“are you still watching?” – tailfix

drop in replacement for tail -F that asks you if you are still watching

Just like Laura I am also was having a moment when I stumbled across tailflix.

For those not understanding the reference: At the end of an episode you’ve watched on Netflix you will be shown another one, and so on, and so on. Until if you have not touched the remote at all for several episodes Netflix will ask you “Are you still watching?”.

N8.5 – Tokyu White

It always seems to me so much easier to meet a Hackers in Japan than anywhere else. Maybe social-gravity works different there. Or there are more of them.

Whatever the reason, I keep crossing paths with people that more or less deep-dive into topics and understand systems in ways and in details that you would normally not expect.

And todays example is a detail you would normally not think about:

The footbridge that was newly built in Shibuya was painted in N8.5. This is commonly known as “Tokyu White”…

“Tokyu White”, N8.5, … of course…if you would need a bucket of this you can order it online.

the future of (speech) podcasts

The Podlove project once again leads the way to improve the experience and the way we interact with knowledge and thoughts. With the most current announcement and introduction of transcription-support for podcasts. Click on it right now and try it yourself.

Fulltext-search. Listening to podcasts by reading them. This-is-amazing!

Transcripts are coming

Transcripts are an incredibly desirable thing to have for podcasts: they allow searching for specific parts, increase searchability by search sites when presented properly and they increase the accessibility of audio content significantly too.

However, transcripts have been considerably difficult to be created and used. Manually created transcripts are costly in terms of time and money and even if you spend the money there has been a lack of technical standards for storing and integrating transcripts into websites in a defined way.

This is now slowly changing: more and more automated speech-to-text systems are becoming available at reasonable costs and they are creating ever better transcripts with more and more languages being supported.
Still, automatic transcripts trail manually created transcripts in terms of accuracy, punctuation and so on but they are increasingly useful when they are primarily used for improving search results or helping you with your internal research when trying to find content in your older episodes.

New services are also coming up to deal with these problems by allowing users to quickly build on automatic transcripts and improve them manually in an assisted fashion. We will soon see a landscape of tools and services that will make creating transcripts easy and cheap enough for more and more podcasters so it’s time to come up with a good integration.

Last but not least, the WebVTT file format has become a de-facto common denominator for passing transcripts along, supporting time codes, speaker identification and a rudimentary set of meta data. While not perfect it’s enough to get a transcript infrastructure up and running and Podlove is leading the way.

Jimmy is hitting again

I joy! I just found out that James Euringer had produced a new album. You do not know Jimmy Urine?

Let’s start the introduction with the description of his current gig:

EURINGER is a counter-culture, surreal, psychedelic, art house, avant-garde, possibly posthumous concept project from Jimmy Urine of Mindless Self Indulgence fame. Featuring guest vocals from Grimes, Serj Tankian (System Of A Down), Gerard Way   (My Chemical Romance) and Chantal Claret (Morningwood) – and also staring Jimmy’s Mom and Dad for good measure! – the record is one  long song/musical/concerto, as if an underground movie was made for your ears. “I wanted it to sound as if Depeche Mode hired J. Dilla and DJ Premier to drop loops while Frank Zappa produced, and then I came in and shit all over it,“ said Jimmy.

Metropolis Record / Euringer

Here’s the most current album in safe-for-work version:

EURINGER – FUCK EVERYTHING (OFFICIAL SFW VIDEO)

Now there’s a whole album.

And it’s not the first one from this direction. You may have heard of Jimmys other band “Mindless Self Indulgence“.

To round things up: His wife, Chantal, is the singer of “Morningwood”. Like, you know, “n-th degree”-Morningwood.

the interesting bit about googles game streaming

In 2012 I’ve experienced streamed game play for the first time. I was a beta-user of the OnLive service which created a bit of fuzz back then.

Last week Google had announced to step into the game streaming business as well. They’ve announce Google Stadia as the Google powered game streaming platform. It would come with it’s own controller.

3 color variants

And this controller is the most interesting bit. We have seen video live streaming. We have seen and played streamed games. But every time we needed some piece of software or hardware that brought screen, controller and player together.

The Google Stadia controllers now do not connect to the screen in front of you. The screen, by all it knows, just shows a low-latency video/audio stream.

