  • Adaptive Characters: AI Solution Needs a Problem

    - by Roger F. Gay
    Have sophisticated adaptive programming, will travel - so to speak. I'm part of a group that developed sophisticated learning / adaptive software for robotics. The system "thinks" via its simulator, building and adapting code on its own; and then carries out the best solution. The software can also adapt to new situations, etc. http://mensnewsdaily.com/2007/05/16/robobusiness-robots-with-imagination/ It's easy to imagine using it with automated game characters that will adapt to the players moves and style - the easiest example would be fighting. The more the simulated fighter fights with the human player, the more it learns to counter that players fighting skills. But there should be more. Anyone have any ideas as to how adaptive characters might be interesting in games?

  • The Future According to Films [Infographic]

    - by Jason Fitzpatrick
    Curious what the future will look like? According to movie directors, casting their lens towards the future of humanity, it’s quite a mixed bag. Check out this infographic timeline to check out the next 300,000 years of human evolution. A quick glance over the timeline shows a series of future where things can quickly go from the fun times to the end-of-the-world times. We’d like to, for example, live it up in the Futurama future of 3000 AD and not the Earth-gets-destroyed future of Titan A.E’s 3028. Hit up the link below for a high-res copy of the infographic.

  • Copyright of pictures upload to a website?

    - by All
    I want to run a website like stock photos. How can I be sure that the uploader is real copyright holder of the picture? Is it possible to leave the responsibility of this copyright claim to the uploader or at last the webmaster is responsible for the website content? It generally confuses me, as for example, stock photo websites needs form signed by the model for photos showing human face. How they can be sure that the signature actually belongs to the model? How they keep them safe from possible lawsuit in this case (e.g. if selling photos of a models with a fake signature?)

  • What user-friendly term should I use for a view that lives under a tab in a tab bar app?

    - by Emile Cormier
    My app uses a tab bar controller. In the user documentation, I'm not sure what name to use for a view that lives under a tab. For example, the app has a Settings tab. In the user documentation, I have a sentence that goes something like this: This threshold can be adjusted in the Settings tab. "Settings tab" is not terribly user-friendly. What would be a better term than "tab"? I've looked though Apple's Human Interface Guideline, but I can't find what would be the official user-friendly term for "view that lives under a tab".

  • Does text size and placement on page have an effect on seo

    - by sam
    I was wandering seeing as Google and others keep trying to get more and more 'human' in terms of rating whats good and whats spam, is it known if they take into account the size of a heading ie. an thats font size is 40px is going to speak allot more to the user than a thats font size is 14px.. similarly does placement factor ? ie. a 300 word article at the bottom of a landing page (not in the footer but bellow the useful content) would just be there for seo purposes. i know they look at if your doing things like text-indent:-9999px; and white text on a white background, but what about these more border line practices that both have legitimate uses but also the possibility to be spammy

  • 1 Zettabyte Is Equal to 1 Million Petabytes

    - by Gopinath
    Geeks recently coined a new English term, Zettabyte, to measure the rapidly growing digital information footprint. So what is a Zettabyte? A Zettabyte is equal to 1 million Petabytes or 1 trillion terabytes and 1 quadrillion gigabytes. Symbol To Represent Zettabyte According to wikipedia the symbol ZB is used to represent a Zettabyte. So we can write 10 ZB to represent 10 Zettabytes. Human’s Digital Output Will be 1.2 Zettabytes By End Of 2010 Are you wondering why do we need a term to measure digital data? Tech research firm IDC has recently published a report that estimates current digital footprint created by us so far at 8 million Petabytes – the equivalent of 8,000,000,000,000 GB. This foot print is expected to pass 1.2 Zettabytes by the end of 2010. cc image credit:flickr Join us on Facebook to read all our stories right inside your Facebook news feed.

  • Distance Education in Computer Science - HCI

    - by Rionmonster
    I have been a software engineer / graphic designer for a few years and have recently been considering furthering my education in the field. (It was actually a very generous Christmas present) I would primarily be interested in something like Human Computer Interaction or a similar "creative technology" that involves heavy UI/UX Design, prototyping or Information Architecture. Anyways - I still plan on working full-time and was looking into part-time distance programs and was wondering if anyone had some experience with pursuing a similar degree (either from a distance or in-person) and could share their experiences. Thanks!

