icehawk··on Yes, you can play Duck Hunt without a television (but I can't)
Since that looks like your normal camera flash circuit with xenon tube (the cap values are on point for one) I'd agree its likely the cap, unless there is anything visibly wrong with the flash tube.
icehawk··on The largest solar farm just came online in China
As linked in the GP, solar production as a percentage of total generation capacity China is 4.8%, just like the US.

Is that something that needs to be considered separately, since the operation factor is given in % of hours per year?
icehawk··on Things the guys who stole my phone have texted me to try to get me to unlock it
Deterrence against thieves is a pretty big benefit.

Meanwhile there's massive amount of low-quality parts i have to wade through when wanting to order a replacement battery.

icehawk··on ICQ will stop working from June 26
That's very rose colored. It was only universal if you installed a third-party client and set up each one separately, or installed a half dozen applications.
icehawk··on Big Tech to EU: "Drop Dead"
As a consumer, I am particularly unsympathetic to what what Apple is doing to developers.

The developers do the same to me when they have the opportunity.

icehawk··on Wind farms can offset their emissions within two years, new study shows
I'll totally admit wind farms make me feel fuzzy at night-- mostly because that's when they produce >50% of total power on the grid where I live.

> roads don’t make noise

You're proving GP's point. Roads on their own don't make noise, but if I go outside I can hear the road noise from cars going down a IH-35 which is a mile away. (It isn't even the only road I can hear noise from)

icehawk··on The iPad Pro Manifesto (2024 Edition)
Having used Wacoms for years before trying things like the Surface Pro and then settling on iPad? The iPad 100% beats every other tablet I've used.

How well the iPad / Apple Pencil work for drawing very much adds color to posts here berating the iPads for being a content consumption device.

icehawk··on Whole-body magnetic resonance imaging at 0.05 Tesla
When a cell phone camera auto-focuses, it's still literally recording what light strikes the cmos chip.

Do you think its recording some other light?

icehawk··on Coronal mass ejection impact imminent, two more earth-directed CMEs
PJIM is at 'Action' now:

' A Geomagnetic Disturbance Action has been issued as of 22:15 on 05.10.2024 to protect the power system from damage or disruptions due to increased geomagnetic activity.'

icehawk··on Computer models suggest modern plate tectonics due to blobs left by collision
The sun will become more luminous to a point it will stop plate tectonics by evaporating the oceans far sooner (about a billion years from now) than it will take the earth's core to cool.
icehawk··on Deaf girl is cured in world first gene therapy trial
Why does there have to be an end goal? Why cant things just do the thing they do?
icehawk··on Monitoring energy usage with smart plugs, Prometheus and Grafana
It might be, but for all of the examples in the blog post, HA does this out of the box.
icehawk··on 'Catastrophic grid failure' a possibility for Texas solar/wind/battery storage
> For example, a battery that primarily functions in the frequency regulation market (modulation of supply and demand every few seconds) doesn't need a lot of storage capacity, but needs high power output.

For ERCOT this is fixed as a hard requirement so there's no point in specifying the time-- it's all going to be the same. For example:

> Fast Frequency Response (FFR) – subset of RRS

> – Must be capable of sustaining its required response for at least 15 minutes (if necessary)

icehawk··on 'Catastrophic grid failure' a possibility for Texas solar/wind/battery storage
> It's a whole different paradigm than your UPS under your desk is: With your UPS, your system(s) receive a signal that things are running on local battery, and you've elected to configure things to use that signal to order an automated shutdown.

The setup you described there wasn't the situation I was describing at all.

I was describing a situation where there is utility power, a UPS, and a standby generator. When the utility power goes out, the generator has to start, stabilize, and only then can the load be transferred off the battery.

The requirement is that the UPS meet this current power demand for longer than the generator start up and transfer time (the "holdover time" I was speaking about in the previous post.)

For things like frequency response the holdover time is a fixed requirement. ERCOT requires all energy storage resources be able to maintain output for 15 minutes.

icehawk··on 'Catastrophic grid failure' a possibility for Texas solar/wind/battery storage
Its fine as long as the amount of time it can provide rated output is longer than it time it takes to bring replacement generation capacity on line.

I don't care how long my UPS will actually last as long the holdover time is long enough to cover the time it takes to deal with all of the foreseeable problems in starting up the backup generator.

icehawk··on Google made me ruin a perfectly good website (2023)
Yeah and I did that 10 years ago when the math worked out differently. 'Recently' is doing some work in that comment.
icehawk··on So you want to scrape like the big boys (2021)
I'm glad you agree with my point that Walgreens owns their merchandise not because they stop shoplifters and restrict access, its because they purchased it and have title over it, and since GP has done no such thing they don't actually own it.
icehawk··on Google made me ruin a perfectly good website (2023)
Google has been sending me emails about how things are preventing them from indexing my websites,and recently I've stopped caring.

My website and it's content is what it is, and its not my job to make Google more valuable. They're a multi billion dollar company, if it's really a problem, they can figure it out.

icehawk··on The walls of Apple's garden are tumbling down
Ok so what is your point? That's the carrier.
icehawk··on So you want to scrape like the big boys (2021)
Given that you haven't fixed your problem with scrapers (given the complaints you're making right in this thread.) It's obvious you're not in a position to restrict the data-- otherwise you'd not be complaining about scrapers, and thus you don't own it.
icehawk··on Court upholds New York law that says ISPs must offer $15 broadband
And then Circuit 1 and Circuit 2 are taken down at the same time because even though they have diverse paths they're part of the same underlying DWDM system which has just encountered a fault.

Ensuring there isn't a single point of failure is not just as simple as 'putting it in the contract.' Carriers can and have groomed their primary and backup circuit on to the same L1 path without realizing it.

icehawk··on Nintendo forces Garry's Mod to delete 20 years of content
These are game assets so its copyright law. Nintendo even used the DMCA to issue takedowns.

Trademark defense has nothing to do with this at the moment.

icehawk··on Show HN: My $1k self-install, off-grid solar backup build for renters
Not reading the numbers on the label is an orthogonal issue.

My point was gauge and maximum rated amperage are on the label.

icehawk··on AI made these movies sharper – critics say it ruined them
For anything that's not just "grab a camera and shoot the movie" the format that it is shot in is absolutely taken into account. I don't think you can separate the story from how the image is captured.
icehawk··on Show HN: My $1k self-install, off-grid solar backup build for renters
They're very well marked at Home Depot.

The store brand, which is general most prominent, gauge is color coded: 6AWG - Gray / 12AWG - Yellow / 14AWG - Pink / 16AWG - Orange. There's one exception to this where 14 AWG cable is using orange labeling normally used on 16AWG wire but that's the opposite of a safety issue.

And they have generally have the rated amperage for the length of the cable.

One doesn't have a tomorrow without a yesterday.

icehawk··on Going in circles without a real-time clock
and you certaintly get what you pay for, DS3231s fry almost as easily as MAX3232s,

(And you can do the same thing were you write the time to the RTC before you have the correct time)

why isn't it? What prevents that?
