Kleinanzeigen ist einfach Rotz. Wenn man die App auf dem Phone hat und sich dann auf dem Desktop einloggen will, geht es nicht. Loggt man sich auf der App aus und wieder ein, auch nach cache wipe (selbe IP), geht es komischerweise doch, nachdem man nen 2FA Code per SMS (!) auf dasselbe fucking Phone (!) bekommt. Entweder deliberate Design choice, um die Leute auf die App (mit Werbung) zu knechten, oder einfach nur Unfähigkeit. Beides ist absolut unterirdisches Geschäftsgebahren.

@livia@sciences.social in einem Land, in dem der Durchschnittshaushalt noch 50k Leitungen "in Ordnung"/"völlig ausreichend" findet, würde ich als Konzern auch keinen Anlass sehen, für Ottonormies mehr als 1G überhaupt anzubieten. Alles dazu zu aktualisieren, neue Strukturen in der Software etc. einzurichten kostet vermutlich nur, ohne nennenswertes Einkommensplus.

This text by @Koenfucius@mastodon.social is short sighted, and, dare I say, naive. Explaining surge pricing with "getting closer to the real value" is mystifying the whole process in a "invisible hand" kind of way. Yet, in practice, it is pretty easy to explain: 1) Surge pricing is an easy way of extracting more money from the same resource base, it maximises revenue across the demand/supply curve. 2) The reason people hate it is because it is inherently unfair. Access is not determined by supply, but by monetary resources which often are outside one's control to a large degree. 3) The real value of something is often way beyond the price of an object. Think about things you have to buy but hate doing so (clothes for example in my case). If clothes shops would start surge pricing, it would effectively render my personal value of clothes even less than before. Value is a shit construct, especially when including it in weird moderating mechanics into transactional processes. It would be easier to explain such processes with Desirability and Affordability graphs. https://koenfucius.substack.com/p/the-value-of-everything

@benchmark@wien.rocks absoluter Quatsch. Deutsche Ingenieursprodukte sind und waren Weltspitze. Chemie/Pharma ist ebenso einer unserer besten Sektoren. In Solar (wie im OP angedeutet) waren wir bis 2010 Weltmarktführer. Das Problem ist die Produktion zu kompetitiven Preisen. Asien unterbietet uns da einfach um Welten.

Ich finde es immer wieder amüsant wie wir in Deutschland politisch einfach den Solar-Boom bewusst in die Tonne getreten haben und die Politik jetzt versucht, das fossile Autobusiness erfolglos zu retten. Hätten wir A, bräuchten wir B nicht. Jetzt haben wir den Schaden. Jobs gehen verloren, aber ohne Auffangindustrie. Und auf einmal müssen alle "mehr arbeiten" und "mehr Selbstverantwortung wagen".

Ich würde "danke CDU" sagen, wenn sie nicht die gesammelte Scheiße, die sie selbst jahrzehntelang angestaut hat, an der gesamten Bevölkerung auslassen würde.

Abgesehen von allem was mit dem "Reformpaket" der BReg falsch ist (so ungefähr das meiste), ist es erstaunlich, wie wenig denen klar ist, was das für ein politisches Todesurteil darstellt. Alle "Missstände", die Merz bisher kritisiert hat (hoher Krankenstand, hohe Arbeitslosenzahlen etc) werden durch diese Maßnahmen garantiert schlechter (sogar messbar). Nach Goodhart's Law werden Target-Kennzahlen normalerweise von obn gesetzt und von der Basis manipuliert. Hier wird die Kennzahl aktiv von oben manipuliert, aber in die Richtung, die dieselbe Partei eigentlich nicht will. Dümmer geht's kaum. Bitte schreibt euren Abgeordneten, dass sie dagegen stimmen sollen, insbesondere wenn sie von der SPD sind. Ich habs getan.

