Root Access

ahh

cool

So the basic behaviour I want it plausible

2:58 AM

@JourneymanGeek That's honestly a pretty big surprise, at least as far as tablets go.

@Bob and netbooks.

@JourneymanGeek Actually, no. Looks like PCWorld was just wrong...

Or at least if we take AnandTech as more trustworthy :P

> Also not discussed in greater detail is Intel's future plans for their overall Atom lineup. With Apollo Lake announced just earlier this month, it's clear that Intel's Atom efforts have not been cancelled entirely. We will still see the new 14nm Goldmont cores appear in low-cost PCs under Apollo Lake, most likely in several 11-to-13 inch high volume devices. However for the moment there is not an Atom core on Intel's roadmap beyond Goldmont.

> What's less clear at the moment is whether this will also impact the low-cost/non-premium tablet market - as embodied by products such as the Surface 3 - as Intel is not discussing the status of the Willow Trail platform at this time. Previous comments made to Patrick Moorhead indicate that tablets are impacted, but for the moment Intel is staying mum on anything that isn't smartphones.

So, yea, a certain amount of assumption on PCWorld's part.

And it kinda makes sense... Atom is rare on smartphones, pretty much just Asus and Lenovo. But it's very very popular on tablets.

I was kinda expecting them to licence the cores.

Yeah.

Anyone tried this out ?

Nup. Not running a preview at the moment.

Reminds me that I need to install VMware again.

3:47 AM

Hm, I;ll get it when it comes out to everyone I guess

for some weird reason vbox won't let me create 64 bit VMs

I need to check if VT-X is enabled

Windows 10 new bash users. Welcome! The first few commands you should master: ls cd rm -rf /mnt/c #Build2016

Tweeted by seesharp on March 30, 2016 at 4:16 PM

lol

That's a very Richard thing to do.

4:28 AM

@JourneymanGeek Also possible that something else is using VT-x. Like Hyper-V.

Once you install Hyper-V it's always on.

Hyper-V doesn't support nested virtualisation yet.

Pretty sure I removed hyper V

@JourneymanGeek Well, you want to be more sure :P

When you install Hyper-V the "host" instance is actually virtualised too.

lol.

@Bob there was a vbox update that fixed it

hm. No

it did not

potentially delete everything on your c drive

cd change directory

rm -rf /mnt/c - delete everything in /mnt/c recursively . In the case of bash/ubuntu for windows, that is where your c: is mounted

!!ihavenoideawhattonamethistaylorswiftcommand

6:11 AM

heh. I fixed the 'hum' in my audio gear

I moved it under the other monitor, since that has a non metalic base.

Dammit, just bricked an otherwise usable 18650 Li-ion cell after 21 months of service by using it to drive a high-power inductive load.

It's a protected cell; must have busted the protection circuit.

I've got spares on hand so no biggie.

18650s are cheap anyway.

Which makes no sense since both devices that were having a seeming ground loop arn't sitting on metal bases, and one has a plastic case.

6:27 AM

(namely, a motor from a vacuum cleaner which was dismantled due to a failed NiCd battery.)

Didn't expect the motor to pull such an absurd amount of current even with a 4V input.

At least the cell protection failed open, rather than short.

The latter is potentially dangerous as the cell effectively becomes unprotected.

I still have one more spare cell in the fridge.

Alright, back to work.

Any comments on this, just let me know.

7:25 AM

@bwDraco You realise motors pull their max current at stall?

In fact, a low voltage might've made it worse.

It's a dumb brushed motor.

A low voltage might not even get it out of stall.

No motor controller, no nothing.

The motor did spin.

@bwDraco It's basic motor physics.

Doesn't have anything to do with a controller.

Current draw at typical load is generally far lower than current draw at stall.

Current draw at no load (full speed) should be almost nothing. Assuming, of course, that it has a max speed - otherwise it'll fall apart first.

I know, but the stall current was far, far higher than I had anticipated.

7:27 AM

There's a pretty good write-up here: electronics.stackexchange.com/questions/229218/…

The back-EMF current must have overwhelmed the battery's protection circuit.

@bwDraco Nope.

The lack of back-EMF would've caused it to draw too much current.

Unless you're applying external torque to the motor, the back-EMF should never exceed forward current.

Then why would this burn out the protection circuit when a dead short wouldn't?

Are motors pulsed loads?

What makes inductive loads so pathological?

@bwDraco So you tested a dead short?

Could be any number of reasons, really.

I don't have the full details of what you did.

If I try to short the cell, it'd just shut down immediately with no ill effects, and nary a spark is seen.

7:30 AM

It's even possible that the motor drew so much power that it under-volted the cell.

The cell was fully charged.

@bwDraco And what do you short it with?

Just a wire.

What kind of wire?

Could be that the motor actually has a lower resistance.

Just a regular copper wire.

7:32 AM

Thickness is significant.

Or you could just measure resistance of each with a multimeter.

It's a very short wire. The resistance should be trivial.

It's also possible that the motor was at the boundary where the protection circuit does not cut off while a dead short does.

For some reason, motors create bigger sparks when connected than short-circuits. Why?

It's like the voltage is higher than the output of the cells alone...

@bwDraco The diameter of the wire is still significant.

