Ask HN: What is the best way to learn how to design experiments?
I don't have a background in science, math, or statistics.

I'd like to learn how to create experiments to test ideas in my business like doing x leads to y increase in sales.

Does anyone have books or resources that they could recommend on how to design business experiments that have good logic and are as data-backed as academic research? There are a lot of variables in my business so I'd like to avoid confusing correlation with causation, learn how to create a proper control group, and more.

For more context, I'm starting to get into machine learning and deep learning through fast.ai. What should I learn or be aware of as I move forward that is complementary or essential to machine learning?
Mel Gibson cheated on his wife. Still pretty Catholic!
Right, but that's not the point. I am referring the sushi standard defined in the article based on the cube illustration. In reality there is sushi that conforms to nearly all of those designations. Furthermore, tacos are filled, not wrapped.
Using my rule of thumb above: if I asked the waiter for a grilled cheese, but I didn't care what kind, I expect the waiter would be somewhat perplexed by this, since "grilled cheese" is a sufficient descriptor that there's basically one sandwich that satisfies the description.

If I asked for a melt but didn't care what kind, then I feel like the possibilities expand, and would include a regular grilled cheese.
Since you've put a lot more thought into classifying food than I have, perhaps you can answer this question:

Breakfast cereal: Soup, or not?
... so what? most code's hot and should be issued from the uop cache at 6uop/cl with "80%+ hit rate" from your source

you're really not making the case that "decode" is the bottleneck, are you unaware of the mitigations that x86 designs have taken to alleviate that? or are those mitigations your proof that the ISA's deficient
AFAIK, supposedly TMSC 7nm and Intel 10nm are about equivalent, but with 10nm being in a limbo, TMSC is ahead now.
> No, it's fundamentally a wayland issue.

It's not an "issue". It's a design decision.

As another example, Linux doesn't have just one desktop environment, like Windows or MacOS, would you say that's an "issue", even if it's a deliberate decision?
Von Braun was also the recipient of big time image rehabilitation courtesy the US, in exchange for his work after scooping them up in Operation Paperclip. Not to take anything away from his instrumental role in US rocket development, but I'd take any quotes and motivations with a grain of salt.

Some of the post's salad examples (spaghetti, poutine) could be interpreted as starch surrounded by non-starch. Thus I believe the rule would still consider turkey with stuffing to be a salad.
You misunderstand. Command line 'whois' is how you search for a domain initially. If it is available, the price is the standard price for a domain in that TLD. If it's already owned, you learn that also. Then you can visit www or visit the registrar to see if it is for sale and for how much.

You can also search on domains.google.com. They are known to not engage in these practices.

Picbreeder: Evolving Pictures Collaboratively Online (2008) [pdf]
Hey gang,

I'm one of the founders of Kosmos School and I'm super excited that we finished teaching our first class in VR. It's called Intro to Rockets and the students learned all about rockets in a very hands-on manner. We founded this company because we think that VR will change education fundamentally, and after building and teaching for the first time now we're even more convinced that VR is 10x better than doing this through Skype call or mobile/desktop app.

We're running our second and third classes in January. They're designed for teenagers (12-16 old) - if you're interested, you can enroll on our website: https://kosmosschool.com/

Let me know if you have any questions.

The water is recycled...due to the nature of the water in the Central Valley and its intended use, they can't just pump up the water from the ground all the time. The water needs to be treated to remove contaminants, then is constantly recycled to prevent algae growth.

The pool does use a ton of water when it gets (re)filled, but that's only a few times a year. Filling the entire pool uses about the same amount of water as the average California golf course uses in one day...

It’s also just localism all over again, except now it’s just straight up money that keep you out of the club instead of a more abstract idea of being a local.

The Surf Ranch is a high-end/test pool, and they've been pretty open about that.

For point of comparison, while 300,000 gallons sounds like a lot, a "storm" in LA can drop 100 million of gallons of rainwater in 24 hours...LA's catchbasin system absorbed 22 billion gallons of water in the 4 month period between October 2016 and Jan 2017 (https://www.scpr.org/news/2017/01/23/68360/how-much-storm-wa...)

