Go - constant variables and const keyword

Sun, 12 May 2024 00:00:00 +0000

Brief

Programming languages have the notion of constants which means “variables that can not be mutated once declared and initialized”.

Go also has almost the same meaning, but in a different context. To initialize a variable as a constant with a value of 10, we can do something like this:

`1`	`const DISCOUNT = 10`

In Go, constants mean “storing a literal to a variable”, this can be seen as a version of pattern matching in Erlang.

What is Byte Masking and how useful is it?

Mon, 18 Sep 2023 00:00:00 +0000

Part of the operators we get introduced to when learning to program is Bitwise Operators, examples are:

The Bitwise OR | (a single pipe character)
The Bitwise AND & (a single ampersand character)
The Bitwise XOR ^ (a single caret character)

Each of these has its usage, a refresher can be demonstrated considering these two variables foo=1 and bar=0

For The Bitwise OR(|) Operator

1
2
3

const foo = 1, bar = 0
console.log(foo | bar)
-> 1

For the bitwise AND(&) operator

1
2
3

const foo = 1, bar = 0
console.log(foo & bar)
-> 0

For the bitwise XOR(^) operator

1
2
3

const foo = 1, bar = 0
console.log(foo & bar)
-> 0

This seems pretty basic until you understand it is not.

Creating multiple copies of objects in Ruby

Thu, 07 Sep 2023 00:00:00 +0000

Since everything is an object in Ruby having a functionality that can duplicate objects is not a bad idea.

Ruby ships with two methods for making copies of an object: the dup method and the clone method.

In Ruby, all variables hold a reference to an object. In a case where a section of a code modifies an object that is not meant to be modified, it is ideal to make a copy of that object to be used in that section of the code, protecting the integrity of the copied object.

When to use puts, print, and p in Ruby

Tue, 05 Sep 2023 00:00:00 +0000

Usually, programming languages have methods for printing out variables. Ruby is not an exception. We will explore the 3 popular methods for printing variables in the Ruby Programming language.

The `print` method

The way print(var) works is basically converting its value to a string by calling the to_s method on the object(everything is an object in Ruby) before printing the value and returning nil to its caller.

1
2

num = 123
print(num) # -> 123 => nil

The print method can be easily used for concatenating strings

tar (child) xz Cannot exec No such file or directory

Mon, 10 Jul 2023 00:00:00 +0000

The error:

`1`	`tar (child): xz: Cannot exec: No such file or directory`

Is majorly an issue with the xz command not found on the host machine.

To verify, run:

`1`	`whereis xz`

Fix

To fix, use the installation command for your Linux distribution:

sudo apt-get install xz-utils          # Debian / Ubuntu
sudo yum install xz                    # RHEL / CentOS
sudo zypper in xz                      # OpenSuSE
sudo pacman -S xz                      # Arch Linux

Then untar again with:

Optimizing Merge Sort

Tue, 20 Jun 2023 00:00:00 +0000

Going through Chapter 2 of CLRS, I was introduced to the concept of divide and conquer, which is a very interesting algorithm technique, and a popular example of the divide and conquer algorithm is merge sort.

Merge sort has an Θ(nlgn) run time, which is very good for large inputs. When the input is sufficiently small enough, the algorithm has a worse run time compared to a sorting algorithm that completes in Θ(n^2) time. One of the exercises is to create an optimized version of the merge sort that runs the original merge sort algorithm for sufficiently larger inputs where it shines and to run insertion sort [ Θ(n^2) ] when the input size is sufficiently small enough. I have a solution for it on my Clio website, this post walks through the process for the solution.

Searching for a pattern in the man pages

Tue, 20 Jun 2023 00:00:00 +0000

To search through the man pages for some keywords, use the -k option.

man -k [keyword]

This shows a result of the commands, and routines that match the keyword with a one-line description of what they are about.

man -k passwd shows all the possible entries for passwd in the manual pages.

The apropos

The man -k [keyword] command is similar to a help utility called apropos which is available both on Unix and Linux. See it as a shortcut.

Know the man(nual) pages

Sun, 18 Jun 2023 00:00:00 +0000

There are many ways to get help as a Linux administrator, manual pages are one of them as they are always close - accessible via the terminal.

The manual pages, called “man pages” is a local documentation and description of software packages, drivers, routines, and libraries on a Linux machine.

To use it run man [command|library|routine|driver] and replace the command with the name of a command to find a manual.

Send message from a service worker

Sun, 22 Jan 2023 00:00:00 +0000

Communication between service workers and the clients browser window can be achieved by simply doing:

1
2
3

self.clients.matchAll().then((clients) => {
  clients.forEach((client) => client.postMessage({ msg: "Hello from SW" }))
})

The variable self is a reserved keyword in a service worker context. It references the global scope of the current worker execution scope and has some useful properties. It is like the window object of a JavaScript browser context.

