Powerful open source SQLite manager for Raspberry Pi

SQLite is a lightweight but powerful database management tool. It occupies a little space on the device – a bit more than 500KB, but offers most of the features implemented on other SQL database tools. SQLite is a serverless engine, meaning that the whole database is stored in a single file, and all transactions are reads and write from the file. There are no initial server configurations required – all you need is to create a .db file and start writing queries. This is why SQLite is preferred on small devices like mobile phones, embedded devices, and Raspberry Pi. Previously, we have installed an SQLite into Raspberry Pi, created a database and table with only a few lines of script. We performed all the tasks from the command-line tool. Eventually, you will want to have full control of the database and see the whole picture. Therefore, you should also consider installing SQLite manager, which brings a graphical user interface to work with SQL databases. To run the SQLite manager, you will need to work from the Raspberry Pi desktop. You may want to connect a monitor or use a VNC client to access the Raspberry Pi desktop like me. VNC…

All Things IoT

Unless you’ve been living under a rock, you must have heard about IoT. But, do you know what exactly IoT is? In the simplest terms, IoT or Internet of Things refers to the network of connected devices capable of collecting and sharing data across the network. Over the past few years, IoT has grown in popularity, and it’s believed that about 33 billion devices will be connected to IoT by 2020. But, we will not talk about why IoT is important or why it has grown in popularity. Rather, the focus of this article is IoT applications. So, let’s dive into a few applications of IoT by industry. Internet of Things Home Innovation Imagine a world where people’s homes could listen to them, talk to them and make decisions. In fact, this is already happening. Connected devices inside homes allow you to control your appliances like lights and HVAC with smartphones. There are more advanced options, too, such as smart refrigerators. Have you heard of Amazon Alexa? It’s an IoT device capable of performing various tasks such as calling an Uber, ordering items for you from Amazon.com, and playing music.

How to Protect Your Business’s Computer Network

Your business needs a computer that is connected to a network, or in other words, the internet. Think, for a moment, about all of the benefits that you would obtain from doing this. You would be able to communicate with your clients, customers, and prospective employees daily. Not to mention, it allows you to have a presence on the world wide web, improving your credibility as a company. So, you decided to set up a computer network, but have you thought about what you need to do to protect it? To safeguard yourself against cybersecurity attacks and to keep your connection secure, you must adhere to the following steps. Monitor by installing a firewall A firewall is a software that people use to protect their private network security. It is precisely for this reason that it should be one of the first steps people take to safeguard their networks, which they must have turned private, to begin with. You don’t want unauthorized users to access your internet, right? That is why a firewall can act as a defense against this, as it can monitor and prevent security breaches at the same time.

Scale up Big Data mining with Hadoop machine learning tools

Each human or organization doing various activities are constantly generating massive amounts of data. In real life, when you visit supermarkets, doctors, institutions, log into a bank account, visit webpages, spend time in social networks, buy online – you leave a footprint of data. The data of your past carries lots of interesting information about your human habits, interests, behavior patterns. If we scale up to organizations, where every process and decision play a significant role in business success, data becomes a valuable asset. Collected and properly mined historical data may help make critical decisions for the future, optimize the structure, and even see the business trends. Hadoop machine learning tools Big Data is everywhere and, so storing analyzing it becomes a challenge. No human can handle and effectively analyze vast amounts of data. This is where machine learning and distributed storage comes in handy. Hadoop machine learning is an excellent concept for dealing with large amounts of data. The Apache-based Hadoop platform is based on open source tools and utilities that use a network of lots of computers to store and process large amounts of data more efficiently. Hadoop machine learning has joined the concept of different tools. Hadoop…

Tripod The relation between a camera and a tripod is inseparable. Tripods can help you in capturing photos where you require the help of another person. Moreover, they are also used in sports photography, astrophotography, and time-lapse videos and capture long exposures. With a tripod, you will achieve excellent stability and get correctly focused photos by avoiding the camera blur. 2. Extra Battery Imagine you are in long event photography, and suddenly your camera shuts down. It is frustrating to stop taking photos in the middle of the event. Having extra batteries in your bag allows you to keep shooting, and in the meantime, you can also charge the drained one. There are many Online stores where you can buy spare batteries online at discounted prices.

ABCD method for screening skin cancer

To improve diagnostic accuracy, the ABCD rule of lesion screening is widely used, which is based on asymmetry (A), border (B), color (C), and differential structure (D) measuring. • A total dermatoscopic value (TDV) results from the calculation TDV = A·1,3 + B·0,1 + C·0,5 + D·0,5 • This score contributes to the differentiation between benign and malignant lesions: 1,00 – 4,75 – benign skin lesion 4,75 – 5,45 – suspicious More than 5,45 – melanoma Asymmetry A – Asymmetry of Shape, Structure, and Color. The skin lesion is divided into four regions, and symmetry is inspected across the x or y-axis. If asymmetry is only by one axis, it gives 1 point, and if on both axes, there are 2 points calculated. So for shape, structure, and color, there can be 6 points maximum.

What exactly is a Laboratory Information Management System?

Simply put, a Laboratory Information Management System (LIMS) is software that allows the effective management of test results, and samples (and their associated data) to improve lab productivity. By adopting the use of a LIMS, your lab can integrate instruments, automate workflows, and manage samples and associated information. Plus, as well as producing reliable results more quickly, you can also track data from sequencing runs over time (and across experiments) to improve efficiency. This kind of software helps standardize tests, workflows, and procedures. At the same time, it allows the provision of accurate controls (such as test limits) of the process itself. You can also integrate instruments into the LIMS to automate the collection of test data. This eliminates the need to manually transfer results between the instrument and the LIMS solution, eliminating typographical errors. Entering numbers by hand typically results in a 1-3% error rate, and forces all results to be manually validated and approved, taking additional time and resources. The LIMS can be set up to ensure that only results from calibrated instruments may be recorded in the system and, via unique login, to check that the person, entering the results, is adequately trained in the operating procedures to…
