• SQL Server Management Studio Connect to Server List Editing

  - by Paul Farry

  I'm using SQLServer Management Studio (2005) and I have a fairly lengthy list of servers in there, and I'd like to get rid of some of them that are no longer in use, without having to set them all up again. I know that the C:\Users\*\AppData\Roaming\Microsoft\Microsoft SQL Server\90\Tools\Shell\mru.dat can be deleted and this will remove ALL the entries, but is there anyway to just delete some of them? (Coding info) I looked at the file and it is a serialised blob from the Microsoft.SqlServer.Express.ConnectionDlg.dll (Class Personalization) in the Appplication directory, but all the methods are private. So I can't just create an instance of this and then call Remove on the entries. Update I have written an Article on CodeProject explaining How this can be achieved. http://www.codeproject.com/KB/vb/AlterSQL2005MRU.aspx

• Setting up a SQL server outside the domain

  - by user12391

  Hi, im very new to this. I've set up an account "SQLBOX" thats on the a network, but not connected to the domain. I have installed an instance of SQL Server 2008 and am trying to connect to it from another machine on the network but am getting "Cannot connect to "SQLBOX"". From the "SQLBOX" i can connect to sqlservers on the domain, but not vice-versa. Any help would be greatly appreciated. Sorry if the description isn't great. EDIT I can ping the box from a machine on the domain

• How to collaborate on features using github

  - by Robert Dailey

  github encourages 1 fork per user, so that that user can work independently on a feature and then request that feature to be accepted into the main repository via pull request. However, what if 2 developers need to collaborate on that feature? What is the ideal workflow for this? I could see a number of options: Both developers fork the original repository. Each developer pulls/pushes changes between each other's repository. This seems like a lot of work (tiny micro operations) and also creates a delay between changes, so increases the window for conflicts. Developer 1 forks from the main repository, developer 2 forks from developer 1. Same as #1 mainly but hopefully simplifies Developer 2's life a little? Developer 1 gives Developer 2 permissions to his own fork, so they both work out of the same central repository. Not sure if this is ideal. I'm also curious where branches come into this. Obviously there would be a branch for the feature itself but that branch can't exist in a single place, it would have to exist on multiple forks and be synchronized. Basically just really confused about this workflow, would like an approach for how this can be best accomplished.

• Linux Centos - Mail Deamon Preferences

  - by Iestyn

  I keep getting emails from root into my inbox, I get about 30 a day which is annoying as hell and I'm wondering how I can filter these emails down so that I only receive the essential emails. I don't want to have an email every single time I log in via SSH, but when you 30-40 a day sometimes it can get pretty annoying. Is there a section in cPanel or WHM where I can tick or un-tick a section to choose which emails I wish to receive? I also get mail deamon bounce email messages which I'd also like to disable. I've looked and looked, but I think I'm either overlooking something simple or I'm looking in the wrong place.

• Bash: Created a ~ (Tilde) in a directory by accident

  - by user1500360

  I'm a beginner to using bash on OSX, and I somehow created a ~ dir in a project subfolder. (It appears as a directory, rather than a symlink.) Is there a safe way to get rid of this ~ directory instance without bash expanding the tilde wiping my local user directory? This is a really goofy question, but it would be a huge help to figure out how to deal with this. Solution: I ended up using rm -rfi ./\~, which worked safely. Thanks, everyone!

• Benefits of Server-side Coding

  There are numerous advantages to server scripting languages over client side languages in regards to creating web sites that are more compelling compared to a standard static site. Server side scripting are scripts that are executed on a web server during the compilation of data to return to a client. These scripts allow developers to modify the content that is being sent to the user prior to the return of the data to the user as well as store information about the user. In addition, server side scripts allow for a controllable environment in which they can be executed. This cannot be said for client side languages because the developer cannot control the users’ environment compared to a web server. Some users may turn off client scripts, some may be only allow limited access on the system and others may be able to gain full control of the environment.  I have been developing web applications for over 9 years, and I have used server side languages for most of the applications I have built.  Here is a list of common things I have developed with server side scripts. List of Common Generic Functionality Send Email FTP Files Security/ Access Control Encryption URL rewriting Data Access Data Creation I/O Access The one important feature server side languages will help me with on my website is Data Access because my component will be backed with a SQL server database. I believe that form validation is one instance where I might see server-side scripts and JavaScript used interchangeably because it does not matter how or where the data is validated as long as the data that gets inserted is valid. However, I would have to say that my personal experience would have to sway me in deciding what type of languages to use for form validation because they both have advantages and disadvantages based on the each situation.

