Lone modder’s Half-Life 2: Update brings modern graphics to a classic

As amazing as Half-Life 2 was when it was first released in 2004, time has not been kind to the original release’s graphics, which can look a bit flat and dated compared to modern PC games. Enter Romanian modder Filip Victor , who’s ready to release the final version of a massive, Source engine-powered graphical update for the game on Steam for free tomorrow. As shown in a slick comparison trailer and detailed in a PDF brochure , Half-Life 2: Update offers graphical improvements like high dynamic range lighting, improved fog and particle effects, world reflections, more detailed water rendering, improved background models, and other effects that just weren’t feasible back in 2004. The update also fixes a number of animation and cut-scene-activation bugs that have persisted in the original release and adds optional fan commentary from a number of high-profile YouTube personalities. Despite all the graphical changes, the update leaves the original gameplay, level design, character models, textures, and animations intact. “The goal of Half-Life 2: Update is to fix up, polish, and visually enhance Half-Life 2 , without ever changing the 2004 original’s core gameplay, or time-tested style,” Victor wrote in the update’s brochure. “I wanted to ensure that the update was something that would be enduring, and worth the time it takes to play it. I hope that both newcomers and veterans of the Half-Life series will enjoy seeing the work that went into its creation.” Read 2 remaining paragraphs | Comments

Graphene allows strange form of ice to occur at room temperature

We are all familiar with water, and we see it every day in many forms: in the bulk as a glass of water, in the crystal phase as ice, and the vapor phase as steam. While the behavior of these phases seems predictable, water is an unusual substance that behaves unlike any other small molecule we know of. This fact is particularly notable when water is viewed at small-length scales or confined to small compartments. An international team of scientists recently discovered some intriguing structural characteristics of water confined in graphene nanocapillaries. In these studies, the researchers deposited a graphene monolayer on a small grid, added a small amount of water, and then covered it with another monolayer of graphene. This sample was left overnight to allow excess water to evaporate, eventually bringing the graphene layers together so that only a small amount of adsorbed water remained between them. The water left behind showed some unusual structural properties. Structural characteristics of water are influenced by hydrogen bonding among adjacent water molecules. In the liquid state, water exhibits a partially ordered structure. In the crystal state, water molecules begin to conform to more rigid lattice structures, forming ice. As ice, the water molecules typically take on a geometry that is a three-dimensional “tetrahedral” structure, which basically looks like a square pyramid. Read 4 remaining paragraphs | Comments

New WoW item will allow players to trade gold for game time

Blizzard will soon allow World of Warcraft players to trade purchased game time for in-game gold, and vice versa, effectively putting an official, floating real-world value on the in-game currency. With yesterday’s rollout of WoW patch 6.12, Blizzard says it’s ready to introduce the ” WoW token,” a new in-game item that can be traded for 30 days of play time in the subscription-based MMO. Blizzard says the new feature will be launched in the Americas “once Patch 6.1.2 has been live for a while [to] help us ensure the foundation for the feature is solid.” Other regions will get tokens further down the line. WoW tokens will be available for purchase from the in-game shop for $20 or “the rough equivalent” in other regions. That’s somewhat more than the $14.99 maximum usually charged for a single month’s subscription fee, but the tokens differ from regular subscription game time because they can be exchanged for in-game gold through an in-game auction house.

Big solar plants produced 5% of California’s electricity last year

Today, the US Energy Information Agency announced that California had passed a key milestone, becoming the first state to produce five percent of its annual electricity using utility-scale solar power. This represents more than a doubling from the 2013 level, when 1.9 percent of the state’s power came from utility-scale solar, and means that California produces more electricity from this approach than all of the remaining states combined. The growth in California was largely fueled by the opening of two 550MW capacity photovoltaic plants, along with two large solar-thermal plants. In total, the state added nearly two GigaWatts of capacity last year alone. The growth is driven in part by a renewable energy standard that will see the state generate 33 percent of its electricity from non-hydro renewables by 2020; it was at 22 percent in 2014. Other states with renewable standards—Nevada, Arizona, New Jersey, and North Carolina—rounded out the top five. Both Nevada and Arizona obtained 2.8 percent of their electricity from solar; all other states were at one percent or less. Read 2 remaining paragraphs | Comments

Google warns of unauthorized TLS certificates trusted by almost all OSes

In the latest security lapse involving the Internet’s widely used encryption system, Google said unauthorized digital certificates have been issued for several of its domains and warned misissued credentials may be impersonating other unnamed sites as well. The bogus transport layer security certificates are trusted by all major operating systems and browsers, although a fall-back mechanism known as public key pinning prevented the Chrome and Firefox browsers from accepting those that vouched for the authenticity of Google properties, Google security engineer Adam Langley wrote in a blog post published Monday . The certificates were issued by Egypt-based MCS Holdings , an intermediate certificate authority that operates under the China Internet Network Information Center (CNNIC). The Chinese domain registrar and certificate authority, in turn, is included in root stores for virtually all OSes and browsers. The issuance of the unauthorized certificates represents a major breach of rules established by certificate authorities and browser makers. Under no conditions are CAs allowed to issue certificates for domains other than those legitimately held by the customer requesting the credential. In early 2012, critics blasted US-based CA Trustwave for doing much the same thing and Langley noted an example of a France-based CA that has also run afoul of the policy.

