Cheap, Loved and Sharp(er) | Putting an Edge on a $1.00 Hatchet

Earlier this week I found myself scrounging through drawers looking for a tool to pry a plastic disk from the glue pad it was cemented to. I found just the tool in my Columbia Must-Have Multi-Tool. Between the heat from the hairdryer and the leverage from the multi-tool, I had the project completed in no time.

I also got to relish in the joy my Columbia Must-Have Multi-Tool gives me.

Back in 2016 Shira and I visited Bogota, Columbia. While there we found ourselves in the equivalent of $1.00 store, and while shopping I spied a bin full of these beauties:

Did I need a poorly made combination hammer, pry-bar, hatchet, nail puller? Uh, yeah. I did. Badly. The 10 year old boy in me needed one, and the adult in me figured it would be a novel souvenir.

Back from our travels, I hadn't found a use for the multi-tool. One reason why: the hatchet blade was comically dull.

After my experience earlier this week using the pry-bar, I got to thinking that sharpening the blade may be a worthwhile undertaking. I'd end up with a more useful tool and perhaps learn something along the way.

I followed the advice offered in Home Built Workshop's How to Sharpen an Axe video. I ordered an $8.00 axe file off of Amazon, clamped the multi-tool to our kitchen island, and cautiously started to scrape away at the blade.

It was like magic! With just a few strokes of the file I could tell that I was removing metal, shaping the blade and generally making things better. It's almost like the axe file is designed for sharpening axes (spoiler alert: uh, yeah. What else would it do?). I suppose I figured that the file required a skilled operator; apparently not.

All told, I probably spent 30 minutes sharpening both sides of the blade. I found the repetitive process oddly soothing. I'm the farthest thing from an expert, but I'm almost certain I could feel when the file was at the right angle and I was making forward progress.

The blade is definitely not 'shaving sharp.' But it's vastly sharper than when I started. As you can see from the carrot I sacrificed to the cause, not only could I chop, but I could slice shavings, too. I do believe I finally have a functional blade on this sucker.

Overall, I'm really pleased with this little project. I avoided buying gimmicky or over-priced products to get the job done. Instead, I focused on learning a new skill in a low-pressure way. I couldn't have dulled the hatchet any further. About the worst I could done would have been to ruin an $8.00 file. That's a risk I was glad to take.

Want your own Columbia Must-Have Multi-Tool? You can buy the same tool on Amazon for $12.00. It's not the $1.00 or so I paid for mine in Columbia, but of course, you won't have to buy plane tickets to Bogata. So there's that.

The hatchet even comes with this notice: comes dull for your own safety, sharpen it to your own preference. You see, the dullness is a feature, not a bug! And I think they're on to something: buying a cheap hatchet and file will give you a chance to be amazed at what a little elbow grease can produce.

Four Photos, Four Truths

 

I captured the above photos by running by the same set of trees for 4 weeks. Here's four take-aways from this experiment.

1. Trees are Amazing

They take whatever abuse nature and humans throw at them during the winter, and just when you think they can't possibly be alive, they explode with growth. I know this is how trees work, but still, it's amazing.

2. Unix is Great

I had dozens of the photos of the above scene, yet I needed to pick the best four photos to work with. After downloading a zip file of all images, I ran the following Unix commands to organize them:

# Make a directory for each day and store all the day's photos
# in it
$ for f in *.jpg; do d=$(identify -verbose $f  | \
                         grep exif:DateTime: | \
                         awk '{print $2}' | \
                         sed 's/:/-/g'); \
    mkdir -p $d ;  \
    mv -v $f $d; \
done
renamed '20210311_165836.jpg' -> '2021:03:11/20210311_165836.jpg'
renamed '20210311_165840.jpg' -> '2021:03:11/20210311_165840.jpg'
renamed '20210311_165842.jpg' -> '2021:03:11/20210311_165842.jpg'
renamed '20210316_165538.jpg' -> '2021:03:16/20210316_165538.jpg'
...

# Launch the feh image viewer to preview each
# directory's images at once
for d in *; do (cd $d ; feh --auto-rotate -i  -E 300 -y 300  *.jpg &) ; done

Using feh I was able to get a visual overview and then pick the four best matching photos.

3. Art is Hard

In my mind's eye, this project was going to result in a composite image that displayed the breathtaking transition from lifeless landscape to Cherry Blossom Greatness that the DC area is known for.

Needless to say, I missed that mark:

You can see the transition in the above photos, but there's nothing jaw dropping about it. My attempt to capture the scene precisely the same way every week was a bust, and many of the trees around where I took these photos were bursting with flowers while the trees I focused on where relatively bare.

Ultimately, I got out of this project what I put it into. I grabbed photos while out on my run, and the results look like this.

All this makes me appreciate a well crafted art project, the likes of which takes notable time and attention. And if you do it right, folks will almost certainly think I could have done that.

4.The App I Needed

To do this project right, at a minimum I'd need more care in picking my location, more time to allow shooting multiple locations, and the use of instruments (measuring tape, compass and tripod) to confirm consistent camera placement.

However, I could have shortcut this a bit if I had a camera app that supported Onion Skinning. That is, the ability to show a partially-transparent imagine in the camera preview. This allows lining up a shot using a guide-photo.

A quick search on Google Play returned a couple of options for a camera app like this, though none of them looked like a fit for me. Ionic, my app building framework of choice, has a Camera Preview plugin. An interesting test would be to place a partially transparent image over the Image Preview component. If that works, then I could make my own 'Onion Skinning Camera App' with relative ease.

