Rockets and space travel are both fascinating topics, but few people really hold a firm understanding of just how rockets work or how space travel is possible. course ($12.99) provides a considerable amount of information on both topics crammed into a short 2.5-hour program. Although this series of lectures is quite interesting, it’s a hard course to recommend. Overview The first lecture in this course sets a solid foundation for the rest of the course to build on. It defines a rocket as any type of motorized device that contains both its own mass to expel (i.e. fuel) and its own oxidant (i.e.

SpaceX launched its first full batch of Starlink internet satellites in May aboard a Falcon 9 rocket. These spacecraft will eventually become part of a massive swarm that beams broadband data down to the masses, but the reliability of SpaceX’s hardware isn’t perfect just yet. The company reports that . Losing three satellites in a matter of weeks doesn’t sound great, and indeed, it would be preferable if none of them failed. However, SpaceX CEO Elon Musk used a classic “underpromise and overdeliver” maneuver prior to launch. He noted that the Starlink satellites are using a lot of new technology, and it was possible none of them would work.
If you intend to upgrade the RAM on any of your computers and said machines are powered by DDR4, it’s time to bite the bullet and do the upgrade. While we can’t literally guarantee that RAM prices won’t continue to decline, they’ve fallen far enough to qualify as an automatically excellent value, especially if you scrimped on RAM 18 months ago to avoid paying what were then very high prices. We’ve been watching RAM prices for roughly 17 months now, and have seen them decline from $180 for 16GB of DDR4-3200 to just $56 today. That’s a drop of nearly 70 percent, and it’s one reason we’re comfortable giving a blanket recommendation to anyone on the upgrade fence.
You might be the type to dig around in the Windows settings to make tweaks, but that’s just the tip of the iceberg. The Windows registry contains a plethora of low-level settings that control various aspects of the OS. Microsoft used to perform regular backups of the registry, but that has now officially . If you want to save the registry, you’ll have to manually re-enable the feature. Last October, Windows 10 stopped backing up the registry automatically, although the system reported the backups had completed. Navigating to the RegBack folder showed files that were 0 Kb in size.
For most businesses, a brief power outage wouldn’t cause more than a momentary hiccup, or a longer-than-average coffee break. Western Digital and Toshiba, however, are dealing with a problem of vastly larger proportions, and NAND production at both companies will take a serious hit this quarter as a result. The 13-minute power outage affected wafers that had been processed, the facilities, and the actual production equipment. Apparently, the result will result in overall production for the quarter being reduced by 6EB, or exabytes. (There are 1000TB in a petabyte, and 1000PB in an exabyte). Put simply, the loss of 6EB represents a great deal of dead or unproduced NAND.
It’s been a while since we’ve visited the high-end of the graphics market, but it’s a good time to do so. Nvidia’s Turing has had a little more time to bake than the last time we checked in on these cards and AMD’s own Radeon VII has been in-market for quite some time as well. Gigabyte’s Aorus GeForce RTX 2080 Xtreme 8G is a mouthful to say. At $879, it’s also significantly more expensive than even most of the standard RTX 2080 GPUs, which start around $700. In order to justify hitting this kind of premium, Gigabyte will need to bring an impressive product to market, over and above what Nvidia has offered with the RTX family.

There are numerous ways to identify people and just as many ways to foil that identification. The Pentagon has reportedly developed a new way to ID individuals that works from a distance and is harder to evade than other methods. The “Jetson” system to measure a person’s heartbeat, which is apparently almost as distinctive as other indicators. Development of Jetson started after US Special Forces asked for a new way to identify targets from a distance. Tools like gait analysis and facial recognition have been valuable, but there are ways to evade them. For example, gait analysis doesn’t work if someone is standing still or seated, and it’s easy to block facial recognition with a mask or hilarious novelty fake mustache.
