A path to learn data science
Hello. Any good books, websites, podcasts, courses etc to recommend to a Computer Scientist who wants to start learning Data Science from scratch?
Show HN: A tool to help make sure you're building the right product
The Lean UX Canvas is a concept developed by best selling author Jeff Gothelf. I was at a training course of his last year where he talked us through his canvas, and it is an amazing exercise to really focus on the problem,the solution, the users etc.

We started using lean ux canvas in my work but there was no good way to do them digitally, so I built this: https://leanuxcanvas.com
The table you linked is a little confusing because it's focused on the murders, but the offenders are more relevant to your point. It also excludes a lot of murders where information about the offender is missing, so the overall numbers seem too low.

The following table is more relevant:

https://ucr.fbi.gov/crime-in-the-u.s/2016/crime-in-the-u.s.-...

And here's the one from 2018:

https://ucr.fbi.gov/crime-in-the-u.s/2018/crime-in-the-u.s.-...

So your point stands: when you talk about "disproportionate", you need a baseline. If you choose the proportion of the general population as a baseline ratio, it looks like police violence disproportionately hurts blacks. But if you choose the proportion of known murderers as the baseline ratio, it looks like police violence disproportionately hurts whites.

Note that there is a subtlety here: the baseline ratio is simply a ratio to use as a comparison point. I am in no way implying that all people killed by police are known murderers. Nor am I saying the ratio of known murderers necessarily extrapolate to the number of justifiable-use-of-force incidents.

EDIT: I am really just saying the baseline expectation matters, and that the general population is not the only meaningful baseline. I am not saying which baseline is the "right" one. That depends on which specific policy you are considering.
I wish they hadn't chosen colour schemes that seem intended to bias the reading. In the first infographic, white characters are very low-contrast while brown characters stand out. In the other, both seem to be about equal in terms of contrast.

That said, I'm not sure how to get this kind of presentation right, since the "white" population is not the same size as the "black" or "brown" population. They say a black person is almost four times as likely to be arrested for drug offenses as a white person. While I think their graphic seems a bit manipulative, at the same time it doesn't seem to capture the real awfulness of the situation. Non-Hispanic whites are something like 60% of the US population, while black people account for 13%, so just showing drug arrests by skin colour paints a very rosy picture of the actual situation.

My suggestion, normalize contrasts and weight the number of characters by demographics. It'd be pretty shocking and would avoid this odd whiff of dishonesty.
You could run Android apps on Blackberry's ill-fated Blackberry 10 OS. A lot of the apps in the BB app store were repackaged Android applications (while developing BB10-native was easy, in terms of market it was a no-brainer to do an Android version and repackage it for the BB10). QNX was (and is) a rock-solid OS.
Startup investing isn't private equity. Private equity is acquiring a profitable company with limited equity and a pile of debt, paying it down, and selling it at a profit.
>And how in general, do you think you resolve a chicken-and-egg problem where people dispute responsibility

Not sure exactly what you mean here.

>Then you suggest poverty might be to blame, but you doubt it.

I don't necessarily doubt it, but I find it curious that there is not a universal poverty == violence.

I think reducing poverty is more of a solution than blaming the police, I apologize if I wasn't as clear with my statement on poverty.

My hypothesis is something like this: I doubt police cause violence in communities (except perhaps violence against police). There seems to be a correlation with poverty and violence, it's not universal. Picking a group based on skin color and saying "we reduce this poverty and not other kinds" is fairly immoral, therefore the experiment is to flatten the problem of poverty and control to see if there are spikes of violence across this flat plane and to see in which communities it occurs. That would help to isolate a potential root cause of violence. Other experiments could be done.

I'm pretty sure the causality is baked into most people not being an expert in statistic, hence "simple" statistics. If the police are running a really basic pattern matching algo, the line between correlation and causation may not be perpendicular. What I mean is that if the situation on the ground "community A has % higher violence" then in situations interacting with A implies higher chance of % violence. The causality is reached because of the simple understanding. At least that's my take.
It's worth noting that some people specifically see verbal communication's undocumented-by-default nature as a feature.

When I was younger I found that idea very offensive. I considered people who held that viewpoint to be suspect (engaging in political machinations, or using fluid recollections of conversations to their advantage). I still think there's a grain of truth to my suspicions, but I've learned to recognize that there are acceptable reasons for undocumented conversations.
I would venture that the problem with Google's products is that they run in the browser and in spite of all the improvements in browsers these days its just not ready yet when you need the kind of quality and performance that huge meetings demand.

