  • How do you change your Airport or Ethernet MAC address in Mac OS X 10.6?

    - by Dave Gallagher
    I have a MacBook Pro and would like to set a custom MAC address for either my Airport WiFi card, or Ethernet port. In older versions of Mac OS X, you could do it like this: $ sudo ifconfig en0 ether 00:11:22:33:44:55 // Ethernet $ sudo ifconfig en1 lladdr AA:BB:CC:DD:EE:FF // Airport For it to work on Airport, you'd have to power it on (e.g. $ sudo ifconfig en1 up), ensure it's not connected to any wireless network, and execute the command. I'm aware such a change won't propagate across reboots. Unfortunately, this doesn't work on Mac OS X 10.6.6 anymore. Apple appears to have removed the functionality (the command fails silently). Does anyone have any idea how to do it? Thanks for any help you can offer! :)

  • Does HDMI cable "quality" actually affect transmission?

    - by TheDeeno
    I really don't want to pay a ridiculous price for a "name brand" HDMI cable if it doesn't really do anything for me. I'm just curious: now that most transmission is digital (packetized) is there such a thing as a "quality" cable? I suspect that if the cable works at all, I'm safe saying I have a quality connection. I just want to double check. Some of these reviewers complain that generic cables "create noise, lack bandwidth, can't handle X, etc". I'm skeptical of these reviews. If the logic for HDMI cables and quality can be applied to cables in general, please elaborate on that as well.

  • Windows 8 not accepting password for a while

    - by soandos
    I recently upgraded from windows 8 Consumer Preview to Windows 8 Pro (RTM through dreamspark premium), and have the following issue: When I attempt to log in after a restart, it often takes a while (~3 minutes) for the computer to accept the password (Each try goes relatively quickly, a few seconds at most before telling me I have an incorrect password). I changed the password, and this issue is unresolved (the old password came with the upgrade). What could be doing this?

  • Pandoc: Output two sumation signs in equal height in Word 2010

    - by Andy
    I need to output some complex equations in Word 2010 (docx). To do so I write most of the equations in tex and use pandoc to translate them as Word formulas. However I have a problem with the following tex equation: \sum_{m=1}^\infty\sum_{n=1}^\infty In Word the resulting two summation signs are not of the same size but the latter is smaler than the first one. Is there any workaround to solve this? I would deeply appreciate any help. Thank you Andy

  • Control mouse with keyboard in Ubuntu

    - by WishCow
    I'm looking for a program that I can use to control the mouse from the keyboard. I think a video can explain it much better that I could, so please check out Mouser from lifehacker.com: http://lifehacker.com/212816/hack-attack-operate-your-mouse-with-your-keyboard Unfortunately, it's only for Windows, but something this would be the perfect solution. I found a lot of help on mapping keys to programs, but nothing about mapping keys to mouse control.

  • How to install RMagick RubyGem on Mac OS X 10.6 Snow Leopard?

  • Myvidoop error when trying to log in

    - by paul-werner.mp
    Recently I have not been able to get into my myvidoop username. It won't even bring up the pictures and asks to send the access code to one of my email addresses. I have seen this message before and there was no error previously but now it will not send the access code. I've tried accessing the site through firefox and through IE but I get the same thing (whether I went through the add on to get to the site or just typed in the website). I just want to know if I possibly have something that could be blocking it from sending this out. I use the free version of Avira for protection, run Ad Muncher (but I've also tried to get this access code with Ad Muncher closed), and have Ad Block Pro plugin (but like I've said before, the same thing happens in IE). I know it uses Java to send this access code out and I've even updated Java but still cannot get it to send it to me.

  • how to properly set environment variables

    - by avorum
    I've recently started using Windows (having used Ubuntu up until now) and I find myself unable to properly set environment variables. Whenever I set them they don't seem to work. I've been going to Start-Edit Environment Variables for your Account and editing the PATH value in the upper half of the GUI. Here's what I've got so far. ;C:\Chocolatey\bin;C:\tools\mysql\current\bin;C:\Program Files (x86)\Git\bin;C:\Program Files\MySQL\MySQL Server 5.6\bin\;C:\Python33\Scripts; These are each the parent directories of the executables I'd like to be able to run by name from CMD, but mysql, git, and pip aren't being recognized. Am I doing something wrong syntactically or at a general understanding level? I'd like to be able to run these commands without having to specify the full path to the executables every time. EDIT: The full PATH extracted from CMD PATH=C:\Python33\;C:\Program Files (x86)\NVIDIA Corporation\PhysX\Common;C:\Program Files (x86)\AMD APP\bin\x86_64;C:\Program Files (x86)\AMD APP\bin\x86;C:\Program Files\Common Files\Microsoft Shared\Windows Live;C:\Program Files (x86)\Common Files\Microsoft Shared\Windows Live;C:\Windows\system32;C:\Windows;C:\Windows\System32\Wbem;C:\Windows\System32\WindowsPowerShell\v1.0\;C:\Program Files (x86)\GTK2-Runtime\bin;C:\Program Files\WIDCOMM\Bluetooth Software\;C:\Program Files\WIDCOMM\Bluetooth Software\syswow64;C:\Program Files (x86)\ATI Technologies\ATI.ACE\Core-Static;C:\Program Files (x86)\Microsoft ASP.NET\ASP.NET Web Pages\v1.0\;C:\Program Files\Microsoft SQL Server\110\Tools\Binn\;C:\Program Files (x86)\QuickTime\QTSystem\;C:\Program Files (x86)\Common Files\Acronis\SnapAPI\;C:\Program Files (x86)\Java\jre7\bin;C:\Program Files (x86)\Windows Kits\8.1\Windows Performance Toolkit\;C:\Program Files (x86)\Microsoft SDKs\TypeScript\;C:\Program Files (x86)\MySQL\MySQL Utilities 1.3.4\; ;C:\Chocolatey\bin;C:\tools\mysql\current\bin I'm being forced to use Windows by my work environment, I don't enjoy the state of affairs.

