  • MySQL doesn't use index in join query

    - by Kocsonya Laci
    I have two tables: comments(id(primary key), author, ip(index)) and visitors(id(primary key), date_time, ip(index)) I want to join them like that: SELECT visitors.date_time FROM comments LEFT JOIN visitors ON ( comments.ip = visitors.ip ) WHERE comments.author = 'author' LIMIT 10 It works, but very slow.. In EXPLAIN it shows that it doesn't use the index on the visitors table: id select_type table type possible_keys key key_len ref rows Extra 1 SIMPLE comments ref author author 78 const 9660 Using where 1 SIMPLE visitors ALL NULL NULL NULL NULL 8033 Any ideas? Thanks!

  • What's the difference between <% and <%:

    - by Blub
    Hi, I couldn't find anything through Google, I suppose the search terms are too much to handle. The VS built-in help only explains <%, which is just embedded code. There is no mention of <%: EDIT: My book says, that the only difference is that <%: returns a MvcHtmlString. Why do we need an extra symbol for <%: just to return something? Thanks for any help! It would really help me to understand asp.net.

  • RoR - Associations into practise - forms (View)

    - by NicoJuicy
    I'm learning Ruby on Rails. I'm using some associations (has_many :through, ...) But i'm having some problems with it when i'm combining my views. How exactly do i combine these nested forms? Can i do this with partial forms and where do i have to write extra code for this? I have seen examples only use the "view" and others also edit the controller.... An example would be very nice :-)

  • SSL socket connection on iPhone

    - by kevinspacy
    Is there a way to reuse SSL socket connections on the iPhone. I'm seeing an extra 3-4 second overhead in doing SSL handshaking. I'm using NSURLconnection currently to do the API calls and each one of them is taking 4-5 seconds on Wifi. Any suggestions would be greatly appreciated.

  • sifr menu list problems, height of object calculated wrong

    - by armyofda12mnkeys
    I am using Drupal and have sifr set on list items, and also a, a:hover are set via Drupal so that the links hover. I looked at the sifr3-rules.js file drupal's render module creates and it looks good. and in fact my other sifr items look fine... But the list item ones are goofing for some reason... There is extra space below the list, so if i have a list item, and inside of that, I have a unordered list with more list items, the Flash Object made in the 1st li (which will cover the rest of the sublist items too), is too bid so you see space under the children until the next parent li comes up. (so looks like extra bottom padding on that portion of the list in IE8... in FF almost similar but each subitem has space at bottom... with javascript turned off, you see the list items look fine by themselves).... Also if the parent list item is shorter than the sub list items text, the width for the flash object is set only as long as the first list item, and therefore cuts off the rest the sublist item's text. Any idea how to resolve any of these? Only unusual thing i see i am doing is setting forceSingleLine and preventWrap (which dont make a difference if taken off). ****Edit, I may just try to figure out how to get Drupal's menu-block module to output a around my hyperlinks in the list items... then i can target the div's with my rule (and the a,a:hover rules will apply), so each menu item gets its own sifr object instead of sifr3 trying to figure out how to do the lists and sublists. Very useful to me is anyone knows a way to target a hyperlink (<a> tag) and also allow a:hover rules. I know how to do it with pretend another tag that includes hyperlinks, like if i had <h2><a>sometitle</a></h2>, i could have a rule for h2, but then use the a, a:hover rules in the sifr3-rules.js file to target that. so i would need a way to target the hyperlink in the list, but also apply a :hover to it (not sure if this can be done since its not underneith for example the h2 tag).

  • How to do your best when everybody is too busy?

    - by Francisco Garcia
    Sometimes I have seen some code or part of the project which I could improve but is not related with my current team project. Those times I have a conflict because despite wanting to help, many teams lack enough people and doing extra work seems like betrayal. Obviously any managers will appreciate much more if you focus your effort on their tasks What do you do in in these cases?

  • Problem solving/ Algorithm Skill is a knack or can be developed with practice?

    - by KaluSingh Gabbar
    Every time I start a hard problem and if can not figure out the exact solution or can not get started, I get into this never ending discussion with myself, as below: That problem solving/mathematics/algorithms skills are gifted (not that you can learn by practicing, by practice, you only master the kind of problems that you already have solved before) only those who went to good schools can do it, as they learned it early. What are your thoughts, can one achieve awesomeness in problem solving/algorithms just by hard work or you need to have that extra-gene in you?

  • Why is cakephp form input stored in $this->data and POST data stored in $this->params['form'] ?

