IIRC the Bolivians did use some armor (some Vickers 6 tons and some tankettes) in the Chaco War, so presumably these hypothetical armored cars could be used against Paraguay as well.

Specifically, that's the CL-1200, which was a design for an improved Starfighter to compete in the export market in the 60s (against the F-5 and similar planes). It would've also had a larger wing and a bunch of other modifications.

Turns out Gatwick airport might have been accidentally shut down by police drones.

Welcome to SH!
Just thinking about it off the top of my head, it could possibly be done (Brazil heavily upgraded their M3 Stuarts, and the NM116 was a heavily upgraded Chaffee that served into the late Cold War), several countries (such as Israel and Chile) kept them going until the 1980s. Is the hypothetical country for some reason unable to obtain more modern armor such as T-55s, T-72s, or M60s? Those tanks aren't too expensive, and there's numerous upgrade packages available for them already developed (even for something as old as the T-55).
For reference, some turret ring diameters;
- M4 Sherman: 69 inches / 1752 mm
- T-54/55: 71.8 in / 1825 mm
- BMP-2: 68.5 in / 1740 mm (taken from a translated Russian site, use with caution)
- M48 & M60: 85 in / 2160 mm

That looks pretty neato. How are they planning on dealing with retreating blade stall? (assuming "twice the speed" isn't just marketing fluff)

Had a solid day at Gore today, bit annoyed that some of the stuff they said was going to open didn't. Snow was pretty good quality though, and they're working pretty hard at making more (did run into the problem of skiing on a trail with ongoing snowmaking and having my goggles ice up pretty bad).
Did run into the problem of having people in the group with different stamina/skill levels. Our group of 7 people ended up split into 2 or 3 groups the whole day.

Planet Nine is supposed to be roughly Neptune sized, even with the most bullish projections for Oort Cloud mass/density it will have cleared its orbit.

And if I trust this document, apparently you guys also have legal limitations with load following on top of the technical aspects:
In some countries, there are explicit regulatory limitations on manoeuvring in the automatic mode.
For example, according to the US Code of Federal Regulations (10 CFR Part 50),
“the licensee may not permit the manipulation of the controls of any facility by anyone who is not a licensed operator...”
and
“Apparatus and mechanisms other than controls, the operation of which may affect the reactivity or power level of a reactor shall be manipulated only with the knowledge and consent of an operator or senior operator licensed pursuant to part 55 of this chapter present at the controls”.
Although this does not prohibit power load variations controlled by the operator (if justified from the technical and economic viewpoints), maneuvering in automatic mode is not authorized by current regulations in the United States.
This seems like something that should be revisited now since automatic systems are significantly more advanced than when the regulation was presumably first written (a cursory search doesn't reveal when that section of 10 CFR 50 was enacted). Appropriately tested software monitored by an operator should be sufficient for civilian applications.

Very detailed report from MIT on the use of nuclear in low carbon energy infrastructure; http://energy.mit.edu/research/future-nuclear-energy-carbon-constrained-world/
TL;DR Nuclear becomes more attractive the more you reduce your emissions goals (in terms of kgCO2/kW)

Good looking boats, and it seems that they're also using modular construction like the Virginias (I assume the Russians and Chinese build modular also, but I don't know offhand).
Are they still fucking around with low-enriched reactors for some dumb reason?

And naturally no movie theaters near me are showing it.

So a completely frivolous example, but I was quite pleased to run the numbers on optically-pumped lasers and realise that your average solar-thermal tower setup could conceivably be converted into a megawatt-class laser.

Canada might be walking back the Type 26 purchase; https://nationalpost.com/news/canada/feds-ordered-to-postpone-award-of-60b-warship-contract-because-of-allegations-the-ship-they-want-to-buy-cant-meet-the-navys-requirements
A federal trade tribunal has ordered the government to put a $60-billion program to buy a new fleet of warships on hold while it investigates claims the vessel selected doesn’t meet the military’s needs.
Last month, the federal government and Irving Shipbuilding selected Lockheed Martin Canada as the preferred bidder for the Canadian Surface Combatant program. Lockheed Martin had teamed with British firm BAE to propose providing Canada with 15 of BAE’s Type 26 frigates.
But Alion, a U.S. firm that also submitted a bid on the project, contends the Type 26 can’t meet the Canadian navy’s stated requirements and filed a complaint with the Canadian International Trade Tribunal (CITT).
Several European shipbuilders decided against submitting bids for the $60-billion project because of concerns about the fairness of the process. -

ERJ-190 flight controls don't work, plane flails around uncontrollably for a while.
Immediately after take-off, with adverse meteorological conditions, the crew felt that the aircraft was not responding adequately to the commands, developing oscillatory wing movements.
The crew, using all the aircraft control resources for its 3 axis, immediately tried to counter the movements, however without understanding the cause for the flight instability and without being able to engage the autopilot.
Realising that they were without effective control of the aircraft, only being able – with considerable effort – to minimize the oscillatory movements, with high structural loads involved during some recovery manoeuvres and using crossed commands.
The crew immediately declared emergency while trying to diagnose the cause for the abnormal roll of the aircraft, continuing to struggle to gain its control, having no malfunction indication from the aircraft systems, just the continuous alerts for abnormal flight attitudes.
The flight requested to return to Alverca. About 13:37 UTC the flight requested to climb to FL100, again stating they had "flight control problems".
The situation did not improve, and the performed trajectories caused the aircraft and the persons on board to sustain intense G-forces, and causing the aircraft complete loss of control for some moments at multiple instances.
Considering the situation criticality, the crew requested several times for headings in order to be able to reach the sea for ditching, not being able, however, to keep the intended headings. \They did manage to land safely, and it looks like they did a decent job resolving the problem.

I could see that being an interesting idea to add flavor, but not doritos flavor or onion ring flavoring.

I have a copy of that book, let me know if there's anything in particular you're interested in.
