  • What is the worst real-world macros/pre-processor abuse you've ever come across?

    - by Trevor Boyd Smith
    What is the worst real-world macros/pre-processor abuse you've ever come across (please no contrived IOCCC answers *haha*)? Please add a short snippet or story if it is really entertaining. The goal is to teach something instead of always telling people "never use macros". p.s.: I've used macros before... but usually I get rid of them eventually when I have a "real" solution (even if the real solution is inlined so it becomes similar to a macro). Bonus: Give an example where the macro was really was better than a not-macro solution. Related question: When are C++ macros beneficial?

  • Do I have to use Stored Procedures to get query level security or can I still do this with Dynamic S

    - by Peter Smith
    I'm developing an application where I'm concerned about locking down access to the database. I know I can develop stored procedures (and with proper parameter checking) limit a database user to an exact set of queries to execute. It's imperative that no other queries other then the ones I created in the stored procedures be allowed to execute under that user. Ideally even if a hacker gained access to the database connection (which only accepts connections from certain computers) they would only be able to execute the predefined stored procedures. Must I choose stored procedures for this or can I use Dynamic Sql with these fine grain permissions?

  • Making a jQuery selection in IE on html added via .load()

    - by Joel Crawford-Smith
    Scenario: I am using jQuery to lazy load some html and change the relative href attributes of all the anchors to absolute links. The loading function adds the html in all browsers. The url rewrite function works on the original DOM in all browsers. But In IE7, IE8 I can't run that same function on the new lazy loaded html in the DOM. //lazy load a part of a file $(document).ready(function() { $('#tab1-cont') .load('/web_Content.htm #tab1-cont'); return false; }); //convert relative links to absolute links $("#tab1-cont a[href^=/]").each(function() { var hrefValue = $(this).attr("href"); $(this) .attr("href", "http://www.web.org" + hrefValue) .css('border', 'solid 1px green'); return false; }); I think my question is: whats the trick to getting IE to make selections on DOM that is lazy loaded with jQuery? This is my first post. Be gentle :-) Thanks, Joel

  • Does it ever make sense to make a fundamental (non-pointer) parameter const?

    - by Scott Smith
    I recently had an exchange with another C++ developer about the following use of const: void Foo(const int bar); He felt that using const in this way was good practice. I argued that it does nothing for the caller of the function (since a copy of the argument was going to be passed, there is no additional guarantee of safety with regard to overwrite). In addition, doing this prevents the implementer of Foo from modifying their private copy of the argument. So, it both mandates and advertises an implementation detail. Not the end of the world, but certainly not something to be recommended as good practice. I'm curious as to what others think on this issue. Edit: OK, I didn't realize that const-ness of the arguments didn't factor into the signature of the function. So, it is possible to mark the arguments as const in the implementation (.cpp), and not in the header (.h) - and the compiler is fine with that. That being the case, I guess the policy should be the same for making local variables const. One could make the argument that having different looking signatures in the header and source file would confuse others (as it would have confused me). While I try to follow the Principle of Least Astonishment with whatever I write, I guess it's reasonable to expect developers to recognize this as legal and useful.

  • Creating "GDP in 1960" variable from GDP variables for different years

    - by Tom Smith
    Hi all, I'm pretty new to stata... I have a set of observations of the form "Country GDP Year". I want to create a new variable GDP1960, which gives the GDP in 1960 of each country for each year: USA $100m 1960 USA $100m 1960 $100m USA $200m 1965 --> USA $200m 1965 $100m Canada $60m 1960 Canada $60m 1960 $60m What's the right syntax to make this happen? (I assume egen is involved in some mysterious way)