Review: A Minute to Midnight

Every once in a while Shira will be reading a book she thinks we might both enjoy, and she'll opt to read it aloud. I enjoy audio books, so I find this quite the treat. It turns reading into a shared activity, like binging a TV series. Unlike TV, we can do this while multi-tasking.

So for the last few weeks, while I loaded and unloaded the dishwasher or was cleaning the kitchen for Passover, Shira narrated David Baldacci's A Minute to Midnight.

In A Minute to Midnight I got to meet Atlee Pine, the hero of the book. I like her. Mostly. She's thoughtful and confident, without being insufferable and cocky. I can't tell if her weight lifting past adds detail to her character, or puts her over the top.

The pace of the book felt slow, but if I'm kind, I can chalk that up to Baldacci trying to keep things realistic. She encounters a series of puzzling murders, and I can appreciate that it takes time to put all the pieces together.

One aspect of the book I found surprisingly enjoyable was how Baldacci had a number of plot details that initially seemed like author goofs, but upon further reflection made sense.

Take Pine's childhood. Are we to believe that a trained FBI agent wouldn't spot the massive inconsistencies in her own parent's behavior? She can tell when a stranger is lying to her, but doesn't recognize the suspicious behavior in her own parents?

Actually, I buy that. For must of us, whatever our childhood was, was by definition normal. We can't imagine our parents as inexperienced human beings with their own baggage because to us they are Mom and Dad, not real people.

Or consider the presence of the Pagani. Are we to believe that a baddy would opt to be seen in a 20 million dollar car in a resident neighborhood? That's ridiculous. But when we consider the role of the car was to attract attention and that the person who selected the car didn't know the details of what they were picking, the choice seems plausible. Who would have thought the flashiest car in the garage would turn out to be absurdly unique?

One quirk of the book I haven't decoded: its title. I missed the first chapter (Shira started reading the book to herself before she made it an audio book), so maybe the answer was in there. But honestly, I have no idea what the title is referring to. I guess I'll have to hit Google to find out.

Should you drop everything and read A Minute To Midnight? Sadly, no. It's a fine read if you like a good o'l murder mystery, but there wasn't anything here to make it stand out for me. The story was generally slow and snapped into place at the last moment in typical fashion.

Still, as a shared reading experience, it was a positive one. And we will definitely be back for the next book in the series.

Two Tuna Based Observations

Two observations on this fine Monday morning:

First, what a world we live in! You're telling me that I can order 48 packets of tuna on Sunday night at 8pm, and they're delivered to my front door by 9am the next day? In time for second breakfast, no less! And, all this convenience for a price that's cheaper than buying at the supermarket?

Amazing.

And second, while we've never had an issue with our packages being stolen, and I'd never condone the practice, I can say that an itty-bitty-teensy-weensy part of me wishes that a porch pirate had nicked this one. They'd pick it up and think, hmmm, this has some heft to it I bet it's pricey electronics.

And when they opened the goods they'd be shocked to find they just stole some freak's tuna stash. Oh the very thought of the hypothetical look on their face makes me smile.

Tuna, anyone? I've got more than enough to share.

Build Your Own LG V60 Floating Bar

Shira's new LG V60 ThinQ is a sweet phone. The jury is out on whether the dual screen is genius or gimmick, but I applaud LG for the attempt. As someone who regularly busts out a bluetooth keyboard to program directly on my phone, all that screen real estate is a dream.

The Challenge

One feature that Shira misses with her new phone is the LG Floating Bar. This compact menu bar could be expanded to quickly access apps or contacts. For a while, there was a recipe for running an old version of the Floating Bar on the V60, but recently that stopped working.

Knowing her husband has mad next level programming skills (my words, not hers), she asked if I could help build her an alternative app. A quick Tasker search encouraged me that I could.

My search turned up a video I'd watched years ago, but had forgotten about. Floating Bar Demo: Auto Tools Web Screens:

So this was possible. It took me a couple of attempts, however, to figure out how to build and customize my own floating bar. I'd like to save you the trouble of figuring this out yourself, so here's a quick tutorial to get you started. Enjoy!

Step 1: Install The Tools

To make your own bar you'll need Tasker, AutoApps and AutoTools. These apps are worth paying for, so do so if you can.

Step 2: Install the Demo Floating Bar

Fire up tasker and make a new Task called FloatingBar Launcher. Add a single action: Plugins » AutoTools » Web Screen. Configure the action, selecting 'Screen Preset' and choosing 'Floating Bar.' Click the check-mark to save your work.

If all goes well, you'll find yourself back at the task definition. Run the task and you should see a floating bar appear at the top of the screen. Awesome, right?

Step 3: Try, Fail and Fix the Gravity Setting

Let's say you want the Floating Bar to appear on the right hand side of the screen versus the top. It's easy enough to edit the action you created, going to Window Settings » Gravity » Right.

Save your work and re-run the Task. If all goes as expected, then you'll notice nothing happened. You changed the gravity, but the toolbar still shows itself at the top of the screen. What gives?

What seems to be going on is that the first time you ran the task you launched your floating bar. The floating bar is still running, so when you executed the task again, no new floating bar was created. My fix, therefore, is to insert a new action into the task that closes the floating bar. This forces every execution of FloatingBar Launcher to create a fresh floating bar and use whatever settings have been selected.

Create a new action: Plugin » AutoTools » Web Screen. Configure the action and select Display Mode » Close. Yes, to close a web screen you have to make a new web screen. Just go with it. Make sure this closing action is first in the list of actions to execute and then try running the Task. If all goes well, you'll have a floating bar that respects your choice of right-side positioning.

