Why bother inventing conspiracies?

Perception management is a term originated by the US military.[citation needed] The US Department of Defense (DOD) gives this definition:
Tuskegee Study of Untreated Syphilis in the Negro Male[a] was a clinical study conducted between 1932 and 1972 by the U.S. Public Health Service.[1][2] The purpose of this study was to observe the natural history of untreated syphilis; the African-American men in the study were only told they were receiving free health care from the United States government.[3]
Here's how cellulite came to be the most endemic and untreatable “invented disease” of all time.
Propaganda Due (Italian pronunciation: [propaˈɡanda ˈduːe]; P2) was a Masonic lodge under the Grand Orient of Italy, founded in 1877. Its Masonic charter was withdrawn in 1976, and it transformed into a clandestine, pseudo-Masonic, ultraright[1][2][3] organization operating in contravention of Article 18 of the Constitution of Italy that banned secret associations. In its latter period, during which the lodge was headed by Licio Gelli, P2 was implicated in numerous Italian crimes and mysteries, including the collapse of the Vatican-affiliated Banco Ambrosiano, the murders of journalist Mino Pecorelli and banker Roberto Calvi, and corruption cases within the nationwide bribe scandal Tangentopoli. P2 came to light through the investigations into the collapse of Michele Sindona's financial empire.[4]
Operation Gladio is the codename for clandestine "stay-behind" operations of armed resistance that was planned by the Western Union (WU), and subsequently by NATO, for a potential Warsaw Pact invasion and conquest in Europe. Although Gladio specifically refers to the Italian branch of the NATO stay-behind organizations, "Operation Gladio" is used as an informal name for all of them. Stay-behind operations were prepared in many NATO member countries, and some neutral countries.[1]
La strategia della tensione in Italia è una teoria politica che indica generalmente un periodo storico molto tormentato della storia d'Italia, in particolare negli anni settanta del XX secolo, conosciuto come anni di piombo e che, mediante un disegno eversivo, tendeva alla destabilizzazione o al disfacimento degli equilibri precostituiti.

Il coriandolo (Coriandrum sativum), noto anche come cilantro, suo nome spagnolo, è una delle erbe aromatiche più antiche che si conoscano. Citato nella Bibbia, i suoi semi sono stati ritrovati in tombe egizie e in epoca romana era usato sia come erba medicinale che come condimento. L’uso culinario delle foglie fresche e dei semi essiccati si è poi diffuso in tutto il mondo e ora è molto utilizzato nelle cucine del Messico e dell’America Latina per preparare la tradizionale salsa che accompagna le tortillas, nel Medio Oriente e in alcuni paesi asiatici come la Tailandia e l’India per aromatizzare molte ricette.

Come previsto, è già quasi sparito dal dibattito pubblico il vero macrofenomeno emerso dalle elezioni del 31 maggio, cioè la diserzione delle urne. Eppure non era mai accaduta una cosa così: ad esempio, che in due grosse regioni come Toscana e Marche

One day after the first deploy, we went to check how the system was doing, and noticed some fine tuning to do, some pretty much urgent.

Another surprise hits us at the last moment: if the system boots without an HDMI monitor plugged in, no framebuffer device is ever created, and X will not start, lightdm will give up after some tries, and even if one plugs in a monitor afterwards, it will stay blank until a reboot or some kind of manual intervention.

As a workaround, one can configure the bootloader to force a specific HDMI configuration. This post documents how we did it.

Provisioning a SD card starting from the official raspbian-lite is getting quite slow, since there are a lot of packages to install.

It would be significantly faster if we could take a SD card, partition it from scratch, then untar the boot and rootfs partition contents into them.

Here's how.

This is a comic about the backfire effect.
The Barnum effect, also called the Forer effect, or less commonly the Barnum-Forer effect, is a common psychological phenomenon whereby individuals give high accuracy ratings to descriptions of their personality that supposedly are tailored specifically to them, that are in fact vague and general enough to apply to a wide range of people. This effect can provide a partial explanation for the widespread acceptance of some paranormal beliefs and practices, such as astrology, fortune telling, aura reading, and some types of personality tests.

“Slim by Chocolate!” the headlines blared. A team of German researchers had found that people on a low-carb diet lost weight 10 percent faster if they ate a chocolate bar every day. It made the front page of Bild, Europe’s largest daily newspaper, just beneath their update about the Germanwings crash. From there, it ricocheted around the internet and beyond, making news in more than 20 countries and half a dozen languages. It was discussed on television news shows. It appeared in glossy print, most recently in the June issue of Shape magazine (“Why You Must Eat Chocolate Daily,” page 128). Not only does chocolate accelerate weight loss, the study found, but it leads to healthier cholesterol levels and overall increased well-being. The Bild story quotes the study’s lead author, Johannes Bohannon, Ph.D., research director of the Institute of Diet and Health: “The best part is you can buy chocolate everywhere.”

A month later, we tried building an himblick image and it stopped playing video with vlc, only showing a black screen.

Although we're working with Rasbian Buster, and Debian Buster is stable, it looks like Raspbian Buster is not stable at all.

Time to learn how to freeze a partial raspbian mirror.