All four major browsers take a stomping at Pwn2Own hacking competition

The annual Pwn2Own hacking competition wrapped up its 2015 event in Vancouver with another banner year, paying $442,000 for 21 critical bugs in all four major browsers, as well as Windows, Adobe Flash, and Adobe Reader. The crowning achievement came Thursday as contestant Jung Hoon Lee, aka lokihardt, demonstrated an exploit that felled both the stable and beta versions of Chrome, the Google-developed browser that’s famously hard to compromise . His hack started with a buffer overflow race condition in Chrome. To allow that attack to break past anti-exploit mechanisms such as the sandbox and address space layout randomization, it also targeted an information leak and a race condition in two Windows kernel drivers, an impressive feat that allowed the exploit to achieve full System access. “With all of this, lokihardt managed to get the single biggest payout of the competition, not to mention the single biggest payout in Pwn2Own history: $75,000 USD for the Chrome bug, an extra $25,000 for the privilege escalation to SYSTEM, and another $10,000 from Google for hitting the beta version for a grand total of $110,000,” Pwn2Own organizers wrote in a blog post published Thursday . “To put it another way, lokihardt earned roughly $916 a second for his two-minute demonstration.” Read 2 remaining paragraphs | Comments

Classic FPS Descent to be rebooted by Star Citizen alums

The last time we checked in with Eric “Wingman” Peterson was August of 2014, where he was running Cloud Imperium Games’ Austin office and overseeing development on Star Citizen’s persistent universe. However, just a few months after that, Peterson left Cloud Imperium to develop his own game: a reboot of the mid-’90s first-person shooter game Descent. Peterson has formed Descendent Studios , hired a development staff, and is currently overseeing a Kickstarter to pull together a minimum of $600,000 to finance development of the game, which is titled Descent Underground . Critically, Descent Underground has something that previous attempts to resurrect the Descent franchise have lacked: a licensing agreement with IP-holder Interplay. Kickstarter teaser for Descent Underground , formerly code-named “Ships That Fight Underground.” Old name, new presentation Descent was published by Interplay more than 20 years ago, in 1994. The first-person shooter developed by Parallax Software had players zipping around underground in a series of cavernous (and sometimes claustrophobic) mines filled with mad killer robots. Players navigated the underground environment in a Pyro GX spacecraft, which led to the game’s main selling point: it wasn’t just a regular FPS, but one which offered “six degrees of freedom.” In other words, you could move in any direction (X, Y, and Z) and turn in any direction (roll, pitch, yaw).

A $6 commute with Wi-Fi, USB ports, and coconut water

SAN FRANCISCO—In a city replete with not only local buses, and the famously-hated tech company buses that shuttle hundreds of workers daily 40 miles south, a new startup is set to debut a private luxury commuter bus line, charging $6 for a roughly three-mile ride. At its Wednesday launch, Leap will only operate four buses (with one more in reserve) during commuting hours, focusing on giving rides from the Marina neighborhood in the city’s north, going southeast to downtown in the morning, and the reverse in the evening. There’s no fixed schedule—the buses are just constantly rolling at 10 to 15 minute intervals, and passengers can check the iOS or Web apps to see when they will arrive. (Ars first profiled Leap in March 2014.) Leap is betting that riders are willing to pay nearly three times what a ride on a local Muni bus costs, and a fair bit less than what a taxi (or its newer cousins, Uber, Lyft, and Sidecar) would charge for a similar journey. What makes it worth that price? Free Wi-Fi, comfortable seats (limited to just 27, no standing passengers), USB ports, plus food and drinks. Read 24 remaining paragraphs | Comments

Consumer SSDs benchmarked to death—and last far longer than rated

We last checked in with TechReport’s grand SSD torture test back in June , when the first drives in the six-drive roundup had failed. The drives to first fall victim to the unending barrage of data writes were the Intel 335, one of two Kingston HyperX 3Ks (the one tasked with an non-compressible workload to stymie its compression-happy Sandforce controller), and the Samsung 840. All three failed short of 1PB of writes, but it’s also important to note that all of them—even the TLC-equipped Samsung 840—far exceeded their manufacturers’ stated write lifetimes. But now the experiment has come to its grand conclusion : all the drives have finally gone silent, their controllers unresponsive, their NAND cells heavy with extra electrons . The TechReport’s post-mortem is glorious in its depth and detail, with tons of data points and charts describing the course of the experiment and the fate of each of the drives. Tech-savvy buyers who might be worried about SSD lifetime decreasing even as SSD capacity skyrockets should have their fears assuaged by the ridiculous number of writes the tested drives endured; the drive that survived the longest survived more than 2.4 petabytes worth of sustained writes. That’s probably about 240x as much writing as a typical consumer SSD would need to endure over its lifetime. Read 2 remaining paragraphs | Comments

Indian ISP’s routing hiccup briefly takes Google down worldwide

For a short time today, people all over the world trying to access Google services were cut off because of what Dyn Research Director of Internet Analysis Doug Madory identified as a “routing leak ” from an Indian broadband Internet provider. The leak is similar to a 2012 incident caused by an Indonesian ISP , which took Google offline for 30 minutes worldwide. Routing leaks occur when a network provider broadcasts all or part of its internal routing table to one or more peered networks via the Border Gateway Protocol, causing network traffic to be routed incorrectly. In this case, the Indian ISP Hathway’s boundary router incorrectly announced routing data for over 300 network prefixes belonging to Google to the Internet backbone via its provider Bharti Airtel. “Bharti in turn announced these routes to the rest of the world,” Madory wrote in a Dyn Research blog entry posted this morning, “and a number of ISPs accepted these routes.” In the US, Cogent and Level 3 accepted the routes; a number of overseas carriers, including Orange, were also affected.
