IMO the "problem" is that RH doesn't tell you that (or at least their marketing makes it confusing at minimum). The way they describe it as an "instant bank transfer", not "we give you margin until your transfer clears". The former gives you the impression that its your money that you're trading with, while the reality is it's a margin account.

That's why a lot of people were angry. They were forced to sell GME because they were technically using margin and it got called, but they thought it was their own money from their own bank account. The optics are that RH forced them to sell GME when they didn't want to.

It is the frameworks that give more rigidity and boilerplate, not so much those languages themselves (although Java does have more boilerplate than Ruby). You have a lot of freedom when you program in plain Java and Ruby vs. using frameworks in those languages. And that is at least partly by design. See the Template Method design pattern, which is the basis of frameworks that use Inversion of Control (IoC).
Ye. The belief in the "invisible hand" is strong. Boards and executives are not more rational than employees in general. Why would they not do things because they e.g. feel good about it or want revenge - like they were some super human well oiled machine.
Yeah, Arabic too. My bad. I was thinking about Greeks, and Khwarizmi wrote his algebra book al-jibr in medieval times circa AD 700 or 800. So I assumed that Arabic carried the heritage of Greeks before the Renaissance.
Did not know that, still the QC of their work and overall integration of services seems world-beating to me. I had never seen anything like it.

Their UX documents and implementation are for my money some of the finest in the industry.
Melvin Capital claimed they exited all short positions, yet there weren’t any significant change in short %. By all accounts, they had huge percentage of shorts, so them covering shorts should have dropped short % down below 100%.

It sounded too much like a PR move to convince WSB that short squeeze was over. Would Melvin Capital lie about short positions to save $billions of dollars?

Melvin Capital initially claimed their short losses were 30%, now they are claiming short losses over 50%. How are they still losing money on shorts?

I was not aware of that. Maybe it adds to the issue. This situation started before covid.
While this is likely true in many cases I'm in a very sensitive industry (banking) and we tend to self host things not for cost reasons but for security reasons. We spend a lot of time going through pen tests, getting SOC2 compliance, etc.

Handing off something this critical can cause an even more painful audit in many cases so just a thought to consider cost is sometimes not the only factor.

Looks like a really cool product though!

This is a portion of a message sent to all users that IB sent out Friday afternoon:

We are seeing unprecedented volatility in GME, AMC, BB, EXPR, KOSS and a small number of other U.S. securities that has forced us reduce the leverage previously offered to these securities and, in certain instances, limit trading to risk reducing transactions. IBKR currently has no restrictions on trading shares in those companies, and customers can open or close positions in those shares. Like many other brokers, IBKR placed options on certain of those stocks in closing only earlier this week. The plan is to lift those restrictions in an orderly manner while closely monitoring market conditions. To be clear, IBKR has not restricted clients’ ability to close existing positions in any of the U.S. securities subject to market volatility, and does not plan to do so.

The limits IBKR has placed have applied to all customers and were not limited to “retail clients” or any other group.

> Federation implies decentralization.

No it doesn’t. Gmail is a centralized instance of a federated network.

You can have a federated node that becomes so popular that it’s basically centralized.

This federated/decentralized distinction is pretty common.

You’re dwelling on literal definitions but there are more semantic differences those words have picked up in the communities involved.
TBH, that, for me, is the real scandal here. We have such an antiquated system that we can't actually be confident who owns the stock at any point until you do some super-slow settlement process that takes two days.

I think you must mean that covered calls or the wheel are less lucrative than more complex strategies, unless I'm really missing something. Can't get much simpler than a CC.

The Wheel as a strategy doesn't scale well, though. A good stock for the wheel has relatively low volatility, but with high volume of option interest. These two things are kind of opposed to each other, though. If a stock isn't very volatile, then there isn't much need for large option interest.

Of course there is a lot of overlap where things get interesting.

I think the reason why there aren't a lot of institutions running the wheel et. large. is because it just can't work at the scale they want to operate on. You can probably run the wheel pretty successfully at a million in capital (much larger than I'm used to), but at 10, 100, or 1 billion, it just doesn't work.

And what are they going to do? Pay some guy 200K to generate maybe 200K on a million in capital?

We're actually in the process of getting SOC2 and pen tests ourselves - another benefit of a hosted offering is it can (eventually) integrate into your compliance system (e.g., vanta)

A lot of our customers are in fintech (payroll, banking, etc) so we've spent a lot of effort on our security model: https://layerci.com/security
Why are grandiose narcissists more effective at organizational politics?
"LayerCI is an all-in-one devops platform, but we provide three main value propositions to our users:"

- Run e2e tests on every commit.
- Collaborate easier with per-PR staging environments.
- Set up CI/CD to build and deploy to production

Anyone can do this without your company. If that's the value you bring, then I don't need your company. What value do you bring that I can't get somewhere else?