Obviously, you'll need to use this close action with care. As it's setup above, it closes all web screens. Ultimately, you'll want to tweak it so that it just closes the one floating bar you're creating, otherwise this will mess with your other Web Screen creations; probably not what you want.

Step 4: Make It Your Own

You've now got a floating bar that you can control. The next mystery is how to replace the stock icons with your own. Turns out, that's easy. Edit the Configuration of the Floating Bar Web Screen and go to Items. Here you'll configure key aspects of your floating bar. Start by selecting the icons you want to include. AutoTools will help you out by letting you graphically select them.

Next, click on the 'Commands' field. This brings up a text box that you need to fill in with care. You want to enter a comma separated list of words here, where each word will correspond to the icon you selected. Given the icons I've chosen, I entered the following:

  Lamp,House,Clock,Calc

It's important that there are no spaces after the commas and that capitalization is consistent. Finally, I filled in the Command Prefix with FloatingBar

When I re-run the FloatingBar Launcher Task I now see a floating bar with my selected icons on it. When I click the icons I see a message showing me the word I put in the Command list prefixed by the Command Prefix. Sweet, right?

Step 5: Make It Work

We've customized our toolbar so that it shows the icons we want and generates the commands we want. Now how do we respond to those commands? Easy. Make a new Profile: Event » Plugin » AutoApps. Notice here we selected 'AutoApps' when creating the profile, not AutoTools. This wasn't obvious to me, but this is what you're after.

Configure the plugin by entering a command that your floating bar generates, for example: FloatingBar=:=Calc.

I'm going to continue with the theme of building out 'FloatingBar=:=Calc', so I created a new Task named 'FloatingBar Calc'. That task has a single Action: App » Launch App » RPN Calc.

With that profile enabled, when I click on the calculator icon in the toolbar the RPN Calc app is launched. The floating bar works!

Step 6: Make it Awesome

At this point, you should have a functional floating bar. You need to make corresponding actions for every command, and you'll want to tweak the floating bar so it looks good. Take time to browse through the AutoTools Web Screens options and customize away.

Insights from Passover, 2021 Edition

Passover 2021 is on! We're still in pandemic mode over here, so our seders were small and I attended services over Zoom. Still, I've picked up a number of new insights this year which I'm always eager to share.

A huge thanks to my Mother-in-Law for getting me a copy of The Szyk Haggadah. The graphics are both gorgeous and profound, and the commentary is terrifically insightful. I can't recommend it highly enough. You'll see below that this text is responsible for a number of fresh insights this year.

D'Za"Kh, 'ADa"Sh, Be'aCha"V

On the first day of services I posed a question we've had at past seders but kept forgetting to research. Why does the Hagadah include Rabbi Yehudah's ten letter abbreviation for the plagues?

A number of members, including Andy and Fred, suggested that the abbreviation was there for the same reason why my math teacher had me learn Please Excuse My Dear Aunt Sally; it's a useful device for remembering a sequence. In their eyes, as an educational aid it needs no additional explanation for its inclusion.

Rav Natan added that the Rabbis of the Talmud often liked to create mnemonics. In a section of the Haggadah where we just finished doing textual analysis (linking verses from Deuteronomy 26 to the entire Passover story), it makes sense that the Rabbis would add another favorite move of theirs, a mnemonic. In other words, we're in 'Talmud Mode,' and the Haggadah fully embraces this.

Others, like myself have looked for deeper meaning. Eliezer Segal compiled a number of these hypothesis including the the possibility that the gematria or letter grouping of Rabbi Yahudah's abbreviation has meaning.

Another explanation: there's a midrash that suggests the plagues were written on Moses' staff. Rashi neatly proposes that it was Rabbi Yehuda's abbreviation that was written there. This solution is both mystical and practical!

Finally, I can glimpse a sort of political reasoning for this inclusion as well. We take the 10 plagues for granted, though they aren't clearly enumerated in the Torah this way. Things get even more complicated when you consider Psalms 78 and 105 have different listings of plagues. Perhaps Rabbi Yehuda's inclusion is yet another attempt to cement the 10 plagues as the Haggadah has them noted.

Drops of Wine

Also at our services the discussion of spilling out wine at each of the plagues came up. There was near universal agreement that one had to be careful with the spilled wine, as surely that wine had been compromised due to being associated with plagues. It was funny to hear the jocular warning about having to avoid licking the finger you dipped into the wine glass from others, as I thought that was something only our family joked about.

Thanks to the Syzk Haggadah I learned two new variations on this tradition. The first is that some Jews spilled out wine at each of the plagues to appease the evil eye. What better way to keep your seder running smoothly than to take a moment and get the evil eye a bit drunk?

Another, more serious observation is that Szyk avoids all mention of the pouring out of wine during the recitation of the plagues. It's not clear why this is. One possibility is that given the political climate he found himself in (think Europe, 1930's) he was in no mood to embrace the custom of pouring out wine as a sign of sympathizing with the Egyptians. To Szyk, his enemies deserved the justice they had coming; there was no need for an extra serving of empathy.

On B'nai Brak

The commentary on the Syzk Haggadah suggests that the B'nai Brak seder paragraph is more than a cute story proving the point that all who are wise should continue to recite the Passover story. It suggests that this description is there to add weight to the new type of seder that Jews were supposed to embrace: one that wasn't dependent on the Temple and Pascal Sacrifice.

