On the string propaganda

Heeellll yeah

Bestie is an entire PLACE

I look at those guys and let me tell you the soul of that thing ain't just in the puppet, it's in all the neurons carrying the thoughts and emotions, it's in the power rails that serve as the heart. All the memories in the memory conflux and all the numbers we see flicker across displays, the flux condensers, the puppet; a little avatar.

No way these massive machines see life the same way we do. They have their own experiences and senses and things they hold dear. A world we can't imagine, a way of living we couldn't even comprehend.

I could never tear an iterator apart to be just a puppet. Who am I to decide how's life supposed to be enjoyed or perceived?

You treat your creechurs however you want- I ain't gonna dictate that. But damn, hearing the thrums and buzzes of the linear systems rail? They are alive with so much power, these mechanical beasts are exactly what they should be.

So this ficlet-ish thing was inspired by @hydrachea, nsfw super genius extraordinaire, but also by the fact that in addition to Boothill's left eye being cybernetic, I like to hc even the parts of him that look human aren't fully natural. I mean the dude eats bullets, after all. I think he should also have vents in his mouth so he can literally blow smoke/steam, it would look super cool. Think Father Gascoigne or Studio BONES' Todoroki. We as a fandom deserve that!!

So anyway, of course, sometimes these vents get blocked up and need to be cleaned manually. Thankfully, Dan Heng is super helpful ☆

Like there's one day where Boothill is lazing around in the archives, fresh off a bounty and happily soaking up the luxury of the Astral Express after however long he's spent tracking his prey through all the dust and dirt with almost no rest.

Boothill likes it in the archives. It's not silent, but it's quiet. There's no music and only muffled voices from outside, but there's the hum of all the computer systems. It makes for a nice place to hide away and recharge when he's just finished exhausting himself.

And besides, Dan Heng is there.

Sometimes the two of them talk back and forth, but today it's mostly quiet...except for-

"I didn't know it was possible for you to get sick."

...Except for Boothill having to constantly clear his throat. That's the thing about your mark trying to flee into the desert. You either go after them and get sand everywhere (and even worse, sticky sand once it gets all bloody) or you wuss out and lose out on the bounty. Personally, Boothill likes being able to afford to eat.

"Grit's stuck in a vent somewhere, 'n' the usual maintenance ain't gettin' it. I'll prob'ly have ta manually dig it out." But later, when he's not laid out half asleep on Dan Heng's extra futon. Usually after a chase as long as this one took, he can shut down for almost a full day. He doesn't want to get up yet.

Something shadows over him, and reflex demands Boothill's eye open. Dan Heng steps around him on his way to some drawer built in the wall on the other side of the room or something. Boothill closes his eye again.

From under his hat he hears the sounds of rummaging, drawers sliding open and shut, the swish of a long coat. The shadow returns.

"Sit up, just momentarily. I have something to help." And Boothill groans a tired don't wanna, but he does it anyway, he hauls himself upright into a kneel. And then he sits up a little straighter because he realizes Dan Heng is standing right over him.

Dan Heng tells him "open your mouth," and Boothill's jaw pops open without his permission, without even a second thought, and hey, what protocol in there ok'd THAT?!?!

Before he can really unpack whatever the heck that just was, though, Dan Heng murmurs for him to say so if he needs them to stop, and then he's sliding a long, hard rod down Boothill's throat, tipped with some soft little brush he probably uses for all his fancy archival equipment.

Dan Heng tells him the handle of the brush is straight and can't be bent, he needs to move his head to be able to reach the vent in his throat. Boothill hums affirmatively; he can't do anything else with his mouth occupied.

Dan Heng's free hand holds him by his jaw, tilts it up slowly but firmly so he has to look straight up at him.

Boothill feels dizzy.

The cycle of blue blood through his artificial heart whirrs just a bit faster, his temperature sensor pings an internal alarm to warn for imminent overheating. Boothill curls his fingers into the guard over his knee as Dan Heng carefully brushes at the dust irritating him. All other sounds- the hum of running equipment, the occasional beep from the computers, the noise of the crew outside of this room- seem to pull away, until all Boothill can focus on is the steady and measured breathing from the man above him.

"Almost done."

Thank the aeons, maybe one of them likes him after all.

"Your tongue is in the way... I'm going to hold it down, ok?"

