  • How to move a Mercurial repository created on a local PC to a web server?

    - by Tim Murphy
    I have created and committed to Mercurial repository that was created on my local drive. I now have a remote Windows 2003 web server setup to serve repositories via hgwebdir.cgi. How do I move the locally created repository to the web server? It looks like an ftp of the .hg folder on the local drive to the remote web server does the trick. Am I doing it the right way. Is there a more efficient way?

  • Should i use TabContainer for multiple pages?

    - by Tim
    I'm considering if it is a good idea to use an ASP.Net TabContainer-Control in the way that every TabPanel contains content of a different page. For example: Next i want to implement in my application is the masterdata management. Normally i would create one aspx page for every masterdata-table (f.e. Customer - MD_Customer.aspx). Then i would add a link into my Menu to this page. Now i'm thinking of creating one aspx page for all(Masterdata.aspx) with a Tabcontainer and an UpdatePanel for every type of Masterdata. The link it the menu could have an additional MDType as URL-Parameter. My main concerns are related to performance(one "page" for every TabPanel currently means 7 "pages" in one) and maintainability because of increasing complexity. Is it a good approach or a bad idea? Thanks

  • How does Scrum work when you have multiple projects?

    - by Tim K.
    I'm fairly well read in the benefits and processes of Scrum. I get the ideas on the backlog, burndown charts, iterations, using user stories, and other various concepts of the Scrum "framework". With that said... I work for a web development firm that manages multiple projects at one time, with six team members that make up the "production team". How does Scrum work with having multiple projects? Do you still just schedule an iteration for a single project in a certain amount of time and the entire team works on it, and then you move on to the next project with a new iteration when that iteration is completed? Or is there an "agile" way in managing multiple projects with their own iterations with only one team at the same time?

  • hunting maven dependencies

    - by Tom
    I want to start using maven in code I distribute but I can't find an efficient way to work with dependencies. Every new dependency takes me far too long to add. As a simple example, I need to add Tomcat for compilation. Do I really have to manually trawl the repo in my browser to find the group-id, artifact-id and version number? In every case it seems easier to find the non-maven downloads. I hope I've missed something obvious.

  • Default tablespace for indexes in postgres

    - by tom
    Just wondering if its possible to set a default tablespace in postgres to keep indexes. Would like the databases to live on the default tablespace for postgres, however, would like to get the indexes on a different set of disks just to keep the i/o traffic separated. It does not appear to me that it can be done without going in and doing an ALTER index TABLESPACE command, and then the index is moved and will stay there, but the databases and indexes are part of a django app, so non-django intervention can cause some problems.

  • Performance optimization for mssql: decrease stored procedures execution time or unload the server?

    - by tim
    Hello everybody! We have a web service which provides search over hotels. There is a problem with performance: a single request to the service takes around 5000 ms. Almost all of the time is spent in database by executing storing procedures. During the request our server (mssql2008) consumes ~90% of the processor time. When 2 requests are made in parallel the average time grows and is around 7000 ms. When number of request is increasing, the average time of response is increasing as well. We have 20-30 requests per minute. Which kind of optimization is the best in this case having in mind that the goal is to provide stable response time for the service: 1) Try to decrease the stored procedures execution time 2) Try to find the way how to unload the server It is interesting to hear from people who deal with booking sites. Thanks!

  • Stackoverflow interesting tags

    - by Tom
    So, that's how works Interesting Tags: I add into them my interested tags like php, mysql, jquery and so on. Then, if any of questions has the same tags as mine it makes background orange. I understand how to use jquery to do that (there were related questions to that), but without mysql it can't be done. Now, here is a question. How is it done? I imagine like that: There is a row in mysql for every member, let's call it "interested_tags". After I write and submit my tag through input, it is being written in a row "interested_tags". Then, the main page has a query which shows all answers and it always checks answer's with mine tags with strpos like this if(strpos($question_tags, $my_tags) === true) {        //and here will be made background orange } Am I thinking right or is there any way to do it?

