tobobo commented on Tesla created secret team to suppress thousands of driving range complaints reuters.com/investigates/... · Posted by u/mfiguiere

As a Tesla owner, I think the source of the confusion is the EPA range displayed in the HUD on the Tesla. We toggled ours to show the battery percentage, which is much more useful to us.

We've never owned a gas vehicle that met it's EPA range and the Tesla is no different. No one takes EPA MPG * GALLONS of gas and expects it to be a real life estimate of range.

Wind resistance increases EXPONENTIALLY with speed. Drive a little over the speeds the EPA used to determine range, and the observed range will drop significantly as a percentage when compared to the EPA range for any vehicle.

If you do have a Tesla, you'll quickly find out that the trip computer is very accurate. The worst I've seen is a cold January day in Wisconsin (-10F) while on a road trip with a head wind. In that scenario, the trip computer was off by 7% mostly due to the head wind. In the summer, it is spot on usually within 1 - 2%.

My 2021 Honda CR-V doesn’t get close to EPA MPG but the range calculator is still accurate to within maybe 15%. I’ve tested it a few times driving from Oakland to LA which is right around the full range of the car and it gets pretty close- even with a whole mountain range to drive over north of LA. It doesn’t appear to use EPA MPG for its estimates and it makes for a better experience.

Definitions we use when rating savings opportunities are below.

Right now users can’t edit the difficulty but that’s helpful feedback if you think it’s something you’d use!

Would you want the ability to change difficulty to one of our fixed difficulty categories or the ability to add a custom difficulty unique to your org (e.g. custom difficulty based on internal approvals/processes at your company)?

Easy: zero downtime, zero performance risk

Medium: zero downtime, potential performance tradeoffs

Hard: downtime required, potential performance tradeoffs

This seems like a fair way to split it up and would apply to a broad range of scenarios. I actually lean towards the tool being more opinionated about classifications like these- I’ve seen many tools that bog themselves down because people focus on making granular adjustments to the tool itself rather than using it to execute. A special purpose tool like this should be able to nudge me towards best practices without giving me too many opportunities for distraction!

How do you define difficulty? I’ve seen companies with vastly different opinions on difficulty based on how they’re set up. Can I edit the difficulty based on my own company’s needs?

Skateboarding. The mixture of creativity and physical exercise is extremely rewarding and it’s humbling to fall on concrete from time to time.

His personality really comes out in this statement:

and will drop by the office occasionally, saying he plans to be in the Bay Area "on a regular basis" as travel restrictions ease.

Anyone who thinks they can jump this many time zones 'regularly' and be just as productive, either doesn't travel often, is deluding themselves, or is trying to paint a false picture of themselves to the public.

New Zealand is a long flight but IIRC it’s about a 21 hour time change to California (give or take DST) which only feels like about 3 hours. (Not defending the subject of the article, just an interesting time quirk).

tobobo commented on Real-world CSS vs. CSS-in-JS performance comparison pustelto.com/blog/css-vs-... · Posted by u/______-

I've never really been comfortable with the idea, as I was raised on the idea that separation of concerns is good thing.

I think one of the main appealing aspects is the idea of never having a styling conflict with other components ever.

Less macro-level management and organisation required.

Edit: sorry, just realised you're talking about a specific implementation.

I don't see CSS-in-JS as a rejection of separation of concerns. In fact, one of the big advantages of CSS-in-JS is that it lets you decide how best to separate your concerns.

Using hand-tuned CSS will undoubtedly be the most performant option, but it leaves you with very difficult problems at the boundary of your styling and content/structure concerns. If you have even a sliver of dynamic content in your website, it will quickly become near-impossible to verify that your content and styles work together as expected, or even to verify that your class names match between your CSS and HTML.

On the other hand, if you use CSS-in-JS, what you lose in performance you gain in compatibility guarantees between your concerns, regardless of how you prefer to separate. Are you putting your styles in the same files as your layout components to fully separate one feature from another? Great, you can unit test those components and be reassured that the elements are styled as expected. Are you isolating your styles to only a certain subset of components that deal directly with styling concerns? Also great—if you're using TypeScript, you can guarantee correct use of those styles at build time.

For a large enough team, those guarantees really pay off. If you have lots of customers using 2G/3G networks and want to hand-roll your CSS, I commend you! For most products, I think there's a better way to make that tradeoff and your users won't mind a slightly slower experience that has fewer bugs.

I'm in Australia, and here iPhones have about 50% of the smartphone market, with the other half being Android of course.

I obviously know many iPhone users, including my wife and many close friends. I know of no one who uses iMessage. Here everyone uses Facebook Messenger and WhatsApp (and to a lesser extent Telegram and Signal).

Is this iMessage fascinating a US thing? Why?

tobobo · 5 years ago

In the US almost everyone uses SMS. iMessage uses the same app as SMS, changing the message type based on whether the recipient can accept iMessages. So, most iPhone-to-iPhone communication ends up being SMS because we don’t have to change what we’re used to.

The motion reminds me of the “crab scratch,” [1] a DJing technique that uses finger tapping to move the cross fader rapidly in a similar way. I wonder if someone brought the technique over from DJing or if it’s a kind of convergent evolution.

tobobo · 5 years ago

Interesting. I’m currently working on an “IoT” device and this seems like it could theoretically work. One concern I have is that there’s an initial step where the device creates an access point so that you can enter wifi credentials that it will use to connect to your home network. In this case, the device connecting to the local server will not have internet access, and would not be able to resolve the plex.direct domain. Maybe I can rely on the browser dns cache, but that seems pretty sketchy...
