  1. Re:Also used in Intertec's Superbrain on Zilog To File For Chapter 11 · · Score: 2

    That reminds me. I think the MFM controller in my old ALR 386/2 used a Z80 chip. Those chips did get around but then an entire generation of engineers learned the 8080 or Z80 instruction set in college (another big one would have been the 6800/6502). It's not surprising to find the chips in lots of equipment designed in those days.

    The smiley indicates that you were probably joking.

They probably want to use Windows CE, too. Just you wait. Laziness will result in your ``smart'' kitchen appliances requiring muffin fans to keep the processors cooled.

    ``Not quite. Spread Spectrum is like pseudo-random radio "noise", constrained within a defined spectrum. Such transmitters have the effect of raising the "noise floor" in the spectrum they're using (and thus the error rate of the channel).''

    Bingo!

    It's been a number of years since I was involved in this sort of work (so my memory may be a bit fuzzy) but this is an old problem. I was part of a group of engineers that were developing software to predict the problems that proposed FM transmitters might have on instrument landing system receivers. If you look at the frequency spectrum allocations you'd say that there shouldn't be any problem. Different frequency ranges so no problem. Right? Wrong. The landing system receiver receives all the freuqncies that the antenna picks up. Some of those FM transmission frequencies combine in the receiver's front end to generate harmonics that are in the landing system frequency band. Some ILS receivers are better than others at rejecting these but the point is that they're there and they affect the S/N (adversely) and degrade the landing system's performance. Not something you want happening. I recall some of the flight tests where other people were collecting real data to confirm out models. In one case, where the technicians had tapped into the guts of the ILS receiver, they could actually hear the audio from a nearby radio station. Similar concerns about interference of the ILS signals had to do with cable systems. You think your local cable TV provider is ensuring that all the connections on the poles aren't leaking RF energy?

    And, if memory serves, lowering the S/N in a spread spectrum has an adverse effect on signal acquisition and tracking. Won't it be fun when everyone in the neighborhood has a spread-spectrum connection to the internet and you find that it performs like a dialup connection.

    And I just love law professors who spout views on technology policies without having the necessary technical background. Just about as much as I enjoy professional politicians doing the same thing. There are technical reasons why the spectrum is/was carved up into protected bands. The trouble with politicians (and law professors who probably want to be politicians) is that they're mainly concerned with the economic aspects of spectrum allocation. And, IMHO, that's dangerous.

    I'm sure that if I were in college now, Futurama would be the sort of show that we'd take breaks for. When I was in college the show was Monty Python. If the TV in the normal viewing location wasn't working, there would actually be roving bands of us knocking on the doors of dorm rooms that we knew had TVs and commandeering their room to watch the show. We made a lot of converts, too.

    And it's not just for college-age folks. I suspect that mainly us old farts would get the humor in something like `Bachelor Chow' and dog food (``Makes it's own gravy!'' [cringe]). I have to explain some of the humor to my daughters because they're way too young to remember those ancient commercials, shows, etc., that Matt G. is poking fun at. I like taping the show so you can slow it down to see the jokes in the signs and billboards that you otherwise miss.

  5. Could we see the list of website sins? on Homepage Usability · · Score: 4, Insightful

    It'd sure be nice to see a summary of the list of flaws from the beginning of the book? I wanted to see if my pet peeves were in there:

    Load Time

    I hope Nielsen made prominent comments about load time. If I were the guy approving the design of the company's external web site, I'd do the final review offsite where one would have to use a dial-up connection to view the site. That would go a lo-o-o-ng way to reduce the amount of gratuitous graphics that most corporate web sites shove onto their homepages.

    Not Testing with Popular Browsers

    Not testing with all the popular browsers should be a misdemeanor, at least. (IE dominance aside, would it kill 'em to at least try out the top three or four?) True story: Compaq's home page used to have a link to text-only version of the same page. Unfortunately, all the links on the ``text-only'' page pointed to pages that were lousy with graphics and tons of Java/Javascript that crashed the browser that they shipped with their UNIX workstations. So much for text-only. The day after I called their office to point out that I was unable to view their web site using the software they shipped with their OS, the text-only link disappeared from their home page. I can only imagine the conversation between the manager and web page maintainer:

    Boss: ``Hey! People that follow the text-only link from the home page have their browsers crash. Fix it.''

