jeffdn··on James Webb Space Telescope reveals that most galaxies rotate clockwise
If all of the galaxies we see rotate the same way, are we “looking down” from a pole and seeing only those with the same rotation we have, as opposed to a more equatorial view that would be evenly split.

I'd make sure to do an extended trial run first. Painful transition.
jeffdn··on Institutions try to preserve the problem to which they are the solution
I’d start by saying that the Russians aren’t winning the war, it is in a period of stalemate, like 1915 or 1916. Accepting tens of thousands of casualties for incremental movement of a front line, over time periods that allow the side withdrawing to first build new fortifications to fall back on, is not a recipe for success. The Russians are digging deep into Soviet-era stockpiles, rolling out tanks built in the ‘50s and ‘60s (T-55 and T-62, respectively). Each of these is much less well equipped to face Western-style military hardware than more modern variants. Russia’s ability to replenish its stockpiles is at even more a disadvantage than the West, and meanwhile Ukraine has been tooling up to build shells of their own.

The U.S. has (had?) colossal stockpiles of shells and ammunition. There is a false equivalence between the ability to supply the Ukrainians at a rate of 10,000+ shells a day for years on end and the ability of the United States to engage in a major conflict. The Russians are also having trouble keeping their artillery pieces adequately supplied. The calculus is about the acceptable rate of drawdown of stockpiles in relation to the increase in the likelihood of a near-peer conflict arising due to the support given by the very drawdown of those stockpiles. If we give everything we have to Ukraine, and they lose, for whatever reason, then we have disadvantaged ourselves.

However, any major conflict between the United States and a near-peer adversary wouldn’t be so heavily reliant on artillery as this current war is — the U.S. has spent decades building an Air Force that can dominate the battle space in ways that artillery alone cannot match. As Ukraine is set to receive several squadrons worth of F-16s this year, I believe we will see things change. Planes can interdict resupply and troop movements in ways that are beyond the capability of artillery. SEAD aircraft can target and destroy SAM radars to allow large strike packages to accurately blow bridges and rail lines with a much greater radius and accuracy than any other conventional munition.

It is very cynical realpolitik, but Russia’s armed forces have been gutted with this approach.

Is it a surprise to you that all of the countries that have historically been imperial subjects of Russia seek protection from the possibility of that eventuality coming to pass again? Is it surprising after Georgia in 2008 and Crimea/Donbas in 2014 that Ukraine would want some assurance of security and independence for the remainder of their country?

The United States is certainly not solely responsible for the demolition of all of the factories of Europe. Sure, they played a majority role in the bombing of Germany, Czechoslovakia, occupied France, and Italy, but that is not the full picture and you know it. The British bombed, the Germans bombed, the Soviets bombed, and massive ground campaigns carried on by all of the above with the profligate use of artillery didn’t help either.

jeffdn··on 'AI' Is Supercharging Our Broken Healthcare System's Worst Tendencies
A major contributing factor to the lack of realized benefits with electronic health records in the United States is that the interoperability specification, CCDA, is only loosely complied with under the "meaningful use" rule from Health and Human Services. Certification is done on site at the EHR manufacturer, in an environment controlled by the manufacturer. The demonstration of compliance does not have to be done in a default "out of the box" environment, but merely that the system is _capable_ of being configured in a way that allows for emitting standards-compliant CCDA.

In practice, this means that most manufacturers do not build systems that are standards compliant by default, and definitely do not install systems that are standards compliant in their initial configuration. Then, individual healthcare practices add customization on top of that, which further complicates data integration.

You can frequently get same-day delivery for a nominal fee, even within a few hours! My partner’s phone broke after she dropped it one too many times at about 7:30am on a recent morning, and we had a new one in hand without leaving the house by 10:30am.
jeffdn··on A detailed comparison of REST and gRPC
An even worse mistake is treating all three of those model layers as one and the same, which tools like Django REST Framework make it so easy to do. It all seems well and good for a while, as developers build up a big codebase with ease, but then are confronted with an almost insurmountable amount of work when the need to refactor arises.

The thing I’ve noticed when stepping into a codebase where this problem has been allowed to occur is the lack of layers of abstraction. Having those different models built up from the start allows for an application to shift along with the needs of the product. Having a single layer, with the endpoints talking literally directly to the ORM models, almost inevitably leads to calcification, spaghettification, and disastrous performance.

In 1985, there were about 170,000 coal miners in the United States — the peak of over 800,000 was in the 1920s. There simply isn’t a comparison in the scale there.

Both F-22 and F-35 have internal bays for weapons. Sure, they can also carry external loads that blow up their small RCS, but in a hypothetical scenario where that low RCS is still valuable (i.e. contested airspace), they wouldn’t be carrying external stores that make them vulnerable.

This seems like the kind of thing you could take to your skip-level or even higher in the management chain. A single new manager causing multiple long-serving employees to become disgruntled should be a bright red flag to a competent leadership team.

jeffdn··on The Collapse of U.S. Healthcare – The Perspective of a Primary Care Physician
This is essentially what the “public option” in the original Obamacare proposal was — an opt-in publicly owned insurance company, which would compete with all the other insurers, but not have the overhead of their business models. Unfortunately, it was axed alone with much of the other important aspects of that bill.

The great irony is that the initial Obamacare proposal was a Republican policy — originally proposed in the mid-‘90s as an alternative to the proposal from the Clinton White House, and implemented in Massachusetts by Mitt Romney when he was the governor. The Republican congress and conservative media machine were so invested in seeing Obama fail that they instead branded it socialism and fought it tooth and nail. It would’ve been a fantastic opportunity for a resurgence in bipartisanship in government, and could potentially have averted the subsequent 14 years of animosity and bitter obstructionism. Ah well, so it goes.

jeffdn··on Yes, a branch of the Army Corps of Engineers did make a cat calendar
It doesn't strike me as a design flaw that a carefully calibrated item like a panoramic telescope used for accurately firing artillery at ranges up to 20 kilometers would need to be protected before the howitzer is towed along a muddy, bumpy road.
