• Is there a modern (eg NoSQL) web analytics solution based on log files?

  - by Martin

  I have been using Awstats for many years to process my log files. But I am missing many possibilities (like cross-domain reports) and I hate being stuck with extra fields I created years ago. Anyway, I am not going to continue to use this script. Is there a modern apache logs analytics solution based on modern storage technologies like NoSQL or at least somehow ready to cope with large datasets efficiently? I am primarily looking for something that generates nice sortable and searchable outputs with the focus on web analytics, before having to write my own frontends. (so graylog2 is not an option) This question is purely about log file based solutions.

• Can't adjust brightness on a Sony Vaio T13 ultrabook

  - by Alex Barreira

  I recently installed Ubuntu 12.04 alongside Windows 7 in a Vaio T13 ultrabook. I cannot use the the Fn+F4 or Fn+F5 to change the brightness. The bubble appears indicating that brightness is being changed but with no visual impact on the screen. I've tried many solutions involving the manipulation of the /etc/default/grub file but none of them worked. Whenever I tried this manipulation the screen still didn't change, however the bubble stopped functioning properly. This is not a problem of the Fn shortcut. Even when I try to change it in the Brightness and Lock on System Settings, the bar does scroll but the screen remains unchanged. Does any one has a way around this mystery?

• How to shift development culture from tech fetish to focusing on simplicity and getting things done?

  - by Serge

  Looking for ways to switch team/individual culture from chasing latest fads, patterns, and all kinds of best practices to focusing on finding quickest and simplest solutions and shipping features. My definition of "tech fetish": Chasing latest fads, applying new technologies and best practices without considering product/project impact, focusing on micro optimization, creating platforms and frameworks instead of finding simple and quick ways to ship product features. Few examples of culture differences: From "Spent a day on trying to map database query with five complex joins in NHibernate" to "Wrote a SQL query and used DataReader to pull data in" From "Wrote super-fast JSON parser in C++" to "Used Python to parse JSON response and call C++ code" From "Let's use WCF because it supports all possible communication standards" to "REST is simple text-based format, let's stick with it and use simple HTTP handlers"

• How to save during real-time collaboration

  - by dev.e.loper

  I want multiple users to edit same document. Problem I'm facing is when a new user joins, he might see an outdated document. How do I make sure that new users get most recent changes? Some solutions I thought of: Save on every change. I don't like this solution because it will slow things down on UI and put load on db. When new user joins, trigger save on all other clients. After other clients saved, load document. With this there can be inconsistency still. Any other suggestions would be helpful.

• Suspend/hibernate doesn't work on an Asus Laptop

  - by b1ackjosh

  I'm having issues suspending 11.04 on my new Asus U30sd-XA1 laptop, it's a new laptop on the market and I'm wondering if anyone else has had this issue and maybe have a fix for it. Basically whenever I close or put the laptop to sleep the screen goes black but the video card doesn't actually turn off, then the fan spins up even faster then it was before and gets hot. I did see that some people were having similar issues on other laptops and they set the kernal back. I'm newish to ubuntu and I'm not super comfortable messing with the kernal. If anyone has any other solutions that would be great. I am not using the 520m nvidia driver because it won't load unity after it's installed. I've also heard quite a few bad things about the drivers on the ubuntu forums, so I deactivated the driver.

• How to play the sound of an object sliding on another object for a variable duration

  - by Antoine

  I would like to add sound effects to a basic 2D game. For example, a stone sphere is rolling on wood surface. Let's say I have a 2 second audio recording of this. How could I use the sample to add sound for an arbitrary duration ? So far I have two solutions in mind: a/ record the sound for an amount of time that is greater than the maximum expected duration, and play only a part of it; b/ extract a small portion of the sample and play it in a loop for the duration of the move; however I'm not sure if it makes sense with an audio wave.

