  • Overcrowded Windows XP Folders

    - by BlairHippo
    I know that, technically, an individual Windows XP directory can hold an immense number of files (over 4.29 billion, according to a quick Google search). However, is there a practical ceiling where too many files in one directory starts having an impact on reads to those files? If so, what factors would exacerbate or help the issue? I ask because my employer has several hundred XP machines in the field at client sites, and the performance on some of the older ones is getting "sludgy." The machines download and display client-defined images, and my supervisor and I suspect that our slacktastic approach to cache management could be to blame. (Some of the directories have tens of thousands of images in them.) I'm trying to gather evidence to support or contest the theory before spending time on a coding fix.

  • iOS App with OCMaps crashes when using the phone in chinese Language

    - by Pedro Morte Rolo
    I've been given the task of doing maintenance to a iOS application that uses OCMapView. I have just realized that when using the application in chinese language, it blows up when the selector doClustering is invoked on a OCMapView instance. This is for me a very puzzling behaviour, because I thought that regardless of the environment language, the OCMapView class should allways have the same methods. Am I wrong? Do you have any recomentations about how to find a solution to this problem? Thank you, Pedro

  • Socks5 proxy "Dante" leaves many child processes stuck in FIN_WAIT2 / CLOSE_WAIT state

    - by Asad R.
    I'm running dante v1.2.1 as a SOCKS proxy server. The proxy works fine but at the end of the day there are around 40-50 or more child processes of sockd running even though there are no active connections. lsof shows that the child processes all have sockets in the CLOSE_WAIT and FIN_WAIT2 state. These child processes stay in this state unless I manually killall/restart the daemon. I'm running Gentoo Linux on a 2.6.24-23-xen kernel. I recently upgraded from dante v1.1.19-r4 which was giving me the exact same problem. Is this a configuration issue with Dante, my system, or is it a coding issue in the dante code?

  • Windows - put HDD stand-by and sleep mode

    - by iulianchira
    How can I put a hard disk drive in stand-by or sleep mode in Windows, in a programmatic manner. Does the Windows API or any .Net libraries provide any functions to achieve this? (I am aware that I should probably not interfere with Windows's power management mechanism, but this is not something I intend to use in a production environment, it is a proof of concept for some algorithms).

  • How to align text at the top left-hand corner?

    - by OverTheRainbow
    I'd like to use stylesheet instead of hard-coding HTML so that text within cells are aligned vertically, ie. text starts at the upper left-hand corner. However, neither of this works: <head> <link rel="STYLESHEET" href="display.css" type="text/css"> <style> td {vertical-align:top; font-size:x-small} td {vertical-align:text-top; font-size:x-small} </style> </head> Does someone know? Thank you. Edit: Problem solved. Turns out the HTML editor I'm using is a bit old and didn't display things as expected, but they do show OK in a modern browser with "vertical-align:top".

  • Can the Microsoft Paint Edit Colors Dialog be supplemented?

    - by Gus
    I have written a WinForms application that presents a color picker, limited to the known colors. My environment is Visual Studio C# Express 2008, C#, and Framework 2.0. Currently the MS Paint Colors menu item only presents an Edit Colors dialog. I would like to supplement that by causing the Colors menu item to display both "Edit Colors" and "Edit Known Colors". Can I accomplish this? If so, please provide a citation (or code if preferrred).

  • Unit testing Jade

    - by Strawberry
    Hi, What techniques and design strategies have people used to aid in unit testing Jade applications? In particular, how do people typically go about testing Behaviours - which are tightly coupled to the Agent instance and the Jade environment? I'm aware of the JadeMX project, but this appears to be geared more towards system testing - in particular the message exchange between collaborating agents. Thanks.

    I have a win32 GUI (MFC) application which I need to port to a WIN CE environment. I keep encountering undefined identifiers. What is the best way to deal with this- is there some site where i can get a mapping of some kind between win32 supported features and corresponding wince features (even if they are not supported, the information that they are not is valuable)

  • TextMate - must have Plugins(web devel)

    - by dscher
    Just curious what experienced Textmate users can't live without in the program. I just ran the trial and bought the program so I'm trying to get a sense of how others might setup their development environment for web development. Also, based on the fact that I just bought the program, I am going to guess that TM2 will come out next week. Yes, that's right, next week. Unfortunately, because of my luck, it will not be a free upgrade...upgrades will cost more.

    Is there any way to add any sort of debugging to a Lego Mindstorms program, when using the NXT drag-and-drop environment? It would be nice to be able to monitor the status of the various sensors, but even knowing what step in the program was running would be nice.
