I've been administering Citrix for many years, since it was Winframe 1.6 and was a modified version of NT 3.51.
Citrix just works. Another advantage is they support so many different client OS's. So, if you want to pay on the server side for Terminal Server CALs and Citrix Licenses, you get use a free OS, such as Linux and the Citrix client. If you already have Windows 2000 clients, you don't need to purchase TS CALS at all, its part of OS. Windows XP Pro also includes TS CALs.
List price for Citrix Metaframe Presentation server is $300 per concurrent user. You will also have to purchase Microsoft Terminal Server Client Access Licenses, which are less expensive, if I recall in the $10 per seat range.
I would be surprised that a library would have to pay full price for either the Windows or Citrix licenses.
As for server hardware, I was just at a Citrix user group where a Citrix SE claimed new dual AMD Operteron systems with 6 GB of RAM running Windows Server 2003 and Metaframe Presentation Server 3 could easily support 200 concurrent users. Last I checked, these boxes are not really that expensive in comparison to a room full of Dell boxes.
So, rough estimates of a dual HP Proliant DL145 with 2 Operteron 248 (2.2 Ghz) and 8 GB of RAM runs around $9000 with Windows Server 2003 installed.
The price of Citrix Software varies depending upon the number of concurrent users you expect, for example $9000 for 30 users at full list price.
The client works on quite junky computers, anything that can boot, has a good enough video card to display at 1024x768 or better, will run the Citrix client. They don't have to be fast, they just have to work.
No. If you watch him play, he gets answers wrong from time to time. In Millionaire, he'd be screwed, and bounce back to $16000 or $32000 for a wrong answer, and he'd be done. In Jeopardy! a wrong answer erases a bit of case, but only small amounts, and he does not get kicked off the show. Instead he get to continue. All he has to do is be better than the other two contestants, and know a bunch of trivia.
I've stopped watching TV. I own a PVR, and learned from it that the shows I watched, SCIFI, including Farscape, were compelling, but I was wasting tons of time watching it. Then the good shows were getting canceled for stupid reality TV shows.
I have since stopped paying for cable TV, and I live too far away to get over the air reception, so I just don't watch TV.
You know what? I just don't see the point. Until there are High Definition DVD's, I'm not buying any new TV technology. Period. I can wait. Plus, I spend more time with friends. I have had time to invite my neighbor over for dinner. I take my dog to the park. I talk to people more. And, I get more sleep. (Except tonight, cause I had too much coffee . ..)
My V120C was a good phone, until I broke the fricking antenna off. It has the words lousiest antenna design, which means it breaks off regularly from normal handling, and was NOT user replacable. Now I have a LG flip phone which sucks in terms of voice quality and reception, but beats a broken V120C.
Absolutely! I purchased a ReplayTV a while back, and was using it to watch reruns of shows that I liked, plus ST:Voyager and a bit of other SCIFI dreck. Anyway, I discovered that I would watch the shows I recorded, and NOTHING else. I found that I was no longer just vegging out and channel flipping.
Anyway, when the cable company finally discovered that I was not paying for TV, only for broadband service, they put a trap on the cable, and now I just have a ton more free time, and I get more sleep. What a concept.
So, instead of just feeling bad, powerless, screwed, angry about this mess, do something about it. I did. Go to ACLU Action page to send nice boiler plate text e-mail/faxes to each of the various decision makers in this process.

I was driving home in the south west suburb of Naperville, and saw the sky light up. It was cloudy, so I could not see where the light came from, but it was intensly bright.
I have to admit it made me think we'd been nuked. But then the light went away a few seconds later. I only heard a bit of a rumble over the roar of my 4 banger running at 3500 RPM at 80 mph. If I had not been going so fast, I would have stopped to take a look around, and soak up some good radiation if was a nuke.
All I can say is I'm glad that some local news made it past all the Iraq coverage.
I've had an incredible time since I have stopped paying SBC ~$90 a month for DSL and local telephone service. I switched to cable internet service and told SBC to take a walk. With my wireless phone, I pay around $40 for local and long distance, and yes, you guessed it. I have recieved no telemarketing calls. None. Zip. Its amazing. ..
You are so right. In my experience working as a SecurID admin, two factor authentication(something you have, something you know) is great. Especially when the end users tape their SecurID's to their laptops. We're back to just something you know, because a thief who swipes the laptop gets the securID too. Woo hooo.
--Peter Some users should be beaten with a clue stick.
Oooh, yeah and the PIII 1.13 Ghz chip worked sooooo well too! Whats that you say? Oh, Intel pulled it from the market? And the floating point performance is sooo good too.
Which motherboard did you buy? I have found processor has little to do with system stability. A good motherboard is the key to stability. So you got burned on your Athlon 500. The first release of any chip is a bad value in my opinion.
