I didn't know about using alignment to avoid cache bouncing. Fascinating stuff
bitexploder · 6 days ago
Yep. Super important in lock free synchronization primitives like ring buffers. Cache line padded atomics are really cool :)

Unifi is the Apple of networking gear. When something new is released the HN crowd is excited even when the same functionality existed already with another company.

I still like them. I have almost no real complaints about their products. They just work for me. Here is an example: I had a Netgate with pfsense for my home gateway. My primary home internet provider can be a little flaky, so I have a beefy 5G gateway backup. It was way too hard to configure one of the ports to support automatic WAN failover. The, less expensive, unifi product just worked. It was just a simple setting in the gateway's management UI. The information provided in the dashboard is rich and it implements things like constant QoS monitoring that has a nice plot. It adopts and manages my home wifi and makes it super easy to configure channels, analyze congestion, and do all the deeper technical configuration I could ask for.

Another example, I had Frigate set up on a home rolled NAS. Again, it worked alright, but it always stole time from me. It always needed a little maintenance or tweaking or thinking. I bought a UNVR and modern Unifi cameras. Adopted, zero thinking or management from me. I still retain control of my data and it respects my privacy. It isn't perfect, but at the price point it solved meaningful problems I cared about in both cases. Yes they are commercial products and not open source, but they are priced reasonably to my eyes (the UCG ultra was actually cheaper than the netgate). That makes me a happy customer.

I have run their wifi APs for over a decade with no problems. It's not perfect, I know there are still privacy concerns. No company is really perfect, but they are good to me.

From the article:

""It's my view that there's no way you're going to get a return on that, because $8 trillion of capex means you need roughly $800 billion of profit just to pay for the interest," he said."

Right, THEY can't, but cloud providers potentially can. And there are probably other uses for everything not GPU/TPU for the Google's of the world. They are out way less than IBM which cannot monetize the space or build data centers efficiently like AWS and Google.

Come on, it's not that hard to think of a solution.

Pass a law making it illegal to do a combination of collecting and storing personally identifying information, such as a license plate number, in a timestamped database with location data. Extra penalty if it's done for the purpose of selling the data.

bitexploder · 23 days ago
Thing is, I am not /really/ worried about private citizens with access to this. There are just limits to what a private citizen or even massive corporation can do. What concerns me is when governments get involved and aggregate these private databases. The government is the one that can violate your 4A rights. It exists to protect us FROM the government. Not from private citizens and that exposure is very different. A private citizen can't for example, prosecute me, etc.

I'm curious what you think the solution is?

Taking a photograph of a car with its license plate is legal. As is selling a photo you've taken, whether it has a license plate or not.

Therefore taking millions of photos in public of cars, and turning their license plate numbers into a database is legal, as is selling that information. It's all data gained in public.

Obviously it's now scary that you're being tracked. But what is the solution? We certainly don't want to outlaw taking photos in public. Is it the mass aggregation of already-public data that should be made illegal? What adverse consequences might that have, e.g. journalists compiling public data to prove governmental corruption?

Doing this as a private citizen is one thing. When the government does it the implications are vastly different. That is kind of the whole point of the constitution.

California did not require numbered paper plates when Jobs did this. Car dealers would put paper plates advertising themselves on the car, but you could remove them. Your temporary registration was taped on the inside of the front windshield.

I personally saw his SL500 with dealer plates a couple of times while visiting the Apple campus as a vendor. He'd park in the handicap spot too.

bitexploder · 23 days ago
Yep, and just paid all the fines if / when he got them.

License plates aren't compatible with the 4th amendment, and this only becomes more obvious with time.
bitexploder · 23 days ago
People may not understand how deep this goes. With municipalities eagerly allowing companies like Flock to hoover up license plates and centrally aggregate this data there is a very strong argument this is true and amounts to 4A violations when considered in total.

Add that many states have laws that are /more/ punishing if you intentionally obscure your plate than simply not having one, what other conclusion can be drawn? The state’s arguments are thin. “Oh we need it to find criminals / vehicles of interest” oh sure, so you get to suck up all our data to protect a few toll roads and track a few supposed criminals. The balance of benefit to society is dubious at best IMO.

bitexploder commented on Manganese is Lyme disease's double-edge sword   news.northwestern.edu/sto... · Posted by u/gmays

The problem with antibiotics at least in some countries is that official guidelines take the position that chronic Lyme does not exist, and thus doctors are forbidden to write long-term prescription to antibiotics for Lyme. Short-term may not work, as research suggests that antibiotics works only on some phases of the life-cycle of borreliosis and only for some co-infections.
bitexploder · 25 days ago
Chronic Lyme where the bacteria persists does not exist. There is no evidence the primary bacterial infection persists as far as I have been able to discover. So, that is a faulty starting point in terms of your framing. Now, what is chronic lyme, does the bacteria injure the nervous system, does it leave "debris" behind that maybe antibiotics somehow help the immune system attack and clear? That is way less clear and not validated medical science.

I thought this kind of chaining was already part of these systems.
bitexploder · 25 days ago
It can be, but the more specific context you can give the better, especially on your initial prompting. If it is opaque to you who knows what it is doing. Dialing in the initial spec/prompt for 5 minutes is still important. Different LLMs and models will do better or worse on this and by being a human in the loop on this initial stuff my experience is much higher quality, which indicates to me, the LLM tries, but just doesn't always have enough info to implement your intentions in many cases yet.

I like to ask "Make a pacman game in a single html page". No model has ever gotten a decent game in one shot. My attempt with Gemini3 was no better than 2.5.
bitexploder · 25 days ago
Something else to consider. I often have much better success with something like: Create a prompt that creates a specification for a pacman game in a single html page. Consider edge cases and key implementation details that result in bugs. <take prompt>, execute prompt. It will often yield a much better result than one generic prompt. Now that models are trained on how to generate prompts for themselves this is quite productive. You can also ask it to implement everything in stages and implement tests, and even evaluate its tests! I know that isn't quite the same as "Implement pacman on an HTML page" but still, with very minimal human effort you can get the intended result.
