• converting Date object to TimeWithZone

  - by avaynshtok

  I need to convert a Date object into a TimeWithZone object representing the beginning of that day in a given time zone. The following approach works, but seems too convoluted as it requires me to convert the date to a string: ?> date = Date.parse("2010-02-17") => Wed, 17 Feb 2010 >> ActiveSupport::TimeZone['Eastern Time (US & Canada)'].parse(date.to_s) => Wed, 17 Feb 2010 00:00:00 EST -05:00 >> ActiveSupport::TimeZone['UTC'].parse(date.to_s) => Wed, 17 Feb 2010 00:00:00 UTC 00:00 Is there a better way I'm missing?

• Create date efficiently

  - by Dave Jarvis

  On Pavel's page is the following function: CREATE OR REPLACE FUNCTION makedate(year int, dayofyear int) RETURNS date AS $$ SELECT (date '0001-01-01' + ($1 - 1) * interval '1 year' + ($2 - 1) * interval '1 day'):: date $$ LANGUAGE sql; I have the following code: makedate(y.year,1) What is the fastest way in PostgreSQL to create a date for January 1st of a given year? Pavel's function would lead me to believe it is: date '0001-01-01' + y.year * interval '1 year' + interval '1 day'; My thought would be more like: to_date( y.year||'-1-1', 'YYYY-MM-DD'); Am looking for the fastest way using PostgreSQL 8.4. (The query that uses the date function can select between 100,000 and 1 million records, so it needs speed.) Thank you!

• Tips for adapting Date table to Power View forecasting #powerview #powerbi

  - by Marco Russo (SQLBI)

  During the keynote of the PASS Business Analytics Conference, Amir Netz presented the new forecasting capabilities in Power View for Office 365. I immediately tried the new feature (which was immediately available, a welcome surprise in a Microsoft announcement for a new release) and I had several issues trying to use existing data models. The forecasting has a few requirements that are not compatible with the “best practices” commonly used for a calendar table until this announcement. For example, if you have a Year-Month-Day hierarchy and you want to display a line chart aggregating data at the month level, you use a column containing month and year as a string (e.g. May 2014) sorted by a numeric column (such as 201405). Such a column cannot be used in the x-axis of a line chart for forecasting, because you need a date or numeric column. There are also other requirements and I wrote the article Prepare Data for Power View Forecasting in Power BI on SQLBI, describing how to create columns that can be used with the new forecasting capabilities in Power View for Office 365.

• Containers of reference_wrappers (comparison operators required?)

  - by kloffy

  If you use stl containers together with reference_wrappers of POD types, the following code works just fine: int i = 3; std::vector< boost::reference_wrapper<int> > is; is.push_back(boost::ref(i)); std::cout << (std::find(is.begin(),is.end(),i)!=is.end()) << std::endl; However, if you use non-POD types such as (contrived example): struct Integer { int value; bool operator==(const Integer& rhs) const { return value==rhs.value; } bool operator!=(const Integer& rhs) const { return !(*this == rhs); } }; It doesn't suffice to declare those comparison operators, instead you have to declare: bool operator==(const boost::reference_wrapper<Integer>& lhs, const Integer& rhs) { return boost::unwrap_ref(lhs)==rhs; } And possibly also: bool operator==(const Integer& lhs, const boost::reference_wrapper<Integer>& rhs) { return lhs==boost::unwrap_ref(rhs); } In order to get the equivalent code to work: Integer j = { 0 }; std::vector< boost::reference_wrapper<Integer> > js; js.push_back(boost::ref(j)); std::cout << (std::find(js.begin(),js.end(),j)!=js.end()) << std::endl; Now, I'm wondering if this is really the way it's meant to be done, since it seems impractical. It just seems there should be a simpler solution, e.g. templates: template<class T> bool operator==(const boost::reference_wrapper<T>& lhs, const T& rhs) { return boost::unwrap_ref(lhs)==rhs; } template<class T> bool operator==(const T& lhs, const boost::reference_wrapper<T>& rhs) { return lhs==boost::unwrap_ref(rhs); } There's probably a good reason why reference_wrapper behaves the way it does (possibly to accomodate non-POD types without comparison operators?). Maybe there already is an elegant solution and I just haven't found it.

