  • 10 lines of code per day is the global average!? -- true?

    - by Earlz
    Ok so last year I participated in a high school curriculum contest thing at a college(I currently attend this college). I actually got 1st in it but was still a bit angry I didn't get every single one right. The most baffling of questions on there was How many lines of code does the average programmer write per day? A. 5 B. 10 C. 25 D. 30 Aside from being a subjective question which depended on language and everything else I was more baffled at what they had as the correct answer. 10. Even on my bad days at my job I touch more than 10 lines of code(either adding, modifying, or deleting) per day. And when I took this test I had only programmed as a hobby where it was common for me to write a few hundred lines for one of my new projects per day. Where are they getting this random number of ten!? Is this published somewhere? A quick googling found me nothing.

  • Understanding what SPARQL is

    - by user73119
    This is a terribly beginner series of questions, but after reading through a good 30 SPARQL tutorials I can't seem to wrap my head around what SPARQL is or how to begin using it. Is it executed on the client side? Is microsoft somehow going to be able to mess this up? Can you use a common relational database (SQL)? Are there particular resources you recommend over others for learning? Do you feel it is premature to begin investing myself in this? Best way to get set up and running to start tinkering? The RDFA examples I have seen are very inspiring. I am currently a big proponent of using microformats but would really like to take it further. I currently develop in PHP, but have only found a Java library.

  • Grails GORM (Hibernate) query

    - by bsreekanth
    Hello, I'm trying to do the below sql statement in GORM select * from table1 where table1.x not in (select x from table 2 where y='something'); so, I have two tables, and needs to find the entries from table 1 which are not in table 2. In Grails def xx= table2.findByY('something') def c = table1.createCriteria() def result= c.list { not ( in('x', xx) ) } the syntax is wrong, and I'm not sure how to simulate not in sql logic. As a learning point, if someone can also tell me why minus (-) operator in grails/groovy doesn't work with list. I tried getting x and y seperately, and doing x.minus(y), but it doesn't change the list. I saw an explanation at http://stackoverflow.com/questions/1754576/groovy-on-grails-list-not-working , but I would expect the list defined are local. thank you so much.

  • How do you read a segfault kernel log message.

    - by Sullenx
    This can be a very simple question, I'm am attempting to debug an application which generates the following segfault error in the kern.log /var/log/kern.log.0:Jan 8 13:25:56 myhost kernel: myapp[15514]: segfault at 794ef0 ip 080513b sp 794ef0 error 6 in myapp[8048000+24000] Here are my questions: 1) Is there any documentation as to what are the diff error numbers on segfault, in this instance it is error 6, but i've seen error 4, 5 2) What is the meaning of the information at bf794ef0 ip 0805130b sp bf794ef0 and myapp[8048000+24000]? So far i was able to compile with symbols, and when i do a "x 0x8048000+24000" it returns a symbol, is that the correct way of doing it? My assumptions thus far are the following: sp = stack pointer? ip = instruction pointer at = ???? myapp[8048000+24000] = address of symbol?

  • Core Location - fallback, location caching and alternatives...

    - by Moshe
    I have a few questions about Core Location. 1) Should the user refuse permission for my app to use core location, or core location is unavailable for some reason, is there a fallback? (Device Locale, for example?) 2)Can I cache a device's location for next time? Does Core Location do this itself? 3)I really need the sunset time in the user's area during the mid-spring season and I have a function to do that, once I have the Latitude and Longitude of the device. Perhaps I can just make an assumption about the time based on Locale? (Example: In the US, assume approximately 7:00pm.)

