  • Procedural landscape generation but not just fractals

    - by Richard Fabian
    In large procedural landscape games, the land seems dull, but that's probably because the real world is largely dull, with only limited places where the scenery is dramatic or tactical. Looking at world generation from this point of view, a landscape generator for a game needs to not follow the rules of landscaping, but instead some rules married to the expectations of the gamer. For example, there could be a choke point / route generator that creates hills ravines, rivers and mountains between cities, rather than cities plotted on the land based on the resources or conditions generated by the mountains and rainfall patterns. Is there any existing work being done like this? Start with cities or population centres and then add in terrain afterwards?

  • HTG Explains: How Software Installation & Package Managers Work On Linux

    - by Chris Hoffman
    Installing software on Linux involves package managers and software repositories, not downloading and running .exe files from websites like on Windows. If you’re new to Linux, this can seem like a dramatic culture shift. While you can compile and install everything yourself on Linux, package managers are designed to do all the work for you. Using a package manager makes installing and updating software easier than on Windows.

  • Blogging from 37,000ft

    - by Dave Ballantyne
    Im currently on my way to Sql Rally nordic and looking forward to a few days of full on SQL geekery and “Unleashing my inner Viking”.  I shall be speaking on Wednesday afternoon on one of my favourite subjects “Cursors are Evil”.  Ok,  so lets put it into perspective, “Evil” is a bit dramatic , but “Often use inappropriately and can cause serious performance bottlenecks” didn't have quite the same ring If you are not going to be at SQL Rally,  im going to be repeating it at the Leeds and Manchester user groups on the 23rd and 24th of November respectively.  Presenting with me on these nights will be James Boother, so make it along to those if you can.  I look forward to seeing you at one of these events.

  • Google Webmaster Tools Index dropped to Zero [closed]

    - by Brian Anderson
    Earlier this year I rebuilt my website using ZenCart. Immediately I saw a drop in index status from 59 to 0. I then signed up for Google Webmaster Tools and noticed the Index status took a dramatic drop and has never recovered. I have worked to add content and I know I am not done, but have not seen any recovery of this index since. What confuses me is when I look at the sitemap status under Optimization it shows me there are 1239 submitted and 1127 pages indexed. Most of my pages have fallen off page one for relevant search terms and some are as far back as page 7 or 8 where they used to be on the first page. I have made some changes in the past week to robots.txt and sitemap.xml, but have not seen any improvements. Can anyone tell me what might be going on here? My website is andersonpens.net. Thanks!

  • How can I get gcc to write a file larger than 2.0 GB?

    - by fred.bear
    I wanted to recompile 'xxd' (written in C), so I installed CodeBlocks as the IDE. All seemed to go well unil I discovered that I couldn't write past the 2.0 GB barrier... I've read that 'gcc' needs to be recompiled... (That sounds a bit dramatic..) I've read that I can use 'fread64()' instead of 'fread()' ... (didn't work) I've read something about a compiler options (?)... but I get lost at that point? I am surprised that it didn't work out-of-the-box, as I thought the 2.0 GB limit was ancient history as far as defaults go ... wrong again?:( My OS is 32-bit, on 32-bit hardware. The gcc version report in as: gcc (Ubuntu 4.4.3-4ubuntu5) 4.4.3 Is there a simple way around this issue? PS.. I was fascinated by the WARNINGS: section of 'info xxd' (..only on Linux ;)

  • Bet on Sharepoint 2010 Workflows?

    - by mbr
    I am looking into Sharepoint 2010 currently and it seems to me the workflow engine being used is based on WWF 3.5. I wonder if it's a good idea to do this as WWF has been gone through dramatic changes with version 4. I wonder if the investments would be save.

  • Is there an alternative to die?

    - by TJDeatwiler
    Sorry for the dramatic sounding title, just wanted to know if there is a way to prevent all types of PHP commands from executing EXCEPT one. For example, now when I kill a script using die() my pages look half broken because the bottom part of the page's html failed to load since it was being brought in using the include() function. So is there a way to tell PHP "don't allow any more commands to be executed except the include function" ?

  • Tools for analyzing performance of SQL Server/Express?

    - by Adam Crossland
    The application that I have customized and continue to support for my client is seeing dramatic performance problems in the field. Simple queries on rather small datasets take over a minute when I would expect them to complete with sub-second times. My current theory is that SQL Server Express 2005 is too limited for the rather non-trivial demands being made of it, but I am not sure how to get about gathering data that I can use to either prove my point or allow me to move on to finding another cause. Can anyone point me toward some tools that would allow me to analyze the load on this database? Information such as simultaneous connections, execution times of individual queries, memory usage, heck just any profiling data at all would be a help. Many thanks.

