Devices of Questionable Ethics #1 and #2

04/02/21


#1

A programmable circuit connected to a button, 7-segment display, and buzzer, small enough to be placed inside an oral thermometer. And in fact, is meant to be placed inside an oral thermometer.

When pressed once, the 7-segment display lights up and starts displaying an ascending sequence of numbers with one decimal place. After 5 seconds, it beeps and shows a random value greater than 35.0 and lesser than 37.5. The seed for the pseudorandom number generator is controlled by the potential difference of the battery.

When pressed twice in quick succession (within 0.5 seconds), the 7-segment display lights up and starts displaying an ascending sequence of numbers with one decimal place. After 5 seconds, it beeps and shows a random value greater than 37.7 and lesser than 42.0. The seed for the pseudorandom number generator is controlled by the potential difference of the battery.

Use case: perhaps say maybe in the occurrence that you happen to live in a police state and there is some zombie invasion going around and people who have been bitten by the zombie have a very high metabolic rate. I don’t know why one would want to be identified as a soon-to-be zombie, but ok.

 

#2

Mini remote-controlled blinds for your car plates.

Or if that’s too sus, a remote-controlled sliding “door” for your car plate. At the click of a button, a hidden car plate emerges and slides over your actual car plate, thus covering your actual car plate and placing another faux car plate over it.

 

Not sure if these are more or less questionable as compared to the strap-on-corset-TENS-back-brace-filterless-scuba-suit that I once tried to design.

It Will Settle Itself Somehow

 030721   At the start of the semester, or rather, before the start of Year 2 Semester 2, I had set myself 3 non-academic related goals to accomplish. Is it hubris? Anyway, I knew that the academic grades can’t be too bad, considering my past record. So, I didn’t concern myself with setting goals for academics, I just let it be, and take it as it comes while trying my best. I guess even amongst all that rock-bottom self-confidence, all that moping, all that saying that I’m gonna die, all of the crying, I guess somehow, I subconsciously know that I can actually do it, quite well, satisfactorily enough. Except this voice is drowned out by the other hostile voices, which are much louder and more aggressive. “Intrusive thoughts”, as they are termed. Well, that was quite a tangent, but I must go back to the 3 goals I set for myself. 3 things I needed to do. 1.        Start getting help for my mental health. I guess it mostly means starting to get on meds. And therapy. But mainly the

A Quick Lament on Singaporean Vegetarianism

12 Jan 2019 Vegetarian in Singapore is usually driven by religion, specifically Buddhism, which about a third of Singaporeans profess to be adherents of. And many Hindus who are also vegetarian, although the percentage of Hindus is much less. And according to dharmic religions, alliums, a type of root vegetables, are not vegetarian. the Buddhism rationale is that these plants contain compounds which excite and distract from the peace and enlightenment process, as well as making the breath stink and the person unpleasant. Jainism furthers the concept of ahimsa to say that plants are hurt and die when they are picked from the ground, and little bugs are also killed in the process, (hence fruitarianism does least harm). The excitability claim is reminiscent of Fully Raw Kristina’s avoidance of alliums because they are supposedly excitotoxins and destroy brain cells. Hence in the case of Singaporean vegetarians, they usually avoid garlic, onions and ginger. A pity, really, when garlic

AY2020/21 Semester 2 Module Ramblings

 posted: 03/07/21 (last edited: 17/06/21) Officially falling prey to the Dunning-Kruger effect? Interesting . CS2105 Introduction to Computer Networks MCs: 4 Expected Grade: A- Actual Grade: A Workload: Very manageable if you start your assignments early The lecture slides call this module “An Awesome Introduction to Computer Networks”. Reality is not too far off, I guess. Doesn’t really go in depth to each part of networking, but this is an introductory module, after all, so that’s acceptable. Knowing the difference between UDP and TCP is important for technical interviews, so this is a good module to take early, ideally before you start applying for internships. Enjoyed the first half of the module more than the second half because Prof Ma appeared more prepared for lectures than Prof Zimmermann, though I think Prof Zimmermann is more experienced. Assignments were pretty “hands-on”, I think? It seems like something that can be applied to real life programming, so it
