Drink more coffee

This just in.

“What I tell patients is, if you like coffee, go ahead and drink as much as you want and can,” says Dr. Peter Martin, director of the Institute for Coffee Studies at Vanderbilt University. He’s even developed a metric for monitoring your dosage: If you are having trouble sleeping, cut back on your last cup of the day. From there, he says, “If you drink that much, it’s not going to do you any harm, and it might actually help you. A lot.”

Looks like my five or six shots of espresso a day is actually good for health?!

Like anything else, moderation is key I suppose and there’s a lot of conflicting information and research results but I don’t know about this line though…

And the more they drank, the longer they lived. If you’re into that sort of thing.

Consolidation coming soon

With a new business with a fair amount of work coming in, there’s lots to do and even more to get started and settled in. This just adds to my list of things to do in addition to a home, a lovely wife and kid to boot. This means that I’ve got less time than ever to blog. With four blogs, Facebook, Twitter, Instagram and more, there’s just too many social channels that I’ll be consolidating Don’t Panik into another blog that’s has more regular updates.

There’s a time for everything under the sun and there’s a time to start and a time to end. Ten years blogging this blog is a nice mile stone for consolidation. Once I revamp my other blog, I’ll post another notice here. After that has been done, I will configure all domain look-ups to be forward there. This blog will stick around though as an archive.

Aquaponics Project

What’s aqua-what? Hydroponics?

Well, hydroponics is plants in water instead of soil medium. Aquaculture is usually the cultivation of aquatic creatures for food (i.e. fish, prawns, etc). Aquaponics is both together. I think wikipedia has a better description than what I can write (see Wiki entry).

In a nutshell, it’s combining the aquaculture (in my case, Fish) with the hydroponics part. If you’ve kept any fish before, you’d definitely realize that they do produce a fair bit of waste. Otherwise, pet shops won’t be trying to sell you that fancy filter and pump kit plus no matter what, you’d still end up cleaning and changing the water eventually.

Well, let nature do it for you is the name of the aquaculture game. The waste the fishes produce is actually pretty good for plants. So hence my project.

I’ve an outdoor man-made pond with about forty odd Tilapia fishes. They eat and shit a lot. That’s because most of them are edible size by now. Just so you know, these are the 4th generation in my pond (yes, life finds a way to breed) and edible size means over 1.1kg (approx 4.5 lbs). I put a pump in to push the water out into a poly tank what holds hydrokorrels – I can’t find the brand or type I use but this link is pretty close.

The water fills up and gets flushed down and back to the pond. The challenge was that most plants don’t like their roots drowned under water. The roots tend to rot quickly. The solution was inspired by the toilet bowl. Taking some physics lessons, a simple siphon can be created with off-the-shelf PVC pipe parts. This siphon works when the water reaches a certain level. Once the water reaches the right level, it will immediately begin the flush phase where it actually dumps all the water rapidly.

The challenge is to find a fill rate fast enough to trigger the siphon effect but yet slow enough to allow time for the roots to breathe between fill cycles. After some careful tuning, my Laguna 8,000l/hour pump fills my growbed tank in about 10 minutes but dumps the water in 70 seconds.

The diagram is below. Basically the outer 84mm cap is to prevent dirt, leaves and other stuff from clogging the siphon. It does also help you to adjust/tune the water level by creating a barrier to hold the grow bed medium (those hydrokorrels) away from the siphon proper. You won’t need to remove everything just to make adjustments. For the return pipe, the siphon effect is stronger with at least one bend (elbow joint) plus a pipe length of at least half a meter or twenty-odd inches.

Here are my growbed and pond photos.

Adjustment valves to tune the water going into my other filters/hydroponics troughs and the growbed. My 8000L/hr pump is too powerful for a single growbed at the moment.

The return valves/pipes into my pond.

Sweet basil, Thai basil, Mint, rosemary and spinach growing nicely.

The siphon assembly.

My basil and 3 day-old spinach plants. Spinach grows pretty well and fast. I get to harvest them every ten days.

My Tilapia fish. Hardy and dirty. Just what’s needed for the plants. They’re edible too and fast growing.

 

iPhone 4S + Camera + Life

The biggest improvement for me when upgrading to the new iPhone 4S is actually the camera. Yeah, I’ve a ton of apps but my core apps are frequently my communications and networking tools – messaging, email, social media, etc. The next most common app I use is the camera and Instagram.

One thing for sure is that it’s always with me so it’s always the best camera — even when I’m lugging a truck-load of photo equipment, it still allows me to document, capture and basically, photo-log my activities.

More importantly, it lets me capture events and people important to me. I’ve every photo taken since my iPhone 2G days and the count is in the five digits. Browsing through the photos is like stepping back in time.

Webcasting

One thing I’ve observed in many local churches is the minimal use of internet technologies available.

Websites and email aside as those are to be expected of any entity or organization today. I think it’s time they embrace more tools to enable better and greater reach.

Recently, our cell group scheduled a session with the esteemed Reverend Lim Kar Yong of STM to teach us on a series of Parables. Well, we decided to enlarge his audience by combining with Kinrara cell group via web-cast. Of course other members who could not make it could also attend the webcast session. Slides, audio and video were broadcast at standard definition. It was evident however that our regular Malaysian home ADSL service (Streamyx) would not cut it even though the webcast only required a downlink of about 350kbps. On a 1mbps line, the video would be choppy and occasionally drop out.

It was an interesting experiment though and one we would continue for the next three weeks. For those who couldn’t attend the webcast, we have audio recordings and if you want to watch, we have a HD video recording of the session as well!

I’ll blog about the tools we used in a separate post later this week.

Hee Lai Ton, Sri Kembangan

It’s Chinese New Year and it is usually filled with eating. Well, yes, there’s all the family reunions, meeting long lost relatives and friends but it’s always around food. It used to be that most breakfasts, second breakfasts, brunch, lunch, afternoon tea, evening tea, dinner and suppers were all home-cooked food. Today, most people have no time to prepare such meals from scratch and resort to eating out. Even in my family, we’ve started to supplant home cooked dishes with store bought ones. Of course the main meals (the eve, first and second day of the New Year) is still home cooked.

Anyways, along with Chinese New Year, it was also my father-in-law’s birthday. It’s kinda cool to have your birthday around Chinese New Year because everyone will know about it and you will get more presents! Anyways, I digress but we got him a fancy iPad2 which I setup to keep him busy with lots of e-mags, news portals, flip board and more.

For lunch, we went to this restaurant in Sri Kembangan that is famous for it’s Poon Choi. Read the wikipedia link if you want to find out more but it is translated wrong in my opinion. It should read “basin dish”. Inside this boiling pot, we had chicken, oyster, vegetables, pork, prawns, bean curd, fish maw, bean curd skin, abalone, eel, fish balls and more…

Anyways, the food is pretty decent fare but the highlight of course was the Poon Choi which was full of stuff to eat. There were other dishes of course such as fish-wrapped oyster with sea weed balls, suckling pig and stewed goose feet with sea cucumber. I ate everything except the feet — I don’t eat legs… chicken legs, pig legs, cow legs, fish legs, human legs… whatever.

The food is pretty good and it’s a pretty packed on the Saturday we went. I don’t know if the other dishes are worth going for though. They’re famous for their Poon Choi so if you are longing for that dish, the one they serve up is pretty good.
