The rockets for long haul flight is still a goal of SpaceX's. They are pursuing that as a kind of secondary market (which would have a LOT more demand than Mars missions) for their Mars rocket. In fact, they're more serious about that now than ever.

Hyperloop is making progress. It wasn't a priority for Musk; he didn't start a Hyperloop company, but open-sourced the idea and let others run with it. Those companies have kind of petered out for the most part. He did also start a student competition for Hyperloop, which IS continuing. There's a mile-long prototype vacuum tube outside SpaceX's headquarters where students tested pods going hundreds of miles per hour for several years (including 2019). He is now having a 10 kilometer long tube (with a turn) built to continue the competition and test speeds comparable to the original concept. He did start The Boring Company to try to address one of the main problems with Hyperloop (the extreme cost of boring tunnels), and that IS making progress. They're on-track (heh) for completion of tunnels in May for a mass transit system using pods (but at atmospheric pressure) based on stretched Tesla vehicles that will serve the Las Vegas convention center. Currently has dug about 3000ft of the first tunnel which is to be a bit more than a mile long.

The cave bit was embarrassing to Musk, he made some gross mistakes, and while the submersible folk were definitely trying to help (like NASA had developed capsules to rescue trapped miners in past disasters), the feedback of crazy between Musk and the media was more a liability than a help. He lost a lot of credibility with the name-calling, even though I definitely think he had been trying to help.

Musk is chief engineer at SpaceX, so he does similar systems engineering work as you'd expect for someone in his position. If you talk to people who have worked with him, they will tell you he has a good understanding and a deep technical involvement in both companies (especially SpaceX). Although that's hardly unique. I think the main strength is pursuing goals that are both important and challenging and empowering his employees to execute quickly on these challenges (and part of the reason he can empower them to act quickly is because he has enough technology knowledge to make command decisions on key technical questions which otherwise could end up in "analysis by paralysis" or even worse, continuing down a technical dead end just due to organizational inertia).

>The scientists went on to try 300 configurations of rain, pollution, and heat flows—something they can do as gods of their own digital earth—before matching the model to history.

Having worked with complex geologic (not climate) models in the past, this is the part that gives me pause. The scientists have set out as a first principle to find warming and then are working backwards and, ostensibly, everything is legitimate because model results are calibrated to previous real data.

But here's the problem. When you have complex, chaotic models with hundreds of freely tweekable parameters, it's fairly easy to fit data and simultaneously get any future prediction you (or your bias) want. Even when individually each variable is within a reasonable range.

We arguably have proof of this happening - climate models have been consistently overpredicting dT for what, 10 years now? There is an institutional problem with climate science, in that there is no real penalty for being wrong, and in fact the more aggressive results probably get the most attention. Because the modeling is so far removed from any sort of experimental or observational data collection, I think the field is dangerously susceptible to institutional bias.
Inflation can spiral out of control and be very difficult to control if it does.

It's a tiger that you don't want to let out of the cage.
Pardon the pedantry, but "-the- models have done a great job of predicting reality" seems like a bit of an overly strong statement. The link you give and the original article seem to be comparing a completely different set of models, and the main article even says there are "dozens still left to report....".

Many years of experience tell me that you're going down the futile path of getting a tiger to change its stripes. As more and more devs get minted, prepare for codebases (and libraries) to get a LOT more gnarly. Even so, it's a good thing to lower barriers of entry and we can be discerning about where we get our code.
Whenever this happens (juniors questioning decisions which have a lot of context requirements that they don't have OR VPs from other departments questioning something core to my world) I look at it as a problem with myself not presenting the case in a convincing manner.

The junior engineer is probably trying desperately hard to apply something he read in a book somewhere or hacker new the previous day. You will have to invest time to tease out the differences, ensure they feel listened to.

The VP is probably trying to either catch you off foot to make a point he is itching to make to belong OR is trying to ensure you know what you are doing. Good senior folk build knowledge like a tree: Some branches are full and dense, some are bare - but overall they make up the whole tree. The bare branches here would be your core world and once they get a sense of you knowing what you're talking about, usually you should be fine. Bonus if you add to their knowledge without being defensive.

RE time taken for this: I look at it as future investments. If it is a junior dev in my team OR a VP who can actually impact my day to day life, it is worth building that relationship where they get to a trusting spot. If it is a random person, I might just agree / nod my head and move on to wrap up the conversation.

