This isn't quite true. It is up to your issuer if they decide to approve the transaction despite failing AVS or CVV checks. Often they will decline the authorization, but depending on their risk signals, might decide to approve it. Then, the merchant (or the processor they are using) can decide if they want to let the transaction go through despite the failed checks, or call it a decline and reverse the authorization, which removes the pending charge. Crappy terminals might cause the pending authorization to sit there for 1-3 days by delaying or not sending the reversal, but in general that shouldn't be the case.

The problem is total sales are going to be tiny. You might sell 2,000 aircraft per year with an amazing design, but that's just not much to justify a lot of R&D. So yes the FAA could make it a little cheaper, but don't expect that to change much.

I wouldn't call either of those trainers. Don't get me wrong, owning a 172 is fine and I'd love to own one. I just wouldn't buy it and say "boy, I've got a fancy, sporty airplane here," even if you stick a G1000 in it like those Cirrus models.

It's a workhorse, like a pickup. Cirrus aircraft are a lot sportier. (You are correct, though, the SR22 sells like hotcakes. I think it's #1.)

The Merkle tree is only used within a Bitcoin block to store transactions in an efficient manner; it isn't part of the block chain. A block chain without consensus isn't even a tree: it is just a singly-linked list with cryptographic guarantees that given a linked list node, all previous entries can be "verified".

However, as other people have pointed out, this implementation is so incorrect that it fails to even do that: it contains only the hash of the previous data, not the hash of the previous node, so this actually only manages to verify the previous one entry of the chain :/. This is essentially just a linked list :(.
You really need to think about security as a few distinct, but related parts. There's (at least) infrastructure, data and product security to consider.

1. Infrastructure security is because you don't want intruders on your servers. If you don't control access to the actual servers and your own SaaS accounts, and have systems to detect and alert when something abnormal happens, then all bets are off.

2. Data security is because my data is important to me, and I want you to keep it confidential. Store it encrypted. Encrypt in transit, even inside your network. Don't send confidential stuff over Slack. The data a customer puts into your SaaS product should be safe and secure from anyone else who wants to see it.

3. Product security options are required when selling any SaaS offering today. Build and enable 2fa. Build a feature to allow for role based access controls. Don't build any system that would enable you to send me my password in an email. This is a huge list to make.

We recently launched an open source guide for product managers of SaaS applications to use when trying to build for the enterprise. It's at https://www.enterpriseready.io. There are a few relevant sections for this conversation: Product Security, Audit Logs, Role Based Access Control. I'd encourage you to read those sections, and send any feedback. Our team has been working on problems in this space for a while now, and put a lot of time into building those guides.

I lost $100K+ on AdSense due to what I believe is a nasty competitor seeking to get my account disabled. After making the case to Google, they said they would reinstate the account and pay me what was owed. I then suggested measures that we were going to take on our end to prevent competitors from doing that again, and lo and behold, 24 hours later the Google rep tells me I'm not getting paid. No lawyer was willing to take the case, because it's Google.

I literally lost $100,000 because I suggested to Google that we would take proactive measures to prevent fraud. As if having the knowledge to do so meant we were committing fraud.
There was a Decision Analysis class at Stanford that took this idea to an extreme. For each multiple choice option, you had to indicate the percentage confidence of that option being correct. The percentages for all 4 options had to add up to 100%. The score you got for each question = 1 + ln(confidence-assigned-for-correct-answer).

So if you were completely sure and gave the correct answer 100%, you would get a score of 1. If you gave it 90%, you would get a slightly lower score. If you "guessed wrong" and gave the correct answer 0% probability, ln0 is negative infinity, so you would instantly fail the entire assignment. It was a pain, but it really made you reassess how well you know stuff, rewarded people who truly knew their stuff, and burnt anyone whose confidence exceeded their actual abilities.
If you want to be so general, then anything can be considered mathematics, at which point it kind of loses its meaning. For me, mathematics is any system of symbolic manipulation built on top of axiomatic set theory, ideally having some algebraic structure. Given that the universe is comprised of things and not symbolic representations (unless you want to get really general about what a symbol is) that seems to disqualify it right there. Can we approximately describe the universe using mathematics? At the gross level, with the inclusion of fuzzy sets/probability theory, sure. At the fine level, I'm not so sure we can accurately represent the universe using less information than the universe itself contains - thus you aren't abstracting anything.

