That doesn't look like a little repair, which is what I had assumed. That looks like the ship's insurer is buying Baltimore a new bridge.

https://en.wikipedia.org/wiki/Francis_Scott_Key_Bridge_%28Baltimore%29

The main span of 1,200 feet (366 m) was the third longest span of any continuous truss in the world.

Smooth.

The bridge, at an estimated cost of $110 million

Construction of the Outer Harbor Bridge began in 1972, several years behind schedule and $33 million overbudget.

So $143 million in 1972 dollars...

https://www.usinflationcalculator.com/

$1.06 billion in 2024 dollars.

EDIT:

95k ton displacement.

https://www.imo.org/en/About/Conventions/Pages/Convention-on-Limitation-of-Liability-for-Maritime-Claims-(LLMC).aspx

Convention on Limitation of Liability for Maritime Claims (LLMC)

The Convention provides for a virtually unbreakable system of limiting liability.  Shipowners and salvors may limit their liability, except if "it is proved that the loss resulted from his personal act or omission, committed with the intent to cause such a loss, or recklessly and with knowledge that such loss would probably result".

The limit of liability for property claims for ships not exceeding 2,000 gross tonnage is 1 million SDR.

* For larger ships, the following additional amounts are used in calculating the limitation amount: 

  • For each ton from 2,001 to 30,000 tons, 400 SDR 

  • For each ton from 30,001 to 70,000 tons, 300 SDR

  • For each ton in excess of 70,000, 200 SDR

So that'd be 29,200,000 SDR.

https://www.imf.org/external/np/fin/data/rms_sdrv.aspx

1.325610 US dollars per SDR.

So about a $39 million limit on marine liability for a ship of that size, or under 4% of the price of the bridge.

Maybe Baltimore taxpayers are gonna be buying Baltimore a new bridge.

EDIT2: I wonder how owners of larger ships managed to get lower per-ton liability limits than owners of smaller ships.

EDIT3: Oh, wait. Apparently the US isn't party to that treaty. Sounds like the US uses law even more favorable to the shipowner.

https://iclg.com/practice-areas/shipping-laws-and-regulations/usa

The United States is not a party to the 1976 Convention on Limitation of Liability for Maritime Claims.  Instead, the United States continues to apply the Limitation of Liability Act (the Limitation Act), passed in 1851 to encourage investment in shipping.  Under this Act, vessel owners (including demise charterers) may limit liability to the value of the vessel and pending freight in certain circumstances where the loss occurred without the privity or knowledge of the owner.

https://en.wikipedia.org/wiki/Limitation_of_Liability_Act_of_1851

The Act was passed by Congress on March 3, 1851 to protect the maritime shipping industry; at the time, shipowners were subject to loss from events beyond their control such as storms and pirates, so the Act was designed to limit the shipowners' liability to the value of the vessel. Without it, American shipping was "at a competitive disadvantage" compared to other maritime countries where similar limitations applied.[1]: 260 

Section 3 of the 1851 Act states "the liability of the owner or owners of any ship or vessel ... shall in no case exceed the amount or value of the interest of such owner or owners respectively, in such ship or vessel, and her freight then pending".

I guess if you're gonna knock down a bridge with a container ship, the US is probably a good place to do it.

“Going forward, it is mandatory in North America to install and activate FSD V12.3.1 and take customers on a short test ride before handing over the car,” Musk wrote in an email to staffers on Monday. “Almost no one actually realizes how well (supervised) FSD actually works. I know this will slow down the delivery process, but it is nonetheless a hard requirement.”

I mean, you can require the employee delivering the car to offer to take the customer on a ride. You can require the employee to tell the customer how awesome the service is. But I don't see how you can make the customer go for a ride if the customer doesn't want to go for a ride. And, frankly, I kind of suspect that a not-inconsiderable number of new customers just want to go use their new car and aren't interested in sitting through a sales pitch for some associated service.

I'm not building a PC at the moment, but this drove me nuts last time I got a laptop, and I've been wondering if anyone else has ideas along these lines.

I'd like to have a laptop that:

  • Has a 100 Wh battery (100 Wh being the largest allowed on airplanes, so generally the limit on what one can get). I don't mind the weight or the cost, but recently it's been increasingly-difficult to find 100 Wh laptops. The laptops that do tend to be heavy power consumers; they're aimed not at providing a long battery life, but managing to keep a gaming laptop running for a short period of time.

  • I'd very much like to have a Thinkpad-style trackpad, with three mechanical buttons. I don't care about the "nipple mouse" on Thinkpads. Synaptics makes these, but laptops with them are quite difficult to find these days.

  • Is as upgradable as possible. I'd rather not pay an exorbitant amount to have a large amount of memory and NVMe on the thing.

  • I don't really care about heavy weight or large size (at least within the kind of weight classes that laptops have).

  • I would like to have a centered keyboard, though, if the laptop is large. I don't use a numeric keypad (I have an external USB one that I can use for the very rare times that I want to use something where it's actually useful), and many larger laptops (which often have larger batteries) de-center the keyboard and stick a numeric keypad on the side.

