• Is there a rake task for advancing or retreating your schema version by exactly one?

  - by user30997

  Back when migration version numbers were simply incremented as you created migrations, it was easy enough to do: rake migrate VERSION=097 rake migrate VERSION=098 rake migrate VERSION=099 rake migrate VERSION=100 ...but we now have migration numbers that are something like YYYYMMDDtimeofday. Not that this is a bad thing - it keeps the migration version collisions to a minimum - but when I have 50 migrations and want to step through them one-at-a-time, it is a hassle: rake migrate VERSION=20090129215142 rake migrate VERSION=20090129219783 ...etc. I have to have a list of all the migrations open in front of me, typing out the version numbers to advance by one. Is there anything that would have an easier syntax, like: rake migrate VERSION=NEXT or rake migrate VERSION=PREV ?

• How do I compose an existing Moose role into a class at runtime?

  - by Oesor

  Say I define an abstract My::Object and concrete role implementations My::Object::TypeA and My::Object::TypeB. For maintainability reasons, I'd like to not have a hardcoded table that looks at the object type and applies roles. As a DWIMmy example, I'm looking for something along these lines in My::Object: has => 'id' (isa => 'Str', required => 1); sub BUILD { my $self = shift; my $type = $self->lookup_type(); ## Returns 'TypeB' {"My::Object::$type"}->meta->apply($self); } Letting me get a My::Object with My::Object::TypeB role applied by doing the following: my $obj = My::Object(id = 'foo') Is this going to do what I want or am I on the entirely wrong track? Edit: I simplified this too much; I don't want to have to know the type when I instantiate the object, I want the object to determine its type and apply the correct role's methods appropriately. I've edited my question to make this clearer.

• Ruby on Rails 2.3.5: update_all failing on ActiveRecord

  - by randombits

  I'm trying to update a collection of records in my database using ActiveRecord's update_all. Enter script/console. MyModel.update_all("reserved = 1", :order => 'rand()', :limit => 1000) ActiveRecord thinks order is a column, says it's unknown and throws an exception. According to the documentation though, my syntax looks sane. This is RoR 2.3.5. When doing MyModel.update_all("reserved = 1") alone, it works just fine. Also if I do MyModel.update_all("reserved = 1", "reserve_type = 2", :order = "rand()", :limit = 1000) = 0 0 rows affected. I'm simply trying to do: UPDATE MyModel SET reserved=1, reserve_type=2 ORDER BY RAND() LIMIT 1000

• ANTLR JavaScript Target

  - by kunalsawlani

  Hello, I have been using ANTLR to generate a parser + tree grammar for a mark up language with Java target which works fine. Now I am trying to get the target in JavaScript to use it in my web browser. However, I have not been able to locate any good documentation on how to go about doing this. I am using eclipse with ANTLR IDE, and when i specify the language as JavaScript, I get the following errors. Multiple markers at this line (10): internal error: group JavaScript does not satisfy interface ANTLRCore: mismatched arguments on these templates [treeParser(grammar, name, scopes, tokens, tokenNames, globalAction, rules, numRules, bitsets, labelType, ASTLabelType, superClass, members, filterMode)] (10): internal error: java.util.NoSuchElementException: no such attribute: filterMode in template context [treeParser] If anyone could help me out with this or point me to some material which I could read about the JavaScript target with ANTLR, it would be great. Thanks

• Silverlight TabControl - Finding and selecting a TabItem from a given Control in the TabItem.

  - by David Gray Wright

  I am building a LOB application that has a main section and a TabControl with various TabItems in it. On hitting save the idea is that any fields in error are highlighted and the first field in error gets the focus. If the first, and only, field in error is on an Unselected tab the tab should then become selected and the field in error should become highlighted and have focus. But I can not get this to work. What appears to be happening is that the Unselected tab is not in the visual tree so you can't navigate back to the owning TabItem and make it the currently selected TabItem in the TabControl. Has anyone got an idea on how this can be done\achieved?

• Sub-classing TreeView in WinForms for mouse over tool tips

  - by Matt

  Ok, this is a weird one. The expected behaviour for a TreeView control is that, if ShowNodeToolTips is set to false, then, when a label for a tree node exceeds the width of the control (or, more accurately, it's right hand edge is past the right hand edge of the client area), then a tooltip is shown above the node showing the full item's text. I'd like to disable that, because the above semantic doesn't always work, depending on what the treeview is contained within. So I have rolled my own, and got the tooltips to work (and line up better than the default one!) - but I would like to be able to disable the 'default' behaviour for situations where it would work natively. So, can anyone point me in the right direction as to which message to post to the TreeView in order to disable that behaviour? I have looked at the windows control reference, but couldn't find anything that looked like it might be the one.

