Yes, the lead raises the effective octane, preventing detonation. The other tool for preventing detonation is running extremely rich fuel/air ratios, the typical setup for the airplane at full takeoff power.

You target an appropriately rich mixture at sea level when tuning the carb or adjusting fuel flow for injected engines. The pilot manually leans the mixture as the aircraft climbs to maintain a reasonable fuel/air ratio.

Owners sometimes call that mixture lever the money lever because it governs fuel flow, aka "dollars spent per minute".

Surely you can't be suggesting that an entity can only be considered a "legitimate" satirist if it's been around for a long time and there's a high amount of consensus regarding it?

Also, you cannot use network effects as an accurate proxy for critical thinking. Humans inherently defer a ton of thought to crowd consensus; this crowd consensus becomes less reliable as the subjects involved become more complex. The increasing complexity of modern society only further necessitates the need to train our critical thinking skills. Codifying network effects as a proxy for critical thinking, as FB is doing here, only accelerates the unreliability of groupthink.

Wikipedia article about the worm:

Is git (at least the SCM of a big project, the kernel, say)... not a block chain? The hash chain is (notwithstanding some recent discoveries) secure, the series is externally archived, "proof of work" is provided by trusted human review.

Obviously no one uses the kernel series to store arbitrary data on behalf of the patch submitters. But you could, without modification to the software or processes.
Well, 50deg LoP is the same EGT as 50deg RoP.

But, in general, leaner is hotter, not cooler. At a ROP setting, the extra fuel that is not burned lands on many of the top end components including the exhaust valve. As it evaporates off the surface or out of the fuel/air charge, it cools the component or charge.

Also, peak cylinder pressures are higher when run RoP.

In any case, the Cessna 172S Lycoming IO-360-L2A (engine) handbook says, "Continuous operation at mixture settings lean of peak EGT is prohibited"
So who gets to be the ultimate keeper of truth? If CNN spins a story to be police brutality, but you happen to be an eyewitness who saw that it was actually self-defense, can you mark the CNN story as disputed? Who decides if you are right or wrong?
Well if we really believed in the free market and consumer protection, there'd be a law requiring the total transaction cost be printed on the sales slip. Whether the merchant pays it or passes it onto the consumer would be up to the merchant, but the amount would appear on the slip so the consumer sees these costs and who is paying for it.

What we really have is mercantilism, where the issuer by contract disallows full information to be conveyed to the consumer without the consumer's consent, and this is in effect protected by law by the fact it isn't illegal. You could also call it an example of chrony capitalism.
So are you allowed to this to your own personal plane (engine swap with non standard engine)? Or do you still have to get FAA approval even for private use?

I guess I'm wondering if there's a grassroots community of people doing engine swaps on their planes?

the infinite values between 0.1 and 0.00000000000000000000000000001 is infinite and thus nothing. It's in reality a gradient with no distinct steps.

Only when you reduce reality (like humans do) and you start manipulating with symbols do you get mathematics.

This manipulation with symbols (and it's foundation of a quantifiable universe on top of a quantum universe) is the foundation of math, not the other way around.

Math is simply a way this underlying reality gets expressed, it is not what the reality is.

The Cessna 172/182 types are fine aircraft, but I really would have loved to have seen some more innovation over the years.

When I was a student pilot, we did our first handful of familiarisation and evaluation flights in a 172. The instrument panel looked like someone had cut holes in an ironing board and stuck dials in it. The seats were no more than a 2 piece metal bench that someone had stuck thin cushions to, and the seatbelts would have looked at home in a 1940's car.

Then we transitioned to the SOCATA TB-10 Tobago for the rest of our training. It was like switching from a Russian built car to a Lamborghini. The instrument panel was ergonomic, recessed for shade, and the engine instruments were actually canted to face the pilot. We had Recaro racing seats in the aircraft which made long navex's more bearable. Inertia reel seatbelts. Gull wing doors that helped cool the aircraft quicker after sitting on a hot tarmac all day. Throttle controls that looked like a jet fighter instead of pull knobs.

The European design was simply leagues ahead, and made the flying experience so much better. I am thinking a major reason for the longevity of the Cessna training line is more to do with cost for budget conscious training schools, rather than being a better aircraft than any other trainer.

Cirrus just certified the SF-50 Vision, a new single-engine VLJ.

Cessna doesn't call it this, but the Mustang is pretty close to VLJ sizes. (Not many being made though, as their M2 pretty much took over that space of the market.) The Embraer Phenom 100 is similar. Both have been reasonably successful.
Option (a) create a 'motherly' machine which is guaranteed compassionate towards children and small furry mammals,

Option (b) create a Buddha-like machine which is guaranteed benevolent towards everyone and everything in the Universe.

