A Pinch of My Life

2011-10-20T17:51:00.002+08:00

I'm fine... wait... that's a lie

I'm far from fine... I'M SUPER! TOTALLY JOYFUL AND CONTENTED!

Nothing beats going to sleep each night extremely exhausted from a day packed full with events, waking up still tired but ever so happy and thankful that I'm living my life to the fullest, doing the job I love, and having all this opportunities to serve God and make a difference in people's life.

To God be the Glory!

1 month into my first job

2011-09-15T20:05:00.001+08:00

It's a month into my first job as an IT Analyst. Gosh.. That title sounds so chim, I don't even know how does "analyst" fit into what I am doing so far. Haven't been "analyzing" anything. That -- at least I'm sure of.

Anyway, today is the most exciting day so far as my job scope and responsibility is starting to materialize and become clearer to me. Suddenly, I see more and more of what is expected of me, and where I can actually contribute.

First, there was a meeting called by the project manager to clear up on the technical stuff for a project I'm in charge of, which I am taking over from a colleague who's leaving. Then, I went to 2 datacenters to install a server each. Gosh, the way servers are designed and all, makes it so efficient and convenient for us administrators. Little features and gadgets here and there which one wouldn't realize are a necessity until one has seen and used it. It's almost like Apple products... But enterprise class!

Just a picture of the server I installed. Didn't get to take a photo of it mounted and running in the datacenter however, as no cameras are allowed there.

Btw, datacenters are horribly noisy and cold places. Even want to talk also must shout. Not a place anyone would like to be. The moment a server is installed and set up to the bare minimum, which typically takes less than an hour, we normally then proceed to our comfy cubicles (with a mug of hot coffee, of course... Maybe I'll post a pic of my cubicle In some future post more related to that) and remotely do the rest of the installing and monitoring from there. Ever seen one of those remote controlled toy cars that's has a camera attached to it to show you where you're going on the remote itself? Well, this is somewhat like a grown up version of it. With almost everything (except the physical location of the server itself, of course) able to be controlled from anywhere in the world, servers are very expensive toys indeed. :-)

Be Thou My Vision

2011-03-20T04:21:00.003+08:00

FYP is so stressful, I can't fall asleep at night.

Sometimes, I just feel so depressed, and just don't see how I'm going to be able to pass my FYP at all, with the thesis due in 2 weeks time, and my project is not quite completed yet...

And then I was reminded, that I should shift my vision to God and know that even the fact that I'm alive today is by His grace and mercy. Once He's out of our vision, life will be a ship in a storm, no bearings, not destination, and no hope...

This so hard to start from scratch...

2011-02-06T23:45:00.000+08:00

My social networking site is still an empty eclipse project. So much knowledge, so much readings, but actually putting teeth to stone is just so difficult. So many choices, and not having a good estimate of the cost of committing to each one is very traumatizing.

One of life's lessons

2010-12-12T22:46:00.000+08:00

Sometimes, knowing the truth can make one sad...

But it's always so encouraging to know that humans have a remarkable ability to recover very quickly.

It won't be long before one is on his feet again.

2010-12-07T16:37:00.002+08:00

Last Sunday, we (Gail and myself) went to watch Tangled with Boss and WMWMWM. It was so cute, and so happy... something expected from Disney!

Actually, I have to thank my MNO1001 lecturer and teaching team for such a rewarding experience. We had to make a video, and our video will be screened ala the oscar awards thing. And both nominees and winners get a prize.

My group's video was nominated, and the gift was very pleasant indeed. That was already more than a year ago...

Fast-forward to last Sunday, we decided to realize the value of the voucher with Disney's 50^th animation. With so much hype about it, and being the biggest budget animation to date, plus the cute characters, we were all quite excited.

Actually, the voucher was valued at $7.50, but the show on Sunday was supposed to be $9.50. Nevertheless, when I claimed the vouchers, I managed to get 4 tickets without needing to pay a single cent! Guess the vouchers actually have some protection against inflation too; each voucher guaranteeing that you'll get a FREE movie as long as it's within the expiry date and it's not a special screening. A very nice touch from Shaw theatres, definitely an extra reason for me to go back.

So much about my vouchers... Tangled is actually a very nice little animation. With lots of songs with cute lyrics that rhyme so well they don't feel lame (they actually are quite a bit lame, refer to blog title for example, but you don't feel it when watching the film).

