Outdated, opinionated, platform-specific, and incorrect.

Their profile generally comes up here on HN very often with Dunning-Kruger effect like comments so it makes me believe it is no AI. AI would do a better analysis, for the better or worse.

Implementing a Redis and Kafka rewrite (in Rust) but with workload-aware and self-balancing JIT-like engine deployed at Datadog-scale is no fluff. You obviously have no idea what you're talking about.

So you read the three-part series of blogs that are packed in details in 3 minutes after I shared the link and put yourself into a position of entitled opinion and calling my position a silly take? Sure thing.

Let someone from the Redox team go read [1], [2], and [3]. If they still insist on keeping their position then ... well. The industry is being redefined as we speak and everyone doing the push-back are pushing against themselves really. [1]

Yes, there aren't and it's a quite competitive market too.

6500 EUR net in Berlin/Munich would equate to ~140k EUR gross. For a FAANG salary, considering that startups pay these figures for similar expertise, I would expect more. What level is that if you don't mind sharing?

What does it mean "remotely competitive combustion engines"? China has been building ICEs for decades, that's for sure, and if they had not been anywhere to remotely competitive people wouldn't be buying them and therefo

by menaerus 7mo ago
I agree with some of your points, they make sense, but China has been building combustion engines too, for a very long time which is why I don't think that sidestepping the technology with EV was the main reason for their success

Yes, I agree, and my experience is the same - there's just too many folks getting stuck in that mindset and never leaving it. Looking into the history I think software engineering domain has a lot of cargo-cult, which is somewhat surpr

Yeah ... and so it happens that this particular function in the profile is just a symptom, merely being an observation (single) data point of system behavior under given workload, and not the root cause for, let's say, load instruction

Sure, this is why I said likely. If you are good in both then I believe this isn't something commonly found in people.

Maybe you can learn to be mediocre or good enough designer or similarly good enough or mediocre engineer. But I don't think you can actually learn to be a great designer or great engineer - it just takes a different set of skills and e

To my understanding this is akin to what profile-guided optimization (PGO) in C or C++ does.

Why not? Even without LLMs it is technically feasible to build custom database engine that performs much better than general database kernels. And we see this happening all the time, with timeseries, BLOBs, documents, OLTP, OLAP, logging et

If you look into the results, you will see that they are able to execute 5x TPC-H queries in ~200ms (total). The dataset is not large it is rather small (10GB) but nonetheless, you wouldn't be able to run 5 queries in such a small amou

Over-hiring is a myth IMO. Company wanting to hire essentially has two options: (1) hire from the pool of fresh candidates coming out of the Universities, (2) hire people who are already employed. This means that to inflate the numbers of s

No, that's not how I believe they intended it to work. They generate the workload-specific engine up-front and not when the query arrives.

It has different limitations but inefficiency doesn't seem likely to be one of them. Did you read the Experimental Results section? > Figure 2 shows the experimental results, and GenDB outperforms all baselines on every query in bot

You have to rebuild the factory and manufacturing process I guess. Humanoid robot is a drop in replacement for human requiring no intervention

by menaerus 7mo ago
It makes sense when you find out that there's only so much humans who want to do and are capable of doing that type of work. Also, robots are cheaper, and they are the opposite of humans - theyt are not emotional, lazy, feeling fatigue

They all look the same, e.g. like sh*t IMO, so although the above statement sounds overgeneralized it doesn't meant that it doesn't generalize well. IME it does.

No, it's not mythical but it is vastly more difficult and more complex than the majority of other software engineering roles. Entry barrier being lower elsewhere is not something I would argue at all. It's a common sense. Unless y

Ah, I see. Thanks for the example. I think I understand now. In C++ problem of monomorphization, or potential bloat due to excessive template instantiations, is normally handled at the linker level but can be controlled at the code level to

That's polymorhpism 101, and not quite what I was asking. From my understanding what Rust has is something different to what C++ is offering. In C++ you either opt-in for static- or dynamic-dispatch. In Rust it seems that you can mix b
