 | There are a LOT of errors in this code. Look at it analytically, refactor it, and reflect upon what you are doing. I could point to at least a half-dozen serious issues, but that wouldn't help you learn from your mistakes.  |
| | And this question is in Software Development because?  |
| | Have you communicated with your domain registrar about this? |
| | Re: Networking You only want one router per subnet. Most can be configured for some number of dhcp (dynamically assigned addresses) as well as some number of static local addresses. If you need more dhcp addresses, then reduce the number of static addresses (while making sure you don't need them for things … |
 | How did you delete them?  |
 | Definitely, running an ARM emulator on an x86 box will be slow. Since Android code is just Java using the Dalvik compiler and bit-code interpretor, using an Intel Android emulator will work must faster (or should anyway). Your code should be directly transferable to an ARM system for hardware testing.  |
| | Re: C++ You are missing a right-curly-brace { before the start of your G_master class. Try this instead: class G_master { public: int m_secret; int m_guess; int m_win; int m_prev_delta; void setup(); void hello() { cout << "Hello\n"; } void listen(); void respond(); void menu(); int endchk(); void prompt(); void cleanup(); void … |
 | Designing a strong hash function is a hard encryption problem. Verifying your own work is futile and usually wrong. Read Bruce Schneier's Applied Cryptography. Until you do, don't even think for a second that your work is "secure". I have written and adapted hashing functions in my work over the … |
| | Re: Django Trouble It looks like you are trying to access a member of a class that is not declared or instantiated in instances of that class. You need to look at the "module" components and class/structure definitions. |
| | Re: password If it is the BIOS password, there is a means to reset the BIOS flash memory, erasing the old password, but it will require removing the cover and keyboard, and then shorting out a couple of contacts on the motherboard. My grandson knows how to do this, but I haven't … |
| | Neither. Study open sourced systems such as Linux and BSD Unix (which OSX is based upon).  |
| | Simple. Outer loop == n iterations. Inner loop == m iterations. Total iterations? n * m. It really is not a complexity problem since the problem is linear. |
| | So, is this hardware going to be open sourced? Or will it still be proprietary, requiring custom device drivers and OS versions? |
| | Try `split_string(line, strlen(line)+1, &strings_line_tokens[0]);`  |
 | Flash itself is being deprecated in favor of HTML5 for video applications. As you should know, PHP is server-side code whereas javascript, etc are client-side tools. If you want this to be a client-server application, then use PHP on the server to build/send javascript, jquery and such as strings to … |
| | And BTW, a stack overflow like this is a perfect attack vector for malware!  |
| | And your problem is? What is the forward slash in the "find" command? You are specifying the BEL directory with the find command. The slash is extraneous and may cause a parsing error, unless you have multiple directories at the same level that start with BEL.  |
| | This is often caused by glitchy sensors. If cleaning and reinstalling drivers doesn't work, try replaing the device. Mine sometimes just stops for a minute. No random movements though, thankfully. That would drive me nuts! It's fully optical, with radio connection to the USB bus (along with keyboard), so there … |
| | Simple. A strip of black electrical tape will deal with that nicely! The microphone is another matter... :-) Speaking from the department of paranoics department... |
 | Neural network programming isn't simple. It is the keystone of adaptive systems software. What text books have you read yet? If none, then get started with your studies! FWIW, I took an advanced neural network programming class given by the US Air Force at Hanscomb AFB (in conjuction with MIT) …  |

 | Re: Laptop You can also try configuring your power settings to only speed up the cpu and RAM when needed for processing purposes, throttling it down when not necessary. This will usually help control system temperatures. Don't set it on maximum continual power.  |
| | Re: pseudo code Pseudocode is a textual or semi-functional description of code to solve a problem. So if, the C code were `for (int i == 0; i < 10; i++)...` the pseudocode would be something like > for i = 0 while i is less than 10 then increment i and do …  |
 | This is actually quite simple. Boot from a Linux DVD/CD drive. Use the dd command to copy the system disc image to an external drive, such as: dd if=/dev/sda of=/externaldrive/osx-image bs=1M. This says, copy /dev/sda to /externaldrive/osx-image in 1MB chunks. You can also pipe that through a compression tool such … |
 | Re: Computer issues Good work! Now, you need to scan for viruses. This sort of thing doesn't happen with Win7 unless there is something bogus going on! |
| | Do you have other radios on the farm that might interfer with the frequencies that the access point and laptop use (2.4GHz and 5GHz)? If you are using 2.4GHz, and your gear supports 5GHz, you might want to try the higher frequency, though distance will suffer. Since you say that … |
 | For an iPhone, if you want to reduce your data footprint, then try Opera's mini browser. It is a proxy browser. Their servers do the fetching and rendering, and only send paint commands to your phone, significantly reducing the amount of data that your phone uses for web browsing. I'd …  |
