New comment by hashhar in "Show HN: Ferrite – Markdown editor in Rust with native Mermaid diagram rendering"

hashhar — Sun, 11 Jan 2026 21:33:52 +0000

The only thing I'll say is that it's great to see the feedback in this thread applied. It became very obvious to me what the tool is for and an abstract idea of what I can do with it.

However as others have said:

- A demo video would do a lot for your product.

- nit: Real-time markdown -> change to something that emphasizes collaboration/collaborative editing. For two reason - it's a much more familiar term in the space you are building and it's easier to understand (I think) for more people.

- A sample workspace (either public or a "starter workspace" that's available by default in a new account) that is non-trivial would be great to showcase your product. Look at obsidian using obsidian itself for it's own documentation site.

- Your about page is very well written - I wonder if you can pull up somethings from there onto the main page. https://hyperclast.com/about/

I didn't sign up yet however so can't provide more feedback.

Doesn't help much because even the standard library bitrots after enough Python releases. I have things I write today but can't run on a NAS that has older Python. No issues like that with Powershell for example.

Which of those are evolving at the rate of frameworks?

BTW I'm of the opinion that frontend tooling developers should actually try to contribute things to HTML and CSS instead of building "component libraries" on top of them.

If the native controls were good and if the browsers allowed using "uniformly styled" versions of them then there would be no good reason for such libraries to exist.

It's both reassuring and frustrating. Reassuring because they decided to secure IPC somehow. Disappointing because this is such an unexpected failure mode.

My scroll direction broke, custom operations that I had apparently "saved" to the mouse also stopped working.

New comment by hashhar in "Opus 4.5 is not the normal AI agent experience that I have had thus far"

Codex for me behaves very junior engineer-ish. Claude is smarter and tries to think long term.

A great example of their behaviours for a problem that isn't 100% specified in detail (because detail would need iterations) is available at https://gist.github.com/hashhar/b1215035c19a31bbe4b58f44dbb4....

I gave both Codex (GPT5-ExHi) and Claude (Opus 4.5 Thinking) the exact same prompts and the end results were very different.

The most interesting bit was asking both of them to try to justify why there were differences and then critiquing each other's code. Claude was so good at this - took the best parts of GPTs code, fixed a bug there and ended up with a pretty nice implementation.

The Claude generated code was much more well-organised too (less script-like, more program like).

Redbook is also the Audio CD standard. Lots of redbooks exist.

New comment by hashhar in "How private equity is changing housing"

hashhar — Tue, 09 Dec 2025 20:01:56 +0000

The area I live in has homes that remain empty because the investor doesn't need the capital nor the space and just holds empty units for multiple years when they eventually sell (for even more than they would have sold in the past).

Housing demand will always be > 0 as long as population is growing and hence there can never be a oversupply.

It's trivial to enumerate all the phone numbers in the world.

New comment by hashhar in "The scientific “unit” we call the decibel"

hashhar — Thu, 22 May 2025 08:50:20 +0000

Going from -50dB to -44dB is a much louder change than going from -6dB to 0dB.

Human hearing is logarithmic. The dB is measuring ratio of sound pressure level and it's accurate that +/-3dB is almost doubling/halving of the SPL.

hashhar — Thu, 22 May 2025 08:45:24 +0000

This is exactly it. The people who get confused by decibels are treating it a unit in it's own right when it's really just a ratio of some unit.

You only really need SSH access on a box to use it as a git remote - no server needed.

I learnt this quite late and was not obvious to me so hope it's helpful for you too.

Not really. Downloads is out of bounds and the root folder is also out of bounds.

WhatsApp media lives in separate folder.

PDFs that I download live in downloads folder (which you can't give access to for some reason anyway).

Music lives elsewhere and so on.

PlexAmp has DJs which allow you to get the song/playlist based radios.

LMS (Logitech now Lyrion) also has something similar in MusicIP (not as good as PlexAmp).

Plexamp can surely do bit-perfect playback, not vanilla Plex though.

New comment by hashhar in "TikTok preparing for U.S. shut-off on Sunday"

hashhar — Thu, 16 Jan 2025 00:48:30 +0000

I'm from India too (but at-least a generation older than this kid) and to clarify:

proposed = asking for a date or if he's too forward / self-centered then asking her to "be my girlfriend"

crush = a girl I like but haven't told that to her or shown it in public

And yes for kids in school it's quite common to initiate conversations through mutual friends because otherwise gossip spreads too quick and can sometimes be damaging (both emotionally and socially).

New comment by hashhar in "IPv6 may already be irrelevant – but so is moving off IPv4"

hashhar — Thu, 24 Oct 2024 20:55:52 +0000

Yes, a lot of ISPs do this even after I try to write to them explaining why it doesn't make sense. My ISP is Airtel in India, they very recently started assigning IPv6 at all but it's a single /64 only.

The other big one I know, Jio (from Reliance) also offers just a single /64.

New comment by hashhar in "Optimizing Postgres table layout for maximum efficiency"

hashhar — Tue, 08 Oct 2024 17:00:10 +0000

I'm not sure, there's also HOT-updates (heap-only tuples). It's an optimization where data in modified in place if none of the modified columns are part of an index and maybe other conditions but I don't remember it all too well.
