This show has been flagged as Clean by the host. Lessons I've learned moderating 5+ tech panels: Preparation: Be familiar with the panelists and their subject matter. Avoid asking common questions. Set up the stage using a semicircle arrangement rather than formal tables to promote dialogue between panelists. Ensure that each panelist has their own microphone to prevent any accidental dominance in the discussion. Execution: Set a friendly and informal tone before the panel starts to help nervous panelists relax. Involve the audience by encouraging questions and conducting polls to increase engagement. Use a central microphone for audience questions to avoid delays and maintain a smooth flow. Listen carefully to questions and rephrase them if necessary to ensure clarity for the panelists. Know when to politely wrap up discussions to keep the conversation moving. Provide feedback on this episode .…

This show has been flagged as Clean by the host. Hi all! Topics Topic 1: Hello, my name is Antoine. Topic 2: I listened to you! a) Comment from Archer72: "[...] Audio setups are *definitely* of interest to hackers :)" Link: https://hackerpublicradio.org/eps/hpr4325/index.html#comment_4278 b) From hpr4351 :: HPR Community News for March 2025 (on the show) Something like: 'I'm not going to read your (long) comments, give a show on it'. Sorry for making you read my comments, dear HPR Janitors! (Specially you, good-voice Sgoti) Link: https://hackerpublicradio.org/eps/hpr4351/index.html Topic 3: My audio setup (Also you can see written on a commentary of mine on the link on Topic 2 a). Topic 4: My audio editing (when I do) With examples. * On the sibilance ("sss") example, the adjustment settings for the to-be-better fragment was an agressive cut of -7.4 dB on frequency 5.8 kHz (for advanced curiosity: Q 4.73, threshold -36.3 dB, ratio 3.8:1). Did it only with some testing, and knowing that sibilance normally is at about 6 kHz (when it happens, because here the dynamic microphone ended up not capturing too much of it). Topic 5: I'm in a new working time If you can, do a word of prayer to God in favour of me. If anything I said "that is better" is, actually, worse, don't worry thinking you are perceiving it wrongly, it's just that I'm not a professional and can have made it wrong. Or it's only a matter of taste, it's fine also; the ideas are there, and I welcome your participation too. Thank you!

This is just an introduction, here is the rough text of the audio: Hello HPR: I'm murph, I've been an HPR listener for a long-time, into the TWAT days. I'll try to keep it quick. I started in computers in the early 80's with a VIC-20. After a few of the Commodore 8-bits, I settled into the Amiga line, which I daily drove up into this century, and stll have a few. In college in the 90's, I had a dilemma. I wanted to do C programming homework from home, but the expensive Amiga compiler wasn't compatible with the Sun workstations at school. Another student introduced me to Linux, and I promptly ordered a set of Slackware CDs and figured out how to install. I was looking for the compilers to complete my studies, but have stayed for the freedom, and the communities, like this one. I've used countless distros over the years, and use a few for different needs. I am still a Linux user, and system administrator. I've given a few talks on things like gnu/screen, mastodon, tmux ay conventions like Penguicon, SCaLE, HOPE and some more regional conferences. I was inspired by Lyle and Thaj Sera's HPR birds of a feather talk, and thought that it would make a good presentation, and asked them to let me base a talk off of it, which they encouraged. Part of that is how to submit a show, which resulted in me finally, after all this time, finally submitting one of my own, as opposed to the occassional show I've crassly barged into. If you want to reach me, the best ways would be by email or on the fediverse, @murph@hackers.town Thanks for listening.…

Intro Hello, this is your host, Archer72, for Hacker Public Radio. In this episode, this is my third show involving my record player. I am using a Zoom H1essential Stereo Handy Recorder microphone, recording into Audacity for this show. Why visit the record shop? Picking up a record at the record shop expands my music choices. I get a chance to talk to the owner on the weekend when searching for new music. He is an archaeologist and a teacher at a local college during the week, and is knowledgeable on all the music in the store. One Year With the Institute - Archive.org I wanted a way to listen to the records while on my laptop, preferably with headphones, as to not disturb the household. How is this accomplished? This is done using a combination of Darkice to capture the stream, and Icecast to stream it to the local network. What is Icecast? Icecast is a streaming media (audio/video) server which currently supports Ogg (Vorbis and Theora), Opus, WebM and MP3 streams. It can be used to create an Internet radio station or a privately running jukebox and many things in between. It is very versatile in that new formats can be added relatively easily and supports open standards for communication and interaction. Icecast is distributed under the GNU GPL, version 2. The default config file is located in /usr/share/doc/icecast2/icecast.xml.dist.gz icecast.xml.dist if the default config gets mangled or corrupted by myself. Several other types of configs are also in /usr/share/doc/icecast2/ that include a bare bones config and the installed icecast2 config is located in /etc/icecast2/icecast.xml Configuration needed to be personalized <location>Cynthiana,KY</location> <admin>ricemark20.nospam@nospam.gmail.com</admin> Change the passwords from hackme to a more secure password <authentication> <!