Stiffness is usually not considered strength. Strength, whether in compression, tension, or shear, is usually defined as the load it can handle without plastic deformation or fracture. Elastic deformation is by definition reversible once the load is removed.

Titanium actually isn't that stiff, either. It's quite a bit more flexible than steel. New martensitic steel alloys can be close to a match for the best titanium alloys for strength/weight ratio as well.

Since this material is less dense, it should provide better stiffness for weight, since thicker members can be constructed with the same weight. Much like how aluminum bicycles have much larger tubes than steel ones, to make up for the greater elastic flexibility of aluminum.

Well, if I remember correctly, they track your web navigation using that little like button on every page (even if you don't click it). Then there is the issue that its working on identifying exactly who you live with, where you work, who you socialize with etc. These are things that i can think of right now, and im sure there are a lot more.

Edit: While you where talking mostly about content of fb, i see these issues as being the biggest problem for me personally. I was on the internet in the late 90s and we learned early on never trust anything written on the web, and i apply the same to FB/Twitter/HN/Reddit etc.

I think jedberg is saying he wants to be able to load whatever software he wants on a device he owns. Is this really controversial? There's no good pro-consumer argument for making it impossible. It's OK to make it technically challenging to prevent malicious software from getting on lay people's devices, but blocking it full-stop? If I own a device I should be able to put whatever I want on it. It's mine. Ownership means something. I'm not licensing my phone's hardware. I own it. I can smash it to pieces if I want, why can't I change the bits inside?
It's flamebait because it's not a new critique, and it's tangential to the article. So it's likely to attract people trying to rebut your critique, but neither your argument not the rebuttal would add anything new.

The fact alone that it's lighter than titanium is a big deal. That's great.

Good point. But in general, one can sense an overall picture emerge out of a comment stream. As you scroll and read comments, you can tell when the stream provides value or not. My point here is, that when people do not stay consistent to the original topic, the value of the comment stream goes down. And here, I'm not talking about comments being totally out of context of any given original topic. Even a slight divergence leads to unnecessary path down the road.
Ex Amazon here. The attrition rate is much higher than what most people expect. Yes, the company does stack ranking... unofficially.

Those are prior flights. The aircraft was fully repaired:

> The chief executive officer of Lion Air, Edward Sirait, said the aircraft had a "technical issue" on Sunday night, but this had been addressed in accordance with maintenance manuals issued by the manufacturer.

So you still haven't supported your extraordinary claim that the aircraft was:

In fact we know it was safe on takeoff.
My dad spent his career as a customer service engineer for IBM. When I was about seven years old, back in the '70s, he took me to work at one of his accounts, the Washington Post. He showed me their room full of mainframe, and opened up a cabinet of core memory, thousands of wires and tiny donuts. Now and then, when I use a thumb drive with hundreds of billions of stored bits, I think of the day when I could see every individual bit in a box almost as big as I was.

Sure it looks new and mobiley but all I really want (not OP btw) is the same site but with bigger buttons on mobile.

I have it set up on iOS to auto zoom and to raise the font size a couple clicks but the action buttons are still hard to click on and at least once a day I flag or downvote something I have to then undo.

I'm fine with whatever laws our representatives enact to deal with the situation. I'm completely against those (citizens or not) who decide they'll just break the laws because they don't like them.
The communication services are predatory. Anecdotally, using a cell phone or cordless phone subjects you to having your call terminated due to '3rd party calls are not allowed'. When contacting customer service they pointed me to FAQ where it said cordless/cell phones should not be used and re-queued me without listening to my complaint. The rate given when pre-purchasing funds was $3 plus applicable fees/taxes for a 15 minute call. Except the jail limits calls to 10 minutes. The system is set up to make the cost ambiguous. I've had the service disconnect me within moments of connection and they could care less. I've reverted to writing post cards (letters are banned too, seems convenient for their bottom line). Family members of those incarcerated are preyed on by these monopolies deemed ok because 'its jail'.

How Money Works
Oh I still remember the dawn of Medium: What a revelation this thing was!
A wonderful platform, made for the reader! Nice typography, good layout, easy but pleasant on the eyes.

