1. Introduction to ADSL
Although it is common to connect to a vro network, we sometimes need to use PPPoE to directly connect to the ADSL (or DSL) modem.
Of course, you must first pay for the network operators of China Netcom or China Telecom to connect the lines. The "DSL" on the modem is on, which generally indicates that your line is smooth.
You must have the username and password of your account. A sui
.
2. the semantics of each expression must be well defined so that users can create models that others understand. Tools can generate legal implementations from models, metadata captured from the model can be used to process tasks as expected, such as configuring servers.
Languages that meet these standards are called domain-specific language (DSL) and should be modeled for those special domain concepts. DSL
This guide will help you establish an ADSL network connection with the PPPoE Ethernet modem under Ubuntu 6.06 LTS (Dapper Drake).
1. Introduction
Although networking with routers is common, we sometimes need to use PPPoE directly to connect to ADSL (sometimes called DSL) modem.
Of course, first of all you have to pay a good money to netcom or telecommunications network operators, the line to connect well. Modem on the "
The previous issue of this series describes how to use a specific domain language (DSL) to capture domain idiomatic patterns. This issue will continue with this topic to showcase various DSL build methods.
In the next book, in Domain specific Languages, Martin Fowler will explain the difference between the two DSLs. External DSLs can build a new syntax that requires tools such as Lexx and Yacc or ANTLR to
Domain-specific languages have become a hot topic; Many functional languages are popular, mainly because they can be used to build domain-specific languages. For this reason, in the 8th article in the Scala Guide series for Java™ developers, Ted Neward to build a simple calculator DSL to demonstrate the power of building an "external" DSL for functional languages. He examines a new feature of Scala: Case cl
Before we talked about the Elasticsearch (search engine) operation, such as: Add, delete, change, check and other operations are used Elasticsearch language commands, like SQL command, of course Elasticsearch Official also provides a python operation Elasticsearch (search engine) interface package, just like the SQLAlchemy Operation database ORM box, so that we operate elasticsearch do not have to write commands, Use the Elasticsearch-dsl-py module to
problem is the readability of the code. It is not easy to immediately see what this code wants to achieve, so it needs to be carefully checked for omission or not being strictly in line with the requirements. When requirements change, it is desirable to know exactly where the code needs to be modified and, as a modification, to be confident that it will not affect other functions. Meta-programming concepts are used to solve this problem.Pragmatic Programmer (pragmatic programmer?) The meta-prog

In this column last month, I covered an example of using a specific domain language (DSL), defined in your code as a common design practice. (I introduced the concept of idiomatic patterns in the "combining methods and SLAP" article.) DSL is a good medium for capturing patterns because they are declarative, easier to read than "normal" source code, and make your capture patterns stand out from the surroundi
Introduction: Ward Cunningham once said that clean code clearly expresses what the code writer wants to express, while graceful code goes further, and beautiful code looks like it is specifically for the problem to be solved. In this article, we will show the design and implementation of a modular parser, the final code is graceful and extensible, as if it were to parse a particular syntax. We will also select an example in the H.248 protocol to implement its parser using the combined parser des