Neither of these work! Wrt (a) the flip side of maternal empathy is a ferocious attitude towards potential predators who threaten her cubs. How does the programmer guarantee no human will be placed in this category, mistakenly or otherwise? Besides, before one attains motherhood one must pass the 'terrible twos' which many psychologists regard as the peak stage of physical violence.

Wrt (b) an AI with no desires has no incentive to interact with the world. So its mind will not develop.

Is there a third option?

How to Create a Tech Blog
Unfortunately there isn't really anywhere else where facts are not censored, shadow-banned, or shilled into oblivion. For instance, pre-election, I made an entirely 100% truthful meaningful comment on this site, a story about a Wikileaks email dump, I pasted several links directly to the Wikileaks DKIM verified emails for reference. I had a dozen or so up-votes, then stopped receiving replies. I posted on the other similar story which was very hot, and received no votes in either direction, nor any responses. Upon logging out, realized I had been shadow-banned. Ten or so posts appeared on inline on the stories, but every single thing I typed, would only show up if I was logged in.

After searching everywhere for rules, or anyone anywhere mentioning that hn shadow-bans dissent, or shadow-bans anything for that matter; I emailed hn. I received a reply saying that I was indeed shadow-banned, however, it was in response to a comment I made 300 days prior. In summary I comment with facts and sources in a respectful passive manner in response to a fallacious top comment, get up-voted, and then shadow-banned 15 minutes later for that comment, and everything subsequent, but because of a comment I made 300 days prior. #FreeSpeech

>Why should I trust this guy's conclusions over a joint report by the NSA, CIA, and FBI released by the Senate Select Committee on Intelligence?

The three intelligence agencies that issued their concurring opinion didn't actually do any investigating; they took the CrowdStrike report of the incident at face value.

Which, itself, means that the government's conclusions are only as good as CrowdStrike's conclusions. So the real question to ask is whether or not you should trust this guy over CrowdStrike.

> I am thinking a major reason for the longevity of the Cessna training line is more to do with cost for budget conscious training schools, rather than being a better aircraft that any other trainer.

Yeah, budget and familiarity. I doubt Cessna is selling many 172s to anything other than flight schools.

How effective will any tool, widget or service be at weeding out "fake news" when one can't counter a questionable news source in social media without being called "snowflake" or some other pointless pejorative for committing the cardinal sin of disagreeing?

How Alcohol and Caffeine Helped Create Civilization
I think this article is a little miss leading. I did most of my initial flight training in a 172 I bought with a friend. We had it parked in Tucson near a company that was building custom planes and blazing the trail in glass cockpit design. After a couple years I had built friendships with a number of people there and built the following picture of the industry:

Innovation in private aviation is so small that it's dead, this isn't because someone owns the market but because FAA certification of new technologies is a 15 year not like 20 to 25 year process.

Why? You ask?

Starting in the 70s and into the early 80s there were a number of high profile crashes of private planes. Think Woz, a number of these crashes were due to pilot error, but a number of them became civil lawsuits where the operational complexity of the aircraft was blamed. The FAA was called upon to develope stricter standards which put many private aviation companies out of business. Cessna survived but based on the high price of getting new tech certified which lowers competition there is a way lower incentive for them to change the design.

Many of the parts in the engine of my 172 were OE ford parts found on cars in the 60s but the FAA certified stamp meant we would have to buy the 300 dollar version.

TL;DR: the enduring success of the Cessna 150-180 is actually a tradgedy of blocked innovation and not something to be proud of.

In Finland I went through several hundred rounds. Wasn't even regular infantry. Served the shortest term possible in the signals corps.

Training is scheduled into three parts. 8 weeks, after which you are assigned into leadership track or your rank and file specialization. Then 5 weeks of personal specialization training and 7 weeks of squad training. Adding to 6 months. There are some more difficult rank and file assignments, lasting 12 months. Rank and file medics stay for 9 months.

NCO training after that initial 8 weeks is in two parts, 7 and 9 weeks. Those sent to reserve officer training swap the latter 9 for 14 at the reserve officer school. NCOs lead after that for 28 weeks and reserve officers 23.

Finnish conscription is very limited in its selectiveness. 25k conscripts serve yearly, which is roughly 70-77 % of male cohort. The numbers add up quickly: there's a massive trained reserve of 900k which eclipses most of European armies combined. Their usefulness is obviously somewhat debatable. Still all of them had 6-12 months of military training at some point. 230k have actual war time allocation and up to date kit. There's a similar 12 months of civil service or serve jail time "options" like in Norway. In 2009 2,5k picked civil service, 25 went to jail and 20 took a very niche option, which is to serve unarmed.

