• Using Computer Management (MMC) with the Solaris CIFS Service (August 25, 2009)

  - by user12612012

  One of our goals for the Solaris CIFS Service is to provide seamless Windows interoperability: not just to deliver ubiquitous, multi-protocol file sharing, which is obviously a major part of this project, but to support Windows services at a fundamental level.  It's an ongoing mission and our latest update includes support for Windows remote management. Remote management is extremely important to Windows administrators and one of the mainstay tools is Computer Management. Computer Management is a Windows administration application, actually a collection of Microsoft Management Console (MMC) tools, that can be used to configure, monitor and manage local and remote services and resources.  The MMC is an extensible framework of registered components, known as snap-ins, which allows Computer Management to provide comprehensive management features for both the local system and remote systems on the network. Supported Computer Management features include: Share ManagementSupport for share management is relatively complete.  You can create, delete, list and configure shares.  It's not yet possible to change the maximum allowed or number of users properties but other properties, including the Share Permissions, can be managed via the MMC. Users, Groups and ConnectionsYou can view local SMB users and groups, monitor user connections and see the list of open files. If necessary, you can also disconnect users and/or close files. ServicesYou can view the SMF services running on an OpenSolaris system.  This is a read-only view - we don't support service management (the ability to start or stop) SMF services from Computer Management (yet). To ensure that only the appropriate users have access to administrative operations there are some access restrictions on these remote management features. Regular users can: List shares Only members of the Administrators or Power Users groups can: Manage shares List connections Only members of the Administrators group can: List open files and close files Disconnect users View SMF services View the EventLog Here's a screenshot when I was using Computer Management and Server Manager (another Windows remote management application) on Windows XP to view some open files on an OpenSolaris system to prepare a slide presentation on MMC support.

• CUDA & MSI GT60 with Optimus enabled GTX670M?

  - by user1076693

  I have a MSI GT60 Laptop with an Optimus enabled GTX 670M GPU, and I have been trying to get CUDA going in Ubuntu 12.04 environment. I realize that Optimus is not supported in Linux, but I have read the following post suggesting that CUDA works for hybrid GPUs. How can I get nVidia CUDA or OpenCL working on a laptop with nVidia discrete card/Intel Integrated Graphics? I installed the NVIDIA driver via sudo add-apt-repository ppa:ubuntu-x-swat/x-updates sudo apt-get update sudo apt-get install nvidia-current The resulting driver version is 302.17, and supposedly GTX 670M is supported since 295.59. I also downloaded CUDA 4.2 from the NVIDIA site, and compiled it against nvidia-current libraries. Unfortunately, when I run deviceQuery in the CUDA SDK, I get the following output cudaGetDeviceCount returned 38 -> no CUDA-capable device is detected Checking /proc/driver/nvidia/gpus/0/information gives the following Model: GeForce GTX 670M IRQ: 16 GPU UUID: GPU-????????-????-????-????-???????????? Video BIOS: ??.??.??.??.?? Bus Type: PCI-E DMA Size: 32 bits DMA Mask: 0xffffffffff Bus Location: 0000:01.00.0 Here is the output of "lspci | grep VGA" 00:02.0 VGA compatible controller: Intel Corporation Ivy Bridge Graphics Controller (rev 09) 01:00.0 VGA compatible controller: NVIDIA Corporation Device 1213 (rev ff) So... what am I doing wrong? Thanks!

• Naming a class that processes orders

  - by p.campbell

  I'm in the midst of refactoring a project. I've recently read Clean Code, and want to heed some of the advice within, with particular interest in Single Responsibility Principle (SRP). Currently, there's a class called OrderProcessor in the context of a manufacturing product order system. This class is currently performs the following routine every n minutes: check database for newly submitted + unprocessed orders (via a Data Layer class already, phew!) gather all the details of the orders mark them as in-process iterate through each to: perform some integrity checking call a web service on a 3rd party system to place the order check status return value of the web service for success/fail email somebody if web service returns fail constantly log to a text file on each operation or possible fail point I've started by breaking out this class into new classes like: OrderService - poor name. This is the one that wakes up every n minutes OrderGatherer - calls the DL to get the order from the database OrderIterator (? seems too forced or poorly named) - OrderPlacer - calls web service to place the order EmailSender Logger I'm struggling to find good names for each class, and implementing SRP in a reasonable way. How could this class be separated into new class with discrete responsibilities?

