The article is a good read but I really hate the repeated assertions that clones are all part of the same single organism. That's just not true--that's not how "organism" is defined. The analogy they use to justify it, the ant colony, is just as inaccurate; each ant is an individual organism. Perhaps I'm being pedantic, but there's someone out there walking away from this article with a terrible misunderstanding of what an "organism" is. Science journalism should be about informing, not misinforming.
The Bootcamp Education Model Works.  Why
Reminds me of a story I remember hearing long ago about Tom Scholz of Boston trying to save their old tapes and how fragile they were.
the reason for that is it takes the whole team (server, host, line cooks, busser, etc) working in concert to give you good service (timely, tasty, well-prepared food in an enjoyable environment).
Show HN: PropertyWebBuilder – open source real estate site builder
A few months ago I asked for opinions here about if I should open source my code for creating real estate websites. The general consensus was that I should not but I decided to do it anyway ;)

Here is the code:

https://github.com/etewiah/property_web_builder

Will appreciate any feedback about how to make it more useful and developer friendly. Its gained a few github stars and a few people seem interested but I really want it to be used a lot more.

Does it have to be like this? Can't there be room for more than one kind of game? I don't think Code is saying that we need to get rid of one kind of game to make room for another kind of game. I think she's just saying that she wishes that there were some interesting games with depth that she could share with people other than white males. She says how much she likes games and what kind of experiences she got from them, but then she can't share those experiences with many close friends in her life.

Surely there's room for more than one kind of toy in the sandlot?

Ask HN: Gradle or Maven in 2017?
I am starting a new project using Spring Framework which is planned to last for a long time and am deciding on what to choose between Gradle and Maven. Last time I tried to use Gradle it was painfully slow getting dependencies so I reverted to Maven before the project got large. I see that they made some improvements with that regards but it still feels slower in a small test. Can somebody who is using Gradle now in a large project give some insight?

There are untold thousands of unlabelled canisters in film archives all around the world. Some of them are undoubtedly very important, but until they're catalogued we won't even know.

Unfortunately, most film archives are enormously under-funded. Here in the UK, arts funding (which is where this normally comes from) has dropped dramatically since the financial crisis. When Jeremy Hunt axed the UK Film Council[1], most regional film archives totally lost their funding. When their money disappeared, so did any chance of employing cataloguers.

A proper archive will at least be storing their film in environments with the proper humidity and temperature to reduce decomposition as much as possible.

The other side of it is that the more decomposition that's happened, the more time you need to invest into restoration. See the 11 year restoration of the 18 minute Voyage dans la Lune for an extreme example[2]. That kind of effort is only possible for a film of enormous historical importance and at least some commercial value.

"2.3" is a bit ambiguous as a label; do you mean part 3 of question 2, or the part of question 2 in which equation 2.3 occurs?

If you mean part 2 of question 2: my answer would be "dF/dx = del F/del y dy/dx + del F/del y' dy'/dx; but we know del F/del y = d/dx(del F/del y'), so dF/dx = d/dx(del F/del y') dy/dx + del F/del y' dy'/dx, which by the product rule is d/dx(y' del F/del y'). Now integrate both sides."

If you mean part 3 of question 2: just substitute F(y, y') from (2.2) into (2.4).
It's not "NOP" code because it has an observable side-effect, unfortunately: time passing. This can be trivially observed with another interval timer at smaller resolution than 500ms.

I have seen plenty of libraries using null to indicate an error. If this wasn't the case, as you allege, then why do Kotlin devs act like it's such a big deal? Why add a language feature for something that isn't even considered an issue instead of e.g. improving how Kotlin handles checked exceptions?
People frequently say "nobody" when they mean "almost nobody" and it doesn't lead anywhere productive to point out the odd counterexample.

Well, you also got to wage wars in various countries via drones and residual troop deployments and special operations. That takes up quite a bit.

Also, you got to enjoy having a basic pension after retirement, as well as free healthcare for the elderly and poor. Who wants to live in a country with a bunch of poor and old sick people who can't afford food and healthcare? That sounds depressing as hell.

> why is there no state where you can choose whom to give (at least part of) your taxes?

Many states have tax deductions on charitable donations. They're mostly used by wealthy people to shirk their taxes by "donating" to a "charity" that serves their own interests (e.g. "donating" a valuable painting to an "art museum" they establish next door to their house, open only by appointment with them).
Is it me, or does it piss anybody else off when stuff like this happens, especially with something of this magnitude?

