<p>So much of the content is extremely stale, and it even matters for languages that you would think are relatively unchanging.<p>It seems like they must have put almost no incentives in place for the instructors. Setting up a course must take even more effort than running a full semester course in their own school, but since no one is making new versions Coursera must not be paying them like it, or offering equity in the platform. I imagine that teaching students in person is also a lot more rewarding,<p>I haven’t taken any recent online courses, but EdX looked like it might still be good.</p>

<p>Didn’t the gamification course have one of the relatively few well done peer assessments? The course was good, but it’s interesting now that gamification features completely turn me off now on any platform or program attempting to motivate me toward a specific end, regardless of whether that goal is in my interest or the interest of someone else trying to make money.</p>

<p>The model thinking course was interesting but it should have had a follow up that was much more than a freshman survey course treatment of each model.<p>Reading online it seems like most people got the impression that it was establishing that all models are essentially useless. Instead it was showing that each of these models were an extremely efficient way to understand some dynamic situations, but that it’s still absurd to focus on only one model when trying to understand the world.</p>

<p>My dad had a class in medical school where the professor dipped his finger in a beaker, talked about mechanisms for sugar in diabetic patients’ urine, and then proceeded to stick his finger in his mouth. He had all of the students do the same, who noted that the sugar was apparent.<p>He concluded the class by talking about the importance of observing patients, and pointed out that he had tasted a different finger than the one he had put in the beaker.</p>

<p>I don’t really understand this response.

<p>At least around 370 BC, in Plato's <i>Phaedrus</i>, Socrates expresses a strong opinion against writing of any kind through a conversation between the Egyptian gods Theuth and Thamus discussing the invention of writing.<p>Thamus:<p>> "For this invention will produce forgetfulness in the minds of those who learn to use it, because they will not practice their memory. Their trust in writing, produced by external characters which are no part of themselves, will discourage the use of their own memory within them. You have invented an elixir not of memory, but of reminding; and you offer your pupils the appearance of wisdom, not true wisdom, for they will read many things without instruction and will therefore seem to know many things, when they are for the most part ignorant and hard to get along with, since they are not wise, but only appear wise."<p><a href="https://www.historyofinformation.com/detail.php?entryid=3894" rel="nofollow">https://www.historyofinformation.com/detail.php?entryid=3894</a><p><a href="https://plato.stanford.edu/entries/plato-rhetoric/#Pha" rel="nofollow">https://plato.stanford.edu/entries/plato-rhetoric/#Pha</a></p>

<p>I am pretty skeptical about the value of learning to build websites. I think it is too tempting for students to devote significant time to something that is not foundational knowledge and where they won't get any valuable feedback anyway.<p>It makes me think back to my writing assignments in grades 6-12. I spent considerable time making sure the word processor had the exact perfect font, spacing, and formatting with cool headers, footers, and the footnotes, etc. Yet, I wouldn't even bother to proofread the final text before handing it in. What a terrible waste of a captive audience that could have helped me refine my arguments and writing style, rather than waste their time on things like careless grammatical errors.<p>Anyway, I do agree with the idea of incorporating Excel, and even RStudio for math and science as tools, especially if they displace Ed-tech software that adds unnecessary abstractions, or attempts to replace interaction with knowledgeable teachers. One other exception might be Anki or similar, since they might move rote memorization out of the classroom, so that more time can be spent on critical thinking.</p>

<p>I think it’s a great reaction to news stories to imagine how you could have made the same bad decisions. Furthermore this public confession of being able to imagine making bad decisions might encourage a similarly minded to 20-something to wonder why an older version of themself is so afraid of even having such a dataset. It might even prompt someone to destroy some long forgotten cache of data they exfiltrated a long time ago.<p>I don’t think there’s a risk that it will influence a rare person in power to enforce the rules to go lighter. I just think it encourages people to be less reckless with hoarding data who might otherwise put themselves in danger.</p>

<p>They are like Vim. “Alt,letter,letter,arrow,letter,letter,arrow,enter”, etc. Rather than a single combination of keys, it is a series of key presses.<p>I agree that it might be trivial to set up for spreadsheets, and it would be really useful for other spreadsheets, and many other applications. I suppose a hurdle is how context sensitive the commands are depending on the cell or range of cells activated, and their contents and data type.</p>

<p>I use macOS most of the time, but switch to a Windows VM for Excel. Without the same keyboard shortcuts, the macOS version ends up having a fraction of the power available to experienced users of the Windows version. For people who use Excel extensively, LibreOffice or Google Sheets would have to offer some remarkable new killer features to make it worth the switch. I don’t think feature parity alone would make the benefits of Linux outweigh the significant transition costs.</p>

<p>It is a mixture of experts model so it will run on a computer with a lot of RAM and a GPU.<p>Alternately, on an M3 Ultra Mac Studio with 256GB of unified memory, you can run a 4bit quant of GLM-4.6 at about 20 tokens/second. That compares to about 40 t/s for a 6bit quant of MiniMax M2. I am not sure how fast these will run if you have a Mac Studio 512GB that can load the unquantized versions of the models.</p>
