• Are Mac Minis suitable for a proper desktop computer?

  - by alex

  I've read about a lot of people using their Mac Minis as a file server, or media centre or something similar. Does the mini function alright as a standard desktop PC? The Mac will be used primarily for web development, that is, it will need to run Coda, Photoshop, possible Firefox and Safari at the same time. So it will need suitable performance. Or am I better off getting an iMac? I though the mini looked like a good option because: cheaper I already have a keyboard, mouse and 24" monitor I could use a KVM between the mini and PC Also, does the mini support multiple monitors? Thanks

• What influences the kind of RAM a desktop or laptop can support?

  - by Albert Iordache

  What exactly influences the kind of RAM a desktop or laptop can support? Apart from the clock speed, the maximum amount of RAM the motherboard can handle, the DDR type (1/2/3) and the shape of the module (DIMM for desktops, SO-DIMM for laptops)? I see that in certain cases, such as with the Kingston 4GB DDR3 1333MHz CL9, (and on the Kingston KTD-L3B/4G page) the page displays a set of laptop product numbers. Does the actual model of the laptop also influence the models of RAM it can support? Could, for instance, an Asus K52 work with that particular RAM module, even if it specifies Dell models?

• internet access options in remote area? (read: no comcast,qwest, etc)

  - by freedrull

  Currently I am living in a fairly "remote" area, in the countryside, and cable internet access through the typical companies like comcast and qwest is just not available here. I've been trying to research other options for fast internet access. There are some small cable companies but they currently do not offer broadband access here. I thought about maybe buying a 3g phone with a data plan and doing some sort of tethering, or perhaps getting an android phone and using it as a wireless AP. This would of course depend on 3g being available here. The only other thing I can think of is some sort of satellite internet service, or doing something crazy like adapting wifi over am radio. Anyone have any ideas, at all, short of moving somewhere else?

• I install Ubuntu 13.10 and reboot and im on KDE desktop?

  - by jgamer578

  Hi I'm Jacob and I have no idea what's going on. I installed Ubuntu 13.10 today and was playing around with it for a while and dl'd a bunch of apps from software center and stuff. Eventually I installed steam and (finally) got it working. I downloaded TF2 and had some weird issue where the screen got so distorted to the point I could not play. So I dl'd a driver for my graphics card from the additional drivers app (or whatever it's called) and when it was done I restarted my computer (because it said to.) When the PC booted up it loaded the KDE desktop and I have no idea why. I had unity before I rebooted. Ubuntu 13.10 is the only OS installed on my PC, and I still have all the apps that I downloaded, but I kinda like unity (I started using Ubuntu after they switched to unity) and want it back. Thanks for reading and any help in advance, Jacob.

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

  - by Ivo

  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.

• How can I store Rails uploads on a remote server (and not a common cloud host)?

  - by joshee

  I would like to store uploads from a Rails application on a different server than my application server. I want to keep costs to a minimum and host this other server in-house. I am planning to use Carrierwave for uploads. It seems Carrierwave interfaces with Fog for remote hosts. Is there a way I could set the other server to act as a Fog provider? How would I go about this setup? Or, is there some better and easier way to go about all this?

• Youtube videos all appear transparent in Chrome (I can see through to my desktop -- see pic!)

  - by kalaracey

  MBP 6,2 :: Google Chrome 13.0.782.32 beta :: Adobe Flash Player 10,3,181,26 UPDATE: only Youtube is affected. Vimeo, other flash, etc. all works great. Hello. I recently had to hard reboot my MBP. After that, I could not watch Youtube videos or (I believe) other flash enabled content. The videos appear transparent, as if there were a "hole" in my browser (Chrome) such that I could see through the hole and see my desktop. I've attached a picture (just picked a random video) Thanks.

• Is there a remote file transfer command that preserves nanosecond timestamps?

  - by Denver Gingerich

  I've tried transferring files using scp and rsync on Ubuntu 10.04, but neither of them preserves more than second precision. Here's an example: $ touch test1 $ scp -p test1 localhost:test2 $ ls -l --full-time test* -rw-r--r-- 1 user user 0 2011-01-14 18:46:06.579717282 -0500 test1 -rw-r--r-- 1 user user 0 2011-01-14 18:46:06.000000000 -0500 test2 $ cp -p test1 test2 $ ls -l --full-time test* -rw-r--r-- 1 user user 0 2011-01-14 18:46:06.579717282 -0500 test1 -rw-r--r-- 1 user user 0 2011-01-14 18:46:06.579717282 -0500 test2 $ A straight copy works fine, but scp truncates the timestamp. Are there any tools (preferably similar to scp or rsync in their usage) that do remote file transfers while preserving nanosecond timestamps? I could write a hacky script to do it, but I'd rather not.