• Installing Sharepoint 2007 on Windows Server 2008 R2

  - by ronischuetz

  we are using in our lab a clean installation of Windows Server 2008 R2 which is running as Hyper-V instance. Today we wanted to install a clean installation of Sharepoint 2007 with SP1 on this machine and we explorer an error that we are not able to install it. The setup is comes up with an error which is described here: http://support.microsoft.com/kb/962935 but this is not our szenario. A printscreen of this message can be found here: http://www.ronischuetz.com/images/SP_2007SP1_Inst_Error.png @Microsoft, my personal point of view is that it cannot be that we need to install first 2008, then Sharepoint 2007 with SP1, then SP2 and upgrade to 2008 R2. Nobody is going be happy with this solution and I hope we find a fast way how customers can install Sharepoint direclty on 2008 R2. Anyway, thanks in advance for any further information how we should go on with this issue. The issue is listed here: http://social.msdn.microsoft.com/Forums/en-US/sharepointadmin/thread/91a6be50-9009-43c8-a37c-66cfb83d738f

• How can I get ssh-agent working over ssh and in tmux (on OS X)?

  - by Rich

  I have a private key set up for my github account, the passphrase to which is, I believe, stored in OS X's keychain. I certainly don't have to type it in when I open a terminal window and enter ssh [email protected]. However, when I'm running bash over an ssh session, or locally inside a tmux session, I have to type in the passphrase every single time I attempt to ssh to github. This question suggests that a similar problem exists with screen, but I don't really understand the issue well enough to fix it in tmux. There's also this page which includes a fairly complicated solution, but for zsh. EDIT: In response to @Mikel's answer, from a local terminal I get the following output: [~] $ echo $SSH_AUTH_SOCK /tmp/launch-S4HBD6/Listeners [~] $ ssh-add -l 2048 [my key fingerprint] /Users/richie/.ssh/id_rsa (RSA) [~] $ typeset -p SSH_AUTH_SOCK declare -x SSH_AUTH_SOCK="/tmp/launch-S4HBD6/Listeners" Whereas over ssh or in tmux I get: [~] $ echo $SSH_AUTH_SOCK [~] $ ssh-add -l Could not open a connection to your authentication agent. [~] $ typeset -p SSH_AUTH_SOCK bash: typeset: SSH_AUTH_SOCK: not found echo $SSH_AGENT_PID returns nothing whatever shell I run it from.

• How to calculate bandwidth limits per user on WiFi network

  - by Lars

  A typical 802.11g access point can provide around 25 Mbps of bandwidth. How is the bandwidth shared among the users? Furthermore, how many users can be served by a single access point using 802.11g in an environment with low interference, and average web activity from the users? The goal is to use bandwidth limitation to avoid starvation for some users in case some of the users start to download a file or stream HD video or some other bandwidth intensive activity. Can someone break down the math on this?

• SOLR high CPU usage in amazon EC2

  - by user644745

  I installed solr-3.6 in my local windows box and it worked fine. I installed solr-4.0 in amazon ec2 linux large instance and the cpu usage shot upto 100%. It maintained at 80-90% average cpu power. I thought it could be because of 4.0, So I installed 3.6 in EC2 again. But again the CPU usage was 80-90% average. With both the versions, solr works in EC2. dont know why CPU usage is so high. i started the solr server using "sudo nohup java -jar start.jar &" In my local box java 1.7 is installed and in EC2 it is 1.6.0_24. I have mapped solr dir to an EBS volume. /dev/mapper/vg1-solr 8361916 1935928 6342128 24% /home/ec2-user/SOLR/solr/example/solr Is there any known issue ?

