• Wanted: Command line HTML5 beautifier

  - by blinry

  Wanted A command line HTML5 beautifier running under Linux. Input Garbled, ugly HTML5 code. Possibly the result of multiple templates. You don't love it, it doesn't love you. Output Pure beauty. The code is nicely indented, has enough line breaks, cares for it's whitespace. Rather than viewing it in a webbrowser, you would like to display the code on your website directly. Suspects tidy does too much (heck, it alters my doctype!), and it doesn't work well with HTML5. Maybe there is a way to make it cooperate and not alter anything? vim does too little. It only indents. I want the program to add and remove line breaks, and to play with the whitespace inside of tags. DEAD OR ALIVE!

• onchange force page submit

  - by cometta

  <form jwcid="@Form" listener="listener:updateStaff"> <select jwcid="staffselect@Select" multiple="ognl:false" validators="validators:required" onchange="this.form.submit()" listener="listener:updateStaff"> <span jwcid="@For" source="ognl:hrStaff" value="ognl:currentHrStaff" index="ognl:currentHrStaffIndex"> <option class="text11" jwcid="@Option" selected="ognl:hrStaffSelection[currentHrStaffIndex]" label="ognl:currentHrStaff"/> </span> </select> </form> when onchange on selectbox, this form will be submitted and my pageValidate() will be called follow by upadteStaff() listener method. I wonder, when such submission is fired, can onchange='' pass a flag ('selectboxisfired' string) that i able to capture inside pagevalidate() 'selectboxisfired'? this will allow my logic inside pagevalidate to indicate is triggered by selectbox.

• .NET SettingsProvider/ApplicationSettingsBase caching

  - by Andy White

  I'm looking at some code that uses the .NET System.Configuration.SettingsProvider and ApplicationSettingsBase to handle configuration. We have a class that derives from SettingsProvider that uses a database as the data store, and then we have other settings classes that inherit from ApplicationSettingsBase, and have the [SettingsProvider(typeof(MySettingsProvider))] attribute. The problem is that we're using these settings classes in multiple applications, but they seem to permanently cache the configuration values, the first time they are loaded. The issue is that if a setting is changed in one application, the other applications will not get the setting until the next restart, because they are cached everywhere. My question is: is there a way to force the SettingsProvider implementation, or the classes derived from ApplicationSettingsBase to not cache values, and re-query the datastore every time the setting is accessed? A valid answer might be that these classes were not intended to be used in multi-application environments...

• How should I use random.jumpahead in Python

  - by Peter Smit

  I have a application that does a certain experiment 1000 times (multi-threaded, so that multiple experiments are done at the same time). Every experiment needs appr. 50.000 random.random() calls. What is the best approach to get this really random. I could copy a random object to every experiment and do than a jumpahead of 50.000 * expid. The documentation suggests that jumpahead(1) already scrambles the state, but is that really true? Or is there another way to do this in 'the best way'? (No, the random numbers are not used for security, but for a metropolis hasting algorithm. The only requirement is that the experiments are independent, not whether the random sequence is somehow predictable or so)

• Insert xelements using LINQ Select?

  - by Simon Woods

  I have a source piece of xml into which I want to insert multiple elements which are created dependant upon certain values found in the original xml At present I have a sub which does this for me: <Extension()> Public Sub AddElements(ByVal xml As XElement, ByVal elementList As IEnumerable(Of XElement)) For Each e In elementList xml.Add(e) Next End Sub And this is getting invoked in a routine as follows: Dim myElement = New XElement("NewElements") myElement.AddElements( xml.Descendants("TheElements"). Where(Function(e) e.Attribute("FilterElement") IsNot Nothing). Select(Function(e) New XElement("NewElement", New XAttribute("Text", e.Attribute("FilterElement").Value)))) Is it possible to re-write this using Linq syntax so I don't need to call out to the Sub AddElements but could do it all in-line Many Thx Simon

• Separating weakly linked database schemas

  - by jldugger

  I've been tasked with revisiting a database schema we designed and use internally for various ticketing and reporting systems. Currently there exists about 40 tables in one Oracle database schema supporting perhaps six webapps. However, there's one unifying relationship amongst them all: a rooms table describing the room. Room name, purpose and other data are thrown into a shared table for each app. My initial idea was to pull each of these applications into a separate database, and perform joins between a given database and the room database. But I've discovered this solution prevents foreign key constraints in SQL Server 2005. It seems silly to duplicate one table for each app and keep those multiple copies synchronized. Should I just leave everything in one large DB, or is there something else I can do separate the tables without losing FK constraints?

