• Javascript string to Date conversion - simple?

  - by Mark White

  Hi all, Yesterday I managed to solve this, then lost a day's work due to the death of a HD. Now I cannot remember what I did to fix it, but I know it can be done. Input: string date in the format 'm/d/yy', eg '12/25/10', or '4/1/10' (1st April) Output - Date object I'm working with date.js and date.format.js so have Date.fromString() and Date.format() avaiable. But trying multiple combinations is not giving me what I need. IF the date were 'mm/dd/yy' then it's simple. But I'm using jquery.datepicker.js which outputs in 'm/d/yy' and I don't want to change this much I know this conversion can be done. After a 22 hour day... I need help. Thanks. Mark...

• Java : Storing Data in Array Of Object from JOptionPane Dialog

  - by Bader

  hi guys i need to know how i can insert data inside objects inside an array of objects using my already made Set methods. i need to know how should i do it through user , i mean JOptionPane input dialog [code] student[] s=new student[5]; for (int i=1 ; i <= s.length ;i++) { s[i] = new student(i,"AAA","Ecommerce",0.0); } for (int i=1; i<=s.length;i++) { name = JOptionPane.showInputDialog("Please Write Name for student n " + i); major = JOptionPane.showInputDialog("Please Write Major for student n " + i); gpa =Double.parseDouble(JOptionPane.showInputDialog("Please Write GPA for student n " +i)); s[i]=new student(i,name,major,gpa); } [/code] i tried to do vars here that get data from user by JOptionPane, but it seems that i only use my already made constructor , not the Set methods. i need to use the methods because it has some validation code inside it. any ideas ?

• Java parsing UTF8

  - by Jack

  I have the following issue with a UTF8 files structured as following: FIELD1§FIELD2§FIELD3§FIELD4 Looking at hexadecimal values of the file it uses A7 to codify §. So according to this codify it should be UTF8, but it's strange because A7 7F so 1 byte shouldn't be enough to codify §. So I tried using directly a BufferedReader with a specified charset: BufferedReader br = new BufferedReader(new InputStreamReader(new FileInputStream(input), utf8)) but when I try to tokenize the string with SmartTokenizer st = new SmartTokenizer(toTokenize, "§") (the SmartTokenizer is a modified version of the StringTokenizer that keeps empty tokens) no splitting occurs, and if I try to print the string I obtain FIELD1?FIELD2?FIELD3?... so § used in the file is different from the one specified as a the delimiter, and it's not able to print out it too. So what's the problem here? Maybe the original file should use 2 bytes to store §?

• Capture Silverlight 4 event when panel clicked

  - by Eric J.

  I have a small Silverlight 4 app that essentially consists of a grid containing a label and a combo box. When I click the label, I replace it with a second text box so that I can edit the label (much the way you can edit the name of a Silverlight control in VS2010). I have a LostFocus event handler on the text box that will end editing when the control loses focus (restoring the updated label). Trouble is, users tend to click on the panel when they are done editing rather than on another control (or hitting Enter, which is also supported). I tried adding a left mouse down event handler to the panel. However, that only fires when the text box does not have the focus (I guess the text box captured the mouse?) Is there an approach to recognize that a non-input control was clicked that would enable me to terminate edit mode?

• Match regex from right to left?

  - by Balroq

  Hi! Is there any way of matching a regex from right to left? What Im looking for is a regex that gets MODULE WAS INSERTED EVENT LOST SIGNAL ON E1/T1 LINK OFF CRC ERROR EVENT CLK IS DIFF FROM MASTER CLK SRC OF from this input CLI MUX trap received: (022) CL-B MCL-2ETH MODULE WAS INSERTED EVENT 07-05-2010 12:08:40 CLI MUX trap received: (090) IO-2 ML-1E1 EX1 LOST SIGNAL ON E1/T1 LINK OFF 04-06-2010 09:58:58 CLI MUX trap received: (094) IO-2 ML-1E1 EX1 CRC ERROR EVENT 04-06-2010 09:58:59 CLI MUX trap received: (009) CLK IS DIFF FROM MASTER CLK SRC OFF 07-05-2010 12:07:32 If i could have done the matching from right to left I could have written something like everything to right of (EVENT|OFF) until the second appearance of more than one space [ ]+ The best I managed today is to get everything from (022) to EVENT with the regex CLI MUX trap received: \([0-9]+\)[ ]+(.*[ ]+(EVENT|OFF)) But that is not really what I wanted :)

• Display a boolean model field in a django form as a radio button rather than the default Checkbox.

