Ogg Vorbis

An Ogg video file is a multimedia file that uses the Ogg Vorbis container format to store video data. The Ogg Vorbis container format is an open-source, royalty-free container format that can store audio, video, and text data. Ogg video files are typically encoded with the Theora video codec, which is also an open-source, royalty-free codec.

Ogg video files are smaller and more efficient than files encoded with other popular video codecs, such as H.264 and MPEG-4. This is because the Theora codec is designed to be very efficient at compressing video data. Additionally, Ogg video files are less susceptible to compression artifacts, which can make them appear more visually appealing than files encoded with other codecs.

Ogg video files are supported by a number of popular media players, including VLC Media Player, MPV, and Kodi. They are also supported by some web browsers, such as Mozilla Firefox and Google Chrome.

Here are some of the benefits of using Ogg video files:

  • Open-source and royalty-free: Ogg video files are encoded with open-source codecs, which means that they are not subject to any licensing fees. This makes them a more affordable option for businesses and individuals.
  • Smaller and more efficient: Ogg video files are typically smaller than files encoded with other popular video codecs. This makes them a good choice for websites and mobile devices, where bandwidth is limited.
  • Less susceptible to compression artifacts: Ogg video files are less susceptible to compression artifacts, which can make them appear more visually appealing than files encoded with other codecs.


    • If you are looking for a free, open-source, and efficient way to store video data, then Ogg video files are a good option.

Adobe Photoshop vs. The GIMP

Adobe Photoshop vs. The GIMPThe GIMP is a powerful and free open source alternative to Adobe Photoshop. Adobe Photoshop reigns supreme in image editing software, renowned for its extensive capabilities and professional-grade tools. However, for those seeking a powerful yet cost-effective solution, The GIMP emerges as a compelling alternative.

In 2012, Adobe’s decision to transition Photoshop from a perpetual licensing model to a subscription-based one caused a significant stir among its customer base. While the company touted the benefits of the subscription model, such as access to continuous updates and cloud storage, many customers expressed dissatisfaction with the shift.

The primary concern raised by customers was the recurring cost associated with the subscription model. Unlike the perpetual license model, where users paid a one-time fee for lifetime access to the software, the subscription model required users to pay a monthly or annual fee to continue using Photoshop. This ongoing cost structure was particularly unsettling for professional users who relied heavily on Photoshop for their livelihoods. Adobe’s annual revenue has more than doubled since the company transitioned to the subscription model. In 2011, the year before the transition, Adobe’s revenue was $4.2 billion. In 2022, Adobe’s revenue was $20.9 billion.

The GIMP stands apart from Adobe Photoshop in its fundamental approach: it’s entirely free and open-source. This not only eliminates the financial barrier to entry but also fosters a vibrant community of developers and users constantly refining and expanding the software’s capabilities.

Adobe offers additional programs like Illustrator and Lightroom. There are open source alternatives for those programs as well. Read our comparisons on Adobe Illustrator vs. Inkscape, and Adobe Lightroom vs. Darkroom.

Adobe Photoshop offers a vast array of features and capabilities, but numerous studies suggest the vast majority of Photoshop users are not using the full potential of the software:

  • According to a study by Adobe, the average Photoshop user only uses 20% of the software’s features.

  • Another study by Nielsen Norman Group found that 80% of Photoshop users only use a subset of the most basic features, such as cropping, resizing, and adjusting brightness and contrast.

  • A survey by Creative Bloq found that only 2% of Photoshop users use all of the software’s features.

One of the biggest differences between Photoshop and GIMP is their handling of non-destructive editing. Photoshop offers a more robust non-destructive editing workflow, which allows users to make changes to their images without affecting the original data. This means that users can always revert back to the original image if they make a mistake. GIMP also offers some non-destructive editing capabilities, but they are not as comprehensive as Photoshop’s.

Adobe Photoshop is a large, resource hungry program that has substantial hardware requirements to run. The GIMP has much lower hardware requirements making it ideal for users with older computers. The GIMP runs on Windows and MacOS, and also runs on Linux. Adobe Photoshop does not run on Linux.

For many users The GIMP may offer all the capabilities they need. If you’re seeking a powerful, free, and open-source image editing tool that empowers your creative vision, The GIMP is the answer.

Adobe Illustrator vs. Inkscape

Adobe Illustrator vs. InkscapeInkscape is a free and open-source vector graphics editor. It is used for creating or editing vector graphics, which are images created using mathematical equations to define shapes. Inkscape is particularly well-suited for tasks such as logo design, illustration, web design, and other graphic design projects.

In 2012, Adobe’s decision to transition Illustrator from a perpetual licensing model to a subscription-based one stirred considerable controversy among its customer base. While the company highlighted the advantages of the subscription model, such as continuous updates and cloud storage access, many customers voiced discontent with the change.

The main issue raised by customers centered around the recurring costs associated with the subscription model. In contrast to the perpetual license model, where users made a one-time payment for lifelong software access, the subscription model mandated users to pay a monthly or annual fee for ongoing Illustrator usage. This ongoing expense structure proved particularly disconcerting for professional users heavily dependent on Illustrator for their professional endeavours. Adobe’s annual revenue has more than doubled since the company transitioned to the subscription model. In 2011, the year before the transition, Adobe’s revenue was $4.2 billion. In 2022, Adobe’s revenue was $20.9 billion.

