Synopsis In this episode Rho`n records his further adventures in installing GuixSD onto a Mac Mini computer. Guix has a graphical text based installer. It is reminiscent of the mid to late 90s Debian installers. Even with its old school feel, the installer is very nice. It is well laid out, has good onscreen description for each step of the installation process, and provides ample configuration selections from language, to to key board layout, to desktop and software selection.

This show has been flagged as Clean by the host. In this nostalgic episode, I share my personal experiences riding and flying light aircraft during the 1980s and 1990s. From the hum of a Cessna engine to the grace of a Bonanza slicing through the clouds, it’s a journey through the skies filled with stories of daring, faith, and the wonder of flight. Topics Covered: Light Aircraft Overview General insight into what qualifies as light aircraft and why they’re beloved by private pilots and hobbyists. Light aircraft – Wikipedia Flying in a Cessna Memories of flying in various models of the iconic Cessna—dependable, nimble, and a staple of personal aviation. Cessna – Wikipedia Bonanza Adventures Experiences flying in the Beechcraft Bonanza, known for its sleek design and comfort—especially memorable during cross-country flights. Beechcraft Bonanza – Wikipedia Missionary Aviation Stories Recollections of missionary pilots and their vital roles in reaching remote areas, often relying on small aircraft to deliver aid, supplies, and hope. Missionary aviation – Wikipedia Aviation in the 1980s and 1990s A look back at the culture of general aviation during this era—before GPS was common, when flight was guided more by instinct, skill, and charts on your lap.

HPR4384: Browser and dedicated apps on the mobile phone

לפני 13 ימים

—

This show has been flagged as Clean by the host. Recently I had a discussion on Mastodon about mobile phone applications. The other person stated "the web belongs to web browsers". I agreed to it as a general good approach. Some dedicated apps cannot be substituted with the browser, but some can. I do not have so many apps myself, but anyway that statement got me to review a couple of my apps how they works in the Firefox browser. And actually, I could delete three apps and all functions I needed from them can be managed from Firefox. Beside traditional bookmarks, those pages can be pinned to the Firefox start page or placed like a webapp on the mobile screen, so they look like an ordinary app. Using the Firefox browser makes it easier to control the privacy. In addition to what is built into Firefox, I currently also have the two extensions, Privacy Badger and uBlock Origin in my Firefox browser. Beside privacy and in general to be somewhat more in control, this approach also reduces the number of apps to keep updated and reduce storage need. Sometimes apps are necessary of otherwise beneficial. But I think the traditional browser should not be forgotten also on the smart mobile phone. Provide feedback on this episode .…

