On Driverless Cars

June 15, 2014 by Rakhitha Karunarathne | No Comments | Filed in Tech

It seems that world will get driverless cars little sooner than expected. And by the looks of the first Google prototypes it will be a revolution in design department too. Similar to moving from a QWERTY keyboard to touch phone. This has a potential of changing lot of things.

In long-term driving test will become a thing in the past. People who make a living by driving around people or goods may be in trouble. Also individual car ownership may also decline and instead car pooling communities will develop. For that course people will have to get through the urge to own a car to make a personal statement.

Money can buy happiness, if you know where to shop!

50 Things Money Can't Buy ()

50 Things Money Can’t Buy

This image is doing its rounds on Facebook and to be frank, I think we can buy many of these things with money. Not in a bad way by the way. You just need to know where to shop.

IMO why most of us think money can’t buy happiness and many other things in this list, is partly because most of us don’t realize what we really need. For example what does respect, class, a good hair day, luck, good epitaph means? I may be wrong, but in my opinion these are things one can live without.

And for the some of the things in the list got nothing to do with money. For example saying money can’t buy you Appreciation of simple things is like saying you can’t make apple juice with oranges. This post might sound really harsh or it might even look like I am trying to sell insurance or some get-rich-quick thing, but that is not the intention. I am just writing down some stuff that was running through my mind for a while about whole money cant buy you this and that thing.

Bringing the TV Online with an Android Mini-PC

November 24, 2013 by Rakhitha Karunarathne | No Comments | Filed in Movies, Tech, TV

I had this idea for a while to connect the TV with internet and LAN. So that I don’t have to turn on  the computer every time I want to stream something. Also it will remove the need to connect wires between computers and TV when I want to watch something on a larger screen.

A smart TV with all those capabilities are off my budget. And it’s not worth spending that much on such a project since we watch TV less than two hours a day. Therefore I was on the market looking for smaller devices that could plug-in to a HDMI port and stream media.

Chrome-cast and similar devices seems nice, but they have one major problem. It rely on some cloud services, phone or another computer to work. Also when stream content from local network, the media server (crome) has to render the content and stream the rendered video to device. That needs a very fast LAN. I was looking for something that can do its own rendering. So that there will be less load on network. It also had to power from TVs own USB port and connect to network via WiFi. And  it should play 1080p  HD Video with good quality.

Difference Between 64-bit and 32-bit Computing and What It Means for Phones

September 15, 2013 by Rakhitha Karunarathne | No Comments | Filed in Tech

You can probably notice that discussions are popping up on advantages of 64-bit systems. It is mostly linked with Apples 64-bit A7 processor in new iPhone. If you just search the web for iPhone and 64-bit, you will find that some call it innovation, some say it gives huge advantages including major performance boosts. And some try to explain it to laymen using oversimplified if not completely incorrect examples.

I am not a fanboy of Apple or Android. In case you want to know, I am still using a Nokia phone which I purchased when Nokia was still the industry leader. However I am developing software that push the limits of 32-bit and need 64-bit to run at their best. So I know a thing or two about what I am going to say. Here is my take on differences of 64-bit and 32-bit. I cannot make it too simple, because then it will not give the correct information. But I’ll try to keep it as simple as possible.

Why Sri Lanka Need Rs 15000 or Even Cheaper Computers

August 6, 2013 by Rakhitha Karunarathne | No Comments | Filed in Sri Lanka, Tech

I came across this post on readme.lk recently. It’s about upcoming policy on import of used computer systems to cut e-waste. Which is good. Because we do very little recycling. And e-waste consist of mostly non recyclable material with many toxic chemicals.

However what I do not agree is the statement which claims Sri Lanka no longer need 15000 LKR systems. 15000 LKR systems are exactly what Sri Lanka need. But of course, I am not talking about 15000 LKR junk. But reliable working systems that can increase IT penetration of a country.

Upgrade to Mobitel Mega-Plan and Huawei E5331 – A Review

August 3, 2013 by Rakhitha Karunarathne | No Comments | Filed in Me, Myself & I, Sri Lanka, Tech

Huawei E3551Over last few years my wife and I used two Mobitel 1290 packages to connect two of our computers to internet.  We used two mainly for extra bandwidth and speed. With introduction of Mobitel Mega plans, we dropped one connection and upgrade the other one to 20Gb package. It let you use multiple SIMs with same connection.

Our 3G dongles were from stone age, and speeds were limited to 7.2Mbps down-link and about 300kbps up-link at best. Ofcourse these are theoretical numbers and the down-link was much slower. One of the dongles was too old to work with windows 7 and we are down to one. It was time to upgrade devices.

New device of choice was Huawei E3551 portable 3G WiFi router. Here is what I liked about it.

29 Going 30

May 20, 2013 by Rakhitha Karunarathne | 2 Comments | Filed in Me, Myself & I

Well, today is the last day of my twenties. In few more hours I’ll be 30 :). It was a good time. Many things in life change in twenties. But you do continue doing some of the things you did earlier. But the difference is earlier you did them because you had to. Now you do them because you want to. Like studying.

During early twenties you move on from being dependent on your parents for many things to being independent. You work your ass off to build up your career. In twenties you do have money, health and energy and not that much responsibilities to worry about. So the fun continues. And once you pass the mid way point of twenties, you start to focus more on having a life.

Display Flicker After RAM Upgrade? Check PSU Outputs!

March 4, 2013 by Rakhitha Karunarathne | No Comments | Filed in Tech
These RAM are now officially retired.

These RAM are now officially retired.

In case you are wondering why your monitor flicker and computer crash after a hardware upgrade, this might be the answer. New hardware can drive the voltage bellow 5% tolerance level required to run the PC smoothly. You can check the voltage level in BIOS or with a Multimeter. But don’t rush to buy a new PSU. It is most likely a loose power connector.

Here is what happened. It’s a bit long. I decided to give a RAM upgrade to the old computer that we are having. I bought  two Samsung 1GB sticks (DDR 400Mhz) from a local refurbished RAM shop. After the upgrade computer simply kept crashing while loading windows. If I plug just one of the memory cards, computer boot up, but it was very unstable. Display kept flickering and eventually it crashed.

Full Airport Experience

February 17, 2013 by Rakhitha Karunarathne | No Comments | Filed in Sri Lanka, Travel

ViewFromPublicViewingArea

This Saturday  I went to Colombo airport to drop off my wife. Usually once I drop off someone, I leave the airport as soon as they pass the scanners to go to check in counters. But since this was Saturday morning and there was nothing much to do afterwards, me and another friend who came to drop off his wife decided to hang out a little longer.

He remembered that there was some place you can watch take offs and landings which he visited when he was a kid. We decided to find that place and spot some aircrafts.