| | Re: Java Language, or API's? Your question says you haven't researched this much. For video, there are a number, both closed-source (mpeg) and open source (mkv). For images, ditto - jpeg (closed source), png (open source). There are tools in many computing languages from C -> C++ -> Java -> Python -> … |
| | Time to take it to the repair shop if you cannot even boot into the BIOS. |
| | Go to the Services page in the Control Panel and see if the spooler is listed there. If it is running then try to restart it. If not running, then start it and click on the autostart icon so it will start on next reboot of the OS. If it …  |
 | I used to need to futz with the registry in XP on a regular basis. Don't run Windows any longer (occasionally in a VM, but last time was probably 6-12 months ago), so it isn't on my radar. All that aside, I just took a position with Panasonic as a … |
| | You don't need to post ALL of your code. Most of us don't have the time to read through it all. The error says enough. You are trying to access a member function without going through an instance of the object class where it is defined. IE, if method xyzzy() … |
 | There is a great book by Niklaus Wirth (the inventor of Pascal and Modula programming languages) called "Algorithms + Data Structures = Programs". This is one of the bibles of software engineering. My copy is from the 1980's, but it has been revised and updated a number of times since …  |
 | Sorry, but we do not do your homework for you. Make an honest attempt, post the code here along with errors or issues you are getting, and then we may help. |
| | Re: programming To put it a bit more simply (or at least less succinctly) than debastian did (which was absolutely correct) is that open source software (and hardware) is not proprietary and can be viewed or modified by anyone without cost. That doesn't mean it is not protected by copyright, but the … |
| | What do you mean by "adobe virus"? Yes, there are vulnerabilities in Adobe software, as there are in all software, though their Flash video player is one of the most exploited since so many people and tools are reliant on it. Is that what you mean? Do be more explicit. |
| | This is not uncommon when reading analog data like this. You need to filter out most of the input. There are a number of methods to do this, from simple (which is where you want to start) to complex such as using Kalman filters (non-trivial engineering stuff). So the simple … |
 | Boot into the BIOS and check the UEFI settings. Windows 10 probably requires secure boot to be enabled. |
| | Re: BNF Grammar You need to do some studying. BNF stands for Backus-Naur Form which is an abstract representation of complex processes and languages. Here is the Wikipedia article about it: https://en.wikipedia.org/wiki/Backus%E2%80%93Naur_Form As an example, the United States Department of Defense (in conjunction with Bolt, Beranek, and Newman in Cambridge Massachusetts) developed TCP/IP … |
| | Do you have to use SQL? First, solve the problem mathematically using an arbitrary reference point (latitude and longitude). Compute what the L&L (latitude and longitude) would be for a distance of 5km from the reference point in any direction. Then, you will understand how to derive that from database …  |
| | Your PHP restart script may need to specify a valid IP address, such as localhost (127.0.0.1:80). 0.0.0.0:80 is not a valid IP address. FWIW, the :80 part is the port that PHP will be listening on. Also, port 80 is the default for http (web services), and that may be …  |
| | Most of the time, the manufacturer will honor the warranty, but you will be responsible for shipping it to their factory repair depot. Go online to the manufacturer's web site and check with their support staff about that. |
| | What operating system and browser(s) are you using? Did you perform a recent system update? What anti-virus software are you using, and have you scanned your system for viruses? |
| | Describe your operating system, how the flash drive is connected, what device ID (letter for Windows or /dev id for Linux/Unix) it should use, and whether or not you disconnected it safely the last time you could access your files, or did the system crash, you disconnected it without unmounting … |
 | Assuming that the new power supply provides at least the same current rating and voltage of the old one, and has a compatible connector, then you should be ok. You definitely DO NOT want to use it if the current rating is lower than the old power supply, otherwise you … |
| | What exactly do you mean? Are you asking if future Windows updates will affect the functioning of VMWare images? The answer to that would be probably, but VMWare will quickly (possibly before the Windows release was issued by Microsoft) fix the VM host software to deal with that I would … |
| | ddanbe is being nice. We don't do your homework for you - please read this site's terms of service. Make an honest attempt to solve the problem. Write the code. Post the code and problems, error messages, etc here and then we can help you. |
| | How is the image being stored in the database? Subsequent reads of a fingerprint will not exactly match previous ones, such as that stored in the database. Fingerprint readers will look for a correlate major features (ridges, etc) to generate a match using statistical processes. I would assume the FPVerification … |
| | Apparently a bunch of other banks (last I saw was at least 9 total) have been hit as well. Some think this is a Russian attempt at retaliation for recent Ukraine-related sanctions. |
| | Sorry, but we don't do your homework for you. Make a good-faith effort to solve the problem, post the code you are having trouble with here, and then we can possibly point out where your mistakes are. |
The End.
