ksec··on GPT-6 Sol and Luna
I am starting to wonder if this test is now being heavily benchmarked internally we should be using some new test?
ksec··on Apple has added persistent 'ads' to iOS, and it's driving users crazy
>Recently I am starting to question some of the design decisions. Most native apps are bloated with functionalities,

The whole iOS and Android keep copying each other and without someone like Steve being the editor they became pretty similar.

I want an iOS that is SIMPLE. And the software Apple is offering right now is anything but simple. Homescreen is now clustered mess. And for every banks, resturatnts all want an App for themselves, either you skip all the discounts and functions or now you have more clutter to deal with.

ksec··on How did AMD Ryzen get 50% faster in two years?
Perhaps better looking at it without the 3D Cache on GB6 scores.

2020 Zen 3 AMD Ryzen 7 5800 - 1852

2024 Zen 5 AMD Ryzen 9600X. - 2914

2027? Zen 6 - Est 3200?

And compare this to Apple.

M6 4000+

M5 3600+

M4 3300+

Even the Snapdragon X2 Elite X2E is better at 3300.

The gap isn't exactly shrinking. And I would love x86 to prove me wrong. But even a hypothetical Zen 7 in 2028 ( 2029 for consumer ) may only catch up to Apple's M5 released in 2025.

ksec··on How did AMD Ryzen get 50% faster in two years?
Yes I stated that as well in the previous comment [1] on how Apple got 50% faster in 3 years.

>Compared this to the article "How did AMD Ryzen get 50% faster in two years?" The Zen 3 uArch being used in the article came out in 2020. So it is more like AMD got 50% faster in 5 years.

Yes!

Now I am thinking how did that link got into my Copy and Paste. I checked my history I didn't even visited the link before this, nor the main thedailybeast website.

And I can't delete the entry.

ksec··on Microsoft killed FoxPro in 2007. Anyway, here's FoxPro revived
I know there are still a few niche industry that has an industry standard program written in Visual FoxPro, and I remember as pre COVID 2019 they were still using it. ( Edit: I just called and asked, still using it as of 2026 )

Niche but no small business, commodity with over $400M USD annual revenue, the industry together that is easily $2B+.

If it is not broke, don't fix it. And there are industry that is extremely conservative in anything software, they will just keep it running for as long as they could.

I used to be sad that we don't have something better to replace these antique software. Now I have come to appreciate it, mostly because newer software haven't show they have manage to add value in the slightest. And most of the time they simply don't work as well.

Delphi, Visual FoxPro, Visual Basic, Flash. I used to think one day we will have something that is not only faster, easier and scalable replacement of those. Instead everything went more technical, more complex, enterprisy and non-user friendly.

And to the Author of the project. Thank You for making it.

ksec··on Apple iPhone 18 Pro Camera test
This has been the case since iPhone X. In all previous generations Apple was always the more natural looking profile. Since then they lost to the Instagram user base demands and started this over processing photos. They walk back some of it in the past 5 years but it is still extremely over processed in my view.
ksec··on Apple iPhone 18 Pro Camera test
And it sort of reach a plateau where for normal consumer it doesn't matter much other than zoom. Which is important to a certain extend.

I wish there is some tech in the pipeline, that in the next 5 - 10 years we could get decent pictures quality without the huge bump.

ksec··on Scott Jenson: Are we going to use the same Desktop UX forever? [video]
Great Video. I think I watched something similar 2 - 3 years ago. And he basically stated ( again ) what went wrong with Apple giving Jony Ive the design of overall user interface.

ksec··on How did Apple Silicon get 50% faster in three years? – Daniel Lemire's blog
Well first A20 Pro didn't get wider, it actually shrink back to 9 decode width. It would be a lot better to compare it on the A silicon rather than M.

Second is that Apple's improvement were done when they were state of the art and leading the pack. This is a lot harder than when you are behind and being shown how much more room to grow.

The A20 Pro is the largest leap in performance in recent or perhaps in all of Apple SoC history. It doesn't get enough credit and attentions that it deserves.

Compared this to the article "How did AMD Ryzen get 50% faster in two years?" The Zen 3 uArch being used in the article came out in 2020. So it is more like AMD got 50% faster in 5 years.

And perhaps this also answer and refer back to the previous HN submission and comments as to why ARM Mac are slower on SVT-AV1 encoding. Apple's SIMD performance is still behind AVX-512. But it is for good reason though and the trade off IMO is well worth it.

I guess I learned something new everyday.

ksec··on Minimal Phone 2
Making one isn't "that" hard once you factor in China's production capabilities. The problem isn't even making it, the hardware part. ( Ignoring IP for a second )

Once you have all that, it is how do you sell it, and sell enough unit to even have a ROI. And that is ignoring UI / software.

I don't think people on HN understand, hardware business is brutal.

ksec··on Apple M6 Pro Achieves the Highest Single-Core CPU Score in Geekbench 7
I know these are all Mac CPU, but for context people may want to look at A20 Pro [1], which in 2 years time will be in MacBook Neo. Pretty damn impressive if you ask me.