  - by Lakshman Prasad

  This is how I went about, to display a Boolean model field in the form as Radio buttons Yes and No. choices = ( (1,'Yes'), (0,'No'), ) class EmailEditForm(forms.ModelForm): #Display radio buttons instead of checkboxes to_send_form = forms.ChoiceField(choices=choices,widget=forms.RadioSelect) class Meta: model = EmailParticipant fields = ('to_send_email','to_send_form') def clean(self): """ A workaround as the cleaned_data seems to contain u'1' and u'0'. There may be a better way. """ self.cleaned_data['to_send_form'] = int(self.cleaned_data['to_send_form']) return self.cleaned_data As you can see in the code above, I need a clean method that converts input string to an integer, which may be unnecessary. Is there a better and/or djangoic way to do this. If so, how? And no, using BooleanField seems to cause a lot more problems. Using that seemed obvious to me; but it isn't. Why is it so.

• Microsoft SQL Server 2005 - using the modulo operator

  - by cc0

  So I have a silly problem, I have not used much SQL Server before, or any SQL for that matter. I basically have a minor mathematical problem that I need solved, and I thought modulo would be good. I have a number of dates in the database, but I need them be rounded off to the closest [dynamic integer] (could be anything from 0 to 5000000) which will be input as a parameter each time this query is called. So I thought I'd use modulo to find the remainder, then subtract that remainder from the date. If there is a better way, or an integrated function, please let me know! What would be the syntax for that? I've tried a lot of things, but I keep getting error messages like integers/floats/decimals can't be used with the modulo operators. I tried casting to all kinds of numeric datatypes. Any help would be appreciated.

• Amazon AWS s3fs mount problem on Fedora 14

  - by Alex

  I successfully compiled and installed s3fs (http://code.google.com/p/s3fs/) on my Fedora 14 machine. I included the password credentials in /etc/ as specified in the guide. When I run: sudo /usr/bin/s3fs bucket_name /mnt/bucket_name/ it runs successfully. (note: the bucket name is the same as the folder name in /mnt/). When I run ls in /mnt/ I get the error "ls: cannot access bucket_name: Permission denied". When I run sudo chmod 640 /mnt/bucket_name I get "chmod: changing permissions of `bucket_name': Input/output error". When I reboot the machine I can access the folder /mnt/bucket_name normally but it is not mapped to the s3 bucket. So, basically I have two questions. 1) How do I access the folder (/mnt/bucket_name) as usual after I mount it to the s3 bucket and 2) How can I keep it mounted even after machine restart. Regards

• How to burn an Audio CD programmatically in Mac OS X

  - by Adion

  All the info I can find about burning cd's is for Windows, or about full programs to burn cd's. I would however like to be able to burn an Audio CD directly from within my program. I don't mind using Cocoa or Carbon, or if there are no API's available to do this directly, using a command-line program that can use a wav/aiff file as input would be a possibility too if it can be distributed with my application. Because it will be used to burn dj mixes to cd, it would also be great if it is possible to create different tracks without a gap between them.

• Question on multi-probe Local Sensitive Hashing

  - by Yijinsei

  Hey guys sorry to be asking this kind noob question, but because I really need some guidance on how to use Multi probe LSH pretty urgently, so I did not do much research myself. I realize there is a lib call LSHKIT available that implemented that algorithm, but I have trouble trying to figure out how to use it. Right now, I have a few thousand feature vector 296 dimension, each representing an image. The vector is used to query an user input image, to retrieve the most similar image. The method I used to derive the distance between vector is euclidean distance. I know this might be a rather noob question, but do you guys have knowledge on how should i implement multi probe LSH? I am really very grateful to any answer or response.

• rails date field format on error

  - by ash34

  Hi, I have an input field that captures a date in my form <%= f.text_field :from_date, :style => 'width:80px;' %> The user enters the date in the following format MM/DD/YYYY. However, when there is a validation error in the model and the form is displayed back to the user with the entered values, the date format is converted to YYYY-MM-DD HH:MM:SS UTC. Where do I format this to show MM/DD/YYYY, when the form is displayed to the user. thanks.

• Is there a better way of designing zend_forms rather than using decorators?

  - by Hanseh

  Hi, I am currently using zend_decorators to add styles to my form. I was wondering if there is an alternative way of doing it? It is a bit difficult to write decorators. I would love the casual one using divs and css style : <input type="submit" class="colorfulButton" > It is much simpler rather than set a decorator for a certain control and add it. Since it requires creating a decorator for each style implementation and adding it up with the control. Will view helpers to the trick?

• Which JavaScript MVC framework to use for wysiwyg editing and floating context-sensitive settings pa

  - by ernests

  I'm developing a cms that allows editing everything on the page (generated server-side with a template engine) by just clicking on it — the area turns into input field, textarea or a full-featured tinyMCE editor, Template defines editable elements like "page heading", "copyright footer text", "image", "rich text block" etc. Along with that there's always a flotaing panel with several tabs, some of which contain general settings like page bacground color, font settings etc, but some are context sensitive (e.g., the clicking on "image" editable field triggers to display uploading/cropping/captioning interface in the floating panel). All settings in the panel are either simple inputs or sliders or checkboxes. I'm new to using MVC with javascript, and in fact haven't used it much before. jQuery is used as code library for the project. Should i use JavascriptMVC, SproutCore or anything else? Does any of them allow some kind of sandboxing (within bounds of commmon sense) to allow some javascript code by user-generated skins on my cms? thank you!

