• Sennheiser PC360 Microphone Suddenly Stopped Working

  - by Michaelwm

  Just recently, my Sennheiser PC360's microphone stopped working. Yesterday Night, it was working 100% fine. Muting correctly, un-muting, volume boosting, etc. I woke up this morning, and got into a skype call (After not changing a single setting on my computer), and it wasn't working. I tried mumble, and it didn't work there either. After that, I checked my sound devices and found out it was plugged in, but not responding to my voice. I unplugged the headset, and it correctly showed that it was unplugged. So, a quick run-down: Sennheiser PC360 Headset suddenly stops working after a few hours of sleep. Software is up to date I can hear the mute sound when I raise and lower the microphone arm Windows Sound Device Manager shows that it is plugged in Unplugging the headset correctly shows it is unplugged Windows Sound Device Manager shows that the microphone isn't receiving any input

• Is IDirectInput8::FindDevice totally broken on Windows 7?

  - by Noora

  I'm developing on Windows 7, and using DirectInput8 for my input needs. I'm tracking gamepad additions and removals (that is, GUID_DEVINTERFACE_HID devices) using the DBT_DEVICEARRIVAL and DBT_DEVICEREMOVECOMPLETE messages, which works fine. However, what I've come to find out is that no matter what I do, passing the received values from DBT_DEVICEARRIVAL to IDirectInput8's FindDevice method, it will always fail to identify the device, returning DIERR_DEVICENOTREG. DirectInput still clearly knows about the device, because I can enumerate and create it just fine. I've tried with three different gamepads, and the error persists, so it's not about that either. I also tried passing some alternative interface GUIDs for the RegisterDeviceNotification call, didn't help. So, has anyone else faced the same problem, and have you found a usable workaround? I'm afraid I'll soon have to stoop down to re-enumerating all devices when something is added or removed, but I'll first give this question one last shot here. EDIT: For the record, I've also tried pretty much every single HID API & SetupAPI function for alternative ways of figuring out the needed GUIDs, with zero success. So if you're facing the same problem as me, don't bother with that route. I'm pretty sure those GUIDs are made up by DirectInput itself somehow. Short of reverse engineering dinput8.dll, I'm truly out of ideas now.

• Is there any way to remotely configure a Microsoft Lync account?

  - by John O

  There are no perl modules for Lync. No open source clients. Windows Powershell can do some things with it, but only on the server on which the server software is installed. It would be useful to be able to forward a certain desk phone number (we use Lync for voip) to a personal cell phone. We can do this from our own desktop machines, but only using the Lync client. It would be nice to be able to have a cron script run that just did rotations, I wouldn't have to carry around the lousy on-call phone with me. communicator.exe doesn't take any useful parameters. Nor are there any obvious function names in the DLLs that would let me just use rundll32.exe to accomplish this. There is a Lync SDK, but no examples of changing phone forwarding, and my Windows 7 machine refuses to install the Silverlight SDK dependency for some reason I can't fathom. Does anyone have any other ideas how I might accomplish this?

• Pausing a song in iTunes using the space bar no longer works after upgrade to Lion

  - by Snap Shot

  I used to be able to switch to iTunes using cmd-tab and press the space bar to pause a song as it was playing. This allowed me to to stop the song quickly when I was interrupted by a phone call. However, this no longer works. I can only go to the Controls menu item in iTunes and select Controls -- Pause. I do see that the menu item "Pause" is mapped to "space". When I press the space bar now with iTunes as the "active" application I just hear a tone. Recently I upgraded both Lion and iTunes so I am not quite sure which one stopped this from working properly. Does anyone know how to get this functionality back?

• Computer not booting, black screen, no beeps

  - by Michael Gaddass

  I bought a pre-owned computer on Ebay. It booted fine, had to reset due to it not detecting USB mouse, but it detected the USB keyboard. Booted fine again, then I tried to install Ubuntu Desktop, when it was installing I got a phone call, when I'm answering it, I find a Blue screen of Death. I reboot the computer and nothing, no BIOS boot, no beeping, but one of the fans was on. I opened the cover and found a large amount of dust, removed it, still not booting. I'm a complete novice with computer repairs, the most advanced thing I did was take a 286 harddrive and replace a 486's damaged harddrive with it (put the drive into the 486 that is), what could possibly be causing this?

