> which means you would have to plant 1T + X0B extra to cover the dead loss

It depends if the dead trees are in groups that leave large gaps in coverage or random deaths (Alopecia versus thinning).

Also surely the actual number of trees is almost irrelevant - the important factors are: carbon capture per acre per year, and risks of carbon release (fire, conversion back to farmland, milling etc).

There was nothing "Boeing" in Chicago at the time. The only thing relevant there in Chicago was United Airlines. They moved top executives physically and culturally away from where everything was being done.

In my opinion, that made the whole company abstract to the executives.
The usual fare of Dongle Incompatibility, we have a Dell USB-C Dongle that won't provide display outputs to anything that's not a specific Latitude Model, we have quite a few HP Notebooks that won't properly charge with standard USB-C Chargers (even Apple ones), then there's the USB-C Audio Adaptor issue where some phones output analog audio via USB-C and others need an active adaptor with a DAC, which look physically identical...

The Standard, if you fully embrace it, is a mess.
> We can try hard and do everything right and still something can go wrong.

Except they didn't do that. They did many things wrong, and it sounds like what they tried hard to do was cut costs, rush to production, and get a favorable regulatory/certification outcome via the cheapest route possible.

I miss the IBM XT & AT keyboards from when I started working programming in the 80s. That was a keyboard that you could take into battle.

Even the Selectric typewriters in high school had lighter keys than those things, but those were the gold standard for computer keys back in the day. Even if the buckling springs made your neighbors deaf.

Yeah, I like to beat on the keys a bit. My 2011 MBP keys feel OK, but I really hate the feel of the newer Mac keys.

> All Tesla needs to do is build out a similar Supercharger infrastructure in other big cities like we have in Bay Area and Los Angeles

I haven't looked in a while, so I checked out the Supercharger map for New York, DC, Chicago and Dallas, and was pretty surprised at how many superchargers are available already, with even more on the way.
I watched both. I know it's not comparable, but it seems plenty strong. In the case of the video, I'd guess if you'd double the contact surface, you could easily hang a coat on it. My question is, how long would the join last.
The i3 may be a good car for you, but it's not an alternative to a person considering a 3 or 5 series. That's the miss. While the car may be great, it's target market is small. In the US the i3 has a very small set of buyers and those buyers, if not BMW fans, will likely buy a Model 3 or Chevy Volt before the BMW. Both cars are more bang for the buck and can handle small families better/cheaper. The i3, with the range extender, basically turns the car into a hybrid - which exemplifies BMWs miss on what people want in an EV. If I'm going to buy an EV I don't want all the maintenance hassle of dealing with IC.

There have been many cars in history that have been popular beyond what top leadership has said. The failure of the i3 isn't that. It's a car that has a very small target market. If that was their goal, that's fine. But if they thought it was going to sell well BMW dropped the ball.

Regardless, it's good for you since you likely got a great deal.
The slides are a bit tricky to read without the rest of the accompanying talk. I couldn’t find a video with the brief search I had.

One thing the talk touches on is that writing a Lisp (cross-)compiler in Lisp is hard. The slides suggest a few reasons and here are some more.

In CL much of the compilation process requires evaluating CL code. It seems that you are therefore fortunate in using CL: you can just take the code and eval it. But this doesn’t work because (wanting to be portable and supportive of optimising compilers) many objects in CL can’t be inspected. For example the following is valid code:

(funcall #.(lambda (x) (1+ x)) 5)

In the code above one constructs a closure at read time, puts it into the ast and the compiler must take this call to an opaque host-platform closure (which evaluates to itself) and somehow marshal it into something for the target platform.

Similarly one can do the following:

(defmacro counter (name reset)
(let* ((i 0)
(incr (lambda () (incf i)))
(res (lambda () (prog1 i (setf i 0)))))
`(progn
(defun ,reset () (funcall ,res))
(defun ,name () (funcall ,incr)))))

So to write a CL cross-compiler one must first implement a CL interpreter and this interpreter must have objects with enough useful state that one can correctly marshal closures from the interpreter into compiled objects in the target system, even when those closures close over shared values.

