• Screen is very dim on an Acer Aspire 6920Z

  - by Justin

  I've been trying to figure this out for a week now, my laptops screen is on and working but you cannot see whats on the screen without shining a flashlight at it. I'm using a spare monitor by the VGA port right now to be able to use this laptop, which is kinda a pain. Been reading around a bit about this problem and it seems to be a common-ish problem it seems. I've tried to change the brightness which doesn't help whats so ever. It just happen one day after I turned off the laptop for the night. The screen flashes on for a bit at start up, then goes completely dim. Anyone with this problem and find a fix? You can search up this computers spec by the name/model in the title if you need hardware info. I never had this problem with the old Ubuntu 10.04.

• How to configure permanent autologin?

  - by DanielGibbs

  I'm trying to set up an Ubuntu 12.04 machine as a kiosk and I would like it, on boot, to automatically log in as my kiosk user "kiosk", and start the appropriate display manager, in this case blackbox. I have configured /etc/lightdm/lightdm.conf as in this question and have an appropriate /usr/share/xsessions/blackbox.desktop to launch blackbox. I managed to get initial autologin by using the dbus-send method in this question, however if I right-click and select "Exit" from blackbox, then I am taken back to the login screen. How can I configure lightdm/ubuntu to always autologin as "kiosk" instead of displaying the login screen? Or, failing that, how can I configure blackbox to not display a menu when I right-click?

• Python as a first language?

  - by user64085

  I have just started working in Information Security World. I want to learn the Python language for creating my own automated tool for Fuzzing, SQL-Injection etc. My question is I don't know much about C language (only basic knowledge) but I want to learn directly Python Language so is it good? I have seen there is lots of difference between Python and C (obviously) and for Information Security field Python = GOD so I want to know learning Python need any experience on C language? If not so can I start learning Python directly?

• Rotate sphere in Javascript / three.js while moving on x/z axes

  - by kaipr

  I have a sphere/ball in three.js which I want to "roll" arround on a x/z axis. For the z axe I could simply do this no matter what the current x and y rotation is: sphere.roll_z = function(distance) { sphere.position.z += distance; sphere.rotation.x += distance > 0 ? 0.05 : -0.05; } But how can I roll it along the x axe? And how could I properly do the roll_z? I've found a lot about quateration and matrixes, but I can't figure out how to use them properly to achieve my (rather simple) goal. I'm aware that I have to update multiple rotations and that I have to calculate how far to rotate the sphere to match the distance, but the "how" is the question. It's probably just lack of mathematical skills which I should train, but a working example/short explanation would help alot to start with.

• Setting up Oracle Linux 6 with public-yum for all updates

  - by wcoekaer

  I just wanted to give you a quick example on how to get started with Oracle Linux 6 and start using the updates we published on http://public-yum.oracle.com. Download Oracle Linux (without the requirement of a support subscription) from http://edelivery.oracle.com/linux. Install Oracle Linux from the ISO or DVD image Log in as user root Download the yum repo file from http://public-yum.oracle.com # cd /etc/yum.repos.d # wget http://public-yum.oracle.com/public-yum-ol6.repo If you want, you can edit the repo file and enable other repositories, I enabled [ol6_UEK_latest] by just setting enabled=1 in the file with a text editor. Run yum repolist to show the registered channels and you see we are including everything including the latest published RPMs. Now you can just run yum update and any time we release new security errata or bugfix errata for OL6, they will be posted and you will automatically get them. It's very easy, very convenient and actually very cool. We do a lot more than just build OL RPMs and distribute them, we have a very comprehensive test farm where we test the packages extensively.

• Examples of interesting implementations of character stats?

