• Chrome and its Spellcheck -- How Hard Would This Be To Implement

  - by bobber205

  From a programmer's perspective. The dictionary in chrome, Google's "own" browser, does not have the same dictionary as their search engine. Countless times I have right clicked on a poorly misspelled word only to have no correct spelling appear. I Google the word and almost 100% of the time it knows what I was trying to type. :) I realize there are probably very good reasons for this, but why can't Chrome simply Google for a word when you right click on it when it can't find a correct spelling. I am sometimes a bad speller and it would be really nice if the spell check in Chrome at least utilized Google's landmark product to provide more accurate word spelling lookups. How hard must this be to implement or are there other reasons you think they are not?

• python regex for repeating string

  - by Lars Nordin

  I am wanting to verify and then parse this string (in quotes): string = "start: c12354, c3456, 34526;" //Note that some codes begin with 'c' I would like to verify that the string starts with 'start:' and ends with ';' Afterward, I would like to have a regex parse out the strings. I tried the following python re code: regx = r"V1 OIDs: (c?[0-9]+,?)+;" reg = re.compile(regx) matched = reg.search(string) print ' matched.groups()', matched.groups() I have tried different variations but I can either get the first or the last code but not a list of all three. Or should I abandon using a regex?

• Regex for Searching for Text Not Preceeded By a Specific String

  - by James

  Hi, I am working on a web site with several other developers and we have had problems where people commit JavaScript code with AJAX calls that use URL's relative to the site root. An example would be /Home/Index which will not work if the site is hosted in a virtual directory. To get round the problem we use a $.url() method to convert it to a full path, e.g. $("#container").load($.url("/Home/Index")) I am trying to write a unit test that will search each JavaScript file and find places where the $.url method is not being used. The only problem is that I cannot seem to write a regex expression to do this. I have tried the following: (?!\$\.url\()"(/\w*)+" But this does not work. I cannot find a way to say that I don't want the $.url in front. Does anyone know if this is possible? Note that I need regular expressions that are compatible with .NET Thanks.

• Xcodebuild failing to pick up environment values from project file?

  - by egrunin

  I'm using Xcode 3.2.6, MacOSX. I have a globally visible environment setting: ICU_SRC=~/Documents/icu/source This really is an environment setting, it's set at login time. When I open up Terminal, it's there. In my project, under Header Search Paths I've added this: $(ICU_SRC)/i18n $(ICU_SRC)/common These expand correctly when I compile inside the IDE. When I look at the build results, I see this: -I/Users/eric.grunin/Documents/icu/source/i18n -I/Users/eric.grunin/Documents/icu/source/common When I build from the command line, however, it fails. What I see is this: -I/i18n -I/common Here's the command I'm using to compile: /usr/bin/env -i xcodebuild -project my_project.xcodeproj -target "my_program" -configuration Release -sdk macosx10.6 build What am I doing wrong? Edited to add: Apple explains Setting environment variables for user processes

• Is it a solvable problem to generate a regular expression that matches some input set?

  - by Roman

  I provide some input set which contains known separated number of text blocks. I want to make a program that automatically generate 1 or more regular expressions each of which matches every text block in the input set. I see some relatively easy ways to implement a brute-force search. But I'm not an expert in compilers theory. That's why I'm curious: 1) is this problem solvable? or there are some principle impossibility to make such algorithm? 2) is it possible to achieve polynomial complexity for this algorithm and avoid brute forcing?

• Replicating iPhone Calendar View Lame?

  - by John Wright

  I am building an iPhone app that will need to display info primarily in a calendar view. Users will need to be able to search for entries and view them by day, month or in a list view. It seems like the built-in calendar type interface is ideal for my app. So I could build a similar calendar with 3 buttons at the bottom for list/day/month view as well as a button for today, in short a very similar interface to the built in iPhone calendar with different colors primarily. However, if I replicate it am I a) a lame copycat for replicating the built-in interface or smart for using a well-known iPhone metaphor and b) in danger of having my app rejected?

• Software Protection: Shuffeling my application?

  - by Martijn Courteaux

  Hi, I want to continue on my previous question: http://stackoverflow.com/questions/3007168/torrents-can-i-protect-my-software-by-sending-wrong-bytes Developer Art suggested to add a unique key to the application, to identifier the cracker. But JAB said that crackers can search where my unique key is located by checking for binary differences, if the cracker has multiple copies of my software. Then crackers change that key to make them self anonymous. That is true. Now comes the question: If I want to add a unique key, are there tools to shuffle (a kind of obfuscation) the program modules? So, that a binary compare would say that the two files are completely different. So they can't locate the identifier key. I'm pretty sure it is possible (maybe by replacing assembler blocks and make some jumps). I think it would be enough to make 30 to 40 shuffles of my software. Thanks

• How can I change the filename of a shared library after building a program that depends on it?

