tjkrusinski··on Muse Spark: Scaling towards personal superintelligence
The article is published primarily to signal to the market that Meta is serious in its efforts to compete in building frontier ai models.

They want to 1) attract talent, 2) tell wall street they can play in this space as well, 3) help employees feel the company is moving in the right direction.

A frontier LLM doesn't apply to their core consumer products.

tjkrusinski··on Chunking for Code Search using Chroma and Tree-sitter [video]
Video goes over how to chunk code using tree-sitter and loading those chunks into Chroma for search and retrieval.
tjkrusinski··on Electric cars produce less brake dust pollution than combustion-engine cars
Are you constantly accelerating quickly? Haven't had this experience.
tjkrusinski··on Context Rot: How increasing input tokens impacts LLM performance
Interesting report. Are there recommended sizes for different models? How do I know what works or doesn't for my use case?
tjkrusinski··on Semantic Similarity on Structured Data – [video]
Chroma recently added ID filtering at query time, unlocking the ability to rank structured data by semantic similarity. Available now in Chroma v1.0.8

See the full example in this notebook: https://github.com/chroma-core/chroma/blob/e5da83c82450cf15b...

tjkrusinski··on Zig Guide
Zig is great, played with it a bit to compile to WASM and found it to be pretty easy to work with.

That said, they're not winning on the docs, community and marketing front vs Rust. It's not really apples to apples, but it's a comparison people naturally draw.

tjkrusinski··on Show HN: AI text editor with suggested edits in diff view
Looking back, the plan box does show that it is a free trial, but it's not clear at first as my eyes skipped the text that was in the parenthesis.
tjkrusinski··on Show HN: AI text editor with suggested edits in diff view
Love the idea. Since this is a consumer product, making it clear you can try the product before buying is critical. I clicked on the paid plan option, created an account but then was surprised to see that I ended up in the product.

I'd consider a react framework for the UI, shadcn or similar. The overall vibe of the UI doesn't present as cutting edge or on par with other AI based products out there.

In the product, I'd bring the recommended prompts to the surface the user enters the AI prompting mode, rather than hiding them behind the "show prompt tips" button.

The line height on the diff view is a little short, the text is crowded.

Tooltips on the toolbar buttons would be very helpful. Also, creating some hierarchy in the toolbar by dividing into logical sections grouped by tool type would help. Font foratting, node types, etc.

Overall, great job, product itself works really well.

tjkrusinski··on Ask HN: Tips for Interview Preparations with ADHD?
(I have ADHD). First, exercise and diet are critically important, it's the foundation for the rest of your wellbeing.

A big thing for me is preparing my space to be able to get into hyper-focus mode. Do the dishes, clean the house, have everything else that can rob you of your focus out of the way.

You can take this same approach leading up to an interview. An hour or so beforehand, how can you get the flywheel moving to be in "productive" mode by the time the interview starts? Think about a few options here.

Action yields action, so getting the momentum going and keeping it moving helps you feel accomplished. When you feel accomplished, you feel better about yourself and you introduce a positive feedback loop.

You got this.

tjkrusinski··on Show HN: I built a convenient way to get the most out of the Bible
Looks good, neat idea.

Few things:

- Highlighting to then prompt makes sense, but I want to just click on the verse number to have it highlight to then summarize or get commentary on - The text to speech is useless, the system voice on chrome on macos is unlistenable compared to other modern speech synthesis models - The text formatting is strange, I'm used to bible.com or etc where formatting is preserved, not 'one line per verse' as you have it.

tjkrusinski··on Show HN: I'm Building an Alternative to Figma
The .coffee domain is strange. Product looks good overall. I'm not sure why I'd want this over figma though. What's the difference? It wasn't clear reading the home page.
tjkrusinski··on Airfoil
It's amazing how the article did such an incredible job building a deep understanding of how the airfoil works, yet you managed to completely miss that and find something to so small to critique.
tjkrusinski··on So what if Google sends me targeted ads?
This rhetoric is extreme. Do you feel the same?
tjkrusinski··on So what if Google sends me targeted ads?
You are not alone.
tjkrusinski··on The Camera-Shy Hoodie
No, older smart phone cameras lacked IR filters because the IR filter didn't only block IR light, but also a distribution of wavelengths around IR. Filtering out IR means many of the visible light wavelengths are attenuated as well, decreasing the amount of light arriving at the sensor.

