alvern··on The impact of the ‘open’ workspace on human collaboration
Can you elaborate on this? I don't get the connection between open offices and Myers Briggs.
alvern··on Bike Share Oversupply in China
You can buy shipping containers of these from Japan and China.

If you want 10 inside the US, just pick them up off the playa after Burning Man ;D

alvern··on Why Can’t Riding Bikes in America Just Be Normal?
+1 for the Yuba Supermarche. That cargo bike is super fun to ride. The steering takes a minute to get used to, it has a 4:3 ratio. For every degree you turn the handlebars, the front wheel turns 1.33 times more. It handles speeds up to 30mph suprisingly well.

I made a quick video when we got one in the shop last summer.

alvern··on Car Hacker's Handbook (2016)
I have gotten read only CAN data from a 2006 Toyota Prius.

I used TUCRRC CAN ID's to map the output. [1] The interface board was an early Macchina, Arduino 256 with CAN hat and 12V power on board. [2]

alvern··on Kodak shares up as it announces KODAKCoin cryptocurrency
I don't get the value in the ICO.

Photographer licenses image on KodakONE, receives KodakCOIN as payment. KodakONE uses blockchain to sell and protect the image from theft down the line. KodakONE uses lawyers to DMCA those who don't attribute or pay for the image.

alvern··on Nvidia Announces “Titan V” Video Card: GV100 for $3000
What are the use cases for the Titan V vs. Radeon Pro SSG?

Just ML? Higher memory bandwidth?

alvern··on Bitcoin exploding, exchangesites starting to fail
cryptowat.ch is still reporting price updates from GDAX

EDIT, as of 11:48 CST, GDAX is showing 16849 USD per BTC, while the other USD exchanges have gone down to ~15200

alvern··on Why does man print “gimme gimme gimme” at 00:30?
0_0

I remember the days of batch creating UPC barcodes on an AS400

alvern··on How the Kodi Box Took Over Piracy
Oh man, I used a friends X1 box this weekend. The voice search was terrible. It couldn't understand "Chucky" in a midwestern accent.
alvern··on First possible interstellar object detected in our solar system
91800 kmh per hour incoming, 158400 kmh outgoing. This space puppy just gained 66600 kmh from passing through our solar gravity well. Not particularly relevant, but very interesting!
alvern··on Intel Shipping Nervana Neural Network Processor First Silicon Before Year End
I'm betting it shares a lot with the Movidius Neural Compute Stick and uses Caffe for the ML.

alvern··on I printed a huge batch of connectors to make a 15ft structure out of plastic
Very cool approach to scaling a project out of small components.

I wonder if the print time is 144 parts in 36 hours or 36 hours per print. Thats 15 minutes a print if it is the former!

alvern··on 3D metal printing is about to go mainstream
This may bring the per part costs closer to what prototyping costs come in at for CNC machining or Metal Injection Molding.

I don't see this being used with a lot of exotic materials yet, but for stainless steel this is great.

alvern··on The 20 Best Cars That Still Offer a Manual Transmission in the US
Oh the headaches those hill assist solenoids cause on Subaru's. Especially when they start to wear out or get electrical issues.
alvern··on Cycling to work can cut cancer and heart disease, says study
I've been commuting electric 11 miles each way for over a year. In my time I've found limiting myself to 18-20mph pedal assisted is the best use of my battery and my body. I still get some workout but not enough to sweat through my clothes. The bike averages 400w consumption and I've gotten used to running bigger batteries than my commute needs. Currently I'm running Multistar Lipo's at 12s2p for 50v charged and 20ah max range. I consume 6-8ah daily.
alvern··on Atmospheric CO2 levels accelerate upwards
[E]very man ought to say to himself, "Am I really the kind of man who has the right to act in such a way that humanity might guide itself by my actions?”

alvern··on Thousands of underground gas bubbles poised to 'explode' in Arctic
Here is a list of articles so far about methane capture and biogas. This is lab based experiments in small quantities (~50ml) but it could be scaled up. So in a foggy smog future where we all live in domes, these methane processors could slowly grab the energy back from the atmosphere.

alvern··on Why I Dissented
That RS article is kinda gossipy garbage, the WaPo article that was written about him in 2009 does a better job illuminating Kashkari.

alvern··on America’s Fastest-Growing Loan Category Has Eerie Echoes of Subprime Crisis
As someone who just signed up for grid tied residential solar panels, this made me review my loan documents again.

