  • How do I tell sudo to write files with a umask of 0022?

    - by mipadi
    I recently upgrading to Snow Leopard. I have noticed that some files written by MacPorts are installed with the wrong permission -- they are written with a umask of 0077. I think I have narrowed down the problem: The port command is invoked via sudo. My .bashrc file specifies a umask of 0077. On older versions of OS X (10.5 and below), sudo used the umask of the root user (which was 0022); however, now it uses my umask of 0077. Is there anyway to have sudo use the old behavior? Right now, it's kind of annoying because I have to use sudo to run simple commands like port installed, port outdated, etc. (The problem is described in more detail in this MacPorts ticket.) Edit I discovered the umask option for sudo, and in /etc/sudoers I added the following line: Defaults umask=0022 However, this did not function as desired, because the real umask used by sudo is the union of the user mask with this default mask.

  • Why won't Outlook sync with Google Calendar?

    - by mipadi
    A colleague of mine is having problems with Outlook and Google Calendar Sync. He got a new machine and set up Outlook 2007 on that machine. He also installed Google Calendar Sync. However, when he synced Outlook with Google Calendar, he got a number of duplicate entries in Outlook's calendar. We tried deleting all entries in the Outlook calendar and doing a 1-way sync from Google Calendar to Outlook, but the duplicated entries appeared again. We ultimately removed the duplicated entries manually, but we experienced problems pushing the changes back to Google Calendar, so we deleted the calendar in Google Calendar and tried to sync again (using a 1-way sync from Outlook to Google). Now Google Calendar Sync says that it is synchronizing, but no entries appear in the Google Calendar calendar. What could the problem be?

  • How can I avoid an error in this .htaccess file?

    - by mipadi
    I have a blog. The blog is stored under the /blog/ prefix on my website. It has the usual URLs for a blog, so articles have URLs in the format /blog/:year/:month/:day/:title/. First and foremost, I want to automatically redirect visitors to the www subdomain (in case they leave that off), and internally rewrite the root URL to /blog/, so that the front page of the blog appears on the front page of the site. I have accomplished that with the following set of rewrite rules in my .htaccess file: RewriteEngine On # Rewrite monkey-robot.com to www.monkey-robot.com RewriteCond %{HTTP_HOST} ^monkey-robot\.com$ RewriteRule ^(.*)$ http://www.monkey-robot.com/$1 [R=301,L] RewriteRule ^$ /blog/ [L] RewriteRule ^feeds/blog/?$ /feeds/blog/atom.xml [L] That works fine. The problem is that the front page of the blog now appears at two distinct URLs: / and /blog/. So I'd like to redirect the /blog/ URL to the root URL. Initially I tried to accomplish this with the following set of rewrite rules: RewriteEngine On # Rewrite monkey-robot.com to www.monkey-robot.com RewriteCond %{HTTP_HOST} ^monkey-robot\.com$ RewriteRule ^(.*)$ http://www.monkey-robot.com/$1 [R=301,L] RewriteRule ^$ /blog/ [L] RewriteRule ^blog/?$ / [R,L] RewriteRule ^feeds/blog/?$ /feeds/blog/atom.xml [L] But that gave me an infinite redirect (maybe because of the preceding rule?). So then I tried this set: RewriteEngine On # Rewrite monkey-robot.com to www.monkey-robot.com RewriteCond %{HTTP_HOST} ^monkey-robot\.com$ RewriteRule ^(.*)$ http://www.monkey-robot.com/$1 [R=301,L] RewriteRule ^$ /blog/ [L] RewriteRule ^blog/?$ http://www.monkey-robot.com/ [R,L] RewriteRule ^feeds/blog/?$ /feeds/blog/atom.xml [L] But I got a 500 Internal Server Error with the following log message: Invalid command '[R,L]', perhaps misspelled or defined by a module not included in the server configuration What gives? I don't think [R,L] is a syntax error.

  • Why do funky characters show up in these Microsoft Word equations?

