Bringing dwm Shortcuts to GNOME 2023-11-02 The dwm window manager is my standard "go-to" for most of my personal laptop environments. For desktops with larger, higher resolution monitors I tend to lean towards using GNOME. The GNOME DE is fairly solid for my own purposes. This article isn't going to deep dive into GNOME itself, but instead highlight some minor configuration changes I make to mimic a few dwm shortcuts. For reference, I'm running GNOME 45.0 on Ubuntu 23.10 Setting Up Fixed Workspaces When I use dwm I tend to have a hard-set amount of tags to cycle through (normally 4-5). Unfortunately, dynamic rendering is the default for workspaces (ie. tags) in GNOME. For my personal preference I set this setting to fixed. We can achieve this by opening Settings > Multitasking and selecting "Fixed number of workspaces". Screenshot of GNOME's Multitasking Settings GUI Setting Our Keybindings Now all that is left is to mimic dwm keyboard shortcuts, in this case: ALT + $num for switching between workspaces and ALT + SHIFT + $num for moving windows across workspaces. These keyboard shortcuts can be altered under Settings > Keyboard > View and Customize Shortcuts > Navigation. You'll want to make edits to both the "Switch to workspace n" and "Move window to workspace n". Screenshot of GNOME's keyboard shortcut GUI: switch to workspace Screenshot of GNOME's keyboard shortcut GUI: move window to workspace That's it. You're free to include even more custom keyboard shortcuts (open web browser, lock screen, hibernate, etc.) but this is a solid starting point. Enjoy tweaking GNOME!
The X220 ThinkPad is the Best Laptop in the World 2023-09-26 The X220 ThinkPad is the greatest laptop ever made and you're wrong if you think otherwise. No laptop hardware has since surpassed the nearly perfect build of the X220. New devices continue to get thinner and more fragile. Useful ports are constantly discarded for the sake of "design". Functionality is no longer important to manufacturers. Repairability is purposefully removed to prevent users from truly "owing" their hardware. It's a mess out there. But thank goodness I still have my older, second-hand X220. Specs Before I get into the details explaining why this laptop is the very best of its kind, let's first take a look at my machine's basic specifications: CPU: Intel i7-2640M (4) @ 3.500GHz GPU: Intel 2nd Generation Core Processor Memory: 16GB DDR3 OS: Arch Linux / OpenBSD Resolution: 1366x768 With that out of the way, I will break down my thoughts on the X220 into five major sections: Build quality, available ports, the keyboard, battery life, and repairability. Build Quality The X220 (like most of Lenovo's older X/T models) is built like a tank. Although sourced from mostly plastic, the device is still better equipped to handle drops and mishandling compared to that of more fragile devices (such as the MacBook Air or Framework). This is made further impressive since the X220 is actually composed of many smaller interconnected pieces (more on this later). A good litmus test I perform on most laptops is the "corner test". You grab the base corner of a laptop in its open state. The goal is to see if the device displays any noticeable give or flex. In the X220's case: it feels rock solid. The base remains stiff and bobbing the device causes no movement on the opened screen. I'm aware that holding a laptop in this position is certainly not a normal use case, but knowing it is built well enough to do so speaks volumes of its construction. The X220 is also not a lightweight laptop. This might be viewed as a negative for most users, but I actually prefer it. I often become too cautious and end up "babying" thinner laptops out of fear of breakage. A minor drop from even the smallest height will severely damage these lighter devices. I have no such worries with my X220. As for the laptop's screen and resolution: your mileage may vary. I have zero issues with the default display or the smaller aspect ratio. I wrote about how I stopped using an external monitor, so I might be a little biased. Overall, this laptop is a device you can snatch up off your desk, whip into your travel bag and be on your way. The rugged design and bulkier weight help put my mind at ease - which is something I can't say for newer laptop builds. Ports Ports. Ports Everywhere. I don't think I need to explain how valuable it is to have functional ports on a laptop. Needing to carrying around a bunch of dongles for ports that should already be on the device just seems silly. The X220 comes equipped with: 3 USB ports (one of those being USB3 on the i7 model) DisplayPort VGA Ethernet SD Card Reader 3.5mm Jack Ultrabay (SATA) Wi-Fi hardware kill-switch Incredibly versatile and ready for anything I throw at it! Keyboard The classic ThinkPad keyboards are simply that: classic. I don't think anyone could argue against these keyboards being the golden standard for laptops. It's commendable how Lenovo managed to package so much functionality into such a small amount of real estate. Most modern laptops lack helpful keys such as Print Screen, Home, End, and Screen Lock. They're also an absolute