You might reasonably ask why terminals are so slow, and the simple answer is that they don’t have to be fast. You can’t render the information any faster than screen size and refresh rate will allow.As the other answers have said, if you print to a terminal, then you’re employing a completely different output mechanism. Those parameters will dominate any calculation of effective running time. This is controlled by the screen size and refresh rate. It’s a completely safe bet that rendering “Hello, World!” this way is not any slower than rendering a smoothly running game.In this setup, the dominating bottleneck is the time it takes to display a frame. A game engine would do a whole lot more to fill up the frame buffer. For fairness, we’ll clear every frame and build it up from scratch. Definitely not forever.To do this we only have to render “Hello, World!” as a 103-by-8 bitmap once and then repeatedly copy that into a frame buffer. On a 1920x1080 display that means 1 hour at 120 Hz as before, 2 hours at 60 Hz, or 4 hours at 30 Hz. Scale that up by the appropriate small integer factors for a smaller display and/or lower frame rate. just under 14 minutes to display “Hello, World!” a billion times. That means it will take about 834 seconds, i.e. Let’s round that up to 10k, for convenience.Assuming a frame rate of 120 Hz, we can display “Hello, World!” about 1.2 million times per second. So we can fit “Hello, World!” 37*270 = 9990 times on a 4K screen. The same 4K screen has a height of 2160 pixels and can therefore hold 270 lines. Assuming an 8x8 bitmap font, let’s say we can fit it 37 times on a line of a 4K screen, which is 3840 pixels wide (in order to do that we’ll shave off one pixel from the blank space). There are diesel generators at the plant, which also has alternative water sources.Let’s do an apples-to-apples comparison.“Hello, World!” is 13 characters long. Grossi has repeatedly called for an end to fighting in the vicinity of the facility to avoid any catastrophic accidents. Russian forces captured both the nuclear plant and the Kakhovka hydroelectric dam shortly after President Vladimir Putin sent them into Ukraine on Feb. Grossi's trip was delayed by a day for security reasons amid heavy fighting. Reaching a written agreement would be unrealistic at this stage because, as we know, there are no peace or ceasefire negotiations between the parties," TASS quoted Grossi as saying. "We have a political agreement which was formulated at the (United Nations) Security Council. He also said that IAEA inspectors would remain at the site. Grossi was earlier quoted by Russian news agencies as saying the situation at the site was "serious" but that the level of cooling water was sufficient. Instead, the pond, which is separated from the reservoir, can be replenished using deep underground wells, they say. The Kakhovka reservoir was normally used to refill the cooling pond adjacent to the plant, but cannot do so now because of its falling water level following the breach, officials say. FIGHTING COMPLICATES SECURITYĮarlier in the day, Grossi said it was unrealistic to expect Moscow and Kyiv to sign a document on the site's security while fighting raged nearby. The station's six reactors are now in shutdown.Īn IAEA spokesman said that gunfire briefly halted Grossi's convoy as it headed back to Ukrainian-held territory following the visit, but the delegation was in no immediate danger.Ī Russian energy industry official was earlier cited by Tass news agency as accusing Ukraine of opening fire at the convoy. Russia and Ukraine have repeatedly accused each other of shelling near the plant, endangering its safe operation. Grossi said the visit, his third to the plant in southern Ukraine since Russian forces occupied it in the first days of their February 2022 invasion, had gathered "a good amount of information for an assessment". The plant is going to be working to replenish the water so that safety functions can continue normally." "With the water that is here the plant can be kept safe for some time. "What is essential for the safety of this plant is that the water that you see behind me stays at that level," Grossi said in two tweets issued from near the station, including next to a pond that supplies water for cooling. Rafael Grossi of the International Atomic Energy Agency (IAEA), was inspecting the state of Europe's largest nuclear plant following last week's breach in the Kakhovka dam downstream on the Dnipro River. atomic energy agency said on Thursday that ensuring water for cooling was a priority of his visit to the Russian-controlled Zaporizhzhia nuclear plant in Ukraine, adding that the station could operate safely for "some time".
