First version was a three layer VM monster, with the main entrance done as HTTP proxy written in PHP.

I don't think you can buy a single "MI300X" unit, right? Only the box with x8 of these at a cost of ~250K EUR.

> Across all tested generations, divergent paths serialize linearly with the number of paths k, following T(k)≈sk with no super-linear reconvergence penalty. Warp execution efficiency falls as 32/k, the penalty is independent of occupancy, and predication removes the serialization cost

So... Nvidia did a good job?

There is more! I started to figure out how ADC/DAC chips actually work. I believe our CM6533 and its competitor the CM108 both use delta-sigma. The output isn't a staircase of those samples but a rapidly switching (MHz rates) 1-bit modulator (think: PCM) output, and a final analog filter smooths it into a continuous waveform.

New comment by majke in "US citizen charged after GrapheneOS phone wipes during airport search"

Many countries now assume you have a phone. For example getting UK visa requires a smartphone. I don't think going without a phone is feasible nowadays.

Another question is if going with a burner phone that has just sim card and bank card, sufficient. But then you need appleid/google account on the device, and this again links back to your phone number, and it's not easy in practice to have proper clean device.

I'm a heavy user of NVIDIA LOP3 instruction (uint32). I wonder when AMD will finally support it well.

If you want to know more about the cache invalidation in the whole pipeline of DNS requests, take a look at this

https://blog.cloudflare.com/tld-glue-sticks-around-too-long/

I hinted there how the NS chain of lookups works from . to your domain. The point is that we wanted to be able to move name servers around the ip addresss, but that wouldn't work for many domains. So - in some contexts moving IP's rapidly is possible, in some it's not. Fun.

New comment by majke in "SOCKMAP - TCP splicing of the future"

majke — Fri, 26 Jun 2026 08:35:33 +0000

sockmap has been through a lot of changes since then. Some done by CF (hi Jakub!) some by others, including bytedance and isovalent.

Recently there has been a push to figure out the backpressure situation, so it's worth checking again.

This is great. So proper 386 on an fpga? How cool is that.

> A lot of self-hosters running CF tunnels because they don't know better also contributes.

Are you saying CF documentation is better than Computer Science / Networking education resources? Why don't people know better? I thought the tunnels are mostly used to bypass NAT's.

> Static blogs hiding behind bot protection

I'm not sure what is the proportion of the static vs dynamic sites, but I would argue that for wordpress CF is adding real value.

(I'm ex CF) This is backwards. Nobody "allowed" anyting. CF serves a customers need. You can argue with the solution but you can't argue with the core problem. It's more healthy to start the conversation of _why_ CF services are valuable.

I've had more success. Flipper taught me about sdr, and I was able to reverse quite a lot from my garage door pilot. Then I went on an adventure of cracking Keeloq cipher, and I haven't stopped since.

New comment by majke in "Defer available in gcc and clang"

majke — Fri, 20 Feb 2026 07:10:01 +0000

Not necessarily. In classic C we often build complex state machines to handle errors - especially when there are many things that need to be initialized (malloced) one after another and each might fail. Think the infamous "goto error".

I think defer{} can simplify these flows sometimes, so it can indeed be useful for good old style C.
