They do! I visited "El Mirador" in the forest of Guatemala.
And at one of the smaller cities on our way there, our guide pointed out that one of the small squares in, what was our entrance to, the town was probably used for playing a game similar to basketball but with a hard rock. There were also elevated places around it where people (albeit smaller in size) could have comfortably sit down and watched.

Edit: autocorrect is messing me up
There are two tracks leading from Manhattan to the west and south of the country. These tracks are shared between both commuter trains from the New Jersey suburbs (population 4.5 million) and Amtrak. Elsewhere, there are still two tracks in places.

The particular problem segment being discussed here does have four tracks, but it has commuter, regional, and intercity services. This is causing congestion problems; IIRC UK HS2 is being built because of a similar problem where they need to get the intercity trains out of the way of fast regional services.
Two men caught stealing bikes. What should S.F. do about them?
Are these shared rails with freight priority? I think that is a key issue with Amtrak service in most of the country. It is a halfway investment that deters further investment due to its poor quality of service but with dedicated infrastructure it would be very different in performance.
Right, we are in agreement. I think there should be rail in urban areas, but I was specifically refuting the idea that there was no room for rail.

If Apple actually cared about security & privacy they would make iCloud et al. E2E encrypted but they don't.

A sophisticated hardware attack is probably going to be government sponsored anyway in which case that government can just request data from Apple directly.
> As I understand it, Windows 11's CPU limits are designed for CPU's that have specific hardware mtigiation for Spectre and Meltdown

"To run Windows 11, CPUs need to have the hardware virtualisation features to enable virtual secure mode for Virtualisation-Based Security and the Hypervisor-Protected Code Integrity that underlies a range of protections that Microsoft has been building since Windows 8, like Application Guard, Control Flow Guard, Credential Guard, Device Guard and System Guard. Now they'll be on by default for all PCs, not just specially selected devices."

Accusing a business of being motivated only by money is completely trivial and in informative.

For example iFixit clearly cares absolutely nothing for user security and is only motivated by money. They simply don’t care if devices are secure as long as they can sell repair kits.

Also it is clearly in ifixit’s interest to have unreliable devices that break often and need more repairs. This is true of the entire repair business - all they care about is money.
The Dangerous Crossover Between Climate and Covid Denial (2020)

I remember one noble solved this in a clever way. He made it illegal for peasants to grow potatoes, and grew them in the his royal garden. Then peasants would smuggle them out in the night and grow them back home, thinking if it was forbidden it must be good.
Intel has been a spoiler in the GFX market for the longest time.

Every laptop I've had that has discrete GFX has had recurring bugs with both Firefox and Chrome because of the two-GPU situation. I would have the hardest time documenting what was going on, they'd fix the bug, then in the next major release it would break again.

> I bet that if the COVID vaccines were not called a vaccine, people would evaluate the risk reward trade off differently

Interestingly, one of the entry-level Covid denialist talking points is that the vaccine is "classified as experimental gene therapy, and not a vaccine".

It's probably not worth spending too much energy seeking logic in illogic. I just thought it was interesting and kind of ironic in this context.
Pretty sure unreal engine 4 and 5 have garbage collection built into the runtime
What we call a computer today is a stored program, general purpose, electronic digital computer. This was a known goal before WWII, at least within IBM. But each of those hardware features had to be developed. So, along the way, there were things like this reservation system which checked only some of the boxes on that list.

That was the heyday of special-purpose systems. Reservisor, Plan 55-A (Western Union's Sendmail made with paper tape and relays), Teleregister (stock market quotations), American Totalizator (racetrack systems), special systems for railroads, mechanically programmable Teletype "stunt boxes", plugboard-wired fire dispatching systems...

