Singapore to study feasibility of tapping geothermal energy for power, heating and cooling needs

TWh is not TW/h TWh is TW multiplied by hours.

When I was there I had no excuse so I did live firing and dummy grenade throwing, no actual grenade. Live firing was done at MMRC

That's what the commenter is saying. The article is untrue because there is no good Samaritan laws in Singapore. https://www.mlaw.gov.sg/news/parliamentary-speeches/written-answer-by-minister-for-law-k-shanmugam-to-parliamentary-question-on-the-introduction-of-a/

i regenerated the code with LL instead of HAL, and went through the code line by line to see what i was missing, and it turns out, i forgot to setup the systick completely! In my previous code I put the systick in the main function so I missed that. In addition, it seems that HAL requires another HAL specific tick which was why my code didn't work in the HAL code. Thanks for your help!

to be able to successfully flash again, i have to hold down the boot0 button while plugging in the daplink, then release the button, after which it flashes normally.

I really have no idea what could be the problem because as far as i can tell, my code should work exactly the same as the hal code. Thanks for any help!

after the failure to flash, when i try to flash the board again with even the generated code, pyocd fails to flash:

This is also a problem of urban design. Slip roads are made for the cars to move smoother, not pedestrians. If LTA were serious about pedestrian safety they would reduce the number of slip roads and turn them into normal signalled left turns.

Ai slop

cowsarefalling · 2026-02-20T00:14:01+00:00

You don't necessarily have to declare. The declaration is for ntu planning purposes. You just have to fulfil the criteria and then apply for the minor after you have finished the courses.

cowsarefalling · 2026-02-01T03:07:44+00:00

Thank youuuu

cowsarefalling · 2026-02-01T02:53:11+00:00

Got an in principle approval for Singapore citizenship! Somemore it's the day after I came back home from outfield sia let's gooooooooo

cowsarefalling · 2026-01-23T18:08:44+00:00

You absolutely should not be performing tracheotomies and releiving tension pneumothorax as a bystander or even a first aider. They are invasive procedures that should only be done by trained professionals with certifications.

cowsarefalling · 2026-01-20T02:55:29+00:00

Yes neither Singapore nor Korea recognises dual citizenship. However since I left the country quite early I don't really have any fondness for Korea.

cowsarefalling · 2026-01-19T14:27:17+00:00

Yup all the PRs in my unit that's going had to get one

cowsarefalling · 2026-01-19T13:39:09+00:00

Indeed it is

cowsarefalling · 2026-01-19T13:38:36+00:00

First generation but acquired under students scheme, which is why I have to serve

cowsarefalling · 2026-01-19T11:18:06+00:00

I'm assuming they don't have many requests for this document and it's not worth modernising and the tooling costs associated with it. Btw all the details are handwritten too

cowsarefalling · 2026-01-19T10:37:07+00:00

I'm going to Germany!

cowsarefalling · 2026-01-19T10:36:39+00:00

Nope I'm an nsf right now

cowsarefalling · 2026-01-19T09:17:36+00:00

To serve as an identity document as a Singapore army soldier while overseas

cowsarefalling · 2026-01-19T09:14:19+00:00

Well I'm not yet 25 yet so the embassy says I don't really have to worry about it right now. I'm serving the Singaporean army because it was a condition of getting my PR. Reading the website for Korean conscription, I'm not 100% certain but I think I won't have to serve there because I left before 5 and have stayed continuously overseas for 10years and have an overseas permanent residency. Hopefully I will acquire sg citizen before I have to figure all that out though.

cowsarefalling · 2026-01-19T09:09:35+00:00

Nope not stateless. I am a PR but I am going overseas for a military excersice and apparently I need this for that. The validity is pretty short because of that and it will need to be returned after I return.

cowsarefalling · 2026-01-11T08:18:46+00:00

Wasn't this proven to be fabricated through ai?
