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.
Installing Older Versions of MongoDB on Arch Linux 2023-09-11 I've recently been using Arch Linux for my main work environment on my ThinkPad X260. It's been great. As someone who is constantly drawn to minimalist operating systems such as Alpine or OpenBSD, it's nice to use something like Arch that boasts that same minimalist approach but with greater documentation/support. Another major reason for the switch was the need to run older versions of "services" locally. Most people would simply suggest using Docker or vmm, but I personally run projects in self-contained, personalized directories on my system itself. I am aware of the irony in that statement... but that's just my personal preference. So I thought I would share my process of setting up an older version of MongoDB (3.4 to be precise) on Arch Linux. AUR to the Rescue You will need to target the specific version of MongoDB using the very awesome AUR packages: yay -S mongodb34-bin Follow the instructions and you'll be good to go. Don't forget to create the /data/db directory and give it proper permissions: mkdir -p /data/db/ chmod -R 777 /date/db What About My "Tools"? If you plan to use MongoDB, then you most likely want to utilize the core database tools (restore, dump, etc). The problem is you can't use the default mongodb-tools package when trying to work with older versions of MongoDB itself. The package will complain about conflicts and ask you to override your existing version. This is not what we want. So, you'll have to build from source locally: git clone https://github.com/mongodb/mongo-tools cd mongodb-tools ./make build Then you'll need to copy the built executables into the proper directory in order to use them from the terminal: cp bin/* /usr/local/bin/ And that's it! Now you can run mongod directly or use systemctl to enable it by default. Hopefully this helps anyone else curious about running older (or even outdated!) versions of MongoDB.
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!

<![CDATA[It has been a year since I set up my System76 Merkaat with Linux Mint. In July of 2024 I migrated from ChromeOS and the Merkaat has been my daily driver on the desktop. A year later I have nothing major to report, which is the point. Despite the occasional unplanned reinstallation I have been enjoying the stability of Linux and just using the PC. This stability finally enabled me to burn bridges with mainstream operating systems and fully embrace Linux and open systems. I'm ready to handle the worst and get back to work. Just a few years ago the frustration of troubleshooting a broken system would have made me seriously consider the switch to a proprietary solution. But a year of regular use, with an ordinary mix of quiet moments and glitches, gave me the confidence to stop worrying and learn to love Linux. linux a href="https://remark.as/p/journal.paoloamoroso.com/my-first-year-since-coming-back-to-linux"Discuss.../a Email | Reply @amoroso@oldbytes.space !--emailsub--]]>
The mystery In the previous article, I briefly mentioned a slight difference between the ESP-Prog and the reproduced circuit, when it comes to EN: Focusing on EN, it looks like the voltage level goes back to 3.3V much faster on the ESP-Prog than on the breadboard circuit. The grid is horizontally spaced at 2ms, so … Continue reading Overanalyzing a minor quirk of Espressif’s reset circuit → The post Overanalyzing a minor quirk of Espressif’s reset circuit appeared first on Quentin Santos.