• MouseLeftButtonUpEvent & Bubbling in Canvas

  - by Maxim

  Hi guys, I think I'm going crazy... I have Canvas with event handlers for MouseMove & MouseLeftButtonUp. However MouseLeftButtonUp is not being fired when it happens with cursor over TextBlock that is inside canvas. (it fires just fine when I release mouse button in empty space of the canvas) I tried attaching handler via AddHandler and using regular += syntax, nothing seems to work. I tried using Canvas.CaptureMouse() but it doesnt seem to work either (CaptureMouse returns true btw). MouseLeftButtonUp just doesnt want to propagate to it's parent when it happens over TextBlock (or any other element with IsHitTestVisible = true) inside Canvas. Please help.

• treeview binding wpf cannot bind nested property in a class

  - by devnet247

  Hi all New to wpf and therefore struggling a bit. I am putting together a quick demo before we go for the full implementation I have a treeview on the left with Continent Country City structure when a user select the city it should populate some textboxes in a tabcontrol on the right hand side I made it sort of work but cannot make it work with composite objects.

• adding to json property that may or may not exist yet

• Are some data structures more suitable for functional programming than others?

  - by Rob Lachlan

  In Real World Haskell, there is a section titled "Life without arrays or hash tables" where the authors suggest that list and trees are preferred in functional programming, whereas an array or a hash table might be used instead in an imperative program. This makes sense, since it's much easier to reuse part of an (immutable) list or tree when creating a new one than to do so with an array. So my questions are: Are there really significantly different usage patterns for data structures between functional and imperative programming? If so, is this a problem? What if you really do need a hash table for some application? Do you simply swallow the extra expense incurred for modifications?

• mysql, sqlite database source code

  - by Yang

  hi guys, i know implementing database is a huge topic, but i want to have a basic understanding of how database systems works (e.g. memory management, binary tree, transaction, sql parsing, multi-threading, partitions, etc) by investigating the source code of the database, since there are a few already proven very robust open source databases like mysql, sqlite and so on. however, the code are very complicated and i have no clue where to start. also i find that the old school database textbooks are only explaining the theory, not the implementation details. Can anyone suggest how should i get started and is there any books that emphasis on the technology and techniques of building dbms used in modern database industry? Thank in advance!

• Call a void* as a function without declaring a function pointer

  - by ToxIk

  I've searched but couldn't find any results (my terminology may be off) so forgive me if this has been asked before. I was wondering if there is an easy way to call a void* as a function in C without first declaring a function pointer and then assigning the function pointer the address; ie. assuming the function to be called is type void(void) void *ptr; ptr = <some address>; ((void*())ptr)(); /* call ptr as function here */ with the above code, I get error C2066: cast to function type is illegal in VC2008 If this is possible, how would the syntax differ for functions with return types and multiple parameters?

• Counting number of children in hierarchical SQL data

  - by moontear

  for a simple data structure such as so: ID parentID Text Price 1 Root 2 1 Flowers 3 1 Electro 4 2 Rose 10 5 2 Violet 5 6 4 Red Rose 12 7 3 Television 100 8 3 Radio 70 9 8 Webradio 90 For reference, the hierarchy tree looks like this: ID Text Price 1 Root |2 Flowers |-4 Rose 10 | |-6 Red Rose 12 |-5 Violet 5 |3 Electro |-7 Television 100 |-8 Radio 70 |-9 Webradio 90 I'd like to count the number of children per level. So I would get a new column "NoOfChildren" like so: ID parentID Text Price NoOfChildren 1 Root 8 2 1 Flowers 3 3 1 Electro 3 4 2 Rose 10 1 5 2 Violet 5 0 6 4 Red Rose 12 0 7 3 Television 100 0 8 3 Radio 70 1 9 8 Webradio 90 0 I read a few things about hierarchical data, but I somehow get stuck on the multiple inner joins on the parentIDs. Maybe someone could help me out here. moon

• Do passwords used for .htaccess need to be encrypted?

  - by webworm

  I am using .htaccess files to control access to various Apache2 directories. I have a main "password" file that contains usernames and passwords. All the instructions I have found regarding .htaccess talk about how the passwords added are encrypted. The usernames and passwords are created using the following command line syntax ... htpasswd -nb username password What I am wondering is ... do the passwords always need to be encrypted? Could I store usernames and passwords in a plain-text form someonewhere on the system (above the web root)? This would allow me to easily edit user names and passwords via FTP without requiring access to the Shelll (which I do not always have). Thank you.

