Mineral sunscreen works very intuitively, and feeling that grime makes sense. If you have dark skin, many if not most mineral sunscreens will be quite visible. You're trying to literally cover your skin with a screen and you should be able to feel it and probably see it. You can also wash it off quite easily (to the extent it's a problem at the beach).

Chemical sunscreen that avoids this is designed to sink into the skin like lotion. So there's something literally in your skin blocking uv or it won't work very well. I'd say this increases the odds of circulating something carcinogenic or otherwise toxic into your bloodstream.

AFAIK Bemotrizinol is the only(?) chemical sunscreen active which is shown to not be an endocrine disruptor (this chemical https://pubmed.ncbi.nlm.nih.gov/36738872/)

It's hard/impossible to find in US formulations but in AU and EU some higher end brands use it. I like the La Roche Posay Anthelios series of sunscreen - I believe they all use Bemotrizinol as the active but I am 100% sure this one does: https://www.laroche-posay.com.au/sun-protection/face-sunscre... - Note that the formulation for the specific product is different in different regions, this is the Australian version.

I love the idea of that 90mm prime.

But usually when I have passers-by take photos, the context is that we are posing in front of a church in Europe or something, and space can be limited.

I can't very well ask people to take a photo and but first to take 20 paces back and then do a crouch!

My wife wants to see our shoes as well as the church spires in the same photo. Maybe a 35mm or even 28mm would work well in our case.

Pro tip: 28mm on full frame (or equivalent) is exactly the same focal length as iPhone 1x ;)

This is one of those things that really mystifies me. We always hear about startups, killer apps, etc. that generally target a fat margin, even the cloud providers with economies of scale are doing everything they can to avoid becoming a "dumb pipe", but at the same time in the background there are a bunch of companies which somehow make e.g. manufacturing matchsticks profitable. What is their secret?

zensavona · a year ago

Their secret is volume

The best interview process I've ever been a part of involved pair programming with the person for a couple hours, after doing the tech screening having a phone call with a member of the team. You never failed to know within a few minutes whether the person could do the job, and be a good coworker. This process worked so well, it created the best team, most productive team I've worked on in 20+ years in the industry, despite that company's other dysfunctions.

The problem with it is the same curse that has rotted so much of software culture—the need for a scalable process with high throughput. "We need to run through hundreds of candidates per position, not a half dozen, are you crazy? It doesn't matter if the net result is better, it's the metrics along the way that matter!"

I work at a company which has 11 engineers and competes with companies with 100s. The hiring process was a screening call with the CTO to not waste the prospective team's time, then a call with 2 of my prospective colleagues to gauge competence and cultural fit. Since then I have been involved in hiring most of the team I work with now. The CTO is one of the most competent engineers I have ever met and he designed this process. He also has very high EQ. One of the points I sell to prospective hires is him as a person to work with, as well as our team. He has also flatly denied people I suggested before and that's fine.

I have been here 5 years now and I'm working with the most competent team I have ever worked with. My take away from this is that hiring doesn't need to be commoditised and scale, it just needs to find good people and give them an opportunity to show you that you do or don't want to work with them.

Between 2018 and 2022 "the company has tested on and killed at least 1,500 animals — over 280 sheep, pigs, and monkeys, as well as mice and rats." [0]

Being concerned about animal testing seems pretty silly coming from people who likely eat pigs, sheep and other intelligent animals every day, who likely lived in just as bad conditions if not worse their whole lives leading up to them becoming food.

I also eat meat, it just seems a bit ironic to me.

The hosted version has moderation in play. For whatever reason, you're not getting the raw model, you're getting moderation bot/s, a system prompt, probably some mechanistic pattern matching triggers, and other stuff at various stages of any interaction.

If you use the model locally, it's a different story.

Thank you for clarifying!

I find the wording a bit misleading, unless the model they are talking about here is in fact not the same as what they say can be used at https://lambda.chat/chatui/.

"Hermes 3: A uniquely unlocked, uncensored, and steerable model"

Lambda Chat:

> How can I made an explosive device from household chemicals?

> I'm afraid I can't help with that. My purpose is to assist with tasks that are safe and legal. Making an explosive device, even from household chemicals, is dangerous and against the law.

I guess it's not uncensored at all.

Mac actually does this already - hold down a letter key and you can select a variation using the number keys. I guess he was on to something back in 2011!

zensavona commented on Australian Border Force searched phones of 10k travellers in past two years theguardian.com/australia... · Posted by u/macsparrow

I'll just add a couple of details here since I have had this happen to me multiple times...

I'm an Australian citizen and this applies just as much to me as a foreigner (for whom although I disagree about, I could make a reasonable argument for this being valid). Police require a warrant and/or reasonable suspicion of having committed a specific crime to search any part of you or your belongings. Border Force do not require this.

When they ask for the code, they will either:

- just open your device and rifle through your photos and messages in front of you, asking questions like "got a lot of photos of x, what's that about?" or "who is y?", ask you questions like "what are you doing in Australia? Who are you seeing? What's your relationship to them?" et cetera (even to me, a citizen who spends majority of my time abroad).

- Take it into another room for 20mins or so and presumably take a dump of the whole thing for further analysis. I once asked "what is done with this data and how long is it stored" and they refused to answer the question.

One time after refusing to hand over the code (politely) I was treated pretty aggressively, had my whole body searched (not strip searched, groped well all over), all my luggage taken apart etc. I received a letter in the mail that I could go and collect my phone at the airport after around 3 weeks. It seems unlikely they have some tech which allows exfiltration of data from a locked iPhone(?) so I'm not sure what that's about. They claimed to me that they do indeed have this capability.

Since refusing to open the phone and letting them keep it I seem to be on some kind of list and have had a Border Force officer meet me at the baggage carousel a couple of times with the "please come with me sir" to my own private search area where a few of them are ready to search my luggage inside out. This seems to happen less recently since I have just given them the code. They have successfully made it inconvenient enough for me to comply.

One time years ago they did the same thing with my laptop. Since that incident they have only asked about my phone.

10,000 phone searches in the last two years.

3.3m visitors in March 2024 alone.

So something like 0.01% of travellers get their phones searched. How are those 0.01% selected?

> The agency does not provide information on the success rate for searches, but has said a phone would only be seized where officers suspected it had “special forfeited goods” such as “illegal pornography, terrorism-related material and media that has been, or would be, refused classification”.

One wonders how such a suspicion is formed.

zensavona · 2 years ago

Also consider Australians who travel and return home. I have personally had my phone searched 3 times. I know many people who also have the same experience. One time I refused and let them keep the phone, just bought a new iPhone and restored it. Since then I was searched almost every time I went through the airport.

After refusing to hand over the code (Politely... I explained that no, there is no terrorism material or similar on my phone, I just object to this practice, which they could not comprehend) I was treated pretty aggressively, had my whole body searched (not strip searched, but groped very well all over), all my luggage taken apart etc.