While a seder spent noshing and talking is familiar to us, to our ancestors it would have seen woefully incomplete, or at the very the least a dramatic change.

This explanation makes even more sense to me during the Covid-19 Pandemic. Suddenly we find ourselves having to alter our Passover practices. It's no longer families smooshed together around a table loudly arguing; or reciting Hallel in shul with devoted regulars. It's a quiet Seder evening and services over Zoom in my basement. There's still Hallel, but I'm on mute and only the leader can be heard.

While Passover may be different, it's not gone. If the Rabbis at B'nai Brak can find meaning in their new arrangement, so can we.

The Other Wicked Son

After the Four Sons we read a paragraph that talks about the timing of the seder:

It could be from Rosh Chodesh [that one would have to discuss the Exodus. However] we learn [otherwise, since] it is stated, "on that day." If it is [written] "on that day," it could be from while it is still day [before the night of the fifteenth of Nissan. However] we learn [otherwise, since] it is stated, "for the sake of this." I didn't say 'for the sake of this' except [that it be observed] when [this] matsa and maror are resting in front of you [meaning, on the night of the fifteenth].

I appreciate how this fits the theme set earlier in Haggadah with with the B'nai Brak story and the paragraph that follows it. It's teaching us that what we are doing is Kosher even though it may vary from what the Torah or Temple practices prescribed.

But why put this paragraph describing the timing of the seder after the Four Sons? Why not group it with the other paragraphs closer to the start of the seder?

Perhaps I was just in a feisty mood this year, but if I squint I can see this paragraph's placement as intentional. We imagine four personalities sitting around the table and the answers we wish to give them. I can see how this paragraph on timing speaks to a fifth personality.

This fifth 'son' I imagine is a mash-up of the wicked and wise sons. Like the Rasha he's up to no good, but he's got the wisdom of the Hacham to try to derail the seder from the inside. Why are we even here tonight? He or she offers up. The Torah tell us that we should tell the story on Rosh Chodesh. That's the first day of the month and today is the 14th. Y'all are 13 days late on your seder!

This individual has come to the table with 'proof' that his fellow seder participants are all wrong.

The Haggadah is unfazed; it has points and counter-points at the ready.

Perhaps I'm being too harsh here. Maybe this mixture of Wicked and Wise is a good thing. Perhaps the Haggadah is sending us a message that asking sharp questions is exactly what we should be doing, and that's why this answer on timing is so verbose. Don't avoid thorny questions it seems to be saying, lean in and ask away!

Art on the Run

One of my favorite pieces of art is Ripple by Tejo Remy and Rene Veenhuizen. You won't need to make an appointment at a gallery to see this piece as it's bolted to the outside of Arlington County's Water Treatment plant. You need only stroll along a delightful trail to take in its 800 feet of social commentary.

I enjoy Ripple for a number of reasons. It's creatively placed and has a well camouflaged meaning. I've come to appreciate that what looks like kids detritus is actually a novel statement on unexpected consequences, ripples if you will, of our behavior. And I get to ponder all this while jogging by.

Given my affinity for seemingly random acts of art, you can appreciate my joy of when I was running the Four Mile Run Wetlands Trail (not far from Ripple) and came across what seemed to be a painted stack of rocks. It wasn't immediately obvious what I was looking at: something discarded, a one off art project? As I ran further on, I saw another stack of painted rocks. Now I had to stop and take some pics. Check it out:

So what I did discover? It seems the Alexandria Commision on the Arts has sponsored three recent art installations. One of them is by Alexander Rudd. And on Alex's Instagram page are these pics:

Those are the sculptures I saw on the trail. In Alex's feed they were in the back of a moving truck.

As for more details, the article describing the art installations says only: "the Alexandria Commission on the Arts did not release information on the nature of those projects."

We got a good 'ol fashion public art puzzle to decode.

I don't think Alex is going to give us much in the way of hints. His 'gram bio reads:

Conceptual read vs arbitrary appearance + algorithmic disposability = objectivity confusion

Yeah, that clears everything up.

Still, challenge-excepted. I'll have to add Four Mile Run to my upcoming running routes to get some more viewing time in.

Caption Me: Divorced Birds Edition

I caught this scene on my run yesterday:

While I'm not sure of the caption yet, these pics do feel worthy of the r/DivorcedBirds treatment. And what is DivorcedBirds you ask? Reddit explains:

For pictures of fabulous fowl who look like serial monogamists. Please post pictures of birds who look like they are twice divorced (or more!) Pictures/Videos must be of actual birds (feathered fowl), not human women, not art or paintings or photoshopped. No dead birds.

In truth, that description doesn't do the sub-reddit justice. Divorced Birds is an exercise in (very) short story writing with the theme of, well, divorce. It captures so many emotions: anger, hope, envy, shame and more with just a pithy headline and follow-up comments. It ranges from unbelievably wholesome to downright wicked. Here's an example that's currently on the home page:

So, what's the deal with the above birds? Leave your divorce, or not, related captions as a comment.

Who's reading what? Tracking User Interaction in WordPress's Arconix FAQ Plugin

I added a FAQ to my website and found myself with a new question: what FAQs were people actually reading? I'm using the WordPress Arconix FAQ plugin which let me easily author and display questions and answers, but doesn't appear to track usage.

My solution: push an event to Google Analytics every time a user expands a FAQ. Google Analytics does the heavy lifting, as it will store and report on event activity. All I have to do is to convince WordPress to send the event when the user clicks on a question. Here's how I did that.

