"meet new people" is missing from the list. I wonder how diverse a 20-something's circle is these days vs 20 years ago. I used to talk to as many different people as I could: motor cycle mechanics, Johns Hopkins post docs, NSA engineers, actors, set dressers, woodworkers, painters, business owners. Does the opportunity to get out of your "social bubble" still exist today?
If they're self aware enough to know how good they have it, why do they struggle with the job because of how entitled most Google employees are?

Chastising or berating people for struggling regardless of their circumstances is an incredibly shitty thing to do.

You should be clearer what this actually does.

All mainstream CPUs and operating systems are dynamically adjusting frequency and other internal behavior to optimize power versus other factors. Some of these adjustment are done in hardware (i.e., intel_pstate aka "speed shift" aka HWP) which is both faster than software and can use internal metrics not available to software.

So you can't just say you're adjusting frequency dynamically to be optimal: something like that (or an attempt, at least) already happens. So what does this tool really do?
In my case, the actual plugin doesn't work without Javascript, and this was actually the cheapest option for hosting and staying within what I already had in my Nx monorepo. (it literally costs me $10 a year and I'm only paying for the domain)

I'm looking into some options for this with cloudflare, but it's been pretty low on my priorities for the above reasons. I'm also one of those people that turns off javascript by default, so I know your pain, but I'm also not a multi-billion dollar company.

Then how do you explain the extraordinary predictive power of QM, and why do you believe that the same maths that gives us measurements accurate to 23 decimals is completely inaccurate in its predicition of QC?

30 years is nothing given how complex the engineering problem is of actually building a working QC. Fusion is much simpler and very well understood and yet it has been more than 50 years since research into fusion power plants has started, and the most optimistic estimates say we'll have the first ever research power plant 30 years from now, if everything goes well (EUfusion's DEMO plant).

He saw it as a challenge. Here is a good podcast episode about it

> Unsure of how to hook such an architect for their modest home, the Jacobses put it to him as a challenge: could he build them a nice house for $5,000 (around $85,000 in today’s dollars)? According to Jacobs, Wright responded that he had waited for decades for someone to ask him just that question.

It's not an either or thing.

The nice thing of interconnected grids is that you can route around the bad bits. There's no such thing as a global shortage of power generation. Blackouts happen when there are local shortages. Which in turn usually means problematic local suppliers and a lack of connectivity to external suppliers. The key challenge on e.g. the European grid is moving renewable over production to where the demand is. E.g. Southern Germany firing up more coal/gas when the north has ample wind production is because they lack the transport capacity (i.e. cables). Grid interconnectivity increases the profitability of renewable.

Microgrids and batteries are indeed popular in much of the developing world where grids are very unreliable and power generation lags way behind demand. India, the middle east, much of Africa, and probably South America, etc. Grids are much less reliable there and investing in private capacity is essential and something that people do as much as they can so they can keep the fridge on, their phones charged, the AC on, etc.

In developed markets, people do the same but more for cost than resilience reasons. Though I can imagine Texans might be considering both after this year.

Syncthing. Been using this combination for a few months now and seems to work fine between an Android phone and a few Windows + Linux machines.

I had previously been hosting TiddlyWiki from my phone, but offline editing + opportunistic syncing when on WiFi seems to fit a personal wiki better for me.
You're spot on, it would provide limited information. In fact, it may be better to use a network monitor to trace network connections and graph that. Old network rules stick around, and so a graph of just the rules would show you connections that may not exist. And network rules are often made of CIDRs or port ranges, so it's not telling you what actual nodes are receiving traffic. If the CIDR and port range includes multiple networks with multiple components each, you don't really know what's connected to what. Distributed tracing is basically that from the application layer (and includes network calls).

Like yourapostasy says, this kind of post-hoc system design can lead to fallacies, and doesn't contribute to the initial design of the system. If you have nothing else to go on, it helps. But your time is probably better spent investing in formal specifications, and then developing components, connections, and all the operational aspects as implementations and validations of the specification.

Many papers have been published about this, spanning from the 70s to the late 90s, talking about the evolution of software systems engineering. After the 2000s, software engineering became more art than science when the Agile Manifesto gave everyone an excuse to stop caring about rigor.
That is more or less my conclusion, however it seems incredibly hard (that me personally) to find out if they have that skill during an interview. Do you have some tips on that?
The last nuclear power plant in Germany will get shutdown in less than 15 months. With that in mind, there have been no investments into them for years. You won't be able to keep them running by simple maintenance. That ship has sailed for years. What do you expect to happen?