• asp.net mvc - bootstrapping object via model binder

  - by csetzkorn

  Hi, I have a domain object Thing which can contain several Categories. So I have implemented my HTML helper to create a checkbox group of all possible Categories. I have no problem receiving: [AcceptVerbs(HttpVerbs.Post)] public ActionResult Create(Thing Thing, List<string> Categories) However I am wondering whether I could use a custom Model binder to use just this: [AcceptVerbs(HttpVerbs.Post)] public ActionResult Create(Thing Thing) So basically I am looking for a way to use the model binder to bootstrap the object tree/graph. Any pointers appreciated. Thanks. Christian

• how does ` cat << EOF` work in bash?

  - by hasen j

  I needed to write a script to enter multi-line input to a program (psql) After a big of googling, I found the following syntax works: cat << EOF | psql ---params BEGIN; `pg_dump ----something` update table .... statement ...; END; EOF This correctly concatenates all these strings and passes the result as an input to psql. but I have no idea how/why it works, can some one please explain? I'm referring mainly to cat << EOF, I know > outputs to a file, >> appends to a file, < reads input from file. What does << exactly do? And is there a man page for it?

• Git: can't undo local changes (error: path ... is unmerged)

  I have following working tree state $ git status foo/bar.txt # On branch master # Unmerged paths: # (use "git reset HEAD <file>..." to unstage) # (use "git add/rm <file>..." as appropriate to mark resolution) # # deleted by us: foo/bar.txt # no changes added to commit (use "git add" and/or "git commit -a") File foo/bar.txt is there and I want to get it to the "unchanged state" again (similar to 'svn revert'): $ git checkout HEAD foo/bar.txt error: path 'foo/bar.txt' is unmerged $ git reset HEAD foo/bar.txt Unstaged changes after reset: M foo/bar.txt Now it is getting confusing: $ git status foo/bar.txt # On branch master # Changes to be committed: # (use "git reset HEAD <file>..." to unstage) # # new file: foo/bar.txt # # Changed but not updated: # (use "git add <file>..." to update what will be committed) # (use "git checkout -- <file>..." to discard changes in working directory) # # modified: foo/bar.txt # The same file in both sections, new and modified?

• What's the right way to calculate derived data in a Flex AdvancedDataGrid using summaries?

  - by Chris R

  Here's the gist of the problem: I have a set of rows of data with (say) field1 to field4 in them. I'm using a GroupingCollection to group on field1 and field2. So, I have something like this: f1.1 f2.1 f3.1 f4.1 f3.2 f4.2 f2.2 f3.3 f4.3 f3.4 f4.4 f3.5 f4.5 f1.2 f2.1 f3.6 f4.6 f2.2 f3.7 f4.7 f3.8 f4.8 f3.9 f4.9 (or at least, I hope that's clear enough) I need to calculate some derived values for each leaf row, for example f3, that is the ratio of f3 to the average of all f3 in that particular part of the tree. So, for f3.7 I need to calculate f3.7 / avg(f3.7..f3.9) and fill that into the f3_index property on the row, displaying that in lieu of f3 itself. So, basically, what it looks like I have to do is add source field values in the summarizeFunction implementation. It seems to me that there must be a better way of doing this. Is there?

• mtl, transformers, monads-fd, monadLib, and the paradox of choice

  - by yairchu

  Hackage has several packages for monad transformers: mtl: Monad transformer library transformers: Concrete functor and monad transformers monads-fd: Monad classes, using functional dependencies monads-tf: Monad classes, using type families monadLib: A collection of monad transformers. mtl-tf: Monad transformer library using type families mmtl: Modular Monad transformer library mtlx: Monad transformer library with type indexes, providing 'free' copies. compose-trans: Composable monad transformers (and maybe I missed some) Which one shall we use? mtl is the one in the Haskell Platform, but I keep hearing on reddit that it's uncool. But what's bad about choice anyway, isn't it just a good thing? Well, I saw how for example the authors of data-accessor had to make all these to cater to just the popular choices: data-accessor-monadLib library: Accessor functions for monadLib's monads data-accessor-monads-fd library: Use Accessor to access state in monads-fd State monad class data-accessor-monads-tf library: Use Accessor to access state in monads-tf State monad type family data-accessor-mtl library: Use Accessor to access state in mtl State monad class data-accessor-transformers library: Use Accessor to access state in transformers State monad I imagine that if this goes on and for example several competing Arrow packages evolve, we might see something like: spoonklink-arrows-transformers, spoonklink-arrows-monadLib, spoonklink-tfArrows-transformers, spoonklink-tfArrows-monadLib, ... And then I worry that if spoonklink gets forked, Hackage will run out of disk space. :) Questions: Why are there so many monad transformer packages? Why is mtl [considered] uncool? What are the key differences? Most of these seemingly competing packages were written by Andy Gill and are maintained by Ross Paterson. Does this mean that these packages are not competing but rather work together in some way? And do Andy and Ross consider any of their own packages as obsolete? Which one should me and you use?

