  • Necessary Infrastructure for large project with many components communicating through IPCs

    - by jluzwick
    I have a fairly in depth question which probably doesn't have an exact answer. As a software engineer, I am usually tasked with working on a program or project with minimal understanding of how other components or programs in the project interact with each other. When one program fails in a sea of multiple components and processes, what infrastructure elements are necessary to ensure that the problem can be accurately tracked to the violating application? More specifically, what infrastructure elements should be necessary for this large project and which are optional but very helpful. One such example I can think of is some form of a common logging infrastructure that allows for a developer or tester to easily browse through a log that contains numerous components for messages that might allude to the culprit program along with a "trail" of what happened before the issue occurred. I'm thinking of something similar to Androids alogcat tool. These necessary infrastructure elements should be language-agnostic. While these elements should be understood by all engineers on the team in question, which elements should be understood at great detail by the technical system engineers and what should the individual software engineers be responsible for adding to their tools to allow for such infrastructures to take hold? Please feel free to ask for clarification if something does not make sense as I understand this question is very broad and needs some refinement. I will refine as necessary from the answers and comments I receive. Thanks for any help!

  • How steep is the learning curve when moving from shared (cPanel) webhosting to a VPS (e.g. Linode)?

    - by pax
    In all shared hosting environments, one can be agnostic to the running OS. What happens in the case of Linode? I know it allows pretty flexible Linux installations, but for starters, besides choosing a distro, does one need to do more Linux sysadmin stuff besides the basic web hosting (DNS management, MySql database creations, users ftp/ssh access/ backups)? Does Linode have a module that would cover cPanel's basic features? Does one need to install/start/upgrade each aspect of LAMP (software bundle)?

  • Airpot Express configuration

    - by Christina
    We are trying to set up remote access to a computer that houses a server fro a particular program we are running. The program says we need to configure the office router. In the firewall settings it says to open ports 5345-5351 (TCP only). Port Forwarding: You will also need to forward the same range of ports (5345-5351) to the computer running the Server. This typically requires that the computer running the Server be assigned a static IP on the local network. Having trouble figuring out which IP address we actually need to be using on the client side of this program in order to access the server computer. Can someone walk through this process?? We are working on Mac OSX 10.5. Thank you in advance!

  • Can I autologin a specific user on a specific VT, but still have other login shells running?

    - by Michael
    I'm running a linux system with Ubuntu Karmic on it, and I use it to run a webcam and a program that continuously outputs on the console. Is there any way I can force a user to login on VT2, and then switch VTs to VT2, but still have other login consoles running so I can hook a keyboard up to it and CTRL-ALT-F# to get to another terminal? I have a feeling this needs to go in my rc.local file, but nothing in the login manpage seems to suggest it can do what I want it to do. If there is no way to login a user on the vt, launching the program directly on a specific VT will work as well, since the user's shell in /etc/passwd is set to the program anyway.

  • Automatically send a string when opening a raw connection in putty

    - by MBraedley
    I have a program running on a server that accepts TCP/IP connections on a specified port. When a connection is made, this program waits for the user (i.e. me) to send a string which identifies the type of user. Once the user identifies themselves, the program will start sending data that is relevant to that user type. I want to automate the first step and have putty automatically send the user identification string once the connection is made. I've been through the settings, and can't seem to find anything like "send following commands on connection". Any help would be appreciated.

  • Totem crashes immediately after startup in 12.10

    - by Sakib Hasan
    I did a fresh install of Ubuntu 12.10 and did sudo apt-get update && sudo apt-get update. Then I installed ubuntu-restricted-extras, audacious and vlc from Software Center. After that I tried launch Totem Movie player but in terminal following error comes up: (totem:9295): Gdk-ERROR **: The program 'totem' received an X Window System error. This probably reflects a bug in the program. The error was 'BadDrawable (invalid Pixmap or Window parameter)'. (Details: serial 1808 error_code 9 request_code 152 minor_code 9) (Note to programmers: normally, X errors are reported asynchronously; that is, you will receive the error a while after causing it. To debug your program, run it with the GDK_SYNCHRONIZE environment variable to change this behavior. You can then get a meaningful backtrace from your debugger if you break on the gdk_x_error() function.) Trace/breakpoint trap (core dumped) I tried purge and again install. But the error remains. What should I do?

