In a situation like this, what's the best way to maintain all the student accounts? Integrate with one of the existing NIS+ domains (school servers are Suns), or are there better ways (maintaining a complete user database for 2 machines seems like a waste of time/effort)?
It's more local (Minneapolis area - but there's a few other states listed), but TCF seems to have a good online banking system (http://www.tcfexpress.com). I use it in Netscape for Linux, and seems to work fine with Java and Javascript turned off. I've never tried it from a windows machine, but I'm guessing it works fine there too.
I have to disagree... I have a Dell laptop (Inspiron 7500), and have had two problems with it - one was a bad charging circuit on the MB, and the other was a dying HD. For the motherboard problem, I called Dell at about 11PM on Tuesday, was on the phone for less than a half hour (including on hold - I said what I thought it was, tech asked 2 questions and agreed), had it picked up the next afternoon, and I picked it up from FedEx on my way home from work on Friday (they tried to deliver, but it was signature required). For the HD problem (which could have very well been caused by shock), I emailed them, got their standard reply about testing to be sure that it was the HD (involving taking out the CD drive and making sure it's not the CPU fan), told them it was intermittant and wasn't gonna sit there with the CD/Floppy bay open until it happened, and was told the new drive would be shipped next day. Neither problems were necessarily bad parts (the charging issue might have been a power surge, as the power at work had been wacky the last few days before it - all the server UPSs kept kicking in), and Dell replaced stuff no questions asked. I'd definitely buy their stuff again.
May have good bass, but if you look at the response they drop sharply at 16KHz, being down to basically nothing by 20KHz... Not exactly what one would expect from high-end headphones. They may work great if you're one of the people who just care about the bass, but they look like they'd be horible for stuff with a lot of high-end. And I'm not about to spend $300 to find out when the specs look this bad...
I've wondered what registering typo domains or other domains that aren't real but may be typed by someone looking for data, and doing a random redirect to somewhere else. Like I have at http://yafiygi.com/, except with a bunch of domains registered all bouncing off the server to random places...
What's in your robots.txt file? Things that change too often to be listed in search engine results, or the sorts of things that you don't want out there.
I've always taken the approach that robots.txt shouldn't contain anything that reveals semi-private sites on the server. Since it matches anything after the string listed, you don't really have to put even a whole directory name, just enough to make it not exclude things you might want listed...
Hmm... Two semesters ago the intro class I was in used Karel the Robot. Basically pascal to move a little robot with only a few commands around an environment consisting of walls and beepers. We had a GUI for it, but I'm guessing it's just an adaptation on your text mazes thing.
Most people took the example environment to use to code their robot to avoid obstacles. I'd start by making the environment as complex as possible and making it work there. I'd send my environments in with my program and once the prof decided to "test" programs in class in that environment (the real grading I'm guessing was done with the original). Only did a couple - some worked OK, others were pretty bad.
Whenever someone asked for advice on how to do a project I'd email them the environment and say "make it work on this"... hehe...
I also have a line with exceptions from an ftp machine that is configured similarily (I can't do passive to it). If you want to log you can do a -l on the last one. You can easily add a port 80 allow as well.
The only catch with this is if you portscan yourself you'll see everything as open (well, stuff that is open) even though nobody else can.
Hitting the enter button to send shows on your screen, but nothing is actually sent until you do the Ctrl+R ("Send Messages"). This is something that bugged me for a few hours til I finally figured it out. Have you tried that?
Ever try carrying around a chunk of dry ice and try to hand it to people? If you have a small enough piece and hold it right (always moving your hand a little), you can hold it with a cushion of CO2 between it and your hand. If you hand it to someone they'll usually hold their hand still to try to get a good look at it, resulting in them very quickly moving their hand away about 1/2 second later (either throwing it straight up or dropping it) and a terrified look on their face. Great fun...
Sounds good, but I'm wondering how you boot from hdc9. From what you show and say in your description you copy / to/root_shadow, and no mention of another partition with the kernel in it. That seems OK for a backup, but you also say you can pull out the hda drive and boot of hdc. Do you have another primary partion that's not mounted that allows you to do this? Or does the new LILO with support for >1024 cylinders do this, another boot manager, your BIOS, etc... You've got me wondering. I know people who are trying to get dual-boot and the only problem is the partition ends up being an extended at the end of the drive and they need a boot floppy.
I've had a solution like this for about 6 months now. XMMS (and Winamp, and I think a few people have used Real* stuff with it too) supports streaming via HTTP. I just set up an apache virtualhost pointing to my MP3 shares, and another pointing to index pages. To make the index pages I just created playlists of the files and threw them through a perl script that spit out the HTML complete with lists and such (I usually did one each time I had a bunch to add an customized them greatly for the task, but I could probably dig one out if it'd help). The links they created were basically the filename with characters escaped and the hostname prepended, and thrown after a m3u creating cgi (basically returned a text listing of whatever addresses were passed). This allowed me to have it request entire categories as long as the cgi could sort it.
The two virtualhosts were on the same machine, and could be setup on one if needed - I split them for easy of use, maintenance, and security (I set it up while at school, so I wanted the thing restricted so I didn't become the biggest bandwidth user on campus).
As for speed and such. When I click on a link the song is usually started before my finger is lifted off the mouse button (both at home on 100Mbps LAN and at school on the 10Mbps LAN). The response time is basically a factor of how fast the server is, how fast your browser can get the address to the player, and how fast the player can parse and request the address.
