You probably should have started with, "Hi, I'm a/(the?) founder of Mobilecoin."

Edit (because this comment was down voted and flagged): Parent's HN profile says they are 'running' Crypto Lotus. Crunchbase lists only one General Partner at Crypto Lotus [1]. That same partner's LinkedIn lists them as a founder of Mobilecoin [2]. At a minimum the parent has a strong financial relationship with Mobilecoin and is probably the founder. HN generally frowns on not disclosing a relationship like that in threads about companies.

I really wish they'd bring back some trams though. A lot of our roads are incredibly wide, they could still have trams going up High Street, thru Caversham etc. I wish Dunedin would spend more effort on public transport - I loved how many people used the buses recently when they had a free day!
I think you make a good point overall, and I think anthropogenic global warming should be open to questioning. It should be be able to prevail on its merits in the face of competing theories.

However if you are speaking in terms of what "we know", I think you have to acknowledge that the scientific consensus is that AGW is real. That doesn't prove it is true -- nothing in our world outside of math is ever truly proven. But it puts the burden of proof on doubters to not only provide a different/better theory, but also to explain why everyone else is wrong.

If your position is that everyone else is wrong, but the "actual causes" are not known yet, then you just end up looking like someone who has their thumb on the scale, and is invested in a particular outcome.
As I understand the phrase, "99% accurate", this is correct. However, I gather that to statisticians this phrase could mean other things. I think the source of the ambiguity comes from whether or not everyone gets tested or something along those lines.

To me the phrase should mean that when I test people who have the disease then 99% of the time I get a positive result and when I test people who don't have the disease then 99% of the time I get a negative result. That seems the most reasonable interpretation but I'm not a statistician.

How do you create laws that both

a) Protect a vulnerable class of people from being fired (say over 40 people)

and not

b) Require 30 forms when firring someone in that class for perfectly valid reasons

Seems really really hard to hit both. You need to err on one side or another.. which way do you go?
Like one person it the building who volunteers (or is compensated) to sign for all packages? Not a bad idea. Makes a lot more sense than the startups where you have packages shipped to a receiving center and then a random worker redelivers them to you.

I think fraud might be tricky. If my neighbor steals my packages, what do I do? Doubt the carrier's insurance would apply.
Startup Visa Draws Only 10 Applicants as Trump Throttles Program
I've done what's described in the article for years. In fact, I've never once installed Facebook or Twitter on my iPhone. My general rules-

- No social media, at all. News only for entertainment, and news sources (fed through Feedly) have to be new sources, not politics-masquerading-as-news. Things happening, not things people are saying.

- No notifications enabled other than texts and calls.

- Do not disturb set for 10PM-6AM, allowing favorites to call through (wife & family).

- Single page homescreen to keep it clean, tidy & organized.

Mine is used for utility, and like most things in modern society, there's enough power if you aren't very intelligent to get controlled by the technology. You have to be capable of seeing through the tech, and not become its slave. Eternal vigilance is the cost of freedom I suppose.

I rarely look at my phone, I do have games, but they are opened less than once every 12 months. Looking at what I have installed now, I have Super Mario Run, Breakout & "Faby Bird" (a Flappy Bird remake). I see no need to remove them when I don't find them to be a problem or damaging like social media is.

Why do I have a smartphone then?

ApplePay, remote home & PC controls, GPS maps, online banking, Lyft, Exxon Mobile SpeedPass+, Find My iPhone to know where my family is if they need me, are all invaluable. Those are the things I use a smartphone for.
Sure, a hierarchy of complexity. You don't think such a thing would exist?

Why are you trying to seek out a hypocrisy angle in my arguments? I feel like that's a somewhat boring way to go about this.

I think the point of the prologue in Diamond Age is to act as gravestone.

