> One article isn't a showstopper, but I really wish this didn't surprise people so much.

It is surprising because given the rest of the "Red" states' records, Utah is an outlier:

> Eighteen of the 19 poorest states have legislatures where both chambers are Republican controlled. New Mexico (46th richest, fifth poorest) is Democratic. But there isn’t another blue or purple state until you get to purple Maine (31st richest, 20th poorest) with its “split” legislature of one party in each chamber. All the states in between (such as Tennessee and Florida) are Republican, both chambers. So is Michigan, where Republicans hold all high state offices (where Donald Trump won in 2016). Above New Mexico, you jump all the way to middle of the pack Vermont (27th richest, 24th poorest) to find a state with both legislative chambers held by Democrats.

> But all five richest states have both legislative chambers controlled by Democrats – Maryland, New Jersey, Hawaii, Massachusetts and Connecticut. Overall, Democrats dominate the 20 richest states.

> The people have had the resources they would use to deal with it diverted. Low tax scenarios are much more fault tolerant. High taxes won't necessarily promote equality or great outcomes.

When there are haves and have-nots, often expressed in (e.g.) a high Gini coefficient, things generally do not improve for the have-nots over time. As the 20th century has shown, especially in the post-Gilded Age post-WW2 era, taxing to fund social programs tends to improve a society in many ways.

Crazy time. I was fantasizing about a complete crazy thing lately. What if there was some small device that could turn energy into carbon capturing? Let says there was such a device, we could mount it onto every bicycle on this planet and every time people drive around it might be a bit more exhausting (good for your health!), but at the same time we would capture carbon from the air. Is this a crazy idea? I guess it is... But somehow I think it must be possible! If you know how to built it, let me know. I will sell it like crazy ;)

How can you use cgroups2 for this? I know that BSD resource limits are basically useless for this as they only allow to limit virtual memory, not RSS use.

EarlyOOM [1] is a configurable daemon that kills processes early enough to (hopefully) prevent thrashing. I'm using it on my Linux desktops (it has proven to catch my own programs' runaway memory usage before it risks locking up the development machine), but it may also be useful on servers. It logs to syslog but also can be configured to run a program on kill events.

[1] https://github.com/rfjakob/earlyoom, https://launchpad.net/ubuntu/+source/earlyoom, https://packages.debian.org/search?keywords=earlyoom

(Why would a user space OOM killer be necessary if the kernel has better information about the state of the world? I don't know the details, but my interpretation is that because people disliked OOM killing, the kernel devs made the kernel OOM killer trigger so late that it is largely useless. If that's true and thus a social problem, maybe it needs to be solved on that level, too.)

BTW in my experience, Linux 2.2 used to handle out of memory situations much more gracefully than any later kernel version.

Back in 1996 I developed a TCP/IP stack from the ground up based on the the DARPA and RFC specifications from that era. The impression I has from the quality of consistency was that TCP/IP was a students project. Delayed-ACKs was described briefly as a concept in addendum. Implementing it was a nightmare.

What happened was that with bulk unidirectional flow (FTP) the window would slowly fill up until it was completely full after which transport would halt to a grinding stand still. Only when retransmit timers triggered would transport resume at full speed, slowly filling the window to repeat the cycle. As I can remember, this cycle would repeat every 5 seconds or so.

Out of sheer frustration I logged all traffic with (then) high resolution timestamps and hand drew both sides of the connection on 132 columns zigzag printer paper which filled the corridor.

As it turned out, the protocol state timings assume that the transit time is 0ms. For one-on-one REQ/ACK this isn't a problem, for delayed ACK it was a game-breaker.

When a packet arrives, several tests are performed to determine if it is within sequence and rejected otherwise. With delayed ACKS the administration did not represent the actual state triggering lots of false negatives.

Solution was to create dual state information. One being the actual values for the end-point, the other being the projected/assumed state of the other end, taking into account it is suppressing ACKs. Then, for incoming packets, the headers are tested against the projected other-end state and transmitted packets constructed using the this-end state.

Performance hit the roof and filled the cable with 98% of the theoretical bandwidth. Much more than stacks implemented by competitors.

Sadly my employers did not allow me to publish the findings.

> This is tearing the US apart by the seams

Democrats are doing a pretty good job on that on their own. They attempt to force thoughts and beliefs on others, “cancelling” anybody getting in the way. When was the last time you saw a republican NOT getting screamed at by some liberal on any of the popular sites? Even now your comment reads as though you don’t want the parties to work together.

