I did try to run "Atomic Clock free" application and it just did not do anything - no synch at all.
I just "finshed" running backup (MS) and I eneded up with "days to finish"
after it run for about ten minutes. Obviously it is no good.
I think I have a hardware problem saving the current time.

The only thing I can suggest then is make sure there isn't some BIOS setting that went haywire, maybe there is a way to disable the real-time clock (RTC) and it got checked during the troubles.

The RTC chip is probably a goner.
Does your PC start very slowly through the BIOS sequence, and then speeds up when some the NT Kernel is loaded? Then it's your RTC chip. (NT does not care about the RTC chip to do it's clocking, but most BIOS-es do, to time the stuff they display)
You should be able to replace it cheap. The only problem is that nowadays, these things are surface-mounted, so it's a bit tricky to replace them.

Old Dell Poweredge server hangs about once a month for the past six months. This has one SATA hard drive and a RAID 5 array of SAS hard drives.
The last time Dell Poweredge had the following error
"Backplane unknown sensor type sensor #29, drive slot sensor drive fault detected"
Every two to four weeks, the hardware logs issues with the power cords such as
AC Source B Power Cord Inserted
AC Source A Power Cord Removed
Ocassionally the server reboots or hangs with a message about the PERC 3/i RAID controller
All changed files are backed hourly on another machine on-site and out of state overnight
The server is no longer under warranty
What is a good interim solution short of buying and setting a new server? This no longer hosted a database, so it's strictly manages our network, policies, and security permissions. Is it possible and should I consider disabling the RAID controller? Should we clone the SATA hard drive and replacing that?

You probably have a hardware failure that's going to get worse and worse. From the description you gave, I be worried about an actual drive failure, RAID controller failure, and a power supply failure. So, take appropriate steps to protect your data and consider your options for continuing functionality.

What is "USB bandwidth"? I run into this somewhere, I think it is in Properties of some USB ports..
What about "the USB on front are different than in back"? Not too technical description, referring to desktop box.
I got USB to IDE "converter" to run CD drive and it is noticeably slower that IDE. Is that “bandwidth” limitation?
NT “Device Manager “ identifies tons of USB controllers, how do identify them physically?
I mean where are they - on the motherboard or on PCI adapter ( BTW I took it off – got too many internal USB ports) or external D-link USB adapter?
If I can change this “bandwidth” I need to know this.
Thanks for reading.

that's how fast a usb port can send data. For a USB2 port it's theoretically 480Mbit/sec. In practice with overhead factored in it's only about 40 MByte/sec.
Vaclav_Sal wrote: What about "the USB on front are different than in back"? Not too technical description, referring to desktop box.
Depends on the manufacturer, but in general they're the same. The most common exception would be a system old enough it only had USB1 ports and had USB2 devices added by an expansion card.
Vaclav_Sal wrote: I got USB to IDE "converter" to run CD drive and it is noticeably slower that IDE. Is that “bandwidth” limitation?
Maybe. PATA is capable of 133MByte/sec a bit over 3x as fast as USB2. however a 48x CD drive is only capable of sending up to 9MByte/sec which shouldn't be enough to cause any problems. If your computer is so old it only has USB1 ports the drive would be limited to 1.5MByte/sec which is about equal to an 8x cd drive. This would be enough to cause noticeable slowdowns. XP would warn you that you're putting a 2.0 device in a 1.0 port and that it will be running slower. I don't recall if win2k did this or not.

If you look at your mobo/its manual will probably have the ports numbered. I'm not sure if you can get matching IDs in device manager or not. If you pulled the expansion card though all the ports should be on your mobo. AFAIK Using an external hub shouldn't change anything in device manager because everything on it will be connected through a single port on your mobo.
Vaclav_Sal wrote: If I can change this “bandwidth” I need to know this.
You can't. It's a hardware limitation. The only thing you can do is if your mobo only has 1.0/1.1 ports is to add a 2.0 expansion card to have some faster ports for external drives.

I was happily developing on my Windows 2000 1.6 GHz Pentium PC when my geeky son-in-law railroaded me into "new computer is the answer".
Now I got dual processor 3.0 GHz piece of flaky, undependable....
I did not expect much improvement in compiling time ( For what else would developer want faster machine?). I have read here, somewhere, that VC++ was not designed for dual processor.
What is frustrating that I for example cannot start several directories copies with single click as I used to do on the old single processor. I understand that actual copying speed cannot be improved since I still copy from one slow device to another (disks).
But the windows management seems to be sluggish.
Does that mean that Windows 2000 was not designed for dual processors also?
Just curious.
Please – any commentary on obsolesce of my OS and or VC++ are not necessary nor welcome.
Thanks for reading.

Win2k pro does support dual-processor (and you dual core should like identical to two single socket CPUs windows). The biggest limitation is it doesn't understand hyper-threading; but that's only an issue in scheduling when you have 2 more more HT capable cores. However I know XP had separate HALs (low level components) for single and multi-processor systems and didn't have a supported method to switch between them without doing an OS reinstall. (Starting with vista, the performance hit on the small fraction of uni-processor systems was considered to be less of a concern than the dev effort of maintaining two code bases.)
XP allowed swapping the HAL via tools intended for driver devs. I've no idea if it would work in wink2 as well or not. I'd strongly recommend making a backup before trying because if it goes wrong your windows install will be fubar.

Thanks for reply.
I was actually hoping to see some impovements in regenerating RAID 5.
Every time OS ( actully the dynamic disk service to be technical) runs regeneration it just takes over the processing. Other than that I am content. Sort of!
Vaclav
PS I run Advanced server - just for the RAID 5!

