Re:Pi Is the Last Harness on Monday November 02, 2026 @05:53AM (#50335241)
Completely. You just use their api and you pay for it. The harness needs to speak the anthropic messages protocol or you use a proxy that does the translation for you.
I turn mine to dumb again as the smart functions are not smart enough and I spend more money than a basic calendar.

The procedure is simple. 2 fix periods : one in the morning one in the evening and in between if somebody comes home he/she turns the heat manually.

I didn’t see any advantage more inconvenient: * saw people at home that were not * started to heat the whole house while I just work in my office.

I have not yet found a practical case except that I can turn it off remotely when I’m on vacation if i forget.

Are any people here getting any advantages?

Re:Why harnesses matter for energy (and token) efficiency on Saturday October 17, 2026 @12:01PM (#50132252)
So difficult to read.

In my opinion, Harness has nothing to do with energy (ie cost). They all use the same conversational requests so the efficiency is mostly in the prompt (instruction and data) as well as the chosen model.

Choose wisely.

For efficiency, providers should cache the initial prefix (ie system prompt and tools) of harnesses, not sure if they do all that.

tell me is there some society you know that doesn't run on greed?

Re:Cheap self-hosted Kubernetes on Hetzner cloud (2025) on Tuesday August 04, 2026 @12:33PM (#49171239)
You need to see Kubernetes as a wrapper of the init thread (systemd).

If you fought with cgroup to tame resource (memory, cpu) consumption you know.

You get also controlled rollout for free.

Likewise, it’s also a platform so you get installation receipts of third party software’s for free.

You install the Prometheus operator and, bam, you get declarative monitoring as code for free.

The ticket entry is not free but once you got it, it’s repeatable and durable.

I use most of this chart:

There is more but it asks a real blog.

Re:Launching My Side Project as a Solo Dev: The Walkthrough on Friday February 06, 2026 @04:33AM (#46910807)
Marketing is an art.

I found the real value of this deck only at the end of the kickstarter page and I went through because I read the blog first.

Every sales needs a story (Rory, alchemy). It would have been awesome to also have a bit of Japanese story on each card or to embed a game in it.

All the best in your endeavours. It’s not easy for sure.

Real Test data génération as saas was not a viable business for us.

Developers use their tool or develop a script (with ai or not)

We made it free, the value comes when you can use it in your development process.

The cost of calling a service is also not free.

In all case, all the best in your endeavour.

Re:GitLab discovers widespread NPM supply chain attack on Friday November 28, 2025 @07:41AM (#46078137)
You can even go further and delete all your secrets from your env by creating wrapper scripts

It’s not completely full proof but at least gpg asks my passphrase only when I run the script

Re:CLI tool to check the Git status of multiple projects on Thursday November 20, 2025 @07:15AM (#45991818)
Nice.

I made a git exec command for that. It executes a command on multiple repos.

So to see the status of your local repositories cloned in the code directory of your home directory

´´´bash

export GIT_X_REPOS_FILE=~/code

git exec status

´´´

Code: https://github.com/gerardnico/git-x/blob/main/bin/git-exec

Doc: https://github.com/gerardnico/git-x/blob/main/docs/bin-gener...

You should give a better name in google oauth. I get

Google will allow project-316434798136 to access this info about you

Can’t wait to see if you extract the transcript on TikTok’s ?

A good reminder that building software is hard.

And that you may fail even in your domain of expertise.

All the best to the core dns.io teams.

We all feel the pain.

Re:Show HN: Gradle plugin for faster Java compiles on Wednesday June 04, 2025 @07:28AM (#44179511)
Exactly, gradle is so slow that I ditch it into the ground. Just starting a blank project is so a bad experience. Nothing beat maven and a couple of shell script.
I was looking a documentary in Netflix (night stalker) and men all transitions between scene were Ai generated.

Instead of creating a tag, you could add the time in your commit message as a footer key following the conventional commit spec.

Re:If Not React, Then What? on Saturday November 30, 2024 @03:49AM (#42280434)
A framework is declarative. You declare what you want. Generally in a configuration file and you get an app.

A library does not impose any configuration. I don’t see any required configuration with React. You can use it wherever you want in your code as an addition.

Re:Do not use secrets in environment variables on Monday October 07, 2024 @04:01PM (#41770322)
I made a direnv extension for that purposes.

It loads env files and call hashicorp vault if the value is a secret.

I find it pretty neat to have an env file that describes all environments variables.

https://github.com/gerardnico/direnv-ext

I got involved in the oracle forum in 2005. I was just tired to answer always the same questions. I posted them online and got first for whatever reason on Google Search. That’s how datacadamia has started.

I got my second job because of the forum, my third one because of my website. Not that they contacted me directly but during the technical interview, my interviewer was a reader and pretty excited to get me on the team. With an Ai era, it would have been more difficult I guess. The good side is that writing allows you to make connection in your brain and in the outside world.

All the best

Don’t forget that happy people have a far more chance to get and stay married.

Marriage is not the cause of happiness.

I’m a quite old computer guy in its 50s and I give here and there what you would call a soft skills class.

This kind of class will give you a lot of mentorship, not only from an individual point of view but also from the group point of view. They are also a place to get new safe friendships outside of your company.

If you would like to discuss more, you can contact me at my login alias at gmail.

Will try that. Thanks
Sorry for the late answer but I didn't get any notifications.

The number of visitors is now down to 500 a day but it's going down surely but slowly since a couple of year.

To be honest, I didn't work on my SEO. I used to be first in SERP for a couple of keywords and I can see that this is no more the case.

The domain authority has gone from 55 to 30.

I'm not sure if I need to take this figures seriously as I'm not a SEO specialist.

Here the slope on this year only.

Next to the SEO thing, I'm pretty sure that there is a strong LLM correlation.

Thanks gus.
