You say, "Modern Pozzolanic cements, more similar to the Roman ones, are in practice very rarely used".

Wikipedia says, "Over the course of the 20th century the use of pozzolans as additions (the technical term is "supplementary cementitious material", usually abbreviated "SCM") to Portland cement concrete mixtures has become common practice. Combinations of economic and technical aspects and, increasingly, environmental concerns have made so-called blended cements, i.e., cements that contain considerable amounts of supplementary cementitious materials (mostly around 20 wt.%,[clarification needed] but over 80 wt.% in Portland blast-furnace slag cement), the most widely produced and used cement type by the beginning of the 21st century.[5]". https://en.wikipedia.org/wiki/Pozzolan

Who's right? Are pozzolanic cements "the most widely produced and used cement type" or "in practice very rarely used"? I'm guessing it's the writer who doesn't think "pozzolan" is a proper noun in English.
Hmm, I'd always assumed that most of the energy from burning natural has came from the oxidation of the carbon, not the hydrogen, but maybe that's not the case.
I'm curious, as I have never asked the question prior ; What is the canonical "unit test" whatever [method|practice|technique|whatever] that one should know?

Is there a place where tests/unit-test-methodologies are discussed, or codified?

How learn?
Agreed. It's pretty crazy seeing posts on Facebook, Twitter, TikTok and Instagram with hundreds of thousands of views on them while most of our posts are lucky to be seen by 10 people... There is not much social about that at all.

Apple do appear to be trying a bit harder with Safari - since the regulatory heat has turned up, they've started releasing Safari more regularly since v15, and adding more new web platform features. Safari still does have its problems but I don't think it's fair to say Apple are letting WebKit stagnate.
The browser APIs in question handle that aspect. Check out the linked demos if you're not sure what that looks like.
If you break down the muscles involved, it’s not bad. Squats are quad, glute, and back dominant, so you would balance with exercises focused on hamstrings, hip flexors, and abs. Also, tons of stretching.
Strong resemblance to the ESP32-C6[1], which was announced a year ago & never shipped (from what I can see). RISC-V, Wifi6+BT5.0. 5GHz support is new & great to see; let's hope this one materializes!!

Projects. Build (non-trivial) things and put them online. Write about them or make a video. It takes a while to build up a collection of these projects, so start now. But, when interviewing in the future, point to your list of projects to demonstrate that you are so committed to coding that you do it for fun, and you will be surprised at the interest that companies will have in you. You might even find some freelance gigs to give you more experience.

This strategy worked for me many times!
Why? They clearly explained how it works for them. What's funny is you not being open to new ideas. That's a worse sign for us all than Copilot.
Is that true for Boomers, or was that mostly true for the Silent Generation (those born 1928 to 1945)?

My experience of Boomers (my parents and their friends are early Boomers) is that most of them were working as two-income families, whereas my granparents' generation (late Greatest and early Silent), it was much more common for there to be only one outside income coming into the household.

SSO is not the only method of authenticating things. They have auth keys specifically for the purpose of authing headless servers. e.g.
sudo tailscale up --authkey tskey-abcdef1432341818

You can also apply an ACL tag to it so that it is no longer authorized as the user and instead takes on the permissions of the tag.

In our deployments we have the headless servers pull the tagged auth key from secrets manager on boot and then just `tailscale up --authkey <value>`.

I agree the default login flow is usually not what you want for headless servers. It sort of leads you down the wrong path.
Hmm AFAIK you don't need a bastion to use SSM agent - it even allows you access through the browser. I think you meant EC2 Instance Connect which manages temporary SSH keys.

Actually, this is inaccurate[0] and I think it's rather incredible that it was accepted uncritically. It seems that you particularly dislike vaping, but aren't very familiar with the science. Personally I would not be telling people what they "should. not. be" doing without even a basic understanding of the subject.

Not only is the blog post black and white, the comments here are similar.

We have not leveraged yet the potential solar and wind have. They are easy to build easy to understand, make you self sufficient and are now the cheapest option from all.

