At Tech-Ed last year I went to a security session by Jesper Johansson - He's Microrosoft's senior security strategy guy. He's very smart and an excellent presenter. Anyway, he called HTTP "UFTP". After everyone wondered what he was talking about, he explained - Universal Firewall Transversal Protocol
Amen to that. I had back surgery for a bone tumor 12 years ago when I was 20, and my back has been kinda fragile ever since (due to me missing part of one vertebra in my lumbar spine...)
I got a neeler like the submitter linked to immediately, and it was very good - I just couldn't sit in a normal chair for several years. You have to be dilligent sitting in a neeler, sometimes I catch myself slouching and leaning on my desk.
Also they tend to make your shins/knees sore after sitting in them for a long period. I couldn't sit in one for extended periods, and I tended to alternate with a normal chair throughout the day.
I had issues with back pain at work, right up until I started at a place with aeron chairs - then suddenly I had no back problems, and my back was as strong and pain-free as it had ever been, and I never used my kneeler
After a couple of years I left that job (around xmas last year) and within a few weeks I was getting really bad back pain. I had a crappy chair so I complained and I got a better one, but still nothing flash. It helped, but it still wasn't good. I was using my kneeler most of the time, spent half the day spaced out on painkillers and had to see the osteopath a couple of times a week. I was doing numerous exercises too, which helped, but couldn't take the problem away.
I scrounged through second hand office furnature stores and I found an old german-made chair (can't remember the brand) that felt good, so I got it and I've had no back problems.
So moral of the story - get a good chair, doesn't matter if its an office chair or an ergonomic chair. And exercise.
The very cool thing about CTEs in SQL 2005 is you CAN reference the query name inside the query that defines the subquery. It references itself; it automatically recurses when it is executed.
WITH CTE_Example (EmployeeID, FullName, BossID, Depth) AS (
SELECT EmployeeID, FullName, BossID, 0 AS Depth
FROM Employees WHERE EmployeeID = @boss_id
UNION ALL
SELECT Employees.EmployeeID, Employees.FullName, Employees.BossID, CTE_Example.Depth + 1 AS Depth FROM Employees
JOIN CTE_Example ON Employees.BossID = CTE_Example.EmployeeID )
Have you got a reference for that "10 times faster than a p4" quote? I saw that and was impressed, but I looked colossus up on wikipedia and apparently colossus used 1500 valves. A valve does the same thing as a transistor, and I find it extremely hard to believe that 1500 transistors, no matter how cunninly arranged to execute a single algorithm, could outperform 55 million transistors.
And I also doubt if they were switching several thousand million times a second. Yes, I know, many of those transistors are cache memory, but still...
And it wouldn't surprise me if this guy who has a matress cover thing to sleep on with those little magnets because of the "health benefits" of magnetic fields.
V (aka vitalize) originally came from New Zealand, but I know you can get it in the UK and Australia now too. It has caffine and gurana, and it gives you a really nice kick. I don't know any sales figures, but walking down the street you see more people with V than with coke, or anything else.
You can get V Black now, which has a yummy cola taste, and double the taurine. Gives you a real kick.
One suggestion I've heard which never seemed to get debunked is send an unmanned capsule of some sort up to intercept loaded with food, water, oxygen etc so the crew had enough consumables to stay in orbit until atlantis could be prepped properly.
I've never heard this wasn't possible. It certainly sounds feasable.
Its the first piece of software that I install when I have to use a new PC. Its truely indispensible...
Another thing that is handy is how it shows % time servicing DPCs and interrupts. I was copying some video from my camcorder to my pc via firewire the other day, and I was having problems with dropped frames. The CPU was maxed out, but I noticed that about 40% of the time was spent servicing interrupts....
Bit more checking and it turned out my HD had fallen back to pio mode.
My day job is developing.Net software, and process explorer's.Net performance counters are very useful for that too. I used them to prove the memory leak in our software was our code's fault, not.Net itself. Architect:"Our code CAN'T have a memory leak -.Net has garbage collection." Me:"Well, how come the large object heap size reported by process explorer keeps going up, tracking the overall process memory useage?"
Turns out each object in a very large collection was reading a 200k file into a byte array, and never releasing it.... garbage collection can't save you there.
Written by Mark Russinovich, the guy who blew the lid on the sony rootkit debacle (and author of other indispensible free windows utils like process explorer, filemon, regmon and many, many others)
Autoruns shows EVERYTHING that is started on your pc at boot & logon etc, including device drivers, services... everything. It can even filter out binaries not signed by microsoft, to make third party stuff stand out like dogs balls.
Use process explorer to find and kill the spyware processes - you may have to google processes to identify them, but that function is built in. Here is a tip - look for anything that doesn't have a company name of "microsoft"
Some really stubborn spyware has more than one process running, watching each other and restarting each other if you kill them. Use PSKill (command-line process killer) to kill multiple processes at once, so they can't restart.
Once you have cleaned out the running junk, use autoruns to identify where it started from and kill it.
Its never failed for me, and you learn a whole lot about the internals of windows in the process.
Dude, ASP.Net is a massive leap foward from classic ASP. The difference is night and day. Benchmarks are pointless, but in my experience its 5-10x faster than ASP.
Its also much, much more productive to develop, and support. Its a nice stable, extendible extendible object-orientated framework that can give you most of a website with very little code (asp.net 2.0), or it stays out of your way if you'd rather do it yourself.
IIS has also moved on a LOT since NT4 as well. Its much, much more stable and secure. With ASP and NT4 remember you are talking about technologies that are about 10 years old now.
Make sure the "run in seperate process" setting is set on the account you are trying to use to run explorer. Makes sense really, the first thing explorer does when it starts is checks if it should shut down if it is already running, so when you use runas its using the setting in the profile of the admin user, not the normal logged in user.
See this blog post for more info: http://blogs.msdn.com/aaron_margosis/archive/2004/ 07/07/175488.aspx This is a very useful blog for running as non-admin. I no longer run as local admin, it really cuts down the risk of bad things happening if you pick up a virus or worm, or you insert a DRMed sony pseudo-cd into your drive...
If you enable the option on windows explorer "start each folder window in a new process" then you can then use the "runas" trick to start an explorer (NOT internet explorer) window that is running as admin.
Why not install SP2 and use a different firewall then? I hadn't heard about any SP2 firewall problems before, but I don't use it (MS's firewall) anyway - I use Kerio 2.1.4 (the last good ver before they became bloated)
My box has always been fairly stable, but even more so under SP2.

