Ex-YouTube engineer reveals how video site worked to kill off Internet Explorer 6

The year is 2009. YouTube, four years old, has become the Web’s leading video site. Though Internet Explorer 6 was far from current—it had been superseded by versions 7 and 8—it nonetheless made up some 18 percent of YouTube’s traffic. These were, after all, the dark days of Windows XP; corporations had overwhelmingly stuck with Windows XP in spite of the release of Windows Vista, and Windows 7 was still some months from release. Many organizations still running XP appeared to be wishing for a kind of computational stasis: they wanted to be able to run Windows XP and Internet Explorer 6 forever, unchanging, which would greatly simplify their maintenance and support costs.

But Internet Explorer 6 was nearly eight years old and seriously showing its age. On its release, the browser had a legitimate claim to be the best, fastest, most standards compliant, and most stable mainstream browser around. But those days were long gone. Compared to the alternatives—Firefox 3.5, Internet Explorer 8, and Google’s Chrome—it was slow, unstable, and riddled with proprietary, non-standard behaviors. This was causing the team developing YouTube considerable pain, with weeks of extra work each development cycle to ensure that the site still worked correctly in the old browser.

According to former YouTube developer Chris Zacharias, this pain prompted the YouTube team to take renegade action to drive users away from Internet Explorer 6 and onto something newer and better. Though YouTube has been under Google’s ownership for about three years, YouTube’s engineers were suspicious and wary of being integrated into Google’s corporate machine. They had their own special set of permissions named “OldTuber,” and anyone with OldTuber permissions could freely modify the YouTube site without going through Google’s usual change management process of code reviews, testing, adherence to coding standards, and so on. It was cowboy territory, where developers could do as they liked. Only the risk of breaking things—and hence losing OldTuber permissions, if not their job—kept them on the straight and narrow.

Pitchford promises no “free-to-play junk” for Borderlands 3

Yesterday’s rollout of the first public gameplay footage for Borderlands 3 went about how you’d expect, with all the requisite guns, explosions, and colorful characters that have been standard for the series from the jump. But some confusingly worded comments about the game’s post-launch monetization have required a bit of clarification from Gearbox CEO Randy Pitchford and others in the company.

During yesterday’s streamed presentation, Pitchford announced that “we’re gonna do some kickass campaign DLC, and I’m sure we’re going to do all kinds of fun customizations like heads and skins. But we’re not doing any of that free-to-play junk. There’s not going to be any microtransactions, there’s not going to be any of that nonsense.”

That specific wording led Game Informer to tweet out an article clarifying that the cosmetic items Pitchford mentioned (i.e. “fun customizations like heads and skins”) are indeed being sold via microtransactions (i.e. small payments). That means Pitchford’s statement that “there’s not going to be any microtransactions” isn’t technically accurate.

Google will soon let users automatically delete location history and other private data in rolling intervals of either three months or 18 months.

“Choose a time limit for how long you want your activity data to be saved—3- or 18-months—and any data older than that will be automatically deleted from your account on an ongoing basis,” Google announced yesterday. “These controls are coming first to Location History and Web & App Activity and will roll out in the coming weeks.”

Google location history saves locations reported from mobile devices that are logged into your Google account, while saved Web and app activity includes “searches and other things you do on Google products and services, like Maps; your location, language, IP address, referrer, and whether you use a browser or an app; Ads you click, or things you buy on an advertiser’s site; [and] Information on your device like recent apps or contact names you searched for.”

Spot the not-Fed: A day at AvengerCon, the Army’s answer to hacker conferences

Participants in AvengerCon III, held at the McGill Training Center at Fort Meade, Maryland, on November 27 take part in a lock pick village put on by TOOOL (The Open Organisation of Lockpickers).

FORT MEADE, Maryland—Late last year, I was invited to a relatively new hacker event in Maryland. Chris Eagle, a well-known researcher in the field of malware analysis and author of The IDA Pro Book, keynoted it. There were a number of really good talks at all levels of expertise, a couple of “Capture the Flag” (CTF) hacking challenges, and all the other typical hallmarks of a well-run hacker conference.

But this event, AvengerCon III, proved to be distinct in a number of ways from the BSides conferences and other events I’ve attended. The first difference was that keynote: Eagle, a senior lecturer at the Navy Postgraduate School, shared some news about an upcoming release of an open reverse engineering tool by referring to its “unclassified cover name.” (The tool was Ghidra, a public reverse-engineering tool developed by the National Security Agency.) There were also a lot more people in camouflage than at most hacker events, and my CTF teammates were military intelligence agents. Perhaps the biggest giveaway that this wasn’t any old hacker event? AvengerCon III was being held on Fort Meade and hosted by the US Army’s 781st Military Intelligence Battalion (Cyber).

