  • What kind of screen has the best image quality for reading/programming?

    - by EpsilonVector
    I'm thinking about buying a new laptop, and while I bought my original one oblivious to the fact that there could be different quality screens out there, after seeing the screen on my sister's netbook I realized that I might have to be cautious with my next purchase. Granted, I did not confirm that the reason my sister's screen looks the way it does is due to the screen itself and not color scheme/graphics card, but I know very little about the different screen technologies and how they differ in image quality and therefore can't really tell if wondering about it even makes sense or not. So what I'm asking is: should I be worried about screen quality? And if so, what technologies should I be looking for? How do they differ and which are the best ones? What are the different elements that determine the quality of a screen and which stats should I go for in each element? For the record, I'm not interested in opinions about screen size, but picture quality for lots of reading/coding.

  • What options do individual have to fork a project?

    - by skrco
    Let's assume our example individual has an idea, engagement, ... to fork project. By project I mean any kind of software - thick client, web site, portal, service, driver, plc, ... - anything that can be programmed. Motto of question: What options do our example individual have to fork this project from the early beginning through getting collaborators and users to mature software? Here are the main subquestions: Sandbox phase: Where can he announce his idea and proposal and receive positive/negative critic and feedback? Development phase: Where can he build his team to work on this project? Yet deployed phase: Where can he schedule tasks, assign tickets and bugs to be solved? and the list can go on... What really interests me is the "sandbox phase question".

  • AI control for a ship with physics model

    - by Petteri Hietavirta
    I am looking for ideas how to implement following in 2D space. Unfortunately I don't know much about AI/path finding/autonomous control yet. Let's say this ship can move freely but it has mass and momentum. Also, external forces might affect it (explosions etc). The player can set a target for the ship at any time and it should reach that spot and stop. Without physics this would be simple, just point to the direction and go. But how to deal with existing momentum and then stopping on the spot? I don't want to modify ship's placement directly. edit: Just to make clear, the physics related math of the ship itself is not the problem.

  • Will they release a Wrox Box 4?

    - by Winston Muller
    Hi, does anyone know if there will be a Wrox Box 4? I would love to get something like that, but the latest collection of Wrox books seems to be the release for 3.5. I really need to get up to date with the latest version of .NET. I'm not sure if there will be a Wrox Box 4 though, because it looks like Wiley is now publishing Wrox books under Wiley, and not Wrox anymore. So it looks like I'm going to have to go with Professional ASP.NET 4 in C# Instead of the Wrox Box 3.5

  • How to set up a SPF record?

    - by MeltingDog
    The clients on my VPS are all getting spammed. The spam seemingly comes from their own email addresses - it is clear that somehow something got into my VPS and was able to capture all the email addresses that existed and is now using them to send spam. I was advised to set up a SPF record, but I am unsure what this is or how to go about it. After reading, I have figured out how to create one in CPanel, but I cannot find what to do with it now. Do I copy it into somewhere in my DNS records in Zone Management? Can anyone point me in the right direction?

  • can't use flash in ubuntu 13.10

    - by Orosjopie
    Since I upgraded to ubuntu 13.10, my flash isn't working anymore in firefox or opera. It only works in Google Chrome as it is included in the browser. I did check that I have flash plugin for firefox and so on installed. Everthing did work before the upgrade. When I try to install from adobe's website, it doens't pick up anymore the apt installer/ software center. You have to physically to go and look for the correct program to install flash, but I don't know where to look for it or choose it. Is there a other way like in terminal or somewhere else to reinstall it? Or what can I do?

  • One-line command to download Ubuntu ISO?

    - by James Mitch
    I want to download an Ubuntu ISO, preferably over bittorrent, and verify its integrity. Currently, the following steps are required: start web browser, go to ubuntu.com, find download link find gpg signature for the checksums get the gpg key to check gpg signature of the checksums wait until download finished gpg verifiy checksum verification Isn't there a simpler way? Just like apt-get install 12.04-64bit-ubuntu-iso apt-get install 12.04-32bit-server-iso etc.? Of course, apt-get (or whatever it would be called) should download over bittorrent to remove load from the servers. If it doesn't exist, it should probable post that at ubuntu brainstorm? Is there already such a tool? I wanted to ask before posting to brainstorm.