• Repeat use of Schema / Rich Snippets Markup i.e LocalBusiness Data

  - by bybe

  I am unable to find official wording and I'm hoping that some Rich Snippets/Schema Guru can give me some insight into proper usage of repeated content when it comes to using markup. I'm building a site that wants to use Schema as the markup type and the owner would like as much usage as possible. The business name, telephone and address will appear on every page now is it valid or even useful to use Rich Snippets on every page where this information is displayed. For example this information appears in the header, and footer of every page of the site and too give you an example of my current markup see below: <body itemscope itemtype="http://schema.org/LocalBusiness"> <header> <a itemprop="url" href="http://www.domain.co.uk/"> <img itemprop="logo" src="image.png" alt="Company Name Logo" /> </a> <span itemprop="telephone">01202 000 000</span> </header> <div> This is where the content will go</div> <footer> <span itemprop="name">Company Name</span> <span itemprop="description"> A small little bit about this company</span> <div itemprop="address" itemscope itemtype="http://schema.org/PostalAddress"> <span itemprop="streetAddress">Address Goes here</span> <span itemprop="addressLocality">Area Here</span>, <span itemprop="addressRegion">Region Here</span> </div> </footer> </body> !-- Local Business Schema Now Closed --> So as you can see above this information will be displayed on every single page.... Is this valid or bad to repeat usage of this information in schema format...

• Setting up Kerberos SSO in Windows 2008 network

  - by Arturs Licis

  We recently introduced Kerberos (SPNEGO) Single Sign-on in our web-portal, and tested it on a Windows network with Windows 2003 domain controller. Now, trying to test it on Windows 2008 R2 controlled network, SSO just doesn't work due to defective tokens. Up to the moment I was pretty sure that there's something wrong about environment and that were NTLM tokens. We double checked IE settings etc, but nothing helped. Then we checked the following settings for both users (logged on a client test-machine, and the one used as a Service Principal): This account supports Kerberos AES 128 bit encryption. This account supports Kerberos AES 256 bit encryption. .. and error message changed to ' GSSException: Failure unspecified at GSS-API level (Mechanism level: Encryption type AES256CTS mode with HMAC SHA1-96 is not supported/enabled) It makes me think that Internet Explorer receives Kerberos tokens at all times, and there's just some configuration missing, or it was ktpass.exe to be incorrectly executed. Here's how ktpass.exe was invoked: C:ktpass /out portal1.keytab /mapuser USER /princ HTTP/[email protected] /pass *

• Remote Debugging

  - by Pemdas

  Obviously, the easiest way to solve a bug is to be able to reproduce it in house. However, sometimes that is not practical. For starters, users are often not very good at providing you with useful information. Costumer Service: "what seems to be the issue?" User: "It crashed!" To further compound that, sometimes the bug only occurs under certain environmentally conditions that can not be adequately replicated in house. With that in mind, it is important to build some sort of diagnostic framework into your product. What type of solutions have you seen or used in your experience? Logging seems to be the predominate method, which makes sense. We have a fairly sophisticated logging frame work in place with different levels of verbosity and the ability to filter on specific modules (actually we can filter down to the granularity of a single file). Error logs are placed strategically to manufacture a pretty good representation of a stack trace when an error occurs. We don't have the luxury of 10 million terabytes of disk space since I work on embedded platforms, so we have two ways of getting them off the system: a serial port and a syslog server. However, an issue we run into sometimes is actually getting the user to turn the logs on. Our current framework often requires some user interaction.

• Canonical representation of a class object containing a list element in XML

  - by dendini

  I see that most implementations of JAX-RS represent a class object containing a list of elements as follows (assume a class House containing a list of People) <houses> <house> <person> <name>Adam</name> </person> <person> <name>Blake</name> </person> </house> <house> </house> </houses> The result above is obtained for instance from Jersey 2 JAX-RS implementation, notice Jersey creates a wrapper class "houses" around each house, however strangely it doesn't create a wrapper class around each person! I don't feel this is a correct mapping of a list, in other words I'd feel more confortable with something like this: <houses> <house> <persons> <person> <name>Adam</name> </person> <person> <name>Blake</name> </person> </persons> </house> <house> </house> </houses> Is there any document explaining how an object should be correctly mapped apart from any opninion?

• Can too much abstraction be bad?