I mentioned the incompleteness theorems because they suggest a universe that was a consistent logical system would be arbitrarily constrained from valid portions of its state space - a testable hypothesis with no evidence. Of course, if you toss out consistency then all bets are off.
This is a well understood phenomenon in the history of science. Nothing new here.

I'm not sure the Cirruses would make very good trainers. If nothing else, I think you'd want something where the spin recovery procedure is something better than "pull the big red handle and call your insurance company."
I said Platonism because that is the point of view that mathematical objects are real. As far as I can tell no other point of view asserts the fundamental reality of mathematical objects. And just because I am not absolutely sure I said »a form of Platonism« which I would admittedly better have worded as »something like Platonism«.

To you point about quantity. There are grains of sand. Does that mean that there are also numbers? I obviously argue no. You have to take some of the grains and set them aside to count them. You have to split your pile into two and recombine the two piles to add them. You have to line the grains up in order to number them.

By itself there are only grains of sand, mathematics only emerges when you impose additional structure on them and perform operations with them. There is no addition in a thousand grains of sand, it is the act of separating and combining them. Or at least imagining to do so.

You can build a huge part of mathematics on top of set theory but that does not mean that all of mathematics is already contained in every large enough set of things, at least not in any meaningful way. Only when you decide what to with the things in the set, what kind of manipulations you are willing to consider, that the structures mathematics describes emerge.

And while physics looks very mathematically, I see no problem with this. The most simple rules can give rise to staggering complex math. I find it much more reasonable to think - gross oversimplification ahead - that photons travel in straight lines in a three-dimensional space and therefore the electric field follows an inverse-square law instead of assuming that the universe already contained the mathematics needed to deal with electric fields.

There are just photons moving around, only after deciding how to measure distances and to look at spherical shells around charges we find a particularly simple way to describe electrical fields. But we could have made a lot of different choices leading to wildly different descriptions.

What do you mean by "lost $100K+". Does that include revenue from potentially fraudulent traffic?
The thing is, if it's impossible to tell if that traffic was fraudulent, Google is most likely reimbursing the advertisers. It's not like they are putting the money in their pocket.
Haha, yeah, though to be fair I think we should build that particular handle on everything and train it appropriately, while still training spin recovery. Airframe parachutes are a great idea.

AMD's Ryzen on GloFo's 14nm process seems to be highly efficient up till 3.3GHz - even better than Intel with its better process. So I think that's great news for the notebook APUs, but we'll have to see. Apple has already started using AMD's GPUs in some devices, so I could see them moving to AMD in the near future fully or almost fully.

And before anyone says that Intel may still offer better performance, if Apple cared about absolute performance, it wouldn't have switched Macbook Air from Core i5 to Core M chips, which likely lowered performance compared to previous generation Macbook Air, or at best stagnated it at the level of a few years old Macbook Air.

If switching to AMD will lower the Macbook's BOM costs by 20% (from about 40% represented by Intel chips in ultrabooks now), I think Apple will do it.
In small programs like this, it might not even take a lot of effort. It's trivial to read a program like this and make a very good guess as to where bottlenecks are without even running it, let alone profiling it. That kind of simplicity gets lost quickly, however, when programs grow.

Then again, I don't really believe that the optimization opportunities are likely to ever matter much. At least not at this level. Perhaps for much more complicated things, e.g. a kind of compile-time sql or string-matcher the greater safety and the symbolic nature of the macros will let programmers write libraries that practically reason about instructions you give them and choose optimal strategies where C would need to do so at run time or with unmaintainable and unusable macros, but if it's just aliasing and some threading gains - well, those aren't huge often, and where they are, C can use em unsafely too (and that's often quite doable too!).

Safety and maintainability sound like more realistic selling points to me - it may never actually beat C in real-world performance; but it doesn't have to - it just needs to come close.

Of course, the actual solution to using i as a counter in a loop is almost always to elide the counter entirely, using an iterator. Expanding on that principle - if you have something that seems to evade a good name, perhaps you're at the wrong level of abstraction.

The 172 simply has some advantages even after all those years. First, it is known everywhere (also its quirks, which makes is safer). Second, the high wing makes it perfect for the young pilot to fly. And third, it has space! I, at 1.87 meter length, can sit comfortably in its back with some spare headroom remaining. I can't tell this of many other aircraft in a similar segment.

