[Ann] Fog 1.0.0-beta
by Santiago Bragagnolo Dec. 3, 2018

Dec. 3, 2018

Hi All! I have being working on releasing versions (i should do it more often). I am happy to announce Fog v1.0.0-beta. I think I found a API that i like enough. So, i took the courage to pass to 1. Thew new version changes many things: Redefines the roll of the session, it minimize the roll of the connection, it cleans up the code, it defines a more verbose but less magic API. It generates proxies for the contracts. It supports now all the types including: maps and arrays. Goodnight :) Santiago Fog Pharo Ethereum Driver Fog is a library that allows the user to connect to an ethereum based blockchain data base. Is based on the Javascript canonical implementation done by Ethereum community Ethereum Javascript API <https://github.com/ethereum/wiki/wiki/JavaScript-API>. <https://github.com/smartanvil/Fog#dependencies> Download code <https://github.com/smartanvil/Fog#iceberg--baseline>Iceberg / Baseline Metacello new baseline: 'Fog'; repository: 'github://sbragagnolo/Fog/src'; load.

How to take care that the + before a number is ignored
by Roelof Wobben Dec. 2, 2018

Dec. 2, 2018

Hello, I have a collection that looks like this : sampleData1 Â Â Â "comment stating purpose of message" Â Â Â ^ #( -8 Â Â Â +7) I want to add those numbers up but the code chokes at the + so I did this : FrequencyFinderDataÂ new class sampleData1Â Â inject: 0 into: [:sum :each | (each ~= $+) ifTrue: [sum +Â each asInteger] ] so when the each is not a +Â it must count it but still the code chokes at the + Where do I think wrong ?

VPS difficulties
by Richard Kenneth Eng Dec. 2, 2018

Dec. 2, 2018

I'm creating the competition website using Pharo and Teapot. For encryption, I'm using Pierce Ng's PasswordCrypt, which requires a 32-bit C library. This means I must run 32-bit Pharo. And this means I must run 32-bit Pharo under 32-bit Linux. Therein lies the rub... I would like to host the website at DigitalOcean or Linode or OVH. As far as I can tell, however, these services do not support 32-bit Linux, only 64-bit. What can I do?

I am not using a file, but copy/paste my puzzleInput into a puzzleInput method. Then I use lines from there. e.g. shifts ^ self puzzleInput lines collect: [ :each | ((each beginsWith: '+') ifTrue: [ each allButFirst ] ifFalse: [ each ]) asNumber ] Because the challenge is personalized and it is annoying to have to commit a supplementary file in the github repository.
