It may make more sense when you see analysts writing & sharing a lot of code sessions, especially via notebooks. Functional plotting ends up helping a lot! For big graph-y graphs, we made pygraphistry that way, which enables multi-cell flows like:

```

df = cudf.read_csv('1GB.csv').drop_duplicates(['user_ip', 'click'])

g1 = graphistry.edges(df, 'user_ip', 'click')

g1.plot()

g2 = g1.encode_point_color('risk', ['blue','yellow','red])

g2.plot()

g2.edges(cudf.read_csv('file2.csv')).plot() # reuse g2's color settings

g1.edges(cudf.read_csv('file2.csv')).plot() # ... or just g1's graph shape

```

Being able to 'fork' plots and interactively swap in different data / encodings is super great over the course of a session. You can always go back to an earlier one as you make progress. Likewise, you can rerun notebook cells and read them top-to-bottom without worrying too much.

So while we're looking at some V2 additions, maybe supporting R, and updating some of the core (more automatic GPU goodness!)... we're definitely keeping the compositional style.

Interesting nit: Libraries copying the original grammar of graphics can likely benefit from friendlier functional DSL presentation styles. As is, I think they make it much harder to read + write, undercutting much of the productivity potential. I love the academic concept of making everything a composable value, but doing naked composition over a massive namespace of diverse types.. is super confusing to read + write.

Learning from pandas & jquery, we ended up instead steering users to chaining for the typical case: `g.bind(...).edges(...).nodes(...).encode(...).plot()`. It's functional so you can always do `g_intermediate = g...` and likewise still do first-class GoG-syntax-style things with them of you really want `f(g._bindings)`. However, those are the minor case, and people doing them make code harder to read + write:

-- Reading GoG code is confusing: In `x + f(y)`, often unclear what x, y, and f(y) are, and more so in dynamic languages like Python + R that they're used in. In `g.bind(..).encode(...).plot(...)`, each composition is pretty obvious in the typical case, and you can always read back or do first-class in the atypical case.

-- GoG plot authoring is jarring: When doing `x + ...`, tab complete doesn't get you far. If tab complete does somehow kick in, you are dealing with a big namespace dump. Instead, I see people turn to google for almost every step! In contrast, table complete on `g.nodes(df)...` will pull up the most likely next settings to add, and then again for the arguments to fill into whatever command you pick.

GoG defaults to those for the typical case, vs atypical one, so a 2nd-class imperative API may be easier. But with chaining, we get functional composition without losing straight-line reading and tab-complete. Best of both worlds!
Presumably he's talking about asset inflation.
> There is no regulation mandating cookie consent overlays

Yes there is. A mugging is still a mugging even if the victim is "free" to give their wallet.

> websites are free to not abuse cookies to track their users.

You're free to not use such websites.

I dislike tracking and avoid being tracked myself. But this absolutely is a regulation and it's immensely disingenuous to pretend otherwise.
Yeah, well, Facebook did indeed buy some other social networking companies. I don't pay any attention to them, but how many people who don't use Facebook are also not using any of their brands?
They could add lots of disclaimers and dozens of I agree and I know what I am doing checkboxes but not allowing to buy certain stocks but only to sell them is like a partially blocked intersection with the only open road leading to a ravine. Not cool RH, not cool. It's really an insult to the legend of Robin Hood, he was robbing the rich and giving to the poor not the other way around.
The point is that a widely perceived conflation will have material effects on the involved organizations and that the conflation will spread to new organizations with each new incident.
> This is not solely UX designer's fault. This is also the team workflow's fault to not accommodate time for validating design.

We suffer from this greatly. Our app is complicated by nature. The designs that come from our product team turn a blind eye on the complexity and try to "make it simple". As a result, the product doesn't really work (in some aspects).

Every time we try to "validate" those designs, we're shut down "because simplicity".

Honestly I think product designers should go through a database course or something to understand that if there's a one-to-many relationship between to entities in real life, you cannot force it into a one-to-one relationship and ignore all potential corner cases. Suddenly 40% of cases are "corner cases" and the app doesn't work.
Reading the Dogecoin subreddit, when Robinhood stopped allowing users to buy AMC/GME, they just bought DOGE instead.

Or, those posters are DOGE-whales, if such a thing exists, who are pumping it.

Or both. Who knows.
This whole kerfuffle is a blatant publically advertised mass market manipulation effort. The reddit posts are still visible.

No one believed GME was worth over $40 a week ago, but now suddenly they pretend they honestly believe it's worth $300+? There's no book depth beyond the short squeeze.

