  • Code reading: where can i read great, modern, and well-documented C++ code?

    - by baol
    Reading code is one of the best ways to learn new idioms, tricks, and techniques. Sadly it's very common to find badly written C++ code. Some use C++ as it was C, others as if it was Java, some just shoot in their feet. I believe gtkmm is a good example of C++ design, but a binding could not be the better code to read (you need to know the C library behind that). Boost libraries (at least the one I read) tend to be less readable than I'd like. Can you mention open source projects (or other projects which source is freely readable) that are good example of readable, modern, well-documented, and auto-contained, C++ code to learn from? (I believe that one project per answer will be better, and I'd include the motivation that led you to selecting that one.)

  • Using a script that uses Duplicity + S3 excluding large files

  • Cannot open SQL 2005 database in SQL server Management Studio 2008 R2 on Windows 7

    - by Darryl Lawrence
    I have Windows 7 64bit as my OS + SQL Server 2008 R2 installed. I can connect to SQL Databases (2008), but cannot connect to a SQL 2005 database. I can, however, connect to the 2005 SQL Database on a PC that has Windows XP as the OS and also has SQL Server 2008 R2 installed. So it seems that it works fine on XP but not on Windows 7 (32 or 64bit). is this an Operating System issue? Error message: Cannot connect to OMRSQLV016\PRODSQL002. =================================== A network-related or instance-specific error occurred while establishing a connection to SQL Server.

  • What is it that automatically checks config changes (such as those in /etc) into git?

    - by Brandon
    I remember reading on the ubuntu forums some time ago about a program to automatically check configuration changes into version control for you. It was (of course) not Ubuntu-specific. I'm pretty sure it used git, though it may have been svn, or perhaps even able to work with multiple different VCSs. My Googling has turned up nothing, and I'd rather not roll my own script if someone has already done this well. Of course I could just manually check things in, but there are reasons I'd like it done automatically. (I'm actually planning to use this for my LastSession.plist file for Safari, so when the #@$%^*&! thing crashes, and I don't restore everything, and then Leopard crashes, the fact that it has such lousy session management won't mean I lose the dozens of windows with dozens of tabs I had open.)

  • Executed PHP files are stale unitl "touched" (Symlinked NFS mount as web root)

    - by mmattax
    We have a PHP application that has 3 web servers (running Nginx and Apache). The web server's directory root are symlinked directories that point to an NFS mount. For example: web01 has an NFS mount at /data/webapp, which is symlinked to /home/webapp. Apache serves content from /home/webapp/www. We also use ACP for our PHP opcode cache. When we deploy code, we SCP an archive file to the NFS server and extract it. Since upgrading RedHat 6, when we deploy our code the webserver execute "stale" PHP files until touch is run on the PHP files. We thought that APC might be causing a problem, but the issue exists, even after clearing the opcode cache. Any ideas on how to diagnose why the stale PHP code is being executed?

    - by Kabeer
    Hello. I am a consultant and will be working with geographically distant clients. I am looking for a solution to collaborate with my clients effectively in all the phases of the projects (architecture, requirements, design, construction, testing, deployment, maintenance). My hunt is for something in the open source (and preferably free) space and also on .Net platform. I need to record my communication with the clients and with growing no. of clients I should not miss out capturing any information. Please recommend.

  • Delete specific files after installation using visual studio setup project

    - by Vadiklk
    I have this problem. I want to build an installer for my c# solution, that will be placed in a folder with other installation folders and files that are needed to be copied to the installed folder. So that is easy, I just copy them to the folder I create using the folder structure I want. Now, I want also to install another program and run a .exe file I've created to unzip some files for me. For that I need to copy 2 .exe files and 2 dlls (for the exes) to the folder to which I am installing and create 2 custom actions that will use them. That I've managed to do. After that I want to delete those 4 extra files, as the user does not need them and shouldn't even be aware they are there. How to do so? I couldn't find a way in the built in setup project preferences + I do not know how to make a custom installer class. A bonus question, is how to make the other installer (one of the .exe files is just a plain installer) install quietly to any path? I do not want the user to see an installer pop out of my program installer. Thanks!

  • Grand Central Strategy for Opening Multiple Files

    - by user276632
    I have a working implementation using Grand Central dispatch queues that (1) opens a file and computes an OpenSSL DSA hash on "queue1", (2) writing out the hash to a new "side car" file for later verification on "queue2". I would like to open multiple files at the same time, but based on some logic that doesn't "choke" the OS by having 100s of files open and exceeding the hard drive's sustainable output. Photo browsing applications such as iPhoto or Aperture seem to open multiple files and display them, so I'm assuming this can be done. I'm assuming the biggest limitation will be disk I/O, as the application can (in theory) read and write multiple files simultaneously. Any suggestions? TIA

  • How to open a page in Chrome from the command line, in a new tab or an existing tab as appropriate?

    - by MattH
    I'm looking for a way to open a given page in Google Chrome from the command line, with the following behaviour: If the given page is already open in a tab, navigate to that tab If the given page is not already open in a tab, open the page in a new tab and show that tab Currently when I open a URL from the command line (e.g. using "open http://godzillahaiku.tumblr.com" on Mac OS X), Chrome will always open the URL in a new tab. I end up with lots of duplicate tabs as a result, which is a minor annoyance. I'm looking for a solution that works on Mac OS X, but a non-OS specific solution would be preferable. I'd consider writing a Chrome extension for this if there's no existing solution.

  • Checking whether binary files are the same ?

