You will need both Java JDK and JRE.

${java.home} specifies the path to the current JRE_HOME environment use with relative paths to get for example: ${java.home}../bin/java.exe

And with a JDK for example in c:\jdk the maven ${java.home} is pointing to c:\jdk\jre"

mcansky : Git is cheap !

mcansky : Git is cheap !: "TL;DR : committing and branching is cheap with git so stop worrying about it : split your features into small bricks and commit early and often.

Git is a wonderful tool, yet many of us use it like a glorified svn. Git is not only about features but also about flows and we should pay more attention to that when learning or teaching about git.

Kill the Zombies in Your Code | BitNative

Kill the Zombies in Your Code | BitNative: "Improved Signal To Noise
When writing code, we must strive to keep our signal to noise as high as possible. This aids in comprehension, speeds reading, and helps protect us from creating buggy code due to misunderstanding. Zombie code is directly opposed to comprehension. It slows reading and maintenance because less actual production code is on the screen at any given time. It’s visual noise because it’s unclear if one should read it at all. For some reason we often accept this compromise as developers, but we’d never accept such sloppiness in the real world. Imagine if the New York Times looked like this."

Readable programs - Luke Gorrie's blog

Readable programs - Luke Gorrie's blog: "Programming is, among other things, a kind of writing. One way to learn writing is to write, but in all other forms of writing, one also reads. We read examples - both good and bad - to facilitate learning. But how many programmers learn to write programs by reading programs? A few, but not many. And with the advent of terminals, things are getting worse, for the programmer may not even see his own program in a form suitable for reading. In the old days … programmers would while away the time by reading each others’ programs. Some even went so far as to read programs from the program library - which in those days was still a library in the old sense of the term.

OS X: Changing or resetting an account password

OS X: Changing or resetting an account password: "Start up from a Mac OS X Install disc (one whose version is closest to the version of Mac OS X installed).  Usually, you can start from the disc by putting it in your computer, restarting, and holding the C key. Or, put it in the computer and click the Install or Restore icon you see in the disc's main window (after which the computer will start from the disc without you needing to hold C). Or, you can use Startup Manager or the Startup Disk preference pane to select the Install disc.

AVL tree - Wikipedia, the free encyclopedia

AVL tree - Wikipedia, the free encyclopedia: "In computer science, an AVL tree is a self-balancing binary search tree, and it was the first such data structure to be invented.[1] In an AVL tree, the heights of the two child subtrees of any node differ by at most one; if at any time they differ by more than one, rebalancing is done to restore this property. Lookup, insertion, and deletion all take O(log n) time in both the average and worst cases, where n is the number of nodes in the tree prior to the operation. Insertions and deletions may require the tree to be rebalanced by one or more tree rotations."

Do more with Chrome Developer Tools

Do more with Chrome Developer Tools: The Chrome Developer Tools team recently launched new features and made several UI changes to improve your development and debugging workflow.

Develop for mobile 

Since we launched Chrome for Android, you’ve been able to use Chrome Developer Tools to debug and profile mobile web pages and web apps.

Today, we take this feature one step further by introducing device emulation support in Chrome Developer Tools. Device emulation includes, among other things, native User Agent and dimension overriding. This allows developers to debug mobile browsers on different devices and operating systems via the Settings Menu. So, now, you can emulate the exact device metrics of devices like the Galaxy Nexus and the iPhone to test your media query-driven design.

Chrome Developer Tools also supports single touch event emulation to make it easier to debug mobile applications on the desktop.

Profile rendering performance 

The Timeline’s Frame Mode feature now allows you to profile Chrome’s rendering performance, remove the jank and deliver the silky smooth performance users expect from your apps. To learn more about this topic, check out the recent "Jank Busters" video from Google I/O.



Preview your log items

The console now prints a user-friendly snapshot of the object properties taken at log time, whereas by expanding the object manually, you can still see its live content. This is especially useful when logging an object in a loop and observing its mutation. With this change, we resolved a longstanding bug many of you prioritized on crbug.com.



Play with experimental features

You can now try new experimental features in Chrome Developer Tools by visiting chrome:flags and enabling them there. Once you do that, a new tab called “Experiments” will be visible in the settings menu, allowing you to enable and use any of the following experiments:
  • Snippets (essentially multi-line console on steroids) 
  • Source mapping support for SASS 
  • Native memory profiling 
  • Geolocation / orientation override 
  • FileSystem inspection 
  • Canvas inspection 
  • CPU activity in Timeline 
  • CSS Regions support 
Some of these experimental features are almost ready while others have just landed and need some more refining. In either case, we’d love your feedback before we bake these fully in Chrome Developer Tools. You can also read our recently updated contribution guide if you’re interested in helping us make the tools better.

To get more information on all of Chrome Developer Tools features, check out our “Chrome Developer Tools Evolution” talk at the I/O 2012. You can also follow Google Chrome Developers on Google+ or @ChromiumDev on Twitter for more news on changes landing in Chrome Developer Tools.

