QUESTION
I am new to JS/Vue. I am trying to make a dynamic search input. I am filtering on input change, filtered is an array of objects fetched from my API. The weird thing is that the computed method does not return any data unless I use this.term before the return, it can be a console.log() or anything else with my v-model. What am I missing ?
ANSWER
Answered 2022-Feb-05 at 15:17It's because stops isn't in your Vue data object, so it can't react to changes. Move the loading logic into the mounted method, add a stops property to the data object, and set it using this.stops = ... in the mounted method:
QUESTION
I created a map with osmWebWizard.py and that's working well in Sumo. When importing it in veins example and hit "Play/Start" on the simulation nothing happens until I also hit the Start button in Sumo-gui as well. If I never hit it in Sumo, QTenv is going to "Not respond" or crash. Why is this happening? Can it be changed manually?
Also obstacles are not being recognized as expected, although the *.poly.xml file exists and also I've built myself with polyconvert function. That's why I also tried GatcomSUMO but on my system is not working very well, I'm on Linux, while in the video Windows is being used and the process seems pretty straight forward. After a series of warnings I'm getting an error. Here is the log:
...ANSWER
Answered 2021-Dec-05 at 10:57To allow QTenv to run both Omnet++ simulation and SUMO it's important to set the parameters in the *.sumo.cfg file. By default osmWebWizard tool is pointing to the *.view.xml file, which is left to be modified by the user.
The solution is to add the following lines in the sumocfg file:
QUESTION
I have a bunch of names from the web (first name, last name, of people in different countries). Some of the countries have statistics on how many people have each last name, as shown in some places like here.
Well, that Japanese surname list only lists the top 100. I have other lists like for Vietnamese listing the top 20, and other lists the top 50 or 1000 even in some places. But I have real name lists that are up to the 1000+ count. So I might have 2000 Japanese surnames, with only 100 that have listed the actual count of people with that surname.
What I would like to do is built a "faker" sort of library, that generates realistic names based on these statistics. I know how to pick a random element from a weighted array in JavaScript, so once the "weights" (number of people with that name) are included for each name, it is just a matter of plugging it into that algorithm.
My question is, how can I "complete the curve" on the names that don't have a weight on them? That is, say we have an exponential-like curve sort of, from the 20 or 100 names that have weights on them. I would then like to randomly pick names from the remaining unweighted list, and give them a value that places them somewhat realistically in the remaining tail of the curve. How can that be done?
For example, here is a list of Vietnamese names with weights:
...ANSWER
Answered 2021-Aug-04 at 09:34I'm no mathematician, so I've simply fitted the data to a y=A*x^B equation using these equations, although Wolfram has some others that might fit your data better. Perhaps some papers around the distribution of (sur)names might hint at a better equation.
Nonetheless, the current prediction doesn't seem too bad:

Answered 2021-Jul-23 at 09:08Personally I would keep them in a dictionary.
input_values.to_dict()
And then reference from there.
You could try adding them to local environment like so locals().update(input_values) but I wouldn't encourage it.

Answered 2021-Jul-12 at 14:38It may be possible to leverage fixed width format here. You can read in the entire file, with the widths specified to properly grab the 3 columns you want, then filter out non-numeric values from the first row.

guys, I am trying to make filter by using id's of item. I have researched a lot, but I think I am missing something obvious. So as I said i need to make a filtration, I have API where two different models Transport and Marshes. Each clasess contains id of bus, tram, subway. For the bus id = 1, for tram = 2, for sunbway id = 3 and for each of these separate id's API contains the 3 separate list of bus' numbers, tram's numbers and subway's train numbers.
I create two models and two screen:

Install tram
You can use tram like any standard Python library. You will need to make sure that you have a development environment consisting of a Python distribution including header files, a compiler, pip, and git installed. Make sure that your pip, setuptools, and wheel are up to date. When using pip it is generally recommended to install packages in a virtual environment to avoid changes to the system.
