Elon knows that Apple is one company that he is completely powerless against. Apple has the visionary founder, all the money in the world, all the power (iPhone) and hundreds of millions of loyal fans. Apple has all the people with disposable income.

For a highly technical and intelligent group that is HN, being blanket negative on crypto is the battle cry, but pointing out how fiat is largely based on fiction as well ("faith" written next to a stone mason eye in a pyramid) is not tolerated.
That seems like a bad assumption. Even if there are 65 bugs, without taking a look at a sample of them you have no idea of the severity or relevance of those bugs.

Looks at a simplistic number without digging into the details will always be a poor way to evaluate the health of a project.
> I don't know what the perfect block size is, but quadrupling down on on block size and turning down all alternatives is not a good long term plan.

BTC's 1 MB (or a bit more with segwit accounting) is just hopelessly obsolote, we could easily handle multiples without any issue whatsoever, and it would require a massive increase there after to reach the state of "one or two nodes".

Further, BCH isn't "turning down alternatives". It's a permissionless system after all, and it does have malleability fixes if you want to have layer two for it.

It's BTC who is blocking any on-chain scaling and bet everything on the experimental Lightning Network (that's still experimental mind you).
If it was evolutionarily optimized, it most likely is not the most efficient way of doing something but it most certainly is the most resilient way.

> There are definitely situations where many interacting rules and assumptions produce deeply weird, emergent behavior

The problem is how due to other optimisations (mainly inlining) the emergent misbehaviour can occur in a seemingly unrelated part of the program. This can the inference chain very difficult, as you have to trace paths through the entire execution of the program.

The issue occurs for other types of data corruption, it’s why NPE are so disliked, but UB’s blast radius is both larger and less reliable.
At what price, though?

Model 3 Performance does 0-60 in ~3.4 seconds (3.1 seconds with 1-foot rollout, if you allow for that "cheat") for $63K.

I don't know of any other EVs that can beat that performance at that price point. As far as ICE goes, a Corvette can be bought for $64K that will do 0-60 in 2.9 seconds, but then you get a car that gets only 24 mpg highway and yells to every cop within a mile when you're gunning it. Also, I'm not sure how I feel about having that much power being applied to only the rear tires.
It’s amazing how fast everything in the core system runs when it runs trusted.

Rules-enforcing is, in my experience, pretty awful. One person mis-clicks and it creates a bad experience. Being able to grab someone's pieces and show them how something works is very valuable.

I really don't understand people who want rules-enforcing in their board game engine. Rules-assist sure, tell me where I can put those pieces according to the rules, deal out cards automatically, all that stuff.

Why do you want rules enforcement?
For years I would wake up every night around 2:30am and struggle to fall asleep again. When I finally spent a night at a sleep clinic, they told me it is a common symptom of sleep apnea. Once I started treatment with a CPAP machine, not only I was able to sleep through the night consistently, but also my chronic anxiety went away. The treatment is a bit of a hassle, but so very worth it.

It seems more accurate to say that the business model is contingent on a number of breakthroughs that may never occur. It's not hard to see how the development of a more (and, let's say, sufficiently) economical process would retroactively justify all the capital invested and press generated up to that point, especially if it can put an end to the ecological disaster and permanent superholocaust that is the modern meat industry.

Musk is obviously egging people on, but we are witnessing one of the biggest establishment attacks on someone that's doing something "they" don't like - probably the biggest since all the propaganda / hit pieces coming out when he announced he would buy.

This is an area where I appreciate Angular and Angular Material. Angular Material provides the "easy to make table", which itself is simply a styled version of the underlying Angular CDK library. CDK provides unstyled building blocks for the Material components, which makes it significantly easier to roll your own.

I still think the biggest user interface (UI) change from Microsoft was the change from Windows 3.1 to Windows 95. There were so many features and improvements e.g. the re-designed Open/Save dialog (not much changed since then). Later versions of Windows have never made the same leap between new versions of Windows. Sure, there are refined or tweaked features (or regressed!), but each new version of Windows felt like an incremental update from the previous version.

I think the next leap in UI and visual design from Microsoft was...Windows Phone 8 (2012). It was a refreshing and different approach to mobile design. The visual language 'Metro' worked well on mobile touch screens. But Microsoft took the bad decision to transplant 'Metro' (flat design) to the desktop. The result is a clumsy, jumble of inconsistent screens. It simply doesn't work.

I was born in the late 80s and C was my first language, in a community college intro to programming class.
C++ uses name mangling to give names to non-virtual methods. They are no different than a C function that takes a pointer, except they may use a different calling convention.

