  • Why are Asynchronous processes not called Synchronous?

    - by Balk
    So I'm a little confused by this terminology. Everyone refers to "Asynchronous" computing as running different processes on seperate threads, which gives the illusion that these processes are running at the same time. This is not the definition of the word asynchronous. a·syn·chro·nous –adjective 1. not occurring at the same time. 2. (of a computer or other electrical machine) having each operation started only after the preceding operation is completed. What am I not understanding here?

  • Google App Engine dev_appserver can't find PIL (I've installed it)

    - by goggin13
    I recently upgraded my Google App Engine launcher on my Mac, running OSX 10.5.8, and afterwards my projects that work with images stopped working locally. It seems to be the same problem that I had when first using GAE locally to work with images, before I installed PIL. Here is the error I get: SystemError: Parent module 'PIL' not loaded I have PIL installed. When I run python normally, I can access it and work with it as expected. I also checked to ensure that dev_appserver.py was running the same version of Python. If I open the interpreter and type sys.version I get this back: 2.5 (r25:51918, Sep 19 2006, 08:49:13) [GCC 4.0.1 (Apple Computer, Inc. build 5341)] This is identical to what I get when I display the sys.version from my projects running through dev_appserver. Any thoughts on why dev_appserver can't find the PIL module? I have been banging my head against this for a bit. Thank you!

  • Including external C++ libraries in version control

    - by m0tive
    I'm currently starting a project which is going to be developed on a few different computer and I'm keeping in sync with bzr. In the project I'm using a couple of 3rd party libraries, like SDL. In the past I've just pushed a copy of the compiled library to my version control, but that usually seems to massively inflate the size of the branch and generally seem like a bad idea. Is that the normal practice, just pushing the required libraries, or is there a better way of added libraries to distributed version control like bzr or git? (I know on svn you can use svn:external to do something similar to this)

  • Accessing a webpage in C++

    - by wyatt
    Is there a good, simple library which allows C++ to load a webpage? I just want to grab the source as text. I'm not using any IDE or significant library, just straight command line. Tangentially, is there something fundamental I'm missing about programming in C++? I would think any language in common use today would have droves of web-based functionality, being so central to computer usage, but I can find next to no discussion on how to accomplish it. I realise C++ significantly predates the modern internet, so it lacking any core ability in the regard is reasonable, but the fact that relevant libraries seem so sparse is baffling. Thanks for your help.

  • How to quantify your "slow" development machine?

    - by lance
    ( Please provide the question this one duplicates. I'm disappointed I couldn't find it. ) My development machine is "slow". I wait on it "a lot". I've been asked by decision makers who want to help to fairly and accurately measure that time. How do you quantify the amount of time you spend waiting on the computer (during compiles, waiting for apps to open every day, etc). Is there software which effectively reports on this sort of thing? Is there an OS metric (I/O something something, pagefile swapping frequency, etc, etc) that captures and communicates this particularly well? Some sort of benchmark you'd recommend me testing against?

  • What FPGAs (Field-Programmable Gate Arrays) can one buy to experiment with at home?

    - by Joe Blow
    What the heck is an FPGA -- where can I buy one? What sort of system do you need to experiment with them? How to program them? Can you "load" if that's the right terms an FPGA using an ordinary mac or perhaps other *nix or windoze computer? Where can I buy some FPGAs today to experiment with ??! Are they expensive this only available to industry or can I buy one today? Does anyone know about this? Thanks! I have become interested in FPGAs after reading this question... Holistic Word Recognition algorithm in detail

  • Tools for displaying text, powerpoint style, in linux

    - by Will Mc
    I have a problem where I need a way to display a repeating series of "images" on a computer monitor. Specifically, given a series of text files, I'd like a way to display the contents of said files on a screen in a way much like a powerpoint would. My current thoughts are to find some tool that will take in a text file of some format, and then output an image which contains the text from the file. Then I'd put it in a directory and have some Slideshow program continuously go between the images in that directory. It's a very hacky solution, obviously. So, does anyone know of tools that would do such a thing? Or is there a better way to do this? I've looked into the library libgd2, but it doesn't seem to support text-wrapping for images, which is something I'd need. Thanks!

  • SVG Animation in Python? - Any options other than Things! 0.4?

    - by ThantiK
    I recently gave my daughter some time on the computer, and she really likes a program called 'BabySmash!', and I also have another program that came with a keyboard attachment called 'Laugh, Smile & Learn' from playschool I think. I'm not a python guru by any stretch of the imagination and I kind of have it in my head that I want to create some sort of program in the spirit of these two, with vector animation and sounds. Thing is, it doesn't look like there are many options for vector animation in python. I found a library called Things! 0.4, but it's lacking in-depth documentation and seems to be more of an experiment in vector animation rather than a full blown solution. Are there any options that I'm not immediately finding? What other animation-libraries do you recommend? Even if the library isn't vector-based, ease of use is probably the strongest factor in my use.