HPR4382: Understanding Antenna Gain and the Decibel scale

לפני 15 ימים

—

Power Measurement and Antenna Gain HPR show by Paulj, May 2025. 1.0 Power expressed in dB (also written as dBW) Power PdB = 10 . log10P Where P is the power expressed in Watts. 2.0 Power expressed in dBm Power PdBm = 10 . log10P Where P is the power expressed in milliwatts. 1W = 1000mW Power PdBm = 10 . log101000mW Power PdBm = 30 dBm so: 0 dB = 30 dBm 3.0 Power expressed relative to an isotropic antenna - dBi An Isotropic antenna is an theoretical ideal antenna which radiates equally in all directions. Imagine the antenna is at the centre of a sphere, the signal strength at the surface of the sphere is equal at all points. The gain of an isotropic antenna is defined as 1, meaning: 10 dB = 10 dBi 4.0 Power expressed relative to a half wave dipole antenna - dBd The simplest practical antenna is a half wave dipole antenna, where each of the two legs is a quarter wave length long. The feed is at the centre, and the two legs are generally horizontal, and aligned away from the feed point 180 degrees apart. The dipole antenna exhibits gain perpendicular to the legs. The maximum gain is 1.64 times the isotropic antenna - a gain of approximately 2.15dBi. The gain off the ends of the dipole is much lower - the total power radiated by the antenna can not exceed the power being input, so if there is more radiation (gain) in one direction, there must be a corresponding reduction in a different direction. So: 2.15 dBi = 0 dBd 5.0 Effective Radiated Power - ERP and EIRP ERP and EIRP are both used to indicate the power achieved using an antenna.ERP compares the antenna performance with a dipole, and EIRP compares the performance with an isotropic antenna. So, the ERP is the power which would need to be fed into a dipole antenna, to get the same effect in the direction your antenna is pointing. EIRP is the power required for an isotropic antenna to gain equivalence. Practical example: My KX3 can transmit 15W. using the formula above, this is 11.77 dB. If I attach a Yagi-Uda antenna with a gain of 10dB, the ERP is 21.77 dB. Using the formula above, from this number you can calculate that this is the equivalent of 150.3142 Watts ERP. To understand the EIRP, we need to add 2.15 to the 21.77 dB value, giving 23.92 dB EIRP. Again, converting to actual power gives 246.515 Watts EIRP. If you are comparing antennas, make sure the same units are being used in all cases (either EIRP or ERP) - some sellers will use EIRP, because the values are higher! Check your licence conditions. Power output limits are often at the antenna, and don't include antenna gain. You can set your transmitter to output sufficient power to overcome any feed line losses, and present up to the power permitted to the antenna. A good antenna can then be used to get the transmitted power out and across the world. For feedline loses, the value is given in dB per 10 metres. For example, RG58 is 2dB / 10 metres (at…

Isaac Asimov began with the Foundation series, but then added to it. Early on, he wrote what are called the Empire novels which are prequels to the rise of Trantor. Then he decided to tie his Robot series into his Foundation series. So now we will take a look at these remaining novels.

The aim of this research isn't about debating the quality of these products—it's assumed that with thousands of employees, these services meet most quality expectations. Instead, the focus is on the critical implications of widespread dependency and potential risks related to service interruptions or supply chain attacks. Why is this important? Supply Chain Attacks : High dependency means higher vulnerability to targeted disruptions. Business Continuity : Significant risks were illustrated by incidents such as the CrowdStrike outage in July 2024 , which forced Brussels Airport back to pencil-and-paper operations temporarily. My Research Approach: Primarily, I analyze the DNS MX records of municipalities: MX records typically reveal if mail services are hosted on Microsoft (Office 365/Exchange Online) or Google (Workspace). A high probability that using these providers for email also means municipalities likely depend on the respective cloud office suite (e.g., Word/Excel/SharePoint or Docs/Sheets/Drive). Preliminary Observations: Belgium, Finland, Netherlands : Over 70% of municipalities rely heavily on Microsoft mail services, a significant warning sign of dependency. Germany, Hungary : Fewer than 5% of municipalities use Microsoft or Google explicitly via MX records, though caution is necessary. Here’s why: Challenges Identified: Local MS Exchange Servers : Municipally hosted local installations aren't externally identifiable via MX records. Mail Proxies : Some municipalities use mail proxy services (spam/phishing filters) obscuring the actual mail service used behind proxy domains. Techniques Tested: SPF Records : Often reveal the underlying email service, though they may contain outdated information, lowering reliability. Telnet EHLO Commands : Municipalities commonly obscure their SMTP headers, limiting usefulness. Cloud Provider IP-Ranges : Investigating if mail servers run on Google, Amazon, or Azure infrastructure. Even if identified, this alone doesn't clarify if proprietary or replaceable services are used. TXT Records : Occasionally contain subscription keys or mail-related settings (e.g., MS subscriptions, Mailjet), but again, could be historical remnants. Unfortunately, none of these get to show me all of the third party services. Community Call: I'm reaching out to listeners and the broader community for ideas or techniques on reliably fingerprinting the actual digital service providers behind mail servers. Specifically: How to accurately determine if servers run Microsoft or Google services ? Any ideas to detect deployments of Nextcloud or similar open-source alternatives?