I mean - as terrible and stupid as it still is - it is one thing to lose the original video footage of the first moon landing (GAH!).

But here we have data, about the most destructive weapons ever created, that just sits gathering dust, decomposing, becoming useless. Meanwhile, the computer models, being developed and designed by people who likely weren't even alive at the time of these tests, are relying on data and assumptions that don't match up with the data in those tests!

What does that mean? I don't know - but it doesn't sound good on the surface - not good at all. Would these weapons work if needed (let's hope that is never the case!)? Would they fail? Are they failing now?

And why wasn't this stuff digitized a long time ago? Why do we not seem to care about this crap?

Lastly - we are in an era that are so far away from that time period of testing. It bothers me and frightens me that so many people - most who either weren't alive at the time, or were children with no access - these people have no idea about the destructive power of these weapons, having not experienced first-hand the nuclear tests that did occur. These men and women who were "there" are dying or dead already. And those replacing them seem to be getting bolder about wanting to use these weapons, without having the gut affirmation of what they would unleash. I have an opinion - which may be unfounded and false - that one of things that have kept us (humanity) from nuclear annihilation thru war has been the fact that there are still people who remember those tests. Those who remember - at a gut level - that the power of these weapons, from witnessing (or having other close-knowledge of other witnesses) these tests - have stuck with them in a way that can only be akin to that of say, seeing the earth from the moon, or from space.

It's a primal thing - the knowledge from seeing these weapons and their capabilities - a single one which can destroy an entire city - and knowing we and "them" target many to many to cities and other places...

Yet - here we are, people wanting to use them. And the data that could help make these weapons "safer" rotting away. I'm not sure if that is a good or bad thing overall...

Fuck these weapons.

Why You Should Be Using Supported PHP Versions
I guess I see it as: People should be worrying. Things are scary, and there's more field of interest than ever to worry about. But people have to focus on what they think is the most important thing, or set of things, to worry about. I see news as a way to give them an introduction to the subject. Though, I agree it doesn't seem to work well in practice. I wonder what could change to make that happen.
Except for here in the states 25% of the taxpayer money is going to military, intelligence and debt from past wars we know to have been bad ideas and knew all along were bad ideas.

And let's just say another 25% is misspent. In a country this big and bloated, that's also likely a low ball figure. But overall, only 50% of taxpayer money is going to anything remotely properly executed and needed.

That said, our public schools suck, we invest nothing in research, we don't provide healthcare until your old, and our interstate highways were built 70 years ago, and state and local governments handle needed construction now, yet they take the smallest percentage of our taxes. Some states like Nevada don't even charge state income tax.

In my view I'd be way happier paying taxes if this was managed right. That means cut military spending by 90% knowing we are never going to need an aircraft carrier again while completely evacuating the Middle East, and the state local government's charge more since they will be more effective at putting it to use.

Taxes should be no more than 30% total (federal, state + local) like the Apple App Store.

Yea, likely not happening any time soon. But that's what is correct imho.
So your concern isn't just with anecdotes, but with observational data in general?

I agree that experimental data is preferred, but sometimes observational data is all we've got, right?
Except in most cases disruption doesn't work. The canonical examples from "The Innovator's Dilemma" all fall apart under scrutiny (as in the "disrupted" companies end up eating their disrupters for breakfast). GM is now doing a better job of executing in Tesla's space than Tesla, and that situation is not going to get better for Tesla.

It really goes beyond that. Th proverbial prints in the shoebox are subject to fire, flood, analog deteriorations, and just being lost in a move or when cleaning out the attic while digital can be backed up six ways from Sunday.

Of course, in practice how many people are one head crash away from losing most of their photos stored on a consumer-grade USB drive? And of course, many people are also subject to cloud companies going out of business, computer equipment being stolen, losing access to a site online, etc. And the situation with gaining access to photos and other things if a family member dies or whatever is another whole issue.
Are private charities more efficient with their defense spending?
Lol no! I always use 1x on podcasts. In this case specially because i am no native english speaker and the content is very dense (on the more interesting parts I would even rewind to listen twice). On top, I agree with the other comment that his storytelling skills are great and worth savoring.

