caddemon··on Takeaways from the Jane Street bond prospectus
Than in the past? That seems untrue at face, do you have a source? Firms like JS recruit a lot of people that wouldn't have ever considered a traditional finance institution in any event.
caddemon··on Takeaways from the Jane Street bond prospectus
Being able to borrow that amount might be a bubble, but depending on the fund I don't think it would damage friendships at all. If you had access to the internal Renaissance fund for example I think your friends would be happy to get in on that.
caddemon··on Takeaways from the Jane Street bond prospectus
It seems their thinking is part of what led them to JS in the first place, which is a bit of negative and maybe they had some ideas reinforced there. But I also think they were some of the more extreme ones to begin with. They obviously didn't internalize JS's concerns about risk at all lol.
caddemon··on I rewired my brain to become fluent in math (2014)
I didn't even know what a matrix was until I got to college, and I went to a supposedly well-ranked high school and was on the higher level math track. This was about 10 years ago. I think some of the education reform might've removed concepts altogether instead of actually improving the presentation? Though I suppose in order to present things well you might need to cut back on the total number of topics covered, I'm not sure I'd describe what I did learn as well-presented either.
caddemon··on Jane Street raked in $4.4B at start of 2024
I mean negative moves tend to be more volatile than positive ones, but yeah I don't think "capitalizing on tragedy" is the right way to frame it. Financial conditions during bad news events would turn out worse if there weren't these market makers providing liquidity. Some pharma companies profited from COVID but it was because of valuable services provided. If they didn't "capitalize on the tragedy" we'd have a bigger problem lol.
caddemon··on Jane Street raked in $4.4B at start of 2024
JS does a lot of trading already where a few seconds don't matter. Firms like HRT and Virtu are more high frequency.

Either way I don't think this would resolve the issue with siphoning talent.

caddemon··on Jane Street raked in $4.4B at start of 2024
Jane Street is not a huge player in HFT, they are primarily a liquidity provider and therefore actually do enable people to sell stocks during a crash. Any registered market maker has specific rules imposed by the exchange about always needing to provide a 2 sided offer within a reasonable bound of the current market.
caddemon··on To make a fortune, target bored young men who want to make a fortune
Some of that is just social conditioning though, or maybe an innate instinct but an irrational one in today's day and age. There's no reason a woman can't be the primary breadwinner, and most high earning women I know are very open to dating someone with a much lower salary as long as they are a good partner. But more often than not the guy has a hang up about the situation or is otherwise unwilling to contribute enough around the house. So instead you end up with dual high income paying for cleaning service, daycare, etc.
caddemon··on MTA board votes to approve new $15 toll to drive into Manhattan
I mean there will be a delay of many years before the fixes actually happen, if that's even what the financing would go towards.
caddemon··on Show HN: I made a cheap alternative to college-level math & physics tutoring
The Piazza post isn't publicly viewable, but I'm surprised you had this experience at MIT. The majority of classes I took had a ton of materials online and there were few instances where I felt I needed to go to class purely because of an attendance policy or a reluctance to share materials. Office hours are designed to be 1 on 1 for educational reasons, but other students collaborating at office hours (or outside of them) was encouraged on psets. I wouldn't expect any of this to be worse post-COVID either. Maybe a course 8 issue? But I'd be sad to hear this was the case now with 6 or 18 because it certainly wasn't in the past (and MIT was way ahead of peer institutions on this historically, in large part due to OCW)
caddemon··on Japan brings negative interest rates era to an end with first hike in 17 years
It seems a small raise but yeah theoretically raising interest rates should strengthen the currency to USD, because with higher interest rates there is less reason to move the currency to USD. That's just the first order effect though.
caddemon··on The Dumber Side of Smart People
It's not just drug trials, it's a huge proportion of biology and psychology research at least. Additionally, most research in biology is expensive to get off the ground, and in order to get funding it absolutely is important to project confidence - there's an entire game surrounding grant writing that sounds a lot more like "group 2" than "group 1". Group 1 is just a theoretical ideal, not the reality of academic science. While that may be somewhat field dependent it's definitely not restricted to a small niche either.
caddemon··on The virtuous mean between time drunkenness and work martyrdom
How big was their house? 3 of my 4 grandparents grew up in multi-generational houses, all of their parents were very working class, and yes they "afforded" raising kids and housing their elderly. Their houses were not bigger than 100 sqm though. All shared rooms, and there was typically 1 bathroom for the entire household. Clothes were hand me downs and meals were only what they could afford, so the meat in their diet was mostly weird low quality stuff. They shared bath water! The lifestyle described is 100% still attainable today. It is your parent's choice not to have grandparents in the house - in line with societal standards today, but certainly not impossible.
caddemon··on Cellular outage in U.S. hits AT&T, T-Mobile and Verizon users
Minor in the grand scheme of things, but I thought interesting (or at least unexpected) - a bunch of rides at Disney World went down because they rely on AT&T push to talk for communication between staff, which is required for safety reasons to run some attractions.
caddemon··on Thanks FedEx, this is why we keep getting phished
I would be curious if FedEx specifically has some sort of leak though, it's super anecdotal but I seem to get more FedEx phishing attempts when I'm expecting a FedEx package.