Answer to question "in your opinion, if Finland is attacked, should Finns take up arms in any situation, even if the end result seems uncertain?" has been very high for the whole of 2000s: 71–81% say yes. So the willingness is high, owning to mostly to geographical realities. The same thing which has ensured that there's never been serious intent on getting rid of conscription.

25 years ago was when the US incarceration rate was ballooning. The 80s and 90s were the start of a massive surge in incarceration[1], up from the baseline. The idea that the US is improving and other nations have 'stopped' is only because the US departed so significantly from the pack in the first place. Similarly, while the US has a ridiculously high homicide rate, most of the people in prison are not murderers.

The way you're phrasing it is like saying "The A+ student has stopped improving, whereas the failing student is still failing but improving[2]. One day he'll catch up to the A+ student"

As for the odd sentences you mention, you can cherrypick weird sentences in any system. In Texas, for example, there was a black 14-year-old who punched some and they died, and he got ten years for it. There was a wealthy white 16-year-old whose reckless driving killed four and injured seven, and he got no jail time for it. The defense arguments included 'he never learned to say sorry because he was brought up wealthy - you sent money instead of saying sorry'. The kicker about these two sentences? They were issued by the same judge [3]. In California, another serious case ended in a significantly reduced sentence because the judge thought that the defendant's wealthy upbringing meant he wouldn't be able to 'survive prison as well'. And New York is replete with stories of people being incarcerated for years without a trial [4]. Then there's the famous 'pizza-slice' felony, where three-strikes laws sent a man to prison for life for stealing a slice of pizza [5].

The point here is that you can find all sorts of oddities in sentencing - what really matters on a national scale is the aggregate. You mention the sentence for that single child molester - is that happening for a large number of such cases?

The US system is ridiculously fucked up, and it has to improve a lot before it can join its contemporaries. Given the general American public's bloodlust towards punishment, it ain't gonna happen.

edit: sorry for the waffle, I just find the US incarceration system both fascinatingly and horrifyingly out-of-the-ordinary.

I once had the opportunity to listen to an extremely talented WiFi expert from Aruba Networks explain on a whiteboard to a rapt audience of infrastructure engineers how this works. And how adding multiple SSIDs is a contributing factor to this problem.

The most fascinating piece was what he called the "butter factor". The closer a substance is in consistency to butter, the more it will absorb WiFi signals. Aruba had one heck of a challenge installing a WiFi network in the Land O'Lakes manufacturing facilities. They had to use directional antennae mounted mounted at eye level down each aisle of the factory.

I've been saying that for a while. Uber is losing $800 million per quarter. They run out of cash in 2018 unless they can find a bigger sucker than Saudi Arabia's sovereign wealth fund. Uber is cheap only because investor capital subsidizes every ride. (And because they keep squeezing the drivers harder.)

IPO? They'd have to publish audited financial statements with GAAP numbers, which are almost certain to be worse than the leaked numbers. They'd take a big haircut on valuation, which the existing investors would not like. (Who has voting rights in Uber, anyway?)

Uber will probably run out of money and be picked up cheaply by some buyer of distressed companies, which will raise rates and cut it back to a profitable operation.

Any kind of personal question becomes hilarious. What makes it hard and extra fun is that every time someone answers wrongly, the person they're answering for (or anyone else) yells out "psychiatrist!" and everyone switches places - answers to the same questions change.

Ask HN: Mentor/Advisor for post-revenue EdTech Company?
Hello,

EdTech is a wonky industry! Many downsides... but rewarding (social + profit) if you can carve out a foothold and grow your installed base.

We're a small, bootstrapped, EdTech company in a niche space (think desktop application for a humanities field) that's looking for mentorship from an experienced EdTech veteran (either on the tech or business side). We've grown annual revenue to ~$600-700K (~$400K of that is ARR) across a variety of accounts: K-12, Universities, large publics, small privates, etc.

Product engagement and customer satisfaction is great; we have low churn at an expensive price point + high conversion rates on pilot trials, but we're struggling to level up and grow to the next stage (which we define as $1MM+ ARR or an installed base across 500-1000 schools).

There seems to be many older/experienced operators in the B2B and B2C spaces. Finding mentors in EdTech has been difficult for us.

If you have a background in EdTech and are interested in mentoring a small, but hungry team, drop me a line: edtechnovice [at] gmail.
