Beagles are not Border Collies. I'm glad you enjoy your pets (and I'm not dumping on them).
There is a reason Border Collies, English Shepards, etc, are the norm on farms and ranches. They are quite clever and I think you would have to keep one to appreciate the difference.
I also have a Rhodesian Ridgeback just to keep the proselytizing missionaries away. Sweet but intimidating. I think he would quit breathing if it weren't for autonomous body functions, yet I have met owners who think theirs is borderline canine Einstein. No way.
I never said it was my invention, I said I maintained a system that went into production in 1968.
I didn't maintain it until 1982.
Yes, there was a priority, yes it specified devices and gateways. This was 1968 on TTY (which was carried by satellite, telephone, rusty barbed wire, etc). If you agree that 5 bit baudot TTY and "normal" TTY interfaces make up "industry standard gateways" then yes to that too. Do you know what stunt box does? Hint: it isn't IPv4.
No, we didn't allow users to assign groups. That was an admin function.
My posting was germane to routing messages and prior art. What did you contribute to the conversation? Random hostility and nonsense? Brilliant job, your work is done here.
I personally maintained a system that went into production in 1968 which had twitter like features.
A message was limited to an 80 character TTY line.
The first five characters were addressing information, a space and the rest free form text.
Carriage return dispatched the message which was spooled to drum then picked up and distributed to a single entity or a group (depending upon the first five characters as I mentioned).
This article could just as easily been "Scientists enjoy pleasant week in Monterey".
Seriously, every AI conference I've attended has at least one (silly) panel discussion where presenters free associate and science groupies soil themselves at one turn of phrase or another.
I have heard the same promises/nonsense my entire working career (which started in 1982).
The real debate/idea sharing was at the hotel bar and Markoff wasn't invited.
Yup, I'm w/you. There are several exploits but your point is spot on, old electro-mechanical (read motor driven) consoles/printers were exploitable and this was a well known topic within the TEMPEST community.
For a modern keyboard, not only is it hard to tell the difference between keys but it would be hard to tell the difference between computers as well. In addition to the information supplied above, this is a testimony to modern manufacturing as well (uniform products all make the same noises).
For all the posters who mentions UPS and isolation transformers: you win. An isolation transformer is a typical part of any secure environment.
I sorta miss teletypes. Now that my hearing is fading.
I spent last year converting a shop from OpenView to Nagios. They were in the same neighborhood as you (~5000 devices).
If you do not like the Nagios UI, you could create something else. The native Nagios UI is CGI based and implemented in C. The documentation is good and the sources are well commented.
The hardest decision about Nagios is how to implement the monitoring. I went w/SNMP (polling, not traps) for the most part. Sorting out all the Nagios plugins is something of a chore and many of them seem incomplete and abandoned.
MRTG also integrates w/Nagios, which can be useful.
Face it, if you are asking this question you already have one foot in the grave. Have some dignity and get it over with.
What sort of person volunteers to be a anonymous middle manager at the very big company? I think we all know the answer.
I'm well over 50, I'm still leading projects and actively coding... as a contractor. I get the ageism, and I'm fine w/that. I don't need to work for those people. But I do get tired of the stereotype. There is no rule mandating we turn into lazy semi-retired fossils on our 40th birthday.
Some of you people need to get over yourselves. It is 2009 and coding is relatively easy. The tools are good (hell, when I started you could not trust the compilers) the computers are nice, the networks actually work, API's are complete, etc. Quit acting like you are inventing computer science, because you aren't and it has already been done.
Trunked systems are an OK start, but they depend on a repeater infrastructure that might not be available (never existed, destroyed by an event, obstructed by terrain, etc). Also, there are fleet management issues that need some attention along w/vendor interoperability.
Some of the more cynical comments are probably also true (i.e. pork award to various subs, power grabs, etc). Sad since the whole project is about sharing resources in a disaster. And of course, since this is our friendly public servants at DHS, they will want some encryption lest those pesky citizens leak in.
It is true that SDR makes the de/modulation easy. It is the rest of the infrastructure that needs some work.
Oh, ya. Big risk of litigation. There are earthquakes all the time, who could say if AltaRock was the cause? Easy target for litigation, worthy or not.
I was taking a geology course around the time of the Loma Prieta earthquake. The instructor mentioned several theories for earthquake mitigation, but said the USGS would never risk it because of the potential backlash.
I haven't read the proposal and I don't know the details. But I like the idea of closing the offshore tax havens.
It is hard for me to believe this is even controversial. If a company wants the benefits of US markets, then it should pay the full price of access.
As a small biz owner, I get none of the tax loopholes and I don't find the burden so damn awful. When I want to bring out a new product, then I fund it without government help (I doubt we qualify and I don't need the distraction).
All of you who moan this will just raise prices have it wrong. Put another way, why should we subsidize big companies? You will pay no matter what, and the sale price should accurately reflect the production cost.
I would like to see a comprehensive tax overhaul, but this sounds like a good first step.
