• Rails migration to add boolean column to Postgres on Heroku

  - by pmc255

  I'm trying to execute a simple Rails migration to add a boolean column to an existing table. Here's the add_column call: add_column :users, :soliciting, :boolean, :null => false, :default => false However, after the migration runs (successfully, with no errors), I don't see the new column. If I go into the console and list the columns on the User table, for example, with this command: >> User.columns.each { |c| puts "#{c.name} : #{c.type}" } All the other columns show up, but not the one I just added with the migration. What's even more strange is that looking up a random user object yields the Postgres version of booleans (Ruby strings) >> User.find(1).soliciting => "t" However, the existing boolean columns all show up with standard Ruby boolean values of true and false. What's going on here? Is the migration actually complete? Why doesn't the column show up, yet is accessible in the model objects?

• Mouse wheel scrolling in less and vim using urxvt

  - by Adam Batkin

  I have started working with rxvt-unicode (aka urxvt) but found an issue with mouse-wheel scrolling, as compared to gnome-terminal and konsole. The mouse wheel works fine for going through the scrollback buffer, but it doesn't work for automatic scrolling in less/most or vim (though in vim, setting mouse=a makes it work, but in a very different way, which I don't have to do with gnome-terminal/konsole). Is there a way to make urxvt behave like gnome-terminal and konsole when in less and vim where the mouse wheel Just Works?

• Multi-core DVD ripping/encoding on the Mac

  - by Paul D. Waite

  A friend of mine likes ripping DVDs to his Mac. He’s currently on an ancient machine, and is about to upgrade to either a MacBook Pro or an iMac. Just wondering if any of the Mac DVD ripping software will rip faster on the iMac (thanks to its four cores), as opposed to the MacBook Pro (a measly two cores)? Or is DVD ripping not that sort of task?

• Internet Explorer stores working data under %TEMP% instead of normal locations

  - by SWB

  Internet Explorer normally stores its working data in various special locations. For example: Cookies - %APPDATA%\Microsoft\Windows\Cookies History - %LOCALAPPDATA%\Microsoft\Windows\History Cache - %LOCALAPPDATA%\Microsoft\Windows\Temporary Internet Files However, for some reason, Internet Explorer occasionally stops using the normal locations and instead creates new folders under %TEMP% and/or %TEMP%\Low for this data. For example: Cookies - %TEMP%\Cookies %TEMP%\Low\Cookies History - %TEMP%\History %TEMP%\Low\History Cache - %TEMP%\Temporary Internet Files %TEMP%\Low\Temporary Internet Files Why does Internet Explorer do this, and how can make it use the normal locations again?

• Need some help trying to rip a CD using Windows Media Player on XP

  - by Pure.Krome

  Hi folks, i'm trying to rip a CD using Windows Media Player 11 on XP ... and the destination folder is in the ALBUM NAME. Now, i can't see HOW it can rip to a new folder, named after the album. As far as I can tell, it's named by the Artist Name .. which sorta sucks for me. So, is there a way I can rip a CD with WMP11 that puts the songs into a new/existing folder which is the name of the Album? cheers :)

• XBMC: Viewing podcasts in 'Library Mode'

  - by greggannicott

  I'm having a great time getting to know XBMC, and so far for the most part I've been really happy with the results. I was chuffed when I followed the advice on this SU post and added TWiT as a video podcast with ease. However, when I go into Library Mode I can no longer access the podcasts I've added. I realise that one simple work-around is to come out of Library Mode to view podcasts, but in order to keep everything as simple (and appealing) to my wife as possible I'd rather remain in Library Mode so that on the rare occasion she wants to watch a DVD, she can do so without my help. Does anyone know a way to display podcasts in library mode? If this isn't possible is there a more elegant solution/work-around to going back and forth between library mode? Many thanks.

• Biztalk Server 2006 64bit problem

  - by WtFudgE

  Hi, I am trying to install a 64-bit biztalk server 2006. However when I start my installation it asks if I want to get my .cab file from the internet or install it manually etc. Because of internet security issues here at our work we can't get it from the internet directly. So I downloaded it manually: BtsRedistW2k3EN64.cab, to be exact. However when I try to install this it complains about: This installation package is not supported by this processor type. Contact your product vendor. I opened the cab file and found out that the file: SQLServer2005_ADOMD.msi was apparently the problem. So I thought I'd install the 64bit version of this msi then: SQLServer2005_ADOMD_x64.msi, however I get the same error. So atm I'm pretty stuck. Anyone have any ideas? Thanks a lot

• Windows 7 Backup - Does the "system image" include all the files on my drive?

