The story of Joseph

Going through the story of joseph on sundays now...

Just a quick thought - in the days of joseph, people were plagued by famine, as they had no control over nature... These days, technology has advanced to the point that we are able to produce the food we need almost without being affected by the problems posed by nature, yet we are plagued by problems that seem equally beyond our control - our modern day famines take the form of economic crises.

Are we any better off than in joseph's time?


And they were playing songs from "Joseph and the amazing technicolour dream coat" after the service... Miss the songs! Does anyone have it??

Midway through term - that was fast!

Wow, and half the term just sped by like that!

Just survived my first wave of heavy days... Had a full day on tuesday - spent 9 hours at the cavendish, 9am to 6pm, for 3 lectures, an example class, and a supervision. Another supervision today which ended with another natsci cookout - the kind organised by second years to welcome first years.

Working backwards, AFF on sunday was good... ah, cant really remember much before that...

Half the term's been quite good.... meeting people who would help me understand work... A lot of catching up to do, but there's hope that it'll go well...

Next two days will be busy too - preparing for temasek's dinner and discussion tmr, computational project and gotta come back and prepare food for cg on friday, then there's reading up for literature review...

CG: working through the book of matthew now, beginning from the beattitudes, and working through the parables...

The story of joseph on sundays, and romans at focus...

Term might go well, please keep praying for me...

Oooo... Ratatouille - Behind the scenes.

The science behind chopping scenes in Raratoullie.

Stumbled on it while searching for ways to handle scalar fields for my computing project.

Update

Ok a quick update on what's been going on...

Been busy... in part with this, as well as school work, which is been piling...

But before i forget, Houseparty's confirmed to be held on 3-6 December (Monday til Thursday), so daddy, can plan your trip around this date. Also, cant find my usb stick when i arraived; and realised that i dont have vit c with me, have been fluish for a while... can help me bring these items from home? Thanks.

Happenings:
It's been two weeks and a bit into school... trying to keep up with work. Had a few cookouts so far - 1 natsci, 1 with cumsa kids.

And had lunch at Lye Chong's place (a grad student at HH) on Sunday... He has a year old son, and he had a church friend from singapore visiting cambridge, whom he invited for lunch too...
Had children's christian music playing in the house, and other children's items like books and toys strewn around the house, bringing back to me recollections of the atmosphere during my own childhood... Met his son a couple of times before, but after playing with him during lunch last sunday, I'm beginning to feel a little attachment with him... oh no...

This term's snack is prob going to be Danish Butter Cookies... They are on offer (99 pences) at sainsburrys for the regular tin, it's usual price is 1.50 pounds. I think it's rather cheap... dunno how much they cost back in sg... Anyhow, it's better than 4 bars of basics chocolate, which i havent touched since i arrived.

And this term's meal would be chicken rice... very cheap and hassle free - usually marinate 3 chicken wings a meal (a pack of around 8 basics chicken wings cost under 1.50 pounds, so 3 chicken wings works out to 50p), then throw it in the rice cooker (with lettuce sometimes), and forget about it til i'm hungry... if i'm cooking with lettuce, would usually take it out afte about 10 mins. Blogging over a bowl of chicken rice now :P

Also i'm doing laundry manually this year, since they raised the price of using the washing machine to 1.40 pounds... It's quite therapeutic actually, good to do after getting bored with work.

Ok, a rather abrupt end to a disjoint post... it's two AM in the morning, and tomorrow's going to be a hactic day, with 5 hours at the cavendish... later...

Physics Forums

Just found this:

might be a solution...

g ~ π2

Here's the answer to an interesting observation I made a while back.

Turns out that there is indeed an explanation for the apparent coincidence.

Catching up on blogging after a long haitus

Wrapped up my attachment on friday with the End of Attachment Presentation...

The 9 weeks on the job was colossally enriching!

Wrote an entire package in Matlab, concorting meshing algorithms, solving underlying problems mathematically, and implementing their solutions computationally. Learned to handle geometric models with nodes, lines, surfaces and elements.

