The Top 5 Mathematical Concepts Every Programmer Needs to Know
Using math to write efficient code in any language
Programmers design, build, test, and maintain software. Employ cases and personal preferences determine the programming languages we use throughout development. Mobile app developers use JavaScript or Dart. Some programmers design performance-first software in C/C++.
A generic source code includes language-specific grammar, pre-implemented function calls, mathematical operators, and control statements. Some mathematical principles assist us enhance our programming and problem-solving skills.
We all use basic mathematical concepts like formulas and relational operators (aka comparison operators) in programming in our daily lives. Beyond these mathematical syntaxes, we'll see discrete math topics. This narrative explains key math topics programmers must know. Master these ideas to produce clean and efficient software code.
Expressions in mathematics and built-in mathematical functions
A source code can only contain a mathematical algorithm or prebuilt API functions. We develop source code between these two ends. If you create code to fetch JSON data from a RESTful service, you'll invoke an HTTP client and won't conduct any math. If you write a function to compute the circle's area, you conduct the math there.
When your source code gets more mathematical, you'll need to use mathematical functions. Every programming language has a math module and syntactical operators. Good programmers always consider code readability, so we should learn to write readable mathematical expressions.
Linux utilizes clear math expressions.
Inbuilt max and min functions can minimize verbose if statements.
How can we compute the number of pages needed to display known data? In such instances, the ceil function is often utilized.
import math as m
results = 102
items_per_page = 10
pages = m.ceil(results / items_per_page)
print(pages)Learn to write clear, concise math expressions.
Combinatorics in Algorithm Design
Combinatorics theory counts, selects, and arranges numbers or objects. First, consider these programming-related questions. Four-digit PIN security? what options exist? What if the PIN has a prefix? How to locate all decimal number pairs?
Combinatorics questions. Software engineering jobs often require counting items. Combinatorics counts elements without counting them one by one or through other verbose approaches, therefore it enables us to offer minimum and efficient solutions to real-world situations. Combinatorics helps us make reliable decision tests without missing edge cases. Write a program to see if three inputs form a triangle. This is a question I commonly ask in software engineering interviews.
Graph theory is a subfield of combinatorics. Graph theory is used in computerized road maps and social media apps.
Logarithms and Geometry Understanding
Geometry studies shapes, angles, and sizes. Cartesian geometry involves representing geometric objects in multidimensional planes. Geometry is useful for programming. Cartesian geometry is useful for vector graphics, game development, and low-level computer graphics. We can simply work with 2D and 3D arrays as plane axes.
GetWindowRect is a Windows GUI SDK geometric object.
High-level GUI SDKs and libraries use geometric notions like coordinates, dimensions, and forms, therefore knowing geometry speeds up work with computer graphics APIs.
How does exponentiation's inverse function work? Logarithm is exponentiation's inverse function. Logarithm helps programmers find efficient algorithms and solve calculations. Writing efficient code involves finding algorithms with logarithmic temporal complexity. Programmers prefer binary search (O(log n)) over linear search (O(n)). Git source specifies O(log n):
Logarithms aid with programming math. Metas Watchman uses a logarithmic utility function to find the next power of two.
Employing Mathematical Data Structures
Programmers must know data structures to develop clean, efficient code. Stack, queue, and hashmap are computer science basics. Sets and graphs are discrete arithmetic data structures. Most computer languages include a set structure to hold distinct data entries. In most computer languages, graphs can be represented using neighboring lists or objects.
Using sets as deduped lists is powerful because set implementations allow iterators. Instead of a list (or array), store WebSocket connections in a set.
Most interviewers ask graph theory questions, yet current software engineers don't practice algorithms. Graph theory challenges become obligatory in IT firm interviews.
Recognizing Applications of Recursion
A function in programming isolates input(s) and output(s) (s). Programming functions may have originated from mathematical function theories. Programming and math functions are different but similar. Both function types accept input and return value.
Recursion involves calling the same function inside another function. In its implementation, you'll call the Fibonacci sequence. Recursion solves divide-and-conquer software engineering difficulties and avoids code repetition. I recently built the following recursive Dart code to render a Flutter multi-depth expanding list UI:
Recursion is not the natural linear way to solve problems, hence thinking recursively is difficult. Everything becomes clear when a mathematical function definition includes a base case and recursive call.
Conclusion
Every codebase uses arithmetic operators, relational operators, and expressions. To build mathematical expressions, we typically employ log, ceil, floor, min, max, etc. Combinatorics, geometry, data structures, and recursion help implement algorithms. Unless you operate in a pure mathematical domain, you may not use calculus, limits, and other complex math in daily programming (i.e., a game engine). These principles are fundamental for daily programming activities.