  - by Tchalvak

  I've got this BBG going ( http://ninjawars.net ), and the character stats currently are simplistic. I'm looking to add a few stats to the current 1/2 (strength and maximum hitpoints, essentially). I've come up with: (strength (unchanged), speed, stamina, and some others that are somewhat interesting wildcard stats). However, I'm not satisfied with how boring the effects of some of these stats are, because they're very linear. Better stat, better effects of the stat, but the stats don't interact with each-other, there's no Rock-Paper-Scissors interaction, having more is always better all the time. So what I'd really like is to see examples of interesting character stats or effects of stats? Examples that I can think of off hand: Call of Cthulu's Insanity stat (things get really weird/chaotic if you start losing sanity) White Wolf stats, to a certain extent (the stats themselves have some basic effects, and all skills effectiveness base themselves off of stats as well) What are some other ways people have used stats to check out?

• Pre-Populate the AppFabric Cache

  When I start talking to people about the caching functionality that is part of Windows Server AppFabric I am usually asked "What is the AppFabric Cache?"  The MSDN page at http://msdn.microsoft.com/en-us/library/ee790954.aspx provides a great overview (below) as well as additional information.  The Cache is defined as: "Windows Server AppFabric caching features use a cluster of servers that communicate with each other to form a single, unified application cache system.

• Nicest way to map rgb colors from html to led

  - by back_ache

  I have attached an rgb led to a color picker on a webpage and have hit the obvious problem that though the led is 8-bit like html the color rendition is very different so with the more subtle shades the led values for the color are wildly different to the html values. The brute-force method would be for me to have a lookup-table on the webserver to map the two sets of values but would ideally like to do it more elegantly Before I start listing all my 101 ideas for doing this I wondered if anyone else had come across the issue, the end-game would be to be able to abstract the color-rendition of different leds and make it available as a webservice (html value and device id in, led value out)

• Day 1 - Finding Like Minds

  - by dapostolov

  So, is being a Game Developer any different from being an IT Developer? I picture a poorly lit environment where I get to purchase my own desk lamp; I'm thinking one of those huge lava lamps that pump out so much heat you could fry an egg on it. To my right: a "great wall" of empty coke cans dwarf me. Eating my last slice of pizza I look across my desk to see a fellow developer with a smug look on his face;  he's just coded his latest module for the game and it looks like he's in nirvana. My duty, of course, is to remind him to keep focused on the job at hand. So, picking up my trusty elastic and aerodynamically crafted paper bullet I begin a 10 minute war of welts and laughter which is promptly abrupted by our Project Manager demanding more details from our morning Scrum meeting. After providing about 5 minutes of geek speak and several words of comfort to make his eyes glaze over...it hits me, the idea for the module...beckoning my developer friend over, we quickly shoo the Project Manager away and begin our brainstorming frenzy ... now, where'd I put that full can of coke? OK. OK. This isn't probably the most ideal game developer environment, but it definitely sounds fun to me...and from what I gather is nothing like most game development companies. But I'm not doing this blog series to "go pro"; like I stated in my first post I want to make a 2D game from an idea my best friend and I drummed up long, long ago. I'm in this for the passion AND I want to see how easy it is for us .Net Developers to create a game. So where do I start? Where can I find like minded individuals? What technologies are there? What do I need to make a video game? The questions are endless....AND...since I already have an idea ... lets start with ... Technology (yes, I'm a geek, live with it...) Technology OK. Predominantly, games are still made in C++ or even C. I'm not sure how much assembly code is floating around lately, however, that is not my concern. I do know C / C++ from my past, enough to even get me by, but I'm mainly interested in a recent, not-so-new, technology called XNA. What is XNA? XNA allows us .Net Developers to make 2D / 3D games for windows, Xbox*, and Windows Mobile 7*. * = for a nominal fee *cough* The following link is your one stop shop to XNA game development: http://creators.xna.com/en-US/education/gettingstarted The above site hosts information such as: - getting started - a sample/instructional shooter game in 2D / 3D with code (if I'm taking too long for you in this blog series) - downloads - starter kits... http://creators.xna.com/en-US/education/starterkits/ And of course...forums. You can also subscribe and pay for their premium membership which gets you some pretty awesome tutorials, resources, downloads, and premium community support. Some general Wiki information about XNA: http://en.wikipedia.org/wiki/XNA_%28Microsoft%29 Community Support OK. Let's move on to industry and community support. Apart from XNA, there are some really cool sites out there, I just haven't found all of them yet. However, I found a really cool Game Development website called Gamastura. You can click on the following link to get you there: http://www.gamasutra.com/ The site is 100% dedicated to "The Art & Business of Making Games". Armed with blogs, twitter, jobs/resumes and most importantly industry news; one could subscribe to the feed and got lost in the wealth of information it provides. On a side note: I remember Gamasutra being around when my best friend and I wanted to make a video game...meaning, they've been around for a while now. I think the most beneficial aspect of this site is to understand the industry you want to get into. Otherwise, it's just a cool site to keep up to date with the industry in general. Another Community Support option is LinkedIn. Amongst the land of extremely bloated achievements and responsibilities lay 3 groups (that I have found) that deal with game development.: http://www.linkedin.com/groups?gid=59205 - Game Developers http://www.linkedin.com/groups?gid=824817 - DirectX Game Developer Network http://www.linkedin.com/groups?gid=756587 - DirectX Developers The Game Developers group in LinkedIn is by far the most active of the three and could possibly provide a wealth of support. What I've done thus far: - I lightly researched the XNA technology - I looked around for some community sites to assist me - I downloaded the XNA Game Studio 3.1 on my PC and installed it on my IDE - I even tried both tutorials! http://creators.xna.com/en-US/education/gettingstarted/bgintro/chapter1   Best Regards D.