Nothing in my documents mention PACE, or the debt-to-tax levy that ruined the old ladies' financials in the article.

alvern··on Ask HN: Does anyone here have an art degree?
I ended up taking a BFA in Fine Art after realizing I would need another semester for a Graphic Design/Digital Media degree. My degree is from a state university.

Worked as a freelancer web dev for a while, did IT helpdesk, went back to tech school, got involved in hackerspaces, got a job in machining which was more stable than web dev work & less mindnumbing customer facing than helpdesk. Paid my dues and worked my way from running machines to building machines, programming PLC's, and writing programs. Now I'm part of the Advanced Development engineering team. I spend a lot of time pulling data to run reports, 3d modeling parts & assemblies, & hands on troubleshooting of our prototypes.

Web development helped with the industrial programming I deal with & the art degree taught me visualization, deconstruction, and problem solving.

Anecdotally, I used to scour McMaster Carr for parts to make for sculptures. Now I actually order stuff for it's intended uses.

alvern··on Metro areas suffering from brain drain or benefiting from brain concentration
What is the brain density in northern Alabama? Huntsville? Is that NASA/aerospace jobs still?
alvern··on How “Black Mirror” Gets Its Barely Sci-Fi Tech Just Right
The Twitter-death-drone episode could have been a stand alone movie. Everything in that story and execution was polished and well put together. The pacing was fantastic compared to the others in the bunch.
alvern··on Don’t go to art school (2013)
We as a society need a different post-secondary experience.

I went to art school at a state university. Ended up with a BFA in studio art. When I get my background check pulled it just says BFA from STATE UNIVERSITY 2011. It doesn't say it was in art. After that I went to a tech school for a semester and started working in manufacturing. Having my BFA was critical in jumping through the HR loop to get to my current position of analyst.

My department hires with a bias towards fresh graduates with engineering degrees. These workers are great for 6-18 months but they always leave for greener pastures. I keep getting raises to stay were I am. Out of the degrees that the long term coworkers hold, most are in physics, mathematics, or criminology.

alvern··on Uber Self-Driving Truck Packed with Budweiser Makes First Delivery in Colorado
That's a very pertinent question. I guess it falls on if you own a personal vehicle that you maintain until they become of age. Easy financing for personal autos may soon dissipate when the self driving car comes of age.

Learning to drive may become a bespoke thing in 30 years. You only learn because your father/mother/family is an enthusiast that kept a sports car or classic maintained.

The commercial pick up truck could hold out as the last non-autonomous vehicle. Maintenance and service will still be done by humans, for now.

alvern··on Uber Self-Driving Truck Packed with Budweiser Makes First Delivery in Colorado
Truckers operate on the 14/11 rule currently. 14 hours from when you wake up, 11 hours from the start of driving. If they can throw that out a tractor trailer can log twice the hours in a 24 hour day than current regulations allow.
alvern··on Uber Self-Driving Truck Packed with Budweiser Makes First Delivery in Colorado
The article cited 1.5 million jobs in the US trucking industry. That number seems low.

edit; That number seems hard to define. Of the 7.1 million people employed throughout the economy in jobs related to trucking activity, 3.4 million were truck drivers in 2014. There are over 10 million CDL (Commercial Driver’s License) holders in the U.S., but most are not current drivers and not all are truck drivers. There are between 2.5 million and 3 million trucks on the road today that require a driver to have some sort of CDL. Of those trucks, 1. 6 million are tractor - trailers. Of those tractor - trailers, n o more than 800,000 are used in OTR (i.e., non - local) operations.

alvern··on The Most and Least Expensive Cars to Maintain
Close, the prius drivetrain is two brushless 3 phase motors nested in one another. This allows regenerative braking and charging while still providing power to the final drive. Fun fact the ICE in the prius is an (1) Atkinson cycle which operates at a specific efficiency instead of a powerband. The engine revs up to a low or high range but doesn't have a traditional linear powerband.

alvern··on 8x Nvidia GTX 1080 Hashcat Benchmarks
Thanks for posting this, I was looking at this type of build with CUDA before pascal was announced.
alvern··on Electric Bikes Won Over China. Is the U.S. Next?
I ride 20 miles a day in Minneapolis on my e-bike.

My biggest fear is when we will ruin it for everyone. There just isn't the proper infrastructure for them. Bike paths around here have 10mph speed limit signs and are mostly mixed use. Not enough connecting roads have bike lanes.

It will grow wildly popular once a cheap US based lithium battery supplier appears (Tesla/Panasonic).

alvern··on Ask HN: Need to generate 3D models of simple shapes for training
[1] Openscad would be the first thing that comes to mind for this. Some random parameters or an evolutionary algorithm could produce some viable results.