Also, red flag: mis-use of the term DevOps for marketing purposes.

"There are a few ways of thinking about these files named ‘Layerfile’:"

- Auto-discovered Dockerfiles that build entire virtual machines instead of containers, just as quickly.
- Define a tree of virtual machines. Each subsequent layer can inherit all the running processes in its parents.
- Trigger specific actions like build, push, test, and deploy in parallel every time you push new code.

It's not explained well what benefit there is to using VMs rather than containers. Later on it briefly mentions possibly better caching than Docker containers. If it's actually better than Docker, you are severely burying the lede. "Better than Docker" should be on the front page. It's also not explaining whether I need to throw away all the time and money I might have already invested in containers, or what this is and isn't compatible with.

A lot of this solution is really built around optimizing one specific problem, which is caching during re-running whole CI pipelines. This limits the viability of your business. As soon as your customers figure out a new way to solve this problem, they don't need your custom platform anymore. I would consider LayerCI more of a specific feature of a much larger offering.

(In particular, the 'correc't way to solve this problem is to stand up an environment for your PR and structure your CI so you only re-run the parts that affect the particular change you want to make, rather than re-running the entire pipeline. It involves putting more thought into running your pipeline but often means the only tasks that get executed are copying a file and restarting your app)

P.S. You're installing the yarn GPG key and then not doing anything with it. Your node setup script isn't installing the yarn repo or yarn itself, so this is a throwaway command.

maybe it's not collapse yet, but it certainly isn't making the city an easy place to live, and seems to fit the precursors mentioned in the article. the paper valuation of real estate and landlords don't make a city. referencing their efficiency of extraction as a metric for city health works right up until the moment the burden becomes too great.
Yes, same thing noticed here. Incoherent sentences above, in your parent's comment.
DTCC is not a villian. You would have the same problems for any settlement greater than T+0 and in the limit T>0 the problem actually increases as you eliminate the possibility of netting positions.
> That's an anecdote; facts are that serious critical bugs that lead to privilege escalation and loss of data have existed in codebases that would surely have been caught by various static type systems.

An anecdote at this point is at least better than a baseless claim as you're making.

Also keep in mind the article is in the context of Lisp, so it would be static types on top of a garbage collected memory managed runtime with runtime type checks.

Do you have a family? Can you stay with this company, but work remotely in a different place in your country or another one? Either a satellite office or an AirBNB for a month next to a forest, mountain or ocean?

I say that because a change of scenery will jumpstart hope and creativity.

I understand the sentiment though. It might also be worth looking for a new job. I find personally that job positions rot like fruit, and I hate staying somewhere more than 2 or 3 years. I can't understand people who stay in the same role for 5 years or a decade, and find that satisfying.

Try a change is my prognosis. You will get better insight into your feelings.
I'm just a finance enthusiast, so take what I say with a grain of salt. Now that GME is clearly overvalued, that makes the shorting even more expensive. The borrow fees that Melvin capital owes for their shorts are less than the current ones (iirc ~25% vs ~50%). If you're a hedge fund that wants to make money to short GME, it would make sense to buy the shorts off Melvin rather than the public market. Melvin itself does not have the liquidity to maintain these shorts, but Point 72 and Citadel likely do.
I genuinely dislike Apple but their CEO has just shared some insights that very much go against your premise of social networks as just another harmless entertainment industry.

"Will the future belong to the innovations that make our lives better, more fulfilled and more human? Or will it belong to those tools that prize our attention to the exclusion of everything else, compounding our fears and aggregating extremism, to serve ever-more-invasively-targeted ads over all other ambitions?"

As the saying goes, viruses on Linux are hard to get right because you need to make assumptions about API/ABIs

The Linux system call interface is stable. Or if you want to go up one level of abstraction, glibc has great backwards compatibility (using versioned symbols).

GNU/Linux viruses are fairly uncommon, because (virtually) no one uses Linux on the desktop. So, it is much harder to spread.

(Disclaimer: not a bashing attempt, I use Linux on the desktop.)
Greedy developers don't want to drive the value of their existing properties up, they want to build more properties because that is an easy way to double or triple their money.

Greedy owners of single family housing want to drive the value of their house up because they can't easily invest into a second home. A lot of them also love the idea of halting progress at all costs, even if it harms them or their children in the long run.
> Plus, some articles are claiming[1] that even stock you do own, whose purchase long ago settled, is being lent out without your direct knowledge by the broker for a profit, which is like ... what?

That's how your "free" trading account is paid for. If you don't like it, fine! Just be prepared to pay per trade and per month.
Well... here in Europe the EU parliament passed laws that created the unified payment area (SEPA) as a first step and then forced the banks to offer overnight transfers. The current aim is instant payments, especially to reduce the dominance of Paypal.
By "things" it seems you ignore the key bit of the parent I was replying to... namely "technology," especially within the confines of the main article which focused on UX.

