Video comparing P320 to Glock internal safeties: (https://youtu.be/dLm23zJGSL0)
Note: it does appear that P320 has a more robust internal safety design than the P365.
I don’t know if the Sig P320 has a similar firing pin safety design to the P365, but I optioned to go with Springfield Hellcat vs P365 specifically because the Hellcat has two separate safety catch points on the firing pin assembly, thereby eliminating a single point of failure, while the P365 essentially has one (see photos here https://www.reddit.com/r/gunsmithing/comments/f7dgnl/how_saf...). Glock has also has a redundant “two-catch” internal safety design, and has a well established safety record (hellcat just worked better for my needs; glock was an equally good choice from a safety standpoint). It’s common in the US to carry in “ready” configuration (barrel loaded); IMO if you choose to do this, a single point of failure is unacceptable. It’s why hammer fire (with hammer disengaged requiring initial DA trigger pull to push hammer back) can be safer; you can also cover the hammer with thumb while drawing and feel if the trigger is accidentally engaging, helping to prevent a negligent discharge.
Interesting; just went down a rabbit hole on LLM training and math. For this example, it could have simply copied a table from online, but I wasn’t aware how poorly some LLMs perform on even basic math functions. I’ve not run into that issue before.
Towing companies (and some apartment complexes) are essentially just organized crime. An apartment complex I lived in instituted a convoluted parking system utilizing colored mirror hang tags. Each unit received one exclusive parking spot (required to display a red tag only), and the remaining parking was first come first serve (but must display a yellow tag). There was never enough free parking, and tenants routinely parked overnight in fire lanes. My partner and I worked opposite shifts, so we usually only needed our designated spot, but sometimes were unable to swap tags due to schedules. Tow companies would roam the complex at night (let in through the gate by security), and haul off any vehicle without a red tag in designated spots, while ignoring vehicles in fire lanes and other no parking zones. The first time it happened, I thought my car had been stolen (why would I even think it was towed? I didn’t call to have someone removed from my own parking spot). I only found out after contacting apartment management for surveillance video. After the second time this happened (I’m a slow learner), I trudged over to the office, walking past several cars parked in the fire lane that had been there overnight. The manager stuck to their guns, stating that rules were rules, and I had broken them. I helpfully pointed out the vehicles still in the fire lane just outside the door, and asked if I should just leave my designated spot unoccupied and take up a free space (thereby using up two spaces) just to “follow the rules.” They had the gall to say it wasn’t fair to tow the fire lane violators, since there wasn’t enough parking for everyone. So it made more sense for them to endanger tenants lives. The ludicrousness of the situation made me suspicious that the apartment employees were getting kickbacks from the towing companies. It was the only scenario that made sense, other than mass idiocy.
A few months ago I asked CGPT to create a max operating depth table for scuba diving based on various PPO2 limits and EAN gas profiles, just to test it on something I know (its a trivially easy calculation; and the formula is readily available online). It got it wrong…multiple times…even after correction and supplying the correct formula, the table was still repeatedly wrong (it did finally output a correct table). I just tried it again, with the same result. Obviously not something I would stake my life on anyway, but if it’s getting something so trivial wrong, I’m not inclined to trust it on more complex topics.
I enjoyed reading the book ‘Hannibal’ by Philip Freeman. It has some descriptions of the political climates of Rome and Carthage during the second punic war.
I’m not sure what they meant, so tbh I probably just wouldn’t have replied. You made a good point that for someone in the US (or any other country that hasn’t experienced modern war), unexploded ordinance isn’t even on their risk radar, despite the US being a major contributor to the problem. It’s unfortunate how many people continue to face that reality.
Hey, you may have not intended it, but your response comes across with a bit of a condescending tone. Please help promote HN as a place for continued civil discourse.
There are wide safety margins in diving. Most dive trips involve multiple dives per day (starting with deepest dive first, with subsequent dives shallower). The times I’ve gone deeper or same depth on subsequent dives my computer usually puts me into deco fairly quickly. At some point subsequent dives aren’t feasible (typically no more than 4-5/day, less is prudent). I think it is with this in mind that the recommendation against flying is made, along with an abundance of caution due to limited experimental evidence (Navy dive tables were developed based on human subjects, so the effects are better understood). It looks like there are some civilian studies done, but more is needed on flying.
