  • How to add my program to the OS X system menu bar?

    - by Joe
    I have created a volume controller for iTunes but I would like this app to place an icon on the OS X system menu bar and have my slider controller drop down. I created this because I have to switch to iTunes to change the volume of the music because I am using the digital-out audio and the keyboard keys do not work in digital-out mode. Any guidance would be greatly appreciated.

  • AOL Contact API and AIM Buddy API

    - by Joe Davis
    I've searched the AOL Developer network and found a Contacts API page that says "coming soon" and is dated last year. I've checked the SDK and APIs and found some AIM Buddy references... I'm looking for documentation on retrieving contact email addresses on behalf of users based on their AOL email login. Am I missing something or is the documentation really difficult to find? Does someone have a useful link?

  • Is NSPasteboard thread-safe?

    - by Joe
    Is it safe to write data to an NSPasteboard object from a background thread? I can't seem to find a definitive answer anywhere. I think the assumption is that the data will be written to the pasteboard before the drag begins. Background: I have an application that is fetching data from Evernote. When the application first loads, it gets the meta data for each note, but not the note content. The note stubs are then listed in an outline view. When the user starts to drag a note, the notes are passed to the background thread that handles getting the note content from Evernote. Having the main thread block until the data is gotten results in a significant delay and a poor user experience, so I have the [outlineView:writeItems:toPasteboard:] function return YES while the background thread processes the data and invokes the main thread to write the data to the pasteboard object. If the note content gets transferred before the user drops the note somewhere, everything works perfectly. If the user drops the note somewhere before the data has been processed... well, everything blocks forever. Is it safe to just have the background thread write the data to the pasteboard?

  • Need explanation of hexagonal architecture

    - by Victor Grazi
    I am reading about Alistair Cockburn's Hexagonal Architecture http://alistair.cockburn.us/Hexagonal+architecture with interest. One claim he makes is: "Finally, the automated function regression tests detect any violation of the promise to keep business logic out of the presentation layer. The organization can detect, and then correct, the logic leak." I do not understand this point. Is he saying that because the test is headless, then calls to a ui layer will throw exceptions? That doesn't seem to be a very sound test!

  • Webdav -- GET on a directory

    - by Joe Cannatti
    I am beginning to build a tool that uses WebDAV. I am having trouble wrapping my head around something here. I think I am missing something conceptual. I can use PUT's to add files to the server. I can use GET's to read files from the server, but when I try to use GET on a directory I get a 403:Forbidden. I am using basic authentication. My code in MacRuby is as follows Net::HTTP.start('localhost') do |http| res = Net::HTTP::Get.new('http://localhost/webdav/') res.basic_auth 'jcannatti', 'webdav' http.request res end this returns <Net::HTTPForbidden 403 Forbidden readbody=true> however this Net::HTTP.start('localhost') do |http| res = Net::HTTP::Put.new('http://localhost/webdav/gorilla.txt') res.body = "testetsetest" res.basic_auth 'jcannatti', 'webdav' http.request res end returns <Net::HTTPCreated 201 Created readbody=true> What should happen when calling a GET on a WebDAV directory when everything is working correctly? thanks

  • Managing string resources in a Java application - singleton?

    - by Joe Attardi
    I seek a solution to the age-old problem of managing string resources. My current implementation seems to work well, but it depends on using singletons, and I know how often singletons can be maligned. The resource manager class has a singleton instance that handles lookups in the ResourceBundle, and you use it like so: MessageResources mr = MessageResources.getMessageResources(); // returns singleton instance ... JLabel helloLabel = new JLabel(mr.getString("label.hello")); Is this an appropriate use of a singleton? Is there some better, more universally used approach that I'm not aware of? I understand that this is probably a bit subjective, but any feedback I can get would be appreciated. I'd rather find out early on that I'm doing it wrong than later on in the process. Thanks!

  • Modify EXE to stop launching firefox

    - by Random Joe
    I'm using a wireless modem program from my ISP. This program automatically disconnect when it detects the line is idle. It does so in 2-5 minutes of idle time. Whenever I reconnect, It will automatically fire up my default browser to the ISP portal. I DID NOT pay them to shove their web portal in my face 50 times a day. The ISP provides no options for disabling this behavior. Can someone please show me how to hex edit the EXE program to stop it from annoying the hell out of me?

