Fewer than 100 Russian troops remain in Kupyansk, Kharkiv region, according to Joint Forces spokesperson Viktor Tregubov. The clearing operation is nearing completion, with remaining Russians mostly hiding in basements in the city’s central and northwestern areas. Despite this, Russian commanders reportedly have orders to retake the city by February.
Katie Miller, wife of White House Deputy Chief of Staff Stephen Miller, posted an image of Greenland colored in the U.S. flag, captioned “Soon.” The provocative post has sparked speculation about renewed American interest in the island, which is part of the Kingdom of Denmark.
“We can secure access to additional wealth and resources, allowing the country to unlock them without spilling American blood,” said U.S. Defense Secretary (Secretary of War) Pete Hegseth, highlighting the strategic and economic rationale behind the Venezuela operation.
According to Axios, the CIA embedded a team of agents in Venezuela as early as August 2025 to prepare for Nicolás Maduro’s capture. They tracked his movements, diet, and routines, and even trained using a full replica of his residence, complete with steel-reinforced doors.
Trump claimed Maduro and his wife tried to flee into a steel-armored safe room but were intercepted just in time.
Cuban President Miguel Díaz-Canel declared strong support for Venezuela, saying, “When it comes to Venezuela, we are ready to give even our own blood. Down with imperalism!,” he said.
President Zelensky stated that the presence of British and French troops in Ukraine is essential as part of future security guarantees. Speaking after the “Coalition of the Willing” meeting, he emphasized that the UK and France play a leading role and their military presence must be part of any long-term framework.
В 2026достигнем гендерного равенства? В Италии — правая министрка. В Японии тоже. Примеры женщин-консерваторок часто используют в спорах о гендерных квотах. Мол, если женщины ничем не гуманнее мужчин, разве квоты что-то меняют?
Так ли эффективна политика, которая способствует увеличению числа женщин в органах власти? И могут ли они сделать политику более инклюзивной и справедливой?

The first footage has emerged of Nicolás Maduro after his arrival in the U.S. According to CNN, both Maduro and his wife have been placed in a detention facility in Brooklyn, New York, ahead of their expected court proceedings.
Russia launched 52 attack drones overnight, including around 40 Shaheds, from multiple directions. Ukrainian air defenses downed or jammed 39 of them over the north and east. Hits were recorded at 9 locations, with drone debris falling in one area.

Wow, I’ve just tried #brow6el - a #sixel based terminal (!) web browser - on one of classic Polish portals, packed with ads and mashup JS/HTML. And it… works!
Sixel is an old (DEC times) but very clever protocol for displaying 6-bit graphics right in terminal window, Brow6el is a Chromium-engine using Sixel graphics to render the pages. So essentially you’ve got a fully functional graphical (!) web browser in a text terminal. Because it’s still Chromium, this particular website uses ~500 MB of RAM.
Surprisingly, the build process on Ubuntu is also rather trivial and takes ~5 min (thanks to the use of prebuilt Chromium binary I suppose)

#Russia military bloggers are concerned about what happens with billions dollars worth of advanced weapons they kindly sold on long-term loans to Maduro. Their biggest concern is “won’t it somehow reappear in #Ukraine with Trump’s silent approval” 😄 One thing he’s certain about - “Caracas won’t pay back any loans, that’s for sure”.
President Volodymyr #Zelenskyy on Saturday commented on the military operation in Venezuela, during which the US captured the country's leader, Nicolás Maduro.
🇺🇸 "Trump’s sharp words on Putin, paired with a dramatic operation against Maduro, are raising fresh questions about Washington’s strategy toward #Russia, Ukraine – and the wider authoritarian axis." 🤔
💬 Any future security guarantees for #Ukraine must include the physical presence of foreign troops on Ukrainian territory, President Volodymyr Zelensky said on Jan. 3, stressing that forces from France and the U.K. are essential for peace.