Master the above math fundamentals to build clean, efficient code.

Looker Studio Pro is now generally available, according to Google.
Great News about the new Google Business Intelligence Solution
Google has renamed Data Studio to Looker Studio and Looker Studio Pro.
Now, Google releases Looker Studio Pro. Similar to the move from Data Studio to Looker Studio, Looker Studio Pro is basically what Looker was previously, but both solutions will merge. Google says the Pro edition will acquire new enterprise management features, team collaboration capabilities, and SLAs.
In addition to Google's announcements and sales methods, additional features include:
Looker Studio assets can now have organizational ownership. Customers can link Looker Studio to a Google Cloud project and migrate existing assets once. This provides:
Your users' created Looker Studio assets are all kept in a Google Cloud project.
When the users who own assets leave your organization, the assets won't be removed.
Using IAM, you may provide each Looker Studio asset in your company project-level permissions.
Other Cloud services can access Looker Studio assets that are owned by a Google Cloud project.
Looker Studio Pro clients may now manage report and data source access at scale using team workspaces.
Google announcing these features for the pro version is fascinating. Both products will likely converge, but Google may only release many features in the premium version in the future. Microsoft with Power BI and its free and premium variants already achieves this.

Has anyone noticed what an absolute shitshow LinkedIn is?
After viewing its insanity, I had to leave this platform.
I joined LinkedIn recently. That's how I aim to increase my readership and gain recognition. LinkedIn's premise appealed to me: a Facebook-like platform for professional networking.
I don't use Facebook since it's full of propaganda. It seems like a professional, apolitical space, right?
I expected people to:
be more formal and respectful than on Facebook.
Talk about the inclusiveness of the workplace. Studies consistently demonstrate that inclusive, progressive workplaces outperform those that adhere to established practices.
Talk about business in their industry. Yep. I wanted to read articles with advice on how to write better and reach a wider audience.
Oh, sh*t. I hadn't anticipated that.
After posting and reading about inclusivity and pro-choice, I was startled by how many professionals acted unprofessionally. I've seen:
Men have approached me in the DMs in a really aggressive manner. Yikes. huge yikes Not at all professional.
I've heard pro-choice women referred to as infant killers by many people. If I were the CEO of a company and I witnessed one of my employees acting that poorly, I would immediately fire them.
Many posts are anti-LGBTQIA+, as I've noticed. a lot, like, a lot. Some are subtly stating that the world doesn't need to know, while others are openly making fun of transgender persons like myself.
Several medical professionals were posting explicitly racist comments. Even if you are as white as a sheet like me, you should be alarmed by this. Who's to guarantee a patient who is black won't unintentionally die?
I won't even get into how many men in STEM I observed pushing for the exclusion of women from their fields. I shouldn't be surprised considering the majority of those men I've encountered have a passionate dislike for women, but goddamn, dude.
Many people appear entirely too at ease displaying their bigotry on their professional profiles.
As a white female, I'm always shocked by people's open hostility. Professional environments are very important.
I don't know if this is still true (people seem too politicized to care), but if I heard many of these statements in person, I'd suppose they feel ashamed. Really.
Are you not ashamed of being so mean? Are you so weak that competing with others terrifies you? Isn't this embarrassing?
LinkedIn isn't great at censoring offensive comments. These people aren't getting warnings. So they were safe while others were unsafe.
The CEO in me would want to know if I had placed a bigot on my staff.
I always wondered if people's employers knew about their online behavior. If they know how horrible they appear, they don't care.
As a manager, I was picky about hiring. Obviously. In most industries, it costs $1,000 or more to hire a full-time employee, so be sure it pays off.
Companies that embrace diversity and tolerance (and are intolerant of intolerance) are more profitable, likely to recruit top personnel, and successful.
People avoid businesses that alienate them. That's why I don't eat at Chic-Fil-A and why folks avoid MyPillow. Being inclusive is good business.
CEOs are harmed by online bigots. Image is an issue. If you're a business owner, you can fire staff who don't help you.
On the one hand, I'm delighted it makes it simpler to identify those with whom not to do business.
Don’t get me wrong. I'm glad I know who to avoid when hiring, getting references, or searching for a job. When people are bad, it saves me time.
What's up with professionalism?
Really. I need to know. I've crossed the boundary between acceptable and unacceptable behavior, but never on a professional platform. I got in trouble for not wearing bras even though it's not part of my gender expression.
