benjaminl··on How SpaceX streamlined the Raptor engine
Tony Bruno, when referring to the partially assembled engine, was complaining about the lack of engine controllers, fluid management, and TVCs [1].

In addition, SpaceX isn’t cheating by not including TVCs. They purposely designed their rocket to need a minimum of them and fully take advantage of the space savings the lack of TVCs affords them.

[1] “So, there is no need to exaggerate this by showing a partially assembled engine without controllers, fluid management, or TVC systems, then comparing it to fully assembled engines that do.”

benjaminl··on Where did the old web go? We followed 657,607 links to find out
For me the old web is when people still had homepages. When those went away, the old web died.
benjaminl··on Linux desktop market share has hit over 10% in North America
It’s still really strange that Linux is several times larger than ChromeOS. I would not have guessed this. And I daily drove Linux for years.
benjaminl··on Africans Are Turning to Starlink
The parent is correct. Look up have many antennas are on each Starlink sat. There are multiple dedicated antennas for customers and ground stations. There isn’t just one antenna or beam per satellite.

Also, lookup the number of ISLs in orbit. Starlink has been providing coverage for the middle of the ocean for years now. They have provided coverage to Pacific Islands that have lost their undersea cable connections.

benjaminl··on Why Ctrl+V won't paste images in Claude Code on WSL, with a fix
Ctrl+V paste works for me on WSL. My secret is that I have given up on WSLg and use a standalone X Windows server. Specifically, the X410 X Server. This removes a whole lot of weird behavior including the ones described by the article.
benjaminl··on ARC-AGI-3
This issue here is that people have different definitions of AGI. From the description. Getting 100% on this benchmark would be more than AGI and would qualify for ASI (Algorithmic Super Intelligence) not just AGI.
benjaminl··on 10% of Firefox crashes are caused by bitflips
In just about every way. CPU caches are made from SRAM and live on the CPU itself. Main system RAM is made from DRAM and live on separate chips even if they are soldered into the same physical package (system in package or SiP). The RAM still isn't on the SoC.
benjaminl··on TPSV, an Alternative to TSV (and CSV)
The spec says that the first row specifies the number of columns.
benjaminl··on "No way to prevent this" say users of only language where this regularly happens
The story is satire. But the satire is illustrating true problems and attitudes.
benjaminl··on Pytudes
Kinda hard to answer as that depends on your definition of new. But most likely yes, https://github.com/norvig/pytudes/commits/main
benjaminl··on Tailscale vs. Narrowlink
They should move to using QUIC which is the protocol backing HTTP/3. QUIC incorporates TLS1.3 and has an extension for UDP style unreliable datagrams (https://datatracker.ietf.org/doc/rfc9221/). It would be the perfect way to bring SSL/TSL/HTTPS VPNs onto a modern performant protocol while keeping the simplicity in of the https based VPN. It would still have the advantage of looking like https traffic, while have the performance characteristics of UDP based VPN protocol.
benjaminl··on GPT-4 can't reason
GPT-4 gave me a concise correct answer without disclaimers.

This may be due to using many custom instructions like the following in ChatGPT settings:

- No need to provide disclaimers about your knowledge cutoff

- No need to mention you are an AI language model

- Only discuss safety when it is not obvious and very important

- You should act as an expert in the relevant fields

benjaminl··on The "specialness spiral" leads us to not use some ordinary objects (2021)
I also buy the most expensive Apple phone and not put it in a case. My experience is quite different from your, perhaps unintentional straw man. Let’s take this assertion by assertion.

> I put my (slippery) iPhones in cases because if I don’t they stop working. Your phone might not care that its screen is cracked

I would be hugely bothered by a cracked screen or an otherwise non-operative screen. But Apple’s Pro level phones feature steel cases. This makes the phone very robust. I have yet to crack or otherwise damage my phone.

> have to pay several hundreds to put it back the way it was vs spending 20$ or less on a case and screen protector

Always get AppleCare Plus. It serves as my screen protector. If I ever did crack my screen service fee to fix a broken screen is $29.

> which takes 10 minutes vs having to pay 100x as much and wait a few days to get my phone back to swap displays

As per above the price difference between a case and AppleCare is minimal close to 0x as much.

And it doesn’t take days to have your screen replaced. Apple stores will do it in minutes within the space of a single service appointment.

iPhones are truly works of art and should be enjoyed without cheap plastic cases. Just make sure you have AppleCare Plus.

benjaminl··on Norway: Landlines will no longer be supported
Analog telephones have terrible bandwidth. Just 300–3,300 Hz. This it technically called the voiceband, but it cuts off a good portion of female speech.

Also, all phone lines these days, wether POTS or VOIP are digitally trunked and switched.

benjaminl··on Court overturns state ruling on San Francisco’s infamous 469 Stevenson project
Normally that is the case, but California has been very active passing significant housing reform legislation in the past couple of years. Just this last legislative session over 20 housing bills were passed: https://www.hklaw.com/en/insights/publications/2022/10/calif...

The problem is that city counsels and judges are skirting laws by violating clear legislative intent.

benjaminl··on We built voice modulation to mask gender in technical interviews (2016)
Yeah, pitch is only one of the components of speech pattern differences between genders. Others include resonance, intonation, rhythm and more.

