Social networking will not kill email, for the simple reason that email is completely different. Sites like facebook are too playful for professional communication, and their security measures are far too easily circumvented (I'm too lazy to gather evidence of the insecurity of sites here, but remember when Twitter was …

Give an example of one of the forwards you tried to configure. People will be better able to help you if you do.

Wireless Internet is always a pain to get right. Look at tech specs for your computer and find out what kind of wireless card it has, then search Google for how to get it working with your card (you might be able to just search for how to get wireless …

Routers separate networks -- if you were to do this, you would technically have two different networks. While this is perfectly fine (especially if it suits your needs), a switch would work perfectly well. The entire purpose of a switch is to allow multiple devices simultaneous access to the network. …

you don't need to know the 65536 possible networks part (which is actually wrong, it would be 4096 -- I'll explain later), as the question doesn't care about that. All you have to know is that you need up to 14 hosts in each network. Each network has 2^n - …

remove the default gateway configuration from the router.

I would just like to add that 100 seeds is not necessarily "whopping" -- ubuntu desktop 11.04 currently has 600 and counting. Also, remember that those hundred(s) of seeds are uploading to all clients. Even if you're connected to 100 seeds, they're not necessarily all giving you their full upload …

Without CIDR, routers have to maintain a routing table entry for each destination network. If more than one of these entries has the same path, this is inefficient. With CIDR, a router can summarize multiple entries that use the same path into a single entry. Then, when it needs to …

Does the Internet work with a cable?

How about saving running-config to NVRAM? If it goes away when the interface goes down, I would be inclined to say that it's not a problem with saving to startup-config, but it might fix the restart issue. It would also help diagnose the problem to know whether or not this …

I am relatively new to perl, and I'm having a problem with loops. I'm trying to get a program for a simple number guessing game to repeat itself until you get the right number. Here is the code: [code] #!/usr/bin/perl -w $thinkingof = int(rand 10); print "Pick a number 0 …

I'm not certified yet, but I'm currently about halfway through CCNA II. I've found that the best way to study (for me) is to read the material, take notes, organize the notes so they make sense, then use the material. You see, Cisco pretty much takes the concept of summary …

Oh. Well, since you said plss... I don't know about you, but the last time I tried to build a network without a router, it didn't end very well.

Try [ICODE]sudo apt-get clean[/ICODE] and [ICODE]sudo apt-get autoremove[/ICODE].

I don't know the answer to your question, but I know what would really help someone who does: some code. Off the top of my head, though, I would guess that some sort of draw() function is being implemented each time the mouse is released. It's likely that this just …

Try a vaccine.

Try typing [ICODE]http://74.125.226.114[/ICODE] into the URL bar. The number is [url]www.google.com's[/url] IP address. What I'm thinking is that there may be something wrong with DNS (the protocol used to translate names like "google.com" into IP addresses that computers can understand) on your computer. By using the website's IP address rather …

"Empirical" means that the information was gathered by observation or experiment. This "conclusion" is reached with snarky quasi-mathematics. Valid or not, the claim that this proof is empirical is vastly incorrect.

I don't know about Windows (or Mac OS...), but if the machine is running Linux, there should be something in /proc that can help you. On my laptop (running Arch Linux) the files [ICODE]state[/ICODE] and [ICODE]info[/ICODE] in [ICODE]/proc/acpi/battery/BAT1[/ICODE] had pretty much all the information about the battery, including whether or …

What do you mean by "external access"? Do you want to SSH into a device or administer the network remotely? And if the address is already public, why do you need to "point" it at a local host? If the host has a public IP address, you can reach it …

I'm currently in the process of getting a CCNA certification (well, beginning to, anyway) and I'm starting to think about what kind of setup I should have to experiment with and observe network communications. Packet Tracer is useful, but it isn't meant to be a replacement for actual routers and …

A good tool to use is [URL="http://www.adobe.com/products/dreamweaver/"]Adobe Dreamweaver[/URL]; the downside is the fairly large price. You could also take some designs from [URL="http://www.oswd.org/"]Open Source Web Design[/URL] and modify them to suit your taste. There are some good Dreamweaver tutorials on [URL="http://tv.adobe.com/"]Adobe TV[/URL]

Which part of the program do you need help with?

okay, so I wrote a program in Perl to find prime numbers and, when learning C, I decided to translate it into C. The thing is that...well...it doesn't work. No matter what I do, I get the same message when I say ./primes.c at the terminal: Segmentation fault. I know …

Could it have anything to do with the fact that $smtpuser is not a valid email address? It's only the string 'myname'. The variable $fromemail is your email address.