#CBAM – EU Carbon Border Adjustment Mechanism – is live from 1 January 2026:
This means that those importing more than 50 tonnes of cement, iron and steel, aluminium, fertiliser, as well as all importers of electricity or hydrogen need to have submitted an application or received an authorisation at the time of import. Importers who have not already submitted applications need to act fast now to avoid risking disruptions, delays, or penalties. Applications must be submitted prior to import and at the latest by 31 March 2026 for all concerned import companies.
The purpose of the CBAM is, in short, to end the absurdity of EU setting some CO2 emission cutting goals and then achieving them exclusively by an accounting trick where high-CO2 products are imported from countries that don’t care, as if CO2 emissions respected political borders. It also will make EU production of the same goods more competitive on the internal market which is currently throttled by high energy pric

The most interesting thing about #Venezuela right now is this flood of narratives along the lines of ‘the events of 2026 justify the events of 2014/2022’.
These arguments are noticeable, if not widespread, and it is most interesting that they are mostly coming from people in the US and Europe. Who, in theory, should understand concepts such as logic, chronology and moral universalism.
Instead, they seem to have completely internalised Soviet dialectical thinking, conveniently mainstreaming Russian sophistry.

Russia’s Foreign Ministry on Saturday called for the release of Venezuelan leader Nicolás Maduro and his wife from U.S. custody after President Donald Trump announced that they were captured during military strikes on the capital city of Caracas.
Venezuelan Vice President Delcy Rodriguez is in Russia, four sources familiar with her movements said on Saturday, after President Donald Trump said President Nicolas Maduro had been seized by U.S. forces after an attack on the country.
U.S. President Donald Trump said on Saturday he was frustrated with Russian President Vladimir Putin over the continued war in Ukraine, repeating that he had initially believed that ending the war would be easy.

Russian oligarch Oleg Deripaska is realizing what will happen, when the US get control over Venezuela's oil reserves:
"If our American "partners" get to the oil fields of Venezuela (and they have already reached the fields of Guyana), they will control more than half of the world's oil reserves. And, apparently, their plan is to ensure that the price of our oil does not rise above $50 per barrel."
And Oleg, it is getting even worse for Russia. China might cope somehow, maybe even find common ground with the new government in Venezuela, together with the US, but Russia is absolutely screwed. Venezuela just needs to be unleashed and the oil price will run into the ground, if necessary below $30 per barrel.
Outgoing US Congresswoman Marjorie Taylor Greene does not take Maduro's fall well. She is going ballistic, questioning the motives of the operation while accusing the Trump administration not acting in America's best interests.
"Americans disgust with our own government’s never ending military aggression and support of foreign wars is justified because we are forced to pay for it and both parties, Republicans and Democrats, always keep the Washington military machine funded and going.

Fewer things in bathrooms should have the hands free sensors. If you’re getting soap, you’re literally in the middle of washing your hands, the germs will come off. Most people getting paper towels also probably have clean hands. I’m tired of waving my hands around trying to get these things to work, bring back levers.
@Pam I've seen people handling soap dispensers before putting any water on them, so I think hand-free can be an improvement, but mainly if it becomes a foot pedal. But then you run into different accessibility issues.
FPGA Dev Kit Unofficially Brings MSX Standard Back
In the 1980s there were an incredible number of personal computers of all shapes, sizes, and operating system types, and there was very little interoperability. Unlike today’s Windows-Mac duopoly, this era was much more of a free-for-all but that didn’t mean companies like Microsoft weren’t trying to clean up all of this mess. In 1983 they introduced the MSX standard for computers, hoping to coalesce users around a single design. Eventually it became very successful in Japan and saw some use in a few other places but is now relegated to the dustbin of history, but a new FPGA kit unofficially supports this standard.