You're right though that there are other mechanisms for this, it was around the holidays when this happened most recently. Plus humans tend to remember salient things and I probably more easily forget the ones that come when I'm expecting nothing.

Anyway, if their systems were better it would be easier to avoid scams without stress. I've never had to rely on external info for Amazon and it's true I'm often expecting something from them.

caddemon··on Thanks FedEx, this is why we keep getting phished
FedEx seems to be the worst option domestically too. Maybe it depends on your location but they're the only service that somehow fails to deliver signature required packages to my mail room. I've also tried to have them contact me directly while I wait at home and I've tried to waive the signature requirement online, but they still just say "delivery attempted" for 3 consecutive days and then hold stuff at their warehouse. Happened to me twice recently. I now try to avoid buying anything expensive that uses FedEx to ship.

A funny thing I discovered in this process is that "delivery instructions" are shared for all packages to a given address regardless of the associated name, and never flushed unless you go in and do it manually on their website. I found the name and contact information for the prior tenant of my unit on the FedEx site with no other info besides 1 tracking number to the address (it also let me change the delivery instructions with said info). Potentially they were still calling that person when they tried to deliver initially, though I have other reasons to doubt they actually came to the door that day.

caddemon··on It's time to admit that genes are not the blueprint for life
"We found a genetic marker for X" is even more fuzzy when talking about something like Schizophrenia or Autism, because the diagnosis itself is very far from a precise label. It's not just about missing environmental contributions or dealing with how complex interactions between different generic markers are, though these are also issues. We're averaging over probably dozens of different issues in the vast majority of studies, and that extends to other subfields of biological psychiatry too.
caddemon··on Remote work won, don't let anyone gaslight you to believe otherwise
That's his point though, 95% of the time people say "gaslighting" now it's not the right term.
caddemon··on The growing inequality of who gets to work from home
I think it depends a lot on the specifics, if the background noise is loud and persistent enough it makes it harder to understand the other person. Hard to tell from OP's description but I'm guessing it was actively impacting the conversation if they're complaining about it.
caddemon··on The growing inequality of who gets to work from home
Eh, some of the people I know with the worst WLB are people that do not take work that seriously during working hours. They end up living at the office basically because it takes longer for them to finish their tasks and they also end up with their social life/break time tied up in the company.

In this case, if it is disruptive enough to the call then that makes it take longer to get done what you need to do. The quicker you get done what you need to do, the quicker you are done with work. I'm not a fan of judging things just because they are "unprofessional" but there are unprofessional things that actually make everyone else's lives more difficult.

caddemon··on Ask HN: Help me solve a dilemma, study in the US or take a job in the EU?
I think the lifestyle part depends a lot on where in the US OP would end up. Places like Boston and NYC are not car-dependent at all and most people you will meet are a normal weight and have a decent diet. There is also a ton of cultural diversity within NYC and lots of amazing food (especially if you have disposable income). Boston has many students and postdocs coming from all over, so in an academic circle you will easily have a young diverse friend group. It's definitely a different lifestyle than living in some other parts of the US, which probably are more of a negative compared to EU - though if you're into nature there are some really beautiful sights in parts of the US that make for relatively cheap vacations. There's also something to be said for the US college experience, like I wouldn't want to live in a smaller college town as an adult but some of them are super fun while you're an undergrad.
caddemon··on Ask HN: Why am I suddenly unemployable?
I'm not sure about hiring in 3D graphics but my resume has two somewhat different paths on it and I've always made 2 separate resumes just by switching around the focus/how I frame things. Like the main header would have the most relevant roles with greater detail, but I still mention highlights from other work under a second header, because I don't think it's entirely irrelevant either.

Also, I think the process of doing this makes me consider more carefully what I'm trying to convey about each role, and what parts of the resume I want to draw the most immediate focus to for a given type of job app.

caddemon··on Test Can Tell How Likely a Young Driver Is to Crash
I think it's pretty normal to get a learner's permit like a year before your license, so you can theoretically do the 50 hours with a parent. But I've never seen that part formally enforced, you could just do nothing until you're of age for the license driving test. Mostly depends on your parents.
caddemon··on Lancet journal retracts article on hearing aids and dementia after prodding
Retractions can be healthy but in this case it seems to have taken a good deal of effort from another group, which isn't the best sign about the process of the original authors or the journal.

