  • Release objects before returning a value based on those object?

    - by Moshe
    Consider the following method, where I build a string and return it. I would like to release the building blocks of the sting, but then the string is based on values that no longer exists. Now what? Am I leaking memory and if so, how can I correct it? - (NSString) getMiddahInEnglish:(int)day{ NSArray *middah = [[NSArray alloc] initWithObjects:@"Chesed", @"Gevurah", @"Tiferes", @"Netzach", @"Hod", @"Yesod", @"Malchus"]; NSString *firstPartOfMiddah = [NSString stringWithFormat: @"%@", [middah objectAtIndex: ((int)day% 7)-1]]; NSString *secondPartOfMiddah = [NSString stringWithFormat: @"%@", [middah objectAtIndex: ((int)day / 7)]]; NSString *middahStr = [NSString string@"%@ She'bi@%", firstPartOfMiddah, secondPartOfMiddah]; [middah release]; [firstPartOfMiddah release]; [secondPartOfMiddah release]; return middahStr; }

  • Grouping search results with thinking_sphinx plugin for rails

    - by Shagymoe
    I can use the following to group results, but it only returns one result per group. @results = Model.search params[:search_query], :group_by => 'created_at', :group_function => :day, :page => params[:page], :per_page => 50 So, if I display the results by day, I only get one result per day. <% @results.each_with_groupby do |result, group| %> <div class="group"><%= group %></div> <ul class="result"> <li><%= result.name %></li> </ul> <% end %> Do I have to parse the @results array and group them by date manually or am I missing something? Here is the line from the sphinx docs: http://sphinxsearch.com/docs/current.html#clustering "The final search result set then contains one best match per group."

  • Javascript : assign variable in if condition statement, good practice or not?

    - by Michael Mao
    Hi all: I moved one years ago from classic OO languages such like Java to Javascript. The following code is definitely not recommended (or even not correct) in Java: if(dayNumber = getClickedDayNumber(dayInfo)) { alert("day number found"); } function getClickedDayNumber(dayInfo) { dayNumber = dayInfo.indexOf("fc-day"); if(dayNumber != -1) //substring found { //normally any calendar month consists of "40" days, so this will definitely pick up its day number. return parseInt(dayInfo.substring(dayNumber+6, dayNumber+8)); } else return false; } Basically I just found out that I can assign a variable to a value in an if condition statement, and immediately check the assigned value as if it is boolean. For a safer bet, I usually separate that into two lines of code, assign first then check the variable, but now that I found this, I am just wondering whether is it good practice or not in the eyes of experienced javascript developers? Many thanks in advance.

  • How do I use timezones with a datetime object in python?

    - by jidar
    How do I properly represent a different timezone in my timezone? The below example only works because I know that EDT is one hour ahead of me, so I can uncomment the subtraction of myTimeZone() import datetime, re from datetime import tzinfo class myTimeZone(tzinfo): """docstring for myTimeZone""" def utfoffset(self, dt): return timedelta(hours=1) def myDateHandler(aDateString): """u'Sat, 6 Sep 2008 21:16:33 EDT'""" _my_date_pattern = re.compile(r'\w+\,\s+(\d+)\s+(\w+)\s+(\d+)\s+(\d+)\:(\d+)\:(\d+)') day, month, year, hour, minute, second = _my_date_pattern.search(aDateString).groups() month = [ 'JAN', 'FEB', 'MAR', 'APR', 'MAY', 'JUN', 'JUL', 'AUG', 'SEP', 'OCT', 'NOV', 'DEC' ].index(month.upper()) + 1 dt = datetime.datetime( int(year), int(month), int(day), int(hour), int(minute), int(second) ) # dt = dt - datetime.timedelta(hours=1) # dt = dt - dt.tzinfo.utfoffset(myTimeZone()) return (dt.year, dt.month, dt.day, dt.hour, dt.minute, dt.second, 0, 0, 0) def main(): print myDateHandler("Sat, 6 Sep 2008 21:16:33 EDT") if __name__ == '__main__': main()

  • Calculation with dates and different locales in Crystal Reports for Eclipse?

    - by Bevor
    Hello, I'm using Crystal Reports for Eclipse 2.0.4 and I have a problem. I use a formula in an report to subtract one day from a string which is a date: ToText(CDate({Agreement.EndDate})-1, "dd.MM.yyyy"); This works for the German locale. With an English locale, the calculation is absolutely wrong because the day and month is interchanged. For example: When {Agreement.EndDate} is 07.05.2010 and I subtract one day from it, I get 06.04.2010 with the German locale but 04.07.2010 with an English locale. How can I solve this that I works for different locales?

  • how to handle it if the management just keep on giving me spec after spec non-stop?