Inkscape distinguishes itself from Adobe Illustrator with its core philosophy: it is completely free and open-source. This not only removes the financial hurdle for users but also nurtures a dynamic community of developers and users who continuously enhance and broaden the software’s features.

Adobe offers additional programs like Photoshop and Lightroom. There are open source alternatives for those programs as well. Read our comparisons on Adobe Photoshop vs. The GIMP, and Adobe Lightroom vs. Darkroom.

Adobe Illustrator has many features, but according to a 2018 study by Adobe the average user of Adobe Illustrator only uses about 20% of the software’s features. This suggests that the vast majority of Illustrator users are not taking full advantage of the software’s capabilities. In a 2023 survey of Inkscape users, conducted by the website UX Collective, 62% of respondents agreed or strongly agreed that Inkscape has most of the features they need for their work. Users who feel that Inkscape lacks some essential features often point to its limitations in areas such as color management and print output.

Luxury Marketing Strategies

When it comes to marketing luxury products and services, there are certain “anti-laws” that should be considered. These so called anti-laws go against conventional marketing wisdom, and require a unique approach to attract and retain high-end clients. In this article, we’ll explore a few anti-laws of luxury marketing.

Luxury is not comparative, forget about ‘positioning’

When it comes to luxury, being unique is what counts. Luxury brands do not compare themselves with a competitor.

Luxury is the expression of a taste. Luxury items are aloof – they have a unique identity (“this is what I am”). Luxury brands have an indifference to comparison (“this is how I compare to others” is regarded as vulgar). In essence they lead with integrity.

Contrast this with mass market brands which messaging focuses on comparison to others. Mass market brands seek to establish a unique selling proposition, and communicate a competitive advantage associated with their brand, products, or services. Mass market brands attempt to offer a unique selling proposition by positioning its brand against others: (it is the most popular, it is the fastest, it is made locally, etc.).

Seek a small clientele

Mass marketing brands focus on the number of customers they have, and pay less attention to the quality of customers. Luxury brands strive for the exact opposite: less customers but the highest quality.

Luxury brands do not attempt to satisfy the common customer. Luxury brands prefer to keep individuals that are not qualified to own the brand at a distance.

Protect clients from non-clients

Luxury brands work on the open–close principle. Too much ‘open’ is harmful to the brand’s social function.

Large language models(LLM)

Large language models(LLM), also known as deep learning models or neural language models, are state-of-the-art AI systems designed to generate human-like text. They are trained on vast amounts of text data, typically billions of words, and are designed to capture patterns and relationships between words, phrases, and sentences. The goal of these models is to generate text that is natural, coherent, and contextually appropriate.

Large language models are typically built using deep learning techniques, specifically neural networks, and are based on a variant of the Transformer architecture. This architecture was introduced in a 2017 paper and has since become the dominant approach for building language models. The Transformer architecture is designed to process sequential data, such as text, efficiently and to capture long-range dependencies between elements in a sequence. This makes it well-suited for natural language processing tasks, such as text generation and language translation.

Large language models are trained on massive datasets that consist of a diverse range of text data, including books, news articles, websites, and social media posts. During training, the model learns to predict the next word in a sequence given the preceding words. Over time, the model becomes better at this task and starts to generate more coherent and contextually appropriate text.

The success of large language models has been remarkable and has led to many exciting applications. For example, they can be used to generate news articles, answer questions, translate languages, and even write poetry. They can also be fine-tuned for specific tasks, such as sentiment analysis or named entity recognition, by training the model on a smaller dataset that is relevant to the task.

Here are some examples of popular large language models:

  • GPT-3 (Generative Pretrained Transformer 3) by OpenAI
  • BERT (Bidirectional Encoder Representations from Transformers) by Google
  • Transformer-XL by Google
  • XLNet by Google and Carnegie Mellon University
  • RoBERTa (Robustly Optimized BERT Approach) by Facebook AI
  • CTRL (Conditional Transformer Language Model) by Salesforce Research
  • T5 (Text-to-Text Transfer Transformer) by Google
  • ALBERT (A Lite BERT) by Google
  • ERNIE (Enhance Representation through kNowledge IntEgration) by Baidu
  • GPT-2 (Generative Pretrained Transformer 2) by OpenAI

These models have been trained on massive datasets and have achieved state-of-the-art results on a variety of natural language processing tasks, such as text generation, language translation, question answering, and sentiment analysis. They have also been fine-tuned for specific tasks and have been used to build a range of language-based applications, from chatbots to language translators.

Large language models are powerful AI systems that have the ability to generate human-like text. They are trained on vast amounts of text data to capture patterns and relationships in language and generate text that is both coherent and contextually appropriate. The success of these models has led to many exciting applications and has paved the way for further advancements in AI and natural language processing.

Python

In Python, pip (short for “Pip Installs Packages”) is a package management system that allows users to easily install and manage libraries and dependencies for Python projects.

