roxgib··on Bing ChatGTP demands an apology from user for claiming it's 2023
"We have to be first". That's it. That's the entire business case. They want to be first, and they think that'll turn them into the market leader.
roxgib··on Ask HN: Is “prompt injection” going to be a new common vulnerability?
We used to see those articles, but now that the models are actually good enough to be useful I think people are much more willing to overlook the flaws.
roxgib··on Why does 0.1 and 0.2 = 0.30000000000000004?
Even if you set the data format to 'currency' it still returns false (in Google Sheets). I realise they probably want consistency but it's weird they don't have an option to use a decimal type.
roxgib··on The Dutch benefits scandal: a cautionary tale for algorithmic enforcement
A common theme seems to be humans taking output from an algorithm and blindly making decisions based on it, even when specifically told that the output shouldn't be used as the sole basis for a decision or even as evidence as all, other than cause to apply greater scrutiny. We've seen this in pharmacies flat out refusing to dispense medicine when an automated system flags a concern, even if it's simply supposed to be a prompt to ask more questions, or police trusting the results of facial recognition without further checking they have the right person.

People talk about AI enhancing human abilities, and it can obviously do that, but it's really scary how willing people are to trust a system they've been told shouldn't be trusted.

roxgib··on The fraudulent claims made by IBM about Watson and AI (2021)
When studying data science we had a major assignment that involved stock predictions. I came out on top of the class because I told my model to only bet when it was >90% sure of the outcome, discarding the result otherwise. The rest of the class didn't even think of that, and lost despite many of them have much better models than me when all the results were considered.

They were too focused on the technicalities of the problem too see the big picture, n issue I see a lot in data science students who often struggle to grapple with the problem they're supposed to be solving.

roxgib··on My Controversial Opinion: Ventura Is Apple’s Worst macOS Yet
For scrolling I've always found a trackpad to be equal, if not better, than a touch screen. They feel nicer and are quicker and more accurate. Obviously not as versatile as a touchscreen though. I'd ben fine with it if it didn't otherwise interfere with the desktop experience, but I can't believe that'll be how it plays out.
roxgib··on Beta Testers required for my book-recommendation website
That's actually not too bad, I would have guessed a lot more than that. Good luck!
roxgib··on Weakening TLS protection, South Korean style
Why is it even possible for an application to install root certificates that other applications have to accept? An individual application accepting its own certificates is one thing (as Firefox does), but I can't think of a good reason why apps would need to modify the OS list of certs.
roxgib··on The Coming AI Hackers (2021)
> First, participants interacted with the robot in a normal setting to experience its performance, which was deliberately poor. Then, they had to decide whether or not to follow the robot’s commands in a simulated emergency. In the latter situation, all twenty-six participants obeyed the robot, despite having observed just moments before that the robot had lousy navigational skills. The degree of trust they placed in this machine was striking: when the robot pointed to a dark room with no clear exit, the majority of people obeyed it, rather than safely exiting by the door through which they had entered.

I see this all the time - people putting their faith in systems and rules and computer programs despite knowing that they're more than likely wrong in the given situation. It's bizarre.

I'm interested in how large you think the database might grow? One of the biggest benefits I can see in a site like this is the possibility of discovering 'hidden gems' that aren't well know and thus hard to find, but of course you'll only find what's in the database.

I'm working on different product that involves processing book content, and trying to plan for the computational requirements of millions of books and it's a lot, but I'm guessing running an language model over them would be several magnitudes more demanding.

Good luck, seems like a really promising use of AI!