The kit is called the OneChip Book and, unlike most FPGA kits, includes essentially everything needed to get it up and running including screen, keyboard, and I/O all in a pre-built laptop case. At its core it’s just that: and FPGA kit. But its original intent was to recreate this old 80s computer standard with modern hardware. The only problem is they never asked for permission, and their plans were quickly quashed. The development kit is still available, though, and [electricadventures] goes through the steps to get this computer set up to emulate this unofficially-supported retro spec. He’s also able to get original MSX cartridges running on it when everything is said and done.
Although MSX is relatively unknown in North America and Western Europe, it remains a fairly popular platform for retro computing enthusiasts in much of the rest of the world. We’ve seen a few similar projects related to this computer standard like this MSX-inspired cyberdeck design, but also others that bring new hardware to this old platform.

This particular examination of this lunar thrust module is a good example of how a system’s complexity can quickly get out of hand. Rather than one pin there are two pins to indicate auto or manual thrust, each working with different voltage levels; the manual thrust is as given but the auto thrust is only the part of the thrust that gets added to a baseline thrust, so they need to be handled differently, requiring extra logic and wiring for biasing the thrust meter when appropriate. The video goes into further detail. Toward the end of the video [Mike] shows us what the meter’s backlights look like when powered.

He starts off with a very relatable observation: have you ever noticed that when you plug in a pickle, only half of it lights up? What’s up with that? Well, it’s related to the asymmetry he sees on his Jacobs ladder that has one side grow hotter than the other. In fact, it goes back to something welders who use DC know about well: the Debye sheath.
The arc of a welder, or a Jacobs ladder, or a pickle lamp is a plasma: ions and free electrons. Whichever electrode has negative is going to repel the plasma’s electrons, resulting in a sheath of positive charge around it. This positively-charged ions in the Debye sheath are going to accelerate into the anode, and voila! Heating. That’s why it matters which way the current goes when you’re welding.
With DC, that makes sense. In AC, well — one side starts as negatively charged, and that’s all it takes. It heats preferentially by creating a temporary Debye sheath. The hotter electrode is going to preferentially give off electrons compared to its colder twin — which amplifies the effect every time it swings back to negative. It seems like there’s no way to get a pure AC waveform across a plasma; there’s a positive feedback loop at whatever electrode starts negative that wants to introduce a DC bias. That’s most dramatically demonstrated with a pickle: it lights up on the preferentially heated side, showing the DC bias. Technically, that makes the infamous electric pickle a diode. We suspect the same thing would happen in a hot dog, which gives us the idea for the tastiest bridge rectifier. Nobody tell OSHA.
[The Action Lab] explains in more detail in his video, and demonstrates with ring-shaped electrode how geometry can introduce its own bias. For those of us who spend most of our time slinging solder in low-voltage DC applications, this sort of thing is fascinating. It might be old hat to others here; if the science of a plain Jacobs ladder no longer excites you, maybe you’d find it more electrifying built into a blade.

These sensors, one of which is marked as ‘backup’, are read out by multiple ADCs connected to a couple of FPGAs. The system further has an ARINC 429 transceiver, for communicating with the other avionics components. Naturally the multiple PCBs are conformally coated and with vibration-proof interconnects.
Although it may seem like a lot of hardware just to measure air pressure with, this kind of hardware is meant to work without errors over the span of years, meaning significant amounts of redundancy and error checking has to be built-in. Tragic accidents such as Helios Airways Flight 522 involving a 737-300 highlight the importance of these systems. Although in that case human error had disabled the cabin pressurization, it shows just how hard it can be to detect hypoxia before it is too late.

[Codeolences] tells us about the FORBIDDEN Soviet Computer That Defied Binary Logic. The Setun, the world’s first ternary computer, was developed at Moscow State University in 1958. Its troubled and short-lived history is covered in the video. The machine itself uses “trits” (ternary digits) instead of “bits” (binary digits).
When your digits have three discrete values there are a multiplicity of ways of assigning meaning to each state, and the Setun uses a system known as balanced ternary where each digit can be either -1, 0, or 1 and otherwise uses a place-value system in the normal way.
An interesting factoid that comes up in the video is that base-3 (also known as radix-3) is the maximally efficient way to represent numbers because three is the closest integer to the natural growth constant, the base of the natural logarithm, e, which is approximately 2.718 ≈ 3.

