nodesocket··on Afterglow: Run classic After Dark screen savers on modern macOS
Is there just the one Mowin' Man in More After Dark?
nodesocket··on New Mac mini, featuring M6 and M5 Pro
True but memory bandwidth is not the entire story. Geekbench (while not a end-all benchmark) shows:

                      Single-Core      Multi-Core
  M1 Max, 10-core     2,204            14,004
  M4 Pro, 14-core     3,311            24,711

Single-threaded CPU: M4 Pro is roughly 1.5× as fast. Multi-threaded CPU: M4 Pro is roughly 1.75× as fast. GPU: roughly equal to a full 32-core M1 Max, with the M4 Pro slightly ahead in Geekbench Metal.

Obviously the M4 Pro feels faster.

Optimus ins’t gonna be a master welder, electrician, HVAC technician, general contractor anytime soon.
nodesocket··on Show HN: Lightweight system monitor for Linux VPS written in Go
If anybody is looking for alternatives, I’m a very happy user of Bezel (https://beszel.dev) on my home lab servers including a Raspberry Pi Kubernetes cluster and TrueNAS. Highly recommend.
nodesocket··on New Mac mini, featuring M6 and M5 Pro
I also can feel a speed/sluggishness difference between my M1 Max MacBook Pro and my M4 Pro (14 core).
nodesocket··on New Mac mini, featuring M6 and M5 Pro
Upgrading to 48GB memory is $600…. Gut punch. I have a M4 Pro (top cpu skew 14 cores). Any idea the performance gain to M5 Pro? I feel like they holding off releasing M6 Pro because a new studio is dropping soon as well.
nodesocket··on DEF Con 19: Skunkworks: Daniel Beckwitt on Bitcoin in 2019 [video]
At time of his talk Bitcoin was trading at around $8. Let that sink in.
nodesocket··on Field measurements of neighborhood-scale air temperature impacts of data centers
There a few factors at play. I believe China has launched a very successful campaign of misinformation in order to slow down US progress and allow them to “win” the “AI War”. Then climate activists and let’s be frank far left leaning people have taken the bait hook line and sinker and amplified it.

Second Anthropic at the start was very vocal about datacenter doom. Their motivate besides wanting regulatory capture is again slow down their competitors and corner the market.

Lastly mainstream media loves a good doomer story of tech people getting rich displacing working class Americans while “destroying earth”.

nodesocket··on Show HN: Write.md – A free, open-source, themeable Markdown editor for macOS
Paying Typora user here, and wondering the same.
nodesocket··on U of Michigan drops first-semester grades to ‘curb mental health crisis’
This sort of coddling and weak policy is setting students up for a rude awaking when they get into the professional workforce.
nodesocket··on Hyperspace
Seems useful for s3 buckets. I suppose a script that watches for new objects, calculates its sha256 and stores that in a DB, then checks for duplicate hashes would be a fairly trivial task. Though s3 doesn’t support symbolic links so accounting would need to be handled by server side code.
nodesocket··on Timeline of the OpenAI accidental attack against Hugging Face
It’s absolutely wild that agents used a write access oversight in their package manager to communicate amongst themselves. It essentially created an agent ad-hoc chat interface using their own package manager file system.
nodesocket··on GitHub Actions and Pages are experiencing degraded availability
Also use Blacksmith for arm64 runners but this outage apparently affected webhooks so their runners are not picking up jobs either.
nodesocket··on Getting 25 Gbps Thunderbolt Ethernet on My Mac Studio
I predict the next generation of Studio’s will have a 25 Gbps upgrade option built-in.
nodesocket··on Launch HN: Prized (YC S26) – Let non-engineer staff build secure internal tools
Congratulations on the launch. I’m very bullish on this concept of allowing SMB’s and startups to roll their own software and internal tools. Many many moons ago I built an entire inventory tracking and CRM for a very small company in PHP (circa 2006). It ran the entire company with orders, customers, devices, and revenue. It was a monstrous app, and took forever. Today, could be build in a matter of days and much better.

