Thanks for the kind words - it's a real boost when someone talks about how my work has influenced them! I would be happy to have a chat - are you in the UK? If so, we are 5 hours behind you, so we can plan a chat time accordingly... We could start the ball rolling by you pinging me at jpaulmorr@gmail.com ...

I took a look at your first (?) video, and IMO the human factors are amazing! That said, however, our areas of application seem a little different: at least your video is mostly talking about numbers, and I assume a mostly synchronous world view, whereas my work uses data objects ("Information Packets") travelling between asynchronously executing components... Given your orientation, it makes sense to be able to flip back and forth between visual and text representations - not sure it makes as much as sense in my environment! However, Chuck, IIRC, in one of the projects I worked on, built a network of around 200 processes, without drawing a single picture!

Talk soon!
Uh, well the original developers of the Sun JVM didn’t do such a bad job after all when designing it: https://docs.oracle.com/javase/7/docs/technotes/guides/secur...
Yes, but for now only if you use custom data structures.

Custom allocator support for the std types (Vec, HashMap, etc) is coming, but at a snails pace.
Nope, not the same. Bitcoin mining does not "produce" hashes, it "produces" Bitcoin blocks. All that changed with the improvement in hashing speed is the number of hashes that must be computed before a block is added to the block chain.
I believe it's fairly well established that Joe Lubin holds somewhere around 10% of the Eth supply. Anyone with large holdings is incentivized to spread those holdings across many accounts to avoid scrutiny.

Pretty much every coin has substantial gini coefficient issues.
Things will be priced in bitcoin. You mean like how things are priced in gold now? Oh wait, we got off the gold standard specifically because of its high short-run volatility. Hmm....
Java does. Of course it’s never been used systematically and it has received precious little attention to DevOps ergonomics, but the infrastructure is there
Prof. Wirth, when designing the Oberon language, adopted this heuristic: a new feature could only be added to the compiler if it reduced the time it took to compile itself.

Now this doesn't quite apply to cPython, of course, and even PyPy is written in RPython, not Python 3, (correct me if I'm wrong on that, eh?) so it doesn't quite apply to that either.

Every time newfangled geld like this comes down the Py3 turnpike I think of all the other Python implementations that either have to implement it also or get left behind: PyPy, Cython, Jython, Brython, Skulpt, Stackless, Pyjs, IronPython, PythonNet, MicroPython, Nuitka, ShedSkin, Transcrypt, etc., not to mention tools like Snakefood or PySonar or MyPy.

(I'll shut up now, you don't want to hear it. I read the tutorial on the new matching and by the end I found myself chanting under my breath "Cthulhu fhtagn! Tekeli-li! Tekeli-li!")
I was talking about Browser-side, the cleaner node.js solution is to use the "exports{}" map in the package.json [1] that I mentioned before.

Personally, I wouldn't recommend to override the require.resolve or import.meta.resolve algorithm, as this is heavily experimental.

>There have been ways that a counterparty can close a channel in their favour if you aren't online. Perhaps this has been fixed by now.

AFAIK the fix is to have a service (or multiple) stay online for you, and I believe it could be done without requiring access to your private keys. If your counterparty broadcasts a stale transaction that's in their favor, your service will broadcast a newer transaction that reverts it.
The CPU architecture is Intel’s, but the platform architecture, like the BIOS, the hardware features, etc., are IBM’s.

There’s basically nothing left from those days, but it’s still a thing that people say sometimes.
Bitcoin is not counter-correlated. When the stock market corrected last year, bitcoin also crashed.
1) You're (outside of some relatively small models) very right here, but TV manufacturers are starting to push 8K sets with negligible benefits for most people's scenarios and little to no native resolution content.

2) Absolutely. One of my eternal frustrations is many people's hyperfocus on a single metric when comparing products (resolution for TVs, megapixels for cameras, clockspeed for processors, etc.). Your average consumer would be much better off focusing on other image quality improvements like the things Rrtings includes in their reviews.
I use Paw for GraphQL every day, including variables, schemas, and docs. The autocomplete works well enough, and when plugging into the larger Paw project things work very well.

My only big gripe is I can't write JSON to modify variables, I have to interact with a JSON tree UI and add items one at a time.
The coal ingredient still vents off toxic and radioactive waste in the making of the polysilicon.

