Clojurians Log v2

Right! 😱 I mean: Right! Insert-cool-guy-emoji-here

I also got that when I tried the link yesterday and also started to worry. Weird message. The doors are not open yet would have made more sense. 😃

Indeed! Maybe it is an implementation detail - that they do not have a separate feature to detect if the doors are not open yet 🤔

Works great in the new Edge browser too (based on Chromium), even on Mac 🙂

Oh, that’s a nice surprise to learn!

So far Firefox seems good for me 🙂

In other gather.town events with many pnrticipants i got stutter audio with Firefox/Linux. Others had the same. Switching to Chrome solved the issue. The codec used for audio seems to be better supported in Chrome. But YMMV…

Right. I'll go with chrome then! I already switched out of Linux because my webcam can't quite be detected - but that's been a common issue on a lot of browser apps requiring video

gather.town is still the best of all the bad options to do an online conference, IMHO.

Not impressed so far since I can’t even sign in 😞

same here

gather.town says my email is not on the guest list, though it is exactly the same email the order confirmation was sent to

@martinklepsch @wichtrup can you help?

I pinged @ramart and he updated my email address to something Google Login recognized.

Likewise!

<mailto:carnun@commsor.com|carnun@commsor.com>

<mailto:dieter@nextjournal.com|dieter@nextjournal.com>

Hey @ramart, still no joy. :((

works now for me, thank you

Already did that.

hmm.. seems to work for me

Yeah… No it stopped. I changed nothing. 😄

Aaand it's back

This uncut version is also still available for the impatient.

good man!

please add your questions here 🙂

Is the Calva debugger based on the CIDER debugger?

How does calva determine whether it should move pairs (map, binding list) on single values up and down inside a form? Is there a way to add new forms that should work on a pair-basis?

thanks for the questions!

I have put the SFX volume all the way down

Oh, for me the chat notifications started again, too

I am trying "respawn"

same here, trying respawn

didn't help

@borkdude: I've now muted the tab itself, in firefox, which has finally made it stop

but doesn't this mute the video as well?

it does

@borkdude: yup, but I'm watching the video on Youtube (in a separate tab)

ok

I only get that sound when i am in another tab. If i am in the gather.town tab, it's quiet.

@borkdude hilarious over the top german language skills 😂

Yes, they will. Especially "later". :)

Please add your questions for the Q&A after the talk here.

How do you choose between graalvm+sci and babashka?

Copy from Gather: tell us about the SCI magic... what is happening there?

It could be stressful with the reputation you've gained in the Clojure community - "the batman of the clojure community" etc.. How do you make it stay "for fun", as opposed to letting it transform into a "chore"?

sorry I didn’t get to all the questions!

🙂

I would still be in a hammock at this point. He’s already up to compiling to native

@viesti thanks :)

@contact238 thanks! :)

no worries, love using all of your amazing tools 🙂

me too, thanks for the nice work and really like that you have found a way to work on these things 🙂

Please add your questions for Philippa’s talk here 🙂

Maybe I just missed it: How are the commands shown in the bottom bar are chosen if there are more than can be displayed?

Have they seen a difference in usage of features when implementing this?

What are the challenges of designing / programming in a Context and Command style? For example, how are contexts registered and then how are commands displayed based on contexts?

Also, where can we play around with lisp machines to know what they used to be like?

Re: “usage of features” and measurement: how do you do A/B testing on context relevance? i.e., how do you measure what aspects of the context are more important to users?

Thanks! 🙏

we have a lot of ideas on how to evolve this towards building more complex UI flows with it

i’m @unkai on twitter, feel free to DM me and we can talk about it more!

@philippmarkovics I’m curious about how you evaluate changes to the context-based information you push to users. How do you manage A/B testing, given that interactions are already so context-sensitive?

(and if not A/B testing, how do you figure out what context is the most appropriate?)

tbh, at this point we made decisions based on feedback we got and based on our own usage

we don’t have a strategy to a/b test this but there are a bunch of key metrics that we look at that sometimes also reveal problems

e.g. number of code cells run, etc

so evaluation will be a bit of everything: looking at some of those metrics, listening to user feedback, etc

Thanks. Very pragmatic. (this stuff is hard)

Please add your questions here...

Where did he learn to tell a story in this fantastic way? 😃 It’s wonderful to listen.

from @filipematossilva: does datahike+firebase support multiple concurrent writers?

2- what’s the largest db you’ve managed to store using this setup?

3- what’s the throughput like?

I'm not familiar with Firebase, but can you push down queries to Firebase, or does the client need to read data out, deserialise, then do queries in memory, in the data model that Datahike uses?

Please add your questions here 🙂

1. What interests me is how she did it with the taxes ? (So the income tax she has to pay when she works. don't you have to pay taxes in the countries where you work?) 2. Or how much did this whole trip cost?

What was the best meal you had?

Since she went to escape home loneliness. Did she meet a lot of people on her trips?

What was the kind of work you did on the trip? How did client deadlines and communication work?

How did you deal with the constantly changing time difference vs your usual work timezone?

From Josh in Gather: For health insurance, can you just add "travel health insurance" to the statutory plans, like TK or AOK?

What did you take away for your life from this trip? Was it worth it, or would you do it differently next time?

Could you imagine doing this again once more but for even longer?

