This might be a valid theory if facial recognition was a single niche product made by unsophisticated or under resourced developers. That's incredibly far from reality though. There are many well funded groups of serious professionals and academics working on facial recognition with data sets of millions of faces.

It's just objectively not correct and not reasonable to think that the reason facial recognition works better on some demographics than others is because nobody thought of training models on those demographics. If you believe that is the case, then do you think people working on facial recognition reading this blog post are slapping themselves on the forehead saying "Of course. Train the models on someone besides the dev team!"?
The less experience you have the more you should pay a SaaS. Then when you gain more experience you start using frameworks like self managed ELK stack more. If that is not enough at some point you can roll out your own.

He wasn't being literal...
It isn't /fundamentally/ conservative, it is just typically programmed to choose the most conservative (highest probability) predictions. You could integrate a liberal aspect by fuzzing the decision process to choose from lower probability predictions.

More creativity, and ability to escape local minima, but at some cost when dealing with 'typical' cases and when making particularly damaging mispredictions.
This is wildly offbase.

The toxicity, for the most part, doesn’t come from ranks. It comes from being stuck in a bad game for 20-60 minutes. Competition just exacerbates it because now ranks/points/money are on the line.

I’m talking about being stuck with an asshole that rages for any number of reasons, then decides to kill themselves the whole game to the enemy (feeding). Or people who flame you for any number of reasons.
And you can’t quit because then you get a strike for being the first person to abandon the game, with penalties for doing it more than a few times.

Being 1 person down in a 5v5 can be incredibly hard to come back against. This is also why Overwatch is so incredibly toxic. A 5v6 fight is almost unwinnable, one person throwing is enough to lose the match. Dota handles this with comeback mechanics, but that’s only if a player actually disconnects/abandons. If they stay in the game purposefully throwing, you’re trapped and out of luck. Unlike Overwatch, TF2 isn’t quite as toxic because matches consist of 24 or 32 players, meaning each person’s actions aren’t as crucial as a 5v5. You can also freely leave and join casual matches. For the majority of the playerbase, that’s fine. Ranked introduces a bit of toxicity but that’s unavoidable in a team game. It’s also unavoidable whenever you have anything at stake- whether it’s money or points, etc. That’s just the nature of competition. No one forces anyone to play ranked matches instead of casual ones.

Competitive ranks and matchmaking can be fun, but you have to balance it right. With team games it’s very difficult, but it would be the same without a global rank system. Actually it would be worse because of imbalanced matchmaking.

And for many people, that rank is -why- they play. It’s fine to not be competitive like that, but understand that a lot of people are indeed competitive like that. Ranks are an indicator of skill and time invested, and there’s no reason to take that away from people just because one personally doesn’t care for ranked or whatever. Dota still has casual mode, and it’s still toxic, because of the length of the matches and having to rely on random teammates.
The website is quite unique in terms of design and performance.
Airplane engines are gas!

Sure, small ones with piston engines. Sure. Most anything running a turbine uses Jet-A which is closer to kerosene / diesel than gasoline.

If you're leaking fuel you've got bigger problems than how to safely heat up the engine.
I think you may have authentication and authorization swapped.
It's a bit different:

In the 1990s and early 00s, automation happened mostly in manufacturing. The low productivity growth stats that stupid (mainstream) "economists" like Krugman cite to argue against people like Yang or Musk measure all labor. But manufacturing makes up less than 1/5 of the US economy. If you look at the labor productivity in the manufacturing sector alone, it's congruent with the automation argument [1].

Productivity numbers are lagging because investments in new tech need time to bear fruit. Automation of the service sector has already started and will show in the numbers soon enough. Given that the service sector is four times the size of manufacturing in the US, it will be even better for GDP and even worse for people if again nothing is done and people keep listening to those intellectual frauds who call themselves "economists."

If I trained an AI to converse/analyze/flag using the western literary canon, it would probably end up racist/sexist/homophobic/anti-semitic/religious AF--just like Tay!

I am truly grateful for this, for I believe that this is the only thing holding back our diversity/feminist/LGBTQ+/jewish/agnostic inclined silicon-valley elite from fully unleashing it upon us as a means of social control.

