At least in south-east asia I regretted bringing my laptop: Either you have an internet cafe or you have no power and internet connection at all. Knoppix or U3 or something on a well protected USB flash drive should be your best friend that doesn't weight much nor takes a lot of space in your backpack. Get a big one (e.g. 4 GB) and chose a decent resolution for your digital camera and you are ready to take more pictures than your relatives/friends would like you to show them. Consider renting a virtual (or real) server and using NX.
And remember: Once inside the namib deserts, be sure to forget about your tech-oriented life, go outside and enjoy the sun!
Password and PINs are fine and will be fair enough for the future. After all, for brute cracking a password you might need to enter it into some kind of device or internet connection which should force a 2 or 3 second breakt before your next try. No matter how fast your GPU is, you are limited to a maximum number of password per time period.
And concerning hash-stored passwords: First the bad boys should not be able to get them in the first place, and second we have a growing need for more complex (and secure) hashing algorithms and the likes.
I think with 14k, the e3 editor is quite as efficiently coded as possible while still easily usable. However, I know some AmigaOS apps that are smaller (and more usable). It's all a matter of what libraries get linked. C is a rather bloated language (although most people see it as a slim one nowadays). The "hello world" program in different languages can differ a lot. I remember testing AmigaE, C and AmigaBASIC (a Microsoft product). AmigaBASIC was around 50kb, C around 16kb (because I had to include stdout.h), E just 4kb. And you could get smaller using False, but who can program that? The entry level in Linux seems to be now 20kb, just to be able to do something at all. Using stuff like Java or Mono will surely increase the size of the executable.
Programming has changed: We are not forced to deal with limited resources, but we like to re-use prebuild libraries and modules quick 'n' easy. This is mostly no problem because computers are waiting most of the time for the user or the network or the disk or whatever. But when it really matters (like processing gigabytes of image data or vector data, compiling a large project etc.), programmers might consider doing this part in plain C or assembler (while still trying to keep portable).
AmigaOS (to throw in another pre-Win95 system that support longer than 8.3-filenames) was case insensitive, too. In addition it used its Locales feature to match Files like "WÜRMER" and "würmer" or "école" and "ÉCOLE". Once I knew the Linux way of case sensitivity, I must admit that the Linux solution is the best, since you cannot possibly sort out all strange German, French, Icelandic,... whatever letters.
In unrelated thoughs, a problem with different filesystems is that it's hard to preserve the correct spelling of those Umlauts or accends. WÜRMER.EXE on VFAT easily translates to W?RMER.EXE on my ext3 Linux system. Ideas anyone?
I don't really know if this accounts as non-root-access, but my company is using Windows XP boxes with a central server that holds our homedirs and updates the boxes with new/changes usernames/passwords and home directory files. (Is this LDAP? I don't know...)
So you can login with your passwort and you get only access to Windows shares (general shares and your personal homedir).
Anyway, while Windows Explorer and other "ordinary" Windows applications gave me a feeling of being locked out of the drive C:, cmd.exe told me otherwise: I can read and write all files on this computer, except other users' data in their respective home dirs which have proper attributes set (the box has a local and a network copy of the homedir and sync's them).
So... what is the point of hiding some drive letters but letting them be accessible through ordinary file I/O? Any virus or worm that doesn't care about if it should have access to C: or not will simply install itself anyway and continue to spread or kill the system or whatever.
Only changing file permissions (and obeying to them on OS level) would do the trick.
This is the second time, I see security holes like that. The first time, I encountered this strange concept of security on a WYSE terminal. While "Run a command" (and thus direct access to cmd.exe) was disabled, too, a cmd.exe-copy on my usb stick did the trick. (I suppose the WYSE thingy can automatically reinstall a clean Windows image, but still it is terrible approach of trying to be secure).
On the other hand, all my "official" software, like HP scanner drivers, fail to install themselves when I'm logged in but require "admin" access; I have no clue why!?!
I hate to admit that the Nokia phones seemed to be the stablest ones: no hangups, excellent battery. But rumors out there say that there are plenty of SMS and MMS exploits out there in the wild for Nokia. And I don't like the menu system.
Both Siemens M35i and Motorola V220 tend to lock up and lose 80% of their battery capacity after about 1.5 years.
The antenna sensitivity seemed to be equal to all phones. But sometimes the callee complained that my voice was low when I used the Motorola V220.
Now I'm waiting for a vim-plugin for Firefox and Opera, just like the Konqueror guys did it. So I can finally spellcheck and syntaxcheck my slashdot comments...;-)
The participants of this trial were all quite normal people: most of them Windooze users, one a Mac user. Nonetheless, this is the important userbase when it comes to phishing. (Or have you ever seen a linux phreak, living in mom's basement, who has something worth stealing in his bank account?)
Well, I personally (using Opera on Linux, designing and programming small websites and having done a phishing site for educational purposes once) fell for the bank of the vvest-spoof. I explicitely looked at the location bar and didn't see the vv. Needless to say that the rest of the spoof (the html part) was just superb.