In parallel there are plenty of countries who have lots of space and uran and could do more nuclear (ignoring the storage issue).

And geothermal is a good option in plenty of countries as well.

But funny enough people still think that nuclear IS THE solution while ignoring that the thorium reactor is still not viable, that we don't have enough uran and that they are highly dependent on water for cooling which becomes a big problem in the summer for plenty of countries.

Let's finally stop talking about our future energy mix and trying to do the best option for were you are.

We need to get a ton of energy changed from high co2 production to the lowest possible very fast.

And btw. Whoever this dude is he is probably not someone who would be able or allowed to build a nuclear reactor so his best option is probably to still be in the solar business.
Not necessarily, because once the result has been generally has been rolled out, you've started altering the population your experiments are drawn from.

No amount of short-term testing will discover [*the cause of] a long-term decline, if the long term response of the system of customer/product/company is swamped by an opposing reaction in the short term.
I said 500+, not 2000. If, 500 years from now, the best 25% of structures built by us remain standing, I think that's a good thing.
It's on the other portion of FIDO2: CTAP, short for Client to Authenticator Protocol. Your authenticator (A TPM, a YubiKey, maybe a phone) verifies your biometrics, pin, or presence before signing a request for the client (the browser, in the case of WebAuthn).
Udemy coming in at 66% is pretty surprising to me. I personally purchased some 50 courses on there, and am happy with the result (especially owning the course and not having to deal with a subscription), but it is surprising to me that it basically won that market. It isn't all that friendly to course maker iirc. And the course quality varies a lot. Its pricing model is also very shady, giving me the impression that it is a poorly run company.

Of course - youtube is not included; I imagine that'll really skew the graph

edit: shoot, I just checked and I actually purchased 98 courses.
> Upgrading coal to gas is a great intermediate step. However, it’s not a long term solution because natural gas reserves are limited. Plus, many countries have already done it.

I don't see the author as arguing that we should all switch to natural gas.

Rather, I believe that they're trying to illustrate what they view to be a idealistic flawed thinking pattern ("utopian energy" or "green energy maximalism" or whatever you want to call it) and calling for a more rigorous and empirical engineering-like approach where a much larger trade-space is considered - even if that new approach leads to exactly the same conclusion/solution.
The statement was about whether some vapers graduate to cigarettes, which seems completely unrelated to whether some high school kids vape (what you stated) which is trivial to verify is true.
The idea that a flavor like bubble gum is ~only~ attractive to minors seems wildly off-the-mark to me. Adults enjoy bubble gum, and also enjoy flavors that are not tobacco-like.

I've never paid attention to Juul marketing, so perhaps they were committing faux pas in their targeting, but the existence of a bubble gum (or other enjoyable flavors) should probably not meet the threshold as readily as we allow it.
As a French native speaker I find it even weirder. How is "libre" even pronounced in an English name?
> But seeing that their software barely works outside of their platform, it's a miracle they have any customers at all.

I don't think very many of their customers run any of their software anywhere other than on Macs and iDevices, so I expect that doesn't have much effect. Aside from the apple TV app on Roku and various TV operating systems and such. And still, none of this makes Safari not an "actual browser".

This sounds exactly like my Cisco (anyconnect) VPN experience from a previous job/life, both before and after Okta was introduced... we think it don't be like it is, but it do.

This is a stretch. The difficulty of losing weight might be related to genetics and the environment and monetary capability, but it is 100% possible for every person on this planet to lose weight. Bodies cannot create calories.
The COW and short string optimizations are not mutually exclusive. If we assume short string optimization is implemented both before and after, then we are back to comparing the atomic increment to allocation. And different allocation approaches can make the cost of heap allocation differ quite substantially. I'd fully expect that some allocation approaches are cheaper than the cache line invalidation from atomic increment, but some others that tend involve a lot of pointer chasing can be rather costly.

Certainly plenty of widely copied strings are short strings, so a COW implementation that lacks the short-string optimization could very easily be a bad bottleneck for multi-core compute.
Interesting to combine this line of thinking with the transition from nation-states to market-states:

https://www.tandfonline.com/doi/abs/10.1080/1744057060106386...

