robbomacrae··on New GPT-3 model: text-DaVinci-003
I've always been in love with models.

But seriously between this, stable diffusion, and co-pilot.. what a time to be alive! I hope this takes the sting off of all those folks laid off. Just think of all the projects that can be accelerated with these tools. Personally I've got co-pilot helping me build an application using GPT3 summarizations and I'm working on a board game with stable diffusion supplying the artwork. If only Nvidia would hurry up and make an affordable consumer 48gb ram 4090 ti...

robbomacrae··on New GPT-3 model: text-DaVinci-003
I've been trying out various models for summarization and I have to say, on first glance, this davinci-003 doesn't impress compared to davinci-002 or facebook/bart-large-cnn. If you throw in "summarize the following text:" and copy in the contents of https://en.wikipedia.org/wiki/Hacker_News you get the following (temperature 0.0 max tokens 100)[0]:

davinci-003

Hacker News is a social news website focusing on computer science and entrepreneurship, run by Y Combinator. It was created by Paul Graham in 2007 and is moderated by Daniel Gackle. It is intended to recreate a community similar to the early days of Reddit, but with a karma system that requires users to accumulate 501 points before they can downvote content. It also has automated flame and spam detectors and active human moderation, as well as a "voting rings" detector. It

davinci-002

Hacker News is a social news website focusing on computer science and entrepreneurship. It is run by the investment fund and startup incubator Y Combinator. The site was created by Paul Graham in February 2007. Initially called Startup News or occasionally News.YC., it became known by its current name on August 14, 2007.

facebook/bart-large-cnn

Hacker News is a social news website focusing on computer science and entrepreneurship. It is run by the investment fund and startup incubator Y Combinator. In general, content that can be submitted is defined as anything that gratifies one's intellectual curiosity. The site has a proactive attitude in moderating content, including automated flame and spam detectors and active human moderation.

Curious if anyone knows any good alternatives or tricks to improve the summaries? For now I'm using the bart one as it has the advantage of being downloadable from huggingface so you can run it yourself [1].

robbomacrae··on Lab-Grown Meat Is Safe to Eat, FDA Says
I have extended family doing the same in South Brazil. But those cows require a bit of care, a fair chunk of land, and release a large amount of methane. Lab meat will beat it in the end one day when all costs are considered.
robbomacrae··on Lab-Grown Meat Is Safe to Eat, FDA Says
To add to the other points being made... meat is subsidized and doesn't include the cost of the externalities. It's hard to imagine that in the long run, plant based meat or lab grown meat will be more expensive than growing, feeding, and looking after animals.
robbomacrae··on Cooling the Earth with a sunshade near the inner Lagrange point (2006)
I'm no Musk fan but is this true? I thought Starlink was low altitude so everything would fall back down pretty quickly. And while I imagine its not great for astronomy surely it's not much work for some institution or enterprising individual to create a tool for using the known position and timing of such satellites to help remove their impact on images?
robbomacrae··on The FBHHRBNRSSSHK-Algorithm for Multiplication is still not the end
Well there could be an argument that computational saving info should be shared to reduce energy usage but I also think it's fine to sit on it a while.
robbomacrae··on Meta Quest Pro
I didn't skip that. I said "You brought up a good point". I agree it was a good point. But they ruined the argument a bit by being overly dramatic. It would have been better to skip the judgmental snide remark at the end so we could have focussed on the good point.
robbomacrae··on The FBHHRBNRSSSHK-Algorithm for Multiplication is still not the end
My admittedly less charitable take is that they may have been sitting on this 1 operation optimization for a while, noticed it works on the new method, and only decided to go public now they have seen the positive reception and potential of such collaborations.
robbomacrae··on Meta Quest Pro
How can wanting to chill with friends possibly make them a bad friend? You brought up a good point but then kind of ruined it with such a wild accusation.
robbomacrae··on Stable Diffusion based image compression
Yes indeed. I've been looking for an auto summarizer that reliably doesn't change the content. So far everything I've tried will make up or edit a key fact once in a while.
robbomacrae··on Charl-e: “Stable Diffusion on your Mac in 1 click”
Christian Crantell has already made a Stable Diffusion plugin for photoshop[0]. Not 1st party mind, but given Photoshop's transforms already included I imagine they have people looking into it.

robbomacrae··on Korean nuclear fusion reactor achieves 100M°C for 30 seconds
I don't follow. What you said seems to me the definition of the most efficient. Or at least.. it is what I assumed they meant.
robbomacrae··on The optimal amount of fraud is non-zero
I agree whole heartedly. Often wondered the same. But I'd always think a small amount of conflict is needed to keep our defenses evolving in case we ever come into contact with a society that would be more sophisticated than us in that regard. The same applies to computer viruses, pathogens, and even scams and haggling. I know at least some of these been explored already in fiction (Pandora's Star, War of the Worlds, Bender's Big Score).
robbomacrae··on The optimal amount of fraud is non-zero
This whole article is one giant time sapping piece of click bait.

The author makes the unexpected claim that businesses want a non zero amount of fraud. And so as a reader you are tempted to read on because you haven't heard this before. But essentially the argument is that fraud is needed as an unavoidable byproduct of allowing trust/credit in the system to facilitate transactions. However, if businesses could have the trust without the fraud of course they would. I wouldn't be so upset if the author had been more upfront about what this was about. I'm sure there are plenty of people out there who are learning about the fraud and trust/credit relationship for the first time. Just don't try and spin this in a way that it isn't.

robbomacrae··on “It’s time for Apple to fix texting”
And yet I get plenty of spam via text on my iPhone. What is more, I cannot block numbers from texting me (unless there's an option I haven't found). What is more, a clearly spam text will stay as an alert number grabbing at my attention until I open up and see whatever spam image text was sent my way to dismiss it which is surely a security risk.