  • Search tool that uses a grammar rather than regular expression?

    - by Tom Hubbard
    Are there any search tools that allow you to set up a simple token/grammar parsing system that work similar to regular expressions? What we want to do is search our ColdFusion code for queries that do not have cfqueryparams in them. A regular expression gets a bit tough in this situation because I can't keep track of the start tags while looking for something else before getting an end tag. It seems like a parsing system would work more accurately.

  • Program always returns binary '>>' : no operator found which takes a left-hand operand of type error

    - by Tom Ward
    So I've been set a task to create a temperature converter in C++ using this equation: Celsius = (5/9)*(Fahrenheit – 32) and so far I've come up with this (I've cut out the 10 lines worth of comments from the start so the code posted begins on line 11, if that makes any sense) #include <iostream> #include <string> #include <iomanip> #include <cmath> using namespace std; int main () { float celsius; float farenheit; std::cout << "**************************" << endl; std::cout << "*4001COMP-Lab5-Question 1*" << endl; std::cout << "**************************" << endl << endl; std::cout << "Please enter a temperature in farenheit: "; std::cin >> farenheit >> endl; std::cout << "Temperature (farenheit): " << endl; std::cout << "Temperature (celsius): " << celsius << endl; std::cin.get(); return 0; } Everytime I try to run this program I get a heap of errors with this one appearing every time: 1m:\visual studio 2010\projects\week 5\week 5\main.cpp(26): error C2678: binary '' : no operator found which takes a left-hand operand of type 'std::basic_istream<_Elem,_Traits' (or there is no acceptable conversion) I've tried everything I can think of to get rid of this error but it reappears every time, any idea on how to fix this?

  • Best practices for "search data class" in ASP.NET MVC

    - by Tim Ridgely
    Hi everybody, I'm hoping this isn't too subjective, but I'm new to ASP.NET MVC and I'm trying to figure out how others may have solved similar problems. Basically, I have two entities, Customers and Orders. A customer has many orders; an order belongs to exactly one customer. I'm making an Order Search feature that should allow a user to search for orders based on order or customer information. Pretty straightforward, I think. I've read in other posts that the search controller should use GET, but I think it makes more sense to use POST because of the large number of search params. I'm using Entity Framework to create my models, and that's in a separate class library project and namespace. This article talks about using binding instead of Request.Form to get at the POST data. Would it make decent sense to make a class to hold all the search data that could be materialized by the magic model binding? Otherwise I'd just be poking through the FormCollection to pull out particular values, which might be fine. Where would you recommend making such a class?

  • Is it possible to have a variadic function in C with no non-variadic parameter?

    - by Tim
    I have the following function: void doStuff(int unusedParameter, ...) { va_list params; va_start(params, unusedParameter); /* ... */ va_end(params); } As part of a refactor, I'd like to remove the unused parameter without otherwise changing the implementation of the function. As far as I can tell, it's impossible to use va_start when you don't have a last non-variadic parameter to refer to. Is there any way around this? Background: It is in fact a C++ program, so I could use some operator-overloading magic as suggested here, but I was hoping not to have to change the interface at this point. The existing function does its work by requiring that the variable argument list be null-terminated, and scanning for the NULL, therefore it doesn't need a leading argument to tell it how many arguments it has.