Also read up on the topic "Computations with discrete forms". Some terms used in the topic for future search reference: Barycentric Coordinates, Whitney Forms, Hodge Star, deRham Complex - chain & cochain complexes, a primal and its dual, (discrete) forms.
Set of two Caltech lecture ppts on the topic: Calculus on Meshes 1, Calculus on Meshes 2

Met another intern studying at Stanford who is interested in exactly the same physics as me - QFT and it's likes. Managed to learn up some solid state physics together. It's such a joy to have just one other person with the same mind. Having one other person to affirm concepts at crucial points in a topic can help accelerate the learning process very substancially, something which my situation in Cambridge has left me sorely deficient. Hope it gets better next year.

Today
Spent Saturday, the day after my internship ended, spring cleaning my computer.

Sorted out the documents and programs I have, as well as my music files... itunes duplicates my music each time it reindexes them when i reformat the computer, and it's quite irritating for a song to be played 4 times in a row.

Installed some programing utilities during this round of laptop spring cleaning:
Created a seperate account to code in so that the files can be managed more neatly,
and quite interested in the recent developments at google, in particular the introduction of Google Code, the release of Google Web Toolkit, and Google Calander API. Can now port over the reliability of the google calander to php webpages!

Also keeping an eye out on the developments of Octave, the open source equiv of Matlab. Looks like there is quite a concerted effort in making it run as well as Matlab. Waiting for the version 3 release. Found an editor, SciTE that works for quite a good number of languages - php and matlab among them. And re-exploring java programming along with the previously mentioned gwt.

Looking to next year
Also bearing in mind the course requirements for next year, including the computational component in fortran, as well as all the other topics. Need to translate what I have into gains on my grades! Really hope to find next year's course engaging and its requirements enjoyable to fulfill. Cant see how it's going to come about given the previous two years... Still, hope dies hard.

Optimisation

Just implemented an optimisation code to minimise the lengths of the lines joining the points...

And here's my optimised star!

Some nice images from my internship

Just finished writing a 2D meshing algorithm in Matlab. Here are some visually appealing results generated from the code:

Reckon that these images look rather mundane to most people.

Beauty indeed lies in the eye of the beholder :)

Update

ok, here's an update of hols...

been quite busy, with a day job, and trying to keep in touch with everyone in the evenings and weekends, as well as catching up on last year's work while the luxury of home lasts... Hence the lack of blogging.

have uploaded some pics of eastern europe, but it's still not very presentable yet, need captioning, or at least sort them out in some kind of logical order. but have yet to find the time to do all of those.

upcoming happenings include visiting SAJC on 15 Aug 1430 to help with the UK talk... Anyone interested to come, please call!

work's been good... picking up loads. worked on my linux box remotely from work for a while, installing the simulation program, and running some simulations on it. now utilising programs like matlab, gid, to try to set the problem up - generating the geometry of the problem, as well as the finite element meshing. Supervisor's also really nice, working together on a kinda equal footing to solve problems. Have been communicating with him in chinese, and i'm finding myself thinking in chinese whenever i subconsciously run through the problems! :S like "de2 dao4 le4 zhou1 wei2 de4 nodes yi3 hou4 jiu4 ke2 yi3 qiu2 geometry de4 ping2 jun1" and "magnetisation hui4 chong2 zheng4 de4 bian4 dao4 fu4 de4".

managed to meet up with many people this holiday too!
  • Sec sch classmates at Jonathan's send off just days after I returned - alvin, daniel, shawn foo were there.
  • JC classmates, on a couple of occasions. Jimmy, Chintee, Izz, hanes. Board gamed, and had prata at bukit timah.
  • Scouts, on a few occasions too. Shamir, varun, tsang, for a board gaming session; plus juniors Wilson, yiming, gerald, austin, sherman, during shamir's send off.
  • Everyone in church! during the r-age 10th anniversary the day after touch down.
  • CF people - daniel, lish, ben, lauren, charles, during the bbq and a dinner.
Also walked the length of orchard after confluence, to see the ferris wheel, and popped by the newly refurbished museum. They have quite an interesting exhibit on singapore food, complete with a sample of the smells! Watched the simpsons too! but wasnt very good. As jon puts it, it has too much storyline for a simpsons cartoon.

so on the whole, hols have so far been quite fulfilling. would be quite busy still, making the most of the time in sg, as well as accomplishing other things like temasek website and updating links on this blog. blogging might also continue to be sparse.

signing off...