    - by mipadi
    A colleague sent me a document created with Microsoft Office 2007 that contains equations. On her end, the document looks fine; however, on my end, the equations show up with these funky characters overlaid on them: Why do these weird characters show up, and how do I fix it? The equations appear like this in both .doc and .docx documents. Additionally, when I double-click on the equations to edit them, I get a warning that the equations were created with a newer version of the equation editor, and when I close the editing window, the equations are gone completely. I think this might indicate a compatibility problem, but I am not sure of a solution.

  • Is it ever a bad idea to publish a sitemap for a blog?

    - by mipadi
    I have a blog, and I have been considering publishing a sitemap for it, which would include the index page, archives page, and an entry for each individual blog post. Is this ever a bad idea? Is it a good (or useful) idea? I'm particularly interested in the <changefreq> element: I edit posts from time to time, and while that's not a common occurrence, I don't want to set a particularly infrequent change frequency that prevents search engines like Google from indexing the edits. (The sitemaps protocol says that search engines may still crawl the pages more frequently, but has no further details on the matter.)

  • How can I filter these Django records?

    - by mipadi
    I have a set of Django models as shown in the following diagram (the names of the reverse relationships are shown in the yellow bubbles): In each relationship, a Person may have 0 or more of the items. Additionally, the slug field is (unfortunately) not unique; multiple Person records may have the same slug fields. Essentially these records are duplicates. I want to obtain a list of all records that meet the following criteria: All duplicate records (that is, having the same slug) with at least one Entry OR at least one Audio OR at least one Episode OR at least one Article. So far, I have the following query: Person.objects.values('slug').annotate(num_records=Count('slug')).filter(num_records__gt=1) This groups all records by slug, then adds a num_records attribute that says how many records have that slug, but the additional filtering is not performed (and I don't even know if this would work right anyway, since, given a set of duplicate records, one may have, e.g., and Entry and the other may have an Article). In a nutshell, I want to find all duplicate records and collapse them, along with their associated models, into one record. What's the best way to do this with Django?

  • My Rails app is returning HTTP 500 for all its URLs, but nothing shows up in the log file. How can I

    - by mipadi
    I have a Rails app that is running on a production server with Apache and Phusion Passenger. The app works fine locally when using Mongrel, but whenever I try to load a URL on the production server, it returns HTTP 500. I know the server is working properly, because I can get the static elements of the application (e.g., JavaScript files, stylesheets, images) just fine. I've also checked the Passenger status and it is loading the app (it must be, since the app's 500 Internal Server Error page is returned, not just the default Apache one). Also, when I load the app via script/console production and do something like app.get("/"), 500 is also returned. The problem is that there is nothing in the log files to indicate the problem. production.log is empty. The Apache error logs show no problems with Apache, either. I'm stumped as to what's going on and I'm not sure how to diagnose the problem. I know I may have been a bit vague, but can anyone give a suggestion on what the problem may be? Or at least a way I can go about diagnosing it?

  • How can I fix this clang warning: "Object with +0 retain counts returned to caller where +1 (owning)

    - by mipadi
    I have a piece of Objective-C code that looks like the following: - (NSString *)copyData:(NSData *)data { NSString *path = [[[self outputDirectory] stringByAppendingPathComponent:@"archive"] stringByAppendingPathExtension:@"zip"]; NSLog(@"Copying data to %@", path); [data writeToFile:path atomically:NO]; return path; } The code is called from an initializer that looks like this: - (id)initWithData:(NSData *)data { if ((self = [super init]) != nil) { NSString *path = [self copyData:data]; // Line 41 (referenced in warning, shown below) return [self initWithContentsOfFile:path]; } return self; } When running the clang static analyzer, I get the following warnings for the path variable: Potential leak of an object allocated on line 41 and stored into 'path' Object with +0 retain counts returned to caller where +1 (owning) retain count is expected I'm confused. My understanding is that stringByAppendingPathComponent should not return an autoreleased string, so it should have a net retain count of 0. (Obviously I don't want to retain it.) I've tried altering copyData: to return the following, but it didn't get rid of the warning: return [[path retain] autorelease]; So what's the deal with this warning?

  • How do I dismiss an NSPanel when creating or opening a new document?

