The goal was to see how it handles rendering a standard HTML page compared to a modern web browser. The Setup I asked ChatGPT 5.1 Thinking to create it with this prompt Create a html for a mock business profile landing page about independently owned convenience store. It should be 1 file contain all the html js css It happily produce 1700 line length HTML page for it.https://adhikasp.my.id/posts/2025/03/poe-phrecia/Sat, 01 Mar 2025 18:39:00 +0700https://adhikasp.my.id/posts/2025/03/poe-phrecia/Path of Exile Legacy of Phrecia has been going on for some time, it introduce all new ascendancies so let’s see if what new build stands out.

LLM + function calling + ReACT is the usual way. But it can only call predefined functions with predefined arguments. But smollagents do the function calling as part of code exection. It have Python runtime as part of the agent chain of thoughts. So it can call and compose the functions, do iteration, and pass larger amount of data between call (pass the whole pandas dataframe, for example).https://adhikasp.my.id/notebook/alfamart-vs-indomart/Sun, 09 Feb 2025 15:12:17 +0700https://adhikasp.my.id/notebook/alfamart-vs-indomart/Alfamart and Indomart are two of the most popular convenience stores in Indonesia. For thought experiment, lets try to explore the data that we can get from OpenStreetMap about it. Do note though that OSM data is not always complete and up to date, so the results might not be 100% accurate. If you notice specific place are missing, do try to add them on OSM! Pull list of minimarket To do this, we are using osmnx library, which simplify the query process to the OpenStreetMap database, and we got a tidy GeoDataFrame ready to process further.https://adhikasp.my.id/link-blog/jupyter-notebook-in-hugo/Sun, 09 Feb 2025 12:53:37 +0700https://adhikasp.my.id/link-blog/jupyter-notebook-in-hugo/Very handy guide on how to render Jupyter Notebook in Hugo.

It works by pulling the video transcript as part of the LLM inference. The problem is, YouTube puts IP blocking on their public API, making the code work in my dev machine but not in the deployed production server that I have in fly.io. This is a common issue when using cloud providers, as their IP ranges are often blocked by services to prevent abuse.https://adhikasp.my.id/link-blog/simon-willison-link-blog/Sat, 08 Feb 2025 00:00:00 +0000https://adhikasp.my.id/link-blog/simon-willison-link-blog/Simon Willison shares his thoughts on maintaining a link blog - a curated collection of interesting links with personal commentary. What resonates with me is how link blogs serve dual purposes: they’re both a personal knowledge management tool and a way to share discoveries with others. Key points from Simon’s article that I find compelling: Link blogs help build a personal archive of interesting content They encourage active engagement with content through commentary The practice combines personal note-taking with public sharing It’s a lightweight form of blogging that’s easier to maintain than full articles This aligns perfectly with my goal of both keeping personal notes and sharing interesting findings with others.https://adhikasp.my.id/posts/indonesia-postal-code/Sun, 02 Feb 2025 00:12:17 +0700https://adhikasp.my.id/posts/indonesia-postal-code/Today, I watch a video from CGP Grey on postal code patterns. I was curious about the postal code pattern in Indonesia, so I decided to visualize it in Kodepos. I built it with help of Cursor. Lately I found it making producing code and exploring new ideas much more fun. As I can focus on what I want to do instead of how to do it and figuring out how to use this random Python library or trying to understand how pandas dataframe works.https://adhikasp.my.id/posts/reviving-blog-2025/Sat, 01 Feb 2025 20:38:06 +0700https://adhikasp.my.id/posts/reviving-blog-2025/Feels like writting, so I dig into my GitHub repostory and refound this old blog of mine. I have few different iteration of my blog. The first one is a WordPress blog that was part of high school IT subject. Then I think I create an static nginx based website, hosted on VPS. And this one, a Hugo site originally hosted on my homelab.

Because aspect is still new and experimental, many things around it is still untested. Also, not all bear in coala (read: none of them) support aspect. And it will be a long time before it happen. So I think it’s important to make the migration process became more easy. In this phase, I try to polish up feature so hopefully it will became more sane to be used.https://adhikasp.my.id/posts/gsoc/gsoc-phase-2-working-minimal-coala-aspect/Fri, 21 Jul 2017 00:00:00 +0700https://adhikasp.my.id/posts/gsoc/gsoc-phase-2-working-minimal-coala-aspect/This post is part of my GSOC journey in coala. In phase 2, my target is to make aspect-based configuration works. Maybe not with its full power and capabilities, but at least the core foundation must ready in coala codebase and prove that aspect could run. Starting from my previous phase, I have 3 crucial milestone to reach, which is: Intepret aspect-based configuration Passing aspects into bear Choosing bear based on aspects Even though the todo is short, I meet with miscellaneous supporting works, few surprising but interesting “bugs”, and design decisions.https://adhikasp.my.id/posts/gsoc/gsoc-phase-1-mid-automatic-star-import-expanding-on-autoflake/Sun, 18 Jun 2017 00:00:00 +0700https://adhikasp.my.id/posts/gsoc/gsoc-phase-1-mid-automatic-star-import-expanding-on-autoflake/This post is part of my GSOC journey in coala. In this week, I was writting a patch into autoflake for a new feature that could expand a wildcard import to specify each name that really was used in the code. Autoflake and how it work Short introduction. Autoflake is a tool for automatically remove unused imports, unused variables, and useless pass statemant from Python code. It was mainly dependent on pyflakes, a python code checker, which provide the analysis foundation to check for the faulty code.https://adhikasp.my.id/posts/gsoc/gsoc-bonding-understanding-current-coalas-aspect-code/Wed, 31 May 2017 00:00:00 +0700https://adhikasp.my.id/posts/gsoc/gsoc-bonding-understanding-current-coalas-aspect-code/This post is part of my GSOC journey in coala. Even though aspect project in coala still in its infancy, there are already exist a basic prototype of itself in coala codebase. Today, I’ll dive into these code and try to analyze the core part about aspect. Seek First to Understand, then to be Understood That is a quote from the 7 habbit of Stephen Covey. It is a habbit for social interaction, but idk, I’ll try to make some connection here because I feel like it.https://adhikasp.my.id/posts/gsoc/designing-coalas-aspect-configuration/Tue, 30 May 2017 00:00:00 +0700https://adhikasp.my.id/posts/gsoc/designing-coalas-aspect-configuration/This post is part of my GSOC journey in coala. With the emerge of aspect project in coala, come the need to redefine how configuration works and define various new parameter that should control how the aspect should run. Currently, the mockup for those configuration could be found on cEP-0005 and look like this 1[all] 2# Values can be added to inherited ones only, not within the section because 3# a configuration should describe a state and not involve operations.https://adhikasp.my.id/posts/gsoc/first-introduction-to-open-source/Fri, 12 May 2017 00:00:00 +0700https://adhikasp.my.id/posts/gsoc/first-introduction-to-open-source/This is just a rant on how I got stuck on Open Source community and loving it. 6 month ago, at about October 2016, I just a normal college student who love programming.
