At 0:47 the video clearly shows three fingers on the "top" part of the egg. At 0:58 the ping pong ball exercise clearly shows three fingers on the top part. The break at 1:08 also has three fingers on the top. But then for some reason at 1:12 the performer switches to two fingers above the break. The double break at 1:33 also shows two fingers above the crack.
Some of the egg breaks in the video pull the halves away from each other and other breaks use a slide or shearing/transpose movement to create gaps between the halves.
There is nothing in the video about how close to hold the egg to the palm of your hand. With the dozen or so eggs I tried the key was (counter-intuitively) to hold the egg close to your palm so that the pads on your palm act as a fulcrum as you try to pull the halves apart. If you just hold the egg with the tips of your fingers its difficult to create the necessary space. But maybe that's just me and my lack of dexterity.
I guess instead of complaining I should create my own video.

While somewhat off-topic, I had an interesting experience highlighting the utility of GitHub's Copilot the other day. I decided to run Copilot on a piece of code functioning correctly to see if it would identify any non-existent issues. Surprisingly, it managed to pinpoint an actual bug. Following this discovery, I asked Copilot to generate a unit test to better understand the identified issue. Upon running the test, the program crashed just as Copilot had predicted. I then refactored the problematic lines as per Copilot's suggestions. This was my first time witnessing the effectiveness of Copilot in such a scenario, which provided small yet significant proof to me that Language Models can be invaluable tools for coding, capable of identifying and helping to resolve real bugs. Although they may have limitations, I believe any imperfections are merely temporary hurdles toward more robust coding assistants.
How did you prompt Copilot to identify issues? In my experience the best I can do is to put in code comments of what what I want a snippet to do and copilot tries to write it. I haven't had good luck asking copilot to rewrite existing code. Nearest I've gotten is:
// method2 is identical to method1 except it fixes the bugs
public void method2(){

Based on some light reading just now:
- SWP is a means of treating green coffee beans pre-roast. They can be roasted any which way afterwards.
- Any type of bean can be treated this way.
- The process is pretty specific in targeting just caffeine. In removing caffeine though, the total dissolved solubles in the end coffee will be lower for the same amount of beans. Probably a lessor body unless you use more.
Interested to hear from someone who has tried it.
I roast my own coffee beans. I usually get decaf SWP beans from Sweet Marias. https://www.sweetmarias.com/green-coffee/decaf.html
The decaf SWP beans start out a different color of green bordering on tan compared to the light green of regular "green" coffee beans. Its not just the starting color, they roast differently too. Coffee beans crack during roasting - there is a first crack and then if you want it dark there is a second crack. The sound is usually pronounced. With the SWP beans the crack sound is more of a poof. Apparently SWP changes the structure of the beans, possibly introducing cracks or holes. The roasted beans seem drier and duller brown in color, less mahogany, less shiny. Its hard to know what the flavor impact of SWP was b/c I haven't tried the same beans before they were made decaf. It could just be my own prejudice or lack of skill in roasting but I would say on average the decaf coffee turns out 5-10% worse in quality.

In many-to-most cases 4G and especially 5G will simply outperform Starlink. If you have the 4G it may not even be necessary to bother with the Starlink. Unless you want redundancy of a 2nd connection or you can only get a really terrible data plan running both is not likely to make much sense. Starlink also has very onerous North-South field of view requirements that are actually often hard to meet even on completely remote sites (speaking as a Starlink customer with a handful of trees in the yard). Cellular is nowhere near as fussy about placement.
Starlink makes most sense when you have no 4G or 5G reception at all, generally speaking.
Not sure I agree about the 4G/5G comment. I got an unlimited 4g/5g hotspot through Calyx Institute that uses the TMobile network ( https://calyxinstitute.org/membership/internet ). I now also have Starlink. The Starlink service is faster and lower latency. I have noticed Starlink getting slower over the past couple months but it is still quite fast. In my experience the downside to Starlink is that several times a week it drops out completely for 10-20 seconds. I thought I was going to have issues with the trees near the location of my antenna but the app shows almost 0 obstruction in the FOV Starlink cares about. It was surprising to me how far north the antenna wants to point. I was picturing it pointing south like a dish would for a geo satellite but Starlink aren't geo.
I've also been a customer of two different local wireless point-to-point ISP. One worked great when it wasn't foggy and when the trees didn't have leaves - so only about 1/4 of the year. The other had 800ms pings and also went down frequently. Starlink has been game changing.

Are there any OMSCS students lurking that can share their opinions? (I'm a prospective and would love to hear it).
I completed the program in 2018. I'm glad I did. It was a tremendous amount of work and I was already working full time with a lengthy commute and family commitments. Pretty much every minute of my weekends and 10pm-12pm most week nights. I had to do maybe 3 all-nighters when schedules didn't line up. Some of the classes are much harder than others and should be taken by themselves. Other classes are less demanding and you can 2x or 3x. The video lectures tend to be very well made. Some of the classes make extensive use of Piazza - which I grew to loath. The assignments can be challenging but also sort of fun. Each class is different though. You're welcome to email me at gmail or yahoo if you have specific questions.

The article's argument against programs like OMSCS is that the only feedback is from teaching assistants. This claim is not true. There is (a) automated grading of programming assignments, so your program runs against unseen test cases, (b) informal feedback from TAs and other students on Slack and other unofficial channels, (c) formal feedback from other students as part of grades in certain classes and group projects, and (d) feedback from professors to student questions during video office hours (in some courses).
Yes, lots of assignment and exam feedback does come from TAs, but it is comprehensive and valuable. The TAs are well versed in the course material and relay information and questions from and to the professors. I completed the program and at no point did I feel like I was receiving too little feedback on my work.
I also completed the program. Some classes did better at feedback than others. But honestly, whats so bad about getting feedback from teaching assistants? The TA for Reinforcement Learning wrote the book Grokking Deep Reinforcement Learning and has experience using RL in industry. If that is the worst they can say about OMSCS its sort of a pretty big endorsement.

Is there a way for developers, who do not have AI/ML background, to get started using this ? I have been curious about GPT-3 but I do not have any AI/ML experience or knowledge. Is there a "approachable" course on Coursera or Udemy that could help me get started with technologies like GPT ?
I would not start with this model. Its impractically large.

What are the others? Any recommendations?
I took these courses from Georgia Tech via OMSCS but they are also on udacity.

https://omscs.gatech.edu/cs-7642-reinforcement-learning (I took this before ML but its supposed to come after. There is some overlap. Probably my favorite graduate course.)
https://omscs.gatech.edu/cs-7646-machine-learning-trading (IMO not amazing)
Much more basic (took this before OMSCS):

I'm sure there are many more.
