  • How can I add multiple filters to a XSLT for-each statement?

    - by Huuuze
    I have the following XSLT node: <xsl:for-each select="Book[title != 'Moby Dick']"> .... </xsl:for-each> However, I'd like use multiple filters in the for-each. I've tried the following, but it doesn't seem to work: <!-- Attempt #1 --> <xsl:for-each select="Book[title != 'Moby Dick'] or Book[author != 'Rowling'] "> .... </xsl:for-each> <!-- Attempt #2 --> <xsl:for-each select="Book[title != 'Moby Dick' or author != 'Rowling']"> .... </xsl:for-each>

  • Avoiding spam filters on my CentOS 5.5 64bit server?

    - by Andrew Fashion
    I run a social network on my web server, with about 15,000 members right now. My administration section let's me Mass Email all my users. Currently it uses the built in PHP mail function. What is the best way to congfigure my server to bypass spam? Can I install anything on the server? Or should I just make the social network use SMTP? The admin panel lets me choose SMTP or built-in mail function. I'm not to familiar with mailing from servers, as I usually use Aweber for my mailing, but I cannot use Aweber for this as they will not let me just import 15,000 emails. Let me know, thanks.

  • Selecting a different parent in Family Safety filters for Windows 8?

    - by Zhaph - Ben Duguid
    I've got Family Safety up and running nicely on a Windows 8 Surface, with two parent accounts and two child accounts. When one of the child accounts reaches its time limit, the user can "Ask a parent for more time". However, the next dialog doesn't allow the parents to choose which parent account to use - it always comes up with my account, and my wife can't log in to authorise. How can I allow the her account to allow more time/authorise sites etc? She can use the same Live login on our Windows 7 computers to control these settings, and is listed as a Parent on the Family Safety website.

  • Any ideas why Ettercap filters aren't seeing packet data?

    - by Bryan
    I'm using an Ettercap filter to detect a query response coming back from a particular service on a remote machine. When I see a response from the service, I'm searching through the data in the packet to see if an offset is a specific value, and if so I'm changing the value at another offset. Trouble is, when I try this on a new virtual machine I built my Ettercap filter's no longer getting any data in the DATA.data variable available to it. if(ip.proto == TCP && tcp.src == 17867) { msg("Response seen!\n"); if(DATA.data + 2 == "\0x01") { msg("Flag detected!\n"); DATA.data + 5 = 0x09; } } The filter's getting applied to the traffic because "Response seen!" messages get printed out by Ettercap. However, "Flag detected!" messages do not. I think DATA.data is indeed empty because if I change my second "if" statement to check for DATA.data == "" then the "Flag detected!" message gets printed. Any ideas why this may be happening?! Also, if this is the wrong site to be asking questions like this, please let me know. I wasn't sure if it fit better here or somewhere like superuser or serverfault. By the way, this is a cross-post from StackOverflow... I should have posted on this forum instead I think. :)

  • Is there a bug with Apache 2.2 and content filters (and maybe mod_proxy)?

