Inspired by Jedda’s Postroll, here is an incomplete list of blog posts that I’ve read and enjoyed in the last 3 months. This list refreshes daily.
If you find any of these posts interesting, I suggest that you give them a follow!
Emulating dependent-types is fun indeed! I haven’t played with Zig, but it’s super interesting how you can do work in comptime before the rest of the compilation and type checking procedures kick in.

I try not to think about the permanance of my writing. It’s true that anyone can see my blog posts from 10 years ago. Even the ones that frankly aren’t well written. It’s also easier to write mainly technical blog posts since those age better than opinions.
Though at the same time, we should accept that we are not static as humans. Just because I wrote something a year ago doesn’t mean I still hold those opinions today.

I agree that for continental flights, going through security and navigating the airport takes a good chunk of time. Currently I’m spoiled because I live by a small regional airport where I can go through security in 20 minutes.
Unfortunately, I don’t think an airplane manufacturer can fix this issue. Back in 2023, I went through customs at JFK. After waiting 45 minutes in line, I was graced with a 15 second interaction with the officer where he checked my passport.
Could this process be faster? Probably, but don’t ask me how.

Why 'alias' is my last resort for aliases by
Some people have large dotfile repositories. I am unfortunately not one of them. Generally, I keep my configurations to a minimum. However, I do have some custom scripts I like to use. I keep these in ~/.local/bin.
I like the idea of using scripts instead of aliases. It makes it easier to extend in the future as well.

Paper by
I think a LOT through paper. Whenever I’m pondering a new research idea or working through a mathematical proof, I’m using paper. Not to say that I haven’t tried using other mediums. However…
- I don’t like the brainstorming experience on my iPad.
- If I’m working collaboratively, then I prefer using a whiteboard. Though when it comes to thinking by myself, I always gravitate back towards using paper.
This post mentions how paper does not work well as a means of information storage. I agree so much with this notion, that I often don’t keep paper for longer than a few days. If I want to store the information, then I will take the time to digitize it.

Don’t fear silence in a conversation. In fact, this post shows us how it can be a useful tactic during hard conversations. Personally, I agree. You shouldn’t feel pressured to come up with quick responses to fill the air. Additionally, don’t feel afraid to call a time-out. It’s better to have time to collect your thoughts than to say something you’ll regret later.

tl;dr I ran a marathon at the weekend and it was hard by
I don’t commonly run and I don’t currently dream of doing a marathon, however, this was a very insightful read! Running 26 miles on average burns more calories than a typical human consumes in a day. No wonder one has to train for months to do this! It’s a test of how efficient your body is at storing and exchanging energy.
If you’re thinking about training for a marathon, definitely check this post out.

Ruben made two points that I resonated with: turning off notifications (which he previously wrote about) and decoupling functionality from his smart phone.
Personally, I disable most notifications when it comes to social media, RSS feeds, and email. I don’t like getting notified in general, and opt to instead check those manually a couple times a day.
In terms of decoupling, a big one for me is that I don’t have the wallet feature enabled on my phone. Is this inconvinient for me? Not really, most of the time. Except for last summer, when I lived in San Jose, California.
In the bay area for a summer internship, I decided that I would get to work via public transit. It was a decision for sure. It took me an hour and two bus rides to get to the office. For comparison, driving took only 11 minutes, and walking would’ve taken 3 hours.
Though I’m not here to complain about my life decisions, I’m here to complain about the Clipper system. Keep in mind, that this is a point in time complaint. For all I know they’ve improved since I left. For likely historical reasons, the San Francisco Bay Area has more than one transit system. There’s the BART, Caltrain, MUNI, VTA, SMART, AC Transit, and I’m sure more that I’m not remembering (See Wikipedia article). Instead of maintaining accounts for each of these, the idea is that you have a Clipper account, and they will manage paying out all the individual travel agencies for you.
In order to get a physical card, I had to visit a physical travel office. Okay, that’s fine. Now the bigger question is, how do I refill the card? What I’ve learned after trial and error is that I can pay online, visit a physical MTA office, a select few train stations, or Walgreens. I’m not against filling up the card online, so I decided to first try that out.
Imagine, you’re low on your card. You primarily rely on the public transit to get around, so you would expect the money to be available immediately right? Haha no, actually it took about three days for the money to get loaded. To make things worse, during those three days they’ll email you every hour saying that they’re processing your order.
Ultimately scarred by that experience, I decided to pay for the monthly VTA pass. Keep in mind that this only gave me unlimited rides for the VTA. I decided to go this route since the two busses I used to get to and from work was under that system. For the other ones, I had to keep track of my balance and opportunistically fill it up whenever I happen to be by an area where I can do that.
All that to say, they heavily promoted the mobile Clipper experience. Maybe life would’ve been easier if I accepted that. However, I couldn’t have both a physical Clipper card and a mobile one. What happens if your phone dies? Walk three hours home?