• System.Drawing.Image for Images in Business Objects?

  - by Mudu

  Hi Folks I'd like to store an image in a business object. In MSDN I saw that the System.Drawing-namespace provides lots of GDI+-features, etc. Is it okay to store an Image in an System.Drawing.Image class in business layer (which is a class library "only"), and thus including a reference to System.Drawing too? I slightly feel just kind of bad doing that, 'cause it seems like I have UI-specific references in business code. Moreover, the code could become unnecessarily platform-dependant (though this is only a problem in theory, because we do not develop for multiple platforms). If it isn't right that way, which type would fit best? Thank you for any response! Matthias

• WPF TreeViewItem deselected item still lightly highlighted

  - by Patric Hua

  Hello WPF fellows, I have multiple expander controls with a ViewTree control within each expander control. When I select a ViewTreeItem from one ViewTree and then select another ViewTreeItem from another ViewTree, the newly selected ViewTreeItem is highlighted in dark blue, but the last selected item is now highlighted in a very light shade of blue. Please look at www.zunjaa.com/public/images/screen.jpg to see what I'm talking about. How do I make it so that no longer active item does not show the lighter blue? Thanks.

• How can I work around the fact that in C++, sin(3.14159265) is not 0?

  - by Adam Doyle

  In C++, const double Pi = 3.14159265; cout << sin(Pi); // displays: 3.58979e-009 it SHOULD display the number zero I understand this is because Pi is being approximated, but is there any way I can have a value of Pi hardcoded into my program that will return 0 for sin(Pi)? (a different constant maybe?) In case you're wondering what I'm trying to do: I'm converting polar to rectangular, and while there are some printf() tricks I can do to print it as "0.00", it still doesn't consistently return decent values (in some cases I get "-0.00") The lines that require sin and cosine are: x = r*sin(theta); y = r*cos(theta); BTW: My Rectangular - Polar is working fine... it's just the Polar - Rectangular Thanks! edit: I'm looking for a workaround so that I can print sin(some multiple of Pi) as a nice round number to the console (ideally without a thousand if-statements)

• Iphone video subtitles programmatic selection

  - by Marek

  I have some videos (mp4) with multiple language subtitles that can be read by an iphone. Users can select to view the subtitle and the language from the default iphone button in the video ui. I would like to be able to set a defalut programmatically, so that, for instance, an user can select a language just one time in the main screen and, from then on, all the videos will have that language subtitles on by default. I can't find anything in the official documentation. I tought about some workarounds like renaming srt files but i don't think it's possible witouht copying all the video files in the user documents dir (not an option).

• Aging Data Structure in C#

  - by thelsdj

  I want a data structure that will allow querying how many items in last X minutes. An item may just be a simple identifier or a more complex data structure, preferably the timestamp of the item will be in the item, rather than stored outside (as a hash or similar, wouldn't want to have problems with multiple items having same timestamp). So far it seems that with LINQ I could easily filter items with timestamp greater than a given time and aggregate a count. Though I'm hesitant to try to work .NET 3.5 specific stuff into my production environment yet. Are there any other suggestions for a similar data structure? The other part that I'm interested in is aging old data out, If I'm only going to be asking for counts of items less than 6 hours ago I would like anything older than that to be removed from my data structure because this may be a long-running program.

• How to assume/steal another process's windows as my own?

  - by Marco Z

  I'd like to show another app's windows under my app's taskbar button. It's a background app that reports another process's windows as my app's own. Is there any universal way to do this, e.g. each "new" window, alert glow, progressmeter, and other taskbar features, show under my own app's button? For example, Winfox runs under its own process and steals Firefox's windows. It also adds features, but that's irrelevant -- I just want to support another app's existing taskbar features under my own app's button -- multiple windows, progressmeter, alert flashing, error flashing, mini-icons, etc. Is there a near-universal way to steal an app, or is it largely app-specific? Thanks!

