kehrlann··on Crazy New Ideas
It's also a common theme for Kent Beck, who "invented" extreme programming.

> i have good ideas, i just don't know which of them are good up front. hence, looking foolish is a prerequisite for looking smart.

kehrlann··on A Three-Day Expedition To Walk Across Paris Underground
It's a common game of cat and mice, still "played" to this day. When they can be bothered enough, authorities will fill a section of a gallery with concrete. And, in turn, when cataphiles can be bothered enough, they tear down a piece of an adjacent wall and dig through the dirt on the other side to go around the blocked section. I've also seen crawl holes dug under 1m-or-2m-thick rubble walls.

Amazing to see the length people will go to :')

Never heard of such an incident in the catacombs before.

In my uninformed opinion, this seems unlikely: gas pipes in Paris are buried less than 1m deep, whereas the catacombs are 10 to 30m underground, below service galleries for utilities, sewers, and even the subway.

Home-made smoke bombs are a classic (and annoying) prank in the underground. Fills an entire gallery in less than a minute: https://www.loupiote.com/photos_l/catacombes-de-paris-cataco...

Parties I was talking about look like this: https://youtu.be/6E-F-cVqubU

Nothing gets scrutinized - it's illegal to go down there anyway. Folks down there are not always safety conscious or very responsible :o)

Sometimes there are parties with tens or over a hundred people in a big room that only has two crawl holes to exit it.

About fire safety, well it's pretty damp down there, mostly with rocks and dirt. Can't picture a whole room catching fire... But I'm no expert in fire safety.

kehrlann··on Ask HN: Have I lost my skills in programming?
If you have trouble picking a project, code katas are really fun to try.

The instructions are broad enough that you can solve them in different ways. Take a crack at one, solve it. Reflect on what was easy and what was hard or painful. Come back some time later, re-do differently - maybe this time optimising for what was hard the first time.

Also you can take a look at classic data structures and reimplement them from scratch. Don't look at the current implementation, just at how it's supposed to work, and try implementing a List (array or link based ?), a Map (hash, tree?), etc. Then you can compare with the existing implementation.

Or play those coding games you're talking about ! Start easy, work your way up. When it gets too hard, take a break, try another game. Let it rest a bit, come back to it when you have fresher ideas in 2 weeks time.

In general, flex your muscles where you think you're lacking. E.g.: think you overcomplicate ? Do a kata, finish it. Then look at it and try to simplify what you've done.

Good luck in your practice, I hope you enjoy it :)

kehrlann··on Strato Pi – An Industrial Raspberry Pi
I've had numerous failures on older RPi models due to SD card corruption, even in non-write intensive contexts. Not sure this is good enough when you want reliability...
kehrlann··on The First Rule of Microsoft Excel: Don’t Tell Anyone You’re Good at It
Joel Spolsky used to be a Program Manager for Excel. He has a great, 1h long video doing an Excel demo a few years ago - here, now YOU can be the Excel guru https://youtube.com/watch?v=0nbkaYsR94c
kehrlann··on Bloated
Lighthouse (now the Chrome dev tools "audits" tab) makes it really easy to trim down your site to the bare minimum. I've using on my personal blog, it's actually quite fun to work within constraints :)
kehrlann··on The Case of the Broken Lambda
Batteries included, except when it's not :)

Cross platform Python is tough, especially when you use dynamically linked C libs on a platform that can change versions without warning.

kehrlann··on France bans smartphone use in schools
There was no law about this but school staff sometimes enforced it anyway.
kehrlann··on Why Is Front-End Development So Unstable?
I believe classifying libs/frameworks by number of stars is not enough ; "when" these frameworks got stars, or how many stars they got in the past 6 month, is probably important. Not sure jQuery or angular 1 got many stars lately...
kehrlann··on Google’s Airpods competitor do real-time language translation
Isn't it already happening ?
kehrlann··on Floating Point Visually Explained
Ooooh I see. I like it, thanks !
kehrlann··on Floating Point Visually Explained
I guess I'm not math-y enough so that I intuitively understand the simple math formula.

