• Getting Started with CacheMoney

  - by Matt Grande

  I recently installed cache-money. After some difficulties getting memcached and cache-money set up, I thought I had it working. It cached the one query on my login page fine. I login, and go to my message index page and get this error: indices delegated to @cache_config.indices, but @cache_config is nil: Slug(id: integer, name: string, sluggable_id: integer, sequence: integer, sluggable_type: string, scope: string, created_at: datetime) Searching for the first part of that error message returns 0 hits on Google, so I'm at a loss on where to even begin. Any suggestions?

• JSF 2.0: java based custom component + html table + facelets = data model not updated

  - by mikic

  Hi, I'm having problems getting the data model of a HtmlDataTable to be correctly updated by JSF 2.0 and Facelets. I have created a custom Java-based component that extends HtmlDataTable and dynamically adds columns in the encodeBegin method. @Override public void encodeBegin(FacesContext context) throws IOException { if (this.findComponent("c0") == null) { for (int i = 0; i < 3; i++) { HtmlColumn myNewCol = new HtmlColumn(); myNewCol.setId("c" + i); HtmlInputText myNewText = new HtmlInputText(); myNewText.setId("t" + i); myNewText.setValue("#{row[" + i + "]}"); myNewCol.getChildren().add(myNewText); this.getChildren().add(myNewCol); } } super.encodeBegin(context); } My test page contains the following <h:form id="fromtb"> <test:MatrixTest id="tb" var="row" value="#{MyManagedBean.model}"> </test:MatrixTest> <h:commandButton id="btn" value="Set" action="#{MyManagedBean.mergeInput}"/> </h:form> <h:outputText id="mergedInput" value="#{MyManagedBean.mergedInput}"/> My managed bean class contains the following @ManagedBean(name="MyManagedBean") @SessionScoped public class MyManagedBean { private List model = null; private String mergedInput = null; public MyManagedBean() { model = new ArrayList(); List myFirst = new ArrayList(); myFirst.add(""); myFirst.add(""); myFirst.add(""); model.add(myFirst); List mySecond = new ArrayList(); mySecond.add(""); mySecond.add(""); mySecond.add(""); model.add(mySecond); } public String mergeInput() { StringBuffer myMergedInput = new StringBuffer(); for (Object object : model) { myMergedInput.append(object); } setMergedInput(myMergedInput.toString()); return null; } public List getModel() { return model; } public void setModel(List model) { this.model = model; } public String getMergedInput() { return mergedInput; } public void setMergedInput(String mergedInput) { this.mergedInput = mergedInput; } When invoked, the page is correctly rendered with a table made of 3 columns (added at runtime) and 2 rows (as my data model has 2 rows). However when the user enter some data in the input fields and then click the submit button, the model is not correctly updated and therefore the mergeInput() method creates a sequence of empty strings which is rendered on the same page. I have added some logging to the decode() method of my custom component and I can see that the parameters entered by the user are being posted back with the request, however these parameters are not used to update the data model. If I update the encodeBegin() method of my custom component as follow @Override public void encodeBegin(FacesContext context) throws IOException { super.encodeBegin(context); } and I update the test page as follow <test:MatrixTest id="tb" var="row" value="#{MyManagedBean.model}"> <h:column id="c0"><h:inputText id="t0" value="#{row[0]}"/></h:column> <h:column id="c1"><h:inputText id="t1" value="#{row[1]}"/></h:column> <h:column id="c2"><h:inputText id="t2" value="#{row[2]}"/></h:column> </test:MatrixTest> the page is correctly rendered and this time when the user enters data and submits the form, the underlying data model is correctly updated and the mergeInput() method creates a sequence of strings with the user data. Why does the test case with columns declared in the facelet page works correctly (ie the data model is correctly updated by JSF) where the same does not happen when the columns are created at runtime using the encodeBegin() method? Is there any method I need to invoke or interface I need to extend in order to ensure the data model is correctly updated? I am using this test case to address the issue that is appearing in a much more complex component, therefore I can't achieve the same functionality using a facelet composite component. Please note that this has been done using NetBeans 6.8, JRE 1.6.0u18, GlassFish 3.0. Thanks for your help.