One of the new HTML5 APIs that is slowly moving through the standardization process is the Web Audio API. With this API, currently only supported in Chrome, we get access to all kinds of interesting audio components you can use to create, modify and visualize sounds (such as the following spectrogram)."

The Flatiron School | SQL Joins Explained Visually: The 3 Ring Binder Model

The Flatiron School | SQL Joins Explained Visually: The 3 Ring Binder Model: "Any programmer worth their weight in bitcoins is going to need to know a bit about databases. If you’re not familiar with databases, you should take some time to read up on them, but hurry back, because for this post we’re going to be talking about the different kinds of JOINS. ‘Joins’ are a method of linking multiple tables in a database together so we can access values from them with a single query. Seems simple enough, but joins can be confusing. Since tables in a database aren’t tangible things, it can be difficult to understand the links we create between them. I for one find it difficult to really wrap my head around a concept until I can draw it, which made for some interesting moments in high school sex ed, but also led me to develop a method for visualizing how the different kinds of joins work! Let’s have a look:"

jq

jq: "jq is like sed for JSON data - you can use it to slice and filter and map and transform structured data with the same ease that sed, awk, grep and friends let you play with text.

jq is written in portable C, and it has zero runtime dependencies. You can download a single binary, scp it to a far away machine, and expect it to work.

jq can mangle the data format that you have into the one that you want with very little effort, and the program to do so is often shorter and simpler than you’d expect."

This Is Why They Call It a Weakly-Ordered CPU

This Is Why They Call It a Weakly-Ordered CPU: "On this blog, I’ve been rambling on about lock-free programming subjects such as acquire and release semantics and weakly-ordered CPUs. I’ve tried to make these subjects approachable and understandable, but at the end of the day, talk is cheap! Nothing drives the point home better than a concrete example.
If there’s one thing that characterizes a weakly-ordered CPU, it’s that one CPU core can read values from shared memory in a different order than another core wrote them. That’s what I’d like to demonstrate in this post using pure C++11."

Universal hashing - Wikipedia, the free encyclopedia

Universal hashing - Wikipedia, the free encyclopedia: "Using universal hashing (in a randomized algorithm or data structure) refers to selecting a hash function at random from a family of hash functions with a certain mathematical property (see definition below). This guarantees a low number of collisions in expectation, even if the data is chosen by an adversary. Many universal families are known (for hashing integers, vectors, strings), and their evaluation is often very efficient. Universal hashing has numerous uses in computer science, for example in implementations of hash tables, randomized algorithms, and cryptography."

orcaTalk

orcaTalk: "Orca Talk

The Northern Resident Orcas are a small population of killer whales living off the west coast of British Columbia. They make three main kinds of vocalizations, whistles, echolocation clicks and stereotyped pulsed calls. The land-based research station with OrcaLab has recorded over 20,000 hours of orca vocalizations, and in collaboration with them, we have digitized these and have made them available on the web on The Orchive. The calls that they make have been classified into different call types by scientists, and in this website, we have games to help you to learn these calls. We have a number of games for you to play, the first is Orca Talk, which teaches you the different calls of these unique individuals.

Typed Array Specification

Typed Array Specification: "This specification defines an ArrayBuffer type, representing a generic fixed-length binary buffer. It is not possible to manipulate the contents of an ArrayBuffer directly. Instead, a group of types are used to create views of the ArrayBuffer. For example, to access the buffer as an array of 32-bit signed integers, an Int32Array would be created that refers to the ArrayBuffer."

Code Review with Gerrit, a mostly visual guide

Code Review with Gerrit, a mostly visual guide: "A while ago, when Paul, Jason and I worked together, I became a big fan of code reviews before merging code. It was no surprise really, we were the first to adopt Git at the company and our workflow was quite ad-hoc, the need to federate knowledge within the group meant code reviews were a pretty big deal. At the time, we mostly did code reviews in person by way of "hey, what's this you're doing here?" or by literally sending patch emails with git-format-patch(1) to the team mailing list so all could participate in the discussion about what merits "good code" exhibited versus "less good code." Now that I've left that company and joined another one, I've found myself in another small-team situation, where my teammates place high value on code review. Fortunately this time around better tools exist, namely: Gerrit."

Radix sort - Wikipedia, the free encyclopedia

Radix sort - Wikipedia, the free encyclopedia: "Radix sort's efficiency is O(k·n) for n keys which have k or fewer digits. Sometimes k is presented as a constant, which would make radix sort better (for sufficiently large n) than the best comparison-based sorting algorithms, which are all O(n·log(n)). However, in general k cannot be considered a constant. In particular, under the common (but sometimes implicit) assumption that all keys are distinct, then k must be at least of the order of log(n), however other sorting methods become O(log (n) * log (n) * n) under similar constraints as they also need to step through an ever increasing number of symbols to do the comparisons."