  • Black screen with blinking cursor! [closed]

    - by Draco
    Possible Duplicate: My computer boots to a black screen, what options do I have to fix it? From my Windows XP SP3 machine, I downloaded the live image file for Ubuntu 12.04 LTS. I then burned a bootable CD. Then I went into the BIOS and set installation settings to (first) CD drive and (second) disabled. However, when I boot I only get a black screen with a blinking cursor. After some time I might get some error messages. Even if I leave it for hours I get nothing. FYI: I don't know how to go to the GRUB menu. Please make the answers easy since I am a young beginner.

  • How can I import models from Blender into jMonkeyEngine?

    - by Nathan Sabruka
    I have some blender model files (Blender version 2.6) which I would like to use with the jMonkeyEngine SDK. However, when I use Blender's native .obj exporter, I can't import it in jMonkeyEngine (the model simply fails to import or looks messed up). I've tried importing .obj files or .blend files directly into the jMonkeyEngine SDK to no avail. I've also tried to use various OGRE exporters to export .scene and .material files, but only the .scene file is created. Is there a simple way to simply export files from Blender into the jMonkeyEngine SDK? EDIT: I seem to have found something in Blender. When I go under addons, there's a warning in the OGRE exporter; "'.mesh' output requires OgreCommandLineTools". However, I have already installed those tools under the C drive. Has anyone else encountered this issue?

  • How do functional languages handle random numbers?

    - by Electric Coffee
    What I mean about that is that in nearly every tutorial I've read about functional languages, is that one of the great things about functions, is that if you call a function with the same parameters twice, you'll always end up with the same result. How on earth do you then make a function that takes a seed as a parameter, and then returns a random number based on that seed? I mean this would seem to go against one of the things that are so good about functions, right? Or am I completely missing something here?

  • Should all new web projects build their backend based on xml/json result sets?

    - by Blankman
    If you were building a new Saas project, would it make sense to start with all of the backend services returning xml/json? Because these days you need to build for both the web and mobile devices, and having a backend that is build from the start to return xml and json, you are ready to go mobile (all services have the business logic, so you won't be repeating anything). Now the web would be MVC, so the controller would just be routing the request to your service backend, and converting the json or xml to html. The obviousl downside is that you have to build a backend, and then another web project that calls your backend. But this also goes to you favor as it forces you to seperate your concerns, and not leak business logic in your controller/view layer. Thoughts?

  • Conways Game of Life C#

    - by Darren Young
    Hi, Not sure if this is the correct place for this question or SO - mods please move if necessary. I am going to have a go at creating GoL over the weekend as a little test project : http://en.wikipedia.org/wiki/Conway's_Game_of_Life I understand the algorithm, however I just wanted to check regarding the implementation, from maybe somebody that has tried it. Essentially, my first (basic) implementation, will be a static grid at a set speed. If I understand correctly, these are the steps I will need: Initial seed Create 2d array with initial set up Foreach iteration, create temporary array, calculating each cells new state based on the Game of Life algorithm Assign temp array to proper array. Redraw grid from proper array. My concerns are over speed. When I am populating the grid from the array, would it simply be a case of looping through the array, assigning on or off to each grid cell and then redraw the grid? Am I on the correct path?

  • Implementation of instance testing in Java, C++, C#

    - by Jake
    For curiosity purposes as well as understanding what they entail in a program, I'm curious as to how instance testing (instanceof/is/using dynamic_cast in c++) works. I've tried to google it (particularly for java) but the only pages that come up are tutorials on how to use the operator. How do the implementations vary across those langauges? How do they treat classes with identical signatures? Also, it's been drilled into my head that using instance testing is a mark of bad design. Why exactly is this? When is that applicable, instanceof should still be used in methods like .equals() and such right? I was also thinking of this in the context of exception handling, again particularly in Java. When you have mutliple catch statements, how does that work? Is that instance testing or is it just resolved during compilation where each thrown exception would go to?

  • What Keeps You from Changing Your Public IP Address and Wreaking Havoc on the Internet?

