Re: Network interference Brad Fackrell21-Mar-07 8:22 Brad Fackrell 21-Mar-07 8:22  Here is one camera that I was looking at: http://www.dlink.com/products/?sec=1&pid=459[^] This one doen't say that it will send an email when motion is detected but it does detect motion. Re: Network interference Brad Fackrell22-Mar-07 5:31 Brad Fackrell 22-Mar-07 5:31  I found a better one here: http://www.gadspot.com/product_info.php?&products_id=57[^] ...it has sound and IR. I would like to ativate the app with sound or motion if possible. Re: Network interference code-frog11-Apr-07 15:34 code-frog 11-Apr-07 15:34  Okay, I ordered one of these they were back ordered and it just got here today. Stay tuned. Re: Network interference code-frog11-Apr-07 15:34 code-frog 11-Apr-07 15:34  It looks pretty nifty. Re: Network interference code-frog12-Apr-07 5:18 code-frog 12-Apr-07 5:18  In the web interface you can configure an "Intrusion" sensitivity that will react to "Motion" and send an email. Seems pretty cool! Opteron 22xx and the dotnet platform Genbox13-Mar-07 9:00 Genbox 13-Mar-07 9:00  Hi. i'm about to buy a new computer for programming as my old one is nearly dead when it comes to compiling. The new computer contains 2xOpteron 2214 2Ghz processors, is that a bad choice when it comes to C# development? Does the opteron run with a diffrent platform? or are they still x86-64 compatible? Re: Opteron 22xx and the dotnet platform Dan Neely13-Mar-07 10:11 Dan Neely 13-Mar-07 10:11  For most projects that's overkill, but if you're compiling a big project or hosting a large local DB you can never have too much hardware. Opterons are the high end server/workstation version of the Athlon64, they're x86-64 chips. -- Rules of thumb should not be taken for the whole hand. Dell Optiplex disk size limit Steve S13-Mar-07 1:28 Steve S 13-Mar-07 1:28  According to the Dell Optiplex 745 technical specification, SATA-II drives of up to 250GB are supported. I have a couple of these systems with one such drive in, and now want to put in a second drive. Is the size limit a BIOS limitation, or just marketing fluff? Has anyone successfully added a larger disk to one of these? (And I'm still smarting from the 'feature' of Symantec AV Corp Edition which stopped these puppies from booting, even in safe mode, until I applied a registry patch. Talk about 'fitness for purpose', although I suppose Symantec's legal weasels would argue that you cannot become infected by a computer virus if the computer won't boot, so it provides the protection they're claiming...) Steve S Developer for hire Re: Dell Optiplex disk size limit code-frog13-Mar-07 2:54 code-frog 13-Mar-07 2:54  I think that's a per physical disk limit but you can have as many at/under that size as you want (at least that's what I thought). But it's Dell. Have you asked on the Dell Community site? I ask that not meaning to push you off or be a smart @$$ I'm really just wondering if you have and what kind of response you got. http://www.dellcommunity.com/supportforums[^] My name is Maximus Decimus Meridius, Commander of the Armies of the North, General of the Felix Legions, loyal servant to the true emperor, Marcus Aurelius.

