ksec··on Texas slams on the brakes for 1,800 data centers
Thank you. May be that makes more sense from a political POV.
ksec··on Texas slams on the brakes for 1,800 data centers
I wish somebody working in the field could perhaps help me, why are there even 1800 DC to be built? And this is just for Texas.

Is this 1800 buildings? Or 1800 sites? How can there be so many DC being built concurrently? Why are they not 180 or at best 18? Where are all these new appetite coming from? It can't be all AI because if only a few players are training and centralised we would have a few big AI DC only. Instead these are like the edge.

I can't quite wrap my head around these number. So do we have 18,000+ DC in US currently being built? No wonder why people are against DC building.

ksec··on Bun 1.4
While it has been used by Anthropic, the main question is if it works in other Bun's 1.3 production settings. Ignoring all the improvements, if it does work and no major bug or problems occurred, We are in for some management top down "Rewrite it in Rust" action over the next few years. And perhaps even worst, management will believe in Claude feed into Claude development.

This isn't so much about Bun or Node.js any more. It is the battleground for AI and non-AI coding.

ksec··on Go 1.27
Oh I somehow completely missed Russ left. I was rather hoping there will be a version 2 from all the lessons they have learned.
ksec··on Bun 1.4 Rust rewrite is not looking good?
All that sounds great. The promised of shipping for months that never came is a concern, comparatively speaking to history of the project and what is happening. But if we have user feedback suggest otherwise may be it is good.

For most, they are still waiting for official release so they could make their own judgment, the problem is that it is still not released. I guess we should just wait a little longer.

ksec··on Go 1.27
Do we know if Go team is working in 2.0 release?
ksec··on Ask HN: GitHub employees what's going on? Why?
This is the part Github is doing really bad at, it's PR.

Had these DATA and message been tossed around more people wouldn't be so frustrated and would be more understanding.

ksec··on A 25-year-old video patent just expired, ending a legal headache for Linux
Indeed. And it is Siemens again [1], only 5 left, and Siemens' one being 2030.

I am also interested if EVC Baseline profile will become patent free soon. Given it is built on top of AVC.

ksec··on Qwen 3.8 27B is excellent, but it defaults to overthinking things
On the RTX wattage over the years, perhaps it is important to note 5090 is nearly 20% larger die size. In terms of Pref per Watt is also a higher.

>We can finally reason with and "talk" to our hardware.

The next 10 years of computing is going to be VERY interesting. May be not just computing but everything, an even wider reach and disruption than iPhone.

Unlike iPhone / Smartphone which I thought was obvious, a computer or web browser in your pocket that basically extends the internet to anywhere. Local Model AI in our computer or pocket that controls other things opens seemingly unlimited possibilities.

I initially thought it was going to be 15-20 years time frame, with perhaps a bubble burst in between. But development of both software and hardware is accelerating.

ksec··on Super El Niño Keeps Growing as New Forecasts Reach Record Territory Ahead Winter
In other words, average temperature is higher is mostly because cold days are shorter and warmer a lot more than hot days is hotter?
ksec··on Super El Niño Keeps Growing as New Forecasts Reach Record Territory Ahead Winter
That is the question I am trying to get from the article. Will this new "keep growing" strongest ever be as bad as the one in 1877.

But it keep explaining what El Niño and Super El Niño and how it develops without giving me any context of how strong it will be.

ksec··on A third world engineer responds to “RISC-V: They should have known better”
I don't think the Author disagree with what the original article wrote. If anything everything he said seems to reassert what the original article intended to state.

And while things has died down a lot in the past few years, there is a reason why I wrote the line.

"You do not criticise The Rusted Holy Grail and the Riscy Silver Bullet."

> Request Limit: 500 per minute

I mean that is not even 10 page view per second. We are not living in 2006. Actually even in 2006 Apache with static page would have been able to handle that on a small VPS. And that is excluding CDN.

ksec··on The weekend is 100 years old
Thank you for the submission. I have long wondered if in the old days we had weekend off, and did we just work continuously 365 days?

It is not that working 365 days is hard. It is the job in today's world are very different, Muti tasking, context switching and anything but simple even in the lowest rank.

This is mentally tiring and I have also wondered if it is a recent thing. My argument is that cutting cost over the past 20 - 30 years meant what used to be a 5 person's job is now a 1 to 2 person job.

ksec··on Were Touch Bar's problems software rather than hardware?
>The missing Escape was a hardware disaster,

They actually have ESC key with a later update. Although I thought it was too late. They should have done it the next year after first Touch Bar was introduced. I believe that is not because product designer don't want to change but some part of the supply chain / operation don't want to waste money on new design so quickly.

ksec··on 160-Bay NVMe SSD 4U Server Shown at FMS 2026 Supermicro ASG-4116S-NU160R
I remember they did 32 x 32TB with 1U design many years ago. That is 1PB in 1U.

