A: comfy, over the ear gaming headphones

I have a few alternatives, with different pros and cons. I have extensive first-hand experience with each of these products. SteelSeries Siberia 800 / 840 First, a little history. SteelSeries launched the "H Wireless" headset a couple years ago. It's a wireless headset with a basestation, with ...

Dog

Also should have not forgotten my other USB thingy

Also should have brought my SATA bay thingy

Also shuold have brought my CD drive thingy

DANGIT so many thingies so little thingy

Argh I miss my thingies

DavidPostill

@Dog You need a thingy to keep a list of thingies to remember to take with you ...

Dog

Kinda sucks when you move house but don't move your thingies with you

djsmiley2k

erm

why would you not move your stuff??

Dog

@DavidPostill I have one of those, I use Google Keep

But I keep forgetting to put thingies into Keep

@djsmiley2k Because I haven't had time to do it yet

djsmiley2k

ah

still in a state of 'moving' ?

Dog

16:16

Yes

Hence my thingies are all in different places

bwDraco

Are you talking about the Seagate Innov8, which is completely bus-powered and has an internal battery to supply the extra power for spinning up the drive?

(USB 3.0 or later is required—the drive will not work on USB 2.0 due to power requirements and will signal an error if it is plugged into a USB 2.0 port. Not all USB Type-C connectors support USB 3.0; the port is just a connector that supports USB 3.1 but does not mandate support for SuperSpeed.)

djsmiley2k

oh that's not so cool D:

DavidPostill

@Dog lol. So you need another thingy to remind you to use and update the other thingy which is the list of thingies.

bwDraco

hmm. USB-PD of at least 1.5A@5V is actually required.

djsmiley2k

yey windows updates

Dog

Dangit the USB thingy isn't working

Serves me right for buying the cheapest USB thingy on Amazon

Dangit, my favourite local computer shop in Edinburgh's closed

Hmm, OK it works, just takes like 5 minutes for the drive to show up :-/

Can you make conky toggle like a widget

Actually the battery on the Nexus 9 is not fully charged. The full charge capacity seems to be closer to 6380 mAh, more than 95% of original charge capacity. This is excellent given the age of the device.

Also:

1 hour ago, by bwDraco

I am able to get detailed battery status through /sys/class/power_supply_bms. Current full charge capacity is 2538 of 2704 mAh (93.9%), computed using charge_full and charge_full_design.

It should be /sys/class/power_supply/bms.

As for my Nexus 5X, when charging is disabled, it seems that the battery still discharges when plugged in, albeit very slowly (according to Ampere). Regardless, being able to keep tabs on the battery and even programmatically disable charging lets me maximize battery service life.

This is because I can tell the phone to stop charging at a certain charge level since full charges are stressful on the battery. While it's not as good as automatically stopping charging at a certain charge level (e.g. 80%), software charging control means I can keep the phone plugged in and manage charging without having to disconnect the charger repeatedly or repeatedly charge and discharge the battery near the target battery level.

Yet another park of root: being able to extend battery service life.

Your thoughts on charge control? I wish more devices exposed these sorts of charge controls so that I can extend battery service life...

Battery management system

A battery management system (BMS) is any electronic system that manages a rechargeable battery (cell or battery pack), such as by protecting the battery from operating outside its Safe Operating Area, monitoring its state, calculating secondary data, reporting that data, controlling its environment, authenticating it and / or balancing it. A battery pack built together with a battery management system with an external communication data bus is a smart battery pack. A smart battery pack must be charged by a smart battery charger. == Functions == === Monitor === A BMS may monitor the stat...

In Kernel Adiutor, I added a switch custom control to manage this.

djsmiley2k

Hmmm

but what if it ALREADY stops at 80%?

bwDraco

No it doesn't. Charging normally stops at 4.35V, which is a true full charge.

djsmiley2k

you've removed the battery from the device and tested it yourself manually?

what if teh battery is actually 4.5V ?

:)

bwDraco

That's what the system is reporting. No, I don't expect the BMS to be lying about voltage.

I could probably get around 20 more hours of fun out of that game even if they don't improve it, so I'll probably re-buy it again once it's at least 50% off during some sale.

$60 for that is ridic