Along the same lines. I got so fed up with Quickbooks self employed (god awful software and company) for my own business I wrote a replacement using Cursor. It tracks expenses (categorizing each in proper IRS categories) and estimating quarterly taxes. Uses Plaid to pull in business bank accounts and credit cards and has income and expense reports. It’s 100x better than Quickbooks.

nodesocket··on GitHub Outage
I suspect all the good devops engineers left when GitHub was acquired by Microsoft. They got their pay day and living on a beach somewhere.
nodesocket··on GitHub Outage
My docker container builds have been queued for nearly an hour.
nodesocket··on Ask HN: What Are You Working On? (July 2026)
Replacement for Quickbooks Self Employed (which is awful). Integrates Plaid and allows you to categorize business spending by official IRS categories and business income. Graphs of business spending, income, profit by month, quarter, and year. Export to CSV for easy entry into schedule C at tax time.

Future feature is estimating quarterly taxes and showing approximately how much should be paid each quarter if any and due dates.

nodesocket··on Mapping homes you can buy from the US government for <$100k
Tempting if looking to build a new workshop or garage. Tear it down, and build from scratch.
nodesocket··on Mechanical Watch (2022)
Be warned, once you get into mechanical watches it can be a debilitating addiction. :-). I started out with a Tag Heuer Aquaracer Professional and then sold that to buy an Omega Seamaster Diver which I love. I’m lusting for a Audemars Piguet Royal Oak but that’s a ways off.
nodesocket··on Open source AI must win
It all comes down to financial incentives. Unlike the internet and software where the barrier to entry was essentially free. Open source frontier models are extremely capital intensive, infact virtually impossible without hordes of money and power. So where are the incentives for investors to back an open source model? There isn’t any. The exception is Meta because they have so much capital they can endure the loss, but they have fumbled Llama.

Another potential player could be Apple if they open sourced a frontier model, and make back some of the capex on hardware. Imagine AIserve hardware with continued expansion of MacMini’s and Mac Studios.

nodesocket··on If AI data centers are so great, why are they being built in secret?
Microsoft CEO Nadella just recently said their Fairwater (315-acre facility in Wisconsin) only uses around the same amount of water as a single restaurant over the course of an entire year.
nodesocket··on If AI data centers are so great, why are they being built in secret?
25 data center projects were canceled in 2025, up sharply from only 6 in 2024. 2026 numbers gonna be dramatically higher. 69 jurisdictions have enacted some form of moratorium, ban, or restriction on new data center construction. The friendly states such as Texas are just going to have all the data centers and thus reap all the financial and job benefits.
nodesocket··on The Public Should Own Half of the Big A.I. Companies
The quickest way to lose the AI battle to China and reinstate censorship and model political bias is to hand the industry over to the government. This doesn’t just benefit democrats, whatever political party is in power will use them as tools of political means. Not to mention almost certainly pricing won’t act in accordance with free market forces but instead be regulated. See healthcare.
nodesocket··on If AI data centers are so great, why are they being built in secret?
One reason is that politicians have vilified them for their own political means. Creating false narratives like they use huge amounts of water, when in fact the cooling is a closed loop system and use less water than a single busy restaurant. They are being used as yet another pawn piece to push inequity and climate change agendas. It’s been quite a successful strategy.
nodesocket··on SQLite is all you need for durable workflows
Ahh that's very nice. Unfortunately the default version of sqlite3 provided by Debian Trixie is 3.46.1.
nodesocket··on SQLite is all you need for durable workflows
The biggest annoyance about SQLite for me is no ability to:

    ALTER TABLE users MODIFY COLUMN…

    ALTER TABLE users ALTER COLUMN…

    ALTER TABLE users ADD CONSTRAINT…

You have to create a new temporary table with correct schema, copy data into this new table, drop the old table, and then rename the temporary table.
nodesocket··on OpenAI Is Preparing to File for an IPO Soon
Smart move IPO'ing ahead of Anthropic. Can take a lot of AI capital being first mover... That is, until Anthropic IPO's which I expect shortly.
nodesocket··on The main thing about P2P meth is that there's so much of it (2021)
Heisenberg lives? The king of P2P with 99% purity.
