Last month, the World Wide Web Consortium (W3C) declared HTML5 is officially "feature complete." I decided it was finally time to make the switch from HTML4.01. While reading about all the new tags, I was excited about some tags and confused about the usefulness of others (like repurposing the previously deprecated
<u> for "misspelt words"). I quickly dove in to compatibility charts and performed some of my own testing. One of my greater disappointments was the lack of browser support for the
I set out to find a work around that would enable proper functioning of
summary, that is, to enable it's open/close interactivity. What I found was an effective solution in jquery-details by Mathias Bynens. Unfortunately, this solution depends on another library: jQuery. jQuery is an excellent library which I use in some of my projects, but not all. Since some of my projects do not use jQuery, it seemed unnecessary to include a library as comprehensive as jQuery for the benefit of one simple work-around. So I wrote my own.
To counter the tone of my recent postings about hardship, I would like to rant and ramble lightheartedly to ridiculously about how we express time.
This past weekend the USA ended it's annual observance of Daylight Saving Time, apparently one week after most of the observant northern hemisphere. Many rumors run rampant in our intellectual garden about why we ever started this time of shifting daylight. The one that I hear the most is about farmers, as though they were somehow so disconnected from nature (like us city folk spreading the rumor) that they needed a clock to tell them when there was enough light to work the fields. Wikipedia, on the other hand, credits Daylight Saving Time to George Vernon Hudson, who apparently just wanted more daylight after his shift job to collect insects. The further explanation of its implementation in the United Statesis a bit more practical:more...
I always thought there was something wrong about Pi (3.14159...). It seemed clumsy to use. I was distracted from figuring out why by the apparent simplicity of the constant. The circumference of a circle divided by its diameter just seemed so elegant. How could a constant so elegant be so cumbersome to use? Why would it always drag around its crutch of a 2? Whose brain-child was 'radians', a system for measuring angles that summed to 2π?
These things confused mathmatics for me as a student, and now I know why. Pi is wrong. The better, correct, circle constant is Tau, τ, which is equal to the ever-present 2π. Thanks to Michael Hartl for putting his finger on what is wrong with the way we teach maths with pi, pi. Thanks again, for pointing us to tau, and simpler, more intuitive ways to think about circles, angles, and all the (now) fun things we had to do in school trigonometry and above.more...
How many results are produced by a Google search can be viewed as a rough measure of how popular a thing is -- how much it is talked about online. With that in mind, I searched for a collection of phrases in Google, Yahoo, and Bing. Each phrase was two words; the second always being 'control.' I took the results and charted them for curiosity. Somehow I am not surprised that 'remote control' placed first, but I hoped for 'self control' to place higher. The fact that there is more talk about 'birth control' than about 'self control' ... well, derive your own conclusions.
The values in the chart are expressed in millions of search results and are chosen as the median value for the three searches. Full data in my Google Doc.
To anyone who as been following Lytro, I don't have much to add.
To my friends who haven't had the pleasure of my bending their ear about this, check this out! Lytro has released what they're calling a Light Field Camera. It is a camera unlike anything you've seen. What it does is capture not just an image, but the entire "field" of the image. This means directional information, too. With that extra information, a picture could be re-focused after it is shot. You could change not only the focus, but the effective focal-length. Want more in focus? No problem!
With that ability, the camera doesn't have to worry about focus before you take the picture. This means no shutter delay. When you push the button, you have the picture. This also means wider aperture (f/2), which means great low light performance. The light field data can even be used to generate 3D effects.more...
Paying with a credit card is generally considered to be convenient, safe, and secure. With the ubiquity of merchants accepting credit cards for payment, and the increase in "fraud protection" services from credit card companies, it may seem like there is no reason to carry and pay with cash. Indeed many of my peers think this way, and do not carry cash. It seems we are quickly approaching an era of paperless currency, where all business is conducted electronically. No more cold-hard-cash. No more paper. No more mints. Cool huh?
Not if you run a small business.
It is no secret that the merchants who accept credit cards for payment have to pay transaction fees. After all, the employees at the credit card company have to get paid. It's just not something we often think about.
The cost to merchants varies wildly in a complex swamp of fees, but generally boils down to a monthly fee, a per transaction flat fee, and a per transaction percentage fee. From what I've read and merchants I've talked to, it can be as low as 2% or upwards of 20% of each transaction. The usuric 20% is less common, strongly correlates to small transactions, and comprises mostly of a flat transaction fee. If you've ever wondered why some merchants require a minimum purchase for credit card transactions, this is why.more...
