100% facts. They do.

In prior roles, I've worked at 2 of the largest US airlines that have gone through mergers. There are lots of hard-coded letters in decades-old code that help identify what's mainline, regional, and OA (other airline). We're talking everything from reservations (booking) to revenue recognition (flight departure).

It would be no simple feat to upgrade the tech stack. Hell, some of the mergers are still lingering within the systems because airlines wanted to complete it quickly for the passengers. The backend, however, has band-aids all over the place.

Spotify has a list of recommended distributors [1]. The first one on the list, DistroKid, charges $22/yr for unlimited uploads to Spotify, Apple Music with the artist keeping all royalties[2].

$22 is not free but is very reasonable.

Is this statement accurate? "Airhart Assist provides a combination of (car like) cruise control as well as automatic rudder control." If correct, does it do anything else?

Yes, 25% of current ownership seems high to me. Most homes have been owned for decades. But percent of new purchases is a leading indicator of where the market is heading.
Not to be negative towards my musical friends, but the bands that can make a living today are often putting out incredible art.
They’re called science denier, which isn’t much different, and “flat earther” has a significantly negative connotation as well. I think the term matters less than pushing things into the appropriate context: leave religion a person choice but reinforce the secular world as following rational principles.
I too am a paying customer. Surprisingly -- at least to me -- it's easy to do with Microsoft's Edge browser on iOS. I use it as default on both iOS and macOS.
> In the US, trips that are 50-300 miles are almost all done by car because that distance is too short for commercial airlines and too far for public transportation.

About once a month, I make a 90 mile (180 round trip) drive to see family. The drive is usually 90-100 minutes.

Would GA really save time? It's half an hour for me to get to a GA airport, and then roughly half an hour to get to my family from the other GA airport. And then, we'd need to arrange ground transportation.
Haha, I mean they could easily survive as separate companies. Not that separating them would be easy.

How about CO2 emissions?
If there's no health reason not to, try a different food. A fish based one maybe. Give a little bit at first to avoid upsets. If you keep two types in stock you can switch frequently rather than just feeding the same one and switching when the bag is empty.

They probably don't have the abstract concept of purpose, but they have various drives, like we do, some of which may be unsatisfied. May be worth reading a few books. Catwatching by Desmond Morris is good, but quite old now.

However I think even the wild cousins sleep 16 hours.
Even if not explicitly conditioned, which I don't believe came out as being the case in this case, there's still an inherent motivation. Google will pay more for a default on an OS where it's hard to switch the default than it will for a default where it's easy to switch away. Google might pay $20 billion for defaults on iOS as-is where 99% of people stick with Google, but if Apple started asking users if they were sure and offering alternatives and Google only remained the default for half of people, they logically would only offer maybe $10 billion to remain default on the same actual terms.
ironically, I find that more interesting.
Web tech is horrible, but creative programming is great.
The provider side skates by with very little scrutiny in the US, when they make more than anywhere else in the world while also crying poverty and whining about Medicare/caid reimbursements. They're gonna have to figure out how to make it work with those rates because commercial spending levels are unsustainable, and the rate of medical inflation is unsustainable.

I haven't said anything about "more government intervention". Hospitals, doctors, and device makers are making bank, and are still greedy for more. They are the ones causing medical inflation higher than general inflation, it is not a fact of nature. It's on them to figure it out and to learn to live within a smaller budget.
Rust: The Programming Language?
No, but it means there’s a consumer safety issue rather than a problem with the standard just as someone selling contaminated meat does not mean that the food safety labeling laws are broken.
Great, thanks for this link, will dig in more.

There is a lot of differences what clearly separate the desings, but you didn't even try to address these.
> I don't feel like this article illuminates anything about how noexcept works. The asm diff at the end suggests _there is no difference_ in the emitted code.

You are absolutely correct. The OP is basically testing the hypothesis "Wrapping a function in `noexcept` will magically make it faster," which is (1) nonsense to anyone who knows how C++ works, and also (2) trivially easy to falsify, because all you have to do is look at the compiled code. Same codegen? Then it's not going to be faster (or slower). You needn't spend all those CPU cycles to find out what you already know by looking.

There has been a fair bit of literature written on the performance of exceptions and noexcept, but OP isn't contributing anything with this particular post.

Here are two of my own blog posts on the subject. The first one is just an explanation of the "vector pessimization" which was also mentioned (obliquely) in OP's post — but with an actual benchmark where you can see why it matters.
https://quuxplusone.github.io/blog/2022/08/26/vector-pessimi...
https://godbolt.org/z/e4jEcdfT9

The second one is much more interesting, because it shows where `noexcept` can actually have an effect on codegen in the core language. TLDR, it can matter on functions that the compiler can't inline, such as when crossing ABI boundaries or when (as in this case) it's an indirect call through a function pointer.

`cmd+?` works, but it's visually quite hard to follow. The raycast version looks much more like an universal command palette, and supports fuzzy matching.

> as most trains start and stop in city centers while airports are sometimes very remote from the cities.

You write that as a negative, but for me that's just an even bigger bonus. The only thing I want from a city center is how to get out of the city center. I never actually want to go there.

I have not personally noticed much difference in commute costs plane vs train. Car trips, taxis, and public transport, have all been around the same time and cost to both. And the plane tickets I've looked at have been at all kinds of hours, early, middle of the day, and late. Exactly the same with the train, there's no specific pattern. (Obviously this is very specific to the location.)

You have a point with the food, it's easier to bring on a train - luggage as well, but then again the plane is so much faster you don't need to bring as much food.

And I do factor in wait time for an airport, very short trips are faster and cheaper in your car, longer trips are better in a plane. The train just doesn't really fit in anywhere - it's the same speed, or slower, than a car, and less convenient. (Even if the train is physically faster, getting to/from the station adds so much time the car works out faster.)

I book a lot of Spirit flights, and not only are they cheaper than a train, they are even cheaper than a bus! Every one in a while I go back and check all 3 options, and the plane and (occasionally) car win every time.

If you want people to take more train trips they need to cost 1/10 of what they currently do, or at least be 5 times faster. Without that, well, people just aren't going to use them.
All registers are basically always treated the exact same in OoO-land (though on x86-64 for some instruction forms it can add an extra byte of instruction encoding if there's some operand in r8..r15).

But there's still a massive amount of performance tuning. Some fun examples being how Haswell can only do one FP add per cycle, but two FMAs, so you can sometimes improve throughput by replacing some 'a+b's with 'a*1+b' (at the cost of higher latency). Or how, on older Intel, three-addend 'lea' can execute on only one port (as opposed to two for two-addend 'lea', or 3 or 4 for 'add') and has 3-cycle latency (vs. 1 cycle for two-addend; so two back-to-back 'lea's have lower latency than one three-addend one), but still uses only one port and thus can sometimes be better for throughput.
They could shine a very bright light into the fiber and see which tree lights up on the other end, at night :D

That's fantastic. Are they published somewhere?
Usually any trend is the result of a confluence of factors. There are probably a dozen reasons why rents are up in any particular city.

It seems that constrained supply and consolidation in real estate companies are two causes. Both cause upward pressure individually, but together have an even more powerful effect.

This is not the courts problem. Google needs to solve this before the split.
The petition is worded generally. Just says video games should stay in a working state.

The comment above talks about a remote killswitch in particular, which suggests a portion of the game that doesn't reasonbly require online access is being disabled. Anything multiplayer understandably might not work forever. If The Crew had a singleplayer mode that got disabled (idk, never heard of this game) and was a one-time purchase with no refund, that's pretty scummy imo. Even then, if that were outlawed, that'd push them to put everything online instead of giving a local copy out at all.

Also, I know Steam updates cannot be disabled or reversed. GTA IV is a local game, but they released an "update" that deleted some soundtracks. Sure you can run Steam in offline mode, but not if you have any multiplayer games in your library.
They have easily improved my coding productivity by 40%
This is a good start but all the tech giants need to broken up. Their size alone, and their access to capital, lets them do any number of anti competitive things. The deals/partnerships they make, the acquisitions, the bundling (like Teams and Office), loss leading, reliance on network effects, patent portfolios / giant legal teams, all of it. There isn’t really a great innovation landscape when these companies can just copy your idea and go scorched earth. We also need to regulate some of their products as general public utilities. For example there is no reason YouTube, a basic video hosting platform, should have content that only Google can train AIs on. I really hope Harris and Trump double down on Lina Khan’s direction and not succumb to corporate bribery…I mean lobbying.
The issue is that there is no direct fix.