  • Django Admin Running Same Query Thousands of Times for Model

    - by Tom
    Running into an odd . . . loop when trying to view a model in the Django admin. I have three related models (code trimmed for brevity, hopefully I didn't trim something I shouldn't have): class Association(models.Model): somecompany_entity_id = models.CharField(max_length=10, db_index=True) name = models.CharField(max_length=200) def __unicode__(self): return self.name class ResidentialUnit(models.Model): building = models.CharField(max_length=10) app_number = models.CharField(max_length=10) unit_number = models.CharField(max_length=10) unit_description = models.CharField(max_length=100, blank=True) association = models.ForeignKey(Association) created = models.DateTimeField(auto_now_add=True) updated = models.DateTimeField(auto_now=True) def __unicode__(self): return '%s: %s, Unit %s' % (self.association, self.building, self.unit_number) class Resident(models.Model): unit = models.ForeignKey(ResidentialUnit) type = models.CharField(max_length=20, blank=True, default='') lookup_key = models.CharField(max_length=200) jenark_id = models.CharField(max_length=20, blank=True) user = models.ForeignKey(User) is_association_admin = models.BooleanField(default=False, db_index=True) show_in_contact_list = models.BooleanField(default=False, db_index=True) created = models.DateTimeField(auto_now_add=True) updated = models.DateTimeField(auto_now=True) _phones = {} home_phone = None work_phone = None cell_phone = None app_number = None account_cache_key = None def __unicode__(self): return '%s' % self.user.get_full_name() It's the last model that's causing the problem. Trying to look at a Resident in the admin takes 10-20 seconds. If I take 'self.association' out of the __unicode__ method for ResidentialUnit, a resident page renders pretty quickly. Looking at it in the debug toolbar, without the association name in ResidentialUnit (which is a foreign key on Resident), the page runs 14 queries. With the association name put back in, it runs a far more impressive 4,872 queries. The strangest part is the extra queries all seem to be looking up the association name. They all come from the same line, the __unicode__ method for ResidentialUnit. Each one is the exact same thing, e.g., SELECT `residents_association`.`id`, `residents_association`.`jenark_entity_id`, `residents_association`.`name` FROM `residents_association` WHERE `residents_association`.`id` = 1096 ORDER BY `residents_association`.`name` ASC I assume I've managed to create a circular reference, but if it were truly circular, it would just die, not run 4000x and then return. Having trouble finding a good Google or StackOverflow result for this.

  • Want to check fields for data fast.

    - by Tom
    We have a database setup that consists of two parts: a static structure, and dynamic additions. For each database, the dynamic can be different, and sometimes we don't have data for all the dynamic fields. Rigt now, we check for empties by looking at the total count of records in the entire table, but we want to move to a more refined method of checking for empties if possible. Is it possible to quickly check through several hundred fields and see which ones are empty and which ones are populated?

  • multi-valued property query in GAE

    - by Tim
    class Person{ @Persistent private List tags = ArrayList() } I want to let the user query a person based on his/her tag, so I had my query filter like this: tags.contains(tagValue1) and if the user want to search for multiple tags, I would just add to the filter so if the user is searching for 3 tags, then the query would be tags.contains(tagValue1) && tags.contains(tagValue2) && tags.contains(tagValue3) I think this approach is wrong, because the datastore then needs to have an index that have the tags property three times... and if the user search for more than 3 tags at a time then it will be broken. What's the proper way to do this? Do you guys have any suggestions?

  • How do you detach an array of strings from shared memory? C

    - by Tim
    I have: int array_id; char* records[10]; // get the shared segment if ((array_id = shmget(IPC_PRIVATE, 1, 0666)) == -1) { perror("Array Creating"); } // attach records[0] = (char*) shmat(array_id, (void*)0, 0); if ((int) *records == -1) { perror("Array Attachment"); } which works fine, but when i try and detach i get an "invalid argument" error. // detach int error; if( (error = shmdt((void*) records[0])) == -1) { perror(array detachment); } any ideas? thank you

  • What naming conventions exist for the primary Node.js file?

    - by Tom Dworzanski
    This question has been completely edited in hopes that it will be reopened. The naming of the main Node.js file is something left to the user and and does not seem to be defined by any well established convention. In hopes of finding a good name, I am curious if there are naming conventions in other parts of the Node.js ecosystem that might suggest a name to use. Some names I have seen are: app.js, index.js, main.js, server.js, etc. Please provide only well documented standards in answers.

  • JavaScript sorting array from nested array?

So I want the most popular letter to be first. How would I do this?
