Linux Daemon Writing HOWTO

http://www.netzmafia.de/skripten/unix/linux-daemon-howto.html

Saved by uncleflo on January 4th, 2019.

A daemon (or service) is a background process that is designed to run autonomously,with little or not user intervention. The Apache web server http daemon (httpd) is one such example of a daemon. It waits in the background listening on specific ports, and serves up pages or processes scripts, based on the type of request. Creating a daemon in Linux uses a specific set of rules in a given order. Knowing how they work will help you understand how daemons operate in userland Linux, but can operate with calls to the kernel also. In fact, a few daemons interface with kernel modules that work with hardware devices, such as external controller boards, printers,and PDAs. They are one of the fundamental building blocks in Linux that give it incredible flexibility and power. Throughout this HOWTO, a very simple daemon will be built in C. As we go along, more code will be added, showing the proper order of execution required to get a daemon up and running.

Mozilla LDAP SDK Programmer's Guide/Searching the Directory With LDAP C SDK

https://wiki.mozilla.org/Mozilla_LDAP_SDK_Programmer%27s_Guide/Searching_the_Directory_With_LDAP_C_SDK

Saved by uncleflo on February 7th, 2018.

This section explains how to use the LDAP C API to search the directory and to retrieve entries. LDAP C SDK provides functions that allow you to search a directory and to retrieve results from the server. For example, you can send a search request by calling the synchronous ldap_search_ext_s() function or the asynchronous ldap_search_ext() function and the server sends back matching results.

Securely Hash Passwords with PHP

https://jonsuh.com/blog/securely-hash-passwords-with-php/

Saved by uncleflo on December 27th, 2017.

PHP 5.5+ now comes baked with a password_hash function to generate secure, one-way hashes along with a password_verify function to match a hash with the given password—If you’re a PHP developer, you should always be securely storing user passwords, no excuses. Developers have a huge responsibility when handling and storing user-sensitive information, such as a password. We should take extra precaution and the necessary steps to make sure the user’s data is safe and secure*. *Please keep in mind the following implementation is only part of the problem since it handles the data once the web server receives it; however, it does not address the other issue of securely sending the sensitive data over-the-air from the browser to the server, which is why a valid SSL certificate is necessary.

The RUST Programming Language

https://www.rust-lang.org/en-US/index.html

Saved by uncleflo on June 23rd, 2017.

Rust is a systems programming language that runs blazingly fast, prevents segfaults, and guarantees thread safety. If you haven’t seen Rust at all yet, the first thing you should read is the introduction to the book, The Rust Programming Language. It will give you a good idea of what Rust is like, show you how to install it, and explain its syntax and concepts. Upon completing the book, you’ll be an intermediate Rust developer, and will have a good grasp of the fundamental ideas behind Rust.

Many of users do not use powerful Maxima computer algebra system for systematic work, but for ad hoc algebraic calculations – equations, functions, matrixes, etc. only. To do this job, it is not useful to download the whole application from a web site.

JavaScript’s Apply, Call, and Bind Methods are Essential for JavaScript Professionals | JavaScript is Sexy

http://javascriptissexy.com/javascript-apply-call-and-bind-methods-are-essential-for-javascript-professionals/

Saved by uncleflo on February 22nd, 2015.

Functions are objects in JavaScript, as you should know by now, if you have read any of the prerequisite articles. And as objects, functions have methods, including the powerful Apply, Call, and Bind methods. On the one hand, Apply and Call are nearly identical and are frequently used in JavaScript for borrowing methods and for setting the this value explicitly. We also use Apply for variable-arity functions; you will learn more about this in a bit.

MySQL :: MySQL 5.5 Reference Manual :: 11.9 Full-Text Search Functions

http://dev.mysql.com/doc/refman/5.5/en/fulltext-search.html

Saved by uncleflo on February 22nd, 2015.