In the above snippet, all the clients that run the service worker are loaded, then the .postMessage is called to send message directly to the original javascript runtime of the service worker.

Autocompile Go

Sat, 21 Aug 2021 00:00:00 +0000

First, install CompileDaemon:

`1`	`$ go get github.com/githubnemo/CompileDaemon && go install github.com/githubnemo/CompileDaemon`

Then, from the root of the project, create a Make file:

`1`	`$ touch Makefile`

And add the below content:

GOCMD ?= go
GOBUILD = $(GOCMD) build
GOCLEAN = $(GOCMD) clean
GOTEST = $(GOCMD) test
GOGET = $(GOCMD) get
BINARY_NAME = project_name
BINARY_UNIX = $(BINARY_NAME)_unix

default: all

all: test build
build:
	$(GOBUILD) -o ../$(BINARY_NAME) -v -ldflags="-X main.VERSION=$(TAG)"

test:
	$(GOTEST) -v ./...

clean:
	$(GOCLEAN)
	rm -f $(BINARY_NAME)
	rm -f $(BINARY_UNIX)

run: build
	./$(BINARY_NAME)

dev:
	CompileDaemon -build="$(GOBUILD) -o ../$(BINARY_NAME)" -command="../$(BINARY_NAME)" -color="true" -exclude-dir=.git -exclude=".#*"

Finally, from the root of your project:

Erlang Functions

Mon, 21 Jun 2021 00:00:00 +0000

When programming Erlang, you should think like you are writing an English essay. In Erlang, functions are not very different to what a traditional programming language offers, but they are written very differently in Erlang.

To declare a function in the Erlang Repl, you will have to use the fun keyword.

`1`	`Name = fun(X) -> X.`

The above code will store the the declaration of a function called Name and would receive an argument called X.

Erlang Pattern Matching

Tue, 15 Jun 2021 00:00:00 +0000

If you come from a conventional programming language background, the way Erlang handles assignment is expected to look wonky, but it is not.

There is nothing like an assignment in Erlang programming language; there is a different approach to accessing values in memory, which is the pattern-matching operations.

With Java, PHP, Python, C, C++, and likes, the = symbol implies take the values from the right, and store it into the memory, then give me the reference of the location in memory and store it in the expression at the left.

Erlang Variables

Mon, 14 Jun 2021 00:00:00 +0000

If you have worked with other languages like JavaScript, Java, Python etc, you would be surprised by what Erlang understands as variable.

In Erlang, variables starts with uppercase letter, thus, C, X, Ape, Ant are all valid identifiers for Erlang variables.

Variables can not start with lowercase letter or begin with a number.

Erlang variables can include can alphanumeric characters, an underscore and @ symbol.

1
2
3

X = 1. %% Valid
y = 2. %% Invalid
1X = 2. %% Invalid

When assigning to a variable - as we do call it in other languages, Erlang actually does something called pattern matching. Comparing the values on the right to the values on the left.

CSS action pseudo classes

Sun, 13 Jun 2021 00:00:00 +0000

Without JavaScript, dynamic UI is possible with just CSS action class selectors.

Case study

Help text for input element which is only visible when the input is focused.

The HTML

<div class="input-cont">
  <input type="text" placeholder="Focus me" autofocus />
  <span class="help" data-help="Enter your email"></span>
</div>

To achieve the above, a span holding the help text in a data-help attribute as a sibling to the actual input. Both the input and the span are children to a parent div with class name input-cont.

An introduction to Erlang

Sat, 12 Jun 2021 00:00:00 +0000

If you have used WhatsApp or Facebook Chat, then you have one way or the other interacted with an Erlang-backed system.

Erlang is a language created for the telecommunication industry by Jor Armstrong, Robert Virding, and Mike Williams in 1986. It was recorded that Jor Armstrong claimed he was provided a library and did not know what to do with it, then they taught him to solve the reliability and concurrent problem of the telecommunication industry, and that gave birth to Erlang.

CSS counters

Mon, 07 Jun 2021 00:00:00 +0000

CSS can keep count of numbers without writing any additional JavaScript.

It does this by taking note the amount of time a CSS block affects a page then incrementing the counter for that block if the counter-increment rule is implemented.

For example:

1
2
3

input:invalid {
  counter-increment: invalid-count;
}

With no JavaScript at all, CSS understands that whenever there is an invalid element, it should increment the count for the invalid-count identifier.

Structural CSS Selectors

Sat, 05 Jun 2021 00:00:00 +0000

Yeah, you read that right. Let go straight into it!

A Test Case

Can you interprete this CSS selector query?

1
2
3

p.title:first-of-type {
  color: red;
}

Let me think like you would:

Select every P element that has the class name of title and apply the color red to the first of its type.

<body>
  <p>Lorem Ipsum</p>
  <p class="title">Paragraph 2 (shows in red color)</p>
</body>

You think you’re right.

