I'm horrible at finding colors that look good together, so I cheat and use pictures from nature that are mostly the color I want (say, green) and then I use [this website](http://www.degraeve.com/color-palette/) to pull out the main color scheme. Generally nature does a pretty good job of setting its own nice color sch...

Note that there is a difference between && and & regarding how much of your expression is evaluated. && is known as a short-circuited boolean AND, and will, as noted by others here, stop early if the result can be determined before all the sub-expressions are evaluated. & is known as a logical bitwise operator and wi...

Three branches just sounds like extra work. Environmental differences can be handled by having different versions of the relevant files in the trunk. i.e. database.yml & database.yml.prod. The deployment process should be environmentally aware and simply copy the per-environment files over the default ones.

I think that once he has the basics (variables, loops, etc) down you should try to help him find something specific that he is interested in and help him learn the necessities to make it happen. I know that I am much more inclined and motivated to do something if it's of interest to me. Also, make sure to let him str...

In my experience, the only time this really adds business value is when there is a need for 100% support for accessibility. When you have users who are visually impaired and/or use screenreaders to view your site, you need to make sure that your site is compliant to accessibility standards. A menu should be a list ...

I realise this question has already been answered, but I'd like to throw in another bit of information which is related to the topic. In languages, like C++, where you can actually overload the behaviour of the && and || operators, it is highly recommended that you . This is because when you overload this behaviour, y...

I've been developing a site using ASP.NET MVC, and have decided to use the new SQL Server 2008 `FILESTREAM` facility to store files 'within' the database rather than as separate entities. While initially working within VS2008 (using a trusted connection to the database), everything was fine and dandy. Issues arose, h...

One other thing I just remembered, you can assign a different stylesheet to a page for printing vs. display. In addition to your normal stylesheet definition, you can add the following tag ``` <link rel="stylesheet" type="text/css" media="print" href="PrintStyle.css" /> ``` Which will render the document according ...

When I try to print a Unicode string in a Windows console, I get an error . `UnicodeEncodeError: 'charmap' codec can't encode character ....` I assume this is because the Windows console does not accept Unicode-only characters.

It depends on your language and environment. As a rule I wouldn't use it, unless the development environment you're in makes it hard to find the type of the variable. There's also two different types of Hungarian notation. See Joel's article. I can't find it (his names don't exactly make them easy to find), anyone hav...

Actually, the above answer was not completely correct. ``` require 'singleton' class Example include Singleton end ``` You also need to include the require 'singleton' statement.

I think hungarian notation is an interesting footnote along the 'path' to more readable code, and if done properly, is preferable to not-doing it. In saying that though, I'd rather do away with it, and instead of this: ``` int vBox = aBottom * lVerticalSide; ``` write this: ``` int boxVolume = bottomArea * vertica...

In the real world, your chances of taking one design and totally reskinning it without touching the markup are pretty remote. It's fine for blogs and concocted demos like the csszengarden, but it's a bogus benefit on any site with a moderately complex design, really. Using a CMS is far more important. DIVs plus CSS !=...

It is pointless (and distracting) but is in relatively heavy use at my company, at least for types like ints, strings, booleans, and doubles. Things like `sValue`, `iCount`, `dAmount` or `fAmount`, and `bFlag` are everywhere. Once upon a time there was a good reason for this convention. Now, it is a cancer.

Considering that most people that use is following the misunderstood version of it, I'd say it's pretty pointless. If you want to use the original definition of it, it might make more sense, but other than that it is mostly syntactic sugar.
