  • Ship blocking Suez Canal will snarl constrained chip, electronics industries

    One option I read that is being considered is to offload fuel rather than containers.  It would not be enough to float the ship but it could be done fairly quickly and would help.
    They also unloaded ballast already. Water is used as ballast.

  • Apple 'AirTags' slightly larger than US half-dollar coin, says leaker

    I haven’t seen a US half dollar coin in years so I had to look it up. Didn’t know they were still in circulation. Ok. 
    They are as rare as a US 2 dollar bill. You can still find $2 bills in circulation.

    https://en.wikipedia.org/wiki/United_States_two-dollar_bill



    I have a few near perfect $2 bills from having visited Monticello in past years. At one point in the past they would give you change back from the admission price (which I seem to recall was $8) using two-dollar bills because ... Jefferson is on the two. The half dollar coin is just something I so rarely encounter that I don't have an intuitive feel for the size. For non US readers imagine that using a lesser known US coin as a size reference is kind of like saying that something has "the airspeed of an unladen swallow.

    Jokes aside, from the comments I'm seeing here am I to believe that Apple's AirTags will have geo tracking capability, as in I can see exactly where my tags are anywhere in the world at any time? Is there a GPS and active pinger in the tag? If this is true, it would far exceed the capabilities of the Tile tags, which seem to be limited to Bluetooth ranges. My understanding was that these tags have to have been reported as "lost" before they will communicate with other iPhones that happen to be within Bluetooth range of the tag. So if a tagged item is not within range of a participating iPhone they would be undetectable.
    It's fairly certain that there isn't GPS in the tag, but in effect there is, because neighboring iOS devices do have GPS, and can send the actual GPS location of the page to Apple's servers.

    Regarding your claim that the tags will have to be reported "lost" before the communicate with other iPhones. I don't think that's even mechanically possible because by definition a device that's lost can't be "told" it's lost to have it start communicating. But with a billion phones and a billion AirTags, it seems that there would be an inordinate amount of traffic being sent via other people's iPhones. I haven't figured out how much traffic there will be or whether people will be unhappy that they are getting charged for cellular data that doesn't have anything to do with them.

    Interesting. Seems like a coupla tugboats could free it, but what do Editorbs know.
    The Suez doesn't tow vessels from the shore within its confines. It's looking like there was an engineering casualty that locked the rudder, driving the vessel into the sidewall at transit speed. So, the bow dome is buried pretty deep in the sand at the edge of the canal.

    200,000 metric tons plus doesn't stop on a dime, and that's a lot of force behind it, even at just a few knots. And, in that stretch of the canal, there isn't a good way to unload the vessel.
    Blow up the ship! Don't try to preserve the ship and containers. The loss of shipping delays are much greater than this. Try to salvage the containers on the water. 
    200,000 metric tons of vessel and more mass in containers doesn't evaporate. A sunken hull will be harder to remove.
    200,000 metric tons is weight of water it expels. The ship is much lighter. 
    Three minor corrections.
    1. That 200 metric tons is the "maximum load" that the ship can carry (including fuel, ballast, crew & provisions). Normally it carries less than maximum capacity.
    2. Historically shipping was always measured in Long Tons, which are NOT metric tonnes. Metric tons should be spelled "tonnes." And Imperial (Long) Tons should be spelled with a capital "T." So "metric tons" is technically an oxymoron (it should be "metric tonnes"). However starting around 2010 the shipping industry (including the US) appears to have settled on using "metric tonnes" rather than "Imperial Tons." One has to be careful because lots of documentation (pre-2010) still refers to Imperial Tons. The difference between the two is about 10%.
    3. It's not "the weight of water it expels", it's actually "the weight of salt water it expels" which is 2.5% more weight than regular water per unit volume.

    So if you pause to think about it, a large salt water ship that enters the Panama Canal's freshwater system (or the freshwater in the St. Lawrence Seaway which begins at Quebec City) will sink (about a foot, I think) because fresh water is less dense. It just instantly sinks by a foot the moment it reaches fresh water... amazing.

    "Ever Given"?

    My eyes see "Evergreen".
    Evergreen is the name of the shipping company that leases the ship. The vessel itself is called Ever Given. There's also an Ever Gentle, an Ever Gleamy, an Ever Genius … you get the gist. 

    If you look at the small print at the end of the ship, I think it says "Ever Given".

  • The case for Apple TV -- why Apple's 'hobby' isn't as dead as critics think

    Apple is a forward-thinking company. They embrace the future, not the past. The future is online. Apple will not likely cater to the 1% of you who lack a decent online connection.

    Even if you live in a place with no high speed internet via landlines or cell towers, Musk's Starlink is now being deployed, and it costs less per month than what I'm currently paying for my high speed internet. And the first Starlink customers in Canada are getting 400 Mbps download speeds for about US$99/month. That's the same speed as typical fiber internet. So I can't see Apple catering to people who refuse to get online.
