I wouldn’t say so. In theory you’d expect a FAANG engineer to be able to construct a correctly terminating loop by reasoning about the loop invariant, but in practice every single candidate gets lost in guesswork and messing up the edge cases and termination condition.
I wonder if it's possible to take it a step further and make the pieces that connect the server to the internet (modem, the cable infrastructure, etc...) to run off the grid?

>Europe - itself very much in flux as you mention through the past thousand years - being "invaded" and America being "settled."

Sometimes, so-called invasions are really migrations. Its no longer correct to talk about aryan invasions, now its the indo-european migrations. On the other hand, the term invasion can be justified. The mongols were not migrants or settlers - they were invading conquerors true as history.
do you have an idea you could see yourself working on for 5-10 years? If so, quit your job and make the jump. You are going to be too burnt out from having a job and working your free hours towards building a start up on the side. Not having income will inherently drive you to work harder towards finding success quickly.

If you don't have any ideas, would recommend finding some ideas you are passionate about first while keeping your day job

Why does that article not address the most dominant cause of the wealth gap, which is broken homes and blacks dropping out of school, not going to college etc?

Hey, I work on Pulsar, will try and answer this :)

Topics (actually bundles of topics, called bundles) are what is assigned to Brokers. Topic assignment is dynamic, so when a new broker is added, the system will try and shed load from the busiest brokers to even it out on the system.

But unlike Kafka, when a topic is assigned to a broker, it doesn't have much state to move, mostly it just gets metadata added to it and opens a new "ledger" (which is just a chunk of the topics data over a time window, only one ledger is ever open at once). When it needs to serve data, it pulls that from bookkeeper nodes from previous ledgers, so the process of re-distributing load is pretty quick, it also doesn't eagerly pull in a cache.

Now, as far as the cache, that is primarily for "tailing reads", meaning, as writes occurs, and clients who are close to the tip of the recent data will just get it from the broker, without a need to pull it from bookkeeper. This is is one of the key parts about how Pulsar has multiple tiers of storage that help it have such good consistent latency.

Beyond processing writes, the biggest thing brokers do is handling "tailing reads" i.e., clients are consuming right near the tip of the topic. , this is the cache referred to. That means that when a new pbroker is three purposes:

1. Handling writes
Bing started 15+ years ago as a feature for feature clone of Google. Historically they've simply crawled Google results and replicated whatever Google returns. It could be a data point that Google has made the perfect search system as of 15 years ago - or just a footnote of the balmer era of Microsoft like Windows phone.
They told us that explicitly. We had been using the URL-based login on the app (i.e. open a browser with the URL and use the redirect to continue logging in), for almost two years. Then about a year ago, they e-mailed us just before a holiday and told us we had less than a week to move all of our apps to SDK otherwise they'd just disable us. Their argument was that "it's not providing the best possible experience to our users". There hadn't been a single complaint about it though.

We had nearly 100,000 users logged into our app via Facebook login so we were basically strongarmed into complying. We somehow pulled it off before the deadline for both Android and iOS but felt really dirty afterwards.
Above in the thread it has been noted that camera covers are not only about security. But also about preventing accidental exposure, e.g. when you accidentally click the wrong button in a meeting app, or if your app is misconfigured to start with the camera on, forget to close an app, etc. Camera covers helps prevent you from these potential embarrassments.
I like AAII, American Association of Individual Investors. It's a independent, non-profit organization with resources and publications to learn about investing without bias to any particular company or product.

I see they have on-demand webinars, too.
https://www.aaii.com/webinars

Local chapters have meetups with presentations and discussion. Now online, of course. There's a page on their website about local chapters and their activities. Presenters at chapter meetings are supposed to be educational and without a sales pitch. In practice they're 98% educational and may have a slide or a handout on the company they work for. Here's the YouTube page for past presentations from one chapter.

Ameritrade has videos on learning about investing, trading, and their platform features, including most basic "this is a stock, this is a bond" type videos.

If RBG had retired or passed away before the recent abortion case, Roe v Wade would almost certainly have been overturned fully or partially a few days ago. The court voted 5-4 to uphold and whatever hyperconservative federalist society nutjob Trump would have nominated to replace her would virtually have guaranteed the opposite result.

Abortion isn't the only relevant case that the court could overturn, we have decisions like Citizens United that have essentially gutted the political process for a generation and in the past few days the courts have handed massive wins to Churches and conservatives that allow them to discriminate freely. To pretend the courts don't have massive power to dictate daily life in the US seems to be denying obvious truths.

Is "None" the answer that would satisfy you? You seem to be implying a slippery slope, but you come off as saying "what's non-trivial shouldn't be attempted."

If you're actually interested in answering that very big question–which, I suspect, you might not be, only ornery and combative–you would do well to read what scholars have written on it. You might even Google the simplest component of the subject.

US government displaced and murdered native Americans for a long stretch of history. For multiple tribes this included extermination based on ethnic group. US soldiers acting in official capacity killed defenseless Native American civilians including young children based on their ethnicity. The genocide of Native Americans is well documented.
my laptop has a piece of tape over it, but i can still see the LED lit when it comes on. however, as far as the flash of a quick snap, does the camera on the MacBook take an image faster than the iDevices? the phones always take at least a second after pushing the button, so maybe Apple would be better off putting the same kind of camera in the laptop to ensure it is impossible to take a photo quickly
The flaw in the "Firing" argument is that the speech is a call to action, namely to fire someone. At that point, it becomes something like a threat, which is not protected speech. While the threat is not directly aimed at the individual, law does recognize that interference in the business relationship between two parties can be a wrong, for example https://en.wikipedia.org/wiki/Tortious_interference

That's a naive perspective of the role Slack plays in many organizations.

