• Subdomains vs. subdirectory – status as of 2012.

  - by Quintin Par

  This following question by Jeff was in 2010 and I wanted to check how things have changed in the past 2 years. My problem: I run a site with most of the content distributed to subdomains that’s are user based. E.g: Joe.example.com John.example.com Jil.example.com So all of these subdomains have the content and the main site example.com becomes a mere dummy listing all the subdomains. Now the question is, as of 2012, how is google treating domain authority and page rank in this case? I understand the notion of page rank as page per se but when it comes to domain authority will the parent domain have the cumulative effect of the domain authority or will it be spread out?

• Creating a user called 'root'

  - by pnp

  I am creating Virtual Machines using the ubuntu-vm-builder. The syntax goes something like this: ubuntu-vm-builder kvm precise \ --domain newvm \ --dest newvm \ --arch i386 \ --hostname hostnameformyvm \ --mem 256 \ --user john \ --pass doe \ --ip 192.168.0.12 \ --mask 255.255.255.0 \ --net 192.168.0.0 \ --bcast 192.168.0.255 \ --gw 192.168.0.1 \ --dns 192.168.0.1 \ --mirror http://archive.localubuntumirror.net/ubuntu \ --components main,universe \ --addpkg acpid \ --addpkg vim \ --addpkg openssh-server \ --addpkg avahi-daemon \ --libvirt qemu:///system ; I need to enable the 'root' user account after creating each of my VMs (and supply a password for it). I was just wondering whether I can take this short-cut of supplying the username (--user) as root in this command itself. If I supply username as root to create my VMs, am I creating/enabling the root user, or just creating a user named as root? p.s.: any better ways to achieve my task are also welcome. But I don't want to manually meddle with each VM after its creation

• Histoire : le fabuleux destin de la calculatrice graphique née dans la clandestinité de l'Apple sans Steve Jobs

  Histoire : le fabuleux destin de la calculatrice graphique Née dans la clandestinité de l'Apple sans Steve Jobs Entre le licenciement de Steve Jobs par la bande à John Sculley en 1985, et son retour en 1996, bien des histoires se sont passées à Apple, que l'Histoire n'a pas forcément choisi d'oublier. Cette période, marquée par une perte du sens de produit d'Apple au profit de la recherche du... profit, a conduit à la multiplication de produits, la scission entre les équipes et une dilatation des développements amenant l'entreprise au bord du gouffre. La suite de l'histoire, on la connaît. Mais d'un tel marasme, de bonnes choses sont nées. Comme NuCalc, plus commu...

• Firefox sur le déclin ? Presque, répond un de ses co-créateurs : un avis qui ne fait pas l'unanimité

  Mise à jour du 19/05/10 Firefox est-il sur le déclin ? Presque, répond son co-créateur mais son avis ne fait pas l'unanimité Black Ross, un des créateurs de Firefox, employé aujourd'hui de Facebook, pense que son navigateur n'est plus ce qu'il était. C'est en ces termes qu'il a répondu avant-hier à une question sur l'avenir du Panda Roux : « Je pense que la Fondation Mozilla est progressivement retombées dans ses anciens travers, elle est être trop timide, trop passive et trop focalisée sur le consensus pour délivrer rapidement des produits innovants ».

• Will C++ remain viable for game engines in somewhat distant future?

  - by samual

  C++11 has opened ways, which were only dreamt by the C++ programmers. It has been three years since I have been learning C++, and I am going well. Now I want to get into vedio games. Every core of the game code I saw, was monstourously writtern in C++. My question is - If I get into serious game engine dev, and perfecting it would take, maybe say 10 years, would we still be writing game engines in C++ ?(newer standard) Or, will John Carmack, write id tech 7 in c++? note - I am strictly talking about game engines.

• Find out when a new domain appears in search results

  - by TerryB

  Does anyone know a way to perform the following: I want to know whenever a new domain starts appearing in the google search results for a particular query. For a given google search query, I'd like to receive an alert whenever a new domain pops up and starts appearing in the search results for that query. Alternatively, it would be great if you could just sort google search results by the age of the domain, making it easy to find new sites. As far as I can tell you can only sort by when the page was "last updated". Is something like this possible? EDIT: Following John's suggestion of Google Alerts. The problem with Google Alerts is that it sends you any new PAGES appearing in the search results, not just new DOMAINS.