Even if the method is virtual, C++ compilers make an effort to call methods directly without indirection through a vtable wherever possible.

Doesn’t lab grown meat need a lot of growth serum, which is currently extracted from pregnant animals? So as it stands it is not a solution to help reduce climate change (nor animal suffering).

> This means, even if you really cared about the user experience of your customers you would only be able to make incremental improvements to the status quo or else be be rejected for being too different.

Isn't this a good thing, though? Creating software that most current users out there can be easily onboarded with and be productive and familiar with quickly, without too much work put into it.

I recently did an article on using Linux as my daily driver for a week and admittedly picking a really boring desktop environment (XFCE) was a pleasant experience: https://blog.kronis.dev/articles/a-week-of-linux-instead-of-...

Sure, things were occasionally broken for technical reasons, but at least the UX itself wasn't what was causing problems or friction. It's very much like using something like LibreOffice (with the default dropdown interface, or the optional ribbon one) after other office packages - it feels close enough to what you're used to not to be completely jarring, even if there might be other issues with it.

> Not that certain standards are not also valuable but it still a sobering thought that we are in a local optimum that we will never be able to escape from. (And I fear most products are not even hitting the local optimum but are getting worse when it comes to UI design but that is besides the point.)

In my eyes, not challenging the status quo and making incremental improvements is a good idea for the majority of developers out there (even in web development, where you have your navbars and your sidebars and so on), let the trendsetters take the big risks and take what is proven to work in the long run from them, without being impacted negatively by their failures.

I do, however, support the idea of usability studies and looking for what might be better than what we currently have, but redesigns for the sake of being "modern" or "trendy" just seems like designers going for the fun low hanging fruit, like large companies just changing around all of their product icons, instead of working on, say, accessibility, text contrast and so on.

> You also don’t actually have a spiral leakage pattern with NPT if tightened appropriately- the fitting it self deforms to seal it.

This contradicts every source I've read about NPT threads, e.g.

"NPT pipe thread design allows slight clearance between the thread crests and mating roots. This clearance creates a spiral leak path along the male thread crests. The spiral leak path is why NPT connections require a thread sealant to be leakproof."

https://www.industrialspec.com/about-us/blog/detail/npt-nptf...

"NPT, or National Pipe Thread (Taper) is an American standard for pipe connection dating back to the middle of the 1800s [...] they require a thread sealant, such as PTFE tape, to fill the spiral leak path inherent to the fitting;"

Thoughts?
I agree there are a lot of problems with the intersection of food and capitalism, and there's plenty of room for solutions to those problems to just... create new or different problems. That said, I don't think the key issue is "poor practice and animal welfare", it's exchanging another animal's life for a few minutes of personal pleasure and eight-ish hours of energy.

With sufficient research, I believe we can free ourselves and other living things from that dynamic without sacrificing the experience and benefits animal products provide, and I'd be happy to live in that future. We obviously aren't there yet, so I support efforts that bring us closer to it, even knowing they'll be sub-par for years.

And in the meantime, I agree: eating less meat and favoring producers who treat their animals well is the way to go if avoiding animal products entirely isn't on the table.
So... instead of mandating implementations to warn about (re)defining a reserved identifier, they introduce another class of "not yet reserved indentifiers" and advise implementations to warn about defining such identifiers in the user code — even though it's completely legal, — until the moment the implementation itself actually uses/defines such an identifier at which point warning about such redefinition in the user code — now illegal and UB — is no longer necessary or advised.

Am I completely misreading this or is this actually insane? Besides, there is already a huge swath of reserved identifiers in C, why do they feel the need to make an even larger chunk of names unavailable to the programmers?

It's a different enough system, I think it's worth restating what Linux's present ACLs are, which were based on a POSIX draft: They are additive permissions that model the Unix mode bits. Per-user and per-group, you can add read, write, and execute permissions that they otherwise would not have.

NFSv4 ACLs are far more powerful, modeled after NTFS ACLs (a proper superset, with an added two permission types). In network environments (where you'd use them anyway), they can assign access control entries (ACE) with Security IDs (SIDs), generally more stable and consistent across a network than ad-hoc Unix user IDs/group IDs. Managing with UIDs/GIDs is still possible, too. They add both allow and deny permissions to ACLs; if you want to deny "fred" from reading a file, you can make a deny entry for "fred" specifically.

The fine-grained permissions you can get from NFSv4 ACLs: READ_DATA, LIST_DIRECTORY, WRITE_DATA, ADD_FILE, APPEND_DATA, ADD_SUBDIRECTORY, READ_NAMED_ATTRS, WRITE_NAMED_ATTRS, EXECUTE, DELETE_CHILD, READ_ATTRIBUTES, WRITE_ATTRIBUTES, DELETE, READ_ACL, WRITE_ACL, WRITE_OWNER, SYNCHRONIZE.

