how NGINX handles hundreds of thousands of requests per second?
it uses a Master-Worker Model and i’ve implemented the same architecture in my own mini-nginx called NxLite.
here’s how it works:
Master Process:
- loads config
- sets up listening sockets
- spawns and monitors worker processes
- handles graceful shutdowns
Worker Processes:
- accept connections
- handle HTTP requests
- serve static files
- manage keep-alive
NxLite uses the same model:
- a single master process sets everything up and forks multiple workers.
- workers share the same socket and independently handle connections using epoll + sendfile.
NxLite isn’t just an experiment. it’s a high-performance static file server with a UNIX-style process model and real-world efficiency.
want to test it out?

$BTC
continuation can be tricky so getting involved higher means being a bit patient to observe behavior at developing value during periods of consolidation.
would not be mad if $BTC constructively developed some form of balance up here now - could potentially provide alts some breathing room to drift higher.
if you zoom out a bit, this is beautiful.

I just built first working version my own mini-NGINX in C and stress-tested it with 100,000+ requests!
- 0 failed requests
- 80K+ req/sec sustained
- 10–20ms avg latency

I'm (still) working on the Playgrounds 2.0 for iximiuz Labs. Here is what we'll soon have:
- Up to 5 VMs, up to 150 GB of total disk space
- Multi-drive/fs playgrounds (ext4, xfs, btrfs, etc.)
- Multi-LANs playgrounds: A <-> B <-> C <-> D
- Your own container images for VM rootfs
- Kernel selection: 5.10, 6.1, custom builds
- And of course, persistent VM rootfs 🔥
The next release will take the platform to a totally new level and enable so many learning, teaching, and experimentation scenarios. If you like these features and/or want to support my work, you know the drill. Now is the best time to get a premium membership because my single-threaded brain can do either code or marketing, and the long development sprint has already started impacting the sales 🙃

There’s been a lot of talk about retail investors during this cycle, and here’s one more piece of evidence showing they remain relatively missing, despite BTC hitting multiple ATHs since 2021.
Today, we’re seeing the lowest number of addresses categorized as "shrimps" (holding <1 BTC) since 2021.
— Back at the 2021 ATH, there were around 590 000 shrimp addresses.
At the April 2024 ATH, that number had dropped to 490 000, and today, with another ATH just around the corner, we’re down to only 260 000.—
💡We can also observe that the 30-day average is evolving well below the yearly average.
👉🏼 This clearly shows a lack of retail enthusiasm, and further confirms that BTC network activity remains fairly weak.
While it's worth noting that some addresses may have changed category over time as they accumulated more BTC but this only concerns a minority.

I got tired of deobfuscating and decrypting #CypherIT AutoIT scripts and payloads manually each time, so I put together the script to decrypt the embedded payloads and deobfuscate the restored scripts ☺️ Hopefully, someone will find it useful...

A #CypherIT crypter is being used in #LummaStealer infections. This campaign is spread via various sources. The binaries use NSIS installers and AutoIt scripts. From an infection, we also saw a clipper payload targeting cryptocurrency wallets. Details at bit.ly/3Fibxse

Since a lot of you seem to have liked my previous challenge, here's a new one. The goal is, once again, to find a bug and leak the secret.
BTW all AI-generated responses failed quite spectacularly last time, so perhaps it's better if you refrain from using it.

🚨US hiring is at CRISIS levels:
US hiring as % of employment hit 3.4% in March, near the lowest since the 2020 CRISIS.
The hiring rate sits below the 2015-2019 pre-pandemic average of 3.8%.
A similar trend was seen in the 2001 and 2008 recessions.👇