  I'm new to Ubuntu and indeed Linux systems. I have 11.04 installed on my laptop. Here's the problem. When i select a picture for the desktop background, it says that Desktop Background has been changed but the changes do not apply right away. It is only after I have restarted the system that the changes will appear. This did not happen before. When i first started using this OS a few months ago the changes applied immediately. So what have i done that made this start acting wonky. Thank you for any help.

• As a programmer how do I plan to learn new things in my spare time

  - by priyank patel

  I am a Asp.Net/C# developer, I develop few projects in my spare time. I try to utilize my time as much as I can. I have been working for past 7 months. Suddenly these days I am a bit worried about learning the new stuff that is there for me as a programmer. I develop in my spare time so I don't get enough time to read books or blogs. So my question to some of you guys is how should I plan to learn new things, should I at least dedicate two-three evenings for new stuff, maybe ebooks while travelling is a good option too. How do you people plan to learn,should I also start to develop with whatever I learnt? As far as learning is concerned, should I just pick up the basics and then implement it or I should seek deeper understanding of the subject?

• SQL Server 2008 Service Pack 1 and the Invoke or BeginInvoke cannot be called error message

  - by Jeff Widmer

  When trying to install SQL Server 2008 Service Pack 1 to a SQL Server 2008 instance that is running on a virtual machine, the installer will start:   But then after about 20 seconds I receive the following error message: TITLE: SQL Server Setup failure. ----------------------------- SQL Server Setup has encountered the following error: Invoke or BeginInvoke cannot be called on a control until the window handle has been created. ------------------------------ BUTTONS: OK ------------------------------ Searching for this issue I found that several people have the same problem and there is no clear solution.  Some had success with closing windows or Internet Explorer but that didn’t work for me; what did work is to make sure the SQL Server 2008 “Please wait while SQL Server 2008 Setup processes the current operation.” dialog is selected and has the focus when it first shows up.  Selected (with the current focus) it looks like this:   Without focus the dialog looks like this: Add a comment if you find out any information about how to consistently get around this issue or why it is happening in the first place.

• Does syntax really matter in a programming language?

  - by Saif al Harthi

  One of my professors says "the syntax is the UI of a programming language", languages like Ruby have great readability and it's growing, but we see a lot of programmers productive with C\C++, so as programmers does it really matter that the syntax should be acceptable? I would love to know your opinion on that. Disclaimer: I'm not trying to start an argument. I thought this is a good topic of discussion. Update: This turns out to be a good topic. I'm glad you are all participating in it.