Specifically I used the word "changing" rather than "improving" because within the tech world (and to a degree the larger world of product) there is a long history of new and novel equating to better, hence the tired ad slogan "new and improved!" That emphasis on newness as desirable is a result of the many measurable improvements that did result from the rapid pace of innovation that occurred in the 19th and 20th century, improvements that were obviously perceptible in that they resulted in large leaps forward vs incrementally over long time periods.

Also, to claim that there has been improvements for large-scale populations via some new thing is nowhere close to being sufficient to explain how that new thing is an improvement for the individual customer.

>glibc has great backwards compatibility (using versioned symbols).

As long as the virus or other software dev can restrain themselves from using the latest added features to glibc and c++??. Usually they can't so compiling something written with today's libs on a distro from 5 years is infeasible.
> There are multiple options like this for Pulseaudio,

So they should penalize all their other clients who are not involved in trading GME? Everyone else should pay the price because DTCC raised collateral requirements to settle GME trades?
Those things weren’t proven over and over again to lead to massive depression and mental health issues.

TV ok somewhat bad but not all bad. It made us all on the same page, believing the same facts and entertained. Radio had to be pretty much all good. A kid listening to old radio shows laying in front of the console was in pure heaven. Facebook, etc. is purely detrimental to humanity like cigarettes or meth.

I’d post the references but there are simply too many. I’ve never seen a study that didn’t find Facebook, Twitter, etc. detrimental to mental health.
Last year I was working Monday & Tuesday. I spent Wednesday relaxing, watching TV, reading books, and then Thursday & Friday looking after our child.

Working two days for money, parenting for two days, and having a break in-between was perfect for me.

Sadly due to circumstances I had a need for more income, so I went back to working Monday-Friday, but it was still an excellent experience for the months I managed it. Zero regrets.
Radio, books and TV often bring a lot more intellectual development and perspective than engagement-optimized content.
I’m surprised SICP isn’t on the list.
> why not study both

Because no need. Technologies come and go all the time. They can be learned on the job anyway. With the right mental models that we developed by studying fundamentals, we get to pick up specific technologies quickly too. Studying in our spare time is an investment, so we need to treat our time as the most precious resource.
I did something similar with an old server a friend of mine acquired from a internet company that had gone out of business.

I remember taking out ALL of the fans AND trying to put it under an arm chair and it was still the loudest thing in my apartment. Needless to say, I got rid of it not long after that.
Yes. I used to work at an investment bank. When the market moved from T+5 to T+3 it was a major project for all internal systems to be adjusted. It wasn't just a matter of changing a SETTLEMENT_DAYS macro in a header file. And even afterwards, it wasn't that, because there were different systems written in different eras and in different languages.

Multiply this by however many thousands of firms, all with their bespoke back-office systems. and it takes time.
> - 10 hours / month of maintenance + 200 hours of setup @ $60/hr = $13k in the first year, not including any infrastructure costs.

Impressive numbers! would love to do these for you for a tenth of the price you are quoting, I'd still get like a 400% margin or something. GitLab runner is just installing the package with apt and running the register command once, then updating just magically happens when you upgrade the system.

As for infrastructure, you will find dedicated servers that will perform extremely well for an equivalent 49$/mo/developer.
It's not an argument in favor of creating a bubble and letting it pop. The argument is that even in the most extreme scenario that building more housing will lower the cost of housing in the long term. Even expensive housing will make the rest of the housing market affordable.
Because that's not actually the problem. If it was just ACH deposit clearing time, I'm sure they could have found bridge money rather quickly for that as their ACH failure rate has to be tiny.

The problem was clearing house margins. It went from a few percentage points every buy of GME to 100%. You cannot use customer money for these deposits, it must come from the brokerage firm's funds itself.

I think it really needs to be discussed that there were multiple "liquidity" crunches for RH here, one far more significant than the other.

You could have had every single buyer of GME locked and loaded with $100k of cash in their account for a month, but if they all bought GME last week for cash RH would still have the same exact margin requirement problem they have now with their clearing house. That they still had hundreds of billions of their customer's capital on deposit would have been irrelevant.

Interviewing in tech is often pretty broken, especially when it comes to whiteboard-style CS interviews.

With that being said, the largest and most esteemed tech companies such as Google, Facebook, Amazon, Microsoft, etc. all still employ very similar technical interview loops that tend to greatly favor candidates with standard computer science backgrounds over candidates who are either self-taught or who prefer to focus on software engineering over the “science” aspect of computer science.

So here are my favorite tips for gaming this outdated system and kicking ass at whiteboard interviews.
