In a dense urban area, the speed limit is generally not dictated by road design but by the simple physics interaction between a person made of meat and bones, and a multi-ton metal vehicle.

Follow distances in urban areas with low speeds are already really small. I don't think AVs would make them meaningfully tighter.

The 65C816 had full backwards compatibility with the 6502 and starts in emulation mode after a reset making it essentially identical to the 6502 until switched to native mode. Even in native.mode it retains a lot of backwards compatibility with the 6502.

> The problem with "professionals" is that they are not incentivized to help you fix root causes either.

That's a big accusation against a community of people without any corroborating evidence. Do you have anything to support your claim?
I would recommend "Graphics and Graphic Information Processing" by Bertin over La Semiologie simply because the latter reads more like a reference book where Bertin is extremely thorough. But GGIP gets straight to the point and can frame your thinking while going through Semiologie such that you won't lose your way.

Unfortunately GGIP is expensive so I would try to find it at your local library. (French copies are online).

>Cost cutting and aggressive timelines will always happen, and in a company as large as Boeing, someone will have made a comment like this about pretty much anything, so I have a really hard time telling if this is telling data or hindsight bias.

Considering you accept that it's 100% certain it'll be be said it seems to be pretty telling data. I know we all laugh that management automatically fudges the numbers out of engineering, but mayhaps in Boeing's case the MBA logic of doing so is running into the issue of physics not being amenable to change just because management wants an earlier delivery date.
The Rx concentrations are higher and generally cholecalciferol instead of ergocalciferol which is less absorbable and not as long-lasting.
It’s fine to try it out. What I’m casting doubt upon is the blood test of Vitamin D levels and whether low levels are even an indicator of a problem. In my case I had very very low blood levels of D and was prescribed supplements and sun exposure. Years later, I found out I actually have a form of sun allergy. As mentioned, YMMV.

Article: Your Timeline for Learning React
In Wells Fargo's case, even after clawbacks, John Stumpf and Carrie Tolstedt ended up tens of millions of dollars ahead.

The idea that clawbacks could be used seems to be a justification to keep executive pay at present levels. Even though executives who destroy their companies clearly are not worth what they are being paid.
Exactly.

I wouldn't start with the CPUID testing though.

It's more like "Why do you care about ISA features"? Usually because you are trying to choose how many code paths to support for runtime ISA-based dispatching, or how many binaries to build when you build multiple versions of a binary (which may include compile-time dispatching).

So for that planning process, you only care about a few clumps. Then your CPUID testing strategy should still test all the required extensions, for completeness, and fall back as usual. Or something like that.
Yeah, but wouldn't you end up as the stereotypical "mr. Nice Guy"?

Also, you have to be a little more specific. For example writing open source software could be considered "volunteer work", but is probably not what you meant.
I haven't planned mssql, mostly because the library which covers most sql dialects in golang currently supports just those 3(mysql, postgres, sqlite) .

Have you actually used it in production? I would love to try it but I'm hesitating in case it's still not ready for a more complicated project.
In a similar vein, I was always a little bummed that Ambient Devices or some competitor never got more traction in the market, and never got much cheaper.

I thought they’d gone out of business but they are still alive and kicking. Unfortunately most of their devices no longer look much like gauges. Most look like clocks.
TypeScript can come close to this, especially with the latest release with Assertion support. You make assertions about your code, and the downstream types are inferred based on your assertions. Thus, the runtime behavior of your code gives you progressively enhanced type-checking. If you do these assertions at the borders, your "correctness" is dependent on the strength of your runtime assertions.

A cross platform library loses its potency if it doesn't work cross platform.
I found Ruby a bit easier to read and much easier to learn than Python as a beginner. In fact, I'd say it's the most beginner-friendly language I've seen, especially with great resources like Chris Pine's Learn to Program.

If I had to rank learning difficulty I've found various languages, I'd say Ruby was the easiest one I've ever encountered. It's very consistent, everything is an object, it's flexible and you don't need to learn anywhere near all of it to become productive with it.

Python is fairly beginner-friendly too, but it's less consistent, significant whitespace leads to a certain class of mistakes that are maddening for a beginner and at least when I used it pip was nowhere near as nice to work with as gems and bundler.

Both are much easier than JavaScript or anything where you manage your own memory, though!

Honestly, yes. I let my brain interpret the headline, "shares Max problem" and this is exactly what I thought it meant, before I clicked through.

As a non-aviation technologist, I initially thought it would be more surprising if the headline meant any of the specific technical failures that I've come to understand (like MCAS) which I've heard about through the ELI-5 and above coverage of the issues plaguing 737-MAX.

The root problem is the culture of disregard throughout many levels of decision making in an organization, such as Boeing has apparently demonstrated; the lack of regard for engineering quality and craftsmanship.

Edit: OK, here is another thread that has also made the HN front page with perhaps a more direct or less questionable title:

Platpick – B2B marketplace for outsource services
Immediately before Google were search engines like AltaVista https://en.wikipedia.org/wiki/AltaVista (1995) and Lycos https://en.wikipedia.org/wiki/Lycos (1994) which were not directories like Yahoo. Google won by not being cluttered with non-search web portal clutter, and by the effectiveness of PageRank, and because by the late 1990s the web was too big to be indexed by a manually curated directory.

You know, this is a great idea. I've been writing slide decks since the late 80's and having a template to think about the problem first is really useful. Can't believe this never occurred to me. Thanks! I just pulled down your tech_design template and I'm going to use it this week.

Challenger did not explode.

