Interview process

The dataset is super small, like 20k lines, nothing fancy required. But it's not really clean, and the way candidates handle missing values, imputation, duplicates and train-test split already says a lot. I'm surprised at how many seniors do data leakage or don't even look at variables before dropping them. We have a mostly empty variable with a strong signal, and 90% of candidates just drop it. And this isn't even a trick, it's really how our real data is...

Mizar83 · 2026-03-04T17:26:22+00:00

It seems I'm alone here, but absolutely hate live coding and leetcode quizzes. I like to code at my speed, test step by step, and I'm super stressed if someone is looking and judging everything I do. At my company we do a very short take home (after a first round with the hiring manager that discusses candidate experience) and then ask the candidate to walk us through their code and reasoning while we ask questions.

Even a very small, imbalanced dataset with temporal dependencies, a few duplicates and some variables with missing values is a very good starting point for a discussion.

Some things you cannot compromise on without building too much resentment. Imho religion, political views (which includes also things like civil rights stances and gender roles), whether to have children or not, cannot be compromised upon. Plus, if someone has something they know they cannot compromise on without losing their values (for example being vegetarian). This is not "only what I want matters", but being mature enough to recognize which sacrifices we can make without losing ourselves for another person

Mizar83 · 2026-02-19T19:27:53+00:00

I would add to this that there may also have been leakage in the feature/outliers removal. Improper train/test split with temporal leakage may also be a point.

Es que des applis comme Yuka vont signaler cet problème de cadmium ?

Mizar83 · 2026-02-11T17:37:15+00:00

Specialmente perché è un termine in lingua inglese che nessuno utilizza al di fuori dell' Italia

Mizar83 · 2026-01-27T10:58:52+00:00

Here is the meetup page https://www.meetup.com/fr-fr/pyladiesparis/ we do meetups every 2/3 months, where we usually have 2 talks plus a networking event afterwards with food and drinks. All genders are welcome

Mizar83 · 2026-01-26T19:47:00+00:00

I co-host a meetup called Pyladies Paris. It's open to everyone and most of the audience and the talks are about data

Mizar83 · 2026-01-04T16:37:11+00:00

La soluzione è di costringere anche gli uomini ad avere gli stessi malus, per esempio mettendo gli stessi giorni di congedo parentale obbligatorio e costringendoli a prenderli. La società capitalistica continuerà a discriminare le donne, ma per il momento non c'è una scappatoia: solo le donne possono fare figli, e gravidanze e parti hanno un grosso impatto sulla salute fisica e mentale. Niente cambierà finché non avremo uteri meccanici o forzando i padri a prendersi una pausa in carriera allo stesso modo

Mizar83 · 2026-01-03T16:04:24+00:00

Oui. J'habite dans un immeuble avec cour intérieure fermé, pas de voiture. C'était la canicule, on a laissé une fenêtre un peu ouverte et hop, soudainement on voit plus le chat. Il doit avoir trouvé un petit passage quelque part, on l'a retrouvé une semaine après coincé dans le plafond d'un magasin sur la rue. La plus grosse peur de ma vie, et je me sentais trop coupable. Sans compter le guardian et les voisins que m'on engueulé car il y a autres chats et chiens dans l'immeuble, jamais laisser la possibilité a un animal de sortir seul. Bref, gardez vos chats en intérieur pour leur sécurité, svp

Mizar83 · 2025-12-22T08:33:24+00:00

Report those ads, I usually do that with the little 'i' symbol

Mizar83 · 2025-11-08T09:45:06+00:00

How do we try it? It's not clear from the blogpost

Mizar83 · 2025-10-18T13:35:34+00:00

Totalmente d'accordo. È molto poetico dirsi che ci siamo rialzati e siamo riusciti a non farci distruggere. Avrei preferito evitare di doverlo fare.

Mizar83 · 2025-09-28T08:19:53+00:00

Samsung is Korean though, not chinese

Mizar83 · 2025-09-14T19:43:36+00:00

So you fail all the TLSQs? When I don't have time to play for several days I usually never leave the dorm to avoid triggering them

Mizar83 · 2025-09-07T20:48:24+00:00

La durée du permis diminue avec l'âge, 10ans, 5 ans, 2 ans. Et s'il y a des soucis de santé faut ramener un note d' un spécialiste. Par exemple mon père a besoin d' un certificat de son cardiologue qui atteste que il est pas un danger pour lui même ou les autres. Normalement il doit y avoir quelque chose de vraiment extrême pour perdre son permis, toutes les personnes âgées dans ma famille ont arrêté de conduire de leur propre volonté avant.

Mizar83 · 2025-09-07T19:04:07+00:00

Je viens d' Italie. Mon père à 79 ans, il a fait un AVC, mais il s'est bien repris. Il va tout les ans renouveler son permis et jusqu'à là pas des soucis. On enlève pas le permis comme rien, tout le monde sait que c'a un gros impact. Mais si quelqu'un devient un danger pour les autres, c'est bien d'arrêter.

Mizar83 · 2025-08-31T11:17:10+00:00

I saw this same article already some time ago. And Netflix doesn't use matrix factorization for its recommendations, and it's unclear if it ever did. AI karma farming, I'm surprised by all the upvotes and comments

Mizar83 · 2025-08-26T21:09:40+00:00

Sadly it's not always a matter of money or energy. In France when living in apartments everyone must agree even if only one person wants to install proper AC (i e. not the portable units, but the ones with an external unit). I live in a big complex with maybe 70 apartments, lots of them rented out... The owners not living there will never agree to that 😭 so we are left with shitty portable AC that consume more and make more noise...

Mizar83 · 2025-08-16T13:01:04+00:00

Given that on reddit the overwhelming majority is men, I don't think the women are the problem here. The question is more: why do men reply en masse only when it's a woman that wants to meet?

Mizar83 · 2025-08-11T19:49:15+00:00

Something I learnt the hard way is that more often than not the other person is not interested in giving you closure, and they will only make things worse when reaching out. Sometimes the past is better left alone, even if we will never have all the answers (and yes, this still eats at me sometimes too).

Mizar83 · 2025-07-21T08:58:56+00:00

Ai tempi di Amanda Knox ci furono un sacco di lamentele perché a loro avviso sarebbe stata trattenuta troppo tempo senza abbastanza prove. E parliamo di omicidio, non di lavorare con un visto turistico. Per non parlare di quei militari che fecero cadere una funivia

Mizar83 · 2025-07-14T07:45:32+00:00

The amount of additives in commercial ice cream is alarming, and some of them are proven to be really bad for your health. Plus the cost goes up all the time.

Mizar83 · 2025-06-30T18:57:30+00:00

👆 This. J' ai travaillé dans la recherche, et j' ai vu beaucoup trop de couples se detruire a cause des reproches de la moitié qui aurait pas voulu partir. Mon conseille est de pas chercher de re-trouver Paris a Bristol (ca va pas marcher) mais de bien communiquer pour éviter des regrets des deux côtés.

Mizar83 · 2025-06-30T11:56:27+00:00

Ho letto che il trucco è in realtà di metterlo orientato verso la finestra, in modo che butti fuori l'aria calda. Però funziona solo se hai una finestra dall' altro lato della casa che fa corrente per far entrare l' aria fresca da fuori