• MySQL replication - rapidly growing relay bin logs

• Firefox and Chrome keeps forcing HTTPS on Rails app using nginx/Passenger

  - by Steve

  I've got a really weird problem here where every time I try to browse my Rails app in non-SSL mode Chrome (v16) and Firefox (v7) keeps forcing my website to be served in HTTPS. My Rails application is deployed on a Ubuntu VPS using Capistrano, nginx, Passenger and a wildcard SSL certificate. I have set these parameters for port 80 in the nginx.conf: passenger_set_cgi_param HTTP_X_FORWARDED_PROTO http; passenger_set_cgi_param HTTPS off; The long version of my nginx.conf can be found here: https://gist.github.com/2eab42666c609b015bff The ssl-redirect.include file contains: rewrite ^/sign_up https://$host$request_uri? permanent ; rewrite ^/login https://$host$request_uri? permanent ; rewrite ^/settings/password https://$host$request_uri? permanent ; It is to make sure those three pages use HTTPS when coming from non-SSL request. My production.rb file contains this line: # Enable HTTP and HTTPS in parallel config.middleware.insert_before Rack::Lock, Rack::SSL, :exclude => proc { |env| env['HTTPS'] != 'on' } I have tried redirecting to HTTP via nginx rewrites, Ruby on Rails redirects and also used Rails view url using HTTP protocol. My application.rb file contains this methods used in a before_filter hook: def force_http if Rails.env.production? if request.ssl? redirect_to :protocol => 'http', :status => :moved_permanently end end end Every time I try to redirect to HTTP non-SSL the browser attempts to redirect it back to HTTPS causing an infinite redirect loop. Safari, however, works just fine. Even when I've disabled serving SSL in nginx the browsers still try to connect to the site using HTTPS. I should also mention that when I pushed my app on to Heroku, the Rails redirect work just fine for all browsers. The reason why I want to use non-SSL is that my homepage contains non-secure dynamic embedded objects and a non-secure CDN and I want to prevent security warnings. I don't know what is causing the browser to keep forcing HTTPS requests.

• Opera IME support

  - by Fionn

  Hi, i am currently trying to get Input Mode Editor (IME) support working with a designMode enabled IFrame. The problem here is with Opera it seems I don't get any useful notifications from the IME. It seems I get a single keydown with a keycode of 197 if the first time the IME is used - and nothing else ever again (No keycode 229 messages, no textinput event). With all other browsers keydown events with an keycode of 229 seem to be common if there is something happening in the scope of the IME. And with some goodwill and combination of keyup with keycode 13 and textinput events it seems to be possible to detect the moment the sequence is done. Thanks

• Using LINQ Group By to return new XElements

  - by Jon

  I have the following code and got myself confused: I have a query that returns a set of records that have been identified as duplicates and I then want to create a XElement for each one. This should be done in one query I think but I'm now lost. var f = (from x in MyDocument.Descendants("RECORD") where itemsThatWasDuplicated.Contains((int)x.Element("DOCUMENTID")) group x by x.Element("DOCUMENTID").Value into g let item = g.Skip(1) //Ignore first as that is the valid one select item ); var errorQuery = (from x in f let sequenceNumber = x.Element("DOCUMENTID").Value let detail = "Sequence number " + sequenceNumber + " was read more than once" select new XElement("ERROR", new XElement("DATETIME", time), new XElement("DETAIL", detail), new XAttribute("TYPE", "DUP"), new XElement("ID", x.Element("ID").Value) ) );

• NpgSQL insert file path containing backslashes "\\"

  - by Chau

  I am trying to create a record containing the path to a file. The insertion is done into a Postgres database where UTF8 is enabled, using the NpqSQL driver. My table definition: CREATE TABLE images ( id serial, file_location character varying NOT NULL ) My SQL statement (boiled down to a minimum): INSERT INTO images (file_location) VALUES (E'\\2010') When using pgAdmin to insert the above statement, it works fine. Using the NpgSQL driver through Visual Studio C#, it fails with this exception: "ERROR: 22021: invalid byte sequence for encoding \"UTF8\": 0x81" Replacing my SQL statement with the following: INSERT INTO images (file_location) VALUES (E'\\a2010') ^ The E is encouraged by pgAdmin when using double backslashes. So a quick recap: Why is NpqSQL stopping my insertion of the \\2010?

• Is "map" a loop?

  - by DVK

  While answering this question, I came to realize that I was not sure whether Perl's map can be considered a loop or not? On one hand, it quacks/walks like a loop (does O(n) work, can be easily re-written by an equivalent loop, and sort of fits the common definition = "a sequence of instructions that is continually repeated"). On the other hand, map is not usually listed among Perl's control structures, of which loops are a subset of. E.g. http://en.wikipedia.org/wiki/Perl_control_structures#Loops So, what i'm looking for is a formal reason to be convinced of one side vs. the other. So far, the former (it is a loop) sounds a lot more convincing to me, but I'm bothered by the fact that I never saw "map" mentioned in a list of Perl loops.

