  • Data-related security Implementation

    - by devdude
    Using Shiro we have a great security framework embedded in our enterprise application running on GF. You define users, roles, permissions and we can control at any fine-grain level if a user can access the application, a certain page or even click a specific button. Is there a recipe or pattern, that allows on top of that, to restrict a user from seeing certain data ? Sample: You have a customer table for 3 factories (part of one company). An admin user can see all customer records, but the user at the local factory must not see any customer data of other factories (for whatever reason). Te security feature should be part of the role definition. Thanks for any input and ideas

  • Problems while applying an svn patch to a mercurial repository

    - by user26453
    Patch file is made with TopirtiseSVN - Create Patch... Attempting to import patch into the mercurial repository using hg import patchfile. The problem I'm running into is that there seems to be problems with how hg looks for files referenced in the patch file: unable to find 'gui/gui/RemoteFramework.cpp' for patching 2 out of 2 hunks FAILED -- saving rejects to file gui/gui/RemoteFramwork.cpp.rej Seems to be an issue of where the patch was made in terms of directories and where it should be applied. Have tried playing with the --base option for hg import, but haven't gotten anywhere just yet. Anyone have any tips?

  • Linq Grouping by 2 keys as a one

    - by Evgeny
    Hello! I write a simple OLAP viewer for my web-site. Here are the classes (abstract example): Employee { ID; Name; Roles[]; //What Employee can do } Order { Price; Employee Manager; Employee Executive; //Maybe wrong english. The person which perform order } Employee can be Manager and Executive in the order at the same time. This means that Employee role is not fixed. I have to group orders by employees and finally get IGrouping with Employee key. So .GroupBy(el=new {el.Manager,el.Executive}) is not allowed. I considered some tricks with IEqualityComparable, but found no solution. If somrbody will help I'll be vary glad, thank you.

  • VLC - Adding to playlist

    - by VANJ
    I am using Songr to find/stream songs and double click them to play in VLC which basically "plays" the URL. But as I am listening to one item and search for another and double click another item from the results, it replaces the currently playing item in VLC. How do I set it up such that double clicking adds to the current playlist? When I see now is that it adds the new item to the end of the playlist and proceeds to play it. Any ideas? Thanks

  • A simple explanation of Naive Bayes Classification

    - by Jaggerjack
    I am finding it hard to understand the process of Naive Bayes, and I was wondering if someone could explained it with a simple step by step process in English. I understand it takes comparisons by times occurred as a probability, but I have no idea how the training data is related to the actual dataset. Please give me an explanation of what role the training set plays. I am giving a very simple example for fruits here, like banana for example training set--- round-red round-orange oblong-yellow round-red dataset---- round-red round-orange round-red round-orange oblong-yellow round-red round-orange oblong-yellow oblong-yellow round-red

  • Will Dolphin emulator run (smoothly) on this machine?

    - by Mark
    Product Specs: Intel® NM10 Express chipset /w Intel® Atom® D525 (dual-core, 1.8 GHz) I think the most I can put in there for RAM is 4 GB. (They don't make 8 GB SODIMM do they?) The Dolphin site is pretty vague about requirements: Windows XP or higher, or Linux, or MacOSX Intel Fast CPU with SSE2. GPU with Pixel Shader 2.0 or greater. Some integrated graphics chips work but it depends on the model (and only with DirectX 9). I'm trying to make a light-weight quiet little machine for streaming video and playing eumulators, and I'm trying to figure out the minimum requirements I will need to do what I want. I know I'm not supposed to ask for product recommendations here, so if you could just advise the minimum requirements in terms of CPU, graphics card, and RAM, that'd be helpful.

  • Need Help on entity framework

    - by Sarathi1904
    I have 3 tables(Roles,Actions and RoleActionLinks). Roles table has few columns(RoleID,RoleName,Desc). Actions table has few colums(ActionID,ActionName,Desc). In RoleActionLink is created for store the association between Roles and Actions and this table has the columns such as RoleID,ActionID When I created the data model(edmx). it shows only Role and Action as entity. i did not find RoleActionLink table. but even there is no direct relation between Roles and Actions table, both tables are automatically related using RoleActionLink table. When i create the new Action, a action record should be populated in Action table(this is works fine). At the same time, i need to populate record in RoleActionLinks table. But i dont have the entity to populate. Please tell me how to accomplish my needs.

