• Unable to boot Ubuntu 64-bit in Virtualbox on Mac OS X

  - by Aamir

  I have latest generation Macbook Pro 7.1 (Intel Core 2 Duo) running Mac OS X 10.6.6. I installed Virtuabox 4.0.2 and tried to boot Ubuntu 10.10 64-bit iso. The boot options screen from the live CD came up: However when I continued to load the live session, or installer for that matter, I encountered the following error: This kernel requires an x86-64 CPU, but only detected an i686 CPU. Unable to boot - please use a kernel appropriate for your CPU. I am not sure if VT-x is enabled or is supported in the Core 2 Duo of my Macbook Pro. But at least, I have both I/O APIC and VT-x enabled for hardware virtualization as told in the Virtualbox manual.

• High level command line program for burning CDs and DVDs?

  - by stickmangumby

  I'm sick of screwing around trying to script a clean solution to burn multiple files and folders to CDs and DVDs with wodim, growisofs and genisoimage. I'm looking for a high level command line program that uses sensible defaults and takes arguments something like this: [program-name] [cd|dvd] /path/to/dir1/ /path/to/dir2/ /path/to/file ... It should then do all the low level copying and ISO generation transparently and just burn the damn disk! Does anyone have any suggestions? I've looked at several programs but it seems there are too many choices to trawl through and not enough information about them online. Thanks :)

• DoubleCommand Non-Functional on 10.6.3.

  - by Tim Visher

  I have a 1st or 2nd generation MacBook running 10.6.3. I want to remap my enter key to Ctrl and my right option key to enter (Emacs… yeah) and DoubleCommand seems to be precisely what the doctor ordered. Unfortunately, after having installed the latest version, it seems to be doing absolutely nothing. The correct settings are saved and active, but none of the remapping is taking effect. Are there any known issues with other OS X plug-ins (I run pretty heavily modified) or extensions that I should be aware of? What could the issue be? I initially tried to set only the User settings and then logged out and logged back in but nothing happened. I then tried saving them to System as well and logged out and in and nothing. Then I restarted the machine… twice… and nothing happened. Thanks in advance!

• Is the Zune HD's audio card better or worse than the iPod touch's?

  - by MatthewThepc

  Firstly, if this is the wrong site to ask this question I apologize, but I didn't see one for "music players" on the stack exchange website :) After reading a few people online say that music playing from a Zune HD sounds better to them than that on an iPod touch, I was wondering whether there's any truth to that? From what I can tell, the Zune HD uses a Wolfson Microelectronics WM8352, while the first-generation iPod Touch (which the Zune HD was competing with) used a Wolfson Microelectronics WM8758BG, and newer models use the Cirrus Logic CS4398 and CS42L61. Which ones are better (to make the question less subjective, let's say in terms of quality, range, & accuracy of output)? Admittedly, I have almost no idea how everything compares and works together, but it would seem to me that, just by looking at the version numbers, the iPod has been better since it's launch. Is there anything else that effects sound quality? Thanks!

• WesternDigital SmartWare - still problematic?

  - by FrustratedWithFormsDesigner

  I've seen a lot of bad press on WD SmartWare (I think it comes on most WD backup devices now, such as their MyBook product line), mostly related to how it's impossible to remove properly or replace. There are allegations (I couldn't tell how true they were) that it has/is a rootkit, as well. Most of the articles are a couple of years old, so I'm wondering if SmartWare is still just as problematic as it was. Does it still have a nasty rootkit reputation and should I just stick with the Windows 7 built-in backup system, or is the current SmartWare generation improved and better behaved?

• iPod Touch 2g not recognised by iTunes (more information inside)

  - by Jason

  My iPod Touch isn't being recognised by iTunes. Details: iPod Touch: 2nd generation / Laptop: Windows Vista / iTunes: latest version I have tried: using different cables; restarted my laptop and iPod. reinstalled iTunes. restarting services that were made by Apple; putting my iPod into restore mode; resetting my iPod; and still no luck getting it to be recognised by iTunes. This iPod works on other computers, and different iPod's work on my laptop. When I stopped all of the Apple services on my laptop, I got a message from iTunes when I connected my iPod saying that I needed to enable the services for it to work. But when I did enable the services again, the iPod still didn't show up on iTunes. I can't think what else I can do to solve the problem. Any ideas? Thank you very much in advance!

• Windows 7 on 1st Gen Macbook Pro (Q4-2008), power management problems.