  • I generally favor vertical screen space (i.e. for reading documents and webpages rather than watching movies). 16:10 ratio is preferable to 16:9, and I'd take more-vertical ratios if they were available.

  • It'd be nice to have so much lower bezel below the monitor that I could lie down and use the thing on my chest without my hands obstructing the view of the screen.

  • I'd use Linux on it. At least with major vendors, compatibility isn't really an issue these days, but it's something that I do keep in mind.

  • It's not vital that I have discrete video hardware, but if I do, I'd rather go with AMD hardware rather than NVIDIA, as AMD is more Linux-friendly.

  • I'd slightly-favor not getting something out of China, though that's not a must-have.

  • Having a fair number of USB C ports -- which I expect to use more of moving forward -- is nice, as is rapid charging.

  • I'd rather not have "gamer-style" aesthetics with LEDs and a ton of decorative plastic molding all over the thing.

  • I can live with an unimpressive integrated camera, though I do use the thing occasionally.

  • I don't mind doing some work on this, like spodging open a laptop to upgrade non-soldered memory and NMVe, but I don't really want to go to the degree of 3d-printing a laptop case or something like that myself.

  • I'd be willing to get a thicker laptop.

  • I'd slightly favor having fan vents on the side rather than bottom, so that if I put the laptop on my chest, I'm not blocking said vents. That being said, that's a hard ask these days with thin laptops and wanting to have a fair number of ports on the side.

  • I'd like to have a wired Ethernet port, but I can live without it; a USB adapter would be okay.

  • I'm not rabid about display brightness, but I've generally found that Thinkpads have a weak-enough backlight that it can be annoying, even at maximum power. OLED would be nice.

  • I don't mind paying somewhat-more for a laptop like that, but I'd prefer to not go more than several hundred extra, not several thousand.

Some things that I've looked at that hit at least some of these:

  • Thinkpad T-series. This is what I'm using now; I've used and been relatively-happy with Thinkpads in the past. I'm generally happy with the aesthetics. It ticks the "Synaptics trackpad" box. Lenovo has no option for a large battery (my T14 has a 57 Wh battery) (whereas Thinkpads used to have available externally-accessible batteries that would extend beyond the bounds of the case; some even had a smaller backup internal battery and let a user hot-swap the larger batteries). At least on the T-series laptop I have, the components are not soldered and I had no problems spodging the thing open and upgrading them. Charging speed is okay, but isn't mind-blowing. Bottom air vents. It's out of China these days. Has a decent amount of bottom bezel, but not enough that I can lie down without my hands obstructing the screen. In general, I'd rather have a heavier/thicker laptop with a longer battery life than is the case for these today.

  • Framework laptop. These are one of the few laptops that permit one to increase the number of USB C ports. They also have the option to get a large laptop with a centered keyboard. They don't provide an option to have a user-replaceable trackpad, unfortunately, so no Synaptics trackpad, and they don't provide another option for mechanical trackpad buttons. These only go up to 61 Wh battery. They specifically target working out-of-box with the base Linux kernel, no third-party drivers.

  • Tuxedo Computers's InfinityBook. These guys make a 14-inch-display laptop with a 99 Wh battery, which is an uncommon combination. No three mechanical trackpad buttons, no AMD video. They don't extort one on hardware upgrades, though they do have a relatively-high base price. Good Linux support, as they ship with various Linux distros.

Any laptop can have the battery situation mitigated by hauling around a USB-C powerstation, which is what I do today and I suspect why laptop manufacturers are willing to scrimp on internal battery. Maybe I could set up something to disable charging unless the internal battery is low if a power station is connected...not sure if it's possible to detect that, whether there are power stations that also communicate with the host. But I'd rather have a larger internal battery.

To solve the "hands obstructing screen when using laptop when lying down" issue, I did try picking up a head-mounted display, a used Royole Moon. This was not satisfactory; it took a lot of twitchy setup for each use, I found that it tended to fog up, it placed what I found to be uncomfortable pressure on one's nose, and I found that if the screen wasn't exactly right, parts of the display would appear to be out-of-focus. It also completely cuts one off from the world, which is fine for some of my use, though not a solution all the time. I don't think that head-mounted displays are really a replacement for traditional monitors yet.

  • Don't use a laptop at all, and just use a luggable PC, maybe in a backpack or suitcase, microATX or mini-ITX with some kind of power station. External portable monitor. This opens up an enormous number of options; I can use any USB trackpad (or even other input device) and keyboard. My battery problems go away, because I can choose the size and charging speed of the powerstation backing it, could have hundreds of watt-hours. I don't need to worry about blocking the vents. Graphics options -- lots of portable OLED monitors -- and upgrading the thing are good. The option is available to put the display on a stand in front of the keyboard if I'm using it with it sitting on my chest when lying down, which probably isn't going to be an option with a laptop. However, there are also a number of downsides; it means that the components probably aren't as focused on low power usage or dealing well with hibernation unless I want to do the investigation work that laptop vendors already will have. Less-portable and has more setup time; one probably wants to put at least a USB hub, portable monitor, keyboard, trackpad/trackball, and maybe WiFi receiver on the table/desk when being used. No "lid switch" to auto-suspend, though I expect that I can rig something up to do that or just reconfigure the power button, if all else fails. Powerstations don't normally have a way to report remaining battery charge (though some UPSes do over USB, it's not treated as a "battery"), which is unfortunate, as one doesn't get things like a "time remaining" estimate onscreen.