CAP Twelve Years Later: How the "Rules" Have Changed

CAP Twelve Years Later: How the "Rules" Have Changed: "In its classic interpretation, the CAP theorem ignores latency, although in practice, latency and partitions are deeply related. Operationally, the essence of CAP takes place during a timeout, a period when the program must make a fundamental decision-the partition decision:

cancel the operation and thus decrease availability, or

proceed with the operation and thus risk inconsistency."

CAP Twelve Years Later: How the "Rules" Have Changed: "The CAP theorem states that any networked shared-data system can have at most two of three desirable properties:

consistency (C) equivalent to having a single up-to-date copy of the data;
high availability (A) of that data (for updates); and
tolerance to network partitions (P).

CAP theorem - Wikipedia, the free encyclopedia: "In theoretical computer science, the CAP theorem, also known as Brewer's theorem, states that it is impossible for a distributed computer system to simultaneously provide all three of the following guarantees:[1][2]
Consistency (all nodes see the same data at the same time)
Availability (a guarantee that every request receives a response about whether it was successful or failed)
Partition tolerance (the system continues to operate despite arbitrary message loss or failure of part of the system)"

The consensus problem is the problem of getting a set of nodes in a distributed system to agree on something – it might be a value, a course of action or a decision. Achieving consensus allows a distributed system to act as a single entity, with every individual node aware of and in agreement with the actions of the whole of the network."

CiteSeerX — Venti: A New Approach to Archival Storage

CiteSeerX — Venti: A New Approach to Archival Storage: "This paper describes a network storage system, called Venti, intended for archival data. In this system, a unique hash of a block's contents acts as the block identifier for read and write operations. This approach enforces a write-once policy, preventing accidental or malicious destruction of data. In addition, duplicate copies of a block can be coalesced, reducing the consumption of storage and simplifying the implementation of clients. Venti is a building block for constructing a variety of storage applications such as logical backup, physical backup, and snapshot file systems."

Cloudant Labs: On Google Spanner | Cloudant: "This past weekend Google released the latest in their seminal research publications -- Spanner. First introduced quietly nearly three years ago, Spanner is fully described, from motivation, to execution through operational performance data. The Spanner paper is technically revolutionary for a few reasons (described below), but most importantly it is continued proof that Google is a clear leader in distributed big data systems. In contrast to the original canon (GFS, MapReduce, Bigtable) and more recent replacements (Collosus, Percolator, Pregel, Dremel), I don't predict a Spanner clone will land as an Apache incubator anytime soon. The primary reason is that Spanner's largest design innovation leverages special hardware. Specifically one must install a coordinate network of GPS and atomic clocks in each participating datacenter."

At least, it won’t happen if you make a reasonable attempt to design a hash function using some knowledge of the search keys. Indeed, hashing is usually in the average case much closer to O(1). In practice, that means almost always you’ll find what you’re looking for on the first search attempt (and you will do very little secondary searching).

What it’s like to work for Stripe | Alex MacCaw: "IM & IRC

Google Chat and group IRC rooms are as integral as email to internal communication. Instead of meetings, we just do short chat conversations. Rather than constantly interrupt people’s train of thought, we prefer to communicate asynchronously. Chat is often the happy medium between the latency of email, and the bother of in-person interruptions.

That said, sometimes it is much better to discuss things face to face. If someone hasn’t got their headphones on, then it’s totally acceptable to come over and ask them for five minutes of their time when they can spare it.

Also, an IRC bot messages me every six hours or so asking me to optionally reply with brief description of whatever I’m working on. It then displays what I wrote on some of our dashboards. This is rather useful, as it gives visibility at a company wide level into what everyone’s doing."

Framing is one – the second request seems small, or even inconsequential, in scale compared to the first one.

efesx » Python directing C++: "The next logical step would then be a way to combine the benefits of such different programming languages in a single system. For instance, we could use C++ solely for the cpu-intensive parts, while the rest of the software could very well be written entirely in Python. The missing piece would then be a way to integrate the two. The common way of doing so is through SWIG, which is a tool that is able to wrap C++ to many different programming languages, Python included. Using SWIG right out of the box, we will be able to invoke C++ code directly from a Python interpreter. But what if we wanted to extend C++ classes in Python, making native C++ seamlessly call Python code?"

SourceForge.net: Faust : signal processing language:: "We have continued our experiments with Faust and web tools. With the help of Chris Rogers, developer at Google, we have integrated the Faust technology "natively" in the WebAudioAPI. Instead of using Faust to produce JavaScriptNode (hence the audio code of the JavaScriptNode is ultimately not very fast ...), we have developed a native Faust node. This node embed the Faust compiler as a library and the LLVM technology (http://llvm.org/) to generate very fast native code "on the fly." The chain is then:

DSP source code Faust ==> LLVM IR code (using the library board Faust and LLVM backend) ==> native code (using LLVM JIT embedded)

Faust nodes can then be inserted into a WebAudioAPI graph node like any other native node. They are of course much faster than the JavaScript version....