• Mount Bluetooth USB in VirtualBox

  - by GoBrewers14

  I originally asked this question here Python Module PyBluez Error and have narrowed it down to basically I can't get VBox to recognize my bluetooth USB. I'm on a MAC OS X 10.9.2. I've installed VirtualBox as well as the Extension Pack and I've installed Ubuntu Desktop 10.04.4 on the VirtualBox. I've searched several Mac forums and this seems to be a common problem w/o a clear solution. Anyways, the question is how can I get VirtualBox to let Ubuntu recognize my bluetooth USB? I've checked 'Enable USB 2.0 EHCI Controller' and added my two bluetooth devices to the filters list. and when I click here to mount the USB I get this error message... Any ideas? Thanks, John

• PHP class data implementation

  - by Bakanyaka

  I'm studying OOP PHP and have watched two tutorials that implement user login\registration system as an example. But implementation varies. Which way will be more correct one to work with data such as this? Load all data retrieved from database as array into a property called something like _data on class creation and further methods operate with this property Create separate properties for each field retrieved from database, on class creation load all data fields into respective properties and operate with that properties separately? Then let's say I want to create a method that returns a list of all users with their data. Which way is better? Method that returns just an array of userdata like this: Array([0]=>array([id] => 1, [username] => 'John', ...), [1]=>array([id] => 2, [username] => 'Jack', ...), ...) Method that creates a new instance of it's class for each user and returns an array of objects

• Silverlight: DataContractSerializer cannot handle read only collection properties

  - by moonground.de

  Hey Stackoverflowers :) For our Silverlight Project (SL4) I'm using a Model which might contain Lists (IList<AnotherModel>). According to good practice and rule CA2227:CollectionPropertiesShouldBeReadOnly the IList properties don't have a public setter. We serialize the Model using the DataContractSerializer which is working. But when I try to deserialize, a SecurityException is thrown by DataContractSerializer's ReadObject(Stream) Method, complaining that the target property (pointing to the IList property) cannot be set due to a missing public setter. Since the DataContractSerializer is sealed and neither extendable nor flexible so I currently see no chance to add some kind of additional rules which allow to deserialize the ILists using a foreach-loop on Add() method or some other method of transferring the collection items. I've also tried to dig into DataContractSerializer source (using Reflector) to create a little fork but it looks like i'd have to dig very deep and replicating whole serialization classes doesn't seem to be a viable solution. Do you see another chance to serialize a List with no public setter using the DataContractSerializer? Thank you very much in advance for your ideas! Thomas

• Enumerating .NET assembly resources at runtime

  - by Alex_P

  I have a resource assembly with image files in it that are built using Resource or Content build action. This makes these files accessible using the Uris. However I cannot find the way to enumerate such resources. If I set the build action to Embedded Resource it becomes possible to enumerate the files with the following code: string[] resources = Assembly.GetExecutingAssembly().GetManifestResourceNames(); but it in turn makes these files inaccessible using Uris. The question is - how to enumerate resources that are compiled with either Resource or Content build action? NOTE: As Thomas Levesque pointed out it is possible to enumerate such resources by leveraging the AssemblyAssociatedContentFileAttribute, but it seems to only work for WPF Application assemblies and not for class library ones. So the question is still open.

• ASP.NET login control - can I add the FailureText as an item in a ValidationSummary?

  - by tkahn

  I'm currently working with the ASP.NET login control. I can set a custom failure text and I can add a literal on the page where the failure text is displayed if the login fails. I also have a validation summary on the page in which I collect all errors that can occur (for the moment it just validates that the user has entered a login name and a password. It would be really nice if I could add the failure text of the login control as an item in the validation summary, but I'm not sure if this is even possible? Hoping that the massive brainpower of stackoverflow can give me some pointers? Thanks! /Thomas Kahn PS. I'm coding in C#.