> this technique isn’t new, although it sounds like it might be much more targeted here and implanted in the brain rather than the pain site @josephpmay

Uh... That's the 'new' bit. These are extremely thin electrodes that are implanted into the brain tissue.

That is an entirely new procedure and process.

All other pain management attempts to block the pain signaling down-stream. These down-stream signal blockers have very limited effect as the machinery in the brain still sends the signals.

This process prevents those signals from being generated.

THAT is entirely new.

Implanting electrodes directly into the pain management area of the brain...

THAT is entirely new.

Don't denigrate someone's work. That's childish.
Are we just ceding Javascript to Microsoft at this point due to the ubiquity of Typescript?
Looks like the article argues that because WireGuard tries to do one specific thing and do it well, without doing all the other things - it is doomed to fail. Unlike all those other technologies (IPSec, OpenVPN) that do a gazillion different things and are not even supported as a standard across the various operating systems and vendor devices.

Idk, seems like someone is trying very hard to defend their solution by vaguely throwing empty criticism about a new technology. Not even very convincingly.

From time to time someone can write a critique about X that actually touches on the bad parts, but this article is not it.

What has any of this got to do with "emerging as a field"? Mathematics is alive and well and, indeed, popular. It's not like Mathematics lectures are empty or that huge numbers are shying away from engineering or physics because of the Maths involved. Like, it's doing fine, and clearly "emerged as a field" centuries ago.

I don't give a fuck if people hate Maths, it's doing fine lol. You sound like someone who has literally no connection to the field and therefore can not perceive how it is actually doing, and instead you think "wow Maths must be in a bad state if everyone hates it". But no, that is just not true...

If there is any relevant criticism of Mathematics it is much more about going extremely deep into vastly theoretical domains without any reference to how practical such solutions might be than anything to do with whether or not the lay person "enjoys Maths".

All of this is irrelevant bullshitting. Maths emerged as a field centuries or even millenia ago. Please read the wiki page on "Mathematics".
Yeah, it's like there is something in their brain which differs from non-mathematicians.

Non-mathematicians discover something and then want the largest number of people to understand that thing as well, and they want to be the ones explaining it and see the sparkle in the eyes of the ones receiving the information and "getting it" for the first time.

Mathematicians want their peers to understand first and foremost in the quickest way possible, they then rely on 3rd parties to explain it to people who they consider "normies", they slap their name on the theorem or the demonstration and further use what they consider "subordinates" to explain it to the few "normies" who want to make an effort to understand it.

I’ve seen several brain-electrode stories on HN in the last couple of weeks. Has there been a breakthrough in the underlying technology or theory of this medical technology?
There is no solid math or physics which supports time travel. There are a lot of cases where people claim to have found some loophole or another in the impossibility proofs for time travel, sketching out a model that looks plausible at first glance, but they all end up postulating some blatantly non-physical entity somewhere along the way (i.e. cosmic strings, negative energy density, ... - I've gotten my hopes up quite a few times).

Speculating about parallel universes is a different story - even if they exist, we can't travel to them, so there is no sense in claiming that we can somehow harness their power. It's a philosophical question, not a physical one. In contrast, the rules of quantum mechanics (when phrased in terms of density matrices, at least) only describe things we can actually measure and observe, and people actually do test every single aspect of the predictions quantum mechanics makes.
Does anyone know the relative efficiency of, say, pumped hydro or lithium battery storage vs, say, a 1000km transmission line? I'm curious how local storage stacks up against something like sending solar power half way around the globe.

Sure, but anyone holding that much wealth could expect some kind of "advanced persistent threat" working against them to either destroy all of the backups, or transfer the coins to /dev/null after extracting any passcode from the owner. The keys and anyone that knew how to use them would need a high level of physical security. The "costly militarized facilities" would still be necessary, contrary to the author's statement.
Can anyone speak to the performance and power efficiency of ChaCha20 on current mobile devices? That seems to be the only convincing technical argument the author makes given AES-NI’s ubiquity.

QC is a direct consequence of the known laws of physics. To discover QC doesn't work would be proof the QM is fundamentally wrong - not that there is some more fundamental theory, but that we have been accidentally getting the most accurate predicitons of any theory in the history of science.

That possibility alone is worth all of the investment in this field.