Oh what does Medium have become...
Meanwhile it became the villain in the game. (The Batman quote would really place itself nicely here)
I asked my mobile provider (Rogers) if they had any alternatives to storing my birth date as my account verification method and they offered to enrol me in their voice print program. I declined.
No matter how many people you hire, at least half of them are going to be at or below the median for your new employees.

So I'd say 500. You'd have to be very good at hiring to get a lower number, and judging from my anecdata, companies that hire software pros use hiring processes that are terrible predictors of future performance, if not entirely useless.
I would bet this is going to get a lot more common as a whole generation of heads-down nerdy programmers who got into the industry because of sheer geek joy get replaced by Stack Overflow copy/paste Uber brogrammers who are just looking for a paycheck to fund their weekends in Tahoe. I mean, that's OK and all, but they need to stick to making Fyre apps that crush it by changing the world through social influencers or whatever and stay away from heavy machinery like automated cars and fucking airplanes.

Sadly, supply and demand isn't going to let this happen. This, combined with rampant ageism that forces out the older workers who know better means we're all going to be seeing this a lot more over the next decade. "Remember when that Facetime bug made national news?? LOL! Those were the good old days!"

> How is a reddit thread considered the source of truth? ... The forced attrition is no surprise.

I believe because people do not see forced attrition as a surprise, they also believe this post. I agree that we shouldn't take every Reddit post as truth but it makes sense in the culture Amazon portrays. Also there hasn't been anybody that offers a counter perspective into the inner workings (that I have seen). True or not, it would be interesting to see the companies that do practice this and what kind of workplace culture they put forward.

Edit: Formatting.
I disagree. It's a prediction that has been true many times.
Whoa that's crazy! Thanks for the link.
I really like APR. While pooled allocation isn’t always the best approach, it makes a lot of sense in server software, and reduces the risk of many classic memory problems (e.g., I don’t have to worry whether I pair 1000 mallocs with 1000 frees; it’s acceptable to pair 1000 apr_pallocs with a single apr_pool_free).

ASAN is certainly helpful when using classic memory management techniques, but since so much C code uses custom memory management of some kind, it has to handle more than malloc and free.

I certainly hope people improve ASAN instead of abandon things like memory pools. I would consider “malloc and free with ASAN” to be a step down from APR’s pools.
> [Facebook colluded] with Russia to influence a presidential election and install a puppet president.

This is a conspiracy theory, and really diminishes the level of the conversation here.
Yeah, it's an analogue problem and not easy to solve. Hopefully, a manager that did that would get found out when his team was full of incompetent cronies.
Yeah, that seemed like an unnecessary, irrelevant personal attack.

Raise the alarm about what he's doing to privacy, not his social shortcomings.
It's not an odd safety override. An overthrust situation is always dangerous for various reasons. One of the more spectacular is the possibility of liberating airfoils from the engine and shooting them into the cabin.

It's not a self-destruct button, it's anti-destruct limit.

As for the thrust reverser, there are many integrated systems on the aircraft. It's possible that the cockpit detected weight-on-wheels, but the flight mode hadn't yet transitioned for the engine controls.
I meant I want to side load apps on my phone that I don't write that other people make that perhaps violate Apple's rules. Like one that replaces springboard for example. Without having to jailbreak.
On the flip side, that's not how perf work is done in the real world. Start with a simple implementation that's easy to maintain and easy to understand. Run profiling, don't guess. Iterate and make it better.

Devs worrying about big-O cause issues, too, no matter how good the intentions. CS itself isn't harmful, just one of many tools in an engineer's toolkit.
I feel like 95% of the Medium posts I find are some vague attempt to sell. Usually some company trashing a competitor for pages, and then the last paragraph is their call to action to try their new replacement to said competitor.
How?

IMO it is very transparent:

Anyone can invite and everyone can see who invited who. No secrets or murky procedures there?
“They would have the poor be poorer, provided the rich were less rich!”
I see this as a start of a political battle between Apple and Facebook (maybe Google too with their Screenwise Meter app). First Facebook tries to push the limit of what Apple would deem acceptable. Then Apple pushes back and show that it's clearly not acceptable.

