• How can I get all my itunes files from multiple computers onto my new PC?

  - by jasondavis

  Managing my itunes files (music,video,tv shows, iphone apps) is a really hard task and I have not had much luck yet. If I had a single PC for the rest of my life with the same hard drive, it would work great but infortunately it cannot be that simple. I just build a new PC as my old hard drive crashed with all my itunes purchased songs, video, etc. So is there anyway to get itunes to recognize that I own all them and let me re-download everything? As I see it so far, it knows what I own by my itunes account login (it knows if I purchased a file or not ever) but does not seem to let you just re-download everything to a new PC or new hard drive. I realize I should of had backups but I didn't. My backup plan is a work in process and it is getting much better but that doesnt help with my situation at the moment. So I am asking for any help, ideas of how to retrieve all my previous itunes purchases?

• batch file to disable network share on Windows XP

  - by Robb

  Loosely related to this question Network Share causing Cygwin to run slowly after 'ls', I'd like to write a little batch file that I can execute to disconnect the host from any network shares and subsequently another batch file to reconnect. Ideally, this would be something that I can execute from a PuTTY terminal, SSHed into the box running cygwin. I'm pretty sure the batch files can be written easily, but I don't know about executing them from a PuTTY terminal. Regardless, I'd still like the batchfiles anyways. For the sake of simplicity my process would be: Log into server via PuTTY Run batch files to disconnect shares Do what I need to do Run batch files to reconnect shares Exit session, closing PuTTY

• Automatic profile load on boot

  - by AnthonyW

  Is there any way to configure a computer to login automatically at bootup and then IMMEDIATELY switch users? The purpose is to trigger the profile loading process for the assumed user so that when they go to login, their profile loads instantaneously. Yet, the immediate user switch means that the login password is still required before any actual use. A few of the attempts I have made require storing the password in plain-text for the system to use. Needless to say that is undesireable. I have been looking for this solution for years; if anyone knows of a better solution to skinning this cat I am all ears. EDIT: tsdiscon command will Lock the workstation.

• Computer to act as keyboard

  - by Joe

  Title explains it. Imagine this example, Host computer connects to a Client computer via male/male usb connection. Client computer acknowledges this connection as a new device, in this case a keyboard. The host computer can now send key events to the client computer and the client computer would process them as a normal keyboard event. I did a whole lot of searching in the internet and really have drove down many dead ends. Any tips would be appreciated. Note* this is a physical connection. The client computer should not have to install any software for this to function (The host will completely spoof as a keyboard).

• Client and Server game update speed

  - by user20686

  I am working on a simple two player networked asteroids game using XNA and the Lidgren networking library. For this set up I have a Lidgren server maintaining what I want to be the true state of the game, and the XNA game is the Lidgren client. The client sends key inputs to the server, and the server process the key inputs against game logic, sending back updates. (This seemed like a better idea then sending local positions to the server.) The client also processes the key inputs on its own, so as to not have any visible lag, and then interpolates between the local position and remote position. Based on what I have been reading this is the correct way to smooth out a networked game. The only thing I don’t get is what value to use as the time deltas. Currently every message the server sends it also sends a delta-time update with it, which is time between the last update. The client then saves this delta time to use for its local position updates, so they can be using roughly the same time deltas to calculate position updates. I know the XNA game update gets called 60 times a second, so I set my server to update the game state at the same speed. This will probably only work as long as the game is working on a fixed time step and will probably cause problems if I want to change that in the future. The server sends updates to clients on another thread, which runs at 10 updates per second to cut down on bandwidth. I do not see noticeable lag in movement and over time if no user input is received the local and remote positions converge on each other as they should. I am also not currently calculating for any latency as I am trying to go one step at a time. So my question is should the XNA client be using its current game time to update the local game state and not being using time deltas sent by the server? If I should be using the clients time delta between updates how do I keep it in-line with how fast the server is updating its game state?

• High-level description of how experimental C++ features are developed?