• I can't see wordpress .php file?

  - by Alegro

  I installed WAMP server on win xp - it works. I installed Wordpress 3.4.2 into www.wordpress - no problem. In Dreamweaver CS5 I created a site with www.wordpress as root folder, and assigned a local test server - ok. In Dreamweaver, I opened twentyten theme - index.php - and pressed F12 to see the page in Firefox - and got: Fatal error: Call to undefined function get_header()... - on line 16 This is a completely new and clear wordpress installation. Why is the function (get_header) - undefined? To check the server I copied another .php file into the same folder - F12 - it works.

• Context-specific remap

  - by dotancohen

  I have the following handy VIM map: inoremap ( ()<Left> However, sometimes I will enter Insert mode to add a function call around a variable, like so: Was: $sql = "SELECT * FROM " . $someTable; To: $sql = "SELECT * FROM " . mysql_real_escape_string($someTable); The mapping makes a redundant ) after mysql_real_escape_string(. Is there any way to refactor the mapping so that if there exists a character after the cursor, and the character after the cursor is not whitespace, then )<left> is not appended to (? Thanks.

• Active Directory management with low user rights

  - by DemonWareXT

  Our problem: The client, a normal user, has to be able to reset multiple passwords at once. Around 30 in one go. This would call for powershell or something along these lines, but for AD and Powershell one needs to be domain administrator. My solution would be to make a service that runs on the AD server and take connections from a program. The service would then do the AD changes. So far so good, I would just like to hear some other thoughts on this problem. Because I sure can't be the only one with it

• JavaScript and the User Experience

  5 sites I commonly vist at home: Google.com Gmail.com Linkedin.com Capella.edu Codeplex.com All of the top 5 sites I visit at home use JavaScript and is applied in various ways for various reasons. Gmail and Google make use of Ajax to retrieve information without the user having to call another page. In addition, all 5 of the websites use JavaScript to enhance a user's experience. Examples of this can be found in content rotation on Capella's main site and the displaying and hiding of specific content sections from within our course room. Codeplex uses Ajax and JavaScript to show dynamic content on its homepage and allow users to page through the data. I think there use of JavaScript is well placed and enhances the viewing experience of the user because it reduces the amount of interaction a user has to perform for them to obtain information they are looking to see. I have used JavaScript in various ways. One of the most memorable ways was to enable an HTML table to be able to have its rows paged and sorted based on the values in each table row.

• Helping to Reduce Page Compression Failures Rate

  - by Vasil Dimov

  When InnoDB compresses a page it needs the result to fit into its predetermined compressed page size (specified with KEY_BLOCK_SIZE). When the result does not fit we call that a compression failure. In this case InnoDB needs to split up the page and try to compress again. That said, compression failures are bad for performance and should be minimized.Whether the result of the compression will fit largely depends on the data being compressed and some tables and/or indexes may contain more compressible data than others. And so it would be nice if the compression failure rate, along with other compression stats, could be monitored on a per table or even on a per index basis, wouldn't it?This is where the new INFORMATION_SCHEMA table in MySQL 5.6 kicks in. INFORMATION_SCHEMA.INNODB_CMP_PER_INDEX provides exactly this helpful information. It contains the following fields: +-----------------+--------------+------+ | Field | Type | Null | +-----------------+--------------+------+ | database_name | varchar(192) | NO | | table_name | varchar(192) | NO | | index_name | varchar(192) | NO | | compress_ops | int(11) | NO | | compress_ops_ok | int(11) | NO | | compress_time | int(11) | NO | | uncompress_ops | int(11) | NO | | uncompress_time | int(11) | NO | +-----------------+--------------+------+ similarly to INFORMATION_SCHEMA.INNODB_CMP, but this time the data is grouped by "database_name,table_name,index_name" instead of by "page_size".So a query like SELECT database_name, table_name, index_name, compress_ops - compress_ops_ok AS failures FROM information_schema.innodb_cmp_per_index ORDER BY failures DESC; would reveal the most problematic tables and indexes that have the highest compression failure rate.From there on the way to improving performance would be to try to increase the compressed page size or change the structure of the table/indexes or the data being stored and see if it will have a positive impact on performance.

