I usually find a lot to agree with in your posts, but this time I want to push back on arranged marriage = forced marriage. That's just false.

For the record, I upvoted the other comment that made this same point (as well as your comment). I considered thanking them, but long history suggests such comments by me go weird and problematic places. I don't know a fix for that, so I sometimes upvote as my only expression of gratitude for a good contribution to the discussion.

Many cultures have extended family, grandparents, other wives, other adults/older children do child care.

In my eyes, that is completely different from just hiring help.

FWIW, when my brother got custody of his infant son during his divorce, my father officially retired and stayed home with the child while my brother and mother continued working. My father never changed a single diaper for any of his own kids. I think he was in his 60s when he learned to change a diaper so he could provide childcare for his grandchild.

I have my reservations about the two career couple model that is promoted by so many people. It is promoted as a women's equality thing, but the reality is that those children are typically being raised by a woman, just not their own mother. It actually creates a class divide if you really think about it.

I don't know the solution, but we need to spend more time figuring out how to resolve this conflict without shortchanging some demographic. I don't see that issue being discussed enough.

Thank you for your comment. I think you misread part of mine, but if others also misread it, it's good to get that information out there.

Best.
Which part of the ip is hard to decode? If you don't like how a country's laws are shaped, then stop selling there. You can't have your pie and eat it too. Either you obey the market laws and sell or you don't. If someone is using a VPN to get around your geo ban, then I think that's the user's implicit choice.
‘Maya method’ is just clickbait. This is how most of the rest of the world operates. Kids being the boss is a relatively new phenomenon and probably started and flourished in the western/urban setting. I used to help with household chores until I went to college and all of that came in handy when I started to live on my own when I got my first job. And my mom mostly never asked me to do it, it was just about being part of the household and sharing responsibilities. And yes, I was never paid to do any of it, neither was my mom.

When telling someone that something they said was racist, it's important to keep it focused not on the person but the act. Racism and prejudice is learned, and it can certainly be unlearned. Unfortunately, you cannot unlearn mental illness.

Terry definitely was an old-school hacker that didn't care about whether or not his products saw mass adoption, he did it because it was what he wanted to do most. There is a lot of humor in TempleOS and Terry in his more reasonable moments was actually a very nice and caring person. I spent some time trying to convince HN to look past his troubles but alas it did not come to pass.

Auto makers very much care about resale value since it is pretty much the entire basis upon which a lease is priced, which is a huge deal considering ~30% of new cars are leased.

Furthermore, almost 80% of electric cars are leased [1]. When electric cars aren't being made for compliance reasons, or to lower the overall emissions of an auto maker's fleet (and thus subsidized in some way), then resale value will be of critical importance.

When I was learning Rails on a windows laptop I was running in to all sorts of problems and issues when following tutorials. Something wouldn't work and you would go off in to a two hour rabbit hole googling around trying to find the solution. Eventually I would get it working on windows. Most tutorials are for the mac but I would be following them on windows. One night I ran into another issue following a tutorial and I decided I was going to try to same tutorial on my wife's macbook. Tutorial went super smooth and I completed it in less time than I had been spending trying to trouble shoot each issue that came up doing the same thing on windows.

OSX just works. It will save you enough time to pay for the hardware and give you piece of mind make your life way easier.

Sure you could develop on windows but OSX is way easier at least in my experience (Rails and Laravel Development).

A macbook air is more than powerful enough for web development and you can get them on sale for less than the price of an upper end windows laptop.
Can someone explain whether "Diluted EPS" / Diluted Earnings Per Share is significant in valuing a stock, and also how that number is calculated and used in investing?

Amazon's #s in this regard are over 2X Apple's but there is a %age that is showing 1167% for Amazon vs 40.12% for Apple. What does this mean?

Amazon Diluted EPS	5.07	1167.5%
Apple Diluted EPS	2.34	40.12%
>Secondly, monetizing the EU is a step that usually occurs very late into the life of a startup. Startups almost always monetize the US first.

