  • Enforce VPN connection to access the Internet

    - by ch0wn
    I'm using a VPN when I'm online at an unencrypted wifi. Unfortunately, at my university the connection is quite unstable and at every reconnect the VPN connection is terminated and I manually need to reconnect to it using the NetworkManager, which obviously only works if I notice the reconnect. I enabled the option to automatically connect to the VPN in the NM options, but it seems to have no effect. Is there a way to enforce an active VPN connection before any other application can access the network connection so I can be sure not to send private data over unencrypted connections? Cheers, Pascal

  • Torque2D, Class vs Datablock

    - by Max Kielland
    I'm scripting my first game with Torque2D and have not fully understood the difference between "Class" and Datablock. To me it seems like Datablock is similar to a struct in C/C++ or a Record in Pascal. If I create Datablocks with new, are they instantiated in the same way as a "Class"? I have a large TileMap and need to attach some information to each Tile. I was thinking to use a Datablock, as a struct, to attach this information to the tile's CustomData property. The two questions are: What is a Datablock and should I use a Datablock or a "Class" for this tile information?

  • Any enlightenment for understanding Object Oriented Programming? [closed]

    - by ????
    I studied computer science near the end of 1980s, and wasn't taught OOP that formally. With Pascal or C, when I understand the top-down design of functions, and the idea of black box, then everything just seem to make sense, as if there is a "oh I get it!" -- some kind of totally getting it and enlightenment feeling. But with OOP, all I know was the mechanics: the class, instance, method, inheritance, polymorphism, encapsulation. It was like, I knew all the "this is how it is", but never had the feeling of "I totally get it", the enlightened feeling. Would somebody be able to describe it, or point to a chapter in some book or paper which talks about OOP so that the reader can feel: "I totally get it!" on OOP?

  • What happened this type of naming convention?

    - by Smith
    I have read so many docs about naming conventions, most recommending both Pascal and Camel naming conventions. Well, I agree to this, its ok. This might not be pleasing to some, but I am just trying to get you opinion why you name you objects and classes in a certain way. What happened to this type of naming conventions, or why are they bad? I want to name a struct, and i prefix it with struct. My reason, so that in IntelliSense, I see all the struct in one place, and anywhere I see the struct prefix, I know it's a struct: structPerson structPosition anothe example is the enum, although I may not prefix it with "enum", but maybe with "enm": enmFruits enmSex again my reason is so that in IntelliSense, I see all my enums in one place. Because, .NET has so many built in data structures, I think this helps me do less searching. Please I used .NET in this example, but I welcome language agnostic answers.

  • Lua and multi-paradigm programming: scope and capabilities

    - by Ef Es
    Despite having started learning programming with Pascal and C, after the jump to OO (C++, Java) I lost sense of the structured programming paradigm. I have started learning Lua and I have researched many tutorials, but all of them only cover basic operations and language features and capabilities. They feel more like a reference doc than a programmer's guide. Now, when trying to work with day to day tasks, how does one go through most common design patterns like observer, or multithreaded programming, creating UI elements and polling system calls for keyboard or sensors? Is it even feasible in this languages or you have to work with the C binding, libraries and low-level programming to get most stuff done? Do I get the Lua scope wrong?

  • how to have 'find' not return the current directory

    - by Pinpin
    I'm currently trying to find (and copy) all files and folder structure matching a specific pattern, in a specified directory and I'm so nearly there! Specifically, I want to recursively copy all folders not begining with a '_' character from a specified path. find /source/path/with/directories -maxdepth 1 -type d ! -name _\* -exec cp -R {} /destination/path \; In the /source/path/with/directories/ path are machine-specific directories beginning with '_' and others, and I'm only interested in copying the others. For a reason beyond me, the find command returns the /source/path/with/directories/ directory, and therefore copies its content, directories begining with '_' included. Anyone have a hint as to why that is? Thanks, Pascal

  • how to modify another user's .profile from the recovery console?

    - by Pinpin
    Pretty much everything is in the title, really! ;) I installed a few components to compile go programs, and the last step was to add the go directory to the path. Being a total ubuntu noob, I added the line PATH="Path/To/Folder", after the one that was already there. After the first reboot I can no longer log into ubuntu (the screen black-out for a while and then I'm back to the login screen, and the same chime greets me.) I've been able to boot in recovery mode, open the root's profile with vi, but I cant find my other user's profile, nor pretty much anything.. Any hint would be greatly appreciated! Pascal

  • Programming languages with extensible syntax

    - by Giorgio
    I have only a limited knowledge of Lisp (trying to learn a bit in my free time) but as far as I understand Lisp macros allow to introduce new language constructs and syntax by describing them in Lisp itself. This means that a new construct can be added as a library, without changing the Lisp compiler / interpreter. This approach is very different from that of other programming languages. E.g., if I wanted to extend Pascal with a new kind of loop or some particular idiom I would have to extend the syntax and semantics of the language and then implement that new feature in the compiler. Are there other programming languages outside the Lisp family (i.e. apart from Common Lisp, Scheme, Clojure (?), Racket (?), etc) that offer a similar possibility to extend the language within the language itself?

  • Change the foreground color of statusbars in irssi?