  - by Praxeolitic

  Herb Sutter in a video answers a question about the concepts proposal considered for C++11 and from his remarks it sounds like multiple groups offered prototype implementations but all of them left concerns about slow compile times. The comment surprised me because it suggests that, at least in some cases, the prototypes being developed are not just proofs of concept -- they're even expected to perform. All the work that must take has me curious. For mature languages, especially C++, how are experimental language features developed? Is it much different from developing a compiler that implements a standard? Does a developer have a sense of if it will work and perform or even if it ever could? What are the most time consuming parts and are any parts surprisingly easier than one might expect? The question is not what does the C++ standards committee do, but rather the part that comes before. When an experimental implementation for a proposal is being put together and there aren't any completely solidified rules, how is the sausage made? I'm not a professional compiler developer nor do I expect answers with step by step accounts. I'd like a high-level idea of how this would be done or if there are any general patterns at all. I don't know what to expect from the answers but even if there are no rules to the process and the small number of people who do this just cowboy it and then, for stuff that worked out, write up the "official version" as a proposal, that answer would still be informative.

• How to install a new TFS checkin policy on a TFS 2010 server?

  - by rayrayrayraydog

  We've recently upgraded our TFS server to TFS 2010 from 2008. We've been researching a couple new add-on checkin policies we want to install. The only problem is that all documentation I can find on adding new policies to the server appears to be specific to TFS 2008 or earlier. Those steps involve adding new keys in the registry which do not exist on our 2010 TFS server. Does anybody know where the process to install new checkin policies on a TFS 2010 server so they can be applied to Team Projects is documented? Thanks!

• One subdomain is not working

  - by BFTrick

  Hello there, My main domain works just fine - www.example.com and a subdomain set up by another developer works as well - sub1.example.com. But when I try to set another subdomain up I go through the process everything seems to work. The software creates the default files where the subdomain files should go. But when I try to browse there it doesn't work. My host uses Plesk to do all of the hosting stuff. What do you think the problem is? I doubt it is some sort of cache issue because I had problems on my phone which I tried after problems on the pc. Maybe for some reason Plesk needs time to set this up? I have used Cpanel before and that works instantly.

• MacPorts on mountain lion - cannot install apache2 due to gettext package

  - by jancha

  I have been having problem with installing gettext package from macports. When I am launching /opt/local/bin/port -v install apache2 it checks dependencies, and continues with gettext package installation. But the configure process freezes here: checking for egrep... /usr/bin/grep -E and nothing happens.. can wait hours, nothing changes. I tried to configure, make, make install manually for that package and it went all fine. But, when same configure is launched by ports, it hangs there. Question: 1) How can that be fixed? 2) Maybe I can somehow manually tell ports, that I installed that gettext package manually already? Sorry, if wrong "site" for this question. Felt most proper one.

• Hyper-V: determine the guest's name given the GUID

  - by syneticon-dj

  How would I go about determining the guest's name given its GUID or vice-versa, preferably with only the Hyper-V/Server Core stock install at hands? Rationale: I am in favor of having a repository of dirty tricks to revert to when in great need. To immediately quiesce all (storage) operations of a VM guest without losing the state, I used to run kill 17 <all VM's virtual processes> (signaling SIGSTOP) and resumed afterwards using kill 19 <all VM's virtual processes> (signaling SIGCONT) in ESXi/vSphere shell. I tried the same technique with Hyper-V using Process Explorer's "Suspend" functionality on the vmwp.exe processes and it seemed to work. I have yet to find a way for easily identifying the processes to suspend, though - the vmwp command line is only listing a GUID.

• Install Firefox on Windows 7 for all users

  - by Pointy

  This has got to be among the simplest possible things in the word for those who know how to do it. However, I don't, and I have been astonished to find nothing about it from google searches other than unanswered copies of the exact same question. All I want is Firefox, and I want it for all users on a Windows 7 laptop. In fact, the real story is that I want it to work again for all users after updating from Firefox 5 to Firefox 8, which process has apparently left it unavailable to anybody but the administrator. I'll probably find the answer to this in the time it takes for this question to get answered, but I promise I'll upvote you anyway :-) I mainly wanted to get this question (hopefully with good answers) out there so that it turns up on a Google search.

