Thanks for the criticism! We approached using silica from a different angle: we took a product sold over-the-counter in pharmacies & adapted it to climbing. This means we’re all good in terms of human product safety. The trick essentially is to use an aggregate of silica that has been tested before.

We think the trick to using less chalk is 1) switching to liquid chalk 2) using less chalk powder ... generally speaking liquid chalk uses far less chalk and last longer. Our crystal chalk is an improvement on traditional liquid chalk for those who want to use even less.

UPDATE: check the video I posted on our blog to see the diff between crystal and white chalk. Link in comment replying to OP.
I'd like to see both if possible. Actually I would like to see BCH replace USD (or a bigger block BTC).

I don't think there's a scarcity issue with electricity in places like Iceland where volcanic activity provides massive areas of land where electricity can be freely and easily generated. The issue is the ability to transport said electricity without massive losses.

> Perhaps because I'm one, but whether it's Magic the gathering, Demoparties, rubics cube solving, chess, Counterstrike LANs, academia, or any of my tech jobs, every "nerdy" activity I've ever engaged with has always been overly competitive.

I think that is little bit you choosing very competitive things to engage in. People who were obsessed with start trek for example did not build competitive societies. And I worked in multiple teams that did not felt overly competitive to me at all.

Low fees - but only once you're in the crypto ecosystem.

If you're after dollars or euros, the on-ramp and off-ramp at exchanges adds a comparable, if not higher layer of fees than existing payment mechanisms, kind of defeating the whole purpose.
Whenever you have a system where it costs several dollars to carry out a transaction, it will always be inferior to fiat.

We could bring microtransactions to the web, and replace a lot of advertising, if transaction costs were zero.
In addition to the replies, bear in mind that market cap is a bit of a fiction. If you go on a crazy buying spree to take over the network, you'll raise the price of each token in the price due to your own rising demand. It would be a lot more than $100B.

Breaks for projects of that scale are often negotiated ad hoc- the list break is more of an advertising move than anything.

I would bet dollars to donuts that if a mid sized company wanted to build a $30 mil data center, local and state governments would be willing to work something out, especially if the location would bring construction and long term jobs and other investments to an otherwise underserved area.
The FEC only gets involved over specific things.

If you want the FEC to be involved, you have to be able to say why they're involved.

Instead of giving a feel good story about what you imagine they're for, please provide an FTC-appropriate vision of what they could get involved over

It'd be like if I knocked a chair over, and you said "I'm calling the police," and I said "why would the police get involved," and you said "the police are there to protect us and our families."

That's nice.

What is the specific basis on which the FTC would get involved in this, please?
How many widely used Qt\GTK apps can you name if we are talking about general market and not just linux tools build by developers for developers?

I can name Krita and that's about it.

So... yeah, I guess finding a professional skilled in Qt or GTK might be problem.

And honestly - why bother?
Interesting analysis. Do you have any quick examples of site's that use LV? I'm curious.
A long time ago I maintained my own Linux from Scratch [1] installation using pkgsrc rather than BLFS or something ad hoc. It worked surprisingly well. It was a bit like Gentoo (whih is what I had migrated from.) Fun times!

I think it's mostly that Rust has a lot of energy behind it while and it attracts people who tend to be very capable and interested. Notably, [druid][0] and related projects are being worked on by [Raph Levien][1] who, well, I'll just quote his HN bio:

> I do research on fundamental UI technology and 2D graphics, with a focus on Rust and fonts. Currently on the Google Fonts team.

Rust also addresses many of my grievances with GTK and C++, notably the need to bolt on (although "bolt on" seems to imply less fragility than is the case) language features to give a higher level facade or otherwise deal with the deeply impoverished C and C++ build tools. Related to the previous point, Rust makes it much easier to bring in a dependency and write tests. Similarly, Rust benefits from a long tail of minor tooling improvements including documentation generation and hosting to text editor integration (Qt ships their own IDE which is of decent quality, but you have to go all-in on it; you don't get to use the plugins, keybindings, etc that you know and love from vscode / vim / emacs /etc and even then IIRC it only knows about things in the Qt project but not necessarily third party libraries--although with enough blood, sweat, and tears you can probably cobble together something based on clang metadata).

I’m guessing 2030 at the earliest. There are far more Intel macs out there than there were PPC and they have a long useful life span.

After that you’ll still get years on older MacOS, Linux, or Windows. Intel Macs can run both of the latter.
How am I saying anything of the sort? Regardless of when the people were born, it is a fact that they do not have a functioning government. It is a fact that Hamas derailed the effort to establish that government, and that Hamas has repeatedly interfered with those efforts over the past 15 years and continues to do so now. I am not "advocating" anything, I am simply stating the reality of the Palestinian situation today and why they are in that situation.

You seem to think Hamas is some long-past group. Hamas controls Gaza today; they are the ones launching rockets at Israel right now. Hamas remains the most significant obstacle to peace between Israelis and Palestinians right now. As the rulers of Gaza, Hamas has been a brutally repressive regime, roughly on the level of the Taliban in Afghanistan. Hamas deliberately spreads their military assets across densely populated civilian areas in order to maximize civilian casualties during war. The Hamas charter says that the role of women in society is to produce more men. They have cracked down on hip-hop, baggy pants, hair salons, and even indigenous Palestinian folk tales.

