If you use the Adobe AIR application Klok for time-tracking, there's a small caveat to watch out for if you wish to synchronize your time data between computers using something like Dropbox or Windows Live Mesh. Basically, if the path of your Klok installation differs from one machine to the other, you don't want to sync all the files in the Klok folder but only the main database file.
Klok stores its data in a file called klok.db, but there are a few other files in there as well, one of which I found to be to cause problems in synchronization between machines. That file is config.xml, which looks like the following:
Note <data-file-location>, the first data node in the file. That file location needs to be the same between your different machines in order to synchronize the full Klok folder. If the installation directories are different, i.e., that line is different between your two Klok installations, you want to just synchronize klok.db.

I wanted to install openSUSE in VirtualBox, and set up a LAMP development environment in it. The "how to" information I found is already available, but it's scattered in different places (blogs, wiki posts, videos, etc.), so I decided to note it down in one place for future reference. I am focusing on the openSUSE part of the installation process and not the VirtualBox part of it, since that's pretty easy to do.
The steps I followed are as follows, along with references to useful instructions:
- Install openSUSE in a new VirtualBox virtual machine.
- Download openSUSE (I used openSUSE 12.1).
- Create a new virtual machine (VM) in VirtualBox, and run the installation from the ISO you just downloaded.
- You shouldn't need to manually install VirtualBox Guest Additions because they get installed with the openSUSE installation.
- Some useful instructions here and here.
- Install Sun Java JDK. This does not come installed or even available in the default repositories.
- I've come across a few programs that either require or work better with Sun Java JDK (like SmartGit and PhpStorm).
- Follow instructions here (the procedure for the x64 version is in the right column). One point to note is that the author recommends not using the RPM version of the installer.
- Set up the LAMP server (instructions here). openSUSE comes with a "pattern" for installing all the required packages in one easy step!
Note: openSUSE by default creates a /public_html directory in your /home directory. Apache/PHP store files in /srv/www/htdocs, but you can also store them in your /home/<username>/public_html directory and access them via http://localhost/~<username>/<filename>.
- Add and auto-mount a shared folder from the Windows 7 host environment.
- Add a shared folder through the VirtualBox VM Settings.
- Follow instructions in the 5th post on this page (that is the procedure that worked for me).

Programmers are a helpful bunch, guiding those less-knowing on the meaning of having balls in the colloquial sense.
As seen on Programmers StackExchange:

Here are some things I've learned about the web design and development world in my short years in it so far:
The web development world is a maze (vs. a labyrinth), littered with innumerable equally-appealing choices. For example:
- PHP frameworks: CodeIgniter, Zend, Symfony, CakePHP, Yii, ...
- Popular web languages: Ruby, Python, PHP, C#, ...
If you're going to get anything done, you have to just step into the maze and start working. The good news is that you can't really go wrong, even if you get lost for a while. There are so many resources out there, and so many useful and cool things have already been done in pretty much any technology you decide to take on.
On the other hand, you can be like the myriad of people asking questions like:
Notice the number of [closed] questions that show up when searching for terms like best, better , and should I learn. There's a good reason for that: questions like that are a waste of time, and are generally asked by people who are afraid and just stalling getting started. I know because I've been there. Pick one and don't look back, unless somehow you've managed to get yourself absolutely stuck at a dead-end.
- It's not enough to read books. (If it were that easy I would be a genius by now.) You have to do the work and practice what you're reading.
- When reading articles out there on the Web (including mine), check the date. Technologies are getting updated so quickly that some fix or trick that applied a few months ago may no longer work. The publication date is the first thing I check before even reading an article. If it's too old I'd rather spend the extra time to find a newer, more relevant piece.
If you're looking to get something done, chances are it's been done before. Spend some time and look around the internet to see if someone's already solved the same or a similar problem. It's worth it. It's even worth it spending some money - you'll be rewarding someone else for their work while saving yourself time and your client money (which in turn could lead to more money in repeat business).
Good places to check are GitHub, CodePlex, StackOverflow, and Bing and Google.
When you eventually need help and post a question online somewhere, do it with others in mind: those who will be taking their own time to help you.
Ask the question first, then give the explanation. If you've got a long-winded explanation behind your question, it's better to put it after the question. That way the reader can scan the question, assess whether they're interested, know enough about the topic to help you, and if so, want to spend the time to read the story behind it.
Be respectful and courteous. Someone else is using their valuable time to read your question and (hopefully) responding to it. More often than not the first answer is less than helpful. That's why there are multiple answers from multiple people with multiple backgrounds and areas of expertise. You won't get very far with the community by being disrespectful to others.
- Your work is automatically sandboxed to the virtual machine you're working in
- You can experiment all you want
- If you use VirtualBox you can take snapshots and easily revert if something breaks
- If you run a Windows host, here is a short script to automatically take a snapshot before a virtual machine launches for use
- Don't mess around with your host environment; only install what's absolutely necessary there
- Make frequent backups.
- Several times a day if you can afford to (in terms of space and computer power)
- Here is what I do for backup
- If and when you do experiment, record your experiments, observations, and results, and share them with others if you like
- It's the best way to learn something for yourself, and it's also nice to share something you've spent hours on that could save another developer hours of time. (Think about all the hours you've saved because of other's blog posts on problems you've struggled with.)
- Get as much RAM as your system can take and/or you can afford
- Source control is a wonderful thing, even if sometimes I wish it were easier to use
- As much as I dislike to say it, the command line is the fastest way
- I dislike to say it because the whole point of GUIs is so you don't have to remember many commands
- Every developer has to strike his own balance between command line and visual interfaces
There will be times when things won't work out with a client. You won't agree with their demands, or they won't agree to your methods. In these cases there is an incident I like to remember from college. On returning a paper he graded back to us, the professor said something to the effect:
Before I return these papers I'd like to point out that this grade is not a judgment of your writing ability or your talent in any way. It's simply an assessment of this particular paper.
The point is, just because things don't work out with one (or two, or three) clients doesn't mean you're not good at what you do. Now if you're not good with three out of three clients, then it's a problem. But if it's three out of fifteen or more clients, just take it as a matter of chance that things didn't work out. Don't chastize yourself or doubt your ability, just move on.