The amount of effort they put into the animation is definitely commendable, but then again, with pretty good plot, and nice graphics, the soundtrack somehow pales in comparison to that of "How to Train Your Dragon". Quite disappointing, though I must say the latter offers a bigger room for composition, with its Irish or Norse setting and having so much legends and mythology behind vikings and all...

Maybe it's just not easy to make music for a world that's purely imagined, like what Disney always strive to achieve, the imaginary Disneyland. Music comes with culture, history, and civilisations, and it's not easy to make good, deep music for something that lacks so much depth. It's quite commendable that the music is at least pretty good, and the lyrics are entertaining.

Ultimately, good animation, makes one feel rather happy, though if you are in for the depth, and the keep-wanting-to-rewind-and-play-just-to-look-at-it-and-hear-it-again "feeling" that I can't describe, I'll still say "How to Train Your Dragon" left much more impact in me.

EE3208 Speaker Design

2010-05-10T20:50:00.000+08:00

I was stuck designing my circuit for the speaker for almost the past day or so. I wanted to simulate it with SPICE, so I used the free LTspice to simulate it.

Finding the SPICE model for the LM386 power amp wasn't hard, but wiring it up to work took me almost a day.

Later, I found my mistake.

Anyway, I needed to output 8kHz, 8bit, Mono Audio using the DAC0832. I know it's rather primitive, but this is the requirements of that project.

I read again and again through the DAC0832 user manual, but I just can't seem to understand what it's trying to say. Should I feedback, or should I not feedback. This is so confusing.

At the end, I decided to do a simple circuit, using a resistor to ground to convert the current out from the DAC0832 into a voltage, varying the resistor to get the desired output volume.

What a project.

Here's the LTspice schematic and the LM386 model. You'll have to put the model into C:\Program Files\LTC\LTspiceIV\lib\sym\Opamps to use it as a component.

Haha, enjoy!

Rain, and the joy it brings

2010-03-11T01:36:00.000+08:00

The rain came this morning, had such a wonderful sleep. And even now, at night, even it didn't rain yet, the weather is already cool and comfy. I'm all prepared to snuggle into my bed and go to sleep.

But before that... Something that rang in my ear, just like that... It just came to me, and I decided to youtube it.

This is quite an unpopular song, very hard to find a nice version that appeals to me emotionally, the music, I mean. In fact, I think this is one of the only 2 versions on youtube, and the other version is from the 70s, and didn't sound very nice...

But it goes against the way I am, to put my human nature down,
And let the Spirit take control of all I do.
For when those trials come, my human nature shouts the things to do;
And God's soft prompting can be easily ignored.

I thank You Lord for the victory that growing brings,
In surrender of everything life is so worthwhile.
And I thank You Lord that when everything's put in place,
Out in front I can see Your face, and it's there You (I) belong.

Chrome running slow on windows 7

2010-01-21T16:50:00.000+08:00

The cool new thing in town is now google wave. Problem is, it runs best only in chrome.

Another problem is, chrome runs very slow on windows 7 after a while.

I've decided to use google wave to compile a public guide on how to solve the problem, hopefully everyone else will contribute too...

Here's the link to the wave.

Netcaster crash course by Simon Lim

2010-01-15T23:02:00.001+08:00

I usually get excited in the first lecture of a module 10 minutes into the lecure because by then I will already know that I'm in for an exciting module this semester.

I was excited the moment Simon started on the gospel today. All that I already know has never been put together so logically and simplified before...

Of brie and supper with Andrew

2010-01-02T22:54:00.002+08:00

Andrew and I went shopping in cold storage at the last minute. Most of the cook food were half priced. So we bought some sausages.

Then we stumbled over the expensive cheese section, and we finally settled for Brie, being the best normal cheese in mousehunt, apart from SuperBrie+, which is not a real cheese. Also, the brie really looked and felt good, not to mention, smelled good too. Well, so here's what happen to the brie...

As you can see, there's a white layer on the brie... It's cheese mold. It's suppose to help mature the cheese... And you ARE SUPPOSED to eat that :p

Back home

2009-12-05T16:36:00.001+08:00

It's good to be home :-)

Oh, my sister got a new bed... It's very comfortable.

And a nice bear for her birthday.

And the wall in the background is the symptoms of SPTM syndrome. Hmm, somehow I don't recall having so much space to study for my STPM. She even has 2 table so that she can alternate subjects. Guess she gets the whole house to herself when I'm not in...

No complaints, I got a room to myself too...

