So my understanding following this:

* they designed mcas with a g sensor and aoa sensor and a max pitch, to fix a problem in a high speed test. They provide safety assessments based on having two sensors, limited pitch changes, and it only triggering in specific rare situations.

* they provided that to the FAA as justification no training was needed, and that there was no need to acknowledge the existence of the system. FAA agreed.

* After FAA approval they discovered that the aircraft didn’t work correctly at low speed either, so they made it activate at low speed as well. Because it activated at low speed a g sensor wasn’t possible (?) so it got removed. Now you only have a single (notoriously unreliable) AoA sensor controlling it. To compensate for poor aero they also needed to increase the amount of pitch needed. So the FAA approved MCAS with a 0.6 degree pitch limit, occurring at high speed, triggered by two independent sensors. Boeing then made the system trigger at low speed, off a single sensor, and increase pitch adjustment to 2.6 degrees.

* Boeing chose not to test what happened if the AoA sensor failed.

* Boeing continued to insist that pilots not be made to retrain, because of contract penalties with southwest. That meant they did not want to mention the existence of the system.

* there safety margins also included an assumption that pilots could respond to a problem in 3s. But when mcas triggered incorrectly they were given speed, stall, and altitude warnings. All of which distracted them from the non-functioning led that indicate activation of a system that Boeing did not tell the pilots existed.

* the standard way to recover from the flight control computer triggering to much pitch was to flip a switch on the stick. Boeing made MCAS override that command, so the standard recovery could not work.

* Boeing continued to claim the plane was airworthy and provided a work around for its hellbent desired to crash, which was to use the manual pitch wheel. Except MCAS was designed in such a way that as part of its crash into the ground logic it put so much stress on the system that it was not physically possible for a pilot to perform the workaround.

In all: more than 300 people are dead because Boeing rushed to make a plane to compete with another company, and then hid information about an overriding control system so that they wouldn’t have to retrain pilots, and that completely changed the parameters of that system after FAA approval such that none of their approved safety claims were remotely true.

All to make some money so executives could get their bonuses.

Every executive who pushed for those changes should be put in jail.
As I understand it, the frequency response of a tube power amp is influenced by the output transformer, and to a lesser extent by minor design parameters such as the value of coupling capacitors. To a very rough approximation, lower frequencies need more iron.

On top of this, the preamps in some historic amplifiers tend to have a decidedly non flat response curve when the "tone" knobs are centered.

> One person's consumption doesn't matter

Just like one car doesn't pollute...

How did we end up in this situation if it isn't an accumulation of individual actions?

Of course individual actions matter, not necessarily because of their direct impact but because of the snowball effect. Look at how green parties started 60 years ago, it was hippies and nut jobs, today they make 10-25% of votes in EU elections.
What is D&I?
Then how do you propose companies market their products/services? You want us all to go back to pre-90s era where advertising was controlled by few media conglomerates who favoured only the giant corporations? Today, a mom-and-pop store has as much an equal footing as a big-box store when it comes to advertising their products/services online.

Spammy articles should be dealt with the way spam is dealt with in email. Pruning is the way forward in my opinion. Consistent cleaning of the search results of spam and ensuring high quality results should be the priority. I don't understand why the tech crowd is so anti-advertising. I rather the tech crowd focuses on coming up with solutions to remove bad advertising methods rather than do away with advertising all together. The latter will just cause big job losses and the ones affected won't be the large corporations but small business that rely on these cost-effective advertising solutions.
The article makes many good points about Haskell including cons: "Very difficult learning curve. Let’s get real. Haskell is a very confusing programming language to get started in for common programming tasks."

I can't avoid the comparison in my mind that Haskell is like Latin, spoken by priests, a very nice language Latin is.
No it doesn't it has nothing to do with that. However, if you think an article should be a paragraph long then you probably didn't have anything worth creating the page for anyway.

Plenty of ecommerce sites ranks with very little text on their pages. What you are saying is just wrong.
A rule of thumb here. Companies with 20-30 employees can afford $75-125/hr contracting rates. And these smaller companies will take less time to sign contracts and start.
Man page: find the man page, search for terms you hope might be related to what you want, read through a lot of dense paragraphs to maybe find something relevant.

Google: just type in a quick description of your issue and get a stackoverflow post with an answer as the first result.

I don't get how anyone could prefer the man page.

