How to pass any coding interview in 3 simple steps (without grinding 691 problems):

[Santiago @svpino]

Google published an entire library of highly sophisticated, end-to-end agent examples.

100% open-source.

• Complete documentation
• Source code
• Ability to one-click deploy

In the video, I break down one of the coolest examples in this collection.

Rolling your own authentication is almost never worth it.

At first, it looks simple:

- store users
- hash passwords
- issue tokens
- validate tokens

Then the real requirements show up:

- password resets
- email verification
- MFA
- refresh tokens
- session management
- social login
- enterprise SSO
- security patches forever

This is why I like using Keycloak.

It gives you a full identity provider you can run in a container.

Your ASPNET Core API does not handle user credentials.

It only validates signed JWTs.

The flow looks like this:

1. User clicks Authorize in your UI
2. Browser redirects to Keycloak
3. User logs in there
4. Keycloak redirects back with an authorization code
5. Your UI exchanges it for tokens using PKCE
6. API receives the Bearer token
7. ASPNET Core validates the token signature, issuer, audience, and claims

The important part:

Your API does not call Keycloak on every request.

It fetches the signing keys from the JWKS endpoint, caches them, and validates tokens locally.

Fast, clean, and much easier to reason about.

For local development, you can spin up Keycloak with Docker, create a realm, register a public client, wire Swagger UI to OAuth 2.0, and add JWT Bearer authentication in ASPNET Core.

For production, don’t forget the boring but important parts:

- HTTPS everywhere
- persistent storage
- proper hostname configuration
- no relaxed metadata validation

I wrote a full walkthrough of integrating Keycloak with ASPNET Core using OAuth 2.0, Authorization Code + PKCE, Swagger UI, JWT validation, and Aspire tracing: https://t.co/z2iS1RB6ty

R.I.P Dropbox, iCloud, and OneDrive subscriptions.

Someone open-sourced a sync tool that replaces all three for $0. And no company can shut it down.

It's called Syncthing.

Here's how it works:

Every cloud storage company on earth routes your files through their own servers. That's not a technical requirement. That's a business model.

Syncthing skips the server entirely.

→ Your devices connect directly to each other
→ Every transfer is TLS encrypted with perfect forward secrecy
→ Every device is authenticated by a cryptographic certificate
→ Nothing moves without your explicit permission
→ Works on Windows, macOS, Linux, Android, FreeBSD

No account. No subscription. No company holding a copy of your files.

Dropbox can raise prices. iCloud can change its terms. Google Drive can shut down tomorrow.

Syncthing runs on your own machines. There's no server to breach. No company to pressure. No subscription to cancel.

One install. Your devices. Your files. Your rules.

100% Opensource.

Windows 11 has been secretly running a keylogger in the background

this whole time

and sending every keystroke to Microsoft servers.
Here's the fix they don't want you to know about

Win+R → regedit → HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Input\TIPC → Double click "Enabled" → Set value to 0 → Restart PC

Stop Microsoft from reading every word you type in Valorant chat, Discord, and Chrome.

Say goodbye to Google Workspace.

Someone built a complete replacement that runs on your own server, costs nothing, and has 400+ apps.

It's called Nextcloud. 400,000 organizations are already running it. The German federal government switched to it. The French public sector switched to it. The European Parliament uses it.

None of them are doing it to save money.

Here's what one install actually gives you:

→ File sync and sharing that works exactly like Dropbox
→ Live document editing with full Word/Excel compatibility, no internet required
→ Video calls with end-to-end encryption and no vendor in the call with you
→ Photo backup with local AI face grouping, your machine, your data
→ Calendar and contacts synced to every device through open standards
→ 400+ apps including Jira-style project boards, Spotify-style music streaming, and RSS readers

The architecture is the part nobody talks about.

Nextcloud does not route your data through their servers. Ever. Your server talks directly to your devices. No company in the middle. No terms of service that can change overnight. No price increase email you have to swallow.

Google Workspace costs $12/user/month and owns everything you put in it.

Nextcloud costs whatever your VPS costs and owns nothing.

35K stars. 100% Opensource.

Earlier today Cloudflare's CSO shared how they tested Anthropic Mythos using an unreleased 8-stage vulnerability-discovery agent. So I asked Opus to implement the agent for me, it works via Claude SDK with a Pro or Max subscription, no API.

`agent-memory` by @neo4j is the best open-source repository for building a unified memory layer for AI agents via knowledge graphs.

They did such an amazing job modeling short, long, and reasoning memory, their ontology, and extraction algorithms.

After spending 2 days dissecting and testing their code, I wrote a full piece on https://t.co/NYVGH6MvYd explaining how it works. I will publish it tomorrow.

The Psychology Of Achievement: 9 Essential Mindsets That Define World-Class Success📍

[Milena Wood @Milena_Coder]

The best strategic thinking👇

[Seerat Fatima @SeeratFatima112]

I tested 8 AI ghostwriting tools so you don’t waste your money.

And one thing became painfully obvious:

Most AI tools can write.

Very few can write like YOU.

That’s the real game now.

I compared them on:

• Pricing
• Speed
• Voice replication
• Context awareness
• Memory
• Workflow experience

Here’s what stood out 👇

🏆 Stanley 27/30
Probably the closest thing to an AI clone of your writing style.

🥈 Claude Opus 4.7 26/30
Insanely good for deep writing and long-form content.

🥉 GPT-5.5 24/30
The best all-rounder for creators, marketers, and personal brands.

Then came:
• Gemini 3.1 Pro 22/30
• Copilot 22/30
• Grok 4 21/30
• DeepSeek V4 20/30
• Perplexity AI 16/30

The future of AI content isn’t about better writing.
It’s about better memory.

The tools winning right now are the ones that:

→ learn your tone
→ remember your context
→ adapt to your workflow
→ sound human consistently

Soon, everyone will have access to AI.

But not everyone will have AI trained on THEIR brain.
That will be the real advantage.

Which AI tool do you think writes most like a human right now?

BREAKING: According to our analysis, ~$920 million worth of crude oil shorts were taken 70 minutes before an Axios report claimed the US and Iran were near a "14-point" deal to end the war.

At 3:40 AM ET today, nearly 10,000 contracts worth of crude oil shorts were taken without any major news.

This is equivalent to ~$920 million in notional value, an unusually large trade for 3:40 AM ET.

At 4:50 AM ET, just 70 minutes later, Axios reported that the US is "close" to a "memorandum of understanding" to end the Iran War.

By 7:00 AM ET, oil prices had fallen over -12% with these crude oil shorts gaining approximately +$125 million.

Minutes later, Iran launched the "Persian Gulf Strait Authority" and oil prices surged +8%.

What just happened?
