Shamelessly stealing an idea from @jacksonfall and prompting GPT-4 to help me build a profitable business.

I'm going to start with the same prompt and do whatever it asks me to.

Let's goooooooo

Alright so the approach here is to find a product or service with high demand and low supply using a website like @junglescout or @GoogleTrends

On Google trends, the term "chat GPT" is exploding in popularity so I asked HustleGPT to suggest products related to that.

#gpt4 Image
@junglescout @GoogleTrends Top ideas generated by the bot 🤖

- AI-related books
- Ergonomic keyboards
- High-quality microphones
- Webcams

It also suggested digital products and I liked that more so I asked it to elaborate.

The answer? Chat bot scripts. That sounds easy enough 😅 Image

#willwritesandcodes #100DaysofCode #Day31

Uninstalled and reinstalled @ProgrammingHero again, did the exam for #Cpp course, and it still crashed at the end.


It could be my phone. I'll have to try installing it on another device. Still a bummer screenshot of the error message as programming hero app cras
Also resinstalled the very different app, @Prghub, which has much shorter courses and as a result felt deceptive about how much you were learning. I haven't uses it in over a year for sure. They have a bunch of new courses. I'll try some-I don't know if I'll keep at it w this app
#willwritesandcodes #100DaysofWriting #Day23-#Day27, need to keep track of how much I write and where. I kind of write a lot, but not always towards the goals I want to write toward. So I'm writing this tweet to stand in for missing those days' record while noting that I do write

#willwritesandcodes #100DaysOfCode #Day30

Today was a great family day-

also studied some

Looked over my #Cpp cards

2 Docker lessons
4 #CSS lessons (next #Sass)
pseudocode for binary search algorithm

closely read #Knuth's flowchart for #ArtofComputerProgramming
@wildlearnerapp's #React course has taught me more so far than at least one other online course, if not two others.
My strategy is #repeatedexposure - the more I get aquainted with a lot of the concepts, the easier I find it to engage in coding itself, its concepts, syntax, & logic --- especially since I have such a hard time getting to sit down to actually code, given my job and family life.

#willwritesandcodes #100DaysofCode #Day29 (actual)

This is a throwback to my first javascript *script,* useBash.

I just love #bash

Anyways, today... Image
Today I haven't done nearly enough; but I went over my #JavaScript Interview Question flashcards (& the 1st #Cpp one)

I also discovered @wildlearnerapp !! which is very schnazzy looking & has good quizzing so far (but where is the C++ course?)

I *love* discovering new resources
Also, #Perl? watched a couple videos on Perl.

My learning journey is vast, immersive, and cyclical. If I don't finish something right away, or if I start something new, I almost always cycle back to the old ones. I feel I have learned a lot this way, for better or worse.

📊 Hey Folks

✍ So Day - 6 on #powerbi 🚀

⚠ Today I Made a Awesome #America Retail Analysis Dashboard

#willwritesandcodes #100DaysofCode #Day19

Today I did several @enkidevs workouts on #CSS and #interviewprep, finally actually finished the #HowToProgram video on Python Modules, typing up a #python program from the video which I hope to record an audio code walkthrough for.
Hoping to get more done today still. Overall, I've been pretty productive, due in part to using the #forestapp for #focus.
I've heard a number of people talk about how important it is to get used to reading other people's code, actually understanding it, and talking about it, so if I start doing these walkthroughs it will be to practice those skills.

#willwritesandcodes #100DaysofCode #Day19

I should spend more time going over #Perlisisms. I'm sure some of them are outdated; a number of them seem worth dwelling on.
Today I did several @enkidevs workouts, and at least one @GrasshopperApp lesson.

I find it is frustratingly easier to study than to actually sit down and code. Is this procrastination? Why is typing out lines on the computer harder than reading etc?
Probably fear of failure mixed with the sense of being so slow, already bypassed by others, that I feel walking in the right direction is almost - a waste of time?

I've been on both sides of an Interview table and have experience over 50+ interviews.

Here are some 8 Tips about cracking your Technical Interviews 🧵👇

#100DaysOfCode #Interviews
1. Ask Questions:

You will be intentionally given a vague question with vague inputs.

You are expected to ask clarifying question and have clear understanding of requirements before jumping into solution.

Don't assume anything !!
2. Improve Solution Overtime

You're not expected to come up with optimised solution in one go. First come up with brute force and then eventually try to optimize it.

Interviewers usually give some hint about optimised solution. Don't expect it for obvious ones.

Generator function* in JavaScript:

A thread 🧵

#100DaysOfCode #javascript #Angular #reactjs #devbubble
In JavaScript, generator functions are a special type of function that allows you to use the yield keyword to pause and resume the execution of the function.

#100DaysOfCode #NodeJS #CodeLife
They allow you to create iterators, which are objects that can be used to iterate over a sequence of values.

A generator function is defined using the function* keyword and can be invoked using the yield keyword.

Memoization: Using Proxy in JavaScript

#100DaysOfCode #javascript #rarely_used #devbubble
Memoization is a technique used to optimize the performance of a function by caching its results for a given set of inputs.

#100DaysOfCode #reactjs #Angular #NodeJS
The idea is that if a function is called multiple times with the same input, it's more efficient to return the cached result instead of re-computing the result each time.

Data virtualization: With Proxies in JavaScript.

A thread 🧵

#100DaysOfCode #javascript #rarely_used #devbubble
Data virtualization using Proxies in JavaScript refers to the ability to create virtualized data structures, such as virtualized arrays, that load their data on demand rather than loading all data at once.

#100DaysOfCode #ReactJS #Angular
This can be useful for improving the performance of an application when working with large data sets.

In this Eg., we create a VirtualArray class that takes in two args- the length of the array & a loader function.

Wowwwwww today is a day to celebrate! My blog is finally live and the first post is CRAZY nice 😱🔥



#javascript #nodejs #learning #blogpost #tutorial #websockets #socketio #diy #100daysofcode Image
I've been creating videos on my youtube channel that you rarely will see in another place on the internet 🤩

You'll find there subjects like Recreating @nodejs from scratch, Web APIs and recreating web protocols such as the Web Socket using JS with no frameworks, etc

And others, which are amazing experiments, such as recreating a code coverage tool from scratch and how to process terabytes of data using JavaScript

If you search about those subjects you'd reach out to my videos but why not have them as blog posts as well?

Sabia que é possível usar JavaScript para interpretar variáveis do bash direto do terminal? 🤯🔥


#javascript #nodejs #js #bash #devtips #100daysofcode #node #childprocess #tutorial Image
Estava produzindo uma super aula do meu curso de Node.js Streams (em inglês), ensinando sobre como paralelizar o processamento de arquivos usando Node.js

A ideia é subir um processo para cada arquivo, e cada processo filtra os usuários que possuem o email em dominio gmail

Só que eu automatizei a validação para verificar que todos os itens foram processados e enviados para um arquivo de saida

Então primeiro fui lá e usei o `grep` para filtrar o texto do arquivo e o `wc -l`, para obter a quantidade de linhas.

WeakMap in JavaScript

A thread 🧵

#100DaysOfCode #javascript #rarely_used
A WeakMap is a map that holds weak references to its keys.

This means that the keys are eligible for garbage collection if there are no other references to them.

This feature can be useful for implementing caches or other similar data structures.

#reactjs #Angular #NodeJS #js
A WeakMap is a special kind of map where keys must be objects and the map doesn't prevent garbage collection of its keys.

You can think of a WeakMap as a map that doesn't "own" its keys, and therefore doesn't keep them alive.
