This show has been flagged as Clean by the host. Hello, again. This is Trey. Welcome to part 6 in my Cheap Yellow Display (CYD) Project series. Thank you for hanging in there with me on this rambling series. If you wish to catch up on earlier episodes, you can find them on my HPR profile page https://www.hackerpublicradio.org/correspondents/0394.html To review, my project is to build a portable morse code "Keyer memory" which can be connected to any of my amateur HF transceiver radios by simply plugging it in to the code key input port. This is based around an ESP32 platform which comes prepackaged on a yellow PC board with a color touchscreen display, WIFI, and Bluetooth. We fondly call this contraption the Cheap Yellow Display. So far, I have defined the necessities, collected the required hardware, and failed miserably building the graphical user interface (GUI). While I sort out the technical challenges getting my GUI code to play nicely with the CYD's touchscreen, it is important that we spend some time discussing Morse code itself, and the timing standards we will need to follow. I am not going to dive too deeply into the history behind telegraphs and Morse code, but it is very interesting. If you want to learn more, Wikipedia has the origins and evolution written out quite nicely at https://en.wikipedia.org/wiki/Morse_code For our purposes, we will fast forward from the year 1820 (When telegraphy began) all the way to 1865 when the International Telecommunication Union (ITU) standardized, what it called "International Morse Code". When I say Morse Code for the remainder of this podcast, I am referring to this ITU International Morse Code. Morse code typically includes the following characters: The 26 letter basic Latin alphabet The Indo-Arabic numerals 0 to 9 There is also a single accented Latin letter (É), which is written as an E with an accent mark, and a handful of punctuation marks. These characters are encoded using a sequence of short and long signals. Each short signal is referred to as a dit . Each long signal is referred to as a dah . At a young age, I began to refer to them as dots and dashes, as this is how they are usually written. For example, the letter "A" consists of a single dit followed by a single dah. When written out this would look like a period followed by a hyphen (what some might call a minus sign) .- This encoding method allows messages to be sent by turning on and off an electrical signal. This could result in a light flashing or a tone sounding to the pattern of the signal. The timing of a dit and dah, along with the spacing between them is carefully defined. Morsecode.world does a great job explaining the timing, and you can find their explanation at https://morsecode.world/international/timing/ It all starts with the dit, or more accurately, the amount of time the dit signal is turned on. We will call this length of time 1 unit. We will get to the actual length of time for a unit later in this episode. For now, it is just one unit. So, if a dit is 1 unit long, a dah will be 3 units long, so there is an obvious and consistent difference between a dit and a dah. Also, empty space between elements of the same character is 1 unit long. The space between characters should be 3 units long. Let's demonstrate using the letters H, P, & R. An "H" would be 4 dits …. A "P" would be 1 dit followed by 2 dahs and ending with 1 dit .--. An "R" would be 1 dit followed by 1 dah and ending with 1 dit .-. Remember when we send these grouped together like a word, we need 3 units of spacing between each character. You can hear this now. This is Morse code for the letters "HPR" at 15 words per minute .... .--. .-. That is the perfect segue to the next section, words per minute. The speed of morse code is measured in "words per minute". But how do you calculate this when some characters are short (Like the letter "E" which is only a single dit long), and other characters are long (Like the letter "J" which starts with a single dit and is followed by 3 dahs)? And that's just letters. What about words? We have short words and long words. How can we standardize on words per minute with so much diversity of length? Well, thanks to the French, we have a quite elegant solution to this problem. Well, not the French in general. Just PARIS. PARIS is the standard word which has been agreed upon to be used for determining the speed of Morse code. The word PARIS is 50 units long. "P" = dit(1) + (1) + dah(3) + (1) + dah(3) + (1) + dit(1) = 11 units {Space between letters} = 3 units "A" = dit(1) + (1) + dah(3) = 5 units {Space between letters} = 3 units "R" = dit(1) + (1) + dah(3) + (1) + dit(1) = 7 units {Space between letters} = 3 units "I" = dit(1) + (1) + dit(1) = 3 units {Space between letters} = 3 units "S" = dit(1) + (1) + dit(1) + (1) + dit(1) = 5 units {Space between words} = 7 units 11+3+5+3+7+3+3+3+5+7 = 50 units Here is the word PARIS sent at 15 WPM .--. .- .-. .. ... Morsecode.world again does a great job explaining the maths for how many milliseconds long a dit should be for a specific WPM of code ( https://morsecode.world/international/timing/ ) But, no... We could not keep it that simple. Some guy named Donald R. "Russ" Farnsworth had to complicate things and increase the gaps between letters and words to make interpreting code much easier. There are even more maths for Farnsworth timing... Wait a minute. When did I start saying "Maths" instead of "Math" like a normal North American? What is the reasoning around pluralizing "Math" anyways? Which way is more original English, "Math" or "Maths"? This sounds like a show idea for someone other than me. If you know or are interested in researching it, I look forward to listening to your show in the future. ANYWAYS, there IS much more MATH about Farnsworth timing on another page on Morsecode.world. ( https://morsecode.world/international/timing/farnsworth.html ). But I don't want to get into all of it in detail here. Not when there is a shortcut we can use in our code. Simplified, we can take 1,200 and divide it by the WPM we desire, and it will give us a close enough approximation of the number of milliseconds long a dit should be. For the 15 WPM messages you have heard throughout this episode, a dit was 1200/15 = 80 ms in length. If I speed it up to 20 WPM (The speed at which I try to practice) a dit will be 1200/20 = 60 ms long. This will be an important calculation for us as we develop the code we will later be using to construct our messages using the CYD. And this is also a good stopping point so that I can get back to trying to build that infernal GUI. Provide feedback on this episode.

