Because there was no available extra sensor. Trevor gets a few other things wrong too.

The elevator feel system (EFS) uses multiple sensors, in fact it has its own pitot probes[1] (two of them) on the elevator. It's not clear if it uses both, but I suspect it also uses both alpha vanes up front like MCAS should be doing. Input from the alpha vane (AoA sensor) is new on the MAX, IIRC. His tweets were a bit ambiguous, but the elevator feel system does not change the trim at all (also EFS was non-op on the Lion Air bird).

It's almost certainly NOT a sensor problem. Look at the graphs from the black box on the Lion Air flight. The angle-of-attack was almost exactly offset by twenty degrees left to right[2]. That sensor was working just fine, but something else on the path was fucked up (bad wiring? bad ADIRU? both have happened before). The fact that the alpha vane was replaced and that didn't fix the angle-of-attack readings supports this. Also, the 737 NG and 737 MAX use identical alpha vanes. While the angle-of-attack data is less important on an NG, we haven't seen people come out of the woodwork talking about how common alpha vane failures are on an NG. I'm inclined to believe that they're not all that common.

The Lion Air flight crew did write up the sensor problems[3].

I saw another one of these "I'm a software engineer so I've got great insight" posts[4] and chuckled. It's a bit of swing and a miss as well. MCAS is hardly silent or subtle. The same trim wheels his Cessna have are present on the 737 and they're noisy[5]. MCAS doesn't quite override the pilot either, and you can see that on the black box graphs from the Lion Air flight[2]. Twenty times the pilot flying entered opposite trim to counteract MCAS and twenty times MCAS paused for five seconds. On the twenty-first time something changed and the plane crashed. It's not quite that simple and that's why there are active investigations.

Thank you. I hate the black and white mentality of “I can think of an example where merit played no role” which becomes “we are not a meritocracy”.

Sorry to say, but nothing in this world is perfect. However, a lack of perfection doesn’t prove that something doesn’t exist.

There's always beem a trickle of machines like that. The problem is that they're targeted towards industrial usage and RIOTOUSLY expensive.

https://www.bsicomputer.com/products/fieldgo-m9-1760 for example (the first vendor I saw that actually shows prices, as opposed to just request-for-quote)
It starts at nearly $2400 for a low-spec Celeron, and I'm not sure it even has an onboard battery.

What I could see as viable would be a micro-ATX case of similar dimensions, sold as a barebones for like $300-- use the extra volume from not accommodating ATX mainboards to store batteries and charging circuitry, which can be off the shelf because space constraints are minimal. Pop in some reasonably priced desktop components, and you'd have a competent luggable for under $1000.
You might have misread my comment. I find it sad that we do not have these models. I am well aware that right now it is not possible. I do blame on pharma however for not putting massive amounts of money into this fundamental research. I did a lot of modeling and simulation and I know that chemistry and molecular biology simulation tools exist. But I never encountered a call for academic contributions to increase performance or supply general numerical or computational techniques. from my pov the civil engineering simulators (using odes,dates, and pdes) where completely separate from the chemistry world (often using odes and daes).
> F-droid can't sell apps on the play store without using Google

"I can't sell my organic bananas at Walmart without dealing with Walmart"?

I can understand ideas that there shouldn't be a "default store" on devices. Or that Android's certification (whatever that is called) shouldn't require pre-installing the play store as only option. I may or may not agree with them.

But "I should be able to sell my wares at a store without dealing with its owner/operator" sounds strange to me.
This comment raises a relevant question for me: where is my downvote button? I have been using HN for a while, but can only see an upvote button?

Look at the charts above. Both pilots "fought" with the controls, correcting the plane course, then believing "it's corrected now" and then the plane sunk again and again.
Do you mean DEF Blue?
True. However, there are "memory items" that have to be done from memory when the situation does not allow time for a checklist. Stall recovery is one of them, which is exactly when the MCAS is supposed to activate. I'm pretty sure runaway trim is another since it won't take long to end up in a very bad attitude if this happens, especially at high airspeeds.
Its not clickbait, its just efficient language. We have a symbiotic relationship with bacteria in our gut but don't explicitly distinguish it every time we refer to human digestion.

Actually this article and study is not intending to reveal anything new about how trees and other plants fix nitrogen (using microbes). It is revealing that the symbiotic arrangements (far from entirely understood) also cause the breakdown and release of scarce nutrients from rocks, enabling increased growth and building soil fertility over time.
Some actors in new media spread false informations, and this is a real issue. But in China, people turn to blogs as a result of the censorship. ...More filtering cannot be an answer.

You don't combat false news by electing an arbiter of the truth (whoever it might be), because that's the start of a journey in a rabbit hole with no end.

