cameron_b··on Ask HN: I have $5k to spend on a local AI machine, what should I get?
Unpopular but highly promising way to go if training is on your mind- 4x 7900 xtx cards and some nuts and bolts to feed them could be a price per GPU memory high point. There are folks using ROCm with that to put up some interesting numbers in terms of wall clock and power required per training run.
cameron_b··on Take the pedals off the bike
The ins and outs of that coaster brake rule provide a lot of wiggle room. My kids started on balance bikes and have moved up to a 12" and 24" ( wheel size ) from Cleary with hand brakes. They missed the regression of coaster brakes and training wheels. Geometry for kids bikes mainly comes down to the scale of the cranks. Small cranks are needed to lower the foot position and center of gravity enough to be 'in scale' with how we tend to consider bike geometry to work, but the shorter cranks also limit the suitability to a shorter leg length, so my kids' Cleary Gecko is pretty small on my 4yo, but she's ridden it for two years.

Small kids need smaller components, but it's hard to make small components reliable and cost effective. I really appreciate the folks who took the time to translate the same darn brake levers used all over the world to a size suitable for a 2 year old's hand. They're the cutest thing and they're the first thing I had to teach my son how to use after he was cooking it down hills on the balance bike. They get banged up first on a fall, they get merciless treatment, and they perform the same way I expect mine or any other to perform.

cameron_b··on Making AMD GPUs competitive for LLM inference (2023)
I want to double-down on this statement, and call attention to the competitive nature of it. Specifically, I have recently tried to set up Triton on arm hardware. One might presume Nvidia would give attention to an architecture they develop, but the way forward is not easy. For some version of Ubuntu, you might have the correct version of python ( usually older than packaged ) but current LTS is out of luck for guidance or packages.

cameron_b··on Factory Farming Is Better Than Organic Farming
One factor I enjoy exploring is that a key ecological differentiation between Factory Farming and "What everyone enjoys and seems to know might have potential"-Farming is mono-culture vs poly-culture.

In Factory Farming a single variable (crop) is moved to one side of the '=' and the inputs are sorted on the other. The variables of seed rate, fertilizer rate, irrigation rate ( especially against the weather ) and timing ( herbicide before, pesticide after, fertilize at seed time? ) are complex enough, but worthwhile to study in abstraction, such that we have in the 20th century produced such programs at universities and funded them well enough that the USDA keep very good guides for many crops in many soil and climate zone combinations.

Crop rotation and even grazing rotation are even studied quite well for their soil-building (and thereby fertilizer supplanting) potentials. But what I see in practice around me is that the fields here in seven years are planted in cotton seven times. Most farmers would approach rotation with the same sense as if you asked a manufacturing facility to change from plastics manufacturing to use the space for printing and finishing work for textiles in order to improve the skill-set of the operators. Once you ( As a farmer) nail the timing and rates of corn, you don't roll the dice with 10k acres of your livelihood. Once you build the fences for cattle, you don't want to do it all again for sheep ( different line type and height )

The upside is still very attractive. There's just some serious work to do, keeping the lights on.

cameron_b··on Ask HN: What's the state of Common LISPs on ARM64-Linux?
I spent time in gentoo myself, and know what you mean about packages, but the package name in Apt is ‘clisp’ and I double checked by pulling and firing up the repl in Ubuntu 24.04 on a Pi4.
cameron_b··on Ask HN: What's the state of Common LISPs on ARM64-Linux?
clisp is packaged for Ubuntu LTS, I haven't complied anything with it and your make file might need to be checked for compatibility, but it could be an option
cameron_b··on El Capitan: New supercomputer is the fastest
They are in good company, with X, Meta, Microsoft and others not reporting theirs either.

The basis for the ranking was a cumulative tracking of benchmark results that were required as part of commissioning bespoke computers. A contract would be written to buy a computer that could achieve a certain performance in operations per second, and in order to satisfy that the benchmarks were agreed to and codified in the contracts. Government contracts are to a certain extent public information so the goals and clout of successive performance were tracked in this way.

If you don’t need to satisfy a government contract, or don’t need the clout to attract engineers or funding, submitting results draws unwanted attention to what you’re cooking up.

cameron_b··on QNX is now free for anything non-commercial, plus there's an RPi image
One interesting morsel in all of what you described is that for all of the hoop-jumping SpaceX does to bolster rt-Linux, it is -still- easier/faster/ better by some business metric for them than the alternative.

If the redundant hardware and some ground rules they have in place have made the onboarding of developers better and faster, than perhaps it should be recognized that they seem to be prioritizing the DX - especially since plenty of applications in RT will also use redundant hardware and confine their hardware selection similarly to prioritize the performance targets of their application, SpaceX just added developers to the feature matrix.

cameron_b··on Is the Q source the origin of the Gospels?
Q being their lived experience is not out of the question. Finding a written Q would for some detract from the quality of the gospels as a primary source.