IBM had electronic arithmetic in test before WWII. But memory was hard. You needed something to store each bit, and that meant building a huge number of somethings. General purpose stored program computing had to wait until someone developed something cheap enough, large enough, and fast enough to store the program. Early electronic memory devices were the Williams tube (too expensive, not big enough), delay lines (too slow), and magnetic drums (too slow). Magnetic core finally got computing moving, but core was a million dollars a megabyte as late as 1970.

Here's an introduction to the UNIVAC File Computer.[1] The program was on a magnetic drum, so you only got maybe one or two instructions per rev. To speed things up, they had a plugboard, so you could wire up small subroutines to be triggered from a single instruction from the drum. Again, you see the struggle against memory cost and slow memory speed.

UNIVAC later hired Gen. Leslie Groves from the Manhattan Project. He thought big. The result was the UNIVAC 1103, the largest vacuum tube computer ever built as a commercial product. That monster came out in 1953. Stored programs in random access memory at last. The 1103 had everything you needed in a computer except affordability. Williams tube random access memory (1024 words of 36 bits each), large numbers of tape drives, peripherals, etc. They didn't sell many, but the successors (1103A, core memory, 1105, some transistors, 1107, all transistors) became more useful.

So, as I've mentioned before, it's not the lack of a theoretical concept of stored program computing that held back early computing. It was developing something in which to store the program and data.

AFAIK the only exception is Poland.

> It's generally not permitted in pharmaceutical products, some countries restrict its commercial sale

It's never been acceptable as food. Only as a mislabelled pharmaceutical product. That ended in 2002 after some nonsense in Germany.
There are four tracks, but they are shared by local commuter services, rapid commuter services, intercity regional services, and the actual high speed trains.

To put this in context, by the time suburban development started in earnest in the US, the private railroads were in free-fall after the war. It took until the '70s for Amtrak to put the (passenger) divisions of said railroads out of their misery, and Nixon did not anticipate Amtrak surviving the decade; Amtrak was supposed to decline out of existence. It never quite did that, but it also never quite got back on its feet, and so now the passenger rails are quite lacking.
Blueprint is already basically Haskell, I've done both and the similarities are striking. I think the world is ready for a proper visual programming language that plays nice with git, compiles down to native code and has all the nice abstractions that Haskell offers and none of the downsides of a scripting language. No doubt SPJ is one of the people who can help make that dream a reality, not in small part because just his presence will attract the best and brightest to Epic.
I prefer Python to Octave and Maxima. Numpy, scipy, and matplotlib for numerical stuff, and sympy for symbolic stuff. Having them together in the same general purpose language is really convenient, and Jupyter notebooks are fantastic. Sage is also good, but I've moved on to sympy. I don't know a way to get step-by-step working from a library, but sympy gamma can do some, so it's probably possible to some extent.

My experience suggests avoiding Maple like the plague. Sympy (and Sage) can do everything I ever used it for much nicer and easier.
You can care about security and privacy and also still care of ease of use. For 99.99% of their customers, encryption is enforced by default and being able to recover their data is more important than E2E encryption.
There's also https://keys.pub/ (from someone ex-Keybase, if I remember correctly). I haven't looked at either closely. Can anyone compare and contrast?
Show HN: Secure open source apps, avoid SSO-Tax and expensive enterprise license
1. Opensource tools (e.g., Kibana/Elastic, Grafana, Jenkins, GitLab, Hadoop, Spark, Kafka, Kubernetes, AWS EMR) typically don't have good authentication and authorization.

2. The enterprise license fee to enable SSO (SAML, OIDC/OAuth) for some of them is very expensive.

3. If you need SSO for more than one application, the total price tag can be prohibitively high.

You should certainly consider the buses’ share of the road cost, just like you should consider only the portion of the rail cost that is built and maintained for the commuter usage. If either of those shares is 100%, logically it should be burdened with 100% of the cost. Bus depots, bus maintenance yard, dedicated bus lanes, and bus stop turnouts should all be 100%.
Users who choose to repair the products they own with the parts they want at the price they're willing to pay are not being "manipulated" into anything.
Depends. In perfectly logical debate, you'd be right. But I think real world is more complex.