  • How can I speed up a MySQL retore from a dump file?

    - by Dave Forgac
    I am restoring a 30GB database from a mysqldump file to an empty database on a new server. When running the SQL from the dump file, the restore starts very quickly and then starts to get slower and slower. Individual inserts are now taking 15+ seconds. The tables are MyISAM. The server has no other active connections. SHOW PROCESSLIST; only shows the insert from the restore (and the show processlist itself). Does anyone have any ideas what could be causing the dramatic slowdown? Are there any MySQL variables that I can change to speed the restore while it is progressing?

  • GWB | First Blogger Suggestion - More Customization To Skins

    - by Geekswithblogs Administrator
    The first suggested item (and only at this point) was a higher level of skin customization on Geekswithblogs.net. Currently we have over 10 skins to pick from and the ability to change the CSS for those skins. In the skins list, you will find one labeled Naked that doesn't add any formatting, but allows you to define what items look like and what gets displayed. I understand our skin approach is not good by any means and needs a dramatic update. Here is what we came up with in our conversation with the blogger. Better tools for editing CSS from the serverPreview of changes before publishingRetrievable CSS configurations for different custom themesBetter image upload for use of custom themesMore skins selectionUpdated current skins to fix formatting issues with newer browsers and Firefox/Opera/ChromeI would really like to gauge your feedback on these items to see what is important. I know one of my biggest complaints I get is customizable themes, but typically users don't know about the options so we have done a bad job of explaining what is possible and showing every user how to do so. We have a public tutorial system we once tried and wanted it to be member managed as well and the GWB staff contributing, but that went downhill at some point. Maybe it is time to kick that back into gear for the new bloggers we have added over the past couple of years.What do you think? What else is on your mind?

  • Flash Technology Can Revolutionize your IT Infrastructure

    - by kimberly.billings
    A recent article in the Data Center Journal written by Mark Teter outlines how flash is becoming a disruptive technology in the data center and how it will soon replace HDDs in the storage hierarchy. As Teter explains, the drivers behind this trend are lower cost/performance and power savings; flash is over 100x faster for reads than the fastest HDD, and while it is expensive, it can produce dramatic reductions in the cost of performance as measured in Input/Outputs per second (IOPS). What's more, flash consumes 1/5th the power of HDD, so it's faster AND greener. Teter writes, "when appropriately used, flash turns the current economics of IT performance on its head. That's disruptive." Exadata Smart Flash Cache in the Sun Oracle Database Machine makes intelligent use of flash storage to deliver extreme performance for OLTP and mixed workloads. It intelligently caches data from the Oracle Database replacing slow mechanical I/O operations to disk with very rapid flash memory operations. Exadata Smart Flash Cache is the fundamental technology of the Sun Oracle Database Machine that enables the processing of up to 1 million random I/O operations per second (IOPS), and the scanning of data within Exadata storage at up to 50 GB/second. Are you incorporating flash into your storage strategy? Let us know! Read more: "Flash technology can revolutionize your IT infrastructure", The Data Center Journal, March 30, 2010.

  • Mark Hurd Believes HR is the Next Major Revenue Driver: Read His Latest LinkedIn Influencer Blog

    - by kristin.jellison
    “Most CEOs realize they need to make some dramatic changes in how they recruit people, align and manage performance, make compensation decisions, and optimize talent,” Oracle President Mark Hurd writes. The key issue, he explains, is that many CEOs aren’t equipping their HR teams with the tools and resources they need to unlock employees’ full value. This oversight is keeping HR organizations walled off from revenue generation and customer engagements—two chief sources of value for a company. So what is a CEO to do, given tightening budgets, a sluggish economy and a rapidly changing workforce? Hurd’s answer: invest in a modern Human Capital Management (HCM) system—one equipped with built-in intelligence and predictive analytics capabilities. To find out more about how to deliver effective HCM transformations, read Mark Hurd’s full article, “How CEOs Can Transform HR into a Revenue Driver” and visit the Oracle HCM Cloud Service site. We also encourage you to log into your LinkedIn account and “Follow” Mark to receive future posts. Share the link to his blog with your networks via Twitter, Facebook and other social media channels.

