Se siete ai primi passi nello sviluppo di applicazioni web vi consiglio la lettura di SSH: What and How. Senza troppi fronzoli l’articolo spiega le basi di SSH mettendo bene in luce le possibilità offerte da questo importante strumento di lavoro. Ogni giorno molti sviluppatori web usano SSH (“Secure Shell”) per gestire i loro server, fare backup, lavorare in remoto e una miriade di altre cosette. Oggi vi spiego cos’è e da dove viene SSH..

You are a ninja-rockstar developer with a billion dollar idea. You write Ruby and Javascript. You like BDD, responsive design, HTML5 and node.js. You are really good at UX and quickly producing a prototype. You have been working on your app for a few months. Now it’s time to deploy your app. Because you are a hot new start-up, you will of course use AWS. You spend a few hours trying to figure out how many of which instance type you....

If you really care about your sanity and the sanity of those around you, you probably start most projects by creating a build script of some description. 1 If you've compiled Java or .NET, or if you read the Ant primer then you're probably familiar with writing an XML based build script. Adobe Flex application can be built in the same way, with just a few steps. Prerequisites Basic Compilation We'll start by creating a very basic build.

I thought I’d take a moment to present one possible path, or set of alternate paths, for learning Clojure, a modern Lisp implemented on top of the Java Virtual Machine. Update: Since this was written in 2012, a number of additional excellent books have come out. These include Carin Meier’s Living Clojure ; Vandgrift and Miller, Clojure Applied ; and Daniel Higginbotham’s, Clojure for the Brave and True . These are all great ch....

Problem: Derive the double angle identities $$\sin(2\theta) = 2\sin(\theta)\cos(\theta)\\\ \cos(2\theta) = \cos^2(\theta) – \sin^2(\theta)$$ Solution: Recall from linear algebra how one rotates a point in the plane. The matrix of rotation (derived by seeing where $ (1,0)$ and $ (0,1)$ go under a rotation by $ \theta$, and writing those coordinates in the columns) is $$A = \begin{pmatrix} \cos(\theta) & -\sin(\theta) \\\ \sin(\theta) & \cos(..

This is not going to be a very popular opinion considering my reader demographic, but I’ve grown a little sick of the gaming community as a whole and recent whining about Diablo 3 has triggered…well…this post. Why do so many of us have to be so negative about everything that comes out? Ok, I understand things like being frustrated about server downtime, or installation problems, or major bugs. I completely understand the frustration there..

CloudFlare is a both a proxy and a CDN (content delivery network). It was recommended to me by Magnus Bråth. Quoted from them: On average, a website on CloudFlare loads twice as fast uses 60% less bandwidth has 65% fewer requests is way more secure All for free! Never heard of them?

Usando Git capita ogni tanto, vuoi per stanchezza o per distrazione, di lanciare commit sbagliate. Stamattina m’è capitato di sistemare del codice, testarlo e fare la commit… solo per scoprire di aver lavorato sulla branch sbagliata! Non è la prima volta che mi succede e non sarà nemmeno l’ultima. Poiché ho scarsa memoria ogni volta mi tocca usare google e ripescare quei due o tre comandi utili in questi casi. Ho pensato di appuntarli qui, ..

Not many coding updates lately because of other work. I’m working on the game a little each day and will post when there’s a substantial update to make. Box2D is still driving me a little insane on a regular basis, but I’m getting the hang of it. Meanwhile, a quick overview of the past few days:

I recently read this post entitled “(Some) ORM Haters Do Get It” and I wanted to make a few points in favour of ORM’s. The author of the post argues that ORM’s are bad because of impedance mismatch.

Apparently not many. I have been monitoring how the search has been used since I rolled out code search and noticed that most people are just typing in search terms and not regex search terms. Of course this means some results are not what people are expecting. I have thus changed the way searches work. It now does an exact match of whatever it is you are looking for UNLESS you wrap your search term in / in which case it will default to a..

It was my fault that Adam became a zombie. I see it in slow motion when I close my eyes: his hand reaching out to slam against my chest and push me into the wall as he throws himself between me and the oncoming Infected. I still see the sticky spiderweb of drool and blood stretching between its teeth as it comes at us with gaping mouth and hollow eyes and I still hear the crunch of tooth on flesh as it latches onto Adam’s bare shoulder.

Recently, I have noticed that there are quite a few wrappers around git to give you a nicer interface to work with. The new commands promise to be easy to remember and make your life less frustrating. I find these a little silly because git on its own is a great tool. Here I’m going to describe how I use git to convince you (and myself) that it’s not that hard. Cloning This couldn’t be any simpler: git clone git://github.com/honza/dot....

Liza: This post, aside from this brief introduction, was written by Joseph Hewitt . I met Joseph at Interzone Games, where he tried to do his job as Creative Director while I waved bug lists at him and got on his case about design specs. He is now Creative Director at Jet Set Games, where he works on Highborn and makes all kinds of awesome stuff happen. Joseph also has his own blog: Working as Designed . Oh and he worked on one of the ..