    - by Jason Fitzpatrick
    What exactly is preventing you (or anyone else) from changing their IP address and causing all sorts of headaches for ISPs and other Internet users? Today’s Question & Answer session comes to us courtesy of SuperUser—a subdivision of Stack Exchange, a community-driven grouping of Q&A web sites. The Question SuperUser reader Whitemage is curious about what’s preventing him from wantonly changing his IP address and causing trouble: An interesting question was asked of me and I did not know what to answer. So I’ll ask here. Let’s say I subscribed to an ISP and I’m using cable internet access. The ISP gives me a public IP address of 60.61.62.63. What keeps me from changing this IP address to, let’s say, 60.61.62.75, and messing with another consumer’s internet access? For the sake of this argument, let’s say that this other IP address is also owned by the same ISP. Also, let’s assume that it’s possible for me to go into the cable modem settings and manually change the IP address. Under a business contract where you are allocated static addresses, you are also assigned a default gateway, a network address and a broadcast address. So that’s 3 addresses the ISP “loses” to you. That seems very wasteful for dynamically assigned IP addresses, which the majority of customers are. Could they simply be using static arps? ACLs? Other simple mechanisms? Two things to investigate here, why can’t we just go around changing our addresses, and is the assignment process as wasteful as it seems? The Answer SuperUser contributor Moses offers some insight: Cable modems aren’t like your home router (ie. they don’t have a web interface with simple point-and-click buttons that any kid can “hack” into). Cable modems are “looked up” and located by their MAC address by the ISP, and are typically accessed by technicians using proprietary software that only they have access to, that only runs on their servers, and therefore can’t really be stolen. Cable modems also authenticate and cross-check settings with the ISPs servers. The server has to tell the modem whether it’s settings (and location on the cable network) are valid, and simply sets it to what the ISP has it set it for (bandwidth, DHCP allocations, etc). For instance, when you tell your ISP “I would like a static IP, please.”, they allocate one to the modem through their servers, and the modem allows you to use that IP. Same with bandwidth changes, for instance. To do what you are suggesting, you would likely have to break into the servers at the ISP and change what it has set up for your modem. Could they simply be using static arps? ACLs? Other simple mechanisms? Every ISP is different, both in practice and how close they are with the larger network that is providing service to them. Depending on those factors, they could be using a combination of ACL and static ARP. It also depends on the technology in the cable network itself. The ISP I worked for used some form of ACL, but that knowledge was a little beyond my paygrade. I only got to work with the technician’s interface and do routine maintenance and service changes. What keeps me from changing this IP address to, let’s say, 60.61.62.75 and mess with another consumer’s internet access? Given the above, what keeps you from changing your IP to one that your ISP hasn’t specifically given to you is a server that is instructing your modem what it can and can’t do. Even if you somehow broke into the modem, if 60.61.62.75 is already allocated to another customer, then the server will simply tell your modem that it can’t have it. David Schwartz offers some additional insight with a link to a white paper for the really curious: Most modern ISPs (last 13 years or so) will not accept traffic from a customer connection with a source IP address they would not route to that customer were it the destination IP address. This is called “reverse path forwarding”. See BCP 38. Have something to add to the explanation? Sound off in the the comments.

