Triggering a Slack Notification on Completion of a Task Sequence

Screen snip (sanitized) of a completed task sequence Slack notification

A number of years ago I started having my primary OSD Task Sequences "check in" as one of their last steps. Specifically check in with key information so I can follow up as necessary ("trust but verify") with downstream actions to ensure our asset management systems are properly updated.

I chose a Slack webhook to accomplish this as I could set up a quiet channel for notifications and queue them for later review (once a day or a few times per week).

Creating a Generic OAuth Token Request to Microsoft Graph API

After spending much of the month of August on a European vacation, I'm back and preparing for my sessions at MMS Flamingo Edition coming up in October. The last couple weeks I've been working on demos for my Admin Service and Graph API session in which much conversation (and many demos) will take place working with "read-only" data from both of these services to empower T1 folks.

Exporting Full MySQL Database Tables on Ubuntu

...or, How I Suffered Through an 'If it Can Go Wrong, it Will Go Wrong' Scenario for a One-Off Export of Database Tables

This is one of those posts I'm writing up because in the moment I was so incredibly frustrated about how unnecessarily complex this action was, and I still have the various browser tabs that ultimately provided me the necessary bits open. I write this mostly for Future Me should I need to do something like this again.

Basic Dialog to Manually Name OSD Task Sequence Device

Many years ago I wrote about the way I automatically generate the OSDComputerName value for most devices in my fleet. Much of that process remains as it did back then, but I've never written about how I handle the one-offs (such as my testing VMs or other nonstandard hardware).

Setting Up SSH Key Authentication: 2024 Edition

A recent project I worked on required setting up more SSH key authentication, and seeing as how I'd not written about it for two years since the last iteration, it seems fitting to do another quick primer on setting that up for SSH...the 2024 edition.

Automatically Process and Send Google Form Responses on Submission

Screen snip of a dynamically generated PDF from Google Form submission

I haven't written anything up about Google stuff in a while, and since this topic came up a few times in as many weeks (including from conversations at BrainStorm K20) I figured it's time to share the solution I've used several times.

Lighting the Dark Days of Winter with Home Assistant

Screen snip of two settings in Home Assistant for Light state and a script trigger

This fall, right after the time change, I found myself often working intensely enough to suddenly notice "it was dark outside" in the late afternoon. Good for productivity, I suppose; not so much otherwise? ¯\_(ツ)_/¯

I'd automated a whole bunch of other light situations, mostly with some combination of brightness level (obtained from my Tempest weather station) and/or time-based. But all of those solutions were "binary" (on/off). My thought here was to slowly and incrementally bring up the overhead smart lights in my home office space.

Reflections on Advent of Code 2023

Screen snip of a portion of the AoC "map" for 2023

I finally gave Advent of Code a shot for 2023! In years past I'd think about/stumble across/remember it a week or two in and automatically 'nope' out of starting. This year, in large part due to the WinAdmins Discord, I was both reminded of it in advance and also had a small community of other folks taking part (and a private leaderboard to watch).

OctoPrint Webhook for Filament Change Notifications

MMS Miami Beach Recap

Rudy (at left) and Matt take a quick picture from the speakers' angle of the "Big Room" at MMS Miami Beach as we begin our 8 a.m. session.

I had the great honor and pleasure of being a speaker at MMS Miami Beach Edition at the end of October. It was the first speaking event I've had since 2019, largely due to the pandemic, and the experience was marvelous! The entire team behind MMS is outstanding, and their attention to detail really makes a difference in the experience both for attendees and speakers.

The Overall Experience

The speaker attire this edition was pretty rad: lots of flamingo gear!

Enabling Pi-hole DNS Across Multiple VLANs

Screenshot of the "Top Clients" dashboard box of the Pi-hole admin interface, showing six clients with their local dns addresses and activity.

I recently (and finally) upgraded my home network to a UniFi system after years of consideration and an incorrect assumption it would cost a small fortune to enact. My existing "core" router was reaching the end of its normal life, though, and I wanted a real mesh network with better outdoor coverage instead of using the range extender during the "not winter" months and connecting to a different SSID.

