• MVC2 JSON action, if I want to be RESTful should I allow GET, POST, or Both?

  - by Yads

  The project I'm currently working has a whole bunch of JSON actions in order to populate cascading dropdowns via ajax calls. Since they're technically Select queries and we're trying to be RESTful, we've been marking these actions with the HttpGet attributes. However by default, JsonResultdoes not allow to return results via a GET. So we've had to explicitly call Json(data, JsonRequestBehavior.AllowGet). What I'm wondering is, is this bad practice? Should we only be allowing Post requests to our Json actions? If it makes a difference, this is an enterprise application, that requires a log in to a particular environment before it can be accessed.

• Would dropping X altogether hurt ?

  - by Xavier Maillard

  Hi, I live in the linux terminal all the time under my slackware GNU/linux system (an EeePC). By default, GNU Emacs won't start if It can't find several Xorg libraries. Assuming I will never use X software at all, would it make sense for me to drop all this Xorg stuff and compile emacs again ? Are you aware of anything that could get me into troubles or making GNU Emacs not working at all ? Are there any advantage for me to keep all these dependencies ? I am asking since as said, my main box is an eeepc with little storage and I am dangerously hitting the limits ;-) Regards

• Python os.path.walk() method

  - by Aaron Moodie

  I'm currently using the walk method in a uni assignment. It's all working fine, but I was hoping that someone could explain something to me. in the example below, what is the a parameter used for on the myvisit method? >>> from os.path import walk >>> def myvisit(a, dir, files): ... print dir,": %d files"%len(files) >>> walk('/etc', myvisit, None) /etc : 193 files /etc/default : 12 files /etc/cron.d : 6 files /etc/rc.d : 6 files /etc/rc.d/rc0.d : 18 files /etc/rc.d/rc1.d : 27 files /etc/rc.d/rc2.d : 42 files /etc/rc.d/rc3.d : 17 files /etc/rc.d/rcS.d : 13 files

• Handling "other" option in dropdown select with free text input field

  - by ted776

  Hi, I'm trying to figure out the best way to handle a dropdown list where one of the options "other" shows a hidden text field (via jQuery), where the user can then enter text. Should both the dropdown and the input field be given the same "name" attribute, then server side code runs a check on the values of each in order to know what one is the active value - e.g if the value of the select box is "other", then check the value of the text input field - if this isn't the default value ("enter text"), then it's ok to use this value and save it to the database. Is this a messy approach to this problem?

• Log On As A Service Permission getting removed

  - by VicF

  We have PC's that are in a domain that run a windows service on startup. They continually are having the Log On As A Service permission removed for the domain account that is running the service. So when the PC restarts the service won't run. We can re-add the permission by hand to the Group Policy on the machine or retype the password on the service (which grants the permission) and it runs fine for a day or so. What could be removing it? Could it be a Default Policy that does not have this domain account being applied to the PCs thus removing the Log On As A Service permission?

• What weird encoding is movistar Venezuela sms on blackberry using?

  - by cjp

  Send an sms using the normal GSM TextMessage API on the BlackBerry, get back garbage. It's not unicode, phone is set to 7-bit send. Byte size is only off by one. Is there some default crypto thing, or some weird encoding they use? This code works most everywhere else in the world; this definitely seems like a movistar problem. The string that comes back is random 7-bit ascii except for a few high order bytes. Needless to say the source input text is totally 7 bit chars, which should work in sms, ISO-8859 and look the same in UTF charsets. Anybody seen this or got sms working in code on movistar VZ blackberries?

• select tag sits one pixel lower in Firefox than it does in Chrome

  #allday { width: 180px; height: 20px; margin-top: 2px !important; margin-right: 0px; padding: 0px; -webkit-appearance: menulist; box-sizing: border-box; -webkit-box-align: center; border: 1px solid; border-image: initial; white-space: pre; -webkit-rtl-ordering: logical; color: black; background-color: white; cursor: default; } I inspected the element in both browsers but I'm not really seeing where the discrepancy is. Has anyone been through this before with the select tag?

• How is the implicit segment register of a near pointer determined?

  - by Daniel Trebbien

  In section 4.3 of Intel 64® and IA-32 Architectures Software Developer's Manual. Volume 1: Basic Architecture, it says: A near pointer is a 32-bit offset ... within a segment. Near pointers are used for all memory references in a flat memory model or for references in a segmented model where the identity of the segment being accessed is implied. This leads me to wondering: how is the implied segment register determined? I know that (%eip) and displaced (%eip) (e.g. -4(%eip)) addresses use %cs by default, and that (%esp) and displaced (%esp) addresses use %ss, but what about (%eax), (%edx), (%edi), (%ebp) etc., and can the implicit segment register depend also on the instruction that the memory address operand appears in?