Message To effectively communicate an event it's important to convey the answers to Who? , What? , When? , Where? , and Why? The Five Ws is a checklist used in journalism to ensure that the lead contains all the essential points of a story. As far back as 1913, reporters were taught that the lead should answer these questions about the situation being reported. https://en.wikipedia.org/wiki/Five_Ws What?, When?, Where? The first sentence is always This is Hacker Public Radio episode (show id) for “(day of week)” the “(day number)” of “(month and year). Saying the name of the show at the beginning of an episode is called establishing brand recognition . It is standard for podcasts, TV and Radio shows as well as on broadcast networks, not to mention the pre-rolls in a movie. We started to do it because some of our Visually Impaired users appreciated knowing what show is playing. Now the same reason can be applied to everyone as the use of visual controlled User interfaces have diminished. Most people control the playlist with headset or voice controls. Saying the show id, and date is common where there are a lot of episodes eg: news or weather shows. It is often skipped where the content is sufficient to identify the episode, eg “the last episode of the foo bar baz podcast, or the last Saturday Night Live” We include the show id and date to allow the listener to refer to the episode easily. As we have literally thousands of shows, we need to help people identify which show they are now listening to, so that it can be easily shared, or commented on. What? Why? We always include Today's show is entitled. (title) . If the episode is part of a series then we also include It is part of the series (series name) . We always include the show (synopsis) . This tells the listener what the show is about. It allows them to skip the episode if they wish. They may wish to do this for many reasons, for example: because they are not interested in the topic, they wish to listen to it while in front of a computer to reference the accompanying show notes, they are listening in public and the topic might not be appropriate. Who? The next part will either be It is the first show by new host (host name) , It is the (multiple of 10)th show of (host name) , or It is hosted by (host name) We are required by the Creative Commons Attribution-ShareAlike 4.0 International (CC BY-SA 4.0) license to credit our hosts, so we do. We think it's important to highlight new hosts especially, so our community we encourage them to continue to contribute. It's also nice to call out hosts who have been contributing a lot by highlighting each 10th show they send in. Where? We always include and is about (minutes)minutes long to give people an idea of how long the show is. Normal broadcasts have to fit neatly into a standard TV/Radio Broadcast schedule. Many podcasters now follow the same tradition of having episodes of a predictable length. Eg: 30 minutes or an hour. On HPR, there is no restriction on how long the show can be so it's desirable to give the listener a way to know how long the episode is so they can plan accordingly. Warning We always include either It carries a clean flag or It carries an explicit flag . This is also common for broadcasts where they are dealing with a topic that may be disturbing to some people.

This show has been flagged as Explicit by the host. A two-part conversation about what it's really like being a woman in tech for almost three decades. Content Warning: The F word probably makes an appearance multiple times. In this episode, Lee sits down with Elsbeth to talk about her long, winding, sometimes ridiculous, often inspiring journey through the IT industry — starting all the way back in 1997. If you've ever worked helpdesk, ever had a customer say “my cup holder broke” (yes, the CD tray)… or ever felt underestimated in a room full of engineers, this one's for you. Because we throw around some tech terms in the conversation, here are a few friendly definitions so everyone can follow along. Terms We Mentioned (in plain English) QA (Quality Assurance) Think of QA as the people who try to break things on purpose so regular users don't break them accidentally . They test software, hardware, websites — you name it — to catch bugs before they cause chaos. If it's glitch-free, a QA person probably saved the day behind the scenes. Content Moderation This is the work of keeping the internet from turning into the Wild West. Moderators review posts, comments, images, and videos to make sure they follow community rules and don't harm users. It's a mix of tech tools and human judgment — and yes, it can get intense. Building PCs Where many IT careers start! Building PCs is basically grown-up Lego: picking parts assembling them hoping you don't zap anything with static electricity praying the cable management gods smile upon you It's one of the most empowering skills in tech and often the first time someone realizes, “Oh hey… I can actually do this.” Gender Equality & Inequality Gender equality means giving everyone the same chance to succeed — no matter who they are. Gender inequality is what happens when that doesn't happen. In tech, inequality often looks like: being talked over being paid less being assumed “non-technical” having to prove yourself twice as hard being the only woman in a room… again Elsbeth has seen all of this firsthand since 1997 — and she's got stories. End-User The end-user is simply the person who actually uses the product. Not the engineer who built it. Not the manager who approved it. Not the QA who tested it.

There are three main types of nuclear fuel in commercial use today. These are natural uranium, enriched uranium, and mixed oxide or MOX uranium-plutonium mixtures. It is possible to use thorium in a sort of thorium-plutonium or thorium-uranium MOX fuel, but this not currently economically viable at this time when uranium is so cheap and abundant. Spent fuel can be recycled and used in a reactor again. Medical isotopes are an important byproduct of the nuclear industry, and a large share of the world's population has benefited from this at one time or another. 32 Conclusion In the next episode I will describe the basic features and characteristics of reactors together with descriptions of the most widely used commercial reactor types. This concludes the second episode of an 8 part series on nuclear reactor technology. Provide feedback on this episode.

