Unfortunately it seems it's largely been replaced by (equally?) toxic BPS https://www.fidra.org.uk/bisphenols/bps-joins-eu-candidate-l...


Thanks for sharing, interesting read.

> In January 2020, BPA was restricted from use in thermal paper, including tickets and receipts, across the EU (3). As a result, another bisphenol, Bisphenol-S (BPS), began to take its place. In fact, an ECHA survey estimated that 61% of all thermal paper would contain BPS as a substitute for BPA, despite concerns of BPS being equally as harmful (6). Fast forward three years and BPS is now recognised as “toxic to reproduction” and a hormone disruptor, and has been added to the EU’s candidate list for Substance of Very High Concern (SVHCs), a common first step on the road to restriction (7).


The mentioned company above (Exacompta) also make some without BPS (they say "sans phenol"). No idea what they use instead, for all I know it could be worse ^^ but I think the made in France is encouraging, we tend to have safer norms than EU which itself tends to have safer norms than the world.


This thermal paper from Germany which another commenter mentioned upthread

https://www.oekobon.de/

claims "no BPA/BPS" and "phenol-free". (Hopefully that doesn't turn out to mean that they found something even worse to make it out of!)


do you know why merchants prefer to sell or why customers preferred to buy BPA/BPS instead of paper drenched in ascorbic acid (vitamin C)?

It even seems easy to make you own DIY version: squeeze some lemons, unroll, drench, dry and reroll a properly sized roll of normal paper in it.


The blue one has neither


Wow, this is super cool. The whole experience of interacting/watching/listening to it is very relaxing and harmonious-feeling. Thanks for sharing! :)


Such a nice surprisingly thorough overview (nice diagrams too!)


If I understand the law correctly, you can only send your kid to English-speaking public school if you yourself went to an English-speaking school in Canada.


Yes. There is also some complicated points system so that if one parent did goes for just a few years it’s not enough to get that right.


That's crazy


They are quite different neural net architectures! CNNs (ie convolutional neural nets) have little "patches" that are used to pick up features of the input such as edges, etc. As you go deeper in the network, these patches tend to pick up more and more abstract features, like textures or kinds of object. All this is passed into a fully connected network which then gives a prediction. CNNs are most famously used for image classification.

In contrast, an LLM is usually built using a sequence of Transformer modules, which use something called "self-attention": it modifies each piece of input seen so far to include information about its relationship with the other bits of input. In text, this is a natural thing to do (what role does my word play in the sentence); you can also do it with images (giving you Vision Transformers, aka ViTs) but it might be less natural. After self-attention is a little fully connected network, and then the output is passed into a new transformer, etc, for a number of times (commonly 6), until the output of the final transformer is used as the prediction.

In a nutshell: very different architectures, exploiting different aspects of the data (CNN: local structure; Transformer: relationship between all elements in the context).


I think this could be very useful! But I guess there are still some hallucinations to deal with: I uploaded an arxiv paper and asked who the authors were, and it it hallucinated 4/4 (and stopped working when I asked it to please use the paper as a reference to answer my question).


Back in 2015 when I still thought I'd be a physicist, I was a summer intern at Fermilab on the MicroBooNE experiment. The sense of excitement and teamwork on the 10th floor was something I dearly missed when I went to CERN the year after.

Every day at 3pm was "coffee and cookies", and my colleagues and I would join the line filled with physicists of all ages and from across the lab, to grab a cookie or maybe two. On Fridays the coffee turned into wine and the cookies into cheese.

The second floor, where the coffee was, had a rotating art installation, which at some point included an acrylic box filled with water. One day this box went from being empty to containing a live goldfish.

I hope Fermilab retains this sense of magic that I have found in so few other places.


When I last worked in person in IT, a few members of my team would get up at 2pm to get coffee and chat about work and life. Different people went in the mornings. It was really useful to team-build and feel decent about work.

People who say "I don't have friends at work" with pride are completely foreign to me. I don't understand how people are supposed to have any joy at work, or get over comms barriers, when there is no opportunity to get to know coworkers as people.


I can have lunch and water cooler chat friends at work, but rarely do they turn into invite over to bbq on the weekend friends. There's a big difference.

You can be friendly, but when something happens at work and one of you no longer works there...things get weird. Those weekend bbqs that you had with work friends no longer happen, or they keep going for a bit, but conversations are awkward since the still employed are no longer free to discuss or the no-longer employed harbors resentment that isn't exactly hidden. What kind of "friend" was that after all?


It all depends. Most of my coworkers are friendly, some are friends. We respect each other, etc, but it most cases any contacts end when someone leaves the company. The key marker is can I discuss any matters, including inappropriate, politically incorrect? In most cases not. But with true friend we can discuss anything without a fear of being reported. And we are still in contact many year after.


This and other kinds of social issues are why some cultures put a very clear line between professional and personal. God forbid if it concerns intimate matters, which are the worst.


Isn't this just another downside to stacked ranking? Plenty of other professions allow you to make friends.


I've lost too many friends to mass-layoffs over the years. I just can't do that shit anymore.


Just responding to some of your points - sorry if this comes off as abrasive.

> a few members of my team would get up at 2pm to get coffee and chat about work and life

If I stopped programming arbitrarily at 2:00pm when my hours are 9:00am-5:00pm I expect to be let go (unless I'm taking this as my lunch period). Especially to socialize over coffee. As a production-level IC I just can't do that ethically, and perhaps this is a personal fault... but I'm paid to keep my nose down and develop software solutions, not to socialize with colleagues. If we need to meet over work it's best to get that on the calendar so there's some expectation of formality - not in some adhoc social hour/afternoon.