Explaining nil interface{} gotcha in Go A footgun In Go empty interface is an interface without any methods, typed as interface{}. A zero value of interface{} is nil: var v interface{} // compiler sets this to nil, you could explicitly write = nil if v == nil { fmt.Printf("v is nil\n") } else { fmt.Printf("v is NOT nil\n") } Try online This prints: v is nil. However, this sometimes trips people up: type Foo struct { } var v interface{} var nilFoo *Foo // implicilty initialized by compiler to nil if nilFoo == nil { fmt.Printf("nilFoo is nil.") } else { fmt.Printf("nilFoo is NOT nil.") } v = nilFoo if v == nil { fmt.Printf("v is nil\n") } else { fmt.Printf("v is NOT nil\n") } Try online This prints: nilFoo is nil. v is NOT nil. On surface level, this is wrong: t is a nil. We assigned a nil to v but it doesn’t equal to nil? How to check if interface{} is nil of any pointer type? func isNilPointer(i interface{}) bool { if i == nil { return false // interface itself is nil } v := reflect.ValueOf(i) return v.Kind() == reflect.Ptr && v.IsNil() } type Foo struct { } var pf *Foo var v interface{} = pf if isNilPointer(v) { fmt.Printf("v is nil pointer\n") } else { fmt.Printf("v is NOT nil pointer\n") } Try online Why There’s a reason for this perplexing behavior. nil is an abstract value. If you come from C/C++ or Java/C#, you might think that this is equivalent of NULL pointer or null reference. It isn’t. nil is a symbol that represents a zero value of pointers, channels, maps, slices. Logically interface{} combines type and value. You can think of it as a tuple (type, value). An uninitialized value of interface{} is a tuple without a type and value (no type, no value). In Go uninitialized value is zero value and since nil is an abstract value representing zero value for several types, it makes sense to use it for zero value of interface{}. So: zero value of interface{} is nil which is (no type, no value). When we assigned nilFoo to v, the value is (*Foo, nil). Are you surprised that (no type, no value) is not the same as (*Foo, nil)? To understand this gotcha, you have to understand two things. One: nil is an abstract value that only has a meaning in context. Consider this: var ch chan (bool) var m map[string]bool if ch == m { fmt.Printf("ch is equal to m\n") } Try online This snippet doesn’t even compile: Error:./prog.go:8:11: invalid operation: ch == m (mismatched types chan bool and map[string]bool). Both ch and m are nil but you can’t compare them because they are of different types. nil != nil because nil is an abstract concept, not an actual value. Two: nil value of interface{} is (no type, no value). Once you understand the above, you’ll understand why nil doesn’t compare to (type, nil) e.g. (*Foo, nil) or (map[string]bool, nil) or (int, 0) or (string, ""). Bad design or inevitable consequence of previous decisions? Many claim it’s a bad design. No-one describes what a better design would look like. Let’s play act a Go language designer. You’ve already designed concrete types, you came up with notion of zero value and created nil to denote zero value for pointers, channels, maps, slices. You’re now designing interface{} as a logical tuple of (type, value). The zero value is obviously (no type, no value). You have to figure how to represent the zero value. A different symbol for interface{} zero value Instead of using nil you could create a different symbol e.g. zeroInteface. You could then write: var v interface{} var v2 interface{} = &Foo{nil} var v3 interface{} = int(0) if v == zeroInteface { // this is true } if v2 == nil { // tihs is true } if v3 == nil { // is it true or not? } Is this a better design? I don’t think so. We don’t have zeroPointer, zeroMap, zeroChanel etc. so this breaks consistency. It sticks out like a sore zeroInterface. And v == nil is subtle. Not all values wrapped in an interface{} have zero value of nil. What should happen if you compare to (int, 0) given that 0 is zero value of int? Damn the consistency, let’s do what user expects You could ditch the strict logic of nil values and special case the if v == nil for interface{} to do what people superficially expect to happen. You then have to answer the question below: what happens when you do if (int, 0) == nil? The biggest issue is that you’ve lost ability to distinguish between (no type, no value) and (type, nil). They both compare to nil so how would you test for (no type, no value) but not (type, nil)? It doesn’t seem like a better design either. Your proposal Now that you understand the problem and seen two ideas for how to fix it, it’s your turn to design a better solution. I tried and the above 2 are the only ideas I had. We are boxed by existing notions of zero values and using nil to represent them. We could explore designs that re-think those assumptions but would that be Go anymore? It’s easy to complain that something is a bad design. It’s much harder, often impossible, to design something better.
