throwawayaway12··on Uber will start deactivating riders with low ratings
300 deaths seems like a very insignificant figure to be worked up over.
throwawayaway12··on Ask HN: Auditing a Class as a Non-Student?
My experience has been as an enrolled PhD student in the US, so my thoughts may not completely apply.

I would just go talk to the professor teaching the class if you do not care about any documents saying you took the class. I have sat in on many different classes this way.

Things to note: -You may have some trouble on both extremes of class enrollment. Some courses require a minimum number of students to be enrolled for the class for it to be offered, so if there are not enough or bare minimum number of people taking the class you might experience some resistance. On the opposite end, for classes with long waitlists, you may not be able to sit in. -If you are not affiliated with the university, you may have trouble accessing course files that are locked behind a university authentication.

My advice if you want to go this route is to minimize your impact on the professor. Wanting special accommodations, such as special delivery of class materials or participating in homeworks/projects/exams may give some professors pause.

throwawayaway12··on Why is nuclear fusion so hard?
Warm Dense Matter can be thought of as ionized jello.
throwawayaway12··on De-facto closed source: the case for understandable software
I think you have pretty much proved his point.

>I realise it's hard for FOSS advocates to understand this, because it's a fundamental flaw with the FOSS philosophy. The benefits are "obvious" to crusaders, but the objective reality is that large swathes of FOSS are full of casual or hobby code that barely works, has gaping security vulns, and/or is nowhere close to being robust enough for production.

>And the solution then is to not use FOSS, because then you don't have to take the internals on trust?

I think the point is to realize FOSS is not a utopia and has tradeoffs like everything else.

throwawayaway12··on Companies struggling to fill jobs 'should try paying more,' Fed's Kashkari says
Do you want him to save and pay for college himself? If so, a livable wage doesn't seem too crazy with (US) college tuition.
throwawayaway12··on Chinese Tokamak reaches over 100M degrees
>The immense engineering challenge here is to heat plasma to ridiculous temperatures, and keep it confined in a very small volume at great temperature and pressure to mimic conditions that give rise to nuclear fusion in the center of stars.

This is not exactly true. Inertial confinement fusion has conditions that are similar to stars. The engineering challenge for magnetically confined fusion to keep the low density plasma confined for long time durations for fusion.

For anyone interested in further reading, look up the Lawson Criterion.

throwawayaway12··on Name and Shame: IBM
I think it is more that candidates (especially well qualified ones) view the interview process as a two way street. The company is probing you for competence/fit for the position and the candidate is probing the company for things like culture fit.
throwawayaway12··on Ask HN: Best way to publish papers as a non-scholar?
I think that this covers the general situation pretty well.

I would also consider who you want your audience to be and the scope. If it is something that you want a non-expert to read, consider a blog post. On the other hand you may want to consider something like a patent if it is something you want to monetize. Lastly, consider peer reviewed journals if it is intended to be consumed by domain experts. All of this is from physics research perspective and may be different depending on your area.

throwawayaway12··on Building a Kickass Portfolio
I am curious if anyone has advice/tips for getting a simple portfolio up and running. I am a physics phd student who has worked on a few side projects that I would like to showcase. I am looking into Jekyll and hosting it on github, but I am not sure if this is ideal for a simple static site.
throwawayaway12··on That $35 that scientific journals charge goes 100% to publisher, 0% to authors
Exactly this. Also different journals act as a weak filter for impact of the research.
throwawayaway12··on Teach Yourself Computer Science
I don't think it is that unusual for grad students to research a try during PhD, decide it is not for them, and then move onto other things afterwards. This is from a physics grad school perspective though.
throwawayaway12··on Launch HN: The Lobby (YC W18) – 1-on-1 calls with company insiders to get hired
This seems pretty interesting and useful!

It does seem like the pricing structure does not incentivize people actually getting jobs though. With a small pool of people (people looking for top finance jobs) it seems like the way to make the most money is to perpetually sell job seekers mock interviews, rather than prioritizing a job seeker to find a position on the first go. Is this a fair reading of the situation?

throwawayaway12··on Your success isn’t down to free will – luck determines everything
I recall that the first episode of very bad wizards addressed this aspect of free will well.[0]

throwawayaway12··on Show HN: A HN/Reddit-style site for scientific pre-prints and publications
It would be helpful to link the study. Without seeing the paper, I would be cautious of separating the paper and conclusions it draws from a possible news article that has extrapolated or expanded the conclusion actually made in the paper.
throwawayaway12··on Show HN: A HN/Reddit-style site for scientific pre-prints and publications
I somewhat disagree.

Academic journal papers are meant to be digested by experts in that topic, not the general population. It seems necessary to have a filter on registration to ensure that the platform is useful to these experts. You could imagine the restriction could be relaxed to research institution emails -or- a referral.

