  • Need some advice on CLI design, I need to provide simple but powerful command line options

    - by howtechstuffworks
    I am writing a utility that runs on RHEL5 command line. I need my command line options to be simple but powerful. I looked at the various UNIX utilities to get an idea of how simple command line utilities have to be. Do you guys suggest any documents/links that talk about command line etiquette? I am modelling my utility on top of LVM (that's all the info I can give for now). I know it's a software engineering question, but I thought it would be appropriate to post here. Please advise.... PS: I am not asking for details about getopt or command line utility parsers.....

Briefly describe the equipment: ASRock B75 Pro3-M i5 3330 GeForce GTX 650 Ti SATA 500GB running OS X Mavericks + Clover - a boot disk Toshiba 2TB running Windows 8.1 (x64) and Ubuntu 14.04 (amd64) If you boot from the Toshiba (where there is Ubuntu and boot Windows + GRAB) after restart boot from Clover, it is impossible. Tried a lot of options - as Clover installation and boot priority, and various settings Grab, but have not found an acceptable option and reinstall again Clover - no desire ( Mavericks 20 seconds reboots - excellent !) So please help on the file system - how to convert to XFS HFS + magazine . Mavericks to saw it all synced on Mac . Thank you for the sensible answer and help! Originally in Russian.

  • Upgrade to Precise leaving system unbootable

    - by Talemon
    I've upgraded our server's system from Lucid to Precise and as far as I can tell, it left the system in an un-bootable state. I've read many responses in different threads but my problem has a twist. When we boot the server, it says The disc drive for / is not ready yet or not present Continue to wait; or press S to skip mounting or M for manual recovery but when I press any of those buttons, it doesn't do anything. I can't boot to any recovery console, and as it is a server and I'm accessing it via iDRAC, there's not much I can do.

  • Why is the System process listening on Port 443?

    - by ClearsTheScreen
    I am having problems starting my apache server, because port 443 is already in use. It turns out, the system process (PID 4) uses the port 443. I don't have IIS installed, the services.msc shows (predicatbly) no Exchange server running, nor WWW-Services, nor IIS. I have no idea how to find out what service uses that port short of just disabling each service one after the other, and I am not even sure that would help. I would be grateful if someone could point me towards how I can get my SSL port back, thank you :) P.S.: Of course "just switch apache to another port for SSL" would solve the problem of not being able to start apache. But I'd still like to know what is so insistent about hogging port 443. :)

  • Building an instance system.

    - by Kyle C
    I am looking into how to design an instance system for the game I am working on. I have always wondered how these are created in games like World of Warcraft, where instances == dungeons/raids/etc). Areas that are separated from players other than those in your group, but have specific logic to them. Specifically how can you reuse your existing code base and not have a bunch of checks everywhere ? if (isInstance) do x; else do y; I don't know if this will make too much of a difference on any answers, but we're using a pretty classic "Object as pure aggregation" component system for our entities.

  • Installing multi-boot Linux system

    - by user94924
    I have a dual (XP/Linux) boot Compaq Presario S4500UK with a couple of spare partitions on the boot drive which I want to use for testing different Linux distros/configs before installing them on "live" machines. I tried this with Oneiric which worked fine until I came to uninstalling the test system. Fortunately Oneiric uses Grub2 and so redirecting the bootloader to work from the original Linux partition was a piece of cake - if a bit annoying. I now need to do some tests on Hardy and DSL (Damned Small Linux), neither of which use Grub2. Question: Is it possible to install a test operating system without adding/replacing the bootloader (ie so I can still use Grub2 from the original partition with its nice interface and recovery facilities)? Is there another way of uninstalling/decommisioning a test OS which doesn't trash the boot loader? (The only way I know to do this is by deleting/reformatting the partition which takes with it the bootloader which is in that partition). Any help would be much appreciated. Tks jg1

  • Stairway to Database Design STEP 2: Domains, Constraints and Defaults

    A clear understanding of SQL Data Types and domains is a fundamental requirement for the Database Developer, but it is not elementary. If you select the most appropriate data type, it can sidestep a variety of errors. Furthermore, if you then define the data domains as exactly as possible via constraints, you can catch a variety of those problems that would otherwise bedevil the work of the application programmer.

  • Interface design where functions need to be called in a specific sequence

    - by Vorac
    The task is to configure a piece of hardware within the device, according to some input specification. This should be achieved as follows: 1) Collect the configuration information. This can happen at different times and places. For example, module A and module B can both request (at different times) some resources from my module. Those 'resources' are actually what the configuration is. 2) After it is clear that no more requests are going to be realized, a startup command, giving a summary of the requested resources, needs to be sent to the hardware. 3) Only after that, can (and must) detailed configuration of said resources be done. 4) Also, only after 2), can (and must) routing of selected resources to the declared callers be done. A common cause for bugs, even for me, who wrote the thing, is mistaking this order. What naming conventions, designs or mechanisms can I employ to make the interface usable by someone who sees the code for the first time?

  • Design Better, Rich Internet Applications

    As you know, Rich Internet Applications are web-based software programs that behave and operate like a desktop application. These may be delivered through a site-specific browser, a browser plug-in, or through other methods; they are especially useful for massively-multiplayer online role-playing games (MMORPGs). RIA training can be especially useful in learning the tools that are used for designing and developing these increasingly-necessary additions to Internet Web Sites.

  • Thriving With Web Design and Development

    Web Designers and Developers seem to compete for projects, so it seems only natural to find the source of business from the start and hopefully bid and win the job over "the other guy". Other industry specialists such as Domain Investors and other Web Developers already have the projects and established capital, marketing plan, and usually a concept for their project or campaign and you better believe they need your assistance.

  • session persisting problem after system restart

    - by user100124
    Is there a way to prevent session id restore on startup/restart of user's system? We are using a asp.net app and I am able to login and access the site. For the first time session id is created and stored in cookies. Problem: But if I restart my system without signing out, the session is still alive. How can I prevent this? from server side. I can try to delete cookies but it is not practical, as each user will have different preferences.
