• Digital Audio Output light on on MacBook Pro

  - by Emerson Hsieh

  I don't know if this problem happened when I installed Ubuntu before. Recently I noticed that when I boot Ubuntu, the Digital Audio Output light automatically switches on. Digital Audio Output light on means "Something wrong in the headphone port". Although my headphone is working in Ubuntu. I've heard that the headphone contains some magical "switch" that will fix the light problem. So I poked the headphone port with chopsticks, pens, paper clips, even my finger, and the Digital Audio Output light still stays on. I don't have this problem in OSX. How do I switch the light off?

• Virtual Win XP Mode stopped HP LJ Pro M1212nf MFP printing in Win 7 Pro

  - by Dee

  Virtual Win XP Mode stopped HP LJ Pro M1212nf MFP printing in Win 7 Pro: I am running Windows 7 Pro with Virtual Windows XP Mode. My printer is HP LaserJet Pro M1212nf MFP attached directly to a USB port of the computer. This printer was working fine in Windows 7, until I tried to attach the printer to the Virtual Windows XP Mode in order to load the printer driver in the Virtual Windows XP Mode. At that point, the printer disappeared from the list of USB devices on the toolbar at the top of the window of the Virtual Windows XP Mode. After installing the printer driver in the Virtual Windows XP Mode, the printer did not work in that mode and also no longer worked in Windows 7. In Windows 7 and in the Virtual Windows XP Mode, print files are sent to the print queue, but are never printed. In Windows 7, the print queue states that the printer is offline. In the Virtual Windows XP Mode, the printer can be toggled from "Print Offline" to "Print Online", but no print files are ever printed from the print queue. The printer acts as though it is no longer connected to the computer, even though it is still physically connected to the USB port of the computer. How can I get the printer to work again in Windows 7? (At this point, I am no longer interested in using the Virtual Windows XP Mode.) I have tried a large number of things to find and fix the printer problem, but have had no success. Device Manager cannot see the printer even though it is physically connected via USB port (have tried different USB ports) to the computer. Restoring Win 7 and Virtual Win XP Mode to times before the problem does not fix the problem. How can I get the computer to see the printer, so that I can print again in Win 7?

• Calculating WPM given a variable stream of input

  - by Jaxo

  I'm creating an application that sits in the background and records all key presses (currently this is done and working; an event is fired every keydown/keyup). I want to offer a feature for the user that will show them their WPM over the entire session the program has been running for. This would be easy if I added a "Start" and "End" button to activate a timer, but I need to detect only when the user is typing continuously - ignoring all one-time keyboard shortcuts and breaks the user takes from typing. How in the world do I approach this? Is this even realistically & accurately possible?

• Does the retina MacBook Pro Australian charger duckhead have 3 prongs on it or 2?

  - by frenchglen

  I notice that with my Retina MacBook Pro (bought in UK), its charger uses all three prongs to power the laptop (like this, rather than this). Not surprised, it's a powerful machine. I'm going to Australia now and I want to use an aussie duckhead and make use of the innovative design. I have an existing one from an old iPod (and it used to work with fine with my Macbook Air when in australia), but it's only two prongs (like this). Is that enough to power my rMBP? Or will it damage/strain it and I need to find a 3 prong one (if it even exists - I haven't bought my MBP in Australia) like this? Thanks

• exporting clip in Final Cut Pro X or related video editing software on Mac

  - by user46976

  I'm using Final Cut Pro X to edit a 1 hour long video. I made individual clips from it in Final Cut Pro X and I want to save just these clips, some of which are only 5 mins long. How can I do this? I tried using the app ClipExporter, but it won't even read my .fcpxml file, it just says that it's not a valid file and gives no helpful information at all. Another method I tried was to assign roles to each clip. I made one clip, 5 mins long, and then used Share - Export in Final Cut Pro X and chose the option to export roles as separate files. However, the export still estimates that it will take over an hour to export and so it looks like it's trying to export the whole movie, rather than the simple 5 min clip which should be exportable as a .MOV or related formats in a few minutes. How can I do this in final cut pro x? I'm also happy to switch to related video editing software as long as they are not extremely expensive. This seems like a very trivial and obvious feature: take a segment from a long movie and export just the selected region of it... I don't understand why it's so complicated to do in Final Cut Pro X. Thanks.

• External Dell Display doesn't work with MacBook Pro (2011) after Thunderbolt Firmware Update (1.0 and 1.2)

  - by tom

  Today two Thunderbolt Firmware Updates (1.0 and 1.2) became available for my MacBook Pro (Early 2011). After installing both, my external monitor, a Dell U2713HM, does no longer work. The system detects the display, but the display shows only black. An Apple Thunderbolt display works fine and a MacBook Air can use the Dell monitor without problems. My MacBook Pro can use the Dell monitor just fine when I boot from a USB stick. Therefore, clearly the Thunderbolt Firmware Update seems to be the problem. Does anyone have the same problem? Any solutions or workarounds? I guess there is no way to remove a Thunderbolt Firmware Update once it's installed, right? Update 24.10.2013: Is there no one else with this problem? In the meantime I tried three different cables – none worked. My colleague with the same generation MacBook Pro also can't use my display after installing the firmware update. All colleagues with MacBook Airs and newer MacBook Pros (all didn't receive the firmware update) can use the display. Update 29.10.2013: Wow, ok today my new MacBook Pro Retina 13' (Late 2013) arrived. Guess what, I cannot use the display with it. Only HDMI works – not with the full resolution.

