Lasers can be created by several things, most commonly electricity passing through certain types of gasses. The primary problem with this design is power - we don't have a portable nuclear power pack yet, and I sure don't want to carry one around and get shot at.
Since you can also get laser power from chemical sources, is it possible to make laser "bullets" that are basically chemical sources with an electronic trigger? Firing them from the gun passes a small trigger charge into the bullet, which lases (is that even a word?) the chemicals inside the bullet all at once - ejecting a large light pulse out the end of the gun at one time.
The bullet is then ejected and a new one from the magazine is loaded into the chamber.
Does anyone know how much power you can get in a short chemical laser burst like this? How large would the bullet have to be to have adequate power?
I install a second copy of Windows on every server box I install. I put it in a C:\CLEANWIN directory. It has no software loaded, and the minimal amount of accessories on it. If the primary windows system gets compromised, I can boot to the CLEANWIN directory and recover the other OS.
Well, if you read the pricing page, you'll see that you can get AOL for as little as $4.95 per month. I've switched several people over to cable, and dropped their AOL charges down to this small plan. They keep their old @aol.com email address, and get to it using the AOL client and TCP/IP over the broadband connection.
Oracle will use the index Table(A,B) to locate all A where A=Y, then scan through those rows for B=X. It will not use the full index like you've said. If you want to use the full index, you either need to specify A=Y before B=X, or use two separate indexes Table(A) and Table(B) which can be bitmap-joined to produce the given result set.
You're right, Oracle should optimize the where clause to use composite indexes, but Oracle usually recommends not using ANY composite indexes in favor of bitmap-joined indexes. Oracle will not use multiple composite indexes on a single table.
I worked with some underground fiber (owned by the city water department) a couple of years ago. It was running a low-speed serial link between a PLC and a computer. My task was to run ethernet over this link (at 10MB or 100MB speeds). The problem was the fiber was a little older and was a larger size. We BARELY got 10MB to run over it. 100MB was impossible without VERY expensive equipment.
If you'd post some specs on fiber size, termination, and distance, we could give you better answers than "just a couple of routers with fiber ports".
My point was NOT to simply guess on the time, but to give an example of how you take a project estimate and double it.
You're right that the poster doesn't supply NEARLY enough information, but on the other hand, I think that 7 months is about right given the sketchy details provided.
I'm currently working on a project to build a customer relationship database that is replicated to salespeoples' computers. The spec was for 6 weeks of development time, and I'm going to have it done inside of 5 weeks.
Good software doesn't have to take years to build, or piles of money. You just need to choose the right tools for the job, plan a good specification about what the application needs to do, and IMPLEMENT the frigging thing. A lot of people now-a-days try to over-architect the app before any code gets written. I believe that properly designed code can be refactored as it's being built, getting the product out the door quickly, and implementing new (changed/additional/etc) features in later versions.
Have you ever read the license agreement from Borland?
(Trimmed for brevity)
"Section 2.1 - Grant of License. Borland grants to you a personal, nonexclusive, nontransferable and limited license to use the Product. You may install the Product on a reasonable number of machines provided that the Named User is the only individual permitted to use the Product."
Seems rather reasonable to me. I have Delphi 7 installed on my desktop at the office and my laptop at home. It's all perfectly legal and I can work on projects when I'm at home or on the road.
This is a very "common-sense" based license. Don't try to screw over Borland and they won't try to screw you over.

I started with a new company in August and the first thing I was tasked to do was build a bunch of dynamic-content web pages for a new web site.
What was the first thing I did? Scrap IIS and VBScript in favor of Apache2 and PHP. PHP runs WONDERFULLY as an Apache2 module, and I have had literally ZERO problems with this install on Windows 2000.
Running Apache has been a dream compared to managing IIS. We use Oracle for our back-end database, and PHP's OCI8 module has performed flawlessly. So far this solution has been installed on 3 different web servers, and I have yet to see an "unexplained crash". I get errors in the logs because of bad code in some of the pages or a missing file here or there, but Apache2 just keeps on working and PHP just keeps on serving pages.
I would guess that you're running into a scalability problem with IIS and spawned processes. Last time I used IIS, it seemed like it wouldn't release process or object handles until the service was restarted. After a while, the system would literally run out of new process handles to give out, and new processes wouldn't start up. Restarting IIS always seemed to cure the problem, but what a PITA. That's when I switched to Apache2+PHP and haven't looked back. I can't suggest the ISAPI plugin since it's listed as "buggy", but it makes me wonder if the plugin is really buggy, or if IIS has issues with external scripting engines...
I've got a VisionTek GeForce4 440 MX ($120, Insight) running two 19" Trinitron monitors at work. The newest drivers do support running a true dual-monitor mode (not stretched desktop) on Windows 2000. For any multi-monitor system worth its' salt, this is a must.
Now, about the 3 reboots it took to make it all work...

Yes, I could have recommended that my clients buy bigger hardware but when a summary table can be used instead of spending $X thousand dollars, what do you think you would do?
I would use an Oracle Materialized View and get the speed increase without the extra dollars and without needing the extra hardware. Work smarter, not harder.
I have an Oracle contract in front of me. Name one other vendor that has the following clause in their software agreement *by default*...
"If Oracle cannot substantially correct a breach of Oracle's warranties in a commercially reasonable manner, you may end your program license, technical support, or other services and recover the license fees, technical support fees or other services fees paid to Oracle under this agreement..."
This no-nonsense agreement was a selling point for my company. If Oracle can't fix the fuck-up, they'll give you your money back. Period. In the contract. No verbal agreements. It's in writing.
I have never lost data using Oracle. Not once. I've had bad sectors on different hard drives crop up and Oracle has ALWAYS been recoverable. Yes, it's more expensive than a solid-gold custom-molded toilet seat with a free midget butt-wiper, but for data integrity you just can't beat it.

This isn't an excuse, just an explanation:

If you train well (i.e. can read a manual and learn, not go DUH), then estimate what it will take to build it then double that number.
Database - About 2 weeks with populated test data.
GUI - About 6 weeks.
Interface to other system - About 6 weeks.
That's 14 weeks, so double it to 28 weeks. Your project will take about 7 months to complete with one developer.