Turn off the fan already! Tales of an automation modification

Snip of details when creating a Home Assistant helper entity for a timer object.

It's been a couple months since my last post, and while I had some things in the queue I have lacked time to finish them out due to MMS in early May, being involved in a community theatre production that just wrapped up a couple weeks ago, and for random reasons building a chicken coop of all things. ¯\_(ツ)_/¯

Here's to a return of more regular posts, assuming I have adequate time to write and revise them!

Addressing Firmware Updates for Dell Latitude 54X0 in a Task Sequence

Screenshot of a child task sequence for updating firmware in Full OS mode, with a Run PowerShell Script step highlighted with package and script information.

For about two years we fought with getting firmware (BIOS) updates to install on our Dell Latitude 54X0 models during their build/rebuild using a MEMCM task sequence. No matter what random trick I tried or thing I read, I just couldn't get the update executable to successfully apply the update in our primary build/refresh task sequence. Our techs (self included) would have to apply the update manually after devices were [re]built.

Semi-Automatically Offering Dell BIOS/Firmware Updates

Photo of Dell firmware update in progress instructing a user not to power down the system and showing a progress bar with basic status information.

Several years ago I implemented a mechanism in our primary [re]build [Configuration Manager/MEMCM/SCCM] task sequence to address upgrades of our fleet's firmware (BIOS). On the whole, the process has worked very well and definitely helped keep things updated. However, this process only upgraded device firmware during a [re]build cycle which works great for our multi-user devices receiving an annual refresh; for high-affinity devices a rebuild happens once every 3-5 years and is usually associated with some form of attrition or replacement.

Creating a Reference Sensor Template in Home Assistant

Snip of a Home Assistant Dashboard item identifying two sensor states: one for bathroom humidity at a level of 44.6% and another for bathroom humidity target at level 49.0%.

It's been a while since I wrote about any Home Assistant stuff so I figured this was as a good time to write about something I'm super happy with: custom/reference sensor templates!

Going Dual Camera with OctoPrint

Almost as soon as I started using OctoPrint, I also set up an old webcam to let me remotely "see" things since I keep the printer in the basement. That whole process was an adventure, because I don't use a Raspberry Pi for OctoPrint like most folks; I have an old Intel NUC (also used as a local dev server) running Ubuntu on which I installed OctoPrint. To that end, I had to do some manual install/build of the mjpg-streamer, specifically I used this package to get started.

Upgrading All The Things to Ubuntu 22.04

One of my "winter break" projects this year was to get all of my disparate Ubuntu server instances upgraded and into parity. Last year I wrote about my adventure moving WSL Ubuntu from 18.04 to 20.04, which happened before 22.04 was officially released. In that process I noted the longer-term target of moving to 22.04 which brings us to the here and now!

Mister Thermistor, Fixed With a Silpat

I got hooked into 3D printing late last summer. A problem that cropped up after the first couple months of tinkering and relatively error-less printing was an issue with thermal runaway. Something I could correct for short periods of time, but never make totally go away...

Powershell String Manipulation - A One-Liner

See also: asking a friend for help can save oodles of time and effort.

Around Thanksgiving 2022, an friend of mine asked to talk through a problem he thought might be solvable with Powershell, but he'd been stuck on the design. Naturally, I agreed to help out if/where I could and it provided an opportunity to chat via Zoom which I am not one to turn down.

The Problem

In this case, there's a relatively free-form bunch of text received from a person/process whose behavior is unlikely to change. A couple of things that are consistent in this data:

Smart Independent Control of a Ceiling Fan & Light with Shelly 1L

Home Assistant dashboard (dark mode) illustration for independent control of office fan and office lights, with office fan in "off" state and office lights in "on" state.

As I've noted before, my 1940's-era house has its own quirks with regard to smart home automation in large part due to 1940's wiring standards.

Smart Control of a 1940's Three-Way Switch with Shelly 1L

Snip of Home Assistant dashboard card for Stairwell/Stair Lights with status data

Once I settled on jumping into home automation and Home Assistant (HA), the first "practical" thing I wanted to address was the issue of lights being left on at random throughout the house. Some fixtures were greater offenders than others, but with a control mechanism like HA I could actually begin to address what others wouldn't.