If Valve made a full buyout offer at $100/share, management wouldn't take it?
I don't know how Cory Doctorow became so broken.

Why would he change to hanging with the cool bullying kids picking on the (rich) nerd who wants to go to Mars and have us all driving electric vehicles. It's a good example of how the internet breaks good people.

> That's why habitual bullshitters like Elon Musk hate shorts. Musk leads a cult of credulous worshippers who buy whatever he's selling. Shorts make bets that Musk's cultists will get deprogrammed. Musk uses this to sharpen his cultists' resolve: "they want us to fail!"

An alternate explanation of Elon Musks position might be the ongoing day in, day out attacks from Short Sellers on Twitter ($TSLAQ), Reddit, HN of his products to devalue them.

It's not just pointing out flaws. It's information warfare. They will and do lie.
>Ceteris paribus, creating more money reduces its value.

Ceteris is not paribus at all. If we're complaining about potential inflation rather than worrying about the raging pandemic and a full-blown depression like unto the Great Depression, we're in comparatively good shape!
There have been some bad bbs operations with criminal content that got shut down.

Top research universities get their students closer to the state of the art than do teaching universities.

For example, in recent years, freshmen students at Carnegie Mellon have learned more state of the art computer science knowledge than master's students at many teaching universities.

In addition, the capabilities of the freshmen computer science students at Carnegie Mellon are easily in the 95th percentile of all university students - enabling them to learn such state of the art knowledge.
The number of regular OpenBSD users that are not programmers is probably vanishingly thin. If my memory serves me correctly, there are features of modern x86 processors that it straight up doesn't implement on a don't-care basis, so it's pretty safe to say that nobody that has made peace with that is looking to deal with technology as maligned as Bluetooth when they're likely already buying hardware specifically to run OpenBSD.
We're about to find out.

The traditional thing to do is raise interest rates when things start getting hot.

But having "too much" economic activity is in some ways better than not enough with people being unemployed and such.

Institutional investors still win the day here, because Coinbase opened a private secondary market for them this week to buy shares ahead of the IPO.
No the community is genuinely toxic and that is the fun of it. It’s boorish offensiveness, not some ironic satire. This is what gives it its power however.
Given that they specifically introduced pagination to avoid issues caused by too-large single pages, probably yes. (tbh I would have passive-agressively made the "next" link 100px Comic Sans, but it's probably a good thing I'm not responsible for that)

We can discuss the trading halts separately.
Faster settlement means less time to discover and correct mistakes.

At a high level, nobody really likes trades being broken, but it's kind of a necessary "evil" that helps stabilize the entire system.

Let's say settlement happens in one minute, one morning a pension fund fat-fingers a price and loses 10 million USD to some student in her dorm room. That afternoon, the student then donates 1 million USD to an orphanage, pays off her grandparents' mortgage, buys 1 million USD worth of municipal bonds to finance a new baseball stadium, and buys several million USD in long-dated ETF call options. Some market-maker delta-hedges those options by buying the ETF. In response to the price move generated in the ETF, a large institution buys a basket of stocks and participates in the creation process with the ETF's issuer.

Now, what happens when the fat-finger is discovered and disputed? Too many things have changed for the SEC to break all of the trades and other transactions after the settlement. The student no longer has enough money to make the pension fund whole (even if everyone involved could agree that the most fair thing to do would be to limit the student to 100k profit and transfer the rest back to the pension), so I guess they're stuck with the pensioners having to live with that 10 million USD loss. "Oops, next time, make sure your pension hires a more careful trader, I hope you've learned your lesson" isn't very helpful advice to a retiree who's now out on the street.

That kind of discourse is addictive and even though you have a choice, we as a society don’t always allow kids to make their own choices — especially around addictive, societally harmful issues.
I've never had a bluetooth device that actually worked reliably. Granted, my experience is limited to mostly keyboards and mice. If the bluetooth isn't giving me issues, the battery is. No thanks. I'll stick with USB and wired devices.

No. They pay the trolls to make content moderation a misery

They don't want the content moderated, that's the excuse to shut down the thing that outsmarted them.

Also, I’m not sure exactly how you meant it, so I won’t direct this at you, just generally...

I can’t get over the techbro straw man of the “lockdown” I’ve seen thrown around a lot. First, compared to most of Asia that actually got this virus under control, we have never really had much of a true lockdown here.
Second, it’s not the lockdown, its the pandemic. In most areas economic activity dropped off well before any lockdowns and has remained subdued regardless of lockdown duration as long as the virus remains active.

