It's not critical, but I think you are looking at the wrong page. $55 is on the /MW basis, the next page shows $131/MWh which is still good.

The source is "Lazard estimates", but I can't find anything close to this in reality. Pumped hydro is meant to be super cheap, but is currently ~ $100/kWh. I'm starting to agree with the other commenter that Lazard is bunk.

"Pumped hydro is already the cheapest energy storage technology in the world in terms of cost per installed kilowatt-hour of capacity. Total project costs range between $106 and $200 per kilowatt-hour, compared to between $393 and $581 for lithium-ion batteries, World Bank figures show."

Sure. Shareholder interests and all that. But regardless of the reason why companies might be fattening up (come on, do you really believe they'd leave money on the table even in the best of times?), the fact is they're doing this at the expense of American households. That doesn't make it hunky-dory. And to bring it back to the original topic, that too is inflationary.
I kind of hope one day personal data plans render public wifi obsolete. Every time you connect to a new wifi network you just never know what awaits. It might be a slow connection, it might be a shitty device that only kind of works, it might be a security nightmare… Wouldn't it be great if all our devices, laptops, tablets, mobile phones, had digital SIMs and we could just purchase a single data plan for all of them!
Ah sorry, I thought you might have been responding having read my entire post, which gives context to the first two paragraphs.

I mean first gen Graviton was announced in late 2018 during reInvent. And it wasn’t even generally available until mid 2019. It was underwhelming, but layering some required software foundation. Graviton 2 was in late 2019 and wasn’t GA and available in many region until 2021.

Lazarus on the FreePascal compiler does exactly that, borrowing from Delphi's heritage. It copies VB6 almost literally, in many ways, but can output binaries for win/mac/linux.

I've written a few toy apps in it and in my limited exploration it seems to be a joy to work with, once you get used to Pascal's quirks... and I'm not a fan of the ancient MDI workflow it imposes either.

I also learned to program with VB and Lazarus is the closest thing I've found. The WinForms designer in Visual Studio would be the next closest.

Both GTK and Swing have various GUI designers that are similar, but have their own design and use different layout metaphors. If you're looking for a more modern take on what's left of RAD maybe check them out.
I was also surprised by that but there may be some slightly unusual background reason for that that simply doesn't get mentioned. Superficially it sounds like the author should just... do the HTTP request? Since they're waiting for the response anyway

People always look at me like I'm crazy when I talk about non-24. If left to my own devices I'll just go to bed an hour later each night, I can get into a bit of a midnight to 2am schedule also, but then pop a later night in order to be tired enough the next night to rest back a few hours.

Also recently diagnosed ADHD (in my 40s), and apparently sleep issues like non-24 are at least correlated to it.

I'm not so sure about that. I suspect the mismatch in labor participation rates pre vs. post COVID is mostly accounted for in early/normal retirements. All those boomers that they were warning were going to eventually retire just happened to do it at the same time. They won't be coming back to the labor market.

Anecdotally between my parents, aunts, and uncles I have eight relatives who retired in the past two years (between that ages of 55 - 65).

It can certainly be a component in the pipeline but even when you have a bunch of dedicated raytracing hardware it can be hard to get enough data to be worth denoising. Nvidia RTX cards use a combination of all 3 (dedicated raytracing hardware, traditional GPU compute, and dedicated neural compute) and still even the high end desktop cards have to be teased to get acceptable performance in non-trivial raytracing demos and games.

Where the M1 Max GPU really shines is having 64 GB of high speed memory. Any other scenario and it's really not all that special a laptop GPU in terms of performance or ability, contrasting to the CPU which is can be quite impressive in both regards even when compared to desktop/fixed workstation class options.
The WISPr[0] standard was created for this purpose, and is (or was by now?) used by companies such as iPass to their customers to transparently log in to most WiFi hotspots. I don't think that standard is accessibly anywhere these days. I made a Python implementation [1] that should still work.

In the Windows desktop world, you can understand a lot by realising that Microsoft developers almost never install and configure Windows "from scratch".

They're given a preconfigured machine with a standard operating environment (SOE) image that has many small tweaks preconfigured. This is then connected to Active Directory and managed through Group Policy, which sets a bunch of configuration settings to sane values.

