I travelled through Cambodia last November - the prices there may range from under $1 to over $5 for tourists, depending on where you go - fancy hotels are of course the most expensive. In Ratanakiri, a remote province, there was only one place that offered net access for $5/15 minutes. So without knowing exactly how those prices are compiled (average in capital city? average throughout country?), the accuracy is difficult to judge - more so since your poorer locals aren't going to go to the fancy hotel for net access.
This map is also really decieving b/c many net cafes i've been to have different rates: one for foreigners, one for locals, and one for friends. The same place in Lima, Peru will charge me differently depending on how well i speak spanish when i walk in (and how i'm dressed, etc). Thus, this map is trying to compare two numbers which don't necessarily directly relate to each other.
On a different note, i hated Thailand, but i only spent a couple days in Bangkok. I think the first day there i met every con artist in the city.
I haven't tried changing a partition to use dirindex myself, but the fedora (release 1 and on) tune2fs manpage lists it as something that can be changed: tune2fs -O dir_index [device]
These tests were run on a Dell 1750, dual 2.4 Xeon, 2GB ram, 3 35GB drives in RAID5 configuration (hardware RAID), each test done in the same 10GB partition, and the results shown are the average of 5 bonnie++ runs (with the exception of jfs - it hung after the 3rd run and yes i opened a bug ticket with fedora about it) with ext2 being 100% and everything else shown in relation to its performance.
I'd still rather have a whole tcp stack implemented on top of portknocking. Two machines, no open ports, yet still speaking tcp to eachother. April fool's is coming up. Anyone? Anyone?
Paycheck, I have it in a 1977 Del Rey Compilation (the cover is a multi-sphered space structure, i think, it's rather worn). It's typical Dick, listed as (c)1953 Greenleaf Publications, Inc, for June 1953 Imagination, and the story reads like many other of his stories from that time period. It's witty, innovative, and, to today's audience, 100% cheesy.
For reference to other movies,
Minority Report was published in 1954,
We Can Remember It For You Wholesale (Total Recall) published 1965,
Do Androids Dream Of Electric Sheep (Blade Runner) published 1968,
Second Variety (Screamers) published 1953,
Impostor published 1953.
Personally i really enjoy the cheesy wit that most of his short stories are innundated with, and am looking forward to Paycheck, despite my apprehension with Ben Affleck (god, that jaw!).
If you want to read PKD, i think his best stuff was from the late 60's early 70's. The short stories from the 50's and early 60's feel like quick thoughts that PKD was shooting out on the fly, stuff he was thinking through on his way to later full thoughts. His stories after the mid-70's (there aren't many) are too ethereal and "out there", almost to the point of being unreadable. And for a very different sort of work by PKD, read Confessions of a Crap Artist.
Disclaimer: I've read a substantial amount of PKD, but as he was such a prolific writer, i've read nowhere near all or even most of his work.
As for John Woo, I've enjoyed his style in Face/Off and Broken Arrow, and in both he had to overcome the Actor Wraith John Travolta (lately seems to act so bad that he sucks the acting ability out of others). Hell, Hard Target even had some style thanks to John Woo, and it's a Van Damme movie. Presumably he'll be able to work through Ben's jaw as well.
It's too bad the rumours of John Woo doing a TMNT movie aren't true.
One more option: you can disconnect the reset switch.
Take a hint from fire alarms and hook up the power switch to a squirt gun full of a staining dye. Now you know who to chase around with the rolled up newspaper.
No, Copan is in Honduras and Tikal (as seen in Star Wars A New Hope) is in Guatemala. There are a bunch of other Mayan sites throughout those countries but i can't remember any other names; Copan and Tikal are two of the most famous Mayan sites.
Wonder where 7 bits comes from. 10 or 5 --that I'd understand. 7, perhaps someone who'd been in a terrible accident?!
Perhaps from their cosmology. Do a google search for chakana, the name of a main symbol adopted by the Incans. The results will explain a lot about their cosmology.
