jonbarker··on Probiotics are mostly useless and can actually hurt you
This research needs to be conducted in conjunction with the effects of prebiotics (ie certain fibrous foods). From what I understand, populating your gut with bacteria but failing to provide those bacteria with the right food is likely to fail.
jonbarker··on How to Hire
I feel like there is a presidential golf joke in there somewhere.
jonbarker··on Grue and Bleen: New riddle of induction
I think you are expecting the term 'validity' to mean more than what it technically means to people in philosophy, which is that it 'adheres to the form of either Modus Ponens or Modus Tollens'. Colloquially it has come to mean more like what soundness means, which is valid but also with true premises.
jonbarker··on Grue and Bleen: New riddle of induction
Not sure, but I can use deduction: 1) If induction is valid, then it follows that we can use induction to reason about the world. 2) But we can't use it to reason about the world, 3) so it isn't valid. (Modus Tollens) This is valid, but not necessarily sound. Soundness implies that first two statements (premises) are also true. The second premise is clearly not true, because we use induction to reason all the time. So the conclusion #3, while it follows as a valid argument, cannot be said to be a 'sound conclusion.'
jonbarker··on Ending support for Dropbox syncing to drives with certain uncommon file systems
Use a flow to replicate your onedrive in Azure Files, then mount it to your Linux box: https://flow.microsoft.com/en-us/galleries/public/templates/... AND https://docs.microsoft.com/en-us/azure/storage/files/storage...
jonbarker··on Tech’s Military Dilemma
I don't think the winner matters; if the US had lost, economic growth would have resulted anyway, just elsewhere.
jonbarker··on Tech’s Military Dilemma
A lot of economic growth also came out of World War II, but this isn't something we want to repeat.
jonbarker··on Seaweed could be scrubbing more carbon from the atmosphere than expected (2017)
There is a term for this 'solution based optimism, often of a technocratic nature': Solutionism.

Agreed, homeostasis is something we observe in evolved organisms, not in planets whose inhabitant organisms became self aware and industrialized suddenly.
jonbarker··on 4D toys
This is why as an armchair physicist I'm excited about the new neutrino observations and research going on, mainly because neutrinos aren't affected by gravitational lensing and other effects other particles encounter as they 'roll around' on space-time. Would it be possible to understand conceptually how other dimensions extend out of space time? I'm imagining a Y-axis perpendicular to the space-time fabric....
jonbarker··on 4D toys
Stereo parallax, great term. In other words how cross-eyed we are.
jonbarker··on How LeBron James' new public school is the first of its kind
Test culture promotes lack of growth mindset as students tend to associate their capabilities with their scores from an early age. The earlier we start stratifying students by test scores the more we are likely to develop adults who believe in fixed ability and who don't want to challenge themselves. This is exacerbated when you start separating students into physically different schools based on test scores.
jonbarker··on The open-plan office is a terrible, horrible, no good, very bad idea
Knowledge workers, aka the creative class, are required to be on both schedules. They are both makers and managers. So if they are doing it 'right' they basically have two jobs.
jonbarker··on Ask HN: As a team lead how to handle project going off the rails?
A good customer success team can patch sales up that might have promised features that won't be to spec. But that bandaid only lasts for a short time.
jonbarker··on Why Isn't Debugging Treated as a First-Class Activity?
My only complaint about my meatware computer is that it has a really bad ability to handle space complexity. With paper I can do OK with time complexity (although clockspeed is also an issue).
jonbarker··on Thailand cave rescue: all 12 boys and coach successfully rescued
With all due respect lets all be wary of the 'cult of sacrifice' which often takes hold when someone dies to save someone else. Any time someone dies to save someone else, I suggest the appropriate reaction is that we should simply regret among ourselves that we didn't develop a technological solution to the problem before the problem presented itself, not engage in hero worship (please don't read this as diminishing what this person did, it was a sacrifice, and those kids owe it to him to live good lives now).
jonbarker··on Find and list all your Twitter mutuals
Ah, I read this wrong. I thought it was look someone up and figure out who you follow whom they also follow. Would rather you call this 'reciprocals'.
jonbarker··on Is Vertical Farming Really the Future of Agriculture?
