Mail Trends: what's your email look like on a graph?

Mail Trends
Ever wonder what your email behavior looks like on a graph? Because if you have, we've good news for some of you -- well, those of you that use Gmail. Google coder Mihai Parparita just released a Python program called Mail Trends, which can show you various graphs of data extracted from your email account. You can examine your email behavior from various angles:
  • Distribution of messages by year, month, day, day of week and time of day
  • Distribution of messages by size and your top 40 largest messages
  • The top senders, recipients and mailing lists you're on.
  • Distributions of senders, recipients and mailing lists over time
  • The distribution of thread lengths and the lists and people that result in the longest threads
If you don't use Gmail, fear not. The plan is to eventually release a version that works with other email services, though it is unknown when that version will see the light of day.

Instacalc: Quick, powerful, shareable calculator

Instacalc
Instacalc just blows my mind. It's such a simple idea, brilliantly executed: It's sort of like a Web 2.0 mini-Excel, allowing you to quickly create a calculator for anything--body mass, loan repayment, YouTube valuation--with simple or complex calculations, and then share them with your friends, colleagues, or the world. It knows lots of mathematical operations and functions, understands things like "3 billion" or "8 kbps," and even does some basic programming-like operations.

Unlike a full-fledged spreadsheet, Instacalc just has rows, and in each row you can enter a number or bit of math, and the result will be shown at the end of the row as you type. You can refer to values from other rows by their row number (e.g. 5 + R1), or you can give a row a name by putting "rowname =" before it and then refer to it by name (5 + rowname). You can click on the result at the end of a row to hide the row and show only the result, and you can put "//" before a row to make it into a comment, i.e. a text label that doesn't do anything but give information to whoever's using your Instacalc. If you've ever done any programming, all of this is probably sounding pretty familiar, but even if you haven't Instacalc is easy to use. On top of all the various operations, you can also quickly create bar, pie, and line charts, like this country population chart.

But wait, it gets better. Like any good Web 2.0 service, Instacalc lets you embed your calculator in any web page with a snippet of HTML.

Obviously, I'm very impressed by Instacalc and am shuffling it straight into my bookmarks. Head over there and check out some of the sample calculators to quickly get an idea of what it's capable of. Once you've played around a bit, post links to your Instacalcs in the comments.

Graphically view your disk space usage with Filelight

Filelight

Filelight is a Linux utility that creates a concentric graph of your computer's disk usage. Each color represents a different type of file, such as documents or apps, so it's easy to tell which is the biggest bully on the block. I found a utility like this for Mac OS X over on TUAW by the name of Disk Inventory X - has anyone seen a similar app for Windows?

No specific OS flavor is required, though Qt 3.2 and KDE 3.2 are. Filelight is available from MethyBlue and is released under the GNU General Public License.

A First Look at the New Yahoo! Finance Charts Beta

Yahoo! Finance Charts Beta

Earlier this week Yahoo! announced changes that would roll out soon to upgrade aspects of the Yahoo! Finance property. One of these changes, and probably the most significant for daily users, is the completely overhauled Stock Charts.

When Google rolled out Google Finance property, most of the hubbub around their offering was the dynamic charts. These hadn't been seen before anywhere and had a lot of "kewl" factor in them. Even without the kewl charts, Yahoo! continued to be the most comprehensive and most visited financial resource on the web. And now, Y! is rolling out their version of dynamic stock charts with lots of "kewl" factor. Read on for an overview of the new features and my thoughts.