That is - the economic activity drop is more correlated with level of virus outbreak than with any government orders.

In NYC, everyone I know got sent home a week or more before any city/state lockdowns started.

The only time offices were mandated to be closed in NYC was about 8 weeks when we had refrigerated trucks parked outside hospitals acting as mobile morgues, and the National Guard picking up 100s of bodies per day of those who died at home.

For the most part companies have kept people WFH because they can get close to 100% productivity with close to 0% absences due to disease & death.

The mental health angle of more time spent at home, I still think is a wash. For every extrovert craving lording over a conference room of coworkers, there’s an introvert enjoying reduction in forced social interactions. Lots of people actually like their family & enjoy spending more time with them.
Unrealized gains don’t exist, and read their TOS, this was inevitable. Robinhood is just one of many brokers limiting their exposure to a highly volatile stock of little intrinsic value with temporary trading halts.

You are lucky the NYSE hasn’t shut down BME trading for all of February. Yet.
I've heard people 'just ask questions' or 'make observations' or similar a million times before, and you most certainly have comments that fit the profile of what you've been arguing in favor of. It reads like a deflection, as a result.

Moreover, this is kind of what I mean by comments that aren't falsifiable, that don't really add anything. You're not giving me anything to work with when you gesture vaguely to theoretical comments rather than specific examples. All I have to go on are yours. And yours make for very good counterexamples.
Thanks for the response saghul, we’ll get in touch.
Robinhood lost trust when they initially lied to their investors about why buying was halted. (Saying they cared about the little guy and these stocks were too volatile for them to handle)

Then they came out and said it was a liquidity issue. If it was simply a liquidity issue, why weren't just margin orders halted? Why did they stop people with cash in their hand from buying stock?

None of Robinhood's statements provide a full explanation.
People are within their right to be absolutely livid at this moment and demand answers.

Some facts:

1) There is a conflict of interest when Robinhood routes the majority of trades through a high frequency trading firm that has an interest in short positions. Citadel bailed out Melvin who [probably] illegally naked shorted 150% of the float.

2) The CNBC interview explaining the liquidity issues that aired today was filmed yesterday.

3) Mainstream media has been feeding lies to the public. Who is buying the stock? (It's foreign entities who hate America and capitalism!)
Will the SEC come after the little guy?! Can they sue these investors?! (Absolutely not. Why the hell are you trying to put fear and doubt in the heads of these people?)

These facts along with Robinhood's BS explanations lead people to believe that the reason that this happened is simply that the WRONG PEOPLE LOST MONEY.
I think you and GP are conflating "repairability" with "upgradability".

The only two components in a laptop that are essentially guaranteed to fail in a short-ish timeframe are flash storage and the batteries. As long as these two are replaceable, I think a device is reasonably "repairable".

While there's a definite chance of the CPU and memory etc. failing, I think for most people the trade-off in size and weight to accommodate sockets aren't worth it from a repairability perspective.

That's where I draw my line, anyway. Flash storage and batteries are essentially guaranteed to fail in 5-10 years of use, and absolutely need to be replaceable. As long as the build quality is decent, the rest can be integrated.
That is what they are saying, isn't it... while they are promoting stocks they have a financial interest in.
Mmmm, Count Chocula...
DeGiro is an excellent broker, though. They're basically _the_ serious broker in Europe - for wealthy Europeans it's either them or IBKR.

Also, exchange rebates are usually very small amounts of the total trade, so for people who the fixed fees matter the most (people with less money in their account) the rebates would be insignificant.
So if we narrowly define innovation in the way the article does, I would take it a step further to say that innovation isn't all its cracked up to be and we can greatly improve our technology without innovating. If innovating was so useful we would've kept going after 1978 and since we didn't I am satisfied to conclude that we knew better than to waste our time chasing this defined version of innovation.
I'm not an expert but how I read it is: market makers currently can sell a stock without owning it. All is well as long as they buy it back by the end of the day as settlement takes 2 more days.

If settlement was instantaneous then the market makers would have to already own a bunch of the stock in order to sell any. Owning stock requires capital. Similarly if they wanted to buy more stock they'd need cash on hand.

