• Is an eee-pc with an Atom N550 dual core OK for Rails 3 development?

  - by dan

  I'm buying an Asus eee-pc 1015PEM and hope to do test-driven Rails 3 development on it. Is the CPU fast enough or too painfully slow for this? I plan on installing Ubuntu. I currently develop on a 11 inch Macbook Air 2010 model. It works fine as a Rails development machine. But for some reason I'm drawn to developing on a cheap little netbook. I don't use any IDE's, and my development workflow is mostly switching between Vim, Gnu Screen, and bash.

• TCP/IP performance tuning under KVM/Qemu

  - by vpetersson

  With more and more companies switching to public cloud services, I'm curious what you guys' thoughts are on TCP/IP tuning in the cloud. Is it worth bothering with? Given that you don't have access to the host-server, you're somewhat limited I presume Let's say for the sake of the argument that you're running three MongoDB-servers in a replica-set on FreeBSD or Linux that all sync over an internal network. I'd also be curious if anyone made any actual performance benchmarks to back up their arguments. I benchmarked the various network drivers available for KVM/Qemu here, but I'm curious what the gurus here suggest to tune further. I started playing around a bit with the tuning-recommendations as suggested over here, but interestingly enough I saw a decrease in performance, rather than an increase, but perhaps I didn't fully understand the tweaks. Update: I did a few more benchmarks and posted the result here. Unfortunately the result wasn't really what I expected.

• Toggle "ask for password after screensaver/sleep" or the delay in 10.7 using terminal

  - by desbo

  There's an option in the preference panel to change the time the mac is able to be in sleep/screensaver before requiring a password to be unlocked again. I'm using OS X Lion 10.7. Is there any way to change this setting using the terminal or an applescript? I tried to change the plist file using: defaults write com.apple.screensaver askForPasswordDelay -int 60 also tried defaults write com.apple.screensaver askForPasswordDelay -float 60 also completely disabling the password didnt work either defaults write com.apple.screensaver askForPassword -int 0 The plist file was changed, but it had no effects at all. It's the same plist file that gets changed when manually switching the setting in the preferences. Would be awesome if anyone got an idea how to fix my problem. EDIT: also tried to: 1) add -currentHost flag 2) drop the -int / -float

• Upgrading from php 5.3 to php 5.4 with Macport

  - by dr.stonyhills

  PHP5.4 has been available for sometime now and Macport recently caught up with the release of port php54 but the process of upgrading is not as clear as possible. Even worst for those who are new to maintaining multiple versions of PHP on the same machine. I am keen on trying out some of the new features in PHP5.4 like traits, new array form etc but falling back on to php5.3 for other compatibility stuff. So i sudo port install php5+ (all the variants, apache2 etc) Then i tell it what PHP port to use as default sudo port select --set php php54 Check what version of PHP is active in the terminal using php -v outputs php 5.4.3. But i seem to be having issues with choosing the right non cli version as in the version of the module run by apache etc is still php5.3.12. Do i have to change the reference to the libphp5 in apache httpd.conf? Any advice on the right workflow for switching between php version on macport greatly appreciated!

• Understanding why a 450W power supply is destroying my ATX motherboards but not mATX

  - by T. Webster

  Maybe I'm missing something really obvious here, but after going through 3 new motherboards in trying to build my new machine, I'm finally certain that the 450W power supply I bought has been destroying them. It seems like it should be simple: just connect the connectors where they fit and switch the thing on. But today after hooking it to my ASUS Sabertooth 990FX TUF Series Motherboard and switching it on, I could see and smell the smoke coming out of the motherboard. What I don't get is why I can hook this same 450W power supply up to my mATX motherboard and not run into the same problem. What am I missing here? Where on the box or manual is this? (I have 8x2 GB RAM, AMD FX-4100 3.6GHz CPU, 1 512MB ATI graphics card, 1 WD 7200 RPM SATA hard drive. )

• Why are applications slowing down on the computer's second monitor?

  - by ChristianLinnell

  Here's an interesting one. Problem I have a user on Windows XP who is running a web application inside IE8. She has two monitors plugged in via DVI cables. When she is working the the browser on her primary monitor, everything is fine, but when she drags the window over to the second monitor, the web applications functionality grinds to a halt. It's not just web apps either - many applications exhibit the problem. What I've tried Switching the two monitors in the OS. It's obviously not the monitor's fault. Confirmed that it's the app slowing down, and not the graphical rendering. The application in question actually locks up. The mouse is unaffected, and I can drag other windows on top of the problematic application. Any ideas?