Bud (Nell's father) is the prototypical cyberpunk character. And he's literally killed off by the events of that chapter. He plays no role in Nell's life, he's never brought up again, it's Stephenson saying this novel is literally post-cyberpunk.
My argument was more that there is no association between a theoretical "hierarchy of care" and actual, real brain sophistication. If there were, people would for example eat cats before they ate pigs.
Oh for sure, I was just pointing out just how drastic the HR filter can be. I might have thought referrals would make a 2x difference in rates of getting an interview right? But no... it's much more stark than I personally expected.

The literal answer to your question is, "no, generally not". That a greater emphasis on statistics should be included in science is certainly the case, but then there is a school of thought that know a little bit of frequentist statistics is better than knowing none at all. But regardless, I am fairly confident that most scientists (or engineers) do not actually learn this as juniors (or seniors) (or Ph.D's)

Yes, it is. The fight for jobs in the academic market is fierce; there are far more people looking for academic jobs than there are positions.
I don't understand - was this a traditional fund raise, or an ICO? I had thought ICO at first, since it's a crypto currency, but the article doesn't come right out and say it.

If it's an ICO - how does that work, exactly? People buy some amount of the coin at a valuation, and then they'll be able to use it later once the actual application comes out?
My grandfather did the same thing. Carried a half-empty pack around in his jacket for weeks after he decided to stop. I always thought that was the hard way to do it, but maybe not.
> I can't really find yield numbers

This is not surprising - this is trade secret information as it directly translates to profit margin for the process. AFAIK nobody publishes process yield information other than vague handwavy percentages.

You should also expect percent yields of most processes these days to be pretty poor (numerically): each step brings its percent breakage along, so at 100+ steps for these current processes, you're losing a significant fraction of chips. (Even if all of your steps yield 99%, you're down to 36.6% yield after 100 steps, so it's really important to reduce the number of steps as well as their complexity.)

For a process to be profitable it doesn't need to have a perfect, or even "good" yield though (and so-called "perfect wafers" have been vanishingly rare since about the 14nm process step). I've read documentation about very old processes with yields of 60% that were considered "good" at the time, so 10% might not be a terrible overall yield at this process node (e.g. if we take our 36.6% yield example above, 10% total yield would be of 27% of theoretical - certainly room for improvement, but better than many pharmaceutical processes).

This underlines the importance for the switch to EUV - a dozen or more DUV multi-patterning steps can be dropped down to a single EUV step, which eliminates losses along those multi-patterning steps.
The layout is also broken on Firefox mobile for Android (not a good impression for a website for an Android phone...). The text on the first slide runs off the screen, the second slide is just blank? And the slide with tech specs has the text all jumbled together and overlapping.
In 2016, we developed several very large applications using Redux. The clarity/simplicity gains quickly evaporated as the system grew in size. The experience led me to develop an alternative [1], which I have shared here before. We used it for several production components and the productivity and testability gains were very clear.

This is more the line I was going down - I think in the future it will be difficult to justify, morally, the killing of any mammal for its meats. Especially when grown meat alternatives become affordable.

I say this as a staunch carnivore. I just don't see how it's morally sustainable. What if we develop methods of chemically induced greater intelligence, and a Peta activist goes to a farm and injects it into all the cows? Shit like that are what I think will eventually drive the world to vegetarianism. That or species extinction...
If that's the case, I'm even more confused as to why he posted this, not less.

As an engineer, my options for prototyping boards are quite expansive because I have money to spend and computer tools at my disposal. These choices range from old-school etching of PCBs; new-school CNC engraving of PCBs; cheap, slow boards from China; to expensive ($1000), fast boards from the US.

Doing this on paper with copper tape is a cool hack, I just don't see a lot of benefit over other options.
The implication is that if you create the technology for “good” then you also make its misuse possible.
You've posted a bunch of flamebait to HN already. Could you please not do that? It isn't what this site is for, and we eventually ban accounts that do it.

What's sad is that the majority of electric buses being purchased both in America and around the globe aren't manufactured in the US.

We have a Silicon Valley company, Tesla, that kicked off the world-wide move to battery powered autos. Why is there not a US company recognized as the leader in buses?

