  • how can i get the file permission of a directory with java

    - by user571652
    i try to check the permission granted to a directory in linux, i mean i have a directory with permission 755 berty@berty-laptop:~$ ls -l / |grep directory drwxr-xr-x 3 root root 4096 2011-01-10 12:33 directory how can i read that permission with java? I've tried using FilePermission but though i have a directory with all the permissions (777) the FilePermission class always returns an exception java.security.AccessControlException: Access denied (java.io.FilePermission /home/directory read) at java.security.AccessController.checkPermission(AccessController.java:103) at com.snippets.Check4DirectoryPermission.checker(Check4DirectoryPermission.java:50) at com.snippets.Check4DirectoryPermission.main(Check4DirectoryPermission.java:70) is there another way to do this?

  • Remote I/O costs with a Content Delivery Network

    - by x711Li
    As far as I know, the time complexity of scanning a directory and the amount of files in said directory are correlated due to I/O costs. Would the administrative costs of placing the files in a hashed directory tree for uploading/downloading files through a CDN API be worth it for the added efficiency? For instance, given a filename foo.mp3, the MD5 hash for this is 10ebb1120767e9de166e0f5905077cb1. Thus, storing foo.mp3 in ./10/eb/foo.mp3 would allow for less files per directory (assuming MD5 generates patterns with in Base36, this allows for 36^2 root directories with 36^2 subdirectories each and little chance of hash collision) Considering the directories themselves are not loaded, would the I/O costs of directory scanning still exist with direct uploading/downloading?

    - by Jamesaa
    I have a simple page structure like below /directory/subdir_1/index.php /directory/subdir_2/index.php .... (there are no other files in these directories) is it possible to have 'fake/pretty' urls for the above files as below? /directory/subdir_1 /directory/subdir_2 ... so this path would show whether the visitor typed that,/directory/subdir_2/ or /directory/subdir_2/index.php.

  • Script for creating directories and subdirectories on SBS 2008

    - by Rich Piedmont
    I have a small business server 2008 and have a directory named LAWFILES. I have a 6 digit file system (eg 106568) and I create a directory to store anything to do with the file (documents, outlook emails, PDFs, WAV files, ect.) I group 100 files in a 4 digit directory (eg 1065) for quicker access. My new years resolution is to organize these directories. I used to have a script the batch created directories and sub directories but it didn't work the last time I tried it (2 years ago). I would like to run a batch file that would ask for the 4 digit directory name (eg 1065) and then create that directory and 100 subdirectories (106500 - 106599) each of which contained subdirectories named "Documents," "Correspondence" & "Email-Voicemail" Can anyone suggest where I would go to find a scripting language that would be available to accomplish this? Thanks for the Help. Rich Piedmont

  • How to fix Windows 7 device removal notification loop

    - by Barry Kelly
    Bit of an odd one this. One of our PCs is getting caught in a loop some time after being turned on, usually after a USB storage device has been attached - sometimes an iPod, sometimes a GPS. Specifically, Windows Explorer starts showing a drive icon and letter (E:, as of right now) for the System partition (the small hidden one at the start of the boot drive). Then, the icon disappears. Then it reappears again. And disappears. It does this very quickly, at what looks like maybe 50 times a second. CPU usage in this loop is also very high; averages about 66%. This machine has an i7 920 CPU, which is quad core with hyperthreading; so this usage rate works out to about 5 100% busy threads, along with whatever normal idle load is (particularly Task Manager itself). Inspecting with Process Explorer shows that the device removal notification infrastructure has gone berserk. The threads in system service processes (i.e. apart from Windows Explorer) which are using all the CPU power relate to device notification. The Disk Management MMC snap-in also fails to run when the loop starts. The only way to break the loop, it seems, is to reboot the machine. Anyone seen anything similar to this, and know of a way to fix it? Machine details: Windows 7 x64, fully patched i7 920, 12GB RAM Intel SSD 80GB (X25-M, I believe; not G2) 2TB 5.2K disk for bulk storage AMD HD 5870 Further hardware details await. I'm going to go through and update all drivers I can find.

