I've never been able to fix the tool calling issues. Running unsloth versions with llama.cpp, constant issues. Have tried many forum fixes, including lots of fixed chat templates, …

All ALU operations are also more expensive with 32 bit operands. So 16 bit data bus, 24 bit address bus. Slower arithmetic with 32 bit operands. I never though of it as a 32 bit CP…

I'm a believer in restricting the scope of definitions as much as possible, and like programming languages that allows creating local bindings for creating another. For example: lo…

Steam on Linux works really well now. I sort of built my own steam machine a few months back with a framework desktop that now sits in my TV rack. Gaming on it is a really good exp…

CMake has become the defacto standard in many ways, but I don't think it's that easy to deal with. There's often some custom support code in a project (just as with make files) tha…

I don't see the point of passing the size to a "free" function. I don't see how it could be used to speed up de-allocation. Additionally most usage would probably not want to keep …

I actually did at one time, and it was fantastic. Then Agile was rolled out in that organization and ruined everything. Oh, the irony.

Hmm, I was a hang around back in the day. Not one of the big boys. But I got to say some of the young kids that I hung around with then had more skills than many I've worked with i…

- Multiple out file dependencies are also difficult to describe in make (GNU Make). There's a dedicated section for how to solve it in the manual[^1] but it's a crutch. - Taking en…

Perhaps this is similar to how they work in go? "var x []int; fmt.Printf(`%p %d`, x, len(x))" outputs "0x0 0" Indexing "x[0]" results in: "panic: runtime error: index out of range …

I think most applications don't have any dependency towards a specific page size. They use malloc (C) or new (C++) to allocate memory which does not expose this constraint. You nee…

Can the CPU cores in a CCD access the L3 cache of another CCD with higher latency? If so the CCD without extra cache may still get a performance boost. I know there has been such d…

There are many contradicting examples: The original JPEG standard is an ISO standard (ISO/IEC 10918) with payed access. MP3 is also an ISO standard (ISO/IEC 13818-3). Perhaps not a…

Nitpicking on terminology. Portable used to mean that software can run on another platform with minimal modifications. Typically by relying on abstraction layers that then has mult…

I think a mindset that could work is to accept software as done. This is hard but for foundational stuff it could work well. Only fix bugs in such software. Try to set a scope what…

So Go has two GC knobs now. I think it still plays to the ethos of minimalism and restraint.

ASAN is pretty great with these cases as well. Spent much time looking for the needle in the haystack before ASAN came along.

Go 1.0 was released in 2012, it spent 3 years in alpha/beta phase. https://go.dev/blog/go1

In my experience debuggers handles this fine. Some archs also has a link register (jump and link) which may help finding back. This test is from x86-64 Linux. /* gcc -g -Wall -o x …

Yes, you are correct. I had not thought about it deeply. There are restrictions for what can be used as a map keys according to some built-in equality rules. And of course the type…

Built-in map and vector types are generic. E.g. map[int]*MyType Using interface{} is quite common in the absence of sum types (or inheritance with base class). I guess interface{} …

RISC-V really is the heir of MIPS as it had those TLB tags as well.

The compiler is fast in that is compiles code quickly, just as Go and the execution speed of produced programs are similar to Go (depending on what abstractions you use). It seems …

Not weird but I can share what has worked for me so far. I'm pretty skinny but like to eat junk food and candy. My target weight is 80-82 kg. When I hit 90 kg I don't feel good abo…

Well yes, I was one of the haters back then because it was too verbose (for me). IMHO Go is less verbose than early Java. It could be less verbose without loosing readability. My t…
