If you’re betting on metallurgy to be the barrier to keep western technological advantage alive I think you’re in for a surprise.

It's worked out well for the past 70 or so years. Industrial espionage can only go so far, that's more or less why the Russians dominate the rocket market.

So they have gone back to using the material used to build every other narrow body plane on the market in this size category. I admit, a new design should use carbon fiber, but given that no one else is yet...

The MC21 and C-series use carbon fiber wings and the MC21 also uses a CF wing box. Comac is targeting planes from 20-30 years ago. Even if it were perfectly reliable, it's nowhere near competitive with what's on the market now. If that extra few percent of fuel burn weren't important there'd be no market for the NEO or MAX.

First off, airlines have purchased a ton of E175 family aircraft.

That's the entire point. Without that scale support becomes that much more difficult and expensive.

Third off, COMAC can focus on the Chinese market to start and take it region at a time slowly expanding across Asia.

Yeah they've tried. The ARJ went over like a lead balloon. The domestic airlines haven't warmed up to Comac, and it's highly unlikely the C919 will move the needle much.

From there South Asia and SEA is easy and both are big markets

With a strong anti-Chinese sentiment (Malaysia, Vietnam). Perhaps more importantly SEA sees a lot of short-range widebody service which the C919 doesn't help with.

Russia would welcome it with open arms

Russia would welcome a direct competitor to its homegrown offerings? That seems unlikely for the C919 and unlikely even if we're talking about a hypothetical plane built in a Sino-Russian joint venture. Although why would they partner? Russian avionics aren't going to be accepted internationally, Russian engines are woefully inefficient. Comac struggled with the Ukranian wings on the ARJ. Maybe a carbon fuselage, but are the Russians anywhere near being able to do that?

and then they can take a whack at the middle eastern market

The shrinking middle east market? Emirates/flyDubai (who's got both Airbus and Boeing wrapped around their fingers is scaling back their growth (to put it delicately).

and also be competitive anywhere Airbus and Boeing aren’t really playing that hard anyway. (Africa, etc.)

How welcoming will Africa be as they slowly come to terms with how screwed they are by the Belt & Road initiative? Sure, maybe CCP applies pressure to make sales. That's not going to translate to any sort of European or American success though.

Let’s see Boeing deliver the MAX again first.

I suspect that's not going to happen.

I think it would be easy to win a bet that COMAC delivers C919 to commercial airline customers before Boeing delivers a new narrow body design to replace the 737 family.

Boeing began working on a 737 replacement before the MAX program was begun, meanwhile Comac pushed the EIS target for the C919 back to 2022. As Aviation Week pointed out last year the C919 needs about 33 hours per month of flight testing for a 2021 EIS, in practice they're seeing about 5 hours per month. So, maybe.
In this case it totally is. Your free to not use 23andMe if you don't consent. I do think, however, it shouldn't be buried in the EULA but communicated clearly.

What Every Marketer Should Know
> Does iOS currently use different signature sizes?

Code and data live in the same address space, and the address-space needs of the system are the main input to the basic signature width, so the basic signatures widths are currently the same, and the only difference is TBI.

You could imagine a system where code was always loaded into a restricted subset of the address space and so code pointers could use wider signatures.

> Can I write an application that uses the top bits of data pointers?

Apple's ABIs actually consider the top 8 bits of data pointers to be outside the addressable range on all its 64-bit targets, including x86_64. ARM64 TBI just means that you don't need to explicitly mask off those bits before doing loads and stores. But there are caveats:

- ARMv8.5 memory tagging uses bits 56-59, so you should probably stick to just the top four bits in case Apple ever uses memory tagging.

- IIRC the first ARM64 iOS release didn't enable TBI, so if your deployment target goes really far back, you do still need to mask.

- The ABI for pointers expects those bits to be clear on normal ABI boundaries. This means you need to mask before handing pointers off to other code; on the upside, however, you don't need to worry about those bits being set when you receive a pointer.
I second this. Things like the lack of multiline messages is something one would expect out of the early 90s.
Read hunter forums debating MSRs vs. bolt-action rifles. You'll have no trouble finding hunters certain that MSRs are overtaking traditional hunting rifles simply because they appeal to undisciplined, unserious weekend warriors who are drawn to their military look-and-feel, and that arms manufacturers feed into that because traditional hunting rifles also last forever and the industry needs people to get on a continuous upgrade cycle.

You haven't seen me anywhere advocate that we ban anything, let alone a particular semi-automatic weapon by name; in fact, the root of this long subthread is a comment from me saying the exact opposite thing, that wood-stock ranch rifles pose exactly the same problems as black rifles.

