• Interpreter more strict

  - by pacopepe

  Hi, Today, i lost a lot of time fixing a stupid error in my code. Very simplified, the problem was this: def f(): return 2 2 == f I forgot to write the parenthesis in the sentence, so I compared a pointer function with a number. Ok, my question: Is there any way to change the interpreter to be more stricted with the code? Show more warnings for example... Thanks ^^

• How to block writing in pipes, until the read has taken place ? (in C)

  - by user492194

  Hi everyone :) I'm currently working on some C program, and I'd like to know if there's any chance to block writing in the writer process (until the read is done) ? i.e. I have 3 pipes between the parent process and the children processes (the parent writes and the children read), I'd like to let the parent to write only to the process that finishes its reading :) I hope it's clear.. Thanks in advance.

• Obtaining standard port for arbitrary protocols in PHP

  - by Trott

  I'm looking for a function that will accept a string representing the scheme portion of a URL (e.g., "http", "https", "ftp", etc.) and return the standard port. It might be used like this: echo get_port_from_protocol("http"); // 80 As a last resort, I suppose I could write something to parse through /etc/services (assuming I only need to run under UNIX-like operating systems). But surely there must be something built-in to PHP, no?

• Change query to use a LEFT join

  - by Craig

  I have a query which is failing, as it needs to be using LEFT JOIN, as opposed to the default INNER JOIN used by the 'join' syntax: var users = (from u in this._context.Users join p in this._context.Profiles on u.ProfileID equals p.ID join vw in this._context.vw_Contacts on u.ContactID equals vw.ID orderby u.Code select new { ID = u.ID, profileId = p.ID, u.ContactID, u.Code, u.UserName, vw.FileAs, p.Name, u.LastLogout, u.Inactive, u.Disabled }).ToList(); How would i re-write this so that is utilises a LEFT join?

• Javascript Date: Ensure getMinutes(), getHours(), getSeconds() puts 0 in front if necessary

  - by Mega Matt

  Hi all, Looking for a creative way to be sure values that come from the getHours, getMinutes, and getSeconds() method for the javascript Date object return "06" instead of 6 (for example). Are there any parameters that I don't know about? Obviously I could write a function that does it by checking the length and prepending a "0" if need be, but I thought there might be something more streamlined than that. Thanks.