There are a few California companies on this list but they're tiny. Here in Michigan the leading player is French and they're self-driving as well. I wonder how American manufacturers failed to grab this market. Detroit should have owned this industry.

Sounds harsh. I started a stream with a good mic and HD cam and within weeks my mannerisms were better. I’m also realizing a verbal problem I’ve always had and nobody has confronted, even dentists, despite the obvious issues (dentists, doctors, phys trainers to a degree, would have all noticed). I am a good researcher and honest with hard truths, and that’s led to some interesting oral exercises and progress, actually recorded a first draft last night talking about oral collapse effects.

I went with the Blue Yeti... can’t speak highly enough... my first mic, so ymmv vs. other condensers, but the sensitivity of the device is paranoia inducing... high gain and I can hear myself breathing loudly across my apartment.

GL with pro help, my $0.02 is that self feedback can probably carry you till you need specific feedback.
Most people don’t study history (or don’t learn its lessons) and as the saying goes, are doomed to repeat it. I think it’s worth remember ping that plenty, whatever they say publicly, are just trying to get rich and don’t really care how. $30million from exploiting the next fool spends just like any other money, as long as you’re not the last fool.

That is picking nits :-) Not only is China rapidly building nuclear power plants, containing the emissions of one plant burning coal is easier than containing the emissions of the 10,000 buses that plant provides power to operate.

There is also a benefit to China converting from oil (something imported[1]) to coal (something available locally[2]).

> If 2 candidates arrive to the optimal solution, the one that did it much faster is the better candidate.

This is _a_ metric but I wouldn't bet too much on it. I know lots of people that come to optimal solutions to "algorithm type" _much_ faster than I do. I'm pretty slow at that type of stuff. But... its just such a small part of what makes someone a good programmer. Building out a medium to large application requires balancing a lot of trade offs and figuring out how to keep things simple. I know seasoned, quality algorithm solvers who honestly just repeatedly churn out garbage applications. And they can tank the productivity of an entire team of developers in their wake. I don't know how you test for that, but I can promise phone screening for problem solution time isn't it.

Point taken, the intention is to make each command more succinct and we overloaded the functionality of `kr add` to do so.

`kr add` will add your public key if no members are specified. The user being modified is whichever is being logged into. So if you have an ssh alias "bastion" that specifies user "jump" in your SSH config, `kr add bastion` adds your public key to user "jump". Just like when SSHing into a server, you can override the default user in the form `kr add user@bastion`.

This is only the first iteration of `kr add`, and we will be adding more advanced access control in the near future, including authenticating as one user but modifying another.

Totally agree with 3., we'll add this to our roadmap.

Thanks!
I remember them in Auckland at about the same time. Every trip it would lose the contact with the overhead lines and the driver would get out with his stick and move it back. I also remember for the being very quiet, except for a quiet hum and whine inside. And they accelerated very fast.

Was on a team at a large company - and the architects had a decree that everyone must use React - good decision. Except one problem was that everyone was just using Redux like it was part of React or something. I don't know how many components that had to maintain their own state got stuck in Redux nightmare land where special keys were being used to keep each component separate - it was a complicated mess inside the react component. This component didn't map to a single concept of state, instead many "copies" and different versions of that copy could be on the screen at once - and no one really "got it" that they were feeding really deep into a major anti-pattern.

I kept pointing out to members of the team that even Dan Abramov's post about maybe not needing Redux... but it fell on def ears like I didn't "GET" redux.

I totally understand the enticing time-travel feature, but I think too many people jumped on the ship before it was ready for the use-cases different folks had in mind.
Anyone else think that in the “neutral” photo, the actors look like they’re about to kiss?

No, really. I blame an overexposure to pop culture. That particular framing, with the characters staring into each other’s eyes, combined with the sense of stillness implied by a photo, to me feels reminiscent of a certain overused stock scene in film…

And there’s reason I thought of film. In a real-life photo, people are usually either looking at the camera (if they’re aware of the photo) or farther away (if they’re not). You wouldn’t usually see that kind of perfectly framed side shot.