-- Sources log in with username 'source' --> <source-password>hackme</source-password> <!-- Relays log in with username 'relay' --> <relay-password>hackme</relay-password> <!-- Admin logs in with the username given below --> <admin-user>admin</admin-user> <admin-password>hackme</admin-password> </authentication> <!-- In my case, this is the IP address of the Raspberry Pi --> <hostname>192.168.x.x</hostname> mountPoint = live # mount point of this stream on the IceCast2 server name = DarkIce Vinyl Stream # name of the stream description = This is my Vinyl stream # description of the stream url = http://localhost # URL related to the stream genre = Podca…

If you you take a lot of photos, some of them will show problems. But you don't need to throw them away. With GIMP, you can fix these common problems and restore your photos. In this episode I take a look at two problems that turn out to be related and to have similar fixes: Dark photos, and Color problems.

Background It all happened when I noticed that a disk space monitor sitting in the top right hand side on my Gnome desktop was red. On inspection I discovered that my root filesystem was 87% full. The root partition was only 37GB in size which meant there was less than 4GB of space left. When I thought back I remembered that my PC was running a bit slower than usual and that that the lack of space in the root partition could have been to blame. I had some tasks that I wanted to complete and thought I’d better do something about the lack of space before it became an even bigger problem. What happened As per usual all this happened when I was short of time and I was in a bit of a hurry. Lesson one don’t do this sort of thing when your in a bit of a hurry. Because I was in a hurry I didn’t spend time doing a complete backup. Lesson two do a backup. My plan was to get some space back by shrinking my home partition leaving some empty space to allow me to increase the size of my root partition. For speed and ease I decided to use Gparted as I have used this many times in the past. Wikipedia article about Gparted Official Gparted webpage It’s not a good idea to try and resize and or move a mounted filesystem so a bootable live version of Gparted would be a good idea. The reason for this is that if you run Gparted from your normal Linux OS and the OS decides to write something to the disk while Gparted is also trying to write or move things on the disk then as you could imagine very bad things could and probably would happen. I knew I had an old bootable live CDROM with Gparted on it as I had used this many times in the past though not for a few years. As I was short on time I thought this would be the quickest way to get the job done. I booted up the live CD and setup the various operations such as shrinking the home partitions, moving it to the right to leave space for the root partition then finally increasing the size of the almost full root partition. What I didn’t notice at the time is that there was a tiny explanation mark on at least one of the partitions. I probably missed this because I was in a hurry. Lesson three don’t rush things and be on the lookout for any error messages. When I clicked the green tick button to carry out the operations it briefly seemed to start and almost instantly stopped saying that there were errors and that the operation was unsuccessful and something about unsupported 64 bit filesystems. At this point I thought / hoped that nothing had actually happened. My guess was that the old live Gparted distribution I was using didn’t support Ext4 though I could be completely wrong on this. Lesson four don’t use old versions of Gparted particularly when performing operations on modern filesystems. Wikipedia article about the Ext4 filesystem I removed the Gparted bootable CD and rebooted my PC. At this point I got lots of errors scrolling up the screen I then got a message I’ve never see before from memory I think it said Journaling It then said something about pass 1 pass 2 pass 3 and continued all the way to 5. Then it talked about recovering data blocks. At this point I got very nervous. I had all sorts of fears going through my head. I imagined I may have lost all the contents of my hard-rive. The whole experience was very scary. I let it complete all operations an…
