arn3n commented on DRAM prices are spiking, but I don't trust the industry's why xda-developers.com/dram-p... · Posted by u/binarycrusader
I keep hearing about how the supply and demand cycles are “lagged” and that this price spike happens every 3-5 years for purely economical reasons. I feel like I’m being gaslit — I don’t recall any such price spikes in the past of this magnitude. You’re telling me that there’s a totally predictable price cycle and NO ONE has prepared for it? Or else prices are just high temporarily and no one can step in to increase supply? Either way, it seems that there’s not enough competition in this market.
arn3n commented on Universities should be more than toll gates waliddib.com/posts/univer... · Posted by u/wdib
I am always astonished by the range of people who claim their college degree was useless, citing rote memorization and bad classes. I had an entirely different experience and so did most people I know. University gave me the opportunity to talk to world-class researchers during office hours, to discuss ideas with my peers and have them either validated or critiqued by experts. Sure, all the information is available online (which is a miracle into itself) but without frequent contact with professors and mentors I wouldn’t have even known where to look or what existed in the field. University, for me, was a place where I was apprenticing full-time under highly experienced people, surrounded by people my age who also were doing the same. Years of self-teaching didn’t get me anywhere close to what a few semesters of expert mentorship got me. I never felt I had to memorize anything: exams consisted of system design or long programming projects or optimization challenges. I loved it, and I’m not sure if people went to different universities or just didn’t take advantage of the opportunities presented to them.
That's a simplistic way of understanding "best interest."
The optimal amount of fraud is neither zero nor "let it all through." Their "best interest" is a balance between allowing legit transactions to get through and blocking enough fraudulent ones that fraud doesn't become too common.
I believe you’re referencing Patrick McKenzie’s takes on fraud, which I agree with — but when he (and others) talk about the optimal amount of fraud they’re usually referring to fraud from “losing money from the company to customers”. This is not PayPal’s case; because PayPal isn’t the victim of fraud on its platform but makes money off its use, their optimal amount of fraud is “as much as they can permit without losing customers or regulators getting up their ass”.
I love conferences and talks and wish I could go to them more — what stops me is the sudden drop in corporate sponsorship of them. It’s been nearly impossible to convince leadership to spend money to train their employees or to socialize within their own discipline, and while I’d love to go to conferences, taking time out of my own PTO and my own wallet to see them isn’t worth it.

alpha in being good at both (if nothing else you can keep more of the desks pnl...)
In my experience it tends to be the opposite — I am not a quant (QD) but having worked with a few teams there’s a negative selection for technical expertise. QRs who are good at programming are usually pushed into maintaining infrastructure, datasets, or just tooling for less technical members of their team, who then get to use those tools to further their own alpha generation. Orgs incentivize the final step in making alpha — spend too much time helping others or building reusable research, and your coworkers steal the thunder.
That, or stop helping your coworkers/accommodating them… risky, as a career move. Only seen that work once.
arn3n commented on GLP-1s are breaking life insurance glp1digest.com/p/how-glp-... · Posted by u/alexslobodnik
Obesity is highly correlated with other medical conditions, from cancer to diabetes to heart disease. I wonder if there is a point at which it is cheaper for health insurance companies to offer subsidized or even free GLP-1s to patients than pay out for other specialized medications. For example, my insurance covers flu shots in my community every year because it's presumably less expensive to pay for the shots compared to the increased rate of hospitalization that the flu causes.
