moltenguardian··on Fuchsia IDL Overview
Are old applications going to run on new kernels? If so, backwards compatibility is a primary goal of an IPC dialog.
moltenguardian··on Fuchsia IDL Overview
To get promoted, of course. Perf is just around the corner.
moltenguardian··on How to Design Better APIs
gRPC is encoding agnostic, and requires _no_ Protobuf at all.

See: https://grpc.io/blog/grpc-with-json/

moltenguardian··on Bugs in Hello World
Even Golang de facto suffers from this. I don't think I can name a time I saw someone check the return value of fmt.Print or log.Print. Not checking the return value still seems the the "right" thing to do.
moltenguardian··on Passwordle
Someone more capable than I should make the final form of this: No green or yellow feedback is provided, but only the timing information used to calculate it. If cryptographers are serious about side-channel attacks, why not show off the danger using no-information Wordle?

(edit: Absurdle was taken)

moltenguardian··on What does it mean to listen on a port?
Are you referring to SO_REUSEADDR?
moltenguardian··on Samsara S-1
The best piece of advice I heard for reading financial reports: start at the bottom, read your way up. All the juicy stuff is hidden in the bottom (like losses), while the pretty, extrapolated ARR graphs are up at the top.
moltenguardian··on Go does not need a Java-style GC
gRPC Java wins in part due to not allocating memory when reading and writing buffers. It uses Java-based implementation of jemalloc (via Netty) to manage its own memory. No/low allocations means the GC doesn't need to wake up so much.
moltenguardian··on Amazon Ion – A richly-typed, self-describing, hierarchical serialization format

moltenguardian··on Lebanon's central electricity grid shuts down as fuel shortages continue
Lebanon defaulted on its debt in March 2020, followed by the Beirut explosion later that year.
moltenguardian··on Ten Commandments of Salary Negotiation
For those of you here that have hit your FIRE number: have you ever brought this up with your manager or potential new company? I'm in this position myself where I don't have to work any more, and mainly just want a fun job. I don't want to be underpaid for the value I'm providing, but I also don't want to be jerked around.
moltenguardian··on Personal finance experts don’t get wealthy by following their own advice
"Rich Dad Poor Dad" also made a similar point: you should look at what your advisor is doing, rather than taking their advice. If your financial advisor suggests a mutual fund, ask them if they themselves invest in it.
moltenguardian··on Personal finance experts don’t get wealthy by following their own advice
Considering the majority of CEO pay is in company equity, they are working for themselves.
moltenguardian··on One simple design fix for the Olympic medal tally
A different way of thinking about it would be considering each Olympic trial as a voter and use gold/silver/bronze as 1st/2nd/3rd in a ranked-choice vote. Each "contest" effectively votes on a country.
moltenguardian··on Bacon may disappear in California as pig rules take effect
> I'm totally fine with paying more for bacon if it means that pigs will be treated more humanely.

The problem is that these price increases are regressive, and disproportionately affect the poor.

moltenguardian··on Americans' life ratings reach record high
Wow, the graph of happiness almost matches the S&P500 returns.
moltenguardian··on JVM Anatomy Quark #26: Identity Hash Code
It doesn't cost as much as you might think. The word it's stored in is overloaded with the object lock and garbage collection bits.
moltenguardian··on How useful was the Netflix Prize challenge for Netflix?
Up until the beginning of 2020, NFLX was the highest growing stock of the decade. (Dethroned by TSLA) In terms of percentage growth I believe it still outperforms every other component of FAANG.
moltenguardian··on A Pure HTTP/3 Alternative to MQTT-over-QUIC in Resource-Constrained IoT
> Any protocol designed for the TCP transport must have been designed to work in concert TCP mechanics, not fight, or try to workaround it.

There is a reality of running code on other peoples hardware: they impose limitations on network traffic that you cannot change. Example: Home-grade routers do NAT, but have table limitations which make it hard to have multiple connections. The connections get dropped, and users complain, not realizing it was due to them having bought a cheap router. Other actors in the network path between the client and the server impose their own limitations, making it hard to have multiple connections. (corporate firewalls being another big one).

HTTP/2 is a compromise, admitting that it is not possible to go fix or replace all this hardware. I worked on a few HTTP/2 implementations, and the complexity it incurs is significantly less than the alternatives.

moltenguardian··on Warren Buffett's bet against hedge funds at the Long Now Foundation (2008-17)
Buffett is pretty much the exact opposite of a boglehead. Buffett's strategy is to only pick winners. Jack Bogle was in the portfolio theory camp, buying companies regardless of if they appeared good or bad. Both can be profitable, but the boglehead strategy is much easier to do.
moltenguardian··on Warren Buffett's bet against hedge funds at the Long Now Foundation (2008-17)
> Instead, it's that on balance, by far most managers don't beat the S&P 500 on an after-fee basis.

Interestingly, most managers actually do match the S&P500, but before fees. I don't have a link handy, but there have been some academic papers on their performance.

moltenguardian··on United B772 at Denver on Feb 20th 2021, engine inlet separates from engine
Probably a dumb question, but why don't the pilots cut the fuel to the right engine after they know it's on fire?
moltenguardian··on [dead]
Same question. If the securitization of the properties and pricing of the properties was exposed, this would be of a lot of interested to me.
moltenguardian··on What Is a Gamma Squeeze in the Context of Stock Trading?
Delta for put options is typically below 0.
moltenguardian··on What Is a Gamma Squeeze in the Context of Stock Trading?
Unlikely, for the gamma squeeze to work on TSLA, the Market Makers need to hold the shares after the options expire. Otherwise when the options close, they wouldn't need to maintain their exposure. For reasons we don't know, the shares remain high even after the expiration.