    - by Jian Lin
    As a programmer, I feel burnt out if the management give me spec after spec, day after day. I think I can code 6 hours a day very focused, but non-stop coding does burn me out a little, especially it is 1 year or 18 months non-stop. A mere 1 week or 2 week vacation per year isn't going to help much. Sometimes I want to take some time to learn new things, or just to take a break for a month so as to re-charge, like back in college when we have holidays for 1 month during winter or 2.5 months during summer. What do you think?

  • What good timesheet should and shouldn't have for a small (non programming) 50 people company?

    - by MadBoy
    I'm sure most people here had to fill at least one time sheet in their life that made their life miserable, hell it's even the worst time taker ever especially after you have to fill it in hurry. I will be developing some simple TimeSheet application for a small company of 50 people (non programming related, it's actually 4 companies working together) and would like it to be user friendly and as less disturbing as possible. So what in your opinion makes it a good timesheet (lack of it doesn't count :p), what data it should store? Should be only hours per day with possibility to choose project, company and simple overview what you have worked on like: Day 1, 3:00, 'Company 1', 'Project5', 'Name', Short Overview Day 1, 5:00, 'Company 2', 'Project6', 'Name', Short Overview Or should it gather more data? Would it be realy bad if it were an WinForms application considering that I don't know ASP.NET or any other web based language? I would be deploying it using ClickOnce or so.

  • algorithm advice for finding maximum items within a time period

    - by darren
    Hi everyone. I have a database schema that is similar to the following: | User | Event | Date |--------|---------------|------ | 111 | Walked dog | 2009-10-1 | 222 | Walked dog | 2009-10-2 | 333 | Fed Fish | 2009-10-5 | 222 | Did Laundry | 2009-10-6 | 111 | Fed Fish | 2009-10-7 | 111 | Walked dog | 2009-10-18 | 222 | Walked dog | 2009-10-19 | 111 | Fed Fish | 2009-10-21 I would like to produce a query that returns the maximum number of times a user performs some action within a time period. For example, given a time period of 5 days, what is the maximum number of times user 111 walked the dog? The most obvious solution would be to start at some zero point and move forward each day, summing up 5 day periods along the way, then taking the maximum total out of all the 5 day windows. the approach seems incredibly costly however. I would appreciate any suggestions you may have.

  • Group MySQL Data into Arbitrarily Sized Time Buckets

    - by Eric J.
    How do I count the number of records in a MySQL table based on a timestamp column per unit of time where the unit of time is arbitrary? Specifically, I want to count how many record's timestamps fell into 15 minute buckets during a given interval. I understand how to do this in buckets of 1 second, 1 minute, 1 hour, 1 day etc. using MySQL date functions, e.g. SELECT YEAR(datefield) Y, MONTH(datefield) M, DAY(datefield) D, COUNT(*) Cnt FROM mytable GROUP BY YEAR(datefield), MONTH(datefield), DAY(datefield) but how can I group by 15 minute buckets?

  • js regex replace multiple words

    - by Raghav
    I need to replace ${conferance name} with ABC, ${conference day} with Monday in the following sentence. Could some one help me with the regex. var text = "<td>${conference name}</td><td>${conference day}</td>" var list = ["${conferance name}", "${conference day}" ] for (var j = 1; j < list.length; j++) { //Extracting the col name var colName = list[j].split("${"); colName = colName.split("}")[0]; //Replacing the col name text = text.replace(new RegExp('\\$\\{' + colName + '\\}', 'g'), "ABC"); } The above code repalces fine if i have ${conference_name}, but it fails when i have a space in between. The list is a dynamic array. And the Replace statements are also dynamic. I just simulated them as objects here for fitting them in the Regex Statement. Thanks in Advance.

  • Select a row having a column with max value - On a date range

    - by Abhi
    Excuse me for posting a similar question. Please consider this: date value 18/5/2010, 1 pm 40 18/5/2010, 2 pm 20 18/5/2010, 3 pm 60 18/5/2010, 4 pm 30 18/5/2010, 5 pm 60 18/5/2010, 6 pm 25 19/5/2010, 6 pm 300 19/5/2010, 6 pm 450 19/5/2010, 6 pm 375 20/5/2010, 6 pm 250 20/5/2010, 6 pm 310 The query is to get the date and value for each day such that the value obtained for that day is max. If the max value is repeated on that day, the lowest time stamp is selected. The result should be like: 18/5/2010, 3 pm 60 19/5/2010, 6 pm 450 20/5/2010, 6 pm 310 The query should take in a date range like the one given below and find results for that range in the above fashion: where date = to_date('26/03/2010','DD/MM/YYYY') AND date < to_date('27/03/2010','DD/MM/YYYY')

  • How do you manage your time as a team leader?