But even on brazilian, humorous podcasts i dont speed up. I listen while doing chores and the ocasional commute. No hurry. I took about a month to finish this one.
The situation here is IMO similar to Mozilla vs XUL, except when they actually decided to drop it a ton of people decided to drop firefox. I'm talking about compatibility in general here, not js scrolling specifically.

I think such laws are wrong. Scraping is what Google and Web Archive does and it serves good purposes. For example, one can make an application that compares prices for the same item at different internet shops and helps to find the cheapest offer.

I don't understand what's wrong with downloading the information that is published on a public web server. That is what that server was made for in the first place.

Of course there are people who scrape the website, add advertisement and optimize it to rank better than the original website. But this problem can solved with other measures.

And of course those who do the scraping must limit their request rate so the server doesn't get overloaded.

> RGB and HSL are related, but I wouldn't say HSL is based on RGB.

HSL is explicitly defined as a transformation from RGB space, so each RGB triangle has a corresponding HSL space.

RGB is absolute garbage for doing anything other than displaying pixels. It's so bad, that the (piecewise) linear transformation to HSL is perceived by many to be good, when it's still equally terrible.

The main problem is that not all wavelengths of light contribute equally to perceived brightness in our color vision. Any color space that puts red, green, and blue on equal footing for a transformation is going to produce bad results. If you really want a linear transformation from RGB, you'll want to use something like luma instead (Y = .21R + .72G + .07B, according to Wikipedia)--you'll go from bad to acceptable, as luma is only a few percent off from the accurate results.

If you want to do color interpolation, you'll absolutely want to use CIELAB, which was explicitly designed for this purpose. Any good toolkit should provide CIELAB--d3 does, for example. If not, it's not hard to find snippets to do the conversion for you on places like stack overflow.

That seems reasonable. I just seen one video in particular where they made it seem like it's impossible not to scratch the screen on the recharging station, and very easy to put the handles on incorrectly and have them stuck, also dead pixels and the game just bugging out completely. I have no plans to buy one, as it's just not my cup of tea, but very interested to hear if this was actually common.
At the beginning they talk about places that have lost income, but the internet has also preserved a lot of content that was only accessible if you visited a place that owned a copy (library, museum, etc).

For instance, UCLA has a great old lecture series from the '60s they've been digitizing:
https://www.findlectures.com/?p=1&collection1=UCLA%20Archive...

There are a ton of other places doing this. Once these types of projects are funded once, they can be available pretty much forever, because they are drop in the bucket for youtube, which seems tremendously cost effective.

Dan Carlin is excellent. Both his Hardcore History and Common Sense podcasts are always insightful. He's a great model of a practical skeptic - he's always skeptical, but he allows himself to think through both the skeptical and non-skeptical interpretation of a piece of information without giving preference to one or another based on his personal biases.
They said it 'could be gone within 10 years' 14 years ago, and (I'm not an economist, I could be thinking of this wrong) yet bananas are cheaper than ever before when accounting for inflation.

I don't know about other countries, but here in the UK, most universities don't require an entrance exam to study computer science (they go by the grades you leave secondary school / sixth form with).

Cheating is such a fluid concept anyway, and it's inconsistently applied. The Tour de France will kick you out for riding a motorbike; MotoGP forces you to ride a motorbike.

The rules are there to provide some semblance of a level playing field and to ensure that the relevant skills are being assessed. An elementary school arithmetic test is a pointless exercise if calculators are allowed; an undergraduate engineering test would be a farce if calculators weren't allowed.

Also, running old games in DOS Box is often a finicky process that requires some tinkering for every game. That's one of the reasons GOG.com took off so rapidly. People are gladly paying several bucks to save themselves the trouble of messing with configs and reading forums about game's quirks.

This isn't a huge deterrent in case of games, but it will be a huge deterrent for retro-browsing, because the whole point to the Web is its interconnectedness. Plus, there are many more websites than there are games.

Your basic argument is the naturalistic fallacy, that "nature" "chooses" more optimally than directed engineering can.

I wouldn't disagree that genetic diversity in plants and animals increase the speed of survival and adaptability probabilities in aggregate. That is however a significantly different argument than the goal of optimization which is what parents are doing when they eg. select for an embryo without BRCA-1.

I pay my taxes in order to avoid being a victim of state violence, but when I do, I say a prayer for the victims of my failure to be strong enough to do the right thing, which is to deprive the state of the means to do evil.