@JuenniausUebach@mastodon.social @blind_mapmaker@eldritch.cafe @Mela@zusammenkunft.net du scheinst keine Behinderung zu haben. Lass dir mal von jemandem mit einer solchen (hallo!) erzählen, warum dein Post absolut hirnrissig ist. Das Problem bei solchen "Argumenten" ist immer (und wir haben da noch kein Gegenbeispiel gesehen in der Geschichte), dass sie alle möglichen Sekundärfolgen nach sich ziehen. Einerseits werden Behinderte durch solche sachargumente (können wir uns nicht leisten etc) in ihrer Wertigkeit unter alle anderen gestellt. Das öffnet Tür und Tor für Ressentiments von Menschen, die diese Dinge dann für legitim halten. Wenn sich das gesellschaftlich verbreitet oder von gewissen Akteuren gefördert wird, kommen Leute schnell auf die idee, Sterilisierung wäre ja das Beste für diese Leute. Haben wir teilweise schon wieder, diesen Diskurs, u.a. in der AfD. Irgendwann kommen die Leute auf die Idee, dass töten viel kosteneffizienter und "humanitärer" wäre. Zack, neues Level durchgespielt. Wir sind gerade zwischen Schritt 2 und 3 von vier. Also bei allem Respekt: bisschen den Leuten zuhören, die davon betroffen sind, wenn man sich als Menschenfreund wähnt. Aber vermutlich ist es einfacher, wie die Elterngeneration "nix gewusst" zu haben. Aber keine Sorge. Wir kennen das schon. Nur diesmal dokumentieren wir's halt.

Replying to @secretsloth@mastodon.art
@secretsloth@mastodon.art yeah, there's a lot of strong voices that might be very competent in their field of expertise but have a hard time imagining other people's experiences being different. I've been refocusing my teaching in usable security to a harder psychology ("understanding humans") focus recently since I noticed such tendencies in students as well. They seem to enjoy the new perspectives.

@WPalant@infosec.exchange yeah. The main issue regarding Google's recent actions is that they are doing everything to become a digitally gated community that everyone needs to do basic things. Once you're in, there's no getting out. It's dystopian but it's what they're doing. Google, the everything app.

Replying to @thief_of_fire@infosec.exchange
@thief_of_fire@infosec.exchange @Gargron@mastodon.social rephrased it. Edit here too: this is btw also relevant in security UX. Depending on your target audience, you may enable informative security for technical users (more explanations about what the software is doing) or less for people who find it confusing (invisible security) and just want to use it for specific purposes other than security. Messenger security is very interesting in that regard. You can never build perfect systems for everybody, that's a given. But if you want your thing to work for as many as possible and get used (!), you need to consider majority needs first. Whether you implement minority wishes later is up to many other factors. MySpace was probably great (never used it), but it also had the advantage of being the first big SSN. The growth of Facebook (as much as I hate meta) shows how different concepts can outperform others if they apply radical usability focused on majority users.

Replying to @thief_of_fire@infosec.exchange
@thief_of_fire@infosec.exchange @Gargron@mastodon.social usability is a spectrum in terms of "how hard is it to use", but that is always connected to task completion. Customisation is nice and may be important to some users, but only to a certain technical level. What you're describing is mainly a function of two things: target audience and investment volume. Customisation options require higher investment. If you want a broad audience but want to be cost-efficient, there will be less options to customise.

Replying to @Gargron@mastodon.social
@Gargron@mastodon.social nope. That digital behaviourism stuff is not true. You are/were interested in it and actively pursued it. Contrary to the average Mastodon user's beliefs (apparently), most people are not inherently interested in tech. They use it, but hate having to deal with it. The main driver of adopting tech is utility and usability. This is why vibe coding is so big. You don't have to work for a product (let's set aside quality issues for now). The computing revolution was mainly driven by modern GUIs and OS that made computers easy to use without programming language knowledge. We mistake usability for the enemy because it's often the same companies that made it easy in the first place that are now enshittifying the product because they hit a plateau in terms of usability while being under pressure to grow.
