There is a reason why the shuttles have launch windows - to get into certain orbit. If the interval between those windows is too long, then the rocket solution is kind of useless
You can get into any orbit you like, as long as you have the fuel. Also, the interval between the correct low orbit launch window isn't long. According to this page, there is a window each day. Thats not too long to wait.
plus they'd need an arm or something to catch the payload.
A docking collar would be sufficent, the shuttle can manouver precicely enough to dock with the supply capsule. A while ago I read that the MMU (manned manouvering units) that were worn by astronauts to free-fly out to sattelites were mothballed because they were not needed, as it was possible to manouver the shuttle with sufficient accuracy to fly the satellite into the cargo bay, rather than sending guys out to the satellite.
Why not stick a couple of Soyuz escape pods into that payload for the shuttle crew to bail out and abandon the orbiter?
I don't know what Soyuz capsules weigh, but I bet its not light. Plus, you'd lose one of the primary resons for the shuttles existence - its much vaunted but hardly used ability to capture sattelites and bring them back to earth (unless you ditched the Soyuz each time they weren't needed...)
Also, launching the shuttle into orbit w/ ISS creates a possibility of an accidental collision between the two, if one becomes incapacitated.
No. Space is a big place. There is lots of room in LEO. Anyway, things in orbit follow easily predictable paths. If the shuttle, or ISS becomes incapacitated, it will continue to drift along in its current trajectory (for the short-medium term anyway). Their positions are easily predicted months in advance, and can be tracked by ground radar anyway.
Find me another manned spacecraft that has an aircraft shape. Buran's only flights were unmanned.
Find me another spaceship that can brink sattellites back down to earth from orbit.
Buran wasn't the same shape as the shuttle because the russians stole the plans, its because they looked at the problem (reusable spaceplane) and realised the shuttle's shape is the most practical design.
I heard a very sensible sounding option just after the Columbia accident which has since faded away, which would seem to give the best of both worlds: it leaves the door open for an orbital rescue, without the expense & bother of having a 2nd shuttle prepped to go.
Instead of either having a shuttle on "warm standby" (which must cost millions per day) or skimping on the normal procedures to get rescue mission up there before food, air & power run out (playing double or nothing really), isn't it more practical to have an unmanned rocket stocked with supplies standing by that can be lifed off with just a few days preparation.
This rocket could be fueled and match orbits with the damaged shuttle, and the shuttle could dock and take the supplies onboard, and then the astronauts major problem before a properly propared rescue mission arrives would be boredom.
Maybe chuck a few gameboys onto the supply rocket;)
The last chip that worked without a fan was the 486DX33 and 486DX40
Not true... I just picked up an old p3-450 compaq deskpro that work was gonna chuck (for a home webserver) and its got a friggin HUGE aluminium heatsink, and no fan - just a medium sized fan on the back of the case to circulate air
I assume you're talking about windows XP - Ealier versions of windows will search inside files using a standard plain text search. XP tries to be smarter by using the file extension to work out how to open the file, but it ends up being a pain because it does nothing with files it doesn't have a registered handler for.
Map any file extension to plain text search with the.vbs script you can download from here
I know! A use for.vbs scripts that isn't a virus! I was just as surprised as you:-)
I think Opera will survive, they will keep following some niche market. I just gave them US$40 the other day, for Opera S60 - a brilliant piece of software. Full-blown webbrowser for my nokia 7610, which renders pages extremely well on the small screen and even does Javascript!
Yeah, just last night I was playing one of the arbitier levels, and I was pinned down by a bunch of brutes with grenade launchers and jackals with sniper weapons. There was another elite with me, and a grunt.
The grunt was pretty much hiding behind a box and doing nothing (as usual)... The other elite turned around to the grunt and said "Get out there and fight or I'll shoot you myself"
And he did!
Its the little touches like this that make Halo 2 the best FPS I've ever played.
I used to play a lot of FPS on the pc, and using mouse and kb definitely allows for more pinpoint accuracy, no doubt.
But once you get used to the controller, I think it makes for a much more immersive experience. When you're using a mouse/kb, you still have to think about what you're doing, but using the controller becomse completely automatic after a while.
And I've never had any complaints about the xbox controller, yes the first version was a little large but I've got two of the smaller ones and I find them far more comfortable than the pc2 controller.