  • Web API Getting Http 500 error : Issue Solved See Below

    - by Joe Grasso
    Here is my MVC Controller and everything is fine: private UnitOfWork UOW; public InventoryController() { UOW = new UnitOfWork(); } // GET: /Inventory/ public ActionResult Index() { var products = UOW.ProductRepository.GetAll().ToList(); return View(products); } Same method call in API Controller gives me an Http 500 Error: private UnitOfWork _unitOfWork; public TestController() { _unitOfWork = new UnitOfWork(); } public IEnumerable<Product> Get() { var products = _unitOfWork.ProductRepository.GetAll().ToList(); return products; } Debugging shows that indeed there is data being returned in both controllers' UOW calls. I then added a customer configuration in Global: public static void CustomizeConfig(HttpConfiguration config) { config.Formatters.Remove(config.Formatters.XmlFormatter); var json = config.Formatters.JsonFormatter; json.SerializerSettings.ContractResolver = new CamelCasePropertyNamesContractResolver(); } I am still receiving an Http 500 in API Controller ONLY and at a loss as to why. Any ideas? UPDATE: It appears using lazy loading caused the problem. When I set the associated properties to NON-VIRTUAL the Test API provided the necessary JSON string. However, whereas before I had the Vendor class included, I only have VendorId. I really wanted to included the associated classes. Any ideas? I know there are alot of smart people out there. Anyone?

  • How to extract valid email from larger string in Scala

    - by luigi-prog
    My scala version 2.7.7 Im trying to extract an email adress from a larger string. the string itself follows no format. the code i've got: import scala.util.matching.Regex import scala.util.matching._ val Reg = """\b[A-Z0-9._%+-]+@[A-Z0-9.-]+\.[A-Z]{2,4}\b""".r "yo my name is joe : [email protected]" match { case Reg(e) => println("match: " + e) case _ => println("fail") } the Regex passes in RegExBuilder but does not pass for scala. Also if there is another way to do this without regex that would be fine also. Thanks!

  • Static variables in Java for a test oObject creator

    - by stevebot
    Hey, I have something like the following TestObjectCreator{ private static Person person; private static Company company; static { person = new Person() person.setName("Joe"); company = new Company(); company.setName("Apple"); } public Person createTestPerson(){ return person; } public Person createTestCompany(){ return company; } } By applying static{} what am I gaining? I assume the objects are singletons as a result. However, if I did the following: Person person = TestObjectCreator.createTestPerson(); person.setName("Jill"); Person person2 = TestObjectCreator.createTestPerson(); would person2 be named Jill or Joe?

  • How will Qt 5.0 be packaged for Raring?

    - by George Edison
    Note: as per the FAQ, "Issues with the next version of Ubuntu" may not be asked as questions here but in my opinion, this is not an issue but merely a question asking about policy. If you feel this question is off-topic, please leave a comment explaining why or open a question on Meta.AU. How will Qt 5.0 be packaged for Ubuntu when it is released? Currently, the name of the package for installing the Qt 4.8 core libraries is: libqt4-core Will the equivalent package for the next version of Qt (5.0) be named libqt5-core? If not, what will the package be named? Will the existing Qt 4.8 libraries coexist with the Qt 5.0 equivalents for the foreseeable future or will they be removed? The Qt 5.0 beta 2 PPA contains a lot of packages - few of which seem to correspond with existing package names. If someone can provide me with a link to a policy outlining the Qt 5.0 migration plan, that would be awesome.

  • Aggregate Functions on subsets of data based on current row values with SQL

    - by aasukisuki
    Hopefully that title makes sense... Let's say I have an employee table: ID | Name | Title | Salary ---------------------------- 1 | Bob | Manager | 15285 2 | Joe | Worker | 10250 3 | Al | Worker | 11050 4 | Paul | Manager | 16025 5 | John | Worker | 10450 What I'd like to do is write a query that will give me the above table, along with an averaged salary column, based on the employee title: ID | Name | Title | Salary | Pos Avg -------------------------------------- 1 | Bob | Manager | 15285 | 15655 2 | Joe | Worker | 10250 | 10583 3 | Al | Worker | 11050 | 10583 4 | Paul | Manager | 16025 | 15655 5 | John | Worker | 10450 | 10583 I've tried doing this with a sub-query along the lines of: Select *, (select Avg(e2.salary) from employee e2 where e2.title = e.title) from employee e But I've come to realize that the sub-query is executed first, and has no knowledge of the table alias'd e I'm sure I'm missing something REALLY obvious here, can anyone point me in the right diretion?

