🚨 Breaking: Downdetector is down... so who's detecting the detector? 🤔

Spotted this gem today and had to share

In need of another downdetector for this downdetector"😂👏

My First Smart Contract! 🚀

I just deployed a SimpleStorage contract on Ethereum Sepolia testnet!

here is the code

// SPDX-License-Identifier: MIT

pragma solidity ^0.8.18;

contract simplestorage {
    uint256 myfavioritenumber;

    struct Person {
        uint256 favioritenumber;
        string name;
    }

    Person[] public listofpeople;

    mapping(string => uint256) public namepointnumber;

    function store(uint256 _favioritenumber) public {
        myfavioritenumber = _favioritenumber;
    }

       function retrieve () public view returns(uint256) {
        return myfavioritenumber;
    }

      function addperson(string memory _name, uint _favioritenumber) public {
        listofpeople.push(Person(_favioritenumber, _name));
        namepointnumber[_name] = _favioritenumber;
    }

      
}

What it does:
✅ Store a favorite number
✅ Retrieve the stored number
✅ Add people with their favorite numbers
✅ Look up people's favorite numbers by name

Functions:
1. store(number) - Save a number
2. retrieve()- Get the stored number
3. addperson(name, number) - Add a person
4. namepointnumber(name) - Look up by name

Tech Stack:
- Solidity ^0.8.18
- Deployed on Sepolia Testnet
- Using Remix IDE

Try it yourself! #Solidity #Blockchain #Web3

The Story of Quiet Building

"The Email that started a Kernel"

In 1991, a 21 year old Finnish student named Linus Torvalds sent a simple message to a newsgroup. He described his hobby: creating a free operating system. He called it "just a hobby, won't be big and professional." That humble kernel, shared openly, became Linux. It wasn't launched with a manifesto, but with a quiet, curious build. It reminds us that foundational things often begin not with a roar, but with a sincere note to a small community.

EVER FELT LIKE managing Python packages and virtual environments was needlessly complex?
Meet

 uv sync --frozen

A single command that replaces:

pip install

virtualenv activation

requirements.txt 

management
What it does:
✨ Installs dependencies in seconds
✨ Creates reproducible environments automatically
✨ Works across projects without conflicts

Why it matters:
Instead of juggling tools, you get one clean workflow. More time building, less time configuring.
From the creators of Ruff, this is the pip/venv workflow killer we've been waiting for.
Your new one-line workflow:

cd your-project uv sync --frozen

Dependencies handled. Environment ready. Ship faster.

"React2Shell" የተሰኘ አደገኛ የዌብ መተግበሪያ የደህንነት ተጋላጭነት መከሰቱ ተገለጸ

"React2Shell" (CVE-2025-55182) የተሰኘው አደገኛ የዌብ መተግበሪያ የደህንነት ተጋላጭነት በዓለም አቀፍ ደረጃ በስፋት ጥቅም ላይ በሚውሉት React እና Next.js በተሰኙ የዌብ አፕሊኬሽን ወሳኝ መዋቅሮች ላይ እጅግ አደገኛ የሆነ የጥቃት ተጋላጭነት መከሰቱ ተገልጿል፡፡

ይህ ተጋላጭነት የመረጃ ጠላፊዎች የተቋማትን ሰርቨር ከርቀት ሆነው ሙሉ በሙሉ እንዲቆጣጠሩ የሚያስችል (Remote Code Execution - RCE) ክፍተትን የፈጠረ ነው። በዚህም የድርጅቶች ጥብቅ መረጃዎች ላልተገባው አካል ወይም የመረጃ መዝባሪዎች እጅ እንዲወድቅ ያደርገዋል፡፡

አሁን ላይ ይህ የጥቃት ተጋላጭነት ክፍተት እንደ አማዞን የዌብ አገልግሎት ደህንነት እና ሌሎችም የስጋት መከታተያ ተቋማት ይፋ እንዳደረጉት መረጃ፤ ተጋላጭነቱ ከተገኘበት እለት አንስቶ ከፍተኛ ፍተሻ እየተደረገ ይገኛል ተብሏል፡፡

በዚህ ክፍተት የሚከተሉት የሶፍትዌር ስሪቶች (Versions) ለጥቃት ተጋላጭ መሆናቸው ተገልጿል፡-

● React: Versions 19.0.0 እስከ 19.0.1 (Experimental releases ጨምሮ)
● Next.js: Versions 13, 14, እና 15 (App Router የሚጠቀሙ ከሆነ)
● React Server Components (RSC) የሚጠቀም ማንኛውም ዌብ አፕሊኬሽን

The Smart API Client ⚡️

Tired of slow API calls and redundant requests? Here's your secret weapon — a caching, timeout-protected fetch function that cuts response times by 80%.

this line of code gonna fetches data once, catches it, times out slow calls, and makes your app feel lightning fast⚡️.

const cache = new Map();

async function smartFetch(url, timeout = 10000) {
    if (cache.has(url)) return cache.get(url);
    
    const controller = new AbortController();
    const timer = setTimeout(() => controller.abort(), timeout);
    
    try {
        const res = await fetch(url, { signal: controller.signal });
        const data = await res.json();
        cache.set(url, data);
        return data;
    } finally {
        clearTimeout(timer);
    }
}

🚀 NestJS vs Express: The Real Difference

Express (Flexibility):

//app.js
const express = require('express');
const app = express();

app.get('/users', (req, res) => {
    // Some logics here
    res.json({ users: [] });
});

NestJS (Architecture):

// user.controller.ts - Built-in structure
import { Controller, Get, UseGuards } from '@nestjs/common';
import { AuthGuard } from './auth.guard';

@Controller('users')
@UseGuards(AuthGuard) // Built-in decorators
export class UsersController {
    @Get()
    getUsers() {
        return { users: [] };
    }
}

🔑 The Key Difference:

Express = You build the house (total freedom) 🏗

NestJS = You get a blueprint + tools (opinionated structure) 📐

🎯 Perfect for:

Express → Quick prototypes, small teams, full control

NestJS → Enterprise apps, large teams, TypeScript lovers
