way out of the loop. are you still running a 80386 arch?
yeah PCI-express has been the buzz word with Dell and HP for their new PCs. it looks promising.
another note, does anyone know the bandwidth of PC2100 DDR ram? or even PC2800 DDR ram? i'm wondering what the max bw is on DDR RAM vs the bw of the new PCI-express.
with a 2000 lumen system you could see it in almost any interior lighting setup. I recently evaluated a Toshiba MU-700 (or something close to that) and I setup a 1000-1200 lumen, Toshiba P5, system next to it. The 2000 lumen system looked incredible in comparison.
Then again the 2000 lumen system was $1649.00 compared to the 1K mark for the lesser.
Coppit, projectors bulbs last anywhere from 1000-3000 hours. They run at a high wattage and they're expensive to repair. The average bulb (thinking NEC, Dell, Infocus, Toshiba, ViewSonic) is from 180 - 400 dollars a piece.
So up front the investment is great but the downside is the replacement of the parts, bulbs, color wheel, ballast, etc.
I purchasing IT equipment and albeit I'm not looking it up right now BUT I'm always turned off by the LCD TVs low native resolution when it comes to computer displays.
Most of them only have an 800 x 600 resolution or commonly 1024 x 768. On a 23" LCD screen (1024 x 768) it's going to look decent but not as great as it can be.
I'm not sure why the resolutions are so low but optimally I would say you should go for 1600 x 1200 resolution. These are out there but they're still up there in price. I would say wait a year or two to make the investment.
I predict too that 15" LCDs will go bye bye within 18-24 months and only be made for notebooks. We'll still see 13" - 17" notebooks but the core will be 15" and then the primary/standard LCD monitor will be 17". At this point the 21" - 23" market are going to drop along with the 17". Where is evidence of this? 15" LCD monitors are going up in price (remember I'm talking about large volume pricing here) and closing the margin between 15" and 17" LCD monitors so that the transition won't be so hard for the corporate customers.
1. Buy up 1st tier suppliers for radio mfgs. 2. Implement "secret" feature to disable these with a simple RF frz. 2.5... 3. Wait 5 years. 4. Enjoy the ability to disable almost anyone's car radio and equipment. 5.... 6. Build a device that disables your disabling system. Sell to youngsters. 7. PROFIT! 8. See secret item 2.5 where you built in a second disabling device. 9. Enjoy your power.
well my understanding of proxies, VPNs, and ports overall is somewhat limit. I do have some exposure to these at my work (indirectly).
at my office we can't utilize any programs that access the internet through certain ports. my understanding is that they watch the traffic and when they see a certain port range boom they block it assuming it's P2P or IM client or something new. so what i'm assuming is that indeed only port 1080 and 80 are open but again your right I don't know too much about the primary web viewing ports.
please feel free to elaborate though. i'd like to understand more. thx.
This is a good point. Frankly make them sign a contract or a LOI stating that if they do anything illegal that they have to indemify the university of any illegal actions and take full recourse for the aforementioned.
But if 90% of their traffic is P2P why not make it all internal traffic thus eliminating bandwidth costs? If there is a way to do this for instance block the ports that P2P programs use, hell block all the ports except 80 and then setup a VPN client with all ports open but restrict traffic to being only internal. Then the bandwidth load is reduced by 90% and the traffic (which would probably cut down) might come down by as much as 60-70%.
If new items need to be introduced to the P2P networks on the campus then the students should have to go out and use their own, their parents or some cafes' then they can bring it back into the closed school network.
currently you can use HTTP Tunnell and it will access whatever ports your using through port 80. but to a proxy server it shows up going to HTTP Tunnells server thus showing someone your cards. soon they're just blacklist the server/IP and then you have nothing.
I'm sure that there are enough smart people out there that could rewrite some software to emulate other ports. setup the software so that it runs whatever program at it's port (like 6989) and then have the software make the computer think that it's port 80.
Also, what about a VPN? isn't that another way around it?
This all reminds me of a recent John Grisham novel, King of Torts, where a lawyer sues someone product liability and the case goes through in months. The lawyer wins but there are damages beyond what the case. So another lawyer who's pissed off sues the lawyer because the law has already judged the plantiff and the defendant.
I understand that the context is different but perhaps something similar might happen. Instead of them suing the RIAA they could sue the RIAAs lawyers. That would be interesting...
But you get something like 215 units per 802.11 bridge. Which would equate to longer range and a less units.
What is the speed rating of BT? If you went G on the wifi side you can get 54Mbps but what about BT? I'm sure even 11Mbps with 802.11b is enough for any web based application though.
The Recon unit is nice but it's too expensive. I think that you should go cheap like Dell Axim or Toshiba e800 and that you should "ruggedize" it yourself.
Think about the cost savings benefit and the replaceability. Depending on negotiations I'm sure that you could get them dirt cheap (considering their list price, the winning company also gets free or co-op marketing) and have them throw in a warranty that covers dropping, etc. Then make sure the warranty also covers modifications, such as silicon, epoxy, etc so that you can seal the puppy up. Put a Fellowes protective cover on the screen after that and your ready to go.