Yeah, I know... I think one of the reasons for this, is most screensavers are either totally lame, or they max out your cpu/vid card. These days, the difference between your cpu running at 1% and 100% is several 10s of degrees, and a measurable difference in your power bill.
Give me a nice tasteful screensaver that doesn't tax my system, and I'll use it. I used the matrix screensaver for ages!
If you use the "find handle" function, and enter the filename, or partial filename, it will list the processes that have this file opened. The find dll function is similar, but finds all processes that have loaded the specified DLL. Very handy for spyware that lives in a dll and has loaded itself with rundll.exe...
Its an incredibly useful tool. Its one of the first apps I install after a rebuild.
This is the technique that is used to colourise old B&W movies, but the choice of colours is quite arbritary. The operator decides to make the shirt blue, and the computer uses the brigntness information to shade the shirt so it looks kinda like you'd expect. The process is far from perfect tho, a colourised movie is easy to spot.
Think of finding a colour on a colour chart - you need three channels to specify the colour.
Take a pixel from your black and white image. You only have one channel of information, and you have no way of determining the other two channels....
No, its not possible. Monochrome has one channel of information (brightness), and colour has three (Hue, saturation and value, or red, blue and green.)
Where I once worked there was a guy, who was a software dev, and a smart guy, who was 100% in the creationism camp. One day me and another guy I worked with (Tom) were questioning him about his beliefs.
We said, "So, you beleive that earth was created 2000 years ago?" "Yes."
"And the fossils and things, were they just put there by god to test our faith?" "Yes, of course."
So Tom said to him: "So... how do you know the earth is really 2000 years old and the older stuff was created by god then? Maybe the earth is only 500 years old, and everything before that was placed there by god... Maybe the earth was created when you were born, and everything before you was put there by god."
"Infact, maybe the earth is only 5 minuites old, and everthing older, including all your memories was just placed there by god?"
We left him at his desk thinking about it. He looked troubled.
Don't panic too much about the "mem usage" column in task manager, as that figure includes things like shared libraries, so lots of things are counted twice, or more.
Download process explorer from www.sysinternals.com, which can give you much more interesting information, like private bytes (total non-shared memory) or VM size (total memory)
The mem usage column in task manager is actually the processes working set, which is (I think) the total memory used minus the memory that is paged out to disk. Minimize a window, and notice how the mem usage for that process drops waay down, as minimizing the window makes windows page all of the process's memory that hasn't been used recently out to disk. Then resotore the window, and as you start doing things with the app, the mem usage goes up as the app requests memory that was paged out to disk.
Ahh, good thinking, IISLockdown probably would block this - the URLScan component probably translates the \ in the url back to a / before.Net sees it.
I couldn't replicate this problem on my local machine here tho, which doesn't have IISLockdown or URLscan installed. I created a basic website with a couple of pages + a login page, using forms auth, with the login redirect in web config pointing at the login page. Goint directly to http://server/vdir\samplepage.aspx (in moz) or http://server/vdir%5Csamplepage.aspx still redirects me to the login page. How did you replicate this? Cheers
Also, its now obvious to any would-be hijackers that the passengers will not let them accomplish their objective, so its unlikely they would be stupid enough to try.

I'm not a fan of MySQL tho. Yes, it is fast... As long as you are only querying data.
If you have multiple users updating data, MySQL isn't such a good option.

Its probably a flash advert on that site with a script that is continuously running. I've noticed it on a few sites.
Download the flashblock extension - until you slick on the flash items you'll only see an icon.
No, its not possible. Monochrome has one channel of information (brightness), and colour has three (Hue, saturation and value, or red, blue and green.)

> I'm not familiar with what "VRLA" means
and you call yourself a nerd??
A quick google for "VRLA battry" found this page.
Apparently VRLA means Valve Regulated Lead Acid, and they are a type of sealed lead/acid, you the parent poster should be alright.

No, DON'T do that automatically.
Many people, like me, are reading slashdot at work (shhh) where their firewall won't let you get to port 8090.
Yeah, I'd say you were too.
You're completely correct... which is why MS provides SQL server session state.
I've read that using the SQL server state service is 80% as fast as in-process state.
Thats not a lot of overhead...
This entire case was setup by ms
Eh? do you know something I don't?
I know we all hate Microsoft, but blaming them for this is just hurting your credibility.
Or do you blame Microsoft when it rains in the weekend too?
