Provided one can go through the silliness of fitting golf balls into planes, or going through the algorithms and data structures books from 30 years ago.

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 premised on a know, learnable challenge (even if silly) over one that exclusively relied on what college you went to.

I feel like Cursor gives the same experience without having to be in the terminal. I don't see how Claude Code is so much better

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 that until the tests are fixed.

I think theres a point of compensation that you reach where you just stop caring about the work or the company. If I was being payed that much a year, I'd be thinking about retiring early and trying to leave the working stiff life in as short of time as possible since with that compensation, its actually realistic to become a feudal lord in a few years especially buying into the market in a recession and riding the wave in the following years. 2-4 years of experience tells me they are right out of college too, so if you are fine with that standard of living you could realistically be living off 20k a year or less and the rest is just banked. Then in the back of your head you think if you ever do get laid off, you now have a title that was compensated at that much on your resume and new doors open for you, which you can take time opening with your massive nest egg.

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 1BR, or 3k for a 2BR split between a roommate at 1.5k each. That means rent is 18k-24k, not to mention other living expenses (car, utilities, food, travel to visit family, etc.)

If Twitter's data can fit on one machine, then the data of 99.99% of companies can. Not every product needs a billion users with Gigabytes of storage each. The assumption that if your startup's tech isn't scalable enough to become the next Google then it's the wrong tech is hilarious nonsense driven largely by ego fantasies.

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?

Genuinely asking, why do you think Twitter needs 24 million vcpus to run?

This is not apples to apples but Whatsapp is a product that entirely ran on 16 servers at the time of acquisition (1.5 billion users). It really begs the question why Twitter uses so much compute if there are companies that have operated significantly more efficiently. Twitter was unprofitable during acquisition and spent around half their revenue on compute, maybe some of these features were not really necessary (but were just burning money)?

mapme · 3 years ago

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 comparison because messages and videos are stored on the client device. Better to look at Pinterest and snap, which spend a lot on infra as well.

The issue is storage, ads, and ML to name a few. For example, from 2015:

“ Our Hadoop filesystems host over 300PB of data on tens of thousands of servers. We scale HDFS by federating multiple namespaces.”

You can also see their hardware usage broken down by service as put in their blog.

Twitter was losing millions of dollars each day. It wasn’t profitable or even break even.

An engineering culture that’s awesome at a company like that will only last until the money runs out.

I’m not supporting what Elon is doing. I’m just saying that what Twitter was doing before wasn’t sustainable or on a path to being sustainable. The culture was part of that

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 from wall street is to spend all your money to grow users. Whether that is right or wrong it’s the path they chose which led to users and revenue roughly doubling over 5 years.

The OP claims he did the implementation (so he was the software engineer too?):

> I designed and implemented most of the tools that are keeping it running so I think I’m qualified to talk about it.

mapme · 3 years ago

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

SWEs can share the oncall rotation with SRE.

mapme · 3 years ago

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 fixing bugs.
