What if someone were to change, say, 'Business' to 'Main' then I would have to refactor every SQL function and likely the app too... whereas if it's 1 then no change other than what it displays in the result set...
Actually. this sounds really stupid @mjolka, but how am I supposed to write a unit test that fails when my compiler is complaining that the function doesn't return a value on all paths.
i believe that's fine. i think with TDD, it doesn't matter if some tests pass, you just want at least one to fail
so we write Test12False, and write the simplest version of IsFactor that will compile: the return false version. great, we have a passing test. now we write Test12True, and see that it fails -- this means we need to fix IsFactor

So I am trying to do a pig latin project, I have it translating and adding etc, but I am running into some case problems.
when I type CASE it should translate to ASECAY but instead i am getting Asecay, any help on how to fix it?
Also how do i make it not translate words that contain numnbers/symb...
I have heard that larger answers can tell others that an ideal review should be long, and not everyone would like to take the time to write a long review. Plus, with shorter answers, there is room for multiple answers, which is a good thing.

Goodnight @chillworld. Talk to ya in about 5 or 6 hours.
Yeah @Jamal. It's broken.
Your program is not correct, so don't try to make it faster. There's no point in writing a fast program that gets the wrong answer. Try it with a smaller number. What does your program say the largest prime factor is of 12? (Hint: the correct answer is 3.) Until you can write a program that gets the correct answer, don't try to speed it up. — Eric LippertMar 20 '12 at 20:47
@Phrancis Yes, it's overkill, for the reasons that cimmanon and I mentioned. Use an ENUM for the email type, or as cimmanon suggests, just make a table with one column: Email_Type TEXT PRIMARY KEY. The Email_Type_Id, as you've written it, will just be an annoyance when you write your app.
There is no difference, under the hood it's all varlena.

when i type in a+b+c for an infix expression, I receive abc++ as my postfix expression and +a+bc for my prefix expression. However it is supposed to be ab+c+ for postfix and ++abc for prefix. I only receive the incorrect results when i am not using parenthesis. Any suggestions?

Make sure you do a full clean/revuild, we have, a couple of times, fallen victim to a class that was compiled with the old package, and then with the new package as well, and both were in the dev environment, and it took a full clean build to fail before we realised.
It just literally merged the new package name randomly inside the old import
I've cleansed and rebuilt everything 10 times, should that be enough?
The sad thing about package names is that higher-ups really are not going to care that you spent half an hour changing all of them, but if you only have one wrong package name you'll get verbally killed.
And of course it's in Scala, and I do a lot more than just logging. There's an actor based event dispatcher, actor based TCP/IP communications, and a some other misc stuff.
> I think that the use of a LinkedList is not optimal. In every invocation of drainSource you potentially add a new DataBlock ant the end of the linked list; this has performance O(n) (length of the list). I propose to use a Vector instead of the LinkedList.
Isn't it quite normal for a linked list to internally hold a pointer to the last element?
