    This has never been asked before. Regards gaming mostly..

    Basically, here are the steps from I/O poll to display output: 1) IO poll event 2) Game renders scene and sends to framebuffer. 3) If Vsync is disabled, framebuffer is immediately sent to display. If Vsync is enabled, the framebuffer cannot be sent to the display until the start of the next...

    This has never been asked before. Regards gaming mostly..

    I suppose what I said earlier was a little bit rash. (I'm not going to apologize for it too much, though.) That's just how double-buffering works. The videocard draws one frame ahead of time, but can't get started on the next frame until the previous one has been sent to the display...

    Radiation?

    I haven't worked with this stuff in years so I'll gladly defer to your expertise. I was just working off of memory. I tried googling for some figures first, but then I got lazy. My estimate for increased cancer risk is based on radon exposure (which I think has measurable health effects...

    Radiation?

    Nope, there's no ionization chamber. Instead, there's a Gallium-Arsenide diode.

    Radiation?

    Also, I apologize if my first reply was rude. Please consider how your OP looked from my perspective, though: *You mentioned buying a new Geiger counter. *You asked about the maximum radiation exposure limits for a human being. *It was immediately apparent that you didn't know how to use...

    Radiation?

    Natural uranium poses minimal health risks. For safety you should avoid handling it directly, but even then the risk is extremely small. That looks like a solid-state counter, and I don't have an experience with those so I can't give you any tips on using them beyond verifying its...

    Radiation?

    I have a little background in nuclear safety and physics, and it would be shockingly irresponsible of me to answer this question without knowing what the hell you think you're going to do. Geiger counters are very difficult to use and when you ask questions that conflate REMs with becquerels...

    How many Connections can server handle?

    Business-class cable Internet isn't going to cut it for this. Just run the numbers: 4000 simultaneous users all visiting within (say) ten minutes each trying to download at least 500KB of data off your server 4000 users * 500 KB/user / 10 minutes = ~30 megabits per second of upload...

    How many Connections can server handle?

    Is that 20 megabits down or up? You specificed Charter business cable so I assume that's the download speed, which means your upload speed is more like 2-5 megabits per second. You're expecting 1000-4000 people. I don't know anything about your website or how much content is on there, but if...

    Feedback on this SSD Pls?

    Also, performance on all current SSDs increases pretty dramatically when you go from 128GB to 256GB. It's a bit easier to find good deals on 256GB drives, too. If you're concerned with getting the best deal overall (rather than just a low price), it might be worth considering a 256GB drive.

    Feedback on this SSD Pls?

    Newegg had the 128GB Samsung 840 for $70 a little while back, and a refurbished 128GB Crucial M500 for $66 before that. Amazon had some great prices, too. I don't see any deals that good right now, though. If you're shopping on a budget, it might be worth waiting a couple weeks to see if any...

    How do I open a port?

    Use UPNP. There are some minor security issues with using UPNP, but UPNP with a firewall running on your computer is still probably more secure than port forwarding and no firewall. edit: MDNS-PMP does the same basic thing as UPNP, but doesn't have the security issues. I don't think your router...

    Wi-Fi being extremely slow. (Only sometimes!)

    I'm also voting for signal interference. Have you tried a different channel? Do you have multiple access points?

    What device am I looking for? (wired > wireless, 'reverse AP')

    I have a Linksys WET-610N (basically the same as the WES but with only one ethernet port instead of four). It's awful. The configuration interface is incredibly slow, which would only be a slight inconvenience except it also has the aforementioned glitch where connecting my laptop causes it to...

    Any consumer router than can handle 100mbps+ with QoS on?

    zero divided by zero - one, or undefined?

    |א^א| is something even a bit weirder than the power set of aleph. It's a shorthand for the Cartesian product of a countably infinite number of countably infinite sets - which is still countably infinite, surprisingly. Sometimes mathematical notation is weird.

    has anyone run an AM3+ socket CPU on an 870a-based motherboard?

    I do have dual BIOS. I might try that, unless someone knows where I can still get a good deal on a ~100w Phenom II.

    has anyone run an AM3+ socket CPU on an 870a-based motherboard?

