JackFr··on Citigroup Plans to Cut 20k Jobs
Their competitors are BofA and JPMC.

All three feature an investment bank, a commercial bank and an asset manager. There are a number of smaller operations which have all three but none at the scale of those three. Wells is much smaller, and HSBC isn’t a US bank. Goldman and Morgan Stanley don’t really have a commercial banks and neither do the mega sized asset managers like Blackrock.

So the thing is Citi isn’t really a bad commercial bank and is really useful for corporate treasury services if you’re a large multinational company. Their international footprint is huge and fit a lot of use cases it’s either them or HSBC.

The problem is the IB and AM are ‘meh’ and hugely inefficient. It’s not like they do such a terrible job from a customer perspective. From an investor perspective it just costs so much to do it.

Also note that 20K jobs is 6-7% of Citi’s workforce.
JackFr··on Epistemic Learned Helplessness (2019)
I have to admit a weakness for reading not-quite-crackpot-but-likely-wrong theories. In particular, big fan of Julian Jaynes and The Development of Consciousness in the Breakdown of the Bi-cameral Mind, and the aquatic ape hypothesis https://en.wikipedia.org/wiki/Aquatic_ape_hypothesis

I get that they're probably not true, but I do enjoy reading novel thinking and viewpoints by smart people with a cool hook.

Forget air traffic control - who new ground control was so difficult and fraught with danger.

I believe that's why in some contexts you'll hear "niner" rather than "nine" ti differentiate it from "five".

Also why ships use "port" to mean the left side. It was formerly "larboard" which sounds an awful lot like "starboard",

I think the big takeaway is that scale-to-zero customers aren't where they're making their money.

Maybe your empathy towards caterpillars says more about you than it does the caterpillars. It’s difficult for me to imagine being a caterpillar let alone a paralyzed caterpillar being devoured from within.

Why is there any more or less moral weight to the wasps lifecycle than any other predator along the food chain?

JackFr··on SpaceX Illegally Fired Workers Critical of Musk, Federal Agency Says
The specifics if this case notwithstanding (I recognize that communications about workplace conditions are protected), if someone was on a slack channel, bulk emailing other employees undermining and disparaging their manager, were asked to stop and they didn’t, isn’t that grounds for termination?

They’re free to speak and tweet about it all they want. They’re just no longer an employee.

JackFr··on SpaceX Illegally Fired Workers Critical of Musk, Federal Agency Says
I understand that in this case communications about workplace conditions may be specifically protected, but is there some level of insubordination for which you think employees should be allowed to be fired?

JackFr··on How is AI impacting science?
I was being sarcastic, I don’t think I was necessarily being glib.

I suppose the deeper point I was trying to make was that “this time is different/special” is shallow thinking, as is believing that the real issue is with our “current greedy short term thinking”.

The real issue is the human condition, which remains largely as it has throughout our history. We need to choose a way to live knowing we will die, and then live that way.

JackFr··on How is AI impacting science?
Chipping flints into sharpened edges may not be a good thing. Sharpened flints can also be stone axes, spear heads, etc.

But beyond that, we should not have such easy to access cutting technology. It’s just too much power for our current greedy, short-term thinking.

JackFr··on NY Times copyright suit wants OpenAI to delete all GPT instances
I think LLMs may really change the IP landscape.

Culturally we’re taught that there is a moral component to copyright and patent law - that stealing is stealing. But the idea that words or thoughts or images can be owned (and that the might if the state can be brought to bear to enforce it) would seem utterly ludicrous to someone from an earlier era. Copyright and patent laws exist for practical, pragmatic reasons - and seemingly they have served us well, but it’s not unreasonable to re-examine them from first principals.

JackFr··on Should we tell people it's too late to save civilization?
The Plague of Justinian killed between 40-60% of the eastern Roman Empire in a decade. Pretty sure that disrupted some supply chains and yet humanity and civilization persevered.

TFA is simply a laundry list of early 21st century faddish conceits to describe the eternal brokenness of man. I liked it better when it was called it original sin. “Micro plastics”, “forever chemicals”, etc. aren’t evidence or argument, they’re an incantation repeated as part of a cultural rite.

My (possibly incomplete) understanding of ‘gardening leave’ in finance is that it’s based on the idea of specific knowledge of trading positions or specific deal term sheets. It’s not that you can’t compete against us in general or use general techniques, but for 30/60/90 days you have specific knowledge of ongoing operations you can’t use.

JackFr··on Do you really need foreign keys?
> I used to work on an application where ALL database accesses were via stored procedures. Genuinly the best dev experience, to me, so far.

I found such an environment to be simply terrible.

In general, I think stored procs certainly have their place, but if ALL access is through stored procs, you better have a schema that’s basically set in stone otherwise dev will turn into a nightmare.

JackFr··on Do you really need foreign keys?
Indeed - I immediately thought of hypothetical system (similar to many systems I’ve worked on) where SELECTS are 100x more common than INSERTS which are 100x more common than DELETES.

The 5x speed up on delete performance is a useless optimization.

JackFr··on Own the problem, not the solution
Sometimes Kubernetes is the answer.

I don’t need Google scale, I don’t need all the bells and whistles, but what I get is abstracting server infra, and pushing it onto a dedicated corporate wide team.

Does anyone writing that really think Einstein said that? Apart from it being completely apocryphal, it’s a terribly shallow appeal to authority.

This. I was looking for this in the original article. Thanks for following up.

I really prefer learning these aspects of philosophy rather than more ethics oriented topics but it’s really such a rich subject.

JackFr··on Toxic comments are associated with reduced volunteer activity on Wikipedia
> Eventually, after some fairly harsh replies, he went away, and the pages stand to this day.

Which brings up the point I was going to make about TFA. If 'toxic' comments are an effective way to reduce the impact of bad editors, then it's not clear that 'toxic' comments have a negative effect on the quality of Wikipedia. They might be improving it.

The thing is, Facebook was never awesome. Really. Never.

It demonstrably reduces happiness and life satisfaction. It’s just bad.

JackFr··on I worked in Amazon HR and was disgusted at what I was seeing with PIP plans
Replying to this 3 days late, so likely this won’t be seen, but I assure you the retention factors are not being ignored. (Well … see my last sentence.). For 2 years in the early nineties I worked in software with an extensive, sophisticated retention model.

Direct pay, benefits, promotion velocity, source of commission were all extensively tracked and modeled. The problem at that point was that you can claim you want a 600 ship navy, but if you don’t have enough surface warfare officers with the right number of years (or dentists or chaplains or JAG lawyers) it’s not going to work.

On the other hand despite our multimillion dollar contract to work on this software, I have no idea if BUPERS actually used it.
