Diversity focus should maybe be on diverse backgrounds not diverse skin tones. But its probably easier to do the latter as a company so that you can quickly look progressive to everyone in the industry (PR reasons, etc).
Most likely that is not the cause. They have been sheltered and kept from any form of adversity or harm. They are like zoo animals released back into the wild, they have no idea how to live without their cage.
I think the biggest difference is that modern games tend to be written for variable frame rates, stuffing floating point time deltas through equations.

A lookup table meshes much better with fixed frame rate gameplay, either with one entry per frame, or quantizing countdown timers of how many frames to wait to go to the next state.

> shareholders who hold their shares for a long time will get more votes

What prevents me from selling my vote, without technically selling my share?
Furniture has a huge warehousing problem. Buying furniture without seeing it is the pits.

That means successful furniture stores have become massive, so you can see the goods and buy immediately. In the midwest, Berkshire's Nebraska Furniture Mart and Ikea are are difficult to beat for staple furniture.

But once you see it at Nebraska Furniture Mart (or something from the same manufacturer) you get an awfully sweet deal on it online. That's the near-term play. The long-term play of getting people to buy sight unseen will be far more difficult; Wayfair has traditionally tried price and ease of shipping/returns, but that only goes so far.
So he's hired one programmer.
I wonder if it would be worth the square footage to showcase a limited selection of furniture in various corners of a Whole Foods.
I really doubt the problem is "nobody there understands the theory". More likely, as a large public company with considerable presales and aggressive public commitments, the ops people are probably being pressured to "just push a few more cars through manually today, while trying to improve the automation". It's easy to armchair-COO the situation and claim that you would halt the entire line (or problematic parts of it) for 30+ days unless/until every step is at 90%+ yield, but if Musk or the Board is saying no to that, you are basically trapped in a suboptimal local maximum that you know how to escape, but are socially unable to.

> Anyway here's a story about the Long-Term Stock Exchange, which is a new planned stock exchange backed by Silicon Valley venture capitalist types that will have "tenure voting," in which shareholders who hold their shares for a long time will get more votes.

This has been discussed already on HN, and I believe it's a bad idea.

All that would do would be to create two kinds of shares : the normal ones and those with high voting power. The market would then want to price them differently, and if you want to prevent long-term owners to sell their shares (for instance if they want to enjoy the increased value), then you are doing some kind of capital control.

It's just a bad idea. In a free country capital can be bought and sold : if you give voting rights to someone, he should be able to sell them, which would probably defeat whatever purpose you had when you gave those rights in the first place.
You'd be surprised how quickly those 500 multiply-accumulates per autocorrelation point add up... a 128-tap filter * 500MAC/point * 2 channels(stereo) * 192ksps is already at 24+billion FLOPS for a single track...
This is anecdotal so YMMV. I have a Macbook Pro 2017 and the shallow key travel makes me feel like its more accurate than the one on my previous Macbook Pro 2015 with longer key travel. Also, I feel like I am typing faster.
Another point is that, even if a bit of latency isn't noticeable (say, 20 ms), when added to other sources of latency it can make things noticeably worse.

EDIT: Which the original author said better than me:

> Another problem with this line of reasoning is that the full pipeline from keypress to screen update is quite long and if you say that it’s always fine to add 10ms here and 10ms there, you end up with a much larger amount of bloat through the entire pipeline, which is how we got where we are today, where can buy a system with the CPU that gives you the fastest single-threaded performance money can buy and get 6x the latency of a machine from the 70s.
I briefly thought about whether it would be a better option than Slack. However, Slack seems a little more polished in the areas that we actually use. The subtle, better design in places like the core chat experience aren't worth giving up.

I have used Discord quite a bit for gaming, but it hasn't proved a better option than Slack to me (at least in a work context).
This bit from the new Beauty And The Beast film sounds like Auto-Tune in a noticeable way to me:
https://youtu.be/6tMoE8siNo8?t=166

I'll try to walk you through what I'm actually hearing that makes me think there's Auto-Tune there:

- 2:50: Subtle, but as the first "oh" starts, it sounds like it quickly jumps from a slightly lower note to the correct one.

- 2:58: The word "part" has a classic Auto-Tune sound. The real recording probably went slightly off pitch as the note was held and Auto-Tune has made it perfect and a little robotic.

- 3:07: "Where" has a similar sort of robotic pitch slide sound as it starts as the "oh" did earlier.