The article states that they are running Solaris 8, upgrading to Solaris 10 now.
Well... they are running rockets and stuff, I'm only running my desktop with a Linux kernel, and it goes down sometimes... but the typical aircraft goes down more often.
A true (X)HTML freak will probably use a sophisticated text editor (like EditPad for Windows, nedit, bluefish or even emacs for Linux...), but for beginners a tools like Dreamweaver or Mozilla Composer or its next version nvu might be a good place to start. With NVU / Mozilla Composer, if you need something special in your source, you can switch to source-edit-mode and change or insert it.
A big disadvantage of many hight-level tools is their inability to cope with PHP. (By the way, the parent is right to say that PHP is a much better beginner's choice, since it is not as cryptic in syntax.)
On the client's side, you might find javascript useful. With a HTML layout tool, PHP and javascript, you can probably do most pages.
I remember vividly the times when we used to say "Eight Megabytes And Constant Swapping".
Now, with a bit more than 8 MB RAM at my hands, this is the past. But still there is a certain difference in size when you compare "e3" or even the full graphical editor "nedit" to emacs or vim.
I wonder where all the code goes...

Unfortunately, the article is a bit slim on details what they gain by using a "real" neural network. "Real" as in: you can touch it and it costs you a hell load of equiptment to keep it alive and running.
Some several thousand cells can be easily simulated within a computer. Every modern washing machine has them. So what's the catch?
Perhaps they try to learn more about the differences of real systems and emulated ones. After all, there is still plenty of discussion concerning the right algorythm how to let the virtual cells interact. And, real brains have several areas that behave slightly different (like the hippocampus for memory, the limbic system for emotions, etc.).
It would be interesting to know more about that.
I had a similiar problem with how to write a nice GUI in Perl and have an application that can run over a network? I used a webserver and CGI.pm.
I don't know whether there are CGI.pm-like libraries for C++, though...
The movie is amazingly amazing! The quality is superbe. Not only do they have nice clothes and fancy computer stuff in the background, also the computer generated graphics are marvelous. (Except for the "alien" ships which seem to have a slightly worse 3D modell.)
Now: why do the "professionals" need so much time and money for something like this? For example, the European re-take of "Dune" was just hillarious, the dunes for example - and there were a lot of dunes in Dune:) - didn't look real at all.
My biggest problem was to know in advance what I'd buy. Most cards don't come with chipset specifications, and - like with webcams - vendors like to change chipsets between different versions.
So, I bought a Linksys Wireless-G USB, thinking it is a Prism2 chipset which is well supported and has RFMON. It turned out, version 4 has a Ralink chipset which seems not to work flawlessy with ndiswrapper.
Fortunately, these great guys at rt2x00.serialmonkey.com have native driver that supports RFMON and native linux wireless extensions (unlike linux-wlan-ng that is... mmhmm... different). So far the drivers are quite stable and I'm hoping they will improve the remaining glitches (like setting a new MAC address).
... this will again take us into a century of nonunderstanding and confusion. Today, there are still some big nations that refuse to use kilogramm, litre, meter or celsius and prefer pounds, gallons, inch and fahrenheit.
How many rockets or other devices have disappeared or crashed somewhere just because scientists from one of these strange nations were involved in doing the programming?
Remeber, you heard it hear first: The end of the world is near...
The olfactory system is one of the phylogenetically oldest brain regions and has interconnections to lots of other systems.
Think of relationships: The smell of the person you are talking to influences your behaviour and your view of this person.
Think about other behaviour: McDonald's wouldn't be so famous if their food wouldn't be so tasty. Perfumes are a big market.
Think about mind control: If you get someone to do what you want by manipulating his/her olfactory system (e.g. through pheromones), it'd be nice, wouldn't it? Every/.er could have a girlfriend.:)
But there seems to be a problem with supporting H323. Does anybody know about the current status of chan_h323 for FreeBSD? (I mean, more than "doesn't work"?)
I put my 3-NIC-486/100Mhz-FreeBSD-Box into trash and moved on to the new shiny world of routers, that is a 1-NIC, WLAN-enabled German Telekom router.
Configuring the network is easy and straightforward, you can even configure for things like VoIP/p2p and it works pretty well. But the configuration procedure is HTML-only and does not allow any special setup (like using 192.168.1.2 instead of 192.168.1.1 because you have a stupid Windows Box with another LAN on your LAN; or putting through connection from 192.168.2.2 which is on a LAN behind your LAN but not masqueraded, so you can play StarCraft everywhere...).
And obviously, I cannot run any servers on this box (I used to run httpd).
And then I experienced connection problems. These happen mainly when asking the router to resolve a domain name. That is why I installed my old dnsd on my main computer, just before I was able to find/. and read this article.
In one word: If your system is small enough (buy a laptop), and has all NICs you need (buy a wifi-card), DO NOT REPLACE IT!
