 | Do you know any C++ or other object oriented languages such as Java or C#? If so, consider PHP to be C++ for the web: classes, methods, member and global/static variables as well as just-plain-functions. Most people make a hash of PHP, but if they program it like they would … |
 | OOP - classes + member variables + methods. Look at your code. What things could be expressed in classes? Zombies are one. There may be others.  |
 | You need an encrypt method that takes a list or array of files argument so it can encrypt each and put the output into the output file. |
 | Show your work such as what you are proposing for a database structure, how the tables are related, what are the primary and foreign keys, etc. We don't do your homework for you but will help once you have made some effort.  |
 | Re: php/mysqli You aren't making much sense. Please be more precise and complete in what you are trying to do, and how you are trying to do it. |
 | Generally, the timestamp field will not be updated unless the row has changed, update statement notwithstanding. IE, it is indicating when the row was physically updated. |
 | |
 | I see the return value, but nowhere do I see where you define the other servelet and from that call controller::processUser. |
 | Do you have a primary key or any unique keys defined for this table? If so, that is how you would do this deleting by primary key (unique) or another unique key.  |
 | Try using a live DVD instead of USB drive. That way, any faulty software on the live image can't break the media. Also, I am guessing that the ISO you built your live image from is faulty. Have you run a checksum on it and compared that to what is …  |
| | The PHP web site, www.php.net, has plenty of good tutorials. Check there first. |
 | Re: bank word Here's an alternative post: How plan for gobbledegook (hacker) network blank word? Ans: Ask Scoobydoo?  |
 | The software restriction policy is probably from Amazon. You should check with them. As a side note, NEVER buy music, videos, or software that encorporate DRM (Digital Restrictions Management). When you do that, you aren't purchasing it. You are simply renting it. They can remove your access to your content … |
 | What rproffitt is politely trying to say is that we do not do your homework for you. Make an effort. Show your code and where you are having problems. At that point, we may help you. Also, do read the terms of use of this site. It covers this.  |
 | This is a bad mixture of C and C++. Also, your main() function does nothing. First question is whether you are are supposed to be writing C or C++ code? If C++, then your structs for Graph and Edge should be classes and not structures. Yes, structs in C++ are …  |
 | What tinstaafl said. Compilers turn all variable names into symbols anyway. So using X vs. Games doesn't make any difference to the size or performance of your code, but it DOES make it a lot easier to debug!  |
 | Sorry. You do the coding. Then we can look at it and critique it. We don't give you the answers to your schoolwork. |
 | It depends is the correct answer I think. For systems with Intel processors, there is a built-in Intel GPU that these days is pretty good from the performance perspective. If you don't need the highest performance graphics (top-end gaming, video processing, etc) then a dedicated GPU such as an nVidia … |
 | Re: Student laptop I assume your boys have some of their own $$? If they need more RAM, let them buy it. However, for the CPU, go as high as you can afford. As pty said, an i7 isn't that much over the top. Also, forget about SSD drives. Too expensive and in … |
| | I think that you can consider the ? to be the same as 'then'. IE, 1.45, then E+1, ... Remember, E is the power of 10 that is applied to the number. So, 1.45E+1 == 14.5. Clear as mud yet? |
 | Assuming your system still sees the SSID of the WiFi accesspoint, then you will need to change your network (WiFi) configuration to use DHCP to get a network address from the local router. |
| | Never have had TWC. Verizon I had in the Boston Area about 10-12 years ago. I was one of their first FIOS subscribers. Here in Chicago we use AT&T, but only for phone and Internet. |
| | Look into the logrotate command and options. This is how we do it in enterprise systems. After the log file is rotated, you can copy it to backup media, to analyze at your leasure. Here is the relevant part of the logrotate man page: DESCRIPTION logrotate is designed to ease … |
| | As I have said to others, use logrotate. See the man page for logrotate and logrotate.conf usage. That will let you do exactly what you want. |

 | Samsung S7? They have bricked all of those phones because of the danger of the batteries exploding. |