The controller connects to your wifi and directly to the game session. Everything you input with the controller will be directly sent to the Google Stadia session in a Google datacenter. No dedicated console hardware in between. And this will make a huge difference. Because all of a sudden the screen only is a screen. And the controller will connect to the “cloud-console” far-far away. As if it was sitting right below the screen. This will make a huge difference!

japanese puns?

Learning a new language is full of discoveries along the way!

As I am spending more time on learning the Japanese language the more different things seem to unlock. One of those things is the apparent fun Japanese companies have with puns/slight writing mismatches.

Like this one – I think (as I can not be 100% sure yet…learning!):

こわはたんの活わだ?or これはたんの活わだ?or こわはたんの汚わだ? or これはたんの汚わだ?

This is an advertisement in a supermarket for a laundry detergent. It is themed to an Anime called “Attack on Titan” – properly because the detergents name is Attack. So when I tried to make sense of the text I first read it wrong, of course.

Let’s look at it step-by-step:

I first started reading the Hiragana portion and make sense of it. There I made my first mistake which is to misread the first second character. For some reason my brain went for (wa) when I should have gone for (re).

Then I typed away further and came to the Kanji. I read a (katsu) when it in fact was a (kitanai).

Given that you’ve typed those into Google Translate you will get very interesting results. I had a good laugh by then:

I am not sure if this is on purpose or not – as I do not yet know if I am just making a mess on this or if this is intentionally done so that, given your level of Japanese reading and attention-spent reading it, you get very different and funny results.

Any Japanese readers that can add some explanations? Am I far off with the thoughts?

Digital assistant language teacher

Since a couple of months we are trying harder to learn a foreign language.

And as we excepted it is very hard to get a proper grasp on speaking the language. Especially since it is a very different language to our mother tongue.

And while comfortably interacting with digital assistants around the house every day in english and german the thought came up: why don’t these digital assistants help with foreign language listening and speaking training?

I mean Google Assistant answers questions in the language you have asked them. Siri and Alexa need to know upfront in which language you are going to ask questions. But at least Alexa can translate between languages…

But with all seriousness: Why do we not already have the obvious killer feature delivered? Everyone could already have a personal language training partner…

How to get me to actively avoid your products

It is a simple one step process: shove unasked advertising in my face. Bonus points for loud full blast audio right of the start.

If I ever see unasked advertising that tried to be sneaky or not do sneaky I am going to block it without noticing from whom or for what it was.

But when it’s shown so often and is so intrusive that I take note of your brand. That brand is not considered for future business anymore.

That is especially for services where I am the product paying with my data.

reward driven speed limits

As you might know I am living in Germany. Germany is the one country where you have some roads that are legally not having any speed limit whatsoever. If the circumstances allow to safely drive 250 km/h you are allowed to do so. It’s up to the drivers judgement.

Now as much as this is a great thing of personal freedom it also has some negative side effects on the climate.

Your car is burning a lot more fuel when driving those kind of speeds. And a lot meaning that it resembles more an exponential curve than a linear line. Rule of thumb: 2x the speed is more than 4x the consumption.

Ever once in a while people start discussing about a general speed limit for Germany – as every other country has it. Some talk about 160 km/h, some about 120 km/h.

The motivations are diverse: climate, resource use, safety, …

In any case additional limits would need to be enforced. More speed traps…

A.Savin (Wikimedia Commons · WikiPhotoSpace)

What if things would be handled differently?

How about this:

Politics would introduce a “best speed lottery”. On every street without a speed limit there would randomly be speed controls and speed traps. Those who follow the best practices of driving … Let’s say 120 km/h… Would be rewarded when randomly photographed. The reward would be a tax discount on car tax and/or gas tax and one ticket put into the countries lottery pool. Once a quarter a new electric car or similar would be given to a random winner.

What would you think would make people drive slower in their own motivation?

Japan related YouTube channels I regularly watch

If you ask me for an estimate on the main sources of entertainment we use in our household I would say it’s easily 80% YouTube these days. Mainly we’re watching the content created by small independent content creators while working out or during dinner.

None of this consumption is through the YouTube website or any official clients (like the abomination pre-installed on the TV) but through a carefully handcrafted series of scripts that watch certain playlists and download everything appearing new there automatically to the house in best quality. This then can be watched at any time from any TV in the house.