7 may come from the 4 directions plus the 3 worlds.
honeyd mentions this sort of use. So does uml. also look into bait and switch honeypots, they mention using virtual machines as the honeypots (at least they did in a presentation i saw).
Once Solaris 10 comes out, its zomes might be able to provide a better infrastructure for what the original article was talking about, but the last presentation i saw on zones was unsure about the monitoring capabilities to be built in.
The performance boost this article mentions sounds nice, but i don't understand what else they accomplished that a tcpdump on the host machine couldn't do.
Secrets and Lies, by Bruce Schneier, will give you a good overview of computer security (other books exist for this general overview too,but ihappen to have just finished this one). From there you can delve into more in depth overviews or specific topics.
More in depth overviews:
any CISSP/GISC/Security+ certification book (plus, after reading it go get certified!).
Topic Specific:
Firewalls (contrary to what others may tell you, there is more to security than firewalls). Some good books: the O'Reilly Firewall book, Building Linux and OpenBSD Firewalls (a bit dated but still on topic).
Do a search for all O'Reilly books with 'security' in the title/description, flip through it, decide if it suits your need (e.g. Web Security, Computer Security Basics, OpenSSL security, etc).
Learning the topic *really*well* is very important - e.g. really understand TCP/IP (something beyond "i plug in the cable, run dhclient, and i get internet!") andlook at it with an eye for security. Same goes for web server, general sysadmin tasks, programming, etc.
Remember: security is a process. and a moving target. and impossible to fix %100 but try anyways.
Experience is essential too. Get yourself an experimental network and try attacks, network sniffing, securing, MiTM'ing, getting around firewalls, DoS'ing, snort'ing, arpspoofing, etc. Once you've run some attacks then you'll have a working idea of what is going on and will hopefully be able to see when a line of thought would lead you in the same direction in setting up your network. Plus it helps to know you could set up a quick demo to show how easy it is to sniff someone's password, even on a switched network.
Become a keen observer of people. The users are your number one enemy in terms of security. They'll give their password away to anyone, try to thwart your attempts to secure the network, print out and take confidential docs to the cafe, etc. Not on purpose, but b/c their priority is getting work done. Understand them so as to best work with them.
And there's a whole lot more, but most importantly remember that security requires a very robust approach. Not just a firewall, not just encrypting everything, not just checking all code, but a well thought out approach that is followed, revised, updated, explained to all employees, etc etc
According to dns, zombo.com has only been around since 1999 but jodi.org has been there since 1995, and i remember first hearing about it in 1996. Also check out http://www.dextro.org/
As for html being used in art, that's what the second show at http://art.by.arena.ne.jp/ (1995) was all about. Plus some art shows have featured websites as part of their exhibitions for a while - nothing major that i can think of, but groups like http://entity.ummu.umich.edu/. Then there were (are? can't find link) the minimalist competitions - designing in under 5k pages - and the like. If you want pictures made from html then maybe my http://www.blackant.net/code/oth/img-html-src.html will suffice.
I'm sure i'm missing plenty of other sites and competitions but it's only 7am in my TZ.
The problem is that for every gallon of seawater that passes through, most of the plankton, algae and other tiny sea creatures who live in that gallon don't survive the amazing journey.
Big deal - put a restaurant next to the power plant and serve boiled plankton and algae as a specialty.
Once humans start exclusively eating plankton, we won't even need all those other pesky animals like steer or pigs or lamb - we'll be at the top of a very short food chain. That should help eliminate a lot of other worries too, like decreasing farmland, soil erosion, mad cow disease, etc.
my mom has a Win98 P-100 from a few years ago. it works fine, never had a problem (aside from needing reboot every few days). i do tech support for it, which consists of me calling her and saying, "that thing still works?" and her telling me it does, no problems, thanks. every now and then i help add something to it, like another hd or a scanner, still no problems.
usually the only problems i have with hardware are from really old components (> ten years), really cheap components, or a computer i didn't test enough before turning loose.
a couple more bucks for name-brand materials and a couple hours of burn-in tests really helps. especially those tests: make sure the components are good before you start using them. i've learned to regret ignoring even the slightest anomaly.