  • creating a Grails application in IntelliJ IDEA 9.0.x fails to prompt for "create-app"

    - by dave
    When I create a Grails application in IntelliJ 9 on Snow Leopard I am not prompted to create an application. IntelliJ finished the wizard and creates an empty project that is not a Grails application. I have tried two different Apple computers (MacBook Pro and Mac Pro) it does not work on either. The same steps on a Linux system results in a prompt to "create-app" and a Grails application. I have already tried the steps in http://stackoverflow.com/questions/470882/intellij-idea-setup-on-os-x Is there a specific place that Grails needs to be installed? Has anyone else seen this behavior? Thanks

  • Django: UserProfile with Unique Foreign Key in Django Admin

    - by lazerscience
    Hi, I have extended Django's User Model using a custom user profile called UserExtension. It is related to User through a unique ForeignKey Relationship, which enables me to edit it in the admin in an inline form! I'm using a signal to create a new profile for every new user: def create_user_profile(sender, instance, created, **kwargs): if created: try: profile, created = UserExtension.objects.get_or_create(user=instance) except: pass post_save.connect(create_user_profile, sender=User) (as described here for example: http://stackoverflow.com/questions/44109/extending-the-user-model-with-custom-fields-in-django) The problem is, that, if I create a new user through the admin, I get an IntegritiyError on saving "column user_id is not unique". It doesnt seem that the signal is called twice, but i guess the admin is trying to save the profile AFTERWARDS? But I need the creation through signal if I create a new user in other parts of the system!

  • Converting EBNF to BNF

    - by Vivin Paliath
    It's been a few years since my computer-language class and so I've forgotten the finer points of BNF's and EBNF's and I don't have a textbook next to me. Specifically, I've forgotten how to convert an EBNF into BNF. From what little I remember, I know that one of the main points is to convert { term } into <term> | <many-terms>. But I don't remember the other rules. I've tried to look this up online but I can only find links to either homework questions, or a small comment about converting terms with curly braces. I can't find an exhaustive list of rules that define the translation.

  • ADD COLUMN to sqlite db IF NOT EXISTS - flex/air sqlite?

    - by Adam
    I've got a flex/air app I've been working on, it uses a local sqlite database that is created on the initial application start. I've added some features to the application and in the process I had to add a new field to one of the database tables. My questions is how to I go about getting the application to create one new field that is located in a table that already exists? this is a the line that creates the table stmt.text = "CREATE TABLE IF NOT EXISTS tbl_status ("+"status_id INTEGER PRIMARY KEY AUTOINCREMENT,"+" status_status TEXT)"; And now I'd like to add a status_default field. thanks! Thanks - MPelletier I've add the code you provided and it does add the field, but now the next time I restart my app I get an error - 'status_default' already exists'. So how can I go about adding some sort of a IF NOT EXISTS statement to the line you provided?

  • What are the dark corners of Vim your mom never told you about?

    - by Sasha
    There is a plethora of questions where people talk about common tricks, notably this one. However, I don't refer to commonly used shortcuts that a noob would find cool. I am talking about a seasoned unix user (be she/he a developer, admin, both, etc), who thinks (s)he knows something 99% of us never heard or dreamed about. Something that not only makes his/her work easier, but also is COOL and hackish. After all, vim resides in the most dark-corner-rich OS in the world, thus it should have intricacies that only a few privileged know about and want to share with us.

  • Batch select with SQLAlchemy

    - by muckabout
    I have a large set of values V, some of which are likely to exist in a table T. I would like to insert into the table those which are not yet inserted. So far I have the code: for value in values: s = self.conn.execute(mytable.__table__.select(mytable.value == value)).first() if not s: to_insert.append(value) I feel like this is running slower than it should. I have a few related questions: Is there a way to construct a select statement such that you provide a list (in this case, 'values') to which sqlalchemy responds with records which match that list? Is this code overly expensive in constructing select objects? Is there a way to construct a single select statement, then parameterize at execution time?

  • Why does my .NET Windows service not start automatically sometimes?