  - by m3th0dman

  As programmers I feel that our goal is to provide good abstractions on the given domain model and business logic. But where should this abstraction stop? How to make the trade-off between abstraction and all it's benefits (flexibility, ease of changing etc.) and ease of understanding the code and all it's benefits. I believe I tend to write code overly abstracted and I don't know how good is it; I often tend to write it like it is some kind of a micro-framework, which consists of two parts: Micro-Modules which are hooked up in the micro-framework: these modules are easy to be understood, developed and maintained as single units. This code basically represents the code that actually does the functional stuff, described in requirements. Connecting code; now here I believe stands the problem. This code tends to be complicated because it is sometimes very abstracted and is hard to be understood at the beginning; this arises due to the fact that it is only pure abstraction, the base in reality and business logic being performed in the code presented 1; from this reason this code is not expected to be changed once tested. Is this a good approach at programming? That it, having changing code very fragmented in many modules and very easy to be understood and non-changing code very complex from the abstraction POV? Should all the code be uniformly complex (that is code 1 more complex and interlinked and code 2 more simple) so that anybody looking through it can understand it in a reasonable amount of time but change is expensive or the solution presented above is good, where "changing code" is very easy to be understood, debugged, changed and "linking code" is kind of difficult. Note: this is not about code readability! Both code at 1 and 2 is readable, but code at 2 comes with more complex abstractions while code 1 comes with simple abstractions.

• Tuning OpenVZ Containers to work better with Java?

  - by Daniel

  I have a 8 GB RAM Server (Dedicated) and currently have KVM Virtual Machines running on there (successfully) however i'm considering moving to OpenVZ as KVM seems a bit overkill with a lot of overhead for what i use it for. In the past i have used OpenVZ Containers, hosted by myself and from other providers and Java doesn't seem to work well with them.. One example is that if i give a container 2 GB RAM ( No burst) (with or without vswap doesn't matter) a java instance can only be tuned to use at very most 1500 MB of that RAM (-Xmx, -Xms). Ideally, i wish to be able to create "Mini" containers with about 256MB, 512MB, 768 RAM and run some java instances in them. My question is: I'm trying to find an ideal way to tune a OpenVZ container configuration to work better with Java memory. Please, don't suggest anything related to Java settings, i'm looking for OpenVZ specific answers.. Though i welcome any suggestion if you feel it may help me. Much Appreciated, Daniel

• Trying to find a recent - PHP book - that utilizes SOLID principles! [closed]

  - by darga33

  Pulling my hair out! I have heard of Martin Fowler's book PoEAA and the other book Head First OOA OOD but those are not in PHP. I desperately want to read them, but ONLY in PHP utilizing the - SOLID acronym - principles! Does anyone know of the absolute best, most recent PHP book that utilizes the SOLID principles and GRASP, and all the other best practices? I want to learn from the best possible source! Not beginner books! I already understand OOP. This seems like an almost impossible question to find the answer to and so I thought, hey, might as well post on stackexchange!! Surely someone out there must know!!!!!!!!!! Or if noone happens to know, Maybe they know of an open source application that utilizes these principles that is relatively small that is not a framework. Something that I can go through every single class, and spend time understanding the insides and outs of how the program was developed. Thanks so much in advance! I really really really really appreciate it! Well it looks like we aren't supposed to ask about best books, so nevermind this question! Sorry about that!

• Deprioritize BitTorrent traffic

  - by Steven Xu

  I'm sure the question has been asked before, but I can't seem to find it for myself; my Google-fu eludes me. My router, the Linksys E2000, does a decent job at being reasonable about prioritizing some sorts of traffic above BitTorrent traffic (there isn't too much interruption to port 80, 443, or 22 traffic, the ones I use most often). But other ports get pummeled. For instance, 3000 (which I use for local Rails testing) becomes almost entirely non-functioning. Xbox Live traffic (not sure about the ports, but they are in the 1000 range) doesn't do well either. So I'm wondering how to ensure that XBL and local Rails testing maintain strong service while BitTorrent is going. Is it enough that I turn up the QoS on their associated ports to high? It doesn't seem to be as effective as when BitTorrent isn't running at all (I don't know if there's a way to deprioritize BitTorrent traffic).

• What is causing a vm to exhibit packet loss?

  - by Joe Philllips

  We have a pretty nice piece of hardware set up to run multiple virtual machines in vmware and one of the vm's is an instance of Windows Server 2003 running SQL Server 2005. For some reason we occasionally see 10-20 seconds of straight packet loss to this machine from remote machines (my workstation) as well as other vm's on the same physical hardware. I am using PingPlotter to keep a close eye on the packet loss. So far we've turned off flow control on the NIC but we are already running out of other things to try. What might be causing this and how can I identify the problem? Note: We also have another server with a very similar configuration with the same type of problem to a lesser extent (because its not used as heavily?)

