An anonymous reader quotes a report from Reuters: The U.S. Environmental Protection Agency proposed a rule on Tuesday that would limit the kinds of scientific research it can use in crafting regulations, an apparent concession to big business that has long requested such restrictions. Under the new proposals, the EPA will no longer be able to rely on scientific research that is underpinned by confidential medical and industry data. The measure was billed by EPA Administrator Scott Pruitt as a way to boost transparency for the benefit of the industries his agency regulates. But scientists and former EPA officials worry it will hamstring the agency's ability to protect public health by putting key data off limits. The EPA has for decades relied on scientific research that is rooted in confidential medical and industry data as a basis for its air, water and chemicals rules. While it publishes enormous amounts of research and data to the public, the confidential material is held back. Business interests have argued the practice is tantamount to writing laws behind closed doors and unfairly prevents them from vetting the research underpinning the EPA's often costly regulatory requirements. They argue that if the data cannot be published, the rules should not be adopted. But ex-EPA officials say the practice is vital.

The Economist reports of a new working paper by the Organization for Economic Co-operation and Development (OECD) that assesses the automatability of each task within a given job, based on a survey of skills in 2015. "Overall, the study finds that 14% of jobs across 32 countries are highly vulnerable, defined as having at least a 70% chance of automation," reports Economist. "A further 32% were slightly less imperiled, with a probability between 50% and 70%. At current employment rates, that puts 210 million jobs at risk across the 32 countries in the study." From the report: The pain will not be shared evenly. The study finds large variation across countries: jobs in Slovakia are twice as vulnerable as those in Norway. In general, workers in rich countries appear less at risk than those in middle-income ones. But wide gaps exist even between countries of similar wealth. Differences in organizational structure and industry mix both play a role, but the former matters more. In South Korea, for example, 30% of jobs are in manufacturing, compared with 22% in Canada. Nonetheless, on average, Korean jobs are harder to automate than Canadian ones are. This may be because Korean employers have found better ways to combine, in the same job, and without reducing productivity, both routine tasks and social and creative ones, which computers or robots cannot do. A gloomier explanation would be "survivor bias": the jobs that remain in Korea appear harder to automate only because Korean firms have already handed most of the easily automatable jobs to machines.

Microsoft is rolling out a new Xbox One update that brings 1440p support for the Xbox One S and X, as well as support for AMD's FreeSync technology to allow compatible displays to sync refresh rates with Microsoft's consoles. A subsequent update in May will bring 120Hz-display refresh-rate support to the Xbox One. The Verge reports: FreeSync, like Nvidia's G-Sync, helps remove tearing or stuttering usually associated with gaming on monitors, as the feature syncs refresh rates to ensure games run smoothly. Alongside this stutter-free tech, Microsoft is also supporting automatic switching to a TV's game mode. Auto Low-Latency Mode, as Microsoft calls it, will be supported on new TVs, and will automatically switch a TV into game mode to take advantage of the latency reductions. The Xbox One will also support disabling game mode when you switch to another app like Netflix. Microsoft is also making some audio tweaks with the April update for the Xbox One. New system sounds take advantage of spatial sound to fully support surround sound systems when you navigate around. Gamers who listen to music while playing can also now balance game audio against background music right inside the Xbox Guide. Other features in this update include sharing game clips direct to Twitter, dark to light mode transitions based on sunrise / sunset, and improvements to Microsoft Edge to let you download or upload pictures, music, and videos.

Nintendo Switch has been hacked, with two similar exploits released in the last 24 hours following a complete dump of the console's boot ROM. The hacks are hardware-based in nature and cannot be patched by Nintendo. The only way forward for the platform holder in fully securing the console will be to revise the Nvidia Tegra X1 processor itself, patching out the boot ROM bug. In the short term, homebrew code execution is possible and a full, touch-enabled version of Linux with 3D acceleration support is now available. I'm a little hesitant to try this out on my own Switch out of fear of messing it up and leaving me with a bricked console, but this is great news for the homebrew community.

Haiku's monthly activity report for March is out has been out for weeks now, and it contains some interesting nuggets as the team moves closer to beta, but one stood out to me: Kalisti5 got the PowerPC build working again. It is still not possible to boot PowerPC images very far, but at least it is now possible to compile them, and our buildbots are now happily doing so. I find it interesting that there's people at Haiku still working on PowerPC support. It'd be interesting if they ever manage to support Apple PowerPC hardware, if only to offer yet another choice besides MorphOS.