I am still concerned about abroad mobile internet (not SMS or calls). Any insights on that?

From Leah on Gather: q: you said you returned early because of covid, which places did you want to visit but couldnt?

Thank you for the many useful answers. Although 20000€ I find actually quite little. Would have expected more now.

My company is 100% remote and some of our staff have moved around the world — and we often don’t even notice until they tell us 🙂

Please your questions here…

Would it be possible to integrate Clerk into a ClojureScript app? Thinking of rendering components and playing with them in a Storybook style environment @mkvlr

(I guess one of the challenges is accessing functions from a regular CLJS build via Clerk/sci)

What about error handling? Syntax error, exceptions and the like...

From @miro in the chat: Can you run this with Spark as you would Jupyter/Clojupter?

However, not sure how to take a shower during the conf 🤔

Take your phone into the shower (but don’t forget to turn of your camera lol)

I'm now cooking dinner 😂

@h0bbit enjoy your dinner 🙂

On the second screen i solved a Java/JPA/equals/hashcode problem that immediately made me remember my Clojure love and its sanity regarding equality relations…

This is a big one for sure

Sure, i am still looking forward to the real physical thing again.

Yeah!

Just the right place for your questions 🙂

What happens if several predicate functions return true?

Would you say that passing re-frame events around would be an implementation of this system?

https://github.com/worldsingles/commons/blob/master/src/ws/clojure/extensions.clj#L102-L122

Your place for questions 🙂

Tim at Gather: So, cider for .net confirmed?

Do you think using windows drove you towards working on a different set of problems than you would have chosen otherwise?

Bozhidar on Gather: > Is your wife known as Lady Bug? Going forward - she will be! :D

When you get a well designed PR that adds a lot of value. It can be hard to start with No. How do you handle that?

Have you considered full rewrite as v2 or new plugin as a way to chop off extra complexity?

More seriously, where is CLR support for nrepl/cider at these days?

I really want to try and stay for the last ones but, same, we have a little one to feed and put to bed

One has to be honest with themselves if they want to make progress and move forward.

Thanks for joining!

Please add your questions here 🙂

@quoll curious if the choice of using a protocol for implementing a queue (as opposed to a set of functions, for instance) for API aesthetics, performance, pedagogy, or some other reason?

In the asami example: What are the ticks (') at the end of the properties for? Does it mean "update" instead of "insert"?

Question to Paula: How does Asami primarily differ from Crux? (from Henrik)

from Hernik MohrQuestion to Paula: How does Asami primarily differ from Crux?

Thanks for the answer Paula! 👍🏽 Pretty cool work, will look a bit more at Asami.

Thank you 🙂

I’m finding a few instances of reflection in the durable storage code, so I’m working on those

indeed

Yes, exactly here.

From Gavin: is there a lein -> deps translation guide to boostrap old lein dogs like myself

1. Difference to boot 2. How hard was it to develop: What was "the beast of an obstacle"?

How does tool installation work? Does it update ~/.clojure/deps.edn?

When will it be available?

Any thoughts on caching with tools.build (e.g. make), or is that a user space concern?

From Jordan: how are you hoping this impacts the dialy workflow of the normal working clojure dev? *daily

@dominicm caching what exactly?

like intermediate files?

@alexmiller Yeah, intermediate files. make only rebuilds what has changed.

yeah, we haven't done anything explicitly with that, but there are a lot of options with how you structure your build

for example, if you compile, and you have the previously compiled classes on your classpath, you can get partial builds like that. we may decide to do more in this area

Yeah, I almost said AOT, then remembered you've already been working on that. I suppose this work ties in quite nicely with AOT'ing your libraries for faster dev startup.

that's really to some degree an orthogonal concern, but there is definitely overlap in mechanism (can use tools.build to do the compile etc)

might be worth updating that startup time guide once it's out

I was also thinking about the :prep-lib work. A "universal" prep lib of some kind to perform AOT for libraries and cache the AOT across projects, etc.

so we have spent a lot of time thinking about that. it's tricky :)

will it be possible to do overrides of deps for prep-lib stuff?

so this is hard for all the same reasons its always hard - if you're compiling a library, what version of Clojure compiler are you using? Java version? dependency versions? if you're doing this one place and caching it, it's probably wrong for some of the consumers of the library in some of the projects and then you're really building a different environment then you are declaring in the final application(s)

it's the same problem with aot'ing library jars, just not in jars

@hiredman you're running an alias the project declares as how to prep - that alias can do whatever for deps

I am just thinking, if everything is using tools.build to compile things and whatever, and @dominicm had a great scheme for caching things, it seems like it would be a shame if he couldn't make transient dependencies (with a prep-lib) also do the caching (maybe by forcing them to use a custom version of tools.build)

you can still use the approach laid out in https://clojure.org/guides/dev_startup_time

and that's contextual to a project so there are no issues with conflicting versions

not saying this is the final answer here, but everything being added is compatible with the already available approach

we've looked at ways to integrate automated caching into Clojure CLI and even into the compiler itself. we've not yet found something that we liked enough to move forward on

Alex, are your slides available anywhere? I'd love to go through them once more

Thanks Sandra for everything. Liked your dress!

hihi Thank you! Really Second - hand.

Don’t be too modest… I really liked it too 🙂