And yes there are bad actors everywhere - tough luck if it is the VP (happens), hopefully you can manage out the junior fella.

A couple of people have mentioned Evernote, which is a great product, and a great service, with a great plugin for Chromium-based browsers (even Edgium!). However, I love me some markdown, so I've started using Boostnote for my actual "thought" notes. I like it quite a bit, and I've found a few tools that help me "clip" articles from the web and turn them into markdown. So far, I prefer `clean-mark` (https://github.com/croqaz/clean-mark#readme), because it has more consistent conversion and better meta-data generation, but I've also used `hget` (https://github.com/bevacqua/hget), which, in my experience, is not as robust but sometimes catches things that `clean-mark` misses.

> Anyone who expects a database to always have records and that the absence of a record is an "exception" has a very strange way of thinking.

This isn't something you can make universal statements about, because it depends on context.

If the program knows it just put or saw the record there, is it strange to assume it's still there? If the program completely controls the database and something else in it implies the record is there, is it still strange to assume?

Sometimes broken assumptions can only signify that something has gone very wrong, and it's not worth handling them at a fine-grained level. That leads to the "gotta catch em all" antipattern the article mentions.
The post is in fact about the argument, rightfully pointing out it is essentially high class spam.
Usually, fear. People hoard cash when they're afraid of a crash. When a crash happens, money becomes more valuable, so they can buy things more cheaply. People who anticipate a crash risk provoking one by removing money from the supply.

So central banks try to counter that: "Your money will be worth less in the future, so spend it now. Or make an investment that will produce returns greater than the rate of inflation." So they spend their money, creating demand, and jobs materialize (hopefully) to fill that demand.

For the last decade-plus we've had a combination of anticipation of disaster, and banks flooding the system with cash to assuage that fear. That's like pressing both the accelerator and the brake as hard as you can -- you don't go anywhere until suddenly something gives, and then the entire thing goes to hell in a handbasket right quick.

When? If I knew that, I'd be rich. The general advice is that the market can remain irrational longer than you can remain solvent.

Really well put together- I learned several more things about PG text searching from this.

From my personal experience working with dozens of California tech companies of varying sizes, I'd say around 80% of the time I see ElasticSearch being used when the product could have just used their existing PG cluster (and existing team experience). I.e. so many companies pick up ElasticSearch only because they lack of full-text search capability awareness of PG. Of course, ES does have its advantages, but I feel it's in very specific use-cases.
FL300 is very cold and very dry, and bears almost none of the "atmospheric water". Your estimation of impact is not correct. This is not a linear system.

Differential Privacy is a mathematical property. Here is the precise definition:

https://en.wikipedia.org/wiki/Differential_privacy#Definitio...

One way to phrase it intuitively is "the probability of any particular output from two databases that differ by one element is almost the same". The bound on "almost" is captured by the privacy parameter ε.

One of the smoking guns that this algorithm is not differentially private is that the code doesn't import `random` anywhere! A differentially private algorithm is always going to be stochastic.

OK fine but there was _some_ non trivial technology behind the system that won the Jeopardy game.

Precisely. But don’t take my word for it. If you’re into a light introduction, consider watching Sabine Hossenfelder’s interview of Tim Palmer (a theoretical physicist’s interview of a leading climatologist is a thing of beauty in its own right).

I don’t mean “I thought I was dying”. I mean that I actually was dying and the regular world turned off and another world turned on. At first it was dark and silent; no perception of any kind, absolutely nothing. I could talk but there was no echo, and then I slowly realized that I didn’t have to breathe, and then I began to panic and scream because I realized what was happening although I didn’t know why. Then transported to dream state, long vision quest kind of stuff that I’m still trying to process (10 years). Then back into nothing world, but this time it’s tearing and burning deep throughout my body, a seemingly impossible level of physical pain; mental anguish or fear of death not even registering anymore. Then I came back to consciousness in and out for a while during the rescue and eventually back to (mostly) normal.

The mind’s potential for suffering is immense. The scale doesn’t go nearly as far in the other direction. I cannot imagine any possible pleasure within many orders of magnitude. I can see how this would stop addictions by eliminating the sense of all pleasure or minor discomfort. Its possible that this was part of ego dissolution and I just didn’t come completely to the point of acceptance of the pain, but I think about it a lot, and fully expect an eternity of that when I die.