This show has been flagged as Clean by the host. Hello, again. This is Trey. Welcome to part 5 in my Cheap Yellow Display (CYD) Project series. If you are still listening to me ramble about this project, thank you. If you wish to catch up on earlier episodes, you can find them on my HPR profile page https://www.hackerpublicradio.org/correspondents/0394.html To review, My project is to build a portable morse code "Keyer memory" which can be connected to any of my HF transceiver radios by simply plugging it in to the code key input port. Then I could transmit stored messages by simply touching their specific icon on the touch screen. I also want to be able to program each macro individually from the graphical user interface (GUI). To do this, I need to learn how to build a GUI. Most of the CYD resources I have been referencing recommend using Squareline Studio for GUI development on the CYD. Sadly, Squareline Studio is not open source. If any of you have experience with a good, open source alternative to Squareline Studio, please record a show to help the rest of us. Squareline does have a free trial and a free single user / single computer license, which I am using for this project. It will run on Windows, Linux, and Mac. After watching several videos about using the CYD with Squareline, I started to outline the functionality I needed. Squareline provides a wide range of pre-configured boards and interfaces to choose from, in addition to widgets and controls which you can drag onto your screens, and it will automatically generate the supporting code in the background. The initial page needs to have the macro buttons, with labels for the message they will send when pressed. There also needs to be navigation buttons to move from one page to others. Another important page will be the configuration page, where the user can store the contents of each macro and set the speed at which code will be sent. I would like to have a keyboard page where the user can type a custom message and send it. I made a few GUI sketches on post-it-notes, then I installed Squareline Studio on my Ubuntu laptop to start designing. There is a bit of a learning curve. Even with guide videos, I found the user experience to be... challenging. Their own GUI leaves much to be desired. It was not designed to run on the laptop's screen size/resolution. I had to switch to a much higher resolution monitor and rearrange frames within the app itself in order to see many of the controls. Button size adjustments, alignments, and label text did not work quite as expected. Getting things sized and aligned properly took quite a bit of fiddling. The text displayed on a button is a separate object from the button itself, so I have had to put some thought into object naming so that I can write code which will change button labels dynamically. I am including some screenshots from Squareline for the interface I designed. One great feature is that you can define actions and conditions for objects in your project. For example, there are buttons on the left which will navigate to specific screens. I defined actions within Squareline, such that when the specific navigation button is pressed, it will change the button appearance to look like it has been pressed and will then scroll left or right to a specified screen. Actions were also valuable for the Speed (WPM) slider on the Config screen. When this slider is moved left and right, the GUI will change the actual number for WPM to the right of the slider. Next, there is a simulator function which can be used to test how well the GUI works. It took some trial and error, but I was able to build and successfully test, navigational actions and the WPM slider. As I was working on building the afore mentioned WPM slider, and thinking about the default words per minute of Morse to use, my ADHD interrupted me (As usual). I decided to change the default speed that I use for the Arduino Nano based Morse code practice keyer which I keep on my desk. You can learn more about this keyer in episode 3 of this series. And we will also discuss Morse code speed in a future episode in this series. The original code (As found on https://github.com/jmharvey1/ArduinoCPO ) specified 12 words per minute (WPM) as the default speed, with buttons to increase or decrease this. However, I am practicing at 20 WPM. Every time I turn on the practice set, I need to turn up the speed and guess when I am close to 20. I went ahead and opened the PracticeOscilator project in Arduino IDE and updated the wpm variable to a value of 20. No, you will not see this change reflected in my own GitHub repo because: A) I wanted to test it locally first B) 20 WPM may be a little fast for a default C) I do not use git the way that it is meant to be used, or the way I SHOULD be using it, with pull requests and all. Bad Trey. D) I was distracted ANYWAY, the reason I bring this up is that it is the first time I have used the Arduino IDE to program a board with this system since I upgraded from Ubunto 20.04 to Ubuntu 22.04. Try as I might, I was not able to get the Arduino Nano's USB port to be recognized in Linux so that I could upload the updated keyer code. I spent several days troubleshooting, using other Arduino devices, different USB ports, and different cables, all to no avail. If anyone has any recommendations, I am open to suggestions. So, I dug out my son's old Windows 10 PC and started again. I had to install the Arduino IDE, load all the necessary libraries, and my code from Github (Which I had to manually change once again, because I don't fully get git). Finally I was able to update the Arduino Nano with its new code, and it works perfectly. But this revealed the same problem for the CYD. I also could not get it to connect over USB to my Ubuntu system. Time to migrate the entire project to Windows. My next step was to install Squareline Studio on Windows. Here, I ran into another snag, as my trial license was only for one system, so I had to uninstall Squareline from Linux before I could activate the license on Windows. Did I mention that I would love to find an open source, free software product to use instead? If you know of one, please ping me or post a comment. I wasted more time trying to get the GUI project I had written on the Linux machine imported into Squareline on Windows, all the while thinking of improvements I could make if I started again from scratch. It would not load, and would not load. In the end, I started all over again. After much blood sweat and tears, my GUI code was working again, and this time in Windows. I was able to run it in the simulation mode and move from page to page successfully and also use the WPM slider. I exported the UI from Squareline, and I loaded the code it generated into a new project within Arduino IE. Now was the moment of truth. I followed instructions found on the Pang YouTube channel video [ESP32 + LVGL] Configuration input device rotary encoder ( https://www.youtube.com/watch?v=aGM6gu9OpbA ). I connected the CYD and uploaded the code. SUCCESS!! You can see my "Send" screen loaded perfectly! Now to try other screens. Wait. Drat. It does not seem like my navigation buttons work. Actually, it does not appear that the touch screen is responding at all. I spent the next several days trying to figure out what went wrong. I checked and double checked interrupt and configuration settings (Such as those described in another of Pang's videos, [CYD + LVGL] Configuration Cheap Yellow Display | Easy Guide ( https://www.youtube.com/watch?v=qmR-mjJVumU ). Nothing worked. I came to realize that I bit off more than I could chew, and I should NOT have started with such an ambitious project. Instead I should have started with a simple equivalence of "Hello World", where I could build and test simple functionality to make sure I knew exactly what I was doing, then expand on it. Lessons learned, and a good stopping point for this episode. I am open to your feedback on what you would recommend, what I should do differently, etc. You can post simple feedback as a comment or send me an email using the address in my HPR profile. As usual, if your feedback is more than a sentence or two, you might want to record it as an episode so that other listeners can benefit from it as well. Time for an espresso. Maybe I will make it a double. Or even a triple! Provide feedback on this episode.

