I think it's odd that anyone would bother to complain about such a thing. I think it would annoying if they redid the layout of the store. Just putting toys under one general category just seems like the least concerning matter in the world.
I may be stepping on a landmine, but your numbers make me curious. Is the goal of gender diversity 50/50 female/male, or is it 20/80 female/male based off the compsci graduates? What does it mean to have a diverse development team, and how did those numbers happen?

Isn't the United States in practice a worst of both worlds approach where you have both imperial and metric measurements inconsistently mixed together?
>If someone finds a way to produce addictive drugs from yeast then a whole new ball park could be opened up in the war on drugs.

More like a whole new ballpark in the devastation of human rights. How exactly do you fight against this without a totalitarian police state? The gene labs could be anywhere in the world, bringing a new strain in would be as simple as tiny sealed pocket in just about anything you could imagine. Would the yeast itself be considered illegal? How much would be, a few micrograms?

And this is just the early days of gene manipulation. Way better and more potent combinations will be made at some point, because even though it may be 'somewhat' difficult, there is a lot of money to be made. Which turns back to the government now monitoring everybody that has knowledge and ability in the genetics world since they could be a drug manufacture.

Future will be an interesting place.
> In Rust, if you need shared ownership, but you're not doing anything with threads, you can remove that overhead.

If I am following you well, then what you are saying is that you if you are in a single thread application you don't need to use a shared_ptr equivalent. Wouldn't that mean that you are using a garbage collected pointer? (Which should have a greater overhead than a shared pointer) because otherwise you would be using plain old raw pointers (with all its problems).

> but no one is bitching about the fact we have very very very few men working in the child care industry, for instance

Don't lie. A simple websearch returns very many hits for people talking about the shortage of men in pre-school and primary school education.
Of course it's going to be hard. Changing legacy code always is. But this kind of argument seems to be presented in the US for everything from gay marriages to gun control laws.

If you really want to, you can do it. And it's not as painful as presented especially since many countries have done it (https://en.wikipedia.org/wiki/Metric_system). And the longer you wait the more painful it becomes.

Or to 'entertain'/'occupy' the still operational brain-cells during the flushing period (like tv shows and movies during long flights or dialysis).
>That we all have the same access to opportunity, encouragement, resources, etc.

Taking this to its logical conclusion then. Are you saying that "What have you done, and what are you working on?" is sexist because focusing on if people are working on something useful is sexist? If so, you are implying that women are not as useful, which sort of contradicts the idea that women are being underpaid for doing the same work.

So which is it? Is it that women are underprivileged and therefore producing less output, or should they be paid equally because they are doing the same?

The Pentagon's 'Concurrency Myth' Is Now Available in Supercarrier Size
The current title is misleading, and should be rephrased as "Russian antivirus firm accused of faking malware to harm rivals" (or, better yet, "Kaspersky accused of faking malware to harm rivals"). There's absolutely zero actual evidence or examples in the article of Kaspersky doing anything, and the article title in its current form reeks of sensationalism and click-baitiness.

Perhaps a mod should step in and cleanup the title a bit? I realize it's technically the original, but it's still misleading.
Well, of course none of these things are all particularly noteworthy in isolation. But it takes someone to put them all together into a working PoC.

On the Javascript part, they might very well be able to port this. Since any modern browser now JITs Javascript, it just becomes a matter of sculpting the JS to get the desired native code from the JIT.

I found this an extremely helpful comment! Thanks very much, chenglou!

EDIT: Though, I personally think it actually would be pretty helpful if ImmutableJS put something like this in their docs: "it's linear theoretically but most of the time it's really almost constant time"
Hydroponic farms, vertical farms, and agroecology could all do even better. Unsustainable food production is more of a contributor than personal consumption (though people's obsession with meaningless green lawns is also ridiculous).

I wish the article did a better job of exploring various agricultural solutions - drip irrigation is just a baby step when compared to something like hydroponics. Hydroponic production uses anywhere (and I'm just trying to remember the various claims I've seen in both studies and articles without going back to them) from 75%-90% less water than conventional ag, beating drip irrigation off the low end.

