  • What is a good "free-form" ("type anywhere" or canvas-like) text editor? [on hold]

    - by scorpiodawg
    My 5-1/2 y.o. son is starting to use a computer and one of the things he likes to do is to type stuff into an editor. He has used TuxPaint before and is familiar with the idea of a "canvas" for painting stuff (where painting anything anywhere on the canvas is fair game). When he opened the text editor (this was gedit on Qimo Linux), he attempted to do the same thing -- he pointed the text cursor to an arbitrary location within the editor window and expected to be able to type there (like a "text canvas", if you will). I had to explain to him that he would have to press Enter a few times to create new lines, as well as press Space a few times to create columns before he could do that. This is sub-optimal. My question: are there any free-form, canvas-like text editors that I can have him use? Almost like hex editors of yore. I am not interested in getting him to create "text areas" in a paint program.

  • Basic SDL2 Code which "Stop working" when calling SDL_Quit() [migrated]

    - by Rivten
    So I got into SDL2 with C++ quite recently and I did this very simple code : int main(int argc, char** argv) { SDL_Event *event; bool done = false; if(SDL_Init(SDL_INIT_VIDEO) != 0) { std::cerr << "Problèmes pour initialiser la SDL : " << SDL_GetError() << std::endl; return 1; } SDL_Window *window = 0; window = SDL_CreateWindow("Mopion", SDL_WINDOWPOS_UNDEFINED, SDL_WINDOWPOS_UNDEFINED, WIDTH, HEIGHT, SDL_WINDOW_SHOWN); if(window == 0) { done = true; } while(!done) { while(SDL_PollEvent(event)) { switch(event->type) { case SDL_QUIT: done = true; break; case SDL_KEYUP: if(event->key.keysym.sym == SDLK_q) { done = true; } break; default: break; } } } SDL_DestroyWindow(window); SDL_Quit(); return 0; } While that code executes at first quite well, when I hit the "Q" key, the window closes but I got a Windows Error Window saying that "My program stopped working." which is not very convenient. Using the debugger, I found that everything is fine until SDL_Quit() is called. Anyone has any idea why this is going on ? Thanks a lot !

  • Find visually similar images automatically?

    - by TERACytE
    I have a collection of images which is updated regularly that I'd like to group. Rather than reviewing every single image in the collection, I'd like to run an automated tool that pre-groups the images. Adobe PhotoShop Elements has a "Find Visually Similar photos" feature which works well, but it requires manually importing the images first, then I have to select an image each time I need Photoshop to search for images that are visually similar. I do not need a de-duping program since the images are never identical. Is there anything out there that can provide what I'm looking for?

  • Slow network file copy on Windows 7

    - by Jason V.
    I wrote a program that uses xcopy to transfer files (usually between 1KB and 2MB) over our intranet. Usually, I am copying files from my host machine (Windows 7 x64) to a VMWare virtual machine running Windows Server 2008 (the VM is running on my host machine, if that matters). On Windows XP, the file transfers usually only require a few seconds to complete. But on my Windows 7 machine, the transfer of the first file (1.5 MB) takes around 1.5 minutes to complete. This is true whether I use xcopy, robocopy, or programmatically using File.Copy(). I noticed that if I use File.Copy, the first transfer is very slow and subsequent transfers are much faster. Any clue how I can speed up the process? Is there a setting in Windows 7 (or server 2008) that I could try?

  • Timing startup processes?

