Every day, there will be a lot of hype about new languages and databases. But what technologies are actually used? Will the technologies used by good start-ups be different from those used by poor ones?
Angellist's self-report can reveal some of our answers. You can find that mongohood uses python, Django, and iOS, and secret uses Java, go, Python, JavaScript, HTML5, CSS, IOS, and Android.

4. Comparison of performance of existing distributed Technologies
1: Socket vs remoting
Using socket is undoubtedly the most efficient. However, in a complex interface environment, the socket development efficiency is also the lowest. Therefore, with both development efficiency, remoting can be used instead of socket development. And:1. The remoting speed of the TCP channel is very fast.You can use the port viewing tool to find
Broadband access technology is still quite common, so I have studied the two new broadband access technologies that are currently emerging. I would like to share them with you here and hope they will be useful to you. In the past decade, two new modulation and demodulation technologies, Cable Modem and ADSL Asymmetric Digital user line, have emerged. Cable Modem implements data transmission up to 10 mbH/s o
I. Introduction (basic concept)Basic concepts and techniques used in web development:A -ajaxAJAX is all called "Asynchronous JavaScript and XML" (Asynchronous JavaScript and XML) and is a web development technique for creating interactive Web applications. According to Ajax author Jesse James Garrett suggested that Ajax:Use XHTML + CSS to represent information;Use JavaScript to manipulate the DOM (Document Object Model) for dynamic display and interaction;Using XML and XSLT for data exchange and
I. Introduction of the ContentJava EE's 13 core technologies: JDBC, JNDI, EJB, RMI, JSP, Java Servlet, XML, JMS, Java IDL, JTS, JTA, JavaMail, and JAF.Java was initially in the browser and client machines, when many questioned whether it was suitable for server-side development. Now with the increase in support for third-party Java EE, Java is widely accepted as one of the preferred platforms for developing enterprise-Class Server-side solutions.The J
Ajax
xml-based asynchronous JavaScript, referred to as Ajax, is a crown in the current web innovation (called Web2.0). Thanks to the various technologies that make up Ajax, Web application interactions such as Flickr, backpack and Google have made a qualitative leap in this area. The term derives from a description of the conversion from web-based Web applications to data-based applications. In a data-based application, the user needs data such as a c
: This article mainly introduces the principles and methods for excellent programmers to think about and learn new technologies. if you are interested in PHP tutorials, please refer to them. I recently learned about several MVC PHP frameworks, two of which are in the company. It is found that these things are similar, from processing logic to page rendering; from service to layout; Configuration Implementation is nothing more than XML, or annotation .

Think about what would happen if you are unemployed and have no job now,Think about it now there are so many brethren who are traveling around to find a job.Think about what if your company suddenly wants to turn technology in order to seize the market?Think about how you want to change the technology field for your future. What should you do? Or you are not satisfied with your current knowledge structure and want to enrich it, but you do not kn

IntroducedIn this article, we will learn about the concept of JSON and how JavaScript interacts with some of Microsoft's technologies such as ASP. NET MVC, ASP. NET Web Forms, WCF, and Web APIs.What is JavaScript object? JavaScript contains two kinds of things: variables and functions. Variables store data, and functions are responsible for performing specific actio
Last week we discussed overestimated security technologies. This week we will focus on the other side of the coin. The following are technologies widely underestimated in the security industry today. Because some security professionals think that amazing tools may seem to be a waste of budget, it is not surprising that a technology appears on both overestimating and underestimating lists.

Learning new technologies can improve a person's learning ability and adaptability. It is self-evident for the importance of IT people. So, have you mastered a set of learning methods that are suitable for you? People are always too impulsive. I have heard of a new technology, and I have learned how to find a book and click the keyboard. Is there a more agile way to learn new
Logistics is a hot topic at present. Whether in the transformation of existing enterprises or in emerging industries, logistics management has become a way to improve efficiency and reduce costs. The importance of logistics was actually known two thousand years ago, but in the past it was called a logistics supply problem or a grain supply problem. This problem was once one of the core factors affecting the success or failure of the ancient war. The importance of logistics has never been reduced
With the continuous development of the Communication Industry, broadband access technology is constantly being innovated. Here we will introduce two new access technologies and make a detailed comparison, I believe that the access industry will develop better in the future.
In the past decade, two new modulation and demodulation technologies, Cable Modem and ADSL Asymmetric Digital user line, have emerged.
In the previous article, "Introduction to various wireless WLAN Access Technologies", we introduced the overview of wireless WLAN Access Technologies and six Wireless Access Technologies, below we will complete up other types of wireless WLAN access technology. We are familiar with these technologies.

Three technologies for optimizing the data center network based on content
Network technology can be divided into multiple layers, from the physical link layer to the application layer. Different layers run different protocols and have different functions. With the development of data centers, network technology has been greatly improved, and networks have penetrated into every corner of the world. However, when we access the Internet, we often encou
Implementation principles and key technologies of VOIP: basic principles and implementation forms IP telephone systems convert analog signals of common telephones into IP data packets sent by computers over the Internet, at the same time, it also converts the received IP packet into a sound analog electrical signal. After the conversion and compression of the IP Phone System, the transmission rate of each common phone is approximately 8-11 kbit/s band