• Suspected power supply issue? PC repeatedly whirs for some seconds and then dies.

  - by benwebdev

  I've come home today and switched on the PC I've built a few months ago only for the machine to whir for a few short seconds and then die. It repeats this until I disconnect the power lead. Nothing is output to the screen and this cut out happens very quickly after switching it on. What could this be and how could it be fixed? Is it the power supply? I'm in despair :-( My spec is below, everything is new and was bought and assembled within the last 6months, system has been fantastic until now. Power Supply: 620W CoolerMaster Real Power M620 Motherboard: Gigabyte GA-X58A-UD3R Intel X58 (Socket 1366) DDR3 Processor: Intel Core i7 930 2.80GHz @ 4.00GHz RAM: 6GB DDR3 OS Windows 7 64bit Sapphire HD 5770 Vapor-X 1GB Graphics card 1TB Hitachi HDD 720GB Seagate Barracuda HDD 350GB Seagate Barracuda HDD EMu 0404 PCI Soundcard D-Link PCI-E wireless card Samsung DVD RW drive

• ^+Left Arrow and ^+Right Arrow suddenly stopped working on OS X

  - by user31122

  Hello. I'm not really sure what to make of this. The key combination of ^? and ^? have stopped working for one of the two users on my OS X installation. I use these keys all the time (switching tabs in terminal, IntelliJ primarily), and it's driving me crazy. On one user account, it works fine. On the other, it doesn't. This happened today and nothing significant comes to mind that would have caused some weird keybinding issue. If anyone has heard of or experienced anything like this, I would very much appreciate your advice! Thanks.

• Windows 7 connect to Lion file sharing

  - by Automaton

  Trying to access my Mac from a Windows 7 computer, I fail with the infamous error 86 incorrect password. Now this appears to be a well-known problem with countless threads on the internet giving as many "solutions" as there are discussion threads about it (mostly ranging from installing third-party commercial samba servers, to switching to some other protocol, to compiling a plain-vanilla Samba installation - the latter which I will probably do when I give up this :) ) I am stubborn, and I believe there must be some problem here that can be solved or worked around, but there is surprisingly little detail about this problem. It appears to have something to do with a mismatch of authentication methods. Trying to run samba in debug mode: sudo /usr/sbin/smbd -debug -stdout gets me this output when trying to access it from Win 7 ... smb1_dispatch_one [smb_dispatch.cpp:377] dispatching SMB_COM_SESSION_SETUP_ANDX smb1_dispatch_session_setup [session_setup.cpp:261] FIXME erase existing sessions log_gss_error [gssapi_mechanism.cpp:97] gssapi: gss-code: Miscellaneous failure (see text) log_gss_error [gssapi_mechanism.cpp:113] gssapi: mech-code: unknown mech-code 22 for mech unknown What is the problem here, and how do I fix it?

• Server suddenly running out of entropy

  - by Creshal

  Since a reboot yesterday, one of our virtual servers (Debian Lenny, virtualized with Xen) is constantly running out of entropy, leading to timeouts etc. when trying to connect over SSH / TLS-enabled protocols. Is there any way to check which process(es) is(/are) eating up all the entropy? Edit: What I tried: Adding additional entropy sources: time_entropyd, rng-tools feeding urandom back into random, pseudorandom file accesses – netted about 1 MiB additional entropy per second, problems still persisted Checking for unusual activity via lsof, netstat and tcpdump – nothing. No noticeable load or anything Stopping daemons, restarting permanent sessions, rebooting the entire VM – no change in behaviour What in the end worked: Waiting. Since about yesterday noon, there are no connection problems anymore. Entropy is still somewhat low (128 Bytes peak), but TLS/SSH sessions have no noticeable delay anymore. I'm slowly switching our clients back to TLS (all five of them!), but I don't expect any change in behavior now.

• md5sum of large files gives different results sometimes

  - by Emanuele

  I have an AMD quad core, 8 gb RAM, 1 SSD EXT2 (2 months old), 2 HDD EXT4, approximately 1 year old. I'm using Ubuntu 10.04 x86-64 and when I compute the md5sum of large files (9 GB) sometimes I get different values than the one stored on a reference file. Upon restarting and switching off the PC then I get the expected results no matter how many times I repeat it. But this is random. I've turn on ECC (the fastest possible settings) and the issue seems to be rarer, but I've run memtest86+ for 6+ hours without a glitch (and with ECC off!). Any idea? Should I update the BIOS of my motherboard (Asus EVO-something...don't remember it now)? I've tried all the rest apart this, but genuinely don't know what to do anymore... Any suggestion is appreciated!

