Not sure about GreaseMonkey, but V8 compiles JS to an IL.

Nodejs has an emit IL debugging feature to see the emitted IL code.

How much of that is cached state based on the percentage of ram available?

An alternative definition: a real-time system is a system where the correctness of the computation depends on a deadline. For example, if I have a drone checking “with my current location + velocity will I crash into the wall in 5 seconds?”, the answer will be worthless if the system responds 10 seconds later.

A real-time kernel is an operating system that makes it easier to build such systems. The main difference is that they offer lower latency than a usual OS for your one critical program. The OS will try to give that program as much priority as it wants (to the detriment of everything else) and immediately handle all signals ASAP (instead of coalescing/combining them to reduce overhead)

Linux has real-time priority scheduling as an optional feature. Lowering latency does not always result in reduced overhead or higher throughout. This allows system builders to design RT systems (such as audio processing systems, robots, drones, etc) to utilize these features without annoying the hell out of everyone else.

Yeah I completely forgot about the consumer side of things. I was expecting there being Cisco iOS/FRR router configs, not a full web dashboard.

As someone who works with 100Gbps networking:

• why the heck do these routers run Lua of all things???

systemd tries to unify a Wild West situation where everyone, their crazy uncle, and their shotgun-dual-wielding Grandma has a different set of boot-time scripts. Instead of custom 200-line shell scripts now you have a standard simple syntax that takes 5 minutes to learn.

Downside is now certain complicated stuff that was 1 line need multiple files worth of workarounds to work. Additionally, any custom scripts need to be rewritten as a systemd service (assuming you don’t use the compat mode).

People are angry that it’s not the same as before and they need to rewrite any custom tweaks they have. It’s like learning to drive manual for years, wonder why the heck there is a need for auto, then realizing nobody is producing manual cars anymore.

iirc the bad UA filter is bundled with either base-http-scenarios or nginx. That might help assuming they aren’t trying to mask that UA.

Pretty sure expiry is handled by the local crowdsec daemon, so it should automatically revoke rules once a set time is reached.

At least that’s the case with the iptables and nginx bouncers (4 hour ban for probing). I would assume that it’s the same for the cloudflare one.

Alternatively, maybe look into running two bouncers (1 local, 1 CF)? The CF one filters out most bot traffic, and if some still get through then you block them locally?

I’ve recently moved from fail2ban to crowdsec. It’s nice and modular and seems to fit your use case: set up a http 404/rate-limit filter and a cloudflare bouncer to ban the IP address at the cloudflare level (instead of IPtables). Though I’m not sure if the cloudflare tunnel would complicate things.

Another good thing about it is it has a crowd sourced IP reputation list. Too many blocks from other users = preemptive ban.

According to this post, the person involved exposed a different name at one point.

Cheong is not a Pingyin name. It uses Romanization instead. Assuming that this isn’t a false trail (unlikely, why would you expose a fake name once instead of using it all the time?) that cuts out China (Mainland) and Singapore which use the Pingyin system. Or somebody has a time machine and grabbed this guy before 1956.

Likely sources of the name would be a country/Chinese administrative zone that uses Chinese and Romanization. Which gives us Taiwan, Macau, or Hong Kong, all of which are in GMT+8. Note that two of these are technically under PRC control.

Realistically I feel this is just a rogue attacker instead of a nation state. The probability of China 1. Hiring someone from these specific regions 2. Exposing a non-pinying full name once on purpose is extremely low. Why bother with this when you have plenty of graduates from Tsinghua in Beijing? Especially after so many people desperate for jobs after COVID.

Iirc the specific reason behind this is

• sudo by default requires a tty to run
• vim’s bang spawns a tty to execute commands
• nvim’s bang executes the command directly, then pipes the output to nvim

As a result, sudo (without args) can’t work in nvim as it doesn’t have a tty to prompt the user for passwords. Nvim also used to do what vim did, but they found out spawning the tty was causing other issues (still present in vim) so they changed it.

A tumbleweed rolls in the distance…

Both Bluetooth and BLE are perfectly fine protocols. You won’t be able to design much for short distance with that much power savings otherwise. The main issue is that for any protocols like this you would most likely need to put it in the 2.4ghz unlicensed band. And that’s predominantly used by wifi these days.

There are totally more flexible options. Just don’t mind the front falling off. It’s totally normal!

Simply changing the binary worked for me. Been more than 1 month and no migration issues.

It does still show gitea branding, however.

My suggestion would be to try compiling the kernel locally.its highly likely the one packaged in your distro contains extensions that you don’t have. Doing a local native compile should rule that out pretty quickly without having to disable any additional features.

Look at the line with the asm_exc_invalid_op. That seems like a hardware fault caused by an invalid asm instruction to me. Either something wrong is being interpreted as an opcode (unlikely) or maybe the driver was compiled with extensions not available on the current machine.

OP, how old is your CPU? And how old is the nic you are using?

Edit: did you use a custom driver for the NIC? I’m looking at the Linux src and rt_mutex_schedule does not exist. Nevermind. Was checking 4.18 instead of 6.7. found it now. The bug is most likely inside a macro called preempt_disable(). Unfortunately most of the functions are pretty heavily inlined and architecture dependent so you won’t get much out of it. But it is likely any changes you made in terms of premption might also be causing the bug.