joy to type on. The fact that so many people go out of their way to mod X230 ThinkPad models with X220 keyboards should tell you something... Why Lenovo moved away from these keyboards will always baffle me. (I know why they did it - I just think it's stupid). Did I mention these classic keyboards come with the extremely useful Trackpoint as well? Battery Life Author's Note: This section is very subjective. The age, quality, and size of the X220's battery can have a massive impact on benchmarks. I should also mention that I run very lightweight operating systems and use DWM as opposed to a heavier desktop environment. Just something to keep in mind. The battery life on my own X220 is fantastic. I have a brand-new 9-cell that lasts for roughly 5-6 hours of daily work. Obviously these numbers don't come close to the incredible battery life of Apple's M1/M2 chip devices, but it's still quite competitive against other "newer" laptops on the market. Although, even if the uptime was lower than 5-6 hours, you have the ability to carry extra batteries with you. The beauty of swapping out your laptop's battery without needing to open up the device itself is fantastic. Others might whine about the annoyance of carrying an extra battery in their travel bag, but doing so is completely optional. A core part of what makes the X220 so wonderful is user control and choice. The X220's battery is another great example of that. Repairability The ability to completely disassemble and replace almost everything on the X220 has to be one of its biggest advantages over newer laptops. No glue to rip apart. No special proprietary tools required. Just some screws and plastic snaps. If someone as monkey-brained as me can completely strip down this laptop and put it back together again without issue, then the hardware designers have done something right! Best of all, Lenovo provides a very detailed hardware maintenance manual to help guide you through the entire process. My disassembled X220 when I was reapplying the CPU thermal paste. Bonus Round: Price I didn't list this in my initial section "breakdown" but it's something to consider. I purchased my X220 off eBay for $175 Canadian. While this machine came with a HDD instead of an SSD and only 8GB of total memory, that was still an incredible deal. I simply swapped out the hard-drive with an SSD I had on hand, along with upgrading the DDR3 memory to its max of 16. Even if you needed to buy those components separately you would be hard-pressed to find such a good deal for a decent machine. Not to mention you would be helping to prevent more e-waste! What More Can I Say? Obviously the title and tone of this article is all in good fun. Try not to take things so seriously! But, I still personally believe the X220 is one of, if not the best laptop in the world.
Converting HEIF Images with macOS Automator 2023-07-21 Often times when you save or export photos from iOS to iCloud they often render themselves into heif or heic formats. Both macOS and iOS have no problem working with these formats, but a lot of software programs will not even recognize these filetypes. The obvious step would just be to convert them via an application or online service, right? Not so fast! Wouldn't it be much cleaner if we could simply right-click our heif or heic files and convert them directly in Finder? Well, I've got some good news for you... Basic Requirements You will need to have Homebrew installed You will need to install the libheif package through Homebrew: brew install libheif Creating our custom Automator script For this example script we are going to convert the image to JPG format. You can freely change this to whatever format you wish (PNG, TIFF, etc.). We're just keeping things basic for this tutorial. Don't worry if you've never worked with Automator before because setting things up is incredibly simple. Open the macOS Automator from the Applications folder Select Quick Option from the first prompt Set "Workflow receives current" to image files Set the label "in" to Finder From the left pane, select "Library > Utilities" From the presented choices in the next pane, drag and drop Run Shell Script into the far right pane Set the area "Pass input" to as arguments Enter the following code below as your script and type ⌘-S to save (name it something like "Convert HEIC/HEIF to JPG") for f in "$@" do /opt/homebrew/bin/heif-convert "$f" "${f%.*}.jpg" done Making Edits If you ever have the need to edit this script (for example, changing the default format to png), you will need to navigate to your ~/Library/Services folder and open your custom heif Quick Action in the Automator application. Simple as that. Happy converting! If you're interested, I also have some other Automator scripts available: Batch Converting Images to webp with macOS Automator Convert Files to HTML with macOS Automator Quick Actions