- 3:13: "Discover" has a sort of a glitch in the middle as Auto-Tune tries to track across the 'k' sound in the middle of the word.

As someone else already said, songs in TV show Glee used it all the time in a fairly obvious (but still subtle compared to intentionally sounding Auto-Tuned) way.
Now that would be fun! I think it would be possible to achieve a reasonable typing speed given the right "keyboard layout" (aka the QWERTY equivalent for musical keyboards).
How well would MIRI work as a generic virtual machine for fairly simple stuff. Essentially I want to compile some type-safe code from a file and run it in a safe way inside of another Rust application.

I'm looking at various lua bindings as well as https://crates.io/crates/wren for this purpose, but I'm wondering if something like miri would work better since another path for compiling this language when real-time code reloading or sandboxing is not required is to translate it to Rust code and compile it with rustc, likely with a compiler plugin.
I've recently got rid of several extremely expensive mechanical keyboards to go back to a new ThinkPad chiclet. I am somewhat embarrassed to say it's been fantastic.
You can use your yubikey to store your subkeys (still generated on the yubikey itself) while your master key is stored somewhere else. If you lose your yubikey you can revoke the subkeys and generate new ones signed by your existing master key.
Being sick of bullshit is fine. Having the government regulate bull-shitting is a huge step towards tyranny.
Sounds like a good argument for the superiority of shallow keys. I've always liked Apple keyboards - actually used their wired USB keyboard for a long time specifically because it felt like typing on a Powerbook.
In the US at any rate you need a fairly significant amount of disposable income to meaningfully be free. Of course you are "free" to (attempt to) acquire this income, and most people reading HN will have already done so. But for a large swath of young people working low wage jobs, living at home because they can't afford rent, the notion of "freedom" might not seem that significant.

Haskell is typed lambda calculus and an amazing amount of syntactic sugar. One of the ten or so "aha!" moments of learning Haskell is realizing that so much of the language boils down to just \x -> let {...} in case {...}.

Which probably wouldn't be a bad way to teach Haskell, perhaps -- once one gets the general underlying form, understanding the rest is mostly just learning how the rest maps to that form.

Agreed. When I first used them I hated them, now I can't really use anything else.
The HAMMER2 docs talk about replication in a cluster, but not about RAID5/RAID6/ZRAID-style redundancy (e.g., n+r disks working together to allow up to r disks to fail with no data loss or losing ability to write).

Does anyone here know how/if this cheaper-but-slower kind of redundancy is addressed in DflyBSD?
That's effectively providing a definition of the latency he's discussing, not an explanation of why that's the sort of latency he finds interesting.

But I see he does goes on to say that he cares about game performance, rather than typing experience:
«
If, for example, you’re playing a game and start dodging when you see something happen, you have pay the cost of the key movement, which is different for different keyboards.
»

For me, I don't care about the time after switch activation, rather about time after the tactile feedback (the "click"). Ideally the character would appear on the screen at the same time as the click; not after, and not before. If a keyboard can 'cheat' and activate the switch before that and hide some latency, that's fine by me.
What is your opinion on having a business plan in order to raise money? Is it still a hard requirement, or are there new ways?
Yep, also capacitive and Hall-effect switches don't need debouncing.

How much disposable income do you need to be free? Cheap car, cheap rent, every form of media ever for about $50 a month. You can do that easily on 30k. If you can't make 30k a year, you've got a limited skillset, it's not anyone else's fault.

What's amazing for US millenials in particular is just how much we've got and how little we appreciate it.
Wayfair (and their various demographically-targeted brands, which include Joss and Main, All Modern, Birch Lane and Dwell Studio) is such a horrible mix of crap and quality. I believe they really have to overcome this to become successful.

One confusing and annoying problem with retailers like Wayfair, and the many other outlets (Overstock, Barcelona Designs and many others), is that most of their inventory is white-labeled; they buy no-brand products from Asia (China being the main one) which they sell under fictional brand names such as "Ivy Bronx", "Langley Street", "Wade Logan" and so on. You'll find the exact same products elsewhere under other fictional brand names. Often I've been able to find a product, such as a lamp, that's maybe $100 on Wayfair, being sold for $200 in a different online store; exact same product, made in the same Chinese factory, but differently branded.

The shadiness undermines the integrity of the brand, but it means it's also impossible to predict the quality of what you order. "Langley Street" is just a style, and isn't necessarily all from the same manufacturer. This confusion is compounded by the fact that Wayfair also mixes "authentic" products such as Flos and Artemide into their inventory.