Printing in Metal with DIY SLM
An accessible 3D printer for metals has been the holy grail of amateur printer builders since at least the beginning of the RepRap project, but as tends to be the case with holy grails, it’s proven stubbornly elusive. If you have the resources to build it, though, it’s possible to replicate the professional approach with a selective laser melting (SLM) printer, such as the one [Travis Mitchell] built (this is a playlist of nine videos, but if you want to see the final results, the last video is embedded below).
Most of the playlist shows the process of physically constructing the machine, with only the last two videos getting into testing. The heart of the printer is a 500 Watt fiber laser and a galvo scan head, which account for most of the cost of the final machine. The print chamber has to be purged of oxygen with shielding gas, so [Travis] minimized the volume to reduce the amount of argon needed. The scan head therefore isn’t located in the chamber, but shines down into it through a window in the chamber’s roof. A set of repurposed industrial servo motors raises and lowers the two pistons which form the build plate and powder dispenser, and another servo drives the recoater blade which smooths on another layer of metal powder after each layer.
As with any 3D printer, getting good first-layer adhesion proved troublesome, since too much power caused the powder to melt and clump together, and too little could result in incomplete fusion. Making sure the laser was in focus improved things significantly, though heat management and consequent warping remained a challenge. The recoater blade was originally made out of printed plastic, with a silicone cord along the edge. Scraping along hot fused metal in the early tests damaged it, so [Travis] replaced it with a stainless steel blade, which gave much more consistent performance. The final results looked extremely promising, though [Travis] notes that there is still room for redesign and improvement.
"President Trump's repeated claim, in prepared remarks, that the United States would now 'run Venezuela' 'until a safe, proper, and judicious transition' can take place was hopefully untrue. The American people did not sign up for a nation-building campaign in Venezuela. They haven't even been asked. The Secretary of War's claim that the attack was about 'the safety, security, freedom, and prosperity of the American people' strains credulity past the breaking point. "
Ooh, post back with how you get on with it. I love how it looks, and I like narrative games, but after the first few cutscenes I just thought everybody was so pretentious I couldn’t cope with it any more.
Vor der Weltpresse in Florida deutete Trump an, dass sich die USA im Rahmen ihrer regionalen Strategie als nächstes mit Kuba beschäftigen könnten. "Ich denke, wir könnten auch über Kuba reden, denn Kuba ist ein gescheiterter Staat", sagte er. Außenminister Marco Rubio äußerte sich deutlicher: "Wenn ich die kubanische Regierung in Havanna wäre, wäre ich besorgt."
Und der Kanzler steht daneben und kneift die Arschbacken zusammen.
Ich habe immer noch einen Twitter Account und schaue dort bei Zeiten rein. (ohne etwas zu posten, denn es lohnt sich nicht mehr) Einer meiner dortigen Kontakte, der leider derbe abgedriftet ist, hat einen Post geteilt, der wie folgt anfängt:
And OF COURSE the EU is once again sucking the d*ck of the Dictator
Und ich dachte: "Oh, er ist Trump-kritisch geworden." Aber dann ging es weiter damit, dass wir die USA nicht kritisieren, sondern ihr danken sollten. Der im Zitat gemeinte Diktator war Maduro.
@Michael 🇺🇦 Ja, das ist tragisch. Vor allem, wenn man die Person anders kennengelernt hat. Wer Twitter weiterhin nutzt, hat dafür einen bestimmten Grund, und der ist vermutlich kein Guter. Menschen können verloren gehen. Das muss man akzeptieren.
Tra il 1979 e il 1983, Roma scopre un nuovo terrore. Non sono le BR, non è la Magliana. È una banda guidata da un uomo in divisa che entra nelle ville dei quartieri alti per restarci.
She jumped up onto the table once while we were playing, stomped across all the dice in the middle, singled out one in particular, and batted it with her paw - natural 20, obviously
Buonasera a tutti! Nel 2023 ho creato per curiosità il mio account mastodon, non avevo ben capito che dovevo scegliere il server, mi son ritrovato su mastodon.social, la desolazione degli italiani, vedevo persone che emigravano su mastodon.uno, andavo nelle impostazioni però sembrava complicato, avevo paura di sminchiare (termine tecnico) tutto e quindi ho resistito fino ad oggi. Finalmente mi son deciso, anno nuovo server nuovo!!! 🤣🤗🤭🇮🇹
@GeorgeSfiladini ciao, come ti hanno già detto mastodon.social è un po' una desolazione per gli italiano, pochi account e la timeline locale troppo intasata, per spostarti c'è una guida, questa: mastodon.it/it/migrazione-acco…
Fermo da metà ottobre 2025 a causa di un incidente che mi ha causato una frattura biossea esposta alla gamba sinistra.Per la prima volta nella mia vita avevo raggiunto e superato la soglia dei 6000 km in un anno, sarebbe stata la mia ultima uscita con le ruote da strada e avevo già pronte ruote con copertoncini da ciclocross per tornare a fare un po' di strade bianche e sentieri. E invece...
Quasi un mese di fissatore prima che finalmente mi operassero per l'osteosintesi con chiodo e placca.
Non si è al sicuro nemmeno sulle ciclabili. Questo è il primo danno visibile alla bici, ovviamente cerchio da cambiare. Da verificare forcella e telaio. Da qualche giorno ho ripreso a pedalare (piano e per pochi minuti) sulla cyclette. Tra una settimana nuova RX e visita di controllo.
La cosa scandalosa è che nonostante la presunta "eccellenza" della sanità lombarda, per poter fare fisioterapia col SSN avere la priorità "Urgente - entro 10 gg" non serva a nulla, si parla di almeno 4-5 mesi di attesa pure nella stessa s