In other words, the people developing Windows are using it like 10% of their customers do (large enterprise), not like 90% of the customers (random individuals for home PCs or small business).

When I first realised this, a lot of little things suddenly "clicked" and made sense...

Some random examples of this:

Practically nobody at Microsoft gets given a PC or laptop with a HDR screen... so Windows does't do HDR properly.

Practically nobody at Microsoft has to worry about backups (it's centrally managed), so the backup capability built-in to Windows is trash and constantly broken and/or left to rot.

Everybody at Microsoft is "well connected" to the Azure cloud, so they assume every else is. Why not backup to One Drive? Uh.. because I'm satellite internet in the middle of nowhere!

Microsoft developers don't have to manage the SOE and its deployment process, so the tooling around this is... "not great".

Regional options, location, time zones, etc.. are all preconfigured and valid, so nobody at Microsoft thinks about what happens in "complex" cases... Like non-English-speakers using their products. Or being anywhere outside of the United States.

Alternately, if wind and solar can be made absurdly cheap, there are are less-energy-efficient but lower-cost per unit output forms of storage that can help. Pneumatic storage is promising for this for example. So like instead of one wind turbine and one battery, you build two wind turbines and one pneumatic energy storage vessel and get the same amount out.
Almost twenty years ago, I was on a team that built a bunch of health care apps where we had significant, robust mainframe business systems that we needed to get in front of both internal staff, external providers, and the public. So yes, those systems definitely used a whole lot of messaging and in my career since I saw repeats of those patterns not only in that industry, but also financial services, telco, and lots of other places I stopped along the way. Anyplace you’ve got hulking business systems with lots of rules, it’s common to have messaging in between there and the web, and for various distributed applications to talk to each other.
Your question was "How did the 13th amendment codify slavery?" They answered it, the first mention of slavery in the constitution legalized it for convicts in the 13th Amendment.

Why are you now changing your argument to "they deserve slavery?" Didn't you just say the Civil War ended slavery?
You raise some genuine possible concerns but generically I'd probably tend to just say, "laws will stop them" just like they already stop someone deliberately endangering lives by placing a real fake stop light in the middle of the 101 at rush hour.

The real concern would be whether someone can engineer a terrorist level mass scale attack but as long as it requires physical tampering that adds up to a tremendous amount of work. So if the signalling is largely burned into fixed infastructure it eliminates a lot of that or at least sets the bar high enough that its probably more work than various other types of attack that are likely to be just as impactful.

And just like on the internet, extortion by incumbents along that route can happen, and likely will once there is an encumbent Lightning wallet provider that is too large to ignore for merchants. (All assuming Lightning or something like it is successful in the first place, of course.)

This is plausible. Lightning Wallets are harder to run in a self custodial way rather than classic Bitcoin on-chain transaction.

> In a typical online payment scenario, the customer is the sender. Of course large wallets could strike deals with merchants to let them cover fees for their users to make this less apparent...

Wallet providers could turn in payment processors as well for merchants.

Not familiar with this concept, I know that it exists. Though the cost of establishing that system is mountains more than establishing a channel to your favourite bar. But it is a micro optimisation.

I'd say this is a good introduction into reasons why self hosting clustered software is not something to do lightly. He's basically running rabbit mq on Windows. Yikes. And also, why? I'm sure it can be done responsibly. But allowing all nodes to self update and reboot randomly sounds like amateur hour to me (that actually happened apparently).

So, don't do that. I don't use rabbit mq currently but we do use Elasticsearch, which has similar clustering capability and used to be more susceptible to split brain situations (been there, dealt with that)

These days, I recommend using Elastic Cloud and avoid self hosting it. It's only cheaper until the first time you have to deal with a split brain cluster because you botched an update, mis-configured it, etc. One of the nice features in Elastic cloud is that you can click an update button and it will orchestrate a rolling restart. If you don't know what that is, you should not be operating a cluster of any kind.

I'm sure there are similar cloud based services for rabbitmq. Probably well worth the money unless your in house ops team is super experienced with operating it (which clearly wasn't the case here). Such a team would cost you many hundreds of thousands of dollars per year. One person does not cut it. You need at least a 3 or 4 so you can afford them taking vacations, sick leave, leaving, or dying in some tragic accident. Half a million pays for some pretty nice cloud based clustering capacity. A good team will cost you more.

