grumpy8··on Electron 7.0
I don't know why that is, but in the end, aren't web browsers using the native os widgets for input text, etc.?
grumpy8··on Tesla Q3 Financial Results
imho was still a fair question, no need to downvote. Not arguing with the index argument, but I've had finance "experts" trying to pull similar tricks on me by using weird years, etc.
grumpy8··on Quantum supremacy: the gloves are off
Overly simplified, but in classical computing, a bit is an abstraction representing a 0 or 1. In quantum computing, a bit IS the electron (or some other particle). And electrons are weird and can behave in very surprising ways. Quantum computers are controlling these electrons allowing to do things that classical computers can't. One example of such thing is Shor's algorithm which, taken from wikipedia, "is almost exponentially faster than the most efficient known classical factoring algorithm".
grumpy8··on The next big thing will start out looking like a toy (2010)
I have a question for those who were there at the very beginning of the internet. I heard that many were skeptical about both personal computers and the internet.. did it feel the same as it does right now with crypto-currency/quantum-computing? I wasn't there, but on my side, it feels like people were able to use internet right from the beginning, whereas there's a bigger leap to using crypto/quantum. Is it just that the infrastructure isn't in place to allow normal people to do easy things?
grumpy8··on Ask HN: Feasible Alternative to the MacBook Pro?
Somehow I imagine that the same people who hate macbooks probably also hate fancy restaurants where adding salt is an insult to the chef
grumpy8··on YC Interview Tips from a Former YC Partner [video]
no bullshit feedback and help from very experienced founders and execs, which they offer for free and willingly because back then when they were first time founders they were helped by other amazing experienced founders.
grumpy8··on A brief rant on the future of interaction design (2011)
>> without addressing the obvious point that an iPad can be a million things other than a piano.

I think you're missing the point. He's saying we should work toward creating a new kind of technology where the ipad would really feel like a piano when you're on the "piano app", but feel very differently for other apps.

What you're saying is that you don't think that such technology could ever exist; BV thinks otherwise and he's working toward that vision. He's also saying that we shouldn't take the future for granted as if a technology will just suddenly appear. It takes hard work, funding and a clear vision.

I can think of a few ways about how we could add tactile touch to a dynamic interface (I.e. turning a piano 2D screen to a real experience). VR is going in that direction (to see 3D from a 2D screen) and you can imagine some sensors at the tip of your fingers where depending where you touch you'd feel something different. Again, that's just an idea, there are many ways it could be achieved.

The author of the essay is the founder of https://dynamicland.org which implements what he's talking about in this article.
grumpy8··on Programming Idioms
I'd look into "webdesign-idioms"
grumpy8··on V8 adds support for top-level await
>> What would you suggest instead?

On the front-end, I'd do a call to the server. On the server, I'd use a database transaction for that.

But I get your point. The way I deal with race condition in redux is to have a mutex. I.e. While something is being fetched, any call to this command is either ignored or queued up.

I use redux-saga for the "race-condition" and general flow, and call the various async functions from within sagas.

grumpy8··on YC’s Early Decision makes starting a company easier for graduating students
It's about risk management. When you're young, there's really not much down-side in starting a company, and the up-side is extremely high. Also, even if the startup is a total failure, the experience combined with the people you've met totally compensate for the few years.
grumpy8··on Scott’s Supreme Quantum Supremacy FAQ
Extremely simplified:

>> in an electronic circuit, what is a qubit?

It's not an electronic circuit, it literally is an electron or a photon. And it's using that particle's properties to do "superposition and all that jazz".

You can't put too many next to each others because they start interacting together because that's what electrons do when they get close.

grumpy8··on Ask HN: How to keep yourself accountable?
Had a similar problem, but just do what works for you, i.e. work with other people and be transparent and public about your deadlines/milestones.
grumpy8··on Amazon orders 100K electric delivery trucks from Rivian
Never heard from Rivian before. I'd have expected Tesla to get that contract, but I guess if Amazon invested in Rivian it makes sense to order 100k vehicules and make sure that company is successful to get a huge return.
grumpy8··on IBM will soon launch a 53-qubit quantum computer
The gist of it is:

>> that can hold more than 2 states

--> that can hold more than 2 states AT THE SAME TIME (in weird quantum conditions)

