Early Linux 6.19 Benchmarks On AMD EPYC 9965 2P Excelling For AI & HPC Performance
As the Linux 6.19 merge window winded down this weekend, I began running this development kernel on more systems. While there are some scheduler regressions currently with Linux 6.19 Git, for HPC workloads especially I am seeing some encouraging results using a flagship AMD EPYC 9965 2P server configuration. ⌘ Read more
Linux 6.19-rc1 Released From Japan
The Linux 6.19-rc1 kernel is out to cap off the Linux 6.19 merge window. The kernel release is coming the better part of a day earlier due to Linus Torvalds being in Japan for this past week’s Linux Plumbers Conference and Linux Kernel Maintainer Summit… ⌘ Read more

CM explica que OEs não são moções de censura, apontando a agulha da irresponsabilidade a LMM. LMM acha que CM não explicou o chumbo só OE (espero que ela responda).
3 - migração: LMM acha que as medidas foram boas, e as mas repercussões também vão ser resolvidas com os efeitos da vida verde. CM anda atrás para responder em relação ao chumbo do OE, para dizer que a situação da Saúde hoje prova que o Bloco tinha razão. CM aponta que até o Governo já vai recalibrar a via verde porque ela não funciona. Relembra que estes números de hoje provam que os migrantes não vêm para ser subsidiodependentes como alguns dizem, pelo contrário
4 - Chega - CM não dará posse a PMs que não têm condições, como manda a constituição. Não quer passar a campanha a falar de um governo do Chega que não vai acontecer. LMM dá se tiver acordo escrito. E se não cumprir o acordo? “Isso não me passa pela cabeça” (porque nós nunca vimos o Ventura a mudar de conversa de um dia para o outro certo?)
5 - Saúde - LMM critica CM ser contra as PPP. CM lembra o dono da PPP que recusa a atender pacientes que não sejam rentáveis. Saúde tem de ser para todos (tal como diz a constituição).
6 - Europa - CM fala da proposta europeia sobre pensões e o perigo que isso é. Fala da ingerência de Trump na Europa. É solidária com Ucrânia

Alright, Advent of Code is over:
https://www.uninformativ.de/blog/postings/2025-12-12/0/POSTING-en.html
It’s been quite the time sink, especially with the DOS games on top, but it was fun. 🥳
In case you’re wondering: All puzzles (except for part 2 of day 10) were doable in Python 1 on SuSE Linux 6.4 and ran in a finite time on the Pentium 133. Puzzle 10/2 might have been doable as well if I had better education. 🤣
Linux 6.19 Improves User-Space I/O “UIO” With Shared Virtual Addressing

Cache Aware Scheduling Raises Performance For Intel Xeon 6 Granite Rapids
Over the past year Intel engineers have worked a lot on Cache Aware Scheduling for the Linux kernel. The yet-to-be-merged functionality allows for the Linux kernel to better aggregate tasks sharing data to the same last level cache (LLC) domain to reduce cache misses and cache bouncing. The Cache Aware Scheduling development was led by Intel but helps other CPU vendors too for processors with multiple cache domains. Back in October I show … ⌘ Read more

3 - Europa e Ucrânia - CM defendeu no parlamento europeu que a Europa devia reforçar os meios de defesa da Ucrânia, mas está contra uma escalada militar, o caminho tem de ser a Paz, mas não a solução de capitulação de Trump. AF (q destaca q isto não é assunto para um presidente) diz que é errado q se chega à paz enviando armas, não acha bem enviar armas aos palestinianos e portanto também não acha bem enviar à Ucrânia. Agressor e agredido na Rússia e Ucrânia?
4 - Nobel da Paz e Venezuela - CM condena Maduro, mas também o Nobel de Paz. AF diz que estão de acordo.
5 - CM não deixa debate chegar ao fim sem pedir à RTP para repensar a sua posição no que diz respeito à Eurovisão, AF concorda.
6 - Jovens e anonimato nas redes sociais - AF acha que vale a pena fazer esses debates. AF é “contra o anonimato na internet” mais ou menos. CM diz que a cena dos jovens é se calhar como o Tabaco. Anonimato vs. Segurança é falsa dicotomia.
7 - Estranha última pergunta, um bocado saída do nada, e surpreendentemente isso é onde se vê uma diferença de opinião: com AF (mal) a criticar o anonimato na net, CM (bem) a defendê-la.

Considerações pessoais: mais um debate entre os “candidatos bons”, sem surpresas a não ser no final com AF espantosamente s atacar o direito (e protecção graças) ao anonimato

4 - Justiça: #Seguro diz que a Justiça precisa de ser esclarecer, o problema não é as leis mas sim o seu não cumprimento. #GouveiaEMelo acha que Ministério Público tem de ser como a mulher de César. Estão alinhados.
5 - Defesa: Seguro é um Europeísta. GEMelo não é europeísta, é “um pé na Europa, um pé no Atlântico”. Qual é a diferença? GeM não sabe dizer. GeM diz que os investimentos estão a ser mal feitos porque Presidente não tem visão, mas o presidente não tem nada a haver com isto, é o Governo e no máximo a AR. Seguro quer Comprar Europeu, tecnologia dual Europeia, GeM também - ambos concordam que ainda não podemos fazer isso.
6 - Guerra e Paz: entramos em Guerra se as coisas caminharem nessa direção? Nenhum dos dois respondeu, falaram mais do tema anterior que é menos perigoso para o eleitoralismo.
-
Conclusão/considerações pessoais: dois maus candidatos, mas isto serviu para me consolidar na ideia que GeM é pior. Tenho curiosidade em ouvir MM a falar nalguns destes temas, para ver se está mais alinhados com o Governo (por exemplo com a conversa do salário mínimo), para comparação. Apesar de ter ficado com a ideia de GeM ter sido pior (aquela “pequena política” inicial provavelmente influenciou-me) foi Seguro quem deixou passar medidas inconstitucionais, e não vê nada de errado

Scheduler Woes: Bisecting Early Performance Regressions Found In Linux 6.19
Yesterday I noted some early performance regressions I’ve found on the Linux 6.19 kernel compared to Linux 6.18 LTS stable. Those initial benchmarks were on an AMD EPYC server. Since then I’ve seen many of the same workloads regressing similarly on an AMD Ryzen Threadripper workstation between Linux 6.18 and Linux 6.19 Git. Given the significant impact and AMD Threadripper processors always helping out to speed-up Linux kernel build time … ⌘ Read more