Dockerized Node/Nginx, MongoDB, Redis app setup

Thu, 19 Mar 2020 00:00:00 +0000

Introduction

Docker is an app development tool that eases the process of creating, running, and deploying applications. It uses the concept of containers which work just like a Virtual Machine does.

While Docker runs more like a Virtual Machine does, it is more advantageous than a VM.

It let us define OS-like images like we are writing an actual OS that includes the only tools that we need, aside this, Docker utilizes the concept of layers which makes its images very much extensible. With this little feature, developers, sysadmins and devops engineers prefer it more. And since it has been in existence, Docker has witnessed widespread usages making it one of the defacto tool for software development, testing and delivery.

SocketIO - App structure and architecture

Sun, 15 Mar 2020 00:00:00 +0000

Introduction

SocketIO is a JavaScript library that makes developers’ lives easier when dealing with web socket and socket programming. This is the fact that SocketIO has abstracted out all the low-level and tedious steps that are associated with setting up a socket server and client; it has made the question of programmers be “How can I structure my application.”

While I have done different types of socket implementations, I will walk us through a setup that has always work for me and has proven to be the best in cases that I have had to use SocketIO.

Asynchronous Javascript

Tue, 03 Mar 2020 00:00:00 +0000

In computation systems, names like concurrent, sequential, parallel, serial, synchronous, asynchronous, non-blocking, shared state, message passing, and likes, stand as a forbearer for the actual task that happens in a system.

While all of the above techniques have their use cases, in the world of JavaScript, asynchronous and synchronous programming never leave the tongues of its programmers.

In his Concurrency glossary, slikts (dabas@untu.ms) wrote about asynchronous, he said:

Asynchrony means “not happening at the same time”, and asynchronous message passing is a communication model that does not require the sending and receiving to be synchronized, meaning that the sender isn’t blocked until the receiver is ready.

Menu system in Node Apps like WordPress Menu

Sat, 25 Jan 2020 00:00:00 +0000

You might have been in this kind of trap before or currently in one, well, I just want to tell you that I know your pain.

In a custom built CMS, managing of Menu and navigation in the site from the Admin Dashboard is a requirement. While it is interesting to use, it is not as interesting to build.

I just walked past this process, here, I am sharing how I have conquered it.

ReactJS - Unexpected closing tag

Sat, 25 Jan 2020 00:00:00 +0000

Beginners in ReactJS often face this kind of error:

It is not just with inputs, it is with all HTML elements that does not expect a closing tags, they are called empty elements. A list of these tags could be found here.

To solve this very easily, we just have to follow the HTML semantics by ending all empty elements with /> instead of >

So inputs should look like this:

ReactJS - Inplace Edit component

Mon, 20 Jan 2020 00:00:00 +0000

Last time, I was trying to render a data table and I thought that I should make some fields editable right in the table listing. It is interesting to note that I never thought about any NPM library for it, so I went all out to create a simple but effective solution for myself.

In this post, I will demonstrate how I created an editable component. The component would be able to use different form fields and notify the parent if any change has been made. That said, Let’s move….

AdonisJS - Event

Sun, 19 Jan 2020 00:00:00 +0000

Modern application development requires that some actions are carried out when a point of the application is reached.

Tasks like confirmation email, invoice generation, logging and profiling are few of things that requires to be carried out in specific regions of application flow.

These actions that are triggered are called Events. Events in modern application development make code execution after a web request to the server has been completed to be possible.

AdonisJS - Route Model Binding

Sun, 12 Jan 2020 00:00:00 +0000

AdonisJS was built for the NodeJS Artisans taking after the concepts of Laravel - The PHP framework for Artisans. AdonisJS did a great job porting these concepts into JavaScript, it maintains the namespace even though JavaScript does not support that, it using its own fast, easy and extendable view engine and many more, but some features of Laravel are not shipped with AdonisJS by default.

The IoC container in Laravel auto injects classes by inspection when a recognized namespace is Type Hinted. This makes route model binding easier with Laravel. In JavaScript, there is little that can be done to achieve this, so, there is a need for a custom approach to this.

AdonisJS - Using Validators with resource routes

Fri, 10 Jan 2020 00:00:00 +0000

First, install the Validator using the adonis command:

`1`	`adonis install @adonisjs/validtor`

Create a resource route

`1`	`adonis make:controller PostController --resource`

Define the route in start/route.js

1
2
3

//..
Route.resource("posts", "PostController")
//..

Now, we can make a Validator for /posts/store

This will create a validator in /app/Validators.

Migrating from WordPress to Gatsby - The Journey

Formerly, this website used to run on WordPress, the great PHP CMS. The design was made with the aid of Typography theme, I loved it!

All of the post prior to this date was written using the WordPress admin dashboard. I loved the Gutenberg Editor, it was so fluid and easy to work with. Overall my experience was great.