Also and perhaps more importantly, Google's approach is tied into its own ecosystem but anybody can join a Zoom meeting with just a link/code. Google had everything they needed but are too tied into the everything on the browser mindset and their own ecosystem to see they're shooting themselves in the foot before their horse is even out the door. At this point its too late, Zoom's aggressive pre-marketing, simplicity, and ubiquity is a real force now and everyone else is just playing catch up.
Just the existence of mass movements like the above(which is not isolated) refutes the Buddhism -> karma -> fatalistic acceptance that was postulated in the first comment try to establish a link with tyrannical governments.

Just living in any of these countries, one will see the constant effort of people, even hustling, to get ahead in life, far from any fatalistic conceptions one might have about their life.

I can, in fact, think of other examples of worse brutality, even in the last few centuries, for instance the American slave system and treatment of labourers in Congo. Not quite the same extent, but still terrible, the British had an indentured labour system transporting Indians whose local lands were devastated by colonial rule. I wouldnt casually attribute these to religion of the westerners.
I have seen these videos and highly recommend them especially for people like me who want to get a sense of the traditional control theory literature, have seen similar concepts elsewhere and are trying to map the motivations and notations.
That’s “common” based on what judicial precedent. What makes Peter Thiel’s opinion more relevant than any random HN poster who doesn’t know what a monopoly is?
The program has no such contract with the OS. The only contract is that if you access unmapped memory, you get a segmentation fault, and the relevant signal handler is invoked. The default signal handler terminates the program.

Depending on the program, a segmentation fault may be routine. That’s why it doesn’t make sense to call it a violation.
I wasn't meaning to suggest that only provably true speech should be protected. Certainly for libel/slander/defamation you have to prove that a statement was untrue to get a judgment against it.
What is the actual return of the project itself though? You could also print money to build a tower of babel and it seems like the same general benefits would apply.

> Which supermarkets would do if they could

They can, and they do. Here[1] is a random example of applying that to a supermarket (the other pages on that vendor's site shows some of the other ways the tech can be used).

Solutions tend to use a mix of video camera data and cellular data (wifi and bluetooth beacons[2]) to track in-store movements and behavior.

Done well, they can also connect individual store journeys to specific point of sale transactions, and understand hoe variations of in-store behavioral patterns ultimately influenced actual transactions. Which opens the door to running in-store optimization experiments very similarly to how you'd run A/B optimization tests for websites/apps.

People disagreed, so I gave these examples.
Ask HN: Website listing/explaining common Python pitfalls&tricks?
Is there any site which has a good list of things that programmers that come from other languages have to pay attention to, respectively, that lists some (useful) tricks that are commonly used?

Examples:

1) I think that I remember (I might be wrong) that once I was passing a "list" to a function and that when I manipulated the "list" in the function itself (by removing/adding items) the "list"-variable outside of the function got the same changes (I didn't expect that as I thought that the list-variable would be copied when passing it to the function).

2) When using the "multiprocessing"-module I thought that I managed to create a shared "list"-variable that could be read by all sub-processes, by declaring it outside of the function which was linked to the sub-processes. I'm sure that technically it did work, but I'm not sure if it was just by luck or what (anyway I think that Python v3.8 now officially supports shared memory/variables?).

3) I kept creating strings like 'The value of the variable is " + str(myvar) + "blablah"' and I read all the time that that was a performance problem but recently I read as well that that's not the case anymore => conflict :(

4) I recently read in an article referenced in HN that doing "my_str = str" in a function and that then using "my_str()" instead of "str()" is faster (somehow because "my_str()" is then "local", but didn't understand the exact implications) => is this something normal to do?

Thanks :)

Ask HN: How do you programmatically delete Facebook activity?
I spent quite a bit of time looking through old HN posts, exploring extensions and researching online.

There's no up-to-date information.

I found how to delete things (searches, likes, posts and etc.) one-by-one. But how do I delete many years of this stuff?
Sorry, I did a poor job of making my point.

@hkarthik implied that it's impossible to use technology and also boycott Apple and/or Google. I agree with them.

You seemed to disagree by saying that you do boycott Apple and Google.

The point I was trying to make is that you're part of their revenue stream even if you yourself don't have any consumer relationship with them. That's why they feel like a monopoly to so many of us and why we criticize them rather than leaving their ecosystem. We can't leave their ecosystem!
I wondered if maybe he'd posted something else in the blog and I think I found it. Something about bad style, too few details, and something about contributing to bad norms?

https://www.lesswrong.com/posts/QePFiEKZ4R2KnxMkW/posts-i-re...