Anyone else been in a similar situation and wanted something along those lines, has had ideas or done research?

No flying machine will ever reach New York from Paris.

Interestingly, when he wrote that, it was part of a larger quote saying virtually the same thing that you are, just over a century ago:

Wilbur in the Cairo, Illinois, Bulletin, March 25, 1909

No airship will ever fly from New York to Paris. That seems to me to be impossible. What limits the flight is the motor. No known motor can run at the requisite speed for four days without stopping, and you can’t be sure of finding the proper winds for soaring. The airship will always be a special messenger, never a load-carrier. But the history of civilization has usually shown that every new invention has brought in its train new needs it can satisfy, and so what the airship will eventually be used for is probably what we can least predict at the present.

In the late 1970s, H&K partnered with Hensoldt to create the ZP/AP (Ziel/Aiming; Projektor/Projector) and then ZPP/APP (Ziel/Aiming; Punkt/Point; Projektor/Projector). This was essentially a calibrated flashlight with an aiming point and pressure switch. It projected a beam of light that was specifically 2m wide at 50m distance, with a black spot in the center which would measure 30cm at 50m. This could be focused and zeroed o the black spot was a functional aiming point, allowing both target identification and engagement...

A very similar concept was used in the by the British Special Air Service most famously during the 1980 Iranian Embassy Siege. Instead of the ZPP their MP5s where fitted with Maglite D-cell flashlights on top however.

I think that the article is kind of blowing the statement a bit out of proportion.

Nobody has ever said that Ukraine -- which is at war -- does not have the legal right to hit targets inside Russia.

The issues are just diplomatic, not legal. Some countries don't want the weapons they supply being used to hit targets in Russia. Ukraine has been hitting targets in Russia for some time with her own weapons.

I don't think that this will change what Ukraine is doing, nor that it represents a change in the diplomatic positions of those countries.

https://www.marketplace.org/2024/01/29/why-credit-card-debt-rising-again/

Another reason credit card debt has been rising is because of the strong job market.

That’s because people with jobs feel comfortable spending money on their credit cards, said Liz Ann Sonders, chief investment strategist at Charles Schwab — a Marketplace underwriter.

Hmm. I would have guessed the opposite -- that you borrow if forced to in an emergency like a job loss, but if you have income, then you don't need to take out debt. Apparently that's not what humans actually do.

There's a lot of detailing what the author did to try to investigate the issues. That's interesting, but if one just wants what he found, one can skip to the end, which summarizes the results:

So why is Cities: Skylines 2 so incredibly heavy on the GPU? The short answer is that the game is throwing so much unnecessary geometry at the graphics card that the game manages to be largely limited by the available rasterization performance. The cause for unnecessary geometry is both the lack of simplified LOD variants for many of the game’s meshes, as well as the simplistic and seemingly untuned culling implementation. And the reason why the game has its own culling implementation instead of using Unity’s built in solution (which should at least in theory be much more advanced) is because Colossal Order had to implement quite a lot of the graphics side themselves because Unity’s integration between DOTS and HDRP is still very much a work in progress and arguably unsuitable for most actual games. Similarly Unity’s virtual texturing solution remains eternally in beta, so CO had to implement their own solution for that too, which still has some teething issues.

Here’s what I think that happened (a.k.a this is speculation): Colossal Order took a gamble on Unity’s new and shiny tech, and in some ways it paid off massively and in others it caused them a lot of headache. This is not a rare situation in software development and is something I’ve experienced myself as well in my dayjob as a web-leaning developer. They chose DOTS as the architecture to fix the CPU bottlenecks their previous game suffered from and to increase the scale & depth of the simulation, and largely succeeded on that front. CO started the game when DOTS was still experimental, and it probably came as a surprise how much they had to implement themselves even when DOTS was officially considered production ready. I wouldn’t be surprised if they started the game with Entities Graphics but then had to pivot to custom solutions for culling, skeletal animation, texture streaming and so on when they realized Unity’s official solution was not going to cut it. Ultimately the game had to be released too early when these systems were still unpolished, likely due to financial and / or publisher pressure. None of these technical issues were news for the developers on release day, and I don’t believe their claim that the game was intended to target 30 FPS from the beginning — no purebred PC game has done that since the early 2000s, and the graphical fidelity doesn’t justify it.

In even shorter form:

  • Highly-detailed models coupled with a lack of lower-level-of-detail models for viewing at a distance.

  • Limited culling (avoiding drawing things that aren't actually visible onscreen).

  • Some gambles made on external work-in-progress software that turned out not to be ready at release time, forcing the developer to implement their own solutions.

Literally the single prominent technical problem that has spanned Reddit's entire life is the lack of a decent search engine. In general, people fell back to Google because Reddit's was abysmal.

So is Reddit gonna finally build something decent? Because if they don't let Google index them, and they disabled Pushshift access, it's gonna be hard to search the content.