• Oracle's Director NoSQL Database Product Management talks with ODBMS.ORG

  - by thegreeneman

  I was pinged by one of my favorite database technology sites today, ODBMS.ORG - informing that Dave Segleau, the Director of Oracle NoSQL Database product management spent some time talking with their editor Roberto Zicari about the product.   Its a great interview and I highly recommend the read.  I think its important to understand the connectivity that Oracle NoSQL Database (ONDB) has with BerkeleyDB, as it says a lot about the maturity of ONDB as it relates to data integrity and reliability.  BerkeleyDB has been living the NoSQL life since the beginning of this transition embracing the right tool for the job approach to data management.  Several of the biggest names in NoSQL ( e.g. LinkedIn's Voldemort ) built their NoSQL scale-out solutions leveraging the robust BerkeleyDB storage engine under their distribution architectures.  Oracle commercializing the same via ONDB makes perfect sense given the demonstrated need for this category of technology.

• Elegant ways to handle if(if else) else

  - by Benjol

  This is a minor niggle, but every time I have to code something like this, the repetition bothers me, but I'm not sure that any of the solutions aren't worse. if(FileExists(file)) { contents = OpenFile(file); // <-- prevents inclusion in if if(SomeTest(contents)) { DoSomething(contents); } else { DefaultAction(); } } else { DefaultAction(); } Is there a name for this kind of logic? Am I a tad too OCD? I'm open to evil code suggestions, if only for curiosity's sake...

• 50 Billion Served: Java Embedded on Devices

  - by Tori Wieldt

  It doesn't matter if it is 50 billion or 24 billion, just suffice it to stay that there will be MANY connected devices in the year 2020. With just 24 billion devices, they will outnumber humans six to one! So as a developer, you don't want to ignore this opportunity. What if you could use your Java skills and deploy an app to a fraction of these devices (don't be greedy, how about just, say, 118,000 of them)? Fareed Suliman, Java ME Product Manager had lots of good news for Java Developers in his presentation Modernizing the Explosion of Advanced Microcontrollers with Embedded Java at ARM TechCon in Santa Clara, CA last week. "A radical architecture shift is underway in this space, from proprietary to standards-based," he explained.  He pointed out several advantages to using Embedded Java for devices: Java is a proven and open standard. Java provides connectivity, encryption, location, and web services APIs. You don't have to focus on and keep reinventing the plumbing below the JVM. Abstracting the software from the hardware allows you to repeat your app across many devices. Abstracting the software from the hardware allows allows parallel development so you can get your app done more quickly. You already know Java (or you can hire lots of Java talent). Java is a full ecosystem, with Java Embedded plugins for IDEs like Eclipse and NetBeans. Java ME allows for in-field software upgrades. Suliman mentioned two ways developers can start using Java Embedded today:  Java ME Embedded Suite 7.0 Oracle Java Embedded Suite is a new packaged solution from Oracle (including Java DB, GlassFish for Embedded Suite, Jersey Web Services Framework, and Oracle Java SE Embedded 7 platform), created to provide value added services for collecting, managing, and transmitting data to embedded devices such as gateways and concentrators. Oracle Java ME Embedded 3.2 Oracle Java ME Embedded 3.2 is designed and optimized to meet the unique requirements of small embedded, low power devices such as micro-controllers and other resource-constrained hardware without screens or user interfaces. Think tiny. Really tiny. And think big.  Read more about Java Embedded at the Oracle Technology Network, and read The Java Source blog Java Embedded Releases from September.