My computer with Windows 7 on it crashed, and I need to reinstall. I have already backed up all the files that are necessary, but there are some programs (such as Spore and the Adobe Suite) that have DRM, such that I will not be able to fully install it …

Well, I want to have a program make a graph from the data that it has, so I looked up how to do that in Perl. The GD::Graph module came up. The problem is, that I tried installing GD previously and it did not work. I have tried every trick …

I have been using this code: [code="perl"] while (($key, $value) = each (%hash)) [/code] To iterate through a hash. However, the order of the keys that it retrieves are exactly the same each time i run the script. I looked to google for answers and found the following [URL="http://www.nntp.perl.org/group/perl.perl5.porters/2008/06/msg137802.html"]bug report[/URL]. …

Okay, so for the past week or so, I've been trying to set up a web server to...well...host a website. So I figured out how to install a LAMP server under Ubuntu and I got a free DNS hostname from dyndns.org. After configuring the router to use the dyndns hostname …

I have a Linksys WRT54G router for my home wireless network. However, I tried to flash it, but it bricked. How do I unbrick it? I searched Google and found a good tutorial to do this for the "WRT54G" but not for the version I have. Here's the [URL="http://www.thenorth.com/apblog4.nsf/0/668D65A56B02BB4B852570A400535F16"]tutorial[/URL]. I've …

Most CPU's in computers use x86. NASM and MASM and A86 are just different assemblers. If you've ever programmed in C, C++, Pascal, etc. before, it's like a compiler. There will be standard things on each one that will always work. The syntax for different assemblers should be pretty much …

Narue's tutorial is good, but [URL="http://tinyurl.com/d8dzp6"]this[/URL] should help too.

I'm having a problem with the substr function. I want it to be dynamic in a for loop as follows: [code="perl"] for ($i = substr $bin, $sub, 1 ; $sub < $len2 ; $sub++){ [/code] You can probably guess what this code is meant to do. I want to read …

Was your computer on during the storm? If it was on and not connected to a surge protector or power strip, then it's pretty much gone. I don't think this is the case, though, because your power supply clearly isn't fried. Although this doesn't always happen with power surges; it …

Okay, so I'm thinking of getting a simple wired router by Linksys or something just to practice some cisco networking things that I plan on learning a bit over the summer. You know, just some IOS practice and things like that. My questions is, which router should I get? I've …

First of all, you're not using any brackets ({ and }) with your loops. Note that the code for a while loop is [code] while (condition) { code goes here } [/code] The same goes for any conditional statement or loop where it executes more than one statement. Secondly, you …

Daniweb is pretty good with helping people write code, actually. You just need to do some work. Anyway, I don't know if this will help a ton, but here's an [URL="http://www.devarticles.com/c/a/Cplusplus/The-STL-String-Class/"]article[/URL] on STL

These are sort of simple, but here's what I've done (and a few things I want to do): 1. a command-line calculator 2. find the factorial of a number 3. Fibonacci sequence (# of iterations or max value input by user) 4. Binary/Hexadecimal/Octal to ASCII text converter (and vice versa) …

Hello, I'm just wondering how you would go about exporting the matches that regex finds. For example, if I were to have the following code, which matches all the digits in a string and (supposedly) reads them into an array, which is then displayed: [CODE] @numbers = ($string =~ /\d*/); …

I have a problem with a program I'm writing. It's supposed to find the factorial of the number you input, but it's not. The problem seems to be that the recursive function isn't...well...recursing. Right now, when compiled, the program multiplies the number by the number before it. So if it's …

Why are you taking a programming/computer science class if you don't want to put any effort into it?

I am writing a program that will take input and find whether or not the number you put in is prime. The program works fine, save for one small problem: [code] #include <iostream> using namespace std; int main(){ int num; //the chosen number int i; //potential factors do{ cout<<"Input a …

You need to download and install the perl interpreter. From the looks of things, you don't have it... [url]http://www.perl.com/download.csp[/url] To check if you do, just type "perl" into command prompt, and it will reply with a version number and some information. Anyway, to use the perl interpreter, put the script …

Is there any way that I can get PERL to give me the elapsed time that it took to calculate something? I'm trying to make my algorithm for finding prime numbers more efficient, and obviously I can't tell the differences in the time it took to generate the list, so …

I'm getting into bash shell scripting with Ubuntu 8.10, and the tutorial I'm using is telling me to open the file .bash_profile which is allegedly in the home directory. However, I cannot find this file, except in /usr/share/doc/adduser/examples/adduser.local.config.examples/skel and it's called "dot.bash_profile". Plus, the whole thing is just comments. The …

The characters you see are translated from the binary code. You could copy that text and translate it to binary... [url]http://www.paulschou.com/tools/xlate/[/url] ..and you'll get 8 digits of binary. For example, A is 01000001

Small programs usually run in command prompt...if you want it to have its own window, that's a different matter.

Is your Wi-Fi switch set to "ON" on this laptops?

Do you want this to just show the HTML for a website you made, or have it be an interactive thing were someone puts in HTML code on the left and the output shows up on the right?