    - by asciiphil
    I'm running Apache 2.2.15-29 on RHEL 6 (actually Scientific Linux 6.4) and I'm trying to set up a reverse proxy with content rewriting so all of the links on the proxied web pages are rewritten to reference the proxy host. I'm running into a problem with some of the content rewriting and I'd like to know if this is a bug or if I'm doing something wrong (and how to do it right, if applicable). I'm proxying a subdirectory on an internal host (internal.example.com/foo) onto the root of an external host (external.example.com). I need to rewrite HTML, CSS, and Javascript content to fix all of the URLs. I'm also hosting some content locally on the external host, which I don't think is a problem but I'm mentioning here for completeness. My httpd.conf looks roughly like this: <VirtualHost *:80> ServerName external.example.com ServerAlias example.com # Serve all local content directly, reverse-proxy all unknown URIs. RewriteEngine On RewriteRule ^(/(index.html?)?)?$ http://internal.example.com/foo/ [P] RewriteCond %{DOCUMENT_ROOT}%{REQUEST_FILENAME} -f [OR] RewriteCond %{DOCUMENT_ROOT}%{REQUEST_FILENAME} -d RewriteRule ^.*$ - [L] RewriteRule ^/~ - [L] RewriteRule ^(.*)$ http://internal.example.com$1 [P] # Standard header rewriting. ProxyPassReverse / http://internal.example.com/foo/ ProxyPassReverseCookieDomain internal.example.com external.example.com ProxyPassReverseCookiePath /foo/ / # Strip any Accept-Encoding: headers from the client so we can process the pages # as plain text. RequestHeader unset Accept-Encoding # Use mod_proxy_html to fix URLs in text/html content. ProxyHTMLEnable On ProxyHTMLURLMap http://internal.example.com/foo/ / ProxyHTMLURLMap http://internal.example.com/foo / ProxyHTMLURLMap /foo/ / ## Use mod_substitute to fix URLs in CSS and Javascript #<Location /> # AddOutputFilterByType SUBSTITUTE text/css # AddOutputFilterByType SUBSTITUTE text/javascript # Substitute "s|http://internal.example.com/foo/|/|nq" #</Location> # Use mod_ext_filter to fix URLs in CSS and Javascript ExtFilterDefine fixurlcss mode=output intype=text/css cmd="/bin/sed -rf /etc/httpd/fixurls" ExtFilterDefine fixurljs mode=output intype=text/javascript cmd="/bin/sed -rf /etc/httpd/fixurls" <Location /> SetOutputFilter fixurlcss;fixurljs </Location> </VirtualHost> The text/html rewriting works just fine. When I use either mod_substitute or mod_ext_filter, the external server sends the pages as Transfer-Encoding: chunked, sends all of the data, and then closes the connection without sending the final, zero-length chunk. Some HTTP clients are unhappy with this. (Chrome won't process any content sent in this way, for example, so the pages don't get CSS applied to them.) Here's a sample wget session: $ wget -O /dev/null -S http://external.example.com/include/jquery.js --2013-11-01 11:36:36-- http://external.example.com/include/jquery.js Resolving external.example.com (external.example.com)... 192.168.0.1 Connecting to external.example.com (external.example.com)|192.168.0.1|:80... connected.

  • Passing hash as values in hidden_field_tag

    - by funkymunky
    I am trying to pass some filters in my params through a form like so: hidden_field_tag "filters", params[:filters] For some reason the params get changed in the next page. For example, if params[:filters] used to be... "filters"={"name_like_any"=["apple"]} [1] ...it gets changed to... "filters"="{\"name_like_any\"=[\"apple\"]}" [2] note the extra quotations and backslashes in [2] when compared to [1]. Any ideas? I'm attempting to use this with searchlogic for some filtering, but I need it to persist when I change change objects in forms. I would prefer not to have to store it in session.

  • User Story or User Stories for this specific requirement

    - by Maximus
    I have to write a user story for a requirement that involves passing search filters to the same URI and retrieving corresponding results. I have 5 filters. I plan to write 5 different stories of type: As a URI user I can search by #filter1 so that I can retrieve results based on #filter1. And then a 6th story that involves searching one or more or all six filters in conjunction. Is this is a sensible route to take?

