Shake it baby, you wanna dance

I really love everything related to Cosmology but I always struggle with two contrary concepts that lead to paradox (for me) :

- Infinity : from school, we learn our universe is infinite.

- We often do calculation with upper limit like this one : 10^240. This is a big number butttttt it's not infinite you know. 10^240+1, 10^240+2...

So :

1. if it's infinite, why doing upper limit calculation ?

2. if it's limited, what is there outside that limit ?

Extremly paradoxal


People say the universe is "infinite" because spacetime's curvature is, as far as we can tell, flat, and so it should continue in all directions without ever wrapping back on itself (unlike, say, the Earth, which has spherical curvature).

But practically it's finite because we are only in causal contact with things up to 13.7b ly from us, and given space appears to be expanding at an accelerating rate, we probably will never get into causal contact with (almost all of) the part of the infinite universe outside of our light cone, even though things ought to exist over the "horizon". So only a tiny infinitesimal sliver of the infinite universe is knowable by us.


This is the type of diagram that horrified me.

It's a very very hard and time consuming task for dev to maintain hotfix for previous releases !

Yeah, easier for users, they don't have to care about breaking changes or migration guide. They just blindly update to the nearest minor.

But as the time goes on, the code for dev ends up being a complete mess of git branches and backports. Dev finally forgot some patches and the software contains a major security hole.

Dev ends by being exhausted, frustrated by its project and roasted by its users.

=> What I do : do not maintain any previous release but provide a strong migration guide and list all breaking changes !

users just have to follow updates or use another software.

I'm happy with it, my project has no debt code and more clean code.


Yes, the original git-flow post aggregates several widely-held intuitions about git, and then shoves a bunch of fluff in the middle to make it look more appealing to middle management.

I have seen firsthand how the original git-flow post convinced management to move off SVN. In that regard, it's an extremely important work. I've also never seen git-flow implemented exactly as described.

...and frankly, there are better ways to use git anyway. The best git workflows I've seen, at small scale and large, have always been rebase-only.



Seriously, I really appreciate that article, explaining a lot a thing we see that news are able to understand and explain.

God job


> So i feel like this might be the most overhyped project in the past longer time.

easy to meter : 110k Github stars

:-O


All links in the top navigation are broken (404).


Sorry about that. Noticed the footnote was broken.

Fixed the footnote, broke all other links. Should be OK again when the caches catch up.


I like the way of thinking. Instead of migrating to another database, they keep that awesome one running and found smart workaround to push limits.


It is what mature engineering does. Migrations are not fun.


Nice

IMO, the answer does not come from the bot answer, but in the questions I had. Every new question was a confirmation of how I feels about my projects.


Awesome !! Some month I'm trying to find a free game to learn playing Go with my young son.

Thanks for this !!
