Hello Games is a small development studio, only employing 10 people. But
they’re building a game, No Man’s Sky, that’s enormous — effectively infinite.
Its universe is procedurally generated, from the star systems down to individual
species of plant and animal life. The engine running the game is impressively
optimized. A planet’s characteristics are not computed ahead of time — terrain
and lifeforms are randomly generated on the fly as a player explores it. But, of
course, that created a problem for the developers — how do they know their
procedural generation algorithms don’t create ridiculous life forms or
geological formations? They solved that by writing AI bot software that
explores the universe and captures brief videos, which are then converted to GIF
format and posted on a feed the developers can review. The article goes into a
bit more detail on how the procedural generation works, and how such a small
studio can build such a big game.

Physicists have resurrected a particle that may have existed in the first hot moments after the Big Bang. Arcanely called Zc(3900), it is the first confirmed particle made of four quarks, the building blocks of much of the Universe’s matter (abstract one, abstract two). Until now, observed particles made of quarks have contained only three quarks (such as protons and neutrons) or two quarks (such as the pions and kaons found in cosmic rays).
Switch Fringe is a relatively new not-for-profit annual music and arts festival in the UK town of Ipswich, and this year’s program features a full page map of the town with details about each venue. Unlike most other maps this one is in the form of a Zelda level. This is in part due to this year’s theme ‘Re-imagining Ipswich,’ that PixelH8 is coming out of semi-retirement to play a gig during the proceedings and possibly due to the fact that the map’s designer — The Decibel Kid — spent too much time playing Zelda on a Gameboy Color during the first Web bubble.
The Linux Foundation’s UEFI secure boot pre-bootloader is still in the works, and has been modified substantially so that it allows any Linux version to boot through UEFI secure boot. The reason for modifying the pre-bootloader was that the current version of the loader wouldn’t work with Gummiboot, which was designed to boot kernels using BootServices->LoadImage(). Further, the original pre-bootloader had been written using ‘PE/Coff link loading to defeat the secure boot checks.’ As it stands, anything run by the original pre-bootloader must also be link-loaded to defeat secure boot, and Gummiboot, which is not a link-loader, didn’t work in this scenario. This is the reason a re-write of the pre-bootloader was required and now it supports booting of all versions of Linux.
Also in UEFI news: Linus Torvalds announced today that the flaw which was bricking some Samsung laptops if booted into Linux has been dealt with.
SpringOne 2GX Highlight: How to build Big Data Pipelines for Hadoop using OSS (Costin Leau)
An announcement from the SpringSource Community came yesterday, and apparently the Spring Framework 3.2 M2 has been released! As always, it’s currently available from the SpringSource Repository and they even offer a quick tutorial on resolving any dependency issues (artifacts) via Maven that you may have if you’re not familiar with Maven yet (you really should be…) The complete distribution zip is available as usual from the SpringSource community download site.
Highlights from 3.2 M2 include:
- Asynchronous @Controller method support now complete (blog post)
- Many additional Spring MVC improvements, including plenty of REST support, e.g. content negotiation.
- Spring TestContext improvements
- Spring Expression Language (SpEL) improvements and fixes
- Overall, 45 bugs fixed, 11 new features and 58 improvements implemented
Chris Beams over at SpringSource Community had the following to say regarding both the 3.2 M2 Milestone as well as the upcoming 3.2-RELEASE:
“A major area of focus for 3.2 is ensuring that Spring Framework runs flawlessly on JDK7. M2 artifacts have been built, tested and published against JDK7 and we continue to test JDK6 compatibility in nightly builds as well. We encourage all Spring users on JDK7 to give M2 a spin in your development and test environments and provide as much feedback as possible prior to 3.2 GA. Thanks!
Users of @Configuration classes and Spring’s support for subclass proxies (proxy-target-class=true), please take note: it is now no longer necessary to add CGLIB as an explicit dependency to work with these features. As of 3.2 M2, we have upgraded to the new CGLIB 3.0. We repackage all net.sf.cglib classes to org.springframework.cglib and inline them directly within the spring-core JAR. This means that all @Configuration and subclass proxying functionality works out of the box in M2, and means no potential for CGLIB conflicts with other projects. Likewise, we have upgraded to the new ASM 4.0, which we continue to repackage and inline as we have done for quite some time now. Note however that we’ve eliminated the dedicated spring-asm jar in M2 in favor of including org.springframework.asm classes directly in spring-core. Both of these upgrades are good news for JDK7 users writing Spring components in dynamic JVM languages, as these new versions of CGLIB and ASM properly handle the new invokedynamic bytecode instruction introduced in JDK7.
“Bjarne Stroustrup discusses the latest version of C++, which, although not a major overhaul, offers many small upgrades to appeal to different areas of development. From the interview: ‘I like the way move semantics will simplify the way we return large data structures from functions and improve the performance of standard-library types, such as string and vector. People in high-performance areas will appreciate the massive increase in the power of constant expressions (constexpr). Users of the standard library (and some GUI libraries) will probably find lambda expressions the most prominent feature. Everybody will use smaller new features, such as auto (deduce a variables type from its initializer) and the range-for loop, to simplify code.'”
I’ve decided to try to get realcoders.org going again *before* finishing a re-write completely in Java/Spring/Etc (as I’m starting to think that with work, etc. it will take me way too long, given the amount of “free time” that I currently have (and have had for the past few years now…))
This is simply a “welcome” post, and there will be more to come shortly. I am also going to be working on the visual appearance, as this is a fairly basic (on purpose) “template” that I opted to go with, as it’s fixed width, etc. and should be *great* for code snippets, et al. However, if anyone comes across something that either doesn’t display correctly on/in your browser, or on your operating system, please feel free and drop me an email or post a comment, etc. so that I am aware of it and can hopefully take care of it as soon as possible. I’ll do my best however to ensure cross-browser compatibility as well as supporting links(1)/lynx(1) as well if at all possible.
Again, go ahead and subscribe to the RSS feed(s), feel free to share links on Facebook, etc. all I ask is that you please bear with me while I’m getting things up and “running” a bit more along the lines of what realcoders.org is supposed to be and look like, etc. This will mean quite a bit of customization, and I’m not exactly sure how to accomplish some of the tasks under WordPress as of yet, but, I will figure it out as I come across the issues and I’m sure I’ll knock out the code one way or another =]
Thanks for all of your support! If anyone is interested in being either a regular or a one-time (or once in while) contributor, please drop me a line and we’ll talk about setting you up the appropriate account type, etc.
Contiki, the open source operating system for the Internet of Things, just got a regression test framework ported over from Thingsquare Mist that allows the Contiki developers to test the entire system on 9 platforms, 4 CPU architectures, and 1021 network nodes, for every new commit.
