>Think of the last person you know who left the company. Why did they leave?

I don't think you'll get an honest answer for this a lot of the time, often team members might not even directly know why someone was laid off

>When was your last vacation, and how long was it?

This is a bit tough too, it's very subjective. I personally like working, and while I encourage my employees to use all of their vacation time, I rarely do so myself (I spread my time around as individual days rather than large chunks).

Also depends on your audience. Parents will answer this much differently than individuals.

There are classes of nonprofits for which this is not true (the NFL, for instance, is one example of a nonprofit for which that is not true), sure, but most of the cases where this comes up about US nonprofits the focus is usually on specifically 501(c)3 charities for which this is specifically, by law, true, as they must be organized and operated for some combination of a specific enumerated list of purposes deemed socially desirable, which is the whole reason that not only are the organizations themselves tax exempt, but donations to them are tax deductible. Relevant to this conversation, that's absolutely the norm for nonprofit institutions of higher education.

One theory I've heard is that democracy, or the age of mass politics, was coincident with the age of mass warfare.

To see how, look at the English longbow. In it's own age it was a superweapon. It was both cheaper, could fire faster, and had better range than the crossbow. But yet, only the English ever used it. The reason why was because it was so cheap to make. But, for a person to develop the muscle mass and skill use it effectively took years of training, and once that training was in place, it could not be taken away. So that made any country that used the longbow vulnerable to peasant rebellions. So to use the longbow, England had to make the tradeoff that they had to make concessions to limited forms of democracy, or risk revolt. If your army uses crossbows, on the other hand, you can just take them away once the fighting is done.

Fast forward to Napoleonic France. Napoleon realized that liberte, egalite, and fraternite could be used as weapons. If your people are convinced that the state belongs to them, then you can arm them all. And that's exactly what France did- they created a people's army and ran roughshod over all the other countries of Europe until they eventually followed suit and also allowed forms of democracy in their own countries. They had to, or be conquered.

The age of mass democracy therefore coincides with the era of total warfare, for better or worse. We are allowed to participate in governance to the extent that our consent is required for the waging of war. But, that age is coming to an end. The development of nuclear weapons meant that there will never again be another war involving masses of infantry- so our consent is no longer required to run the country. The weapons can now be taken away, and so can democracy.

Well, that's one take anyway.
Amazon is much more willing to make deals to protect IP than Google or Microsoft have been (in my experience). Google will flat out admit that they will use your company data to improve their product offerings (which are available to your competitors) and will not acquiesce on that point.
> Even without any analysis code, just adding these calls can have a runtime overhead >30x. I would like to optimize this, but before that I need to find our where the overhead is coming from.

That thought entered my head immediately as soon as I noticed you were instrumenting every instruction.

> - that many calls are just inherently expensive, be it cross-language or not (possible solution: be more selective about when to insert calls to analysis hooks)

This is definitely true, and hard to get around. The wasm instructions will be compiled to machine instructions, and the calls will still be calls, and calls are expensive.

One possible approach to mitigate this cost might be to collect and batch calls into the hook functions. Basically your instrumentation would be a trace-dump of execution and data to some in-wasm memory, and periodically you call out to JS for analysis once the buffer fills up.

This should reduce the call overhead and replace it with a single write to a well known location.

Now, if your analysis functions expect to be able to peek at memory and get a consistent view of memory at the time of the instruction being analyzed, you'll need to do some special magic to re-compute the memory state at that time from the recorded trace, but that can be done on-demand when analysis requires, so 0 cost if the hooks are not present.

Please note that I'm not sure how well this would work exactly, but it seems promising.

> - Wasm <-> JavaScript calls are more expensive than Wasm <-> Wasm ones (possible solution: compile analyses to Wasm, or: hope that this gets optimized better by engines in the future)

It's getting optimized now. My impression is that the big cost here is marshalling wasm numbers into JS values. I don't know of a good way to avoid this aside from not calling into JS when you can avoid it (i.e. you know there are no analysis hooks attached to something).

I wonder if a simple runtime flag check within wasm, guarding the call-out, would significantly reduce the overhead cost.

> - the added instructions inhibit some wasm compiler optimization(s) (e.g., inlining is no longer performed because the function bodies are larger than some threshold)

This shouldn't be the case too much. Most of the heavyweight compiler opts happen before emission to wasm, including a good chunk of inlining. I'm not even sure if Odinmonkey (our Wasm impl) does any extra inlining on top of that - it might just expect the compiler to take care of that.

I'll get in touch. I think you'd get more confident answers on these from the direct WASM crowd. My answers are a bit speculative, and lack concrete details about the latest implementation status.
Are there any other alternatives?
it's data that asks to be investigated. There is no reason to query meaningless data. A query that tells you something you didn't know is infinitely more useful than a query that tells you what you already knew, and a dataset that encourages you to ask your own questions and craft your own queries is infinitely more effective than, say, an imaginary book catalog or some other nonsense that doesn't at all tempt the student to ask more questions of the data.

and besides: technology is a facet of society, it is not a purely rationalist act.
Thanks, Good replies ! Should remind myself to also think from other point of view.
Maybe it's because the process of buying a car sucks. I spec'd out a Shelby mustang last year and then called up a local dealer to start talking to them about it. They quoted me $40k ABOVE the price on fords website.

