• Is it possible to change the pane locations in Chrome Developer Tools?

  - by T.J. Crowder

  When debugging browser-based apps using Google Chrome's Developer Tools, is there a way to change the locations of the various panes? E.g., the Watch Expressions, the Call Stack, the code pane, etc.? The defaults are okay (console at bottom, code pane upper left, a column of Watch Expressions, Call Stack, Scope Vars, etc. in the upper right), but I'd rather swap things around a bit of it's possible. There doesn't seem to be anything to grab (other than for sizing) and I haven't found a way in my searching so far, but there are (still) some things about Chrome's options that aren't ... well-advertised in the UI, shall we say :-), especially around developer tools.

• mysql - filtering a list against keywords, both list and keywords > 20 million records

  - by threecheeseopera

  I have two tables, both having more than 20 million records; table1 is a list of terms, and table2 is a list of keywords that may or may not appear in those terms. I need to identify the terms that contain a keyword. My current strategy is: SELECT table1.term, table2.keyword FROM table1 INNER JOIN table2 ON table1.term LIKE CONCAT('%', table2.keyword, '%'); This is not working, it takes f o r e v e r. It's not the server (see notes). How might I rewrite this so that it runs in under a day? Notes: As for server optimization: both tables are myisam and have unique indexes on the matching fields; the myisam key buffer is greater than the sum of both index file sizes, and it is not even being fully taxed (key_blocks_unused is ... large); the server is a dual-xeon 2U beast with fast sas drives and 8G of ram, fine-tuned for the mysql workload.

• How to remove svn folders over FTP on Windows hosting

  - by Loftx

  Hi there, I've accidentally copied a large part of a folder tree from my SVN working copy to my shared Windows web host via FTP. The site is now littered with .svn directories and and I need some way of cleaning them. The only access I have to the server is via FTP, or by running a script on the server. Does any one have a script which can be run remotely to remove the files over FTP from my development machine (any language Windows/Linux is fine) or a script in ASP, ASP.net or PHP I can run directly on the Windows server to remove these directories? Thanks, Tom

• SQL server virtual memory usage and perofrmance

  - by user365035

  Hello, I have a very large DB used mostly for analytics. The performance overall is very sluggish. I just noticed that when running the query below, the amount of virtual memory used greatly exceed the amount of physical memory available. Currently, phsycial memory is 10GB (10238 bytes) where as the virtual memory returns significantly more 8388607 bytes. That seems really wrong, but I'm at a bit of a loss on how to proceed. USE [master]; GO select cpu_count , hyperthread_ratio , physical_memory_in_bytes / 1048576 as 'mem_MB' , virtual_memory_in_bytes / 1048576 as 'virtual_mem_MB' , max_workers_count , os_error_mode , os_priority_class from sys.dm_os_sys_info

• Garbage Collection leak? Scripting Bridge leak?

  - by Y.Vera

  Hello everyone! I'm always really picky about memory leaks and I cannot understand why my garbage collected application leaks. My code is entirely memory-managed and it runs great without garbage collection, not a single leak. However, as soon as I turn on garbage collection it leaks! Just to prove a point, why does this leak in a garbage collected app? (place this dummy code at applicationDidFinishLaunching:) NSOpenPanel *panel = [NSOpenPanel openPanel]; [panel beginSheetModalForWindow:window completionHandler:^(NSInteger result) {NSBeep();}]; Also, is there a way to prevent leaks in apps (garbage collected or otherwise) that use Scripting Bridge? it seems as if they all leak, even the sample ones in xcode. Thanks everybody!

• Can I access the function body of an event listener using nodeJS jsdom

  - by Zhami

  I am using jsdom with nodeJS. I load in a large HTML document, and am using jQuery to navigate the DOM. I have a case where I have an element, and I need to access the function body of an event listener (onclick). The event listener was added in the source HTML: <a href="#" onclick="javascript:window.open('http://<rest-of-url>'); return false;"></a> The onclick attribute of the DOM element is undefined. btw: what I really want to do is get the URL (please note that <rest-of-url> is not what is in the source, a real URL spec is there) that is specified in the source.

• Deploying my flex application

  - by Vatsala

  Hi, I am doing some trial testing awith Amazon ec2 boxes, deploying flex apps running on top of restlet powered webservices. I have this problem - Everytime i deploy the app to the cloud, I'm having to hardcode the IP address of the server into the ActionScript/MXML files (http://72.93.48.39:8080/xxx/abc/) and for certain reasons, i am forced to choose a different IP everytime. and i think its really not the right way to deploy the application. I would like to know what other people do in such scenarios? On thinking about it, i thought i could make it pickup values from the HTMLVars of the HTML wrapper. but that again has to be edited everytime again and again. will it be possible to be able to supply these values : server's ip address, server's port number(in case its not 8080 on some machine) at build time? if so can anyone give me a barbones sample build.xml just as an example?