That would be my question, yep. Beyond mind-share and goodwill, what does Grafana gain here?
Dark patterns are everywhere and I'm afraid not enough people are raising a ruckus about them. For example, the "Google Pay" app in India, which works via the UPI system, shows its own "scanner code" in the app as opposed to the standard UPI QR code. Furthermore, you can't discover where the UPI QR code is, if you want to pay using BHIM - an app that works directly with UPI payments. If you're using GPay too, then you can access the scanner code. If not, you used to be able to select the UPI QR code from a menu and scan that. However, later updates have hidden that - not eliminated it, mind you, deliberately hidden that. You have to "swipe left" when you see the GPay scanner code to get to the QR code - not at all a discoverble act. My wife discovered it by accident after we were puzzled a few times about where the QR code that used to be accessible went (both of us use BHIM). As a consequence, folks who use GPay do not know about UPI. This is, in my books, malicious design. Hanlon's razor would ask me to try "stupidity" first. But no. This isn't stupidity. It is downright malicious (the benign term being "dark pattern") to do this .. at least at Google's level.
I think this is why the spreadsheet is the killer productivity app. It's just a keyboard enabled information management tool, power users can take a spreadsheet really, really far. Entire businesses rest upon spreadsheets.

That is coming from someone who considers the need to use a spreadsheet as a marker that my job scope had gone awry. Love spreadsheets, hate managing information.
There's a bit of a cult classic book, "Pocket Ref" by Thomas Glover, and its big brother "Desk Ref." They're just books that attempt to provide reference tables for most of the things you'd need to look up throughout a wide variety of technical fields, but especially mechanical trades. A random selection of the contents includes "Densities of Gases," "Plywood & Panel Grading," "Canada & Mexico Postal Abbreviations & Capitals," "Solid Figure Formulas," "Commonly Available Pumps," "Welding Electrode Amperages," etc. Sort of a monument to what's possible in a reference work, and cheap insurance to throw in your toolkit or vehicle if you do any kind of field work for when there's no cell coverage.

I also have a book of mathematical tables, mostly for historic interest, but I think there's also some value in working from trig or log tables as I find looking at the table a few times helps you develop an intuition for estimating the function a lot faster than the attempts some textbooks make.
I was with a group of Coinbase employees that did the math on this in about 2018. Even then, Coinbase was a bit ahead.
Well luckily the groups fleeing to host servers there have no reason to do that. When they want to criticize Putin they can do it from American servers.

>Why are SDFs useful at all?

Meshes and bezier patches are boundary representations with no information of the volume they enclose. Imagine you'd like to cut an object out of smoke or clouds. SDFs enable you to cut out arbitrary volumes from any material. This is more realistic than skinning a mesh object with textures, especially with translucent objects.

> So why do we need neural nets to represent them?

You don't. I didn't notice render times, but "interactive frame rates" would be lacking.

Most SDF primitives and their compositions are not analytic (from use of abs, fract, etc). Differentiation by finite differences is most common. Few are using automatic differentiation. I don't quite follow how back prop would produce the surface gradient, but I doubt it would be faster than these methods.
Out of curiosity, if you'd like to share, what were the degrees?
While I won't say the punishment is fair, it would not surprise me to learn people we're selling themselves for stock tips/shares on the group.
A few years too soon for the mention of the best of pendulum clocks, often noticed here... the Shortt-Synchronome Clock. A clock that once adjusted, was better than many low end quartz oscillators in terms of stability. (2.31 ppB)
Would you have preferred that if they were unable to take new buy orders, that they also prevented people who already owned from having the ability to sell it? While everyone else "sold ahead of them" and the users lost money "because Robinhood wouldn't let me sell"?

Robinhood may be able to control what happens on their own platform (typically heavily based on regulation), but that doesn't mean they can stop buy/sell activity on the whole market.
>It's why have they all decided to act right now, just as this gamestop maneuver is happening?

the demonstrated power and financial success of WSB, even if fleeting and temporary, provides a lot of implicit credibility and validation to the "retard/YOLO" non-PC culture of WSB. The modern society worships success, and the people pay oversized attention to what successful people do - like what they eat, how exercise, how they stay motivated, etc. And now instead of respectable, successful, well dressed, educated, smart, cool, etc. Wall Street-ers a bunch of "retards" crawled from under the rock, teared a new one to those Wall Street-ers and got right on top of that podium of success veneration and idolation (like the "nerds" did 20 years ago with their tech startups). No surprise all the establishment (which these days naturally includes successful "nerds" of the previous generation) fights back. The established interests are always scared of changes, and especially when changes look like paradigm shift (while we wouldn't know for quite some time whether it is a true paradigm shift or just an aberration, the scare is real)
