    Who is more impactful, the startup engineer who singlehandedly ships a feature that increases a startup revenue by 25% off a base $5M/yr ($1M extra rev), or a Meta/Google team of 5…

    What field has interviews without silliness like this. Jobs for lawyers in 1950 when all that mattered was your father and your alma mater? Hard pass. I would take a interview prem…

    The native tool use is a game changer. When I ask it to debug something it can independently add debug logging to a method, run the tests, collect the output, and code based off th…

    Living off 20k a year in a Hcol, where these salaries primarily occur, is next to impossible. Rent alone anywhere in SF area, for example San Jose, is 2k at a bare minimum for a 1B…

    Is there a OSS license that specifically precludes its use in LLMs or effectively does so?

    Twitters data cannot fit on one machine. In 2015 their Hadoop cluster was 30 PB per earlier comments/their blog. How do you fit that on one machine?

    They did not spend half their revenue on compute. It’s more like 20-25% for running data enters/staff for DCs. Check their earnings report. Whats app is not an applicable compariso…

    Excluding a settlement from 2014 that was paid this year, Twitter would have made 500mil on 5B revenue in 2021. They were also GAAP profitable in 2019. Additionally, the incentive …

    SRE is a mix of both. The expectation is you are able to write and understand any code the team is responsible for.

    Yes that is the normal case. The post was refuting the assertion that one engineer can run these services indefinitely as previously the OP had the help of SWEs oncall and also fix…

    One SRE, many SWE. Also have fun asking someone to be permanently oncall with one person on the team. The cache clusters size are also described here for anyone who wants a good te…

    Nothing, because they don’t understand RecSys which is half of ML at social media companies. Probably could help with prediction for ads but the domains are very different.

    Printing code on paper definitely happened. Confirmed by multiple folks. The layoff 75% numbers and layoffs before Nov 1 were false though. https://twitter.com/leahculver/status/15…

    IME for engineering at these companies is that the social or political side of things is mostly irrelevant for Eng. Some folks want to be involved in internal activism but it’s eas…

    Does graal native perform better than a non-native running with JIT compilation?

    I think this is an unhelpful comparison. Simply put, when users exchange messages on WhatsApp it causes minimal traffic to a WhatsApp data enter as it’s mostly p2p. No ads, no pers…

    That is very helpful, thank you! Good point on load balancing, and also retries, back pressure, etc. would change it as well.

    Interesting, anecdotally at a faang adjacent company, I do not know of any Seniors who do not have code as their primary output. Even a large majority of staff actively code IME.
