Как ядро Linux решает, какой процесс «убить» при нехватке памяти
В сентябре 2004 года разработчик Томас Хабетс вернулся к рабочей станции и обнаружил, что его экран разблокирован. Память закончилась, OOM Killer выбрал жертву и завершил xlock... Для того, чтобы больше такого не произошло Хабетс предложил список процессов, которые Linux запрещено убивать даже в такой ситуации. Его патч в ядро не вошёл, но позже разработчики добавили настройку приоритетов, поддержку cgroups и отдельный поток для быстрого освобождения памяти. Несмотря на это, OOM Killer всё равно может снести важный процесс, ведь ядро видит только объём памяти и заданные администратором правила. Если правил нет, то Linux сам решает, кого «убить». Почему и что делать, чтобы этого не произошло — в статье. Читать

1/n Notes on #UAP Discussions : Because the subject matter has a long history (and developed its own unique culture here in the U.S ) there are lots of opportunities for confusion regarding overlaps / connections that are evidentially tenuous at best.
Researchers that study #Precognition or other #Psi phenomenologies in the context of #Neuroscience or #Physics don’t generally find that work connects in any way to UAP / NHI . It’s the same for most others trying to understand #NDE’s, #OBE’s and -
"Wüstenstaub in Europa nimmt zu"
Untersuchung des #PSI (Paul Scherrer Institut) in #Nature veröffentlicht:
"Die Belastung steigt – und könnte sich durch den Klimawandel weiter verschärfen."

1/2 Monday #NoeticSpectrum : I've argued before that once a #Physics approach becomes dominant in studying #Psi phenomenologies the term #Parapsychology no longer fits. In the mean time there are plenty of confusions for laypeople regarding what people mean when they say a thing is "nonphysical" . In physics when we talk of weakly interacting or massless regimes there is some precision.
In most other contexts people will conflate "spirit" and "consciousness" with "nonphysical" The problem... -
1/2 Tuesday #NoeticSpectrum : #Mind and #Brain are not the same thing. This is why #Psi channels in humans are very noisy. Denoising is nontrivial and almost biometric when it comes to individuals. Think fingerprints. Individuals can at best do a single experimental trial at a time. The data won’t generalize to larger populations and there are no proxies. Other than that it’s huge fun if you have the patience...

Studie: Neue AKW lohnen sich nur mit staatlicher Unterstützung

".. in der Schweiz sind laut einer neuen Studie unter den heutigen Bedingungen nicht konkurrenzfähig. Rentabel könnten sie nur mit staatlicher Förderung, Risikoabsicherung und deutlich tieferen Baukosten werden. .."pdf: https://www.research-collection.ethz.ch/bitstreams/6c2d72b7-d4e5-4940-8986-349de97aa1d5/download

Less wired, more weird.
I have just finished reading ‘The Science of Magic’ by Dean Radin. This is a book about psi phenomenon (a vast set of topics some of which I have listed below).
I have always found the possibility of the psi being veridical, fascinating…and, as I mature in my own contemplative practices, increasingly compelling.
The mainstream scientific community (at least publicly) decry most psi phenomena as woo. Despite many studies now showing experiences such as Telekinesis and clairvoyance having small but statistically significant effects1. And despite their willingness to embrace the equally woo manifestations of quantum physics (such as entanglement or the weirdness of how our consciousness impacts reality, the so-called observer effect).
Personally, I have differing views on the various topics of psi. Yet I like to keep an open mind on some of the claims I find more fantastical.
How about you?
Tom Morgan over at The Leading Edge, has come up with a quick (4 min) test to help you reflect on your own beliefs around psi:
You can take the ‘How woo are you?’ test here: https://howwooareyou.netlify.app/
Here are my own results.
List of some Psi phenomenon:
- Telepathy: The direct transmission of thoughts, feelings, or images from one mind to another without using words, gestures, or known sensory channels.
- Clairvoyance: The ability to gain information about an object, person, location, or physical event through means other than the known human senses.
- Precognition: The ability to see or experience future events before they happen.
- Remote Viewing: A specific protocolized method of attempting to describe a distant target (location, person, or event).
- Psychometry: The ability to obtain information about an object’s history or the people associated with it merely by touching or holding the object.
- Telekinesis (Psychokinesis – PK): The direct manipulation of matter using only the mind, without any physical interaction.
- Healing: Curing illness or injuries through touch, distance, or intention.
- Near-Death Experiences (NDEs): While primarily a physiological/psychological event, the veridical component (seeing things while clinically dead that could not be seen otherwise) is sometimes analyzed as a form of psi (out-of-body perception).
- Synchronicity: A concept introduced by Carl Jung describing “meaningful coincidences” that seem causally unrelated but are connected by meaning.
- This is assuming of course that the studies are methodologically sound and of high quality (which many seem to be) ↩︎

We don't need #xmpp with "consistent user interfaces" (for the user) – that's from #Psi+ to #Movim. Nothing in common, except what's under the hood.

1/n #Quantum States as #Classical Sensors Dept: For work in #Precognition and #Augmented #Psi there are two generalizations useful for different purposes - The applications fork can be independent of theoretical constraints. In other words you can generate data for quantitative / qualitative corollation without asking what the mechanism is...
In the Foundational fork your looking for the theory - your trying to determine mechanism or some variable dependent on mechanism - encodings, signal... -
Mi sistema andaba un poco lento cuando terminé de editar el video sobre memoria libre, disponible, y la métrica PSI en Linux, y efectivamente, el sistema estaba bastante colapsado.
Dato: tengo 15G de RAM, y estaba bastante libre.
Conclusión: el cuello de botella era el acceso a disco.
Estuve tuneando un poco algunos daemons que usan I/O intensa, como syncthing, para optimizar un poco.
Debería documentarlo, no? 😅

🚀 Operando4NeXus Kick-off in Berlin!
The #HMCproject #Operando4NeXus has started. Partners met in #Berlin to align on goals and kick off collaboration.
The project advances #interoperability and #metadata integration in the #NeXus standard, supporting #FAIRdata in photon & neutron science.
Great exchange with @fairmat_nfdi @DAPHNE4NFDI & #SECoP@HMC — metadata is teamwork!

No entendía por qué mi máquina virtual con #devuan andaba tan lenta, y claro, el problema fue capa 8: yo mismo le configuré 512MiB de RAM 😅
Sí, estoy haciendo pruebas de estrés en el sistema, análisis de memoria libre, disponible, load average, y PSI.
El video que estaba preparando sobre estos temas se está extendiendo mucho... creo que van a salir 2 videos, para poder sumergirnos más en algunos detalles 😃

Armando el guión para un nuevo video en el canal de YouTube de #JuncoTIC, intentando responder dudas de algunos alumnos, me encontré con el PSI (Pressure Stall Information) para medir la latencia en sistemas Linux, y detectar cuellos de botella en memoria, CPU, etc.
Voy a intentar añadirlo al vídeo! Creo que les va a gustar.
Además, irá también al curso de Admin Linux (LPIC)
