 | Call a web page? Do you mean render it as in a browser? Or do you mean to download it to your system? There are a number of commands to do the latter, such as the wget command: wget page-address  |
| | Here is a good description of the issue: http://www.cplusplus.com/forum/articles/416/ |
| | It is how compliant C compilers interpret backslash (escaped) characters in a string. Let's look at your printf string from a stringent C/C++ perspective: "\nab\bcd\ref" The "\n" should be translated to a new-line (CR/LF on Windows, and LF on Unix/Linux). This should drop the cursor down one line, to the … |
 | Depends upon the optimizer - both execute 100,000 assignments in the end. If the optimizer is good, it will detect that you are assigning x from y without any computation, so it would optimize out the loops and just assign y to x once.  |
 | Well, here is what I found: http://en.wikipedia.org/wiki/F%C3%BCrer's_algorithm http://www.cse.psu.edu/~furer/ http://www.cse.psu.edu/~furer/Papers/mult.pdf Have fun! :-) |
 | How is this connected to the system - sata, usb, ide? |
| | The sauce probably got into the system, shorting out the interface to the pad. You need to take the case apart and clean it up thoroughly. |
| | Don't ask us to do your homework! That said (and often before), do some research on in-fix, post-fix parsers. Do you want it to handle RPN (Reverse Polish Notation) expressions, or normal in-fix notation? If you can't answer that question, then you REALLY are behind the 8-ball! |
| | Re: title proposal 1. Make fewer laws. 2. Fishkill is a town in New York state. There is no solution! 3. Better marketing. IT solutions? Who the heck IS your professor/advisor? These are (in my opinion) totally bogus! I'm sure you can come up with some IT approaches to these problems, but why? |
| | Re: computer Agreeing with ddanbe 100%... If you have no clue now as to what you are interested in with regard to this field of study, then you should change your focus to something like marketing... |
| | Mostly crescendo is correct. To me, these terms are only relevant to the definitions of "hard" vs. "soft" computing that are in use by the propagator of the question. IE, you mean apple, and I mean orange when referring to fruit... |
| | Does it only freeze when running Windows, or also when running your Linux live cd? |
| | Along the lines of what JorgeM said. I used to do such work a long time ago, and still do occasionally on a consulting basis. I document the equipment, software, configurations, router settings, and run a network mapping program to map the lan and the connections between systems (netmap). FWIW, … |
| | Java is Java. Mobile, PC, server - it is all pretty much the same code. Android uses a version of Java called Dalvik - it is Java code, but with a different compiler and byte-code interpreter (virtual machine). That said, how you approach application development in each such environment is … |
| | Re: String Generate Jony, it seems that you keep asking us to solve your homework problems for you. We don't do that! Make an honest effort. Post your OWN code. Tell us where you are having difficulties with it. And THEN we might decide to help you. Unfortunately, you have not got off …  |
 | Does your laptop's network tool detect the SSID of your router? If the router's WiFi is secured, have you logged into it? |
| | We don't do your homework for you, which is what (in not so many words) Moschops was saying. Make an effort. Post your code. And if it is reasonable, we might decide to help you - though you haven't got off to a good start here...  |
 | My advice? Go for what gets your juices flowing! That can make a career. Anything else is just a job! Find that niche and get good at it. Get so good, that anyone who needs someone who is an expert in that subject will naturally gravitate toward you to help …  |
| | You just want to chart securities market moves during the day? Look into charting tools such as GNUplot. That would work very well, and you can tie it to a browser window using JavaScript very easily. In case you are insterested, I spent at different times about 4 years doing … |
 | In my opinion, this is a domain that has a new "cure" every other week! Personnaly, I don't GAS (Give A Sh!t) as long as it stays out of my way, lets me configure it to my needs, and works without my thinking about it. Most current GUIs are useless … |
 | Re: how to run? To both arpha16 and exsoft: we don't do people's homework here. If they post their best effort code and describe where they are having problems, we might help them. However, the terms of service for this forum is that we DO NOT do your homework for you! So exsoft, please … |

 | Frank, from what I (and others) have observed, you are obviously trying to help newbie C++ programmers with common patterns. Unfortunately, as folks such as decepticon and labdabeta have indicated, you may be causing more problems than you are curing. I applaud your efforts, but I encourage you to get … |
| | MPI - Message Passing Interface. The link that AD provided is very good. The US national laboratories publish a lot of computer science stuff that is extremely useful. I like the CS pages of Oakridge National Lab (http://www.phy.ornl.gov/csep/) myself (great stuff on semi-numerical algorithms, random numbers, Monte Carlo routines, Finite … |
| | Re: Viruses Pr0n and such are NOT the only source of viruses. These days, a lot of major web sites are from time to time infected with so-called "drive by" viruses - embedded in altered java script and other web pages. My approach is this: 1. Use a good virus scanner. 2. … |
| | Re: Bad at Math Basic math (including algebra) is critical for any science or engineering/computer-oriented career. I won't hire staff that doesn't have at least a good foundation up to a mid-level algebra, even for low-level positions. Even if you find it difficult, if you are motivated, you will find the resources that will … |
