bobek··on Flip Fluid on Flip Dots
I have recently resurrected one from an old bus — https://www.bobek.cz/buse/
bobek··on Everything I own, owned
TBH this is one of a few things that feels exciting about LLMs. I've recently revived a flip-dot panel from an old bus by reverse engineering and replacing its firmware -- https://www.bobek.cz/buse/
bobek··on Unlocking a locked/deactivated e-waste Cricut Maker
It it less crazy that it sounds. I have recently replaced firmware on an obscure MCU to revive a flip-dot display.

This resonates. I have just got back to hacking an old flip-dot display after sitting on the shelf for years.

Git back hacking an old flip-dot display. It was sitting on the shelf for years.

bobek··on A New Typst Template for Pandoc (2025)
This template is a great starting point. I have tweaked [0] it for A4 and two-column output, if anybody is interested.

bobek··on I spent 50 hours drawing a line graph
Graph paper FWT :)
bobek··on Is Bitwarden Getting Enshitified?
Bitwarden scrubs ‘Always free’ and ‘Inclusion’ values from its website as longtime execs step down
bobek··on Self-updating screenshots
Plus we had a visual diff on the top of that as a part of the CI pipeline. It prevented a bunch of mishaps ;)
bobek··on I turned my Kindle into my own personal newspaper
I went the complete opposite and print one A4 every morning [0], so I don't have to touch any device.

bobek··on Building a Procedural Hex Map with Wave Function Collapse
Made me smile. Thank you!
bobek··on Decision trees – the unreasonable power of nested decision rules
And you are absolutely correct. I've seen the DT page thanks to the linked HN submission (actually comment [1]. And incorrectly associated the DT article incorrectly today. Thank you.

bobek··on Decision trees – the unreasonable power of nested decision rules
Wow. This page is actually a product of LLM [0]. So they can produce useful stuff after all :)

bobek··on TikTok's 'addictive design' found to be illegal in Europe
It is not only recommender though. These guys [1] seem to be able to react pretty quickly and not to create addicts on the way ;(

bobek··on 2026 will be my year of the Linux desktop
Welcome ;) Linux is my desktop last 20+ years.
bobek··on The best things and stuff of 2025
Interesting, my favorite one on Android - HiPER Calc - does it correctly and returns 1.
bobek··on Feedback doesn't scale
The biggest (engineering) team I've built and led was 150 people, so I cannot speak for 200. I don't feel that the solution of keeping the understanding of what is happening was about a formal structure like an "employee steering committee".

Rather than trusting the same principles used for scaling the doing side of the business. Things like empowering people to make decisions [1] or being clear about what/how/why you make certain types of decisions [2]. Working on staying aligned with your closest team, which then spent energy on staying aligned with their teams, etc. Sample randomly from the whole org, but mostly at your pace.

The biggest mistake I've made was that I've pulled myself (for legitimate reasons, it seemed) from having a true conversation with every single hire before they've gotten an offer, when we were around 70. 30 minutes is typically enough, but I feel you need a singular person as a gatekeeper for the final values-fit check. Partially thinking that 70 is already good enough, but later I've come across people talking about, like, 500 people before pulling out [3] :)

bobek··on Attention is a luxury good
Adam Grant had recently Daniel Immerwahr on attention span and how it really has not shortened despite popular beliefs.

In the age of social media and short-form content, many people insist that our attention spans are getting shorter. But historian Daniel Immerwahr reminds us that people have cried wolf for centuries about technology hijacking our attention. In this episode, Adam and Daniel dive into evidence that what’s changing is not our attention spans, but the objects of our focus. They also discuss moral panics of the past, compare the cognitive benefits of video games and the opera, and debate whether or not Marvel movies are a waste of time.

bobek··on If you're remote, ramble
Mildly related are written standups [1] when treated as journal/logbook.

bobek··on Rotring 600 Ballpoint Pen
Love Pentel Graphear 1000, have multiple distributed throughout the house/workshop and backpacks :)

The other I really like is UNI Kuru Toga, the plastic one (shrug). The twist mechanism actually works; it is slightly wider thus more comfortable (for me) for longer writing sessions.

bobek··on Jeff Bezos doesn't believe in PowerPoint, and his employees agree
The site appears to be down. HM hug of death, maybe?

Writing isn't just communication—it's a thinking tool that forces clarity and precision. Yet I still get pushback when advocating for written narratives over slide decks in technical decision-making. Writing is frequently considered "extra work" :(

I was even so frustrated that I've put together https://www.bobek.cz/written-narratives/

bobek··on Make Your Own Backup System – Part 1: Strategy Before Scripts
It is not particularly hard either. Checkout restic server.

bobek··on Show HN: I made an online Unicode Cuneiform digital clock
I always liked the esthetics of Wharton studio clocks. There is an OSS implementation at https://github.com/bobek/sdg_wharton_miniclock
bobek··on Meta found 'covertly tracking' Android users through Instagram and Facebook
Well, it is the same as all those examples of people "just doing their jobs" in concentration camps. Being compliant, focused on execution of their ~orders~ process. Interestingly, many people are being pre-emptively harsher, than required/requested. Checkout "Those Who Said No" (DOI 10.2307/1429971).
bobek··on Merlin Bird ID
Go for it. Running it for quite some time at home. Very easy to deploy, regular updates.
bobek··on Bank transactions cleared by FTP-ing files
Once, I got pulled into a fintech company who done synchronization of remote psql databases by dump to csv -> send over ftp or email -> verify in Excel -> import back to centralized psql. No wonders, they have been missing some transactions...
bobek··on When a team is too big
I would recommend a slightly different approach to written/async standup. Issue I have with stand-ups is the ad hoc nature of proving a report, instead of making it a collaboration space

bobek··on Search could be so much better. And I don't mean chatbots with web access
Maybe try Kagi. I am pretty happy with the results.
bobek··on AI will change the world but not in the way you think
It is like https://marketoonist.com/2023/03/ai-written-ai-read.html being written down at length.

I do agree with the fact, that this is an annoying phenomenon. It took me a while to understand that there are people who are not just using LLM to write these style of emails, but those people are the source of the training data for LLMs.

The solution is "simple", to move aways from such people and stick to genuine communicators.