Lee Strobel has a good take on the authenticity of the Gospel account in his book The Case For Christ [0] and as always the book is better than the movie

cameron_b··on The Lion of St. Mark's Square in Venice Is Chinese
Don't miss the power play. Giving of a few beautiful birds would be one thing. Now the emperor can create beauty in the realm.

But Lions. Lions are apex predators, and though they hadn't been seen, the trade routes would surely have brought their reputations ahead of them. Lions kill people, they eat camels, they devour. Kill one and you're mighty. Capture one, and you're very powerful, skillful and brave. Double up and you're formidable. Have a breeding pair and you're a warlord with no need for an army.

The Chinese Imperial story has a lot to do with being the presiding authority of knowledge and power. Check out the preoccupation with celestial events. The emperor made sure that he not only knew when and where an eclipse would take place in the realm, but he went there to make sure people knew that the mysteries of the sky were known by the Emperor.

If you want to cozy up to a ruler like that, you show him that you also know similar power, and you have enough to share ~ "tell your people you can make lions now, thanks to your friends in Persia"

Nowadays it just looks more like 5th gen fighter contracts.

cameron_b··on In a rare disclosure, The Pentagon provides an update on the X-37B spaceplane
The Pentagon likely wanted to get ahead of any space observers noticing the heat from aerobraking and disposal of the service module. That might look like a hull loss, and they wouldn't want anyone to report a mission failure.
cameron_b··on Let's talk about animation quality
I love the statement in the conclusion.

Curation is something we intrinsically favor over engagement algorithms. Noisy is easy to quantify, but greatness is not. Greatness might have a lag in engagement metrics while folks read or watch the material. It might provoke consideration, instead of reaction.

Often we need seasons of production in order to calibrate our selection criteria, and hopefully this season of booming generation leads to a very rich new opportunity to curate great things to elevate from the noise.

cameron_b··on Ask HN: Setting up a home office Tips?
Once you have your rough layout, I would give some thought to repetitive stress avoidance. The ergonomics of a home office are slightly different since you aren't stepping away to a meeting in the conference room or walking down to the cafe from time to time. You have to build in your change of scenery, ( schedule your walks, make them happen ) but you also have to give room for just being at your desk more, and making it fit better to how you work.

I also like the "keep it separated" structure for work laptop and personal computer. I have a three-wide monitor setup, and the center is shared. I also use separate keyboard and mice, including a vertical mouse, because I found it helped on the right-hand setup to have a different angle.

I have a sit-stand desk that I find to be really great. You can spend lots for that part, but mine is a manual leg set and a melamine top to go with it from Ikea, along with a stool from Ikea as well to make sure I had a few options but none include 'too slouchy.' You may want a proper chair with a back, but I didn't want to find a place for mine when I wanted to stand and move more. I also find that I keep the desk in a pretty narrow range of height once I find a good spot and I keep it there for days. That's why manual is good for me.

I support collaboration tools, so I am on calls often, and have headsets and cameras sent to me to try out, but I find that I use a few things in rotation. I don't like having things in my ears ( so no airpods for me ) but I do like lightweight over-ear headsets. I'm currently using the Logi Zone Wireless Plus, and I've liked their wired version because it is even lighter (they were both sent to me for evaluation) but I still find myself using speakers for some calls, so I have a soundbar connected to the work dock and a stereo receiver connected to the other. I prefer having separate "out loud" connections, so that I don't have to scramble to set up for a meeting, and the headset floats, since it can handle multiple connections ( dongle, two bluetooth ).

I also have separate cameras, making sure that they have a microphone for when I don't want to wear the headset. Cameras can be a little finicky, most will want supplemental lighting to actually look good. The Poly P5 ($55) does really well in very low light, but I found I didn't like the sound of the audio magic it does ( it has great noise cancellation, but I'd rather use my headset) I find myself using Logi[tech]'s older c525 because the framing fits my desk area with little messing around, and because I have two of them atop the central screen, so the perspective is similar for both computers.

To ease the lighting for the cameras, but keep the lights out of my eyes, I mounted LED strips to the ceiling above me, controlled by WLED and a motion sensor. That ( and the melamine desktop ) provides for a soft "bounce" light to help for calls, without the "ring light" feel of staring at a lamp all day.

That's a bit of a book, but hopefully it helps with the decision process. Your desk is very personal and particular, and it is worth spending the time to evaluate along the way as well.

cameron_b··on We fine-tuned Llama 405B on AMD GPUs
I'm glad to see a full implementation on AMD hardware.

I'm not familiar with JAX, but the idea of providing an abstraction layer to more easily get to work on what hardware is available seems really valuable. Bringing back some competitiveness to the ecosystem will be a big win for workload mobility.

