Personal and family events take precidence over personal project. However, I’m still satisfied with what I have been abel to accomplish - mainly the recipe sub-site that can help archive family recipe history, and sketches for where to go from here. As an adjacent item, I’ve begun to use Obsidian. While Obsidian itself is not open source, it saves all the core data on local disk as Markdown, and with it’s extensive plugin system and sync between multiple devices, it solves a pain-point or providing access to my main task system on the phone. https://www.r15cookie.com/projects/preservinginfo/2024-04-07-longtermarchive/ Sun, 07 Apr 2024 00:00:00 +0000 https://www.r15cookie.com/projects/preservinginfo/2024-04-07-longtermarchive/ Recipe archiving is continuing slowely. Now that the holiday is over, and before my next big adventure for are yearly work gathering, I’d like to continue a more holistic view of my data archive. Items I’d like to archive My “journal” in markdown format - daily thoughts, etc. My “bullet journal” in markdown format - daily tasks, zettlekrasten, etc. recipe - personal recipe. photos - JPEG formatted photos. As part of this I"ve sketched out a new repo - private for now - that will contain code to replicate the markdown repos, as well as organize, format, and archive the photos. https://www.r15cookie.com/projects/preservinginfo/2024-03-30-image-preservation/ Sat, 30 Mar 2024 00:00:00 +0000 https://www.r15cookie.com/projects/preservinginfo/2024-03-30-image-preservation/ So good progress has been made storing my recipes. Right now I have a collection of public resources (recipes, this blog) and private repositories (A bullet journal for daily tasks, a journal for adhoc writing). But all of these only only encompass text, and in the case of the blog, smaller images I feel comfortable storing in git. What do I do with larger image collections? After some review of git-annex and git-lfs, I realize that I’d rather avoid placing the files in a system that would require external software to review. https://www.r15cookie.com/projects/preservinginfo/2024-03-24-recipe-deployed/ Sun, 24 Mar 2024 00:00:00 +0000 https://www.r15cookie.com/projects/preservinginfo/2024-03-24-recipe-deployed/ With the template complete, I spent last night and tomorrow deploying the family recipe site recipe.r15cookie.com. Deployed as a Github Pages project, it seems to work fairly well. At one point I wanted to automated the deployment more, but given the work to coordinate between Github pages setup, the custom domain, and Cloudflare, in the end it was easy to do manually then to figure out how to coordinate between the three. https://www.r15cookie.com/projects/preservinginfo/2024-03-23-templatefinished/ Sat, 23 Mar 2024 00:00:00 +0000 https://www.r15cookie.com/projects/preservinginfo/2024-03-23-templatefinished/ The main hugo template site is finished! Unfortunately had a LOT of personal sickness/other priorities the drove me away from the project. But in the sprit of finishing this, I want to at least post my recipe site! My thoughts also turn to building out a workflow that would let me work on content or infrastructure from my mobile device. In that way, it would be easy to use small amounts of idle time. https://www.r15cookie.com/projects/preservinginfo/2024-03-13-templatehost1/ Wed, 13 Mar 2024 00:00:00 +0000 https://www.r15cookie.com/projects/preservinginfo/2024-03-13-templatehost1/ Sickness has run it’s course through the family, and unfortunately has prevented me from devoting the time I wanted to. I was able to scoop a little bit of time this morning, and have a functioanl terraform template working. The PR is not merged yet, as I need to get a working Github Action pipeline functional first. Hopefully in the next few days. My overall goal was to make the r15-papercss-hugo-theme easily hostable. https://www.r15cookie.com/projects/preservinginfo/2024-02-24-templatedemo/ Sat, 24 Feb 2024 00:00:00 +0000 https://www.r15cookie.com/projects/preservinginfo/2024-02-24-templatedemo/ While a bit of a distraction, I wanted to ensure my primary template had a good demonstration. CloudFlare’s Pages seems perfect. A generic static website hosting, and has built in support for Hugo. But despite the confiugration made available in the GUI, I was unable to get the Cloudflare working to accept the custom parameters I needed to allow the exampleSite within the template to work. My new plan is to leverage a traditional Github Action workflow to build out the site, then manually upload the assets to Cloudflare. https://www.r15cookie.com/projects/preservinginfo/2024-02-20-updatemainblog/ Tue, 20 Feb 2024 00:00:00 +0000 https://www.r15cookie.com/projects/preservinginfo/2024-02-20-updatemainblog/ A busy day, so just stuck with updating the template on my main blog to match the template update I made on 2/19. Also some minor cleanup, as I no loger have the GitPod links on my readme page. https://www.r15cookie.com/projects/preservinginfo/2024-02-19-templateadjustments/ Mon, 19 Feb 2024 00:00:00 +0000 https://www.r15cookie.com/projects/preservinginfo/2024-02-19-templateadjustments/ Although raw ASCII text is my plan for data preservation, most people would like to view/browse information. Hugo is the static site generator I use for my public site. I’ve had a desire to keep family recipe, and coffee reviews, publically available. With that smaller goal in mind, I updated my hugo template to include recipe and coffee subtypes, as a first step. I should say mine with an astrisk that my template is a copy of the original PaperCSS Hugo Template but was archived last year. https://www.r15cookie.com/post/2024-02-18-perserving-info-kickoff/ Sun, 18 Feb 2024 00:00:00 +0000 https://www.r15cookie.com/post/2024-02-18-perserving-info-kickoff/ Kicking off a 100 Day Project focused on buiding a system for perserving data long-term. Daily blog