  • Store system passwords with easy and secure access

    - by CodeShining
    I'm having to handle several VPS/services and I always set passwords to be different and random. What kind of storage do you suggest to keep these passwords safe and let me access them easily? These passwords are used for services like databases, webserver user and so on that run customers' services, so it's really important to keep them in a safe place and strong. I'm actually storing them in a google drive spreadsheet file, describing user, password, role, service. Do you know of better solutions? I'd like to keep them on a remote service to make sure I don't have to make backup copies (in case my hdd would fail somehow). I do work on *nix platforms (so windows specific solutions are not a choice here).

  • Do you code variables in your language?

    - by Phil Hannent
    I am just working on a project where the library has an object with the property color, however being British I always use colour when writing variables and properties. I also just found some legacy code where the British developer used color in a variable name. Is American English the default for development now?

  • Behaviour of System.Timer when Interval property changed

    - by lowlyintern
    I have a System.Timer setup to trigger an event every day at 2AM. If the process the timer starts fails then I want the timer to be reset to run every 15 minutes until the process completes succesfully. // this is how the timer is set up. // this is working correctly. double startTime = milliseconds_of_hour_to_start. Timer = new System.Timers.Timer( startTime); Here is the code to reset the timer on success or failure of the event handler. NOTE the timer is not being stopped, just the Interval property is being reset. if (ProcessSuccess) { Timer.Interval = TimeSpan.FromHours(24).TotalMilliseconds; } else { Timer.Interval = TimeSpan.FromMinutes(15).TotalMilliseconds; } My question is this, if the process fails say 4 times, then succeeds will the Timer now be running at around 3AM? i.e. after failing will the original start time of 2AM be advanced by 15 minutes?

  • Measuring execution time of a call to system() in C++

    - by jm1234567890
    I have found some code on measuring execution time here http://www.dreamincode.net/forums/index.php?showtopic=24685 However, it does not seem to work for calls to system(). I imagine this is because the execution jumps out of the current process. clock_t begin=clock(); system(something); clock_t end=clock(); cout<<"Execution time: "<<diffclock(end,begin)<<" s."<<endl; Then double diffclock(clock_t clock1,clock_t clock2) { double diffticks=clock1-clock2; double diffms=(diffticks)/(CLOCKS_PER_SEC); return diffms; } However this always returns 0 seconds... Is there another method that will work? Also, this is in Linux. Thanks!

  • Parallelism on two duo-core processor system

    - by Qin
    I wrote a Java program that draw the Mandelbrot image. To make it interesting, I divided the for loop that calculates the color of each pixel into 2 halves; each half will be executed as a thread thus parallelizing the task. On a two core one cpu system, the performance of using two thread approach vs just one main thread is nearly two fold. My question is on a two dual-core processor system, will the parallelized task be split among different processor instead of just utilize the two core on one processor? I suppose the former scenario will be slower than the latter one simply because the latency of communicating between 2 CPU over the motherboard wires. Any ideas? Thanks

  • system-wide hook for 64-bit operating systems

    - by strDisplayName
    Hey everybody I want to perform a system-wide hook (using SetWindowHook) on a 64bit operating system. I know that 64bit processes (= proc64) can load only 64bit dlls (= dll64) and 32bit processes (= proc32) can load only 32bit dlls (= dll32). Currently I am planning to call SetWindowHook twice, once with dll32 and once with dll64, expecting that proc64s will load dll64 and proc32s will load dll32 (while dll32 for proc64s and dll64 for proc32s will fail). Is that the correct way to do that, or is there a "more correct" way to do that? Thanks! :-)

  • Multi language testing framework

    - by santiiiii
    I need to write two versions of the same application, one in .NET and the other one in Java. So I'd like to write a single test suite, and then use it against both codebases. Which testing tool would you advise me to use?

  • function in c language

    - by sandy101
    Hello, I am practice the function in c and come across to the program .... include int main() { float a=15.5; char ch ='C'; printit(a,ch); return 0; } printit(a,ch) { printf("%f\n%c",a,ch); } I want to know that why the above program compile and not give the error as i understood so for is ... 1) The function in c must be declared with the specific prototype (but this program does not contain the prototype ) 2)why the program give the output 'x'for the char variable 3)can the function in c are capable of accepting the value without being declared about type in parameters like what has done in the function declaration .... plz.... help

  • What language is this?

    - by Blue
    got some keys with patterns like 4AC59BAA63A64327DCE12C0B2CD1A397 and B9E685495FECFC9854E7DBA508D91213 they have 32 chars and i would like not to decrypt then but to be able to make my own, its something like a hash of a file

  • Application wide messaging... without singletons?