    - by acidzombie24
    My Windows 7 use to boot up fast and now its getting rather slow. I suspect one program is eating up all the time yet i cant tell what it is since task manager shows <40% of the cpu being used. What can i use to track how long each process takes when my computer boots/starts up? Note: Except for launchy which i used before my comp became slow, all my startup and services are all signed and known (broadcom, VMWare, Google Inc, Intel, etc) Note2: I am mostly considering the time it takes after i login but i suspect the time before that is slightly slower (i dont think very much though)

  • Firefox: combine bookmarks toolbar and tabbar

    - by horsedrowner
    I am looking for a way to 'minify' the Firefox UI by combining the bookmarks toolbar with the tabbar. The easiest way I could see this done, is by simply moving the Bookmarks left of the tabs on the tabbar. I do not have the knowledge of writing my own userChrome.css styles, but it seems possible to do it this way. Another more difficult way to do this, would be by making it work similar to Windows 7's taskbar. What I mean by this, is to have a bookmark toolbar, and clicking on a bookmark would turn it into a tab, just like clicking an icon in the taskbar in Windows 7 would turn that into a 'program'. Ultimately, it comes down to this: by default, you have two toolbars: a bookmarks toolbar and a tabbar. I would like to combine these into one toolbar.

  • Monitoring/logging a malfunctioning internet connection

    - by Pekka
    I have a mysterious internet connection problem: Every 15-20 minutes, the connection will become very slow, and take 2-3 minutes for anything to load. I've had a technician from the ISP over here to test the hardware, and everything is in pristine condition. They have no other explanation than a configuration error on my machine, a possibility I can exclude 90% because I'm experiencing the same problems with another machine. I will have to monitor the situation now, and I would like to run a program that logs when internet connections become slow. I thought about putting something together using at and wget. Does anybody know of some other tool for this that does this out of the box - maybe something with an adjustable request frequency, logging connection speeds etc.?

  • Uninstalling hard deleted application from Windows7

    - by Gnanasuriyan A
    Unfortunately, I have hard deleted the microsoft sql server folder present in program files folder. So now I need to uninstall the MSSQL server from my machine. I have tried but I got an error something like "The source folder is missing". For resolving this issue, I have manually deleted the MS SQL services using "sc delete" command and I have deleted the MSSQL entry from regedit file also. But still MS SQL server entry available in "Programs and Features" list. Please guide me for solving this issue even I can't able to re install the MSSQL server once again. Thank you guys...

  • How do you make a precise countdown timer using clock_gettime? [migrated]

    - by Joshun
    Could somebody please explain how to make a countdown timer using clock_gettime, under Linux. I know you can use the clock() function to get cpu time, and multiply it by CLOCKS_PER_SEC to get actual time, but I'm told the clock() function is not well suited for this. So far I have attempted this (a billion is to pause for one second) #include <stdio.h> #include <time.h> #define BILLION 1000000000 int main() { struct timespec rawtime; clock_gettime(CLOCK_MONOTONIC_RAW, &rawtime); unsigned long int current = ( rawtime.tv_sec + rawtime.tv_nsec ); unsigned long int end = (( rawtime.tv_sec + rawtime.tv_nsec ) + BILLION ); while ( current < end ) { clock_gettime(CLOCK_MONOTONIC_RAW, &rawtime); current = ( rawtime.tv_sec + rawtime.tv_nsec ); } return 0; } I know this wouldn't be very useful on its own, but once I've found out how to time correctly I can use this in my projects. I know that sleep() can be used for this purpose, but I want to code the timer myself so that I can better integrate it in my projects - such as the possibility of it returning the time left, as opposed to pausing the whole program.

  • Computer Software Needed

    - by captfrankie
    A friend started my website with Frontpage 2000 in Oct04. I used it until 09 and started to use Kompozer. I am starting to have difficulty updating my picture pages. Some pictures never show up or show up as X. I'm not sure what the problem is. I haven't been able to figure out how to upload files to Filezilla either. Is there a software program similar to Frontpage and Kompozer that will allow me to do weekly updates/addition to my picture pages without recreating the whole page? I dabbled with Web Builder 8-Easy WebEditor-Expression Web and Pagebreeze.

