I don't think CA is THAT much different in this regard. They can still claim ownership of inventions and IP for things done at home on your own time and equipment if it relates to the employer’s business or anticipated research or development (emphasis mine), which, for many large companies encompasses every project you could think of.

TTD uses code instrumentation so typically has a lot higher overhead than rr on single-threaded code. On the other hand, it can handle shared memory and use multicore, so for parallel programs on big machines TTD could be faster.

TTD has some debugging features rr+gdb doesn't have, like some cool query-based debugging features. But it doesn't let you run application functions (e.g. prettyprinters) at debug time like rr does. Pernosco consumes rr recordings and blows TTD away IMHO :-).

I am not convinced that culture cognitive differences are even half as strong as biological cognitive difference

There is no way that societies collectively decided by comitee to be patriarchal and hierarchical, rather it is a much simpler explanation that biology played a much more important role in making the world so patriarchal

To me, it's obvious there's an "appeal to authority/expertise-theatre" when there's a sense of emergency. That's one of the points of assigning authority.

But what the pandemic has showed is all the expertise in the world and all the authority in the world does not provide actual the necessary evidence to back decisions as quickly as the public alarm grows.

How many pandemic have been recorded in such detail that produces evidence relevant for current situations? How many lockdowns?

I mean: previous pandemics (1918 flu?) did not have to account for high speed means of transportations. Or extreme population densities. Maybe borders were more permeable in the past than they are today, but did people move as fast and in has large quantities as today?
a tech wins when the tech developers are enthusiastic about it. We have seen this before.
I wouldn't paint Trump's so-called presidency with the brush that makes it looked like he was a victim of lenses and biases. It's not our inherent problem he is objectively uneducated, unpresidential, racist, sexist, and just downright lazy. It shouldn't be surprising that his lack of leadership tainted nearly everything in the government, and that his few attempts at leadership actively hurt governmental policies and initiatives.
Reading that link, even back when it was written it feels like an article of first impressions with the bias of someone comfortable with many hours of use of a Unix shell.

1. Powershell isn't a complete greenfield and exists in a context, which explains many of the complaints.

2. any new tech use requires learning.

I could address each point but most galling was the conclusion:

"At this point we realise the truth — PowerShell is not designed to be an actual shell for users" Because wget did not output to a file by default?!? Really?!?

IMO, this article failed to hit the mark back in 2014 when it was written let alone now.

Edit: conciseness
Well, I doubt the ones I know that went to the us for vaccines consider themselves upper class. I guess it depends on how you define the term. The distribution of wealth is absolutely terrible here in Mexico. I'm a junior professor at a large public university, I have a wife and son and am our family's only source of income. According to the government's statistics my income of approximately 25K USD a year puts our family above the income of 90% percent of all families of 3. I guess that 90% figure might justify you calling me "upper class", but I think the lifestyle afforded to us by my university professor's salary is much more in line with what is considered "middle class" than what people think of as "upper class". From what I can see of my American colleagues, a junior university professor in the US has a pretty comparable lifestyle, and they don't consider themselves upper class either, I believe.

I won't do it, but I could certainly afford to fly with my wife and son to the US to get vaccinated (and, as many middle class Mexicans, all 3 of us already have American tourist visas). It would maybe cut into our savings a little more than I'd like, but we could do it.

I think the people I personally know that went to the US to get vaccinated are in a roughly similar boat to our family, maybe a little better off, but I don't think of them as upper class either.

You may also want to do sanity checks but, in those cases, I tend to deliberately abuse the inputs. Send a string, a byte string, some invalid UTF-8, an emoji, an invoice, and ensure that the thing can take more abuse than what the manual says.

What is missing from the title is that revenue is up. They are wringing more cash out of fewer players. This could be aggressive monetisation driving people away, either directly due to how it feels or indirectly due to dev resources pushed into fancy hats instead of core content.

