@phanpy by @cheeaun is a great client, and a great piece of software in general. It is so well done, it has become something of an inspiration to me to write great software. I can't help but sponsor it on Github.

I've trying to make it my daily driver everywhere, replacing @ivory on my laptop and @trunksapp on my phone. It's been working great except some small things: the scrolling of timelines seems a bit stuttery as compared to Ivory, the popout panes disappear when I change the browser zoom level, there is no quick way to change the columns unlike Ivory, and some other minor things. I hope all of this is worked out in time so that I can shift to it completely.

A poll: Since I spend so much time on / , I'm curious what y'all think is the best indicator for the quality of a post here:

Number of replies/comments.
Number of boosts/reposts.
Number of favourites/likes.
A combination of the above. Please comment.

Is max HR determined automatically by Garmin watches reliable?

I've been consistently for last one year (ran over 500km) and my watch has been increasing my detected max heart rate slowly. Last week it reached 202 bpm, and that has me a little worried because I'm not exactly a young man (almost 40 now). Since my workouts are heart rate based, they have been getting harder too. Though I must say, I feel less tired than a year ago.

Has anyone else experienced this? Is it safe to follow the max HR determined by the watch?

I have been using Reeder on my laptop as my reader app backed by for a while now. Recently, I found myself often clicking away from Reeder to the original posts in the browser.

I realised that most of the blogs I follow do not need sanitisation as done by feed readers because they are usually well-designed and do not contain ads. In fact, some of them are great looking, and have their own unique looks. I noticed that I prefer reading them in the browser, in their full glory, with their different styles, instead of all of them looking same black-and-white minimal-styled text in the reading pane of Reeder.

So, I went out looking for a feed reader that manages subscriptions like usual, but instead of having it's own reading pane, opens the articles in a side-by-side browser pane. And I found NONE.

So I hacked my own using some custom CSS and JS added to the Miniflux UI. Learn about it in my latest note: notes.abhinavsarkar.net/2024/c

I have always been a proponent of websites publishing for their content. My own website has feeds for almost everything on it (abhinavsarkar.net/feeds/). But till now, it only published latest few items in each .

I also extensively use feed readers to read many feeds. I noticed that while subscribing to people's feeds, I find myself looking at their older posts published years ago, and often find interesting stuff in them. So I've decided to remove limits from the feeds on my website, so that it shows all my posts ever.

I hope people find something interesting in my old posts as well.

JSON is probably the most used standard file format for storing and transmitting data on the Internet in recent times. It has a simple syntax with only four scalar data types and two composite data types. So, writing a parser for is a great exercise for learning the basics of parsing.

I've been reading the in Small Pieces book, and it has helped me put names to a lot of concepts that I knew about Lisps and programming language design/implementation in general. It also provides a great historical perspective to , especially by mentioning all approaches that were tried but abandoned.

But other than being very very verbose, I find it hard to understand because it keeps changing the model of the interpreter every chapter. It starts with using Alists to model environments, then uses objects in the next chapter for the same, and in the next one, switches to using closures.

I get that it does this to showcase all possible ways of modelling an interpreter in Lisp, but it is quite disorienting to me as a reader.

But I can't say that the author didn't forewarn me. This is literally the fourth sentence of the book:

“To explain these entities, their origin, their variations, this book will go into great detail.”

It is a decent read, though the language feels a little outdated. It is translated from French so that may be the reason of the overly magniloquent language.

I learned to escape the imperative programming languages, which in turn got me interested into and . Turns out, most of the real-world compilers are written in C and C++, so here I am back at square one.

After years of avoiding it for decades, I taught myself in the last couple of weeks. So anyway, does anyone want me to write a series of posts about making a interpreter (github.com/kanaka/mal) in C++?

5 ↩️ 2 🔁 2 ♥️ via Ivory for Mac

I've been writing for about a month now, and even though I have to lookup the docs very very often, the hardest thing I find is to keep track of lifetimes of objects, references and (smart) pointers. Using references and smart pointers gives an illusion of almost having automatic garbage collection. But one mistake of not tracking the lifetime correctly, and the object disappears, causing null pointers and segmentation faults.

