How Custom Mobile App Development, Help to Make Your Business More Successful
Tags: mobileapp, customapplication, custommobileapp
Published: 2022-04-12 13:08:15

The number of applications in the app store increases day-by-day. Unfortunately, competition is also getting tougher and tougher. If you are an entrepreneur and running a business, you should take the right steps to make your business more successful. You need to be very smart in your marketing strategies, come up with creative ideas and promote your product in the right way.
To stay ahead of the curve, you need to be very creative. The same applies to your mobile application development. You need to make sure that your mobile app is designed in a way that people love to use it.

Mobile apps have changed the way that we interact with our smartphones. They are the new interface to many of our favorite products and services. The rise of mobile is driven by faster internet connections, more sophisticated processors, and a shift in consumer behavior.

With [custom mobile app development](https://www.techmango.net/mobile-app-development-company) organizations can build their own apps that are tailored to their customers needs and they can be integrated into other platforms like social media or wearable/the Internet-of-Things devices.

Custom mobile app development is changing the way that we use technology today.

Published: 2022-04-12 13:04:30

## Request
Request is a simple tool that allows user to test their API with web interface.

Request is written with tauri and vite vanilla typescript and its fully open-source!

- Repository: https://github.com/aiocat/request

You can contribute to the project if you want to.

## Features
- Save, load, delete requests
- View headers
- Generate request code
- Send request with headers
- Filter requests

### Why?
Lots of postman (like) program already exists. But they are really confusing and they have lots of feature we don't need.

Since CLI is not for everyone, I made request, minimal http client for your toy projects.

### Download
You can download request from [here](https://github.com/aiocat/request#download)

### Usage
Download the installer from github releases and enjoy! The UI is made childish for everyone to understand.

Python code guidelines for unified, streamlined development
Tags: python, beginners, opensource, tutorial
Published: 2022-04-12 12:26:45

In Python programming, there are many things that developers have to consider and keep in mind when writing code. Those issues and practices differ from company to company and from team to team. At Evrone, we created our own collection of guidelines for Python, in order to build a common denominator for writing code within the company.

Shell command options you didn't know you needed #7
Tags: shell, bash, unix, linux
Published: 2022-04-12 12:26:40

`grep` has lots of options. This one's really a combination of three to do something nifty. 

On the [previous post](https://dev.to/fleetfootmike/shell-command-options-you-didnt-know-you-needed-6-7pn), I was converting a bunch of `iso-8859-1` files to `utf-8`. Setting aside for the moment the fact that I was using `iconv` for this (read the fine man page!), you might perhaps be wondering, how did I know which files I wanted to convert?

First off, this is not magic. It presupposes that you know the files are `iso-8859-1` and that your locale is set to `utf-8`. The latter is easy enough - check your LANG environment variable and set it to something suitable if it doesn't already end in '`.UTF-8`' or '`.utf8`' (detailed discussion of this not for this article).

The former is your problem. I can't really help you with this - data is a bunch of bytes plus an encoding you may or may not know :D So. Assuming you have a reasonable level of certainty these files are encoded to `iso-8859-1`, run this:

`grep -axv '.*' mysuspectfile`

It will return any lines with `iso-8859-1` characters that are not legal `utf-8`, which is to say pretty much anything with its high bit set. 

> Sidebar: Before anyone jumps on me, yes there are obscure combinations of high-bit-set `iso-8859-1` characters that **are** legal `utf-8`, but they are sufficiuently unlikely in any normal text written by people not on weird psychoactive substances for this test to be pretty reliable. Reference [here](https://stackoverflow.com/questions/22868271/how-to-detect-latin1-and-utf-8) for more details.

Why does this work?

- `-a` says 'treat this file as printable text'
- `-v` says 'invert this match'
- `-x` says 'match the whole line against the pattern `.*`'

`.*` (because of `-a` and your locale) means 'any legal `utf-8` character'. The `-x` requires every character in the line to match that pattern, and the `-v` will then spit out lines for which that is not the case.