  • CQRS without using others patterns

    - by John Smith
    I would like to explain CQRS to my team of developers. I just can't figure out how to explain it in the simplest way so they can implement the pattern rapidly without any others frameworks. I've read a lot of resources including video and articles but I don't find how to implement CQRS without using others patterns like a service Bus, event sourcing pattern, domain driven design. I know the purpose of these pattern but for the first step, I don't want them to think CQRS and theses patterns must be tied together. My first idea is to say that CQRS is about separating the read part and the write part. The read part is composed only of the UI project, and DAL project. Then the write part is composed of a typical multilayer architecture: UI/BLL/DAL. Then, does CQRS say we must also have two datastore ? What about the notion of commands which reveal the user's intention, is it also something part of CQRS or DDD ? Basically, how to implement CQRS without using others patterns. I concede it's also not that clear in my mind because I've used to work with NCQRS/DDD/Event Sourcing/ServiceBus in my personal project. Thanks

  • Database Structure for CakePHP Models

    - by Michael T. Smith
    We're building a data tracking web app using CakePHP, and I'm having some issues getting the database structure right. We have Companies that haveMany Sites. Sites haveMany DataSamples. Tags haveAndBelongToMany Sites. That is all set up fine. The problem is "ranking" the sites within tags. We need to store it in the database as an archive. I created a Rank model that is setup like this: rank ( id (int), sample_id (int), tag_id (int), site_id (int), rank (int), total_rows) ) So, the question is, how do I create the associations for tag, site and sample to rank? I originally set them as haveMany. But the returned structures don't get me where I'd like to be. It looks like: [Site] => Array ( [Sample] = Array(), [Tag] = Array() ) When I'm really looking for: [Site] => Array ( [Tag] = Array ( [Sample] => Array ( [Rank] => Array ( ...data... ) ) ) ) I think that I may not be structuring the database properly; so if I need to update please let me know. Otherwise, how do I write a find query that gets me where I need to be? Thanks! Thoughts? Need more details? Just ask!

  • C++ - Access array (in main) from methods outside main

    - by John Smith
    I have an array in my main class that holds objects that I need to print out for a menu listing. The array is declared and initialized in main. I need to, however, access the same array in a sub-menu function. If I copy the code (for loop that prints out the values) to the sub-menu, nothing is printed (presumably because it can't access the original array and has made a new, blank one). Is there any way (without making the array a global variable) that I can access the array in this sub-menu? Both the main and the sub-menu function are in the same file and the sub-menu is called from main. Maybe to put it more simply, can I use scope resolution to bring me up one 'level' in scope?

  • Planning a requirements gathering session using Agile

    - by Dave Smith
    We are planning on introducing Agile into our development process (a shift from the waterfall we've been using so far). We are leaning towards a hybrid model in whcih the requirements gathering session is comprised of a business analyst, subject matter experts, technical person and a user interface person. The plan is to create user stories that the development team can use in their agile process with 1 month sprints. Has anyone had experience with a hybrid model? How has it worked for you so far?

  • Using EhCache for session.createCriteria(...).list()

    - by James Smith
    I'm benchmarking the performance gains from using a 2nd level cache in Hibernate (enabling EhCache), but it doesn't seem to improve performance. In fact, the time to perform the query slightly increases. The query is: session.createCriteria(MyEntity.class).list(); The entity is: @Entity @Cache(usage = CacheConcurrencyStrategy.NONSTRICT_READ_WRITE) public class MyEntity { @Id @GeneratedValue private long id; @Column(length=5000) private String data; //---SNIP getters and setters--- } My hibernate.cfg.xml is: <!-- all the normal stuff to get it to connect & map the entities plus:--> <property name="hibernate.cache.region.factory_class"> net.sf.ehcache.hibernate.EhCacheRegionFactory </property> The MyEntity table contains about 2000 rows. The problem is that before adding in the cache, the query above to list all entities took an average of 65 ms. After the cache, they take an average of 74 ms. Is there something I'm missing? Is there something extra that needs to be done that will increase performance?

  • Could someone give me their two cents on this optimization strategy

    - by jimstandard
    Background: I am writing a matching script in python that will match records of a transaction in one database to names of customers in another database. The complexity is that names are not unique and can be represented multiple different ways from transaction to transaction. Rather than doing multiple queries on the database (which is pretty slow) would it be faster to get all of the records where the last name (which in this case we will say never changes) is "Smith" and then have all of those records loaded into memory as you go though each looking for matches for a specific "John Smith" using various data points. Would this be faster, is it feasible in python, and if so does anyone have any recommendations for how to do it?