  • Passing CMD Results to Variable in a Batch File

    - by TripleNad
    I am trying to install an application and a group of services using PSTools, but I want to take into account that the computer I am trying to connect to may be turned off or on a different network, which is not reachable from the internal network. Basically if the machine is not able to be accessed through the admin share, this is the message that I am getting: Couldn't access MachineName: The network path was not found. Make sure that the default admin$ share is enabled on MachineName. This is the syntax I am using to try to capture the "Error Message" and then report back that if installation was successful or not (depending on if it can contact the machine) @echo off set /p name=What is the machine name?: psexec.exe \\\%name% -u *useraccount* -p *password* \\\ServerName\installation.bat FOR /F "tokens=*" %%A IN ('COMMAND ^| FIND "Couldn't access"') DO SET Error=%%A If "%Error%"=="Couldn't access" ECHO Installation Failed. Else ECHO Installtion complete. Pause exit Currently it hangs right at the point it's defining the Error Variable. Can't quite figure out what I am going wrong here.

  • Validate decimal number in (known) national format

    - by Álvaro G. Vicario
    PHP has many built-in functions to validate numbers but they all expect input in computer format: 1234.56. I need to validate stuff like 1,234.56 (English) or 1.234,56 (Spanish), together with some typical attributes (accepted range, max number of decimals, etc.). I started writing my own function but I soon got lost. It's easy to read the user input into a float variable but I want to be able to detect numbers with invalid formats like 1,23456.7 or 1..25. Do you have any recommendation on the subject? (Decimal and thousand characters are known beforehand and it's okay to hard-code digit groups as three, there's no need to cover Indian number format.)

  • IIS Not working

    - by 3bd
    I have a web site that built on Visual studio 2008 and i need to run it from my computer (Win 7 Ultimate) as a server I tried to publish it to IIS and this is simply not working and i have the flowing error : Error Summary HTTP Error 500.19 - Internal Server Error The requested page cannot be accessed because the related configuration data for the page is invalid. Config Error This configuration section cannot be used at this path. This happens when the section is locked at a parent level. Locking is either by default (overrideModeDefault="Deny"), or set explicitly by a location tag with overrideMode="Deny" or the legacy allowOverride="false". any one can help?

  • Multiple things at once (Threads?)

    - by Jonathan
    All, What is a really simple way of having a program do more than one thing at once, even if the computer does not necessarily have multiple 'cores'. Can I do this by creating more than one Thread? My goal is to be able to have two computers networked (through Sockets) to respond to each-other's requests, while my program will at the same time be able to be managing a UI. I want the server to potentially handle more than one client at the same time as well. My understanding is that the communication is done with BufferedReader.readLine() and PrintWriter.println(). My problem is that I want the server to be waiting on multiple readLine() requests, and also be doing other things. How do I handle this? Many thanks, Jonathan

  • What to add to git repo?

    - by Ryan
    I am doing a video player. I have the following in my project folder: these four dirs should each be on their own line: /source /sample_applications /images /videos Right now the repo just includes the /source directory...which is code only. It is on my local computer. I am thinking of adding it to git hub. My question is: should I add the sample apps, the images and the videos to the repo? Is that something that people normally do and that other people want people to do? Can git even handle videos(noob here)?

  • Get path to a file via flash

    - by jeffkolez
    I'm not a flash dev, but I'm turning to it to try and meet a requirement. I'm to allow a user to select a file on their computer, then pass it to my web application. I know it's not possible to do this using Javascript, hence wanting to use flash. First, is this possible? Second, can I get a pointer on how its done? To clarify: I'm just looking for the path to the file. I don't want to upload it.

  • Configuring 2 XBee Modules on OSX for wireless connection

    - by Annette
    I am trying find out how and with which program for OSX (10.5.8) I can configure serial ports? I am trying to establish a wireless connection between two Xbee´s (RF modules) and cannot figure out how to use ZTerm nor screen under Terminal. The setup I am using is: an Arduino+Xbeeshield+Xbee with external power supply, and an xbee on the xbee explorer connected to the Computer via USB. I am trying to gather information on this through various forums, but most of them cover the configuration issue for PC using X-CTU (which I tried with CrossOver but it doesn´t recognize ny of my ports). According to one source, using screen under Terminal should show me all my serial ports, particularly /dev/tty.KeySerial1 - but it doesn´t show, even though I´ve plugged in both my arduino+xbee shield and the xbee on the explorer.

  • How determine application subsystem from executable file

    - by Luca
    I'm trying to detect console application from the list of the executables files installed on my computer. How to implement it? Every application has a "subsystem" (windows application, console application or library; specified to the linker as option, I think). How to detect it using only the executable file? Are there alternative methods to detect the application characteristic? Additionally, are there any method for detecting the file is a really executable file? Any issue for JAR executables?

  • Why are items being placed below?