It's not a matter of what the founder/CEO of a startup chooses here. I will often open links from e.g. New York Times or other US news sites because something happened in New York or there's an interesting opinion piece that I want to read. These sites are profiting from my clicks so they have to obey the EU laws. If it was impossible for them to determine that I'm an EU citizen then it's a different story but an geo ban is trivial.
It ran into IRBs. It'll start in 2019. Maybe. See https://www.wired.com/story/y-combinator-learns-basic-income... (Yes, that's right, in 2018, you literally can't give away money without a ton of work.)
Right. The logical thing to do is to price it up as a lease without option to purchase / long-term hire contract and compare that to other competitors.

> Just wait until it really sinks in for their dealers that selling electric cars means greatly reduced maintenance.

How true is that? Batteries are expensive and wear out faster than engines. Even in conventional cars, some of my more expensive repairs have been electronics. And it's not like an electric car doesn't have a hundred mechanicl parts that wear out just as fast as a conventional car.

I could see a specific brand or model being very reliable, but I'm skeptical electric cars will make extensive car maintenance far less common than it is now (especially anywhere that doesn't require emissions testing).

I have absolutely no interest in TempleOS as a codebase, and I can't imagine that many people would ever want to use it as their main OS. However, Terry Davis and TempleOS expanded my conception of the possibilities of computing. Alan Perlis said, "A language that doesn't affect the way you think about programming, is not worth knowing," and by that standard, I think that Terry and TempleOS have secured an eternal legacy.
If anyone reads this and is curious about market share like I was, here's some (imperfect) data: https://insights.stackoverflow.com/survey/2018/#technology-d...

Windows is 50%. Mac and Linux each have about 25%.

That makes OS X about 2x more popular with devs than desktops as a whole.
It's a pity we never could be inclusive enough to take someone in who clearly needed a bit of support. Terry definitely was a troubled person, there is zero doubt about that but if you looked past the sillyness (which I understand is hard in an environment that puts great value on political correctness) he was a really nice guy with some surprising quirks and a good sense of humor. On off days he was not so nice. Nobody's perfect.
Your thought is in line with traditional thinking, but
a 2015 study in the Wilderness & Emergency Medicine Journal found that cold packs applied to capillary-dense surfaces (cheeks, palms, soles) caused a greater reduction in body temperature that the traditional core/artery surfaces (groin, armpits, neck).

Thanks man, it really sucks that this is what HN has become. IMO its a sign of the times w/ Trump etc... You literally get down voted and flagged for refusing to ignore racism and praise a racist. The worst part is that they don't even see it.
And sometimes it’s a misguided attempt at shock humor. And sometimes it’s self-sabotage. We don’t know what he really believed or wanted to achieve. The one thing we do know is he was sick. No sensible person will take the rantings of an obviously sick person and think racism is ok.
Terry came to an event I helped host many years ago and showed off his baffling inventions. We felt a bit bad because it was really intended to be just a party, but he'd made a huge effort to come and so we set up and area and let him demo.

It was the kind of crazy that I'm sure resembled Tesla's less-good ideas, but everyone there was in agreement that while we didn't plan to switch, what he showed was truly original.

Like many of you, this story makes me really sad. I struggle with mental illness, but not like Terry did. It had to have been hard - not a strong enough word - and I never feel like we're doing enough to help.

All I can do, at this point, is stand and be counted.

There are some calculators that help you figure this out. Here's one I just found with a Google search: https://www.optimizely.com/sample-size-calculator/

The idea is that to get results, you need some combination of a lot of data, or a big impact from the changes your testing. If you just change the color of the signup button, it probably won't have a major impact on the conversion rate, so you'll need a lot more data to reach a conclusion. But if you test a completely new landing page, it might have a better chance of being meaningfully different (better or worse, who knows until you test?) and so you wouldn't need as many visitors to get a result.

