I'd say it is about answering the question "How many?".

It becomes natural to give a distinct symbol for each answer smaller than a given limit say 10. If you have symbols 1, 2, 3, .... 9 then it would be pretty obvious you would also want a symbol for zero.

The positional way of expressing numbers is a separate more evolved development of course.

In Roman numbers you had I, II, and III, ... So why didn't they have say '-' to symbolize less than "I"? Maybe they just expressed it with the word "none".
Yes, they pay short term capital gains taxed as ordinary income for equities. For futures they pay a blended 60/40 long-term/short-term rate, since all the futures trading is taxed that way (including for retail)
Co-ops have actually been having a pretty big uptrend in both popularity and market share the last decade. I wouldn't discount them so much.
Something I don’t understand:

Why haven’t their gains been arbitraged away? Conceptually what they do seems simple enough; and presumably you just need capital to do it. Hell, their own former employees could theoretically compete against them - as could many traders who would pay to learn those strategies.

So why are they still making so much? I don’t understand why their “advantage” hasn’t been arbitrated away into a commodity business.
It depends if you are getting new money or not. For a lump sum investment, depending on market cycles it's possible to structure the trade to optimize returns. If you assume that bear markets are every 6 years , there are certain simple integrals for computing this in which you input a certain starting capital and then a certain risk -free rate and then the capital is split between two assets like cash and stocks. When the bear market is triggered, you switch from cash to stock. [0]

But all you need is a bull market to 50-100x your money with 3x funds https://i.imgur.com/PF7XEaR.jpg

If 7/10 past decades are a bull market then odds are you will make good money.

Market neutral strategies are different though.

A calculation i ran to answer this problem shows that if you have $10k and split $3k of into cash that yields 3%/year and the $7k is put into TQQQ, which generates a long-term CAGR of 53%/year, approximates the actual returns of TQQQ .

So this turns the $10k into $1.5 million over 12 years, which is close to the actual result (100% or $10k invested in TQQQ at the start), assuming a crash happens every 8 years (modeled by exponential distribution and based on empirical evidence going back the past 100 years) and and then after TQQQ falls about 70% the $3k cash is then put into tqqq. After crashing, the above formula assumes that TQQQ races higher in order to maintain it's long-term CAGR, so buying the dip helps a lot.

So generally speaking, keeping 30% in cash/bonds equals the result of 100% fully invested if you buy the dip. The downside is if there is no crash you will lag.

There are various tweaks like above to improve risk adjusted returns. It's not that hard to do if you have a basic knowledge of calc and stats.
Just like that lever at a casino slot machine. A little dopamine hit each time you press next.
> I don't do stock market trading

You probably do, indirectly through an agency agreement, for example a pension fund that manages your money. Or even whenever you just buy an ETF to invest. The costs you're indirectly paying are lower due to the newer generation of market makers that have reduced transaction costs for you.

Investing in real estate for years is not related to market making stocks with a holding period of 5 minutes.

Almost all workloads are memory bw constrained, is the problem of our era. That is one of the biggest drivers of M1 perf across the board.

Optane is orders of magnitude faster than virtual memory, it is a complete OS bypass. I think you are conflating Optane used in an SSD and Optane on the memory bus. SSD Optane was a way to package and sell it before the rest of the hardware and sofware caught up for DIMM based Optane.

edit, removed snark.
Meh, TikTok is fine. If 83% of users are making posts of their own, that very much contradicts the notion that every user is a passive slack-jawed zombie. If TikTok is more interactive than its competitors and encourages a back-and-forth on popular topics, isn't that a good thing? And while there are certainly topics that demand long-form explaination, there are also an awful lot of cases where the current presentation is just gratuitously long (e.g. when I needed to top up my boiler up to pressure, a 3 second video could absolutely have shown me how to do it, but on YouTube everything is padded to 8 minutes instead). Kids these days are thinking faster and demanding you get to the point more quickly: again, isnt' that a good thing rather than a bad one?

