  • Help with Hashmaps in Java

    - by Crystal
    I'm not sure how I use get() to get my information. Looking at my book, they pass the key to get(). I thought that get() returns the object associated with that key looking at the documentation. But I must be doing something wrong here.... Any thoughts? import java.util.*; public class OrganizeThis { /** Add a person to the organizer @param p A person object */ public void add(Person p) { staff.put(p, p.getEmail()); System.out.println("Person " + p + "added"); } /** * Find the person stored in the organizer with the email address. * Note, each person will have a unique email address. * * @param email The person email address you are looking for. * */ public Person findByEmail(String email) { Person aPerson = staff.get(email); return aPerson; } private Map<Person, String> staff = new HashMap<Person, String>(); public static void main(String[] args) { OrganizeThis testObj = new OrganizeThis(); Person person1 = new Person("J", "W", "111-222-3333", "[email protected]"); testObj.add(person1); System.out.println(testObj.findByEmail("[email protected]")); } }

  • Finding optimal ddrescue command line options where Accuracy > Speed

    - by gav
    I'm read up a bit about this tool and obviously looked at the man pages. The trouble is that ddrescue takes so long I need to get the command right first time. I wasn't sure how to improve on the vanilla; $ sudo ./ddrescue -v /dev/disk0s5 MyVolImage.dmg MyVolRescue.log $ sudo ./ddrescue -v MyVolImage.dmg /dev/disk1s3 MyVolRestore.log From HSF+ to HSF+ drives Source (Broken) HDD is connected via USB 2.0 Dest HDD is inside MacBook I would choose accuracy over speed There seem to be a lot of options but I'm not sure how they impact quality and speed of recovery. Thanks, Gav

  • Write Null/Nothing value with Databinding

    - by clawson
    I have extended a MaskedTextBox component to add some functionality. The text property of the extended MaskedTextBox is bound to a DateTime? property and the format of binding is set to a time format of "HH:mm:ss" (i.e. 24hr time). So that this masked text box will capture the display a time. The extra functionality I have added is to make the component readonly unless the component is double clicked or the enter button is pressed (the back color of the control helps to inform the users if the component is locked/readonly or not). When the enter button is pressed I also suspend the bindings so that bound data is updated the users input won't be lost. The information is then written back to the value and databindings resumed when the user presses the enter key again. This all works fine up to here, with values written and displayed as would be expected. However, I also want to write the null or nothing value to the DateTime? property if the user hasn't entered any text (or invalid text but let's just stick with no text) when enter key is pressed to submit the new value. Unlike with other valid entries in the MaskedTextBox, with no text entered when i execute: Me.DataBindings("Text").WriteValue() (when 'locking' the MaskedTextBox) it then branches to the bound properties Get method as I step into each line of code in the debugger (as opposed to the Set method with other valid entries) How can I write this null/nothing/"" value to the DateTime? property when no text "" is entered into the MaskedTextBox? Thanks for the help!

  • mac osx script - find mounted disc with name, copy file from desktop to it, when copy complete, unmount disc

    - by Joshc
    Is there some kind of mac script which finds a newly mounted disc drive that has the name 'EXAMPLE', then copies a file/folder to it and safely ejects the disc when copy has finished? I don't mind if the script needs to be executed by a short cut. And will it work if there are multiple drives plugged in? The reason I am asking is becuase i have 5000 usb memory sticks that I need to copy about 20mb worth of data to it. Thanks in advance for any ideas.

  • What is the simplest and fastest way to transfer large file through a Windows network?

    - by Sake
    I have a Window Server 2000 machine running MS SQL Server that stores over 20GB of data. The database is backed-up every day to the second harddrive. I want to transfer those backup files to another computer to build another test server and for recovery practicing. (the backup never actually got restored for almost 5 years. Don't tell my boss about that!) I have trouble transfering that huge file through the network. I've tried plain network copy, apache download, and ftp. Any method I tried end up failing when the amount of data transfered reach 2GB. The last time that I successfully transfered the file, it was through a usb attached external harddrive. But I want to perform this task routinely and preferably automatically. Wonder what is the most pragmatic approach for this situation ?

  • Installing linux on a crippled machine via network boot?

