Nearly Divisionless Random Integer Generation On Various Systems
Naively, you could take the random integer and compute the remainder of the division by the size of the interval. It works because the remainder of the division by D is always smaller than D. Yet it introduces a statistical bias. You can do better without being slower. The conventional techniques supported in Java and Go require at least one or two integer division per integer generated. Unfortunately, division instructions are relatively expensive.


This algorithm is a practically-divisionless approach which performs a good bit faster on all 3 tested architectures.

Brexit Standard - Polscy neonaziści przyznali się do podżegania do terroryzmu
19-letni Michał Szewczuk z Leeds przyznał się do zachęcania do terroryzmu i do posiadania dokumentów przydatnych terrorystom. Wcześniej do zachęcania do terroryzmu przyznał się także 18-letni Oskar Dunn-Koczorowski z zachodniego Londynu.

Zarzuty wobec nastolatków dotyczą przynależności do grupy neonazistowskiej zwanej Sonnenkrieg Division, która przygotowała materiały nawołujące do zabójstwa księcia Harry'ego za to, że jest „zdrajcą rasy”, po tym gdy poślubił amerykańską aktorkę Meghan Markle. Wychwalała także norweskiego mordercę Andersa Breivika.

Według BBC Szewczuk, używając fałszywego konta na portalu społecznościowym Gab, nawoływał do „systematycznych zabójstw kobiet” i gwałtów na dzieciach.

'All I hear is anger and frustration': how Brexit is affecting our mental health | Politics | The Guardian
The disconnect between what some people feel – more than six million signed the revoke petition – and what it is assumed that everyone feels (they want to leave, now; they voted once and don’t want to say it again), leaves huge swathes of the population with their political views denied, rendered inauthentic. What if you’re in favour of free movement? What if you think sovereignty is a stupid thing to get worked up about? What if you never thought international collaboration on lawmaking was a bad thing? What if you didn’t see it as losing control? You’re not just outside political parties and discourse, you are a non-person, stateless in Brexitland. And if your civic identity is quite central to your sense of self, that’s hard to take.
