scoopertrooper··on QLoRA: Efficient Finetuning of Quantized LLMs
GPT-4 hit it out of the park:

The question seems to be asking about two different types of "pounds": one as a unit of weight (the pound of feathers), and one as a unit of currency (the British pound).

A pound of feathers: This is a measure of weight. In the avoirdupois system (which is commonly used in the US), a pound is defined as exactly 0.45359237 kilograms.

A Great British pound: This is the unit of currency in the United Kingdom, often symbolised as £. The weight of a physical £1 coin, according to the Royal Mint, is 8.75 grams.

So, if we are comparing the weight of these two "pounds," a pound of feathers is heavier than a physical £1 coin.

With an extremely literal reading you are correct, but there was clearly an implication.

scoopertrooper··on Metalens Images the Moon
The article had a discussion about how existing metalenses were limited in size. So, I assume they're saying this metalense is superior to the state of the art in the field of metalenses.
scoopertrooper··on MacBook Pro featuring M2 Pro and M2 Max
The M1 Pro is thought to cost $96. I highly doubt the MacBook Pro will ever approach being a low margin product, even if TSMC triple their prices.

scoopertrooper··on The MTA’s armored money train that ran from 1951 to 2006 in NYC
As a recent arrival to London, the tube is amazing.
scoopertrooper··on The MTA’s armored money train that ran from 1951 to 2006 in NYC
I think this explains why:

> Once the MetroCard vending machines came into the picture, it took a lot longer to collect all the money from a given station than it had from just the token booths, and the money train would sit for long stretches as passenger trains backed up behind it. Also, you can’t do money-collection runs at night if you’re doing track maintenance, and these days the MTA is always doing track maintenance.

scoopertrooper··on New video of Tesla crash demonstrates the problem of semi-automated driving
It looks like the Tesla driver will be at least as fault for the collision with the car behind it. However, it seems the subsequent collisions were caused by fleshy human drivers driving unsafely. I don't know much about traffic law, so I'm unsure how responsibility for the overall pileup will be divided.

From the police report:

> V-1 made an unsafe lane change (21658(a) California Vehicle Code) and was slowing to a stop directly into V-2's path of travel. This caused the front of V-2 to collide into the rear of V-1 (4.0.1. #1). P-2 did not have enough time to perceive and react to V-1's lane change.

V-1 = The Tesla

> P-4 observed V-3 stopping and applied V-4's brakes. V-3 came to a stop to the rear of V-2. P-5 observed V-4 stopping and applied V-5's brakes. As V4 slowed down, P-4 steered V4 towards the #2 lane. Due to P-5's unsafe speed for stopped traffic ahead (22350 California Vehicle Code), P-S failed to safely stop behind V-4 and V-3. The front of V-5 collided into the rear of V-4 (A.O.L #2). V-4 moved into the #2 lane without colliding into any other vehicles. V-5 came to a stop in the #1 lane after colliding into the rear of V-3 (A.O.L #3).

and it goes on from there...

scoopertrooper··on Mazda has tested a synthetic fuel in an unmodified MX5 on a 1000-mile road trip
My comments were limited to the question as to why we might want to do this in preference to EVs. In the case of EVs, the energy source is cheaper, but there is a much higher capital expense as those poor folks who are just scraping by will have to go out and buy new cars.
scoopertrooper··on Mazda has tested a synthetic fuel in an unmodified MX5 on a 1000-mile road trip
Because we could move the entire current stock of cars over to less carbon intensive fuel without having to build an entirely new fleet.

Keeping in mind that manufacturing new cars (and the associated resource extraction) is extremely carbon intensive, then a carbon neutral-ish fuel might actually be the best option overall on a meaningful timescale.

scoopertrooper··on US Department of Energy: Fusion Ignition Achieved
I don’t think MAD is all that effective. At this moment in time we’re seeing:

* Several concurrent arms races in the Middle East, Asia, and Europe

* A high intensity conflict in Ukraine

* China threatening a land invasion into Taiwan

MAD might be preventing a country like Poland from jumping into the Ukraine conflict, but more likely it’s because of its involvement in NATO.

I think collective security organisations are a far more potent force for peace than nuclear weapons. If countries abided by their security agreements in WW2, then we’d have nipped the entire thing in the bud.

scoopertrooper··on iPad Pro M2
Thing that really kills iPad for me is the web browsing experience. I just find iOS Safari so limiting.

