Predatory pricing is a component of anti trust but a very difficult one to prove legally. One must prove that by giving consumers a cheaper product they are being harmed. It's an interesting conundrum.
> The weird idea that only the "super-privileged" can do this is just flat-out wrong.

It's not that YOU HAVE TO BE super-privileged to be able to quit your job and take a whack at the start-up lyfe, it's just that you are much more likely than the average person to be super-privileged.

That's how stereotypes work.
I was happy to make $3-$4 in MRR from a 4 minute YouTube video. It took some months to hit 10k views to enable monetization, but monetization for that amount of work was great.

Then Youtube said fuck you. Your 1-video account doesn’t have 1000 subscribers, no more monetization for you!
Same, it's been great. I've mostly used it for renting large homes in Tahoe.
There's a few significant differences here. This is a printf that only happens in debug mode; dbg is something that takes an expression, returns that expression, and will print out its filename, line number, and a pretty-printed version of the value.

For an example of how this plays out, I had some code:

let x = y + z;

I wasn't sure what y was, so I was able to

let x = dbg!(y) + z;

this is much easier to insert into (and remove from) existing code. Plus, you don't need to write the formatting code.

Basically, what you posted is in the same genre of thing, but is very different in a lot of meaningful ways.
Of course. Why not?
Possible? Yes. Scalable? Not over time in my opinion.
I love Cold Turkey! The only issues I’ve had with it are when I find little back doors around the blocks and don’t know how to block those. But those are very few and far between.
After the study is concluded, won't they get the non-blinded (still anonymous) version?

During efficacy/side-effect analysis you should definitely use only blinded data. After confirmatory statistical analysis, it seems reasonable to go over the data in an exploratory pass to possibly discover/hypothesize why/when/how the medicine works/fails/interacts. Or do they just get the aggregate report?
This is the first incident I've heard of that seems concerning, but admittedly I've not followed the matter closely. I've heard they had some incidents on the pad, or the one they crashed earlier this week, but neither of those concern me since failure in those scenarios is obviously something they plan for (nobody would be nearby.)
The debate of electing competent politicians is pretty old. Plato criticized democracy and advocated for rule by wise philosopher kings. In the 1900s it manifests as a debate in Europe where communism gives it a go. In more modern times, Singapore is more on the side of “meritocratic rule over people” than not.
The value is that the developer doesn’t reasonably have the context necessary to make the call whether or not, over time, the issue is worth continuing to invest time to resolve.

Not that they couldn’t make the call if they had all the info, but the time required to gather and understand all the context would be a second full-time job.
This was the second largest "money left on the table" from an IPO. Jay Ritter's document shows how much AirBNB could have picked up if they had priced their IPO appropriately.

I remember trying to set up a PVR and getting pretty far using mpv and at. The system worked as long as it was left on. rtcwake was the bridge that was too far: Upon waking, recording started but ACPI errors occurred soon after, culminating with ivtv reporting the encoder had died. I never got past that stage, but it was a worthy try - and I learned that some bugs ain't never going to be fixed. Edit: It was an Arch setup from about 5 years ago.
My understanding is that these reactors are designed to have a lot of passive safety features (e.g. if all operators walk away the reactor will cool itself and go sub-critical), so quite the opposite of what you are claiming.
They will churn through new customers who get bitten by this until they come up with controls/features that prevent it. Instituting those will increase the price making them less competitive and opening the door to others.

Its quite amusing how much the gig economy is hyped up but besides the initial surge of excitement, it just settles down and looks like the industry its trying to replace.

But I'm a pessimist. Maybe they will use the infusion of cash to invest in something truly groundbreaking. But I'm staying far far away from making any investments in them.
I'm a devops engineer. So not very related either!
I agree with you. Spend enough time in an ecosystem and you'll eventually find a need to interact with most of its features.

My experience in Rust has been pretty positive. I'm writing a new book on systems programming with Rust and, as a result, have spent a great deal of time digging into the internals of libraries, the compiler. The compiler is, by far, the most surprising because it's allowed to use nightly features in new and interesting ways. Everything else, when I encounter something new to me, I'm able to understand from the Rust documentation. The key differentiator with C++ is, I think, the focus on documentation and ensuring that new features are explainable in a simplistic way. This helps make new features introduced into the language jive, to my eye.

That said, there are areas of the ecosystem _outside_ the language that are hard to keep up with. The future notion in Rust used to be like that, before Future was included in the base language. That's tricky but, again, I think Rust strikes a good balance here: conservative about content in the base language, enthusiastic experimentation in the ecosystem. It's possible that this'll break down some day but it hasn't yet and I don't see it as happening soon.
Hi, I'm the journalist who wrote the Quanta article. Scott Aaronson's Busy Beaver survey paper provides a function for calculating the total number of possible (2-symbol) Turing machines with n states: T(n)=(4n + 1)^2n. When n=2, T(n)=6,561. According to an email I got from Aaronson, this "allow[s] the possibility of halt states."
well anecdotes are anecdotes. I've had one in this line for years with no issues. I also had a parrot zik 2 which was all metal and way more expensive and it was generally worse.
We completely agree here. If ARM desktop becomes mainstream there will probably be some kind of abstraction layer needed at this level that doesn't really exist at this moment. I'm fairly optimistic that it will happen when it's really needed though.
This is usually true but not always. I attended an economics program with a terminal master’s offering, and we spent a year and a half as master’s students before moving on to PhD work.

