As an MM, you manage your spread, the distance away from the midprice (say) that you're quoting. The tighter your spread, the more trades you pick up, the more profit you make against noise trading. The looser, the fewer you pick up and, importantly, the more time you get to react to seeing informed/toxic flow.

So that's a huge part of the game, try to detect toxicity early and widen your spread as much as needed to stay out of it. In practice it means that whenever toxic flow hits a book the book's spread (the distance between the bid and ask) will widen as well as the new price is sought.

Pay for Order Flow is a big tool here because you pretty much know that all trades done on free brokers are non-informed. If you subtract that out you increase the signal-to-noise ratio on predicting toxic flow.

Finally, lets say you are hit and take on a bunch of toxic inventory. Now you need a place to dump it to. Your options depend heavily on your situation, but you might either hope you have complementary non-MM strategies which can absorb this inventory or you might hope that you can quickly shovel it off to another venue (another exchange, a dark pool) where you won't get hurt so badly.

And if you can't do any of that, you take a loss.
I was obsessed with this game too. Was a care free time in my life
I'm on your side ... The defeatism is real, I can't really name a single win. GDPR? Protests against SOPA/PIPA? Net neutrality? Apple not giving up passcodes to LEO (they do)?

I've attempted to educate friends/family on tech privacy concerns, but nobody cares, even my friends in the industry. I have many tech friends that won't even modify their home network, let alone ditch FB or Google or Snapchat or Tiktok. Ultimately, computing and the internet is untrustworthy and always will be so. I don't possess the knowledge or time to assess every line of code or dependency in a project. Let alone backdoors in chips, hardware, and my ISP providing a line to the NSA.

Abstinence + sabotage of platforms is probably the only way. Keep the corporate developers busy fighting spam, fraud, abuse - make it unprofitable to build spyware.
That isn't weird. It's what they've been taught. CS departments started teaching Python to other departments because of its ease, and it stuck.
Reddit is just Digging itself a hole. (See what I did there? :) )
Precisely. We are constantly bombarded by messages to buy buy buy. Fill that hole in your life with plastic crap that will surely be the thing you were missing that finally makes you happy. And when that doesn't work, well, just buy some more!

The trick they pulled is telling us all that inconvenience is bad and needs to be eliminated, but what I've come to see is that life happens in inconveniences, and consumerism tells us we should trade our life for their junk.
Fantastic! Can’t wait to upgrade my servers and desktop.

Huh. I came up with this independently years ago. Unsurprising others would. Clarke's quote is infinitely useful in defining razors.
* If War Means Everything, It Means Nothing *

If we cannot define war, it is difficult to recognise the differences between war, conflict, and competition.

It is a historical fact, that german foreign minister Hans-Dietrich Genscher, assured "NATO will not expand to the east".

That does not make it any binding international agreement, sure. But some of those words existed.
Wouldn't a good answer be "run more experiments in parallel to find product/market fit faster?"

I'm not saying it's easy (or possible) in all cases, but an extra $2.5 million before you have product-market fit doesn't sound like something that is impossible to utilize in an effective manner.
Congratulations to the Debian team!

An important change appears to be the inclusion of non-free firmware by default in the official install image for the first time, as a result of this vote: https://www.debian.org/vote/2022/vote_003

Intriguing. I feel a little torn on this. One the one hand, I appreciate being able to install Debian from an official image onto a bothersome device. On the other, I can't help but feel we're losing something when even a purist distribution like Debian is forced to concede in the fight against proprietary blobs.

Edit: dropped the word 'kernel' from 'proprietary blobs', as rightly picked up by kind commenters below.
Or resource allocation.

But then, these navel-gazing critiques of capitalism only work in a vacuum. Why do these men in suits assemble in these temples of finance to perform these arcane rituals, to utter these numerical incantations? It's weird, right? They must be searching for god, or maybe they never got enough love growing up. Couldn't have anything to do with actual human experience telling us that the market is the most resilient and efficient (if not always the most fair) way of deciding, as a society, how to employ our scarce resources in a useful way. The people who buy and sell abstract claims on collective human endeavours must do so out of some deep-rooted spiritual malaise and it can't be related in any way to their own very mundane desire to put food on the table and maybe even spend a couple of weeks a year in a tropical location with people they love.

