QUESTION
I've been trying to use ADLINK's Vortex OpenSplice Community edition with the Python API (python version 3.6 within a PyEnv virtual environment) on Ubuntu 20.04.2 LTS. I've followed the PythonDCPSAPIGuide and got the python examples in ($OSPL_HOME/tools/python/examples) working. However I can't figure out how to create a topic associated for a domain participant for a statically generated topic class using idlpp
. How would I be able to do this?
I have an IDL file that has include paths for quite a few other IDL files. I have converted these IDL files to a python topic classes using the following bash script:

I'm trying to create a sort of "vortex" downward vector in my Tikzpicture diagram. I looked up similar code for bending vectors, but don't know how to particularly change the details too well. I attached an image of what I am trying to attain and drew it in with red. I would attach code, but the entire diagram is quite lengthy. If someone could explain more how to bend the vector in a particular direction.

Answered 2021-Mar-23 at 03:51First of all, Numba can perform parallel computations resulting in a faster code if you manually request it using mainly parallel=True
and prange
. This is useful for big arrays (but not for small ones).
Moreover, your computation is mainly memory bound. Thus, you should avoid creating big arrays when they are not reused multiple times, or more generally when they cannot be recomputed on the fly (in a relatively cheap way). This is the case for r_0
for example.
In addition, memory access pattern matters: vectorization is more efficient when accesses are contiguous in memory and the cache/RAM is use more efficiently. Consequently, arr[0, :, :] = 0
should be faster then arr[:, :, 0] = 0
. Similarly, arr[:, :, 0] = arr[:, :, 1] = 0
should be mush slower than arr[:, :, 0:2] = 0
since the former performs to noncontinuous memory passes while the latter performs only one more contiguous memory pass. Sometimes, it can be beneficial to transpose your data so that the following calculations are much faster.
Moreover, Numpy tends to create many temporary arrays that are costly to allocate. This is a huge problem when the input arrays are small. The Numba jit can avoid that in most cases.
Finally, regarding your computation, it may be a good idea to use GPUs for big arrays (definitively not for small ones). You can give a look to cupy or clpy to do that quite easily.
Here is an optimized implementation working on the CPU:
QUESTION
my code was working perfectly before and then when I ran flutter upgrade and downloaded the newest version, everytime I try press the button to move to the next page. I get a "Exception caught by rendering library error.
This is the error I get
...ANSWER
Answered 2021-Apr-19 at 00:45That's because of the null safety
update from Flutter 2.0
There are 2 solutions to solve this problem
First
You will have go migrate all your code for null safety
Second
Downgrade your sdk enviroment version in pubspec.yaml
.
Example : sdk: ">=2.10.0 <3.0.0"
You can choose which one you use, if you want to use null safety choose the first one, if you don't want to use null safety choose the second
This will hopefully help you.

...ANSWER
Answered 2021-Mar-11 at 02:25The correct approach is to use TelemetryConfiguration.CreateDefault() method to load any config from disk, then set/change additional values on the generated configuration.
Once the TelemetryConfiguration instance is created pass it to the constructor of TelemetryClient to create the client and start logging.
QUESTION
I am writing a blade stress routine all input fields should be numeric.
The Claculate button will calclate then sometimes refresh (you can see the table fill out coming from the script) the refresh takes out the table answers and all the filled in values.
When it doesn't refresh I can then print the page or change values and hit calculate again. This is the intention of the HTML App.
Is there spmething that I don't know about browsers?
I have tried on Opera with debug on finish the whole Calc1() funtion then keep tracing goes to Opera code so hit F8 and it will sometimes work sometimes refresh the page. I have tried Chrome Firefox is not working propely on the computer will have to reload it.
