• Synergy Locks up w7 when Visual Studio is debugging

  - by EdK

  I love synergy but as a developer this is driving me crazy. I use Synergy to go through two x64 Windows 7 machines (with all flavors of Visual studio from 2003 to 2010 professional) and an MacOS 10.6? desktop and most of the time it works flawlessly. However, if I happen to be in the middle of a transition from one windows 7 machine to the other (it's never happened to the mac but I don't flip to it that often) when Visual Studio hits a breakpoint, the mouse and keyboard both completely lock up and the only way I can seem to do anything is to physically unplug the mouse and keyboard and plug them back in. Unfortunately I have to crawl under my desk to do that, so you can see where it'd be annoying. Anybody have any idea how I can get around this? I did note that it was much more frequent with the previous version I had of synergy+ before I upgraded/sidegraded to the current version of synergy. But it's still happening. Thanks alot,

• Data transfer is extrem slow after partitioning extern usb drive

  - by user125912

  I bought an extern usb 3.0 drive with 500 gb capacity. OS is Windows 7. I use it with an usb 2.0 slot, no prob. Initially I used it without making several partitions and it was fast as hell. Then I had the great idea to make partitions, one for programs, one for data and one for backup. I chose the free EASEUS Partition Master 9.1.1. and ended up with these partitions: F:Apps, primary, NTFS, 100gb H:Data, logic, NTFS, 250gb B:Backup, logic, NTFS, 150gb THE PROBLEM: When I copy files from C: to F: I get a transfer rate of about 100 KB/S ! When I copy files from C: to H: I get a transfer rate of about 4 MB/S ! thats all muuuch to slow, slower then before. What can I do to speed the shit up? Thanks in advance!

• Make Ms Word activate window of file if it is already open when I double click the file's icon?

  - by barlop

  When I try to open a word document that is already open, I want it to just activate the window where the file is open. How can I do that? sometimes it takes time to check if an ms word document is already open, I don't to have to have to check through a bunch of open word documents to see if it's in there or not, I just want to double click the icon of a word document, and if it's open then go to it, if not then open it. With the doc/docx or shortcut to the doc/docx , I have some files where when I double click , it activates it when already open. I have other files where double clicking will bring up a "file in use" dialog box. I can't find what is the cause. I want it to always activate the window rather than reopen it. update- maybe that is default behaviour to activate when already open, and after a crash I had that stopped. i'll try deleting the working files and starting ms word again, idea from here

• Why does everybody have the same MAC address as me?

  - by iblue

  I just bought some consumer-grade McCheap PCI-E NICs (and this was a bad idea). They both have the same MAC address. When I google it, it seems like every card of that company has the same address: 00:50:43:00:45:3e. Shouldn't they be unique? According to lspci it's a Marvell Technology Group Ltd. 88E8053 PCI-E Gigabit Ethernet Controller (rev 20). Is there a way to permanently flash a new address?

• macports apache,php,db, how do I test on another device?

  - by brokenindexfinger

  My supervisor suggests using macports to install/manage different versions of apache and php, as well as both mysql and posgres databases. The idea is that we need to test our platform on different versions of each. So far I've just been using the default apache installation on osx lion, and the default postgres installation. My question is this: once I turn Web Sharing off, and proceed with a custom apache2 setup based in /opt/local/, how do I broadcast my machine's IP to other devices, for testing? With Web Sharing, I can get my machine's IP and use that to test with an iPad and iPhone. Will that still be the case, and if so, how do I do it?

• Operating system not found after downloading skin pack

  - by 8BitSensei

  My brother has downloaded a executable file from Skin Pack — I believe it was the Mountain Lion IO6 skin pack. He's using an Acer Aspire 553G. And now his operating system won't start (Windows 7). It gets to the BIOS and then goes to load up the OS but the screen goes blank and it just goes back to the BIOS over and over again. He decided to play with the bootup settings and tried different options and got the error message "Operating System not found." Does anyone have any idea how to solve this?

• What precaution should I take to hire online freelancer designers? [on hold]

  - by tomDev

  For quite some time my company is super busy with our apps, and a few days ago someone contacted me by email offering his services to help me as a graphic designer. He has a fair price, a flickr portfolio (with great stuff but not popular at all), same on Twitter. I was really considering in hiring him for some specific service, but the question is... what precaution should I take when hiring someone I have no idea who is? I can't even be sure I have his real name and his real country. How do I make a contract? How do I pay? How do I know he will not sue us after the graphics reach the App Store asking for more money? And of course, how do I know he will actually do the service and not steal from some stock service? Am I a bit paranoiac or is this a common deal with graphics designers? PS: if someone asks I can provide his flickr, but I think this is a general question and not specific for this designer.

