It's a weakly-typed language that is rooted in the typeless, machine-word-oriented nature of BCPL. The "char" type in the early implementation for PDP-11 was just a feature to benefit from the byte-addressing capabilities of

This is one of the most delusional and speculative books I've ever read. The author comes up with elaborate analytical models resting on slippery, loosely-defined terms. Being smart with algebra while totally disconnected from technolo

It looks like some cool new kids are rediscovering it, after more than a decade of pythonisation and javascriptisation of programming. You can have things that behave like values and actually reside on the stack, you can ask the operating s

As someone who is familiar with the political and social atmosphere in the country, I'll give it a try. The growing adoption of "Latin-based culture" is not interfering with the usage of Bulgarian. Bilinguality is the norm fo

In the longer term, too many unpredictable factors can collide, so anything is possible. Particularly in Bulgaria, the youth is dominated by western culture only at the surface level. It’s in their consumption patterns, the outfit and the s

There’s a new wave of nationalism emerging in Bulgaria. Any interference with the national identity would be seen as blasphemy, done by foreign agents paid by the “embassy”.

Looks like a solution in search of a problem. Given the weakly-typed nature of C, how can this ever be reliable? In an expression like “x = y”, the operands can differ in size and signedness. The inferred types can be wrong and the resultin

It’s an essential part of the Unix process model. The whole design feels dated and centered around shells and terminals. A more productive endeavour would be to propose a new design without all these warts. Not cherry-picking and whining ab

Pretentious title with little substance to justify the claim. The inherited signal disposition mask with the blocked signals can be restored in a forked child process, before an exec. Because it makes a shell-spawning function like system()

Pointers to arrays are an incredibly rare thing in real-world C programming, let alone functions returning them. They contain the same address as a pointer to the beginning of that array, with the only difference that pointer arithmetic wil

Stuff like memory pools, arena and slab allocators have been in widespread use in C/C++ systems programming for decades. It looks like designers of hip languages are reinventing that stuff in compilers that try to protect you from your

It can be the studying of past ideas that have deeply influenced the cultural, societal, political and scientific norms. Something as fundamental as Cartesian epistemology characterises much of the Enlightenment and its values. It's a

The interpreter is linked to a cross-platform libc-like library, and compiled to a funky executable format, supporting multiple OS targets simultaneously. The initialisation and startup are probably computationally-intensive.

Polymorphism is doable in plain old C with lookup tables and function pointers. If that is the only benefit, what is the point of creating a language where everything is an object?

In the 1990s, it coincided with the proliferation of GUIs and their respective programming interfaces. Most frameworks use hierarchies like Object->View->Control->Button->ImageButton. Then people decided that this is the way for

The name doesn't matter that much. In essence, it is centralised wealth extraction on a mass scale. The "rent" extracted is disproportional to the value of the service and their operational costs.
