Patching in production - it's every QA engineer's worst nightmare and every developer's necessary evil. But here's the thing: a quick fix isn't always a real fix. If you don't fix it right the first time, you're just rolling out a "Version 2.0" of the original problem.
In today's post, we'll dive into a real-world example of why proper patching matters, how bad fixes spiral into bigger issues, and the key takeaways to ensure you fix it right the first time.
Act 1: The $100K Bug
Picture this: The release just went live. The team is celebrating, and the next sprint is on the horizon. But then -
A critical database issue emerges.
Customers with exactly $100,000 in spend are seeing a bug. Panic sets in. A developer rushes out a quick fix and proudly announces:
"Deployed to QA! Issue resolved!"
QA runs a test. The problem disappears. Crisis averted! Right?
Wrong.
Act 2: The $1M Curveball
Just as the dev team is patting themselves on the back, QA runs another check and finds an issue:
Customers with $1 million in spend still have the same problem.
Turns out, the developer's fix was too specific - it only solved the $100K edge case but didn't fix the underlying logic flaw.
The result? More time lost, more stress, and a frustrated CTO wondering why this wasn't caught earlier.
Act 3: The Right Fix ? No Sequels Required
So, what happens next?
This time, instead of another band-aid fix, the team takes the time to analyze the root cause. The result?
A real fix that resolves the logic flaw across all spend levels.
No more last-minute patches needed in the next release.
A cleaner, simpler solution that prevents future surprises.
Moral of the story? A fast patch isn't always a good patch.
The QA Lesson: Test for the Unexpected
This issue wasn't caught before the release because it was an edge case - an inadvertent change in spend calculations exposed an unseen bug. Here's what QA learned:
Expand test coverage: Automation tests now include $100K, $500K, and $1M transactions - not just a sample range.
Shift left testing: QA collaborates with Devs earlier to ensure they're fixing the root cause, not just the reported issue.
Proactive validation: Instead of reacting to bugs, the team tests for unexpected scenarios before they reach production.
The best patch? The one you don't have to make twice. Fix it right the first time.
Recently, I came across a VHS tape dated January 2001 that contained a fascinating collection of commercials, offering a time capsule of early 21st-century marketing. Watching these ads is a reminder of how technology, business, and culture have evolved over the past two decades. From dial-up internet to dot-com era optimism, here's a look at some of the commercials found on the tape:
Watch the Video
AOL 6.0 - The Internet, Simplified
At the dawn of the 2000s, America Online (AOL) was still a dominant force in getting people connected to the internet. The AOL 6.0 commercial hyped up the latest version of its software, touting "faster, easier" browsing and new features that would make online life more convenient. Of course, that meant more CDs in the mail!
Disney's California Adventure - The Newest Theme Park
Disneyland was gearing up to open its highly anticipated second park in Anaheim: Disney's California Adventure. This commercial captured the excitement, showing off new attractions inspired by the Golden State. At the time, expectations were high - though the park's early years saw mixed reviews before major overhauls like Cars Land brought it to life.
3Com - "Simple Sets You Free"
Networking giant 3Com was trying to sell the idea that simplicity in technology leads to better productivity. The commercial pushed the company's vision of seamless networking, emphasizing the ease of setting up business communications - an idea that companies like Cisco and HP would later dominate.
Novell - A Name From the Past
Remember Novell? In the early 2000s, they were a significant player in network software and enterprise computing. This commercial pitched Novell's role in making businesses more efficient, though, in hindsight, the company struggled to maintain relevance as Microsoft and Linux gained ground.
Dell Dimension - $849 for a Complete Computer System
Dell was a powerhouse in the PC market, and this ad promoted an $849 complete computer package. This price included the tower, monitor, and printer - a deal that seemed affordable at the time. It's a stark contrast to today's tech landscape, where many people spend that much (or more) on just a smartphone!
Xerox Color Inkjet Printers
Xerox, traditionally known for photocopiers, was making a push into color inkjet printing. Their ad focused on vibrant, high-quality prints, though inkjet technology would soon be overshadowed by the rise of affordable laser printers.
Microsoft - "Software for the Agile Business"
Microsoft's early 2000s commercials leaned heavily into business solutions. This ad promoted Microsoft's enterprise software, showcasing how it could help companies adapt to fast-changing markets - something Microsoft continues to dominate with Office 365 and Azure today.
Miller Lite - "It's Miller Time" at a Medical Conference
One of the more amusing ads in the collection, this Miller Lite commercial featured a quirky setting - a medical conference where a doctor was talking about DNA and several people in the audience were cheering as if at a football game. The second part of the commercial was a chance to win a Miller Time inflatable chair, proving that beer marketing in the early 2000s still had a fun, playful angle.
