You could only do things on the site during government business hours.
On the surface it was frustrating, but it also made the site feel 'alive' in a way that I hadn't felt since the days when even professional company sites had an about page that the 'webmaster' created with maybe a pic of the server, or his cat.
I have an idea in my head for a sort of "banking" (not a real bank and I wouldn't use that word) app and that it would be amusing to have it recognize bank holidays and typical bank hours.
With HolyClock you can prevent desecration of Shabbat by visitors of your website. A visitor who is located where Shabbat has begun, is redirected to a temporary closing page until Shabbat ends. """
It also gave some character to the site, making it clear that people were behind it. Of course they are, but the site too then felt a bit more personal.
- Forex buys and sells are disabled
- "Large" transfers are disabled (over some silly amount on the order of $2K)
- And my personal favorite, you can't see or pay your credit card bill (for Mastercard ONLY), and you get a "this function is not available right now, call the bank at $BANK_WORKING_HOURS_ONLY_NUMBER" message.
What was your home currency? Was it subject to any currency controls?
Here’s a http server: https://stackoverflow.com/questions/6329468/how-to-create-a-...
Not sure how much that would help the power draw of the graphics processor, but it would remain idle at the very least.
What I don't understand is why nobody does some kind of cheap battery backup for PC. Even cheapest UPS costs a lot and good UPS costs like a PC. While laptop battery is pretty cheap and provides a lot of power. All I need is few seconds to properly turn off the machine when power cuts.
Serves a website from the app on your phone, and their service acts as a proxy to send traffic there.
Very interesting!
I'm sure the average website of 10/20 years ago uses less resources, and by extension power than the current average website.
I suppose you could argue we do more with each unit of power, I would contend most of that has been wasted on non core frivolities that aren't worth the cost though.
Content providers however haven't really done much. Do you think app and web developers give much thought to battery life when they make their products? If they ever optimize it's for reasons such as responsiveness (which drives customers away if it's poor), and battery life is at best a sideeffect.
I also wonder if by optimizing for some combination of battery life, battery size, device size, Cost, QPS required, Sensors on-board we'll end up with something that has interesting monitoring capabilities in very remote regions.
edit - thinking about it, I am a mile off. Will be something like compiling a custom server and having no OS.
It's been tough deciding tradeoffs, and the way I've munged my images to be smaller still is not nearly as nice as whatever dithering technique they're using.
And traffic handling is another thing, what with my not-at-all-compliant socket server crashing as soon as it has to field more than 2000 connections at once, or if any of the connections tries to send more than 54Kb at once.
It's not nearly as power-effecient as a PIC, but it gave a tiny bit more flexibility. (Original prototype was MicroPython to prove it would work, which gave me a repl to live-tweak things, and now I'm using C).
This does highlight a possible new definition for 'progressive' websites. Websites that add features as more power is available.
-4x 100 Ah LiFePo4 batteries (BattleBorn brand)
-3000 watt charger/inverter unit (Victron MultiPlus)
-3x 360 watt solar panels (LG Neon R)
-Solar charge controller (Victon SmartSolar)
-System controller (Victron ColorControl GX)
-Battery monitor (Victron BMV)
-A lot of heavy wiring, ranging from 4 gauge to 4/0 gauge. Some segments are designed to handle 400 amps (12V DC, if my system was any larger I would have gone with a 24V or 48V design to keep wire sizes reasonable). Of course it has to be stranded and tinned wire for a marine environment, so think along the lines of $5/foot.
-An assortment of bus bars and circuit breakers. 100A breaker for each battery, 400A fuse for the main connection, $120 bus bars, etc.
It was a very interesting project for me personally and really a lot of fun, but solar can easily become a serious project as your scale beyond maybe 500 watt-hours per day. I haven't done a final cost summation of my project but I'm sure it was over $10,000.
But I understand that no votes should maybe not count as dup.
Neat, but this seems like it’s engineered to shut down, not engineered to stay up. I wonder if it’s on purpose.
> Less than 100% reliability is essential for the sustainability of an off-the-grid solar system, because above a certain threshold the fossil fuel energy used for producing and replacing the batteries is higher than the fossil fuel energy saved by the solar panels.
Looks like it's a messaging thing, mostly to show that such a website can be done. They discuss energy usage wrt environmental impact a lot on that page.
EDIT: that is to say, it's definitely engineered to shut down, rather than to stay up
All in all it's a rock that generates electricity when illuminated.
Removing the dither, and switching to heavily compressed JPEGs, would reduce the file size of the images by ~60% (I've just done it in Paint.NET), thus reducing network usage per request, which in turn would shave a bit off the power consumption.
