Ok. The neighbor whose wifi we've been glomming off of for the past year or so has moved away. (Don't you look at me so judgmentally. My rationale is that at this point an open network counts as an invitation to glom, in modern wifi etiquette.) There are a few other open networks nearby, but they are all weak and unreliable. There are also dozens of locked networks. One of these belongs to friends of ours, who live down the street. They're willing to share, which would be beneficial to both of us, because we'd split the cost. HOWEVER, this signal only comes in right next to the window closest to them. We'd like to be able to extend this such that our two lapt…

I followed a link to newscientist.com and got redirected to spam, don't know how exactly. Could a banner ad do that by itself? Just want someone to check the link, that can do it safely (in other words please make sure you're a computer expert ). Here's the path I took and the redirects according to my viewing history (on Firefox). I had gone to the Wikipedia link below and clicked on the footnote #11 link... http://en.wikipedia.org/wiki/Schrodinger%27s_cat 11. Chown, Marcus (2007-11-22). "Has observing the universe hastened its end?". New Scientist. Retrieved 2007-11-25. It began taking me to newscientist.com but (according to my history view) i…

Hey, you know how with PGP, the contents of the email are hashed, and then the hash is signed, and the signed hash is appended at the end of the email? That can be a lot of trouble, for large emails! You could be receiving a 50 megabyte email but you would be unable to tell that it was corrupted or not from someone you trust, until you had downloaded the whole entire email. What if you sent the signature part separate from the email? It contains the hash, encrypted with the sender's private key (and only decryptable with the sender's public key). Couldn't the recepient verify that signature, without having the 50 megabyte email at all? Sure you would only have the has…

I haven't searched thoroughly, so I apologize if I missed an existing thread... Can anyone give me an example of a differential equation used in computer science with a brief explanation? I'm working on a project that needs a specific example, but I don't know any yet, and a Google search failed to yield anything I could understand (I'm working with somewhat patchy first-year knowledge). Any help is appreciated. Thanks!

Hey people. I've got an exam tomorrow about algorithms and data structures, and in spite of my efforts I cannot find the answer to a question from the last exam (it is not at all uncommon for questions to be repeated, weirdly enough). So, the question is about Dijkstra's algorithm, and the implementation of the min-priority queue. I understand when to use an array (dense graphs), binary min-heaps (sparse graphs) and fibonacci-heaps, but I do NOT understand when it is reasonable to use an ORDERED array. Thanks a lot for any pointers or hints. Michael

Hello all I am wondering if anyone has any ideas or links to relevant material on any advances in peer to peer architectures? Mainly I am looking at Hybrid and Decentralised systems and if there are any areas these systems could be improved?? I am currently writing a report and my computer science skills are not the greatest so trying to find some modern techniques in this areathat i can actuall comprehend is proving difficult!! Any Help would be amazing!! Thanks Guys

Hello every one, I'm trying to make a list of the most recent computer terms, I mean the all the new terms that have been emerging thorough the last ten years, if anyone kept track of some or all them I would really appreciate if you could provide me with your list. Thank you. My email is twis_goss@yahoo.com

I have put many of my thoughts about OS design into this document. I appoligise in advance as some of the document contains OO programing jargon. Feedback is welcome. http://with-logic.co.uk/docs/TheOSProblem.docx

If any of you watch Ghost in the Shell, you will easily understand what i am talking about, if you don't i would advise either watching a few episodes, Ghost in the Shell Stand Alone Complex, or trying to dig deep. Ok, in the program there is a cyberspace connection between the persons mind and an avatar in cyberspace. my question is, if you were to be connected to a cyberspace and you were to be viewing lets say a video feed, would you see the video feed in a separate "workspace" aside from your vision? imagine your vision was similar to a desktop workspace, you can only have so many windows opened up. so i would assume that the video feed would be played similar to…

Hello, I tried to look for program that can convert 3D image in maya to C code. I have to find a program that can do that as fast as possible because I have to finish my thesis (which is a 3D paccman game in C language) in 5 mounths from now. Please, if anyone knows any programs that can do that, please give me a download link. It's really important. Thank you very much for all the helpers and your time, Ofir.

