I accessed WhatsApp Web on a computer with a virus

"The following happens: I downloaded WhatsApp on my phone, which had a backup linked to my email. I accessed WhatsApp Web on a computer with a virus, logged out from there, reset my phone to factory settings, reinstalled WhatsApp, but it no longer had the backup. Then, I accessed WhatsApp Web again. Is there a risk that some virus could once again access the information that was in my backup?"

It's also possible that when accessing WhatsApp Web on the computer with the virus using the backup, the virus may have collected information even though I later logged out. I approximately opened WhatsApp Web for 20 minutes

my soft body object is phasing through collision object

enter image description here

I am following a tutorial, and followed the exact instructions. I baked the simulation (laggy pc) and it looks like this (the outline is the soft body):

Extra details: i have tried both thickening the collision object and increasing the geometry Version: 4.0.2

Geometry nodes, align instances on a face

I tried different ways to place corners instances on a wall model, but I can't figure how to do it so that the alignment would be automatic.

Here I post a simplified example of the problem. There is no solution proposed on this setup. (The blue/red color is the normal direction) enter image description here

Importing MakeHuman assets into Blender

I created a character (human model) in MakeHuman and would like to import it into Blender, make some additional modifications to it, and then save it as a blend (.blend file).

I would think that a super popular open source character editor like MakeHuman would make it really easy to accomplish this. But they don't have any documentation on their site for how to do this, and after searching online all I could find was this YouTube video which makes the process seem super complicated, unsupported and failure prone:

  1. Download an old (2014) plugin for MakeHuman and install it (its no longer supported and may very well not work with modern versions of Blender)
  2. Download BlenderTools from MakeHuman and install them in Blender's scripts/ directory
  3. Restart Blender, then activate the MakeHuman Add-Ons from inside Blender

This seems really brittle and wonky to me. Has anybody ever got this working before? Is there a better/easier way to import MakeHuman assets into Blender?

The Never-Ending IFs


Note: the answer can come in either VB.NET or C#. I have no preference for this Q&A.


I'd like to tame the monstrosity I've created below.

The requirement is to obtain some input from the user and then use that information to generate a Let's Encrypt TLS certificate to be used by the application (a .NET 8 Blazor WebApp in this case).

The whole process consists of the nine steps we see here, with each new step relying on the success of the one just prior. If any one of them fails, we exit the function at that point.

The problem is this has resulted in a maintenance headache with all the cascading If blocks. To complicate matters, some of the steps require as input some of the output generated two or three steps back.

Is there some sort of design pattern or established technique that I can use to manage all of this a bit more cleanly? Surely there must be a better way.

Fully integrated H-bridge motor driver IC VS external FETs

  • Manny

I'm designing a new motor driver for a DC motor which has starting peak current of 30A and 28Volts power supply. Previous engineer used an integrated motor driver IC solution (VNH3SP30-E) that has a MOSFET (Full H-bridge) inside an IC. There are so many customer complaints that it is blowing up in the field. When I look at the IC there is not good separation and everything things runs off the high power line. I don't know what is the advantage of using a integrated driver solution over original MOSFET/IGBT approach. I personally think having external FETs would be a safer approach. Has any one used the integrated solutions before ? if yes, is it better than original power electronics. I'm trying to see which is a better approach.

Atualização automática do código-fonte no ambiente de desenvolvimento Docker, Vue.js e Nginx

Estou enfrentando dificuldades em configurar um ambiente de desenvolvimento com Docker, Vue.js e Nginx, onde as alterações no código-fonte não são atualizadas automaticamente no contêiner Docker em execução.

Aqui está o meu Dockerfile atual:

Code: 
FROM node:lts-alpine as build-stage
WORKDIR /app
COPY package*.json ./
RUN npm install
COPY . .
RUN npm run build

FROM nginx:stable-alpine as production-stage
COPY --from=build-stage /app/dist /usr/share/nginx/html
EXPOSE 80
CMD ["nginx", "-g", "daemon off;"]

Entendo que o container apenas clona o código então tentei resolver esse problema usando o argumento -v no comando docker run, mas sem sucesso, não consegui fazer funcionar corretamente.

Agradeceria muito qualquer orientação ou sugestão para resolver esse problema.

How can I calculate the distance between these instances (circles) and then control the scale based on that distance ?