But also, a lot of these products are just complete junk. So much is laminate, cardboard and fiberboard. There's surprisingly good, solid-wood furniture made in places like India and Thailand, but usually the online descriptions doesn't give you the full materials list. A lot of times you can get quality hardwood, but the joinery is terrible (lots of patching, glue, etc.).
It's worth asking why we make the distinction between "activists" and big fund managers in the first place. Shouldn't all fund managers be doing what's best for their shareholders?

You should check out John Bogle's "Clash of Cultures" (founder of Vanguard), he discusses this problem at length.

In general I'm inclined to agree with you though. This thing has a lot of hype around it because it's backed by Eric Ries, the "Lean Startup" author, but I don't really see a problem with the NYSE/Nasdaq in their current form. People overlook the liquidity, depth, and other benefits of such well-run exchanges; it's not at all clear to me that an average investor would be better off on this "long-term" exchange, where I'm sure volumes will be a lot lower, and bid/ask spreads will be wider than on a "bad" exchange with many "short-term" players, who, as a side-effect of their actions, create tons of liquidity for small-potatoes investors.

Frankly, I don't understand the point of this at all. There's nothing stopping a long-term oriented investor from holding shares a long period of time in today's markets. And there are real risks of corporations being too long-term focused. The existence of Amazon, at a minimum, should show that companies with 10-20 year investment horizons are tenable under the current system.
Nice write up on focusing on "postivity focus" and "helping teens' mental health" but seems like just another app training teens to seek social validation via an app...

Pascal, Assembly, C, Java, Python, JavaScript. Somewhere in there was Perl, but that seems to have been largely replaced with bash and Python for those types of tasks. Also somewhere in there was the dead-end Dart language, which I liked. I've been using TypeScript, but it does take effort not to revert back to straight JavaScript.
No one born in the mid-80s onward ever faced an outside existential threat like Hitler or the Soviets. It's not hard to imagine that people who only know relative freedom have a harder time appreciating that freedom. The grass is always greener elsewhere.

Fear is a good answer here, though phrases like "helicopter parenting" and "victimhood culture" might bely some existing biases by the author. Perhaps the fear of the "other" tribe are driving these shifts; after all, I doubt that anyone who says they'd be in favor of restricting speech feel like their speech will be restricted.

And it's also possible that a decade or so of gridlock is taking its toll. If this is what freedom looks like, could you blame someone for wanting to try something different? Not saying that's true of me, but I can see how it would happen.
I wonder whether this is object-level or meta-level wariness.

Object-level: thinking that people today are mostly awful, and that someone needs to police their behavior and choices (e.g. stop people from voting for people like Trump.)

Meta-level: thinking that the subcultures trying to police everyone's behaviour right now (e.g. Social Justice) are heavy on bullying, and it'd be nice if this sort of bullying was regulated/stopped/silenced somehow.

I know both of these effects exist to a certain extent in the US—but which one is specifically "millennials", and which is older people?
If you game on a mechanical keyboard, you've pretty much worked out exactly where the switch points are and will be working the keys in a fashion different to normal typing. So I'm not quite buying the way the measurements were made vs the purpose of the tests.
The generation that was in power while incarceration rates skyrocketed (which also means more people without voting rights) and that tends to have quite unforgiving attitude towards failures/mistakes complains that young people are not freedom loving enough.

I created a Kickstarter that made $104,000 . It's a map of all subway maps in the world. The project did really well and attracted the attention of ~25 Media Outlets including Wired Magazine, Gizmodo, FastCompany, Tech Insider, Travel & Leisure, Slate, Curbed, Cool Hunting, and lot more.

However, being a frontend developer that loves coding, I feel like I wasted a great opportunity of building a brand around it. The whole map was an attention grabber with the potential of turning it into multiple products for home, kids and even teenagers.

To the day I still receive a lot of requests to talk about it, people keep buying it around the world and is currently being exhibited in a museum in Beijing.

I would love to sell this to a great Marketing team / Visionary that can build a multi-million brand with it.

1) I built an app to help me form habits on a daily basis: https://github.com/ioddly/meditations . Pretty simple, minimalistic, but having it open every time my computer does makes it low-friction to log all these things. There are loads of these; I wrote my own for fun and because I wanted to keep the information encrypted, locally.