Now waiting for Facebook's response.
Even ignoring directly related apps like Messenger, Facebook is the main way I log into a large chunk of unrelated apps on my iPhone including games, food delivery, shopping, etc. Nuking the main Facebook app could cause harm to a huge number of users and third party developers.
Medium has a great low barrier to entry but if you're a developer looking to post your own content or are setting up a site for someone I seriously recommend looking into a static site set up.

With services like GitHub and Netlify (for hosting) and Contentful (as a content editing GUI) the day-to-day experience is seamless, you don't have to worry about security issues like you have with a traditional CMS, and you can make use of amazing tools like Gatsby.js (React based static site generator).

My colleague Khaled made a great tutorial specifically about Gatsby.js: https://www.contentful.com/blog/2018/02/28/contentful-gatsby...

It's no surprise that over and over again, Facebook has shown us that it will stop doing some of the bad things it does only when it's caught red handed. Until then, the employees who work there won't have any ethical qualms and the company won't care much about the impact either. Every time some news like this comes out, the PR department probably shrugs its shoulders and says "What are the users gonna do now? Quit our platform? Where will they even go to?" and just laughs out loud.

If a person were to adopt this behavior, we would call them a criminal. Facebook, on similar lines, is a criminal enterprise that hasn't been punished appropriately so far!

Not at all. I've been in many interview loops in Amazon. The hiring bar obviously depends on the team but it's usually higher than other FAANG without Google

I believe this is what Airbus uses:

> or to only engage reverse thrust once the landing gear has weight on it.

Having reverse thrust depend on a sensor that could fail seems like a poor choice. What if the landing gear don't drop? Is there a situation where you would still want reverse thrust without landing gear?
How about a spice dispenser that measures out the right kinds of seasoning for a recipe. If you are in the flavored rice section of the grocery there are tons of seasoned rice or grain products. Plain rice is much cheaper and probably better anyway. And those products could be threatened by the spice machine. Mexican rice costs about 2.50 but raw materials cost the company only a small fraction to produce it.

Adding value is a good way to have a business objective. If you take something cheap and sell it a high multiples you got something promising.

I agree, the disdain China has for the US and the Tiawan issues and other factors are causing this administration to do some crazy things (it will probably change in 2 years when elections are held again in the U.S.). I mean we (U.S. citizens) are being advised not to travel to China for risk of being detained and prevented from leaving the country (I mean they execute drug traffickers from Canada, pretty harsh).

I didnt think someone as big as apple would consider moving production (and they might not). But given the chilly relations of our two countries and the less chilly relations we have with India it is not to hard to imagine things changing.

Of course. All it requires is some naive (usually older) family members. In this case, my in-laws are in their 70s, and extremely right-wing. They would share stuff from the Nation in Distress group all the time before Facebook banned it. That is just one example; Facebook has been extremely instrumental in providing a platform for disinformation and propaganda. Just because you don't see it in your own bubble, does not mean it is not a threat.
I struggle to find somebody who can justify their favorite framework without using a cliche. Once I hear the cliche I have stopped listening to anything that comes after, because its all bullshit.

Marginalism.

As someone who's managed teams for many years, I think it's really odd to do this stack-rank thing.

A team is supposed to be more than the sum of its parts. People on the team do different things that are complementary. If you've ever watched sports, you know what this means. Not everyone is scoring the goals, someone needs to make critical passes, someone needs to get the ball out of defence, and so on.

That's not to say everyone should be paid the same. Clearly some roles are more rare than others and need to be compensated thus. But it is also true that your star needs someone to carry water for him, and that having the star and the water carrier makes the team more effective than two of either.

So when it comes to letting go of people, it rarely makes sense to try to decide who is productive and who isn't. A lot of businesses wouldn't even operate without juniors on the lowest grades. For instance junior investment bankers make powerpoint slides and financial models. Senior investment bankers, who have long forgotten how to use PowerPoint, take these to customers and get business.

The only times I've let people go is when I've thought the team really doesn't need this person. It's not a question of being inherently productive, it's a question of whether the marginal productivity of the team goes up. And as in sports, sometimes you find it's a star player who needs to go. Sometimes a bit-part player.

But in no sense is there a magic score from which the bottom can be removed.