• No boot or grub file after using ls command

  - by Poke Moke

  I had xubuntu installed, i believe version 12.04 and then tried to dual boot with backbox. It worked from the flash drive but upon installing it onto the hard drive, I could no longer boot backbox. I decided I would just clear my OS and put just backbox on the hard drive and only have a single boot. To do this, I erased my boot file completely which led to my current position. I am put into the grub rescue prompt. I can't do a system restore, I can't boot with anything I might try including puppy linux and a boot rescue, and I've looked up the commands and I've tried to fix this. I can do ls, I find the correct hd but then I'm stuck as I don't have a boot or grub folder. The command is typed as: ls (hd1,msdos1)/ and listed is ./ ../ lost+found/ etc/ media/ bin/ dev/ home/ lib/ mnt/ opt/ proc/ root/ run/ sbin/ selinux/ srv/ sys/ tmp/ usr/ var/ initrd.img vmlinuz cdrom/ apfolder initrd.img.old vmlinuz.old (not sure if it's initrd or init rd.img. as it wraps around the screen there.) I've seen commands regarding boot or grub if they are seen but as listed, they aren't there. Any ideas?

• Sources of NetBeans Gradle Plugin

  - by Geertjan

  Here is where you can find the sources of the latest and greatest NetBeans Gradle plugin: http://java.net/projects/nb-api-samples/sources/api-samples/show/versions/7.1/misc/GradleSupport To use it, download the sources above, open the sources into the IDE (which must be 7.1.1 or above), then you'll have a NetBeans module. Right-click it to run the module into a new instance of NetBeans IDE. In the Options window's Miscellaneous tab, there's a Gradle subtab for setting the Gradle location. In the New File dialog, in the Other category, you'll find a template named "Empty Gradle file". Make sure to name it "build" and to put it in the root directory of the application (by leaving the Folder field empty, you're specifying it should be created in the root directory). You'll then be able to expand the build.gradle file: Double-click a task to run it. When you open the file, it opens in the Groovy editor, if the Groovy editor is installed. When you make changes in the file, the list of tasks, shown above, is automatically recreated. It's at a really early stage of development and it would be great if developers out there would be interested in adding more features to it.

• how to properly implement alpha blending in a complex 3d scene

  - by Gajet

  I know this question might sound a bit easy to answer but It's driving me crazy. There are too many possible situations that a good alpha blending mechanism should handle, and for each Algorithm I can think of there is something missing. these are the methods I've though about so far: first of I though about object sorting by depth, this one simply fails because Objects are not simple shapes, they might have curves and might loop inside each other. so I can't always tell which one is closer to camera. then I thought about sorting triangles but this one also might fail, thought I'm not sure how to implement it there is a rare case that might again cause problem, in which two triangle pass through each other. again no one can tell which one is nearer. the next thing was using depth buffer, at least the main reason we have depth buffer is because of the problems with sorting that I mentioned but now we get another problem. Since objects might be transparent, in a single pixel there might be more than one object visible. So for which Object should I store pixel depth? I then thought maybe I can only store the most front Object depth, and using that determine how should I blend next draw calls at that pixel. But again there was a problem, think about 2 semi transparent planes with a solid plane in middle of them. I was going to render the solid plane at the end, one can see the most distant plane. note that I was going to merge every two planes until there is only one color left for that pixel. Obviously I can use sorting methods too because of the same reasons I've explained above. Finally the only thing I imagine being able to work is to render all objects into different render targets and then sort those layers and display the final output. But this time I don't know how can I implement this algorithm.

• DOSBox 8.3 filenames disagree with Windows 7

  When I compare a dir in DOSBox 0.74 against a dir from Windows 7 command prompt, the 8.3 filenames differ. Long format (both drives and directories): 2012-07-30_abcdefg-abcde 2012-07-30_abcdefg-abcde.7z 2012-08-06_abcdefg-abcde 2012-08-06_abcdefg-abcde.7z 2012-10-22_IIS-LogFiles 2012-10-22_IIS-LogFiles.zip 2012-11-14_selective-abcde DOSBox 0.74 (dir): 2012-0~1 2012-0~3 2012-1~1 2012-1~3 2012-0~2 7Z 2012-0~4 7Z 2012-1~2 ZIP Windows 7 (dir /x): 2012-0~1 2012-0~1.7Z 2012-0~2 2012-0~2.7Z 2012-1~1 2012-1~1.ZIP 2012-1~2 so for instance if I'm passing in a path to DOSBox, sometimes this happens and whatever I'm trying to automate will fail. Why the difference, and can I change any settings to help DOSBox generate the correct shortnames?