> We are now in a situation where the president is openly attempting a coup on the popular vote

We don’t use popular vote though. We use electoral college. And the media is overplaying this to induce panic from people like you. He’s not going to stage a coup, and if he did, even the republicans would stand against him. Calm down.
They didn't even ask for more details. They obviously didn't attempt to reproduce anything. They just closed the issue. The person who filed later noted that identical electron versions in earlier VS Code editions do not have the same problem.

This doesn't appear to be a tiny issue either. It is leaking quite a bit of memory rather quickly. They need to find where they're retaining references in one version, but not the other (that kind of thing is what MS pays them for).

This is a good summary - and it might just work out. There is a trend in our energy sources being more powerful and more efficient over time. More efficient solar panels, biger and more flexible wind turbines, bigger and safer nuclear reactors. So paying the "energy dept" in the future might be much easier than going without the fosil energy sources right now.

> “ Regarding recommender systems I see many companies trying neural nets and so many other fancy ML stuff for things that - in AB-tests are always outperformed by basic rules.”

I work on large scale recommender systems for an ecommerce company and in my career I’ve seen only the exact opposite.

Don’t get me wrong, sometimes simpler ML models, like clustering LSA vectors or nearest neighbors, work better than complex models like neural nets.

But I have never seen plain rule systems work better for any problem even remotely at scale. Rule systems give an illusory sense of control and understanding, yet are rife with complex interaction effects and edge cases that typically make them intractable to change.

ChargePoint Rocketing Higher
ChargePoint ($SBE) continues to break investing with a crazy SPAC run up in the EV space to the likes of Tesla, NIO, and others.

Perhaps the biggest differences being:
- they offer a durable and well-liked product
- they operate over 100,000 charge stations globally
- they did $150M in revenue in 2019
- they own ~70 market share in the US as charging underpins EV adoptions
It's a good question, and much of it comes from this: most people don't agree on what the government should do with taxes, especially at the detailed implementation level. Also, as you tax people, well, freedom isn't very useful without the financial means to exercise said freedom.

Thanks for sharing that deck! The section on volatile memory retention time/temperature stood out to me:
for SRAM, at room temperature the data retention time varies from 0.1 to 10 sec
– cooling SRAM to -20oC increases the retention time to 1 sec to 17 min
– at -50oC the retention time is 10 sec to 10 hours
I imagine that there are very few places in the world where people universally love their public transit if they're dependent on it day-to-day. Whether it's cost, frequency, coverage, reliability, frequency, comfort, etc., something that seems perfectly adequate or even pretty great to a sometimes visitor seems less so if you're commuting at rush hour every day in all sorts of weather.

You mention Swiss train service for example which seemed pretty great as a visitor--but it sure wasn't cheap as is true of a lot of European train service. Ditto for the Shinkanzen in Japan.

My personal experience is Boston. As someone who takes rail into the city and then the subway maybe a few times a year, it seems just fine. When I depended on it for regular commuting, I did not love it.

This is amazing! I had a question about this passage however:

>" MyNOR is a single board computer that does not have a CPU. Instead, the CPU consists of discrete logic gates from the 74HC series ..."

Isn't that still a CPU just not a integrated chip or microprocessor? Isn't a board with discrete logic gates basically how mainframes and minicomputers such as PDP-11 etc were built before the advent of the "microprocessor"?
Why Is Scientific Illiteracy So Acceptable?
I have a Chevy Volt as well. But we also have an Outlander PHEV. I wouldn't call the Volt a PHEV or include it in the same category as the Outlander at all. The Volt is an electric car that happens to have an ICE as backup. the Outlander PHEV is a soft hybrid with a bigger battery. It's pretty much impossible to drive it without using the gas engine, even when you hit the "EV" button. And from my impression that's the case with pretty much every PHEV other than the Volt.

But we needed a people mover that fits kids, dogs, skis, etc. for longer trips. So that was the best compromise.

It's a shame they killed the Volt and screwed up in marketing it. Such an amazing piece of engineering. I don't like GM's products generally, but I would have bought an Equinox type vehicle with a Voltec drivetrain and paid good money for it.

I see the article more as a broader metaphor for the AI hype. Take, I dunno, video recommendation.

Sure, YouTube itself proably built insane stuff in their engine you could never replicate with classic methods (ignoring whether the YT algo is any good).

However, if we are just talking about the Vlog of your real estate company, you should probably A/B-test whether your viewers prefer order by time or clicks and implement a decent title search bar. And kick the consultant hyping you up about ML out, now.

So my takeaway is that is not about whether AI is never useful or about 2D steering, but about using the right tool for the right job.

And building on that, I have to give the author probs to demonstrating an alternative solution to I problem wich I would have definitely solved via AI.