• Upgrading Agent Controllers in Oracle Enterprise Manager Ops Center 12c

  - by S Stelting

  Oracle Enterprise Manager Ops Center 12c recently released an upgrade for Solaris Agent Controllers. In this week's blog post, we'll show you how to upgrade agent controllers. Detailed instructions about upgrading Agent Controllers are available in the product documentation here. This blog post uses an Enterprise Controller which is configured for connected mode operation. If you'd like to apply the agent update in a disconnected installation, additional instructions are available here. Step 1: Download Agent Controller Updates With a connected mode Ops Center installation, you can check for product updates at any time by selecting the Enterprise Controller from the left-hand Administration navigation tab. Select the right-hand Action link “Ops Center Downloads” to open a pop-up dialog displaying any new product updates. In this example, the Enterprise Controller has already been upgraded to the latest version (Update 1, also shown as build version 2076) so only the Agent Controller updates will appear. There are three updates available: one for Solaris 10 X86, one for Solaris 8-10 SPARC, and one for all versions of Solaris 11. Note that the last update in the screen shot is the Solaris 11 update; for details on any of the downloads, place your mouse over the information icon under the details column for a pop-up text region. Select the software to download and click the Next button to display the Ops Center license agreement. Review and click the check box to accept the license agreement, then click the Next button to begin downloading the software. The status screen shows the current download status. If desired, you can perform the downloads as a background job. Simply click the check box, then click the next button to proceed to the summary screen. The summary screen shows the updates to be downloaded as well as the current status. Clicking the Finish button will close the dialog and return to the Browser UI. The download job will continue to run in Ops Center and progress can still be viewed from the jobs menu at the bottom of the browser window. Step 2: Check the Version of Existing Agent Controllers After the download job completes, you can check the availability of agent updates as well as the current versions of your Agent Controllers from the left-hand Assets navigation tab. Select “Operating Systems” from the pull-down tab lets to display only OS assets. Next, select “Solaris” in the left-hand tab to display the Solaris assets. Finally, select the Summary tab in the center display panel to show which versions of agent controllers are installed in your data center. Notice that a few of the OS assets are not displayed in the Agent Controllers tab. Ops Center will not display OS instances which do not have an Agent Controller installation. This includes Enterprise Controllers and Proxy Controllers (unless the agent has been activated on the OS instance) and and OS instances using agentless management. For Agent Controllers which support an update, the version of agent software (in this example, 2083) appears to the right of the currently installed version. Step 3: Upgrade Your Agent Controllers If desired, you can upgrade agent controllers from the previous screen by selecting the desired systems and clicking the upgrade button. Alternatively, you can click the link “Upgrade All Agent Controllers” in the right-hand Actions menu: In either case, a pop-up dialog lets you start the upgrade process. The first screen in the dialog lets you choose the upgrade method: Ops Center provides three ways to upgrade agent controllers: Automatic Upgrade: If Agent Controllers are running on all assets, Ops Center can automatically upgrade the software to the latest version without requiring any login credentials to the system SSH using a single set of credentials: If all assets use the same login credentials, you can apply a single set to all assets for the upgrade process. The log-in credentials are the same ones used for asset discovery and management, which are stored in the Plan Management navigation tab under Credentials. SSH using individual credentials: If assets use different login credentials, you can select a different set for each asset. After selecting the upgrade method, click the Next button to proceed to the summary screen. Click the Finish button to close the pop-up dialog and start the upgrade job for the agent controllers. The upgrade job runs a series of tasks in parallel, and will upgrade all agents which have been selected. Once the job completes, the OS instances in your data center will be upgraded and running the latest version of Agent Controller software.