READ_DATA, WRITE_DATA, EXECUTE are equivalent to the read/write/execute Unix mode bits. The two expanded features I find I use most frequently are blocking the deletion of files and making them append-only.
This post is very good. One thing to add, is that if you code has not entered a state of UB yet, but will at some point, then all bets are off. The phenomenon is generally known as time traveling UB.

Compilers assume your code doesnt contain UB. Example:

If(x == 0)
printf(“hello”);
y /= x;

The compiler can assume x is not zero because it assumes the user will not cause UB, therfore the if statement and printf can be removed.
On the other hand, attractive women sometimes get harassed. If you are an attractive man, many people will just generally
automatically be nice but also respectful toward you. Then you could end up with a cheery disposition because from your point of view the world is just a friendly, respectful place, and people are even nicer to you (or you could turn into a spoiled jerk, there are lots of paths).

As other people have stated in this thread, IBM Redbooks are what you need and they span the whole range from high level overflow to low level.

> And if there are, then why is there so little info for them on the web? Is the knowledge proprietary and secret?

IMO it is just a cultural thing. A lot of mainframe developers and especially the experts who have deep knowledge have been programming for a long time. Like, started on punch cards while they were getting a math degree.

The IBM culture has always been comprehensive documentation available from the source and predates the internet by a few decades, so the kind of public stack overflow culture we are used to never developed over there.

The book Hackers: Heroes of the Computer Revolution by Steven Levy kind of talks about this, the difference between the mainframe guys and the mini computer guys. Its a good read.

Mainframe people are descendants of the "high priests" that worked on computers before the invention of the mini computer and the culture reflects that to this day.

Having read a bit about the topic, the chemical profile of slaughtered animals includes some changes due to the stress and fear that the animal's experience just prior to being killed, like increased cortisol levels.

Meat from stressed animals will be "tough, tasteless, and high in pH, and will go bad quicker than unstressed meat." (From: https://www.atlasobscura.com/articles/why-scared-animals-tas...)

If you've read about factory farms that most meat comes from, it's a stressful environment.

On the other hand, lab-grown meat sounds would be zero-stress.

> I agree, none of these companies are crypto companies, just centralised scams. In fact, this is not the end of crypto, but is exactly the opposite. This is the "real beginning" of crypto, as now the benefit of decentralisation and transparency are being understood by a larger number of people. So all in all, this is great news for the crypto industry!

While I share your enthusiasm, even after countless rugpulls/exitscams/fraud proving centraization is the bane of why this tech was created; I don't share your conclusion as it doesn't reflect reality at all. The 'crypto' market is rife with this and has been sine the Ico mania (and alt boom before that really) so things like NFTs and DeFi are at it's core rely possible of this ignorance which is what most profit from and do so to the detriment to actual viable projects: Bitoin, Monero.

In short, all I'm seeing is a price correction, but real projects keep building muh needed infrastructure and 95% of the 'crypto Industry' are the hype tokens exchanges like FTX, Binance fleece the masses with with promises of short lived DeFi yield farming like scams.

Agreed, we have been persona non grata in SV for some time; in 2014 I went to the bitcoin job fair in Sunnyvale when I was launching my startup and despite having Standford heavy weights and Vc (like Balaji, Chamath, Dorsey and later Musk) soon realized just how poorly we were received outside of our circles; we represented the uncouth gate-crashers who were supposed to be kept at arm's distance, and only when fortunes were made only then would they even listen to us and even then they hose their own ilk who turn out to be the biggest scammers of all and then blamed us for their failures.

There is still time for a correction, but there is a reason as a Californian with a CSU STEM degree and wit family/roots in SV area I went to Boulder instead and never regretted it.

With that said SBF went to MIT, and his parents are Stanford professors, it was his GF who headed Alameda that is a Stanford grad.
There isn't a lot on Stack Overflow and the rest of the web because it isn't needed.

Mainframe programming is not like web programming. There are not multiple frameworks and languages competing for developer attention and rising and falling in popularity every few years. It is much more "there is one way to do it, it's the same way we've done it for 15 years" and that is what you do. There are very few new questions. All the common questions are covered in training and the more uncommon ones are covered in the documentation. If there isn't already a standard way to do what you want to do, you are probably doing it wrong.
The cost constraint for the decentralized network would probably be in design rather than engineering. If money wasn’t a problem I think the smartest way to go on about it would be to spend a lot on product design, prototyping and finding PMF while adhering to the mission.