Programmer's Sexiness Quest

Tue, 15 Oct 2019 00:00:00 +0000

Let’s be guided, we are not getting naughty here.

Nevertheless, a programmer is a human, he has his feelings and emotions which is interesting. The direction he puts these uniquely human traits makes him more interesting - towards his code and software, of course.

I’ve been through a variety of programming languages, which always turned to be that the deeper I dive into a language, the more “aha” moment I get. It always feel like I have gotten what I wanted and I have to look no further in my quest to attract the priceless attention of my peers.

Clean Code – Rules For Name Crafting (Series)

Tue, 30 Jul 2019 00:00:00 +0000

The very first task that we do while starting to program is naming from the creation of directory to files, to classes, to functions. Name is everywhere, we cannot escape it, and we do so much of naming, we should be fulfilled if we can do it better.

Beginners do marvel at how the seniors snap out great names that fit the context to be applied. How the names are crafted seem like magic, they end up seeing themselves not so close when they see that wack name their brain could best provide.

Clean Code – Brief Review

Wed, 26 Jun 2019 00:00:00 +0000

Currently, I find my self reading Clean Code by Robert Cecil Martin, and just completed the first three chapters. I am taking my time to digest the genius work of Robert, and I see it as a need to share what could be understood in just the first 50 pages of the book.

To Robert, spending time to write the right code is an investment in the future maintenance time of that code. You can probably relate how a poorly written code has made you brainstorm for hours if not days before you could make that simple one-line change.

Running mongod service in the background – MAC OS

Wed, 26 Jun 2019 00:00:00 +0000

MongoDB ships with an easy mongod CLI command to start its server. For Linux users, there is an added level of flexibility using the Systemd service to manage foreground and background processes. To start a MongoDB server on the boot of a Linux machine, it is as easy as registering a service with systemd using:

`1`	`$ systemctl enable mongod.service`

Switching from a Linux machine to Mac, and after the successful installation of MongoDB, surely, there is a need to start the command in the background while the development process continues.

Frameworks - Not always the solution

Wed, 15 May 2019 00:00:00 +0000

Beginners do believe there is a perfect structure for setting up a project, experienced programmers know this is so far from the truth. A perfect structure is only perfect for a specific project, while project requirement varies across specifications, a perfect project setup varies across projects.

Looking further down project specifications, there are repeating patterns and procedures that make all the projects look like they are all doing the same thing. Create Read Update Delete (CRUD) was invented for this purpose, many applications are doing at least one of CRUD action, a tour around would reveal the truth about this.

Rules For Name Crafting – Part One

Wed, 15 May 2019 00:00:00 +0000

This is the first of the series – Clean Code – Rule For Name Crafting Series. In this post, we will be dealing with the first three rules stated by Robert in his Clean Code book and they are: always use intention revealing names, avoid disinformation, and make meaningful distinctions.

#1: Always Use Intention Revealing Names

To some profession, giving names that do not reveal what the item/object is about might be a norm, we have seen astroids named Iris, and a human named Mars. Imagine that you are writing an Airport Flight Management System, what could client or customer mean generally in the app?

Wed, 15 May 2019 00:00:00 +0000

Passing down functions as event handlers down to children components is a norm in the react world. It eases the communication flow, as the saying goes props down, functions up.

Things get a little bit tricky when using a React Classical component. Functions have to maintain their scope for proper interaction with their declared class properties. You might not be lucky sometimes, so there has been a couple of workaround for this.

About Me...

Mon, 01 Jan 0001 00:00:00 +0000

I’m Aleem Isiaka, a backend and cloud engineer, solutions architect with a deep commitment to building resilient, scalable systems that drive measurable impact. With nearly a decade of experience across backend development, infrastructure, and distributed systems, I specialize in architecting solutions that merge reliability, performance, and automation with end user experience.

My work sits at the intersection of site reliability engineering, cloud-native tooling, and scalable infrastructures, with hands-on contributions spanning Kubernetes, observability platforms, and infrastructure-as-code. From architecting high-throughput systems to reducing latency and improving uptime, I thrive in environments where scale and fault-tolerance are not just nice-to-haves but core requirements.

The C Programming Language

Mon, 01 Jan 0001 00:00:00 +0000

C is a general-purpose programming language and is closely associated with Unix systems where it was developed. It is a machine independent language and often time called system programming language due to its usefulness in writing compilers and operating systems.

C picked up ideas from BCPL developed by Martin Richards who took ideas from B developed by Ken Thompson in 1970 for the first UNIX systems using DEC PDP-7.

Both B and BCPL are untyped languages, whereas C has fundamental types like characters, integers, floating-point numbers, etc., and derived data types like pointers, arrays, structures, pointers, and unions. C has expressions and operands, where any expression can be a statement.
