master_crab commented on Good system design   seangoedecke.com/good-sys... · Posted by u/dondraper36

> I’m often alone on this. Engineers look at complex systems with many interesting parts and think “wow, a lot of system design is happening here!” In fact, a complex system usually reflects an absence of good design.

For any job-hunters, it's important you forget this during interviews.

In the past I've made the mistake of trying to convey this in system design interviews.

Some hypothetical startup app

> Interviewer: "Well what about backpressure?"

>"That's not really worth considering for this amount of QPS"

> Interviewer: "Why wouldn't you use a queue here instead of a cron job?"

> "I don't think it's necessary for what this app is, but here's the tradeoffs."

> Interviewer: "How would you choose between sql and nosql db?"

> "Doesn't matter much. Whatever the team has most expertise in"

These are not the answers they're looking for. You want to fill the whiteboard with boxes and arrows until it looks like you've got Kubernetes managing your Kubernetes.

Nothing against your content…but Kubernetes does manage Kubernetes.

That becomes obvious when you start bootstrapping an HA cluster with multiple control plane nodes.

K8s is not for the faint of heart…or rational system designers ;)

This is LLM stuff.

No discussion of route53 profiles. More importantly it doesn’t seem to make the connection with GCP’a excellent implementation of projects and AWS’s half convoluted answer RAM (although they have started to address this with projects in Unified Studio).

master_crab commented on What does Palantir actually do?   wired.com/story/palantir-... · Posted by u/mudil

It delivered two things, and the easy response to your fair point is tactical tools — a rifle, great software — don’t win wars on their own.

1) Palantir was the first breath of fresh air that brought actually good tech with modern tech support practices to the warfighter, and by extension put the big defense contractors on notice. I personally believe this impact was tremendously important as there were real safety connotations involved, and anyone with a family member downrange could appreciate this.

2) Palantir was great targeting software that worked like modern tech vs a custom Linux distro with a GUI from 1970 and required 5 months of finagling to get vendor support for.

So Palantir just brought standard 2010’s tech to soldiers betting their safety on it. This was incredible although ordinary.

There’s a name for that: technical arbitrage. Not something you can build a long term company on, because others get wind of it sooner or later.

Hearing from multiple sources that there is big uptick in "offshore / global development centers" in India to support US companies who are currently using H1B in sizable numbers.

With the increasing standardization of application stacks, automation, AI (seems mostly just hype), companies are thinking even if they need developers in larger numbers they can most definitely do with cheaper offshore developers.

So US government, offshoring nation's government and American companies and their vendors are ironically on same page that H1B is going out. Even if they have different benefit or loss with current system.

Yup this is definitely happening. However, I’m not sure how effective it ultimately is. India is an incredibly inconvenient time zone for US based operations. And salaries are creeping up in Bangalore (the preferred city for this stuff).

Funny how a completely ordinary and incredibly useful vehicle ends up with such a skewed image in the US.

In Europe, a Ford Transit is just what the local plumber or electrician drives. It's a no-nonsense work tool. In America, thanks to what I assume is decades of media tropes, the same van is portrayed as the getaway car in a heist or the “creepy unmarked van” parents warn their kids about.

It’s as if a hammer were seen as suspicious because it could be used in a crime.

You’re thinking of the Econoline or E-Series in the US. Those are the panel vans that have been stereotyped as “creepy vans”