CNBC - "Log On to Win an Audi GT"
Even business news networks were running major promotions! CNBC encouraged viewers to log on for a chance to win an Audi GT and other prizes. It's interesting to see how online contests were gaining traction as a marketing tool back then, something that would only grow in the years to come.
Final Thoughts
Watching this collection of commercials from January 2001 is a fun trip down memory lane. It captures an era when dial-up internet was still common, companies were optimistic about the tech boom, and TV ads still played a huge role in marketing.

The iMac Retina 5K, 27-inch (2019) might not be Apple's latest all-in-one, but it still holds its own. It was one of the last Intel-based iMacs, and for some users, that makes it special. Let's dive into some fun facts about this powerhouse Mac!
User-Upgradeable RAM - A Dying Feature
One of the best things about the 2019 iMac is its user-accessible RAM slot. Unlike today's sealed Apple Silicon Macs, this model lets you upgrade the RAM yourself. Officially, Apple supports up to 64GB, but tech enthusiasts have successfully installed 128GB. That's a serious boost for video editors, developers, and anyone running resource-heavy tasks.
That Gorgeous 5K Display
The Retina 5K display (5120?2880 resolution) is still stunning. It supports P3 wide color gamut and True Tone, making it a favorite for designers and video editors. For years, people considered it the gold standard for built-in Mac displays. In fact, it was so good that many professionals stuck with this iMac instead of shelling out thousands for an external 5K or 6K monitor.
The iMac That Outlived the Mac Pro
When Apple discontinued the iMac Pro (2017) in 2021, many professionals looked to the 2019 iMac as a worthy replacement. It had an option for a Core i9 processor, which outperformed some base-level 2019 Mac Pro configurations in certain single-core tasks. Not bad for an all-in-one!
Boot Camp and Virtualization Still Matter
Unlike Apple Silicon Macs, this iMac still supports Boot Camp, meaning you can run Windows natively. It's also a great machine for running older versions of macOS, making it useful for developers and legacy software users.
The T2 Chip - A Blessing and a Curse
Apple's T2 security chip improved SSD encryption, microphone privacy, and camera processing. It also enabled Hey Siri without an iPhone nearby. But it came with a trade-off - it made some repairs harder and added restrictions on downgrading macOS.
Why People Still Love This iMac in 202
Some people still prefer this model over newer Macs. Why?
It supports Intel-based apps without emulation.
You can boot from external drives more easily.
It's still one of the best-looking all-in-one Macs ever made.
The 2019 iMac 5K isn't just a relic of the past - it's a Mac with a lasting legacy. If you still have one, you've got a piece of Apple history that's worth holding onto!
When working with stereo audio in Final Cut Pro, you might occasionally run into a situation where one side of your track isn't quite up to par. Maybe the left channel is too boomy, or - as was my case - the right channel is just plain "garbage." Fortunately, Final Cut Pro provides a straightforward way to split your stereo audio into separate mono tracks, giving you the flexibility to disable or adjust the problematic channel without affecting the overall project.
In this blog post, I'll walk you through the step-by-step process of splitting a stereo audio file into dual mono tracks and disabling one channel. This method can be particularly useful if you need to reduce background noise or balance your mix when one track's audio levels are off.
Step 1: Import and Select Your Audio Clip
Import Your Clip: Start by importing the clip with your stereo audio into Final Cut Pro.
Select the Clip: In your timeline, click on the clip to ensure it's selected. You'll need to see the clip's details in the Inspector panel.
Step 2: Open the Audio Inspector
Access the Inspector: With your clip selected, open the Inspector panel by clicking the Inspector button in the top right corner of Final Cut Pro.
Switch to Audio: Make sure you're on the Audio tab where you can see all the properties related to your clip's audio configuration.
Step 3: Change the Audio Configuration to Dual Mono
Locate Audio Configuration: In the Audio Inspector, look for the Audio Configuration section. This area is where you can adjust how Final Cut Pro handles your audio channels.
Select Dual Mono: Change the configuration from stereo to Dual Mono. By doing so, Final Cut Pro splits your stereo file into two separate mono tracks - one for the left channel and one for the right.
Step 4: Disable the Unwanted Track
Identify the Problematic Track: Since my right track was causing issues, I needed to disable it. In the Inspector, after switching to Dual Mono, you'll see separate settings for each channel.
Turn Off the Track: Locate the Dialogue checkbox for the track you wish to disable. Simply click on the checkbox for the problematic track (in my case, the right channel) to turn it off. This effectively mutes the audio coming from that channel without affecting the left channel.
