If you have the ability to install software on your work computer, by far the easiest way to move files back and forth between your home and work computer would be a file synchronizing product like DropBox. But if you don't, what's the best way to move a relatively large file between two remote computers? For small files, email is usually the answer, and for users of Gmail that expands to files of up to 25 MB in size. But with what can often be a big catch: Gmail won't allow you to transfer executable files, even if they are inside a zip archive.

However, if you're simply wanting to move a file between computers, you can exploit the fact that Gmail doesn't actually scan a file to see if it is an executable until you actually try to send the email containing the file. This means that you are free to attach any file up to 25 MB in size to an email in Gmail, as long as you don't send it. You can then log into your Gmail on another computer, and download the attached file, without ever running into the executable file restriction.

Of course, the other easy way around Gmail's limitation is to change the file extension of the file you are sending. If you have an executable file inside a Zip archive, and you change the archive's file extension from .zip to .zzz, for example, Gmail doesn't know what a .zzz file is and does not scan it. Voila, you can now easily send executable files through Gmail.

I hate packing for trips. I will put it off until the last possible moment, and even then some. Part of the reason I hate it is that I'm never quite sure exactly what I need to pack.

If you're in the same boat, you might find the Universal Packing List site as interesting as I do. Basically, the site is a very compact user interface that asks you a set of questions about your upcoming trip, ranging from your gender, to whether you will be washing your own clothes, if you wear glasses, and where in the world you'll be traveling to.

Once you've completed the questionnaire, it spits out a very comprehensive list of things to pack, as well as a to-do list to take care of before you leave. When I say the list is comprehensive, that's a bit of an understatement. For a hypothetical 3 day trip with my kids, here are just the headings it came up with:

I listen to a lot of podcasts, and my queue of things to listen seems to be growing constantly; I can never catch up. What's frustrating about this is that most people talk too slowly on podcasts. To be fair, they are speaking at a reasonable conversational pace, but when you are simply listening to a conversation rather than taking part in it, you can take it all in at a much faster pace.

While iPods have been able to speed up audio books for some time, the latest 3.0 iPhone / iPod Touch release has added the ability to speed up (and slow down) podcasts as well as audiobooks. That's the good news. The bad news is that whatever the algorithm is that is being used to speed up the audio ends up sounding quite rough.

For podcast listeners that are not using an iPhone or iPod Touch, there are not many options for speeding up podcasts, short of doing it yourself manually with a program like Audacity.

Luckily, there's a new site that is looking to take care of this problem for us. PodShifter is a site that will allow you to enter the RSS feed for a given podcast, and it will spit out a new feed URL that will deliver podcasts that are sped up to exactly the speed you prefer. You can choose from slowing down your feed to 0.6 times its original speed, all the way up to 3.0 times the original speed, in increments of 0.2. Based on the demo MP3s on PodShifter's homepage, the sped-up audio is quite smooth.

Unfortunately, in my testing PodShifter has generated new podcast RSS URLs, but when I put them into iTunes, the audio files that I get are exactly the same speed as the originals. I was surprised that they downloaded at all to begin with, so I'm hopeful that there is processing going on in the background and a new version of the podcast will arrive that actually is sped up.

I'd be remiss if I didn't mention that it is quite likely that some podcast publishers will not be thrilled about a republishing service such as this. Larger podcasts that rely on download statistics for determining advertising rates could potentially lose track of the subscribers that sit behind a republishing service like PodShifter. And unfortunately PodShifter's site is not particularly forthcoming with information, so it's hard to determine whether they offer publishers some manner of tracking statistics properly.

In any event, the service that PodShifter provides is a very useful one, and one I hope will succeed. Now excuse me while I go refresh my podcasts to see if any of my PodShifter subscriptions have delivered on its promise.

Creating playlists can be tedious, and every bit of information can help. While some people maintain the ID3 tags in their MP3 files in excruciating detail, others (like me) can't seem to find the time. But when it comes to finding the tempo, no amount of manual ID3 tag maintenance will help.

If you're trying to put together a playlist that contains songs that are a similar speed, knowing the beats-per-minute of each song is immensely helpful. Luckily, there is a free download called BPM Analyzer from MixMeister that will analyze all of your MP3 tracks, and update the ID3 tags in them with exact BPM information. With that done, it's a simple matter of sorting your music library by the beats-per-minute field.

Now you can put together an upbeat energy-boosting playlist full of fast songs, a mellow playlist with slower songs, or pretty much anything you desire. And for the nerds like me, it's just another piece of information to sort and group your music by.

BPM Analyzer is available on both the Windows and Mac operating system.