    - by networkbooter
    I have a somewhat ancient Toshiba laptop (which can't boot from USB) that I want to install linux on (probably Ubuntu). I'm currently running Windows XP and Ubuntu via Wubi. I want to delete these OSs and replace with Ubuntu only. The laptop does have a network boot option. I'm wondering if the easiest way might be to setup a network boot server on my other computer (which runs Ubunutu) and boot the laptop from it. Could this allow me to install Linux on the laptop? I can't seem to find instructions on the 'net as to how to go about doing this.

  • Problems with blocking reads using libudev on Linux

    - by Steve Hawkins
    We are using the following routine (on Linux, with libudev) to read data from a PIC microcontroller configured as a USB HID device. The data is sent only when a button connected to the PIC microcontroller is pressed or released. The routine is missing messages from the PIC controller, and I suspect that this is because the call to poll below is not behaving as it should. The call to poll will reliably block for 1 second util the first message is read. As soon as the first message is read, the call to poll returns immediately instead of blocking for 1 second (1000 milliseconds) like it should. I have worked around this problem by closing and re-opening the device after each read. This makes poll behave correctly, but I think that closing and re-opening the device may be the reason for the lost messages. bool PicIo::Receive (unsigned char* picData, const size_t picDataSize) { static hiddev_report_info hidReportInfo; static hiddev_usage_ref_multi hidUsageRef; if (-1 == PicDeviceDescriptor()) { return false; } // Determine whether or not there is data available to be read pollfd pollFd; pollFd.fd = PicDeviceDescriptor(); pollFd.events = POLLIN; int dataPending = poll (&pollFd, 1, 1000); if (dataPending <= 0) { return false; } // Initialize the HID Report structure for an input report hidReportInfo.report_type = HID_REPORT_TYPE_INPUT; hidReportInfo.report_id = 0; hidReportInfo.num_fields = 64; if (-1 == ioctl(PicDeviceDescriptor(), HIDIOCGREPORT, &hidReportInfo)) { return false; } // Initizlize the HID Usage Reference for an Input report hidUsageRef.uref.report_type = HID_REPORT_TYPE_INPUT; hidUsageRef.uref.report_id = 0; hidUsageRef.uref.field_index = 0; hidUsageRef.uref.usage_index = 0; hidUsageRef.num_values = 64; if (-1 == ioctl(PicDeviceDescriptor(), HIDIOCGUSAGES, &hidUsageRef)) { return false; } // Transfer bytes from the usage report into the return value. for (size_t idx=0; (idx < 64) && (idx < picDataSize); ++idx) { picData[idx] = hidUsageRef.values[idx]; } return true; } The function PicDeviceDescriptor() does checking on the device to make sure that it is present. Here are the pertinent details of the PicDeviceDescriptor function, showing how the device is begin opened. int PicIo::PicDeviceDescriptor(int command) { struct stat statInfo; static int picDeviceDescriptor = -1; string picDevicePath = "/dev/usb/hiddev0"; if ((-1 != picDeviceDescriptor) && (CLOSE == command)) { close (picDeviceDescriptor); picDeviceDescriptor = -1; } else if ((-1 != picDeviceDescriptor) && (-1 == fstat(picDeviceDescriptor, &statInfo))) { // Handle the case where the PIC device had previously been detected, and // is now disconnected. close (picDeviceDescriptor); picDeviceDescriptor = -1; } else if ((-1 == picDeviceDescriptor) && (m_picDevice.IsConnected())) { // Create the PIC device descriptor if the PIC device is present (i.e. its // device node is present) and if the descriptor does not already exist picDeviceDescriptor = open (picDevicePath.c_str(), O_RDONLY); } return picDeviceDescriptor; } I'm sure that I'm doing something wrong, but I've Googled the issue and cannot seem to find any relevant answers. Any help would be very much appreciated -- Thx.