  • How i can sign and/or group a specific set of vertices in a 3D file container like OBJ ? - in Blender

    - by user827992
    I would like to export a 3D model with each part having a name or a label if you will. For example i would like to export a model of an human body and name each part in specifics vertex groups like: left hand, right hand, right foot, head, ears, ... and you got the idea; so i can have a single 3D model that i can explode in various parts if needed. If there is a better technique about how to mark vertex groups in a 3D file please share your solution. As 3D editor i use Blender.

  • Evidence for automatic browsing - Log file analysis

    - by Nilani Algiriyage
    I'm analyzing web server logs both in Apache and IIS log formats. I want to find the evidence for automatic browsing, like web robots, spiders, bots, etc. I used python robot-detection 0.2.8 for detecting robots in my log files, but I know there may be other robots (automatic programs) which have traversed through the web site but robot-detection can not identify. So I want to ask: Are there any specific clues that can be found in log files that human users do not leave but automated software would? Do they follow a specific navigation pattern? I saw some requests for favicon.ico - does this implicate that it is a automatic browsing?. I found this article and this question with some valuable points.

  • Are programming languages perfect?

    - by mohabitar
    I'm not sure if I'm being naive, as I'm still a student, but a curious question came to my mind. In another thread here, a user stated that in order to protect against piracy of your software, you must have perfect software. So is it possible to have perfect software? This is an extremely silly hypothetical situation, but if you were to gather the most talented and gifted programmers in the world and have them spend years trying to create 'perfect' software, could they be successful? Could it be that not a single exploitable bug could be created? Or are there flaws in programming languages that can still, no matter how hard you try, cause bugs that allow your program to be hijacked? As you can tell, I know nothing about security, but essentially what I'm asking is: is the reason why software is easily exploitable the fact that imperfect human beings create it, or that imperfect programming languages are being used?

  • Process development lifecycle in Oracle BPM 11g

    - by mesriniv
       Oracle BPM 11g platform provides two modeling tools tailored to different audience. The BPM Process Composer component is a web-based, role-driven, collaborative platform for discovery, design and documentation of business processes aimed at business audience. It empowers the business user to participate in the definition, feedback and design of business processes. The other modeling tool is Oracle BPM Studio that runs in the JDeveloper IDE .  Irrespective of the tool used, same BPMN and related artifacts are authored - that is , this is not import/export but just multiple tools working with same assets. In addition to BPMN 2.0, both tools provides editors for process data, organizational roles, human tasks (including assignment and user interface), business rules. The Oracle BPM design-time repository (Oracle Metadata Services Repository) is the glue that facilitates shared work environment across multiple BPM Composer and Studio clients.This document explains how to create snapshots and versions of your BPM projects and captures best practices for shared process development lifecycle. http://java.net/projects/oraclebpmsuite11g/downloads/directory/Samples/bpm-122-processdevelopment-lifecycle

  • What are best practices for testing programs with stochastic behavior?

    - by John Doucette
    Doing R&D work, I often find myself writing programs that have some large degree of randomness in their behavior. For example, when I work in Genetic Programming, I often write programs that generate and execute arbitrary random source code. A problem with testing such code is that bugs are often intermittent and can be very hard to reproduce. This goes beyond just setting a random seed to the same value and starting execution over. For instance, code might read a message from the kernal ring buffer, and then make conditional jumps on the message contents. Naturally, the ring buffer's state will have changed when one later attempts to reproduce the issue. Even though this behavior is a feature it can trigger other code in unexpected ways, and thus often reveals bugs that unit tests (or human testers) don't find. Are there established best practices for testing systems of this sort? If so, some references would be very helpful. If not, any other suggestions are welcome!

    #1 I'm very new to the ubuntu home directory encryption or rather ecryptfs folder encryption. I read about the same within Dustin's blog & tried implementing it. Problem or query is my home directory is encrypted & has a www folder ... now when I reboot the system the decryption doesnt happen at startup/boot & apache is not able to find the files rather the folder www since it is not mounted ... in order to mount it I have to login .... is there a way by which an encrypted home / private folder can be mounted at boot without human intervention ? #2 I have installed ubuntu server 11.10 & had selected "encrypt home directory" when installing the same. With ubuntu things are working transparently even after reboot & without logging in. Kindly can anyone pls explain or guide on the same ?