With better noise reduction algorithms, more sensitive sensors and lower noise sensors, IR filters are now almost always used in smart phone cameras.

tjkrusinski··on Going full time on my SaaS after 13 years
You love to see it. Matt is a great example of someone who has bootstrapped and built a strong business while mitigating risk for his personal life. Much of the start up dogma tells you this isn't possible, but it is.
tjkrusinski··on Why 536 was 'the worst year to be alive' (2018)
Yes, but our economy is flexible, demand for commodities will fluctuate widely shortly after any catastrophic event, having a likely negative cascading effect on the rest of the economy.
tjkrusinski··on Why 536 was 'the worst year to be alive' (2018)
Coordination of governing bodies at the regional level is really bad in the US. A different agency manages the highways than the roadways than the waterways, each having their own incentives and budgets.
tjkrusinski··on The silent struggles of workers with ADHD
Glad to see this article focus on more than distractibility. In my mid twenties I struggled with managing impulsive behavior. I would regularly say inappropriate things in meetings, unable to understand why I said what I said.

After a lot of work in therapy and many different types and dosages of medications, I'm in a better spot. I've turned what was a problem into something I'm proud of.

Through putting my foot in my mouth so many times, I've grown an ability to say the hard, uncomfortable things. Building a lot of empathy and mental processes has helped me be able to approach conversations and situations head on with (some amount of) grace. I'm a better manager because of it.

However, humor is a requirement for working with me, it's a way I've diverted the impulsive thoughts into something less abrasive. I often wish I didn't make so many remarks or jokes but on balance it's not too bad.

tjkrusinski··on Fuel out of thin air: CO2 capture from air and conversion to methanol (2020)
The former. They're working to eliminate the need for an energy intensive distillation process and they haven't been able to get it to do what they've promised. They say they have a carbon nano-tube filter that can separate water and ethanol but no one's seen it work at high efficiency.

tjkrusinski··on Fuel out of thin air: CO2 capture from air and conversion to methanol (2020)
It was anecdotal, but I met someone who worked with folks who worked there, there's a lot of smoke and mirrors and they don't really have what they say they have. Unfortunate as it looked really promising.
tjkrusinski··on 98.css – design system for building faithful recreations of Windows 98 UIs
Microsoft did actually make a "dark" XP theme. It was available "officially" available but they didn't really market it and it had limited adoption. I stumbled upon it and thought I was v cool for using it.

tjkrusinski··on DaVinci Resolve for iPad
Digital asset management. Simply: indexing and storing large audio and video files in a durable way.
tjkrusinski··on Deployment and infrastructure for a bootstrapped webapp with 150k monthly visits
Less work. You'd need to have a different context for environment variables that adds another level of complexity. Likewise if you had a dependency that needs updating (SSL, etc), you can do it safely on the idle machine without worrying about production traffic.
tjkrusinski··on A Silly Usecase for WebSockets (strobe warning)
Not me in the console: `setInterval(() => {document.body.click()}, 20)`
tjkrusinski··on Sharing learnings about our image cropping algorithm
People abuse tall aspect ratio images to take up more space in the UI to get more attention on their tweets.
tjkrusinski··on Dolt is Git for Data: a SQL database that you can fork, clone, branch, merge
Any info on how this differs from Dat?
tjkrusinski··on Ask HN: What are you working on?
A file receiving service. I edit videos and more often than not, people don't have space in their dropbox or google drive to send me large files.

Madry let's me send people a web page that they can upload files to. I pay for the storage, they don't need an account.

tjkrusinski··on Ask HN: What are you working on?
Are you using the ffmpeg wasm thingy?
tjkrusinski··on ØMQ – The Guide (2011)
Love zeromq. Used it in production for years and it never posed any issues. Well documented, reliable and has a clear purpose. V good.
