I see 400 Amp service more often than not, in my travails amongst "big, fancy, new" houses.
I agree that it should be extremely rare, but it's amazingly common in those new neighborhoods.
When I owned a big, ancient house, it was full of electronics and space heaters (because bad heat and cold winters) and lived fine on 2x 120A (60x2) entrances: There were no problems. I don't know why anyone would need 400A residentially, especially since those folks tend to be more frugal with electricity than me, but whatever.
Which you said the device wouldn't have had, but there it is.
All outward appearances would suggest that it is a custom chip for Samsung
It's not like they're a small customer. This isn't unusual.
Personally, I expect that the MAX77838 is similar to the MAX77829
Because you Googled MAX77838 and found MAX77829 in the top few hits, just like anyone else who has used teh Intarwebs can do.
Unfortunately for Samsung, the charging circuit has to be relatively tuned to the specific battery being used. Generically designed Lion chargers have a habit of failing.
Gosh, I wonder why they used a custom part. Any guesses?
Oh.
So much so that Tenma actually ships many of their battery chargers with a fireproof pouch to put the battery in while charging it...
Are you seriously using Shenzen China Export products resold by MCM Electronics as a basis for comparison? Tenma has always been garbage. We might as well be discussing electronics from Harbor Freight.
This just goes to show how stupid Samsung is for designing it this way.
You say that, but you don't use your words to demonstrate it. Does the term "red herring" ring a bell?
The irony is that the PSOC processors cost cost about $5 each and they are full featured processors while the Maxim ICs Cost more than that and are just a PMIC.
You don't know what is in the MAX77838. You've said as much.
Samsung is staffed by incompetent engineers.
They fucked this one up, for sure. But are you at all aware of the millions of wildly popular Samsung devices out there which don't tend to autoignite?
Mistakes happen, even with competent engineers. Sometimes, big ones. I recall a certain incident wherein BMW tried to sell diesel cars in the US, but our (relatively) crappy fuel ate the cylinders and ruined compression. They put a new engine in each car they sold here, with updates to make it not an issue.
Also, the Ford Pinto.
Firestone Rollover Tires. Unintended Toyota acceleration. Concrete falling from the roof of the Big Dig tunnels. Et cetera.
Early 90s O'Reilly books were largely reprints of Linux HOWTOs, and were awesome.
Later 90s O'Reilly books were just as good, without the (freebie) HOWTO background, and were also awesome.
i think you've got it backward, though: In OReilly's proper hay-day, they were printing texts that were easily found online.
(I'd tell you to get off of my lawn, but given your UID, I must respectfully thank you for letting hang out for as long as I have, instead. There aren't many of you left in these parts.)
Sure. I use one of these, with this firmware, making it a cute little self-contained Linux box with both a HTML GUI and a command-line interface that is as complete as you want to make it. (I've got a build environment on mine, just because I can.)
802.11ac, dual-core 800MHz ARM, 256MB of RAM and 128MB of flash (all of which are complete overkill for this application), along with multiple USB ports for plugging in random goodies.
In this lesser Slashdot that we have these days (wherein I don't even see anyone saying "just use an old box for pfsense and be done"), I'll second Asus.
The stock firmware is allegedly built upon OpenWRT, and for those that like Tomato-USB/Shibby, they're generally all well-supported.
I have had many small networks that would have fallen over (and indeed, were actively falling-over), which were absolutely saved by proper QoS rules in Shibby's builds of Tomato-USB.
For the home-gamer: Multiple massive torrents, voip, and Netflix, Youtube, general web browsing and email, and low-latency gaming on the same absolutely-saturated cheap last-mile pipe? Easily handled, and all work fine.
For your electric oven to use more than that in 20 minutes, it would have to draw more than about 87,600W for each of those 20 minutes, or about 380A @ 230V.
Either you are lying, don't understand the math, or we'll be requiring pics showing this oven.
I can use my Galaxy S7 with regular gloves. Home button, other physical buttons, capacitive buttons, touchscreen stuff -- whatever. The sensitivity is software-adjustable.
It works fine. And it has a better IP rating than the new iPhone.
It also has a headphone jack, and what seems like a very sensitive barometer.
The point is to decrease the signal-to-noise ratio so that finding good, reliable data as to whom is doing what is harder, which is pretty much all that encryption has gotten us so far anyway: It makes it harder.
Anyone who believes that their data is secure in transit on a public network is a lunatic to whom I'd like to sell a bridge. I would also like to take this time to draw into question the sanity of anyone who chooses to think that there's no good reason to make the job of spoofing to be as difficult and drawn-out as possible.

Oh. It's the local "recycler" who has to deal with the firebombs.
No thanks.
How do you know that your WRX isn't running QNX?
If these features are important to you, then why didn't you test this stuff out before you bought the thing?
Which you said the device wouldn't have had, but there it is.

It happens. Engineers are human, just like you.
I didn't see a fight.
Suppose we use your theory, and take a Samsung firebomb back to the retailer.
They remove the battery.
What happens then? Where does it go? How does it get there?

How many battery packs have YOU designed, Internet-guy?
Over here in facts-based land, the Note 7 has a MAX77838 keeping track of power.
Yep.
AirBRB isn't a tech company, Lyft and Uber aren't tech companies, and NASA/NOAA/NWS aren't companies at all.
The only tech company listed is Verizon, ish.

Why do that, when for $50-$100 you can get an ARM box that just does everything -- including AP duties -- while also consuming insignificant power?
It even comes with a reasonably-good Gigabit switch that can also tackle VLAN duties.
Thanks for the flame, though. It almost felt like old times.

Surely you can shove OpenWRT, Shibby's build of version of Tomato-USB, or (*shudder*) DD-WRT on the thing, yes?
That would be Photonic Induction. His YouTube channel is better than his washing machine video.
Use Waze if you want to get someplace on a route that is both statistically faster, while also going around unusual traffic conditions where possible.
(It's not always possible.)
Watts *is* power.
And he said his oven uses more power in 20 minutes, than a whole pile of other gear does in a month.
I thought he was pretty clear about what he meant, despite being wrong in his assumptions.
Huh?
A month of 40W is about 29.2kWh.
For your electric oven to use more than that in 20 minutes, it would have to draw more than about 87,600W for each of those 20 minutes, or about 380A @ 230V.

That's ok, he's also got plenty of antacid.
Yep.
Same with my previous S5, though the responsiveness with gloves did leave a bit to be desired it was still able to be used.
I'm totally not understanding the current fanboy-isms surrounding the new iPhone's issues.
Who said anything about height above ground?

What does local topography have to do with measuring height above sea level using GPS?
