From my limited understanding, you should get rid of the post since the birds you want don’t actually use it. Also make sure the hole is the right size for the birds you want to nest there. Lastly, you should break up house sparrow nests if it looks like they are building one.
That makes sense. CPUs and GPUs convert most of their energy use into heat. May as well do something slightly useful with that.
No idea what the numbers are now, but last winter, I think my 3080Ti cost ~$2/day to run and generated ~$1/day in crypto.
I ran a very small mining operation at home back in the day and it definitely was all about trying to optimize everything.
Today, I don’t think mining is economically viable without running a data center, but I still mine in the winter and turn my computer into a space heater for my home office. It definitely doesn’t cover the power cost but it does offset a small portion of it.
Not affiliated in any way but Nicehash is what I use now since it (mostly) runs out of the box with minimal configuration.
As a side note, don’t mine on laptops - you won’t get enough heat to keep a room warm and you might end up with something failing from overheating.
As a counterpoint: From the perspective of the Bitcoin network, Bitcoin is not inherently deflationary as long as mining continues to introduce new coins. Mining rewards do drop over time, but new Bitcoin will continue to be generated until the year ~2140.
I think the view of Bitcoin being deflationary now is based on its increasing/volatile value against other currencies which does encourage people to hold with the expectation that they can sell for more in the future. I’d argue that this is price discovery and not deflation. If it remains where it is now, then I agree that it will just be another casino. If the value stabilizes eventually, then it does offer some benefits, especially in countries where the local currency is a less reliable way to hold money.
Disclosure: I do hold some crypto and obviously would prefer it to go up but it won’t change my life. I just think it’s an interesting experiment at the end of the day.
Both sides are constantly probing for weaknesses along the 1,000km-long front. The Ukrainians are making potentially important advances around the ruined city of Bakhmut into the Klishchiivka area, where the Russian occupiers have not had time to build strong defences. For their part, the Russians still have hopes of regaining Ukrainian territory they have annexed but do not control in the Kherson, Donetsk and Luhansk regions. They have found Ukrainian weak points in the north and the east.
Russia is shelling from across the border the north-eastern town of Vovchansk, forcing the evacuation of its remaining residents. On the eastern front the fortunes have been mixed. For months the Ukrainians aimed to capture Russian-held Kreminna, but in the past few weeks they have been driven back from their forward positions in a nearby pine forest. Between Lyman and Kupiansk, Ukraine lost three small villages last week and the little town of Borova is now in Russian sights. If it falls the Russians will have made considerable progress towards the Oskil river. The Ukrainians’ situation in the town of Avdiivka, 10km north of Donetsk, is also reported to be perilous.
Meanwhile, Russia struck Odessa and its ports with missiles for five consecutive days, hitting a cathedral in the city on July 23rd. Ukraine is striking back: on July 28th it appears to have hit the building of the interior ministry in the occupied city of Donetsk. An explosion in the Russian town of Taganrog, 110km from the nearest Ukrainian front line, was attributed by Vasily Golubev, the regional governor, to debris from a Ukrainian missile that was shot down. Another was reported shot down near the city of Azov, even deeper inside Russia. Several Russian Telegram channels reported heavy Ukrainian shelling of Donetsk and neighbouring Makiivka in occupied Ukraine.
For now the front line is a bloody shoving match, with both sides making small advances and retreats. Despite the lack of major successes, Ukrainian morale seems to be holding up. The troops realise that they are in for a long, hard slog, but Western officials familiar with the situation report that they remain highly motivated.
Near the town of Kupiansk, Pavlo was one of four soldiers heaving giant salamis, bottles of cola and other supplies into the back of their car. Although they had been under constant artillery attack, Pavlo said, “we kill more of them because our artillery is more precise.” Friends had already begun using cluster munitions recently supplied by America, he said, but “we don’t know the result yet.”
In Lyman a bushy-bearded commander going by the call sign “Pokémon” said his men were preparing their defences. This was a good thing, he explained: Russian troops will move forward, exposing themselves and allowing the Ukrainians to hit them with artillery and force them back. He seemed undiscouraged by the slow progress. Victory, he said, would come to whichever side was “better in deception operations”. Several Ukrainian missiles streaked overhead towards the Russian positions. “We just want to smash those fuckers!” Pokémon shouted. “Everyone is in a good mood!” ■
“WE CAN’T DRAW big conclusions yet,” said the senior Ukrainian military officer. Although Ukrainian forces had broken through heavily defended Russian lines on July 26th in the southern Zaporizhia sector (see map) and had since made modest advances in two areas, he said, it was too early to claim more than modest success. “It can’t change the big picture for the moment,” he added.
His caution looks justified. The idea that at the first breach the Russian lines would crumble, setting off a wholesale retreat of the kind that happened last September when Ukrainian forces stormed through the Kharkiv region, was never realistic. “It is fifty-fifty,” the officer said. “Sometimes we have successes and sometimes we have had to take our units back.” Having had six or seven months to prepare their lines for the Ukrainian counter-offensive, the Russians have constructed formidable barriers.
Mick Ryan, a retired Australian army general, describes the Russian obstacle design as being “much more complex, and deadly, than anything experienced by any military in nearly 80 years”. Tens of kilometres deep, it is intended to break up or slow down even the most competent combined-arms teams and separate them from their logistical support. What the Ukrainians are trying to do on the southern front—to drive south to the occupied city of Melitopol and the port of Berdiansk, aiming to cut the Russian occupation forces in two and sever Russia’s land bridge with Crimea—is incredibly hard.
Ukrainian forces are facing a lethal combination: millions of mines, FPV drones that transmit live pictures back to their operators, Lancet loitering munitions, the jamming and disabling of Ukrainian drones, long-range rockets and attack helicopters, all knit together by a dense network of sensors and data links. Even when mines are cleared, aircraft or artillery quickly re-seed the fields with scatterable munitions.
Breaking through such well-prepared defences, says Mr Ryan, requires combined-arms operational skills of the highest order. That is something the Ukrainians have not yet demonstrated at scale, says Michael Kofman, a military analyst who visited the front line earlier in July. Moreover, the techniques and the technology for breaching defences have barely evolved in 30 years. Even the best-trained NATO armies enjoying air superiority might struggle to overcome such obstacles. “We need to break this combination,” says the Ukrainian military source.
On the other hand, the Russian manpower behind these lines has clearly been severely stretched by Ukraine’s strategy of attrition. Russian units, says the source, are “becoming smaller…companies that used to be 150 men are now only 20-30 and battalions of 500-600 are now 200 or 250.” If the breaches in the line that the Ukrainians have achieved can be carried farther, the Russians may have difficulty finding reinforcements.