  • Planning an Event&ndash;SPS NYC

    - by MOSSLover
    I bet some of you were wondering why I am not going to any events for the most part in June and July (aside from volunteering at SPS Chicago).  Well I basically have no life for the next 2 months.  We are approaching the 11th hour of SharePoint Saturday New York City.  The event is slated to have 350 to 400 attendees.  This is second year in a row I’ve helped run it with Jason Gallicchio.  It’s amazingly crazy how much effort this event requires versus Kansas City.  It’s literally 2x the volume of attendees, speakers, and sponsors plus don’t even get me started about volunteers.  So here is a bit of the break down… We have 30 volunteers+ that Tasha Scott from the Hampton Roads Area will be managing the day of the event to do things like timing the speakers, handing out food, making sure people don’t walk into the event that did not sign up until we get a count for fire code, registering people, watching the sharpees, watching the prizes, making sure attendees get to the right place,  opening and closing the partition in the big room, moving chairs, moving furniture, etc…Then there is Jason, Greg, and I who will be making sure that the speakers, sponsors, and everything is going smoothly in the background.  We need to make sure that everything is setup properly and in the right spot.  We also need to make sure signs are printed, schedules are created, bags are stuffed with sponsor material.  Plus we need to send out emails to sponsors reminding them to send us the right information to post on the site for charity sessions, send us boxes with material to stuff bags, and we need to make sure that Michael Lotter gets there information for invoicing.  We also need to check that Michael has invoiced everyone and who has paid, because we can’t order anything for the event without money.  Once people have paid we need to setup food orders, speaker and volunteer dinners, buy prizes, buy bags, buy speakers/volunteer/organizer shirts, etc…During this process we need all the abstracts from speakers, all the bios, pictures, shirt sizes, and other items so we can create schedules and order items.  We also need to keep track of who is attending the dinner the night before for volunteers and speakers and make sure we don’t hit capacity.  Then there is attendee tracking and making sure that we don’t hit too many attendees.  We need to make sure that attendees know where to go and what to do.  We have to make all kinds of random supply lists during this process and keep on track with a variety of lists and emails plus conference calls.  All in all it’s a lot of work and I am trying to keep track of it all the top so that we don’t duplicate anything or miss anything.  So basically all in all if you don’t see me around for another month don’t worry I do exist. Right now if you look at what I’m doing I am traveling every Monday morning and Thursday night back and forth to Washington DC from New Jersey.  Every night I am working on organizational stuff for SharePoint Saturday New York City.  Every Tuesday night we are running an event conference call.  Every weekend I am either with family or my boyfriend and cat trying hard not to touch the event.  So all my time is pretty much work, event, and family/boyfriend.  I have 0 bandwidth for anything in the community.  If you compound that with my severe allergy problems in DC and a doctor’s appointment every month plus a new med once a week I’m lucky I am still standing and walking.  So basically once July 30th hits hopefully Jason Gallicchio, Greg Hurlman, and myself will be able to breathe a little easier.  If I forget to do this thank you Greg and Jason.  Thank you Tom Daly.  Thank you Michael Lotter.  Thank you Tasha Scott.  Thank you Kevin Griffin.  Thank you all the volunteers, speakers, sponsors, and attendees who will and have made this event a success.  Hopefully, we have enough time until next year to regroup, recharge, and make the event grow bigger in a different venue.  Awesome job everyone we sole out within 3 days of registration and we still have several weeks to go.  Right now the waitlist is at 49 people with room to grow.  If you attend the event thank all these guys I mentioned above for making it possible.  It’s going to be awesome I know it but I probably won’t remember half of it due to the blur of things that we will all be taking care of the day of the event.  Catch you all in the end of July/Early August where I will attempt to post something useful and clever and possibly while wearing a fez.

  • Methods to Validate User Supplied Data

    - by clifgray
    I am working on a website where users record data from certain locations and they input an address to tag that location with a GPS coordinate. Pretty frequently those locations are tagged more than a mile away from the actual location and I am trying to implement a few ways to validate the data. Right now I am thinkiing of: having a tag of location pages for other users to say "incorrect location" so I can go one by one and fix it letting users with a decent amount of experience (reputation) edit the location GPS coordinates making the location be validated by a mod before it goes live and they make sure it is a good location Are these reasonable? I know the first will take a lot of my time and I would love some suggestions.

  • AWStats: cannot access /var/log/apache2/access.log

    - by Joril
    I installed awstats on my new Ubuntu Lucid server, but when cron tries to run it as user www-data, it complains that cannot access /var/log/apache2/access.log: Permission denied. In /usr/share/doc/awstats/README.Debian there's this paragraph: By default Apache stores (since version 1.3.22-1) logfiles with uid=root and gid=adm, so you need to either... 1) Change the rights of the logfiles in /etc/logrotate.d/apache so that www-data has at least read access. 2) As 1) but change to a specific user, and use the suEXEC feature of Apache to run as same user (and either change the right of /var/lib/awstats as well or use another directory). This is more complicated, but then the logs are not generally accessible to the server (which was probably the point of the Apache default). 3) Change awstats.pl to group adm (but beware that you are then taking the risk of allowing a CGI-script access to admin stuff on the machine!). I'd go with 1, but what are the recommended permissions to grant?