• Static / Shared Helper Functions vs Built-In Methods

  - by Nathan

  This is a simple question but a design consideration that I often run across in my day to day development work. Lets say that you have a class that represents some kinds of collection. Public Class ModifiedCustomerOrders Public Property Orders as List(Of ModifiedOrders) End Class Within this class you do all kinds of important work, such as combining many different information sources and, eventually, build the Modified Customer Orders. Now, you have different processes that consume this class, each of which needs a slightly different slice of the ModifiedCustomerOrders items. To enable this, you want to add filtering functionality. How do you go about this? Do you: Add Filtering calls to the ModifiedCustomerOrders class so that you can say: MyOrdersClass.RemoveCanceledOrders() Create a Static / Shared "tooling" class that allows you to call: OrdersFilters.RemoveCanceledOrders(MyOrders) Create an extension method to accomplish the same feat as #2 but with less typing: MyOrders.RemoveCanceledOrders() Create a "Service" method that handles the getting of Orders as appropriate to the calling function, while using one of the previous approaches "under the hood". OrdersService.GetOrdersForProcessA() Others? I tend to prefer the tooling / extension method approaches as they make testing a little bit simpler. Although I dependency inject all my sourcing data into the ModifiedCustomerOrders, having it as part of the class makes it a little bit more complicated to test. Typically, I choose to use extension methods where I am doing parameterless transformations / filters. As they get more complex, I will move it into a static class instead. Thoughts on this approach? How would you approach it?

• Batch script to create home home directories from list of names

• How to execute a scheduled task with "schtasks" without opening a new command line window ?

  - by Misha Moroshko

  I have a batch file that creates a scheduled task using schtasks like this: schtasks /create /tn my_task_name /tr "...\my_path\my_task.bat" /sc daily /st 10:00:00 /s \\my_computer_name /u my_username /p my_password It works OK except the fact that when my_task.bat is executed - a new command line window is opened (and closed after execution). I would like to avoid opening this new window (i.e. to run the task in quiet mode, in the background). I thought to use start /b ...\my_path\my_task.bat but I don't know how, because since I have to call start from the batch file I need to precede it with cmd /c, which again causes the new window to open. How could I solve this problem ?

• Dental adventures ...

  - by nospam(at)example.com (Joerg Moellenkamp)

  Today my dentist pulled all the stops. Really. Just to explain ... half a year ago or so, i got the base part of an dental implant in my jaw. Today i got the teeth ... beside other things. At first i made the acquaintance of a really weird instrument to remove a temporary tooth crown ... it's called "Hirtenstab" in german ... or "crown remover" in english ... i would call it tool of torture. After the fourth time using it, the temporary flew through the room and the final crowns were set on two teeth left and right of the implant. But the strangest instrument i saw was the instrument to fix the abatement (the thing between the crown and the screw thread implanted in the jaw). They really use a torque wrench (albeit a really small one) to screw the abatement into the jaw. Well .. at least i have a zirconium dioxide smile now ...

• Can NFS be forced to refresh stale files/directories when not using noac on the mount?

  - by johnnycrash

  We mount without using noac. I have a file that I append to once every 20 minutes. Then it will be read with mmap about 5,000 times a minute. We only mmap a couple blocks for each read. Needless to say, noac just kills the access performance, so we don't use it. I add data to the end of the file using a mount with noac and read from a mount without noac. The mounts that are reading are not seeing the new data. I want to know if there is a function I can call from c to refresh the attributes of a path and all its files. EDIT: I should add we cannot mount and unmount since there are 16 servers running on each system and they are constantly accessing the files. Well...maybe we could mount and unmount if each server used their own mount. I'd like to avoid that if possible. thanks!

• Using Ubuntu isn't worth it for me, Windows works best.