  - by ZorbaTHut

  I have a program that depends on a shared library it expects to find deep inside a directory structure. I'd like to move that shared library out and into a better place. On OS X, this can be done with install_name_tool. I'm unable to find an equivalent for Linux. For reference, readelf -d myprogram spits out the following paraphrased output: Dynamic section at offset 0x1e9ed4 contains 30 entries: Tag Type Name/Value 0x00000001 (NEEDED) Shared library: [this/is/terrible/library.so] 0x00000001 (NEEDED) Shared library: [libGL.so.1] 0x00000001 (NEEDED) Shared library: [libGLU.so.1] 0x00000001 (NEEDED) Shared library: [libstdc++.so.6] and I would like to errata "this/is/terrible/library.so" to be "shared/library.so". I know about RPATH and it isn't what I'm looking for, I don't need to change search paths globally.

• Dynamic Like Statement in SQL

  - by Peter McElhinney

  Hey there! I've been racking my brain on how to do this for a while, and i know that some genius on this site will have the answer. Basically i'm trying to do this: SELECT column FROM table WHERE [table][column] LIKE string1 OR [table][column] LIKE string2 OR [table][column] LIKE string3... for a list of search strings stored in a column of a table. Obviously I can't do a like statement for each string by hand because i want the table to be dynamic. Any suggestions would be great. :D EDIT: I'm using MSSQL :(

• How secure are GUIDs in terms of predictability?

  - by ssg

  We're using .NET's Guid.NewGuid() to generate activation codes and API keys currently. I wonder if that poses a security problem since their algorithm is open. .NET Guid uses Win32 CoCreateGuid and I don't know it's internals (possibly MAC address + timestamp?). Can someone derive a second GUID out of the first one, or can he hit it with some smart guesses or is the randomness good enough so search space becomes too big? Generating random keys have the problem of collision, they need a double check before adding to a database. That's why we stuck with GUIDs but I'm unsure about their security for these purposes. Here are the 4 consecutive UUIDGEN outputs: c44dc549-5d92-4330-b451-b29a87848993 d56d4c8d-bfba-4b95-8332-e86d7f204c1c 63cdf958-9d5a-4b63-ae65-74e4237888ea 6fd09369-0fbd-456d-9c06-27fef4c8eca5 Here are 4 of them by Guid.NewGuid(): 0652b193-64c6-4c5e-ad06-9990e1ee3791 374b6313-34a0-4c28-b336-bb2ecd879d0f 3c5a345f-3865-4420-a62c-1cdfd2defed9 5b09d7dc-8546-4ccf-9c85-de0bf4f43bf0

• Finding the best jquery plugins

  - by Lan

  Is there a resource for finding the "best" jquery plugins, or at least just the most used ones? For example, I wanted to find a menu jquery plugin but when I goto the jquery website there are so many to look through and I don't see a way to see how popular each one is. For ruby there's the http://ruby-toolbox.com/ which lists many plugins, how popular they are, info about them, etc. Is there something similar or at least some way to filter through all the jquery plugins? EDIT 1: To shed some more light on this - the "most popular" link on the jquery page is useless. I can't find a way to search through it but even worse, the ratings don't seem to mean much. Ex - the first item, in other words the most popular plugin in that list has 5 stars and TWO votes. Doesn't seem like a very reliable resource to me.

• How to Invoke iPhone Maps for Directions with Current Location as Start Address

  - by eriaac

  Hi all. I know it's possible to start the iPhone maps application by calling openURL on a google maps URL with parameters saddr and daddr with location strings or LatLong (see ex. below), but I'm wondering if it's possible to make the start address be the "Current Location" maps bookmark so that I can use the maps app's location handling code. My Google search has been pretty fruitless. ex: [[UIApplication sharedApplication] openURL:[NSURL URLWithString:[NSString stringWithFormat: @"http://maps.google.com/maps?saddr=%@&daddr=%@", myLatLong, latlong]]]; Except with something to invoke the current location bookmark in place of myLatLong. Thanks!

• can QuickGraph support these requirements? (includes database persistence support)

  - by Greg

  Hi, Would QuickGraph be able to help me out with my requirements below? (a) want to model a graph of nodes and directional relationships between nodes - for example to model web pages/files linked under a URL, or modeling IT infrastructure and dependencies between hardware/software. The library would include methods such as * Node.GetDirectParents() //i.e. there could be more than one direct parent for a node * Node.GetRootParents() //i.e. traverse the tree to the top root parent(s) for the given node * Node.GetDirectChildren() * Node.GetAllChildren() (b) have to persist the data to a database - so it should support SQL Server and ideally SQLite as well. If it does support these requirement then I'd love to hear: any pointers to any parts of QuickGraph to dig into? what is the best concept re it's usage in terms of how to use database persistence - is it a simpler design to assume every search/method works directly on the database, or does QuickGraph support smarts to be able to work in memory and the "save" to database all changes at an appropriate point in time (e.g. like ADO.net does with DataTable etc) Thanks in advance

• What's the requests/second standard for scraping websites?

