Is there a reason to advertise Tikz like this?

I think I'm agreeing with you but its also not something easily dismissed. The DRAM Cartel has been found to be distorting the market on numerous occasions by various regulatory bodies. There is a boom-bust cycle that occurs with DRAM and Flash memory. The Cartel claims they always lose despite the fact that demand seems to always steadily rise.

The pandemic caused once such boom-bust that resulted in a rather large downturn in demand in 2022-2023 referred to as the pandemic hangover. During that time demand dropped following overspend during the pandemic and members of the cartel drastically cut production at times to keep prices above cost. Even after the demand recovery began in 2023, the cartel members were slow to increase production and made little to no investment in production capacity in 2024-2025. Creating a shortage.

The AI hype cycle has exacerbated the shortage by creating speculative purchases and then panic buying. Remember the shoe company that pivoted to AI?

So Cartel market manipulation is partially to blame for the over 100% increase in prices and the shortages.


He said complicated code bases. LLMs are great at producing small snippets of code to address very targeted problems.


Great on small snippets of code, passable on larger pieces of code, great at finding vulnerabilities in large pieces of code, terrible in Zork. All-in-all, a jagged frontier that defies a simple sarcastic characterization.


Very kiki, not very bouba, as Aphyr rightfully stated.


I'm sure that photo was chosen rather deliberately to garner support from a wide cross selection of grey beards.


What if you're waging a war in the name of defense?


Then you're waging a war.


What if it's just a "military operation" or a "military excursion"?


This is what they should have been doing all along. My Pixel tells me that charging above 80% is bad for battery longevity and I should set a charge limit. Well then maybe 80% should be the new 100% and the advertised capacity should be the 80%.


This balancing act is already happening. If you modify the battery controller, you can totally continue charging beyond the voltage that the phone considers to be 100%. It also increases the risk of damaging the battery (https://www.acebattery.com/blogs/what-will-happen-when-a-lit...). What they define as 100% is already some point on a damage probability curve, and charging to anything below that point will further decrease the amount of battery stress (for li-ion batteries and similar technologies)

Fwiw, based on tests I've seen recently such as https://www.youtube.com/watch?v=Lj4LMlGr4og, I think limiting to 80% is overblown, but somewhere in the 90%s could be a sweet spot that gives you several hours' longer battery life than with 80% but still has a much reduced chance of significant degradation. I don't understand why they didn't make this configurable


> The trend of buying SBCs for general purpose compute is declining,

Were people actually doing that?


More like people try doing anything other than use the base OS, and realize the bottom-tier x86 mini-PCs are 3-4x faster for the same price, and can encode a basic video stream without bogging down.

If the RPI came with any recent mid-tier Snapdragon SOC, it might be interesting. Or if someone made a Linux distro that supports all devices on one of the Snapdragon X Elite laptops, that would be interesting.

Instead, it's more like the equivalent of a cheap desktop with integrated GPU from 20 years ago, on a single board, with decent linux support, and GPIO. So it's either a linux learning toy, or an integrated component within another product, and not much in between.


Qualcomm has rebranded a Snapdragon with quadruple Cortex-A78 cores (and 4 small Cortex-A55), from the expensive smartphones of 2021, as "Dragonwing" QCM6490 and they now sell it for embedded devices.

There are at least 3 or 4 SBCs with it, in RPI sizes and prices.

Cortex-A78 is much faster than the Cortex-A76 from RK3588 or the latest RPI (e.g. at least 50% faster at the same clock frequency), and its speed at the same clock frequency does not differ much from that of recent medium-size cores like Cortex-A720 or Cortex-A725.

Cortex-A78 is the stage when Arm stopped making significant micro-architectural changes in medium-sized cores. The later improvements were in the bigger Cortex-X cores. The main disadvantage of the older Cortex-A78 is that it does not implement the SVE instruction set of the Armv9-A ISA.

While mini-PCs with Intel/AMD CPUs are usually preferable, for an ARM SBC I would no longer buy any model that has older cores than Cortex-A78.

Besides the Qualcomm Dragonwing based SBCs, there are also Cortex-A78 based SBCs with Mediatek or NVIDIA CPUs, but those are more expensive.

Raspberry Pi are excellent at being general-purpose, full-Linux boxes that consume very low power (some can idle at <1W). Perfect for ambient computing, cron-jobs, MQTT-related hackery, VPN gateways, ad-blocking DNS servers, or anything else that isn't CPU-bound, but benefits from being always available[1].

1. In my case, this ironically includes orchestrating higher-wattage computers via Wake-on-Lan and powering them down when not needed


Bottom tier computers were more than $25.


