Working from home - fun, facts and scares!

Raghavendra Prabhu

Gone are those days when companies used to be strictly colocated in a single office. Distributed workplaces are gradually becoming the norm than an exception. So, it is essential that we talk more about it and discuss it. So, this talk is essentially about: a) Productivity and working from home. b) Scheduling flexibility. c) Challenges in communication and ways to overcome them. d) Ways of getting such a job and Open Source. e) Measuring work and micro-management f) Feeling of detachment and workarounds for it. To sum up, I will make this talk a very informative and entertaining one, as a lightning talk ought to be.

Antonio noticed a fire at a grocery store while walking downtown one night. He promptly ran to the nearest fire alarm box to report it. The firemen arrived soon after and quickly got to work putting out the fire. They fastened a hose to a hydrant and used long ladders and hoses to extinguish the fire in the upper window. In a short time, the fire was put out, saving many lives and property, thanks to Antonio's prompt action and the firemen's quick response.

250,000 incoming first grade students in Metro Manila were required to take the DepEd School Readiness Assessment before the start of the 2007-2008 school year. The assessment aims to measure students' readiness across different domains and identify their competency levels as individuals and as a group. The results will be used to provide appropriate support to address students' academic and non-academic needs in first grade.

Xtrabackup and FTWRL

Raghavendra Prabhu

The document discusses Xtrabackup and FTWRL (Flush Tables With Read Lock). It describes how Xtrabackup works by taking consistent backups without locking tables for long durations. It also explains how FTWRL is used to get a consistent snapshot of databases during backups and replication. The document notes that while locking has benefits, alternatives like no-lock backups are being explored to avoid issues with DDL statements and non-transactional operations during backups. It concludes by inviting questions from the audience.

5 use adverbs of duration in sentences

Here is a 5 sentence paragraph comparing classmates' habits of doing assignments using adverbs of manner and frequency: Some classmates always do their assignments carefully and thoroughly. A few students seldom complete homework on time and often rush through it sloppily. One student occasionally finishes assignments early but rarely puts forth her best effort. Most of us do our work diligently and turn it in daily, though a classmate never seems motivated to put in the necessary effort. While habits vary, we can all benefit from striving to approach assignments wisely and positively.

Securing databases with systemd for containers and services

Raghavendra Prabhu

Data is the most valuable entity associated with a system, particularly when it is a sensitive one. Not only are there threats associated with physical access to the box, but also ones where logical access suffices - sql injections etc. Vulnerabilities like shellshock and heartbleed have also shown that an exploit in one component can also be used to access others through buffer overflows, memory overruns etc. and/or impact the immunity of system severely. This is where "Principle of least privilege" comes into play. Wikipedia defines it as "a particular abstraction layer of a computing environment, every module (such as a process, a user or a program depending on the subject) must be able to access only the information and resources that are necessary for its legitimate purpose".

DEEP LEARNING FOR SMART GRID INTRUSION DETECTION: A HYBRID CNN-LSTM-BASED MODEL

gerogepatton

As digital technology becomes more deeply embedded in power systems, protecting the communication networks of Smart Grids (SG) has emerged as a critical concern. Distributed Network Protocol 3 (DNP3) represents a multi-tiered application layer protocol extensively utilized in Supervisory Control and Data Acquisition (SCADA)-based smart grids to facilitate real-time data gathering and control functionalities. Robust Intrusion Detection Systems (IDS) are necessary for early threat detection and mitigation because of the interconnection of these networks, which makes them vulnerable to a variety of cyberattacks. To solve this issue, this paper develops a hybrid Deep Learning (DL) model specifically designed for intrusion detection in smart grids. The proposed approach is a combination of the Convolutional Neural Network (CNN) and the Long-Short-Term Memory algorithms (LSTM). We employed a recent intrusion detection dataset (DNP3), which focuses on unauthorized commands and Denial of Service (DoS) cyberattacks, to train and test our model. The results of our experiments show that our CNN-LSTM method is much better at finding smart grid intrusions than other deep learning algorithms used for classification. In addition, our proposed approach improves accuracy, precision, recall, and F1 score, achieving a high detection accuracy rate of 99.50%.

IJECEIAES

Climate change's impact on the planet forced the United Nations and governments to promote green energies and electric transportation. The deployments of photovoltaic (PV) and electric vehicle (EV) systems gained stronger momentum due to their numerous advantages over fossil fuel types. The advantages go beyond sustainability to reach financial support and stability. The work in this paper introduces the hybrid system between PV and EV to support industrial and commercial plants. This paper covers the theoretical framework of the proposed hybrid system including the required equation to complete the cost analysis when PV and EV are present. In addition, the proposed design diagram which sets the priorities and requirements of the system is presented. The proposed approach allows setup to advance their power stability, especially during power outages. The presented information supports researchers and plant owners to complete the necessary analysis while promoting the deployment of clean energy. The result of a case study that represents a dairy milk farmer supports the theoretical works and highlights its advanced benefits to existing plants. The short return on investment of the proposed approach supports the paper's novelty approach for the sustainable electrical system. In addition, the proposed system allows for an isolated power setup without the need for a transmission line which enhances the safety of the electrical network

Advanced control scheme of doubly fed induction generator for wind turbine us...

IJECEIAES

This paper describes a speed control device for generating electrical energy on an electricity network based on the doubly fed induction generator (DFIG) used for wind power conversion systems. At first, a double-fed induction generator model was constructed. A control law is formulated to govern the flow of energy between the stator of a DFIG and the energy network using three types of controllers: proportional integral (PI), sliding mode controller (SMC) and second order sliding mode controller (SOSMC). Their different results in terms of power reference tracking, reaction to unexpected speed fluctuations, sensitivity to perturbations, and resilience against machine parameter alterations are compared. MATLAB/Simulink was used to conduct the simulations for the preceding study. Multiple simulations have shown very satisfying results, and the investigations demonstrate the efficacy and power-enhancing capabilities of the suggested control system.

Understanding Inductive Bias in Machine Learning

SUTEJAS

This presentation explores the concept of inductive bias in machine learning. It explains how algorithms come with built-in assumptions and preferences that guide the learning process. You'll learn about the different types of inductive bias and how they can impact the performance and generalizability of machine learning models. The presentation also covers the positive and negative aspects of inductive bias, along with strategies for mitigating potential drawbacks. We'll explore examples of how bias manifests in algorithms like neural networks and decision trees. By understanding inductive bias, you can gain valuable insights into how machine learning models work and make informed decisions when building and deploying them.