That’s a very unfair distinction, almost like a No True Scotsmam fallacy to say machine learning is only bad and other stuff is only good (in terms of transparency).

But machine learning has predated neural networks by hundreds of years. The core mathematical basis of all machine learning coursework linear regression and decision trees. Other models like SVMs, Bayesian models, nearest neighbor indexes, TFIDF text search, naive Bayes classifier, etc., are basically like machine learning 101, and they have many different properties regarding interpretability depending on the problem to solve.
Absence of the period (aka full stop) after the timestamp appears to indicate that a commenter had previously (perhaps recently) posted a comment which was subsequently flagged. Or that the commenter is new (see below).

Here's what I did:

I used ctrl-f/cmd-f on a well-commented post (https://news.ycombinator.com/item?id=25190668) looking for the following search terms: ". [–]" and "o [–]"

Then I reviewed some of the posters' recent commenting history. Those that had no period after the time-stamp had recent grayed-out comments. I did not find any commenters with a period who had recent grayed out posts.

For instance, here's a page from esteemed commenter buran77's profile: https://news.ycombinator.com/threads?id=buran77 . You'll notice that not only does buran77 have grayed out posts without the period-after-timestamp feature but so does grayed-out commenter elmo2you.

The absence of the period also appears to apply to recently created accounts. See green commenter jn6118 in this thread.

>Capitalism is busted and rewards greed and concentration of wealth.

Capitalism always had a cyclical nature presumably because humans are cyclical. Things go wrong and then they go right and then they go wrong in an endless cycle. It's like an engine that breaks down every now and then. You can fix it and you should.

>It doesn't take a galaxy brain super genius to figure out that an economic system that relies on infinite growth doesn't exactly pan out in the long run

Capitalism doesn't rely on infinite growth. It drives growth by rewarding increased productivity and innovation. However, since it does so through monetary rewards it is entirely possible that government policies make it easier to acquire money through non innovative or unproductive means. QE and low interest rates are a pretty good example of this. That money can be used to acquire competitors or simply stay alive for much longer.

I disagree.

We don't find these systems intelligent because, on inspection, they arent.

We are intelligent. Not "magically", but actually nevertheless.

Our intelligence, and that of dogs (, mice, etc.) consists in the ability to operate on partial models of environments; dynamically responsive to them; and to skilfully respond to changes in them.

This sort of intelligence requires the environment to physically reconstitue the animal in order to non-cognitively develop skills.

It is skillful action we are interested in; and precisely what I missing in naive rule-based models of congition.

Most of these issues are non technical. Any technology that does anything with money will attract scammers, criminals, charlatans, etc. like a corpse attracts flies. That's not a fundamental problem with the underlying technology but actually a robustness test for it.

The banking system fails this test regularly BTW. It too attracts the same variety of people and recent history is littered with people testing the limits of the system and causing minor and major financial incidents as a side effect. Our legal system actively protects these shady types too. You could say that blockchains are designed to function despite the presence of such people. So, their presence is a given but not necessarily a bug.

Now specifically Ethereum 2 is proof of stake; not proof of work. So it has limited energy issues associated with v1 and Bitcoin. This also kills the mining use case and shifts power to those holding stake.

Transaction complexity and throughput remain problematic compared to non block chain based systems but are probably good enough for most use cases and of course vastly better than v1, which I would argue was never really suitable for any serious use cases because of its slow transactions and uncertain outcomes when they spanned minutes to hours instead of seconds (which also stops any kind of interactive payment scenario dead in its tracks). Using side chains for micro transactions, payment channels, etc. is a common/practical workaround and probably also desirable from a privacy point of view.

Pseudo decentralization is policy choice. Different blockchains make different trade-offs here. There's inherent friction between purists/utopioans on one hand and people to do real stuff on the other hand. Pure decentralization is mostly not very practical in a lot of domains and technically overkill for common requirements. In the case of a financial system, you in any case need the buy-in of legal entities and governments. There's an implied level of central control. That's why ripple and stellar are popular with fintechs. Good enough as a shared ledger and for implementing e.g. remittance networks and complex financial products. Enabling anarchists is not a design goal for them.

In the end, a blockchain is just a tamper proof block chain. You use it in a legal system that may or may not allow you to use it and that may or may not provide you some legal protections against ripped off. Facebook found that out the hard way when they tried to compete with central banks last year and then realized that that would put them in the cross hairs of financial authorities, which is when they backtracked their position doing something weaker at some point later (probably never at this point). Stepping outside the common legal frameworks is only easy if you are not really a part of it to begin with.