I suspect that price/performance across implementations will be highly dependent on contract details, but do you intend to publish some comparisons in the future?

cameron_b··on iPhone 16 Pro and iPhone 16 Pro Max
I've nursed my wife's SE along until this past week when we bought a used 13 Mini. She has small hands ( not exceptionally small, just small ) and the larger sizes just weren't appealing to her. I've replaced screens, even have a battery for it ready, but the lightning connector finally wearing out and impending End of Support made her upgrade.

cameron_b··on Ask HN: Developer PC setup automations for company owned devices
Setting up the environment for development, especially for onboarding, is a crucial operations step that allows the devs to stand on the shoulders of giants.

If you're asking them to test in prod ( not providing a local test environment for component testing ) or reinvent the wheel ( and get the wheel type right... should I build a bicycle wheel or a railcar wheel? ) then the first week of a new hire is spent trying to align to his or her peers.

cameron_b··on Backdoor in RFID cards allows instant cloning
It is really important when evaluating RFID access control systems to understand that most of the card types are designed to be replicated. Most of the cards printed commercially are "fused" for write-once enumeration, but that pertains to the physical card only. Another card can very easily be written with the same number with the proper hardware, or a different sort of hardware may be made to broadcast the same identifier as the card.

A backdoor is one thing, but the technology is paper-thin when used alone.

RFID is an inexpensive thing-monitoring platform, great for tracking goods in a process (manufacturing or in some cases, warehousing) but it should not be relied upon as the only layer in a security solution.

cameron_b··on The Poor You Will Have with You Always, Even with UBI
Chicken, egg

My father had a community development organization in a blighted part of a southern U.S. city. They bought and restored 14 houses that were falling down and unliveable, and made them available with a very creative financing structure to attempt to alleviate the typically gentrifying investment of renovation. They took on volunteers and lots of other cost-savings for the demolition, but when it came to buying things they had worked out with their bank to finance each house with a construction loan, at a great rate backed by good-credit sponsors co-signing, with a built- in clause to provide for an exit for families who rent to houses to be able to take over the mortgage when they were ready, and it would “wrap” to the renters-to-owners. Their rent would effectively have been paying down the mortgage they would take on.

They found it easy to find candidate houses, easy to find families to rent them, and the families were interested in financial literacy training on offer, but none have yet taken on the mortgage.

When the jobs are terrible, or far away, houses aren’t the silver bullet. Not new houses, not affordable houses, not apartments, not single-family, not any category of housing on its own. More supply would sure be nice, but it isn’t a single line solution.

cameron_b··on Rare footage of largest uncontacted tribe in the world [video]
Mothers are indeed capable of transmitting antibodies through milk, but a significant portion of it does come through exposure and vaccines. As kids start school or daycare they reshuffle all the germs they live with, as they meet new friends, go to camp, start a new school, shuffle again. Often it just feels like a runny nose or a mild fever, a little bit here, a little bit there. The problem is that the body doesn’t not exterminate a virus from its ecology. It may be kept at bay, and from critical mass, but might be extant on the skin ( hands especially ) or in the lungs for instance, just not at infection levels.

Experiencing that petri dish as an adult can be overwhelming. For the same reason that kids have a staggered plan of shots that lasts for a dozen years, you’d have to trickle in the resistance more or less that way that you came about it, or you’re not really “not overloading their immune system”

cameron_b··on Beekeeper furious over destruction of $2M honey crop
Crop Insurance will have requirements for protocols that must be followed to make a crop insurable. For instance, some fruit or seed crops have pollination requirements of 2 hives per acre which must be carried out or they will not provide coverage for certain types of crop failure.

An alternative analog would be not noticing that a cow was acting up, and allowing a whole herd to contract tuberculosis because a farmer didn't contact the vet or isolate parts of his herd from each other or the neighbors. Some things just happen, and they suck. But some things happen when you aren't on top of good management practices, and that sucks but some of it is on the farmer.

cameron_b··on Beekeeper furious over destruction of $2M honey crop
As a few comments have pointed out there seems to be a bit of a disconnect between the article and the state of things on the ground.

For more on AFB, since the article doesn't describe it or the treatment protocols well - https://beeinformed.org/2013/10/21/american-foulbrood-afb/

Apart from rules particular to NZ, because I do not know them, a key factor is that honey and wax containing AFB spores can transmit AFB to other bees in other colonies. The reason this is important is that beekeepers ( speaking as one ) move equipment between hives to balance their growth and give more space to make honey as needed. This is especially true after the honey harvest, when we empty frames of honey and give the wax honey comb back to the bees for them to get ready for the winter.

That makes the timing of this crucial, as it will be less likely for the beekeeper to reduce the damage if the boxes have been removed for harvest, and disassociated from their hive of origin when AFB is discovered. If you can't say where it came from and where it didn't, then it came from everywhere.

It isn't a fun hand to be dealt, and certainly it is worthy of more visibility and research, but it isn't worth wishing he didn't have to destroy it. Even the treatments available need to be used before adding equipment that will be used for honey, because the honey will shield the spores from the treatment and preserve the transmissibility of foul brood.