The article does say that Shadowlands and WoW Classic carried the torch for revenue. One is old-Blizzard quality I guess, the other pretty much as expected for a new WoW expansion. People are going to buy it. Whether or not they stick around is another story. It does note that they did not confirm if subscription numbers are rising or not in WoW (modern).
+1 to this. Remote work vs work from home during pandemic times are very different experiences. The latter is definitely not pleasant in the long run. Even though I worked from home as a usual practice pre pandemic, breaking up the monotony with an occasional hot desking at some other place which may end with a board game night, or working a bit from a coffee shop, is the kind of thing that made remote work such a joy normally.
> Renewables + batteries will NEVER supply enough energy in a world that will require more electricity if it uses electric vehicles and move away from fossil fuels. The coal and gaz industry love renewables because you NEED gaz and coal if there's no wind or sun.

Let's see - the per capita total energy consumption - which includes transportation, industry, agriculture (everything) in the US is 80 MWh yearly[0]. The global population is expected to peak at 10 billion. Assuming the whole world consumes energy like a drunk sailor like the US does (and by the way, BEVs, for example, are twice as energy-efficient per mile than gasoline vehicles [1]) - that comes to 800 PWh.

The average solar cell produces 150 watts per square meter[2]. Running at 6 hours per day for a year, thus a square meter produces 0.3285 MWh. Therefore you need 2.4 million sq. km of land to supply the total global energy consumption (where the average consumption is 15 times higher than current consumption) only through solar. How much land is it? Quite a lot - twice that of India, and a quarter of the Sahara desert[3]. But remember this is spread all over the world. As a percentage of the total land area, it's not even a single percent. Agriculture itself consumes 60 times more area than this.

However, this is only from solar. The current state-of-the-art offshore turbines produce 15MW peak power already. Such a turbine has a rotor diameter of 236m. The optimal distance between turbines is 10D, where D is the rotor diameter [5]. Thus assuming a 50% capacity factor, an offshore wind farm produces 11.8 kWh per square meter per year. You would also need 12 million such turbines to supply the entire world's energy consumption per year. Assuming we get half of our annual energy consumption from offshore wind, you would need 33 million square kilometers covered in wind turbines. When it comes to areal efficiency wind, it is an order of magnitude worse than solar - however, the advantage is that the area is mostly free. Offshore turbines spaced kilometers apart can coexist easily with shipping lanes, while onshore turbines can and do exist without issues with ranches and farmland. By the way, the US coastline itself is 150,000km [6]. Thus, if you cover the coastline with turbines (only five deep), you can only generate the entire combined US energy demand from offshore wind.

And we have not touched on rooftop solar and onshore wind at all. So I fail to see how renewables will NEVER supply enough energy to the world.

Yep, that's why I prefer mypy/typeguard and type annotations for those sorts of things over checking in the body. It's frequently much, much easier to read, and self-documenting, since most IDEs have support for that when calling the function nowadays.

Similar argument made in this Times op-Ed in regards to tracking on the Times website:

“ Jean-Christophe Demarta, an advertising executive at The Times, recently told Digiday that even with G.D.P.R.-related changes, The Times’s “digital advertising business continues to grow nicely.” If people everywhere should have the same fundamental rights to privacy as Europeans, and if providing privacy is not unduly harming revenue, why shouldn’t The Times provide enhanced privacy to all its readers?

Readers everywhere could then be more confident that their interests in politics, health and other sensitive topics would not be subject to government surveillance or sold to the highest bidder. In the same way The Times leads in high-quality news coverage, it could also lead in respecting reader privacy.

I live in Portland and have a slide-in truck camper on my property. I use it for camping of course, but it is also part of my earthquake preparation plan. It is solar powered but also has a built-in propane generator. It is fully self-contained with all the comforts of home including fresh water storage, a galley with oven, stove, freezer and fridge. A bathroom plus a hot shower, comfortable bed, large pantry, closet, etc.