  • Hyper-V Manager - Host Access During a Catastrophe

    - by LonnieBest
    How can I ensure that I can always have Hyper-V Manager access to a Hyper-V server, even in the event that the Active Directory Server is down (in a domain-login environment)? Background: The one that came before me, set up the company's servers as virtual machines on top of a host running Hyper-V Server 6.1 (7601) Service Pack 1. For managing Hyper-V, he installed Window 7 onto a virtual machine (run on the same host) with Hyper-V Manager installed. When the (virtual) Active Directory server (run on this same host) is rebooted, during that reboot, I'm unable to RDP into the Windows 7 virtual machine, and I'm therefore unable to access Hyper-V Manager when the Active Directory server is down. I suspect I can't login because I can't authenticate with the Active Directory Server. I'm going to install Hyper-V Manger onto some addition manager's workstations, but how can I ensure they'll have access in a catastrophe where Active Directory authentication isn't possible?

  • Need to extract thousands of folders and mass rename files inside folder corresponding to folder title

    - by user140393
    I did a site rip with wget and all the files I want are arranged with a webid which I do not want for example site.com/ID/title It appears as so in the directory siteIDFoldernameFile It's just a single file labelled index.html for the 10k+ ID's So essentially I want to remove ID folder while preserving the folder (file) inside. Then I want to rename the index.html inside of foldername to replace index.html

  • installing Ubuntu 32 bit and Lubuntu 64 bit with the same home directories

    - by rakesh
    Mine is a 64 bit machine and I had installed "32" bit Ubuntu to try it out and hence installed many apps and developed many things and configured it for many things. Now it seems that my laptop needs more resources as my development needs so much. My question is :to free up install Lubuntu "64" bit in other partition which uses the same home directory and apps and my development rendering my laptop to be faster than before. Is this possible ? Thanks in Advance.

  • How do I force folder view sort order to not ignore special characters?

    - by Jason Hartley
    I have many folders in my home directory that have names that begin with special characters such as _OLD_500GB_HD or !FolderIWantToSeeAtTheTop, but for some reason these folders are sorted according to their first alphanumeric character rather than the leading special character. So how can I force the folder to not ignore the special character, or how else can I make the sort view organize certain folders at the top or bottom of the sort? Thanks.

  • I have a global .gitignore but files aren't being ignored, why?

    - by Michael Durrant
    I have a .gitignore_global in my home directory durrantm.../durrantm$ pwd /home/durrantm durrantm.../durrantm$ ls .git* .gitconfig .gitignore_global The .gitignore_global has: durrantm.../durrantm$ head .gitignore_global # RubyMine # .idea/ # Compiled source # ################### *.dll *.exe # Logs and databases # ###################### but when I git status for a project I still end up getting the .idea files when I start using rubyMine.

  • My home folder disappeared after using Chroot/debootstrap. Can it be recovered?

    - by Martin
    I was following the instructions from http://wiki.winehq.org/WineOn64bit but stopped after cloning wine. Afterwards I closed the terminal and terminated the process when asked. Ubuntu threw up an error report and when I tried to cd to ~/Downloads it was gone, along with all the other directories. So I tried restarting Ubuntu, whereupon I was greeted with the default desktop and home directory. Can I recover my home folder or has it been deleted?

  • on SSH login, get message 'Could not chdir to home directory"

    - by joachim
    I am SSHing into a Mac OS X server running Tiger. When I log in I get put in the root directory and shown this message: Could not chdir to home directory : No such file or directory My $HOME variable seems to be empty. I've googled the problem and found a mailing list thread which suggests using dscl to set up the home directory, but I've done that and the problem still persists even though now dscl correctly reports: $ dscl . -read /users/me NFSHomeDirectory NFSHomeDirectory: /Users/me

  • Specifying an additional Applications directory on Mac OS X

    - by 341008
    Is there any way I can specify an additional Applications directory. I basically want to keep the applications that come with Mac OS X in the default Applications directory, but, install all third-party software to a different directory which is in a separate partition. I want to retain all advantages of the actual Applications directory such as the one where copying files from a .dmg to the Applications folder installs software.

