QUESTION
This is the question: Is it possible to look at the outputs, what has been selected, from the previous row of a running SQL query in Postgres?
I know that lag exists to look at the inputs, the "from" of the query. I also know that a CTE, subquery or lateral join can solve most issues of this kind. But I think the problem I'm facing genuinely requires a peek at the output of the previous row. Why? Because the output of the current row depends on a constant from a lookup table and the value used too look up that constant is an aggregate of all the previous rows. And if that lookup returns the wrong constant all subsequent rows will be increasingly off from the expected value.
The whole rest of this text is a simplified example based on the problem I'm facing. It should be possible to input it to PostgreSQL 12 and above and play around. I'm terribly sorry that it is as complicated as it is, but I think it is the most simple I can make it while still retaining the core issue: lookup in lookup table based on an aggregate from all previous rows as well as the fact that the "inventory" that's being tracked is modeled as a series of transactions of two discrete types.
The database itself exists to keep track of multiple fish farms, or cages full of fish. Fish can be moved/transferred from between these farms and the farms are fed about daily. Why not just carry the aggregate as a field in the table? Because it should be possible to switch out the lookup table after the season is over, to adjust it to better match with reality.
...ANSWER
Answered 2022-Feb-08 at 12:53You have to formulate a recursive subquery. I posted a simplified version of this question over at the DBA SE and got the answer there. The answer to that question can be found here and can be expanded to this more complicated question, though I would wager that no one will ever have the interest to do that.

I'm using Doxygen v1.9.2 to document an embedded application written in C. I also use git as versioning tool. I had documented the code for example in v2.0.0 and everything was ok. Recently I made some improvements and added 2 new files and new functionalities in the application. I documented the newly added files as per instruction of doxygen and some stackoverflow topics, but I did not figure out why the new file is partially documented. Since the project is a little large relatively, I will try to illustrate the documentation structure and add only issue related parts to avoid crowd and focus to the issue.
Necessarily sharing he Doxyfile config; comments, blank lines and some directory paths are omitted for brevity:
...ANSWER
Answered 2021-Dec-02 at 19:32Since @albert didn't post an answer to check it as a solution, I needed to post an answer for anyone who struggle with the same problem.
Briefly the solution to this problem that I've faced was not to use nested grouping blocks. Grouping blocks start with @{ and end with @}. This structure currently cannot be used nested in Doxygen v1.9.2.
As Albert pointed out and made me understand, I needed to make each grouping block as an individual block and without nesting. After doing this all documented members finally appeared on the html output page. I share the source code with fixed documentation for anyone who wants to compare the erroneous documentation (see the question) and the fixed working documentation.
QUESTION
This is an exercise in a class I am taking. I posted this to the message board and the feedback I was given stated that I am only working with the last name in a list of names. Ultimately, when this runs, it only returns {Marin:1} whereas it should return a dictionary containing all first names as the key and the value is the number of times the name appears in a list. Any and all help is appreciated.
...ANSWER
Answered 2021-Nov-19 at 17:45You were so close you had all the right ideas, but you're doing too much. You can just keep adding 1 whenever you get a name. It's very simple to do if you use the get method for dictionaries.

Answered 2020-Oct-15 at 07:30As far as I know, the L2Switch feature which was responsible for L2 switching is not supporting after the Fluorine version. There is no module for arp handling l2 switching. It may visible to write a code to do L2 forwarding.
P.S Regarding your topo "This topology has LOOPS and WILL NOT WORK with the default controller or any Ethernet bridge without STP turned on! It can be used with STP, e.g"

