I haven't paid for the internet since I moved to my current apartment, since at any given time there are several dozen visible wifi networks, of which two or three are generally unprotected. However, recently, the most reliable of these (good old linksys) has disappeared. Maybe its owner moved away, I don't know. Anyway, my home internet is very spotty now, and I often can't get a signal at all. I need ideas, either home remedies or buyable gadgets, to boost my reception. Personal experience is preferable, ridiculous suggestions are acceptable.

Hi all Who knows anything to do with fractals in Dr. Scheme because I'm having a hard time making these damn fractals.

Hi, I really would like to obtain, the codes the algorithm in matlab for this method of signal processing : "Kalman-Filtering Speech Enhancement Method Based on a Voiced-Unvoiced Speech Model". Does any one know how I can find them? Thank you Laure

Concurrency is perhaps the foremost issue today's programmers must learn to cope with. CPU designers have exhausted the level of optimization they can provide to programmers working with a single thread of execution, and more modern designs take transistors which would've ordinarily gone to improve sequential performance and have instead thrown it at more cores. Intel demoed a CPU with 80 cores, yet one third of the transistors seen in a Core 2 Duo. This is the future of processors: more cores that do less. CPU designers are going to devote fewer transistors to each individual core while trying to pack more and more cores onto a single chip. Some crazy people are predicti…

Is anybody planning on beta testing this? I'd be interested to hear how it's looking. http://news.bbc.co.uk/2/hi/technology/7825111.stm

how does boolean logic such as and gate ,or gate etc. generate comlicated circuitry.please tell me a website where i can see a diagram of a complicated circuit and explanation of how it acheives its task.

Is anyone able to pull up hackerslab.org? (For those who are unaware: it's a site designed to be ethically hacked, created by a retired police officer to busy curious minds--and a redesign of the home page is encouraged when you complete the final level!) I can't figure out why I can't pull up the site. Does it still exist?

can anyone give help me in designing a archiving service for long term preservation of digital data.. being trusted it has to hav confidentiality integrity and availability.. i need some help as i dont hav any idea watsoever on this.. need ideas for implementation too.. pls help..

I've been all over the net looking for some help. I recently transfered encrypted data using winzip,from my old Windows XP to my new Windows Vista. I'm unable to open them in Vista.The file extension is an .xef file. What can be done to access these files?

Microsoft has released Seadragon for the iPhone. Seadragon is the core technology behind Microsoft's Photosynth application, which allows users to construct clouds of imagery and other data and then navigate them much like Google Maps. The iPhone app basically applies the same concept in a mobile environment, leveraging the multitouch screen. There's a video here showing it in action: http://livelabs.com/blog/seadragon-goes-mobile/ It's an interesting idea, and it's also making waves in the Microsoft community because it's an awkward acknowledgment that the Windows Mobile OS isn't up to this sort of thing.

are there any free programs for Linux that could be used to design something (an aircraft for example) and to test the aerodynamics of it?

So, Google's making a web browser. They took the Webkit rendering engine (often touted as the fastest around, and by far the simplest given its standards support) and built a multiprocess browser, such that every tab is contained within its own process. And they wrote their own JavaScript virtual machine (called J8) to boot. Sounds pretty spiffy...

Hello all, I need someone that can help me create a relatively simple web based application to demonstrate a certain science concept. In general, the app should present a physical situation (like oscillation, for example) and adjust the movements according to preset formulas. I will provide all formulas, I just need someone who knows how to apply this to a fully functional web app. I can't pay, but I you *WILL* recieve full credit on the site this will be presented on. We can sort details in private conversation. Contact me as a reply here, or by pvtmsg. PLEASE -- only only only if you know what you're doing. I know what I want, and I know it's not ha…

Hello, Okay, as a highschooler who is possibly looking to go into a career and a degree in computer science, can anyone just give me an explanation what someone in that area might do? I'm farely new to this so even the basics are welcome; I just would like to know what I will be getting into before I actually get into it. Any help is encouraged so please talk away. Thanks for all your help.

There appears to be a clear problem with these proofs. A halting machine attempting to operate upon itself would cease it's normal function and simply always loop. A function which gives 0 if the input function is defined would cease it's normal function and always loop if operated upon itself. The simple reasoning for this is either of these actions would cause an infinite regress whereas normally an infinite regress of this type would not occur... So these two functions could work fine on everything else, but then if they were operated on themselves they would not work. Every Halting problem undecidability proof asks us to assume that such functions …

You guys are some wacky smart people, what technical certifications have you accumulated over the years? My workplace encourages (and almost demands) that you constantly study for and get certified for different things, and will even pay for most! But I stopped going for those things years ago - if you have any secrets to studying, let me know! There's a trainer at my workplace with a good 16 or 17, what a jerk!

http://www.download.com/8301-2007_4-10042127-12.html Should be interesting to see how this plays out. The guy wrote an app for the iPhone that does podcasting better than Apple's app. So Apple is denying him the right to distribute it to iPhone owners. That fact alone should send chills up the spine of any programmer, but it gets better. Apparently the guy's distributing the app anyway, through some sort of back channel, asking for PayPal donations. But Apple has the ability to disable applications on people's iPhones remotely, so people are saying Apple will simply turn the guy off. Wow. If Microsoft did something like that the entire world would be in…

Hey guys, I remember I had a webcam software that could double-up as a "surveillance" software. Essentially, it reacted to changes in the picture so if you hooked your cam to look at your room while you were out, it would idle harmlessly until someone opened the door, or turned on the lights, or just walked around, and then it would take rapid-succession pictures (you could define how many in a certain period of time) and could either upload to FTP or send you an email alerting you that there was a change. I don't remember where I got this software from, all I remember is that it was a webcam software and that it was free, or at least that most features of it were…

Don't know whether anyones familar with rate monotonic and scheduling of real time systems, but here it goes: Task A (Period = 10 msec, CPU time = 2 msec) Task B (100, 6) Task C (250, 11) Task D (500, 5) Task E (250, 15) Task F (100, 6) Task G (500, 5) Task H (1000, 20) Task I (2000, 15) Question: During the actual operation of the system the driver may press the brake pedal at most 4 times per second. Pressing the pedal turns the system off. This process requires a worst case of 35 msec of cpu time and must respond within 90msec. Explain how you would incorporate this process into the above model. IS THIS A MATTER OF:- THE 4 TIMES PER SECOND IS THE PE…

hello anyone here know any good links for learning the VBS computer language.

i was working on a project. #include<iostream.h> #include<conio.h> void main() { int date(); int d; int data; cout<<"enter the date"; cin>>d; data=date(); getch(); } date(int d) { static int f=1; if(d>31) { cout<<"enter a valid date"; date(d); } return f; } please help me run this program.

Hi. I know about computer programming, but I'm not expert in Math. I know Computer Graphics is all made with Math. Can you tell me what kind of Math should I study to be able to make something like this? http://picturetopeople.blogspot.com Thanks in advance, Mark.

Hi, Computers have been used to analyse several geographical factors(in my case I need to measure ndvi index to measure plant growth.) Can anybody help me out .how is GIS used .Are there any alternatives to using GIS .And does anyone know any GIS information repositories. (I program in java,so would appreciate it if the replies would use this language) I know this is a more ecology topic but I anyone could offer a better( yet simple) way of estimating plant growth in a region, I would would be thankfull.
