No-Code MVP — Build Your Idea Without Coding

Is it possible to be an entrepreneur and NOT know how to code?


You have a great idea for a product / platform / app / startup that you cannot wait to launch and sell. But before you do that, you’d have to test your idea through the minimum viable version of your product.


And to build your MVP (minimum viable product), you’d need to code, right? Wrong!


You don’t need coding chops to build your MVP. And neither do you need to beg engineers to become technical co-founders.


With a no-code MVP, you can validate your idea sooner and test if it has the potential to succeed. Let’s explore how you can convert your business idea into MVP without writing a single line of code.


But first, what exactly is an MVP?


MVP or minimum viable product is the first version of the product for your target audience. It essentially means the most basic version of your product you can get out for the audience.


The idea here is to focus only on enough features with which you can test your concept’s workability and then work on its continuous development based on user feedback.

Javascript Fun: Hacking Google Chrome’s T-rex Game

image

All of us like to have an extra edge while playing games (i mean cheat codes :P ). Most games have such codes that allow you to alter the gaming experience while many other games find it illegal to use such hacks.

But, have you thought about how all this works?

Let us understand it by actually ‘HACKING’ one of the simplest games out there — the T-rex runner.

For those who do not know, it is a side scrolling runner game that appears on the ‘No Internet’ screen of Google Chrome.

This 8-bit-type game features a tiny t-rex which runs through a desert. You have to avoid the t-rex from hitting the obstacles like cacti etc. Believe me, it is simple but addictive.

We will be using simple Javascript commands to tweak the game for fun!

Sounds cool? Let's do it.

1. Getting into the game’s console


First, disconnect your device from the internet and open Google Chrome. Enter any url and you will see the no internet screen with a t-rex dino.

If you want to stay online for some reason, simply enter ‘chrome://dino’ in the address bar.

Now, right click inside the window and click the Inspect option from the menu. Alternatively, you can use the shortcut key combination — Ctrl+Shift+I.

In the side panel which opens, you will be able to see the source code of the game. Next, click the console tab. This is the place where we will run our simple Javascript code to alter the game.

Как добавлять и читать формулы Excel на Java

Making Simple Mouse Clicking Game: HTML5 & JS (Beginners)

The best of learning something is by implementing it especially when you are a beginner. In this post, I am sharing how I made a simple mouse clicking game using HTML5 and JS. It will help you understand the basic concepts of Javascript such as event handling and counters.

Before I start anything, let me be very clear about the fact that this post has almost nothing for the people who already know the basics of Javascript. I am writing this out just from the beginner’s point of view.

So let's get started!

The Aim


In a really simple sense, we are going to make a game which counts the number of clicks you do in a set time interval and calculates your clicking speed. We will show the clicking speed and total clicks at the end of the game.

The UI will be absolutely basic. There are no shimmering graphics; its just one button and the counters.

Here's the first look.

image

The Logic


As mentioned, we need to count the number of clicks made by the user. So, we will add an Event Listener using Javascript to check if the mouse button is clicked inside the button area.

And, to save the count, we will use a counter whose value increases on every mouse click event. There will be another counter for time. The default time period will be 10s.

The final score will be calculated using the total number of clicks divided by the time and we will display it at the end of the game.

Before we move the actual code, I want to give a small acknowledgement to a tool called Click Test which inspired this simple game I made for learning purpose.

Creating the Interface


Let us begin by creating a simple page with a headline, a box for counters and a button inside it for clicking. I have used the basic red color for everything but you are free to show your CSS skills and make it fancier.

Next, we need to implement the counter for clicks on the button. A simple JS snippet provided does the magic for this.

Floating — point issue and one of the solutions in Python

They say: ‘Brevity is the soul of wit’, so let’s get started.

Introduction

When I began to learn Python I came across a very curious subject, namely Real Numbers. It was about the mantissa, the exponent, and other details like the storage of bits in computers.
image

It turns out that computers operate integer numbers easily, but real numbers are more complicated.

Nature of the problem

Because of the essence of the floating — point numbers their processing has no absolute accuracy. It seemed to me nonsense that computers can’t compute precise values of ordinary two real numbers at least. How’s this possible? Yeah, actually, a computer programme isn’t able to add just two numbers without discrepancy.

x = 0.1
y = 0.2
print(x + y)  # 0.30000000000000004 


Well, close enough you might say. Who cares about 17th decimal sign. But imagine you need to compute twenty numbers not two as in the example. Think about the error rises exponentially.
Tell me about libraries like a NumPy. They don’t solve the problem as well.

Short History and Evolution of Online Sextortion



Online frauds are quickly gaining traction among cybercriminals. The primary reason is that manipulating humans is much easier than exploiting software or hardware flaws. Although the success rate of Internet scams is low compared to the efficiency of sure-shot attacks relying on zero-day vulnerabilities, the simplicity of pulling them off is a lure that eclipses all the drawbacks.

A hoax dubbed sextortion (sex + extortion) is a dynamically growing vector of this abuse. Having debuted in 2018, it acts upon a victim’s natural commitment to avoiding embarrassment.

This technique mostly involves an email saying that a hacker has infiltrated the recipient’s device and captured a webcam video of the person watching adult videos. The bluffer threatens to upload this footage to a publicly accessible site. To prevent this from happening, the user is instructed to pay a ransom.

There are several mainstream techniques in sextortion scammers’ portfolios. Whereas they all follow basically the same logic, the themes of these fraudulent messages vary. Here is a summary of all these tricks known to date.

Подсчет LT и график Rolling Retention

Всем привет.

Мне понадобилось на работе подсчитать LT и построить график Rolling Retention. После небольшого исследования, я поняла, что тема является насущной и неплохо было бы написать обо всех шагах, дабы кому-то это обязательно пригодится.

В основном, я опиралась на пример от Марии Мансуровой и библиотеку, написанную Darshil Desai и добавила кое-что свое.
https://nbviewer.jupyter.org/github/miptgirl/misc_code/blob/master/webinar_case.ipynb
medium.com/analytics-vidhya/user-retention-in-python-8c33fa5766b6

Теория по подсчету LT хорошо написана здесь и здесь.

Итак, я выбрала следующие пути:

  1. Я взяла когорты пользователей — зарегистрировавшихся с 1 Января по 31 Января 2020, c 1 Февраля по 29 Февраля и т.д. вплоть до Апреля. Посчитала LT в месяцах, предварительно выкинув пользователей 'проживших' один день. То есть внесших депозит и больше не появляющихся в какой-либо день за полгода.
  2. Я брала всех пользователей, даже тех кто прожил 1 день и рассчитывала когорты по неделям среди всех, зарегистрировавшихся с 1 января по 29 февраля 2020 года.

Я строила Rolling Retention. Его основное отличие от классического Retention в том, что в данном случае, смотрится первая дата активности и последняя, и считается, что пользователь заходил на сайт каждый месяц/неделю/день.

Итак, 1-ый способ


Для начала введем код в ячейку в Jupyter Notebook и установим следующую библиотеку:

Строчки, точки и JavaScript

На своих проектах мы часто сталкиваемся с простыми, но интересными задачами. Мы их складируем и даем джунам/стажерам для ускорения обучения. Одной из таких задач стала задача с размещением одной или более точек между букв внутри слова всеми возможными способами.

Например программа на вход получает 'abc'

> abc
['abc', 'a.bc', 'ab.c', 'a.b.c']

Ее можно решить несколькими способами, но разобрать я хочу 2 из них.

Вы могли заметить, что размещение точек очень напоминает бинарные числа
