Hi HN,

We're Abhishek and Rahul, building FinHawk, an automated crypto trading assistant. I had been a semi pro equity trader for several years and with no academic background in Finance, had to learn everything I know about trading and investing myself. Another major problem for me had been that it was difficult to discover and track trading opportunities, owing to the limited time I could take out daily after my regular job.

I spoke to other traders in my peer group who had been facing similar problems, who also connected me to other traders in their network including folks who trade crypto. Based on discussion with close to 200 traders we built this prototype (https://finhawk.app) consisting of the most commonly requested features.

Currently it is integrated with four exchanges - Coinbase Pro, Binance, CoinDCX and Unocoin, supports text commands like, "Buy 0.1 eth when rsi goes above 30" as well as a few other useful functions for traders. We're iterating based on feedback from our active users and would love for everyone at HN to contribute through their feedback as well.

In the long run the assistant will guide the trader through creating the strategy using best practices, add voice support and automate as much of trading workflows as technically feasible.

One of the points brought up in the article that I think is becoming pernicious is dicrediting by association. Any view that is also positively regarded by an extremist group (right or left) becomes evidence of the author's support for that group, even though there is no connection between the two. That's kind of like saying Apple must have created iPhones for criminals because they're preferred by drug dealers for their privacy! It would be nice if ideas could be judged on their own merit, not by who likes them.

Yes. Though ideally, we would redefine temperature units so we could get rid of R and Avogadro's constant in that formula.

Ie so that it becomes T := N / (p * V) where N is measured in number of molecules, not in number of moles.

So we'd measure temperature in Joule (or electron-volt) per degree of freedom.
That isn't more readable. It's non-standard. It also looks like a function call, but doesn't behave like one (in a function call, a, b, and c would all be evaluated). It's going to confuse other C programmers.

As Liquid_Fire points out, it's also probably incorrect.

A massive portion of Amazon’s value in the early years were product reviews. To this day they are proud of pioneering this aspect of e-commerce. I remember using Amazon reviews in the 90s and 2000s even to weigh what I bought at bricks and mortar stores. It’s the same reason that sites like Yelp exist.

Perhaps most of the reason they were honest early on was Amazon’s product selection early on was only books and media, and secondly there was a community where you could look at other people’s review history to determine if they were a shill and report it. That “community helpfulness” was common in early online communities. I’d say the majority of reviews were real through the mid-aughts.

It was only after the Amazon marketplace became indistinguishable from the main site that the scale of sellers flipped the incentive structure towards cheating.

Yep, I spent many years at a large, public US mobile game company and it was the same. We had a considerable number of players who had total spend in the 5-figure range, and a few into the 6's. And that's on one single game.

The constant rationalization around the office was basically something like: "They're paying for fun, it would otherwise be drinks/movies/real gambling/etc, we're just a different medium". This, of course, completely ignored the boatload of psychological exploitation tricks that we used to keep people playing (and paying). The game mechanics were literally a rigged slot machine. The meta-game was designed to constantly tantalize you with something just out of reach. The monetization was high-pressure, time-sensitive, and used false discounts to increase value ("Get this $20.00 pack for $1.99! Only for the next 60 minutes!")

It got very draining after a while, and I'm much happier now that I've left the industry.
It survives pretty well. I built a super basic localStorage only web app and it's worked really well. Until I switched phones and realized I didn't add export functionality.
Testing with only one if statement is not convincing at all.

I'm pretty sure that once you have a couple of mixes and steps etc., the branch prediction becomes exponentially harder and you are better off with the one line mixes, step, clamps etc. In general, from experience writing a lot of shaders, I want to avoid if statements, function calls and most importantly loops.

Now maybe if statements are efficient in some conditions, but if you want to add new details to the same shader some months later, you can't be sure the generated instructions and branch prediction will be as efficient.

There is also coding style: Id rather stick to a bunch of mixes, steps and clamps than a salad of mixes, steps and clamps with some multiline if statements in between.
... which is equivalent to a ternary, hence the thesis.

Not as common as I presume they are in Sweden - nowadays most job contracts for individual contributors without significant seniority or additional duties fall short of that (~6k gross or around 8k cost for employer), although with covid they are seen more frequently.

Great example of how language is a tool for thinking, but it's also a tool for not thinking. If you want to ignore or obfuscate something, you can seal it off with euphemisms and misrepresentations, kind of like putting an interface in front of an implementation. And as you pointed out, you can use this tactic to deceive not only others but also yourself.

Thanks for the insight! It's probably like everything else: make your proof-of-concept (full refresh) work, and refine the rest until you're sufficiently bothered to fix the full-refresh thing :D

As a plus, this is likely the most portable way of driving these, voltage levels notwithstanding. I guess you also have "smart" and "dumb" screens, some that include temperature sensors, etc?
The other component is that algorithmic feeds encourage echo chambers. People engage with outrage most when they are on the “same side” of it.