• Why do I need a framework?

  - by lvictorino

  First of all I know my question may sounds idiot but I am no "beginner". In fact I work as game developer for several years now and I know some things about code :) But as this is no related to game development I am a bit lost. I am writing a big script (something about GIS) in Python, using a lot of data stored in a database. I made a first version of my script, and now, I'd like to re-design the whole thing. I read some advice about using a framework (like Django) for database queries. But as my script only "SELECT" informations I was wondering about the real benefits to use a framework. It seems that it adds a lot of complexity and useless embedded features (useless for my specific script) for the benefits that it will bring. Am I wrong? EDIT: few spec of this "script". Its purpose is to get GIS data on an enormous database (if you ever worked with openstreetmap you know what I mean ~= 200Go) and to manipulate this data in order to produce nice map images. Queries are not numerous (select streets, select avenues, select waterways, select forests... and so on for a specific area) but query results may be more than 10.000 rows. I'd like to sell this script as a service, so yes it's meant to stay.

• Frame Independent Movement

  - by ShrimpCrackers

  I've read two other threads here on movement: Time based movement Vs Frame rate based movement?, and Fixed time step vs Variable time step but I think I'm lacking a basic understanding of frame independent movement because I don't understand what either of those threads are talking about. I'm following along with lazyfoo's SDL tutorials and came upon the frame independent lesson. http://lazyfoo.net/SDL_tutorials/lesson32/index.php I'm not sure what the movement part of the code is trying to say but I think it's this (please correct me if I'm wrong): In order to have frame independent movement, we need to find out how far an object (ex. sprite) moves within a certain time frame, for example 1 second. If the dot moves at 200 pixels per second, then I need to calculate how much it moves within that second by multiplying 200 pps by 1/1000 of a second. Is that right? The lesson says: "velocity in pixels per second * time since last frame in seconds. So if the program runs at 200 frames per second: 200 pps * 1/200 seconds = 1 pixel" But...I thought we were multiplying 200 pps by 1/1000th of a second. What is this business with frames per second? I'd appreciate if someone could give me a little bit more detailed explanation as to how frame independent movement works. Thank you.

• Precise: Evolution laggy due to IMAP -profile or due to some odd Sync -issue?

  - by Izzy

  I'm fighting with Evolution. Basically it's working fine -- but it is very slow to react in certain situations. There is apparently some problem with syncing and IMAP. Helper questios Could be that changing away from Bonobo has to do with slowing-down? There might be some trouble with the new engine and "asynchronous actions". What to do about it? I want to get the previous "working mood" back. How can I speed this thing up? Different scenarios when sending a mail, the composer window hangs there inactive for a couple of seconds, everything grayed out. Though there is a green check mark saying it's sent, I'm not sure a) why it's still blocking everything and b) whether I could simply close it without "breaking"/"losing" anything. In earlier versions, the composer window was closing pretty fast, and one could see the message being stored into the local "outbox" until it was sent, and one could immediately continue with the next task. I prefer that behaviour over the current. switching between modules. Coming from mail and switching to the address book takes a couple of seconds. Same for switching to the calendar. I read about different "possible causes" and tried a few things: I only have 3 local address books, so no networking should be involved here. To make sure, I switched to offline mode and then tried to access the address book. No noticeable difference. I use 3 Google Calendars. Switching to offline mode made a minor difference, but so minor that it also could be "imagination" since one might have expected this in this case according to some reports, disabling the tasks should help. Well, it didn't in my case, as I don't use them regularly (just two local items stored here)

