Hi, that sounds like an interesting and useful algorithm. You may have better luck trying to publish in a smaller, specialty geomatics journal. Also, you probably would do well to find a credentialed co-author. If you're in Canada or interested in publishing in canada the best journal for this sort of paper would be the Canadian Institute of Geomatics's quarterly Geomatica (http://www.cig-acsg.ca/english/geomatica/authors.php). Good Luck, I look forward to seeing the published paper.
Doesn't matter.. you aren't going to get better than 10m accuracy without DGPS and 1m with it. Surveys have to be right to centimetres - no GPS can do that (possibly some of the military stuff, but I'd be surprised if even they were that accurate).
You don't need military GPS to be that accurate, it can be done with differential phase GPS. See: here. By using a fixed base station at a location with known coordinates, one can expect to see accuracies in the 1 to 2 cm range as long as the receiver is within 10's of km from the base station. There are several manufacturers who make gear that can achieve this level of accuracy, see Leica, Magellan, and Sokkia. I've been using Leica gear at work mostly, and have see ~1cm accuracy under good conditions pretty consistently. A lot of legal surveying in remote areas is done exclusively with GPS, especially in the northern parts of B.C and Alberta. I've done legal surveys with GPS in the Vancouver area, but getting high accuracy in urban areas is more difficult because of multi-path noise and qoor signal quality from obstructions such as buildings. Also people in the city get mad when you cut down trees to get better reception;)
I definitely agree with your post, and having graduated from EE 3 years ago, I don't think I would do it again if I had the chance. I think I would have been served better by taking a few years off to screw around and chase girls, then grab a 2 year technical diploma in a hands-on field that really interests me. It would have been way cheaper and have saved me from wasting the best years of my life closeted up in a dorm room or electronics lab studying.
I get where you're coming from, and on a kind of unrelated note, what's with the demonization of smoking. Smoking kills people sure, but is death necessarily bad for society? By that logic any activity or condition that could potentially kill you is bad for society. People can be killed in traffic accidents, but i think many would agree driving is not bad for society. If there's one thing that is bad for society though, it's sociologists who publish bullshit studies instead of real science.
This has been standard Mac OS operation for a long time. I know for sure that the same happens under OSX 10.4, and as I recall, older versions of the Mac OS (7/8/9) all did the same thing. Granted this is a stupid way of implementing file moving, the alarmist headline is a little unnecessary.
People have been working insane hours for a long time. Insane hours doing sleep inducing jobs on the other hand, is a new things. The Amish don't fall asleep behind the plow.
I beg to differ! As a former dairy farmer (I know! weird for slashdot, but it's true) I have fallen asleep driving a tractor while raking hay. You'd think it would be hard to sleep while bouncing around on a noisy tractor, but I managed to, and even kept my row straight until I woke up at the other end of the field. But yes, a cup of coffee would have really helped me out. And now, back to the usual techy discussion.
I'd have to agree. The guy seems to be making a big deal out of being able to crash Word with a heap overflow buy using a weird input file. The thing to note is that this is a heap overflow, which is much harder (if not impossible) to exploit than the stack overflow bugs that Microsoft has been so fond of in the past. I can see the headlines now "Bug in common word processor could cause loss of unsaved changes if user takes specific action to open a specially crafted input file"... ok maybe it won't make the front page...
I think there's a pun in there somewhere... maybe if we post certain "malformed" puns to slashdot we can cause all the "unsaved" stories from the last few hours to be lost in a similar fashion...
I agree that having something from your travels to bring back memories is important, but maybe for me it's just that digital photos don't do it. I find even ambient audio from some places strikes a deeper chord than most photos I have taken. Perhaps that's the nature of travel for me. I have found that if I ever meet someone or see something particularly striking or interesting, I can always buy a disposable camera or keep a disposable on hand. They're cheap and you can mail the developed photos to someone who can hold onto them for you. Easy, cheap and you don't ever have to worry about stuff getting stolen.
I definitely agree, basically you will have the best backpacking experience if you can fit all of your valuables in your pocket (passport, documents, cash). The problem with cameras, MP3 players, cell phones, and the like is that you have to always babysit them, which is a massive pain while backpacking. Unless you're a good photographer, don't take a camera. Buy a disposable camera and take a roll if you're somewhere really interesting, then you can always mail the photos to relatives or a PO box. Same thing with a tape recorder and tapes, but the idea is that you don't ever have a gadget that would wouldn't mind losing. Being free from worrying about your possessions is half the fun of backpacking. And perhaps with these distractions removed, you'll finally notice that chick on the bus checking you out or the sneaky guy in the leather jacket and sunglasses eyeing your wallet. Gadgets are great, but being free to find excitement and adventure is way better.
Point taken about looking at it from a corporation's point of view, especially when you consider that a lot of self taught programmers really do suck. I think most of my previous comment was motivated by my complete disillusionment with the business world in general.
Good bragging, you must be pretty awesome... But seriously, I think what the unemployed programmers are whining about is the wage disparity between the programmers and CS/Engineering grads like yourself (and myself). I have to agree with this whining because it seems like there's not a lot of opportunity for the self taught/2 year diploma types to move up on the pay scale. Then again, as a starting engineer I only made 45k and worked 60 hr weeks on salary...(which is why I'm leaving the tech field).
You can run OS 9 apps in SheepShaver on an Intel mac, with a bit of fiddling. I've got it going on a new macbook here and it works like a charm. It's not as well integrated into the OS as the Classic Compatibility layer was in PPC OS X, but it gets the job done.
Geez, it's just spam... I can see the guy doing a year or two for the fraud, but the spamming alone doesn't really deserve more than a few months jail time.
Just as a completely unrelated side note: less vs. fewer
fewer -> use when talking about quantized or discrete items.
less -> use when talking about items that are not quantized.
eg. Rapists and murderers usually rape and murder fewer people.
Weirdly enough, the word "more" has no such distinctions. Crazy English!
I say again. A million dollars is NOTHING.
Most "middle-class" Americans think they're rich because they have a Ford Explorer and a DVD player, and a 45" plasma screen tv. They have no idea how poor they are.
One is not truly financially independent until one has probably fifty million dollars in assets
I spilled my coffee laughing! Thanks for the joke, you've made my day... you were joking, right?
Let's see... I generally have anywhere from 30-65 spread across 2 KVM'ed machines, 3 VNC desktops, and 1 RDC connection. Sometimes it's enough to drive a person to want to move into the forest and become a "back to the land" hippie.

Leica System 1200 GPS
I've seen sub-centimeter accuracy while using this device. Although it's a little pricey (approx 30k if i remember), it's still a civilian unit.

Differential Phase GPS is accurate enough for legal surveys (in British Columbia at least... I believe most of the rest of Canada as well).
Btw, IAAS

Since when are subjective observations on a group of people in rooms with different ceilings called Science?
How about: "New study reveals Sociologists unable to cope with the realization that they are not real scientists."
One small problem.