Jumping into Home Assistant: The Installation (and Hiccup) Process

Screenshot of Home Assistant Initialization/Setup Screen at the user account creation step

About a month ago, I took the plunge.

After considering it for a long time and hearing about some cool stuff folks were doing with home automation, I decided it was time to start my own dabbling adventure. A warning to folks: home automation is a little bit like owning horses. There can be a bunch of expense in the process for little obvious reward.

Creating a Slack Bot for Tempest Weather Station

Image of Tempest weather station with device features highlighted

In summer 2020, I picked up a WeatherFlow Tempest station...a purchase I'd been considering for the better part of a year. It's an awesome and compact little thing, and on the whole I've been super happy with it. In my location it tends to over-report rainfall as the haptic rain sensor is also sensitive to vibrations on the mounting point (a pole in my yard).

DMARC: Moving to a Monitor-As-Necessary State

After a year-and-a-half of implementation (mostly monitoring), it is time to switch to a 'steady' or 'monitor-as-necessary state' for all of my things DMARC. I've written about this journey before, with the last major summary in November, 2021.

Upgrading an Old Application to 21st Century Passwords

I have a confession to make: I've ignored a Really Bad Password Form on an inherited web application for about at least a decade too long.

I'm not proud, but every time I considered changing the password mechanism to something more modern (and more secure), decision paralysis would set in...in great part due to the design challenges I anticipated in quietly upgrading this for users of the app in question.

The MMSMOA Retweet Bot in Action

Cartoon robot image of the @mmsmoabot with breastplate advertising MMS and the bot Twitter handle

Hot on the heels of last week's triumphant return of the "MOA" edition of MMS, I'm writing up a post-conference review of my somewhat-accidental creation: the MMSMOA Retweet Bot.

I shared the bot's story with a number of folks during the conference, often while peddling the bot's stickers, but several folks also encouraged me to share the details via blog post as well so here it is!

In-Place Upgrade of WSL Ubuntu 18.04 to 20.04

About two months back (early March to be exact), I had the opportunity to finally deprecate some old versions of applications and packages due to planned retirements and upgrades. Most specifically a full-on move to PHP 7.4 was in sight, though there were other bits. I run and have access to a bunch of different environments so it felt right to get environments back to a standard (or at least closer) base configuration.

Improving DMARC Compliance: Authenticated SMTP Relay

I've done a lot of server migrations for very unrelated reasons over the last six months or so. Many of these host applications that send emails, and I've implemented the basics to get them sending DMARC-compliant messages. This has generally been limited to DNS SPF records for each host configuration. Generally speaking, having SPF or DKIM compliance is 'enough' to get your messages not flagged as spam, though it can depend on the DMARC policy configuration.

LAMP to WAMP: Adventures in Server Migration

Server migrations are an inevitable task, but I found myself in a different than normal circumstance recently. A planned server stack retirement, combined with the server "owner's" technical capacity and expertise required a change in platform. Specifically, this shift meant moving from Linux to Windows.

Certbot on Windows: Automation Is Possible

A recent project gave me an opportunity to try out Certbot on Windows. As I've written about before, I've had an extensive journey with Certbot, at times in fairly 'non-standard' configurations, and Certbot on Windows is no different.

Moving an Old Website to Github Pages: Getting Started

Nearly 25 years ago I spun up a website featuring transcriptions of Monty Python material collected from college students in the 1980s. I don't remember how I came across the archive of these text files, but I still have the originals in part of my personal digital archive. Around the year 2000 I moved the website (and subsequently added more content) into a Wiki system (TWiki, to be exact).

Drupal Site Improvements and other Housekeeping

On the heels of (and riding the wave following) my recent migration of Drupal to a new server host, I decided it was well past time to finally address some things with my Drupal instance that were been bugging me for a long time. Of course, something like this often spirals into its own set of "other" things to fix for the greater good.