The key events of the disaster took place over about three seconds.

A leak of high-temperature gas in the right solid rocket booster damaged the external stack of solid rocket boosters and external fuel tank.

The damage to the external tank caused it to come apart, and resulted in a fireball from the released liquid oxygen and hydrogen. The solid rocket boosters broke free of their mountings as the disaster unfolded.

The Challenger orbiter momentarily survived both the fireball and external tank failure. But those events made it impossible to keep the orbiter correctly oriented.

The loss of proper orientation while travelling ~1000mph meant Challenger was hit with very high stress forces, far beyond anything it was designed to survive, and swiftly broke apart.

Shortly afterward, the Range Safety Officer remotely detonated both solid rocket boosters, which had survived the disaster mostly intact and were careening out of control.

If tickets weren't cheap, people would just be flying less, and it would be relegated to things like business trips and what not. Low prices should never be the end goal at the expense of things like safety. However, capitalism says otherwise.

PMs are ideally senior engineers who've learned how to communicate with customers, salespeople, and clients (both senior management and end-users).

Unfortuantely, many companies/projects/teams don't budget properly for the PM role and you end up with MBAs or other non-technical business folk, who are often 1/3 to 1/2 the price of good technical PMs.

Yes, they try to imply that the 'Max problem' in the headline is the MCAS. We can conclude that with some certainty, because the headline is quite awkwardly written, to fit the quote in there. (However, it is of course entirely correct as written.)

Machine Learning Needs a Langlands Programme
I've lived all over the UK. I think Cardiff was the hardest to "slot into" - an English accent in Wales can prompt some interesting interactions ;) Though small-town England is also a nightmare of "if you didn't grow up here, fuck off".

Social class in the UK is all about where you were educated, it has nothing to do with your income (same for Australia, but apparently not the USA, though I think that's changing). Your accent, your manners, whether you call it "dinner" or "tea", whether you go to the toilet, the lavatory or the bathroom. If you actually care about social class, these are the things that matter. Income doesn't.

But attitude is the big one. You can fit in and make friends anywhere with an open attitude. People are people. Friendships can easily overcome class and income differences if there's mutual respect, empathy, and a desire to be friends.
I've read this a few times. Agree it's good. But....its from 1994 and it really doesnt feel research based. Its also highly counterintuitive in its approach. And at least for me it took a few weeks to work through the first time due to the required work.

His work is a great resource but glancing at this thread theres a few other things that might have higher ROI. At the same time, if you're not substituting with something else, this book is world better than not reading anything.
It sounds like you think adding a conversion at the start is difficult and cumbersome, but it isn't if you use a good serialization library. E.g. with the Rust library serde, you just define the shape you expect your JSON data to have and plop a #[derive(Deserialize)] on it. Boom, fully failsafe JSON deserialization into the type.
It isn't PR speak when you just tell the truth in an email and don't let management bully you into not saying what needs to be said to prop up their take on it.

It can end up a bit dangerous, because they'll be more than happy to drag you through the mud in court to try to discredit you, but a lot of people kinda expect that anyway.

I’m glad that this your view, thanks for the clarification. You did literally write that ad tech is on the “opposite end of meaningful work spectrum”, and we both agree that space exploration is certainly on the positive end of it. This literally mirrors the definition of black and white (ends of the color spectrum).

I am sure you are right in that there areas that would deserve more talent given their impact. Care to elaborate which ones stand out in your mind? (Besides space exploration?)

> Screens are also less likely to break than mechanically moving gauges

What? If you buy a 30 year old car, the gauges are most likely still intact, and original. If you have an older house, things like the water gauges (or even regular clock gauges) are also decades old. I want to see the screen that will work for > 20 years in a constantly moving and vibrating environment, under massive temperature changes, without any additional care or repairs or replacement.

Take passenger information displays in public transit. Not until a few years ago, it was still common that the head signs in trains, buses or subways where mechanical. It was often just a paper roll [0] that was adjusted to display the correct destination, or even just a plate that was changed by the conductor [1]. Things like car numbers or seat reservations were displayed by simple paper signs. Fast-forward to the 90ies, where at least in Europe, they began to replace these things by LCDs. After a few years, it was normal to see trains with broken head signs, broken car numbers, and broken reservation systems [2]. Fast-forward to today, where it is now en vogue to use full-fledged displays everywhere. The result (at least in the towns I use public transportation) are regularly broken displays [3] [4] [5] that even when they work, often offer no advantage over LCD or LED or even mechanical display from a passenger perspective. They just look more modern. Add to this that the display software is mostly some variant of Windows with a poorly built and designed web application running on it.

Think of all the people, all the knowledge, all the hours, all the resources and all the energy required to build and run a full-fledged high-resolution display, an operating system, the web application and a central server in the vehicle running those displays - all to replace a simple roll of paper with a less reliable solution! As computer scientists and software developers, this is what pays us - but as soon as the rest of the society realizes what is going on, I fear that there will a massive backlash.

There is no one solution that is meant to not fail.

It is layers of redundancy. If one fails, the car continues to operate normally. If all are operating at peak, the car is near perfect. If multiple fail, it operates with somewhat degraded performance, but still markedly better than a human.

There is no reason for a supplier of hybrid seeds to have this sort of contract, as the hybrid would not breed true.

As for patents: while patents in general have dubious applications, plant patents in particular are not dubious at all. Patents are absolutely essential here, because the cost of manufacturing is extremely low (just grow the plant!) If plants that breed true could not be patented then developing them would be worthless. The cost of development could not be recouped after the first sale.
