hawaii, most network television programming was shipped in from the mainland on videotape. Only special programs, like the evening network news, were sent via satellite.
Many syndicated radio shows used to be distributed on LPs, you know, the big round black vinyl things.
The paper size is an integral part of the document design. If you want to support Letter and A4, you need to create two versions, and check them both for problems. That is a good thing, not a bug.
With PDF, you know how the document is going to look. It isn't going to get screwed up by all the things that can change the appearance of a Microsoft Word or HTML document, such as fonts and printer drivers.
I was just irritated by the ignorance of the original poster, who assumed that you could just slap a CD-RW drive into some random piece of big iron and expect it to work.
The problem is, as you noted, that it is easy, and procedures exist, to dump data to tape. Extracting the data, moving it to another system, and reformatting it for PC file formats, is not so simple.
That's one of the advantages of conventional launches with liquid-fueled engines. You can start and test the engines for proper operation before you commit to a launch by releasing clamps or blowing bolts to release the launch vehicle from the pad.
Collisions do not mean data loss on Ethernet. They are just a method of arbitrating for the wire. The link layer will automatically detect the collision, back off and retry. No data loss occurs unless things are hopelessly screwed up.

I have one at home and it works great.
Not necessarily. Encrypting with key A and key B is often mathematically equivalent to encrypting with key C. It may not be any harder to crack.
There may not be "secret patents", but there are patent secrecy orders. See this page.

The first FCC approved color system (CBS) was not compatible with the existing monochrome television receivers.

How are you going to run rzsz over a 3270 synchronous serial interface? Have you ever actually used an IBM mainframe?

We aren't talking about peecees, monkey boy.
I believe the DVD has a peak rate of around 10 Mbps. The average rate is 1/3 to 1/2 of the peak rate.

What's the deal with Baywatch? It seems to be extremely popular outside the United States, even though it gets mediocre ratings in the United States.
