Is it better to run a VM on a dual core hyperthreaded machine as a four core or as a two core VM.
The hyperthreaded 'virtual' cores are not as fast as the real cores. Does this effect the VM?
I use a terminal with white text on black background (I just like it better), so I wrote the following line in my .vimrc file:
set background=dark
However, gvim has black on white text. How do I do either of the following:
Set the background of gvim to black
Check in .vimrc if I'm using gvim
I tried this: I started up gvim, and typed echo &term. The answer was "builtin_gui". So I wrote the following into .vimrc:
if &term == "builtin_gui"
set background=light
else
set background=dark
endif
Somehow, it didn't work.
I have discovered that my email server has been blacklisted by http://www.five-ten-sg.com
What affect is that going to have on my sending and receiving emails and is there anything I can do about it to fix it.
All the emails I am sending are going out by IIS6 SMTP server, so any suggestions for how to configure this better gratefully received.
The first thing I like to do before I make technology choices or gadget purchases is find bad reviews of the things. That way, taking into consideration of the potential biases of the reviewer, I can evaluate the product/service for the worse it can be.
How do people google (or search in general) for bad reviews?
I usually just try googling "bad review [product/service]" or "[product/service] sucks", but I'm sure there are better ways.
There are tools that can read iPhone backup files, but only when they are not encrypted.
Is there a way to remove the encryption on these files (with knowledge of the password, of course), so that they can be read?
Or better yet, is there a tool that does support encrypted files?
I am running Windows 7 and have adjusted something which has caused all of my shortcuts and program icons to show the same program namely Adobe Reader and when I click on any of the icon or shortcuts they only open Adobe reader, I have reinstalled Windows 7 But this has made no change, I posted this question yesterday but apparently with not enough information I hope this isbetter and someone can help.
I have little experience with Windows systems. Coming from a Linux background I was wondering if there is a way that I can ssh to powershell from a Linux shell?
If this is not possible, is there a key exchange like way to connect from powershell to powershell? I prefer it if I do not need to enter a password for every single server every time.
If this all sounds a bit crazy and there are better ways that windows does this, then feel free to share.
I connect to a share on a windows server and I have a quota of unknown size. All the tools I have seen are reporting the disk size/disk free space, not the quota size for myself.
The only way I can figure out my quotas is to keep writing junk until I reach the quota. There must be a better way than this?
My PC is windows XP and the servers are mainly 2003server.
I have a small java project that handle connections.
In order to run it from the terminal I have to cd into the folder that contains the source and run the following command:
java -cp classes com.packagename.mainclass
Where classes is the folder that contains the classes.
I want ubuntu to run this application on startup, is there a Java command I can use? Or am I just better off creating a shell script?
Thanks!
Some OEM include energy saving apps that can switch off certain devices such as webcam or optical drive. Is there any brand-agnostic app out there that can do it? If the list of disabled device is customizable, it would be useful too for mitigating DMA attack (disabling Firewire, PCMCIA, SDIO, Thunderbolt, etc). Even better if it can recognize lock/logoff event, to mimic OSX behavior in mitigating the DMA attack.
A friend has a site developed in ColdFusion with MySQL and is looking for better cost-effective hosting as the traffic scales up rapidly. Azure comes to mind.
I haven't used Azure myself, however, I believe it is possible to setup and interact with the web-server via RDP into a hosted Virtual Machine?
I am curious if ColdFusion can be installed in the hosted Azure VM. Also, would the site have to be tweaked to run on Azure SQL, or could it continue to use MySQL?
Thanks.
I bought a small 256MB slice from slicehost and installed Ubuntu 10.04 64bit and wordpress on it. Performance was dismal as apache was eating up all my memory. Once I did some taming of apache and switched to fCGI things ran fine.
Next I rebuilt as a 32 bit server, and performance was much better.
What benefit would I get from a 64 bit server. Is it all about the memory?
I want to give direct out put to the Speaker of my laptop, I am able to do that by recording then play.. but I want to do it live.
Please help me to find the better option.
thanks in advance
It is very expensive always to use most modern hardware especially buying new mainboard if only a new CPU is desired. It would be much better if one knows whether and when major CPU producers plan to change CPU sockets. Do you know when it is planed to change sockets the next time? I am particularly interested in not buying Intel i7 CPU if a new CPU will be released soon with not compatible pins.
I know there may be a few questions similar to this, but my question is regarding specific hardware configuration.
I have an Asus U52f laptop with an HDMI out that I currently use to drive my 24" DVI external monitor. My question is I found an HDMI - dual DVI splitter here and was wanting to know is has anyone tried this type of configuration or would the Matrox DualHead2Go be a better solution.
any utility on windows 7, which gives me virtual/multiple desktops like linux.

anyone voting for this app, or is there anything better available.
I have a Windows 7 desktop running Firefox 4. If I remote-desktop (RDP) from another PC into my already-running session, the Firefox window turns black. Flash applications are still visible, if I'm on a tab with one, and I can apparently interact with Firefox normally, I just can't see anything in the window. I'm after an explanation, if possible, and (even better!) a workaround or fix that doesn't involve a different web browser :).
I've installed ubuntu 10.04, hoping to get rid of the 9.10 errors. (Nvidia driver didn't work quite properly, had some problems with clicking in flash, and I had -and still have- wired network working, but ubuntu said that it's disconnected)
So the Nvidia driver isbetter now, but the network error is the same. I still have a working wired network connection, but when it starts says that it is disconnected. Notification area tells me the same thing.
Why is that?
Around here the clusters (not hyper-v clusters) are typically configured as n+1, so they are asking me to create a n+1 hyper-v r2 clusters. These will configured with both csv's and live migration and managed via scvmm r2. My thinking is that its a waste in having a node sitting there idle. In my opinion it would be better to have headroom left over for what would traditionally the +1 server spread amongst the N nodes. Anybody have an opinion on this.
thanks

we recently added a MacPro with eight (yes 8) monitors on it. We have various tools for monitoring our website (Chartbeat, Nagios, internal statistics, Jenkins, Smartfox, etc.) and they are currently free-flowing in various browser windows on the various screens.
I'd like a better way to organize them into a more fixed system so
(a) we can't just accidentally close out of a window
(b) some automatically refresh (currently done through browser plugins)
etc.
Any suggestions?
As long as my tables were less than 100, MySQL performed reasonably well but when they started to grow to more than a few hundreds, it (MYSQL) has become extremely slow. Now my tables are 1k and are very small and most contain less than 20-30 records.
Is there a specific MySQL setting which I should consider, in order for MySQL to perform better with large numbers of tables?
I would like to setup the Remote Desktop Connection Broker to allow better load balancing of the two terminal servers we have as well as allowing the user to re-establish to the correct server if they get disconnected.
My worry is, if I set this up and the server this service is running goes down, does the terminal server stop accepting connections or will they just lose the benefit of having RDCB turned on? I don't want to add another point of failure in this equation unless I have to.
I want to configure DHCP server in a way that it puts "regular" smartphones and tablets into a separate subnet. Is it possible to detect if the DHCP request comes from an Android or iOS device based on the DHCP request itself?
For example: a Sony android phone which was around set the following DHCP options in request, which are potentially useful for identification
bootp.option.vendor_class_id == "dhcpcd-5.2.10:Linux-2.6.32.9-perf:armv7l:mogami"
bootp.option.hostname == "android-c7d342d011ea6419"
Are there any known common patterns in DHCP request options better then MAC prefix?
My Windows DVD Maker stops/freezes the encoding process on some movies that I have converted to AVI files. Is there an answer to this using Windows DVD Maker? Or is there another software product that is better? (using Windows 7 Professional)