Agroecology challenges the monoculture system that (I think) caused this over-consumption. By planting thirsty crops like corn and polluting the existing aquacultures with the pesticides needed to preserve an area lacking any sort of biodiversity, monocultures have created a fragile food supply that increasing prices (and terrible subsidies) continue to highlight. Agroecology, on the other hand, encourages a system of farming that takes into account the cultural/social context of a region while suggesting methods (grounding those suggestions in data) of production that respect local ecology and agricultural practices for increased production.
What's the total cost of not switching? I'm willing to bet it's in the tens of billions each year.

All your major trade partners use the metric system: EU, China, India, Australia.
I haven't read through SG14, but I'm wondering why the fixed point implementation doesn't provide bases other than binary. Fixed point math has uses well beyond game development, and honestly too many people just use floating point by default.

For example, a decimal base is useful for representing prices that are otherwise unrepresentable in binary (e.g. a penny).
Everything's fine, everything said so far here it's fine. But I was around here when that happened, which was not that much time ago so I find it weird that you guys don't remember.

Twitter pulled some very dirty stuff on Meerkat, merely days before launching Periscope and later, in order to favour their own Meerkat clone. That's when everything changed from 'it's a free market' to 'it's our market and we can kick you out for no reason'. And yeah, it actually is Twitter's market, they are allowed to do anything they like with it and "monopoly regulations" aside, they can kick you out of their for no reason.

But let me tell you what I don't find ethical about all of this. That when you are going to develop for them, they do not tell you straight away: we are going to fuck you up if what you do turns out to be valuable; quite the contrary, they just put out their "we-are-so-cool-and-we-love-developers" face and invited everyone to be part of their platform blah blah blah.

That started around 5-6 years ago, and probably you (selectively) won't remember this either, but back then the first killer apps that Twitter had were third-party Twitter clients that made the whole user experience better. They were a hit because back then, too, the main Twitter UX was a piece of s... and these alternatives were so much better. And guess what happened to those products? Twitter pulled the same shit on them, they bought TweetDeck which was arguably the one with the most users (or the one that needed the money the most), and banned all other clients from their API with a week-or-so notice. At that time, that thing was even worse, because I would even dare to say that Twitter somehow was in debt with those developers because a significant contribution to the growth of twitter was driven by people going through all these third-party clients, that's plain treachery and there's even a special circle in Hell for that thing.

Now history repeats again and will repeat forever because the message from Twitter in that sense is very clear: we don't give a shit about our developers.

But now, it's good to see that things are finally turning around. Twitter desperately needs a killer app right now, because they've lost the hype, they're running out of money and investors don't eat anymore that "we will be profitable in ten years" crap. The only one way that Twitter could be hip again is, oooooh the irony, if another great product starts driving people back into using Twitter, but guess what? No developer will ever take Twitter seriously anymore, and that's just and sweet beautiful karma :)

Btw, it would be honest for you to disclaim about your relationship with Twitter :^)
> Go channels have a very, very rich semantics full of strong guarantees, which can't be relayed across a network.)

Any place to read up on those guarantees?
Many people still think that it's a 3-way horse race between sysvinit, Upstart, and systemd (which systemd has all but won). The Debian technical committee certainly acted like that was the case last year.
I disagree. Let's say that over the course of 1 second, there accumulate 100 lots to buy at 10 and 80 lots to sell at 10. Of those 100, who gets filled?

There are several different algorithms for determining this in practice today, of which pro-rata and fifo are the primary ones. Each has their own disadvantages and most give some preference to being there first, which reintroduces latency into the game.

I've seen some people speculate about a random allocation. I think this essentially boils down to pro-rata though, as you could game this by sending n 1-lots instead of 1 n-lot.

Exit tax? LOL. Good luck collecting. The operative part of that term is EXIT.

Citizenship that guts your wealth is not worth having. Any number of countries that don't have such avaricious tax laws would be happy to have a new, monied resident to spend money there.

Ah. No thats not a bug and sorry for the inconvenience.

It expects you to type your name again followed by your email. Basically, if something went wrong, you need to type both the name and email again from first principles - it's not waiting for just the email. Did I explain it right?

It's something that we would like to fix going forward.

Edit: Happy to sync offline in case I can help you further.
The answer is of course repealing the war on drugs. Maybe legalization of cannabis paves the way to the realization that regulation, taxation and harm reduction are much better ways of combating not only the violence and corruption that stems from the black market but especially the health issues.
How do I download this?
40 stories is probably more than a little absurd, but you can definitely take an area that size and build in high rise buildings.