They still are. They always have been.

Since the introduction of the OG Raspberry Pi, 14 years ago, there's been an ongoing cognitive problem wherein people look at the price of a brand new, never used SBC that can purchased from a reliable retail company.

Then they also look at the price of a used corpo PC (that is bigger, and noisier) that some rando in Iowa is selling on eBay.

And then they boldly compare the prices of the two things as if these details just don't exist.

But the details do exist. The details show that the two things are not the same. They can never be the same.

One is a shiny fresh apple that is free of blemishes, and the other is a bruised old grapefruit that someone has already started eating. They're both fruit, but they're very different things.


It's tiny and low power, I run CI on a Pi5 and do a few other things and experiments on them.


I've used them for mostly dedicated tasks, at least the RPi3 and older. I've used the RPi3 as CUPS servers at a couple of sites, for a few printers. Been running for many years now 24/7 with no issues. As I could buy those SBCs for the original low price and the installation was a total no-brainer, I would never consider using any kind of mini PC for that.

I have a couple of RPi4 with 8GB and 4GB RAM respectively, these I have been using as kind-of general computers (they're running off SSDs instead of SD cards). I've had no reason so far to replace them with anything Intel/AMD. On the other hand they can't replace my laptop computer - though I wish they could, as I use the laptop computer with an external display and external keyboard 100% of the time, so its form factor is just in the way. But there's way too little RAM on the SBCs. It's bad enough on the laptop computer, with its measly 16GB.


I built a nice little cyberdeck around an RPi 5 but it's turned out to be very disappointing. I was counting on classic X11's virtual display stuff to enable a 1080x480 screen to be usable with panning (virtual 720p or something, just a cool vertical pan). Problem is, the X11 support sucks, and so there's almost no 2D acceleration, so this simple thing that used to work great on a 486 with an ATI SVGA doesn't work very well at all on a machine a thousand times faster. Wayland has of course no support for a feature like this one, so I'm stuck with a screen too narrow to use, and performance for everything else that's pretty sub-par.


Aah, I had totally forgotten about that X11 feature, I did use it for something very many years ago. I have only used the default setup (which is presumably Wayland) on the Pi, looks good but I don't actually use display features much.


I haven't tried it myself but niri might do what you want using Wayland https://github.com/niri-wm/niri


Raspberry Pi was and is selling official desktop kits: https://www.raspberrypi.com/products/raspberry-pi-4-desktop-...

I wouldn't wish it upon an enemy, but it's a thing.


I daily drove my Raspberry Pi 5 for all of 2024. It primarily compiled tons of C++ and served 1080p video via Jellyfin, and it did so flawlessly.


They are cheap and seem like the hardware is good enough. The hardware is, but getting software support very diy.


They probably define general purpose as anything homelab based that runs on a commodity OS.


Yeah Raspi even sells a keyboard formfactor and there was a Raspi laptop made from 3D printable casing and basic peripherals (screen, keyboard with mouse nub) for it. A cheap quasi-open source laptop at the time.


People do all manner of wacky stuff with Pis that could be more easily done with traditional machines. Kubernetes clusters and emulation boxes are the more common use cases; the former can be done with VMs on a desktop and the latter is easily accomplished via a used SFF machine off of eBay. I've also heard multiple anecdotes of people building Pi clusters to run agentic development workflows in parallel.

I think in all cases it's the sheer novelty of doing something with a different ISA and form factor. Having built and racked my share of servers I see no reason to build a miniature datacenter in my home but, hey, to each their own.


I concur with this. The novelty of the Pi is getting a computer somewhere that you normally wouldn't due to the size and complexity. GPIO is a very nice addition, but it looks like conventional USB to GPIO is a thing so it's not really a huge driver to use a Pi.


> Is the 1 percenters getting dumber or acting like it?

I feel like their messages are designed to derail people's train of thought.

People start to realize that technology isn't fulfilling and they need to re-access their lives? Nah... introspection is a modern invention and that act of reflection is actually the source of your discontent. Stop thinking about it and just go with the flow, you'll be much happier when you stop concerning yourselves with the state of the environment, other people's well being, if your work is fulfilling, or the fact that you have no retirement.


The rub is that people don't want transmission networks to go away. They just don't want to pay for the maintenance.

In many US municipalities the cost of infrastructure is rolled into the per unit fee meaning high consumers pay more. This works fine until folks adopt solar and their consumption goes negative.

The right answer is a connection fee based on the cost to maintain your hookup to the grid.


As is the case in Australia. We personally pay around AU$2/day grid connect fee


They certainly look viable as replacements for my Tesla P40 for virtual workloads.
