Agner's table[1] for Intel IceLake/TigerLake shows FDIV to have higher latency, but slightly better throughput. For latency: - DIV/IDIV r32: 12 cycles - DIV/IDIV r64: 15 cycles - FDIV: 14–16 cycles Throughput: - DIV&#x2F

Publishing a zero knowledge proof rather than the solution is pretty clever.

If I would like to build a visualization like this, but for a data ingestion pipeline, any tips on where to start? I have it visually in my head, but it feels overwhelming getting it into a website.

PHP loads all available functions into a giant hashset (see zend_disable_function in PHP's source). 'disable_functions' removes the functions from the hashset, making them unavailable to be called. Due to its interpreted natu

Are you saying that two weak factors are more secure than one strong factor?

I agree with this. As someone who took 3 degrees in computer science, one called "systems developer" and another called "software engineer", I can confidently say we have a taxonomy problem in computer science education.

Thanks! The direct hooking into the narrow phase solver is the most performant way to go about it, but it does present several issues in state management. I did the same thing in Farseer Physics Engine, but also added high level events on b

Wow. That is actually very impressive. Things have moved quite a lot since I did a physics engine. What makes it difficult to integrate?

That's a bit disingenuous. Can you substantiate your claims?

The security of the Apple ecosystem is miles ahead of others. Every time I reverse engineer some component of their OS, it is very different from what I've seen before. I always find myself surprised by their thoughtfulness and enginee

The condition is called Anosmia and can stem from different sensor and brain conditions. It would be interesting to try the technique on people with these conditions to map the different kinds of olfactory failures. If you get in contact wi

It is also kinda a self-burn. Chromium an aging code base [1]. It is written in a memory unsafe language (C++), calls hundreds of outdated & vulnerable libraries [2] and has hundreds of high severity vulnerabilities [3]. People in glass

I generally agree. However, there are several important optimizations that Roslyn does not yet have. I love the improvements in newer versions of the compiler as much as the next guy, but historically, waiting 20 years on getting basic inli

Taking a bunch of data from the Korean National Health Insurance database and looking for one specific connection is less than helpful. Like carl sagan said: extraordinary claims require extraordinary evidence. A significant error I often s

It looks like a process model; isolation between programs with a system for inter-process communication, and running within a single process's memory. If I understand correctly, instead of writing a c++ application to offload the compu

C# started as a language tightly aligned with C++/Java, but has since moved to be something else entirely that is highly capable. I assume that free-floating functions are global functions. You can achieve something similar by "gl

Do you have any regrets about an algorithm/data structure and wish you picked something else?

It isn't. You cannot derive an arbitrary length key with bcrypt.

For those reviewing the changeset: There are two places where they read a value directly from $POST into an $args array. There is no validation applied, which means an attacker can inject whatever value they wish.

We are saying the same thing. H0 is SHA-1 in your example. The strength of an HMAC depends on the strength of the hash function; however, since it uses two derived keys, the outer hash protects the inner hash (using the same hash function),

by Genbox 2y ago
You are making two assumptions here: 1. More hash functions equals more security (hash encapsulation) 2. The attacker wants to know the content of 'm' H0(H1(m)) has the security of just H0. Hashes are not made to protect the conte