What I have a problem with is the faux superiority gun maximalists dress their arguments in, along with a culture that elevates a simple machine designed to be serviced by teenagers outdoors in the rain into a solemn, secret brotherhood, as if being able to remove the fire group from an AR-15 meant these putzes had the mechanical aptitude to swap out a car transmission or even replace a hot water heater. The technical details behind assault weapons are far more learnable than almost any other technical issue we regulate without issue.

I stated my policy preference elsewhere on the thread: give up on national firearms policy, back down on the maximalist Heller interpretation that says MSRs are off the table for state regulation, and allow states to license (on a presumption of must-issue basis) all semi-automatic long guns if that's what their citizens decide they want to do.
Huh? What's the point of deploying AI with the same shortcomings as humans?

>I'm inclined to believe this data because I trust MIT

Really? After the missile defense fraud cover-up at MIT Lincoln Laboratory that was exposed by Prof. Ted Postol or the deliberate "anonymization" of donations from convicted child rapist Jeffrey Epstein (both at the direction of President Rafael Reif) ... or how about the former deputy dean of the Sloan School of Management, Gabriel Bitran, who ran a $500 million hedge fund scam for which he's just finishing up his prison time in a federal penitentiary down in Philadelphia (after narrowly escaping charges that he sexually assaulted one of his secretaries a decade earlier). The Sloan School is the same MIT institution that bestowed a prestigious entrepreneurship prize on Brandon Wade, who has recently spoke on campus about what it's like to start one of the largest and most successful online prostitution businesses in the world, on which some MIT girls apparently advertise their services (supposedly to help cover the sky-high tuition that funds the bloated MIT administration).

It wasn't supposed to be best or worst cases, it was just supposed to show that living under your means do matter and that someone with a fraction of the disposable income of a high earner can still earn more in the long run by saving regularly, obviously a high salaried person with the same mindset will earn even more but that's beside the point. The point was that cash flow management do matter.

I could have made a case with a even higher earner living even more lavish, racking up credit card debt and payday loans, buying stuff on installment ending up even worse with debt interest eating up much of the cash flow, here I simply compared someone living under their means with a higher salaried person living at their means (never beyond).

It's a bit weird that the map also includes a few lines that aren't subway lines. For example, on the DC map there are a few bus lines listed as well as the light inter-city commuter trains. Its also not clear at a glance which is which when looking at the map. While the extra info is nice to have, people are going to be looking around for subway lines that don't exist.

The maps really need a legend. The font is also way too small. If this were posted in place of the regular metro map in the subway, I'd have to stand up and walk over to it to read it. Older people would be pulling out their magnifiers.

News organisations should not be legally bound to take the moral high ground.

While we can debate about what they should have done (and I agree with you in this case) it's difficult to write laws to define what constitutes a moral vs immoral publication or what is news-worthy.

Consider what would have happened in they had a Clinton-Lewinsky sex tape. Could they have released that to refute Bill Clinton's denials?

It quickly gets very difficult, and I would rather have a totally free press than one that has to worry about running afoul of moral news laws.

An absolute path is a valid path on the filesystem. But the compiler should be searching according to its implementation dependent search paths, when doing <>. Not prepending the searchpath (and not rejecting) for absolute paths is an implementation choice I personally think is wrong for a C compiler. But it may be able to do so I guess as you can also do "..".
Sure it would if it's necessary to provide some plot armor. Napoleon gets hit by shrapnel and spends an episode with some bandages decoratively draped over the wound while commandeering his army from the front lines, even though the severity of the wounds should confine him to his bed. The next episode he doesn't even need the bandages anymore.

Realistic medicine in fiction usually doesn't fit the narrative, same as realistic anything, so you get symbolic medicine instead. I assume the show in question also features unrealistic martial arts combat that only serves to display the protagonist's superiority rather than showing you how to actually win a fight.
Physical maps of subways systems in Paris, London and other cities
There are options other than "put your entire infrastructure on Amazon" and "hire someone fulltime to manage your physical infrastructure".

Unless you have some truly massive amount of hardware (in which case it's _definitely_ cheaper to hire someone than pay Amazon), you can generally just set it up and forget about it save for periodic maintenance and emergencies.

So what you really need to pay for is the time of someone who can do these things for you and funnily enough, such a service exists. I believe it's common in the not-startup world: a managed services provider (MSP).

And in the end this really depends on what the business is actually doing. AWS is _really_ price inefficient but in particular for bandwidth. If you're doing anything bandwidth-heavy like video, images or backup, you want to keep the hell away from any kind of cloud.

