Super interesting, thanks!

I’ve been doing zoom teleparties for a few weeks now and they’re really kind of magical. I started when I had to cancel one of my IRL dance parties and we thought we’d give it a go. As a meatspace party promoter and DJ i was really surprised at how successful these are, and how much of the real life party vibe translates. At our peak we had 160 or so zoom guests and you really felt that presence!

With the apps we have now social interactions are limited to chat and physical communication (lots of people will mirror folks’ movements, which is always a joy). There’s so much you can do.

I’ve got a ton of ideas and sketches for a real online party and event app — a kind of perfect blend of my UX life and my party life. I’d love to work on it if I could find some folks with web conferencing experience.

Nonlinear optimization algorithms.

At work I'm working on anomaly detection using ML at the edge and want to move beyond bog-standard stochastic gradient descent to fit the model(s) in favor of methods that exploit the use of analytical Jacobians / Hessians. So I'm comparing and contrasting the various nonlinear (gradient-based) optimization methods for my use cases and trying to see how fast I can make them run.

I mean, look at UPRO (3x levered bull S&P 500 ETF). From inception (2009) to date it's returned 1000% compared to the S&P 500's 170%. And from inception to Feb it's returned 3300%. I've personally held UPRO from 2014 until late January and have made a truckload of money off of it. I then made a truckload more money buying VIX futures before the VIX spiked to over 80. People say that you shouldn't hold these things long-term, but that's simply not true. All you're doing with leverage is increasing your beta. Obtaining 2x leverage on the S&P 500 is going to look pretty much the same as buying stocks in the S&P 500 with a beta of 2. Yet no one complains about high beta stocks being a scam.

You're telling me you would short UPRO? If you shorted UPRO pretty much anytime between 2009 and the beginning of 2020, you would have lost either all of your money, or in the best case, most of your money.

"These ETFs simply aim to match the relative daily returns of their respective index and occupy the bottom left spot on the aforementioned two dimensional spectrum. A closely related (albeit far less popular) type of product that occupies the bottom middle is the leveraged ETF. A leveraged ETF seeks to obtain a daily exposure on an underlying index scaled by a constant l; which, at this time, is somewhere between -3 and 3 for products currently on the market. If l is less than zero, the ETF provides short exposure to the index and are often called "bear" ETFs; conversely, if l is greater than zero, the ETF provides long exposure to the index, commonly referred to as "bull" ETFs. These securities are usually implemented by means of a rolling futures strategy."

"At face value, a retail investor might assume that if the S&P 500 returned 10% in a given year, a 3x leveraged ETF would return 30%. Fortunately or unfortunately depending on your perspective, this is not the case as the ETF seeks to maintain a 3x multiple on the daily return of the S&P 500 instead of the annualized return."

The post is about how the conventional wisdom behind these ETFs as "trading tools" is simply not true. All these ETFs do is to increase your beta exposure, in much the same way that buying high beta stocks increase your beta exposure. Practically speaking, there's little difference between a portfolio of stocks with an average beta of 2 and a 2x levered S&P 500 ETF. The risks are the same. Yet, no one goes around calling AMD (which has a beta of 2.83) a single day "trading tool." In fact, holding AMD is way riskier than holding a 3x S&P 500 ETF!
So what about Mary, Sue, Becky and the dozens of other owners of Home Stores. All of them can’t hope to be discovered via organic search.

There's no way to win selling cheap but critical supplies on the spot market. If the price goes down your customers flee. If the price goes up you can't charge the higher price because that would be "gouging".

So his solution is contracts. The fact that people aren't signing them shows their true intentions.

Try to take a ~30 minute nap in the evening somewhere that is quiet and comfortable but not the bed you sleep in. 4 hours isn't sustainable for long, but I've found a nap in the evening is sufficient to let me run effectively on 5-6 hours.

I say somewhere that isn't your bed because I've found that if you settle in the bed it can be far more difficult to get moving again, and also you can start to associate the bed with naps and have more difficulty getting to sleep when you mean to later, and staying asleep.

The central point of your comment was false and invented. You have claimed they made assertions they absolutely never made.

I don't see how the TLS claim is relevant, your comment is still wrong. It also misrepresents their argument, that competitors using cloud backup is less secure than not doing so because it introduces a very untrusted third party (Google Drive is not E2EE).

Their claim that E2EE + Google Drive backup is not secure seems pretty valid to me, not that it's related to the inaccuracy of your comment (it's still a false statement, and pretty egregious considering it's never been claimed).

Why are you putting words in their mouth?
Additionally your initial post implied that this is what you think, because this is what you study for interviews.

