Golang has a GC and that makes a lot of things easier.

So perhaps a mixed read+write workload would be more interesting, no? Write-only is characteristic of ingestion workloads. That said, libaio vs io_uring difference is interesting. Did you perhaps run a perf profile to understand where the d

Maybe I mistook your position but that's not what my intent was. I just wanted to paint the picture from the other side too, and perhaps spark a discussion too. That's all.

The report uses the number of newly registered vehicles AFAIU and correlates them to the total % of Chinese vehicles sold, so that's not really the monthly sales but the general trend, no? Market cap amounts to 10% as an absolute figur

Interesting article. According to it, the missing piece is scaling the conversion facilities from 8% to x%, and then scaling uranium enrichment process from 30% to x%. With that in place heavy dependency to Russia+China would have been solv

It's wrong to assume incompetence, which is what you did to a comment which displays much deeper chain of thought about the subject. A more proper way of doing it would be to reflect over your own opinions and critically assess them, a

They do not find it favorable all of the time. If you look into the "What people are concerned about" section, these same people will call out the "Unreliability" as a top-1 concern. So, you can be excited and critical o

In your point you said "There is more to searching than building a basic similarity search." which assumed and implied all kinds of things and which was completely unnecessary. > In practice tools like Claude Code, Codex, Gemin

Sorry but who mentioned coding as a use-case? My comment was general and not specific to the coding use-case, and I don't understand where did you get the idea from that I am arguing that building a similarity search engine would be a

Even that doesn't make sense. Why would you not build a vector database to complement your RAG engine?

Perf counters are only indicative of certain performance characteristics at the uarch level but when one improves one or more aspects of it the result does not necessarily positively correlate to the actual measurable performance gains in E

Yes, I understand that. It is implied that there's a high TLB miss rate. However, I'm wondering if the penalty which we can quantify as O(4) memory accesses for 4-level page table, which amounts to ~20 cycles if pages are already

Then it should be pretty easy to display that 20% "faster for free", no? But as always the devil is in the details. I experimented a lot with huge pages, and although in theory you should see the performance boost, the workloads I

I am trying to understand the reason behind why "zeroing got cheaper" circa 2012-2014. Do you have some plausible explanations that you can share? Haswell (2013) doubled the store throughput to 32 bytes/cycle per core, and Sa

What alternatives there are that exist and can replace ROS? I imagine that not all companies are using ROS, however, I'm not in that field exactly so I don't know. I always thought that the quality of that code is mediocre at best

It's not rust per se. It's a human trait. People make uneducated assumptions about the topics all of the time, and it's completely normal since your have to bootstrap yourself somehow to be able to grow further. It's imp

My original assessment wasn't concerned with bare-metal vs sw vs fw at all.

Terrifying. Computer (software) engineering and math seem to be looking like a dead-end professions at the moment.

M4 is 38 TOPS at INT8 precision whereas SpacemiT K3 is 60 TOPS at INT4 precision so at best they would be equal in "AI" performance but they are not because the rest of the K3 chip is much less capable than M4 (as I would expect).

I remember taking down some notes wrt SiFive P870 specs, comparing them to x86_64, and reaching the same conclusion. Narrower core width (4-wide vs 8-wide), lower clock frequency (peaks at 3GHz) and no turbo (?), limited support for vector

Pi runs Linux. That's software. Not bare metal. Bare metal is when you're running without OS, or at light abstraction such as RTOS. Bare metal is normally associated with chips without MMU. Pi runs SoC. I didn't say that GCC

rPi with GCC 4.7 is neither firmware nor bare metal. GCC 4.7 is almost 15 years old.
