bdcs··on Waymo Via
>If Waymo is successful, there are potentially massive impacts to the population of the US. Trucking is a major industry.

Certainly, but we don't know if it will be positive or negative. Some studies[0] show increases in human truck driver employment with long-haul being fully automated (plus the work seems nicer).

bdcs··on Vitamin D supplementation to prevent acute respiratory tract infections (2017)
> - Apparently the soil of Scandinavia is well suited to crops that are high in Vitamin D

IIUC it's the other way around. soil/climate allows for foods low in Vitamin D -> Vitamin D needed from other sources -> evolutionary pressure for getting it from the sun -> less melanin in skin

bdcs··on Ask HN: What are your best learning methods/hacks/tips?
Cal Newport's Deep Work(0) is a fantastic treatise on exactly this topic, but extendable to many more.

bdcs··on U.S. Changes Visa Process for High-Skilled Workers
Wages and salaries (and, perhaps, prices) would not go down. Your argument and the parent of it, is falling for the lump of labor fallacy. By adding supply of labor, the demand for labor goes up as well. It is actually well-agreed on by economists, but I see many smart people, on the left and right, get it wrong.

I implore you both to read and listen about it (google/"lump of labor").

bdcs··on A Billionaire Pledges to Fight High Drug Prices, and the Industry Is Rattled
Indeed!

In fact he was outright pro-Universal Healthcare, eg: "Where, as in the case of sickness and accident, neither the desire to avoid such calamities nor the efforts to overcome their consequences are as a rule weakened by the provision of assistance, where, in short, we deal with genuinely insurable risks, the case for the state helping to organise a comprehensive system of social insurance is very strong.

There is no rule. Any attendee is free to barter!

I will say in my experience (and second-hand experience with hundreds if not thousands of participants), that there is literally zero* bartering. And, furthermore, many (cf ~all) people would be aghast at any sort of quid pro quo exchange.

Read the last paragraph from the parent stating they would not return without a large presentation/gift. This captures the spirit/zeitgeist/culture of burning man!

* I have seen some bartering with illicit substances to prove one isn't a law enforcement officer, but the barter amounts to "show me you have some money, even a few cents, and I'll trade you immeasurable money"

bdcs··on Is developer compensation becoming bimodal?
>Sure, if companies were able to immigrate significantly more workers, then salaries at top companies might drop to a degree

Is this not the lump of labor fallacy?

bdcs··on Is developer compensation becoming bimodal?
Fascinating argument, which fits me well (PhD ChemE who learned software and is now SWE at large tech firm).

Allow me to take an alternative argument: Highly-driven students, especially those driven by money, became ChemEs to earn a lot of money and prestige. They looked up highest paying majors and chose ChemE for these reasons. I think it is now obvious SWE is very high paying and prestigious -- perhaps more so than ChemE -- so these highly-driven people switched. It had nothing to do with the topics intrinsically, but rather ChemE was largely perceived as the hardest/most-prestigious field and now SWE is.

bdcs··on Is developer compensation becoming bimodal?
It was nearly correct in my case: While getting a BS in ChemE at CU Boulder, I also earned a got a minor in chemistry and biochemistry (and inorganic chemistry, but I was only allowed two minors for whatever reason).

bdcs··on Google advances AI with ‘one model to learn them all’
One Model To Learn Them All

Deep learning yields great results across many fields, from speech recognition, image classification, to translation. But for each problem, getting a deep model to work well involves research into the architecture and a long period of tuning. We present a single model that yields good results on a number of problems spanning multiple domains. In particular, this single model is trained concurrently on ImageNet, multiple translation tasks, image captioning (COCO dataset), a speech recognition corpus, and an English parsing task. Our model architecture incorporates building blocks from multiple domains. It contains convolutional layers, an attention mechanism, and sparsely-gated layers. Each of these computational blocks is crucial for a subset of the tasks we train on. Interestingly, even if a block is not crucial for a task, we observe that adding it never hurts performance and in most cases improves it on all tasks. We also show that tasks with less data benefit largely from joint training with other tasks, while performance on large tasks degrades only slightly if at all.

bdcs··on Estimating a nuclear blast with bits of paper
Wikipedia says the Trinity test was 20 kilotons. With Fermi estimating 10 kt, he was off by a factor of only two.

Of course Taylor got an estimate within 2 as well, using photographs published in Life magazine.

On a related note: When I was vegan, I said I exclusively ate things made from plants. It was better received and understood. Also I would antagonize friends by giving them vegan pb&js, vegan pickles, vegan French fries, vegan Coke, etc.
bdcs··on Twilio S-1
All nonprofitability means is they expect ROI on dollars spent today. In other words a dollar spent today will, in their model, increase their future (discounted) free cash flow. In even more words, profit is when a company runs out of investible ideas (within the assumptions of their hopefully convincing model). The size of the company has nothing to do with it (canonical example is Amazon where you can change the 28M users to at least 280M and rev in the billions).
bdcs··on Pebble 2, Time 2 + All-New Pebble Core
If you have Google Fi for your main phone (20$/mo + 10$/GB) you can add up to 9 data-only SIMs for 0$/mo + 10$/GB. The per GB is really fair (I think it rounds to the nearest MB and everything left over rolls over to the next month).

bdcs··on Pebble 2, Time 2 + All-New Pebble Core
I'm going to join in since I've been using a pebble for years with great enjoyment.

I treat it as a secretary. I think of different communication media as having different urgencies / time constants. Emails are a daily report. My phone's notifications are an hourly report. Notifications which I forward to my watch are the instant things. Be sure to mercilessly "mute" most apps from bugging you on your wrist. With this setup, I never feel the urge to check my phone. If there is something important, it would've buzzed my wrist.

Here are my subjectively appreciated apps

Homescreen: Fairweather. It is information dense display of weather, sunset time, pressure, vis., etc.

(Top) Button shortcut: Forecast weather. Shows a probability of precipitation over the next 24hrs (I donated for data from forecast.io). Great for avoiding the rain when walking the dog / biking home / etc.

(Bottom) Button shortcut: A bus/train stop info panel. It uses the phone's GPS to tell you when the next buses/trains are coming. Handy for when there is a stop within 100 feet of the bar and you can know if you want that extra beer or not.

Timer/Multitimer are great. Alarms for waking up are great. 7minute workout app is great.

bdcs··on Introducing OpenAI
I agree with you that AI is a well-funded area of research, although if you take the view that traditional forms of research, eg private or academic, come with crippling problems -- short-term horizons, corrupting influence of profits, publish or parish, time wasted in meetings/grant-writing -- then you can see the potential of having a more long-term, focused, and centralized space for inventing AI.