I don't know if I'm running into these issues because I'm a noob or because that's how C++ programming goes. Hopefully it will become more intuitive with time.

The second biggest problem that I have faced with writing a PL implementation in is the lack of immutable data structures. I keep modifying the AST by mistake while walking over it. This is made much worse by the fact that I'm trying to implement a with immutable data structures (much like ).

When I copy container data to preserve the old versions, I feel bad because of the performance implications. There is no easy way to share internal data between different versions of same data structures (AKA persistent data structures). Maybe there is a library that can help me all this.

I finished Make A in C++20 in about 2600 lines of code. I learned a lot about modern and managed to write the whole interpreter without writing a single C-style macro or pointer arithmetic or type casting.

Compared to my usual choice , C++ is way more verbose. I feel I can write the same interpreter in (idiomatic) Haskell in less than 800 LOCs. But it’ll probably be much slower.

Some time later in the year, I want to attempt writing a compiler for MAL in Haskell via QBE.

Today morning while I was brushing my teeth, I had a sudden realisation that the word “innings” is opposite of the word “outings”. It's just that we are indoor living people now, so we do more outings than innings these days. If we were people who spent most of the time outside, say in a forest foraging for food, and went to live in houses for winters, we’d call it "going for an inning”.

I just made my + installation on macOS self-contained by making it so that running `nix-shell` anywhere uses the Nix package version in use by Home Manager, thereby sharing packages between the Home Manager installation and system-level Nix shells. I even deleted the `nixpkgs` channel after doing this because it's not needed anymore.

All I had to do was to add this shell hook:

```
shellHook = ''
export NIX_PATH=$HOME/.hm-nixchannels;
mkdir -p $NIX_PATH;
ln -f -s ${pkgs.path} -T $NIX_PATH/nixpkgs;
'';
```

