React was a massive improvement over Ember.js, Backbone.js and their ilk, which at the time as a young dev I couldn’t grasp by myself.

React, however just clicked. f(state) = UI just makes sense


Which is not at all how it works in practice. In a large React codebase you have state scattered throughout contexts, GraphQL caches and complex hook dependency trees.

Throw in SSR and component memoization and you really have no idea what caused a UI change to occur.


the problem with useEffect is how much it gets used when it doesn’t have to be

its overuse makes it evident that hooks (or React in general) is poorly understood


Starlink’s direct to cell service works with regular 4G LTE radios


this is really annoying to read.

go open the careers page for most mid-tier tech co’s (Coinbase, Rippling, Affirm) and count the number of SWE jobs in India/Latam/Eastern Europe vs the U.S.

Say you get your wish of no immigration. How are you going to force these companies to not hire abroad instead?

At least if the worker who competes with you is in the U.S., they have the same cost structure as you and won’t undercut you as much or at all on wage.


I’d much rather compete with an immigrant who is in the U.S. and has the same cost structure as me than we someone based in India/LATAM and will undercut me on wage 3x.


I'm seeking employment right now. How do I make sure the government knows that?

Is there a number I can call to make sure I'm included in the statistics?


You don't call them. They call you (but very few people really - so most likely not you).


Why did the CEO extract money from specifically Google and why did Google continue funding them despite all the shortcomings?


The CEO, Anne Wojcicki, was married to Sergey Brin (founder of google): https://www.nytimes.com/2007/05/23/technology/23google.html Her sister Susan was also an exec at Google and provided space for the company when it first got started. Sergey loaned a bunch of money to 23&me before that, and his loan was repaid when google invested (which sounds like a conflict of interest to me, but then again, Sergey is a bunch of conflict of interests). Later, GV (Google Ventures) invested more in 23&Me. At the time, the head of GV was Bill Maris, who had worked with Anne before she founded her company (and I was an advisor for GV around that time; if they'd asked me, I would have said "don't put more money in this turkey").

So basically a little family of people who wanted to see the company succeed. I think they've been given their time to succeed and at best, have reached a sort of steady state where they are not going out of business, but also aren't achieving the interesting mission they were based on.


Note: the bandwidth is around 7Mbs per "beam" and the "beams" are 40-100km in radius, so very large. This isn't a replacement for traditional cell service, but specifically designed for emergency service in remote areas. This service will work with all phone equipped with LTE (4G).

2 other strategies currently being attempted: Pepper a bunch of pizza-box sized satellites out there (similar strategy as popping them on SpaceX satellites) and go for a giant mesh: https://lynk.world/how-lynk-proved-direct-two-way-satellite-...

Put gigantic satellites that unfold using the tech from snap-bracelets and compensate for distance with a gigantic antenna: https://ast-science.com/spacemobile-network/bluewalker-3/

With how many cell-phone providers and towers out there, I have no doubts they'll all be up to their eyeballs in work on this. Also, SpaceX just lost funding and might be trying to pick up some of the rural broadband funds Lynk and ASTS are going for: https://www.pcmag.com/news/spacex-loses-appeal-to-receive-88...


I learn so much here every year! Next year, I want to contribute more.


It’s a sad state of affairs that in order to own a house and raise children, one pretty much has to become an entrepreneur.

There are high paying jobs out there, but they’re rare and there’re only enough of them for a tiny proportion of folks.