Ovviamente in regime di solvenza il posto salta fuori.
I don’t, but then people being blocked without reports is very rare and typically happens when we are responding to active “attacks”, like spam or (more recently) propaganda campaigns
I, and probably people like me, block and don't report in most cases. Sometimes someone is just an arsehole, and can't be reported for anything specific. And I try not to report people just because I don't like them 😇
I understand. We don’t block everyone that gets reported. There is a lot of attempts to “weaponize moderation” when there are petty disagreements. I do wish more people would just block each other. Obviously, report stuff that is inappropriate for the platform, though. So thank you.
I definitely do not and will not mine/analyze what accounts/instances people are blocking. That seems rather antithetical to the point of this place.
Grazie a @DavidPuente per la verifica delle informazioni sulle notizie relative all'attacco USA al Venezuela. Un lavoro efficace ed equilibrato (malgrado le sue posizioni dichiaratamente ostili al corrotto e autoritario regime di Maduro)
@elCelio il profilo mastodon di @DavidPuente è molto poco attivo (però ogni tanto si risveglia 😅) ma intendevo soprattutto segnalare la pagina di Open con gli aggiornamenti sul Venezuela più che il suo profilo
inevitabile che circolino fake su una notizia del genere, ma non leggo una chiara condanna su quanto accaduto. Il diritto internazionale è morto, ormai vale solo la legge del più forte, la Russia si spingerà più ad ovest, la Cina annetterà Taiwan
💬 "We now have a new wave, a new chance to end this war. And we are grateful that we are not alone on the diplomatic path. I would like to thank our partner countries and their leaders for their consistent support for our country."