It could be done entirely without external requests: the browser would be an amp interpreter, no need for the amp js as all.

If I went to a restaurant and ordered soup (surprise me!) and they gave me a bowl of cereal, I would likely have my goons come back and torch the place.

I mean, if they gave me gazpacho or a cold melon soup I also would not be thrilled, but I would not accuse them of violating the conditions that I had laid out.
Yes, from 2016 and using a definition of Millenials that went through 1998, so that “Millenials” was the age group including 18 year olds. (Which, if you click through to the cited source, you'll find out that the source has been revised to change.)

This is just restating the long established trend, true across generations, that the youngest-voting age group turns out at the lowest rates (it would be interesting, perhaps, to compare Millenials against other generations voting patterns at the same age to separate out generational from age trends, but this is just misattributing a consistent age trend to the generation that happens to be in an age category at the time of the analysis.)
I am a scientist, and any experiment that demonstrates a hypothesis I do not like is an experiment I do not accept.
>The other aspect is that while these skills are valuable for creating a "job" they do not have potential for creating "massive wealth". Why learn about storage if you aren't going to be part of the first 10 employees at a company that has a $10B exit? Let Amazon and the other cloud vendors worry about that stuff.

That seems like a completely ridiculous way to try to organize your life. Almost no companies have $10B exits.

It's just my opinion. If you feel this helps buy it. For me how you layout simple geometry and text is a trivial problem.

I get what this picture is trying to do, I get it's aesthetic. But I also know that almost ZERO effort was spent making it. Many "designs" have a less obvious aspect of this issue and I believe that this book is just dealing with issues that are more or less obvious.

Produck: Simple and Powerful Project Management Software
(generalized) predication is not a thing in ARM64. Is Apple cpu 7 wide even in 32 bit mode?

It is true though, as chroma pointed out, that intel can't decode load-op as full width.
Thanks for sharing! I do agree that's an awesome idea. I wonder why this isn't more popular. It made me think of flatland skim: https://www.youtube.com/watch?v=7UpWbILAIec
Exactly this. I run at 1920x1080 effective resolution on my 15" rMBP, and 1680x945 on my 13". I see the issue on both.

When I switch to the "default" scaling (1440x900 and 1280x800, respectively), it stops. Only the 15" has a discrete GPU, eliminating that as potentially causal.

The "problem" scaling is 1.5x. The default is 2x.

I have to pretty much reject this post wholesale. True the post it's disagreeing with picked weak examples. But other than that pretty much all of its overall points were actually very accurate.

The original article was not about json/scala/etc. It was about this:

To summarize, we have to deal with a lot of accidental complexity these days, for multiple reasons. First of all, we adopt techniques and abstractions without analying and evaluating their costs and their usefulness in our specific situation. Moreover, we love solving technological problems.

Produck is simple, beautiful, and powerful project management software for product teams. Some key features:

- Inline rich text editor for task descriptions
- Status, Priority, Multiple Assignees, and more
- List and Kanban board views
- Group issues by Assignee, Status, Priority, Type, Labels...
- Burndown & Sprint Reports
- Project & Sprint Overview

We started Produck with the vision of creating project management software that offers everything you need as a product team, wrapped in a beautiful and delightful experience. We’ve always loved the simplicity of Asana and the powerful features Jira offers, but we felt there was something missing in the middle: a tool that has the power product teams need and the simplicity everyone enjoys.

We are just getting started! We are on a mission to make everyone more efficient, and with that in mind we have a lot of great features in the works: inbox, workflow builder, more integrations, multi-language, Gantt, and AI to help you out.

I appreciate your time trying Produck and I would love your feedback!

I surfed in the UK all my life and loved every minute of it. Then, on a whim, my brother and I went travelling around the world surfing.

It after a while it struck us, "Oh, that's how you get good at surfing. Good, consistent waves." We came back a hundred times better at surfing, but it ruined UK waves for us. Waiting six months for a good day wasn't much fun.

We turned to kitesurfing.

I would love to have one of these wave parks near us, it would be so much fun to play around in.

