Using PowerShell From Windows 8.1 and Windows Server 2012 R2 (Windows PowerShell 4.0) and upwards, you can create a self-signed certificate using the new New-SelfSignedCertificate cmdlet: Examples: New-SelfSignedCertificate -DnsName www.mydomain.example -CertStoreLocation cert:\LocalMachine\My New-SelfSignedCertificate -DnsName subdomain.mydomain.example -CertStoreLocation cert:\LocalMachine\My New-SelfSignedCertificate -DnsName *.mydomain.example -CertStoreLocation cert:\LocalMachine\My Using the IIS Manager Note that IIS certificates use SHA-1 hashing, which isn’t … Read more
Most likely, you have model which contains the same property twice. Perhaps you are using new to hide the base property. Solution is to override the property or use another name. If you share your model, we would be able to elaborate more.
Your models do not have primary keys. But they are being created automatically by django. You need to choose the type of auto-created primary keys: https://docs.djangoproject.com/en/3.2/releases/3.2/#customizing-type-of-auto-created-primary-keys (new in Django 3.2) Either add this to settings.py: DEFAULT_AUTO_FIELD=’django.db.models.AutoField’ or class Topic(models.Model): id = models.AutoField(primary_key=True) …

The first commonly used definition of “memory leak” is, “Memory was allocated and was not subsequently freed before the program terminated.” However, many programmers (rightly) argue that certain … Read more
I usually test the result of docker images -q (as in this script): if [ -z “$(docker images -q myimage:mytag 2> /dev/null)” ]; then # do something fi On Powershell (comment from Garret Wilson): if (!(docker images -q myimage:mytag 2> $null)) { # do something } But since docker images only takes REPOSITORY as parameter, … Read more
If you want to run code on many platforms, go for Posix Threads. They are available almost everywhere and are quite mature. On the other hand if you only use Linux/gcc std::thread is perfectly fine – it has a higher abstraction level, a really good interface and plays nicely with other C++11 classes. The C++11 … Read more