  • Find Knowledge Quickly

    - by Get Proactive Customer Adoption Team
    Untitled Document Get to relevant knowledge on the Oracle products you use in a few quick steps! Customers tell us that the volume of search results returned can make it difficult to find the information they need, especially when similar Oracle products exist. These simple tips show you how to filter, browse, search, and refine your results to get relevant answers faster. Filter first: PowerView is your best friend Powerview is an often ignored feature of My Oracle Support that enables you to control the information displayed on the Dashboard, the Knowledge tab and regions, and the Service Request tab based on one or more parameters. You can define a PowerView to limit information based on product, product line, support ID, platform, hostname, system name and others. Using PowerView allows you to restrict: Your search results to the filters you have set The product list when selecting your products in Search & Browse and when creating service requests   The PowerView menu is at the top of My Oracle Support, near the title You turn PowerView on by clicking PowerView is Off, which is a button. When PowerView is On, and filters are active, clicking the button again will toggle Powerview off. Click the arrow to the right to create new filters, edit filters, remove a filter, or choose from the list of previously created filters. You can create a PowerView in 3 simple steps! Turn PowerView on and select New from the PowerView menu. Select your filter from the Select Filter Type dropdown list and make selections from the other two menus. Hint: While there are many filter options, selecting your product line or your list of products will provide you with an effective filter. Click the plus sign (+) to add more filters. Click the minus sign (-) to remove a filter. Click Create to save and activated the filter(s) You’ll notice that PowerView is On displays along with the active filters. For more information about the PowerView capabilities, click the Learn more about PowerView… menu item or view a short video. Browse & Refine: Access the Best Match Fast For Your Product and Task In the Knowledge Browse region of the Knowledge or Dashboard tabs, pick your product, pick your task, select a version, if applicable. A best match document – a collection of knowledge articles and resources specific to your selections - may display, offering you a one-stop shop. The best match document, called an “information center,” is an aggregate of dynamically updated links to information pertinent to the product, task, and version (if applicable) you chose. These documents are refreshed every 24 hours to ensure that you have the most current information at your fingertips. Note: Not all products have “information centers.” If no information center appears as a best match, click Search to see a list of search results. From the information center, you can access topics from a product overview to security information, as shown in the left menu. Just want to search? That’s easy too! Again, pick your product, pick your task, select a version, if applicable, enter a keyword term, and click Search. Hint: In this example, you’ll notice that PowerView is on and set to PeopleSoft Enterprise. When PowerView is on and you select a product from the Knowledge Base product list, the listed products are limited to the active PowerView filter. (Products you’ve previously picked are also listed at the top of the dropdown list.) Your search results are displayed based on the parameters you entered. It’s that simple!

  • Can I change the filter options in the video lens?

    - by user49523
    Can I change the video options on the new dash menu? To be more precise, on the video file find menu filters, can I Add, Remove or Change what URLs can be include? If so how can I do? For example if I want to change in the filters youtube shows to YouTube comedy, how you do it? (I just installed MyUnity but from what I read and tested it won't fully work on Unity 2D, however I can change video filters using that)

  • Multiple parameters vs single parameter(object with multiple properties)

    - by Shwetanka
    I have an Entity Student with following properties - (name, joinedOn, birthday, age, batch, etc.) and a function fetchStudents(<params>). I want to fetch students based on multiple filters. In my method I have two ways to pass filters. Pass all filters as params to the method Make a class StudentCriteria with filters as fields and then pass the object of this class While working in java I always go with the second option but recently I'm working in php and I was advised to go with the first way. I am unable to figure out which way is better in maintaining the code, reusability and performance wise. Thanks.

  • How can I get Thunderbird to automatically move messages?

    - by David Heffernan
    I have Thunderbird 15. I'd like to automatically move messages from one folder to another. My mail account is an IMAP account. My Blackberry is also connected to the account and when it sends mail, it places a copy on the IMAP server in a folder named Sent Items. I'd like those messages to be moved to my Inbox automatically. By default message filters are only applied automatically to the Inbox. There is an extension to do this, Filter Subfolders, but it's only for TB3. What I have tried so far is: Use the FiltaQuilla add-on to be able to filter messages for folder name. Set the string property mail.server.default.applyIncomingFilters to true. As recommended here: http://blog.mozilla.org/bcrowder/ But I can't get these filters to run automatically. I have a suspicion that filters only run automatically for incoming mail. And these are sent items. Perhaps that's it. I just don't know. On the other hand, if I run the filters manually on that folder, it does indeed move the mail. Or perhaps the issue is that these messages are saved into the Sent Items folder marked as read. Is it possible that filters are only automatically applied to unread items? If I could install an add-in that automatically ran the message filter on my folder, that would do it. Anyway, I'm at a loss now. Any suggestions are welcome. I'm not at all wedded to using filters. I just want to find a way to get these messages moved without human interaction!