Parents exploiting their children on social media is a problem, but by no means one unique for TikTok. And as a non-American I have zero sympathy for all the handwringing about how a shady foreign intelligence agency can be slurping up your personal information with no oversight; yeah, welcome to how the NSA has been treating the rest of us for our whole lives, a country that bugs the heads of state of their supposed allies has no leg to stand on here.
Again, any sources? I know of some gas storage caverns but they didn't come cheap.
and do not choke on carrots!
In short, no. TikTok is the first to have a public feed by default, not based on friends, plus the vertical swiping that forces you to see all the content it suggests. Its design and usage patterns are significantly different from all the others you mentioned.
If you work with many dedicated workspaces for specific tasks (for me, 16), then a lot of tabs on a machine can mean a perfectly reasonable amount per workspace. At any time I have between ~500 and 1k open across all devices.

I've built up a custom semi-madcap system, but like others, it works with my workflow. A script takes a snapshot of all tabs across all devices, saved to raw html so that it's fairly well future-proofed, and then I'm free to close any tabs that I can't get to right away. And then I've created a custom browser purely for being able to go thru the saved tabs, auto-organizing pages by subject or domain, with custom pruning tools.

I feel like page/tab/bookmark management is a core problem from the birth of web browsing that has never really been solved for most people. I have 3 main places for my core bookmarks, in Safari, Firefox and then also folders on my drive (still one of the few guaranteed cross-browser ways to store them without using online tools). This is all related to the tab problem above.
French happens to have a quartet of words that makes collation order obvious: cote, coté, côte, and côté. (That's the order my French-English dictionary orders those words; my French dictionary swaps coté and côte.)
You should go to an Alamo Drafthouse.

Honestly, I agree with you, there are a lot of people in the US that casually treat public spaces as if they are theirs alone, and this sort of rudeness and selfishness permeates the culture. Some subcultures are worse than others about this.

The only cinema in the US I don’t hate is Alamo Drafthouse.

There aren’t that many comments on this article yet but most of the comments that are here are pretty shallow and dismissive.

Unlike many posts, I read the entire article. I think the author does a reasonable job of describing how TikTok exploits human biology to increase “engagement”. They aren’t unique in this; Casinos have been doing this for decades; Zynga canonicalized this in games and social media has been lurching this way for over a decade.

TikTok is difficult to disengage from. For some it’s easier than for others. It would be interesting to see statistics to gauge users’ various level of addictive/compulsive behavior in the app.

Here’s a hypothetical question- should there be a limit on how addictive we allow something to become? We limit nicotine content in cigarettes; we ban or highly regulate many drugs. “Under the hood” the drugs we ban are affecting neural pathways; why should it matter if you’re ingesting a substance vs having similar effects via psychological manipulation?

I don’t claim to have the right answer and in the USA attempts to limit the app will run up against free speech concerns. But I do think that TikTok is bad for humans and bad for society.
The US tried but because it was Trump it was bad orange man mentality towards the ban.

I wish we could do away with social media in general. It’s horrible.
Also a convert to xmake. Documentation is a bit hairy, but solvable. The code is easy to read and contribute to.

I wonder how much of this is to do with cloud support.

AWS has never supported it. And on Azure/GCP it was only on expensive, high end types designed for SAP HANA and other niche use cases.

Shame as there was some interesting projects e.g. DAOS [1] that I would have loved to try out.

Python also has structural typing, often called duck typing - if you have a runtime-checkable protocol, an object will also match isinstance even when there is no inheritance.
Yep. Honestly this seems fine - pattern matching is ultimately just a function call, you can immediately see where it is (and hopefully even click through to the code from where the pattern is defined), there's no "magic" action-at-a-distance.
And then we are probably in a loop to tell our children the same thing, "don't use it" which really depends on how well one can do self-control, but I guess that's one of the hardest parts to many people.
> not claiming whether that’s justified or not

Spoiler: it's justified.
Invisible 1px GIFs for the tables...
That is not relevant to the general point. The article punchline is

> It uses manipulative user experience (UX) design to keep users glued to it. It is built to trigger compulsive use, especially in more impressionable audiences such as teenagers. It is also harmful to privacy.

