Simplifying complexity: Thirty years of change in IBM’s sales organization

IBM has announced a simplification of the organization of its sales force, hoping to make it easier for customers to deal with by reducing the number of sales groups to two from more than 50, the Wall Street Journal reported. The main driver of this organizational shift is IBM’s overall shift to hybrid cloud business strategy. During the past five to ten years, the enterprise IT industry has been fully transformed to cloud. The growth of IBM, once the industry leader, has slowed down. The growth of cloud business lags behind Microsoft and Amazon, and the growth of IT service business lags behind accenture and other competitors.

How much money can you make running a Courier post?

The boss said that the pork was expensive and the price increased. The clothing store on the first floor of the nearby shopping mall was all changed. Those unknown brands were all withdrawn, and the new ones were all powerful chain brands. Under the double blow of e-commerce and the epidemic, it is really too difficult to be a self-employed owner of a physical store. Now, community group buying has begun to grab the business of selling vegetables. In the future, physical stores may gradually become a subsidiary of e-commerce, as illustrated by the increasing number of roadside Tmall and JINGdong stores. In the past two years, I have also witnessed the rise of a new offline business dependent on e-commerce, namely express delivery stations.

How to draw a good architecture diagram

When we want to describe our system with one or more pictures, are there many times when we don’t know what to do with the canvas, delete and come again? I want to describe my system in one diagram, but I want the product, operation, and development to understand? Even half-drawn without knowing who the audience is? Is the drawing a product drawing a functional drawing or a technical drawing or a hodgepodge? There are a few boxes on the drawing. Do you want to find some boxes to put in? How to draw the layout is not satisfied… If you are confused, this article will introduce a drawing methodology to make architecture diagrams clearer.

Analysis of AQS principles and applications

AQS, namely juc and AbstractQueuedSynchronizer under the contract, we might as well be called the abstract queue synchronizer. Implementing a queue-based blocking lock and associated synchronizers, AQS can be used as a benchmark for synchronizers representing state in a single int variable. Familiar concurrency tools such as ReentrantLock, ReentrantReadWriteLock, Semaphore, and CountDownLatch are all implemented based on AQS. AQS defines some common API methods related to synchronization, and reserves some protect methods for subclasses to implement (subclasses must implement as long as they use), AQS is not responsible for state change maintenance and synchronization mechanism, for different subclasses of implementation, its state quantity represents different meaning. Subclasses implement synchronization mechanisms such as atomic change state and block release by implementing the Protect method.

Swastika photos | UML start guide

When it comes to the analysis and design of object-oriented technology, UML is indispensable. Many of my programmer friends are familiar with the concept of UML and use it in their work, but some of my programmer friends are actually not good at using UML or even have some ambiguity about it, including myself. Therefore, I hope to combine my own experience and practice, write a UML introduction article, to help object-oriented programmer friends can better use it, so as to successfully complete their own programming design work.
