• Web scraping with Python

  - by Jack

  I'm currently trying to scrape a website that has fairly poorly-formatted HTML (often missing closing tags, no use of classes or ids so it's incredibly difficult to go straight to the element you want, etc.). I've been using BeautifulSoup with some success so far but every once and a while (though quite rarely), I run into a page where BeautifulSoup creates the HTML tree a bit differently from (for example) Firefox or Webkit. While this is understandable as the formatting of the HTML leaves this ambiguous, if I were able to get the same parse tree as Firefox or Webkit produces I would be able to parse things much more easily. The problems are usually something like the site opens a <b> tag twice and when BeautifulSoup sees the second <b> tag, it immediately closes the first while Firefox and Webkit nest the <b> tags. Is there a web scraping library for Python (or even any other language (I'm getting desperate)) that can reproduce the parse tree generated by Firefox or WebKit (or at least get closer than BeautifulSoup in cases of ambiguity).

• Mvc relative path using virtual directory..help!

  - by kevin

  When i drag and drop my image/script/css file into my view, relative path will automatically use to refer on the files. example: <link href="../../Content/style.css" rel="stylesheet" type="text/css" /> <script src="../../Scripts/jquery-min.js" type="text/javascript"></script> <img src="../../Images/logo.jpg" /> It is working fine when i host it on my root directory, but if i'm using virtual directory then only my css file able to refer correctly, the rest will return 404...as it will refer to http://{root}/Images/logo.jpg rather than http://{root}/{virtual directory}/Images/logo.jpg But why css file is working? and how to specify the relative path correctly for both root & virtual directory cases?

• Perl When is using AUTOLOAD OK?

  - by Robert S. Barnes

  In "Perl Best Practices" the very first line in the section on AUTOLOAD is: Don't use AUTOLOAD However all the cases he describes are dealing with OO or Modules. I have a stand alone script in which some command line switches control which versions of particular functions get defined. Now I know I could just take the conditionals and the evals and stick them naked at the top of my file before everything else, but I find it convenient and cleaner to put them in AUTOLOAD at the end of the file. Is this bad practice / style? If you think so why, and is there a another way to do it?

• What is needed to get Delphi back on top?

  - by Jim McKeeth

  Delphi 2009 is due in the next couple months, which is its 12th release since Turbo Pascal became Delphi in 1995. Despite continued innovation it has not returned to its level of popularity before the Inprise fiasco. Many developers with Delphi backgrounds are moving to C# and many Delphi legacy applications are being rewritten in C#, despite the fact Delphi supports .NET and in many cases the existing application could be ported without rewriting. Is it just a losing battle to compete against Microsoft's tools on their platform? Is there something Code Gear / Delphi can do now that they are under new management to regain market share? What can enthusiasts do to help? Why do you do Delphi programming? or Why are you not doing Delphi programming?

• Progressive Enhancement with box-shadow

  - by toby

  I would like to use WebKit's box-shadow css property for a little drop-down. The code would look like: .drop_down{ -webkit-box-shadow: 1px 1px 4px #888; box-shadow: 1px 1px 4px #888; } However, for browsers that do not have this capability, I would like to use borders to approximate this drop shadow, like so: .drop_down{ border-top: 1px solid #bbb; border-left: 1px solid #bbb; border-right: 2px solid #bbb; border-bottom: 2px solid #bbb; } The problem is, I don't want the border-based shadow to show up for the browsers that DO support box-shadow. I would like to avoid browser sniffing because I assume it's hard to cover all the cases. What is the simplest way to do this? I prefer a javascript-less solution, but I will consider simple javascript-based ones too.

• Best practice to use MS Excel as a database

  - by Ying

  In office, it is popular to use MS Excel to store data. In most cases, the data is structured, which means it is suitable for a database. I know peole prefer MS Excel for it is easy to change the data structure and data value. So I have an idea to use MS Excel as a database IF people follow a general rule to store data. In other words, by a best practice to use MS Excel as a database. I have thought to use MS Access to store data, but it is expensive and not popular as MS Excel. I don't mind to buy such a solution, especially when it is for .Net platform. Any ideas or suggestions are welcome.

