    Kha Lay

    In Burmese, it means child.
    Kha Lay Ba Wa means childhood. The days of the innocent childhood became a theme of the song composed by Sai Kham Leik and sung by Sai Htee Saing. We had a Kha Lay Ah Thinn (Children’s Club).

    Kindness

    Random acts of kindness may be reciprocated even by seemingly bad people.
    My father volunteered at a “Bain Phut Ah Thin” for rehabilitating opium addicts. He gave a rehabilitated addict some money to pay for the fare back home. It was an act of random kindness.
    During the Second World War, my parents and his siblings decided to take refuge at Neikbeinda Hills in Prome. My father sent his assistant ahead of him. Unfortunately, the assistant encountered a group of bandits. He pleaded the bandits not to take away his saya’s possessions. When the bandit leader learned that the saya was my father, he decided to guard the assistant on the way to the Neikbeinda Hills.
    The leader also offered a surprise gift — a box of condensed milk — for my father.

    Lokathana, Venerable

    U Lokanatha

    • He spent his life practicing and preaching in Burma & going on Dhamma Duta missions to neighboring countries.

    Alumni

    • In Latin, there are four terms :
      alumnus for “male student”
      almuna for “female student”
      alumni for “male students”
      alumnae for “female students”.
    • In modern usage, the term “alumni” applies to all students.

    Days of Month

    • According to “Ripley’s Believe it or not”, a graveyard inscription has February 30th.
    • Grapevine says that Followers of two Carsars took away a day each from February to make July (named after Julius Caesar) and August (named after Augustus Caesar) to have 31 days instead of 30.

    February became the shortest month of the calendar year with 28 days. It was given back an extra day on a leap year.

    The earth takes about 365.2422 days to revolve round the sun, so the discrepancy became 0.9688 day every four years (or 97 days in 4 centuries).

    In Gregorian calendar, a leap year is defined as a non-century year that is divisible by 4, and a century year that is divisible by 400.

    In the early days of Computing, a Hack is defined to be a “useful and/or beautiful piece of code.”

    Hacker

    • Some students, who worked at Massachusetts Institute of Technology (MIT) Computing Laboratories, preferred working on code rather than attending courses.
    • They feel proud of their Hacks and are addressed as Hackers.
    • Over time, Unethical Hackers emerged.
    • Ethical Hackers also rose to defend against the Unethical Hackers.
    • Most people do no know or care about the difference between Ethical and Unethical Hackers.

    Ethical Hackers

    • They try to break the security of computer systems and applications.
    • They propose solutions to defend the possible attacks of Unethical Hackers.
    • They are known as White Hats.

    Unethical Hackers

    • They inflict damage to hardware, software and data systems.
    • They may steal and sell sensitive information.
    • One study says that it is safer and lucrative to be a Criminal Hacker (also referred to as Cracker) than selling drugs (which can lead to imprisonment and death in some countries).
    • The underground business for malware (viruses, Trojan horses, …) is valued at multi-billion dollars.

    There was a joke from one comedian when the movie ‘Malcolm X’ came out. [Malcolm X was an American Muslim minister famous in the 1950s and 1960s and was assassinated Feb 21, 1965.] The joke was that he, the comedian, has been away from the movies for quite some time, he did not know and therefore missed the Malcolm I through IX.

  • Disaster

    by Hla Min

    Updated : Apr 2026

    It is sad to learn about disasters happening around the world.

    Several are natural disasters. A few are man-made disasters.

    Despite advantages in technology, there is no reliable and cost-effective system yet to predict and/or prevent disasters.

    There are general predictions like “the coming of Doom’s Day”.

    Some are serious about “nuclear wars” (and similar scenarios of “Apocalypse”) and spend exorbitant money to order or build underground hideouts in remote places and also extensive “evacuation plans”.

    There are some predictions based on past data. e.g. “The next big earthquake is due. You should take extra care since you are living on a fault line.”

    A few could not and would not leave their homes even when the authorities issued “mandatory evacuation”. Some evacuated, but they when they returned they found their houses missing or being vandalized.

    Disaster recovery is not simple.
    The countless lives lost to Cyclone Nargis and its aftermath could have been minimized with proper planning and mobilization of the rescue teams.

    Kudos to the individuals and organizations that offer “disaster relief funds”. But, disaster relief is at the tail end.

    U Khin Maung Zaw (EC76) added :

    Disasters, by nature or man – made, happen all over the world, more so as the so-called climate change and population explosion exacerbated the conditions.

    In the US, several governmental, NGO and private/public organizations are stepping up their efforts to educate, prepare, assist and mitigate the people impacted by all forms of disasters.

    I just opened up my disaster backpack this morning, in the process of inspecting, refreshing and refilling the contents in there.

    There are several websites, ready.gov/kit, Red​cross, FEMA Apps which will explain what items you would need in this emergency kit, survival and medical supplies, food among others.

    Some years back, there was a website called threefoldthreeway, explaining these items as well. They initially thought you would need at least three days with off supplies & food before the rescue folks contact you.

    Some disasters in the past decade taught us that three days may not be enough in many circumstances, and now recommend to have two-weeks worth of supplies and food.

    The region that I live has been overdue for severe, 8.0+, earthquake by the experts.

    I do have enough supplies of food and water but I need to collect toilet facilities, like cardboard toilet, shower facilities among several items.