Nevermind.

The fingers holding his jaw curl around his chin, thumb slipping past open lips to dip into his mouth and pin down his tongue. One of his teeth catch on the digit, breaking skin just enough to bleed a drop where he can taste it. Dan Heng doesn't even flinch. Another temperature alarm pings off in his brain, then another, then another.

Boothill has never been shy about eye contact but oh, god, it nearly kills him when dull green irises flick away from their task and look down right at him as his mouth is held open. He quickly squeezes his own eye shut for some relief.

With his vision cut off, the rest of his senses automatically recalibrate to compensate. He can hear every breath even more distinctly now, every soft inhale and exhale, feel the strain in his neck, the softness of the brush, the hard floor beneath his knees, the hand holding his jaw and the fingerprints that feel like they should leave burns in his skin, the taste of Dan Heng heavy on his tongue-

Forget it, eye open, eye open!!

"Alright. There's one last pebble stuck."

Boothill had been trained to endure torture, back on his homeworld. It was part of being in a gang, part of being a bounty hunter.

Somehow, keeping himself quiet and still as Dan Heng inches the brush even further down the back of his throat is a profoundly similar experience.

The seconds tick by, Dan Heng's brow furrowing, face growing ever more concentrated and Boothill struggles not to watch him too closely, fights down the noise that suddenly tries to escape him as the brush withdraws-

"Swallow."

Stars and aeons, Dan Heng is going to be the death of him.

Boothill swallows. He feels it when the movement finally dislodges the loosened pebble from his vent.

His face feels shockingly cold now bereft of touch, even though Dan Heng's hands are always cool. He asks to see, and Boothill's mouth is already open again to show him, even as he belatedly realizes he could have just told him it had worked.

"Good." There's the slightest smile on Dan Heng's lips as he finally, mercifully, leans back out of his personal space, goes to put away the brush. "That should feel better now." Boothill spends a moment dizzy and dazed, feeling the need to blink spots out of his eye even though his vision is clear. He still hasn't moved off his knees.

What the fudge.

Chip-free wireless sensors could reduce environmental impact of electronic tags

A more sustainable new form of electronic tag could help reduce the vast environmental impact caused by single-use RFID technologies, researchers say. Engineers from the University of Glasgow have developed the new wireless tag system, which can identify objects and measure temperature without the use of microchips. Instead, the tags use inexpensive coils and a sensing material made from a form of silicon rubber called PDMS and carbon fibers. The coils, smaller than the ones found in credit cards, absorb electromagnetic signals from a hand-held reader using electromagnetic waves. The researchers say their new, less wasteful tags could help reduce the retail sector's reliance on RFID chips, which uses more than 10 billion tags each year. Most tags are used just once, and end up in a landfill without appropriate recycling of the electronics.

Das Schlafzimmer als Kühlschrank

Meine Mutter besteht darauf, jeden Morgen ihr Schlafzimmer zu lüften, indem sie entweder das Fenster oder die Tür nach draußen öffnet. Dann verlässt sie das Zimmer und vergisst das Thema. Stunden später, manchmal erst abends, merke ich, dass es in der Gegend ihrer Schlafzimmertür noch kälter ist als sowieso schon in diesem Teil des Hauses. Bisher haben wir das Problem durch Vorhaltungen (ich) und gute Vorsätze (die Mutter) zu lösen versucht. Aber als wir gemeinsam das Haus verlassen und ich beim Zurückkommen feststelle, dass die Schlafzimmertür nach draußen die ganze Zeit weit offen stand, sage ich: So geht es nicht weiter!

Ich bespreche das Problem mit meinen Geschwistern und mit dem Techniktagebuch-Redaktionschat mit der Bitte um einen "möglichst einfachen" technischen Weg. "Zusatzproblem: sie hört nicht gut, einen akustischen Alarm wird sie entweder nicht hören oder er wird sie sehr erschrecken (letzteres hat irgendwie mit den Hörgeräten zu tun)." Verschiedene Lösungen werden vorgeschlagen:

Esther: "Vielleicht kann sie einen wichtigen Gegenstand (Brille, Fernbedienung) auf das Fensterbrett vom offenen Fenster legen, damit sie zeitnah auf der Suche danach wieder am Fenster vorbeikommt."