  • Find methods related to testcases in Java

    - by user3623718
    I want to automatically change some methods in the program. These methods contain some compiler error and my program aims to fix these compiler errors. After fixing compiler errors I need to run test cases related to the changed method (or class) to know it is correct and if not which test cases failed. As the programs under investigation are very big, I only need to run test cases related to changes. As an example, if I change one method, then I need to only run test cases related to this method. Therefore, what I need is to programmatically be able to find test cases related to each method, and class. It is also useful if there is a tool that can do that for me. As an example, a tool which creates a matrix shows each test case is related to which method(s) One easy way to do that is to run all test cases and save functions they accessed. However, the problem is at the beginning the input program contains compiler error and it is not possible to run test cases because of these compiler error. Please let me know what is the best way to do that. An API or a tool that I can be used programmatically is the best for me.

  • is wisdom of what happens 'behind scenes' (in compiler, external DLLs etc.) important?

    - by I_Question_Things_Deeply
    I have been a computer-fanatic for almost a decade now. I've always loved and wondered how computers work, even from the purest, lowest hardware level to the very smallest pixel on the screen, and all the software around that. That seems to be my problem though ... as I try to write code (I'm pretty fluent at C++) I always sit there enormous amounts of time in front of a text-editor wondering how every line, statement, datum, function, etc. will correspond to every Assembly and machine instruction performed to do absolutely everything necessary for the kernel to allocate memory to run my compiled program, and all of the other hardware being used as well. For example ... I would write cout << "Before memory changed" << endl; and run the debugger to get the Assembly for this, and then try and reverse disassemble the Assembly to machine code based on my ISA, and then research every .dll, library file, linked library, linking process, linker source code of the program, the make file, the kernel I'm using's steps of processing this compilation, the hardware's part aside from the processor (e.g. video card, sound card, chipset, cache latency, byte-sized registers, calling convention use, DDR3 RAM and disk drive, filesystem functioning and so many other things). Am I going about programming wrong? I mean I feel I should know everything that goes on underneath English syntax on a computer program. But the problem is that the more I research every little thing the less I actually accomplish at all. I can never finish anything because of this mentality, yet I feel compelled to know everything... what should I do?

  • Changing the Default Install Location of an MSI

    - by PSteele
    A few months ago, I had to tweak an MSI installer.  It was installing into a specific directory (named the same as the application) underneath Program Files.  Since the location of Program Files can change from machine to machine, the MSI has a special token you can use for Program Files (as well as for the application name).  So the current value for “DefaultLocation” of the Application Folder was: [ProgramFilesFolder]\[ProductName] During installation, these tokens would be replaced by the actual location based on the current machine. I needed to change this to a specific folder underneath the users My Documents directory.  I poked around the help file and I could not find where these special tokens (like “[ProgramFilesFolder]”) were defined.  Obviously, there must be some specific set of values that are available and I’m sure My Documents is one of them. I finally found them documented so I’m posting the link here.  Hopefully, it will help someone else out.  Not sure where I found this link… System Folder Properties For me, it was as easy as changing the DefaultLocation to: [PersonalFolder]\MyToolName\Application Technorati Tags: .NET,MSI

  • Shader compile log depending on hardware

    - by dreta
    I'm done with the core of my graphics engine and I'm testing it on every platform I can get my hands on. Now, what I noticed is that different drivers return different shader and program compile log content. For example, on my friend's laptop if you successfuly compile a shader then the log is simply empty. However on my PC I get some useful information along with it. So if I compile a vertex shader, I'll get: Vertex shader was successfully compiled to run on hardware. Which isn't that impressive, but is what happens when I compile a program. On my friend's computer the log is empty, since the program compiles. However on my own computer I get: Vertex shader(s) linked, fragment shader(s) linked. Which is awesome, because I'm attaching a geometry shader with 0 (I have a geometry shader file with trash, so it doesn't compile and the pointer is set to 0), and the compiler just tells me which shaders linked. Now it got me thinking, if I was going to buy a graphics card, is there a way for me to get the information about whether or not I'll get this "extended" compile information? Maybe it's vendor specific? Now I don't expect an answer TBH, this seems a bit obscure, but maybe somebody has any experience with this and could post it.

