I have a Liebert GXT3-2000RT230 UPS, and just got a battery cabinet for it off ebay. Simple question: do I need to remove the load to connect the external batteries, or can I do it live? The manual mentions you can hotswap the internal batteries, but as I read it says nothing about the order...

I'm in the process of buying some 10GBe stuff to play around with, and I'm trying to get used gear off eBay so I don't have to spend a fortune to do so, but I'd like the option of buying recent equipment for some pieces. I bought a switch which has some 10G uplinks in the form of XFP slots, and...

I want to run a few Minecraft servers, each with its own set of mods. I have tunneled IPv6 connectivity, so I was planning on giving each server its own static IPv6 address and telling them to bind to that address on the standard port 25565. Then players who also have IPv6 connectivity can...

I'm interested in buying an HDMI-capable receiver for the purpose of playing video games. I have a projector which exhibits near-zero input lag, but the Pioneer VSX-1021K that I'm using adds something like 40ms of latency to audio signals that come through it, even in "direct" mode. Which AVR...

I have a Ceton 4-tuner card in my ESXi virtual environment. It's PCI passthrough-ed to an Ubuntu VM, which has the linux drivers installed. I have the following in my /etc/network/interfaces: $ cat /etc/network/interfaces # This file describes the network interfaces available on your system...

I have a 160GB PS3 slim that I'd like to sell. I have the composite (not component) and analog audio cable and the power cable, and I could find an HDMI cable to include with it. I have use for the controller, so if I sell you one, I'll have to go get another. $140 for the PS3 and whichever...

I have one 5870 eyefinity 6 edition, and they're on sale today. Should I get another, or hold out and get a 6000 series card (or a 7000 series card, for that matter)? Primary use is somewhat older games, but I'm considering going 2560x1600 (up from 1024x768 right now, lol) and more fps...

I've been running my own server for a while now, and its hardware is getting a little long in the tooth for what I'm trying to do with it. So I ordered some new hardware: Opteron 4170 2*8GB DDR3 ECC H8DCL However, before I put this new machine in production, I figure it'd be a good idea to try...

I'm looking for a cheap server power supply that I can use with a Supermicro H8DCL-iF and an Opteron 4170 and 16GB of 1.35V memory. I'll only have one laptop disk, and a USB stick in the system for storage. I'll only be using the system in this configuration for a few months, and then...

I'm looking for a solution to mount my fileserver and networking gear. I have: a 4u server a 1u switch a 1u patch panel a 2u UPS for a total of 8u ATM. I'd like to buy something at least 12U high to leave room for future expansion, and I'm trying to find something that could be mounted to...

I'd like to investigate creating a battery-backed 12V source for my server, so that I don't need to go up to 120AC and back down to 12V. I know how to go about building a regulated 12V source, and I can use my existing Enermax Revolution 1050 as a solid 12V source when the power's on, but the...

I'm in the market for an LSI-based controller using the SAS2008 chipset. The 9211-8I from LSI, the M1015 from IBM, the USAS2 from Supermicro, whatever. Solaris/FreeBSD compatibility is important, but any of those should be good to go. I found a place selling the M1015 for $150, so anything...

My machine at work has an nVidia GT330 connected to two Westinghouse L2410nm monitors. However, when I switch the displays off to go home, it apparently forgets about the secondary monitor. That is, when I switch the monitors back on, the primary display shows the unlock screen dialog, and the...

Hi guys, I'm looking at buying a DLP projector and replacing the bulb with an LED, and I want to figure out how feasible this is. I already have the LED (rated 6500lm at 100W), and I'm waiting on a lens to better focus it (right now it basically shines equally in every direction). Once I...

I have an Optoma HD65 that I got last August. Bulbs for it are rated for 3000 hours by the manufacturer. It came with a bulb that lasted for about 1000 over the course of 10 months. I figured, hey, sometimes you get a bad one, the next one will last a lot longer. So I bought a replacement...

I just bought a new box (Intel Atom 230-based) and I want to use it as a router. I'm using pfSense, which is easy to configure, but I'm getting lousy speeds through it. I currently have four interfaces on it: re0/re1 are pci-express Realtek 8111s, and bge0/1 are on a dual-port PCI-X card...

My computer has gone into some sort of coma. When I plug in power (and only power! no front-panel buttons, no USB, no video, no expansion cards, nothing) and turn the power supply on, it goes on for maybe half a second, then power cuts out again, and it loops like that. This machine worked...

I want to put the following cards into my machine, and need to find a motherboard that will hold them. LSI RAID controller: x4, 1 slot wide ATI TV tuner: x1, 1 slot wide Second tuner: x1, 1 slot wide Second video card: x16, 2 slots wide ATI HD4670: x16, 3 slots wide The ELA is only $50...

So there's new DLC out: "New" by No Doubt, and the whole Texas Flood album from Stevie Ray Vaughan and Double Trouble. I'm mostly a drummer of late, and the SRV stuff is boring in that regard. It'd be tremendously easy if it wasn't for the annoying left hand stuff in 2/3 of the songs ("Texas...

