Why was @LudwigAhgren's Twitch stream yesterday a masterpiece in creating live content?

Java was first released in mid-1995, just 6 months before JS.

By 98, when I went to college, Java was already used for all the first level courses in the CS program.

How did it catch on so quickly (just 3 years) to shift university curriculum, which is usually so slow/behind?

I wonder why Java was so respected and JS was not? Why/how was Java already seen as such a stable and mature language?

Not just Java, other languages (like python) were also released around/near 95, and also seemed to get to "mature" respect status. much quicker.

I bring all this up because my impression of Java in 98 was that it had been around "forever" (as had C++ first developed in 79, but not standardized until 98!), but that's not. true at all. These were all new languages around the same time.

I'm sure the language designs had different merits, and the target applications meant a different perception and reception, but...

it sure seems like the industry (and academics) just decided Java and C++ were the stable mature ones and langs like JS were toys.

BTW, before you assume JS was nascent/immature b/c the web wasn't much of a thing yet, remember that JS was actually released as LiveScript on the server before it was released in a browser. So "server-side JS" was always part of the story, not just Node 15 years later in 2009.

So, I want to talk about how sexual harassment and fair pay are linked at Google (and beyond), because I think that's an angle that isn't being highlighted enough in the coverage of these walk-outs. I'm going to frame it largely around my personal experience there. Thread.

When I was sexually harassed by the director of the area I was working in, I was afraid to report it because I was worried that "getting him in trouble" would result in the subtle retaliation of missed leadership opportunities.

I wanted to continue working on the team I was on, because I'd gained a lot of very deep knowledge and expertise in that area, as well as reputation and camaraderie with the other folks working in that area. I didn't want to make the situation more "difficult."

To get promoted at Google, several need to happen: 1. you need opportunities for ownership and leadership above your current level (basically, opportunities to show you're working at the next level you're trying to get promoted to). The work you're "assigned" has a big impact.

2. You need glowing reviews from peers, *at or particularly above the level you're hoping to get promoted to.* Basically, you need people a lot more senior than you to say you're doing awesome work.

Here’s a SPAC thread covering some basics for new followers. I will pin this to my profile if you want to share to anyone interested in SPACs.

SPAC timelines consist of these stages:
IPO – SPAC raises cash and begins trading as a unit. The cash is placed in Trust.
Searching phase – After IPO, the SPAC management team looks for a company to merge with. This is typically 24 months but can be shorter depending on the SPAC

LOI/Rumor – A letter of intent is announced publicly or Bloomberg/Reuters etc. breaks news of a rumor that a SPAC is close to a deal with a target.

The LOI/rumor stage does not always happen, most go straight to a definitive agreement. Rumors should only be considered to have value if from a trusted news source, internet rumblings are pure speculation. During this stage, a deal can still fall apart and not be signed.

Definitive agreement (DA) – deal officially inked. The SPAC begins filing paperwork with the SEC to have the merger approved to take the target company public. This process typically takes 4+ months after the DA is announced.

The New York Times article about SlateStarCodex is finally out and it is...bad. There's a lot I could parse, but let me just walk you through one paragraph that is so misleading as to be

Take the first sentence of this paragraph. Now, technically the clause--"who proposed a link between race and IQ"--could simply modify "Murray" and have nothing to do w/ SSC.

But 99% of readers are going to assume that the clause actually defines SSC's alignment with Murray. In other words, the author is strongly implying that SSC shares Murray's racist beliefs.

And that would be big(!)...if it were at all true. It is not. Indeed, if you go to the hyperlink, you'll find that SSC's purported "alignment" has nothing to do with Murray's "Bell Curve."

What SSC & Murray agree about is that poverty is partly hereditable and thus very sticky, so much so that the proposition job retraining programs will meaningfully address mass economic disruption is a pie-in-the-sky fantasy.

For decades, Jeff Bezos shunned ads.

But now, Amazon’s ad business is huge: it’s on a $30B+ annual run rate (more than 2x the combined sales of Twitter, Snap and Pinterest).

Here’s how it happened 🧵

1/ Amazon doesn’t break out its ad business separately in financial filings. However, most analyst believe ads make up the majority of its “Other” revenue segment.

This figure has exploded from $1B in 2015 to a current annual run rate of ~$32B.

2/ In 2009, Bezos said “ads are the price you pay for a crappy product”.

But the business is so lucrative that Amazon’s interface has been swamped with ads:

◻️ First 3-7 search results (left in red)
◻️ Most of the product page (right in blue)

3/ Prior to the rise of ads, Amazon set out to build the ultimate organic customer recommendations engine.

The approach was codified in a famed 2003 research paper: “Amazon Recommendations: Item-to-Item Collaborative Filtering.”

4/ In recent years, Amazon organic recommendations:

◻️"Customers who bought this also bought this"
◻️"Customers who viewed also viewed"

Have been replaced w/ ads:

◻️ "Sponsored products related to"
◻️ "Brands related to this category"