So you're not trying 00, 01, 10, 11; you're trying [00|01|10 |11] at the same time, as well as other state in between 0 and 1.

grumpy8··on Test-driven development: A great idea hiding behind a terrible implementation?
Agreed and learned a few things. I think you should blog more :]
grumpy8··on Warcraft 3: Remastered Will Work with Old Custom Maps
My theory is many great people left from blizzard.. they're trying to milk what they can with as low as budget and a team as possible.
grumpy8··on Warcraft 3: Remastered Will Work with Old Custom Maps
Same! I'd be happy to pay for these small nuggets of blizzard history

Reached 2500 in overwatch, been hard stuck around 1900 for a few seasons
grumpy8··on Water found on a potentially life-friendly alien planet
>> It probably sounds less than ideal to you and me, vs. living on a planet, but it probably wouldn't be so bad to someone born in that sort of environment and is used to it.

Yeah, and also at some point, it won't matter what's ideal or not.. it'll be about survival.

grumpy8··on Water found on a potentially life-friendly alien planet
Or sending a HUGE human civilization spaceship somewhere.. maybe it will outlast the earth?
grumpy8··on Where Quantum Probability Comes From
I love this website so much (quantamagazine.org). The design is great and the articles are amazing.

real nice; I love how we see other people.
grumpy8··on How to get into Y Combinator according to the founders that did get in
> How much time and effort did you put into the application?

Spent a whole week on it because the questions were really good and had to do a lot of thinking and research.

> Do you need traction to get into Y Combinator?

At its core, to get in YC you need an insight to build something that has the potential to be a $1B+ company. Having traction is great because it shows that this insight is grounded -- but this isn't required.

If you have no insight and no traction, then you need something else exceptional to convince them to invest in you rather than the idea.

> What are some tips for writing the written application?

Don't bullshit and get a founder from YC to review the application. Unlike most people, you don't need to "bullshit YC" to get in.. they actually want to fund you as long as you can prove that your insight is grounded and made significant progress relative to where you were a few weeks earlier. Also, be concise because they're reading thousands of applications.. if as the CEO you can't be concise, it's kind of a red flag against you that you won't communicate properly to customers, employees and investors.

> Bonus tips on how to get into Y Combinator

Don't read too much into "How to get into YC" things. Be ruthlessly focussed on working on your product and talking to users. Better to fail fast and move on to a different product if users don't love it or you're not solving a major pain point.

grumpy8··on Show HN: A Senior Engineer's CheckList
>> extreme ownership

This is my biggest pet peeve with junior developers. I find there's a total lack of ownership about making sure the feature is completely wrapped-up (not just the code, but the tests, the metrics, that it's shipped, that it's correctly marked as done and communicated, etc.)

I find they /expect/ that someone else at the company will review and make sure everything is done and safe, rather than be proactive about it.

grumpy8··on Wunderlist founder wants to buy his app back from Microsoft
It's far from accurate, but an easy way to think about it is:

200 000 000 users * $1.

grumpy8··on TypeScript vs. ReasonML
IMHO the biggest reason to use TypeScript rather than Reason is because, in the end, it's still javascript and it stays within the same ecosystem. As great as Reason is, it's adding too many dependencies. The only time I'd go with Reason instead of Typescript is if the developers on the team are already proficient with OCaml. It's going back to the "Use boring technologies even though some things suck as it's better to deal with known issues than unknown issues; the grass isn't always greener with new technologies, just different things that suck".
grumpy8··on Ask HN: How Do You Read?
I'm always reading about 5 books in parallel, depending of my mood, the context and my focus.

Usually:

  - biography or fiction book that I listen to while driving

  - hard science book when I know I can focus for a few hours. (I.e. Quantum mechanics or advanced algorithms)

  - 1-2 business or technical book that I read on kindle (Either from PC, ipad or my iphone)

  - various blog or pdfs open on my pc / iphone
The business / technical books are the ones that I read the fastest because I can skip useless chapters and they're always one-click away when I have a few minutes to wait.

The hard science are the ones that take the most time.. sometimes it can take me weeks to read a few pages, and I often need to do side research to understand what I'm reading.

I think the fact that I have different choices help me read more because if I'm not in the mood for one thing there's usually something else interesting. If I don't have interesting books then I'm more likely to waste time on reddit / HN / twitter. (I still browse HN from time to time when things are compiling though :D)
