<p>It must depend on what you’re using to read it. It’s also readable for me on an OLED iPad, and gives me ideas about what I actually want when I wish I could turn the contrast <i>down</i> while reading it with low ambient light.<p>Bringing the brightness levels of the background and text closer together doesn’t ever seem to work, but being able to add a slight blurry dropshadow behind behind each character might be a way to reduce the artifacts OLEDs seem to create when my eyes are tired.</p>

<p>There’s also a strategy to jump the line. Say there’s a talk that just took place on the top floor roof deck of a small ~20 floor building. People who don’t want to wait in line with a hundred people, can take the stairs down one level, call the elevator on the way <i>up</i> to enter the car before it is filled, ride it up one level*, and then ride it all the way down to the ground floor.<p>To prevent a riot, the building should probably deploy an employee with a fire key to manually operate the elevator.<p>* Elevators will answer an up button call while it is going to meet a down call from the top floor, but they will answer that call before filling any new down instructions, so you do have to ride to the top first.</p>

<p>Maybe it looks more amazing in person than in pictures. If not, and the point is a message about waste, then the 80% increase could be cast as part of the message.<p>Let’s say every month the artist repurposes the last pile of plastic with more glue. At the end of one year, the 10lbs would turn into 1100lbs. At the end of two years the original 10lbs would have turned into 1.3 million lbs of plastic waste. Surely that would frame a very powerful message about plastic waste and green washing misleading public policy.</p>

<p>I couldn’t figure out why US Bank business card applications using a sole proprietorship EIN kept disappearing into a black hole or being denied. Eventually after a few phone calls they complained about the email address.<p>The other was ferguson.com, so that I could order specialized furnace parts and larger diameter plumbing fittings than I could order from Home Depot. I don’t remember the details, but I think the Ferguson business application kept trying to autofill an address for me. It probably would have required a confirmation from the person who had been turned into the administrator of “fastmail” before I could have been added to their organization and been able to make purchases using their account.<p>It might not be a problem at larger suppliers like Grainger or Digikey, but it does suggest a vulnerability if you set up a corporate account at a small supplier using a fastmail address. Their backend could assume that anyone able to receive emails on “your” fastmail.com domain is at least authorized by your IT department to use email. If they assume your IT department has an email retention policy, then they might default to treating it like your problem if one of your employees makes an unauthorized purchase.</p>

<p>That's an interesting way to investigate how much public policy surrounding schools is actually focused on student education. I think you'd find that there would be significant fear around crime in an environment that already has a heightened risk of riots. For younger students the debate would shift to burden of additional childcare.</p>

<p>I’ve surprisingly found that I have started to have to use mydomain.com with Fastmail. Sometimes banks used for a business account, or accounts at b2b companies don’t treat fastmail.com as a large email provider, and otherwise try to associate me with other fastmail customers as though we are colleagues at Fastmail.</p>

<p>Samsung can increase its prices until they can’t sell all of their output, or they decrease their prices until there are shortages. Anywhere in between is just about allocating the surplus value to Samsung shareholders, executives and workforce or to consumers. If the chips are selling when Samsung is asking 40x profit then the chips are even more valuable than the price they’re charging.</p>

<p>Some people have claimed to hear an improvement with an external clock on a Wiim Ultra, but I do not think it is possible to re-clock the WiiM <i>Amp</i> Ultra with an outboard clock.<p>When I play from the computer, I'm not sure whether it is using the clock on my Mac, the clock on the optical interface, or the WiiM's clock. However, I do not notice any difference in fidelity when I use the Qobuz software player on my Mac or use Qobuz Connect to allow the player to directly stream from the source, so either it isn't a difference that I can hear, or the WiiM's internal clock is used for both sources.</p>

<p>My good enough amplifier and DAC combo claims up to 24bit/192kHz, I use a cheap optical interface from my computer that claims up to 32bit/192kHz, and the streaming service I use serves most albums at 24bit/44.1kHz.<p>It would have cost the same for the entire stack to be 16bit/44.1kHz at every step, but with excessive resolution I can control the volume anywhere. The bits right before the analog conversion at the end are essentially the same whether I turn down the volume in the software player, the operating system, or the DAC/amplifier.</p>

<p>So much of the content is extremely stale, and it even matters for languages that you would think are relatively unchanging.<p>It seems like they must have put almost no incentives in place for the instructors. Setting up a course must take even more effort than running a full semester course in their own school, but since no one is making new versions Coursera must not be paying them like it, or offering equity in the platform. I imagine that teaching students in person is also a lot more rewarding,<p>I haven’t taken any recent online courses, but EdX looked like it might still be good.</p>

<p>The model thinking course was interesting but it should have had a follow up that was much more than a freshman survey course treatment of each model.<p>Reading online it seems like most people got the impression that it was establishing that all models are essentially useless. Instead it was showing that each of these models were an extremely efficient way to understand some dynamic situations, but that it’s still absurd to focus on only one model when trying to understand the world.</p>