• Why isn't wchar_t widely used in code for Linux / related platforms?

  - by Ninefingers

  This intrigues me, so I'm going to ask - for what reason is wchar_t not used so widely on Linux/Linux-like systems as it is on Windows? Specifically, the Windows API uses wchar_t internally whereas I believe Linux does not and this is reflected in a number of open source packages using char types. My understanding is that given a character c which requires multiple bytes to represent it, then in a char[] form c is split over several parts of char* whereas it forms a single unit in wchar_t[]. Is it not easier, then, to use wchar_t always? Have I missed a technical reason that negates this difference? Or is it just an adoption problem?

• What are your build and release steps? When to increment build numbers?

  - by Ed

  I am having trouble defining and automating my build process despite simple requirements: Every build should have a unique build number. Every tagged release should be reproducible What I have: A C++, Red Hat Enterprise Linux 5.x, Subversion development environment. A build machine ( actually a virtual machine ) A version.h file with #defines for major, minor, and buildnumber. A script for incrementing the version.h buildnumber. A rpmbuild spec file that exports the tagged Subversion source, builds, and makes the rpm installer packages. Questions: Assuming multiple developers per project, when should the build number be incremented and version.h file be checked-in? The build machine? Some sort of Subversion hook? Pre-build or post-build? Thanks in advance for those willing to take the time to share their experience with build processes. -Ed Linux newbie. Former Windows C++/.NET developer.

• JSON encode MySQL results then read using jQuery

  - by silentw

  I have a database table with some rows that I want to fetch using PHP and then encode them using JSON. Currently, my database structure is the following: idcomponente | quantidade After fetching the values in PHP, I want to know how can I encode them using JSON (with multiple rows, using the same names) so I can read them using jQuery.post(). $.post('test.php',{id:id},function(data){ //READ data HERE }); Thanks in advance Edit: So far, I made this: $.post('edit/producomponentes.php',{id:id},function(data){ console.log(data); }); Logs this: [Object { componente="1", quantidade="2"}, Object { componente="3", quantidade="3"}] Now how can I go through each row and fetch their properties? (data.componente, data.quantidade)

• Mac OS date command - getting higher temporal resolution

  - by Mark

  Hey all, I am trying to use the date command in Terminal on multiple Mac OS X machines that are synced via NTP to synchronize some code in a program. Essentially I am running a program... MyProgram with arguments[date] I can get date to give me the seconds since the Unix epoch with the %M specifier. When I try to use %N to get nanosecond resolution, date just returns N. Is there anyway to get date to give me finer then second resolution? I wouldn't even mind passing two arguments such as (date +%M):arg2 And then converting units in the program. Many thanks in advance! %N specifier listed here: http://en.wikipedia.org/wiki/Date_(Unix)

• Displaying Google Calendar event data on FullCalendar

  - by aurealus

  I am using Google Calendar as a storage engine for a calendar system I am building, however, I am using a single Google user account with multiple calendars, i.e. each user on my system has their own calendar within the one user account. I'm able to create a calendar per user just fine, but I would like to have FullCalendar retrieve the events for display purposes, without manually getting the magic cookie url from Google Calendar settings. I would like to be able to retrieve it programmatically or 'proxy' the feed via an authenticated call to get event data that I'm doing in Django. $('#calendar').fullCalendar({ events: $.fullCalendar.gcalFeed( "http://www.google.com/calendar_url/" <-- or /my/event/feed/url ) });

• Best Version control for lone developer

  - by Stephen

  I'm a lone developer at the moment; please share you experiences on what is a good VC setup for a lone developer. My constraints are; I work on multiple machines and need to keep them synced up Sometimes I work offline I'm currently using Subversion(just the client to a remote server), and that is working ok. I'm interested in mecurial and git DVCS, but none of their use-cases make sense to my situation. EDIT: I've migrated my active development to Fossil http://www.fossil-scm.org/ after trialing it with a client. I really like the features to autosync my repositories(reducing accidental forks), the documentation support(both wiki and embedded/versioned) that supports my need to document the code and the project in different spaces, the easy to configure issue tracker, nice access control, skinnable web interface and helpful community.

