sorry AC, I've got no mod points for you, but you are exactly right, except in the good old days of NW 3.x , netware admins would laugh at someone bragging about 300 days of uptime. I worked with NW sites that had servers with years of uptime. I've had unix servers that had years of uptime, not that that was a smart thing. It just meant they were running on reliable HW and hadn't been patched for years. With NW you could have servers with years of uptime and up to date SW.

The last NW site I worked at (late 90s maybe?) was shutting down NW servers that had been up non-stop since they were deployed years before to replace them with Windows servers as part of some lame-brained management driven "server consolidation" plan. Wonder how much money they "saved" with that?

Anyhow, great video. The description makes it sound like it was a series of still images in video format, but it was very dynamic (maybe series of stills were turned into video or something - I have no idea).

yes, the video is made from a sequence of 4096x4096 stills. I don't know if the artifacts that you can see in some frames are because the detectors were saturated or they are a result of downsampling and the conversion to video.

agree 100%. It worked for me. I learned physics and astronomy OTJ. I already had the technical skills. Besides the skills mentioned in the parent post, real-time programming and controls can get you into the other end of the process, sensors, and their associated control and data acquisition systems. In addition to the places mentioned above, many universities, national labs and FFRDCs have space science programs. Also, while its totally obvious, but nobody else has mentioned it, there's NASA and its contractors. If you have the skills and you really want to do this you can. You need to use your imagination, keep your eyes and ears open and be willing to relocate.

There has been a satellite servicing project at NASA/Goddard for about, uh, 3 decades. While for most of its existence it was focused on servicing performed by astronauts, there has always been some work going on in robotic servicing. One of the recent accomplishments was a robotic refueling demonstration

The only time the robotic effort was funded it a relatively high level was during the space station freedom era, and that only lasted for a couple of years before congress pulled the plug. To make matters worse, most of the money that was appropriated went to Martin-Marietta for concept studies

Indeed. Back in the '80s when I worked for a Corporation that made Digital Equipment, we had an group that purchased our competitors equipment, evaluated it against our products in the same categories, and published a document called the Competitive Handbook. Outside of our financial information, the Competitive Handbook was one of our most closely protected documents.

Is this: "crappy company delivers badly on contracts" or "company specializes in class of components that have a relatively high failure rate"?

While RWs are way more complex than you would probably guess and have a history of failures across the industry, I still think in this case it is the former rather than the latter. After it started looking looking like there were systemic problems with Ithaco wheels, we developed our own wheels in-house. They haven't been perfect but there have been no mission ending problems with ours (so far; knocking on wood etc), unlike the Ithaco wheels.

It wasn't so much that BASIC was all that much simpler than FORTRAN. Rather that to run a FORTRAN program required mastering not just a little FORTRAN, but also JCL (or the UNIVAC equivalent) and the keypunch. Using BASIC was an interactive experience. The job control and editing functions (as primitive as they were) were built into the language. // EXEC VSF2CG //FORT.SYSIN DD *

no argument about the basic evilness of comcast, but their core network engineers are really, really good.

I'm running V6 at home thru a tunnel and the only major sites that I see supporting V6 are facebook and google.

What this says to me is that the really big players have already gone to V6 out of need, as you pointed out about comcast.

GPM is a joint mission with Japan. The Japanese space agency, JAXA, has provided the primary science instrument, the Dual frequency Precipitation Radar, and the launch vehicle. This is the same arrangement we had with Japan for GPM's predecessor, TRMM, the Tropical Rainfall Measuring Mission. Besides the primary goal of better understanding the processes that drive our planet's weather there is the secondary goal of fostering international scientific cooperation.

Please do not confuse launch services with space exploration. NASA hasn't directly been in the commercial launch service since the dawn of the space age was over. Commercial satellite operators contract directly with commercial launch providers such as ULA, Orbital, Space-X, Arianespace or ILS.

I am in complete agreement with your point about lack of political support for space science and exploration. While there has been no real support for space exploration for decades, the past decade has seen a real drop in actual support (that is, money) for space science. I suspect that is true for science in general, but space is my business.

Serious question - which open firmware is the best choice for current router hardware? years ago, I put DD-WRT on my WRT54g (v2.0) and it worked great, but there's been a lot of forking since then and its not clear at all to me which firmware is the best choice for modern open friendly hardware like the boxes from ASUS.

If you think the system is working, ask someone who's waiting for a prompt.
