Today I will talk about digitizing analog photos. I will talk about two methods. I have scanners from different manufacturers, flat bed scanner and dedicated film scanner. Each scanner is delivered with software. Each software is generally good. But it is a problem to manage several software. Secondly, none of them works for Linux operating system. I wanted to simplify my software learning, so I wanted one software for all my existing and any future scanner. Secondly I intended to migrate to a Linux operating system, which I now have done. Those two requirements lead me to switch over to VueScan software. I had tested VueScan before and also gotten recommendations from photographic friends. VueScan is a proprietary software made by a small family run company. It’s available for Linux, Windows and macOS. VueScan supports very many hardware scanners. I do not know about any better software for Linux and is maybe also the best choice for any operating system. I do not regret my switch to VueScan. A second method to digitize photos is reproduction with a camera. That is to use a camera to shoot a photo of the photo. Some say it is the superior technology. I don’t know. But as I am coming from the scanning technology and starting to explore the repro technology, I will give my early thoughts from that perspective. My initial plan has been to use repro photography for prints that are glued into albums and therefore difficult to manage in the scanner. It is also an excellent method to digitize other papers in book format. But I have not really started to do that. However, a while ago I started to look into 6x9 cm negatives. My scanner can just manage 6x9. But I do not have a fixture for 6x9. So it is both somewhat tricky to position the negative as well as to keep it flat. A thin plexiglass plate might be possible to use to keep it flat. Even without plexiglass, I have tested I can get well acceptable result with the scanner. I started to try out the repro method. I have not come so far in my trials that I can decide which is the best method for me. My camera is a modest camera compared to state of the art. My flat bed scanner should give better or comparable resolution than my modest digital camera. The fixture I have for repro do not keep the negative fully flat, because 6x9 is a rather big size. So I plan to explore if I can improve quality with a plexiglass plate above the negative. An issue with the repro method is to keep all angles in control, to mount the camera in exactly correct angle in relation to the object. Focus can also be another issue. I consider it is better to use manual focus rather than auto focus. When I take the repro photos, I have the camera connected to a laptop and I use the Entangle software to control the camera settings. I can use the camera live view to position the object as well as to focus. I use RawTherapee software to convert the negative photo to a normal photo. RawTherapee comes with pre-installed profiles for this process. The default profile values can be adjusted and also stored as new personal profiles. A major advantage of the repro method compared to the scanner method is the speed. Once all is configured, it takes one hundred of a second or so to do the digitize itself, while it can take minutes with the scanner. I use digiKam as my photo catalog software. All software I currently use with the exception of VueScan are free and open source. I use all on Linux operating system, some of them are available on other platforms. I include links to their websites in the show notes. If you have any opinion or experience on digitizing analog photos, I will be happy to read your comments or listen to your show.

HPR4357: Short introduction by murph.

4 gün önce

This show has been flagged as Clean by the host. 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. Provide feedback on this episode .…

HPR4355: Record player audio - Streaming with Darkice

8 gün önce

—

This show has been flagged as Clean by the host. 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 Cynthiana,KY ricemark20.nospam@nospam.gmail.com Change the passwords from hackme to a more secure password hackme hackme admin hackme 192.168.x.x 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 = Podcast # genre of the stream public = yes # advertise this stream? localDumpFile = recording.ogg # Record also to a file metadata = yes # enable metadata What is Darkice? DarkIce is a live audio streamer designed to record audio from an audio interface, such as a sound card, encode it, and send it to a streaming server. It supports various streaming servers including IceCast 1 and 2, ShoutCast, and Darwin Streaming Server. DarkIce can encode audio in formats like MP3 and Ogg Vorbis. To use DarkIce, you configure it with settings such as the audio input device, sample rate, and streaming server details, including the server’s address, port, and authentication information. This description of Darkice is a result of using the Brave Search LLM, or Large Language Model . The default config file is located in /usr/share/doc/darkice/examples/darkice.cfg.gz and is copied to the /etc directory. From there, use the gunzip command, for example gunzip darkice.cfg.gz I used the config file from a blog by Steffen Müller on stmllr.net August 10, 2012 as a template for my configuration darkice.cfg This is the configuration I used in the end. darkice-pi.cfg Changes to the template The audio device is configured in the [input] section, defined by arecord dash lowercase ‘L’ to list the capture device, which in my case is the Behringer UMC202HD USB Audio Interface [general] duration = 0 # duration of encoding, in seconds. 0 means forever The section of the config file for audio input looks like this. [input] device = plughw:0,0 # This refers to card 0, device 0 Start Darkice darkice & Update Metadata I was looking for a way to update the Currently Playing metadata, but my coding skills are not too good. For this, I used Claude.ai to generate code from the prompt: BASH script to send HTTP request to change metadata on icecast stream update-metadata.sh Default values HOST="localhost" # 192.168.x.x PORT="8000" # Default Icecast port MOUNT="/stream" USER="admin" PASSWORD="hackme" # Icecast admin password SONG="Unknown" Usage update-metadata.sh -s "HPR Test" If there are any suggestions for improvements, please leave a comment or upload a show. I look forward to hearing about if an how other people are using a personal streaming server. Also, I am looking forward to the show from the Reserve Queue, 2024-10-13 Fred Black What LP records do I have Other References Radiostreaming for Beginners Provide feedback on this episode .…

HPR4350: GIMP: More Photo Fixes

15 gün önce

—

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.

HPR4348: Resizing the root partition on a PC

17 gün önce

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…

What is Scratch? Who made it? How does it work? What can it do? What are the blocks and how they relate to coding? Can be dragged and placed Different shapes/colours represent different aspects Round ones are analogous to Functions Sharp ones are variables Control ones are Logic/Conditions Why is this good? Allows kids to focus on logic and the mindset of coding without having to learn or care about Syntax/lines of code Allows for direct visualisation of what the code does My own experience Started with blocks in Lego Mindstorm Evolved to C HTML/PHP and then Python The workshop Kids made 2 games that covered all basics Triggers/Input Functions Variables Were all customised by them Explain that each kid made their version the football crazy one turned my cat and balloon game into a Football Match They got to take them home The games covered the basics on this way Input using keyboard for triggering functions Use Functions to modify location parameters If/Then Conditions for when sprites are touching each other/the walls Variables for storing points Operands to increase Points in variable End conditions Loops for permanently checking the If/Then Conditions Ask about the organisation Mora Mundus Download and learn more about Scratch .…