  • I've failed at PHP several times. Is Ruby the Cure? [closed]

    - by saltcod
    Extremely, extremely subjective question here, but its something I've been struggling with for quite a while. I've seriously tried to become a reasonable PHP coder for the past several years. But I've really failed every time. I hate to describe myself as a beginner, b/c I've been designing websites (using WordPress, Drupal, etc) for years, but still I just can't seem get better at programming. Could it be that I have some kind of allergy to PHP? I went through Chris Pine's awesome into to Ruby about a week ago (for about the fifth time), and though it did all all seem much clearer to me than PHP, I wondered if I was just switching languages to find an easy way out? The things I struggle with in PHP all seem elementary—when to use a function, how to return database queries in foreach/while statements, when to turn those queries into reusable functions, adding arguments to functions, etc, etc. And all the OOP stuff that I keep seeing these days just files over my head. I guess my question(s) are: Am I going about learning how to program in the wrong way? Do I have some aversion to PHP that's preventing me from catch on? If I keep pushing at Ruby/Rails, will it just eventually 'click'. Or, the one I fear, am I just unlikely to ever be a programmer? Honesty appreciated. Terry

  • apple adress book mass email [on hold]

    - by Thijser
    I have been asked to help a small non profit organasation with some IT problems. They currently have a mailing list of around 200 people saved on a mac inside adres book. Now currently these people are send emails in groups of around 20 as the standard apple email program does not allow more. I know that there are programs that can be used to send email to a larger number of people however these usually require a database and I'm not sure how to use those. Anybody got any tips?

  • How do I switch between Java 7 and Java 6 on mac OS X 10.8.2?

    - by Nikita Jerschow
    I am using Java SE 7 to program simple games for windows and mac, but I have to switch to java 6 to run games such as Minecraft on my computer. This used to work just fine before I updated to Mac OS X 10.8.2 Build 12C60. Before this update I used to be able to open java preferences and check off java 6 or java 7. But now I don't seem to be able to find java preferences. I am running mac OS X 10.8.2 (latest version) Thanks.

  • What do BCU.exe and BCUService actually do?

    - by ChrisF
    I've got a Gigabyte G32M-ES2L motherboard with an Intel Core 2 Duo E7500 2.93GHz CPU running Windows XP SP3 (fully up to date). Today when I booted the machine my firewall (Sygate Personal Firewall) warned me that BCUService.exe wanted to make a call out to the internet. Wondering what they were I did a Google search and while I found out that these programs weren't malware, I didn't find out what they actually do. The information seemed to boil down to: Part of Browser Configuration Utility Auto-recovery Service from DeviceVM, Inc. This program is not important for your system process, but should not be terminated unless suspected to be causing problems. Source So before I remove them from my system does anyone know what they actually do and its it worth them taking over 4Mb of memory?

  • Azure Linux out of band managment

    - by faker
    I have a Linux (Ubuntu) virtual machine running on Azure. It seems like the only way to connect to it is via SSH. This is OK for normal operation, but what to do when something goes wrong (fsck waiting for user-input, new kernel doesn't boot, mis-configured network, etc.)? There is a grayed out "Connect" button in the management interface, and the help for it says: To access a virtual machine running Windows Server, click Connect and follow the instructions. Enter the password that was set when the virtual machine was created. The Connect button is not available for a virtual machine running Linux, but you can use your favorite SSH program to access it. I've read the documentation on the command line tools, but there is also no way to connect to it. Is there any way for me to get such a console?

  • Programming ... where to start?

    - by agnesb
    For the last 4 months, I've working tirelessly on a project with my partner, who is a super programmer. He did 100% of the whole mechanism that makes our site work. My job is to take care of the cosmetic aspects of the site ... thus I should say I am good enough at CSS and html. However, since we are using Drupal to build our site, from time to time, I need his help in order to figure out how to do the customization. Sometimes, I got frustrated. I know that as a partner, I should know a little bit on how to program. However, during the crunch time when you have to deliver lightning fast (we have our site built from scratch to finish in 4 weeks ... and you are all welcome to come join the fun! It's a site for programmers!) there is no time to learn from the basics. All I can do is to pick up whatever I need at the moment. Now the site is launched, I am thinking it should be time to do some learning. So, where should I start? My partner always said I need to start with Python. What's your take on this? Thanks.