I’m glad I’m here with you! I'll tell my impressions on things of my Brazilian country. Pardon me for some high-volume transitions ! Trying and testing the brickabrackis ( possibilities ). Pleasing or not. Thanks! Topics: 1- Sistema Único de Saúde (the national health system) Works! Any citizen, any person, has access to health treatment: no payment, no check if the person has payed taxes on anything, if is a worker or not. Of course, waiting time might be a problem if it's not an urgency or emergency, and quality varies (as any service, paid or not), according to city (capital or country town, more structured or smaller cities), hospital, the specific doctor and support team etc. 2- Tap water The water from the tap is safe, recognized as drinking water (in my city, and maybe in many if not most). The water treatment company ("Sanepar") here even sells their water bottled, and sponsors events that distribute them (sports events) to show the quality. But people don't use to drink from the tap it directly. If they do not use a filter, it's common to buy water in 20 liters carboys (big plastic bottles, 20L is a bit more than 5 gallons) . I use this last option, but drink water under the shower also. Most people (that I know, of course) simply don't drink water ! I don't know. I don't understand how it is, but they don't drink water, not even a liter per day. Coffee and soda are the most common "substitutes". 3- Religion numbers Statistics about religion are very misleading. You can find different numbers but it's generally: more than half identifying as Catholics. More than 20% evangelical, 10% without religion. But those numbers say nothing about reality of what you find in the streets. Maybe because in some areas it's embarassing to identify as an atheist, as if you're immoral and cannot be trusted; so, people without religion simply say the religion of the family, or the generic "catholic, non-practicing". 4- Brazilian Law Our law is written and detailed. Everything you could want to know about our judicial system, our rights and etc. are explicit in laws; and our Constitution, in force since 1988, with more than 200 articles, guides all. The Supreme Court can make and change interpretations and, thus, issue binding decisions that are not seem in the law, but this is the exception. Cover of the official edition of the Brazilian Constitution in the English Language. (Source: https://www.stf.jus.br/arquivo/cms/legislacaoConstituicao/anexo/Brazil_Federal_Constitution_EC_125.pdf. Accessed on February 2025.) Most of the norms are federal and encompass the entire nation: it is a reason we are so "equal", in many senses, while living in a country with 212 million people (official estimation of IBGE, July 1st 2024 * ) and that represents 48% of the size of South America. 5- Now something very specific to my city, a capital city on the south of the country It's not expected to say Good morning when you cross with a stranger on the street. No Hello or Good morning to the bus driver also. I mean, a lot of people greet, but many don't and it's common to not do so. In many other parts of the country, of course, it's different. For example, I lived in a capital city on the north, and everybody expected you to say Good Morning! when entering an elevator in the morning, behavior that generally makes people think you're strange here in my southern city. If I ask for the name of a seller on a store, to be more polite saying his or her name occasionally if I am making a lot of questions and demanding more attention time, they as…

First, I create a Git repository some place on the server. This is the Git repo that's going to be populated with your content, but it doesn't have to be in a world-viewable location on your server. Instead, you can place this anywhere, and then use a Git hook or a cronjob to copy files from it to a world-viewable directory. I don't cover that here. I refer to this location as the staging directory. Next, create a bare repository on your server. In its hooks directory, create a shell script called post-receive: #!/usr/bin/bash # while read oldrev newrev refname do BR=`git rev-parse --symbolic --abbrev-ref $refname` if [ "$BR" == "master" ]; then WEB_DIR="/my/staging/dir" export GIT_DIR="$WEB_DIR/.git" pushd $WEB_DIR > /dev/null git pull popd > /dev/null fi done Now when you push to your bare repository, you are triggering the post-receive script to run, which in turn triggers a git pull in your staging directory. Once your staging directory contains the content you want to distribute, you can copy them to live directories, or you could make your staging directory live (remember to exclude the .git directory though), or whatever you want. For gopher, I create a file listing by date using a shell script: #!/usr/bin/bash SED=/usr/bin/sed DIR_BASE=/my/live/dir DIR_LIVE=blog DIR_STAGING=staging DATE=${DATE:-`date --rfc-3339=date`} for POST in `find "$DIR_BASE"/"$DIR_STAGING" -type f -name "item.md" -exec grep -Hl "$DATE" {} ;`; do POSTDIR=`dirname "$POST"` cp "$POST" "$DIR_BASE"/"$DIR_LIVE"/`basename $POSTDIR`.txt echo -e 0Latest't'../"$DIR_LIVE"/`basename $POSTDIR`.txt > /tmp/updater.tmp echo -e 0"$DATE" `basename $POSTDIR`'t'../"$DIR_LIVE"/`basename $POSTDIR`.txt >> /tmp/updater.tmp "${SED}" -i "/0Latest/ r /tmp/updater.tmp" "$DIR_BASE"/date/gophermap "${SED}" -i '0,/0Latest/{/0Latest/d;}' "$DIR_BASE"/date/gophermap /usr/bin/rm /tmp/updater.tmp done…