The Fifth Kind of Optimisation by
I like Laurence’s five kinds of optimizations. I wonder if he has any advice on the order we should pursue these in. For example, try a different data structure before adapting the algorithm, and try to adapt the algorithm before rewriting it in parallel.
It’s definitely more difficult to write good multiprocessing code. Even when working with a high-level abstraction like Python, I have to think about how a multiprocessing pool behaves differently depending on the operating system. On the side, I’m rewriting how one of my tools handles parallelism. Luckily, this blog post reminds me that conditional variables exist! Time to remove the busy-waiting loop.

The case against conversational interfaces by
This is a thought piece on the role of conversational interfaces. It’s fun to recall the days where voice assistants were the hot craze. I used an Alexa device for about a year, I also tried using Google Assistant. However at the end of the day, I mostly only used them to set timers on my phone.
Nowadays, I don’t even do that. Whenever I do laundry, I pull out my phone, navigate to the clock app, and hit one of the preset timers I have ready to go. That doesn’t mean that these technologies are useless, just that these aren’t the right use cases for me.
I agree with this post that LLMs thrive in exploratory work. They help get past the blank screen problem where the ideas start flowing. I currently don’t see them as meta-assistants for me anytime soon. Not because I don’t think they’ll be easily integrated into different web services, but because I find this a hard sell from a privacy perspective. While part of me thinks it’s cool to have a computer assistant that knows all about you, at some point these companies will need to start monetizing these technologies…

We Won't Save the Planet by Shrinking by
Every day comes with its high and lows. Especially if you keep up with the news. However, I try to keep an optimistic view of the long term. This post talks about how as humans we don’t just consume resources, but we solve problems. I agree! Even though our newer technologies require more power currently, we’ve been finding ways to make generation and consumption more efficient.

Why developers question everything by
Building software comes with a lot of tradeoffs. I feel like we have to question the intention behind it to make the right calls. I’ve never done a bathroom renovation before, but I feel like there are fewer variables that a customer wants to tweak and the use cases behind a bathroom stay largely the same. If I asked to move my toilet to inside the tub, I would sure hope that I get some pushback as to why.
Though why do software developers question everything? Go and read the post to find out :)

Maintaining any piece of software for long enough teaches you that every so often you need to do work which doesn’t immediately translate to new features. Of course there’s a fine line between refactoring to accomedate this year’s JavaScript framework versus extendability in the long run. However, Rust has proven itself to reduce many bugs common in memory unsafe languages. I agree with this post that it’s good to make this transition in the long run, even if we start with coreutils first to build out the infrastructure.

Insightful read on the incentives that we have today for information production and how especially for copyright some may need to be considered in the age of LLMs.
Before this post, I haven’t thought too deeply on the notion of trade secrets. However, it makes sense to me now. We definitely don’t want to live in a society where people are attempting to steal secrets from each other all the time. It’s more productive as a society to compete by innnovating.

Deep dive on assertions and their use in identifying issues within software. Honestly, I didn’t know that large projects like Firefox and LLVM have thousands of assertions enable and active when people run their code. It makes total sense, why allow for undefined behavior? If something seems out of whack, crash out and let user reports help guide developers to fixing the underlying bugs.

Retrieval Augmented Generation by
I’ve been playing around recently with local LLMs using Ollama and Open WebUI. I find it amazing that as hobbyists, we can self-host a service that’s comparable to ChatGPT and Claude without needing to purchase the latest GPU or give up our privacy. This blog post talks about Retrival Augmented Generation (RAG), a feature that’s common in these platforms which allows a LLM to answer queries based on some set of documents.

