  • Dell is bringing Thunderbolt 3 support to Linux systems

    The Dell XPS 13 is one of our favorite laptops, but that’s only if Windows is your operating system of choice. Mac users have a whole brand just for their computers, but Linux aficionados are typically left out in the cold. There’s good news today though, as the XPS Developer Edition, which runs a custom Ubuntu image, will bring support for Thunderbolt 3 to the platform with the Skylake update, according to chatter on the Dell forums, as pointed out by PCWorld.

  • dgplug summer training student Trishna Guha

    This training has changed my life entirely. I started the training as a newbie. I took part in the training attentively and tried to learn and implement what all have been taught in the summer training. After few months I really could feel the change. I jotted down the skills those I didn’t used to have before the training and it felt so awesome. Finally this training has turned me into an Open Source Contributor Smile. I am learning a lot contributing to opensource.

  • Last week 'flu by

    My first chore was to set up VPN access to the development resources (source control, wiki, etc.). I sandboxed the proprietary VPN client in a VM with a systemd unit to run it at boot, so I can control it by starting and stopping that VM. I then set to work on unpacking and exploring the SoC vendor's evaluation module (EVM), starting by looking at serial output - of which there was none. Nothing on the LCD panel or network port either. A frustrating day.

  • FAQ: What the heck happened to Linux Mint?

    Apparently, a hacker going by the handle “Peace.” Peace gave an interview to ZDNet reporter Zach Whittaker, in which he or she explained that the idea was mainly just to get access to as many computers as possible, possibly for a botnet. Peace first gained access to the site in January, via a security vulnerability in a WordPress plugin.

This week in KDE: And now time for some UI polishing

This week we’ve mixed in a lot of user interface polishing with our usual assortment of bugfixes! 15-Minute Bugs Resolved Current number of bugs: 57, down from 59. 0 added, 1 found to already be fixed, and 1 resolved: When using screen scaling with the on-by-default Systemd startup in Plasma, the wrong scale factor is no longer sometimes used immediately upon login, which would cause Plasma to be blurry (on Wayland) or everything to be displayed at the wrong size (on X11) (David Edmundson, Plasma 5.25.2) Read more Also: Weekly Updates on GCompris : 1

ROMA Linux laptop to feature quad-core RISC-V SoC, support Web3, NFT, cryptocurrencies, etc..

ROMA is an upcoming Linux laptop equipped with an unnamed quad-core RISC-V processor with GPU and NPU, up to 16GB RAM, 256GB storage, primarily aimed at software developers, and with Web3 technology integration. The ROMA laptop will be born out of the collaboration between DeepComputing working on engineering and Xcalibyte taking care of system tuning, plus PW (assembly), ECP (security), XC (crypto), Rexeen (voice), and the LatticeX Foundation (PoS blockchain, NFT).

  • Logistic Regression in R

    In data science and Statistics, it is a regression model if the dependent variable results in categorical values like True/False, Yes/No, or 0/1. Usually, the logistic regression model is binomial. However, it can be extended. It measures the probability of the successfulness or failure of an event as a dependent variable which is based on a mathematical equation. This equation relates the dependent variable (response variable) with the independent variables (predictor). We can say that logistic regression is a generalized form of linear regression but the main difference is in the predicted value range is (-∞, ∞) while the range of predicted value in logistic regression is (0,1). In this post, we will learn about logistic regression and how to implement it in the R programming language.

  • The new learntla is now online!

    One lesson I’ve learned the hard way is that keeping lots of assets in sync is an absolute nightmare. So this version has a lot more software managing that for me. In particular, I built a pipeline for handling spec assets. I have several XML spec templates that represent “sequences of iterations” on a spec. A python script unpacks the template into a set of .tla files. After I put in appropriate metadata, a second script cleans up each spec into a “presentable” form, loads the metadata into the appropriate files, and places the asset in the appropriate path.

  • Generate Array with elements in given range and median as K

    Given two integers N and K and a range [L, R], the task is to build an array whose elements are unique and in the range [L, R] and the median of the array is K.

  • C++ Program to check if two Arrays are Equal or not

    Given two arrays arr1[] and arr2[] of length N and M respectively, the task is to check if the two arrays are equal or not.

  • Seaborn Regplot

    Seaborn is a Matplotlib-based visual analytics library. It has a high-level framework for defining the visually appealing analytical graphs. Matplotlib package is the foundation of the Seaborn module. To visualize the statistics and regression analysis, we use the regplot() function. To evaluate the regression model, there are many other interrelated contradictory approaches. Whenever the predicted output is a continuous as well as a cumulative value, it is referred to as a prediction model. Numerous other approaches can be employed. The most basic of which is the linear model. It integrates the values to the optimal higher dimensional space that passes through all of the vertices. The regplot() function is used to create the regression plots. Regression Analysis is a technique used for evaluating the associations between one or more independent factors or predictors and the dependent attributes or covariates. The variations in the requirements in correlation to modifications in specific determinants are analyzed through the Regression Analysis. The criteria’s declarative requirement is dependent on the indicators, which give the new value of the dependent attributes whenever the data points are updated. Evaluating the intensity of covariates, anticipating an outcome, and estimating are the three important applications of a regression model.

  • Seaborn HeatMap Colors

    Heatmaps are colored maps that display data in a two-dimensional format. Color variation is achieved by using hue, saturation, or brightness to portray the varied information on the color maps. This color variation provides the readers with visual information about the size of quantitative values. Heatmaps substitute numbers with colors since the human mind understands views better than the textual data. Considering that humans are primarily visual, it makes sense to present the data in any manner. Heatmaps are simple-to-understand visual representations of data. As a result, data visualization tools like Heatmaps are becoming increasingly popular. Heatmaps are used to display patterns, variance, and anomalies, as well as to depict the saturation or intensity of the variables. Relationships between variables are depicted via heatmaps. Both axes are used to plot these variables. By observing the color shift in the cell, we can look for the patterns. It only takes numerical input and shows it on the grid, with different data values displayed by the varying color intensity. Many various color schemes can be used to depict the heat map, each with its own set of perceptual advantages and disadvantages. Colors in the Heatmap indicate patterns in the data, thus the color palette decisions are more than just cosmetic. The finding of patterns can be facilitated by the appropriate color palettes but can also be hindered by the poor color choices. Colormaps are used to visualize heatmaps since they are a simple and effective way to see data. Diverse colormaps could be utilized for different sorts of heatmaps. In this article, we’ll explore how to interact with Seaborn heatmaps using the colormaps.

  • How To Do Train Test Split Using Sklearn In Python

    In this article, let’s learn how to do a train test split using Sklearn in Python. Train Test Split Using Sklearn The train_test_split() method is used to split our data into train and test sets. First, we need to divide our data into features (X) and labels (y). The dataframe gets divided into X_train,X_test , y_train and y_test. X_train and y_train sets are used for training and fitting the model. The X_test and y_test sets are used for testing the model if it’s predicting the right outputs/labels. we can explicitly test the size of the train and test sets. It is suggested to keep our train sets larger than the test sets.
