    Small A/C unit compressor type

    I'm curious as to what kind of compressor is generally used in small window-mounted air conditioning units. Because of size it would likely be a positive displacement compressor, but what type? My guess is reciprocating, just based off of how much my air conditioner vibrates when the...

    Launchd broken

    Recently I've been having a problem on my Mac where I can't connect to it with ssh or Windows file sharing. We've traced it down to launchd, an OSX daemon that starts services when needed. It should start up sshd or whatever process is needed for Windows file sharing when a connection is made...

    Is my CPU dead? PC wont boot ** CPU is good** now what

    It does sound like the CPU might be a goner. If I was you, though, I'd try my CPU in someone else's board before you go and get a new one. I'd be pissed if I spent a couple hundred $$ on a new CPU only to find that that wasn't the problem.

    If you install a new CPU and the mobo doesn't even post, is it a sign of a bad cpu?

    You'll have to try the new CPU in a known working motherboard, or try a known working CPU in your motherboard. That's the only way to figure it out for sure.

    Why do capacitors and transformers make audible noise?

    I need advise, which system to keep...the 3800X2 at 2.65, or the 2xXeon system with HT, at 2.5 each

    Without a doubt, the X2. It's got a faster clock speed, and it's faster clock-for-clock to begin with. Hyperthreading really only helps when you're multitasking and you've only got 1 CPU. It can make things smoother. But if you've got dual cores already, Hyperthreading won't do a lot for you in...

    Coaxial vs. HDMI

    Yeah, the only real reason that HDMI cables are so expensive is because they're new. That, and a lot of places overcharge for cables no matter what type.

    what makes flatus smell more in the shower?

    I always assumed it was because you don't have any clothes on, so there's no hindrance to the escape of the flatus, so it's more concentrated.

    Is it a bad thing that Windows, OSX and *nix all use the x86 architecture?

    Bad why? There is still competition between x86 CPU makers, so there's no serious worry about monopoly-related problems. As far as competition driving development of better ISAs, that may or may not be important. I personally am not a huge fan of x86 (have you ever seen x86 assembly code? it's...

    Power PC

    First, the PS2 doesn't have a PPC processor, it's MIPS. PowerPC has a history of being customized for specialized applications, whereas x86 has only been used as a general purpose PC architecture. None of the chips used in consoles are the same as have been used in Apple computers, just as...

    Which is worse for your car?

    Rotary engines are a lot more resistant to that kind of thing than a standard piston engine. In a normal engine, the pistons are going up and down, always changing direction, whereas in a rotary engine, it's just going around in a circle. A piston engine would seize a lot earlier than that...

    MAKE - possible to access the dependency list of another target?

    Yeah, I could, that is better than nothing... But the way it's set up, there's one "platform makefile" that has all the rules for all the targets. Then there are individual makefiles in different directories, depending on what you're building. The individual makefiles have the dependency...

    MAKE - possible to access the dependency list of another target?

    I've got two targets in a makefile that should always have the same dependency list, but since I may want to build them separately, they do need to be separate targets. Is there a way to have one access the dependency list of the other, so that I don't have to manually keep the two in sync?

    Altec Lansing XA3021

    Have you tried a new cable? Have you opened the thing up to see if anything's loose? I can't really tell you anything without looking at it, but it sounds like either the cable's bad, or there's a loose connection near the jack on the woofer. This is also probably not HT.

    Is there ever a reason for a large kernel?

    The kernel is the very core of an OS. It handles things like IO, the filesystem, process/thread scheduling and interprocess communication. For more information, wikipedia: http://en.wikipedia.org/wiki/Kernel_%28computer_science%29

    Intel P4 2.0GHz = AMD 64 3200

    Way to many question marks! (haha, just kidding) I think a lot of the people who make up the system requirements for games have no idea what they're doing. Obviously an Athlon 64 3200 is much much faster than a P4 2.0GHz or an Athlon XP 2200.

    Digital camera buffs...can a memory card have any effect on picture quality?

    Small bit-errors probably do happen in flash memory. Unless there's something wrong with the card, they'd be extremely uncommon, and even if one or two bits is flipped, it won't have an impact on the picture. And if there is a problem with the card, it won't work period. Short answer: same as...

    OP, I think the reason you're not getting any constructive replies is that everyone here's just waiting for the mods to lock this thread. This thread isn't highly technical! You'd have better luck getting constructive responses in a different forum.

    OS X: Possible to start .app from command line?

    Thanks for the replies, and sorry I've taken so long to reply. School is pretty hectic around now. Anyway, open does work, and it's a very handy utility. Unfortunately, it looks like when you run the program as an "app," it's unaware of any kind of X11 forwarding. For that, you have to dig...

    OS X: Possible to start .app from command line?

    Most Mac OS X programs are distributed as ".app" packages, which are basically directories with the required binaries and resources for the program. You run them by simply clicking on the ".app" directory (which doesn't look like a directory unless you're at a terminal). At any rate, I'm...

    Dual head, two keyboards, two mice?

    You'd need some kind of 3rd-party software (or write some yourself) for Windows. Unless you're running Windows inside a virtual machine on Windows, that doesn't make any sense. If you're running the OS natively, you can't run 2 at the same time.

    Using flash dive (thumb drive) as Ram

    Each cell in the flash memory has a limited number of read/write cycles. I think it's something in the range of 10,000 or 100,000. So if you re-wrote to one cell 100k times in a row, it would probably die. However, flash controllers mitigate this by writing to many different cells, not the same...

    Project with FPGA?

    I think what you're talking about would be doable. I'm not sure how much you know about the math required, but it sounds like the labs you're doing should prepare you pretty well. I do think that doing it from a file is a good idea. At first I assumed that you'd be trying to stick it in a...

    Weird squeeky sound?

    I've heard it too. It puzzled me, because it sounded like it was coming from the CPU, but I couldn't think of why the CPU would be making a noise. I read an article about Apple PowerMac power supplies making a "chirping" noise when the CPU changed power states, and I believe it's the same thing...

    ssh into OS X with X tunneling

    I have a Mac at home that already has sshd enabled, so that I can connect to it remotely with SSH. I also have X11 installed on it.

    What is the difference between dual-CPU dual-core?

    In the Athlon 64 X2 and Core Duo / Core 2 Duo, the two cores communicate basically through the L2 cache interface, which is very fast. Older Intel dual-core processors (Pentium D and it's derivatives) and 2 separate physical processors communicate over the FSB, which is slower. So as a rule, a...

    If your power goes out, can you power your Vonage equipment through existing phone lines?

    No. Not at all. First, the cable modem needs power to run, so you won't have any Internet connection. Second, the amount of power a phone carries is pretty small. I've seen varying numbers, but howstuffworks.com says that the phone line provides 6-12VDC and about 30mA of current. Another place I...
