So the question is: are #photo #communities still a thing? I remember beautiful group #chats where we discussed about a lot of things. Would it make sense to start one today? As simple as possible, just a place to talk freely.

“[The author has] already discussed ancient water management systems, such as the qanats in Persia and other Eastern countries. In Europe, there are the acequias of the Sierra Nevada in Andalusia, Spain.
The hand-dug channels date back over 1,000 years to the Moorish era. Networks of canals, aqueducts and cisterns were engineered to capture and transport snowmelt, turning this natural resource into a sustainable water supply for agriculture. The high-altitude ditches had openings, allowing water to infiltrate into fractures and faults, replenishing the aquifer, and to irrigate the lower levels of the slopes.
𝗪𝗵𝗮𝘁 𝗱𝗲𝗳𝗶𝗻𝗲 𝗮𝗰𝗲𝗾𝘂𝗶𝗮𝘀?
✅ Gravity-fed irrigation that supported terraced farms and local biodiversity.
✅ Designed to distribute water slowly and equitably, even during dry summers.
✅ Stretching over thousands of kilometres, these systems fell into disuse in the 1980s but are now part of restoration efforts led by the MEMOLA Project (Universidad de Granada).
With climate change and more intense droughts, the Acequias could provide an ancient solution to the modern-day water crisis…”

the #ArcaneChat channels list now also has #Russian channels
the list is rather short, if you know someone with a channel in Russian that would like to add it to the list, tell them to contact me
-
@costalfy actually we added more channels!
we updated https://arcanechat.me/channels to support listing channels in different languages and added some more French channels!

Зоопарк каналов в Rust: какой выбрать и как не споткнуться
Каналы - механизм передачи данных между потоками или асинхронными задачами. Идея простая: один конец отправляет сообщения (отправитель), другой их получает (получатель), а вся синхронизация спрятана внутри. За этим стоит целый подход: вместо того чтобы разделять память и вручную её блокировать, данные передают сообщением. На практике же стоит копнуть глубже, и оказывается, что каналов в экосистеме Rust целый зоопарк: std::sync::mpsc , crossbeam-channel , tokio::sync , flume , async-channel , kanal и ещё несколько менее известных. Они отличаются моделью, поддержкой асинхронности, скоростью и кучей мелких деталей, о которые легко споткнуться. В этой статье разберёмся, какие каналы бывают, чем они отличаются и какой брать под конкретную задачу.

Communicating without internet – first steps (#Meshcore)
TL;DR I've set-up a #meshcore repeater and bought 2 companion devices to communicate (chat) with people without relying on the internet. My setup works, kinda, but damn, that's a whole new level of rabbit hole. Am I prepping? You never know when your country catches a dictatorship which turns off the internetz (like in Iran). Or, when countries decide to install backdoors to chat apps like Signal. Naah, I'm not paranoid, just like to tinker with unknown (to me) stuff. This is a write-up […]https://blog.rozman.info/communicating-without-internet-first-steps-meshcore/

Just polled my software team: without googling or asking, have you heard of #copyfail ? if so, do you know what it is sufficiently to explain it to a colleague?
Not a single hand. We make embedded #linux devices. ( yes, ours are affected.)
Call me old fashioned, but when I was a #developer I _kept tabs on shit_. First coffee every morning was pouring over #slashdot and #thedailywtf and a dozen tech specific #blogs and #newsgroups and #channels. Whats new, or blowing up?

#Messages 🗣️ Many #companies communicate too many topics, which dilutes core messages and prevents target groups from understanding.
#TargetGroups 🎯 Instead of #analysing real needs, decisions are often made based on gut feeling, resulting in campaigns that completely miss the mark.
#Channels 📲 There is discussion about whether TikTok or LinkedIn is »right« without first defining #content and #strategy, which is fragmented and ineffective.

Beyond Hormuz: Busy and risky global shipping channels
Once again, the Strait of Hormuz has become the unfortunate ground zero for the world’s power brokers. But, it’s definitely not the only major shipping channel that has geopolitical risks associated with it. Of the busiest global shipping channels, at least four are currently experiencing instability, not to mention the usual risks from weather, pirates (yes pirates), and navigational dangers.
Source: theconversation.comThe Kerch Strait (see map below in the list) between Russia and Ukraine has been impacted by the ongoing war between those two nations and the Taiwan Strait is affected by tensions between China and Taiwan. The Bab el-Mandeb Strait (see map below in the list) between the Horn of Africa and the Arabian Peninsula has been the scene of attacks on shipping, as well.
Ukraine attacked two Russian vessels transporting weapons and military equipment through the Kerch Strait on March 14, 2026. (Ukraine’s military intelligence agency / Telegram) – Source: kyivindepedent.comWhile the Strait of Hormuz is vital to oil and natural gas, it pales on in comparison to other global shipping channels listed below for the total number of ships/year passing through it. This maybe due to the immense size of oil tankers compared to other ships, but it is also located a bit off-the-beaten-path from the main shipping routes plus the Strait of Hormuz has only one real outlet. Furthermore, two pipelines have redirected a portion of the crude oil away from the Strait of Hormuz (see map just below) to other shipping points.
Source: eia.govFortunately, most of world’s busiest shipping channels are presently peaceful. But the risks associated with them does point to their strategic and tactical importance. And while they are now quiet, they haven’t always been so. Unfortunately, with increased importance comes added risk(s) or at least the potential for upheaval.
Unlike other resources that combine all Danish and St. Lawrence shipping channels into one number, this blogpost breaks these two routes down into their subparts to provide a more detailed picture. Given that there are multiple shipping channel options through the Danish Straits alone, it did not seem accurate to combine them all into one category. Similarly, at 1,900 miles, the sheer length of the St. Lawrence Seaway system was out of character with these other major passages.
The busiest global shipping channels (whether currently peaceful or risky) are provided below. As always, any additions, corrections, or suggestions to the list below are most welcome.
Peace!
