Introduction to Multithreading
Published: 2024-01-09 07:26:51

C# Introduction to Multithreading

Multithreading is a powerful concept in computer programming that allows multiple tasks or processes to run concurrently. It plays a significant role in optimizing system performance and responsiveness. In C#, multithreading is made easy with the help of the Task Parallel Library (TPL) and the Thread class.

The TPL provides high-level abstractions for working with concurrency, making it simpler for developers to harness the benefits of multithreading. By making use of the TPL, you can easily execute tasks asynchronously, regardless of whether they are CPU-bound or I/O-bound.

The Thread class, on the other hand, provides a lower-level approach to multithreading in C#. It allows you to create and manage threads directly, giving you more control over their execution and synchronization.

To start with multithreading in C#, you need to understand the concept of threads. A thread is an independent path of execution within a program. By default, all C# programs have a main thread, representing the entry point of the program. However, you can create additional threads to perform tasks concurrently with the main thread.

Using the TPL, you can create tasks that run in parallel, taking advantage of multiple CPU cores. This enables you to speed up the execution of computationally intensive operations. The TPL also offers various high-level constructs, such as parallel loops and parallel LINQ, to simplify parallel programming.

On the other hand, the Thread class allows you to explicitly create and manage threads. You can create a new thread by instantiating the Thread class and passing a delegate method that the thread will execute. Additionally, you can control the thread's behavior using methods like Start(), Sleep(), Join(), and Abort().

However, multithreading introduces new challenges like synchronization and coordination between threads. These challenges arise when multiple threads access shared resources simultaneously, leading to data corruption or unexpected program behavior. To address this, C# provides various synchronization primitives, such as locks, semaphores, and mutexes, to ensure thread safety.

In conclusion, multithreading in C# is a powerful technique for improving the performance and responsiveness of your programs. Whether you choose to use the TPL or the Thread class, understanding the basics of multithreading will open up new possibilities for parallel programming and efficient resource utilization.
Menggunakan Library Datatable di Bootstrap 5
Tags: datatable, bootstrap
Published: 2024-01-09 07:34:59

Include CSS nya di header

```html
<link rel="stylesheet" href="//cdn.datatables.net/1.13.7/css/dataTables.bootstrap5.min.css" />
```

Include JS nya sebelum tag `</body>`

> Datatable membutuhkan jQuery, jika sudah di include bisa di skip

```html
<script src="//code.jquery.com/jquery-3.7.0.js"></script>
<script src="//cdn.datatables.net/1.13.7/js/jquery.dataTables.min.js"></script>
<script src="//cdn.datatables.net/1.13.7/js/dataTables.bootstrap5.min.js"></script>
```

Deklarasi datatable untuk table dengan id `datatable`

```html
<script>
$(document).ready(function () {
    $("#datatable").DataTable({
        searching: true,
        search: {
            smart: false,
        },
        paging: true,
        lengthChange: true,
        ordering: true,
        info: true,
        language: {
            // menggunakan bahasa Indonesia
            url: "//cdn.datatables.net/plug-ins/1.13.7/i18n/id.json",
        },
    });
});
</script>
```

`searching`, `paging`, `lengthChange`, `ordering` dan `info` semua nilai default nya adalah `true`, jadi config tersebut bisa dihilangkan, kecuali mau diubah nilai nya ke `false`

```html
<script>
$(document).ready(function () {
    $("#datatable").DataTable({
        search: {
            smart: false,
        },
        language: {
            // menggunakan bahasa Indonesia
            url: "//cdn.datatables.net/plug-ins/1.13.7/i18n/id.json",
        },
    });
});
</script>
```

Opsi `smart` di set `false` karena secara default, Datatable menerapkan smart filtering

Jadi jika keyword pencarian dua kata atau lebih, dia akan split kata-kata tersebut menjadi masing-masing dan melakukan pencarian dari dua kata tersebut

Contoh table

```html
<table class="table" id="datatable">
    <thead>
        <tr>
            <th>No</th>
            <th>Nama</th>
            <th>Username</th>
            <th>Role</th>
            <th>Aksi</th>
        </tr>
    </thead>
    <tbody>
        <!-- looping data -->
    </tbody>
</table>
```

Confirmed reserves on the Binance exchange exceed a ratio of 100%
Tags: news, blockchain, cryptocurrency
Published: 2024-01-09 11:43:10


The latest Proof of Reserves (PoR) report from Binance shows that the net balances of XRP clients amount to over 2.7 billion tokens (over $1.5 billion at current rates). The net balances of the exchange, in turn, amount to over 2.8 billion in assets, corresponding to a ratio of 104.26%.

The Proof of Reserves system is designed to ensure transparency and build trust among Binance users by demonstrating that the company is capable of covering the balances of all clients on a 1:1 basis.

In other words, this guarantees that client funds are fully backed, which is particularly important given the bankruptcy of some major cryptocurrency exchanges, including FTX, which commingled client assets with its own.

