The hardest logic puzzle ever

Wow this is seriously the most crazy logic puzzle ever. If you can solve it on your own, you are really pretty damn amazing.
I'm reading the solution and I'm already taking ages to even understand it lol.

WARNING - this is really mindf-k to the max! Don't embark on it if you don't want to kill 213987 of your brain cells.


The Puzzle:There are 3 people, A, B and C. One of them always tells the truth, one of them always lies, and one of them always randomly decides to tell the truth or lie.
Your task is to ask 3 yes-no questions, each question has to be directed to only one person, and figure out who is which.

Some clarifications:
- They know each other's roles
- You can ask one person more than one question (e.g. all 3 questions can be directed at A)
Whether the Random person speaks truly or not should be thought of as depending on the flip of a coin hidden in his brain: if the coin comes down heads, he speaks truly; if tails, falsely.
- Your question has to have a yes-no answer. (E.g. no 'maybes', paradoxes, etc)






If you solve it let me know what your 3 questions are! :D Contact me for any further clarifications too. 


(DONT GOOGLE FOR THE ANSWER TRY TO SOLVE IT YOURSELF IT'S FUN FUN FUN FUN )

Night Cycling!

Yesterday I went for my first ever night cycling trip with the Arts OG! Seriously love the enthusiasm of the freshies to keep organizing these things.. hope it never dies out! hehe.

The co-organizer Hysen had everything planned out:

‎8pm – 10pm Dinner/Renting of bicyles10pm – 12mn Part 1 of Cycling trip12mn – 1am Supper at East Coast1am – 2.30am Part 2 of Cycling trip2.30am – 4.30am HTHT session4.30am – 6am Part 3 of Cycling trip6am – 7am Breakfast at Macdonald7am – 8am Last leg back to Changi Village 

Wa can be any more meticulous anot! Got schedule somemore! haha.

The general plan was
Part 1 - Cycle from Changi Village to East Coast Park Lagoon for supper
Part 2 - Cycle from ECP to Marina Barrage to chill
Part 3 - Cycle from Marina Barrage back to ECP Macs for breakfast
Part 4 - Cycle back from ECP to Changi Village

The first part was loooong there's this super long stretch of road that seems to run parallel with some airport runway so we kept seeing planes takeoff as we cycled down that long road. I was still with the front pack at this point, and the others were falling behind it seemed, cycling very slowly!
And chipang was such a noob omg whining like a girl! Kept saying tired etc. The freshies kept making fun of him haha was quite funny. 'Eh guards one why lidat ah' (he was from Guards)


So we sat at Lagoon and me simin grace and keryu shared a plate of Roti John while we all just... talked abt random stuff. It was mostly GS and CP talking to the other PJC freshies about PJC.

Anyway, we began Part 2 shortly after this, in spite of CP's incessant complaints and suggestion to just chill at the beach.

We headed towards Marina Barrage, including a detour into this gays carpark where apparently gays go to pick up other gays and they'll make out in the bushes. Didn't see anything interesting though.

Along the way, because of alot of people complaining that they were tired and etcetc we ended up heading to Singapore Flyer instead of all the way to Marina Barrage. However, we still had to clear this crazy :

MONSTER STAIRCASE. It is about twice what is shown in this picture

Our only route across was to go up this staircase which led to a long flyover which connects directly to Singapore Flyer area. So we had to carry our bikes up this stupid staircase before we could take that flyover.
Oh but the flyover was fun though, it had one of the longest slightly steep downslopes that we could glide down.. AND halfway through it starts to bend so you really have to control your brakes and steer your bike down.. but of course you don't want to brake too much if not it won't be fun anymore! haha. adrenaline rush max


We reached the Flyer and sat near the F1 pitstop area and just talked random stuff for abit while resting... I entered the girl's toilet there! Hahaha. Cos i went with simin and baoyue and the guys toilet was closed so we just all took the girl's toilet. It was like 3-4 AM anyway so sure nobody.

And after awhile we decided to head back to ECP macs, and had to clear that bloody staircase again but this time downwards la. But still have to carry bike.

Breakfast was extremely satisfying, relished my customary Big Breakfast (just about the only thing I eat from the Macs breakfast menu), and then it was the long return leg!!

