• Active Directory password update not recognized on OS X 10.7.3?

  - by eaj

  We have a few Macs in our office which are bound to our Active Directory (Server 2k8R2) domain for login authentication and access to file shares. For the most part this has worked without trouble. I recently changed my AD password (from the Windows box that is my main desktop machine), and my iMac still wants my old password for logins—even after a reboot. It correctly prompts for the new password when I attempt to connect to Windows smb file shares. The last time I changed my password, the iMac was running Snow Leopard and picked up the password change as expected. I'm a little bit of an OS X n00b, so I apologize if this should be obvious. My searching has turned up numerous issues people have had with Lion and Active Directory, but not this particular problem. Possibly related, we do have mobile accounts enabled for AD in the Directory Utility options. I assume this causes credentials to be cached locally, but it's not clear to me how to get them to update.

• grep only returns help text

  - by Pete Mancini

  Well, I am perplexed. I am working with an Ubuntu server and I type in grep 'bash' *.sh BUT fgrep 'bash' *.sh works like a champ. which grep and which fgrep both point to their respective executables in /bin. I am perplexed as to what I am doing wrong. EXAMPLE output: $ grep -F 'grounding' repl.clj Usage: grep [OPTION]... PATTERN [FILE]... Search for PATTERN in each FILE or standard input. PATTERN is, by default, a basic regular expression (BRE). Example: grep -i 'hello world' menu.h main.c $ fgrep 'grounding' repl.clj (p/concepts-for-grounding-term imp1 "PERSON" "summary") See? grep is failing but fgrep is working fine. That is why I am perplexed.

• How can I know if a VM is used or not?

  - by Saariko

  I am running eSXI 4.1. In my main datastore I have plenty of folders, some of them has logical names, while the others don't, they hold BASE configurations/images of clients that I duplicate and activate. I only have a fraction of the actual clients loaded and running on the server. How can I know, but looking in the datastore folder, if the VM is in the inventory or not? If I right click on the vmx file, I can add it to the inventory - EVEN if the same client/folder is already active.

• solving network connection problem on xp

  - by doug

  Hi there I feel so stupid, because I have to fix my dad computer(which was mine years ago). So it is an old computer on which I have installed windows xp and the drivers for main-board. The device manager says that I have no more problems with the hardware. That computer has to connect to a router from my room but it doesn't. On ping 192.168.2.1 I get "Request time out"., The other computers are connecting to that router. Only the old computer doesn't connect to the LAN and later to the internet. Also it doesn't get a good IP(from the same class). After running ipconfig command I know that i have an IP with 169.... What can I do? Do you have any tips for me?

• Is it reasonable to require passwords when users sign into my application through social media accounts?

  - by BrMcMullin

  I've built an application that requires users to authenticate with one or more social media accounts from either Facebook, Twitter, or LinkedIn. Edit Once the user has signed in, an 'identity' for them is maintained in the system, to which all content they create is associated. A user can associate one account from each of the supported providers with this identity. I'm concerned about how to protect potential users from connecting the wrong account to their identity in our application. /Edit There are two main scenarios that could happen: User has multiple accounts on one of the three providers, and is not logged into the one s/he desires. User comes to a public or shared computer, in which the previous user left themselves logged into one of the three providers. While I haven't encountered many examples of this myself, I'm considering requiring users to password authenticate with Facebook, Twitter, and LinkedIn whenever they are signing into our application. Is that a reasonable approach, or are there reasons why many other sites and applications don't challenge users to provide a user name and password when authorizing applications to access their social media accounts? Thanks in advance! Edit A clarification, I'm not intending to store anyone's user name and password. Rather, when a user clicks the button to sign in, with Facebook as an example, I'm considering showing an "Is this you?" type window. The idea is that a user would respond to the challenge by either signing into Facebook on the account fetched from the oauth hash, or would sign into the correct account and the oauth callback would run with the new oauth hash data.

• Is there a software that can remap the keys for a speficic keyboard?

  - by Vilx-

  There are several keyboards attached to my computer. I'd like to remap the keys on ONE of them, but keep the rest as they were. Is there a software that does this? As for the "why" - I have this idea that I'd like to have a "multimedia keypad" which is separate from my main keyboard, but I could not find any online. So I think that I could take a typical USB numpad (they cost like 5$), and remap the keys on one of them. Add appropriate stickers, and I'm all seat, cheaply. I know that it's theoretically possible, but before I get my hands dirty and write my own software, I'd like to see if there's maybe an existing one out there. Oh, yes, I'm running Windows 7.