Step 1: Add Event Tracking to my Theme

In my theme's functions.php I added the following code:

add_action('wp_enqueue_scripts', function() {
  wp_enqueue_script('theme-analytics',
                    get_template_directory_uri() . "/js/analytics.js",
                    ['jquery'],
                    md5_file(__DIR__ . "/js/analytics.js"));
});

This loads js/analytics.js when my theme loads, and forces the browser to pick up changes when I modify analytics.js. I've made analytics.js depend on jquery. This simplifies the code that will be found in analytics.js.

Step 2: Add The Event Tracking Code

Inside of js/analytics.js I added the following code:

jQuery(document).ready(function($) {
  var MEASUREMENT_ID = 'UA-XXXXXXXXXX-1';

  function sendEvent(action, category, label) {
    console.log("GA Event", action, category, label);
    
    gtag('event', action, {
      event_category: category,
      event_label: label,
      value: 1,
      send_to: MEASUREMENT_ID
    });  
  }

  $(document).on('click', '.arconix-faq-title', function() {
    var me = this;
    setTimeout(function() {
      var expanded = $(me).hasClass('faq-open');

      if(expanded) {
        sendEvent('show', 'faq', $(me).text());
      }
    }, 100);
  });

});

You'll want to be sure you update the value of MEASUREMENT_ID so that it contains your analytics property identifier.

I'm monitoring clicks on the CSS class .arconix-faq-title. I added a 100 millisecond delay because I'm not confident of the timing of things. I want to check if the FAQ is expanded, the time delay insures that when I do this check the UI code will have already run.

With these bits of code in place I can now check out FAQ activity in Google Analyics:

If I drill down into Event Category and set the Event Label as the secondary dimension I'm able to see the questions that get the most traction.

But Wait, There's More!

Now that I've gotten the hang of sending events, I couldn't stop at just tracking the FAQ page. I added this code to analytics.js to track Contact Form 7 submissions. In this case, I'm using the subject of the e-mail as the event label:

  $(document).on('wpcf7submit', function() {
    var subject = event.detail.formData.get('your-subject');

    sendEvent('submit', 'contact-us', subject);
  });

My company's home page includes a call to action button and a mini FAQ. I added events to track their interaction as well:

$(document).on('click', '.q-and-a-grid .entry', function() {
    var q = $(this).find('.question').text();
    sendEvent('click', 'home-faq', q);
  });


  $('a[href="#content-start"]').click(function() {
    sendEvent('click', 'home-button', 'learn-more');
    return true;
  });

You've Got To Have Goals

Along with viewing these events within Google Analytics, it's possible to set these up as goals. For example, here's the goal definition for my FAQ page:

One interesting use for goals is to power experiments within Google Optimize. For example, you could run A/B tests on different wording for a question, and have Google pick the one that's read most frequently.

On This Day, Blogger Edition

I recently built On This Day: Google Photos Edition. This tiny web app shows you photos you took on the current date going back 15 years. I built it originally for finding Zoom Backgrounds, but found it to be a suprising source of inspiration and entertainment.

I've been publishing this blog for almost 16 years. I've often struggled with maintaining past posts. Services (I'm looking at you, Google Picasa!) and technologies (and you, Flash!) have come and gone over the years, leaving some posts pathetically broken.

If had a tool like On This Day: Pics, that let me see what blog posts I created on this date, I could review and edit these posts. If I made this a daily habit, I could slowly work my way through my 6,500+ posts without breaking a sweat.

I give you: On This Day: Posts edition, a quick web app that dumps out the posts you authored on this day.

I see that most of the posts from today are still looking good. The video I shot of Shira driving in Australia back in 2009 still works, and the pics from our first day traveling in Singapore are also there.

I did find, however, that write-only a tool I made to experiment with append only writing was broken. After a few minutes of JavaScript debugging, it was back to working.

There's still a need for tools to help maintain my blog. The labels, for example, are a mess and a bulk-label-fixing tool has been on my radar for years. But this day by day, spot-check-and-fix approach seems to hold real promise.

You've got Questions. I've got Answers. Finally.

If you have an online business, it's a no-brainer to offer a FAQ section on your website. And yet, for years, my website went without this basic page. I'd always been too busy, or had some other execuse, to put it together.

But no more! I finally forced myself to focus on this, and a few hours later the Ideas2Executables FAQs page was born. I've never been so excited over a list of questions and answers before.

Can you think of any business or software development questions you'd like answered that didn't make the list? I'm a question-answering beast now!

You Need This Information | What to do in a Power Line Emergency

If you're think I'm blogging about power line safety as part of my disaster planning kick, I applaud your attentiveness. But no, this post is all thanks to the goofy sub-Reddit /r/ThatLookedExpensive.

Here's the Reddit post that inspired this PSA. It features a dump truck that makes contact with power lines and disaster strikes from there. The comments on the post talk about what actions you can safely take if you find yourself in this situation. Ultimately, someone linked to this dramatization offered by Puget Sound Energy.

As I watched this video, I thought to myself: how do I not know this information? This feels like information that I should know.

So yeah, because you live and drive near power lines, you need to know this information too. Take 5 minutes and watch the video.

On This Day, Google Photos Edition

A First World Problem

With so many meetings and events being held on Zoom I found I had a new first world problem: what photo should I select for my background?

After a bit of experimentation I arrived at a solution: I'd look at    photos that I taken on the current date going back a few years, and pick from one of those.

While I did this to help narrow the photos to pick from, it had surprising side effects. I found it instructive and inspirational to look back through the years and see where I was traveling and what projects I was working on. Picking a background became a useful little exercise in itself.