What if "who someone is" a "someone who is easily manipulated and used by bad actors to amplify dangerous misinformation"?

Or, someone being American person of color is pretty important when they talk about racism in US. As opposed to someone, who is not only not a person of color but has been to US like once for a week (like me).

Or perhaps more relevantly, what if "who someone is" is "a certified medical doctor" as opposed to "someone with no experience in medical field who gets their information from corporate social network who makes most money when people are angry because anger is very good for engagement"?

I was an original iphone user, and have been hearing about how unrepairable and how battery can't be swapped since then. I'll believe the iphone is unrepairable when I see it.

For those of your who suspect that these types of claims are a lie, they basically are. If you have elderly relatives, they often DO NOT want to upgrade their phone once they've got it working. A great gift is actually to take it into an apple store and pay for the "impossible" battery replacement for them.

It's $49-$69. You get a fresh new battery, all labor as well. OEM parts. My wife also doesn't care about the new phone, this is a nice and pretty cheap way to keep her old one ticking over.

Happy to do a comparison in 6 years on a Huawei vs Apple phone in terms of resale.

One thing to be careful of. I've been burned by used apple phones with second hand batteries in them. Apple now gives you a warning - worth checking for that if you buy used.
I think mandate is too heavy a frame in news reports and here.

The regulation requires a vaccine OR a set weekly testing structure. Seems reasonable to me though perhaps a bit broadly targeted.

Usually I think OSHA has specific regulations by specific industries.

PGP/GPG has much broader adoption, and is not fundamentally broken as a standard. It's also what people are used to. I don't know what to do with a minisign key.
And for the opposite perspective:

I love buying their flagship hardware because next year's flagship hardware won't be expensive after I trade mine in for 70-80% of the next device's cost.

This 3rd party repair fiasco just corrals people to AppleCare+ which I also enjoy.

In one experience, I did not consider upgrading my iphone as the yearly increments are not impressive, but my current iphone needed some repair. At the Apple Store in person, myself and the specialist noticed that due to needing repair it would not be eligible for trade-up, but was eligible for complete replacement capable of doing in person on the spot with full data transfer on the spot, and the complete replacement was eligible for trade-up on the spot, so I wound up with the new iphone. (note, I don't remember what I had to pay if anything, and it is possible that I upgraded to a phone with lowered storage space or something which made my trade-in of a more premium model cover the whole cost, that year)

to sum up: because I paid full price and for first party support, I got a free replacement device and a free next gen device. Maybe there was a downpayment somewhere in there I don't really know. In that circumstance I came out ahead.

Mathematically, I don't consider myself coming out ahead compared to the FIRE penny pinchers and frugal people, as obviously even if I pay $200-$300 a year then its more than what the people buying 3-4 year old phones are paying once every 5 years. But I'm not in a contest against the luddite compromises they make. I am glad that I have the convenience of never needing to consider the device "too expensive and fragile" and that complete upgrades never have a sticker shock because what I would have to pay is typically 80% lower in cost.
Most of the corporate IT leases employee hardware already and has 3-5 year laptop refresh cycles accounted for. I don't see how Windows 11 will affect anything in the big scheme of things for large enterprise IT procurement.

But as far as home users are concerned, I fully agree with you.
All your arguments hold if this was something the developper was trying to grow (commercially or not). Given this is clearly just an app made for their own use and scratch an itch... Taking about pleasing potential users/customers and how you'd have to be forced to install this app is more or less off-topic.
Ask HN: Searching for a SaaS/Startup Security HN Post
Hi everyone,

I found a really good, comprehensive blog post about a startup/saas security basics a few days ago. I wonder if anyone has a link to it. If so can you please share it with me here?