Making NUS webcast sound better with Logic Pro and another free software

2009-11-19T04:04:00.006+08:00

Ever got frustrated over how horrible webcast in NUS can sound? Well, it's 2 days away from the start of the exams, and I'm stuck with webcasting the 2nd half of my econs (which thankfully is not the first exam). It doesn't help that the breeze online lecture for the e-learning week has super low audio quality.

There's this non-stop high frequency hiss around the 5Khz range that super irritating. Not to mention the vocal clarity is pretty poor too. Which leads one to wonder why NUS never bother to provide better quality audio for their webcast when it's so easy (and there are tonnes of free software to do that too) to clean up hiss and noise and improve speech clarity.

Anyway, I decided to pamper myself a little and clean up the noise in real-time. Only problem, the webcast is played in "breeze" adobe presenter, and there's no way of downloading it to play in my beloved iTunes where I can use the EQ to turn down all the high frequencies. HOW? Internet explorer never came with an equalizer.

Ok, for those of you who are wondering, I am using a Mac, and I webcast in windows XP on parallels because stupid Aspresso Classroom webcasts doesn't allow 2x speed using anything but internet explorer. Anyway, that doesn't matter, this method still works anyway.

So for those of you using Mac out there (yea, mac rocks!), here's what I did, and you'll find it quite simple to follow too. What you'll need is:

Logic Pro
Soundflower (which is an open-sourced freeware which is meant to be a bonus product for some professional software)

Firstly, I channeled my sound output from parallels to soundflower. Once you've installed soundflower, it'll add 2 new input and output devices to your Mac's Core Audio drivers (one 2 channel, one 16 channel). As you can see, selecting the 2-channel soundflower as your output device is brainless. Just select it under parallels' Devices menu.

Now, you'll have to catch that from within Logic. So now it's time to fire up logic and select the same soundflower 2ch as the input device.

Again, This is not that hard. Just go to Logic Pro -> Preferences..., and change the input device to soundflower (2ch).

Now, what you want is to crate a new empty project in Logic Pro, which I believe you can do by yourself. Then create a new stereo Audio track, with inputs 1-2 (from soundflower as set in preference), and output to stereo 1-2 (which goes to your built-in output as stated in the preference above). Screenshot attached here for total noobs :-p

Ok, so our channel is set up.

Now, we have to set up our I/O for the audio track. As you can see, it takes input from Input 1-2 and outputs to Stereo Out. I adjusted the equalizer to pull down all the high frequencies (which the human voice will never include anything about 7000Khz, at least for speech, so I pull it down to the minimum). Just double click the dark blue box with the horizontal line will give you the EQ graph. Click and hold those empty squares below the Inserts will bring up a menu, where you can add all the real-time effects. I included Specialized->Speech Enhancer, Dynamicx->DeEsser and Compressor just to hint to you a few effects that could be great for vocal enhancing and clarity. Overall, it should look like that:

Finally, you'll need to click the 'I' down there (it'll turn orange) to monitor the input from soundflower. This way, you'll hear everything from the soundflower outputted from parallels, channeled through the effects and denoise, and outputted to your headphones/speakers. Go on, play that awful webcast again, and it should sound much better, and even super good if you tweak those settings a little. Voila, it's that easy!

You could play with some other stuff like the Specialized->Denoiser, and see whether that works for you. Just experiment till you get the golden voice.

Ok, for those of you who are not using parallels, or if you cannot control which audio device your program outputs to, you'll have to do it the not-so-elegant way. That is, make your whole Mac default output to soundflower, and then make logic output to the built-in output.

To do this, go to System Preference (don't ask me where to find it, you should know!), click on Sound, and choose the Output tab. Under the Select a device...., choose Soundflower (2ch)

The configuration for Logic should remain the same, and it should work like magic. Yup, if you're thinking what I'm thinking... You're most probably right! You can send any sound (from throughout your Mac) into Logic, process it the way you want, and output it. What's MORE IMPORTANT here, you can RECORD anything that plays out from your computer speakers! Go figure... The possibilities only limited by your imagination.

One caveat here. You'll have to leave logic running in the background. That should take about 150MB of RAM. I have 4GB, and I don't feel any effect of leaving logic pro opened, but you may feel the lag, so you may want to close logic once you're done with it. And also, once you're done with all those stuff, don't forget to switch back the audio device (either in system preference of in parallels) to your built-in output or whatever you are using. Else you might be wondering why parallels doesn't have any sound, or why your Mac is suddenly muted. :-)

Ok, I know most of you can't afford Logic Pro (but seriously, at S$698 for student price, it's not that bad an investment after all, you'll never know when those tools come in handy). I am not affiliated to Apple in any way, but Logic is seriously good. I just wish it was more er... polished, like soundtrack pro and logic working better together (or even merged into one)...