One way to reduce this pain is to restrict the compiler to only compiling a subset of the language, and then requiring that the compiler is written in that subset. One may only compile more complicated programs when the host and target are the same instance of Lisp.

However the “easily compiled portable subset” is probably too small and you will end up with either a long bootstrapping process of increasingly useful compilers or having to implement a lot of emulation of your target platform. An example in the slides is that the result of (byte ...) is implementation defined so you can’t just use the value from the host implementation. Another example is floats. In CL there are 4 float types which are allowed to be equal to one another in certain ways (typical modern implementations have 2 32-bit and 2 64-bit; others might have some being decimal or packed into 63 bits), so one cannot rely on the host’s floats behaving a certain way, so one instead has to emulate the target platform’s float implementation to get reliably portable results. Then again, maybe it is possible (but perhaps a bit painful) to write the compiler without using any floats.

Another bootstrapping difficultly in CL is it’s object system which just makes everything harder, especially if one wants to use objects for lots of the implementation-specific types.

SBCL goes for writing the compiler in a subset of CL and the result is indeed sanely bootstrapable. Other implementations typically require eval and some runtime written in eg C and a slow process of evaluating the improving compiler on itself to bootstrap the compiler. This is easier at first but can lead to difficulties (some of which are described in the talk).
> Trying to vilify people and attempting to create an environment to produce massive punitive damages and lawsuits, or to bring political pressure to change staffing decisions dramatically decreases safety. The FAA has spent almost a hundred years building up an environment of cooperation with a shared responsibility to understand failures and enable the changing of the entire aviation industry whenever necessary to promote safety. This has been fabulously successful.

346 dead passengers is definitely not successful or acceptable. You think the rating/MCAS problem doesn't merit further investigation?
This is a great comment. Engineering is about cost cutting. Everything is a trade off performance, safety, efficiency, and cost.
> Why would it be in the union's interest to "divert blame from engineers"?

I don't know how it is in other places, but in the U.S. every unionized employee has to pay a fee to the union for the benefits it provides them. These benefits may include protection from corporate leaders if they try to fire you (see also: police officers, tenured teachers).

> Does it benefit financially from it?

Not directly, but there are a lot of employees who would be upset at the union if they paid their dues and still got fired anyways. Other employees would see this and be more hesitant at supporting the union in the future.

Alternatively, if there's a possibility that a lot of employees (>100) can be fired as a result of the fallout from this mess, that's >100 union fees that can no longer be collected.

> Do their members somehow benefit from it?

See protection described above. Note that, for some reason, some American unions believe in protecting their employees even if they deserve to be fired. I think this is where the politicization claims come in. By supporting this union leader you are supporting no accountability for engineers or managers who maybe should be fired. Or so the argument goes, I don't really agree with that line of thinking but it's understandable why people would see it this way, especially given the line between police unions and police brutality.

> Are you saying that Boeing wants to blame their Engineers and this is now a fight between Boeing and it's employees?

Honestly? Kind of. I mean, I'm not Boeing, but they certainly seem to be trying to paint this situation as a technical issue rather than a political/financial one. They sold a separate upgrade to the plane that provided two sensors instead of one, which could have fixed the MCAS problems. Why didn't the original plane just come with two sensors? Etc...

I'm actually interested in your perspective now. How are unions seen in your culture? Are these problems of unions protecting bad employees present in your country, or is it an American thing?
Is it really only fifty years? I would have guessed a couple hundred at least. Climate change is really a time problem. Given hundreds of years we'll be off carbon based economies purely for economic reasons. In fact I think that will largely be true in less than a century. So anything like this that buys us time may actually be all it takes.

But how about stopping deforestation? That seems like it would be more effective - pay developing countries based on maintaining their forested areas, policed using satellite data. I think we should also focus on planting trees and basically every other mitigation we can at the same time - doing one thing doesn't preclude others.

This is being done with some success in the rain forests of one of those deforestation happy palm oil producers, Indonesia.