  • Sync local directory with remote FTPS?

    - by A T
    How do I keep my local directory in sync with my remote FTPS directory? Note that I've tried WinSCP, but found that it only works a few times then I need to restart it to get it going again. Also I've tried all the utilities mentioned here but only a few supported the connection requirements (explicit SSL over FTP), and those that did didn't have "realtime" directory sync. Also note that a curl, rsync or wput command which I can put into "scheduled tasks" will suffice, if it can do directory sync.

  • What's the correct SELinux type for a directory?

    - by unthar
    If I create a new filesystem/directory off of / and I set the Linux permissions to 770 I expect the group to be able to read and write files in that directory. SELinux was preventing me from doing this until I changed the SELinux type on that directory to public_content_rw_t. If this is just a directory in which users in that group will share files is this an acceptable SELinux type or should I be using another one? Writing a custom policy seems like overkill for these purposes. Thanks

  • How to access the relative directory of a ASP.NET website?

    - by Michael Schilling
    I need to access a folder that will contain various text files for my web site. I'm using Visual Web Developer 2010 Express. I made a web site using visual basic. Here is the failing code: Dim fileName As String fileName = CurDir.ToString + fileName.Text + ".txt" FileOpen(1, fileName, OpenMode.Output) FileClose(1) CurDir.ToString is giving me strange directory path that isn't anywhere near where my website files are located. I need to be able to access the files in a folder inside of the WebSite1 folder without using C:\Users\..., but I'm at a loss on how to do that. Can anyone help me out?

  • Can a user be a member of multiple Organization Units (OU) in Active Directory ?

    - by Stormshadow
    Can a user be a member of multiple Organization Units (OU) in Active Directory ? Also, is there a standard format mentioned by Microsoft on how an OU should be created and what its attributes are ? I found this in Wikipedia "However, Organizational Units are just an abstraction for the administrator, and do not function as true containers; the underlying domain operates as if objects were all created in a simple flat-file structure, without any OUs. It is not possible for example to create two user accounts with an identical username in two separate OUs, such as "fred.staff-ou.domain" and "fred.student-ou.domain"."

    I'm gonna make a game and I think C++ would be perfect for it. I think I'm gonna use SDL and OpenGL but I need help with making the code manageable. These were my ideas: 1. Making A DLL File With Commands Such A CreateScreen(640, 480); Which Binds SDL And OpenGL Commands For A Manageable Setup 2. Making It Harder To Mod (Like UnCompiling My Code) Like Encrypting Save Files That Only My Program Can Read Any Suggestions?

  • Event-based server-gameloop in a server based game

    - by Chris
    I know that this site is full of questions about fixed gameloops and variable gameloops and different types of threading. But I coult find barely nothing that is related to server loops. The server has no screen to draw on. It could just run as fast as possible, but of course this makes no sense. But should it really use single "ticks" and send the updates periodically after each tick and wait for the next "tick" to update its state. Is it applicable to replace the gameloop by multilpe events? Suchs as incoming network traffic or timers? I often heared that a gameloop should be determistic, but does it really matter? For instance, when you play a shooter game against humand players and/or AI you proably would never be ably to repeat the same input twice. Is it a good idea to lose determistic behavior if it is nearly impossible to reprodruce the same input twice? So this question is more or less about whether an strictly event-based gameloop is adviseable or not and what are the pros and cons. I could imagene that an event-based gameloop could perform much faster and smoother, since you don't have bug CPU-spikes during the beginning of a new "tick". The fact that I could not find much about an event-based gameloop for servers leads me to the conclusion that inefficient or too complicated to get a real benefit from it. I'm sure if this is enough to get an idea from what I'm interessted to know, but I hope so.