will ber located in the Perserving Info Project Space. Overall kind of excited - and gives me a nice personal project to grind away at. Good to get back into writing. And this blog serves as a good basis for the project - a complete text representation existing within My Primary and Secondary archive locations, in pure text. https://www.r15cookie.com/projects/preservinginfo/2024-02-18-firstday/ Sun, 18 Feb 2024 00:00:00 +0000 https://www.r15cookie.com/projects/preservinginfo/2024-02-18-firstday/ First day of my 100 day project to perserve information! Most of today was spent building out this project page! In effect this post itself is a representation of what I wish to accomplish - storing data in a format that is accessible for future. In that regard, the raw data is in ASCII format - probably the most readable text format, at a base level. My primary “base” formats will be ASCII for text, and JPEG for images. https://www.r15cookie.com/info/homenetwork/ Mon, 29 May 2023 00:00:00 +0000 https://www.r15cookie.com/info/homenetwork/ Projects and links more related to home networking than professional ops Home Automation Ultimate Home Server - Massive Helm chart for a homelab, designed for a single-node k3s deploy https://www.r15cookie.com/post/2022-08-22-generic-dex/ Mon, 22 Aug 2022 00:00:00 +0000 https://www.r15cookie.com/post/2022-08-22-generic-dex/ Samsung Dex is a Samsung solution to let one interact with your phone on a full size display, either with a dedicated dock or a software application. I’ve always though about getting one, but the use cases were pretty mimimal, thus making the $100 spend a little hard to stomach. Last night I found myself in our office at home with no laptop. I almost went through with purchasing a dock, but then found a reseller that had a “Dex Compatible” dock that looked suspiciously like a plain USB-C hub. https://www.r15cookie.com/post/2021-08-18-chromeos-linux-out-of-beta/ Wed, 18 Aug 2021 00:00:00 +0000 https://www.r15cookie.com/post/2021-08-18-chromeos-linux-out-of-beta/ Linux support for ChromeOS has been great. But the “Beta” moniker has always been a bit concerning. Google I/O this year claims that it was going to be out of beta soon. Although suppose to happen by may, I just noticed it with ChromeOS release 92 this month. Great news alongside my CKA accomplishment! I encourage anyone who is even modestly technical to give the Linux ChromeOS experience a try The most important item is that, unlike the rest of the ChromeOS experience, anything done on the Linux layer and it’s apps are not automatically backed up. https://www.r15cookie.com/post/2021-08-15-cka/ Sun, 15 Aug 2021 00:00:00 +0000 https://www.r15cookie.com/post/2021-08-15-cka/ I’ve passed the CKA certification! It’s been a while since I’ve obtained a certification. Reading about the CNCF’s Kubernetes certifications, I was quite excited that it’s a hands-on exam that required interactive with live clusters to demonstrate one’s knowledge. As part of Kubecon last year I purchased the exam at a discount. With the upcoming birth of my child, I wanted to make sure to have the certification done before my life is consumed by diapers and bottles. https://www.r15cookie.com/post/2021-05-09-human-interface/ Sun, 09 May 2021 00:00:00 +0000 https://www.r15cookie.com/post/2021-05-09-human-interface/ Browsing the Internet at random, I came across a great Hugo theme based on PaperCSS. The human feel of the typeface and layout really pulled me in. My desire is to make my blog approachable. So I begin with the theme, but overall will aim to make sure my content itself is approachable and easy to consume. https://www.r15cookie.com/post/2021-03-20-chrostini/ Sat, 20 Mar 2021 00:00:00 +0000 https://www.r15cookie.com/post/2021-03-20-chrostini/ With a recent update to 89.0.4389.82 of ChromeOS, there was also an update to the underlying container that hosts Linux. Normally if this happens it’s a relatively short process. However, a few days ago this took far longer, and ended up with a “Error starting penguin container: 58” message. Not helpful at all! Fortunately with some searching, I found the solution on Masaki Muranaka’s blog. The article is in Japanese, but fortunately Google translate was able to work well enough for me to get the steps necessary to fix the issue. https://www.r15cookie.com/post/2021-01-02-loki/ Sat, 02 Jan 2021 00:00:00 +0000 https://www.r15cookie.com/post/2021-01-02-loki/ Happy 2021! And to get the year started, let’s look at some modern logging stacks! I love modern application and stack observability. Anyone that remembers the old days of stringing together Nagios and Syslog into a cobbled-together stack can certainly sympathize. Now solutions exist that provide a more integrated experience across metrics, logs, and tracing. Today I’ll be concentrating on the logs component with Grafana’s Loki, and demonstrate that stack on a Civo k3s cluster. https://www.r15cookie.com/post/2020-05-31-androidgitopswriting/ Sun, 31 May 2020 00:00:00 +0000 https://www.r15cookie.com/post/2020-05-31-androidgitopswriting/ My sister got me a Logitech K480 Bluetooth keyboard for Christmas! What makes me truly excited about this gift is the mental exercise of using my Android phone as a content creation device. It’s a bit of a stretch, but with this kind of powerful technology in our pockets, we should be able to leverage these devices more productively. My writing workflow is focused around markdown stored in git (backed by Gitlab or Github), rendered using Hugo, and leveraging Netlify’s platform for integration and deployment. https://www.r15cookie.com/info/proxyserver/ Sun, 03 May 2020 00:00:00 +0000 https://www.r15cookie.com/info/proxyserver/ DNS Blacklists Not quite a proxy server, but similar functions with a little less configuration required for end clients: PiHole: Extremely popular drop-in to block Ads and Spyware.