Of course, you'd need do some infrastructure upgrades. It takes years to build high rise buildings. That is more than enough to add streets, buses that run to the nearest caltran stop.

>Second of all -- cut a deal with who? Not just Buena Vista residents, the whole city. Nobody wants that. A developer would have to be insane to even try.

That's sort my point. The whole bay area has a Luddite view on developing their cities. Zoning and permitting processes are designed to manage growth, but in California they are there to prevent it.
There is some evidence that dreaming is a side effect of defragging the memories of the day into long-term storage format.
The algorithm I use in 'EliminateVariables' is pretty ad-hoc and has built up as I throw more situations at it.

If you want to look up how the big time guys do it, I believe Mathematica's 'Reduce' performs full on quantifier elimination via cylindrical algebraic decomposition. There aren't many open-source implementations of CAD that I know of besides the venerable C-based QEPCAD.

Once the proper genes to make this work are identified by one group, how hard is it for another group to replicate the results?

I'm just wondering when drugs are created with this method if bioengineers will be able to 'easily' create reproductions of the yeast by following a template of the process, or if people in their footsteps will be mostly using clones of their original work.

Ask HN: Is there still market potential for PKI?
10-15 years ago, it was predicted that PKI (public key infrastructure) would be ubiquitous and used everywhere. Now, fast-forward 15 years - the Internet has some large CA's that issue certificates for https websites (and an increase in private PKI deployments as well), but it appears to me like a "scaling-up" of the same types of use cases, not any particularly drastic growth into new applications.

I'm trying to get a sense of whether the market and use-cases are already saturated or whether there are still new opportunities for vendors who create PKI solutions. Are businesses & enterprises still investing heavily in PKI technology and infrastructure? If so, where are the biggest opportunities for growth? What are the biggest challenges that an organization faces when rolling out a PKI solution?

Note: I'm not a security expert by any means - I'm trying to do some research on the field and thought about asking the HN community for help understanding the market.

Thanks!
Wouldn't it be difficult to attract top talent (or even mediocre talent) in that range?
The claim may or may not be true, but for me the word "toxins" has been so thoroughly poisoned by woo that I get a knee-jerk reaction just reading the title. The bar for anyone talking about cleansing toxins is like 200% higher because of all the bullshit that's been spouted over the last few decades.
It's really not that bad. Canada did it in the 1970s and it's still around, and we didn't revert to the stone age or anything.

SI units are already in wide use in the US, for instance for electricity (Amperes, Watts, Volts). For the most part, international trade has pushed US industries to adopt metric anyway: metric fasteners are used all over, in cars for instance. Also, countries that have switched still use inch-pattern stuff; in Canada we still use NPT threads and imperial size pipes with no ill effects; even in Europe they still use some imperial-threaded stuff.
Do you know of any resources to learn about tech lifestyle businesses?
Couldn't agree with you more. The question surrounding HFT should not be: "is this perfect?" , but instead should be: "is this better than before?".

And also, I'd point out that it takes hundreds of thousands of dollars to start a bank as well. Do existing banks have an unfair advantage over prospective start-ups due to these barriers to entry? Of course, but that's pretty much how the world works everywhere. It's not specific to HFT.
Oh I certainly agree with that, unfortunately a sizeable portion of the population doesn't. A significant lobby base in the U.S. fights actively against legalization and will throw tons of money at the current racket too.
Wouldn't it make more sense to wait for an acquirer to be found to release this statement?
At the risk of being self-promotional, there's another part of the rebel alliance of which USDS and 18F are the main players, and that is better technology contractors. ("Better" meaning, engineering practices and outcomes that the audience of this site would recognize.) There's Nava, and the company I co-founded, Ad Hoc. Greg and I were on the original HealthCare.gov rescue squad with Mikey et. al. We're still working on HealthCare.gov, but instead of helping to prop up the bad old code (which was necessary work to save the site and help actual people), we're rebuilding parts of the site from scratch, using things like Go, AWS, Angular. During the last open enrollment period over the winter, our code (healthcare.gov/see-plans/) had 100% uptime, served ~ half a billion page views, and had a mean response time of well under 100ms. (And _no_ garbage hiding in the 99th percentile.)

One thing I'll say about government work -- you're not really breaking new ground, from a technology perspective. (Unless you're at DARPA I suppose.) Don't come into thinking you're going to innovate in some bleeding-edge area. But government was left so far behind the consumer technology curve that basic, competently-executed, well-designed software that's fast is an _enormous_ leap forward. 2008-era web tech is sorely needed across government. In a way, that is the innovation: dependable software that reliably delivers services to people for whose user-experience has never been put on the same playing field as consumer online services.

