More junk in the ocean.

Read the Wikipedia article. This happened in 2011, as of 2014 77% of the containers had been salvaged, a lot of the ship removed, and they were still working on it.

Simple weight transfer - the driver needed to brake hard, then added steering input for reasons unknown. Weight and therefore grip is transferred to the front tyres away from the rear tyres leading to oversteer, and while this sub seems to have an obsession with traction control, that wouldn't have helped. ESC (electronic stability control), might have helped if equipped, but at the end of the day this is a big and very heavy car and Physics > Electronics. Even electronic intervention has its limits.

They are cameras, for watching the highway. Your state may even have a web page for you to be able to view them. At least Pennsylvania does. In PA they are connected through a buried fiber network. There were a lot of articles about it at the time, the state let some company run fiber for itself along the highways at no charge as long as the state got to use some of the capacity for the cameras.

Not Ayrton Senna??

I would never claim this list to be conclusive, there might be more I missed and I'm happy to hear other peoples takes.

That said, Senna deserves to be mentioned as one of the greatest F1 drivers of all time, but he was never seemingly unbeatable for a prolonged period, was he? Definitely worth a discussion, though.

Well, Schumacher said Senna was best, so there is that. So did a lot of other top drivers. But Senna's career was cut short, so we will never know what records he might have set. I suspect Senna's percentage of pole positions over his 10 years in F1 is unmatched (80 out of 162), but I don't feel like doing the research on other drivers to make sure. Senna had an amazing ability to drive a F1 car on the edge, and just a little bit past it.

I probably would want to list Fangio, Senna and Schumacher together, and then everyone else, at least for F1.

And don't forget Don Garlits in drag racing. Very popular, had a lot of firsts, perfected the rear-engine dragster.

Sébastien Loeb won the WRC championship nine times in a row during his 14 year career in WRC, most event wins (78 out of 171), most podium finishes (116) and most stage wins (912).

Smartphones can be wiretapped?

Yes, cell phones can be wiretapped. They just tell the phone companies to forward everything for that number. They don't need to capture the wireless part just to hear the conversations when they know the phone number.

In the USA, being able to wiretap any phone call is required by law: https://en.wikipedia.org/wiki/Communications_Assistance_for_Law_Enforcement_Act

IMSI-Catchers aka Stingray are used for real time localized tracking, interception and spoofing. This are different goals than "wiretapping". A FBI agent sitting in Washington DC can initiate a wiretap on a phone in California. IMSI-Catchers have to be within the cell tower range of the target phone, and obviously do not work on land lines or VoIP calls.

Edit: Also, a wiretap will follow a moving cell phone, that is quite difficult for a IMSI-catcher (but not impossible). A wiretap will capture a "WiFi calling" connection if it goes through a CALEA-compliant carrier since the call is still routed though the regular phone network.

It’s the same technology as 30 years ago,

No, there was a huge change in technology from the original analog cell system to the current digital cell system. Yea, sure, it is still RF based but pretty much everything changed. That is why the original analog cell phones stopped working when the carriers shut down the analog tower network.

Why should the railroad shut down a major line, regrade a half mile either side of the bridge, re-install a mile of rail, and then install a bridge ? They already fixed the problem for themselves by putting a large steel beam ahead of the bridge. Drive around the East Coast some, low bridges are common. Drivers need to pay attention.

They are C-band satellite dishes, so depends on who your neighbors are. They are used to receive commercial satellite broadcasts. So if your neighbor is a tv or radio station they are receiving their Network feed through them. If it is a hotel, then they receive different (bundles) of channels through each dish and combine them themselves for like their own cable TV system to send to rooms. If a large corporation then they can receive leased video feeds through them. If that's the tallest building in town then the tv station migh not be located there just leases the rooftop space.

see more

Not just TV, it could be anything. A company in the last building I worked in had 4 dishes outside, they received weather feeds from various satellites. They processed the data and sold weather forecast products to cities, mega farms, etc, over the Internet. They had a relatively small amount of office space, less than 10 people and a server room. They had connections to four ISPs, we didn't have to pay much to add redundant connections because multiple ISPs were already in the building.

There is a regulator on every gas meter at each home. Why didn't the regulators restrict the output pressure? The regulator on the meter and gas valves on each appliance would have to of failed at each home that had a leak?