  • Ouya build experiencing odd graphical artifacts, screen half black

    - by Neeko
    I'm witnessing very odd graphical artifacts when I run my Unity game on Ouya. After the Unity splash screen, the game loads with the screen half black. This seemingly has started occurring out of the blue. It also doesn't occur in the editor or the standalone build, only on Ouya. I can't think of a single reason why this would be happening. If I open the Ouya menu screen and close it, the game returns to normal; somewhat, as there may be some artifacts lingering but the screen isn't half black like in the screen shot above. I know there's not much to go off of, but any insight into why this may be happening is greatly appreciated.

  • Customizing UPK outputs (Part 2 - Player)

    - by [email protected]
    There are a few things that can be done to give the Player output a personalized look to match your corporate branding. In my previous post, I talked about changing the logo. In addition to the logo, you can change the graphic in the heading, button colors, border colors and many other items. Prior to making any customizations, I strongly recommend making a copy of the existing Player style. This will give you a backup in case things go wrong. I'd also recommend that you create your own brand. This way, when you install the newest updates from us, your brand will remain intact. Creating your own brand is pretty easy. Make sure you have modify permissions on the publishing styles directory, if you are using a multi-user installation. Under the Publishing/Styles folder, create a new folder with your company name. Copy all the publishing styles from the UPK folder to your newly created folder. Now, when you go through the Publishing wizard, you will have two categories to choose from: the UPK category or your custom category. Now, for updating the Player output. First, the graphic that appears on the right hand side of the Player. If you're using a multi-user installation, check out the player style from your custom brand. Open the player style. Open the img folder. The file named "banner_image.png" represents the graphic that appears on the right hand side of the player. It is currently sized at 425 x 54. Try to keep your graphic about the same size. Rename your graphic file to be "banner_image.png", and drag it into the img folder. Save the package. Check in the package if you are in a multi-user installation. You've just updated the banner heading! Next, let's work on updating some of the other colors in the player. All the customizable areas are located in the skin.css file which is in the root of the Player style. Many of our customers update the colors to match their own theme. You don't have to be a programmer to make these changes, honest. :) To change the colors in the player: Make a copy of the original skin.css file. (This is to make sure you have a working version to revert to, in case something goes wrong.) Open the skin.css file from the Player package. You can edit it using Notepad. Make the desired changes. Save the file. Save the package. Publish to view your new changes. When you open the skin.css, you will see groupings like this: .headerDivbar { height: 21px; background-color: #CDE2FD; } Change the value of the background-color to the color of your choice. Note that you cannot use "red" as a color, but rather you should enter the hexadecimal color code. If you don't know the color code, search the web for "hexadecimal colors" and you'll find many sites to provide the information. Here are a few of the variables that you can update. Heading: .headerDivbar -this changes the color of the banner that appears under the graphic Button colors: .navCellOn - changes the color of the mode buttons when your mouse is hovering on them. .navCellOff - changes the color of the mode buttons when the mouse is not over them Lines: .thorizontal - this is the color of the horizontal lines surrounding the outline .tvertical - this is the color of the vertical lines on the left and right margin in the outline. .tsep - this is the color of the line that separates the outline from the content area Search frame: .tocSearchColor - this is the color of the search area .tocFrameText - this is the background color of the TOC tree. Hint: If you want to try out the changes prior to updating the style, you can update the skin.css in some content you've already published for the player (it's located in the css folder of the player package). This way, you can immediately see the changes without going through publishing. Once you're happy with the changes, update the skin.css in player style. Want to customize more? Refer to the "Customizing the Player" section of the Content Development manual for more details on all the options in the skin.css that can be changed, and pictures of what each variable controls. I'd love to see how you've customized the player for your corporate needs. Also, if there are other areas of the player you'd like to modify but have not been able to, let us know. Feel free to share your thoughts in the comments. --Maria Cozzolino, Manager of Requirements & UI Design for UPK

  • SharePointBeginners: A new group for a global noob community

    - by PeterBrunone
    Recently, a discussion broke out (go figure) on a SharePoint list that I frequent.  It had grown in size to the point where the more advanced members were sometimes turned off by the volume of questions that appeared TOO simple.  This happens all the time, as something becomes larger and specialization is necessary.Anyhoo, my response was to create the SharePoint Beginners group.  Come out and join us at http://groups.google.com/group/sharepointbeginners , where no question is too simple; all we ask is to show us that you tried to find the answer.
