  • Testcase runner for parametrized testcases

    - by Razer
    Let me explain my situation. I'm planning a kind of test case runner for doing testcases on external devices, which are microcontroller based. Lets consider the devices: Device 1 Device 2 There exist a lot of test cases which can be run with one of the devices above. For example: Testcase 1 Testcase 2 The main reason that all the testcases can be run with any device is, that the testcases validates some standard and this software should be extensible for future devices. The testcases itself must be runnable with changing parameters. For example Testcase 1 does some Timing Verification the testcase needs as input parameter the datarate: 4800, 9600, 19200. Now hoping you understand the situation, let me explain my design questions. For implementing the test cases I thought about an Attribute based approach, like nunit does it. The more complicated problem is, how to define the parametrized testcases? Like this: Device 1: Testcase 1: datarate: 4800, 9600, 19200 Testcase 2: supply: 1, 2, 3 Device 2: Testcase 1: datarate: 9600, 19200, 38400 Testcase 2: supply: 3, 4, 5 How would you design such a framework? I've done a similar desin in python where I had for every device a XML containing the testcase definitions like: <Testcase="Testcase 1" datarate=4800/> <Testcase="Testcase 1" datarate=9600/> <Testcase="Testcase 1" datarate=19200/>

  • configuring USB modem( Huawei EC156) in ubuntu 13.10

    - by user205427
    I am facing difficulty in installing my USB modem in Ubuntu 13.10. Contrary to what many have suggested,it does not get detected automatically, nor does setting a new connection help. USB Device is listed in lsusb, but not under network manager or Devices, it is detected as a CD-ROM, what I understood from the web was that usb-modeswitch can be used to switch it to a USB device. Even 'Enable Mobile Broadband' option is not shown in network manager. What was interesting is when I start laptop with windows 7 and use the USB modem and after that restart with Ubuntu, both Enable Broadband and the mobile broadband connection can be seen. Sadly, internet connection could not be installed. I tried using USB-modeswitch command as suggested somewhere, but it does not seem to work. Following is the message. Take all parameters from the command line * usb_modeswitch: handle USB devices with multiple modes * Version 2.0.1 (C) Josua Dietze 2013 * Based on libusb1/libusbx !

  • Ubuntu 12.04 installation on GPT + RAID going into grub rescue

    - by Proy
    I have two 2TB disks. I am installing Ubuntu 12.04 using the alternate version of the server cd. On the partitioning page I have done my partitioning as follows /dev/sda1 - 32 MB - bios_grub /dev/sda2 - 50 GB -raid device /dev/sda3 - 8 GB -raid device /dev/sda4 - Balance full GB - raid device /dev/sdb1 - 32 MB - bios_grub /dev/sdb2 - 50 GB -raid device /dev/sdb3 - 8 GB -raid device /dev/sdb4 - Balance full GB - raid device After this I have setup raid devices /dev/md0 for /(/dev/sda2 + /dev/sdb2) for / ext4 /dev/md1 for swap( /dev/sda3 + /dev/sdb3)for swap /dev/md2 for /home(/dev/sda4 + /dev/sdb4)for /home ext4 The installation finishes it shows that it is installing grub to /dev/sda and /dev/sdb. But once the system reboots it falls into grub rescue mode. on doing ls I can not see the md devices only hd once. I also tried booting into rescue mode with the install cd and doing grub-install /dev/sda and /dev/sdb. What am I doing wrong ? Why is grub2 not detecting the raid revices ? UPDATE: I just did the same steps with Ubuntu 10.04 and it worked perfectly fine. I wiped out the RAID and partitions and everything and did it from scratch. I think the issue is with Ubuntu 12.04 and the way it partitions 2 TB disks

  • Copying photos from camera stalls - how to track down issue?

