• Connect iPad to windows 7 VPN

  - by Linuz

  My iPad keeps spitting out the error: "A connection could not be established to the PPP server." I am trying to connect it to a VPN I set up with Windows 7 as an incoming connection. On the iPad, I went into the VPN settings, added a new PPTP VPN with the following information Server: Windows 7 Computer's IP RSA SecurID: OFF Account: Account Username Password: Account Password Encryption Level: Auto Send All Traffic: ON Proxy: Off Now I know that it is making some connection to the Windows 7 Computer because whenever I intentionally put in the wrong VPN password on the iPad, it makes me put in the correct one before trying to connect again. All the ports are forwarded on my router for PPTP, and my Windows 7 Firewall is even off to try to get this to work. Any help would be greatly appreciated, thanks.

• Screenflick Audio option in MacBook Pro

  - by John

  When after I shut down my MacBook Pro by holding the power button for a few sec, (which I found is bad for the computer, so I will not do anymore) I found that my speaker doesn't play until I plug in and out earphone into the machine. When my speaker is not working like this, and when I am on a random webcam chatting site like chatroulette.com, they can hear the music playing on my iTunes when I choose Screenflick Audio option in the Mic setting. But when the Speaker is working back again, they don't hear the music playing even when I do Screenflick Audio mode. How can I make it work? Also, how do you make the chatting partner hear my music playing on my computer while I talk to them (not via my speaker, since it's bad quality).

• How can I retrieve data from a Western Digital Passport External Disk which is not getting recognized but getting shown as healthy in Device manager

  - by Rabimba Karanjai

  When I plug in this external harddisk It is not getting shown in the My Computer. But it gets shown perfectly well in the Device Manager When I go into the Computer Administrative panel and into the disk manager it asks me to initialize the disk Now when I try to initialize it, regardless of the method I try it shows me an error "Incorrect Function" As you can see windows tells me it is working properly. Is there anyway I can retrieve data from this?/access it? I have googled and it seems to be a frequent problem with WD drives. Anyone has any solutions on how I can get the data back?

• How are file permissions applied for shared drives?

  - by sleske

  I have two computers: A (running Windows Vista) B (running XP). I shared C: on computer A (as \\A\C ), and require a username (X) plus pw to access it. If I browse the the share \A\C on computer B, after entering username+pw I can access most folders, but one folder "\\A\C\F" gives me "permission denied". I looked at that folder's permissions on A, and it has full access permissons for all "Administrators". I use the account "A\X" to authenticate when accessing the share on A. X is a user account (on A) that is an "Administrator" according to Window's user management. Still, I cannot access this folder. If I explicitly add the "X" account to the accounts that may access folder F (under Properties / Security), I can access it without problems. I do not understand why I need to explicitly grant permission for X to get access to F. Is it not enough that X is an Administrator account?

• Accessing locally hosted webpage via public IP

  - by Mk12

  Sorry if this is in the wrong place.I don't really know anything about server-related things, but I'm really curious about this. On my mac I figured out how to make a simple web page viewable via the local ip address or computer name on the LAN, and also how to hook it up with a free hostname from dyndns.com. So the dyndns hostname points to something, how can I access it directly? Typing in the global ip address (of the router) doesn't work, but if it did, how would it know which computer to point to? There must be some way of directly accessing what dyndns hostname points to by typing in some number, right? Sorry I don't really understand how it works.

• is wisdom of what happens 'behind scenes' (in compiler, external DLLs etc.) important?

  - by I_Question_Things_Deeply

  I have been a computer-fanatic for almost a decade now. I've always loved and wondered how computers work, even from the purest, lowest hardware level to the very smallest pixel on the screen, and all the software around that. That seems to be my problem though ... as I try to write code (I'm pretty fluent at C++) I always sit there enormous amounts of time in front of a text-editor wondering how every line, statement, datum, function, etc. will correspond to every Assembly and machine instruction performed to do absolutely everything necessary for the kernel to allocate memory to run my compiled program, and all of the other hardware being used as well. For example ... I would write cout << "Before memory changed" << endl; and run the debugger to get the Assembly for this, and then try and reverse disassemble the Assembly to machine code based on my ISA, and then research every .dll, library file, linked library, linking process, linker source code of the program, the make file, the kernel I'm using's steps of processing this compilation, the hardware's part aside from the processor (e.g. video card, sound card, chipset, cache latency, byte-sized registers, calling convention use, DDR3 RAM and disk drive, filesystem functioning and so many other things). Am I going about programming wrong? I mean I feel I should know everything that goes on underneath English syntax on a computer program. But the problem is that the more I research every little thing the less I actually accomplish at all. I can never finish anything because of this mentality, yet I feel compelled to know everything... what should I do?