Highschool me fucked up pass and exposed a lot of data. It was entirety my own fault, but there are footguns if you don't fully understand the model.

Essentially, I accidentally publicly exposed my private key. I thought I was clever for writing a Python script to dump all my passwords and then re-add them after setting up pass with a new key.

A year later, when I accidentally deleted my private key (reformatted laptop, phone bricked before set laptop back up), I spent a few hours trying to figure out if I made a mistake that would let me recover my passwords. I was very motivated :)

Eventually, I realized that since I'd been using git to sync pass between my phone and computer (the recommended setup) I could access versions of my encrypted data for every account more than a year old and decrypt them with the private key I leaked. I got back almost all my data.

Luckily I was using a private git repository for defense in depth, but many guides recommend a public reposity because they say gpg is very strong.

It all works, but only if you don't do something dumb like I did. Now I'm on 1password and happy knowing that experienced people are paid to make it and smart security researchers like Troy Hunt (of haveibeenpwned fame) have said it's the most secure password manager they've looked into.
We’ve now seen three products released since the creation of the “Pro Workflow Team” (iMac Pro, 16" “magic keyboard” Macbook Pro, Mac Pro). This team apparently consists of "artists and creatives who came out of the industry, in the video, audio, and 3D space, [... and] system architecture people and deep computer scientists that partner with the first group,” all working alongside the product designers.

The iMac Pro was fairly well received, and the 16" Macbook Pro is near universally acclaimed. Early word on the Mac Pro is that it’s great for folks who need that kind of lift. It sounds like this plan is paying off.
So does property value. Occasionally one, or both, of those goes down, too.

The criteria the Brookings paper used to determine eligibility doesn't make sense. Specifically this bit:

"Looking next at the remaining top 20 metro areas with the most innovation sector jobs, only those that saw population or real GDP growth slower than the nation as a whole since 2010 are considered eligible to become designated growth centers. By dint of that, cities such as Raleigh, N.C., Boston, San Francisco, Seattle, Austin are set aside because they are already self-sustaining superstars. They are safe bets for any new tech graduate looking for a job or any tech firm looking at add a few hundred jobs somewhere. Allowing these places to be eligible would simply reinforce existing spatial imbalances."

This decision disqualifies growing Sun Belt metros including Austin, Houston, Dallas, and Atlanta from inclusion, specifically because they are already growing. The result is a list that is biased towards metros in the northeast and midwest, which are shrinking for a variety of reasons, not strictly due to job opportunities.

This has two problems:

1. It sets the program up for failure: Targeting shrinking metros means that the policy intervention needs to offset existing decline before it can demonstrate any positive growth. This is not easy! There are lots of public programs already targeting these metro areas (particularly state-level programs), and they are still shrinking.

2. It makes it very unlikely that the program would develop a new "superstar" tech city comparable to NYC, because you've already excluded the most probable candidates.

Adding some regional balance for fairness and (valid) political concerns is a good idea, but a program that proposes to subsidize growth in Chicago and Minneapolis while excluding Atlanta, Dallas, and Raleigh-Durham seems neither fair nor sensible.

Sleeping 9 hours a night may raise stroke risk
From article 4:

(12) ‘personal data breach’ means a breach of security leading to the accidental or unlawful destruction, loss, alteration, unauthorised disclosure of, or access to, personal data transmitted, stored or otherwise processed;

So it seems that a ransomware attack is considered a breach - as it should be - and neither exfiltration nor disclosure is necessary for that to be the case.

Any sort of access is a weapon in the hands of a malicious hacker. Penalties for allowing it to happen are weapons in the hands of those trying to do something about it.
You obviously didn't read her blog post where she stated the following:

"This kind of code change happens all the time. We frequently add things to make our jobs easier or even to just share hobbies or interests. For example, someone changed the default desktop wallpaper during the walkout last year so that the Linux penguin was holding a protest sign. The company has never reacted aggressively in response to a notification such as this in the past. It’s always been a celebrated part of the culture."

I have done far more buying though the web sites of B&M retailers this season that I have in past years. I no longer trust Amazon for name brand electronics or anything to be ingested. It seems I'm adding new categories of distrust every week.

Just today, I wanted a new flash drive but didn't need it urgently. I checked Amazon to get an idea of fair pricing then looked at Best Buy and found one that looked good on sale. I went to the manufacturer's site to verify the specs and found they had a price 33% lower than the next closest retailer. Win.
That is unfortunate. Huge turn-off.
