[...] Complaints about Silicon Valley insularity are as old as the Valley itself. Jim Clark, the co-founder of Netscape, famously decamped for Florida during the first dot-com era, complaining about high taxes and expensive real estate. Steve Case, the founder of AOL, has pledged to invest mostly in start-ups outside the Bay Area, saying that "we've probably hit peak Silicon Valley." But even among those who enjoy living in the Bay Area, and can afford to do so comfortably, there's a feeling that success has gone to the tech industry's head. "Some of the engineers in the Valley have the biggest egos known to humankind," Mr. Khanna, the Silicon Valley congressman, said during a round-table discussion with officials in Youngstown.
Are neural networks just hyper-vigilant, finding sheep everywhere? No, as it turns out. They only see sheep where they expect to see them. They can find sheep easily in fields and mountainsides, but as soon as sheep start showing up in weird places, it becomes obvious how much the algorithms rely on guessing and probabilities. Bring sheep indoors, and they're labeled as cats. Pick up a sheep (or a goat) in your arms, and they're labeled as dogs.
The Frankfurt simulation is the more basic network, based on 100 MHz of 3.5GHz spectrum with an underlying gigabit-LTE network on 5 LTE spectrum bands, but the results are still staggering. Browsing jumped from 56 Mbps for the median 4G user to more than 490 Mbps for the median 5G user, with roughly seven times faster response rates for browsing. Download speeds also improved dramatically, with over 90 percent of users seeing at least 100 Mbps download speeds on 5G, versus 8 Mbps on LTE.
Yet there is a way that messages from space might be disruptive. Extraterrestrials could simply give us some advanced knowledge -- not as a trade, but as a gift. How could that possibly be a downer? Imagine: You're a physicist who has dedicated your career to understanding the fundamental structure of matter. You have a stack of reprints, a decent position, and a modicum of admiration from the three other specialists who have read your papers. Suddenly, aliens weigh in with knowledge that's a thousand years ahead of yours. So much for your job and your sense of purpose. If humanity is deprived of the opportunity to learn things on its own, much of its impetus for novelty might evaporate. In a society where invention and discovery are written out of the script, progress and improvement would suffer.
The confusion -- and rumored performance hits -- are causing some sysadmins to adopt a "watch carefully" and "wait and see" approach... "The problem is that the patches don't come at no cost in terms of performance. In fact, some patches have warnings about the potential side effects," says Sandra, who recently retired from 30 years of sysadmin work. "Projections of how badly performance will be affected range from 'You won't notice it' to 'significantly impacted.'" Plus, IT staff have to look into whether the patches themselves could break something. They're looking for vulnerabilities and running tests to evaluate how patched systems might break down or be open to other problems.
The article concludes that "everyone knows that Spectre and Meltdown patches are just Band-Aids," with some now looking at buying new servers. One university systems engineer says "I would be curious to see what the new performance figures for Intel vs. AMD (vs. ARM?) turn out to be."
Last night, Snapchat posted an official response to the petition, reiterating its stance but also promising a few tweaks that may help to address users' concerns. Specifically, the company said that "beginning soon on iOS and with Android in the coming weeks" it will introduce tabs in the Friends section and in Discover, which it says will make it easier for users to find the Stories they want. This update will let users sort things like Stories, Group Chats, and Subscriptions. Whether these tabs will placate users who just want the old Snapchat back remains to be seen.