• How do I stop my IIS App Pool making a request to wpad.mydomain.com?

  - by Programming Hero

  As part of some performance troubleshooting, I've monitored the slow startup of a "cold" App Pool (one without an active worker process) in IIS. When using a built-in account, the App Pool starts in sub-second time. When using a custom local account the App Pool takes 30+ seconds to start processing requests. The service appears to be making requests to wpad.mydomain.com, an address it does not have access to, which causes it to wait 30 seconds for a response before eventually timing out. As a workaround, I've added the hostname to the server's hosts file, to direct the traffic to the local machine, which returns much faster (1-2 seconds). What do I need to do to stop IIS making this request when this identity is used for the App Pool?

• Is Clonezilla a good option for a daily batch-file-based backup of a Windows XP PC?

  - by rossmcm

  Having just been through the process of rebuilding a Windows XP desktop machine when the disk died, I'm anxious to make it a lot less painful. I didn't lose any data, but reinstalling everything took ages. Clonezilla seems to be a highly mentioned free backup tool. How easy would it be to implement the following: a nightly unattended backup of the desktop's disk image to another network machine (or a second drive in the machine), hopefully with compression. restore from that image using USB boot media. so that if I come in to work and find the hard drive has tanked, it is just a matter of replacing the dead drive with a new one, booting from the USB stick, choosing the image to restore, and then finding something else to do for an hour or two. When it is finished I would hopefully be back to where I was.

• What makes one language any better than another when both are designed for the same goals? [closed]

  - by Justin808

  I'm in the process of creating a grammar for a scripting language but as I'm working on it I started to wonder what makes a language good in the first place. I know the goals for my script but there are always 1000 different ways to go about doing things. Goals: Easy to use and understand (not my grandma could do it easy, but the secretary at the front desk could do it or the VP of marketing could do it type of easy) No user defined functions or subroutines. Its use would be in events of objects in a system similar to HyperCard. Conceptually I was thinking of a language like this: set myVariable to 'Hello World' set counter to 0 repeat 5 times with x begin set counter to counter add x end set myVariable to myVariable plus ' ' plus counter popup myVariable set text of label named 'label' to 'new text' set color of label named 'label' to blue The end result would popup a dialog with the contents Hello World 15 it would also change the text of a label and make it blue. But I could do the same thing 1000 different ways. So what makes one language any better than another when both are designed for the same goals?

• Error installing SQL Server 2005 Express on AMD Turion?

  - by Angel

  Hello. Is there some compatibility problem between SQL Server 2005 Express and AMD processors? I read something along those lines on various sites, but found nothing 100% definitive. I am trying to install SQL Server 2005 Express on a computer that runs Windows Vista Home Premium, 32-bit edition, and the CPU is "AMD Turion Dual-Core RM-70". I tried both the 32-bit and 64-bit installers, just in case, and the process runs fine until the moment the service attempts to start, where it fails with the same error every time. I'm sorry I can't provide more details or the exact message, it was on a client computer to which I have no access at the moment. I hope someone could shed some light on this. Thank you.

• Nginx and low-speed connections: request terminates after 253 seconds

  - by meze

  I'm trying to make nginx to handle static files. All is working fine except that when I throttle my connection speed to 8kbit/s, the loading process of a file just stops after 253-255 seconds (4.2 min according to chrome). No error in the log, the status code is 200 but the response is received partially. If I disable nginx and make apache to send the same file - it loads successfully after 10 minutes. The config I use for debugging is: client_header_buffer_size 16k; large_client_header_buffers 4 8k; client_max_body_size 50m; client_body_buffer_size 16k; client_header_timeout 20m; client_body_timeout 20m; send_timeout 20m; Did i miss some configurations?

