Hello everyone, I hope you're having a good day. 

I’ve been trying to understand the security of a website I’ve been working on for the past few weeks. However, I don’t have much knowledge about cybersecurity. I need your help and insights. 

Here’s the setup: the frontend of my project runs on Next.js (App Router, TypeScript, TailwindCSS) and Cloudflare Workers. 

The backend uses Django (Python), Wagtail CMS, and a PostgreSQL database. I’m running this on my own VPS server as a Docker container. There’s also a reverse proxy web server called Caddy. I haven’t made the website public yet. I currently only have two URLs: dev.xx.com and api-dev.xx.com. Of course, once I’ve addressed all my concerns regarding security vulnerabilities, I’ll change it to www.xx.com, but as I mentioned at the beginning… Can I use a Deepseek V4 Pro-enabled Hermes agent to report any vulnerabilities it detects without causing harm to my project? This method might seem silly to you, but as I said, since I don’t know much about cybersecurity, this solution came to mind. Does anyone have other suggestions? I’m especially curious about your recommendations regarding agent-based coding. I’d like to thank everyone in advance for their responses. Best regards.

Herkese sağlıklı günler dilerim. Benim sporsuz herhangi bir günüm yok. Her gün mutlaka ya arkadaşımla boks yapmaya çıkarım ya da fitness'a giderim. 110 kilo olmama rağmen 187 boyunda, kalıplıyım ve fazla göbeğim çıkmıyor. Ama tatlı yemeyi durduramadığım için kilom her defasında artıyor. Bunu engellemenin bir yolu yok mu ? Demek istediğim tatlı yemeyi engellemenin bir yolu yok mu ?

I’m building a paper-trading / decision-support system for silver, and I’d like a sanity check from people who have built trading or market-data systems before.

Important context: this is not a real-money trading bot. It does not connect to bank accounts, does not automate bank actions, and does not execute live trades. The goal is to simulate what would happen with a virtual balance and evaluate whether my architecture makes sense.

Current architecture:

• FastAPI backend
• PostgreSQL
• Docker Compose on a VPS
• CI/CD with GitHub Actions and manual VPS smoke tests
• paper-trading engine with a virtual starting balance
• deterministic risk engine
• collectors for:
  • bank silver buy/sell prices
  • global XAG/USD
  • USD/TRY
  • Fed RSS
  • FRED macro series
• collector health / freshness / duplicate checks
• validation gate before allowing risk-policy progression

Important decisions I made:

• backend policy owns decisions
• LLM agents will only explain, critique, summarize, or report
• no real trading path
• no bank login or bank automation
• no paid market-data APIs for MVP
• raw data is append-only
• missing or stale execution-critical data blocks paper trades
• context data like Fed/FRED can degrade analysis but should not block everything by itself

Execution-critical sources:

• bank silver buy/sell price
• global XAG/USD
• USD/TRY

Context sources:

• Fed RSS
• FRED macro data
• later maybe TCMB EVDS / TÜİK / BLS direct

Current question:

Does this architecture sound reasonable for a serious paper-trading simulation, or am I missing something fundamental?

I’m especially looking for criticism on:

1. separating execution-critical data from context data
2. blocking trades on stale/missing critical data
3. using deterministic rules before ML
4. delaying ML until enough clean data exists
5. whether my validation gate is too strict or not strict enough
6. whether buy-and-hold comparison should be mandatory before claiming any strategy works
7. what risk metrics I should add before moving to backtesting

I’m not asking for trading signals or financial advice. I’m looking for architectural and risk-modeling feedback.

Hi everyone,

I’m a computer engineer working at a company where I’m also responsible for a large part of the social media content production. The problem is that I’m not a designer or video editor, and I don’t really have enough time or creative background to consistently produce polished, modern, corporate-looking content.

Right now, I need to create two main types of content:

Visual posts / posters / announcements

These usually include event or campaign information, dates, prices, contact details, and some promotional text. I can find photos for these designs, but I would prefer not to rely too much on obvious AI-generated “AI slop” images. I want the designs to look professional and trustworthy, not cheap or generic.

Short videos / reels / social media clips

I have a lot of high-quality videos available, plus many videos sent by customers. I want to turn these into clean, modern, engaging short-form videos. Sometimes these videos are for promotion, sometimes they are just for engagement. Ideally, I want something that can help me pick useful clips, combine them, add transitions, music, text, subtitles, and make the final result look good without spending hours manually editing.

Here’s what I already have:

Canva Pro

CapCut Pro

A lot of high-quality video material

Customer-submitted videos

Access to photos for posters and announcements

I know Canva Sheets and Google Sheets exist

I’m comfortable with technical tools, APIs, scripts, automation platforms, etc.

I’m aware of tools like n8n, Make, Zapier, and similar automation platforms

What I’m trying to figure out is the most practical workflow.

I don’t necessarily need a fully autonomous AI system that creates everything from scratch. In fact, I’d rather use my existing media assets and let AI/automation help with structure, editing, layout suggestions, resizing, captions, repetitive design work, and content organization.

My questions are:

Can Canva Pro and CapCut Pro realistically be enough for this if I build the right workflow?

Is there a way to use Canva templates + Google Sheets / Canva Sheets to semi-automate announcement posters without needing Canva Enterprise API access?

Are there any good automation workflows with n8n, Make, or other tools for this kind of social media production?

Are there any open-source GitHub projects that help automate poster generation, video editing, CapCut drafts, or social media content pipelines?

What would be a realistic workflow for someone technical but not design-oriented?

Should I focus on building a template library first, then automate around it?

For videos, should I stay inside CapCut/Canva, or use another AI clipping/editing tool before final polishing?

My goal is not to spam low-quality AI content. I want a repeatable system that helps me produce professional-looking social media posts and videos faster, while still keeping human review and brand consistency.

I’d really appreciate any advice, tool recommendations, workflow examples, GitHub repos, or practical experiences from people who have solved a similar problem.

Thanks in advance.

Merhabalar. Next.js ile yazılan frontend tarafını cloudflare ile ayağa kaldırmaya başladığım sitenin django ile yazılmış backend'ini deploy etmek için bir VPS arayışındayım. Hosting dünyam çok cazip geliyor bana ama emin de olamıyorum. Çünkü şikayetvar ve ekşisözlükte çok olumsuz şeyler söylemişler. Çok fazla değil minimum 4 CPU 6 GB RAM benim için yeterli olacaktır. Ama yabancı VPS'lere baktığımda USD-EUR bazlı fiyat verdikleri için çok pahalı oluyor müdür de kabul etmiyor. Hosting dünyama ise makul gözle bakıyor. Bu aşamada ne tavsiye edersiniz ? Hosting dünyama güvenmeli miyim ? Yoksa önerebileceğiniz başka VPS'ler var mı ?