  • Linq PredicateBuilder with conditional AND, OR and NOT filters.

    - by richeym
    We have a project using LINQ to SQL, for which I need to rewrite a couple of search pages to allow the client to select whether they wish to perform an and or an or search. I though about redoing the LINQ queries using PredicateBuilder and have got this working pretty well I think. I effectively have a class containing my predicates, e.g.: internal static Expression<Func<Job, bool>> Description(string term) { return p => p.Description.Contains(term); } To perform the search i'm doing this (some code omitted for brevity): public Expression<Func<Job, bool>> ToLinqExpression() { var predicates = new List<Expression<Func<Job, bool>>>(); // build up predicates here if (SearchType == SearchType.And) { query = PredicateBuilder.True<Job>(); } else { query = PredicateBuilder.False<Job>(); } foreach (var predicate in predicates) { if (SearchType == SearchType.And) { query = query.And(predicate); } else { query = query.Or(predicate); } } return query; } While i'm reasonably happy with this, I have two concerns: The if/else blocks that evaluate a SearchType property feel like they could be a potential code smell. The client is now insisting on being able to perform 'and not' / 'or not' searches. To address point 2, I think I could do this by simply rewriting my expressions, e.g.: internal static Expression<Func<Job, bool>> Description(string term, bool invert) { if (invert) { return p => !p.Description.Contains(term); } else { return p => p.Description.Contains(term); } } However this feels like a bit of a kludge, which usually means there's a better solution out there. Can anyone recommend how this could be improved? I'm aware of dynamic LINQ, but I don't really want to lose LINQ's strong typing.

  • T-SQL - Left Outer Joins - Filters in the where clause versus the on clause.

