i-am-curious··on Mathematicians should stop naming things after each other
Now this is most certainly wrong. Example (search "history research"):

"Research in history involves developing an understanding of the past through the examination and interpretation of evidence. Evidence may exist in the form of texts, physical remains of historic sites, recorded data, pictures, maps, artifacts, and so on."

i-am-curious··on We didn't encrypt your password, we hashed it
Yes I meant salt! AFAIK such a fast cracking of hashes is mostly via rainbow tables, salts defeat those easily.
i-am-curious··on We built a video conferencing app using JavaScript in hours
But why would you not combine them? In fact, I can easily see people being lazy and combining just on N sized stream to reduce server overhead especially if there is compression on top.
i-am-curious··on We didn't encrypt your password, we hashed it
Won't you add a seed before hashing. With a 8 byte seed that's 16 effective characters, probably impossible to crack.
i-am-curious··on The problem with C
Doesn't LTO interfere with debugging massively?
i-am-curious··on We built a video conferencing app using JavaScript in hours
P2P scales quadratically, central server scales linearly. You might argue the cost is not borne by the operator but imagine what happens if Zoom was P2P. It would probably bring down the internet.

Moreover P2P would require more upload bandwidth per user from users. P2P just doesn't make sense for standard video conferencing.

i-am-curious··on Fusion is not 20 years in the future.It’s 50 years in the past–and we missed it
That's 1 cubic meter. We have a lot more seawater?
i-am-curious··on Facebook prohibits music or music listening experience on Live
Except that the instances you listed are not a problem the vast majority of the time. While copyrights and patents are enforceable for any unauthorized use no one would bother until you are rolling in the dough, at which point the laws make perfect sense.

That said, I am not arguing that patent law doesn't need reform, especially patents for software, algorithms and math.

i-am-curious··on GPT-3 pricing for API usage announced to beta users to go in effect from October
I feel like the best way to filter spam is using information content. As it turns out, nobody is handing out $1,000,000 for free no matter how nicely they write the email.
i-am-curious··on The problem with C
> I don't see modern application of C outside embedded,

C is one of the most popular languages for high-performance code. Most famous example would be the Linux kernel but literally anything that needs the best optimizations possible eventually comes down to C.

i-am-curious··on Kubernetes: Make your services faster by removing CPU limits
Isn't the solution painfully obvious. Remove the limits around the time you expect extreme loads. Like you said, it works most of the time. Take a hit for unexpected workload spikes. It's a design decision.
i-am-curious··on Nvidia Unveils GeForce RTX 30 Series GPUs
This is a misleading comparison. You are comparing a massive model with huge models. What you should be comparing are big models vs medium models that a single consumer GPU will fit. And - you don't need to take my word for it, there's tons of papers - the bigger models definitely perform better.
i-am-curious··on Nvidia Unveils GeForce RTX 30 Series GPUs
This is such a simpleton take.

The whole reason AMD are able to crank out 128 core CPUs is the CCX architecture - the one people laughed at. No TSMC there. Not to mention other innovations like Infinity Fabric.

In ampere for instance, there are so many innovations, like PAM signalling, 2x shader instructions per clock, DLSS, RTX Voice.

TSMC beat Intel, sure, but that is not the main reason for why Nvidia and even AMD are leading the industry. In fact, ampere is on Samsung 8n.

i-am-curious··on Nvidia Unveils GeForce RTX 30 Series GPUs
Forests have pretty much been solved. Look at games like Shadow of the Tomb Raider, forest looks amazing. The difficulty now is limited to finer details, like hair. Hair is still pretty much unsolved.
i-am-curious··on Nvidia Unveils GeForce RTX 30 Series GPUs
Not at all. The 20 series has excellent founders cards.
i-am-curious··on Do we really travel through time with the speed of light?
Of course not. We can prove things that are absolutely true. For example, we can show 2+2, with suitable definitions of 2, + and 4, always equals 4 anywhere in the universe.
i-am-curious··on Impact of Go AI on the professional Go world
What's the incentive to master a game already beaten by AI?
i-am-curious··on Show HN: 3D first person game rendered in CSS/HTML
Agreeed. I finished the game on mobile ;) Though the story could use some work !
i-am-curious··on TSMC and Graphcore Prepare for AI Acceleration on 3nm
This is unfortunately prevelant on most discussion forums. In many cases this correction is downvoted and buried deep.
i-am-curious··on Why Epic can’t afford to lose the Unreal Engine in its fight with Apple
They would allow Fortnite back too.
i-am-curious··on SSH Keygen – RSA, DSA, Ecdsa, EdDSA
> This principle is what allows the SSH protocol to authenticate identity.

This part is also confusing. I feel like it is important to clarify that identity is not "established" using cryptography, rather verified. When Bob claims to be the Bob, you don't know and can't know just from this claim if Bob is indeed the Bob. To verify that this Bob is indeed the Bob, you have him certify from someone else that you trust that he is indeed the Bob (or you just certify it yourself when your computer asks you to trust a new fingerprint).

i-am-curious··on Problem Solving with Algorithms and Data Structures [pdf]
> Does not a double ended queue have O(1) enqueue and dequeue?

Yes. It's a basic data structure implementable using vector or linked lists.

When using the linked list, you can even do erase in O(1) assuming you have the pointer already. This also turns out to be super useful

> Auditing code that you don't have the source to is like an order of magnitude harder.

If you don't have code you can't audit code!

i-am-curious··on Btrfs Coming to Fedora 33
Doesn't gparted do this for you? It will automatically figure even the most complex of operations that require filesystem copy.
i-am-curious··on Challenge to scientists: does your ten-year-old code still run?
And any such "research" should go in the bin. Reproducibility of final results a me d their review is key.
i-am-curious··on Natural language benchmarks don’t measure AI models’ general knowledge well
> To make the neuron network be a strong AI, we may need the parameters in scales of 10^19~10^44 (uncertainty limit and Planck time) estimated from how many frames per second in real world.

There is absolutely no basis for claiming this. It might turn out that there are better algorithms for AI than neural nets. Do you even realize just how many parameters even 10^12 is???

i-am-curious··on Natural language benchmarks don’t measure AI models’ general knowledge well
It's amazing just how many people believe that neural networks have a close resemblance to the human brain.
i-am-curious··on Semi-transparent solar panels allow concurrent production of crops and power
Nope. If the bag looks blue that means it's scattering away blue light while letting the rest through. So it's filtering (out) the blue. OP is right.
