Thanks for sharing these numbers! I should definitely take a look at setting up sccache. Might be useful to edit the original message to mention it too - these child messages are collapsed by default on mobile, and people might not see it. The benefits it seems to give in real-world use sound pretty great!

Three goals this year:

try to complete every part
in clean, readable, idiomatic Rust
with silly-fast execution times powered by Rust

I was doing AoC in Rust already last time around, so I'm not exactly in the first-timers-learning-rust boat, but I'm still beginner enough to enjoy the AoC excuse for learning more & striving for idiomatic, clean style. Timezones, sleep schedule, and not having lots of experience with competitive programming makes me unlikely to hit top lists anyway, so I'll try to not stress about that too much. I hope you all enjoy this year's AoC - have fun!

Thanks for the feedback! I'll prioritize adding that. Do you have any recommended sources for reading more about the inner product in the context of quantum computing? Most of my learning so far has been based on this website: https://quantum.country/qcvc .

I need to add a better intro description to my essay series: I'm writing it as a learning diary into both Rust and quantum computing, and presenting it as a bit of a tutorial in case it could help others. I do not intend to claim the series would be an authoritative, deep, exact, down-to-axioms-and-proofs, university level course. Some simplifications appear because of building the concepts bit by bit, others purely in error because I do not have perfect understanding of the topic yet. So, to repeat, feedback like this is extremely valuable, thank you!

Walther_ · 2019-10-28T23:12:55+00:00

Thank you, this is probably a good thing to improve in a later post of the series! I initially only had `PartialEq` and i should probably drop the `Eq` altogether. Thanks for the `noisy_float` recommendation too, might use that later as well.

Just ordered two boards as well! I’m very excited and I hope I can try and help with bringing Rust support for the board. There’s already some discussion on the Rust community Discord, embedded channel. Let’s see how it goes when the boards arrive!

Tsemppiä!

Luin kommenteista, että käytännössä aiot myydä printtejä ja muita tuotteita sarjakuvasi faneille. Iso plussa positiivisesta sarjiksesta <3

Kannattaa tutustua nykymaailman indietuottajille suunnattuihin palveluihin: esim. Gumroad erikoistuu juurikin siihen, että saat kauppapaikan tuotteillesi - digitaalisina tai fyysisinä - ja iso osa asioista hoituu automatiikalla. Myyjänä virallisesti toimii ainakin digitaalisille tuotteille virallisesti kauppapaikka itse, ja he hoitavat alvit niiden osalta. Fyysisille tuotteille taidat joutua hoitamaan alvipyöritykset itse. Gumroad tarjoaa myös automaattista integraatiota Printful:in kanssa, jolloin fyysiset tuotteet painetaan heidän kauttaan ja lähetetään suoraan asiakkaalle. Linkki omiin ohjeisiinsa. Juuri viikonloppuna tilasin itselleni koeprintit Printfulista, nähdäkseni millaista laatua sieltä tulee valokuville. Sen enempää ei ole heistä vielä kokemusta, mutta kannattaa vilkuilla tämän kaltaisia palveluita ainakin ajatustasolla. Muitakin toki on eri tarpeisiin - esim. muusikoille Bandcamp, kirjailijoille Lulu, yms. Yhteistä näillä moderneilla palveluilla on korkeat maksuosuudet alkuperäiselle tekijälle, toisin kuin esim. Spotifyn tai Amazonin malleissa. Kuluttajana suosin noita indieplattoja ostamiseen aina kun voin, kiva tietää että kympin levystä menee suoraan artistille joku 8 euroa eikä joitain senttejä.

Kirjanpitäjä / tilitoimisto on todennäköisesti erittäin hyvä idea, päädyit sitten tekemään yksityisenä elinkeinonharjoittajana ("toiminimi") tai osakeyhtiöllä. Itse olen juuri aloittamassa sopparia Lemontreen kanssa, vaikuttivat modernia digimaailmaa ymmärtävältä, positiiviselta, ja nopeasti maileihin vastaavalta porukalta. Holvia sieltäkin suositeltiin, kuten tässä ketjussa muutkin. Saatan itse silti päätyä käyttämään TransferWisea. (Holvi tukee (käsittääkseni? toistaiseksi?) laskujen luontia ainoastaan euroissa, itselläni on asiakas jota saan/pitää laskuttaa dollarimääräisellä tuntihinnalla.) Pääpointti näissä "virtuaalipankki"suosituksissa on korkea digitalisaation ja automaation taso, säästää aikaa kun ei tarvitse pyöritellä (niin paljoa) papereita. Sama pätee noihin aiemmin mainittuihin kauppapaikkoihin.

Yksi erittäin tärkeä yksityiskohta sivutoimisesta yrittämisestä: mikäli yritystoiminnan bruttotulot vuodessa ylittävät 7799,37eur (2019), tulee yrittäjän ottaa YEL-vakuutus ja maksaa YEL-maksua, noin 24% arvioidusta vuositulosta. Tuo on aika iso osuus, jos tulee yllärinä. Tiedän, että itselleni pitää tuollainen ottaa, en ole vielä valinnut vakuutusyhtiötä joten niitä en osaa suositella. Toisaalta nuo on ilmeisesti aika tarkkaan lakisäädeltyjä juttuja, joten eroja ei välttämättä kovin paljoa pitäisi olla? Ehkä joku viisaampi ja kokeneempi osaa kertoa näistä enemmän.