• Problems bringing up a second virtual network interface

  - by tubaguy50035

  I'm having issues adding a second IP address to one interface. Below is my /etc/networking/interfaces # The loopback network interface auto lo iface lo inet loopback #eth0 is our main IP address auto eth0 iface eth0 inet static address 198.58.103.* netmask 255.255.255.0 gateway 198.58.103.1 #eth0:0 is our private address auto eth0:0 iface eth0:0 inet static address 192.168.129.134 netmask 255.255.128.0 #eth0:1 is for www.site.com auto eth0:1 iface eth0:1 inet static address 198.58.104.* netmask 255.255.255.0 gateway 198.58.104.1 When I run /etc/init.d/networking restart, I get a fail error about bringing up eth0:1: RTNETLINK answers: File exists Failed to bring up eth0:1. Any reason this would be? I didn't have any problems with I first set up eth0 and eth0:0.

• Simple server status page hosted externally available for users

  - by Chris

  I am looking for any kind of script - can be asp or php or any other web language - that gives me the ability to log outages and the current state of the network for our organisation. This would be similar to any major Telco's "Network Status" page, but I just want to tell the user's out there if the systems are up and running and have a history of recent outages. This would be for our remote user's so they could go to a webpage (externally hosted from our main site) and see that we are currently having problems with our network. What are other people out there using?

• How can I stop ntbackup requiring my new password every time I'm forced to change my Windows passwor

  - by Lunatik

  I have a scheduled job that runs each night using ntbackup which copies a folder on my HDD to a network share. The problem is that every time I'm required to change my Windows password I have to remember to change it in ntbackup aswell, otherwise the backup fails silently i.e. I get no warning that the backup isn't being done. Is there a way to schedule this job so it will automatically pick up my new Windows password, or somehow not be tied to my main login? My user account type is Debugger, not full Administrator, so I'm not sure if that would restrict me in any way, e.g. still forcing a four-weekly password change on a dedicated user account for this. The PC runs XP SP2 on a Windows Server 2003 R2 domain.

• How to implement Restricted access to application features

  - by DroidUser

  I'm currently developing a web application, that provides some 'service' to the user. The user will have to select a 'plan' according to which she/he will be allowed to perform application specific actions but up to a limit defined by the plan. A Plan will also limit access to certain features, which will not be available at all for some plans. As an example : say there are 3 plans, 2 actions throughout the application users in plan-1 can perform action-1 3 times, and they can't perform action-2 at all users in plan-2 can perform action-1 10 times, action-2 5 times users in plan-3 can perform action-1 20 times, action-2 10 times So i'm looking for the best way to get this done, and my main concerns besides implementing it, are the following(in no particular order) maintainability/changeability : the number of plans, and type of features/actions will change in the final product industry standard/best practice : for future readiness!! efficiency : ofcourse, i want fast code!! I have never done anything like this before, so i have no clue about how do i go about implementing these functionalities. Any tips/guides/patterns/resources/examples? I did read a little about ACL, RBAC, are they the patterns that i need to follow? Really any sort of feedback will help.

• How to reset the language of the package descriptions

  - by xubuntix

  I have had German as my main language about a year ago. Later I changed it to English. Most parts of the system accepted the change. The notable exceptions are the package descriptions, which remain in German for some packages. You can see in the image (apt-cache and software-center), that while some descriptions are in English, some have remained in German. So the question is: how do I reset this? I guess that there is somewhere a description cache that needs to be told that it should update all descriptions? EDIT: As asked: the output of some language related commands: $ cat /etc/default/locale LANG="en_US.UTF-8" $ apt-config dump | grep Lang Acquire::Languages ""; Acquire::Languages:: "de_DE"; Acquire::Languages:: "de"; Acquire::Languages:: "en"; Acquire::Languages:: "none"; $ locale LANG=de_DE.UTF-8 LANGUAGE=en LC_CTYPE="de_DE.UTF-8" LC_NUMERIC="de_DE.UTF-8" LC_TIME="de_DE.UTF-8" LC_COLLATE="de_DE.UTF-8" LC_MONETARY="de_DE.UTF-8" LC_MESSAGES="de_DE.UTF-8" LC_PAPER="de_DE.UTF-8" LC_NAME="de_DE.UTF-8" LC_ADDRESS="de_DE.UTF-8" LC_TELEPHONE="de_DE.UTF-8" LC_MEASUREMENT="de_DE.UTF-8" LC_IDENTIFICATION="de_DE.UTF-8" LC_ALL= As a note: I'm not sure what each entry means, but some of the de_DE.UTF-8 are probably ok, since I do want paper-sizes, monetary, time, etc. in standard German formats.