  • silverlight treeview not loading subitems

    I'm interested in finding out why this isn't working: I have a treeview with some hierarchicaldatatemplates looking like this: <UserControl.Resources> <sdk:HierarchicalDataTemplate x:Key="nodeEntry"> <StackPanel Orientation="Horizontal"> <TextBlock Text="{Binding Path=Title}" /> </StackPanel> </sdk:HierarchicalDataTemplate> <sdk:HierarchicalDataTemplate x:Key="rootEntry" ItemsSource="{Binding Path=Nodes}" ItemTemplate="{StaticResource nodeEntry}"> <StackPanel Orientation="Horizontal"> <TextBlock Text="{Binding Path=Name}" /> </StackPanel> </sdk:HierarchicalDataTemplate> </UserControl.Resources> <sdk:TreeView Height="250" HorizontalAlignment="Left" ItemTemplate="{StaticResource rootEntry}" ItemsSource="{Binding ElementName=subjectDomainDataSource, Path=Data}" Name="rootTreeView" VerticalAlignment="Top" Width="180"/> The data is passed to the treeview from a domainservice using this method: public IEnumerable<Subject> GetSubjectList(Guid userid) { DataLoadOptions loadopts = new DataLoadOptions(); loadopts.LoadWith<Root>(s => s.Nodes); this.DataContext.LoadOptions = loadopts; return this.DataContext.Roots; } why then are only the root nodes shown in the treeview as if it only loaded a flat list, and not a hierarchy where the root Loads the NodesCollection?

  • SQL query for selecting the firsts in a series by cloumn

    - by SP
    I'm having some trouble coming up with a query for what I am trying to do. I've got a table we'll call 'Movements' with the following columns: RecID(Key), Element(f-key), Time(datetime), Room(int) The table is holding a history of Movements for the Elements. One record contains the element the record is for, the time of the recorded location, and the room it was in at that time. What I would like are all records that indicate that an Element entered a room. That would mean the first (by time) entry for any element in a series of movements for that element in the same room. The input is a room number and a time. IE, I would like all of the records indicating that any Element entered room X after time Y. The closest I came was this Select Element, min(Time) from Movements where Time > Y and Room = x group by Element This will only give me one room entry record per Element though (If the Element has entered the room X twice since time Y I'll only get the first one back) Any ideas? Let me know if I have not explained this clearly. I'm using MS SQLServer 2005.

    Hi guys! I'm stuck in a problem, i cannot workaround! I have a Oracle client 11, with registry key set to AMERICAN_AMERICA.WE8ISO8859P1. I cannot edit this key, but my application must get data from Oracle in Italian culture format. So I want to edit culture info form my application only. I'm trying to using OracleGlobalization class in ODP.NET library before my Application.Run(), to set culture for my thread: OracleGlobalization og = OracleGlobalization.GetThreadInfo(); //OracleGlobalization.SetThreadInfo(OracleGlobalization.GetThreadInfo()); og.Calendar = "GREGORIAN"; og.Comparison = "BINARY"; og.Currency = "€"; og.DateFormat = "DD-MON-RR"; og.DateLanguage = "ITALIAN"; og.DualCurrency = "€"; og.ISOCurrency = "ITALY"; og.Language = "ITALIAN"; og.LengthSemantics = "BYTE"; og.NCharConversionException = false; og.NumericCharacters = ",."; og.Sort = "WEST_EUROPEAN"; og.Territory = "ITALY"; OracleGlobalization.SetThreadInfo(og); I get always the same error: ORA-12705: Cannot access NLS data files or invalid environment specified.

  • Windows server 2008 UPS support

    - by Rory McCune
    I'm looking to set-up a UPS on a Windows Small Business Berver 2k8 and I've noticed that there are some large price differences for similar capacity in-line UPSs. The most important point for me in UPS selection is that the server should have the ability to shut itself down before the UPS power runs out, so that if the server is unattended during the outage, it should minimize the risk of data loss. From some reading it appears that Windows Server 2008 should has the ability to natively recognise a UPS, which can then be managed through the battery settings on the server or via WMI. What I'm wondering if anyone know is, Is Windows 2008 servers UPS support specific to certain brands of UPS (eg, APC) or is it likely to work with any UPS which has a USB port, which I can connect to the server?