    Gigabyte 870A-UD3 rev 2.1. Later revisions of that motherboard have BIOS updates that officially add CPU support for the FX series.

    has anyone run an AM3+ socket CPU on an 870a-based motherboard?

    I'm hoping to install an FX-series CPU in a socket AM3 motherboard. My current BIOS version is from November 2010 with support for AGESA 3.7.1.0, but there's a newer one from August 2011 that supports AGESA 3.7.1.2. Would I need the update?

    zero divided by zero - one, or undefined?

    No, it doesn't. All it implies is that any continuous infinite subset of R has the same cardinality as R itself. Notice that only continuous subsets have this property; that's why Cantor named it the continuum hypothesis. Cantor was fully aware of these issues, having been the one who discovered...

    Wireless file server accessible by iPad or Android tablets

    Kalemsoft Media Player (AKA Kalemsoft Remote Player) works on Android, and it can access media files stored on a UPNP/DLNA server if your router supports that.

    Internet Policy

    It turns out you can run an entire RADIUS server on any router that has DD-WRT, enough RAM and enough storage (or enough RAM and a USB stick). You can do this for $100 or so and the guys at the DD-WRT forum can help you set it up. I highly recommend this approach. Be warned, this will be...

    Are next-gen consoles gonna be gimped by their weak cpu's?

    You seem very technically informed which is why it surprises me so much that someone like you would say this. Pathfinding is an especially strange choice of an example, since most modern games are terrible at it. Fallout 3 used a very standard pathing system similar to what you describe; the AI...

    Wireless file transfer speed SO slow...

    I think you know your shit and I'm not arguing with you, but I have two wifi segments on channels 9 and 13 and there's no performance impact compared to using other channels.

    Wireless file transfer speed SO slow...

    1, 5 and 9 don't overlap. 11 overlaps with 9, but if someone is using channel 6 or 7, they'll overlap with 9 but not 11 (so he should still try 11 even if 1, 5 and 9 all don't work). A "single-wide" wifi transmission is 20MHz, and each channel is 5Mhz (except 13 and 14, and the 5GHz spectrum...

    Great working, easy to use router for $100 or less

    Before wasting money on a new router, look up the model of your old router and see if it supports DD-WRT. Many routers ship with atrociously bad firmware, and installing DD-WRT will fix all those issues immediately.

    Wireless file transfer speed SO slow...

    1) open a web browser to 192.168.0.1 (or whatever the IP address of your router is) 2) enter your username and password, if required 3) find the settings page for wifi 4) change the wifi channel 5) click "apply" 6) wait a minute 7) reconnect your laptop 8) if it still doesn't work, repeat...

    Wireless file transfer speed SO slow...

    1) Try moving the laptop closer to the router to see what effect that has on speed. If moving a lot closer gives a huge speed increase, then you've probably got a signal problem. 2) Try other channels. If your speed and ping are as terrible as you say, chances are that there's another wifi...

    Internet Policy

    If you're not up to configuring a RADIUS server yourself, the guys at the DD-WRT forums can probably help you. (Anandtech might not be the best place to ask.) BTW, the RADIUS server does NOT have to be on your network. It can be a remote server hosted by someone else, which would be quite a...

    WIFI adapter

    You tried moving the computers closer to the router, right? Most USB adapters have terrible signal strength, so if you're too far away, you won't be able to get good speeds. If you can get full speed when the USB adapter and the router are right next to each other, it's probably a signal issue...

    Advice to bypass Uverse for Wireless

    Again, no. You said to turn off DHCP. I said to turn off NAT and DHCP, then change the IP address. You left out two very important steps, and while the method you proposed might work in practice (kinda sorta just barely), it will also result in a network with a lot of malfunctions and quirks...

    I've never done this myself, but you can do this with RADIUS. DD-WRT has built-in support for RADIUS authentication, but you'll still need a separate authentication server.

    Advice to bypass Uverse for Wireless

    No. If you do this, you'll end up with either a double NAT or an IP address conflict or possibly both. The correct way to add a second router to a network as a wireless access point (and NOT as an Internet gateway) is to disable NAT on the second router, change the second router's IP address...