It sits on a 3500 diesel truck that can go just about anywhere.

I know this solution is not practical for everyone. But it is always fully fueled, fully stocked and offers considerable peace of mind. If you have been on the fence about buying an RV, think of it from this angle.

In some parts of Europe, digital attacks on proximity unlock systems are becoming a common way to break into cars. Especially for a system based on Bluetooth, it's difficult to defend against an amplification attack.

The key here is that one person can make a tool and sell it to many common criminals, and even if the auto manufacturer notices that they are doing this, there isn't an easy way to patch the issue. For something like a Tesla, it's difficult to imagine a software vulnerability that cannot be fixed with an OTA update, but for a manufacturer that doesn't have OTA update capabilities, I could definitely see cyber hacking tools being distributed and used in a similar way.

Thanks for the detailed reply. So it seems like your objection has nothing to do with the payment model, right? All of these are just generic engineering concerns with any product at all that has the ability to electronically enable or disable a safety feature.

Why are you concerned about and this particular product, as opposed to say cars, which affect orders of magnitude more people? Modern cars have many safety systems that can be digitally activated and deactivated, including the steering, brakes, throttle, and airbags, by design. The ECU alone in any vehicle, car or motorcycle, is hackable and could kill you (did in Toyota's case). All vehicles have LED lights to indicate safety critical problems. Nowadays, it's more commonly Android-driven LCD panels with many, many more failure points than an LED.

I mean, I hear you that electronic systems have many failure modes. But electronic control is more than routine today, it's utterly ubiquitous, so what's the cause for such extreme concern here that words like "psychopath" are justified?

Tesla alone is putting more electronically controllable cars on the road than all highway motorcycles combined in the US per year. Should we even talk about the failure modes possible with a Tesla or other self-driving car?

The University of Arkansas's hidden history of helping Nazis
This isn't that obvious.

Yes, if you bust ass all your life, have parents with professional middle-class values (regardless of actual income) and work in what is likely one of the easiest professions to develop wealth with in a period of time when a software engineer makes an abnormally high income in relationship to peers in other professions, sure, you'll do well.

But that's not really the issue.

The issue is that children of wealthy parents, for sure, study and make an effort to do well in school. But the required effort is just a _fraction_ of what a child of a wealthy parent needs to do.

A wealthy parent can pay for a tutor for a child who doesn't have much interest or curiosity in preparing of standardized tests, and the tutor will guide him/her to the extracurriculars that academics value. By contrast, a poor child with no tutors and no particular desire to do test prep, all other things being equal, just won't do.

What will happen to the child of your cleaner when she wants to attend the expensive vacation holidays of her peers, where undoubtedly a lot of socialization will go on where many will exit college with opportunities that she won't have, because she wasn't in the right place at the right time?

What about if she wants to pursue a career that isn't really profitable for many years? A wealthy teenager can take a gap year, switch careers, pay for a psychiatrist if they have some mental issue that for them will just be a simple obstacle, but for someone without the means can be career-ending.

No one is questioning _your_ ability to reach for success. Just understand that for wealthy people, a lot of your effort was just unnecessary, and they likely arrived at the same place you did with with less stress, better sleep, more parties, many more days off and a lot more opportunity to just take life easy.

Your wealth required you to pick the particular career path that enabled it, but other choices would have likely ended either in poverty or much less wealth. A wealthy child can pursue his or her dream opportunities with far fewer concerns on that front, knowing that they're covered.

My parents came from a much poorer background than me. They busted ass, taught me the same values, still work hard.

Frankly, I just don't work as hard, but I went to a great high school with _very_ wealthy peers who taught me the secrets of the upper classes, and I purposely chose this profession as a software engineer to my advantage, which has allowed me to take gap years, travel the world, and do a lot of things that a lot of my peers, who work much harder, longer hours, and more stressful positions in other industries will never get to do. That's not a declaration of my skills, but rather an assertion of the deep inequality and unfairness of the system.