Absolutely true. The pessimistic view of "closing doors" once you start a family prevents one from doing anything. There won't be ever the right moment of starting a family, so why don't just do it now. I did it during my PhD studies, finishing now with my great little family. My partner and me both work hard to get towards our personal goals. Sure, we live in a European country. We don't profit from a close family but from cheap public-money-funded child care. I absolutely can understand the feeling of loosing power (I suffered a lot personally too), but if I got the correct idea I would not wait a minute to start a buisness. Or do anything else wildly time consuming.
Papercrete[1] is an interesting material. It's a mix of (usually recycled) paper and concrete, so clearly using it wouldn't get rid of all of the pollution caused by concrete production, but it would help. It also can't be used as a concrete substitute in every situation, but it has some interesting properties like being a much better insulator than concrete, and being of very low cost.

this started to get interesting with VB4. Suddenly you could create COM servers which especially back then was really difficult to do in C++. VB6 was a really well rounded tool.
Sheesh! Do you care to share any more details? How dense of an area? How was it detected? If by "access point" you mean 2.4GHz, what was the actual problem?
I've been looking for a while for a copy of the original red Plivka/Pakin APL book (not the APL2 one, even tho APL2 is what i know best), and they're there now on amazon, under $10.

Now i can relive the arguments about whether Sharp, STSC or APL2 was best
I think we should improve our tools/planing/everything to support 20% more of us at a higher level of luxury..
No. In fact, the solar irradiance gets fairly low even by the time you reach Saturn, because the power propogates via an inverse square law. Near Earth, which is 1 Astronomical Unit (AU) away from the Sun, you get about 1000W/m^2. Around Saturn, which is about 10 AU away, irradiance will be down to 1000/10^2 = 10W/m^2. So 1% of what you get near Earth.
Is that a semantic argument - that low risk investments should be called something other than "venture capital"? What term would be best for that?
Note that VC does have a wide variety of risk profiles - with later stage usually being lower risk and earlier stage being higher.

Is this really the case? The timing parent is talking about is fractions of a cycle, maybe five orders of magnitude above audible frequencies.

How could you take advantage of exposed timing?
Yeah, I found 55 profiles/pngs. Tried ordering the profiles by the image # (from 2 to 56). Noticed the profile names are also a variation of two emojis, so tried looking into binary/morse, but nothing.

As the comment above implies, it seems like my approach was wrong and the answer is in one of the images I guess
You should have a go at F#. OCaml-like syntax, strong type system, and like Clojure sits in a large reusable ecosystem (in this case .net). Cross platform in dotnet core too.

I actually wasn't sure what a better term was. Tor site? Onion site? Is "dark web" ambiguous; can it refer to other technologies?
Web browsers used to cost money. I vaguely remember getting a boxed copy of IE from an MS rep that came to my school as a kid. ISPs started bundling Netscape if I remember right, then MS started giving IE away for free with the OS. In the end we got Firefox, so I'm glad for that, but we can blame the browser wars in part for the unwillingness to pay for agent software.

those three are clear - but the next most complicated ones (Reader and Writer) are head-scratchers, and any beyond that are just completely opaque. And that’s not even considering monad transformers!
The article specifically refers to carbon dioxide as pollution, which was disagreed with by the parent poster. Carbon dioxide is semantically referred to both as pollution and non-pollution, and I was pointing out the contrast.

Your comment, on the other hand, is purely non-substantive.

Try duckduckgo for a few days. I now switched since a week and I seriously noted the decreased quality of results, compared to Google. It's not the design which makes Google unique, it is still the quality of results, despite its 2019.

Having said that, I know there a few anonymizing services which basically tunnel your query to Google and display it on their old fashioned page. That maybe something for you if you feel you need Google-Quality of results.
The nice thing about these old tube amps is that the schematics are freely available (Fender ships a copy of the schematic with their amps). There are also quite simple in term of number of components.

However, there are dangerous, with 400/500V DC for the tubes. Definitely not something you should try without being extremely cautious and without previous experience.

On the topic of music hardware, another fun thing to build is effect pedals, these are much much safer, and permit to gain valuable experience with a soldering iron.

There are also a few kits available out there, either for effect pedals and tube amps.