Facebook / Instagram used manipulative user experience design, even if it didn't manifest as a vertical swipe or public feed. While the details may be different, the overall problem was just as true back then as it is now

Sure, but equally surely there's been no shortage of past articles raising similar issues about FB/IG/Snap.

You are over estimating this space. Fb is already competing here. They have begun an ad share revenue model with people who upload videos.

Some time ago, I used browsers as a meta-tab manager. Whenever there were too many open tabs in let's say Firefox, I'd switch to Chrome, then Chrome Beta, Chromium,...
But it was a bit hard to remember in which browser a particular tab was.
I was really looking forward to using optane as an ARC and database cache, along with a boot drive.
I think you've just added a 10th circle.

More specifically, it seems like you're solving a subset of dependency issues (mainly version conflicts), while making the other issues worse (e.g. keeping sub-dependencies up-to-date, ballooning disk space usage, less easily cachable requests to package repos).
Persistent memory though is a solution to a very common problem.

Especially for anything distributed you want that metadata to be super fast but also durable.
I'm not sure off the top of my head, but it depends on what exactly the specialization is. I'd imagine it's roughly around the salary of a software developer. However, education is a much larger investment, so a lot of that money is put towards loans.

Personally I was lucky and didn't have any debt graduating with a CS degree (actually an MS and BS), but if I were to do med school I would need to take out loans
This is article is so hard to follow.

The very aggressive bits are linked to articles supposedly backing their point with more substance, but those are same level think pieces who reference other think pieces who are based on misconceptions, and we never hit any solid ground.

For instance:

> The videos are in autoplay and shown in an endless scroll. These are features known for triggering addictive behavior and there were legislative plans in the United States to ban them.

Following “triggering addictive behavior” goes to thenextweb.com’s rant on autoplay.

which posits autoplay is “hijacking your thought process”, with a link to a medium post

Which on autoplay, explains that “Another way to hijack people is to keep them consuming things, even when they aren’t hungry anymore”, linking that analysis on the age old debunked Brian Wansink‘s bowl of cereal experiment.

So many other of these very assertive declarations have 3 to 5 levels of redirection to finally hit some disappointing justification. The general message being vaguely consensual, it’s hard to see what this piece is actually bringing to the table.
> “If You Want To Run Fast, Run Alone. If You Want To Run Far, Run Together.”

With all dichotomies like this, we’re never actually aiming for the extremes of far or fast but somewhere in between. There must be some ants finding new trails and there must be most ants travelling them. A hybrid approach is always the goal. Arguments for purity are fantasy, but can be fun.
I under understood what problem single-level storage was actually supposed to solve. In the real world you still need a notion of startup and shutdown because programs crash, memory gets corrupted, things get screwed up, hardware changes, etc., so it's not like we were going to avoid those. So, from a technical standpoint, why exactly would I want to merge my RAM with my SSD? The only thing I can think of is that it lets you achieve genuine "zero-copy" usage of data. Which, I mean, is cool. But is the overhead of copying read-only data from secondary storage to RAM really such a big problem for >90% of users to be justification for changing everyone's very notion of computing?
I see you're ensuring we understand Facebook and Instagram also optimize for engagement, I think the novelty here, for me at least, was the differences from Facebook and Instagram are quite significant.
Sooooo hard to get hired here. I’m convinced it’s impossible without a referral or something

I can see it, but not with myself. Maybe I'm getting old or just depressed into not feeling dopamine anymore but TikTok has the effect of only annoying me. Constant sound streams, fake voices, etc. It reminds me of Vegas in some ways...loads of people love the flashing lights, I just run away.

But I see it with my wife and daughter, it turns them into complete zombies.

