Unix-like operating systems commonly implement IP address blocking using a TCP wrapper, configured by host access control files /etc/hosts.deny and /etc/hosts.allow.. Both companies and schools offering remote user access use Linux programs such as DenyHosts or Fail2ban for protection from unauthorized access while allowing permitted remote access.
Classical (algebraic) block codes and convolutional codes are frequently combined in concatenated coding schemes in which a short constraint-length Viterbi-decoded convolutional code does most of the work and a block code (usually Reed–Solomon) with larger symbol size and block length "mops up" any errors made by the convolutional decoder ...
Limiting the speed of data sent by a data originator (a client computer or a server computer) is much more efficient than limiting the speed in an intermediate network device between client and server because while in the first case usually no network packets are lost, in the second case network packets can be lost / discarded whenever ingoing data speed overcomes the bandwidth limit or the ...
Note: 192.0.2.0/24 is not actually a sensitive address. It is included in this list for testing and training purposes and may safely be blocked with no requirement to notify the WMF. Other private network addresses (127.0.0.1, 10.0.0.0/8, 192.168.0.0/16, 172.16.0.0/12) are sometimes used by Wikimedia infrastructure, sometimes intentionally ...
Excel's storage of numbers in binary format also affects its accuracy. [3] To illustrate, the lower figure tabulates the simple addition 1 + x − 1 for several values of x. All the values of x begin at the 15 th decimal, so Excel must take them into account. Before calculating the sum 1 + x, Excel first approximates x as a binary number

If you have never edited Wikipedia before and/or do not have an account, you may need to create one. This will normally allow you to edit despite the block on your IP address. If you are currently blocked from creating an account, and cannot create one elsewhere in the foreseeable future, consider requesting one at Wikipedia:Request an account.