I signed up for Hinge. Holy shit with the boosts. How does someone who works on this wake up every morning and feel okay about themselves? Similarly with the tip screens, Uber algorithm, all the zero sum bullshit using all the tricks of psychology to extract a little bit more from every interaction in society. Nudge. Nudge. NUDGE. Want to partake in normal society like buying a coffee, going on a date, getting a ride, paying a friend. Oh, there’s a middle man now. An evil ominous middleman using state of the art AI algorithms to extract just a little bit more from you. But eventually the market will fix this, right? People will feel sick of being manipulated and move elsewhere? Ahhh, but they see that coming long before you do. They have dashboards. Quick Jeeves, tune the AI to make people feel less manipulated. Give them a little bit more for now, we have to think about maximizing lifetime customer value here. Oh the AI already did this on its own? Jeeves you’ve been replaced! People perpetually on the edge. You want to opt out of this all you say? Good luck running a competitive business! Every metric is now a target. You better maximize engagement or you will lose engagement this is a red queen’s race we can’t afford to lose! Burn all the social capital, burn all your values, FEED IT ALL TO MOLOCH! Someday, people will have to realize we live in a society. What will it take? A complete self cannibalization to the point you can’t eat your own mouth? It sure as hell isn’t going to be people opting out, that’s a collective action problem you can’t solve. Democracy, haha, you think the algorithms will let you vote to kill them? Your vote is as decoupled from action as the amount Uber pays the driver is decoupled from the fare that you pay. There’s no reform here, there’s only revolution. Will it simply be a huge financial collapse? Or do we need World War 3? And even World War 3 is on a spectrum. Will mass starvation fix this? Or will the attitude of thinking it’s okay to manipulate others at scale persist even past that? He’s got his, and I’ve got mine… If you open a government S&P 500 account for everyone with $1,000 at birth that’ll pay their social security cause it like…goes up…wait who’s creating this value again? It’s not okay. Advertising is not okay. Price discrimination is not okay. Using big data, machine learning, and psychology to manipulate others at scale is not okay. But you aren’t going to learn this lesson until you have fed a huge majority of your customers to Moloch. Modern capitialism is wireheading. Release the hypnodrones. How many cans of Pepsi did you want them to consume an hour again?
I've never seen so many developers curious about leaving the Mac and giving Linux a go. Something has really changed in the last few years. Maybe Linux just got better? Maybe powerful mini PCs made it easier? Maybe Apple just fumbled their relationship with developers one too many times? Maybe it's all of it. But whatever the reason, the vibe shift is noticeable. This is why the future is so hard to predict! People have been joking about "The Year of Linux on the Desktop" since the late 90s. Just like self-driving cars were supposed to be a thing back in 2017. And now, in the year of our Lord 2025, it seems like we're getting both! I also wouldn't underestimate the cultural influence of a few key people. PewDiePie sharing his journey into Arch and Hyprland with his 110 million followers is important. ThePrimeagen moving to Arch and Hyprland is important. Typecraft teaching beginners how to build an Arch and Hyprland setup from scratch is important (and who I just spoke to about Omarchy). Gabe Newell's Steam Deck being built on Arch and pushing Proton to over 20,000 compatible Linux games is important. You'll notice a trend here, which is that Arch Linux, a notoriously "difficult" distribution, is at the center of much of this new engagement. Despite the fact that it's been around since 2003! There's nothing new about Arch, but there's something new about the circles of people it's engaging. I've put Arch at the center of Omarchy too. Originally just because that was what Hyprland recommended. Then, after living with the wonders of 90,000+ packages on the community-driven AUR package repository, for its own sake. It's really good! But while Arch (and Hyprland) are having a moment amongst a new crowd, it's also "just" Linux at its core. And Linux really is the star of the show. The perfect, free, and open alternative that was just sitting around waiting for developers to finally have had enough of the commercial offerings from Apple and Microsoft. Now obviously there's a taste of "new vegan sees vegans everywhere" here. You start talking about Linux, and you'll hear from folks already in the community or those considering the move too. It's easy to confuse what you'd like to be true with what is actually true. And it's definitely true that Linux is still a niche operating system on the desktop. Even among developers. Apple and Microsoft sit on the lion's share of the market share. But the mind share? They've been losing that fast. The window is open for a major shift to happen. First gradually, then suddenly. It feels like morning in Linux land!
