> Does anyone have any quick checklist or metrics to make decisions like this? When does it make sense to evolve from a vanilla RDB to a timeseries one?

10 daily metrics for 350 entities result in `10 * 350=3.5K` reading per day. This translates to `3.5K * 365=1.3M` readings per year. Such workload can be easily handled by any DBMS out there. There is no need to search for specialized time series database for this workload.

The need in specialized TSDB solutions arises when ingestion rate reaches a million of readings per second and the number of readings stored in the database exceeds hundreds of billions and trillions. Such a workload cannot be handled by general-purpose database, but it is easily handled by specialized databases such as VictoriaMetrics. Fun fact that it easily handles 10 trillions (e.g. 10K billions) of readings in a single-node setup - see https://victoriametrics.github.io/CaseStudies.html#wixcom
Take a look at https://skyandtelescope.org/wp-content/uploads/3-scopes.pdf for a good overview of 3 typical entry level suggestions. I have the Onesky (or rather it’s European sibling the Heritage 130P) and enjoy it. It doesn’t have any fancy features, but is easy to move around, doesn’t take up much storage space and still has plenty of power!

If you’re willing to spend some more, the Celestron NexStar 5 and 6 are solid telescopes that can automatically move to specific objects in the sky (this is called GoTo) which is really nice if you want to focus more on viewing objects rather than finding them. They’re low on maintenance too and work well for showing others objects in the sky as they can keep whatever you look at centered in the eyepiece.

I wish a lot of the React conversation would focus in on WHY it is so popular even for apps it shouldn't be.

In my mind the mental model shift towards completely modular components including their CSS(in JS), behavior and Dom/html(jsx) is just a very pleasant front end development model.

Its hard to go back to the old ways once you have experienced the productivity of React. I say this while obviously acknowledging dealing with the tooling ecosystem can be frustrating at times.

This sounds pretty condescending to me. I've worked on C++ for a long time, including on bare metal and compilers, and yes, the abstractions are totally comprehensible. But keeping them in your headspace is a full time job. The sheer size of the standard belies "simple" tool.
What you're really suggesting is that moderated forums with more than 100k users and controlled by a single entity should be de facto prohibited. But then it really has very little to do with Section 230 and you might as well just call it what it is -- antitrust.
Epidemiologists are the experts, I'm baffled why so many people are asking physicians about coronavirus.

Physicians are not scientists, they aren't supposed to make policy decisions.

It goes to show how few people understand what Science is and probably more dangerously that Medical is mistakenly thought as Science. (Medical is older than the scientific revolution,it's a hybrid of Tradition/Authority/Art/Science)
I have a side-business in digital signage. Professional displays are indeed usually dumb TVs and are made to witstand 24/7 operation and may have higher lumen, etc. They do come at 4k. They also usually come with better management software and more ports. They can be connected to the internet for some remote management but I’ve never used that.

There’s of course a price difference between you $300 cheapo consumer stuff, and a $1000-2000 pro display.

I used to have these pro displays at home with Chromecast, works fine.

It's not 1989 anymore, we have proper cryptosystems now. I don't have a worked example but elsewhere in the thread someone, it sounded like a dev, mentioned it's being worked on. You can encrypt for certain public keys and then only those people can decrypt the contents.
I've always found it funny how we treat companies like Google as imaginary people with no single individual bearing responsibility.

To be fair, some people are aware of the people involved like Jeff Dean, but I look forward to a shift in the future where individuals within companies are as popular and held to the same standards as individuals within politics. Some of these corporate individuals already seem to have just as much power so hopefully it doesn't stand to be too much of a stretch in an ideological vision for the future.

With respect to this particular case of Timnit Gebru, it sounds like she was already on her way to being let go. From reading her Twitter, it seems like she has a flair for the dramatic which could make her critiques of people potentially come off as needlessly harsh and unconstructive. Whether that's good grounds to fire her may only be known to those within the company who interacted with her most I guess.

> It has tilted many democracies towards right-wing populism and fascism.

Surely the obvious counterargument to this is that a fully centralized web tilts democracies towards left-wing communism and censorship-enabled dystopias.

Right now a small group of left-wing zealots at Facebook/Twitter/Google can erase a person from the web. Is that good?

Do technologists want to enable this?

Mass bans are happening right now on twitter, often with no reason given and terms of service that allow a privileged few to exercise unlimited and arbitrary censorship.

The very fact that people who are politically on the left are calling for an end to decentralized tech is evidence that their side has a systematic advantage at the most powerful censorship agents in the centralized web. This post, and others like it, is an admission and a justification for why decentralization is necessary. If such posts instead merely talked about apolitical crimes like child abuse or scams, then I think the justification for decentralization would be much weaker.

I doubt that (at this stage) TVs have something similar builtin. When they come with Alexa/GHome/... it’s usually the software and not an actual Alexa device built in.