If I behaved like that at my last two office jobs, my supervisors would have fired me immediately. Some of the behavior I've seen is so outrageous, I can't believe these people have employment. Some are even leaders.
Like…how? Is hatred now normalized?
Please pay attention whether you're seeking for a job or even simply a side gig.
Do not add to the tragedy that LinkedIn comments can be, or at least don't make uninformed comments. Even if you weren't banned, the site may still bite you.
Recruiters can and do look at your activity. Your writing goes on your résumé. The wrong comment might lose you a job.
Recruiters and CEOs might reject candidates whose principles contradict with their corporate culture. Bigotry will get you banned from many companies, especially if others report you.
If you want a high-paying job, avoid being a LinkedIn asshole. People care even if you think no one does. Before speaking, ponder. Is this how you want to be perceived?
Better advice:
If your politics might turn off an employer, stop posting about them online and ask yourself why you hold such objectionable ideas.

This is how I started my Twitter account.
My 12-day results look good.
Twitter seemed for old people and politicians.
I thought the platform would die soon like Facebook.
The platform's growth stalled around 300m users between 2015 and 2019.
In 2020, Twitter grew and now has almost 400m users.
Niharikaa Kaur Sodhi built a business on Twitter while I was away, despite its low popularity.
When I read about the success of Twitter users in the past 2 years, I created an account and a 3-month strategy.
I'll see if it's worth starting Twitter in 2022.
Late or perfect? I'll update you. Track my Twitter growth. You can find me here.
My Twitter Strategy
My Twitter goal is to build a community and recruit members for Mindful Monday.
I believe mindfulness is the only way to solve problems like poverty, inequality, and the climate crisis.
The power of mindfulness is my mission.
Mindful Monday is your weekly reminder to live in the present moment. I send mindfulness tips every Monday.
My Twitter profile promotes Mindful Monday and encourages people to join.
What I paid attention to:
I designed a brand-appropriate header to promote Mindful Monday.
Choose a profile picture. People want to know who you are.
I added my name as I do on Medium, Instagram, and emails. To stand out and be easily recognized, add an emoji if appropriate. Add what you want to be known for, such as Health Coach, Writer, or Newsletter.
People follow successful, trustworthy people. Describe any results you have. This could be views, followers, subscribers, or major news outlets. Create!
Tell readers what they'll get by following you. Can you help?
Add CTA to your profile. Your Twitter account's purpose. Give instructions. I placed my sign-up link next to the CTA to promote Mindful Monday. Josh Spector recommended this. (Thanks! Bonus tip: If you don't want the category to show in your profile, e.g. Entrepreneur, go to edit profile, edit professional profile, and choose 'Other'
Here's my Twitter:
I'm no expert, but I tried. Please share any additional Twitter tips and suggestions in the comments.
To hide your Revue newsletter subscriber count:
Join Revue. Select 'Hide Subscriber Count' in Account settings > Settings > Subscriber Count. Voila!
How frequently should you tweet?
1 to 20 Tweets per day, but consistency is key.
Stick to a daily tweet limit. Start with less and be consistent than the opposite.
I tweet 3 times per day. That's my comfort zone. Larger accounts tweet 5–7 times daily.
Do what works for you and that is the right amount.
Twitter is a long-term game, so plan your tweets for a year.
How to Batch Your Tweets?
Sunday batchs.
Sunday evenings take me 1.5 hours to create all my tweets for the week.
Use a word document and write down your posts. Podcasts, books, my own articles inspire me.
When I have a good idea or see a catchy Tweet, I take a screenshot.
To not copy but adapt.
Two pillars support my content:
(90% ~ 29 tweets per week) Inspirational quotes, mindfulness tips, zen stories, mistakes, myths, book recommendations, etc.
(10% 2 tweets per week) I share how I grow Mindful Monday with readers. This pillar promotes MM and behind-the-scenes content.
Second, I schedule all my Tweets using TweetDeck. I tweet at 7 a.m., 5 p.m., and 6 p.m.
Include Twitter Threads in your content strategy
Tweets are blog posts. In your first tweet, you include a headline, then tweet your content.
That’s how you create a series of connected Tweets.
What’s the point? You have more room to convince your reader you're an expert.
Add a call-to-action to your thread.
Follow for more like this
Newsletter signup (share your link)
Ask for retweet
One thread per week is my goal.
I'll schedule threads with Typefully. In the free version, you can schedule one Tweet, but that's fine.
Pin a thread to the top of your profile if it leads to your newsletter. So new readers see your highest-converting content first.
Tweet Medium posts
I also tweet Medium articles.
