• Does Shoes have a list view control?

  - by Jim

  I was taking a look at Shoes which seems like a very nice tool for quick GUI applications. The common elements/controls, however, don't seem to include the equivalent of a list/report view (e.g., ListView in Windows, NSTableView in OS X). Did I just miss this, or does it not (yet) exist?

• What are guard methods/classes?

  - by Paul Sasik

  i just noticed the guard method/class mentioned in this question and i don't really get the concept from the answers. And alas, Jon Skeet's link to an MS site never loaded. A few quick Google searches seemed to yield only products, not software engineering concepts. Any explanation and/or samples would be appreciated. (Especially from the .Net side of things.)

• Why is my ASP.NET app slow the first time after building a class library?

  - by David

  Hi all I've got a web app solution containing a class library project. Whenever I rebuild the class library and then refresh the page, it takes ages the first time, and is then quick again subsequently. It's almost as if the newly rebuilt dll is having to 'bed in' to the app. Can anyone tell me what's really going on behind the scenes? Thanks David

• Cache SHA1 digest result?

  - by johnathan

  I'm storing several versions of a file based on a digest of the original filename and its version, like this: $filename = sha1($original . ':' . $version); Would it be worth it to cache the digest ($filename) in memcache as a key/value pair (the key being the original + version and value the sha1 hash), or is generating the digest quick enough (for a high traffic php web app)? Thanks, Johnathan

• EC2 - taking an EBS snapshot, saving to S3, and then launching instances from S3

  - by git-noob

  I like the convenience of taking an AMI snapshot - but ideally I do no want to pay for the volume to be attached to my running instance. Is there a way to save a snapshot instance to S3 and then launch from S3 without attaching a volume to the running instance - gaining the convenience of snapshots - without the running costs?

• Stack overflow code golf

  - by Chris Jester-Young

  To commemorate the public launch of Stack Overflow, what's the shortest code to cause a stack overflow? Any language welcome. ETA: Just to be clear on this question, seeing as I'm an occasional Scheme user: tail-call "recursion" is really iteration, and any solution which can be converted to an iterative solution relatively trivially by a decent compiler won't be counted. :-P ETA2: I've now selected a “best answer”; see this post for rationale. Thanks to everyone who contributed! :-)

  Is it possible to use PHP magic methods (specifically __get()) outside a defined class? I'm wanting to use it in a configuration file for quick loading. The configuration file has a single array, $config, with many keys. Therefore, I'd like to override __get() to return the key in the array.

• PDO/Oracle vs OCI

  - by jarcoal

  The company I work for currently uses some basic functions to abstract the OCI libraries as a means for DB connectivity. We're considering switching to PHP's PDO object, but from some quick searches, it looks like the Oracle driver is a bit less mature than the other PDO drivers. I would appreciate some pro/cons for PDO/Oracle from anyone who has used it in a production environment. Thanks!

• Short circuiting statement evaluation -- is this guaranteed? [C#]

  - by larryq

  Hi everyone, Quick question here about short-circuiting statements in C#. With an if statement like this: if (MyObject.MyArray.Count == 0 || MyObject.MyArray[0].SomeValue == 0) { //.... } Is it guaranteed that evaluation will stop after the "MyArray.Count" portion, provided that portion is true? Otherwise I'll get a null exception in the second part.

• Evaluating software estimates: sure signs of unrealistic figures?

  - by Totophil

  Whilst answering “Dealing with awful estimates” posted by Ash I shared a few tips that I learned and personally use to spot weak estimates. But I am certain there must be many more! What heuristics to use in the scenario when one needs to make a quick evaluation of software project estimate that has been compiled by a third-party (a colleague, a business partner or an external company)? What are the obvious and not so obvious signs of weak software estimates that can be spotted without much detailed knowledge of task at hand?

• Comparing file contents in F#

  - by Bartosz Milewski

  I wrote a quick and dirty function to compare file contents (BTW, I have already tested that they are of equal size): let eqFiles f1 f2 = let bytes1 = Seq.ofArray (File.ReadAllBytes f1) let bytes2 = Seq.ofArray (File.ReadAllBytes f2) let res = Seq.compareWith (fun x y -> (int x) - (int y)) bytes1 bytes2 res = 0 I'm not happy with reading the whole contents into an array. I'd rather have a lazy sequence of bytes, but I can't find the right API in F#.
