The impact of LED bulbs on our nature

L.E.D bulbs are unquestionably a revolutionary product that can save electricity compared to the incandescent bulbs. The LED bulbs have long life compared to their incandescent counter parts and also consume less electricity.
The LED bulbs that are available from stores have a life of approximately 5 years on 8 hours of daily use and the companies give 1 or 2 years replacement guarantee. Now comes the problem. The incandescent bulbs have zero percent plastic, but LEDs are almost completely made of plastic. When they expire they are also contributing to the landfill and will create big problems. They have electronic components that are also dangerous when damaged.
So, when touting LEDs as a big saver, the companies should also have the responsibility to take back the expired ones and recycle properly instead of going to land fill.
The big benefit is that most LEDs may have only one or two components damaged. So, they can replace the component on very low cost and sell the refurbished ones.
Light Emitting Diodes theoretically have life expectancy of 50,000 hours and it is almost 12 years on 8 hours of daily use. Also, the light output also decrease in course of time. This is mainly because of the failure of the components of the bulb and not the LED itself.
In India, we urgently need a good framework for gathering and properly recycling and disposing electronic waste otherwise this will be another danger in near future.

*FIXED* Setting you Railo / Lucee server to use TLS 1.2 by setting to use Java 1.8 instead of Java 1.7.

TLS 1.0 support is being dropped by more and more platforms. If you are using your Railo / Lucee server to communicate with the service that have dropped the support using TLS 1.0, the request will not be honored. Here are the steps to have your Railo/Lucee server to use Java 1.8 instead of 1.7 and avoid this error.

First verify the version of Java that your Railo Server is using.
Go to Server Admin and check the version of Java used by Railo server. Instead of the 1.8.xx as show in the screenshot it will be 1.7.xx


So, we need to install JDK 1.8 if not yet installed in the machine.


  • Install JDK 1.8. 32/64 bit according to your server OS.
  • Open Railo-Tomcat Service Control.
  • Stop Railo.

  • In the Java tab, give the jvm of the newly installed JDK. Something like C:\Program Files\Java\jdk1.8.0_121\jre\bin\server\jvm.dll.
  • Restart Railo.


Check the version of Java used in Railo Server Admin, it will be 1.8.

Now your requests to the server will be TLS 1.2 and they will be honored.

100 days after demonetization in India - points to note

After 100 days of demonetization, the chaos surrounding the shortage of currency has subsided. Banks and ATMs are honoring customer's currency requests better.

Indeed the demonetization is publicized as a war on black money, but it is not the only aim. Because the government is well aware that this step alone will not help in finding the assets stashed as property and other means.
Also, as anyone might expect, new fake currency notes are already in circulation. So, what could be the motive for demonetization?
  1. To force citizens to use digital currency to make them accountable to Tax.
  2. To force citizens to keep their money in the bank so that the Central Bank can "Overcome the Zero Lower Bound" on the negative interest rates.
  3. Reduce cost of printing and circulating money.

This may not be a welcome move regarding Indian Citizens who are already fed up due to multitude of tax and bribing by officials and politicians.
By promoting digital currency, the government will be able to reduce the cost of creation of currency notes. Usage of digital currency requires the users to pay the service charge to some party, either the provider or the bank. So, effectively, the cost of currency creation is directly transferred to the citizens.

The majority will consider this move a positive one only if:

  1. Income Tax and VAT rates are reduced.
  2. Service charge is completely avoided for digital payments.
  3. Easy, secure and widespread use of POS machines.
The government have modified the Tax slab recently, but there is no decision yet on waving off the service charges especially at petrol pumps. These needs to be addressed quickly otherwise the whole exercise will be a black mark for the government.


Dangers Ahead
When using currency one needs to be scared of the robbers who can physically access your money. The theives now have sophisticated tools that can be used to skim the ATM card and withdraw money.
But when things goes digital and we are forced to store the money in the bank accounts it will provide bigger opportunity to them. Added to the fact that even most of the literate and working class are lacking security skills on the smart phones, the risk is multiplying. The Android phone users can easily be tricked to install fake applications and the hackers can gather all information from the phone to get money out of their bank accounts. There haven't been many instances of losing money using hacked smart phones, but widespread using of low cost internet and digital payments will soon be a point of risk.

There are several important steps that needed to be taken by the government regarding security and various taxes before implementing such a bold move. Now that the demonetization is already done, the steps to address the security concerns and get the confidence of the consumers should not be delayed.
