<p>173.245.58.0 is owned by cloudflare (<a href="https://www.cloudflare.com/ips/" rel="nofollow">https://www.cloudflare.com/ips/</a>). You're probably tracking the IP address of cloudflare's reverse proxy that hits your application instead of true source IP (which cloudflare will copy into X-Forwarded-For header).<p>Likely you pulled this IP from your application's logs? If you're trying to track bot traffic, use Cloudflare's built-in analytics tool.<p>Also a single source IP can be hosted in geographically distinct locations - that's called anycasting, which cloudflare does use, however I don't think that's the issue here.</p>

<p>This will very likely be an app inside "Toybox" - where there are other fun/goofy/pointless apps like replacing the car's horn with goat bleating / fart noises, light show, romance mode, changing the car's path to rainbow etc.<p>If that's the case, this may actually be fun. The only notification a user may get would be in release notes when updates happens. It may not be an ad in the way most users understand what an ad is, as in, its not going to play when you turn on the car. That said, Tesla is probably getting paid for this.</p>

<p>1. Don’t work from home. Even if you are working for a fully remote company, get a personal office.<p>2. Have a laptop or desktop that only has a command line on it. Don’t carry your normal laptop along.<p>3. Don’t carry your phone. Instead invest in an Apple Watch with cellular or something similar for emergency calling. Have a regular old landline for your office.<p>4. Invest in specialized devices such as kindles and zoom meeting devices.<p>1-2 months of this will help change your default behavior of needing to satisfy your frequent dopamine demands immediately. Slowly introduce other devices.</p>

<p>3DS is not just 2FA, but it has an option to shift liability to the card issuer in case of card-stolen disputes. Our fraud has come to near 0 once we started 3DS enforcement. 1% of 3DS transactions don't lead to a liability shift, and in such cases, we flag those transactions and call the customer to get more forms of identification that they own the card.<p>With PayPal - beyond ownership of email address (which is already compromised), there's nothing else to validate against.</p>

<p>They are probably testing stolen/hacked PayPal accounts. Probably doing a dispute to ensure the owners don’t suspect anything is going wrong, until they use it for bigger transactions. Unfortunately with PayPal there’s no way to ascertain ownership of an account (like 3DS).<p>This used to happen to us, eventually after haggling with PayPay support for over a year on who should bear the cost, we just shut down PayPal payments. Don’t have anything better to offer, sorry.</p>

<p>We have to use some criteria when all applicants are effectively the same - 4000 applicants and 6 interviewers. We interview each applicant at least 3 times.<p>Definition of being smart is to be quick at mental math and logic, but the puzzles are represented visually. And yes, both those skills are needed in the course of our work.<p>Contrary to what you might expect, over 80% take the test. I suppose during next hiring season, we could A/B against random selection to compare what % go past our interview.</p>

<p>We get a few thousand fresh grads applying to us each year. It’s practically impossible to interview every one of them. At the same time, any sort of coding assignment we give is easily defeated by AI—so that’s not useful either and there are very few signals there.<p>What we do instead is send out a test - something like a mental ability test - with hundreds of somewhat randomized questions. Many of these are highly visual in nature, making them hard to copy-paste into an AI for quick answers. The idea is that smarter candidates will solve these questions in just a few seconds - faster than it would take to ask an AI. They do the test for 30 minutes.<p>It’s not expected that anyone finishes the test. The goal is to generate a distribution of performance, and we simply start interviewing from the top end and make offers every week until we hit our hiring quota. Of course, this means we likely miss out on some great candidates unfortunately.<p>We bring the selected candidates into our office for a full day of interviews, where we explicitly monitor for any AI usage. The process generally appears to work.<p>On a different note, things are just getting weird.</p>

<p>Hiring devs is perfectly fine if you don't look for F# skills - just hire generally smart people, and allow them 1-2 weeks to get comfortable with F#. Make them just solve problems from project euler or something.<p>For those who have already done functional programming, they wont take more than 2 days to start getting productive. For those who have written a lot of code, it will take them ~2 weeks to pick up functional thinking.<p>Anyone who is still uncomfortable with F# after 1 month - well that's a strong signal that the dev isn't a fast learner.<p>Additionally, I've never had anyone reject our job offer because we do F#. I'm sure a whole bunch of people might only be looking for python or javascript jobs, but that's fine because I'm not looking for them. I always have more people who I want to hire but I can't due to budget constraints.<p>Source: direct experience - I run a pure F# company with a team size of ~80.</p>

