Re:Other paths to "computer science" careers
PE's are useless outside the civil engineering though. Among EE's they are paricularly scoffed at. The test for EIT certification is so incongruent with modern electrical engineering that even recent (or imminent) graduates take a separate course to master the material. EE's who feature PE's too prominently in their resumes are actually given less consideration than those who don't have them (or leave it off); the reasoning is that such a candidate is looking for a different sort of job than what most EE's do.
It is not impossible to work your way up to "real" engineering, with little to no formal education, even today. It does seem less common than 15 years ago, not that it was common even then. To do that you need to work in a large engineering organization for a long time, a work environment that becomes rarer with every passing year. Most who do that are ME's; I've heard of such EE's & ChemE's but never actually worked with one. I can't speak for CivE's but I suspect that it is rare gven the pevalence of PE certification.
Most EE's who get PE certification get it so they can
- Advertize a consulting shop using the word engineer
- Give expert testimony in court, in patent cases for example. Some go on to get a law degree and then really rake it in doing the most unrewarding work imaginable.
- Be able to sign drawings for particuar sorts of government work.

CoolI played around with Self a while back and was very impressed by the potential of prototype languages. There are some problems, but so many possibilities.
Now there are several such languages available (other than slate). Once they're all a bit more stable (some are stable now) it will be interesting to do a bake-off and see how they compare.
These seem to be the most influential and active (at least at the moment) :
-
Self for solaris, x86, several web sites
- Cecil
- prothon prototype language in the python mood
- IO Desktop
Are there other major/active languages in this vein?

Pine?Will I be able to automatically migrate from my old copy of Pine?
I'm half serious on this, actually. At some point I went all "eye candy" and I do most of my work with pretty GUIs and such. And I still have to open pine in a terminal window and it looks weird.

Re:Stephen Hawkings Kills the Idea of Warp Speed
Note that while that sounds like star-trek babble, it's actually right. There are serious problems with the naive Alcubierre design though, it's not just "exotic energy" you need, you need "negative energy".

Dual mode information
For those interested in dual mode transportation, I'll recommend University of Washington's Dualmode Debate Page. The page mentions all the projects and has a lot of papers describing the systems and discussing the benefits and problems with them.
Also MIT Alumni brought an article proposing the US should invest $1000 billion in dual mode over the next 10 years. According to the author the investment would pay back in only 2 years! What are we waiting for? -
Re:my school
The University of Washington (when speaking of their general computing lab) has a considerable amount of Macs (G5 Towers) but 3 times as many PCs (Dell). This makes the most sense anyway; during 'rush hours', they PCs ALWAYS fill up first.
Thankfully, I don't generally care which I use (well, since Mac OS X came around).
Here's a web site with the UW's tech specs for various labs: http://depts.washington.edu/sacg/facilities/labs/t echinfo.shtml#general -
200 years? I'll raise you 2,200 ...
The idea of software that lasts 200 years reminded me of a discussion on the radio the other day about the origin of a joke: "I've had this broom 50 years, its had 5 new heads and 3 new handles". The identity issue played with here dates back at least to Plutarch's Ship of Theseus - if you keep replacing parts of a thing, until no original parts remain, is it still the same thing?
The relevance to software is captured with an example: Is Linux still Linux? How much remains of the kernel originally published by Linus? Would would you say that Linux has been around for X years (pick X to suit)?
Most people would agree that it's still Linux. What Linux, the broom, and Theseus' ship have in common is that they could be modified to meet the demands of time, while retaining their identity.
I've always thought that maintainability is the highest virtue software can strive for, above other quality-oriented goals like being bug-free, or performant. If its buggy, but maintainable, it can be fixed; if its slow, but maintainable, we can make it faster. I think it could also be argued that software, like Theseus' ship, needs to be maintainable to last 200 years; but the version 200 years from now may not resemble the original in the slightest.
Just my 2c

Re:I wouldn't give them my hard drive...
Unless you are absolutely sure that you have completely sanitized it.
That's where Autoclave comes to the rescue. Your data is as sanitized as you want it to be. It's open source so if you don't trust Josh Larios or the University of Washington web server then you can go ahead and build it yourself.
Of course non-x86 based machines need to look for other solutions but for the vast bulk of business or personal computers, this little program is an outstanding solution to a possibly serious problem.
-
Re:broken laser Printers, be gone!
A warning for those who will be getting rid of old computers: make sure the hard drive is wiped clean (and I don't mean with format). I would recommend using software similar to Autoclave. Every once in a while we get stories posted here about people picking up HDs from eBay and finding all sorts of goodies still on them... Don't be one of those people.