• Control margins of an automatically generated content presenter in Windows Phone Panorama Control

  - by Maxim V. Pavlov

  I am building an MVVM Panorama Windows Phone 7 application. At some point of Panorama Item's layout I get a bottom margin of a panorama header box, that moves my content too far down. Is there a way I can set a bottom margin of a ContentPresenter, that is generated to hold the controls, defined in the Panorama.HeaderTemplate? Here is my layout list in Silverlight Spy: In case the screen shot is not readable, here is a large version: http://bit.ly/rBvNp8 Something generates a 26 points bottom margin for a header box (probably the control's code, that handles a layout). How can I control this value? I need it to be set to 0.

• Modern Web Development + General question

  - by ritu

  I have been given a nasty wake up a while ago when I discovered that my 10 years of experience was really equivalent of about 4 (got trapped in a big company doing the same thing over and over without realizing it) and is now paying a huge price. Question 1: I did servlets/JSP programming back in the day (2001-2003). Since then there have been libraries like GWT, YUI, etc. Is JSP still the preferred way of building web apps using Java? Question 2: Because I enjoyed what I was doing and needed to pay the bills, I didn't realize that the ground below me has shifted. How do avoid this in the future? My years of C system programming doesn't seem to matter a lot now to the young guys who talk about design patterns.

• Hopefully simple topic to spark some good opinions, Question is MySQL or SQL Server???

  - by magellings

  I'm beginning development of a website and a high priority is for it to be extremely optimized, quick responses, etc. There will ultimately end up being large amounts of rows in the main tables (millions), so scalability is also important. It will need to use a database on the back-end for data storage and my web hosting service supports either MySQL or Sql Server. This website will be developed with .NET ASP.NET MVC with NHibernate (hopefully it can run in medium trust mode, as that is a requirement of my web hosting and reflection requirements of NHibernate may be problematic, maybe someone has a comment on this too). I'd also prefer to use the database that will require the least attention in regards to management. I don't want to have to be a DBA here. :) I wanted to through this topic out to the public to see what the community thinks? So MySQL or Sql Server, generally, which one would be better to use?

• Where can I find a proper JavaScript beautifier

  - by Ernelli

  I have used http://jsbeautifier.org/ successfully using Rhino and ant, but the problem is that it is not deterministic. If you run the beautifier twice on a file the result is different from each time, e.g. each pass inserts additional array intendation on some lines. I have spent a lot of time debugging the code in beautify.js and have made some workarounds for comment handling, but the array indentation bug is annoying. Is there a correct and properly working JS code formatter anywhere that can be used as part of a source code indentation verification system? EDIT I have now tested with preserve-array-formating disabled, and it seems that it solves the problem. Too bad, since preserve-array-formating is quite useful with large array constructs.

• Advice about testing an application before release?

  - by Troy

  I would like to get some tips from peer developers about how you go about testing an application you developed, prior to release to QA. Keep in mind, this is a small scale application (requirements are verbal), and so doing formal testing processes wont work, especially, since your boss told you to develop this app quick, push it out the door. Despite the time restraints, I would like to make sure it is bug free, however, numerous times in the past, I have had the app sent back to me because clicking the "Reset" button, messes up the other controls alignment etc. I know there are people out there that develop small scale apps fast, and send them out with minimal bugs. How can I achieve that? I researched this post, but it didnt quite answer my question. Testing your code before releasing to QA

• How to run an executable as a system service?

  - by byanity

  I've got a file and data distribution application written in .NET 2.0 I've written similar to Steam. This application will need to run in Windows 7 and will need to be able to run and install applications that require administrator rights. However the users will not have admin rights. My thought was to run the application as a Local System Service. I figured by doing this the application could perform admin rights actions (registry edits, launching apps, etc) when the user isn't an admin. Are my assumptions correct? What steps do I need to take to have this app install as a Local System Service? An Administrator will be installing the application but it will be run by a user without Administrator rights. Thanks in advance!

• Firefox 17 and CSS borders based triangles = crap

  - by Adeher

  Like many front-end devs, I've been using the border trick to render triangles in CSS. http://apps.eky.hk/css-triangle-generator/ this generator helps with the technique. Today, like every week (almost), the Firefox team released a new version without any clear changelog on the rendering engine. Now we can see an ungraceful gray border around those triangles. I haven't found a trick to get rid of it yet. On top of that, before Firefox 17, when people were complaining about how aliased those triangles looked, an additional trick was to set the border-style property to "dashed" instead of solid. Using firebug on the triangle generator, you can quickly see how it shows up now, and cry yourself to death. I hope a more brillant front-end dev than myself will find a fix for this and share it here. Thanks

• Creating a gallery in Rails

  - by raphael_turtle

  I'm creating a simple site with a gallery. I have a photos model which has a page for each photo with it's info and an image. I'm unsure how to create a gallery from the photo's. The gallery model has_many photos, the photos model has_and_belongs_to_many galleries. I thought of adding a gallery.title field on each photo page so I'd have a list of photo's for each gallery then display them in a view. Is this a good way to make a gallery? (I've looked through the code on some gallery apps on github, but most are outdated are too complicated for my needs.)

• Integrating my new program with Windows

This would require me to Change something about my XP installation to show my program in the dropdown list Change the program so that it knows to open the selected file and run the parsing. What do you call these things, and how is it done? I don't know what to search for...