    - by Adam DePolo
    This is really confusing and I have never had this occur. For my computer, it is fine. But for anyone else's computer I have tried, it screws up. So on my site, designatease.com , the second bar down, it places the fifth item down below the first four. I am not sure why it is doing this. I want them to span across the bar but the stop at about half way. Help me out SOF.

  • Where does memory dynamically allocated reside?

    - by Summer_More_More_Tea
    Hello everyone: We know that malloc() and new operation allocate memory from heap dynamically, but where does heap reside? Does each process have its own private heap in the namespace for dynamic allocation or the OS have a global one shared by all the processes. What's more, I read from a textbook that once memory leak occurs, the missing memory cannot be reused until next time we restart our computer. Is this thesis right? If the answer is yes, how can we explain it? Thanks for your reply. Regards.

  • Automatically selecting and creating class objects

    - by Omin
    Lets say that we have a box class: class Box { private int width; private int height; //Box Constructor public Box( int height ) { this.height = height; width = 450; } } and a series of Box objects in our main: Box Box1 = new Box(147); Box Box2 = new Box(178); Box Box3 = new Box(784); Is there a way to use a "for" loop to go through these objects? Also, how would you make the computer create class objects for us? eg. create 10 objects using: for( int i=0; i>10; i++) { //method }

  • Efficient bitshifting an array of int?

    - by nn
    Hi, To be on the same page, let's assume sizeof(int)=4 and sizeof(long)=8. Given an array of integers, what would be an efficient method to bitshift the array to either the left or right? I am contemplating an auxiliary variable such as a long, that will compute the bitshift for the first pair of elements (index 0 and 1) and set the first element (0). Continuing in this fashion the bitshift for elements (index 1 and 2) will be computer, and then index 1 will be set. I think this is actually a fairly efficient method, but there are drawbacks. I cannot bitshift greater than 32 bits. I think using multiple auxiliary variables would work, but I'm envisioning recursion somewhere along the line.

  • How to analyse Wikipedia article's data base with R?

    - by Tal Galili
    Hi all, This is a "big" question, that I don't know how to start, so I hope some of you can give me a direction. And if this is not a "good" question, I will close the thread with an apology. I wish to go through the database of Wikipedia (let's say the English one), and do statistics. For example, I am interested in how many active editors (which should be defined) Wikipedia had at each point of time (let's say in the last 2 years). I don't know how to build such a database, how to access it, how to know which types of data it has and so on. So my questions are: What tools do I need for this (besides basic R) ? MySQL on my computer? RODBC database connection? How do you start planning for such a project?

  • Does anybody have practice in programming PCMEF - architectures?

    - by Erkki
    PCMEF is an architecture style presented in the book Practical Software Engineering by Maciaszek and Liong. The layers are: P: Presentation C: Controller M: Mediator E: Entity F: Foundation. It is some kind of enchancement compared with MVC - architecture. I recommend it to interactice, data and communicating - oriented purposes. I have programmed it using Visual Prolog. Foundation in my applications is the data model (domains) for the application. PCMEF is like a simulated computer: Presentation is the display, Controller the user interface and event handling, Mediator the internal logic and data highway. Entity is the database or external interfaces and F defines the knowledge. This is a really nice small architecture. Does any other have experiance of it?

  • How Proxy server works with tcp/http connections?

    - by Vivek
    Since I am a beginner in the world of internet/networking, I always mess up with these kinds of doubts in my head while programming ;) .. My doubts are, While working behind a proxy, how my requests and responses work? Means my request headers and data will first reach to Proxy server- then proxy server sends it(same headers and data) to corresponding server. And server responses to it with a response header and body to the proxy server-then proxy server sends it to my computer. Wright? While using websockets we are upgrading our http connection to tcp. At this time what is happening @ Proxy server? Does the proxyserver also upgrades its connection to plain TCP? After opening such TCP connections, does the proxy server able to track/log those socket messsages? And most importantly, Is the proxy server transparent or acting like an original server infront of a client? Thanks for any answers or helpful links in advance.

  • The conventional location for storing my Java libraries and applications in UNIX based systems

    - by Bytecode Ninja
    I usually store the Java applications and JAR files that I download from the Web in the ~/Java folder on my computer (an OS X machine). I have been doing this since the days when I was a Windows user. However I think in UNIX based systems user local apps are conventionally stored in another directory. I have a feeling that this directory should either be /usr/local/, /usr/local/USERNAME, /opt/local, or /opt/local/USERNAME but I am not sure. Any ideas which directory can I use for this purpose? Please note that, I am talking about archive files that I download from the Web, unpack and use locally and not programs that have installation scripts or MacPorts, etc.

  • Is it faster to count down than it is to count up?

    - by Bob
    Our computer science teacher once said that for some reason it is more efficient to count down that count up. For example if you need to use a FOR loop and the loop index is not used somewhere (like printing a line of N * to the screen) I mean that code like this : for (i=N; i>=0; i--) putchar('*'); is better than: for (i=0; i<N; i++) putchar('*'); Is it really true? and if so does anyone know why?