    - by Tomek
    Hi all, I have modified a working Windows service that had always been starting beforehand. After adding the System.Management reference it now sometimes will not start automatically. I get the following error: Service cannot be started. System.Runtime.InteropServices.COMException (0x80010002): Call was canceled by the message filter. (Exception from HRESULT: 0x80010002 (RPC_E_CALL_CANCELED)) I found another post here on SO with someone having the same issue. http://stackoverflow.com/questions/998883/why-wont-my-net-windows-service-start-automatically-after-a-reboot However, the proposed solution was to have the service start after the services it depends on have started. However, when I go to the Dependencies tab for my service, I see: Should I just use the workaround method of putting the thread to sleep, or is there a more proper way of getting this service to start correctly? Is this happening because .NET has not started before my service starts? Thanks, Tomek

  • Python Naming Conventions for Dictionaries/Maps/Hashes

    - by pokstad
    While other questions have tackled the broader category of sequences and modules, I ask this very specific question: "What naming convention do you use for dictionaries and why?" Some naming convention samples I have been considering: # 'value' is the data type stored in the map, while 'key' is the type of key value_for_key={key1:value1, key2,value2} value_key={key1:value1, key2,value2} v_value_k_key={key1:value1, key2,value2} Don't bother answering the 'why' with "because my work tells me to", not very helpful. The reason driving the choice is more important. Are there any other good considerations for a dictionary naming convention aside from readability?

  • Is learning the Caché database hard coming from relational databases and object oriented programming

    - by Edelcom
    I am currently running the local version of Caché on my system in order to determine if I can (and will) take on a new possible project. The current project uses Delphi 7 as a front end calling a Caché dll where the business logic is stored in the database. I have a background of Sqlserver and Firebird (and before Access and Paradox) as databases. I use Delphi 7 for 95% of my Windows development, so I know about object programming. I would like to recieve opinions from persons having used Caché and either SqlServer, Firebird or Oracle and having developed in Delphi (or C++ or C# - an object oriented language). I have read the pro's and con's from other questions, but I am not asking for this, I need input from Caché developers. Thanks in advance.

  • What to do with CSV after export on the iPhone?

    - by alku83
    One of the requested features for my apps is to have an export feature. Most of the time the data is table-like in nature. As an example, users might enter every day what types of food they ate that day, and how many portions of each food type. As the data is table-like, I figure the most useful for export would be into CSV format. Then it can be read in spreadsheet software. I'm confident I can get the data into a CSV like format without too much trouble, and found this post would should help me: http://stackoverflow.com/questions/1512883/how-to-convert-data-to-csv-or-html-format What I'm wondering about is what I can do with the file once it has been created? Can I attach it to an email? How else can I make it available to the user so that it has some use? Alternatively, am I going about this the wrong way and would there be a better way to offer an export function?

  • application: didFinishLaunchingWithOptions doesn't execute, but RootViewController: viewDidLoad does

    - by BeachRunnerJoe
    I'm playing around with the iPad SplitView template and it was working fine before I started swapping out view objects in my RootViewController. When it was working fine, the application:didFinishLaunchingWithOptions method would be called and would setup my persistant store objects, then the RootViewController:viewDidLoad method would be called to populate my rootView with data from my store. I opened up IB and started swapping out view objects in my RootView and now the application:didFinishLaunchingWithOptions method never gets called, but the RootViewController:viewDidLoad method still does. Obviously, the app crashes because the viewDidLoad method depends on the successful execution of the didFinishLauchingWIthOptions method to setup the persistent store objects. Does anyone have any thoughts on what is causing this or how I can go about investigating what's causing this? I'm obviously new to iPhone OS development, so I apologize if this questions is absurd in any way. Thanks so much in advance for your help!

  • Can't make wmode: 'transparent' work on sIFR 3

    - by Synue
    I've been trying to use sIFR to change some text in my webpage. It works fine until I try to get it to use a transparent canvas. The code I'm using is as follow. I have no idea to fix it. I've seen a lot of people make this questions about wmode: 'transparent' and it all seems to work but mine. Can someone give me a hand??? Without the wmode: 'transparent' property it works fine. When I include the property it doesn't activate sIFR and we get the page as the normal HTML. sIFR.replace(myriadPro, { selector: '#title1,#title3,#title5,#title7,#title9,#title11,#title13,#title15,#title17,#title19', css: [ '.sIFR-root {background-color:none;font-size:45px;visibility:visible;text-decoration:none;color:#4C4843;cursor:pointer;}' ], wmode: 'transparent' });

  • Error: could not locate an NSManagedObjectModel for entity name 'TAB_RSS'

