spintin··on Multi-Threading and Mutation
Or you just go with "arrays of 64 byte multiple atomic structures" and you get parallelism and cache!
spintin··on Tenstorrent unveils Grayskull, its RISC-V answer to GPUs
I bought a 3050 low profile / half length with DDR6 at 14GHz for half this price.

And it can play games too.

spintin··on S3 is files, but not a filesystem
Correct me if I'm wrong but bitrot only affects spinning rust since NAND uses ECC?

If you see this I wonder if S3 is planning on adding hardlinks?

spintin··on Obsolete Occupations
These are not obsolete, I'm a coffee sniffer too.
spintin··on My AWS bill got larger with VPC
Yup, that was it.
spintin··on My AWS bill got larger with VPC
What is VPC and how can they launch a cost feature for me without asking if I want to pay for it?
spintin··on HDMI Forum does not allow an open source implementation of the HDMI 2.1 spec
I recently discovered you cannot pass 75Hz over DVI -> HDMI -> DVI!

For some reason the bandwidth is too low?

So for 60Hz there is interop. but for 75Hz you need a thick DVI cable.

spintin··on Bluesky is rolling out Hashtags
I'm perfectly prepared to do that as I did yesterday with Add Link Card BUT I need bluesky to SHOW the damn .gif and not have users have to click on a URL!!!

It's a one second change.

Add link card? Ok buddy!

.gif is better than video if you have a small area that changes on the picture frame by frame.

.gif can handle transparency.

.gif will never be obsolete.

Also dithering is an aesthetic!

spintin··on Look, ma, no matrices
This is hair splitting at the end of progress:

The fact that 3D skeletal animation is still using 4x4 matrices in the GPU means the math developed for this around Half-Life 1 (on CPU?) is still the bleeding edge. 1998 -> 2024 = 26 years!

In 1000 years 3D animation will still be the same. End of story.

spintin··on Bluesky is rolling out Hashtags
Wrong prio: videos and animated .gif is 100% the ONLY thing anyone at that company should be spending ANY time on.
spintin··on Micron Kicks Off Production of HBM3E Memory
This is an empty article:

- CAS latency?

- Wattage?

Also: https://piped.video/watch?v=2G4_RZo41Zw (is this memory same size as 5nm?)

spintin··on Pains of building your own billing system
You should never build your own billing system because you do not want to do the global VAT work.

itch.io is a good alternative if you sell digital assets and even services as you can verify payments with mail.

spintin··on I don't think the cheapest APC Back-UPS units can be monitored except in Windows
Inverters have losses (~10%), you need 12v devices for this to work.

PicoPSU is the way I solve this.

spintin··on Nvidia hits $2T valuation as AI frenzy grips Wall Street
yes
spintin··on I don't think the cheapest APC Back-UPS units can be monitored except in Windows
It's better to just build your own with a 12v charger, a few 12v lead acid deep discharge batteries in parallel and a 9-18v -> 12v aligner.

If you live in EU go with 110-220v charger so your setup can outlive a brownout.

spintin··on Nvidia hits $2T valuation as AI frenzy grips Wall Street
People don't get it: it's not AI that is valued high, it's the dollar that is worthless.

If the US wants to win in Ukraine it needs to print like a mad man, look at the SPR; it tells you the truth (albeit with 3 months lag for mere mortals).

This is the end game, no matter what the eternal growth crowd says.

How money (and empires) die.

spintin··on If architects had to work like programmers (1995)
The biggest thing missing from this is you have to build a brick house with a hammer and nails or a wooden house with mortar.

The premise of micro-services where lost in complexity, the whole point always was "you should be able to select the tools you like".

spintin··on SSDs have become fast, except in the cloud
I'm going with hybrid:

- 2011 X-25E 64GB (2W write and almost nothing read/idle) at 100.000 writes per bit for OS

- 2021 PM897 3.7TB (2.3 Watt (read) ¦ 3 Watt (write) ¦ 1.4 Watt (idle) down from the PM983 (8.7 Watt (read) ¦ 10.6 Watt (write) ¦ 4 Watt (idle)) for DB.

This way I can get the most robust solution, with largest DB at lowest power. They are both in a 8-core Atom Mini-ITX board at 25W TDP.

spintin··on Considerations for a long-running Raspberry Pi
You need to factor in usage, if you are idling a lot ARM > X86.

And you need to look at longevity, there I suspect ARM will outlive X86 too.

For modularity ARM > X86 too, because they are cheaper to have many small of.

But for scalability (= business in the current economy) X86 > ARM.

Also all graphs should be per watt, that 2 -> 4 is more performant is not news, that it is more performant per watt is!

And if you did that you would see that Raspberry 5 is not getting as much per watt performance increase as it should.

We have peaked permanently for the eternity of mankind.

Let that sink in.

Last but not least, the ONLY hope for any progress (openness not performance) at this point is the JH7110, but they are lagging behind in 3D support.

spintin··on Considerations for a long-running Raspberry Pi
I have been running a Raspberry 2 cluster for 10 years.

A few weeks back the first SD card to fail got so corrupted it failed to reboot!

My key learning is use oversized cards, because then the bitcycling will wear slower!

I'm going from 32GB to 256/512/1024!

That said "High Endurance" cards are a scam, they fail way quicker than regular cards!

All SD cards except SanDisk have latency problems. There is no competition.

If you can get SLC SD cards use them for workload instances = no db or file storage.

Re-inventing the wheel is not the problem. It's copying the wheel that is the problem.

spintin··on I'm Done Punching Trees and Grabbing Rocks in Video Games
The tree is the quintessential UGC (user generated content) concept, there will never be a better way to communicate harvesting/building mechanic.

But the real end goal is to make the world persistent across thousands and hopefully 10s of thousands of real-time action players.

The problem is that we now have billions of humans building non-persistent and pervasive worlds that disappear!

spintin··on Why do people post on [bad platform] instead of [good platform]?
I think the best way to use "social media" is to pull eyes to your own platform, eventually people will transition (Myspace -> Facebook -> Reddit -> Twitter -> Mastodon) and each time they move the likelihood that they eventually use "RSS" increases.
spintin··on The Future of Memory
Yes, but the cost in terms of watt and manufacturing are not scalable.

Also most programs have cache-misses.

spintin··on The Future of Memory
Above 64GB you need registered RAM increasing the latency.

So as you increase bandwidth you reduce program speed.

Higher frequency results in more heat.

We are fast approaching the need for a Wii like Broadway architecture where the program is running in "fast" SRAM and the data is on "slow" DDR.

spintin··on Mourning Google
"If we are going to be destroyed by an atomic bomb, let that bomb when it comes find us doing sensible and human things — praying, working, teaching, reading, listening to music, bathing the children, playing tennis, chatting to our friends over a pint and a game of darts — not huddled together like frightened sheep and thinking about bombs. They might break our bodies (a microbe can do that) but they need not dominate our minds." - C.S. Lewis
spintin··on Comparing the 1970's Cray-1 supercomputer against the Raspberry Pi
We now have a C64 as powerful as the Cray-1 is what you could say if you traveled back in time.
spintin··on Ask HN: 9-yo son wants to build a game, I'm lost. What can I do?
I would say begin with 2D and code it in Java from scratch with Graphics2D.

This way you focus on the ideas and build something usable at the same time.
