• How can I return something early from a block?

  - by ryeguy

  If I wanted to do something like this: collection.each do |i| return nil if i == 3 ..many lines of code here.. end How would I get that effect? I know I could just wrap everything inside the block in a big if statement, but I'd like to avoid the nesting if possible.

• how to compare files/directories of 2 separate solaris boxes ?

  - by chz

  Hi Friends I have 2 solaris boxes and I need to check certain directories (on local filesystem and mounted nfs) to make sure that they match up on both boxes and to delete or move the other mismatches to elsewhere on the local filesystem. I investigated for unix commands like rsync, and tree but it appears that these commands are not supported on my Solaris boxes. What is the best approach to this problem with the least pain to solve it ? to use rsync, tree and then diff the outputs or find ? I have trouble limiting the find command to certain directories as there are mounted folders that contain too many xml files that I don't care to much in that directory. What's the find command to search multiple directory paths on a single find command. Thanks Sincerely

• FTP Folder Permissions / IIS8

  - by raam030

  I am having trouble copying information from one folder on an FTP site to another folder. Accessing the FTP site from a windows explorer. I have set Full Control over the parent folder, and I double checked...I have full control over the two folders that is trying to copy information from and to. It actually lets you right click and copy. Then when you try to go to another folder and right-click and paste, the paste option is grayed out. I was able to do it before and no one has changed the IIS permissions. I believe it's a Windows issue. Is it possible that even though the permissions are set to give full control over that directory, that something else is interfering? I did double check the IIS permissions. I am not on a domain, using anonymous access, made sure the access control is set to read/write.

• Bootcamp: setup of Windows 7 (64 bit) hanging at "disk.sys"

  - by Skade

  I am having trouble getting Windows 7 Professional (64bit) to install on a Macbook Pro (late 2010 model). The installer hangs when loading the setup from disk. When restarting, I get an option to boot Windows from disk. The installer then starts loading files from disk and suddenly hangs. Using "Safe Mode" (from the advanced menu), it tells me that the installer hangs when loading "disk.sys". The installation is made on a fresh Bootcamp partition, the disk uses GPT. Has anyone seen this before and maybe found a solution?

• Should you archive documents before backing up to the cloud?

  - by gabbsmo

  I'm planning to add a cloud storage to my personal backup strategy. But now I wonder if it really is worth the trouble of compressing my documents and photos. The Open XML-format already have zip-compression and JPEG is a lossy image format. So there really isn't much benefit in compressing. 20Mb of documents become about 17Mb at the ULTRA preset of 7-zip. One benefit I can imagine is that you can shorten upload time by archiving the folders since it minimizes the number of requests that is needed to be sent to the server at upload and download. So what are your thoughts and experience in this issue? Should you archive your documents before backing them up to the cloud?

• 'Unlimited' free trial of Windows Server 2008 by deleting and reinstalling VM? [closed]

  - by MrVimes

  I am using Virtual Machine software (VirtualBox) to learn Windows Server 2008 R2 Network Infrastructure (70-642). Trouble is - I'm learning at an extremely slow pace and so the trial periods of my virtual machines are close to running out. If I delete the VMs then install WS2008R2 from scratch on new VMs is that violating the acceptable use policy of Microsoft? I am aware that I can extend the trial, but it seems I can only do that by 10 days at a time. Also I think having to re-install from scratch is a good way to reinforce the knowledge.

• Getting started with unit testing in VS2010?

  - by Herb Caudill

  I'm new to both unit testing and Visual Studio 2010 (just upgraded from 2008). I'm interested in using VS2010's new built-in unit testing tools, but would like to get the lay of the land first. I haven't been able to find any resources or tutorials on unit testing with VS2010 specifically - has anyone found a good walk-through? I'm also open to persuasion that we should stick with NUnit or the like, if anyone knows a reason to avoid the built-in tools.

• Mouse will not click and drag

  - by C. Ross

  My mouse is currently having trouble with Click and Drag. It moves well, it clicks well (including double click); but it will not click and drag correctly. When dragging it just drops the highlighted area almost immediately after starting it. The operating system is Windows 7 x6, and the mouse is a Microsoft 5 Button laser wired model that's approximately 3 years old. The problem is relatively new, but has been happening consistently for several weeks through several reboots. Is there anything to try besides buying a new mouse?

