 | IPv6 addresses are generally represented in strings a a series of 5 16-bit hexadecimal values, separated by colons. The first hex number is separated from the rest by dual colons. There may also be a trailing subnet mask, such as /64. Example, my Linux system IPv6 address is (numbers changed …  |
 | Re: Pivot tables In Libre Office or Open Office, they are much the same as Excel. I don't know about Google Docs unless that is built upon Libre/Open Office tools. FWIW, Libre Office much more compatible with MS Office applications than is Open Office. They have expended a huge amount of resources on …  |
 | Any recent system will have USB 2.0 and/or 3.0 connections. What is your motherboard? If it is old, then you may be able to purchase a PCI usb hub to plug into the backplane. Until I know exactly what MB you have, then I cannot help any further than this …  |
 | When proprietary software is hacked, you are SOL in terms of fixing it since you do not have access to the source code. FOSS is not such, and since you can access the source code, you can analyze and fix it as necessary. So, in relative terms, Open Source software … |
 | Remove it. DO NOT OPEN IT! It may well be malware, ready to infect your system if you open it. I don't know, but as the saying goes, better safe than sorry! |
| | Sorry CimmerianX, but this is a college, not a company system/network. Such lockdowns for colleges is just, in my opinion, stupid! Some firewall protections and such make sense. Limiting the applications students can use is counter-productive. @Michael_35 - yes, a dual monitor KVM switch is pricey. I have one, so …  |
| | ClamAV is free, open source, and quite good. There are other options out there as well, but commercial ones that will cost you some $$. |
| | Do you know what an MVC is? That is an acronym for Model-View-Controller API. Understand that first, then look at the various API's that implement it, such as Spring, et al.  |
| | Re: C++ Help When does Easter Sunday occur? Easter celebrates the resurrection of Jesus Christ. The day of Easter falls on a Sunday based on the lunisolar calendar, not a fixed date on the Gregorian or Julian calendar. It has been determined to fall on the Sunday after the full moon that occurs … |
| | Windows systems since version 7 have not played nice with virtual machines, especially VirtualBox. Why? I think it is because they want to write data, such as the system ID, to the system BIOS Flash memory chip, which is not avilable on most virtual machines. This is one of the … |
| | Re: PC wont turn on So, the PC is not a laptop/portable unit? It started acting like this after a big rain storm? Is this correct? |
 | I will always be suspicious of vendor-written and distrubted programming languages. Lock-in is the least of the issues. Open standards exist for a reason. This is why I don't like Java - it isn't open, and sucks for a variety of reasons! |
| | Re: How to be ? That and two weeks I can make you an astrophysicist. Get real! This is not simple stuff, "give me all related things to the game developement"! Study, experiment, study some more, experiment some more, ... And to become an astrophysicist you need 4 years for a BS, 2 more for … |
| | Use a map, based upon the Name field. If the Name field is not unique, then use a multimap. |
| | You need to provide the context and code where you call NSUndoManager(). In any case, that error should point you in the right direction to fix this. |
| | Fastest way is for the factory to create maps of class names and ids to constructors for each. If you know the id (an integer of some sort - either 32 or 64 bit), then you don't have to interpret the string. |
 | This is how to do it: #include <stdio.h> int main(void) { int a = 10; int b = 12; a ^= b; b ^= a; a ^= b; printf("a == %d, b == %d\n", a, b); } |
| | Unfortunately, Windows hasn't always handled buffering of large amounts of data when reading/writing to external drives very well. You don't mention which verion of Windows you are using, but I would guess XP? Linux? Never had such a problem (I regularly read/write/copy/move 100's of gigabytes of data without issue). Windows? … |
| | No terminating semicolon? |
| | Also, I think that line 8 should just be `system.out.println(c);` The compiler will probably complain about the `(sum c)->` - it is non-terminated (no semicolon) and there isn't some value or method that the "pointer-to" operator references. |
| | I think you posted this question previously. What responses did you get?  |
 | Contact MS or the hardware vendor to see if you can get a copy of the key. The vendor may be the better bet since you can give them the serial number of the machine and they should (maybe, if you are lucky) be able to look it up in …  |
 | To continue on Moschops post, the only way to return multiple values from a function is to put them in a structure or object, and then return that. This will require modifying the signature of the function accordingly. |
 | Please do not double-post your questions. See my response on your other one and then delete this post. |
| | This is where your interests and imagination come into play. We can't tell you what to do, but we can advise you in regard to your choices. Hot buttons these days are web and mobile applications. Both big data and security are hot topics. Do some research on your areas … |
| | `for (int i = 0; i < terminatorvalue; i++) { do some stuff }` `while (somevalue < terminatorvalue) { do some stuff }` `do { some stuff } while (somevalue < terminatorvalue);` These are examples of C/C++ looping constructs. Alter to your needs. Then post your code for your class … |