Some possible solutions are forcing an organisation to publish corrections and clarifications, forcing people to critical thinking by engaging them in a civil discussion (one of the reasons I like HN).

Total banning and complete erasure shouldn't be options worth considering.
Playing the game well enough means A- not B+. I used to think about this in University a lot with the grading system. On the face of it nobody really seems to notice the +/- distinction. There is a more primitive grouping of A/B/C. The difference between being an A grade player and a B grade player is 1 point. If you're 79 points you're B+. If you're 80 points you're A-. But it's a world of difference between being perceived as an A player vs. a B player. By that same token, the effort/reward ratio for striving for A+ is crappy.
Understand that "news" is a filtered set of "information" packaged for maximum impact in minimum time. For those in the "news business" they are there to get eyeballs, clicks, etc. for profit or world view support motives.

Basically I am noting that all "news" is filtered, edited, and often creatively rewritten. This is to maximize the likelihood of a particular desirable audience segment to interact with it.

So, yeah, I try to ignore pretty much all of it at this point. I skim some breaking news blogs/aggregators to see if anyone has started a war, or if there are disasters anywhere.

But I've learned to take everything "news" I read with a kg or two of salt. Its worse in science, where creative writing distorts actual discussions. The whole "IBM quantum computer went backward in time" bit from a few days ago is a perfect example of how wrong something can go by ignoring the language given to the reporter/PR firm, and replaced with a more creative exciting (in)equivalent paragraph. This is just one of a plethora of examples, but the point is, you generally cannot rely upon information content being accurate in the vast majority of writings.

I am sorry I am so cynical on this, but honestly, you'll feel much better if you stop reading the "news".

Note: scare quotes "" intentional.

Show HN: AlgoDaily – One-a-day programming challenges for web developers
LineageOS has a tendancy to disable or break piles of vital security features very carefully architected by Google security researchers like verified boot. Google also maintains a release process designed to help mitigate supply chain attacks. LineageOS also deviates from AOSP sources enough that it often creates significant time delays before new security patches can be backported if they get backported at all.

Sadly stock Google phones also violate your privacy and the privacy of those around you. Stock Android is not a great solution either.

I stopped reading that article when he implied that Gates' wealth should be considered or measured in relation to programming skill. Debates about meritocracy are important, but starting from flawed frame like that made me not want to invest more time reading that particular author. If he wanted to compare Gates to other technology entrepreneurs, that might have been worthwhile, but implying that we don't live in a meritocracy because there are better programmers than Gates shows the author is not interested in a rigorous look at the issue. I wasn't surprised to see Bill Gates clickbait at the top of the Apple News app, but I was a little bummed to also see it on the top of HN. Then again, I still clicked it and commented on it, so mission accomplished for Fast Company I suppose.
The BBC should have titled this article "The company that made the worst video game".

As it reads, it was not the developer's choice to crank out a title in a fraction of the time of the usual project - especially on a platform that cannot be patched like modern games.

Yes, he accepted the deadline, but when management is obviously aware of the risks imposed by time, the failure is the responsibility of more than just the coder:

Using Vim without knowing WAY more than this article is an anti-pattern. Vim is inefficient for editing so you have to learn a lot more than these tricks and hacks to be proficient. If you aren't learning more about Vim's nasty design every day then it's an anti-pattern to use Vim, because you'll be much more efficient with less learning in any other editor. If, for example, you don't know how to edit searches and command-line mode commands in full Vim mode, then keep learning (press control-f in search mode). If you aren't proficient in Vim's garbage VimL then keep learning. Obviously an IDE with intellisense and multiple cursors is more efficient than most of Vim's efficiency hacks. Vim's efficiency gains more apply to editing text, not structured code.
Why are we even comparing programmers to Bill Gates ? He was an a business owner, an entrepreneur.

The world doesn't lack highly skilled entrepreneurs who take a lot of risk.

Gates, besides being very talented, was extremely lucky - being at the right school at the right time, having a mom at the board of directors of the largest computer company in the world(IBM), and having IBM make the worst business decision probably ever - feeling that there won't be much money in the operating-system - so licensing it out.
No. It does not work as a filter.

But if you have a high amount of applications then statistically it may work for you. Same as throwing half of the CVs in the bin, as you only hire lucky people.

Github and SO data is a conversion point, not a filter. Sure I am also suspicious if no public profile, but never exclude as it often has valid reasons.

My personally github code is a lot more slapdash than my commercial github code. Nearly all of my commits in commercial github repos are private repos so not on my profile except in the activity graphics.

