The problem of redis isn't speed of single object storage and retrieval.

We know for a fact that redis stores shit fast. And a blob of json is perfect.

The problem is multi-fold. Now you have a schema-on-read. You may spend a lot more processing time querying and accessing the data rather than getting exactly what you want from a sql query. Concurrency and locking. Constraints dbs offer.

So it is important to evaluate on more than JUST read/write speed.

I worked on a team that used nosql for their db needs. The performance was so terribly slow, not because of read/write speeds, but because of everything I listed above. They had to basically manually write a query optimizer vs sql. They quickly swapped to postgres and had somewhere along the lines of 10-100x performance (depending on what parts) improvements with only a week of work.

The CTO probably had a lions share in that. Not surprised how it went. :(
I'm of the impression that this is a misconception. 50 years ago, "programmer" was a different job. Imagine if executives were just called secretaries now and that's a decent analogy for what I think happened to programmers and architects.
1 year is pretty much the modern standard for the minimum appropriate time before moving on in my experience, so I think it's fine.
I usually hear this kind of statement, is it really that simple? Aren’t there other geopolitical interests from the strongest economy in the world?

That's a gimmick (defined as: An innovative or unusual mechanical contrivance; a gadget.) and hardly proof that dual screens aren't a gimmick . It sounds very creative and may have been well executed, but it's still a gimmick that won't make it into other games.

I played the hell out of my DS, but the second screen was mostly a crappy input mechanism.
Really well done! This is a very great idea and well executed

> Think about it this way, as a small-time investor, you won't always get the best price.

As a small-time investor, you can trivially get a better price than larger investors. And you must, by law, get the National Best Bid and Offer (NBBO) which is, at least for some purposes, the "best price".

The deck is heavily stacked against retail investors trying to actively invest, but the issue isn't being unable to get good execution!

Try not to take it personally. With relevant details not made clear, people have to try to fill in the blanks. Wondering about the table definition is definitely understandable.
Other cultures as in what? Far as I can tell, the best predictor of female participation in technical work is poverty. In rich countries with free women, engineering tends to sit around 90% male, and nursing tends to sit around 90% female.

The freer and richer women are, the more likely they are to be found in stereotypical fields.
[PM on Brex Cash here]

Thanks for the response, all great questions. Answers below:

> Can you guys elaborate on this in non-marketing/PR speak? If it looks like a duck and walks like a duck…

Brex Cash functions like a checking account, but the structure behind it is different. Traditional banks separate checking and savings accounts, which means customers earn a lower yield on their money as a whole. To be able to offer yield in all of the funds, we use a different structure: customers put their cash into Brex Treasury LLC, a registered broker-dealer affiliate of Brex Inc., that invests the cash in U.S. Treasuries through a money market fund. This means that while we don’t offer FDIC insurance, funds are held in low-risk securities backed by the U.S. government.

> Do we want you to be getting around the regulations? Are those regulations in place to hurt or help us (the business owners)?

Brex Cash is regulated as a broker-dealer, by FINRA. This is a well known structure used by Fidelity and other large financial institutions to offer similar products offering higher yield cash accounts.

> I’m genuinely curious here — I am seriously excited about a real, digital-first, intelligent, non-physical business bank. But I’m immediately concerned that you’re trying to “move fast and break things” and frankly I don’t really want that when it comes to my business checking account.

Totally understand the concern, and this is top of mind for us as well. We’ve spent over a year building the right technical, regulatory, and financial foundation to make sure we can scale this product. This is a product that we have built to be resilient and not to move fast and break things -- when it comes to customer’s money, we simply don’t do that. We’ve been working with customers for months to make sure the product functions well. Lastly, we’re rolling it out slowly, starting with an early access program for existing customers. Our motto internally is: “The Brex Cash rollout should be boring” :).
How do you know something isn't broken in production?
My natural tendencies are definitely in the libertarian/capitalist direction. I think that people should be able to whatever they damn well please with their money. I think that they will get it right more often than not and that when the government steps in to make laws restricting the free exchange of goods/services/money it's almost always a bad idea.

But I'm also a personal finance nerd, so eventually I found myself reading https://www.reddit.com/r/personalfinance/

And then I read different versions of the same story over and over and over again. People with far more credit card debt than they could ever pay off. More than a year's salary worth of debt. People that we just stupid about money, and bought way more stuff than they could afford encouraged all the way by the credit card companies and advertising and keeping up with the Joneses.

So now, from time to time, I sometimes find myself wondering if credit cards should just be illegal. Such thoughts are heresy in my own mind, and I don't know how to deal with them really especially because I know that credit cards have been great for me with my 2% cash back and airline points. And I know that they can be great for people who get into a temporary cash crunch and know how to be wise about such things.

