Since you seem to have insight into this stuff, what's the best way to treat a serial stream as keypresses? Say I have an embedded system receiving a continuous stream of serial data, but I need to look for sequences of six or seven hex values and treat the various detected sequences as keypresses, where do you suggest I start? How about a method that will not affect the system if I want to occasionally attach a USB keyboard?
I used a kit from avelectronic.com to convert my nav screen to also be a tv with 3 a/v inputs. I bought it not for the tv, but to run video out for a micro PC mp3 player. Since I don't want to have to come to a complete stop to do simple tasks like selecting a genre to listen to, I need the video to stay on all the time.
Their "safety" line forces the screen to go blue until it gets grounded. Apparently, there is a special nut that gets grounded when the emergency brake gets applied. As you could guess, any permanently grounded nut or wire is all you need to circumvent the safety feature.
Yes, I am taking on a big responsiblity to not watch videos, but I am adult enough to do that. I do like to put the evening news on while I'm driving home from work. Plus, the unit will drive video to the nav screen and has two more outputs to drive rear-facing headrest screens, and I can shut off the video to the nav screen without interrupting it to the headrests.
Its all about the maturity and responsibility of the driver. Sure, it always has been, but now more than ever with so many distractions available.
The last one I dealt with came to my attorney sending him a certified letter saying we were going to take him to court if he didn't produce a refund or my merchandise.
It goes the other way, too.
The other way? I still didn't get the first way yet!!! This guy told your lawyer to sue him? What a goofball!
YARDLEY!?!?!? Me too! My development off Heacock can *never* get DSL b/c they ran fiber from the CO by the duck pond to our distribution point and then copper to the units. The Verizon CSR suggested that I walk up to the Verizon truck with a $20 bill (or a sandwich) if I see some guys working and ask them to try to track down any unused pairs that may have been run straight thru for some now-unused ISDN.
I didn't need the $20 when I asked, but the guys couldn't find any pairs. My Comcast cablemodem has been doing fine for a couple years now, and work pays for it. Is that your Saturn I've seen around town with all the/. stickers all over it?
NEVER had a kernel panic due of hardware misfunction or damage
While I haven't had a panic in years, the last batch of them I was experiencing were due to an Adaptec 1542CF (ISA SCSI controller with a floppy port if you don't remember OLD hardware). The machine would panic several times a week (and this was before ext3 so I never knew if it was going to come back), sometimes panicking if I bumped the case with my knee!! I couldn't WAIT to get rid of that card.
My biggest frustration right now is that IBM put out my T41 without any Linux drivers for the built-in 802.11a/b/g card. Yes there's an OSS solution out there (that I *still* can't get to work), but IBM should never have let that happen. It looks pretty bad in front of customers when I have to put my Orinoco Silver in for wireless when I reboot to Linux and remove it when I bounce back to XP.
For example, it would be nice if I could get to my campus email through a secure POP link. But the server doesn't have one enabled. Well then, say hello to PINE, via ssh
If you have a full shell account on the remote end (i.e. pine doesn't start automatically upon login, and you don't exit when exiting pine), read this to learn how to automatically pull down your email with pop3 over ssh without entering passwords. Works great.
I was also going to make a crack about how reading CIO Insight, Outdoor World, and Seventeen should get you some interesting looks from the mailman.. but I forgot:)
I subbed to Linux Journal and SysAdmin for years, but LJ seems to reach a point where it just cycles back to newbieville once or twice a year and SysAdmin is much more mature about things. They both eventually piled up way too high and now I only buy the latest SysAdmin CD-ROM once a year. Its up to like 12 years or something now, with a searchable web interface. Can't be beat. I get to give my hand-me-downs to my friends.
I also can't get rid of Dr Dobb's Journal no matter how hard I try. I friggin' hate that pile of crap -- I mean waste of trees. Finally, the only paper mag I look forward to are the quarterly publications of IBM Systems Journal. $105/yr, free to IBM employees. 200 pages of ad-free, hardcore tech theory each quarter. It takes a few months to read each issue, too! It truly is a "journal", and not a magazine by any stretch of the imagination. Also, it gives me a great head start on what technologies IBM (and I as an architect) will be delivering to our customers over the next several months to a year. If you want ad-free, hype-free cutting edge tech theory with nothing but deep-dives, find an IBMer and ask them to subscribe! Its an incredible read. Oh, and I have unlimited access to Factiva.com, too.

Thanks for the undeservedly calm response. I'm sorry I freaked out on you. I just can't stand how you positioned yourself as against anything that the service "was not originally intended for". In my calmer voice, *that* is the single worst attitude to have in the hobby, and that is what causes the most harm. Our bands are under fire every day, and if you keep turning interested newcomers away because they want to do something that wasn't envisioned in the 20's, that is a real problem.
You basically told that guy "don't bother becoming a ham because we don't want you checking your email here". What was particularly grating on my nerves was the way you emphasized RADIO, implying that phone or cw are the only acceptable modes.
Yes, you had me extremely pissed off, and while I appreciate your demeanor, I still don't appreciate your attitude about what's acceptable in our great hobby.