    - by Stephen
    Hello, Does anyone know what does the following error mean: +entityForName: could not locate an NSManagedObjectModel for entity name 'TAB_RSS' I noticed my frameworks were highlighted in red UIKIT.framework, Foundation.framework and CoreGraphics.framework. I've now added these but am getting a warning message stating "missing required architecture i386 in file". I think this may be related to the above error. I found another post that may help me http://stackoverflow.com/questions/1...e-i386-in-file but I can't find my project.pbxproj file. I think i need to edit this and remove references to the FRAMEWORK_SEARCH_PATHS. Stephen

  • MVC2 jQuery Validation & Custom Business Objects

    - by durilai
    I have an application that was built with MVC1 and am in the process of updating to MVC2. I have a custom DLL and BLL, of which the model objects are custom business objects that reside in a separate class library. I was using this validation library in MVC1, which worked great. It worked great, but I want to eliminate the extra plugins and use what is available. Rather than use the Enterprise Library validation attributes I have converted to using DataAnnotations and want to use jQuery validation as the client side validation. My questions are: 1) Is the MicrosoftMvcJQueryValidation JS file still required, where do I download. 2) How to you automate the validation to views that do not have models, IE Membership sign in page? 3) How to you add model errors in a custom business layer. Thanks for any help or guidance.

  • Disable cache in Silverlight HttpWebRequest

    - by synergetic
    My Silverlight4 app is hosted in ASP.NET MVC 2 web application. I do web request through HttpWebRequest class but it gives back a result previously cached. How to disable this caching behavior? There are some links which talks about HttpWebRequest in .NET but Silverlight HttpWebrequest is different. Someone suggested to add unique dummy query string on every web request, but I'd prefer more elegant solution. I also tried the following, but it didn't work: _myHttpWebRequest.BeginGetRequestStream(new AsyncCallback(BeginRequest), new Guid()); In fact, by setting browser history settings it is possible to disable caching. See the following link: http://stackoverflow.com/questions/3027145/asp-net-mvc-with-sql-server-backend-returns-old-data-when-query-is-executed But asking a user to change browser settings is not an option for me.

  • how secure is NSURLConnection over https

    - by drunken_elf
    I've been reading through a number of questions on this site regarding NSURLConnection and https, but most relate to "untrusted" certificates and how to allow them nonetheless. My question is a little more basic. I am building an app for a client who handle online donations, and I would like to load their donation script using an NSLURLRequest and POST the values of credit card details (entered in the app). Does NSURLConnection (when connecting to a https url) ensure the encryption of those details as they are sent to the donation script on my clients server? Sorry if this is a basic question, I just couldn't find a place in the apple docs that guaranteed this.

  • Building a blog: what's standard?

    - by Charlotte
    I'm generally pretty new at web stuff. I wanted to build a blog from scratch to get some practice. Few questions: Do most people add new entries of a blog by directly editing the html or is there a more dynamic way of doing this that is used more frequently? I'm assuming you can store the entries in some type of database and then display them via javascript or something similar? What are the most frequently used tools for what I'm describing? I know its about as simple as it gets, but like most things, I just need some tips to get started. Thanks!

  • A good machine learning technique to weed out good URLs from bad

    - by git-noob
    Hi, I have an application that needs to discriminate between good HTTP GET requests and bad. For example: http://somesite.com?passes=dodgy+parameter # BAD http://anothersite.com?passes=a+good+parameter # GOOD My system can make a binary decision about whether or not a URL is good or bad - but ideally I would like it to predict whether or not a previously unseen URL is good or bad. http://some-new-site.com?passes=a+really+dodgy+parameter # BAD I feel the need for a support vector machine (SVM) ... but I need to learn machine learning. Some questions: 1) Is an SVM appropriate for this task? 2) Can I train it with the raw URLs? - without explicitly specifying 'features' 3) How many URLs will I need for it to be good at predictions? 4) What kind of SVM kernel should I use? 5) After I train it, how do I keep it up to date? 6) How do I test unseen URLs again the SVM to decide whether it's good or bad? I