There is also an increased risk of decompression illness simply because passenger aircraft typically maintain a lower atmospheric cabin pressure (US federal limits pressure equivalent to 8,000 ft elevation). Going from a high pressure environment (underwater) to a low pressure environment (8,000 ft equivalent elevation in aircraft cabin) too quickly can also cause the bends. Dive computers use algorithms to calculate when it is safe to fly post-dive.
To further expound on why snorkeling and freediving after scuba can be dangerous, it is helpful to understand that the greatest gas compression occurs in the first 10 meters underwater (Boyle’s law). Scuba divers are trained to ascend slowly (~10m/minute) in order to off-gas expanding nitrogen (and other gasses) and prevent bubbles from forming in tissue (which causes decompression illness). After scuba diving the human body still has a much higher residual nitrogen saturation, so even fairly shallow (less than 10m) rapid descents/ascents in the water column can cause bubbles to form.
Also a diver here. There are generally different biological mechanisms involved for “free diving blackout” vs “hypoxic blackout” (which is related to exertion while breathholding). Freedivers train to relax muscles and stay calm, so blackouts due to pressure changes are more common rather than to exertion. Swimming horizontally under water requires a lot of effort, which burns more oxygen. Combine high exertion with untrained individuals not aware of the risk, or misuse of hyperventilation (which doesn’t increase oxygen, but decreases CO2), and suppressing urge to breath, and you can also blackout.
As someone who recently bought a house (and used to live in an apartment), those were some of the reasons why I opted out of apartment life. I would prefer to live in a denser urban area if other amenities and quality of life benefits came with it, but they don’t in my city. Even if you live close to the city core, there are either extremely limited or entirely nonexistent options for groceries, fitness and recreation, coffee shops, affordable eateries, non-alcohol entertainment and art, etc in most neighborhoods. You would still have to drive most of the time anyway. Most of the denser areas closer to downtown can also be quite dangerous for pedestrians after dark. The few places that have denser housing with those amenities within (safe) walking access are exorbitantly more expensive. Meanwhile apartment and townhome developments are now springing up everywhere in my area of town, but without any amenities to go with them, leading to even more vehicle congestion on the local streets as people try to escape the neighborhood and reach the highways.
This reminds me of a time I was stargazing, when suddenly a meteor streaked overhead making a distinct sizzling/hissing sound that tracked with its movement…which seemed improbable since light obviously travels faster than sound. I later read the theory as to how this phenomenon occurs is that the sound is created by low frequency radio waves.
Based on historical averages, none of these cities are hotter than Houston. They might have more humidity, but Houston averages are higher AND regularly experiences sustained daily highs during summer in excess of 100°F/38°C.
This is what is happening in the US city I reside in. Developers are gobbling up land and putting in “high density” housing, but without building any additional amenities or restructuring roads that make the area more enjoyable to live in. And this is in a city with very libertine zoning rules, so mixed use is not restricted. The price/foot is about the same for the higher density housing as it is for a house and a yard just a 10-20 min drive further out, so given the choice between high density/no amenities/no parking/not walkable/surrounded by high speed roads vs a house with a yard and a garage (will have to drive in either scenario)…I’ll take the bigger house and the yard.
As someone in the US who has lived in small/er towns for over half my life and now lives in a major metro area, the benefits of denser urban areas greatly outweigh smaller towns at this stage in my life. Outside of the western states, much of the US is private land, so outdoor recreational opportunities are limited even in rural areas. In my personal experience quality local entertainment and dining has not increased in small towns, if anything its gone down as more people source entertainment online and big corporate chain restaurants take over real estate. In my experience denser urban areas have more to offer in terms of diversity of art, culture, and thought. Economies of scale make it possible to sustain niche endeavors. Access to international airports is also a major boon.
I was a relative early adopter of smartphones, and have used one for most of my adult life (since university). For me it is an incredibly useful and almost irreplaceable daily tool:
- photography and audio recording
- note taking
- maps/navigation/compass
- email
- file management
- messaging/audio communication
- tickets and traveling
- language translation (does anyone have a recommendations for a less privacy invasive tool similar to Google Lens translation?)
- calculators
- emergency flashlight
- fitness and health tracking
- time keeping/alarms/timers
- weather
- quickly looking up information online
- reminders/calendars and task management
- books (both text and audio)
- music storage and playback
- banking/finance/payments
- passwords and token management is far more convenient
I’m also on call for work 24/7, so quickly having access to employer’s and customer’s communication service, software, and files is a requirement.