All this to say, I don't know what it's like to speak effectively as a 'victim.' But as a bystander, I feel something should probably be done...I just don't know what. Anything this addictive cannot be good for society.
I nearly fell over in awe & respect for this comment. This is the heart of so much.

In this particular area, I feel the US is trying to regrow (rather than protect) it's asset, it's capability, and that's why congress realizes they needed to put down some money; to make it happen.

I wish this were merely protection. But alas, the US is in most areas non-competitve globally, with too big an obligation on the average & even below average corporation to make a not-cheap life liveable. Housing, healthcare, food, energy, all of it has gotten out of hand costly via ever deepening ever more exploitative privitization & now it just doesnt make sense to do industries here. Oops, mea culpa.

We have to pay companies extra to do work here. That's what this funding means, that's where we are. Because we dont support lur people, because we let private concerns take over without check.

This is sort of the discussion I wanted to hear from this thread. What separates a a product manager paired with a data analyst from say, a CEO or CPO (product)? Surely the PM and DS are better armed to make decisions with data and talking to users, etc.
And that significant difference is that TikTok is a Chinese company, not an American one. When you let go of the pretense, this is what all these articles and threads are all about.
The old version of the function could get security patches.

> The false dichotomy of "reasonable tabs vs. too many tabs" is an embarrassing result of slow evolution in software design. The fact that humans feel blame for the resulting behavior is 100% wrong and unnecessary.

Interesting, I see your point of view, but I guess my browsing habits are different.

Tabs are ephemeral in my opinion and can be closed without a trace at any moment. I can't rely on them being there, so I don't keep hundreds of them open with chains of context.

I have a tiny amount of reliance on the browser history to search and re-open pages if needed, or if I actually care about the URL's I'll add bookmarks, or URL's to a document/note.

The real reason why you shouldn't use this is that Python is wrong about typing and classes. In OOP, classes are not types; interfaces are [0]. ABCs are a
poor replica of this. Guido, having clearly avoided any relevant literature, states, in PEP-3119 [1]:

> ABCs are not intrinsically incompatible with Interfaces, but there is considerable overlap. For now, I’ll leave it to proponents of Interfaces to explain why Interfaces are better.

Let me try: interfaces are better because the protocol of an object isn't tied to its implementation, but in a properly encapsulated world an interface represents the information available about a class as a type [2]. A subclass may just be reusing an implementation without adhering to the same protocol, or two interchangeable classes might have no inheritance relationship.

Python is in a lot of ways a nice language, and I've certainly enjoyed programming in it, but many points of its design seem intentionally unobservant of prior work and research in programming languages, though perhaps it's equally an indictment of that research that the most popular languages ignore it so much. Typescript handles this much better, though neither it or Java eschew using classes as types entirely.

> store small amounts of data ... as graphical designs ... on pieces of ordinary printer paper?

You mean, printing out a picture?

...

Joking aside, if you tolerate lossy "compression", it'd be interesting to see what the characteristics of printing an image are in terms of image codec metrics. I guess the comparison would be with the "decoded" result, which'd be the raw output of the scanner. With modern equipment, it'd certainly be much higher quality than a JPEG encoded at the (albeit conservative) ~200 kB estimates given for the lossless formats.

This would also be a rare codec where future increases in decoder technology can actually increase the quality of the decoded output, assuming that the printer and scanner currently have similar DPI. I wonder whether that applies still to historical film photos or if digital scanners have already surpassed the resolution of the original media to the point of saturation. Would being able to "subsample" individual film grains allow extracting a tiny bit more detail?

That is basically where I am at with my relationship to caffeine/coffee. Sleep much better without it. But life feels a little duller without it as well. And then my first cup back after a long period of abstinence is absolutely magical. That feeling quickly fades after about a week of use though.

I tried limiting it to just once a week to see if I could capture the magic, but my discipline was lacking a bit, and even when I was able to stay on that schedule, it still felt like my tolerance was building.
