Leonardo da Vinci: Daily Routine

Written by kal1sha

Few people know that Leonardo da Vinci invented a way to spend little time for sleep, but not suffer from doing so. He slept only an hour and a half per day! Many people say that it was the exact secret of his efficiency. Today it is called a polyphasic sleep. Genius Leonardo decided that he spent too much time on sleep and invented his own sleep method. It lies in sleeping for 15 minutes every 4 hours. And he lived like that during not a week, but many years. Why does it work? Psychologists say that after sleep our working capacity increases from 6 to 10 times as much. And wise Leonardo used it to the fullest extent. Other psychologists say that polyphasic sleep doesn’t match all the people and they should read the literature about: sleep nature relaxation eutrophy healthy living P.S. I think this sleep method will

Yogurt making machine powered by Arduino

Written by Shrim

Everyone knows that yogurt is a very better-for-you product, plus it’s delicious. There is a short story under the cut about how I decided to create a yogurt maker, some pictures and a sketch. Wandering in the vast expanses of the Internet I came across such an interesting thing as a yogurt maker. My wife likes yogurt and fairly often buys it. Having read the specialized website, I was inspired. I was inspired by the very thought of easily making yogurt at home, plus it will be more health-giving than the store-brought one. Having read a few reviews and comparisons, my wife and I decided to buy “Moulinex YG230 YOGURTEO”. But oops, we couldn’t find where to buy it in our town. We were just going to place an order when it dawned upon me. What is a yogurt maker? Roughly speaking, it’s a device for keeping some definite temperature

LibreSSL: clean version of OpenSSL (OpenBSD project)

Written by Kukuruku Hub

Participants of the OpenBSD project, that have developed the system of the same name and also different tools such as OpenSSH, OpenBGPD, OpenNTPD and OpenSMTPD, began a LibreSSL project. It is a cleared from odd codes, easier version of OpenSSL. Theo de Raadt, the founder and the manager of OpenBSD and OpenSSH projects said that they have managed to get rid of approximately 90 000 code lines at C and 150 000 lines of the content on the whole. MacOS, Netware, OS/2, VMS and Windows support is deleted as few people need it. ”We are trying to make code more clean. 99.99% community representatives don’t need VMS support and 98% don’t need Windows support, — says Theo de Raadt. – They need POSIX support so that Unix and Unix-derivatives could start. People don’t care about FIPS. Code should be simple. Even after all the changes, the code base is still

Marionette.js. Drag&Drop model sorting in the collection

Written by pharrell

Swapping elements in a list is a common task. But as a rule it is often made in a thorny way, especially if it’s Drag&Drop. And now I am going to tell you about a very easy and flexible way to do it using Marionette.js and jQuery UI Sortable. Installing jQuery UI We will need Sortable part only, so in order to save the traffic, I unchecked all the ticks for you here . You just need to download it. Pay attention We are using a reference to Marionette in the code below: var Marionette = Backbone.Marionette; Creating Behavior template with Marionette.Js This functionality will be implemented with Behaviors. Here’s the behavior code that will be responsible for sorting models inside the collection: Behaviors.Sortable=Marionette.Behavior.extend({ onRender:function(){ var collection=this.view.collection // Close the collection ,items=this.view.children._views // Get the list of child elements ,view ; for(var v in items){ view=items[v] // Hook the

At Stanford University a paper microscope has been developed that costs less than a dollar

Written by ilya42

The main motive for the creation of the microscope was the struggle against malaria — in the developing countries about a billion microscopic examinations of the blood samples per year have to be carried out for malaria diagnosis. A standard laboratory microscope is an expensive and fragile device. Stanford scientists have managed to construct a microscope with magnification up to the 2000x, while the cost of all the components in a mass production will be 97 cents. The microscope body is cut out and folded from a sheet of thick paper. Other components are a flat battery, a LED switch, a piece of conductive copper tape and a glass or a sapphire ball lens. Paper microscope fits easily in your one's pocket, weighs less than ten grams, can be used for brightfield, darkfield, polarized and fluorescent microscopy, and even work as a projector. One battery lasts for 50 hours.

Written by Stephan Ronald

DBX to PST conversion is the best technique to migrate emails from Outlook express to Microsoft Outlook 2013, 2010, 2007 and 2003 etc. In this article I will explain a safe and suitable method to perform the conversion. Outlook Express being an outdated email application is not used amongst users but those who are using wanted to migrate to MS Outlook to avail advance set of features and compatibility. Users who are seeking migration from OE to Microsoft Outlook needs to first convert DBX items in PST file importable in MS Outlook. This is because MS Outlook does not understand DBX format to read files, users are required to convert DBX in PST to allow Outlook reads its mailbox items. For such concerns only third party tools like DBX to PST converter are used as there is no manual procedure available to import Outlook Express in MS Outlook. How
