Host ASP.Net WebSite - What would be an Ideal Hardware Configuration?

I am studying various ASP.Net deployment approaches. In there, I got a basic question. Is there any thumb rule about enviornment definition? What could be called a 'good' setup if I have to support 1000 concurrent users(requests). I understand that there are many factors like how application is designed etc. But assuming that everything...

How should I integrate a live video feed onto a website?

I have a client who wants to display live 24 hour footage on their website, to show off the progress of a number of big refurbishment jobs they are carrying out. I've looked at IP cameras and to be honest this looks like the most logical technology to use, but not sure if I'm missing something. Would it be possible to put the live feed ...

Developer oriented hardware benchmarks?

Perhaps I'm looking in the wrong places, but every hardware benchmark I've found, for nearly any component, is oriented towards gamers and/or workstations (video editing etc). Is there anyone doing benchmarks that are relevant to software developers? For example, take SSDs. I don't care how fast Crysis loads off an SSD -- that is comple...

Speed comparison between DRAM, HDD, and flash memory

The question: Assume that cache memory is ten times faster than DRAM memory, that DRAM is 100,000 times faster than magnetic disk, and that flash memory is 1,000 times faster than disk. If it takes 2 microseconds while reading from cache memory, how long does it take to read the same file from DRAM, disk, and flash memory? Does th...

Flush - Before the device read a portion of memory updated by CPU, CPU must flush(write back is also correct? ) the contents from cache to memory. ...

Is there a barcode scanner (hardware) with a .net api I can use to integrate into my app?

I understand the barcode scanner is like a keyboard and acts as such. What I need is a scanner that has some sort of api (.net/c# preferably) that i can plug into my app. Is there a particular scanner hardware vendor devs have used or are currently using, that has a .net api? or can I use any arbitrary scanner and build an api around it ...

Is hardware impossible to debug without software?

Disclaimer: I am (mostly) hardware ignorant. This is probably my problem. However I find it hard to accept that it is not possible to debug hardware so therefore I just wanted to get some second opinions. We have an issue. Where certain actions (swapping Usb devices in and out at run-time) can blow either the Usb hub or chip on our Usb ...

Is there a way to test a program's hardware requirements without just using it on a bunch of different computers?

Is there a program out there or some other thing that will run some kind of virtualization for me or something, to test the hardware minimums for a program I write? Something I can do locally without install testing on, say, a 33 mhz 64kb ram IBM or something ...