  • Someone using my website for Email and significant increase in spam

    - by Joy
    Let me give you the background in context so that you know the full story. Last summer my web guy (he put my website together) got in a fight with someone who attempted to register on my site using the name of my company as part of his user name. I was not aware of this at all until it had escalated dramatically. I don't know why my web guy was so unprofessional in his response to this person. I really don't know him - met him via SCORE and have never met in person. He is a vendor. Anyway, this guy who got into it with my web guy then threatened to do all he could to hurt my business and said he was internet savvy, etc. So, nothing seemed to happen for a while then not long ago this guy attempted to send me a friend request on Linkedin. After his behavior I declined it. Shortly afterwards I began seeing a dramatic increase in spammers posting comments on the blog part of my site. Just lately I have been receiving Emails from a variety of names but all with the "@___" that I own - for my business. I had additional security added so now they have to register in order to comment on my blog and I am seeing a lot of registration attempts from the same (and similar) IP addresses with bogus names and weird Email addresses being blocked. So, it is not creating more work as it is all automatic. The Email addresses are of more concern. Is there a way to identify a person through an IP address or a place to report the behavior or the Email usage? This guy lives in South Carolina so he is not overseas. Any help/advice you can provide will be greatly appreciated. Thanks Joy

  • CERN Announces the Discovery of a Higgs-Boson-like Particle

    - by Jason Fitzpatrick
    CERN scientists dropped a press release today indicating they’ve found a particle consistent with the long sought after Higgs Boson particle–the “God” particle, that could help radically refine our understanding of Standard Model of Particle Physics. For years scientists at CERN have been harnessing the power of the Large Hadron Collider to answer fundamental questions about the nature of particles and the universe around us. In the above video John Ellis, a theoretical physicist, answers the question “What is the Higgs Boson?” The video pairs nicely with the CERN press release: “We observe in our data clear signs of a new particle, at the level of 5 sigma, in the mass region around 126 GeV. The outstanding performance of the LHC and ATLAS and the huge efforts of many people have brought us to this exciting stage,” said ATLAS experiment spokesperson Fabiola Gianotti, “but a little more time is needed to prepare these results for publication.” “The results are preliminary but the 5 sigma signal at around 125 GeV we’re seeing is dramatic. This is indeed a new particle. We know it must be a boson and it’s the heaviest boson ever found,” said CMS experiment spokesperson Joe Incandela. “The implications are very significant and it is precisely for this reason that we must be extremely diligent in all of our studies and cross-checks.” “It’s hard not to get excited by these results,” said CERN Research Director Sergio Bertolucci. “ We stated last year that in 2012 we would either find a new Higgs-like particle or exclude the existence of the Standard Model Higgs. With all the necessary caution, it looks to me that we are at a branching point: the observation of this new particle indicates the path for the future towards a more detailed understanding of what we’re seeing in the data.” How to Use an Xbox 360 Controller On Your Windows PC Download the Official How-To Geek Trivia App for Windows 8 How to Banish Duplicate Photos with VisiPic

  • yet another question about migrating to Java

    - by aloneguid
    Hi, There are plenty similar questions, but maybe responses to this one will save a developer's life :) I want to migrate to Java. The reasons are very clear: all the .NET vacancies are client and windows oriented (Silverlight developer, ASP.NET developer, WPF developer etc.) and none of them are any interest to me. I worked with .NET since it's beginning as our company decided to invest in .NET having C++ stack and all the natual problems, so I was just blindly following and actually enjoyed it as the products were mostly server oriented with mixed C++/C# code. Today I have beforementioned problem - can't find an inspiring job. I'd rather kill myself than start working on a Silverlight or WPF project. Searching Java vacancies shows promising results, however they all require a huge java-related technology stack and experience. The question is is there any chance to find a job quickly and without dramatic salary drop (I know that Java guys are usually better paid, so there must be a kind of a credit) and if not, how must time and effort does it take to migrate (my .NET knowledge mostly includes server-oriented technologies like NHibernate, WCF, threading, sockets, ASP.NET web services, Enterprise Library, NInject etc etc etc, and (still) some C++ leftovers). Thanks!

  • Different methods of ammo resupply

    - by Chris Mantle
    I'm writing a small game at the moment. Presently, I have one or two design elements that aren't locked down yet, and I wanted to ask for input on one of these. For dramatic effect, the player's character in my game is immobilised, alone and has a supposedly limited amount of ammo for their weapons. However, I would like to periodically resupply the player with ammo (for the purpose of balancing the level of difficulty and to allow the player to continue if they're doing well). I'm trying to think of a method of resupply that's different to the more familiar strategies of making ammo magically appear or having the antagonists drop some when they die. I'd like to emphasise the notion of the player's isolation as much as possible, and finding a way of 'sneaking' ammo to the player without removing too much of that emphasis is basically what I'm trying to think of (it's definitely a valid argument that resupplying the player removes it anyway) I have considered a sort of simple in-game 'store', where kills get you points that you can spend on ammo for your favourite weapon. This might work well, and may also be good for supporting a simple micro-transaction business model within the game. However, you'd have to pause the game often to make purchases, which would interrupt the action, and it works against the notion of isolation. Any thoughts?