2) I've started unplugging the internet. Like I literally pull the ethernet cord out of my computer and turn off my phone. I do it every night so that when I wake up, I code for about 4 hours without it. This has been the biggest boost to productivity and happiness I've had in a long time.

Two issues with this so far:

a) Sometimes I hit a wall where I need to look something up before I can proceed, but I've never run out of work that I do know how to do. So I just write it down to search for later and work on something else.

b) I'm not sure how this would work with paying clients, managers, and so on. So far I've only done this on my own projects, in between clients.

Great points!

1) To me, security goes hand in hand with your point on mental models. It's hard enough to imagine how a bad actor might abuse a simple system you know well. Scale that up to a complicated system that no one understands and you've got a real problem.

2) Absolutely. For one, I'd want UI separated from data and logic such that you can easily tie programs together Unix-style.

Today, programs have a hard time interfacing with each other. And portability is nasty too. Maybe we could make the _ideas_ behind a program portable?

People quote “Programs must be written for people to read, and only incidentally for machines to execute.” But has this ever really been true? Take any function in your codebase and imagine you were asked to explain it to a friend. Does what's written out in code resemble even remotely what you'd say to them, draw out, or demonstrate? If the representation were good enough, you could just lift out the key idea and add it to your program.

3) I've used LabView a little, and it does kind of suck. Probably because they focused on making the logic itself be visual. When I think about merge sort, I "see" the recursion and merges, with chunks of the list flying around as the stages unfold. I don't see a flow chart or a circuit diagram. I'd bet most people do something similar.

Really, code is a pretty reasonable way to write out program logic. What we're missing is that visual intuition behind it, that mental model we force people to build up imperfectly.
> But your system isn't more free. Universal healthcare is obviously the most free system.

Lol. It is more free, as in freedom of the individual market agents to self organize and direct resources without a centralized authority. There is no 'free' lunch, by the way.

> Why would we keep twisting and twisting this market?

If you reread my comment, you may find that I am only suggesting we undo the twisting.

> And where does the strange confidence come from that we just have to tweak it like this and then it'll all work? We have examples of well functioning healthcare systems. They're universal.

As I said, the US generates most of the medicines and techniques used by the smaller countries with touted, socialized healthcare systems. And while some of them work better in small scale countries, they are far from perfect (and note how much worse they get with larger countries, like England).

However, even if we all got free lunch in your socialist utopia, people still die in their seventies and their health-span is typically a fair bit shorter than that, becoming dependent on universal drugs (Medicare) for the last decade of their lives. Why not aim for the best solution? Medicine has a long way to go, and a freer market is the most powerful force to advance it.
I'm appalled that everybody carries around a real time yearbook. High school seems to never end. I shudder the effect this app will have on the self esteem of the user.

We didn't know tobacco was harmful back when everybody was doing it. We didn't know cocaine was harmful back when it was the thing. We also don't know about the sort of damage and stress of the human psyche with these engineered digital toxins.
You are extremely ignorant of the cost of living in the US if you think 30K is enough to live on.
Ask HN: Is it poor form to clone a startup with little to no competitors?
If you find a startup that seems to have little competition and you feel capable and inspired, does it make sense to create your own version?

There are many assumptions here, but I think we can start with the broad question.

> Assume that the startup to be duplicated has validation - via funding or discernible growth/activity.

> Assume that the startup is in a growing/nascent/not-well-
served space/industry.

> Assume you are technically capable of creating a clone in X amount time, where X is < 1 year (or with help, even less).

> Assume the startup is primarily providing a connecting service for groups with different interests, like Meetup (admins organize groups).
Yes. The original premise of the article is:

> The value of a share of a company is equal to the market's expectation of the present value of its future free cash flows.

Emphasis on "expectation". It may change wildly in the short term; reasons include hype, speculation, and news that has only short term relevance.

Flaps do increase drag (especially at higher speeds) but they also decrease the stall speed which is why they're deployed during takeoff and landing-- they allow a slower takeoff speed. In effect, at lower speeds, the lift increase has a bigger effect than the drag.

There is a fair amount of Hollywood according going on with what overhead is included in those costs. Medical groups for example often have profitable out patient facilities in the same area as s failing hospital.

Many hospitals do operate just fine with high numbers of Medicare patients and few private medical facilities reject Medicare patients. Remember, when a 3rd party agrees to cover costs the incentive to lower costs gets messed up.

However, many hospitals also have issues which is why there are supplemental payments.