Fedora for the home PC!

Just installed linux on my pc at home. Thanks to HCH for helping me with the installation and orientating me to the interface. Intending to use it mainly as a server for me to back my data up.

Gotta equip it with and test out the following:
LAMP - Linux, Apache, MySQL, PHP, to provide the web serving capabilities, mainly to provide nice interfaces for the data I'd be backing up (e.g gallery2 for pictures)...

Ftp Server (filezilla maybe) - to upload my data for backing up.

Telnet perhaps, so that I can execute commands on the computer remotely.

The kind of data I intend to back up fall mainly under into the following categories:
1) Pictures + clips.
2) Music.
3) Movies + games.
4) other files, like word/excel/pdf documents.
5) Installers - I'll back up the installation files of all the programs that I find reliable on my home computer, so that whenever I reformat my computer, I'll have a one-stop location to download the installers I need. Gotta make a list of programs that serve well. Currently looking for a gif animator, and it's been quite difficult to find a good one, I need flash! Also, just found a good Audio File Converter Program, Switch and wavepad.

Have been using them to work on the webpages I'm mastering... Which has been occupying me since I returned.

CCCF website: changed the banner, added a little icon, changed the music, and now I'm hoping to create a little flash applet to synchronize changing pictures with the music. Did a little javascripting on it.

Temasek website: Touched up the look of the 'latest articles' and 'latest comments' panels, and hoping to touch up on the banner, and the aesthetics of the page in general. Did some MySQLing on it.

Back!

Just returned in the morning after 2 weeks of traveling... loads to consolidate - pictures, the trips, my belongings, my work, the internship.

Airport experience was interesting. Checked in rather late, though still within the stipulated time, but was held back by immigration due to an increased alert level (perhaps because of the bomb scare in London). Queued for immigration till past the flight timing of 12, and was given an "advance to go card" soon after 12pm.

Thankfully was able to check in my slightly over the weight limit baggage, perhaps because the airport staff was concerned with the above stated more pressing matters. Upon check in, we were instructed to go straight through security and immigration, and not to loiter in the shops.

K, lots to do now. Trip pics to be up soon (hopefully).

sigh... 2-2 ;(

in austria now..

just found out my result... not good at all... but guess that means there´s more room for improvement next year... tough year this one was... :(

hope i can still do theoretical physics... ok time´s running out...

Saturday, June 16, 2007

Ok, this is it...

moving the remaining life support systems out of my room soon - my laptop, fan, bedsheets. Will be down to my bare traveling necessities.

wont be able to access the internet so frequently til i reach home, but there should be internet cafes along the way.

Departing tmr morning at 3, and my itinerary is as previously posted.

Will be contactable on my sg number.

Also, just realized that I'll be exceeding the weight limit by a lot (my luggage weighs 35 kg, and that's not counting the laptop, and traveling baggage), from all the goodies I'm carrying home. Daddy, can help me ask SIA for extra baggage allowance? thanks.

Back from portugal, with a bottle of Port!!!




Just returned from Portugal this morning - visited Porto, Lisbon & Sintra.

Quite a packed trip... felt like we accomplished a lot in the short span of 4 days.

The highlight was perhaps visiting a brewery in Porto. Sandeman, the brewery name was.

Appreciated how Port is actually grape juice that is partially fermented (as compared with wine which is fully fermented grape juice), to produce alcohol yet leaving some sugar to give it the sweet taste. Bought a bottle, for everyone back home to try! So prepare to get drunk :P

Also learnt that Port wine is named after the city of Porto, which is so named because it's a port. And a port is a gateway or entrance.


Will be packing up, and leaving in the next few days for Eastern Europe.

Also, got the reply from astar, and will be doing an internship with them again over summer. Quite looking forward to that...

yup, not too long now, will be home in another 2 weeks! see everyone soon...

Leaving for Portugal in a while

Consuming simple ovened dinner and leaving for portugal in the wee hours of the morning. Will be gone for 3 days, back for 3 days, gone for 12 days, back for one night, and finally departing for home!