    - by Greg Potter
    I am trying to compare two tables to find rows in each table that is not in the other. Table 1 has a groupby column to create 2 sets of data within table one. groupby number ----------- ----------- 1 1 1 2 2 1 2 2 2 4 Table 2 has only one column. number ----------- 1 3 4 So Table 1 has the values 1,2,4 in group 2 and Table 2 has the values 1,3,4. I expect the following result when joining for Group 2: `Table 1 LEFT OUTER Join Table 2` T1_Groupby T1_Number T2_Number ----------- ----------- ----------- 2 2 NULL `Table 2 LEFT OUTER Join Table 1` T1_Groupby T1_Number T2_Number ----------- ----------- ----------- NULL NULL 3 The only way I can get this to work is if I put a where clause for the first join: PRINT 'Table 1 LEFT OUTER Join Table 2, with WHERE clause' select table1.groupby as [T1_Groupby], table1.number as [T1_Number], table2.number as [T2_Number] from table1 LEFT OUTER join table2 --****************************** on table1.number = table2.number --****************************** WHERE table1.groupby = 2 AND table2.number IS NULL and a filter in the ON for the second: PRINT 'Table 2 LEFT OUTER Join Table 1, with ON clause' select table1.groupby as [T1_Groupby], table1.number as [T1_Number], table2.number as [T2_Number] from table2 LEFT OUTER join table1 --****************************** on table2.number = table1.number AND table1.groupby = 2 --****************************** WHERE table1.number IS NULL Can anyone come up with a way of not using the filter in the on clause but in the where clause? The context of this is I have a staging area in a database and I want to identify new records and records that have been deleted. The groupby field is the equivalent of a batchid for an extract and I am comparing the latest extract in a temp table to a the batch from yesterday stored in a partioneds table, which also has all the previously extracted batches as well. Code to create table 1 and 2: create table table1 (number int, groupby int) create table table2 (number int) insert into table1 (number, groupby) values (1, 1) insert into table1 (number, groupby) values (2, 1) insert into table1 (number, groupby) values (1, 2) insert into table2 (number) values (1) insert into table1 (number, groupby) values (2, 2) insert into table2 (number) values (3) insert into table1 (number, groupby) values (4, 2) insert into table2 (number) values (4) EDIT: A bit more context - depending on where I put the filter I different results. As stated above the where clause gives me the correct result in one state and the ON in the other. I am looking for a consistent way of doing this. Where - select table1.groupby as [T1_Groupby], table1.number as [T1_Number], table2.number as [T2_Number] from table1 LEFT OUTER join table2 --****************************** on table1.number = table2.number --****************************** WHERE table1.groupby = 2 AND table2.number IS NULL Result: T1_Groupby T1_Number T2_Number ----------- ----------- ----------- 2 2 NULL On - select table1.groupby as [T1_Groupby], table1.number as [T1_Number], table2.number as [T2_Number] from table1 LEFT OUTER join table2 --****************************** on table1.number = table2.number AND table1.groupby = 2 --****************************** WHERE table2.number IS NULL Result: T1_Groupby T1_Number T2_Number ----------- ----------- ----------- 1 1 NULL 2 2 NULL 1 2 NULL Where (table 2 this time) - select table1.groupby as [T1_Groupby], table1.number as [T1_Number], table2.number as [T2_Number] from table2 LEFT OUTER join table1 --****************************** on table2.number = table1.number AND table1.groupby = 2 --****************************** WHERE table1.number IS NULL Result: T1_Groupby T1_Number T2_Number ----------- ----------- ----------- NULL NULL 3 On - select table1.groupby as [T1_Groupby], table1.number as [T1_Number], table2.number as [T2_Number] from table2 LEFT OUTER join table1 --****************************** on table2.number = table1.number --****************************** WHERE table1.number IS NULL AND table1.groupby = 2 Result: T1_Groupby T1_Number T2_Number ----------- ----------- ----------- (0) rows returned

  • Java Google App Engine Datastore: 'IN' operator available on JDO query filters, as with Python?

    - by Jim Blackler
    This page describes an 'IN' operator that can be used in GAE Datastore to compare a field against a list of possible matches, not just a single value: However this is for Python. In Java (App Engine 1.2.5), trying query.setFilter("someField IN param"); on my javax.jdo.query fires a JDOUserException 'Portion of expression could not be parsed: IN param'. Is there a way this can be done?

  • How do we calculate the filters in Mel-Frequency Cepstrum Coefficients Algorithm?

    - by André Ferreira
    After calculating the FFT and with the frequency we need to do something like this: http://instruct1.cit.cornell.edu/courses/ece576/FinalProjects/f2008/pae26%5Fjsc59/pae26%5Fjsc59/images/melfilt.png We filter the frequency spectrum with those triangles. I saw that we can use distint ways to calculcate the triangles. I will make the size of the triangles equal till 1kz and after that obtained with log function. What should we do now? With the frequency spectrum and the triangles defined.. - We should filter the frequency (frequencies limited to the triangles, if goes higher only counts till the triangle limit) and calculate the value of each triangle (and after that continue the algorithm). But when does the mel conversation happens? m = 2595 log (f/700 + 1) When do we pass from frequency to mel.. Can someone guide me in the right direction plz :d

  • Why don't file type filters work properly with nsIFilePicker on Mac OSX?