Not on all gas systems. Not on this gas system. This system ran the street pipes at 1/2 PSI, and no regulators in the home. This is not a unique setup. The distribution system runs at 75 PSI. Local pressure regulators reduce this to 1/2 PSI for the street pipes.

The NTSB has inspected one of the local pressure regulators. The downstream pressure sensor pipe (yes, pipe) to the redundant regulators was connected to a capped off pipe. So the regulator ran full open trying to pressurize a pipe it wasn't even connected to. The pipe was capped off because of construction and/or upgrades.

Source: NTSB briefings on youtube.

Makes zero sense. If the pipe is capped off, it is building pressure because it can't escape

2 points · 2 days ago · edited 2 days ago

The implication is that it was capped off at the source end - not connected to the supply. No path from the regulator to the capped off pipe. This was because the pipe was involved in construction/upgrades. They were talking about the pipe configuration in the regulator vault, not anywhere else. Go watch the NTSB video. I really doubt the NTSB is wrong about factual information gathered at the scene.

Traction control and Stability control are separate though in most sports cars for the last decade or so depending on brand. Traction control detects wheel spin, stability control detects the car yawing at a greater rate than the steering input should be providing. In other words, this guy wasn't using launch control, he's just an idiot that turned off all of the nannies.

The recent AMGs I have seen have a single button for "ESP" which is both stability and traction control. It has three settings - Normal, Sport and Off. Sport mode reduces both traction and stability assistance, but both stay on. Off turns off both stability and traction control. To use launch control ESP has to be in Sport mode, not off.

super cheap ones.

Just try to use one that has a UL Approved sticker.

Worked in a large data center, vendors always included useless power cords like this, even when we checked the "no power cord" box on the configuration forms (you use a different kind of cord in a rack with PDUs). They accumulated in those roll-around dumpsters used to collect trash in office buildings. They sent 3-4 bins full to the copper recycler every once in a while, it helped pay for employee cook-outs.

Never seem to be able to find one at home when I need one.

I may sound like an idiot here, but is it common for them to explode like in the movies if they're on fire? I imagine all that heat and fire igniting the gas tank or something

see more
13 points · 3 days ago · edited 3 days ago

A tank of gasoline generally will not explode, there isn't enough oxygen. And what oxygen there is is only in contact with the surface. Hollywood uses many different methods to spread gasoline or diesel or kerosene in the air and then ignite it to get the big "explosions". That is much simplified, there are many "making of" videos that explain it in more detail.

There are many things in vehicles that will make small dangerous explosions - the tires, airbags, bumper and suspension shock absorbers, hood/hatchback/trunk struts, things like that. The struts can shoot spear-like projectiles with a lot of force. Watch out for the bumpers as well. So yes, don't stand near a burning vehicle.

If the fuel is leaking and spreading on the ground, it could ignite all at once into a big cloud of fire. Then you can have an argument about whether or not it was an "explosion" or not.

There are many car fire videos on youtube that show all these various small explosions. I saw one where a hatchback strut shot out and broke a large store window 10 feet away.

Ah okay thanks. What if in a big collision - the fuel tank completely "shatters"? Maybe a fire like this in a different position could melt the tank and eventually make contact with the gasoline. There has to be failsafes right?

see more

Maybe I should have said an intact gas tank generally will not explode. The more oxygen in contact with fuel, for whatever reason, the greater chance of explosion there is.

The only fail safe against a leak spreading would be a race car style fuel cell. And the intent of those is only to provide time for rescue/escape, not to completely prevent leakage. If the fuel leaks out and spreads, and comes in contact with an ignition source, it will go up in a large fireball.

Don't approach any fire unless you know what you are doing. If you feel you must to rescue someone then good luck.

I've been reading a lot about air disasters recently. And if anything stands out to me it's that 1) It's a lot of little errors that eventually route you to catastrophe, and 2) There are usually multiple failures in personnel operating procedures, i.e. more than one person is not doing what they should be doing.

With Helios 552, the technician fucked up, then the pilots fucked up more than once (ignoring the altitude alarm, ignoring the deployment of the passenger oxygen masks, and not realizing the signs of their own hypoxia), also the flight attendant slightly fucked up by not checking on the pilots earlier...that attendant was commercially licensed for crying out loud. You'd think they'd want to know what's going on, see if they could help.