  - by Vaccano

  I have a new Dell Laptop that I have setup the way I like it. I want to use Windows 7 to do a backup and then restore that backup on a different hard drive (solid state). When I setup the backup info (manually) for Windows 7 Backup there is a little checkbox at the the bottom that says: Include a system image of drives: RECOVERY, OS (C:) I can also select to backup all my data on the C: drive (the only hard drive I have anything on) as well as some libraries (which are on my C: drive so no point in selecting those). The question I have is, does Windows 7 Backup just somehow know what needs to be restored (ie program files and Windows and the registry ....? Or is it really making a full restorable copy of the C: drive? (If the later is true then I don't need select the C: drive to be "backed up" if I don't plan to access the files except by restoring them right? (Because the system image will already have it all.)) So, which way is it? What is saved in the System Image?

• D-LINK 2450U DSL router: Port forwarding forwading to the modem itself, not the specified IP

  - by axk

  I found a similar question but it has no satisfactory answers. I have a D-LINK 2540U DSL router. It has a basic port forwarding(under DNS - Virtual Servers) configuration in the administration panel where you specify: external port range, protocol, internal port range, server IP address and it is supposed to forward that port to that IP address. When I first set it up for a Real VNC connection it worked fine, just as I expected. Then I added a DynDNS configuration entry in the router's 'Dynamic DNS' section and added an additional SSH (22) forwarding rule. The SSH forwarding also worked fine (now with the dynamic hostname, but I suppose it doesn't make any difference as far as SSH is concerned). Then I removed the SSH rule and after that the VNC forwarding stopped working with the VNC client failing to connect (I have tried to connect with telnet and it also failed to connect, so it wasn't a VNC problem). After adding a rule for port 80 it turned out it would forward on port 80 though not to the specified server IP but to the modem itself. At least it is what it looks like, because it gives me the administration panel when I connect to my external IP (both using a browser and plain telnet in which case I can see that it is mini_hhtpd sitting on the port, which is obviously the modem's administration panel). Have anybody encountered a similar problem with port forwarding? I have tried to do a reset through the administration panel and to restore a backup of the settings made before I started playing with port forwarding, but it didn't help. Should I do a 'hard' reset with the button on the modem? Is it any different from the administration panel's reset (Restore default)?

• Installing sun-java6-jdk with apt-get on Ubuntu 10.04

  I have followed the instructions on numerous pages, such as this, which say to run the following commands: sudo add-apt-repository "deb http://archive.canonical.com/ lucid partner" sudo apt-get update sudo apt-get install sun-java6-jdk However, when I do this I still get the following error: me@mycomputer:~$ sudo apt-get install sun-java6-jdk Reading package lists... Done Building dependency tree Reading state information... Done Package sun-java6-jdk is not available, but is referred to by another package. This may mean that the package is missing, has been obsoleted, or is only available from another source E: Package sun-java6-jdk has no installation candidate I realize Java is available from many other sources, but for reasons that I can't get into here I must use this specific version. What can I do to get this installed?

• Should I use 802.11n with a 15 Mbps ISP (Comcast Cable)?

  - by stackoverflowuser2010

  I currently own a LinkSys-WRT54GL 802.11a/b/g wireless router, and my ISP is Comcast Cable providing me with 15 Mbps (that's bits per second, I believe) download speed. I am wondering if there is any benefit with using an 802.11n wireless router to access the Internet? The maximum theoretical speed of the WRT54GL router is 54 Mbps (802.11g), which is faster than the 15 Mbps provided by my ISP. I know that 802.11n has a max bandwidth of 300 Mbps, and it would help for intra-house transfers, such as streaming video from one computer to another. But is there any benefit to 802.11n for Internet activity, such as web browswing, gaming, and streaming video from Netflix?

• Can't Install Windows 2008 R2 on Lenovo Laptop With SSD

  - by Ben

  I am trying to install Windows Server 2008 R2 on a new Lenovo X201 or T410 laptop. Setup halts with the following pop-up: A required CD/DVD device driver is missing. If you have a driver floppy disk, CD, DVD, or USB flash drive, please insert it now. Note: If the windows installation media is in the CD/DVD drive you can safely remove it for this step. The CD drive is obviously working, as it's booting from CD to get to this point. The only thing I can think is that it is to do with the fact they have SSD disks in - but that's just a guess. (Edit - One extra thing that may or may not be relevant: it's the 64 bit version of Server 2008 R2)

