For equality, yes, Theta works! But I care not just about equality but about comparison. In particular, it would be nice if the "natural" ordering on A(f) had the property that

A(f) <= A(g) iff f is O(g)

Theta(g) is a set, and the most natural ordering on sets is subsetting/inclusion. However, Theta(x) is not a subset of Theta(x^2), even though x is O(x^2)! So the natural ordering on sets doesn't do what I want.

It might be possible to define an ordering on Theta-classes that does what I want, though.

Edit: I just saw your comment about O. I think O might just work! So instead of remembering big-O, Theta, and Omega, I can just use

O(f) <= O(g) for f is O(g)
O(f) = O(g) for f is Theta(g)
O(f) >= O(g) for f is Omega(g)

Is that true?

(I think small-o might be slightly more complicated, unfortunately. It has a more unusual definition: https://en.wikipedia.org/wiki/Big_O_notation#Little-o_notati...)
It's weird, because the person said "another one of those..." The Talia Jane article came to mind but I'm quite sure there aren't others. Seems kind of weird to imply this happens all the time when its happened exactly once.

I'm still not quite following. Is the "perimeter" here the sum of the lengths of projections of the edges, then how is that different from "the sum of its projections"?

Anyway if you define "perimeter" that way then for the outer box the "perimeter" is in fact 4 * (a+b+c), where a, b, c are the dimensions of the box. I also agree that for the inner box the "perimeter" is at least 4 * (a'+b'+c'), by the triangle inequality.

What is not at all clear to me is why the "perimeter" of the inner box is no larger than the "perimeter" of the outer box in this setup. You say it's easy to check, but it doesn't seem very obvious to me.

He doesn't get to "keep every penny". There is such a thing as personal income tax, and in Canada is going to be over 50%.

Hopefully, the deal was structured with some stock, or paid to a corporate entity. Because if he received a cheque made out for $575M, most of that money went to tax. If it was made out to his personal corporation, he'd just have to pay corporate tax on it, which is about half as much. But would still be over $100M.
Saw the clickbait-y headline and thought, "ok, so how did he escape paying taxes? some clever trick"?

I assume the tax on the deal was hefty so while nice payout it certainly isn't "every penny".

The following is taken from an article published on June 2016...

http://lppfusion.com/git-12-z-pinch-achieves-6-joule-fusion-...

"GIT-12 Z-Pinch Achieves 6 Joule Fusion Output with Deuterium Fuel"

"Z-pinch devices are closely related to plasma focus devices in that they also use the currents through the plasma itself, not external magnets, to produce the strong magnetic forces that confine hot plasma. In a z-pinch, however, the current flows between two electrodes in a line, rather than the plasma focus’s concentric electrodes. At the Prague conference, Russian and Eastern European physicists announced new experiments with the powerful GIT-12 z-pinch. They used a configuration in which the plasma was arranged in two concentric rings, puffed into the gap between the electrodes right before the discharge. Nearly 6 J of fusion energy (producing 6×1012 neutrons) were released with a 3 MA current and 3 MJ of input energy to the device. Since only 500 kJ of energy was released from the capacitor bank prior to the pinch, the ratio of 1.2 J of fusion per 100 kJ of input rivaled or slightly surpassed the best results obtained in either plasma focus devices or tokamaks, both of which are close to 1 J per 100 KJ input."

The implication is that both Z-Pinch and DPF devices are close to tokamaks in terms of energy efficiency, based on the experiments performed to date. Do you disagree with this? If so, why?
Yep, the word "startup" has the same definition to me. It's more of a description of the culture than how new or scrappy the business is. I worked at a "startup" that had been around for 10 years, had no plans of exiting, and was sustainable, but had a very young staff, a keg in the kitchen, and pressured it's young developers to work late for shitty pizza.

I think some small businesses are jumping on the startup train so that they can attract kids right of college.

