We should have seen a discount promotion for Virpus merchants to launch SSD Linux/Windows VPS hosts in the summer last weekend. The user reputation of Virpus merchants was not very good before it was acquired, and does not support the refund policy. However, in order to experience its stability and performance, the old Left has bought a Linux ssd vps with 12.75 MB of memory for the Seattle data center for t

The advent of solid-state drives, just let the computer really into the rapid development of the era, the previous computer no matter how good configuration is always mechanical hard drive drag, because slow speed lead to low performance, startup software, etc., now has a solid state disk when the system disk and cache disk, you can solve this problem slightly. The difference between solid-state hard drives and ordinary hard drives: solid-state drives are the last of the five major computer har

The upgrade cost reached $45000000 and was the biggest transformation investment since Linode was founded (11). SSD StorageThe SSD array storage system used in Linode is not a popular hybrid hard disk at present, and it uses the server-level SSD hard disk with battery back-up power. The price is very expensive. 40Gbps NetworkEach Linode host server uses a Gbps

Because of work, sometimes two computers are needed to work, and most people engaged in development are those pursuing computer performance, so the laptop is naturally not light, not to mention the two. I have been suffering from two computers for more than half a year, and finally made up my mind to install a system into a mobile SSD, carrying a non-hard drive computer and adding two mobile SSDS to reduce the burden. After one day's exploration, many

Linux SSD optimization policy 1. do not use a file system with logs. If you have the ability, consider a file system that supports ssd, such as ubifs. If not, use ext2 www.2cto.com 2. disable noatime nodiratime of the file system, because the access time will increase ssd write, there is no need to modify/etc/fstab, for example, change/dev/hda9/data ext2 defaults

Considering many algorithms including YOLO SSD, this series of onestage methods can not solve the problem of small target detection, after thinking that the problem is different from the feature map and the big target of small target.A paper solves this problem, that is, the RSSD algorithm R is the meaning of the rainbow means that multiple feature maps are fused as a classification standard.Paper: Enhancement of
