Junyao Ye, also known as Jarrett Ye is the author of the new stochastic model of spaced repetition
“It’s a substantial extension of my previous conference paper A Stochastic Shortest Path Algorithm for Optimizing Spaced Repetition Scheduling. FSRS is based on the model proposed in that paper.”
Due to the following issues according to Glen Barber, the Release Engineering Lead of the FreeBSD Project:
1) freebsd-update(8) has previously failed to upgrade from 13.x and Β Β earlier due to a file name that had been replaced with a directory of Β Β the same name.Β A patch for this is under testing. 2) FreeBSD arm64/aarch64 EC2 AMIs have been failing to build properly, Β Β presumably due to lang/rust build failures leading to the ec2-scripts Β Β package from being prevented to be available.Β The last 15.0-CURRENT Β Β snapshots seem to have this resolved, so hopefully it is also Β Β resolved for what will eventually be the ‘release_0’ package set for Β Β 14.0-RELEASE, but that is still over a week away. 3) There are no “official” FreeBSD base packages available.Β I have been Β Β occupied with external factors preventing me from having cycles Β Β available to look into this without interruption, but I think I am Β Β going to err on the side of caution and have a manual package set run Β Β available via https://download.freebsd.org/ somewhere within the Β Β version, architecture, and machine type namespace. 4) Vagrant images fail to upload due to an incorrect target following Β Β the addition of ZFS images.Β This is another issue where I have Β Β personally been blocked/blocking progress. 5) The ‘ftp-stage’ target does not currently account for ZFS virtual Β Β machine images.Β I again have this in my queue.Β I do not know if Β Β I necessarily care too much about this for 14.0-RELEASE, since all Β Β virtual machine images are within the ‘Latest/’ directory namespace Β Β for all builds, but I am intent on fixing it. 6) The ZFS-root EC2 AMIs panic a few seconds after booting, apparently Β Β due to memory corruption in ZFS.
Note regarding (3) above: this is not yet done, but the datasets in which the builds were done are preserved.Β I hope to have at least a few hours this weekend to try to get binary packages for the FreeBSD base system in place, wherever that ends up being.
Add the following parameters in the /etc/rc.conf configuration file:
ntpd_enable=”YES” ntpd_sync_on_start=”YES”
add the line: pool de.pool.ntp.org iburst in /etc/ntp.conf file
iburst denotes that ntpd will perform a burst of 8 quick packet exchanges with a server when contact is first established, to help quickly synchronize system time.
The de prefix differs depending on the servers of the country you choose. In my case Germany. A complete list of active servers is on https://www.ntppool.org/en/
In addition, FreeBSD provides a project-sponsored pool, 0.freebsd.pool.ntp.org.
The supported hashing algorithms are DES, MD5, SHA256, SHA512, and Blowfish but the default is SHA512
Hashes that start with $6$ are indicative of SHA512
The settings are found in /etc/login.conf where :passwd_format=sha512:\ declares the preferred hashing algorithm
In order to change the hashing method execute cap_mkdb /etc/login.conf. It will only affect the new passwords. The old ones need to be re-hashed by asking users to run passwd in order to change their password
