I woke up last night after a weird dream and wrote this down (I guess falling asleep with your laptop open on the bed comes in handy), editing typos etc out this morning. Rereading it today I can barely remember any of the actual dream. I wish I could make it come back and find out what happened.

As I’ve gotten over my jetlag I’ve been ramping up the JS work again. There are now two projects to work on and I won’t be posting much about the second one specifically, but will still be writing about the general JavaScript learning progress as well as posting Gwen updates.

I linguaggi di programmazione ‘moderni’ a confronto: PHP vs Ruby vs Python. Lo scorso gennaio Udemy ha rilasciato una bella infografica che confronta i tre linguaggi sotto molti aspetti. Ne esce una fotografia secondo me interessante dell’attuale panorama dei linguaggi interpretati:

I had an annoying problem on Windows 7 x64 with Helios x64 where I had pinned Eclipse to the taskbar but would see two icons whenever Eclipse was running. I found that the following workaround works with the option “Always combine, hide labels” for taskbar buttons. You must specify a -vm argument in your “eclipse.ini” file (in your Eclipse directory). The -vm argument in your “eclipse.ini” must point to the bin directory of your JDK or ..

If you are interested in node, you know that NodeJS uses an event driven I/O model and it is single threaded, so it is not meant to be working multi-core. However, by using the clustering support, you can bump your applications speed. I will give a a plain hello example, however consider that you will never send just hello world to anyone in the world without any background processing like database connections, cache connections, file opera..

I hate giving promises for things I can’t control. I can promise that I will attend a party or that I will set aside time to help you with your problem. I cannot promise that the party will be fun or that your problem will be solved. Giving promises on effort is honest, giving promises on outcomes is dishonest. A team that commits to an estimate is promising something they cannot control.

Amazon EC2: Quanto si risparmia con le Reserved Instances rispetto alle classiche On-Demand?

Amazon offre sconti significativi per chi sceglie le istanze riservate al posto di quelle on-demand. Dal punto di vista finanziario, e se avete intenzione di usare EC2 per almeno un anno, passare dalle istanze on-demand a quelle riservate potrebbe aver senso. Sborserete una cifra più alta inizialmente, ma il costo mensile si ridurrà sensibilmente. Per quanto io ne sappia il tool sviluppato da Mike Khristo è il primo che consente di confr..

I seem to have not blogged about this, but Open Advice , our book on Free and Open Source Software: what we wish we had known when we started , was published last month. The book was edited by Lydia Pintscher and includes essays from 42 authors , many of whom you'll recognize if you tend to go to FOSS conferences. The LWN book review concludes: Open Advice is a book that will be helpful to those who are new to FOSS, but, becaus....

Problem: Write a program that shuffles a list. Do so without using more than a constant amount of extra space and linear time in the size of the list. Solution: (in Python) import random random.seed() def shuffle(myList): n = len(myList) for i in xrange(0, n): j = random.randint(i, n-1) # randint is inclusive myList[i], myList[j] = myList[j], myList[i] Discussion: Using a computer to shuffle a deck of cards is nontrivial at first glance for..

Usare Dropbox come repository Git remoto Recentemente, più che altro per curiosità, ho giocato con una terza opzione: Dropbox. Per me Dropbox è uno strumento indispensabile sia per il lavoro che per le mie cose personali. Su qualunque computer io sia, ovunque mi trovi, grazie a Dropbox ho accesso al mio materiale. Dunque, mi son detto, perché non usarlo anche per il codice, pur senza rinunciare al controllo versione offerto da Git? ..

I attended a talk at the Toronto Agile Tour on Deliberate Practice that focused on TDD Games and other programming challenges like Kata. Among the challenges were things like solving a problem without using the ‘if’ keyword, or without using primitives. Solving simple problems using these challenges makes us better programmers because they force us to come up with multiple, creative solutions to the same problem. Here’s my solution for..

I build software for a living. This means creating the new generation of Content Management interfaces in the IKS Project and developing custom client applications at Nemein . As my office is where my laptop is, none of this work is particularly tied to a physical location. And as much of the work is communicating, I end up spending quite a lot of time traveling between meetings and conferences. For this my previous home town....

Anni fa JavaScript era considerato più che altro una seccatura: produceva queste animazioni e trailer per il browser e poco altro. Ora tutto è cambiato. JavaScript è eletto a linguaggio funzionale di prima classe e in rete sono disponibili risorse innumerevoli . Condivido con voi alcune delle mie fonti migliori, che uso per tenermi aggiornato su librerie, progetti e JavaScript in generale. – Rob Bazinet

Sorry, no news to report on Lemma this week. School is keeping me busy. But I thought I'd share some of the projects I'm working on for school, since they're kind of cool and actually somewhat related to Lemma. First up: a 3D rapid prototype of the original toon-style Parkour Ninja! Here's the model rendered in Cinema 4D: And here it is printed out in 3D:

Eh…this started out being a brief update from the past week and turned into an ongoing update stream of notes. I didn’t have an Internet connection available for much of it, meaning this post may be a bit weird as parts of it were written at different times, but it’s mostly just for me to be able to go back and review my progress.

As a user, I can add social security number, so patient logs have social security numbers As a developer, how would you react if you were given this user story? Would you throw it back in the face of the product owner, or would you try and understand it? How about the following dialogue? Developer: “What are we hoping to achieve with this story?” Customer: “We hope that the patient logs will have social security numbers.

For the past N months, it seems like there is no new technology stack that is either hotter or more controversial than node.js. node.js is cancer! node.js cures cancer! node.js is bad ass rock star tech!. I myself have given node.js a lot of shit, often involving the phrase “explicit continuation-passing style.” Most of the arguments I’ve seen seem to center around whether node.js is “scalable” or high-performance, and the relative merits o..

Proprio un anno fa presentavo Sublime Text 2. Dopo dodici mesi ho pensato di fare il punto della situazione. Si sono susseguiti una serie di aggiornamenti importanti, il prodotto è più maturo e devo dire che in questo periodo non mi ha affatto deluso: è ancora il mio editor di codice preferito. Nel frattempo Sublime Text 2 è diventato mainstream. Me ne sono reso conto in questi giorni, quando articoli, recensioni, trucchi e suggerimenti s..

Se avete già scaricato il Piccolo Libro di MongoDB vi consiglio di aggiornarlo con la versione odierna. E’ stato aggiunto un capitolo (MapReduce) misteriosamente assente nella prima edizione. Grazie a Walter Tommasi per la preziosa segnalazione, e a Git per averne consentito il recupero in extremis.

Kids are never the problem. They are born scientists. The problem is always the adults. The beat the curiosity out of the kids. They out-number kids. They vote. They wield resources. That’s why my public focus is primarily adults.