• Implementation of a general-purpose object structure (property bag)

  - by Thomas Wanner

  We need to implement some general-purpose object structure, much like an object in dynamic languages, that would give us a possibility of creating the whole object graph on-the-fly. This class has to be serializable and somehow user friendly. So far we have made some experiments with class derived from Dictionary<string, object> using the dot notation path to store properties and collections in the object tree. We have also find an article that implements something similar, but it doesn't seem to fit completely into our picture either. Do you know about some good implementations / libraries that deal with a similar problem or do you have any (non-trivial) ideas that could help us with our own implementation ? Also, I probably have to say that we are using .NET 3.5, so we can't take advantage of the new features in .NET 4.0 like dynamic type etc. (as far as I know it's also not possible to use any subset of it in .NET 3.5 solution).

• javascript regex: match altered version of first match with only one expression

  - by theseion

  Hi there I'm writing a brush for Alex Gorbatchev's Syntax Highlighter to get highlighting for Smalltalk code. Now, consider the following Smalltalk code: aCollection do: [ :each | each shout ] I want to find the block argument ":each" and then match "each" every time it occurrs afterwards (for simplicity, let's say every occurrence an not just inside the brackets). Note that the argument can have any name, e.g. ":myArg". My attempt to match ":each": \:([\d\w]+) This seems to work. The problem is for me to match the occurrences of "each". I thought something like this could work: \:([\d\w]+)|\1 but the right hand side of the alternation seems to be treated as an independent expression, so backreferencing doesn't work. So my question is: is it even possible to accomplish what I want in a single expression? Or would I have to use the backreference within a second expression (via another function call)? Cheers.

• Teach Perl as a first language?

  - by yossale

  I need to teach a non-programmer the basics of computer programming + some basic programming skills (- He's going to be in a position between the clients and the programmers , so the company requires him to learn the basic concepts of programming). I thought of Perl - You can teach it without getting into typing and pointers and it's syntax is very close to human (precious "bless" :) ) - but I'm a bit troubled because I feel like I'm going to "spoil" him for other languages in the future (C,C++,Java - What some people call "Real" languages) - exactly because of the reasons mentioned above. What do you think?

• if_attribute on declarative authorization. STUCK FOR DAYS!!!

  - by Victor Martins

  I can't seem to find a solution for this problem :s I have a many to many relationship like this: A user has_many organizations through affiliations and vice versa. I'm using declarative organizations and I only want a user to edit a particular organization if he is affiliated and the affiliationtype attribute of affiliation is a particular value. So affiliations has 3 columns , user_id, organization_id and affiliationtype_id I can do: o = Organization.find(:first) o.affiliatons[0].user and get the user now I wish to do this: has_permission_on [:organizations], :to => :edit do if_attribute (...) end That if_attribute should see if the current user is the organization.affiliation[?].user and if the organization.affiliation[?].affiliationtype_id = "3" I hope this is syntax issue ... I really need to get this working. Thanks in advance.

• Getting libjpeg/libTIFF.dylib error after recompiling php in OS X 10.6.3 Server

  I've recompiled php 5.3.0 under OS X Server (10.6.3) in order to gain Freetype support in GD. As part of the process, I recompiled libjpeg-8a (and before that I tried libjpeg-7). But when I run apachectcl configtest, I get the following error: httpd: Syntax error on line 155 of /private/etc/apache2/httpd.conf: Cannot load /usr/libexec/apache2/mod_auth_user_host_apple.so into server: dlopen(/usr/libexec/apache2/mod_auth_user_host_apple.so, 10): Symbol not found: __cg_jpeg_resync_to_restart\n Referenced from: /System/Library/Frameworks/ApplicationServices.framework/Versions/A/Frameworks/ImageIO.framework/Versions/A/Resources/libTIFF.dylib\n Expected in: /usr/lib/libJPEG.dylib\n in /System/Library/Frameworks/ApplicationServices.framework/Versions/A/Frameworks/ImageIO.framework/Versions/A/Resources/libTIFF.dylib I don't really understand the error.
