I'm looking for the best way to take a simple input:
echo -n "Enter a string here: "
read -e STRING
and clean it up by removing non-alphanumeric characters, lower(case), and replacing spaces with underscores.
Does order matter? Is `tr` the best / only way to go about this?

Manipulating cookies on the client side is rather the opposite of "best practice". And it shouldn't be necessary, either. HttpOnly cookies weren't introduced for nothing. |
Since you're using Ubuntu, and not Kubuntu, I assume you're using GNOME. You might be interested in [Nautilus Subversion Integration][1] described on that link.

A great way to manage large sets of configuration is to create custom configuration sections. Phil Haack discusses this very nicely in this article <a href="http://haacked.com/archive/0001/01/01/custom-configuration-sections-in-3-easy-steps.aspx">Custom configuration sections in 3 easy steps</a>

It may be worth taking a look at [C5][1], it's a generic collection library for .NET which includes sets.

I would suggest to load the contents of the selects that don't depend on any other select boxes on page load. Then in the onchange event of those selects load the contents of the rest of the selects that depend on them.

Win32 services are designed to be system-wide, and start running before any user is logged in. If you want something to run on a per-user basis, it's probably better to design it as a regular application and run it from the user's Startup group. |
I think you should ask yourself why you have to go through the hassle of maintaining multiple databases across several platforms and have them in sync with one another. Sounds like there's a lot of redundancy there. Why not just have one instance of that database, since I'm sure it can be made accessible (e.g. via SOA ... |
Actually, having a look at the MinimumSize and MaximumSize (.NET 3.5) in reflector its pretty clear that the designed behaviour is not quite the same as the docs suggest. There is some minimum width constraints determined from a helper class and 0 has no special meaning (i.e. no limit.

NTP is definitely the way to go. Basically fire-and-forget, as long as you let it out the firewall on your local master (which is typically the firewall or router machine.) |
As you've already suggested, NTP is the industry standard solution to this problem, but it either requires Internet connectivity or a stratum 0 source (an accurate hardware clock, like a GPS receiver with a computer interface).

The best answer for you is some sort of DVCS (popular ones being [Git][1], [Mercurial][2], [Darcs][3], [Bazaar][4]...).

Does writing and speaking on software make you a better programmer? |
|blogs|writing|public-speaking|speaking| |
Do you think that writing about software (i.e. having a blog) and speaking on software (and concepts) make you a better programmer?

Yeah, we use a wiki, we also use Google documents. I find that Google documents is better than most wikis I've tried and, if you don't need to track all changes, you lose nothing. Google docs provides a good collaboration framework. |
That's a very open ended question, and depends on many factors.
Generally speaking, if you use a language that has good documentation generation tools (javadoc, doxygen, MS's C# stuff), you should write your documentation above your methods and have your tools generate the pages. The advantage is that you keep the ... |

Absolutely, for one simple reason: It challenges your preconditions. You could write an article about how perfect .NET is for a given situation, only to find someone has used it, and it turned out badly. |
I think the main thing these activities do is force one to more thoroughly research things and research new things. Does this make you a better programmer? I think so. |

I think localhost pretty much resolves to 127.0.0.1 for most platforms but all IPs that start with 127.*.*.* resolve to localhost as well. Try pinging 127.255.255.254 and it'll still respond. |

Is it possible to perhaps have the service create child processes which then adopt the user credentials (or be started with them)? This way you're still limited to a single instance of the service, but it is able to do its per-user jobs all the same. IIRC the Windows Task Scheduler service does this. |
The whole concept of a service is that it is started before any user is even logged on. so even if this was possible, you wouldn't be able to choose between userA and userB when the service starts because none of them is logged on yet. |

Yes. In the work force, being able to communicate effectively is as, and sometimes more important than knowing every obscure detail about language X. |
I believe that is the case. As with teaching, you develop a firmer grasp on the subject when you have to explain to someone else. You get to see what you understand and don't understand in greater detail. |
Absolutely yes. You have the chance to be challenged and questioned and second-guessed in ways you'd never think of on your own. It also gives you a chance to work on the organization and presentation of your ideas. All of this will feed back into the decisions that you make when you're writing code. |

I would argue the opposite: that in general the good programmers love to write and speak about software. It shows that they are passionate about it, and won't accept crap. |
If you write a C++ program, it links dynamically to the C Runtime Library, or CRT for short. This library contains your printf, your malloc, your strtok, etcetera. The library is contained in the file called MSVCR80.DLL. This file is not by default installed on a Windows system, hence the application cannot run.