Goal: send a voice signal on VHF or UHF, receive and record with SDR via RTL dongle Core Problem and Resolution An issue may have been a hardware I/Q Imbalance in the RTL-SDR, which suppressed the desired signal, resulting in very low output volume that required excessive manual amplification. Initial Problem: Very quiet, barely audible recorded audio, initially on UHF 433 MHz Key Discovery: An I/Q imbalance caused a repeating signal "image" in the spectrum, Frequency Change: Switched to the VHF 145.500 Mhz band, Gain Override: To overcome the defect and the failing AGC, gain stages were manually adjusted: Squelch: Squelch (SQL) was set to OFF (0) to prevent the software from muting the quiet, legitimate signal. Adjusted the final Sound Output/Recording Gain on the host OS to match the maximized digital output, achieving audible voice. Summary of Key Radio and Software Settings Transmitting Radio (Baofeng UV-5R): Operation: Simplex (direct radio-to-SDR). Mode: Narrowband FM (NFM).

Setting up Linux Mint with Custom LVM and Luks Linux Mint with Custom LVM on LUKS Overview The current Linux Mint installer doesn't support custom partitions when setting up a new machine with LUKS encryption using LVM. I prefer having a separate partition for my home directory and a backup partition for Timeshift, so that reinstalling or fixing issues won't overwrite my home directory. I found several approaches to achieve this. One method involves setting up partitions first and then using the installer to select them, but this requires extensive post-installation configuration to get boot working with the encrypted drive. I discovered this blog which explains how to repartition your drive after installation. Combined with my guide on setting up hibernation, I created this documentation to help remember how to install a fresh copy of Linux Mint with LVM and LUKS. Tested on: Linux Mint 22 Cinnamon Partition Layout For this guide, I'm working with a 1TB drive that will be split into the following logical volumes: Root - 100GB (system files and applications) Swap - 32GB (for hibernation support) Home - 700GB (user files and documents) Backup - 100GB (Timeshift snapshots) Unallocated - ~68GB (reserved for future expansion) This setup ensures that system snapshots and user data remain separate, making system recovery much easier. Installation Guide Step 1: Initial Linux Mint Installation Start the Linux Mint installation process as normal: Boot from your Linux Mint installation media Follow the installation wizard (language, keyboard layout, etc.) When you reach the Installation type screen: Select "Erase disk and install Linux Mint" Click "Advanced features" Enable both options: ✓ Use LVM with the new Linux Mint installation ✓ Encrypt the new Linux Mint installation for security Click Continue Enter a strong encryption password when prompted Complete the rest of the installation (timezone, user account, etc.) When installation finishes, do NOT click "Restart Now" - we'll repartition first Important: Do NOT reboot after installation completes. We need to repartition before the first boot. Step 2: Access Root Terminal After installation finishes, open a terminal and switch to root: sudo -i This gives you administrative privileges needed for disk operations. Step 3: Check Current Disk Layout View your current partition structure: lsblk -f This displays your filesystem layout. You should see your encrypted volume group (typically vgmint) with a large root partition consuming most of the space. Step 4: Resize Root Partition Shrink the root partition from its default size (nearly full disk) to 100GB: lvresize -L 100G --resizefs vgmint/root What this does: -L 100G sets the logical volume size to exactly 100GB --resizefs automatically resizes the filesystem to match This frees up ~900GB for our other partitions Step 5: Resize Swap Partition The default swap is usually small (a few GB). We need to increase it to 32GB for hibernation: lvresize --verbose -L +32G /dev/mapper/vgmint-swap_1 What this does: -L +32G adds 32GB to the current swap size --verbose shows detailed progress information This ensures enough swap space for RAM contents during hibernation Note: For hibernation to work, swap should be at least equal to your RAM size. Adjust accordingly. Step 6: Create Home Partition Create a new logical volume for your home directory: lvcreate -L 700G vgmint -n home What this does: -L 700G creates a 700GB logical volume vgmint is the volume group name -n home names the new volume "home" Step 7: Create Backup Partition Create a logical volume for Timeshift backups: lvcreate -L 100G vgmint -n backup What this does: Creates a dedicated 100GB space for system snapshots Keeps backups separate from user data Prevents backups from filling up your home partition Step 8: Format New Partitions Format both new partitions with the ext4 filesystem: mkfs.ext4 /dev/vgmint/backup mkfs.ext4 /dev/vgmint/home What this does: Creates ext4 filesystems on both logical volumes ext4 is the standard Linux filesystem with good performance and reliability Step 9: Mount Partitions Create mount points and mount your partitions: mkdir /mnt/{root,home} mount /dev/vgmint/root /mnt/root/ mount /dev/vgmint/home /mnt/home/ What this does: Creates temporary directories to access the filesystems Mounts root and home so we can configure them Step 10: Move Home Directory Contents Move the existing home directory contents from the root partition to the new home partition: mv /mnt/root/home/* /mnt/home/ What this does: Transfers all user files and directories from the old location to the new home partition Preserves your user account settings and any files created during installation Without this step, your home directory would be empty on first boot Step 11: Update fstab Add the home partition to the system's fstab file so it mounts automatically at boot: echo "/dev/mapper/vgmint-home /home ext4 defaults 0 2" >> /mnt/root/etc/fstab What this does: Appends a mount entry to /etc/fstab Ensures /home partition mounts automatically at startup The 0 2 values enable filesystem checks during boot Step 12: Clean Up and Prepare for Reboot Unmount the partitions and deactivate the volume group: umount /mnt/root umount /mnt/home swapoff -a lvchange -an vgmint What this does: Safely unmounts all mounted filesystems Turns off swap Deactivates the volume group to prevent conflicts Ensures everything is properly closed before reboot Step 13: Reboot Now you can safely reboot into your new system: reboot Enter your LUKS encryption password at boot, then log in normally. Verification After rebooting, verify your partition setup: lsblk -f df -h You should see: Root (/) mounted with ~100GB Home (/home) mounted with ~700GB Swap available with 32GB Backup partition ready for Timeshift configuration Setting Up Timeshift To complete your backup solution: Install Timeshift (if not already installed): sudo apt install timeshift Launch Timeshift and select RSYNC mode Choose the backup partition as your snapshot location Configure your backup schedule (daily, weekly, monthly) Create your first snapshot Additional Resources Original blog post on LVM rearrangement Setting up hibernation on Linux Mint Conclusion This setup gives you the best of both worlds: the security of full-disk encryption with LUKS, and the flexibility of custom LVM partitions. Your home directory and system backups are now isolated, making system recovery and upgrades much safer and more manageable. Automating Your Linux Mint Setup After a Fresh Install Automating Your Linux Mint Setup After a Fresh Install Setting up a fresh Linux Mint installation can be time-consuming, especially when you want to replicate your perfect development environment. This guide will show you how to automate the entire process using Ansible and configuration backups, so you can go from a fresh install to a fully configured system in minutes. Why Automate Your Setup? Whether you're setting up a new machine, recovering from a system failure, or just want to maintain consistency across multiple computers, automation offers several key benefits: Time Savings: What normally takes hours can be done in minutes Consistency: Identical setup across all your machines Documentation: Your setup becomes self-documenting Recovery: Quick recovery from system failures Reproducibility: Never forget to install that one crucial tool again Discovering Your Installed Applications Before creating your automation setup, you need to identify which applications you've manually installed since the initial OS installation.

