Programically setting NvOptimusEnablement for Python-based OpenGL Programs

By -

Is there a way to programmically set the NvOptimusEnablement flag for a Python-based application using OpenGL (and in particular, those using Qt) from within the Python script?

All the references I've seen so far - e.g. Programmatically selecting integrated graphics in nVidia Optimus, or https://stackoverflow.com/a/39047129/6531515 - are for C/C++, where the flag needs to be set as a global define which is compiled into the executable, but obviously that won't work in this case.

Are the only options to:

  1. Create a custom Python interpreter wrapper with this flag set (e.g. https://github.com/cprogrammer1994/optimuspy), OR
  2. Force users to explicitly tag Python / pyinstaller-created-binary as requiring the Nvidia GPU per machine they use?

Spring Elasticsearch Operations

Elasticsearch Operations Spring Data Elasticsearch uses two interfaces to define the operations that can be called against an Elasticsearch index. These are ElasticsearchOperations and ReactiveElasticsearchOperations. Whereas the first is used with the classic synchronous implementations, the second one uses reactive infrastructure. The default implementations of the interfaces offer: Read/Write mapping support for domain types. A rich query and criteria api. Resource management and Exception translation. ElasticsearchTemplate The ElasticsearchTemplate is an implementation of the ElasticsearchOperations interface using the Transport Client. @Configuration public class TransportClientConfig extends ElasticsearchConfigurationSupport {   @Bean   public Client elasticsearchClient() throws UnknownHostException {                      Settings settings = Settings.builder().put("cluster.name", "elasticsearch")....

Network Error and Timeout on Authorize.net JS

i am using authorize.net acceptUI.js in order to create a hosted payment form for credit card acceptance. The problem arising now is that, going on the checkout page, I have the following console message: GET https://js.authorize.net/v3/AcceptUI.js net::ERR_NAME_NOT_RESOLVED Which is weird, cause I cannot ping the domain or anything, as my computer cannot resolve the domain. However, this issue is also reported by individual customers and it seems to be sporadically and not happening the entire time, cause i can see other orders going through. Does anyone know how such an error can be caused, or any ideas how it can be resolved? Thanks for your help EDIT: I just checked the A DNS record for js.authorize.net and am getting the following result only: js.authorize.net. 100 IN CNAME js.authorize.net.cdn.cloudflare.net. Doing the same for js.authorize.net.cdn.cloudflare.net. does not return an A Record, unless I specifically instruct to use 1.1.1.1 as DNS server I...