Put money down on a tesla instead, was exactly the same cost on the website, very happy.
All it takes is for a few states to change and have a critical mass of direct sales. NJ for example can’t insulate its market forever if neighboring states which are a short drive away offer consumers more options that they want.

I would argue that complex tools like this really have no place on the web. The benefits (available anywhere) are greatly outweighed by the cons (slow, no integration with your system, browser crap, ads, etc etc etc)

>Robin Ren - Tesla, Inc:

>Correct. Another thing I want to point out is that we are actually – since we opened the configurator to the general public in early July, we are seeing an increased demand coming from people who do not currently hold a reservation. I think that's something that we found super exciting, because these are the people who actually had no idea about Model 3 and they heard about Model 3 is available to order, many of them requested test drives and since early July, we have over 60,000 test drive requests in the U.S. alone and these people come into our stores, do the test drive, and they become super excited and they decide to order the car.

>So, we believe that the strong demand coming from especially the non-reservation orders is going to dramatically increase as we increase our test drive population. To give you an example, three weeks ago, we had only eight stores having test drive cars to Elon's point earlier. Now we have over 90 stores having test drive cars.

I'm not sure why you're being downvoted, since the i3 teardown is utterly fascinating.

A better comparison might be Toyota, though, when it comes to innovating on manufacturing. One of the things you'd really want to hear from Tesla is why a given part of the assembly line differs from established best practices, and that sort of explanation is something you never really hear from them. You do hear things like "oh, yeah, we just got rid of that stupid, fantastically expensive automatic conveyor belt system and replaced it with something simpler," and if you read the histories you know that Toyota and others retreated from systems similar to that in years past for similar reasons.
Unfortunately that is not enough to prevent murderous behavior. For example this angry gentleman https://www.youtube.com/watch?v=NBwk0tvLCxA

Fair enough. You raise a good point. I've only replaced one transmission ever (it was the Escalade). Most cars these days don't have drive train issues. I see your point. Maybe if they keep making cheap doorhandles these dealers will be fine.
I'm of two minds on this. One the one hand, nothing can replicate the college experience of:

- Living in a building with a bunch of other 18-22 year olds

- Living in a town that is mostly populated by 18-22 year olds

- Having to figure out how to take care of the laundry and dishes while having time to study and go to parties with said 18-22 year olds.

That being said, I'm currently doing YCs startup school, which is run very similarly to the large lectures I had in college. There is a main weekly lecture or two that is viewable online, and then there is a small group discussion with 15 or so others, led by a "TA". The discussion happens online but is live at a scheduled time (conveniently for me at 7pm).

As a 41 year old with kids, this system has a lot of advantages for me. I can watch the lectures at night after they go to bed, I can watch them in double speed so that I can done quicker and my mind doesn't get bored and wander, and I can do the discussion section from pretty much anywhere with internet.

So I think overall this system is better for me now, but if I were 18, I don't think I'd prefer it.
Luxury dorms? Which schools have that?
You're conflating electric cars and self-driving in a big way.
Issues with luxury cars is a different thing than maintenance. If you have air suspension on your car luxury car, it's not going to last the life of the car. My 10-year-old Lexus still gets frequent recalls like airbags, melting dash and other things. There are lots of wear items on cars that affect both EV and gas cars like shocks and brakes.

It is also possible that this family did not choose to have a cook, which is also not uncommon. Especially if they are of certain cultural groups, they have strict rules on such things.

regardless, you have a good point. its the choice they made and it is impressive to pull this off

> I'll often give a few toots before approaching an intersection to increase the chance that I am seen.

Are you also stopping at the intersection?
That's easy to say from our position, but I'd bet that the person responsible had a pretty good idea what would happen if they reported it.

At my current machine shop, I'd have a half dozen people documenting what happened, helping to design, implement, and rush out the repaired part, adjusting customer expectations, and making sure that the process that allowed me to make the mistake is fixed so that others repeat it.

In my previous job, it depended on the day. Sometimes you'd get called into the boss' office and cussed at for a while with no consequences, sometimes you'd get something capricious like confiscating the offenders' drill bits and requiring check-out for each hole from the foreman's office for a week. (It only lasted 3 days, but that literally happened.) Sometimes the boss was having a really bad day with customers or vendors he couldn't punish, and you could have a half dozen guys bodging a repair out of the boss' view and keeping him distracted. Or fired on the spot, if it didn't work. I lasted 5 years and 37 hires and fires at that 20-man shop, should have left so much sooner.

The official story is:

> It is a technological error by a specialist. It was done by a human hand -- there are traces of a drill sliding along the surface. - http://tass.com/science/1019791

Drills should not be sliding along the surface of a part. You locate the hole by marking with calipers from a known location and hit the intersection with a punch. Especially in curvy aluminum aerospace work. And there's certainly little opportunity for anyone to go get some glue, install it, wait for it to cure, and paint/cover it up without inspection. I am surprised, though, that they didn't just weld in some filler and grind it smooth.

I suspect that NASA and some of their suppliers are nominally more like the former but practically there's still some risk to admitting error, and that Roscosmos/Energia is closer to the latter.