Even if you take grilled cheese narrowly enough that it must have nothing but cheese between the bread, there are a fairly wide array of potential breads and potential cheeses and combinations of cheeses that there is definitely more than one sandwich that fits the description, even before considering that, in use, “grilled cheese” allows for additional ingredients.

FreeBSD is an entire operating system. Linux is just a kernel used in hundreds of different distros. It is correct that they are both UNIX like derivatives. FreeBSD is based on the BSD license, Linux on the GPL (this is important if you want to make something proprietary, like the PS4).

Most major Linux distros have different package managers and you download binary updates. They supply their own kernel with backports and custom compiled to stay in sync with the rest of their userland. In FreeBSD the kernel and userland are in sync so you dont have this issue.

Linux has better driver support due to more exposure to hardware.

You can go one for quite a while about how different they are, so they are very different. But you are right it is user preference.

So what these hoarders are doing is stealing the scooters -- rather than checking them out through the charger app, they're just grabbing them and tossing them in their van, and then keeping them in their home, where other chargers will fail to find them, thus increasing their bounty, until they "discover" the scooters, claim them through the app, charge them, and return them to their nest.

What if the bounty was influenced by the duty cycle of the scooters? So the more utilized the scooters are, the higher the bounty? What I'm wondering is if there is a way to shape the hoarder's behavior into something beneficial to the user base.

Somewhat related to California Water: There’s a documentary about California water use in Central Valley by land owners used for pistachios, pomegranates, etc. being crowdfunded right now: https://www.kickstarter.com/projects/7331688/pistachio-wars-...

The story originated in the 2013 essay “journey through oligarch valley”: https://www.nsfwcorp.com/dispatch/oligarch-valley/
"I don't think that a country like Cuba makes for a good data point on anything except embargoes."

Neither is Norway a good data point from which we can extrapolate the viability of Communism. Norway has a population of 5.5 million - smaller than the San Francisco Bay Area. It's also swimming in oil money.

It's probably easier to motivate people to work for the benefit of the whole community if the community is defined as a small number of people with whom you share a culture and background and live close to you.

Maybe that's why communism works occasionally on communes, but anything more expansive requires the brutal application of force to keep people in line.

how many amazon customers have they migrated to their existing ARM solutions?

like that's the bit that's missing, the servers sitting on a rack are meaningless without ARM customers, and amazon chips not existing didn't somehow prevent the demand. they sell arm compute now and it's a paltry fraction of the whole. pretending it's about TSMC scaling is ridiculous.

I'm not sure if the dates line up with your story.

Tetris Guidelines started with Tetris Worlds (2001). While the parent article makes numerous references to 2003 or later (the code says 2007, some various Perl bits are 2005, etc. etc.)

Fortunately, the article is never wrong per se. It is clearly written that "Standard Tetris" is the name that the article gives to the IBM PC version of Tetris (1986). Its just odd to me that it has references to all sorts of 2003, 2005, and 2007 stuff without mentioning SRS or Guidelines.

> Man, has any game been implemented more times than Tetris?

Yes, because it's a relatively complex game. My bet's on something much simpler like Rock–paper–scissors which has over 60 implementations just on Rosetta Code: https://rosettacode.org/wiki/Rock-paper-scissors

The "Number reversal game" has more implementations, but that's probably less unambiguously a game and more a special-case of of a programming problem: https://rosettacode.org/wiki/Number_reversal_game

This is not some random benchmarks. Both of these problems are things that I regularly encounter on actual websites. And it's great that FF styles it, but I'd rather have performance than system appropriate dropdowns.
It's pretty puzzling that somehow this repo became polarizing. It seems entirely harmless and silly.
No I didn't. You are saying the same thing as I did but if it's a TLD where you don't know a ballpark figure you'll have to look it up somewhere to see the price which is some registrar like GoDaddy for a lot of people (especially those that don't know much about what's going on in the background).

Availability is not the only factor that people look at when they first decide on a domain. Especially if it's a side project / startup and not a bigger project where it doesn't matter if it's 9.99 / year or 500 / year.
Is there no benchmark that measures the EPYC and Xeon chips on "large, branchy, pointer-chasing codes that everyone runs in production"? From everything I've seen, the Zen architecture is a win across the board.