• Mysql refusing connection: a very special connection issue

  - by k to the z

  I have my programers remoting into a web server with windows rdp. This web server is the only machine that can access another mysql server in a secure zone. When I remote into the web server from my machine I am able to connect to the mysql server through the mysql workbench on the web server. However, when I try this same procedure from another person's computer I can get into the server via rdp. I just can't connect to mysql using the workbench. I have checked and re checked the credentials and connection information. They match. I've had other people check and re check the credentials. As far as mysql permissions are concerned this user is allowed to connect from any machine. Plus I'm remoting into the same web server. The only difference seems to be which computer is remoting into the webserver. wtf?

• I don't program in my spare time. Does that make me a bad developer?

  - by not-my-real-name

  A lot of blogs and advice on the web seem to suggest that in order to become a great developer, doing just your day job is not enough. For example, you should contribute to open source projects in your spare time, write smartphone apps, etc. In fact a lot of this advice seems to suggest that if you don't love programming enough to do it all day long then you're probably in the wrong career. That doesn't ring true with me. I enjoy my work, but when I come home from the office I'm not in the mood to jump straight back onto the computer and start coding away until bedtime. I only have a certain number of hours free time each day, and I'd rather spend them on other hobbies, seeing friends or going outside than in front of the computer. I do get a kick out of programming, and do hack around outside of work occasionally. I'm committed to my personal development and spend time reading tech blogs and books as a way to keep learning and becoming better. But that doesn't extend so far as to my wanting to use all my spare time for coding. Does this mean I'm not a 'true' software developer at heart? Is it possible to become a good software developer without doing extra outside your job? I'd be very interested to hear what you think.

• Autoplay for USB drive keeps popping up

  - by Adam Haile

  I have a Seagate external 2TB USB drive that when I leave it plugged in, the Autoplay dialog asking what to do with the drive pops up about once every 30-60 minutes. No matter how many times I tell it to go away, it keeps coming back. I have tried multiple power supplies, USB cables, and all the USB ports on my machine...but it keeps doing the same thing. Also, this does not happen with the same drive on a different computer. Could this be some power or configuration setting that is causing this? I'm running Windows 7 x64 (the computer it works on is x86)

• after power outage, monitor won't turn on

  - by J82

  I had a power outage in my apartment today during a Windows 7 SP1 update. I installed SP1 and it told me to restart so I did and that's when the power outage happened. After the power came back on, I started the computer and it looks like the computer is running normally but my monitor is not getting a signal. I am using a Wacom Cintiq 21UX. I tried unplugging all the cords and plugs in the power strip and turning it back on. I also tried a strange method I read in another thread of removing the power cord, holding the on button for 30 seconds, putting the power cord back in, and turning it on. Still no dice. How can I get my monitor to turn on? please help..

• Using command line to connect to a wireless network with an http login

  - by Shane

  I'm trying to connect to a wifi network where it hijacks all requests and redirects you to a page where you have to agree to a terms of use before it lets you connect to the actual outside world. This is a pretty common practice, and usually doesn't pose much of a problem. However, I've got a computer running Ubuntu 9.10 server with no windowing system. How can I use the command line to agree to the terms of use? I don't have internet access on the computer to download packages via apt-get or anything like that. Sure, I can think of any number of workarounds, but I suspect there's an easy way to use wget or curl or something. Basically, I need a command line solution for sending an HTTP POST request essentially clicking on a button. For future reference, it'd be helpful to know how to send a POST request with, say, a username and password if I ever find myself in that situation in another hotel or airport.

• Graphics hardware warning when updating to 14.04

  - by pacomet

  As I use Ubuntu at work I just update only LTS versions but now I'm not sure if I can/should. As my computer is now ten years old I would change if was mine but as it is owned by my employer I have to work with it. It's not a bad one, it runs fine (this was not true when still had Windows on it ;-). When updating to 14.04, it warns about possible bad/slow performance with Unity 3D so I stop updating as I am at work, not my own computer. As I understand from http://askubuntu.com/a/438958/25305 Nvidia Geforce FX 5500 graphics card is still supported in 14.04. Now, in 12.04, I have driver version 173 and unity 2d runs fine for me. output of /usr/lib/nux/unity_support_test -p OpenGL vendor string: NVIDIA Corporation OpenGL renderer string: GeForce FX 5500/AGP/SSE2 OpenGL version string: 2.1.2 NVIDIA 173.14.39 Not software rendered: yes Not blacklisted: no GLX fbconfig: yes GLX texture from pixmap: yes GL npot or rect textures: yes GL vertex program: yes GL fragment program: yes GL vertex buffer object: yes GL framebuffer object: yes GL version is 1.4+: yes Unity 3D supported: no Should I update? Is it better to stay with 12.04? Thanks

• Cannot fix induced 0x7b error on XP

  - by Malfist

  I'm writing a tool that will automagically fix the STOP 0x7B error that occurs when windows cannot access the hard drive due to driver issues (usually). I've wrote a tool that does everything the Knowledge Base article says to do. But it's not working. I'm inducing the issue by changing the bios SATA controller to AHCI, then moving it to another computer and updating it's registry. When I move it back to the other computer, nothing new happens. Can someone tell me what more I need to do?