Anyway, enough of me rambling. There's a totally free way for you to do exactly what I did (ok maybe with less of the nice effects, but basic EQ and denoise should work fine). Using AU Lab, which comes free with your MacOSX (in the 2nd disc that you've most probably never touched before), you can more or less achieve similar results, which is totally free, and works well too. It will be slightly more technical (there's always a catch to it, huh?), but the reward is sure worth it if your lecturer just doesn't know how to use a mic properly.

I'll go into that once I have some free time (or when I'm bored again after my nth webcast). Stay tuned, mac lovers... I'll be back with more goodies!

Meanwhile, Connie Chung (EC1301) is just so humourous if you webcast her lectures at 2x...

And if you have any tips for EC1301, i'll be glad to have it like... within these 5 days...

It is well with my soul with some history

2009-11-03T23:58:00.002+08:00

The music is just awesome. It has a very strong effect on the emotion. The 2nd verse, especially, just sweeps me up, and throws me right into the turmoil and sorrow of Horatio Spafford, and his beloved wife, during the lost of their children. The feeling of lost, grief, and hopelessness is suddenly so real. Yet, the second part of the verse, though still in the minor harmonic, pumps in so much hope, so much sense of belonging to Christ, that one feels like hope has never felt better than in a time of extreme grief.

"It is through our deficiencies that God is most glorified." Hope will not have it's meaning if we need God any less.

Baffled - Again

2009-10-28T09:37:00.000+08:00

It seems that Raffles Hall did very well so far even at half its usual strength. So well, that people may even start to wonder...what's the secret to keeping such a vibrant and active hall even with so few residents. Jonathan took a closer look at hall life and it looks like we have found ourselves an answer...

It seems time runs backwards in Raffles Hall! No wonder people from outside if hall always complain that events never seem to start on the predetermined time. RH keeps its own time, different from the rest if the world.

Be thankful

2009-10-25T08:37:00.001+08:00

Sometimes we ask, how can we be thankful in such a situation? Well, I just saw a commercial on mobile tv I'm the bus, and there was 3 tips.

Be thankful for your mistakes
- they teach you valuable lessons.

Be thankful for your limitations
- they provide opportunity for improvement.

Be thankful if you're tired
- it means you've made a difference.

Not sure how applicable is this, but it's sure quite encouraging. Especially when our normal reaction toward such events is always complain first, think later. At least, it can take away much of our stress, and make us more thankful people.

Concert surprises!

2009-10-16T01:28:00.002+08:00

Jerome happily came in to my room with a nice letter of absense for me. Considering I'm not really contributing to concert this year, this was a rather pleasent surprise!

Here's the letter explaining my absense from classes.

Not too bad, eh? I am entitled to 2 years leave. Drats...how am I to reclaim 2 years of leave that I've wasted :-s

Raffles Hotel a.k.a. Renovated Blocks

2009-09-12T14:32:00.005+08:00

I was so excited coming back from COMEX, having bought a new external firewire HD, with firewire and all... When I reached my room, I found my roomie on my laptop! He was surfing you tube, and wait, something's very different... His side of the room was now EMPTY!

Ok, so it turns out he was looking for the a youtube video that goes auf wiedersehen... goodbye... to greet me when I arrive back in my room. ARGH!!! depressed xia! he's all moved out and settled down in the new room while I'm still stuck with a whole room of mess taunting me, waiting for me to move. Anyway, he didn't manage to find the video, so there... I caught him while he was looking for it.

Anyway, I decided that I'm going to move bit by bit. Yup, just like your serial connection in EE2007, you move data out bit by bit, complete with handshaking, parity, error checking and all... Anyway, most of the crucial stuff have been moved to my new room, (i.e. my printer, notes, calculator, computer fridge, and everything I need to study. So I'll just study, until I'm tired of studying, then start moving some stuff again...

Cleaning the room is another story. The whole room was dusty with all the construction dust, made my whole pail of water like teh-tarik... But it's rather nice and cooling after moping the floor 5 times. We have new window panes too! They have a very mild, slightly off green tint, but transparent for most purpose. Somehow I feel that they are much cooler than the black ones we used to have, maybe because black absorbs heat. I was wondering whether it is those heat reflecting glass, which lets visible light in, but reflects the infra-red spectrum which heats up the room...hmm... but Tirza pointed out that those would be too expensive to be possibly used in RH... hmm, one never knows, since this whole renovation which seems very minor, already cost a few millions...

