New comment by duman in "Sun Clock"

That’s actually pretty close to what I ended up building.

For the first one, I skipped the map and went with search + saved cities instead. All your saved places sit on the same 24-hour dial, so you can see the difference from your local time at a glance without doing the timezone math. The upside is that it works completely offline and fits nicely on Apple Watch too.

Your second suggestion is the part I only got halfway right. You can move the dial in 15-minute increments and the daylight/twilight colouring changes with it. There’s also a calendar where you can jump to any date and time and see what the solar state is in every saved city, but right now that’s shown in rows rather than by recolouring the clock itself.

I like your version better though, hovering/scrubbing a time and having the whole clock recolour for that moment would make a lot more sense. I’m going to add that to the list.

I’m the developer, btw: https://apps.apple.com/app/id6797192832

Show HN: Glimpse, Markdown reader using Apple's on-device foundation model

duman — Fri, 22 May 2026 14:11:07 +0000

Glimpse is a native macOS markdown viewer. The thing I built it around: the AI features run entirely on-device through Apple's FoundationModels (the same model behind Apple Intelligence). Summaries, key insights, an auto-glossary of jargon in whatever you're reading. Nothing leaves your machine, no API key, no account.

I read long markdown all day, mostly engineering docs and RFCs, and the existing options frustrated me. Electron apps felt slow. The fast native ones had no AI. The ones with AI wanted me to send a private spec to someone's cloud to get a summary. I wanted to open a 40-page doc and ask "what's actually new here" without it leaving my Mac.

Other things it does: double-click any rendered block to edit just that part of the source, file watching that doesn't fight you while you edit, presentation mode, KaTeX and Mermaid offline, and a QuickLook extension so .md files preview the same way in Finder.

Worth being upfront. AI needs macOS 26 because FoundationModels doesn't exist before it. The viewer and editor still work on older macOS, AI is just gated. Mac App Store only right now. 14 day free trial, then monthly or yearly subscription. I went with subscription because I want runway to keep shipping, but I'm honestly not sure it's the right model for a tool like this, so push back if it bugs you.

New comment by duman in "Turkey bans use of cryptocurrencies for payments"

As a Turkish citizen I can say that the real inflation is much higher than 17% but they are trying to make it look lower by changing the formula constantly so they don't have to raise government employee's salaries so much. I would say the real inflation is closer to 50%.

New comment by duman in "Netflix might be overcharging you if you are a frequent traveller"

duman — Fri, 14 Sep 2018 21:25:45 +0000

There is nothing wrong with charging different prices for different countries. The problem is I'm living in Turkey most of the time and my bank is a Turkish bank but I have been charged in Polish Zloty all these time. I don't think they would let me pay less if I created my account in a country 2 years ago where price was 2,5 times cheaper than my original country.

Netflix might be overcharging you if you are a frequent traveller

duman — Fri, 14 Sep 2018 21:12:22 +0000

I thought there might be other people like me on HN who travel a lot for work so I want to share my experience with Netflix's unfair charging policy. I live in Turkey but I travel a lot for business and seems like I've created my Netlix account with Standard plan when I was in Poland 2 years ago. Today I have just noticed that Standard plan is 27.99 Turkish Lira in Turkey but I've been charged 43 Polish Zloty since 2 years and it is equal to 71 Turkish Lira. I wouldn't mind if it was a small amount but since the difference is quite big, I've contacted customer service for a refund but they refused to return the extra money I've been paying and I'm told that there is nothing they can do to compensate this unfair charge which is quite disappointing to me.

So, please check where you created your Netflix account if you don't want to be charged unfairly.

I don't think using "the wrong letters" is illegal in the US. What I've meant was it is as wrong as claiming the usage of "the wrong letters" is illegal in the US.

The letter Q was never illegal in Turkey. It was just not allowed to be used in names of people/companies etc. due to the fact that it is not in Turkish alphabet.

It is like letters ç,ğ,ü being illegal in US.
