I have to modify a legacy Django web application where there are 2 tables to store the same information using the same database structure, and the only difference is the names of the tables (and th...
As far as I can tell, it is in part determined by the HTML spec's History API1, specifically the value of history.scrollRestoration. Quoting the HTML spec's scroll restoration mode paragraph: ...
I have a project I normally build with nix and cabal, however I also want to publish my documentation onto gitlab pages. It's impractical to run my nix on the gitlab CI, so I've just been using cab...
Suppose I have an Azure Synapse Serverless SQL database. I can run the following to get the sid of added groups: select name, type_desc, authentication_type_desc, sid from sys.database_principal...
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 ==== ...
#3: I still don't know what exactly is going on, but experimenting today, I found a workaround at least: align-items: normal; on the container and object-fit: scale-down; on the image. Due to the...
Elaborating with an example: Java doesn't allow imports to aliased (not currently), to my knowledge. The current standard is writing out the fully-qualified name: ClassA.java: package com.fol...
I browse deviantArt from time to time and I wanted to make images display bigger, because there is so much useless whitespace on that site. On first glance that would be simple - remove the set di...
In Eclipse, is it possible to setup custom errors or markers in the editor, for annotation processing? For example, the standard squiggly lines with descriptions. This question is not important. ...
I'm trying to build a proper understanding of what an OLAP[1] datastore vs an OLAP data engine is. I tend to put too much value on keywords like "engine" vs "data store." If it has "engine," I thin...
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...
Since Matrix messenger offers only a protocol,[1] as a software engineer I can choose to: Write my own client or use an existing client Write my own server with my own server logic or join an e...
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...
I'm getting an error when trying to open a shell to a pod. This used to work. $ kubectl exec --tty --stdin --namespace my-ns my-pod -- sh Error from server (BadRequest): Upgrade request required ...
I'm trying to write a bash function that can sanitize filenames to make them compatible with both Linux and Windows file systems. The function should perform the following operations: Replace in...
Some web sites are able to detect that Developer Tools is open as output a message in a the console. How does JavaScript know that the Chrome DevTools are open? Could this be spoofed?
When I open VS Code inside a project dir, it reopens all the tabs that were open last time, and re-expands all the folders that were unfolded last time. I find this annoying. Usually, when I close...
The problem with undefined behavior due to array out of bounds happens whenever we use pointer arithmetic, which is only defined to work within the bounds of an array. Where plain variables, "scala...
The simplest solution I managed to find is robusta. It still has a bunch of unnecessary features, but with the correct configuration it's possible to disable these. As a bonus, it nicely adds some...
They are not a part of git the way .gitignore files are. It's just a convention to add empty directories to git repositories. Normally git ignores empty directories altogether. Adding an empty fil...
Sometimes there are empty files named .gitkeep sprinkled around a repository. What are these files?
when I look at the type signatures, it is not supposed to work. The types work because they're parameterized. The types of the combinators involved are (renaming all parameters to be unique fo...
C prohibits accessing an array out of bounds even if measures were taken to ensure that what should lie outside those bounds were known: struct MyStruct { int x[2]; int y, z; }; static...
Asked How to implement map using the fish (>=>, Kleisli composition) operator in F#? a couple of hours ago, and r~~'s answer blew my mind: let map f = id >=> switch f It is perfect ...