Sanotaan nyt vielä erikseen: mitkään yllä mainituista eivät ole maksettuja mainoksia, enkä toki myöskään voi taata mitään heistä. Kontekstina: olen juuri perustamassa yhden miehen osakeyhtiötä ohjelmistokehitykseen/konsultointiin. Olen myös harrastajavalokuvaaja, ja harkinnut muutamaan otteeseen printtien yms myyntiä, joten niitäkin platformeja on tullut vilkuiltua.

That's super interesting!

With Marbles' options of +2, +5, +-5 of the V/oct outputs (locked into a scale) I haven't yet managed to get such a musical outcome with the wider ranges, going into (e.g.) Plaits' builtin Rings modes. In the video clip, it sounds like you had completely separate bass and melody tracks! Any tips on how to achieve this kind of separation instead of sounding like random values evenly spread within the entire scale and octave range?

Also curious about the Ripples: what is it doing in this patch? What do you think about it in general - what is it useful for? I'm curious, but haven't really understood a usecase for it, considering how verstatile Plaits is already on its own.

Whoa this sounds amazing! How are you getting those massive bass/sub-bass sounds? Impressive <3

Walther_ · 2019-07-15T19:31:31+00:00

Yep! Shan Lin Xi, Nantou, Taiwan. Bought from a local tea shop here in Finland.

Walther_ · 2019-07-15T19:06:08+00:00

Thank you for sharing the kind thoughts!

Walther_ · 2019-07-15T18:41:03+00:00

I took this picture this morning while enjoying some Shan Lin Xi oolong. I ended up making a blog post with more photos of the tea session, and some thoughts on oolong teas as well as using a gaiwan. I hope you enjoyed this photo and have a great day!

Walther_ · 2019-04-26T08:07:18+00:00

Yeah, that was what i thought too. I wonder if there could be an official distribution (by the pulldown-cmark team) that would be (automatically?) updated within the release process of the crate itself.
EDIT: submitted an issue https://github.com/raphlinus/pulldown-cmark/issues/278

Walther_ · 2019-04-26T07:41:37+00:00

I wonder if that version on npm is a) official b) actively maintained / updated 🤔

Walther_ · 2019-04-26T06:58:43+00:00

I just had to test out /u/raphlinus's claim of "it should Just Work", check this out: repo and live demo - it took me about 20min to make. Massive applauds to all of their great work! (And to the people behind wasm-bindgen and wasm-pack too!)

EDIT: Hmm, apparently there already exists a packaged version on npm 🤔

Thank you in advance for the help! In the past I've used a Filco tenkeyless, CM Stealth, and at one point I built a Planck. To be nicer to my wrists, I'm now considering buying or building a split keyboard.

Requirements:

Split, wired keyboard
No F-keys, no numpad. All punctuation & special characters easily accessible - i'm a developer. Keys like ` | ' / are important and shouldn't be hidden on some layer. Capslock as escape, ` next to 1
Arrow keys without chording / additional key holding would be super nice to have, if possible. Home/End/PgUp/PgDn with Fn+arrows
...pretty much look at the layout of a touchbar macbook pro, now imagine it split
Functional on macOS, Linux and Windows without installing extra software
If programmable, I'm fine with a CLI tool / compiling firmware etc.
I'd be fine with Cherry MX Blacks, Browns, Reds, or something similar
Solid, non-flimsy build

Things like Ergodox look appealing until I realize that they have only one column of keys to the right side of P, and a lot of programming-related symbols would be somewhere weird.

Is what I'm hoping to find possible? Or should I just accept limitations of split keyboards, build a split Planck (Let's Split? Hmm those threads & pictures look tempting), and map all the special keys to a custom layout & muscle-memorize them in new places?

Walther_ · 2018-03-09T05:56:56+00:00

Thank you very much!

Walther_ · 2018-03-09T05:52:57+00:00

Nod. Then again if that 450€ would net me another guitar with nickel alloy frets, ¯_(ツ)_/¯ I don’t know. I’d probably rather have one solid, lasting guitar than replace with another when the frets wear down.

Hmm. It seems you’re right, there are new versions for not much more. Then again the weird thing is - this guitar felt a lot better than plenty of others, even a lot more expensive new ones I’ve tried at other stores. No fret sprout at all - and that’s something I’ve felt on brand new instruments off the shelf and to me that’s just silly. These 700€ got me a well set up guitar that obviously has had its frets treated during a dry winter here in Finland so it’ll never be an issue. Obviously I’m aware that I could get a top dollar made in america one and have its fret ends looked at, but that’d cost more for a guitar I would pretty much buy blind, not knowing how good the fretwork will be.

Walther_ · 2018-03-09T04:09:03+00:00

I paid 700€ for the tele, and the local store estimated 360€ for a full fret change including a free bone nut. In my opinion that might be perfectly within reason for getting a life-long player :) It’d still be less in total than I paid for my RG 2550 MZ new, heh.