The power vacuum that's arisen from populism & isolationism is about to create a gigantic untapped market for firms that provide the services of a state - defense, dispute resolution, and currency - for a fee, to gigantic multinational corporations. At the same time, there are nascent technologies (drones and robotics for defense, blockchain and the Internet for dispute resolution & currency) that dramatically lower the cost of many of these services, to the point where we may see private companies that are more effective than nation-states at it. Might we see the nation-state get replaced by a web of competing mercenaries, each of which effectively serves as a protection racket for their customers?
I believe that Stack Overflow belongs to a time when VCS was the exception rather than the rule, codebases were scattered across many different providers, discussions took place on dedicated channels or mailing lists, documentation was scarce and of poor quality, and tooling was limited to the most essential. All this added friction to any form of shared knowledge of being built by the general public.
Interesting as always. It would be great to have a UX to easily compare the trends, such as 2022 vs 2021 vs 2020 though. Unless I missed it.

The "Web framework and technologies" section doesn't seem accurate to compare in a meaningful way.

For example, they have Node.js as a standalone option probably throwing off everything. Then these compare weird when put together as options: Next, Nuxt, React, Vue, etc.

Love it or hate it, jQuery was also #3.
I don't know how to phrase this but this feels like a lot of truisms / a few reasonable possibilities and then some pretty BIG leaps as far as predictions go.

> It is extremely common for an executive to come in and start off with bold plans to improve things, then slowly discover why things are the way they are.

The same is true of a new IC coming into a new code base.

The things you mention are not great excuses for not being able to make any change. If those things overwhelm an exec, that exec should probably step aside and let someone else try.
Yeah paid upfront and zero marketing won't get you far anymore but that's true everywhere in software now.
> I read this as the author wanting to decouple as many things as possible

Nope. This was actually created incrementally, starting with YAGNI/DTSSTCPW, adding elements only when they became absolutely necessary and actually removing a lot more code than was added, despite becoming much better in quality and performance.

The one big thing was that the additions were not limited to the architectural preconceptions we currently have.

And then there was a lot of serendipity. This was not what I had set out to build ... it turned out way better.

> risk of the UI flooding

It turns out that Blackbird actually prevents that exact scenario, in fact that was the main reason for reifying the update events in the first place. And it worked pretty much perfectly at that.

> ... lose techniques for coordinating dependent changes.

Not our experience.

> Highly decoupled architectures are harder to debug with traditional tooling

Might be the case generally, we did not find that to be the case with Blackbird. I think that was largely because the elements were both very simple and so incredibly easy to test individually that we got very few surprises in the composed results.

But you can and do, of course, still test the compositions as well. Hexagonal architecture For the Win!

> The decoupling introduces a break in the trail, like a fugitive slipping into the river to shake off the bloodhounds.

Again, not really, as the model, where the functionality/complexity lives is pretty much exclusively synchronous. The parts at the edges where asynchrony is introduced are generic and largely functionality-free, they tend to not change with new functionality and thus not be the source of new bugs.

And of course you can also test them independently.

As an example, the code path for performing all requests is completely generic. The only parts that change are the PI to URL translation and object serialisation/deserialization, and those are local, functional and easy to test without all the other machinery. Once that works, the confidence that it will also work with actual requests going over the wire is close to 100%.
Somewhere Between a Jeremiad and a Eulogy (2017)
So the supposed lesson is that generic third party APIs are hard to mock, so you need to write helper methods everywhere so you can mock those instead?
I believe the most sustainable and fair payment model is paid app at version X, which will get bugfixes indefinitely (or for a long time at least), but no new features. Later a new paid version comes out that will contain the new features, but that way existing users that find the previous version they paid for enough can continue to use it, yet the developer gets a steady stream of money as presumably many of the users will buy the newer version.

See the Reeder app for an example.