I've seen plenty of short copper wires that have a very high voltage drop when drawing an amp or two.

Do inductive loads cause very high peak voltages, above the voltage of the input?

7:36 AM

For reference, a 20 cm long 28 AWG wire will draw just under 100 A at 4 V.

@bwDraco What's the rating of the battery you're replacing?

The motor was originally designed to run on a 14.4V NiCd battery pack.

How long did the motor run for, what kind of load was on it, did it spin smoothly, etc..

The motor ran at a slow but constant speed with four AA NiMH cells. There was no significant load on the motor except for the fan blades.

And with the Li-ion cell?

Started up for a tiny moment before the protection circuit shut the cell down.

After a few tries, the cell just failed altogether and would not charge normally.

It did have some power. The cell read 4.0V open-circuit but the protection circuit had failed.

7:44 AM

You didn't happen to have an ammeter hooked up to it?

No.

@bwDraco What makes you think the cell failed (or protection circuit), then?

The cell would not charge or supply power normally.

And what cell + circuit was this?

It'd just drop the load if I tried to pull a non-trivial amount of power from it.

It's a protected 18650 cell intended for use in flashlights.

7:45 AM

Because there's a decent chance it's just a shoddy protection circuit that cuts out fine with a very high current (short) but takes time to do so with a motor.

@bwDraco Lots of quality variation there. Going to have to be more specific.

Nitecore NL189. It's not a no-name.

It's seen a considerable amount of use before.

Like I said, it's been in use for 21 months with little trouble until now.

Eh. NCR18650B wrapped by Nitecore?

Yup.

Probably a bad protection circuit.

These protection circuits are not designed to cope with high-power inductive loads.

@bwDraco You could pull it apart and take a look.

@bwDraco Seems more likely that it's just a polyfuse that you've killed by repeatedly tripping.

Polyfuse? I guess I'll give it a day or so and try again.

The underlying cell seems to be fine.

7:50 AM

@bwDraco They have a limited lifetime.

Repeated trips, especially in a short period, could have permanently damaged it.

7 mins ago, by bwDraco

After a few tries, the cell just failed altogether and would not charge normally.

I bet if you full shorted it multiple times that could've happened too.

The other thing is it trips faster if you draw a really high current.

So the slight overcurrent of a motor might've actually been worse for the fuse than the dead short.

It drops to about 1.0V and stays there until I put it back in a charger.

The cell goes back to a normal voltage (4.0V) but doesn't seem to be accepting current; might be a failed protection circuit.

The cell impedance is extremely high.

Alright, it's getting late.

I'm not going to trust it.

Heh.

@bwDraco Should've thought of that before trying it :P

(Drawing large currents from a Li-ion battery... yeesh)

In a way, you're lucky the protection circuit worked.

1 hour ago, by bwDraco

At least the cell protection failed open, rather than short.

1 hour ago, by bwDraco

The latter is potentially dangerous as the cell effectively becomes unprotected.

@bwDraco Max continuous discharge is a bit under 5 A.

There was probably a 5-10A or so peak.

It's this "just over the protection limit" that probably caused the failure.

So the slight overcurrent of a motor might've actually been worse for the fuse than the dead short.

kinda lame solution,use ufw ? :P

(I run nginx, I have no idea)

yeah sir..

lighttpd can be used to makew apache talk with hosts.deny file right?

sorry

if it was apache, i could find an answer to deny selected hosts.

apache 2 looks kinda hard

somebody able to make this out..?

Yeah, still whoa

Got linked in from somewhere

No idea how I opened it

But that's a whoa story :D

It is

quite honestly a "hey. not cool" would have been a good start

i can't help but feel in these situations sometimes it's a 'oh, thats a good reason for us to get rid of xxx...'

It's funny how she's all like 'stand up for women!'

then instead of saynig something to the guy

she snaps a photo, reports him, gets him fired...

@djsmiley2k I think she sort of didn't expect it to blow up that much.

10:07 AM

if i took a photo of a woman, i'd get arrested for stalking etc

hmmmm

Lots of people want to "Start a conversation" without actually wanting to listen.

but she's a 'social media something something'

@djsmiley2k so basically a PR person

and yet she didn't see this coming?

XD

holy crap i got good at my job accidently!

@djsmiley2k Apparently not

10:09 AM

with the numerous times this kinda thing has happened

@JourneymanGeek pardon..?

@kiranbbnl essentially this specific chatroom is mostly 'general' chat

so we get sidetracked a lot

@djsmiley2k I'm not saying she was totally wrong

yeah.... 'general' right...?

But tweeting about everything...

@kiranbbnl see humourous list of acceptable topics off to the right ;p

This place works better as a sounding board than a "hey I need an answer now before all hell breaks loose" place.

if someone is offended, I'd hope they have the guts to say so to me

10:11 AM

@djsmiley2k precisely!

if you're gonna slink off and say it else where, it shouldn't have any repercusion on me unless it's highly offensive on a large scale.

(such as ken livingston and hitler comments...)

She thought 'oh cool some free PR'

"Hey, I couldn't help but noticing you guys joking about dongles. I feel a uncomfortable about this"

sure

the thing is, even most guys are sensible/sensative to this kinda thing now

@djsmiley2k and seemingly thinking it helps women in tech.