I have an ixus 750 (I beleive its known as an ixus 55 in north america) and there is none of the shutter lag you speak of...
This little camera is amazingly quick. It takes about 2-3 seconds to take the first photo, from SWITCHED OFF. about 2 secs to power on, waay less than a second to take the pic. If you prefocus by holding the button half-down, the photo is taken _instantly_
In continuous shooting mode it can take better than one photo/second, and thats at 3000x2500. Its even faster at a lower res (until the buffer fills up, if you have a slow card...)
Wrong, the win32 function TerminateProcess is the equivalent. Selecting end process in task manager does this, but task manager only lets you terminate processes you own. If you are an admin process explorer will let you terminate any process. The only reason this won't kill a process is if the process is waiting on a kernel call to return, I beleive linux does the same thing in these circumstances.
Wrong, "end process" on task manager calls the win32 function TerminateProcess. One limitation of task manager is you can only kill processes running as the logged on user - which excludes most services. As someone else said, if you use process explorer or similar you can kill services etc.
One thing you can't do is kill a process that has made a call to the kernel that hasn't returned yet. If you try and kill it it stays there (and unhelpfully there is no explanation) but if the system call ever returns the process will terminate - but usually this is caused by a buggy device driver, and it will never return.
I believe exactly the same ting happens in linux - its just not safe to kill a thread that is currently in the kernel.
If you select "end task" from the applications tab of task manager, that sends a wm_close message to the window you have selected, which asks the application to shut down gracefully.

On the plus side, when it goes boom, since its type 1a we wil know _exactly_ how far away it is, and whether we're or not we're screwed.

Ummm... Deuterium is common in sea water. Ever heard of heavy water? Thats H20, with deuterium instead of hydrogen.
Tritium IS fairly rare, but its easily manufactured in nuclear reactors. Check out wikipedia, I'm too lazy to search for you.
