Juniors from non target schools are getting pushed out since the skill floor is too high. I graduated 9 months ago. In that time I've merged more PRs than anyone else, reduced mean time to merge by 20% on a project with 300 developers

I vibe coded a Kubernetes cluster in 2 days for a distributed compilation setup. I've never touched half this stuff before. Now I have a proof of concept that'll change my whole organization. That would've taken me 3 months a

If only I could get into a Google AI team! Unfortunately I didn't graduate from Waterloo nor did I have referrals last year, so Google autorejects me from even forward deployed engineer roles without even giving me an OA. Instead I get

Western militaries have a parallel commissioned officer and enlisted command structure where an O1 (junior officer) is technically senior to an E9 (senior enlisted NCO) and can order them around. The idea is that command requires a separate

I like this concept because everyone's thought of "commit the agent prompts and reproduce everything from scratch every time" as a "dumb idea" I'm unsure if anyone has actually executed on it in a snappy git-li

I took it off LinkedIn and replaced with time to merge reduction of 20% over two weeks of PRs (rounding down). I expect to justify the expenditure to non-technical managers in my current role, which is why I picked $s. > All of this scre

It's definitely a resume number I calculated as a junior engineer. Feel free to give feedback on my math. It is based on $125/hr and it assumes review time is inversely proportional to number of review hours. Then time to merge ca

I just avoided $1.8 million/year in review time w/ parallel agents for a code review workflow. We have 500+ custom rules that are context sensitive because I work on a large and performance sensitive C++ codebase with cooperative

Most normal people want the LLM to remember their interests and favourite things, so they don't have to manually re-explain when asking for advice. They also don't know what "context" is or that the LLM has a limited num

50% paycut for similar cost of living. Do you want to put 3 kids into a 2-bedroom apartment on your US$120k salary, with $10k of RSUs the government takes 53% of? In addition to a 13% sales tax?

It also doesn't mathematically make any sense. If you now have 130% developer capacity, then the percentage of developers you need to keep is `x` defined by 130%*x = 100%, x ≈ 76.9% implying you'd lay off about 23.1% of developers

Some examples of complex transformations linters can't catch: * Function names must start with a verb. * Use standard algorithms instead of for loops. * Refactor your code to use IIFEs to make variables constexpr. The verb one is the b

You need human alignment on what constitutes a "good" comment. That means consistent rules. Otherwise, some people feel review is too harsh, other people feel it is not harsh enough. AI does not fix inconsistent expectations. >

The reason those countries take the "burden" on is because the USA became a global superpower by developing more industrial capacity than literally every other country in the decades prior to the World Wars. They want to duplicate

In my view, this is a good thing. As a C++ developer, I regularly deal with people that think creating a compiled object file and throwing away the source code is acceptable, or decide to hide source code for "security" while dist
