conradev··on Engineers will do anything to avoid learning from history
In the few instances that I’ve been able to see a total stranger prompt a model, I learn a lot about them.

The model output is fairly uniform because the models are fairly uniform, but the input is how I understand the prompter’s theory of mind for the LLM.

The higher fidelity the theory of mind, the more productive the resulting conversation is. Basic things, like knowing what the model is even aware of.

It’s okay at subjective product judgements with limited context, and so the best engineers make the most important decisions themselves, constraining the model’s solution space to something looking like success.

Maintaining consistent progress towards a common goal with a bunch of different perspectives is the job.

conradev··on Working with AI Feels More Like Leadership Than Coding
I’ve seen plenty of humans manage other humans in this low effort way. It’s a bell curve, after all!

If a model does something wrong, I don't delete it and rephrase. I explain where it went wrong. I get better results this way!

conradev··on Os8088: A powerful Mac-like OS for the IBM XT, 286, 386
I went to Amazon the other day and ordered a fully custom piece of software. I chatted with the seller about exactly what I wanted, what areas to focus on, and they ended up teaching me a thing or two about the domain. Very similar emotional experience to using a language model, which I’ve totally done before.

It is encrypted ciphertext rotated every 10m in lockstep with your Bluetooth identifier.

You will need to turn off your Bluetooth if you want to stop advertising a rotating random number.

The only difference with the contact tracing is that a key, on the device, can correlate the ciphertext. I have it off because the utility was never demonstrated.

conradev··on Geekbench 7
Borderline useless? Is it just that the numbers are unit-less?

You can extract meaning from them! Find your current computer, find the target computer, calculate the percentage difference. 1000 is 1% better than 990, so it indeed doesn't mean anything at all.

  On social media in China there is an oft-repeated joke that goes something like this: In other countries, governments intervene to prevent anti-competitive behaviour; here (in China), they intervene to curb competition.

conradev··on How to Build a Minimal ZFS NAS Without Synology, QNAP, TrueNAS (2024)
https://diskprices.com/ is great for this

You have SATA or SAS to pick from. The CPU requirements for a storage server are not high. On a typical ATX board you have motherboard SATA and can put SAS controllers in the spare PCIe slots.

My first "NAS" was two 22TB hard drives in a ZFS pool on my motherboard SATA

conradev··on The newest Instagram “exploit” is the goofiest I've seen
My girlfriend's Facebook got stolen via a novel technique a few years ago: https://www.reddit.com/r/facebook/comments/14nbp1a/major_fac...

Once the hacker got in, they enabled PGP with a random key to prevent the account recovery process from working. It took many, many months to get the account back after the attacker used the account to max out advertising spend. Meta did and does not care.

I realize now: why would they change anything? They made money off of the interaction

conradev··on OpenAI and Government of Malta partner to roll out ChatGPT Plus to all citizens
The government does subsidize basic banking, though?
conradev··on eBay Rejects GameStop's $56B Takeover as Not Credible
This is a good joke because they spent $2.4B on marketing in FY25
conradev··on California leaders report four to six weeks worth of gasoline and diesel supply
There’s this crazy thing that happens where you need to use carbon to decarbonize.

Solar panels are made in factories where energy and inputs are cheaper and then shipped on diesel cargo ships to the rest of the world.

Our cars run on gas, so we need new electric ones, but the ships and car carriers are themselves… not electric yet.

Because energy is more expensive, everything is more expensive, including electrification.

conradev··on MPEG-2 Transport Stream Packaging for Media over QUIC Transport
MPEG-TS is used to contain h264 chunks for HLS. MPEG-DASH and the new CMAF standard use fMP4 containers instead. My personal take is that Media over QUIC (MoQ) should support both.
conradev··on iOS 27 is adding a 'Create a Pass' button to Apple Wallet
The design is skeuomorphic, modeled after a standard bifold wallet which gives your physical cards the same treatment.