If you're interested in being part of the rebel alliance, and for whatever reason USDS or 18F aren't right for you, consider contracting. There's enormous opportunity to make real change and see your code help others. Believe me, small teams can have a big impact on government, even from outside government. If you want to know more about Ad Hoc, get in touch (http://adhocteam.us/). We also have projects with the Department of Veterans Affairs, and state Medicaid programs.

I never thought I'd be a government contractor. I did the startup thing, and just happened to get roped into the HealthCare.gov rescue. I can tell you it's sometimes frustrating, but always satisfying work. And there are several avenues in.
I'm not really in the webdev-world, but I took a look at those things too because they also seem to have interesting concepts for my work.

From my point of view flux is pretty much a general architecture pattern. Relay and GraphQL seem much more tied to how facebook works and what there requirements are. It requires that you change your server-side code, which might not be possible for most parties.
You're making a couple assumptions I disagree with. Even when I was under 40 I knew of more problems that needed to be solved than I could possibly address. Every job I've had has exposed me to industry problems that were big... and you can found a company in an industry, be a single founder and then hire people who have domain expertise. Domain expertise doesn't mean one has to be a cofounder.

Also, consider does this domain expert have the background in startups that would be useful? Or were they being an employee in that domain?

I can think of a half dozen purely technical problems that would improve a billion people's lives-- and I'm talking purely software here.
Technically: not a clue.

Modern keys are complex things. Gone are the days where you can have a piece of metal re-cut for $5 at Home Depot. A replacement key for modern cars is an expensive proposition: they have to be custom-ordered from the factory (with proof of identity and insurance) then programmed by your dealer. Replacement keys for modern Audis/BMWs/Mercedes run $300-400 all-in. (Remember that scene from Gone in 60 Seconds? And that was 15 years ago. And also a movie.)

You can buy blanks, sure, but without programming, it's nothing more than a hunk of metal.

Is it somehow possible to "clone" a key? Never underestimate hackers, but it ain't easy. Per Brian-Puccio's use-case, unless the previous owner is presenting auto exploits at DefCon, you don't have to worry about someone having a copy of a key you don't know about. (And if they've lost it, you can go to the dealer and have it un-registered.)

Aside: Google around for articles on new car theft: you'll find that no thieves are copying keys or hot wiring or anything like that. In fact, the "new thing" is to get a signal amplifier that allows a car's keyless entry/start system to "find" a key that's sitting 100 feet away inside someone's house or office, then just drive away.

Hall of api shame: boolean trap
I've been that person, and that's exactly how I felt while I was doing it. I don't try anymore, the hours were for nothing and it's a complete waste of time.

A cofounder needs a very strong skillset, a life circumstance that permits them to drop everything for a startup without dire consequences, a level of enthusiasm and drive that to other people seems almost delusional, and your opportunity needs to out-compete all their other opportunities for more than a year. That's an incredibly rare person. There are probably more successful pop stars than there are people who fit that profile.

PG says if you're solo, you should look for a cofounder. When he gave that advice, it was because he observed that the majority of successful startups had multiple cofounders. But I don't think he bothered to consider the fact that approximately zero of those confounders met each other by going on a "cofounder search."
The post is saying that you don't need a cofounder for the subset of ventures that a very technical person can tackle alone. The types of ventures that YC funds are generally not plausible to tackle alone. There is no conflict between PG's ideas and this essay so long as you accept that there are ventures of differing scope, some need more than one founder and some don't, and YC generally invests in the latter.
Besides the fact that batch auctions don't say anything about matching algorithm (which you'd need to deal with to remove speed advantages), they don't do anything to address venue arbitrage (of which, this latency arb is just one form).

The only way to remove venue arbitrage is to only have 1 venue for trading everything. This is both a) impossible and b) not desirable.

Hi, really sorry that you feel this way. Delays on the order of a few weeks aren't unexpected at this point, but we shouldn't have people that have been waiting for a response of some kind for much longer than that. We're still growing the team (including those doing the recruiting and hiring) and we appreciate everyone's patience.

We can follow up with you to let you know where you are in the process, but we'd need some sort of identifying information in order to do that.