  • How to convert a MKV video to a less CPU intensive video format?

    - by marco.ragogna
    I have a couple of videos at 1920x800 that use the MKV format (4.7 GB). A friend of mine has an old PC that has some problems playing them; the CPU is working at nearly 100%. Is it possible to convert these videos to a less CPU intensive video format? The final size is not a problem, it can also double or more. Into which format should I convert it and which software for Windows should I use (better if free)? Thank you in advance.

  • RSync to WebDAV mounted volume very slow

    - by AlexC
    I have a mounted WebDAV store, which I am playing around with to try and put together my own pseudo-DropBox set up. However, it seems very slow to upload larger files (my bandwidth graph goes ok for a little bit, then just stops dead for long periods of time). Has anyone tried this? I'm wondering if the way it gets mounted makes rsync think it's a local drive or something and so may be chattier than it would be if it knew it was a mounted network drive? (I'm new to rsync so may be all wrong here!) I'm syncing using rsync -rv /source/directory/ /mounted/webdav/directory/ This is running using MacOS 10.6, and WebDAV is mounted using the native mounting mechanism.

  • Office jukebox systems

    - by jonayoung
    We're looking for a good office jukebox solution where staff can select songs via a web interface to be played over the central set of speakers. Must haves: Web Interface RSS / easy to scrap display of currently playing songs Ability to play mp3s and manage an ordered playlist. Good cataloguing of media. Multiple OSs supported as clients - Windows, Mac, Fedora Linux (will probably be accomplished by virtue of a web interface). We have tried XBMC which worked well as a proof of concept however the web interface is just too immature and has too many bugs for a reliable multi-user solution. I believe the same will be true of boxee. Nice to have: Ability to play music videos onto a monitor Ability to listen to radio streams specifically Shoutcast and the BBC. Ability to run on Linux is a nice to have but windows solutions which worked well would certainly be considered. I am aware of question 61404 and don't believe this to be a duplicate due to the specific requirements.

  • Best way to upscale a video?

    - by Josh
    If I have a video file at 320x240 resolution which I want to re-encode (because I don't like the encoding it's in now) and I also want to play it at double size (640x480), will I get higher quality if I scale it up to 640x480 when I convert it to a new format, verses keeping it at 320x240 in the new format and playing it at double size? This probably depends on the program used to convert, and if so, please let me know any program which might increase the quality. Here's my thinking. If I play a 320x240 file at double size, the system has to scale up each frame in real time, whereas if I scale up while recompressing the system may be able to use a more intensive algorythm like Bicubic interpolation . However I am not sure if this is true or not.

  • Hibernate a user account when switching to different account in Windows 7 Home Premium (64bit)

    - by Sukotto
    Is there any way to have Windows 7 hibernate Bob's account when switched to Mary's account and vice versa? I.e.: Bob is logged in Bob clicks Start shutdown switch user Bob's session is saved to disk Mary logs in Mary's session is restored as it was when Bob's turn started Both are heavy users (30+ chrome tabs open, multiple documents, multiple spreadsheets, music playing, etc) I would like to set up the system so that each gets the full use of the computer while still having all their open apps the way they left them. I suppose I could try setting up a VM for each, but I'd rather not add anything else to the mix here if I don't have to. This is Windows 7 Home Premium 64-bit running on a Lenovo G550 laptop

  • Alsa hardware volume with PulseAudio

    - by Jan Hudec
    Before installing pulseaudio, I was able to control volume for the front (meaning on the front panel, the "headphone" jack) and rear (meaning on the back panel, the "line out" jack) separately. When I installed pulseaudio, it became possible to control volume for each playing process separately, but the individual controls for outputs disappeared. While the default device in alsa now routes via pulseaudio, the sysdefault device provides access to the hardware. But kmix does not seem to let me show them now. Is there any way to beat kmix into showing the sysdefault device too? Or something else X-based that would not fight with kmix too much? The system is Debian Jessie (testing) amd64, updated, KDE version 4:4.13.3-1.

  • Bind "media" keys on MacBook keyboard to application menu items

    - by Austin
    Currently, I am using PandoraBoy to listen to my Pandora stations. In the preferences, it allows you to set global hotkeys to control playing, like/dislike, volume, stations, etc. What I would like to do is allow the built-in media keys on my MacBook Pro's keyboard (F7-F12: Previous, Play/Pause, Next, Mute, Volume Up, Volume Down) to control PandoraBoy like they do iTunes. Right now, I am using Command-F(7-12) to control it, but that requires me to hold down the "fn" and command keys Is there a way to bind these commands to the media keys without needing to function-shift them?