• Using JPA 2.0 with WebLogic Server 10.3.4 and Eclipse

  - by greg.stachnick

  Beginning in Oracle Enterprise Pack for Eclipse (OEPE) 11.1.1.6.1, we introduced a new feature for WebLogic Server configuration called Server Extensions. Similar in concept to project facets, Server Extensions allow us to install additional technologies, libraries, configurations, etc into an existing server runtime. WebLogic Server 10.3.4 introduces new support for Java Persistence 2.0, the new JEE 6 standard entity access. In order to start developing JPA 2.0 applications with WebLogic Server 10.3.4, a SmartUpdate patch must be applied to add and configure the EclipseLink libraries. More information on the manual EclipseLink installation and configuration can be found here. OEPE provides a Server Extension for JPA 2.0, making the addition and configuration of JPA 2.0 and EclipseLink much easier. When defining a new WebLogic Server 10.3.4 configuration, simply click the Install link for Java Persistence 2.0 and OEPE will take care of the WebLogic Server enablement for JPA 2.0.

• Detecting Duplicates Using Oracle Business Rules

  - by joeywong-Oracle

  Recently I was involved with a Business Process Management Proof of Concept (BPM PoC) where we wanted to show how customers could use Oracle Business Rules (OBR) to easily define some rules to detect certain conditions, such as duplicate account numbers, duplicate names, high transaction amounts, etc, in a set of transactions. Traditionally you would have to loop through the transactions and compare each transaction with each other to find matching conditions. This is not particularly nice as it relies on more traditional approaches (coding) and is not the most efficient way. OBR is a great place to house these types’ of rules as it allows users/developers to externalise the rules, in a simpler manner, externalising the rules from the message flows and allows users to change them when required. So I went ahead looking for some examples. After quite a bit of time spent Googling, I did not find much out in the blogosphere. In fact the best example was actually from...... wait for it...... Oracle Documentation! (http://docs.oracle.com/cd/E28271_01/user.1111/e10228/rules_start.htm#ASRUG228) However, if you followed the link there was not much explanation provided with the example. So the aim of this article is to provide a little more explanation to the example so that it can be better understood. Note: I won’t be covering the BPM parts in great detail. Use case: Payment instruction file is required to be processed. Before instruction file can be processed it needs to be approved by a business user. Before the approval process, it would be useful to run the payment instruction file through OBR to look for transactions of interest. The output of the OBR can then be used to flag the transactions for the approvers to investigate. Example BPM Process So let’s start defining the Business Rules Dictionary. For the input into our rules, we will be passing in an array of payments which contain some basic information for our demo purposes. Input to Business Rules And for our output we want to have an array of rule output messages. Note that the element I am using for the output is only for one rule message element and not an array. We will configure the Business Rules component later to return an array instead. Output from Business Rules Business Rule – Create Dictionary Fill in all the details and click OK. Open the Business Rules component and select Decision Functions from the side. Modify the Decision Function Configuration Select the decision function and click on the edit button (the pencil), don’t worry that JDeveloper indicates that there is an error with the decision function. Then click the Ouputs tab and make sure the checkbox under the List column is checked, this is to tell the Business Rules component that it should return an array of rule message elements. Updating the Decision Service Next we will define the actual rules. Click on Ruleset1 on the side and then the Create Rule in the IF/THEN Rule section. Creating new rule in ruleset Ok, this is where some detailed explanation is required. Remember that the input to this Business Rules dictionary is a list of payments, each of those payments were of the complex type PaymentType. Each of those payments in the Oracle Business Rules engine is treated as a fact in its working memory. Implemented rule So in the IF/THEN rule, the first task is to grab two PaymentType facts from the working memory and assign them to temporary variable names (payment1 and payment2 in our example). Matching facts Once we have them in the temporary variables, we can then start comparing them to each other. For our demonstration we want to find payments where the account numbers were the same but the account name was different. Suspicious payment instruction And to stop the rule from comparing the same facts to each other, over and over again, we have to include the last test. Stop rule from comparing endlessly And that’s it! No for loops, no need to keep track of what you have or have not compared, OBR handles all that for you because everything is done in its working memory. And once all the tests have been satisfied we need to assert a new fact for the output. Assert the output fact Save your Business Rules. Next step is to complete the data association in the BPM process. Pay extra care to use Copy List instead of the default Copy when doing data association at an array level. Input and output data association Deploy and test. Test data Rule matched Parting words: Ideally you would then use the output of the Business Rules component to then display/flag the transactions which triggered the rule so that the approver can investigate.