• We are moving an Access based corporate front-end into a Web-based App

  - by Max Vernon

  We have an enterprise application with a front end written in Microsoft Access 2003 that has evolved over the past 6 years. The back end data, and a fair amount of back-end logic is contained within several Microsoft SQL Server databases. This front end app consists of around 180 forms, and over 120,000 lines of code, and interacts with VB.Net DLLs that support various critical functions used by our sales force. The current system makes use of 3 monitors to display various information; the Access app uses COM+ to control Microsoft Outlook and Internet Explorer for various purposes. The Access front end sometimes occupies 2 screens, automatically resizing itself based on Windows API-reported screen dimensions. The app also uses a Google map to present data to our agents, and allows two-way interactivity with the map through COM+ connectivity to JavaScript contained in the Google map. At the urging of senior management, we are looking to completely rewrite this application using some web-based technology, such as ASP.Net or perhaps a LAMP stack (the thinking with the LAMP stack thing is "free" is pretty cheap). We want to move to a web-based app so we can eliminate the dependency on our physical location for hiring new sales force members. Currently, our main office is full to capacity, and we need to continue growing the company. Does anyone have any thoughts on what would be the best technology to use for a web-based app of this magnitude? Keeping in mind the app is dependent on back-end services on our existing infrastructure. The app handles financial data and personal customer data, among other things. [I've looked at Best practices for moving large MS Access application towards .Net? and read the answers, and most of the comments. Interesting reading, and has some valid points, but our C.O.O. and contracted Software Architect are pushing for a full web-based app, not a .Net Windows App]

• Repair ext4 filesystem on USB drive

  - by phineas

  Yet another filesystem question. I wanted to use a USB drive that I hadn't mounted for a month or so and was surprised by the fact Ubuntu was unable to mount it. I looked it up in the disk utility and it said it discovered a device with 17 MB instead of 2 GB. The hardware looks intact, I hope for the best for repairing the ext4 filesystem. I followed the instructions from HOWTO: Repair a broken Ext4 Superblock in Ubuntu, but I wasn't successful. # fsck.ext4 -v /dev/sdb e2fsck 1.42.5 (29-Jul-2012) ext2fs_open2: Bad magic number in super-block fsck.ext4: Superblock invalid, trying backup blocks... fsck.ext4: Bad magic number in super-block while trying to open /dev/sdb The superblock could not be read or does not describe a correct ext2 filesystem. If the device is valid and it really contains an ext2 filesystem (and not swap or ufs or something else), then the superblock is corrupt, and you might try running e2fsck with an alternate superblock: e2fsck -b 8193 Filesystem blocks are invalid, however when I run the recommended solution to try the alternate superblock, I get the following output: # e2fsck -b 8193 /dev/sdb e2fsck 1.42.5 (29-Jul-2012) e2fsck: Invalid argument while trying to open /dev/sdb plus the same error message as in the last paragraph above. Any ideas how to recover the drive? Thank you very much! Edit: testdisk won't help. I'm still stunned why the tools only discover 17 MB.

• Switching mdadm to an external bitmap

  - by Oli

  I've just read this in another post about improving RAID5/6 write speeds: After increasing stripe cache & switching to external bitmap, my speeds are 160 Mb/s writes, 260 Mb/s reads. :-D I've already found out how to increase the stripe cache and this worked pretty well but I'd like to know more about an external bitmap. I have an incredibly fast (540MB/s) RAID0 SSD that would do well if a bitmap does what I think it does but I'm still very unsure. I've only known about them as long as I've known this post. A few questions: What is a bitmap (in terms of mdadm)? What are the advantages of an internal bitmap (over external)? What are the advantages of an external bitmap (over internal)? How do I switch between the two? I should add that while this is a I'm-bored-let's-break-something thread, I do value the data stored on the RAID array. If doing this is going to put data at significant risk, please let me know.

• Antenna Aligner Part 6: Little Robots

  - by Chris George

  A week ago I took temporary ownership of a HTC Desire S so that I could start testing my app under Android. Support for Android was not in my original plan, but when Nomad added support for it recently, I starting thinking why not! So with some trepidation, I clicked the Build for Android button on the Nomad toolbar... nothing. Hmm... that's not right, I was expecting something to build. After a bit of faffing around I finally realised that I hadn't read the text on the Android setup page properly (yes that's right, RTFM!), and I needed a two-part application identifier, separated by a dot. I did this (not sure what the two part thing is all about, that one my list to investigate!) After making the change, the Android build worked and created the apk file. I uploaded this to the device and nervously ran it... it worked!!!  Well, more or less! So, there was not splash screen, but this was no surprise because I only have the iOS icons and splash screen in my project at the moment. What was more concerning was the compass update didn't seem to be working. I suspect this is a result of using an iOS specific option in the Phonegap compass watcher. Another thing to investigate. I've also just noticed that the css gradient background hasn't worked either... These issues aside, it was actually more successful than I was expecting, so happy days! Right, lets get Googling...   Next time: Preparing for submission to the App Store! :-)

• Learning Programming during the job?