Thousands of people study about how to reverse a binary tree on a whiteboard and other needless leetCode to “work at a FAANG” even though they don’t do that everyday.

What you study for an interview is unfortunately often only vaguely correlated with what you do on a job.
Interesting problem. It would be partly solved by the look-and-look-back protocol, because then it's obvious that you are speaking to a single person. But then, it could still happen that you accidentally avert your gaze and drop back to the common chatroom, making what you are saying audible to everyone.

I had written a Python script to get saved (upvoted) links as JSON / CSV a few years ago: https://github.com/amjd/HN-Saved-Links-Export

I'm not sure if it still works as it too relied on HTML scraping. Perhaps I should update it to support favorites too.

Edit: Whoa, it's been 4 years already. I believe HN didn't have favorite feature at the time. That's why I used upvoting as my bookmarks system and created a script to export that data.
Thanks for the detailed reply. I agree with your comments regarding data quality, I assumed you had an issue with the methodology. I just took this paper to be a heuristic that could help inform decisions with the limited data we have so far, and not as a definitive answer.

> Hold them long enough and you will give back gains and most of your capital to the house.

How, why? Everyone says this (which is why I wrote my post), but no one has actually explained it to me. A leveraged SPY ETF does not have a high carry cost. Sure, if there's an ETF that's buying long-dated contango futures, then yeah, you're going to lose money in most environments (TVIX, etc). But leveraged equity ETFs do not have this property. Moreover, if you really think that most of your money is going to go to the house with any of these products, surely you should just be able to short all of them and make a risk-free profit, right?

Nothing quite like being able to arbitrarily write “randombusinessname@mydomain.com” on a form and be confident it will work, all for $50/yr.

It’s good to set up and host email for awhile to more deeply understand how it works, but do it for a domain you don’t plan to use for important emails. Then, when you’re sick of it, add that domain to your Fastmail or other hosted account with a deeper appreciation for what the modest annual fee is buying.
This is hecka cool. What a clever concept! I like the idea of piggy-backing on top of a mechanism that is sort of kept in the right state by consensus.
Completely disagree here — that's how you get extreme program bloat.

Lets take this scenario. I want current weather value be part of config value. This could be pulled/scraped from online source in 2 lines of python.
Alternative as you imply every program should have some complex abstraction for scraping now? That's just silly.
The article here is about how the media can often help spread misinformation, which can be really bad in a pandemic, so going to guess that's what they're concerned about.
The leveraged ETFs have a few extra footguns, don't they? Did you see that Direxion suddenly changed the ratios on a bunch of 3x down to 2x on March 31? Scary stuff to me.

In 2009 a leveraged ETF trading at $100 ended up paying about $85 as a dividend (I think because it was excess profit by being long vol.) That would be an overnight tax hit if you are in the wrong type of account. I don't recall which one it was, maybe FAZ?
Very good explanation of the current state of the art in STT. I have also personally gone down this rabbit hole(especially the CTC bit) and agree 100% with what the author says. My personal viewpoints:

1. To have an ImageNet moment, we should have an ImageNet. LibriSpeech doesn't cut it. We should have an equivalent SpeechNet. Problem is visual language is one, while speech languages are many. So we should have an ImageNet for every language? And train for every language?

2. What is an ImageNet moment? Personally, though ImageNet has contributed a lot, similar to speech and NLP, even vision applications have promised more and delivered less in real world scenarios. And just like speech and NLP, only the big boys actually provide solutions in vision which shows in vision also they have access to better data which they don't share.
> 100 year contracts with strict non compete clauses and defined rules around sourcing / pricing and failures to comply.

Exactly. IIRC Sysco negotiates 50-99 year contracts with e.g. universities to supply on campus dining. It seems that firms in the healthcare supply chain would do the same.

My bar for evil is a lot higher than "signed exclusive distribution agreements with some OEMs in the 90s."

Illegal? Sure. Evil? So some other millionaires didn't get to become billionaires. Meanwhile the world got a single API to write software against for almost two decades, how many ISVs existed because Microsoft provided an insanely stable (in regards to API churn) platform to develop against?

Hell right now with 2 major mobile OS players there is a huge tax on developers, imagine if the 90s had been a wild west and there had been 4 or 5 major players.

One can also note that given how mobile played out, there is a good chance that the desktop market would have coalesced around a single dominant OS and a secondary minor OS anyway.

And yeah I know everyone is pissed about BeOS, but they also had their chance to be a player until they tried to hard bargain with Apple and Apple walked away!

Selection bias?

