the quarks have it own (rest) mass, but quite tiny compared to when you include binding energy (9 Mev vs 900 Mev)

cygwin

you can build also with gcc for cygwin, but you introduce a cygwin.dll (not sure about the name) dependency.

i do not think the bridges did degrade suddenly, you need decades of neglect. so this is not work of one major.
<quote>C++ for example, is a hard language, but the learning curve is ... progressive (rise bit by bit).

Rust on the other hand, is like climbing a cliff </quote>

c++11+ is a hill that is so freaking high that you do not see the top.. like Olympus Mons.

honestly i do not see much difference in learning c++ or rust - in order to write good programs you should know most of the c++ standard and that's a lot to absorb.

that's so last century... now we believe that 'nobody needs a quantum computer at home'

i must say i find it very interesting and maybe a bit ironic that nt is built on pirated sources (and architecture)

it seems to me that x86 assembly is the less readable kind of assembly. i always found powerpc set more thought through.
Re:The Art of Kimchi (2009) on Thursday June 07, 2018 @08:45AM (#17255253)
i live in the sauerkraut region, so i inherited the sauerkraut clay pot, but betrayed local customs and started "farming" kimchi instead. it's so much more interesting in taste and not that hard to prepare (when in hurry you can prepare ~5kg in an afternoon).

one day i wanted to be cheeky to my 2-yo son, so i offered him a bit. to my amazement he gasped, but wanted more and more. weird :)

having you here i'd like to take the opportunity and to ask about tetraquarks. if i recall correctly there have been several identified tetraquark particles over past years (many of detections coming from LHC) with hint of possibility of pentaquark.

i always wondered how does standard model includes/describes these?

that was not possible when i tried it, thanks for pointing it out

Re:Why Create a New Unix Shell? on Thursday February 01, 2018 @01:02AM (#16279889)
you can turn windows into an adult computer by using cygwin (maybe mingw), autohotkey and something like window manager.

the illusion is almost real, because sometimes i also run linux in vmware/docker/... and when i am not paying attention i forget easily which os i am on.

the unix subsystem for win is quite boring as you can't mix windows applications with linux ones, for example running visual studio build from bash.

powershell would be probably worth learning, if i'd have to, but i do not. it may be godsend to win sysadmins though, as classic cmd is a 40 year old joke.

they spy on you. in one studio there was a system that monitored yout kb/mouse inputs and logged an automatic pause into the billing system if there were no activity on your inputs.

10+ years, working in 3rd or 4th game studio.

no issues, but with certain employers the crunches can be quite intensive. escpecially when promised 'relief after crunch' never really comes.

with decent employer and if you like math and coding as such, it's an amaze-balls (i believe is the expression) job to have: very broad spectrum of problems that the coding of the games involve and almost free hand in realization and the best part is that performance and memory really matters, and there's no way around it. what i like the most is lower level (sometimes significantly) of corporate bullshit, and that's true even for bigger studios. it's a bit like in quantum physics: "shut up and calculate!" except we code.

<quote>but how the oceans did not boil or evaporate off like they did everywhere else.</quote>

gravity and magnetic field? if it were hydrogen or helium it would be stripped off by solar wind (storms) like everywhere else, but water is quite heavy due to the oxygen.

also 'everywhere else' means practically mercur, mars and asteroids (moon). no idea about venus. ice giants keeps their water also due to gravity and far apart on pluto it's frozen like rock.