• using x11 forwarding with ssh and vnc?

  - by simona

  I am working on a remote cluster via ssh with the -X option, because I need to visualize data and graphs, over a vpn protocol. Sometime due to the instability of the internet connection I lose my session. They told me I could use vnc in order to not lose my current session, so that if the internet connection drops I can reconnect and continue with my previously open session. What I do is to log in the remote cluster 'remote.cluster' and type vncserver :1 then I open another terminal on my system and I type ssh -C -NL 5901:remote.cluster:5901 [email protected] & Then I start vinagre on my system and I connect using ssh protocol. The problem is that I do not have x11 forwarding and I cannot open windows. If I try to connect using the vnc protocol with vinagre it doesn't connect, because I get something as connection timeout. What should I do?

• Proper way to create and work with a subdomain?

  - by Genadinik

  My site got effected by Panda, and I am trying to see if making a subdomain would work. The site is comehike.com, and I created a subdomain which is currently empty at hiking.comehike.com I have a directory /outdoors that has some high quality hand-written articles. I want to put those into the new subdomain to see what would happen. My questions are: Should I just copy and paste the files for those pages into the new subdomain's folder, and just change all the links in all my pages from the original domain to the new subdomain? Should I just do a 301 redirect to the new subdomain? Since test.site.com and www.site.com are different domains, will the new page have to start from scratch in terms of Pagerank, and its rankings in the SERPs?

• Best S.E.O. practice for backlinking etc

  - by Aaron Lee

  I'm currently working on a website that I am really looking to optimise in terms of search engines, i've been submitting between 5-20 directory submissions daily, i've validated and optimised my code and i've joined a lot of forums etc to speak of the website in question, however, I don't seem to be making much of an impact in terms of Google. I know that S.E.O. takes a while to start making an impact, and that Google prefers sites that a regularly updated and aged, but are there any more practices that can really help with organic results in Search engines. I have looked on Google itself, and a few other SE's but nobody is willing to talk about extensive S.E.O. practices as they normally don't want people knowing their formula's for S.E.O., also does anyone know of a decent piece of software that really looks into the in's and out's of your page and provides feedback, I usually use http://www.woorank.com, but only using one program doesn't show if it's exactly correct in what it's saying. If anyone could help it would be much appreciated, thank you very much.

• Turn your laptop into a wireless Access Point with Windows 7!

  - by David Nudelman

  Windows 7 offers a very cool feature where you can connect multiple devices to any wired and wireless network connection (hotel, cable, 3G, UMTS, EDGE, WIFI, RJ45, Ethernet, etc.) by turning your own laptop into a wireless AP (Access Point) to relay those devices not directly connected to the internet. For this just enter these two commands to an elevated (right click on CMD.EXE, run as administrator): netsh wlan set hostednetwork mode=allow ssid=YOURFRIENDLYSSID key=SOMEPASSWORD netsh wlan start hostednetwork At this point, if Internet Connection Sharing (ICS) is setup, anyone can connect to your SoftAP (if they know the PWD of course) and the traffic will be sent through whatever adapter you want. You can actually bridge it across an entirely different adapter... or the same on a different Wifi LAN. A GUI to set this up can be downloaded for free here: http://www.connectify.me/

• Azure Blob storage defrag

  - by kaleidoscope

  The Blob Storage is really handy for storing temporary data structures during a scaled-out distributed processing. Yet, the lifespan of those data structures should not exceed the one of the underlying operation, otherwise clutter and dead data could potentially start filling up your Blob Storage Temporary data in cloud computing is very similar to memory collection in object oriented languages, when it's not done automatically by the framework, temp data tends to leak. In particular, in cloud computing,  it's pretty easy to end up with storage leaks due to: Collection omission. App crash. Service interruption. All those events cause garbage to accumulate into your Blob Storage. Then, it must be noted that for most cloud apps, I/O costs are usually predominant compared to pure storage costs. Enumerating through your whole Blob Storage to clean the garbage is likely to be an expensive solution. Lokesh, M
