Gmail unsubscribes from spam for you

The guys from big G never cease to amaze me. I was deleting an old coupon message from Pro Flowers today and accidentally hit the “Report Spam” button instead of “Delete”, and was greeting with this: I thought unsubscribing from legitimate mailing lists was already pretty easy, but Google decided that one step was still one too many. The usability focus these guy extrude is mind-blowing at times. If you’re curious, that “Learn more” link heads to a Gmail Help article.

Get Inspired: JK Wedding Entrance

Just the latest entry in my get inspired series, my wife let me in on this one. It’s apparently made the news and ended up in more than a few facebook posts, so I am (as usual) just late to party. Oh well. Always dance, and always do it to your own beat. Have a great weekend!

A bit of bad Google math

The following screenshot was taken from the documentation for Google Page Speed (aka the Google version of YSlow), under the section “Parallelize downloads across hostnames”… I don’t know about you, but I love looking at half-delivered web pages. Let’s hope the guy who wrote this isn’t also responsible for the search engine’s built-in calculator.

Do I need to backup my Amazon S3 bucket?

If I store critical data in an Amazon S3 bucket, do I need to keep a backup copy somewhere else, or duplicate everything to a second bucket? I searched high and low for an answer to the question, and couldn’t find a definitive word. I guess I should have read Amazon’s own design requirements first… Amazon S3 was built to fulfill the following design requirements: [ … ] Reliable: Store data durably, with 99.

Build a slick Twitter feed on your site

A few months ago I published an article describing how to output a Twitter stream on a page using PHP, and later followed up with two more to polish the display. The article content and code examples have since been tweaked based on feedback and my own debugging. If you haven’t already had a look, or missed a portion, here’s the full series: * Display Twitter updates on your website * Calculate dates and times in different timezones (translate Twitter timestamps) * Parse URL’s in text, create links (automatically link URL's in stream) * Download and store your Twitter posts in a database If you have any comments or questions, be sure to post them under the proper article.

Firing a customer is okay, but not in this case

An effective business always remembers that their relationship with a client is a two-way street. If the client isn’t holding up their end of the bargain, the company can and should drop them. This is called firing your customers. The discussion surrounding this notion, both pro and con, is pretty vast, and I recommend you do your own research to ensure you take the right approach for your market, your business, and yourself.

How to be a great salesman

Dave Ramsey is a fantastic businessman with an approach to businesses and finances that eschews what works over what’s hot. Given Wall Street’s track record of late, I’d say that’s a really good thing. He’s got a good regular column called Dave Says, answering questions about personal finance and business (with a focus on entrepreneurs and SOHO’s). The following came from the latest post, and I thought it stood out as a gem for anyone who’s their own sales force:

Change a select menu using jQuery

I don’t know why this is mind bending, but I seem to hit a wall every time I want to do page manipulations involving ` boxes. Particularly, when I want to **change** the value selected. Based on the number of support posts I found, I'm clearly not alone. There are two common ways to change the value selected (i.e. displayed) in a menu: alter theselectedIndexor thevalueattribute. Which one you use depends on the information you have at hand to alter the

Entrepreneurs - think like this guy

In a great article discussing how to demo a product to investors, Jason Calacanis says the following under the heading “The best products take less than five minutes to demo”… Steve Jobs does take the demo details to a fairly detailed level, but you and I are not Steve Jobs. There is only one Steve Jobs and there is only one Apple. You’re never going to build something as cool as Steve, and as such there is no need for you to talk about your product for five or ten minutes.
