It should be noted that the multi antenna rate terminal described below also needs to be supported.802.11b (released in 1997WIFI 1）2.4 GHz, maximum rate 11 Mbps (using DSSS modulation mode)802.11a (released in 1999WIFI 2）5GHz, maximum rate 54Mbps (using OFDM modulation)Introduce 5GHz frequency band to reduce interference.However, due to its cost performance and other reasons, we have not seen any support from household equipment.It is mainly used for medical equipment, network bridge, enterprise network, high-density environment and other professional equipment.802.11g (developed in 2003
DongleOverview of FIDO, U-Shield and tax control panelWe have basically seen all kinds of verification tools in our lives, such as software dongles, online banking U shields, financial tax control disks, authentication Ukey, electronic signature Ukey, and so on.However, they all use customized or proprietary APIs for interconnection.Although the USB Server scheme can be used to switch freely, it would be great if there was a chance to unify.Now, naturally, Zhang will first talk about the previously complex and single function verification tools, and then talk about the standardized FIDO.Of course, due to its own non related industry practitioners, there may be omissions
Introduction to foob ar2000Foob ar2000 is an advanced free audio player for Windows platform.http://www.foobar2000.org/downloadDifference of foob ar2000 output modeFoob ar2000 uses DS output by default, because DS output has good compatibility with all sound cards.As long as the system can make sound, it can make sound. Based on this, it does not need any plug-ins.DS（DirectSound）The default output mode is also the mechanism that we usually use Windows system to make voice.The output feature is that the sound can be output after secondary modulation by the system, such as
Zhang Ziran kindly reminded that when compiling under small memory vps or low performance embedded devices, it is recommended to copy and execute commands line by line.Although the execution of multi line replication will be automatically segmented, it may still cause vps to be suspended (possibly due to network and other reasons).Install the compilation environment required for configuring nginx or modules.Installation and compilation environment of ububtu/debian related systemsapt-get -y install build-essential libtoolRed hat/Centos related system installation and compilation environmentyum -y install automake autoconf libtool make gcc gcc-c++Common nginx
Zhang Ziran has bought a pogoplug and has been idle for almost 6 years, but has never had time to struggle.A few days ago, I suddenly remembered that the official website of pogoplug could not be opened.Its feature is that it supports the sata interface and the gigabit network interface, and the motherboard boots from the sata interface by default.These are what many cheap motherboards don't have.Introduction to pogoplugOrigin of pogoplugPogoplug became popular in China because the video compression module of the pogoplug video version overheated and caused a fire. The official announced that all of them were recalled.After the video compression module was dismantled in Hong Kong, it was processed at a low price. After being bought by Qingzhou Xiaoxiong and other businesses, it was sold on Taobao
The difference between eID and CTID of the Ministry of Public SecurityWhether it is CTID or eID, there is no relevant laws and regulations to support it at the pilot stage and it is not mandatory to use it.The purpose of this article is only for individuals to learn the national network authentication technology. Do not chase across provinces unless you judge whether it is good or bad (manual funny).EID was born in the Third Research Institute of the Ministry of Public Security, based on hardware verification such as non-contact chips and sim cards.It also focuses on privacy protection. In addition, the current eID actually includes the two-dimensional code verification function of CTID (Tencent e-Cernet applet).EID QR code (including eID0001123345678901231224141
It should be reminded that K3c uses nand48 pin flash, and Zhang Ziran suggests careful operation.Take responsibility for all consequences.It is emphasized that the reason for the 48 feet is that the non related employees generally have no tools or cannot weld well at all.Moreover, the corresponding programmer is not cheap compared with the router, and it is basically useless when playing with bricks.(Of course, I can play. For example, the big guys who use hg255d as a programmer, just ignore this.)Basic parameters and hardware information of Fijian K3cUnpacking Feixun K3cAfter the network cable is connected normally and the IP address is obtained, access the 192.168.2.1 or p.to (dns non routing cannot be used) configuration password and other information.Dismantle the machine