Blogging for 7 Years 2023-06-24 My first public article was posted on June 28th 2016. That was seven years ago. In that time, quite a lot has changed in my life both personally and professionally. So, I figured it would be interesting to reflect on these years and document it for my own personal records. My hope is that this is something I could start doing every 5 or 10 years (if I can keep going that long!). This way, my blog also serves as a "time capsule" or museum of the past... Fun Facts This Blog: I originally started blogging on bradleytaunt.com using WordPress, but since then I have changed both my main domain and blog infrastructure multiple times. At a glance I have used: Jekyll Hugo Blot Static HTML/CSS PHPetite Shinobi pblog barf Currently using! Personal: As with anyone over time, the personal side of my life has seen the biggest updates: Married the love of my life (after knowing each other for ~14 years!) Moved out into rural Ontario for some peace and quiet Had three wonderful kids with said wife (two boys and a girl) Started noticing grey sprinkles in my stubble (I guess I can officially call myself a "grey beard"?) Professionally: Pivoted heavily into UX research and design for a handful of years (after working mostly with web front-ends) Recently switched back into a more fullstack development role to challenge myself and learn more Nothing Special This post isn't anything ground-breaking but for me it's nice to reflect on the time passed and remember how much can change in such little time. Hopefully I'll be right back here in another 7 years and maybe you'll still be reading along with me!
More in programming
I'm a big (neo)vim buff. My config is over 1500 lines and I regularly write new scripts. I recently ported my neovim config to a new laptop. Before then, I was using VSCode to write, and when I switched back I immediately saw a big gain in productivity. People often pooh-pooh vim (and other assistive writing technologies) by saying that writing code isn't the bottleneck in software development. Reading, understanding, and thinking through code is! Now I don't know how true this actually is in practice, because empirical studies of time spent coding are all over the place. Most of them, like this study, track time spent in the editor but don't distinguish between time spent reading code and time spent writing code. The only one I found that separates them was this study. It finds that developers spend only 5% of their time editing. It also finds they spend 14% of their time moving or resizing editor windows, so I don't know how clean their data is. But I have a bigger problem with "writing is not the bottleneck": when I think of a bottleneck, I imagine that no amount of improvement will lead to productivity gains. Like if a program is bottlenecked on the network, it isn't going to get noticeably faster with 100x more ram or compute. But being able to type code 100x faster, even with without corresponding improvements to reading and imagining code, would be huge. We'll assume the average developer writes at 80 words per minute, at five characters a word, for 400 characters a minute.What could we do if we instead wrote at 8,000 words/40k characters a minute? Writing fast Boilerplate is trivial Why do people like type inference? Because writing all of the types manually is annoying. Why don't people like boilerplate? Because it's annoying to write every damn time. Programmers like features that help them write less! That's not a problem if you can write all of the boilerplate in 0.1 seconds. You still have the problem of reading boilerplate heavy code, but you can use the remaining 0.9 seconds to churn out an extension that parses the file and presents the boilerplate in a more legible fashion. We can write more tooling This is something I've noticed with LLMs: when I can churn out crappy code as a free action, I use that to write lots of tools that assist me in writing good code. Even if I'm bottlenecked on a large program, I can still quickly write a script that helps me with something. Most of these aren't things I would have written because they'd take too long to write! Again, not the best comparison, because LLMs also shortcut learning the relevant APIs, so also optimize the "understanding code" part. Then again, if I could type real fast I could more quickly whip up experiments on new apis to learn them faster. We can do practices that slow us down in the short-term Something like test-driven development significantly slows down how fast you write production code, because you have to spend a lot more time writing test code. Pair programming trades speed of writing code for speed of understanding code. A two-order-of-magnitude writing speedup makes both of them effectively free. Or, if you're not an eXtreme Programming fan, you can more easily follow the The Power of Ten Rules and blanket your code with contracts and assertions. We could do more speculative editing This is probably the biggest difference in how we'd work if we could write 100x faster: it'd be much easier to try changes to the code to see if they're good ideas in the first place. How often have I tried optimizing something, only to find out it didn't make a difference? How often have I done a refactoring only to end up with lower-quality code overall? Too often. Over time it makes me prefer to try things that I know will work, and only "speculatively