The playlists that are being monitored are either those directly curated by the YouTube channels or a playlist that get’s filled directly by us from recommendations / social media links.

So here are some recommendations from our heavy-rotation list:

Some more “special ones” – Musashi-Kosugi Station is the station at my preferred home-base when in Tokyo. I like the more off-the-center vibe of Musashikosugi and this is the main station live cam there:

This would not be a complete list without this: Nippon Wandering TV is one of several channels that do one thing: walk or cycle through Japan and record it. Simple, eh? – This stuff is playing as “screensaver” on every screen in the house when not used to watch anything else:

blog maintenance – status

A bit of feedback is in on the plan to revitalize this blog. Thanks for that!

I have spent some more time this weekend on getting everything a bit tidied up.

There is the archive of >3.000 posts that I plan to review and re-categorize.

There is the big number of comments that had been made in the past and that I need to come up with a plan on how to allow/disallow/deal with comments and discussions in general on this website.

There is also the design and template aspects of this website. I switched to a different template and started to adjust it so that it shall make access to the stream of posts as easy as possible. Until then you need to wait or contact me through other means. But contacting is another post for another time.

resilvering …

The last Ubuntu kernel update seemingly kicked two hard disks out of a ZFS raidz – sigh. With ZFS on Linux this poses an issue:

Two hard drives that previously where in this ZFS pool named “storagepool” where reassigned a completely different device-id by Linux. So /dev/sdd became /dev/sdf and so on.

ZFS uses a specific metadata structure to encode information about that hard drive and it’s relationship to storage pools. When Linux reassigned a name to the hard drive apparently some things got shaken up in ZFS’ internal structures and mappings.

The solution was these steps

  • export the ZFS storage pool (=taking it offline for access/turning it off)
  • use the zpool functionality “labelclear” to clear off the data partition table of the hard drives that got “unavailable” to the storage pool
  • import the ZFS storage pool back in (=taking it online for access)
  • using the replace functionality of zpool to replace the old drive name with the new drive name.

After poking around for about 2 hours the above strategy made the storage pool to start rebuilding (resilvering in ZFS speak). Well – learning something every day.

4+ hours to go.

Bonus: I was not immediately informed of the DEGRADED state of the storage pool. That needs to change. A simple command now is run by cron-tab every hour.

zpool status -x | grep state: | tr –delete state: |mosquitto_pub -t house/stappenbach/server/poppyseeds/zpool -l

This pushes the ZFS storage pool state to MQTT and get’s worked on by a small NodeRed flow.

taking the social stream back to this blog

I am currently in the process of reducing my presence on the usual social networks. Here is my reasoning and how I will do it.

Facebook, Twitter, Instagram and alike are seemingly at the peak of their popularity and more and more users get more and more concerned about how their data and privacy is handled by those social networks. So am I.

Now my main concern is not so much on the privacy side. I never published anything on a social network – private or public – that I would not be published or freely distributed/leak. But:

I have published content with the intention that it would be accessible to everyone now and in the future. The increasing risk is that those publishing platforms are going to fade away and thus will render the content I had published there inaccessible.

My preferred way of publishing content and making sure that it stays accessible is this website – my personal blog.

I am doing this since 2004. The exact year that Facebook was founded. And apparently this website and it’s content has a good chance of being available longer than the biggest social network at the present time.

So what does this mean? 3 basic implications:

  1. I will become a “lurker” on the social networks. Now and in the future.
  2. All comments and reactions I will make will be either directly in private or through my personal website publicly available and linkable.
  3. I will minimize my footprint on the social networks as much as possible. This for example means: If I use Twitter, all tweets will live 7 days and automatically be removed after this time. Deleting your tweets automatically is something others do as well.

As you can see: This is not about a cut or abstinence. I get information out of social networks, tweet message flows. But I do not put any trust in the longevity of both the platforms and the content published there.

The next steps for me will be a complete overaul of this website. Get everything up to current standards to streamline my publishing process.

Expect a lot of content and change – and: welcome to my blog!

Converting ひらがな to “hiragana” and カタカナ to “katakana” – Romaji command line tool

I had this strange problem that my car was not able to display japanese characters when confronted with them. Oh the marvels of inserting a USB stick into a car from 2009.

stupid BMW media player without proper font

Now there’s no real option I know of without risking to brick the car / entertainment system of the car to get it to display the characters right.