If anybody want to read about another case of a "symphony of errors", check out Air France 447.

I can think of a few solutions off the top of my head that would mitigate the problem better, that are considered just good seamanship.

Baffles in the hold of bulkers Is never going to happen to be honest, the companies would consider present losses an acceptable risk, compared to the difficulties having divisions in the hold would cause, so we have to look at other solutions.

For me, tanks, or hold should be full, if not, it’s a known risk that needs to be monitored, current ship has dump doors, so any problems we can remotely just dump the cargo at sea, and drainer pumps, always drain the cargo.

I had Anixter make up a couple like that for a mainframe that had something like 24 NICs in a very packed rack. The sleeving ran back a good 20 feet into the floor. We knew we were going to need to move the rack at least once and the scheduling was very tight. This let us move and route the bundle when needed in the middle of the night instead of having to pay overtime for a cabling contractor. The sleeving kept other things from getting tangled with the bundle.

You mean like a properly managed and secured bundle would?

That doesn't work well in a high change rate environment. And by change rate, I mean entire racks arriving, leaving and being moved two tiles or 100 feet away. This was a demo lab, catering to customers wanting specific equipment configured specific ways so they could bring their existing workloads and run them on new systems before signing multi-million dollar agreements. Appearance mattered, having the equipment the customer was using in the front row mattered, even if that meant completely changing out the front row over a weekend. Everything was under the floor, ladder racks can't be made to look decent enough, especially with a high change rate. It was a very, very different world than a production shop.

They measure to be able to plan. They need to know traffic volume, and how it is changing over time, to be able to decide on road maintenance and improvements, down to the types and thickness of the pavement.

Back when most gas stations were full service and had air hoses across the entrances to ring a bell to call the attendant, a lot more people seemed to understand them.

I agree. The good thing is extra steps can be taken to prevent those things. Current incidents, like driving while high, may be case by case, but the grand total is startling. Tens of thousands of deaths each year with hundreds of thousands of injuries each year along with that - guaranteed deaths, vs a software problem that might result in a malfunction that could result in an accident. Another benefit? Say there is an update rolled out - if there is a sweep of incidents, an alert could be automatically triggered to prevent further incidents until a review is made. This could theoretically limit the danger from a catastrophic number to just a few.

The thing is that it isn't clear what those extra steps are. Proving the correctness (or even testing that it is close to correct) on this scale of complexity and danger to the general public is somewhat new.

There's got to be some trust, e.g. trust the company they'll test their own new software else they could get sued by owners.

There's the same problem in the field of medical devices, how do you regulate software (e.g. a smart insulin pump), especially when machine learning is involved? You're not going to ask companies to do clinical trials every time the software is updated.

There's the same problem in the field of medical devices, how do you regulate software (e.g. a smart insulin pump), especially when machine learning is involved? You're not going to ask companies to do clinical trials every time the software is updated.

First, the trust issue: Tesla shipped Model 3 cars with a bug in the software that occasionally resulted in longer braking distances. The problem was found by Consumer Reports, not Tesla. And this wasn't even part of any self-driving feature. Then they pushed an update to all the cars something like 3 weeks later to fix this? How much regression testing could they have done? Having worked in software QA for many years, I have concerns about Tesla's software practices. There are many red flags. There might not be problems, but evidence so far suggests there is.

Second, the FDA, FAA, DoD and other agencies do have rules, regulations and laws about software development and modification. They control how much testing is required and re-certification is needed when changes are made to software. Similar requirements will be needed for cars.

This is the first thing I can think of that will have such complex software in everyday hands that has the potential to kill not just the operator, but other people in the vicinity. New ideas about software reliability and correctness, and how to ensure them will be needed.

Edit: There are many complaints about Windows Updates breaking things. Tesla is pushing updates nearly as fast as Microsoft, if not faster.

What you are looking for is called a "caching proxy" and other names. It doesn't work for HTTPS (encrypted) content unless you manipulate the security certificates on all of the clients to allow a "Man in the Middle" to see all content. This breaks security provided by HTTPS, at least within your network.

Remember that with HTTPS and other encryption nobody in the path of the request or reply can see the details of the data. Which makes it impossible to cache.
