dicroce··on 10-acre underground home and gardens in Fresno (2023) [video]
I lived in Fresno for 15 years. I spent north of $400 bucks a month on AC in the summertime (starts in June and goes till early November). I lived in a new home with modern insulation.

I now live in NY and I have a basement. It's generally about 10 degrees cooler. I would have loved that in Fresno.

dicroce··on Timeliness without datagrams using QUIC
I wonder if this guy thinks video GOPs should all be hundreds of frames long because P frames are so much smaller than I frames and since in his world we NEVER use an unreliable network you might as well.
dicroce··on POV-Ray – The Persistence of Vision Raytracer (2021)
Damn, I remember finding POVray on BBS's in the pre internet days. So cool that they have kept it going all this time.
dicroce··on I am sick of LeetCode-style interviews
It seems to me that while passing a leetcode question shows that you might know a thing or two, not passing one doesn't really show the opposite. You could be the smartest / greatest coder ever and you just got a really unlucky question... Or it could be that you're not great when you are nervous, etc...

Also, a lot of the time it feels like the answer to most leetcode problem is some sort of trick.... and if you think of it you are golden and if you don't it sucks to be you. Most of the time I'm trying to write code that is NOT tricky... So in some ways I think the job itself will train you to seek simple clean solutions as opposed to tricks.

dicroce··on I am sick of LeetCode-style interviews
Yeah, that's much better.
dicroce··on "Certainly, here is a possible introduction for your topic" in scientific paper
It's not even buried in the middle!
dicroce··on Quiet-STaR: Language Models Can Teach Themselves to Think Before Speaking
This is fascinating. I had another experience that I think sheds light on some of this. One day I was in my office and the lights were off. I turned around and looked at the dark shape on top of my coworkers desk. For a few seconds I stared blankly and then suddenly I had a thought: PC, it's his PC. Then I started to think about that period of time just before I realized what I was looking at... The only word I can describe what it felt like is: unconscious. Is it possible that consciousness is just a stream of recognition?
dicroce··on Why does holding a key fob to your head increase its range?
When I was a kid I had a tv where the quality of the picture noticeably improved when you touched the antenna... and I had recently heard that humans were mostly water... So I grabbed a glass of water and set it on top of the tv near the antenna and the picture cleared right up. Unfortunately this event made me the IT support guy for the family from then on...
dicroce··on How does a B-tree make queries fast?
I always think discussions like this should start with the following: A database with no indexes is slow. Finding a particular row will require a linear search. Adding an index on a column means that your optimizing finding rows by the values of that column. Hence, an index is really a mapping of a particular column's value to the position in the db OF that row (very likely an 8 byte sized integer that is the offset into the file of the row in question).

This all means we can implement indexes as b-trees where the keys are the values of a particular column and the value is the file offset of the row with that value. You could envision a simple db format where indexes and the main row file are stored in separate files. In such a database you could drop an index simply by deleting the indexes file (or add one by creating it). The main row file actually has all of the data and so indexes can be recreated if necessary (at expense of course).

dicroce··on Exponentially faster language modelling
I think it's good to be concerned and cautious but I also think you are being a bit extreme here.
dicroce··on Study Finds Hybrid Work Improves Mental Health Compared to Remote or In-Office
For me, hybrid > remote only > onsite.
dicroce··on The brain is not an onion with a tiny reptile inside (2020)
Not that the opinion of some random on the internet means anything, BUT....

I think the neocortex for the most part lets other parts of the brain control themselves... and really only has high level access. I think emotions are one of these lower level semi autonomous subsystems... but so are things like autonomous body control, balance, each of the senses etc, etc... The neocortex is playing the "Human" video game and controlling things from a high level... but cannot directly control every aspect of these subsystems... and honestly, this is how complexity is dealt with (if the neocortex could control it all, the whats the point of the other subsystems)?

dicroce··on Before you try to do something, make sure you can do nothing
When I am starting a new project I have learned to identify the unknowns.

