Ce n'est pas parce que les choses sont difficiles que nous n'osons pas, c'est parce que nous n'osons pas qu'elles sont difficiles.

Rendre l'expérience utilisateur audacieuse

A user interface is like a joke. If you have to explain it, it’s not that good.

— Martin LeBlanc

pour être efficace, l'important n'est pas de savoir faire tout ce que tu peux faire avec tes outils, mais plutôt de connaître tous les outils existants, leurs avantages et leurs inconvénients; connaître leur utilisation viendra en temps voulu.

je vais chercher l’argent où il se trouve (dans la pub) et je m’achète du temps libre

Entreprise lifecycle

Il existe depuis longtemps un cycle de vie pour les entreprises : les jeunes entreprises innovent, sont avides de cash et se cherchent désespérément des financements. Certaines y parviennent, vendent leurs produits et se retrouvent à gagner plus d'argent qu'elles n'en ont besoin. Les grandes entreprises prennent cet argent et l'investissent dans des produits encore meilleurs, emmenant l'entreprise vers de nouveaux sommets. [...]

Mais, inévitablement, les technologies des entreprises deviennent standardisées et banalisées. De nouvelles technologies, plus brûlantes, prennent leur place, et l'entreprise n'attire plus les meilleurs travailleurs, parce que, justement, elle ne représente plus la prochaine chose à la mode. Les nouveaux produits connaissent une perte de vitesse, les vieux produits ne sont plus aussi rentables que par le passé (car les concurrents comprennent comment faire quelque chose de mieux), et les marchés et les consommateurs passent à autre chose.

Fullstack Developper

Aka Full stack or full-stack developper

Being able to do it all vs being able to be talented in all is a huge difference. It's not related to language, frameworks or tools, but concepts like performances, security, accessibility, ergonomy / UX, efficiency (multiple ways to do the same thing, but with diff. impacts), load balancing, design, etc.

It's like a One-man band, can't easily play a Symphony or even not at all.

More a lego player/builder than a brick craftsman/manufacturer

Fullstack dev can create a prototype, but not a large scale project solo

Full stack = for prototypes, MVP, only one dev; frontend, backend, devops Not for team or at least without expertise requirements

Full stack devs originate from startups where you have to get your hands dirty in all the fields if you want to succeed, but as soon as you're able, you have to hire specialists if you want to have your product follow the highest security, efficiency and design standards, packed in a good, presentable but not bloated UI.

A full stack developer is “A developer who can introduce a bug to every layer of the software stack.”

Site off-line Sorry our site is offline as we refused to pay our web developer and he put this here and then changed the passwords! You could always try calling or emailing us but maybe its better you just go to switch as they are much more professional, we suck.

If you are another web developer that has been paid to change this then make sure you get paid up front, trust nobody.

Project phases

Un devis et bon de commande par phase : découper le projet en plusieurs phase/devis(avenant)/paiement. Ce qui permet 1 paiement (et 1 acompte) par phase. Ainsi, ne pas engager la suite que si la première partie est validée / payée. Cela répond au besoin de flexibilité de paiement dont le client se réclame.

Price

See Time estimation

Always show prices.

It discourages people who aren’t the target market. It's also about opening a dialogue with your users/customers to learn more about them. But it's maybe not what the target what first.

I always interpret "Request a Quote" to mean "too expensive, find a competitor with pricing listed on their site".

Kyle Drake sur Twitter : ""

SpaceX or Boeing list prices of expensive vehicles. There's no excuse for the lack of price transparency

If your first question is how much does it cost, you're not the customer we want

— CEO of Timeshare Resorts Inc.

Budget and payment

How much:

jour/homme -> jour/personne

  • Projet sous 1000€ : payement avant commencement (évite les ajouts non souhaitable de dernière minutes) -> au dessus prévoir un devis détaillé, cahier des charges

  • Préférer le taux horaire plutôt qu'un prix global

  • Négocier le champ d'application, pas le prix

If you meant the following… then it would be X hours. If this is not what you are aiming to do, then could you clarify…

You wouldn’t expect an accurate quote from a contractor if you said “I want a house with a kitchen, bathroom, and living room – how much will that cost me?”

  • Versement d'un acompte de 30% à la commande

  • Paiement de 60% a la livraison

  • versement des 10% restant à la facture

it's a "big" French book publisher, asking for free illustrations to see if I could be a good "fit"... for a book they're making. And if they happen to like it they may hire me for the book. Funny thing is I've done very similar illustrations. but apparently it's not enough. And the book is gonna be a best seller! So why shouldn't I do it?

  2. NE M'ENVOYEZ PAS VOS OFFRES DE MISSION DÉVELOPPEUR ANGULAR (pitié). Je ne fais pas de développement JavaScript (Backbone, Angular, React…), j’utilise JavaScript essentiellement pour dynamiser mes pages (avec jQuery le plus souvent) et non pour traiter de la donnée.

Can you give me an estimate on how long it will take you to fix this bug? That's like asking how long it will take to find my keys.

Making artwork, on its own, is challenging. If you want to develop the business side of that, it's a whole other thing. You need to be prepared to dedicate time to things like:

  • Building a website

  • Ordering prints

  • Buying shipping materials

  • Packaging art for shipping

  • Going to the post office, filling out customs forms

  • Posting your artwork online on various platforms

  • Connecting with other artists, supporting them, and learning from them

  • Doing taxes

  • Responding to loads of random emails

  • Photographing your work

  • Editing photographs of your work

  • Keeping your work organized, accessible, and backed up

  • Framing your work (buying materials, cutting mats, etc)

  • Hanging your work for shows

  • Talking with folks who enjoy your work during opening receptions, studio tours, interviews, etc.

  • Sending invoices

  • Negotiating commissions and licensing deals

  • Speaking about your work at events

  • Delivering your work in person

  • Reading about all the things you don't know about running a business, like marketing, accounting, and sales

  • Writing about your work, including about a dozen variations of an artist's statement, which is possibly the least fun thing to write

This adds up to a large percentage of your time, often more time than you get to spend creating artwork.

Evidence based scheduling

The estimation system takes 100 velocities calculated from the developers history. Each velocity is the ratio between estimated time and actual time for a given task. [...] It just means that because the interruption affects the velocity for a certain percentage of the tasks, the interruption will be appropriately represented in estimates that are based on 100 random velocities from the developers history.

Time estimation difficulty

I no longer quantify problems in the length of time it took to solve them, or the lines of code. My new measurement is "Tabs".

This was a 30 tab problem. I had to go in deep.

I solved that one with only 1 tab.