And with the rapidly falling price of PV, it's unlikely we'll see expensive investments that do not reduce costs.

Nano could be wildly more accessible for beginners with an easy config like this that sets saner keyboard defaults. It also enables the little-known mouse support, which makes the shortcuts hints at the bottom act like buttons.

I seriously find that the shortcuts hints being always present to be very helpful, great UX for occasional fiddling with dotfiles and files in /etc.
Perhaps complete roll back to how it was in 2007 might do it. Among other things it would need to display items in a predictable order (e.g. in the order in which they were posted), and ideally do away with the 'wall' altogether. The front page could just tell me which of the people have updates (and how many / what kinds), and then I could check those out on their pages.

"would make me think that most game code is starting to move away from raw C++"

Godot is talked about on Hacker News but it's nowhere in the industry, as for C++ it's the default language for games and it will be the case for the foreseeable future.

I feel that there is a real disconnect between hacker news and people working in the industry.

Most people here don't seem to understand how different it is from your regular CRUD app compagny.
So then you're back to square one right? Where (apparently) the preference was given to DST (with its downsides), above sub-optimal schedules.

(Edit: Combining both your replies I think that may actually be your point)
It's not just that. Because it's all in the same repo and built with the same build tool it's also easier to run the same security checks you would use for your own code all automatically as part of your build process. All the tooling you use to secure your own code can be used to secure third party code as well with the same low level of friction.
At some point these transaction costs would effectively make further gains impossible.
Imitate, Then Innovate – David Perell
There have been a few cyclists who use whoop and it picked up on HRV and they could see that something was not right.

Hopefully HRV gets added to the AWatch soon, if it isn't already. (C'mon Apple, deliver my device!)

It is pretty cool that we can take these measurements and hopfully make data driven decisions. Hopefully in time we can use these measures to be prescritive and be guided to make better decisions.
From the article linked:

> Bacteria ~ 3μm while viruses ~0.025μm in diameter

However, SARS-CoV-2 is estimated to be around 0.1um, per https://www.ncbi.nlm.nih.gov/pmc/articles/PMC7224694/#:~:tex....

> SARS-CoV-2 is an enveloped virus ≈0.1 μm in diameter

Making the 0.1μm measure more relevant.

Ultimately, it's up to your judgement whether to determine these filters are likely to be at least as useful as alternatives, bearing in mind that a poor seal/fit (which you may get with other masks) reduces effective filtration by quite a bit.

Apart from the aforementioned testing of our filter material, and the third-party fit tests (https://narwallmask.com/#h:testing), the CDC's National Personal Protective Technology Laboratory, under NIOSH, is currently assessing the mask but has yet to release results.

Another option you could pursue is a half-face elastomeric respirator with a surgical mask securely taped over the exhale valve, coupled with tight-fitting goggles. It may be less convenient and may or may not achieve the aesthetic properties you seek, but those masks have been around long enough to be evaluated by government bodies for their ability to protect the wearer (though, not the public).
No you really can't. Gaming employs large amounts of people, sustaining economic growth as well as innovation (GPU development was originally sustained by demand related to gaming) . Bitcoin has little economic impact relative to its energy use.
I love this! As someone who recently left NYC for NJ to quarantine and who regrets not taking advantage of these restaurant experiences while in the city - have you thought about "pickup tourism?" Assuming things can be chilled for long enough, someone within a reasonable distance could drive into NYC to a distribution center near one of the tunnels, you hand off a bag at a scheduled time, they drive home, and enjoy their meal! I don't know what the parking logistics would be, and I personally might be a bit far to viably benefit (sadly!), but you could rapidly expand your range with minimal driver coordination, for everyone in the larger metropolitan area who would be willing to drive a bit for a one-of-a-kind experience. No other model could do this, because you need really unique inventory and a reputation for the same, but it's incredible that you've done that sourcing and negotiation!
> I think "for example" makes this sound more general than it is. List comprehensions are one of the rare few constructs that introduce a new scope.

The rarity of the construct doesn't matter honestly. Are you saying that list comprehensions should _not_ have introduced a new scope because it was unusual?

> The match block is more syntactically similar to if/while/etc. blocks, and so it makes sense that it would follow similar scoping rules.

Syntactically yes, but semantically it is very different and the semantics must be taken into account as well. The example given at the top of this thread (case 404: and case variable:) is enough to convince me that having variable scoping is a brain-dead obvious requirement.

