Aqui está um guia de perguntas frequentes que gostaria de ter tido antes do casamento. Como começar o processo? Dá para fazer online e funciona bem! Depois do pagamento eventualmente ligaram-me para confirmar o horário da cerimónia. Depois de confirmado recebes um email de confirmação. Um email! Isso quer dizer que se eu responder ao email com outras perguntas, eles vão responder? Infelizmente, não.https://llcampos.com/posts/biostasis/Wed, 12 Jan 2022 17:22:30 +0000https://llcampos.com/posts/biostasis/Nota 1: Este post assume que já sabes o que é a criónica (traduzido do inglês cryonics)/biostasis - se não sabes mas estás interessado, sugiro este vídeo de 15 mins (inglês) ou este post (inglês). Nota 2: Vou usar a expressão biostasis no artigo em vez de criónica, porque criónica é uma palavra muito feia. Desde há pouco tempo, residentes europeus não tinham grandes opções em relação a biostasis - as escolhas eram uma das organizações norte-americanos, Alcor e CI, ou a russa KrioRus.https://llcampos.com/posts/evolution-of-professions-portuguese-parliament/Sat, 17 Jul 2021 11:58:04 +0100https://llcampos.com/posts/evolution-of-professions-portuguese-parliament/(English translation below) Recentemente tive uma conversa com a minha namorada sobre o futuro da representação de certas profissões no parlamento Português. Mas é difícil discutir este assunto se não soubermos sequer qual é o estado actual da distribuição e como é que esta evoluiu ao longo dos anos. Pois bem, para obter esta informação, usei os dados abertos do site oficial do parlamento Português e algumas programming skills. (Código está disponível aqui) Aqui vai o que obtive:https://llcampos.com/posts/dog-toothbrushing/Tue, 29 Jun 2021 17:22:31 +0100https://llcampos.com/posts/dog-toothbrushing/Recently I learned that dogs also need to have their teeth brushed, to avoid some nasty health issues. Here’s my current understanding on why dog oral hygienic practices are valuable. 1 - The main goal of tooth-brushing in dogs is to avoid periodontitis, a severe gum infection that can lead to tooth loss and other serious health complications, including (…) histologic changes in renal glomeruli and interstitium, heart and blood vessel lesions, hepatic inflammation, respiratory tract bacteria, low birth weight offspring, and early death (From Prevention of Periodontal Disease)https://llcampos.com/posts/film-franchises-and-meaning/Sat, 29 May 2021 08:42:08 +0100https://llcampos.com/posts/film-franchises-and-meaning/In A Nihilist’s Guide to Meaning Kevin Simler explains the idea that meaningful things are things that point to other things: A thing X will be perceived as meaningful in context C to the extent that it’s connected to other meaningful things in C. Recently this idea gave me a greater appreciation of film franchises and how they are a great source of meaning, regardless of the intrinsic quality of each film individually.https://llcampos.com/posts/what-should-we-feed-our-pets/Tue, 25 May 2021 23:02:54 +0100https://llcampos.com/posts/what-should-we-feed-our-pets/Review of Chapters 1, 2 and 5 of Dr. Pitcairn’s Complete Guide to Natural Health for Dogs & Catshttps://llcampos.com/posts/simulacao-recibos-verdes-vs-unipessoal/Mon, 18 Jan 2021 17:01:22 +0000https://llcampos.com/posts/simulacao-recibos-verdes-vs-unipessoal/(Non-Portuguese readers: this is boring finance stuff that only applies if you live in Portugal.

Another reaction I had after researching interpretations of I’m Thinking of Ending Things (ITOET) was felling bad I didn’t come up with any of them. Which is not surprising - I have a lot of trouble interpreting complex works of art, being it paintings, books or movies. For example, I don’t understand poetry at all. If someone starts reciting poetry to me I’m completely unable to follow, although I listen to podcasts/audiobooks at 1.https://llcampos.com/posts/hidden-meanings-in-art/Sat, 05 Dec 2020 17:54:24 +0000https://llcampos.com/posts/hidden-meanings-in-art/I recently watched the movie I’m Thinking of Ending Things (ITOEF) - I understood none of it. I mean, it was beautiful, but I was unable to come up with any plausible interpretation of what was happening and I found the ones I read on the internet really non-obvious. This annoyed me: what’s the point of hiding the meaning so deep? If the director really wants to make an important point just make it more obvious!https://llcampos.com/posts/how-to-listen-to-your-body/Tue, 01 Dec 2020 17:33:21 +0000https://llcampos.com/posts/how-to-listen-to-your-body/It’s the middle of the afternoon and you just came back home after a run. You feel a little hungry. Do you? Maybe it is just gluttony and you really want that banana with peanut butter, although you don’t actually need it. Actually, you feel a little weak and maybe the urge to eat it’s your body telling you you need some sugar. But maybe you are self-sabotaging your low-calories goals with this rationalization?https://llcampos.com/posts/on-voting/Sat, 28 Nov 2020 18:14:27 +0000https://llcampos.com/posts/on-voting/Portuguese presidential elections are going to happen soon and this lead me to reflect (again) on the value of voting and of being engaged with national politics. I have an aversion of having to keep up with what’s new on national news in general and national politics in particular - things move so fast that keeping up with it would be too stressful. But with the presidential elections coming in, I felt motivated to be an exemplar citizen and do a thorough research about all the candidates so that I could make an informed decision on who to vote for.https://llcampos.com/posts/pordata-alojamentos-e-condicoes-de-vidas/Sat, 07 Nov 2020 15:53:28 +0000https://llcampos.com/posts/pordata-alojamentos-e-condicoes-de-vidas/(Este texto faz parte da minha exploração da PORDATA – uma base de dados relacionados com Portugal) Não tinha ideia de que a construção de casas diminuiu tanto desde 2002. Nesse ano foram construídas aproximadamente 9 vezes mais casas do que em 2019. Adoro este gráfico: A percentagem de agregados com uma arca congeladora subiu ~10% entre 2000 e 2005… e desceu outra vez ~10% até 2010.