    - by mipadi
    I am working on a document-based Cocoa application. At startup, the user is presented with a "welcome panel" (of type NSPanel) with buttons for common actions like "Create New Document" and "Open Existing Document". These actions are linked to the first responder's newDocument: and openDocument: actions, respectively, just like the matching items in the File menu. Everything works as expected...with two caveats: The welcome panel is not dismissed when creating or opening a new document. Document windows do not have focus when they are created. I have partially solved #1 by making my application controller a delegate of the welcome panel. When clicking the "Open Existing Document" button, the panel resigns its key status (since a file browser dialog is being opened), so I can close the panel in the delegate's windowDidResignKey: method. However, I can't figure out how to close the panel when creating a new document, since I can't find a notification that is posted, or a delegate method that is called, when creating a new document. And ultimately, #2 is still a problem, since the document windows don't gain focus when they're created. I have only subclassed NSDocument -- I'm not using a custom document or window controller at all. I've also tried changing the panel to an NSWindow, thinking that an NSWindow may behave differently, but the same problems are occurring.

  • How do I configure the Python logging module in Django?

    - by mipadi
    I'm trying to configure logging for a Django app using the Python logging module. I have placed the following bit of configuration code in my Django project's settings.py file: import logging import logging.handlers import os date_fmt = '%m/%d/%Y %H:%M:%S' log_formatter = logging.Formatter(u'[%(asctime)s] %(levelname)-7s: %(message)s (%(filename)s:%(lineno)d)', datefmt=date_fmt) log_dir = os.path.join(PROJECT_DIR, "var", "log", "my_app") log_name = os.path.join(log_dir, "nyrb.log") bytes = 1024 * 1024 # 1 MB if not os.path.exists(log_dir): os.makedirs(log_dir) handler = logging.handlers.RotatingFileHandler(log_name, maxBytes=bytes, backupCount=7) handler.setFormatter(log_formatter) handler.setLevel(logging.DEBUG) logging.getLogger().setLevel(logging.DEBUG) logging.getLogger().addHandler(handler) logging.getLogger(__name__).info("Initialized logging subsystem") At startup, I get a couple Django-related messages, as well as the "Initialized logging subsystem", in the log files, but then all the log messages end up going to the web server logs (/var/log/apache2/error.log, since I'm using Apache), and use the standard log format (not the formatter I designated). Am I configuring logging incorrectly?

  • Why does this Rails named scope return empty (uninitialized?) objects?

    - by mipadi
    In a Rails app, I have a model, Machine, that contains the following named scope: named_scope :needs_updates, lambda { { :select => self.column_names.collect{|c| "\"machines\".\"#{c}\""}.join(','), :group => self.column_names.collect{|c| "\"machines\".\"#{c}\""}.join(','), :joins => 'LEFT JOIN "machine_updates" ON "machine_updates"."machine_id" = "machines"."id"', :having => ['"machines"."manual_updates" = ? AND "machines"."in_use" = ? AND (MAX("machine_updates"."date") IS NULL OR MAX("machine_updates"."date") < ?)', true, true, UPDATE_THRESHOLD.days.ago] } } This named scope works fine in development mode. In production mode, however, it returns the 2 models as expected, but the models are empty or uninitialized; that is, actual objects are returned (not nil), but all the fields are nil. For example, when inspecting the return value of the named scope in the console, the following is returned: [#<Machine >, #<Machine >] But, as you can see, all the fields of the objects returned are set to nil. The production and development environments are essentially the same. Both are using a SQLite database. Any ideas what's going wrong?

  • How can I use SQL to select duplicate records, along with counts of related items?

    - by mipadi
    I know the title of this question is a bit confusing, so bear with me. :) I have a (MySQL) database with a Person record. A Person also has a slug field. Unfortunately, slug fields are not unique. There are a number of duplicate records, i.e., the records have different IDs but the same first name, last name, and slug. A Person may also have 0 or more associated articles, blog entries, and podcast episodes. If that's confusing, here's a diagram of the structure: I would like to produce a list of records that match this criteria: duplicate records (i.e., same slug field) for people who also have at least 1 article, blog entry, or podcast episode. I have a SQL query that will list all records with the same slug fields: SELECT id, first_name, last_name, slug, COUNT(slug) AS person_records FROM people_person GROUP BY slug HAVING (COUNT(slug) > 1) ORDER BY last_name, first_name, id; But this includes records for people that may not have at least 1 article, blog entry, or podcast. Can I tweak this to fit the second criteria?

