Computer to Computer AirPort networks not accessible
I'm a Mac newbie, but I have lots of experience with Linux and Windows. I have got my AirPort-enabled iBook G4 working fine with my office network which uses a hardware base station. However, I can't get it to talk to my home network which has an ad-hoc (IBSS) network running on a Linux gateway machine. When I click on the AirPort icon, "Computer to Computer Networks" is greyed out. It used to work fine with my Linux laptop. I am using the same WEP key on the home network as on the office network. I don't have any weird settings except for using channel 8 (on both networks). Any ideas? Please cc your followups by email if that's convenient. TIA. ...

Computer to Computer chat
Hello, I have just started understanding WinSock and I'm wondering how to make a program talk to another computer through the internet? I have the other's IP address, though both computers are on networks (I couldn't seem to get any example codes to work with my computer, I think it was because of the router...) I know the port that I will be talking through and listening on. I just want this program to send simple messages that will be understood on the other side. i.e let p! = program 1 let P2 = program 2 P1 -> P2: msg = TALK P2 -> P1: msg = CONFIRM P1 -> P2...

Help with File Sharing via Airport Computer-to-Computer Network
Via Airport cards (and v3.1 of the Airport software) in my G4 and iBook (both OS X 10.2.6) I can create and have both connected to a computer-to-computer network. I have personal file sharing on on both computers, but can't seem to connect from one to the other. When I try to connect, they only see their own shared file server, which isn't much help. When I try to type in the address ala afp://g4.local/ ('g4' is the computer name) I get an "5000 Error". Via Rendezvous, although the network seems to be active I'm unable to get an iChat session going between the two...

Can't share files over computer-to-computer Airport connection?
I'm trying to set up file sharing between two Macs via Airport. I have no base station, but on the iMac I created an Airport network, and connected my Powerbook to the network (at least, the Airport icon on both show as connected, and both show the same network name and checkmark in the Airport menu). I have Use Appletalk set on the Airport configuration of both, and TCP/IP is enabled on Airport on both computers. Unfortunately, when I try to browse the network, the iMac does not show up in the Powerbook's Network. I'm at a loss as to why a published Mac can't be seen over a valid network connection via Airport. What steps am I missing, what other configuration items have to be set up for computer-to-computer file sharing to work over Airport? Thanks in advance (Why isn't this in a FAQ somewhere?)

Computer Problem
I know this isn't a programing questions....but it is hindering me from programming. I just bought a new monitor last night. Plugged it in and every thing worked for a while. I was able to play games and watch Video for about a 1/2 then the screen went blank and said it was going into power saver mode(just the screen). I rebooted it and went into windows but the log on screen was all a messed up image and then the monitor went into power saver mode again. I updated the Drivers for both the video card and monitor there aren't any bios updates that I saw for the card. when booting int...

Computational Mathematics and Computer Science
Hi. I'm trying to decide between colleges and one of the schools on my list doesn't offer a major in computer science (although a minor is offered) but offers a major in 'Computational Mathematics'. Is COMPUTational Mathematics related anyhow with the more theoretical COMPUTer Science ? Is there any connection between these fields of study (besides the first six letters) ? Also, if I only have a minor in Computer Science is it still possible for me to apply to graduate school (Phd) for Computer Science ? How do admission officers at Universities see such people who major in on...

Problem with computer
Most of the time when trying to open any folder on the desktop my system locks up. If I can open the desktop folder then all folders under a desktop folder seem to work O.K. The desktop folders especially dont like the double click opening rather then the right click and then click open. Also, many times when a folder does open it does so only after it warns me that a DLL is missing and I click O.K. Help please!!!!! So . . . what operating system are you using?