Not true, I don't think that is obvious at all. In fact, I think very highly of my boss. If I didn't, I would have left years ago. It's one of the things that makes the idea of leaving so difficult.

Great deck! In particular, for the incredible magic on slide 14, a debt of thanks is owed to John Levon[1] and to whomever has maintained that work and brought it forward.

On slide 28, the presentation asks "What is 'Speculative Tracing'?" It's unclear if that's a rhetorical question, but just to answer it here: speculative tracing is a DTrace facility that allows for data to be traced speculatively, and only committed to the trace buffer if and when some other (later) condition is met.[2] My original inspiration for this was a case that we had back in the day at Sun on the Performance and Application Engineering (PAE) team, when Yufei Zhu (now at Facebook) described a case she had in which one out of every 10,000 mmap()'s was failing with EINVAL -- and it was really tough to use DTrace when she was only interested in its output 0.01% of the time. For Yufei's (motivating) example, speculative tracing offered a way of capturing all of the necessary data on every mmap request, but only emitting that data when the entire operation was found to have failed. Speculative tracing is one of those you-don't-need-it-until-you-need-it features of DTrace (to which I would certainly add anonymous tracing) -- but when you need it, it's a lifesaver, and I have it used it as recently as last week to nail a particularly nasty bug that very much needed it.[3]

This is a situation where the resource (access) is scarce, and needs to be managed... I think local management is usually better, in this case I find it almost ironic that the cities are fighting for the same rights (freedom to make those choices separate from higher government) that the states are wanting.

In those locations poorly served, municipal choices make a lot of sense, it isn't about socialism/communism it's about pragmatic use in scarce conditions.
While I appreciate the good intentions behind this ethos, and the value it may contain, I gotta ask: what real good does this awareness accomplish? I can be as aware as I want of the vast extent to which the system from which I've reaped such rewards has crushed the life from others -- what of it? What good does it do them?
I think the fail states in Sierra's games were actually part of the fun. Just because of the variety and how tongue-in-cheek many of them were. It was amusing and sort of an easter egg hunt to find all the ways you could die.

Yeah, that sort of thing instilled a life-long habit of constantly saving my progress and having saves that go back many hours. I specifically blame King's Quest II for that. There was a bridge that you could only cross a handful of times and then it collapsed. If it collapsed too early in the game, you are screwed and need a save prior to crossing it unnecessarily.

Looks really interesting! Thank you and congratulations on the release.

I have to make one observation that I was wondering if anyone else also makes and please don't take offence at this, every time I see a new piece of software on HN, if I find it looks interesting I click (tap) on the Git(Hub|Lab) link and find myself (almost crossing my fingers) saying 'please don't be node!, please don't be node!, please don't see npm in the install instructions!'.

There's clearly a lot of highly creative people out there that can see problems / needs but that have probably come more from a design background rather than a programming / engineering background that may not see the same issues with the node / JavaScript ecosystem that programmers or operational engineers may.

I think that it's clear that designers and creative types value things that the JavaScript ecosystem has to offer but as an engineer of bother engineers and software delivery - after significant experience node, JavaScript and npm are each things I avoid at all costs. The amount of performance, security, package management, standardisation, general hosting and deployment problems I've had, seen or worked with people on for this ecosystem is down right scary when given its current prevalence.

Again, authors of this project, no offence intended towards you at all and I'm certain I'll get down voted for saying it but I just found this another case where I found myself saying out loud 'oh... javascript and npm, bugger, write that one off then.'

Their main point is not that Tesla cars are badly manufactured. But that they don't make repair manuals available, they don't sell replacement parts, they lock down access to the car's systems, don't give salvage titles, and that these cars will be very difficult and expensive to repair in the future.

False comparison. Your gas car also has specialized electronics, namely the ECU, the ABS system, the SRS system, which are all needed for the car to be operational. Good luck finding an aftermarket ECU for your car.

