Found an app that uses the magnetometer sensor on the iPhone to give a readout in microtesla. I'm sitting at 350-400 in my room with the higher values coming from the computer and cables on the floor. The app says avoid anything more than 100 uT for more than four hours but I'm always in here. Nature undisturbed by human activity has a basal field strength of 49 uT. Is this unsafe?

DragonLord

That's oddly high, for what it's worth.

My tablet is giving me 40-50 uT.

guys I've some weird problem on windows10, after tweaking it, I had created other Admin accounts, now they are in c:/Users/ but they are not listed in control panel>accounts

Bob

@crl Search for "user profile" (start menu), looks like the profiles exist but not the accounts. Otherwise, lusrmgr.msc

crl

sorry it's in French, but you can see "admn" or "c" are not listed. So how do I delete them?

@Bob thank

In WIndows 7 that search would bring up a "Configure advanced user profile properties"

You can delete them from there.

@GuyF-W is that to the local gateway? Check packet loss statistics on the network card? Check jumbo frame settings. Check MTU and TCP offloading.

it's fluctuating. local network pings vary from 50% time-out to 300-800ms range. I'm not sure what jumbo frame settings are, but I'll look it up

Morn' all

I was wondering about monitoring my washing machine for when its cycle finishes, and realised that's getting dangerous to the "netBSD on my toaster" meme of old

...but if I were to; has anyone gone about such a thing? This washing machine is old++, and the likelihood of having any form of user-accessible network/serial output is somewhere between nil and jack squat

Bob

Most likely a mechanical timer with switches

You'd be monitoring main line voltage

bertieb

Sounds ~~dangerous~~ fun

DavidPostill

@bertieb Something with a microphone that detects when it has gone quiet ;)

Or a vibrator monitor ;)

bertieb

@DavidPostill That beats my "process image to detect when light goes out" :P

Bob

LDR for light, accelerometer for vibration

bertieb

11:03 AM

Ooh, a vibration monitor might be perfect, actually- there must be something along that line for the RPi

Complicating factor is that the dishwasher is right beside it, might introduce noise

Suppose careful placement + high-pass filter might suffice

DavidPostill

Just stick your clothes in the dishwasher. If a dishwasher will clean keyboards I'm sure it will clean clothes.

@Bob Normally I'd be inclined to agree, since this reading is basically ambient magnetic energy (which would come from things like WiFi, bluetooth, LTE, CPUs... check, check, check, check...) but it just seems odd that it's so high

If my numbers were similar to the numbers other people get near their computer, I wouldn't care

Oliver Salzburg

Hmm, my computer doesn't respond to Ctrl+Alt+Del, but I can still type

This is kinda weird

Well, and applications refuse to open, task manager only displays and empty list and other crazy shit

allquixotic

Ctrl+Alt+Del is handled by the kernel, IIRC... it's a very low level interrupt, even lower than explorer.exe

Oliver Salzburg

I know

Which is why it's confusing that I'm not getting a response

I'm guessing something isn't right

allquixotic

maybe a critical kernel thread or one of the core processes like lsass.exe or something is hung

but your browser doesn't use anything from that

Oliver Salzburg

Some applications refuse to start, while others work just fine

Well, maybe I just need a reboot. Had a couple too many of those for my taste lately

My gfx card broke on Saturday. Or so I assumed. Maybe something else is broken

Bob

@allquixotic It switches to the secure desktop, and that operation can take a long time.

Boris_yo

@Mokubai What was your experience?

Bob

Hmm

Could get a GS5 for $330

Mokubai

6:13 PM

@Boris_yo Solid and reliable, took a week or so to get properly used to but other than that it was just a pointing device. Part of me wants to go back to it.

I wouldn't use it for gaming, but plain desktop work it was great for.

Best thing was that it kept everyone off my computer. No one else could stand to use the thing for more than 60 seconds.

Bob

hm

Or LG G4 for $400. Or Xperia Z2 for $330.

@allquixotic Thoughts?

I'm sorely tempted (15% off at the moment, plus I have a $50 coupon that expires at the end of the month... was planning to put off the phone upgrade for a while longer but this might be the best I can get for at least a year, especially if the AUD keeps dropping...)

The G4 is almost perfect - I'd really prefer a physical home button but the SD support and removable battery are great. Z2 is also nice, but older-gen - still an upgrade over my S4 w/ Snapdragon 600.

DavidPostill

6:31 PM

@Boris_yo I got mine because of RSI in the back of my hand from using an ordinary rodent all day long. Like Mokubai it took a little getting used to (and an aching thumb for a few days of 8 hour use) but since then no RSI. If I didn't fix the RSI I would have been typing one handed for the last 10 years :/

(I don't actually know, I just wanted to use that phrase...)