Президент США Дональд Трамп, министр обороны Пит Хэгсет, госсекретарь Марко Рубио и председатель Объединенного комитета начальников штабов США генерал Дэн Кейн провели совместную конференцию, посвященную военной операции США в Венесуэле и захвату президента страны Николаса Мадуро. Непосредственно перед этим президент США опубликовал в своей соцсети Truth Social фотографию арестованного Мадуро. По его словам, фото было сделано на борту американского судна, которое доставило Мадуро к берегам...
Non trovo niente da aggiungere a quello che scrive in modo ragionato ma con tanta amarezza Paolo Attivissimo. La domanda con cui si conclude l'articolo "Adesso cosa facciamo?" è rivolta anche a noi.
La BBC di stamattina. Quando ho scritto a fine 2024 che il risultato elettorale americano dimostrava che l’umanità è troppo cretina per meritarsi qualunque attenzione da parte di eventuali civiltà …
potremmo iniziare con il chiederci cosa avremmo potuto fare per non arrivare in questa situazione, perché tutto questo non è caduto dal cielo all'improvviso come una pioggia estiva. Forse aiuterebbe a maturare consapevolezza di dove siamo, come ci siamo arrivati ed eventualmente iniziare a fare qualcosa per cambiare direzione.
invece di partire dalla retrospettiva, partirei con una raccolta di proposte di attività pratiche e processi *valutati con un occhio alla retrospettiva*
vedo due assolute priorità 1) assicurarsi i mezzi tecnici e le competenze per comunicare in modo sicuro (confidenzialità, non censurabilità innanzitutto, ma in alcuni casi anche ripudiabilità plausibile) 2) assicurarsi i mezzi e le conoscenze per fronteggiare la limitazione delle libertà di associazione, di movimento, e di espressione
Negli ultimi anni, l’immaginario collettivo della cybersecurity ha fin troppo spesso romanticizzato l’hacker solitario, genio ribelle in grado di violare

cosa facciamo? Di certo non qualcosa di risolutivo in tempi brevi. Ma sicuramente bisognerà lavorare molto sull'istruzione dei ragazzi e delle classi meno abbienti
#Hungary – citing “national security,” Orbán’s government denied public information request by journalist Szabolcs Panyi’s for agreements signed with Maduro in #Venezuela (including oil & gas) 2 years ago.
Today’s mentions of FM Péter Szijjártó’s meeting with #Maduro are nowhere to be found on the #Hungary government website. Seems like Maduro bet on a wrong horse…
Meanwhile Orbán commented on today’s USA attack on #Venezuela:
“It’s not clear who attacked whom,” Hungarian PM Viktor Orbán said today at a presser.
Oh wait, no - he said that about #Russia vs #Ukraine in December, my mistake 😂
The first crematorium at Auschwitz I was already in operation since August of 1940, and the first gas chamber since the fall of 1941. The number of planned c...
🇺🇦 President Volodymyr Zelensky suggested to appoint Denys Shmyhal, the country's defense minister and ex-prime minister, to lead #Ukraine's Energy Ministry.
The move follows a major political reshuffle, with a number of high-ranking officials being reassigned to different government jobs.
Ma... mi chiedevo: augurare a Trump prurito al culo e braccia corte, è di destra o di sinistra? 🤔 Così, giusto per inquadrarmi nello scacchiere politico.
Perché facciamo un concorso della foto dell’anno? Non per assegnare premi ma per celebrare la bellezza, le #cosebelle, e ricordarci perché condividiamo immagini.
ci è sembrato giusto usare Pixelfed per fare l’esatto opposto dei social: mostrare il bello, fermarsi un attimo, guardare.
popolo dei non-televisivi italieni, vi siete ricordati di fare la dichiarazione annuale di non possesso di apparecchio atto a ricevere il segnale tv onde evitare che vi addebitino il canone sulla bolletta della luce?
it’s basically a chemical reaction that involves a quantity of gold and proximity to whatever is in that bronzer that results in either presidential pardons or removed regulations.
There are simple mechanisms: Trump insults you? You did something right. FIFA awards you a price? You got accepted in the knighthood of the Corruption Brothers. German banks close your account? You're on the right path. ...
We found out that the actual Nobel Peace Prize winner is not respected but the FIFA peace prize winner is the most respected. Thank you for your attention to this matter.
I certainly hope the EU can put the same sanctions on the US for attacking Venezuela as they did on Russia for attacking Ukraine. This is indefensible.
@Gargron Actually, the US’s 1953 intervention in Iran helped install the Shah, which backfired into the 1979 revolution and the current regime. Venezuela was a targeted strike to remove Maduro after years of failed sanctions and his narco-regime’s threats. Different eras, different contexts. If regime change via precision ops works there, why not with Iran’s ayatollahs sponsoring terror? Or are we just supposed to ignore their nuclear ambitions and proxy wars forever? Not warmongering—realism.
Dopo 10 ore, sono arrivate le prime parole della Presidente del Consiglio Giorgia Meloni sull’attacco di Trump in Venezuela.
Ed è una supercazzola senza precedenti, un centrifugato di servilismo e cerchiobottismo in cui Meloni riesce a dire tutto e il contrario di tutto.
"Coerentemente con la storica posizione dell’Italia, il governo reputa che l’azione militare esterna non sia la strada da percorrere per mettere fine ai regimi totalitari” scrive Meloni.
Quindi uno pensa: ohibò, sta condannando Trump. Incredibile. Inaudito. Forza che questa volta ce la fa!
Ma lei spariglia di coda e prosegue, contraddicendosi nel giro di tre righe.
“Ma - prosegue Meloni - considera al contempo legittimo un intervento di natura difensiva contro attacchi ibridi alla propria sicurezza, come nel caso di entità statuali che alimentano e favoriscono il narcotraffico".
Legittimo??
Cosa????
Quali interventi difensivi?
Per difendersi da cosa?
Quali “attacchi ibridi”?