roxgib··on Meta was scraping sites for years while fighting the practice
Let me get this straight - they paid a company to scrape data for them, and then sued them for scraping their own data as well?
roxgib··on Ask HN: Are ChatGPT answers getting worse for anyone else?
With a paid subscription to OpenAI you can fine-tune their models on additional data, so if you're a business trying to offer an AI based chat help or something this seems achievable.
roxgib··on Ask HN: Are ChatGPT answers getting worse for anyone else?
I assume there's a certain danger in letting it consume data in real time. It wouldn't be hard to trick the web crawler into ingesting undesirable content, and people would quickly start asking it questions like "why is the metro down today?" or "do I need to worry about the hurricane that's forecast for tomorrow?" which it would struggle with. Not to mention how much AI generated data is now found across the internet.
roxgib··on Ask HN: Are ChatGPT answers getting worse for anyone else?
I'm glad they did this, it often produced very wordy answers to straightforward questions, like it was trying to pad out the word count on an essay. In the long run it will be important to get it to better determine how long a response needs to be, but in the meantime you can use the prompt to push it for more information.
roxgib··on Write simply (2021)
Let's not called it complex, or fancy. It's bad writing, so let's just call it that.
roxgib··on What are some interesting uses of WebUSB you have come across?
Thanks, I think I misunderstood the last bit to mean the USB device needed to specifically support WebUSB.
roxgib··on Ask HN: Is it just me or is 5G strictly worse than LTE?
Yes, please share your secrets with us!
roxgib··on Ask HN: Is it just me or is 5G strictly worse than LTE?
Even on 2.4GHz the internet connection is usually the limiting factor anyway, unless you're on a high speed network with a lot of congestion.
roxgib··on Ask HN: Is it just me or is 5G strictly worse than LTE?
I thought that might be the case, but if higher frequency 5G signals are susceptible to small black spots due to buildings etc what's the solution? Presumably they aren't going to deploy enough 'microcells' to cover every place that the cell towers can't reach, so are we stuck with more dead zones if we use 5G?
roxgib··on Ask HN: Is it just me or is 5G strictly worse than LTE?
Yeah I have this issue with WiFi as well, every time I'm leaving my house I pull out my phone as I'm walking down the street to play music but I have to wait for the one bar of WiFi to disconnect
roxgib··on My Controversial Opinion: Ventura Is Apple’s Worst macOS Yet
Every tech journalist moans about Macs lacking touch screens, but I really hope it never happens. Touch interfaces and desktop interfaces are fundamentally different and having both just forces a lot of compromise. But it seems like Apple gets that and is just unifying the experience a bit rather than paving the way for touch screen MacBooks, at least I hope.
roxgib··on Unconditional Love
Agreed, it's well established that deviating for the normal rules of grammar makes writing harder to read. Breaking it in a deliberate fashion can work, but I don't think this is that. A lot of language is technically redundant but we do it because it aids in comprehension and readability.
roxgib··on Unconditional Love
This seems to imply that 'loving' someone means continuing to treat them in a particular way or taking everything they do in stride. A person might love their partner, but still decide that they need to break up with them for one reason or another. You might say that they didn't really love them, but does love have to be overpowering?
roxgib··on Ask HN: Is it just me or is 5G strictly worse than LTE?
It wouldn't be so bad if phones were better at switching to the best available signal, they they could use the efficient 5G connection when it's available, but fall back to 4G when the 5G is blocked by a building or something (which I gather is more common due to the high frequencies used in 5G). But they seem to insist on connecting to a crappy 5G signal even if an excellent 4G signal is available. Same with 3G, which is often fine for many tasks.
roxgib··on Ask HN: Is it just me or is 5G strictly worse than LTE?
I think capacity is a big part of it? People consuming a lot more video at higher resolutions so while 3G might have been fine for the time we needed to upgrade to squeeze more bandwidth into the available spectrum. It wouldn't be so bad if phones were better and switching to the best available signal, they they could use the efficient 5G connection when it's available, but fall back to 4G when the 5G is blocked by a building or something (which I gather is more common due to the high frequencies used)
roxgib··on What are some interesting uses of WebUSB you have come across?
Does a device need to specifically support WebUSB, or will it work with any USB device so long as the web page supports it? Or is it the browser that needs to support the device? I found contradictory information on this when searching.
roxgib··on There’s no such thing as affordable housing
So the tl;dr is that building more housing, of any kind, will alleviate prices at the lower end of the market. I think this makes a lot of sense, though I find it weird that he starts off by saying that new construction doesn't have any impact, and then finishes by saying the opposite. I hear this same thing a lot from economists who say the impact of new construction is too small because it only accounts for <1% of the total housing stock each year at best, but that doesn't make sense to me - what other levers are you going to pull? Immigration?

Anyway, I'm putting all my hopes on remote work.

n=10. n=6 for the control group. I stopped reading at that point.
roxgib··on About Security Keys for Apple ID
> They also support a 28 digit recovery key you can print out and a method for trusted contacts to help recover your account.

Suggesting you shouldn't be required to have multiple keys?

roxgib··on Seven years on, what do we know about the disappearance of flight MH370? (2021)
From the report it was recovered from backup files at the system level, it wasn't as simple as a save game file or whatever. It's possible there's more data there or that what's there has different interpretations - we can only speculate at this point based on the very limited information that's been released.