• Elisp performance on Windows and Linux

  - by JasonFruit

  I have the following dead simple elisp functions; the first removes the fill breaks from the current paragraph, and the second loops through the current document applying the first to each paragraph in turn, in effect removing all single line-breaks from the document. It runs fast on my low-spec Puppy Linux box using emacs 22.3 (10 seconds for 600 pages of Thomas Aquinas), but when I go to a powerful Windows XP machine with emacs 21.3, it takes almost an hour to do the same document. What can I do to make it run as well on the Windows machine with emacs 21.3? (defun remove-line-breaks () "Remove line endings in a paragraph." (interactive) (let ((fill-column 90002000)) (fill-paragraph nil))) : (defun remove-all-line-breaks () "Remove all single line-breaks in a document" (interactive) (while (not (= (point) (buffer-end 1))) (remove-line-breaks) (next-line 1))) Forgive my poor elisp; I'm having great fun learning Lisp and starting to use the power of emacs, but I'm new to it yet.

• Round prices up to nearest 5 after conversion in oscommerce

  - by Rhyso

  Hi there, A conversion question relating to prices in oscommerce: I am needing for a custom currency conversion to round the USD prices up to the nearest 5$ to avoid prices being displayed at silly prices such as $263. I am trying to convert to an int and round the following line : $curr-display_price($listing['products_price'], tep_get_tax_rate($listing['products_tax_class_id'])); ( as for some reason the price is displayed as a string, im guessing to include the currency sign) However not having much luck. Does anybody know where the root conversion takes place as it might be easier for me to round() or ceil() from there when it is a raw integer Or any other ideas of how I can round the conversion? Thanks for any help Rhys Thomas

• MySQL: SELECT a Winner, returning their rank

  - by incrediman

  Earlier I asked this question, which basically asked how to list 10 winners in a table with many winners, according to their points. This was answered. Now I'm looking to search for a given winner X in the table, and find out what position he is in, when the table is ordered by points. For example, if this is the table: Winners: NAME:____|__POINTS: Winner1 | 1241 Winner2 | 1199 Sally | 1000 Winner4 | 900 Winner5 | 889 Winner6 | 700 Winner7 | 667 Jacob | 623 Winner9 | 622 Winner10 | 605 Winner11 | 600 Winner12 | 586 Thomas | 455 Pamela | 434 Winner15 | 411 Winner16 | 410 These are possible inputs and outputs for what I want to do: Query: "Sally", "Winner12", "Pamela", "Jacob" Output: 3 12 14 623 How can I do this? Is it possible, using only a MySQL statement? Or do I need PHP as well? This is the kind of thing I want: WHEREIS FROM Winners WHERE Name='Sally' LIMIT 1 Ideas?

• Make is more OOPey - good structure?

  - by Tom

  Hi, I just want advice on whether I could improve structure around a particular class which handles all disk access functions The structure of my program is that I have a class called Disk which gets data from flatfiles and databases on a, you guessed it, hard disk drive. I have functions like LoadTextFileToStringList, WriteStringToTextFile, DeleteLineInTextFile etc which are kind of "generic methods" In the same class I also have some more specific methods such as GetXFromDisk where X might be a particular field in a database table/query. Should I separate out the generic methods from the specialised. Should I make another class which inherits the generic methods. At the moment my class is static as there is no need to have an internal state of the class. I'm not really OOPing am I? Thanks Thomas

• How active record is automatically setting up the autoincremental value of ID?

  - by piemesons

  Here this is what we are doing:-- an_order = Order.new an_order.name = "Dave Thomas" an_order.email = "[email protected]" an_order.address = "123 Main St" an_order.pay_type = "check" an_order.save Now it will insert a new row in orders table right. I m having a ID column in that table. Now suppose after inserting this record the value of the ID corresponding to this record is 100. Now how this 100 value came to know? Does the previous value of ID ie 99 (Suppose) is stored somewhere in some variable/file in the ORM layer or before inserting this value a query was fired to know about the last inserted value or database is itself doing that or anything else???