In this episode, Lee sits down with Elsbeth Starling — fae-coded creator, mesh-maker, scripter, and accidental caffeine-fueled entrepreneur — to talk about what it really takes to get accepted into Second Life's legendary Shop & Hop as a relatively new business owner. At just about a year and a half into her SL journey, Elsbeth breaks down the whole process: how she applied, what the organizers look for, and why imposter syndrome is basically the unofficial application form. Link to the last Shop and Hop information She shares her behind-the-scenes workflow using GIMP , Blender , and LSL scripting to turn simple mesh ideas into fully interactive creations. (Spoiler: it involves equal parts stubbornness and fairy dust.) We dive into SLRead , the virtual HUD-based e-reader system she and Lee created — a tool that brings the joy of real-life reading into the digital world, complete with pages, collections, and a whole lot of cozy vibes. Elsbeth also reveals her newest item premiering at Shop & Hop: an interactive story-time décor piece that lets ANY avatar sit down, pick one of six sweet stories, and be read to in local chat. Think “campfire storytelling,” but with lag and better fashion. We wrap up by talking through the practicals: the cost of participating, how sales work at large SL events, the realities of being a smaller creator in a massive marketplace, and why Shop & Hop can be one of the best visibility boosts for emerging designers. If you're an SL creator dreaming of Shop & Hop — or just curious how creators bring magic into the metaverse — this episode is a must-listen. Provide feedback on this episode.

This show has been flagged as Clean by the host. Hello, again. This is Trey. Welcome to part 4 in my Cheap Yellow Display (CYD) Project series. If you have hung in there with me so far on this journey, thank you. If you have missed earlier episodes, you can find them on my HPR profile page https://www.hackerpublicradio.org/correspondents/0394.html If you have questions, comments, concerns, or other feedback, please leave an episode comment, or drop me an email (Using the address in my profile). Even better, you could record and upload your own show which shares your viewpoint or expertise. To review, I finally have an actual project to build using the CYD. It is a portable, programmable morse code "Keyer memory" which can be connected to any of my HF transceiver radios by simply plugging it in to the code key input port. Then I could transmit stored messages by simply touching their specific icon on the touch screen. So, now I purchased a pair of CYDs. Each arrived in an anti-static zipper bag with a USB C cable, a 6 inch long 4 pin PB1.25mm to Dupont 2.54mm cable harness, a plastic case holding the CYD itself and a small plastic stylus. There are pictures in the show notes. Depending on how many IO connections I may need, and how I plan to power this, I am probably going to need more 4 pin PB1.25mm wired connectors. You can see a description of the various features and connectors on RandomNerdTutorials writeup about this board ( https://randomnerdtutorials.com/cheap-yellow-display-esp32-2432s028r/ ). The only difference I can see between this description and what I received is that mine have both a MicroUSB and USB C port. Of course, first thing, I had to plug it in and see what happens. It appears to be running some kind of simulation of a web site. The backlit display looks alright. It is not super high resolution, but for the price, it will suite my needs. The touch screen is responsive, but it is pressure sensitive and works best using the provided stylus or a fingernail and not your finger tip. So, I have the CYD. What other hardware do I need? I need to address how one of these will actually connect to my radios. Modern amateur radio transceivers which support continuous wave (CW) transmission (Which is another name for Morse code) generally can use one of two different pieces of hardware for input. The first is what we call a straight key. Below is a photo of the one I own. This is a classic, old fashioned telegraph style code key. It is designed to quickly and easily be pressed down to close a circuit and when released the circuit is opened, effectively making it a normally open push button switch. To send a dot, the operator holds down the key for a short period of time, then releases it. To send a dash, the operator holds down the key for a longer period of time, before releasing it. (We will discuss actual timing specifications for morse code in a future podcast) Connectivity for the switch has been standardized to use a 3.5 mm mono male phone connector which has only sleeve and tip connections. The second option is a paddle style electronic keyer. There are many styles of these, and I am including a picture of the one I use, which once belonged to a close friend of mine who is now silent key. In general, the paddle is two separate normally open switches. In the most common configuration, if an operator presses and releases the paddle on the right, a dash is sent. If the paddle on the right is held, a continuous series of dashes will be sent until that paddle is released. The left paddle works similarly. If it is pressed and released, a single dot is sent. If it is pressed and held, a series of dots is sent until it is released. The function of these paddles can be swapped from left to right using the radio configuration. There is additional functionality which can be configured in some radios for when both paddles are pressed simultaneously, but I am not going to describe those here. The paddle generally uses a 3.5mm stereo male phone connector with the sleeve being common. The tip of the phone connector is wired to the left paddle and ring of the connector is wired to the right paddle. Most modern radios have a built in keyer which can be configured for a paddle and will automatically transmit the dots or dashes at whichever speed is configured based on the paddle pressed. You can see this phone connector illustrated on Wikipedia's phone connector page. . https://en.m.wikipedia.org/wiki/Phone_connector_(audio ) You can learn more about all the various devices which can be used for sending morse and how they function at Morse Code World . https://morsecode.world/keys.html Ideally, controlling all the morse code timing within the CYD would be