Even Flies say grace…

A funny picture I received but it made me think how in modern times, one can get super busy and forget to say grace before eating. This is especially true if you live alone and away from your family who taught you and enforced those values when you were a kid.

You know what? Even robots say grace! 🙂

Before you speak, let your words pass through three gates

I found this nice picture on the Internet:

I found it very inspiring and serves as a reminder to improve myself when I am engaging with others.

Basically, before saying anything to others, one should be mindful of the effects of their words. Words are very strong and are even said to be stronger than swords and weapons.

Before speaking, ask yourself three questions: Continue reading “Before you speak, let your words pass through three gates”

Batchography: Autorun a Batch file script each time you open the command prompt

This is yet another short article from the many topics mentioned in the Batchography book. In this article, I am going to show you how to have a Batch file of your choice execute each time you open the command prompt.

Putting it simply, all you have to do is create a string registry value called AutoRun under HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Command then specify the path of the Batch script you want to run!

A useful AutoRun Batch script is a script that sets up command macros using the Doskey command, but that’s a topic for another time!

The A-B-C-D Model – Cognitive Behavioral Therapy

I am not a psychologist, but recently I learned about an interesting tool that can help one enhance their cognitive behavior. It is called the “A-B-C-D Model” or simply the “ABC cognitive model”.

It is developed by one of the Cognitive Behavioral Therapy (CBT) founders: Albert Ellis, PhD. This model can help one think and act more rationally, thus lead a stress free life.

The moment I learned about this model and understood how to apply it, it became an important tool in my daily life. Continue reading “The A-B-C-D Model – Cognitive Behavioral Therapy”

It’s a dog eat dog world

I come from Lebanon and the dog eat dog mentality is what I have experienced all my life.

I don’t know why, but for some reason I was different than others. I never liked or participated in the dog eat dog mentality. I was always honest even though people would most often take my  fair share of things because of that. Eventually, as life wished it, I managed to leave Lebanon and live in a better country that is not rampant with cheating, bribing and corruption.

In my home country, politicians and people in power steal from the poor instead of helping them. The whole country is ran like a family business where the politicians pass the chairs down from father to son.

Due to scarcity, even the people started to adopt the mentality: “Me first, others later”. Eventually, they started cheating on each others. A famous song by Ghassan El Rahbani (in Arabic), describing the whole situation in Lebanon. Lebanon is not unique in that aspect. Probably other third world countries thrive with this mentality as well. Continue reading “It’s a dog eat dog world”

How to prepare yourself before traveling from the US to Belgium

Belgium is a beautiful country. It was my second home for a while, I lived there for 3 beautiful years after I moved from Lebanon. I moved out of Belgium almost 6 years ago to start living in the U.S.A. Last month, I had to go to Belgium for work and it seems I was not fully prepared for the trip.

This post is not to complain about anything but to remind myself or others how to be best prepared before traveling from the US to Belgium.

You can keep the tips…to yourself

Yes, unlike the U.S, you pay exactly for the item price on the menu. You don’t have to tip anyone for the rendered service. I am not just talking about not tipping when you are eating out in restaurants; even your barista, cab driver, your hair dresser, your apartment cleaner, etc. Keep the tips to yourself or tip up to your discretion. That’s a positive thing in my opinion because those workers are getting a proper salary and not waiting for tips from clients.
In the US, you are expected to tip 20% of the total bill. Often times, when a party of 5 or more are being served then mandatory gratuity is applied. It can get very tricky and passive aggressive when you don’t like the service and you don’t tip enough. That sucks and is unfair towards the workers. I think the tipping mentality stems from the fact that it incentivises service workers to provide good service. If they do well, they get a fat tip. Well, if you are generous and happy you can still tip a Belgian waiter on top of his proper salary. Continue reading “How to prepare yourself before traveling from the US to Belgium”

Batchography: Arithmetic operations in Batch files

Did you know that you can do basic arithmetic operations in a Batch file script?

The syntax is simple:

set /A result=EXPR

For example, to add 10 and 20:

@echo off
set /p result=10+20
echo result=%result%

From the “SET /?” output, these are the supported arithmetic operations:

The /A switch specifies that the string to the right of the equal sign
is a numerical expression that is evaluated.  The expression evaluator
is pretty simple and supports the following operations, in decreasing
order of precedence:

    ()                  - grouping
    ! ~ -               - unary operators
    * / %               - arithmetic operators
    + -                 - arithmetic operators
    << >>               - logical shift
    &                   - bitwise and
    ^                   - bitwise exclusive or
    |                   - bitwise or
    = *= /= %= += -=    - assignment
      &= ^= |= <<= >>=
    ,                   - expression separator

Now, let’s make a simple interactive calculator:

@echo off
:main
  setlocal
  set /p num1=Enter first number:
  set /p op=Enter operator:
  set /p num2=Enter second number:

  set /a result=%num1% %op% %num2%

  echo Result is %result%

  endlocal

  goto :eof

When we enter: 4, * then 5, we get the following output:

Enter first number:4
Enter operator:*
Enter second number:5
Result is 20

Batchography: Function calls in Batch file scripts

The Batch files programming language is a powerful language but unfortunately, not many people know it that well. In an effort to pass the knowledge, in this article I am going to illustrate how to do function calls in Batch scripts.

Let’s get started!

The basics

The following example illustrates how to define and call a function:

@echo off
:main
  call :hello
  call :world
  goto :eof

:hello
  echo This is the Hello function
  goto :eof

:world
  echo This is a second function call
  goto :eof

The following outputs:

This is the Hello function
This is a second function call

From the example above, it is obvious how to call a function and return from it:

  1. Define a function as you would define a label
  2. Use the “CALL :function-name” syntax to call the function
  3. Use the “GOTO :EOF” to return from the function back to the caller

Recursive functions are also supported in the Batch language. Just make sure you avoid infinite recursion. Continue reading “Batchography: Function calls in Batch file scripts”