> People who say "I don't have friends at work" with pride are completely foreign to me.

I don't say it with "pride," but I have 100% learned to put distance between my personal and professional lives. Example: every time I have had to deal with suicide scares it's always been a professional relationship/colleague of sorts. It's been three times now, and for some reason I seem like a trustable enough person that people put this on me. I hate it.

Then, there's people who I have thought were close friends who completely ghosted me after moving to a different company - who knows, maybe it's me. But I've heard lots of people express similar frustrations and it's just pushed me to consider every work friendship a "work friendship." I have more equitable and consistent relationships when I make friends outside of my profession, I invest my time and energy there.

Finally there's the emotional investment. When it comes to employment I am not part of a "family," and I'd really appreciate that sort of language to stop. Right now. I am selling my time and labor to a business to solve problems and fulfill operational duties that they require of me. At any point, employer or employee can terminate that relationship because "at will." This is surely not a "family," and I personally believe it is not an ideal spot to sink your social energy. I've seen people have their careers pulled from underneath them after over-investing socially into the company - they do not do well. I'm not here to emotionally invest during my 9-5, I'm here for business. Unless it's a requirement of the job (sales, vendors, talent aq, etc.) I am not putting myself out there socially/emotionally.

Sorry to share some anecdotes but I think there are very valid reasons to put distance between your work relationships and your personal ones, purposefully erecting a buffer. I think it's very valid if someone wants to keep their work relationships just that: work relationships.

Just an aside, but at a senior level walking around and bullshitting with people is where a lot of the work gets done. At some point you'll get involved with a project that's so interesting you'll never really stop thinking about it, and then your idea of what someone looks like when they're "working" will change.


Also at formal senior/project lead/management levels myself. I do not find what you are positing to be my reality, at all.

I don't think bullshitting leads to high productivity or task throughput. Anecdotally, I find the bullshitters are the ones holding the 20-40% of productive IC's back because of constant distractions, spec/scope socializing (and subsequent creep), and just general talking while others are trying to work. If there needs to be a meeting to work out spec I'd rather it be on the calendar where it's company sanctioned, has an agenda, and where we can formally gather action items to be delegated and assigned -- that last list of things does not happen with "bullshitting."

> At some point you'll get involved with a project that's so interesting you'll never really stop thinking about it, and then your idea of what someone looks like when they're "working" will change.

I've been very involved and interested in my work and this has not happened to me yet. People socializing in adhoc 1:1 conversations is where the "good ol' boys" comes from, and it has typically been incredibly damaging to my clients, specs, and timelines. My idea of people working is people traditionally working, adhering to the SDLC, and ensuring technical communications are not private.

In my anecdotal experience, "bullshitting" is a negative thing. I'd rather not be a "bullshitter," and I hope those around me don't use such language to describe me -- especially at a professional level.

Just to reiterate:

"Bullshitting" != "where a lot of the work gets done." "Bullshitting" is a negative thing.

And, being incredibly invested into a project has not yet changed my opinion on this. I find this comment makes assumptions of future me with the "at some point" language. Using a hypothetical regarding someone else's future self isn't ideal when arguing a point. It feels condescending in a "you just don't know yet" sorta way.


This isn't someone coming up to your desk, this is more like two people from different departments rubber ducking each other on the walk to get coffee. It's all pre-spec work as you'd put it, but a bit of a continual review as well. 'Shop talk' doesn't really cover the scope.

> I find this comment makes assumptions of future me with the "at some point" language. Using a hypothetical regarding someone else's future self isn't ideal when arguing a point. It feels condescending in a "you just don't know yet" sorta way.

Yeah I'm working on a certain tone in my writing and haven't quite nailed shifts in PoV e.g. transitioning from you/you to you/one in a single sentence. Appreciate the feedback.


To your first point, the coffee stops improved my ability to work with my teammates and get projects done. We were better for it. And for a fair amount of that time, we were salaried so we were paid to get a job done, not by how long it took.

I see a lot of the points though.


Perks of a stand-alone national lab I guess! My workplace (Savannah River Site) has a strict no-booze policy. Although people frequently bring donuts!


That's awesome! I work over at ESnet (located w/ LBNL) and got to interact with some folks over at SRS. Y'all are cool bunch :)


Ha, based on this comment you could be one of my classmates! Did you do undergrad in TN?


Yea well cern had beer on tap ... For lunch!


It still does!

Source: Currently at CERN.


Tell me, is it still in a goofy wooden barrel?


"beer"...

/ducks


Ok now I’m curious what beer is served at CERN. I am not familiar with any Swiss beer and only a handful of unspectacular French beers.


If my memory does not fail me, that would be Feldschlösschen: https://feldschloesschen.ch/

(2003-2007 period)


I don’t know about the beer at CERN specifically but the beer culture of Geneva generally is subpar.


Local Calvinus Blanche and Calvinus Ambrée are pretty good for Swiss standards. And the country is starting to produce great biers, e.g. JA-MoM: https://www.brauerei-oerlikon.ch/shop/JA-MoM-p285045816



I don't think it was particularly good or bad, when I was there. I don't drink beer none of my friends ever said "this beer is great" or "this beer sucks".


Free beer. Free beer. That’s my favorite brand. If I didn’t have to buy it it’s the best beer in the land. —The Yoopers


So happy to see this! Shattered PD is by far the best mobile game I've ever played; hopefully this means many more can experience it. Note that it's free on Android - highly recommend!