Windows 10 Lean appears to live up to its name: an installation is about 2GB smaller than Windows 10 Pro, and it is missing a bunch of things, such as desktop wallpaper, Registry Editor, the MMC management console, and more. Lucan reports that Lean does not seem to apply the same restrictions as S Mode, and as such it is capable of running both Universal Windows Programs from the Store and traditional Win32 applications. The latest build also has some new telephony APIs, which is fueling speculation of a Surface Phone.

After one year of managing a network of 10 servers with Cfengine I'm currently building two clusters of 50 servers with Puppet (which I'm using for the first time), and have various notes to share. With my experience I had a feeling Cfengine just isn't right for this project, and didn't consider it seriously. These servers are all running Debian GNU/Linux and Puppet felt natural because of the good Debian integration, and the number of users whom also produced a lot of resources. Chef was out of the picture soon because of the scary architecture; CouchDB, Solr and RabbitMQ... coming from Cfengine this seemed like a bad joke. You probably need to hire a Ruby developer when it breaks. Puppet is somewhat better in this regard.

Puppet master needs Ruby, and has a built-in file server using WEBrick. My first disappointment with Puppet was WEBrick. Though PuppetLabs claim you can scale it up to 20 servers, that proved way off, the built-in server has problems serving as little as 5 agents/servers, and you get to see many dropped connections and failed catalog transfers. I was forced to switch to Mongrel and Nginx as frontend very early in the project, on both clusters. This method works much better (even though Apache+Passenger is the recommended method now from PuppetLabs), and it's not a huge complication compared to WEBrick (and Cfengine which doesn't make you jump through any hoops). Part of the reason for this failure is my pull interval, which is 5 minutes with a random sleep time of up to 3 minutes to avoid harmonics (which is still a high occurrence with these intervals and WEBrick fails miserably). In production a customer can not wait on 30/45 minute pull intervals to get his IP address whitelisted for a service, or some other mundane task, it must happen within 10 minutes... but I'll come to these kind of unrealistic ideas a little later.

Unlike the Cfengine article I have no bootstrapping notes, and no code/modules to share. By default the fresh started puppet agent will look for a host called "puppet" and pull in what ever you defined to bootstrap servers in your manifests. As for modules, I wrote a ton of code and though I'd like to share it, my employer owns it. But unlike Cfengine v3 there's a lot of resources out there for Puppet which can teach you everything you need to know, so I don't feel obligated to even ask.

Interesting enough, published modules would not help you get your job done. You will have to write your own, and your team members will have to learn how to use your modules, which also means writing a lot of documentation. Maybe my biggest disappointment is getting disillusioned by most Puppet advocates and DevOps prophets. I found articles and modules most of them write, and experiences they share have nothing to do with the real world. It's like they host servers in a magical land where everything is done in one way and all servers are identical. Hosting big websites and their apps is a much, much different affair.

Every customer does things differently, and I had to write custom modules for each of them. Just between these two clusters a module managing Apache is different, and you can abstract your code a lot but you reach a point where you simply can't push it any more. Or if you can, you create a mess that is unusable by your team members, and I'm trying to make their jobs better not make them miserable. One customer uses an Isilon NAS, the other has a content distribution network, one uses Nginx as a frontend, other has chrooted web servers, one writes logs to a NFS, other to a Syslog cluster... Now imagine this on a scale with 2,000 customers and 3 times the servers and most of the published infrastructure design guidelines become laughable. Instead you find your self implementing custom solutions, and inventing your own rules, best that you can...

I'm ultimately here to tell you that the projects are in a better state then they would be with the usual cluster management policy. My best moment was an e-mail from a team member saying "I read the code, I now understand it [Puppet]. This is fucking awesome!". I knew at that moment I managed to build something good (or good enough), despite the shortcomings I found, and with nothing more than using PuppetLabs resources. Actually, that is not completely honest. Because I did buy and read the book Pro Puppet which contains an excellent chapter on using Git for collaboration on modules between sysadmins and developers, with proper implementation of development, testing and production (Puppet)environments.