> I think the complete situation is messy, but it's not the variable scoping rules' fault.

I agree with that statement. I think that improving the design/semantics would be more effective than just adding some more scoping rules in. In fact, I don't think this PEP should have been accepted in this current form at all. But given the current design, block-level scoping is appropriate. Given another design like maybe those you mention might not require that, but I think focusing on the fact that python doesn't have block-level scoping makes no sense. The python language before this PEP is not the same as the one after this PEP. The new one should have block-level scoping in this instance.
If it flew that often today it would have an impact, but it isn’t flying multiple times per day right now, and it will only be ready to fly its main mission when it can carry a fuel synthesiser in cargo — the explicit reason for its fuel choice is because it can be synthesised from atmospheric CO2 and water using solar energy.
> as bitcoin becomes more difficult to mine energy needs go up

Difficulty adjusts up and down as needed to maintain an average of 1 block every 10 minutes, it doesn't just tend to infinity.

It's mostly correlated to the block reward, miners won't spend more money on energy than they get back from mining blocks.

The idea of another Carrington Event scares me. All of our modern lives piggy back on an attachment to power and communications. Going without such for even a few days would devolve the first world into chaos.
Tesla carrying Bitcoin has two main motivations:

- to make money

- for the memes

Anyone trying to justify it with the merit of the technology is either delusional or trying to sell you something.
You Can't Have Marjorie Taylor Green and Mitt Romney in the Same Party
I am not sure I follow the logic. Bitcoin becomes "bigger" when there are more big actors not using it but just hoarding it? And thus less volatile - until one of these big actors decide to dump their holdings to the thin market used to trade only scraps left from these big actors... Sorry, not convincing.
They first need to switch their whole ads model to no-tracking contextual ads + remove private groups

Well, sure.

At the moment someone with a gun might stop me from going to have a cup of tea with my mother.

Nothing about Proof of Stake is relatively simple lol. Not the incentives, not the threat model, not the trust model, not the impact on the economics, not the implementation, not the scalable byzantine fault tolerate research.

There are plenty of people who understand it well, I'm not saying it's outside of reach of a normal human being. But understanding proof of stake is not a 30 minute journey. (nor is understanding proof of work for that matter)
"Lies, damned lies, and statistics" as they say. Serbia and Honduras are anomalies. Within the entire data set there's a significant positive correlation between "Guns per 100 inhabitants" and Homicide rate.
Decreased privacy for everyday users. Increased privacy for those with the time, resources, and incentives to find ways to orchestrate transfers that can't be tied back to them. In other words, the worst of both worlds.
Hopping up on my hobby-horse :)

No. An idempotent operation is an operation that can be applied any number of times without a change after the initial invocation. This means the first GET would fire and change state, but subsequent GETs would not.

GET should be nullipotent: it is an operation which can be applied any number of times without any change.
My issue with it is even more fundamental than this: it is structurally impossible for Proof of Work to become more efficient. If you find a more energy-efficient way to mine, the correct decision is not to reduce your energy usage, but rather to use the same amount of energy to compute more hashes.
...and the cost of those operations?
I think this is critical. The actual runtime of any code needs to do way more than what it’s doing now.

Simply relying on package signing and the like permits trusted but malicious actors. With Deno packages configured well it can really lock down and limit a ton of attack vectors.
Your comment is so obviously disingenuous. It makes absolutely no sense to open a Lightning Network channel to send one transaction and then immediately close it.
> C++ offers direct, low-level control over memory, and C++ can be used to implement anything which can be implemented in Rust. Maybe Rust has certain advantages which made this problem a lot easier to solve for Mozilla, and I'm certainly happy to have Rust in the language landscape, but another team with other processes may have been able to use C++ to achieve similar goals.

You could say the same thing about assembly programming or some language that uses GOTOs instead of structured control constructs ... or Brainfuck. Given infinite time and resources, you can implement anything in any language.

Claims about this or that language being unsuitable for a problem aren't really about stuff like Turing completeness, it's more about practical software engineering problems (e.g. does the language provide the right kind of support to the developers allow them to implement the required functionality in a reasonable amount of time with a reasonably small amount of bugs with the budget available).

npm link does not behave even remotely the same as a package installed from a repository, and there are quite a few packages where this does make a difference.

