Many distributions do not provide a source ISO to match their installation media. Debian provides one, as does Oracle. As far as I know, those are the only two that do that. Since the GPL requires one to redistribute the source code with the program, one needs to possess a copy of that source code [...]

It can be difficult to add a secondary storage to Nextcloud if the storage location is a new local drive. Authentication errors abound and leave one unable to use the additional space. To resolve this, add the drive to the system, and use the occ command to add the secondary storage. Add the new drive, [...]

Apostrophe on Linux fails to show the preview in some newer operating systems. This occurs because the WebKit backend switched to using hardware acceleration and this does not work for many users. A fix to the launching command works to bring the preview back to Apostrophe, but the same fix will not work for Epiphany. [...]

The quantity of spike protein created via the mRNA transfection process in humans continues to grow. This case shows that at 3.5 years, the lack of an off switch allows continual gene expression.  This means that individuals may express that gene and produce those proteins indefinitely. This case documents the longest reported in vivo persistence [...]

Joshua Stylman’s essay on refusing to give the digital identification is a great read and definitely worth sharing. The system requires your participation to work. The catch is that this may also be its biggest weakness. It only becomes a cage when adoption is near-universal. In other words, when opting out means you can’t participate [...]

Discernment regarding the technology choices that one makes continues to remain important.  In many cases, doing away with social media entirely is the best choice.  Freedom and knowledge for posterity is given up bit by bit. The infrastructure for systems in which you “cannot buy or sell without an ID” is being assembled one prompted [...]

It is possible to configure the behavior of Linux with regards to the use of swap memory. The default setting is a swappiness of 60, which means the kernel begins using swap memory once processes use 40% of the system memory. To view the current swappiness setting, use the command cat /etc/sysctl.conf | grep swappiness [...]

This page contains details on the numbering conventions for my zettelkasten. For purposes of organization, these are case insensitive. Sometimes I write them in all capitals and sometimes in lower case. All notes identifiers start with the letter z. That is because Joplin requires a character rather than a number in order to search. Then [...]

Linvega contains excellent information on historical computation devices such as calculators and slide rule mechanical calculators. Scientist Sees Squirrel convers the importance of writing from the perspective of an evolutionary ecologist and entomologist in Canada.

The Mathematical Reason Most People Never “Make It” is an article that details why it is necessary to create, even when it seems that the payoff is lower than it should be. Price’s Law states that the square root of the number of people in a domain does 50% of the work. Here’s what that looks [...]

Redshift was not installed on Debian 12, yet color temperature kept changing without manually doing it.  xsct 6500 restored default color temperature.  Switching to a Gnome session and disabling night shift worked.  After logging back into xfce the temperature issue returned. dconf reset -f / brought back the normal color temperature.

  Disabling Microsoft 365 Copilot from Startup on Windows 10 is a bit of a challenge for those familiar with Windows from the old days. It does not appear in Autoruns anywhere, nor does it appear in MSCONFIG. It only appears in the task manager startup section.[1] I have done this to run H & R [...]

The 2026-03-24 Tiny Takeover Java Edition, 26.1, requires an upgrade to Java 25. The previous release, 1.21.11, used version 21.

The Castle is a book by Franz Kafka.  It entered the Public Domain the United States.  It is a wonderful book. I picked one up at a Friends of the Library book sale. That is one of those sales where American libraries sell their old books.  Most American Libraries keep no old books.   When Ceasar [...]

More links have disappeared from the blog roll.  They were links to blogs with callous hunger for death and thirst for human tragedy. Time is too valuable to waste it reading the mantras of the scrofulous.

This article details how to customize the user interface on Debian using IceWM and picom, and includes a useful font. This applies to Debian 12 at present and applies to any installation of IceWM and Picom as of this date. The version of IceWM used is 3.31, which is copyright 1992-2012 Markko Macke, and 2001 [...]

I added the Westminster Lenigrad Codex to this site.  The continuously revised version is at https://tanach.us/.  A 713 MiB PDF file is available at archive.org. A set of color photographs by Bruce E. Zuckerman is also available. In order to faciliate easy links, I have uploaded a reduced file size version of the 713 MiB PDF.  [...]

Upon checking for the word childish using grep on the server I stumbled upon a drastic difference in translation meanings. Wisdom, Chapter 4 in the KJV, says “Better it is to have no children, and to have virtue: for the memorial thereof is immortal: because it is known with God, and with men. ” Whereas [...]

Many of the links are disappearing from the blog roll.  Long format text blogs are a rarity these days, but the ones removed have express Trump Derange Syndrome, which is not a medical diagnosis.  It means they are either paid to lie, delusional, or an enemy of heritage American posterity.  That is not to commit [...]

What is the reason for a document on backing up one’s data?  The reason is that this is a critical thing that one must get handled, out of the way, and automated in order to possess peace of mind while undertaking a comprehensive work involving data.  For years I have searched for a great piece [...]

This is my first attempt at weekly posts. I created an organizational schema and setup the files to begin the work. One of the things this week that I accomplished was the use of Aider to create a rapid prototype of a paired comparison analysis tool that works on the console in any operating system [...]

This is a simple paired comparison analysis to compare a list of items amongst themselves to find a ranking for decision making.   #!/usr/bin/env python3 ####################################################### # Paired Comparison Analysis # webmaster@memorymatrix.cloud # 25.26.12.2053 ####################################################### import sys import logging def create_lists(list_a=None, list_b=None): “”" Create two lists of items from user input Args: list_a (list): Initial [...]

Well it has taken a little bit, but thanks to Getting Things Gnome! (GTG!), I installed Aider and Ollama and began some vibe coding. Prior to this, I have written data science code in Python and R and produced some GUI applications for Linux. I also developed some software that is in the Windows store, [...]

I love Joplin, but Joplin seems more like an incredible file cabinet and set of bookshelves. It is possible to link from one note to another, but a Joplin icon appears by that link in the text. It can also be cumbersome to navigate between multiple documents while working on one. Joplin recently added the [...]

It is a very challenging thing to pick a tool to invest time into building a personal knowledgebase. I have used numerous tools over the years and collected a huge number of documents and notes. Logseq integrates with Zotero which might prove useful due the gigabytes of material that I have stored there. My plan [...]