    - by Hamish Downer
    When I copy files from my camera (connected via USB) to the SSD in my laptop a few files get copied and then the copy stalls. I'm not sure why, any ideas or things to investigate appreciated, or bug reports to go and look at. I have read this answer - the camera (Canon 40D in case that matters) mounts fine using gvfs. I can see the photos in Nautilus, or in the terminal (in /run/user/username/gvfs/... ) and I can copy a few photos, but not many. Using the terminal or Nautilus the process hangs until the camera goes to sleep. Digikam fails to copy any at all, as does Rapid Photo Downloader. Shotwell did manage it in the end, but that is very much a work around for me. I have disabled thumbnail generation by nautilus. Load average stays about 1 while this is happening, while CPU usage is half idle, half wait (and a little user/sys for other programs). None of the programs at the top of the cpu list in top are related to copying photos. There is not much in the logs - from /var/log/syslog Dec 2 16:20:52 mishtop dbus[945]: [system] Activating service name='org.freedesktop.UDisks' (using servicehelper) Dec 2 16:20:52 mishtop dbus[945]: [system] Successfully activated service 'org.freedesktop.UDisks' Dec 2 16:21:24 mishtop kernel: [ 2297.180130] usb 2-2: new high-speed USB device number 4 using ehci_hcd Dec 2 16:21:24 mishtop kernel: [ 2297.314272] usb 2-2: New USB device found, idVendor=04a9, idProduct=3146 Dec 2 16:21:24 mishtop kernel: [ 2297.314278] usb 2-2: New USB device strings: Mfr=1, Product=2, SerialNumber=0 Dec 2 16:21:24 mishtop kernel: [ 2297.314283] usb 2-2: Product: Canon Digital Camera Dec 2 16:21:24 mishtop kernel: [ 2297.314287] usb 2-2: Manufacturer: Canon Inc.

  • USB Ports In Wrong Mode, How To Use usbmodeswitch?

    - by user86872
    I haven't had access to my USB ports as media devices for a couple days now. I've been reading and researching everything I can find but I can't find a good guide for usbmodeswtich or usbms that I can decipher. The USB's are fine for power, but won't support my android phone as a media device, which is killing me because I use adb everyday, and won't support my plug and play mouse any longer. Not sure what caused the switch, though I think it may be related to the suspend issue I've read about, but the solutions in those threads I read also didn't work. Below is my system information and details.

  • How to determine if a 3D voxel-based room is sealed, efficiently

    - by NigelMan1010
    I've been having some issues with efficiently determining if large rooms are sealed in a voxel-based 3D rooms. I'm at a point where I have tried my hardest to solve the problem without asking for help, but not tried enough to give up, so I'm asking for help. To clarify, sealed being that there are no holes in the room. There are oxygen sealers, which check if the room is sealed, and seal depending on the oxygen input level. Right now, this is how I'm doing it: Starting at the block above the sealer tile (the vent is on the sealer's top face), recursively loop through in all 6 adjacent directions If the adjacent tile is a full, non-vacuum tile, continue through the loop If the adjacent tile is not full, or is a vacuum tile, check if it's adjacent blocks are, recursively. Each time a tile is checked, decrement a counter If the count hits zero, if the last block is adjacent to a vacuum tile, return that the area is unsealed If the count hits zero and the last block is not a vacuum tile, or the recursive loop ends (no vacuum tiles left) before the counter is zero, the area is sealed If the area is not sealed, run the loop again with some changes: Checking adjacent blocks for "breathable air" tile instead of a vacuum tile Instead of using a decrementing counter, continue until no adjacent "breathable air" tiles are found. Once loop is finished, set each checked block to a vacuum tile. Here's the code I'm using: http://pastebin.com/NimyKncC The problem: I'm running this check every 3 seconds, sometimes a sealer will have to loop through hundreds of blocks, and a large world with many oxygen sealers, these multiple recursive loops every few seconds can be very hard on the CPU. I was wondering if anyone with more experience with optimization can give me a hand, or at least point me in the right direction. Thanks a bunch.

  • Ethernet Connection Unavailable

    - by fabikw
    I'm running Ubuntu Server 12.04 on a laptop with an Intel NIC (driver e1000e). When I connect the ethernet port to the internet (college network, DHCP) it works out of the box. Now I'm trying to connect it to a networked USRP (if you want to know what it is). A friend of mine managed to do this in his laptop (running regular Ubuntu 12.04) just by setting up a new Wired connection in the Network Manager with appropriate addresses. However, when I do the same, no wired connections are available. The output of nmcli -p dev is =========================================== Status of devices =========================================== DEVICE TYPE STATE ------------------------------------------- wlan0 802-11-wireless connected eth0 802-3-ethernet unavailable but the cable is connected to the device and the device is powered up. Any idea how to solve this? UPDATE: After stopping the network-manager service, setting up the connection manually and starting the service again, it now detects the ethernet connection. However, the device still can't receive data and doesn't answer to pings. UPDATE 2: As suggested I tried using a cross over cable but the result is exactly the same. However, I found out that connecting the device to the dock (as opposed to directly to the laptop) works fine. I know that the ethernet port in the laptop works fine, because connecting to the network through it works. Is it possible that the port in the laptop doesn't support Gb Ethernet (because that's what the device requires) but the one in the dock does?