Step 5: Fine-Tuning and Playback
Play Back Your Clip: After disabling the unwanted track, play back your clip to ensure that the audio now meets your expectations. The background noise or unwanted audio should now be reduced or eliminated.
Adjust as Needed: If you find that you need further tweaks, you can always revisit the Audio Inspector to make more adjustments. Sometimes you might want to apply additional filters or volume changes to get the perfect balance.
Why Use Dual Mono?
Using Dual Mono is a powerful way to gain more control over your audio tracks in Final Cut Pro. It allows you to isolate and modify individual channels - perfect for scenarios where: - One channel has excessive background noise. - A channel is corrupted or has poor-quality audio. - You need to create a specific audio effect by treating each channel differently.
This method not only improves your audio quality but also saves time in the editing process by avoiding the need for additional software or complex workarounds.
Conclusion
Splitting a stereo audio file into dual mono tracks and disabling one channel is a simple yet effective technique in Final Cut Pro. Whether you're dealing with problematic audio or just want more control over your mix, these steps can help you achieve a cleaner, more professional sound.
The print() function is one of the most fundamental and frequently used functions in Python. While it's typically used to display output in a straightforward manner, you can get creative with it to format and present information in a more engaging way. In this post, we'll explore a fun and practical technique to enhance the way information is displayed in Python.
Printing Inline with end=
By default, print() adds a newline after each output. However, you can change this behavior using the end= parameter.
import random# Print numbers on the same line, separated by commasfor i inrange(5):print(random.randint(1, 99), end=", "if i <4else"n")# Print numbers on the same line, separated by spacesfor i inrange(5):print(random.randint(1, 99), end=" ")print("nDone!") # Moves to a new line after the loop
Why this is useful?
It helps create compact and clean output.
You control when to insert a new line or separator dynamically.
On my desk at work, among the monitors, keyboards, and Post-it notes, sits a little Hot Wheels model of the Scooby-Doo Mystery Machine. It's more than just a cool piece of nostalgia - it's a daily reminder of what QA is all about.
Let's take a closer look at the Mystery Machine and how it symbolizes the spirit of a great QA team.
The Mystery Machine: A Rolling QA Headquarters
The Mystery Machine isn't just a van. It's a mobile base of operations where the gang works together to solve mysteries. Inside, Fred crafts the plans, Velma deciphers the clues, Daphne thinks creatively, and Scooby and Shaggy keep things light (and occasionally find accidental solutions).
Sound familiar? That's a QA team in action.
Fred is your QA leader, strategizing the test plan.
Velma is the analytical mind, poring over logs and data.
Daphne represents the creative thinker, finding unconventional ways to break things (and help fix them).
Shaggy and Scooby? They're the humor and humanity, keeping spirits high even when the ghost of a recurring bug is haunting the build.
Together, this team tackles mysteries, just like we do when we're debugging or chasing down elusive defects.
Curiosity Fuels QA Success
If there's one trait the Scooby-Doo gang has in spades, it's curiosity. They never stop asking questions:
- What's causing the strange behavior?
- Where's the issue coming from?
- Is there a hidden clue we missed?
QA professionals share that relentless curiosity. It's what drives us to dig deeper when we encounter:
- Features that don't work as expected.
- Bugs that reappear like a masked villain.
- Performance issues that need investigation.
The lesson? Keep asking "why." Peel back every layer until you've uncovered the true culprit. Bugs, like spooky villains, are rarely what they seem at first glance.
"If It Weren't for You Meddling Kids!"
We've all heard Scooby-Doo's iconic line: "And I would have gotten away with it, too, if it weren't for you meddling kids!"
In QA, we're the meddling kids. Bugs try to sneak past us, but we're the ones who say, "Not so fast!" Developers might groan when we uncover another layer of issues, but deep down, they know we're making the product better.
Your meddling ensures that users experience software that is reliable, secure, and high quality. So, embrace the role - you're the hero of the story!
Teamwork Makes the Dream Work
The Scooby-Doo gang doesn't solve mysteries alone, and neither does QA. Fred, Velma, Daphne, Shaggy, and Scooby rely on each other's strengths, and that's what makes them successful.
In QA, collaboration is your superpower:
- Developers help you understand the code.
- Product managers share the user perspective.
- Stakeholders provide valuable insights.
Every voice matters. The best solutions come from combining perspectives and working as a team.
A Reminder for Every QA Professional
The Mystery Machine is more than just a van. It's a symbol of curiosity, persistence, and teamwork - the qualities that make QA essential.