<p>F# is quite usable with AI. All AI models are perfectly capable of generating idiomatic F# code. In fact, because it has a nice type system, if you ask the AI to model the problem well with types before implementing, hallucinated bugs are also easier caught.</p>

<p>Everything is an expression (i.e. its an actual functional programming language), and along with it comes a different way of thinking about problems. Coupled with a really good type system which has discriminated unions, you'll have much fewer bugs.<p>Pro tip: don't write F# like you would write C# - then you might as well write C#. Take the time to learn the functional primitives.</p>

<p>Cellular smartwatches allow you to leave your phone behind, and still be "somewhat" connected - e.g. allowing people to reach you during emergencies, calling a taxi, checking maps etc. It can unlock my front door, be used for pay for a coffee or food, and can control all the lights in my home and allow me to answer my doorbell with a view of who is ringing it. Now it also has a digital drivers license and a mobile key to my car, so I can walk out just with my watch and nothing else, and that feels liberating.<p>The fitness stuff is a plus - its better than nothing, and answers simple questions like how long I've hiked or walked.<p>Battery life is an issue yes, but that's simple - pay more and get the $800 version ;)</p>

<p>I used to get frequent migraine attacks - there were times when I would be down 3 days in a week, just unable to be productive. A lot of it was induced by stress.<p>I then tried something novel - I took some LSD. I had an intense psychedelic trip, dug deep into my psyche, realized I was a giant ball of anxiety. The anxiety's root cause was ultimately a fear of mortality (around the same time, my dad was going through a terminal illness, we spent many years in and out of ICUs, so a lot of that had soaked into me). I had to come to terms with my own mortality, which happened when I just "melted" away and lost sense of self momentarily, and once I did, I felt so much lighter as I came out of the trip.<p>My migraines stopped right then and there; I kid you not. I didn't get a single headache for the next 4-5 years, and in general, I was also a lot more balanced and at peace, even though I went through some highly stressful times. It was miraculous.<p>Of course, life has a way of creeping up on me, and I do get migraines occasionally, but when I do, I know how to stop them - I just need to slow down, meditate (not feel-good meditations all these meditation apps promote, but actually meditate and <i>feel</i> your muscles relaxing). That single LSD trip taught me how to relax myself physiologically.<p>Not saying this is going to work for everyone, just sharing my personal experience. Please keep in mind that playing with psychedelics is like playing with fire. Exercise caution.</p>

<p>So much negativity all the time. The fact remains that AI models are out in the public domain. If you’re unable to see how that can improve the lives of an average person, that’s a failure of imagination.<p>Don’t let megacorps dominance prevent individual action. The best way to be hopeful is to effect change in your immediate surroundings. Teach people how to leverage AI, then they won’t be hold hostage to the tyranny of the beauraucrats - doctors, lawyers, accountants, politicians, software engineers, project managers, bankers, investment advisors etc.<p>Yes, AI makes mistakes .. so what? Humans do too.<p>Credit where credit is due - Sam may be no saint, but OpenAI deserves credit for launching this revolution. Directly or indirectly that led to the release of open models. Would the results have been the same without Sam? Nobody knows, not a point worth anybody’s time debating.<p>Given most of us here are software engineers, it’s natural to feel threatened, there will be those of us whose skills will be made obsolete. And some of us will make the jump to the land of ideas, and these tools will empower us to build solutions that previously required large companies to build. Perhaps that might mean that we focus less on monetary rewards instead of change, as it becomes ever so easy to effect that change.<p>To those whose skills will be made obsolete - you have a choice on whether you want to let that happen. Some amount of fear is healthy - keeps our mind alert and allows us to grow.<p>There will be a growing pain, as our species evolves. We’ll have to navigate that with empathy.<p>Change starts from you. You are more powerful than you can imagine, at any given point.</p>