  • Kindle App for WP7 arrives

    - by dotgeek
    If you had asked me if I was interested in owning a Kindle device, then my response a couple months back would have been a flat out no back then. So what has changed between now on then you might be asking me then? I would have to say watching my wife enjoy the many books in digital form has peeked my interest to start with now. Was that enough for me to buy a Kindle though? Not just yet, but that is where the Windows Phone 7 comes in for me once again. It’s no secret that I’ve wanted this device and yes it does have a number of Apps that I think I’ll really enjoy. The latest must have App for me, will most certainly be the Kindle App for Windows Phone 7, released from Amazon today. I’ve already started playing around with the PC version of Kindle software and I’m looking at purchasing any future books in digital form now. So it’s a given once I have a Windows Phone 7 device, that I’ll be enjoying some of my favorite books, while I’m on the go I think and via this App. Tonight I actually had a chance to check out the WP7 Kindle App on a friends device and I was really pleased with how it looked and performed. Now if the planets could only manage to lineup for me and allow Verizon and Microsoft to come to terms on the releasing of WP7 CDMA devices, I just might be able to really enjoy some of this on my own. Do I rule out ever having an actual Kindle device? Not at all, but I do plan on having the WP7 device well before that day ever comes though.

  • USB flash module giving errors

    - by vshenoy
    Hi, I have a SATA USB flash module which was earlier running a 2.4 linux kernel (2.4.36.6) and on which now I am trying to install ubuntu server 10.04.1 LTS. I have two such USB flash modules and on one of them the installation process itself giving these errors: sd 4:0:0:0 [sda] Device not ready sd 4:0:0:0 [sda] Result: hostbyte=DID_OK driverbyte=DRIVER_SENSE sd 4:0:0:0 [sda] Sense Key : Not Ready [current] sd 4:0:0:0 [sda] Add.

  • Simple C: atof giving wrong value [migrated]

    - by Doc
    I have a program that reads input from a singe line(string obviously) and organizes it into arrays. The problem I have is that at one point the program reads two different values and returns the first one twice. Initially I thought the program was reading the same value twice but when I tested it turned out that it got the correct one but is inputting the wrong one. for example Input: 2 0.90 0.75 0.7 0.65 sorry to snip it (while(fgets (string[test], sizeof(string[test]),ifp)) pch = strtok_r(NULL, " ", &prog); tem3 = atoi(pch); while (loop<tem3) { pch=strtok_r(NULL," ",&prog); venseatfloat[test][loop][DISCOUNT][OCCUPIED]=(float)atof(pch); printf("%f is discount\t",venseatfloat[test][loop][DISCOUNT][OCCUPIED]); pch=strtok_r(NULL, " ", &prog); strcpy(temp, pch); venseatfloat[test][loop][REGULAR][OCCUPIED]=(float)atof(pch); printf("%s is the string but %.3f is regular\n", temp ,venseatfloat[test][loop][DISCOUNT][OCCUPIED]); loop++; } output: >0.900000 is discount 0.75 is the string but 0.900 is regular >0.700000 is discount 0.65 is the string but 0.700 is regular What is going on?

  • USB ports not working on Xubuntu 12.04 LTS

    - by Zchpyvr
    Basically, my USB ports on my IBM Thinkpad T43 have stopped working most of the time. Sometimes, they mount and appear in Nautilus, but other times, they aren't recognized. The timeline of events on this laptop for the past few months: Started having problems after using a USB port hub. The port would sometimes work but would be fixed with the occasional reboot. Re-partitioned/Expanded my Xubuntu partition (I have a Windows XP/Xubuntu dual boot). Now the majority of the time, the USB fails to recognize devices. In addition, the few times they are recognized, the device may suddenly disconnect. Things I've noticed: The devices still receive power from my computer (I can charge my ipod..etc..) I can't understand dmesg outputs. I don't know if lsusb is telling me anything useful. My dmesg output is here: http://pastebin.com/KdNxHcFC Things start to get weird at the bottom of the file. And my lsusb is: $ lsusb Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub Bus 002 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub Bus 003 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub Bus 004 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub Bus 005 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub

  • DirectX: Render to a screen buffer without using a render target

    - by knight666
    Hello, I'm writing an open source 2D game engine, and I want to support as many devices and platforms as possible. I currently only have Windows Mobile though. I'm rendering using DirectX Mobile, with DirectDraw as a fallback path. However, I've run into a bit of trouble. It seems that while the reference driver supports createRenderTarget, many many many physical devices do not. I need some way to render to the screen without using a render target, because I render sprites using textured quads, but I also need to be able to draw individual pixels. This is how I do it right now: // save old values if (Error::Failed(m_D3DDevice->GetRenderTarget(&m_D3DOldTarget))) { ERROR_EXPLAIN("Could not retrieve backbuffer."); return false; } // clear render surface if (Error::Failed(m_D3DDevice->SetRenderTarget(m_D3DRenderSurface, NULL))) { ERROR_EXPLAIN("Could not set render target to render texture."); return false; } if (Error::Failed (m_D3DDevice->Clear( 0, NULL, // target rectangle D3DMCLEAR_TARGET, D3DMCOLOR_XRGB(0, 0, 0), // clear color 1.0f, 0 ) ) ) { ERROR_EXPLAIN("Failed to clear render texture."); return false; } D3DMLOCKED_RECT render_rect; if (Error::Failed(m_D3DRenderSurface->LockRect(&render_rect, NULL, NULL))) { ERROR_EXPLAIN("Failed to lock render surface pixels."); } else { m_D3DBackSurf->SetBuffer((Pixel*)render_rect.pBits); m_D3DRenderSurface->UnlockRect(); } // begin scene if (Error::Failed(m_D3DDevice->BeginScene())) { ERROR_EXPLAIN("Failed to start rendering."); return false; } // ===================== // example rendering // ===================== // some other stuff, but the most important part of rendering a sprite: device->SetTexture(0, m_Texture)); device->SetStreamSource(0, m_VertexBuffer, sizeof(Vertex)); device->DrawPrimitive(D3DMPT_TRIANGLELIST, 0, 2); // plotting a pixel Surface* target = (Surface*)Device::GetRenderMethod()->GetRenderTarget(); buffer = target->GetBuffer(); buffer[somepixel] = MAKECOLOR(255, 0, 0); // end scene if (Error::Failed(device->EndScene())) { ERROR_EXPLAIN("Failed to end scene."); return false; } // clear screen if (Error::Failed(device->SetRenderTarget(m_D3DOldTarget, NULL))) { ERROR_EXPLAIN("Couldn't set render target to backbuffer."); return false; } if (Error::Failed(device->GetBackBuffer ( 0, D3DMBACKBUFFER_TYPE_MONO, &m_D3DBack ) ) ) { ERROR_EXPLAIN("Couldn't retrieve backbuffer."); return false; } RECT dest = { 0, 0, Device::GetWidth(), Device::GetHeight() }; if (Error::Failed( device->StretchRect ( m_D3DRenderSurface, NULL, m_D3DBack, &dest, D3DMTEXF_NONE ) ) ) { ERROR_EXPLAIN("Failed to stretch render texture to backbuffer."); return false; } if (Error::Failed(device->Present(NULL, NULL, NULL, NULL))) { ERROR_EXPLAIN("Failed to present device."); return false; } I'm looking for a way to do the same thing (render sprites using hardware acceleration and plot pixels on a buffer) without using a render target. Thanks in advance.

