kandi X-RAY | concur Summary
A brand new client side Web UI framework for Haskell that explores an entirely new paradigm. It does not follow FRP (think Reflex or Reactive Banana), or Elm architecture, but aims to combine the best parts of both.

QUESTION
I have a table called user_table with 2 columns: id (integer) and data_value (integer).
Here are two transactions that end up with the same results:
...ANSWER
Answered 2022-Mar-31 at 14:29Both transactions lock the same two rows, and both can run into a deadlock. The difference is that the first transaction always locks the two rows in a certain order.
If your objective is to avoid deadlocks the first transaction is better: if you make a rule that any transaction must update the user with the lower id
first, then no such two transactions can deadlock with each other (but they can still deadlock with other transactions that do not obey that rule).

QUESTION
We have so far used Databricks for Data Engineering and Data Science purposes but recently have started exploring the new Databricks Sql analytics as we have a lot of SQL Analysts who also want to join the bandwagon (for some use cases).
However, the big stumbling block I have noticed is that a SQL endpoint always needs a Service Principal for Azure Data Lake Gen2 access. There is no option to just use “credential pass through “ without using a SPN.
I have tried looking up the limitations (known issues)page as well as all existing documentation but have not come across anything regarding this.
Can’t we just use a High Concurency cluster with credential pass through for data lake gen 2 (or a single user standard cluster with credential pass through) without using any spn at all (just like we do for data engineering and data science workloads)? Or at least a timeline?
This really is important in regards to fine grained security requirements in organizations for accessing Production data .

How can I rewrite the Axios promise module with only async/await syntax? Please I'm new to Axios & promise, async syntax => what should i put inside the .push() ?
...ANSWER

isn't the best choice here for clean code because while it allows pushing functions that return a promise, it itself doesn't return a promise, so you'd always be forced to use new Promise
at some point and resolve
it in its success callback or at the end of your own code. I guess that's the main reason why you are stuck with improving this code.
I recommend using p-limit
instead. It works like this:

QUESTION
I'm having several problems with my Cloudflare + NGINX configuration together. There are some websites that work for me and others that don't work, with the same configuration in the server and in Cloudflare. So the main problem I have is with the domains that don't work is that they keep redirecting to HTTPS when it is not configured either in Cloudflare or NGINX. So the question is how can I fix automatically redirecting HTTPS as I want to use HTTP for now. Maybe there are some people with this same problem in the community. Thanks!
Here there are some captures about my not working domain raventechnology.es IP address hidden for privacy and attacks.
The Nginx configuration file for the site:
...ANSWER
Answered 2022-Jan-11 at 08:51For the domain above, it looks like at some point HSTS was enabled. This means that your site was pre-loaded in a browser list, telling the browser that it must be loaded over HTTPS. This means that the site must be served over HTTPS
until after the expiration time of the HSTS policy.
QUESTION
I have one entity with which works 1 separeted thread, every 10 seconds. How it looked before:
...ANSWER
Answered 2021-Dec-31 at 17:04You should change the field from Integer to AtomicInteger.
Even if you use ConcurrentHashMap
you'll see inconsistent results. try running the below code multiple times and see the result.
QUESTION
I'm trying to understand a bit better how async asio works.
I have the following code, where I'm calling async_read on a socket to read the next 10 bytes of data.
...ANSWER
Answered 2021-Dec-15 at 00:14Note: you do not need an extra io_context.
If you have to do long running computation you can write your own async_xyz function and use it like the other async functions. The idea is to post the work to a boost thread pool to do the computation there and then call the completion handler when the work is done. Here is an example using a boost thread pool to do the time consuming hashing of a password.
QUESTION
I have a Django app and in one of its views I use asyncio in order to make some concurent requests to an external component.
Here is the idea:
...ANSWER
Answered 2021-Dec-10 at 14:57According to the documentation, this happens because there is no event loop running at the time when you call gather
.
Deprecated since version 3.10: Deprecation warning is emitted if no positional arguments are provided or not all positional arguments are Future-like objects and there is no running event loop.
As you've probably noticed, your code works. It will continue to work and you can ignore the deprecation warning as long as you use 3.10. At some point in the future, though, this may change to a runtime error.
If you'll bear with me a moment, the recommended way to run an event loop is with run
, not loop.run_until_complete
.