• How to make VIM settings computer-dependent in .vimrc?

  - by Paperflyer

  I share my VIM configuration file between several computers. However, I want some settings to be specific for certain computers. For example, font sizes on the high-res laptop should be different to the low-res desktop. And more importantly, I want gVIM on Windows to behave more windowsy and MacVim on OSX to behave more maccy and gVIM on Linux to just behave like it always does. (That might be a strange sentiment, but I am very used to switch mental modes when switching OSes) Is there a way to make a few settings in the .vimrc machine- or OS-dependent?

• Increase the compression performance of VPN

  - by Martin

  I am currently switching from a system with HPN-SSH tunnels and enabled compression to something VPN based. I have tried tinc and n2n so far, hamachi requires a library I do not have. In my primitive benchmarks I am not satisfied with the achievable bandwidth compared to the SSH tunnels. In tinc the low LZO setting performed best, but compression is only available in UDP mode. Ideally I would like to have a TCP-based VPN with a multi-threaded compression. Can you suggest me some ideas how to increase the performance? Would it be possible to somehow put a compression filter in front of the tun interface? Or are there any VPN implementations that might be better suited for my needs (fast compression, TCP-based, switch mode, does not have to be super-secure)? I would consider tunnelling Ethernet over SSH, but according to some articles it is not advisable.

• Invoke host's workspace switcher from inside VM

  - by Paul

  When I start a virtual machine (like VMware or VirtualBox) and set it full screen then, from the host OS (in this case Ubuntu), I can beautifully switch to it with the Workspace Switcher. So I switch to the VM like I switch to a virtual screen. But switching back -- from the VM to the host's virtual screens -- seems to be impossible because by entering the VM I loose the host's workspace switcher. Is there a nifty workspace switcher program that runs inside the VM and is able to switch workspaces of the host machine? Edit in light of Frank Thomas' answer, can we configure VirtualBox (or VMware) to not send certain key combinations to the VM, but keep them to the host? Like Super+S. In that approach I would sadly have to miss the nice workspace switcher icon in the guest OS, but that's OK if at least the keyboard trick would work.

• Does changing web hosts (changing a domain's nameservers) affect the private nameservers / glue records created under that domain?

  - by Kris

  We currently have a virtual dedicated server with GoDaddy and have 4 domains under it. I ended up creating private nameservers under, say mydomain_a.com, and have ns1.mydomain_a.com and ns2.mydomain_a.com as the nameservers for the other 3 domains. Now, we're thinking of switching web hosts (not domain registrar just the host) which means I have to change mydomain_a.com's nameservers to the new host. Will that affect or mess with the other 3 domains still pointing to ns1.mydomain_a.com and ns2.mydomain_a.com? Will that affect the private nameservers / glue records in anyway? Currently: domain: mydomain_a.com nameservers (GoDaddy): ns1.mydomain_a.com ns2.mydomain_a.com domain: mydomain_b.com nameservers (GoDaddy): ns1.mydomain_a.com ns2.mydomain_a.com After the Change: domain: mydomain_a.com nameservers (Other Host): ns1.some_other_host_ns.com ns2.some_other_host_ns.com This is my Question, Would this be affected? domain: mydomain_b.com nameservers (GoDaddy): ns1.mydomain_a.com ns2.mydomain_a.com

• How to set up a PC which can be booted from Linux AND Windows?

  - by Martin

  Our PC was running Windows XP up to know. It has become incredibly slow and I'm considering switching to Linux (Ubuntu?!) as a fresh OS. However, there are some applications we rarely use which run only on Windows and I also want to have the possibility to easily go back to the old system, if I should find during testing linux, that anything is missing or not available. So the idea is to install Linux on a new (second) hard drive and use the existing Windows XP from a virtual machine (converted by Paragon Drive Backup) in the transition time. We have a lot of data on the PC, tens of GBs of Photos (managed by Picasa), ... My questions: What could be the best way to setup the new hard drive? (Partitions) I assume that I can not access the Linux data from Windows but I could access (read/write) windows drives from Linux? Does anyone know good tutorials for this use case? What other things might I have to consider for transition Windows-Linux?

• How do I turn on bluetooth on a Dell Latitude E6410?

