This makes no sense. They ran the tests from a “neutral cloud provider”, as if someone is using AWS S3 to store their Azure and GCP data?? And they didn’t explain where exactly Tigris was running or how they controlled for the network latency. AWS is insanely faster when the compute is in the same region as the storage. They also didn’t mention what class of S3 they used or what replication settings (eg. S3 has express one zone).

I’m all for benchmarking and showing that your product is better from a technical standpoint. But at least for me, this is not the way.

Agree. There are literally zero takeaways from this article other than it being a marketing post.

It's literally just sticking the MPs name into an AI and asking for it to generate a mock ID for them. None of their real data is being used (e.g. their face, their DoB, the address) and the mock IDs wouldn't fool anyone for a second. I'd love if someone who understands the law would weigh in though

It's better to be safe than sorry. For your own best interest, I would shut down the site and delete this post.

if (!isShakerRunning) { sendAlert() }

seems like a pretty obvious thing to add

Doesn't seem that obvious to me

What if exploding nukes on the seafloor has the opposite effect and actually _releases_ already sequestered carbon?

IMO, this idea is very poorly thought out.

>> If I'm taking multiple hard courses, I only have so much time to spend.

You’re in high school. No course is hard.

>> Free and competitive markets are more efficient than command economies. Arguably, this same principle holds true on an individual level.

This is a silly statement. Free and competitive markets are not always more efficient than command economies, and they certainly aren’t as you move away from a market to a market unit. So, no, your erroneous principle does not arguably hold true on an individual basis. There is a reason that corporations are structured more like a command economy than a free market.

I respectfully disagree :)

Not only do my peers and I find many of these courses challenging, but AP classes are widely recognized as college-level coursework taken in high school. I will have completed 17 of them by the time I graduate.

That said, my argument doesn't depend at all on whether these classes meet your standards for being "hard." Even if you believe you'd ace them with flying colors, they're still time-consuming and rigorous for most high school students. Focusing on semantics about the word "hard" instead of the point I'm making suggests there's little substance to your rebuttal.

Finally, if no course is hard, as you claim, why is note-taking even necessary?

How is your learning harmed? How have you been disallowed from discovering what works best for you?

> How is your learning harmed?

One's goal when studying is to optimize learning as a function of time. When note-taking is forced, this goal becomes impossible for me. I spend time taking notes when I could be spending time on more impactful study techniques (videos, practice sets, etc). To be clear, I think the notion that "notes are useless" only applies to specific groups of people. The bottom line is that everyone learns differently, and forcing a certain approach is an awful idea.

> How have you been disallowed from discovering what works best for you?

I would not say that I have been directly "disallowed," but undeniably, there are bandwidth constraints for students. If I'm taking multiple hard courses, I only have so much time to spend. If I am spending my time note-taking, which my teacher requires to turn in to him/her, then I have less time to do other, more productive things with my time. I think naturally, freedom spurs efficiency. Free and competitive markets are more efficient than command economies. Arguably, this same principle holds true on an individual level.

That’s quite impressive, care to share what does work for you?

I'm huge on videos + practice sets.

Khan Academy has been such a lifesaver. They not only have in-depth videos, but also have practice sets after every lesson.

AP Classroom (a platform made by College Board) is also amazing. They have videos and progress checks.

Generally, it is true that writing by hand is better for recall and memory. However, teachers often use this as a justification to force students to handwrite everything, which can be very counterproductive for a subset of students.

I am currently in high school and have taken 17 AP classes. I have tried taking notes time and time again and have consistently found that they do not help me at all. I have a 3.99 GPA, 1570/1600 SAT, and have received 5s on all of my AP Exams. I know how to study and know what works best for me. I am not a notes person, and when teachers force their "scientific" teaching methods upon me, it does nothing but harm my learning and waste time.

I love the idea of science being incorporated into learning but we need to make sure students are allowed to discover what works best for them.

In the Twitter thread the article mentions, LeCun makes his claim only for "high-resolution" images and the article assumes 1024x1024 to fall under this category. To me, 1024x1024 is not "high-resolution." This assumption is flawed imo

I currently use convnext for image classification at a size of 4096x2048 (definitely counts as "high-resolution"). For my use case, it would never be practical to use VITs for this. I can't downscale the resolution because extremely fine details need to be preserved.

I don't think LeCun's comment was a "knee-jerk reaction" as the article claims.