The net balances of the trading platform in Bitcoin and Ethereum also have positive ratios, amounting to 103.79% and 106.56%, respectively.
Among other cryptocurrency exchanges that have published similar reports in recent months are Crypto.com, Kraken, OKX, and others.

Help with Font Sizes
Published: 2024-01-09 16:44:44

Hello, first post here. 

I was wondering how everyone chooses their font sizes on their portfolios. Is there some sort of industry standard that you like to use where for example the sub header is 1.6x the size of the text beneath? Also how to you like to change the font in regards to a small, medium and large screen such as phone, ipad, desktop monitor?

Thank you in advance.

1886 hours to break dev
Tags: webdev, testing, experience, discuss
Published: 2020-07-02 19:49:57

##Today I broke the dev testing environment.
I'm not bothered by it. And you shouldn't be either. 
___


I don't feel any shame in breaking the env, and I apologised to my colleagues for the inconvenience. Fixing simply involved restoring last nights database backup.

Breaking it was my mistake, I uploaded the wrong file to the testing environment and imported various things that were incompatible with it. 

___
It happens to all of us sometimes and we shouldn't be scared of breaking testing environments. They should be easy to revert. I used to be scared of breaking things and it can cause massive problems for other devs. 

If the env is full of test data, either back up the database or have some scripts to flood your api and fill it back up (bonus as you get to test the api works at the same time).
___
I've previously completely destroyed test environments for several teams at once, letting most of the team have a reason to go for an early lunch. It happens, and in some cases was expected to happen due to the nature of changes (deployment flow, significant api changes etc). 

It's also *really* useful to break the dev environment, you learn quickly how to fix it and hopefully how to avoid making the same error in future or at least minimise the impact of the upcoming changes when it's time to release the changes to the client/public.

There is a lot of confidence that can be gained in breaking an environment, production or testing. Hunting for issues in code can really help you learn a codebase quickly, so don't instantly be put off if you start a new job and the code looks huge or you end up fixing bugs. As you fix the bugs and learn the codebase you gain confidence with it. With that you can then make changes and most importantly, *you know where to look to fix new bugs*.

___

###So why the 1886? Why hours?
It's been a while since I broke an environment, especially where it affected other developers. I managed probably 1886 hours since I last broke a dev environment. It sounds exact but at my previous job I broke something almost daily and a lot of the time no-one even noticed. The issue was fixed before anyone else found it or before it rolled out to thier environment. 

Sometimes I've redeployed infrastructure and broken dev environments _several times_ in one day. I could tell when it broke as people would start appearing at my desk waiting patiently for me to finish what I was doing, and the slack notifications would build up.

Don't cave to the pressure (even if typing with people behind you makes you screw up), you can probably can fix it, and if you can't, you can learn a hell of a lot working with someone who can fix it.

Have you broken an environment? Did it affect lots of people? Did you manage to fix it?

WHAT IS A PACKAGE MANAGER?
Published: 2024-01-10 09:32:49

WHAT IS A PACKAGE MANAGER?

A package manager is a software tool designed to simplify the process of installing, updating, configuring, and removing software packages on a computer's operating system. 

It is a crucial component of many modern software ecosystems and is particularly prevalent in Unix-like systems (such as Linux) and some other operating systems.

Here are key functions performed by a package manager:

Package Installation: Package managers automate the process of downloading, installing, and configuring software packages. Users can specify which packages they want, and the package manager handles the dependencies, ensuring that all required components are installed.

Dependency Management: Software often relies on other software components or libraries to function properly. A package manager resolves and installs these dependencies automatically, saving users from the manual effort of tracking and managing dependencies.

Version Control: Package managers keep track of software versions and can upgrade or downgrade packages as needed. This helps maintain a consistent and compatible software environment.

Configuration Management: Some package managers allow users to configure the installed software. Configuration files can be managed, and updates to packages can be applied while preserving custom configurations.

Uninstallation: Package managers facilitate the removal of installed software and associated files. This helps in cleaning up the system and avoiding conflicts between different versions of the same software.

Security Updates: Package managers often include mechanisms for updating software packages to patch security vulnerabilities. Regularly updating packages through the package manager is a good security practice.

Examples of popular package managers include:

APT (Advanced Package Tool): Used by Debian-based systems like Ubuntu.
YUM/DNF: Commonly used on Red Hat-based systems like Fedora and CentOS.
Homebrew: Popular on macOS for managing software packages.
npm (Node Package Manager): Used for managing Node.js packages.
pip: Python's package installer.
Different operating systems and programming languages may have their own package management systems, each tailored to the specific needs and conventions of their respective ecosystems.

How to handle complex json schema
Tags: databricks, json, schema, dataframe
Published: 2024-01-18 02:08:18

I am working in databricks.  I have a mounted external directory that is an s3 bucket with multiple subdirectories containing call log files in json format.  The files are irregular and complex, when i try to use spark.read.json or spark.sql (SELECT *) i get the UNABLE_TO_INFER_SCHEMA error.  the files are too complex to try and build a schema manually, plus there are thousands of files.  what is the best approach for creating a dataframe with this data?