• UpdateModel prefix - ASP.NET MVC

  - by Kristoffer Ahl

  I'm having trouble with TryUpdateModel(). My form fields are named with a prefix but I am using - as my separator and not the default dot. <input type="text" id="Record-Title" name="Record-Title" /> When I try to update the model it does not get updated. If i change the name attribute to Record.Title it works perfectly but that is not what I want to do. bool success = TryUpdateModel(record, "Record"); Is it possible to use a custom separator?

• Fastest way to list all primes below N in python

  - by jbochi

  This is the best algorithm I could come up with after struggling with a couple of Project Euler's questions. def get_primes(n): numbers = set(range(n, 1, -1)) primes = [] while numbers: p = numbers.pop() primes.append(p) numbers.difference_update(set(range(p*2, n+1, p))) return primes >>> timeit.Timer(stmt='get_primes.get_primes(1000000)', setup='import get_primes').timeit(1) 1.1499958793645562 Can it be made even faster? EDIT: This code has a flaw: Since numbers is an unordered set, there is no guarantee that numbers.pop() will remove the lowest number from the set. Nevertheless, it works (at least for me) for some input numbers: >>> sum(get_primes(2000000)) 142913828922L #That's the correct sum of all numbers below 2 million >>> 529 in get_primes(1000) False >>> 529 in get_primes(530) True EDIT: The rank so far (pure python, no external sources, all primes below 1 million): Sundaram's Sieve implementation by myself: 327ms Daniel's Sieve: 435ms Alex's recipe from Cookbok: 710ms EDIT: ~unutbu is leading the race.

• Generating VS 2005 .vcproj's by hand

  - by Kevin

  I'm working on a script that generates Visual Studio 2005 C++ project files (.vcproj). The script reads a makefile, then spits out a c++ project. INPUT: makefile --- OUTPUT: VS 2005 c++ project (.vcproj) However, when I try to build the auto-generated project in VS 2005, error outputs: "Unspecified Error." Evidently, I am not generating the VS 2005 .vcproj file correctly. Assuming that my c++ project file was malformed, I opened up VS 2005 and made a new C++ project. I actually copied the good, VS 2005-created project file to my non-working, malformed project file. I replaced the Name, Reference Includes (.libs), Compile Includes (.cc, .c), etc. in the good VS 2005 project with my malformed project file's information. However, I still cannot get VS 2005 to compile my .vcproj. Perhaps VS 2005 is very particular about the content of its .vcproj's? Please give me advice on how to manually generate a VS 2005 .vcproj. Thanks!

• Autocomplete and Dynamic Parameter Passing

  - by abcParsing

  The code below works fine using jQuery UI 1.8 and jQuery 1.4.2 $("#sid_entry_box").autocomplete( {source:"autocomplete_sid.php?database="+database_name, minLength:4, delay:1000, enable:true, cacheLength:1 }); The database name is passed as a get parameter of the php call. In this application, I have two databases selected by a radio button. Since jQuery loads and assigns this function when the document is loaded, the database name is whatever was checked at that momemnt. What I really need to pass to the php call is the following: database=$("input[name=rf_database_option]:checked").val(); Is ther ean easy to understand way to be able to pass a dynamic dom value?

• Erlang Supervisor Strategy For Restarting Connections to Downed Hosts

  - by derdewey

  I'm using erlang as a bridge between services and I was wondering what advice people had for handling downed connections? I'm taking input from local files and piping them out to AMQP and it's conceivable that the AMQP broker could go down. For that case I would want to keep retrying to connect to the AMQP server but I don't want to peg the CPU with those connections attempts. My inclination is to put a sleep into the reboot of the AMQP code. Wouldn't that 'hack' essentially circumvent the purpose of failing quickly and letting erlang handle it? More generally, should the erlang supervisor behavior be used for handling downed connections?

• Data validate tools (ETL tools) for SQL server

  - by Stan

  I have some data in Excel and need to import into database. Is there any tool that can validate and maybe clean the data? Does Red Gate have such tool? The input will be Excel. Given table constraints, eg. CHECK, UNIQUE KEY, datetime format, NOT NULL. Desire output should be as least shows which lines are having problems, and then fix some trivial error automatically, like fill in default value for NULL columns, automatically correct datetime format. I know using Python can build such a script. But just wonder what's the popular way to do this. Thanks.