    - by spudnik1979
    the cakephp rest tutorial says that post data should be in $this-data, but I am finding that it is not, but instead inside $this-params['form'] However, when using cakephp form helper in a view, the data is in $this-data. Am I correct to have to check both locations in my controller? It just seems a bit of a waste of extra code. Shouldnt the data appear in one place for whether it came from a rest rest requestor or Cakephp form post? ps im using cakephp 1.3

  • Which PHP framework is closest to Ruby on Rails? CakePHP? CodeIgniter?

    - by Mike Duncan
    I'm going to be switching back and forth between Ruby on Rails projects and some as-of-yet undecided PHP MVC framework projects. Which of the PHP MVC frameworks out there (CakePHP, CodeIgniter?, others?) is most similar to Ruby on Rails in that the most conventions, locations, workflows, etc are preserved? I'm looking for the similarity in the way things are done such as directory structures, conventions, etc, not a pros vs cons in speed, extra features, etc.

  • Is it a good or bad practice to call instance methods from a java constructor?

    - by Steve
    There are several different ways I can initialize complex objects (with injected dependencies and required set-up of injected members), are all seem reasonable, but have various advantages and disadvantages. I'll give a concrete example: final class MyClass { private final Dependency dependency; @Inject public MyClass(Dependency dependency) { this.dependency = dependency; dependency.addHandler(new Handler() { @Override void handle(int foo) { MyClass.this.doSomething(foo); } }); doSomething(0); } private void doSomething(int foo) { dependency.doSomethingElse(foo+1); } } As you can see, the constructor does 3 things, including calling an instance method. I've been told that calling instance methods from a constructor is unsafe because it circumvents the compiler's checks for uninitialized members. I.e. I could have called doSomething(0) before setting this.dependency, which would have compiled but not worked. What is the best way to refactor this? Make doSomething static and pass in the dependency explicitly? In my actual case I have three instance methods and three member fields that all depend on one another, so this seems like a lot of extra boilerplate to make all three of these static. Move the addHandler and doSomething into an @Inject public void init() method. While use with Guice will be transparent, it requires any manual construction to be sure to call init() or else the object won't be fully-functional if someone forgets. Also, this exposes more of the API, both of which seem like bad ideas. Wrap a nested class to keep the dependency to make sure it behaves properly without exposing additional API:class DependencyManager { private final Dependency dependency; public DependecyManager(Dependency dependency) { ... } public doSomething(int foo) { ... } } @Inject public MyClass(Dependency dependency) { DependencyManager manager = new DependencyManager(dependency); manager.doSomething(0); } This pulls instance methods out of all constructors, but generates an extra layer of classes, and when I already had inner and anonymous classes (e.g. that handler) it can become confusing - when I tried this I was told to move the DependencyManager to a separate file, which is also distasteful because it's now multiple files to do a single thing. So what is the preferred way to deal with this sort of situation?

  • Solution Output Directory

    - by L.E.O
    The project that I'm currently working on is being developed by multiple teams where each team is responsible for different part of the project. They all have set up their own C# projects and solutions with configuration settings specific to their own needs. However, now we need to create another, global solution, which will combine and build all projects into the same output directory. The problem that I have encountered though, is that I have found only one way to make all projects build into the same output directory - I need to modify configurations for all of them. That is what we would like to avoid. We would prefer that all these projects had no knowledge about this "global" solution. Each team must retain possibility to work just with their own sub-solution. One possible workaround is to create a special configuration for all projects just for this "global" solution, but that could create extra problems since now you have to constantly sync this configuration settings with the regular one, used by that specific team. Last thing we want to do is to spend hours trying to figure out why something doesn't work when building under global solution just because of some check box that developers have checked in their configuration, but forgot to do so in the global configuration. So, to simplify, we need some sort of output directory setting or post build event that would only be present when building from that global, all-inclusive solution. Is there any way to achieve this without changing something in projects configurations? Update 1: Some extra details I guess I need to mention: We need this global solution to be as close as possible to what the end user gets when he installs our application, since we intend to use it for debugging of the entire application when we need to figure out which part of the application isn't working before sending this bug to the team working on that part. This means that when building under global solution the output directory hierarchy should be the same as it would be in Program Files after installation, so that if, for example, we have Program Files/MyApplication/Addins folder which contains all the addins developed by different teams, we need the global solution to copy the binaries from addins projects and place them in the output directory accordingly. The thing is, the team developing an addin doest necessary know that it is an addin and that it should be placed in that folder, so they cannot change their relative output directory to be build/bin/Debug/Addins.