No, we should probably get rid of all this weird ideological baggage. (What do we replace it with? Oh, that's not my department...)
They are currently overloaded, already upgraded from a 16€/month server to a 67€/month one, but still having issues. Sudden influx.

here is a not-a-doctor-but-a-user advice, take it if you want, i had this "little pebble" in my heel a couple of times and i was told that i had this condition....

A doctor i happened to know told me that it was a form of "gout" and that people mistakenly do all sorts of exercises and some even take up surgery but that's totally unnecessary.

a single tablet of "Febuxostat", the most cheapest, generic one gave me enough relief that the second tablet just eroded it completely.

If you are facing this issue, please take just one. Its very safe and you will either feel relief from the first tablet or not. You don't even have to consume it in multiples.
Yeah, the whole post has a very “I am 14 & very smart” feel to it.

Their only really good point is that they don’t use the API so aren’t bound by its terns. That’s a good, solid, point.

The rest is… not.
Dialup services were available. Most had little to no internet connectivity. The few services dedicated to internet access were not mainstream yet. MS was preparing to deploy MSN 1.0 with no internet because that was just a hippie fad.
How is your job search going?
I'm trying to gauge whether the job market is improving - it seems to me that it is. If you've been affected by a layoff, how is your job search coming along? What are your feelings about it?
This is a distinctly Western perspective: that intent matters. Ezra Klein has a whole podcast episode about this from a week or two ago.
> but because they do it badly, and the clickbait is insufferable

Well, then, who does pop science "right"?

There's no shortage, of course, of 30+ page review articles on every scientific topic imaginable. And if someone has a few days, a freshly minted STEM degree or years of related experience, and a compelling interest in the topic, they can just pick up one of these review articles and go to town.

But that isn't going to fly for the general public, not even close. And not just because of the mathematics, dry passive-voice language, lack of context, times new roman, and gratuitous expert jargon. It's just too much.

So, what do you recommend?
It's easy to make things cheap by making them wrong.

Making things fast though is a whole other world.
There are multiple people in the comments here that are defending the Reddit CEO. Sadly him doubling down seems to be working...
A deep dive into modern UI programming patterns
Anyone who thinks reddit had anything to do with "microblogging" clearly doesn't understand what Reddit was. Hell, most of the good subs aren't even aggregation, but original content.
A few anectodal things from ekşisözlük claiming people were able to look up the medicines they are taking. Nothing conclusive and I didn't really have the chance to do a deep dive with my current bandwith. The files are supposed to be around 64GB.
It's stuffed with anecdotes explaining how to succeed in an extremely complicated and competitive business. With a very small bit of creativity you can construct clear analogies to white-collar work. Here's an example, in a story about a restauranteur nicknamed "Bigfoot":

> In Bigfootland you showed up for work fifteen minutes before
your shift. Period. Two minutes late? You lose the shift and are sent home. If you're on the train
and it looks like it's running late? You get off the train at the next stop, inform Bigfoot of your
pending lateness, and then get back on the next train. It's okay to call Bigfoot and say, 'Bigfoot, I
was up all night smoking crack, sticking up liquor stores, drinking blood and worshipping Satan... I'm going to be a little late.' That's acceptable-once in a very great while. But after showing up late, try saying (even if true), 'Uh... Bigfoot, I was on the way to work and the President's limo
crashed right next to me... and I had to pull him out of the car, give him mouth-to-mouth... and like I saved the leader of the free world, man!' You, my friend, are fired.
I fondly recall how once, after a long-time waitress arrived back late from vacation, claiming her
flight arrived fifteen minutes after scheduled time, Bigfoot called the airport to check her story and then fired her for lying. Treating Bigfoot like an idiot was always a big mistake. He lived for
that. In the man's three or so decades in the life, he'd seen and heard every scam, every bullshit
story, every trick, deception, ploy and gag that ever existed or that a human mind could
conceive-and was always happy to prove that to anyone foolish enough to try. If Bigfoot asked
you a question, and you didn't know the answer, he always preferred an 'I dunno' to a long-
winded series of qualified statements, speculation and half-truths. You kept Bigfoot informed of
your movements. He would never allow himself to fall victim to 'manager's syndrome'-constantly
watching the clock, wondering if and when his employees were going to show up. Where Bigfoot
ruled, he knew when they were showing up: fifteen minutes before start of shift. That's when.
Bigfoot understood--as I came to understand--that character is far more important than skills or
employment history.