• Working with the IE cache from C# & WPF

  - by Eric

  I'm writing a program in C# using the WPF framework. I need to display images, and I'd like to cache them to avoid downloading them constantly. I can code my own cache, however, IE already has a caching system. I can find code to read entries out of the IE cache, however I've found nothing dealing with the issue of adding items to the cache. Is there a good way to do it, or should I just implement a separate cache?

• Avoiding dependency carrying

  - by dotnetdev

  When coding, I often come across the following pattern: -A method calls another method (Fine), but the method being called/callee takes parameters, so in the wrapping method, I pass in parameters. Problem is, this dependency carrying can go on and on. How could I avoid this (any sample code appreciated)? Thanks

• recommendations for disk -> usb backup software

  - by TWood

  Recently I lost a tape drive and rather than repair the unit I decided that backups to usb external drives would be cheaper. In the past I used NTBackup and figured that the new server 2008 R2 backup wbadmin utility would be able to meet my needs. It does not. I am looking for recommendations for another utility that i can use. My requirements are: -backup local disk in addition to files on a network share -scheduled task integration (or some gui options to manage schedule) -non-incremental backup Basically I could do this all with WBAdmin if it just supported network shares. I saw some links that described attaching a vhd pointed to a network share but I am trying to avoid hacks like that. If i'm going to do all that trouble I'd just as well manually copy the directories over myself. If anyone has any software suggestions that might make this task easier for me let me know please. I am considering BackupAssist but can only find a few reviews here and there for it.

• Issues with new graphics card and drivers

  - by Ortund

  With my onboard graphics card (Intel HD 4000) I was able to use 1680x1050 screen resolution. Using the same screen and an Asus ENGTS250 graphics card with 296.10 drivers installed, I'm not able to use that resolution anymore. Also, I've been having other trouble with driver installations. Using 340.52 or 337.88, I can't boot into Windows 7. I see the Windows Welcome screen and then the screen goes black, loses signal and the computer locks up. I think the drivers issues and the resolution problems go hand-in-hand. I have a feeling I could use a newer driver than 296.10 which would give me access to use the 1680x1050 resolution I want to use, but I'm terrified that if I update or install another driver, that the computer will lock up again. Can anyone recommend a [better] driver for me to use?

• How to install a mmc certificate on Windows?

  - by Alex

  I am not familiar with Windows very much, and I have trouble installing a MMC certificate. I am following this description to use MMC to create a certificate, but I cannot complete the step labeled ' Install or view the certificates under:'. There is nothing unter 'ConsoleRoot' - 'Certificates (Local Computer)' - 'Personal', and when I try to find the certificate I cannot find it. There is another page with nice screenshots, which works until step 9 when I am about to choose the certificate file. I do not know where this file is been created, if at all. How can I create/install/import this certificate? I require this in order to use the powershell Enter-PSSession from a remote machine...

• No IO exception reported for socket operation when the interface is removed

  - by user352536

  The wifi network is connected, the application setup a socket connection and exchange data with the remote server. But when turn off the wifi, the inteface is removed, while socket operation read/write on this socket is still like normal, no any IO exception reported. The application has to do some extra checking to avoid waiting for the data forever. Is this the normal case for Android design? Is there any plan to fix it?

• Using a Group Managed Service Account (gMSA) for a scheduled task

  - by Trevor Sullivan

  Back in Windows Server 2008 R2, when stand-alone Managed Service Accounts (sMSA) were new, they could not be used to execute scheduled tasks. In Windows Server 2012 however, there is a new type of account called the Group Managed Service Account (gMSA). This type of account is supposedly capable of launching scheduled tasks in the task scheduler on clients & member servers inside of a Windows Server 2012 forest/domain functional level. So far, I have: Established a Windows Server 2012 forest/domain Created a Group Managed Service Account (gMSA) Installed the gMSA on a Windows Server 2012 member server And currently I'm having trouble with: Setting a scheduled task to use the gMSA When I attempt to use a gMSA on a scheduled task, I get the error message that says "The object cannot be found" (paraphrased) message. My question is: How do I configure a Scheduled Task to execute using a Group Managed Service Account (gMSA)?

• I would like to pipe output of find into input list of scp, how?

  - by user13184

  I'm a novice linux user and I am trying to send a long list of files from one computer to another. The argument list is too long, so I am using find. I am having trouble setting up the expression, though. Can someone help? Here is what I would normally type for a short argument list. scp ./* phogan@computer/directory... Here's I think this might translate into with find. scp find . -name "*" phogan@computer/directory... Maybe I could use piping? Any suggestions would help. Thanks in advance.
