Firearm laws in Canada are very strict, and not comparable to the American system. No serious Canadian politician is advocating for lax gun laws or an American-style system in terms of firearm ownership.

Under Trudeau, the first major Liberal movement on banning so-called assault style firearms came after the tragedy in Portapique. The gunman in that massacre used firearms smuggled from the States, and a pistol stolen off of an RCMP officer. The shooter was reported to the RCMP for having illegal firearms repeatedly, and months/years before the shooting occurred. So, I think it's important to point out that no measure that the Liberals have moved on since 2020 would have changed the outcome in Portapique. That's why law abiding firearm owners are pushing for increased enforcement, instead of new measures that uniquely target them.

Cheers.

Even 304 stainless steel will corrode slightly in the presence of strong acids or bases, and my bet is what you're tasting are particles coming off from that thin corroded layer. Those particles aren't volatile, so you won't smell them, but it makes sense that you would taste them.

If you're sensitive to metallic flavours and want to avoid them, seek out 316 stainless steel for kitchen implements and tools. 316 is more resistant to corrosion from acids and salts. It's more expensive than 304, but it will last longer. You'll see 316 used a lot in commercial food production, things like dairy, beer & wine, exactly because those things are acidic, and 316 is more resistant to corrosion.

Not a scientist, but, interested in these things.

I would say it's because spicy foods have highly volatile aroma compounds. Tannin and acids aren't as volatile. Any aroma we perceive is the result of volatile molecules, solubalized in our mucus, binding to receptor sites in our olfactory epithelium - in other words, olfaction is a chemical sense. The tannic mouthfeel of a dry red wine is (if I'm not mistaken) a result of nonvolatile acids acting mechanically on the tongue, so olfaction, a chemical sense, doesn't come into play in that mechanical sensation of acidity. Also consider that the tannins in a red wine are in a liquid solution. Fine, dry citric acid powder will irritate the nose if you breathe in the particles, just like fine dry cayenne pepper will.

Not sure what you mean with cooling. Something like camphor is highly volatile, and gives a cooling aromatic sensation. Think eucalyptus, fisherman's friend, vick's vapo rub, things like that. Do those smell cooling to you?

Metals don't have volatile aromatic compounds in them at low temperatures, but, they definitely smell like something when they're red hot. Again, the idea here is that metals are heavy and nonvolatile, so they're invisible to our noses at room temperature, unlike say, a freshly sliced jalapeno pepper. Out of curiosity, what tastes metallic to you?

I disagree.

Don't forget that China is an oppressive dictatorship that is actively antagonistic to Canadian sovereignty. Consider the risks that increased Chinese government surveillance would pose to Chinese Canadians who speak out against China, and the increased control their government would have as a result. Just because you don't believe you have anything to hide, doesn't mean that nobody has anything to hide.

Consider also, that on an atomic level, data isn't powerful, but it is powerful in aggregate. Consider the realtime advantage a hostile foreign power would have in a wartime scenario with cameras and microphones in even a fraction of the vehicles on the road.

Chinese EVs are a very bad idea for national security and they shouldn't be allowed in Canada under any circumstance. These concerns don't extend to Japan, South Korea, or Europe, they aren't actively antagonistic to Canadian sovereignty.

I hope this is a lever Canada uses to get China to fuck off with their foreign interference, and stop trying to flood our auto market with their trojan horse spy EVs.

Counterpoint - we're all going to die. There's no good reason to feel guilt or shame for filling our lives with things that enrich our short time on this rock.

Almost anything we choose to do that is fun or interesting shortens our lifespan. So does worry, and boredom.

People who want to min-max and optimize their life and health, I guess, why not. But that's not the only way to live a meaningful life.

I'm looking to self publish a book, and am looking for book printers that print in Canada.

Companies like Mixam & Sure Print & Design are based in Ontario, but they don't advertise that their printing is done in Canada. Is it correct to assume that they do it elsewhere, if they don't clearly disclose where their printing is done?

After announcing his departure, Prime Minister Justin Trudeau tried to reach an agreement with opposition leaders so that his government would survive a few more weeks in Parliament, Radio-Canada has learned.

Sources said the day after announcing he would resign on Monday, the prime minister personally called the leaders of the New Democratic Party and the Bloc Québécois.