    - by StormianRootSolver
    So, I want to go for a more Singleton - less design in the future. However, there seem to be a lot of tasks in an application that can't be done in meaningful way without singletons. I call them "application wide services", but they also fall into the same category as the cross cutting concerns, which I usually fix via AOP. Lets take an example: I want an application wide message queue that dispatches messages to components, every component can subscribe and publish there, it's a very nice multicast thing. The message queue and dispatching system are usually a (rather short) singleton class, which is very easy to implement in, say, C#. You can even use double dispatching and utilize message type metadata and the like, it's all so easy to do, it's almost trivial. However, having singletons is not really "object oriented design" (it introduces global variables) and it makes testing harder. Do you have any ideas? I'm asking this question because I'm willing to learn more about this topic, a LOT more. :-)

  • Why is there "data" and "newtype" in Haskell?

    - by martingw
    To me it seems that a newtype definition is just a data definition that obeys some restrictions (only one constructor and such), and that due to these restrictions the runtime system can handle newtypes more efficiently. Ok, and the handling of pattern matching for undefined values is slightly different. But suppose Haskell would only knew data definitions, no newtypes: Couldn't the compiler find out for himself whether a given data definition obeys these restrictions, and automatically treat it more efficiently? I'm sure I'm missing out on something, these Haskell designers are so clever, there must be some deeper reason for this...

  • File System Types in .Net

    - by Avi
    I don't get the abstractions and the terminology :-( For example, DirectoryInfo.FullName is defined as the full path of the directory or file, but it's a string! So is DirectoryInfo.Name, FileInfo.FullName, Path.GetDirectoyName and so on. This means that in .Net there is no "depth" (or "meat" - my English isn't so good) for the file system objects. There's no protection from a type system. I can't, for example, define two Path objects and ask if one of them is "above" the other - I have to manipulate the strings. I can't differentiate between a Path that identifies a directory and a path that identifies a file. I can't do anything!-( Just manipulate strings. Is this correct (or am I simply missing something). If correct, are there any alternatives?

  • Language restrictions on iPhone lifted?

    - by John Smith
    Apparently Apple has changed some term in the agreement again. From http://www.appleoutsider.com/2010/06/10/hello-lua/ section 3.3.2 is now Unless otherwise approved by Apple in writing, no interpreted code may be downloaded or used in an Application except for code that is interpreted and run by Apple’s Documented APIs and built-in interpreter(s). Notwithstanding the foregoing, with Apple’s prior written consent, an Application may use embedded interpreted code in a limited way if such use is solely for providing minor features or functionality that are consistent with the intended and advertised purpose of the Application. instead of the original No interpreted code may be downloaded or used in an Application except for code that is interpreted and run by Apple’s Documented APIs and built-in interpreter(s). I am more interested in embedding Lua, but other people have other embeddings they want to make. I am wondering how you ask for permission, and what they mean by the terms "minor features" and "consistent" and how will Apple interpret this section? It seems to have enough loopholes to drive a real firetruck through.

  • How to pass parameters with spaces via cstdlib system

    - by buchtak
    Hi, I have this windows console app which takes a file, do some calculations, and then writes the output to a specified file. The input is specified in "app.exe -input fullfilename" format. I need to call this application from my C++ program, but I have a problem with spaces in paths to files. When I call the app directly from cmd.exe by typing (without specifying output file for clarity) "c:\first path\app.exe" -input "c:\second path\input.file" everything works as expected. But, when I try using cstdlib std::system() function, i.e. std::system(" \"c:\\first path\\app.exe\" -input \"c:\\second path\\input.file\" "); the console prints out that c:\first is not any valid command. It's probably common mistake and has simple solution, but I have been unable to find any. Thx for any help.

  • Multiple System.Web.Extensions assembly in same project?

    - by CL4NCY
    Hi, I'm having trouble moving a website from one server to another. It seems to be a problem loading multiple versions of System.Web.Extensions. The code uses version 3.5 in most places but a third party control appears to be needing version 1.0.6. I didn't think this was possible but it appears to be working in it's current situation. Is there a way I can use the GAC version of System.Web.Extensions for the site but import a dll of version 1.0.6 just for these controls?

  • Mac OS X - detect file system read

    - by quano
    I want to know what files a specific application is trying to access on my disk. I know that you can use fs_usage, but this outputs events from all applications. I know that you can target a single application, but only one that is already running. I want to detect all readfile-events an application is trying to do, ever since it is started. I don't want to miss out on any event. How do you achieve this?