With that out of the way, sorry to say you're incorrect. The cholera toxin is quite nasty, whether you get adequate water/electrolytes or not. Nothing compared to anthrax toxin or botulin, but still quite potent. My employers sells fluorescently labeled cholera toxin to bind to a sugar moiety. I guess that makes it a lectin. More info here.

Only 200 Kg of Tritium on the planet
Whoa! its not all tritium.
According to these lecture notes from the University of Washington's Oceanographic Institute and estimate there was only 3.5 Kg of the stuff in existence before nuclear testing. Nowadays there is only about 200 Kg of the stuff on the planet. Remember tritium concentrations are not measured in PPM (Parts Per Million), PPB (Parts Per Billion) or even PPT (Parts Per Trillion) but rather TUs (Tritium Units) which is something like 10^-18 or something silly like that -

Re:Vaguely Ontopic
According to this site on metabolism and aquatic animals a moderately active blue shark needs to consume
.2 to .6% of its body mass in food per day. Larger animals tend to be more efficient in regards to metaboloism (with regards to sharks anyways) but lets assume the figure holds true. Also allow us to assume that this link on shark fossil identification is correct in its statements of the megalodon's size (up to 25 metric tons) so it would need to consume a whopping 50 to 150 pounds of food a day. given the size of its potential prey (other pages say sperm whale sized animals so call them 80,000 pounds) I don;t think the megalodon would have to eat very often to survive. Of course this is all completely conjecture based on insomnia and a reasonable set of google searches. -
I Love Console Apps!Hard to choose the greatest, but these are probably my top 10:
- Dev Todo is a wonderful outliner and task manager. Today I ported it to win32 using mingw to use at work (it pisses me off that windows dropped ANSI color support in their crappy CMD! I knew it was bad, but I still use it more than msys or cygwin because it is quicker on my slow box). Dev Todo stores everything in beautiful XML. I intend to make a filter for XSLT for my biweekly progress reports. My boss wants me to list things I've gotten done & what I plan to do & this great app can store all of that.
- Pine-I don't care if RMS doesn't consider it free. It is the best IMAP client. I do like Mulberry as well, though.
- GNU Screen-I mostly just detach/reattach. I'd like to learn to use it more.
- VIM-My editor. Again, need to learn it better.
- Lynx on windows and ELinks on Linux for browsing.
- I have aliased "fuck" to use cowsay to tell me to calm down. Great stress relief.
- GPG
- LaTeX. I hesitated to include this, but I use it on both linux and windows & it is technically interactive. I have started using it more than standard word processors (WordPerfect>OpenOffice>MS Word) and I want to use it instead of impress/powerpoint/whatever.
- OpenSSH because my box is so much better than the one I use at work
- NcFTP best ftp client I found, though I have been having much less need to use it.

the best console apps IMHO
1.- pine and pico (yes, I know the license issue)
2.- jdkchat (a telnet based chat system) -
For when you're not playing games...
After several attempts to live solely on the console, here are the best apps I've found:
Links: a superior web browser alternative to Lynx that formats things correctly on your screen.
Mutt and Pine: Two great email clients that allow you to work much more quickly than with any graphical client.
Nano: My favorite text editor. I refuse to feel guilty that it's easy to use!
Micq: a very nice ICQ client that works much better than the various AIM console clients that are out there.
Finally, last, and well yes, basically least, Seatris: This is the best -- the best! -- of all the console tetris games. It takes me back to wasting hours in the various UC Santa Cruz computer labs.
Um, Go Banana Slugs! Go Stevenson College! I think that takes care of this year's quota of school spirit. -

Akamai's DNS black magicAkamai uses (some would say ABuses) DNS in ways the rest of us (even global megacorps) wouldn't dare. Half of Akamai's magic is their 10000+ carefully-scattered servers, but the other half is their routing. Those servers are listed differently depending on where you ask from.
It's not like a092156fg.akamai.net is in Seattle and k1039665.akamai.net is in Saskatoon. Instead, all of *.akamai.net goes to whatever cluster is "closest" to the requesting IP (based on BGP, Colonel's Secret Recipe, etc)
So if Akamai's DNS gets screwed up, I would expect major weirdness. And as more sites join EdgeSuite (where you host your entire domain on Akamai's servers & DNS) the effect must magnify.Of course, I could be completely wrong. I'm not a routing god, just a guy who thinks Akamai is a cool hack.

