Lionheart is designed for cruising as well as racing, and is therefore built to MCA. No expense has been spared to ensure that she is competitive on the race course, and her performance has been optimised by a design that incorporates research done on previous J-class yachts. Lionheart’s hull is built in high tensile Alustar plating and extrusion materials, and she employs longitudinal stringers to ensure maximum stiffness. Tremendous 17-metre overhangs lend Lionheart a striking appearance. She features two deckhouses and two cockpits, with one of each reserved for the owner, and the owners’ cockpit linked to their suite for maximum privacy.

What is the best video codec for game recording, video recording, and screen recording? If you use a high-compression codec, you can get a small video file, but the encoding speed might be slower. If you use a high-quality codec, you can get the best quality video, but the video file size might be larger. If you use a high-speed codec, you can reduce CPU usage, but the video file size might be larger. So, you have to choose the best video codec by yourself to meet your recording needs.

The hydro generation or “creating energy while sailing” function is an automatic feature in all Oceanvolt motors. This feature is activated by pushing the button on the Oceanvolt displays for 5 seconds. The display will automatically switch to regeneration mode showing the current generated power, RPM and time until the batteries are fully charged. With a normal folding propeller the motor kicks the blades out and centrifugal force combined with the motor controller keep the blades open. The motor controllers tune the system actively at 10 Hz which prevents the blades from closing (too much braking would close the propellers). This is continuous monitoring, the system will adjust the propeller RPM depending on the boat speed.

jQuery and its cousins are great, and by all means use them if it makes it easier to develop your application. If you're developing a library on the other hand, please take a moment to consider if you actually need jQuery as a dependency. Maybe you can include a few lines of utility code, and forgo the requirement. If you're only targeting more modern browsers, you might not need anything more than what the browser ships with. At the very least, make sure you know what jQuery is doing for you, and what it's not. Some developers believe that jQuery is protecting us from a great demon of browser incompatibility when, in truth, post-IE8, browsers are pretty easy to deal with on their own.

Did you know that you don't have to link to an external image file when using an <img> element in HTML, or declaring a background-image in CSS? You can embed the image data directly into the document with data URIs. Basically, a super long string of gibberish characters. It's not gibberish to the browser though of course. This data is interpreted as the type of file you are saying it is.

Digital signatures are used world wide to verify the authenticity of messages and confirm that they have not been altered in transmission. The Digital Signature Algorithm (DSA) is a Digital Signature Standard for the Federal Information Processing Standard and uses public key cryptography. The Elliptic Curve Digital Signature Algorithm (ECDSA) is a version of DSA using elliptic curves. In this paper, I will introduce ECDSA and discuss its key generation, signing, and verifying procedures. Then, I will compare this algorithm to the RSA digital signature algorithm and discuss its various advantages and drawbacks. Finally, I will discuss the security of ECDSA and attacks that can break it.

NaCl (pronounced "salt") is a new easy-to-use high-speed software library for network communication, encryption, decryption, signatures, etc. NaCl's goal is to provide all of the core operations needed to build higher-level cryptographic tools.
Of course, other libraries already exist for these core operations. NaCl advances the state of the art by improving security, by improving usability, and by improving speed. The following report contrasts NaCl with other libraries from a security perspective: (PDF) Daniel J. Bernstein, Tanja Lange, Peter Schwabe, "The security impact of a new cryptographic library". Pages 159–176 in Proceedings of LatinCrypt 2012, edited by Alejandro Hevia and Gregory Neven, Lecture Notes in Computer Science 7533, Springer, 2012. ISBN 978-3-642-33480-1. The following report was created for Research Plaza and gives an introduction to NaCl for a wider audience: (PDF)

This paper introduces a new cryptographic library, NaCl, and explains how the design and implementation of the library avoid various types of cryptographic disasters suffered by previous cryptographic libraries such as OpenSSL. Specifically, this paper analyzes the security impact of the following NaCl features: no data flow from secrets to load addresses; no data flow from secrets to branch conditions; no padding oracles; centralizing randomness; avoiding unnecessary randomness; extremely high speed; and cryptographic primitives chosen conservatively in light of the cryptanalytic literature.

Damn Small Linux is a very versatile 50MB mini desktop oriented Linux distribution. Damn Small is small enough and smart enough to do the following things: Boot from a business card CD as a live linux distribution (LiveCD), Boot from a USB pen drive, Boot from within a host operating system (that's right, it can run *inside* Windows), Run very nicely from an IDE Compact Flash drive via a method we call "frugal install", Transform into a Debian OS with a traditional hard drive install, Run light enough to power a 486DX with 16MB of Ram, Run fully in RAM with as little as 128MB (you will be amazed at how fast your computer can be!), Modularly grow -- DSL is highly extendable without the need to customize

I have Server A and Server B which exchanges some data. Server A on user request pull data from Server B using simple file_get_content with some params, so server B can do all task(database etc) and return results to A which formats and show to user. Everything is in PHP. Now I am interested what is fastest way to to this? I made some test and average transfer time for average response from server B at (~0.2 sec). In that 0.2 sec, 0.1 sec. aprox. is Server B operational time (pulling data calling few databases etc) what mean that average transfer time for 50kb with is 0.1 sec. (servers are NOT in same network) Should I try with: 1.cURL insted of file_get_content ? 2.Or to try to make whole thing with sockets( I never work work with sockets in PHP but I supose that easily can be done, on that way to skip web server )? 3.or something third?

If you receive warnings that your virtual memory is low, you'll need to increase the minimum size of your paging file. Windows sets the initial minimum size of the paging file equal to the amount of random access memory (RAM) installed on your computer, and the maximum size equal to three times the amount of RAM installed on your computer. If you see warnings at these recommended levels, then increase the minimum and maximum sizes.