So I’m not sure all the children were really “misreading” the emotion in the neutral
photo. (Unless, of course, it’s just me who’s misreading…)

It doesn't matter how many DNS resolvers you have. If you can spoof BGP, and use it to spoof the DNS resolvers, and the authoritative name server, you can stand up your own DNS that says anything you want it to say.

The only thing you cannot do is fake out DNSSEC. If you use a TLD which supports DNSSEC, you can make sure records have to be signed with your key. If fake DNS records aren't signed with your key, and the CA uses a validating stub resolver, and the CA is checking for CAA records, they will reject the attempt to create the cert. In theory.

Here's the thing. The CAs know about these flaws and are still not providing more secure ways to prevent these attacks. How could it be more secure? The domain registrar could accept a public key from you at the time of purchase. At that point, nobody should ever be allowed to generate a cert anywhere without you signing off on it with your key. Is this some magically impossible technical challenge which mere mortals can't comprehend? Hell no. They literally just need to write an ASCII file in a database next to your domain name. But we aren't demanding it of them, so they aren't doing it. So attacks like this leave everyone vulnerable, because nobody cares enough to fix it.
Why stop at technology?

You can use pretty much anything for good or bad. Rocks, Nitrogen, Automobiles, Thoughts.. it's an endless list.
Availability of the class != assurance that every citizen has taken it and passed.

Furthermore, most tech companies don't even engage or give the opportunity to engage in the "negotiation" part of the contract forming process.A EULA or ToS document isn't a meeting of equals. It's a salesman rushing you down the hall telling you to sign, sign, SIGN!

In fact, if nothing else, technology has provided one of the finest examples of a cautionary tale with regards to a "delegatory" legal profession (a profession where legal literacy is contained to a specialized sub-population and where literacy of the full population in the intricacies of the legal system cannot be assumed). I'd be interested in seeing a chart of user accounts of major software platforms or providers at time of ToC/EULA change in order to run the numbers to prove it, but I have a hunch that due to arbitrary/periodic ToC/EULA changes, there is a possibility that the tech industry has generated more legal contracts that no user has bothered to read or understand than the entire legal profession has honestly brokered (I.e. ensured informed consent between both parties) in its entire recorded history.

Caveat emptor be damned. There is something fundamentally wrong with a system that could manage something like that.

The problem is that it is a single crystal of silicon. To keep it atomically flat you cannot cut it at any angle. You must cut it across the axis the crystal grows in or the surface will be rough and the wafer will likely crack in half in a stiff breeze.

I suppose you could go for some more on-axis cuts, but the crystal planes are pretty restrictive on what you can do. You'd end up having super long and narrow pieces and such.

Completely off topic but it just occurred to me that I haven't seen the "X is killing the Y" rhetoric recently and I'm grateful for that.
Yea seems like people reach too much for larger "state management" via Redux/Mobx/etc. too quickly without thinking what that means instead of just using State updated via callbacks passed as props. Clearly Redux solves the times where doing that isn't really clear or gets complicated, but often times it sounds from Twitter + Conversations that everything is getting thrown in to Redux for no reason.
Nothing to do with "identity", the US is a big producer of fossil fuels and therefore has more economic incentive to use it, European countries or China have to buy it from other countries.
It's not clear that the results for Nell are "better", all three girls who recieve Runcible in its original form have outcomes as prescribed. They become independent of the Victorian mainstream. They aren't like the other girls. Nell founds a new group allied to the Victorians, Fiona is last seen among secretive London actors in some unspecified undertaking, and Elizabeth joins CryptNet, whose true purpose is anyone's guess.

The primers given to the Mouse Army are not just Runcible without a ractor. Hackworth reflexively, even unconsciously proposes something more, he says something about them being made culturally appropriate or something. Doctor X doesn't see this for the threat it really is. All those little girls are being set up by Hackworth to depend on an outside leader, whereas the girls who receive Runcible are completely independent. And the Mouse Army answer not to Doctor X or even to Hackworth but to Nell.
