Correct me if I'm wrong as I can't use their platform, but Robinhood doesn't act as a bank and mercantile payment processor do they? They only do trading. Coinbase does all the things I mentioned and more.

GP was probably expressing concern that it may be possible for Coinbase to be wiped out in bad leverages which would affect people that don't trade at all.
The point in discussion is what is a quality message? And what is considered garbage? While men think they are unattractive when they don't get matches in dating apps, women think they mencare unattractive when they can't match the best looking guys in the app.
A new GPU is able to calculate ~50,000 million MD5 hashes per second, an MD5 hash is stored typically on a 32 bytes hex string. If you want to store that you'll need more than 1TB per second: https://gist.github.com/Chick3nman/bb22b28ec4ddec0cb5f59df97...

I used MD5 because that's the typical hash you find unsalted on leaks, but if you do the math with others it is almost impossible to find an example where storing beats using a GPU to crack (even an older one) for a couple of hours.
Coffee Meets Bagel implements something like this, where each person is presented a small number of people per day, regardless of whether you choose to match or not. They seem to have had issues with the quality of number on it recently, but I was a big fan of it in around 2015-2017

That's not logical that's thinking linearly. What are you even swiping at if you are swiping at everything?

This is why there’s an ever evolving art of progressive/lazy image rendering. There are several techniques that involve populating a blurry or even polygonal version of an image that eventually resolves to the real image. The ultimate payload is larger, and the time to render is greater, but faster UX gratification is more satisfying.

This reminds me of a counterpoint to my top-level comment of how frustrating Apple’s progress bars are: way back in the early OS X days, they did user tests that showed people respond better to longer running progress disclosure than shorter running real progress. So they literally baked a delay into the OS X boot process that would make booting take longer but show a more predictable progress bar.
Thank you for the explanation, I appreciate it.
I'm not sure how buying products not remotely as good has any effect whatsoever on making anything "just as good".
This seems more likely than Charter, ATT, et al. investing massive amounts of cash into their networks. I think there would be massive PR campaign if the actually almost doubled available bandwidth in a year. The capacity was always there, they just needed to be paid in order to open it up. I upgraded from 200/10 to 600/35, they just flipped a switch.

I use a hybrid complex event processing system that is mostly custom built, as well as a large scale data ingestion framework that takes in around 2-3GB of price data and other relevant information every day. It took a really long time to get this part of my setup working because without a decent way to kick off a process that subscribes to this data easily, everything else is going to be a huge pain in the ass.

I put on trades on a 2week-1 month time frame, and aggressively sell winners and use stop losses to get rid of shitty positions. I use GARCH, ARIMA models, and have recently been playing around with some more exotic ML techniques, but I've found that momentum trades work the most reliably.

I'm working on a SaaS API to try and make some money off of my data collection systems, but that's still in the works.

EDIT: I try to identify interesting individual options that are, according to my model "mispriced" given a few signals. I seek out multibagger options. Most recently, I purchased the $PLTR 11/27 $22 strike calls two days ago, and made a killing (was around a 6x gain). If you are methodical in your data collection processing, there's a lot of valuable information that can be obtained. It just requires lots of data munging (which, honestly, is so painful all things considered). But turning 1k into 10k is a wonderful experience, especially if you can reproduce it.

I have taken the well known 30-40 advanced options strategies and created a dynamic programming algo to basically run through every single listed security and every reasonable combination of options that would yield these strategies, with some filtering to make it computationally tractable, and then computed what the collateral costs would be (for spread trades, for ex.). That creates a reasonable doable list, and then I run a straightforward backtest. From here, I either pursue a trade or not. I like the idea of fully automating this stuff but its just not there yet. In any case, systematizing a lot of the boring crap is a great way to more deeply understand the landscape. You're never going to compete with execution-based firms but you can definitely take a view based on underlying fundamentals/macro landscape and then tune a slightly longer based system appropriately.
Going from a 60% swipe rate to a 5% swipe rate doesn't mean going from a dozen awkward dates a month to one good date a month. It means going from one or two awkward dates per month to zero dates per month.
No they couldn't. That would be equivalent to saying committing a crime creates a right to privacy that didn't exist previously. And if it wasn't part of their official duties, why would the department/police union be defending the officer?

You do sometimes see cases where a police union defends an officer accused of some crime, but that's usually because they're putting up some BS story about how they actually were doing their duty, eg an officer busted in possession of drugs who tries to argue it was actually an undercover investigation of the drug scene.
To my anecdotal experience, more like a market makers dream. If you do speculative HFT then for the unexperienced you may get crushed by huge slippages when exchanges crumble under a load. Notice that exchanges in the Bitcoin world either do not, or simply don't care, to guarantee availability during spiked trading. I don't say alpha is impossible, but probably requires certain degree of comprehension.

