    Noch bis Sonntag steht die interaktive Ausstellung "Stadt in Beton" im Leipzig Nikolaikirchhof: correctiv.org/events/2024/09/1

    In #Leipzig stieg die #Flächenversiegelung zwischen 2018 bis 2024 von 29,2 auf 31,2 Prozent (entspricht 6 km²), wie man der zugehörigen @correctiv_org Auswertung entnehmen kann: correctiv.org/aktuelles/2024/1

    - Station 1 - Auwald: correctiv.org/versiegelungsmon
    - Station 2 - Starkregen: correctiv.org/versiegelungsmon
    - Station 3 - Hitzeinsel Hauptbahnhof: correctiv.org/versiegelungsmon
    - Station 4 - Versiegelung Bürgerbahnhof Plagwitz: correctiv.org/versiegelungsmon
    - Station 5 - Bebauung Jahrtausendfeld: correctiv.org/versiegelungsmon
    - Station 6 - Ohnmacht im Rathaus?: correctiv.org/versiegelungsmon

    Für diese Fakten-schaffende Versiegelung im Leipziger Auwald hätte es eigentlich auch noch eine Station geben müssen: oekoloewe.de/umweltpolitik-nat

    Stattdessen bräuchte es eher solche #Tegelwippen (= #Entsiegelung) Initiativen wie in den Niederlanden: orf.at/stories/3353827/

    Auch wir von Code for Leipzig (codefor.de/leipzig) hatten mal eine Auswertung der Bebauung über die Jahre gemacht: bebauung.codeforleipzig.de

    We have another new feature available for people to use from the AI Horde. This is the capacity to use Layer Diffuse to generate images with a transparent background directly (as opposed to stripping the image background with a post-processor).

    As someone who’s dabbled into video game development in the past (which was in fact the reason I started the AI Horde) being able to generate sprites, icons and other assets can be quite useful, so once I saw this breakthrough, it immediately became something I wanted to support.

    To use this feature, you simply need to flip on the transparent switch if your UI supports it, and the Horde will do the rest. If you’re an integrator, simply send “transparent: true” in your payload.

    Take note that the images generated by this feature will not match the image you get with the same seed when transparency is not used! Don’t expect to take an image you like and remove the background this way. For that you need to use the post-processor approach.

    Also keep in mind, not every prompt will work well for a transparent image generation. Experiment and find what works for you.

    As part of making this update work, me and Tazlin also developed, discovered and fixed a number of other issues and bugs.

    What would be most interesting for you is a slight change on how hires-fix works. I discovered that the implementation we were using was using the same amount of steps for the upscaled denoising which was completely unnecessary and wasting compute. So we now use a smart system which dynamically determines how many steps to use for the hires-fix based on the denoising strength you used for hires-fix and the steps for the main generation, and we also exposed a new key on the API where you can directly pass a hires-fix denoising strength.

    The second fix is allowing hires-fix on SDXL models, so now you can try to generate larger SDXL images at the optimal resolution.

    Finally there were a lot of other minor tweaks and fixes, primarily in the horde-engine. You can read further for more development details on this feature.

    This update required a significant amount of work as it required that we onboard a new comfyUI node. Normally this isn’t difficult, but it turns out this node was automatically downloading its own LoRa models on startup, and those were not handled properly for either storage or memory. Due to the efficiency of the AI Horde worker, we do a lot of model preloading along with some fancy footwork in regards to RAM/VRAM usage.

    So to make the new nodes work as expected, I had to reach in and modify the methods which were downloading models so that they use our internal mechanisms such as the model manager. Sadly the model manager wasn’t aware of strange models like layer diffuse, so it required me adding a new catch-all class of the model manager for all future utility models like these.

    While waiting for Tazlin to be happy with the stability of the code, we discovered another major problem: The face-fixer post-processors we were using until now had started malfunctioning, and generating faces with a weird gray sheen. After some significant troubleshooting and investigation, we discovered that ComfyUI itself on the latest version had switched to a different internal library which didn’t play well with the custom nodes doing the face-fixing.

    First I decided to update the code of the face-fixer nodes we were using, which is harder than it sounds, as it also downloads models automatically on startup, which again needs to be handled properly. Updating the custom nodes fixed the codeformer face-fixer, but gfpgan remained broken and the comfyUI devs mentioned that someone would have to fix it. Unfortunately those nodes didn’t seem to be actively maintained anymore so there was little hope to just wait for a quick fix.