  • How can I test a parser for a bespoke XML schema?

    - by Greg B
    I'm parsing a bespoke XML format into an object graph using .NET 4.0. My parser is using the System.XML namespace internally, I'm then interrogating the relevant properties of XmlNodes to create my object graph. I've got a first cut of the parser working on a basic input file and I want to put some unit tests around this before I progress on to more complex input files. Is there a pattern for how to test a parser such as this? When I started looking at this, my first move was to new up and XmlDocument, XmlNamespaceManager and create an XmlElement. But it occurs to me that this is quite lengthy and prone to human error. My parser is quite recursive as you can imagine and this might lead to testing the full system rather than the individual units (methods) of the system. So a second question might be What refactoring might make a recursive parser more testable?

  • IncidentsTracker v1.2 Screenshots

    - by samkea
    he IncidentsTracker v1.2 System is a system that was developed to track Incidents happening in any particular country. It is incorporated with a maping component to enable end users search for places where an incident has happened, enter data about it and then produce reports.It's a Winforms software that was developed in a plugin style using C#  with an extensibility pattern/framework. It sits on an SQl Server backend but can also use any other databases prefered. Its Administrator just has to add the path where the database will be and it will autio create the database. This software was orignally developed to help UN Agancies and NGOs in thier work but can also be ustilised by other entities like the police, the human rights organisations, roads authority, etc etc. The development of a newer version(IncidentTracker v2) has been started in silverlight.

  • if ('constant' == $variable) vs. if ($variable == 'constant')

    - by Tom Auger
    Lately, I've been working a lot in PHP and specifically within the WordPress framework. I'm noticing a lot of code in the form of: if ( 1 == $options['postlink'] ) Where I would have expected to see: if ( $options['postlink'] == 1 ) Is this a convention found in certain languages / frameworks? Is there any reason the former approach is preferable to the latter (from a processing perspective, or a parsing perspective or even a human perspective?) Or is it merely a matter of taste? I have always thought it better when performing a test, that the variable item being tested against some constant is on the left. It seems to map better to the way we would ask the question in natural language: "if the cake is chocolate" rather than "if chocolate is the cake".