Ok I don't know why for this leg me and simin were all the way at the back now. It's like the people who were previously too tired to keep up with us were now too desperate to get back so they chiong in front. Then I just stayed behind to cycle with Simin la, more fun ma :)

Was super shack can! The last leg back. Our butts hurt like mad from the seat and our thighs were on the verge of cramping also. Had to keep motivating each other to keep going haha. ALMOST THERE ALREADY.

When we finally caught sight of Changi Village.. OMG SHIOK. haha. the feeling of knowing you have reached the destination is awesome.


All in all it was a great experience, but I don't know if I'll want to do it again haha. Very tiring! And I think the freshies just bring a real nice energy that I like to hang around, unlike around certain other seniors... (shh)
It was also great to cycle and chat with simin most of the time, damn fun man! Though my attempt at introducing some philosophical stuff from PH1102E totally failed because I forgot and mixed up the arguments/analogies  xD Was great company nonetheless :)

Though of course I wish certain other people were there, like sang, joann, CANDICE, si en, munch. My usual hangout buddies! Eh and it's not my fault that they're all girls k, the guys are all phantom one what to do. Like wilbur, gary (like almost never see him at all whole year)... noone else sia. PHANTOMS.

Ok this is a very boring post but I just wanted to pen it down so I can read it in the future for memory's sake :)
BYE

P.S. Blogger's new look sucks. Gimme back the old one!

The IPPT

For the benefit of the non-Singaporeans reading this, the Individual Physical Proficiency Test (IPPT) is an annual fitness test that all Singaporean males (after they have completed their mandatory 2 years in army service) have to clear (if not, they have to go for Remedial Training which is a 10 week bi-weekly course)

There are 5 stations in total - 
Standing Broad Jump - Start with feet apart, stationary, and jump as far forward as you can.
Situps - Bent knee sit-ups, as many as possible in 1 minute
Chinups - Grab a bar and pull yourself up as many times as you can
Shuttle Run - 4 x 10metre sprints back and forth, testing agility. Complete as fast as possible.
2.4 KM Run - Run 2.4KM in the shortest time possible.

So today I went to attempt my IPPT. I had NOT prepared in any way whatsoever besides doing pullups maybe 2-3 times a week. I was just going to get a gauge of my standard so I know what/how to train.

Naturally, I was extremely nervous/scared/apprehensive from the start of the day.

4.15PM - Arrived at Maju Camp for my IPPT, but was told by the guard that they were only letting us in at 4.30PM. (The IPPT was scheduled to start at 5PM)

Went over to sit at some chairs outside of camp, and spent the next 15 minutes swatting mosquitoes which tried to suck my succulent legs and controlling my pounding heart.

4.28PM - The guard came out and told us that we could go in. They actually updated their 'entry' systems! They actually use handheld scanners to scan your ICs now! Nice, high tech. I wonder whose USMS that was. Sure win alot of money.

4.32PM - Reached the Fitness Corner, and had no idea where to go as it was my first time taking my IPPT there. Walked around aimlessly, looking at other people for guidance. Totally committing pluralistic ignorance.
(shamelessly showing off my Psych knowledge) (actually now that I've checked online sources it seems entirely different from what my Psych Textbook taught me wtf. fail textbook)

4.45PM - A PTI (Physical Training Instructor) finally opens up the InPro (in-processing) booth where we go and get our number tags.

5PM - I had already gotten my number tags and was sitting with the many others who were waiting around impatiently for the IPPT to commence. I could feel a tiny lump in my throat now.

Seriously the waiting is the worst part, it just makes you even more nervous and even more scared.

I remember reading this particular scene in one of the Hannibal Lector series (awesome stuff btw) where the psychotic Dr Lector had his prisoner chained up, and let him know that he was going to cut off his toes daily, one at a time, then his fingers, then his limbs, etc.
(Being extremely sadistic he also replenished the fluids and blood lost via some saline drip or something to keep the person alive)

In the book it was clear that it was not so much of the physical pain that was wearing the prisoner down, but more of the mental torture of knowing the extreme agony that was going to come each day. The wait was the worst part of it all, and could drive a person crazy.

Anyway, random digression aside, the wait was finally over when the PTI announced the start of the IPPT session.

After 5PM -
I had a clear strategy for the sequence of stations to attempt mapped out - I was going to start with the pull-ups, then the shuttle run, then standing broad jump (SBJ), then situps.
I wanted pullups first because it was the only upper body one, and won't affect the rest. Shuttle run was next because I wanted some adequate rest time after that (sprinting is tiring) and the 2.4KM run at the end. Situps tend to cause some kind of strain in your inner thighs (hard to explain why) so SBJ had to be first.