My friend made it slightly under a year at Boeing after working for another airline as a maintenance mechanic. The level of quality control at Boeing was so abysmal he quit to work on busses, paying all $20k in relocation back to Boeing.

He takes pride in the quality of his work and adherence to the rules, but Boeing's managers let him know that reporting unwired bolts & incorrectly installed hardware per policy was something they did not do. Very sketchy, not something anyone wants to be signing off on as personally liable!

The management loves to circlejerk about the "Boeing process", but lots of shit is slipping through these days that would have been unacceptable (and firable) only 2 decades ago.

> Cost savings is always the root cause of every engineering failure, so long as you have the benefit of hindsight. I mean once you know what the problem is you can spend money to fix it, and they should have spent that money right off the bat, right?

I once heard it said that any reasonably smart person can build a bridge that doesn't collapse. It takes an engineer to build a bridge that just barely doesn't collapse, by an acceptable safety margin that still provides economy. So yes; any unforeseen failure exists because of that tradeoff.

The counterexample you name, the Space Shuttle, is just a series of fundamental mistakes compounded together--a boondoggle machine designed for a dozen different mission profiles, most of which never happened, and introduced serious regressions in survivability and launch escape compared to Apollo.
Worse, BMW thought they were in a comfortable position to exploit their customer base for money -- cutting back on their maintenance program, warranties, etc. and banking on people to not care.

If anything, BMW was driving people away from themselves faster than customers were already fleeing to e.g. Tesla or, more recently, Audi (e-tron), Jag (i-pace) and Mercedes (EQC) for electrics.

I have no idea how you could possibly think I'm saying it shouldn't be investigated. I also don't understand how you could think that a union representative complaining about the company using non-union workers is the same as investigating the problem?

Investigating, understanding, and changing regulations and future policies and behavior is what we need. A witch hunt with a bunch of vested interests trying to benefit financially and find a scapegoat is not what we need.

I am abundantly aware of the skills of most people. I even addressed exactly what you said in my response numerous times. I specifically said you can pay someone to host your site using site builders, templates, etc. None of that prevents someone from hosting their own site. You seem to be conflating hosting your own site from building a site from scratch. Chances are if someone doesn't have the ability to even pay someone to host their site, they aren't the target for this conversation and your point is essential moot.

I do. Going bankrupt means the shareholders who benefited from this lose their shirt, the company goes into Chapter 11, and the market learns that airplane companies exist to make airplanes that don't fall out of the sky.

It's very difficult to compare like-for-like, because we have different laws and compile crime statistics differently.

The intentional homicide rate is substantially lower in the UK (1.2 vs 5.35 per 100,000), as is our rate of killings by law enforcement (0.2 vs 30.4 per 10,000,000). The UK may have slightly more property crime (12.2% vs 10% of population victimised), but it's not clear if that comparison is statistically valid.

They match faces out of a crowd for criminals, but to be a criminal you have to have committed a specific crime... usually that means a single person. For any one crime, they are looking for a single person and that's worst case for false positive recognition. For a large sample set 50k-1000k, they are lucky they don't match any one person to multiple criminals (birthday paradox) ... that would be obviously disqualifying.

I suppose it could be worse and they just take an aggregate face of all (accused?) criminals or for particular crimes (white collar?) and match against that... hey your skin was brown, or hey you didn't shave... you appear Male.

There are many reasons to be afraid about a private corporation from a country with little regulation providing a utility to areas with no other choice.

If Amazon was sponsoring this, that's one thing, but them owning the network raises red flags for me surrounding:
1) Privacy
2) The potential for anti competitive practices
3) Quality of service / expected lifetime of service

I simply don't trust Amazon (or any other large private company) to do anything else than look out for their bottom line when push comes to shove.

> Govt's hardly own telecom infra, it's all in private hands

I'm old enough to remember when Australia did: https://en.wikipedia.org/wiki/Telstra#Privatisation

Since Telstra was privatised, any impetus to upgrade Australia's struggling networks has gone out the window and when they do end up upgrading capacity, it is usually as part of a Government project. All in all, tax payers still foot the bill to improve utilities while a private company furthers their monopoly.
