How is canva even worth that much? What's their revenue?
They aren't a general solution and don't really add much to your average application. But there are still instances where they make a lot of sense.

What I would need to see required before bothering with a message queue architecture:

* High concurrency, atomic transactions

* Multiple stages of processing of a message required

* Traceability of process actions required

* Event triggers that will actually be used required

* Horizontal scaling actually the right choice

* Message queues can be the core architecture and not an add on to a Frankenstein API

Probably others, and yes you can achieve all of the above without message queues as the core architecture but the above is when I would think "I wonder if this system should be based on async message queues".
I think lots of microservices can be replaced with a monolith which in turn can be replaced with a set of composable libraries versioned separately.

If anyone doubts that, this very browser used to read and write is built all the way up with dozens of libraries from compression, network, image encoding, decoding, video encoding decoding, encryption, graphics, sound and what not where each library is totally separate and sometimes was never intended to be used to build web browsers by the original authors.

Rest assured, most of the business (or web 2.0 systems, search, curate, recommend, surface etc kind of) systems are a lot more simpler then an A class browser.

> Presumably because loading will break?

I think the object will still load ok, I’m not sure if it would break because it’s been so long since I was in a scenario where I wanted to really delete a property. Normally when I make it obsolete there is also some new property or properties that have replaced it. When loading the object, if the (now obsolete) property is not null, I translate its value into the new property/ies (I.e., “migrate” it into the new properties), then null out the old property value, so that the migration only happens that one time.

I guess using something allegedly “simple”, over a long time, only appears simple because you will slowly internalise any idioms you’re using, and they don’t take much thought anymore.

Looking back — I’ve used this pattern for over 20 years, across various platforms. I’ve had a backing source that is anything from xml files to json to sqlite to in memory (for rapid tests) in a few languages. Things that seem natural or intuitive (to me) at this point are just habits that are rusted on, whether good or bad.

Sometimes I start building fast indexing systems on top of it, or archiving systems or record versioning… and the better tool would be to switch to a db or to a more full featured key value store. But it’s such a lot of fun!
solar power is getting cheaper by the day; https://www.pv-magazine.com/2024/04/19/europes-renewable-ppa... says:

> Energy consultancy LevelTen says that solar power purchase agreement (PPA) prices fell 5.9% in the first quarter of 2024, with decreases recorded in all analyzed countries except for Romania. It attributes the decline to lower wholesale electricity prices and a fall in solar module prices

however, they haven't yet recovered to the 02020 levels, presumably because the astounding precipitous fall in module prices over the last year hasn't been priced in yet

You nailed it. What do you do when you have cloud cover for two weeks in a row? It’s not unheard of when some areas have 200+ days of at least some cloud coverage.

Nuclear is essential to avoid using coal and not having regional rolling blackouts due to weather. Solar alone is not realistic anytime soon in all regions of the US.

> It’s not that obvious, as the brain grows, certain kind of cells die off and never come back.

I'm not sure what difference that would make. Those brain cells (and all the other brain cells that don't die off) were still formed by successive divisions of the single cell that resulted from sperm meeting egg. Therefore, that original cell is capable of producing any cell type found in the body.

When i try to consider what that really means, it leads me to think it actually encompasses a large and ever-increasing scope of features that have just become the norm. Browsers are becoming almost a general purpose OS.

Also, some of those features clearly require network effect to function which entails having it officially supported and suggested to the users (or even making it default).
I’ll never get behind solar as anything but supplemental or “roof top solar” until we have grid scale batteries that can power more than a few hours.

> No country has successfully increased fertility rates,

What's your point?

Ostensibly, modern countries have not yet suffered the predicted population crash that might incentivize more aggressive baby bonuses (https://en.wikipedia.org/wiki/Baby_bonus). This has been a thing for awhile (https://www.npr.org/sections/money/2011/11/03/141943008/when...).

It's a likely strategy to be extensively employed in the future, if the trends are realized. It's reasonable to expect there is an economic inflection point, where the program(s) would be successful.
My sense is the hype just died down. There are genuine cases where message queues are the correct solution. But since most of the developers are clueless they just jump on the latest trend and write blog posts and make Youtube videos.

This effect has also happened with microservices/monaliths, lambda/serverless, agile/scrum(still no concrete definition on these). Even cloud as a whole, there are so many articles of how companies managed to cut cloud cost to a fraction just by going bare metal.
I'm very happy with the safety of nuclear reactors.

I'm somewhat more sceptical of human nature, and the greed factor, when it comes to the proper disposal of nuclear waste.

I get there are regs for that too - but our track-record for following regulations when it comes to waste disposal generally has not filled me with confidence.

Costs incurred after the profit has been earned, (aka "cleaning up") are too easily avoided with a simple bankruptcy- and too easily corners are cut to just "make it go away".

IMO cleaning-up costs should be paid for first, not last. Ie the govt should assume they'll be stuck with the cleaning bill, and should extract that during production.
With way more money. ITER's budget is so far 22 billion. I would think development could be accelerated if they put more money into it. And I would argue that 22 billion for fusion research has the potential of doing way more for world peace than spending the same amount on defense.

I can't think of a single paper that would fall apart to any of its cited papers being retracted. What field of science operates that way?