Tables are much longer too! nice color, and a lot more plug points than last time.

Lighting have changed, the color is not kinda daylight, but not warm white, which is yellow, hot, and dull. Well, at first, I thought I would prefer cool white, or cool daylight, but this one seems to be perfect, much more natural, and closer in temperature to natural light. It doesn't blink when coming on too, and turns on almost instantaneously when you turn on the switch... must be some kind of new energy saving light.

Ooo, and since I'm taking the end of the split, I get the whole end of the corridor to decorate and keep my stuff. Actually, each split level now has a door, making it quite exclusive/secluded/private, whatever have you. Would think of something to do with that extra space some time later...

Still, there are some hiccups. Some rooms still don't have internet access. Water is still muddy in some blocks. As of now, only 1 block have a proper water dispenser (by proper, I mean with attached filter). But the continuous email updates from our beloved Siew Teng is always ready to comfort the disheartened, and offer a pinch of humor when all else fails. Alas, I'm only 50% done in my shifting... :-(

Can't sleep

2009-09-07T03:35:00.003+08:00

Very packed timetable this semester. Very little time for myself. Day starts at 9, ends at 6, by the time night comes, I'm just too tired to study.

Was worrying of what I should do next semester to lighten my schedule. It seems so impossible, so unlikely, that I will ever improve my life. I keep wanting to escape, hoping that life will be better in future. Keep thinking of how I would have done it if given a second chance...

But fact is, life has to go on, and nothing's changing... The only thing I can change is my attitude...

Keep worrying about what to do in the future, when the current problem is not even over... Gah! I need to worry less... I should just be faithful and take a day at a time...

Hope I will learn to take it to the Lord in prayer...

Very nice song, so meaningful words... No need instruments, the words speaks for itself... And the pictures, they fit just right with the words...

How often we fail to cherish how blessed we are to have a friend...

How often we overlooked the fact that help is waiting just right there...

Bird was outside my window...

2009-06-08T12:47:00.003+08:00

A bird decided to feed on the fruit tree directly outside my window... So I decided to bring out my camera...

There was a yellow bird yesterday, but I didn't manage to bring out the camera in time, maybe we'll see if it comes back this evening... Oh, and I might look for Ying Wei to help me identify the species, or maybe shaun, or Daniel... Whichever...

Long Weekend

2009-06-01T10:46:00.003+08:00

Well, my weekend started on Friday. Woke up to Mrs. Yap call, she was already near to NUS, so I brought her around NUS and had lunch with Timothy. We had lunch in BTC, very nice Jap food. Then we went to Takashimaya, before heading to her brother's house. Dinner was Laksa in her brother's house. Very nice.

Then Saturday, went out to meet mum in Suntec City. Sad, coz it was weekend, and porridge buffet wasn't cheap. Anyway, bought some groceries from cold storage, and a little bluetooth handsfree that is so convenient.

Worship practice was special today, it was JonC's birthday, and a few other celebration. Carol brought some really nice baking from her oven. My, she bakes very delicious.... uhm.... Scottish porridge. I've not idea why they call that porridge, it looks more like those muesli bars, except less crunchy, yet still chewy and nice, and sweet :) I had 2. I think, maybe 2 and a half. Oh, and there was fudge too, and I had 2 of that also.

After church, Simon took a very long time to decide to go out for lunch, Kai Ling was very hungry, and we had lunch at almost 3. It lasted thill 5, so I think it should be called Lunner, or Dinch, or something in between. Anyway, Jerome suggested Lunner, so lunner it is.

By the time we finished dessert, it was already 6 plus. I skipped dessert this time, because it was potentially going to be more expensive than the lunch I had, which was quite an authentic version of a Thai Tom Yam steamboat. I still think the Thai food in the expo back in Seremban last time was much nicer, but then again, you don't get those things all the time, do you.

So here's the steamboat, enough for one hungry person, but quite enough for 2 regular person, especially since it's so spicy, you tend to take a long time to eat. The fish were fresh, so were the prawns, very fresh.

We did finish it eventually, Lydia and I, long after everyone else has finished theirs. Not because we took a long time to eat, but because we had to wait for it to be cooked. :) This was how it looked like after we were done...