Of course, it is only a matter of time before we build a large enough body of literature off of the new value systems... Some of us may live long enough to be thought-policed by something programmed--partially at least--by "Harry Potter," "Magic Mike," and "Twilight."
Sorry, but I see a lot of people, kids especially, with expensive smart phones because of status not because they can afford one.
So? He is still attaching emotional value to a technology. You could say the same thing with "machine learning doesn't handle change robustly". Same meaning, different emotion.
Being a collection of commands that can be entered in a repl does not make it a text centric DSL Text manipulation in vimscript is more verbose than Rust including all ownership syntax. What elements of vimscripts design make it good at parsing and manipulating text?

I can imagine a beautiful text centric EDSL in Haskell or a lisp that integrates tree sitter to provide syntactic hooks. I don't blame vimscript for not having this modern integration, but I do blame it for being a poorly designed language and I condemn any attempts to prolong its life. Over in NeoVim land treesitter is being integrated. Once it lands someone should write a EDSL in the Lua lisp.
... or the full Android software stack.
At the same time, I think it is unethical for a doctor to continue prescribing medications that they do not believe you actually need based on your current health.
To them/me, it would be malpractice.

If you were on an antibiotic for strep throat, finished your course, and then asked your doctor for more of it without any symptoms, should they prescribe it again? You wouldn't cause grave harm (unless the aggregate risk of super resistant bacteria counts).

All of this shouldn't be conflated with patient centered care, though. I too agree that the patient should be in charge and the doctor should be there to support. But it shouldn't mean that doctors have to do whatever the patient asks of them.
Maybe the pure science of ML is descriptive and not prescriptive. But if the rest of the world uses ML prescriptively in application, then in practice it's basically prescriptive.

It's a bit like dictionaries: they "learn" the current meaning of words. It gets annoying though when everyone starts running around policing the meaning of words based heavily on that dictionary: it would conservatively restrict the natural evolution of word meanings, when we know meaning of words do change over time, and sometimes should change over time.
I think you’re confusing certainty with authority. None of the things you mentioned are proved (certain) by religion, they are simply stated by authority as being true (though they are not) and accepted by some as being so. Saying with great conviction that Russel’s teapot orbits the sun, though no one can see it no matter how hard they try, or how powerful a telescope they have, does not make it true.
Did they remove multi profile login?!

You used to be able to login with several accounts and switch between them similar to virtual desktops.

>If the point is to be reachable by a loved one in an emergency and nothing else, this seems like a reasonable option.

$350 is not a reasonable option to be reachable by a loved one when a brand new Nokia 3310 is like $60 and can do standby for like 3-4 weeks with a single charge.
The fact that smartphones, which didn’t exist decades ago, are now afforded by everyone, contradicts the assertion that productivity gains are captured by a small class/group, and demonstrates why looking at nominal measures of income is an incomplete picture of increasing productivity and wealth disparity.
It has taken me a long time to internalize that grief is not a “bad” feeling, but rather just an uncomfortable one. Until I was fully willing to experience it, instead of avoid or ignore it, I was completely unable to move on. Grief is indeed strange.
And when part of your team's responsibility is fighting to keep pornography off your website? Snicker like a child when it inevitably comes up and go "so unprofessional!"? Or act like an adult?
The in-game incarnation doesn't have to be as weak as the real-life one. It could be based on the same technology, but with a fantastically higher fire power. Because fiction.
I think the idea of ML as “unaccountable black boxes” is a bit of a bait-and-switch from the problem being described. The problem is that ML has no political biases, it just minimizes some loss function on the data you give it. So it can’t correct for implicit biases in how that data was collected, or how the model’s outputs are used.

If you fitted a decision tree to predict recidivism risk, it would be extremely easy to interpret. But if black men are rearrested more often in your dataset, then black men will likely have a higher predicted risk on average—no matter the causes of that feature of your dataset.
Papertrail/Timber.io - cheapest way to aggregate logs and has simple search functionality.

Scalyr - my personal favorite. Just a little more costly than Papertrail, but can do as much as any full service SaaS - powerful queries, dashboards, and alerts. Takes some practice to learn, but their support is very helpful.