• A brief note for customers running SOA Suite on AIX platforms

  - by christian

  When running Oracle SOA Suite with IBM JVMs on the AIX platform, we have seen performance slowdowns and/or memory leaks. On occasion, we have even encountered some OutOfMemoryError conditions and the concomittant Java coredump. If you are experiencing this issue, the resolution may be to configure -Dsun.reflect.inflationThreshold=0 in your JVM startup parameters. https://www.ibm.com/developerworks/java/library/j-nativememory-aix/ contains a detailed discussion of the IBM AIX JVM memory model, but I will summarize my interpretation and understanding of it in the context of SOA Suite, below. Java ClassLoaders on IBM JVMs are allocated a native memory area into which they are anticipated to map such things as jars loaded from the filesystem. This is an excellent memory optimization, as the file can be loaded into memory once and then shared amongst many JVMs on the same host, allowing for excellent horizontal scalability on AIX hosts. However, Java ClassLoaders are not used exclusively for loading files from disk. A performance optimization by the Oracle Java language developers enables reflectively accessed data to optimize from a JNI call into Java bytecodes which are then amenable to hotspot optimizations, amongst other things. This performance optimization is called inflation, and it is executed by generating a sun.reflect.DelegatingClassLoader instance dynamically to inject the Java bytecode into the virtual machine. It is generally considered an excellent optimization. However, it interacts very negatively with the native memory area allocated by the IBM JVM, effectively locking out memory that could otherwise be used by the Java process. SOA Suite and WebLogic are both very large users of reflection code. They reflectively use many code paths in their operation, generating lots of DelegatingClassLoaders in normal operation. The IBM JVM slowdown and subsequent OutOfMemoryError are as a direct result of the Java memory consumed by the DelegatingClassLoader instances generated by SOA Suite and WebLogic. Java garbage collection runs more frequently to try and keep memory available, until it can no longer do so and throws OutOfMemoryError. The setting sun.reflect.inflationThreshold=0 disables this optimization entirely, never allowing the JVM to generate the optimized reflection code. IBM JVMs are susceptible to this issue primarily because all Java ClassLoaders have this native memory allocation, which is shared with the regular Java heap. Oracle JVMs don't automatically give all ClassLoaders a native memory area, and my understanding is that jar files are never mapped completely from shared memory in the same way as IBM does it. This results in different behaviour characteristics on IBM vs Oracle JVMs.

• One True Event Loop

  - by CyberShadow

  Simple programs that collect data from only one system need only one event loop. For example, Windows applications have the message loop, POSIX network programs usually have a select/epoll/etc. loop at their core, pure SDL games use SDL's event loop. But what if you need to collect events from several subsystems? Such as an SDL game which doesn't use SDL_net for networking. I can think of several solutions: Polling (ugh) Put each event loop in its own thread, and: Send messages to the main thread, which collects and processes the events, or Place the event-processing code of each thread in a critical section, so that the threads can wait for events asynchronously but process them synchronously Choose one subsystem for the main event loop, and pass events from other subsystems via that subsystem as custom messages (for example, the Windows message loop and custom messages, or a socket select() loop and passing events via a loopback connection). Option 2.1 is more interesting on platforms where message-passing is a well-developed threading primitive (e.g. in the D programming language), but 2.2 looks like the best option to me.

• How to make Firefox windows style less space consuming?

  - by chocobai

  Firefox takes up so much space on small screens, so I'm searching for solutions that make firefox' interface less space consuming on ubuntu 12.04 with gnome3. Good examples are the chromium-style, but chromium is kind of slow in gnome3. Chromium does it, firefox on osx does it. Is this also possible on ubuntu via a custom modification or something? Here a screenshot of what I am thinking about: Firefox on OSX: https://wiki.mozilla.org/images/5/50/Firefox-4-Mockup-i06-%28OSX%29-%28TabsTop%29-%28Persona%29.png Thanks for your help.

• Interpolation gives the appearance of collisions

  - by Akroy

  I'm implementing a simple 2D platformer with a constant speed update of the game logic, but with the rendering done as fast as the machine can handle. I interpolate positions between actual game updates by just using the position and velocity of objects at the last update. This makes things look really smooth in general, but when something hits a wall/floor, it appears to go through the wall for a moment before being positioned correctly. This is because the interpolator is not taking walls into account, so it guesses the position into walls until the actual game update fixes it. Are there any particularly elegant solutions for this? Simply increasing the update rate seems like a band-aid solution, and I'm trying to avoid increasing the system reqs. I could also check for collisions in the actual interpolator, but that seems like heavy overhead, and then I'm no longer dividing the drawing and the game updating.

• How to Sync Files Between Computers Without Storing Them in the Cloud

  - by Chris Hoffman

  So you have multiple computers and you want to keep your files in sync, but you don’t want to store them on someone else’s servers. You’ll want a service that synchronizes files directly between your computers. With such a service, you can synchronize an unlimited amount of files and people can’t gain access to your files just by gaining access to an account on a server and viewing the files via the web interface. We’re focused on syncing files over the network here — either over a local network or the Internet. We’re looking for Dropbox-style solutions that don’t store files on a central server like Dropbox does.