Vorteil: angenehm untechnisch, wartungsfrei. Nachteil: Ans Hinlegen des Gegenstands müsste sie denken, und zwar jedes Mal.

Lennart: "Mir fallen da spontan Sensoren von Shelly ein, die man an Fenster/Tür klebt. Die funken den Zustand in die Shelly-Cloud und man kann z.B. einen Zwischenstecker damit verknüpfen, der sofort oder nach fünf Minuten eine Lampe einschaltet oder so. Vielleicht ist das schon way beyond 'möglichst einfach'. Aber immerhin muss man dafür keinen lokalen RasPi administrieren."

Volker: "Das ist ein Dauerthema bei uns. Insbesondere wenn abends Frau oder Tochter im Bad waren und mal kurz lüften, dann aber vergessen, das Fenster zu schließen und ich im Winter morgens bei 7° duschen muss. Ich hatte da die Idee, dass ein Sensor beim Öffnen prüft, welches Bluetooth-Gerät gerade am nächsten dran ist, und dann anhand der MAC-Adresse oder so weiß, wer 10 Minuten später vom Smarthome eine Benachrichtigung bekommen muss, das Fenster wieder zu schließen."

Mia Culpa: "Ich habe keine Ahnung, ob ein automatischer Fensterschließer mit Zeitschaltuhr helfen würde, aber ich gebe zu bedenken, dass u.a. diese Features ausgelobt werden: 'Verbesserte Schnurführung durch den Rollenbügel', 'Doppelte Reißkraft der Kolben-Schnur Einheit (verstärkte Einpressung und zusätzliche Verklebung)', 'Deutlich verbesserte Charakteristik der Zeiteinstellung mit der Einstellschraube'. Schau mal Pügumat (der hat allerdings keine Zeitschaltuhr)."

Volker: "Das Fenster ist dann aber nur 'zu' und nicht zu. Der Griff ist nicht gedreht und die Riegel nicht drin, das heißt, dass es ziehen wird und Einbrecher sich verarscht vorkommen, weil sie das Fenster nur aufdrücken müssen."

Ich denke ein bisschen nach und komme zu dem Schluss, dass es nicht der Öffnungszustand der Fenster ist, der einen Alarm auslösen sollte, sondern die Temperatur im Schlafzimmer. Im Sommer ist es ja egal, wenn das Fenster den ganzen Tag offen steht (okay, die Tür weniger, aber es ist eine Gegend ohne viele Einbrüche, und es gibt bei der Mutter auch nichts zu stehlen.)

Dann finde ich heraus, dass in Handys Temperatursensoren drin sind und es deshalb Apps gibt, die bei bestimmten Temperaturen Alarm schlagen können. Ich installiere so eine App auf dem alten Handy meiner Mutter und lege das Handy erst ins Schlafzimmer, dann vor die Tür und dann in den Kühlschrank. Überall zeigt die App 25 Grad an. Ich lösche die App und verwerfe den Plan wieder.

Lennart hat auch dafür eine Lösung, nämlich den "Shelly H&T": "Das ist noch einfacher als die Fenstersensoren, weil man es aus der Steckdose speisen kann (also nie Batterien leer) und es im Gegensatz zu den Fenstersensoren direkt WLAN spricht. Jetzt überlege ich bloß noch, ob es was braucht wie 'Alarm nur wenn die Differenz zu Zimmer B größer als x°C' oder ob es eine universell gültige Temperaturschwelle gäbe, die als Indikator ausreicht."

Das mit der Differenz zu Zimmer B wäre toll, denn dann würde das System auch im Frühling und im Herbst ohne Nachjustieren funktionieren. Letztlich ist es zu diesen Zeiten aber wohl nicht so wichtig – Hauptsache, mitten im Winter steht nicht den halben Tag das Fenster offen.

Esther: "Hast du denn irgendwo bei ihr schon einen raspi am laufen? Bei uns empfängt ja einer via Funk die Messdaten von den Wetterfühlern und schickt uns Telegram-Nachrichten, wenn es zB zu kalt in einem Raum wird. Man kann zB den CO2-sensor von TFA Dostmann mit USB an den raspi anschließen, oder man gibt dem raspi eine Antenne, damit der die gefunkten Daten von ganz normalen Wettersensoren abgreifen kann. Diese Wetterstationen senden ja einfach über irgendeine Funkfrequenz, auf der der raspi lauschen kann."

