> Why would that be wrong?

The issue is that modeling B with a distro centered around 2.5% ignores what we know about the historical conversion rate (2.0%) and the control bucket's conversion rate (also 2.0%). If our goal is to make the best estimate for the future that we can, we should take this data into account when evaluating B. As a thought experiment, imagine that you have A at 2.0% and B at 2.5% conversion for Week 1, with a historical conversion rate of 2.0%. Someone says they'll pay you $100 if you correctly guess what B's conversion rate will be next week, either (i) in the range 2.0% to 2.5%, or (ii) in the range 2.5% to 3.0%. I'd prefer to bet on (i) than on (ii).

> What would a Bayesian conclude instead?

One simple approach would just be to start with a more informative prior, like Beta(2+1,100-2+1) instead of Beta(1,1). This would pull bucket B's posterior distribution closer to 2.0%. Another approach is to use a hierarchical model [1], which will fit the individual buckets' priors for you.

The article "Letting Kids Light Matches and 9 other seemingly scary things that German parents do" [1] provides the point of view of an American mother on parenting and schooling in Germany.

You are not correct that it is all in the drivers.

The Intel GPUs just do not have the FLops to complete with the high end offerings from NVIDIA and AMD. Here is a realistic benchmark of GPUs and notice that Intel isn't even listed in the first page, that is how slow Intel's GPU is:

It needs... robots.

Robots for all the things that a commuter doesn't directly interact with.

The humans belong in the human interface and can remain in the stations; MAYBE as actual patrols on the train looking to provide assistance and keep the peace (and also having access to get in to the control area in case an over-ride is required).
I quickly found this, it looks like its based off a conference presentation but know there are older sources saying about the same:

> "So far, the results have been dramatic. Among 4,000 people tested so far in the Imaging Dementia-Evidence for Amyloid Scanning (IDEAS) study, researchers from the Memory and Aging Center at the University of California at San Francisco found that just 54.3 percent of MCI patients and 70.5 percent of dementia patients had the plaques.

A positive test for amyloid does not mean someone has Alzheimer’s, though its presence precedes the disease and increases the risk of progression. But a negative test definitively means a person does not have it."

https://www.washingtonpost.com/national/health-science/brain...

What they do is use a circular definition of:

Alzheimers symptoms + amyloid-beta = alzheimers disease

Alzheimers symptoms - amyloid-beta = other disease

So I don't disagree that technically "everyone with a confirmed AD diagnosis had amyloid build up", just that this is true by definition.

> Since I don't want to tinker every weekend with my distro anymore

Do many people actually do this, though? A few years ago, I used Arch as my main distro, and, besides the initial setup, almost never tinkered with it. I would imagine that more approachable distros would be more tinker-free too.
Which can be directly attributed to Dirk Meyer’s personal and technical team leadership. I highly doubt Jensen would have pursued the same course.

I’m not an Nvidia evangelist or anything, but one has proven results and the other only has failure after failure under their belt.

Workman vs. Colemak probably isn't a huge gain. However, either of those have a huge advantage over Dvorak for someone who doesn't already know Dvorak and knows Qwerty, because they're just not that different from Qwerty the way Dvorak is. They also preserve the left-hand location of C, V, and X since those are so commonly used for cut-and-paste operations.

Again, this is coming from someone who's proficient in Dvorak, but not Colemak or Workman, but right now I would not recommend Dvorak to someone interested in trying an alternate layout; I'd point them to these newer alternatives instead.
Cite a case. Griggs v. Duke Power is what most people claim makes IQ tests not legal, but that's not what the case was about. It was about discrimination against blacks, which is a legal protected class. Intelligence is not a legal protected class, so this ruling does not impact such tests for general intelligence.

>there also needs to not be a less discriminatory alternative available

This was to prevent discrimination against blacks (if you're using the case above), not for intelligence. It's perfectly legal to discriminate based on intelligence, however you want to measure it.

>once the unequal impact is proven

Only against protected classes. Intelligence is not a protected class. Here's [1] the EEOC list of allowed testing. Top of the list is general cognitive tests.

So, what case are you basing your claims on? Are you conflating discrimination against a protected class with discrimination against intelligence?

The use case for ReactOS is going to occur soon, or already is. And that's supporting older peripherals on new machines that cannot run Windows XP. Right now I've got a failing computer with an audio interface that doesn't have Windows 10 drivers. Upgrading to a new machine would require a new audio interface. But with ReactOS I'd probably be able to keep using the existing drivers. (As it is, the card is still supported on Windows 7 so I'm using that.)
Does sass drive us away from the 'program it once' attitude?

Intel's OpenGL drivers were traditionally quite buggy and tended to lie about what features they actually supported in hardware.

So depending on the execution paths you could even trigger software rendering by relying on wrong assumptions.
Of course there is a minimum standard - but the problem is to have effective censors you need to give them a degree of leeway/self-judgement and in a politically charged environment this will lead to bias.