My solution was designed for a very narrow use case where there is one user and multiple devices. The main reason I designed it because I did not want to stand up a cloud service for storing user info. I wanted to offload that responsibility to a file sharing system like Dropbox or OneDrive. It's not meant for anything beyond a very simple use case.
Interesting.

Just no, and I don't understand what's the point in posting uneducated personal opinions here and stating them as facts.

The "European dark ages" had literally zero progress in algebra, it was Boethius's De arithmetica in the Quadrivium for six centuries until Fibonacci's Liber abaci introduced the hindu-arabic numbers, which he learned in what today we call Algeria. And then algebraic methods (BTW "algorithm" comes from the name of al-Khwarizmi, "algebra" comes from "al-jabr") were unknown in Europe until Robert of Chester translated Khwarizmi's "Hisab Al-jabr w'al-muqabala" to Latin from the original in Arabic. There was zero progress in algebra in Europe for six centuries because they had no algebra. After that (there was a bit of a divide between abacists and algebrists), people doing algebra in Europe used that book until the printed arithmetics/algebras of the 16th century. All of them do mention their sources: you can download them in google books and look it up.
If you have an easy way of rolling out tests, and enough data to reach statistical significance, IMHO it's never too early to test.
Costs. It answers the question “How much does it cost to run a startup?”. Popular SaaS companies often talk about their MRR, but what about their monthly running costs?

Currently building the list of more open startups, but some interesting ones:

Blurt, recently launched writing/focus tool at $31.67 using DigitalOcean and Github;
GoRails, 4 years old Ruby on Rails learning at $506, amongst others Wistia, Podia, Amazon S3,
Krit, agency, amongst others, uses: CircleCI, Github, Heroku and Surge.
Feel free to add your startup / side-project. Interested in hearing your thoughts.

How can they be orthogonal when eventually you need open software of some kind to make a verification?

If the software I use to verify the closed source software is closed, then I will need another piece of software to verify that the verify-ing software is what it says it is and so on until we reach a piece of software that I can verify with my own eyes (or a friend has verified with their eyes).

We all eventually have to place our trust somewhere but we shouldn't have to agree with where you decided to trust.
Why isn't functionality like this in Google Scholar yet?
I hope so. I'm a little worried it'll only ever be appreciated in niche communities that really understand the depth of what he did. Maybe I'm not giving enough credit to fringe artists, but I don't know that it'd be easy to express how impressive it is to build a functional OS as a single person that could do as much as his did, with the hardware it was based on.
No one scrolls to the end of a long form article to get a recipe. Instead, they just close the tab and say "too long; didn't read."

In order to be useful, you probably want to see AB tests reaching a conclusion in under 30 days. I'd say for a conversion rate goal, this is going to be when you have around 100k visitors a month.

There are a few variables to consider

- What goal would you like to AB test? Conversion rate is an end-of-funnel goal that needs a lot of traffic, you can use upper funnel goals like product views, add to bag etc to get quicker conclusions (not as accurate but often a good approximation)

- The stats engine/AB testing tool you are using. More simple tools might conclude quicker but in my experience they can be so inaccurate they are counter productive. Usually a long time to conclude = reliable results. I've never used Google Optimize so I'm not sure where it stands.

- How many people are being exposed to the AB test, for example is it all web traffic or just mobile?

- How much of an affect the AB test has on behavior. A button color/text change will normally take long to conclude than a feature that's really helping your users.

- How confident do you want to be before reaching a conclusion? I'd recommend looking for 95% confidence in uplift before concluding an AB test.

I had Hughes as a lecturer in University (Chalmers, Sweden) and we heavily utilized quick check in our Haskell courses. He’s a great lecturer and a brilliant mind, I do think they still teach new CS students Haskell with QuickCheck as a first course.
Seriously, +1 to this. Defining key metrics is something where you should sit down with a data scientist that is familiar with your domain. In my experience, the problem isn't that people can't A/B test, they don't know what to test or how to determine if an experiment was "successful".
VSTS being down all day has had a non-negligible impact for us. We have most of our deployment pipelines there, and they've been inaccessible all day.
Terry was schizophrenic and was homeless and in poverty due to his condition. Tragically, he is basically the proverbial homeless person you see on the street. Outside of UBI it is very hard to help these people.

