This blog is an unbelievable gold mine of information about networking, Linux, and other concepts. It's what I wish my own blog was in my head, if I could somehow summon the time and creativity.

Good. That's the point.

It's funny, though, there's literally an example of this in the picture located on the ENAC project page for this font in the flight plan screen:

Also seems to be more discussion of this point the last time this was posted:

It also seems like there's a "slashed zero" glyph in the font, though I don't know how to actually type it:

gVisor also has a complete userspace networking stack that you can pull in, which makes it a lot easier to do some neat things like run an HTTP server responding to packets intercepted via eBPF and sent to an AF_XDP socket, which would otherwise be a pain.

Finally. All I want for Christmas is a 5K, HDR, 120Hz display. I'm managing with 4K, 120Hz, and scaling to 2560x1440 in Mac OS, but with the latter option I lose HDR. I can't give up 120Hz after getting used to it on all my devices.

> I'd love to be able to run rootless quadlets within the system session.

Likewise. I'd also like to be able to run rootless quadlets with the DynamicUser= option. DynamicUser= has been a great way to restrict privileges for system services, and it just doesn't fit with podman right now.

> Because Kubernetes without operators is not Kubernetes.

Alright, so, what is it, then? I've been unfortunate to work at firms that generally have a minimal level of competency with Kubernetes, but across several billion dollars worth of firms, not a one has used operators in any capacity, but they leverage Kubernetes substantially. Help me understand the gap, would you?

Cynically, I feel like these details are often lost in the two-week sprint cycle or other realities of modern software development process. The Figma file didn't specify autofocus, the PM doesn't care about it, and the engineer just wants to close their ticket so they can move on to the next one. It's a login page, who cares? What revenue or business metric does it drive? Same reason the input field for the code doesn't have its input mode set to numeric (to show a numeric keyboard on mobile devices), and the same reason the email field doesn't have the email input mode set (to show the email input keyboard with @ and . prominently featured).

I've only had a brief stint in Java in my career, but I got to learn about and use jOOQ, and I think it's such a fantastic option in this space. I'm still a diehard SQLAlchemy fan, and I'd use it in Python-land. For Go, I think sqlc is a decent option, but it's no jOOQ. I'd love jOOQ for Go.

> Curious what others are using for 10Gb at home? I'm all ears and will be grateful if you have recommendations.

Lots of options. What’s your budget, both for purchase and power draw? How many ports do you need? 10GBASE-T or is SFP+ okay? How much noise can you tolerate (i.e. is this in a basement closet or right next to your desk)?

Recently moved to Seattle from NYC. I'm enjoying Seattle, but it's a joke of a city compared to NYC. Seattle's public transportation—while improving with light rail—pales in comparison. Seattle is, overall, pedestrian-hostile. There are neighborhoods that are themselves walkable, but sidewalks will disappear when walking between them, or you'll be forced into situations where you're uncomfortably close to high-speed traffic (e.g. the Ballard bridge).

Seattle has enough good food to keep me relatively happy (even pizza and bagels), but for any given cuisine, you might have one or two good options. Getting to them probably involves driving, and they're probably not open late or even open at all early in the week (maybe this is a pandemic artifact; I moved here in 2021). Seafood here is great, though. I think Seattle wins in that single category.

I think NYC's biggest win over Seattle (and every single other city in the US) is the combination of quantity, quality, and accessibility. You have some of the world's best food, shopping, culture, and jobs accessible to you at all hours of the day via a subway ride (or in many cases within walking distance). The city is your backyard: you don't need a huge apartment because there's a good chance you won't really be spending much time there.

That said, after 10 years there I grew tired of that lifestyle and wanted to spend more time outdoors and exploring the west coast. If you really enjoy the outdoors—hiking, skiing, mountain biking, climbing, etc.—then NYC is vastly inferior to Seattle. I may find myself back in NYC some day because I miss the things that it's the best at, but for now, I'm enjoying doing something different. I think it's very easy to fall into a hedonic routine in NYC.

I empathize with this so hard. I have an early first-initial-last-name Gmail account as well. It's both very generic in the United States, and when combined, a common first name in Brazil. It's nearly unusable at this point, but I've had it since 2004 and it'd be very difficult to migrate away from it. I have a filter to delete any email from a .br domain, but just the amount of Brazilian spam that makes it through is torrential.