best. That way, it could be connected as a straight key and any keyer settings already configured within the radio shouldn't matter. However, If I wish to also be able to manually send morse code myself using my paddles, without disconnecting the CYD and reconfiguring the radio, that could be problematic. I may need to factor in the possibility of connecting my paddle to the CYD and then building in code to respond to inputs from the paddles. As I mentioned in a previous episode, I have an Arduino Nano on my desk as a practice oscillator for my paddles. I may be able to reuse some of that code on the CYD. So, if I want the CYD to appear to the radio like a straight key, I will need it to be able to control a switch quickly and accurately. But I also want the CYD and the radio to be electrically isolated from each other. This calls for a relay. I was able to find and order some inexpensive relay modules which work nicely with Arduino and ESP32. These allow connectivity to 5v power and to one of the CYD's GPIO pins. These feed an optocoupler circuit, which, in-turn, drives the coil of the relay. This provides inductive kickback protection to the CYD and can drive a coil which would require more current than the GPIO can provide. Inductive kickback rabbit trail: An inductor is simply a coil of wire. Direct current flowing through any wire generates a magnetic field. Within the inductor, because the wire is coiled, the magnetic field builds from each pass of the wire in the coil. If you include an iron core, it sustains the magnetic field even better. This is the basis for an electro magnet. A relay is simply a momentary contact switch controlled by an electromagnet. One unique property of an inductor is that, current wants to keep flowing in the direction it was applied. To be specific, when the current source is removed, the magnetic field still exists for a while, and it effectively "generates" an electric current within the coil, in the same direction as the one which initially created the magnetic field to begin with. If it has a path to flow, this current will create another weaker magnetic field, which creates its own electric current, in a diminishing loop. If the circuit which drives the coil of a direct current relay is not ready for this continued push of current, damage can be done. Many times this is countered by wiring a "flyback diode" in parallel with the coil and in the opposite direction in which current will be applied. This way, when the current source is stopped, the diode gives a path for the inductive kickback current to safely flow while the magnetic field dissipates. Explained in greater detail at https://inductive-kickback.com/2019/04/inductive-kickback-made-simple-to-grasp-easy-to-handle/ The switch side of the relay is a single pole double throw (SPDT) and makes connections available for common, normally closed (NC), and normally open (NO). It will be easy to connect the common and NO connections to a 3.5mm mono male connector so that it may be plugged into the "key" port on any radio transmitter. I will need to do some testing on the speed of the relay, but I think it will work just fine. Once I start writing some code for the CYD, I will be able to connect and test the relay. Well, this is a good place to end this episode, and it is one of the longest in this series so far. In the next episode, we will begin to look at how we design the user interface for our program, something I do not know anything about (yet). Stay tuned weekdays for additional exciting episodes of Hacker Public Radio, and, at some point, the next episode in this series.

It is a data base from where documents can be downloaded as pdf-files. As a visitor I can login to the archive as a guest. When I find a document of interest after search I can right click on the pdf icon and download the document. But I can not. No download when I click on the pdf icon. This is the first time I visit this archive so I do not know exactly how it works. It was time to investigate the root cause. I use Firefox on a Linux machine. I tested several methods to see if any would solve the issue. I tried by changing settings for pop-ups. I changed Firefox security settings. I disabled VPN. I disabled Firefox extensions for blocking trackers. I tested also the Chromium browser as well as the Epiphany browser. All those methods resulted in no difference; nothing happened. I was in contact to a friend on Windows and also staff at the Archive, both telling me that from Windows it worked, including with Firefox. So now I knew the archive works and that it works on Firefox. So I thought, can this somehow be related to Linux? I asked in a Linux forum if someone on Linux could test to download. One person in the forum tested and solved the problem. I would not define it as a Linux problem, but a site design that affected Linux users. The trouble was something I had not thought of: The User Agent. When my browser contact a web site, my browser can tell the site what kind of browser I use, which operating system I use and more. This information can be used by the site to optimize the presentation of the content for me. For to me unknown reason, maybe a mistake, maybe related to some old design compatibility issue, this site did not accept the information my user agent provided. The solution is to tell the web site I am something else. In the browser has Developer tools. When opening the developer tools from meny, typically a developer window with tools and analytics is opened at the bottom part of the web page. One tool is network. Within network I can simulate how the site looks on different devices, with different network connections and also with different User Agents. The tools are similar in both Firefox and Chromium. The exact list of standard options differ and Chromium has more options preloaded. In this specific case, when I in Developer tools on Firefox change User Agent to Chrome Desktop, which relates to Chrome on Windows as I understand, and then reload the web page I can now download the pdf file from the archive. When this web site interpret me to be this other type of user, they can understand each other without any issue. I have reported back to the site owner and hopefully this specific site will not need this work around for the browser User Agent in the future.Provide feedback on this episode.

