• Nmap is a free, open-source network scanning tool widely used by network administrators to discover vulnerabilities and perform network discovery. Nmap can scan for live hosts, identify services running on those hosts, and determine the host’s operating system. Nmap can also scan for specific vulnerabilities, such as unpatched software or open ports.

• Additionally, Nmap can be used to gather information about a network, such as its layout or the types of devices connected to it. While Nmap is a potent tool, it is essential to note that it can be misused. In the hands of a skilled attacker, Nmap can be used to launch attacks against systems or to gather sensitive information about a network. As a result, it is essential to use Nmap responsibly and only with permission from the system owner.

Debian Family

=> ↺ Best 15 Debian-based Linux Distributions – TREND OCEANS

• The difference can be major, depending upon the maintainer of the distribution. For example, Ubuntu is a Debian-based distribution maintained by Canonical. However, Ubuntu is geared more towards user-friendliness and has a more corporate feel. On the other hand, Debian is more concerned with software freedom and options.

• Even the installation part of Ubuntu is more user-friendly than the installation of Debian, although they both share the same structure.

• Remember, Ubuntu is not the only distribution in the race to provide you with a rich and dynamic user experience with advanced tools and applications.

• Today, you will learn about the 15 best Debian-based Linux distributions, which might include your next favourite distribution.

Devices/Embedded

=> ↺ STEPFPGA FPGA board is programmable with a Web IDE (Crowdfunding) – CNX Software

• STEPFPGA MXO2Core miniature FPGA development board is based on Lattice MXO2-4000 FPGA, and designed for education with an easy-to-use Web IDE, instead of the more traditional tools that can be frustrating to use, and detailed tutorials.

• The board also comes with a 2-digit segment display, some LEDs, push buttons, and a 4-way DIP switch, as well as two rows of twenty pins for I/O expansion, and a USB Type-C port used for power, programming, or mass storage.

Open Hardware/Modding

• Geehy APM32F103 is a clone of STMicro STM32F103 MCU that has been tested by at least one person who claims it was just a drop-in replacement and PCB, code, hex, testing, and production did not have to be changed at all.

• Most STM32 microcontrollers are in short supply with 52+ weeks lead times and prices going through the roof, so people may be looking into the long list STM32 clones and fakes including APM32F103.

Free, Libre, and Open Source Software

Productivity Software/LibreOffice/Calligra

Security

Privacy/Surveillance

=> ↺ Digital Transparency: A Right to Information Report for June 2022

• For the month of June 2022, IFF has filed 21 Right to Information (“RTI”) applications and 14 first appeals. In a response to the RTI application on the current status of the Aarogya Setu Data Access and Sharing Protocol, 2020, the Ministry of Electronics and Information Technology (‘MeitY’) responded that it had been discontinued since May 10, 2022. It also stated that the Empowered Group on Technology and Data Management – which notified the protocol in May 2020 was dissolved in September 2020.

• [...]

• One of our key areas of work is ensuring that public authorities respect data privacy and engage in practices which will ensure that the right to privacy is protected. We filed 10 RTI applications with various authorities this month to ask for information pertaining to projects which affect the data privacy of Indian citizens.

• Under IFF’s Project Panoptic, we routinely file RTI applications with various public authorities after we come across news reports that they are developing or using facial recognition technology (FRT). This month, we filed an application with the Bangalore Metro Rail Corporation Limited over their proposed use of facial recognition on the people using the metro services.

• For more information on the use of facial recognition technology and how it increases mass surveillance, visit IFF’s Project Panoptic.

Environment

Wildlife/Nature

=> ↺ Rubenerd: The Willie Wagtail

• Any time I see a cute bird as Wikipedia’s featured picture, I have to share it. This is a Willie wagtail, taken by JJ Harrison in Lithgow, about a hundred kilometres north-west from where I am in Sydney. It probably flew away by now.

Finance

=> ↺ Interest rates in 2022

• Interest rates are used, theoretically, to encourage or discourage demand. But to use a tech analogy, I feel like we’re operating a black box right now, and with completely different inputs. We’re in uncharted waters.

Censorship/Free Speech

=> ↺ Global Coalition of NGOs: Repeal MR5 and its amendment MR10 – Access Now

• Note: Access Now co-signed this statement along with 8 other organizations from around the world in calling on Indonesia’s Minister of Communication and Information to repeal MR5 and its amendment, MR10— both regulations contain content moderation provisions which are inconsistent with internationally-recognized human rights, including freedom of expression and opinion.

Gemini* and Gopher

Personal

=> ↺ The Dark

• Went up to SBUX to get out of the house even though nobody is home. If I stayed there, I probably would not have given myself time to write. So I set a timer for 60 minutes before I can leave.

• Now that I’ve done that, I can’t think of much to write about, so if this becomes garbage, you have been warned.

• Right now, I feel so out of touch with everything that has been going on in the world, in the communities I frequent, with my friends, with my family. This has been probably over the past month or so. There is a built-in safety mechanism that gets tripped when I become unwell and have exceeded my limitations to cope. I put myself in the dark, shields up, red alert! I know it is a safe place, but I do not like to go there. It has been years since I had to go there and it feels wretched being there, but I know it is safe.

Technical

Programming

=> ↺ Good book, bad language

• That is legit. I’ve learned a lot from books about languages that aren’t necessarily my fave languages, like Smalltalk, Perl, and even COBOL.

• Books like Design Patterns, Principles of Program Design, and Deep C Secrets comes to mind,

• Sometimes people who are stuck in a bad language need to develop discipline or structure or formalize their thinking since otherwise they’d be lost (since their language doesn’t let them create abstraction) and that can be interesting. It can also help us in langages that do have good metaprogramming facilities; there’s this old adage that most of the patterns in Design Patterns are like one line of Lisp (for example, why do you need Template Method or Visitor when you can just pass a proc🤦🏻‍♀️) but sometimes it can help you know what that line should be.