The Amateur Radio SERVICE was never intended (nor needed, IMO) as a path for checking one's E-mail
I think you realize by now just how damaging you are to our great hobby. Part of what makes amateur radio great is that people come up with new functions and uses all the time. Can't stand digital modes, huh? After 27 wonderful years making terrific contributions to the hobby like this little gem, you must have learned the phrase "use it or lose it". Did you know that we have frequency allocations above 30MHz? Did you know that those frequencies could be worth a crapload of money to the FCC and commercial interests? Think about this for a second. In the 10GHz band **ALONE** we have 500MHz. About 100 times what you HF bigots use. Maybe we want to do some more interesting things than just pound copper. If you want to learn about the exciting forefront of ham radio technology, check out the Icom D-STAR system. It lets us run voice and 128k data streams simultaneously on 1GHz mobiles and 10GHz backbone links. Boy, 128k continuous data streams. That must really chap your ass. What are you doing to help us keep 10GHz? Running a 1/4-watt CW beacon? Gee, thanks.
You sound like a crusty old curmudgeon.. looking up your call to see how much longer you're going to be around to "help" the hobby. Crap, born in 1960. Looks like you'll be around for a while yet. May BPL piss you off enough to sell all your gear.
the Metro Indianapolis Area contains have of the population
When you people make egregious errors like this, is that you can't spell or is it that you really have NO IDEA that you're using the entirely wrong word for the context? I mean, if you're going to call someone an idiot, well, "po-dunk hill billy", don't make yourself look just as idiotic. Go ahead, make me a foe. You'll permanently metamod yourself to -6. Of course, I'm still looking for the downside.
FWIW, Ben Franklin came up with the idea as a way for farmers to more or less work with the sun (and not be vastly different from city folk's schedules) in the 1700s
It goes a LOT deeper than that. I gave the totally wrong description (i.e. farmers) to my friend's kid and ended up having to look up the correct info. It had a lot more to do with train schedules than with farmers. Keep in mind when ole Ben was living in my 'hood, the size of the U.S. wasn't anywhere near what it was 50-100 years later when the trains really brought the issue to a head. There's a TON of history between BF and the oil crisis. See here.

Can't be cooperating too closely if they don't even know their name.
not sure if you mean RDP the protocol or if there is an app called RDP, but when I use rdesktop on a local LAN connecting from a fully updated RH9 box to a Win2k server, I literally have to wrap the command line in a do ; rdesktop server ; done loop because it crashes every 2 to 5 minutes. It may be quicker but the protocol SUCKS in my experience and collapses wayyyy too frequently. My customer won't install VNC, either, which sucks since with TS you can't (deeply) admin a server anyway. Hell, some people here still insist on configuring NetMeeting to accept all calls and automatically share the desktop with all callers! Dumb asses.
It is sad that IM isn't seen as a series of interconnected networks (like email...):(
Which is what makes Jabber (the protocol) so nice. Oddly enough, I credit MSN with implanting the idea in peoples' heads that an IM nick should be an email address because that's directly compatible with Jabber's line of thinking.
Personally, I'm a bit surprised that more email hosting services don't offer Jabber. It would be SOOOO easy, but they just don't do it. My email has been hosted on a Linux box in some guy's closet since '95 and I was the one who finally got around to running a Jabber server on the box in userspace late last year!
Just wrapped up a killer vaca driving from Philly to L.A. and back over 2.5 weeks. I recently converted my nav display to also be a tv with 3 aux inputs, and I'm now building a mini-itx based carputer. I sure wish I had the 'puter done before the trip, because open wifi is great for pulling down the latest weather radar loop. BTW, the plan is to run Myth in the house and build a menu system for the car to let me select shows for rsyncing and local playback "on demand". Gonna need LOTS of wifi for that!
a high up manager at Digital Equipment Corp (when it was that) didn't have a computer
I'll see your "high up manager" and raise you a CEO;) One of the first things Lou Gerstner did when he came in as CEO at IBM was to insist on getting a PC setup in his office so he can reply to his emails. "And this was at IBM!" When I had breakfast with him last year, he asked me to come to his new office and configure his Notes client to pull email from both IBM and his new company's mail servers, since his new tech team can't figure it out. No, I didn't take him up on it:)
Being a ham, I instead prefer the thought of draping fiber all along the powerlines with 802.11 APs at the towers or every third telephone pole. Of course, that would shut down our HSMM efforts just getting under way, but it would certainly provide a nice web of wifi coverage.
Not sure if you've ever been to Times Square, but imagine if you will a loudspeaker in times square that rebroadcasts (very very loudly) whatever it picks up via its wireless microphone receiver. Now there are about 4 people somewhere in a 10 block radius of that loudspeaker and they are using the loudspeaker to make everone's life miserable. By your account, they should leave the loudspeaker alone, but instead search every single apartment and office within a 10 block radius of that loudspeaker looking for the 3 or 4 individuals with the wireless mics that are transmitting to that speaker. The rest of us here just want the damn loudspeaker smashed to bits. Locate loudspeakers, smash to bits, repeat as needed.
Again, if you've never been to Times Square or midtown Manhattan, you just can't grasp the magnitude of the metaphor.
I have been suffering through 3000ms pings for the last week or so, and I want Comcast to do just about anything they can to neutralize the problems their braindead users are causing. Block inbound, outbound, whatever, I am so pissed off, I could care less. We pay for web surfing and access to their email system if we choose to use it. STOP RUNNING SERVERS AT HOME PEOPLE. Yes, I know well-configured servers probably aren't causing the problems -- look at my UID before replying -- but your constant abuses of the TOS are contributing to the overall detriment of the system.

Not as a configuration tool!
and the console spits out junk until you close that shell.