  • How to make the value of one select box drive the options of a second select box

    - by Ben McCormack
    I want to make an HTML form with 2 select boxes. The selected option in the first select box should drive the options in the second select box. I would like to solve this dynamically on the client (using javascript or jQuery) rather than having to submit data to the server. For example, let's say I have the following Menu Categories and Menu Items: Sandwiches Turkey Ham Bacon Sides Mac 'n Cheese Mashed Potatoes Drinks Coca Cola Sprite Sweetwater 420 I would have two select boxes, named Menu Category and Items, respectively. When the user selects Sandwiches in the Menu Category box, the options in the Items box will only show Sandwich options. I'm stuck as how I might approach this. Once I filter out the 2nd list one time, how do I "find" the list options once I change my menu category in the 1st list? Also, if I'm thinking in SQL, I would have a key in the 1st box that would be used to link to the data in the 2nd box. However, I can't see where I have room for a "key" element in the 2nd box. How could this problem be solved with a combination of jQuery or plain javascript?

  • How can I figure out exactly which process is keeping my Mac from going to sleep and waking it up?

    - by pattern86
    I have read this knowledgebase article, but would like to know if there's a way to tell exactly which process is causing my Mac not to follow the sleep schedule I have set in System Preferences Energy Saver. I have narrowed it down to a being a process and will explain why I think so (see below). I am running OS X (10.6.5) on the new iMac 27" and I am certain it's not the following: The "Wake for Network Access" checkbox in Energy Saver settings (has never been a previous issue) Peripherals (has never been a previous issue) Any active GUI application (all are closed) Additional USB/FireWire drives (none are connected) Bluetooth (it's off) Sharing services (has never been a previous issue) The symptoms are as follows: The computer doesn't go to sleep at the predetermined time. It will wake up some number of hours after being put manually to sleep (but not within the first few seconds/minutes.) Is there a specific string I should be looking for in Console? I have tried searching for "wake" and "sleep" but can't make total sense of the results.

  • script Disk Management configuration

    - by Joseph
    I have 10 workstations with large monitors that have USB slots and several card readers built in. The card readers cannot be disabled and will map to drive letters when I image the computers. I go into Disk Management and delete the drive mappings and add mappings to a single folder in C:\ with a folder for each slot. I have to do this because of scripts that run that are expecting specific letter drive mappings to network resources. Is there a way to script the deleting and adding of drive mappings instead of having to use the Disk Management GUI manually on each workstation? The workstations are running XP Professional.

  • Solution to wirelessly project tablet desktop?

    - by Robert
    I’m trying to find a device that would allow a windows 7 client to wirelessly connect and display their screen to a projector while still connected to the wireless network. The idea is to allow a professor to still project and display content while walking around the room with their tablet. To date, haven’t been able to find a solution that meets the requirements, has anyone stumbled across one yet? Requirements Must support Windows 7 Must be able to connect to WPA2 Personal(and hopefully enterprise) Must not use any usb dongles – those get lost/damaged given a chance. Goal Wirelessly display screen to projector without cables from tablet/laptop.

    I recently got a job as a junior network administrator. Last week the senior admins did their yearly reinstall of server 2003, exchange, drivers etc on the main server. I've been asked to back up the disc so that next year they can just copy over the pre-made image. What tools can i use to achieve both the creation of the entire servers HDD image and loading it back on (id like to test it in the sandbox.) To impress them, a program that is free is preferable. And maybe a tool that can do it all from booting the program off of a USB drive.

  • Location of Embedly (JQuery-Preview) Results

    - by user749798
    Embedly/Jquery-Preview has been fantastic. However, I'm trying to change the location of the preview result, and having trouble. Right now, the result appears right below the input field...but I'd rather have it in a separate part of the page. Is there a way to do this? I've tried changing the location of the selector and loading divs, but that hasn't helped. It seems to ignore those divs and put it right below the submit button. Below is my code: <form accept-charset="UTF-8" action="private" class="new_comment" data-remote="true" id="new_comment" method="post"> <input class="photo_comm" id="comment_comment" name="comment[comment]" placeholder="add a comment or link..." size="30" type="text" /><span type="text" id="counter">1000</span> <input class="btn btn-primary btn-mini" data-disable-with="Submitting..." name="commit" type="submit" value="Post" /> </form> <!-- Placeholder that tells Preview where to put the loading icon--> <div class="loading"> <img src='http://embedly.github.com/jquery-preview/images/loading-rectangle.gif'> </div> <!-- Placeholder that tells Preview where to put the selector--> <div class="selector"></div> $('#comment_comment').preview({ key:'60f1dcdf3258476794784148a6eb65e7', // Sign up for a key: http://embed.ly/pricing selector : {type:'rich'}, preview : { submit : function(e, data){ e.preventDefault(); $.ajax({ dataType: 'script', url: this.form.attr('action'), type: 'POST', data: data }); }, }, autoplay : 0, maxwidth : 400, display : {display : 'rich'} });

  • Is this a safe/valid hash method implementation?