• Possible to change the order of the shortcut locations in windows explorer

  - by Codezilla

  When you open a new explorer window by default it loads from the starting position "Computer" which shows your drives, etc. This is all well and good except when explorer loads it bumps the scroll bar down so that half the favorites are cut off. I can scroll up to get to the ones I want but that gets really old doing that 50 times a day. I do clean out my favorites frequently but more are added all the time and used. In trying to come up with a fix for this problem I thought maybe it would be possible to move the link to "Computer" to be at the very top and the "Favorites" area directly under that but I can't figure out a way to do that. Anyone have an idea? Or maybe another solution I haven't thought of?

• Why does my general frame rate slow down to 40fps randomly?

  - by Joshua

  This has been bugging me for a while. Every once in a while, I find my computer to be sort of laggy and I thought it was because it was busy or something. However, I recently noticed that it wasn't any performance issue...I thought my computer was laggy because the frame rate slowed from 75fps right down to ~40 fps and caused very visible tearing. This is not rare. It happens many, many times a day. I have no idea what is happening...I have an AMD 5670 on Windows 7 32-bit by the way, and I've heard bad things about AMD's driver support. Could this be the problem? P.S. The frame rate slowdown is not just for games (I rarely play games, and have not played games in the time since I noticed this problem), it seems it's an issue for the entirety of Windows. I first noticed the tearing when I was moving around tabs in Google Chrome.

• Ubuntu won't log in after update

  - by Dave M G

  I just updated Ubuntu about 15 minutes ago on my desktop which is running 12.04. Within the set of updates, there were some kernel upgrades. It didn't say I needed to reboot after the update was finished, but I thought I would anyway. The computer successfully rebooted up to the login screen. However, after entering my password, the screen goes black for a moment, then it comes back to the login screen. I tried the suggestions in this question, but unfortunately they didn't help. In the accepted answer, the questioner vaguely says it was a "Unity problem". I'm using Gnome-classic with full Compiz effects. I tried uninstalling and reinstalling Compiz, but that didn't fix anything. So... I can't use my desktop computer until this is fixed. I hope there is some help soon. I've uploaded the output of cat /var/log/Xorg.0.log to Pastebin. A temporary solution of changing to gdm instead of lightdm was found with help in the chat room.

• Did C++11 address concerns passing std lib objects between dynamic/shared library boundaries? (ie dlls and so)?

  - by Doug T.

  One of my major complaints about C++ is how hard in practice it is to pass std library objects outside of dynamic library (ie dll/so) boundaries. The std library is often header-only. Which is great for doing some awesome optimizations. However, for dll's, they are often built with different compiler settings that may impact the internal structure/code of a std library containers. For example, in MSVC one dll may build with iterator debugging on while another builds with it off. These two dlls may run into issues passing std containers around. If I expose std::string in my interface, I can't guarantee the code the client is using for std::string is an exact match of my library's std::string. This leads to hard to debug problems, headaches, etc. You either rigidly control the compiler settings in your organization to prevent these issues or you use a simpler C interface that won't have these problems. Or specify to your clients the expected compiler settings they should use (which sucks if another library specifies other compiler settings). My question is whether or not C++11 tried to do anything to solve these issues?

• Changing Word mail merge data source locations in bulk?

  - by Daft Viking

  I've just moved a number of Word mail merge files, and a number of Excel spreadsheets that are the data sources for the mail merges, from a Windows XP computer to a Windows 7 computer, and now all the paths for the merge sources are incorrect (used to be c:\documents and settings\user\my documents.... now c:\users\documents....). While I can correct the path of the data source in each file individually, I was hoping that there would be some way of updating the files in bulk, as there are a relatively large number of them. Word 2007 is what is being used, but the documents are all in the previous DOC format (not DOCX).

• PCs with Wired Connection Keep Losing Internet Connectivity

  - by user717452

  I have a U-verse ATT DSL Internet at our church building. Recently, any computer that is plugged into the network via Ethernet keeps losing its internet connectivity. The setup is from the Modem to a Netgear Wireless Router, and from the router to 3 different computers. None of the laptops that use Wifi ever lose internet, just the wired ones, and I end up having to do ipconfig /release and /renew every day to get it back. One computer has Windows 7 and one has Windows XP. Any ideas as to what is going on with our network?

