• why do I have to commit explicitly when doing an UPDATE

  - by Tshepang

  Here's my code: import cx_Oracle conn = cx_Oracle.connect(usr, pwd, url) cursor = conn.cursor() cursor.execute("UPDATE SO SET STATUS='PE' WHERE ID='100'") conn.commit() If I remove the conn.commit(), the table isn't updated. But for select statements, I don't need that conn.commit(). I'm curious why?

• Why should I use "Web 2.0"-style URLs?

  - by hydrapheetz

  In short, why use something like http://stackoverflow.com/badges/6/supporter instead of something "simpler" (and subjectively, at that) like http://stackoverflow.com/badges/6/. Even on my own site I've just been using /post/6/ to reference posts (by IDs, even though I still store a slug.) Instead of /post/6/small-rant-on-urls, and in some cases, they can get even more absurd, much more so than is really necessary.

• Why does Code::Blocks constantly changes my language?

  - by Yakov Lipkovich

  On my there are two set languages, which are English and Russian, and English is the default set language. Yet every time I leave Code::Blocks and click on the window again, the program automatically changes the language to Russian, which not only is it annoying, but it doesn't make much sense. Does anyone have any idea why it's going on and how to get rid of this pest? So far that's the best C++ IDE I have found and I don't want to ditch it due to such a nasty annoyance.

• Why is this <p> expanding the whole page?

  - by George Edison

  If you visit this page and shrink your browser window, you will see my problem. [If you want to open the page in a new window, just hold down shift when you click the link.] The answers to the question extend beyond the page margin instead of wrapping. I have spent the last half hour working with Chrome's Inspector and Firefox's DOM inspector - all to no avail. I just cannot figure out why it's doing this.

• Why does Java uses heap for memory allocation?

  - by happysoul

  I just read this statement in a java book saying Objects in java reside on a heap. Is a heap used because it is the best way to store data and retrieve data fast ? I only have an idea about data structures being a beginner. I mean why not stack or something else ?

• Why toInteger :: Int -> Integer is lazy?

  - by joppux

  I have the following code: {-# NOINLINE i2i #-} i2i :: Int -> Integer i2i x = toInteger x main = print $ i2i 2 Running GHC with -ddump-simpl flag gives: [Arity 1 NoCafRefs Str: DmdType U(L)] Main.i2i = GHC.Real.toInteger1 Seems that conversion from Int to Integer is lazy.

• Why isn't LISP more widely used?

  I've heard a lot of people espouse the capabilities of LISP and its omnipotent macros. If LISP is such a great language, why isn't it being adopted more? What problems is LISP facing that is holding it back from (re)emerging as popular language? Is it something about LISP itself ("those brackets!" isn't the answer, is it?!), or its competitors (e.g. the dominance of Java, .NET)?