• List has no value after adding values in

  - by Sigh-AniDe

  I am creating a a ghost sprite that will mimic the main sprite after 10 seconds of the game. I am storing the users movements in a List<string> and i am using a foreach loop to run the movements. The problem is when i run through the game by adding breakpoints the movements are being added to the List<string> but when the foreach runs it shows that the list has nothing in it. Why does it do that? How can i fix it? this is what i have: public List<string> ghostMovements = new List<string>(); public void UpdateGhost(float scalingFactor, int[,] map) { // At this foreach, ghostMovements has nothing in it foreach (string s in ghostMovements) { // current position of the ghost on the tiles int mapX = (int)(ghostPostition.X / scalingFactor); int mapY = (int)(ghostPostition.Y / scalingFactor); if (s == "left") { switch (ghostDirection) { case ghostFacingUp: angle = 1.6f; ghostDirection = ghostFacingRight; Program.form.direction = ""; break; case ghostFacingRight: angle = 3.15f; ghostDirection = ghostFacingDown; Program.form.direction = ""; break; case ghostFacingDown: angle = -1.6f; ghostDirection = ghostFacingLeft; Program.form.direction = ""; break; case ghostFacingLeft: angle = 0.0f; ghostDirection = ghostFacingUp; Program.form.direction = ""; break; } } } } // The movement is captured here and added to the list public void captureMovement() { ghostMovements.Add(Program.form.direction); }

• Java and C# in web development [on hold]

  - by azalut

  I am wondering whether C# development(ASP.NET) is rather kind of "rapid development" or something "big" like JavaEE/Spring? We all know, that RoR or Django are really rapid-development frameworks - and so - is C# closer to Java "long-timed-development" or to frameworks like the two above - Django, RoR? I am, for now, an amateur Java programmer and sometimes I get annoyed with the amount of code that have to be written to create even a short CRUD app. We need a lot of skills to create at least a small app. I want some change, at least for some time and learn something new. I tried (just few hours) first: RoR, then Django and now I am writing in C#. It seems to be like Java but a little bit extended. In respect of future work as a professional coder - Is it profitable to know both competitive technologies like Java (and its frameworks) and C# with .NET(ASP.NET for example)? Maybe better choice is Python? Or just stop being stupid and still work with Java but with another framework(and master my Java skills) or JavaScript, jQuery to be better at web-development? Actually this question depends on your own opinions that is why I know that this question could be blocked by admins. But main question is in the top of the post I mean: is C# web-development rapid or closer to Java? I am afraid, that if I don't try, I will regret in the future, when I awake and think: oh my god, how could I not get familiar with (another_technology_or_language) Thanks for your attention :) ps I had asked the same question on stackoverflow, but it was hold because of being opinion based. Hope it fits here ;)

• If I want to dual-boot Ubuntu with another OS, what partitioning method should I use?

  - by Jay

  I have Ubuntu running as a vm in VirtualBox at the moment, but in the future, if I want to dual-boot it with Windows or another OS installed on my hard-drive, what partitioning method should I use to make room for it? 1)Manually partition my hard drive via disk management in Windows (or the equivalent in another OS), making appropriate room for the main partition upon which Ubuntu will be installed and swap space; 2)Partition via the Ubuntu installer options; 3)Use gparted or another free tool like it. I am uncertain as to why I would want to use one over the other. Lastly, am I correct to think that it would be the acme of foolishness to try to partition drives within a virtual machine (since that partitioning would be inherently limited to the limitations set upon it by the virtualization software, e.g., VirtualBox)? Thanks! P.S. Oh, and I am also planning on not modifying the MBR of Windows if I ever do dual-boot with Ubuntu, using instead a piece of free software (like easyBCD or something) to avoid the headaches of Grub being overwritten by a Windows update.