but a good local college that has computer courses will probably have someone who knows their shit teaching, rather than just some schmuck that took the course last year.
i work at washtenaw community college in AA, MI. the classes vary from semester to semester, depending on who teaches what when. sometimes it is someone who just read a book a month before teaching the class, sometimes it is someone with 20+ yrs experience who just loves to teach.
your best bet is to have a friend who works at a community college and ask that person about the classes and instructors you are considering. a counselor at the college might help too, but they cant as straight-forwardly tell you that so-and-so sucks. i've helped my friends like this, advising them on what instructors to avoid and why, which ones are known to be good, which programs have been developed by people who have their shit together and which are wraught with politics and headed for disaster.
where i work, (www.wccnet.edu) we have some decent equipment and are really inexpensive for in-state. our computer classes teach a lot of hands-on knowledge and sometimes you will get an instructor who really can help with their years of experience, not only help in teaching but also in the hookups/human networking.
and i dare say we have one of the best photo programs in the country (definitely in terms of equipment); if you are starting to learn photography it would be worth your time to move here and take some classes, but be sure to ask someone who went through the program about what instructors to avoid and which ones are the truly greats.
Born in Waterloo, Iowa on April 2, 2245; Benjamin Halley is a non-descript red-shirt who, in the classic tradition, is vaporized early in the script. Like all such red-shirts, the 'X' at the end of his serial number indicates that he is surely doomed.
Even better, if aliens come and destroy all the major cities, there's no way in hell they're going to bother with Omaha, NE.
Omaha, NE is real close to where SAC operated back in the day. what's the name of the air force base there? i belive Bush flew there during 9/11.
Had the Cold War gone hot, Omaha would have been well within the affected area of a number of nukes. Then again, Washignton would have been, too. Better to keep docs in Your Big City, and then in some Nowheresville.
if you ever drive through NE, check out the SAC museum, off of I-80 in between Omaha and Lincoln (my photos of the musuem). it has a number of beautiful aircraft as well as a lot of historical information. Not nearly as large as the Dayton Museum (my photos), but still worth the stop.
This would be ideal to store an OS, even for a server, and have the HDs configured to copy the os back to the card and reboot in case it fails to boot from the card for some reason...
kind of similar to RAID 1 with ramdisk/hd. after the mirror is rebuilt, take the hd out of the picture. re-insert hd and resync periodically for backups. won't decrease your boottime and is really esoteric.
Not only is that not at all what he is talking about but there has long been VRML which is pretty much the same thing you are talking about.
i wrote this many years ago, it is why i originally learned perl- HTML to VRML converter
dont know how well/poorly it works, havent used it in ages and have gone through many perl changes since then.
Why doesn't SETI@Home check each WU as it's submitted and say "Gee, here's hundreds of people from the same team submitting the same WU with the same result within minutes of each other. Seems awful suspicious!"
they should make note of each work unit that goes out, and make sure it comes back from the same account. if the same account returns the same unit more than X times, it would be abusive but wouldnt cause any harm nor be added to the totals for that account.
i suppose you could then cheat by getting a shitload of WU's (a few million?) and comparing to the millions of WU's your friend got, split the same ones and send them both in once processed. if the total pool of WU's is large enough, this should be rather impratical or should at least be easily spotted.
SFTP is not technically a filesystem, but can be used as one by Linux with LUFS [sourceforge.net]. I think a LUFS-equivalent for [Open]BSD would be a huge win
if NetBSD's mount_portal was ported to OpenBSD then i think it would be simple. right now OpenBSD (and FreeBSD) uses an older mount_portal which isn't as robust as NetBSD's.
anyone know the linux equivalent of mount_portal?

In "The Way Things Work" (1988) David Macaulay also illustrates logic gates as plumbing in a building. It's on page 333 of the original book; the newer version even has an interesting rant about Bill Gates.
i always liked old school water clocks.
i seem to recall something about logic gates or some sort of logic being built out of matchboxes and beans. it played tictactoe, deciding the best move by plopping out a bean of a certain colour? i can remember neither the details nor the source.
