Chat of Things

Henry WH Hack v2.0

10:35

Hello My Good People! :)

How are things?

Aurora0001

Hi @HenryWHHackv2.0!

I noticed you've registered for the chat event, which is great

Henry WH Hack v2.0

Yeah

I am canceling my moderator noimation and waiting until the site is fully launched to become a mod. By then I should have enough knowledge to know what I am doing.

Aurora0001

Fair enough, you can always just get most of the moderation privileges through rep

Still, we've got to actually get in to public beta first

Henry WH Hack v2.0

My SE gold is to get a Marshal Badge on every SE site! :)

Aurora0001

It's not all that hard on big sites like SO

Much harder on sites like IoT

Henry WH Hack v2.0

10:46

I mean every SE site

all 161+ of them.

Aurora0001

Yeah, I know, just saying it's easier to get it on some than others

Henry WH Hack v2.0

How long have you been on SE?

Aurora0001

About 6 months

Henry WH Hack v2.0

Me 1 year 1 month

Aurora0001

I only have Marshal on SO

And most of those flags were 'should be closed' flags

Which aren't really that useful

Henry WH Hack v2.0

10:48

I am about to get one on Ask Ubuntu.

I flag spam most of the time.

Charcoal HQ

Where smoke is detected, diamonds are made, and we break thing...

20

218

Where every SE spam and abusive is reported!^

Aurora0001

I hardly ever see much spam

Probably thanks to people like you

Ghanima

Marshal is a tough one on small sites

Aurora0001

~~tough~~ impossible

I doubt we'll get 500 flags in 3 months

Ghanima

e.g. it hasn't even been awarded on RPi.SE though the site is up for four years

Henry WH Hack v2.0

It's my job to flag spam and abusive post! :)

Aurora0001

10:50

@HenryWHHackv2.0 you can always artificially create some ;)

Ghanima

I have more than 300 flags there and I think that's much for the site (and I stopped flagging when becoming a mod - that's the deal)

Aurora0001

(obviously joking, don't actually do it)

Ghanima

@Aurora0001 don't you dare

Aurora0001

Well, someone has to keep the mods busy

:P

Henry WH Hack v2.0

Have anyone here been suspended?

Aurora0001

10:53

I haven't

Henry WH Hack v2.0

No body?

Ghanima

I highly doubt it given that there are no mods

Aurora0001

I think @HenryWHHackv2.0 just means in general

Has anyone been suspended from any SE site

Right?

Ghanima

oh, that

Henry WH Hack v2.0

Ok I have been suspended on AU.

Aurora0001

10:53

What did you do?

Henry WH Hack v2.0

Well I have a private message

from an AU mod.

@Ghanima May I?

Ghanima

may what?

Henry WH Hack v2.0

show the private message.

Aurora0001

I think they probably prefer that you don't, but I doubt you're actually forbidden

Ghanima

idk, I am not aware of any rules. If you're the addressee you should in theory be able to share it at your own discretion... whether that is preferable to SE or not is not for me to decide

Henry WH Hack v2.0

10:56

Let's keep private in the private message OK! :)

Aurora0001

You can always just say what it was about without sharing it, of course

As long as it's nothing private

Ghanima

obviously mods are not supposed to disclose such messages concerning third parties

Henry WH Hack v2.0

Ah^

Aurora0001

@Ghanima indeed, but there's no arrangement the other way

Recipients never agree to keep it private

Because, after all, the privacy is mostly to stop users getting upset

Since you wouldn't like it if SE put you on a 'naughty list' publicly

Henry WH Hack v2.0

That's it!^

Poor me! :'(

Ghanima

11:09

well, I think that mod messages are not intended to act as a badge of honor ;)

I think they had a point to make and I am sure that you got it

Aurora0001

@Ghanima they're like battle scars - @HenryWHHackv2.0 battled against the mod, and came out alive

;)

Ghanima

that's part of moderation, Aurora, leave a survivor now and then to tell the tale

Aurora0001

So mods are more like cats then - play with their prey, let it go free, then catch it again shortly after

Questions seem to be going down again (boo!)

We're under 3 per day now

Which is concerning again

Ghanima

so you're up again

Aurora0001

I think if we drop too low, people will get bored with the site and leave

Also, seems like people have slowly got bored with my questions :P

Also, anyone who wants something easy to do, why not write a couple of tag wiki excerpts

You can write a good one in under a minute

iot.stackexchange.com/tags?tab=new

The proper tag wikis probably take a little longer

Aurora0001

11:52

@Ghanima, edits should be approved

Anyone want to do the biometrics tag wiki?