• Crap, hard disk failure. Can I recover my "move"d folders?

  - by Doug

  I am in the process of moving all my files from an old laptop to new one. I just moved 11gb of data from my old laptop to a hard drive (external) and then upon moving it out to the new hard drive, the hard drive is getting a CRC (Data Error (Cyclic Redundancy Check). Now I am looking for a solution to recover the files that I moved on my old laptop (not the external). I understand they they are just marked for potential overwriting to free up space. I was getting ready to test out GetDataBack, but it says to install it on a healthy windows and use the recover-needed drive as an external. However, I don't want to turn off my computer without first getting the okay since it is in a "moved" state. Please help! What can I do to recover the Moved files. I haven't touched the computer since it has been moved. What can I use to recover them?

• Where can I get a splitter to connect a device with a single 3.5 mm plug into the audio input/output jacks on my laptop?

  - by XinJeisan

  I recently bought the :Hype Retro Handset for Mobile Phone" -- its just a device that looks like a handset to use when chatting on a computer or mobile phone that plugs into the phone/computer with a single 3.5 mm plug. I was hoping to use it on my windows 7 Toshiba laptop. I can hear audio fine through the handset but what I'm saying is not being picked up on the handset. On the box it says "some phones and computers may need additional adapters," so I'm hoping it is possible to get a splitter or something for this to work properly. I did email the parent company (http://dglusa.com/) but I haven't heard from them, and, looking over their website, I doubt I will. I also went to the local radio shack, and the guy said I needed a splitter, but he didn't know where to get one. I can find the kind of splitter I think I need online, but I'm unsure whether they are just for output or can also do input/output.

• windows printer spool gets stuck with file at 64kb from linux and mac

  - by Juan Diego

  Hi I have two printers one on a file server with windows 2003, and other with windows XP. The thing is that when i try to print from my machine, my file stays in queue for ever, it says 64kb out of whatever the file i send. I have seen similar problems with some machines that run on Mac OS X. The windows machines apparently have no problems printing. They are not connect through active directory, just the network. In the past I have seen people install non microsoft windows Printer server on windows, i dont remember the name of any of the programs. I have being googling a lot and have not found anything to replace the microsoft print spooler service, maybe i am mistaken. Everyday I have to restart the print spooler service i even created a bat file for it. I am out of ideas here.

• Cannot copy anything onto WD Elements 1TB External USB HDD

  - by Aashish Vaghela

  I have a Western Digital 1023 Elements 1TB External USB HDD. Recently, it has started an unusual problem. I cannot copy any file of any size on to that 1TB hard-drive, eventhough it has more than 400 GB free (out of 931GB actual size). I tried copying movies from one friends laptop, which did not work. I also tried another desktop to copy some study material e-books (in PDF), which also did not work. I get same CRC error when I try to copy anything from a computer's hard-drive onto this WD 1TB hard-drive. Vice-versa it's working. I mean, I can copy any file from the USB HDD onto local machine's HDD on any computer. It's like one-way traffic. This HDD is only 1 year old. What are my options ? Any suggestions ? Regards, Aashish.V

• Odd FTP ASCII/BINARY transfer behavior after migrating to a new server

  - by Incognita Mundi

  I recently got a dedicated server and after migration to the new machine I started noticing problems with file transfers. My FTP client, despite being set to auto, keeps uploading php files in binary mode and the content of those files is messed up. Since I mostly upload files of different kinds it would be annoying to change from binary to ASCII every single time, beside, I never had such problems. What could be the cause of this behavior? My dedicated server runs CENTOS 6.4 and the ftp server is Pure-FTPd. I tried different FTP clients and they all have the same problem so I assume is soem misconfiguration on the server side. Thanks

• Dropbox fails to install on Ubuntu 13.10

  - by Fraxav

  I've done some research and it seems Dropbox has some problems with the status icon on Ubuntu 13.10, but I can't even manage to install it. The very first time, I installed nautilus-dropbox from the app center on a freshly installed Saucy, but I couldn't see the status icon and clicking the app icon wouldn't help, so I uninstalled and rebooted. The second and third time, the app just freezed at about 75% while installing from app manager, so I had to shut down the computer and uninstall. Next I tried to install dropbox from the .deb (from website): it installed (the launcher?) from app manager, then the dialog prompted me to start dropbox and finally to download the official daemon, but the download freezed at 0% and made everything else buggy/laggy (probably also because I restarted nautilus, as required, at that point). After a purge and clean from terminal, some icons and this file (which I suspect is somehow responsible, but of course is locked) are still present on my computer. Can anyone help me figure how how to install it? How could I remove that configuration file so I can give it a last shot?
