I couldn't get the network load balancer working. I have multiple MySQL instaces, the straight forward solution was to use a multihost connectionstring, but MySQL Connector/Net had a bug, and was not working with multiple host...

@pacmaninbw Modern compilers are so forgiving, it's hard to say what does and doesn't break C nowadays.
Half the things are undefined behaviour anyway.

How seriously can we take the "viewed" figures shown? There seem to be some extreme artefacts, enough for me to doubt them. eg several of my questions have view counts which grow at "a few views per hour", and then they suddenly (within one hour) jump by several hundred or even thousand. Not credible?
 
7:56 AM
@OliverSchonrock usually the view counts are at least semi-accurate from what I know
It's public knowledge that not every pageload counts as view and that the views are tied to IP in some way shape or form

Q: Python Implementation of Canopy Structural Dynamic Model using scipy.optimize.least_squares

ABCI am using the least_squares() function from the scipy.optimize module to calibrate a Canopy structural dynamic model (CSDM).

Q: Best way to return a pdf from a pyodbc row in flask?

Alias_KnaggI have figured out two ways to return a pdf from a pyodbc row with flask.

I was hoping the later version would avoid loading the whole pdf into memory, but I now realize I ...

Q: Matlab: Vectorizing equations for fsolve

@OliverSchonrock if your question becomes a hot network question like "high-performance-txt-file-parsing" the view count is expected to jump high
 
"hot network question"? Is there such a "flag or status"..which is reached at some point? That would explain it perhaps
 
There is a little clock below the vote buttons which will show you the timeline of your question. There you will see Jan 9 at 4:22 history became hot network question
Nobody, at least no normal user, knows the trigger of when a question becomes a hot network question.

If your code works and you just want someone to review it, you should post it over at Code Review instead. — Magnus Eriksson 35 secs ago
1) This post should be moved to codereview.stackexchange since it is a working code and you want improvement. 2) Its a bad pattern to have conditional behaviour in your unit tests. Define two parametrized tests if you need to have two cases. 3) Unit tests don't check for NOT throwing exceptions, this a bad approach. — Neo 42 secs ago

You may also want to edit your code block; I can't drop it in and test it (this isn't the Code Review SE site) or give feedback on possible changes to your methodology when it's unclear how you're going about it.