Transferring Large Data Sets Very large data sets present their own problems. Not everyone has directories with hundreds of gigabytes of project files, but I do, and I assume I'm not the only one. For instance, I have a directory with over 700 radio shows, many of these directories also have a podcast, and they also have pictures and text files. Doing a properties check on the directory I see 450 gigabytes of data. When I started envisioning Libre Indie Archive I wanted to move the directories into archival storage using optical drives. My first attempt at this didn't work because I lost metadata when I wrote the optical drives since optical drives are read only. After further work and study I learned that tar files can preserve meta data if they are created and uncompressed as root. In fact, if you are running tar as root preserving file ownership and permissions is the default. So this means that optical drives are an option if you write tar archives onto the optical drives. I have better success rates with 25 GB Blue Ray Discs than with the 50 GB discs. So, if your directory breaks up into projects that fit on 25 GB discs, that's great. My data did not do this easily but tar does have an option to write a data set to multiple tar files each with a maximum size, labelling them -0 -1, etc. When using this multi volume feature you cannot use compression. So you will get tar files, not tar.gz files. It's better to break the file sets up in more reasonable sizes so I decided to divide the shows up alphabetically by title, so all the shows starting with the letter a would be one data set and then down the alphabet, one letter at a time. Most of the letters would result in a single tar file labeled -0 that would fit on the 25 GB disc. Many letters, however, took two or even three tar files that would have to be written on different disks and then concatenated on the primary system before they are extracted to the correct location in primaryfiles. There is a companion program to tar, called tarcat, that I used to combine 2 or 3 tar files split by length into a single tar file that could be extracted. I ran engrampa as root to extract the files. So, I used a tar command on the working system where my Something Blue radio shows are stored. Then I used K3b to burn these files onto a 25 GB Blu Ray Disc carefully labeling the discs and writing a text file that I used to keep up with which files I had already copied to Disc. Then on the Libre Indie Archive primary system I copied from the Blu Ray to the boot drive the file or files for that data set. Then I would use tarcat to combine the files if there was more than one file for that data set. And finally I would extract the files to primaryfiles by running engrampa as root. Now I'm going to go into details on each of these steps. First make sure that the Libre Indie Archive program, prep.sh, is in your home directory on your workstation. Then from the data directory to be archived, in my case the something_blue directory run prep.sh like this. ~/prep.sh This will create a file named IA_Origin.txt that lists the date, the computer and directory being archived, and the users and userids on that system. All very helpful information to have if at some time in the future you need to do a restore. Next create a tar data set for each letter of the alphabet. (You may want to divide y…

Review of the book the Arduino controlled by eforth by dr chen-hanson ting published in 2018 written by chen-hanson ting Late Dr. ting was a chemist turned engineer. he earned a phd in chemistry at the U of Chicago in 1965. taught chemistry in Taiwan until 1975. became a firmware engineer until hI retirement in 2000. he was a forth advocate for more than 50 years, especially a forth called eforth that has been ported to many devices, including the micro chip atmega 328 found on the arduino uno board. I found this book while searching for forths for the arduino uno boards. the source code and documentation for eforth is available in a lot of places I will put a few links in the show notes. I believe I mentioned this forth in an earlier hpr where I talked about choosing a forth. forth interest group https://forth.org https://wiki.forth-ev.de https://chochain.github.io (pdf) When I first encountered dr tings forth for arduino I was interested for one reason, it was easily assembled using avra, the gnu port of the atmel assembler. this was nice because using atmels (now microchips) assemblers on Linux required installing wine and installing wine, in the past, on a 64 bit Slackware meant installing 32 bit libraries to have a multI lib Slackware. ( that not an issue now). assembling the forth code in avra is quick, its only a little bit over 5k in size in the end. After playing with eforth for a while I became frustrated because I could create new words in the dictionary and the examples ran fine, but nothing persisted across reboot. so I dropped eforth and ended up using flashforth, which is a great, robust full featured forth. I still recommend flashforth if your starting out with forth on a microcontroller its solid software with good documentation. At the end of last year I thought it would be fun to write my own forth. and after looking into doing that I revisited 328eforth and thought, no how about I fix the problems with eforth on the arduino. so I dug out the book and began reading. Jones forth port at https://ratfactor.com/nasmjf The book has 6 parts. part 1 is dr tings musings on how he ended up creating 328eforth. part 2 explains installing eforth. the 3rd part begins exercising the arduino board using forth in the interactive interpreter. part 4 explains 328eforth implementation and design decisions. part 5 is the full commented source code of 328eforth and, this is the best part, dr tings explanation of what is going on in the code broken down by functional sections. a gold mine of information! part 6 conclusions The last part is his conclusions and examples to learn forth. This is a great free software project. nothing is hidden. it is accessible to anybody who would take the time to read and dig into the code. its makes assembly language much less dark and foreboding. I'll finish by reading a couple of paragraphs from dr tings book dr ting concludes: People using computers are trained to be slaves. You are taught to push certain buttons, and your are taught to push certain keys. Then, you get employed to push buttons and keys to work as slaves. Computers, programming languages, and operating systems are made complicated to enslave…

