Zinc: the only supplement that helps colds

So it turns out my personal experience with zinc has some scientific backing now!

Several years ago I realized that I had a zinc deficiency -- a very common mineral deficiency these days due to our ever worsening diets.

In addition to eating foods high in zinc, like pumpkin seeds, legumes and meat, I also started taking supplements when I felt a cold coming on.

I personally found that if I took too much at once (15mg+), especially without food, I would get severe nausea for a few minutes.

Instead, I eat a few of the 5mg zinc lozenges, spaced throughout the day. They're chewable, taste good, and may actually help with absorption by spreading it out over time.

A recent study has shown that of all "common" supplements (vitamin C, echinacea, ginseng, etc.) only zinc had a substantial effect:
At least two trials indicated that children who took 10 or 15mg of zinc sulphate daily had lower rates of colds and fewer absences from school due to colds. Read more: Zinc not Vitamin C…

E-commerce 101: Allow your customers to pay you

Here's a quick e-commerce lesson for you: Don't validate credit card transactions based on IP address location.

I left the internet fax provider I've had since 2003 because they wouldn't let me pay them.

I wasted an embarrassingly long time trying to find a cheap/free way mask my IP address. I eventually gave up trying to give them money.

I Googled, read a few quick reviews, and found a new, better provider in 5 minutes.

Lots of customers travel or live outside of their home country.

Don't make it difficult (or impossible) for them to pay you.

Evernote is not so great

I've only tried Evernote a few times in passing, but it always came across as a bit of a bloated and unreliable POS.

Seems like perhaps I wasn't too far off... See: Evernote, the bug-ridden elephant

More discussion on Hacker News here. Most people seem to agree.

Sort of like some operating systems, they've been locked into a piece of software that keeps getting larger and less reliable over time.