In contrast, String Theory is just an extension of QM, motivated by nothing except some cool looking math. It doesn't even make any definite predictions (supersimmetry is possible in string theory, but not required, at least not at any particular energy level).
They are vaccines in the sense they stimulate the immune system to fight the virus, but are weaker than traditional vaccines. It is pretty clear by now that VE against infection rapidly fades over time (6-12 months), say goodbye to herd immunity. There are encouraging epi and B cell studies that indicate VE against severe infection holds, but it's still relatively early in the pandemic. We lack long term data plus virus mutations are a risk factor. Hope for the best, but be cautious of premature victory proclamations.

Well, Europe's nuclear power plants are on average more than 35 years old, they simply can't be operated for centuries, instead the are becoming unreliable. In 2019 France had 5580 reactor days with zero production. Regarding new builds in Europe, those still being built are behind schedules, OL3 in Finland with a 12 year delay. https://eu.boell.org/en/2021/04/26/nuclear-power-european-un...

You can build a lot of wind and solar parks in that time and updated old one-way dams with pumps to have them a large scale batteries. All that decentralized, thus creating jobs all over the country.

It's worth noting that an $85,000 house back then would be much more extravagent than an $85,000 house today as housing inflation has exceeded official inflation rates. Probably more like a 3-400,000 house if I had to guess. Still, an average house.

Tangential, but does Netflix have a reliable keyboard shortcut to pause the video? On Chrome, it seems to break when you switch the keyboard focus to some parts of the UI. You're also prevented from seeking backwards at the credits without clicking a button first (one is "watch next episode").

I can see why the second one might be a deliberate design choice to push you to watch the next episode but I'm surprised the first isn't caught in user testing unless there's another shortcut. Youtube lets you press `k` to pause which seems to be reliable.
Rats, people, just rats for now.
Others pointed out that it's hard to measure subjective factors well. I'd point to a different issue - if you have a metric for, say, wellbeing which is correlated with what you actually care about, putting pressure on other parts of the system - like maximizing engagement - will systemically warp those metrics to be less accurate.

For an extensive discussion of how this can happen, see: https://arxiv.org/abs/1803.04585

Out of curiosity, what proportion of monthly costs do interest payments typically make up for a mortgage holder in the US? In Switzerland they current make up 25-30% if you are in the affordability range that banks suggest, with the rest going to taxes, upkeep etc. And renting a comparable property is 50% or so more experience. So I feel like there is some slack until it starts heavily affecting the decision whether to buy or rent.
I somehow missed a comma and read that as "rat people, just rats now" and my mind raced to interpret that in sooo many different ways.
It’s crazy how much has changed in the data space in the past few years. You can basically set up a ‘modern data stack’ by swiping a credit card and buying fivetran (EL), snowflake (warehouse), DBT (transform), and hightouch (reverse-etl) for extremely cheap and without the need of an engineer. Just need to know SQL.

I think more companies are going adopt this modern data stack earlier in their data maturity lifecycle.
It’s highly unlikely that anything that has an effect will have zero side effects.

There is a Frank Lloyd Wright “skyscraper” [1] you can stay in in Oklahoma. It was designed as an office building, not a hotel, but it’s immediately obvious when you stay in it that it’s impractical for just about any purpose.

The rooms are triangle-shaped. Just let that sink in a minute.

My favorite story from the tour was about the penthouse, which was intended as an office for the CEO of the company that commissioned the tower. The office chair was part of the design, and its the most uncomfortable (and immovable) metal abomination you’ve ever seen. FLW was so obsessed with the form of the desk, that he wouldn’t even allow a telephone to be placed on it — the owner had to retrofit one to be installed after the project was complete.

His building look lovely, and he was very influential, but his residents paid the price for that influence.

I don’t really understand the economy. Here’s why: it’s entirely artificial. We, humans, make the rules. We control the input and if we don’t like the output we can just change that too. The market doesn’t actually exist. It’s just pieces of paper and bits on computers. A car can malfunction because it wasn’t built properly or because something breaks. A human can get sick because it gets damaged somehow. But the economy is a concept. So if we think houses are going to suddenly become worthless it’s because we think we’re going to, as a society, stop seeing value in houses…it’s not like something about houses makes them less valuable. They don’t have value in the first place except because we want them to. So…is it because banks have extracted all of the value out of other things? Banks want more money, so they suddenly say houses have no value and because of that they can beg for and receive money from the government? None of it is real…it can’t actually stop working.