Henry WH Hack v2.0

12:05

I am a member of so many SE sites I can't keep track of them.

Aurora0001

Hi @anonymous2

anonymous2

@Aurora0001 Hi!

Keeping busy through the Holidays?

Aurora0001

A little, yeah, how about you?

anonymous2

Very much so.

Especially what with an ice storm.

Aurora0001

Nice to see you still have time to join the chat though ;)

Ice storm?

Wow

anonymous2

12:15

@Aurora0001 Freezing rain.

When the temperature goes up just above freezing after a cold spell and rains, the rain freezes on everything it touches.

So you end up with trees that weigh twice as much as they ought to (good for breaking branches & trunks) and driveways that are ice-rinks...

Aurora0001

Sounds fun

anonymous2

It is. Honestly.

It just creates a lot of work.

Aurora0001

The best we get in the UK is a little bit of frost on the pavement

anonymous2

Just like the 1-2 feet of snow we're supposed to get today.

@Aurora0001 Yikes! Poor folks!

Aurora0001

Indeed, it's just like (0.01 inches) of snow!

anonymous2

12:18

@Aurora0001 I guess you don't need a self-propelled snow-blower... ;)

Aurora0001

I need one that creates snow :P

anonymous2

@Aurora0001 We do have those, actually.

We use them on ski slopes.

But they don't work much above freezing.

And above freezing, they have to have chemicals added to the water so that it will freeze.

Aurora0001

Well, it's about 7 degrees, so no luck there then

anonymous2

Celcius?

Aurora0001

Celsius of course, anyone who uses Fahrenheit is evil

3

anonymous2

12:20

Duh, of course.

Aurora0001

Don't tell the Americans :P

anonymous2

@Aurora0001 Wouldn't have said it quite so strongly, but anyhow...

@Aurora0001 Americans = people from North or South America?

;)

@Aurora0001 I thought you settled that one back in 1783.

Aurora0001

Well, don't tell the inhabitants of the USA then

They don't like any unit of measurement that contains logic (especially metric)

anonymous2

@Aurora0001 United Statians.

;)

Anyhow, see you around, I have approximately 1.8 decimeters of snow to remove.

Aurora0001

Argh, why are people abusing inline code as text formatting?

@anonymous2 Enjoy

We all know you mean 1.8 x 10^-1 m of snow though

Also @anonymous2 when you get back, check if you'll be able to attend the Site Scope Chat Event - if it's a bad time for you I can always move it

Ghanima

13:00

@Aurora0001 there comes your hat for the first edit war on IoT

Aurora0001

@Ghanima it's not an edit war! It's just... evolving

Anyway, it seems to be Meta.SE consensus that abusing code formatting is bad

Ghanima

yes, and it probably is

Aurora0001

13:44

Hooray! Silver badge!

Helmar

13:55

Most of all, it's ugly as hell

Congrats on the badge

Aurora0001

Also, looks like @anonymous2 is really winning in the vote league table

iot.stackexchange.com/users?tab=Voters&filter=all

Ghanima

@Aurora0001 enthusiast? cheater!

Aurora0001

@Helmar thanks, I'm surprised you didn't get more answer badges honestly

@Ghanima nope

Enlightened

From now, the official address shall be His Madnificence Aurora0001, the Enlightened One.

Ghanima

His Madnificence, Aurora, First of his Name, Lord of IoT, the Enlightened One, Protector of the chat.

Helmar

My stuff is collectively sitting at 8-9 votes apparently ;)

Aurora0001

14:01

In other news, the downwards trend for traffic is continuing

quantcast.com/iot.stackexchange.com#trafficCard

The promotion at the SmartThings Community didn't have much effect

Helmar

Well, it was officially expected

"Please note that with the anticipated slowdown in traffic during the end-of-year holidays, we will..."

Aurora0001

yeah, but I was expecting it to rebound a little bit

Looks like it might be no cause for concern actually - looks like all SE sites had the same slowdown yesterday

Bence Kaulics

14:21

We shall wait the new year, and publicness as "Eventually, 90% of a site's traffic should come from search engines.".

Henry WH Hack v2.0

I am taking a risk by posting this:

Q: How to change the amazon echo wake word?

Is it possible to change the amazon's echo wake word form "Alexa" to something else? If so how can I do that?

We need to take risks in life!

I think.