  - by feydr

  This was the closest question to my question and it wasn't really answered very well imo: http://stackoverflow.com/questions/2022030/web-scraping-etiquette I'm looking for the answer to #1: How many requests/second should you be doing to scrape? Right now I pull from a queue of links. Every site that gets scraped has it's own thread and sleeps for 1 second in between requests. I ask for gzip compression to save bandwidth. Are there standards for this? Surely all the big search engines have some set of guidelines they follow in regards to this.

• does windows 7 bluetooth stack and API support connection of headsets

  - by markh44

  We need to write code to search for, pair and connect to a bluetooth headset with Windows 7 Embedded. Once connected the headset will be used as a normal windows audio device. We fully control what software is installed on the system so conflicting stacks and similar concerns are not a problem. We would however like to minimize as far as possible installing extra software such as 3rd party stacks. Therefore my question is: can the built in windows 7 bluetooth stack and C++ API alone be used to create the functionality we need?

• 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?

• Using GET instead of POST to delete data behind authenticated pages

  - by Matt Spradley

  I know you should use POST whenever data will be modified on a public website. There are several reasons including the fact that search engines will follow all the links and modify the data. My question is do you think it is OK to use GET behind authenticated pages in something like an admin interface? One example would be a list of products with a delete link on each row. Since the only way to get to the page is if you are logged in, is there any harm in just using a link with the product ID in the query string?

• Caching the repository index in m2eclipse

  - by Titi Wangsa bin Damhore

  everytime i start with a fresh new workspace, m2eclipse downloads nexus-maven-repository-index.gz from the maven central repository. this is good. but, some times, i just want to start a new workspace, and not wait for it to download, it tried copying the whole .metadata directory from an old workspace to the new one, but the list of maven artifacts are still empty. is there a way i can cache it? or at least download the file once, and the copy/extract/repackage it so that m2eclipse thinks it has already downloaded it and allows me to search for maven artifacts. or a short version of the question where and in what format is the "nexus-maven-repository-index.gz" file stored in the workspace?

• Question about the lifecycle of a simple Android application

  - by jul

  Hi, I've got a simple application with 3 activities: -the first contains a search box which calls a web service and show the results (restaurants) below in a listview -when a restaurant is clicked another activity is started showing the description of the restaurant and a button "show map" -when the button "show map" is clicked, guess what, the map is shown in a third activity. All the data is loaded in the first activity by a web service (restaurant descriptions and coordinates), and data required by each activity is passed in a bundle using "intent.putExtra". Now everything seems to run smoothly when clicking on the back button (eg. clicking on the back button from the map resumes the "restaurant description" activity with all data set properly), while I haven't done anything about the lifecycle yet. Why? Are all variables saved automatically? Should I use onSaveInstanceState() and onRestoreInstanceState() anyway? Thanks Jul

• combination of open source licenses

  - by Nicola Montecchio

  Hi I'm about to release some software as open source. It uses Lucene (Apache license) and jopt simple (MIT license). Are there any constraints on the license that I am going to apply to my own software? In particular, it is an adaptation of Lucene for performing content-based search on audio (so, many classes are inherited and in one case copied with a little modification). It only uses jopt simple for handling command line arguments (i.e. no modification at all, just "import" and "new OptionParser..."). Thanks for your help Nicola Montecchio

• Can this rectangle to rectangle intersection code still work?

A search on the internet came up with this one-liner (WOOT!), but I don't understand how to write it in Javascript, it seems to be written in an ancient form of C++. Can this thing still work? Can you make it work? struct { LONG left; LONG top; LONG right; LONG bottom; } RECT; bool IntersectRect(const RECT * r1, const RECT * r2) { return ! ( r2->left > r1->right || r2->right left || r2->top > r1->bottom || r2->bottom top ); }

• link_to for calling an action, instead of a button_to

  - by Brian Roisentul

  I'd like to call an action with a link_to button without being redirected to another page(I don't want ajax). For you to have an idea, I'm trying to accomplish a sort "link button" in a search page. So, when the link is clicked, the page should be refreshed showing the list ordered as I tell it in the action. If I do the following in my view, it will ask me for a template called as the action, and I don't want it: <%= link_to 'M&Aacute;S RELEVANTES', search_filter_relevance_path %> My routes file looks like this: map.search_filter_relevance "/anuncios/buscar", :controller => 'announcements', :action => 'search_filter_relevance' And my controller looks like this(I haven't developed the functionality yet): def search_filter_relevance end Any help on this will be appreciated.