Though this doesn’t work where service fees are part of the equation, perhaps the best way to handle that would be passing the cost down to users through an optional subscription.
> For a small business, what is so hard about keeping a file (CA private key) secure and changing it when required?

For a small business? Well, keeping a file secure and changing it when required ^^'

I mean, it's not out of this world hard to generate your private CA but there are a thousand footguns, the experience isn't exactly friendly, and it's Yet Another Thing To Do And Keep Track Off, i.e even if there's someone who has the technical chops, they may not have the bandwidth, and also, lottery factor. Let alone keeping it properly secure. There's a whole framework/procedure to create to set that up properly.

A major point missing is growth in overall energy usage. Developing countries tend to be in places with good conditions for solar, and there isn't an entrenched idea about having a huge share of 24/7 "base load".

US startup folks seem to think they should work quite a bit harder in terms of time and more importantly in terms of intensity. EU folks seem to think the intensity should be lower.

My limited experience suggests intensity loosely correlates with success, but is dominated by chance.
This is just false. Go read the literature on nicotine. It helps create artery disease, both in terms of blockages and having them explode (hardening of the arteries) later.
Everybody knows that some teenagers vape. The question is whether vaping (which has minor health affects) is leading people into smoking (which has severe health effects.)

This is already true. iPhones, and Macs for the past few years, are so integrated with iCloud that losing access to your Apple ID is going to give you a very, very bad day. Apple clearly recognizes this with their work on physically pairing devices via iCloud.

WebAuthN is, on the whole, a very good thing. Cross-browser authentication that gets lifted up to a biometric or token level will reduce the vast, vast majority of customer support and friction to creating accounts. Additionally it reduces the dependence on OAuth2, having to "register" applications and requiring customers to remember "did I use Google to sign in here? Did I use Facebook?" etc etc.

According to the description this adds at least 660ms of latency, so might be useless for certain applications. Wonder how much the TFA solution adds.
My reading of your comment was that you were piggybacking on the above:

> Build a few big underground atomic bunkers around the world and store the long term waste there until we can find a solution (or leave it there).

And your comment specifically mentioned Yucca mountain, which was indeed planned to be a big underground repository for nuclear waste, and therefore vulnerable to the same type of catastrophic failure I referred to above. Am I missing something?
I've done something similar to this, though in a React Native world, where ReactiveX frameworks are a common enough pattern that this really seemed like the most obvious way to do it.

I think the terminology that made more sense to me at the time is CQRS - instead of treating everything as a synchronous query/mutation, mutations are expressed as commands, and the expectation is that their effect will be reflected in the UI and on the backend asynchronously, but of course in the UI much sooner than in the backend.

The tricky part is that CQRS comes with some requirements for careful data modeling - you need to understand how your mutations compose across time, and like `swatcoder` mentions, you also need to use some unusual techniques for composing/coordinating operations across separate entities.

That said, it led to a fantastic user experience and additionally provided the benefit of 'solving' a whole host of issues around idempotency that turn out to be surprisingly common problems on mobile platforms because of missed ACKs from the server.

It’s by no means a given that wind/solar will be a major source of energy for the long term. If we’re lucky advancements in wind/solar and energy storage will make it a big part of our future energy supply. If we’re unlucky we’ve spent many trillions and made very little headway towards a more sustainable future.

Maybe the solution will turn out to be molten salt nuclear along with synthetic oil and carbon capture. Maybe something else altogether. Who knows, it’s still early.

I don’t think we should presume solar/wind will someday take over, and I’d like to see an “all of the above” energy strategy instead.
Nah. It sounds like personal transportation without the overhead of ownership, maintenance, time wasted waiting for the bus, etc.

If there's an underutilized resource in the First World, it's automobiles. They probably spend on average 22 or 23 hours of 24 hours doing nothing. Just sitting there. Uber-izing your own driving could change that, without exploiting under-paid drivers.
Some of us have read Bastiat (in French!), Mises, Hayek, Rothbart, Solerno, and other "heterodox" Austrian economists, and have a better understanding of how money arises and how central bank interference in monetary and credit markets creates the boom and bust business cycles.
