Avui és 5è dijous de mes i fem un taller d’expressions regulars! 🤖

Aprendrem a aplicar-les a tasques d’administració amb sed, grep,rename i per la programació en python, javascript, java, …

👾 Són difícils, però els monstres no ens fan por! 🙈

Desxifrem la regex de la vinyeta: ^[\w-.]+@([\w-]+\.)+[\w-]{2,4}$

  • ^ : marca l’inici de línia. Fa que l’expressió que segueix sigui l’inici de línia, que no estigui per allà al mig
  • [\w-.]+:
    • [abc]: representa 1 sol caràcter a triar entre a, b o c.
    • \w: equivalent a a-zA-Z0-9, és a dir, qualsevol lletra majúscula o minúscula, dígit i barra baixa. Les lletres amb accent NO estan incloses
    • -: el caràcter guió -, no té significat especial
    • .: el caràcter punt. Dins dels claudàtors, no té significat especial
    • a+: una o més lletres a. Darrere d’un grup de caràcters, [abc]+ vol dir un o més de qualsevol d’aquests caràcters, en qualsevol ordre i distribució (aaa, ab, ccacbcba)


  • @;: caràcter literal arroba, sense significat especial
  • ([\w-]+\.)+
    • (aaa)+ Una repetició o més del grup dins dels parèntesis
    • [\w-]+: un o més caràcters de lletres maj//min, números, guions alts i baixos
    • \.: un punt, caràcter normal. Li hem de posar \ davant, perquè sinó vol dir “qualsevol caràcter”


  • [\w-]{2,4}: un caràcter alfanumèric, guió baix (inclòs a \w) o alt, i tantes vegades com el rang entre claus: entre 2 i 4: és a dir, 2, 3 o 4 caràcters de tal grup.
  • $ : final de línia. Envoltar l’expressió entre ^ i $ fa que la línia hagi de coincidir de forma completa amb el patró, la regex. No pot representar-ne només un trosset.

Per tant, algunes línies que coincidirien amb aquest patró són:

I una adreça vàlida que no funcionaria, perquè diu que l’última part només pot tenir 4 dígits:

  • admin@mastodon.online (“online” és més llarg que 4 caràcters)

Una adreça invàlida que no coincideix (està ben fet el patró:

  • error@.domini.net Perquè el punt no pot anar just després de l’arroba. Si es pogués, podríem haver simplificat ([\w-]+\.)+ com a [\w-.]+ Fer-ho com està, fa que hi hagi d’haver almenys un caràcter abans d’un posible punt.

Dues adreces més, que farien servir dominis “locals”, de xarxes internes:

  • admin@localhost seria vàlida.
  • admin@lc no ho seria, perquè després de @, ha d’haver-hi 1 o més caràcters + entre 2 i 4 caràcters. És a dir, mínim 3.

Conclusió: tota regex és sempre incompleta. Buscar la regex perfecta ens condemna a escriure la biblia… en arameu i escriptura cuneïforme. Millor buscar regex prou bones per les dades que volem acceptar.

as a visualisation, shouldn't the areas with weaker gravitational pull stick out and those with stronger be sucked in 🤔


Non so perché, ma avrei potuto scommetterci anche le @@ su questo risultato.

La legge, ovviamente, non è uguale per tutti.

I grew up on food stamps and free school lunches. I remember going to food pantries and walking out with peanut butter and shelf-stable cheese in stark white containers with black lettering.

I didn't always like what we had to eat (I hated peanut butter!), but I was lucky enough to never go hungry.

The Trump administration's refusal to pay SNAP benefits is galling to me on a very personal level.

I can't change their minds. I don't have billions of dollars to give to people who need help. But I can do some good. Will you join me in donating to your local food pantry?

If you want to tell me how much you've donated, J and I will contribute that amount to United Food Bank (up to $1000). We're matching $200 in donations so far!

in reply to Aleen

Don't live in the US? Donate to your local food pantry anyway! I'm sure they can use the help no matter where you are.

Everyone deserves to eat.

We sent $50 to our local, the Nazareth Area Food Bank, this morning.


"The founder of a startup business that helps employers and parents with parental leave is asking whether it's fair that parents are taxed as individuals.

Stephanie Pow said she regularly helped parents navigate their entitlements, including Working for Families and Family Boost.

All of these supports are assessed on the basis of household income.

But when it came to tax, that is applied on an individual basis."

Benefits should be individual too.

in reply to Strypey

Either option would be better than the status quo for households like mine with a disabled adult unable to work. Not that NZ classifies ME/CFS as a disability, but that's another story.
in reply to Tim Nicholas

@tim
> Either option would be better than the status quo for households

Cool. So consider the situation of a solo Dad who starts dating someone with a job. WINZ gets wind of this, declares they're now "in a relationship", and means tests his benefit entitlements against her income and assets.

Now he either has to break up with a woman he may have only just started seeing, or depend on her to support him and her kids. She has an equally stark choice.

Individual entitlements are the way.

There's something that didn't really crystallise for me for a long time, which I think I might have learned from Bob Harper implicitly, not sure.

If you like someone's research and want to emulate it, it is more important to read the things that they had *read* than to read the things that they had *written*.

Obviously you should read it all, but I often run into people who are banging their heads against something I wrote when I was just a beginner in a topic trying to understand it myself, and they would be a lot better off reading whatever I had been reading at the time. (A good way to figure out what someone had been reading is to look at the bibliography in their paper or note!)

@graydon @slava Graydon, you're probably the person I know who is best at doing this stuff from outside academia. Researchers have to spend lots of time creating and maintaining this metadata, whether in our heads or actually written down like you describe. The metadata makes it possible to (relatively) quickly understand where new knowledge fits in. But it's also a lot of overhead to maintain. I sometimes envy people who have a lower-overhead way of engaging with papers than I do!

@lindsey @slava The times I've really tried to map an area for my own interest relied very heavily on tools! Google scholar, semantic scholar, etc.

Lately I'm really enjoying inciteful.xyz -- for any given citation graph it also shows a bunch of canned derived queries: prominent authors, journals and institutions, most-cited survey papers that cover the most of the graph, key papers and recent papers, etc. etc.

4 NOVEMBRE 1918: la fine della “grande guerra”… ma non delle guerre

Nel 2018 il collettivo Wu Ming scriveva che le celebrazioni del centenario mostravano che «l'Italia e l’Europa avevano più che mai bisogno di anticorpi antimilitaristi, di diserzione e di rifiuto di ogni intruppamento. Perché quella del “continente sul cui suolo non si sarebbero più combattute guerre” era una fòla…»