The Manual Solution

Convincing Google Photos to show photos taken on a particular day took a bit of experimentation. I found what works best is to search for date spelled out and quoted like so: "March 10, 2010". Yes, the quotes are necessary. Attempts use other formats didn't work reliably.

The Automated Solution

Naturally, I got tired of searching by hand. So I made an app for that. I give you: https://code.benjisimon.com/on-this-day/.

This little web app is slow and buggy. Most of the coding effort was spent getting OAuth2 authentication to work, and even then it's struggling with token-refreshing. I also spent more time than I'd like to admit puzzling out how to call the searchMediaItems method on the PhotosLibraryClient. Ultimately, I figured out how to get it to accept the specific date and result size I was targeting.

Still, as rough as the app is, it meets the need. I can now visit the on-this-day, and after a few moments, I see photos I took going back to 2010.

I'm now using this to set my desktop background on a daily basis. I'm telling you, this little walk down memory lane is surprisingly enlightening.

Check out the code for on-this-day over at github. If you're looking for OAuth and Google Photo PHP API SDK examples, this code may be instructive. Or maybe it's a cautionary tale. Either way, I hope you find the code and site useful.

Review: The Unthinkable: Who Survives When Disaster Strikes - and Why

I finished The Unthinkable: Who Survives When Disaster Strikes - and Why by Amanda Ripley and couldn't help but feel overwhelmed. She covers so many disasters from some many different perspectives, that by the end of the text I was maxxed out.

I'm sure that wasn't her intention, but the comprehensive nature of of the book struck me as a disadvantage. Ripley's a journalist, not guru, so her mission is to share what survivors and experts have to say about their experiences, not tout her own philosophy. This leads to advice that naturally contradict each other.

Consider this example: first, to reduce information overload focus on disasters that are likely to happen. Ignore the media hype. You're more likely to be injured in a car accident, then be involved in an active shooter incident, so focus on steps you can take to increase your safety on the road.

However, a second tenet of the book is that it's precisely the outlier events, the unthinkable ones if you will, that leave you open to catastrophic handling because they so unfamiliar. So it's not likely that you will end up in an active shooter incident, but if you do and you've done no preparation, chances are you'll react poorly.

In short, by the end of the text, I didn't anymore anecdotes or experts; I just wanted to be told what to do!

After some reflection, however, I've come to appreciate The Unthinkable's approach. Yes, it's goal of being comprehensive can be daunting, but it also elucidates a novel strategy. To me, it goes like this:

During an emergency, a person travels through three stages: denial, deliberation and the decisive moment. Ideally, you'd zip through denial, have quick and intelligent deliberations and execute the best actions available to you during the decisive moment. Through Ripley's research, we appreciate that there's no way to guarantee an optimial traverse through these stages. Even your everday temperment isn't a strong indicator of how you'll perform.

But, there is good news: through small changes, you can improve your performance in a disaster. Take the active shooter scenario above. If you complete Run / Hide / Fight Training, get into the habit of noticing exits when you walk into buildings, practice leaving through different routes at your work place and keep a trauma kit at your desk, you'll be in a far better position to survive an active shooter. You'll also be in a better position to deal with a fire, earthquake or coutless other disasters that call for evacuation and the possiblity of mass casualties.

Using this approach, I can imagine a simple disaster optimization algorithm: identify risks, look for simple yet effective ways to mitigate these risks and put these discoveries into practice. And repeat.

So yes, Unthinkable is daunting. But in this context it's also uplifting. You don't need to spend huge amounts of money or re-work your entire life to be disaster ready. What you do is need is imagination, creativity and perseverance. As disaster after disaster shows in Ripley's book, small changes can have a mighty impact.

Yum! Greens n Teff, Vegan Ethiopian Goodness

We tried Greens N Teff last night for the first time, and it was an all around fantastic experience. GnT is a purely vegan Ethiopian place that opened down the street from us. Considering how much we like Ethiopian food and how rare fully vegetarian restaruants are in the area, this is a bit like winning the lottery.

On paper the place seemed great, but we tried to temper our expectations.

While on a walk in the warm'ish weather yesterday we placed an order and 25 minutes later dropped by to pick it up. GnT is tucked away in a tired looking part of the Pike. What we found when walked in delighted us: a spotless location with a warm couple who welcomed us and had our food ready. I asked about Minchet, a dish that was available to order but didn't have a description on the menu. Their response: here, try a sample. It was tasty, perhaps we'll get it next time.

Once home, we chowed down on our order. The Mushroom Tibs was probably the winner for the tastiest dish, though they were all solid.

There hasn't been a whole lot of great resterauant news for us during the pandemic. Heck, we lost our donut shop at the end of last year. But a vegan restaurant walking distance from our home? What more could we ask for?

Between GnT and Dama (also on Columbia Pike), we're more than covered for all our Ethiopian food needs.

Update: Apparently we aren't the only ones who are impressed with Greens N Teff. Arlnow reports that the community in general is a fan.

Using 1password To Seamlessly Manage Subversion Credentials

Subversion Authentication is Painful. Let's Fix That.

Subversion authentication is a pain. For years, I got by on plain text storage, but that's insecure and deprecated. On some platforms, like Mac OS, it's possible to use the system keychain to manage access. However, this becomes both a source of inconsistency and frustration as I work across multiple devices and operating systems.

What I wanted was to have subversion pull my credentials out of 1password. But how would I even begin to add this support to subversion?

