I always find it tricky to understand how tools all relate to each other in an ecosystem and this is a great example of why: the fact that Ansible can do this task, but Teraform would be better suggests that they are tools that have different purposes, but some overlap. What would you say is Ansible’s strong suit?

Thanks for this recommendation. Diverse perspectives are important in underscoring that the Israeli people are not a monolith, and that they are distinct from the state of Israel.

I often see people online speaking about Israelis as though all of them are in favour of the ongoing genocide, when this is simply not the case. That’s not to say that Netanyahu’s control of the media hasn’t led to a depressingly high proportion of Israelis to see themselves as righteous victims — years of state propaganda has unfortunately had an impact. However, there are journalists and activists (Jewish or otherwise) who are working to challenge this rhetoric.

Thanks for the recommendation, I’m always glad to discover new resources. I’m also forever cursing the fact that science degrees don’t put more emphasis on writing and speaking well.

My dude, I’m agreeing with you

Edit: effectively I was saying that I agree with you that there seems to be a particular kind of person who is overly contrarian, very loud and impossible to have productive discussions with.

I felt like the wheelchair example you picked was a great example of how this happens “in the wild”. I wanted to build on your comment by using that example to elaborate on how these contrarian types cause harm, even if they might seem to be concerned and well-intentioned. I found the wheelchair example to be a good one because it is actually something that I’ve seen happen multiple times.

I feel that your reply is an unfair characterisation of my comment. Given how the internet’s communication norms can prime us to read and respond to things in an overly adversarial manner (especially as it’s clear from your original comment that you’ve got way too much experience with silly argumentative types, so I sympathise), I am hoping that your response was based on a misinterpretation of my comment and/or me being insufficiently clear in what I originally wrote (apologies if so).

I do this too much. My defence is that I am a bad writer who’s working to be better.

The wheelchair one (whilst obvious hyperbole) is a great example of why this rhetoric isn’t useful.

Often people who say we should plan walkable cities don’t consider what that would mean for wheelchair users and other disabled people, because they don’t have the lived experience to think along those lines. So it would actually be super useful if someone could say “okay, but what about wheelchair users?” in a constructive way, because there are additional considerations re: pedestrianisation and public transport. Disabled people are way too often treated like an inconvenience or obstacles to progress, and that’s fucking exhausting, so it’s useful to have allies who ask “hey, what about disabled people tho”

The people your comment is about don’t do this. As you highlight, they make things about themselves, and if anything, this makes it harder to have productive conversations about what a ‘walkable city’ for everyone would look like. I suspect that for many of these people, it’s based on a nugget of good intentions inside a blob of insecurity and dread at the state of the world; they feel like they’re not doing enough so they resort to very loudly virtue signalling in the most bizarre ways.

I saw an article recently that looked at the rates of suicide in Israeli soldiers. One guy, who featured heavily in the article, had killed himself after being an IDF bulldozer driver. The article tried to dial up sympathy for him, but additional coverage (in response to this article) highlighted that this guy had posted some pretty horrifying stuff on social media — stuff like videos and photos of him in Gaza, being pretty jovial as he drove through bodies and buildings. I wonder whether the PTSD he experienced afterwards was a sort of moral immune system, and that once he was away from the kind of military camaraderie that normalises atrocities, if he began to reflect on his part in this genocide. At least for him, we’ll never know.

A Jewish, anti-Zionist friend who lived in Israel for a while said that it was disturbing to see how much the Holocaust was leveraged to make people feel scared and insecure. I imagine many members of the IDF do genuinely believe that most, if not all Palestinians hate all Jews and want them to die. That way, they can enthusiastically participate, believing that they are on the side of justice.

I once punched a Nazi at a gig, and I did enjoy it, because it feels good to be righteous and angry. Enough so that it makes me anxious about how easy it would be to lean into anger if it feels righteous.

That sounds somewhat like bread and butter pudding, but I’m not sure

Oh man, this makes me nostalgic. I used to do powerlifting, but I don’t like peanut butter, and I remember cursing that fact

Sometimes I slice some red Leicester cheese on a small plate and microwave it for around 30 seconds, until it melts. Then I eat it with a teaspoon. I first had it when I was desperately hungry but that cheese was literally the only food I had in, and I liked it enough I did it again. (Red Leicester cheese is like cheddar, but it tends to have a distinctly nutty flavour to it).

I used to have chives growing on the windowsill and it always tickled me to sprinkle some chopped chives over the cheese puddle, because a chive garnish feels very fancy but this “meal” was incredibly trashy.

Who is David Kinne and what did he do?

Congrats! I appreciate this post because I want to be where you are in the not too distant future.

Contributing to Open Source can feel overwhelming, especially if working outside of one’s primary field. Personally, I’m a scientist who got interested in open source via my academic interest in open science (such as the FAIR principles for scientific data management and stewardship, which are that data should be Findable, Accessible, Interoperable and Reusable). This got me interested in how scientists share code, which led me to the horrifying realisation that I was a better programmer than many of my peers (and I was mediocre)

Studying open source has been useful for seeing how big projects are managed, and I have been meaning to find a way to contribute (because as you show, programming skills aren’t the only way to do that). It’s cool to see posts like yours because it kicks my ass into gear a little.

