Longtime Slashdot reader schwit1 shares a report from Autoblog: ... the problem is that the federal brightness standards for automotive headlights have not changed for decades. The Federal Motor Vehicle Safety Standard No. 108 hasn't had significant updates since 1986, with an addition allowing Adaptive Driving Beam (ADB) headlights coming only in 2022. The NHTSA last investigated (PDF) the issue of headlamp glare in 2003. The current standards include huge loopholes for auto manufacturers to emit as much light as desired, as long as the manufacturer meets the requirements of the other parts of the regulation.

LEDs can be made to focus light using lasers, and auto manufacturers use this ability to their advantage. The regulatory standard prohibits excessive light in certain areas by referencing old technologies, but manufacturers design the areas in question to be shaded so that the total light output can still be increased greatly overall. Manufacturers want as much light as possible in order to get a high score for the IIHS headlight safety ratings. [...] Although the U.S. finally approved the ADB technology in 2022, manufacturers are wary of implementing it because of conflicting regulations, with a few exceptions, such as Rivian.

To fix this problem, the first step is to update Standard 108 with a cap on the maximum allowable brightness for LED technology. Next, states should begin requiring headlight alignment inspection during vehicle inspections. Finally, NHTSA should enforce a ban against the sale of aftermarket LEDs that exceed the allowed brightness, at least for on-road use. The Soft Lights Foundation has collected over 77,000 signatures calling for federal action to limit headlight brightness. People are frustrated with being temporarily blinded while driving, and it's high time some regulation was put into place. Vehicles have become cleaner and safer through smart regulation; the same just needs to be done with headlights.

The Connectivity Standards Alliance and its members that include Apple, Google, Amazon, Samsung, and other smart home manufacturers, today announced the official launch of the Matter 1.0 smart home accessory standard. MacRumors reports: Companies that have agreed to support Matter now have all of the resources that they need to begin implementing Matter into their platforms, so we could see Apple integrating Matter into HomeKit very soon. In fact, iOS 16.1 is already laying the groundwork for Matter, so Matter could be announced with the launch of the update. With the Matter 1.0 launch, authorized test labs are now available for product certification, tools are available, and the open-source reference design SDK is complete. Alliance members with devices that have already been deployed and with plans to update their products with Matter support can do so as soon as their products are certified. The Connectivity Standards Alliance says that the first release of Matter will support a variety of smart home products such as lighting, HVAC controls, window coverings, safety and security sensors, door locks, media devices, controllers, and bridges. "What started as a mission to unravel the complexities of connectivity has resulted in Matter, a single, global IP-based protocol that will fundamentally change the IoT," said Tobin Richardson, President and CEO of the Connectivity Standards Alliance. "This release is the first step on a journey our community and the industry are taking to make the IoT more simple, secure, and valuable no matter who you are or where you live. With global support from companies large and small, today's Matter 1.0 release is more than a milestone for our organization and our members; it is a celebration of what is possible."

sagecreek writes "If you are in charge of a small network with just a few servers, you may still be doing configuration management primarily by hand. And you may take particular pride in maintaining that 'artisan' role. After all, it's mostly up to you to set up new users and their machines, fix current problems, manage the servers and their software, create databases and their user accounts, and try to keep the network and user configurations as uniform as possible despite running several different brands--and vintages--of hardware and software. However, warns infrastructure consultant John Arundel, '[b]eyond ten or so servers, there simply isn't a choice. You can't manage an infrastructure like this by hand. If you're using a cloud computing architecture, where servers are created and destroyed minute-by-minute in response to changing demand, the artisan approach to server crafting just won't work.' In his new book, Puppet 3 Beginner's Guide, Arundel emphasizes: 'Manual configuration management is tedious and repetitive, it's error-prone, and it doesn't scale well. Puppet is a tool for automating this process.'" Read below for the rest of sagecreek's review.

Michael Ross writes "Of all the open source content management systems used for building websites, Drupal has a reputation for being one of the most flexible and powerful available, but not the easiest for web designers to use. Drupal version 7 has made some strides in alleviating those flaws, but there is still much progress to be made. During the past few years, a number of books have been published that explain how Drupal designers can do custom theming, but they tend to focus on the technical details of the theme layer, and not the practice of web design when using Drupal as a foundation. That rich yet neglected subject area is the focus of a new book, Drupal for Designers: The Context You Need Without the Jargon You Don't." Keep reading to see what Michael has to say about the book.

jm2dev writes "The title is self descriptive, you will learn what a REST architecture is, the concepts behind it, advantages and constraints, and how to implement web services in a RESTful way serving and consuming content using the Java programming language, as command line applications, desktop graphical client, run by an application server or even as standalone applications. Almost everything you need to know to start working with web services in Java the REST way is covered by this book." Read on for the rest of Jose's review.

brothke writes "Securing the Smart Grid: Next Generation Power Grid Security, authors Tony Flick and Justin Morehouse provide a comprehensive and first-rate overview of smart grid technology and what is needed to ensure that it is developed and deployed in a secure and safe manner. An issue is that smart grid has significant amount of hype around it, including the promise that it will make energy more affordable, effective and green. With that, promises around security and privacy are often hard to obtain." Read on for the rest of Ben's review.

Last year's Blizzcon was tremendously popular. So much so that their servers were unable to handle the strain of fans competing for 15,000 available tickets. This year, Blizzard was more prepared; they made an additional 5,000 tickets available and set up a queue so that the transaction servers weren't overwhelmed. CEO Mike Morhaime said during the keynote address that if you weren't able to get into the queue within 30 seconds of its opening, the tickets were sold out before your turn came. Tens of thousands more chose to order the pay-per-view coverage, demonstrating the extraordinary enthusiasm felt for Blizzard's games. Their presentations didn't disappoint.