The blog post contains basic, bare minimums security stuff for your business including. Two things I remember from that blog post was that 1.) You should have at least email 2FA 2.) Logging for admin stuff.
If anything, western interests should be pleased to some extent that the Nationalists never held all of China after the Second World War. Chiang's regime may have been deeply corrupt and authoritarian, not to mention inept in so many ways, but if it had won the Chinese Civil War after 1945 and ousted the communists by 1949 (instead of the other way around), The Unified Chinese state would have adapted market policies (within the framework of an authoritarian government) much more readily and quickly than the Maoists did.

Instead of a China that finally got its shit together enough to be a global powerhouse only after decades of catastrophic extreme communist misrule by Mao and his immediate successors, we could have seen a China that pulled off an economic and political success story of power decades earlier.

How that would have reflected in the world of today is an interesting speculation on global power politics, especially between the U.S and a China that had developed markets since the 60's instead of in the 1990's being applied to its immense and highly productive population.

Most recipes have only standardized in the last 100 years or so. We didn't have exact temperature controls on ovens or stoves until the 1930s, which is a fairly easy way to tell, and even cooking units vary across time, place, and even household. (How big is a teacup? Depends on your glassware.)
Give me a break. A screen swap in a modern smartphone is not something you can do in a bar in the time it takes somebody to go the bathroom. You need tools like a heat gun to even get the things open which greatly greatly limits the scenarios where and when something like this could occur.

Why a Pi though? You're obviously not making use of any of that expensive IO other than the eth...why not just offer a "Pi-compatible " custom board* that's actually designed in a sensible way for this use-case? Would be substantially cheaper and more energy efficient.

*Or really just shared hosting w/ containers running Raspbian on standard server hardware with a nice onboarding workflow for migrating from a real Pi would likely be sufficient for most people's use-cases—if you're not using peripherals I imagine you don't have any need for the real time OS features?
DirectX 12 support is getting better with Proton and VKD3D. It's not universal yet, but it works better than I ever expected such efforts to go. Today, I was able to play a game again than I have pretty much given up on playing on Linux. Granted, it probably does not use DirectX 12...
Only reinforcement learning is based on Skinner's ideas - neural networks are instead based on purely mathematical and statistical methods - bakcpropagation and gradient descent. Other methods such as Support Vector Machines and Genetic Algorithms are also completely unrelated.

RL is useful for certain constrained problems, such as game playing, but it does not generalize well.

Additionally, all current ML methods are extremely slow to converge (they require enormous training sets compared to most biological learning), and they generalize pretty poorly outside their initial domain. So, their success is not a good argument in favor of Skinner's models being a good model for biological learning.
What a straw man! Coffee pods, automated litterboxes, dish washers, and all the rest don't carry an individual's entire digital life on them. You're literally comparing devices that really don't need any kind of security (other than, at worst, network security) to devices that demand privacy and security.

This is either a disingenuous attempt to downplay the important of hardware security or an extremely ignorant analysis of the situation being described.

This is a dumb question but how far "back" (regressed) would we have to go to get "open secure" hardware?

ie we decide that having open sourced hardware designs and some way to verify the silicon matches tha hardware is the way to go.

This is not just the CPU but all the chips on a motherboard, GPU included?

IIRC Russia still fabs 286s for its military because they have verified the design and don't have to worry the NSA has added a few extra circuits.

I would guess we would could go a couple of generations back before the reduction in power more than was compensated for by the presumed extra peace of mind?

My greatest achievement on Wikipedia was fixing the page on Herostratus, to cite him as being accused of torching the Temple of Artemis, rather than baldly stating he actually did it.

The article itself says he confessed under torture to having torched it so his name would remembered forever. But that doesn't even make sense on its own terms: If he wanted to be remembered for having torched it, why did they need torture to find out? In any case, confession under torture comes nowhere close to establishing a fact, not that that has often stopped somebody who wanted a body to string up, and didn't much care whose.

I would have many other great achievements, but they get reverted by self-important gatekeepers.
