ksec··on A Printer Printing onto Paper
While this is fascinating, I am sitting here wondering if anything has improved in the Inkjet printer world.

Does it still clog up? There are many be one or two more refillable ink printers but are they good? Has printing quality improved?

Or are they still a bag of hurt we should all just hope for better and cheaper colour laser / LED printer.

ksec··on Just imagining a workout can make you stronger (2016)
Martial Arts have been doing these for centuries if anything it is more like modern science rediscovering it. Although I believe it is much more Neural adaptation that muscles hypertrophy.
ksec··on Just imagining a workout can make you stronger (2016)
In Martial Art there are also these imagery training. I thought this is a pretty well known and well studies field?
ksec··on GPT-6.1 Terra
Thank You for OP asking the question and thank you parents for some insight.

>If you have suggestions on how to name our products better......

Too late for that. I hope you guys can at least stick to these naming scheme for at least another 2-3 years going forward. Not everyone follows AI / LLM intensely, and it seems there is a new naming changes every year or so.

At least conceptually OpenAI's naming is easier to understand than Claude.

It terms of capability, it would be great to make it clear somewhere that this is 6.1 Model "+" technical communication, vision and computer use improvements. So that at least we know what we should try with these new release and choose a better model for certain workload.

Right now, other than pricing, it is confusing as hell. And in hindsight I wonder if there are fatigue in choosing one people just go with Open Model and stick with it if it is good enough.

ksec··on The new iPad mini
They have enough bezel room to make it into 8.7" or even 8.9" version without changing the dimensions of the mini.

I believe this is the lightest iPad at only 255g. I just wonder how much more weight can they shave off.

And if they are going to kill the iPad? The current iPad line up is split into Pro, Air, (iPad) and Mini. Surely the mini could replace the normal iPad?

ksec··on The Curse of Soldered RAM
DRAM problems used to be a common thing, at least AFAIK in the 90s up to early 10s. I wonder if that still the case or is it now a non-issue for the first 5 years of usage. Our Watch, iPad, Phones all have more memory than old computers. Even Apple Watch Ultra now has 4GB of memory which I thought was crazy.

If it is not, how would all these appliance with memory doubt with bad memory?

ksec··on iPhone Duo Teardown
>Nearly 10 years in to foldables, and they still bring so many caveats. They are consistently worse for size,

And that is why Apple is only shipping theirs now, it is getter better and finally have a decent trajectory in the next 3-5 years to overcome most of those issues. I mean you can pretty much look at State of the Art from Chinese Android phones to see where we are heading in terms of hardware. They are now to the point USB-C port is the limit of how thin they could make their phone.

ksec··on The Goose Programming Language
First, Congrats on the release!

Do you know if Goose is the first time something like this has been done?

ksec··on OpenSSL 4.1.0
I wonder what is the current marketshare of Libressl and OpenSSL ?
ksec··on Crystal 1.22
One of the biggest complain about Crystal is its compile time. Unfortunately there isn't an easy fix.
ksec··on No more icons in every menu by default
>This leads to overemphasis on the visual aspect ....

For Apple, and specific to Apple, when they fired Scott Forstall, there is no one to protect the software UI guys. The 2012 reshuffle in the name of "collaboration" by Tim Cook saw Design team taking over everything design, including Software. 2013 saw iOS 7 and then they spend 3 years to walk back a lot of iOS 7 UI changes. In 2016 many of their old UI leads "retired". Having no old guards to defend their turf, giving Alan Dye more rooms for power grab.

Since then, if not earlier, despite the whole UI becoming more android and cluster mess, there have been little to zero major UI changes other than new skin.

And like Apple's software, that is 10 years of resume driven development where they just want to ship features after features.

ksec··on OpenBSD 8.0
Phoronix do test BSDs from time to time. But for different reasons I think OpenBSd missed twice. I hope to see the performance gap being close enough we can stop thinking it is very slow.
ksec··on JDK 28
> see the pace of Java development pick up so much over the past few years.

I don't think that is a fair assessment. Java / JVM has been steadily progressing in the past 10 - 15 years. From languages to different part of JVM. It is only getting the sense development being picked up because HN and other social media are finally getting the clicks and interest again. The pendulum swing back because of all of different reasons.

And in reality a lot of these recent landed improvement were 5 - 10 years in the making.

I still don't like its syntax though. But I am not even sure if it is even an issue in AI driven development era.

ksec··on Apple's new 'Switch to Safari' campaign details why you should ditch Chrome
While all my day to day browsing annoyance were all gone by Safari 18.x, there are still bugs or rendering issues that i had to use Chrome now and then. Safari needs to keep grinding for the next 2-3 years and not cut any resources. I am not even asking for Safari on Windows, but Apple needs to up or sustain its current development and give it more time. Especially memory resources usage and multi tab operations.
ksec··on Firefox Enterprise
20 years later they are finally taking Enterprise seriously. I still remember how hard it was to push Mozilla just to support Windows Group Policy along with other enterprise requirements and they were simply not interested in enterprise. Even though later they did some bare minimum to support it.
ksec··on Solar surpasses nuclear power globally for first time
China themselves could have installed all of that capacity. But they are limited by batteries and other infrastructure and are catching up to those while planning a bigger play in the dessert solar farm.