• load/unload C dll with C# problems

  - by Goran

  I'm having problems with external native DLL. I'm working on ASP.NET 1.1 web application and have this DLL which I load through DLLImport directives. This is how I map DLL functions: [DllImport("somedllname", CallingConvention=CallingConvention.StdCall)] public static extern int function1(string lpFileName,string lpOwnerPw,string lpUserPw); [DllImport("somedllname", CallingConvention=CallingConvention.StdCall)] public static extern int function2(int nHandle); I call the dll methods and all works great, but I have problems with this DLL crashing my web site on some cases, so I would like an option to unload the dll after I use it. I found a solution at this link, but I don't have 'UnmanagedFunctionPointer' attribute in .NET 1.1 available. http://blogs.msdn.com/jonathanswift/archive/2006/10/03/Dynamically-calling-an-unmanaged-dll-from-.NET-_2800_C_23002900_.aspx Is there a way I can achieve what this guy did with his example?

• How to automatically fix MISSING reference in a dll when a referenced library is broken in VB6?

  - by systempuntoout

  What do you do when you break compatibility on a common library used by many other libraries? What i usually do is: For every dll that reference the broken one Checkout dll Checkout vbp project Open vpb project with VB6 Ide Click on References button Uncheck MISSING reference and OK Click on References button Check references and OK Click on Make dll Close project This can be a pita activity, when you have many Dll to recompile and it can be error prone because you could miss some Dll (anyway we have continuous integration that alert this cases). What's your best practice to handle this scenario?

• Can you explain to me git reset in plain english?

  - by e-satis

  I have seen interesting posts explaining subtleties about git reset. Unfortunately, the more I read about it, the more it appear that I don't understand it fully. I come from a SVN background and git is a whole new paradigm. I got mercurial easily, but git is much more technical. I think git reset is close to hg revert, but it seems there are differences. So what exactly does git reset do? Please include detailed explanations about: the options --hard, --soft and --merge; the strange notation you use with HEAD such as HEAD^ and HEAD~1; concrete use cases and workflows; consequences on the working copy, the HEAD and your global stress level. I will put a bounty on this ASAP cause it's really important and I find the git doc cryptic. Holly blessing and tons of chocolate/beer/name_your_stuff to the guy who makes a no-brainer answer :-)

• Image 8-connectivity without excessive branching?

  - by shoosh

  I'm writing a low level image processing algorithm which needs to do alot of 8-connectivity checks for pixels. For every pixel I often need to check the pixels above it, below it and on its sides and diagonals. On the edges of the image there are special cases where there are only 5 or 3 neighbors instead of 8 neighbors for a pixels. The naive way to do it is for every access to check if the coordinates are in the right range and if not, return some default value. I'm looking for a way to avoid all these checks since they introduce a large overhead to the algorithm. Are there any tricks to avoid it altogether?

• Code Golf: Beehive

  - by LiraNuna

  The challenge The shortest code by character count that will generate a beehive from user input. A beehive is defined a a grid of hexagons in a size inputted by the user as two positive numbers greater than zero (no need to validate input). The first number (W) represents the width of the beehive - or - how many hexagons are on each row. The second number (H) represents the height of the beehive - or - how many hexagons are on each column. A Single hexagon is made from three ASCII characters: _, / and \, and three lines: __ / \ \__/ Hexagons complete each other: the first column of the beehive will be 'low', and the second will be high - alternating and repeating in the same pattern forming W hexagons. This will be repeated H times to form a total of WxH hexagons. Test cases: Input: 1 1 Output: __ / \ \__/ Input: 4 2 Output: __ __ __/ \__/ \ / \__/ \__/ \__/ \__/ \ / \__/ \__/ \__/ \__/ Input: 2 5 Output: __ __/ \ / \__/ \__/ \ / \__/ \__/ \ / \__/ \__/ \ / \__/ \__/ \ / \__/ \__/ Input: 11 3 Output: __ __ __ __ __ __/ \__/ \__/ \__/ \__/ \__ / \__/ \__/ \__/ \__/ \__/ \ \__/ \__/ \__/ \__/ \__/ \__/ / \__/ \__/ \__/ \__/ \__/ \ \__/ \__/ \__/ \__/ \__/ \__/ / \__/ \__/ \__/ \__/ \__/ \ \__/ \__/ \__/ \__/ \__/ \__/ Code count includes input/output (i.e full program).

