Lighting up the XML Paper Specification [Proof-of-concept XPS reader for Silverlight!] Since getting involved with Silverlight and finding out the XPS document type WPF enables has XAML at its core, I 've been wondering how Silverlight wocould do as a lightweight XPS viewer. First, a bit of background: WPF is the Windows Presentation Foundation and represents a new approach to UI for Windows. XPS refers to the XML Paper Specification, a device-independent file format for flexible document repres

first parses the seed file to obtain the tracker address, and then connects to the tracker server. The tracker server responds to the download request and provides the IP addresses of other download recipients (including Publishers. The downloader connects to another Downloader. Based on the seed file, the two tell the other party that they already have blocks, and then exchange the data that the other par

As mentioned before (here), the downloader is a bottleneck when scrapy is running normally. In this case, you will see some requests in the scheduler, the number of concurrent requests in the downloader has reached the maximum, and the load of scraper (crawlers and pipeline) is lighter and the number of objects being processed Response does not always grow.There are three main settings to control the capaci

Scrapy engine is a central processor. It is connected to four modules: scheduler, downloadermiddleware (downloader middleware), spidermiddleware (Spider middleware), and item pipeline, communication between modules must be forwarded by the engine. First, scrapy engine distributes the seed URLs to each spider according to the domains of start_urls of spider. The Spider generates a request based on each URL to be captured and returns it to the engine, t