• Fix X11 forwarding on OSX

  - by Such

  I am looking for a way to fix/debug a X11 forwarding session on OSX. Here is my situation: From my mac I connect to a Ubuntu workstation with ssh -X (tried ssh -Y as well). X11 forwarding works perfectly with firefox for instance, X11/Quartz is started automatically on OSX and firefox is displayed. X11 forwarding does not work with bat (Bacula graphical console): X11 is started but no window is displayed. There are no errors (/private/var/log/system.log). When I try doing the same from another Ubuntu workstation, it works perfectly for both firefox and bat. I guess the problem is on OSX side then. I tried switching some options in X11 but nothing works. Would you have any idea on how to move forward? Thanks!

• Corrupted files, hard drive test?

  - by all-R

  Hi guys, I'm currently on a macbook with a 1TB external hard drive connected trough a USB hub wich is connected on my macbook. The problem is, my disk, wich is partitioned in 2 (one HFS+ and one NTFS) keeps getting corrupted, recently it was my HFS+ partition, I could not repair it using the Apple's Disk utility, but was able to backup my files. Is it synonym that my hard drive is failing? Is it because of my USB hub? I also keep all my iTunes library on my external HD (HFS+ partition), and did a lot of transfer lately, adding files, removing etc. the last time, my partition got corrupted after a lot of deleted items. If anybody has an idea of what to check first, what could cause the problem, I would appreciate it :) Thanks!

Who have an idea who deleted my older backups? Thank you!

• Joomla in Windows is catching my access to a Virtual Directory where I placed my MVC application

  - by Romias

  In our windows hosting we use the root (wwwroot) folder to host a JOOMLA website as public website. This is running IIS 7. Then, we created a virtual directory called "App" to host there a ASP.NET MVC4 application. When I enter www.mydomain.com it shows the joomla website correctly. When I enter www.mydomain.com/App/ it somehow access my MVC app... as I see the URL changing to www.mydomain.com/App/Account/LogOn?ReturnUrl=%2fApp%2f BUT shows a 404 Joomla error as if it were looking that URL in Joomla. BTW, the hosting has 2 ASP.NET IIS Setup options: 4.0 Classic and 4.0 integrated. Using the Integrated one... it displays a blank page... using the classic one shows the 404 Joomla page. Any idea where to look for this?

• Forward Request to Multiple Servers

  - by cactuarz

  We have 2 servers. One is old server and another is the new one. Currently we about doing a migration because the old server is not capable enough to handle everyday requests. The specs are: Old server Ubuntu 10.04 Nginx as Reverse Proxy Apache WSGI Python/Django New Server Ubuntu 10.04 Nginx Gunicorn Python/Django Celery+Redis Our manager asked us to research if the old server can perform multiple forwarding to all incoming request, for example, set Nginx of old server to forward all request to both old and new server. The purpose is to perform unit testing to new server using old server as comparer, see if the new server is ready to take over the role. Please help, if there is an idea, or must install some engine, or what we do is impossible. Many thanks.

• Motherboard with embedded hdmi problems with Windows 8 Consumer Preview (64bit)

  - by duluca

  I'm specifically referring to GIGABYTE GA-E7AUM-DS2H LGA 775 NVIDIA GeForce 9400 HDMI Micro ATX with a Core 2 Duo chip. This computer is connected to a Sharp Aquous TV using HDMI. It all worked fine with Windows 7 64 bit. In Device Manager I see GeForce 9400 and have installed the latest NVidia drivers (295.73 WHQL). However, when I click on the change the screen resolution to 1920x1080, I see that Windows 8 thinks that it's using some other graphics card with Microsoft Basic Display Driver. This was made clear, when I tried to launch the NVidia tools and it claimed that the current monitor (in this case my TV) wasn't attached to the GeForce 9400 card. In Device Manager, there's a "Coprocessor" and "Unknown device" without drivers, but I've no idea what they are. I've run the original CD that the motherboard came with no success. Any ideas?

• Trac permission denied for SVN repo

  - by plesatejvlk

  I'm running Apache2,SVN & Trac on OpenSUSE. SVN works like a charm. I've initialized trac environment for one of my SVN repositories for trac to show source code in it's repo browser and I set the repository up in the Trac web admin. I also ran the trac-admin resync for that repo without problems. Trouble is when I open the Trac repo browser I get: "can't open file: /srv/svn/repos/myrepo/format, access denied)" error. I checked the permissions and: apache runs as wwwrun tracd runs as wwwrun the whole subtree /srv/svn/... belongs to svn group and the group has rw perms all the way down to the "format" file wwwrun is in the svn group I also did the perms check: $ sudo -u wwwrun cat /srv/svn/repos/myrepo/format and got it printed out without trouble. So in my opinion there shoud not be any permission conflict. Any idea what else to check? Thanks in advance!