Needless so say that my wifes car does the trick easily – of course it’s an asian car!

Anyway. I wrote a command line tool using some awesome pre-made libraries to convert Hiragana-Katakana characters to their romaji counterpart. 

You can find it on github: https://github.com/bietiekay/romaji 

Join me implementing a neural network to improve accuracy of an OpenSource indoor location tracking system

To all techies reading this:

GIST: I am looking for interested hackers who want to help me implement a neural network that improves the accuracy of bluetooth low energy based indoor location tracking.

Longer version:

I am currently applying the last finishing touched to a house wide bluetooth low energy based location tracking system. (All of which will be opensourced)

The system consists of 10+ ESP-32 Arduino compatible WiFi/Bluetooth system-on-a-chip. At least one per room of a house.

These modules are very low powered and have one task: They scan for BLE advertisements and send the mac and manufacturer data + the RSSI (signal strength) over WiFi into specific MQTT topics.

There is currently a server component that takes this data and calculates a probable location of a seen bluetooth low energy device (like the apple watch I am wearing…). It currently is using a calibration phase to level in on a minimum accuracy. And then simple calculation matrices to identify the most probable location.

This all is very nice but since I got interested in neural networks and KI development – and I think many others might as well – I am asking here for also interested parties to join the effort.

I do have an existing set-up as well as gigabytes of log data.

I know about previous works like „Indoor location tracking system using neural network based on bluetooth

Now I am totally new to the overal concepts and tooling and I start playing with TensorFlow right now.

If you want to join, let me know by commenting!

making your home smarter use case #14 – prevent fires while charging LiPo batteries

Did you know how dangerous Lithium-Polymer batteries can be? Well, if not treated well they literally burst in flames spontaneously.

So it’s quite important to follow a couple of guidelines to not burn down the house.

Since I am just about to start getting into the hobby of FPV quadcopter racing I’ve tried follow those guidelines and found that the smart house can help me tracking things.

Unfortunately there are not a lot of LiPo chargers available at reasonable price with computer interfaces to be monitored while charging/discharging the batteries. But there are a couple of workarounds I’ve found useful.

  1. a proper case. I’ve got myself one of those “Bat-Safe” boxes that fit a couple of battery packs and help me store them safely. Even if one or many burst into flames the case is going to contain any heat and fire as good as possible and with the air / pressure filter it’ll hopefully get rid of most of the very nasty smoke (I hear). Cables go into it, so the actual charging process takes place with everything closed and latched.
  2. the obvious smoke detector which is on it’s own connected to the overall fire alarm is mounted on top, like literally on top. It’ll send out the alert to all other smoke alarms in the house making them go beep as well as sending out high priority push notifications to everyone.
  3. an actual camera is monitoring the box all the time calling on alerts if something is fishy (like making sound, smoke, movement of any sort). When charging is done the charger will beep – this is being caught by the cameras microphones and alerts are sent out.
  4. the temperature inside the case is monitored all the time. The surrounding temperatures are usually pretty stable as this case is stored in my basement and as the charging goes on the temperatures inside the case will climb up and eventually level out and fall when charging / discharging is done. Now the system basically will look at the temperatures, decide wether it’s rising of falling and alerting appropriately.

There’s a couple more things to it, like keeping track of charging processes in a calendar as you can see in the flowchart behind all the above.

making your home smarter use case #13 – correlations happen

There are a lot of things that happen in the smart house that are connected somehow.

And the smart house knows about those events happening and might suggest, or even act upon the knowledge of them.

A simple example:

In our living room we’ve got a nice big aquarium which, depending on the time of the day and season, it is simulating it’s very own little dusk-till-dawn lightshow for the pleasure of the inhabitants.
Additionally the waterquality is improved by an air-pump generating nice bubbles and enriching the water with oxygen. But that comes a cost: When you are in the room those bubbles and the hissing sound of the inverter for the “sun” produces sounds that are distracting and disturbing to the otherwise quiet room.

Now the smart home comes to the rescue:

It detects that whenever someone is entering the room and staying for longer, or powering up the TV or listening to music. Also it will log that regularly when these things happen also the aquarium air and maybe lights are turned off. Moreso they are turned back on again when the person leaves.