  • Eloqua Experience 2013: Mystique, Modern Marketing and Masterful Engagement

    - by Mike Stiles
    The following is a guest post from Erick Mott, a social business leader at Oracle Eloqua. There’s a growing gap between 20th century marketing and a modern marketing way of doing business. I can’t think of a better example of modern marketing in action than what more than 2,000 people experienced in San Francisco at #EE13; customer-obsession, multichannel content, and real-time engagement all coming together at one extraordinary event. This was my first Eloqua Experience as a new Oracle Eloqua employee. In weeks prior, I heard about the mystique but didn’t know what to expect. What I’ve come to understand with more clarity is everything we do revolves around customer success, and we operate and educate at all times with these five tenets in mind: 1. Targeting: Really Know Your Buyer 2. Engagement: Create a 1:1 Relationship 3. Conversion: Visualize Guided Thinking 4. Analysis: Learn What’s Working 5. Marketing Technology: Enable and Extend the Cloud Product News from Eloqua Experience 2013 We made some announcements that John Stetic, VP of Products, Oracle Eloqua covers in this brief ‘Modern Marketing Minute’ video recorded after Wednesday’s keynote; summarized below, too: Oracle Eloqua AdFocus: While understanding the impact of a specific marketing channel was formerly relegated to marketers’ wish lists, the channels we now focus on are digital, social, and mobile. AdFocus gives marketers a single platform to dynamically create, manage and measure display ads alongside owned and earned media. AdFocus enables marketers to target only key accounts or prospects you want to reach with display ads, as well as provide creative content or personalized ad copy based on their persona and activities. Oracle Eloqua Profiler: The details of what we now know about customers have expanded into a universal customer profile, which can be used to create highly targeted segments. Marketers now can take data that’s not even stored in Eloqua to help targeted and score prospects for a complete, multichannel view of the customer. Profiler gives sales reps one, detailed view of the prospect to extend views beyond Oracle Eloqua asset activity (emails, forms, page views) to any external assets stored in Oracle Eloqua. Marketing Resource Management: New capabilities create more secure and controlled access to marketing resources and data. New integrations provide greater insight into campaign resources and management through a central marketing calendar and simplify resource management. Integrated Sales and Marketing Funnel: An integrated sales and marketing funnel view gives marketing and sales users, cross-functional teams, and executive management a consistent and clear view of pipeline performance. It also quickly provides users with historical metrics across different time spans and conditions. Eloqua AppCloud: More than 20 new AppCloud partners have been added to the community, which now includes 100+ apps. Eloqua AppCloud now provides modern marketers with an even broader range of marketing applications that help expand and enrich sales and marketing efforts; easily accessible in the Topliners Community. Social Capabilities: Recent integration between Oracle Eloqua and Oracle Social Relationship Management (SRM) deliver a comprehensive, scalable and integrated modern marketing solution. New capabilities include better tracking of social activities for a more complete customer profile. Engage Facebook custom audiences with AdFocus to deliver ads and meaningful experiences through trusted social networks. Biggest and Best Eloqua Experience. There’s a lot of talk in the industry about the Marketing Cloud. At Oracle Eloqua, we have been on a mission of delivering the most advanced and integrated modern marketing technology on the planet. It’s not just a concept but reality with proven execution, as seen first-hand this week in San Francisco. In this video, Kevin Akeroyd, SVP of Oracle Eloqua, provides some highlights of what made this year’s Eloqua Experience, exceptional, including Steve Woods’ presentation about the journey of modern marketers and Andrea Ward’s conversation with Vince Gilligan, creator of the Breaking Bad television series. The 2013 Markie Awards The Oracle Eloqua Marketing Cloud was best exemplified for me as 19 Markies were awarded to customers for their exceptional creativity and results as modern marketers. Wow, what a night to remember with so many committed and talented people working to create an extraordinary experience! To learn more about how to become a modern marketer, check out these resources. We look forward to seeing you next year at Eloqua Experience. More on Erick: 20 years experience at Oracle, Ektron, Sitecore, Lyris, Habeas, Nokia, creatorbase, Mark Monitor, Cisco Systems, GlobalFluency, Sun Microsystems, Philips NV, Elm Products and CBS TV.

  • What is the worst software bug in history? [closed]

    - by Amir Rezaei
    By having for example money and human suffering as the metric. What is the worst software bug in history? Note this is a specific question. Last month automaker Toyota announced a recall of 160,000 of its Prius hybrid vehicles following reports of vehicle warning lights illuminating for no reason, and cars' gasoline engines stalling unexpectedly. But unlike the large-scale auto recalls of years past, the root of the Prius issue wasn't a hardware problem -- it was a programming error in the smart car's embedded code. The Prius had a software bug.

  • Locomotion-system with irregular IK

    - by htaunay
    Im having some trouble with locomtions (Unity3D asset) IK feet placement. I wouldn't call it "very bad", but it definitely isn't as smooth as the Locomotion System Examples. The strangest behavior (that is probably linked to the problem) are the rendered foot markers that "guess" where the characters next step will be. In the demo, they are smooth and stable. However, in my project, they keep flickering, as if Locomotion changed its "guess" every frame, and sometimes, the automatic defined step is too close to the previous step, or sometimes, too distant, creating a very irregular pattern. The configuration is (apparently)Identical to the human example in the demo, so I guessing the problem is my model and/or animation. Problem is, I can't figure out was it is =S Has anyone experienced the same problem? I uploaded a video of the bug to help interpreting the issue (excuse the HORRIBLE quality, I was in a hurry).

  • How can I repair a corrupt kernel if no others are installed?

    - by Willi Ballenthin
    I've been running Ubuntu 10.04 on my laptop for quite some time. When I went to boot it up this morning, BAM! kernel panic (which immediately lead to human panic) when loading the kernel. So I've spent much of the day troubleshooting, and my current theory is that the FS is fine, but that the kernel image may be corrupt. Let's go with this current theory for the sake of this question, as I am interested how it is done. How can I replace the kernel image if I have no bootable kernels? Can I boot to a 10.04 live CD, copy the the vmlinuz-2.6.3x... to the HD and go from there? Wouldn't I want to copy the initramfs as well, but configured for the desktop system? Can I generate this from the live CD?