In here: 1- Carrying weight more safely - When picking up weight in front of your body, embrace the core (tighten the abdomen); - it gives you more stability, so you are more capable to do the task. 2- Microphone types a) by connection i) USB: connects directly to the computer, in the universal serial bus port. Plug and use! ii) XLR: needs a USB audio interface , with XLR input, to connect to the computer. There are more options of microphones and, if you can spend on an interface, quality is generally better. XLR connectors: female (left) and male. ( Image by Michael Piotrowski / Wikimedia Commons – CC BY-SA 3.0 .) b) by diaphragm i) condenser: captures the voice in more detail, with deeper bass, more detailed treble… Most of the USB microphones uses this technology. As a disadvantage, they catch even minimal sound details of the environment, vibrating with little sound waves around, even distant. That’s why you might get as recording result the clear details of noise from the street, or reverberation (echo) of an untreated room if you use it without the best environment. (If it’s ok for you even in these situations, it’s a merit of other factors, not a merit of the condenser diaphragm) . Usage : A favorite of singers in studio, among several other applications. As you can see on videos of professionals singing, one don’t talk on top of it (which might produce a low and undesired muffled sound) but on the side — and on the correct side, because most models of microphones have a cardioid pollar pattern. A side-adress microphone (captures the sound from one specific side), condenser-type. (Image by Arthur Fox / https://mynewmicrophone.com/diaphragm.) ii) dynamic: responds to the audio source (voice, instrument) very close to the diaphragm, do not capture sound more than some centimeters (or some inches) away. It’s the best for amateur use, or in a room without acoustic treatment. Usage : Musicians performing live use dynamic microphones so the instruments (and crowd) around don’t get their sound amplified by this artist’s microphone. Radios prefer dynamic mics, because it goes to a more impactful voice, rejects eventual sounds from noisy mixers or keyboards nearby that the radio host might be operating. A top-adress microphone (captures the sound from the top), dynamic-type. (Image by Arthur Fox / https://mynewmicrophone.com/diaphragm.) The RE20 from Electro-Voice (not the photo above) is a favorite of radio stations, in part for being dynamic, in part for reducing the proximity effect (that is, the sound “exploding” when the source gets too near to the capsule) because of its technology, named Variable-D. A word about captation pattern (no, the name is polar pattern): it says about the directional response. For example, some are omnidirectional (captures sound equally from all the sides); most of them are cardioid, capturing the sound coming from the front (the speaker, the instrument directed to it), but rejects sound from…

TITLE A Radically Transparent Computer Without Complex VLSI VENUE 1st IEEE Conference on Secure and Trustworthy CyberInfrastructure for IoT and Microelectronics (SaTC 2025), Wright State University, February 25-27, 2025. This is a recording of the final rehearsal that occurred three hours before this invited talk. No slides were used. ABSTRACT Foreign adversaries have colonized America’s computers from at least 1986. Four decades later, online safety is the largest failure in the history of human engineering. Radical stewardship in cybersecurity would bring radical progress, but responsibility for losses will need to flow from the bottom up. The buck stops with victims, who must accept all blame for cyberattacks. Only then will people at risk properly vet the products and vendors they select. A leading challenge in stewardship is balancing the opaque, proprietary nature of VLSI complex logic with the owner’s need for complete control. Since these aspects are incompatible and owner control is essential, it’s necessary to design computers that avoid complex VLSI entirely. One such architecture, Dauug | 36, is being developed at Wright State University to deliver 36-bit computing, preemptive multitasking, paged virtual memory, and hundreds of opcodes, all without using a single microprocessor or anything like one. BIOGRAPHY Marc Abel is an engineer-scientist specializing in technology that supports civil rights, economic security, and geopolitical stability. He holds a 1991 B.S. in Engineering and Applied Science (focused on computer science) from Caltech, and a 2022 Ph.D. in Computer Science and Engineering from Wright State University.