With that acquisition, the Android and Web app will be discontinued by July 2020, and the API by the end of 2021. I appreciate that they are giving some time for people to find alternatives, especially on the API side, where I know apps and sites have built heavy integrations with Dark Sky. I am disappointed that Apple is shutting down this innovative app for everyone except Apple customers. https://www.r15cookie.com/post/2020-01-07-githubarchive/ Tue, 07 Jan 2020 00:00:00 +0000 https://www.r15cookie.com/post/2020-01-07-githubarchive/ Want to preserve your writing and code for future generations? Then check out the Github Archive Program at https://archiveprogram.github.com/. Github will archive all active public Github repos for storage in the arctic that is estimated to last 1,000 years.

What a pain! Fortunately, I had a password manager to help out, but that still did not reduce the 5-10 minutes per site to log in, find where to change the password, actually change the password, and verify the new password worked! It was a good exercise, but the idea of regularly rotating passwords for all of my accounts is pure lunacy. https://www.r15cookie.com/post/2018-10-31-newtagline/ Wed, 31 Oct 2018 00:00:00 +0000 https://www.r15cookie.com/post/2018-10-31-newtagline/ Today I picked a new tagline for my site, referencing “an appreciation for simplicity”. I think one of my main attractions to the Unix philosophy is a fundamental simplicity…which may sound strange for those that are just coming into Unix/Linux for the first time, and perhaps have not had a lot of exposure to the command line. By providing a toolbox of single purpose commands that each to their singular tasks well, an administrator can put those together to fit the perfect solution. https://www.r15cookie.com/post/2018-09-06-2018blogmigration/ Thu, 06 Sep 2018 00:00:00 +0000 https://www.r15cookie.com/post/2018-09-06-2018blogmigration/ My blog migration is finally complete! The technology stack I’m using is an exciting progression of the theme of the last few technology stacks I’ve used. I’ve always attempted to stick with formats that would be good long-term archives of my data. The stack should be open, with the ability to easily move hosting providers or even core parts of the stack. The newest platform stack that I’m using: The core of the site is kept as markdown, but I’m now using the Hugo static site generator. https://www.r15cookie.com/post/2018-04-27-embedded/ Fri, 27 Apr 2018 00:00:00 +0000 https://www.r15cookie.com/post/2018-04-27-embedded/ As part of a recent vacation, I decided to finally go through my collection of embedded devices, and get them all up and running! I figure this will provide a nice repository of available devices for any upcoming electronics projects. With a new child on the way, I’ll certainly have less time to devote to these projects, but it still makes a great hobby.