This is of course a very blue way to tell a story, but it also sets a very clear model for what a demanding and competent boss wants out of his competent employees. Anyone in the corporate world who is always 15 minutes early and says "I don't know" instead of BSing is going to be a rare asset to any company, and that's just one dimension of what Anthony Bourdain outlines as a competent chef in his book.
I wonder who is using Discourse successfully and how they measure that success. If your project is awesome but your forum is appalling, you will still get some users who put up with the appalling forum in order to collaborate on the awesome project.

Discourse only "supports" 4 browsers. If you use any other browser you get the frankly ridiculous "upgrade your browser" message. Faking the user-agent shows that the software works just as well (or badly) on other browsers so this is just shoddy behaviour.

Discourse is slow, unwieldy and degrades to almost unusable with JS switched off. It's pretty much the worst forum software I have used. It is not an application to hold up as a shining beacon of what OSS can achieve, unfortunately.
Didn't expect for shiny-server to be mentioned so prominently. I might actually give Debian a shot for my personal machine. The five years of updatea sounds great, the LTS option is the main reason why I went with Ubuntu so far.
Google is unlikely to make that argument given that their entire search monopoly rests on abusing exactly that.
Thanks for clarifying. I was speaking about lay people, like me (I'm not a historian, except only as an amateur of mainly ancient history).
I had a look around, but couldn't figure out who's paying for kbin.social / will pay for it in future.

I also didn't see any ads, so... I feel I'm missing something important here.
Never ceases to amaze me. There is all kinds of things wrong with Debian I am sure. But at the end of the day, what that community does is mindblowingly impressive.

Much gratitude from a Slink-and-a-half user, back in the day.
The question is: Why won't the companies pay well? Good quality IT gives massive savings/profit, there should certainly be enough left over to pay the people who actually did the work. I think there is an attitude in Europe of workers not deserving high compensation, by the virtue of them dirtying themselves with work and not belonging to the owner class. If you lose talented employees, so be it, they simply don't deserve getting paid better no matter how much money they bring in to you.
> I'll bet modern engineered speakers will beat those high quality speakers, at a fraction of the price.

You'd be surprised how shitty most "modern" speakers are.

Size is still king. Doesn't matter how fast your fancy microcontrollers are. The big-ass cabinets from the 80s and 90s still sound incredible when you put them next to the typical experience you'd find on the shelves of Target or Best Buy.
> If we define aligned as moral, it's easy to disprove that humans are aligned by default

What is the quote? "All power corrupts, absolute power corrupts absolutely". I am not sure any human would remain moral once given absolute power.
Not all change is good, progress for progress' sake is an example of this. The more "visual and much more stimulating" nature of those "modern social networks" stands to "dated" mostly text-based communications as "high sugar deep fried processed" food stands towards "traditional" food made with fresh ingredients. Sure, the kids will gorge themselves on it but they'll end up as obese adults suffering from low insulin sensitivity a.k.a. diabetes type 2. Twitter itself already resembles a Twinkie compared to the home-cooked lunch served by NNTP so it is not as if copying the Twitter model is something to aim for.
A bit of background around the company: They received the largest fine (until that point in history) for trying to use this to front run the market from their dark pool.

Ironic given many third party app users would likely pay $60-100/year to continue to use their third party app. Now, we'll just stop using reddit and be sad about it.

Missed opportunity due to... what? Desperation at Reddit?
why though? librewolf is head to head with brave so why not prefer that if you don't want to help google impose browser monotony on the internet by forcing even their competition over to chromium?
if you care about your privacy and want to help build a more open internet, why not support librewolf if you have ideological issues with mozilla?
That might be because some interface(s) are supposed to show something like demo data when you enter an ID number. They want a membership for more. But this is speculation. I am sure we'll find out in a few days when it's already forgotten.
Silly question, because I’ve been dealing with exactly this complexity in FreeRTOS and haven’t been able to solve it, but if you’re doing while (!preempted) doesn’t that mean that the preemption can only stop the loop after the current iteration of it finishes? I’ll dig into your code, but I’ve not been able to think of a (user space) way of cancelling a blocked thread (such that the thread is properly cleaned up/scope closes and destructors are called) myself
Maybe some people could do one thing and other people could do something else? Just like today?

Lots of people can do work that isn't part of a startup. I'm fairly certain startup employment of e.g. SEs is nowhere near general employment of same.
> Numerous people are currently sitting in jail in Saudi Arabia for having posted tweets critical of the regime under their own names. Without HTTPS, jails around the world would be a lot busier if authorities could see everything that their populace reads online in clear text, in order to build dossiers on who is most likely to be a dissident.