To generate just a list of offending files from a directory, then, we can use `-r` to recurse down the directory, and `-l` to just report matching filenames.

`grep -r -l -axv '.*' mydirectory`

Bingo. All ready to throw at [`xargs -P`](https://dev.to/fleetfootmike/shell-command-options-you-didnt-know-you-needed-6-7pn) :D
Cross-thread operation not valid fix - C# back ground worker
Tags: backgroundworker, csharp, winform
Published: 2022-04-12 12:10:12

## How to fix 

When you try to access a component in the UI from a Background Worker DoWork event in C#.net, may end up like this.

> System.InvalidOperationException: 'Cross-thread operation not valid: Control 'listView1' accessed from a thread other than the thread it was created on...

## Solution
 
 To bypass this error C#.Net  provides **invoke  ** method which execute the **delegate **specified. 

Invoke let us directly interact from other threads. 

To add items to a listview from a  background  worker I used the following code snippet which uses a  **MethodInvoker  **and a  **delegate **

`listView1.Invoke(new MethodInvoker(delegate
                                 {
                                     item = new ListViewItem("");
                                     item.SubItems.Add(new ListViewItem.ListViewSubItem(item, "Some Column Value Here"));                                       
                                     listView1.Items.Add(item);
                                 }
                                 ));  `

Why Choose React Framework For Front End Development
Tags: webdev, react, frontend, development
Published: 2022-04-12 12:02:30

There are a variety of [front-end development frameworks available](https://www.flippingheck.com/why-choose-react-frameworks-for-front-end-development/), with React being one of the most popular and frequently utilized. React is an open-source JavaScript UI framework for building scalable, quick, and easy-to-maintain frontends for online applications. 

Although some developers like to refer to React.js as a web development framework, it is officially a library because it only interacts with user interfaces and other front-end elements. React is a declarative coding language that excels in flexibility, usability, and, of course, rendering user interfaces.

React was the first web development framework to achieve domain balance, and it is now the most widely used web development library among web developers.

Reverse String Without Changing Place of Special Characters
Tags: programming, python, coding, competitiveprogramming
Published: 2022-04-12 11:44:59

Hi Programmer,

Today we are going to solve a string problem in python. Here you will get a string containing numbers and some special characters. We have to reverse this string without changing the place of the special characters.

**Input: ** "123$456%789*0^"

**Output: ** "098$765%432*1^"

So let's start our coding

**Solution: 1**

```
seq = "123$456%789*0^"
output = "098$765%432*1^"

chars = ['$', '%', '*', '#', '^']
nums = []

for i in range(len(seq)):
    if seq[i] not in chars:
        nums.append(seq[i])

nums.reverse()

for j in seq:
    if j in chars:
        idx = seq.index(j)
        nums.insert(idx, j)

reverse = "".join(nums)

print(reverse)

```

**Solution: 2**

```
ip_str = "123$456%789*0^"

rev_str = reversed(ip_str)
op_str  = ""
for value in ip_str:
  if value.isdigit():
    for rev_val in rev_str:
      if rev_val.isdigit():
        op_str += rev_val
        break
  else:
    op_str += value
print(op_str)
```


Here there were two types we can solve this problem. There can be more type also if you find anything, let's discuss in the room.

What is an application programming interface (API)?
Tags: webdev, programming
Published: 2022-04-12 11:39:36

Application Programming Interface is the abbreviation for API.

An API is a set of programming instructions that allows data to be exchanged between two software applications.

APIs allow a programmer to write code to one piece of software that can then perform specific tasks without the programmer having to start from zero.

APIs allow a program to access software (or web-based data) in a regulated and secure manner.

The code that sends requests to the receiving program and returns data can then be created.

Underrated Tips for Junior Position
Tags: discuss, career
Published: 2022-04-12 11:23:45

Even though I am still waiting for my second Interview result for Junior PHP Developer position, I've found a pretty overlooked advice for Junior Developer positions on YouTube comment section, which is to learn how to read other people's code especially if you're working on team. Spend your time on making sense of your colleague/ex-colleague's codes. Getting up and running with the new code base is an absolute must.