  • Implementing a Suspension or Penalty System for Users in ASP.NET MVC

    - by Maxim Z.
    I'm writing a site in ASP.NET MVC that will have user accounts. As the site will be oriented towards discussion, I think I need a system for admins to be able to moderate users, just like we have here, on Stack Overflow. I'd like to be able to put a user into a "suspension", so that they are able to log in to the site (at which point they are greeted with a message, such as, "Your account has been suspended until [DATE]"), but are unable to do the functions that users they would normally be able to do. What's the best way of implementing this? I was thinking of creating a "Suspended" role, but the thing is, I have a few different roles for normal users themselves, with different privileges. Have you ever designed a feature like this before? How should I do it? Thanks in advance.

  • Run a program in compatibility mode without Administrator privileges

    - by a_m0d
    I have a PC which is mostly used for playing games. The PC is a few years old, running XP, and most likely won't ever be upgraded to Windows 7. However, there are a few games that need to be run in compatibility mode for some reason, and this currently requires them to be run as the administrator. Unfortunately, I haven't found any way around this - although I have the administrator password, I don't want to reveal it to the others who use the PC, and this means that I have to be present every time to start the program for them (using Run as ... - Administrator). Is there any way I can allow these programs to be run in compatibility mode without requiring elevated user privileges? I have already made the standard user a Power User, but this hasn't helped at all. Any advice would be appreciated.

  • I got these strange messages on my websites feedback form? Is someone trying to hack my site?

    - by Ali
    Hi guys - I got all of a sudden a number of strange feedback messages from my sites feedback form its where normally users would come and enter feedback and then I would review it on an admin panel. However these messages make little to no sense like for an example: here are two 'messages': 2GyOim <a href=\"http://vdjzpnoyzfji.com/\">vdjzpnoyzfji</a>, [url=http://gixlpbtswcdh.com/]gixlpbtswcdh[/url], [link=http://zudauexgjgot.com/]zudauexgjgot[/link], http://vqhafprwogyf.com/ jF2wdU <a href=\"http://aprjkscbhnxf.com/\">aprjkscbhnxf</a>, [url=http://dhfeoqufoqvu.com/]dhfeoqufoqvu[/url], [link=http://whmzpbqrsume.com/]whmzpbqrsume[/link], http://xxfntqzhhbza.com/ I got about over a dozen of these - and they are all from very different ips is someone playing around and is it a cause for me to get vigilant? Also they all have the exact same time and date of entry which is spooky?

  • Hard link not works under MacOS in GUI mode

    - by AntonAL
    Hi, i faced a little strange behavior, while using hard links. From terminal, i create a text file 1.txt and a hard link "to this file" nano 1.txt mkdir dir ln 1.txt ./dir/ I check the resulting hard link and see that its contents are the same as of the original file. less ./dir/1.txt I change the initial file ... nano 1.txt ... and see, that changes was reflected in hard-link less ./dir/1.txt I change content of hard-link (more correct, of course - file, being referenced with hard-link) ... nano ./dir/1.txt ... and see, that changes are reflected in initial file less 1.txt Until now, all going well... Now, I close terminal and start playing with created files (1.txt and ./dir/1.txt) from Finder. When i change on this two files with TextEdit, changes are not reflected in another file. Just like the hard link was teared off... What is going on here ?

  • What program is making this sound and how can I make it stop

    - by DrFredEdison
    Some program is intermittently making this weird "chook ... chick" sound, no more than every 5 minutes, but sometimes hours or days between making it. There seems to be no pattern as to when it happens, but the sound is definitely coming from the speakers, and is always the same, so I'm pretty confident some piece of software I'm running is playing the sound. Today, I managed to record it, and I've posted it here: http://tristanhavelick.com/chook-chick.mp3 Short of closing my programs one by one, and seeing if the sound continues, are there any tricks for tracking down a problem like this? Is there any software that can trace what sounds come from what programs (something like tcpview with waveforms)? I am running windows xp.

  • Make MySQL database replication always use the most free node?