I'm entirely incapable of understanding how a UK SLC "loan" can be considered a loan in the conventional sense of the word when it seems to have literally no characteristics of a loan, and every characteristic of a tax:

* You only pay it when you are in employment and earning money (with a minimum salary for repayments to be taken);

* The repayments are calculated as a function of your taxable income;

* The balance isn't discharged by bankruptcy;

* The balance isn't considered by lenders when assessing your suitability to take on "real" debt.

As far as I can tell, it's a graduate tax (on those who took a loan) for all intents and purposes.

I see comments from students talking about being "crushed by debt" as a result of taking an SLC loan, and I just can't work out where this perception comes from: yes, it decreases your take-home pay, but since there's a minimum salary threshold for payments to be taken, it's never going to leave you destitute.
You're saying they make $15k a year after or before taxes? Or that is their yearly expenses?

Right. But they have welfare programs to fall back on. Every homeless person on the streets of SF is cut a welfare check by the govt courtesy of the tax payers. There is no such thing in India.

Perhaps the problem is that there IS a govt welfare program. The complaint currently is that what’s being done is not enough. The truth is that it will never be enough. The govt and tax payers can shovel mountains of dollars into the maw of the problem and it will never be enough.

The way American welfare programs are designed is like sticking a band aid for cancer and hoping rosy health will return.

If we stop relying on govt, perhaps our tribal instincts to care for each other will return ...perhaps it will finally dawn on us that we rely on our kith and kin...that we come from other people like us and it was not the govt that birthed us.
When ussr collapsed there were periods of complete anarchy such as working for the railroad that the ussr guaranteed workers pay and pension. Suddenly it was on the states to decide how to handle that. Someone’s lively hood was ripped from underneath them and they had to continue working for nothing if they even had a job to go back to.

That seems very similar to people today who have an eviction looming over their head in a few weeks and no job to go back to.

Another example is 1932 America during depression times. Hardship is all around us, step off social media for a minute..
Sure, and for different jobs I used other languages.
For one task there was a great python library so we use python and sent to it requests from PHP , some other task there was a java executable that worked the best so I called it from PHP, some other tasks there were Linux CLI tools that worked best so I called those, and some other task needed to use node and puppeter(a Chrome) wrapper - it was crashing a lot so we put it on a different server and called it from the main server PHP project.

So in real world projects you don't chose the tool based on coolness factor, if you want to solve a problem in the best way possible you need to use the best tool for the job.
Your first example isn't what I'd call indentation. "Alignment" maybe. I don't think anyone would expect that to work in a proportional font.

For the second one, I'd write it this way.

....arg3)

I prefer that even in a fixed width font.

> But in science fields, authors names don't really matter. The same outcome will exist regardless who is studying it.

I'm curious, how much experience do you have in scientific academia? Names matter a great deal in my experience. A lot of results are simply ignored if they're not backed by a big name, and many experiments will simply not be done unless there's a big name to attract funding in the first place.
The IKEA Tradfri "smart" lighting gateway will stop responding to commands if it can't phone home to some IKEA server. I noticed this when I changed my router to use NextDNS, which blocked the IKEA lookups. I was ready to return the device as broken until I realized this. I've also had issues with Bang & Olufsen speakers in the past, and inclined to believe it's for the same reasons.

I think it's insane that devices can effectively be bricked if they can't phone home. It's nothing short of waste, and I think environmental legislation should require device manufacturers to supply ways of disabling or overriding these mechanisms such that devices can continue to operate regardless of whether home servers are blocked or otherwise out of reach, e.g. company goes belly up, censorship etc.
Given all this, use a dumb old macro to make a simpler interface with a macro that expands to type safe code. That will save a lot of unnecessary syntactical noise and overwinter you until better pattern matching support comes along.

You aren't political, but your identity is, just as everyone else's identity is.

Paul Graham's post[1] on identity describes it much better than I could here.

Projects fail because you have misaligned incentives. The CEO gets a pat on the back when he announces a Technology Modernization project, The Executive team gets a pat on the back when they negotiate 20% off the Modernization Project with IBM. The IBM salesman gets his commission as soon as the deal is signed.

Then when the project fails everyone blames someone else. If you want the project to succeed tell all those people that they will get their reward at the end of a successful project not before it has even started.
Its interesting to me that in between the irreducible complexities of hardware/ x86 ops and real world domains C++ has emerged as an middle level of complexity in this stack. You can explore C++ features and syntax for years and there are entire podcasts and conferences that mostly just talk about language features and never run out of things to say. I wonder if some
programmers are attracted to this complexity either for the challenge or because they enjoy exploring abstract human made systems.
Anyone know a good mnemonic for remembering what each section is for?
No, I mean that classical determinism says "here is the current set of particle positions/momentums/etc, so we can work forward and predict everything from that." Superdeterminism says "if you do X then you will learn Y, so you aren't going to do X."

