How much energy do islands spend compared to the rest of the world? Of course there will be some places where fossil fuels will be the only alternative. But using that as an excuse for inaction in the parts where we do have alternatives doe

I don’t know, even with good frameworks TUI interfaces are harder to do than simple CLI. From what I’ve seen, interfaces made with these framework aren’t replacing CLI tools, just augmenting them. In fact I think the use cases are usually c

Maybe you don't have access to a graphics server, or just want to add a small interface to a certain part of a bigger application/script that works in the terminal. For example, apt will show you TUIs sometimes when it asks more c

It's not as much about talent but about tradeoffs. I work in traffic monitoring tools (not censorship, just observability tools for infrastructure) there's always the decision of how many edge cases you want to cover vs how fast y

Except that there should be only one way to make a filename from a string. Maybe some options like "allow_spaces" if needed but the point of DRY is not only to share code but to share algorithms.

How do you test 8 lines of regex inside a function that does more things? And what's easier, to write and read the function name or copy-paste the lines with the comment (if the comment explaining what that piece does is even written,

I think that drawing conclusions from these examples is not productive at all. In the wild we're going to see functions such as def make_string_filename(s): # four lines of regex and replace magic so that we have code

Yes, as someone outside the US, the fact that this is a thing is just... weird. When I go to the hospital I'm already worrying about health, I'm thankful I don't have to worry about money too.

For me the interest comes from seeing the speed boost between regular kernel/optimized kernel/DPDK. What you put behind the RX layer doesn't really matter, but it's good to see numbers and things to do when your RX syste

I wouldn't say XDP is an alternative to DPDK. XDP severely limits what you can do as you insert code inside of the kernel. DPDK exposes the NIC to regular user code so you can do what you want. XDP is useful when you want to modify wha

> If I recall correctly, DPDK abstractions themselves cost a bit of NIC performance, so it might be interesting to see a comparison including a raw NIC-specific kernel bypass framework (like the SolarFlare one). DPDK performs fairly well
321.
by gjulianm 4y ago
That's not the reality. The kernel network stack does a lot of things that for some applications are not needed, so DPDK is used for those cases when they need very high performance. For example, packet capture, routing, packet generat

I mean, you still have to invest time on putting k8s to work, get people skilled with it, maintain and debug the problems... If Kubernetes didn't cost anything to deploy I'd agree that using it is the better idea, but it costs tim