I used to work at Apple but this messaging stuff is really damning.

robbomacrae··on MyNoise – Background Noise Generators
Thanks Stephane,

We use this app on all of our devices for helping the kids (and ourselves) to sleep. My only concern is that they will grow up dependent on it!

robbomacrae··on Absurd Trolley Problems
I would choose the human in both situations.

Lots of animals die due to our existence and not just for our food. We accidentally kill things all the time with our vehicles and the pollution we cause. I wish it wasn't the case but you can't step outside without ruining some ants day.

To then be faced with a choice between killing one more animal or a human... my heart would bleed for the monkey but to do anything else would be murder and pretty hypocritical unless one lives an extremely vegan and eco friendly lifestyle.

No medical issue will strip away the fact that it is a human life. I'll make it more absurd for you... they could have a terminal disease and likely be dead tomorrow and I'd still choose to sacrifice the monkey to give them 24 more hours.

robbomacrae··on Absurd Trolley Problems
Chickens are sentient. Would you have changed your answer if it were chickens?

I chose to save the human as the prompt didn't set a bar for the level of sentience. Also partly because of shameless speciesism. I love animals, have gone mostly vegetarian, but I would still save a human over any other animal.

robbomacrae··on FCC commissioner wants TikTok removed from app stores over spying concerns
This seems very much like a tangential side rant but I one hundred percent agree with you. I was even thinking of writing an extension to block any links and mentions of the royal family. I'm British and I can't stand the amount of media coverage they get.
robbomacrae··on MIT researchers propose Brazil-sized fleet of “space bubbles” to cool the Earth
I don't see anywhere in the article what they would do about micrometeoroids?

At what rate would they expect bubbles to get punctured? Would those punctures result in movements as the trapped gas escapes?

The JSTW at L2 has already been hit by 4 as of June 11th [0]. Are we expecting fewer at L1?

robbomacrae··on What happened to the lab-leak hypothesis?
I think this is correct. I also think the point being made is that we SHOULD spend more time learning lessons and applying them to try and prevent some of the future pandemics. Imagine if we can prevent just one out of the next 10 pandemics through investment here. That would be millions of lives saved!

Part of the problem with the covid pandemic is how much we let our guard down. For example, the Global Health Security and Biodefense unit — responsible for pandemic preparedness — was established in 2015 by Barack Obama’s National Security Advisor, Susan Rice [0].

This was then disbanded under Trump and its head Timothy Ziemer, top White House official in the NSC for leading U.S. response against a pandemic, left the administration [1].

Jon Oliver has a good segment on why we need to focus on preventing future pandemics [2].

robbomacrae··on The Floppotron 3.0
Yes I suppose sonic pi could be used to map logs to an audio stream. I might have to tinker with this. Thanks!
robbomacrae··on The Floppotron 3.0
Looks pretty cool. Thanks!
robbomacrae··on The Floppotron 3.0
A little. Isn't the point of the demo to be the visual? Which to be fair, is like how the original post purpose is the music itself. But I was thinking something that happened as a happy accidental extra result of whatever you're doing with auto generated visual representations of how your code fits together like some Escher contraption.

15.ai has it
robbomacrae··on The Floppotron 3.0
I've often wished there was a way programming could produce art as a by product. That way we could see something more tangible for our efforts, have a landmark system for help recalling it all, and show progress to our non technical family members.

This has made me think that making music as a by product would also be pretty neat.. being able to hear different sounds for different functions would be a much more intuitive way of inspecting the overall health and performance of your system than trudging through logs.

If anyone knows of anything like this I would be happy to pay for it!

robbomacrae··on LaMDA is not sentient
I share your concerns. Imagine what effect a sympathetic AI would have on 4chan incels. We've already seen Twitter bots manipulated to repeat alt-right rhetoric [0]. An adversary could find building such bots a cheap and a very hard to trace way of causing damage.

[0]: https://en.wikipedia.org/wiki/Tay_(bot)

robbomacrae··on LaMDA is not sentient
Yes there are sadly many ways to profit from a bot that can better emulate a human so I guess my call to action was unrealistic in that regard.

Can we do anything to better prepare users for this kind of attack? Better bot detection? Or are we doomed to a dystopian future where any interaction not in person is suspect and then, once the androids arrive, even those will be also.

robbomacrae··on LaMDA is not sentient
Perhaps. Maybe our brains are just an algorithm and data, maybe (for all I know) you are a bot, maybe we are all a simulation.

I think these sort of arguments (assuming you meant the first - that brains are just maths) that equate our thinking with a neural network are hard to deny but also we have thousands of years of history that have established that suffering is real and conscious, whilst debatably imaginary, is at least a consideration.

I therefore argue we must, for example, maintain a massive distinction between the morals of turning off a human brain vs turning off a neural network.

The calculations and output of the neural network could be achieved with pen and paper (albeit it might take years). I doubt a human brains workings could ever be calculated that way.

robbomacrae··on LaMDA is not sentient
"was surely not the intent of the Turing test"

I agree but it is what it is. I think the Turing test has a few shortcomings in that regard. For one, I think it overestimated the awareness of the average evaluator by not stipulating any requirements for that role.

I was just asking if we should drop that test as some sort of academic goal being aimed for by the likes of Google but perhaps that's not the point.. as others have mentioned, it will be profitable to fool evaluators so the incentive is there regardless.
