Please share with me your method(s) of determining a specific location's timezone.

Hi folks; hope all is well.

If, for whatever reason, you must determine the timezone in which a location resides, how do you go about acquiring the information? You have the location's address.

The solution seems trivial on the surface -- query some existing location service; query an existing geo database; etc... -- but, as often the case, things aren't always trivial; or they are that trivial and there exists many solutions. So, as I'm doing my research, I'd like to have your input/enlightenment.

I appreciate your time.

[AF] How to use a docker image of flask on an instance

I am trying to use [this](https://github.com/tiangolo/uwsgi-nginx-flask-docker/tree/master/python3.6) docker image of flask with nginx and uwsgi on an amazon ec2 instance. I am following the readme in the same github repository.

I am really new to this, so I have no idea how this is supposed to look or what obvious stuff I am supposed to do beforehand. I copied all the files in the github above to my instance, so my directory looks like [this](https://i.imgur.com/fDnkiOH.png). I ran `docker build -t myimage .` and `docker run -d --name mycontainer -p 80:80 myimage. `docker ps -s`looks like [this](https://i.imgur.com/6cpDjrM.png). Yet when I go to my website [here](http://ec2-18-217-22-81.us-east-2.compute.amazonaws.com/), nothing shows up. I have done nothing else. What am I missing/doing wrong?

pomegranate v0.9.0 released: probabilistic modeling for Python

Howdy all!

I just released a new version of pomegranate. The focus of this version is on missing value support for all models in both the model fitting, structure learning, and inference steps for all models (probability distributions, k-means, mixture models, hidden Markov models, Bayesian networks, naive Bayes/Bayes classifiers). The general manner that this is done is by only collecting sufficient statistics from observed values, and ignoring missing values. This can frequently achieve better results than using common, simple, imputation methods.

* I've added documentation to the [readthedocs page](https://pomegranate.readthedocs.io/en/latest/) under the "Missing Values" section
* I've added an [extensive tutorial](https://github.com/jmschrei/pomegranate/blob/master/tutorials/Tutorial_9_Missing_Values.ipynb) on how missing value support is handled here
* I recently [gave a talk at ODSC west](https://www.youtube.com/watch?v=oF8BKWe9_i8) about pomegranate and the features recently incorporated (sadly before missing values were added).

The modular nature of pomegranate means that one can now use missing value support in conjunction with any of the other features. For example, one can easily add multi-threading to speed up models, or do out-of-core learning with incomplete data sets, or have both missing data and missing labels to do semi-supervised learning with missing data as well!

You can install pomegranate either by cloning the [GitHub repo](https://github.com/jmschrei/pomegranate), or with `pip install pomegranate`. Wheels should be built for all platforms soon, but some issues have delayed that. I hope to have them up soon, so you don't even need to deal with Cython.

As always, I'd love any feedback or questions!

Best practices for building an API consumer? Is it good to have a different class defined for each end point?

I am working on a project that displays stats about users for the game Destiny 2. Part of it consists of lots of API requests for pulling in data about the users. I will be dealing with about a dozen different end points at the server. I'm new to django/apis, and wondering what the best strategy is for structuring things. I have not found much of anything written on this topic.

The big decision point I am facing now is whether to create an object corresponding to each end point. For instance:

class GetProfile:
base_url = 'http://destiny.core/getprofile/'
self.response = { }

def make_request(self, parameters):
<create session, make request, return response>

def extract_profile_data(self, response):
<pull pertinent information about user>

And I'd have one of those for each endpoint, e.g., GetUserStats.

I guess a key question is, What am I using this for? I am using the data to fill the database for a django project, so it will all go into model instances. Unfortunately, there isn't a 1:1 correspondence between endpoint and models: most model instances draw information from multiple endpoints. It seems objects like the above could provide useful as a container of information about a request, as well as methods for working with them.

Why am I asking this question at all? One random person online said that the above strategy is redundant, that responses in the requests library have enough structure, and urged me to just get the data and fill your database using more procedural programming. I feel like that person is wrong, but I am noob enough to really not be sure.

I just wanted to check in and see if there's any hive wisdom about this, obvious pitfalls or whatever, before I make this major design choice for my project.

I am wondering if this book is worth buying? I have been reading the free tutorial and it is very good learning tool so far, better than the documentation because it is human readable.

Shared db with restricted views per user.

I have a db that is to be shared. Where if a specific object has a certain value I need specific users to be able to see and edit it. No other users can see or edit these objects.


I am trying to understand what way one should do this. I don't know django very well. I am currently looking at conditionals for views. Not sure if that is even possible given i don't know if conditionals on views can filter objects from models.


If anyone could point me in the right direction I would greatly appreciate it.

The power of class based views

So the main (or one of them) reason to use class based views is to be able to display a list of objects in IndexView, and the details of that object in DetailView. But what if after the user clicks on an object in IndexView, I want to display another list of objects, and then when the user clicks on that, it will display details.

Example:

IndexView display's a list of categories. When the user clicks on a category it will display a list of sub-categories. When a subcategory is clicked, it will display details of that subcategory.

Thanks and sorry if my question is to basic!

[AF] Where do you store abstractions for Redis commands? Same models folder as DB?

Hey everyone, I'm curious where you store functions that abstract out calls to redis. For example, I'd rather have a command like `active_users = get_active_users()` in my API controllers than long & ugly `active_users = json.loads(r.hget('users', 'active') or '[]')`calls. It feels to me like these should be organized alongside your models, but I'm not sure if this is common practice... or even what the common practice even is.

Thanks for any insight you can provide!
