[alt-text for the vision-impaired] Image appears to be a twitter post from Craig Murray posted on 2023-10-14: "To be entirely plain. I have always viscerally opposed war. I have dedicated my life to conflict resolution and reconciliation. But in the coming Gaza genocide, every act of armed resistance by Hamas and Hezbollah will have my support. If that is a crime, send me back to jail."

Hmm. Could be seen as a rather outlandish thing to say in the immediate aftermath of 2023-10-07, but in hindsight with what we know now in terms of what atrocities the Israeli military forces have brought upon the people of Gaza since that attack on Israel, it seems a reasonable statement to support armed resistance against the coming episode of genocide which indeed materialised and continues today.

The coordinated decision of the Western nations to fast track famine by stopping UNRWA funding was announced within an hour, following the ICJ ruling that Gazans were at immediate risk of genocide, and drove from the media headlines the adverse ruling against Israel.

Just like colesworth suppliers, plant nurseries and other suppliers suffer the same way as highlighted in recent news and inquiries into the supermarket sector.

[...] the attack is an extremely expensive nation state level operation that doesn’t scale.

About $250 at most. Quoting the linked page:

Below is a list of equipment we used for the experiments.

  • (1) Software Defined Ratio (SDR): Ettus USRP B210 USRP, ~$2100.
  • (2) Low Noise Amplifier (LNA): Foresight Intelligence FSTRFAMP06 LNA, ~$200.
  • (3) Directional Antenna: A common outdoor Log-periodic directional antenna (LPDA), ~$15.
  • (4) A laptop, of course.

Note that the equipment can be replaced with cheaper counterparts. For example, USRP B210 can be replaced with RTL-SDR that costs ~$30.

To reproduce the attack: our GitHub repository provides the codes and instructions for reproducing and understanding the attack. We have prepared a ready-to-use software tool that can produce real-time reconstructions of the eavesdropped videos with EM signal input from the USRP device.

EM Eye investigates a cybersecurity attack where the attackers eavesdrop on the confidential video data of cameras by parsing the unintentional electromagnetic leakage signals from camera circuits. This happens on the physical/analog layer of camera systems and thus allows attackers to steal victim's camera data even when perfect software protections (e.g., unbreakable passwords) are all in place. Exploiting the eavesdropped videos, attackers can spy on privacy-sensitive information such as people's activities in an enclosed room recorded by the victim's home security camera. [...]

In U.S. Pacific Northwest coho salmon (Oncorhynchus kisutch), stormwater exposure annually causes unexplained acute mortality when adult salmon migrate to urban creeks to reproduce. By investigating this phenomenon, we identified a highly toxic quinone transformation product of N-(1,3-dimethylbutyl)-N′-phenyl-p-phenylenediamine (6PPD), a globally ubiquitous tire rubber antioxidant. Retrospective analysis of representative roadway runoff and stormwater-affected creeks of the U.S. West Coast indicated widespread occurrence of 6PPD-quinone (<0.3 to 19 micrograms per liter) at toxic concentrations (median lethal concentration of 0.8 ± 0.16 micrograms per liter). These results reveal unanticipated risks of 6PPD antioxidants to an aquatic species and imply toxicological relevance for dissipated tire rubber residues.

Humans discharge tens of thousands of chemicals and related transformation products to water (1), most of which remain unidentified and lack rigorous toxicity information (2). Efforts to identify and mitigate high-risk chemical toxicants are typically reactionary, occur long after their use becomes habitual (3), and are frequently stymied by mixture complexity. Societal management of inadvertent, yet widespread, chemical pollution is therefore costly, challenging, and often ineffective.

On November 16th, Meredith Whittaker, President of Signal, published a detailed breakdown of the popular encrypted messaging app’s running costs for the very first time. The unprecedented disclosure’s motivation was simple - the platform is rapidly running out of money, and in dire need of donations to stay afloat. Unmentioned by Whittaker, this budget shortfall results in large part due to the US intelligence community, which lavishly financed Signal’s creation and maintenance over several years, severing its support for the app.