The sad fact is that it's very hard to take care of and control people like Terry due to their illness. They have delusions and think you are out to get them.

If you look at the criteria for schizophrenia it becomes a bit more clear: https://www.webmd.com/schizophrenia/schizophrenia-tests
Mostly, it was probably climate: the last (current) Ice Age, the "Quaternary glaciation" took a breather about 15kya. Things warmed nicely for about two millennia, then the Younger Dryas, a cold spell of about a millennium, ended about 11-12 kya. Before this, the "Last Glacial Maximum" (just what it sounds like) was glacier city. Ice was maxed ~26,500 years ago, ending 16-13kya, depending on whom you talk to. Even far from the ice, the climate was radically different from today.

Along with the serious climate swings, our culture changed. How much is straight-up the result of less ice is debatable, (I don't want to sound like Jared Diamond), but the fact remains: glaciers went, we developed agriculture. And we've been on the treadmill ever since.

Some pretty easy rules of thumb, assuming you have a decent grasp on your economics. Look at it as a "low hanging fruit" optimization problem -- do you put resources into running a test (+ opportunity cost for lost sales), or into something else?

Suppose you have 10k monthly sessions with a 0.5% conversion rate (50 conversions). How many more customers would you need in order to prioritize running a test? If 55 conversions in a given month means you crush important KPIs, then that's probably worth testing -- you just need a 10% lift.*

Also keep in mind that running A/B tests (1 control, 1 treatment) is suboptimal. That tests, "does this beat what I have now?" The more important question is "what is my best option?".

OTOH, if other things like messaging and product are stable, you can test a smaller traffic site by leaving it running longer.

My rough estimate is 100 conversion events in the time the test runs. So if I have 100 conversion events in 1 month, it may make sense to run a 2-3 option + 1 control test for 1 month.

(You can also test much larger things than buttons. For startups, I like to suggest trying out positioning or value statements and seeing how visitors respond!)

* however, it'll take a long time for you to reach statistical confidence for a 10% lift in rate, with only 50 conversion events across all tests.

Not yet, but I'll definitely have a look. Thanks!
The last heavily traffic site I worked on wouldn't perform an A/B test unless they could experiment with tens of thousands of daily active users. The experiments would last 2-3 weeks to gain statistical significance. A page usually had a 70/30 control experiment split.

The challenge is gaining statistically significant data. I think it is easier for an early stage customer to talk to their customers versus go through the time of a split test.
I use OneNote - it's really great. Until it suddenly decides it doesn't want to sync anymore.
Google Optimize offers MAB testing, which is awesome. Personally, I don't see it as a "when do results become reliable" problem -- it's a "what is the cost of a false positive, false negative, or 'do nothing' decision?"
Not just smaller dealerships - other manufacturers. If an area only has Ford dealerships in it (because Ford bought them all), they would then have a monopoly over car sales and maintenance in that area. If the area's big enough that people wouldn't be expected to travel much further to make a purchase or look for after-sales service, this would have meant a significant reduction in competition.
R's functionality for cleaning, reshaping, and otherwise manipulating data is also far ahead of all other languages I've tried, including Python. (As far as I'm aware, Python's current data manipulation functionality is pretty much in line with the 8-year-old R packages reshape2, which is officially retired, and plyr, which has mostly been supplanted by newer packages.)
I can believe that's true for lowering core body temperature due to the larger surface area of capillary blood, but the post I was replying to said that cooling the head is specifically supposed to target just the brain and not the rest of the body:

Cold towels on the head is to lower brain temperature while allowing the fever to run elsewhere

It still seems that if the goal is to cool the brain and not the entire body, cooling the blood on its way to the brain is better than surface cooling blood in the scalp that's going to soon leave the head through veins.
