Yup, some groups in the conflict have developed some really interesting methods for producing usable parts from off the shelf commercial components.

A stockpile pile of such things is not particularly useful without the ability to source the input. Rounds, spare parts and lubricants.

As well as all the organizational elements needed to make use effectively. None of which can be planned around without a clear idea of goals and the conditions they are expected to be used under. Arguably knowledge and tools to produce such things with limited resources available is more useful than a massive easily targeted stockpile.

For a theory to be useful, there needs to be a way that it can be proven wrong. If there is no way the theory can be proven wrong, then it’s not a theory. Something that can’t potentially be proven false also can’t potentially be proven to be true.

The problem with this kind of off the cuff “but what if” stuff is that not enough thought has gone in to it to even know what could be tested.

I mean, the reality is that they’ve mostly just cannibalised the conservative voter base.

The election results show that they’re not exactly sweeping labor strongholds, a lot of labor’s losses coming from SNP, the greens, lib dems and Plaid Cymru. Which is to say, that the voters aren’t pivoting to the right, they’re just pivoting away from labor.

If anything, it seems like media efforts to shove the voter base to the right, and labor’s effort to chase the media narrative, has just driven traditional conservative voters insane, while making left wing voters pissed at labor for moving so far rightwards.

Thermo dynamics, in short.

In long, because adding some heat recovery system to the engine block would mean decreasing the cooling efficiency of that block, thus making the block hotter, and decreasing the efficiency of the engine. Since the engine makes power based on the differential of heat/pressure from the top of the stroke and the bottom of the stroke. If you make the system hotter, then less energy can be extracted per unit of heat produced from burning fuel. Any energy generation from the waste heat of the block would be offset by efficiency losses in the engine it’s self.

Now, most engines don’t actually extract all the energy they could from that differential, which is why turbo chargers are a thing. They use excess heat in the gas exhausted out of the block, expand it to ambient pressure and temperature over a turbine, that turbine then runs a compressor, and that compressor raises the pressure at the air intake. More air entering the engine in the same volume allows for more volume of fuel without having more fuel than oxidizer to burn it, thus increasing the energy density of the charge, increasing the differential in heat between the top and bottom stroke, increasing power and/or efficiency depending on it’s tuning. But that’s not utilizing heat from the engine block, but heat in the exhaust.

In reality, an internal combustion engine and a turbine operate on the same principle. Make gas hot, it expands and makes a thing move. The difference is just that in a steam turbine, the gas being expanded with heat to do work is steam, and in an internal combustion engine it’s the exhaust gasses of the combustion it’s self that are expanding to do work. In a piston engine that expansion is acting on a linear reciprocating piston, but in a turbine it’s can’t on a spinning set of blades in a continual flow. In the middle there is the gas turbine, where the working fluid is the combustion gas and it’s working on a spinning set of blades, this is what a jet engine is.

It’s not just Reddit, so many companies try and shunt you off a mobile web page and on to their app, despite many apps being little more than a pre loaded mobile web pages.

Why? Because users can modify how they interact with a web page, they can install extensions that modify how the code from the website is run, or just deny web pages access to some other process. There is very little a company can do about that, they have no control on how the user chooses to run the page. But… with an app, users can’t modify how the program is run. No plug ins, no web extensions, no choosing not to run some part of it, just the software as distributed by the company. Meaning full fat ads and complete access to any information the OS will let them have, way easier to make money on users that way.

Technically, it’s possible to alter any program, but it’s very hard if don’t have the source code, and it’s illegal to do so in many cases thanks to section 1201 of the DMCA, especially if you try and distribute that modification or tell others how to do it.

Ginkos are crazy because like, they were the last branch of a dead tree of life, secluded deep in mountain range in central China, likely to go extinct next time there was a significant climatic shift in the area.

And then humans were like “damn, I like this tree, I will plant it literally all over the world” and in all likelihood this just massively improved their chances of surviving a few more million years, since now they’re not liable to get one shot by a single event in the area they’re native to.

I don’t mind phone calls, but do not fucking do a video call. Like, I’m and not done up properly, I am probably walking around doing a chore, also, the quality will be shit because my connection will be questionable.

Audio is fine, you don’t need to see my face to catch up.

Realistically, to alter culture, it is required that the structure of an institution must be modified as well, the personalities and priorities of those who end up leading are selected for by the incentives and structure of an organization. The people who “play the game right” so to speak, end up in leadership and leadership reinforces and defends the structure that got them where they are. But just swapping out leaderships without altering structure and incentives will lead to little change in the long run.

Ultimately nasa does have to play politics to receive funding from congress, that’s always been the case and always will be, there is no space exploration without public funding. That means doing stuff that is exciting to the public and convinces them to pressure congress to support it. I’d argue the flawed issue that has lead to some problems is them playing “job creation” politics which forces them to commit to wasteful facilities and companies that have outlived their usefulness to space exploration.

Completely irrelevant to a discussion of trumps ability to alter election outcomes using the federal executive.

 

I’m aware of things like framework and they’re a cool system, but they’re limited in what chipsets can be used by the mother boards they offer.

I’m thinking in the context of a cheap low spec system that can be handed out for use by a group. Most of the options available are just very pricy.

Maybe something like a SBC would be a better fit since there are plenty of cheap options out there and they can be mounted in a custom built shell with the other needed elements.

A thought that crossed my mind was ordering printed circuit board and just soldering on the sockets and the like, but that’s a very involved process with a lot that could go wrong. Especially for someone with very little experience.

Short of custom ordering from a company that does such things, are there any systems for building a mother board?

This is more out of curiosity about what options there are out there. Any other thoughts people have about custom built laptops or interesting things in that space?

 

I’m looking at various single board computers ( think raspberry pi) to host a server on. Namely for hosting media, an email, and perhaps a web site/fediverse instance/blog/forum on.

I’m under an assumption that a SBC and some hard drives could handle this on the hardware side. Am I totally off the mark? And what kind of os and other soft wear should I consider using?