Here are my itineraries for Portugal and Eastern Europe.


Was reading through my post exam posts last year. This time last year, Chai Seng gugu was here! Took them round cambridge, and drove up to kings lynn.

Went to London with ken, lionel and serene for a few days the following week, packed up and left for Italy on the 21st, learned of my result on the 24th, and was home on the 29th. Coming full circle this time round, with London replaced by Portugal, and Italy by Eastern Europe.


And... My room looks like a warzone!

Consolidation

Have been done with exams for close to a week now... And have been quite productive since then...

Sorting out stuff, packing my room, looking into travel arrangements, buying goodies to bring home, just consolidating my two years in Cambridge. I'm quite glad to have the time to do these leisurely...

Lets see, since the exams ended on friday morning, i've...

Friday, 1 Jun:
slacked friday afternoon away, recuperating.
Crashed garang sheep, helped them cook. visited joel's place after cg...

Saturday, 2 Jun:
Slept til late. went for brunch, think i slacked the afternoon away, prob listening to bbc and cbs podcasts. Had dinner with keng rui and irene. Went to Shawn's place to watch "Troy". Daniel was there too... "War is young man dieing, and old man talking". Stayed til 1.30 am.

Sunday, 3 Jun:
Brunch at 9 with joel, su-ann, celene. Made french toasts and pancakes.
Church, lunch, didnt really do much the afternoon. Dinner with keng rui.

Monday, 4 Jun:
settled errands, returned the library books, booked formal hall tickets, practiced a little for cf worship. Went to town to leave guit with WS, did some banking. was listening to bbc podcasts. Went to help with the food prep for cf at 1630, got some boxes from sains, had worship practice at 1800. CF til late, went to play com games at daniel's place after til around 2am.

Tuesday, 5 Jun:
Sorted out travel arrangements, went to print documents (hostel bookings, maps) at the CMS... Attended focus, went to visit aloysius to do maths. Thought of traveling on a cheaper airline here next year, emirates, say. And thought of going to Greece, Cyprus and Turkey next Christmas, and France, Germany and Belgium next Easter.

Wednesday, 6 Jun:
Did some packing up, bought goodies to bring home, found out about national express tickets, going to buy them soon. Suddenly felt like i was spending a lot of money. Now trying to keep track of all my expenditure.

For the goodies,


The big boxes of cookies were 2 for 5 pounds. (5.00 x 2)
Short cake was 0.79. (0.79 x 2)
Milk chocolate butter, the one on the left was 2 for 2 pounds (2.00 x 2)
Shortbread was 2 for 3.50, i think. (3.50 x 1)
McVites Boasters was 2 for 0.99. Bought 6. (0.99 x 3)

Spent 22.05 on goodies to bring home. You guys back home, please tell me if the bargains were good and if i should buy more of them back. But my luggage is already half full with the food. Going to be hard to squeeze more in it.

For the packing, thinking of getting a plastic box for my "lever arch files". They cost 10.99 pounds. Need to get more boxes too. And transport to caius will cost another 11 pounds.

Then there's money to be changed, and tickets to be bought.

Kinda looking forward to going back in summer to work, and make a little living for myself. Also thinking of all the other things i need to do in summer - go through the materials for this year and next, gre's, tuition, playing - all the movies to catch, and showing sam what i've learned this year :D

Towards the near future:

Tomorrow:
Continue with all the preparation and packing, and going for a briefing for a demonstration i'll be going for on friday.

Friday:
Taking part in a school visit to do some science demonstration. will be interesting, and will occupy my mornings and afternoons.

Saturday:
Preparing for the trip on sunday. Make sure all the errands are run.

Sunday to Tuesday:
Will be in Portugal.

Wednessday to Saturday:
Will be back in cam, attending garden parties, and packing up for good.

Sunday, 17 to Thursday, 28:
Will be in Eastern Europe.

Thursday, 28:
Arriving back in cam.

Friday, 29:
Departing for Singapre!!!

Saturday, 30:
Will be sleeping on my bed for the first time in 9 months!

Wow! that was an entire month in one post!
