Snadragon X Elite Laptop Performance On Linux Ends 2025 Disappointing
As part of my various end-of-year benchmarking comparison articles for looking at the performance evolution of Linux is a fresh look at the Qualcomm Snapdragon X Elite laptop experience when using Ubuntu 25.10 with the latest X1E Concept packages, which includes taking the X1 Elite optimized kernel to the latest Linux 6.18 stable series. Unfortunately, there are significant performance regressions observed compared to a few months ago … ⌘ Read more

YouTube Has a Firm Grip on Daytime TV
YouTube has been winning the streaming wars for years, but its real competitive advantage comes not from prime-time viewing but from its stranglehold on daytime hours when Americans are meditating, exercising, cooking, or simply looking for background noise. At 11 a.m. in October, YouTube commanded an average audience of 6.3 million viewers compared to Netflix’s 2.8 million, according to Nielsen dat … ⌘ Read more

Linux 6.20~7.0 To Bring Prep Changes For CXL Soft Reserve Recovery & Accelerator Memory
The next kernel cycle that will be known as either Linux 6.20 or Linux 7.0 depending upon how Linus Torvalds handles the versioning for this next x.20 milestone. More than likely it will be Linux 7.0 given his historical versioning scheme, but whatever the case, ahead of this next kernel cycle some initialization changes for the CXL subsystem are building up… ⌘ Read more

Open-Source Linux Driver Christmas Surprise For 20~23 Year Old Radeon GPUs
If Linux 6.19 switching from the Radeon legacy to AMDGPU kernel drivers for the GCN 1.0/1.1 GPUs for those ~13 year old GPUs isn’t nostalgic enough for you, here’s something a bit more nostalgic this holiday season: fresh open-source driver commits to the Radeon R300g driver for supporting those 23 year old ATI R300 GPUs up through the 20 year old R500 class graphics processors… ⌘ Read more

Ler fichas técnicas de sondagens é um exercício interessante - e mostra como a matemática prova mas também pode ser usada para enganar. Um exemplo: sabiam que a última sondagem para a Euronews sobre as Presidenciais perguntava às pessoas se votariam em Joana Amaral Dias, mas nunca perguntava se votariam, por exemplo, em Jorge Pinto, encaixando-o na opção “Outros”? Nos resultados dessa sondagem, Joana Amaral Dias figura com 0% de votos, contra os 0,6% de Jorge Pinto, mas deve-nos deixar a pensar… qual seria o resultado se o nome de Jorge Pinto fosse dito explicitamente? E talvez mais importante, qual foi o critério usado para incluir um dos nomes e excluir o outro?

Linux 6.19’s Significant ~30% Performance Boost For Old AMD Radeon GPUs
For those still using old AMD GCN 1.0 “Southern Islands” or GCN 1.1 “Sea Islands” graphics cards, the upcoming Linux 6.19 kernel is a wonderful holiday gift. With Linux 6.19, the GCN 1.0/1.1 GPUs are now defaulting to the modern AMDGPU kernel driver in place of the legacy “Radeon” DRM driver that has been the default for GCN 1.1/1.0 and other ATI/AMD graphics processors of the past 2+ decades. In this article is a look at the performance ben … ⌘ Read more

#ptpol #debate #presidenciais

1 - #LMM e nomes de clientes - ambos acham que é preciso transparência

2 - suspensão de mandato - #Cotrim não pode, #Ventura já suspendeu

3 - TC lei da nacionalidade - Cotrim tem pena que TC tenha chumbado, mas gosta da lei e quer que avance sem os problemas constitucionais, Ventura insiste na lei toda mesmo a parte anticonstitucional

4 - EUA quer extrema-direita na EU - Ventura é pró-Trump, Cotrim concorda com Trump numas coisas e discorda noutras

5 - última sondagem - Cotrim acha que Ventura é só alarido (e amigo de pedófilos), Ventura tem orgulho de estar em primeiro lugar em todas as sondagens

6 - pensões - Cotrim quer pensões privadas, Ventura quer subir pensões ao nível do salário mínimo, “cortando nas gorduras” (gostava de ver essa proposta de lei… e de qq forma, isso não é medida presidencial - não que ele queira ser presidente). Na palavra final, Cotrim apela o voto dos eleitores do Chega nele em vez de Ventura

Considerações pessoais: asco. Um mau, outro inqualificável. Não me surpreende que discutem eleitorado, mas preocupa-me que esse eleitorado exista. Não me interpretem mal, se isto fosse a segunda volta obviamente que sem qualquer dúvida seria Cotrim a ter o meu voto, mas… ew.

2/n
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

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

• Step 6. Unpack the assets into server/

• Step 7. Build backend with make cli-linux-server

• Step 8. Done