and this session variable:

```
home. sessionVariables = {
NIX_PATH = "$HOME/.hm-nixchannels";
};

While trying to upgrade fantastic.earth to 4.2.1 today, I accidentally ended up upgrading the service as well because both of them were using the same pinned channel. Mastodon upgrade worked fine but Bookwyrm refused to build because of some Python packaging issues.

So I just copied the previously working channel for Bookwyrm and changed its config to use the same, upgrading only Mastodon.

Doing these kind of things would be so cumbersome if I had not been using NixOS.

I also managed to wipe out the whole Nix store while trying to figure out the Bookwrym build issue (by running garbage collection). But no problem, I just ran the build again, and everything was back to how it was.

So, the point I'm trying to make here is, use NixOS for setting up your servers. The isolation and reproducibility (and composability) is worth learning the complex language.

0 ↩️ 0 🔁 1 ♥️ via Ivory for Mac

The upgrade went without a hitch, as have all previous ones. shines here as well because all the upgrade related changes are handled by the NixOS service code written and tested by expert maintainers, instead of random admins like me.

A test for a new feature I wrote started failing with different error diffs in every run. I was perplexed by it become all of my code is supposed to be deterministic, no random values created or used anywhere. After poking all over the code base and breaking my head over it for a day, I realized that the non-determinism comes from the hashmaps I used in my code. This is because iteration over hashmaps is non-deterministic, causing the output to be possibly different every time. 😩

I've been trying to build a personal for for myself for some time and I've got a basic version working. Here's how it works:

1. Fetch posts in my home timeline for last 24 hours.
2. Apply my Mastodon filters on them to remove unwanted posts.
3. Remove private posts.
4. Remove posts that I have liked, boosted or replied to.
5. Remove foreign language posts.
6. Fetch like, boost and reply counts for the posts from their origin server.
7. Partition posts into boosts and non-boosts, and apply next steps for each partition separately.
8. Assign scores to posts using this formula:
`score = geometric_mean(like_count, boost_count, reply_count) / square_root(follower_count_of_poster)`
9. If a post contains any of my specified favourite tags, increase its score by multiplying it by a constant factor (I use 1.2).
10. If a post is from any of my specified favourite accounts, increase its score by a constant factor (I use 1.2).

1/2

1 ↩️ 0 🔁 2 ♥️ via Ivory for Mac

continued …

11. Reduce the scores of each post by a factor of `power(2, (time_now - post_create_time)/half_life)` where `half_life` is something like 6 hours. This causes older posts to have lower scores.
12. Group posts into threads they are part of, if any. Then select the highest scored post from each thread. This prevents posts from popular threads from taking over.
13. Sort posts by their score and select top 10% of posts.
14. Randomly select some posts from the bottom 90% of posts.
15. Render these posts as a webpage and serve on internet.
16. Run this entire process twice or thrice a day, and read the rendered webpage, interacting with the posts.

The initial inspiration for this algorithm came from @MattHodges's work (steps 1–4, 7–8, 13, 15) that I improved upon (steps 5–6, 9–12, 14, 16).

I have few more ideas like reducing the scores of posts with certain tags, but the current algorithm works pretty well for me. I'm also thinking about how to make it near-realtime instead of a batch process.

Finished reading "Type Systems for Memory Safety" borretti.me/article/type-syste by Fernando Borretti. It is a comprehensive review of various type system features across different that are used to enforce (varying degrees of) memory safety at compile time.

As expected, it talks a lot about because Rust is probably the most used PL with compile time memory safety, but it features other languages like Ada, Val and Austral as well.

An interesting read if you are interested in .

Read noidea.dog/glue by @whereistanya and found this:

> In fact, doing glue work too early can be career limiting, or even push people out of the industry.

This reminds me of the time when I was the only senior (and glue) engineer in an important team of a big e-commerce company in India. I was coordinating seven projects between multiple teams, seting up the CI process, doing code reviews, mentoring multiple people, writing design documents etc.

At the end of the year, my manager gave me a bad review saying I didn't have enough code contribution. Ironically, that was probably the year when I had most impact on a company’s bottom-line. But the bad review after such hard work broke my heart. I switched to a different job soon after. It has been the shortest work stint of my whole career (1.25 years).

It's great to be a glue engineer if that's what you love doing. But it is very important to make sure that your contributions are counted.

This post led me to explore clients with unconventional interfaces and I found some interesting one:

– Ebou (terhech.de/ebou) has the layout of a desktop messenger: leftmost column shows account names that have posted recently; clicking on them shows recent posts by them in an adjacent column, and clicking on the posts shows their conversation threads in the next column.

– Tut (tut.anv.nu) is a terminal UI client inspired by Vim, the code editor. It supports Vim like keyboard navigation as well.

– Macstodon (github.com/smallsco/macstodon) is a Classic Mac OS app, and looks kind of like old-school IRC clients.

– Stomp (stomp.social) run on Apple watch. You can scroll timelines or mention or lists but only one post at a time.

– Mastotron (github.com/mastotron/mastotron) completely eschews the concept of linear timelines and instead presents posts as graph of connections.

If you know any other such unconventional clients, please feel free to add to this thread.

Forgot to mention Toot.