• Call DB Stored Procedure using @NamedStoredProcedureQuery Injection

  - by anwilson

  Oracle Database Stored Procedure can be called from EJB business layer to perform complex DB specific operations. This approach will avoid overhead from frequent network hits which could impact end-user result. DB Stored Procedure can be invoked from EJB Session Bean business logic using org.eclipse.persistence.queries.StoredProcedureCall API. Using this approach requires more coding to handle the Session and Arguments of the Stored Procedure, thereby increasing effort on maintenance. EJB 3.0 introduces @NamedStoredProcedureQuery Injection to call Database Stored Procedure as NamedQueries. This blog will take you through the steps to call Oracle Database Stored Procedure using @NamedStoredProcedureQuery.EMP_SAL_INCREMENT procedure available in HR schema will be used in this sample.Create Entity from EMPLOYEES table.Add @NamedStoredProcedureQuery above @NamedQueries to Employees.java with definition as given below - @NamedStoredProcedureQuery(name="Employees.increaseEmpSal", procedureName = "EMP_SAL_INCREMENT", resultClass=void.class, resultSetMapping = "", returnsResultSet = false, parameters = { @StoredProcedureParameter(name = "EMP_ID", queryParameter = "EMPID"), @StoredProcedureParameter(name = "SAL_INCR", queryParameter = "SALINCR")} ) Observe how Stored Procedure's arguments are handled easily in  @NamedStoredProcedureQuery using @StoredProcedureParameter.Expose Entity Bean by creating a Session Facade.Business method need to be added to Session Bean to access the Stored Procedure exposed as NamedQuery. public void salaryRaise(Long empId, Long salIncrease) throws Exception { try{ Query query = em.createNamedQuery("Employees.increaseEmpSal"); query.setParameter("EMPID", empId); query.setParameter("SALINCR", salIncrease); query.executeUpdate(); } catch(Exception ex){ throw ex; } } Expose business method through Session Bean Remote Interface. void salaryRaise(Long empId, Long salIncrease) throws Exception; Session Bean Client is required to invoke the method exposed through remote interface.Call exposed method in Session Bean Client main method. final Context context = getInitialContext(); SessionEJB sessionEJB = (SessionEJB)context.lookup("Your-JNDI-lookup"); sessionEJB.salaryRaise(new Long(200), new Long(1000)); Deploy Session BeanRun Session Bean Client.Salary of Employee with Id 200 will be increased by 1000.

• WINAPI beginner guidance question

  - by gekod

  I'm learning to develop windows applications using WINAPI and plain C. Now I got a bit confused with all those handles and would like to ask if you guys could teach me some good practices to structure and handle controls and windows. Here's where I get confused: Using the IDs declared in the resources for each object, we can get their handles using GetDlgItem(). Now what if we don't know their parent, which is needed by this function. One example: We have the main window created at launch. Then we register two new window classes and create a window for each new class and we create a message function for each too. Now if inside one of the children windows I create a button and inside the other child window I create a text label. Now when we click the button inside of child window A the label in child window B shall be modified to whatever. The WM_COMMAND for the button is interpreted inside the message loop for child window A. Now what would be the best and more elegant way to access the text label inside the child window B? I am in the process of learning the WINAPI and just want to learn it right from the start instead of producing Hacked code that someday becomes unreadable and to later have to adapt to a new way of programing.

• Creating deterministic key pairs in javascript for use in encrypting/decrypting/signing messages

  - by SlickTheNick

  So I have been searching everywhere and havn't been able to find anything with the sufficient information I need.. so Im a bit stumped on this one at the moment What I am trying to do is create a public/private key pair (like PGP) upon a users account creation, based on their passphrase and a random seed. The public key would be saved on the server, and ideally the private key would never be seen by the server whatsoever. The user could then sign in, and send a message to another user. Before the message is sent, the senders key pair would be re-generated on the fly based on their credentials (and maybe a password prompt) and used to encrypt the message. The receiver would then use their own re-generated private key to decrypt said message. The server itself should never see any plaintext passwords, private keys or readable messages. Bit unsure how on how I could go about implementing this. Iv been looking into PGP, specifically openPGP.js. The main trouble I am having is being able to regenerate the key-pair based off a specific seed. PGP seems to have a random output even if the inputs are the same. Storing the private key in a cookie or in HTML5 storage or something also isnt really an option, too unreliable. Can anyone point me in the right direction?

• Is it safe to operate a laptop without battery?

  - by leladax

  I know it's 'unsafe' in terms of data loss but I noticed motherboards still have some of their circuits on power when they are plugged in [e.g. a circuit that must wait for power-on signals is certainly one of them]. Hence, I wondered if it would increase the life of the laptop if the battery was simply off. Let alone that may also increase battery life, but that's the least of my concerns. Notice the main point is to plug it off on hibernate and have no power source whatsoever for the duration of being off (apart from the clock battery). (i.e. saving having to plug off the battery every time)

• Should I use subdomains or subfolders for my user groups?