  • SQL 2008/2005 Hosting :: Error - “Named Pipes Provider, error: 40 – Could not open a connection to SQL Server”

    - by mbridge
    When setting up a Microsoft Windows Server 2008 system, I went through the motions to set up IIS, MS SQL Server 2008, and Visual Studio 2010 to use as a test-bed. One of the immediate benefits of setting up such a system is that most development can be done remotely: MS SQL Server Management Studio, Visual Studio’s Web development suite, as well as file shares, remote desktop, etc, make for a great way to remotely develop in ‘pristine’ conditions. But there are drawbacks, too, such as needing to deal with firewall issues, not being able to penetrate past a router or the requirement of setting up a VPN. One of the problems I encountered when trying to remote into the MS SQL Server 2008 that I’d set up was the following error: Named Pipes Provider, error: 40 – Could not open a connection to SQL Server I followed the below steps, and was able to connect to the server after just a few moments of tinkering: 1. From the server in question, surf to this Microsoft article, and download and install the Firewall rules modification program. Never drop your firewall, even on a development machine, unless you have a really good reason to. 2. Launch SQL Server Configuration Manager. Navigate to SQL Server Network Configuration, then Protocols for your server name. Enable TCP/IP and Named Pipes by right-clicking and choosing Enable for each given Protocol Name. 3. Restart the SQL Server service from Services (or from command line, subsequently run “net stop mssqlserver” then “net start mssqlserver”. 4. Try your remote connection once more, and you should be able to connect. It’s not a terribly difficult concept, but one of the more challenging tasks developers face is dealing with environment setup. And while there is a certain blurred-line overlap between software development and server administration, sometimes the latter is daunting, especially given that you might set up only a handful of servers during your career.

  • How do I tell my parents that landing a job is what actually counts?

    - by shovonr
    On one side, I just want to get a degree with a 3.0 GPA. On the other side, my parents want more than just a 3. Now here's the thing. I program with a passion. I spend day and night programming. And I ace all my programming courses. However, I do terrible on all my elective courses -- such as writing, history, and all that stuff -- which only leaves me with a 3.1 to 3.2 GPA. And my parents want more. They think that university is like high school, where you need super-stellar grades to get to the next level. But they don't realize that good enough grades will land me a job. And they don't realize that a programmer needs to practice to become good at programming, and that having good skills is what will land a job in a nice software development company. Thankfully, though, they don't threaten to beat me with a baseball bat or anything like that. They just occasionally give me the little "tsk-tsk". But even that little "tsk-tsk" makes me feel guilty for opening up an IDE. And on top of that, I procrastinate because of that feeling of guilt. So now, I want to come clean with them. I want to know what's a good way to do that. [Edit] OK, so now, I realized, I should aim for higher grades, as some have suggested below.

  • Put Google Chrome, AVG on a flash drive

    - by duncan12
    I often install programs on others' computers such as LibreOffice, which, when they only have a dial-up connection, takes forever to download. So instead I keep it on a flash drive and install it from there. This works fine for LibreOffice. However, some programs, when you download them all you are downloading is a downloader - when you download ChromeSetup and open it, a installer window opens which actually downloads Chrome. Dial-up users then see that it will take 4 hours. Another example is AVG free antivirus - you download an installer, which when opened actually downloads AVG. However this doesn't work too well for dial-up users. How do I put the entire program of things like Chrome and AVG on a flash drive for fast installation on others' slow connections?

I've looked online and the best page I've found to try and help is this one: http://forums.majorgeeks.com/showthread.php?t=182720 Which says to uninstall Java using Revo or Windows Cleanup. However nether program says I have Java installed. From what I've read this is a uninstall problem when Java is not really uninstalled. How do I make sure Java is completely uninstalled? Do you have any other suggestions for me to try?