QUESTION
TL;DR -> How to integrate a local Opendaylight Karaf App in the Opendaylight integration/distribution project, for local use? I am not looking to publish my code to upstream to official opendaylight repositories.
I am trying to understand how to make changes to source code of certain features in Opendaylight to fulfill my custom use-cases.
For this, I downloaded the Netconf Source code from "https://git.opendaylight.org/gerrit/netconf" and the distribution source code from "https://git.opendaylight.org/gerrit/integration/distribution".
I made certain modifications in the Netconf Code and built it using mvn clean install -Pq -Dcheckstyle.skip.
Now, how do I go about integrating these updates in the integration/distribution project?
FYI:
- I am working on ODL "release/oxygen-sr2". However, I realise that newer versions are available and I am open to shifting to them.
- Using Java 8 and Maven 3.6.0
- I had been suggested that I could just maven build the Netconf Project code and run Apache Karaf from there. Any other feature could then be installed via the Karaf CLI. But, my use case would require modifications on multiple existing features and even creating a new feature. Therefore, this solution also doesn't work for me as I would still need to integrate everything in one central project.
ANSWER
Answered 2020-Sep-07 at 22:49Actually, it's pretty simple, but maybe not obvious. Build all the projects you want locally, then build the integration/distribution project. Any artifacts it finds in the local m2 repo will be used for the final int/dist karaf that will get created.
in other words, for every project you want to customize, pull that repo, make your changes, build it. Then as a last step, build the int/dist project.

I am going mad with doxygen at the moment, i hope it is not too stupid on layer 8, but we will see...
I want to extract static and undocumented stuff. That's why EXTRACT_ALL = YES for now. But EXTRACT_ALL seems to be not working as the documentation intents. See Example below.
Against the documentation of EXTRACT_ALL there are still warnings in the output.

This means that doxygen 1.8.19 cannot be started from doxygen wizard but you have to use the command line to run doxygen.

QUESTION
My team is using OpenDaylight 0.11.0 as the basis for a SDN controller. I am wondering how that .tar.gz is built?
I.e., is there a base project on github and a maven command that creates that .tar.gz file?
I am finding so many different opendaylight related modules, features and code bases that I simply can't find the full source code from which the above noted tar.gz is built from. I am thinking it is a combination of many different opendaylight modules, however I am sure there is a parent project that bundles them all together.
My end goal is to build a custom feature for our team that can be feature:installed in ODL 0.11.0's karaf console.
We have already followed the dev guide here, however that base project doesn't contain many of the features available on the ODL 0.11.0 linked at the top. I.e., when you build out that sample project, it doesn't come with the same set of features as the ODL 0.11.0 tar.gz linked above.
...ANSWER
Answered 2020-Jul-16 at 21:41yes, ODL as a whole is just comprised of a bunch of smaller, more specific, projects. Here is a way to visualize it. So you could just clone one of those projects that does something you want, (e.g., netconf) and build that (mvn clean install). That would build netconf and pull in all the artifacts of everything it depends on. At the end you would get something you could run (netconf/karaf/target/assembly/bin/karaf) and then install some netconf features.
If you want the whole thing, like you'd find by going to the downloads page, then you can clone our integration/distribution repo. That will pull in the artifacts for all of those projects and you could install netvirt and bgpcep features for example. That build would result in the .tar.gz file you are referring to.
So, in the end if you want to create some new project you could build that locally. Then, you would have to update the integration/distribution project to pull in your new project (probably could just follow how it's doing it for other projects), then build it. If all goes well, you'd get the full distribution with all the features including the new one.
Good Luck!

QUESTION
I have the topology that is represented in the image:
I want the hosts 1 and 2 to have high priority with max bandwidth 8mbps and the host(server) 4 to receive packets at maximum bandwidth of 4mbps. Host 3 is irrelevant for now. I have achieved the connections between h1 h2 h4 but when I turn the host 4 in a server as shown it becomes unreachable and I can't make it reachable with everything I tried so far.How can I make it reachable from h1 and h2 after making it a server? The other problem I have faced is that I can't find a way to implement the Qos rules for achieving the wanted bandwidth. Everything is implemented with mininet, ODL remote controller and for the bandwidth checks I use Xterm.
...ANSWER
Answered 2020-Jul-08 at 20:42Since you are in a tree topology, you don't have loop, and I assume that you configured ODL correctly. I don't see the necessity to install most of the rules that you listed.
Before adding any rule try to run the pingall and check that the controller is working correctly (since some ping are received it seems to work)