If you don't control who gets the treatment, who gets a placebo, and who gets the current state of the art treatment, you cannot really exclude your results are biased. There are some ideas about how to reason with observational data but your conclusion are still weaker as with experimental data.
It should still be a perf gain:

1. Memory allocation isn't free
2. Doing multiple loops over the buffer (once per operation) is going to be slower than doing all the operations at once, both because of caching and the opportunity to do the operations on a register and write at the end (though who knows if the python interpreter will do that).
Overall I agree but I take issue with the Twitter smear.

People who were on Twitter saw this coming weeks ahead of everyone else. There is a reason Twitter the company (and square) went full remote before anyone else did and that reason is that there is data on Twitter that is immensely useful (yes there are trolls and fear mongering too) Twitter outperformed our CDC, the WHO and many others in terms of 1. Sounding the alarm 2. Promoting solutions 3. Challenging erroneous solutions/stories championed by our leaders (eg “we stopped this”) and institutions (eg “face masks don’t help”) AND it did this a full 2 weeks BEFORE mainstream media.

It continues to be a much better source of information than the vast majority of traditional media (and quite a bit better than WashPo IMO, lost a bit of respect for Cal on that one, still respect him a lot though)

Twitter can be just has “heartwarming” as other mediums and other mediums can be just as toxic. Follow smartly.

All the other mediums are based on “look at me” Twitter is based on “look at this”, its not social media. It is vital and useful news. What you will hear filtered through a biased secondary source next week on CNN/Fox (or in 2 weeks via a tertiary source on FB) you can see live on Twitter now.

At least these days, it's not so easy for a journalist to have a career ending mistake. My example for this is Daniel Lyons, for whom I have practically no respect at all as a journalist. His participation in the SCO debacle should legitimately have been career ending (and IMHO was not at all mitigated by his subsequent apology). His "Fake Steve Jobs" work breathtakingly poor judgement, again IMHO. I mean there is trash journalism and then there is making stuff up and hinting that maybe you know more than others do (all the while saying, "It's just a parody"). Let's not even talk about bit that's mentioned at the end of his Wikipedia article (I really hope that's not true!). But let's face it, he's a talented writer. He writes engagingly on topics that are interesting for a lot a people. The fact that he exercises absolutely no judgement whatsoever in his research is unfortunate, but even this is appealing to a lot of people who want to believe what he writes. I suspect that there are more people on HN who love him than hate him. How would you filter this kind of writing without some draconian censor forbidding him from publishing?
Cut him some slack. He's got like 20 jobs.

Trying to figure out how to teach myself EE.

It looks like theres basically two suggestions:

A) Following the same sort of curriculum a university would teach. I'd have to manage to dredge through the math, but I suppose it's possible but would lead to probably the most competence. Unfortunately however, I was hoping for the big MOOC sites to have more content. EdX has some decent introductory stuff but not much beyond that.

B) The other recommended way is the hobbyist way and what I suspect most other software people wouldnauggest which is just building shit that interests you, ignoring first principles. Unfortunately I'm not sure how this would work out, since my projects in any domain seem to be a bit, er, grand and you supposedly need a strong math background to build anything more than basic circuits.

I'd dread the math a lot less if it were more cut and dry. I wish I could just jump right to calc, differential equations, linear algebra, etc. But more realistically, it would involve me hunt and picking parts of algebra and embarrassingly even simpler stuff. I was looking at some Khan academy stuff and while it turns out I remember more than I thought, theres still plenty I had forgot even existed.

Another alternative that seems good, but not realistic is that there are some community colleges that have professional certificates that teach electronic circuits pretty quickly. Unfortunately this is prohibited by the absolutely fucked "residency requirements" for this state whereby I wont be a resident of my current state for years (at least for tuition purposes, I'm a resident for just about everything in a few months). Also those courses are all in person which, for some unique reasons dont fit my life situation.

Perhaps I misunderstand it as one person commented but the part that creeps me out was this one part (iii) the pages of the Site a user visits; and (iv) other sites a user visited before visiting our Site.

So they not only track what you do on their site but will be tracking the rest of my internet browsing history or am I misunderstanding this? There was more I didn't like to be honest but I am on my way to bed so will leave it at this point for tonight. This is my kids privacy I worry about they don't know how to and if I have to use a service for their school because of covid I don't want my kids and my internet browsing habits known. Other then a basic cookie for log in purposes there is no need to be doing a bunch of tracking on kids personal computers on there personal home networks. And since this is HN we have all see the many articles that basically say yes most of the time anonymous data can be tied to you. Yes I am sure it is so mundane to most but I really wish we had the privacy laws like gdpr because I really do not think our kids deserve to be snooped on. I appreciate your thoughts.
