Again, there’s something that seems be rare on the net, and that’s the problem of finding the ordered list of vertices of a negative-cycle in a directed or undirected graph[1]. Well, the Bellman-Ford algorithm already finds out that there’s a negative cycle, but how can we make it to also list the vertices of that [...]

Despite a wealth of security knowledge and developers’ access to advanced tools, many software security risks remain. Analysts say that vulnerabilities arise because many software developers do not understand how to build security into their code. “There’s a lot more acceptance of security as part of the process now, but historically developers have never been [...]

The teacher constrained each topic to be arbitrarily assigned to only one team. There were 22 topics totally. I was standing from 9:15 AM there, and [...]

But as the technology enhanced, the filtering system became more complicated and the old ways were no longer working. Now, there are a dozen of dead and half-alive methods commonly used. Unfortunately, almost most of [...]
