Also remember Conways compression- any series of bytes, could be interpreted as the endresult of several conway games, layed over one another with relational operations.

So it compresses titanic data down to some Booleans and chess expressions.

Size: 4096 x 4096 Offset: (0,0) Def: GameA Opening Lib:C3 Turns: 2567

[&] Size: 512x 512 Offset: (12,0) Def: GameB Opening Lib:G42 Turns: 12

[!] Size: 4096 x 4096 Offset: (0,0) Def: GameD Opening Lib: FULL_HOUSE Turns: 0

Its a pretty nifty way to compress files beyond the point of no return, knowing that the deterministic knowledge of the game- allows for a full recreation of any file, given enough processing power and time.

There are of course some attempts to optimize the whole process- having often used game snapshots to fast-forward from and re-wind back too.


If such a particle interacts with the water of my brain- would i drop dead?



If such a baseball would interact with your brain, then yes. That would be kill.

If only the particle interacted: no. It's too fast to reasonably interact with something as short as going through a human body with any meaningful amount of energy.


Im in industry automatization- and its usually that the production is a linear problem- in a tree of linear problems. Meaning any station in the production may show problems after the start.

These come in 3 categorys- full stop (machine breaks/quality so bad production cant continue), solvable (machine can produce at reduced rate) - and hidden (quality problem shows down the line).

Hidden are the meanest problems, because you have to traverse back up the tree to the producer of the problem- solve the problem, which may result in new problems - migrating back down the production line.

Try to not see it as a binary problem of release- not release, but more of a very complex longterm graph traversing problem.


By any chance to you have any good links or books on this kind of thing? So much of continuous deployment winds up sounding remarkably like things industrial automation already has language and studies for.


You can implement a lambda style of programming in lua. Im made a game for the spring engine, where i implemented a simple function to use anonymous functions. Granted it doesent have the lazy computation of a pure functional implementation.

T= process(T,

            function(element)
                if type(element) == "number" then 
                   return element
                end
            end
            )


Hey, it looks like a lot of valid comments of yours are invisible to normal users because they (and you) are marked as 'dead' in the system. I've vouched for as many as seemed valid. You might want to message one of the mods to ask to be marked as undead, or something.


Its still destroying the rails when firing then?

Last time i checked this was the problem indicated- making a rail replacement necessary any x-shots, and erasing the saved volume and weight on ammonition nearly completely.

So what about the obvious TRIZ sollutions?

Make the Rail replaceable? As in build it from a substance that can be recoolected and swiftly reshaped on the fly into a new rail? Some sort of conducting ice that only last long enough to keep the current flowing and the projectile wagon on the rail on its way out?

How about a entirely diffrent approach - seperating rail and conducting? As in, two laser-created plasmachannels with non-conducting rails?

Has anyone observed this project closer?


I think (but don't know since I haven't worked on any of the projects) is that replacing rails every few shots cuts their shot rate down to an unacceptable level. Additionally, remember that these guns are designed for coastal bombardment, must fit on a ship and be served by a reasonable sized crew. Having to add crew members to swap out rails or machinery to swap out rails takes up precious space on a ship. And unless you could reform ten barrels per minute you couldn't keep up with their desired shot rate.

Usually if there is an "obvious" solution they have done at least a cursory analysis of it and found a deal breaker for putting it on a ship. It's not guaranteed, but if there is something obvious to try that would solve one of the major hurdles then someone should have suggested it, and the idea probably had traction until they figured it it wouldn't work. The engineers and scientists working on these projects aren't total greenhorns, they are experienced weapons developers.


I have worked with experienced software developers- and usually nothing new is tryied. You open your previous solution kit, you grab the most viable sollution and slap it on. Ductape. Done.

At best a little research is done at some experienced user forum, where the problem is declared unsolveable.

There is a reason why many unversity undergrads find such "genius" new approaches - its because they usually dont know that the problem is suppossed to be unfixable. Not professionally blinded, was the term, i presume.

Remember this is the same lab, who did send subs intot a world war without properly tested torpedos. If my assumption is right, half of them is traditional explosive cannon engineers, whos life wor would become obsolete on success.