• What is the maximum number of controls that a VBA form can hold?

  - by Lunatik

  I'm currently building an Excel 2003 app that requires a horribly complex form and am worried about limitations on the number of controls. It currently has 154 controls (counted using Me.Controls.Count - this should be accurate, right?) but is probably only about a third complete. The workflow really fits a single form, but I guess I can split it up if I really have to. I see evidence in a Google search that VB6 (this usually includes VBA) has a hard limit of 254 controls in a form. However, I created a dummy form with well over 1200 controls which still loaded and appeared to work just fine. I did get some 'out of memory' errors when trying to add specific combinations of controls though, say 800 buttons and 150 labels, leading me to think that any limit might be affected by the memory requirements of each type of control. Does anyone have any information that might help ensure that I or, more importantly, other users with differing environments don't run into any memory issues with such a large form?

• Can I override DropLocation target to avoid network latency?

  - by Chad

  In Team Build 2008, the Drop Location for a build is no longer specified in the .proj file, and instead is stored in the database and maintained in the GUI tool. The GUI tool only accepts a network path as a drop location (i.e. \\server\share) and will not accept a local path. Our build server also hosts the dropped files, so it seems that forcing a file copy operation to go through the network share introduces a lot of lag time when copying a large number of files. I would like to override this feature so that I can specify a local directory for drop location, but I can't figure out how.

• Add CSS Class to link based on Character Count with jquery

  - by Wes

  I have links that load dynamically onto a background to make them look like buttons. Some of the links take up two lines and some of the links take up 1 line. Eithe way they need to be vertically centered. My plan to to append a class based on the number of characters and then adjust the padding from there. So if the link's text is 25 characters (including spaces) or less - append class 'small' if the link's text is greater than 25 characters - append class 'large' How would I go about doing this with jQuery?

• Comment out a python code block

  - by gbarry

  Is there any mechanism to comment out large blocks of Python code? Right now the only ways I can see of commenting out code are to either start every line with a #, or to enclose the code in """ (triple quotes), except that actually makes it show up in various doc tools. Edit--After reading the answers (and referring to the "duplicate"), I have concluded the correct answer is "No". One person said so, and the rest lectured us about editors. Not a bad thing, but I feel it's important to put the answer at the top.

• Evaluation of jQuery function variable value during definition of that function

  - by thesnail

  I have a large number of rows in a table within which I wish to attach a unique colorpicker (jQuery plugin) to each cell in a particular column identified by unique ids. Given this, I want to automate the generation of instances of the colorpicker as follows: var myrows={"a","b","c",.....} var mycolours={"ffffff","fcdfcd","123123"...} for (var i=0;i<myrows.length;i++) { $("#"+myrows[i]+"colour").ColorPicker({flat: false, color: mycolours[i], onChange: function (hsb, hex, rgb) { $("#"+myrows[i]+"currentcolour").css('backgroundColor', '#' + hex); } }); Now this doesn't work because the evaluation of the $("#"+myrows[i]+"currentcolour") component occurs at the time the function is called, not when it is defined (which is want I need). Given that this plugin javascript appends its code to the level and not to the underlying DOM component that I am accessing above so can't derive what id this pertains to, how can I evaluate the variable during function declaration/definition? Thanks for any help/insight anyone can give. Brian.

• What is the benefit of using int instead of bigint in this case?

  - by Yeti

  (MYSQL n00b) I have 3 tables: id = int(10), photo_id = bigint(20) PHOTO records limited to 3 million PHOTO: +-------+-----------------+ | id | photo_num | +-------+-----------------+ | 1 | 123456789123 | | 2 | 987654321987 | | 3 | 5432167894321 | +-------+-----------------+ COLOR: +-------+-----------------+---------+ | id | photo_num | color | +-------+-----------------+---------+ | 1 | 123456789123 | red | | 2 | 987654321987 | blue | | 3 | 5432167894321 | green | +-------+-----------------+---------+ SIZE: +-------+-----------------+---------+ | id | photo_num | size | +-------+-----------------+---------+ | 1 | 123456789123 | large | | 2 | 987654321987 | small | | 3 | 5432167894321 | medium | +-------+-----------------+---------+ Both COLOR and SIZE tables will have several million records. Q1: Is it better to change photo_num on COLOR and SIZE to int(10) and point it to PHOTO's id? Right now I use these: (PHOTO is no where in the picture) SELECT * from COLOR WHERE photo_num='xxx'; SELECT * from SIZE WHERE photo_num='xxx'; Q2: How will the SELECT query look if PHOTO id was used in COLOR, SIZE?

• Loading and managing reference data in Rails

  - by jonnii

  Most of the apps I've worked on have had some kind of reference data stored in the database, for example categories, zipcodes, area codes etc... this is information that's going to change very infrequently. Most of the time you want to load some kind of display name, and that's it. Currently this isn't causing me too many headaches, it's easy to :include the models I need when doing my queries, but going forward it causes a lot of query noise. Ideally I'd like to load the reference data when the app starts and when referencing it in queries it'll load from the cache instead of going to the database. What's the best way to manage this?