Moving a Legacy Drupal Stack to a New Server Host

One of my "end of 2021 break" projects was a planned "lift and shift" of my primary Drupal instance to a fresh, sparkly new web host stack. The stack on which it resided was reaching end of life and for a few other reasons it was time to make the change. In preparation, over the last year or so I've been de-coupling and untangling some of the baggage that had accumulated on the old server and its structure over time. Relatively simple things like straightening out, consolidating, or consistently applying vhost configurations.

Reconciling Disparate Datasets

A few weeks ago I was asked to help update a centralized inventory dataset, which to us is definitely a "tertiary" system. Several hundred device records were associated with our part of the organization, and every time I opened the list I quickly "noped" out of doing anything with it. But the time came when I needed to actually do something with it lest I wind up on someone's naughty list.

DMARC: Time to Evaluate Reports

Almost exactly a year ago, I wrote about my first foray into implementing DMARC controls. Specific to domains through which email was not intended to be sent, it was the beginning of my DMARC adventure and expansion into some 35-ish domains.

Keeping the Wireless On - Script the Reconnect

Electric arc between two plasma globes

In our classroom fleet, almost all devices are wireless-only for their network access. This as a design is great for mobility and flexibility and the user experience but presents its own set of very unique challenges on the technical side. At various times and for a wide range of reasons, we encounter the situation where devices "lose" their wireless/Wi-Fi connection. Resolution usually involves dispatching a tech to the space or walking a user through, under most circumstances, simply "reconnecting" to the proper SSID.

Breaking the Chain: An Edge Case of Let's Encrypt Root Certificate Expiration

It's been written about and announced for some time—the forthcoming expiration of the DST Root CA X3 certificate. The good news for most folks is that it's not a big deal. And that, I thought, also included me. For the most part, this has panned out to be true.

My Personal Git Cheat Sheet

I've used a number of various Git cheatsheets over the years, usually duing a moment of "how do I do __ again?" and sometimes during a moment of panic like "Shit! Undo that commit!"

Recently, I (finally) "removed my training wheels" and uninstalled the UI client I had for Git, for two reasons:

  1. I was not actually using its features anymore*; and
  2. It was constantly getting in the way of Git updates.

Git-ting the hang of Hooks

Several months ago I made the decision to finally use Git to manage a more complex "legacy" web application project that I inherited over a decade ago and continue to maintain. Years ago when migrating the web application to a new hosting stack, I ported the development/test and production sites into their own Git repositories. Thanks to the magic of GitHub, it made the actual migration to a new host pretty simple in that the migration itself (save for the database bits) was more or less a simple git clone action.

My First Twitter Bot: A Journey into Twitter's API

Dancing Robot

Sometime around Thanksgiving/November 2020, I formalized the idea that I would actually build a Twitter bot for the sake of novelty and as an experiment/learning exercise. One night at suppertime, we discussed what might be cool as a bot and those ideas are still on the list as possibilities for the future. Ultimately, I settled on a bot idea that built on some things I've used in the past (Google API) so I wouldn't have to learn All The Things in addition to building a bot and figuring out the Twitter API.

Exporting Legacy/Archival Emails with Google Apps

At work, we've had a number of folks retire over the last 18 months, and a number of those folks are holders of some significant institutional knowledge and memories.

My Incremental Certbot Panacea

I've written about Certbot more than any other topic in the last 24 months or so, in part because it's been an interesting adventure for me both in helping to demystify SSL certificates, but also because it's been an evolving and incremental process to Make It Better. The first post I'd written in February of 2019 talked about using a web service to generate a Let's Encrypt certificate...good for 90 days...for free.

Quick Tests of WQL Queries

Recently I was working on a clean-up/improvement project in the MEMCM (SCCM) console which required some WQL query work and updates. In particular, I was fiddling with some collection queries to segment some areas for a process improvement project coming up. That's intentionally vague, because the 'why' in this case doesn't really matter. What does matter is that I needed WQL to give me proper results.

Shaking The GnuCash Account Tree

Man shaking tree of money

Over the years I've developed a habit where a short part (~30 minutes on average) of most weekends are dedicated to entering the week's receipts, reconciling (or balancing) accounts, updating investment fund values, and so forth. Once familiar with GnuCash, this process is pretty straightforward and easy to do. Then, roughly quarterly, I go through and double-check any accounts that have fallen behind this cycle for various reasons (sometimes an account wasn't used during that time, other times I just forgot to reconcile it, and so forth).