Comments about Mac -- Rookie to Mac but Oldie to Computers
Hi all, When OSX was released a couple of years ago, I noticed all the Switch commercials on TV and on Apple's website. At that point I'd not touched a Mac since using the Mac Classics back in high school (early '90s), but being a Linux guy I thought it'd be interesting to check OSX out. The one major fault I saw in Pre OSX Mac's was a lack of a good command line, but that's no longer any issues with FreeBSD under Darwin. So last year when a friend of mine wanted to upgrade to a more powerful Mac, I took the opportunity to purchase his PowerMac G4 (dual 867/768 Mb/Ram). It had OSX Jaguar and few add-on apps. I toyed with it for a few weeks and basically threw it in a corner rarely using it. At that point I had ran Linux exclusively at home for about 3 years, and I was in love (for lack of a better work) with the Penguin :) About 6 weeks ago I left for a week vacation to return with a clanking HD on my Linux box. Data was okay since I have two HD's mirrored for data, but the main boot drive (/dev/hda) was hosed. Instead of running to the trusty computer shop I normally use, I slid this box over and connected my Mac. The friend I bought it from still had some crap on the box, so using the restore disks I reinstalled Jaguar - and the love began. Jaguar installed perfectly, and within about an hour (after updates) I was up and running. Afterwards I downloaded Desktop Manager, Fire, and some other nifty utils from Versiontracker along with ...

Laptop Computer Furniture..(laptop computers)
laptop computers Laptops are small portable computers. They can be carried along, just like a small briefcase. They are convenient as they can be carried during travel. The furniture for this also has to be as per the dimensions of the laptop. With laptops being lighter and portable, the associated computer furniture is also becoming attractive and economical. A customer can choose from a variety of mobile laptop computer stands and desks. Some styles are foldable and perfect for travel. These laptop stands are good for small spaces. There are laptop computer desks to hold laptops, which can be rolled up to the conference room or to the bedside. Seat mounted desks are the perfect mobile organizer, for a laptop. They can be attached onto car seats. This enables the person to work even while being driven. Lap desks are very convenient and create a convenient work- table, wherever he sits. It costs around $99.00. Laptop caddy is a modification to the desks. This adjusts and tilts, so that the user can work anywhere in comfort. It is priced at $149.00. There are specially designed file compartments, which provide easy access to files and documents. This furniture is without a drill base mount, which is fully adjustable and removable in seconds. Adjustable laptop visor is another such accessory. It is adjustable to fit any laptop computer screen. It prevents glare and provides privacy. It is responsible for increasing productivity by reducing eyestrain and also protects the la...

Second computation longer than first (same) computation
Hi, Background : I want to compute cross correlation of an array. My first idea : loops over row then line, each time I have to circshift, and average, etc. It takes ages because of nested loops : for an image of 200x200pix, it takes ~10 seconds. So I want to remove the nested loops. I first create all the circshifts at once. All right, that's the background. Now I have a weird problem about manipulating (very) large arrays. Here is the code. tic L=20 N=120 M=-L:L; A=repmat(rude((N)*ones(1,2*L+1),M'),(2*L+1)*N,1); B=repmat(rude((N)*ones(2*L+1,1),M')',1,(2*L+1)*N); idx_lines=repmat((1:N)',(2*L+1),N*(2*L+1)); idx_rows=repmat((1:N),N*(2*L+1),(2*L+1)); new_A=rem(idx_lines-A-1+N,N)+1; new_B=rem(idx_rows-B-1,N)+1; toc; (rude is from here : http://www.mathworks.com/matlabcentral/fileexchange/6436-rude-a-pedestrian-run-length-decoder-encoder) It works pretty well. The problem is that for large arrays (it creates 5000x5000 arrays if L=20 and N=120) it takes up to ~100sec. If I repeat the same code, it takes ~10sec. If I repeat again, it takes ~1sec. Then the computation time remains the same, ~1sec. How to explain that ? The first time, all the steps take ~10sec. It's not one step that is stopping the computation. Is it an allocation memory issue ? I tried to pre-allocate the variables, it doesn't change anything. How can I solve this weird issue ? Thanks for your help ! "maxime" wrote in message &...