• Custom calendar drag drop event: Find date dropped to

  - by cpf

  Hi stackoverflow, I've been working in silverlight to do a date-oriented application. I started off with changing the calendar template to contain a listbox on every date, and I created a listbox containing simple items. I implemented an easy drag drop on both those elements, so now I can drag from the listbox containing the items to the listbox on a date and have an event. Downside is: In the event, I don't know which date it was dropped to. How can I figure this out? Please note: The date dropped to is not necessarily the date currently selected...

• Jquery Datepicker not selecting the default date

  - by Chirantan

  I have my datepicker set up like this $("#scheduled_date_163").datepicker({ onSelect: function(dateText, inst) { jQuery.get("/tasks/inplace_edit?id=scheduled_date_163&class_name=Task&value=" + dateText, function(data){ $('#scheduled_date_163').html(data); $('#scheduled_date_163').removeClass('hasDatepicker'); }) } }); $('#scheduled_date_163').datepicker( "option", "defaultDate", $.datepicker.parseDate("d m y", "31 8 2009") ); As you can see the date is hardcoded. It is supposed to be replaced with some code. However, the datepicker refuses to pick the date up! It always shows me the current date. Unable to figure out why. I even tried giving the date in string and +7 etc. But today's date itself is shown as the default date. What could be causing this?

• Opening images sorted by modification date/size/type/etc

  - by menino bolinho

  Suppose I have a folder with pictures in them. If I sort them by name once I open one with Image Viewer and navigate to the others the order is respected. But if I sort my files by modification date, for example, I can't do that. Basically, the default Image Viewer only lets you navigate images by name. According to this post on the ubuntuforums this has been an issue since 2007! Is there a good/easy way to fix it? Seems like such a trivial thing to me.

• No date/time shown before my page in Google search results

  - by Ruut

  I know that by changing the meta description of my webpage, I can control the texts shown by Google in the search results. However I do not know how I can control the text shown just before the search results, for example the date when the page was last updated. Which meta tag to use to accomplish this? UPDATE: My webpage is automatically updated on a weekly basis on irregular intervals by a cronjob which makes changes to the MySQL database which holds the content of my webpages. So the question is what (meta) info to add to my page.

• Resources for up-to-date Delphi programming

  - by Dan Kelly

  I'm a developer in a small department and have been using Delphi for the last 10 years. Whilst I've tried to keep up-to-date with movements there are a lot of changes that have occurred between Delphi 7 and (current for us) 2010. Stack Exchange and here have been great for answering the "how do you" questions, but what I'd like is a resource that shows great examples of larger scale programming. For example is there anywhere that hosts examples of well written, multi form applications? Something that can be looked at as a whole to illustrate why things should be done a certain way?

• Drupal Views how to filter items overlapping a date range

  - by Marcos Buarque

  Hi, in Drupal I have used CCK to add a datetime field to my custom data type. It inserts start date and end date fields. That is what I want. Now, I want Views to filter and show only the items that have the daterange (start date and end date) overlapping today's date. Any ideas on how to set it up on Views? What I think is strange is that the date fields of my custom content type don't seem to appear on the Views list when I am trying to add a filter. Thanks.

• OpenGL Learning Material (that's up to date)

  - by Sauron

  So im sure there are topics on this, but alot of them list older material. And the last book: http://www.amazon.com/OpenGL-SuperBible-Comprehensive-Tutorial-Reference/dp/0321712617/ref=sr_1_1?ie=UTF8&qid=1346116133&sr=8-1&keywords=opengl REALLY REALLY disappointed me. I DO NOT want to use someone else's library to learn this stuff, that bothers me SOOO much. So I was hoping there was a newer book that goes into detail, and doesn't use some sort of library "Hiding" everything from you. Or should I just look at older material? If so....anything thats not "too" out of date. Terrain tutorials are a plus (that's kinda my "goal"). Thanks

  Hi, I want to insert a date having this format MM/dd/YYYY for example:04/29/2010 to 29/04/2010 to be inserted into mysql database in a field typed Date. So i have this code: String dateimput=request.getParameter("datepicker"); DateFormat df = new SimpleDateFormat("dd/MM/yyyy"); Date dt = null; try { dt = df.parse(dateimput); System.out.println("date imput is:" +dt); } catch (ParseException e) { e.printStackTrace(); } but it gives me those error: 1-date imput is:Fri May 04 00:00:00 CEST 2012 (it is not the correct value that have been entered). 2-dismatching with mysql date type. I can not detect the error exactly. Please help.