These correlations are what the smart house is using to identify groups of switches, events and actions that are somehow tied together. It’ll prepare a report and will recommend actions which at the push of a button can become a routine task always being executed when certain characteristics are lining up.

And since the smart house is a machine, it can look for correlations in a lot more dimensions a human could: Date, Time, Location, Duration, Sensor and Actor values (power up TV, Temperature in room < 22, Calendar = November, Windows closed => turn on the heating).

“making your home smarter” – use case #12 – How much time do I have until…?

Did you notice that most calendars and timers are missing an important feature. Some information that I personally find most interesting to have readily available.

It’s the information about how much time is left until the next appointment is coming up. Even smartwatches, which should should be jack-of-all-trades in regards of time and schedule, do not display the “time until the next event”.

Now I came across this shortcoming when I started to look for this information. No digital assistant can tell me right away how much time until a certain event is left.

But the connected house also is based upon open technologies, so one can add these kind of features easily ourselves. My major use cases for this are (a) focussed work, plan quick work-out breaks and of course making sure there’s enough time left to actually get enough sleep.

As you can see in the picture attached my watch will always show me the hours (or minutes) left until the next event. I use separate calendars for separate displays – so there’s actually one for when I plan to get up and do work-outs.

Having the hours left until something is supposed to happen at a glance – and of course being able to verbally ask through chat or voice in any room of the house how long until the next appointment gives peace of mind :-).

 

“making your home smarter”, use case #11 – money money money

The Internet of Things might as well become your Internet of Money. Some feel the future to be with blockchain related things like BitCoin or Ethereum and they might be right. So long there’s also this huge field of personal finances that impacts our lives allday everyday.

And if you get to think about it money has a lot of touch points throughout all situations of our lifes and so it also impacts the smart home.

Lots of sources of information can be accessed today and can help to stay on top of the things going on as well as make concious decisions and plans for the future. To a large extend the information is even available in realtime.

– cost tracking and reporting
– alerting and goal setting
– consumption and resource management
– like fuel oil (get alerted on price changes, …)
– stock monitoring alerting
– and more advanced even automated trading
– bank account monitoring, in- and outbound transactions
– expectations and planning
– budgetting

After all this is about getting away from lock-in applications and freeing your personal financial data and have a all-over dashboard of transactions, plans and status.

“making your home smarter”, use case #10 – Fire and Water alarm system

Water! Fire! Whenever one of those are released uncontrolled inside the house it might mean danger to life and health.

Having a couple of fish and turtle tanks spread out in the house and in addition a server rack in the basement it’s important to know when there’s a leak of water at moments notice.

As the server-room also is housing some water pumps for a well you got all sorts of dangers mixed in one location: Water and Fire hazard.

To detect water leaks all tanks and the pumps for the well are equipped with water sensors which send out an alerting signal as soon as water is detected. This signal is picked up and pushed to MQTT topics and from there centrally consumed and reacted upon.

Of course the server rack is above the water level so at least there is time to send out alerts while even power is out for the rest of the house (all necessary network and uplink equipment on it’s own batteries).

For alerting when there is smoke or a fire, the same logic applies. But for this some loud-as-hell smoke detectors are used. The smoke detectors interconnect with each other and make up a mesh for alerting. If one goes off. All go off. One of them I’ve connected to it’s very own ESP8266 which sends a detected signal to another MQTT topic effectively alerting for the event of a fire.

In one of the pictures you can see what happened when the basement water detector did detect water while the pump was replaced.

“making your home smarter”, use case #9 – weights about to drop

A lot of things in a household have weight, and knowing it’s weight might be crucial to health and safety.

Some of those weight applications might tie into this:

– your own body weight over a longer timespan
– the weight of your pets, weighed automatically (like on a kitty litter box)
– the weight of food and ingredients for recipes as well as their caloric and nutrition values
– keeping track of fill-levels on the base of weights

All those things are easily done with connected devices measuring weights. Like the kitty-litter box at our house weighing our cat every time. Or the connected kitchen-scale sending it’s gram measurements into an internal MQTT topic which is then displayed and added more smarts through an App on the kitchen-ipad consuming that MQTT messages as well as allowing recipe-weigh-in functions.