But then I read another couple of pages of /r/personalfinance and I wonder again. Maybe people do need protecting from themselves. It certainly looks like some of the people posting there do.

I find myself very sympathetic to the author's views.
How do you prohibit making code better?

The Chinese Gigafactory cost $5B and should eventually produce 500,000 cars (less than 10,000 a week like its counterpart in US). If it takes 5 years to wear out, then Tesla would have to make ~$2k per car produced to pay the factory. I am curious to see how this Chinese factory would perform in the next 6 months. Clearly the plan has been to produce more per factory, and it did not happen yet. But I have faith in automation to eventually improve the factory's output.
I dunno, I find using relations I'm not supposed to modify pretty odd in an ORM. And YMMV, but I've never seen an updatable view in the wild. I know it's doable, particularly in Postgres, but it seems like something capital-S Surprising to...probably most folks I've ever worked with?
> The Taycan is $150k - it is not a mass market EV.

Ahh, I see - the line must be at $120k, right? Since I can order a $115k Tesla which is somehow mass market?
...until the people doing that learn to say "this is my step-son" instead of "this is my son".
That's a zero sum game. Let's consider two possibilities that aren't zero sum.

Late payments:
A credit card company might make slightly more money when people pay late than it costs them in servicing and default costs while the cost of the fees alone may exceed that benefit even ignoring the cost of a diminished credit score

Increasing spending and borrowing:
A company does marketing that convinces people to spend an amount (either through marketing a new card, a line increase or straight up marketing spend), that nets the issuer $100 in value and creates $30 a month in interest for the customer for six years.

The argument is the same as any other case of information asymmetries that create negative externalities. How should we regulate marketing cigarettes? How should we regulate marketing cotton candy? A purist would argue we ought to tax those activities.
You realise all stocks are priced based on predicted future earnings right?

People will give you all sorts of misinformed explanations. Matt Levine, the Bloomberg columnist, is a respected guy who understands the industry. Here's his take, a trustworthy take, on it: https://www.bloomberg.com/opinion/articles/2018-10-16/carl-i...

(skip forward to the part where it says "Robin Hood", it's just part of his column that day)

tl;dr You're not getting screwed by Robin Hood (as a matter of fact, they're good for you), but Robin Hood is enabling you to make trades you shouldn't be making in the first place because you're probably unsophisticated.
I'm sorry that I can't find the reference for this right now, but I read a paper a while back showing that (particularly stochastic) gradient descent usually finds good solutions (and that these solutions are very close to each other), although not absolute extrema, to highly dimensional neural networks. Whats more, you usually want to avoid finding absolute extrema solutions because they often suffer from overfitting behaviors.
It's a fair point, but this $28b is not for one person. There are probably hundreds of thousands of people working at Capital One. All of the profit is spread out amoungst them. (Not evenly, of course). Many of them are making a pretty average salary. So yes, for them it's just making a living.
"Also, twins boys have a significantly greater likelihood of homosexuality (less testosterone to go around)."

Is the theory that male homosexual=less testosterone really more accepted than male homosexual=more testosterone? I feel like the latter has been argued extensively.
I think you're pretty much completely on the right side of this and your other comments on this thread have been really strong, but this comment would be much stronger without the coda about downvoting, which (1) contravenes a guideline on the site and (2) really just invites spite voting.

I can't offer any advice to your situation beyond trying to avoid being discouraged. There's a balance to confidence; too much or too little can be offputting, and it seems like you're hitting a low point that might make things harder for yourself.

I would suggest not hanging yourself with your academic performance though. Some people work better with different methods of learning for example, and not all teachers recognize them, particularly if they learn differently - it doesn't necessarily make you dumber. In retrospect, you should ask yourself what specifically caused you to be a C average student.
I mean, you should be able to claim either if you have evidence. We should be looking for truth, not virtue signalling by withholding findings because it might hurt some people's feelings.

I’d argue the real problem is that Tesla puts this experimental buggy self-driving stuff out into the general public, knowing, because they’re not dumb, that ‘troubles’ are going to happen because of it. The big auto manufacturers don’t do this public beta testing with 2-ton behemoths because at their scale, the ‘troubles’ caused by that attitude Tesla has would be a national scandal with prison time.

Are we sure the PFOF money was as material as the commissions were? Are we sure PFOF is really how Robinhood makes their money? There are other weird side hustles that e.g. make Robinhood money based on how many of their users hold and trade meme stocks, for which they collect short lending fees.

I saw these during my 18 months at Google. They were never relevant to my work.

