Bokeh doesn't have different blur for different circles, it's always projecting the exact shape of the aperture.

Oh I really enjoy it when I get random emails from people that have read my posts and have occasionally mailed maintainers of software projects that it is working perfectly for me. It's always a nice change of pace from bug reports.

Oh that looks incredibly similar, thanks for the tip!

Author here, the best solution I think would be just ripping the temperature sensor from the battery pack and soldering it to the contact in the microphone instead, then you can just pop in regular rechargable batteries and it'll work. No need to add lipos to this.

I'm glad most of my music gear isn't battery powered. I do have a painful amount of different camera chargers though...

Linux from scratch is quite a lot of fun, did it a decade ago and learned how to bootstrap a linux system after installing Archlinux got boring. Never went past the initial "get a working" system stage though.

Now I'm building LFS/BLFS again but hacked the Alpine package manager into it to actually be able to install multiple machines with this and crossed the point where I'm daily driving it on my laptop

Ah you've never encountered /dev/null not existing yet, so when you try to trash data it will actually create a normal file there so every other program that uses it will actually append that file.

Luckily it's usually a tmpfs

This does happen, but it seems to depend on the ISP. In the Netherlands I've seen ISPs block the internet connectivity when they've detected infected devices, sometimes they send a letter before blocking and some ISPs seem to dump your internet connection in a captive portal. In all these cases it's been enough to call the ISP after finding the problem and you're connected again minutes later.

I'll have you know my grandma was using Linux just fine... was certainly a lot easier than windows changing random UI elements every time.

New comment by MartijnBraam in "The value of bringing a telephoto lens"

MartijnBraam — Sat, 13 Sep 2025 16:20:06 +0000

I always bring my telephoto lens. Since moving to a full frame camera I'm using a 70-300 most of the time and I rarely want a wider lens, more often I wish I brought my 600mm instead.

I also brought a 85mm prime which has been a lot of fun, while at the same time I've been lugging around a 35mm prime and barely used it.

You don't use them normally in the US, I've been referring to europe/amsterdam or europe/paris all my life in Linux installers and various equipment. I've never ever encountered netherlands/amsterdam or something like that.

Magic lantern is amazing. I'm still hoping a project grows for the other camera brands since I only have Nikon and Panasonic cameras.

Both cores are actually ARM cores, but you can switch both cores to be RISC-V cores as well on boot.

New comment by MartijnBraam in "Don't pick weird subnets for embedded networks, use VRFs"

MartijnBraam — Thu, 21 Aug 2025 20:22:59 +0000

Allocating a subnet is way further away from reality for most people than configuring one router feature on the router they're using.

There's also a lot of people that configure these devices (or linux routers) themselves but have never heard of VRFs, you got to learn about them somewhere so I just hope this helps some people :)

MartijnBraam — Sat, 09 Aug 2025 01:10:25 +0000

Hah I also have a smartphone prototype here powered by a single 18650 and I've already seen one of them turn into a smoke machine because the holder has protruding pins and doesn't fit most protected cells...

Two 18650s also sounds like it would be heavy for a badge

New comment by MartijnBraam in "Telephone colophon: Or, how I overengineered my call audio (2020)"

MartijnBraam — Fri, 01 Aug 2025 10:21:53 +0000

That's a lot of software setup for something that can easily be done in hardware. I've been over engineering things for years now.

For my mic I have also an sm57 feeding into a dbx286 hardware mic preamp and dynamics. Then feeding that into my audio interface for calls that also gives me a knob to mix in my mic into my headphone signal. This all gives me zero latency monitoring off all the gates and compression. Then for the output signal I have a seperate audio interface I use with all the web calling applications that sends the audio of all other people in the call to o another compressor that levels out their volumes. Then that is sent through a tc electronic multiband compressor unit to fix the really dull mics some people have. This is then mixed with the stereo output of all other applications on my audio interface again.

This way I have consistent audio no matter what OS I'm booted into at that moment.

MartijnBraam — Sun, 13 Jul 2025 09:55:17 +0000

Maybe the CVE is being ignored because it's not such a big issue at all? It's already possible to cause a train to brake and make a disruption by pulling any of the emergency breaks inside it.

It would be great if you could just order them. Mine are also falling apart... I've replaced them with FOSDEM shirts now

I nat IPv6 on one of my servers because having seperate ipv6 for VMS but the same IPv4 has caused some issues with running mail servers and certificates. If only I could drop IPv4 completely
