Great reply.

Counterpoint though: that automation in and of itself is more failure area.

I can imagine a similar story where the deployment pipeline incorrectly rolled back due to some change in metric format and caused the infinite loss, for example.

The thing with these being a 1 in a million chance is that there's thousands of different hypothetical causes. The more parts the harder to predict an interaction and we've all been blindsided by something.

I would personally hate the stress of working on such high stakes releases.
That’s the main thing I feel - individual core speed is almost always the determining factor for “teh snappy” on modern desktop/single user systems.
When code is written to interfaces those interfaces can be mocked without mocking frameworks. Mocking frameworks mask poorly structured code.
I still run. But I walk too. And I now don't feel like I'm messing up any sort of pace metric when my run becomes a walk or a phone call or I drop and do 30 pushups every kilometer, etc.

It led to a large increase of daily activity.

It's like how I became a home cook when I bought my first bluetooth headphones. Suddenly I could comfortably listen to Youtube debates and podcasts and audiobooks, needed something to do with my hands while listening to them, and ended up learning to enjoy spending time in the kitchen.

Allow me to even more strongly disagree. I've not yet seen a situation where strongly-tested private code would have helped, although I routinely come across cases where too many tests get directly in the way of a refactor or bugfix that _would_ improve the program.

These days, I'm of the opinion that you should test at the highest level possible (if testing a web service, for example, at the level of the actual public API to the service), thoroughly define the behaviours expected for those APIs, and leave the insides of the service entirely untested, unless you have _very_ good reason to. (Critical code, payment code, hard-to-test code, etc.) This ensures you have the important behaviours tested, but leaves you free to modify implementation details as necessary without needing to alter or rewrite entire swathes of test code that suddenly starts failing because you decided to break up or consolidate an inner method.
True although maybe doing the top N problems for the company is a shortcut there. No point in spending a lot of time on a type of problem they will never ask.

This article is really stretching when the conclusion is smacking him in the face: "Use quadratic Beziers."

The original article points out that quadratic Beziers have most of the desirable properties with very few of the downsides.

It used to be that the issue was that you would have to use significantly more quadratic Beziers to approximate something that a much smaller number of cubic Bezier's could do. This was a big deal when a font file might clog up a floppy disk.

Now that we're slinging around gigabyte patch files. Do we really care?
It's interesting to me how visceral of a reaction the ideas that underpin this article create in so many different individuals' comments I've read in threads like this, despite economics and monetary policy typically being so boring.

One of the fascinating threads to pull within it is the origin of debt and credit creation. It raises some fun questions (some of which are just more random offshoots related to my interests than monetary policy or economic theory):

1) Did all private wealth held in USD originate as monetized federal debt at one point?

2) If banking systems didn't have access to fraction reserve systems, would they be effective tools for debt/wealth creation?

3) Is debt creation the same was wealth creation? How can labor and commodities even be effectively monetized without fluid systems of debt creation?

4) If the lowly game of poker was once used as way to build ad-hoc credit and wealth, before more sophisticated financial systems were more commonplace, how rigidly should we look at debt creation at all, federal or otherwise? Perhaps more gamified and ad-hoc systems would create a higher baseline of wealth globally? [1]

So many interesting questions.

One of the interesting things for me about the hypothesis is that if humans had developed better food preservation techniques this outcome might have been different. Specifically a lot of large animals would rot before one could finish eating them so the rate of consumption was higher than strictly necessary. (not that early humans cared, but later humans developed a wide range of preservation methods due to scarcity pressures it seems).
I can look at the wet-bulb temperature and see exactly how far trees will get me. This time of year, it isn't far -- which checks out, because I have plenty of trees and they don't stop the heat. Swamp coolers (trees are swamp coolers, thermodynamically speaking) are brilliant if humidity is low and freshwater is plentiful, but if either of those wheels come off no amount of wishful thinking will make evaporation work comparably to a refrigeration cycle. Where I live, it's the humidity. Fortunately, I do have real AC, and even better, my power mix is predominantly nuclear so I can crank that AC and get real cooling without pumping legions of dead dinosaurs into the sky. Damn it's nice to live in the 21st century. Or the 20th.

Also the RISC-V ABI requires that the initial code passes a pointer to a minimal device tree to OpenSBI - this means it can tell it where the UART is, how many CPUs to expect, where the interrupt controllers are (and what type they are) etc etc - this can then be passed on to uboot/uefi/linux or overridden or edited as they like

A lot of the time _private_ methods on one class end up making more sense as public methods on a helper class of some kind (or public methods on other classes).

One issue that leads to private methods in Java is the lack of any way to extend the set of operations on built-in classes: a problem that Kotlin and C# solve with extension methods.
Solar and EV Booms Push China Toward Energy Tipping Point
This.

When I did C++ programming, I would test via public interfaces. If it didn't seem sufficient, or got messy, the reason would always be "This is a big class that is doing a lot of stuff." I would then identify all the things the class was doing, make classes for each one, and have instances of them in the original class as private members.

This way I could test the individual classes easily, and still test the (formerly) big class using only the public interface (with appropriate mocking as needed).

The main thing I learned from unit testing is to pay little attention to the word unit. Insisting on testing the private methods after the exercise above is usually a symptom of aiming for a level of intellectual purity that does not benefit the code.

(Of course, a better solution may be not to use OO to begin with, but that's a whole other discussion).