Part of the 780th Military Intelligence Brigade, the 781st was once known as the Army Network Warfare Battalion. It was the first Army unit formed to create a “cyberspace operations capability” within the Army—conducting offensive and defensive operations and intelligence collection in support of US forces around the world. So technically, AvengerCon is not a conference. It’s a “training event,” in Army parlance, intended to bring the hacker learning culture to the Army’s cyber warriors.

With cash dwindling, Tesla seeks to raise $2 billion in debt and equity

Elon Musk holds court in a leather bomber jacket.

For the last year, Elon Musk has insisted that Tesla can reach sustained profitability without raising additional cash from investors. But the company is now tacitly admitting that it was wrong, filing papers to raise another $2 billion by selling a mix of debt and equity.

Tesla is seeking to raise money just a few days after reporting an unexpectedly large loss in the first quarter of 2019. That release showed Tesla with dwindling cash in the bank—from $3.7 billion at the start of the year to $2.2 billion on March 31.

The lower cash balance primarily reflected one-time events—paying off a $920 million loan and having a bunch of cars in transit to customers at the end of the quarter. Still, having only $2.2 billion in the bank is a precarious situation for a company that has been known to lose more than $700 million in a single quarter.

Dealmaster: Get Fitbit’s best smartwatch, the original Versa, for just $180

Greetings, Arsians! The Dealmaster returns with another batch of deals and savings to share. Topping our list today is a deal on Fitbit’s Versa smartwatch—now you can get Fitbit’s best smartwatch for just $179.95, which is $20 off its original price of $200.

We’re excited to see this deal on the original Versa because it makes it a better option when compared to Fitbit’s Versa Lite. The company debuted the pared-down smartwatch earlier this year—at $159, the Versa Lite was designed to be a more affordable alternative to the $200 Versa. While it’s a decent smartwatch for its price, it demands quite a few sacrifices. The Versa Lite doesn’t have an altimeter, which tracks floors climbed, it doesn’t have onboard storage for music, it cannot track swim laps, and it cannot show on-screen workouts from Fitbit Coach.

However, the original Versa has all of those features and does everything you’d expect a Fitbit smartwatch to do. It tracks all-day activity, workouts, and sleep, it has a built-in heart rate monitor and connected GPS capabilities, it can automatically track activities with Fitbit’s SmartTrack technology, and it can run apps and show multiple watch faces using Fitbit OS. It also has a battery life of at least four days, so you can leave it on all day long and while you sleep for nearly one week before charging up again.

Dragon was destroyed just before the firing of its SuperDraco thrusters

A rocket prepares for a nighttime launch.

During a news conference Thursday in advance of a SpaceX supply mission to the International Space Station, the company’s vice president of mission assurance, Hans Koenigsmann, provided some additional details about a failure with the company’s Crew Dragon spacecraft 12 days ago.

In the company’s most expansive comments to date, Koenigsmann said the “anomaly” occurred during a series of tests with the spacecraft, approximately one-half second before the firing of the SuperDraco thrusters. At that point, he said, “There was an anomaly and the vehicle was destroyed.”

During the activation phase, the SuperDraco thruster system is pressurized, and valves are opened and closed. Since the accident there has been speculation that there may have been some issue with the composite overwrap pressure vessels, or COPVs, which store rocket fuels at extremely high pressures. The COPVs on Crew Dragon are different from those on the Falcon 9, and they would not have been overly stressed at that moment, Koenigsmann said. “I’m fairly confident that the COPVs are going to be fine,” he said.

LIGO may have spotted a black hole-neutron star merger

Image of two long arms of the LIGO detector in the desert of eastern Washington.

On April 1, the teams behind the three gravitational wave detectors started them up for a new observational run, the first with all three operating in parallel for the full run. With the benefit of three detectors and some upgrades that were done during the downtime, we’re seeing a flood of new data. In just one month, LIGO/VIRGO has seen five gravitational wave events. Three of those are from merging black holes, one was the second neutron star merger, and another may have been the first instance of a neutron star-black hole merger.

A new season

The two LIGO detectors have been a work in progress for years, starting with an early version that everyone acknowledged was unlikely to pick up gravitational waves. But each iteration has allowed scientists to understand the sources of error in their detectors, and they’ve been taken down for regular upgrades. The international collaboration also benefits from the fact that two additional detectors, Europe’s VIRGO and Japan’s KAGRA, have similar designs, and all the teams share what they’re learning about the hardware.

VIRGO joined LIGO for roughly a month in 2017 before its second observational run came to a close. According to Caltech’s Jess McIver, a LIGO team member, work in the intervening time went into “pushing down the quantum noise limits in the detectors.” As a result of the lowered noise, McIver said that the detectors can pick up gravitational wave events farther out into space than was ever possible before. Having three detectors helps provide better spatial information as to where the event actually originated, necessary for doing follow-up observations with traditional observatories. And, as one of the events described today makes clear, three detectors let us continue to take data even if one detector is down temporarily.
