The xz package, starting from version 5.6.0 to 5.6.1, was found to contain a backdoor. The impact of this vulnerability affected Kali between March 26th to March 29th. If you updated your Kali installation on or after March 26th, it is crucial to apply the latest updates today.

My analysis of Bill #S210 on why online age verification is crucial but the Bill gets it wrong @mivillej. The Bill is flawed as drafted plus belongs in a broader package of child protection measures in online harms leg: ablawg.ca/2024/02/05/onl…. Thanks @ABlawg @UCalgaryLaw

@techspence @DirectoryRanger Get a Linux box to use AD for accounts via ldap and authentication with kerberos without using a fancy library or commercial product.
I fixed your headline for you: "Driver of school bus, with 11 kids on board, in Stratford charged after police say they crashed into a tree". I don't believe there were 11 kids in the tree.

I still haven't been able to visit Alcatraz.
@nixcraft I think you mean you are proficient with searching the stackoverflow website.
@markusoff @LauraOsmanCP @DCFraser @StephTaylorCP @MarieDanielle @MariekeWalsh @sproudfoot @janycemcgregor @CBCRaffy @ChrisGNardi @RyanTumilty @cath_cullen @TondaMacC @aballinga @atRachelGilmore I want an inquiry on why the province did *not* act when clearly Ottawa Police were in trouble. If there were provincial tools, why were they not used? What option did GoC have other than what they did? It's a failure of the confederation, IMO.