• MySQL query problem

  - by SaltLake

  I've got MySQL table CREATE TABLE stat ( ID int NOT NULL auto_increment PRIMARY KEY, TIMESTAMP_X timestamp DEFAULT CURRENT_TIMESTAMP, # ... some other fields ... ) which contains statistics about site visitors. For getting visits per hour I use SELECT hour(TIMESTAMP_X) as HOUR , count(*) AS HOUR_STAT FROM cms_webstat GROUP BY HOUR ORDER BY HOUR DESC which gives me | HOUR | HOUR_STAT | | 24 | 15 | | 23 | 12 | | 22 | 9 | | 20 | 3 | | 18 | 2 | | 15 | 1 | | 12 | 3 | | 9 | 1 | | 3 | 5 | | 2 | 7 | | 1 | 9 | | 0 | 12 | And I'd like to get following: | HOUR | HOUR_STAT | | 24 | 15 | | 23 | 12 | | 22 | 9 | | 21 | 0 | | 20 | 3 | | 19 | 0 | | 18 | 2 | | 17 | 0 | | 16 | 0 | | 15 | 1 | | 14 | 0 | | 13 | 0 | | 12 | 3 | | 11 | 0 | | 10 | 0 | | 9 | 1 | | 8 | 0 | | 7 | 0 | | 6 | 0 | | 5 | 0 | | 4 | 0 | | 3 | 5 | | 2 | 7 | | 1 | 9 | | 0 | 12 | How should I modify the query to get such result?

• Optimal way to initialize varying objects

  - by John Smith

  I have to initialize a lot of different types of objects based on an integer parameter. They all have the same overall initialization methods. At the moment I have the following code #def APPLE 1 #def PEAR 2 switch (t) { case APPLE: newobj = [[FApple alloc] init]; break; case PEAR: newobj = [[FPear] alloc] init]; break; default: retobj = nil; } I believe there must be a better way to do this. When I add FOrange I have to go and add another line here. What would be a better way?

• How do I put logic in a View a scope or method in a Model?

  - by Angela

  I have the following in the view: <% unless contact_email.statuses.empty?%> (<%= contact_email.statuses.find(:last).status%>) <% end %> contact_email is an instance of a specific model. Could I do something like this? class ContactEmail < ActiveRecord::Base attr_accessible :contact_id, :email_id, :status, :subject, :body, :date_created, :date_sent def status unless contact_email.statuses.empty? contact_email.statuses.find(:last).status end end end is there a better way to do this? is there a way to use the || operator for a default if empty? Basically, I would like to be able to do the following in the View: <%= contact_email.status = IF there is a value, then display it, if not, show nothing.

• Shell Prompt Line Wrapping Issue

  - by Rob

  I've done something to break my Bash Shell Prompt in OS X (10.5.7) Terminal. This is the PS1 that I had configured: PS1='\[\e[1;32m\]\h\[\e[0m\]:\[\e[1;34m\]\w\[\e[0m\]\$ ' As far as I can tell I have the color commands escaping correctly. However when I scroll up and down in my command history I often get line wrapping issues if the historic commands wrap onto multiple lines. I simplified my prompts to the following: PS1='\[\e[1m\]\h:\w\$ \[\e[0m\]' PS2='> ' And I still see something like: localhost:~/Library/Application Support/Firefox/Profiles/knpmxpup.Defau lt/extensions/{1A2D0EC4-75F5-4c91-89C4-3656F6E44B68}$ expocd \{1A2D0EC4-7 5F5-4c91-89C4-3656F6E export PS1="\[ \e[1;32m\]\h\[\e[0m\]: cd Library/Appl ication\ Support/ I've also tried \033 instead of \e. I just included PS2 up there for information, I haven't changed that from the install default. If I completely remove the color codes then everything works fine, any ideas?

• In what package should a "Settings" class be placed?

  - by Tom

  I'm in the middle of building an application but found myself too easily creating new packages without keeping the project's structure in mind. Now, I'm trying to redo the whole project structure on paper first. I am using a Settings class with public properties, accessed as settings for several other classes around the project. Now, since this Settings class applies for the whole project, I am unsure if it should be packaged and if so, in what kind of package should it exist? Or should it be in the root (the default package) with the main application class? I've been thinking about putting it in my utils package, then again I don't think it really is an utlity. Any strategies on how to decide on such package structure for example for a Settings class?

• Is it more secure to run a desktop app in a applet?

  - by Tom Brito

  Fist of all, when I say "run a desktop app in a applet" I mean do a Applet application that runs off-line, instead of a Desktop application that runs inside a JFrame. The little I know about applets (and maybe something I say is wrong, please correct me) is that applets have all permitions not granted by default. Also, the applets run inside a Sandbox, that does not allow information in or out without explicity permition. So, if I am focused on security in my application, its best to run it inside an applet (off-line, for a desktop application) then inside a JFrame. Is it right?