Weber - Success of Open Source
This is an argument that Steven Weber makes in The Success of Open Source, which I reviewed recently. For more info, check out the list of reviews I've put together. While it's possible that the Economist thought of the idea on its own, I'm disappointed they didn't at least mention his previous work.

Re:as a scientist...
There is one great example of a journal on Artificial Intelligence that is peer-reviewed and available for free: JAIR. This is by the way a journal with a good reputation, so (being online != sleazy). I wonder why we don't see more example of this model, where the journal is available online, but you can always buy the paper version if you want to.

Delete attachments?Can the Mozilla e-mail client delete attachments on received e-mail yet? It seems like this misclassified bug has been ignored for many years. Anyone who deals with a large amount of e-mail would find it an absolute necessity. Even PINE can do it, along with almost every other client.
When you receive a message with an attachment, you should be able to right-click on the attachment in the attachment box and choose "Delete" from the popup menu. That would mark the attachment as deleted and if the message is moved or the folder is compressed, the attachment data itself would be removed, but the rest of the message would remain unmodified.

Autoclave... I'm late to the party here so this..
may be a dupe. It's not that hard to do a wipe of the HD.. I use a nice little utility on a floppy called Autoclave The only down-side is that it takes a while to do a high level over write of a large drive. If you're in a hurry, then take the sledge hammer approach...literally.

Re:Cleaning hard disks of passwords etc
When I had a disc that was failing under warranty, I used a bootable hard disk wiping utility as the final step before sending the drive back.
Autoclave is the one I used. It is quite nice, fits on a bootable floppy. I felt better sending my drive in for warranty replacement after using this program.

Re:Is it just me?For more info, start with this paper by Wallace Broecker. One good quote:
The fact that we are unable to provide satisfactory estimates of the probability that a conveyor shutdown will occur or of its consequences is certainly reason to be extremely prudent with regard to CO2 emissions. The record of events that transpired during the last glacial period sends us the clear warning that by adding greenhouse gases to the atmosphere, we are poking an angry beast (Fig. 5).

Representation
Who is the RIAA trying to represent? They say that they are representing the five major music labels. And in turn the music labels say that they are representing the artists themselves. But even the artists don't agree with the RIAA's methodologies.
"According to the study, 60 percent of those surveyed do not believe the RIAA's efforts to halt file sharing through lawsuits will benefit musicians and songwriters.
Additionally, 35 percent believe free downloading has helped their careers, 37 percent believe it has not had any effect and only 5 percent believe it has exclusively hurt their careers. Of those interviewed, 83 percent have provided free samples of their music online." -

Re:Crazy question - micro vs macro
I think Mac OS X is structured like a microkernel but everything's compiled and statically linked together for speed. With this setup, you can have your clean design but you still get rid of the context switches. That said, the design itself will impose some overhead (though the tradeoff may be worth it).
Another solution is to use a safe language to eliminate the need for address space separation and let the kernel JIT code when it's loaded. Compilation techniques for safe languages are getting better and better so performance is becoming less of an issue. One example is Brix, which runs everything in kernel space (even applications).
However, I don't know how you would deal with a misbehaving process in a shared address space (i.e. how would you write an OOM killer?). The Spin OS has a way of detecting badly-behaving code, but I think that dynamically-loadable code is restricted in what kind of functions it's allowed to perform.

Just keep your damn eye on the ball...
The feat of the no-hitter is indeed special, but you do truly have to be a sports fanatic to really be moved by the act. Ironically, the act of hitting a baseball is statistically one of the most difficult feats to perform (a 90 mph fastball crosses the plate approximately 0.4 seconds after it leaves the pitcher's hand (for those who need perspective, try this test Reaction Time) as the hitter must determine location (strike or ball), spin on the ball (curve, slider, fastball, splitter) and then swing a round bat to hit the round ball providing for a small margin of error for effective contact...not to mention that there are 9 guys on the field trying to catch the ball too...surprising that there aren't more perfect games. Thus, it is no surprise that those people that are considered "Hall of Famers" that have
.300 batting averages failed roughly 7 out of 10 times. Or was that software projects? -
Re:Bench marks? Reliability?Fedora is a distribution of Free software. They do not include packages that are not Free software. Pine is not Free since you can not redistribute modified versions without getting explicit permission from the University of Washington. Therefore, RedHat can not distribute pine in Fedora.
You may not care about using Free software, fine. That doesn't mean Fedora "sucks ass". Quite the contrary. You should give such distributions and their users (Debian, Fedora) some respect, since they're sacrificing their own short-term convenience for everybody's (including your own) long-term prosperity.
