I do see two. I'm not sure the third you're referencing:

http://www.pnas.org/content/111/28/10107 - This is the exact sort of study I was referencing. It only shows that there is a different in result, not opportunity. It further shows that as the baseline competency standard increases (up to labs being operated by Nobel Laureates) - so does the "bias". It proposes explanations for this being either self selection by women, or bias by men. It ignores the most likely explanation which is that though the pool is split about 50/50 by gender, competencies are not.

http://www.pnas.org/content/109/41/16474.full.pdf - I was familiar with this study, and it's a good example of the ongoing issues with social psychology toy study. For reference the replication rate in social psychology is now at around 25%. Put another way, if a social psychology study tells you something - you'd generally be vastly more well informed if you assumed the opposite, or at least assumed what was stated, was not true!

This study offers a demonstration in a number of ways this has occurred. One major issue is that there was no effort to manage a response bias, other than in broad characteristics (race/gender) of applicants. Corinne Moss-Raucin [1] personally mailed a number of faculty asking them to respond and rate a variety of potential students. One glance at her faculty page will tell you what she's actually doing. So who voluntarily opts into this? In total just around 30% of contacted faculty chose to. I think there is a 0% chance that this is not a biased sample.

The questions were also framed in a context that seems to imply a potential personal "affinity" for an individual. One important nuance here is that the students offered up for consideration were all low quality. The questions to demonstrate bias included:

- "How likely would you be to encourage the applicant to continue to focus on research if he/she was considering switching focus to teaching?"

- "Would you characterize the applicant as someone you want to get to know better?"

Do you think you'd try to keep low performing Jennifer in your office, even if she was looking into teaching instead? Would you like to get to know her better? I mean come on this is just absurd, and a reason that the social sciences and especially social psychology is imploding in on itself. It's like if the "biases" went in the opposite direction our researcher was ready to write up an article about unhealthy professional attitudes towards females and female independence.

> I haven't tried qutebrowser, does it have extension or RSS support?

It has a userscript:

https://github.com/qutebrowser/qutebrowser/blob/master/misc/...

... but extensions in qutebrowser are admittedly in a very early and immature state now, and the codebase for them is going to be changed.
It does make some sense. Yes, technically, the bias is still there, but it's lower. Getting some accuracy on image detection isn't that difficult, but making it more and more accurate is. Going from 50% accuracy to 51% is much easier than 98% to 99%.

Of course, with the error rates reported on certain groups a human making the final decision is not enough.
> The one (?) remaining charge in Sweden will quickly fall apart no doubt.

There is a lot politics to decide this depending on american, UK and Swedish diplomacy. Everything which should not exist in a legal system.

> Aiding in defeating security measures to obtain it is quite another story.

Conspiring to assist in defeating a security measure. There are plenty of precedent of cases where a person has been charged with attempting to break a password, for both in UK and US, and the expected punishment for a person with no priors is a fine.

> Assange lost all credibility as a journalist over the Wikileaks handling of the 2016 election and related hackings (eg the DCC emails).

People can change when they receive death threats, talk about drone strikes by people in power, death penalty and secretly being throw into Guantanamo.

> Playing an active part in illegally obtaining emails and other materials

The current accusation of offering to help to break a password does not cover that. Getting leaked email sent to them is no different then getting leaked the audio log of someone being recorded without their knowledge.

> Even Snowden filtered his classified material through reputable media outlets.

"reputable media outlets" do not carry the same moral meaning as they once did. The Guardian journalist Claas Relotius is a prime example of reputable media doing less than reputable behavior, and the majority of news papers in the US is own by a handful individuals which endorsement has significant effect on the polls. A lot of media research acknowledge and sorts news paper by political bias. For source see https://cyber.harvard.edu/publications/2017/08/mediacloud
I don't know whats going wrong with Firefox. Im still an active firefox user. I intentionally avoid Chrome and use it rarely to see if the site which doesn't work in Firefox also doesn't work in Chrome. IMHO Firefox didn't make me feel slow anytime. The whole point of Google Chrome automatically logging-in as Gmail user throughout the browser should have sounded alarm for people who care about privacy. I do agree Google brings latest of web tech to Chrome fast, but that makes other browsers falling behind in terms of features. Catching up wastes lots of time for the other browser makers. IMHO monopoly in browser is not a good idea. We know what a monopolistic attitude brings to plate. Also, when we see new extensions for Chrome with an explicit subject as "extension for Chrome", for Firefox users it feels like being sidestepped. Then it becomes the onus of the Firefox user to see if he/she needs to get in touch the extension developer to see the possibility of portability. A caring developer shouldn't sidestep Firefox or even other browsers per se. If every developer becomes selfish about developing tools/extensions for their own environment, they are blocking the goodness to others.