| | Assuming this system is 64-bit capable, then it should not be a problem. There are many 64-bit linux distributions you can download for free and install as you wish. FWIW, 1.5GB is not bad for many Linux distributions, but I would NOT want to run a 64-bit Windows system with …  |
 | Re: port forwarding You need to look that up with Steam for this game, or it may be configurable so you can set the port yourself, and then forward that. If the game only needs one outside-visible port, then the start-end points would be that one port. If the game can take both … |
 | You can install and configure a small Linux box as a firewall and blacklist filter. It will be considerably less expensive, both from the hardware and software perspective, than installing a Windows server to do this. There are also dedicated boxes, most of which internally run Linux. Try some Google … |
| | Re: /etc/fstab You might want to read the mount and mount.ext4 man pages for more information about the options available. Some may be useful to you. |
| | You probably just unplugged it and didn't unmount it or select "safely remove" option from the disc icon. That probably damaged the file system. It can probably be fixed. If you don't need the data on it, you can reformat it. If you do, then you will need to get … |
 | WiFi does not have such a range normally. In any case, you will need a number of bridges/repeaters. You can send from one repeater to another over a long distance using a Yagi-Uda directional antenna. I've used them in the past to bridge local WiFi transmitters over a distance of …  |
| | Re: Simple scan tool What operating system do you want to use? How you do this depends entirely upon the API's the OS provides. Windows systems will be totally different from Linux or Android systems. |
| | Sorry, but we don't do your homework for you! Post your approach to the problem, the techniques you would use to optimize the workload amongst the clients, and the math to apply to it. Then we may be able to help you find the errors of your ways... :-)  |
| | Re: discusion I've had this happen with one of my Dell laptops. It required a motherboard replacement on one occasion, and a disc drive replacement on another. If cleaning the vents and removing the dust from the motherboard doesn't deal with the situation, then more serious repairs are indicated.  |
| | Mike2K rocks! Thanks for the post Mike. I haven't pulled myself up to speed on the new standard. This helps, and I WILL do some dilligence on it... :-) |
| | Re: Merge Sort Please indent your code, otherwise it is VERY difficult to read! Example: int* merge (int *a,int *b) { int *arr; int i,k,j; int size= MAX1+MAX2; arr=(int *)malloc(sizeof(int)*size); for(i=0,j=0,k=0; k<size; k++) { if(a[i]<b[j]) { arr[k]=a[i]; i++; if (i==MAX1) { for (k++;j<MAX2;j++,k++) arr[k]=b[j]; } } else { arr[k]=b[j]; j++; if (j==MAX2) { … |
 | Are they obviously taken with your computer webcam, or are they from some other source? If you can tell from the backgrounds that your computer webcam was used, then you can assume you have been seriously hacked and someone is monitoring you, possibly in real time! |
| | DarkLightning7 is about 99% correct... :-) In reality, you need to understand context. When you call a member function of an object, inside that function, "this" refers to the object in context - that the function is operating on. Inside the constructor of SomeClass, "this" is no different than inside …  |
 | What stultuske said, plus this - the reason I don't use IDE's to generate code, java, c, c++, or other is that when I write code I want FULL CONTROL over what is going on - at least to the extent that the compiler allows me! So, I use make … |
| | There are a number of ways to do it. A good way to start is a live usb drive you create with the tool unetbootin: http://unetbootin.sourceforge.net/ That will create a live usb (bootable) drive without touching your computer disc drives. A 4GB thumb drive will do nicely. The other way …  |
 | Well, if you want some information about SH, go to the source: http://www.safenet-inc.com/ I don't know what app you are using that utilizes this bit of (in my opinion) malware, but you could try removing it from your system (add/remove software) and see what breaks... |
| | Re: OOPS Don't give short shrift to "bookish type knowledge". I was giving a paper at the OOPSLA conference in San Jose in 1996 and was in the meeting where Booch, Rumbaugh, and Jacobson announced that they were merging their different, but complimentary, object oriented design methods into a single form, UML, … |
 | Learning basic C/C++? Better to use GCC compilers and tools rather than MS ones - they are more "standard". You can install MingW or Cygwin on Windows, or a Linux virtual machine (with Virtualbox for example), and learn there. MS Visual Studio is specific to the Windows environment, and does … |
| | Have you installed the wxGTK, wxGTK-gl, and associated development packages? |
| | Re: /etc/init.d If you want a script or command to run at boot, but not be a service, then it is intended that you add it to the /etc/rc.local script. I do that to start openvpn connections on boot, for example. |
| | Also, look for it in /opt/sqldeveloper/bin, and make sure the shell script has been made executable. |
| | Processes are assigned "random" (sequential) pids by the operating system when started up. You can determine what PIDs are assigned to which processes with the 'ps' command and then use the 'kill pid' command to kill a specific process. You can also kill a specific named process with the 'killall … |
| | On my system, the 'transforms' command doesn't exist, so the output of this command is always '0'. I looked in all of my application repositories, and could not find it - even trying to install what I thought might be relevant packages. Still no luck! Anyway, let's look at the … |
| | What are you trying to do - 1. connect a Lumia phone to a Linux system, or 2. install Linux on your Lumia? FWIW, I am a senior Nokia engineer so I know a bit about these subjects! :-) |
The End.