• Ubuntu and Belkin N150 f6d4050 Wireless USB adapter v2

  - by Andrew

  I'm new to Ubuntu, and I'm trying to get my Belkin USB adapter to work. There are plenty of discussions out there already about this, but none really helped me out. Here's what I've done - Installed ndiswrapper Installed ndisgtk Installed the driver (rt2870.inf) via ndisgtk ndisgtk reported that the driver was installed and the hardware was present. The green light on the adapter is solid green, which I assume means that Ubuntu is aware of it's presence. However, when I click the little wireless symbol at the navigation bar, there's no option to choose my adapter (assuming that it's supposed to show up there...) My adapter version is F6D4050 - Where do I go from here? I'm a Ubuntu newb, so speak slowly. :P lsusb - andrew@ubuntu:~$ lsusb Bus 002 Device 003: ID 046d:c517 Logitech, Inc.

• DNS problems with Google on Windows 7

  - by awishformore

  Hello dear superuser community. I had no idea where to post this because it is a problem that completely baffles me. I have a lot of experience with network configuration, but I am completely out of ideas on how to fix this. I have a Fritz!Box branded router on my ISP 1&1 in Germany. My computer is connected to it with a normal Ethernet cable. I always manually set my IP on the computer and use the Google DNS servers for name resolution. I also tried OpenDNS and the result is the same. With that configuration the following happens: Google search responds with big delay Gmail, Google Calendar & Google Drive requests time out the majority of the time In order to troubleshoot, I set the network connection to DHCP for both IP & DNS. At that point, what happens is the following: Google search times out most of the time Gmail, Google Calendar & Google Drive work most of the time Sometimes, it happens that the sites that time out will come up, but weirdly enough, the pictures on the buttons will be missing. For instance, the magnifying glass on Google will be gone or the circle arrow on Gmail (but all buttons of course). All other websites load just fine - and very quickly. All other network functionality is completely unimpacted. The behaviour of fixed IP & Google DNS vs automatic IP & DNS is easily reproducible. I am going crazy trying to fix this as I have no idea what the hell is going on at this point. Here a list of the things I have tried thus far: Flushed the DNS Tried on different browsers (Works fine on my laptop by the way) Tried disabling Teredo & IPv6 stack Emptied all caches Checked the HOSTS file Rebooted the router Reset the router Reinstalled the network adapter Tracert displayes normal route until timing out at one point Ping usually doesn't work for the unreachable sites either Ran both complete Norton 360 & Kaspersky 2012 scan Ran Kaspersky Virus Removal Tool in safe mode Tried connection in safe mode & networking enabled If you have any ideas, please let me know. I'm getting desperate...

• my Website loss packet in 70% countries, how can i dertermine why its loss packets?

  - by user2511667

  I checked my website on google page speed tester, it show result 90/100. I checked my website on pingdom it shows good result there. When i check my website in cloudmonitor.ca.com, it shows good result in 30% countries and all other countries it show packet loss (100%) How we can determine why my website has packet loss? And what is its solution? Is this problem from my server or from my website? I created new html blank page and set it too my index page, after I tested, it still shows packet loss, guess this means the problem is not in my website. Here is live result When I visit my website in browser, website is working fine. But when i test my domain or IP 198.178.123.219 in command Prompt it shows "Request time out" Why time out in command prompt?

• iPhone apps causing battery to drain out

  - by saurabh

  Hi, Recently my iPhone battery started to discharge in just one day. I do not use my iPhone much (less than 1 hour a day). and then while discussing it with couple of colleagues, I heard that there are some apps which even if installed on your iPhone can cause your battery to drain out faster. It does not matter if you are not using those apps, only having them installed was enough to cause battery drain. I have heard this from couple of my techie friends as well and thus had to put some credibility to it. Being an iPhone developer, I don't think that is possible. Do you think if this is possible for an app to cause battery drain just by being installed there on iPhone?

• Linux accessibility: Slow Keys causing duplicate key strokes

  - by skypanther

  I'm exploring the accessibility features within Gnome and having trouble with Slow Keys. My input is always doubled. Press a key briefly and I get nothing as you'd expect. Press just a bit longer and which ever key I'm pressing is input twice. Hello becomes HHeelllloo. I'm running Debian Lenny 5.0.6, kernel 2.6.26-2-686, GNOME Desktop 2.22.3 running within a VirtualBox session. I did some googling and didn't find others having similar troubles. Maybe it's a vbox thing? Any ideas how to fix this so I don't get the duplicates? It makes it impossible to log back in when the screen lock kicks on!