  • iPhone app memory leak with UIImage animation? Problem testing on device

    - by user157733
    I have an animation which works fine in the simulator but crashes on the device. I am getting the following error... Program received signal: “0”. The Debugger has exited due to signal 10 (SIGBUS) A bit of investigating suggests that the UIImages are not getting released and I have a memory leak. I am new to this so can someone tell me if this is the likely cause? If you could also tell me how to solve it then that would be amazing. The images are 480px x 480px and about 25kb each. My code is below... NSArray *rainImages = [NSArray arrayWithObjects: [UIImage imageNamed:@"rain-loop0001.png"], [UIImage imageNamed:@"rain-loop0002.png"], [UIImage imageNamed:@"rain-loop0003.png"], [UIImage imageNamed:@"rain-loop0004.png"], [UIImage imageNamed:@"rain-loop0005.png"], [UIImage imageNamed:@"rain-loop0006.png"], //more looping images [UIImage imageNamed:@"rain-loop0045.png"], [UIImage imageNamed:@"rain-loop0046.png"], [UIImage imageNamed:@"rain-loop0047.png"], [UIImage imageNamed:@"rain-loop0048.png"], [UIImage imageNamed:@"rain-loop0049.png"], [UIImage imageNamed:@"rain-loop0050.png"], nil]; rainImage.animationImages = rainImages; rainImage.animationDuration = 4.15/2; rainImage.animationRepeatCount = 0; [rainImage startAnimating]; [rainImage release]; Thanks

  • How do you save images to a Blackberry device via HttpConnection?

    - by Kai
    My script fetches xml via httpConnection and saves to persistent store. No problems there. Then I loop through the saved data to compose a list of image url's to fetch via queue. Each of these requests calls the httpConnection thread as so ... public synchronized void run() { HttpConnection connection = (HttpConnection)Connector.open("http://www.somedomain.com/image1.jpg"); connection.setRequestMethod("GET"); String contentType = connection.getHeaderField("Content-type"); InputStream responseData = connection.openInputStream(); connection.close(); outputFinal(responseData, contentType); } public synchronized void outputFinal(InputStream result, String contentType) throws SAXException, ParserConfigurationException, IOException { if(contentType.startsWith("text/")) { // bunch of xml save code that works fine } else if(contentType.equals("image/png") || contentType.equals("image/jpeg") || contentType.equals("image/gif")) { // how to save images here? } else { //default } } What I can't find any good documentation on is how one would take the response data and save it to an image stored on the device. Maybe I just overlooked something very obvious. Any help is very appreciated. Thanks

  • How to do logout functionality in C# smart device application?

    - by Shailesh Jaiswal
    I am developng Smart device application in C#. It is a window application. In this application I am using Login form to authenticate the users. Only authenticated users can login into the system. In this application I am calling java web services which resides on another machine. I am passing mobile number & password from mu application's login form to the java web services. The java web services returns the userid after successful authentication. I made this userid static so that it can be used frequently with other web services. I using statc variables in this application so that they can be used at application level. After deploying the application I can see that emulator provides the close button with multiplicaton symbol. In this way I can close my form as well as application. But I want to provde one logout link in my application. Can I provide logout functionality in C# window application ? If yes, how to do that ? Please make sure that all the functions of .net framework does not work with .net compact framwork? Can you provide me the code or link through which can resolve the above issue ?

  • How to get a handle to all JCheckBox objects in order to loop?

    - by EmmyS
    I'm very new to Java and am having some issues looping through JCheckBoxes on a UI. The idea is that I have a bunch of checkboxes (not in a group because more than one can be selected.) When I click a JButton, I want to build a string containing the text from each selected checkbox. The issue I'm having is that our instructor told us that the checkboxes need to be created via a method, which means (see code below) that there isn't a discrete instance name for each checkbox. If there were, I could say something like if(checkBox1.isSelected()) { myString.append(checkBox.getText()); } That would repeat for checkBox2, checkBox3, and so on. But the method provided to us for adding checkboxes to a panel looks like this: public class CheckBoxPanel extends JPanel { private static final long serialVersionUID = 1L; public CheckBoxPanel(String title, String... options) { setBorder(BorderFactory.createTitledBorder(BorderFactory .createEtchedBorder(), title)); setLayout(new BoxLayout(this, BoxLayout.Y_AXIS)); // make one checkbox for each option for (String option : options) { JCheckBox b = new JCheckBox(option); b.setActionCommand(option); add(b); } } } This is called like this: toppingPanel = new CheckBoxPanel("Each Topping $1.50", "Tomato", "Green Pepper", "Black Olives", "Mushrooms", "Extra Cheese", "Pepperoni", "Sausage"); So I now have a panel that contains a border with the title "Each Topping $1.50", and 7 visible checkboxes. What I need to do is get a list of all the selected toppings. We are not supposed to use an ActionListener for each checkbox, but rather get the list when a button is clicked. I'm feeling really clueless here, but I just can't figure out how to get the isSelected property of the checkboxes when the individual checkboxes don't have instance names. Ideally I'd like to somehow add all the checkboxes to an array and loop through the array in the button's action listener to determine which ones are checked, but if I have to check each one individually I will. I just can't figure out how to refer to an individual checkbox when they've been created dynamically.