Oh wow this is great, thank you!

I hadn’t heard the T-Rex description before. It perfectly captures the look of every standing desk I’ve seen. It’s amazing how much the four legs changes the look and feel of the desk.

Since you seem to be in the know: Do you see any of the more B2B type companies (or designers) focusing more on the consumer market in the future or is the opportunity in selling to corporate offices going to keep things as they are? It seems like a lot of the design talent is focused on the corporate office space and needs. For example this C9 looks to have a rail system line etc built around the desk, which makes me wonder if different design choices would be made if the focus was more for a home office setting.
> For all metrics my rule of thumb has always been to just do my job as best as I can and ignore the metrics. If a manager ever says anything about them, I ask them what they think of my actual performance.

I was like this once. But metrics are not always going in pair with actual performance or logic for that matter. And sometimes manager's hands are tied, even though your performance might be good, manager sees your good work etc.
That happened to me actually, long story short I was given a lot of complicated cases which resulted in "bad performance" based on case/time ratio and by newly implemented corporate performance enhancement program I was downgraded "temporarily" to do grunt work that I magine was like in primary school punishment: "so I had time to think about my behavior".

Apple is definitely fashion-driven, but I think they also produce some hardware that is much better to work with.

The touchpads on Apple laptops are much better than what you can find on other laptops. The screens are much clearer. The weight isn't too much, and they're not huge; easy to move around with.

I'm very keen on getting back onto Ubuntu, but there's just no equivalent laptops in terms of hardware.

Good math... Aluminum comes in different alloys, this is likely 6061 (precipitation-hardened aluminium alloy, containing magnesium and silicon as its major alloying elements) - 6061 is about two bucks per pound [2]...

Using the weight calculator [1], and plugging in 23.5/23.5/141 (all in inches) I am getting about 7.7K lbs, or around $15K in material costs. Given it’s unusual shape, I’m assuming that normal is producing it. This would require additional costs for machining and processing Dash I’d probably say it would be several thousand dollars in additional costs. Overall this looks to me like a $25,000 piece of metal...

It's a valid concern, but please don't interpret the comment as snark. Speaking as an engineer, in absolute terms the competence of someone (or lack thereof) is clearly signalled with a setup like this. Perhaps it may have been better phrased in these terms.

Similarly, the second comment regarding what I believe many would agree are obvious social implications arising from a device like this could also have been better phrased. Isn't it also a rule on HN to treat all comments as being made in good faith where multiple interpretations exist? In any case I apologise for the phrasing, it was rather blunt and certainly somewhat off the point, but I also believe it captured important sentiments that would have been difficult to conjure with alternative phrasing.

I had a hard time getting to sleep last night because my own comment got me thinking that I need to choose a license for a project I’m working on, and WTFPL will be offputting. I know many projects offer dual licenses. But I’m thinking I’ll ask a (lawyer) friend and come up with enough CYA to protect myself, default to WTFPL, and let people choose their own adventure to whatever more restrictive license satisfies their legal department
Stripe is the ultimate purveyor of proverbial shovels in the SaaS economy. To me the question is, why do they need more investor money?

So much capital is flowing through their servers that it kind of shocks me they'd need to give up any more equity rather than raising or altering price structures for their users to hit their financial targets.

That's basically what they did when they made the switch from PPC to x86. IIRC, there was an edict a few years before the switch (Jobs talked about it in an interview at the time) where teams were told something along the lines of not making any design/optimization decisions that were tied to PPC. They likely did the same thing with x86 this time.

entropy is phenomenon of probability. It works because probability works.

People think entropy is some natural phenomenon in nature that is fundamental.

No. Entropy is a consequence of probability. The math works because probability happens to apply to nature. The below is the intuition behind why entropy occurs... once you will realize this it will make sense.

Disordered states tend to be more numerous then ordered states that's why any random configuration of gas particles in a system is more likely to be disordered.

Also when you try to purturb the state of random particles from state1 to state2, by probability state2 will be disordered because there are far more possible disordered states than ordered states... even when the initial state is ordered. Hence entropy increases.

The philosophical thing people should be examining is the nature of probability and reality which we already know is intrinsically tied with the nature of fundamental particles.

Probability is an axiom, entropy is a theorem derived from the axiom of probability.

In my experience the most difficult for us techies to lay down to somebody outside is the analogy. Is the make or break of entire explanation. And usually I fail 75% of the time right there at the start. Some recover later when I go with examples, but most of them are lost from beginning. Yeah, I know, I'd make a terrible teacher.
I'm caught between a couple of possible use cases:

* Perhaps this is similar to a potlatch or a peacock's tail: primarily a demonstration of social or genetic superiority. "If I can publicly waste resources on this sort of scale, imagine the sheer amount of pure nerd dominance I can summon!"