  - by typemismatch

  I have the first generation macbook pro, purchased Q4 2008. I've been trying to run Windows 7 and can get it all installed great with the BootCamp 3.1 64 bit drivers however ... power management isn't great. The screen and keyboard don't automatically dim - the laptop gets too hot. I noticed on some newer macbook pros that windows 7 works perfectly and the above doesn't happen. Does anyone know if there really is a hardware issue with this 1st gen or is there some firmware update I can use to fix this? Thanks!

• kill SIGABRT does not generate core file from daemon started from crontab.

  - by Guma

  I am running CentOS 5.5 and working on server application that sometimes I need to force core dump so I can see what is going on. If I start my server from shell and send kill SIGABRT, a core file is created. If I start same program from crontab and then I send the same signal to it the server is "killed" but no core file is generated. Does any one know why is that and what need to be added to my code or changed in system settings to allow core file generation? Just a side note I have ulimit set to unlimited in /etc/profile I have set kernel.core_uses_pid = 1 kernel.core_pattern=/var/cores/%h-%e-%p.core in /etc/sysctl.conf Also my server app was added to crontab under same login id as I am running it from shell. Any help greatly appreciated

• How to ignore moved lines in a diff

  - by klickverbot

  I am currently working on a source code generation tool. To make sure that my changes do no introduce any new bugs, a diff between the output of the program before and after my changes would theoretically be a valuable tool. However, this turns out to be harder than one might think, because the tool outputs lines where the order does not matter (like import statements, function declarations, …) in a semi-randomly ordered way. Because of this, the output of diff is cluttered with many changes that are in fact only lines moved to another position in the same file. Is there a way to make diff ignore these moves and only output the lines that have really been added or removed?

• web spidering/crawling, can i do it or just search engines?

  - by bboyreason

  i already had a question answered about web-scraping with wget. but as i read a little more, i realize i may be looking for a web-crawling program. particularly the part about web-crawlers being able to get specific data like links or, in my case, products. all of the products on my site have the following naming convention, website.com/uniqueAlphaNumericID.html as far as i know, no dynamic content generation is being used and only one page per one item in the above format. should i just be thinking about: wget website.com | grep *.html or should i be looking into spiders/crawlers?

• Content delivery: Alternatives to SHOUTcast

  - by polemon

  I've been using Icecast and SHOUTcast for several years now, to deliver audio and Video content. I wonder what kind of alternatives do I have to those two, especially when streaming video. On the client side, what software can I choose from to stream to those servers live? Making the streams available with Flash would be great, but that's maybe another story. We're still using EdCast, which is kinda dead by now, Shoutcast DSP plugin is not an option, as this tends to crash, etc. Are there any alternatives to that, when livestreaming video? I'm using Liquidsoap for content generation, mixing, etc. It should work with Icecast, Liquidsoap and if possible SHOUTcast.

• SSH rsa key works with external IP not internal IP

  - by Ian

  I am using rackspace cloud hosting. I have 2 servers behind a load balancer. Each server has an external IP and an internal IP. I want to setup a sync job that uses SSH to transfer files. I made an rsa key, and I can successfully SSH from server A into server B, using the external IP of server B, without being prompted for a password. If I try to do the same but use the internal IP, it prompts me for a password. I want to be able to use the key instead of the password. Why is this? Is there something special I have to do during key generation so it works for both IPs? Any help is appreciated.

• Is it possible to use a dual processor computer as your desktop?

  - by Ivo Flipse

  I've seen some people suggesting to get a motherboard that supports two processors and stick two Xeon Nehalem processors in it. Could you use this system as a desktop PC or is this useless or even impossible? It's more hypothetical question if Windows 7 would support such a set-up. I know you could just take an i7, but wouldn't two of those processors be a whole lot more awesome? Like the previous generation Skulltrails? The idea would be to have a motherboard like this ASUS Z8NA-D6C Dual LGA 1366 Intel 5500 ATX and two Xeons (since I don't think i7's could be used) Intel Xeon E5405 Harpertown to run something like Windows 7 Ultimate.

• Puppet:get real-time status of catalog evaluation and post to remote server

  - by txworking

  According to this article http://docs.puppetlabs.com/guides/puppet_internals.html There are four phases when puppet agent got a catalog from master. resource generation = relationships = evaluation = reporting Reporting As the transaction progresses, it collects logs and metrics on what it does. At the end of evaluation, it turns this information into a report, which it sends to the server (if requested). And at the end of evaluation puppet agent would generate a report and sent the report to the master. Is there a way to get real-time status of evaluation phase and post them to a remote logcollector? Glad for any suggestions.