It won't solve the problem, and that is a ton of mentally ill people with barely to no access to adequate treatment. Locking them up in jails may help for a few days or weeks but is horribly expensive to taxpayers while still not solving the problem (or make it even worse, given how conditions behind bars tend to be).
Those very smart developers would be just as effective in a mainstream language, and probably more so in an appropriately chosen mix of languages. It seems like the real advantage of lisp is that it self-selects for smart people who program for fun, and these people typically are also good developers.
I don't exactly understand what this has to do with continuous delivery, but maybe I just don't know enough about this topic.

I personally believe it's somewhat possible that there was some CIA involvement in JFK's assassination. I did not watch the entire video, but the part that addresses potential CIA involvement seems to have 2 main flaws IMO:

1. It only addresses the Vietnam War as a potential motive and "debunks" this motive. Geopolitics is complicated, and there are countless other potential motives, especially surrounding Cuba and the CIA's involvement there (Bay of Pigs, etc). The parts of the video I watched (including part 2) did not seem to address this at all. Eliminating one motive does not by any means eliminate the possibility of CIA involvement.

2. The video's creator seems to assume that CIA's involvement would consist of "hiring" Oswald to perform the assassination and that Oswald would have full awareness of the plans, etc. This is not the only scheme in which a conspiracy may have taken place, and in fact seems like a highly unlikely and unsophisticated scheme. It seems much more likely that Oswald was "used" rather than "hired" and that he was either convinced or coerced to shoot Kennedy. This is how murderous intelligence organizations do their dirty work (the CIA is known to have killed people) - via coercion, power, politics, propaganda, and not via direct orders or contracts. Assuming my theory is correct (of which I do not have certainty), Oswald likely had his own motives to wanting to shoot Kennedy, but it required a conspiracy to actually get him to carry through with it. This model of the relationships and dynamics involved seems entirely foreign to the video's creator and is completely unaddressed.

In general, discourse around the JFK assassination and potential conspiracies focuses way too much on the shooting itself - ballistic physics, positions of possible shooters, analysis of film. This is a complete distraction from the more important question which is around Lee Harvey Oswald's incredibly suspicious relationships and contacts with known CIA people.

Other studies show that outdoor walking relieves stress(1) and provides an opportunity to think about problems differently (or perhaps "creatively")(2), in those 40 minutes a day would be more than sufficient to experience advantages.

However how those 40 minutes take place would affect the result. Merely counting 40 minutes of doing chores is not the same as an extra 40 minutes added deliberately to a person's day. Similarly 40 minutes on a treadmill is unlikely to feel as relaxing as a walk through nature. Drawing detailed conclusions from activity studies is problematic, but the broad conclusions are consistent: the body likes movement and lots of it.

> Economies of scale aren't a goal on their own. Scaling something up will always have side effects... in the case of too dense urban areas, it's for example the sheer amount of traffic. For example, a quarter full of high-rises, no way you can get away without expensive high-capacity subterranian trains to handle commuters, and surface traffic is going to be a hot mess even with just shuttling the basic supplies for supermarkets, restaurants and the likes in one direction and waste on the other direction. In contrast, even a standard European mid-sized city can get away with cheap bus and tram lines.

But that high-capacity transit more than pays for itself (just the land value increase alone is more than the cost of building it). Yes there are costs to building densely (obviously to build a skyscraper at all costs more per square metre of floor space than building on the flat), but the end result is that more people can live (and more productively) for less total cost.

> Another effect of urban over-density that's often neglected is human health, both physical (we've seen that with COVID, just how fast pathogens can spread in urban areas) and mental. I mean, even here in Munich or Berlin we're not at the US levels of mental health and housing issues with people defecating on the sidewalk, but still it's noticeable how cities tend to have more anti-social behavior, as poverty and boredom are definitely contagious especially when not backed by the implicit social control that life even in smaller cities brings.

Do you have any evidence for that? The last results I've seen are that suburban living is significantly worse for mental health than dense urban cores (and I wouldn't be surprised if that was true for physical health as well), and frankly that fits with my experiences.
Yes. If the PC support folks don't need the manual, just send it along with the monitor to the end user. Why did they need to throw the manuals away so fast?
I don't know exactly how many degrees the shade will bring the temperature down, but just today my portable temperature sensor reported an 8F degree difference compared to one in the shade - both were in the same area of the house, but one happened to be where sunlight was coming in from a narrow window. And the sensor was in the sunlight for under an hour when I recorded the difference.

Of course, this is spot heating, and over a whole house the effect will be diminished, but it tells you how quickly things can get hot.

After an ios update where my phone started tracking a move ring (I was lazy and accepted some new defaults) I was definitely more motivated to close it every day.

I’m American but I’m typing this comment out at a campsite in Iceland.

I noticed they pointed out how many public bathrooms Iceland has. This seems misleading to me. From my understanding, in Iceland it is literally illegal to just pull off the side of the road and pee if you need, since nearly all areas of the country have laws to protect the nature. (For example it is also illegal to hike or camp off-trail.)

This is only tenable if there are a large amount of public bathrooms available, otherwise tourists would just ignore the law. So Iceland has a disproportionate amount of bathrooms for conservation reasons.

It is even more misleading because many of these bathrooms driving around cost a small fee (200ISK) to use even though they are “public”, I.e. owned by the government and available to everyone. And they only take credit card.

In Reykjavík finding a bathroom is probably about as hard as finding one in NYC.
> Selling options is also like that.

There are plenty of bad options traders, particularly retail...but this is an oversimplification. You can buy an index fund, and it can go to zero (however unlikely). You're not guaranteed any return, whereas at least selling an option has some guaranteed fixed premium.

Professional options traders are incredibly sophisticated, and most of the tail risk is offloaded to people who are always long biased. Options as a whole massively improve price discovery in markets.