  • Running suspicious X programs in GNU/Linux

    - by Vi
    What the most harmful thing can malware program started as separate limited user account do if it has access to the X server? Network and filesystem things are already considered by chroot and netfilter. It obviously can lock the screen and I will need to switch to other vt and kill it manually. Can it for example disrupt other GUI programs on the same X server (access to root terminal in nearby window)? I know that it is safer to run it in separate X server, for example, in Xtightvnc or even some virtual machine, but how dangerous is to just run it like other programs?

  • Hide or Show singleton?

    - by Sinker
    Singleton is a common pattern implemented in both native libraries of .NET and Java. You will see it as such: C#: MyClass.Instance Java: MyClass.getInstance() The question is: when writing APIs, is it better to expose the singleton through a property or getter, or should I hide it as much as possible? Here are the alternatives for illustrative purposes: Exposed(C#): private static MyClass instance; public static MyClass Instance { get { if (instance == null) instance = new MyClass(); return instance; } } public void PerformOperation() { ... } Hidden (C#): private static MyClass instance; public static void PerformOperation() { if (instance == null) { instance = new MyClass(); } ... } EDIT: There seems to be a number of detractors of the Singleton design. Great! Please tell me why and what is the better alternative. Here is my scenario: My whole application utilises one logger (log4net/log4j). Whenever, the program has something to log, it utilises the Logger class (e.g. Logger.Instance.Warn(...) or Logger.Instance.Error(...) etc. Should I use Logger.Warn(...) or Logger.Warn(...) instead? If you have an alternative to singletons that addresses my concern, then please write an answer for it. Thank you :)

  • How would I Enable FTP on Home PC (Win7)?

    - by jp2code
    In my home, all PCs connect through a small router. Some wired and some wireless. Our Media PC (HTPC) is controlled via a Media Center TV style remote, so managing files on it is tedious. I can access all of the files on the HTPC from my desktop PC, but moving a 6 GB file from \\HTPC\Folder1 to \\HTPC\Folder2 involves copying the data to the desktop and then transferring it back. If I were on the HTPC, this would likely be handled by a simple address change for the file (i.e. it would be done almost instantly). I'm thinking if I could get an FTP program to connect to the HTPC, I could simplify things ...but how do I enable that ability on the HPTC? Then, how would I go about connecting to the HTPC? Would I simply enter \\HTPC as the FTP address?

  • Low end dedicated GPU vs. integrated Intel graphics (for light CAD work)

    - by PaulJ
    I have been asked to spec a PC for an interior design business. They are going to do some AutoCAD work (but they won't be using massive datasets or anything), and also use Kitchen Draw, a program that has 3D visualization features and says, in its requirements, that "a recent NVidia or ATI card might be enough". Since they are very limited budget-wise, I had originally picked a GeForce GT 610 card, but this card is so low end that I'm left wondering whether it will be an improvement at all over the dedicated Intel HD2500 graphics chip that comes with the CPU (I will be using an Ivy-Bridge Intel i5). Most of the information I see around is for gaming, which isn't really relevant in my case. Basically, for the use case I've described (light 3D work), can one get away with a current Intel HD graphics chipset? And will a low end GPU like the GT 610 provide a noticeable improvement?

  • how to recover data from my disk - I accidentally copied with dd an iso on it

    I wanted to create a bootable usb from an iso image and i accidentally put as the output of the dd, instead of my usb drive, one of my hard disks. The iso was 3,3 GB and my disk is 1TB! And it was almost full. Can i at least restore the data that has not been overwritten? Right now i can't even mount it. I get this error: Error mounting /dev/sdd1 at /media/main/UDF Volume: Command-line `mount -t "udf" -o "uhelper=udisks2,nodev,nosuid,uid=1000,gid=1000,iocharset=utf8,umask=0077" "/dev/sdd1" "/media/main/UDF Volume"' exited with non-zero exit status 32: mount: wrong fs type, bad option, bad superblock on /dev/sdd1, missing codepage or helper program, or other error In some cases useful info is found in syslog - try dmesg | tail or so Also since i know which filesystem my disk used if i reformat it to this filesystem is there any chance i can mount it and retrieve the rest of the files?