Chin-ups /Pull-ups

I stepped up boldly to be one of the first few to attempt the station. I was pretty confident of passing this, as during my practices I always managed 6. My aim was 8 today though. (6 is to pass, 8 for silver)

I watched some chubby guy in front of me struggle to do 2 and kept my chin up. (wow pun unintended) 'I'll beat him easily!'

Then it was my turn.

I stepped forward and put my electronic number tag into the tagholder, and stepped up to hang on the bar before starting.

Go! 1, 2...

Oh wtf, the bar has almost no grip. My fingers are slipping. Readjust.

3, 4, 5.

Why don't they invest in some kind of better grip bars! Omg don't slip and fall don't slip and fall.

6...

(Yes, I did it. I passed)

7...
One more. One more alan.

8!!

Bells went off in my head as I gracefully jumped down from the bar, and restrained the urge to do a celebratory dance at my first completed station of IPPT. I strode confidently away from the station, imagining envious eyes looking at me walk away (there probably weren't any in actual fact)


Shuttle Run
Never really had a problem with this station, besides the odd mishap in JC1 (just Ctrl+F 'shuttle run', it's from the very first post) , but it's one station which you can't practice on your own so I did feel abit nervous about it. Also, the JC1 incident left a lingering phobia in my mind.

As I was queuing up, I saw this slightly plump guy do some dramatic somersault when he tripped and fell mid-shuttle run and he rolled up and continued running to finish it up. Super drama. Like kungfu movie. (he failed anyway)

Then it was my turn. I strode up and put my tag into the holder again for the electronic reader to register it.
There's a way to kinda cheat for this, you just stand slightly further back (like one step away) and start running from there. There seems to be some sort of delay from when the timer starts and when you go through the gantry.

Anyway, on my first time forward, I sprinted too fast and neglected to slow down on the turn, and slid abit and the turn wasn't very fluid. Damn.

Made the mental note to slow down slightly on the turn back, and completed the other 2 turns smoothly.

Ran through the gantry - turned around and looked at the scoreboard thing - 10.00seconds. 5 points! (A)
lolololol. Even with the little skid at the start I still managed an A. Oh well.

Chest full of pride, I walked towards the next station.


Standing Broad Jump (SBJ)
Another station which you can't really practice on your own, but I've always been alright with it (and even set some kind of record when I leapt a bewildering 261cm in Sec2, no idea how I did that), managing a decent score.

Saw a few fat dudes (like really fat kind, those that take up 2 seats on the bus/MRT kind) attempt the SBJ in front of me who almost broke the machine when they landed.

HAHA ok I shan't be so bad. But it was really funny in a mean way. Like see them cannonball forward like 1 metre or something.

Then I saw this spectacled guy in front of me who did his jump and when he landed, his spectacles flew off, and I stifled a giggle. Hahahhaa super funny. How can his spectacles fly off? sucha noob.

So came my turn. I stepped up, looked forward, did my customary swinging of arms, and leapt forward with all my might.

F MY SPECTACLES FLEW OFF.

I quickly fumbled to grab my specs and put it on again and glanced at the score. Whew, at least it's a decent score, 239cm (4 points).

I wasn't satisfied so I tried again... AND MY SPECTACLES FLEW OFF AGAIN.

Why ah.

Anyway, I only managed a 239cm again, sigh. Oh well, 4 points is good enough. On to the last station (before the 2.4KM run!)


Sit ups
This is my pet event.
Back when I was in early secondary school years, I had some obsession for training and mastering situps for some reason, so I did them really regularly.

On my bed, I actually managed a whopping 120 in a minute. Yes, 120. That's 2 per second. It's because the bed is quite bouncy so you can bounce up very quickly.. but it isn't very easy still! Try it!

In Sec2 (seems to be my peak) I did 74 in a minute on the normal mat, which was my best ever. After that was probably 60ish.

(Eh sorry la, let me boast abit, I don't have much physical achievements to boast about LOL)

Anyway, the 5 points(A) requirement was 40 in a minute, which is quite easy in my opinion. I think most people without a huge tummy should be able to get it?
And I really think my training from secondary school has developed fast twitch muscles in my abs, so I can do this really well. But if you ask me to do like 100 situps maybe I can't (more reliant on slow twitch since it's endurance)

So I just raced my way to 30 within 20+ seconds, and rested for 10 seconds, then did another 10 to hit 40, and just got off the platform. I mean, why try harder, just get 5 points can already! Must conserve energy for 2.4KM run!