This comment is as equally polarizing as GP, just in the opposite direction. You can have social media be tech, have some net effect on society (whether that's good or bad is literally being debated right now) and be addictive.

As with anything in life, there is nuance. Social media isn't a great satan and it isn't god's gift, it's somewhere in between.
People have a need to be part of a tribe, and sports is a healthy way to do that opposed to

Different people get different things out of it. Some people were involved in sports as youths or still play pickup basketball or soccer and that adds to the appreciation of the pro sport. Gambling on sports was huge even before they started to legalize it.
There is a lot of insight in the description of all the individual, small- and medium-scale Chinese businesses in the region, and the article is well worth reading for this reason.

However, extrapolating these observations alone is not enough to explain the emergence of a relatively closely-knit elite of powerful business moguls who have a finger in every pie and can apparently do no wrong in their respective geographic areas of operation, while seemingly being unable to capitalize on the same business acumen to successfully expand beyond the region, a question the article also brings up:

To anyone interested in some good answers to the above question, along with an extensive background discussion, I heartily recommend the book "Asian Godfathers: Money and Power in Hong Kong and Southeast Asia" by Joe Studwell, a well-researched study of the topic that is also captivating to read:

I left the bay area for good after being burned repeatedly by folks whose social and moral beliefs aligned most closely with SSC’s grey tribe definition (as originally posted, not the summary from this article). While no doubt “not all Silicon Valley residents” applies, certainly after fifteen years of primacy of such beliefs my social circles, I’m sick of the grey tribe and will avoid living anywhere with a loud presence of it again.

(Note, I'm Head of Developer Relations for Streamlit, so clearly not a non-biased observer!)

You're absolutely right that Streamlit isn't a Jupyter replacement (we're not trying to be!), in the same way that Spyder isn't a "replacement" for the JetBrains set of IDEs. Maybe Streamlit will one day move to multiple language support, but for now, we're trying to be the best Python library we can be for creating web apps.

As far as GPU-support goes, as mentioned above, Streamlit "supports" GPU in as much as Python does. It's important to separate out front-end/UI from backend. If something is supported with GPU as a backend, "data science" (however defined) functionality, Streamlit supports that in the same way a React app calling a GPU API endpoint or other workflow is "GPU-enabled"
Buying on Amazon is becoming a real roll-of-the-dice. Last week I wanted to buy refill cord for my string trimmer (weed whacker, in local parlance). Listed among the third-party options was this apparently OEM part:

https://www.amazon.com/dp/B015T96KLO/

Many reviews say they received a knock off. I ordered from Home Depot instead. I don’t intend to use this right away and don’t want to be bitten later.

I reported this listing to Amazon, but it is still up. I assume this just isn’t a priority for them.

I have the same problem. Since Macbook pro 15"/16" run the dGPU 10-20W at idle whenever an external monitor is connected, which thermally throttles the CPU, I have to ration my external monitor usage throughout the day. So now my USB cable/port (I hope it's the cable!) is worn down and the connection arbitrarily drops when plugged in.

SuperSpike: Supervised learning in multi-layer spiking neural networks (2017)
Hi HN!

I recently made this auto reply app for WhatsApp with a focus on moving away from it. Many are having a hard time convincing friends and family to move away from WhatsApp and I hope this tool helps with that.

It basically just auto replies to all WhatsApp messages with the message you set. Just enable it and set a message something like "Hey I am not using WhatsApp anymore. Please switch to Signal" and it takes care of the rest.

- Simple: Set the message and it auto replies to all WhatsApp messages
- Option to Auto reply to group chats
- Respects your privacy
- No analytics or tracking
- Does not connect to Internet
- Free an open source (GPL)

Future improvements (just a couple weeks away):
- Option to set reply frequency: For example users can set reply frequency to 1 day and it only replies once a day for each person/group.
- Support for auto replying Facebook messenger

Please let me know what you think!
It’s really entertaining to watch Hacker News devolve and eat itself. It’s like contextual complex and nuanced thinking is impossible among those that self select as hackers. Have we gotten to the point where we can’t hold two opposing views of the same thing in the mind? Absolutism abounds here and while I’d say it is disquieting it’s more so simply sad. Sad in that it’s consistent across all facets of society. We’ve lost our critical thinking skills.
> when will you consider the possibility you may have been wrong? At $100k? At $1M?

Personally I think Bitcoin has at least two bubbles left before it pops permanently. So $1M price could be achievable.

The real question is what happens when it does reach a ceiling. At some point there's not going to much more potential interest for Bitcoin, and what then? Are people gonna start moving their pension funds to Bitcoin? I think the governments will crack hard down on that, because you really want investments in building the economy, not in a pure investment/gambling scheme.