  - by user72475

  Welcome to Ubuntu and the lack of support( 12.04 LOS ). If I say Ubuntu 12.04 is a so so broken OS, I will get flamed. But if I ask for help, I can here the crickets chirruping. Unix/Linux user have an attitude and really don't like to share info. Because if they help everyone, they wouldn't have anyone to call a noob. Then their moms basement wouldn't be the same without being able to flame Ubuntu noobs. I am going back to windows I don't have to spend all day trying to get a single app or option to work. Sure Ubuntu is fun to tinker with but it is not a professional consumer OS. Windows is a better consumer based os, I don't need server software(Unix) that's been broken and hacked to be used like windows(Ubuntu). All the time I have wasted trying to get Ubuntu to work CORRECTLY cost me more the Windows 7 ultimate by far. HOW MUCH IS YOUR TIME WORTH. If you are unemployed and have all night to set in your moms basement and flame noobs then Ubuntu is for you. If you want to use an external monitor on your notebook or download Adobe reader use Windows 7. When are we going to stop complaining about corporate giants like Microsoft and admit they have great products. Gave it a shot, did work for me, I have better things to do with my time. bye Ubuntu

• RequireJS: JavaScript for the Enterprise

  - by Geertjan

  I made a small introduction to RequireJS via some of the many cool new RequireJS features in NetBeans IDE. I believe RequireJS, and the modularity and encapsulation and loading solutions that it brings, provides the tools needed for creating large JavaScript applications, i.e., enterprise JavaScript applications. &amp;amp;lt;span id=&amp;amp;quot;XinhaEditingPostion&amp;amp;quot;&amp;amp;gt;&amp;amp;lt;/span&amp;amp;gt; (Sorry for the wobbly sound in the above.) An interesting comment by my colleague John Brock on the above: One other advantage that RequireJS brings, is called lazy loading of resources. In your first example, everyone one of those .js files is loaded when the first file is loaded in the browser. By using the require() call in your modules, your application will only load the javascript modules when they are actually needed. It makes for faster startup in large applications. You could show this by showing the libraries that are loaded in the Network Monitor window. So I did as suggested: Click the screenshot to enlarge it and notice how the Network Monitor is helpful in the context of RequireJS troubleshooting.

• Multiple network cards, controlling where my traffic goes

  - by thefinn93

  This is an Ubuntu 12.04 server install. I have multiple network cards, eth0 and eth1 lets call them. eth0 is connected to the internet, and all of my traffic goes through it, until eth1 gets plugged in. Then the machine tries to send everything through eth1, which for various and sundry reasons does not go out to the Interent. The only traffic it doesn't send through eth1 is traffic on eth0's subnet. It also will not accept inbound connections on eth0 from outside of eth0's subnet. I'd like all outbound traffic to go out eth0, but I'd like incoming connections from to either card from any subnet to work.

• Java game design question (graphical objects)

  - by vemalsar

  Hello Guys, I'm beginner in game development, in Java and here on this site too and I have a game design question. Please comment my idea: I have a main loop which call update and draw method. I want to use an ArrayList which store graphical objects, they have coordinate and image or text to draw and my game objects extends this class. In update, I can choose which objects should be put in the array and in draw method I'll display the elements of array on the screen. I'm using a buffer and draw first there, but it is not important now I guess...Here is a simple (not full) code, only the logic: public class GamePanel extends JPanel implements KeyListener { ArrayList<graphicalObjects> graphArray = new ArrayList<graphicalObjects>(); public void update() { //change the game scene, update the graphArray, process input etc. } public void draw() { //draws every element of graphArray to a JPanel } public static main(String[] args) { while(true) { update(); draw(); } } } My questions: Should have I use interface or abstract class for graphicalObjects? graphicalObjects class and the ArrayList really needs or there is some better solution? How to draw objects? They draw themself with their own method or in the draw method I have to draw manually based on graphicalObjects variables (x,y coordinates, image etc.)? If this conception is wrong, please suggest another one! All comments are welcome and sorry if this is dumb question, thanks!