  - by Hossein

  Introduction: I have read and heard advice, about learning programming by accepting programming projects. I need real assistance to understand this, because: Problem: Although, it would seem to me that one would gain much more technical knowledge by doing, real world projects, if one doesn't know much about a technology, it would add much more risk to the actual delivery of the final product! Even the smallest of real world projects could be too much for a newbie. There is a contradiction here: You need to know the job to do it! and It's recommended to do the job, in order to learn it! Question: Any personal experiences in this case would be very pleasant to know while describing: How new was the subject to you? didn't have a clue at all? Or, did you have experience with similar technologies? Was it a solo project or were you in a team? If team, then did others help you with learning it? Did it work as expected? Did you deliver on time? Do you recommend this approach to others as well?

• JustCode &ndash; Color Identifier Basics

  Color identifiers make it easier for developers to quickly read and understand the code on screen.  One of the many features provided by JustCode is the ability to colorize additional items that Visual Studio does not allow you to colorize by default.  The colorization of items such as methods, properties, events, variables, and method parameters can easily be tweaked to your specific needs. Enable / Disable Color Identifiers In the recent release, we turned this option on by default.  You can enable/disable code colorization by going to the JustCode menu in Visual Studio, selecting options, then selecting the general section in the left window.  When you scroll down on general setting you will see a check box that says Color Identifiers.  Check or uncheck this box to enable/disable code colorization.    Color identifiers option   Adjust Color Identifiers Adjusting the color identifiers in JustCode is done in the same place ...Did you know that DotNetSlackers also publishes .net articles written by top known .net Authors? We already have over 80 articles in several categories including Silverlight. Take a look: here.

• Law of Demeter confusion [duplicate]

  - by user2158382

  This question already has an answer here: Rails: Law of Demeter Confusion 4 answers I am reading a book called Rails AntiPatterns and they talk about using delegation to to avoid breaking the Law of Demeter. Here is their prime example: They believe that calling something like this in the controller is bad (and I agree) @street = @invoice.customer.address.street Their proposed solution is to do the following: class Customer has_one :address belongs_to :invoice def street address.street end end class Invoice has_one :customer def customer_street customer.street end end @street = @invoice.customer_street They are stating that since you only use one dot, you are not breaking the Law of Demeter here. I think this is incorrect, because you are still going through customer to go through address to get the invoice's street. I primarily got this idea from a blog post I read: http://www.dan-manges.com/blog/37 In the blog post the prime example is class Wallet attr_accessor :cash end class Customer has_one :wallet # attribute delegation def cash @wallet.cash end end class Paperboy def collect_money(customer, due_amount) if customer.cash < due_ammount raise InsufficientFundsError else customer.cash -= due_amount @collected_amount += due_amount end end end The blog post states that although there is only one dot customer.cash instead of customer.wallet.cash, this code still violates the Law of Demeter. Now in the Paperboy collect_money method, we don't have two dots, we just have one in "customer.cash". Has this delegation solved our problem? Not at all. If we look at the behavior, a paperboy is still reaching directly into a customer's wallet to get cash out. Can somebody help me clear the confusion. I have been searching for the past 2 days trying to let this topic sink in, but it is still confusing.

• Electricsheep Not Working in Raring 13.04

  - by Nhoeh37

  I just downloaded Electricsheep four days before I updated my Ubuntu software and I fell in love with it. After I upgraded to 13.04, I'm kind of upset in saying that Electricsheep no longer works. I have no idea how to fix it and I feel helpless with Linux. As I said, it was working completely fine in 12.10, but now with the Raring Ringtail update: I use Xscreensaver to launch Electricsheep. When I open Xscreensaver, "Electricsheep" is one of the options to choose. When I "preview" ES or even launch the "xscreensaver-demo" in the terminal, it doesn't work anymore; I get an error message. The error message says: "detected another electric sheep process. rendering of sheep is disabled using read only access." Damnit, can someone please help me? I want my trippy screensaver back, it shouldn't be this hard! EDIT: I contacted the creator of Electricsheep (Scott Draves) via the link to his email address on his personal website and asked for his assistance. Hopefully the Askubuntu community will be able to fix this problem, I'm sure I am not the only one who is having this problem as I have searched and searched.

• Is encoding needed in this decryption?