  • Thin client - cloud machine - to run via iPad, iPhone, most Androids etc

    - by Carl Lindberg
    I'm tired of having a laptop macbook that breaks down or having files that I need to sync via dropbox etc all the time via the machines to different OS installations. It sucks. I want a thin client where I can login on any machine - my iPhone, PC desktop, iPad etc to one running machine. I would like to replace a modernly powerful desktop iMac with a thin client running via my iPad. I will connect the iPad with a keyboard/mouse too so you get the idea. But I want to be able to use some of the Android phones as well (I guess most Android phones today has a good enough performance/resolution etc to run a thin client). Of course it has to be able to have input/output in sound. Printing can be solved by PDF/emailing etc - so no direct communication to the printer ports to USB etc is necessary. Is there such a service today? It should cost somewhere under something like $40/ month. I will run stuff like CPU heavy duty ableton for music production, xCode for making iOS apps, some games etc. And on the thin client also run virtual machines. VM of Ubuntu and Windows.

  • Force view text file instead of download in Firefox?

    - by davr
    Often times I'll click on a random link to a .sh or .py or .cpp or ... file in Firefox, and all I want is to view the code. I don't have a Firefox handler set up for every text file extension under the sun, and I don't want to have to. Is there an easy way to force Firefox to view the file as text instead of trying to save (or open in external app)?

  • Is there a 64-bit Windows 7 driver for a Logitech Wingman Formula Force wheel?

    - by Bob Cross
    I've used my Logitech Wingman Formula Force wheel for more years than I can remember (I definitely had it back when I was playing Viper Racing, though). Sadly, Logitech does not appear to support the wheel in any capacity, even as an analog input device. At this point, I'm looking for any sort of driver that will take input from the device. I don't care at all about the force feedback but, if it were available, I'd be happy to take it. The target operating system is Windows 7 64-bit. EDIT: Just in case I'm not clear above: I know where the standard driver download sites are and have tried them out. The problem is that Logitech has officially end-of-lifed this wheel so their latest software specifically does not support it. Sadly, their older software that does support it is 32-bit only so I'm out of luck on that front.

  • Sync Iphone in Windows XP running as Virtualbox guest under Ubuntu 9.10

    - by steveth45
    I run (K)Ubuntu 9.10 as my main operating system, but I still have a valid XP license, so I've been running Windows XP as a guest operating system with Virtualbox 3.10. I cannot get Itunes (running under Windows XP) to detect the presence of my Iphone. I found this link: http://blog.rootshell.be/2009/01/15/iphone-itunes-virtualbox/ which explains how to get this Itunes-in-XP-in-Virtualbox-under-Ubuntu configuration to work, but it involves editing the file /etc/init.d/mountdevsubfs.sh which apparently does not exist in Ubuntu 9.10. Does anyone know how get Itunes in XP running as a guest in Ubuntu 9.10 to detect and sync with an Iphone?

  • Laptop will not boot

    - by WillumMaguire
    This is a dell studio 1558 laptop. Now, something is wrong with the charger that it won't charge the laptop, but the laptop can turn on and operate properly as long as it is attached. It has been like this for a while, but it's not the problem. My problem is that as of yesterday, It takes several minutes to get past the "dell" startup logo (where is says "f2 setup" and "f12 boot options"). After it gets past, it beeps as normal to tell me about the charger and gives me the f2/f12 options and f1 to continue as normal. I can press f12 to get into boot options and load into my live USB BackTrack 5 ISO, but after "startx" it just stays at a black screen. I can also access BIOS setup, but see nothing that would help the problem. When I boot to the HDD, it gives me this Intel UNDI, PXE-2.1 (build 083) Realktek PCIe GBE Family Controller Series V.2.29 (06/30/09) PXE-E61: Media test failure, check cable PXE-M0F: Exiting PXE ROM Operating System not found Also, pressing f8 gives me the same results as booting as normal. It is running Windows 7 Ultimate, dual-core Intel i3 @ 2.27ghz and 4gb RAM. I think there is an issue with the HDD, as the "Operating System not found" would lead me to believe. Is this a fixable problem?

  • What is the best answer for: "my Internet is not working"?

    - by Maciek Sawicki
    Hi, I look for work in IT Support. One of interview questions is: what would you first say if user call You and tell my Internet is not working? I think about it a lot and still don't know what is correct answerer nor what answer my future employer expects. My choice would be something like: What part of Internet? (but more polite). For example I could ask for opening web page that works on my PC. Please give only serious answers. If You want BOFH or "The website is down" style answers I can create separate question for that.

  • DNS server at router level vs. computer level

    - by Craig
    I've three questions. Is it better/faster/optimal to set up your server's preferred and alternate DNS servers in your OS's network settings or in your router settings? Will it cause problems if it is set up in both places, both pointing to the same IPs? I am running Windows and I have my network assign a static IP to one of my computers. This doesn't allow me to obtain the DNS server addresses from my router automatically. Is there an IP I can put in that will cause it to take the DNS server addresses from the router?