  • Where in the registry are application registered hotkeys stored?

    - by Stuart Allen
    I need to find in the registry the key that is holding the hotkey CTRL-ALT-SHIFT-E. This is normally a keyboard shortcut in Photoshop, but I installed some program that did a global override of this sequence. I have uninstalled that program, but it did not clean up after itself. So, where can I find this in the registry, I just want to delete this key so the global override won't affect Photoshop anymore. I've google'd the crap out of this, there are various program that claim to assist, but none of them work.

  • Do we ethically have the right to use the MAC Address for verification purposes?

    - by Matt Ridge
    I am writing a program, or starting at the very beginning of it, and I am thinking of purchase verification systems as a final step. I will be catering to Macs, PCs, and possibly Linux if all is said and done. I will also be programming this for smartphones as well using C++ and Objective-C. (I am writing a blueprint before going head first into it) That being said, I am not asking for help on doing it yet, but what I’m looking for is a realistic measurement for what could be expected as a viable and ethical option for purchase verification systems. Apple through the Apple Store, and some other stores out there have their own "You bought it" check. I am looking to use a three prong verification system. Email/password 16 to 32 character serial number using alpha/numeric and symbols with Upper and lowercase variants. MAC Address. The first two are in my mind ok, but I have to ask on an ethical standpoint, is a MAC Address to lock the software to said hardware unethical, or is it smart? I understand if an Ethernet card changes if not part of the logic board, or if the logic board changes so does the MAC address, so if that changes it will have to be re-verified, but I have to ask with how everything is today... Is it ethical to actually use the MAC address as a validation key or no? Should I be forward with this kind of verification system or should I keep it hidden as a secret? Yes I know hackers and others will find ways of knowing what I am doing, but in reality this is why I am asking. I know no verification is foolproof, but making it so that its harder to break is something I've always been interested in, and learning how to program is bringing up these questions, because I don't want to assume one thing and find out it's not really accepted in the programming world as a "you shouldn't do that" maneuver... Thanks in advance... I know this is my first programming question, but I am just learning how to program, and I am just making sure I'm not breaking some ethical programmer credo I shouldn't...

  • Windows 7 PATH not expanding

    I am using the following to create and edit environment variables for Windows 7. Control Panel\All Control Panel Items\System -> Advanced system settings -> Environment Variables Under System variables I have the following pertinant variables: PROG32=C:\Program Files (x86) REALDWG_SDK_DIR=%PROG32%\Autodesk\RealDWG 2011 Path=%REALDWG_SDK_DIR%;%PROG32%\Haskell\bin However, the following happens: C:\>echo %PROG32% C:\Program Files (x86) C:\>echo %Path% %REALDWG_SDK_DIR%;C:\Program Files (x86)\Haskell\bin Is it possible to have a chain of variables expand? If I rename Path to something else, I sometimes get the problem, and sometimes I don't.

  • Why is the "file" command get confused on .py files?

    - by pythonic metaphor
    I have several python modules that I've written. Randomly, I used file on this directory, and I was really surprised by what I saw. Here's the resulting count of what it thought the files were: 1 ASCII Java program text, with very long lines 1 a /bin/env python script text executable 1 a python script text executable 2 ASCII C++ program text 4 ASCII English text 18 ASCII Java program text That's strange! Any idea what's going on or why it seems to think python modules are very often java files? I'm using CentOS 5.2.