Another charitable explanation for the version selection rule is to allow specifying more than one mirror of the registry. Thus if the closer mirror has the latest version it will be used, but if there is a new version in the main registry that has not been synced to the mirror yet, the latest version will be used.
With a fancy tesla it might even be faster.
I like the latter approach: year-round DST. Not even sunlight in the evening is frequently a problem for me, but not enough sunlight in the morning isn't.

Show HN: Using ML to highlight unusual parts of S-1s for IPOs
If Bitcoin is the future and an antidote to the alleged extreme inflation of the US dollar, it makes more sense to buy the Tesla in fiat
You clearly don't understand how the Lightning Network works.
Tesla's not trying to reduce the number of cars, it's trying to replace the existing fleet with electric. This will likely increase consumption of electricity.

Wider adoption of bitcoin will likewise increase the consumption of electricity.

Electricity production (not consumption) is what causes emissions. More consumption will increase the demand for production, which will increase investment in production.

Given that we're in the middle of a green energy transition, increasing investment in production will likely accelerate that transition -- the stated goal of Tesla.
While you might believe that, the market disagrees with you.

They're talking more generally about cryptographic protocols which have advanced far beyond bitcoin.
Then you need to cache all files, which you were already doing years ago by cloning and browsing locally.

Bitcoin produces as much CO2 as a 737 does in a 5 hour flight, about 450kg, on average, per transaction.

Air travel is considered one of the biggest polluters, and reducing air travel is considered one of the highest impact ways that individuals can reduce their carbon footprint. It only stands to reason that Bitcoin should therefore be considered far worse for its impact. The only saving grace is that people don't actually use it to pay for much, else we'd likely be in a much worse place.

Edit: source is here https://digiconomist.net/bitcoin-energy-consumption - the 450kg was from 2018, it's currently 310kg (or 685,000 VISA transactions), 651kWh (or 22 days of household energy), and nearly 100g of electronic waste.

Bitcoin is essentially destined to be electricity price arbitrage in the long run, and that's a dangerous proposition.

Fantastic idea. I've looked hard for a tool to make nicer product marketing screenshots without a designer and there are very few nice tools. The best I've found is Screely[1].

Couple suggestions:

1. Be able to add a magnifying glass effect to draw the eye[2]

2. Put in different browser chrome

3. Allow annotations and arrows that don't look like they were made with a quick and dirty screenshot tool

4. Allow resizing and cropping

5. If you want to get fancy, build an OS X app to take and edit the screenshot in one go.

6. Add drop shadows and other effects

Paying for a tool like this above would save me so much time making product marketing screenshots and would be a no-brainer for me.

Sure there is - 'item missing' or 'order incomplete' both properly describe your situation, and I have had the same thing happen to me with amazon fixing the problem immediately.

Also, every time I've had an issue with an amazon order that I've needed a human to help with, I've been able to get one on the phone or via chat.
But he’s not allowed to withdraw the service if customers don’t agree. Therefore his business model, which was an exchange (not even taking users’ data, only displaying relevant ads), is required to become a donation from him to a good share of his customers, if he wants to keep the other ones who agree to advertising tracking.
The risk of horrible moiré comes to mind.
Every time anyone brings up a problem with Bitcoin someone says this. It seems like bitcoin is not designed for anything but existing.
what are you referring to?

off chain operations don't need to spend a lot of energy to validate transactions.

AFAIK globally the banking system estimated energy consumption amounts to ~100 terrawatt of power annually

that amount includes ATMs, servers and branch offices

EDIT: I forgot how touchy people on BC threads could be.

The data on energy consumption of banking system was cited from a post of a BC advocate

Statista has published data for transaction costs of 2020

https://www.statista.com/statistics/881541/bitcoin-energy-co...

What's interesting to me, on a human level, is the way people in the BC World keep moving the goalpost, one day they are greener because the total absolute power consumption is lower (regardless of users - I remember when in 2019 BC consumed more energy than Switzerland), then when it's not better in absolute anymore, BC is greener because is powered by renewables, like renewables were only available to BC miners, now that BC power consumption is going up (and fast) and banking is going down (slowly) it's ok, because it's the price to pay for freedom and everybody should be happy, even though they don't care about bitcoins etc. etc.

Funny, indeed.
