Silverlight 5 è in dirittura d’arrivo. L’ultimo aggiornamento del plug-in Microsoft sarà ultimo  in tutti i sensi dato che a quanto pare non ne seguiranno altri. A sostenerlo è ZD-Net per bocca di Mary-Jo Foley, di solito sempre ben informata su quel che succede nei corridoi del gigante di Seattle. Diversi partner e clienti mi hanno detto di aver saputo da fonti Microsoft che Silverlight 5 è l’ultima versione di Silverlight che Microso....

So yesterday I was bored and asked my friend what I should do. She replied "I don't know, draw ASCII art or something!" and sitting there with the terminal open I kind of wondered what it would take to write one of those image to ASCII scripts. 20 minutes later I had the following PHP Shell Script! It works by simply sampling the saturation of every X th pixel and mapping that saturation to a character from an array. There is no nearest....

NoSQL has long been a trend that many have talked about. While there’s a place for various key-value stores and tools such as memcache and redis, this will address most specifically how NoSQL is attempting to replace a traditional database. I’ve long been a fan of postgres and in general traditional relational databases. In a broad sense traditional databases offer multiple things. RDMS Data guarantees The current major SQL da....

In my earlier post on Teams and Tools at Heroku , I mentioned how we value engineers’ time; their work has enabled us to build a great platform. As a result of what we’ve built, we’ve had great growth both of our platform and of our teams internally. With that growth inevitably comes different distractions on engineers’ time. Despite how a manager may plan things, engineering work needs long periods of uninterrupted time. To ensure that no....

2011/11/8 05:01 AM NZDT Christchurch Spring in Christchurch Woke up a few minutes ago and started thinking about a blog post. I would have happily slept more but my body tells me that’s not going to happen. It’s quiet here, with the only sound the faint snoring noises coming from the next room over. I’m at a hotel in an area of Christchurch called Papanui whose distinguishing feature seems to be a shopping district with a mall ....

Note, while the problem below arose in ring theory (specifically, Euclidean domains), the proof itself is elementary, and so the title should not scare away any viewers. In fact, we boil the problem down to something which requires no knowledge of abstract algebra at all. Problem: Show that the ring $ \mathbb{Z}[\sqrt{2}]$ has infinitely many units. Solution: An element of $ \mathbb{Z}[\sqrt{2}]$ has the form $ a+b\sqrt{2}$ for integers $ a..

E’ uscita ieri la versione 1.1 Alpha dei Python Tools per Visual Studio, il plug-in open source per programmare in Python con Visual Studio 2010. Migliorie e molte nuove features per la IDE ma la novità più interessante sono senz’altro PyKinect e Pyvot, due librerie che consentono rispettivamente di lavorare col Kinect SDK e di interagire con Excel via Python.

This is a list of my favorite thought leaders in the realm of education reform. You can skim through and individually follow them or you can follow my list.

Recalling our series on Conway’s Game of Life, here is an implementation of Life within Life. Unfortunately, it does not “prove” what I hoped it might, so unless a reader has a suggestion on what this demonstration proves, it doesn’t belong in the proof gallery. But it sure is impressive.

Heroku is a largely agile company, we work in primarily small teams that talk via api and data contracts. Its also a company comprised primarily of engineers, even product managers often write code. Heroku as a platform drives many of the features not from top down, but from bottom up based on engineers desires or skunkworks projects. There’s many valuable insights into how Heroku runs efficiently for engineering. I’ll be diving into many....

Ai primi di ottobre TechCrunch riportava una notizia interessante: negli Stati Uniti ci sarebbe carenza di sviluppatori .NET. La piattaforma di recruitment Dice dichiara che le offerte di lavoro .NET aumentano del 25% ogni anno, e che la gran parte delle ricerche sui loro database riguarda skill .NET. Ai primi di ottobre 2011 sarebbero state oltre 10.000 le richieste inevase di figure professionali .NET. Notizie di questo tipo vanno prese..

T minus four days and I’m getting ready for yet another trip to the Pole — this one is number ten. I guess I’m not sure what I’m going to write about on this trip, yet, but I will be posting updates as time allows. Just spent a few hours getting the blog software up to speed (there are lots of improvements I want to make if I have time). It’s interesting coming back to a project after nearly a year and seeing what I’ve learned since then. ..

Now that you have you system and project environment all setup you probably want to start developing. But you likely don’t want to start writing an entire project fully from scratch, as you dive in you’ll quickly realize theres many tools helping you build projects and sites faster. For example making a request to a website there’s Requests , for handling processing images there’s Python Imaging Library , or for a full framework to help y....

It seems Godaddy has finally plugged a hole in its whois privacy system which allowed users to see the domain owner's email address domain (ie ****@kevinohashi.com) if they tried to retrieve passwords. Now it requires the user the enter that email address instead of verifying that the asterisked email address is in fact the proper domain associated with the account. I highlighted the fix in the image below. Privacy at Godaddy just got a ..

Jubbin has been trying to find techno music that I would like. I’m picky - I don’t like female singers and I prefer kind of a specific sound. All of this Twitter YouTube linkage to music videos made me think - how do I discover new music that I like? Mostly nowadays it’s through hearing about a band through another band, or liking music in a movie and getting the score. Or, a lot of the time, clicking through related YouTube videos until I..
