Valve developers discuss why Half Life 2: Episode 3 was abandoned

Source: Ars Technica

Article note: That's pretty consistent with the rumors. On the dev side, Valve went to episodes to have more manageable, less ambitious releases, then got too ambitious to do them. The technical points here match up pretty well with Marc Laidlaw's Epistle 3 plot summary. Then there was an element of developer fatigue + shiny new (multiplayer, profitable) things to put it off with and... we get a cliffhanger. Still one of the most frustrating abrupt endings in all of media.

After Ars spent Half-Life 2's 20th anniversary week looking back at the game's history and impact, Valve marked the occasion with a meaty two-hour YouTube documentary featuring insider memories from the team behind the game itself. Near the end of that documentary, longtime Valve watchers also get a chance to see footage of the long-promised but never-delivered Half-Life 2: Episode 3 and hear more about what led the project to be abandoned.

The Episode 3 footage included in the documentary focuses heavily on a new ice gun that would have served as the episode's main new feature. Players would have been able to use that gun to freeze enemies, set up ice walls as makeshift cover, or construct icy ledges to make their way down sheer cliff faces. The developers also describe a so-called "Silver Surfer mode" that would have let players extrude a line of ice in their path then slide along it at slippery speeds.

The Episode 3 developers were also working on a new, blob-like enemy that could absorb other blobs to grow or split into segments to get around small barriers or pass through grates.

POSSE: Publish (on your) Own Site, Syndicate Elsewhere

Source: Hacker News

Article note: Remember the microformats rel="me" stuff for doing _exactly this_ automatically, that had enough traction for Google to base Buzz on it (before, like all their social network projects, they killed it). We had this, it was good, people were too dumb, and more importantly the coercive, monetizing silos didn't like it.

Two early Unreal games are now permanently free via the Internet Archive

Source: Engadget

Article note: Neat. Unreal is good but distinctly of-its-time (If you want to feel historical progression, there's a real clear Marathon-Unreal then Half Life and Halo split out sequence). UT99 is ...just timelessly fucking fabulous, I play some every now and then because it the pinnacle Arena Shooter. Always preferred it to Quake, feels better than the sequels, etc.

The Internet Archive is one of the very best things on the web, so it's great that the repository is up and running again after recent DDoS attacks. It hosts more than old versions of web pages, though. It hosts a trove of video (I'm forever thankful to whoever uploaded the wonderful Lucha Underground in its entirety), software, text, audio recordings and games as well. There have been two notable additions on the latter front in the form of Unreal and Unreal Tournament, seemingly with the blessing of Epic Games.

You can now freely download disc images of the arena shooters from the Internet Archive via direct links for Unreal and Unreal Tournament. Alternatively, as Game Developer points out, the site OldUnreal offers installers for Unreal and UT, both of which pull the disc images from the Internet Archive and include the latest community-created patches.

The installers are Windows-only for now, but the OldUnreal team is working on Linux and macOS versions. You'll also need to put in a little extra effort to get online with the games and savor their true multiplayer flavors. Heck, you might still even be able to join an Unreal clan.

Epic delisted the Unreal games from Steam and shut down their servers quite some time ago, so this is a nice boost for game preservation. It comes on the heels of GOG introducing a new label for older titles that the platform is maintaining for current hardware. Unreal was one of the first PC games I played as a kid, so it's neat to learn that it will be available in perpetuity through the Internet Archive.

The EdTech Revolution Has Failed

Source: Hacker News

Article note: Broadly, agreed. Much of it is because a swath of the edtech industry are carpetbaggers telling impossible lies ("You can scale individual attention by a factor of 10 if you just use our tool! Decimate your teachers and buy this!") to steal public funding. I appreciate the distinction between "adding computers to everything" being a bad idea and "Teaching computer skills" being a separate concern; we really do need to teach (responsible) computer use, the "Digital Natives" thing failed horribly, the devices and their vendors are in charge, and that's a big problem. I also appreciate that they were nuanced about places where tech use does go well; _if_ you can get students to engage in content on their own time in the form of videos or the like (which, due to students being acculturated to it, works better now than in the past), that's more time learning that is more self-paced than almost anything else we can do, and that's a win. It tends to have fairly superficial engagement, but priming operations like "Hey, I'm going to ask you to use X next week, and I've prepared a tutorial video on X to prepare" often works well.

Criminals Exploiting FBI Emergency Data Requests

Source: Schneier on Security

Article note: As ever, a backdoor for anyone is a backdoor for everyone.

I’ve been writing about the problem with lawful-access backdoors in encryption for decades now: that as soon as you create a mechanism for law enforcement to bypass encryption, the bad guys will use it too.

Turns out the same thing is true for non-technical backdoors:

The advisory said that the cybercriminals were successful in masquerading as law enforcement by using compromised police accounts to send emails to companies requesting user data. In some cases, the requests cited false threats, like claims of human trafficking and, in one case, that an individual would “suffer greatly or die” unless the company in question returns the requested information.

The FBI said the compromised access to law enforcement accounts allowed the hackers to generate legitimate-looking subpoenas that resulted in companies turning over usernames, emails, phone numbers, and other private information about their users.