The whole purchasing aspect, warranty, price, aren't far fetched that is the easy part. Making sure that they're sealed would be the part someone would have to explore.
The range of Bluetooth is only 10 meters compared to approximately 100 meters for a wireless bridge.
Furthermore, I understand that there are a number of things that you can do to extend the range of 802.11 frequencies and bridges but I'm not familar with any to extend Bluetooth.
First off, I might be repeating what others have said here but there are a few things to consider, price, prob of damage/theft, ways to track and prevent theft, and programming capabilities.
Here is what I'd say, go with a PDA (PocketPC or Palm) but you'd have to develop some sort of automatic wireless backup software that runs the backup of the softare and data before the battery dies, like at a certain point, 10% of battery left. Otherwise you'd be tired out by constantly reviving and restoring data to the PDAs. This is one of the most annoying featurs of PDAs. Tablets are nice but they're too costly and they're too large, apart from that ALL tablets use the electronic pen. ----The reason this is is b/c if you were trying to write a nice note on a 13" screen your hand would constantly leave a mark in the note you are writing.---- Apart from that Tablet's still only get about the same amount of battery life as a PDA. Furthermore your looking at a harddrive faluire (possibly) each time you have one of the drunk morons (sorry to be an insensitive clod) drop the tablet. A PDA has a flash HD, of sorts, that doesn't lose data when it's dropped. PDAs also usually come with 802.11b integrated (if you go with the PocketPC or Tungsten Palm) which is a bonus.
Apart from price and prob of damage, look at tracking. You'll need to setup some sort of tracking server that would log usage of the units, software to check them out/in, some sort of way to locate them and keep them from leaving the building. I'm not thinking GPS here b/c of that's what all the ACs are going to shout out (clod again) but I'm thinking EAS tags and/or RFID tags. RFID tags can be scanned to give you a general proximity plus an EAS tag with a gate can keep the unit from leaving. Perhaps just an EAS tag would work fine without an RFID.
Lsatly, think about the software that you'll need, how are you going to do all the things that you'll need to do? Someone think of what he/she is going to need. I'm thinking server side software to authenticate, logging of traffic, load balancing, proxy server, POS software, anything else?
Tell MGMT that they're nuts. An easier solution would be to integrate the units right into the seats. Put something sturdy right into the seat in front of the person and tether it. Only put it in classy sections, like bottom, suites, etc. I understand this means a larger investment up front and possibly less return vs number of units but it seems like it would be less of a hassle.
What about hardware? I'm talking about load balancers, servers, and phone sets? Let's suppose you roll something like this out to a community, what would they have to have to support it? Probably a server with a 1Gb backbone right? Something to handle all of the traffic too. Then they'll need hardware for the phone replacement. Or it could be offered as a notebook/PDA based software that you use to make your calls.
I've been thinking about this same thing just recently. From what I understand http://ask.slashdot.org/article.pl?sid=04/04/13/20 43202&mode=nested&tid=126&tid=137&tid= 215 that VoIP still isn't the most reliable thing in the world. There are a few things from a business stand point that will keep WVoIP from overtaking the mobile market, although this is perfectly tempting.
Here are a few of the reasons:
The number of flaws and hacks that are readily available for switches, routers, and hubs and the fact that the OSes that run these appliances are too vunereable (think M$).
The fact that the system isn't proprietary. I understand that there are ways to make a wireless network prop by MAC translation, etc.
Handsets, currently there aren't any handsets available nor anybody in the market who wants to make them
Well, these are just a few thoughts. I know that there are many other insights as to what might make this industry grow.
Currently, to me, it seems like a lot of the open public widespread wireless networks tend to be international countries (not America) and they tend to be home grown by some geeks.
Represent a business model that would cost billions to setup and would still have to have willing hardware developers to make it happen and let me know what capital investors are interested.
After reading the article it's nice to know that Yoda lives near me but he has some side effects. He has to be near the other mouse to keep from freezing and he's a third smaller than the others.
I imagine that they'll tweak the gene modification so that the mouse isn't small and doesn't freeze to death. But when will this be something useful for us? Too far into the future that's when.
If the driver is all ready speeding, what is going to stop him/her from blowing through the red light. Seems like a possibly dangerous way to deal with the problem.
I imagine that they would make both directions red for x amount of seconds to make sure that no one was hit.
This, of course, would mean that drivers would have to be more educated and SoS around the country is still having trouble with that.
This would be nice, if we could make it similar to how the pisser in the pool turns purple. The car becomes some obnoxious color so that we can honk and flash (fingers).
This is exactly what would happen but if the individual setup a company and took a long long time implement the use of the materials then they could effectively avert the pollution.
It's about a sensor that when your speeding towards a light at 5 MPH or more above the speed limit it changes the light to red and makes you wait. Which is supposed to allow you time to cool off.
This is a bit off topic b/c we are talking about internal car technology and drowiness but I think it's interesting none the less.

Which do you disable?