• Remote connect into macbook pro at a different resolution

  - by user60277

  Hello, I have a Dell laptop with Windows 7 on it. Its resolution is 1920x1080. I want to connect to a macbook pro at that resolution. The macbook pro has a resolution of 1440x900 so when I VNC into it, I can only see 1440x900 box with black borders on full resolution. The macbook pro can drive resolutions of 2560x1440. What program do I use to connect to the macbook at full (1920x1080) resolution. I can use remote desktop and connect from the dell laptop to another dell laptop that has a 1440x900 max. resolution. However in case of Remote desktop connection I can expand the window to be 1920x1080. I'm using TightVNC viewer on Windows. Thanks

• Trouble cloning a Macbook Pro hard drive

  - by Mirko Froehlich

  I am trying to upgrade the 250GB hard drive in my MacBook Pro (early 2008 model) to a 750GB drive. I have connected the new drive via an external USB enclosure. The drive is recognized fine, I can format it, etc. However, every time I try to clone the drive, I am getting Input/Output errors. Before the clone operation, I have verified both the internal and the external drive using Disk Utility, and they both check out fine. After the clone operation, the external drive shows multiple "Invalid node structure" errors: I have tried two approaches for cloning the drive: Using Disk Utility, by starting from the OSX install DVD Using Carbon Copy Cloner The outcome is the same in both cases. The Carbon Copy Cloner logs show a handful of the following types of errors: rsync: mkstemp "<... an external filename ...>" failed: Input/output error (5) rsync: stat "<... an external filename ...>" failed: Input/output error (5) The actual files affected seem to be different across different runs of the application. Before the last run, I used Disk Utility to (once more) reformat the external drive and explicitly overwrite it with zeros, but this made no difference. I also tried running a surface scan in Tech Tool Pro overnight. It got about 2/3 of the way through before I had to disconnect the drive (had to take my MacBook Pro to work), but so far it didn't report any bad blocks. Assuming it scans the drive in the same order in which blocks would be allocated during actual use, it seems like if bad blocks were to blame for the clone failures, they should have been found already (given that the source drive is only 250GB). As a last attempt, I may try SuperDuper as well, although my understanding is that it uses the same underlying rsync approach as Carbon Copy Cloner, so it's unlikely to perform any better. Are there any other things I should try before I send the drive in for a replacement? Could these problems be caused by my internal drive, even though it works fine and checks out fine in Disk Utility?

• Business Logic Layer Pattern on Rails? MVCL

  - by Fabiano PS

  That is a broad question, and I appreciate no short/dumb asnwers like: "Oh that is the model job, this quest is retarded (period)" PROBLEM Where I work at people created a system over 2 years for managing the manufacture process over demand in the most simplified still broad as possible, involving selling, buying, assemble, The system is coded over Ruby On Rails. The app has been changed lots of times and the result is a mess on callbacks (some are called several times), 200+ models, and fat controllers: Total bad. The QUESTION is, if there is a gem, or pattern designed to handle Rails large app logic? The logic whould be able to fully talk to models (whose only concern would be data format handling and validation) What I EXPECT is to reduce complexity from various controllers, and hard to track callbacks into files with the responsibility to handle a business operation logic. In some cases there is the need to wait for a response, in others, only validation of the input is enough and a bg process would take place. ie: -- Sell some products (need to wait the operation to finish) 1. Set a View able to get the products input 2. Controller gets the product list inputed by employee and call the logic Logic::ExecuteWithResponse('sell', 'products', :prods => @product_list_with_qtt, :when => @date, :employee => current_user() ) This Logic would handle buying order, assemble order, machine schedule, warehouse reservation, and others. Have in mind that a callback on SalesOrder is not enough, since it depends on where it is called (no field for that), depends on the class of the user, among other stuff not visible for the model, or in some cases it would take long for the model to process.

• Thick models Vs. Business Logic, Where do you draw the distinction?

  - by TokenMacGuy

  Today I got into a heated debate with another developer at my organization about where and how to add methods to database mapped classes. We use sqlalchemy, and a major part of the existing code base in our database models is little more than a bag of mapped properties with a class name, a nearly mechanical translation from database tables to python objects. In the argument, my position was that that the primary value of using an ORM was that you can attach low level behaviors and algorithms to the mapped classes. Models are classes first, and secondarily persistent (they could be persistent using xml in a filesystem, you don't need to care). His view was that any behavior at all is "business logic", and necessarily belongs anywhere but in the persistent model, which are to be used for database persistence only. I certainly do think that there is a distinction between what is business logic, and should be separated, since it has some isolation from the lower level of how that gets implemented, and domain logic, which I believe is the abstraction provided by the model classes argued about in the previous paragraph, but I'm having a hard time putting my finger on what that is. I have a better sense of what might be the API (which, in our case, is HTTP "ReSTful"), in that users invoke the API with what they want to do, distinct from what they are allowed to do, and how it gets done. tl;dr: What kinds of things can or should go in a method in a mapped class when using an ORM, and what should be left out, to live in another layer of abstraction?

