The cool thing about CDMA is that it won't work without precision time standards in each of the base stations - i.e., GPS receivers with antennas fed through known lengths of feedline (or, alternatively, GPS receivers with known lengths of wire providing a 1 pulse per second reference). Net result is that CDMA can give sub-ppb time reference, and it works great indoors, too. Probably overkill for getting the kids up in the morning.
...or maybe it's just required that people named Jean-Luc go into astro/planetary/aerospace lines of work.
Bobby? Bobby Tables? Is that you? Haven't heard from you in ages, dude. What have you been up to? Things went to pieces here right about the time you left...
41% of those actions occurred in Puerto Rico, with the number two favorite being Colorado. Looks like two field offices care enough to investigate, most of the time.
The FCC has, over the last couple of decades, gone a long way toward outsourcing radio regulation. Now, they're predominantly a finance agency conducting spectrum auctions and counting on competitors to police each other. Often, this actually works. Sometimes it doesn't. To be sure, they do have some field-based, rapidly-responding capability to identify interference, especially for (and between!) public safety users, and they occasionally use this to levy big fines to scare everyone else into compliance - I wouldn't want to absorb the typically $11K fine, personally. But their enforcement division is nothing like it used to be.
As far as what used to be called "type approval" (the pre-marketing certification that a device is compliant), it is now 100% outsourced. The fees for this run between $100K and $500K, depending on the complexity of the device and the section of the FCC regs you have to be compliant with (47CFR). 47CFR95 devices are cheap, 47CFR90 devices aren't. 47CFR5 devices can (usually) be self-certified, but they can't be sold.
So, unless Open Source drivers can be sold and operated under Part 5, and it's totally not evident to me that they can, then certification cost is going to mean that someone if going to have to pick a tiny handful of reference devices, certify some binary blobs, and call it done. My guess is that those someones would be Red Hat and quite possibly Lenovo - the one and only marketable Linux Laptop would perhaps be enough of a niche to pursue. In principle, someone like, say, Intel could certify a blob for a mezzanine card and sell the card to vendors, but bear in mind this means the antenna must be fixed onto the card and certified as a package.
Sorry to be such a downer...
Hmmm. If I degenerate enough, and if I just happen to be in Walking Dead country, then yeah... I might visit the place. But that's two unlikely things that have to happen at the same time.
If you're reading this article, you may also be interested in the E. H. Danner Museum of Telephony located on the grounds of Fort Concho National Historic Landmark in San Angelo, TX. While there, you might as well see the Robert Wood Johnson Museum of Frontier Medicine, also on the grounds. Don't go on a full stomach. And that's about all there is to do in San Angelo.
Word doesn't even completely interoperate with Word for Mac, as far as that goes.
Still, you could have a lot of fun with someone... this is the sort of thing that happens when you google "dental robot vomit":

Yeah, I'll take $20 on the 'hog.
I'm starting to suspect we're in violent agreement here.
I've physically, with my eyeballs, seen Linux running on some sort of z series a couple years ago. I saw AIX/370 running on some sort of box around 1990-92-ish, so I know it can be done (parenthetically, I was told it shared no code at all with AIX/6000). My entire point with virtualization is not to suggest there's a problem with the mainframe. Whether it makes sense to or not is completely beside the point.
Z series and power definitely do not share an instruction set, and they have really substantial differences, but that isn't keeping the engineering teams all that separated, if indeed they are at all.
Quoting Timothy Prickett Morgan from http://www.itjungle.com/tfh/tf... , "And as has been the case in the past, the Power and z processors are designed by a single processing team and are borrowing technologies from each other. This does not, however, mean that IBM is creating a converged processor that can support either Power or z instruction sets." My hazy memory makes me think they're sharing FPU blocks, possibly one of the bus interfaces, and it seems like one of the cache blocks (L3?). Z has plenty of custom hardware - I think it's fair to say it's predominantly custom - the branch predictor would have to be pretty different, and of course power doesn't have a BCD arithmetic unit.
Point being, if you're going down the Z Series road to run a Unix-like OS, why not just (conceptually) stop early, end up with something like Power, and call it good? Anyway, I'll argue that they're spiritually and economically related, and there's more than a passing family resemblance. Kind of like power and modern ("advanced server") iSeries, though that's getting more into Deliverance territory.
Meanwhile, channel controllers aren't as dumb as they look. A little wikipedia action here (I know, citing wikipedia, but it's monday and I'm still tired): https://en.wikipedia.org/wiki/... . Turns out the little dickens can do a decent amount of work on its own. I think the wikipedia entry is showing its age... seems like IBM's done a lot more work since this.
I remember when SASI came out. I looked at the spec and thought "Hey, this is a lot like a channel controller." Then I read some more and decided "No, a channel controller is much smarter. But this isn't bad." SASI became SCSI and everything else flowed downhill from that. At a very real level, Linux is forcing a million dollar fibre channel array to look more or less like an ST506 connected a board from 1984. Wild.
It's not the mainframe that's so bulletproof. It's MVS. And, as you noted, an extremely risk-avoidant culture.
Yup - first thought that ran through my mind: "Oh, they're selling Z Series with crippled Firmware."
I'm kind of stumped. Linux on a Mainframe is a neat party trick, but it doesn't really make a lot of sense. Modern Z Series hardware is heavily derived from Power. Why not just run Power Linux? Mainframe I/O design is intentionally about as un-PDP-like as possible, so it's a bad match for Unix, Linux, or even Windows for that matter (NT ran on MIPS, so it theoretically could be ported to S/390). Mainframes get their performance by pushing computation into the channel controllers, and while you could do something like that in Linux, are any of your applications ready to treat your database like a device driver? Because that's what you'll have to do. And, incidentally, it's why every attempt from AIX/370 to Linux on Z Series has required virtualization and a ton of independent kernels to get anything resembling decent performance. And that's where Dell will come in and put thousands of cores in a 42U rack for you... No, IBM's own P Series is a better idea, and their former x86 division (now Lenovo) looks even better.
It is masked but always present. I don't know who built to it. It came before the first kernel.
