 22 Apr 2019, Pintaudi Giorgio, Info, switch of MIDAS to C++, how much C++? 
|
Dear Konstantin and others,
our recent discussion stimulated my curiosity and I wrote a small frontend for the trigger board of our experiment in C++.
The underlying hardware details are not relevant here. I would just like to briefly report and discuss what I found out.

If using a synchronous AJAX call, such as "foo=ODBGet("/runinfo/state");", google chrome will prints this to the javascript console:
"Synchronous XMLHttpRequest on the main thread is deprecated because of its detrimental effects to the end user's experience. For more help, check http://xhr.spec.whatwg.org/."

We're using mhttpd for calls that end up working better with asynchronous requests, and we've built up sort of a parallel, asynchronous library using javascript
Promises.

Here is (1) my promisified HTTP request function and (2) a function that uses the returned promises to build an asynchronous, sequential chain of requests |

NIS is traditionally used together with autofs to form clusters of UNIX/Linux machines. NIS is a database
