In the last few months I haven't run a lot because of the weather (hot and humid) and because of a crap ton of uni work for my thesis. Yesterday I finally managed to run a 10k after literally months. With respect to my usual form it was terrible, i run a 6:10min/km when usually I'm well below 5:45, but considering I had run like twice in the past month and a half and had been months since my last 10k I'd say it was a good result

I started using OpenTracks a couple years ago and ditched runtastic (i keep calling that, it's been adidas running for ages) when I discovered it made my runs public, with gps data and all, for the social features of their app. OpenTracks is FOSS, I got it from fdroid, the data stays on your phone, you do what you want with it. And most importantly it only tracks your activity, just that, no social media crap.

Then again if you don't want to track your runs just don't, I personally do it because I like to see my progression and to keep notes to myself on how/what/when i eat/sleep/etc effects my runs and stuff like that

Was it in "Ubik" that people had to pay a fee every time they wanted to use their domestic appliances or even open the door to their own house?

Not one in particular, just the first thing that came to mind since I use it a lot on linux. I even use NewPipe on android, didn't even remember it had an option to download

Nah 85/90 degrees is perfect for the job. Much better and more uniform than a heatgun, let alone a hairdryer

Is that a motorola moto z2 play? I owned that phone and I used to disassemble it just like this!

Edit: saw in another comment that it's a z4. The camera did look strange for a z2 at a second glance

I wonder how it affected traffic in c/[email protected]

While I don't remember his name, I remember there was a Darknet Diaries episode about the researcher who first investigated the problem. The episode was very thorough, I liked it a lot. I also don't remember the name of the episode, so I guess this comment is kinda useless

What Calendar and To Do solution do you recommend? in c/[email protected]

I second this

Also dumbest idea, have you tried a brand new spool of PLA? Just to exclude an incredibly wet filament. Because that can cause all sorts of problems

[Advice Request]: managing thermal pads for SMD components in custom PCB (sh.itjust.works)

Hello everyone, I need some advice.

I am making custom PCBs for a project of mine. It's basically for a little remotely controlled robot using little DC motors. I chose the Seeed Studio XIAO ESP32C3 as the uC since it has inbuilt wifi/bt, 3.3V regulator that I can use to power the motors (can source up to 700mA) and lipo charging management (the robots will run on battery). As you can see from here, the microcontroller is surface mounted and the pads for the battery are on the bottom layer. Same story goes for the thermal pad of the microcontroller and the thermal pad of the motor driver (datasheet). I have worked with SMD components in the past and can solder them by hand, but I have never worked with SMD components that have thermal pads on the bottom layer. My question is: how to manage (route?) them? My PCB is 2-layer and I was planning on having both layers filled with a ground plane. Do I just connect thermal pads to the ground plane and call it a day? Wouldn't that make the components hard to solder with hot air? Do I make an isolated polygon that only acts as a thermal pad?

Speaking of soldering is even hot air the way to go in this case? My PCB has components on both sides, and I was planning on ordering stencils together with the boards and using solder paste, placing the components and then using hot air to solder the components in place. I thought a hot plate would be better but I don't have access to one and I don't know how that works with components on both sides.

I attached some photos of the PCB in Kicad, and here's the git repo. If it is of any help, I'm planning of having them manifactured by JLCPCB. It is also my first time using KiCad, so go easy on me :)

Thanks!