• Uploading my ITunes music that I saved on a flash drive to ITunes on my new computer then downloading it to my Ipod Touch

  - by Joshua Kricker

  I had an old computer with Windows XP. I transferred all my music, at least I hoped I had to a flash drive. Also, my computer kept giving me error messages that it could no longer sync to my Ipod Touch First Generation. I reformatted my Ipod back to original factory specs on the old computer. I have a new computer with Windows 7. I can't transfer my music from my flash drive to the ITunes Library. I also can't transfer it to my Ipod. I keep getting the message "Songs cannot be added to the Ipod because all of its space has been reserved for data." There's nothing in the Ipod memory. It's clear. What can I do? I want my music back.

• how can I get rid of duplicate administrators on 2 macbook pro's

  - by BCITY

  I got a new MacBook Pro (insurance payout) and passed my old one (previous generation MacBookPro 2008) on to a staff member whose MacBook Pro died. I used carbon copy to move my data to the new laptop but couldn't do the same with her move as the older Macbook wouldn't allow it as it was on an old OS. Ended up just migrating her software onto my old MBP. Now however, they both have the same admin identities and her computer is synching with my mobile me account. Can I change the administrator identity and save all her applications? I am hoping that I don't have to wipe and reinstall everything to change her computers identity.

• Enterprise Level Monitoring Solution

  - by Garthmeister J.

  My company is currently looking to replace our current solution used for monitoring our web-based enterprise solutions for both up-time and performance. Please note this is not intended to be a network monitoring-type solution (internally we currently use Nagios). If anyone has a provider that they have had a positive experience with, it would be much appreciated. Here is a list of our requirements: • Must have a large number of probes/agents around the globe to be representative of our customer base • Must have a flexible scripting capability to automate multi-step user actions • 24 hour a day monitoring • Flexible alerting system • Report generation capability • Mimic browser specific monitoring (optional, not a must-have)

• Ultrabook graphics card for gaming

  - by Francisc

  I want to get a Windows 8 "ultrabook" that I can also use for gaming. Most seem to have Intel HD Graphics 4000 (integrated) or NVIDIA GeForce GT 620M (dedicated). From experience, are they any good? Things I enjoy playing are Call of Duty, Fifa and Skyrim for example. I'm looking for a device that will work on the next generation of those games as well, so it shouldn't just barely work on the current versions that exist now. So, would those two cards suffice? Any advice is much appreciated. Thank you.

• Can I rent exclusive time on a powerful server running linux? [closed]

  - by Mark Borgerding

  My company is involved in a proposal that requires speed estimates of our software on a server with the latest & greatest processors. This is not the first time we've been in this situation. The servers themselves are too expensive to buy a new one every time, so we end up extrapolating from what we have. There are so many variables: processor generation & speed, memory speed, memory channels, cache configurations; it makes extrapolation difficult and error-prone. Is there a business that rents time on the newest servers? At least part of the time we'd need exclusive access to an otherwise quiescent system either via ssh shell access or unattended batch jobs. I am not looking for general cloud computing services. I don't need much time on the server, but it needs to be exclusive. And the server needs to be pretty cutting edge for a solid basis of estimate.

• Code-First Database Creation During TFS 2010 CI Build

  - by jedimindtrickster

  I would like to automate code-first database generation during the automated CI build of a web project in Team Foundation Server 2010. When run locally the tests create a code-first database specified by the connection string in the app.config of the tests project. How do I configure the TFS Build Configuration to mimic this behaviour on the TFS build server? Edit The problem, it turns out, was that the TFS build server was successfully running the test which was using the default connection string in the app.config which pointed to the local SQL Server, not where I expected it. The solution was to use SlowCheetah on the TFS server as a means to transform the App.config file using the QA transform as per this blog article.

• Is the quadro 4000 still worth it's price? [closed]

  - by aknewhope

  I am going to be purchasing a quadro graphics card for learning 3d CAD at work. It's not critical I have it right now otherwise I would just buy the current 4000 (PC). I am buying this with my own money and am concerned Nvidia will release a new Quadro 4000 sometime in the near months. Is the current 4000 still worth it's price tag at $700.00? If i were to purchase it, how long would it be useful? I am going to be running E-PLAN, SOLIDWORKS, DRAFTSIGHT, MASTERCAM. My computer is a second generation i7-2600k with z68 chipset (intel DZ68BC mobo).
