QUESTION

R - Removing rows from one table based on unique combination from another table

Asked 2021-Jun-14 at 17:19

I have two tables. Table A - Base table with full data. Table B - Contains grouped data by the combination (Origin- Destination- Carrier- Class). It has only those combinations which have both Premium and Economy class and also greater than 100 passengers each.

My objective is to only include those rows in Table A which pertain to combinations in Table B. Sample tables are below -

Table A

ItinID Origin Destination Carrier Class Fare 1 AB BC Delta Econ 100 2 AB BC Delta Premium 500 3 CD DE American Econ 200 4 EF FG United Econ 200 5 AB BC Delta Econ 150 6 AB BC Delta Premium 700

Table B

Origin Destination Carrier Class AB BC Delta Econ AB BC Delta Premium

The output table that I need is-

ItinID Origin Destination Carrier Class Fare 1 AB BC Delta Econ 100 2 AB BC Delta Premium 500 5 AB BC Delta Econ 150 6 AB BC Delta Premium 700

Also, is there a way to skip making Table B altogether and directly running operation on Table A to get the output table?

Thank you

1) Here are base, dplyr and sqldf solutions. We join A and B and then sort by ItinID (although it seems that the dplyr solution is already sorted that way so we omit that part for it).

How to store an Object-Array in native Memory using Java Panama

Asked 2021-Jun-12 at 13:54

I want to implement a datastructure in native memory using the Foreign Memory Access API of Project Panama.

In order to do that I need an underlying Object array (Object[]) for the entries.

In all the examples for the Foreign Memory Access API, MemorySegments are only used to store and retrieve primitives like so:

...

ANSWER

Answered 2021-Jun-12 at 13:54

Is there a way to store non primitives in a MemorySegment (e.g. Object)?

No, at least not directly. Objects are managed by the Java runtime, and they can not be safely stored in native memory (for instance because the garbage collector would not be able to trace object references inside objects in native memory).

However, as noted in the comments, for your purposes it might be enough to store the data inside an object in native memory. For instance, if an object contains only primitive fields (though, the same could be done recursively for object fields), it would be possible to write each such field separately to native memory. For example (with the JDK 16 API):

QUESTION

JavaScript not waiting for the response from the endpoint

Asked 2021-Jun-12 at 05:59

Background

This is the client side Javascript, where I make a post request to update the respective tables with the form parameters. My database has two tables-Rabbit table, and MyStuff table, and MyStuff table holds a foreign key to the rabbit table. Now, I first update the Rabbit table by making a post request which not only updates the Rabbit table but also updates the value of the rabbitID variable in the server, and the second request updates the MyStuff with the respective form parameters, and also makes use of the rabbitID variable just updated.

con.query() is asynchronous. since it's asynchronous it only awaits till that line and starts executing other endpoints. that's why your code is out of order

QUESTION

Pandas: Reorder values in one column within the groups that are created based on another column

Asked 2021-Jun-11 at 16:53

My data is already sorted by groups based on one column. And within each group I am trying to reorder the values in another column. The below example illustrates what I mean:

Currently my data looks like this, its sorted by the carrier name. The 3rd column shows what type of products they're holding. However, I would like chicken to be first on the list for every carrier, so that it looks like the second table below.

Name Amount Product Carrier A 1 Apples Carrier A 9 Oranges Carrier A 8 Bananas Carrier A 10 Chicken Carrier A 28 Total Carrier B 9 Apples Carrier B 4 Oranges Carrier B 6 Bananas Carrier B 9 Chicken Carrier B 28 Total Carrier C 5 Apples Carrier C 8 Oranges Carrier C 9 Bananas Carrier C 10 Chicken Carrier C 32 Total

The below table is what I am trying to achieve.

Name Amount Product Carrier A 10 Chicken Carrier A 1 Apples Carrier A 9 Oranges Carrier A 8 Bananas Carrier A 18 Total Carrier B 9 Chicken Carrier B 9 Apples Carrier B 4 Oranges Carrier B 6 Bananas Carrier B 19 Total Carrier C 10 Chicken Carrier C 5 Apples Carrier C 8 Oranges Carrier C 9 Bananas Carrier C 22 Total

Is there a way to do this with pandas? Instinctively I looked at feeding df.sort_value both the Name and Product columns, but realized that it can only sort by ascending and descending order.

Also the order of values in the "Name" column must be preserved for my task. In this example, its already ordered alphabetically, but its not necessarily the case nor my intention in my actual dataset.

Any insight would be appreciated!

FirebaseFirestore.getInstance() and app has stoped

I run my Android app (based on Java), and it works. Next, I add to my app code:

App runs, but next the running device shows the message "app has stopped".

I use a device simulator available in Android Studio.

It is my first Android app, and I can't understand what is going.

At the end of your log, just before the initial crash. there is a warning:

Default FirebaseApp failed to initialize because no default options were found. This usually means that com.google.gms:google-services was not applied to your gradle project.

simply adding com.google.gms:google-services should fix any issues you have, if you have issues, ensure your Gradle cache is cleared or run without the build cache --no-build-cache

TTN decoder - Node-red

Asked 2021-Jun-08 at 05:25

In TTN they are no longer supporting large decoders.

I know what the decoder needs to be in TTN, it is in my DECODER function, but dont know how to execute it in the function node.

If you use inject Payload [1,2,3] RAW, it injects the raw payload that is msg.payload.payload.uplink_message.frm_payload into the decoder.

The DECODER needs to decode the raw payload and output it in msg.payload.uplink_message.decoded_payload

If you use inject Payload [1,2,3] Decoded in the flow you see how the end result needs to look like and the decoded msg.payload.uplink_message.decoded_payload

Why my UL lists are displayed horizontal?

Asked 2021-Jun-01 at 04:58

I am trying to make my footer displays 4

display:inline;

ANSWER

Answered 2021-May-31 at 11:02

If you want to make this navigational unordered list horizontal, you have basically two options:

Make the list items inline instead of the default block. .li { display: inline; } This will not force breaks after the list items and they will line up horizontally as far as they are able. Float the list items. Since we very often want our list items to display as blocks so we are able to set fixed widths on them, we are forced to float them to the left or right to line them up horizontally.