    Fortunately another custom node developer had run into the same problems, and created a bespoke solution for gfpgan licensed liberally, which I could copy. I love FOSS!

    In the meantime, through our usual beta testing process, we discovered that there were still some funkiness in the new hires-fix approach, and Tazlin along with some power users of the community were able to tweak things so that they could work more optimally.

    All in all, quite a bit of effort in the past month for this feature, but now we provide something which along with the embedded QR Code generation, I’ve seen very few other GenAI services provide, if at all.

    Will you use the new transparent image generation? If so, let us know how! And remember if you have a decent GPU, you can help other generate images by adding your PC onto the horde!

    Programming mission: Let’s fix the Fediverse discovery gap

    Here’s a small but powerful challenge for #openweb builders - and a perfect #DIY project if you're fed up with the current #geekproblem. I’ve been trying to find #Fediverse instances that actually cover my town, Oxford, UK, so I can help promote and grow them locally. You’d think this would be simple, right? But… nope. Tried the standard “instance pickers”? Dead ends. Tried generic web searches? Useless #SEO sludge. Tried maps like this one, a good start […]

    Les bonsaïs

    Semis de bonsaï : ce qu’il faut savoir

    Cultiver un bonsaï à partir de graines (appelé “misho” en japonais) est une expérience gratifiante, mais qui demande de la patience et de la rigueur. Voici les points essentiels à connaître pour réussir vos semis de bonsaï.

    Choix et récolte des graines

    • Il n’existe pas de “graines de bonsaï” : ce sont des graines d’arbres ordinaires, que l’on cultive en pot et que l’on forme ensuite en bonsaï[1].

    • Vous pouvez récolter des graines localement (glands, châtaignes, samares d’érable, etc.) ou les acheter dans des magasins spécialisés[1][2].

    • Pour certaines espèces, les graines doivent être débarrassées de leur enveloppe ou pulpe pour éviter les moisissures (ex : pommier, cerisier)[2].

    Période de semis

    • L’automne est la période idéale pour semer, car cela respecte le cycle naturel : les graines passent l’hiver en terre et germent au printemps, profitant ainsi d’un été entier pour se développer[1][7].

    • Si vous semez hors saison ou avec des espèces exotiques, il faudra souvent “stratifier” les graines, c’est-à-dire les placer au froid pour simuler l’hiver[1].

    Préparation et techniques de semis

    • Utilisez un récipient percé pour le drainage, avec une couche de graviers ou de sable au fond, puis un mélange terreux adapté (akadama, pumice, écorce de pin, etc.)[2][5].

    • Semez les graines en les espaçant pour éviter une levée trop dense. Recouvrez-les de terre tamisée : 1 à 2 cm pour les grosses graines, quelques millimètres pour les plus fines[5].

    • Maintenez une humidité constante, sans excès d’eau. Une mini-serre ou un couvercle transparent peut aider à conserver l’humidité et la chaleur[5][6].

    • Température idéale pour la germination : entre 15 et 26°C selon les espèces[5][6].

    Premiers soins et repiquage

    • Les semis restent généralement dans leur pot jusqu’au printemps suivant, moment du premier rempotage[2].

    • Dès qu’ils ont 2 vraies feuilles (pas les cotylédons), vous pouvez repiquer les jeunes plants pour leur donner plus d’espace[2].

    • L’objectif des premières années est de former un bon système racinaire (nebari), essentiel pour la stabilité et l’esthétique du futur bonsaï[4].

    Patience et formation

    • Il faut compter au moins 5 ans pour obtenir un jeune bonsaï à partir d’un semis de feuillu, et jusqu’à 10 ans pour un conifère[2][3].

    • Avant toute taille (racines, branches), attendez que le jeune plant soit bien enraciné et vigoureux, soit 1 à 2 ans après la germination[3].

    • Les premières interventions visent surtout à orienter la croissance des racines et à sélectionner les sujets les plus prometteurs[4].

    Risques et conseils

    • Le principal risque est la fonte des semis (maladies fongiques). Pour limiter ce risque, veillez à une bonne aération, un substrat bien drainé et évitez l’excès d’humidité[2].

    • Ne semez pas trop de graines : chaque plant demande de la place et des soins sur plusieurs années[2].

    En résumé, le semis est la méthode la plus longue mais aussi la plus formatrice pour créer un bonsaï à votre image, depuis la graine jusqu’à l’arbre adulte. Elle nécessite patience, observation et rigueur, mais offre la satisfaction de voir évoluer un arbre que vous aurez accompagné dès ses premiers jours[1][2][3].