• How to config putty remote port forwarding to connect mysql?

  - by kev

  I installed MySQL to a Windows box. I want to connect it from a Linux box. I run plink to setup a remote port forwarding in Windows box. I try to connect it from Linux box, but it's not working.

• ubuntu-10.04-desktop-i386 does not work with HTTP preseed?

  - by netvope

  Installation media: ubuntu-10.04-desktop-i386.iso I tried a lot of different boot parameters, but either the installer ignored the preseed configuration, or it boot itself directly as LiveCD. An example of the boot parameters I've tried: auto url=http://mydomain.com/path/preseed.cfg boot=casper only-ubiquity initrd=/casper/initrd.lz quiet splash -- If I remove only-ubiquity, it boots as a LiveCD. If I remove boot=casper, it won't boot. If I add vga=normal locale=en_US console-setup/layoutcode=us console-setup/ask_detect=false interface=auto, it still can't do automatic install. If I remove auto, it's the same. What is the correct boot parameters for launching such an installation? From the apache log of the server hosting preseed.cfg, I see that the installer has no problems fetching the preseed file. My preseed file is almost identical to the one at https://help.ubuntu.com/10.04/installation-guide/example-preseed.txt. Moreover, I have run debconf-set-selections -c preseed.cfg to ensure that the preseed file is correct.

• How to use WeirdX applet instead of X11 for remote connections in Mac OS X?

  - by penyuan

  When I am away, I've got an Apple PowerBook set up to use X11 forwarding with SSH to connect to a remote iMac client in my room for server administration. Whenever I start X client programs on the client iMac, X11 would start on my PowerBook, which is OK, but... Question: Is it possible to change my settings so I can use the WeirdX (a web-based java X server) applet to take care of the X client programs instead of Mac OS X's default X11? Is there a config file I can edit to chance the $DISPLAY variable, and what should I set it to? Is this even the issue? Thank you very much.

• How to take a screenshot on Windows 7 and auto create screenshot file on desktop like Mac?

  - by Ali

  I'm trying to find information how do we take a screenshot on Windows 7 that will actually create a screenshot file like .png in to your desktop like on mac where you can do it by press Command+Control+Shift+4. In windows all I know is that I can do it by press press = Windows captures the entire screen and copies it to the clipboard. or for the Active windows I can just do hold and press = Windows captures only the currently active window and copies it to the clipboard. Right now I'm using maComFort which it gives me functionality of Mac like keyboard that I can take screenshot in such the same way with Mac OS X but really it changes many of the key in my keyboard in the way I don't like. So I wonder if there is a better way?

• How does one guarantee a remote client the same local IP address every time when connecting to a VPN?

  - by Joe Carroll

  I need to configure a VPN for secure remote access to a PACS serving DICOM radiological images. The DICOM standard requires that any clients accessing the PACS must be using a fixed IP address that is pre-registered in PACS. I haven't implemented this solution before and would appreciate any guidance. I believe it should be possible to use RADIUS on the server to authenticate users connecting to the VPN and with it assign each user their own specific local subnet IP address, which would be registered with the PACS. The server runs Windows Server 2003 R2 Enterprise Edition SP2 and the VPN device is a FortiGate 60C. The What would be the best and/or simplest way to set this up?

• Advise about performance for local or remote SQL Server?

  - by TruMan1

  I currently have my web server and SQL Express / MySQL server on the same server. It is on a VPS. I have been having problems with my hosting so I am thinking of separating the web and db server into 2 VPS servers. Does anyone recommend this? I am worried that changing my setup from a local DB server to a remote one will degrade performance heavily. They will not be on the same network, but will reference each other via an IP address. Anything I should be aware of?

• telnet to 3389 connects, RDP remote desktop app bails ?

