The core solution to prevent multi-image oom is to use LRUCache technology, but LRUCache only manages the storage and release of images in memory, and if the images are removed from memory, it is obviously time-consuming to reload them from the network. So Google offers a solution for hard disk caching: Disklrucache (not officially written by Google, but officially certified). In general, news apps are stored in the local cache after they get the data

A traditional LAN switch is a L2 network device that constantly collects information during operations to create a MAC address table. Layer-3 switching is also called multi-layer switching technology or IP address switching technology. In today's

[Peer-to-peer technology] Front-end technology-how to reconstruct, build a blog, and learn how to develop automation. In the article "Summary of first-to-second reading materials from the front-end to the great god", I introduced in depth the front-end beginners and advanced technical materials, today, xiaobian continues to publish five dry articles on front-end learning. Let's take a look! In addition, en

UWP hand-drawn video creation tool technology sharing series, uwp tool technology The final product of hand-drawn videos is video files. The previous articles mainly focus on the creation of hand-drawn videos. Today we will talk about the export of hand-drawn videos. This article mainly uses UWP as an example. In addition, we will introduce some Web-side problems and solutions. As mentioned above, after a h

In the previous article, we will introduce anti-simulation technologies commonly used by malware to readers. In this article, we will introduce various anti-Debugging techniques used by malware to impede reverse engineering, so as to help readers better understand these technologies, this enables more effective dynamic detection and analysis of malware. I. Anti-debugging technology Anti-debugging is a common anti-detection technique, because malware a

1. What is Java IDL? ---- Java IDL (Interface Definition Language) can realize the interaction between objects on different platforms on the network. This technology is based on the description of the Common Object Request proxy architecture (CORBA) specification. IDL is an interface definition language that does not depend on a language. All languages that support CORBA have the IDL ing of IDL to this language. As its name indicates, Java IDL support

I recently applied the Java RMI technology, so I will summarize the use of RMI. In addition, the implementation of EJB is also based on Java RMI. RMI remote method calls can be called across machines through the network, but Java RMI only supports Java programs on both sides. To achieve completely heterogeneous on both sides, you need to use the legendary web service. Two or more projects should be established to ensure good results. Of course, if you

According to the reporter's understanding, at present, the only professional Mesh-Wifi equipment manufacturer in China -- Shanghai huichuang communication (GBCOM), in its MESH network, uses the multi-hop feature, A non-conventional seamless coverage technology-MESH terminal relay was developed. Multi-hop refers to the use of a terminal as a relay in the tr

this gets the approximate time required to complete the project. HoweverIn fact, each project encountered a two or three bottleneck during the development process. These bottlenecks can take a lot of the programmer's time, and you won't be able to foresee them before you meet them. They stall the whole project, causing the schedule to be delayed for weeks or even months. These are inexperienced people who do not understand the complexity of the assessment. They don't understand how it's going t