"We have found that there are two types of publishers who may have invalid traffic issues with their accounts. The first are publishers who may unintentionally send invalid traffic to their accounts, typically by testing on live ads. For those, we hope that increased transparency into our policies and processes can decrease these unintentional violations and help our publishers play by the rules. The second are publishers who intentionally bypass our rules, ending up with a variety of invalid traffic issues in order to artificially inflate their ad revenue. That’s why we work hard to maintain a policy compliant ecosystem for our publishers, advertisers, and users. In short, if you play by the rules, AdSense is here to help you grow your business."

I feel that this a slap in the face to any people who face malicious adsense abuse traffic in an effort to attack their site. Google has once again just brushed this by.
That's simplistic and short-sighted. People usually talk butterflies, and then turn around and commit horrors, while your crowd will be gazing at the butterflies.

The smooth-spoken actor Obama has successfully branded himself a liberal champion, and now receives the same (similarly fake) adulation on the left as Reagan on the right. When people think "Obama", they think of the smile or nuances speeches (all appearance).

They don't think about the only things that really matter, actions. Obama used espionage laws to imprison journalists. Where was the outrage in the media? People now are calling Trump dictatorial and anti-1A, when all he's done is criticized news outlets in tweets, never (yet) used laws to limit freedom of the press.

This is just an example. Reputation, in the public consciousness, is based on appearances, and you can see how cancerous that becomes, and how easily manipulated it makes you. People not judging others solely by what they do is why democracy is so weakened today.

I had a similar problem getting a new MacBook Pro with a UK keyboard. I live in Hungary. Ordering online in Hungary or buying in a store gets you a Hungarian keyboard. The U.K. store won't deliver to Hungary. In the end I got a flight back to the UK to pick one up.
I think it would be wise for those who cannot begin to fathom, the possibility that Trump has good intentions and knows how to execute(but not the best communicator) while Obama was a criminal and may very well be arrested in the near future, begin to prepare themselves for a massive shock. It explains the amount of $ being poured in to fund and organize useless protests, or protests with minimal (extremely minimal) chances of any impact whatsoever. It also explains why different media outlets, who are in a financial free fall, continue to "misfire" or "misquote" (lie), while they have record low (and still plummeting) levels of trust among an also plummeting viewership.
I love the idea of the parachute. But it seems like the sort of thing that ought to be a backup if you can't recover, not the one and only thing you do.

I'm not a flight instructor, but I have to imagine that inadvertent spin entry is something student pilots might do from time to time, in something that can spin. (I did all of my initial training in craft that refused to spin with my weight in them, so it's a bit theoretical for me. I did get spin training later on in something that would actually spin, and I'm glad I did.)

I'm surprised the article doesn't mention the Cessna 182, which also started production in 1956 and is still rolling out of the factory new today.

While the article extols the virtue of the 172's engine, the fact is that the vast majority of them are running very old designs with carburetors and on Avgas. Avgas still contains lead. These old engines are hugely inefficient and flown incorrectly prone to cracked cylinders. Newer models are fuel injected and there are also a few diesel conversions.

All Cessna single engine aircraft now have to undergo supplementary inspections (SIDS), at least in Australia and I think it is the same in the US. I've seen first hand the horrendous amount of corrosion which can hide in a 50 year old aeroplane and not be found until the wings are removed. These SIDS inspections have the potential to ground much of the older 152/172/182 fleet and render what was a $25,000 asset practically worthless. It will be uneconomical to repair in many cases.

The above has happened to me personally with a Cessna 182. In the end it was sold for scrap with only the engine and avionics retaining any value. I've also seen the costs of these inspections on a Cessna 210 exceed $20,000. It needed a whole new main wing spar amongst other things.

The point I am making is that these very old single engine light aircraft need very meticulous inspections now to ensure they are still safe to fly. I do believe there are probably quite a few seriously at risk aeroplanes still flying today, especially if they have been left outside in coastal areas for any length of time.

I used to own a light aeroplane maintenance business.
that spinner...
In the last 60 years, automobile engines have improved many times: for instance, the 4.4 liter 8 cylinder engine powering the 1954 Pontiac Chieftain[1] produced as much horsepower and torque as the 1.4 liter turbo in my 2013 Chevy Sonic[2] - and it's not even a particularly good or modern engine. (Disclaimer: I work for GM, I'm using these models because I'm familiar with them)

Has the engine in the 172 been improved in that time period? The article says it has not, but I can't imagine using 60 year old tech like that.

I understand that it is "proven" tech, but that would be like saying that punch-cards are "proven" tech nowadays.