• Active record taking Date.today as yesterday

  - by Mongus Pong

  I have a strange one.. I am doing something like : tip = find (:first, :conditions => ["last_shown = ? or last_shown is null", Date.today]) And then a little later on I do : tip.last_shown = Date.today tip.save When I look at output of these queries, ActiveRecord is doing the first query with todays date as I would expect. However, the send query, ActiveRecord is setting the last_shown date to be yesterdays date. Why on earth would it do this? I have config.time_zone = 'UTC' in my environment.rb. I can use Time.now.utc.to_date instead of Date.today but it makes no difference.

• Dynamic Comparison Operators in PHP

  Hi All Is it possible, in any way, to pass comparison operators as variables to a function? I am looking at producing some convenience functions, for example (and I know this won't work): function isAnd($var, $value, $operator = '==') { if(isset($var) && $var $operator $value) return true; } if(isAnd(1, 1, '===')) echo 'worked'; Thanks in advance.

• SQL/Schema comparison and upgrade

  - by Workshop Alex

  I have a simple situation. A large organisation is using several different versions of some (desktop) application and each version has it's own database structure. There are about 200 offices and each office will have it's own version, which can be one of 7 different ones. The company wants to upgrade all applications to the latest versions, which will be version 8. The problem is that they don't have a separate database for each version. Nor do they have a separate database for each office. They have one single database which is handled by a dedicated server, thus keeping things like management and backups easier. Every office has it's own database schema and within the schema there's the whole database structure for their specific application version. As a result, I'm dealing with 200 different schema's which need to be upgraded, each with 7 possible versions. Fortunately, every schema knows the proper version so checking the version isn't difficult. But my problem is that I need to create upgrade scripts which can upgrade from version 1 to version 2 to version 3 to etc... Basically, all schema's need to be bumped up one version until they're all version 8. Writing the code that will do this is no problem. the challenge is how to create the upgrade script from one version to the other? Preferably with some automated tool. I've examined RedGate's SQL Compare and Altova's DatabaseSpy but they're not practical. Altova is way too slow. RedGate requires too much processing afterwards, since the generated SQL Script still has a few errors and it refers to the schema name. Furthermore, the code needs to become part of a stored procedure and the code generated by RedGate doesn't really fit inside a single procedure. (Plus, it's doing too much transaction-handling, while I need everything within a single transaction. I have been considering using another SQL Comparison tool but it seems to me that my case is just too different from what standard tools can deliver. So I'm going to write my own comparison tool. To do this, I'll be using ADOX with Delphi to read the catalogues for every schema version in the database, then use this to write the SQL Statements that will need to upgrade these schema's to their next version. (Comparing 1 with 2, 2 with 3, 3 with 4, etc.) I'm not unfamiliar with generating SQL-Script-Generators so I don't expect too many problems. And I'll only be upgrading the table structures, not any of the other database objects. So, does anyone have some good tips and tricks to apply when doing this kind of comparisons? Things to be aware of? Practical tips to increase speed?

• Creating date based back entries for a blog and its site registration

  - by open_sourse

  So I am showing a blog to a colleague and telling him how the author has been regularly blogging for over ten years now. My colleague tells me that anyone can register a domain name and start entries from say circa 2000. When I argued that the site registration date can easily show that the registration was done recently he put forward two arguments: The author can claim that he moved from an old domain name which was registered many years ago and lapsed. So he took the data and rebuilt it in the new site. The author can buy an expired domain which was on the internet for many years. I am not sure if these ways can work to con someone to believing you have been a blogger for over a decade. But I do not have enough expertise in the topic to refute him. So I thought I would ask the wise community here at StackExchange. Can anyone give me some insight?

• How to make Date locale-independent?

  - by folone

  I have a db, that stores dates in OleDateTime format, in GMT timezone. I've implemented a class, extending Date in java to represent that in classic date format. But my class is locale-dependent (I'm in GMT+2). Therefore, it converts the date in the db as date - 2 hours. How do I make it convert the date correctly? I want my class to be locale-independent, always using GMT timezone. Actually, the question is: class MyOleDateTime extends Date { static { Locale.setDefault(WhatGoesHere?) } // ... some constructors // ... some methods }
