DEBUGGING

Debugging is a methodical process of finding and reducing the number of bugs, or defects, in a computer program or a piece of electronic hardware thus making it behave as expected. -->
The debugging skill of the programmer is probably the biggest factor in the ability to debug a problem, but the difficulty of software debugging varies greatly with the programming language used and the available tools, such as debuggers. Debuggers are software tools which enable the programmer to monitor the execution of a program, stop it, re-start it, set breakpoints, change values in memory and even, in some cases, go back in time. The term debugger can also refer to the person who is doing the debugging.
Generally, high-level programming languages, such as Java, make debugging easier, because they have features such as exception handling that make real sources of erratic behaviour easier to spot. In lower-level programming languages such as C or assembly, bugs may cause silent problems such as memory corruption, and it is often difficult to see where the initial problem happened. In those cases, memory debugger tools may be needed.
In certain situations, general purpose software tools that are language specific in nature can be very useful. These take the form of static code analysis tools. These tools look for a very specific set of known problems, some common and some rare, within the source code. All such issues detected by these tools would rarely be picked up by a compiler or interpreter, thus they are not syntax checkers, but more semantic checkers.
Often the first step in debugging is to attempt reproduce the problem. This can be a non-trivial task
After the bug is reproduced, the input of the program needs to be simplified to make it easier to debug. For example, a bug in a compiler can make it crash when parsing some large source file. However, after simplification of the test case, only few lines from the original source file can be sufficient to reproduce the same crash
After the test case is sufficiently simplified, a programmer can use a debugger to examine program states (values of variables, the call stack) and track down the origin of the problem. Alternatively tracing can be used. In simple case, tracing is just a few print statements, which output the values of variables in certain points of program execution.

Epitome of equality

First of all This is not to demean any religion.. I am a Hindu by birth, but yes I respect all religions .I offer my daily prayers , fast on holy days , but there was something that was disturbing me . God as per me was a Friend, someone who was by my side always , someone who was a dear friend , but this is not what everyone else thought , for others he was the Judge who gives his verdict always and punishes anyone and everyone . Walk into any temple and you would see , if you have money , you will be treated in a way as if you are the ONLY disciple of the God . I have had too many experiences where I was treated as a second class citizen in the temple . Why? Well I could not afford giving thousands as donation. This is not how it should be , God looks at each one of us with the same divinity .As I mentioned God for me is a friend, so tell me, do we chose friends based on their bank balances? Do we give our verdict on them ? then how can God do it? I know many of us would ...

Prosperity blueprint: How one investor turned real estate into a living energy field for wealth

Wealth vastu case study: How one investor turned real estate into wealth In this wealth vastu case study, we explore how Choden, a seasoned investor, transformed underperforming rental properties into a thriving energy field of wealth using ancient Vastu principles, energetic space alignment, and simple rituals. The outcome—lower vacancies, higher ROI, and a profound sense of financial ease and energetic harmony. Why do some properties multiply wealth — and others drain it? Have you ever walked into a home that immediately made you feel calm, confident, and somehow richer inside — even if nothing in your bank account changed? And then, there are those other places — beautiful on paper, perfectly located — yet every time you enter, something feels off. Money slips away faster. Tenants leave. Repairs pile up. You can’t quite explain it, but you feel it. That’s where our wealth vastu case study begins — not with numbers, but with energy. This story isn’t about buying more l...

Cutting people off isn’t strength—It is a trauma response

Your ability to cut people off and self-isolate is not a skill you should be proud of—It is a trauma response Cutting people off and self-isolating may feel like a protective shield, but it is often rooted in unresolved or unhealed trauma and an inability to depend on others. While these behaviors seem like self-preservation, they end up reinforcing isolation and blocking meaningful connections. Confronting these patterns, seeking therapy, and nurturing supportive relationships can help break this unhealthy cycle. Plus, a simple act like planting a jasmine plant can symbolise the start of your journey towards emotional healing. Why do we cut people off and isolate? If you’re someone who prides themselves on “cutting people off” or keeping a tight circle, you might believe it’s a skill—a way to protect yourself from betrayal, hurt, or unnecessary drama. I get it. I’ve been there, too. But here’s the thing: this ability to isolate yourself is not as empowering as it may seem. In fact, i...