 | Ask Microsoft? If they are going to send you a text message with a code to verify your account, it could take awhile. I have seen such things take up to a couple of hours. |
 | Download and install LibreOffice instead - open source (free) and can read/write MS Word (and other MS Office) documents quite nicely.  |
 | How are they connected. Also, are they routers, switches, or WiFi access points? If they are all routers, what are their base addresses? |
| | Have you forwarded port 5566 for the IP camera address (192.168.4.44)? |
 | Check your directory and file permissions. This is the most likely problem - incorrect permissions on sub-directories or for file access. |
 | Well, nobody here is going to analyze 5000+ lines of binary dump code. The first post indicating that a signal 11 (segfault) caused this problem is helpful. It means that the PHP code is either overwriting memory in the wrong places, or has run out of stack space, or has … |
| | Yeah. It would be interesting to see just how many viruses and trojans they can infect the system with. LOL. I too find these calls "entertaining" if I have the time. We have no Windows systems in our house. My wife is an iDevice user exclusively, and I am a …  |
 | Post a picture of one of the barcodes you are using.  |
| | I assume you tried other RSS feeds to be sure it wasn't a configuration issue? |
 | Ok. You have a question? Tell us something we don't already know... |
| | This is when I drop back to C and use realloc() - much easier and sets errno appropriately if you run out of heap (returning NULL for the result of the call). No copying necessary - realloc() will allocate the new memory and copy data as necessary. Programming C++ doesn't … |
| | Great question! I would think that the output to your speakers should work ok. Have you tried? Ok. I'm going to try my microphone as an input device like are using your cassette player. Hold on a few minutes. |
| | This could also be indicative of a hardware problem. See if the system vendor has a diagnostic program that can interrogate the hardware. Sometimes such can be found on the recovery partition.  |
 | I think that the failing yrange set [*:*] is failing because you are trying to set the yrange to infinity which gnuplot cannot handle. I'm not a gnuplot expert, so this is just a SWAG. |
| | Re: Recursion in C++ You will find some useful stuff in http://www.cplusplus.com/ If you plug "recursion" into their search bar you get a lot of articles that cover the subject.  |
 | Home and small business routers that incorporate a WiFi access point (most do these days) allow you to set the "channel" that the access point uses. For normal WiFi devices there are 12 channels, the default of which is usually 6. That said, since 6 is the default, the more …  |
 | Please show your altered code with the while() loop. One issue with your original code (which is what I assume you are showing here) is that it is infinitely recursive until "quit" is input. Eventually your stack will blow up. I suppose that is why you want a while() loop …  |
 | Re: Antivirus scan I think ClamAV/ClamWin have such api's. The key thing is that you need a signature for the virus you are scanning for. All A/V tools such as Clam have large databases of virus signatures that they scan for. I suggest Clam because it is fully open source and free. |

| | The graph looks ok to me, though there are some of what I would call irrelevant links, such as to the other cars the Naza distributorship handles. Does it matter? Can they handle more than 7 people, after all 1 husband + 2 wives + 7 kids == 10 people … |
 | Re: Any tips? > I am having trouble actually comprehending the syntax, for some reason I also have trouble applying what we are learning in our text book to the problems that we are assigned. Class::attributes::methods. For classes, think about things, like cars, animals, etc. For attributes, think about the things that make … |
 | Re: C++ Program > Can you please phrase the set of instructions in C++ compatible to my PC performance. They don't exist. Realtime is a kernel issue, not a compiler or CPU one. Utilizing 75% of your ram? Just allocate (operator new) as much memory as you want to utilize. However, this isn't … |
 | Each SQL database has its own connection api's and protocols, and they all have a connection api for the C language. You need to refer to the specific database documentation to determine how to do this. IE, MySQL is different from Postgres, is different from SQL Server (Sybase), is different … |
 | Please show your code performing this computation, and then we can possibly help you. We don't do your homework for you. |
The End.
