 03 Apr 2020, Stefan Ritt, Info, Change of TID_xxx data types
|
We have to request of a 64-bit integer data type to be included in MIDAS banks.
Since 64-bit integers are on some systems "long" and on other systems "long long",
I decided to create the two new data types

I received my new 2020 mac book air, so between Stefan and myself, MacOS support for
MIDAS is assured for 5 more years at the least. K.O. |

12 May 2020, Stefan Ritt, Info, New ODB++ API 
|
Since the beginning of the lockdown I have been working hard on a new object-oriented interface to the online database ODB. I have the code now in an initial
state where it is ready for
testing and commenting. The basic idea is that there is an object midas::odb, which represents a value or a sub-tree in the ODB. Reading, writing and watching |

Previously, we had:

All this is very good news. I really wish this were available some months ago: it would have helped me immensely. The old C API was clunky at best.
I really like the idea and looking forward to using it (even if at the moment I do not have the need to) ... |

Hi, if you are not using any VME hardware, then you have no VME address jumpers to
set. https://en.wikipedia.org/wiki/VMEbus

19 Jun 2020, Isaac Labrie-Boulay, Info, Building/running a Frontend Task
|
To build a frontend task, the user code and system code are compiled and linked
together with the required libraries, by running a Makefile (e.g.
../midas/examples/experiment/Makefile in the MIDAS package).

24 Jun 2020, Stefan Ritt, Info, New image history system available

I'm happy to report that the Corona Lockdown in Europe also had some positive side
effects: Finally I found time to implement an image history system in midas,
something I wanted to do since many years, but never found time for that.

For password protection of midas web pages, https is required, good old http
with passwords transmitted in-the-clear is no longer considered secure. Latest
recommendation is to run mhttpd behind an industry-standard https proxy, for

To add. Using https with either openssl or mbedtls requires obtaining an https certificate. This can be self-
signed, or signed by a higher authority, or issued by the "let's encrypt" project.

I reworked the MIDAS Makefile to simplify things and to remove redundancy with functions
provided by cmake.

Please note that you can also compile midas in the standard cmake way with