Learning to use the terminal is an important step in becoming a true power user of Linux, but it’s easy (and normal) to make mistakes along the way. Here are the top 5 mistakes new terminal users make, and what you can learn from them. 1. Current working directory When you first open a terminal, your current working directory is your home folder. You have access to all those directories you see in your home directory every time you open a file manager (Desktop, Documents, Downloads, Music, Pictures, and Videos). You can verify your location with the pwd command: $ pwd /home/seth You can list the files and folders within your current directory with the ls or dir or tree commands: $ ls Desktop Documents Downloads Music Pictures Videos But you don’t usually stay in one place while using the terminal. You frequently move from folder to folder so you can open or modify or edit files. It’s easy to get lost, forgetting what directory you’re in and what files are around you. Lesson learned: When working in the terminal, it’s important to regularly verify your current working directory with pwd so you don’t accidentally issue a command you intended to run in a different location. 2. Use interactive options when using wildcards Wildcards are great shorthand to make command entry faster, and to perform bulk actions on lots of files. However, they can be dangerous when you get them wrong. It’s easy to process hundreds of the wrong files by using a wildcard in the wrong directory, or by using a wildcard that’s too broad. For example, suppose you want to run a sed command on all HTML files in a directory, so you run this: $ sed --in-place 's/day/night/g' *ml Job done, until you find out that you accidentally ran that command on all your XML files, too. Lesson learned: Run a safe test command on the wildcard you think you want to target before making a change. Some commands have a literal --dry-run option. Others have an --interactive option that forces the command to prompt you to confirm that you want to carry out the action. Sometimes the logic is reversed: a command refuses to make a major change unless you use a command (for example, sed doesn’t write changes to a file without the --in-place option or redirection). When in doubt, improvise. You can always “expand” a wildcard using the echo command: $ echo ./*ml ./four.html ./one.xml ./three.html ./two.xml $ echo ./*tml ./four.html ./three.html 3. File paths Many new terminal users don’t understand where files are located within the file system. It’s not a common mistake to make on the desktop because there are visual reminders there. You wouldn’t try to double-click on a document to open it if there was no icon to double-click. It’s easy to assume that the terminal application contains all your files all at once, but the terminal is, by design, limited in scope. Were the terminal to…

If you you take a lot of photos, some of them will show problems. But you don't need to throw them away. With GIMP, you can fix these common problems and restore your photos. In this episode I look at getting rid of fingers in photos, fixing red eyes in photos, and fixing common artefacts caused by a speck of dust or damage to the negative.

