At what point can we just return to 1990s wheel sizes, add the motor to the wheel, and have the same unsprung mass as we have with today's gigantic wheels?
grandinj · 2 months ago
motors do not like the impact loads that wheels see, which is why bicycles with hub motors do not have a long lifespan

Or.... smoking may be indicative of people from poorer backgrounds, where health is generally lower. (cant say for sure, but thats the case where I am from)

While the Linux Foundation can provide some support, it's still up to each project to find their own maintainers (and pay for them).

Is this not what the Linux Foundation was about at one stage?

Taking ownership of unmaintained projects so that at least they have the bare minimum of patches being applied, CI/CD running, releases being created?

There's some weird ones you'd never think of that originate an inordinate amount of bad traffic. Like Seychelles. A tiny little island nation in the middle of the ocean inhabited by... bots apparently? Cyprus is another one.

Re: China, their cloud services seem to stretch to Singapore and beyond. I had to blacklist all of Alibaba Cloud and Tencent and the ASNs stretched well beyond PRC borders.

There is a Chinese player that has taken effective control of various internet-related entities in the Seychelles. Various ongoing court-cases currently.

So the seychelles traffic is likely really disguised chinese traffic.

I have a feeling that they still need to guarantee availability of spares if they fix it themselves, do they not? They still have to create documentation for their engineers, do they not?
grandinj · 6 months ago
If you repair it yourself, you have more flexibility in terms of replacing spares with newer items i.e. replacing a whole module when it a part of that module becomes hard to come by.

Internal documentation ..... hmmmm.... LOL.... Often not, word of mouth is the rule.

If there is internal documentation, it's generally pretty rough. Getting it to the point where you can hand it to external parties is a lot of work.

Fair point - but I see no reason why you'd commision unsupportable ovens or lifts - these are not unique things to aircraft carriers.

I'd suspect custom ovens or lifts are more likely to breakdown than some standard industrial ones whose manufacture and design has been optimised over many years.

Just like new software is much more likely to have bugs that battle tested ( sic ) software.

Sadly the US military (like a lot of militaries) are in love with custom requirements. And there is very little leeway for negotiating them out. So unnecessarily custom solutions are the norm.

The idea that if your ovens break or even worse the lifts that carry the nukes - and you can't repair yourself, but rather have to fly a contractor out is clearly absurd.

Who signed such a contract?

grandinj · 6 months ago
It was muuuch cheaper that way.

Because adding in repair stuff requires the supplier to provide documentation, frequently training, a parts manifest, guaranteed 10-20 year availability of spares, and probably about 50 other requirements I don't know about.

All of which add up to a rather large contract cost increase.

Possibly this boondoggle will result in the military putting in more reasonable "right to repair" terms in the contract, rather than insisting on the gold-plated thing I mention above, but more likely it will simply result in more cost overruns.

I recently tried a bunch of Office packages and was surprised by just how bad they've gotten over the years. It just feels like a downgrade from what we had in prior decades. Especially LibreOffice just had the most abysmal performance imaginable. The older versions were much better in my experience.
grandinj · 6 months ago
If you have specific performance issues and are able to share the associated documents, please log them at https://bugs.documentfoundation.org/.

Of course, we cannot always help, sometimes the slowdown is due to increased feature or stability or conformance, but often we can improve things greatly.