I'm writing a Python program that interfaces with a MySQL database using the standard MySQLdb interface. I construct a list of tuples like this: [(1L, 115L, 50, 50), (2L, 115L, 44, 44), (3L, 115L, 85, 85), (4L, 115L, 46, 46), (5L, 115L, 81, 81)] and then pass it to acursor.executemany(), like...

I'm writing a Python/Swig wrapper for some C code, and one of the things it does it take a callback function and use it to iterate over items. I want to properly wrap this: pass a Python callback function, and have some C code that translates the items that are iterated over into Python objects...

I'm in the market for a 8- or 16-port switch. Gigabit would be nice, I don't mind used, I like cheap, reliable, fast, and quiet in that order. I have no particular biases; anything that works well is okay with me. So, any suggestions?

I've noticed some wonkiness several times over the past few days, and was wondering if this is a known issue. 1) Quoting posts isn't working properly in many cases; I click "Quote" and it brings me to an empty post. The review of the thread below that shows posts several hours (days, even!)...

I tried to install Vista 64 on my machine, and it was taking (literally) ten minutes between each step. I don't think the hardware is at fault (it passes Memtest for 24 hours, and other OSes install fine: I installed Debian-amd64 in 40 minutes including download time), and I've tried two...

I have one new PM in my box, and it's not being marked as read no matter how many times I open it and read it. Also, the view in "Topic Review" when I go to make a post is several hours old. Is this a known issue?

I've got a program that is giving me back a nested list of the following form: [[[3, 4], [5, 6]], [[7, 8], [9, 0]], [[a, b], [c d]]] but to output the list I need to restructure it to have the following form: [[3, 4], [5, 6], [7, 8], [9, 0], [a, b], [c, d]] The innermost groups are what I...

At work we're buying new boxes. Using Sun's educational grant program, we're planning to buy five-ish boxes. Here's the list of parts available. We were going to go with the x4150 (middle build) without qualms until I noticed today that they have x2200 m2's available for less than half of the...

My power supply just died, and I need a replacement. I'm also planning to upgrade hardware within the next month, and planning to end up with a quad-core box, a Raptor, a couple gigs of ram, and eventually a 3870 x2 or whatever's good at the time I buy. Is the Corsair 750TX a good choice? Is...

I've got a laptop with an 855GM graphics controller in it. The machine has only 512 MB of memory, and xorg is allocating 128 of that to video memory. Here is a snippet from Xorg.0.log: (II) intel(0): I830CheckAvailableMemory: 448508 kB available (==) intel(0): VideoRam: 131072 KB I tried...

I've been disappointed with my laptop's speed since I got it. It's a Dell Latitude D400 few years old, and it has an Intel 855 chipset. There are two 256MB sticks in it. Today I ran Memtest on it, and it reported that the memory was clocked at DDR 266 (sounds right) and was transferring 279...

I'm looking to replace my aging CRT after Christmas, and have started doing my homework on LCDs. In that vein, I thought I'd ask for suggestions for what display fits my needs. Here are the criteria I've come up with: Mostly looking at 24" models, but bigger or smaller are okay as long as...

Chenbro is producing a standalone SAS expander which looks rather convenient - it fits in a standard PCI slot, and connects to the host and the drives. There's one version intended for occupying a system with a motherboard (it has two internal host connections, one external, and 4 disk) and one...

I'm (currently) using VLC to stream video over the Net (using HTTP transport) but I'd also like to capture the source material in higher quality than what gets broadcast (uncompressed would be just fine). Anyone have suggestions on how to do this with VLC, or some other software that can...

I'm looking to put a CF drive in my new laptop, and would like recommendations on which one to get. I don't care much for capacity - I plan to get a large secondary card for my home directory and so forth - but speed is my primary objective. 1 or 2 GB would be plenty, but if a 4GB card is...

I'm a fairly experienced programmer in a variety of languages, but I haven't had much need to interact with (or at least not much exposure to) SQL databases as yet. I have a test application I'd like to use SQL for (basically a price tracker over time), and I'd like some input on how to go...

I've got a very simple network that is nonetheless losing packets somewhere. I've got a Solaris 10 machine on one end, with a bge interface, and on the other end is a Linux 2.6.21.3 machine with a Realtek 8169. There's no switch in the middle, they're directly connected via crossover cable...

Hello all, We just migrated from lprng to cups here at work, and while most things are going well, we've had reports from users that when they send plain text through CUPS the margins are very, very small, so that the text ends up being written to an unprintable region of the page. Thus...

Thumbnails (if you can call them that... hand-nails, maybe?) link to cropped 5MP originals. Let me know if you want more. Hardware specs: Supermicro 370DER with 2*866 mHz p3s, 2GB ram 1*Fujitsu MHT2080BH, boot disk 2*120GB IDE disks, bleh 1*200GB sata disk 5*320GB Seagate ST3320620AS...

Hello all, I'm looking for a case to move my file server into. I'm using a Supermicro 370DER, which is just larger than 12x10, so it requires EATX support. I'm planning to move to a different board eventually, but I don't imagine a smaller board will suit my needs. EATX it is. Secondly...
