Completely agree and this has been my experience ae well. To this I'll also add, inadequate thought put into data modelling. One would have to think lesser about query performance or cost of overfetching if data is modelled around the needs of the system it would serve instead of just modelling real life entries and their relationships as is, straight onto the database.

I'm just not sure you're applying the right kind of reasoning here. The question is, what do we learn from this event?

As a Canadian power systems engineer who lives and breathes NERC compliance standards every day (something I'd never ever thought I'd see discussed by the broader public) I find it bizarre that everyone is staking out their position on this based on political allegiances rather than focusing on analyzing the event.

There are also extremely broad misconceptions that Texas is somehow exempt from all federal regulation that are fueling people's motivated reasoning on this topic. NERC reliability standards are enforceable in Texas! [1] All existing and future NERC winterization rules apply just as much in Texas as anywhere else.

Yes, ERCOT messed up. Yes, there are big issues to be resolved here. Some of those issues are national in scope and some are Texas specific. But drawing a direct line from Texas being its own interconnection to this failure simply doesn't follow the facts for me.

Zero reserve rate does not mean no practical limitation on money creation.

Banks can 'create money' on accounts of their clients (as these accounts represent just obligations of the bank to their clients). But once created, if clients want to use these money outside of the bank (say to pay for a service to someone who has account in another bank), then bank must move equal amount of 'base money' to another bank (or to give cash).

If a bank have balanced inflows and outflows of base money, then it can 'create money' in the same pace as other banks in order to stay balanced (if it 'creates money' faster than other banks, then outflows would rise faster than inflows, and the bank has to sell some assets to compenstate).
Assigning Blame for the Blackouts in Texas
Indiana study, excluding elderly in nursing homes says death rate following infection is 0.26%.

https://www.ncbi.nlm.nih.gov/pmc/articles/PMC7505013/

Assume that COVID deaths are accurately reported. Assume 500K dead in the USA already. Then 500K / 0.26% = 192 million already infected and mostly recovered.

With 328 million Americans, 192M / 328M = 58% infected already which is well on the way to herd immunity at suppose 75%.

Its not just the USA, reported cases are dropping in a similar way elsewhere in the Northern Hemisphere.

This is been discussed before when Apple and others have changed the emoji glyphs of existing Unicode code points. This should be highly frowned upon as it, in effect, goes back in time and alters the historical written word (or picture in this case). It would be like opening up all copies of Huckleberry Finn on the planet and replacing certain objectionable words with others. This should not be OK. If Apple wishes to allow its users to denote a Covid injection, they should add a new code point to represent that.

Expect them to? No. Wish for it? Yeah, definitely. And then hold them accountable for the decades of gaslighting while they knew that was the case. That’s kind of the role of a government. How is GameStop stock more controversial than climate change denial? GameStop is ephemeral, climate change is existential.

The easy thing is to say “bankrupt the fuckers, kill the orgs!” and I feel that. I want to see them suffer for the path they’ve put the whole planet on. The responsible societal thing to do though is probably to mandate renewables, stop petro subsidies, and make them eat the cost for the switch if they (the orgs) want to stay alive. We have the evidence; it’s public knowledge now even if not widely disseminated.

They’re adding renewables, but not fast enough because there is still profit to be made in petro even though it fucks us further. That has to stop ASAP. Governments are the place where that happens.

Indeed, but there are other important factors besides size.

DSN have way bigger requirements in terms of signal to noise ratios, since they need to demodulate received signals.

Scott Tilley, on the other hand, seems to be mainly interested on detecting the presence of signals, not necessarily extracting information from it. Then, he could build a bigger dish, but he doesn't actually need one to achieve his goal.

I notice that another guy commented here about that. His comment is dead now, but he had a point. I found it informative indeed, I've always asked myself why spacecrafts "wasted" energy with carriers and never realized they make the signal easer to find.

> One type of lethargic entrenched entity survives on the basis of consensual interactions

So goes your theory, but not in actual practice. For the qualities under discussion, generation companies have seemingly acted in lockstep, therefore it makes sense to view them as a singular entity. And it's not productive to call signing up for electric service consensual in any meaningful way. The ability to technically opt out isn't worth much when it would significantly impact your life, as evidenced by the vanishingly small amount of people who do so.

You can also come at the reduction from the other direction and define how interacting with the "government" is technically consensual as well. eg don't pay taxes, do the work required to not have your income flows surveilled, etc. Or in this case, don't sign up for the (de jure) government power grid, and go your own way. Which is equivalent to what you would have had to do in the first scenario anyway - both scenarios end up with people who devoted their lives to being independent from the electrical grid being fine, and those who didn't freezing.

The point is that all frameworks ultimately have their limits - they are only good when their reasoning power holds. True understanding requires being able to switch between them as appropriate, rather than shoehorning everything into one and insisting that it must fit.
Perseverance's Terrain Relative Navigation uses a camera system and generates a full 3D position fix, but the idea is similar.
In addition to this, there are all the horror stories of re-writes being a waste of resources. I've done it myself, and wish I hadn't.

