I'm sure I've been portscanned a couple times, but as far as I can find there have been no vulnerabilities found for my version of Cyrus. I found a CERT Vulnerability Note which talks about version 2.1.10, but I have 2.1.12 (from Debian unstable).
So, make sure there are no exploits for your IMAPd and hope for the best...:-)
Yup, I can vouch for this excellent setup. I use Postfix with Cyrus. Cyrus is an amazingly fast IMAP server, which is a good thing, seeing my mail server is a pokey 200 MHz machine.
On the client side, I use Mozilla mail whenever I'm behind my own desktop machine. When I'm logged in remotely, I'll use Pine (which supports IMAP) or through a browser with Squirrelmail, an excellent webmail client, which also talks IMAP. I also have my IMAP port open to the world, so I can use Mozilla mail when I'm at one of the computers at my university.
I have all my mailfolders the same everywhere, which is really nice. Now if there only was a nice way to share bookmarks and address books...
Well, I figure you'd need glasses with this special material too, to actually make out the individual buttons on the phone. Phones are already so small that they become difficult to use. The Nokia 8310 is already miniscule and doesn't actually weigh enough to hold comfortably in your hand. The buttons are pretty small. Pretty soon you will need a pen to peck at the buttons, cause your fingers are too large and you can't actually press one button without pressing others.
Anyway, I can see where this could be useful when you integrate a phone into your wristwatch or into your clothes or somesuch, but the regular hand held phones can't get much smaller without becoming cumbersome to use.
Hmm...ok, well, I suppose that you know more about it than I.:-) I thought I remembered reading about them using the IMEI number, which I thought was pretty clever, since changing SIM card wouldn't be effective.
They did this about a year ago here in the Netherlands. Phones listed as stolen were sent a barrage of SMS messages, basically every couple minutes, making the phone nearly unusable (incessant beeping of arriving messages, full inbox, etc)
In the GSM system, there is a SIM card which is linked to your phone number, subscription, etc. You put this card into your phone and use it. The phone itself has a unique identifyer as well, the IMEI number. It was these serial numbers which were used to identify stolen phones. So putting in a new SIM card won't work, because the phone will still identify itself to the network with its IMEI number.
I never saw any report on how sucessfull this was, however. I can imagine that in a lot of cases the owner didn't even know it was stolen (if they bought it second hand)...
Anyways, seems like a good way to harass people who use stolen phones.
We have the same here in the Netherlands (its called ChipKnip). You forgot to mention one of the more annoying problems: you don't know how much you are carrying. You can't look at your card and find out how much money is still on it.
Actually, this would be a cool application for that plastic flexible panel display thingy that was on/. a while back, have it embedded on your card. The only problem with this would be powersupply.
And yeah, the readers are very suceptible to dirt and other crap. Also the metallic contact points tend to get somewhat corroded after a while. I clean them with a pencil eraser. Works like a charm.
Yup, you notice this in other countries as well. I donate blood here in the Netherlands, and you're not elligible to donate blood if you've spent a total of 6 months or more in the UK, cause of all the mad cow disease, etc.
Actually, their news page is even more up to date. The zeitgeist is updated infrequently compared to the news page. Of course, the news page is biased, since it only gets its info from news sites which have been defined already.
Of course they could do something similar with weblogs.
The double S thing is a section symbol. I've never actually seen it used in a document anywhere; I can't remember how I got this particular knowledge, but here's an example of it.
Here in Holland many of the highways have these sensors in the road, that can tell traffic density. There are a number of websites that provide you with realtime traffic density data. See this picture for an example. This is a JPG which is recreated every 5 minutes or so.
OMG! This is my favorite SF book! I've read it many times and still every time I really enjoy reading it. There are some very spectacular scenes that can be done very well screen. I hope they do a good job of it.
If you haven't read it yet, do so.

The technology behind FreeNet is very cool, very well thought out, except for one thing: searching. You can't really search for arbitrary strings like most apps. They are working on it, but a good solution is yet to come out of it.
There are some indexing services, but they need to grow and get a user community behind them (like FileNexus and ShareReactor for eDonkey/Overnet)
If they got that going, it'd be interesting... but then you would still be restricted to searching in what was in the releases index... which would not reflect everything that is available.
The eDonkey people are not updating eDonkey anymore, because it was not meant to be scalable. They have started Overnet, a scalable version. This uses the same great features, file hashes, multiple source downloads, etc, but does not need central peer index servers.
FileNexus and ShareReactor work in Overnet too. They can take ed2k links and download them. These indexing services are really a very cool feature. No more wondering which file will probably be the one you are looking for and hoping for the best.
I run Overnet under `screen` on my linux server, which works beautifully. Download speeds vary a lot, but eDonkey/Overnet is generally a P2P app you start up, and then come back a week later to find a whole bunch of files downloaded.
Why wouldn't it work for KaZaa? It works just fine for Overnet/eDonkey. You have sites like ShareReactor, which do indexing for known good releases with their MD4 hashes. You click on a special ed2k:// link and it'll download just that file. No chance in hell of a bad copy sneaking in.
KaZaa is a much larger community than eDonkey. it worked for eDonkey, so if KaZaa gets it, I see it definately working.
Now if they would only release a Linux command line client...
This probably won't be happening for a while. First of all, there's the hardware problem. Which wire leads where? Then once you've got your connection to the hardware (well, wetware really), you still need to reverse engineer the protocols used. Granted, humans have become pretty good at reverse engineering the last couple years, but this will still be significantly hard. There's no documentation and no decompilers.
I'm all for it; I'll be first in line for a jack which will bypass regular senses and plug directly into my brain (yeah, okay... I've read too much William Gibson).
As for being proprietory or not... I see this tech being developed at a research center in a company, not at some university lab. This company is going to want to make money off of their research investments. So it probably won't be open/free in the beginning.
Yeah, I've often wished for this too. There was actually one time where I was looking for something in a room and I'd been doing stuff on the computer all day and I thought to myself, "hey, I'll just ctrl-f"... after which realizing that there was no such thing (yet). Kinda funny.
Actually, to all people who use metric (most of the world), this actually brings it more into perspective. 0 to 190 in 4 seconds is most impressive. It takes a skydiver in freefall at least 10 seconds to get to that speed.
So how is the stitching happening in Cyra's software? This is a nontrivial task, to reconstruct a surface from a set of data points. Or is this proprietory information?:-)
One of the coolest 3d surface reconstruction algorithms I've seen to date is the crust algorithm. With a clever combination of Voronoi cells and Delaunay triangulation it does a very very good job of recreating the surface. Very cool stuff!
Actually, if you have access to a place you can put a CGI script, you can install SugarPlum, a spam database poisoning script which will generate realistic looking but fake email address on a web page.
This is a lot less work than setting up hotmail accounts.

Yeah, those are really strong... What are they made of? They seem ceramic, not even metal. Neodymium?
I remember playing with neodymium magnets during physics class. Damn those things were strong. Will stick to anything remotely metal. Very cool.

Anyone know how many Gs this thing would produce?

Well... there's always base jumping. 520 feet would be enough, but you wouldn't want to be doing any freefalling from there, true... :-)
