Lately I have been working on building out my first non-trivial application with node. It has been a very interesting smashing of my brain cells. Coming from a strictly typed language and moving into a prototype based language has removed a lot of my tools from my tool belt. But of all the changes, I think it is the lack of IoC that is hurting me the most. Getting out of your comfort zone will also reveal your programming assumptions.

After reading the blog post, I still don't have an answer to "what the hell is he talking about?"

Metaphorically speaking, that is true of wetware too!

Some say that API design is one of the hardest things in programming. A few even go as far as to say you should have at least 10 years of experience to even attempt it. While I think this process can be sped up almost an order of magnitude by good mentorship, at one time or another we’ve all suffered under the API of an inexperienced programmer. Though, this does raise the question: what exactly is it about building libraries that can take up to 10 years to learn? Bad ideas usually seem like good ideas... until you have to use them.

Well, speaking from experience, just because you have a set of functions that does what you want doesn't mean you have an API. You have to learn to think "how would someone else use this?" It's then that you begin to realize that your initial API isn't abstract enough, doesn't provide enough event notifications, doesn't provide ways for someone else to easily customize the behavior. Those 10 years are from using enough of someone else's API's to learn what not to do, and then figure out how to do it better yourself.

Building an API requires 2 main things>
1. Know exactly your goal
2. Give others the freedom to use it however they want to
In a way this seem like two conflicting defenitions but they aren't.
I don't know if you need 10 years of experience for that. You sure need a lot of experience using APIs and you'll have to crack your head building your first ones to be open minded enough for this.
Another pitfall developers usually fall into is confusing flexibility with complexity.
You don't need to be over complex to deliver flexible APIs.
Keep it simple. A good practice are the use overloads.
Have a good critical look at the .net Framework design... it's probably the most complex API I'll ever work with 
I usually say that it's like a war game, you always have to be several moves ahead of your "enemy"

Sagas come out of the realization that particularly long-lived transactions (originally even just inside databases), but also far distributed transactions across location and/or trust boundaries can't eaily be handled using the classic ACID model with 2-Phase commit and holding locks for the duration of the work. Instead, a Saga splits work into individual transactions whose effects can be, somehow, reversed after work has been performed and commited. Tune in next week when you'll hear the thrilling conclusion to this pattern...

So, a saga is merely a repackaged commit-system? With the explicit explanation that you should use the "smallest" set of commands in a transaction possible?

I gave a talk at #DDD10 this Saturday about keeping JS sane. I had some questions after about the list of things I ran through so documented in all its glory are my current thoughts on development with a dynamic language like JavaScript. Javascript sucks and it doesn’t matter (that it sucks)

These operator keywords are a powerful tool, one that many of us don’t know about or we forget that they are available to us. Let’s try to make better use of these native language features, as they will help us improve our class design by keeping all of our object’s conversion concerns in one location. Until next time, may all your code compile, and all of your unit test pass!

Let us now, step by step, our first sketch to use the shield using the Arduino IDE version 1.00. We will write a program that when it receives a call from a preset number (stored in a specific location on the SIM), rejects the call and sends an SMS in response to the caller with the value read from an input. That's right: turn your Arduino into a phone... with working example code.

Like everything they build, engineers at NASA's Jet Propulsion Laboratory (JPL) designed Curiosity's Sky Crane landing system to work. But nothing is guaranteed in spaceflight. The team wouldn't know for sure whether the mission's entry, descent, and landing (or EDL) was successful until they got confirmation from the rover. The problem was that Curiosity's landing site in Gale Crater would be out of range at touchdown, so the team brought in a communications relay: the Mars Odyssey orbiter. It was a simple and obvious solution, except that Odyssey experienced its first ever malfunctions weeks before Curiosity's landing.... You have to have been out on a long patrol to appreciate this properly.

Several weeks ago Steven Degutis posted the slides from his excellent presentation, The quest for the perfect programming language. In reading his slides I was reminded of a blog post made back in 2007 by Steve Yegge called The Next Big Language. With the benefit of hindsight that history provides, I would like to revisit the major points of Yegge’s Next Big Language, and address them in the context of Go. Is Go the next big thing? Probably not, but an interesting read nonetheless.

Node is popular with new programmers, and it’s popular because it makes concurrency easy. Yet strangely it isn’t a good fit for high concurrency applications because it isn’t robust. And how many new programmers are jumping straight into concurrency? What to make of that? In there lies, I believe, part of the secret of Node’s success. Node.js, aspirational marketing and you.

I like Ben Brown's take on password-less logins, which motivated me to explore his direction further: Could we skip usernames and all the other steps too? My idea lends heavily on his work, OAuth (and others I’m sure.) Let’s turn to the server to learn how it works... Ah yes! If only he'd used his anti-login raygun for niceness instead of evil!

Article from http://news.cnet.com/[^]
Only hours after Oracle released its latest Java 7 update to address active exploits, security researchers found yet another vulnerability that can be exploited to run arbitrary code on systems that have the runtime installed.
Oracle's latest release of its Java 7 runtime has come under scrutiny in the past few weeks after it was found being actively exploited in malware attacks that target Windows systems. While so far the vulnerability has only been found being used against Windows, other platforms such as the Mac OS could potentially be targeted through the same exploit.
In response to these findings, Oracle broke its quarterly update schedule for Java and released update 7 for the runtime; however, even after this update, yet more vulnerabilities have been found.
According to MacWorld, the Polish security firm Security Explorations is claiming to have discovered two new vulnerabilities in Java 7, which so far are proof-of-concept exploits that can be used to break the Java 7 sandbox and execute code. However, as with any vulnerability this opens new avenues for malware attacks.
Security Explorations is keeping the details about these latest vulnerabilities secret until Oracle addresses the problem, and has only stated that when exploited they allow rogue Java applets to break the Java sandbox and execute arbitrary code on the system.
Being only proof-of-concept attacks means that for now they should not pose much of a threat to Java users, and Oracle should address them in future updates. However, Oracle has recently met some criticism for its lackadaisical approach to addressing some known exploits. According to PCWorld, Oracle has known about these and other exploits since April of this year, and has not taken steps to close them.
These latest developments serve as a warning against using Java when not needed and also prematurely updating Java. Java 7 is still very early in its development, being only the seventh release so far, whereas prior runtimes have received over 30 updates to patch and manage vulnerabilities. As a result, if you need Java then you might consider installing a prior runtime version that has been well-tested, but if you do not need Java then you might consider avoiding installing it or removing it from your system if it is already installed.
Java 7 is an optional third-party installation for its supported operating systems, so only those who have installed it should be cautious of these vulnerabilities.

A total of 17 of 20 government departments face disruption from April 8, 2014, when Microsoft support for Windows XP expires. The system will also be vulnerable to Trojan horse-style viruses.

Same problem everywhere; I expect some local government-departments will be asking to migrate their VB6-code somewhere in 2016.

The information in this article is how commonly used Windows Phone APIs and XAML features map (or do not map) to their Windows 8 counterparts. There won’t be a lot of dialog in this article. I’ll mention what the API is used for, show the Windows Phone version and show the Windows 8 version. If there are any important tricks to note, I’ll list those too. Which raises the question: why do these APIs need to be different at all?