I have been evaluating IP Sec solutions for my job, and have found some interesting things along the way:
Please be aware that IPSec solutions do require automated rekeying of each connection, or even negotiate a new symetric key for each session. In fact it is a requirement to allow manual keying. Thus, if someone did discover your session key, they could impersonate you.
While anyone who would roll out IP Sec using manually distributed keys is taking a big risk of their key being discovered, you might be surprised that if you ever see someone demo IP Sec that they are actually using manual session keys.
WHY? 1. Its simpler, and 2. The IKE (internet key exchange) protocol is fairly new, and many vendor's IP Sec products don't work very well with other vendors certificate authorities.
Even if you decide to implement automated keying of the session, it is also theoretically possible to attack the Diffie-Helmann key exchange used to agree upon a session key using a man-in-the-middle attack.
Finally, if someone were to steal your digital certificate they could impersonate you again. Note: Some implementations of IP Sec client software DO NOT require a password to unlock the digital certificate. Yikes! Thus, if a user has your system, they are you to IP Sec.
The resulting aeroplane was the Tupelov TU-144, affectionatly known as "Concordski" - a 2/3 scale replica of a Concorde that couldn't fly . . . or at least not for very long:)
Actually the TU-144 could fly quite well. So well that NASA bought one or more of the planes!
It was taken out of service because a TU-144 crashed under odd circumstances at the Paris Airshow. Apparently a French Mirage was flying in the clouds when the TU-144 was doing its demonstration flight. This is a serious no no during said airshow because the risk of collision is very high is strictly against the rules of the airshow.
Anyway, the crash was most likely due to the Russian pilot reaction or over reaction to the presence of the french plane in its airspace. The story goes that the Russian nosed the plane down hard from a full throttle climb to avoid the Mirage, thus overstressing the airframe and causing structural failure. Everyone on board was killed and some innocent civilians too.
Neither French nor Russian governments would come to a satisfying conclusion of what happened. The above was gleaned by watching the same TLC show the previous poster noted.
Indeed! I attended Lyons Township in Western Springs, IL where the 9-10 graders attended a different campus that was 3/4 mile away from the one the 11-12 graders attended. Since kids who don't want to be in school could drop out after 10th grade, the last two years of school were SO much better, because the only ones who were there wanted to be there. I firmly believe other schools should look seriously at the physical separation of the freshman/sophmores from the juniors/seniors. This helps break up the cliques that we all know so much about.
Instead of being critical of high school, I have a generally positive view of it. I was lucky, I had some great teachers my last two years who really were interested in the students in class. On the other hand my first two years sucked. I think chance to start over again, in a new campus really made the experience better.
But by far the best part of high school was the music program, with two bands, an orchestra, and 4 choirs. I hear many people say that High school is not real life. Excepting music, they are right. Learing an instrument and singingn in a choir are two things that you can do after school, and can bring incredible amounts of enjoyment and satisfaction to ones life. Make music, its a wonderful thing to bring people together.
Yes, musicians can also incredibly competitive and nasty to each-other, too. But they all work towards a common goal; a good performance, tuning a chord, coming in on the right note, etc. These are all achievements that have immediate rewards for those who participate in the group.
Music is a foundation for Western culture, and is often overlooked by modern educators. Deemed too expensive or non-critical, it is often the first subject to be cut from the curriculum. I wonder how many slashdotters are musicians? I bet many are.
So stand up, attend your high school's music performances. Support your local school's general music class. DO something. Perhaps you can reach some of the ostracised and picked on.
In the windy city, tickets cost me $8.50 plus a $1.25 service charge for teleticket, 'cause you can almost never get a ticket at the box office for first run movies opening weekend. My wife and I went to see the matrix, which I loved and want to see again and paid:

Sometimes the government gets it right, albeit seldomly so. Remember, someone paid all those wonderfully creative people to create the Internet. Hmm. No one benefits from that, right? So, the government created a new market, and should probably get a chance to make tax money too, as frustrating as that may seem. The thing to do is to make certain that the revenue is reinvested in the network, not just put in the general coffer, similar to the unversal service money on the phone bill.
One might compare taxing of the internet to federal subsidies for tobacco farmers, which help big companies produce a great product cheaply (cigarettes) which gets taxed by federal, state and local governments.
In a few years, and class action suits start taking on ISP's for sending illegal porn via usenet to children (or some such nonsense), great sums of money will be had for the trail lawyers just like with tobacco industry.
I love over regulated industry. BTW, I work for the Federal Reserve Bank, the company that suggests the Know Your Customer policy in which private banks are to profile their customers transactions and report any strangeness to them as a way of preventing money laundering. Yes. Big brother is coming. . . This rule is still pending review, but I am ashamed to be a part of the organization that drafted it.