  - by Lijo

  I have a Encryption – Decryption scenario as shown below. //[Clear text ID string as input] -- [(ASCII GetByte) + Encoding] -- [Encrption as byte array] -- [Database column is in VarBinary] -- [Pass byte[] as VarBinary parameter to SP for comparison] //[ID stored as VarBinary in Database] -- [Read as byte array] -- [(Decrypt as byte array) + Encoding + (ASCII Get String)] -- Show as string in the UI My question is in the decryption scenario. After decryption I get a byte array. I am doing an encoding (IBM037) after that. Is it correct? Is there something wrong in the flow shown above? private static byte[] GetEncryptedID(string id) { Interface_Request input = new Interface_Request(); input.RequestText = Encodeto64(id); input.RequestType = Encryption; ProgramInterface inputRequest = new ProgramInterface(); inputRequest.Test_Trial_Request = input; using (KTestService operation = new KTestService()) { return ((operation.KTrialOperation(inputRequest)).Test_Trial_Response.ResponseText); } } private static string GetDecryptedID(byte[] id) { Interface_Request input = new Interface_Request(); input.RequestText = id; input.RequestType = Decryption; ProgramInterface request = new ProgramInterface(); request.Test_Trial_Request = input; using (KTestService operationD = new KTestService()) { ProgramInterface1 response = operationD.KI014Operation(request); byte[] decryptedValue = response.ICSF_AES_Response.ResponseText; Encoding sourceByteFormat = Encoding.GetEncoding("IBM037"); Encoding destinationByteFormat = Encoding.ASCII; //Convert from one byte format to other (IBM to ASCII) byte[] ibmEncodedBytes = Encoding.Convert(sourceByteFormat, destinationByteFormat,decryptedValue); return System.Text.ASCIIEncoding.ASCII.GetString(ibmEncodedBytes); } } private static byte[] EncodeTo64(string toEncode) { byte[] dataInBytes = System.Text.ASCIIEncoding.ASCII.GetBytes(toEncode); Encoding destinationByteFormat = Encoding.GetEncoding("IBM037"); Encoding sourceByteFormat = Encoding.ASCII; //Convert from one byte format to other (ASCII to IBM) byte[] asciiBytes = Encoding.Convert(sourceByteFormat, destinationByteFormat, dataInBytes); return asciiBytes; }

• Help parsing long (3.5mil lines) text file, line by line and storing data, need a strategy

  - by Jarrod

  This is a question about solving a particular problem I am struggling with, I am parsing a long list of text data, line by line for a business app in PHP (cron script on the CLI). The file follows the format: HD: Some text here {text here too} DC: A description here DC: the description continues here DC: and it ends here. DT: 2012-08-01 HD: Next header here {supplemental text} ... this repeats over and over for a few hundred megs I have to read each line, parse out the HD: line and grab the text on this line. I then compare this text against data stored in a database. When a match is found, I want to then record the following DC: lines that succeed the matched HD:. Pseudo code: while ( the_file_pointer_isnt_end_of_file) { line = getCurrentLineFromFile title = parseTitleFrom(line) matched = searchForMatchInDB(line) if ( matched ) { recordTheDCLines // <- Best way to do this? } } My problem is that because I am reading line by line, what is the best way to trigger the script to start saving DC lines, and then when they are finished save them to the database? I have a vague idea, but have yet to properly implement it. I would love to hear the communities ideas\suggestions! Thank you.

• How long does it take to delete a Google Apps for Domain account and allow recreation?

  - by Wil

  Basically, I set up a Google Apps for domain account for one of my clients but upon trying to upload a CSV of users, only half were created and then I kept getting time outs, 404's and other errors which I never saw when setting up another client. I was not sure how, but thought I may have caused an error or there was an error Google Side when the account was created so I thought it may be best to delete the domain and start from scratch. Little did I know, you had to wait to recreate the domain! As far as I can tell from what I have read, there is five days to delete and allow recreation of similar user names, however, I can't see anything that shows how long you have to wait for the domain account. It has now been 5/6 days and I can't recreate it. The cancellation email I got shows "...If at any time you would like to sign-up for Google Apps for this or another domain, you can do so by visiting..." But it does not mention how long!!! I tried emailing Google directly but got no response. Does anyone know?