| | Re: msoffice Are you the creator/owner of the document? Are you having problems starting Word, or is it accessing the contents of a document? Have you tried Libre Office? |
 | This is a case for a do ... while construct. Try this: #include <stdio.h> int main() { int n,count=0; do { printf("Enter an integer: "); scanf("%d", &n); if (n != 0) { n/=10; /* n=n/10 */ ++count; } } while (n != 0); printf("Number of digits: %d",count); } I also …  |
| | First, study AI for about 4 years at a college level. Next, learn CLIPS because an inference engine needs a rule engine to work. While you are doing that, learn to program in LISP and Prolog which are the two major AI programming languages. I have a nice shelf of …  |
| | As has been said numerous times before, we DO NOT do your homework for you! Make an effort to write the code, post it here, and we will consider helping you. |
 | You can't "fix" bad disc sectors. Most modern drives have the ability to map bad sectors to spare sectors, but once a disc starts to go bad, those get used up quickly and when you get an error like this all you can do is to backup all the data …  |
| | We don't do your homework for you. Your examples of $c_start are possible return values from C functions. Diff compares two files and outputs the differences between them. What EXACTLY are you trying to do? You say "extract C functions from diff output" basically. Show examples of what you are … |
| | Sorry, but we don't do your homework for you. Turbo-C is irrevalent here. Try to solve the problem, write the code, and when you are still having problems, post the code here. At that point, we may help you. |
| | Re: Recursion 1. We don't do your homework for you. 2. English is the preferred language for this site. 3. If this is Vietnamese or a similar south-east asian language, not many of us can read it. See #2. |
 | The disk read error at the bottom of you lising would indicate that the drive is starting to fail. You likely need to replace it asap, reinstall Windows on the new drive, and copy your data files to the new disk. |
 | Trying to recover a Windows disc with Windows is like trying to fix a broken window with a hammer! This is what I do (and have never been thwarted in this): 1. Boot a Linux Live CD/DVD 2. Attach a USB or other drive and mount it under linux. 3. … |
 | If you have a recovery partition, you may be able to fix it. In any case, you need to scan the disc for hardware failures (too many bad sectors). It may be that the disc itself is fubar (fouled up beyond all recovery). |
| | Good luck! I had a Seagate consumer external drive that died after a short while. I have found that these are usually manufacturing seconds, and are unreliable. Now, I only purchase "enterprise" external drives (no cases) with a 3 year warranty, and then put them in a case that I … |
| | Not really. WiFi is a radio link. You can connect your PC's ethernet port to a WiFi router, and that can then be accessed via wifi-enabled devices, but you still only have one WiFi access point. 2 points == 2 devices, etc. |
| | Go back, and read the book! In any case, I don't see where you have implemented f1D1 or f1D2, etc. Also, D1 is bogus since the argument 'a' is not defined as type and it isn't used in the function, and further b and c that are used there are … |
| | Also, please DO NOT post multiple copies of your issue. That is just bad and improper etiquete... |
| | Send it back as defective and insist on a new system. And whatever you do, DO NOT accept a "refurbished" system. You should get a brand new, unused system instead. Insist on that. Also, don't let your brother NEAR to the new system! |
| | As Shulc said, there are tools out there that will enable the installation of OSX on compatible x86 hardware, but bear in mind that there is a LOT of cruft that won't run because of their dependence upon hardware/firmware that is unique to Apple systems. I would suggest that you …  |
| | Read each line separately (see man page for getline), and then process the contents of the string read for the line. You really do not want to use fscanf() for this purpose. After you have read the line into a string buffer, you can sscanf() instead to read the contents … |

 | Can you tolerate lost data? If so, then you should use rsyslog to a networked stream. If not, log to a local file and have a daemon that uses inotify to learn when the log is updated, and that can stream the data to a remote system. From your code, … |
| | The file /etc/php.ini should be owned by root, and only root has access to it. If the permissions are not -rw-r----- then it is not correctly configured in the file system. IE, if correctly configured, users should not be able to alter the file and give themselves additional permissions other … |
| | You would most likely need to use assembly language to do this, but if you want to perform meaningful I/O, then you still need OS or BIOS support. IE, you might be able to invoke BIOS interrupts to do things like read/write bits to various I/O ports. This is what … |
| | FWIW, all ethernet interface ports (NIC - Network Interface Controller) have a MAC address. They don't need an IP address since they are only handling traffic at the transmission layer. As I mentioned above, it is the firmware (usually an FPGA or similar device) that deals with where (what MACs) … |
| | Re: excel In theory you can't, but the terms of service for this web site indicate that even if I knew how, I couldn't tell you anyway. Please search the web for this information. |