edit" when I think it be a fast change. If I could code 100x faster it would absolutely lead to me trying more speculative edits. This is especially big because I believe that lots of speculative edits are high-risk, high-reward: given 50 things we could do to the code, 49 won't make a difference and one will be a major improvement. If I only have time to try five things, I have a 10% chance of hitting the jackpot. If I can try 500 things I will get that reward every single time. Processes are built off constraints There are just a few ideas I came up with; there are probably others. Most of them, I suspect, will share the same property in common: they change the process of writing code to leverage the speedup. I can totally believe that a large speedup would not remove a bottleneck in the processes we currently use to write code. But that's because those processes are developed work within our existing constraints. Remove a constraint and new processes become possible. The way I see it, if our current process produces 1 Utils of Software / day, a 100x writing speedup might lead to only 1.5 UoS/day. But there are other processes that produce only 0.5 UoS/d because they are bottlenecked on writing speed. A 100x speedup would lead to 10 UoS/day. The problem with all of this that 100x speedup isn't realistic, and it's not obvious whether a 2x improvement would lead to better processes. Then again, one of the first custom vim function scripts I wrote was an aid to writing unit tests in a particular codebase, and it lead to me writing a lot more tests. So maybe even a 2x speedup is going to be speed things up, too. Patreon Stuff I wrote a couple of TLA+ specs to show how to model fork-join algorithms. I'm planning on eventually writing them up for my blog/learntla but it'll be a while, so if you want to see them in the meantime I put them up on Patreon.
Here’s Jony Ive in his Stripe interview: What we make stands testament to who we are. What we make describes our values. It describes our preoccupations. It describes beautiful succinctly our preoccupation. I’d never really noticed the connection between these two words: occupation and preoccupation. What comes before occupation? Pre-occupation. What comes before what you do for a living? What you think about. What you’re preoccupied with. What you think about will drive you towards what you work on. So when you’re asking yourself, “What comes next? What should I work on?” Another way of asking that question is, “What occupies my thinking right now?” And if what you’re occupied with doesn’t align with what you’re preoccupied with, perhaps it's time for a change.

There's no country on earth that does hype better than America. It's one of the most appealing aspects about being here. People are genuinely excited about the future and never stop searching for better ways to work, live, entertain, and profit. There's a unique critical mass in the US accelerating and celebrating tomorrow. The contrast to Europe couldn't be greater. Most Europeans are allergic to anything that even smells like a commercial promise of a better tomorrow. "Hype" is universally used as a term to ridicule anyone who dares to be excited about something new, something different. Only a fool would believe that real progress is possible! This is cultural bedrock. The fault lines have been settling for generations. It'll take an earthquake to move them. You see this in AI, you saw it in the Internet. Europeans are just as smart, just as inventive as their American brethren, but they don't do hype, so they're rarely the ones able to sell the sizzle that public opinion requires to shift its vision for tomorrow. To say I have a complicated relationship with venture capital is putting it mildly. I've spent a career proving the counter narrative. Proving that you can build and bootstrap an incredible business without investor money, still leave a dent in the universe, while enjoying the spoils of capitalism. And yet... I must admit that the excesses of venture capital are integral to this uniquely American advantage on hype. The lavish overspending during the dot-com boom led directly to a spectacular bust, but it also built the foundation of the internet we all enjoy today. Pets.com and Webvan flamed out such that Amazon and Shopify could transform ecommerce out of the ashes. We're in the thick of peak hype on AI right now. Fantastical sums are chasing AGI along with every dumb derivative mirage along the way. The most outrageous claims are being put forth on the daily. It's easy to look at that spectacle with European eyes and roll them. Some of it is pretty cringe! But I think that would be a mistake. You don't have to throw away your critical reasoning to accept that in the face of unknown potential, optimism beats pessimism. We all have to believe in something, and you're much better off believing that things can get better than not. Americans fundamentally believe this. They believe the hype, so they make it come to fruition. Not every time, not all of them, but more of them, more of the time than any other country in the world. That really is exceptional.
