  • Thanks, here’s another article about this:

    https://wvutoday.wvu.edu/media-center-blog/2024/09/19/expert-pitch-from-communication-devices-to-deadly-tools-wvu-researcher-elaborates-on-explosive-potential-of-pagers-and-walkie-talkies

    The process of sabotage begins with physical modification of the pager or personal radio. These devices already contain all the essential components for an explosive device: a power source — the battery, a container — the device casing, and a triggering mechanism —the communication circuitry. The addition of a detonator and explosive charge converts them into remote-controlled bombs. A microcontroller is typically embedded within the device to interface with its circuitry, allowing it to detonate in response to external signals.

    “The triggering mechanism for these devices relies primarily on radio frequency signals, as both pagers and walkie-talkies operate on radio frequency bands. In the case of pagers, a unique radio frequency signal can be transmitted over the paging network. The modified pager, programmed to listen for this specific signal, activates the detonator when the correct frequency and signal pattern are detected.

    “Similarly, a walkie-talkie can be set to a predetermined channel and frequency. When the matching radio frequency signal is received, the microcontroller closes the circuit, triggering the explosion.

    “To ensure precise activation, the microcontroller can be programmed to recognize a unique sequence of tones or signal modulations, minimizing the risk of accidental detonation. This setup requires careful pre-programming and maybe signal testing, often involving encryption or authentication sequences to prevent unintended triggering.

    “The combination of radio frequency signals with an embedded microcontroller enables remote activation. It takes a high level of technical expertise to modify these low-tech communication tools into sophisticated remote-controlled weapons.”



  • Anyone else confused about how these bombs are actually detonating? Articles say they are detonating via a text message sent 3x in error, theoretically causing either a spark or a “closed circuit” like a different article explained. The article (from al jazeera) says they have to look at the message but there’s video of one igniting in a bag.

    I’m curious because I think these pagers may actually constitute a public safety risk, similar to how heavily landmined areas risk exploding even decades later on someone unrelated to the initial conflict.



  • You’re incredibly uneducated to be making the claims you are.

    Racism in the US south against black people looks different than racism in the midwest/Western states against Native Americans because the goals of the racism were different.

    The govt wanted to grow the black population so they could have a huge workforce to take from. Explicit racism helps a lot with this, because it’s declaring people black and enforcing that they are less than and deserve to be a lower class. This is probably what you mean about how racist the south is.

    For Native Americans, the govt’s goal is to take their land and destroy their claims to land - they want LESS Native Americans. That’s why colorblindness is the racism in the midwest and west. That is also why those areas HATE Latino people, even though those people are generally just Native Americans who speak Spanish. That’s why you hear stuff like “We speak English here.” That’s why old John Wayne movies were the way they were. That’s why we had those Native American re-education schools. That’s why we killed so mamy buffalo (to starve them) and the Great Plains to this day has never recovered fully from how many millions of herd animals were killed. It’s why, TO THIS DAY, Christian organizations will adopt Native kids to explicitly white Christian families. It’s why the Mormons are in Utah. It’s why most Native reservations are in extremely inhospitable places (look at the Navajo lands versus nearby in Hatch, NM - the Native people would have lived near Hatch, near water, but we took that from them and gave them barren soil - to kill them).

    The racism against Native Americans is like smothering and starving a baby to death, whereas the racism in the south is more like screaming//beating at a baby to depression/“submission”.

    Rec reading: Conquest: Sexual Violence and American Indian Genocide by Smith, Andrea

    Old cowboys used to cut Native women’s labia off and put it on their saddle horns to play with. The west is racist too.

    It is engagement farming for absolutely zero reason.

    So what? Should we ban people posting memes too? Should we ban the engagement system/up vote system? Like what’s your point here? That people share ideas and thoughts? Wow, what news.

    The astronauts in space are a big deal and the latest development had SpaceX rescuing them which is why that person brought it up. They weren’t bringing up Boeing originally, they were bringing up the astronaut story since it all ties together. If SpaceX is grounded, how will they get those astronauts?

    And then the next person points out that Boeing and most CEOs tend to feel like worker deaths are the cost of business. That’s pretty apropos when talking about those astronauts getting stuck up there. Worker solidarity and all.