Working at Google you are bombarded with "nudges." The garbage cans have stop smoking signs. The plentiful candy is famously placed into jars to reduce consumption. There's signs telling you not to sit on the loo for too long. You'll get emails comparing your travel and server expenses to the average. All of this stuff is well-intentioned, but there's clearly part of the company seeking ways to manipulate its workforce.
of course picking to use a superoptimizer itself may not be optimal, and so it goes :)

At the end of the previous quarter Tesla had 4 billion in the bank, its highest ever. It also has a new factory in China that is about to go into production, and several new models that will be coming out. And its efficiencies of production keep improving.

People like you have been predicting every quarter for the last 10 years that Tesla was on the verge of going out of business, and yet it keeps going from one success to another.
That would have to be an incredibly precise test though; if someone is in denial and you tell them "This test says there's only a 5% chance you're right", they will probably stay in denial.
They make most of their money from interest on parked cash (they also offer managed portfolios and the like, but I've never felt the need).
Why should they be shocked that it doesn't work? Why is something that doesn't work and can kill people being deployed anyway? It doesn't work!

You cannot blame people who bought a car because it has a feature they want actually trying to use that feature.

Innovation! Are they selling order flow like Robinhood?
I agree. At least the authors are more modest about the findings than the headline:

> “[...] it’s important to note that the absence of evidence is not evidence of absence. We found that there is no evidence to support this effect of testosterone, but that doesn’t rule out any possible effects. From what we know, though, it seems that if testosterone does have an influence, the effect is complex, not linear. Reality is typically not that simple.”
> instead of the commonly cited argument of securing resources for the American empire).

I'm sorry but there are very few "citations" that state that the war was about securing resources for the American "empire". It was primarily about exactly the stated reasons and there is a popular and uncited belief that it was about oil. If you have some scholarly articles that state that it was completely about oil I'd love to see them.
> But I have faith in automation to eventually improve the factory's output.

Tesla's CapEx has been disappointingly low. Any kind of improved automation will require new equipment. Unless Tesla can scrape together more cash to improve their CapEx figures, its basically impossible for them to get "Better equipment".

IMO, Musk is spending too much money on unnecessary projects (ex: Cuphead ported to Tesla. Full-self driving custom designed chip. Etc. etc.) and not enough money on simple & boring stuff like better factory equipment.

I think the best way to convey something you don't know how to say is to put it this way

"I don't know the right words to use - so I'll say it directly. I BADLY want to keep this job but I even more so can't be 'on call'" .. you can explain to them that for you personally you need separation between work and personal life."
I don't know that I personally would use the adjective "ethical" to describe Schwab---that word can be taken so many different ways.

They are certainly a much better company to do business with than, say, Wells Fargo, and have largely avoided being completely terrible. Of course there was that nasty fiasco with the YieldPlus fund a few years ago...
I don't think it implies that at all. To me, having a shot means that it's entirely in the realm of probability.

"He breaks clear of the defender and has a shot at goal" doesn't imply "it's unlikely to happen", but there's a notable chance of it.
No. More like a FED sponsored 401k match for wages. If a company thinks it can earn more by producing more goods, it will hire more people and give them wages. The FED will match it, effectively bringing money into circulation.

As company gets more and more efficient, they wouldn't need employees. But this would cause lesser money to be brought into circulation, thus eating up the companies earnings itself.

If the company wants more debt, they can go borrow from others (rich institutions, individuals etc) but this activity will not create new money. Thus, total money in circulation remains the same.

If an individual wants to buy a house, the house price will effectively be closer to the median affordable income of population. Thus, it will incentivize individual to produce more goods and services to reach median income at least. The only way to become richer is to produce more.The rich can try to buy more houses but it wouldn't be possible as much since leverage and speculation is much harder.

And probably also a lot on short fees on the securities they lend out. Cheap brokers lend out the securities you own to short sellers, short sellers have to pay interest for such privilege (there's essentially an OTC market for the % rate). Note that this is not much different from earning interest on lending out cash.

Respectable brokers pass at least some of the short fees to the investor. Interactive Brokers, which I use, pays back around 50%.
Standing between Saudi Arabia and Iran was Saddam Hussein and his military. By removing him it created a power vacuum that has been filled by various groups over time.

The different election results in Iraq over the years now point to a chess game between Iran and Saudi Arabia for regional control.

Now instead of Iraq standing between the other two, it's serving as a way to create conflict where the two may eventually fight each other like the Iran-Iraq war in the 80s.

If the U.S. does not get involved in this scenario then the long term strategic outcome of the 2003 Iraq war might be seen differently. On the other hand, if Iran wins and becomes more powerful, the Iraq war will look even worse.