    - by Eric Strom
    I am running a chrome app in firefox (started with -app) with the following code to open a filepicker: var nsIFilePicker = Components.interfaces.nsIFilePicker; var fp = Components.classes["@mozilla.org/filepicker;1"] .createInstance(nsIFilePicker); fp.init(window, "Select Files", nsIFilePicker.modeOpenMultiple); fp.appendFilter("video", "*.mov; *.mpg; *.mpeg; *.avi; *.flv; *.m4v; *.mp4"); fp.appendFilter("all", "*.*"); var res = fp.show(); if (res == nsIFilePicker.returnCancel) return; var files = fp.files; var paths = []; while (files.hasMoreElements()) { var arg = files.getNext().QueryInterface( Components.interfaces.nsILocalFile ).path; paths.push(arg); } Everything seems to work fine on Windows, and the file picker itself works on OSX, but the dropdown menu to select between file types only displays in Windows. The first filter (video in this case) is in effect, but the dropdown to select the other type never shows. Is there something extra that is needed to get this working on OSX? I have tried the latest firefox (3.6) and an older one (3.0.13) and both don't show the file type dropdown on OSX.

  • HLSL - How can I set sampler Min/Mag/Mip filters to disable all filtering/anti-aliasing?

    - by RJFalconer
    I have a tex2D sampler I want to only return precisely those colours that are present on my texture. In the event of a texel overlapping multiple colours, I want it to pick one and have the whole texel be that colour. I think to do this I want to disable mipmapping, or at least trilinear filtering of mips. sampler2D gColourmapSampler : register(s0) = sampler_state { Texture = <gColourmapTexture>; //Defined above MinFilter = None; //Controls sampling. None, Linear, or Point. MagFilter = None; //Controls sampling. None, Linear, or Point. MipFilter = None; //Controls how the mips are generated. None, Linear, or Point. //... }; My problem is I don't really understand Min/Mag/Mip filtering, so am not sure what combination I need to set these in, or if this is even what I am after. MSDN has this to say; D3DSAMP_MAGFILTER: Magnification filter of type D3DTEXTUREFILTERTYPE D3DSAMP_MINFILTER: Minification filter of type D3DTEXTUREFILTERTYPE. D3DSAMP_MIPFILTER: Mipmap filter to use during minification. See D3DTEXTUREFILTERTYPE. D3DTEXF_NONE: When used with D3DSAMP_MIPFILTER, disables mipmapping.

  • Is it possible to chain -ms-filters in CSS?

    - by Jakub Hampl
    Does anyone know of a way to chain the proprietary filter properties in CSS. For example I have a div.example and I want to give it a background gradient and a drop shadow. So I'd like to do something like this: div.example { /* gradient */ filter: progid:DXImageTransform.Microsoft.Gradient(startColorstr=#cb141e78,endColorstr=#cb1dde78); /* shadow */ filter: progid:DXImageTransform.Microsoft.dropShadow(color=00143c, offX=0, offY=3, positive=true); } Except this will of course leave only the drop shadow. Anyone know a good workaround?

  • What is the order of execution when dealing with .NET MVC 2 Action Filters?

    - by user357933
    Say I have: [Attribute1(Order=0)] public class Controller1 { [Attribute2] [Attribute3] public ActionResult Action1() { ... } } The attributes get executed in the following order: 2, 3, 1 This makes sense because attributes 2 and 3 have an order of -1 and will be executed before attribute 1 which has an explicitly set order equal to 0. Now, lets say I have: [Attribute1] [Attribute2(Order=0)] public class Controller1 { [Attribute3] public ActionResult Action1() { ... } } The attributes get executed in the following order: 1, 2, 3 Why is it that attribute 2 in this case (which has an order equal to 0) is executed before attribute 3 (which has an order equal to -1)?

  • Drupal: Whow to forward argument to block-exposed-filters results?

    - by Vlad Socaciu
    I have a typical views page displaying nodes, with a taxonomy tid receiveid as an argument through the url: cat/% Now I want to further narow the results with an exposed filter by a cck field. All goes well and for tid=10 (for instance), the filtered page url is cat/10?field_no_people_value=5 Now, when I expose the filter in a block, the argument, tid, goes away and I get cat/all?field_no_people_value=5 . Obviously, filtering by tid doesn't happen anymore. How should I get around this?