They plan to increase 50% for Wind and Solar in 5 years, and possibly double in 10 years. Since 80%+ of all future planned Nuclear reactor are also in China, they would have more than double their renewable energy in 10 years. China is the number one in electricity production and usage, more than twice the size of US and 33%+ of the world. Given the size of China this is both exciting and scary.

ksec··on JPEG XL vs. AVIF for web use-cases
>now there are comparisons popping up showing how AVIF actually compresses better.

You perfectly summarise how I felt as well. The revisionist also tries to paint the story as JPEG XL was first banned due to security issues which is again not true.

But that is OK. Since JPEG XL has finally and rightfully won its place, mostly thanks for Safari. We can now hopefully wait for better encoder.

ksec··on Apple routed a graphite pipe through the iPhone Duo's hinge to dissipate heat
It wasn't always the case with software, before the internet era and updates. Software were done with a lot more cares because burning discs and distribution were costly. Exactly the same reason why Hardware put a lot of thoughts into it for failure because recalling product is expensive.
ksec··on Apple routed a graphite pipe through the iPhone Duo's hinge to dissipate heat
I think you just happen to have the worst era in MacBook hardware. Happening 2015 - 2020. It has gotten better or back on track since then.

Keyboard is finally back to semi decent now. The old scissor is still better. But I think 2024 or 2025 they finally make some minor changes that is closer to old scissors.

ksec··on JPEG XL vs. AVIF for web use-cases
Thank You. I was about to post I suspect both of those images would have worked better with JXL lossless.

Curious what is the better encoder here referring to?

ksec··on JPEG XL vs. AVIF for web use-cases
I don't get it. And to me it wasn't clear in the post. As others have explained the container and codec are two separate issues.
ksec··on JPEG XL vs. AVIF for web use-cases
That was done before AVIF had any improvements. Arguably one could even say JPEG XL competition brought the best of AVIF out.
ksec··on JPEG XL vs. AVIF for web use-cases
It extracts the already quantized DCT coefficients and related data from the JPEG bitstream and re-encodes them with JPEG XL’s more efficient entropy coding and container,

Think of it as zip compression that is specially designed for JPEG and putting the JPEG data in a different/better container.

ksec··on JPEG XL vs. AVIF for web use-cases
AVIF ( or even AV1 itself ) has had massive increase in quality improvements over the past 6 years. JPEG XL was close to release in 2020 and finalised in 2021. A lot of the sentiments hold true back then.

JPEG XL has always been targeting high quality encoding metric first before the lower end low BPP images, which AV1 excels at with or without the last 6 years of improvements.

The current top comments about MP3 and LAME is again about how encoder extract maximum potential. JPEG XL was may be the best in 2021, but has been fighting for survival since then.

There a lot of different images that JPEG XL encode better. Screenshots with text is known to be not something they have optimised for or think it could be good at. Lossless mode may be better. Edit: As one of the other comment here proved my point.

Had all of these, even just a hint of AVIF improvement be told, may be the sentiments would have been a little different. But then again I am not one who would trust the same people who sold me WebP and AOM roadmaps.

But at least AV2 is coming. And JPEG XL is finally in every browser. Hopefully we can all have something even better in the future.

ksec··on Apple may have an iPhone 18 Pro demand problem
I thought Apple did poorly in this year 18 Pro Marketing.

The A20 Pro was a massive jump in performance per watt, meaning higher efficiency. A lot of site that latter discovered what A20 Pro were doing thought Apple under sell its achievement.

They should have provided battery life compare to 14 Pro and 15 Pro. Which is anywhere from 30% to 40% more. That is a huge jump and a lot of people are still on 13 - 15 range. That single reason should have pushed an upgrading cycle alone.

Every other phone has increased their price for a lot more in terms of percentage. Apple is actually on the lower side especially to entry model. Some how this message should have been marketed. A lot of iPhone user aren't aware that Android have gotten a lot more expensive as well for their flagship.

ksec··on Apple may have an iPhone 18 Pro demand problem
I would expect the 18 Pro to have 30% more battery life if not more compared to 15 Pro on a new battery.
ksec··on Our $445M Series D
>we're paying taxes because we're profitable.

I guess the question is why not invest those profits to further expand when there are already a backlog of orders to fill.

But on the other hand Huge Congrats being a profitable company! Hardware business is insanely brutal, and having the backlog is great to hear. AMD being investor I hope you guys get Zen 6c and Zen 7c earlier in the future.

ksec··on Cloudflare acquires Deno
>but there is nothing to “win” here.

In the context of Deno here, it obviously implies market share.

ksec··on Shipping JPEG XL in Chrome
1. Not true before modern AV1 encoder got major improvements in the past 3 years. There is no reason why JPEG-XL can't be improved in the low bpp range. JPEG itself got improvement 20 years after its initial introduction. Not to mention the last time I check, JPEG XL is still better at high end fidelity.

2. JPEG XL lossless can be 10-13% or in some cases up to 50% better. Of course WebP could also be better in some cases. And again, JPEG-XL potential is far fully optimised. Both in encoder and decoder.

On another note, the AOM camp should really have played the AV2 card suggesting it to be better.

ksec··on Shipping JPEG XL in Chrome
Just want to say thank you for keeping the record straight. I am too late to this thread.