• SSL on Apache seems to significantly affect WebDAV performace

  - by takesides

  I'm using Apache 2.2 running on Windows Server 2008 R2 as a WebDAV server for clients to upload large media files (roughly 100-2000MB). I am finding that when I have SSL enabled (openSSL 0.9.8o) and use HTTPS for the uploads the throughput is around 13Mbps but when I disable it and just use HTTP I get around 80Mbps. I can't understand why this is happening as my understanding was that the heavy SSL work was done at the beginning of the connection. Does anyone have any idea why the performance is so drastically affected by enabling SSL? Cheers.

• How can I use an object pool for optimization in AndEngine?

  - by coder_For_Life22

  I have read up on a tutorial that allows you to reuse sprites that are re-added to the scene such as bullets from a gun or any other objects using an ObjectPool. In my game i have a variation of sprites about 6 all together with different textures. This is how the object pool is set up with its own class extending Java's GenericPool class public class BulletPool extends GenericPool<BulletSprite> { private TextureRegion mTextureRegion; public BulletPool(TextureRegion pTextureRegion) { if (pTextureRegion == null) { // Need to be able to create a Sprite so the Pool needs to have a TextureRegion throw new IllegalArgumentException("The texture region must not be NULL"); } mTextureRegion = pTextureRegion; } /** * Called when a Bullet is required but there isn't one in the pool */ @Override protected BulletSprite onAllocatePoolItem() { return new BulletSprite(mTextureRegion); } /** * Called when a Bullet is sent to the pool */ @Override protected void onHandleRecycleItem(final BulletSprite pBullet) { pBullet.setIgnoreUpdate(true); pBullet.setVisible(false); } /** * Called just before a Bullet is returned to the caller, this is where you write your initialize code * i.e. set location, rotation, etc. */ @Override protected void onHandleObtainItem(final BulletSprite pBullet) { pBullet.reset(); } } As you see here it takes a TextureRegion parameter. The only problem i am facing with this is that i need to have 6 different sprites recycled and reused in the ObjectPool. This ObjectPool is set up to only use one TextureRegion. Any idea's or suggestions on how to do this?

• Deployed Web Application Requests for User Name and Password

  - by user43175

  Deployed Web Application Requests for User Name and Password I recently deployed a .NET web application into the server. Authentication mode is set to Windows (since the application is accessible only to Intranet users. Testing some machines, the application loads up properly. For some machines, a logon dialog window appears asking for User Name or Password. These dialog windows are those that you also normally see when you are trying to log into a Windows domain. Any idea why this happens randomly? Thanks.

• Hylafax with serial over IP modem

  - by zero_r

  I'm looking into virtualizing a Hylafax server which currently runs on a dedicated hardware running CentOS with a Divalogic card. The main issue obviously is, how to connect the modem to the VM. There are serial over IP devices available at digi.com. Maybe there are others? Regarding digi.com devices, as far as I understood one can install the RealPort software and then have a /dev/ttySx device presented to the Linux server. This device then can be used as serial connection to the modem. Does someone have such a configuration in place? Or does someone have another idea to virtualize a Hylafax server (outbound faxes only). Thank you in advance

• after upgrade from 10.04 to 12.04 cannot boot with linux 3.2.0-24-generic-pae

  - by Ricardo

  After upgrade from 10.04 to 12.04, I cannot boot with linux 3.2.0-24-generic-pae: process gets frozen in a xubuntu initialization screen (I had qimo installed). If I try the recovery mode (with the same Linux version), booting freezes after this message: Begin: Mounting root file system. If in grub menu I choose Previous Linux versions, I can boot using Linux 2.6.32-41-generic-pae. But once logged in, some things don't seem to work (apt-get update fails, update manager fails, HID menu does not provide suggestions...) (to be honest, I have no idea whether this is part of the bigger issue) Reading in Ask Ubuntu through apparently similar problems, I decided to follow some advices: got boot-repair and run it. The problem remains & I got this report. I also run as root in terminal $ sudo update-initramfs -u and this is what I got: update-initramfs: Generating /boot/initrd.img-3.2.0-24-generic-pae cryptsetup: WARNING: failed to detect canonical device of /dev/sda1 cryptsetup: WARNING: could not determine root device from /etc/fstab /tmp/mkinitramfs_EIDlHy/scripts/classmate-bottom/45xconfig: 9: .: Can't open /scripts/casper-functions What else? My pc is Intel® Core™ i7 CPU 870 @ 2.93GHz × 8, graphs is GeForce 8400 GS/PCIe/SSE2, memory is 7,8 GiB. I have two questions: Is this a bug in the newest kernel I should report? Is there anything I can do appart from a fresh install?

• What is the most concise, unambiguous syntax for operator associated methods (for overloading etc.) that doesn't pollute the namespace?