    - by ldigas
    What would be the easiest way of veryfying whether two binary files are the same, without actually opening them, checking versions and such in different programs ... ? I primary mean files like 3d models, acad drawings, and the like, of which I have different versions, saved in different directories, and upon completing, I just want to find which are the newest, and which are different from the newest, and delete every other. So far I've thought od md5 ? Any other ideas ? This doesn't actually fit under "diff" tag so feel free to change it, if you can think of a better alternative.

  • Are there any open source reseller packages?

    - by Tom Wright
    My department has just been given the right/responsibility to manage our own VPS. The idea being that the bureaucracy will be less for the many small web projects we run. Since each project will be managed by a different team, I was planning on approaching a shared hosting model. Are there any free pieces of software that would help automate the provision of resources each time a team request a new project? Most of the projects have identical requirements - basically LAMP - so it would be these resources that I would want provisioning (and de-provisioning, if that is a word) automatically. Ideally, there would also be a way to hook it into our LDAP authentication backend too, though I could probably make this sort of modification if necessary. Since we won't be charging our "client" however, we won't need the ability to generate invoices, handle payments, etc. etc. EDIT: Sample workflow Login authenticated against LDAP Username checked against admin group (not on central LDAP) Click 'new project' and enter project name User created on VPS with project name as username Apache virtual host created and subdomain (using project name) allocated FTP & MySQL users created

  • Apache Prepending Header Information to ALL FILES

    We're in the middle of setting up new servers, and have been having some odd problems with Apache. Apache is prepending text that looks like this: $15plðI‚‚?E?ðA™@?@??yeÔ|~Ÿ²?PγZ" zS€?8i³?? ,ÀŠ{ÿBHTTP/1.1 200 OK Date: Mon, 02 Feb 2009 22:28:05 GMT Server: Apache/2.2.3 (CentOS) Last-Modified: Mon, 02 Feb 2009 22:28:05 GMT ETag: W/"1238007d-2224e-fe617f40" Accept-Ranges: bytes Content-Length: 139854 Connection: close Content-Type: application/x-javascript To all files.

  • Can I grant permissions on files in windows 7 using a security identifier from another machine

    - by Thomas
    I have an external hard drive, and I wish to grant permissions on some files to users from 2 different computers without having to hook it up to the 2 different computers. I know the SID of the user on the other computer, I'd like to know if and how I can grant permissions to files using the SID. I'm running Windows 7 Professional 64 bits, and "The Other" computer Win 7 Home Premium 64 bits, they are not in a domain, but separate computers on a home network (not even same homegroup). Note: Duplicated question with: Is there a way to give NTFS file permissions to users from other Windows installations?

  • Recover open but deleted file on Linux using ln instead of cp

    - by Yang
    Say I have a file that's downloading (from a source that's hard to re-download from), but accidentally deleted from the filesystem namespace (/tmp/blah), and I'd like to recover this file. Normally I could just cp /proc/$PID/fd/$FD /tmp/blah, but in this case that would only get me a partial snapshot, since the file is still downloading. Furthermore, once the download completes, the downloading process (e.g. Chrome) will close the FD. Any way to recover by inode/create a hard link? Any other solutions? If it makes any difference, I'm mainly concerned with ext4. Thanks in advance.

  • How to choose my own filename format for subscribed podcast files?

    - by meomaxy
    I subscribe to several podcasts where the filenames of the downloaded mp3 files have no particular pattern to them. When I copy the directory of accumulated mp3 files into my mp3 player, the files play in alphabetical order. What I really want is to play the files chronologically by release date. I currently use iTunes on Windows XP to download the files. What I do now is manually rename the files, adding the date in YYYYMMDD format to the start of each filename so that an alphabetical listing of files will correspond to their chronological order when I listen to them later in PocketTunes on my Palm Centro. Is there some way to get the release date into the filename automatically? If so, I could automate or possibly skip the file renaming step. I would switch from iTunes to something else if that would solve my problem. The file creation time on my local disk isn't a reliable indicator because sometimes I download a few days worth of content at one time, and the files don't necessarily get downloaded in chronological order.

  • Bug: files uploaded via desktop or web client have hidden tag when listed via API

    - by Jon Webb
    Files uploaded to Google Drive sometimes incorrectly have a hidden tag when listed via the Document List v3 REST API: <category scheme='http://schemas.google.com/g/2005/labels' term='http://schemas.google.com/g/2005/labels#hidden' label='hidden'/> This happens if: a subfolder is created via the Google Drive desktop client and files are copied in, or a folder is uploaded via the Google Drive web client. The folder does not have the hidden tag, but the files that were uploaded do. The files do not have this tag if: they are individually uploaded via the Google Drive web client to the subfolder, or they are uploaded via the REST API to the subfolder, or they are uploaded via the desktop client to the My Drive root. The files and folders show up in Google Drive whether they have the hidden tag or not. We're using the API with the following scope: https://docs.google.com/feeds/ https://spreadsheets.google.com/feeds/ https://docs.googleusercontent.com/ I have verified and can recreate this with the OAuth 2.0 playground. Google Drive desktop client version 1.3.3209.2600 on Win7 32-bit I guess these must be bugs in the API...

  • In Lisp, Avoid "Cannot open load file" when using require

    - by Jesse
    I am working on a custom .emacs file that I will be able to use on several different computers. I would like to be able to load a mode if it exists on the system. If it does not exist I would like Emacs to stop showing the error: File error: Cannot open load file, X. For example: (require 'darkroom-mode) Results in: File error: Cannot open load file, darkroom-mode I am using file-exists-p to test if certain other files exist but for this test I would assume I need to search my load-path. I am new to Lisp so this is stumping me.