Re: Dell Optiplex disk size limit Steve S13-Mar-07 5:00 Steve S 13-Mar-07 5:00  I have two free SATA connectors internally, (since there are four, one in use for HDD and another for DVD), and I am assured by Dell that I can connect in another hard drive. I looked on the community site first (of course!), and it kind of implied that there used to be a BIOS cap, but that this doesn't apply to SATA drives, so it doesn't really answer the question. Dell have a vested interest in this, since they want to sell me their drives, and point me at the literature which says up to 250GB per drive, so I don't expect a thorough answer. Empirically, I could determine it, but I'm not buying a bigger drive just so I can try it, since I'd then lose on reselling the drive if it didn't work. I wondered, therefore, whether anyone frequenting these forums had done this already. Steve S Developer for hire Re: Dell Optiplex disk size limit code-frog13-Mar-07 5:09 code-frog 13-Mar-07 5:09  Well the short answer is no. I have not done this. I've stacked in two SATA drives at 320 gigs and 160 gigs and not had any trouble. That put me at 480 gigs total but I'm not even sure if there was a cap on that particular system. You are right to not trust Dell in that regard. I just recently learned (and almost regretted) that if you buy one of their servers don't plan on much freedom for IRQ's and adding devices you just won't have the option. All I wanted was dual video cards and getting them to work proved to be an exercise in patience and practice. I think I shot 40 hours right out my behind getting them to work (and I did get them to work, even though Dell said it wouldn't). So I at least cannot give you a definite answer but hopefully others can. I'd be willing to bet a silver dollar you should be able to drop one in and not have any trouble. But certainly don't try that because my remarks inspired you to do so. You'd have take that decision under your own advice... if you do go that route keep a bottle of Advil close by and you should be okay. "Numb the pain and the brain will follow."

Re: Dell Optiplex disk size limit Steve S19-Mar-07 8:18 Steve S 19-Mar-07 8:18  The Optiplex GX620 isn't "protected" against adding a larger drive, as I've seen a 750GB drive and a second 160GB added into one, although of course, there were additional cables required, since the chassis only has power cables supplied to the first and second drives, so an extra power cable and 2 data cables were needed. Now if only they'd let me borrow the 750GB drive ... Steve S Developer for hire Limited or no connectivity!!

(\ /) (O.o) (><) RAM Performance t-mhill12-Mar-07 2:04 t-mhill 12-Mar-07 2:04  I am in the middle of writing a program that calculates the performance of different algorithsm. Im trying to implement a class that can estimate the peformance before any calculations have taken place. Obviously RAM/CPU speed will have a very big influence, so i have taken numerous calculations using machines of different specifications, however i need to fit a Trend Line to it. Does anyone know an 'estimate' to RAM/CPU Performance i.e Log, Exponential, linear? Thanks MH Re: RAM Performance Alexander M.,14-Mar-07 2:31 Alexander M., 14-Mar-07 2:31  Measuring CPU is easier than measuring ram. You create an algorithm without heavy memory access and a loop calling it. now you can either set a constant loop count and measure the time to execute, or you create a multithreaded application and interrupt the loop after a fixed timeout. RAM is more difficult, as you need to access it using CPU instructions... That means, that the score will strongly depend on the kind of algorithm you use to measure the performance! I'd suggest using SSE instructions, since you can bypass the CPU cache that way. MOVNTQ for example. Most benchmarks I've seen use a linear scale to measure both CPU and RAM. But that also depends on how to evaluate the score with you application. Don't try it, just do it! How to get infomation of Filesystem on USB drive? nguyenvodich12-Mar-07 1:22 nguyenvodich 12-Mar-07 1:22  I am writing a program that can recognize which file system is being used on an USB drive when USB is plugged in.(FAT 16, FAT 32 or NTFS) How can I do it?

Steve S Developer for hire usb drive prathuraj11-Mar-07 23:05 prathuraj 11-Mar-07 23:05  what is file system for usb drive. Re: usb drive Sebastian Schneider12-Mar-07 0:56 Sebastian Schneider 12-Mar-07 0:56  You will usually find that USB pen drives are preformatted with FAT or FAT32 by the manufacturer. You can, however, format them with other filesystems. The FS of choice is FAT32, though: MacOS, *nix and Windows can all handle it. With USB hard drives, it depends on your mode of purchase: If you purchase the IDE2USB interface seperate from the drive (or if you are upgrading an older HDD), you might not have any partitioning or formatting on your disk at all. If you buy an off-the-shelf solution, you might end up with an HDD preformatted with NTFS or HFS+, depending on the sticker on the box ("Mac-Ready"/"Vista-Ready"/etc).

Right-click it and pick Format. You have your choice of NTFS and FAT32 on an XP box. Dave Kreskowiak Microsoft MVP - Visual Basic