• How long does it take for a server to get 'off greylisting'

  - by Michael

  Hi all, I asked a question regarding email delays a few months ago, and I think I found a workaround. I changed our email from "[email protected]" to "[email protected]", and it seems to work instantly again. After reading some articles, I believe this could be due to some form of greylisting, though some servers might call it something else -- if a server like yahoo or gmail receive email from a server that it is not used to receiving email from, then sometimes the delay occurs. But a name such as yahoo, gmail, which requires a user to sign up manually -- this delay can be avoided. My question is this: does anyone know more about this issue -- especially since it would be nice to send an email from our own site, instead of needing to use a whitelisted server? Thanks!

• Is there a way to catch cmd.exe windows into tabs?

  - by user55542

  I use an editor that allows me to type in a command to run. In order to see the output without having to redirect it to a file, I precede the command with "cmd /k," which leaves an open cmd.exe window. So I'd like to find a way to move catch the call to cmd.exe and give it to an application that tabifies cmd.exe, a terminal emulator as it's called. The desired result would be similar to what happens in a tabbed editor, when that editor is to open some file, it does so in another tab, and not in another window. While in a given situation it may be easier to modify the command to redirect output to display in the editor itself, in general it would be more helpful if I could find a way to catch all such calls into one window.

• How do you interpret `strace` on an apache process returning `restart_syscall`?

  - by indiehacker

  We restart an apache server every day because RAM usage reaches its limit. Though of value See this serverfault answer, I dont think lowering the MaxClients in the apache configuration is a solution to the unknown root problem. Can you make sense out of the below data? Below is an extract of what $top with M returns: 20839 www-data 20 0 1008m 359m 22m S 4 4.8 1:52.61 apache2 20844 www-data 20 0 1008m 358m 22m S 1 4.8 1:51.85 apache2 20842 www-data 20 0 1008m 356m 22m S 1 4.8 1:54.60 apache2 20845 www-data 20 0 944m 353m 22m S 0 4.7 1:51.80 apache2 and then investigating a single process with $sudo strace -p 20839 returns only this one line, which is cryptic, for me: restart_syscall(<... resuming interrupted call ...> <unfinished ...> Any insights? Thanks.

• Clone drive in Windows

  - by ERJ

  I have two 2 TB external USB hard drives, call them HD1 and HD2. HD1 is USB 2, HD2 is USB 3. Each drive contains exactly one NTFS partition. I want to clone HD1 to HD2, because it's newer and much, much faster. What's the best way to do this? I don't want to do a copy-and-paste, I want to clone the whole partition. The new drive is actually a few bytes larger, so this should be possible? I don't have a second drive that can hold the image, so it would have to clone directly to the other disk (not to a file). How can I accomplish this on Windows 7? I know about Clonezilla but I would prefer not to have to boot from a CD or anything, as I don't have the capability to do that right now. I want to know if there's a way to do this while running Windows.

• Toolset agnostic build server and Silverlight projects

  - by Marko Apfel

  Problem Normally I try to have my continuous integration as most a possible toolset free to ensure that no local stuff could have an impact to my build. My Silverlight app references a special compile target in a folder outside my developer tree: <Import Project="$(MSBuildExtensionsPath32)\Microsoft\VisualStudio\v10.0\WebApplications\Microsoft.WebApplication.targets" /> So I copied the stuff from this folder to a local one and changed the call to this target in my csproj: <Import Project="..\..\..\tools\WebApplications\Microsoft.WebApplication.targets" /> And now Visual Studio Conversion Wizard welcomes my with this: Solution Regardless of which line I write – this conversion comes back again and again, if the line has another form than <Import Project="$(MSBuildExtensionsPath32)\Microsoft\VisualStudio\v10.0\WebApplications\Microsoft.WebApplication.targets" /> So it seems that there is no simple way to change this behaviour. Workaraound I must accept, that this line must be in the csproj and to run the build the toolset must be copied to the build server at the correct location. So go to your development machine where Visual Studio is installed and copy the folder “C:\Program Files (x86)\MSBuild\Microsoft\VisualStudio\v10.0\WebApplications” to your build server at the equivalent location.   Xmas wishes to Microsoft: Please provide technologies to let us developers bundle all needed stuff for a project in one developer tree. It should be possible that one checkout starts us up! No additional installations regardless whether it is a developing machine or dedicated build or continuous integration server. Silverlight is only one example, code analysis configurations could also be terrible and much more …