I have 2 sites currently hosted with digitalspace.net. My sites are small, so I like their 5MB for $2/mo plan. Some other cool things are you can have them add more domains to the root or a subdirectory for just the setup charge. Extra space is also only $.35/MB/mo. On my second site I have the DNS hosted elsewhere, which is something they don't mind at all (I specifically asked). You probably don't want to do that, so you could just use the service they provide.
Setup is pretty quick - within a couple days, and I haven't had any other problems. They have a 15MB and a 50MB plan (I think the 50MB is $15/mo or so). They also have a generous referral program ($2/referral), so it's nice to tell friends about. I haven't had any problems with speed accessing my site yet, so I highly recommend them. If you decide to use them and you're feeling extra generous, my email the account is on is mooneyj at tcfreenet dot org (appropriately decoded).
I have a Inspiron 7500 and just spent basically all day Thursday (except when I brought it to class - not bringing the monitor with) with dual monitor support. It gets addicting fast to be able to have multiple things open at the same time, and search on one monitor and have the results open in the other, etc. I was running both the LCD and external monitor at 1024x768 and didn't mess around with the other settings too much. I could have also hooked up a TV to the TV out simultaneously, but I didn't try that. It has a ATI Rage 8MB card, which is the best Dell (and I think everyone else - if even that) has, but I have to admit I haven't done any 3D games on it yet. It weighs quite a bit, but I take that as a required evil for the power it has.
The battery life is awesome too. With the battery that came with it I can go off to a 3hr class and come back with over 60% (sometimes closer to 70%) battery life left. I haven't tried to measure the full life yet (It's got LiIon batteries, so I keep it topped off). This battery life is taking notes in Staroffice and/or Mathematica with Rain running in the background, so you won't get the same battery life running Q3 or whatever, but for reports/web surfing it rocks!
I think that something that would be quite usefull to anyone who likes the text-only part of usenet and doesn't appreciate the spam/ignorant newbies type stuff (seems like most of/.) would be a newreader that is text only. Not the traditional text only, but also taking any article that contains <HTML> or other tags (I haven't bothered looking at what most HTML posts use) and just throws them out. Don't bother to cancel them, just not show them to the user. Anyone who wants to get a question answered by some of the people they see posting would realise eventually they can't post HTML. Spammers would probably not drop to text only because it seems most of them rely on graphics and stuff to get their point across. If someone wants to refer to something just post the text only URL (no HTML link) and people can use that. No unwanted banners, tracking, etc.
It appears their server is having problems temporarily (pings fine, but I can't even open a telnet connection to port 80). I have a mirror at my site: http://qux.net/l0pht/merger.html
Well, I don't think the FAA would have too much of a problem as they didn't seem to care about Lithium-Ion batteries much. Lithium-Ions are like timebombs... They become unstable if they are overchared, or if they get to low. They have processors in the batteries that cut off the terminals if the voltage falls below a limit, but there is the issue of self-discharge, which while lower than other types, still exists. After a few months a drained Li-Ion battery will go below it's safe level. There's a reason they tell you to keep them charged when you store them... Not to mention all the technology required in the chargers to measure the current and temperature just to keep them stable.
I want to get my CD on the network and NEVER touch it again. The big holdup is still the lack of widespread experience with the concept. Most people simply have never browsed a list of several thousand tracks from a few hundred CDs, clicked on one, and it started playing instantly. No walking up to the shelf, finding the CD, undusting it, ejecting and inserting the tray, waiting for the CD to spin up and track, etc etc. Once sufficient numbers of people experience this, the avalanche will start.
This is so true. I brought back a server to school with me where I have many songs available by streaming mp3. A large HD and a decent network makes the entire thing better than any other distribution system. My setup is one virtual host for the index, and one (currently) for the actual music. This allows me to add more hard drives and even servers if I max out the media server and keep the index in one place (All the work is done by Apache). Everyone who has looked at the system and tried listening that way loves it. Click to play the artist, album, or song and it's playing within about half a second. No trying to find someone with the CD or anything... I have my CDs in large (200 disc) CD Wallets so they are relatively easy to find, but this is so much easier. Once my entire collection is up and I add searching I can't imagine a better way.
remember those mac monitors that used to be popular with editors/publishers? They were taller than they were wide. Just a guess, but I bet that's the resolution they run at...
I'm actually hosted bu a reseller of them (http://www.bigbirds.com). They normally are pretty good, but I have had some outages lately (for about 1hr each time). They have a 99.5% uptime guarantee, but that has to be 3.something hours that they claim doesn't include maintenance. I also had another customer of theirs contact me a few days ago with one of my emails that he recieved in his account, and later forwarding headers from an outgoing message sent through his smtp server that the server says it came from my account. After contacting them about this it seems they claim there is no way to use my smtp server without using my pop3 accounts, and say there is no problem with the servers. I went and changed my passwords to appease them, but the problem is somewhere in the server. Other than this they seem to be a great value, and have a nice hosting setup. The response time from almost any place I've tried is very quick, and 4 DS-3s when they use less than 80% of three is nice.
I love those things. It takes almost no resources to do, I'm always online and away from my computer for much of that time while my mail programs automaticaly download new mail. I've found mail filters are usefull too. Another one is allcommunity.com (referrer quxnet or just go here). Luckily I don't get much other spam, but I don't mind if this is something that catches on.