I personally think the Palestinians deserve better than Hamas. Why do you keep dismissing the overwhelmingly negative impact this group has had on the Palestinian people? Why do you keep looking for a way to deny the role Hamas has played and continues to play in preventing the formation of an effective civil government and a functioning Palestinian state?

This is obviously a completely bullshit statement. Bitcoin almost never works in places where credit cards or ‘fiat’ are accepted.

‘Fiat payments’ covers everything from the ATM network to cash to western union to Hawala. All aspects of fiat payments indeed have problems.

However the idea that today, Bitcoin solves these problems outside of a tiny fraction of contrived cases is a delusional fantasy.

Almost nobody in the world trades in Bitcoin. Almost everybody in the world trades in ‘fiat’.
You have a good product.

I have a weird feeling your target market will be females.

So many women are into climbing.

I don't have much advice except offer a percentage of sales to an enthusiastic hire.

I have a sister who owns a shoe company. She started with not much, but good taste, and is a very good salesperson. She is now a multi millionaire. Don't skimp on packaging. (You didn't). You are also selling your brand along with the product.

My sister started selling Doc Martins before they were a fashion trend. She knew American women would buy them up. Within a year of her working for the old stoggy company, she was selling more shoes than all salespersons combined. Her success was she is a salesperson whom believed in the product. She ended up making so much on commissions, the middle managers were scared. When Doc Martin lowered her commission, she started her own company. Find a salesperson like my sister.
That way everything is competitive. Pedantry does not have to be competitive at all.

By understanding the circumstances and work of the people you're managing, so that you can subtract confounding factors and separate their influence from everything else.

I used to be a strong advocate of 1Password, but I was also using Syncthing to synchronize my password database to multiple devices. 1Password basically killed support for that because they want people to pay for their SaaS offering.

Siglent SDS 1104X-E, same as in one of the photos.

In my case, the data was coming from cassette tapes, so the oscilloscope was absolutely overkill in terms of raw bandwidth by 3 orders of magnitude. However I was operating at its memory limit of 14 MSa (megasamples)... running at a sampling rate of 20 kSa/s, I had barely enough memory to grab the full 10 minutes of each tape side.

Its vertical resolution (8 bits) I was a little worried about, but the dynamic range of Differential Manchester/FM is so low it turned out to be a nonissue. Certainly the quantization noise is comparable to the noise floor of the basic-quality cassettes that my data was on.
Yup exactly everyone bought the trashcan mac (I have one now myself - I love these buggers!) and then were disappointed with the lack of expansion/improvement.

Everyone then bought the current Mac Pro, but were disappointed that nothing else really fits into the slots aside from the things that Apple offered themselves (Nvidia cards won't work in the current Gen Intel Mac Pros.)

What makes anyone think the next Apple Silicon based Mac Pro will be any different?

Wanting a more modular mac pro is more like wishful thinking or wanting something to be different when reality is clearly saying something.
Here's my advice after 25+ yrs dev't. Certain things make a job nice or not. Specific workplace and colleagues make huge difference. Poorly paid, "boring" work can be fine with super nice colleagues. Trying to chase faddish constantly changing tech (e:g js frameworks), is stressful and draining. Gradually becoming a wizard in the likes of Linux, command-line , FOSS, can be very fulfilling, you're your own agent, not at the whims of a vendor, and opportunities exist in many different types of orgs including public sector. Alternatively, maybe you could try some time out, even if just to work in a hotel for ski season or suchlike? That can give perspective. Some things are better outside of S/W, but many things aren't. If you see the grass isn't entirely greener, maybe you'll become content on returning. (I've done this). For learning, there's many free resources, college not necessary IMHO. One trick is pick a tech you really want to get into, play with it a bit then apply for underpaid jobs in that field. ;) Then after a while you can job hop if the pay doesn't increase cos by then you'd have experience. Working with a crowd that isn't all young, instead having a few older more chilled out less-to-prove colleagues can help :) Sometimes working in the least fashionable part of a company can have the most chilled people. For example QA. (well in my experience that was true)
So why put efficiency cores in the desktop processor at all?
They also shipped millions of faulty butterfly keyboards for years. So history tells me your confidence is misplaced.

> I am pretty confident that everything in that designed is planned pretty accurately.
Generally speaking, Apple's systems throw work like web browsing to the performance cores. Browsing the web is actually super intensive for very short periods of time, increasing performance of rendering makes the system feel snappier. They mastered this art in the iPhone as they had to learn how to make snappy feeling devices that also sipped power, the easiest way to do this is to be done with processing as fast as possible so you can get back to idling on just the E-cores.

