2021 retro-link! blog.cleverelephant.ca/2021/05 - PostGIS at 20: the beginning.

PostGIS at 20, The Beginning
Twenty years ago today, the first email on the postgis users mailing list (at that time hosted on yahoogroups.com) was sent, announcing the first numbered release of PostGIS. The early history of PostGIS was tightly bound to a consulting company I had started a few years prior, Refractions Research. My first contracts ended up being with British Columbia (BC) provincial government managers w...

On the Constants of the Lang-Trotter Conjecture for CM Elliptic Curves
In 2021, Daqing Wan and Ping Xi studied the equivalence of the Lang-Trotter conjecture for CM elliptic curves and the Hardy-Littlewood conjecture for primes represented by a quadratic polynomial. Wan and Xi provided an alternative description of the Lang-Trotter conjecture under the Hardy-Littlewood conjecture. They obtained an explicit constant $\overlineω_{E,r}$ in the asymptotics of the Lang-Trotter conjecture. They further conjectured that this particular constant would be equal to the con…

Wavelet-based Edge Multiscale Parareal Algorithm for subdiffusion equations with heterogeneous coefficients in a large time domain
We present the Wavelet-based Edge Multiscale Parareal (WEMP) Algorithm, recently proposed in [Li and Hu, {\it J. Comput. Phys.}, 2021], for efficiently solving subdiffusion equations with heterogeneous coefficients in long time. This algorithm combines the benefits of multiscale methods, which can handle heterogeneity in the spatial domain, and the strength of parareal algorithms for speeding up time evolution problems when sufficient processors are available. Our algorithm overcomes the challe…

Las Vegas Raiders defensive end Maxx Crosby compares Christian Wilkins to 2021 teammate
The Las Vegas Raiders have not had the defense they have needed to make the playoffs in the last 20 years. It takes both sides of the ball, and rarely do teams make the postseason when they are very bad on one side of the ball and average or below average on the other side. That has been the story of the Raiders since their last playoff win, two decades ago. It's always one or the other for the Raiders, and in the last 10 years or so, it has mainly been the offense that performs better. Last ye…