Aurora0001

Good question, I had considered posting that

Henry WH Hack v2.0

You see taking risk is good as long is it is not dangerous!

@Aurora0001 ;)

Aurora0001

14:36

Wham! Answer complete.

Henry WH Hack v2.0

:O

Aurora0001

I always feel guilty when my answer is mostly quoting, but why rewrite what's already written by someone else?

With attribution, of course ;)

Helmar

14:50

That question is not included in this

Not sure if I made the best categories though

Ghanima

we need more of the Hm questions

2

Aurora0001

@Helmar was that manual then?

Is there any way you can download a dump of all the questions - if so I might do some machine learning magic to see if I can find anything interesting

Helmar

Oh yeah, that was the mobility-connectivity question about malaysia

@Aurora0001 Yeah, I'm in a train and my book ended an hour ago ;)

So that's not tags or something, that's a totally subjective categorization :)

Aurora0001

This is a shame - doesn't look like the question dumps are public yet

Looks like I can get a goldmine of data from the API

Time to put my Python skills to good use

Why is scikit-learn 200MB to install?

"Incidentally, Internet companies do use user-retention models that look a heck of a lot like epidemic models" - so, in effect, companies like SE want to infect us with their disease

Helmar

15:14

I'm vaccinated.

Aurora0001

Nice

Helmar

Yeah, that's a better clustering

Aurora0001

So, unsurprisingly, IoT is mostly about... the Internet (and protocols)

Helmar

Third category is a bit fuzzy though and will be hard to define properly

Aurora0001

Let's see if I can set up a clustering algorithm and see if that agrees with you @Helmar

Helmar

15:18

The other categories however could be quite easily defined

Aurora0001

I must admit I've never (successfully) done text clustering before

Helmar

That'd be interesting, especially because I did it completely by hand.

I guess some of the MQTT questions could wander off to other categories

Bence Kaulics

Hehe, MQTT questions are on the lead.

Aurora0001

Another interesting thing I could try: can I create an algorithm to predict the percentage upvotes you'll get?

Helmar

Phew, that's gotta have a lot of parameters xD

Aurora0001

15:20

Also, prepare yourself for some awesome XKCD-style graphs

Because matplotlib allows you to create them!

matplotlib.org/xkcd/examples/showcase/xkcd.html

Helmar

Anonymous is at 294 votes

Aurora0001

And you say I voted on 101% of things

Helmar

Nice, XKCD plots

Well, he switched gears ;)

Ghanima

matplotlib FTW!

Aurora0001

All 130 questions are now safely downloaded using Python

Oooh, Python f-strings now work

Awesome

Now I've written a script to strip away the HTML

Only about 5 more scripts to go before I get some useful output!

Bence Kaulics

15:48

The road is the interesting and not the destination. :D

Aurora0001

It'd be just my luck for it to say '1 cluster found'

Helmar

A: Let's discuss the site scope in chat!

Preliminary, manual question category analysis I made a quick analysis of the questions on site so far. I grouped them into seven categories. Category descriptions follow below.1 Categories How to do X? (End User IoT Questions) Generally speaking, those questions include everything about re...

Aurora0001

16:16

Well, I got some sort of result

The computer thinks these topics exist:

- iot devices device internet things power classifies network data

That's topic number 1

Hold on, I'll pastebin it - probably easier

pastebin.com/NJCV6Txz

Helmar

hm

So #1 is products

Aurora0001

#8 seems to be 'gas meters'

#9 is basically just 'ifttt'

Helmar

#2 is mqtt

#7 geo-tagging

Aurora0001

#3 is Echo

#5 is Thread

#4 is 'building devices' I think

#6 is best practices

Helmar

#6 is update best practices, I guess

#4 includes the fireplace safety question for sure, that wasn't about building, iirc

Aurora0001

16:24

I'll see if I can get it to 'justify' why it created each topic

Helmar

In prose please xD

Aurora0001

If only it was that smart...

Ghanima

fancy

Aurora0001

I've told it to find 5 topics now - seems a little bit more useful

pastebin.com/HSmkWp67

Ghanima

client messages server application clients connection accepts unsubscribe subscriptions subscribes

hm, uhm

so clients doing clientsy stuff subribing and unsubscribing it is

Aurora0001

16:30

Well, I can safely say that a computer is not very good at topic extraction.