    - by Sean
    I have a set of classes to represent some objects loaded from a database. There are a couple variations of these objects, so I have a common base class and two subclasses to represent the differences. One of the key fields they have in common is an id field. Unfortunately, the id of an object is not unique across all variations, but within a single variation. What I mean is, a single object of type A could have an id between, say, 0 and 1,000,000. An object of type B could have an id between, 25,000 and 1,025,000. This means there's some overlap of id numbers. The objects are just variations of the same kind of thing, though, so I want to think of them as such in my code. (They were assigned ids from different sets for legacy reasons.) So I have classes like this: @class BaseClass @class TypeAClass : BaseClass @class TypeBClass : BaseClass BaseClass has a method (NSNumber *)objectId. However instances of TypeA and TypeB could have overlapping ids as discussed above, so when it comes to equality and putting these into sets, I cannot just use the id alone to check it. The unique key of these instances is, essentially, (class + objectId). So I figured that I could do this by making the following hash function on the BaseClass: -(NSUInteger)hash { return (NSUInteger)[self class] ^ [self.objectId hash]; } I also implemented isEqual like so: - (BOOL)isEqual:(id)object { return (self == object) || ([object class] == [self class] && [self.objectId isEqual:[object objectId]]); } This seems to be working, but I guess I'm just asking here to make sure I'm not overlooking something - especially with the generation of the hash by using the class pointer in that way. Is this safe or is there a better way to do this?

  • Global hotkey capture in VB.net

    - by ggonsalv
    I want to have my app which is minimized to capture data selected in another app's window when the hot key is pressed. My app definitely doesn't have the focus. Additionally when the hot key is pressed I want to present a fading popup (Outlook style) so my app never gets focus. At a minimum I want to capture the Window name, Process ID and the selected data. The app which has focus is not my application? I know one option is to sniff the Clipboard, but are there any other solutions. This is to audit the rate of data-entry in to another system of which I have no control. It is a mainframe emulation client program(attachmate). The plan is complete data entry in Application X. Select a certain section of the screen in App X which is proof of data entry (transaction ID). Press the Magic Hotkey, which then 'sends' the selection to my App. From System.environment or system.Threading I can find the Windows logon. Similiarly I can also capture the time. All the data will be logged to SQL. Once Complete show Outlook style pop up saying the data entry has been logged. Any thoughts.

  • Upgrading Fedora 16 to 17 with crypted LVM

    - by nijansen
    As the title suggests, I want to upgrade Fedora 16 to the Fedora 17 Alpha build, but I am struggling to do so because of my crypted HDD. To avoid the hustle of CD-ROM or USB install, I thought the preupgrade would be a good idea. It downloads the stuff, stores an image somewhere and creates an entry in my boot manager. When I choose to upgrade from the boot manager it crashes halfway through because it can not access any of the prepared files (because it's crypted) and hands me a debug console. Unfortunately, this case apparently is not covered by the Fedora troubleshooting advice, at least I was not able to find anything there. I would guess I have to mount my HDD manually, but 1) how? and 2) how do I resume the upgrade afterwards? I would really appreciate a push in the right direction.

  • What do I need to connect a hard disk to my laptop via non powered eSata?

    - by Ludo
    Hi there. I'm looking at getting a hard disk for my laptop (OCZ Vertex 2 SSD) which I would like to connect via eSata. My laptop has an eSata port, but it's not powered (Thinkpad T410). I presume this means I need more than just an eSata to eSata cable as it needs power, so does this mean I need a caddy for the hard disk as well which will provide power to the drive, or do I need one of them eSata cables that has a USB attachment too? I don't think the drive will come with a power supply. I realise this seems simple but I can't find an obvious answer online. Thanks for any assistance! Ludo.