Let’s Encrypt is a project sponsored by EFF, University of Michigan, Mozilla, Cisco and Akamai to provide free, signed TLS certificates. While I’ve used StartSSL in the past for free certificates, I’ve found their process a bit cumbersome (although in all fairness, they have done a ton of redesign this year). https://www.r15cookie.com/post/2016-07-06-chrome-hung-tasks/ Wed, 06 Jul 2016 00:00:00 +0000 https://www.r15cookie.com/post/2016-07-06-chrome-hung-tasks/ A few months ago I noticed a weird issue on the Chromebook where it would reboot hard if I performed a dd operation to write a Linux distro out to USB. I didn’t think anything of it at the time. Browsing around the crouton source code for an unrelated project, I came across this section of code that explains the issue. The Chromebook OS has the hunk_task_panic timer set for 2 minutes. https://www.r15cookie.com/post/2016-02-06-sparkcore/ Sat, 06 Feb 2016 00:00:00 +0000 https://www.r15cookie.com/post/2016-02-06-sparkcore/ I recently purchased a Spark Core development kit at Micro Center last week. The Spark Core is a cloud development board. Normally I try to avoid any cloud platform that may lock me into a vendor, but as Particle (the company) fully releases source code for the schematics, firmware on the device itself, and a node.js implementation of the server side, it seems like a very safe platform for development. https://www.r15cookie.com/post/2015-11-11-chromeready-virtualbox/ Wed, 11 Nov 2015 00:00:00 +0000 https://www.r15cookie.com/post/2015-11-11-chromeready-virtualbox/ The ChromeOS has been a great experience so far. One problem, however, is that you generally need to purchase a Chromebook to use it, or go through compiling the ChromeOS from source. A few days ago I came across Neverware’s CloudReady, which provides an freely available (to individuals) ChromeOS experience on generic hardware. Cloudready, however, does not support dual boot, so it will wipe away anything on the machine. Following some hints from this page I was able to get the CloudReady to install on a Virtualbox VM, without the need to create a USB bootable drive. https://www.r15cookie.com/post/2015-09-07-continuous-delivery-ops/ Mon, 07 Sep 2015 00:00:00 +0000 https://www.r15cookie.com/post/2015-09-07-continuous-delivery-ops/ Continuous integration, continuous delivery, and test driven development are pretty common on the development side of the house. In many organizations, however, operations still has too many instances of building and maintaining systems by hand.

It was in a RAID, so there was no data loss. But as I had to shut everything down to replace hardware (no hot swap…), it makes me think about also maintaining the software stack for the lab. Currently I have two physical systems that are libvirt/KVM hosts for my virtual machines, including the main firewall and fileserver. I’ve had my eye on a few newer technologies, so the lab layout requires maximum flexibility. https://www.r15cookie.com/post/2015-07-16-ansible-automation-server/ Thu, 16 Jul 2015 00:00:00 +0000 https://www.r15cookie.com/post/2015-07-16-ansible-automation-server/ I’m fairly fond of Ansible as a light-weight configuration management tool, but I am always on the lookout for additionally tooling that will make it a bit easier to manage centrally…well, without paying for Ansible tower. I came across Ansijet and was pretty exciting. It provides a REST API to Ansible itself, as well as storing results in MongoDB.

Why? My original blog/wiki was build around Dokuwiki. I liked the idea of having the core data in text format, and not in a database that would be tied to a specific version of whatever blogging software I happened to be using. While dokuwiki has served it’s purpose, it’s not primarily a blogging platform, and I worry about the long-term maintenance of the Dokuwiki codebase. https://www.r15cookie.com/post/2015-04-26-chromebooks-open-rar/ Sun, 26 Apr 2015 00:00:00 +0000 https://www.r15cookie.com/post/2015-04-26-chromebooks-open-rar/ I’m still compiling my large list of tasks, and hope to break them out blog posts/wiki documents. But the coolest thing I’ve come across so far is that the Chromebook can open up Rar files! Rar compressed files are not too common, but nice to know it’s one less item I’ll have to depend on another machine to perform. https://www.r15cookie.com/post/2015-04-08-chromebook-experiment/ Wed, 08 Apr 2015 00:00:00 +0000 https://www.r15cookie.com/post/2015-04-08-chromebook-experiment/ Due to the alignment of some stars financially, I went out and obtained a Chromebook for practically free! Specifically I am getting a Toshiba Chromebook 2. Although I tend to lean more toward open source OSes and non-cloud services, I want to explore the feasibility of actually using a lightweight laptop for regular purposes.

