Tell HN: The Codex App is replaced by ChatGPT

vintagedave — Mon, 13 Jul 2026 10:12:59 +0000

Hi HN. Today Codex (macOS) prompted to upgrade, and it failed - the app is gone, but was not replaced. The dock icon shows a question mark.

To fix this I tried to download the Codex app from OpenAI. https://developers.openai.com/codex/app redirects to ChatGPT. The Codex page itself (https://openai.com/codex/) talks about 'now in ChatGPT' and prompts to download.

Sure enough, downloading what appears to be Codex downlaods ChatGPT -- and so opening 'Codex' loads all my personal chats, non-work conversations, etc.

I cannot emphasise enough how much this is a disaster. I cannot mix my personal and work use - not least just for keeping them separate (I do not want to see personal chats while working.)

The OpenAI claim seems to be that you can run it in Codex mode? Yet there is zero UI for this. ChatGPT claims it's got the latest installed. Currently my entire Codex workflow is gone.

Some form of Codex is still available via GitHub releases, latest here: https://github.com/openai/codex/releases/tag/rust-v0.144.3 but I cannot find the app itself. There is the CLI, the app server... 163 different downloads, but no macOS Codex app.

Do you write with AI? Do you think people notice?

Gravityloss — Mon, 13 Jul 2026 09:46:50 +0000

I use AI myself so I definitely know how it tends to write. When I encounter that kind of writing somewhere, I initially give it the benefit of the doubt and continue a bit. But when the signs get too obvious, I tend to just stop reading.

It feels like the prompter is trying to trick me. They might for example have some simple agenda but they're trying to dress it up as some objective rational analysis with the help AI.

It would work better if the author told how the content was created, and even shared the prompt.

Ask HN: Which Chinese open source projects are you using?

khurs — Mon, 13 Jul 2026 08:49:58 +0000

Alibaba, Tencent and others are releasing a lot of software via GitHub/Apache/CNCF but I don't see a lot of usage in the west.

Anyone using a Chinese database or other open source products?

Ask HN: What was the initial reaction to search engines?

hopa — Mon, 13 Jul 2026 05:48:41 +0000

My manager the other day mentioned AI reminds him of when search engines like google were first popularized, whereas before you needed a lot of specialized knowledge that was hard to acquire, whereas after knowing obscure details became less important and knowing what to search for became more important. I’m curious for anyone who remembers - what was the reaction / discourse around search engines at the time? Was there a similar reaction to the rise of LLMs?

Run SSH and Claude Code on 3DS

cadl11 — Mon, 13 Jul 2026 03:58:21 +0000

I found an open source homebrew 3DS application that can connect to a remote host via SSH and run Claude Code on it. I tested it on my own 3DS,the experience was great—it even supports voice input.

With the 3DS's dual screens, analog stick, multiple buttons (mapped to Ctrl, Alt, etc.), and voice input, using Claude Code is very smooth. I also ported the Tailscale library to the 3DS and used it in my local build, so I can use my 3DS to control my computer and run Claude Code/Codex anytime I'm in a network environment.

The repository link is: https://github.com/Fishason/DSSH

3DS is so cool.

Ask HN: Add flag for AI-generated articles

levkk — Mon, 13 Jul 2026 01:24:20 +0000

Should HN add the ability to flag articles as AI-generated? This doesn't have to act as a regular flag, i.e., it won't de-rank the article; it could just show up as an indicator, allowing others (like myself) who don't like reading AI-generated text, to skip it.

Open questions:

1. Why is the regular voting system not enough?

2. Should HN change in response to the gen AI era? It has been successful not changing fundamentals.

Ask HN: How do you use LLMs for private discussions?

emerongi — Sun, 12 Jul 2026 22:17:12 +0000

I sometimes have things to discuss with LLMs, which are more private than usual. I was thinking how to do it in a way that doesn't reveal my identity.

  1. Use Tor to access the provider?
  2. Create a random account?
  3. Use some form of untraceable payment (which one?)
  4. Scrub all information provided to the LLM from personally identifiable information?

It seems like a lot of effort. So is running a local LLM, for which I don't even have the hardware. How do you do it?

Anthropic extends Fable 5 access through July 19

dboreham — Sun, 12 Jul 2026 21:27:24 +0000

As predicted here (not by me), Anthropic extended the Fable pumpkin date again, to July 19. I don't think there's a web page with this yet but they sent an email today that says:

"We’re extending Claude Fable 5 access on all paid plans, as well as our increased Claude Code rate limits, through July 19."

Ask HN: List of functional institutions fighting towards a free internet

Title, mostly.

Less in the Effective Altruism sense and more in the "private enterprises building technology to uphold freedom and limitless education for the young" sense. [IIRC Founders Fund et al have invested in a couple of companies in those area..]

Ask HN: Would filesystem bookmarks be useful in your shell workflow?

manux81 — Sun, 12 Jul 2026 20:13:17 +0000

I’m experimenting with a small shell utility for filesystem bookmarks, and I’d like to understand whether this is a problem other people have.

The idea is to define persistent or temporary bookmarks for directories:

``` bm add work ~/Work bm temp build /tmp/build ```

and then use them directly in paths:

``` cd @work ls @work/project ```

The utility would also support renaming bookmarks, promoting temporary bookmarks to persistent ones, demoting them, and clearing temporary bookmarks.

I’m not sharing the implementation yet. At this stage, I’m mainly interested in how other people handle this today:

* Do you use aliases, environment variables, shell functions, z, autojump, or something else? * Would explicit names such as @work be useful, or would they feel redundant? * Would temporary bookmarks be useful in real workflows? * What would this need to offer to be worth using instead of existing directory-jumping tools?

Let's talk about: LinkedIn ghost jobs

xvxvx — Sun, 12 Jul 2026 20:04:52 +0000

LinkedIn has an obvious problem with ghost job postings.

A good example: received an email of matched jobs. Opened it and followed one specific link only to see they were no longer accepting applications:

https://www.linkedin.com/jobs/view/4439726696/

The job was reposted 7 hours prior and only received 36 applications total.

I always assumed that ‘not accepting more applications’ meant a specific threshold was met. But 36 apps in 7 hours? No.

Thoughts on what’s going on here?

I thought AI-generated content would making online discussion worse (which it definitely does on some platforms), but I haven’t noticed a meaningful drop in the quality of Hacker News posts or comments. Have you?