• Using MyGeneration, doodads, and Oracle XE, is it possible to implement an "auto number primary key"

  - by Michael Rosario

  Hello world. Using MyGeneration, doodads, and Oracle XE, is it possible to implement an "auto number primary key" scheme? Problem facts: I am using Oracle XE. I have implemented the following table and trigger: CREATE TABLE "USERS" ( "ID" NUMBER(38,0), "USER_NAME" VARCHAR2(50), "PASSWORD" VARCHAR2(50), "EMAIL" VARCHAR2(100), CONSTRAINT "USERS_PK" PRIMARY KEY ("ID") ENABLE ) / CREATE OR REPLACE TRIGGER "BI_USERS" before insert on "USERS" for each row begin select "USERS_SEQ".nextval into :NEW.ID from dual; end; / ALTER TRIGGER "BI_USERS" ENABLE / MyGeneration / Doodads created the following stored proc... CREATE OR REPLACE PROCEDURE "XXX"."PI_USERS" ( p_ID IN USERS.ID%type, p_USER_NAME IN USERS.USER_NAME%type, p_PASSWORD IN USERS.PASSWORD%type, p_EMAIL IN USERS.EMAIL%type ) IS BEGIN INSERT INTO USERS ( ID, USER_NAME, PASSWORD, EMAIL ) VALUES ( p_ID, p_USER_NAME, p_PASSWORD, p_EMAIL ); END PI_USERS; The sequence and trigger combination is working fine. The BusinessEntity class in C# does not receive the new ID. Any recommended ways to allow the calling code receive the new record ID?

• Mixing inheritance mapping strategies in NHibernate

  - by MylesRip

  I have a rather large inheritance hierarchy in which some of the subclasses add very little and others add quite a bit. I don't want to map the entire hierarchy using either "table per class hierarchy" or "table per subclass" due to the size and complexity of the hierarchy. Ideally I'd like to mix mapping strategies such that portions of the hierarchy where the subclasses add very little are combined into a common table a la "table per class hierarchy" and subclasses that add a lot are broken out into a separate table. Using this approach, I would expect to have 2 or 3 tables with very little wasted space instead of either 1 table with lots of fields that don't apply to most of the objects, or 20+ tables, several of which would have only a couple of columns. In the NHibernate Reference Documentation version 2.1.0, I found section 8.1.4 "Mixing table per class hierarchy with table per subclass". This approach switches strategies partway down the hierarchy by using: ... <subclass ...> <join ...> <property ...> ... </join> </subclass> ... This is great in theory. In practice, though, I found that the schema was too restrictive in what was allowed inside the "join" element for me to be able to accomplish what I needed. Here is the related part of the schema definition: <xs:element name="join"> <xs:complexType> <xs:sequence> <xs:element ref="subselect" minOccurs="0" /> <xs:element ref="comment" minOccurs="0" /> <xs:element ref="key" /> <xs:choice minOccurs="0" maxOccurs="unbounded"> <xs:element ref="property" /> <xs:element ref="many-to-one" /> <xs:element ref="component" /> <xs:element ref="dynamic-component" /> <xs:element ref="any" /> <xs:element ref="map" /> <xs:element ref="set" /> <xs:element ref="list" /> <xs:element ref="bag" /> <xs:element ref="idbag" /> <xs:element ref="array" /> <xs:element ref="primitive-array" /> </xs:choice> <xs:element ref="sql-insert" minOccurs="0" /> <xs:element ref="sql-update" minOccurs="0" /> <xs:element ref="sql-delete" minOccurs="0" /> </xs:sequence> <xs:attribute name="table" use="required" type="xs:string" /> <xs:attribute name="schema" type="xs:string" /> <xs:attribute name="catalog" type="xs:string" /> <xs:attribute name="subselect" type="xs:string" /> <xs:attribute name="fetch" default="join"> <xs:simpleType> <xs:restriction base="xs:string"> <xs:enumeration value="join" /> <xs:enumeration value="select" /> </xs:restriction> </xs:simpleType> </xs:attribute> <xs:attribute name="inverse" default="false" type="xs:boolean"> </xs:attribute> <xs:attribute name="optional" default="false" type="xs:boolean"> </xs:attribute> </xs:complexType> </xs:element> As you can see, this allows the use of "property" child elements or "component" child elements, but not both. It also doesn't allow for "subclass" child elements to continue the hierarchy below the point at which the strategy was changed. Is there a way to accomplish this?