  • [PHP] access array element by value

    - by Brandon
    array( [0] name => 'joe' size => 'large' [1] name => 'bill' size => 'small' ) I think i'm being thick, but to get the attributes of an array element if I know the value of one of the keys, I'm first looping through the elements to find the right one. foreach($array as $item){ if ($item['name'] == 'joe'){ #operations on $item } } I'm aware that this is probably very poor, but I am fairly new and am looking for a way to access this element directly by value. Or do I need the key? Thanks, Brandon

  • How to control CSS class applied to ASP.NET 4 Menu with RenderingMode=List

    - by Joe
    I am using an ASP.NET 4.0 Menu control with RenderingMode=List and am struggling with creating the appropriate CSS. Each menu item is represented by an <li tag that contains a nested <a tag with what appear to be fixed class names: <a class="level1" for unselected level 1 menu items <a class="level2" for unselected level 2 menu items <a class="level1 selected" for the selected level 1 menu item ... etc... What I want to do is to is to prevent the currently selected menu item from being "clickable". To do so I tried using: if (menuItem.Selected) menuItem.Selectable = false; This has the desired effect of removing the href attribute from the <a tag but also removes the class attribute - and as a result my CSS can not identify what level the menu item belongs to! Looks to me like a possible bug, but in any case I can't find any documentation describing what CSS class names are used, nor whether there is any way to control this (the old Style properties don't appear to have any effect). Ideally I would like to have "level" class attributes on the <li tags, not just the nested <a tags.

  • Help Reading Binary Image Data from SQL Server into PHP

    - by Joe Majewski
    I cannot seem to figure out a way to read binary data from SQL server into PHP. I am working on a project where I need to be able to store the image directly in the SQL table, not on the file system. Currently, I have been using a query like this one: INSERT INTO myTable(Document) SELECT * FROM OPENROWSET(BULK N'C:\image.jpg', SINGLE_BLOB) as BLAH This works fine to actually insert the image into the table, but I haven't yet figured a way to retrieve it and get my image back. I am doing this with PHP, and ultimately will have to make a stored procedure out of it, but can anyone enlighten me on a way to get that binary data (varbinary(MAX)) and generate an image on the fly. I expected it to be simple to use a SELECT statement and add a content-type to the headers that indicated it was an image, but it's simply not working. Instead, the page will just display the name of the file, which I have encountered in the past and understand it to be an error with the image data.

  • Segmenting a double array of labels

    - by Ami
    The Problem: I have a large double array populated with various labels. Each element (cell) in the double array contains a set of labels and some elements in the double array may be empty. I need an algorithm to cluster elements in the double array into discrete segments. A segment is defined as a set of pixels that are adjacent within the double array and one label that all those pixels in the segment have in common. (Diagonal adjacency doesn't count and I'm not clustering empty cells). |-------|-------|------| | Jane | Joe | | | Jack | Jane | | |-------|-------|------| | Jane | Jane | | | | Joe | | |-------|-------|------| | | Jack | Jane | | | Joe | | |-------|-------|------| In the above arrangement of labels distributed over nine elements, the largest cluster is the “Jane” cluster occupying the four upper left cells. What I've Considered: I've considered iterating through every label of every cell in the double array and testing to see if the cell-label combination under inspection can be associated with a preexisting segment. If the element under inspection cannot be associated with a preexisting segment it becomes the first member of a new segment. If the label/cell combination can be associated with a preexisting segment it associates. Of course, to make this method reasonable I'd have to implement an elaborate hashing system. I'd have to keep track of all the cell-label combinations that stand adjacent to preexisting segments and are in the path of the incrementing indices that are iterating through the double array. This hash method would avoid having to iterate through every pixel in every preexisting segment to find an adjacency. Why I Don't Like it: As is, the above algorithm doesn't take into consideration the case where an element in the double array can be associated with two unique segments, one in the horizontal direction and one in the vertical direction. To handle these cases properly, I would need to implement a test for this specific case and then implement a method that will both associate the element under inspection with a segment and then concatenate the two adjacent identical segments. On the whole, this method and the intricate hashing system that it would require feels very inelegant. Additionally, I really only care about finding the large segments in the double array and I'm much more concerned with the speed of this algorithm than with the accuracy of the segmentation, so I'm looking for a better way. I assume there is some stochastic method for doing this that I haven't thought of. Any suggestions?

