How many died?

The elapsed calendar time from the birth of the first human to when an electronic drink blender was first invented was much longer, but I wouldn't say that was more effort and sacrifice than getting to the moon.

Do you know how many lives were lost in Germany, prisoners marched in the cold by force, a huge number of them dying along the way, to dig underground missile production factories with their bare hands, being shot if they stopped? Or that those men leading those atrocious slave factories were then effectively saved from certain death from war crime tribunal, just to help with the early U.S. rocket program that went into the moon effort?[1][2]

That's not even including the sacrifices leading up to it by the U.S. and the U.S.S.R., which I'd include in the overall effort[3][4].

I'm all for healthcare, but, on topic, it'd make even more sense to find replacements one-at-a-time for all of the products we use daily that are made up in part by crude oil.

Most plastics, many foods, many skin products, etc. all come from some by-product of oil. Because of that dependence, big oil is not only a huge industry, it's most industries, most company, most products, and touches most consumers.

Also:

"There are 1.65 trillion barrels of proven oil reserves in the world as of 2016. The world has proven reserves equivalent to 46.6 times its annual consumption levels. This means it has about 47 years of oil left."[1]

Wars have been fought over it when we still had a lot left, and we've got until maybe 2068.

"You’ll track support for each party in each sector, moving wooden markers up and down the numerical tracks."

Unclear if this is discrete or indiscrete.

"Different sectors have different point spreads, reflecting their importance in the Victorian-era electorate."

Spread itself has discrete values, though maybe be representing something indiscrete.

"In this era, most British subjects didn’t have the right to vote, so the point spreads aren’t simply based on population distribution. They’re based on the number of voters..."

The indiscrete game world concept of unknown changing actual population, but a number of voters would be discrete.

"...and each sector’s overall impact on the election results, factoring in the value of campaign contributions, endorsements, and other means of influence."

Contributions value may be discrete, but endorsements and other means of influence I'm not sure about.

"As the game progresses, parties will reach maximum or minimum values in some sectors. These maximums and minimums affect the game’s strategy and evoke real-life political effects. No matter how strongly Scotland prefers one party over another, Scotland’s impact is limited by the number of voters in Scotland."

So, there are indiscrete things in game world represented, but it has a number of voters and that number itself would be discrete.

"The Conservative Party can also earn popularity points in the Workers sector, but can’t earn any red points there because Workers who support the Conservative Party prefer moderate MPs."

Seems like a calculable, discrete representation of the indiscrete.

Functionally it appears as a digital computer from the outside of the game, because of the point values.

But the point is that the game represents calculations happening in that game world with indiscrete variables like "variable support from unknown population", hence the "analog computer inside..." in the title.

> He said he transferred it to his personal Dropbox cloud account to use later on his personal computer.

Some companies don't draw the line between personal and work computers.

Most schools, colleges, and universities expect students now to supply their own computers.

But, while it's not surprising that someone today could consider that it might be ok just to take the data home like it's no big deal, I think Tesla isn't making a mistake in taking this to court, if it was clear in the contract(s) that the employee signed that such behavior was unacceptable.

You could jump to conclusions reading the title that the employee planned to sell the data or was working for a competitor, and you could be correct. But what's at issue, it seems, is that the employee didn't meet their contractual obligation.

I for one was glad to see it was about a board game instead of a short sci-fi story or an interview with the Prime Minister about their old pacemaker. Not that those wouldn't have been interesting, but I wasn't expecting a board game. What a surprise!

Open-source and free software licenses don't imply that the source must remain served on some site, and it doesn't imply that the license for the code cannot change for future versions of that code necessarily- as it depends on the license and/or other factors.

But if you have a copy of the license and the code and it permitted use of it perpetually, then it can continue to be used. That's my understanding.

> it’s not about me, but about ways to improve the code

This is true for me, but I also would admit that it's not all altruistic.

Specifically, I will report problems that may be rare for others and unlikely to be reproducible by the maintainer. I often provide information about the operating system, version, etc. in those cases to put a reasonable amount of effort into it, but I don't always expect it to be fixed by the maintainer.

However, if I determine later that the bug was caused by something else, I'll go find the bug I created and add a comment indicating that it was fixed or related to another problem, if it's simple.

Touting as 100 LOC using only stdlib:

* may show that Ruby can do a lot on its own.

* may show that a developer doesn't have to depend on another gem just to get the job done.

The Ruby stdlib is powerful, and depending on another gem could bite you if it were to become unmaintained at some point.

However, low LOC and use of stdlib isn't always the goal for development in-general.

I want to develop solutions quickly that work well and are easy to maintain. If it's easy to learn also, even better.

In terms of the size of the code, even in text form, there's a lot I could do. I could reduce lines by replacing EOL with semicolon. I could remove unnecessary spaces. I could use shortest variable names. I could store a compressed version of the code in the file and then do eval of the decompressed version. Those don't make it a better solution, unless the goal is to obfuscate and/or minify it.

I know that's not the point, though, and I'm mentioning it only so that people will think about LOC as what it is- just a metric.

Without even any AI or ML:

* Average counts of emojis, messages, acronyms, etc. could be misused by a human reader to determine things like age, religion, or ethnicity. If we frequently use poop emojis, we could be considered immature. If we frequently use anger emojis, we could be considered hot-tempered. If we frequently use sad emojis we could be considered to have depression.

* Counts of specific words or phrases in each language could be misused to convey physical and mental health problems that may be affecting an individual.

* The median length of a user's messages not including URLs, things in quotes, or tick blocks could be used to assess whether the user tends to be concise or wordy.

That data could be sold and could make you unemployable because their statistics indicate that you're overly angry, when the anger emoji was just your shtick at your last job.