""Taking Ideas Seriously": Stylistically contemptible, skimpy on any useful details, contributes to norm of pressuring people into double binds that ultimately do more harm than good. I would prefer it if no one linked to or promoted "Taking Ideas Seriously"; superior alternatives include Anna Salamon's "Compartmentalization in epistemic and instrumental rationality", though I don't necessarily endorse that post either."

Then I don't understand who this question is supposed to be directed at:

My answer would be that none of the activities you list (with the possible exception of the kind of wannabe entrepreneurship the paper is talking about) are conspicuous consumption. But it seemed like you were directing the question at the authors of the paper, not me.
Microsoft was never required to allow multiple search engines. Nor were they required to allow other default browsers in the US.

This in interesting. I've been wanting to make a neural piano synthesizer for an electronic keyboard that outperforms the sample-based stuff Yamaha and Kawai use. But getting labelled training data is a problem. Would be interesting to use a setup like this to amass loads of accurate training data about what inputs produce what waveforms!

If the author is willing to mic up the piano properly with a good mic, and publish a few hours of uncompressed samples of piano playing along with the associated MIDI files -- it doesn't have to be good playing, but preferably better than "random" playing, it would be super cool to play with that data.

This whole 'software as a service' thing has really gone too far when things like drivers are being sold on a subscription base.
That implies Android is not an OS, but an API and a set of services running on top of a Linux-based OS that's embedded on each and every Android device ever sold.

There's still phone calls. Any co-worker you trust enough to have an "off the record" conversation with wouldn't turn down a "hey, can I call you?" request. They might think it's weird at first, but would understand later I'm sure.
Yes, and between Android and iOS, Apple and Google have captured ~98% of global the smartphone market in 2018.

Apple accounts for roughly 47% US market share to Google's 52%. Apple's app store generated 33 billion of the total 57.4 billion in revenue in 2018, with Google taking the rest.

They both operate app stores in very similar models, and both of them clearly need attention.

Just because two competitors happen to be splitting the profits from abuse doesn't make it any less of an issue.

I wish them the best while operating a distribution and marketing channel. I think it should be entirely illegal for them to prevent other channels from being created and installed on their systems.

To be clear - this is the definition of cartel behavior. They both operate walled gardens precisely because they know it makes a 3rd party breaking into the market an astonishingly small possibility, and they have both carved out a marketing strategy in the US that mostly doesn't overlap.

I think it's because they just launched a new moonshot venture fund? Though in that context I'd be more curious about what they find different between researchers and entrepreneurs since presumably, they want to turn a lot of the former into the latter. What'll they have to do to bridge the gap and make their venture firm a success?
Yes, bankruptcy is an option but it's not the end of the world. Maybe forming an LLC is the way to go in these cases where you are trading non-insignificant amounts of money.

Nothing convoluted about it, plug in memory stick, enter password, run script, unmount volume chuck in bowl next to PC.
I think it comes down to the German attitude towards risk and entrepreneurship. Failure is still seen as a permanent mark on your CV here instead of something that gave you experience. German VCs are risk averse, so they are not taking big chances regularly which could create unicorns. The few newer VCs that think and act more "American" are to small to fund unicorns.

Is modularity a huge benefit when most languages allow you to compose applications into modules which have keywords to enforce encapsulation?

And scalability seems like an incremental benefit at best. If you're cpu bound you can load balance without microservices. And if you're database bound (and have already cached, optimized, and scaled up your db) you can scale up your db to multiple instances. Even Stackoverflow runs their entire infrastructure on just 4 db machines.

I would say the most important part, and where every company has shot themselves in the foot is the need for an account. With Zoom you can join meetings with just a link/code, and while it may seem trivial to us thats a huge plus for nontechnical people.

That and the fact Zoom had seamless integration with large meetings with relatively little-to-no performance/quality costs is a huge benefit. The luck of timing & advertising is what pulled it all together.
And Amazon has a monopoly on Kindle apps and Spotify has a monopoly on music that can be played on its platform.

There does seem to be a glut of net-negative "entrepreneurship" resources like low-quality bootcamps, pay-to-pitch events, useless networking events, endless motivational/advice content, etc. Many of these are specifically targeted at convincing people to "live the dream", although I suspect they're more misguided than intentionally scammy.

Actually, when one deliberately obtains the power to design the audience those who helped to establish this are by definition not the design you are looking for. At first the useful idiots must be portrayed as model citizens and as majority opinion (by silencing everyone else) then they too need to be silenced to preserve that illusion. You don't want subjects who have reason to praise you, you want ones who praise you because they are your subjects.