    Maintainer: ``Sure, boss. Just take a few seconds.... Done!''

    And Compaq people who I have to deal with wonder why I laugh when they suggest ``you know, this information is available on the web site''. The thing that pissed me off the most about this incident was that the pages wouldn't load using a browser that they were shipping on the OS CDs. Web pages on the CDs had links to pages on the corporate site that would crash your browser. Pathetic.

    Teeny, Tiny Fonts

    Then there are the web sites whose designers have 20/5 vision (or better) and force you to view the site with the smallest possible font that your browser is capable of displaying. Guess visitors will actually be able decide for themselves what font size is best for the viewer sometime before the heat death of the universe. If we want the ability to choose in our lifetimes, though, I'm betting that it'll only happen after someone shoots all these arrogant designers (``Listen! I'm an artiste! What school of design did you attend?'') and pry their pet style sheets from their cold, dead fingers. (BTW, the line forms behind me.)

    Why do I mention these? Because it appears that 99% of the companies with these broken web pages couldn't care less whether users have an easy time accessing their sites. If they actually gave a damn, they'd stop creating web sites that didn't appear to purposely antagonize their visitors.

    Gotta wonder: Who was it that posted the web page ``Why Web Sucks''? Hopefully it's still around. IMHO, it's still relevant.

    There's a fairly easy fix for this if they'd only read the rest of the HTML language manual or stop using crappy design software: percentages. OK, this might limit them in some small way in that they might have a bit more trouble getting those navigation menues on both sides of the browser window (along with the one they stuck on the top of the window :-)) but, you know, that's just tough. The designers of the web pages are the least important viewers of those pages.

(Probably because I'm more used to real realtime systems like navigation and landing systems.) Heck, MVS or VMS could be considered realtime enough for ATMs and slot machines.

Waltzing into a meeting and stating that you think it's a good idea to increase costs by $300 and all you're going to get is a modest (and debatable) improvement in the user interface might require a lot of justification. ``Because it's from Microsoft'' might not be enough to convince the boss when he askes why you want to replace perfectly good, working code in the product line. Like someone mentioned in another post: A Z80 could do the things required in an ATM. And how much do those cost?

    Personally, it sickens me to see people's thinking limited to single turning of the gears and coming up with a solution without considering alternatives. Must be something they're putting in the cafeteria food in schools nowadays that is dulling their thought processes.

    We do the same thing on our Tru64 boxen. All 3rd party software goes in /opt or /usr/opt. 3rd party executables go in /usr/local/bin. Some executables live in an app-specific subdirectory under /opt and the symlink in /usr/local/bin points to the physical location. It makes OS upgrade time tons simpler. And the first step of our DR plan is to backup OS-related stuff and backup software on special tapes. Those get restored first so that we get a bootable system in a hurry. Then the rest of the software and data can be restored using the 3rd party backup software. None of this would be as easy to do if we had 2000 programs all living under /usr/bin. If Mosfet has a point it's that some distribution vendors make a mess out of the directory structure by dumping way, way too much stuff under, say, /usr/bin.

    Nah. The last job where coworkers used to regularly hang out after work was a long time ago (over ten years). And, actually, we weren't IT workers but rather electrical engineers that just happened to do a lot of interesting things with computers during the course of our work (avionics systems). Another difference was that it was a university engineering/research lab that was involved in outside contract work. I haven't experienced anything like that sort of comradery (sp?) since moving to the so-called ``real world''. Part of the problem, I suspect, is that most of my current coworkers live so far away from work that they're not exactly thrilled with the idea of going out to socialize with coworkers and then have an hour's worth of driving to get home. I floated the idea of a project completion barbeque not too long ago at work and it wasn't received well. That sort of activity was common back in my days working in academia. In fact, I'd say I have closer relationships with some of my coworkers from those days than I have with current coworkers. Part of it might have related to the close working conditions, the stress of meeting the deadlines for deliverables, 18-hour workdays, etc. Not the same as getting shot at or running into burning buildings, mind you (though sometimes it might have been more comfortable having the director take shots at us than sitting in some of his meetings :-) ).