  - by Rob Stevenson-Leggett

  I have recently acquired a Dell Latitude E6410. It's great but I can't get Bluetooth to work. I have enabled bluetooth for the Wireless Switch in the BIOS. However whenever I try and install the bluetooth driver from the CD I get the message: Activate Bluetooth using the Wireless Switch. There is only a cancel button on this dialog. There is no bluetooth icon on any function key and I have tried switching the what I assume to be the Wireless Switch (the switch which controls wireless internet, on the right side of the laptop) to on and off positions to no avail. Does anyone know what the problem is?

• Is there a media player that allows me to group together radio streams which are just mirrors of the

  - by rakete

  I find it really annoying that for some radio stations, which have two or more servers to cope with the network load, there is not one single entry in amaroks playlist but two or more entries. This makes it hard to pick the radio station from the list I like to listen to because all the entries are always shown with the last played track as name, and even if I only have a few radio stations in my list there will eventually be many different entries. And, if I use the keyboard shortcuts to navigate the playlist I always have to remember that radio station X has for example four entries in the playlist, so I have to press the shortcut for switching tracks four times to actually switch the to the next station. Now, ideally I would like some solution for amarok, but if someone knows of another media player that does this or something I would appreciate that information as well.

• Stop UAC/Secure Desktop from dimming the screen

  - by Florian

  I like the concepts of UAC and the "Secure Desktop" in Windows 7, but I don't like the dimming of the Secure Desktop to prompt for Admin credentials (or OK button to get clicked). However, dimming goes so far that my monitor regularly goes into PowerSaver mode, which is annoying (as it takes another 10 seconds for it to wake up), and might harm the monitor: two weeks after switching from XP to Windows 7, my 30" monitor stayed black and it had to get replaced. The web is full of tips how to turn off dimming, but that will always also turn off the "Secure Desktop". Is there a way to present the Secure Desktop without dimming? Or with a different visual effect to show that it is the Secure Desktop? EDIT: To clarify, I'm not looking for a way to disable dimming by disabling Secure Desktop (as is done by lowering the UAC level). I want to keep both UAC and Secure Desktop.

• How to calculate required switch speed based on network usage?

  - by tobefound

  I have a 48 port HP Procurve Switch 2610 (J9088A) that can handle 13.0 million PPS (packets per second) and features wire speed switching capacity at 17.6Gbps. First off, what does that REALLY mean? Where do I start when trying to figure out if my office (with 70 employees) will be well setup with this switch? How to calculate through-put based on a user average load of X MB per day? 90% of the folks will only be sending email, access random websites, etc... the other 10% will be conducting heavier tasks like moving image files (10 MB) across network shares, constant external FTP streams through the switch to a server etc... Is this switch good enough?

• Is there a way to automate testing for a GNS3 network topology?

  - by Chedy2149

  I'm working on an MPLS backbone topology using GNS3, this topology includes configuration of several networking technologies such as IPv6, BGP, OSPF, IPv6 to IPv4 dynamic tunneling, MPLS based VPNs, MPLS based traffic engineering... So I'm a beginner with basic knowledge in networking (Ipv4 addressing, basic routing and switching) and I can't just easly test if my topology works or not, moreover fiddling with configuration I've noticed that sometimes when getting MPLS config right and missing BGP config all my topology is messed up. Given that I use Cisco 7200 series routers, is there any way to build a test harness for my topology in order to guarentee correctness with a single push button automated process?

• Is there a way to obtain a Dell server's RAID configuration/level using only winrm/wsman? (ESXi servers)

  - by EGr

  I've seen videos describing how to configure RAID using wsman/winrm commands run against a server's iDRAC, but I can't seem to find anything that will just give me the current configuration and RAID levels. Is this possible? What uri would I use? If it matters, this is being run against M610s. Edit: If there is an easier way to obtain this information by running a script against the iDRAC, I'm not opposed to switching my methods. EDIT: The server is running ESXi, so if there is a way to obtain this through the vSphere client or PowerCLI, I can do that too. Overall, I just need a way to obtain the RAID configuration for multiple servers without having to query against the actual server (eg: via the iDRAC).

• How do I turn off the click sound when closing a tab in chrome?

  - by nos

  Every time I close a tab in Chrome, it makes a click sound. How do I turn off that sound? I reported that issue back in Oct 2010. The problem doesn't appear on all clients and the reason is still unclear. Common attempts at solving the issue include simply turning off the sound in Windows. But I would prefer to solve the problem at the source. Why is Chrome even triggering that sound to be played? And why is it delayed? The problem would be far less annoying if the sound could easily be related to the action taken. Installing the Chrome Toolbox and muting all tabs has no effect on this issue. When switching to a different Chrome user profile, the new user profile does exhibit the same issue.