>Slack was perfectly capable of remaining a stand alone company.

It's possible that Slack's company insiders (founders, C-executives, investment bank advisors, etc) ... all concluded that continuing to compete as an independent company had a more risky outcome:

https://www.google.com/search?q=slack+not+profitable

In other words, let's give the benefit of the doubt and assume all those folks above are above-average intelligent and can use Excel spreadsheets to model user growth, revenue growth, expenses, new products in the pipeline, "what-if" scenarios, etc.

Also found a recent related HN thread: https://news.ycombinator.com/item?id=24422092

EDIT REPLY to >"It seems like you stopped reading before my last sentence."

Yes, I read that but a healthy business needs to be an ongoing concern and _profitability_ is part of financial health. E.g. Blockbuster Video went from having a market cap worth billions to being worth nothing because of competition from Netflix. Blockbuster went from being profitable to losing money. In one way, Slack is even worse than Blockbuster as it has yet to turn a profit.

Setting your snark aside, what justifies your confidence about Slack's possible independent future more than the company's insiders who have all the internal metrics and private financial data to analyze?

I remember that story. I don't think he ever got it working. There's a lot to getting a real mainframe running, starting with some onerous licensing terms for the software. And the cost to power one would be ugly.

There were some actual 'personal mainframes' made by IBM. The PC/370 was a PC or PC/AT with a set of ISA bus mainframe processor addin cards. The PC became the I/O processor. The PC/390 was a later version based on a PS/2 running OS/2. All long obsolete now.
The battery is actually really easy to replace as it and the screen are the most common replacement(s). Remove the screws at the bottom, break the glue down, and unfold. Access to the screen and battery connectors are right there on top of the logic board. It’s so the service techs at the store can do it quicker. Anything else, they just give you a new device and ship the old one back to Apple.

Previously (think iPhone 4S and prior), the phone opened from the back. So a screen replacement necessitated deconstructing the entire device.

Could it be more accessible? Most likely. They could put in removable batteries (like older phones had), but they’ve chosen not to (presumably for space reasons (internal batteries take up less space)), and it seems the entire industry followed. But just because they’re not easily replaceable, doesn’t mean they’re not easily serviceable. It takes a bit, but an experienced person can do it about 30 minutes or even less. iFixIt’s guides help a lot here.
In addition to what Steve said, note that the rust playground includes support for the most popular crates.
In case anyone else was wondering how having the molten fuel pour out of the reactor is safe - it is designed to pour into a container with criticality safe geometry to stop fission:

"in an emergency situation [the fuel] can be quickly drained out of the reactor into a passively cooled dump tank. MSRs designs have a freeze plug at the bottom of the core—a plug of salt, cooled by a fan to keep it at a temperature below the freezing point of the salt. If temperature rises beyond a critical point, the plug melts, and the liquid fuel in the core is immediately evacuated, pouring into a sub-critical geometry in a catch basin. This formidable safety tactic is only possible if the fuel is a liquid." [1]

Why would the amount other people in my industry make have an impact on what I can afford? Much less whether I'd put up with a little discomfort for an extra $3k in my pocket.

Also funny how you yourself come up with the ridiculous salary of $500k, something ~nobody here will ever make, as the amount that finally makes $3k sound trivial to you. I agree with that much. That's the salary that would make me finally consider paying $3k for leg room.

The best channel imo for side projects is word of mouth virality.

You need to design wom mostly through features. I spent a lot of time learning what makes people talk about products.

You need to use triggers like a special feature that your user will talk to friends about or a cue to enable user to share a story through app with others.

Maybe someone has already pointed it out, but Beats pro over ears are $400, are metal construction, weigh 405 grams (heavier than the AirPods Max), aren’t wireless, and I don’t believe they do any of the clever noise cancelling or contain as much hardware as the AirPods Max.

Sure, the beats pro are aimed at a different type of user but when comparing the two products is $550 really that much of a surprise?

I thought they’d come in cheaper, but on reflection pricing them lower competes with Beats (other than the aforementioned pro model, the Beats Studio3 Wireless Over‑Ears are $350)
Who cares, $600 every 5-10yrs seems fine to me. These are computers on your head. I don't mind replacing the whole unit. But you don't even have to replace them entirely...Apple will replace the battery for $79. So if after 5-10yrs, you wanted to get the battery replaced, you can.

