• Xubuntu: how do I automatically mount external NTFS drive with writes allowed?

  - by user74372

  i would have thought mine was such a common question that there would be a simple solution already built in to xubuntu - but there isnt. i have 2 separate external hard disks and connect them to a usb port at different times - i would like them to be automatically mounted as read/write, but apparently the designers of gnome-volume-manager decided that shouldnt be possible and they are mounted as read-only in fact, i can write new files to them, but cannot then delete the new files i just wrote! is there a workaround? i read somewhere that etc/fstab doesn't apply to removable media, which are mounted by gnome-volume-manager and therefore cannot be unmounted by a user

• Booting but not rebooting from external USB hard drive, what could be the problem?

  - by user8276

  I have a Dell Inspiron 6400 laptop with a dead internal hard drive controller. It boots perfectly from CD or USB. I therefore removed the internal hard drive and installed Ubuntu 10.10 Maverick onto an external USB hard drive. It boots and runs perfectly when doing a "cold start" of the PC. However, when I choose restart/reboot in the Ubuntu menu (e.g. after an update), I get this error message from the BIOS: "No bootable devices, strike f1 to retry boot, f2 for setup utility, press f5 to run onboard diagnostics". I can make the system boot again by pressing f2 or f5 and exiting the utility without having done anything. Or, I can simply power off the system and do a new "cold start". Does anyone know the likely reason for this problem and how to fix it. It is not a big issue but an annoyance that I would like to fix if possible.

• Why is using an external USB drive or USB printer causing my system to hang?

  - by thepd

  I am having some troubles using various external hard drives and my printer, all of which I connect using USB. The majority of the time, when I connect either of these devices, my system freezes up completely after about 10 minutes. They work just fine prior to that moment. I've also not noticed any problems using a USB mouse. I'm running Ubuntu 10.10 and have tried using a newer kernel (a 2.6.36 Maverick kernel from the kernel ppa, as opposed to the default 2.6.35 one) to no avail. I'm using a Dell Studio XPS 16 (M1647) which is a sort of newish laptop and so my guess is this is probably some kind of driver bug. Is there anyway to debug these sorts of issues? I've looked through some of my logs (/var/log/messages seemed the most useful) but haven't been able to find any kind of USB related logging nor anything interesting happening prior to the hang.

• Using an external hard drive as a server and be able to connect via wifi [on hold]

  - by user289228

  OK, so i have an old external HDD(seagate 1tb) and a windows computer just in case but im trying to set it up as a server for my home at the moment but if everything goes right i want to transfer it to being a database hub for the business i work for that way i can have more then one register at a time on the same basic database. The thing is im new to the whole server part along with im not well versed with ubuntu either so what im getting at is if i can get it setup, can i connect it on ubuntu and run a linux based Point of sales program but have multiple linked to the single server? i may be able to do it via the router, i think its a belkin n600 with usb port but at this moment i dont know what it is since im not home. i just need information if this is possible and if so, a guide would be appreciated.

• How do I count Internal Logical Files (ILF) and External Inputs (EI) for a dynamic form entry page?

  - by DmytroL

  Assuming I have an applicant information entry screen, the number and types of fields on which can be defined by the system administrator, how do I go about counting the number of Internal Logical Files (ILFs) and Data Element Types (DETs) for the related data functions? So far I have come up with something like this: ILF #1 (control information): Field Metadata, 1 RET, ~3 DET (name, type, mandatory) ILF #2 (business data): Applicant Data, most likely 1 RET, but how many DET? Of course I could count it as 2 DET (Field ref, Value), but I am not sure that would be correct And when it comes to an External Input (EI), say, "Add New Applicant", things become even more complicated, because the number of DET corresponding to the user-editable fields is totally dependent on the control information in ILF #1, and I am out of ideas here... Anyone fancy to help with that? Thanks in advance!

• Does running Nexuiz gives extra pressure on Processor if you dont have external Graphics card?

  - by Curious Apprentice

  Its a rather stupid question, though I want to be sure. Does having a external graphics card can lower the stress over the processor? what kind of graphics card Ubuntu supports ? Well I'm planning to buy a graphics card for Windows 7 as I have started learning Adobe Premiere Pro. Which G card should I buy? Do i consider the card or the availability of the card drivers for Ubuntu Linux ? If I install a Graphics card and does not install its drivers can I left it unused on Ubuntu ? I don't think theres a much need for G card on Ubuntu Though.

• Flow-Design Cheat Sheet &ndash; Part I, Notation

  - by Ralf Westphal

  You want to avoid the pitfalls of object oriented design? Then this is the right place to start. Use Flow-Oriented Analysis (FOA) and –Design (FOD or just FD for Flow-Design) to understand a problem domain and design a software solution. Flow-Orientation as described here is related to Flow-Based Programming, Event-Based Programming, Business Process Modelling, and even Event-Driven Architectures. But even though “thinking in flows” is not new, I found it helpful to deviate from those precursors for several reasons. Some aim at too big systems for the average programmer, some are concerned with only asynchronous processing, some are even not very much concerned with programming at all. What I was looking for was a design method to help in software projects of any size, be they large or tiny, involing synchronous or asynchronous processing, being local or distributed, running on the web or on the desktop or on a smartphone. That´s why I took ideas from all of the above sources and some additional and came up with Event-Based Components which later got repositioned and renamed to Flow-Design. In the meantime this has generated some discussion (in the German developer community) and several teams have started to work with Flow-Design. Also I´ve conducted quite some trainings using Flow-Orientation for design. The results are very promising. Developers find it much easier to design software using Flow-Orientation than OOAD-based object orientation. Since Flow-Orientation is moving fast and is not covered completely by a single source like a book, demand has increased for at least an overview of the current state of its notation. This page is trying to answer this demand by briefly introducing/describing every notational element as well as their translation into C# source code. Take this as a cheat sheet to put next to your whiteboard when designing software. However, please do not expect any explanation as to the reasons behind Flow-Design elements. Details on why Flow-Design at all and why in this specific way you´ll find in the literature covering the topic. Here´s a resource page on Flow-Design/Event-Based Components, if you´re able to read German. Notation Connected Functional Units The basic element of any FOD are functional units (FU): Think of FUs as some kind of software code block processing data. For the moment forget about classes, methods, “components”, assemblies or whatever. See a FU as an abstract piece of code. Software then consists of just collaborating FUs. I´m using circles/ellipses to draw FUs. But if you like, use rectangles. Whatever suites your whiteboard needs best.   The purpose of FUs is to process input and produce output. FUs are transformational. However, FUs are not called and do not call other FUs. There is no dependency between FUs. Data just flows into a FU (input) and out of it (output). From where and where to is of no concern to a FU.   This way FUs can be concatenated in arbitrary ways:   Each FU can accept input from many sources and produce output for many sinks:   Flows Connected FUs form a flow with a start and an end. Data is entering a flow at a source, and it´s leaving it through a sink. Think of sources and sinks as special FUs which conntect wires to the environment of a network of FUs.   Wiring Details Data is flowing into/out of FUs through wires. This is to allude to electrical engineering which since long has been working with composable parts. Wires are attached to FUs usings pins. They are the entry/exit points for the data flowing along the wires. Input-/output pins currently need not be drawn explicitly. This is to keep designing on a whiteboard simple and quick.   Data flowing is of some type, so wires have a type attached to them. And pins have names. If there is only one input pin and output pin on a FU, though, you don´t need to mention them. The default is Process for a single input pin, and Result for a single output pin. But you´re free to give even single pins different names.   There is a shortcut in use to address a certain pin on a destination FU:   The type of the wire is put in parantheses for two reasons. 1. This way a “no-type” wire can be easily denoted, 2. this is a natural way to describe tuples of data.   To describe how much data is flowing, a star can be put next to the wire type:   Nesting – Boards and Parts If more than 5 to 10 FUs need to be put in a flow a FD starts to become hard to understand. To keep diagrams clutter free they can be nested. You can turn any FU into a flow: This leads to Flow-Designs with different levels of abstraction. A in the above illustration is a high level functional unit, A.1 and A.2 are lower level functional units. One of the purposes of Flow-Design is to be able to describe systems on different levels of abstraction and thus make it easier to understand them. Humans use abstraction/decomposition to get a grip on complexity. Flow-Design strives to support this and make levels of abstraction first class citizens for programming. You can read the above illustration like this: Functional units A.1 and A.2 detail what A is supposed to do. The whole of A´s responsibility is decomposed into smaller responsibilities A.1 and A.2. FU A thus does not do anything itself anymore! All A is responsible for is actually accomplished by the collaboration between A.1 and A.2. Since A now is not doing anything anymore except containing A.1 and A.2 functional units are devided into two categories: boards and parts. Boards are just containing other functional units; their sole responsibility is to wire them up. A is a board. Boards thus depend on the functional units nested within them. This dependency is not of a functional nature, though. Boards are not dependent on services provided by nested functional units. They are just concerned with their interface to be able to plug them together. Parts are the workhorses of flows. They contain the real domain logic. They actually transform input into output. However, they do not depend on other functional units. Please note the usage of source and sink in boards. They correspond to input-pins and output-pins of the board.   Implicit Dependencies Nesting functional units leads to a dependency tree. Boards depend on nested functional units, they are the inner nodes of the tree. Parts are independent, they are the leafs: Even though dependencies are the bane of software development, Flow-Design does not usually draw these dependencies. They are implicitly created by visually nesting functional units. And they are harmless. Boards are so simple in their functionality, they are little affected by changes in functional units they are depending on. But functional units are implicitly dependent on more than nested functional units. They are also dependent on the data types of the wires attached to them: This is also natural and thus does not need to be made explicit. And it pertains mainly to parts being dependent. Since boards don´t do anything with regard to a problem domain, they don´t care much about data types. Their infrastructural purpose just needs types of input/output-pins to match.   Explicit Dependencies You could say, Flow-Orientation is about tackling complexity at its root cause: that´s dependencies. “Natural” dependencies are depicted naturally, i.e. implicitly. And whereever possible dependencies are not even created. Functional units don´t know their collaborators within a flow. This is core to Flow-Orientation. That makes for high composability of functional units. A part is as independent of other functional units as a motor is from the rest of the car. And a board is as dependend on nested functional units as a motor is on a spark plug or a crank shaft. With Flow-Design software development moves closer to how hardware is constructed. Implicit dependencies are not enough, though. Sometimes explicit dependencies make designs easier – as counterintuitive this might sound. So FD notation needs a ways to denote explicit dependencies: Data flows along wires. But data does not flow along dependency relations. Instead dependency relations represent service calls. Functional unit C is depending on/calling services on functional unit S. If you want to be more specific, name the services next to the dependency relation: Although you should try to stay clear of explicit dependencies, they are fundamentally ok. See them as a way to add another dimension to a flow. Usually the functionality of the independent FU (“Customer repository” above) is orthogonal to the domain of the flow it is referenced by. If you like emphasize this by using different shapes for dependent and independent FUs like above. Such dependencies can be used to link in resources like databases or shared in-memory state. FUs can not only produce output but also can have side effects. A common pattern for using such explizit dependencies is to hook a GUI into a flow as the source and/or the sink of data: Which can be shortened to: Treat FUs others depend on as boards (with a special non-FD API the dependent part is connected to), but do not embed them in a flow in the diagram they are depended upon.   Attributes of Functional Units Creation and usage of functional units can be modified with attributes. So far the following have shown to be helpful: Singleton: FUs are by default multitons. FUs in the same of different flows with the same name refer to the same functionality, but to different instances. Think of functional units as objects that get instanciated anew whereever they appear in a design. Sometimes though it´s helpful to reuse the same instance of a functional unit; this is always due to valuable state it holds. Signify this by annotating the FU with a “(S)”. Multiton: FUs on which others depend are singletons by default. This is, because they usually are introduced where shared state comes into play. If you want to change them to be a singletons mark them with a “(M)”. Configurable: Some parts need to be configured before the can do they work in a flow. Annotate them with a “(C)” to have them initialized before any data items to be processed by them arrive. Do not assume any order in which FUs are configured. How such configuration is happening is an implementation detail. Entry point: In each design there needs to be a single part where “it all starts”. That´s the entry point for all processing. It´s like Program.Main() in C# programs. Mark the entry point part with an “(E)”. Quite often this will be the GUI part. How the entry point is started is an implementation detail. Just consider it the first FU to start do its job.   Patterns / Standard Parts If more than a single wire is attached to an output-pin that´s called a split (or fork). The same data is flowing on all of the wires. Remember: Flow-Designs are synchronous by default. So a split does not mean data is processed in parallel afterwards. Processing still happens synchronously and thus one branch after another. Do not assume any specific order of the processing on the different branches after the split.   It is common to do a split and let only parts of the original data flow on through the branches. This effectively means a map is needed after a split. This map can be implicit or explicit.   Although FUs can have multiple input-pins it is preferrable in most cases to combine input data from different branches using an explicit join: The default output of a join is a tuple of its input values. The default behavior of a join is to output a value whenever a new input is received. However, to produce its first output a join needs an input for all its input-pins. Other join behaviors can be: reset all inputs after an output only produce output if data arrives on certain input-pins

• Grub Rescue Unknown Filesystem Error. Grub Corrupted or Filesystem?

  - by nightcrawler

  Now it has happened twice & have been pulling my hairs now... I have installed xubuntu on my external hardisk & have been using it for about 3 months. It has three partitions, one of 500 mb mounted at /boot, 2nd one of 48gb mounted at / & the rest (out of 160gb) is ntfs partition....used as normal external storage. The last storage supposedly acts as a buffer b/w Linux distributions & Win platform, buffer in the sense that it provides a universal channel for data transfers. I have constantly used this external hardisk for data transfers b/w win7 laptop & xubuntu (on this external hd) without any hassle. However, on of my desktops where I have ubuntu I (for the first time) attached this external drive which let me do data transfers where all three partitions properly mounted....but then nasty thing occurred the same that occurred before. I (as usual) tried booting via this external hd (one having xubuntu, one having being formerly used under Ubuntu) I got error Now I am totally devastated because similar thing happened ~6months before when I had fedora 17 in my external hd (instead of xubuntu) & after it was used under ubuntu the same happened...i didn't reported it because I already had planned towards debian instead of rpm! The mystery is that as long as I don't attach this external hd under ubuntu the data never** corrupts whereas under win xp/7 I can use it as a normal usb storage of coarse linux partitions aren’t available under win platforms... **From corrupts I mean hd fails to boot with the error mentioned however cant say whether data within remains untouched? It seems that my grub & or MBR is corrupted. Please sir guide me to solve this issue also why I cant attach & use linux external hds under linux platform Disk /dev/sdc: 160.0 GB, 160041884672 bytes 255 heads, 63 sectors/track, 19457 cylinders, total 312581806 sectors Units = sectors of 1 * 512 = 512 bytes Sector size (logical/physical): 512 bytes / 512 bytes I/O size (minimum/optimal): 512 bytes / 512 bytes Disk identifier: 0x0004e7d0 Device Boot Start End Blocks Id System /dev/sdc1 * 2048 976895 487424 83 Linux /dev/sdc2 978942 96874495 47947777 5 Extended /dev/sdc3 96874496 312575999 107850752 7 HPFS/NTFS/exFAT /dev/sdc5 978944 94726143 46873600 83 Linux /dev/sdc6 94728192 96874495 1073152 82 Linux swap / Solaris I can recall for sure that have seen a thread here when a similar problem occurred & in response someone gave solution of how to mount (now invisible) partitions & recover important data in them. I have misplaced that URL so if any can guide me thither because my important documents resides in / partition What I already have done: Without success I have tried this & related solutions What I plan to do: I believe that filesystem has corrupted & would you recommend solution like this provided I cant recall whether my /boot (500mb) partition was ext4 or ext2 though I am sure that my / (48gb) partition was ext4 UPDATE 1 Attached my external hd under Ubuntu ran followinf command as root grub-install /dev/sdc where /dev/sdc was my external hd containing corrupted xubuntu....it reported all done!

• Howto install acts_as_xapian on Ubuntu

  - by normalocity

  I've run into some great resources for installing "acts_as_xapian", and the supporting native libraries that are necessary to make it work. I've even got it to work well on my dev machine (OS X). However, I've followed the instructions on this site, and it doesn't work on my Ubuntu 9.10 (Karmic) production box. After successfully installing the "core" and "bindings" for xapian, the start of the mongrel server fails with the following: => Booting Mongrel => Rails 2.3.5 application starting on http://0.0.0.0:3000 acts_as_xapian: No Ruby bindings for Xapian installed /home/feelgoodtrader/.gem/ruby/1.8/gems/activesupport-2.3.5/lib/active_support/dependencies.rb:105:in `const_missing': uninitialized constant ActsAsXapian::Search::Xapian (NameError) from /var/lib/gems/1.8/gems/acts_as_xapian-0.1.3/lib/acts_as_xapian/search.rb:8 from /usr/lib/ruby/1.8/rubygems/custom_require.rb:31:in `gem_original_require' from /usr/lib/ruby/1.8/rubygems/custom_require.rb:31:in `require' from /home/feelgoodtrader/.gem/ruby/1.8/gems/activesupport-2.3.5/lib/active_support/dependencies.rb:156:in `require' from /home/feelgoodtrader/.gem/ruby/1.8/gems/activesupport-2.3.5/lib/active_support/dependencies.rb:521:in `new_constants_in' from /home/feelgoodtrader/.gem/ruby/1.8/gems/activesupport-2.3.5/lib/active_support/dependencies.rb:156:in `require' from /var/lib/gems/1.8/gems/acts_as_xapian-0.1.3/lib/acts_as_xapian.rb:2 from /var/lib/gems/1.8/gems/acts_as_xapian-0.1.3/lib/acts_as_xapian.rb:1:in `each' from /var/lib/gems/1.8/gems/acts_as_xapian-0.1.3/lib/acts_as_xapian.rb:1 from /usr/lib/ruby/1.8/rubygems/custom_require.rb:31:in `gem_original_require' from /usr/lib/ruby/1.8/rubygems/custom_require.rb:31:in `require' from /home/feelgoodtrader/.gem/ruby/1.8/gems/activesupport-2.3.5/lib/active_support/dependencies.rb:156:in `require' from /home/feelgoodtrader/.gem/ruby/1.8/gems/activesupport-2.3.5/lib/active_support/dependencies.rb:521:in `new_constants_in' from /home/feelgoodtrader/.gem/ruby/1.8/gems/activesupport-2.3.5/lib/active_support/dependencies.rb:156:in `require' from /home/feelgoodtrader/.gem/ruby/1.8/gems/rails-2.3.5/lib/rails/gem_dependency.rb:208:in `load' from /home/feelgoodtrader/.gem/ruby/1.8/gems/rails-2.3.5/lib/initializer.rb:307:in `load_gems' from /home/feelgoodtrader/.gem/ruby/1.8/gems/rails-2.3.5/lib/initializer.rb:307:in `each' from /home/feelgoodtrader/.gem/ruby/1.8/gems/rails-2.3.5/lib/initializer.rb:307:in `load_gems' from /home/feelgoodtrader/.gem/ruby/1.8/gems/rails-2.3.5/lib/initializer.rb:164:in `process' from /home/feelgoodtrader/.gem/ruby/1.8/gems/rails-2.3.5/lib/initializer.rb:113:in `send' from /home/feelgoodtrader/.gem/ruby/1.8/gems/rails-2.3.5/lib/initializer.rb:113:in `run' from /home/feelgoodtrader/feelgoodtrader/config/environment.rb:13 from /usr/lib/ruby/1.8/rubygems/custom_require.rb:31:in `gem_original_require' from /usr/lib/ruby/1.8/rubygems/custom_require.rb:31:in `require' from /home/feelgoodtrader/.gem/ruby/1.8/gems/activesupport-2.3.5/lib/active_support/dependencies.rb:156:in `require' from /home/feelgoodtrader/.gem/ruby/1.8/gems/activesupport-2.3.5/lib/active_support/dependencies.rb:521:in `new_constants_in' from /home/feelgoodtrader/.gem/ruby/1.8/gems/activesupport-2.3.5/lib/active_support/dependencies.rb:156:in `require' from /home/feelgoodtrader/.gem/ruby/1.8/gems/rails-2.3.5/lib/commands/server.rb:84 from /usr/lib/ruby/1.8/rubygems/custom_require.rb:31:in `gem_original_require' from /usr/lib/ruby/1.8/rubygems/custom_require.rb:31:in `require' from script/server:3

• Can any iSCSI NAS appliance replicate / clone a LUN to an external drive?

  - by Boden

  I would like to backup using Windows Imaging to some kind of NAS appliance. I believe this will require the NAS to support iSCSI. I would then like the appliance to support the replication of the iSCSI LUN to an external eSATA or USB disk connected directly to the appliance. I've found plenty of NAS appliances that can do iSCSI and replicate to an external drive, but none that I've found thus far can do both at once. That is, the devices can do iSCSI, but then the replication feature doesn't work. The idea here is to backup to an appliance located in a secure office far away from the server room. Offsite backups to external hard drive could be managed from the appliance. The benefits of such a setup would be: 1) very unlikely that fire or random theft would affect both server-room backup and "remote" backup appliance 2) offsite backups could be managed by multiple trusted people without granting access to server room 3) Windows imaging provides poor man's deduplication, so each backup volume can contain a decent backup history. I understand why this would be a non-trivial thing to implement, but I'm wondering if such a thing exists? Preferably a tabletop, low to medium cost device. Alternative solutions welcome. NOTE: I'm backing up very few but very large files, so file replication is not a good option.

• Is it possible to mount a disk image, created with dd, to a directory on a mounted external usb hdd?

  - by Keeper Hood

  I have an image of my home (/dev/sda3) partition, which I've created using the "dd" command. dd if=/dev/sda3 of=/path/to/disk.img I've deleted the home partition via gparted in order to enlarge my /dev/root partition. Then I've recreated the /dev/sda3 partition which is smaller in size then the one I've backed up to the image. I was wondering since I have a 2TB external HDD, could it be possible to mount my backed up image on the external HDD and then copy the files into the /home directory. Since the external HDD would be already in a "mounted state", I'm unsure whether this is a good idea, mounting on a mounted device. I'm running Slackware 13.37 (64bit). used ext4 on all the partitions. resized the root partition with gparted live cd. I've tried mount -t ext4 /path/to/disk.img /mng/image -o loop It gave me an fs error (wrong fs type, bad option, bad superblock on dev/loop/0) Then i did dmesg | tail which outputs: EXT4-fs (loop0) : bad geometry: block count 29009610 exceeds size of defice (1679229 blocks) I have no idea what to do, I want to restore my /home data from the image I've backed up.

I would then like the appliance to support the replication of the iSCSI LUN to an external eSATA or USB disk connected directly to the appliance. I've found plenty of NAS appliances that can do iSCSI and replicate to an external drive, but none that I've found thus far can do both at once. That is, the devices can do iSCSI, but then the replication feature doesn't work. The idea here is to backup to an appliance located in a secure office far away from the server room. Offsite backups to external hard drive could be managed from the appliance. The benefits of such a setup would be: 1) very unlikely that fire or random theft would affect both server-room backup and "remote" backup appliance 2) offsite backups could be managed by multiple trusted people without granting access to server room 3) Windows imaging provides poor man's deduplication, so each backup volume can contain a decent backup history. I understand why this would be a non-trivial thing to implement, but I'm wondering if such a thing exists? Preferably a tabletop, low to medium cost device. Alternative solutions welcome. NOTE: I'm backing up very few but very large files, so file replication is not a good option.

• Am I able to forward traffic from an external subdomain to a specific local host?

  - by George Bowman

  I apologise in advance if the question doesn't make sense, please let me know. I've got a small LAN (~10 Virtual Servers) using Win Server 2008 as a DNS server. This is behind a smoothwall express 3.0 firewall with ports forwarded for specific services. I have a domain (123-reg) with the NS's that of afraid.org (DynamicDNS) and subdomains pointed to my (Dynamic) IP address e.g. subdomain1.example.com - 123.456.789.101. I think that adequately explains my set up. My question is, am I able to have subdomains e.g. subdomain1.example.com only point to a specific local host? Like so: subdomain1.example.com:80 - firewall(external facing) - server1.example.com:80 subdomain2.example.com:80 - firewall(external facing) - server2.example.com:80 I don't actually necessarily want to use port 80, otherwise I would just use VirtualHosts on apache, it is just an example port. Currently I can use either subdomain1.example.com OR subdomain2.example.com and they will both point to server1.example.com:80 I do not have to stay using Win Server 2008 for DNS, I am more than happy to move over to BIND if needs be, it was just easier to use Win Server 2008's DNS. I do not know if this is even possible, I have a feeling it isn't as I've only got one external IP address but any information is useful!

• How can I pass an external instance to the constructor of an object that's being created using the default XNA XML content loader?

  - by Michael

  I'm trying to understand how to use the XNA XML content importer to instantiate non-trivial objects that are more than a collection of basic properties (e.g., a class that inherits from DrawableGameObject or GameObject and requires other things to be passed into its constructor). Is it possible to pass existing external instances (e.g., an instance of the current Game) to the constructor of an object that's being created using the default XNA XML content loader? For example, imagine that I have the following class, inheriting from DrawableGameComponent: public class Character : DrawableGameComponent { public string Name { get; set; } public Character(Game game) : base(game) { } public override void Update(GameTime gameTime) { } public override void Draw(GameTime gameTime) { } } If I had a simple class that did not need other parameters in its constructor (i.e., the Game instance), then I could simply use this XML: <XnaContent> <Asset Type="MyNamespace.Character"> <Name>John Doe</Name> </Asset> </XnaContent> ...and then create an instance of Character using this code: var character = Content.Load<Character>("MyXmlAssetName"); But that won't work because I need to pass the need to pass the Game into the constructor. What's the best way to handle this situation? Is there a way to pass in things like the current Game using the default XNA XML content loader? Do I need to write my own XML loader? (If so, how?) Is there a better object-oriented design that I should be using for my classes? Note: Although I used Game in this example, I'm really just asking how to pass any type of existing instance to my constructors. (For example, I'm using the Farseer Physics Engine, and some of my classes also need a reference to the Farseer World object too.) Thanks in advance.

• How should a JEE application store credentials for logging in to an external system?

  - by FGreg

  I am in a situation where I have a Web Application (WAR) that is accessing a REST service provided by another application. The REST service uses Basic HTTP Authentication. So that means the application calling the REST service needs to store user credentials somehow. To further complicate things, this is an enterprise, so there are different 'regions' the application moves through which will have different credentials for the same service (think local development, development region, integration region, user test region, production, etc...) My first instinct is that the credentials should be stored by the JEE container and the application should ask the container for the credentials (probably via JNDI?). I'm beginning to read about Java Authentication and Authorization Service (JAAS) but I'm not sure if that is the appropriate solution to this problem. How should a JEE application store credentials for logging in to an external system? A few more details about my WAR. It is a Spring-Integration project that has no front-end. The container I am working with is Websphere. I am using JEE 5 and Spring 4.0.1. To this point I have not needed to consider spring-security... does this situation mean I should re-evaluate that decision?

• How do I 'see' an external USB drive connected directly to my Broadband Router?

  - by The Cougar Kid

  This is a very frustrating problem! I have a small home network with several dual boot Ubuntu / Windows computers. I have recently upgraded my Broadband connection and the new router permits the direct attachment of an external USB drive which can back up all of the household's computers. There are no problems when booted under Windows, and there were no problems with older versions of UBUNTU, but since upgrading to 11.10 I can no longer "see" the drive. I used to find it via Network / Windows Network / Home / name of Router, but under 11.10 the same method yields an error message Unable to mount location Failed to retrieve share list from server. Can anyone help please?

• Is full partition encryption the only sure way to make Ubuntu safe from external access?

  - by fred.bear

  (By "external access", I mean eg. via a Live CD, or another OS on the same dual-boot machine) A friend wants to try Ubuntu. He's fed up with Vista grinding to a crawl (the kids? :), so he likes the "potential" security offered by Ubuntu, but because the computer will be multi-booting Ubuntu (primary) and 2 Vistas (one for him, if he ever needs it again, and the other one for the kids to screw up (again). However, he is concerned about any non-Ubuntu access to the Ubuntu partitions (and also to his Vista partition)... I believe TrueCrypt will do the job for his Vista, but I'd like to know what the best encryption system for Ubuntu is... If TrueCrypt works for Ubuntu, it may be the best option for him, as it would be the same look and feel for both. Ubuntu will be installed with 3 partitions; 1) root 2) home 3) swap.. Will Ubuntu's boot loader clash with TrueCrypt's encrypted partition? PS.. Is encryption a suitable solution?

• How do I fix the python installer's 'missing dependencies' error?

  - by Trevor Boyd Smith

  Background: running ubuntu So I downloaded the python "install from source" tarball. I ran make and got this error message: Python build finished, but the necessary bits to build these modules were not found: _aaa _bbb _ccc ... _jjj _kkk I google'd and found one solution is to: MANUALLY map all the string names from the error message to something in the apt-get repo MANUALLY call "sudo apt-get AAA BBB ... JJJ KKK" to get all the libraries I can easily do all of that. But I have no way of knowing what is the right version libraries I need to get! How in the world am I supposed to fix the missing dependencies if I don't know what the exact missing dependency is?

• Java code to convert a list of dependencies into a build order?

  - by Egon Willighagen

  Given I have a list of dependencies, like: module1 module2 dependsOn module1 module3 dependsOn module1 module4 dependsOn module3 I would like to create a build order where each build step is found on one line, and each line contains a list of one or more modules which can be compiled at the same time, and which only depend on modules compiled earlier. So, for the above data set, create a list like: module1 module2,module3 module4 Now, this is basically just a problem of creating a directed graph, and analyzing it. Now, I am using Ant, and would very much like to use something off-the-shelf... what is the minimum of custom code I need to have it create such a dependency-aware build list starting from the given input? BTW, these modules are actually custom modules, so maven will not work.

• Circular dependencies in StructureMap - can they be broken with property injection?

  - by Andy

  Hi, I've got the simplest kind of circular dependency in structuremap - class A relies on class B in its constructor, and class B relies on class A in its constructor. To break the dependency, I made class B take class A as a property, rather than a constructor argument, but structuremap still complains. I've seen circular dependencies broken using this method in other DI frameworks - is this a problem with Structuremap or am I doing something wrong? Edit: I should mention that class B's property is an array of class A instances, wired up like this: x.For<IB>().Singleton().Use<B>().Setter(y => y.ArrayOfA).IsTheDefault();

• How can I force maven to use my mock version of dependencies during the test phase.

  - by Jayd16

  Hi, so I have a Java application with a that accesses some web services. I want to mock out the appropriate classes so I can just use a few hard coded request/responses and I want maven to seamlessly use them during the tests and ignore them during the final build. I want maven2 to: 1)compile my mock classes 2)compile the main classes that depend on the mocked code 3)run tests 4)recompile any main classes with the real dependencies, not my mocks 5)finish up the maven install Ideally I want to just name my mock classes the same as my main class and just keep them in src/test/mocks or something. I'm kind of new to maven and so far it looks like maven will only compile the src/main and then src/test but I'm hoping I can have my way. Any ideas?