Sumologic - Fully featured log agregator. It works pretty good but their UI is super duper annoying. You have to use their tabbing system on their page, you can't open multiple dashboards/logs in multiple browser tabs. For the money, I personally prefered Scalyr, but this is a reasonable option.

Splunk - a great place to $plunk down your $$$$. I think their cheapest plan was $60k/yr, but I will admit that it was easy to get going and use and also had the most features. It's not a bad bang for your buck as long as you have lots of bucks to spend.
Also, aren't facial recognition algos trained on broadly available data sets...

They should be, yes, but those training sets can have biases too, and if you use them your app will have the same biases. There are moves to make things like diverse data sets for this exact problem - https://www.theverge.com/2018/6/27/17509400/facial-recogniti...

A sample of on average five people seems to be a dumb way to train facial recognition - whether diverse or not.

I was talking about testing rather than training. You can train your facial recognition model on a diverse range of faces, but if you only test it on a few faces you don't know if it works for diverse people.

Teams of developers who test using their own data (eg faces) and nothing else is annoyingly common.

I enjoyed Life 3.0 by the same author.. reviews will be appreciated.
Not the same tech, unfortunately.
The incentives of engineers building facial recognition have nothing to do with whether or not the model can recognize the particular faces of the team members. I don't believe this argument that the reason that facial recognition is racially biased because of the race of the team members. The reason that I don't believe this is because it is written about so often that there will have been many engineers who have built models with training data sets equalized by race to eliminate this bias, and yet the difference persists.
It depends on what goods you are looking at. Sure, people can "afford" an iPhone but where I live a modest house costs around 14x median full-time male salary. The wealth inequality is from a small number of people capturing all this wealth.

40% of Australia's population live in either Sydney or Melbourne, and these two cities are among the top 5 least affordable in the world [1].

I suspect that there is indeed no winning, and that under such circumstances every possible course of action is likely to be perceived as racist by some number of people. This is because the population at large doesn't seem to be able to agree on what the word actually means (https://slatestarcodex.com/2017/06/21/against-murderism/).

Regarding ML based predictive policing specifically, it seems like a spectacularly bad (but efficient and statistically effective!) idea to naively apply a machine learning based classification approach to such a problem.

Thank you for taking the time to write a thorough and considerate response.

Ask HN: How do you track and share your data reports within your team?

Any advice?
The Ryzen 9 3950X is about half the price and almost as fast (single core). For sheer performance, there’s not much marginally faster for a reasonable increase in price. (3970X is 2.5% faster at 50% more expensive, the EPYC 7742 is several times more expensive but not significantly faster.)
yup, also my favorite of all the saas platforms.
> Focusing on efficient learning means getting away from outdated methodology like tests, long-winded lectures, and more.

I think efficient learning would need to be always in the sweet spot - not too difficult and not too easy. Most courses have accessible first few lessons and then suddenly ramp up the difficulty without proper support.

Imagine you want to climb down a building. If you take the stairs, it might take you a few minutes but you reliably get to the bottom. If you try to escalate the wall, or do it in a few large jumps, you might never make it. The next step should always be the size you can handle.
The best way to avoid fraud is to become smarter oneself. It is not that hard to detect once you learned some survival skills. Sorry, but criticising someone as disrespectful for helping people to learn survival skills sounds damaging. A little like not telling your children about sex and condoms because you don't want them to have sex.

Shit will happen. Better be prepared, and better help others prepare. Stop criticizing people who try to help.

PS: He also didn't say that it isn't fraud. He said that besides fraud there are a lot of other ways a video you made could be used in other ways than you intended.
It's convention to be extremely transparent about edits because of irritation with people who change their comments after being replied to, making the replies look irrelevant or incorrect. The only way for people to know about an edit is to see that comment changing. Sometimes you'll see allegations posted about surreptitious comment editing. It's just easier to always say you've edited.

Unless you want to be in some way compatible with Emacs, elisp is not a language I would use. Anyone who has written any non-trivial amount of elisp knows this.

