The invention belongs to the technical field of computer software and data processing, and provides a differential upgrading method for a compressed file, which is divided into a differential stage and a reduction stage: the differential stage: decompressing an original compressed package of a starting version and an original compressed package of a target version; unifying and standardizing file permissions for the two decompressed folders, and modifying, accessing and changing timestamps; re-compressing to generate a first new compressed file and a second new compressed file with byte-level certainty; generating a first difference file based on the difference between the standardized directory structure and the content; comparing the second new compressed file with the original compressed file of the target version, performing lossless analysis on the ZIP metadata, and performing structured modeling on difference information to generate a second difference file; in the reduction stage, standardization, first differential reduction, recompression and second differential driven metadata accurate reconstruction are sequentially executed, and a result completely consistent with the byte level of the original compressed file of the target version is output. According to the method, the differential compression ratio and the restoration fidelity can be improved.

The present invention discloses a method for fast batch automatic downloading of high-throughput sequencing data, the method is based on snakemake language and MySQL database, and specifically includes the following steps: process triggering; capturing sample information in the process; uploading sample information to MySQL database; automatically downloading samples marked as wait in the database; modifying the sample status after the download starts in the database; synchronizing sample information to the MySQL database after the download is completed; modifying the database status of the downloaded sample; sending a summary email of the download; deleting sample data of completed projects. The method of the present invention can synchronize and download sample information in batches, and the whole process does not require human intervention, and can automatically trigger various links in the middle. During the processing process, the download summary information of the sample data will be automatically sent to the monitor in a timely manner to ensure that all operation steps can be traced, and the MySQL database is used to facilitate various information queries. The present invention also discloses a system and application for implementing the above method.

This invention provides a video download method, apparatus, electronic device, and readable storage medium. The method includes: in response to detecting that a first video downloaded by a client is interrupted due to transcoding on the server side, obtaining the download progress of the first video already downloaded by the client; the download progress is used to indicate the amount of data downloaded and is associated with the identification information of the last downloaded video frame; based on the download progress, determining a set of segmented videos to be downloaded from a second video generated after transcoding the first video, and downloading the set of segmented videos; matching the last downloaded video frame of the first video with the video frame content of the second video to determine the mapping time point corresponding to the last video frame in the second video; in response to playing to the last video frame of the first video, resuming playback of the second video from the mapping time point.

The invention discloses a skin changing method, system and device for an application program, a storage medium and electronic equipment, and the method comprises the steps: receiving an interface display instruction, and determining whether theme color configuration information of the application program is locally stored or not; under the condition that the theme color configuration information is locally stored, on the basis of the theme color configuration information, updating the color in the target interface requested to be displayed by the interface display instruction; and displaying the target interface after the color is updated. Since the color of the target interface is directly updated by adopting the locally stored theme color configuration information, the speed of updating the color of the target interface by utilizing the theme color configuration information is high, the situation that the whole target interface is replaced by re-downloading a skin file is avoided, the flow and the downloading time are saved, and the user experience is improved. Meanwhile, the effect can be taken after the color of the target interface is updated, restarting of the application program is avoided, and therefore the skin changing efficiency is improved.

The invention relates to a multi-thread whole vehicle OTA high-speed downloading method and device, and the method comprises the steps: segmenting an OTA upgrade package into a plurality of data blocks, and storing the data blocks in an OTA cloud server; in combination with a P2P network, a plurality of data blocks are downloaded in parallel through a plurality of threads, one process is always connected with an OTA cloud server, other processes are connected with P2P network nodes, and the priority of the process connected with the OTA cloud server is the highest. According to the method, the downloading speed of the whole vehicle OTA is remarkably increased, the upgrading time is shortened, the burden of the central server is relieved through the P2P technology, the expandability of the system is improved, and the downloading stability and reliability are enhanced through a breakpoint resume mechanism.

The application provides a decentralized downloading method for sharing large files, which comprises the following steps: deploying a Transmission software in a server and each user terminal, generating a seed file for a to-be-downloaded file by using the software in the server; virtually dividing the to-be-downloaded file into virtual blocks with equal sizes, and writing index information and Hash verification codes of each virtual block into the seed file; accessing the server by the user terminal, and parsing the seed file by using the Transmission software of each user terminal to obtain the index information and Hash verification codes, download corresponding file segments from the to-be-downloaded file, and generate seed segment files for the file segments; and accessing other user terminals by the user terminal, parsing the seed segment files of the other user terminals by using the Transmission software of the user terminal, and downloading corresponding file segments. The application expands the uploaders from only the server to the user terminals, that is, the user terminals are downloaders and uploaders at the same time, and realizes the decentralization of downloading.