For people in Europe, I can recommend https://www.musikding.de

* Tube amps: https://www.musikding.de/guitar-amp-kit-tube-amp-kit-valve-g... (I've built the A15 kit in the past, the components are a bit cheap, specially the power transformer, but it sounds quite nice, and makes for a great 15 Watts dual channels amp).

* They also sell a lot of pedal kits: https://www.musikding.de/guitar-effect-kits

They also sell parts (specially those a bit harder to find at a good price like footswitches, sockets, a wide variety of knobs etc).

Another shop I can recommend for components: https://www.banzaimusic.com/home.php
It’s unclear to me how much should go to founders of things like currency. Shouldn’t the amount of funds to a dev team depend on some sort of measure of value rather than a cut of all future tokens? That seems unsustainable and part of the reason why a cutoff would be designed into the system.

I’ve been through a lot of discussions around what a fair price is to pay for the devs of a community resource and I don’t think I’ve ever seen it resolve well. A few examples I remember are plastic and kur5hin shutting down, digg and reddit and slashdot for selling off with digg and slashdot going into barebones ad models and Reddit doing whatever they’re doing.

One of the big disagreements I witnessed a lot of discussion around was how much founders thought they should get just to run community resources and how much the community wanted to pay. The most concrete I remember was the plastic, or maybe it was netslaves, founder wanting $300/month to run the servers. Not much at all, I think it was between 2000 and 2005. A few members offered to run it for free and he wouldn’t do it because he also needed the servers for his other projects. That spiraled into a boring discussion about why a community would pay for some private servers.
> I spend quite a bit of time thinking about how to transition from our widely oppressive capitalistic system to a more communistic one

The problem, of course, is that without force they’re short lived, like volatile molecules exposed to air. All matter eventually retreats to its most stable form.

Of course, nothing stops like minded individuals from forming communist societies (communes), and they do sometimes. Even a small one doesn’t stay together long without force or a very strong binding identity, such as religion or family.
Meetings aren't real coordinating activities. They're generally listening to a boss drone on about stuff that could have been said in an email for an hour and people asking pointless questions that mostly only pertain to themselves.
For me the issue is not really whether I access the docs through `man` or through the browser. It’s comprehensive, accurate docs provided in one place by the vendor of the tool I’m using, versus wading through a crowdsourced resource like SO which might be incomplete, out of date, or inaccurate.

If a library vendor provides good docs on their website, that’s just as good as man pages, but in my experience they usually don’t.

There is a staggering amount of misinformation or non-existent information on Stack Overflow. For one simple example: try to figure out how to use the GPS on iPhone. It’s simply impossible. 99% of people on SO think “GPS” is synonymous with “Location APIs” in general. Of the 1% of people who understand the several different data sources used by CoreLocation, nobody can tell you which accuracy settings will cause it to use GPS specifically. If you bother asking, you’ll get a bunch of “middle-brow dismissals” asking why you want to know such a thing, telling you to just use whatever accuracy setting you semantically need, smugly claiming you’re guilty of posing an A-B question, and so on. This is the type of dead simple basic information I would have expected to be present in Apple’s documentation, instead of having to crowdsource it from internet trolls.
Seems useful to me. Fixed sized data is very convenient for computers (fits in a register, pass-by-value), and being able to represent 0.1 and 0.01 is very convenient for humans.

The hardware does seem to be of questionable value; I heard rumours that the POWER hardware didn't actually beat the Intel software implementation running on an x86. That doesn't mean that the datatype is worthless.

And it sure as hell doesn't mean that this DEC64 type, which has arbitrarily incompatible parameters but adds nothing, and is late to the game, is better!
You seem like a really unpleasant person and it doesn't really seem worth my time to interact with you, but I want to point out that your post actually contains no relevant information: "to post as I have done" is a tautological reference to my violation, as "to post as I have done" describes the entire sum of my post and behavior. This provides no insight, and seems mainly an opportunity for you to be smug.

My suspicion is that people object to calling this persons' claims essentially a lie, which is just the truth. It is dishonest to use the performance numbers of an incomplete project while listing the features of the complete project, which will certainly decrease performance. The website is replete with obviously absurd claims, like a completely baseless claim about throughput that assumes compile time is linear in code size.

But what's actually pathetic in this affair is the anguish and upset of a bunch of internet nerds over a project that has received, in its 3 months of existence, less than $2500 USD. This is peanuts, but everyone is outraged over a "scam" because the real scam is open source getting a bunch of people to work for free, hoping at a chance of getting peanuts like this.
If all those people believed in them then they would buy from them. Their actions prove otherwise.