Ghanima

lets, uhm, use helmar for that

Aurora0001

from helmar import TopicExtractor

Ghanima

NameError

Aurora0001

Fine...

pip install helmar

Also, that program is now called topic-extractify.py

Helmar

My train is back online :)

"device fantastic press confusion"

Fantastic indeed

Aurora0001

16:35

More confusion :P

AHA

This worked a lot better

pastebin.com/z3gdrMdu

I would draw you a pretty graph, but unfortunately this is in about 5000 dimensions

Helmar

It considers wi and fi different words

Aurora0001

Yeah, that's a bit off

Helmar

16:51

Arkansas is supoenaing Amazon

They want Echo data

npr.org/sections/alltechconsidered/2016/12/28/507230487/…

Found it in English

Aurora0001

I'll read that in a sec

It seems like my predictor is working

Let's see if I can count how popular each category is now

Aurora0001

17:17

The clusterer works nicely, and it now sorts each post into the category that it thinks it's in

There are a few oddities with it though

And it seems to be a bit non-deterministic

Helmar

Too many tunnels

So what's the most popular category?

Aurora0001

let me show you what I've done so far - it's quite interesting actually

People really seem to hate Google Home/Raspberry Pi questions

I think it's heavily distorted by these posts though:

Q: How to Enhance the Voice Recognition on Raspberry Pi controlling Smart Home Devices

I have a Raspberry Pi running Jarvis, a personal IA that I can use with my voice to control my smart home devices. However, the voice recognition is far from perfect. They have a list of speech-to-text (STT) services that I could use. Should I be worried about privacy if a choose a better servi...

Q: Are there any IoT devices with fully open source hardware?

Raspberry Pi is broadly used for IoT and there is a lot of software for it. But I would like to know about any completely open source design, including software and hardware (PCB, not components). I heard about Banana Pi but I'm not sure if it's completely open source or if other alternatives ex...

Helmar

Can you exclude closed questions?

Aurora0001

Give me a sec

Ghanima

17:36

@Aurora0001 as it is said: what is the meaning of this?

Aurora0001

@Ghanima Which bit do you need me to explain?

Helmar

Damn shame that programm didn't create a fruit category with all those apples, raspberries and bananas xD

Ghanima

@Helmar that probably means it's broken

completely undeterministic (and not just a little as the Oh Allmighty tries to put it)

Aurora0001

@Helmar, this one excludes closed questions: pastebin.com/wUJ91UQE

Cluster #7 is the 'worst' one

@Helmar you have an interesting definition of seven: meta.iot.stackexchange.com/questions/163/…

Helmar

Holy shit, no idea what I counted there

And your cluster 7 is terrible 91% approval

Aurora0001

17:52

Looks like everyone loves MQTT - 100% upvoting

Helmar

It's very technical, I guess it's either ignore or upvote

Aurora0001

Going to add a metric which factors in views next

Helmar

I'll check back later, train is arriving :)

Aurora0001

Alright

This next metric is based on (upvotes - downvotes) / (views)

So in theory it should be a 'compellingness' measurement

Aurora0001

18:12

So, it seems that between 1 in 5 and 1 in 10 actually vote

Which is pretty normal, to be honest

10% would fit quite well for the 90-9-1 rule

Aurora0001

18:30

Question #28 from me is now published.

Oh dear, views have dropped below 70

Aurora0001

Opinion?

Aurora0001

That's definitely off-topic for SO

"Questions asking us to recommend or find a book, tool, software library, tutorial or other off-site resource are off-topic for Stack Overflow as they tend to attract opinionated answers and spam. "

Bence Kaulics

Yep. But how would we handle it here?

Aurora0001

Not sure to be honest, resource recommendations don't work that well here

This is a resource recommendation though and it's not closed:

Q: Is there a fully open source platform for IoT presentation and visualization?

I had decided to use the AWS IoT communications platform in order to talk with our sensors. However, when it comes to visualization, I was hoping it wouldn't be necessary to reinvent the wheel. As you can see in the above picture, the IoT framework connects to an application server. My previo...

web-services

Bence Kaulics

Yes that part should be edited out. But the question can be interpreted as "What IoT controllers are suitable to connect RaspPi with an application that uses websocket"

Maybe.

Little bit broad maybe.

Aurora0001

Would be helpful if they specified their use case

Aurora0001

20:56

Only 250 rep until I get the site analytics access, which will be really useful

But I probably won't get to 2500 before the privileges go up, sadly

Aurora0001

21:17

Well, this is disappointing: winterbash2016.stackexchange.com/leaderboard/…

Community has more hats than me.
