Seems like if people want to do harm they will find a way. Buy guns and start shooting up a crowd, buy a car and run people over...
Apart from Snowden most of the leaks have been CIA/NSA staff just leaving their malware and sourcecode lying around on staging servers for anyone who finds them to pilfer.
Is this something that normally happens here...a person willfully misinterprets another's argument, then advances points that have little or nothing to do with what was actually being discussed?
Not just here, it's everywhere now. Instead of having debates people just re-frame and start spooling out their standard talking points.
I think a lot of them aren't even aware they are doing it, they are just copying people they see making successful "arguments".
What do you think NK is doing to the US right now?
They keep baiting Trump, knowing that he will be unable to resist responding with a tweet or vague threat, which only makes him look even less capable of actually doing anything to improve the situation and strengthens Un's position as a player on the world stage.
I've read North Korea doesn't even have computers.
Have you noticed how when you see North Korean TV news boardcasts in the west they are low quality analogue 4:3 images? Because NK only has 1960s level technology, right?
On NHK news broadcasts in Japan they show the full HD 1080i satellite feeds that NK transmits.
I'm not disputing that there is a gap, merely disputing what it is that the IQ test actually measures. And the genetic component seems to be very small, and the evidence for it is not very compelling since it is impossible to control for other factors.
What kind of craptacular "rugged" laptops are you using? I've been using Thinkpads and Toughbooks in -18C conditions without issue. Well, my fingers not being able to type my password was an issue, but the keyboard was fine.

The curved surfaces help your fingers auto-centre. As you type your fingers can feel how far off centre they are and your brain makes corrections, resulting in fewer errors. With flat keys there is less tactile feedback on finger positioning.
Really, so when these MIT researchers write "Unfortunately, the rules for what is undefined behavior are subtle" and "tricky", you think they're just idiots?
Those two statements are not contradictory. I'd question their description of them as subtle and tricky though... I guess, kinda, if you don't know about them.
I use Rust as much as possible now, and it can target 8-bit microcontrollers
I am going to have to spend more time playing with Rust.
By that logic the 100m sprint isn't a measure of who can run fastest.
It isn't. It's a measure of who can sprint over short distances fastest. Using it as a measure of general running performance clearly disadvantages distance runners who are not fast but have exception endurance.
better nutrition? Less pollution?... It says nothing about it one way or the other. Completely irrelevant.

No, it's just that optimizing assembler requires a detailed understanding of the operation of the CPU. Back in the day we had tables of instructions with execution times, memory access requirements and the like. As machines developed it got harder, you had to consider DMA memory cycles for other hardware, then caching, burst accesses, pipelining etc.
Once you get to large, multi level data and instruction caches, plus out of order superscalar execution, and a large variety of them, it becomes very hard for a human to handle. There are exceptions, the most common being vector instructions. But competing with a compiler that has a model of a complex CPU is pretty hard.
I kind of agree that the gap needs to be addressed, I'm just not in agreement about what the gap represents. For example, in the 1930s white Americans were 20 points below today's level. That is, the average white American from the 30s is equivalent to a modern American who dropped out of school before age 8.
Sure, but success is not the same thing as intelligence. And success is strongly correlated with wealth and access to good schooling (although there are plenty of exceptions), which suggests that IQ is not measuring some kind of innate ability or mental processing limit.
I'm not suggesting that IQ doesn't measure anything. I'm saying it measures a variety of non-fixed things. I guess you could compare it to CPU benchmarking, which as we know often has little relation to real world performance and if often artificially inflated or reduced by external or largely irrelevant factors, like small variations in RAM speed.
So what are you claiming it actually measures? Performance at certain tasks that may or may not be biased towards one or more cultures, which require some degree of practice to reach full potential at?
That doesn't sound like a general measure of human intelligence.
And how do you explain the Flynn effect, which if you don't know is the fact that IQ test scores have been rising by an average of 3 points per decade since the early 20th century. Using today's scoring standard the average IQ of the United States in 1932 was 80, a level typically associated with elementary school drop-outs. That little fact also blows up the racial intelligence theory too.
Indeed, and your score can easily be improved with practice which means it can't be a measure of raw intelligence unless practicing IQ tests is also the most effective way to boost your innate intelligence.
Some people just want to believe that there is a scientific, objective way to measure a person's worth. They usually think they are near the top of the ranking, especially if they also cling to the idea of racial intelligence.
But just for the the record, Assembler gives you better performance than C and C++.
Eeehh... kinda. A skilled assembler programmer can usually out-optimize the compiler over smaller sections of code and simplistic, but on larger projects or complex CPUs the compiler usually wins. For example, most modern CPUs are superscalar, pipelined, do out-of-order execution and have large caches. It's pretty difficult for a human to optimize code for those things better than a good compiler can.
On microcontrollers it's a different story of course.
insane preprocessor, no module system or namespaces, all kinds of obscure undefined behaviors, no way to express important safety properties like "pointer is never null", weak type system that can't express tagged unions or tell the difference between data and code pointers (https://lkml.org/lkml/2017/9/25/708), broken type syntax where it's impossible for humans to write complex types, security-bug-prone standard library APIs like sprintf and strcpy, standard library missing basic stuff like hash tables, inability to expose basic library features like ref-counted pointers and growable arrays ergonomically,...
No offence but I can tell you are not a C programmer.
The great thing about C is that you can fully understand every aspect of it. It's not like C++ where it's overly complex to the point that few people know all its features and behaviours. In C with a few years of experience and study you can know everything there is to know.
There are no obscure undefined behaviours, only well documented ones. You can easily express that pointers should not be null through asserts and common extensions (e.g. GNU's __attribute("no-null")). C supports unions, and it's weak type system is what makes it great for low level development - you just have to get into the mindset of data being bits and bytes, not some abstract and opaque box.
The standard libraries are a bit crap, I'll give you that. There are things like Boost if you want more, but the lack of things like hash tables in the base language is because those things would make it hard to port and run on low resource systems.
I think you using the wrong tool for the job. C isn't designed to do those things you talk about, because they come with overhead and C is a system programming language. Any "replacement" for C is going to have to work in environments with memory measured in bytes. It's going to have to support stuff like full static allocation. What you want is something more like C# or Java.

More interesting (to me) is this offer to upload data to the satellite.
Do they check the data before it is sent? I hope so, otherwise they are going to be the first to host a bunch of 4chan memes and child porn in space.

We agree. They should remove the I from IQ.
Until your boss thinks your skin colour correlates with your innate intelligence.
You keep saying IQ is correlated with various things... But not intelligence.
So you are saying it's a test of aptitude in various disciplines... I agree, but that's not how some people treat it.
Sure, but success is not the same thing as intelligence. And success is strongly correlated with wealth and access to good schooling (although there are plenty of exceptions), which suggests that IQ is not measuring some kind of innate ability or mental processing limit.