Having said that, I think this is one of the great benefits of micro-service architecture. You can re-write piece by piece as you add functionality or create a measure of improvement. But don't use the "we need to write this as micro-services" as an argument.

You say "re-write large parts", so I assume that means not the whole thing, and not a new language. If that is the case, I'd suggest tackling the "re-write" as a piece by piece upgrade rather than a re-write, and look for a business case for each component you plan on re-writing.

The engineer wants a beautiful system, the business wants a system that works. The business pays the engineer. So buy "selling" the business the benefits of specific improved functionality, you may get a new beautiful system.

Is there a part of the system that is particularly expensive part of the app from a services (DB, API requests, etc) stand-point? Can you quantify for the business the benefit they'd get from re-writing that part
of the app, and the cost savings they'd expect to get?

If you're close with the design team (which I hope you are, or suggest you become), are there business goals they are designing for which would allow you to sandbox a part of the app to be re-written? Do that 20 times, and you've got a new app, and you didn't do a 're-write', you just kept adding great functionality and cleaning up as you went.

So, I'd suggest getting the idea of a 're-write' out of your head, and instead approach it from a "how can we improve this tiny piece of the app while pushing the business forward".
Early starships got me thinking: given the high likelihood of a failed starship landing, and maybe having the ability to send one before fully engineering a payload…

What would you ballast a starship with for the practice missions?

Useful materials which might survive a RUD and aim for someplace near a likely landing zone? If you crash the parts of a milling machine, a lathe, some tooling, some assorted metals stock, and a bunch of assorted wire, well sure you just cleared out a machine shop auction, but maybe there comes a day when an early Mars colony would be thrilled to go clean up your “landing” site.

When making changes to a block of code or block of text, I frequently just comment out the code and rewrite it anew. I might copy-paste existing code (just to avoid stupid transcription errors). If its too large to see both what I'm writing, and the old code, at the same time, I just use two windows on the same file.

This is relevant to writing fiction or non-fiction as well.

> Eugenics, the only discredited science, that seems to work exceptionally well when applied to plants, livestock, microbiology, horses, household pets, but magically fails when the idea is applied to the human race?

The failure is a result of the lack of a definition for “good genes” aside from whatever any random person thinks is good. That is, the fitness of an organism always and necessarily refers to a specific environment, and the characteristics (genes) that make it fit for that environment are not the same as the ones that make it fit for another environment. This means that there is no objective measure upon which to determine which genes are good and which are not. Eugenics is subjective.

> The idea is morally reprehensible, but the idea that all you have to do to cull out say "sickle cell disease" from the human race as a whole is to stop say "black people" from breeding is actually scientifically sound.

In the first place, sickle cell anemia provides some protection against malaria. So whether it is adaptive or maladaptive depends on the environment. But secondly, sickle cell evolved naturally, and removing it from the breeding population doesn’t stop that from happening again.

> Like I said the idea is morally reprehensible and we should never do that. But the idea that you couldn't theoretically control a population and eliminate "undesirable" traits from the gene pool is just willfully ignoring the obvious soundness of the mathematics.

I don’t think people are denying what you’re claiming here. They are responding by noting that there is an incredible power differential between the eugenicist and the people who are prevented from reproducing (I’m sure this is obvious) and there is no objective basis on which to scientifically decide who is supposed to reproduce and who is not. Together these facts create the inescapable impression that eugenics is about having kids and preventing the competition from doing the same.

If you're not paying attention it would look that way, yes.

If you pay attention you'll notice that just.js is using postgres as their DB, while all of the node benchmarks are handicapped by either using mongoose/mongodb or MySQL.

There is no node benchmark with postgres, but all of the fastest benchmarks used it.

"lithium" is a good example to show how much of an impact switching to postgres has. All of the 4 lithium benchmarks are identical except in what DB they use.

The results are: lithium-postgres-batch (#2 - 659850), lithium-postgres-beta (#13 - 398773), lithium-postgres (#14 - 398258), lithium (#45 - 271989). The last result is MySQL.

Not totally but more then other posters on HN that were making claims without research. The NERC report will be totally reliable but that will take 6+ months. And if my conclusions are wrong, they're wrong and I'll update my blog.

I made this post as a direct response to previous HN and Reddit posts where the layman were forming conclusions. I did not see a single person quoting or referencing a single standard to back up their claims. I went out looking for something to back up claims and this is what I found. I formed conclusions off this and included them.

It's depressing to me that the reason we don't have decent automation systems in place is that humans are still much cheaper than kiosks. It's an insult to our species IMO that humans are still used for tasks that could be done by relatively simple machines.

I heard a story once about how construction sites in India don't often use tools like bulldozers, because it's so much cheaper to just hire 400 dudes with shovels. I'm sure we'll all look back at retail and the food industry in 20 years and view it as barbaric that humans were used to do such menial labor.
