How can a simulation be more accurate than what it's simulating?

Check out Karabiner Elements (https://pqrs.org/osx/karabiner/).

You can create a rule to change caps lock to control if pressed with other keys, else escape if pressed alone.

I have no affiliation with it, just ran into this issue myself and it solved it for me.

jnevelson··on Tesla Q3 2018 Vehicle Safety Report
I'd be curious to see if the crash rate is similar to the crash rate of other cars in the same class (BMW, Mercedes, etc). Is it possible that people tend to drive more cautiously in a more expensive car?
jnevelson··on Liquid water 'lake' revealed on Mars
> Without spreading the achievements of science and technology to everyone on the planet, humanity is doomed.

Forget ethics/morals for a second - this is just patently _false_. It depends on your definition of "doomed", but humanity as a whole needs only a few people to survive in order to not be doomed (defined as extinct).

It'd be easier to argue your case without hyperbole.

jnevelson··on SpaceX’s Falcon Heavy successfully launches
Those "largely-irrelevant sci-fi stories" are partially what helped inspire the people that accomplished this.
jnevelson··on Spotify files for its IPO
Ignorant question (I'm not very familiar with the music business): what do the labels provide to the artists - why do they need to sign with Time Warner/Sony/etc at all, rather than just releasing their music to all distribution channels (Spotify/Apple Music/etc) themselves? I understand for smaller artists the labels can help provide advertising to them, but the larger, well-known stars you mention seem like they should have leverage to negotiate themselves?
jnevelson··on Ask HN: Who's switched from Chrome to Firefox 57?
Haha. I can see how someone would think I'm trolling, but I assure you I'm not. It's a pretty deeply-ingrained behavior that I perform quite often, so yes, it does make a difference. FF57 is still not so much better than Chrome (to me, anyways) that it's worth dealing with re-learning this for me.
jnevelson··on Ask HN: Who's switched from Chrome to Firefox 57?
I tried (again) to switch to FF yesterday when 57 was released, and unfortunately still ran into a known bug that makes it practically unusable for me: FF treats underscores as punctuation that breaks up a word, so given text "foo_bar", if you double click on "foo" or "bar", it doesn't select the entire word. This goes against all conventions of Chrome, other text editors, etc. It seems trivial, but as developers we deal with underscores a lot, and copy text out of our browsers frequently.

There's been a bug open about this for 15 years now: https://bugzilla.mozilla.org/show_bug.cgi?id=196175

jnevelson··on What It Costs to Open a Restaurant in San Francisco
Not all calories are created equal.
jnevelson··on DevOps is a culture, not a role
Here's my point of view as someone who's title currently is "Senior DevOps Engineer", and used to be a software engineer for many years:

DevOps has multiple meanings - in some (usually smaller) companies it can be thought of as a philosophy in that all developers are responsible for managing production infrastructure and their deployments. As a company scales, and the codebase grows, people have to start specializing. It's just not feasible for everyone to have perfectly overlapping skillsets and be completely replaceable by each other. It happens with frontend/backend, and it happens with "DevOps". I focus on our production infrastructure, making sure deployments are smooth, our database has backups, etc. That doesn't mean that other developers are completely detached from our production environment - if there's an issue in production multiple parties are involved in working through it and fixing.

I personally interchange the title DevOps Engineer with Site Reliability Engineer, Infrastructure Engineer, Ops/SysOps Engineer, etc. Different companies have different titles, but I'd wager that the majority of those positions tend to perform work of a similar nature. Depending on the size of the company, some may specialize even more (i.e. a large company may have SRE to focus on production/monitoring, and someone else to focus on deployments). It definitely varies company to company, but by and large I think it can all be grouped under "software operations", which itself is a subset of software engineering.

jnevelson··on A lawsuit over Costco golf balls
I'd be very interested in hearing more as well. Email is username @ gmail. Thank you!
jnevelson··on Thank HN: From Google form to $1k in revenue in one month
I'm not even the target market (too young), and this is my favorite job board already. Very fast to navigate around - speed IS a feature! Also love how granular the locations are.
jnevelson··on Building Your First Atom Plugin
For me it's not so much the slow start-up time - that I can deal with since it happens so infrequently - it's the intermittent lag when typing or selecting text, and the high memory and CPU usage. A text editor should not be consuming 100% of a CPU core for almost any length of time and making my laptop sound like an aircraft carrier.