A helpful “rule” I set for myself to encourage myself to cook more was to allow myself to indulge if it was a proper, homecooked meal. Stuff like splurging on fancied ingredients (I’m fond of salmon), or having an extra cheesy lasagne. It was a useful carrot to dangle in front of myself, and a useful stepping stone to better habits. I also would sometimes cook for friends, like informal dinner parties (I always found it easier to cook for 4 than for 1)

On the cost side of things, even my fancier meals were still cheaper than takeout. Plus it’s easier to eat healthier if you’re already cooking for yourself often (and I even broke that down into smaller chunks too — I first focussed on adding more veg and general nutrition, then I reduced the proportion of healthy stuff)

This isn’t mine, but a comment from an old university tutors, about a non-teaching administrator.

“She’s an organisational terminator. When she retires, they’ll have to replace her with two people”.

He was wrong — she was replaced by three people. As well as being highly effective at her job, she was really lovely and knew so many students’ names.

This is a great step-by-step. If I were having a root canal, this would make me feel immensely reassured

"Holzinger, 38, is known for freewheeling performances that blur the line between dance theatre and vaudeville. Her all-female cast typically performs partially or fully naked, and previous shows have included live sword-swallowing, tattooing, masturbation and action paintings with blood and fresh excrement.

“Good technique in dance to me is not just someone who can do a perfect tendu, but also someone who can urinate on cue,” Holzinger told the Guardian in an interview earlier this year."

That’s hilarious

I don’t know how gaming on Mac works, but since I switched my home rig to Linux a couple of years ago, I have not once had a problem with installing a new game that doesn’t have native Linux support^[1]. I wonder whether developers have learned that they can rely on Proton for their Linux support (for better or worse).

[1]: there was a point when Baldur’s Gate 3 stopped working after a big update, but I fixed it by switching to Proton-GE, a forked version of Proton. https://github.com/GloriousEggroll/proton-ge-custom

I need to add that to my quotes book, it’s great

Elsewhere in this thread, you mentioned that Immich has great documentation. Are there any other FOSS projects that stand out to you as having great user documentation?

The data are stored, so it’s not a live-feed problem. It is an inordinate amount of data that’s stored though. I don’t actually understand this well enough to explain it well, so I’m going to quote from a book [1]. Apologies for wall of text.

“Serial femtosecond crystallography [(SFX)] experiments produce mountains of data that require [Free Electron Laser (FEL)] facilities to provide many petabytes of storage space and large compute clusters for timely processing of user data. The route to reach the summit of the data mountain requires peak finding, indexing, integration, refinement, and phasing.” […]

"The main reason for [steep increase in data volumes] is simple statistics. Systematic rotation of a single crystal allows all the Bragg peaks, required for structure determination, to be swept through and recorded. Serial collection is a rather inefficient way of measuring all these Bragg peak intensities because each snapshot is from a randomly oriented crystal, and there are no systematic relationships between successive crystal orientations. […]

Consider a game of picking a card from a deck of all 52 cards until all the cards in the deck have been seen. The rotation method could be considered as analogous to picking a card from the top of the deck, looking at it and then throwing it away before picking the next, i.e., sampling without replacement. In this analogy, the faces of the cards represent crystal orientations or Bragg reflections. Only 52 turns are required to see all the cards in this case. Serial collection is akin to randomly picking a card and then putting the card back in the deck before choosing the next card, i.e., sampling with replacement (Fig. 7.1 bottom). How many cards are needed to be drawn before all 52 have been seen? Intuitively, we can see that there is no guarantee that all cards will ever be observed. However, statistically speaking, the expected number of turns to complete the task, c, is given by: where n is the total number of cards. For large n, c converges to n*log(n). That is, for n = 52, it can reasonably be expected that all 52 cards will be observed only after about 236 turns! The problem is further exacerbated because a fraction of the images obtained in an SFX experiment will be blank because the X-ray pulse did not hit a crystal. This fraction varies depending on the sample preparation and delivery methods (see Chaps. 3–5), but is often higher than 60%. The random orientation of crystals and the random picking of this orientation on every measurement represent the primary reasons why SFX data volumes are inherently larger than rotation series data.

The second reason why SFX data volumes are so high is the high variability of many experimental parameters. [There is some randomness in the X-ray pulses themselves]. There may also be a wide variability in the crystals: their size, shape, crystalline order, and even their crystal structure. In effect, each frame in an SFX experiment is from a completely separate experiment to the others."

“The Realities of Experimental Data” "The aim of hit finding in SFX is to determine whether the snapshot contains Bragg spots or not. All the later processing stages are based on Bragg spots, and so frames which do not contain any of them are useless, at least as far as crystallographic data processing is concerned. Conceptually, hit finding seems trivial. However, in practice it can be challenging.

“In an ideal case shown in Fig. 7.5a, the peaks are intense and there is no background noise. In this case, even a simple thresholding algorithm can locate the peaks. Unfortunately, real life is not so simple”

It’s very cool, I wish I knew more about this. A figure I found for approximate data rate is 5GB/s per instrument. I think that’s for the European XFELS.