He wanted to obtain a commitment from one or the other to vote in favour of the budget appropriations — a vote of confidence — at the end of March, once prorogation had passed, the sources said.

That vote of confidence would have ensured the survival of the government for a few more weeks and given the Liberal Party of Canada more time to elect its new leader.

But Trudeau's gambit faltered, with both the Bloc and the NDP refusing to back the embattled prime minister as they stood by their respective promises that they would bring down the government at the first opportunity.

 

The federal government announced new gun control measures Thursday, adding several hundred models and variants to its list of banned weapons.

"These firearms can no longer be legally used, sold or imported in Canada," Public Safety Minister Dominic LeBlanc told reporters.

The announcement comes one day before the 35th anniversary of the massacre at École Polytechnique de Montréal. Radio-Canada first reported the news earlier Thursday.

The new measures, which are effective immediately, list more than 300 makes and models of assault-style firearms as prohibited weapons.

There will be an amnesty period until Oct. 30 of next year for current owners to comply with the ban. The new models will be part of the government's planned buy-back program — the program still has not collected a single gun.

Edit: According to Minister of Public Safety Dominic LeBlanc, the list of newly banned guns is currently unavailable and its exact date of release is undefined.

The RCMP stated that the list of banned guns would be available "very shortly". Exactly where the list of banned guns would be available to read was not disclosed.

BARRHEAD, Alta. — Residents of a northern Alberta town have voted in favour of a bylaw banning Pride flags and rainbow crosswalks from municipal property.

The town of Barrhead, located about 120 kilometres northwest of Edmonton, says 1,145 votes were cast in the plebiscite, with 653 in favour of the proposed bylaw and 492 opposed to it.

Active-duty conditions may lead to sleep loss, which can impair warfighter alertness and performance. Current state-of-the-art approaches for maintaining alertness following sleep deprivation include the use of drugs such as caffeine, and for U.S. military personnel undergoing long-duration training or missions, prescription stimulants, such as dextroamphetamine, may be prescribed. These stimulants have been shown to improve performance on vigilance tasks, alertness, and cognitive performance, but they can also negatively impact mood, have the potential for addiction, and may demonstrate a long circulation time in the bloodstream, which can negatively impact sleep. Over time, a cumulative lack of restorative sleep can adversely impact not only warfighter alertness and cognition, but also metabolic, immune, and mental health.

Combining light simulation and photo-pharmaceuticals — a category of drugs that are only active in the presence of certain types of light — to target specific brain circuits, DARPA’s Alert WARfighter Enablement (AWARE) program aims to safely stimulate brain function to improve alertness for a controlled time period. The AWARE program seeks to develop a combination drug and device to non-invasively increase alertness following sleep loss in humans, without negative side effects such as anxiety, irritability, or euphoria, and with reduced addictive potential.

 

The EXACTO program set out to develop custom 'smart' .50 BMG sniper ammunition and a custom optic, to be used with existing, unmodified .50 BMG sniper rifles.

In November of 2009, DARPA awarded Lockheed Martin $12.3 million and Teledyne Scientific & Imaging $9.5 million to begin work on the new weapon.

Army Captain Keith Bell, former commander of the Army sniper school at Fort Benning, Ga., can't wait to get his hands on the new rifle. "The EXACTO would be revolutionary," he says. "It will more than double our range and probably more than double our accuracy... There's no limit as far as I can see so long as the bullet's stable — I think 2,000 or 2,500 meters is very attainable," Bell says.

In 2015, a second round of live fire tests showcased the technology and DARPA uploaded video showing fired rounds adjusting their trajectory in mid-flight to hit moving targets.

DARPA’s Extreme Accuracy Tasked Ordnance (EXACTO) program, which developed a self-steering bullet to increase hit rates for difficult, long-distance shots, completed in February its most successful round of live-fire tests to date. An experienced shooter using the technology demonstration system repeatedly hit moving and evading targets. Additionally, a novice shooter using the system for the first time hit a moving target.

The Information Processing Technology Office (IPTO) of the Defense Advanced Research Projects Agency (DARPA) is soliciting proposals to develop an ontology-based (sub)system that captures, stores, and makes accessible the flow of one person’s experience in and interactions with the world in order to support a broad spectrum of associates/assistants and other system capabilities. The objective of this "LifeLog" concept is to be able to trace the "threads" of an individual's life in terms of events, states, and relationships.

