[@oceanfrog]

Poor snowflake had your feelings hurt?

[@TheUltimateGeminiHasSurvived]

Just wondering... why did the word "snowflake" explode right in the beginning of 2018?

[@oceanfrog]

It had exploded well before that. It started as a general insult, around 2008 according to the Urban Dictionary, then became an alt-right insult of leftists (they're all "special snowflakes".) But it turned ironic and hilarious as it turned out the alt-right was as whiny and entitled as they claimed the left was. More so.

@@oceanfrog you don't need a def of "snowflake", just look in mirror dumb fuck.

[@VXIOW_TTV]

@@sparkfx5874 this is a highly stupid comment

[@sparkfx5874]

@@VXIOW_TTV it's highly sarcastic which is pretty obvious. I think at the time some things were going on in the media about white privilege, but for sure I was irritated with conversations I'd had with some of my friends about it. Telling me about my non-existent privilege knowing damn well how I grew up and what little privilege and opportunity there was available to me. Not to mention how I was treated by police and etc. Growing up around New Orleans poor and white and going to a shit school, always struggling, so I was just really frustrated with the whole sentiment as that point of view flat-out negates everything you've done and worked so hard far and reduces it to: "Nope you're white that's why you've obtained even a very moderate level of success." It's absolute garbage and fucking bullshit. What's highly stupid is the assumption that your gender and skin color determine whether or not you can make something of yourself.

This guy's tutorials on JS made me buy a Pluralsight subscription! I do wish he would take better care of himself, he's actively struggling to breath during this presentation and the subtle gasping for air sounds are rather distracting. Hopefully something "clicks" in his mind and he starts practising healthier habits and lives longer so we can all learn from his future contributions to JS!

[@alexnezhynsky9707]

VGM Privilidge is just an idea, just like patriotism and religion. If it supports you in becoming stronger, then embrace it. If all it does is make you weaker and resentful, then ignore it. It is not right or wrong. The right question to ask is, how is it working out for you? The world is a playground of ideas. Choose yours and move along. Don't play the victim game, you don't have to.

[@ssokurenko]

Thanks, really valuable content.

[@MajikSo]

Kyle is an expert in his field and as such deserves tremendous amounts of respect. Unfortunately, he also pushes his own political agenda through the lectures - that's not what professionals are expected to do. Just stay on the damn topic man! You are a hero already. No need push politics into technical lectures! Plus, unlike your technical points, your political points are just your opinions and as such they could be easily fought back with counter-opinions. So, don't.

[@johnn4314]

the privilege talk is reprehensible. but I will still thank you for making education cheap/free for the world. Culture was built on free will. Free will is a privilege the entire western world has. Change black culture, and they will have the same 'privileges' we do. I was educated in complete for 500 dollars in programming. Thats one week at a minimum wage job. Its is up to choice at this point for anyone. period

[@dankwarmouse6248]

It's unfortunate it was built on free will since it doesn't actually exist. The fact you suggest to change 'black culture' to have the same privileges as other groups illustrates this point. The choices you make are a result of your conditioning, so if your environment rewards choices that aren't encouraged or taught by your conditioning, you don't have the same advantage as someone who was conditioned that way. You can't just replace other people's minds with yours and ask why they don't do the things you would do in that position; if you had been born with their brain and lived the same life they had, you would make the same choices they do.

[@johnn4314]

@@dankwarmouse6248 you basically just undermined all moral philosophy, all political philosophy, common sense, and epistemology and human interaction in general. Free will isn't claimed to be understood, but it is claimed to put the burden (or some of it) on the agent who acted. And that's what I think people should stick to

[@dankwarmouse6248]

@@johnn4314 How did I do that? Plenty of philosophers in all those fields share this perspective. Are you suggesting that if you were born with someone else's brain, lived every moment of their life, and had identical brain structure at the moment immediately prior to one of their decisions, you would be capable of making a different decision?

[@johnn4314]

@@dankwarmouse6248 It doesn't matter that many highly educated people undermine it, that doesn't justify their way into the common sense compartment. The point you need to think about (kindly) is the fact that you added the sentence "..identical brain structure at the moment immediately prior to one of the decisions". This is the only point that really matters when determining if such a thing called responsibility can exist. The other parts are good too, but merely toward the argument that there is some qualitative amount of grace that should be given to bad decision makers. It's a reduction to absurdity if you can't accept the premise that nothing is what we think (or convey) it is.

[@dankwarmouse6248]

@@johnn4314 It matters if you're planning to cite all these fields as though they are united in some kind of free will certainty. The point seems to have shifted from free will being self-evident to free will being a convenient framework to determine responsibility. I'm curious what your reasoning would be beyond that, and would offer you to consider that if your definition of responsibility requires free will to exist, it shouldn't be surprising that it seems incompatible with deterministic world views. Also, and I mean this kindly too, unless you can illustrate what my sentence is meant to have reduced to absurdity, I'll remain pretty comfortable in my position. It's not as though I haven't thought deeply about this and read plenty of primary source literature from philosophers spanning thousands of years, as it was part of my degree. Despite free will's mainstream popularity in Western philosophy for the majority of history, I've yet to encounter any model -- other than the more cynical solution to Kant's Critique -- that doesn't have internal inconsistencies, depend upon responsibility as some axiomatic qualification for moral culpability, or essentially boil down to "it feels like we have it."

He's highly knowledgeable on JS, but the SJW stuff was ridiculous. I double girls applying for a Developer job are being measure against a much higher standard than guys. It doesn't matter how much effort each person has to put in to get to a certain level as long as it's the same level. It's also absurd to expect people to be equals. Khmer Rouge tried this; didn't turn out well. And what is wrong of expecting of someone of having to work harder. The work is the reward. Having low expectation of someone is much more detrimental to them. Stick with just JS Kyle.

[@jeremyashcraft2053]

Cringed so hard when he began moral grandstanding about inclusivity. I love tech as an industry, but I'm so irritated by the culture of virtue signaling that is so prevalent in tech. It's as if people feel they need to hold certain opinions so they can be included in the tech world.

[@redrowolloftnod5230]

It's easier to reason about regular callbacks than all this shit he's talking about. The "next level" is to dump this overly confusing nonsense and learn Elixir or some new language that moves away from the mistakes of JS. Kyle's teaching style has become like the "Bridge to total freedom" in Scientology. "What I really want to talk about is the next next next next level....!"

[@canadianbootz]

Stop trolling. If you're serious, then I suggest challenging yourself to understand this "complexity". I did, and I'm now a better programmer for it. Kyle's closing remark nailed it on the head.

[@andurilan]

Hes not wrong, fellow canuck. JS/ECS stumbled into dominance by quirks of history, not because of it accessibility or breadth. The language is a ragged patchwork quilt of bad, rushed design decisions, overcorrections, design by an indeterminate committee and vulture culturalism. As an example, I recently took up a hobby project in AS3 for some much needed rest from ES6/7/babel, and was surprised to find how much of it had been picked over and apart by the consortium for ES6 and 7. And for what, so that iPhones can run apps that run well enough but all look and behave the same as boring flat web apps? His comment about dogma within the community is quite on point. Its not trolling just because you disagree with him.

[@canadianbootz]

There is dogma in every community, so it's irrelevant. "dump this overly confusing nonsense and learn Elixir or some new language" etc. is trolling in this post's context. redro is entitled to his opinions of course. But further saying "Kyle's teaching style has become like the "Bridge to total freedom" in Scientology." puts a final nail in the coffin he made for himself. He's really just embarrassing himself and Elixir, and I hope he understands that now. I have nothing against Elixir either. Every decent tool has it's strengths and weaknesses.