  • Simple C: atof giving wrong value [migrated]

    - by Doc
    I have a program that reads input from a singe line(string obviously) and organizes it into arrays. The problem I have is that at one point the program reads two different values and returns the first one twice. Initially I thought the program was reading the same value twice but when I tested it turned out that it got the correct one but is inputting the wrong one. for example Input: 2 0.90 0.75 0.7 0.65 sorry to snip it (while(fgets (string[test], sizeof(string[test]),ifp)) pch = strtok_r(NULL, " ", &prog); tem3 = atoi(pch); while (loop<tem3) { pch=strtok_r(NULL," ",&prog); venseatfloat[test][loop][DISCOUNT][OCCUPIED]=(float)atof(pch); printf("%f is discount\t",venseatfloat[test][loop][DISCOUNT][OCCUPIED]); pch=strtok_r(NULL, " ", &prog); strcpy(temp, pch); venseatfloat[test][loop][REGULAR][OCCUPIED]=(float)atof(pch); printf("%s is the string but %.3f is regular\n", temp ,venseatfloat[test][loop][DISCOUNT][OCCUPIED]); loop++; } output: >0.900000 is discount 0.75 is the string but 0.900 is regular >0.700000 is discount 0.65 is the string but 0.700 is regular What is going on?

  • Silverlight and WCF caching

    - by subodhnpushpak
    There are scenarios where Silverlight client calls WCF (or REST) service for data. Now, if the data is cached on the WCF layer, the calls can take considerable resources at the server if NOT cached. Keeping that in mind along with the fact that cache is an cross-cutting aspect, and therefore it should be as easy as possible to put Cache wherever required. The good thing about the solution is that it caches based on the inputs. The input can be basic type of any complex type. If input changes the data is fetched and then cached for further used. If same input is provided again, data id fetched from the cache. The cache logic itself is implemented as PostSharp aspect, and it is as easy as putting an attribute over service call to switch on cache. Notice how clean the code is:        [OperationContract]       [CacheOnArgs(typeof(int))] // based on actual value of cache        public string DoWork(int value)        {            return string.Format("You entered: {0} @ cached time {1}", value, System.DateTime.Now);        } The cache is implemented as POST Sharp as below 1: public override void OnInvocation(MethodInvocationEventArgs eventArgs) 2: { 3: try 4: { 5: object value = new object(); 6: object[] args = eventArgs.GetArgumentArray(); 7: if (args != null || args.Count() > 0) 8: { 9:   10: string key = string.Format("{0}_{1}", eventArgs.Method.Name, XMLUtility<object>.GetDataContractXml(args[0], null));// Compute the cache key (details omitted). 11:   12: 13: value = GetFromCache(key); 14: if (value == null) 15: { 16: eventArgs.Proceed(); 17: value = XMLUtility<object>.GetDataContractXml(eventArgs.ReturnValue, null); 18: value = eventArgs.ReturnValue; 19: AddToCache(key, value); 20: return; 21: } 22:   23:   24: Log(string.Format("Data returned from Cache {0}",value)); 25: eventArgs.ReturnValue = value; 26: } 27: } 28: catch (Exception ex) 29: { 30: //ApplicationLogger.LogException(ex.Message, Source.UtilityService); 31: } 32: } 33:   34: private object GetFromCache(string inputKey) { if (ServerConfig.CachingEnabled) { return WCFCache.Current[inputKey]; } return null; }private void AddToCache(string inputKey,object outputValue) 35: { 36: if (ServerConfig.CachingEnabled) 37: { 38: if (WCFCache.Current.CachedItemsNumber < ServerConfig.NumberOfCachedItems) 39: { 40: if (ServerConfig.SlidingExpirationTime <= 0 || ServerConfig.SlidingExpirationTime == int.MaxValue) 41: { 42: WCFCache.Current[inputKey] = outputValue; 43: } 44: else 45: { 46: WCFCache.Current.Insert(inputKey, outputValue, new TimeSpan(0, 0, ServerConfig.SlidingExpirationTime), true); 47:   48: // _bw.DoWork += bw_DoWork; 49: //string arg = string.Format("{0}|{1}", inputKey,outputValue); 50: //_bw.RunWorkerAsync(inputKey ); 51: } 52: } 53: } 54: }     The cache class can be extended to support Velocity / memcahe / Nache. the attribute can be used over REST services as well. Hope the above helps. Here is the code base for the same.   Please do provide your inputs / comments.