Never acknowledged in any serious way by the mainstream media, Signal’s origins as a US government asset are a matter of extensive public record, even if the scope and scale of the funding provided has until now been secret. The app, brainchild of shadowy tech guru ‘Moxie Marlinspike’ (real name Matthew Rosenfeld), was launched in 2013 by his now-defunct Open Whisper Systems (OWS). The company never published financial statements or disclosed the identities of its funders at any point during its operation.

Sums involved in developing, launching and running a messaging app used by countless people globally were nonetheless surely significant. The newly-published financial records indicate Signal’s operating costs for 2023 alone are $40 million, and projected to rise to $50 million by 2025. Rosenfeld boasted in 2018 that OWS “never [took] VC funding or sought investment” at any point, although mysteriously failed to mention millions were provided by Open Technology Fund (OTF).

OTF was launched in 2012 as a pilot program of Radio Free Asia (RFA), an asset of US Agency for Global Media (USAGM), which is funded by US Congress to the tune of over $1 billion annually. In August 2018, its then-CEO openly acknowledged the Agency’s “global priorities…reflect US national security and public diplomacy interests.”

As per the quote below, a car loses about 0.08g of tread per km.

Compared to a car, a bike tyre is about the same diameter, 10% of the width (~20mm), 28% usable tread depth (~2mm), has 50% less wheels, and can travel 10% the distance (~10000km).

This suggests a (very approximate) tread loss of 0.08 * 10% * 28% * 50% / 10% = ~ 0.01g per km for bicycles.

For replacing longer car journeys less typically travelled by bicycle, rail transport is the best solution and removes the issue of tyre wear.

Quoting [deleted] in r/theydidthemath:

Using the same assumptions as above (215/60R16 tires, 7mm of tread loss over 100,000 km), I estimate the loss of tread by volume from each tire as follows:

Cylinder with a diameter of 664 mm and a height of 215 mm has a volume of 74,412 cm3. Cylinder with a diameter of 664-(2x7)=650 mm and a height of 215 mm has a volume of 71,307 cm3. The volume difference between a new and worn out tire is 3105 cm3.

Typical land to sea ratio of tires is 60-70% land, depending on the type of tire. If we go with an about average value of close to 65% tread, we get the lost rubber volume of about 2000 cm3 or 2,000,000 mm3 over a single tires lifespan.

Each revolution of a tire loses about 0,04 mm3 of tread, which, according to Wolfram Alpha, is a bit less than the volume of a medium grain of sand.

If we look at the entire car with 4 tires over a kilometer of road, we get 80 mm3 or about 0,08 grams of tread lost per car per kilometer.

I agree. It's just the title ABC News had on its article.

Following the "unprecedented price rises" in the past year for retail electricity rates across Australia, it looks like we have some "unprecedented price drops" just around the corner!

I'm not sure whether I need to end this post in a /s or not.

Alt-text: Line graph of annual avg wholesale electricity prices in NSW/QLD/SA/TAS/VIC over F.Y. ending 2010-2024. 2022,2023 show an increase of 100~130% compared to 2021; 2024 shows a return to ~2021 prices (except SA).

Excerpt from article:

“We all play a role in keeping our roads safe and Crime Stoppers Victoria is offering vulnerable pedestrians the tools they need to use our roads safely,” she [Crime Stoppers Victoria Chief Executive Stella Smith] said.

“We have seen 175 pedestrians killed on our roads over the last five years, and a significant number of those have been in 60 km/h zones.

“We hope with more education and awareness we can reduce the number of injuries and most importantly, deaths on our roads.”

As part of the campaign, Crime Stoppers Victoria will hit the streets to actively engage with high-risk pedestrians to educate them on how they can help keep our roads incident-free.

I guess that means police will be out in force handing out fines to pedestrians and cyclists. "Job done!"
