  • Padloc, The Open-source Password manager for teams and enterprise that works everywhere

    Padloc is a dead-simple password manager app for users who want to get the job done without any distractions and clutter.

    Padloc is a free, open-source solution but also offers a web service that helps the user to sync and store their passwords and keys in an encrypted web vault for a fee.

    Users also can download and install the app on their machine and sync up to 50 passwords, credit cards info, and login credentials, with up to 2 connected devices.

    However, the project itself is an open-source project that is licensed under GPL-3.0 License, which means you can install its component and run your server.

  • The Apache Software Foundation Announces Open Source data orchestration platform Apache® Hop™ as a Top-Level Project

    The Apache Software Foundation (ASF), the all-volunteer developers, stewards, and incubators of more than 350 Open Source projects and initiatives, announced today Apache® Hop™ as a Top-Level Project (TLP).

    Apache Hop —the Hop Orchestration Platform— is a flexible, metadata-infused data orchestration, engineering, and integration platform. The project originated more than two decades ago as the Extract-Transform-Load (ETL) platform Kettle (Pentaho Data Integration), was refactored over several years, and entered the Apache Incubator in September 2020.

    "We are pleased to successfully adopt 'the Apache Way' and graduate from the Apache Incubator," said Bart Maertens, Vice President of Apache Hop. "Apache Hop enables people of all skill levels to build powerful and scalable data solutions without the need to write code. As an Apache Top-Level Project, Hop is developed and used by people across the globe. Hop's full project life cycle support helps these data teams to successfully build, test and run their projects in ways that would otherwise be hard or impossible to do."

  • QtPass is a free, open-source multiplatform Password manager

    QtPass is an open-source, free password manager GUI for the standard Unix password manager "pass" application.

    The "pass" password manager is a command-line open-source feature-rich application that follows Unix's philosophy.

  • Entrepreneurship for Engineers: Side Business or Full Time?

    Around this time of year people often wonder about their career trajectories and think about goals for the new year. If you’re the creator and/or maintainer of an open source project, you might also be wondering if now is the time to make your part-time open source project a full-time job or continue working on it in your spare time.

    Hearing from other entrepreneurs can be useful in making this kind of decision, but when asked how to determine if something is ripe to go from side hustle to business, the entrepreneurs I spoke with often responded with a version of, “I wish I knew.”

    That’s because whether or not an open source project might be monetizable is one question, whereas whether or not a particular person is going to be able to pull off that shift — and whether that is the best career move at the time, for that person — is another entirely.

  • Another use for the syslog-ng elasticsearch-http destination: Zinc

    There is a new drop-in replacement for Elasticsearch, at least if you don’t mind the limitations and the alpha status. However, it definitely lives up to the promise that it provides an Elasticsearch-compatible API for data ingestion. I tested it with the elasticsearch-http() destination of syslog-ng, and it worked perfectly after I modified the URL in the configuration example I found.
    So, what is Zinc? It is a search engine written in Go that provides an Elasticsearch-compatible API for data ingestion. You cannot use Kibana with it, only its own web interface. If you are not into graphs and dashboards, and want to search text messages, then it is perfect. The application itself is a single binary and it does not have any external dependencies. It is lightweight and easy to configure, as practically there are no configuration options at all.
    Note: Zinc is still in alpha state. There are no guarantees that later versions will be compatible at any level. Error messages can sometimes be cryptic and you might run into unexpected behavior.

Apache Hop Hops To Top-Level Project Status

  • Apache Hop Hops To Top-Level Project Status - Phoronix

    After starting off in development more than two decades ago as Kettle, Apache Hop in its current form has now made it to being an Apache Software Foundation top-level project.

    Apache Hop is an orchestration platform for facilitating both data and metadata orchestration. Apache Hop supports visual development, is lightweight in nature, metadata driven, offers hundreds of plug-ins, and has built-in lifecycle management. Apache Hop originally started out more than two decades ago as Extract-Transform-Load (ETL) platform Kettle.

Arduino Projects: Sun and Power Trackers

  • This sun tracker uses an Arduino to increase solar panel efficiency | Arduino Blog

    With the rapid pace of solar panel installations over the course of the previous decade, there has been an ongoing challenge of trying to improve their efficiency. Apart from the typical silicon crystal photovoltaic cells, there are also more efficient/expensive cells known as concentration photovoltaics (CPV), which rely on a set of mirrors to focus sunlight into a small multijunction cell. Although this technology reduces the size and material requirements, it also requires precise sun tracking for peak performance. Ruediger Loechenhoff has been able to create a far cheaper solar tracker controller, which relies on an Arduino Uno to drive a set of two motors that position the panel. To achieve this, the Uno was connected to a 9-axis MPU-9250 compass module for internal positioning, a DS3231 real-time clock for accurate timing, and a DIY shading beam sunlight sensor to detect optimal angles. Operating the tracker is also quite simple since the firmware only requires an occasional calibration step after a set number of days.

  • This Arduino device can anticipate power outages with tinyML | Arduino Blog

    Our reliance on electronic devices and appliances has never been higher, so when the power goes out, it can quickly become an unpleasant and inconvenient situation, especially for those who are unable to prepare in time. To help combat this problem, Roni Bandini has devised a device he calls “EdenOff,” which is placed inside an electrical outlet and utilizes machine learning at the edge to intelligently predict when an outage might occur. Developed with the use of Edge Impulse, Bandini began by creating a realistic dataset that consisted of three columns that pertain to different aspects of an outlet: its voltage, the ambient temperature, and how long the service has been working correctly. After training a model based on one dataset for regular service and the other for a failure, his model achieved an excellent F-1 score of .96, indicating that the model can forecast when an outage might take place with a high degree of accuracy.

  • Do While – Loop Example in Python | Mark Ai Code

    Loops are an important and widely utilized element in all current programming languages. A loop is the finest solution for automating a certain repeated operation or preventing yourself from writing repetitive code in your projects. Loops are sequences of instructions that are executed repeatedly until a condition is fulfilled. Let’s take a closer look at how Python loops function.

  • Patch now: Zoom chat messages can infect PCs, Macs, phones with malware

    Zoom has fixed a security flaw in its video-conferencing software that a miscreant could exploit with chat messages to potentially execute malicious code on a victim's device. The bug, tracked as CVE-2022-22787, received a CVSS severity score of 5.9 out of 10, making it a medium-severity vulnerability. It affects Zoom Client for Meetings running on Android, iOS, Linux, macOS and Windows systems before version 5.10.0, and users should download the latest version of the software to protect against this arbitrary remote-code-execution vulnerability. The upshot is that someone who can send you chat messages could cause your vulnerable Zoom client app to install malicious code, such as malware and spyware, from an arbitrary server. Exploiting this is a bit involved, so crooks may not jump on it, but you should still update your app.

  • SAP attracts further criticism for Russia presence, despite promise to leave
