Using git to transfer data via usb stick between Windows and Linux -

-

i trying use git first time in order transport bachelor thesis writing between windows computer @ work , linux computer @ home. because don't have server use usb stick store shared repository. question understand should possible.

on windows system have created working repository , remote repository on usb stick , pushed working directory usb stick. seems working fine.

on linux system have cloned repository, made changes, added them , committed them. far seems working fine. when try push changes usb stick following error message:

counting objects: 3, done. delta compression using 4 threads. compressing objects: 100% (2/2), done. writing objects: 100% (3/3), 264 bytes | 0 bytes/s, done. total 3 (delta 1), reused 0 (delta 0) remote: error: unable create temporary file: operation not permitted remote: fatal: failed write object error: unpack failed: unpack-objects abnormal exit /media/usb-stick-sta/git/bachelor  ! [remote rejected] master -> master (unpacker error) error: failed push refs '/media/usb-stick-sta/git/bachelor'

in /etc/fstab using following options mount usb stick: noauto,user,uid=1000,gid=1000 own files , have verified case using ls -l. sure have tried creating file in directory , removing again, works without problems.

one answers stackoverflow question (unfortunately cannot find again) suggested executing chmod -r g+ws * on remote repository. resulted in many error messages (independent of whether executed owner of files or root):

chmod: changing permissions of ‘config’: operation not permitted

further research yielded files might immutable tried chattr -i * resulting in messages like:

chattr: inappropriate ioctl device while reading flags on config

reading further found not file systems support these attributes. usb stick formatted fat.

any appreciated. in advance.

if repo isn't big, pack tar or zip file , copy usb stick , unpack on other machine. me wrote genbackup script. creates backup tarfile current date , short hashtag in filename.

if cumbersome, keep track of commits , git format-patch in repo on 1 computer. copy patch files usb stick, , run git am on them on other computer.

edit: error, seems me important part;

remote: error: unable create temporary file: operation not permitted

git wants create temporary file, , fails eperm error. looking @ manual page git, , searching "temporary" gives 1 hit: git-unpack-file. unfortunately, manual page program not specify where tries create temporary file. after googling seems git uses tmpdir environment variable. check if set someplace have access to. if doesn't exist set sensible place , try again.

mysql - FireDac error 314 - but DLLs are in program directory -

i getting when trying access mysql database : [firedac][phys][mysql]-314. cannot load vendor library [libmysql.dll or libmysqlld.dll] this did not happen (unchanged) code, however, have upgraded windows 10 , had reinstall delphi xe8, system configuration matter. in order try solve problem, copied both of files c:\windows\sysytem32. when did not seem work, copied them \win32\debug, generated .exe resides. i imagine doing rather stupid, can't see what. the proper solution place driver file (eg., libmysql.dll ) in application's folder, or place installation location in fddrivers.ini file: [mysql] vendor=<folder>\libmysql.dll (recent versions of documentation seem use vendorlib instead of vendor in ini file.) see rad studio documentation topics configuring drivers (firedac) , connect mysql server (firedac) more information.

-
so per documentation https://developer.github.com/v3/repos/releases/#list-releases-for-a-repository get /repos/:owner/:repo/releases should list relases , https://api.github.com/repos/jquery/jquery/releases should list releases in jquery project , not , why ? because repository doesn't have releases. has tags github presenting in releases page. for more clear example, see: https://github.com/hashicorp/terraform/releases which has both releases , tags showing on page, api shows releases: https://api.github.com/repos/hashicorp/terraform/releases