If most people start thinking there's no one else interested in buying their Bitcoin down the line, it'll crash hard, and the crash will likely be permanent. Because there's no real value behind Bitcoin. The money you invested is already spent by someone on something else.

The reason why it's interesting that Bitcoin keeps having bubbles is that there's not much reason to think that will stop. Yeah, the value keeps growing over longer time periods, but eventually a bubble will be so large that it'll seriously disrupt the economy, and that's when you'll start to see governments and peoples attitudes change.

> I enjoy reading comments about Bitcoin here because even without any venture backing, it achieved a bigger valuation than all of the Y Combinator companies COMBINED, yet people still think it is unstable and has no future.

The problem is that the valuation is more imaginary than the valuation of any company except for those that are just Ponzi-schemes.

Most money put into Bitcoin has been cashed out or used for mining expenses. If everyone tried to cash out, the price would very quickly race back down to zero. If the same happened with a stocks in a corporation, at some price level someone would just buy up a controlling stake of the shares and liquidate all the assets for a profit.
Well, yes. How SBCL uses the type annotations as well as type inferencing to completely eliminate type checking throughout sections of code and generating highly efficient assembly code makes looking at the assembly output of SBCL especially interesting to look at. It gives you good feedback whether your type annotations had the desired optimization outcomes. I didn't want to indicate that other Lisp implementations wouldn't offer native compilation or a disassemble function.
I am reminded of comedian Ronny Chieng's bit about Caishen, the Taoist "God of Money". And how the New Year's greeting is literally "Hope You Get Rich" ;)

This is a great read. But the underlying fundamentals don't seem to vary much, East or West. Learn by doing. Trust your gut. Bias toward action. Cash is king.

>>> what separates the Robert Kuoks, the Mochtar Riadys, the Ng Teng Fongs and the Yeoh Tiong Lays from the rest of the traditional Chinese businessmen who have graced both sides of the Malaccan Straits? The obvious answer — the one that springs to our lips — is Luck.

Could you shed some light on what is wrong with being a monarchist? I mean there are still a lot of countries on the World that are monarchies: Sweden, UK, Norway, the Netherlands, Denmark, Belgium to name a few largest European monarchies.

Some of the founders of BLM call themselves Marxist. They partner with pro-communist Chinese groups. And the organisation's platform has a Marxist history. The Black Panthers published a 10-point plan in 1966 which promoted a new form of racial Marxism, which was largely adopted by BLM and was posted as part of their syllabus on their website. They quietly toned it down a few months ago so it's not quite so obvious now.

There was also almost certainly trade between the New and Old World by way of the Norse settlements in Greenland and Iceland, which knew about the North American mainland, and very likely visited the Labrador region for lumber.

The short-lived Norse colony built in L'Ance aux Meadows, Newfoundland in 1000 AD had an iron forge [1], which would have produced items in high demand among the indigenous people of that region. It seems unlikely that there wouldn't have been sustained trade once demand for these types of items had been established.

I'm against just heaving that technology out over the fence into the hands of consumers and leaving it up to consumer reports and/or individual consumers to decide if it's safe enough.

Safety is a 'picking up nickels off of railway tracks" problem. A thing might work 10,000 times in a row, but then suddenly, catastrophically fail because something is different that hadn't been tested before, like dealing with a woman walking her bike across a multi-lane road.

this is not a good scenario to leave up to consumers to decide whether a thing is safe. Not even with consumer reports to help out with testing.

Now as to ABS, the comparison is not even close. I do not buy ABS by purchasing brakes and then flashing some ROM with code I download from the internet. ABS is covered by all sorts of regulatory frameworks around the world, it isn't simply cooked up and offerred for download like it's an MP3 player skin.

Even though it's a much more mature technology, the problem with ABS is again, consumers cannot give informed consent to a disclaimer when purchasing it from some random person.

When I buy it as part of an automobile from a manufacturer that complies (I'm looking at you, VW) with regulations, I'm consenting to trusting something in a completely different way than when I download code and there's an MIT license or whatever weasel-wording somebody em ploys to say, "If you die, sucks to be you. If you kill someone, it's your soul that will be in torment."

Your equivocation of 1. downloading code for a safety feature from the internet that's marked "alpha" and has been tested according to whatever the author feels like testing because it's not offered as a "product," with 2. purchasing an automobile that has ABS brakes which are tested and maintained within a global safety regulatory framework...

You're entitled to whatever workdview you like, but on this pointI believe our discussion ends. There is a fundamental axiomatic belief I hold that is not compatibvle with a fiundamental axiomatic belief you hold.

I don't want to spend all day trying to explain why I believe Volvo selling a three-point harness is not the same as some random person knitting a seta -belt, selling it on etsy, and leaving it up to you and I to read the consumer reviews to decide whether it's safe enough.

You believe the free market plus informed consumers will sort all this out. I do not.