GnuCash For The Win

Parks and Rec "They call me the Swiss Army accountant" gif

As I wrote about a couple months back, GnuCash is my accounting software of choice since ~2010. I wasn't exactly "sold" on it from the start, but it was a free and open-source solution that seemed robust enough to handle pretty much anything I could throw at it, from managing business finances and whatnot to a whole mess of personal accounts. Did I mention: free and open-source?

Count of AD Groups Ranked by Members

Which was the first part of my answer.

TRIM-ming up for Summer

Without going into great detail (as it doesn't matter at the end of the day), last week I encountered a vendor that apparently doesn't know how to do this very well. Or at all. What ultimately transpired is the complete failure of a reasonably-routine change process to capture a critical failure in production.

Interesting Log Entries (or, Why To Patch Thy Systems)

Random text scrolling from within a terminal window

So far in 2020, I've been keeping a closer eye on the logs of this Drupal site. Back in the day, I used to pore over logs in a sort of 'bender' fashion, presumably as I was bored or something similar. Rarely was something particularly interesting, but it was a good way to figure out and correct some random things. Still is...but it's 2020 and nobody manually looks at logs anymore.

Visual Customizations for Windows 10 in OSD

Windows logo

As we work through the tail-end of our Windows 7 fleet (January 14, 2020 is coming if you haven't heard...), I've found myself rolling a different type of hammer process for the last of the "upgrades." This past week as I was tweaking what amounts to an in-place update (by way of wipe and load) for Windows 7 to Windows 10, I was reminded of how Past Me was indeed awesome (and inspired) since this simple script with all the various background and image sizes still works in Windows 10 19XX deployments.

Dynamically Created Anchor HREFs

Multiple Arows Crossing Paths

Back in the day, namely before Javascript and jQuery were really a thing, the idea of dynamically creating an anchor's HREF attribute required some serious magic and behind-the-scenes wizardry. Or something like Flash. Those were not the days...

A Bit of Background

Several years ago, during a client's web app rebuild/refresh, I decided to clean up some of the gnarly baggage behind their reporting mechanism.

Over the years, we've had a few public Internet-connected cameras pointing at various places around campus. We've used them for publicity and other purposes since the mid-1990's, and starting in around 2010 would sometimes be called upon to create a sort of time-lapse video of activity from one of said cameras.

Windows Scheduled Tasks with Powershell

Mechanical Mathematical Calculator

As I struggled to find looked for inspiration for this week's post, I wound up looking within...oddly enough as I was reconfiguring my email out of office response (the below is what I had for my time at MMS):

MMS: Drinking From the Fire Hose

Drinking from the fire hose

I spent last week at MMSMOA, a conference I cannot recommend enough for anyone working in the Microsoft/Windows/Systems Management space. The main event, held at the Radisson Blu Mall of America, is a solid four-and-a-half days of deep technical material, networking, sharing, and more!

What's In Your Lunch Bag?

Winnie the Pooh prepares to eat

Many of those I work and associate closely with know that I'm pretty often a routine machine. I'll be writing more about the various things I've turned into simple routines, automatic processes, and so forth.

Performance Can Matter

Performance Measure

I've had this written down as a topic suggestion for some time, and to balance/counter my post a couple weeks ago regarding performance, there's absolutely another side to that coin.

Does the Performance Matter?

Does it matter?

Back around 2015 or so, I wrote a simple Powershell script which basically re-populates Active Directory (AD) group membership based on data procured from our central systems. Two primary AD groups in particular are synchronized to our print management system, PaperCut, which pre-provisions accounts and access so folks handling monetary transactions don't have to create accounts, etc.

It's Presentation Season!

Wizardry

As I mentioned a month ago, I've taken the opportunity to commit to more speaking/presentation engagements than ever before, in an attempt to better inspire folks and do more technical evangelism. It just happens to be that I have three things lined up in as many months!