• Aptana Open Resource Key Binding

  - by yagudaev

  The default keyboard shortcut for open resource in Eclipse is Ctrl+Shift+R. It is also the case in Aptana, but there also seems to be a conflicting key since when clicked it brings up a context menu with 2 options "Run" and "Open Resource". How to I avoid having this context menu pop up? I tried to go to the preferences and look for conflicting key-bindings but I could not find it. I am also not sure what "Run" command is actually bound (I tried searching based on the key combination, that did not seem to have worked).

• Drupal, Themekey module doesn't work for a user

  - by Patrick

  hi, Themekey module, (that I use to switch the theme on specific pages of my backend), works for my first Drupal user but it doesn't work for the second Drupal user. In other words, the second user see a page in its default theme. I was wondering if I have to create again the account for this user, and why ThemeKey module doesn't apply consistently to all users. The page I'm customizing a view from which you can edit the content of the website. i've checked for permissions, but I couldn't find any difference between the 2 users. Thanks

• rbenv not changing ruby version

  - by user1443338

  So i installed rbenv according to the github directions. I am running OSX but i have tried this on a Ubuntu 12.04 VM and got the same results. The following is what i get in my terminal when i try to change ruby versions: rbenv versions * 1.9.3-p0 (set by /Users/user/.rbenv/version) 1.9.3-p125 rbenv global 1.9.3-p0 rbenv rehash ruby -v ruby 1.8.7 (2011-12-28 patchlevel 357) [universal-darwin11.0] which ruby /usr/bin/ruby Anyone have any ideas as to why rbenv isnt actually switching the ruby version like it thinks it is? Aslo there is no .rbenv file in the local directory that would be causing the ruby version to default to 1.8.7 rbenv local rbenv: no local version configured for this directory

• How to convert searchTwitter results (from library(twitteR)) into a data.frame?

  - by analyticsPierce

  I am working on saving twitter search results into a database (SQL Server) and am getting an error when I pull the search results from twitteR. If I execute: library(twitteR) puppy <- as.data.frame(searchTwitter("puppy", session=getCurlHandle(),num=100)) I get an error of: Error in as.data.frame.default(x[[i]], optional = TRUE) : cannot coerce class structure("status", package = "twitteR") into a data.frame This is important because in order to use RODBC to add this to a table using sqlSave it needs to be a data.frame. At least that's the error message I got: Error in sqlSave(localSQLServer, puppy, tablename = "puppy_staging", : should be a data frame So does anyone have any suggestions on how to coerce the list to a data.frame or how I can load the list through RODBC?

• [JQuery] Edit Css with animation effect

  - by Pennywise83

  Hi, I've a div in a absolute position with a default "top" value set to "-200px". When i click on the div the "top" value is updated to "0". In this way I see the entire Div. This is the js: $(document).ready(function(){ $("#search_bar").click(function () { $(this).css("top","0"); }); }); Is there a way to achieve this result but with an animation? For example, a slide down effect? Also, when i click another time to the div I'd like that the "top" value will be restored to "-200px".

• How to make UPDATE queries in LINQ to SQL?

  - by Alex

  I like using LINQ to SQL. The only problem is that I don't like the default way of updating tables. Let's say I have the following table with the following columns: ID (primary key), value1, value2, value3, value4, value5 When I need to update something I call UPDATE ... WHERE ID=@id LINQ to SQL call UPDATE ... WHERE ID=@id and value1=@value1 and value2=@value2 and value3=@value3 and value4=@value4 and value5=@value5 I can override this behavior by adding UpdateCheck=UpdateCheck.Never to every column, but with every update of the DataContext class with the GUI, this will be erased. Is there any way to tell LINQ to use this way of updating data?

• How to override <base> tag without removing the tag itself?

  - by sSmacKk

  I'm trying to add some internal links(in the format of a content table, to be able to facilitate webpage navigation) to this site in which a tag is used. Now obviously due to the base tag, every other relative tag will be relative to the base tag href. But in order for me to create this internal content table with the links pointing to different parts of the specific page, i need to get the default URL (before base tag is in effect) so the internal links can work properly. Is there a way to do get around the base tag and accomplish this? PS: if the question is unclear please don't hesitate to ask so i can reformulate Thanks in advance, :D :D

• Hyperlinks in VS2008 Test Result Details

  - by Red XIII

  In case when resulting string in "Test Result Details" (TRD) is very long, the Visual Studio 2008 crashes. I fixed this by sending the result data into a file. There is a problem, however, because there isn't a simple way to open such file. Of course, I can manually open folder and then the file, but it isn't very efficient. Now, to the questions part. Is there a possibility to include in the "Error Message" part of TRD a hyperlink to a file? (something similar to what we can already find in the stack trace part) If not, is there any way to add such functionality (easy opening of a file) to TRD? If not, are there any ways to expand the default reporting of VS? Thanks for any help.