"I don't know how to do X, Y and Z."

Before I begin working on the real solutions for X, Y & Z I start by making a test program that does X. It's ok if it requires a ton of scaffolding, or canned data... the important thing is to do X. Then I do the same for Y & Z.

Now that I understand the problem I do a software design. I do this on paper and I purposely do it super quick and not caring about how neat it is... and I throw away designs rapidly as I iterate and improve. Eventually the paper crumbling slows down and I approach a real design.

This is finally the point that I can write "real" code. The unknowns are gone and all the software design iteration happened on paper.

dicroce··on Ask HN: Which recent research paper blew your mind?
Damn. It's like jpeg for neural networks.
dicroce··on Ask HN: Any hardware startups here?
My wife has Diabetes and recently switched to a CGM. She also saw the insanely inaccurate results.... BUT it improves. After a few hours the numbers get more accurate as it adapts to you. Now she does a thing where she overlaps the old sensor with the new sensor for a couple of hours every couple of weeks. She also still occasionally uses the finger prick method because its results are more indicative of where you are going in the short term.
dicroce··on Demoscene accepted as UNESCO cultural heritage in The Netherlands
Second Reality by Future Crew, Timeless by Tran, so many good ones from this era.
dicroce··on XML is the future
The way that I have avoided burnout for all these years is working on my own projects, and building them exactly the way I want to. This gives me the strength to grind through the shitty work I am paid to do.
dicroce··on XML is the future
Never heard such a good argument for why we should all be replaced by AI.
dicroce··on Two years of teaching high school CS
I have been a paid software engineer for about 30 years. 10 to 15 years in I learned to love computer science, but for the first huge portion of my career what motivated me was making things. Demos, Games, etc... Maybe the key is to start building things immediately? Things the learner is interested in making.
dicroce··on Waymo and Uber partner to bring autonomous driving technology to Uber
I bet Alphabet has calculated that of all of the rides a typical ridesharing service offers only a subset is currently serviceable by autonomous vehicles. A deal (or buying) Uber allows them to offer the service on only the rides they are confident they can fulfill.
dicroce··on De-dollarization is happening at a ‘stunning’ pace
The Yuan becoming the world reserve currency would mean the Yuan had significant value outside of China... which would mean Chinese citizens could leave the country with their wealth, and China doesn't want that. What they want is the hurt the US, so propaganda that scares Americans and even causes financial havoc is valuable.
dicroce··on Dune: Part Two – First Look
You know, it was probably super smart not showing Emperor Shaddam IV in the first film. The audience has enough to learn and see that is mandatory it was probably wise leaving out some things that weren't mandatory for the first film.
dicroce··on Ask HN: Side project of more than $2k monthly revenue? what's your project?
Cool. I made one of these too. Open source though... github.com/dicroce/revere
dicroce··on The simplicity of single-file Golang deployments
A single binary is nice...

Perhaps second place is using the rpath origin linker option to create a relocatable application.

dicroce··on Why Steam Deck Is One of the Most Significant PC Gaming Moments in Years
You have had the exact opposite experience of me. Everything I have wanted to work has worked.
dicroce··on Can the double-slit experiment distinguish between quantum interpretations?
This cartoon misled me until I realized that there is no observation without touching. Even "seeing" a particle implies that you bounced a photon off of it... and since we're talking about observing individual particles it makes sense that bouncing a photon off of it would have an effect on it.
dicroce··on Fusion energy breakthrough by Livermore Lab
One thing to consider: Even if you prefer solar, you still need to initially make those solar panels and that is an energy intensive process.

I think we're still probably 20 years away from commercialization of this, but I still think this is a very big deal.

dicroce··on I liberate the ending to Minecraft from Microsoft and give it to you
I think you're being too hard on him here. It looks to me like both sides fucked up in a number of ways.
dicroce··on Show HN: Port of OpenAI's Whisper model in C/C++
This is crazy valuable. Just the other day I had an idea that needed this!

yeah this didn't seem right to me either
