wmblaettler··on Uber enters dockless bike wars with Jump acquisition
Dockless gives gives you closer to end-to-end or "last mile" so much more than docked systems. With docked systems, you have to walk to both the pickup dock and find a drop off dock near your actual destination for a one way ride. So your "last mile" is very nearly always walking. They are limited to n(n-1)/2 routes where n is a docking station. With dockless, it's more like a car but without the hassle of finding a parking space, you can ride right up to your destination wherever that may be, and just get off the bike leaving it there. The only walking is to the nearest available bike at the outset of the trip. Data point of one here, I've visited cities with docked systems and commented on how cool it would be to use it, but I visited Seattle and actually used one of their dockless systems for several days during my stay, from short multi-block rides to a 14 mile round trip ride. It's tremendously useful for the shorter trips that are just too far for walking. The longer trip was for the heck of if it to see a little more of the city by bike with an errand to pick up a laptop charger needed that morning for my wife.
wmblaettler··on Boosting teeth’s healing ability by mobilizing stem cells in dental pulp
My dentist, a younger generation who took over the practice from a retiring dentist, has installed a Cerec crown milling machine. It was amazing to see the tooth modelled in 3d using a series of photos, then I watched my dentist raise the ridges of the tooth to create what would become the crown. After a few clicks he sent it off to be made - in the next room! In literally 10 minutes he had a crown milled from a block of dental porcelain or some kind of hard ceramic, ready to be fitted in my mouth. See a video of the process here: https://www.youtube.com/watch?v=ajj4zkXHe6U

wmblaettler··on Taking the SCiO Food Analyzer Grocery Shopping
While initially skeptical myself, I found a bit of information on Consumer Physics' site stating that they use near-infrared spectroscopy. Doing a little initial research, it seems plausible that they could glean a number of useful traits from agricultural products, including soluble solids (i.e. sugar content in fruits), acidity, moisture content and more.

wmblaettler··on Planet Launches Satellite Constellation to Image the Whole Planet Daily
For anyone like me that was initially picturing 88 "large" satellites requiring multiple launch vehicles - this was 88 micro satellites: 10cm x 10cm x 30cm from a single launch vehicle.

On one hand it's fascinating to see the miniaturization of satellite technology, while on the other, one has to think about the amount of "junk" floating around our planet, some of it not much larger than a soda can.

wmblaettler··on Ask HN: What is the biggest untapped opportunity for startups?
"Calories Not Absorbed" really got me thinking. While a food is labeled with their potential calories - the amount actually extracted from the food by your gut will vary significantly based on the composition of the food. The bioavailability of calories for example in a cookie versus some fibrous raw vegetable are going to differ significantly, being absorbed at different rates and to differing degrees of completeness.

Here is an interesting article with an important take away: "In general, it seems that the more processed foods are the more they actually give us the number of calories we see on the box" https://blogs.scientificamerican.com/guest-blog/the-hidden-t...

I can confirm. I had the same experience minus the trainee. Had my wisdom teeth extracted while in the Marines. It was over in less than 30 seconds - no time for anesthesia to kick in nor do I remember him administering any. Crack, crack, yank - done.
wmblaettler··on Show HN: Bitesnap – Deep Learning Meets Food Logging
I just logged a couple of meals with it - really like the slick interface - it's very intuitive. One of the main things preventing me from using other services is how clunky / frustrating they are. This is a good balance between "close enough" and too much tedium. Nice work!

One other area of feedback - while the onboarding was slick, I felt the hours of activity to the labeled "level" seemed a bit off. For example I do a high-intensity workout almost every day of the week for over an hour either: strength training or cardio and the level of activity for 7 hours per week only put me at "lightly active" (I forget the actual terminology and cannot restart the onboarding screens without uninstalling). I was just curious how you came up with the activity scale.

Love this for prepared meals and home cooked meals, where you need to analyze the ingredients of a dish. Have you considered adding the ability to recognize a standard FDA Nutrition facts label as well? For example if I have a protein bar, it would be great to snap a picture of the label and OCR the macros. I know that differs though from your current tech of a CNN for image analysis, but it would round out the product to cover a greater percent of foods eaten.

wmblaettler··on Lucee – A lightweight dynamic scripting language for the JVM
Lucee is a fork of Railo, which was an open source alternative to ColdFusion (owned by Adobe, formerly Macromedia, formerly Allaire) which was written by JJ Allaire 20 years ago. I am sure most ColdFusion/CFML language docs would be pertinent to Lucee. ColdFusion was a rather prominent server side language in the late 90's and early 2000's. There are a bunch of companies that still use it today - I work for one. Overall though I would say it's widespread usage is on a significant decline. It can be very fast to get something up and running quickly but similar to PHP, can become a mess if one is not careful as you can freely mix data access, business logic and templating together.
wmblaettler··on So You Wanna Buy a Telescope: Advice for Beginners (2015)
Bought the recommended Orion XT8 Dobsonian a year ago for my 10 year old daughter (ok, and for myself!). It is super easy to setup (minutes), captures plenty of light and has been a joy to view through. I have observed the moon, Saturn, Jupiter and its moons and several Messier objects - even tracked a few satellites as they transited overhead.