• The "Why" behind PMD's rules.

  - by James Kingsbery

  Is there a good resource which describes the "why" behind PMD rule sets? PMD's site has the "what" - what each rule does - but it doesn't describe why PMD has that rule and why ignoring that rule can get you in trouble in the real world. In particular, I'm interested in knowing why PMD has the AvoidInstantiatingObjectsInLoops and OnlyOneReturn rules (the first seems necessary if you need to create a new object corresponding to each object in a collection, the second seems like it is a necessity in many cases that return a value based on some criteria). Just to be clear, I know that I can disable these and how to do that, I'm just wondering why they are there in the first place. Sorry if there's something obvious I missed out there, but I did a Google search and SO search before posting this.

• AnkhSVN: No Versioned Parent Directories when adding a Web Site

  - by CJM

  I've recently been trying out Ankhsvn and I quite like it, and more importantly, it generally likes me. But I've hit a problem adding existing VS projects to subversion using AnkhSVN. Most Windows and Web projects are added fine, but I have a problem when I try to a Websites (as opposed to Web Applications), and in these cases I get the following error: No versioned parent directories After some googling, I've come across other people with the same problems and there have been one or two suggests for solving the problem, but non so far have worked. AnkhSVN is popular enough, and although web applications are often preferred to websites these days, I'm hoping that someone here has a ready solution available.

• How to structure Python package that contains Cython code

  - by Craig McQueen

  I'd like to make a Python package containing some Cython code. I've got the the Cython code working nicely. However, now I want to know how best to package it. For most people who just want to install the package, I'd like to include the .c file that Cython creates, and arrange for setup.py to compile that to produce the module. Then the user doesn't need Cython installed in order to install the package. But for people who may want to modify the package, I'd also like to provide the Cython .pyx files, and somehow also allow for setup.py to build them using Cython (so those users would need Cython installed). How should I structure the files in the package to cater for both these scenarios? The Cython documentation gives a little guidance. But it doesn't say how to make a single setup.py that handles both the with/without Cython cases.

• SQL Server Process Queue Race Condition

  - by William Edmondson

  I have an order queue that is accessed by multiple order processors through a stored procedure. Each processor passes in a unique ID which is used to lock the next 20 orders for its own use. The stored procedure then returns these records to the order processor to be acted upon. There are cases where multiple processors are able to retrieve the same 'OrderTable' record at which point they try to simultaneously operate on it. This ultimately results in errors being thrown later in the process. My next course of action is to allow each processor grab all available orders and just round robin the processors but I was hoping to simply make this section of code thread safe and allow the processors to grab records whenever they like. So Explicitly - Any idea why I am experiencing this race condition and how I can solve the problem. BEGIN TRAN UPDATE OrderTable WITH ( ROWLOCK ) SET ProcessorID = @PROCID WHERE OrderID IN ( SELECT TOP ( 20 ) OrderID FROM OrderTable WITH ( ROWLOCK ) WHERE ProcessorID = 0) COMMIT TRAN SELECT OrderID, ProcessorID, etc... FROM OrderTable WHERE ProcessorID = @PROCID

• What to do when GMap Satellite imagery is unavailable

  - by robstenson

  Hello-- is it possible to programmatically detect with the google maps api (javascript, v2) when satellite imagery is unavailable at a certain zoom level? I am creating some maps automatically and setting them to a certain zoom level, but in a few cases there is no satellite imagery available at that level, in which case I'd like to automatically back up a zoom level. Does the api expose some way of determining this lack of imagery? So far the only thing I can think of is trying to find out, with javascript, whether or not the image requests that the api makes are failing, and then reacting based on those failed image requests, but I can't really get it to work... and it seems a little inelegant. Thanks for your help!