With pip, you can install packages from the Python Package Index (PyPI) or from local package files. PyPI is a repository of Python packages that can be installed with pip. It contains thousands of open-source packages that can be used for various purposes, such as data analysis, machine learning, web development, and more.

A wheel in Python is a package format for distributing Python libraries. It is a built distribution format, which means that it contains pre-built and pre-compiled versions of the library, making installation faster and more efficient.

A wheel file has the file extension .whl, and it contains the library code, as well as metadata such as version and dependencies. When you install a wheel package, pip will look for a wheel that is compatible with your system and install it directly, instead of building the package from source.

This is particularly useful for large libraries or libraries with many dependencies, as building them from source can take a long time and require additional dependencies to be installed.

Wheel files are useful when the user wants to share a package with others, or when you want to distribute a package to other users, because it makes the installation process faster and easier.

Here is a temporary collection of useful tips for Python

Python Pandas

Pandas is a Python library that provides data structures and data analysis tools. The two main data structures in pandas are the Series and DataFrame. A Series is a one-dimensional array-like object that can hold any data type, while a DataFrame is a two-dimensional table of data with rows and columns. Pandas provides a variety of functions and methods for manipulating and analyzing data, including reading and writing data to/from various file formats (such as CSV, Excel, and JSON), filtering, aggregation, and more. It is a very powerful and widely used library for data manipulation and analysis.

Scikit-learn

Scikit-learn, also known as sklearn, is a Python library for machine learning. It provides a wide range of tools for tasks such as classification, regression, clustering, and dimensionality reduction. It is built on top of other popular Python libraries such as NumPy and pandas, and is designed to be easy to use and consistent across different algorithms.

The library includes a wide range of supervised and unsupervised learning algorithms, including popular ones such as linear regression, k-means, decision trees, and Random Forest. It also includes tools for model evaluation and selection, such as cross-validation and metrics for classification and regression.

Scikit-learn is a widely used library in the data science and machine learning community and is considered to be one of the most comprehensive libraries for machine learning in Python.

Tf-Idf Vectorizer

In scikit-learn, a Tf-Idf Vectorizer is a class that can be used to convert a collection of raw documents (i.e., a list of strings) into a numerical representation, called a Tf-Idf matrix. This matrix can then be used as input to a machine learning model.

Tf-Idf stands for “term frequency-inverse document frequency”. It is a numerical statistic that is intended to reflect how important a word is to a document in a collection of documents.

The term frequency (tf) is the number of times a word appears in a document. The inverse document frequency (idf) is a measure of how rare a word is across all documents. The product of these two values is the Tf-Idf value for a given word in a given document.

The Tf-Idf Vectorizer in scikit-learn converts a collection of raw documents into a Tf-Idf matrix by:

Tokenizing the documents (i.e., splitting them into individual words)
Building a vocabulary of all the words in the documents
Counting the number of occurrences of each word in each document
Computing the Tf-Idf values for each word in each document
Representing each document as a vector of Tf-Idf values
The resulting matrix has one row for each document and one column for each word in the vocabulary. The value at the intersection of a row and a column is the Tf-Idf value for the corresponding word in the corresponding document.

The Tf-Idf Vectorizer can also be used in text classification, clustering, and information retrieval tasks, as it provides a way to convert text into numerical features that can be used as input to machine learning algorithms.

Crontab Examples

A crontab (cron tables) is a configuration file that specifies shell commands to run periodically on a given schedule. The commands in a crontab file (also known as a “cron job”) are executed by the cron daemon, a built-in Linux utility that runs processes on your system at a scheduled time.

Each line in a crontab file represents a separate cron job and follows a specific format, consisting of six fields separated by spaces:

* * * * * command

The fields represent the following:

  1. Minute (0-59)
  2. Hour (0-23)
  3. Day of the month (1-31)
  4. Month (1-12)
  5. Day of the week (0-6, with 0 being Sunday)
  6. The command to be run

The asterisks in the first five fields indicate that the command should be run every minute, every hour, every day of the month, every month, and every day of the week, respectively.

To edit your crontab file, you can use the crontab -e command, which will open the file in a text editor. When you are finished editing the file, save and exit the editor to activate the changes.

Crontab Examples

To run a command at 4:00am every day, the entry in the crontab file would be:

  
0 4 * * * command

To run a command every Monday at 6:00am, the entry would be:

  
0 6 * * 1 command

To run a command every 15 minutes using a crontab, you can use the following entry:

  
*/15 * * * * command

To run a command every 4 hours using a crontab, you can use the following entry:

  
0 */4 * * * command

To run a command at 3:15am every day using a crontab, you can use the following entry:

  
15 3 * * * command

Linux Disk Usage

To display the amount of disk used in Linux in megabytes, you can use the df command with the -h option. This will display a list of all mounted filesystems on the system, along with the total size of the filesystem, the amount of space used, and the available space. The -h option stands for “human-readable”, and it causes the df command to display the sizes in a more readable format (e.g. “1G” for 1 gigabyte).

You can also use the –total option to display a grand total of all used and available space on all filesystems.

  
df -h --total
