janus··on Making Machines Move
he's the author.
janus··on Seeing like a bank
It depends on where you live. In my country I would never take a call from a bank at face value and would always expect they give me a phone number to call back, and that better be an institutional number. Phone fraud is rampant.
janus··on How to find a lost phone in a no-cell-coverage camping site?
Ha, last winter I lost my phone while snowboarding in the last 300-500m before mountain base. I noticed because I was listening to music with my airpods when I got to the bottom the music had gone silent. Thankfully I had my Apple watch with me, so I immediately got off the board and start running uphill while incessantly spamming the "ping my phone" button. At some point I saw in the watch screen it briefly connected and then immediately disconnected again. I realized somebody had probably grabbed it and skied by me. I went back running to the chairlift while still spamming the button and finally found the person who had grabbed it, a few seconds before he got into the chairlift. I felt that day that the watch investment had been worth it hah.
janus··on Ruby 3.2.0 is from another dimension
Progress is really good, in this RubyKaigi talk there’s a great demo showcasing the official rbs with vscode integration https://youtu.be/4E4TRgMDYqo
janus··on We chose NanoIDs for PlanetScale’s API
This is great, except for the additional query each time a record is instantiated in the rails concern. That might cause some performance problems in high traffic.

Perhaps it’d be better to attempt the insertion and change the id only if there’s a colission detected with a uniqueness constraint

janus··on Chernobyl power plant captured by Russian forces
You don't want to bomb the Chernobyl exclusion area.

So it's a perfect place to station troops and military arsenal

janus··on The age of electric flight is finally upon us
Actually, gliders with water ballasts have the same L/D full or empty. The difference is that they can fly faster when the tanks are full, but they don’t travel larger distances
janus··on Why things might have taken so long
Well, leaving aside the problem of taking off (which today is improving thanks to electric motors), I guess one could say that gliders[1] are the closest we can have to human-powered flight and it's highly efficient in terms of energy consumption

janus··on Ask HN: What's your primary development laptop?
A 2015 Retina Macbook Pro 13
janus··on The Suicide of Venezuela
Argentina dodged that bullet. It was heading the same way.
janus··on A Tube map of the London Underground that's more useful than the 'official' one
This is useful citymapper.com/london
janus··on Show HN: LibreBoard – An open-source clone of Trello
It's so sad that such great work can bring so many negative repercussions just because the project creator's decided to blatantly rip off Trello's assets.

The project would be under such a different light had they decided style it themselves... I think they're so much better than this.

janus··on What Do Blind People Actually See?
This story reminded me of the guy that had a magnet implanted in his pinky finger, who was then able to sense electromagnetic fields and other stuff

janus··on OpenStreetMap is now navigation-ready
What's a good navigation app for Android that works outside the US? (Scout doesn't)

I have a couple of apps in my phone (Navigator and Waze), but the UI is really cumbersome compared to Google Maps. I use them because OSM maps are better in small tows in my area than Google Maps, plus you can keep offline maps.

Interested in work as a ruby, javascript developer. I'm very passionate about technology. I'd be very interested in a position in Berlin, Germany or similar.

janus··on A Vim Tutorial and Primer
thanks, I'll give it a try. When I briefly tried NERDtree, my issue was how to switch back and forth between the tree and the opened files list
janus··on A Vim Tutorial and Primer
As always, what loses me on vim is that I'm not sure what's the easiest/best/common way to have a "project directory" open and quickly open one of the files inside that directory... no basic tutorial seems to tackle this, yet it's essential to migrate from any other editor you use as a programmer...
janus··on Zurb Foundation 5 Released
Camel cased would actually be javaScript
janus··on Startups Like Berlin Because Visa Rules Are Nothing Like the U.S.
As a argentinian programmer with italian citizenship that is considering leaving the country for Europe, are there any sites / forums or communities where I can contact startups or companies residing in Berlin?

I'm a web developer with experience in Ruby, Rails and Javascript

janus··on Argentina's Currency Black Market
Argentina's currency black market is just an acknowledgement of the actual price of the Peso that countries in the border have. You can LEGALLY exchange 1 US dollar for about 10 ARS in Uruguay http://www.bcu.gub.uy/Paginas/Default.aspx
janus··on Essential Tools for Starting a Rails App in 2013
I've grown to like Authority more than Cancan. It does 'less' magic but it's way more declarative and allows you to be really explicit on what you want to check.
janus··on Hacking the OS X Kernel for Fun and Profiles
Will this also allow me to scale the cpu? I was already able to change the fan's speed .... thanks
janus··on Hacking the OS X Kernel for Fun and Profiles
I don't mind getting my hands dirty at all. I'll see if I can find any more info about this kext, thanks :)
janus··on Hacking the OS X Kernel for Fun and Profiles
great, thanks for pointing it out.
janus··on Hacking the OS X Kernel for Fun and Profiles
Can someone explain what this patch actually does? I have an old Macbook Air with a malfunctioning sensor that cause the CPU to always run in powersaving mode (capped at 800 mhz), so it's basically unusable under OS X.

I have walked around this issue by installing Linux which allows me to tune the CPU governor manually, and it uncaps the artificial limit that the malfunctioning sensor puts.

Would this patch allow me to do something similar in Mountain Lion?

janus··on Rails 4.0: Final version released
The only issue that's been biting me when using ActiveModel::Serializers and AngularJS is that we must manually return the json with the root: false option set, otherwise the AngularJS $resource provider doesn't work correctly.
janus··on How OS X “Mavericks” works its power-saving magic
Because the usage is percentage based, of course it depends entirely on which CPU you currently have. I imagine 3-5% of the latest Macbook Pro Retina i7, isn't the same as the 2010 Macbook Air's Core 2 Duo.
janus··on Forget flat design. Design in a 1995 style for full impact
This one is awesome http://www.wingsandwheels.com/wantads1.htm
janus··on Show HN: A high performance airplane for the price of a luxury car
This is truly amazing. This airplane weighs less than one of the most famous and popular gliders, the PW-5 Smyk.

I hope one day to be able to buy one of these to go back and forth from work.

Any plans for a dual seater version? That would be awesome and would totally destroy the high end coupé cars market

janus··on Ask HN: How to write the first line of code in a new startup?
Just do it as a if it was another application, then refactor when needed. The important thing is to ship, not to create the most beautiful code in the world.