Maybe worth pointing out that film has its own issues with long exposures, though. If I remember right, film's response to light isn't strictly linear with exposure time so you get less and less useful additional exposure as you expose longer.

This sort of stuff is maybe not useful in most simple systems and issues, one where "write test, fix bug, re-deploy" feels right.

But when you have tighter coupling and a lot more business rules, this stuff becomes useful.

For example, imagine that you are writing a billing system. Beyond just the code, there's a design that expects a passing of time and an ordering of operations (user signs up to the system, after a bit they will get invoiced, the amount invoiced will be right, perhaps there's pro-rating)

In models where there are a lot of moving parts and where you _don't_ really have locality of code, then this stuff becomes more useful.

If you've ever had a bug that exposes an issue not just with the code, but with the entire system and set of assumptions it's built on, it's possible that something like TLA+ could help you a lot for that system

I've used a few retina Macs to do various kinds of web dev. Firefox tends to do some things fastest (eg: re-layout when resizing the window), some things the slowest (eg: certain large, complex CSS animations). For most things, it's perceptually equivalent to Chrome or Safari. Some things that are fast/good in Chrome will be slow/bad in FF, and vice versa. The biggest shortcomings I currently face are (1) a lot of banding when layering lots of complex gradients, due to a poor job of dithering and (2) weird handling of certain colors on my P3 display due to the assumption that colors are in the full display space rather than sRGB.
SQL = structured query language. It's just an interface to access data. All relational databases offer it but so do many other non-relational systems. This means using SQL to read/write data is completely separate from having relational functionality like joins.

How come the rules that restrict Joe Biden’s freedom to touch other people shouldn’t apply to you?

There don’t need to be rules about shaking hands or high giving because those are mutually consensual actions.

Fist bumping a non-receptive individual (aka punching a colleague on the shoulder) is not consensual.

For the “vocal minority” which is most women and some men, non-consensual touching is associated with bullying, intimidation, physical coercion and assault. In the workplace we try to avoid emotional arousal because people shouting angrily at each other makes it difficult for others to focus on their work.

In social settings, you are free to explore boundaries as long as you are aware that failure to take non-vocal hints can lead to being ostracised from those social circles.

But yes, the “vocal minority” should be allowed to define the lines, which are pretty simple even for people who have never had to follow etiquette: other people’s bodies are off limits to you unless they indicate otherwise.

By all means go for the high five, but accept that if it is not returned you don’t try forcing it to happen. You have now divined where one boundary existed at one point in time.

Hi, I am from Cosmos DB engineering team.

1. This occurs when, after the connection has been established, CRUD commands are sent before the authentication command. Note that some MongoDB drivers have a bug where they are not authenticating the connection in rare cases and sending CRUD commands. Could you please check and upgrade to the latest driver of Mongoose/NodeJS-Native/NodeJS-Core driver, which has a rewrite of their client-side auth stack and fixes a lot of bugs. One of such issues is described in https://jira.mongodb.org/browse/NODE-1798 which was fixed by https://github.com/mongodb-js/mongodb-core/commit/7ffb4bbe05...

2. Resource tokens provide fine grained access control but it does require you to implement a custom token management service. We are working on support for Azure AD integration and support for custom roles and policies. The feature is code complete and should be made available soon.

3. Cosmos DB’s SQL query language is supported on a non-relational data model - which maps cleanly to document/column-family/graph. It does not support joins since (unlike a relational model), a single Cosmos container can contain items belonging to any arbitrary schema.

4. Re. API for MongoDB requiring a shard key, we are going to relax this restriction before 7/30/2019. As you noted, we do support an emulator for Windows. We are working on a Linux emulator and should be released later this year.

5. The portal was displaying incorrect cost estimate in certain cases. We addressed it and the fix is being rolled out.

Thank you for the feedback!
I think several decades from now I'd take the Boston dynamics robot walking in rather than a police officer, because the robot won't have to fear for its life, so it's less likely to use lethal force.
Given that eyewitness testimony is consistently unreliable, biased, and internally inconsistent, no, they shouldn’t. Human judgement is the best we can do so far, but it is hardly a worthwhile goal, especially with systems that take us from affecting individuals on a person-to-person level to influencing the interactions of millions of people with their government.

Algorithms can be explainable, and I agree that anything that affects your standing in the eyes of government should have that as a minimum requirement.
But the bricks won't keep the rain off you.