It's also needlessly slow (considering M1). I suspect they have some optimisations designed for memory constrained devices like iPhone tuned in the same way for iPad.

Also ad blocker support is limited.

Oh and in a lot of video calling apps, if I try and browse something in Safari while the meeting is happening, then I'll suddenly stop sending video. Though that isn't strictly a Safari issue, more a Apple holding back features from third-party developer issue.

scoopertrooper··on Swiss Post Design System
It's a classic free rider problem. Some jurisdictions will chronically under invest because they can rely on the largesse of others. The incentive for every jurisdiction would be to degenerate into becoming free riders.

This doesn't happen in the corporate world (as much) because of various factors such as tax incentives and market pressures, but would be much more likely in the stately world of government IT.

A better solution would be license the code, such that it could not be used to provide public services unless the governing body contributed to a development association (either in money, code contributions, or some mixture thereof).

Looks like we caught someone's attention:

> I'm temporarily restricting comments to keep comments from turning into +1s while this is trending on Hacker News. If you have additional thoughts that you'd like to share with the Chromium team regarding this issue, please return in a few days to leave a comment (and apologies for the inconvenience).

> As a Chromium contributor that shares information about our progress on extensions issues, I sincerely apologize to extensions developers affected by this issue and the broader community for not sharing an update until now. I'm currently working on a "known issues" document for Manifest V3 that touches on several outstanding issues (including this one), but given the attention on this issue now, I'll quickly share our current thinking on this issue.

> We have always intended to provide support for this functionality in Manifest V3 (for both user-installed and force-installed extensions), and have been iterating on different possible approaches. Our tentative plan (which is not yet finalized) is that the Manifest V3 version of this capability will require extensions to request a new permission scoped to intercepting authentication requests, but will otherwise allow extensions to handle these requests in a similar manner to how they do in Manifest V2.

> The permission string and end user facing warning string have not been finalized yet. Also, we have not yet finalized how this new permission will interact with other permission grants, but extensions that currently have the webRequest permission and broad host permissions will likely not require an additional grant for this permission.

> Finally, I want to note that before we can pursue this capability, we first need to resolve issue 1024211 (now formally marked as a blocker). We are actively working on 1024211 and aim to resolve both that issue and this one before January 2023.

scoopertrooper··on ContainerSSH: Launch containers on demand
For sure, it could be used that way. But, a lot of people were comparing this unfavourably to how they currently manage their dev workflows. My point was that they weren't really the target market.

It seems (from the material on the site) that the motivating use case for this isn't development, but rather running computer labs for students.
scoopertrooper··on Tesla’s Dojo Microarchitecture
I don’t see how they’re going to commercialise this as a cloud compute service.

For one, they’ve built a chip that operates in a fundamentally different way to other chips. So any other company that wanted to use it would have to invest a considerable amount of resources in building up the institutional knowledge to use it effectively.

Additionally, the lack of virtual memory and multi-tasking support renders it pretty much impossible to divide up compute between multiple customers. So, commercialising this would require customers renting out the whole unit, which is contrary to how cloud computing usually works.

Are there companies out there that have the capital and use cases necessary to fit into Dojo Cloud? Maybe, though not one I’ve worked for. Would they trust the stable genius currently heading up Tesla enough to make such an investment? Perhaps, but I wouldn’t, but what do I know?

scoopertrooper··on Blocking Kiwifarms
Yet, people freak out when things like Tornado Cash get sanctioned. If there is total inviolable privacy, then criminals will act with impunity.

But yes, these are indeed complicated problems. All I really know is that I sleep much better at night knowing I've never aided this movement in any way.

scoopertrooper··on Blocking Kiwifarms
The government should have the ability to violate privacy subject to judicial review. Otherwise, no law could be reasonably enforced.

Successive governments have undermined the authority of judicial review and I'd support anyone campaigning to change that. But, the solution isn't to try and build a system that prevents the government from ever piercing the privacy of citizens. That's just a recipe for anarchy.

Honestly, maybe a few years ago I might have been on your side. But, this whole cryptocurrency saga has just soured me on techno-libertarianism. A society needs an effective government (accountable to the people) that can enforce the law.