Ask a trans person and they will tell you that changing your perceived speech gender is much more than just the pitch.

benjaminl··on Sex Redefined (2015)
The problem is that a certain segment of society is passing laws insisting that everyone neatly fit into 2 distinct buckets. Also, insisting that the bucket you were categorized in at birth is immutable. They are using the phrase “biological sex”, where as this paper shows, that concept is both ill defined and messy.
benjaminl··on Scientists have finally found the potential “cure” for baldness
The linked article appears to be entirely copied from the University of California press release. https://news.ucr.edu/articles/2022/07/25/chemical-controllin..., which is a much better source of information.

Also, here is a link to the actual paper published in Biophysical Journal.

benjaminl··on Fuchsia Workstation
Since the build page doesn’t provide much context, Fushsia has 3 different configurations bringup, core and workstation.

The workstation configuration is described as:

> workstation is a basis for a general purpose development environment, good for working on UI, media and many other high-level features. This is also the best environment for enthusiasts to play with and explore.

benjaminl··on How SpaceX lands Starship (sort of)
The YouTube show How to Make Everything. Did this. They started the tech tree from the very beginning by making simple hand stone tools and then building up tool by tool to more sophisticated technologies.

If all you have is a hand. Even getting the wood to make a handle for your axe is hard.

benjaminl··on SSH and User-Mode IP WireGuard
With the coming ubiquity of QUIC, its seems natural to have a QUIC based analog to OpenVPN using packet based QUIC instead of OpenVPN’s UDP/TLS.

It also seems rather obvious to extend WireGuard to run over QUIC in addition to UDP. But the movement on that front has been very limited.

benjaminl··on A request for Pinboard old-timers
If Pinboard is being maintained, this is great news. I had thought it was abandoned and I have been looking for alternatives.

My biggest pain point is the lack of maintained iOS clients.

benjaminl··on Ask HN: How to increase SWE salaries in Europe?
Don’t forget the 10.25% sales tax. This puts the combined marginal tax rate at 59.85%. (24 + 9.3 + 7.65 + 7.65 + 1 + 10.25)
benjaminl··on Asahi Linux: Linux on Apple Silicon project
Windows on ARM supports 64bit ARM apps.

What you were possibly remembering was that Windows on ARM when it was first introduced only supported emulating x86 apps. Although x64 emulation is currently in preview.

benjaminl··on Peak Oil Is Suddenly Upon Us
That US oil self sufficiency means that it will get out of the Middle East is a key part of Peter Zeihan’s Disunited Nations. His premise is that the US will disengage from the world no matter who won the election and that will have far reaching ramifications for the world.

A major reason of the ability for the US to do this is energy self sufficiency.

benjaminl··on Micro Magic RISC-V Core Claims to Beat Apple M1 and Arm Cortex-A9
They are making these claim using the EEMBC benchmark. This must be an interesting benchmark as they claim the fastest chip on the EEMBC benchmark is a Cortex-A9, a 8 year old design.
benjaminl··on Why is Apple's M1 chip so fast?
Unlike what has been said on Twitter the answer to why the M1 is fast isn’t due to technical tricks, but due to Apple throwing a lot of hardware at the problem.

The M1 is really wide (8 wide decode) and has a lot of execution units. It has a huge 630 deep reorder buffer to keep them all filled, multiple large caches and a lot of memory bandwidth.

It is just a monster of a chip, well designed balanced and executed.

BTW this isn’t really new. Apple has been making incremental progress year by year on these processor for their A-series chips. Just nobody believed those Geekbench benchmarks showing that in short benchmarks your phone could be faster than your laptop. Well turns out that given the right cooling solution those benchmarks were accurate.

Anandtech has a wonderful deep dive into the processor architecture.

https://www.anandtech.com/show/16226/apple-silicon-m1-a14-de...

Edit: I didn’t mean to disparage Apple or the M1 by saying that Apple threw hardware at the problem. That Apple was able to keep power low with such a wide chip is extremely impressive and speaks to how finely tuned the chip is. I was trying to say that Apple got the results they did the hard way by advancing every aspect of the chip.

benjaminl··on It’s time to remove news from Facebook and Google
Towards the end of the post we find out why they want to block news links from Facebook and Google, they are setting up a competing platform.

“That’s why we’re building Forth, a news-first platform that pays journalists for their work and offers the audience concise updates with context -- from the reporters they trust. All revenue generated on Forth is shared with our news partners.

We only allow trusted and credible journalists (vetted by our editorial team) to publish to the platform. It's a one-stop shop for accurate information about what's happening right now.”

benjaminl··on Why do printers still suck?
My color laser provided significantly better color than any of the inkjet I have used. It provided nice even color. Whereas the inkjet color was often banded.
benjaminl··on Chromecast with Google TV
The tech specs say it is running “Android TV OS”.

It is a rebranding and the new direction of Android TV. (https://arstechnica.com/gadgets/2020/09/google-merges-chrome...)

> “But while Android TV is the foundation of the new Chromecast, the whole experience feels very new. Because unlike TVs from Sony and set-top boxes from Nvidia and other brands that run the traditional version of Android TV, Google has created a new “Google TV” layer atop the operating system that completely replaces the old home screen experience.”