E poi quel riferimento al narcotraffico, come se qualcuno sano di mente potesse davvero credere alla lotta di Trump ai narcotrafficanti.
Questo non è un comunicato.
È il diritto internazionale fai da te.
È la resa finale dell’Italia di Giorgia Meloni all’America di Trump, l’ammissione scritta che non contiamo nulla, non serviamo a nulla e non toccheremo palla per i prossimi dieci anni.
Il punto forse più basso mai toccato da un Presidente del Consiglio in politica estera nella storia recente.
quindi con la stessa motivazione l'Italia potrebbe violare la Patria dei francesi, visto l'elevato e documentato traffico di droga transfrontaliero? 🤔 Quindi il concetto di Patria vale solo "a targhe alterne" quando fa comodo alla Propaganda di Regime? Personalmente, continuerò a considerare l'intera specie umana come mia Patria, senza per questo discriminare gli altri esseri viventi. Ah, già ma io non difendo nessuna lobby! Perbacco!

Ultimamente ho un brutto rapporto con i social. Non mi sento a mio agio. Non riesco più a gestire lo spazio di condivisione come vorrei e mi incastro nelle contraddizioni politiche di piattaforme gestite da aziende i cui principi sono anni luce distanti dai miei. Non credo esistano luoghi sicuri e non credo esistano mondi senza contraddizioni, ma mi fa piacere accettare l'invito di @kenobit su questo profilo, creato nel 2024 per un live proprio con lui.
#Venezuela hat die größten #Erdölreserven der Welt. Für eine US-Regierung, die weiterhin auf fossile Energieträger setzt, ist es folgerichtig, den Zugriff auf solche Ressourcen #militärisch abzusichern. Europa besitzt selbst kaum noch eigene Erdölvorräte. Um nicht zum Spielball künftiger Verteilungskämpfe um Erdöl zu werden, sollte Europa möglichst schnell unabhängig von Erdöl werden. Erneuerbare Energien, eine schnelle #Energiewende und das Verbrenner-Aus sichern damit auch unseren #Frieden.