Even if you're using the data just to see when people are working, if you have a team of employees that are productive but don't communicate much, that data could be misused. If their manager doesn't get along with the team and wants to move to a different one, when a higher level manager is cutting headcount, the team manager could say that the team has always been lazy and never listens to them, so the higher level manager fires the manager and his entire team, based on data provided by the analysis of the IMs and the manager's account. Since the data isn't a true indicator, it shouldn't even be used as supporting evidence of lack of work.

> It doesn’t say that the global administrator does not have access to the message content.

Slack also allows administrators to view deleted content, etc.

Slack used to let users see who those admins were in certain places; if that's still true, then finding out who those people are may give insight into who has the ultimate form of political power.

> I have never needed an SD card

I need to use SD cards for my camera and RPis. That's a significant amount of users that would buy Macs, even if you don't use them.

> and have gone all-in on USB-C

The move to Thunderbolt 3 / USB-C seemed to be hinged on the assumption that all new products would be USB-C. The prior removal of the headphone jack[1] and replacement of the lightning-adapter airbuds included with new iPhones set precedent to allow them to continue to simplify. But there's a big difference between (a) providing a replacement that effectively works the same way and (b) having a market based on being best and svelte, but expecting that the average customer can and will buy replacement lanky adapters and big ugly hubs that get in the way (especially when the cheaper ones can cause more interference[2]).

Apple once had a "Think Different" campaign, and perhaps that transmogrified to "Be the Change" in the 2010s. "Think Different" was about producing the best product, with a quality product that worked better, not about forcing customers to take on the burden of a mess, making their lives more difficult and looking out-of-control. "Be the Change" is activism which often causes problems for some, with a goal of things becoming better. "Think Different" works better in product design and development. "Be the Change" is for Human Resources and Marketing.

> Please just do MagSage + USB-C, so I can maintain my one-cable-for-everything, making traveling lighter and simpler. Here's my counter argument to all those that love MagSafe: makes traveling a huge hassle, forcing me to carry a special charge brick that only works for ONE device. In 2021 going forward, I will flat refuse to spend money on anything that doesn't use USB-C or Qi charging

It's expected to have Thunderbolt 3 (in form of USB-C) on it. I'd assume that they will allow charging the computer from it, as that's part of the spec of Thunderbolt 3; I'm not 100% on that, but as keeping that capability would be part of the Thunderbolt 3 spec which includes Thunderbolt, USB, DisplayPort, and 100W power input[3]. It just wouldn't charge as quickly.

This MagSafe will probably be the Qi-supporting MagSafe[3][4] which can be 15W for faster charging or 7.5W for Qi and will probably support the ring chargers, probably under the touchpad, given design choices from existing charging stands[5].

> I can now travel with a single 2xUSB-C power brick

And you would probably be able to do that, but it will charge faster with MagSafe.

> I am all for removing the TouchBar

Yep. I couldn't easily change brightness or volume when in context specific mode with the settings I had by default, and it was distracting.

It can be emulated[6].

How would you approach setting up and maintaining the following nano-aquascape, with an outcome similar to the Walstad method[1][2]:

* freshwater 11.3L natural tank, ranging 9.5L - 11L through evaporation

* no powered filtration, aeration, and optimally without a water heater

* little if any sunlight

* water temperature in tank may range 18.3C to 24.9C through each year

* 1 or more aquatic creatures, preferably one creature living a few or more years, removed within a day if they die and replaced within 3 weeks

* no water changes after 2-3 months of stabilization initially

* no more than a few hours of initial setup

* little maintenance required to sustain itself as described other than topping tank with inexpensive bottled spring water

* high probability of sustaining itself within these constraints for many years

I read and experienced that smaller tanks are harder to setup with 10cm of sand possibly needed for Walstad method that size tank[3].

In "Ecology of the Planted Aquarium" and on her site, Walstad writes that she had success with 3.8L and 7.6L tanks using her Dry Start Method[4] to setup the plants, and then hosted shrimp. However, as interesting a shrimp are, my experience with ghost shrimp was that they were inexpensive, looked lively, and then died suddenly within weeks. She speaks of red cherry shrimp, which I've not found locally. I recommend her site[5] which has a lot of information about Planted Aquariums along with the latest corrections for her book; she also describes how she bred guppies in 12 gallon plastic tubs without any filtration or aeration[6] outdoors 15.5C-25.5°F.

Ok- so... when I don't wash the aquafaba off of the beans in cooking, I get- let's say- "bloated".

I can only imagine eating these could result in a rough approximation of the decibel level of the Dragon taking off from Launch Pad 39A.

While Apple isn't right on everything, they are a business, and they have the responsibility to decide what they will provide and what they won't.

If they can't change X because it will screw over critical application group Y, then developers can complain as much as they want until they have some practical way to deal with that. If they were constantly screwing over Y, where Y was different depending on the problem, they could eventually screw up all of the apps, users, and developers.

> Free users don't care if you tell them to fuck off.

You don't have to and shouldn't respond in any specific time period. Even if you're the sole maintainer of a critical project and you imagine the world wants your head, the world has to wait sometimes.

However, users may abandon projects where support tickets go untended, maybe even writing a post about it in the process[1], so try to respond when you can, unless you've abandoned the project.

As a representative for a FOSS project or even a bystander commenting on a PR, respond professionally and succinctly.

If you shouldn't accept a PR, don't.

If it's a request that seems hostile to the project, and you have time, either leave it for a little while to cool off, try to serve it with professionalism without getting off-topic, or at worst close it.

If needed, add a "code of conduct"[2] so that you can "encourage a pleasant and productive environment by responding to disruptive behavior in a fast, fair way"[3]. Note that instituting one before it's needed, while seeming proactive, may put off some users.

If you screw-up, apologize briefly, then fix it or move on.
