• Use XAML data binding to bind each end of a Line to the center of two shapes on a Canvas

  - by spoon16

  I have a Canvas in Silverlight with two ellipses on it. The ellipses are animated via events in the code behind. I have added a line two the canvas and I would like each end of the line to be bound to the center of each ellipse. Is it possible to do this in XAML databinding or will I have to manually move the end of the line around in code?

• MySQL, if a value is in one of two columns, return the value from the other one

  - by erikric

  Hi, This might be an easy one, but I'm not really experienced with sql. I have a table with two user_id columns, user1 and user2. This table contains some compared values between the two users. I want to send in an user id, and return all the id's from the other user when the sent user is either user1 or user2. I guess some sort of if test would do the trick, but I don't know how to do this in SQL. Cheers

• How can I diff two files and report the section the diff occurs in?

  - by Les

  I have two text files with several sections in them. Each section has has a header with the section name (grep can extract all the section names without extracting anything else from the file). How can I report the differences between the two files AND report the section that the difference occurs in? I would also need to be able to report added/missing sections. Ideally, identical sections would not be mentioned in the report at all.

• Algorithm to add two digits to the end of a number to calculate a specific modulus?

  - by Jim

  So, lets say I have a number 123456. 123456 % 97 = 72. How can I determine what two digits need to be added to the end of 123456 such that the new number % 97 = 1? Note--it must always be two digits. For example, 12345676 % 97 = 1. In this case, I need to add the digits "76" to the end of the number. (This is for IBAN number calculation.)

• Name that blog entry - Modelling changes over time with two db columns only.

  - by disown

  I vaguely remember reading a blog entry (written by a well-known blogger I think) about how to model price changes over time, and that you could model most changes by saving two dates only (two columns in a db). The blog talked about prices on a website changing over time and how you could figure out the right price to charge knowing only when the purchase had been made. Very vague, I know, but my google-fu is failing me, everyone at IRC are busy talking about other stuff and I don't know what to do! :)

• Can two threads of the same process produce the same GUID?

  - by mark

  Dear ladies and sirs. If two threads in a process generate a new GUID concurrently using .NET API (Guid.NewGuid()) is it possible that the two GUIDs will be identical? Thanks. UPDATE I want to get practical. I know that it is widely assumed that GUIDs are unique for all practical purposes. I am wondering if I can treat GUIDS produced by the different threads of the same process in the same manner.

• Doctrine 1.2: Can a model have two instances of the sluggabl behavior?

  - by prodigitalson

  I dont see any direct mention on using multiple slugs (or any behavior for that matter) for single model. Is there a way to use the sluggable behavior to generate two separate slugs for a model? For example i need to generate two slugs for every record a product_id consisting of a slugified company name and sku and a distributor_id consisting of a different slugified company name. Obviously i could write this myself fairly easily, im just wondering if this can be done quickly with Sluggable.
