Refactoring Blockers

- Lack of patience
- Seeking perfection (can be demotivating)
- Guilt-shame-despair
- I don’t know (we don’t trust our own ability-opinion
- No spears, no spikes
- No compassion

#CQRS is not a general purpose style of architecture.

A thread ⬇️ The first time I built a CQRS system… it was in 2006. The term hadn’t be coined yet by Greg (that happened in 2010), but the practice was ubiquitous in finance with tons of high throughput platforms to build or to maintain.

Him: last time you were saying that you wanted us to avoid using feature branches. Why? 🔽

Me: I was saying that if you want to move toward Continuous Delivery on that specific software, you’d better aim trunk based development. H: ok but what you don’t like with branches?

M: Despite what people here are saying, they are very often long-lived. They last more than a day, more than a couple of days. Sometimes a week… When no merge conflict is detected at the end it’s ok.

Hier a #DevoxxFR , une super session à propos du challenge de releaser sans interruption de service malgré les changements appliqués à nos bases de données relationnelles. Un thread ⬇️ Comment supprimer une colonne, éviter que vos ORMs ne foutent la grouille, éviter les ennuis avec des enums qu’on enrichit… #devoxxFR

La chance d’avoir pu faire 6 editions de #DevoxxFR sur 10. Un thread ⬇️ 2014: mon premier Devoxx avé la moquette 70 (et officiellement ma premiere conf tech en tant que speaker). Avec l’ami Cyrille @_dupdob , on a parlé de programmation reactive, multithreading et de système faible latence.

Interesting techniques applied to wrong usages may hurt. A thread 🔽

Seems obvious in lots of domain but not in our Software development field (note: I didn’t talk about software Engineering on purpose)

Me: Why do we have such an increase of infrastructure costs recently? SRE: It seems that we have a new “OTF env” fad since last month… As a result, more than 70% of our global infrastructure costs are related to non-production environments...

Me: Whaaat? How does this happen? What is “OTF env” exactly?

Design patterns shaped the way we did OOP design. It helped people to share a common language & understanding.

It is not a ‘must-use’ 😀 Initially it helped people to better analyse the context / strengths / limitations / responsibilities of the abstraction that we were coding in OOP.

As a young dev it helped me to be more mature regarding my work and my OO programming.

Sometimes you have to live it to believe it. My 5y son is also the only “black” boy of his class (and almost the only one in this school with his 3,5 years brother)

He has been bullied for 2 years because of his hair...

Last week for the first day at school, we found him like😳 ImageImageImage Even if you don’t call out racism and just talk about bullying, people (parents, some teachers) say that these are just accidents, that we exaggerate...

For the Wachowski sisters, every element you can find in a movie (script, part of directing, music, colors...) is a mean to convey an idea, a worldview.

Thread 🔽 ImageImage They are expecting the audience to challenge their movie, to question it. They also put lots of effort to make thought-provoking entertainment films. ImageImageImageImage

More than 25 years after my last physics course at university, I picked up my old textbook to refresh myself on quantum physics & thermodynamics this WE.

Thread to come about What is Time (episode 2). ImageImage Ok. Since some of you have requested me in PM to continue with the topic of time, I’ll take some time to zoom on the conclusion of ‘the Order of Time’ (Carlo Rovelli’s great book).

In particular the part where he explains that Time doesn’t really exist ;-) ImageImage

“The mystery of Time has always troubled us. It awakens deep emotions which nourish philosophy and religions" (Carlo Rovelli)

What if Time did not exist?

Thread ⬇️ ImageImage 2 visions on ‘What is Time?’ has been opposed for many years: that of Aristotle and that of Newton.

For Aristotle, Time is the measurement of change. Things change continually. We call ‘time’ the measurement, the counting of this change.

If nothing changes, there is no time. Image

@_dupdob_ — La thèse de Kuhn : l’incommensurabilité des paradigmes

Pour T.S. Kuhn, le développement historique de la science s’effectue de manière fondamentalement discontinue.Elle progresse non par accumulation mais par rupture. Il introduit en 1962 le concept de changement de paradigmes Image Un Paradigme définit le genre de problèmes à étudier, les critères à utiliser pour évaluer une solution, mais aussi les procédures expérimentales acceptables (Kuhn explique aussi la dynamique des sciences en tenant compte de facteurs sociaux).

Pour bien comprendre comment le relativisme post-moderne (pour caricaturer: “déconstruisons la vérité; tout est relatif”, “tout n’est que construction sociale”)vient se confronter au matérialisme de certaines sciences,il est utile de faire un petit détour épistémologique

Fil 🔽 Petit rappel déjà : l’épistémologie est la philosophie de la connaissance (quelle est la nature de la connaissance et de l’objectivité ?). En France, on aime bien insister sur le volet « Science » quand on fait de l’épistémologie.

Petit point philo :

Je suis assez fasciné par le nombre de gens dans cette mouvance post-moderne à gauche, à évoquer le paradoxe de l’intolérance de Karl Popper comme justificatif pour ne pas considérer/tolérer leurs opposant(e)s présumé(e)s.

fr.m.wikipedia.org/wiki/Paradoxe_… En gros, j’entends ici ou là des : « celles et ceux qui ne sont pas d’accord avec moi et mon groupe ne sont que des fachos. Donc Popper m’autorise à ce titre à ne pas les tolérer, voire à leur refuser leur existence ou leur humanité (sinon, je serai à terme menacé(e)). » 😳😱