– Toot (github.com/ihabunek/toot) is a CLI client, which provides you commands to interact with Mastodon. For example, to see the recent posts by me, you can run `toot timeline -1 -a abnv@fantastic.earth`. You can also use it to automate interactions. For example, to follow accounts that recently made posts with the Haskell tag on the discuss.systems instance, you can run: `toot timeline -1 -i discuss.systems -t Haskell | grep -oP "@[^ ]*@[^ ]*" | sort -u | xargs -n1 toot follow`. I love it!

fantastic.earth went down for few hours today because decided to build the new nodejs package from scratch on the server. And that ate all the CPU and memory, causing the server to become unresponsive. I need to figure out a remote building strategy for Nix so that this doesn’t happen again.

@arun and I have finally succeeded in setting up the remote build for the fantastic.earth setup.

We ran into an issue where Nix runs a command on the remote machine with sudo, but we didn't want to give sudo permissions to the remote build user. It turns out, sudo is not really needed and the build works fine without it. So @arun hacked up a no-op sudo substitute, which when put in the $PATH satisfied Nix and the build worked. ¯\_(ツ)_/¯

Finally, no more build caused downtimes!

Trying out the client @phanpy for the first time:

— Rounded corners everywhere, which is a little too much for my taste.
— I love the Boost carousels, and clean post threading, and post detail popups.
— The light mode somehow looks better than the dark mode, which is very unexpected because I use almost everything in dark mode.
— Really missing having keyboard shortcuts for navigation and actions.

I'm going to try it for a couple of days to see how it compares to my current client @elk.

I'm guessing that's because of the way it groups boosts.

Spent the day thinking about how to compile my small language with coroutines to Javascript, without actually doing a CPS transform of the AST. I think I may have a solution involving yield* and setImmediate. Proof of concept yet to be done.

Last week I spend almost three days to figure out a bug in my code. And the final fix was a single line change. It was both infuriating and exhilarating at the same time.

I really like reading things on my Kindle. I wish there was an easy way to read all these interesting blog posts on it. Maybe a service to which I can send URLs, or points them to an RSS feed and it sends me a book for them.

Is it me or this year's seems too heavy on automata, game plays and simulations? I was hoping for more parser and interpreter related problems.

It worked! Couldn't figure out how to patch the service, so I copied the file, made the change in it, and replaced the service module with the copied one.

The new Arctic Monkeys album is even more mellow than the previous one. Maybe I'll grow to like the new AM, but for now I miss the old one.

TBH, I like the albums in the middle the most, around early 2010s. When they started out to mellow out, but were still Rock like.

I use the bookmarking feature on as a read-later list to mark interesting posts that I want to read in depth, but I can't at the moment while scrolling the timeline. After reading them later, I remove the bookmark. Am I doing it right?

Saw someone's toot about trying to learn how to drive a geared car (or drive stick, as they say in USA). And here I am driving a geared car, and hating it, being anxious all the time about missing gear changes and driving in wrong gear. I'd love to not drive stick, but I can't buy a new car right now.

I like solving #AdventOfCode problems with one liners, and I cannot lie (split into multiple lines below for your convenience):

solve n input =
(+ (n - 1))
. fst
. fromJust
. find ((== n) . length . snd)
. zip [1 .. ]
. map nub
. transpose
. map (flip drop input)
$ [0 .. (n - 1)]

The upgrade to 22.11 worked almost smoothly! I had to
— disable a python service because of "infinite recursion encountered" error (I wanted to disable it anyway),
— change config of one service, and
— fix dependencies of two services.

I've found and followed so many interesting people from different walks of life on Mastodon in the last one week. I don't think this would be possible on the Twitter of now.

: Mastodon creates and exposes a public key for each user at <instance-url>/users/<username>.json.

I wonder if that can used for signing things we put on internet.

/ protip for people an Nginx server: add the following line to your Nginx virtual host config so that you can be found by a search like @me@yourdomain.com:

rewrite ^/.well-known/webfinger.* https://<your-mastodon-host>/.well-known/webfinger?resource=acct:<your-username>@<your-mastodon-host>? permanent;

For example, my server at abhinavsarkar.net has this config:

rewrite ^/.well-known/webfinger.* https:// fantastic.earth/.well-known/webfinger?resource=acct:abnv@fantastic.earth? permanent;

(Minus the space after https://. Mastodon converts it to a link so I had to put the space.)

So you can find me in Mastodon search by @me @abhinavsarkar.net

(Minus the space between. Mastodon automatically convert it to the resolved account so I had to put a space between.)

I knew about for at least a few years but I was afraid that the clients would be unpolished. Now that I'm here, I must say I am pleasantly surprised by how good all Mastodon apps are. Both Android and iOS apps are easy to use and reasonably smooth. Though I don't use the web UI much, it's pretty good as well.

Still trying to get Bridgy Fed working on my website. I can see my website on Mastodon but I don't see any posts, neither am I able to follow it. I guess it's time to look at the Nginx logs.

I uninstalled Reddit, Hacker news and Twitter apps from my phone so Mastodon is my only friend now.

My levels of yak shaving:

1. Get on Mastodon.
2. Enable Activity Pub for my website using Bridgy Fed.
3. Embed h-card on my website's home page.
4. Add support for transclusion in Markdown files.
5. Modify Mustache templating code to add support for chasing dependencies using Shake build system.

Fortunately, the stack has unwound now, for I am posting this on Mastodon, and my website is Activity Pub enabled.

So I got on Mastodon. Next, find people to follow.