I schedule 1 weekly repost for 5 weeks after each publication. I share the same article daily for 5 weeks.
Every time I tweet, I include a different article quote, so even if the link is the same, the quote adds value.
Engage Other Experts
When you first create your account, few people will see it. Normal.
If you comment on other industry accounts, you can reach their large audience.
First, you need 50 to 100 followers. Here's my beginner tip.
15 minutes a day or when I have downtime, I comment on bigger accounts in my niche.
My 12-Day Results
Now let's look at the first data.
I had 32 followers on March 29. 12 followers in 11 days. I have 52 now.
Not huge, but growing rapidly.
Let's examine impressions/views.
As a newbie, I gained 4,300 impressions/views in 12 days. On Medium, I got fewer views.
The 1,6k impressions per day spike comes from a larger account I mentioned the day before. First, I was shocked to see the spike and unsure of its origin.
These results are promising given the effort required to be consistent on Twitter.
Let's see how my journey progresses. I'll keep you posted.
Tweeters, Does this content strategy make sense? What's wrong? Comment below.
Let's support each other on Twitter. Here's me.
Which Twitter strategy works for you in 2022?

Activating Your Vagus Nerve
11 science-backed ways to improve health, happiness, healing, relaxation, and mental clarity.
Vagus nerve is the main parasympathetic nervous system component.
It helps us rest and digest by slowing and stabilizing a resting heart rate, slowing and stabilizing the breath, promoting digestion, improving recovery and healing times, producing saliva, releasing endorphins and hormones like dopamine, oxytocin, and serotonin, and boosting the immune, digestive, and cardiovascular systems.
The vagus nerve sends anti-inflammatory signals to other parts of the body and is located behind the tongue, in the throat, neck, heart, lungs, abdomen, and brainstem.
Vagus means wandering in Latin. So, it's bold.
Here are 11 proven ways to boost health, happiness, and the vagus nerve.
1. Extend
“Yoga stimulates different nerves in your body, especially the vagus nerve that carries information from the brain to most of the body’s major organs, slows everything down and allows self-regulation. It’s the nerve that is associated with the parasympathetic system and emotions like love, joy, and compassion.” — Deepak Chopra
Stretching doesn't require a yoga background.
Listen to your body and ease into simple poses. This connects the mind and body.
If you're new to yoga or don't have access to an in-person class, try Yoga with Adrienne. Over 600 YouTube videos give her plenty of material.
2. Inhale
Because inhaling and exhaling activate the autonomic nervous system, we can breathe to relax.
Exhaling activates the parasympathetic nervous system (rest and digest). One inhales stress, the other exhales it.
So, faster or more intense breathing increases stress. Slower breathing relaxes us.
Breathe slowly, smoothly, and less.
Rhythmic breathing helps me relax.
What to do is as follows:
1. Take 4 smooth, forceless nose breaths.
2. Exhale smoothly and forcefully for 4 seconds
3. Don't pause at the inhale or exhale.
4. Continue for 5 minutes/40 breaths
5. Hold your breath as long as comfortable.
6. Breathe normally.
If four seconds is too long, try breathing in and out for two seconds, or in and out for three seconds, until your breath naturally relaxes. Once calmer, extend your breath.
Any consistent rhythm without force is good. Your heart will follow your lead and become coherent.
3. Chant/Hum
Singing, chanting, or humming activate the vagus nerve through the back of the throat.
Humming emits nitric oxide.
Nitric oxide improves blood circulation, blood flow, heart health, and blood pressure.
Antiviral, antibacterial, anti-inflammatory, antioxidant, and antimicrobial properties kill viruses and bacteria in the nose and throat.
Gargling water stimulates the vagus nerve.
Simple ways to heal, boost energy, and boost mood are often the healthiest. They're free and can be done anywhere.
4. Have more fun
Laughing stimulates the throat muscles, activating the vagus nerve. What's not to like? It releases dopamine.
Take time to enjoy life. Maybe it's a book, podcast, movie, socializing with friends, or laughing yoga.
Follow your bliss, as Joseph Campbell says.
Laugh at yourself
Actually. Really.
Gagging activates vagus nerve-connected muscles. Some doctors use the gag reflex to test the vagus nerve.
Grossness isn't required. While brushing, gag quickly. My girlfriend's brother always does it.
I'm done brushing when I gag, he says.
6. Take in the outdoors
Nature relaxes body and mind. Better if you can walk barefoot.
Earthing is associated with hippies dancing in daisies.
Science now supports hippies.
7. Enter some chilly water.
The diving reflex activates the vagus nerve when exposed to cold water.