  • Another Nim's Game Variant

    - by Terry Smith
    Given N binary sequence Example : given one sequence 101001 means player 0 can only choose a position with 0 element and cut the sequence from that position {1,101,1010} player 1 can only choose a position with 1 element ans cut the sequence from that position {null,10,101000} now player 0 and player 1 take turn cutting the sequence, on each turn they can cut any one non-null sequence, if a player k can't make a move because there's no more k element on any sequence, he lose. Assume both player play optimally, who will win ? I tried to solve this problem with grundy but i'm unable to reduce the sequence to a grundy number because it both player don't have the same option to move. Can anyone give me a hint to solve this problem ?

  • SWIG-Lua question on class returning another class

    - by John Smith
    I am concreting a question I had earlier. I have two classes in C++ and I use SWIG to wrap them. A method in one class can return a pointer to the other class. How can I get Lua to see it as more than just a userdata? More concretely: I have class fruit { int numberofseeds; //some other stuff about fruit constructors etc... public: getseedcount() { return numberofseeds; } } class tree { fruit * apple; public: //constructors and whatnot fruit * getfruit() { return apple; } } I wrap these two class with SWIG so I can access them in Lua So I can get in Lua the object x=pomona.tree(grannysmith). My question now is: How can I arrange for things so that when I type y=x:getfruit() I will get a pomona:fruit type object? Where I can write something line y:getseedcount()? At the moment all I get is userdata which not edible.

  • Facebook Like button - comment box with breif description and image

    - by Dave Smith
    On my website when the user selects the facebook like button they have the option to enter comments. This popup window to enter comments only contains the users avatar and place to enter comments. How can i include my pic and a brief description of the site directly below the comment??? At first I thought it was from the HTML title attribute or meta property="og:title" ... but populating these have no affect I have another site that contains both pic and a desc below the comment but the pic seems to be grabed at random -but always the same- from the site and the short desc I thought from the -title- attribute but its not - I changed the -title- and it still shows the same desc, its like its cached??? Any ideas how to control or populate a brief description and image within the comment section of a like button???

  • What states does my route travel through?

    - by Bert Smith
    I've got a page that has a map with a starting and ending location. I run a route between them to get the nifty line showing the route. I'm currently using Bing but have attempted with Google as well. I'd like to know which states this route passes through so I can then overlay those states with specific information. Any suggestions on how to obtain this would be most appreciated. I'm using the AJAX SDK's for both Bing and Google. Handling all the local stuff with js/jquery.

  • Should I be concerned with infected zip files?

    - by Peter Smith
    I'm writing a ASP.NET application to process user submitted zip files and limiting my extraction of files from it to only the extensions I want. I've heard of infected zip files attached to emails and I was wondering if I should be concerned about extracting data from infected zip files in my application. I don't plan on executing the content inside of the zip file, but will opening and extracting from an infected zip file cause the file to execute a virus even if I'm not executing any content inside of the zip file?

  • Is locking on the requested object a bad idea?

    - by Quick Joe Smith
    Most advice on thread safety involves some variation of the following pattern: public class Thing { private static readonly object padlock = new object(); private string stuff, andNonsense; public string Stuff { get { lock (Thing.padlock) { if (this.stuff == null) this.stuff = "Threadsafe!"; } return this.stuff; } } public string AndNonsense { get { lock (Thing.padlock) { if (this.andNonsense == null) this.andNonsense = "Also threadsafe!"; } return this.andNonsense; } } // Rest of class... } In cases where the get operations are expensive and unrelated, a single locking object is unsuitable because a call to Stuff would block all calls to AndNonsense, degrading performance. And rather than create a lock object for each call, wouldn't it be better to acquire the lock on the member itself (assuming it is not something that implements SyncRoot or somesuch for that purpose? For example: public string Stuff { get { lock (this.stuff) { // Pretend that this is a very expensive operation. if (this.stuff == null) this.stuff = "Still threadsafe and good?"; } return this.stuff; } } Strangely, I have never seen this approach recommended or warned against. Am I missing something obvious?