This topic was brought to my attention when I came across this video from The Hated One . This youtube host is extremely privacy focused, and has interesting opinions on not only US privacy and security topics, but also internationally. This particular video was regarding locking down the settings on Firefox. The claim besides increasing security is to lower bandwidth and memory usage and double rendering speeds. While a lot of these steps the author took seemed excessive, they might help you. I use a few of these settings as a takeaway to this video, as well as an extension that I find very useful. The author is correct in saying that our browsing habits track a lot about your personal life, so here are a few steps that I did follow. First, I selected Strict Blocking under Content Blocking about:preferences#privacy Strict blocking Firefox setting Next, I did not set my history settings to Use custom settings for History and Always use private browsing mode , this is maybe useful for some. Under Address Bar I left everything unchecked, besides Search Engines Firefox address bar settings Next, check the box in Ublock origin settings enable Advance User settings to enable more granular control. Ublock Origin settings Ublock Origin granular control Now, change the default behavior of Ublock origin to Block media elements Block remote fonts Disable JavaScript By checking the boxes for these items Transcript: How to configure Firefox settings for maximum privacy and security Provide feedback on this episode.

This show has been flagged as Clean by the host. A Deeper Look Triggers & Conditions: The blueprint uses both a state change from not_home to home for your PC tracker and a motion sensor activation. A numeric state condition ensures that the automation only runs when ambient lighting (from your illuminance sensor) is below the defined threshold (default 37 lux). This minimizes unnecessary operations when the area is already well lit. Light Brightness Based on Sun: Using the built-in sun condition, the automation distinguishes between a day period (starting 30 minutes after sunrise) and a night period (adjusted using offset around sunset). This means your light's brightness is automatically tailored to the natural light context, setting it to the day brightness (default 81%) or to the night brightness (default 69%). Handling PC Presence & Motion: Two branches further refine the control: If the PC is not_home, the blueprint waits until motion ceases before turning off the light. If the PC is home and ambient light remains low, the light is ensured to remain on until the PC changes to not_home, at which point the light turns off with a smooth transition and a flash effect. This design is ideal for scenarios where a PC's presence and environmental conditions are combined to manage indoor illumination dynamically.

UCSD p-System is an operating system from the late 1970s which carried on into the 1980s. It ran on a variety of different micro and mini computers. The notable thing about it is that it ran programs on a portable virtual machine rather than directly on the native hardware. This podcast episode overview will give a very brief overview of the operating system, its features, and its history. This episode is for people who are interested in some of the more obscure history of the early microcomputer era. Don't expect to find something here that you can put to use in a practical way. 02 Pascal and UCSD 03 Commercialization 04 UCSD p-System Versions 05 Hosted Versions 06 Basic Concepts 07 File System 08 Virtual Memory and Multitasking 09 Architecture Independence with P-Code 10 Programming languages 11 The Fading Away of the p-System and its Demise 12 A Quick Tour of the p-System - Running it on Modern Hardware 13 A Quick Tour of the p-System - the User Interface 14 A Quick Tour of the p-System - OS Level Menu 15 A Quick Tour of the p-System - ASE Editor 16 A Quick Tour of the p-System - Filer 17 A Quick Tour of the p-System - Xecute 18 A Quick Tour of the p-System - DOS Filer 19 Conclusion The UCSD p-System is an example of an operating system from the early days of microcomputers that did not follow the conventions that we are used to today. It had features that were in many ways ahead of its time. Here are some examples of this. It was almost entirely written in a high level language, Pascal. Programs compiled to p-code (or Pascal code) that ran on an architecture indepedent virtual machine. Performance critical parts of the p-code could be compiled to native code. The user interface did not use a command line, indeed there was none. Instead it used a menu driven user interface. On the other hand it remained stuck on 8 bit limitations in a 16 bit world. It was closed source proprietary product, and when the vendor lost interest, the product died. It's an interesting bit of history, but I can't really recommend that anyone should expect to do anything useful with it today. I still have a copy that I bought when it was a current product, but it has been many years since I even looked at it, and I only resusitated it for the sake of making an HPR episode. 20 Adendum - Performance Benchmarks Provide feedback on this episode.

You need to know which OATH options the site you wish to log into uses in order to use OATH. 07 Options - TOTP versus HOTP There are two different types of OATH one time passwords, HOTP and TOTP. HOTP uses a counter. I won't go into more detail on HOTP as I haven't come across anyone using it. TOTP uses the current time instead of a counter. The time is fed into the OATH algorithm along with the shared secret to generate a new password on both ends of the connection. All the instances of OATH that I am familiar with use TOTP. 08 TOTP Mode Totp has different "modes". These modes are hash encoding algorithms such as SHA1, SHA256, or SHA512. The correct mode must be selected in order to log in using OATH with TOTP. 09 Encoding - Hex versus Base32 Both ends of the connection must be initialized with a shared secret or key which is required as part of the OATH algorithm. This key could be encoded in one of two forms, either hexadecimal or base32. Web sites often do not document which encoding method they are using. If you cannot determine the encoding of the key by simply looking at it you may need to use trial and error during your first OATH log in attempts to see which type of key has been used. 10 Github and Pypi Options Github and Pypi are two of the most prominent web sites using OATH. Both use the same options, TOTP with SHA1 mode, and base32 encoding. 11 Using Oathtool oathtool is a simple command line application which generates one time passwords for use with OATH. It can be run in a terminal. However, can also be turned into a simple GUI application using Zenity. Will discuss this in more detail later. By default oathtool uses hotp and hex encoding. To use totp and base32 encoding you must specify these on the command line. To specify base32 encoding for use with for example Github, pass the "-b" or "--base32" argument on the command line. To specify TOTP, pass the "--totp" argument on the command line. By default, oathtool uses SHA1 with totp, so you don't need to specify that if you require SHA1. If you need a different TOTP mode, you specify that as part of the TOTP argument separated by an "=" character. For example "--totp=SHA256". 12 Oathtool Example Here is a simple example of using oathtool to create a one time password to use with Github or Pypi. Open a terminal and type the following. oathtool -b --totp SOMEBIGBASE32SECRETCODE The one time password will be printed out in the terminal. You can try this out without using a valid key so long as it is a valid base32 string. When used with a valid key you then enter that one time password into Github, Pypi, or other web site where it asks for the one time password. Note that I have not covered in the above how to store and retrieve the key securely, as that is too big of a topic to cover here. 13 Zenity Example Oathtool is a command line application, but if you are using Linux it is simple to convert it into a GUI application by using "Zenity". Zenity is a simple to use package that creates GUI windows on the command line or in a shell script. There are two steps to the proceess. First create the OTP from the key by using oathtool and save it in a variable. Next, call a Zenity "info" window with the OTP as part of the provided text. You can now copy and paste the OTP from the window into your web browser. To close the window, click on the "OK" button. See the previous note on storing the key securely. hprcode=$(oathtool -b --totp SOMEBIGBASE32SECRETCODE) zenity --info --width=150 --title="HPR 2FA" --text="2FA code is: nn $hprcode n" If you are using Gnome you can make the script launchable from the desktop by creading a ".desktop" file in the "Desktop" directory.