  - by bilygates

  Hello, I run a photography website where each user has its own subdomain (i.e. user.site.com). I'm thinking of adding user groups but I'm unable to decide if I should also associate a separate subdomain or simply a subfolder for each group: Subfolders (www.site.com/groups/my-group) Pros: Easier to maintain from a tehnical p.o.v. Cons: Harder to memorize. The URLs can get really long (www.site.com/groups/my-group/albums/my-album/) Subdomains (my-group.site.com) Pros: Easier to memorize. Shorter URLs. One might have the impression that such an URL is somewhat more "independent" from the main site. Cons: Group and user names belong to the same name space, so we need to check for collisions when creating a new user/group. One cannot determine the content of the page by only reading the URL: Is x.site.com a user page or a group page? What's your opinion on the matter? I should note that DeviantArt.com uses the 2nd option (that's where I got the idea). Thank you in advance!

• OpenXDK Questions

  - by iamcreasy

  I was strolling around XBox development. Apart form buying a DevKit from Microsoft, another thing got my attention is called, OpenXDK which stands for Open XBox Development Kit. From their main site its pretty obvious that there hasn't been any update since 2005 but digging a little deeper, I found that in their project repository is was being updated. Last time stamp was 2009-02-15. Quick google search said, its not actually really on a good place to poke around. Many and MANY features are absent. Being a hobby project I perfectly understand. But, those results are quite old. The question is, is there anybody who has any experience with OpenXDK? If is, that is it possible to shade some light on this? about its limitations? Is this a mature project? How's the latest version and what's it capable of doing? Or should I just stay away from it?

• Is anyone else having issues with opening app links on iOS6 iPad3?

  - by lindon fox

  Links to ios apps (to the app store) are not working for me on my iPad 3/iOS 6. I thought it was my code causing the problem initially, but then I tried it on an iPhone, and an older iPad 2 and they both worked. I looked into it further and it seems no links are working (that I can find). I have googled, but I have not found anything yet. Is there anyone else having this problem? Example: link - this link will work on my computer and phone, but not on my iPad3 running iOS6 - it will just bring up the app store app showing the main screen.

• Keyboard shortcut / navigation references

  - by jerryjvl

  I use the mouse much too freely, and my wrists are not thanking me for it. I have been meaning to try and use the keyboard more as my sole means of navigating Windows, but I am having trouble sticking with it because when I need to do something and I cannot find the right shortcut, I grab the mouse and forget to let go of it again. Personally, the main software that I need keyboard reference sheets for would be: Firefox Thunderbird Visual Studio Windows itself But I would encourage more general inclusion of shortcut references in the answers in case anyone else tries to make the same transition I am attempting ;) What I am looking for is reference material that is as comprehensive as possible so that over time I can hopefully learn to do everything with the keyboard and spare my wrists. Bonus points for references that can be printed in a reasonable size so I can keep them next to my machine in hardcopy. I know there is an answer for Windows already: Is there a definitive reference for Windows shortcuts keys?, but I am leaving it in my question in case anyone has a better printable alternative.

• nginx caching per user agent

  - by Tuinslak

  I'm currently using nginx as reverse proxy with caching enabled. However, the main site has two different layouts, depending on the user-agent (mobile or not). I've tried something similar to this: # mobile users if ($http_user_agent ~* '(iPhone|iPod|mobile|Android|2.0\ MMP|240x320|AvantGo|BlackBerry|Blazer|Cellphone|Danger|DoCoMo|Elaine/3.0|EudoraWeb|hiptop|IEMobile)') { set $iphone_request '1'; } if ($iphone_request = '1') { proxy_cache mobile; } if ($iphone_request = '') { proxy_cache site; } proxy_cache_key "$scheme://$host$request_uri"; proxy_pass http://real-site.tld; However, nginx gives an error, stating proxy_cache can't be used in an if-structure. Any other way to serve from a different cache depending on the browser? Thanks, Tuinslak

• Hello!

  - by barryoreilly

  After many months of deliberating I have finally gotten around to starting this blog! The reason for doing this is the large number of half finished articles lying around on my hard disk, unpublished and unloved. These articles have been of huge benefit to me, and have been written in an attempt to consolidate my own thinking, in order to help me structure my thoughts and ideas as I have tried to digest new ideas and understand abstract theories. It is my hope that by tidying up these articles and publishing them here that I can continue this learning process by getting feedback on the ideas from within the developer community. i have worked with .NET for 8 years now, and have worked with ASP.NET, SQL Server, Windows programming as well as general network administration. Since 2004 my focus has been on integration, web services, and more often than not Biztalk Server. The last two years have seen me focus on SOA and WCF, and the Managed Services Engine, so this is probably where the main focus of the blog will to start with, but there are so many fun things to play with these days that i have no idea where it will end up.....   Barry
