NASA has removed the camera from the Webb Space Telescope: Here’s why



After years of setbacks and delays, NASA finally launched the James Webb Space Telescope on Christmas 2020, ushering in a new era of space observation. The Observatory is still going through the initial stages of its mission, a process that includes everything from unfolding the heat shield to aligning the mirrors. Only after their completion will the telescope be able to start observing the farthest corners of the Observable Universe. Before that, however, it would be many months. And here the question arises: why didn’t NASA put cameras on the telescope, thanks to which we could admire the entire process of opening the covers and setting up individual modules? The space agency decided to answer this question.

Nasa explains the lack of cameras on the James Webb Space Telescope

James webb without a cameraIn a new Twitter thread, the official NASA account of the space observatory explained why no cameras were placed on the telescope that could record the deployment process over the coming months. While the inclusion of cameras sounds like an obvious thing that will not only entertain people, but also allow better monitoring of the entire process, NASA says there are several good reasons why it was decided to omit these instruments. The biggest reason NASA did not include cameras to take pictures of the telescope during its travels is quite simple: the side of the observatory facing the sun is completely dark, while the side facing the sun is so bright that any images captured would be filled with high contrast and huge bright flares.

As if that were not enough, NASA would also have to power the cameras, which would mean having to run cables to them. Vibration and heat can travel through the cables to the cameras, affecting their image quality. NASA also explains that it would need to develop a special camera that would be able to withstand the extremes of temperature. The James Webb Space Telescope is already an extremely complex project, and the addition of cameras would only make things more difficult.

Budget video cards will become useless. Ryzen 7000 Mobile Processors May Get Ultra-Performing iGPU, 3D V-Cache Boosted



Budget video cards will become useless Ryzen 7000 Mobile Processors

Phoenix generation Ryzen 7000 mobile processors are credited with incredibly powerful iGPUs. But these APUs may turn out to be even more interesting than previously thought.

Budget video cards will become useless.  Ryzen 7000 Mobile Processors May Get Ultra-Performing iGPU, 3D V-Cache Boosted

Recall that these will be processors based on the Zen 4 architecture. The iGPU of the top models will supposedly have 1536 stream processors, which is twice as much as the Ryzen 7 6800U. This alone is enough to take iGPU performance to a whole new level. But lately, rumors have attributed to the new products a graphics core based on the RDNA 3 architecture. In this case, the performance gain will obviously be much more than twofold.

Now, an insider who has accurately described data about AMD video cards and processors many times has said that mobile Ryzen 7000 can also get a 3D V-Cache chip. This is allegedly indicated by information directly from the factory.

However, it is not clear whether this cache will work with the CPU or with the GPU. In the second case, it will be almost the same as Infinity Cache for Radeon RX 6000 video cards. And this will significantly increase the performance of the graphics core. True, it seems that such APUs will only be in the Ryzen 7000HX line.

But, if all these rumors and leaks are true, the same source’s recent claim that the Ryzen 7000’s iGPU could be comparable to the mobile 60W GeForce RTX 3060 doesn’t sound so fantastic anymore.

Another port of Intel. XeSS technology will not appear in Dolmen on May 20



Another port of Intel XeSS technology will not appear in

Only yesterday we learned that Intel XeSS technology will become available in the first game on May 20, as the developers denied this information.

Another port of Intel.  XeSS technology will not appear in Dolmen on May 20

More specifically, they themselves initially stated that their game Dolmen would support XeSS, and would receive that support with the Day 1 patch on May 20th. But now the studio Massive Work Studio, responsible for the game, wrote that Intel XeSS in Dolmen will appear in the summer. Exactly when is not known, but it does not exactly match previous statements.

Considering that Intel itself promises to finally release desktop Arc graphics cards also in the summer, everything fits together. True, the adapters will initially be exclusive to China, and at first they will be available only as part of finished PCs.

Be that as it may, now at least there will be no strange situation when XeSS technology would become available, and Intel video cards with its support would be absent on the market.

Most likely, the developers of Dolmen really planned to release everything on May 20, since Intel originally planned to release video cards before the summer. But then Intel’s plans changed, so Massive Work Studio had to adjust.

Elon Musk knocks down the price? He does not want to complete the deal to buy Twitter without an audit, which is impossible



Elon Musk knocks down the price He does not want

Elon Musk’s purchase of the social network Twitter is getting more and more interesting. The other day, the billionaire said that the number of fake and spam accounts on Twitter can exceed 90% of the number of daily active users, but in general he leans towards 20%.

Elon Musk knocks down the price?  He does not want to complete the deal to buy Twitter without an audit, which is impossible

Musk has already said he wants to audit, so he put the deal on hold for now. However, there appear to be problems with the audit procedure.

Twitter CEO Parag Agrawal wrote that it is unlikely that an external audit could be carried out.

Unfortunately, we do not believe that this particular assessment can be done externally, given the urgent need to use both public and private information (which we cannot share). Outwardly, it is even impossible to know which accounts are counted as daily active.

Agrawal also said that Twitter is actively fighting spam accounts, blocking more than half a million accounts daily. He reiterated that the company has been counting such accounts for many years, and the rate has always been less than 5%.

Musk said that the CEO of Twitter publicly refused to provide evidence of such indicators, which is why the deal cannot move towards completion.

It is not yet clear how this story will end, but it is likely that all this will allow Musk to buy Twitter for significantly less than the original $ 44 billion. Perhaps from the very beginning, Musk had such a tactic, and now he adheres to it.
