  • Pinebook Pro, First Impressions

    After seeing it in action at FOSDEM (from afar, as the crowd was too large), I decided to buy a Pinebook Pro for personal use. From the beginning, the intention was to use it for pkgsrc development, with NetBSD as the main OS. It was finally delivered on Thursday, one day earlier than promised, so I thought I would write down my first impressions.

    If you have never heard of the Pinebook Pro: It is a cheap, open, hackable laptop with an ARM processor, the successor of the original Pinebook (which I thought was too low-end to be a useful daily driver) with generally more premium components.

  • What’s the deal with edge computing?

    With over 41 billion IoT devices expected to be active by 2027 — that’s at least 5 devices for every person on the planet — edge computing has emerged as a tenable solution to prevent the impending snowballing of network traffic.

    Allow me to lift the veil on this buzzword and explain why it’s been gaining attention in tech circles lately.

    The concept

    IoT devices generate a lot of data. Smart home hubs constantly accrue information on voice commands, ambient noise, and auxiliary device output. Connected security cameras transfer several gigabytes of image data each day. And self-driving cars will, in all likelihood, be gathering hundreds of terabytes of data each year.

    The idea of edge computing is to process all this data at the location it is collected. Data that is only of ephemeral importance can (and should) be crunched on the device itself. This is in contrast to cloud computing, where data is sent to massive, far-away compute warehouses for processing.

  • 10th Gen Comet Lake computer has GTX GPU and 10 GbE ports

    Sintrones’ fanless, Linux-ready “ABOX-5210G” transport PC features an up to 10-core Comet Lake-S CPU, Nvidia graphics, 3x M.2, 2x mini-PCIe, 3x DP, 2x HDMI, 2x SATA, and 10x GbE ports with optional PoE.

    Sintrones has announced the second embedded PC we’ve seen with an Intel 10th Gen Comet Lake-S processor after Vecow’s recent ECX-2000 Series. The fanless ABOX-5210G uses slightly lower powered, but more power-efficient Core TE Comet Lake-S models than the Vecow system, including a 2.0GHz/4.5GHz Core i9-10900TE. There is also a 2GHz/4.6GHz Xeon W-1290TE, which similarly offers 10x dual-threaded cores, 20MB Intel Smart Cache, and a 35W TDP.

  • Find the coefficients of the Quadratic Equation of the given two roots with Python

    In this example, you are expected to find the coefficients of the quadratic equation of the given two roots (x1 and x2) with a python function. The Quadratic Equation looks like this ax^2 + bx + c = 0. Our mission is to find the coefficients of the equations which is a, b, and c. The return type from the function is a Vector containing coefficients of the equations in the order (a, b, c). Since there are infinitely many solutions to this problem, we fix a = 1. Below is the method to find the return Vector.

  • Python 3.9.0b4

    Python 3.9 is still in development. This release, 3.9.0b4, is the fourth of five planned beta release previews. Beta release previews are intended to give the wider community the opportunity to test new features and bug fixes and to prepare their projects to support the new feature release.

  • Python 3.9.0b4 is now ready for testing

    On behalf of the entire Python development community, and the currently serving Python release team in particular, I’m pleased to announce the release of Python 3.9.0b4.

  • 10 most useful Python Dictionary Methods

    Dictionary is used in python to store multiple data with key-value pairs. It works like an associative array of other programming languages. The curly ({}) brackets are used to define a dictionary and the key-value is defined by the colon(:). The content of the key and value can be numeric or string. Python has many built-in methods to do different types of tasks on the dictionary data such as add, update, delete, search, count, etc. 10 most useful dictionary methods of python are explained in this article.

  • 10 most useful Python String Methods

    The string data is the characters of an array that contains one or more characters as value for any programming language. All printable characters such as alphabets, numbers, special characters, etc. are commonly used in the string data. ASCII code and Unicode are mainly used for converting any character to a number that the computer can understand. Python uses Unicode characters for string data. We need to perform different types of tasks based on the programming purpose on the string data such as searching the particular character or characters, capitalizing the first character, making all characters uppercase, etc. Python has many built-in string methods to do these types of tasks very easily. The 10 most useful python string methods are explained in this article.