My current wallet doesn't give me any affordances: https://grifiti.com/products/grifiti-band-joes-3-25-x-1-25-i...

conradev··on Honker – Durable queues, streams, pub/sub, and cron scheduler in a SQLite file
A prepared `PRAGMA data_version` is likely quite cheap to run because it hits the same page every time…

…but some other push-based IPC mechanism would be a lot more battery friendly

conradev··on Cal.diy: open-source community edition of cal.com
It has been $20k for a while now and I’ve admittedly been looking for excuses to buy it
conradev··on Cal.diy: open-source community edition of cal.com
Tempted to buy cal.zone or cal.sucks just to add the paid features to cal.diy. They even made a list!

  Teams, Organizations, Insights, Workflows, SSO/SAML, and other EE-only features have been removed
cal.ws is $630 on Namecheap... the tokens required to build this are cheaper than the domain.
conradev··on Codex for almost everything
You have to install it to enable it, actually! Computer Use is also confined (read and write!) to apps that you've explicitly allowed.
conradev··on Codex for almost everything
Yes! and if you install Computer Use from the Codex App you can also use it from the Codex CLI
conradev··on Ohio prison inmates 'built computers and hid them in ceiling' (2017)
My initial instinct would be that the higher IQ someone is, the better they are able to do most things including control their impulses.
conradev··on Show HN: Stop paying for Dropbox/Google Drive, use your own S3 bucket instead
I love it! How would you position yourself relative to existing OSS products in the space like Filestash or Seafile? I'm trying to pick a solution at the moment, and the mobile experience matters a lot to me.
conradev··on Moving from GitHub to Codeberg, for lazy people
GitHub is free, but the runners are slow and increasingly unreliable.

I use Namespace (https://namespace.so) and I hook it up both to my personal GitHub as well as my personal Forgejo. I’m in the process of moving from the former to the latter!

conradev··on Why I love NixOS
I would just like to give this a big ol’ +1. I did not like Nix when I started. The ergonomics are hard to get around, but the power is honestly hard to overstate.

Coding agents actually help with a lot of the ergonomic issues. If you have an evaluation issue, it can be annoying to climb into nixpkgs to diagnose it. But codex will do that for you.

I’ve found agenix in particular to be really great addition for agents: secrets you can copy around without risk of accidental disclosure.

In a day I can now deploy Caddy, Authentik, Fleet, Headscale, Stalwart, jmap-webmail, Forgejo, SFTPGo, Immich, Grafana, Jaeger, PostHog, etc. and have them all work together. I can do this on a tiny VPS, and codex can actually estimate and test performance to minimize cost.

The equivalent Kubernetes setup wastes so much on isolation and a scheduler that is overkill for anything small.

conradev··on OpenCode – Open source AI coding agent
Codex is using its app server protocol to build a nice client/server separation that I enjoy on top of the predictable Rust performance.

You can run a codex instance on machine A and connect the TUI to it from machine B. The same open source core and protocol is shared between the Codex app, VS Code and Xcode.

conradev··on Ghostling
I think this has been around for a while:

  $ echo 'test' | xxd -i -n foo
  unsigned char foo[] = {
    0x74, 0x65, 0x73, 0x74, 0x0a
  };
  unsigned int foo_len = 5;

I take this back: UTM has Venus in there with KosmicKrisp – the works, as of January. Long live QEMU.

VMWare Fusion is free, even if it is a pain in the butt to download. It also has GPU paravirtualization for Linux/Windows which is the only reason I use a proprietary VMM on macOS these days.
conradev··on I'm glad the Anthropic fight is happening now
I love that you are allowed to go off about how we are a worse country without fear of jail or shunning or anything like that. You are using your rights properly!
conradev··on NRC issues first commercial reactor construction approval in 10 years [pdf]
In Texas and Massachusetts you can actually pick your power provider while paying the natural monopoly for the wires. In time I hope we all can do this.
