Cleaning Up Old Mistakes: Git Repos With Nested Accounts

This post is the first of a two-part miniseries identifying and correcting old mistakes. Part Deux will publish May 10.

Today's atonement for old mistakes: Git repos used in production in which nested/disparate accounts run code.

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.

* Save for the occasional git clone action

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.

Signing Git Commits: Chasing the "Verified" Stamp

I've been working on projects lately that actually involve writing more code than I have in a while...and so I'm using Git/GitHub with greater frequency than I have in some time.

Implementing DMARC: Adjusting SPF Records

It's been a couple of months since I last wrote about implementing DMARC and what comes next (review and adjustment). So I figured this would be a good time to document a few changes I've made based on the reporting data received so far.

2020: An Energy Year in Review

Now that I've had a chance to really look at the data from our 2020 electric use, in a modified format from what I've written about before, I thought I'd wrap up with an overview of our overall electric use during a most unusual year.

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. Recently I had the opportunity to work with one of these individuals as they prepared to both hand off information to others, which led me to recall several conversations I've had with my Libraries/archives friends about preserving the "right" subsets of digital messages such as email.

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.

Implementing DMARC for Active Domains: Policy & Review

This is the second post in a two-part series to implement DMARC controls for actively-used domains, where this post focuses on creating and reviewing/adjusting your DMARC policy and controls. Part one reviewed proper DMARC prerequisites and contains information you will need to have in place before creating your DMARC policy.

Implementing DMARC for Active Domains: Configuring Prerequisites

As a follow-up from my previous post about implementing DMARC controls for unused/alias domains (those not used for actively sending messages), I wanted to write a bit about how to implement basic DMARC controls for those domains actively used to send emails.

Armchair Pair Programming

This past Friday, somewhat out of the blue, I was pinged by a friend about helping him work through implementing what I'd done to date with Certbot...with the additional twist of his own unique configuration challenges.

Implementing DMARC on Alias Domains

A few weeks ago I crossed a tweet with some simple instructions for securing your "unused" email domains, specifically the few bits required to implement DMARC controls to prevent Bad Folks from using your domains to send spam emails. The short thread led to an awesome reference by the UK Government on the same process.

Automating Certbot: A Recap of My Journey

Long winding road

Over the last two months, I've shared what amounts to a four-part "series" of posts walking through my journey of using Certbot for SSL certificate management, with the primary challenge being not having the traditional root-level access on the web server. Those posts are, in order:

Certbot in Manual Mode with Script Hooks

If you've been following along in the mini series, I've gone over the details of using Certbot in manual mode, then bolting some simple scripts together to improve the process of generating and managing certs, all done with a bit of magic thanks to our old friend key authenti

Improving Manual Certbot Domain Validation

In my second post about using Certbot in manual mode, I address some of the 'pain points' from the first post: namely the process of scripting together some of the bits to create/renew a certificate and otherwise requiring fewer individual commands be entered (or remembered).

Moving to Certbot with Let's Encrypt

This is the first post in a short series of posts about automating what one can in an environment that might not support full-automation with Certbot and Let's Encrypt. Technically it's the second post as the first was geared toward setting up key authentication between systems, something that's leveraged significantly in this series.

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.

Quickly Extracting Icons with Powershell

One of the things I both love and loathe is adding the little icon to an advertised deployment in the Software Center console of SCCM/MEMCM. As many have said it in the past, "Pretty Counts" and I wholeheartedly agree.

Auto-Power On Dell Workstation

Cartoon characters join together with "Let's Power Up!" as a caption.

As we begin another academic year, this time in a pandemic, we're providing more virtual/remote desktop access to computer lab and public-access workstations for those in need. We're starting by using the machines taken out of general service due to physical distancing requirements. These workstations are still powered on, but we've removed their keyboards, mice, and fiddled with their monitor configurations (along with basic signage) indicating they are not in service (at the console/in person).

Formulas in CSV Files

Bad Magic Trick with a ladle for cooking

A while back I received a call for assistance in helping to streamline an inherited process. In this particular case, an individual had created a complex (but necessary) process to essentially transform and move data between disparate systems. The employee(s) responsible for creating this process had since left, but the process remained and needed to be manually done often enough that it was painful enough for the person now responsible for the process to ask for assistance.

Setting Up Key Authentication

Hands playing with a set of keys on a ring.

While I was preparing to write an upcoming post about moving directly to certbot from SSLForFree now that they've merged with ZeroSSL, I realized that I'd not actually ever written a post about one of the components I use all the time, including for my new certbot process: public key authentication.

Pushing Data Into Google Sheets Sheets (Yes, Multiples)

If you recall from the last tech post about pushing data directly into Google Sheets, I promised a follow-up regarding the process of adding multiple sheets worth of data to a given parent sheet.

Interesting Pandemic Electric Usage Pattern

Stock bar graph with trend arrow ending downward

This is a relatively short post, but as I entered our May electric usage into my tracking spreadsheet (see the Energy Use Analysis post from a while back), I noticed something peculiar about this last few months since the pandemic really hit (and we started staying at home all the time).

Programmatically Push Data to Google Sheets

Screenshot of a very basic CSV file of gibberish test data

I've written in the past about the ability to ship files to Google Drive via its REST API and PHP, which is a super-cool process in and of itself. In the last few months, I've been moving more and more of our internal data shipping processes to Google Shared Drives for ease of end user access. As folks started working remotely, moving data to Google has solved several support burdens regarding access and such.

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).

Simple, Yet Powerful Excel/Sheets Functions

Cartoon about functional programming

As a reflection exercise for a project I wrapped up a bit ago, combined as an exercise to make Future Me's life a Better Place, I pulled together a simple Google Sheets workbook to make a quick 'calculator' and balancing mechanism to help keep track of a couple datasets. And in so doing, I again befriended a couple of super simple, and super powerful functions:

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

A cartoon/drawn group of random people

A week ago, someone on one of our more generalized Slack channels asked if anyone knew how to make AD Users and Computers (ADUC) filter mechanism rank output based on a group membership count. Now, I don't necessarily understand (or honestly, care) about the particular use case, but I knew the answer was going to be 'no, that can't be done by way of the GUI.' Which was the first part of my answer.

TRIM-ming up for Summer

Trimming a hedge with lawnmower attached to tractor loader

Not really TRIM-ming for summer, but taking the opportunity to briefly write about Rule #1 when dealing with unknown (or incoming) data.

Sanitize. Thy. Inputs.

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.

The Financial Automation Account

Mechanical slide coin sorting machine

A couple weeks ago, I made brief mention of my financial automation account and how I've come to consider it my "free money" account. I wanted to dig into that topic just a bit more, since it's become a key component of my own regular financial well-being.

Why an Automation Account?

Simple: it's thoughtless, once set up.

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...

Capturing Your Internet-Connected Webcam Images

Puppet bird with binoculars

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.

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!

Performance Can Matter

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!
