• Are the ususal database performance-tuning tips invalide for a third-party app like Drupal

  - by Paul Strugger

  When you have a slow database app, the first suggestions that people make is to: Track the slow queries Add appropriate indexes In the case you are building your own application this is very logical, but when you use a CMS like Drupal, that are people have developed and tuned, is this approach valid? I mean, aren't Drupal tables already fine-tuned for performance? Even if I try to see which queries are the slow ones, what could I do about it? Re-write Drupal core?!?

• Does CakePHP have built-in functions to check for MySQL injections?

  - by vette982

  Does CakePHP check inputs to see if they are valid and not injections? If not, how would I go about implementing functions to check inputs? Most of Cake's processes are done behind the scenes, so I'm unsure of where I would do that.

• Why does isNaN(123.) return false?

  - by vivekraman

  Hi, Why does the Javascript function call isNaN(123.) return false? Is this a universally acceptable number or will it cause errors downstream? I'm validating whether a value is a valid decimal using isNaN along with split. Are there cross-browser issues with isNaN? Should I use a bespoke implementation? Thanks.

• C++ operator[ ] on integer litteral

  - by gregseth

  I found this piece of code: char a = 1["ABC"]; A few quick test led me to the fact it was the same than writing: char a = "ABC"[1]; Which seems far more logical to me. So my questions: Why is this notation valid? Is there any reason to write something that way?

• Java syntax of +

  - by Pindatjuh

  Why is the following syntax correct: x = y+++y; (Where it means y++ + y or y + ++y which both mean y * 2 + 1) But this is not valid syntax: x = y+++++y; (Which should mean y++ + ++y, which must mean y and increase y and then add ++y which increases y thus y * 2 + 2) Is there a reason for this?

• Accessing JAR resources

  - by Pablo Fernandez

  I have a jar file with resources (mainly configuration for caches, logging, etc) that I want to distribute. I'm having a problem with the relative paths for those resources, so I did what I've found in another stackoverflow question, which said that this was a valid way: ClassInTheSamePackageOfTheResource.class.getResourceAsStream('resource.xml'); Sadly this does not work. Any ideas? Thanks! PS: Obviously I cannot use absolute paths, and I'd like to avoid environment variables if possible

• Cancel the calculation if input-mismatch was found

  - by Lert Pianapitham

  Hallo everybody, i have programmed a sub procedure, that will be called in the main procedure (called by event of mainForm), to valid the inputs before the main calculation. now i'm searching for a method, how can i cancel the calculation and refocus the mainForm if some inputs mismatch. i think, it's unnecessary to use the Try-Catch statment to trap the error from calculation because i know what is its source and it should be prevented due to the code preformance. Has someone an idea to due with this? best regards Lert Pianapitham

• Java: Writing a DOM to an XML file (formatting issues)

  - by Vhaerun

  I'm using org.w3c XML API to open an existing XML file. I'm removing some nodes , and I'm adding others instead . The problem is that the new nodes that are added are written one after another , with no newline and no indentation what so ever. While it's true that the XML file is valid , it is very hard for a human to examnine it. Is there anyway to add indentation , or at least a newline after each node ?