  • Where is the best place to put <script> tags in HTML markup?

    - by mipadi
    When embedding JavaScript in an HTML document, where is the best place to put the <script> tags and included JavaScript? I seem to recall that you are not supposed to place these in the <head> section, but placing at the beginning of the <body> section is bad, too, since the JavaScript will have to be parsed before the page is rendered completely (or something like that). This seems to leave the end of the <body> section as a logical place for <script> tags. So, where is the best place to put the <script> tags? (This question references this question, in which it was suggested that JavaScript function calls should be moved from <a> tags to <script> tags. I'm specifically using JQuery, but more general answers are also appropriate.)

  • How do I make an About window the front-most window in a Cocoa application with no UI?

    - by mipadi
    I'm building a Cocoa application that runs as an item in the status bar. This application has an About window and an item to activate that about window, using the standard Cocoa mechanism for doing so (-[NSApplication orderFrontStandardAboutPanel:]). Naturally this is all hooked up automagically. It works great except for one thing: unlike most About windows, it shows up underneath all other windows, rather than on top. I believe this is because the application does not have a UI, so all its windows are automatically beneath other windows. Is there a way I can hook into the NSApplication mechanism for displaying the About window so I can send it to the front? I've poked around in the docs for NSApplication, but there's no way to get a reference to the About window that I can see so that I can make it appear on top.

  • Problem with setContentBorderThickness:forEdge: not actually setting the value

    - by jxpx777
    I'm trying to use setContentBorderThickness:forEdge: to create a bottom bar in a Cocoa application. mipadi was on to something, but in testing it out, I think maybe this is a slightly different problem: -(void) adjustContentBorderBasedOnArrayControllerSelection{ if(([[self.resultsArrayController selectionIndexes] count] == 0)){ [[self window] setContentBorderThickness:40.0f forEdge:CGRectMinYEdge]; NSLog(@"%f", [[self window] contentBorderThicknessForEdge:CGRectMinYEdge]); } else { [[self window] setContentBorderThickness:60.0f forEdge:CGRectMinYEdge]; NSLog(@"%f", [[self window] contentBorderThicknessForEdge:CGRectMinYEdge]); } } Both of those NSLog() messages show the thickness value is 0.0 even after I explicitly set it. Anyone know what's up with that?

  • Is Python Interpreted or Compiled?

    - by crodjer
    This is just a wondering I had while reading about interpreted and compiled languages. Ruby is no doubt an interpreted language, since source code is compiled by an interpreter at the point of execution. On the contrary C is a compiled language, as one have to compile the source code first according to the machine and then execute. This results is much faster execution. Now coming to Python: A python code (somefile.py) when imported creates a file (somefile.pyc) in the same directory. Let us say the import is done in a python shell or django module. After the import I change the code a bit and execute the imported functions again to find that it is still running the old code. This suggests that *.pyc files are compiled python files similar to executable created after compilation of a C file, though I can't execute *.pyc file directly. When the python file (somefile.py) is executed directly ( ./somefile.py or python somefile.py ) no .pyc file is created and the code is executed as is indicating interpreted behavior. These suggest that a python code is compiled every time it is imported in a new process to crate a .pyc while it is interpreted when directly executed. So which type of language should I consider it as? Interpreted or Compiled? And how does its efficiency compare to interpreted and compiled languages? According to wiki's Interpreted Languages page it is listed as a language compiled to Virtual Machine Code, what is meant by that? Update Looking at the answers it seems that there cannot be a perfect answer to my questions. Languages are not only interpreted or only compiled, but there is a spectrum of possibilities between interpreting and compiling. From the answers by aufather, mipadi, Lenny222, ykombinator, comments and wiki I found out that in python's major implementations it is compiled to bytecode, which is a highly compressed and optimized representation and is machine code for a virtual machine, which is implemented not in hardware, but in the bytecode interpreter. Also the the languages are not interpreted or compiled, but rather language implementations either interpret or compile code. I also found out about Just in time compilation As far as execution speed is concerned the various benchmarks cannot be perfect and depend on context and the task which is being performed. Please tell if I am wrong in my interpretations.