An experienced web engineer, product strategist, and designer.

After working in several startups I’ve had the opportunity to do a bit of everything. I’m a 10x engineer on the front-end and experienced in video game production. I'm looking for a role that focus on creative vision, marketing -- and some heads down programming when needed.

Let's build something amazing!
In Izik's tablet interface, each category was a separate row of results. So in this example, there would be 2 rows, one for automotive parts and one for games, and if you scroll horizontally in a row you get more results in that category.

I think that's what you meant by partitioned results.

Google computes this internally but I've never seen them use it for anything other than having diversity in their top 10 results.
I was at Google and they did buy offsets from 2007 until after I left. Not for Oregon, sure, but definitely for places like the Carolinas (our good old friends at Duke Energy...). It was only in 2017 that they covered 100% of corporate/datacenter electricity with actual contracts.
I like 'stgit' for this -- it lets you manage a work-in-progress patch series as a stack of patches you can move around in, update, reorder and so on, which I find more natural than raw git rebases.
It's ongoing work for me. Lately I've been digging through a lot of gene expression datasets to try and figure out which genes are the most overexpressed in aging tissues. I then use bioinformatics tools like clue.io to figure out which OTHER genes regulate them, and also possible drugs.

There are a number of pathways that seem to be downregulated by purigenic receptors, many of which are sensitive to adenosine. Caffeine blocks adenosine receptors and blocks signaling.

What could be happening here is suppressing inflammation, since evidently purine nucleotides activate some immune cells.

> When I grew up having a computer was a big thing and we certainly didn't have one for each person in my home we had a family computer which i think cost around 1K in 1995 or around 1700 adjusted for inflation.

Fair enough, and I see your point. The first computer we got arrived in my house the same year, but we used to run windows 3.1 on that thing, and it certainly didn't have different user for different members of the family :)

also, my father was so scared of me and my brother screwing up, that, when given the opportunity to have Windows 95 he installed it on a different partition and we dual-booted windows 95 and 3.11. Me and brother were only allowed on dos/win3.11. I doubt it was a sound idea, technologically-wise,but at the time I was like 8-9 years old, and was mostly interested in starting doom 2

So that was how my father implemented users at the time.

What on earth are you on about? It genuinely seems like you're arguing that the only difference between the literal famine of the cultural revolution and modern China is... I dunno, attitude or something.

Something had to build all that infrastructure: the factories, generators, plumbing, aqueducts, cell towers, refineries... If you have an alternative economics that can get all that without "economic growth", then you really need to start explaining it to people.
I would agree that there exists a distinct and mostly disjoint set of people: flaggers vs debaters, to use the OP's terminology. I don't see that tension going away. It's certainly a long-standing tension online.

I disagree fairly comprehensively with everything after that first point, and I'll leave it at that to avoid the flamewar. :-)
OpenCL made the mistake of being C only in the beginning while CUDA embraced C, C++ and Fortran, plus any language that would bother to write a PTX backend.

Tourlane | Berlin, Germany | Frontend (React) Backend (Ruby/AWS/Go) | Full-time | Visa | Onsite

We screw up every week. Every week in a new way. Still, we get closer and closer to our goals. The company is about 90 employees, but the product team is about 30. We sell tours for different parts of the world and we creating a platform to scale that.

We have the typical perks: 1800eur edu budget + 2 days for conferences + the equipment you prefer.
As today we are 3 backend and 3 frontend. The frontend are working with next.js and react. The backend with AWS / Terraform / CircleCi / Ruby / Go.

One of the coolest thing we have, is that non tech people are sending us pull requests. That pull requests will generate a adhoc staging environment and domain (for the main frontend and backend app). Once the person doing the changes is happy, he/she will send us the pull request for review to some dev. After approve, they merge it to master and it goes to production.

If you are lazy person that likes automation,
If you think the most important thing is to add value to company,
and if you want to have autonomy within the team,

We want to create the best travel experience, and at this stage we need one more backend and one more frontend to help us.

I can't speak for the community, but I can speak for myself. I've always found the noise-to-value ratio way off. Blockchain is not a new idea, but it's gained popularity because of bitcoin, and if it didn't survive the 90s on its own merit then how much value is there, really?

I'm happy to be proven wrong, but I'm not going to be the one to going out of my way to prove it right.
I'm very confident in the future. What a time it is to be alive.
1. The vast majority of blockchain/ICO/cryptocurrency startups are buzzword abusing scams and schemes

2. Everyone else seems to want to use the blockchain for wildly inappropriate applications

3. There's a small subset of people who have realized and monetized that adding the word "blockchain" will result in more money magically appearing

4. There's a fair segment that just want to use cryptocurrency to commit illegal acts and evade taxes (we're going to use Monero to run prostitution rings!)