How great is the Send Later feature? by
The Send Later feature is interesting because it puts the control on the sender on when they want the receiver to get the notification. It makes sense, I wouldnt want to be bothered very early in the morning. Though I wonder, wouldn’t it be better if the receiver used finer notification controls? Well it turns out, we already have that ability. For example, on Android there’s the “Do Not Disturb” feature which lets you control when and whom you receive notifications from. The Apple ecosystem equivalent is Focus modes. Though I don’t think that these features are widely adopted among the people I communicate with. So ultimately, that leaves us with Send Later.

The Impact of Digital Authorship by
Like Ben, I also am able to type out faster than I can think. When writing, this turns into a back-and-forth: think for a minute -> quickly type out thoughts -> think again. I also generally context switch between drafting and editing when writing. I’m not entirely convinced that it’s unproductive to do so, but maybe it has to do with the type of writing we’re talking about. For me, when it comes to technical long-form writing, I like to outline via bullet points the concepts I want to hit, and then work towards crafting sentences that meet all those points.

Post-Quantum Cryptography in February 2025 by
In my life, I hear smattering of quantum updates. I’m currently studying at a university with a quantum computer, and I’ve worked at IBM’s Thomas J. Watson Research center which houses plenty of quantum research.

The opinions shared in this piece still hold three years later. For the most part, cryptocurrencies today are too volatile to use as a means of exchange from day-to-day. Additionally, trust and ambiguity are useful features in our society that we should seek to keep and not eliminate. See his post for examples of these claims. The author states that winners in this space will address these issues while also enabling a modern way of handling money. Stablecoins I feel are a step in this direction. They address the volatility issue by pegging to an existing stable asset. They don’t, however, seek to address trust and ambiguity. Imagine the efficiencies we can unlock when we’re able to have trusted actors in the system.

I have a similar experience to this piece. One day my car started making a cylic mettalic noise when I was driving. I took my car to the mechanic and it turned out that part of the underbody got bent out of place. The technician bent it back and I went on my merry way.
I agree that it’s easy to overcomplicate things. Especially when it comes to complex technologies like a car. Start simple first, and if needed, work your way into complication.

Smuggling arbitrary data through an emoji by
I heard of watermarking text and zero-width characters before, but this provides a deeper dive (with code!) on how you can hide data in Unicode.
Since this technique relies on variation selectors, you cannot hide a message in any arbitrary unicode character. However, it seems that it works for all the ASCII characters and many emojis. I’m not sure if I would trust hiding it in an emoji though, since new ones are added regularly.

On not taking it personally by
Commonly, active software projects evolve with time and with the demands of their users. This is different than a lot of creative professions, where outside of preservation techniques, the work stays largely unmodified. Even so, it’s easy to feel an attachment to the coding work we’ve done, and become upset when it’s no longer needed. Joel provides a new perspective in this post. He reminds us that we’re paid to solve problems, and not for the lines of code we write.

Can We Retain the Benefits of Transitive Dependencies Without Undermining Security by
As this post describes, the computer process is an excellent abstraction in which programs cannot affect each other. However, we don’t have similar mitigations within the process itself. As more and more of the code that runs an application comes not from the author themselves, but in their dependencies and their dependency’s dependencies; it becomes important for us to know how to prevent a rogue actor from stealing sensitive information. This post presents some potential solutions, and I look forward to seeing how this area progresses.

Maximizing Communication, not Traffic by
As a reader of many blogs on the Internet, I imagine that I take inspriration and absorb the styles of others in my own writing. I haven’t really sat down and thought about the intentions others have when writing. However like Jeff, I’m also among the minority that doesn’t monetize their website. Therefore, the tactics that some writers use to captivate attention and increase the amount of time that a reader spends on their website doesn’t necessarily apply to me. It’s a great reminder to be mindful and think about the style of communication that I’m trying to cultivate on this website.

Nobody Gets Fired for Picking JSON, but Maybe They Should? by
Wow. From a human-readable standpoint, I enjoyed working with JSON. However, when it comes to using it for inter-process communication, I always felt that it didn’t quite cut it. I mostly thought of this issue in terms of data efficiency, however, it turns out that the problem goes deeper than that. This post shows that since many details are left to the implementors, there are JSON (de)serializers out in the wild today that will result in data loss when parsing integers with more than 16 digits. Some credit cards have more than 16 digits.
