choilive··on How to Figure Out What You're Not Good At
What if you don't have any talents. (Or at least havn't discovered it yet) I seem to be quite mediocre at everything.
choilive··on Instant Checkout and the Agentic Commerce Protocol
I knew this day would come.. but not this soon.
choilive··on EA Announces Agreement to be Acquired by PIF, Silver Lake, and Affinity Partners
Dell did pretty well after going private
choilive··on Intel Is Seeking an Investment from Apple as Part of Its Comeback Bid
Most likely for the foundry business
choilive··on New bacteria, and two potential antibiotics, discovered in soil
There are millions on the lower bound of bacteria species we havn't identified, trillions on the upper bound. Unknown bacteria are literally everywhere, but the simple act of finding and sequencing them is nothing to be afraid of.
choilive··on Ruby Central's Attack on RubyGems [pdf]
Sounds like Shopify has some leverage then to open a line of comms with Ruby Central. "Explain yourselves or we will pull funding"
choilive··on Bringing fully autonomous rides to Nashville, in partnership with Lyft
The USA has proven to be... incapable of completing any public transport infrastructure anywhere near on budget or on time. This is a deeply rooted problem. Until this gets solved autonomous electric vehicles could theoretically just leapfrog the problem altogether. Point to point transportation also mostly solves the last mile problem.
choilive··on Show HN: Omarchy on CachyOS
Omarchy auto installs the nvidia drivers and fixes if it detects an nvidia card. https://github.com/basecamp/omarchy/pull/13
choilive··on Immunotherapy drug clinical trial results: half of tumors shrink or disappear
While promising, be VERY skeptical about efficacy claims of these early stage research drugs.

Tons of drugs in the pipeline that goes after these promising receptor targets. PD-1/PD-L1, CD47, CD40 (as mentioned in the article) etc. Keytruda (PD-1) is an incredible success both clinically and commercially, but there are many many other drugs buried in the clinical trial cemetery that initially showed promising results.

Medicine is really hard.

choilive··on Apple barely talked about AI at its big iPhone 17 event
Semantically, AI has always been a superset of ML. So it's always been correct to call machine learning AI.

All machine learning is AI, not all AI is machine learning.

choilive··on iPhone Air
iPhone hasnt been a status symbol in many years. Its as mainstream as a Toyota Corolla.
choilive··on AMD claims Arm ISA doesn't offer efficiency advantage over x86
In most cases, efficiency and performance are pretty synonymous for CPUs. The faster you can get work done (and turn off the silicon, which is admittedly a higher design priority for mobile CPUs) the more efficient you are.

The level of talent Apple has cannot be understated, they have some true CPU design wizards. This level of efficiency cannot be achieved without making every aspect of the CPU as fast as possible; their implementation of the ARM ISA is incredible. Lots of companies make ARM chips, but none of them are Apple level performance.

As a gross simplification, where the energy/performance tradeoff actually happens is after the design is basically baked. You crank up the voltage and clock speed to get more perf at the cost of efficiency.

choilive··on I should have loved electrical engineering
Fixing consoles is also treating circuits like black boxes :) . just gotta know what the black boxes are
choilive··on I should have loved electrical engineering
Control theory was also one of my favorite classes that a low of software people should learn (at least the very basics). So many hand rolled heuristically driven if/else type systems that can simply be replaced more reliably with a PID.
choilive··on ReMarkable Paper Pro Move
Hilarious. Especially compared to the USB-C connector on an iPhone, which is secured by 6 (!!!) screws to the frame.
choilive··on ReMarkable Paper Pro Move
I believe most of those are 4:3, but point taken.
choilive··on ReMarkable Paper Pro Move
I have a friend that went through 3 remarkables due to failures, I didnt dig into the root cause but I suspect you might be right on the USB-C port since they all "stopped charging".
choilive··on ReMarkable Paper Pro Move
Its unfortunate that the supply chain for eink/epaper displays all seem to be centering on typical mobile device aspect ratios (like 16:9 for this device) particularly because remarkables are marketed as productivity oriented replacements for notebooks.

I would much rather have a A6 or A5 sized display or any other standard size for paper notebooks.

choilive··on Evidence that AI is destroying jobs for young people
I had the same thoughts, there are clearly indicators that the weakness in the labor market started happening before LLMs and AI took over popular discourse.

All the more reason to believe that while correlated, LLMs are certainly not the largest contributor, or even the cause of the job market weakness for young people. The more likely and simple explanation is that there are cracks forming in the economy not just in the US but globally; youth employment is struggling virtually everywhere. Can only speculate on the reasons, but delayed effects from questionable monetary and fiscal policy choices, increasing wealth gaps, tariffs, geopolitics, etc. have certainly not helped.

choilive··on Let's get real about the one-person billion dollar company
Do athletes count?
choilive··on Qodo CLI agent scores 71.2% on SWE-bench Verified
Wrappers are a bit pejorative and reductive - everything is a wrapper around something else.
choilive··on kurzgesagt: South Korea's demographic issue is killing their country [video]
Also unfortunate that SK seems to have gone overnight from a generational family unit to the western style nuclear family. All of those elderly living in poverty despite modern SK built on their backs.. I am sure they would love to contribute to raising the next generation of children.

There are so many cultural factors in SK that might take generations to reverse without being "forced" by the government (which is also wary to enforce). Of course, by then its too late per the video.

choilive··on Ask HN: Any insider takes on Yann LeCun's push against current architectures?
Most brain damage would not be considered in the realm of what most people would consider "recoverable".
choilive··on Show HN: We built a Plug-in Home Battery for the 99.7% of us without Powerwalls
This doesn't put power back through the home. It acts more like a UPS. You plug in the stuff you need up during an outage to the back of it like a power strip.
choilive··on Launch HN: Cenote (YC W25) – Back Office Automation for Medical Clinics
The insurance companies have already enshittified the medical back office to levels beyond comprehension.
choilive··on Launch HN: Cenote (YC W25) – Back Office Automation for Medical Clinics
Is a world where nobody needs to work a utopia or dystopia?
choilive··on Apple M3 Ultra
For inference the bandwidth is generally not parallelized because the weights need to go through the model layer by layer. The most common model splitting method is done by assigning each GPU a subset of the LLM layers and it doesn't take much bandwidth to send model weights via PCIE to the next GPU.
choilive··on Apple M3 Ultra
never understood the hate on the trash can. Isn't the mac studio basically the same idea as the trash can but even less upgradeable?
choilive··on Apple M3 Ultra
What company was specc'ing out a 6 figure machine just to put in a consumer class SSD?
choilive··on Apple M3 Ultra
Also should note that 800/819GB/s of memory bandwidth is actually VERY usable for LLMs. Consider that a 4090 is just a hair above 1000GB/s