• How to generate Doctrine models/classes that extend a custom record class

  - by Shane O'Grady

  When I use Doctrine to generate classes from Yaml/db each Base class (which includes the table definition) extends the Doctrine_Record class. Since my app uses a master and (multiple) slave db servers I need to be able to make the Base classes extend my custom record class to force writes to go to the master db server (as described here). However if I change the base class manually I lose it again when I regenerate my classes from Yaml/db using Doctrine. I need to find a way of telling Doctrine to extend my own Base class, or find a different solution to a master/slave db setup using Doctrine. Example generated model: abstract class My_Base_User extends Doctrine_Record { However I need it to be automatically generated as: abstract class My_Base_User extends My_Record { I am using Doctrine 1.2.1 in a new Zend Framework 1.9.6 application if it makes any difference.

• Android - Connectivity Questions

  - by Donal Rafferty

  I have a couple of questions about connectivity on Android, if anyone has any insight it would be great. What is the default when an application wants to wirelessly connect? Is it wlan? And if wlan is switched off or there is no access points around is it 3g or gprs? Is a device always ip connected? Or when its disabled from wlan or 3g does it lose its ip address? Is an application, for example the browser only ever connected to one ip address? Or can it be connected to multiple addresses for each radio such as gprs or wifi (wlan)? Can an application decide which connection to open a socket to? For example can I create an application and decide whether to connect the socket to the wlan or gprs? Or does the OS decide? Finally how do native applications handle connectivity? In the same manner?

• Can I use the CSS :visited pseudo class on 'wildcard' links?

  - by rabidpebble

  Let's say I have a site with multiple links as follows: www.example.com/product/1 www.example.com/product/2 www.example.com/product/3 I also append tracking info to links from time to time so that I can see how my site is being used, e.g, if somebody visits the products page from the product browser I would set a ref parameter: www.example.com/product/1&ref=pb www.example.com/product/2&ref=pb www.example.com/product/3&ref=pb The problem with this is that if the user visits a link of the first type and then views a link of the second type then the :visited pseudo class doesn't seem to apply because the browser only seems to match on exact URLs. Is there any way to have "wildcards" apply to links in this sense, so that when the user sees either the first type or the second type of link that it is highlighted? Note: I cannot change this "ref" architecture; it is inherited.

• Need help with foreach and XML

  I have the following output (via link) which displays the var_dump of some XML im generating: http://bit.ly/aoA3qY At the very bottom of the page you will see some output, generated by this code: foreach ($xml->feed as $entry) { $title = $entry->title; $title2 = $entry->entry->title; } echo $title; echo $title2; For some reason $title2 only outputs once, where there are multiple entries? Im using $xml = simplexml_load_string($data); to create the xml.

• What is it that automatically checks config changes (such as those in /etc) into git?

  - by Brandon

  I remember reading on the ubuntu forums some time ago about a program to automatically check configuration changes into version control for you. It was (of course) not Ubuntu-specific. I'm pretty sure it used git, though it may have been svn, or perhaps even able to work with multiple different VCSs. My Googling has turned up nothing, and I'd rather not roll my own script if someone has already done this well. Of course I could just manually check things in, but there are reasons I'd like it done automatically. (I'm actually planning to use this for my LastSession.plist file for Safari, so when the #@$%^*&! thing crashes, and I don't restore everything, and then Leopard crashes, the fact that it has such lousy session management won't mean I lose the dozens of windows with dozens of tabs I had open.)

• Finding the closest grid coordinate to the mouse onclick with javascript/jQuery

  - by Acorn

  What I'm trying to do is make a grid of invisible coordinates on the page equally spaced. I then want a <div> to be placed at whatever grid coordinate is closest to the pointer when onclick is triggered. Here's the rough idea: I have the tracking of the mouse coordinates and the placing of the <div> worked out fine. What I'm stuck with is how to approach the problem of the grid of coordinates. First of all, should I have all my coordinates in an array which I then compare my onclick coordinate to? Or seeing as my grid coordinates follow a rule, could I do something like finding out which coordinate that is a multiple of whatever my spacing is is closest to the onclick coordinate? And then, where do I start with working out which grid point coordinate is closest? What's the best way of going about it? Thanks!
