php - schema file hosting ftp server -


i interested in structure of file hosting services how works multiple server see schema?

i don't know if it's possible?

enter image description here

original size :schema.jpg

schema:

  • client upload file (file.txt) on principal server
    • server check server space reached , move server#1
    • upload file.txt server#1 and
    • saving info in database server#1/file.txt
    • return info links client..

but in upload.php how change ftp info multiple server?

of course, vision.

i don't know if it's if file hosting works.

so if think idea not good, thank sharing knowledge?

take @ hdfs. clustered filesystem (though geared towards use cases when intensive computation needed on large sets of data) seems close you're describing.

the way solve connection issue, have custom service acts similar ftp (it supports commands put , get) allows connect cluster generically , sorts out put it.

linux - xterm copying to CLIPBOARD using copy-selection causes automatic updating of CLIPBOARD upon mouse selection -

i've tried various ways coerce xterm (versions 285 , 292) copy selection clipboard clipboard whenever press ctrl-shift-c. promising way far has been, in ~/.xresources, put this: xterm*vt100.translations: #override \ ctrl shift <keypress> c: copy-selection(clipboard) \n\ ctrl shift <keypress> v: insert-selection(clipboard) ctrl-shift-v works perfectly, copying has nuance... if restart xterm, highlighting text puts things in primary clipboard; expected, proper, default behavior. if hit ctrl-shift-c, copies current selection clipboard clipboard. the bug, however, if highlight text after first time pressed ctrl-shift-c, you'll see highlighting copies both primary and clipboard. cannot figure out how stop xterm updating clipboard upon selection... , doesn't make sense me in first place. i said, @ specific point in time, copy selection clipboard... yet starts updating automatically upon selection after doing once... anyone have workaround...