    - by Marlun
    Hello, I've changed the terminal colors and now irssi statusbars have white text on light blue background. I would like to change the foreground color of the irssi statusbars to black but can't figure out how to do it. I don't want to download a whole theme, I only want to change this one color. Any idea? Thanks in advance! -Martin

  • Automatically mounting windows share in Fedora 12

    - by user15865
    Hi, I'm trying to automatically mount a windows share in a Fedora 12 instance (FC12). When I manually mount things work: mount -t cifs //nas01/servers -o username=guest,password=myPassword /mnt/nas01/servers If I update /etc/fstab with the following: //nas01/servers /mnt/nas01/servers cifs username=guest,password=myPassword 0 0 Nothing happens after reboot. The thing that has me baffled is after a reboot if I run: mount -a The share is mounted. Any ideas on this? Thank you, Martin

  • Need for page file with 12 GB RAM

    - by MartinStettner
    Hi, I recently got my new PC with 12 GB RAM (running Windows 7 64bit). The default installation suggests a 12 GB page file on the system drive (which I think is both inefficient and expensive on a SSD drive...) I'm wondering if I need any virtual memory at all, 12 GB being more than I had on my previous machine including the page file (I had 3GB RAM + 3GB pagefile). Thanks Martin EDIT As mokubai pointed out, the question is pretty much answered in Windows 7 pagefile size with large RAM and SSD

  • Thinkpad speaker turns mute - Linux Codec issue?

    - by Curlew
    At some point a few days ago the speakers on my Lenovo Thinkpad T410 (Model number: 2537A11) suddenly stopped working randomly. This error happens every time I watch a video or listen to a music file. The sound just abruptly stops. At the moment, I can't produce a single sound no matter what I do. I am using Debian GNU/Linux on this laptop and there doesn't appear to be anything else wrong (the fan is working, no abnormal heat (staying around ~40°C), no other obvious errors or problems). Here is the output of a nice program someone pointed me to: martin@martin:~/Downloads$ sudo python run.py --monitor Using temporary directory: /dev/shm/hda-analyzer You may remove this directory when finished or if you like to download the most recent copy of hda-analyzer tool. Downloading file hda_analyzer.py Downloading file hda_guilib.py Downloading file hda_codec.py Downloading file hda_proc.py Downloading file hda_graph.py Downloading file hda_mixer.py Downloaded all files, executing hda_analyzer.py Watching 1 cards ====================================== Sound is working normally and then it stops and the following lines appear: Diff for codec 0/0 (0x14f15069): --- +++ @@ -164,17 +164,17 @@ Power: setting=D0, actual=D0 Node 0x1f [Pin Complex] wcaps 0x400501: Stereo Pincap 0x00000010: OUT Pin Default 0x901701f0: [Fixed] Speaker at Int N/A Conn = Analog, Color = Unknown DefAssociation = 0xf, Sequence = 0x0 Misc = NO_PRESENCE Pin-ctls: 0x40: OUT - Power: setting=D0, actual=D0 + Power: setting=D3, actual=D3 Connection: 2 0x10* 0x11 Node 0x20 [Pin Complex] wcaps 0x400781: Stereo Digital Pincap 0x00000010: OUT Pin Default 0x40f001f0: [N/A] Other at Ext N/A Conn = Unknown, Color = Unknown DefAssociation = 0xf, Sequence = 0x0 Misc = NO_PRESENCE And now there is also an error in the dmesg output hda-intel: IRQ timing workaround is activated for card #0. Suggest a bigger bdl_pos_adj. I changed the bdl_pos_adj to various numbers (-1, 0, 64, 1024) and either there is no change at all or dmesg reports that the adjustment is too big. I wonder if this bdl_pos_adj is the real reason for the error. Here is my hardware information provided by alsa-info.sh website. Okay, i did some serious testing and even installed Windows and now i officially conclude that this is a hard-ware related issue with my Laptop speakers. Reason: The error occurs in my installed Debian Linux, an Ubuntu Live distribution and Windows XP No error-message appears in all of the OS. The sound just keeps running and i can't hear a thing. I tested different setups, including OSS, ALSA and the pulseaudio server on top If i use my new usb-headphones i can hear sound all the time without any sudden silences. So obviously, although hard to believe, my laptop speakers are not okay (never heard of similar cases). I'll award the bounty to anyone who can point me to good tutorials or the procedure how to exchange my T410 speakers (i still have warranty. The laptop was bought in Germany, but now i am in Denmark). Or to someone who can explain me the output from hda-analyzer (big log above).

  • Is it possible to add "assert" as a keyword in Delphi?

    - by stanleyxu2005
    I write couple of "assert(...)" in code, to make sure that pre- and post-conditions should be satisfied. We can tell the Delphi compiler, whether to compile with assertions in a debug version and without assertions in a release version. I would like to know, if it is possible, to highlight "assert" like other Pascal keywords?

  • Translate COM error codes in C#

    - by Paul Keister
    In C, Pascal, and C++ it is possible to use the FormatMessage function to retrieve a "friendly" error message that corresponds to a COM HRESULT error code. This question contains sample code that demonstrates the C++ approach. Of course it would be possible to build a managed C++ assembly to perform this function for C# and VB.NET code, but I'm wondering: is there a way to translate COM error codes using the .NET system libraries?

  • Visual studio ORM designer option

    - by stackoverflowuser
    linq to sql visual studio Object-Relational designer generates C# entity class names same as the table names (except pluralizing it). so if the table name is authors it generates entity class with name "author". If the table name is Customers it generates class with name "Customer". Is there any option that can be set to make the designer generate entity class names as pascal cased. I am using VS 2010 if that makes any difference. Thanks.

  • What is the naming convention in Python for variable and function names?

    - by Ray Vega
    Coming from a C# background the naming convention for variables and method names are usually either CamelCase or Pascal Case: // C# example string thisIsMyVariable = "a" public void ThisIsMyMethod() In Python, I have seen the above but I have also seen underscores being used: # python example this_is_my_variable = 'a' def this_is_my_function(): Is there a more preferable, definitive coding style for Python?