There are some people doing some genuinely awesome things in this space, but for every person using smart contracts for low-cost electricity arbitrage, there's a dozen other people using ICOs to create distributed-blockchains-over-bittorrent that will use "machine learning" and "AI" to solve the unsolvable.

Throwing buzzwords in the mix doesn't create solutions, it only attracts dumb investors.

Trends Piloting the Development of NextGen Infrastructures
Because like any trendy technology it was way oversold. We are mainly tech people here and when we look at the current state of the art, it's very easy to see the technical shortcomings (the state of the art is still pretty bad). What the blockchain critics on HN generally don't see is the future potential of the current (mostly half-backed) technologies.
I would imagine because of the amount of conflation that goes on with blockchain and cryptocurrencies and because of the amount of conflation that goes on with the use cases for blockchain and cryptocurrencies. From what I've seen locally, the number of people I've met at startup events/meetups/etc NYC starting a "blockchain" startup without being able to articulate the value prop of the use for a distributed ledger or equivalent implementation in their idea is mind boggling. Someone I know in the music industry told me just last week they're starting to "pivot their career into the blockchain industry".
And yet GM has an available EV car and Tesla does not.

And yet Tesla will not be able to deliver the cheap model 3 and GM has been doing it.

That's a substantial claim - without any evidence. No surprise though - it's easy to be pulled into the Musk hype.
My issue is that I don’t think I know of a news org that I trust to be both ethical and correct enough that their banner would matter enough for a significant video.

CBS and Dan Rather takes documents months before the 2004 election [0] and Rather still have 400k+ twitter followers. Even BBC didn’t cover the Iraq War properly when we really needed it to [1].

I read news for opinion and some awareness. But I’d trust a video of Trump strangling a hobo about the same from BBC as TMZ and would need a lot of verification.

Ask HN: Good Python Machine Learning Codebases to read?
Hi everyone! Looking for codebases in Python doing machine learning to follow the practice of reading high quality code as a way to improve (not looking for framework or library codebases but codebases that are trying to solve problems - e.g. recommendation system for movies, etc.)

Would be a bonus to have well structured and commented code (not new to programming or machine learning but looking to improve)

(Partially inspired by this thread - https://news.ycombinator.com/item?id=9896369)

Thanks!
Part of the problem, if not a large-ish part of the problem, is that apparently drugs and alcohol are usually restricted from homeless shelters.

And addiction is a large component of homelessness, but if you're still addicted you're obviously not going to spend much time in a place where you have to go cold turkey to enter.

So, my ( probably naive ) suggestion would be to allow drugs and alcohol in the shelters, hopefully giving the residents long enough of a chance to receive some help. No it's just a revolving door that doesn't appear to be helping anyone.

Universal basic income too. :-)
Completely agree. I generally take an awful lot of time completing a book. And it's not that I'm a very slow reader. It's just that when reading non fiction, I often Google something from the book, or think about something a bit more and sometimes just flip back to reread a few pages and improve my understanding.

This guy seems to veer out of the way of the natural conclusion near the end:

> The term “woman-child” lacks teeth, because damseling and self-infantilization are acceptable for women.

He seems to think that the fact that women are infantilized is a bonus, as if the 'pity points' accrued are the utility function of the game being played. This completely ignores the -actual advantages- that have been accruing for thousands of years from -massive, systemic violence-.

The author seems to have trouble realizing just how pervasive the misogyny goes. It's not some tit-for-tat twitter debate about who pays for dinner (this is what PUA forums try to pretend).

I have yet to come across any problems that are solved better with a blockchain than with any other traditional technology - except for the original one, a distributed electronic currency.

And I'm totally not against the concept. This is definitely a "prove me wrong" moment. It's just that I've been looking for a long time, and so far, nothing.
The OP's right though.

In my personal estimation? About two more Apple A-series generations. You can see from their focus on IPC over core count + speed (as other ARM manufacturers are) that they’re clearly tuning for desktop oriented workloads. With where the Bionic is compared to Intel’s mobile offerings, and the leaps they’re making it’s not too far off. And the only other manufacturers in their realm are Nvidia (with Denver/Denver2) and Cavium (ThunderX2).
Well, the amount of scammers and get rick quick merchants starting cryptocurrencies and blockchain based products has likely left a sour taste for many people here, especially when they hear about yet another million dollar ICO that seemingly came out of nowhere.

And it's also meant a lot of people who nothing about tech are starting businesses and projects revolving around blockchains and what not despite not have any real reason to use them or a need that said technology actually solves. So people here end up seeing these projects as the equivalent to 'Uber for dog walkers' or a 'distributed basket weaving platform'.

Oh, and maybe because the topic has been done to death already and people are getting sick of discussing it.
How would that compare to the top end Intel chips that Apple is using in the iMac Pro and the forthcoming Mac Pro?
