Planet Satellite: British super-plane or magnesium flop? (2015)

Many years ago had my first Gopro camera that seriously overheated, sent it for repairs, they said there was nothing wrong with it. It literally turned too hot to handle after taking a few clips and wouldn't work. I think there was some serious hardware issue that caused it to then drain the whole battery.

Gave the brand a second chance some years ago. Couldn't export my videos from the app, it always hanged. So I couldn't share footage. Apparently a common long standing problem on forums.

Woved to never buy anything from them again.

One can try putting themselves sometimes in the position of an old person. Let's say you have a heavy steel rollator with grocery bags hanging from the handles. You've spent an hour going to the store in the summer heat and are quite exhausted. Now try to enter your building. There's locked door that needs to be held open, and two thresholds, one for the platform in front of the door and one for the door. You can't go over the first threshold with your rollator as that would prevent the door from being opened.

Now, I think the assumed way to get in is to keep the door open with your body while simultaneously lifting the rollator over both thresholds. This requires considerable strength, as you have to reach far with a heavy weight. Maybe an athlete could do it. Not an old exhausted person.

An old person needs to first leave the rollator out, open the door and make it so it stays open with a hook. Involves crouching and working with your hands close to the ground. Then lift the rollator one by one over the steps and go inside. Then come back out and close the door.

A foot operated door stopper and a few slopes could probably ease that up tremendously.

I think it's an accurate description of a common way of thinking, though I wouldn't call it conservative in the global sense.

Another is some of the domestic manufacturing or hard tech movement people who present lofty ideals about jobs and sovereignty and so on. But there's a claim that when the surface is scratched a bit, it devolves into a want to keep their imported cheap input materials tax / toll free while introducing taxes and tolls to their foreign competitors' end products. I mean who would pay for domestic materials, they're much more expensive, there'd be no margin!

It still seems to me designing applications or web services is so hard that it's just easier to hire thousands of people to do customer service and having people to come physically to do things. The average corporation's business application or web page is absolutely terrible and a lot of non-technical users simply can not do business with it. Ie it is a hindrance for the businesses core reason of existence. Do the QR code things show up in revenue tracking? Do they do A/B testing? I think I prefer to choose another restaurant if I see that, or not come again.

I think some small pizza shops have had proper simple web pages, probably because it's do-or-die for them and the person contracting the web page is the person also knowing very well how the business is doing. Also phone interactions are very fast and straightforward. It's sad to see them having to struggle with terrible card payment terminals and everybody trying to take a cut (credit card and delivery companies).

I see two really good ideas for monetizing the free tier for consumers.

Firstly, if the user is asking for things where AI can link to products or services to buy, there's a very good relevancy, much higher than in other types of ads.

Secondly, since the AI often takes time to compute answers to user's questions, they could be shown ads while waiting. People could perhaps be less annoyed by this than some other commercials since they know the break has to be there anyway.

(First idea is something I came up when asking Claude to compare some products, or ask for help in lawn care. Second idea was by a colleague.)

Ramjets were developed right after the second world war and Mach 4+ was reached in the fifites. It's complicated but not extremely. See Antonio Ferri or Lockheed X-7.

It turned out out solid fuel rockets are operationally more practical for the use cases like air defence, long range missiles that are ballistic instead of cruising in the atmosphere and so on. And jet engines are more efficient for subsonic cruise missiles. Ramjets are still used in some missiles like the long range mach 3 air-to-air Meteor.

I think there's also some exaggerations about the differing highway landing capabilities of various aircraft. [1] is a video showing Eurofighter, F/A-18 and F-35 all landing on a highway in an exercise. Capability with stores and fuel load is another thing but I've read material that doesn't find the contemporary aircraft drastically different in that regard. Now, maintenance hours per flight hour and general operability certainly are interesting topics and there could be large differences.

As a native non Indo European language speaker, aware of the many differences to Indo European languages, it is noteworthy that this however is similar in both. Oikea ja vasen, right and left. Oikea ja väärä, right and wrong.

In clothing you have the right side and the reverse side while here it's oikea ja nurja. Again similarities but nurja has this twisted and dark connotation. Or upside down = nurinperin.

Does anyone know if there's ever been any sort of proper retrospective why the forestry policies of many countries have been so disruptive. Ie supposedly the most organized, high trust, low corruption and scientific societies in the world like Finland and Japan have done some very drastic and unnatural forestry measures that cause effects to this day. It is different than some countries where rampant illegal logging has just destroyed the land, sure. But it's been terrible in other ways. Destruction of biodiversity, destruction of water. In Finland at least the policies have been absolutely forced by law and have sent people to prison and mental institutions. And the land and future generations will suffer for a thousand years. And now some of the policies have been completely reversed - as if nothing had happened. It's this completely parallel bizarre world.

Could we at least look at these tragedies honestly and openly, and learn something from them.

Yes, sorry, my criticism was meant to be directed at Burke, since the thermos comment has always bothered me.

You're correct about payload fairing. Also, Space Shuttle External Tank was spray foamed, causing the Columbia disaster when a piece of foam from the tank with hit the wing leading edge. I was googling for what the final verdict was but couldn't easily find an answer. Nice summary in [1]. Cryogenics are complicated.

Yes, sure, it won't solve everything and wouldn't be perfect.

In a corporate environment, if you can measure something with a number, then you can set a target and pass/fail criteria and so on. Developers' personal opinions of some code base's quality are harder to build corporate processes around.

There's things like integration tests and static analysis. Of course again, not foolproof and don't solve all problems. But they help. Especially in a corporate environment where you need all the mechanisms you can get to prevent skimping on quality.

Organic farming, at least over here, has also wellbeing criteria besides just controlling the food. For example a lot more space per animal, ability to go out and so on. Organic meat is a bit more expensive, but not hugely. So it shows it can be done.

I wonder if there is some easy way to have a "spaghetti index" of a codebase. One could then have different criteria for different projects / parts of projects. If it's a business critical thing that also expects to see a lot of future development, one could then communicate to management that the spaghetti index is too high and that must be first lowered before further development can happen. And on the other hand, if it's a throwaway tool that's used for a limited time, no matter.

To reciprocate the naming of Wine, maybe it could have been named Line. Also, both have this positive clang, being associated with "having a good time".
