So i am trying to figure out how to build a battery charger that can recharge a battery pack containing lithium ion batteries in series totaling 7.2v 1760mA(contained in a flashlight - non removable). So far what i have done is taken a computer power supply, attached a few 4.1 ohm resistors(parallel) to it and threw it on the battery. So far this seems to be working.... but i feel the need to explore safer options, so i am asking here. How can i build a charger that will charge this battery pack? – Elliott (Talk| Cont) 04:03, 6 August 2011 (UTC)
http://en.wikipedia.org/wiki/Wikipedia:Reference_desk/Archives/Computing/2011_July_23#Sata_power_connector PSU has been replaced, and yet it still doesn't see the drives, nor do either of them spin up. The strange part is, I plugged in my own HD into it, and that's not recognized. And plugging in the new HD to my working computer doesn't work either. I'm completely out of ideas. Anyone know what's happening? KyuubiSeal ( talk) 04:21, 6 August 2011 (UTC)
(Foreword: Don't include Apple. Their products are historically overpriced, and they seem more fragile than glass tables. In fact, they seem to nickle-and-dime users more than Dell, if anything.
Also, a brand/manufacturer that you recommend should allow me to choose my own component parts; have a build-your-own-PC system like Dell's when I order one online.)
So, what brand/manufacturer would I be happier with? How so? -- 70.179.165.67 ( talk) 04:26, 6 August 2011 (UTC)
I don't care much for brands either because I was once in a situation like yours and a friend recommended Cyberpowers PC to me. I think this is going to sound like an ad but they really are good. I have been using them for the last decade or so and having bought maybe six desktops from them, I have only become more loyal with each purchase. They are simply the best. They allow all sorts of customizations and are pretty cheap. You tell them what you want. They put it together and ship it to you. The only single thing that ever went wrong was that on my last machine that I got, they messed up the power connectors on the motherboard and the machine wouldn't start...took me about an hour to figure it out and then fix it...and in all fairness it was probably because I got it rushed. Just google them and check them out. 174.29.65.10 ( talk) 06:21, 6 August 2011 (UTC)

I have a LAN using Novell Netware 4.2 and have 30 users. The software using for my business purpose is developed in Clipper 5.0 and run on DOS background. Two of the users are about one kilometer away from the server. The connection is established through lan extenders and a dedicated rented dataline from BSNL. But many often the connection get interrupted or the line become failure and the billing process at the two nodes became suspended. Hence I wish to know whether there is any other networking method available to connect the two distant nodes uninterrupted. Also I may ask whether any LANEXTENDER with wireless facility will solve the problem. Any kind of help to activate the two nodes is expected. — Preceding unsigned comment added by 117.241.57.149 ( talk) 09:24, 6 August 2011 (UTC)
Recently hacked data was released from various law enforcement agencies, [5] and the group responsible, Operation AntiSec, posted a lengthy hacklog of how it was done. [6] It makes for a very comical read, but not having up-to-date knowledge of computer security myself, I'm curious: does this log illustrate that the hackers were very smart, or that the law enforcement sites' security was very stupid? Is there someplace where this kind of message is taken apart piece by piece, line by line, and the errors (or exploits) explained so that any idiot can prevent this happening to their system (or take advantage of someone whose system hasn't been updated)? Oh yeah, and last but not least... they couldn't really "call release inmate () a few times" and have any success... right...? Wnt ( talk) 22:47, 6 August 2011 (UTC)
I'm trying to use some newly added functions from openssl that aren't available in the command line tool. My understanding is that the openssl libraries are accessible through an API itself that doesn't use the command line tool at all. Is that true? How does that interact with EVP ( http://www.openssl.org/docs/crypto/evp.html)? Finally, do the wrappers written in different languages need to define which functions they give access to, or are there libraries that give access to all of the openssl functions (for example if something was added very recently) without needing to know those functions explicitly?