  • Why is it necessary to install EFI/rEFInd/UEFI/... on a SD Card since the Macbook Pro seems to already have it?

    - by user170794
    Dear askubuntu members, I own a Macbook Pro (late 2009) and when I boot the laptop and hold the alt key meanwhile, there is a EFI screen, so EFI is installed on... the firmware? I had a few troubles with my hard disk, so I had to change it, but I haven't installed OS X, I have only installed Ubuntu and still the EFI screen is there which is surely a good thing. As the new hard disk is making troubles again, I am using Puppy Linux, booting from a CD each time, which is unconfortable. So I am trying to have Ubuntu installed on a SD Card. After having spent many months on the internet grabing informations anywhere I can and trying several things, I applied this method: http://www.weihermueller.de/mac/ I succeeded in making one SD Card recognizable by the EFI of my laptop (holding alt key @ boot), but nothing installed on it yet as I fear to lose the recognizable-by-EFI part. I haven't succeded in producing the same result on another SD Card. I have a bootable USB key of Ubuntu (yipee) which works like a live CD, made with the help of Universal Linux UDF Creator, found there: http://www.pendrivelinux.com/universal-usb-installer-easy-as-1-2-3/ on which I have put Ubuntu 13.04 64bit, retrieved from the official deposits. Eventhough I have to add the "nouveau.noaccel=1" option to the grub command line launching Linux, it works (yipee again) properly as a live cd. When installing Ubuntu I come across the "where do I wanna put Ubuntu" window, I partition another SD Card in: the EFI part (40MB) the Linux part (15GB< <16GB) The installation works fine and finishes with no problem. But at the reboot, the SD Card where Linux is installed is not recognized by the EFI, the icons are : the CD (Puppy Linux), the USB stick (from Linux UDF Creator), the hard drive (the formerly-working Ubuntu 12) but no fourth icon of the SD Card whatsoever. As the title of this thread suggests, I am wondering: why there is a need for EFI to be installed on the SD Card since EFI seems to be on my laptop anyway? why EFI has to be on a different partition than the Linux's one? How do both parts communicate? why the EFI part on the SD Card made with the help of the live-USB key isn't recognized? on the EFI partition, there is a folder named "EFI" which contains another folder named "ubuntu" which contains a file named "grubx64.efi", why is there a thing called grub? Is it the Linux's grub where one can chose either to boot, to boot in safe mode, etc.? Thank you for your patience, looking forward for any kind of answer, Julien

  • Convert Form to UserControl

    - by Joe
    I have a 3rd party code library that I'm using; part of this library is a winforms application for editing the configuration files used by this library. I would like to embed their configuration editor app into my application. I have the source code to their library and the configuration editor is (as far as I can tell) a straight forward Winforms app using standard controls. I'm trying to convert the app's main form into a UserControl so that I can host it inside my application which is WPF (WPF's WindowsFormsHost won't host a Form object, I get an exception). I changed the form object to inherit from UserControl instead of Form and fixed all the compiler errors (there weren't many, just property initializations that don't exist on UserControls) but what's happening is my newly converted control is just blank. When I run my test app I don't see any of the controls that make up the original form, just a blank page. Any ideas? I really don't want to have to re-implement their app from scratch, that would suck. Edit: I forgot to mention I'm testing this in a WinForms application, not WPF, to just get the control working before trying to use it from WPF.

  • Query Concatenated Field (using SubSonic)

    - by jwynveen
    Is there a way to query against a concatenated field using MS SQL? For instance, what I want to do is something like: Select FirstName+' '+LastName as FullName from Attendees where FullName like '%Joe Schmoe%' The above doesn't work. What I have found works is: Select * from Attendee where FirstName+' '+LastName like '%Joe Schmoe%' but I can't figure out how to do that using a SubSonic SqlQuery. I have a number of joins and OR statements added dynamically that I don't want to have to write out the sql manually. Any help/ideas?