If that's your only problem I'm 95% sure switching to a multi-processor HAL will serve as a fix since your second core will still be free while the raid is rebuilding.

I'll try it as soon as it is back to normal! My VC++ was doing goofy things so I am rebulding it right now. Of coure RAID 5 is aslo regenerating for other reason.

Hi,
I have a video camera connected to a PC based video recorder and I need to trigger a reading on an A/D card in the PC for each frame from the video camera (possibly synchronized to the frame sync of the video signal).
Is there perhaps something in the video capture driver that would allow me to do this? We haven't selected the capture card yet so if anyone has had some experience with a particular one I would be very interested.
Any suggestions would be welcome.
Thanks
Tony

What sort of level are you considering working at? It's been 10 years since I did a similar thing at an SDK level but from the manual of the (that version now obsolete Bandit) frame grabber card I still have, I see it has programatic option to synchronize frame grab with an external trigger such as, perhaps, some signal associated with your A/D:
External Trigger Detection Methods
Description: Detection method values used by BD_GetExtrigDetection and
BD_SetExtrigDetection.
Values:
BD_EXTRIG_DETECT_NEGATIVE_EDGE: External trigger detected on falling
edge of trigger input.
Again at a programaming level I recently used a Firewire bus to connect to a camera and was able to program what to do when a frame was grabbed:
LRESULT CMainFrame::OnVideoGrabbed(UINT , WPARAM wParam, LPARAM lParam, BOOL& )
{
LPTSTR lpFileName = (TCHAR*)wParam;
BOOL bGrabbed = (BOOL)lParam;
if(!bGrabbed)
{
So the type if interation you want is possible by various mechanisms.

Thanks,
Thats the sort of information I was looking for. Both solutions appear quite workable but I guess that it all depends on what the frame grabbing board/software supports.
I have found it difficult to get this level of information before you spend your money (and these things aren't cheap). For example I have tried without success to get this type of information for an Advantech board.
Still, it's useful to know that I am not asking for the impossible. All I have to do is check the various web sites for SDK documentation.
Thanks again

I have a wireless camera with RGB exit cable (PAL) and I was planning to control the video via C++ code
The idea was to use something like EasyCap adapter (RCA to USB with a driver CD) to let the camera play video in my notebook but the question is: how to control the video stream via C++? I don't think the included drivers could be controlled by code
Any idea on how to solve the problem?

I need a laptop with 12GB or more of ram anybody know of one...
I cannot afford the dell m6500.
I need that much ram but I do not need any frills just horsepower any suggestions?

Don't know how much dell m6500 costs. This one comes with 6GB RAM and is upgradeable / customizable to 16 GB, which is the most recognizeable on windows 7 home premium OS.

Here's a cheaper laptop where you can spend around $1,600+ for 8GB of RAM with LED screen.
http://www.avadirect.com/product_details_configurator.asp?PRID=16495
I personally would prefer a dual core cpu (core i7-620M) if I was only using the machine for non-database software development and web browsing.

I am probably going to get a new machine because my boss is wanting to do our develop in VMWare. I am wanting to get the most bang for my buck. Does anyone have experience using dual core vs quad core processors for this type of dev. We are writing VB.NET apps and are fixing to move to Windows 7 64bit and Visual Studio 2010 64bit. I know I need a ton of memory, not sure how much I am thinking at least 8GB. I am also wondering about solid state drives I have read these actually decrease VS performance.
In summary which is better
2.0ghz quad OR 2.6ghz dual
Solid state OR 7200rpm sata... It has to be a laptop I have not seen any faster drives.
Windows7 will have nothing installed except essentials and VMWare withing VMWare we will run Windows7 with dev tools.
Any opinions thank you
BTW I have googled this to death and most info I find is dated and with the improvements to solid state etc that is why I was wanting to ask someone that might have actually used it.Humble Programmer

I'd rather pay for more RAM (16GB, if doable) than for solid-state disk (RAM is cheaper than EEPROM).
And IIRC people are not overwhelmed by Visual Studio using multi-threading, so maybe the faster dual-core is the better choice.

Are you referring to 2010 or 2008 VS?
Do you know if I will see a big difference in 64bit vs 32?Humble Programmer
|

mostly VS2008 (the real VS2010 isn't available yet).
you can't use more than 4GB of RAM without Win64, and RAM is your biggest friend.
by itself, some people have claimed Win64 is faster than Win32 on the same amount of RAM, however I am not convinced I understand how that would be.
FWIW: I would be looking for an Intel Mobile i5 (latest chip technology = most activity for given dissipation budget; and hyperthreading, i.e. each core has two sets of registers, hence can run two threads intertwined).

Any opinion on the SSD vs regular hard disk...
The things I have read have said there is no real improvement but most of that info is dated at least a year.
I also wonder when they are comparing these hard disk are they comparing a mid range SSD to a velociraptor ?
I cannot get a 15000rpm drive for my laptop as far as I know so would the SSD be better maybe.Humble Programmer

DRAM memory is faster than most other types of solid-state memory; it sure outpaces EEPROM. The one faster RAM technology is SRAM, but they are "small" (CPU caches are made of them).
On a Win64 system I would never buy and install SSD for speed reasons (maybe for fast boot, reliability, power considerations, ...); I would always opt for lots of DRAM and rely on Windows file caching, and if and when not satisfied by that, install a RAM disk (haven't seen many of those lately).