It’s an interesting discussion on the power of these companies, and the compromises users submit to for the sake of convenience. I myself can completely understand, using Google Apps for the email of this domain. Google has an easier time tracking me with the amount of services I use from them. However, I think the cultivation of serviceable options, as well as “…encouraging as many people as possible to find ways to take control for themselves…” is a good idea to keep in the forefront of the public mind. https://www.r15cookie.com/post/2015-02-18-vagrant-windows-base-boxes/ Wed, 18 Feb 2015 00:00:00 +0000 https://www.r15cookie.com/post/2015-02-18-vagrant-windows-base-boxes/ Vagrant is one of the most useful tools for automating the build of Virtual environments for testing and development purposes. I’m usually a Linux/Unix type guy, but on occasion it would be nice to be able to test Windows.

Storing important data in the cloud seems a bit risky. However, Springpad is doing an excellent job of providing ways to export your data. Evernote migration is even being supported, allowing a very easy migration path. For now I’m moving all that data over to Evernote. I personally follow a rule that any cloud-provider needs to provide an easy way to export their data in the event that they do close down. https://www.r15cookie.com/post/2014-06-04-blog-spam/ Wed, 04 Jun 2014 00:00:00 +0000 https://www.r15cookie.com/post/2014-06-04-blog-spam/ I left anonymous comments on when I updated dokuwiki, and got hit with comment spam!

Most of this is expressed in Eric Raymond’s [Art Of Unix Programming]((http://www.faqs.org/docs/artu/). The fundamental principle is “Keep It Simple, Stupid”. Complexity begets large, inflexible systems that are difficult to change and debug. Simplistic systems are more flexible, more robust, and easily combined to perform larger tasks. “Controlling complexity is the essence of computer programming” [Kernighan-Plauger] (From the Art of Unix Programming).

The Bluetooth RFCOMM method is a bit more open. https://www.r15cookie.com/projects/moomachine/languagereference/ Tue, 03 Aug 2010 00:00:00 +0000 https://www.r15cookie.com/projects/moomachine/languagereference/ The Moo Machine uses the code integer for instruction entry and display. Most program demonstrations use the actual instruction, which is easier to read. (from https://bigzaphod.github.io/COW/ Code Instruction Description 0 moo This command is connected to the MOO command. When encountered during normal execution, it searches the program code in reverse looking for a matching MOO command and begins executing again starting from the found MOO command. https://www.r15cookie.com/projects/moomachine/program/ Tue, 03 Aug 2010 00:00:00 +0000 https://www.r15cookie.com/projects/moomachine/program/ The interpreter and interface logic was written in C, using the Arduino libraries and IDE. More information is available at http://www.arduino.cc/. The Arduino Mega is the target platform. Source code for the version I demonstrated is located on Github, specifically for version 0.9. The full repo is at https://github.com/ssmiller25/moomachine/ https://www.r15cookie.com/projects/moomachine/schematic/ Tue, 03 Aug 2010 00:00:00 +0000 https://www.r15cookie.com/projects/moomachine/schematic/ The support circuitry for the Moo Machine is fairly simplistic. The left diagram shows a standard input circuit, which will be replicated nineteen times for each toggle switch. It is a standard pull-up configuration for both sides of the switch. The output circuits are represented by the right side of the diagram. Those circuits will be replicated 26 times for the various LED outputs for the project. https://www.r15cookie.com/projects/moomachine/technicaloverview/ Tue, 03 Aug 2010 00:00:00 +0000 https://www.r15cookie.com/projects/moomachine/technicaloverview/ Hardware The Moo Machine is based around the Arduino Mega development board. An overview of the electrical components can be located here. The digital input and output pins on the Arduino are all that is necessary for the user interface. The input circuits is a pull-up design, with debouncing logic contained within the code. The outputs are simple LEDs. The Arduino Mega (ATMega 1280) provides enough input and output pins directly for the project. https://www.r15cookie.com/projects/moomachine/demostration/ Tue, 03 Aug 2010 00:00:00 +0000 https://www.r15cookie.com/projects/moomachine/demostration/ Two physical Moo Machines will be available for hands-on demonstrations. The first machine will be a scale-model of the Altair 8800. The physical layout and experience will attempt to match the Altair 8800 as closely as possible. A second machine will be a scaled down portable version, maintaining as much of the interface of the full scale model as possible. The Cow Programming Language will be used in lieu of the original 8080 machine language of the Altair 8800. https://www.r15cookie.com/projects/moomachine/exampleprogram/ Tue, 03 Aug 2010 00:00:00 +0000 https://www.r15cookie.com/projects/moomachine/exampleprogram/ Below are several example programs.
