case insensitive files systems and git – Lesson Learned – I Can’t Get My Git Repo Clean! | DrupalEasy

One file kept getting added to the git modified list: service/src/main/MySOAPdefinition.pas.
It was part of a repository that had been migrated from SVN (more on that in a future blog post) and along the way been renamed in directory service/src/main from MySOAPdefinition.pas to MySoapDefinition.pas. SVN (and TortoiseSVN) don’t object to this. But git does.
You’d see this on the command-line:
>git status
On branch develop
Your branch is up-to-date with 'origin/develop'.
Changes not staged for commit:
(use "git add ..." to update what will be committed)
(use "git checkout -- ..." to discard changes in working directory)
modified: service/src/main/MySOAPdefinition.pas
no changes added to commit (use "git add" and/or "git commit -a")
>git add service\src\main\MySoapDefinition.pas
>git status
On branch develop
Your branch is up-to-date with 'origin/develop'.
Changes not staged for commit:
(use "git add ..." to update what will be committed)
(use "git checkout -- ..." to discard changes in working directory)
modified: service/src/main/MySOAPdefinition.pas
no changes added to commit (use "git add" and/or "git commit -a")
Basically the add would do nothing.
On Windows, this is how to get around this:

Latency Numbers every Programmer and Architect should know
Posted by jpluimers on 2016/07/06
Via +Martin Blais, Philippe Beaudoin, Lars Fosdal as Useful resource……:
Hit the cache, Jack…
Interactive Chart of Latency Numbers every Programmer Should Know (from 1990s until 2020s including script to draw the cart).
Also, this variant by Erik Meijer from Coursera (https://www.coursera.org/course/reactive): https://d396qusza40orc.cloudfront.net/reactive/lecture_slides/Latency%20as%20an%20Effect%201.pdf#page=10
Via Asbjørn Heid:
Following up on +Lars Fosdal’s earlier post here’s a talk by Herb Stutter which goes into more detail of where the performance is these days.
It’s a general talk, not C++ specific. Recommend it to get some idea of what goes on under the hood these days, and so one doesn’t try to do some premature optimization which may turn out to be bad.