• Supporting different locale regions using Rails i18n

  - by Olly

  I'm using the standard Rails I18n API to localise some of our views. This is working really well, but we now have a few use cases for regional changes to the en locale. The API guide mentions that this isn't supported directly, and other plugins should be used. However, I'm wondering whether there's a simpler way to do this. I already have en.yml, so in theory I could just create en-AU.yml and en-US.yml which are effectively clones of en.yml but with a few regional changes applied. I could then add additional English - American and English - Australian options to our configuration which would map to the new region-specific locales and allow users to use a region-specific locale. The only problem I can think of with this is that it isn't DRY -- I would have duplicate translations for all common English words. I can't see a way around this. Are there any other disadvantages to this approach, or should I just bite the bullet and dive into one of the plug-ins such as Globalize2 instead?

• How do I get the displayname of the logged in user in EWS?

  - by tig

  Exchange Autodiscovery will give me the user's Display Name via the UserSettingName.UserDisplayName property. However, in cases where autodiscovery fails and connection needs to be done manually I can't figure out how to get the DisplayName. I tried this, but I just get the users' email address: _service = new ExchangeService(); _service.Credentials = new System.Net.NetworkCredential(exchangeSettings.EmailAddress, exchangeSettings.Password); _service.Url = new Uri(exchangeSettings.ExternalEwsUrl); NameResolutionCollection resolvedNames = _service.ResolveName(exchangeSettings.EmailAddress); exchangeSettings.UserDisplayName = resolvedNames.First().Mailbox.Name; Thanks

• Displaying rows in multiple columns

  - by zizo

  Not sure if this is doable using sql alone or not, but here is the problem. I have a weird requirement that data needs to be displayed in columns so users can compare data quickly! Here is what the result set looks like right now CustomerID Company Active 001 ATT Y 002 ATT N 003 ATT Y 001 VZ Y 002 VZ N 003 VZ Y 001 TM Y 002 TM Y 003 TM Y Now this is how they want to see it CustomerID Company Active Company Active Company Active 001 ATT Y VZ Y TM Y 002 ATT N VZ N TM Y 003 ATT Y VZ Y TM Y Assumptions: This could be a pretty long table, that's why they want to see all companies on one row, rather than needing to scroll down to see if active or not. Nummber of companies is between 1-3 in most cases Any help is appreciated. Thanks!

• How to check if an apply-template filled variable is a string or (possibly) empty node in XSLT?

  - by calavera.info

  I need a test which would evaluate to true in two cases: There is a string inside which contains any non white space characters There is any node (which can be possibly empty) on a variable that is filled with apply-template call result. I tried test="normalize-space($var)" but this doesn't cover the empty tag possibility. I also tried simply this: test="$var" but this evaluate to true even for white space only strings. By the way "$var/*" produces an error "Expression ...something I don't remember... node-set" which is I think because of apply-template variable instantiation. Is there any (which means even multi level decision) solution for this? EDIT: I forgot to say that it's for XSLT 1.0 and preferably without any exslt extensions or similar.

• What's the right way to kill child processes in perl before exiting?

  - by rarbox

  I'm running an IRC Bot (Bot::BasicBot) which has two child processes running File::Tail but when exiting, they don't terminate. So I'm killling them using Proc::ProcessTable like this before exiting: my $parent=$$; my $proc_table=Proc::ProcessTable->new(); for my $proc (@{$proc_table->table()}) { kill(15, $proc->pid) if ($proc->ppid == $parent); } It works but I get this warning: 14045: !!! Child process PID:14047 reaped: 14045: !!! Child process PID:14048 reaped: 14045: !!! Your program may not be using sig_child() to reap processes. 14045: !!! In extreme cases, your program can force a system reboot 14045: !!! if this resource leakage is not corrected. What else can I do to kill child processes? The forked process is created using the forkit method in Bot::BasicBot.

• Collision detection, alternatives to "push out"

  - by LaZe

  I'm moving a character (ellipsoid) around in my physics engine. The movement must be constrained by the static geometry, but should slide on the edges, so it won't be stuck. My current approach is to move it a little and then push it back out of the geometry. It seems to work, but I think it's mostly because of luck. I fear there must be some corner cases where this method will go haywire. For example a sharp corner where two walls keeps pushing the character into each other. How would a "state of the art" game engine solve this?
