calebsurfs··on Introducing Soylent 1.6 Powder
Does soylent include creatine? Its not an essential nutrient but if a human exercises a lot and does not eat meat, creatine levels can get very low. This leads to a lack of energy both mental and physical. Studies have shown [0] improved mental performance in vegans when supplemented with creatine.

Most protein powders have some vitamins sprinkled in. Ive been using Isopure whey protein isolate for a couple years.

calebsurfs··on Mistakes Beginners Make When Working with Databases
As a beginner using MySQL I was expecting not using

  innodb_file_per_table 
or generally learning db configuration to be on the list. It's a huge pain when your little web server runs out of disk space because innodb is eating it all.
calebsurfs··on Ask HN: What are the best JavaScript libraries for data visualization
I really like dygraphs (fast) and dimple (charting layer over d3). Both on github.
calebsurfs··on Can a 700 M.P.H. Train in a Tube Be for Real?
Best part of the article:

"Mr. BamBrogan’s real first name is Kevin. This is just one of many aspects to this undertaking that makes me feel that it will all be revealed as a breathtaking piece of performance art."

Is entrepreneurship sometimes completely, or partially, performance art?

calebsurfs··on I went to the hospital to give birth and tested positive for meth
Oops, thanks.

Cross-reactivity studies don't seem to be published often but searching for albuterol + 'cross reactivity' shows some drug tests are cross reactive with albuterol and some aren't.

This is interesting because I'm a nurse and I deal with people who occasionally test positive for methamphetamine.

We've found that many of these people take Zantac (aka ranitidine, used for acid reflux). This hasn't been studied since 1991[0] but it probably should be again, given increasing rates of meth use.

I wish the author had given the name of her prescription inhaler- Vick's Vapor inhaler has been shown to test positive but albuterol and other steroid inhalers are more common.

calebsurfs··on Nikola Motor Company
I found it odd how difficult it was to figure out what the company's products are: a CNG powered hybrid semi truck and an all terrain vehicle. (Not clear why its a UTV instead of an ATV).

UTV = Utility Task Vehicle

"UTVs differ from all-terrain vehicles (ATVs) in that UTVs typically have a side-by-side seating arrangement, many have seat belts and roll-over protection, and most have a cargo box at the rear of the vehicle. UTVs generally have a higher payload capability and are longer and wider than ATVs"[0]

The video at the bottom of the page goes into great detail on the machine and was not boring at all! :)

calebsurfs··on The Secrets of the Wave Pilots
If you found this interesting and want a fascinating book on the subject I recommend We, the Navigators.

http://www.amazon.com/We-Navigators-Ancient-Landfinding-Paci... It documents a study done of other Pacific Islanders who use waves to navigate. Hawaii was discovered because islanders observed swells from storms in the North Pacific being attenuated as the storm passed 'behind' the island chain.

Islanders also used a completely different form of celestial navigation that involved following series of stars as they rose and set on the horizon. I.e., follow Antares while it is < 10° over the horizon, then follow Pollox, etc until you reach Papeete.
