AlphaWeaver··on Ask HN: How to find a new job when I'm not good at networking?
It's true that networking often plays a significant role in finding a new job. If you find it hard to build new relationships, that's OK, because that skill can be learned.

Most introverts I know don't enjoy being around people all the time, but still build and maintain meaningful relationships with a small number of people close to them.

If you do want to be better at this, but you're finding it difficult, have you considered therapy? A good therapist can help you feel more confident in building relationships, so you don't feel as drained by them, and give you a safe space to learn and practice those skills.

AlphaWeaver··on What happens to our breath when we type, tap, scroll
There are lots of meditation apps out there, but most monetize with a subscription plan before you can access any meaningful amounts of content.

Recently I found an app with a pretty large following called "Insight Timer" that has a spectacular free library. It has single-handedly helped me build a habit after only meditating once or twice in guided settings.

AlphaWeaver··on What I think about Lua after shipping a project with 60k lines of code
> After that, I went back to Dmitry and asked him if my understanding of “everything is a table” was correct and, if so, why Lua was designed this way. Dmitry told me that Lua was created at the Pontifical Catholic University of Rio de Janeiro and that it was acceptable for Pontifical Catholic Universities to design programming languages this way.
AlphaWeaver··on Act on Press
In some safety critical software, it's important to do the opposite, to provide a means for a user to abort partway through the action of clicking (by dragging their mouse off the control with the button still held.)
AlphaWeaver··on Contact of Containership Dali with the Key Bridge and Subsequent Bridge Collapse [pdf]
This is a fantastic example of clear technical writing! The NTSB goes out of their way here to define domain-specific terms (in the footnotes) to ensure this report is digestible by a public audience, which I think is really neat. We need more examples of this type of technical communication from government agencies.

AlphaWeaver··on What's an obelisk, anyway?
No, that's a floppy disk. An obelisk is a mythological snake that will turn you to stone if you look at it.
AlphaWeaver··on Folk Computer
This is so refreshing! As sibling commenter [0] mentions, this is clearly inspired by Dynamicland, and even uses the "Claim/When" syntax that Dynamicland uses to implement their "Realtalk" operating system.

When Omar's post about Dynamicland [1] hit the front page last month, I was frustrated by how little information was available about the project. It seems that the folks behind Dynamicland were very against sharing anything online [2] due to concerns about "including everybody".

On the one hand, I admire their vision. But on the other hand, it doesn't feel obvious to me that holding back something like Dynamicland would help it ultimately become "available everywhere." Even their answer of "come visit us in person" isn't relevant anymore since their physical space is closed.

I'm very excited about this approach - even if it isn't open source, they've shared far more information about the way the system works. I'm sure this will inspire others and ultimately blossom into something much greater.

Edit: actually, it's open source here: https://git.folk.computer/folk

AlphaWeaver··on Building a fully local LLM voice assistant to control my smart home
See Magentic for something similar: https://github.com/jackmpcollins/magentic
AlphaWeaver··on Kagi.com is unstable for all regions
I appreciate that my search redirected directly to the incident report page.
AlphaWeaver··on The Flo Control Project (2000)
This is a fantastic example of simpler image processing techniques... not everything needs a neural net!
AlphaWeaver··on 37Signals Launches Hey Calendar
This looks interesting, and I'd like to play with it for sure. I bought into Hey early to get my email address, but didn't convert, and kept most of my email on Google.

This would be enough to bring me back to Hey I think, but only if they get interoperability right. I've tried calendars other than Google Calendar before, but when I have to interoperate with Google users (invites come my way) it's always hell. Me accepting their invite ends up with an email to their address with a .ics file, rather than actually updating a status in Google Calendar.

I think something like Fantastical (which pulls in all my calendars from different places) will probably remain my daily driver until someone does this better. Now I just wish they had an Android app.

AlphaWeaver··on Fewer people are buying electric cars in the US
That's an interesting formula - why is it the 4th power of the axle weight?
AlphaWeaver··on Things are about to get worse for generative AI
No legal precedent has been set as of yet. The "precedent" you describe is the argument AI companies have been using (that training their models on information available on the Internet should be considered "fair use") but whether AI training actually satisfies the four-factor test for fair use remains to be seen.
AlphaWeaver··on Show HN: Heynote – A dedicated scratchpad for developers
The calculations alongside the notes remind me of the "dynamic annotations" in Ink and Switch's "Potluck" [0] demo. I wish there were more examples of this in note taking applications - this sort of progressive enhancement from unstructured notes to structured data is useful.

