PSA: negate your tests and make sure they fail!
I have what I thought was a weird and slightly paranoid habit. When I write tests sometimes just as a sanity check negate the assertion to make sure the test fails and isn't a false positive. Almost always fails as expected.
But not today! Turns out I had forgotten to wrap my equality check in an assertion so it would always pass. It freaks me out to imagine pushing a test that always passes not just because it doesn't do its job, but could also obscure a bug and trick me into thinking it works differently than it does. Broken tests are the worst!
But it pays to be paranoid.
I walk by our devops dashboard several times per day. It keeps track of key metrics for all our live services. I noticed an interesting trend the last few weeks.
3 weeks ago: all metrics green
2 weeks ago: 1 metric red
1 week ago: 1 metric still red
this week: 1 metric still red but covered with a post it note
I'm such an idiot.
Spilled water on my MacBook today. Not that much water, but the cup landed right in the middle of my keyboard.
Worst part is I was gaming with my sister and didn't want to stop. So I wiped it off and shook it out a bit and kept playing. A bit later the screen started flickering and eventually went black.
Finally my brain turned on and I switched it off, shook out some more water, and set it up to dry. Just hoping it's not too late.
At least the drying setup recommended by the internet is pretty hilarious looking.
Now we play the waiting game. They say 72 hours before turning it on again. Seems a bit extreme. Will there still be moisture evaporating 3 days later? Not sure I can wait that long to see if it's toast.
Such an idiot.14
We've been using private GitHub repos as a distribution method for our personal npm packages at work for years.
I finally got sick of it and did the work to publish them to artifactory yesterday. Today, I worked out the remaining kinks, fixed the CI builds, and wrote a wiki page explaining the change with step by step migration instructions and sent it around to the rest of the devs. And it's working great!
I feel simultaneously like a hero for finally getting this fixed and an idiot for putting up with it for so long.
Also thankful for my devops friend who helped a bunch.1
Any recommendations for moving a blog?
My wife and I just cancelled our account with siteground hosting a WordPress blog. Looking for a cheaper alternative. Willing to get my hands dirty as a web dev, but would like a nice CMS experience for my wife. Also want to keep our existing content. If we can keep our custom domain somehow that would be a win.
This morning I kept falling back asleep after the alarm went off, drifting in and out of a dream about programming.
My wife finally said "no more sleeping".
Still mostly sleep, I replied very confidently "you can't sleep in a sandbox!".
I was dreaming I was in a code sandbox. Obviously sleeping is not allowed.
Jeez, my head has been really full of programming since this conference. (One of the talks was on codesandbox).
Me: *adds a shiny new graph to our foos web app showing player ratings*
Fred: Can I please have a button to see just my scores?
Me: *adds "JUST FRED" button*
Fred: perfect, thanks4
Just attended my first conference and it was awesome! So many new ideas, but also tired and overloaded. Can't decide if I should code tonight, go to bed early, or just do something mindless.1
I had an interesting mystery the other day. I work in the UK, but I'm working remotely from the US for a while. First day, I made some changes, ran the tests and they failed. Weird part was the failing test was for a component I hadn't touched. I took a closer look, and realized it was a date off by several hours. The test was checking that a passed in date appears in the output. But it was creating the date by parsing a string. The library I was using defaults to local time, but the component uses UTC. So, I had inadvertently created a unit test that only passes when run from UTC. But I had never noticed before because my work is in that timezone. Yikes!
Why is so Fitbit so bad at multiple time zones??
Guess what, people get on planes and travel.
Every time, my Fitbit gets so screwed up, including things like changing previous step counts, or duplicating an entire day of steps.
I understand MTZ is a tough problem, but this is just unacceptable. I'm not obsessed with my steps, but when your product is all about counting something, seems like you should be more careful to avoid double counting or not counting at all. Seriously, how much R&D have they invested in their hardware and apps, but it completely fails when you travel. Get it together!1
I want to buy a beer for everyone who developed the mobile pass app. Just breezed through immigration and customs without waiting in the 1 hour+ line. Technology wins. Cheers!1
Night before flying internationally includes the following checklist:
- check VPN works, can access frontend sites and hit the backend
- git push4
A common scenario strikes again today:
- Blocked on a problem at the end of the day
- Tell my wife I'm headed home
- Inspiration strikes
- time flies by coding in the zone
- realize I'm super late
- run out the door like a crazy person1
Just moved countries and started a new job at an awesome company, which is so great I have nothing yet to rant about.
Oh here goes: almost three weeks with no internet at home and no end in sight.2
Things you should not say on your last day of work:
If I broke it, I think it would be pretty obvious.
Coding has given me the ability to turn my favorite hobby into a career. This in turn gave me the chance to take jobs in three countries so far (US, Germany, UK). So, I can explore the world with lovely wife while doing something I'm really passionate about and constantly learning. It also allows me to relate more to my dad, a software engineer of about 30 years who got me started when I was a kid.
In short, coding changed everything for me.
PS: I met my wife in intro to CS, though she's not a developer.
Computer does a BSOD right at the end of a tiebreaker competitive overwatch match where the enemy is about to cap the point and win. I'm one of the tanks. Hard reboot and back in the game within 45s. Just barely hold them off in overtime and win the match. Epic!
Thank God for SSDs!4

WHEN DRAGGING A PICTURE INTO A WEB PAGE I NEVER WANT TO NAVIGATE TO A PAGE WITH JUST THAT IMAGE. WHY NO WARNING BEFORE LEAVING THE PAGE. WHY DON'T YOU SAVE TEXT LOCALLY. WHY DOES THE WEB SUCK SO HARD. AAAGGGHHHH.

When you offer to help out a fellow coworker on the top priority feature he is developing and he just sends you the branch and stops working on it.2
I spent more than an hour trying trying to debug why two functions were always returning undefined. I even put in conditional breakpoints and executed the statements to confirm the logic was correct.
I forgot return.4
When you are tearing you hair out trying to figure out why the PR you're reviewing isn't working. Then you realize you forgot to pull the latest changes!
Anyone else used Stack Overflow for many years without ever asking or answering a single question?20
