Welcome to Software Development on Codidact!
Will you help us build our independent community of developers helping developers? We're small and trying to grow. We welcome questions about all aspects of software development, from design to code to QA and more. Got questions? Got answers? Got code you'd like someone to review? Please join us.

It looks like the answer is "you don't", unfortunately. Because of how our search system works, the "+" character is always treated as an operator. Not that it matters, because non-word characters ...
It is useful sometimes, for example consider a program accepting input in the form of templates. An input of "Value: {obj.field}" is more readable than "Value: {obj['field']}". Such an examp...
You're getting close, just need a few adjustments. Instead of using the hostname property, I prefer to use host, because it also includes the port (in case the URL has one) - check the documentati...
Is -isystem/path/to/sys/includes a standard compiler option, or is it a compiler extension implemented by gcc, clang, and maybe other compilers? Can I rely on its availability? I couldn't find th...
I was trying to initialize a simple two dimensional array as follows: const arrays = Array(3).fill([]); However, when I tried to push an entry into one of the arrays, it seems like it gets push...
Below is a new version of popen2() that works. Some pipe ends were not closed in the linked to original version. (see the branch for "pid != 0", where extra handles are closed - whether there is ...
Angular 12; .NET Core 3.1 Following a code-maze tutorial, I have a working authentication (registration/login) service using .NET Core Identity. After login, I would like to add 'username' data ...
There are quite a few bugs there :-) Let's start with with the big one: In Angular (and most client side web frameworks) requests to the server happen asynchronously. That is, when a method does ...
docutils's rst2pseudoxml.py is reporting this error: Unknown interpreted text role "meth". even though the build command: sphinx-build -b html -d build/doctrees source build/html runs fine and pro...
Despite the fact that I have programmed against SQL Server for quite a while I did not pay much attention to the tempdb database. This is especially true if application logic is mostly written usin...
We use Kubernetes on a cloud (GKE, to be precise). We use RabbitMQ for messaging and we need to upgrade it from 3.10 to 3.12 . FWIW RabbitMQ has been added to our system using a chart from Bitnami...
For another perspective, I use TortoiseGit (https://tortoisegit.org/) on Windows a fair bit: Checkout the branch. Open the log window (Git Show log). Right-click on the commit/branch...
More specifically: Is there a dedicated docs page listing "properties" that are idiosyncratic to F# .fsproj project files? Why am I asking? Started learning F# a couple of days ago, but just now ...
I would need to check, but I don't think PostgreSQL or most (any?) relational databases have a good way of expressing this "at most 8" constraint. It may be possible to express it in some way but p...
strcpy(3) can be safe. Some compilers, such as GCC and Clang, use a feature test macro, _FORTIFY_SOURCE, (see feature_test_macros(7) https://man7.org/linux/man-pages/man7/feature_test_macros.7.htm...
The reverse proxy is frankly a "best practice" architecture, not just for security but also for resource limiting of your hard-working application server. Often the reverse proxy will communicate ...
Add the following to /etc/containers/registries.conf: unqualified-search-registries = ["docker.io"] [[registry]] location = "docker.io" Now you can pull just like you would in docker: podm...
Unlike docker, Podman won't (understandably) use docker hub by default. You can use it explicitly like this: (just using a random example here, it's an OpenAPI linter) podman pull docker.io/dshanl...
When writing a dynamic web service, you broadly speaking have two paths: Use an existing web server (e.g. Apache, Nginx or Lighttpd) to handle the "raw" web requests and implement your own cod...
First, a reminder to future self (the figure RFC 3986, Section 3. Syntax Components complemented with Section 3.2. Authority): The following are two example URIs and their component parts: ...
Generallly (assuming no exploit is found) it's not possible to escalate the privileges of an already running process, except via code that itself has kernel level access (running in ring 0 - this i...
When you try to do a privileged systemd operation without the privilege, you get an escalation prompt: $ systemctl stop docker ==== AUTHENTICATING FOR org.freedesktop.systemd1.manage-units ==== ...
Specification You understand correctly. Matrix is an interface for federated encrypted communication. From the first page of the spec: Matrix defines a set of open APIs for decentralised commun...
Ok I got it working again. The issue was that I had updated my kubeconfig file, and the current-context setting had changed. This setting essentially selects which cluster kubectl targets. Now th...
The annotation processor must be compiled before it can be used. This is not a problem if you're using it as a dependency from Maven Central, for example. If you want to use a custom processor, you...