It depends instead on the overall health of the Internet.

We are moving away from open commerce and into walled gardens. Once Google makes deals similar to their Reddit deal with Meta and Bytedance, it's going to become basically impossible for an upstart search engine to index anything competitively.
What are you trying that other companies have not tried? Ballistic parachutes are available on several aircraft.

If you load up on redundancy - well, electronics redundancy it seems, since the rest of the aircraft seems to be a Sling TSi - you increase cost and weight, decrease speed and useable load, and so on, and now your aircraft costs $800k-1m and $100-150/hr to operate. How many new clients that would not otherwise have gone into GA will you attract? Dual navigation is already commonly available. So what are you doing different that YC was interested in paying for?
From the paper, seems like they are using RDMA to/from video cards, skipping the nic.

> * These transactions
require GPU-to-RDMA NIC support for optimal performance*

Remarkably consumer computing actually has similarly found reason to bypass sending data through the cpu; texture streaming. DirectStorage and Sony's Kraken purport to let the GPU read direct from the SSD. It's a storage application instead of NIC, but still built around PCIe DMA-P2P (at least the DirectStorage is I think).

Table 2, network stats for 128 GPUs is kind of interesting. Most topologies such as AllGather and AllReduce run with only 4 Queue Pairs. Not my area of expertise at all but wow that seems tiny! All this network, and basically everyone's talking to only a few peers? That's what it means right?

The discussion at the end of the paper talked about Flowlets. The description makes me think a little bit of hash bucket chaining, where you try the first path, and if latter a conflict arise or the oath degrades, there's a fallback path already planned. Like there's would be a fallback chained bucket in a hash.
Maybe they will allow a level-playing field and allow bids like in a marketplace?
Thanks for the reply. This is a super interesting project and I wish you great success. As a builder/pilot I have so many little questions, mostly around how you're making all the trade-offs and decisions that pilots make based on the situation in the air (leaning for cruise / power, climb and descent rates, weather-related decisions, switching tanks, and so on). Do you anticipate equipping / certifying the airplane and systems for instrument flight? Is your entire avionics package custom, or do you use some off-the-shelf?
It was still a common occurrence for google to display incorrect results that weren't common wisdom.

I had tons of such experiences. One I remember was searching for "healthy body weight for x of age y" where x was man,woman and y was my age. Google said 50lbs higher than I expected. I clicked through to the article. The article said the average was this high number, not a healthy weight.

Microsoft's internal memo: So Long, Intel (1992) [pdf]
In your case, you do start to approach the point where time-wise it's about equal. But, 30 minutes to your nearest GA airport is on the long side, most people (300M) live within 15 minutes of one (don't have a direct source for that--it's based on analysis we did of locations of airports and population densities)
if that’s true, expect another antitrust lawsuit soon after.

Using market dominance to enter other markets is the problem…

Myers Diff Algorithm is 40 years old: can it be improved?
The biggest advantage is simplicity. To log an object in your application with OpenTelemetry, you either need munge your data to adapt it to their spec or rewrite a lot of your application code using their span abstraction. In contrast, with Telemetry, you can ingest any object you already have in your code as JSON with a single line of code and start analyzing the data immediately. Moreover, our SQL API makes it easy to integrate this data into your product or internal dashboards, unlike tools like Mixpanel or Amplitude that offer similar ingest APIs but lack APIs for SQL querying.
There is no inconsistency.

The first quote is meant to highlight that commercial planes have autopilot while e.g. Cessnas do not.

The second quote emphasizes the importance of training despite autopilot.

There is no inconsistency in pointing out that commercial planes have auto pilot while acknowledging that it would be nice for non-commercial planes to also have auto pilot even though training is important.
The paper excuse to justify the TX move is further proof that the Twitter purchase was on behalf of Putin's alt-right disinformation ecosystem.