The data is closest to reality, but without interpretation, we can't take useful action from it.
Ask HN: Toolbox or library for simulating classical mechanics problems?
I'm looking for a toolbox or library to simulate classical mechanics problems usually found in textbooks.

I want to for example see the oscillations of a usual double pendulum problem with ability to plot angles and forces at arbitrary positions. Or physical parameters of "box on a cart with friction" problem or real-time animation of a N-body problem. It'd be nice if it also supports 3d.

1- In summary, suppose someone wants to go through Landau-Lifshitz or Goldstein books and simulate the problems on his computer. What tools should he be looking for?

2- What is the keyword I should be searching for? Rigid Body Solver? Physics Engine? Numerical solvers of Lagrange (or Hamilton?) differential equations formulations? or should I be looking for Finite Element Methods?

3- It would be great if there is a MATLAB/python/C++ solution and not a full-blown software like COMSOL

Thanks

Rural America Is Running Out of Teachers
After a certain point in a career you realize that time spent coddling and being coddled is simply wasted. As a teacher you realize that even though you can be (and likely are wrong), your job is to stand firm and be direct. If you have no concrete reason to doubt yourself, why be equivocal with someone? And if you do have substantial doubts, why would you risk poisoning the well? In my experience, good professors are both more direct but also quick to shut up because there's no good response--either because a criticism is legitimate or because the student is just being argumentative, but either way there's not much else to say that the student shouldn't be capable of figuring out themselves.

As a student you realize that instructors aren't infallible and that you're not only free but expected to accept or reject what you're told on its merits. And, frankly, this is much easier to do when an instructor isn't equivocal--when they state plainly and with conviction their beliefs. If everybody is mature enough, it's implicitly understood that people can be and are wrong. Unfortunately, not everybody is mature enough.

This is true of leadership more generally. The job of a leader is to put themselves on the line. By being direct and forceful there's never any doubt about where responsibility for an idea lies, and there's no back peddling if they didn't equivocate. It's more difficult to say that an idea wasn't given a proper defense if the defender literally puts it all on the line; where there's no reason to doubt they didn't explore every reasonable criticism.

It's the same thing with writing. As an undergraduate I hated writing papers because the thought of committing to paper an idea I was unsure of seemed wrong. But that's not the point of writing; the point is to commit to paper the best defense you can think of at that very moment, and to do so without equivocation. The criticisms can and will come, as they should. If you equivocate, however, you're softening the blows of subsequent criticisms, which is a disservice to everybody, but especially yourself. Making yourself vulnerable to criticism is a very difficult thing to do.

Especially once you get into graduate and professional studies, the professor's job is present their ideas firmly. To do anything less is a disservice to students and the truth. This is easier for some people than others. People who are legitimately unsympathetic a-holes will, of course, have an easier time at being firm. You can usually differentiate the non a-holes as they're more likely to invest more time in thoughtful, personalized criticism (e.g. 1 1/2 pages of comments). But that takes tremendous effort and patience, and even the non a-holes don't always have the time or ability to do that. The best gift they can give you is serving themselves up as a punching bag.
Yes! Thank you do much for bringing this up. I read about this book in a comment on HN many years ago and have been trying to find it, or the book title, ever since. Going to bounce this to the top of my reading pile.

Did you forget a /s there? For me the marketing around Watson, with the unrealistic and not scientifically backed assumptions about the state of AI they put out to the general public, epitomize what's wrong with how the world sees our field.

More on topic: the underlying problem with the original post here seems to be one of selection bias in the training data. Somewhat of a remnant of human decision making that, likely unintentionally, ended up in creating biased decisions in the end. While the system you linked seems to potentially create nicely decomposable decisions, is there anything that inherently prevents "bias" in what it learns? The approach seems to face many of the same problems modern ML systems in the Linked Data / Semantic Web space would given unrestricted learning from the web.
NYT has lost its prominence after esp after picking sides on several hot topic issues. The bias is way too obvious nowadays, and I personally only glance through it to see how the elite want the people to think, and then I just do the opposite lol.

The favoritism towards certain groups and the dismissal of others raises a lot of eyebrows.

These companies are still benefiting from the same government services which is what the normal corporate taxes are paying for. Saying the taxes paying for those services are also somehow pay back this free loan is very much double dipping.

On top of that, this is early stage funding and most of these companies will fail paying back little to nothing.

PS: Corporate taxes are down to 9% of the federal budget. They really don’t pay much in the way of taxes vs the services they benifit from.