It's true there will probably be an increase in this kind of bad article retraction before we can see a decrease, and that wouldn't necessarily indicate an increase in bad science -- similar to certain crime statistics when reporting starts to be taken seriously. But I still think the article raises quite a few ongoing concerns with the current academic system, which does have capacity pressure/incentive problems to a much greater degree than previous generations.

I do agree retractions in general should be more normalized, as there are also plenty of cases where honest non-reckless mistakes were made, and sometimes even quality work that turns out to have issues in retrospect e.g. new information invalidates a previously common assumption. But I'm not sure any of that applies to this particular paper, and regardless the original authors apparently avoided addressing any of it.

caddemon··on Bad scientific code beats code following "best practices" (2014)
I agree, a lot of unmaintained code is due to turnover of staff and few considering the software as an important output in its own right. But I don't think it would be that hard to find grad students/postdocs who would care about code, if that were something the field properly incentivized. Not only does software contribution not check the right boxes for career progression, it is also often looked down on.

I find this especially laughable in biology... I've seen some (faculty) PhD committee members object to the student having a thesis chapter related to software contributions, because this is not "intellectual". But they are perfectly fine with one of the chapters being a wet lab paper where the student was a 3rd author who contributed purely through helping run experiments designed by the 1st author (e.g. handling mice, pipetting shit). There are PIs that simultaneously hold these two views, which to me signals a real misunderstanding of the challenges in and importance of writing decent software.

caddemon··on U.S. moves closer to filing antitrust case against Apple
I'm sure there are some obnoxious people out there, but also I think there is a bit of a social hit resulting directly from the poor functionality. People are often lazy and/or not super tech literate, so for example when someone wants to send a couple pics from an event they'll default to iPhone-only group chat to avoid destroying the quality of the image, rather than using a different sharing mechanism. This is sometimes accompanied by a misunderstanding that Android phones are at fault for the downsampling, when actually it is the iPhone causing the issue and getting away with it due to majority rule.

Additionally, when you first make the switch (at least circa 5 years ago), any iPhone-only group chats you were already in will need to be restarted (with some care taken by each iPhone user involved), otherwise you will not receive those messages because iOS will continue to treat it as an iMessage on others' end. It is very easy to miss out on communications this way, and from there it's not all that hard to fall out of touch with people who weren't closer friends to begin with. Either you need to be proactive or your larger social circle needs to be thoughtful and/or really like you.

So with all these issues, there is a bit of extra work involved for everyone when Android phones are involved. Some circles are so iPhone-heavy already it would be a little awkward to be that guy making the whole chat green. Couple it with a false perception that Android coincides with lower socioeconomic status (obviously not true for certain devices anyway) and it's easy to see shallow people being petty about them. Plus less tech literate circles just accidentally excluding people and you get a real fear of social hurdles.

caddemon··on U.S. moves closer to filing antitrust case against Apple
They don't need to open iMessage IMO, they just need to use better practices for text messaging between iPhone/Android. Like images are downsampled to hell if a single Android user is in an iPhone group chat -- but any time I've texted groups containing only various Android phones, images are decent quality (even if the members are using different text messaging platforms, so not like this is a Google Messages or Samsung thing).

Idc about green bubbles or cloud access/being integrated with the Apple ecosystem, but the core functionality should be decent. They should not be using outdated standards for non-Apple messages, which sure seems like a ploy to keep people away from Android.

caddemon··on The changing face of post-pandemic New York City
If the NYC <> Boston bullet train ever happens, Boston will be such an ideal place to live. I already prefer it to NYC personally, but it's true there are "tier 1 global city" things it can't offer. But if it becomes feasible to get door to door in under 2 hours? I suppose that could also change the entire character of the city over time though.
caddemon··on The changing face of post-pandemic New York City
Finance is pretty meta itself, which is probably a contributing factor to NYC having such a diversified economy. Like an automotive company might still want a business-focused office in NYC, but a non-automotive company doesn't have much reason to open an office in the auto manufacturing capital.
caddemon··on The changing face of post-pandemic New York City
A lot of schools remained remote in fall 2020 - depended on the school, and it's not exactly easy to switch between districts. Also, the quality of instruction in spring 2020 was absolutely affected as teachers adapted to remote and everyone dealt with the general chaos. Again could vary by school, but I think saying no instruction was missed is naive. "Days in class" is a horrible metric for learning, and there absolutely were classrooms where quality of learning degraded.

It was a shitty situation all around, and I'm definitely not arguing that schools should have remained open that spring. But it's silly to pretend that education was not affected across the country by the switch to remote.