You can find Part 1 in episode 4472 and Part 2 in episode 4488. We previously left our handy hero searching for a solution to an amateur radio signal propagation dilemma, while he is trying to become proficient with Morse code. The CYD technology is simmering in the back of his brain – an answer in search of a problem. Hah! I love trying to create the feel of a vintage radio or television series with the intro and outro for these episodes. But I am by no means the hero. I am simply Trey – a grumpy old man and tinkerer. Instead, the real hero in this episode is Keith VE3SVQ-THE SHAKY KEY on YouTube. So.... Let's see. Where were we? Oh yes. I have been trying to learn Morse code -.-. --.- -.-. --.- (CQ CQ) That was me, tapping out "CQ CQ" in Morse code using the practice set I keep on my desk. This consists of a set of code paddles, connected to an Arduino Nano, which I built several years ago based what I learned watching Code Practice Oscillator; Aka: The Three Arduinos on Jmhrvy1947's YouTube Channel, and based on the code from his GitHub https://github.com/jmharvey1/ArduinoCPO . I did need to make modifications, both to support the Ardunio Nano on which I chose to run it, and for my own sanity, as the way that I learned to write code for Ardunio is very different. I focus on readability and flexibility. You can see these changes on my own GitHub ( https://github.com/jttrey3/PracticeOscillator/blob/main/PracticeOscillator.ino ) Anyway, I have been studying. I have been watching videos. I have been practicing. I might actually be learning some of this stuff. If you are interested in more details about the resources I am using, leave a comment for this episode, or drop me an email using the address in my profile, and I may record an episode about it. The result is that I have been learning. But also, the google and YouTube algorithms have been learning about me. And they have started to feed me more videos about Morse code. It is both helpful, and super creepy at the same time. So one day, when I opened YouTube, a title in my feed caught my eye. " NEW CW OP USE THE REVERSE BEACON NETWORK TO IMPROVE YOUR CODE ". I said to myself, "Self, this could be interesting." I watched Keith's video and learned about the Reverse Beacon Network . According to their website, "The Reverse Beacon Network (RBN) is a revolutionary new idea. Instead of beacons actively transmitting signals, the RBN is a network of stations listening to the bands and reporting what stations they hear, when and how well." Let's pause for a second and discuss amateur radio beacons. These are stations which repeatedly broadcast their identity on dedicated frequencies. Other operators around the world, who hear a beacon, can evaluate the signal propagation between their station and the beacon location. The RBN is just the opposite. Here, the station operator can transmit a test signal with their call sign, using CW or other digital modes. Then, they can look at the RBN website to see which RBN listening stations received their transmission, and even get a signal report. On the main page of the RBN website, one can observe a world map with paths showing where signals were received, and where they originated based on the registered grid square of the originating call sign. The table displayed below the map reveals the sending and receiving call signs, their distance apart (In miles or kilometers), the frequency, the mode, the type of transmission, the signal to noise ratio, the speed of the transmission, and the time/date using UTC. This information is collected by a network of volunteer reverse beacon receiving stations all over the world, which monitor the various radio bands, decode transmissions of CW (Morse code), RTTY (Radio Teletype), and PSK31 or PSK63 (Digital modes using Phase Shift Keying). These receiving stations report what they receive as well as the signal strength back into the Reverse Beacon Network to be recorded and published over the internet. Dave Casler discussed the RBN back in 2016 on his YouTube video The Ham Radio Reverse Beacon Network, AD#32 . This gives very good detail of how the network works. This sounds like exactly what I have been looking for. All I need to do is come up with a way to reliably, accurately, and consistently transmit "CQ CQ CQ TEST DE" followed by my call sign three times at a constant 20 words per minute (WPM). If I can do this a few times, I can then check the RBN to see where I was received. By including the "TEST" string, recipients know that I do not wish to start a conversation. I can get accurate reporting of where my signal is going and how strong it is. But remember that my morse code skills are still inadequate. And my radios do not have "Keyer memories" like those which can be found in higher end transceivers like the Icom 7300, enabling programmed messages to be sent at the touch of a button. But there is a fairly inexpensive solution to this problem. One which has been nagging at the back of my mind. Maybe, I could use the Cheap Yellow Display to effectively add "Keyer memory" to any of my radios by simply plugging it in to the code key input port. These stored messages could be transmitted by simply touching their specific icon on the touch screen. Now we have a plan. But how will we do it? What else will we need to learn? Will it even work?
