- Comment on Sugar vs baking soda to neutralize acid in canned tomatoes? 3 weeks ago:
yeah, baking soda works but you have to be careful with the amount you put in them or they’ll taste very bland after…

Thanks for the interesting write-up!
- Comment on Weird PC PSU Capacity 1 month ago:
Thanks, I’ll have a look. It’s an universal mains power supply with no voltage switch.

How were you measuring the current in the power cable? Is this with a Kill-o-watt device or perhaps with a clamp meter and a line splitter?
For the current both with a line-splitter+clamp and checked with an in-line meter. For the power factor, since I don’t have any actual instrument to measure It, and I just needed a ball-park figure to discern actual consumption from a capacitor, I used this diy method: www.giangrandi.org/electronics/…/cosphi.shtml , which measured 0.04 ( with great approximation ).
As for why there is a capacitor across the mains input […]
I have the basic on how a switching power supply work, but I was asking because it seemed weird to me that commercial appliances didn’t take any stand-by meaures to avoid “keeping the wires warm”… is this the norm?

you’d almost certainly notice the change in gravity.
Really? can you actually percieve the sun gravity? Do you mean that we would get like a tsunami beause of the tidal effect? Now I kinda want a documentary about this.
- Comment on If hot air rises, why is it colder at the top of a mountain? 7 months ago:
Sorry i didn’t meant to be misleading, just to discuss! However after checking on Wikipedia en.m.wikipedia.org/wiki/Lapse_rate I omitted that lower pressure air at high altitude absorb/emit less heat, but what I wrote is not wrong, just incomplete…
- Comment on If hot air rises, why is it colder at the top of a mountain? 7 months ago:
Without checking, I would say that it’s because the heat dissipate away from the planet and the hot air will eventually cool down while rising? My understanding is that it’s hot near sea level because it’s where the heat from the sun get reflected and radiated from the earth surface, correct me if I’m wrong…

Exactly, making everyone to switch over to something else is impossible…l’ll uninstall it as soon as they roll this out

In one of my jobs, they were automatically locking any push 2 hours before the shift ended.

The main downside of Tuta free for me is that you can’t create filters for free. The main downside of proton free is that you can’t remove their signature…
- Comment on Open source community figures out problems with performance in Starfield 1 year ago:
I’ll give a different perspective on what you said: dx12 basically moved half of the complexity that would normally be managed by a driver, to the game / engine dev, which already have too much stuff to do: making the game. The idea is that “the game dev knows best how to optimize for its specific usage” but in reality the game dev have no time to deal with hardware complexity and this is the result.
- Comment on What do you use to manage operating system images for installation on new laptops and workstations? 1 year ago:
I only tried this with windows which works fine: on restore Clonezilla has an option to rescale partitions on the fly to fit the destination drive. For drivers, windows detect changes and update them the first time is started on the physical machine.

I get it about the corporation issues but do you even dislike firefox? Do you think it would be positive to have one less alternative to chrome? What browser do you use?
- Comment on What do you use to manage operating system images for installation on new laptops and workstations? 1 year ago:
Clonezilla. I usually prepare images in virtual machines and restore them on physical drives.

On desktop, I’m really wondering why people use it. I mean it’s not pre-installed for windows, what makes people choose Chrome in 2023?