For reference, we pay about 70/month for a tiny Elastic cloud search cluster that is actually good enough. I can double the price and capacity with a simple slider and it would still be cheap. One hour of my time is more than that with my normal freelance rate. My monthly rate would pay for an enormous cluster that far exceeds anything we need and it would still be cheaper than making sure we have four people with my skill set in the team (we don't) able and willing to look after it at all hours. The largest cluster I've ever dealt with was a self hosted monster that could index billions of documents per hour (millions per second). You so much as looked wrong at it, all hell would break loose. That cluster was one of several managed by a very experienced ops team that probably cost millions per years. That's the price of doing business at scale when self hosting.

Most companies running into trouble with ES cut corners on doing it right and then pay the price with preventable outages, scaling issues, technical debt, etc. Cloud based services don't completely prevent this but if you know what you are doing, they provide a nice level of safety and risk mitigation.
> Patching/updating software on a machine should be a matter of spinning up...

While this is absolutely a "best practice" I really think there is a pretty big divide here between the best practice and what happens In The Real World (strictly by number of developers). Between $DAYJOB, consulting/freelancing, and the internet/tech twitter/HN/etc, I've seen basically three groups:

1. FAANG, startup, etc. that probably follows this best practice "cattle over pets" methodology more often than not. 90% of developers do not work here. For the same reason you can't compare FAANG salaries to really anything else, you can't compare their tooling and infrastructure either. They're playing a completely different game than most people.

2. Indie developers who want to mess around with this stuff.

3. Boring companies with IT departments where you have to request VM resources and wait for them to get spun up. I worked for a place within the last decade where the idea of getting a VM provisioned for you in less than 2 business days was laughable. This was a publicly traded, multi billion dollar company with probably 800 developers, IT, and support desk folks on staff and did not make any money from its software directly (we were not a profit center).

I am considerate of the "well you should just" mindset when it comes to dev ops and infrastructure, but most developers don't work in that environment. If the company has never had that sort of expertise or expense before, it's a hard sell especially if it's coming from a developer who has never worked in that environment before. And truthfully, the last thing I want to do as a software engineer is become "the devops guy" and now be responsible for the VM infrastructure of the entire team rather than actually writing code.

Not just deliberately trying to force a narrative... trying to force a narrative that is contrary to what is commonly accepted to have happened, specifically because their new narrative benefits them financially, politically, socially, or in some other way.

A "revisionist historian", as I understand it, is a manipulator, a con artist, a gaslighter. Someone who is trying to convince people of some history that didn't actually happen, because doing so will enrich them.

> I'd rather try to build a four story brick building with horse dung for masonry mortar, than run my backend on windows boxes. How many cumulative hours of horror has Windows Update unleashed on the human race?

+1

War story: an ex-client of mine was on a different continent demoing a product (involving a physical device talking to a software backend hosted by a partner company) at a neutral site to a potential new customer.

Months and months of talks and prep, dry run demos in the weeks before, everyone was quietly confident. Scope for selling lots and lots of these devices if the demo goes well, but the marketspace is fairly ruthless.

Minutes before the team are due to present, a sudden and total comms loss between the device and the backend. Cue frantic calls which due to the time zones even involved getting the CEO of the partner company out of bed. Minutes ticking by..

Potential customer not impressed, said: you have ten minutes, after that we're leaving.

As the potential customer was walking out of the building, the partner company finally tracked down the issue.

You're thinking of QA testing. Beta testing is the final stage of testing before release and aims to test the system in as close as realistic environment as possible - that's why betas are often seeded to the general public, you want to find out if your system doesn't work on some configuration or circumstances that you didn't anticipate in internal testing. Better to have it fail for a limited number of users who signed up for that possibility than to have to do a Cyberpunk style recall.

Everyone on the planet can identify an alternate political group who would have them murdered if the situation gets dicey. The rich have been murdered by communists, the communists by fascists, the fascists by liberals, minorities by majorities, this religion by that, family against family, etc.