On the other hand, I like his window image : e.g. I understand better how, the further you get from 0, the more your precision goes down, because "bigger windows, divided in the same number of buckets".

kehrlann··on Floating Point Visually Explained
Best simple explanation I've seen so far.

I highly recommend Fabien's Game Engine Black Book. I'm halfway through it, and it's really fun. I've only been a software dev for 6 years, so looking at how things could be hacked around in the 90s to squeeze every drop of performance out of very constrained devices is fascinating.

kehrlann··on Cost of iPhone X in 1957
Agreed. Discussing trends (speed of progress) with just two data points doesn't work.
kehrlann··on A French Grocery Chain Is Trolling Amazon Go
But if it's lunch time, everyone is waiting in the same fast line, which defeats the purpose ...
kehrlann··on A French Grocery Chain Is Trolling Amazon Go
Slightly different use case, though. Say I want a sandwich and a drink, I want that right now, not delivered to my house in one hour.

Funny PR, though !

kehrlann··on Machine Learning for Everyday Tasks
Agreed. Also, they don't discuss how they chose their features... It seems the problem was already solved before even applying ML to it. Maybe the example is too naive ?
kehrlann··on Thinking at the Margin: It's Revolutionary
Such an educated man might go a step further than just answering the question, and rephrasing it... Maybe it's not just about earning more money, but disproportionately higher standard of living. And speaking about those inequalities shifts the debate - since they earn so much money, they could contribute more to society, say through taxes ?
kehrlann··on H-1B Willful Violator List of Employers
Mmmh, not being familiar with US immigration laws, I'm not sure I get everything. Is this about companies who illegally "import" foreign workers when they could have recruited US citizens ?
kehrlann··on Brussels Rocked by Terrorist Attacks
Syria for sure, and there's also Libya.

Ah, and don't forget the European border policies regarding (mostly Syrian) refugees...

kehrlann··on Shout: The self-hosted web IRC client
Interesting app, I've been using it here and there, mostly with a self-hosted IRC server. More or less a completely self-hosted chat system.

The UI is clean, and once it's up and running the experience is pretty smooth for users. However : - Quite a hassle to install and maintain your own IRC server ... - The server stores everything in memory. Pretty neat the first time you use it, but it tends to leak. - Your user DB is just a bunch of json files, with no extensibility built-in. It could really use a "users" plugin, that connects to an external auth system ...

kehrlann··on Rapidoid – No-Bullshit Web Framework for Java
Too bad it doesn't have swagger integration (yet).

Love the easy, clean API - it's great for a reasonably sized project.

kehrlann··on The Exploitation of Paris
To be honest, the shock and pain and angst and awe we feel here in Paris is so overwhelming that I feel too numb to realize that, Yes, of course, people will use this event to promote their own ideological agenda... It makes me sick, truly.

This should be a call for peace, not war.

kehrlann··on Facebook is able to identify music and TV when writing status update
Mh true. But will it remain opt-in ?
kehrlann··on Facebook is able to identify music and TV when writing status update
Is it just me or is it _beyond_ creepy ?

Location, sound ... soon they will be collecting biometric data as well, "just to get room temperature, promise".

kehrlann··on Automating Tinder with Eigenfaces
I am not too creeped out by the concept of this bot (actually, I find the whole idea amusing). I can understand why people would find it creepy, but I feel that the creepiness comes from Tinder rather than the bot ... It's only possible because of Tinder and the way it makes users interact with each other.

Not a Tinder user myself, so I guess I'm biased in this case.

kehrlann··on The Market Where France’s Top Chefs Buy Their Food
Agreed.

Most restaurants in Paris get their food there. Wholesale, fresh, cheap.

But well, I guess it makes for a good title :o)