For example, much of the monitoring and alerting workflows in our company run through Slack. We use it more than email. We can rollback production deployments with Slack commands as well as interact with our staging environments - and that's just the tip of the iceberg for the workflows we've built out with Slack's APIs.
I don't think the intent was to draw a comparison between contemporary native americans and those of the 18th century. Instead, I think it serves to demonstrate that atrocious behavior is not exclusive to the european settlers.

The person who wrote the linked email is not part of the same organization (TDF) who controls the LibreOffice brand and is offering a free download. He's part of a company (Collabora) which provides commercial support for LibreOffice and contributes significantly to the codebase.

I'm sure your suggestion would help solve his problems. However, it's considerably more drastic than some of the things he's proposing, which mostly amount to marketing changes. Taking away a free download for casual users would likely be opposed by TDF.

I like the European farm subsidies, I think they are a great example of how to share wealth among a lot of citizens and maintain high quality food. Btw, 59 Billion seems like a large number but compared to the actual GDP of the EU thats a very very small number. Also in the US for example farm subsidies are pretty high and generally funnel to rich people, there is both farm related subsidies that go direct to farmers and insurance companies (among others) and then the farm bill which is another huge subsidy.

If my understanding is correct, type inference producing a set of possible types - instead of a single type - for each term has proven to be undecidable?

This is a shame, because sum types (e.g. Shape := Circle U Square U Triangle) are actually pretty useful, and languages such as Java ended up implementing them via class or interface inheritance. Languages often also required type coercion to deal with things like 0.2 + 5, otherwise + could have had a type signature like: float U int -> float U int -> float U int.

I don't know how you'd structure a society against hate. We can't seem to even come together over political ideas within cultures, where everything else is very similar, so I don't have a lot of hope for situations where the similarities are few and far between.

The claim was that single-frame grab attempts are prevented by an indicator that stays on for 3 seconds. First, you do have to be alert for all of these potential 3 seconds windows, and second, it doesn't prevent anything but only tell you that it has already happened.

It's pretty horrible. Apart from being hard to read (why pick an uppercase later that looks similar to numerals?), it only works for full dates or times or datetimes. You can't have literals for just years, or just hours, or just a a particular month. Even 10:20 is ambigious -- is that twenty past 10 (am), or 10 minutes 20 seconds past the hour, or a duration (iso also covers durations, but they are weird and clunky)?

I highly recommend ThoughtEmporium on YouTube btw.

As happens, each generation thinks that what they have developed will supersede what has happened in the past. This involves a failure to understand the lessons of the past. As far as database technologies are concerned, no one technological model will fill every area to the exclusion of all the others. Graph based databases are not an exception here. They are a rehash of network databases from the past. They have their uses, but it is not universal by any means.

What too many people have failed to understand is that SQL databases are not relational databases (though you can build a relational database on a SQL DBMS). There are certain problem domains for which different underlying DBMS's are a far better fit. It depends very much on what you are trying to achieve.

No one technology will "win" as there are always problems that are better solved using a different tool. There is an old saying that is oft forgotten and that is: If all you have is a hammer, everything looks like a nail.

We are supposed to have a large number of tools in our toolbox to solve the various problems that come before us. Let's be Master Craftsmen and use the whole range of tools available to us. This is applicable in the choice of database technology as it is in the choice of language or the choice of programming style or any other tool choice we may use.

> You can be a critic of implementations the system and yet still support the underlying mechanism

So the theory is great if only we ignore the practice? A protection racket works on solid mechanisms and even principles in theory. The implementation just needs the small detail of breaking the law. It also looks great from inside if you benefit even the least bit from it, but criminal from the outside.

> The US will basically spread democracy and capitalism.

Lots of countries became democratic and capitalistic because the US explosively "spread" them? What was the cost for those countries to still not achieve that? Protection rackets might have more satisfied customers.

> True capitalism is bad for the entrenched CCP

I'm not sure you understand what "true capitalism" means. Short version, it's not great for the regular person. There's no room for protections and you're only as valuable as your contribution to someone else's bottom line. Sounds familiar? Now I honestly wonder what happens if you apply "pure capitalism" to a country of 1.5 billion knowing that either the theory or the practice encourage lobbying (buying) for laws to favor the few, and selectively adjust the democratic process to eliminate the most inconvenient votes.

> But it is as close to perfect

In theory. But you'd have to be naive to believe that the US goes anywhere just to spread the good word, especially considering the current track record doing that and that since as you agreed they themselves are far from nailing the practice. Other countries have nailed both, take Scandinavian countries where people are treated equal, the GDP per capita is similar to the US's (+/- $10k), and the democratic process works in practice. Why isn't the US importing that rather than being concerned with exporting theirs?

Look, I don't know where you get your facts, your opinions, your education from but it's not the right place. The system failed you and hasn't prepared you for this conversation.
I suggest treat each chapter as its own book.

Then if you get through one chapter, consider that a success. Decide if you need the next chapter.