How about the GitHub Student Developer Pack? https://education.github.com/pack

You get $100 in DigitalOcean credits. That's 20 months of hosting a VPS; plenty of time to figure out how to come up with $5 per month thereafter.

I'm glad other people are having luck with this, but I just couldn't get it to work with my setup. I'm wondering if it's because of the weird MTU and CGNAT on the connections I'd like to bond (300Mbps up and down municipal-ish WiFi).

I was able to get two OpenMPTCProuter installations talking to each other, but downstream traffic wouldn't balance across interfaces, and upstream was limited to 0.25-0.5Mbps (not a typo, and the links on their own have >300Mbps capability). I'll maybe try it again, but for now I have to add this to the pile of solutions that haven't worked for me (including VyOS WAN aggregation, ZeroTier multipathing, and Wireguard and ECMP).

How loud is that little Supermicro, though?

> schedulers like Kubernetes can also use your CPU and RAM limits to schedule containers. As far as I know, there's no equivalent tooling for doing this with fat binaries.

I much prefer the Docker and Kubernetes world, but you could actually do this (scheduling and bin-packing fat binaries) with Nomad's exec driver:

https://www.nomadproject.io/docs/drivers/exec.html

You can use the WiFi on these things from a surprising distance (hundreds of feet) with a proper antenna. Even with an IPSEC tunnel in place, one can achieve a connection with over 100Mbps upload and download with 5ms latency. That's much better than what most ISPs in NYC provide. And it's free. So, there's that.

CSS Modules have been revolutionary for us. I agree, it's a great compromise. I don't really see any reason to go to CSS-in-JS from here. It's scaled very well with our team and applications.

Sad that this isn't available as an on-premises solution out of the gate. We're stuck using internally-hosted HipChat for compliance reasons and it is absolutely awful. The desktop and web clients have only gotten worse over time. This confirms my worst fears that HipChat is basically abandonware.

> I'm adding to each node host a systemd service to create dm-crypt+LVM devices atop of each NVMe drive

That sounds cool; can you describe how you're using systemd for this in a bit more detail? I do this with an Ansible playbook when the machines are provisioned.

What are you talking about? No it didn't. It came with an adapter that has a female 3.5mm headphone jack on one and and a male Lightning adapter on the other end to allow you to connect headphones with a 3.5mm connector to your Lightning-only iPhone 7. To connect to a 2016 MBP, you would need the opposite—a cable which does not currently exist.

I love and live in NYC right now, but I wouldn't mind moving to Salt Lake City, UT. Political climate is a bit silly, but the outdoor recreation is just amazing. Skiing, mountain biking, climbing, fishing... all in your backyard. Cost of living is pretty low, but salaries/job diversity seem pretty low along with it, so I'll probably stay with NYC for a while.

Not to mention things like logging and metrics overhead if you're logging every request at multiple levels (application, NGINX, HAProxy).

This is... not my experience at all. I have a RAIDZ2 comprised of 6 4TB Seagate drives (the 5900RPM variety) and it can do about 600MBps read/write with moderate CPU usage on an Intel i3. A mirrored zpool of two Samsung 850 EVO SSDs can do nearly 1GBps read/write. That's not a particularly expensive setup.

I think there's definitely a bootstrapping problem here: microservices are great if you have something like Kubernetes, Nomad, Mesos etc. on which to run and deploy them, but you have to run your platform on something and be able to bring it back up if it goes down and that's where I think Nomad might have the edge.

`kj` has worked really well for me (except, actually, when trying to write a blog post about a recent trip to Reykjavik, but that's the one time it's bitten me versus the shitton of time it's saved). I also have `zkj` mapped to `<ESC>:w<CR>` to save AND exit insert mode.

Surprised to see no mention of "JavaScript: The Definitive Guide" (http://shop.oreilly.com/product/9780596805531.do). It's a big, heavy book but it's what really pushed me to a higher level of JS understanding.

I think the key is having the option to use the mouse, in addition to normal Vim keyboard shortcuts. If I'm switching back and forth between Vim and a browser, for instance, I have my right hand on the mouse already, and I can scroll with the wheel, select a tmux pane, copy and paste things, etc. very easily. If I didn't have that option, I'd have to switch back to the keyboard. If I have both hands on the keyboard already, I'm probably not going to use the mouse.

This is a tad annoying when writing comments with indented code blocks, since it pops up with every `@` you write, which in Coffeescript or Ruby can happen frequently. Great, otherwise.