• Comparing (similar) images with Python/PIL

  - by Attila Oláh

  I'm trying to calculate the similarity (read: Levenshtein distance) of two images, using Python 2.6 and PIL. I plan to use the python-levenshtein library for fast comparison. Main question: What is a good strategy for comparing images? My idea is something like: Convert to RGB (transparent - white) (or maybe convert to monochrome?) Scale up the smaller one to the larger one's size Convert each channel (= the only channel, if converted to monochrome) to a sequence (item value = color value of the pixel) Calculate the Levenshtein distance between the two sequences Of course, this will not handle cases like mirrored images, cropped images, etc. But for basic comparison, this should be useful. Is there a better strategy documented somewhere?

• C# .Net file in use issue

  - by Dan

  I'm having an issue opening files that have recently been closed by the .Net framework. Basically, what happens is the following: -Read in an XML file using DataSet.ReadXml() -Make some changes to the data -Write out the XML file using DataSet.WriteXml() -Copy the XML file to a new location using File.Copy -FTP the file using a custom control This sequence can intermittently fail either after the WriteXML or the File.Copy with a file in use exception. I'm guessing it could be the Windows write cache not flushing right away. Can anyone confirm that this could be causing my issue? Any solutions to suggest? Thanks, Dan

• Unique ID for WORD2007 paragraph

  - by Ganish

  Hello, I am writing large WORD2007 socuments, which are often being changed. I ahve to number paragraphs with stationary unique unmbers, that will not change while changing the documents. The numbers should be unique, and will not change even if previous numbers are deleted. The order of the list is not mandatory, and addition of a new number before existing numbers is possible (for instance: the sequence 1, 4, 3 means that paragraphs 1-3 were written, then #2 was deleted, then #5 was added. #3 was not affected by the later editing) The mechanism should be internal to the document, as I am working on line and off line. The numbers are allocated to every document indovidually. Since I don't know to program under WORD, I'd appreciate getting complete solution. REgards Ganish

  Hi It seems that Objective C jumps thru hoops to make seemingly simple tasks extremely difficult. I simply need to create a sequence of strings, image1.jpg, image2.jpg, etc etc ie in a loop var imgString:String='image'+i+'.jpg; I assume a best practice is to use a NSMutableString with appendString method? What am I doing wrong??

• Scala regex Named Capturing Groups

• Injecting raw TCP packets with Python

  - by Evgeniy Arbatov

  Hello! What would be a suitable way to inject a raw TCP packet with Python? For example, I have the payload consisting of hexadecimal numbers and I want to send that sequence of hexadecimal numbers to a network daemon: so that if I choose to send 'abcdef', I see 'abcdef' on the wire too. But not '6162636566' as in the case of: new = socket.socket(socket.AF_INET, socket.SOCK_STREAM) new.connect(('127.0.0.1', 9999)) new.send('abcdef') Can I use Python's SOCK_RAW for this purpose? If so, can you give me an example of sending raw TCP packets with SOCK_RAW (since I did not get it working myself) Thanks! Evgeniy

• Properly handling unicode characters in Rails

  - by Gdeglin

  By default Rails allows users of our application to input non-utf8 data, such as: ¶®«¼ However when we attempt to retrieve the data from our database and render it in a template Rails incorrectly assumes that it is in UTF-8 format and throws an error. ArgumentError: invalid byte sequence in UTF-8 What is the best way to handle this? I have seen one fix that suggested sanitizing the data in every place the user can input it. However, that would involve changing a considerable amount of code and it would strip out the characters entirely. Ideally we would want some characters converted to their UTF-8 equivalents. Our environment: Ruby: 1.9.1 Rails 2.3.5 MySql Gem: 2.8.1 This is a serious and urgent problem for us so your answers are very appreciated!

• PLT Scheme Extracting field ids from structures

  - by Steve Knight

  I want to see if I can map PLT Scheme structure fields to columns in a DB. I've figured out how to extract accessor functions from structures in PLT scheme using the fourth return value of: (struct-type-info) However the returned procedure indexes into the struct using an integer. Is there some way that I can find out what the field names were at point of definition? Looking at the documentation it seems like this information is "forgotten" after the structure is defined and exists only via the generated-accessor functions: (<id>-<field-id> s). So I can think of two possible solutions: Search the namespace symbols for ones that start with my struct name (yuk); Define a custom define-struct macro that captures the ordered sequence of field-names inside some hash that is keyed by struct name (eek).