Science papers are novel contributions of data, and sometimes of purely computational methods. A data paper will stand on its own. A method paper will usually (or at least should) operate across multiple data sets to compare performance, or if only on a single dataset it's gonna to be a very well tested dataset.

If MNist turns out to be retracted, would we have to remove all the papers that used it over their years? That's about as deep as a citation can get into being fundamental and integral to a paper. And even in that case nearly any paper operating in that dataset will also be using other datasets. Sure, ignore a paper that only evaluates on a single retracted dataset, but why even bother retracting, as the paper would be ignored anyway, because what significant paper would use a single benchmark?

But 99.9% of citations have less bearing on a paper than being a fundamental dataset used to evaluate the claims in the paper. And those citations are inherently well-tested work product already.

So if people actually care about science, they would never even propose such a scheme. They would bother to at least understand what a citation was first.
Battery prices have dropped 50% in the last 12 months.

Sometimes your product's value is derived from how much time each user saves using your tool. In that case, charging per-seat aligns incentives for both parties.

If Zendesk charged per-message or per-issue, then the incentive for the customer is to use the product less, creating less value for both parties. They would be eaten by a product that charges per-seat and optimizes for efficiency.

AI pushes the equation toward a local maximum, but it's a fallacy to assume it will reduce the number of seats for which you can charge.
Isn't that largely because of the regulatory burden?
Thanks for your comment! I do believe it depends on who you ask and ultimately both will co-exist. I also think low-code solutions democratize access to ETL development offering a significant productivity advantage for smaller teams. With Amphi, I'm trying to avoid the common pitfalls of other low-code ETL tools, such as scalability issues, inflexibility, and vendor lock-in, while embracing the advantages of modern ETL-as-code:
- Pipelines are defined as JSON files (git workflow available)
- Generates non-proprietary Python code: This means the pipelines can be deployed anywhere, such as AWS Lambda, EC2, on-premises, or Databricks.

I think that generative AI is a much bigger deal than the internet and maybe even the Industrial Revolution. The internet mainly sped up existing processes and made them accessible to everyone. We’ve had mail order for over a century, transatlantic communication through the telegraph and radio, and the printing press.

If the Industrial Revolution was so impactful because it boosted human productivity, then the ability to spawn hundreds, even thousands, of intelligent 'humans' at will must be an even bigger deal.

I think this says more about the guidance level than the soil quality. In fact I think it makes things worse rather than better.

Continually ratcheting up the safety level to spur continuous improvement is great in principle. But what I think this does in practice is mean that people are no longer able to evaluate soil lead levels appropiately. What does 400ppm mean versus say 1600ppm? They are both "bad" according to the US EPA now but one is clearly worse. If 10% of soil area is above your limit it is easier to allocate your limited resources to fix it than if 25% is. At 25%, with the same resources maybe you just throw up your hands and walk away from the problem.

There's similar problems with air quality limits. When the WHO says there is "no safe limit" they simulatenously misunderstand odds ratios and give a lot of people a great excuse to stop worrying about a problem they now think is unfixable.
Please re-read my comment. France's relatively small renewable fleet flooding their home market is a solution in search of a problem. If the goal is to decarbonize Germany in times of low renewable production inside Germany then we need interconnects between Germany and places high in renewables as well that are farther away from Germany than France. This is why Norway and Spain are good candidates.

France will have enough trouble rebuilding its declining nuclear fleet in the coming decades for their own energy needs, so any infrastructure that bets on France being able to supply neighbors as well will have a quick expiration. France is actually importing a lot of renewables in winter, because they heat homes with old electric heating (i.e. no heat pumps) and bad insulation that looses much more heat than homes in other countries and their nuclear supply can't cope with that.

In all likelyhood what will do the electricity decarbonization trick in Germany is threefold: more electricity transmission inside the country and with other renewable-heavy countries, continued quick buildout of renewables in Germany and a bit of battery storage, outlawing of coal and lignite in <10 years. The renewable gaps in the medium term will be fewer and shorter and will be filled with natural gas plants which are easy and cheap to build, even when they are just kept in standby most of the time. In the long term they will be made obsolete by even more lines and battery storage. Imported nuclear will likely play no relevant role at any stage. Like anything every bit helps a bit, but it won't change anything in the grand scale.

We already have a non-negligable amount of battery storage in German homes, but currently the incentives are laid out so that they will power these homes at night only. I believe we are loosing out on a bit of efficiency by not using it yet to feed back into the grid when needed. This could be enabled by smart meters and dynamic pricing in the future. It would also allow better to move household electricity demand into the times when renewables are most abundant.

> If this practice is so bad, why is it allowed for all other industries?

Competent lawmakers consider enforceability. Enforcing a law like this requires either the creation and funding of an enforcement agency, or additional funding to an existing agency to enforce it. If your law applies to all industries, that funding is massive and gets struck down--either the law simply isn't passed, or the law is passed but is a totally ineffective political gesture. There are rare exceptions, where there's political will to actually put together that funding (for example: ObamaCare), but then you run into the complexity of how such a law interplays with the various industries and parties impacted, and getting the enforcement of such a law right takes decades of tweaking and handling edge cases, which may never actually work.

Long story short, I'd much rather see small laws that target small, well-understood problems and fix them, than see unenforceable feel-good political gestures or some politician's magnum opus for his legacy that tries to do something too complicated for anyone to understand.
