            Django: Access context data in POST and GET
            Asked 2022-Mar-27 at 08:22

            I am very new to Django and I cannot work out how to access context data within a POST request so I don't have to repeat myself.

            I believe that POST runs before get_context_data, but again unsure of what exactly to do here.

            The page displays some data using a default of 30 days. Then on the page there is a form to override that value, which is passed back to the POST method to then re-render the page.

            Prevent plot generating a line from end to end?
            Asked 2022-Jan-03 at 19:50

            I am trying to plot a set of data with HVPlots that is basically 2 distinct sets of data, which have overlapping but not similar X-axis values. For example, one set of data might have x values that the other set does not. My problem is that one data set will generate a giant line from the lowest available data value to the largest available data value, which is not desirable.

            Is there a way to prevent this giant line from forming? The data comes from a Pandas data frame. Thank you in advance.

            That line coming across is joining two different charts. The data contains 2 "Sensors" which have (technically) overlapping x axis values.

            what you need to do is filter out the data by Sensor, and plot them individually.

            data[data.Sensor.eq('Hyperion')] this will give you data filtered only for the "Hyperion" sensor.

            you can do the same for all unique sensors, and then plot them as individual trances on the same x and y axis to get a multi lined chart.

            SQL Counting Rows based on break values
            Asked 2022-Jan-01 at 12:06

            Frequently I need to do something in SQL Server that I just don't know how to do properly.

            Basically, if I have a table #sample that is like this:

            DEPARTMENT DATE ACCOUNTING A FINANCE A PAYROLL A ACCOUNTING B PAYROLL A FINANCE A PAYROLL B PAYROLL C

            I need to query that table to get an output that is this:

            DEPARTMENT DATE DUPECHECK ACCOUNTING A 1 ACCOUNTING B 2 FINANCE A 1 FINANCE A 1 PAYROLL A 1 PAYROLL A 1 PAYROLL B 2 PAYROLL C 3

            In Oracle Hyperion Brio at my old job I used to create a column that value 1 for every row and writing a function Cume on that column with a break value of the column I needed to count.

            In Excel, I could create a concatenated column that has my break values, and then do a countif(concat:concat,concat1) copy that formula down.

            HypRetrieve not retrieving correct status code
            Asked 2021-Nov-04 at 19:29

            Background

            I have two databases that I need to connect to. One is in Hyperion and the other one is in ESS. I have imported the smartview.bas as stated by the documentation and I am attempting to use the functions within it. I have dummy sheets (SavedLogHyperion and SavedLogESS) for each enviroment to make sure the users logs in before running all the code. I want to retrieve the proper error code if the user closes the window without logging or other things that may prevent the successful login.

            Problem

            The HypRetrieve only acknowledge for the first result: if the user was able to log to Hyperion environment, but if ESS login window is cancelled or provided with non-valid credentials and then closed, it detects the code as 0 ("Ok"), thus detecting a successful login for the second environment when it was not.

            Code

            I wrote a function to retrieve the number, I thought that it could be a time thing and that is why I made it (so for the main code could resolve on time), but it seems like it is not.

            Solution:
            The problem seems to be on how the function works; I noticed that when the function is applied, it activates the sheet, which lead me to believe that there was a problem on timing events, I came with the following solution, which has been basically to provide the scenario that I saw the function is expecting to, also I noticed that if I set the NumCode to retrieve as long as the direct result, it does not behave as expected, my approach was to declare it a variant and then cast it to a long instead.

            How to select R installation when using rpy2 on conda?
            Asked 2021-Sep-19 at 23:49

            tl;dr Can I configure rpy2 so that it loads the conda installation instead of the system one?

            My issue

            When I run rpy2 it uses the system installation of R, but it introspects and loads libraries from my conda installation of R. This has various side effects such as segfaults and so on...

            Reproduction

            I have an installation of R on a Ubuntu 18 server, that my sysadmin has installed. I want to use conda with python and rpy2 to make sure I can select versions somewhat freely.

            Below, you can see I am in a conda environment called (rnvp), that rpy2 identifies the 4.0.5 conda installation of R, but that the rpy2.robjects library loads the system R installation instead, which is 4.0.3.

            Akka.net: Should I specify "split brain resolver" configuration for Lighthouse/Seed nodes
            Asked 2021-Sep-17 at 16:36

            I have this application using Akka.net cluster feature. The people who wrote the code have left the company. I am trying to understand the code and we are planning a deployment.

            The cluster has 2 types of nodes

            QueueServicer: supports sharding and only these nodes should participate in sharding.
            LightHouse: They are just seed nodes, nothing else.

            Lighthouse : 2 nodes
            QueueServicer : 3 Nodes

            I see one of the QueueServicer node unable to join the cluster. Both lighthouse nodes are refusing connection. It constantly tries to join and never succeeds. This has been happening for the last 5 days or so and the node is never dying also. Its CPU and memory usage is high. Also It doesn't have any queue processor actors running when filtered search through the log. It takes long hours for Garbage collection etc. I see in the log for this node, the following.

            {"timestamp":"2021-09-08T22:26:59.025Z", "logger":"Akka.Event.DummyClassForStringSources", "message":Tried to associate with unreachable remote address [akka.tcp://myapp@lighthouse-1:7892].

            There are other "Now supervising", "Stopping" "Started" logs which I am omitting here.

            Can you please verify if the HCON config is correct for split brain resolver and Sharding?

            I think LightHouse/SeeNodes should not have the sharding configuration specified. I think it is a mistake. I also think, split brain resolver configuration might be wrong in LightHouse/SeedNodes and should not be specified for seed nodes.

            I appreciate your help.

            Here is the HOCON for QueueServicer Trimmed

            akka {
                loggers = ["Akka.Logger.log4net.Log4NetLogger, Akka.Logger.log4net"]

            I meant to reply to this sooner.

            Here is your problem: you're using two different split brain resolver configurations - one for the QueueServicer and one for Lighthouse. Therefore, how your cluster resolves itself is going to be quite different depending upon who is the leader of each half of the cluster.

            I would stick with a simple keep-majority strategy and use it uniformly on all nodes throughout the cluster - we're very likely going to enable this by default in Akka.NET v1.5.

            ANSWER

            Answered 2021-Mar-09 at 17:36

            Akka.NET is trying to load hyperion serializer via Type.GetType("Akka.Serialization.HyperionSerializer, Akka.Serialization.Hyperion") call, and fails to do that, because Lighthouse docker image does not include Akka.Serialization.Hyperion package.

            So what you need to do is:

            1. Clone Lighthouse repo and add Akka.Serialization.Hyperion package to Lighthouse project references
            2. Build your own docker image and use it instead.