It's fine to be an entrepreneur and own a small business that takes part in the local community, but that has nothing to do with the business you're in. Selling regular household merchandise is not a good business anymore.
We use .NET at Degreed. I suspect a lot of startups use it, but not many compared to other startups. The problem is that's they're hard to find because they're not actively throwing it out there that they're using .NET.

It is not applicable to many places in the world where there is no such an abandon of land space and wood supply. The American suburbia has its own environmental impact which might offset any benefit comparing to more congested tall buildings areas.

This kind of post comes up every few weeks here on HN. I also revisit FF every once in a while, last time being when all the news went about Chrome possibly breaking ad-blockers. Chromes UX is still better than FF, IMO.
My rule is: If it's real, then it can be measured, and if it can be measured, then it can be reproduced in solid state circuitry, perhaps using digital techniques if necessary. With that said, whether anybody is actually doing so satisfactorily is an open question. Actual test data for things like musical instrument amplifiers is remarkably sparse. And I won't begrudge anybody the pleasure of owning or building historic circuits.
My friend decided not to have kids. He suffers from health issues and fears it may be passed down and can't cope seeing his children suffer the same way.

At first it struck me as a bit alarmist however having a not so serious issue myself helped me see his point of view. But my feelings about his decisions are never fixed though and sometimes I do wonder if he'll ever regret his choice, especially since genetic issues are not always passed down.
Doesn't it reintroduce the issues with senders detecting if their emails were read and where from by tracking requests?

I'm not the parent so I can't answer from their experience, but I will say that laziness in Haskell lets you write functions that cannot be expressed in Lisp without macros.

Some simple examples are when and unless, which work like if...then and if not... then.

In most languages, these would be control flow statements built into the language (or not) and could not be written by the user. In Lisp you could implement these with macros, with all of the caveats that apply. In Haskell they're just ordinary functions with all of the benefits of being first class values at runtime.

The controversy over inheritance has to do with implementation inheritance, where any method that's defined on a base class can depend on methods that may have been overridden in some derived class, or rely on some non-codified invariants that a derived class might break: this is known as the "fragile base class" problem. By using composition over inheritance, this is not something that can happen by default, because there is no provision for a method call on some "base" method to dispatch on the object's "actual" type, or more broadly to rely on anything but what's defined in the base object itself. You can recover that dispatch-like behavior ("open recursion"), but it's something you have to code yourself and opt into explicitly. This is good for rigor and auditability, as well as just being all-around simpler and easier to understand. Implementation inheritance is too general of a feature, and just not a good abstraction.
"Can the community save itself from the impending crisis" is a bit clickbaity when the funding cut-off has been an explicit step in the plan from the beginning.
I asked about that. It doesn't compile Rust, but only the exact subset and dialect of Rust that was used to code exactly one program: the Rust 1.19 compiler.

In other words, it's not properly a compiler, as such, but a bootstrapping tool. It does important compiler-esque things, but not others, and is useful to no one else.
I'm interested you think the Haskell community is bigger than the OCaml one. Without checking any sources, I would have assumed the OCaml has a larger community of people using it in production for a variety of things, and therefore would have have the libraries etc. for me to build my thing.

I suppose this is my bias - the only community I care about is the engineering side as supposed to my academic side.

Also look at ReasonML (and bucklescript). I have tinkered with it for Web front end and been very impressed.
Their tolerance has reached such an impressive level that they have banned slightly less than half the country.
You could solve this problem in two ways that are pretty easy to setup and handy to use, IMO.

1. You can open a new window, move the new tab in the "Work" container (if you use an extension [1] you can just type "co work" in the address bar), and use alt+c [2] to open new tabs in that window, ensuring they are all opened in your "Work" container.

2. You can create a separate profile for work, running "firefox -p" to first create it, and then create a desktop shortcut that links to that profile. This way you'll have two separate profiles on two separate Firefox "icons" that that you can launch at your will. There are ways to do this both on Windows and Linux (not sure about Mac, never used that), and the setup needs to happen only once. I've had separate Firefox profiles for years now that just keep working without any problem. I even ported some profile folders between different installs (same OS), and to my surprise they still didn't break.
