bash - How to launch tmux with pre-opened second window and execute commands? -

-

there's possible duplicate it's closed , unanswered.

as i'm using chef automation, nice automate tmux launch pre-launched python web server , second window opened. (this development environment). , way of doing specifying parameters command line.

commands want execute in window title "daemon":

source bin/activate cd project debug=1 python app.py

i'm unable find command line parameters allows pre-execute commands when launching tmux, , open more windows on launch.

you want create session without attaching (using -d option), can send additional tmux commands open second window before attaching.

tmux new-session -t mysession -d 'source bin/activate; cd project; debug=1 python app.py' tmux new-window -t mysession tmux attach-session -t mysession

ok , searched more 4 days , more 20 posts here in stach or in websites without kind of success first here htaccess file rewriteengine on rewriterule ^([a-za-z0-9_]+)/?$ index.php?page=$1 [nc] rewriterule ^([a-za-z0-9_]+)\/([a-za-z0-9_]+)\/?$ index.php?page=$1&action=$2 [nc] i tried many codes 1 worked me can call request , works me www.example.com/pagename => www.example.com/index.php?page=pagename here questions , please provide me information "in detail" understand code well 1- how convert request automatically www.example.com/index.php?page=pagename www.example.com/pagename 2- if tried add slash @ end shows me page without images or styling mean www.example.com/pagename => works www.example.com/pagename/ => doesn't work that's :) for first part need 301 rule this: rewritecond %{the_request} /index\.php\?page=([^\s&]+) [nc] rewriterule ^ /%1?

C# random value from dictionary and tuple -

-
i have following code, , need random item contains string "region_1" dictionary. public static dictionary<int, tuple<string, int, currencytype>> itemarray = new dictionary<int, tuple<string, int, currencytype>>() { { 0xb3e, new tuple<string, int, currencytype>("region_1", 1500, currencytype.fame) } }; public static int generateitemid(string shopid) { var generateditem = itemarray.elementat(new random().next(0, itemarray.count)).key; } how select this? it's not possible efficiently... first create static random @ class level... prevent non-random behaviour if run query on short period of time... (it's seeded discrete clock) static random rnd = new random(); then: var item = itemarray.values .where(t => t.item1 == shopid) .orderby(_ => rnd.next()) .firstordefault()

algorithm - Testing tetrahedron-triangle intersection -

-
i want determine whether given triangle intersects tetrahedron. not want compute solution polygon(if exists) itself. there library/package/published practical algorithm can used solve problem directly (unlike attempt below)? i think last resort have use standard polygon-polygon intersection algorithm implementations solve problem indirectly . my attempt on problem: thought of breaking problem of polygon-polygon intersection. each triangular face(say t1 ) of tetrahedron , given triangle t2 , thought of doing following: compute intersection(a line) between planes corresponding each triangle, l1 . for each triangle: for each edge of triangle l2 , compute point of intersection p between l1 , l2 . test(maybe using parametric form) of l2 , if point lies on edge l2 . if both triangles t1 , t2 , there exists at least one edge on intersection point p lies, implies triangles(and hence given tetrahedron , triangle t2 ) do intersect. create orthonormal fr