I have worked with and hired really good developers with a great public github profile and with lots of SO points. I have also worked with many very experienced and good developers with no github or SO presence. And I have met people with lots of SO points that I never want to work with again.

But if you got too many applicants you can apply whichever filter you want. It just wouldn't work for me, or my location (London)

> A cute trend, especially in Lindy Hop circles, is to wear vintage outfits from the 1930's and 40's.

Some scenes in the US apparently went too far with that. When too many new people started coming in in their best vintage outfits, there were a few (current teachers) who made a point of going to competitions as casual as possible.

> In the past it has been the tradition that men asked women to dance. But this custom has gradually changed. Today, women should feel equally comfortable asking a partner for a dance, even in a formal setting.

Also fortunately these days many scenes are closer to "smash the patriarchy" idea and people are happy to dance with whoever. There's no role assignment, which also helps when there's no balance in genders in the room.

Technically MCAS activation isn't runaway stabilizer trim, and I'm sure that tripped up the Lion Air pilots. Check out the quick reference for a runaway stabilizer[1]. Note the steps:

* Control airplane pitch attitude manually with control column and main electric trim as needed

* If the runaway stops, stop.

Well, electric trim input on the yoke will stop MCAS temporarily. Of course if these guys had any experience on an NG they're already used to the computers trimming the plane in a counterintuitive manner via the speed trim system (STS). So not only is MCAS not a runaway trim situation, but pilots flying the NG will get used to the computer trimming the stabilizer "at random".

Stackoverflow seems interesting as an inclusion of that level.

As already stated, Bill Gates and other billionaires are pretty irrelevant to this question. Nobody really cares what it takes to become a billionaire, almost nobody will become one anyway.

What matters is if talent and hard work pay off, and they most definitely do. Yes it helps if your parents are rich, but that’s ususally because of _their_ hard work so that’s not really a counterpoint, and most successful people come from average backgrounds.

So yes meritocracy most certainly exists.
IBM could have had (something like) Windows. They famously misunderstood that they commoditized themselves out of the whole-PC market, and the truly big players to remain would be those to achieve mastery in creation of the components of the market. Like Intel and CPUs, or Microsoft and software.

All the "non-free-speech", "speech is violence" advocates here:
Violence, call for violence against others, and crimes that happen to have a speech component to them, are NOT protected by the first amendment. Threats against individuals and CP very much fall under crimes, and they have ZERO protection under free speech.

> If you want to make the case for no censorship at all then you need to use the most extreme examples of what will be shared and consumed because that's what will happen

No free speech advocate worth their salt EVER demanded anything illegal to not be censored, including threats, CP, etc.

Absolutely no one should entrust private corporations with the power to decide what is and isn't extreme, or acceptable speech. Because it will immediately be abused (as is happening right now) to censor speech that companies, mostly based in left leaning blue cities with, overwhelming employee bases leaning towards one ideology (hint: left), to spread their worldview to the REST of the world. US law sets clear definitions on free speech, and is a lot more reliable than the "moral" compass of a few individuals at companies.

For instance, the very legal and harmless "learn to code" meme was only considered offensive by a very small monitory of silicon valley Twitter censors, but anyone who tweeted that got an immediate temporary suspension.

Acquiring child porn doesn't have to be any more difficult than acquiring videos of beheadings and other vile acts. It was only made difficult to acquire out of puritanism, there's nothing intrinsic about it that suggests you have to commit further crimes to find it.

And if the idea is that the public is too dumb and easy to influence and therefore cannot be shown child porn or killings in New Zeland etc then it doesn't make sense at the same time for me to be advertised violent movies in the cinema.
> My main point is that a global CPU graph helps you identify acute CPU consumption as it happens which is the main mechanism that helps me identify things like Spotify getting stuck in a spinlock or a browser tab devouring my battery. Seeing "Google Chrome" show up in Activity Monitor's energy chart when you check it periodically isn't as helpful.

If you want to know 'what is using all by battery' after a couple hours using it, you want to know the average power usage by app, which activity monitor gives you. Battery life is the point of this thread, not random lock ups.

> Good point about iStat Menus consuming its own resources. It has two processes afaict with its main process staying below 1% CPU.

I wish we could just get rid of 'cpu %' as a metric on modern machines, or at least scale it based on P-state. Saying process X is taking Y% of the CPU is pointless if you don't also communicate the P-state, and chances are you don't even know which core the process is running. Point is, I'm sitting here almost completely idle and there are plenty of tasks 'using 3-5% of my CPU', of course the CPU is running at 800MHz no where near it's all core peak of 2.7Ghz, much less it's single core peak of 4.5Ghz. What does 1% CPU even mean in this world?