  - by scott_lotus

  I can TELENT 192.168.10.10 3389 and get a connection. But RDP client to 192.168.10.10 immedietly bails (i.e less then 1 sec) "connect" button greys briefly, RDP app remains on screen. Have tried these from many nodes on the subnet to 192.168.10.10 with same result. On 192.168.10.10 Allow Remote Desktop is enabled. On 192.168.10.10 windows firemall is off. Im connecting from the same subnet i.e no firewall hardware / routers in the way. AV software is installed but other nodes on same subnet allow RDP connection using exact same AV settings (network group profile) Checked 192.168.10.10 for any additonal AV software or local firewall products. Im sure non exist. Checked regedit to ensure 3389 was the port set for listening. Seems to be an XP problem (sp3) ( 2 nodes on the my LAN have this issue) and many work fine. Thanks for any help Scott

• OpenVPN to connect remote networks, peer to peer instead of client/server possible?

  - by John Robertson

  I would like to connect two remote networks using OpenVPN. I am very new to this we are very small and don't have a sys/network admin. What are the possible setups to have both networks both live on a common LAN via OpenVPN? I would prefer to use the UDP peer model rather than client/server. Is there a way to set that up instead? I can't see how because no computer on existing network A has a routable address to any computer on existing network B and vice versa.

• How to remove the Ubuntu Gnome desktop after making the switch to KDE?

  - by codeLes

  This is the opposite of this question. Basically I've been using Ubuntu for a while but decided to give KDE a shot so I went through the process of getting the latest KDE installed. I'm very impressed with KDE and the Kwin window manager seems like a better WM than Compiz which is what I was using for Gnome (sure that's an oppinion). This was an Ubuntu Jaunty install. So how do I go about removing the Gnome desktop? Is there an automated way similar to what my previous question covered? UPDATE: Should there be any packages I should NOT remove in the process?

• installing SQLite3 gem on remote FreeBSD server using RVM - root permissions needed?

  I am trying to install ruby SQLite3 gem, on a remote freebsd server.

• How Can I Override the Remote Administrator security policy on Android 2.2 so that I can disable the lock screen?

  - by hagope

  On Android 2.2 Froyo, I added my Corporate exchange email account to the phone, however, the security policy set by the "remote administer" requires that I enter a 4-digit PIN at the lock screen and a maximum 10sec idle. How can I hack my Android, through root access or otherwise, such that I do not need to follow this security policy. I am very annoyed at having to enter the PIN every time I want to use the phone, because I open/close it so often through out the day? Please help...I'm so surprised at how difficult it is to find the answer!

• Sending emails with remote mail server in ASP.NET blocked by Windows firewall?

  - by Dave

  I want to migrate a web application from a Windows Server 2003 to a Windows Server 2008 R2. All works fine except sending emails from the application. If I configure the application to use the smtp server on "localhost" it works, but changing it to the "real" host name (e.g. mail.example.org) no mail is sent. The error message says, that the remote server needs a secure connection or smtp authentication. But since it works when using "localhost" instead of the host name I doubt that this is the problem. Also it's unlikely a problem with the mail server, I also tried it with another one. So for me it seems like the firewall is blocking the outgoing connection to the mail server. I tried to open port 25, but it still did not work. Maybe I just did it the wrong way.

• What version of Ubuntu to use for Desktop with 8Gb RAM?

  - by Alexander

  This may sound as a stupid question, but I am really interested whether Ubuntu Desktop i386 will be able to use all my available RAM. I want to use the latest, non-LTS version, 10.10. It says on the website that it's (i386) the Recommended version. I also recall that Flash Player had issues with 64 bit Linux. Also, the 64 bit version is listed in the Universal USB Installer as amd64. Does this mean that it's using instruction sets specific to AMD CPUs? (I have an Intel) Will it work fine with Intel? So which one to download and install? What to do to be able to use 8Gb of RAM?

• How to print index in a 'for-loop' being executed in remote host through SSH?

  - by YShin

  I want to ssh into a remote host, and then execute a for loop that goes through sequence of numbers to control number of different nodes. ssh user@host /bin/bash << EOF for i in {1..10} do echo $i done EOF If I do this, the output is just 10 blank lines, instead of printing out numbers from 1 through 10. If I execute same code on my local machine, I get the desired output which is ten lines each line printing from 1 through 10. How would one achieve the intended functionality, that is accessing the index in a for loop that is being executed in SSH?