That doesn't necessarily mean signals going back in time. It could mean that the initial condition of the universe was set, such that nobody would do X. But that's still a way of the past (initial condition) being determined by the future, even if the future was just predicted via determinism. It makes physics teleological.

A common criticism of superdeterminism is that it eliminates falsifiability from science. E.g. to quote physicist Nicolas Gisin, "If we did not have free will, we could never decide to test a scientific theory. We could live in a world where objects tend to fly up in the air but be programmed to look only when they are in the process of falling." https://en.wikiquote.org/wiki/Superdeterminism

> Back of envelope calculation suggests income tax collected from a median family would be £50 per year.

Back of envelope calculation is definitely wrong.

I'm not necessarily disagreeing with you, I'm just saying that £50 figure is definitely not right, without doing any calculation. (OK sure - 50/0.2 = £250 taxed at basic rate above personal allowance. Which this year I think is £12k5, and median household income is surely above £12k75.)
Every task isn't a task that can be solved with 5 minutes of Python or JS. There are task that are straight up unsuitable for a language like Python or JS.
In guessing this is sarcasm given these tools predate modern social networks and serve such a fundamental feature as "Save Page" within browsers already.
>Deep reading has in large part informed our development as humans

As a statistic, reading is only significant in the past 200 years or so. Given that there was a similar kerfuffle a couple thousand years ago when we shifted from memorizing to writing things down, I doubt that this is too significant.

Literacy is also shifting. Growing up with memes and Instagram and Tiktok has produced a generation that is vastly more literate in design, photography and film.
That doesn't explain the rise in the graph this year, does it?
The borrow checker is one of Rust’s selling main selling points, and was what got me into the language.

This is just wild speculation and part of a frustrating pattern where all sorts of questionable behaviors by authorities are justified by other unrelated properties of the victims.
The basic difference is that she implied I&D work at Google was ineffective while he implied half his co-workers were unworthy of their jobs.

You don't see how variants improve readability over union+tag? Do you mean that you don't see a whole lot of difference below:

std::variant<int, std::string> setting;
setting = "foo"s;
setting = 1;

Compared with something like:

struct Setting {
Setting() { XXX }
~Setting() { XXX }
union {
string str;
int num;
};
enum Type { Str, Int, None };
Type tag;
};

Setting setting;
if (setting.tag != Setting::Str)
new (&setting.str) std::string;
setting.str = "foo";
setting.tag = Setting::Str;

if (setting.tag == Setting::Str)
setting.str.~std::string();
setting.str = 1;
setting.tag = Setting::Int;
> my mother's ideas of "proper" attire are somewhat like the dress codes of British Royalty that you read about in gossip rags. (Not too much skin showing, no cleavage on display, don't let your bra straps show, etc.)

This is an even more bizarre comment than TFA to me. Your idea of 'upper class' and the royal family is... curious. You certainly don't have to be royal not to want to wear (or your daughter to wear) a tracksuit with cash and a phone hanging out of visible 'under'wear..!
We're getting a bit side tracked but here goes... You can at least critique the ones where he describes what cryptocurrencies do and that cryptocurrencies would be some kind of cult. Paragraph 3 and the last one specifically. Those are opinions, but they are presented as facts. It's certainly true that some cryptocurrencies are marketed as investments but it doesn't describe the market as a whole, there are so many things happening in that space that I would describe it as a mischaracterization. The believer point you bring up is really no different from people believing in a certain stock, they're heavily invested and try to rationalize their choices. This behaviour looks like some form of cognitive dissonance. You see this quite often online in Facebook stock groups and similar groups, typical retail investor behaviour unfortunately.

It is the right decision for an highly infectious virus, that's passed through via small particles like aerosols and affects your respiratory system.

I know that no government has came forward to say it: but the decision to live with this virus was probably the most stupid mistake of the past 100 years, and comes in the time where politics and politicians were already seen for bad leadership and for being detached from the everyday reality.

For example, in my country, Portugal, we've been struggling with this and some weeks ago stricter measures were set in place - that came very late, after the national health system was on the verge of collapsing... what's the decision for the time of the year where most mobility is registered, Christmas?

"Let's stop the measures for 2 days, but be careful."

I shit you not. The most critical time for spread is when they let everyone go to each other homes.

The reason is simple, so no one can say they didn't let us celebrate Christmas, and they warned us to be careful - this is politics, it's not dealing with a pandemic and an health system on the verge of colapse.

---

So replying to your question, until there's no spread it's the right decision. Because living with the virus isn't good for the economy, and proof is countries with the virus controlled or with little to no cases, are in economic recovery (like we needed that data to know this, but still, there's something).

Not a knock on you but this reminds me why I hate speaking (writing) example via analogy.

There's so much horrible surrounding using "witch" as the noun, what with the traditional "hey, that's a nice plot of land you've got there" that proceeded the accusation.