  • Is it too early to start designing for Task Parallel Library?

    - by Joe Erickson
    I have been following the development of the .NET Task Parallel Library (TPL) with great interest since Microsoft first announced it. There is no doubt in my mind that we will eventually take advantage of TPL. What I am questioning is whether it makes sense to start taking advantage of TPL when Visual Studio 2010 and .NET 4.0 are released, or whether it makes sense to wait a while longer. Why Start Now? The .NET 4.0 Task Parallel Library appears to be well designed and some relatively simple tests demonstrate that it works well on today's multi-core CPUs. I have been very interested in the potential advantages of using multiple lightweight threads to speed up our software since buying my first quad processor Dell Poweredge 6400 about seven years ago. Experiments at that time indicated that it was not worth the effort, which I attributed largely to the overhead of moving data between each CPU's cache (there was no shared cache back then) and RAM. Competitive advantage - some of our customers can never get enough performance and there is no doubt that we can build a faster product using TPL today. It sounds fun. Yes, I realize that some developers would rather poke themselves in the eye with a sharp stick, but we really enjoy maximizing performance. Why Wait? Are today's Intel Nehalem CPUs representative of where we are going as multi-core support matures? You can purchase a Nehalem CPU with 4 cores which share a single level 3 cache today, and most likely a 6 core CPU sharing a single level 3 cache by the time Visual Studio 2010 / .NET 4.0 are released. Obviously, the number of cores will go up over time, but what about the architecture? As the number of cores goes up, will they still share a cache? One issue with Nehalem is the fact that, even though there is a very fast interconnect between the cores, they have non-uniform memory access (NUMA) which can lead to lower performance and less predictable results. Will future multi-core architectures be able to do away with NUMA? Similarly, will the .NET Task Parallel Library change as it matures, requiring modifications to code to fully take advantage of it? Limitations Our core engine is 100% C# and has to run without full trust, so we are limited to using .NET APIs.

  • Suggestions needed on an architecture for a multiple clients and customisable web application

    - by ValidfroM
    Our product is a web based course managemant system. We have 10+ clients and in future we may get more clients. (Asp.net,SQL Server) Currently if one of our customers need extra functionality or customised business logic, we will change the db schema and code to meet the needs. (we only have one branch code base and one database schema) To make the change wont affect each others route, we use a client flag, which defined in a web config file, thus those extra fields and biz logic only applied to a particular customer's system. if(ClientId = 'ABC') { //DO ABC Stuff } else { //Normal Route } One of our senior colleagues said, in this way, small company like us can save resources on supporting multiple resources. But what I feel is, this strategy makes our code and database even harder to maintain. Anyone there crossed similar situation? How do you handle that?

  • Default values - are they good or evil?

    - by Andrew
    The question about default values in general - default return function values, default parameter values, default logic for when something is missing, default logic for handling exceptions, default logic for handling the edge conditions etc. For a long time I considered default values to be a "pure evil" thing, something that "cloaks the catastrophe" and results in a very hard do find bugs. But recently I started to think about default values as some sort of a technical debt ... which is not a straight bad thing but something that could provide some "short term financing" get us to survive the project (how many of us could afford to buy a house without taking out the mortgage?). When I say a "short term" - I don't mean - "do something quickly first and do refactor it out later before it hits the production". No - I am talking about relying on a hardcoded default values in a production software. Granted - it could cause some issues, but what if it only going to cause a single trouble in a whole year. Again - I am talking about the "average" mainstream software here (not a software for a nuclear power station) - the average web site or a UI application for the accounting software, meaning that people lives are not at stake, nor millions of dollars. Again, from my experience, business users would rather live with the software which "works somehow", rather then wait for a perfect one. And the use of default values helps a lot if you develop a software in a RAD style. But again - the longest debug sessions I have spent were because of the bugs introduced by a default value which either stopped being "a default" along the way or because a small subsystem has recently been upgraded and as a result of this upgrade it does not handle the default correctly (e.g. empty list vs null, or null string vs empty string). So my question is - are the default values good or evil. And if they are a technical debt - how do measure up how much you can borrow so you can afford the repayments? Would really appreciate any input. Cheers. EDIT: If I am using the default values as a way to cut the corners during the development - and if the corners cutting results in a bugs and issues - what is the methodology to recover from these issues?