• Setup Email Server (sendmail + dovecot + squirrelmail)

  - by henry

  I am in the process of setting up my very first email server. I can get everything up and running (thanks to apt-get). Manage to tie the users with system users. Now I am setting up virtual users for dovecot. But however, I also notice I can setup users in sendmail itself. Why is it so that you can setup users in 2 different places. Other mail server will send to the user in sendmail or dovecot?

• My webcam just came on "out of the blue"

  - by AngryHacker

  I have a Microsoft LifeCam HD sitting atop my monitor. Today, completely out of the blue, its light came on -- I was simply browsing the web (in Chrome) when it happened. After about 5 minutes the webcam turned off. Naturally, I immediately suspected my ex-wife (when in doubt, I always suspect her), but she isn't computer savvy enough. I looked over the process list and didn't see anything suspicious. I am running a couple of open source projects and free apps (e.g., greenshot, powermenu, supertray), but I've had them for years. Autoruns reports nothing suspicious in the startup and neither does Windows Defender. Anyways, what could it be? What should I look at next?

• BackupPC back-up has not been finished in 12 hours(!)

  - by chronoz

  I installed BackupPC toda on a server and set it to do a back-up 12 hours ago... while it's been backing up since, it seems very very slow and it's not completed yet. It's just backing up a testserver with a total disk usage of 1.8GB. What could cause the back-up process to be so slow? rsnapshot always worked wonderfully fast, but I want to improve my back-up solution. df shows that the size on the back-up disk is actually still increasing.

• Freeze during Battlefield 3 - Probable Hardware issue?

  - by HendsteR

  my friend's notebook frequently freezes during BF3 sessions since ~1 1/2 months. It runs Win764Bit and he already reinstalled windows during the process, it didn't help. So we guess it might probably be a hardware issue. Now the question - which part of the hardware could effect a total freeze of the system WITHOUT getting a bluescreen? Or are there any known software issues he could also try? The hardware specs are: Acer 7745G Intel i7 720QM AMD Mobility 5850HD - Running Catalyst 11.6 now btw. (all drivers tested from 11.2 to 12.6 though) 4GB Ram 1.333MHz Oh and yeah, he just added that it crashes playing Diablo3 from time to time, too. Please help :)

• Is Reading the Spec Enough?

  - by jozefg

  This question is centered around Scheme but really could be applied to any LISP or programming language in general. Background So I recently picked up Scheme again having toyed with it once or twice before. In order to solidify my understanding of the language, I found the Revised^5 Report on the Algorithmic Language Scheme and have been reading through that along with my compiler/interpreter's (Chicken Scheme) listed extensions/implementations. Additionally, in order to see this applied I have been actively seeking out Scheme code in open source projects and such and tried to read and understand it. This has been sufficient so far for me understanding the syntax of Scheme and I've completed almost all of the Ninety-nine Scheme problems (see here) as well as a decent number of Project Euler problems. Question While so far this hasn't been an issue and my solutions closely match those provided, am I missing out on a great part of Scheme? Or to phrase my question more generally, does reading the specification of a language along with well written code in that language sufficient to learn from? Or are other resources, books, lectures, videos, blogs, etc necessary for the learning process as well.

• Adding custom script on ESXi 5.0

  - by Quzar

  I have an ESXi server that I would like to have run a custom script on every boot that contains esxcli and other commands. I have tried adding the script into init.d and creating an rc.local.d folder with a script, but the etc folder gets rebuilt on startup. I've also tried modifying state.tgz and local.tgz in the /bootbank folder in order to force these files to appear, but that does not seem to work either. Is there any way I can run custom commands on boot? Note: I've tried the advice here ESXi boot process / state storage to no avail. Seems the system was changed between 4.1 and 5.0

  I've taken a look at the setup and configuration process for a Postfix server, planning to use it for just sending emails out from my server. So far, I have these steps: Setup Postfix Configure Postfix Install DKIM Set SPF records Tune for performance Debug Seems rather straightforward. However, I was just wondering: are there any actions I should be taking for periodic maintenance of my Postfix setup? Thanks! EDIT: Also, just curious, how long would this entire setup ideally take? 30 - 60 minutes? More?
