I am sorry, but how is this new and why is this scary? The article doesn't make a case for this being genuinely scary.

The author may have a valid point or two, but at the end of the day, it's not that big of a deal. Everyone over promotes their products because it is in their interest to do so.

> Evangelism is considered harmful as an organizational technology.

Ok, I don't disagree there.

> Second, evangelism suppresses dissent

Good point.

But still, it's not a big deal.

I am assuming game developers are interested in the applications of Linear Algebra and there are many other books that are far suited for that.

Anyone from game dev community care to elaborate ?

Since it doesn't neglect computation, it's great as an introductory text.

After that, and some other math courses you can move on to Linear Algebra Done Right.

If you are looking for replacement erasers for your autopoint pencil (the slim one), these fit perfectly and come in various colors: https://www.build-a-pencil.com/collections/all

I had heard rumors somewhere that someone bought the rights and the machines but that’s about it!

I’m surely going to buy a few!

Thank you so much!

I am going to be very very pedantic here so read on for entertain purposes....

I don't like the unusual shape of blackwing pencils' erasers. They break the symmetry of the entire pencil.

However, I like dixon ticonderoga the most since they are a good balance of quality and price.

But, I usually use mechanical pencils. And I am very particular about which kinds to use.

My favorite overall is "Autopoint". This company has been out of business for many years, perhaps decades so I only have a "vintage" collection of those which I use regularly.

This is what they look like: https://www.newegg.com/autopoint-inc-all-american-ink-lead-r...

Here is my criteria for a perfect (to me) mechanical pencil: - retractable tip/nib - always exposed eraser (there should be no cap etc.) - replaceable eraser (should be as thick as eraser at back of wooden pencils) - no fancy buttons - pocket clip

The best mechanical pencil I have tried that feels just right and is balanced, is P209. However, it doesn't have a retractable tip and the eraser is not exposed. If it did have retractable tip. I wish it did.

The one that really comes close is Faber-Castell grip matic 0.7mm. It is almost perfect! It has retractable nib, and an always exposed eraser which also retracts! And a great grip!

Alas, it has two problems: the eraser is twist up type which is fine, but when you erase with it, it twists and retracts back inside. Also the eraser encasing is a flimsy plastic that gets loose over time. Ugh! You were so close!!!

I was alluding to the current mix of the content on reddit. It has gotten more political and less entertaining if you look at the default feed whether you create an account or browse anonymously.

And in any political or open ended discussion, unless it is scientific, the discussions are shallow.

I will however concede that non-scientific/technical discussions were always shallow.

Unless it's a niche and technical subreddit such as mathematical topics, bio science subtopic, the discussion is quite shallow and in some cases simply misinformed.

For e.g., a recent question about "is this person racist?", everyone jumped on the bandwagon and said "yes!", "100%", "obviously" without citing any sources. They simply paraphrased a small segment of a video of what that person said.

It turned out the thing they paraphrased it was completely out of context and in fact proved it was opposite of what people were believing.

There were a couple of people who pointed this out but they were downvoted into obvilion: -50 downvotes or something like that.

So these comments were hidden by default.

This is what makes reddit an ecochamber. Now just imagine people coming in and reading this post without any prior knowledge, and taking away the wrong conclusion.

This happens ALL the time.

I used to enjoy reddit back in 2011-2013 when it was all about silly memes and jokes.

EDIT: "They simply paraphrased it" --> "They simply paraphrased a small segment of a video of what that person said."

Seriously, what's going on there ? Why is it so different from others? Is it just behind technologically/training wise or it's using something fundamentally different?

Yikes! No.

I mean even for the intents and purposes of using this definition in ML, this might not be right.

I am trying not to be pedantic, so I will not go with the official/mathematical definition of a tensor as that could be incredibly confusing (look it up!!!).

But a tensor is a LOT more than that. Essentially it's a multilinear map that transforms a set of basis vectors in a certain way, and is coordinate agnostic.

This is not even half its definition so you can see how much the author left out.

Having said that, this is still a good way to start getting intuition into it and I urge the author to continue refining the definition as he/she learns more.

Disclaimer: MS in Math with concentration of GR.

EDIT: Also tensor aren't simply "flat" array of numbers. They are multidimensional. A grounded example, a rank 3 tensor is a collection of 2d matrices. Think of it as a bunch of 2d matrices stacked on top of each other. You need 3 indices to keep track of numbers --- sure in a programming language, it can be represented as a 1d array as well with 0s filling up empty spaces, but you get the idea.

By contemporary lesson I assume she means similar lesson but more recent and keeping modern world/logistics in mind.

One of my favorite use cases is talking with it while driving on random topics and learning about them.

$240 (non member price) for a 5 hour course.

Did I read that right? Or is it more 5 hours of instructional videos?

Either way, it doesn't seem to include grading or other help etc.

The "vocabulary resolution being low" basically just means within our own limited context, it's low. But that doesn't mean it's a good measure. Heck, I'd say it isn't.

What I mean by that is we'll have a very limited number of words to which a dog's brainwaves can be translated to since we aren't able to understand them beyond their basic instincts of food, survival, fear, affection towards their owner etc.

There is just no way to go past what we have already observed by their behavior since dogs can't talk or write.

I do wonder how animals think. Perhaps this resolution would also be the theoretical maximum?
