From a nerdy standpoint, SPL competition is AMAZING.
The amount of math that goes into a proper enclosure design and to fit it properly in a vehicle is really fun. It's not going too much further than geometry, but theory can go far further. The differences that exist in rounded vs square ports vs flared ports, sealed vs ported vs bandpass box design, standard vs inverted vs isobaric mounting... the list keeps going.
To get the loudest, it's not always about adding the most power possible. The enclosure, capabilities of the subwoofers, power delivery, even the acoustic properties of the shape of the vehicle itself are all factors. Adding the weight of all the components usually means the vehicle's suspension needs upgraded. Higher output (or multiple) alternators need to be able to produce enough power. Extra batteries are added to support peak power for longer periods. Gaining DBs at high levels is exponentially more work as you continue to go higher.
The DB Drag events really showcase the hobby best. Much like how people tinker with their engine's performance and test it at a drag strip to see just how fast they can go, others tinker with how loud they can get their bass to go.
As noted by other commenters, these systems can be annoyingly loud when used at late hours, busy locations, or residential areas. The exact same can be said of people driving their cars way too fast / aggressively. Any hobby needs to have situational awareness to be respectful of its surroundings.
Anyone interested, https://www.diymobileaudio.com/ is likely one of the best information sources, both for current and historical SPL information.
On arch, I definitely get better gaming performance than the stock kernel. The liquorix repo's arch kernel doesn't play well with libvirt - that's about my only gripe.
Xanmod kernel seems to have all the gaming improvements and still plays nice with libvirt though.
Previously dual monitor, 24" 1920 x 1080, portrait left, landscape right. left was usually for email and chat, right for coding and browser.
Now it's a single 40" 4k tv as my display. Using gridmove to easily partition the screen as needed. It's like have 4 1080p screens with no border. Only downside I've come across is some screensharing apps will always share the entire desktop when sharing a single app (webex is worst offender) - just the app window will be shown, but with massive greyed out background. Can be fixed by changing desktop res, just an annoyance.
Moving to a single massive screen has honestly lead to better productivity, but i possibly attribute that more to gridmove than overall screen real estate.
I fix that by maximizing whatever app I'm sharing and upping the zoom. It looks comically large on my screen, but normal to the rest of the folks on the call.
For screen sharing I use Picture-in-Picture mode of my 43” 4K monitor (Acer DM431K) to give me a separate 1920x1080 screen to share when required. That way it is at the right size and resolution for everyone.
Yes. One HDMI 2.0 to give me 4K@60Hz and then one usb-c to HDMI (or is it DP) for the PiP.
Only one input on this specific monitor can do 4K@60Hz, all the others are 4K@30Hz or good refresh at lower resolutions.
Takes 20 seconds to enable the second display in display settings and then pick the right input for the PiP mode on the monitor (it has a remote). Most of the time I have my personal laptop displaying in the PiP frame lower right. The remaining 3/4 of the screen is my work area.
No censorship can make whoever yells the loudest be the most heard, which can snowball into millions of ramifications.
I'd like to go back to the early internet days where people had to at least make a geocities site to spread their word, with no financial incentives to getting more clicks or viewers. It wasn't perfect, but you had to be seeking that group / audience rather than having it thrown in your face everywhere.
AWS offers throw away accounts during immersion days, jam sessions, etc (especially at re:invent). It would be great if these were extended to the general public, even if at a small fee.
There’s a service like this called Qwicklabs that I have been using for GCP training. You load a time limited lab and get a new set of credentials only for that session. After the timer is up, poof everything is deleted.