Inspired by the 1password command line tool and this recipe for managing ssh keys in 1password, I found a way. This post is my attempt to document that process.

Assemble the Pieces

Convincing subversion to use 1password for authentication requires three properly configured components. If any of the three tools isn't setup right, the chain fails and authentication is a no go. Let's go through this step by step.

Tool 1: op

The op command line tool gives you shell script access to 1password. Make sure you can sign in and pull down the password for the relevant subversion accounts. Here's how that may look:

# The First Time
$ op signin allmysecrets.1password.com contact.ben.simon@gmail.com

# After the account is setup
$ eval $(op signin allmysecrets)

# Print the password for your subversion account.
$ op get item 'master svn account' | \
  jq -r '.details.fields[] | select(.designation=="password").value'

Tool 2: gpg-agent

gpg-agent is the glue that holds our solution together. Subversion, as we'll see in a moment, can be convinced to consult gpg-agent for credentials. Using gpg-agent's ability to preset a passphrase, it's possible to programmatically insert credentials into gpg-agent. To configure this, make sure your gpg-agent config file, ~/.gnupg/gpg-agent.conf, has the following settings:

allow-loopback-pinentry
allow-preset-passphrase
default-cache-ttl 34560000
max-cache-ttl 34560000

The allow-preset-passphrase setting is key. It's what allows gpg-agent to accept passphrases from an external source like 1password. The high values for default-cache-ttl and max-cache-ttl ensure that once I store credentials in gpg-agent they won't time out. This is personal preference, and if you wished, you could lower this value.

Having a properly configured gpg-agent gets you most of the way there. The last challenge to setting up gpg-agent is finding the location of the gpg-preset-passphrase command on your system. In every version of Linux I use, I find it's in a different location. For example, I'm composing this blog post on a Windows Subsystem for Linux Ubuntu instance, and gpg-preset-passphrase is found in /usr/lib/gnupg/.

With the config setup and gpg-preset-passphrase found, it's time to try this out.

# Confirming our test creds aren't there.
$ echo "GET_PASSPHRASE --no-ask --data passphrasetest1 a b c" | gpg-connect-agent
ERR 67108922 No data <GPG Agent>
  
# Store the credentials
$ /usr/lib/gnupg/gpg-preset-passphrase -c -P "ShhhItsASecret" passphrasetest1  

# Confirm they are stored
$ echo "GET_PASSPHRASE --no-ask --data passphrasetest1 a b c" | gpg-connect-agent
D ShhhItsASecret
OK

Tool 3: subversion

First off, your version of subversion needs to be built with gpg-agent support. Check this by running svn --version:

$ svn --version
svn, version 1.13.0 (r1867053)
   compiled Mar 24 2020, 12:33:36 on x86_64-pc-linux-gnu
...
The following authentication credential caches are available:

* Gnome Keyring
* GPG-Agent
* KWallet (KDE)

If GPG-Agent isn't listed under available authentication credential caches then you need to build or download a version of subversion that does have this support. It'll be worth it, I promise.

Next, update ~/.subversion/config so that it uses the gpg-agent authentication cache:

### Section for authentication and authorization customizations.
[auth]
### Set password stores used by Subversion. They should be
### delimited by spaces or commas. The order of values determines
...
# password-stores = gpg-agent,gnome-keyring,kwallet
### To disable all password stores, use an empty list:
password-store = gpg-agent

Next, perform an operation that requires subversion authentication, like say 'svn up.' If all goes well, svn should prompt you for your password by using your system's gpg-agent pin-entry program. You can cancel out of this.

Finally, determine a number of important details with how subversion is interacting with gpg-agent. Do this by looking in the subversion auth directory, ~/.subversion/auth/svn.simple/. You should see files named like so:

$ cd ~/.subversion/auth/svn.simple
$ ls -1
3f08d77847ea42f0b7b1ccd66fd14138
a7c22b9f8eabdc93df040f5954967d2b
7f0a2d6c2e00dc758c9385fe821f07cb

There should be one file for each subversion domain that you access. Peeking inside one of these files should show you something like the following:

$ cat 3f08d77847ea42f0b7b1ccd66fd14138
K 8
passtype
V 9
gpg-agent
K 15
svn:realmstring
V 39
<https://master.securerepo.com:443> SVN
K 8
username
V 3
dev
END

This config file tells subversion that whenever it wishes to access repositories hosted on master.securerepo.com, it should do so using the username 'dev' and consulting gpg-agent for the password.

Let's Do This

Before we tie all this together, let's look at how this supposed to work. Suppose you enter the command:

$ svn checkout https://master.securerepo.com/projects/borken/trunk

Subversion will look for the configuration file that correspond to the realm string <https://master.securerepo.com:443 SVN>. In our example above, it will find this in the file named 3f08d77847ea42f0b7b1ccd66fd14138. It will then use this filename to ask gpg-agent for the credentials matching the keygrip 3f08d77847ea42f0b7b1ccd66fd14138. Our goal, therefore, is to to preset our passphrase for this hex value using the password found in 1password.

Here's one solution to accomplish this:

# sign in to 1password
$ eval $(op signin allmysecrets)

# store the svn repo password in a shell variable
$ svn_password=$(op get item 'master svn account' | \
  jq -r '.details.fields[] | select(.designation=="password").value')

# store the password in gpg-agent with the correct hex key
$ /usr/lib/gnupg/gpg-preset-passphrase -c -P "$svn_password" 3f08d77847ea42f0b7b1ccd66fd14138

# And we're done! svn should find the credentials in gpg-agent and
# not bother asking us
$ svn checkout https://master.securerepo.com/projects/borken/trunk src
$ cd src
$ svn switch ^/branches/feature-x

I have a shell script that contains a mapping of svn domains to 1password uuid's. This let's me run a single command to authenticate  all svn domains in one go. Every time I run it I feel a bit of joy; my passwords are securely stored in 1password and they are seamlessly available to svn.