AlphaWeaver··on Flatpack field hospitals that can be airdropped to disaster zones
> A tablet computer included in the cube pack is programmed to minimise assembly errors, and an alarm sounds if the wrong equipment is put in any given cube.

This is incredibly smart! Guessing Ultra Wideband beacons in some of the equipment, so you know what cube it's in!

AlphaWeaver··on You are never taught how to build quality software
In my university, (US, state school,) we had a software engineering course exactly like this. It was great in theory, but in practice, the experience was rushed, the codebase was poor quality, (layers upon layers of nothing features with varying code quality,) and the background knowledge was completely ignored. The application we had to work on was a Tomcat Java Web application with an Angular frontend, when neither of those technologies were taught in any other classes (including electives.)

This approach to education can work, but I think simulating/mocking portions of this would have been more helpful (it could've been a teacher/TA managed codebase we started with rather than the monstrosity passed between generations of students who were inexperienced.)

AlphaWeaver··on The valve at the end of the world
> What a stranger can offer a person in a moment of crisis is solicitude unalloyed by the past or the future of the relationship, unconditional in the true sense of the word.

This is such an interesting idea.

Yes! It's a great film!
AlphaWeaver··on Histotripsy – a technique that harnesses soundwaves to attack cancer
Could this work against any/most cancers?
AlphaWeaver··on Email and Git = <3
In theory modern Gerrit supports this, by storing review metadata in Git notes attached to the repository. Most of the time though, people still use the Web UI.
AlphaWeaver··on We built the fastest CI and it failed
We spent some time evaluating this on my team, and we're still experimenting with it.

I like it a lot, but the project appears to be mostly unmaintained since mid-2021, when the creator left it to work on a lispy CI/CD tool [0] that feels very complicated... not sure what's going on there.

AlphaWeaver··on Show HN: Open-source obsidian.md sync server
What I've long been looking for is a sync service that handles syncing these directories of markdown, but then provides value added HTTP APIs on top of them.

I can sync my markdown files from place to place with ease, but what I really want is the ability to POST myserver.com/newpage and have it artificially inject a new Markdown file at the path I request.

This could be system agnostic, Obsidian, Logseq, and tons of other local markdown knowledge bases could benefit from this.

AlphaWeaver··on My thoughts on the 2023 FTC robotics season
If you've never had the chance to visit an FIRST competition, I strongly suggest you visit an FRC competition (FTC's bigger brother) this spring in March/April.

The field is as large as a basketball court, and the gameplay is energetic and exciting! I was a student on an FRC team in high school, but the program itself was interesting enough on its own to keep me involved post-graduation. I'm now approaching 9 years of volunteering, with no signs of slowing down. It's a fantastic experience.

AlphaWeaver··on My thoughts on the 2023 FTC robotics season
Volunteering with FIRST (I volunteer with FRC) can be a surprisingly fulfilling experience on its own! You still get the excitement of watching the competition, while getting the chance to mentor and support the brilliant young students making their way thru the program.

Many regions also have lots of regular returning volunteers, making the volunteer camaraderie even better than what I experienced while on a team.

AlphaWeaver··on LED lights will change the world as incandescent bulbs phase out
> LEDs are inherently dimmable.

What? This isn't true. LEDs function using DC current, and are either on or off. "Dimmable" LEDs have chips in the bulbs that use pulse-width modulation (PWM) to turn the diodes on/off at a different rate to create the dimming effect.

All incandescent bulbs are dimmable (on AC power) with no additional hardware other than the dimmer, which adjusts the input voltage to the bulb. Try to do this with a non-dimmable LED and you'll damage the bulb.

AlphaWeaver··on Using Retrieval Augmented Generation (RAG) to clear our GitHub backlog
These are great, thanks!
AlphaWeaver··on Using Retrieval Augmented Generation (RAG) to clear our GitHub backlog
This is a great overview of a RAG workflow, and also composing a complex task down into simple tasks that fit within the context window!

I'm really interested if there is any software or open source projects that make this type of thing easier- specifically the idea of creating multiple "phases" or "tasks" that each has their own LLM prompt and validation rules (like each node in the flowchart.) I think something like that could be very helpful!
