You forgot the biggest reason: Winter. What works for benchmarking under nice Cali weather condition doesn't work for IRL. Current generation lithium ion estimates are ~30-50% halving of range in winter (it's especially bad if you don't have your own garage with charging and pre warming the battery can easily reduce the availability battery capacity by another few percent in exchange for better en route efficiency).

Which is why the new sodium-ion batteries are likely to be preferred in cold climates, because even if they cannot reach energy/mass ratios as good as the best lithium-ion batteries, they lose much less of their capacity and charging speed, down to -40 Celsius degrees (-40 Fahrenheit degrees).

While for now sodium-ion batteries have similar prices with lithium-ion batteries, due to being on the market for less than a year, their second advantage is that once their production becomes more mature they should be significantly cheaper than Li-ion batteries.


Oil is a mostly liquid (pun intended) market.

You don't really need AI to do this, it can be done just fine with traditional techniques, just labor intensive. Hell you can probably find a dude on fiverr to do it right now for a couple hundred, YMMV.

Well, you are mostly increasing liquidity and cutting out the middleman that is the wholesale purchasers and bidders. Price discovery is more accurate now for personal users as many tend to be physically closer to the location.

Does it work with the preprocessor?

I mean if you wanna leapfrog china just throw more money into switched mode inverters and rectifiers. You don't have to use transformers. As long as you have a black cheque, there are plenty of options.

What about businesses like roame.travel (YC company)? I think this toolkit just replaced services like that entirely

It uses Seats.aero under the hood, which is a Roame competitor, but I’d love to integrate it with others. Seats.aero is the only one with an API, though, which I believe is a mistake on Roame and others’ part.

The actual searching for actively available award flights is the part this relies on Seats.aero for


The short answer is that a lot of states now require KYC by service providers under the guise of adult content prohibition, "protecting the children", or mass surveillance. So the service providers like Facebook are trying to foist off the responsibility to the operating system. The pesky details of storing and managing PII becomes Somebody Else's Problem, and if the operating system implements an easily bypassed KYC e.g. a simple check box and then the kid get radicalized or get exposed to problematic content, the service provider can just shrug and point the finger at the OS. In other words it shifts the responsibility to the lowest level instead of the platform companies.

You can frame it nefariously, but honestly, it just makes way more sense to me. I want as little of my personal info as possible in the hands of random services, and that includes the stuff needed for KYC checks.

I wish NGINX marketed and documented their NGINX Unit server more. They go their lunch completely eaten by Caddy and the other kubernetes native Golang app servers and reverse proxies.

I had actually never heard of Nginx Unit, sadly looks like it's unmaintained now.

That is true at a certain scale, but there is also a reason why large organizations like Cloudflare ran nginx on their edge over any other product.

I just want one that tells me the maximum voltage and current supported by a USB C cable.


The Treedix will tell you that, as it is a feature of the eMarker chip (no chip means 60W).

Assuming the chip isn't fraudulently added. Like in the article, some manufacturers are shady & will sell cables with e-marker chips for capabilities the cable can't actually support.

Yes, but the only way to test for something like that would be to put the rated load and see if the cable smokes. Not something a family-friendly tester would do.

No need to check for smoke, just need to check the voltage drop between source port & sink port.

You need a >5A output power supply, two voltmeter channels (for source & sink), one ammeter channel (to sense applied load), an electronic DC load (actively cooled FET that uses the ammeter to set a constant current), a microcontroller, screen, some buttons, and software to run the whole thing. Or the manual version: Lab power supply, some USB connector breakout boards, a DC load, optionally a multimeter, a pencil, and some graph paper. Set the power supply current limit over 5A, voltage to 5V, set the DC load to 500mA, and measure the voltage at the power supply & DC load every 100mA as you increase it up to 5A load (or 3A if the cable isn't marked for 5A capability). If the sink drops more than 0.6V below the source, the cable is not compliant.


Right, but you can't expect a pocket sized tester like the Treedix to implement that, even if it is the USB standard test for compliance. The Treedix does measure resistance on the cable, however, so if a cable exceeds 250mΩ it would also flunk your more accurate test.

there are several: one that is moderately priced and which I consider myself to buy is the JOY-IT UM120

Thanks, why do you prefer that particular model?

I wanted to have a model which tells me the modes which are supported and which is actually selected for a reasonable price and which I can order at a reasonable trader. this model seems to do the trick