Every time I start up IE, I am getting a "security alert" message from Equifax. I have removed the certificate from my root certification options, but the alert still keeps popping up [even after I have restarted the computer]. Equifax is now not even showing in my certification list, but I still get the security warning every time. Any ideas please anyone? --------

Hello friends, I have a little question that "Is it possible to sync Microsoft Outlook with the iPhone?" Please suggest me the right way or provide the proper link if possible. Thank you in advance

I'm having an urge to buy a blu ray drive but prices are still a bit on the high side especially for burners, just wondering if it's wise to wait for the next generation of drives. I'm still not seeing any softwares or PC games out on blu-ray. And in general use it's still probably not common enough to warrant buying a Blu Ray burner. But the big advantage would be the ability to watch high definition blu ray movies on my pc. Anyway what kind of Optical drive are the rest of fallout using? Still with DVD or switched to blu ray?

hello everyone! im a computer science student, i have studied multiagent system and i have the idea of applying multiagent idea on operating system so it's behavior can be optimized via making each unit in OS as an agent collaborated with other agents to take there decisions according to there and others knowledge . and to take there decisions according the situation, and history. i want to apply this concept on part of linux , like on memory management part. my supervisor likes the idea.but i wonna know for how much i can apply it and what are the good tools can be used for? im studying multiagent systems now, what references i can use ? for details please che…

I am curious to if anyone has tried it out and what they think about it. I have to say it has some great features, but I am somewhat disappointed. Mostly because opera does not work really at all with flash in karmic.

I was recently working on a light sensing robot. Some how i managed to come up with it. I programed the robot with following program. I just wanted to know if there is some better way of doing the same, or is it fine when it comes on good programming. #define F_CPU 12000000UL // define cpu frequency for delay function #include <avr/io.h> // includes input/output header file #include <util/delay.h> // includes delay header file //#include"lcd.h" //#include"lcd.c" /* Program for Line follower */ //****************************************************************************** /* Connection of 3 PIN Sensor PORTs with atmega 8 PC4 Port is connect…

Can one make a website that gives full editorial control to someone, allowing them to upload content and make any kind of changes, but you still have a master key just in case you need to override that control? And if so, how possible is it to allow full control to either just one part of the website -- for example to the menu system, or images, or css scripts, etc -- or to just a certain number of functions -- such as permissions/access to one, two, or more server-side scripts (but not all of them), or even to particular functions of the server itself...like a person being able to update/edit/delete scripts yet has no control over their archiving into back-ups?* …

Hi ! i'm trying to get my head around this scenario i've come up with a class diagram but i'm not sure it's correct if anyone can have a look at it pls. N.B: my class diagram is attached aswell. SCENARIO: A local book shop that has approached you to build them a computerised stock control system and point of sale system. The shop sells a large number of books which are classified into genres: Non-Fiction (Science,Mathematics, Humanities, Languages, Arts), Science Fiction (SciFi, Steampunk, Apocalyptic, Time Travel), Crime Fiction (Legal, Spy, Whodunnit, Suspence) and Literary Fiction. Each book has a title (e.g. “The Hitchhikers Guide to the Galaxy”) …

I'm just kind of playing around with programming, I've gotten a relatively solid grasp on Java and eventually decided what I actually wanted to do with it. Then I realized that, for my program I need a database. SQL has been the best option so far, but I need to find out if I can make a view that doesn't refresh when its referenced tables are updated. Alternatively, if I could make a table that is based off of the values of another table (only at the time of creation), that would also be acceptable. The basic concept is to create a view that allows a user to see selected pieces of a table they don't normally have access to. Preferably, I'd like a specific procedur…

Does anyone have any good ideas on how to get passed a WGA on a WMP 11 i was going to try just a normal crack but no one is seeding anything for windows xp home... microsoft has come under the impression that my windows isn't genuine, hence the WGA problem, and now is forcing me to buy windows. My windows IS genuine.. my key is from Dell and i doubt that they fraud consumers. i have been using it for a long while wiht no problem.

So I'm just curious about how much math is needed in a computer science degree/and for programming in general. And how much advanced math do you need to know? I know it varies depending on what kind of programmer you are. So how much math would programmers in the video game industry require? Or people developing software/business applications? So far I've done good in math at school but I haven't really taken any hard courses so I don't really know how I'll fare with that.

Can anyone recommend a freeware free space wiper for Vista? Cheers
