How to connect to MySQL remotely with SSH PuTTY Tunnels: A step-by-step guide

Categories

Tags infosec cloud devops database servers

MySQL is a popular relational database management system to organize and store data. Depending on your specific use cases and preferences, you can connect to a MySQL Server through a command-line interface, using GUI tools,such as dbForge Studio for MySQL, programming languages or via web-based interfaces such as phpMyAdmin. By Julia Evans.

In this article, we’ll give a brief overview of SSH protocol and tunnel, as well as explore how to connect to a MySQL server remotely using the SSH tunnel created with the help of PuTTY, a popular Windows SSH client. Further in the article:

  • Introduction to SSH tunnel
  • What is PuTTY?
  • PuTTY: Pros and Cons
  • Advantages of MySQL secure connection
  • How to access a MySQL server remotely by creating an SSH tunnel with PuTTY
  • How to connect to the MySQL server through PuTTY using dbForge Studio for MySQL
  • Method 1: Connect to the MySQL server through the password authentication
  • Method 2: Connect to the MySQL server using the Plink command-line interface
  • Benefits of using a GUI tool to connect to MySQL

The SSH protocol operates on the client-server model, which means that the connection to the SSH server is created by the SSH client directly without being intercepted by third parties. The protocol uses authentication to enable communication between two remote systems – host and client – through a secure encrypted channel. The host is the remote server to access, while the client is the computer to be used to access the host.

To sum it up, connecting to a remote MySQL server through an SSH tunnel is a secure and reliable way to access your database and ensure the safety of your data to transmit. Good read!

Increase availability & container images caching thanks to kube-image-keeper

Categories

Tags docker devops containers distributed apis

At Enix, we manage hundreds of Kubernetes clusters for our customers and our own internal use. On cloud, on premises, big and small, from development to production… And there is one particular issue that hits all these clusters at one point or another: the image retrieval process. By Nicolas Gouze.

Every Kubernetes administrator has faced, or will face, this issue sooner or later: you roll out an update to patch a security issue, fix a bug or rollback to a stable release after a faulty update. And then, surprise: on a few nodes of the cluster, some containers won’t start because the image can’t be pulled. The registry might be down, or having a bad day, or the image might have been removed, or you might be hitting your Docker Hub pull quota. Either way: you’re SOL (sadly out of luck).

Author walk you through describing the options that they considered before writing their own container image caching solution, then he’ll describe the architecture of their solution, and he’ll tell you how to get started with it:

  • Adventures, twists & turns before finding our target architecture!
  • kubernetes-image-puller: interesting idea, but not for us
  • An “out of the box” solution with kube-fledged?
  • Tugger in harmony with Harbor?
  • kuik, our image caching solution: Docker registry + dev!

A container image caching solution to ensure that any image, pulled at least once into our kubernetes cluster, gets saved to a reliable, trusted cache. Nice one!

Technical differences between WEB 2 and WEB 3: A developer's perspective

Categories

Tags crypto blockchain fintech learning how-to

Web2 refers to the internet’s second generation, in which websites and web applications are centralized. For many years, Web2 has been the standard, with a client-server architecture and data stored on central servers controlled by a few large corporations. By Nxtgen Virtue.

This centralized approach has drawbacks in terms of privacy, security, and data control. Web3, on the other hand, is a decentralized version of the internet in which users distribute and control data using blockchain technology. This improves transparency, security, and control over personal data.

In this article you will find information on differences in:

  • Protocols
  • Architecture
  • Data sharing
  • Data storage
  • Network
  • Security
  • Web applications

Web2 and Web3 differ significantly in terms of technical architecture, protocols, data sharing, storage, network structure, security, and application development, with Web3 representing a paradigm shift in terms of its technical architecture, protocols, data sharing, storage, network structure, security, and application development.

Tags big-data data-science machine-learning app-development learning

Predicting temperature trends with advanced deep learning techniques using LSTM. Weather forecasting is one of the most important tools in the modern world and developing a good temperature prediction model can be a huge competitive advantage for many businesses. Ambient temperature measurement is directly linked to several business areas such as agriculture, energy sector, trading, aviation, and many other sectors. By Octavio Santiago.

In this article, we will learn how to build LSTM Deep Learning models to forecast temperature precisely:

  • The dataset used for training was taken from the INMET
  • LSTM (Long Short-Term Memory) is a type of recurrent neural network (RNN) architecture
  • Train and benchmarks
  • LSTM Vanilla
  • LSTM Stacked

The main outcome in training a Time Series model is how to split the dataset correctly into train and test datasets. Since the sequence is important we cannot split the dataset randomly, to split the dataset right, the sklearn function “TimeSeriesSplit” is being used. In the 48-hour prediction Stacked LSTM model showed a lower Average absolute error and a lower maximum temperature error as well, showing that adding complexity to the model was beneficial for these LSTM models and fitting data.

A controversial feature is coming to Microsoft’s browser just as the crypto markets are suffering. By Tom Warren.

Microsoft is building a cryptocurrency wallet for its Edge browser even as the crypto markets struggle. Sources familiar with Microsoft’s plans tell The Verge that the software giant has been testing the Microsoft Edge built-in crypto wallet internally in recent months, with plans to eventually ship it to consumers. It’s just the latest feature coming to Microsoft’s increasingly bloated Edge browser.

Screenshots of the crypto wallet leaked online last week thanks to Twitter user Albacore, who regularly documents unreleased features in Windows. Microsoft’s description of the crypto wallet says it has “simplified experiences that make Web3 easier to interact with” and that it has “integrated security features to protect you from unsecure addresses or apps.”

Microsoft Edge will advertise the ability to purchase cryptocurrency from Coinbase and MoonPay through the built-in crypto wallet. It will also include the ability to connect decentralized apps to the wallet feature and support collecting and storing non-fungible tokens (NFTs).

The appearance of this Edge crypto wallet comes just days after Microsoft added a giant Bing button to its Edge browser in an effort to push people toward its search engine. Good read!

In this article, we are going to learn how to design Jira Board like UI using React with Tailwind CSS and how to manage its state using Context API. Also we are going to implement our own custom Drag and Drop feature by implementing reusable custom hooks. By Altamash Ali.

Deciding on component hierarchy

Source: https://www.altamashali.net/blog/design-and-implement-jira-board-with-drag-and-drop-using-react-and-tailwind-css

We are going to implement the whole feature in this post, so it is better to plan step by step how we can approach the problem. I am going to divide the whole problem into three steps:

  • Designing and implementing the UI
    • What should be optimal component hierarchy for this UI
    • How does the data flow work with the proposed component design considering performance scenarios like minimizing extra re-renders
  • Managing the state of the component hierarchy
    • What should be the interface of the state for the UI
    • How can we optimize state design
  • Implementing Drag and Drop feature
    • Implementing custom hooks for the Drag and Drop
    • Using custom hooks in our UI

We liked how author though about deciding on component hierarchy, data structure and data flow through component hierarchy. Very interesting!