The diving reflex involves holding your breath in cold water. Cold showers work best.
Within minutes of being in cold water, parasympathetic nervous system activity, which calms the body, increases.
8. Workout
Exercise increases dopamine, blood circulation, and breathing. So we feel energized, calm, and well-rested.
After resting, the parasympathetic nervous system engages.
It's worth waiting for, though.
9. Play music with brainwaves
Brainwave music harmonizes brainwave activity, boosts productivity and mental clarity, and promotes peace and relaxation by stimulating the vagus nerve.
Simply play a song.
My favorite.
10. Make gentle eyes
Eyes, like breath, often reflect inner state. Sharp, dilated, focused eyes indicate alertness.
Soft, open eyes reflect relaxation and ease. Soft eyes relax the nervous system.
This practice reduces stress, anxiety, and body tension. It's a quick and effective way to enter a calm, peaceful state.
Wild animals can be hunted one minute and graze the next.
Put it into action:
Relax while seated.
Gaze at a distant object
Use peripheral vision while looking straight ahead
Without moving your eyes, look up and down. Connect side spaces to your vision.
Focus on everything as your eyes soften.
Keep breathing
Stay as long as you like
11. Be intimate
We kiss, moan, and breathe deeper during love. We get dopamine, oxytocin, serotonin, and vagus nerve stimulation.
Why not?
To sum up
Here are 11 vagus nerve resets:
Stretch
Breathe
Hum/Chant
More humor
Amuse yourself
Spend time outdoors
Leap into chilly water
Exercise
Play music with brainwaves.
Make gentle eyes.
Be intimate
If these words have inspired you, try my favorite breathwork technique. Combining breathing, chanting, and brainwave music. Win-win-win :)

What Happened After I Posted an AI-Generated Post on My Website
This could cost you.
Content creators may have heard about Google's "Helpful content upgrade."
This change is another Google effort to remove low-quality, repetitive, and AI-generated content.
Why should content creators care?
Because too much content manipulates search results.
My experience includes the following.
Website admins seek high-quality guest posts from me. They send me AI-generated text after I say "yes." My readers are irrelevant. Backlinks are needed.
Companies copy high-ranking content to boost their Google rankings. Unfortunately, it's common.
What does this content offer?
Nothing.
Despite Google's updates and efforts to clean search results, webmasters create manipulative content.
As a marketer, I knew about AI-powered content generation tools. However, I've never tried them.
I use old-fashioned content creation methods to grow my website from 0 to 3,000 monthly views in one year.
Last year, I launched a niche website.
I do keyword research, analyze search intent and competitors' content, write an article, proofread it, and then optimize it.
This strategy is time-consuming.
But it yields results!
Here's proof from Google Analytics:
Proven strategies yield promising results.
To validate my assumptions and find new strategies, I run many experiments.
I tested an AI-powered content generator.
I used a tool to write this Google-optimized article about SEO for startups.
I wanted to analyze AI-generated content's Google performance.
Here are the outcomes of my test.
First, quality.
I dislike "meh" content. I expect articles to answer my questions. If not, I've wasted my time.
My essays usually include research, personal anecdotes, and what I accomplished and achieved.
AI-generated articles aren't as good because they lack individuality.
Read my AI-generated article about startup SEO to see what I mean.
It's dry and shallow, IMO.
It seems robotic.
I'd use quotes and personal experience to show how SEO for startups is different.
My article paraphrases top-ranked articles on a certain topic.
It's readable but useless. Similar articles abound online. Why read it?
AI-generated content is low-quality.
Let me show you how this content ranks on Google.
The Google Search Console report shows impressions, clicks, and average position.
Low numbers.
No one opens the 5th Google search result page to read the article. Too far!
You may say the new article will improve.
Marketing-wise, I doubt it.
This article is shorter and less comprehensive than top-ranking pages. It's unlikely to win because of this.
AI-generated content's terrible reality.
I'll compare how this content I wrote for readers and SEO performs.
Both the AI and my article are fresh, but trends are emerging.
My article's CTR and average position are higher.
I spent a week researching and producing that piece, unlike AI-generated content. My expert perspective and unique consequences make it interesting to read.
Human-made.
In summary
No content generator can duplicate a human's tone, writing style, or creativity. Artificial content is always inferior.
Not "bad," but inferior.
Demand for content production tools will rise despite Google's efforts to eradicate thin content.
Most won't spend hours producing link-building articles. Costly.
As guest and sponsored posts, artificial content will thrive.
Before accepting a new arrangement, content creators and website owners should consider this.