Maintaining The Remote System I have renamed the project Libre Indie Archive because the name theindiearchive is already someone else's domain. I never would have renamed The Indie Archive but I do think that Libre Indie Archive is more descriptive, hence, better. I am getting close to a pre beta push up to codeberg. Anyone following along who wants to help test, you can do this with two or three old systems. Let me know. Email hairylarry@gmail.com or on Mastodon I am @hairylarry@gamerplus.org. I have decided to develop and document for Xubuntu first and here's the reasons why. I bought an older HP small form factor office system with 4 Gigabytes of ram. HP Compaq 4000 Pro Pentium Dual-Core E6600 3.06GHz 4GB RAM Thirty dollars on ebay with shipping and taxes. I was testing Libre Indie Archive on it. Because of the age of the system Ubuntu wouldn't install. I tested it with some BSD systems and installed Indie Archive without a GUI. Ghost BSD didn't install but Midnight BSD did install so I used the Midnight BSD GUI and installed Indie Archive. None of this was easy for me because I'm a BSD newb and unless you already use BSD I can't recommend it for Libre Indie Archive. Remember, not all indie producers are computer programmers, and I want Indie Archive to work for those producers as well as for the computer savvy. Then on a whim I thought I would try the Xubuntu 24.04 distro and it installed no problems. Thanks XFCE for keeping it light. The other reason I am developing and documenting for Xubuntu is that I can use the Xubuntu install document and install on Ubuntu or Debian with only minor differences. I know because I tried it. This is probably also true for other Debian and Ubuntu derived distributions. So, if you want to help, you could take the Xubuntu install document and see if it works on other distributions. Write down what you had to change and let me know. I plan on making an install checklist out of the install document and it would be great to have a checklist with the actual commands for several distributions. So, that was the intro. Now on to the topic. I am planning on installing remotenear and remotefar systems, remotenear being a short drive away (or maybe in your home if your studio is not in your home, like mine) and the remotefar further away to avoid losing data in the case of a regional catastrophe like flood, fire, tornado, or hurricane. Still even a short drive is not what I want to do any time there might be something I need to check on a remote system so I have devised a way to manage it from the secondary system. When a remote system is delivered to a new location it will be headless. No monitor, no keyboard, and no mouse. At the remote location it is plugged into a UPS and attached to the network with an ethernet cable and attached to the UPS with a usb cable. Then it is turned on. Even without a keyboard or a mouse there is still some local control of the system available. As part of the remote system install we go into the power management settings and next to "when power button is pressed" we select shutdown. So, a short press on the power button initiates a Xubuntu shutdown just like the shutdown that you get from the menu or Alt F4. If that doesn't work a long press of the power button will turn the system off. This is like unplugging the system or losing power and is not recommended but Xubuntu will rebuild the file structure when the system is restarted. And if you do lose power the UPS will send a signal to the computer shutting it down with a controlled shutdown, just like a short press of the…
The most basic security toggle on your Linux computer is the setenforce command. Using just a single setenforce instruction, you can configure SELinux to allow a violation it would normally prevent. There are two states: Enabled and Permissive. By default, SELinux is Enabled (also represented as 1 when using Boolean values). To set SELinux to permissive mode: $ sudo setenforce Permissive When something works in Permissive mode, you've successfully identified the symptom, but you haven't fixed the problem yet. Activate Enforcing mode again: $ sudo setenforce Enforcing Check the status of SELinux You can check the state of SELinux at any time using the sestatus command: $ sestatus SELinux status: enabled SELinuxfs mount: /sys/fs/selinux SELinux root directory: /etc/selinux Loaded policy name: targeted Current mode: enforcing [...] Look at labels and contexts If you have a running Linux system, then you have an example of what SELinux requires for normal operation. You don't have to learn about security contexts or memorize labels. For most anything you try to do on your computer, there are likely already files doing something similar. Use those files as templates. You can look at the security labels of any file you have access to by using the -Z (that's a capital Z) option of ls: $ touch hellotouch hello.txt $ ls -Z hello.txt unconfined_u:object_r:user_home_t:s0 hello An empty file created by a user in the user's own home directory has, as you might expect, a very specific security profile. Even with the executable bit set, that file would not be permitted to run as a systemwide service. It just doesn't have the correct security context. If you use an ll alias, try adding the -Z option to its option list so you get used to seeing SELinux labels. The more you see what labels exist on your system, and how they relate to various system roles, you're more likely to recognize when they're wrong. Copy contexts Suppose you were developing a custom SELinux service for your laptop. You've written a shell script, a service file, and you've placed them in the appropriate system locations. You're also careful to set ownership and permissions correctly. But no matter what you do, you get errors when attempting to start the service. You suspect that SELinux might be preventing an unrecognized service from running. That would normally be appreciated, but in this case you want to make an exception. First, confirm that the service runs successfully with SELinux in Permissive mode: $ sudo setenforce Permissive $ sestatus | grep Current Current mode: permissive $ sudo systemctl start hello.service || echo "fail" $ $ sudo setenforce Enforcing Then look at the files you've created using the -Z and compare them with other files that you know to be working properly. Note the differences: $ ls -Z /usr/lib/systemd/system/hello.service unconfined_u:object_r:systemd_unit_file_t:s0 $ ls -Z /usr/lib/systemd/system/rdisc.service system_u:object_r:rdisc_unit_file_t:s0 The working service (rdisc.service in this example, chosen at random) features the system_u label as well as a special rdisc_unit_file_t label. Suppose you know from previous experience with ls -Z that a common SELinux label for systemd serv…