Even with a restrictive registration, the platform could still be useful to the a non-expert who is interested in the topic by reading the exchanges between experts.

throwawayaway12··on Yuzu – Nintendo Switch Emulator
While this is true, I would imagine that sales figures affect the future of devs at the game studios (layoffs, new projects, etc).
throwawayaway12··on Ask HN: Delay buying new devices due to Meltdown/Spectre CPU bug?
They might have the same macbook pro, but it might not be a dedicated email/youtube machine.
throwawayaway12··on A feature that arXiv should have built years ago
I think this is certainly true. Research papers are typically written so that a person with training in the field can understand and replicate the work. Note that the general population is not the intended audience. Mediums like news articles and blog posts are a more effective way of explaining the background and significance of a certain piece of research to the masses.
throwawayaway12··on Road map to clean energy using laser beam ignition of boron-hydrogen fusion
There are definitely petawatt class lasers currently (ex. the Texas petawatt). I think most are of order 100 fs.
throwawayaway12··on Road map to clean energy using laser beam ignition of boron-hydrogen fusion
https://lasers.llnl.gov/science/stockpile-stewardship

"Because it is the only facility that can create the conditions that are relevant to understanding the operation of modern nuclear weapons, NIF is a crucial element of stockpile stewardship. NIF creates conditions—temperatures of 100 million degrees and pressures 100 billion times that of the Earth’s atmosphere—similar to those in stars and detonating nuclear weapons."

throwawayaway12··on Road map to clean energy using laser beam ignition of boron-hydrogen fusion
It is not for producing nuclear material, but for reproducing conditions relevant to weapons (although HBE itself may not be useful).
throwawayaway12··on Road map to clean energy using laser beam ignition of boron-hydrogen fusion
I have spotty wifi right now and can't read the actual paper at the moment (mainly a comment to remind myself to read this later).

Quick thoughts from just reading the abstract: - There are very few facilities that do direct drive ICF (LLE in USA) -I am curious if the looked at hydro instabilities and preheating in this study

throwawayaway12··on Cities with Uber Have Lower Rates of Ambulance Usage
>I understand that healthcare is more expensive than food for all those reasons. What I don't understand is why there can't be a market for it. Expensive services can have markets too.

At the moment the only thing I can think of that are expensive services are also luxury services. Most people consider health care to be a basic service that should be open to those who need it, regardless of wealth.

throwawayaway12··on Earthworms can reproduce in Mars soil simulant
I think it is still an open (and hotly debated) question on if planets need magnetospheres to retain an atmosphere.
throwawayaway12··on Student Loan Debt Is Now as Big as the U.S. Junk Bond Market
>Comparing a college education to K-12 public education doesn't make sense. In general, one needs to understand some mathematics up through Algebra and have some reading and writing abilities to be an employable, productive adult. Whether the public school system in the USA does a good job of providing a basic education is a different discussion.

It does seem like this baseline understanding does shift with progress though. For example our ancestors did not need a lot of education to push a plow, but more education will be needed with the continued elimination of physical labor.

throwawayaway12··on Against a Tax Increase on Berkeley Students
I think it is important to emphasize that 'no tuition' is the norm for STEM fields, and not necessarily for non-STEM.

I will rephrase the scenario slightly: The university collects tuition on PhD students to recoup costs in education. This can be for paying professors (who teach the courses and advise the students) to paying electricity the student uses when doing their research. Getting a PhD is a questionable decision in terms of finance for the student. Advisors are able to write into grants support to pay tuition for students. This makes it easier to entice talented students to work with said advisor and get a PhD, rather than joining the workforce straight out of undergrad.

throwawayaway12··on Plasma optic combines lasers into superbeam
The plasma at the end of the laser path is usually the best part. Even then, things like laser-plasma instabilities (LPI) can have devastating consequences.
throwawayaway12··on Ask HN: How and where can I publish my research on AI as a college dropout?
To be fair, only a few of these sound like actual problems.

>The only person who would read a journal paper and say that the the author has good writing skills is another academic. No one outside of the research community would look at a typical journal paper and claim that the writing skills demonstrated are "solid".

Scientific papers are written for people in the research community.

>3. Trying to explain how I arrived at an expression that took me weeks to derive was discounted and I was told to remove it by my advisor: As long as I wrote the starting point "any competent researcher should be able to derive it" (hint, probably half cannot).

This seems very context dependent.

>4. Writing any background so that someone who is not already an expert can understand was strictly forbidden - always guaranteed to get a complaint by some reviewer or another. If it appears in a textbook or in another paper, do not think about including it in your paper. As a result, the only people who can understand your paper fully are those who have happened to read the same textbooks and papers you have. A poor new graduate student may need to look through several papers and a book or two to get the background needed for one section of your paper, even though you could have explained it all in a page or two. But nope - they may have to go scan over a hundred pages of material to have an idea.

The poor new grad student should pour over multiple papers to get a solid foundation of the field. Most researchers do not want to read an epic tome to figure out how your research is novel.

I agree with your first two writing points though.

throwawayaway12··on How to Live Without Google
While this is true, I think (but do not know the stats) that people buy/replace phones more often than they buy PCs.
throwawayaway12··on PhD Productivity Strategy: Do Deep Work in Less Hours
I largely agree with this, but in some fields I also think it is an over supply of PhD problem as well.