MySQL has support for full-text indexing and searching. Full-text searching is performed using MATCH() ... AGAINST syntax. MATCH() takes a comma-separated list that names the columns to be searched. AGAINST takes a string to search for, and an optional modifier that indicates what type of search to perform. The search string must be a string value that is constant during query evaluation. This rules out, for example, a table column because that can differ for each row.

Saved by uncleflo on February 22nd, 2015.

Basically, it's a simple tool that helps web designers find lighter and darker colors based on any color. Why is this necessary? Well, that takes a little more explanation. I built 0to255 to make my job easier. I'm a web designer who works with colors every day. Usually, I'll start with a color I want to use, then I'll manipulate it for various functions. For example, I might brighten a link in its hover state or darken a button's border to make it contrast with surrounding elements. Web designers do things like these several times an hour.

deparam function in JavaScript - opposite of $.param

https://coderwall.com/p/quv2zq/deparam-function-in-javascript-opposite-of-param

Saved by uncleflo on December 7th, 2014.

Often in Javascript you want to parameterize a map (hash|dictionary|whatever) to create a URL string, and jQuery has the utility function $.param to help you do so. But what happens when you want the reverse? jQuery doesn't have a "deparam" function. I bet other utility libraries do, and are probably more robust, but it's fun to write your own.

Blinn–Phong shading model - Wikipedia, the free encyclopedia

http://en.wikipedia.org/wiki/Blinn%E2%80%93Phong_shading_model

Saved by uncleflo on December 7th, 2014.

The Blinn–Phong reflection model (also called the modified Phong reflection model) is a modification to the Phong reflection model developed by Jim Blinn. Blinn–Phong is the default shading model used in OpenGL and Direct3D's fixed-function pipeline (before Direct3D 10 and OpenGL 3.1), and is carried out on each vertex as it passes down the graphics pipeline; pixel values between vertices are interpolated by Gouraud shading by default, rather than the more computationally-expensive Phong shading.

Compressible Aerodynamics Calculator

http://www.dept.aoe.vt.edu/~devenpor/aoe3114/calc.html

Saved by uncleflo on July 16th, 2014.

This calculator is intended to provide a faster more convenient alternative to printed tables and charts (e.g. NACA Report 1135). The core of the code was written in Javascript by William Devenport at the Aerospace and Ocean Engineering Department, Virginia Tech. Five sets of relations are included; The relations themselves are taken from standard aerodynamics texts. Symbols have their usual meanings. 'Gamma' and 'rho' are substituted for the corresponding greek letters denoting the ratio of specific heats and density. Subscript 'o' is used to refer to stagnation or total conditions, superscript '*' refers to sonic conditions.

(See this question for why I must use application/json: http://stackoverflow.com/questions/2792603/aspnet-mvc-why-is-modelstate-isvalid-false-the-x-field-is-required-when-that)

How can I make $.post() send contentType=application/json? I already have a large number of $.post() functions, so I don't want to change to $.ajax() because it would take too much time

Wordpress Codex Function Reference

http://codex.wordpress.org/Function_Reference/

Saved by uncleflo on May 9th, 2013.

The files of WordPress define many useful PHP functions. Some of the functions, known as Template Tags, are defined especially for use in WordPress Themes. There are also some functions related to actions and filters (the Plugin API), which are therefore used primarily for developing Plugins. The rest are used to create the core WordPress functionality. Many of the core WordPress functions are useful to Plugin and Theme developers. So, this article lists most of the core functions, excluding Template Tags. At the bottom of the page, there is a section listing other resources for finding information about WordPress functions. In addition to this information, the WordPress phpdoc site details all the WordPress functions by version since 2.6.1.

How to create a random string using PHP? - Stack Overflow

http://stackoverflow.com/questions/853813/how-to-create-a-random-string-using-php/853870#853870

Saved by uncleflo on February 4th, 2013.

The basic algorithm is to generate <length> times a random number between 0 and <number of characters> − 1 we use as index to pick a character from our set and concatenate those characters. The 0 and <number of characters> − 1 bounds represent the bounds of the $charset string as the first character is addressed with $charset[0] and the last with $charset[count($charset) - 1].