• MacBook Pro with Time Capsule can not see Samsung CLX 3175FW wireless printer on Bonjour

  - by syncopat

  I have a MacBook Pro running OS X 10.6 and another MacBook Pro running OS X 10.5. Neither see my Samsung printer when I click on Bonjour. Needless to say neither will print. I have a Time Capsule connected wirelessly to my MacBook Pros. I have tried reinstalling drivers for the printer but nothing seems to work. I tried this approach because when Apple replaced my Time Capsule and I went to print the way I had initially been running printing requests would get hung up. Any suggestions would be helpful?

• Mac Book Pro wakes up in my backpack

  - by J. Pablo Fernández

  This has happened to me twice: I press the power button on my Mac Book Pro, choose sleep, close it, unplug everything, confirm that is off (by pressing my ear to it) and put it in my bag. Some minutes later, the laptop wakes up by itself. Both times I caught it in time. The second time it was so hot I couldn't touch some parts -- it refused to actually wake up, and the screen was blank. Restarting it worked though. Any ideas what might be going on and/or how to prevent this? More details: It's a Mac Book Pro unibody 15" from 2009.

• Digital audio does not work on MacBook Pro

  - by mathk

  I have a MacBook Pro (8,2). Using a TOSLINK cable I have no digital output. Oddly enough, sometime I can hear a glitch when I plug in the cable or when I give it a gentle wiggle. My guess is that the output is not correctly detecting that I have a digital link. So is there a way to force digital audio output on a MacBook Pro? Some say that in the Audio MIDI Setup there is an option but I can't find it. I am running OS X 10.7.5.

• MVC: Why put the business logic in the model? What happens when I've multiple types of storage?

  - by Steffen Winkler

  I always thought that the business logic has to be in the controller and that the controller, since it is the 'middle' part, stays static and that the model/view have to be capsuled via interfaces, that way you could change the business logic without affecting anything else, program multiple Models (one for each database/type of storage) and a dozens of views (for different platforms for example). Now I read in this question that you should always put the business logic into the model and that the controller is deeply connected with the view. To me, that doesn't really make sense and implies that each time I want to have the means of supporting another database/type of storage I've to rewrite my whole model including the business logic. And if I want another view, I've to rewrite both the view and the controller. May someone explain why that is or if I went wrong somewhere? Currently, that whole thing doesn't really make sense to me.

• In retrospect, has it been a good idea to use three-valued logic for SQL NULL comparisons?

  - by Heinzi

  In SQL, NULL means "unknown value". Thus, every comparison with NULL yields NULL (unknown) rather than TRUE or FALSE. From a conceptional point of view, this three-valued logic makes sense. From a practical point of view, every learner of SQL has, one time or another, made the classic WHERE myField = NULL mistake or learned the hard way that NOT IN does not do what one would expect when NULL values are present. It is my impression (please correct me if I am wrong) that the cases where this three-valued logic helps (e.g. WHERE myField IS NOT NULL AND myField <> 2 can be shortened to WHERE myField <> 2) are rare and, in those cases, people tend to use the longer version anyway for clarity, just like you would add a comment when using a clever, non-obvious hack. Is there some obvious advantage that I am missing? Or is there a general consensus among the development community that this has been a mistake?

• passive view and display logic

  - by genesys

  Hi! In MVC and MVP and similar patterns there's often the approach of the "passive view" which is as stupid as possible. This should facilitate unit testing and create a clearer separation of view and model. I know that those patterns come in very different flavours and especially the understanding of MVP seems to differ from article to article. Therefore my question is not "how do i implement this pattern correctly". I want to improve view and model separation and go for better testability of the application. Therefore i'd like to go for a passive view. But my question is, where would you put logic that is clearly only view related? like a textviewer should scroll the text when the scrollbar is moved. would you put the logic for this into the Presenter? Let's say the textviewer has some extended functionality. like setting markings on textpassages. The logic for this makes clearly sense to be put into the Presenter. However, if it is mixed with all the 'direct' logic of the view (like scrolling the text) the Presenter could become very big, which is also not really a nice design. So my question is where to put display related logic of a passive view and what functionallity to mix in the Presenter. Thanks!

• How do I improve my logic in general and programming in particular?

  - by Dinesh Venkata

  I'm good with understanding technology and implementing it. At least that is what I feel. But it seems that when I come across experienced programmers they point out that my logic is weak. I feel that I would need some time with real programming to improve it. But nobody is ready to give that time to me. I'm just about starting my carer and it often feels disheartening to hear this. I want know how can I improve my logic and also does this sort of thing happens to others too?