There are problems with prop 13 (being a bandaid solution to appease the senior/older tax base) but schools in the US are very well funded, when you look at per year/per student in k-12, usually up there with countries like Switzerland and Norway. Its how the money is used that is the problem.
As long as it’s an ongoing relationship nothing needs to be said. Apple knows that if more users swap away from the default then the default setting is less valuable.

I’m not really sure how you fix it. Considering it specifically calls out being the default option on iOS, we can assume that’s going to change. However, I could also see Chrome’s market dominance challenged. Maybe they’ll be forced to somehow split that off and Chrome will need to be funded through some combination of donations or selling its own ads/data.
> The claim that "supply and demand" somehow do not apply to housing as they do most goods is an extraordinary one, and extraordinary claims require extraordinary evidence.

The extraordinary evidence is the proof of collusion - which we have. That's all that it takes to corrode away the basic tenants of a free market, and it's why collusion is policed the way it is. It is, frankly, a mistake to play down the impact that collusion between landlords has on the rental market.

"When competitors agree to fix prices, limit production, or engage in other forms of collusion, the natural balance of supply and demand is disrupted. This disruption typically results in higher prices for consumers, as the competitive pressure that usually drives prices down is absent."

"Collusive practices can also lead to a misallocation of resources, as they distort market signals that guide investment decisions. In a competitive market, prices signal where resources should be allocated to meet consumer demand most efficiently. When prices are artificially set through collusion, these signals are corrupted, leading to resources being channeled into less productive or less needed areas."

Congratulations. I already told you I test my programs. The discussion is about expending brain power and time writing hundreds of lines of code to test the intended user-facing code, which, in my opinion, is just dumber than a bag of hammers.
we won't want to lower the bar in terms of the pilot's ability to stay safe. But we do want to lower the barrier to entry so that more people can learn to do it, do it safely, and enjoy all it's benefits.

Once when I was a child I was at the zoo watching the chimpanzees and one of them reached behind itself, crapped right in it's own hand, and flung it at my head. It exploded on the glass right in front of my face. I was startled but then we both shared a laugh.

Right now that chimpanzee is better than you.

So when using these intrinsics an Intel Core i7 can do 30 GB/s but the performance check linked above (by isosphere ) says only 300 MB/s, i.e. 1%

Something is amiss here.

If a CPU can do 30 GB/s then a CRC check should not have any real performance impact.
Why would anyone bid for being the search engine in a browser with <4% market share and falling? Everybody will want to be on iPhone/Safari, Android/Chrome, and Windows/Chrome or Edge.
In a very competitive market, reducing quality slightly could drastically reduce revenue.

E.g. if there were two brands of apple at the grocery store and one started putting a tiny worm in each apple, you would expect the worm apples to lose nearly 100% of their revenue.

Seeing the Earth from a bird’s eye view is a historically speaking very recent privilege only a tiniest fraction of humanity was able to enjoy. If you want to get society-wide shifts of perspective about the Earth, you want more people to experience flight (and even spaceflight), not fewer.
The FrankenPHP binary also needs a daemon to manage it, which is why the docs recommend using Docker. So you end up with Docker (or SystemD or whatever you prefer), managing Caddy, which is in turn managing PHP. This is because the server which ships with PHP is documented with a big red warning that says something to the effect of "don't actually use this in production, this is just a dev server" [1]. Node's built-in web server is production ready, so you can safely cut out the reverse proxy middleman. I don't actually have any major qualms about the FrankenPHP stack, I was just trying to intuit what the original commenter meant when they said "standalone server".

There are systems that can target jammers, like an anti-radiation missile (ARM): https://en.wikipedia.org/wiki/Anti-radiation_missile. Advanced systems like ARMs use complex sensors and algorithms to determine the location of the emitter before guiding themselves to its location. That allows them to hit an inactive radiation source and avoid terrain, but it requires sensors that are too expensive to use on quadcopter-type drones.

As far as I understand you can't simply follow the emitter signal because the jammer can easily take countermeasures. For example, putting the jammer inside a building or vegetation would prevent any unpiloted drone from causing any harm. Even if the jammer was exposed, cycling it on and off every 30s would still effectively interfere with flight but prevent a signal seeker system from reliably finding the jammer. Plus, many drones don't have the range to reach a jammer.