• Booting Ubuntu 13.10 form USB on server with no OS (Dell PowerEdge T110)

  - by user35581

  I have a Dell PowerEdge T110 (Xeon 1220v2) server with no OS. From my mac, I was able to save the Ubuntu 13.10 for server iso (x86) and used UNetbootin to save the iso to a USB stick (2GB). I was hoping to boot the server from USB, and all seemed to be going well, BIOS even detected my USB drive when I plugged it in, but for some reason I'm getting a "Missing operating system" error. I checked the USB drive and it appears that UNetbootin put the correct files on it form a cursory glance (although I'm not entirely sure what I should be looking for). Should I be able to boot a server with no OS from a UNetbootin created Ubuntu 13.10 USB? And if so, why might BIOS not find the right files? I had read that there is a USB Emulation setting in BIOS, but I haven't been able to find this in the menus. My understanding is that by default, this is set to on. I might try wiping the USB stick and running UNetbootin again. The USB is formatted to MS-DOS FAT16 (should it be formatted some other way?).

What was more concerning was the compass update didn't seem to be working. I suspect this is a result of using an iOS specific option in the Phonegap compass watcher. Another thing to investigate. I've also just noticed that the css gradient background hasn't worked either... These issues aside, it was actually more successful than I was expecting, so happy days! Right, lets get Googling...   Next time: Preparing for submission to the App Store! :-)

• Is this a ridiculous way to structure a DB schema, or am I completely missing something?

  - by Jim

  I have done a fair bit of work with relational databases, and think I understand the basic concepts of good schema design pretty well. I recently was tasked with taking over a project where the DB was designed by a highly-paid consultant. Please let me know if my gut intinct - "WTF??!?" - is warranted, or is this guy such a genius that he's operating out of my realm? DB in question is an in-house app used to enter requests from employees. Just looking at a small section of it, you have information on the users, and information on the request being made. I would design this like so: User table: UserID (primary Key, indexed, no dupes) FirstName LastName Department Request table RequestID (primary Key, indexed, no dupes) <...> various data fields containing request details UserID -- foreign key associated with User table Simple, right? Consultant designed it like this (with sample data): UsersTable UserID FirstName LastName 234 John Doe 516 Jane Doe 123 Foo Bar DepartmentsTable DepartmentID Name 1 Sales 2 HR 3 IT UserDepartmentTable UserDepartmentID UserID Department 1 234 2 2 516 2 3 123 1 RequestTable RequestID UserID <...> 1 516 blah 2 516 blah 3 234 blah The entire database is constructed like this, with every piece of data encapsulated in its own table, with numeric IDs linking everything together. Apparently the consultant had read about OLAP and wanted the 'speed of integer lookups' He also has a large number of stored procedures to cross reference all of these tables. Is this valid design for a small to mid-sized SQL DB? Thanks for comments/answers...

• Office arangement - comfort vs. teamwork?

  - by finrod

  Our team works in an open-space office. Luckily the cubicles are quite big (L shaped tables for everyone!), there is quite a lot of space so we are not sandwiched. Without going into further detail, there are comfortable spots (window), normal spots and stupid spots (near the corridor). Until recently, the development team of twelve engineers was seated so that all types of spots were occupied and we were all close together. In the old arrangement, verbal communication was very easy - half of the team was withing talking distance. The other half was like ten steps away. Often times I could ask, discuss, solve problems without leaving the cube. Most of the communication is work related, no bullshit or mental masturbation that would unnecessarily distract others. Now we have moved to another part of the building and have larger space to occupy. At this point, everyone could pick their spot. Naturally all stupid spots are left empty (for the poor newcomers to occupy bwehaha). In the new arrangement, the development team is stretched across the floor and some of the key engineers are seated 'far' from each other - definitely not within talking distance. I have yet to experience how this works out but am getting concerned that team work and communication may have been traded for personal comfort. Finally the questions... What do you think is better office arrangement? Such that allows for free verbal communication but trading for some developer's comfort, or such that potentially hinders verbal communication but makes developer's more comfortable in their spot? Or maybe it does not matter at all and we will evolve to be efficient in any arrangement? What is your personal experience? Note - yes I read books and posts how workplace is important in our job. However in this case - we are all still in open space and the difference between the different spots are not really groundbreaking. So I'm thinking the little comfort that few developers gain is not worth the loss of easy communication.