It's almost like people on HN have never bought noise canceling headphones - none of the top models have user-replaceable batteries.

I think you're conflating a VIP getting favorable treatment to your family getting normal treatment. I imagine that other people who went to the same places your family were seen at recieved other treatments if they had worse presentation. If your family worsened they should receive other treatments as well. Hopefully they will have a mild version and fully recover, and if they don't, and nothing is done, someone needs to step in on their behalf and escalate things.
Good question. From our perspective the issue is whether the discussion here gets snagged on something controversial (sensational, etc.) that is less interesting than the main topic. If there's any such snag in the title, the thread will tend to fill up with shallow comments that are reacting just to that. We've learned that when such title objections start appearing, it's best to sand away the snag.
> so it's unfair to assume without evidence that they incinerate them or bury them in a landfill.

It isn't an assumption without evidence. It is an assessment based on a detailed breakdown of the product, a knowledge of the generally understood state of the technologies involved in reclamation. This isn't the random opinion of a shop owner. iFixit has a detailed breakdown and assessment, and they are generally considered experts in the field. What is unfair to assume without evidence is that Apple has some sort of super secret tech no one else knows about to repair them. That is simply a claim without evidence.

>Considering that Apple's battery service fee is $49 per AirPod, that tells me that the residual value of a failed AirPod (a single one, not both) is $99.50 - (depreciation) - $49, so $50.50 in the best case, and almost certainly nonzero in the worst case.

Airpods with Wireless charging case: $159 Retail. Wireless Charging case: $79 Retail. Assessed retail value of Airpods: $80 ($40 each).

Apple replacement of damaged Wireless charging case: $69 ($10 discount off retail). Airpods: $69 each ($30 more than they cost new retail).

Apple “battery repair” of Wireless charging case: $49 ($40 less than retail). Airpods: $49 each (again, $10 more than new retail value).

Given this, there is absolutely no evidence that the Airpods have any reclamation value to Apple and they are just selling you a new ear pod for more than you paid as part of the original product. Apple makes more money per unit on “battery repair” and damage replacement than off the original purchase.
Don't forget CICS (OLTP component). But spot on...a mainframe is an ecosystem, not a language.
My father in law has terribly bad hearing. He often watches TV with headphones on. I could see him wearing these with the volume cranked and transparency on so he can hear when other people talk to him.

IMO transparency mode is perhaps the most interesting thing about these and the AirPods Pro.

Posting for a friend at knowable as their social media person is on vacation.
I live in a top 10 US city (based on population), and it seems to be as you describe - generations of family living nearby, grandparents, etc. always around to help with the kids. Weekly (at least) family meals, parties where the whole neighborhood is invited, etc. I grew up knowing most of my friends' cousins and grandparents because they were just always around. Even today, I know my neighbors' kids and nephews because they live close by, too.
What the heck are you talking about? The most popular noise canceling headphones are the Bose QC35 and Sony WH1000XM4.

Neither of those have user-replaceable batteries. They haven't for years.

And if you wanted to replace the batteries on the AirPods Max, it's only $79. If you can't afford it, don't buy them.
Thank you. That's very useful feedback. Our bot blocker was changed this morning causing that. We've now fixed it. So try again:

I think it's natural and healthy to have a revulsion towards unnecessary excess.

It's not that they're $550, it's that they don't need to be $550. Choosing higher quality groceries, ordering delivery instead of going out during a pandemic, or even just buying things that will bring you and your children joy is on a different level than "I will get these $500 headphones instead of the $300 ones that do the same thing just because I can afford them".

Even if you're not explicitly trying to be as moral as possible with every purchase, there is a tangible difference between buying things that will improve your life or the lives of those around you, and buying things that are expensive just because you can.

Completely agree, that would make the experience more user-friendly for the person looking to rent.

This is an AirBnb platform issue, not necessarily a owner "scam".

Not a trivial engineering problem as the dynamic price based on length of your stay can't be cached easily as base-price-per-night, and I assume caching prices per listing is what makes the map quick to load and responsive, but it'd be a welcome change!

Me and my team use both, Slack and Teams, but only because Slack‘s video call feature is really poor compared to its competitor(s). I never really quite got why Slack dev was not able to at least close the gap to Teams in this area. The video call feature is still buggy and lacks important features, such as inviting externals (by calendar invite) or sharing screen AND video, not to mention a whiteboard. If Slack had been a bit more ambitious in this respect, Teams would never have been an option.

Those safety systems don’t exist in a shipping container sized nuclear reactor. One method that I think you’re talking about is when the temperature of the molten salts goes beyond a certain safety threshold then a heat sensitive plug is disintegrated and the Milton salts are drained into a safe underground reservoir for them to cool. (This is my recollection from that why thorium is the future video that went viral years ago) Can’t do that in a shipping container.
Are they noise canceling? If they're not, then it's not an apt comparison. These compete with Bose QC35 and Sony WH1000XM4.