I love the concept of Atom (OSS text editor is awesome!), but it's bordering on unusable for me at the moment.

jnevelson··on Apple Encryption Engineers, If Ordered to Unlock iPhone, Might Resist
And this threat right here is exactly why encryption is so important.
jnevelson··on YC Stats
Need to take dilution into account here. If we assume a (optimistic?) 1% stake, that's $650M.

YC recently (1-2 years ago?) started giving 120k. Before that, it was 10-20k. So let's say half of what you said is the total investment = 65M.

That's a 10X return. I actually was expecting higher. Am I missing something in my numbers?

jnevelson··on Google announces Android for Work
I don't think the "average business manager" is going to be reading a Google blog post.

jnevelson··on Etsy acquires Grand St.
Took me a bit to figure out, but you can click on 'store' in the upper right. I would think that 'home' would/should take you there, though.
jnevelson··on Lens Blur in the new Google Camera app
So Google basically took what Lytro has been using hardware to achieve, and did it entirely in software. Pretty impressive.
jnevelson··on Programmers At Work: Bill Gates (1986)
Interesting.

"...our present thinking is that we won’t have to increase the size of our development groups, because we’ll simply be making programs that sell in larger quantities. We can get a very large amount of software revenue and still keep the company not dramatically larger than what we have today."

jnevelson··on [dead]
I think you guys are in agreement. Of course luck plays a role, but you have to put yourself out there to give yourself a chance to get lucky. The best entrepreneurs recognize lucky opportunities when they are presented - but they had to work to get to that position in the first place.
jnevelson··on Model S Fire
In both examples that you provided, the cross-sectional area over which the force is applied is greater, so the overall pressure is lower. The magnitude of the force applied isn't the only parameter by which to judge the structural integrity in this particular instance.

jnevelson··on Creator of xkcd Reveals Secret Backstory of His Epic 3,990-Panel Comic
And yet arrogant enough to think that we're so much smarter and more advanced than those that came before or all other life forms we share this planet with.

BTW, not saying I disagree with you - just a counterpoint that can be made.

jnevelson··on Tesla to triple supercharger network by the end of June
I see the super chargers (and electric cars in general) more as a way of putting many gas stations out of business. Who will need to ever "fill up" their electric car when they can charge it over night each day? The only time you'll need to charge on the road is on long trips, which is exactly the void that the superchargers fill for Tesla.
jnevelson··on Bitcoin Is Fundamentally Flawed
"Eventually the Bitcoin economy is going to run into the problem of its algorithm and the Bitcoin-hoarding because; there will not be enough currency."

There is an oscillation process at work here - as people hoard bitcoins, the value of each individual bitcoin increases. People will then sell off their bitcoins in exchange for a higher price than they initially payed for them, thus increasing the money supply and allowing others to buy into the system. Am I missing something here?

jnevelson··on Show HN: We got fed up with Airbrake, so we built Coalmine
One recommendation I have is to open up the number of events/minute. You should have at least 1 plan where that number is unlimited.
jnevelson··on Induction: A Polyglot Database Client For Mac OS X
There's nothing particularly special about it, except for the fact that it just works significantly better than any other RDBMS GUI program I've ever used. The UI is great, it's fast, it's simple to use, and I've never found a feature I needed that it doesn't already have.
jnevelson··on Death sentence for Iranian web programmer
Given the utter insanity of what happened with this guy, I don't think anyone is in a position to judge what Iran gives a crap about or not.
