I definitely agree that it would be better if LLVM has a more flattened learning curve and a more accessible manual. I'm only pointing out that many "problems" listed in the post are intentional design choices for good reason

Not LLVM expert, but I don't agree with some of your arguments. > My side of the code generator had to recognize when a variable had already been defined and keep track of its pointer For human, it's natural to write code text

This is the best story I've read in a while. No idea what fraction of her words are truth, but it's sad that such charisma is only used to build a fraudulent product in the end, instead of making the world a better place.

If what you said is true, honestly this is beyond imagination. Can't imagine what's gonna happen if they had a data leak..

Please correct me if I'm wrong, but I vaguely recalled Plaid actually directed me to my bank's webpage and asked me to input my username and password. So it seemed to me that it's similar to those "log in via your Goog

Well, in that case, the language barrier is already putting you behind a selective information filter. I'm not trying to convince you (in fact, I'll be happy if you could point out why I'm wrong), but I do not pay much attent

(Disclaimer: I am PRC citizen currently in US) I think it is very hard to get a "detached analysis". For politic issues like this, it is inevitable that everything you read will be both incomprehensive and biased, and filled with

Yes, it's a tradeoff. The upside is now you can put the object on the stack without invoking memory allocators.

Thanks for clarification. It's nice to know that this approach is fully standard compliant. (and that's exactly my point: the standard is hard to access for normal devs like me, so I can guess "some reinterpret_cast hack seem

After the object is constructed by placement-new, the class methods still needs to reinterpret_cast the char array to an object pointer to access the object. I don't think in this specific case there is an UB involved, but I'm not

Yes, strict aliasing (or type-based alias analysis?) is quite crazy, and there are some murky dark corners where the specification is different between C and C++.. I think they have a std::launder thing exactly for this purpose of "saf

Thanks for the explanation! When I read the article, I felt the last step is much more complex than it is said. It seems like you confirmed this point. I will be very excited to see a post on how these aesthetic improvements are made!

This is a well-known way to achieve separation of definition and implementation. The disadvantage of the method proposed in the article is that, now everything needs a pointer indirection. A solution that fixes the drawback is used by lz4&#

LuaJIT's interpreter loop is similar, except that it's written in assembly, and the motivation is that the compiler could not optimize the C version to the best possible extent. Kind of related, this post [1] mentioned some ideas

Can you elaborate a bit more? I don't know how I can refute his concern (of course I'm not in the field though). It seems true that if Prop 22 were passed, he would have to become an employee for one company, so he wouldn't b

I feel it hard to understand the truth with so much propaganda from Uber and Lyft that muddies the water. That said, once I took a Uber ride and the driver strongly urged me to support Prop 22. According to him, he (and most of the drivers)

As the article said, "this is structural racism". Interestingly, the models did not do anything wrong. They are only trying to predict the future based on the past. The colored groups have been discriminated and tend to have less

Very interesting article. The discussion on the three models and their own deficiencies are quite interesting. Niche assembly: every survival must have its own unique edge of advantage. I guess I'm most convinced by this. The counter-a

As someone who don't know how to use Photoshop, it's interesting to learn (as you said) that, most the difference is only contrast and saturation. The final image just looked so much better than the second last one for me.

It seems like the last "Improving the color" step is what gives most of the atheistic effects (by comparing the second last picture and the final result on the top). Unfortunately the explanation for that step is only a few senten

OK, thanks for replying every comment to defend CookUnity. 1. The point is not about subscription. It is about they only send email after it's impossible to cancel orders. This is clearly a ill-intended behavior. And no, I did not re

I did not realize it was a subscription, and I was expecting that even if it was a subscription, I wouldn't be charged since this subscription contains action items (the food item to buy), or at least I will have a chance to cancel. Wh