The E-core magic trick is that they are always running and also exist to prevent thread stoppers, tasks that force you to pause high-priority work such as network requests, push notifications, or memory management. This enables a machine where the performance cores can pound away at tasks uninterrupted and your cache can stay dedicated to the task at hand, preventing situations where you may have to dump branches mid-process, increasing performance consistency. Mathematically, it works out to where the P cores are ~5.2W each and then the E-cores are less than that combined, allowing the system to idle on just e-Cores and spin up and dedicate P-Cores to the UI and UX intensive tasks, keeping the thermals low and performance high. In a situation like the Mac Pro, I would expect much, much hotter P-Cores too as the thermals will allow.
Cores aren't the real picture here.

AMD's high-end cores have a quarter-gig of cache. That uses a lot of power no matter how you slice it. AMD's Infinity Fabric interconnect uses 30-50% of total chip power. Apple will have similar communications overhead too.
Adding more memory lanes increases power consumption as does adding more PCIe lanes and other IO.

It definitely remains to be seen if their chips are significantly faster when scaled up. In any case, they wouldn't have to beat AMD or Intel to count it as a success. Simply not being terrible would be enough.

I think you're both arguing the same point: that monopoly markups can negatively impact consumer welfare.

The central argument is whether Amazon specifically is a monopoly in any of the industries in which it operates, so as to be able to charge higher prices you speak of — that's not what's happening.

In fact, the GP comment laid out exactly why vertical acquisitions often improve consumer welfare, in the case that the company being sold is itself a monopoly:

> And indeed, in the Apple hypothetical you could well expect consumers to be better off and for exactly the same reason: if Apple purchases an input (the M1 chip) from a monopoly supplier (the hypothetical non-Apple-producer), vertical integration removes one monopoly markup.
I noticed this as well and if I am honest it is a tiny bit annoying when the app is open in another workspace it pulls me to it instead of pulling the app to the current firefox instance. This forces me to bounce back to whichever workspace the firefox was on. Not a huge issue though.
Moving from 1Password to Bitwarden was the best thing I did.

Bitwarden enabled me to use it with Linux, Mac, Windows, Web, etc. _years_ before 1Password decided to join the party.

And there's no subscription to speak of - just a premium "extra features you may or may not want" yearly payment, which works out _much_ cheaper.

Finally - all my passwords belong to me. Self hosted server means that I keep control, not some random cloud.

After reading some of his books, essays and hearing people talking about him, I think Graham is first and foremost a nerd and hacker, the other stuff is secondary.

It could be as simple as timing, the polar stroking paper probably hadn't come out at the time this paper was written.
I really like this idea, but I'm not sure if it would work in practice. It's basically working against webpack's code splitting because those are tagged with hashes. Additionally, the first load will still be quite heavy, whereas with code splitting at least there's some semblance of a smaller initial load. Since it's not native to the browser, it would have a nontrivial initialization overhead as well.

I think it could be a cool idea if it's offered as a static file hosting as a service kind of deal that requires zero config, but then again if you're the kind of person that wants a zero config static file hosting, you're probably not pushing daily/hourly software releases?

It would be neat to have something like this more transparently implemented though. Seeing a 2MB+ module rebuild for a minor typo fix is aggravating.
To quote wikipedia:

> Ethereum is a decentralized, open-source blockchain with smart contract functionality. Ether (ETH) is the native cryptocurrency of the platform. It is the second-largest cryptocurrency by market capitalization, after Bitcoin. Ethereum is the most actively used blockchain.

It's a blockchain whose token wasn't intended as a cryptocurrency but as a medium for paying for having a program ("smart contract") stored on it run on every node of the network. In practice this can be used for all sorts of things, including bootstrapping the vast majority of other cryptocurrencies currently in existence, but under the current system it can't process transactions effectively enough to be useful in that manner.

As I understand it Ethereum 2, which is a really long term thing they've been doing for years, is meant to gobble up the original Ethereum completely once all stages of deployment are completed (any prior forks that may happen would remain independent, I guess).

I recently upgraded to a Pixel 4a from an iPhone SE and it's convinced me that, in fact, Google is really good with software when they have the opportunity to program directed against a set SKU. Performance is really good on the device, it's functional and doesn't get in your way.

As for the article, TBH, I think the Pixel devices don't do well because of aesthetics of their phones. This is something that Apple does really well.

Take a look at the recent leaked photos of the Pixel 6. IMO, it looks.. not so great. I'm not surprised that people choose iPhone over Pixel, especially with the iMessage effect, longevity of the devices and overall design.

The Pixel 4a is probably the best phone I've had. Google could have something really great if they actually stick with it for the long-term.
>Easier to keep changes small and local to the code changing

When refactoring code in a statically-typed language, the programmer must do extra work to satisfy the compiler, perhaps even changing code elsewhere in the program.

>Unit tests need less boilerplate/mocking/stubs

In a dynamically-typed language, if the code under test calls a method on another class, that's the only method that needs to be mocked. If the language were statically-typed, the entire class would have to be mocked or at least provided with stub implementations of the methods not called.

You can see examples of the kind of extra work a statically-typed language requires in Kent Beck's book on Test Driven Development, where a class has to be changed from abstract to concrete just to satisfy the compiler.

Also, I'm glossing over some of the additional dimensions of typing, like strong vs weak and manifest vs inferred types. Different languages have different requirements.
I agree. The implication is the opposite of reality, and I can't help but feel it's intentional.