  - by Doug Treadwell

  Python tends to add double underscores before its built-in or overloadable operator methods, like __add(), whereas C++ requires declaring overloaded operators as operator + (Thing& thing) { /* code */ } for example. Personally I like the operator syntax because it seems to be more explicit and keeps these operator overloading methods separated from other methods without introducing weird prefix notation. What are your thoughts? Also, what about the case of built-in methods that are needed for the programming language to work properly? Is name mangling (like adding __ prefix or sys or something) the best solution here? What do you think about having another type of method declaration, like ... "system method" for lack of creativity at the moment. So there would be two kinds of declarations: int method_name() { ... } system int method_name() { ... } ... and the call would need to be different to distinguish between them. obj.method_name(); vs obj:method_name(); perhaps, assuming a language where : can be unambiguously used in this situation. obj.method_name() vs obj.(system method_name)() Sure, the latter is ugly, but the idea is to make the common case simple and system stuff should be kept out of the way. Maybe the Objective-C notation of method calls? [obj method_name]? Are there more alternatives? Please make suggestions.

• How to know the level of a symlink in linux?

  - by ???

  For example, if a symlink a -> b b -> c c -> d say, the symlink level of a is 3. Then, is there any utility to get this info? And, also I want to get the expansion detail of a symlink, which will show me something like: 1. /abc/xyz is expanded to /abc/xy/z (lrwx--x--x root root) 2. /abc/xy/z is expanded to /abc/xy-1.3.2/z (lrwx--x--x root root) 3. /abc/xy-1.3.2/z is expanded to /abc/xy-1.3.2/z-4.6 (lrwx--x--x root root) 4. /abc/xy-1.3.2/z-4.6 is expanded to /storage/121/43/z_4_6 (lrwx--x--x root root) 5. /storage/121/43/z_4_6 is expanded to /media/kitty_3135/43/z_4_6 (lrwx--x--x root root) So I can diagnostic with the symlinks. Any idea?

• Audio Line-In on Ubuntu/Linux Mint

  - by hahuang65

  I'm currently on Windows, and want to switch to Linux, but some hardware issues are preventing me. Mainly, I have a sound card that supports Line-In. On Windows, anything I plug into the line-in gets outputted to the speakers. However, when I installed Linux, because there is not a control application that comes with the driver, I have no idea how to set this up. I tried going to the sound settings and it doesn't seem to be there. I also want to configure it for 2.1 sound, and do not know how to do that... Anyone here done it before? Thanks in advance for the help!

• how to override ckeditor events [migrated]

  - by joe

  I am new to ckeditor, I have hard time figuring this issue out. due to my html design; if I try to use the link editor dialog while my ckeditor is maximized, it just doesn't show up, I understand that ckeditor is the top most object in my html page and the link dialog comes underneath it. if now I bring ckeditor to its normal state I will be able to see and use the link dialog. my idea is to slightly override the link button click event as follows: if the editor is in full screen mode, bring it back to the normal state. and keep a flag somewhere so that when I close the link dialog, I can decide whether to bring back the ckeditor to a maximized mode again. now this is easy logic except that I do not know how to override the click event of the link button and keep it work as expected. here's what I have: $().ready(function () { var editor = $('#txa').ckeditor(); CKEDITOR.plugins.registered['link']= { init : function( editor ) { var command = editor.addCommand( 'link', { modes : { wysiwyg:1, source:1 }, exec : function( editor ) { if(editor.commands.maximize.state == 1 ){ alert("maximized"); //....here bring back the editor to UN-maximized state and let the link button event click do the default behavior } else { alert("normal state"); } //2 is normal state //1 is maximized } } ); editor.ui.addButton( 'link',{label : 'YOUR LABEL',command : 'link'}); } } }); html part to make the exemple work: <div> <textarea id="txa"> </textarea> </div> TO BE SHORT: http://jsfiddle.net/Q43QP/ if the editor is maximized, bring it to normal state then show the link dialog.

• What is the cost of running a desktop machine at home?

  - by vinc

  How much does it (roughly) cost to leave my personal home computer running 24/7 for a year? I'm not doing anything unusual; I run a webserver for myself, surf the web, write some code. I don't have any specific specs. So for example there might be the cost of electricity, internet connection, and possibly some other factors that I've overlooked. I'm trying to decide whether it would be a good idea to turn off my computer when I'm asleep and not using it. Is the cost negligible, maybe 1 USD per day, something in between or more?

• Is there a (free or commercial) print server which print PDFs from networks?

  - by Eonil

  I'm working in office which uses Windows server for printing. Because our printer supports only Windows driver. But here are Mac OS X also which requires network printing... I'm sure there is no driver of the printer for Mac. So I figured out an idea to do this. On the Mac, a virtual printer driver generates and sends PDF file to print server. Print server, prints PDF files with it's local printer. Is there a solution can do this? (free or commercial)