Das gefällt mir gut, denn einen Raspberry Pi gibt es im Haushalt schon, und Telegram-Nachrichten wären ideal, die würde meine Mutter mit nicht mehr als zwei, drei Stunden Verzögerung sehen. Den Bot dafür habe ich auch schon geschrieben.

Lennart: Ich habe Olimex-Mikrocontroller für mich entdeckt, auf denen kann man Tasmota installieren, alle möglichen Sensoren anschließen und das dann an einen RasPi (mit in meinem Fall IOBroker) weiterleiten. Ich habe das exemplarisch mal hier beschrieben: SR04, Tasmota, ESP32, MQTT und IOBroker – Schuetz-IT."

Undine: "Meine Idee dafür ist ganz untechnisch: Wenn sie vor diesem Fenster einen Vogelfutterplatz einrichten würde, ginge sie deswegen öfter zurück ins Zimmer. Mindestens um zu gucken, ob dort alles in Ordnung ist, noch nachgefüttert werden muss, auch mal ein Kernbeißer auftaucht u.ä. So würde es bei meiner Mutter funktionieren."

Bei meiner leider nicht. Vor dem Fenster ist schon ein Vogelfutterplatz. Man sieht ihn aber aus der Küche viel besser, er muss nur einmal pro Woche aufgefüllt werden und außerdem bin ich für seine Befüllung zuständig.

Am Ende ist es mein Bruder, der eine einfache Idee hat: Man kauft ein Kühlschrankthermometer mit einer Funkverbindung zwischen Sensor und Pieps-Gerät. Bei diesen Thermometern lassen sich die Grenzwerte des Piepsens frei einstellen (zwischen minus weißnichtgenau und plus 60 Grad). Dann piepst es zwar – was ich eingangs als Problem beschrieben hatte –, aber es piepst nicht im Schlafzimmer, wo die Mutter es niemals hören wird, sondern es piepst nahe an einem Ort, an dem sie sich oft aufhält. Hören wird sie es also, und das Problem mit dem möglichen Erschrecken nehme ich in Kauf, weil die Lösung so schön einfach ist.

Ich bestelle für 20 Euro ein Kühlschrankthermometer bei Ebay, stelle den Alarm-Grenzwert für die Schlafzimmertemperatur auf 9 Grad ein und klemme den Sensor an den Schlafzimmerspiegel. In einem ersten Test funktioniert es sehr gut. Da man ja beim Kühlschrank auch nicht sofort angepiepst werden möchte, wenn man nur mal kurz die Milch rausholt, bildet das Gerät einen Mittelwert über die letzten zehn Minuten und piepst erst, wenn dieser Mittelwert unter dem Grenzwert liegt. Das ist zufällig auch für den Lüftungszweck ideal.

Damit ist das Problem hoffentlich entweder behoben oder durch ein bequemeres ersetzt.

Update: Zwischenstand nach wenigen Tagen – es funktioniert genau wie erhofft und ist sehr befriedigend.

Ultracompact fiber-tip sensor achieves high sensitivity in magnetic field and temperature measurements

Magnetic field sensing plays a pivotal role in numerous fields of medical, transportation and aerospace. The optical fiber-based magnetic field sensor possesses outstanding characteristics of compactness, long-distance interrogation, low cost and high sensitivity, which has attracted intensive interest. However, the fiber-based magnetic field sensor is generally affected by the temperature perturbation. Recently, although the temperature crosstalk can be effectively eliminated by integrating multiple sensing elements, it is at the cost of increasing the size of the whole sensing components, and the different spatial location of multiple elements could cause the measurement errors in the multi-parameter discriminative sensing. In a new paper published in Light: Advanced Manufacturing, a team of scientists, led by Professor Limin Xiao from Advanced Fiber Devices and Systems Group, Key Laboratory of Micro and Nano Photonic Structures (MoE), Key Laboratory for Information Science of Electromagnetic Waves (MoE), Shanghai Engineering Research Center of Ultra-Precision Optical Manufacturing, School of Information Science and Technology, Fudan University, China, and co-workers have developed an ultracompact multicore fiber (MCF) tip probes for magnetic field and temperature discriminative sensing.