There are other lispy languages, that are easier to embed without many of the warts of elisp. If you really want to have elisp, you have 3 ootions:

* Implementing it yourself
* Trying to break elisp and Emacs apart (not likely)
* Using guile's elisp implementation. It is complete and all that, but then you should just use guile scheme instead.
Or Guile.
I've patronised the Atlanta (Gwinnett) store since the mid-2000s. It was a very important base for hardware of all kind, to the degree that we would regularly drive from Athens, GA (60 mi E) to Fry's for parts. The last few years, it's been a gradual deterioration toward exactly the kind of empty-shelf phenomenon described in the article. By now, much of the stock seems to be gone, what remains--which is definitely not the most updated and trendiest items--is disorganised and poorly attended-to, and the place has almost no staff. One can hear a pin drop in there most days. It's eerily still, bizarrely empty yet formally open, like the setting of a postapocalyptic video game.

Last time I walked in there was a few months ago, and I assumed they were just trying to clear out what remains of inventory before closing the store. It has been very unclear to me under what economic principle it remains open, given that there is little merchandise, almost no staff, and no customers.
Your point about convergence to the exact minima over training loss not guaranteeing the best generalization loss reminds me of the point made in this lecture here https://www.youtube.com/watch?v=k3AiUhwHQ28.

You also made an interesting comment about work not catching on outside of the optimization community - can you recommend some resources or websites to follow in order to see what the optimization community is working on? I've developed an interest in the area but don't really know where to go for "up to date" information.
I would call naive bullshit.

First of all, without real-world, not imaginary adoption the sentences like "lift hundreds of millions out of poverty via cheap, non-predatory financial services" are nothing but literally empty memes.

Second, the projects like https://iohk.io/ are way superior than current Ethereum in any dimension except that, and this is what makes it still alive, Ethereum is here for many year.

Other than that, Ethereum is an amateur hobby project, badly designed by an uneducated amateurs, badly implemented by inexperienced amateurs, and has been obsoleted by literally tens of world-class teams.

That iohk folks, for example, has been smart enough to employ (as research fellows) world's top experts in relevant fields who have produced world-class solutions way above any amateur crap currently in use.

Even most of HN alumni barely understand what does it mean to have an executable specifications in Haskell (guaranteed lack of contradictions and guaranteed correctness of implementation) and verified by a proof-checker on-chain language (guaranteed soundness of the other-peoples's code)

Nevertheless, it seems that there is literally no demand for adoption of these already up and running world-class top-tier solutions (by iohk) given that there is literally nothing better, nothing even close. Why? Because, it seems, that no one is interested in anything but speculations and memes.

You literally have no idea, my friend.

Do the makers think that there's a sizeable portion of people that hate their iPhones or Galaxies and want to spend $350 on a phone that doesn't do things? Doesn't do social media, doesn't do email, doesn't do news. Most consumers would at this point ask "What's the fucking point?"

Smartphones are popular because people want to do the things that they enable. You probably need to live in some sort of a niche social circle in order to justify $350 just to be able to tell people how your minimalist phone is not able to browse the Internet.

If you just wanted to have a basic phone that doesn't do a lot of things, you could buy a Nokia 3310 for $60. You just don't get to brag about your disconnected way of living since the Nokia 3310 can actually do those things.
I see a few issues with your more expansive statement. And upon consideration, also with my original statement.

1) Who and what defines "critical"? I limited my statement to medical software which is already regulated and where there are product sales.

2) I think automotive should also count. Is any automotive software currently regulated? I assume so.

3) "Open source" is only triggered on the distribution of software. If I buy regulated medical software, or buy a car, then that should count as a distribution. But "ICBM" is different. The government buys the software, but there is no compulsion in 'open source' to distribute the software more widely. Which means there's little practical difference if the software were required to be open source.

Similarly, only those who buy Boeing planes would have access to the Boeing software, not passengers or the general public.

Does the US "sell" ICBMs to other countries, or just "loan" them the systems?

4) The flaw in my original statement is that the software can't simply be "open source", but the license must also prevent 'Tivoization'. Just because I buy and have a pacemaker installed in my body, and the software is open source, and the hardware is updateable, that's not enough. I also need any security keys needed to install my patched version to the hardware.

5) Lastly, the software for dark-pattern ads isn't distributed to those who view the ads, so "open source" doesn't gain anything.

I agree it needs more low level controls. The api is very high level at this moment. Luckily that seems to be a focus of webrtc NG being discussed.