It was a long journey to get this all sorted, but it was so worth it!

Preparing for the Unthinkable, Part 2 - Trauma Kits

Let's Talk Trauma Kits

Shira and I recently attended Until Help Arrives (UHA) training, a County designed class to train bystanders to save lives during a mass casualty event. In the class, they highlighted a number of store-bought materials minimally trained individuals can use to save lives. I've compiled these items to form two different types of trauma kits.

The first kit is a full sized, deluxe version. It's bulky, but contains everything a person needs to execute the TECC Active Bystander Guidelines. It's intended to be staged near a potential catastrophe: say, in a desk drawer, behind a bimah, or in the trunk of a car.

The pocket version is more compact, but requires that you augment it with materials in the field. It's intended to go in your purse, or man bag. It gets deployed when a crisis happens at an unexpected location, like a concert or a movie theater.

Before I dive into the details of each kit, let's talk about a favorite topic: improvisation.

On Improvisation

Whenever the topic of trauma kits comes up, there's typically mention of two principles: first, that the items found in a trauma kit can be improvised from everyday materials. If you have a table cloth, fork and steak knife, then you can craft a tourniquet with relative ease. The second principle: for a minimally trained individual, purpose-built devices are going to be far more successful then their improvised cousins. So, yes you can make a tourniquet out of a table cloth, but in a high-stress situation where a loved one has minutes to live, you're going to be far more successful with a SAM XT tourniquet than the home made version.

I would  add to that discussion that there's broadly two flavors of improvisation: planned and unplanned. One common improvisation is to create a chest seal out of a Ziploc bag and tape. Consider Alice who happens to keep a Ziploc bag and tape in her purse. Both these items are nearly weightless, bulk-less and have countless uses. If an emergency happens, Alice can improvise a chest seal out of items she knows she has on her person. Bob, on the other hand, hasn't staged these items. If an emergency happens, he needs to first search out a baggie and tape before he can start improvising. The best option is for both Alice and Bob to have access to a stocked trauma kit which would contain a medical grade chest seal. If that's not possible, I'd argue that Alice is in a far better position than Bob to deliver care even though they are both improvising.

My point: if you have to fallback on improvisation, a little planning can go a long way.

The Full Size Kit

Primary Tourniquet: SAM XT - this is the UHA's recommended tourniquet and I see why. Its satisfying click when you tighten it in place helps assure you  that you're using it properly. In the situation above where a loved one is bleeding uncontrollably, this is the device you want on hand.

Secondary Tourniquet: SWAT-T Tourniquet. Not as easy to deploy as the SAM-XT, but still a reputable, field proven tourniquet. It has the advantage of being multi-purpose and working on limbs of any size, including children and pets.

Pressure Dressing: 6" Israeli Bandage. The Israeli Bandage is a legendary piece of battlefield kit. Instead of having to carefully dress a wound with a gauze pads and then wrap it with an Ace-wrap to keep it in place, the Israeli Bandage provides an all in one solution. For bleeding that doesn't call for a tourniquet the Israeli Bandage is the way to go.

Secondary Pressure Dressing: SWAT-T Tourniquet + Gauze.

Wound Packing Aid: Rolled Gauze. This may get swapped out with hemostatic gauze at some point, but for now, cheap, multi-purpose gauze is the winner.

Chest Seal: HyFin Vent Chest Seal. Bulky and relatively expensive these do one job, and do it well. If you ever need to do deploy a chest seal, you're going to be glad you didn't skimp.

Hypothermia/Shock Treatment: S.O.L. Heatsheet Emergency Blanket. In theory, a cheap (around $1.00) Mylar blanket will keep a victim warm while you take other actions to raise their body temperature. However, I like to splurge on the upgraded Heatsheet version because they are less likely to tear, are quieter to use and I've got a track record of using them successfully in the woods.

Other Tools: Medical Scissors and Nitrile Gloves. The scissors are helpful in exposing wounds. The gloves are standard PPE.

The Pocket Version

Primary Tourniquet: SWAT-T. Given the size restrictions of the pocket kit, the SWAT-T is the way to go.

Primary Pressure Bandage: SWAT-T + any fabric you have on hand. The fabric can be almost anything: a handkerchief, COVID mask, part of your clothing, etc.

Wound Packing Aid: Any fabric you have on hand. This may be on your person, a handkerchief, Buff, t-shirt, etc. Or, this may be in your environment: a sheet, towel, table cloth, curtains, etc.

Chest Seal: improvised from the bag that holds the kit, and the included tape.

Hypothermia/Shock Treatment: S.O.L. Heatsheet Emergency Blanket.

Other Tools: Leukotape and Nitrile Gloves. The Luekotape is a terrifically useful item to have and has far more uses than just creating a chest seal.

Pro Tip: All the items I purchased for the above kits were reimbursed when Shira submitted a Flex Spending Account (FSA) claim. She classified both styles of tourniquets, the chest seals and the the Israeli bandages under the section pertaining to bandages.  So if you find yourself with extra FSA bucks at the end of the year, it's a safe bet to put some of that money towards emergency medical supplies.