Policy idea that will never get passed: provide a tax credit for those who eat more efficiently using some ratio of CO2 emissions over calories consumed. Add some measure for food waste in there too.
jonbarker··on Advice
To that I'd add if you buy make sure you are pretty sure you will be in the local market for work for 6-7 years, so even if the mortgage is below 30% and rent is more like 50% if you aren't confident you'll stay put for a while you still shouldn't buy. I think there is an irrational scramble to buy going on now too although I think it is not at the scale that caused the global financial crisis.
jonbarker··on Advice
Having lived there and now living in a cheaper real estate market I am grateful for having lived there, where I could not afford a house. I am now no longer interested in owning residential real estate no matter where I go!
jonbarker··on The impact of the ‘open’ workspace on human collaboration
Having worked in wework, open floorplans with 'pods', and the cube farm setup, I prefer the farm. The problem is that most cubes don't actually cancel out noise too well so you are constantly overhearing things causing distraction. There really is no substitute for uninterrupted silence which is probably not achievable in any office where the company is not willing to invest in individual rooms for each person.
jonbarker··on Ask HN: Pros and cons of working at a startup in 2018?
I would say the 'market rate' for the big tech cos cannot be applied to the financial analysis of hiring in startups because most startups have cash burn, and big tech is profitable. If you somehow negotiate a startup to pay you a google like salary you probably won't have much fun because you will be viewed as an even riskier hire than you were to begin with. There will be even more pressure to perform than there already was.
jonbarker··on Airbnb is 'sunsetting' React Native, reinvesting all efforts back into native
I believe you are correct, so they could sunset the version of their app built with React Native, but only fb could 'sunset react native'.
jonbarker··on The CEO of Stripe reveals what it's really like running a $9.2B startup
There are three subcategories of innovation: product, process, and financial innovation. So you could be a water startup if your water is not differentiated but you have either some new way of financing the production of water or some new process for producing said water.
jonbarker··on Solar Surpasses Gas and Wind as Biggest Source of New U.S. Power
Zero emission cars are great; how about an apartment building with an attached parking structure with free power coming straight from the roof?
jonbarker··on Ask HN: Is 'search' a solved problem?
Google returns results specifically showing which terms were missing if this were the case for me. This is useful for finding articles with intersections of concepts (assuming I got the terminology/jargon right) and knowing when those probably don't exist, so I like the feature.
jonbarker··on Ask HN: Is there a new habit you cultivated recently that is really paying off?
I have recently removed the habit of 'relentless skill acquisition' in favor of meditation. If I had a spare 20 minutes I used to practice various skills that I wanted to become good at. While this is probably better than mindlessly ingesting social media or the internet, it has the unique problem of allowing one's identity to get caught up in how good at skill acquisition one can get, and also requires concentration, which is not quite as beneficial to the mind as meditation. The side benefit to this is that it amazingly reduces spending in support of hobbies, which was an ancillary budgetary concern. In short, if you stop visualizing yourself as 'good at something' and then needing to purchase the gear in support of that hobby, you save a lot of cash.
jonbarker··on Solar Surpasses Gas and Wind as Biggest Source of New U.S. Power
We need multifamily dwellings with the feature of no utilities bill because of local renewable energy on site. This would be awesome. The current vision of the future being sold to us seems to be single family homes with electric cars in the garage and solar cells on the roof. A horrible use of land and not really scalable to global population levels given the rise of cities.
jonbarker··on The Repeal of Net Neutrality Is Official
I don't think the debate is over whether to allow Netflix to survive, Netflix will be OK and has a good bargaining position with regard to ISPs because they have content everyone wants. The more interesting question is are we creating a system that allows independent bloggers, vloggers, and other content creators to get discovered and be compensated either through ads or subscriptions or some other model.

They are already tiering their service based on customer bandwidth requirements (gamer internet, casual occasional streaming, or super slow).