Functionally, the LifeLog (sub)system consists of three components: data capture and storage, representation and abstraction, and data access and user interface. LifeLog accepts as input a number of raw physical and transactional data streams. Through inference and reasoning, LifeLog generates multiple layers of representation at increasing levels of abstraction. The input data streams are abstracted into sequences of events and states, which are aggregated into threads and episodes to produce a timeline that constitutes an "episodic memory" for the individual. Patterns of events in the timeline support the identification of routines, relationships, and habits. Preferences, plans, goals, and other markers of intentionality are at the highest level.

Welcome to /c/DARPA - a place to aggregate the interesting and unusual research undertaken by the Defense Advanced Research Projects Agency.

While doing some personal research, I was surprised to discover how much information DARPA releases about the projects that they're working on, via their website. I thought it could be interesting to put some of the strangest projects together here.

I want this community to function well as a tidy RSS feed, so posts should be direct links to DARPA research projects from darpa.mil, or reputable news and information sources. General discussion is welcome in the stickied post. Depending on community activity, I'll make the sticky post weekly or monthly.

Posting is restricted right now, but will be opened soon, after I put together a handful of initial links.

Let me know your thoughts, and, cheers!

Biological sensors often display high sensitivity, selectivity, and low false alarm rates while being fabricated and operated in dirty, noisy natural environments. Attempts to emulate these sensors synthetically have not fully met expectations. Recent evidence suggests that some biological sensors exploit nontrivial quantum mechanical effects to produce macroscopic output signals. Examples of such sensors include the highly efficient energy transfer properties of photosynthesis in plants, bacteria, and algae; magnetic field sensing used by some birds for navigation; and the ability of some animals to detect odors at the single molecule level. The Quantum Effects in Biological Environments (QuBE) program is laying the foundation for novel sensor designs by challenging the long-held view that biological sensors utilize primarily classical physics. QuBE will verify, understand, and exploit these effects to develop new scientific foundations for sensor technologies for military applications.

 

Traumatic stress has caused a host of devastating effects for many military service members, including mental illness, substance abuse, post-traumatic stress disorder, family violence, and suicide. Since Sept. 11, 2001, more than 30,000 active duty members and veterans have taken their own lives — a tragic toll that represents four times the number of those killed in post-911 military operations.1 Developing effective approaches to prevent suicide is a top priority within the Department of Defense.

DARPA’s STRENGTHEN program, short for Strengthening Resilient Emotions and Nimble Cognition Through Engineering Neuroplasticity, aims to build on recent advances in neuroscience and clinical practice to increase well-being and prevent or mitigate the effects of traumatic stress leading to behavioral health disorders and suicidality. The program endeavors to accomplish this through enhancing cognitive flexibility (CF) and emotional regulation (ER), key behavioral health mechanisms that act as protective buffers against traumatic stress. CF refers to the mental ability to switch between thinking about two different concepts according to the context of a situation. ER is a conscious or nonconscious strategy to start, stop, or otherwise modulate the trajectory of an emotion.

STRENGTHEN will strive to enhance the mental protective mechanisms of CF and ER through two goals: (1) Development of individualized brain network models of CF and ER and (2) design of multimodal, multidimensional interventions to induce neuroplastic change in the functional connectivity and/or structure of CF and ER brain networks to optimize an individual’s CF and ER.

The Targeted Neuroplasticity Training (TNT) program supports improved, accelerated training of military personnel in multifaceted and complex tasks. The program is investigating the use of non-invasive neurotechnology in combination with training to boost the neurochemical signaling in the brain that mediates neural plasticity and facilitates long-term retention of new cognitive skills. If successful, TNT technology would apply to a wide range of defense-relevant needs, including foreign language learning, marksmanship, cryptography, target discrimination, and intelligence analysis, improving outcomes while reducing the cost and duration of the Defense Department’s extensive training regimen.

Postmedia has learned from multiple sources that McFee has told the Edmonton Police Commission of his intention to leave the job in February, after six years in the post.

He was initially hired to the role in February 2019. His current contract was set to expire in 2026.

Shortly after Postmedia’s story was published, the commission put out a news release confirming McFee’s departure on Feb. 21.