    - by Chad Johnson
    We started using Multi-Master Replication Manager for MySQL, and I am wondering whether it is possible to to treat this setup like multi-symmetric processing: a process pops off the process queue, and the node (in this case a server) that is most free is selected for the job. It seems that what happens is, the service switches to a slave ONLY when it mysqld crashes or goes away. Is there a way to make database replication for MySQL act in more of a distributed manner? Maybe there is other software besides MMM that can do this? Is there a way to switch the reader role to another server whene mysqld slows down (rather than just when it fails)?

  • Setup Windows Media Player 11 to stream from TVersity

    - by snorfys
    I've got TVersity installed on a Windows 2003 server box (work had an extra license that they donated to let me install at home to get some practice setting up/administering a domain etc.) I found out that Windows Media Player 11 won't install on Windows 2003, but installed TVersity instead and streaming to my 360 is working great. Problem is that I don't know how to setup streaming to any other PC on the network. All of the PCs have access to the shared network folder, but playing from there doesn't stream and the stutter is pretty bad. Is there a way to setup Windows Media Player 11 or another player to stream from TVersity?

  • Wrong Sound Blaster's PCI ID within Windows

    - by pavian
    I own Sound Blaster X-Fi Titanium, it was working with no problems under Linux or Windows 7. It's original PCI ID is 1102:000b but now I see different within MS Windows. BIOS setup: 1102:000b GNU/Linux: 1102:000b Windows 7: 1102:000d Windows 8: 1102:000d In last days I'm experimenting with IOMMU PCI passthrough in Xen and I tried to pass this device to virtual Windows 7 and 8. Here I found this problem. I don't know if this is just coincidence or reason of my problem but it's wrong even in physical system. Windows detects 1102:000d as a High Definition Audio sound device (I guess this name, I have localized Windows, but this is general name, the same was with Realtek HDA before drivers), it's playing but it's unstable (Windows speaker testing can crash that application) and I can't install Creative software. Used driver is hdaudio.sys. Booting in BIOS or UEFI mode doesn't change anything. Nor CMOS clean. Someone met the same problem.

  • Prevent audio recording applications from picking up non-microphone audio output

    - by hheimbuerger
    When talking to people over Mumble/Teamspeak/Ventrilo, I have a few who are broadcasting all of their audio output (e.g. music playing in the background, game sounds, etc.) whenever they are sending -- in addition to the microphone signal. I don't have this problem myself, so it's hard for me to troubleshoot remotely, but I'm interested in collecting solutions for this problem for Windows XP, Vista and 7, so that I can link them to this question. Links to other related SU questions are highly welcome as well, but I couldn't find any. Most people seem to try to either get microphone to feed back into the audio output or turn exactly that off, which is different from this problem. I'm talking about the opposite problem, the output being fed into the input.

  • Keyboard doesn't let me press certain keys at the same time

    - by kitchen
    I'm not sure how to word the problem other than I can't use certain keys at the same time. For example, when playing games that require you to use the arrow keys to move and jump/duck I am unable to move to the left and jump (left arrow + up arrow) at the same time. As a result, I don't play many games when I get to a point where the jumps and what not are too far. This happens with other keys as well. In FPS I am unable to hold W to move forward and hit 2 to select my secondary weapon. Some information that might help you: I am using Windows 7 64-bit I am using a Micro Innovations KB565BL keyboard How can I fix this?

  • ASP.NET MVC authorization & permission to use model classes

    - by Tomek
    Hi, This is my first post here, so hello :) Okey, let's get to the point... I am writing my first app in ASP.NET MVC Framework and i have a problem with checking privileges to use instances of model classes (read, edit). Sample code looks like this: // Controller action [CustomAuthorize(Roles="Editor, Admin")] public ActionResult Stats(int id) { User user = userRepository.GetUser(id); if (user == null || !user.Activated || user.Removed) return View("NotFound"); else if (!user.IsCurrentSessionUserOwned) return View("NotAuthorized"); return View(user); } So far authorize attribute protects only controller actions, so my question is: how to make (custom) authorize attribute to check not only user role, usernames but also did i.e. resources instantiated in action methods (above: User class, but there are other ORM objects like News, Photos etc.) All of these object to check have their unique ID's, so user have own ID, News have their ID and UserID field referecned to Users table (i mean these objects are LINQ2SQL classes). How should i resolve that problem?