There's no more "only-for-this-car" equipment in an EV than in any other car; the main difference is that with so many models of gas cars made by each maker, they reuse a lot of parts between models, so there's economies of scale. In an EV future, the same would be true for EVs. You're not going to swap an axle from a Chevy into a Honda, or from a Honda Civic into a Honda Ridgeline, so even here it's limited. And you're not going to swap a door panel from a 2017 Civic into any other car at all, or from any other car into that one; those are only-for-this-car items; every car has those.
A car rental company could do that even better than a car manufacturer.
While I do appreciate preact, and have used it... it doesn't contain all the error detection and messaging that react proper does... that's where a lot of that much smaller initial load comes from. When you aren't having issues it's great... if you are, less so.

It really depends on your needs, you can get a very small app/module via preact, and I like it a lot. If you're building for a larger environment, or larger applications, you may be better off eating the extra 60-80k or so for React proper.

Ask HN: Best practices for supporting remote employees?
Hey HN,

I'm the lead programmer working for a small startup (20 employees now) that's beginning to staff up on customer support.

Our support folks have a great deal of power, most of which is accessed through a web app that we've created. We also have an extremely liberal work from home policy.

We've protected this application with IP whitelisting -- only IP addresses on the list can get to the admin site. Plus, each administrator has their own login with username/password authentication.

Maintaining the IP whitelist has become annoying as the number of employees has increased, so I've started to look at other options. It's also got me thinking about best practices with regards to remote workers. We don't have any kind of policy written down. So far we've just been playing it by ear.

So, on to my questions:

- What are the security issues that I should be thinking about with regards to remote employees?

- Would a VPN be a good replacement for IP whitelisting? (I'm a bit worried IT overhead of supporting that. And we don't have a separate IT support team or anything, just a small team of four programmers.)

- Do you have new employees fill out some kind of telecommute agreement, or agree to a telecommute policy? What's in that agreement/policy?

I'd also be interested in any of your experiences with telecommute policies in general, especially with regards to customer support teams.
You can do this very well without paying anything though? I just have my rss subscription email my kindle email and it worked perfectly?

>>Here is to hoping EU politicians fix the tax system and force companies to pay a meaningful tax in the countries where they sell their products.

They already did. The tax is VAT and recent changes on electronic services had exactly the goal you mentioned in mind.
It's just that the idea of income tax for companies is silly as it requires the tax authority to verify valuations of transactions (for brands, services etc.) and that will never be doable. The fixing would be to get rid of income tax for companies and substitute it with different taxes (like VAT for example).
I'd rather pay taxes to Apple, Tesla, and Google than the US government. At least they're competent.

Excerpt:
The US has peculiarities in its income tax code that create these incentives for companies to avoid repatriation. The last time those peculiarities were lifted was in 2004 when then-President Bush allowed a one-year repatriation tax break. Over $300 billion flowed back into the US. Discussions about repeating that tax break are stymied in the current administration. Estimates are that as much as $1 trillion in repatriation would potentially occur if the Congress and the White House could agree on this issue.

With the election approaching this is one issue on which Trump speaks eloquently.

That depends heavily on whether Apple received clarifications and information about the existing tax code, or whether they received special-case tax breaks that didn't apply to everyone. The latter might violate EU requirements.

Ha! I like it. US all of the sudden is defending Apple. Not because it loves Apple, but because it was hoping it would get its hands on those billions ... somehow.

EU here is basically saying, "ok Uncle Sam, fish or cut bait, do something. If not get out of the way, we'll take that money". So Uncle Sam is a bit upset at that, he doesn't like to be handled that way.

They will probably be various threats of sanctions from US and EU will buckle eventually. Maybe some scheme to divide the tax penalty between US and EU eventually.

I don't think we have to understand it well enough for AGI to interface with it because it will adapt to the inputs whether we fully understand them or not as I think we've already seen with hearing implants. We can utilize the brains extraordinary ability to find signal in noise without understanding how it does it.
