I had an argument with [@josephhill](https://hachyderm.io/@josephhill ) over this screenshot. I said “let’s remove it, I can’t tell the difference”. He said “I picked this one because the difference is so clear”

Some 20 years ago, I said in some blog post “Israel is a terrorist state” and I was hounded for years by Zionists that would make sure all my bosses knew about it.
It just took 20 or so years for this to be generally acknowledged, and soon, hopefully people won’t pay a financial price for speaking up about this apartheid regime.

The hubris of Trumpism really infects everything it touches.
And yet, Iran is committed to extract the guarantees from these losers that it demanded since the start.

What happened at Block will likely happen everywhere else - companies now find themselves with an overstock of talent, and they are not structurally ready to absorb additional capacity.
People will achieve more with less - but this also opens the doors to building entire new businesses.

That said, the new approach consumes twice as much memory at startup, so it defeats the purpose of this exercise.

A friend came to visit me yesterday, and he was sneezing. And I said “is that covid?” And he goes “I don’t think so, it’s just a cold”.
Tested him on the spot.
He had covid.

holy shit. I just skimmed it, this is so bad. I was aware through the years of minor anecdotes, nothing like this.
(I hosted stallman at my place some 30 or so years ago, and for years I bonded with other hosts comparing notes. Short version: you don’t want to host him)

Israel is planning to conquer and annex parts of Gaza. To do so, they will need to exterminate the Palestinians there.
Despite watching a year worth of their extermination campaign, they still manage to impress with new and innovative approaches. We are out of words for this carnage.

The escalation of violence in Lebanon and Palestine are the direct result of the policy of the United States: with unlimited military funding and diplomatic support for Israel, there is no room for finding peaceful solutions, only more death and mystery.
What an abject failure and a betrayal of principles.

I think as developers, we have a duty to not only write code in safe languages, but also round every rectangle we come across.

Embedding Godot's EditorInspectorPlugins into SwiftUI, so I can bring all existing 30 from Godot, and allow for third party plugins to render - without having to rewrite each one:

I think the issue will be American companies with Israeli employees working on proprietary products.
They lack the various defenses open source has.

I don't think Israel realizes how this supply-chain attack means that every Israeli software developer and hardware developer will now be treated as a potential attacker on the company payroll.
Every commit should be treated as being developed by Mossad.
And to think it was only a few months ago that we learned about the helpful contributor that injected trojans on open source libraries.