  • How can I create a horizontal table in a single foreach loop in MVC?

    - by GenericTypeTea
    Is there any way, in ASP.Net MVC, to condense the following code to a single foreach loop? <table class="table"> <tr> <td> Name </td> <% foreach (var item in Model) { %> <td> <%= item.Name %> </td> <% } %> </tr> <tr> <td> Item </td> <% foreach (var item in Model) { %> <td> <%= item.Company %> </td> <% } %> </tr> </table> Where model is a simple object: public class SomeObject { public virtual Name {get;set;} public virtual Company {get;set;} } This would output a table as follows: Name | Bob | Sam | Bill | Steve | Company | Builder | Fireman | MS | Apple | I know I could probably use an extension method to write out each row, but is it possible to build all rows using a single iteration over the model? This is a follow on from this question as I'm unhappy with my accepted answer and cannot believe I've provided the best solution.

  • PHP Arrays: Loop trough array with a lot of conditional statements. Help / Best practices

    - by Jonathan
    Hi, I have a problem I don't know how to get it to work the best way. I need to loop trough an array like the one below. I need to check if the [country] index is equal to a Spanish speaking country (lot of countries) and then get those [title] indexes of the correspondent country and check for duplicates. The original array: Array ( [0] => Array ( [title] => Jeux de pouvoir [country] => France ) [1] => Array ( [title] => Los secretos del poder [country] => Argentina ) [2] => Array ( [title] => Los secretos del poder [country] => Mexico ) [3] => Array ( [title] => El poder secreto [country] => Uruguay ) ) To help you understand, the final result I need to get looks something like this: Array ( [0] => Array ( [title] => Los secretos del poder [country] => Argetnina, Mexico ) [1] => Array ( [title] => El poder secreto [country] => Uruguay ) )

  • Using AND vs && in a for loop (Not related to precedence?)

    - by Peter
    Why is it that this code prints "Hello!" four times and then prints "1": <?php for ($i=1 AND $blah=1; $i<5; $i++) echo("Hello!"); echo($blah); ?> While this doesn't print out "Hello!" at all and then prints "1": <?php for ($i=1 && $blah=1; $i<5; $i++) echo("Hello!"); echo($blah); ?> I know AND and && have different precedences, but that doesn't seem to apply here. What am I missing? (I'm using a variant of the code above, since I will use $blah within the for loop, and I want to set the value for it). Thanks for any help!

  • What is the proper way to code a read-while loop in Scala?

    - by ARKBAN
    What is the "proper" of writing the standard read-while loop in Scala? By proper I mean written in a Scala-like way as opposed to a Java-like way. Here is the code I have in Java: MessageDigest md = MessageDigest.getInstance( "MD5" ); InputStream input = new FileInputStream( "file" ); byte[] buffer = new byte[1024]; int readLen; while( ( readLen = input.read( buffer ) ) != -1 ) md.update( buffer, 0, readLen ); return md.digest(); Here is the code I have in Scala: val md = MessageDigest.getInstance( hashInfo.algorithm ) val input = new FileInputStream( "file" ) val buffer = new Array[ Byte ]( 1024 ) var readLen = 0 while( readLen != -1 ) { readLen = input.read( buffer ) if( readLen != -1 ) md.update( buffer, 0, readLen ) } md.digest The Scala code is correct and works, but feels very un-Scala-ish. For one it is a literal translation of the Java code, taking advantage of none of the advantages of Scala. Further it is actually longer than the Java code! I really feel like I'm missing something, but I can't figure out what. I'm fairly new to Scala, and so I'm asking the question to avoid falling into the pitfall of writing Java-style code in Scala. I'm more interested in the Scala way to solve this kind of problem than in any specific helper method that might be provided by the Scala API to hash a file. (I apologize in advance for my ad hoc Scala adjectives throughout this question.)