All of these tasks could be completed using multiple different tools, but with immensely greater friction and difficulty. It amplifies and augments mental capabilities.
The downsides as I see them so far:
- Constant access to data, distractions, news, communication reduces ability to focus and can create mental fatigue (but I already had issues with focusing anyway, so the benefits of time management outweigh the cons)
- Social media…enough said
- probably reduces memory and mental capacity as its easier to simply look something up or run a quick calculation than to remember data or do mental math. So while it can augment mental capacity, it can also become a crutch. Like every new technology there are both benefits and cons. It requires leveraging the new technology in a way that benefits you, and mitigating or managing any negative impacts.
With family roots in ranching, one of the concerns with freedom to roam in the US for landowners (in particular for land used for livestock and agriculture) is a lack of respect for others/natural resources. Existing public use areas in the US already regularly get trashed in some parts of the country by those who fail to practice leave-no-trace. And my family has had existing issues with poachers and trespassers cutting fences, leaving gates open (which becomes a liability when livestock enter roads), and even shooting livestock. I personally like the idea of FTR, but putting on my ranching hat to see from that perspective, we might need additional legal protections to protect landowners from damages and liability.
I work on sales/customer facing side of a non-tech industry, but my experience has been different than root comment. My industry is engineer/finance driven, with sales as more of an afterthought or necessary evil. I try to stay tied in with the development/production side as much as possible for sales, but the mismanagement and culture rot on the development/production side has me looking for a new job as it spreads through the company. It’s tough seeing top performers leave/forced out and petty politics and mismanagement take over. It makes my job much harder. The rot has eventually trickled down to other departments, so I think it’s time to make an exit.
This seems to be the trend in US business culture as a whole. I work in a more industrial sector, but the same problems persist: Repeated management turnover and restructuring. Despite top performer reviews, withholding promotions and raises. Under hire/over work personnel (“we run lean here”). Preach cost cutting on public side with the need for layoffs, all while hosting extravagant trips and dinners for upper management behind closed doors. Petty department politics and nepotism.
It’s hard not to become jaded, since this has been the eventual outcome at last two employers (even if they didn’t start out that way, the rot set in). Trying to find a healthier place to work, without sacrificing career growth.
Interesting…I have had the opposite experience. Apple maps has recently been much better at providing more complete results for searches (gyms, restaurants, retail, etc.), while still lagging behind Google for driving directions and traffic. Google maps appears to be excluding relevant results from searches (which appear in Apple maps), and instead offering up promoted locations.
I worked unskilled manual labor jobs (ranching/landscaping/construction/roughnecking/etc.) in the southern US starting age 14 during high school, then through university to pay for tuition (sometimes working two jobs), and after university in the oilfields until I finally found a white collar job utilizing my degree. It is back breaking work, sometimes in 100°+ heat/12 hr days, typically with zero health benefits. Many times employers are happy to use people up. The chance of injury is high, and even in skilled trades the longterm career sustainability is tough and hard on the body. It is also sometimes a culturally abrasive/toxic work environment, with hazing and poor leadership. I quickly decided that was not the life I wanted, and leveraged my degree into something else. I think that in the US some of the primary reasons people leave or avoid blue collar/hard hat industries is due to the risk of injury and poor quality/nonexistent or unaffordable healthcare.
I was lucky to learn how to ride from someone with decades of experience. Was taught early on to always prepare for the worst to happen, and one of the best ways to avoid an accident was to avoid it altogether (i.e. taking the longer/safer route around a congested city, don’t ride after dark (avoid wildlife), etc.). Its important recognize “normalization of risk” bias. Because the natural consequences of failure on a motorcycle can be so severe, its not adequate to use personal failure as a metric for riding behavior. You can always push the limits a bit further…until you cant anymore. I only crashed once…lowsided on a routine evening ride where road construction crew had left a 3” tall 90° angle curb between 2 uneven lanes. Didn’t see it in time while switching lanes. Should have been easily avoidable. A rider is fully responsible for their ride profile, no matter the conditions. Just a few lessons learned from years of riding over thousands of miles across North America. I now live in a city that I consider to be too dangerous to ride in (high speeds and driving culture has a reckless disregard for traffic laws). Thinking of picking up off-road riding again, since it fits better with my current lifestyle and hobbies.
