Help fixing a bad soundproofing window with roller shutter

I have these soundproof windows that don't work very well. While the glass panel part actually works okay, I found that a lot of noise passes through the compartment where the roller shutter is kept. Here's a picture: https://imgur.com/a/R6K4UPl

After opening the compartment I found that there's basically no soundproofing there at all. It's hollow compartment made of metal, with a very thin layer of something lining the inside. (Image of the inside also available: https://imgur.com/a/R6K4UPl )

So basically that makes the glass soundproofing kind of useless since the sound just goes through the metal compartment at the top.

My question is: are there ways I can manually fix it? My intuition is to just get some insulating material and line up the inner chamber. But I'm not sure what to put there. I could also put something on the outside. It wouldn't be pretty, but as long as it works I wouldn't mind.

Quais são os horários atuais do people mover de GRU?

Vou usar o aeroporto de Guarulhos essa semana e queria usar o metrô, mas só se eu puder pegar o people mover (aerotrem), porque aqueles ônibus demoram demais e sempre lotam. Alguém sabe se já está funcionando em horário integral? Quando eu procuro online só vejo notícias com horários conflitantes.

Xreal One started drifting a lot this week

I've had the Xreal One over a year now (since Feb 2025 iirc) and there has always been a bit of sideways drift here and there, but nothing too bad. It used to require me to re-center the screen perhaps once every 30 minutes or so, which I found pretty acceptable.

However, this week it seems like the level of drifting increased significantly out of the blue. I've been finding myself re-centering an average of once every 10 minutes, and sometimes I have to keep re-centering constantly for a couple of minutes straight until it finally stabilizes.

Does anyone know what could be happening? I haven't dropped it or anything. I have been traveling with it though (which is what I bought it for in the first place, so the traveling isn't new (and I always keep it in the case when doing so))

If if matters, I have the 15.1.03.165_20260105 version of the firmware (and unfortunately I can't update it because I use only Linux...)

How do I check into a Copa flight operated by Volaris

I'm trying to check into a Copa flight that's operated by Volaris. On the Copa website they say the check-in has to be done through Volaris, but on Volaris they can't find my flight with the reservation code + last name. I'm trying to call Copa to ask but the wait is over 3 hours!

I'm really trying to avoid checking in at the airport because I won't have much time to arrive early. Does anyone know how I can check in online?

Faded colors on Neo reader after latest firmware update

I updated the firmware to the most recent version a couple of days ago and noticed since then that colors in Neo reader are really faded. I checked its settings and they seem to be the same as before. Even then I turned some knobs around but still looks really faded.

Not just that, when I annotate with, say a red pen, the red appears normally at first. But if I go to another page and then come back, then suddenly it's faded again.

Has anyone experienced something similar? I already restarted the device. Not really sure what else to try.

TV stick for stremio for traveling abroad

I've been an old chromecast stick to watch stremio while I'm traveling. However, that chromecast is pretty slow these so I'm looking to upgrade. My thinking is to get an onn stick, since it seems to be as small as the chromecast. But most of them claim they're "U.S. Compatible only". Most of my traveling happens outside the US, so I'm afraid I won't be able to use it while I'm out.

Does anyone have any suggestions? My only requirements is that it needs to be small (a stick really) and it needs to support stremio.