Indeed... When one lives in such regimes, to say that appears to be an utter truism.
So why do you believe that the visual cortex works similarly to an ANN, but the rest of the cortex doesn't ?!

Of course we know that CNNs and the visual cortex both learn similar low level orientated-line feature detectors, etc, so there is evidence of them operating in similar fashion.

The thing is, the entire cortex is a very regular structure with the same 6-layer architecture across all areas and same thalamo-cortical loop connectivity. So, it's very unlikely that one area of cortex is operating in a fashion much different to any other area. If you're willing to accept that the visual cortex has close parallels to a CNN in terms of how it is operating, then that is highly suggestive that the abstraction of a CNN/ANN does indeed capture the essence of at least some aspects of cortical operation.

Nobody is saying that the brain and ANNs are exactly the same, but there seems to be close enough correspondence to at least some types of ANN architecture that lessons learned there can inspire understanding of the latter.

Another example - before seq-2-seq neural net language translation, would you have believed that an a variable length sentence could have it's meaning captured by a fixed size sentence embedding ? Intuition might have suggested that some complex structured variable length representation would be needed, but now we know that's not the case, and it helps understand how similar representations are likely also used in the brain.

What point does replacing a 2yo iPhone serve aside from spouting conspicuous consumption on HN? The 2.5yo iPhone 12 has better single core perf than the latest gen Samsung Galaxy S23, supports 5G, has a perfectly good display, and will get updates for years to come.

I'm still using Firefox and it works great.

The tricking people to sign in stuff is nefarious and is a more recent and growing problem. Google even gets away with it through iOS by forcing app logins/"authorization" that then results in the user logged in to Google on Safari. The whole Chrome logging in if someone checks their Gmail is terrible.

If your computing experience solely comes from a non-tech role in a corporate work environment where your employer legally owns your devices and they are remotely controlled and monitored, then all of this may seem fairly mundane. Otherwise, it is concerning anyone on hn would think what is going on here is ok or does not need to be actively avoided.
I’m registered on the main instance (https://kbin.social/).

They are heavily overloaded, the dev already upgraded the server as high as possible (16€ to 67€ per month), but that only helped at the beginning, now that some are saying to join kbin instead of lemmy (because of lemmy devs apparently being tankies), the server is essentially close to dying. This is also an issue with some lemmy instances, earlier today I was unable to reach feddit.de.
> Show me CONTENT

True for every content platform. If the website just spews meta without showcasing the innards immediately (even just screenshots) it seems suspicious.

For kbin, they link 5 instances on top, but that doesn't connect the context.

> The ad was one of a few important influences impacting my own decision to give birth in May 2011 to my second child, a healthy girl, at home. As it did for others, the commercial had a positive personal impact on my life.

She clearly says that she has been influenced by propaganda. Maybe you should have read the article first.

Human beings can be rational and irrational at the same time. Yes, they can be trained to be somewhat more rational but it is silly to think that there are people that make purely rational decisions. Also no healthy individual is just running on pure animal instinct, everyone is capable of some form of rationality.

So yes, agreed there is no small class of rational people that should rule us for the greater good of all.

The practical consequence is to understand that we ourselves are irrational and if we don't think so, we are just fooling ourselves. And if we want to enact (hopefully positive) change in the world, we need to speak both to the heart and mind of other people.

I think it's disingenuous for the article to provide these prompts as evidence for their argument, yet use a subpar model with no comparison to gpt4. This article is only convincing in that it shows how far behind bard is compared to gpt4.

I thought Huffman coding was obsolete, arithmetic coding replaced it. It allows for fractional number of bits per symbol, so is more efficient.

> If you need to raise money to stay afloat, you're not going to be successful (except in a very minority of cases like Airbnb and Uber but your startup will most likely not be at that level).

That's ridiculous. Some products need lots of development before they are ready to make money. You can (and probably should) still do smaller iterations to check market fit, but it's entirely possible to create products that take a lot of investment before they are able to make sense on a unit economic level.

Hell, ChatGPT, one of the most successful products in history at this stage, was the result of many years of work and research.

What you're saying isn't even just true of innovative startups - if I'm starting a restaurant, I'll often need lots of investment and multiple years to make back that investment before the restaurant makes sense, if it ever does.