* A related use: Like clothing with an excessive number of pockets and ordinary household tools inexplicably machined from heavy steel and painted black, this is intended to convey the bearer's sheer tacticalness. In certain communities (those likely to append "-ops" to everything they do) this sort of thing can be extremely effective in establishing group membership and even invite grooming behaviour from strangers.

* "Hey, we all need to do our part to support global warming ... wait ... what do you mean we're against that?"
I was making more superficial points: (1) changing the subject to abortion already breaks the site guideline against generic flamewar tangents, and (2) a bomb-throwing word like 'genocide' is a flame multiplier that breaks the guidelines even further.

> go ask your fat friend about his last check-up

The doctor probably told him to lose weight. And?
> it's the health care that's so expensive

Doctors earn well but not particularly different from FAANG-style software salaries.

I don't know how good these numbers are but here's some:
https://blog.nomadhealth.com/complete-list-of-average-doctor...

For example emergency medicine doctor is listed at 366K average (~$162/hr). So when I've had to go to the emergency room and end up seeing the doctor for about 20 minutes, that's about $54 worth of doctor-time (as an order-of-magnitude approximation, ignoring fully-loaded employee costs since I don't have that number).

And yet the bill that arrives is on the order of ~$6000. Sure there's also nurse salary to pay for my visit and other legitimate overhead that's part of the actual "care".

So from that bill I got, over $5000 are inefficiencies and non-care-providing rentiers inflating the cost. Nearly all the bill goes to entities other than the actual medical care providers! So no, it's the the actual doctor+nurse salaries that makes the USA health care so exceptionally expensive.
I like all three of the novels in the series, but for dramatically different reasons and feelings.
> Tell us about your SaaS.

I'm a private guy. But I will say that it's a Greek startup, birthed in my English dorm room (Comp Sci grad; taught myself programming at age 11 by reverse engineering GORILLA.BAS; shout-out to all you DOS 6.22 babies #486dx2 #duneiichani #zerocool #snowcrash #bbs #qbasic #mode13h #nehe #0x5f3759df #lamp #vi).

> What were your challenges early on?

From a life standpoint, it would have to be student loans. But in crisis lies opportunity, because by working to pay these off, I programmed database integration layers between a bunch of local companies that ultimately led to a sweet SaaS system.

From a technical standpoint, there were many fun challenges, such as 2,000+ days of uptime with multi-master replication. But the biggest challenge was probably getting an early version of Quixote and a cranky SOAP protocol to talk to a bunch of SAP EDRs; that's when I learnt people skills.

> What were your hardships?

The usual stuff... paying the rent, feeding myself, no free time. It was all systems go back in the day, and dating wasn't really an option; but I'm thankful for lots of genuine friends, who welcomed my intermittent visits.

From a business standpoint, the biggest hardship was my constantly wrestling with the idea that I could do anything but I couldn't do everything. Once I concluded that exercise I found peace, and then everything else just clicked into place.

> And what were your lessons learned?

1. There are multiple SaaS strategies. One such strategy is to go super niche. Emphasis on super.
2. Going super niche doesn't scale, but it will allow you to prioritise free time - whilst living a steady, balanced lifestyle.
3. To go super niche, build your SaaS in such a way that you can run it from your mobile phone.
4. Always keep an eye on your phone, so that when the need for customer comms arises, it flows with elegant efficiency.
5. The quality of your communication with your customers is your competitive edge. Excel at this to justify your pricing.
6. Optimise all your business processes around minimising your phone's notifications - the goal is to maximise your free time.
7. At your leisure, routinely check in on your customers for a friendly catch-up. This enhances your competitive edge and bargaining power.
8. Always add value to your customers, and if you can't add value, walk away. You'd be surprised how much you can earn and still add value.
9. Enjoy time. Discover who you are. Explore life with your family and friends. Exercise your body and mind outdoors.
0. Help others. Volunteer your skills and resources. I advise several entities and it brings me great joy.

> What would you do differently?

Perhaps I'd have picked a name that was easier to recall, and easier to spell.

But when you go super niche, it doesn't really matter what name you pick.

> Also, prices aren't stationary

I'm not sure about the rest of your comment, but this is mathematically the correct reason why we don't predict absolute price levels.

And the reason why this is mathematically the correct reason is because for a non-stationary process, when you predict into the future, the variance tends to infinity which means taking expectation on any statistical model is useless since the variance is ridiculously wide

For me the ban on smoking in bars was a great leveler, smokers would have to go outside and hang out with people that are all in different groups inside and everyone would chat to each other.