Checkout that 2003’s number. An astonishing 82.6% of the population was going to libraries! This sounds too much to me. I don’t think I know anyone who goes to libraries. But I guess that 2020 is a really different world than 2003.https://llcampos.com/posts/pordata-hours-of-work-per-week/Sun, 18 Oct 2020 10:04:33 +0000https://llcampos.com/posts/pordata-hours-of-work-per-week/(This is part of my explorations of PORDATA - A Portuguese open data database) This surprised me: It shows the average of weekly work hours for people who work for some employer (vs. being self-employed). Since the last methodology change (that’s what those dark symbols represent) in 2011 the average diminished by 0.9 hours. There was a decrease in all jobs categories. This happens for both genders: (Dark orange are males, light orange are females)https://llcampos.com/posts/pordata-marriages-per-year/Sat, 17 Oct 2020 18:51:05 +0000https://llcampos.com/posts/pordata-marriages-per-year/(This is part of my explorations of PORDATA - A Portuguese open data database) Here is the plot of total number of marriages per year. Interesting things: Number of marriages per year decreased from ~70.000 in 1960 to ~33.000 in 2019, even though population has increased. Number of marriages per year increased by 20.000 (!) from 1974 to 1975. This is probably somehow related with the fall of the Portuguese dictatorship in 1974 that lead to the immigration of more than 300.https://llcampos.com/posts/scala-using-circe-and-newtype-to-decode-json-with-a-field-with-variable-type/Sun, 06 Sep 2020 17:54:29 +0000https://llcampos.com/posts/scala-using-circe-and-newtype-to-decode-json-with-a-field-with-variable-type/Here’s one way you can quickly decode a JSON using circe: import io.circe._ import io.circe.generic.semiauto.deriveDecoder import io.circe.literal._ case class Example(id: String, field1: String) object Example { implicit val circeDecoder: Decoder\[Example\] = deriveDecoder\[Example\] } val exampleJsonIdAsString: Json = json"""{ "id": "12345", "field1": "something" }""" val example = exampleJsonIdAsString.as\[Example\] println(example) This prints Right(Example(12345,something)). This all works well if the types of the JSON fields are predictable. But what if you’re consuming some API that you don’t control and the same field sometimes comes with different types?https://llcampos.com/posts/til-circe-json-decoding-for-sealed-trait-hierarchies/Tue, 11 Aug 2020 16:10:41 +0000https://llcampos.com/posts/til-circe-json-decoding-for-sealed-trait-hierarchies/import io.circe.generic.auto._ import io.circe.parser.decode sealed trait Thing1 case class SubThing1(a: Int) extends Thing1 decode[Thing1]("""{"SubThing1": {"a": 1}}""") // Returns Right(SubThing1(1)) decode[SubThing1]("""{"a": 1}""") // Returns Right(SubThing1(1))https://llcampos.com/posts/irs-e-etfmatic/Wed, 08 Apr 2020 16:56:57 +0000https://llcampos.com/posts/irs-e-etfmatic/Update 2023: A OneFinance torna desnecessário a maior parte da versão antiga do artigo.

This page will record some of the results. I will not describe the nootropics in question since that information can be found in many places online. Caffeine L-theanine I was excited about this one.

Does this happens in the Portuguese Local Elections for câmara municipal? Let’s take a look. Unfortunately, I can only find computer-readable data on ballot order for the 2013 elections. There is a PDF with this information for 2005, but my efforts to automatically extract data from the document were in vain (I tried some Python PDF extraction tools).https://llcampos.com/posts/portuguese-local-elections-municipalities-with-more-enrolled-voters-have-a-higher-percentage-of-abstention/Wed, 12 Apr 2017 11:25:02 +0000https://llcampos.com/posts/portuguese-local-elections-municipalities-with-more-enrolled-voters-have-a-higher-percentage-of-abstention/2021 EDIT: Originally there were images in this post, but they were lost to the ravages of time. Currently I’m getting into Data Science and as way to practice I’m exploring data on previous Portuguese Local Elections. One interesting thing that I found is that municipalities with a higher number of voters enrolled also have a higher percentage of people not voting. There seems to be some kind of inverse exponential relationship.https://llcampos.com/about/Mon, 01 Jan 0001 00:00:00 +0000https://llcampos.com/about/Indoor enthusiast.
