I have a Python 3.6 data processing task that involves pre-loading a large dict for looking up dates by ID for use in a subsequent step by a pool of sub-processes managed by the multiprocessing module. This process was eating up most if not all of the memory on the box, so one optimisation I applied was to 'intern' the string dates being stored in the dict. This reduced the memory footprint of the dict by several GBs as I expected it would, but it also had another unexpected effect.

Before applying interning, the sub-processes would gradually eat more and more memory as they executed, which I believe was down to them having to copy the dict gradually from global memory across to the sub-processes' individual allocated memory (this is running on Linux and so benefits from the copy-on-write behaviour of fork()). Even though I'm not updating the dict in the sub-processes, it looks like read-only access can still trigger copy-on-write through reference counting.

I was only expecting the interning to reduce the memory footprint of the dict, but in fact it stopped the memory usage gradually increasing over the sub-processes lifetime as well.

Here's a minimal example I was able to build that replicates the behaviour, although it requires a large file to load in and populate the dict with and a sufficient amount of repetition in the values to make sure that interning provides a benefit.

Apparently, in the move from Spring Boot 1 to Spring Boot 2 (Spring 5), the encoding behavior of URL parameters for RestTemplates changed. It seems unusually difficult to get a general query parameter on rest templates passed so that characters that have special meanings such as "+" get properly escaped. It seems that, since "+" is a valid character, it doesn't get escaped, even though its meaning gets altered (see here). This seems bizarre, counter-intuitive, and against every other convention on every other platform. More importantly, I can't figure out how to easily get around it. If I encode the string first, it gets double-encoded, because the "%"s get re-encoded. Anyway, this seems like it should be something very simple that the framework does, but I'm not figuring it out.

Here is my code that worked in Spring Boot 1:

This is for a class assignment, but I can't figure out how to fix my problem. I wrote the following:

I tried to write a simple Prolog program with the following ruleset.

I am trying to build Qt3D as it seems to not ship by default with Qt6 anymore.

I just finished installation on ubuntu, without major issue (it would have helped if the install instruction could have mentioned that the vulkan sdk is required, which was not obvious, but after installing the SDK the compilation finished successfully). I used the Qt Creator to build the library.

I am trying to do the same on windows, I installed both perl and vulkan as per install instructions above. After opening the qt3d.pro project and attempting to build it in Release mode, I am getting stuck where vulkan is requires

I recently started playing with Arduinos, and, coming from the Java world, I am struggling to contend with the constraints of microcontroller programming. I am slipping ever closer to the Arduino 2-kilobyte RAM limit.

A puzzle I face constantly is how to make code more reusable and reconfigurable, without increasing its compiled size, especially when it is used in only one particular configuration in a particular build.

For example, a generic driver class for 7-segment number displays will need, at minimum, configuration for the I/O pin number for each LED segment, to make the class usable with different circuits:
