• Bluetooth headset A2DP works, HSP/HFP not (no sound/no mic)

  - by Stefan Armbruster

  My Philips SBH9001 headset pairs fine using Ubuntu 12.04. In the audio settings it's properly detected as A2DP device and as HSP/HFP device. Hardware: Thinkpad X230, Ubuntu 12.04 64bit, Kernel 3.6.0-030600rc3-generic (build from Ubuntu mainline repo), Bluetooth device is USB-Id 0a5c:21e6 from Broadcom, Headset is a Philips SBH9001. Note: Kernel 3.6 rc3 is used because of a fix for audio on the dockingstation that is not in any previous branches. Playing audio in A2DP works just fine out of the box, but when switching the headset to HSP/HSP mode there is no sound nor does the microphone work. When connecting the headset, /var/log/syslog shows: Aug 25 21:32:47 x230 bluetoothd[735]: Badly formated or unrecognized command: AT+CSRSF=1,1,1,1,1,7 Aug 25 21:32:49 x230 rtkit-daemon[1879]: Successfully made thread 17091 of process 14713 (n/a) owned by '1000' RT at priority 5.

• Dot Matrix printers setup...

  - by Parhs

  Hello! I am using debian which is similar to ubuntu. They have 7 dot matrix printers some very old like this one http://www.omnidatasys.net/product/desc_printer_ti880.htm which works from 1979 daily and at text is faster than many inkjects. I believe that it has his own language... Sending text to serial port (port server) prints garbage. However i think is prints only capital english up to 95 asccii and greek and the rest up to 127 i think greek capital.(special chip ) Sending english capital letters prints garbage i think but i amnt sure... i will try again... The other printer are ESC/P compatible and i use generic epson driver provided from ghostscript... However i think that sending text via lp -dpr1 filename It prints the text as a grafic...Changing from printer font face(courier,times roman etc) or pitch has no effect... I am wondering if is there any work arround for this? In AIX they claim that lp command printed output as text as it prints and cobol programs send raw text to to lp printers . However in AIX they use some custom filters for the printers and has more options for dot matrix printers.. I would like to know if there is a solution for this.. To avoid graphics mode for text and change font face somehow.. The most Straight-through approach would be to use no driver ,just send ESC/P from cobol but this requires too much work... Thank you again!

• responsibility for storage

  - by Stefano Borini

  A colleague and I were brainstorming about where to put the responsibility of an object to store itself on the disk in our own file format. There are basically two choices: object.store(file) fileformatWriter.store(object) The first one gives the responsibility of serialization on the disk to the object itself. This is similar to the approach used by python pickle. The second groups the representation responsibility on a file format writer object. The data object is just a plain data container (eventually with additional methods not relevant for storage). We agreed on the second methodology, because it centralizes the writing logic from generic data. We also have cases of objects implementing complex logic that need to store info while the logic is in progress. For these cases, the fileformatwriter object can be passed and used as a delegate, calling storage operations on it. With the first pattern, the complex logic object would instead accept the raw file, and implement the writing logic itself. The first method, however, has the advantage that the object knows how to write and read itself from any file containing it, which may also be convenient. I would like to hear your opinion before starting a rather complex refactoring.

• About to smash my keyboard!! Ubuntu 13.1 issues with AMD driver & Audio

  - by DNex

  Let me preface with saying that this is my 2nd day on Linux. I really want to make it work but these issues are driving me up the wall! I've done exhaustive google searches but have not been able to figure anything out. I am on Ubuntu 13.10, my graphics card is AMD Radeon HD4200. My sound card is a realtek HDMI. I've tried downloading and installing both drivers but nothing works. Graphics card: When I run the .run file (from http://www2.ati.com/drivers/legacy/amd-driver-installer-catalyst-13.1-legacy-linux-x86.x86_64.zip) I get an error. I check the fglrx-install log and it says this: Check if system has the tools required for installation. fglrx installation requires that the system have kernel headers. /lib/modules/3.11.0-12-generic/build/include/linux/version.h cannot be found on this system. One or more tools required for installation cannot be found on the system. Install the required tools before installing the fglrx driver. Optionally, run the installer with --force option to install without the tools. Forcing install will disable AMD hardware acceleration and may make your system unstable. Not recommended. Audio: Since my first install I've had no audio. I've tried everything outlined in this site: http://itsfoss.com/fix-sound-ubuntu-1304-quick-tip/ to no avail. I've download the linux drivers from Realtek HDMI audio but have had no luck. Any help would be extremely appreciated.

• 12.04 No Sound - ALC888 / Radeon 3200HD

  - by Ross

  Evening all. I have a MSI U230 netbook, MV40 processor, 4Gb RAM with integrated ATI Radeon 3200HD grahics & an ALC888 codec integrated soundcard. It has HDMI out as well. I've tried a few distro's and have been around linux for a short time. I reckon I've settled on Ubuntu 12.04 (32bit) due to it doing pretty much everything I want it to. I'm working with a fresh install right now. I recently re-installed when I was going in circles trying to solve my problem before. I install Ubuntu and it works, except for the sound. I have tried things like reinstalling Alsa, editing my asound.conf file, installing HDA Verb and a few other things. Its at the point where I need to ask for help... Some outputs: ross@ross:~$ aplay -l ** List of PLAYBACK Hardware Devices ** card 0: SB [HDA ATI SB], device 0: ALC888 Analog [ALC888 Analog] Subdevices: 1/1 Subdevice #0: subdevice #0 card 1: HDMI [HDA ATI HDMI], device 3: HDMI 0 [HDMI 0] Subdevices: 1/1 Subdevice #0: subdevice #0 ross@ross:~$ uname -r 3.2.0-34-generic-pae ross@ross:~$ lspci | grep VGA 01:05.0 VGA compatible controller: Advanced Micro Devices [AMD] nee ATI RS780M/RS780MN [Mobility Radeon HD 3200 Graphics] ross@ross:~$ lspci | grep Audio 00:14.2 Audio device: Advanced Micro Devices [AMD] nee ATI SBx00 Azalia (Intel HDA) 01:05.1 Audio device: Advanced Micro Devices [AMD] nee ATI RS780 HDMI Audio [Radeon HD 3000-3300 Series] Added options snd-hda-intel position_fix=1 to alsa-base.conf file Unmuted all in alsamixer Can anyone suggest anything more?

• Wammu - USB Device Name?

  - by Paul

  I'm trying to get to my phone's filesystem through USB in Wammu, but I'm stuck in the configuration wizard when it asks for a USB device name. After about an hour of Internet searching, here are the failed solutions I've already tried, starting with the relevant information returned by lsusb in terminal. lsusb Bus 001 Device 003: ID 12d1:101e Huawei Technologies Co., Ltd. So I tried opening Wammu through sudo wammu in terminal and inputting "/dev/bus/usb/001/003" as the device name, which returns: Error opening device Device /dev/bus/usb/001/003 does not exist! and then "/dev/bus/usb/001/", which returns: Failed to connect to phone Description: Error opening device. Unknown, busy, or no permissions.<br> Function: Init<br> Error code: 2 Another proposed solution was to try "tail -f /var/log/messages" in terminal. But that only returned a "No such file or directory" message. Seemingly relevant dmesg info: [ 4739.716214] usb 1-1: new high-speed USB device number 8 using ehci_hcd [ 4739.854137] scsi9 : usb-storage 1-1:1.0 [ 4740.854416] scsi 9:0:0:0: CD-ROM HUAWEI T Mass Storage 2.31 PQ: 0 ANSI: 2 [ 4740.867051] sr0: scsi-1 drive [ 4740.867806] sr 9:0:0:0: Attached scsi CD-ROM sr0 [ 4740.870464] sr 9:0:0:0: Attached scsi generic sg1 type 5 I don't know why it is coming up as CD-ROM. But there it is. If you haven't noticed already, I'm an absolute beginner when it comes to Linux and terminal. So speaking to me like I'm a three year old is welcome if you can propose a solution. I'm running Ubuntu 12.04 LTS, and the phone is a Huawei U1250. My computer is an Acer Aspire One D250/KAV60. Any help is much appreciated.

• Cinnamon Settings Panel Blank After v 2.0.6

  - by Cinnamon Challenge

  After cinnamon upgrade to 2.0.6-20131026040307-precise via synaptic, the "cinnamon settings" gui or window is broken. It appears blank, only showing the configuration category icons for "Appearance", "Preferences", "Hardware", and "Administration". The icons that should be within these categories are gone. I don't know if cinnamon-control-center was removed during the last cinnamon update, but this issue began on Oct. 25.

• Organising data access for dependency injection

  - by IanAWP

  In our company we have a relatively long history of database backed applications, but have only just begun experimenting with dependency injection. I am looking for advice about how to convert our existing data access pattern into one more suited for dependency injection. Some specific questions: Do you create one access object per table (Given that a table represents an entity collection)? One interface per table? All of these would need the low level Data Access object to be injected, right? What about if there are dozens of tables, wouldn't that make the composition root into a nightmare? Would you instead have a single interface that defines things like GetCustomer(), GetOrder(), etc? If I took the example of EntityFramework, then I would have one Container that exposes an object for each table, but that container doesn't conform to any interface itself, so doesn't seem like it's compatible with DI. What we do now, in case it helps: The way we normally manage data access is through a generic data layer which exposes CRUD/Transaction capabilities and has provider specific subclasses which handle the creation of IDbConnection, IDbCommand, etc. Actual table access uses Table classes that perform the CRUD operations associated with a particular table and accept/return domain objects that the rest of the system deals with. These table classes expose only static methods, and utilise a static DataAccess singleton instantiated from a config file.

• What is a Data Warehouse?

  Typically Data Warehouses are considered to be non-volatile in comparison to traditional databasesdue to the fact that data within the warehouse does not change that often.  In addition, Data Warehouses typically represent data through the use of Multidimensional Conceptual Views that allow data to be extracted based on the view and the current position within the view. Common Data Warehouse Traits Relatively Non-volatile Data Supports Data Extraction and Analysis Optimized for Data Retrieval and Analysis Multidimensional Views of Data Flexible Reporting Multi User Support Generic Dimensionality Transparent Accessible Unlimited Dimensions of Data Unlimited Aggregation levels of Data Normally, Data Warehouses are much larger then there traditional database counterparts due to the fact that they store the basis data along with derived data via Multidimensional Conceptual Views. As companies store larger and larger amounts of data, they will need a way to effectively and accurately extract analysis information that can be used to aide in formulating current and future business decisions. This process can be done currently through data mining within a Data Warehouse. Data Warehouses provide access to data derived through complex analysis, knowledge discovery and decision making. Secondly, they support the demands for high performance in regards to analyzing an organization’s existing and current data. Data Warehouses provide support for an organization’s data and acquired business knowledge.  Within a Data Warehouse multiple types of operations/sub systems are supported. Common Data Warehouse Sub Systems Online Analytical Processing (OLAP) Decision –Support Systems (DSS) Online Transaction Processing (OLTP)

• OOP concept: is it possible to update the class of an instantiated object?

  - by Federico

  I am trying to write a simple program that should allow a user to save and display sets of heterogeneous, but somehow related data. For clarity sake, I will use a representative example of vehicles. The program flow is like this: The program creates a Garage object, which is basically a class that can contain a list of vehicles objects Then the users creates Vehicles objects, these Vehicles each have a property, lets say License Plate Nr. Once created, the Vehicle object get added to a list within the Garage object --Later on--, the user can specify that a given Vehicle object is in fact a Car object or a Truck object (thus giving access to some specific attributes such as Number of seats for the Car, or Cargo weight for the truck) At first sight, this might look like an OOP textbook question involving a base class and inheritance, but the problem is more subtle because at the object creation time (and until the user decides to give more info), the computer doesn't know the exact Vehicle type. Hence my question: how would you proceed to implement this program flow? Is OOP the way to go? Just to give an initial answer, here is what I've came up until now. There is only one Vehicle class and the various properties/values are handled by the main program (not the class) through a dictionary. However, I'm pretty sure that there must be a more elegant solution (I'm developing using VB.net): Public Class Garage Public GarageAdress As String Private _ListGarageVehicles As New List(Of Vehicles) Public Sub AddVehicle(Vehicle As Vehicles) _ListGarageVehicles.Add(Vehicle) End Sub End Class Public Class Vehicles Public LicensePlateNumber As String Public Enum VehicleTypes Generic = 0 Car = 1 Truck = 2 End Enum Public VehicleType As VehicleTypes Public DictVehicleProperties As New Dictionary(Of String, String) End Class NOTE that in the example above the public/private modifiers do not necessarily reflect the original code

• 12.04 kernel panic

  - by jesus

  Hello I'm having trouble with Ubuntu 12.04. I downloaded the ISO and burned it into a CD and tried to install Ubuntu, but during the installation process, I got this message Kernel panic-not syncing Attempted to kill init! pid:1,comm:init not tainted 3.2.0-23-generic-pae#36-ubunru then it says switching to console text, and it just hangs in there and nothing happens. I burned another CD with Ubuntu 10.04, but I get a different problem: Ubuntu just gets stuck at the splash screen with the 5 dots which move from red to white, and nothing happens. I was able to boot before with 10.04 but I recently upgraded my computer graphics card and power supply. please see my system specs.

• How to limit click'n'drag movement to an area?

  - by Vexille

  I apologize for the somewhat generic title. I'm really don't have much clue about how to accomplish what I'm trying to do, which is making it harder even to research a possible solution. I'm trying to implement a path marker of sorts (maybe there's a most suitable name for it, but this is the best I could come up with). In front of the player there will be a path marker, which will determine how the player will move once he finishes planning his turn. The player may click and drag the marker to the position they choose, but the marker can only be moved within a defined working area (the gray bit). So I'm now stuck with two problems: First of all, how exactly should I define that workable area? I can imagine maybe two vectors that have the player as a starting point to form the workable angle, and maybe those two arcs could come from circles that have their center where the player is, but I definetly don't know how to put this all together. And secondly, after I've defined the area where the marker can be placed, how can I enforce that the marker should only stay within that area? For example, if the player clicks and drags the marker around, it may move freely within the working area, but must not leave the boundaries of the area. So for example, if the player starts dragging the marker upwards, it will move upwards until it hits he end of the working area (first diagram below), but if after that the player starts dragging sideways, the marker must follow the drag while still within the area (second diagram below). I hope this wasn't all too confusing. Thanks, guys.

• ORA-600 Troubleshooting

  - by [email protected]

  Have you observed an ORA-0600 or ORA-07445 reported in your alert log? The ORA-600 error is the generic internal error number for Oracle program exceptions. It indicates that a process has encountered a low-level, unexpected condition. The ORA-600 error statement includes a list of arguments in square brackets: ORA 600 "internal error code, arguments: [%s], [%s],[%s], [%s], [%s]" The first argument is the internal message number or character string. This argument and the database version number are critical in identifying the root cause and the potential impact to your system.  The remaining arguments in the ORA-600 error text are used to supply further information (e.g. values of internal variables etc).   Looking for the best way to diagnose? There is an ORA-600 Troubleshooter Tool available in My Oracle Support.  This tool will lead you to applicable content in My Oracle Support on the problem and can be used to investigate the problem with argument data from the error message or you can pull out the first 10 or 15 stack pointers from the associated trace file to match up against known bugs. Note 153788.1 ORA-600/ORA-7445 TroubleshooterNote 1082674.1 A Video To Demonstrate The Usage Of The ORA-600/ORA-7445 Lookup Tool [Video] Also, take a quick look at the Master Note for Diagnosing ORA-600 ( MasterNoteORA600.docx) for some tips on diagnosing.

• Merge two different API calls into One

  - by dhilipsiva

  I have two different apps in my django project. One is "comment" and an other one is "files". A comment might save some file attached to it. The current way of creating a comment with attachments is by making two API calls. First one creates an actual comment and replies with the comment ID which serves as foreign key for the Files. Then for each file, a new request is made with the comment ID. Please note that file is a generic app, that can be used with other apps too. What is the cleanest way of making this into one API call? I want to have this as a single API call because I am in a situation where I need to send user an email with all the files as attachment when a comment is made. I know Queueing is the ideal way to do it. But I don't have the liberty to add queing to our stack now. So this was the only way I could think of.

• How to use the Raring/Saucy netboot installer to install Precise?

  - by mikepurvis

  We have a Haswell motherboard with onboard ethernet controllers which are not supported in the Precise (3.2) kernel. However, we're using netboot installation, and we'd really like to stick with the LTS version. Once the Precise install is completed, we can install the linux-generic-lts-saucy package, which gets us the ethernet hardware support which is ultimately required. So, our options are: Plug in a USB-Ethernet (or even wifi) dongle, perform the install that way. Modify the Precise installer to somehow include the required driver (a udeb, or some early_command invocation?) Modify the Raring installer (3.8 kernel, which supports the device) to instead install Precise. If it's possible the third option seems like the simplest and most logical to me. Now, we are already using the precise-updates installer (Aug 2013), as opposed to the original April 2012 installer. However, the precise-updates installer still appears to use the 3.2 kernel. I'm already comfortable with preseeding and modifying the netboot initrd. So my question is, can I somehow modify the Raring/Saucy netboot initrd to instead install Precise? Thanks.

EDIT 2: After a long break from this problem, I've just run a few tests again and found out that, although my macbuntu still fails to connect to my home wi-fi network, it works just fine at my university... Does that help in anyway? My home network is managed by a dual-band (2.4Ghz and 5Ghz) 802.11n cisco e4200 wi-fi router.

• How to use batch rendering with an entity component system?

  - by Kiril

  I have an entity component system and a 2D rendering engine. Because I have a lot of repeating sprites (the entities are non-animated, the background is tile based) I would really like to use batch rendering to reduce calls to the drawing routine. What would be the best way to integrate this with an engtity system? I thought about creating and populating the sprite batche every frame update, but that will probably be very slow. A better way would be to add a reference to an entity's quad to the sprite batch at initialization, but that would mean that the entity factory has to be aware of the Rendering System or that the sprite batch has to be a component of some Cache entity. One case violates encapsulation pretty heavily, while the other forces a non-game object entity in the entity system, which I am not sure I like a lot. As for engine, I am using Love2D (Love2D website) and FEZ ( FEZ website) as entity system(so everything is in Lua). I am more interested in a generic pattern of how to properly implement that rather than a language/library specific solution. Thanks in advance!

• Is your TRY worth catching?

  - by Maria Zakourdaev

    A very useful error handling TRY/CATCH construct is widely used to catch all execution errors  that do not close the database connection. The biggest downside is that in the case of multiple errors the TRY/CATCH mechanism will only catch the last error. An example of this can be seen during a standard restore operation. In this example I attempt to perform a restore from a file that no longer exists. Two errors are being fired: 3201 and 3013: Assuming that we are using the TRY and CATCH construct, the ERROR_MESSAGE() function will catch the last message only: To workaround this problem you can prepare a temporary table that will receive the statement output. Execute the statement inside the xp_cmdshell stored procedure, connect back to the SQL Server using the command line utility sqlcmd and redirect it's output into the previously created temp table.  After receiving the output, you will need to parse it to understand whether the statement has finished successfully or failed. It’s quite easy to accomplish as long as you know which statement was executed. In the case of generic executions you can query the output table and search for words like“Msg%Level%State%” that are usually a part of the error message.Furthermore, you don’t need TRY/CATCH in the above workaround, since the xp_cmdshell procedure always finishes successfully and you can decide whether to fire the RAISERROR statement or not. Yours, Maria