  • Coherence Data Guarantees for Data Reads - Basic Terminology

    - by jpurdy
    When integrating Coherence into applications, each application has its own set of requirements with respect to data integrity guarantees. Developers often describe these requirements using expressions like "avoiding dirty reads" or "making sure that updates are transactional", but we often find that even in a small group of people, there may be a wide range of opinions as to what these terms mean. This may simply be due to a lack of familiarity, but given that Coherence sits at an intersection of several (mostly) unrelated fields, it may be a matter of conflicting vocabularies (e.g. "consistency" is similar but different in transaction processing versus multi-threaded programming). Since almost all data read consistency issues are related to the concept of concurrency, it is helpful to start with a definition of that, or rather what it means for two operations to be concurrent. Rather than implying that they occur "at the same time", concurrency is a slightly weaker statement -- it simply means that it can't be proven that one event precedes (or follows) the other. As an example, in a Coherence application, if two client members mutate two different cache entries sitting on two different cache servers at roughly the same time, it is likely that one update will precede the other by a significant amount of time (say 0.1ms). However, since there is no guarantee that all four members have their clocks perfectly synchronized, and there is no way to precisely measure the time it takes to send a given message between any two members (that have differing clocks), we consider these to be concurrent operations since we can not (easily) prove otherwise. So this leads to a question that we hear quite frequently: "Are the contents of the near cache always synchronized with the underlying distributed cache?". It's easy to see that if an update on a cache server results in a message being sent to each near cache, and then that near cache being updated that there is a window where the contents are different. However, this is irrelevant, since even if the application reads directly from the distributed cache, another thread update the cache before the read is returned to the application. Even if no other member modifies a cache entry prior to the local near cache entry being updated (and subsequently read), the purpose of reading a cache entry is to do something with the result, usually either displaying for consumption by a human, or by updating the entry based on the current state of the entry. In the former case, it's clear that if the data is updated faster than a human can perceive, then there is no problem (and in many cases this can be relaxed even further). For the latter case, the application must assume that the value might potentially be updated before it has a chance to update it. This almost aways the case with read-only caches, and the solution is the traditional optimistic transaction pattern, which requires the application to explicitly state what assumptions it made about the old value of the cache entry. If the application doesn't want to bother stating those assumptions, it is free to lock the cache entry prior to reading it, ensuring that no other threads will mutate the entry, a pessimistic approach. The optimistic approach relies on what is sometimes called a "fuzzy read". In other words, the application assumes that the read should be correct, but it also acknowledges that it might not be. (I use the qualifier "sometimes" because in some writings, "fuzzy read" indicates the situation where the application actually sees an original value and then later sees an updated value within the same transaction -- however, both definitions are roughly equivalent from an application design perspective). If the read is not correct it is called a "stale read". Going back to the definition of concurrency, it may seem difficult to precisely define a stale read, but the practical way of detecting a stale read is that is will cause the encompassing transaction to roll back if it tries to update that value. The pessimistic approach relies on a "coherent read", a guarantee that the value returned is not only the same as the primary copy of that value, but also that it will remain that way. In most cases this can be used interchangeably with "repeatable read" (though that term has additional implications when used in the context of a database system). In none of cases above is it possible for the application to perform a "dirty read". A dirty read occurs when the application reads a piece of data that was never committed. In practice the only way this can occur is with multi-phase updates such as transactions, where a value may be temporarily update but then withdrawn when a transaction is rolled back. If another thread sees that value prior to the rollback, it is a dirty read. If an application uses optimistic transactions, dirty reads will merely result in a lack of forward progress (this is actually one of the main risks of dirty reads -- they can be chained and potentially cause cascading rollbacks). The concepts of dirty reads, fuzzy reads, stale reads and coherent reads are able to describe the vast majority of requirements that we see in the field. However, the important thing is to define the terms used to define requirements. A quick web search for each of the terms in this article will show multiple meanings, so I've selected what are generally the most common variations, but it never hurts to state each definition explicitly if they are critical to the success of a project (many applications have sufficiently loose requirements that precise terminology can be avoided).