DragonLord

tomshardware.com/news/…

sigh

This affects my system build plans.

allquixotic

@DragonLord three 4K displays is 75% as many pixels as an 8K display. A framebuffer of 24-bit color depth would consume at least 597 MB of VRAM, and that's ignoring the space you'd need for textures (which any 3d accelerated desktop, including all modern Windows and web browsers, will make heavy use of).

With compression you might be able to halve that, but in reality probably reduce the size by 25%.

DragonLord

I can understand why it's important from a business standpoint to aggressively pursue and enforce patents, but going too far is only going to hurt innovation for everyone.

allquixotic

If you had 4 GB of VRAM, you would need around 450 MB just for the framebuffer, and 3.5 GB of VRAM is not going to provide much space for texture memory when your textures are so big.

For reference, on a single-display 1080p monitor, when trying to view an 8K video (in any format, I've tried several), with or without hardware accel, I get about 10 FPS on a GTX 980.

DragonLord

8:58 PM

Every patent provides the potential for another revenue stream. When your business spends tens of millions or more each year on R&D, it's vital that you take advantage of the legal protection afforded to intellectual property to protect it—lest a competitor takes your investment and runs away with it.

allquixotic

I'd say the GTX 950 is grossly insufficient.

DragonLord

Then again, we must not forget that competitors must still have a fair chance to compete and come out with their own technologies and products.

allquixotic

@DragonLord Yeah, but not setting a reasonable value on what patents are worth (and capping how much revenue can be demanded from them) leads to a market that's exactly the 180 degree opposite of Pareto-optimality: you have different vendors selling incomplete, fundamentally flawed products, because nobody's willing to license their patents (they are, but they want a 50% cut of your revenue; ridiculous) and nobody has the complete picture.

Imagine if a company had a patent on internal combustion engines, and another company had a patent on car doors, and another company had a patent on tailpipes, etc. Nobody could make a car. Or at least not a good one. They'd have to carefully and cleverly work around the patents, leading to a sub-optimal product.

The best possible product would incorporate ALL of the fruits of the R&D labor into one integrated, unified product.

If the market denies that to happen, then the market has failed, and it should be improved or replaced as a system.

DragonLord

Well, there should be a legal requirement for a patent holder to provide an opportunity for others to license their patents under RAND terms prior to litigation if they cover a wide class of products.

Michael Frank

@DragonLord I probably wouldn't go with Cooler Master anyway...

allquixotic

9:04 PM

@DragonLord There isn't, though, and only certain specific standardized technologies are licensed that way.

Not enough to get to Pareto-optimal product development though.

DragonLord

For some reason, I feel like I should spend thousands on software licenses for products such as Visual Studio ($6k for Enterprise 2015 with MSDN subscription), even without a solid reason to do so, just because I feel I might need it.

Michael Frank

@allquixotic You mean like Microsoft putting out Windows Developer Enterprise Edition which includes all of their current + n development software in one package?

DragonLord

$200 for a full retail Windows 10 Pro license is one thing. $6000 for a software development suite and access to a large software library for development, large portions of which I likely would never use, is another.

Is it a good idea to do this (assuming the funds exist to do so)?

> assuming the funds exist to do so

...is a very strong assumption.

Michael Frank

@DragonLord I don't think it is.

A good idea, I mean. It's spending money for the sake of it.

Like buying anything that's <$1/$10/$whatever during the Steam Summer sale just because you have the money to buy it.

DragonLord

Note that the previous highest edition of Visual Studio (Ultimate 2013 with MSDN subscription) was $12,999. $5,999 already represents a significant reduction.

Michael Frank

9:17 PM

I don't think the cost has anything to do with it. It could be $600.

It would still be frivolous spending if you had no expectation to ever use the software.

DragonLord

Visual Studio Professional 2015 (without MSDN subscription) is $499.

The same issue underpins the planned Lucifer extreme desktop build. Will I ever take full advantage of an 8C/16T processor or two (or more) GTX TITAN X cards? (The price for this build currently stands at $5802.85.)

DragonLord

It's a significant advantage for servers where more cores are more efficient than faster cores for the nature of the applications they run, but the vast majority of consumers simply cannot benefit from more than 4C/8T in any meaningful way.

Michael Frank

Hmm.. I'd say that hardware is different as I would find something to push it to it's limits. But I can't really convince myself of that right now.

allquixotic

us tech enthusiasts can always find a way to use more hardware :D

DragonLord

Well, running Fishtest, a distributed computing framework for testing changes to the open-source Stockfish chess engine, is one use.

Running a game and doing other CPU-intensive tasks like transcoding videos (e.g. to compress them for uploading to YouTube) or processing lots of RAW pictures in batch at the same time is a more practical application.

@DragonLord In this case, the feature-set is largely already available in the Community Edition. For the most part, only larger teams/companies need to worry about a paid licence, IIRC.

And that's a good thing for both sides. Independent devs can get into it without such a large outlay, and MS can get devs into their platform/avoid scaring them away with excessive entry fees.