    - by Bryan Slatner
    Where I work, my role has been evolving from a pure development role to team leadership. I find that this suits me, and I'm generally enjoying it. One aspect of the job that continually vexes me, though, is time management. My day used to be pure coding. Now, I still have a largely full plate of coding duties, but I'm expected to mentor other developers, work on requirements, make design decisions for other developers, evaluate bug reports from users, assign them to developers, and so on. I find that my day has become on interruption after another and the prolonged periods of sustained concentration needed to get any actual quality coding done are becoming rarer and rarer. Today, I finally grabbed my laptop and escaped to a coffee shop so I could get some actual work done. How do the team leads here manage their day -- or manage their workplace -- so they don't let their administrative tasks overwhelm them?

  • basic json > struct question

    I'm working with twitter's api, trying to get the json data from http://search.twitter.com/trends/current.json which looks like: {"as_of":1268069036,"trends":{"2010-03-08 17:23:56":[{"name":"Happy Women's Day","query":"\"Happy Women's Day\" OR \"Women's Day\""},{"name":"#MusicMonday","query":"#MusicMonday"},{"name":"#MM","query":"#MM"},{"name":"Oscars","query":"Oscars OR #oscars"},{"name":"#nooffense","query":"#nooffense"},{"name":"Hurt Locker","query":"\"Hurt Locker\""},{"name":"Justin Bieber","query":"\"Justin Bieber\""},{"name":"Cmon","query":"Cmon"},{"name":"My World 2","query":"\"My World 2\""},{"name":"Sandra Bullock","query":"\"Sandra Bullock\""}]}} My structs look like: type trend struct { name string query string } type trends struct { id string arr_of_trends []trend } type Trending struct { as_of string trends_obj trends } and then I parse the JSON into a variable of type Trending.

  • Can't create a MySQL query that generates 4 rows for each row in the table it references.

    - by UkraineTrain
    I need to create a MySQL query that generates 4 rows for each row in the table it references. I need some of the information in those rows to repeat and some to be different. In the table each row stands for one day. I need to break the day up in 6 hour increments, hence the four rows for each entry. I need to create one column which for each day will have '12AM', '6AM', '12PM', and '6PM' values and another column will have the corresponding numeric values calculated for those entries. Thanks a lot in advance and I will really appreciate any help on this.

Following http://corelib.rubyonrails.org/classes/Time.html#M000240 If I want to add 1 day, it actually adds 60*60*24 days (86,400 days) r=Record.find(:first) =>Sat, 30 Dec 1899 19:00:00 -0600 r.date + (60*60*24) =>Fri, 20 Jul 2136 19:00:00 -0600 But if I do this it actually adds 1 day: t = Time.now =>Mon Jun 14 10:32:51 -0600 2010 t + (60 * 60 * 24) =>Tue Jun 15 10:33:21 -0600 2010 I guess it has to do with the format...how do I make this work?

  • CDateTimeCtrl - preventing 'focus' change when setting date

    - by WalderFrey
    I'd like to use a CDateTimeCtrl to allow the user to select a non-weekend date. So, if the user increments the day (via a keypress) - and the resulting day is found to fall on a weekend - then the control should skip forward to the following Monday (don't let issues about month changes distract you, it's not relevant). Usually it's not a problem: when I handle the DTN_DATETIMECHANGE notification I can check the new date/time and if it's found to be a weekend then I can call SetTime on the control to update the date. However, if I set the style to DTS_SHOWNONE, this call to SetTime causes the control to shift the input 'focus' (term used loosely) to the 'none' checkbox, e.g. away from the day field. This prevents the user from using keyboard input to continue incrementing the date unless they subsequently use the right arrow key to reset the 'focus', which is just nasty. I would dearly like to prevent this focus shift from occurring. Is it even possible?

  • c# .net framework subtracting time-span from date

    - by smkngspcmn
    I want to subtract a time-span from a date-time object. Date is 1983/5/1 13:0:0 (y/m/d-h:m:s) Time span is 2/4/28-2:51:0 (y/m/d-h:m:s) I can use the native DateTime and TimeSpan objects to do this, after converting years and months of the time-span to days (assuming a 30 day month and a ~364 day year). new DateTime(1981,5,1,13,0,0).Subtract(new TimeSpan(878,13,51,0)); With this i get the result: {12/4/1978 11:09:00 PM} But this is not exactly what i expected. If i do this manually (assuming a 30 day month) i get 1981/0/3-10:9:0 This is pretty close to what i'm after except i shouldn't get 0 for month and year should be 1980. So can someone please show me how i can do this manually and avoid getting a 0 month value? Also why do i get a completely different value when i use native classes?