The military acquisition process (of which technology development is part of) is nothing like software development (even software acquisition projects barely resemble the way SV approaches software). It is frustrating to be a part of because of the endless bureaucracy, but during tech development they do indeed try new things. That is the entire point of Dahlgren's existence, is to research new stuff.

Remember that this is also the same lab that gave us the Norden bombsight, which many historians agree was a major factor in the allies winning WWII.


The bombsight is impressive however:

‘In practice it was not possible to achieve the expected accuracy in combat conditions, with the average CEP in 1943 of 370 metres (1,200 ft) being similar to Allied and German results. Both the Navy and Air Forces had to give up on the idea of pinpoint attacks during the war.’

https://en.m.wikipedia.org/wiki/Norden_bombsight


The ineffectiveness of the Norden is overstated, since that's the trendy thing to do right now.

Admittedly, the Norden did not live up to its hype. Almost nothing performs as well in real life as it does under perfect conditions- this is commonly seen when going from the "golden testers" in development that graduated from test pilot school to the "regular testers" during operational test. But once appropriate tactics were developed (this takes a while with all new technology) and they found a few bombardiers good enough to lead bombing formations, it was effective. Not at the level of pinpoint accuracy, but the performance improved quite a bit over the 1943 results. They never took the Norden off the B-17s because any time the Norden had bad results any previous technology would have been worse.

To the point of my prior comment, Naval Surface Warfare Center Dahlgren, the place that is working on the USN's railguns, is the same place where they were able to get Carl Norden's design into a production ready state where 90,000 of them could be made with the precision of a master Swiss watchmaker. Dahlgren isn't staffed by a bunch of software devs that call themselves "engineers" because they think it sounds better. They have real engineers working on solutions to their problems, and a history to back it up. While you can't assume they've looked at every possible idea, they have considered many novel ways to fix the main issues of railguns.


Is it me or am I getting a 'stereo' effect on your comments? Yours has not been downvoted but your 'friends' comment down there is disappearing slowly ...


My assumption is smurf auto hellbaning.


Im very sorry to hear this. I sincerely doubt that any online plattform can change the outcome of a IRL meeting. Networking by definition is not anonymous, so if one gets to know people, the same scenario will reapear again and again. I will try to think about a solution for this.

I must apology for im usually one, vehemently defending freedom of speach. The reason for this is that i love the internet, before the whole world decided to crash the party. It was a great place- insofar, as people who usually would be shunned by society could meet one another and create works- overcoming social isolation.

Let me expand on this- they guy who lifes over the street from my aunt. He is nuts, never goes outside, except at night to smoke - where he runs screaming in panic, should anyone on the street come even close to his door. In some poorer country he would be homeless- and for society useless. Now turns out that- even with shizophrenia - he has a state that cares for him- he has a sister that cares for him, and he has the internet, to work and communicate. And thus he can contribute to academia. Now, such a social mess- will never fullfill the needs for a social silod suburbia, in fact he cant. So if i promise to try to solve your networking and integrating problem- will you stop trying to harass the social misfits and otucasts who are incapable of fitting in?


Its a protestantic thing. If you have sinned, as in you couldnt keep your behaviour under controll- you must suffer and punish for your sin and repent.

Its the same thing that creeps into every drug discussion. Its one of those caddisfly larva conglomerates, where people glue lots of pseudo science onto theire "feel-good" opinions instead of really trying to solve the issue with realistic solutions.

You could sell the realistic solution to these individuals by telling how much the "sinners" suffer after the operation and how heartily they regret taking the left hand path.


If you are depressed- buy a horse.

Isnt it wonderfull how we can fix depression now, but nobody has worked on a chemical fix against beeing overly conformist behaviour? No legal drug on the market that cures a lack of rebellion.

Mysterious.

As if what is declared disease and what is declared cure, is dependant upon how usefull it is to society- but wait, rebellion could be usefull for a scientific society too- so its dependant on how adaptable the "cure" makes you for a hierarchic society.

All those pheromones the queen emits, they make the little bees work.


- and when everbody is special- noone is, and looking at them on facebook becomes uninteresting.


Its enough to just plug in a cable into two switch ports.
