Over 200 offensive slurs could soon be banned from competitive Scrabble
The North American Scrabble Players Association (NASPA) seems poised to remove hundreds of offensive slurs from tournament-level Scrabble play.
Words that are “used to cause offense on scatological, prurient, profane or other grounds” are not under discussion this time around. NASPA publishes an obfuscated, anagrammed list of which offensive words fall into each category.
Penguin poop creates a buttload of laughing gas
Gobs of guano from king penguins in the sub-Antarctic give rise to comical clouds of nitrous oxide—aka laughing gas—according to a recent study published in the journal Science of the Total Environment.
ZFS versus RAID: Eight Ironwolf disks, two filesystems, one winner
We exhaustively tested ZFS and RAID performance on our Storage Hot Rod server.
Researchers find an animal without mitochondria
Mitochondria, previously found in all animals, is now in all animals but one.
The Fairey Rotodyne, the vertical takeoff and landing airliner time forgot
The phrase “Urban Air Mobility” (UAM) seems like it’s been with us for quite a while, but really it’s only been in widespread use for two or three years. NASA officially recognized UAM in 2017, calling for a market study of remotely piloted or unmanned air passenger and cargo transportation around an urban area. Most people would probably call this the “air taxi” idea—a vision of hundreds of small, unmanned electric multi-copters shuttling two or three passengers from nearby suburbs or city spaces to vertiports at about 100 mph (roughly 161 km/h).
But if things had worked out differently in the late 1950s and early 1960s, we might have a very different understanding of UAM—something more like mass-transit. We might have had a city-center to city-center 55-passenger vertical take-off and landing (VTOL) airliner shuttling between urban heliports at 180 mph (289 km/h).
Actually, we did have that, it’s just few people remember. It was called the Fairey Rotodyne.
I broke Giant’s handheld scanner system by only buying two things
The employee interface verified that my cart contained two (2) items. She scanned both. It verified that those two items were ones I had scanned. And then it told her that she needed to scan five more items to complete the audit, because the audit requires seven items to be scanned.
How the scourge of cheating is changing speedrunning
How do you catch fakes when it’s easier than ever to manipulate video?
That time a monkey flew to the edge of space
So when NASA’s young engineers at Langley Research Center in Virginia began testing their new Mercury capsule in flight, they wanted to see whether the accelerations experienced during the abort of a Mercury flight shortly after launch were survivable. Enter Sam, an eight-pound rhesus monkey.
Boosting the Real Time Performance of Gnome Shell 3.34 in Ubuntu 19.10
As you may have read many times, Gnome 3.34 brings much improved desktop performance. In this article we will describe some of the improvements contributed by Canonical, how the problems were surprising, how they were approached and what other performance work is coming in future.
The thing is in the case of Gnome Shell its biggest performance problems of late were not hot spots at all. They were better characterised as cold spots where it was idle instead of updating the screen smoothly. Such cold spots are only apparent when you look at the real time usage of a program, and in not the CPU or GPU time consumed.
Nice write-up on addressing stuttering and lag.
What it was like to fly the baddest airplane the world has ever known
The X-15 was not the first rocket-powered aircraft, but it is probably the best one ever built and flown. Before the first X-15 took flight in the late 1950s, the fastest speed airplanes had reached was Mach 3. The X-15 doubled that. And, remarkably, it also went on to fly into space more than a dozen times.
Wireless nanowire lasers absorb infrared, emit blue light
So, where will these be used? I’ve no idea at this point, and I don’t really care—I just love the physics. More seriously, it takes a very bright light to turn a laser on like this (think ~1TW/cm2), so the applications will certainly be niche.

Quake II gets free real-time raytracing updates on June 6
Windows and Linux users will be able to download the first three levels of the graphically updated game as shareware starting at 6am Pacific Time on June 6. You can play the remaining levels and multiplayer if you point the installer to a legit copy of the full game on your hard drive. The source code for the Vulkan-based update will be posted on Github as well, though Quake II expansion packs will not be supported without extra effort from the community.
Stealing Downloads from Slack Users
The vulnerability could have allowed a remote attacker to submit a masqueraded link in a slack channel, that “if clicked” by a victim, would silently change the download location setting of the slack client to an attacker owned SMB share. This could have allowed all future downloaded documents by the victim to end up being uploaded to an attacker owned file server until the setting is manually changed back by the victim.