A20 Pro is around 4K on Geekbench 7. And the P-Core is not the same as M6. The A20 Pro is actually only 9 wide compared to 10-wide on M6. Supposedly more power efficient and smaller die size.

ksec··on Apple M6 Pro Achieves the Highest Single-Core CPU Score in Geekbench 7
A20 Pro would have been number 1 if it was included in that chart.
ksec··on Apple M6 Pro Achieves the Highest Single-Core CPU Score in Geekbench 7
Just want to add apart from all the other comments. SVT was brought by Intel and spent years to make it extremely well tuned for x86. While not the same for ARM and not even for Apple.

Another point is that the multicore part uses all core including E-Core. On AMD the multicore are all the same. Meaning for some benchmarks this will flavour Apple more.

Again there is nothing that stop people from optimising it for ARM Mac. The problem is the usage of it is so small it probably doesn't make sense to focus on it. SVT took a really long time for it to reach quality parity with AOM's AV1 encoder and later exceed it.

ksec··on Jemalloc 5.4.0
Ok. Why both the homepage and its Github repo doesn't make a single mention of Jason Evans? I know he stepped down but surely it is at least worst mentioning it?

Is Meta still using it and developing it? If not who are the driving force behind it now? I just checked there wasn't a release since 2022 and then we have this now. Something changed?

Just wish we have a little bit of context. But it is also great it is continue being maintained. It makes a huge difference for Ruby on Rails Apps.

ksec··on Apple May Return to Server Market with Nvidia Technology
Makes very little sense to me. As much as I want a Xserve, I don't see how Apple has a competitive advantage for the target market.

Nvidia already or will definitely make a product that will compete with Apple, as they are moving towards full integration. They also owns the networking, GPU, CPU, and other parts as well. Apple's only advantage is M8 potentially being slightly faster and macOS. Neither is a moat for the intended market.

ksec··on The case against JPEG XL
Had a lot of the content in this article came out 4 years ago I would have agreed. At least we finally don't have a fake Image Coding Comparisons [1] that tries to undermine JXL.

Ignoring AOM and AV1, I was the first few on HN apart from its author supporting JXL from the start, I would argue the biggest case against JPEG XL is JPEG li.

Jpegli offer enough quality improvement and advantage without introducing an entirely new codec. And all of a sudden the bar for next image codec now needs to be even higher.

ksec··on The case against JPEG XL
>nobody else had the same interpretation as you

I do. Even though it reads as trying to as fair as possible. But remember, your title is "The case against JPEG XL".

And the rest of the article is within the context of the title.

ksec··on iOS 27, iPadOS 27, and macOS 27
People who are still on Chrome as main browser should seriously try Safari 27. Compatibility greatly improved, super speedy.

Although for some reason the AI organise tab option is not showing up on me.

ksec··on macOS 27 Golden Gate
Safai 27, which is often the only thing I look forward to when new macOS comes out. But Golden Gate feels something similar to old Mac. may be the icon redesign. But for now it doesn't feel any faster than macOS26 on my M5 MBA.
ksec··on Apple Stores Said to Lose Video Walls, Regain Dedicated Genius Bars
Basically they are bringing back the old Apple Store design.

Ever since Steve Jobs passed away and Tim Cook let others continue to make Apple Store into something different. First a high street electronics store then a fashion showroom and then a "social community" space. It wasn't until Deirdre O'Brien took charge before she start to walk back a lot of changes.

Another Good sign from John since in charge.

ksec··on Will there be a 7G?
3G to 4G was a giant leap forward and it makes perfect sense. Your parent is specifically comparing 4G against 5G.
ksec··on Will there be a 7G?
It needs to work backwards, much like Video Codec and ask what do the stakeholders really want or need?

We are closing in to rolling out the last / final phase of 5G. And yet none of the Massive MIMO on FDD is happening. We are still stuck on 32T32R, hardly that impressive considering we have that in LTE already. Not to mention the insane complexity increase from 4G to 5G. And judging from the previews of 6G that seems to be event worst.

If you ask an average user, they will tell you they don't feel much different between 4G and 5G. Yes there are capacity increase and other things. But at this stage I don't think the benefits outweigh the cost of switching. That is both from MNOs and End user perspective.

ksec··on Apple A20 Pro Geekbench Result
Apparently the A20 Pro Performance Core is a new design that is different to the M6 Super Core.
ksec··on Apple A20 Pro Geekbench Result
2027 April will be MacBook Neo with A19 Pro and 12GB Memory.

2028 April we should be getting A20 Pro MacBook Neo. But I wouldn't be surprise if they bump the price by $100 again.

ksec··on Neki – Sharded Postgres
>Kinda ironic that Planetscale built their company on open source Vitess that google built

That Youtube built. I know at the time Youtube was already part of Google but I don't think of Vitess as a Google Stack.

ksec··on Apple A20 Pro Geekbench Result
This is interesting because the single Core is even fasting that the M5 suggest the two 2nm chip might not share the same Core.
ksec··on iPhone Duo
Apparently Foldables are incredibly popular in China. They sold more foldable in China than the rest of the world combined.

I wouldn't be surprised if Apple release an iPhone Duo Max later.