  • Combining Scrum, TFS2010 and Email to keep everyone in the loop

    - by Martin Hinshelwood
    Often you will receive rich information from your Product Owner (Customer) about tasks. That information can be in the form of Word documents, HTML Emails and Pictures, but you generally receive them in the context of an Email. You need to keep these so your Team can refer to it later, and so you can send a “done” when the task has been completed. This preserves the “history” of the task and allows you to keep relevant partied included in any future conversation. At SSW we keep the original email so that we can reply Done and delete the email. But keeping it in your email does not help other members of the team if they complete the task and need to send the “done”. Worse yet, the description field in Team Foundation Server 2010 (TFS 2010) does not support HTML and images, nor does the default task template support an “interested parties” or CC field. You can attach this content manually, but it can be time consuming. Figure: Description only supports plain text, and History supports HTML with no images   What should we do? At SSW we always follow the rules, and it just so happened that we have rules to both achieve this, and to make it easier. You should follow the existing Rules to Better Project Management  and attach the email to your task so you can refer to and reply to it later when you close the task: Do you know what Outlook add-ins you need? Describe the work item request in an email Use Outlook Add-in to move the email to a TFS Work Item When replying to an email with “done” you should follow: Do you update Team Companion template, so the email "subject" doesn't change? Do you update Team Companion template, so you can generate a proper "done" mail? Following these simple rules will help your Product Owner understand you better, and allow your team to more effectively collaborate with each other. An added bonus is that as we are keeping the email history in sync with TFS. When you “reply all” to the email all of the interested partied to the Task are also included. This notified those that may have been blocked by your task to keep up to date with its status. This has been published as Do you know to ensure that relevant emails are attached to tasks in our Rules to Better Scrum using TFS. What could we do better? I would like to see this process automated so that we capture the information correctly in the task without the need to use email. This would require a change to the process template in Team Foundation Server to add an “Interested Parties” field. Each reply to the email would need to be automatically processed into a Work Item. This could be done by adding a task identifier as the first item in the “Relates to” email header, and copying in an email address that you watch. This would then parse out the relevant information and add the new message to the history, update the “Interested parties” field and attach the Images. Upon reflection, it may even be possible, but more difficult to do this using ONLY the History field and including some of the header information in there to the build a done email with history. This would not currently deal with email “forks” well, but I think it would be adequate for our needs. It would be nice if we could find time to implement this, but currently it is but a pipe dream. Maybe Microsoft could implement something in the next version of Team Foundation Server, and in the mean time we have a process that works well. Technorati Tags: Scrum,SSW Rules,TFS 2010,TFS 2008

  • Calculating Delta time , what is wrong?

    - by SteveL
    For 2 days now i am trying to calculate the correct delta time for my game , I am starting to getting crazy since i tried all the solutions that i found on the 5 first google pages... What is wrong? I cant get the correct delta time ,whatever i tried is just not working , the delta goes from 1 to 4 and then back 1 and then to 3 even if i take the averange delta between many frames.Plus the game runs way much faster(i mean the movement) on slow devices than in fast. The game runs on android so the spikes between frames are expected. My code is this: void Game::render() { timesincestart=getTimeMil(); _director->Render(); _director->Update(); float dif=(getTimeMil()-timesincestart);//usally its about 5 milliseconds lastcheck++; sumdelta+=dif; if(lastcheck>20) { sumdelta=sumdelta/20; delta=sumdelta; sumdelta=0; lastcheck=0; } LOGI("delta:%f",delta); }

  • Implementation of Race Game Tree

    - by Mert Toka
    I build a racing game right in OpenGL using Glut, and I'm a bit lost in all the details. First of all, any suggestions as a road map would be more than great. So far what I thought is this: Tree implementation for transformations. Simulated dynamics.(*) Octree implementation for collusion detection. Actual collusion detection.(*) Modelling in Maya and export them as .OBJs. Polishing the game with GLSL or something like that for graphics quality. (*): I am not sure the order of these two. So I started with the simulated dynamics without tree, and it turned out to be a huge chaos for me. Is there any way you can think of such that could help me to build such tree to use in racing game? I thought something like this but I have no idea how to implement it. Reds are static, yellows are dynamic nodes