(Oh when I sat up to remove my tag from the reader, it registered as one more situp. Haha. So i got 41)

2.4KM run

The run was held at a nearby indoor multi-storey carpark (MSC). I have heard from friends that the indoor nature of the MSC made the run additionally difficult, as there is little ventilation and hence it can get hard to breathe. :S Oh well.

 When I reached there there was already a decent sized crowd there, so before I could complete my series of stretching the PTI decided to begins his briefing so I had to cut it short. Not that it would really matter.

And just to foreshadow what you are going to read, I set a personal record in this run.

So anyway, the PTI told us about the route, run 6 rounds around the MSC, how the electronic system worked, yada yada. Ok, time to start the run.

We were dispatched in waves, and I was the 3rd wave. Ok no problem. On your marks.. jogging on the spot.. 3 , 2, 1 GO!

With my brilliant mathematics, I had already calculated this. To get a passing timing of 12:20, I need to run approx 2 minutes per round. As long as each round is under 2 minutes or around 2 minutes, I'm in good time.
Generally, I'll want my first 3 rounds to be under 2 minutes, since it's natural tendency to slow down from fatigue in the last 3 rounds, so they can be 2 minutes+.

Round 1
Got off to a quick start.
huff puff. I can do this. catch up with all the flabby people!

Passed a few flabby unfit looking people. Yes! I'm winning!

When I passed the line, I saw my timing for Round 1 - 1:45. I'm in good time! Well done!

Round 2
Ok this is getting tiring.
I'm starting to pant. I'm regulating my breathing heavily to match my footsteps.

Where is all the oxygen? My lungs are starting to catch fire. It's like I'm sucking in air but my lungs don't feel better. My steps become smaller. My pace gets slower.

Round 3
The fire in my lungs is raging.
I'm sucking in air as much as possible, but I didn't feel any better.

Normally, round 3-4 is where you are finally warmed up and you are just settling into the pace of running and shouldn't be that bad.

But this time, I never got to 'settle in' to the pace. It just got worse and worse as I continued the lap. My steps became much smaller, and people were passing me left and right.

Where is the oxygen? Gasp.

When I crossed the line, I saw the timing - 6:22. Shit.

Round 4
The burning fire in me was dancing around my lungs, and people in front of me were stopping to walk, and the peer pressure got to me and the mathematics of it all was clear-
If I took 6:22 to run the first 3 rounds, assuming I run at the same pace (I would probably slow down), I was going to complete it in 12:44. Which is a fail timing. Literally. There's no point continuing anymore.

And thus, for the first time in my life in 2 years, I started walking in a 2.4KM run . :(

Suddenly, the sagely advice of why you should never ever start walking in a 2.4KM hit me like a truck. Almost within 10 seconds of my commencement of walking, I developed a very painful stitch in my stomach

OUCHH. OMG.

Not only that, my legs began to feel crampy, and I kept trying to stretch while walking to shake the cramp off and get rid of the stitch.
I tried to jog abit at the end of this lap to the next.

Round 5
The stitch was full blown now. It was like there was an alien in my side, trying to claw it's way out. It was all but clear that there was no way I would be able to force myself to continue jogging the rest of the way 'just to train' with this pain in my side.

I did the known solution - stretching my side as much as possible while taking deep breaths to let the intake of oxygen cure the stitch.

But wait, guess what? Right, there's no oxygen.

So my pathetic walk continued, only jogging quickly forward when some fat dudes started to approach me from behind - my pride was too big to let some obese fellow who eats McDonalds for all 3 meals beat me.

Round 6
Pretty much the same, me struggling with my stitch, and only running forward to avoid the fat people behind me. Some flabby ones DID pass me, but I was already in the 'cbf zone'.

Completed the final round by jogging through the gantry, and lol-ed at my timing.

17:14

HAHA WTF.

I said at the start that I set a record this time round. Yup, that's the slowest I've ever ever ran in my life. But yea you can't consider it running when I walked half of it. But still, that is just hilariously bad.

The final results



Sigh. Gotta go running now. Have to get used to the burning lungs feeling, and hopefully I can overcome the oxygen-deprived indoor carpark of Maju Camp! Really harder to breathe than usual! But maybe it's because I did not train at all lulz.


That's all folks.
