Alright, well there's at least one that uses KDB. Agreed on C++ over C, but given that we're talking to someone that's calling themselves a 'technologist' thought I would recommend the best book to get started.
I've had a lot of people on Hacker News very confidently tell me that I have no idea what I'm talking about on this topic. For a long time I thought I was just dumb, but still employed years later and have realized that most of the people that 'correct' me have exactly 0 experience.
Hey I’m sorry, I’m not telling you you don’t know what you’re talking about. I do know what I’m talking about, it’s my field, I was just pointing out that often people mix quant and HFT which have different needs. Julia and KDB and Q tend to be more about statistical arbitrage or risk neutral pricing based model trading or whatever. They’re definitely widely used in funds, and a lot of traditional HFT have branches out from traditional HFT to include fast statarb and other things to juice margins and find a place for capital investment, so I wouldn’t be surprised if many of these shops use these tools somewhere but they’re not using Julia say in the kernel of the traditional HFT strategy.
I think if you feel like that’s happening to you the best strategy is to ignore it, but the second best is to prove your understanding. Explain with depth that can only be gotten from direct experience. If you know you know, either be confident in that or demonstrate it. I didn’t feel like you didn’t know what you were talking about though, I just thought you might be missing some nuance on the topic.
I think you raise good points. Please consider whether your comment would be better if it looked something like: "I know of at least one which does. I have relevant professional experience in this regard. I agree re C++, I thought these were the best books to get started, given they described themselves as a technologist."
(From someone who also gets defensive in online comments. I don't think they per say told you that you were wrong, but rather described their experience in relation to what you'd said. It seemed to me like commentary more than criticism. I don't have a crystal ball to tell me when people are exaggerating their credentials on the internet but they seem to be credibly claiming experience in this thread.)
This thread is why y'all need to focus on engineering and leave finance to professionals. Banks have assets (mostly bonds) and liabilities (mostly deposits).
Both of these items have a duration. They have to match the duration between their assets and their liabilities or they end up insolvent. If enough of the depositors try to pull their money out of the bank, then that reduces the duration of the banks liabilities, and the bank won't be able to move quickly enough to sell their assets to stay solvent.
The tech companies that are complaining about FDIC intervention caused their own problems because they are panicked morons.
Even more ridiculous is any one of these mega tech firms could probably step in and solve this situation with a cash infusion. They would almost certainly come out ahead because they would be buying a claim on the bank's assets for less than they are worth. But they won't. Because they don't know what they're doing.
What happened here is no different than what has happened in every banking crisis pre-08. The economy will be fine, someone like Berkshire Hathaway will make a stupid amount of money and customers will blame a bank for a problem that they created by being stupid.
The efficient markets hypothesis does not, and has not, stood up to empirical research since it was first invented. The reason that it's a hypothesis, and not a theory, is that it's impossible to disprove because all of evidence that disagrees with it is dismissed as spurious.
> he efficient markets hypothesis does not, and has not, stood up to empirical research since it was first invented
Yes it has. In its weak form.
More pointedly all the supposed counter examples turn out to be snake oil. People really want to believe there is some magic that can predict the future....
> the reason that it's a hypothesis, and not a theory, is that it's impossible to disprove
It is an hypothesis. It is impossible to prove it, only disprove it. And....
> because all of evidence that disagrees with it is dismissed as spurious.
All the counter examples turn out to be snake oil. I spend years looking, repeating simulations, back testing algorithms.... Snake oil each and every time
Momentum, value, and size are all predictive of future excess returns. If the weak form were true this would not be the case. And those are just dead simple buy-and-hold strategies that anyone can implement.
Society was told for thousands of years that astrology could predict the future and we believed it. But turns out, it couldn't.
Society was told for decades that "technical analysis" couldn't work because any advantage would be arbitraged away. Turns out, that was a bunch of BS and we now have very strong evidence for the basis of "technical analysis", momentum, going all the way back to the advent of financial markets.
This is a great way to end up in a situation where you have to re-write entire modules whenever you need to update old code... which is kinda where our teams tend to end up anyway so I guess it's not _that_ awful?
Google has gotten to the point where it creeps me out. I've switched away from Chrome. I don't use their search engine unless I can't find the results on Bing or DuckDuckGo.
I don't know if it's going to get to the point where it hurts their business (I'm just one person), but I'm to the point that targeted advertising is a really good way to make me not want to buy a product.
I second this. Try DuckDuckGo + FastMail and (Safari + Wipr extension for an advertisement free WWW)
I too switched away after being a lifetime Google Advocate: Android, Chromebook, GCP, Linux + Chrome and many, many of their products. Honestly, I don't care about privacy that much I'm just sick and tired of how good Google became at distracting me! Never mind the ads and how I had to use incognito search for anything because if I searched something (e.g. buying a monitor) google keeps suggesting similar stuff to get my attention or suggesting articles on the homepage of Chrome (mostly android).
What was once a simple beautiful tool to find answers, fast. became part of every aspect of my life, trying to get more and more of my attention/time.
Time is gold. Google lost respect for my time and I lost respect for Google.
Agreed, and a quick shout to migadu.com for email. I’m a long time happy Fastmail customer but Migadu’s offering is interesting and different enough to have a look at.
> They offer a lot for a low price, but I wonder how?
They don't respond to queries or requests. I presume that's how. To avoid repeating my comments too many times, let me suggest looking at my other comments on this post.
That’s good to hear. But I haven’t had the luck to hear back from them. So my guess is still that it’s a tiny team with many other priorities than this platform, and so misses responding or acting many a times.