Now we are at 20PB in 4U. Or 5PB in 1U.

This is using Solidigm D5-P5336 122TB drive which was announced in 2024. We expect to have 256TB [1] by end of 2026 based on 200 This would put this at 40PB or 10PB per 1U!

These are all based on ~250 layer NAND. SK Hynix intend to ship 375 NAND by end of 2026, with 480 to 600 between 2028 and 2030+. i.e We could see another doubling of capacity by 2030.

In 2020, Backblaze reached 1EB, or 1000PB. What used thousands of PODs, and hundreds of racks. By 2030 it be could be fitted into just 1 Rack. The magic number is 625TB per drive, we will reach 1EB per Rack.

ksec··on RISC-V: They Should Have Known Better
This and exactly this. If there is anything I learned in the past 15 to 20 years, I doubt it will be any different. The mentality of development is just different.

I want the iteration of the product that is in its 2nd or 3rd official iteration. Where you have a lot of learning done and battle tested. Preferably without the backward compatibility to create something truly beautiful. Would it be perfect? Of course not. But it will be Great.

I so wish ARM had some counter offering. They might as well give away their their low end design for free.

You might want to try Odin.
ksec··on Bluesky's active user base is shrinking as its focus expands beyond the app
Because they are regional specifics, twitter or X is only big in some countries like US and Japan. Threads is doing what twitter should have done but for the rest of the world who didn't jump onto twitter.
ksec··on Pixel Watch 5
The most important thing I bought it for was Health Tracking. Although I still don't understand why it ask me to do tacking sessions when I am simply walking faster.

2nd most useful feature is vibrate alarm.

Telling time not even that important on my list.

I don't do payment with watch. Since I think the motion of making my wrist to the counter is awkward. Since we are always on our phone it doesn't make it much simpler.

It may be easy to install battery for house, but I wonder about apartments?
ksec··on A 10M IOPS Kioxia GP1 SSD Shown Running at FMS 2026
Every time there is a discussion about Optane on HN I have always said a properly tuned SLC SSD would have provided 80-90% of the performance without the cost associated with it. And the question were always "Show me one".

There isn't one simply because there was't ( yet ) a market for it. Now we have, we also have SLC and may see a come back of Z-NAND ( Samsung specially tuned SLC ).

With the insane money going around AI. Hardware industry is finally enjoying some decent profits and can afford to spend more on R&D. Looking at PCIe 7.0 with 100M IOPS and 100*GB/s next year.

ksec··on Apple Pay Chief Jennifer Bailey Retiring in October
Getting those done in 12 to 15 years is not exactly a high achievement by Apple's standards. I have long thought and written on HN how Apple Pay, Wallet, Apple Cash, Apple Card is under developed.

So this is another nice direction which is hope is part of John's big plan.

On another note: A lot of these personnel changes is happening under the last phase of Tim Cook as CEO. I seriously doubt this is Tim's plan given his past 10 - 12 years of management restructure and HR. My guess is likely the new structure and people are picked by John while happening ahead of time under Tim to speed up the whole transaction. And it is likely something John requested.

If that is the case, this is another win of my vote for John.

ksec··on Apple Wants to Charge Developers Up to 15% for Linking Outside the App Store
I have been calling for the roughly same rate reduction since 2014, apart from the small business programme because 5% would essentially be free once you factor in fraud protection and credit card charging fees etc.

In hindsight, it is great that they milk it for an additional 12 years. But the part I still don't understand is their insistence to not break out Games into its own Game Store. Gaming represent ~80% of the App Store Revenue. They could have kept it at 30%. While lowering the rest to more reasonable trucks as suggested here.

Instead they keep dragging it on and make the pricing structure extremely complicated with different "program".

ksec··on 200 Milliseconds
May be your cafeteria was doing offline processing, while other were doing it online?

But even offline there are huge differences, say Visa / Mastercard EMV and Suicia's Felica in Japan, where the whole transaction finish in 150ms.

There were previously some work where they try to get it down to 50ms, I don't know if they are still working on it or has abandoned it.

>It’s like claiming that a company that goes from making $1 to $1k to $100k to $1mm in a 4 year period has decelerating growth.

Because it is decelerating growth. There is a reason why we use YoY percentage in annual and financial reporting.

>when a 1t param model runs off a $200 SSD instead of a $50k rack of Nvidia chips.

I am 100% sure this won't happen in 10 years time. At least not on a $200 SSD. But I wouldn't be surprised if it ran on $1K to $2K HBF SSD. It will still be better than a $50K Rack.