This is why I always check other people's code on their Github with the benefits to make my coding view more broad and flexible.
Types of Computer Softwares
Tags: architecture, ios, software, computerscience
Published: 2022-04-12 11:15:31

> Software comprises the entire set of programs, procedures, and routines associated with the operation of a computer system.

There are three different types of software that can run on a computer,
They are

1. System Software
2. Utility Software
3. Application Software

Let's take a closer look at them.

**1. System Software**

If you think of software as being in layers, the system software is the bottom layer. It works as a medium in between the hardware and the application software.

Operating systems like windows, macOS, Android and iOS are examples of system software. Operating systems are loaded into RAM when the device starts up, and have access to the hard drive.



**2. Utility Software**

It is part of the system software and performs specific task to keep the computer running. Utility software is always running in the background. Security and optimisation programs are the best examples for the utility software.

Security programs include anti-virus software that scans and removes viruses from the system. Most computers will include some sort of anti-virus software, but you can add your own.


**3. Application Software**

This is everything else! Anything that is not an operating system or  utility is an application or app, So a word processor spreadsheet, web  browser, and graphics softwares are all examples of application software, and they can do specific tasks.

You can remove and add application on your computer using the operating system.
Reusable SQL templates: learn about SQL Macros🤯

![SQL Table Macro](https://dev-to-uploads.s3.amazonaws.com/uploads/articles/xhrqcvwldz0f0gymsmyn.gif)

👉SQL Table Macro: create reusable SQL templates (FROM clause) you can pass tables, and other parameters to at runtime.


Documentation: https://docs.oracle.com/en/database/oracle/oracle-database/19/newft/sql-macros-sqm.html

SQL Table Macro is a 21c feature backported to the 19.7 release update.

```
CREATE TABLE planets (
    json_document BLOB,
    CONSTRAINT json_document_is_json CHECK (json_document IS JSON)
);

INSERT INTO planets (json_document) 
VALUES ( '[ {"name":"Mercury"}, {"name":"Venus"}, {"name":"Earth"}, 
            {"name":"Mars"}, {"name":"Jupiter"}, {"name":"Saturn"}, 
            {"name":"Uranus"}, {"name":"Neptune"} ]' );
COMMIT;

-- One row retrieved containing a JSON array
SELECT JSON_SERIALIZE(json_document) AS array FROM planets;

                                                       ARRAY
-------------------------------------------------------------
[ {"name":"Mercury"}, {"name":"Venus"}, {"name":"Earth"}, … ]


-- Second version where the column table is also a parameter
CREATE OR REPLACE FUNCTION unwind(t DBMS_TF.TABLE_T, c DBMS_TF.COLUMNS_T) 
       RETURN VARCHAR2 SQL_MACRO IS
BEGIN
  RETURN := q'{
      SELECT d.array_item AS JSON_DOCUMENT, d.order_id
        FROM unwind.t nested }'|| unwind.c(1) ||q'{ COLUMNS (
                 NESTED PATH '$[*]' COLUMNS (
                     array_item CLOB FORMAT JSON PATH '$',
                     order_id FOR ORDINALITY
                 )
             ) d}';
END;
/
-- Using a table and one of its columns as parameters of SQL Macro
SELECT * FROM unwind( planets, COLUMNS( json_document ) );         

     JSON_DOCUMENT   ORDER_ID
------------------ ----------
{"name":"Mercury"}          1
  {"name":"Venus"}          2
  {"name":"Earth"}          3
   {"name":"Mars"}          4
{"name":"Jupiter"}          5
 {"name":"Saturn"}          6
 {"name":"Uranus"}          7
{"name":"Neptune"}          8
```

The example above uses the second version of my SQL Macro (compared to the animated GIF above) where I can also pass a column as a parameter!
