This is a complete misunderstanding of warfare. Drones cannot take and hold ground. Without infantry, an external power cannot exert influence over an area. Sure, they can wantonly kill civilians, but that doesn't mean they are in char

Dropping an RKG-3 grenade on a tank from a cheap drone also requires that the tank be stopped -- something that happens far less often in a war of movement than in trench warfare. The war in Ukraine has been extraordinarily static (like the

I definitely find that when I'm close to burning out, I'm eager to start arguments and throw unnecessary barbs into conversations. It's a more specific example of the general symptom of beginning not to care.

Such a fascinating read! I particularly enjoyed the part where they are testing the radar cross section of Have Blue, the initial design for the F-117. They had put it up on the test stand, but think the radar is malfunctioning, as they don

During the Cold War, both the United States and the Soviet Union had nuclear artillery shells for 155mm and 152mm howitzers, respectively -- those would have a yield of about 100 tons on the low end, up to 2 kilotons on the high end. Higher

They still have the ability to put nuclear warheads anywhere on the globe, by virtue of their ballistic missile submarines and the nuclear warheads those ballistic missiles carry. The Trident D5 missiles have a range of more than 7,500 mile

For sure, but then you take it out before you serve it (at least in my experience).

The F-19 was what people speculated the rumored "stealth fighter" would be named. There had been rumors for years, but the public didn't see it for the first time until 1988. In Tom Clancy's book Red Storm Rising, about

An alternative approach is to use something like Thrift to type your responses —- properly implemented, an RPC framework like that is amazing. So much validation boilerplate removed on the backend, and receiving it on the frontend as a nice

That, or just a string in your application’s code. The problem with using the ORM as you describe is that when you hit any sort of scale, you need to be doing bulk operations, otherwise your latency goes through the roof, to the point that

There also weren’t reconnaissance satellites in 1941 that would detect some fleet leaving Vladivostok (or some western Chinese port). There weren’t over the horizon radars, or airborne interceptors with radar that can see hundreds of miles.

`join` isn't so bad -- you are connecting two tables based on a common value. If you have `person` and `address`: create table person ( id serial primary key, first_name text not null, last_name text not n

Steamboat Springs is an amazing place! One bit of feedback on your website -- it's agonizingly slow to have to wait for the list of cities to scroll -- a bar or an arrow would be lovely.

An excellent book! Have you read Ian Toll's books about the Pacific War? Similarly well-written and super in depth.

Yes, but CWIS isn't the only anti-air defense on a US Navy ship -- there's also the RIM-116 Rolling Airframe Missile, as well as vertically-launched anti-air missiles (RIM-162 Evolved Sea Sparrow Missile). CWIS is the weapon of la

Yes, U.S. Navy nuclear submarines go under the polar ice caps somewhat frequently -- as did Soviet (and do Russian) nuclear submarines as well. It's a good place to hide from prying eyes, as not only can ships not (easily) follow you t

Do you think there will actually be a redesigned 13" MacBook Pro? My assumption was that it was being replaced with the 14", but maybe I'm mistaken!

Airburst rounds with timers set by calculation, not airburst rounds that can blow up when they reach a specific point determined by proximity, distance, GPS, etc. It's a completely different kind of airburst.

Well, and in the same vein, that Congress has essentially become a zero-sum game, where one party attempts to cut taxes, slash regulation, and prevent the government from paying for anything except for a larger military. The idea that the g

US companies do have to pay taxes on overseas profits, which is why they so often have subsidiaries based overseas. Those entities do not have to pay those taxes.

Germany, the aggressor, had a substantial chunk of France and Belgium in their control at that time, and were, for all intents and purposes, winning the war from defensive positions. They had no incentive to initiate peace talks. Had the Fr