It’s not only surveillance but pro-active use. There are beekeepers who monitor the weight of their bee hives to see what’s what. You can monitor all sorts of things in the garden to get more information about it’s wellbeing (any plants, really).

“making your home smarter”, use case #8 – it’s all about the power consumption

Weekend is laundry time! The smart house knows and sends out notifications when the washing machine or the laundry dryer are done with their job and can be cleared.

Of course this can all be extended with more sensory data, like power consumption measurements at the actual sockets to filter out specific devices much more accurate. But for simple notification-alerting it’s apparently sufficient to monitor just at the houses central power distribution rack.

On the sides this kind of monitoring and pattern-matching is also useful to identify devices going bad. Think of monitoring the power consumption of a fridge. When it’s compressor goes bad it’s going to consume an increasing amount of power over time. You would figure out the malfunction before it happens.

Same for all sorts of pumps (water, oil, aquarium,…).

All this monitoring and pattern matching the smart house does so it’s inhabitants don’t have to.

“make your home smarter”, use case #7 – hear that doorbell ringing!

We love music. We love it playing loud across the house. And when we did that in the past we missed some things happening around.

Like that delivery guy ringing the front doorbell and us missing an important delivery.

This happened a lot. UNTIL we retrofitted a little PCB to our doorbell circuit to make the house aware of ringing doorbells.

Now everytime the doorbell rings a couple of things can take place.

– push notifications to all devices, screens, watches – that wakes you up even while doing workouts
– pause all audio and video playback in the house
– take a camera shot of who is in front of the door pushing the doorbell

And: It’s easy to wire up things whatever those may be in the future.

“make your home smarter”, use case #6 – calendars and scheduls

So how do you manage all these sensors and switches, and lights, and displays and speakers…

One way has proven to be very useful and that is by using a standard calendar. 
Yes, the one you got right on your smartphone or desktop.

A calendar is a simple manifestation of events in time and thus it can be used to either protocol or schedule events.

So the smart house uses calendars to:

  • schedule on/off times for switches, alarms, whatever can be switched
  • notes down locations and can react upon locations on schedule or when members of the household arrive/leave those locations based on calendar events
  • reminds members in the house on upcoming events
  • protocols media playback (what song,…) for later search
  • lets members of the house set events through different means like voice, smartphone, …

So what am I using this calendar(s) for? Simple. It’s there to track travelling since I know when I was where by simply searching the calendar (screenshot). It’s easy to make out patterns and times of things happening since a calendar/timeline view feels natural. Setting on/off times and such is just a bliss if you can make it from your phone in an actual calendar rather than a tedious additional app or interface.

And of course: the house can only be smart about things when it has a way to gather and access that data. Reacting to it’s inhabitants upcoming and previous events adds several levels of smartness.

“make your home smarter”, use case #5 – the submarine light (it’s red!)

We all know it: After a long day of work you chilled out on your bean bag and fell asleep early. You gotta get up and into your bed upstairs. So usually light goes on, you go upstairs, into bed. And there you have it: You’re not sleepy anymore.

Partially this is caused by the light you turned on. If that light is bright enough and has the right color it will wake you up no matter what.

To fight this companies like Apple introduced things like “NightShift” into iPhones, iPads and Macs.

“Night Shift uses your computer’s clock and geolocation to determine when it’s sunset in your location. It then automatically shifts the colors in your display to the warmer end of the spectrum.”

Simple, eh?. Now why does your house not do that to prevent you being ripped out of sleepy state while tiptoeing upstairs?

Right! This is where the smart house will be smart.

Nowadays we’ve got all those funky LED bulbs that can be dimmed and even their colours set. Why none of those market offerings come with that simple feature is beyond me:

After sunset, when turned on, default dim to something warmer and not so bright in general.

I did implement and it’s called appropriately the “U-Boot light”. Whenever we roam around the upper floor at night time, the light that follows our steps (it’s smart enough to do that) will not go full-blast but light up dim with redish color to prevent wake-up-calls.

The smart part being that it will take into account:

– movement in the house
– sunset and dawn depending on the current geographic location of the house (more on that later, no it does not fly! (yet))
– it’ll turn on and off the light according to the path you’re walking using the various sensors around anyways
