Those cost money too

Four months of prison? It sounds like the man is disconnected from reality but hardly a real threat to society.

Kinda depends on where you live but there often is an excess of hydro and wind power overnight.

It’ll depend on how efficient your phone charger is vs your PC PSU. Looking at some charts, it’s a very close battle but generally the phone charger seems to win out. Probably because it’s more optimized for its max power output, whereas the PSU needs to support a wider range of loads.

The amount of heat this will add to your case is negligible. We’re talking 15% waste on a 20W load, so 3W worth of extra heat. And that heat is produced in the PSU.

Even the article acknowledges that “The city-state has excellent public transport links by bus and subway”. Clearly the city realizes they are running out of space and want to prioritize people over cars. The remark at the end - " your own family comes first" - just ends up sounding selfish and anti-social.

It does suck that it caters to the rich rather than the needy but taxation is just how you deincentivise certain behaviors in a capitalist society. Hopefully Singapore counters this with subsidized special transport for the handicapped and elderly.

The general consensus in the media is to not name or talk much about the shooter. It gives other troubled kids the opportunity to see them as a role model.
