The 1st Corps Azov of Ukraineโs National Guard has confirmed that Rodynske remains under Ukrainian control, despite Russian propaganda claims. As of January 4, the 14th and 20th Operational Brigades, along with the 132nd Recon Battalion, continue to hold positions.
A Venezuelan man asked about the situation: โI ask everyone to have faith and not be misled by claims that the Americans only want our oil and wealth. To those saying that, I ask, what did the Russians and Chinese want all this time? The recipe for arepas?โ
President Zelensky issued a clear and urgent appeal to Ukraineโs international partners, stressing that continued and reliable support is not just a matter of politics, but a matter of survival.
โOver 1,070 guided bombs, nearly 1,000 attack drones, and six missiles launched by Russia in just the past week. He underscored that missiles for air defense systems, currently sitting in warehouses abroad, could be actively saving lives if deployed to Ukraine now.

While you're right about #Trump making invasions "acceptable," #China ๐จ๐ณ has been testing its ability (i.e., "planning") to take #Taiwan ๐ณ๐ซ for decades, and it hasn't come close to succeeding, so I'm not so sure if #Venezuela ๐ป๐ช changes anything in that regard. ๐ค
@TimMaddog Yes, certainly! I agree that it doesn't make a purely military difference, however, it sets a bad precedent for quick military actions because it didn't attract enough scrutiny ๐
@TimMaddog Also, I'm not sure the military operational level is what has held China back so far. Political and economical factors might be the bigger constraints.
Nothing has ever "held #China ๐จ๐ณ back" but their own inability. #Russia ๐ท๐บ made weak-ass excuses to invade #Ukraine ๐บ๐ฆ three years ago, but #Taiwan ๐ณ๐ซ remains untouched.

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.

FPGA Dev Kit Unofficially Brings MSX Standard Back

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 itโs 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. Heโs 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. Weโve 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 systemโs 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 meterโs backlights look like when powered.

Pickle Diodes, Asymmetric Jacobs Ladders, and Other AC Surprises
While weโre 100 years past Edisonโs fear, uncertainty, and doubt campaign, the fact of the matter is that DC is a bit easier to wrap oneโs head around. Itโs just so honest in its directness. AC, though? It can be a little shifty, and that results in some unexpected behaviors, as seen in this video from [The Action Lab].
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? Whatโs up with that? Well, itโs 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 plasmaโs 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. Thatโs why it matters which way the current goes when youโre welding.
With DC, that makes sense. In AC, well โ one side starts as negatively charged, and thatโs 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 โ which amplifies the effect every time it swings back to negative. It seems like thereโs no way to get a pure AC waveform across a plasma; thereโs a positive feedback loop at whatever electrode starts negative that wants to introduce a DC bias. Thatโs 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 youโd find it more electrifying built into a blade.

These sensors, one of which is marked as โbackupโ, 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.

Its troubled and short-lived history is covered in the video. The machine itself uses โtritsโ (ternary digits) instead of โbitsโ (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 โ 3.

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 isnโt located in the chamber, but shines down into it through a window in the chamberโs 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 couldnโt cope with it any more.
Vor der Weltpresse in Florida deutete Trump an, dass sich die USA im Rahmen ihrer regionalen Strategie als nรคchstes mit Kuba beschรคftigen kรถnnten. "Ich denke, wir kรถnnten auch รผber Kuba reden, denn Kuba ist ein gescheiterter Staat", sagte er. Auรenminister Marco Rubio รคuรerte sich deutlicher: "Wenn ich die kubanische Regierung in Havanna wรคre, wรคre 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 anfรคngt:
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 ๐บ๐ฆ Ja, das ist tragisch. Vor allem, wenn man die Person anders kennengelernt hat. Wer Twitter weiterhin nutzt, hat dafรผr einen bestimmten Grund, und der ist vermutlich kein Guter. Menschen kรถnnen verloren gehen. Das muss man akzeptieren.

Buonasera a tutti! Nel 2023 ho creato per curiositร 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 perรฒ sembrava complicato, avevo paura di sminchiare (termine tecnico) tutto e quindi ho resistito fino ad oggi. Finalmente mi son deciso, anno nuovo server nuovo!!! ๐คฃ๐ค๐คญ๐ฎ๐น

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

I donโt, but then people being blocked without reports is very rare and typically happens when we are responding to active โattacksโ, 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 ๐
I understand. We donโt block everyone that gets reported. There is a lot of attempts to โweaponize moderationโ 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 รจ molto poco attivo (perรฒ ogni tanto si risveglia ๐ ) ma intendevo soprattutto segnalare la pagina di Open con gli aggiornamenti sul Venezuela piรน 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 รจ morto, ormai vale solo la legge del piรน forte, la Russia si spingerร piรน ad ovest, la Cina annetterร Taiwan

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?" รจ rivolta anche a noi.

potremmo iniziare con il chiederci cosa avremmo potuto fare per non arrivare in questa situazione, perchรฉ tutto questo non รจ 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 attivitร pratiche e processi *valutati con un occhio alla retrospettiva*

#Hungary โ citing โnational security,โ Orbรกnโs government denied public information request by journalist Szabolcs Panyiโs for agreements signed with Maduro in #Venezuela (including oil & gas) 2 years ago.

Meanwhile Orbรกn commented on todayโs USA attack on #Venezuela:
