It was irony: "new paradigm" is a well known euphemism for "bubble".

Now people is panicking, so it is likely that the sooner you sell, the better.

Is there any reason for the Bitcoin being worth anything? Even in North Korea or Cuba it is easier to hold USD than Bitcoin. I'm sorry for the late investors, but people was warned since long ago.

Sure, it is not a bubble, but a new paradigm... Oh, wait.

TL;DR: Bitcoin is popping, and Ethereum is going to be the new bubble.

Rust has yet to prove that.

Do you know any big code base without bugs? That's not exclusive of C, e.g. check any big Java code base. Regarding Rust, I would like to see the kind od bugs that would arise in big code bases (thread contention, performance issues, e

Sure. And the best "insurance" is having competent programmers.

Yet another subtle pro-Rust rant against C. Programming is hard, and writing safe code requires knowledge, not just in C, but in every single language. Even in formal-validable languages you can make mistakes: may be you'll not make er

C++ sort is faster than qsort mainly because it uses radix sort for integer data in most implementations. You can use radix sort in C, too, e.g. some benchmarks [1] [1] https://github.com/faragon/libsrt/blob/m

I find Rust an ugly and overengineered language. C++ is getting ugly, too, but not that much. In my opinion, C is the simplest and the better for systems programming.

It was until the 19th century, when it was somewhat normalized (census, etc.). Since the 20th century naming in Spain is pretty the same as Mexico and other Spanish speaking countries. All my known relatives names/surnames are without

It was a common practice in Spain until the XIX th century. E.g. Miguel de Cervantes y Saavedra (1547-1616), the author of the book "Don Quixote" used the same pattern (in modern texts is often referenced without the "y"

Before that, in 1930, the Spanish philosopher José Ortega y Gasset (two surnames) published "The Revolt of the Masses" book [1], going even further. [1] https://en.wikipedia.org/wiki/The_Revolt_of_the_Masses

Memory fragmentation can be avoided by construction, e.g. using trees allocated in linear storage (e.g. like std::map is implemented, or the maps in libsrt [1]). For strings a binary tree (or a B/B+ could be faster), and it would not r

Accessing unaligned 64 bit data in 32 bit ARM mode can generate exceptions, even in ARM v8 CPUs when running code in 32 bit mode. Full unaligned memory access for 16/32/64/128 bits is only guaranteed in AArch64 mode, if I rec

PowerPC (and POWER) has reasonable hardware support for unaligned memory access, at least for 32-bit data, and if the data is in the data cache. Depending on the processor, the exceptions that reach the OS can be more or less frequent. ARM

My point was explicitly about C, not C++. All these points are solved in C, decades ago.

E.g. ABI compatibility, multi-platform support, tools, open source code base, community, etc.

by faragon 9y ago
In my opinion, there are more reasons to rewrite Rust code in C.

Why the OS don't prioritize UI threads on one or two cores?

Are you sure C++ is the only thing to blame, and not how you use it?

The filesystem itself is a risk: per-user default permissions so any application launched by one user can trash all his files is scary. Even applications being able to access other installed applications is dangerous. I hope the industry fi

May be the US is doing a wiser thing. I live in Spain, where high speed train was pushed in the era of the housing bubble, and in my opinion is not that big deal, except for communicating the two bigger cities of Spain (Madrid and Barcelona

AMD strategy is very ambitious: attack on desktop, workstation, and server. Can't wait for buying a Ryzen Threadripper (workstation CPU) with up to 16 cores (32 threads), DDR4 quad-channel, and huge L3 cache.

Can't wait for someone claiming the universe is made of Rust (the programming language), and how much better is than being made of C.

Tests are good for detecting code that is not working as expected, using them as a investment/insurance, based on a budget . However, in my opinion, TDD is often more about an obsesive-compulsive religion built on wishful thinking on