It's divided into sections by game in case you're only interested in one or two of them.

mantex writes "The title of this book combines two coded terms — 'Web 2.0' and 'The Enterprise' — for which read 'social networking software' and 'Big Business.' And the purpose is to show how the techniques and concepts behind Web 2.0 applications (blogs, wikis, tagging, RSS, and social bookmarking) can be used to encourage collaboration efforts in what was previously thought of as secretive, competitive businesses."

Last week at GDC I had the privilege of sitting down to speak with a representative from CCP, the folks who maintain EVE Online. The week before, we'd asked for questions to pass on. I had the chance to put them directly to Magnus Bergsson, CMO at CCP. He very directly tackles the recent scandal involving a CCP developer, the reason why EVE's hardcore gameplay is so appealing, the balance between casual and hardcore players, and some information on the future of the game. Read on for his answers to your questions in a transcript of the interview, as well as audio live from the GDC Expo floor.

Andrew Stellman writes "Jennifer Greene and I have an article in the new issue of Dr. Dobb's Journal called "Quick-Kill Project Management: How to do smart software development even when facing impossible schedules." We got a lot of great feedback from our last article on open source development, but there were a bunch of people who wanted to know whether it was really feasible to do planning and reviews on a tight schedule. That's a fair question, and this article is meant to be an answer to it. We pulled out bare-bones project management practices that will help you protect your project from the most common and serious problems, and gave instructions and advice for implementing them that should work in a real-life, high-pressure programming situation."

Dustin Puryear writes "I work extensively with LDAP as a consultant, and so I'm always reading the latest and greatest books and articles on the subject. It's just part of the business. So I was excited to see "Deploying OpenLDAP," by Tom Jackiewics and published by Apress, on Amazon's electronic bookshelf. After reviewing the Table of Contents I quickly ordered the book. This looked good. After all, Jackiewicz had some great chapter titles such as 'Implementing Deployment, Operations, and Administration Strategies.' That just sounds smart. Before giving you my feelings on the book, let me first say that I'm already well experienced with LDAP. This is especially true with OpenLDAP. With a title like "Deploying OpenLDAP" I was expecting a book that tackled not just low-level tactical issues such as installing OpenLDAP binaries, but strategic ones as well, e.g., how to design access control. So if you have never used OpenLDAP then your experience with the book may differ." Read on for the rest of Puryear's review.

prostoalex writes "How many times, when playing Dungeons and Dragons by yourself, or reading an RFC in the bed alone on a Friday night, have you thought 'Boy, I sure wish there was an easier way to pick up women, like published API with code samples?' What would you say if such documentation was not only available, but succinctly put into 22 design patterns and given formal descriptions just like the ones in your UML book? Dating Design Patterns, with a cover suspiciously similar to Design Patterns by the Gang of Four, is the first attempt to bring verified solutions to common problems in the world of dating." Timothy's review follows prostoalex's, below.

Sarusa writes "eXtreme Programming has been quite the lucrative phenomenon, with a slew of articles and a bookshelf full of 20+ books on the subject, rivaling even UML for fecundity. With all the hype, where's the opposing viewpoint? Well, it's not often as profitable to write a book on the downside of a hot trend, but Matt Stephens and Doug Rosenberg managed to find a publisher for Extreme Programming Refactored: The Case Against XP by Matt Stephens and Doug Rosenberg, henceforth referred to as XP Refactored because I'm eXtremely Lazy. This book is not intended entirely as a hit piece - as the title indicates, they do spend some time examining what works in XP and how it can be used sanely. (Please note that this book has been reviewed on Slashdot once before, but from a slightly different perspective.)" Read on for the rest of Sarusa's review.

jortega asks: "I am looking into implementing a photo ID system using smart cards, preferably using open-source and cheap components. We currently have several systems for libraries, meal plans, identification using older ID cards, and more, yet none of these systems integrate with each other. I envision a system where a smart card can accommodate all these things in addition to things like print management, purchasing books at the bookstore, meal plans, and security. I have looked extensively on Google and other sites, and while I can find a lot on information on smart cards, I haven't been able to find much on a cheap open-source system that I can build on to accomplish this. Does the Slashdot community have any advice on what to do and where to go from here."

Duane Gran contributes this review of Patterns of Enterprise Application Architecture, writing "The title of this book is a mouthful and the author, Martin Fowler, confronts headfirst complex topics of concern to software developers and architects. Fowler is a respected figure in software engineering circles, and his latest book is an attempt to codify best practices he learned in the trenches and through peer relationships. Many of the patterns will resonate with experienced developers, but Fowler's talent explaining abstract concepts will afford even the most grizzled reader many 'aha!' moments." Read on for the rest of Duane's review.

Rednerd asks: "I've been looking into Smart Cards as a good alternative to password authentication but other than the ISO 7816 standard there doesn't seem to be a lot of standards that govern the use of these devices. It seems pretty clear that if I was working in an all Sun, or Microsoft environment implementing a network wide Smart Card solution would be simple, but there doesn't seem to be a lot of heterogeneous Smart Card support out there. I was wondering what kind of experience slashdot readers have had with Smart Cards in mixed environments? What cards and card readers seem to work the best? How have remote users dealt with the use of Smart Cards?"
