• EF exception: Could not find file CodeGenerationSchema.xsd

  - by DK

  I'm using Entity Framework for a new project (VS 2008, .net 3.5 sp1) and "reasonably happy" with it, especially compared to dataset-based solutions. One of recurring annoyances is "Could not find file CodeGenerationSchema.xsd" exception during application startup. Exception seems to re-appear rather frequently after changes to the model. Googling gives temporary and strange workarounds for this error: Delete .suo file, or Set Options Debugging General Enable Just My Code = On May be someone have more permanent, straightforward fix or can explain the reason of this issue.

• How can I remove the DRM from books I have purchased for my Kindle? [closed]

  - by Jeremy Banks

  How can I the remove DRM from books I have purchased for my Kindle? A solution that works on Mac OS X and/or Linux would be ideal, but a Windows-only solution is also acceptable. Moral aside: I do not plan to share or pirate books; I am very happy with the Amazon Kindle store and have purchased more books from there since getting my Kindle a month ago than I had in the previous two years. However, I do not feel comfortable keeping them in an encrypted format that only a single company's software will allow me to access. I may also want to convert them into a format for other readers in the future, which is not possible without first removing the DRM.

• breaking mdadm raid and moving to NTFS

  - by daveyt

  I'm running Ubuntu 8 something and my data is on a mirrored pair of 1TB disks formatted as ext3, and the RAID is via mdadm. I want to move to Windows 7 (yeah yeah I know but Linux aint doing it for me at the moment) and migrate the disks to NTFS. My plan is: Break the MDADM RAID (by failing one disk logically) Format the 'failed' disk as NTFS Copy data from the RAID array to the NTFS disk (dont care about perms) Install Windows, (new separate non RAid disk) and my data disk is available. I've researched this and it seems the easiest way. I dont have another disk to back up to so I think this is my only way. Can anyone see a better/easier way?

• Best configuration and deployment strategies for Rails on EC2

  - by Micah

  I'm getting ready to deploy an application, and I'd like to make sure I'm using the latest and greatest tools. The plan is to host on EC2, as Heroku will be cost prohibitive for this application. In the recent past, I used Chef and the Opscode platform for building and managing the server infrastructure, then Capistrano for deploying. Is this still considered a best (or at least "good") practice? The Chef setup is great once done, but pretty laborious to set up. Likewise, Capistrano has been good to me over the past several years, but I thought I'd take some time to look around and seeing if there's been any landscape shifts that I missed.

• How to search for one of two similar strings in Vim?

  - by Nathan Long

  This is a pretty simple regex question, I think. In Vim, if I want do a search that matches planA or planB, I know that I can do this: /plan[AB] This works because the regex allows for either A or B as its set of characters. But how can I specify one of two complete strings? For example, to match both planetAwesome and planetTerrible, this doesn't work: planet[Awesome|Terrible] ... because it's looking for planetA or planetw or planete, etc. Nor does this: planet['Awesome'|'Terrible'] This will match both of these, along with planetAnythingHereAsLongAsItsJustLetters: planet\([a-zA-Z]*\) But how can I match only strings that match planetAwesome or planetTerrible exactly?

• NAT and ISP Subnet when load balancing on pfsense?

  - by dannymcc

  I have a pfsense box that I'm trying to plan the configuration for. I am going to be load balancing two ISP's, each with their own /29 static IP subnet. The question I have is in relation to the way those IP's are associated with workstations on the local network. Currently I have some workstations with local (192.168.1.0/29) IP addresses, and other more complicated workstation setups have their own public IP address. Some of the more complicated systems have a NAT 1:1 configuration where I forward a public IP address to a local IP address. Others however are directly on the ISP subnet and cannot be seen on our local network. Is this configuration possible with pfsense? If so, what terms should I be looking through the documentation for? Here is a simple/brief diagram of what I am trying to achieve.

• Anyway to backup nginx before recompiling

  - by JM4

  I am looking to install the HttpGeoipModule for NGINX but learning I have to recompile the entire thing from source in order to do so. I have a new Media Temple DV 4.0 server and that comes with nginx v 1.3.0 stock and have never had to recompile from source before and a bit nervous to make changes without being able to revert to a previous state in the event something messes up (that and the fact it is affecting a live server so no idea what downtime is). My plan was to copy all the existing modules used (nginx -V to list them all and copy the modules already compiled). Then rebuild from source with the copied info above and including the ./configure --with-http_geoip_module reference. Is is possible to backup the existing nginx configuration in the event something goes wrong?

• How to bridge git to ClearCase?

  - by Bas Bossink

  I've recently used git svn and enjoyed it very much. Now I'm starting a new project at a different customer. At that site the SCM of choice is ClearCase. I haven't found a baked equivalent of git svn for ClearCase. Is there anybody who has tried to use git locally as a front-end to ClearCase using some tricks, configuration or scripting with any measure of success? If so can you please explain the method used?
