iamchp··on Sit.
> immersion effect Totally agree. At the moment, add to home screen creates a shortcut that opens up Safari (along with its other distracting tabs ;) would be great if Sit could be set up as a web app too!
iamchp··on Ask HN: How many of you are open to Piracy again?
I’m seriously considering piracy because streaming services don’t offer subtitles in my mothertoungue. I come from a non-english speaking country and I live in a foreign country. Some movie offerings provide my mother tongue, but others don’t, and this is super annoying :’( I really wish content providers would just add on all subtitle languages :(
iamchp··on SK Hynix Reveals DDR5 MCR DIMM, Up to DDR5-8000 Speeds for HPC
Computer architects use the term 'memory wall' to refer to this latency problem. CPU microarchitectures are constantly improved to improve IPC, Die technology helps increase CPU frequency, but memory access latency is not keeping up with the CPU improvements.

This would benefit sequential access, but it'd either be disabled for random-access or pollute the caches with unused lines.

But in cases where sequential memory bandwidth is required, this is pretty cool! (But I assume Intel only, which would also be a bummer)

iamchp··on Java 20: A Sneak Peek on the Panama FFM API
Thank you for this pointer. I was also wondering what the motivation for FFM was (I'm not a Java person), but reading the JEP answered my question!

The JEP is really elegantly written!

iamchp··on I/O is no longer the bottleneck
Thank you for this (albeit a different project). My immediate question when I read the last part of the page was 'What about PyPy!?' PyPy might be different for the original post's execution, but I still assume some significant speedups?
iamchp··on Improving Firefox stability on Windows by retrying failed memory allocation
Awesome to read about the memory management in Windows. (To me Windows seems to much of a black-box, but this is also because I only develop on Linux)
iamchp··on Seeing through hardware counters: A journey to 3x performance increase
The JDK issue ticket linked towards the bottom of the post has some interesting discussions. Apparently Developers at RedHat ran into a similar problem and decided to build an 'agent' to help developers identify code patterns triggering the issue.

Slightly different approach to the Netflix post, but still an interesting line of effort to find problematic Java code!

For anyone interested: https://bugs.openjdk.org/browse/JDK-8180450?focusedCommentId...

iamchp··on Netflix: Love is sharing a password (2017)
Totally agree. There should be a cheaper option of one-screen 4K and without the games. I don't understand why I need to pay for the games that I don't want to play.
iamchp··on USB Charger (USB Power Delivery)
Reflecting, this is quite off topic, but due to more voltages supported by USB PD, I thought I'd bring this up.

A few years back, I really wished all the AC/DC converters for smaller home appliances would ditch the fragmented round pins, and go for a universal USB-A (at the time) standard. E.g. some fans, routers, my smart desk, my key light, etc. Perhaps we would be able to optimize better unified AC/DC converters.

Perhaps it would be nice to think about something like this. Instead of having bulky AC/DC converters, go for single multi-port USB-C PD converters?