You are right, the article is ignorant. But I disagree w/some of your assertions.
Many merships can exceed 30KTS. And so can many large fishing vessels and support craft (by large, I'm talking container ship sized canning factories, etc). They choose the speed depending upon economics.
Yes, a tin can should be able to catch any mership (given enough time). I have personally witnessed a large fishing vessel actually outrun a USCG vessel on fishieries enforcement (which was pretty funny, but it couldn't outrun the helo).
The (*cough*) 30KT figure for surface targets is mostly about supporting a CV at flight opts. This is why the steamers like DD, CG, etc are designed for these speeds. Once upon a time I was on a Belknap class cruiser which blew a boiler. It wiil get your attention.
This pirate issue is old and not just about Somalia (although that gets the news). When it gets to be a big enough problem, then private security will deal w/it.
Oh, and commercial sail is just silly. When people toss around the fuel burn on container ships (etc) they are not saying anything about the tonnage in those bottoms or the dispatch reliability.
I also started on the Sun3 (and I can see a 4.1.3 SPARC CD from where I am currently sitting).
I agree w/you, "baroque" is the correct term.
I wasn't sure if I was still irritated about the switch from SunOS to Solaris or if Solaris was really starting to suck. At least now I know more than one person feels the same way.
I also think some LINUX distros are suffering from the same aging problem.
I worked on the E10K team - we were called "Cray Research" then.
Most people only pay attention to the big vector boxes but Cray also had a SPARC shop in San Diego. There was a Cray blessed version of Solaris and a 64 processor beast called the "SuperDragon".
When SGI bought Cray, they couldn't figure out what to do w/us. After a few weeks Sun got the SPARC shop for basically the cost of inventory.
The SuperDragon was renamed the E-10K, got new colorful cabinets and people started to eat them up. I still don't understand why Cray couldn't have done just as well w/those boxes.
Anyway... I still own a nice SS-20 which I boot up a few times/year (and turn off when I can't take the noise). I am sad to see Sun go (just as I was sad to see Cray and Tandem and other employers go). Hard to believe that IBM will do a better job of managing Sun but we will see.
Oh, now I see your point. What a marvelous invention. Absolutely state of the art. A national treasure. What rare and keen intellect produced such a novelty? Patents are not enough to protect this jewel of western civilization. Clearly, you will be right up there w/Edison and the Wright Brothers. I am humbled to even trade non sequiturs w/such a mighty genius. I will now bookmark your homepage and journal in order to follow the twists and turns of your fascinating career. Lead on, oh great one! Entertain and educate the great unwashed masses!
A sonograph was a common fixture in many DSP shops, I first saw one in 1975. The old ones are mechanical (i.e. there is a rotating drum w/a mag stripe that holds the sample. We wrap thermal paper around the drum and it burns an image of the signal. Could be steam powered, but ours used electricity.
My point is: it's a really old idea and there have been software versions for literally decades.
I wish you well. I live in rural Northern California (Shasta County, near Redding) and we were delighted to get ClearWire and off dial up. I hope you bring us 4G as well.
No kidding. I sincerely mean each and every word of the first paragraph.
However, CLWR is far from a "great company that customers can trust and rely on".
Your help desk people... they are pleasant enough and obviously native english speakers. However, they apparently don't know squat about networking (apart from windoze configurations) and they apparently have no mechanism at all to find a grown up.
I have had serious problems w/DNS and signal quality from time to time, and even when I provide dedicated concrete examples of system failure and a cell phone number, nothing gets solved. I do network management for a living and I would be delighted when someone actually steps forward w/a well defined and repeatable problem.
Seriously, I hope you make it but don't front that CLWR executes perfectly. It's not true. And as much as I like your product, you guys look good simply because all the alternatives suck so much more.
I'm not the poster you are responding to but I apparently live in his neighborhood. You are right, the small airports are the best because we aren't competing w/the big jets for sequencing and the fuel is cheaper, etc. I certainly prefer to go to the smaller airports.
In the bay area, we have San Francisco, Oakland and San Jose airports and several smaller ones such as Concord, Livermore, Hayward, RHV, PAO, etc.
SFO charges landing fees. Don't go there.
OAK has a general aviation runway in addition to long commercial runway. Very nice. The airport management is strangling GA support facilities, but that is another story.
SMF is also pretty nice. They have a dedicated tiedown area for little airplanes (just like car parking). Fly GA airplane to SMF and pick up bigger airplane after the criminal screening. Not too bad.

I am at this very moment looking over my vast herd of 5 Dexters.
Although you mention many relevant items, I am unconvinced of your arguments.
Every *real* cowboy knows a $6 tag is a six pack of real goods, and therefore a poor trade.

Mod up. Right on.
I think the problem at DoD (compared to big 6) is that DoD has too many people who want to bring their hobby to work (and their hobby uses windows).
First hand experience or even minor comprehension of the topic at hand is never required for a comment on slashdot (and might even be a liability).
