• F# constructor syntax - overiding and augmenting new

  - by Benjol

  I have a non-disposable class with Open/Close syntax that I'd like to be able to use, so I'm trying to inherit from it, and work the Open into the new and the Close into Dispose. The second part is ok, but I can't work out how to do the Open: type DisposableOpenCloseClass(openargs) = inherit OpenCloseClass() //do this.Open(openargs) <-- compiler no like interface IDisposable with member this.Dispose() = this.Close() (cf. this question which I asked a long time ago, but I can't join the dots to this one)

  - by kim

  I have the following that I retreive the title of each url from an array that contains a list of urls. require 'rubygems' require 'nokogiri' require 'open-uri' @urls = ["http://google.com", "http://yahoo.com", "http://rubyonrails.org"] @found_titles = Array.new @found_titles[0] = Nokogiri::HTML(open("#{@urls[0]}")).search("title").inner_html #this can go on forever...but #@found_titles[1] = Nokogiri::HTML(open("#{@urls[1]}")).search("title").inner_html #@found_titles[2] = Nokogiri::HTML(open("#{@urls[2]}")).search("title").inner_html puts "#{@found_titles[0]}" How should i form a loop method for this so i can get the title even when the list in @url array gets longer.

• Problems with with A* algorithm

  - by V_Programmer

  I'm trying to implement the A* algorithm in Java. I followed this tutorial,in particular, this pseudocode: http://theory.stanford.edu/~amitp/GameProgramming/ImplementationNotes.html The problem is my code doesn't work. It goes into an infinite loop. I really don't know why this happens... I suspect that the problem are in F = G + H function implemented in Graph constructors. I suspect I am not calculate the neighbor F correclty. Here's my code: List<Graph> open; List<Graph> close; private void createRouteAStar(Unit u) { open = new ArrayList<Graph>(); close = new ArrayList<Graph>(); u.ai_route_endX = 11; u.ai_route_endY = 5; List<Graph> neigh; int index; int i; boolean finish = false; Graph current; int cost; Graph start = new Graph(u.xMap, u.yMap, 0, ManhattanDistance(u.xMap, u.yMap, u.ai_route_endX, u.ai_route_endY)); open.add(start); current = start; while(!finish) { index = findLowerF(); current = new Graph(open, index); System.out.println(current.x); System.out.println(current.y); if (current.x == u.ai_route_endX && current.y == u.ai_route_endY) { finish = true; } else { close.add(current); neigh = current.getNeighbors(); for (i = 0; i < neigh.size(); i++) { cost = current.g + ManhattanDistance(current.x, current.y, neigh.get(i).x, neigh.get(i).y); if (open.contains(neigh.get(i)) && cost < neigh.get(i).g) { open.remove(open.indexOf(neigh)); } else if (close.contains(neigh.get(i)) && cost < neigh.get(i).g) { close.remove(close.indexOf(neigh)); } else if (!open.contains(neigh.get(i)) && !close.contains(neigh.get(i))) { neigh.get(i).g = cost; neigh.get(i).f = cost + ManhattanDistance(neigh.get(i).x, neigh.get(i).y, u.ai_route_endX, u.ai_route_endY); neigh.get(i).setParent(current); open.add(neigh.get(i)); } } } } System.out.println("step"); for (i=0; i < close.size(); i++) { if (close.get(i).parent != null) { System.out.println(i); System.out.println(close.get(i).parent.x); System.out.println(close.get(i).parent.y); } } } private int findLowerF() { int i; int min = 10000; int minIndex = -1; for (i=0; i < open.size(); i++) { if (open.get(i).f < min) { min = open.get(i).f; minIndex = i; System.out.println("min"); System.out.println(min); } } return minIndex; } private int ManhattanDistance(int ax, int ay, int bx, int by) { return Math.abs(ax-bx) + Math.abs(ay-by); } And, as I've said. I suspect that the Graph class has the main problem. However I've not been able to detect and fix it. public class Graph { int x, y; int f,g,h; Graph parent; public Graph(int x, int y, int g, int h) { this.x = x; this.y = y; this.g = g; this.h = h; this.f = g + h; } public Graph(List<Graph> list, int index) { this.x = list.get(index).x; this.y = list.get(index).y; this.g = list.get(index).g; this.h = list.get(index).h; this.f = list.get(index).f; this.parent = list.get(index).parent; } public Graph(Graph gp) { this.x = gp.x; this.y = gp.y; this.g = gp.g; this.h = gp.h; this.f = gp.f; } public Graph(Graph gp, Graph parent) { this.x = gp.x; this.y = gp.y; this.g = gp.g; this.h = gp.h; this.f = g + h; this.parent = parent; } public List<Graph> getNeighbors() { List<Graph> aux = new ArrayList<Graph>(); aux.add(new Graph(x+1, y, g,h)); aux.add(new Graph(x-1, y, g,h)); aux.add(new Graph(x, y+1, g,h)); aux.add(new Graph(x, y-1, g,h)); return aux; } public void setParent(Graph g) { parent = g; } } Little Edit: Using the System.out and the Debugger I discovered that the program ALWAYS is check the same "current" graph, (15,8) which is the (u.xMap, u.yMap) position. Looks like it keeps forever in the first step.

• Preventing threads from writing to the same file

  - by EpsilonVector

  I'm implementing an FTP-like protocol in Linux kernel 2.4 (homework), and I was under the impression that if a file is open for writing any subsequent attempt to open it by another thread should fail, until I actually tried it and discovered it goes through. How do I prevent this from happening? PS: I'm using open() to open the file.

• Is there a [Go to file...] in Xcode?

  - by Mike

  In every modern day IDE and text editor, there is an action to open a file without putting your hand on the mouse. For example: Eclipse: Cmd|Ctrl+Shift+R - Open Resource IntellIJ: Cmd|Ctrl+Shift+N - Open File TextMate: Cmd+T - Go to File In Xcode, I have found no such options. Please, please tell me I just overlooked it in my growing frustration. Is there a "Go to file" or "Open File" shortcut in Xcode?

  Hello, I am just wondering would it be better to do this: if((fd = open(filename, O_RDWR)) == -1) { fprintf(stderr, "open [ %s ]\n", strerror(errno)); return 1; } or this fd = open(filename, O_RDWR); if(fd == -1) { fprintf(stderr, "open [ %s ]\n", strerror(errno)); return 1; } Many thanks for any suggestions,

• SQL Server 2008 - "Enhanced read-ahead and scan"?

  - by Chris J

  Hi all, Can anyone point me to, or does anyone know what this "feature" of SQL Server is? Googling for it (also for "Super scan" which seems to be a synonym for the feature) reveals no information other than all the edition comparison pages that exist out there for SQL Server. I'm also not sure whether this is a stackoverflow or a serverfault question. I'll try here on serverfault first, but if folk think stackoverflow may be a better forum, drop me a comment to that effect - ta :-)

• Secret, unlogged, transparent, case-sensitive proxy in IIS6?

  - by Ian Boyd

  Does IIS have a secret, unlogged, transparent, case-sensitive proxy built into it? A file exists on the web-server: GET http://www.stackoverflow.com/javascript/ModifyQuoteArea.js HTTP/1.1 Accept: text/html, application/xhtml+xml, */* Accept-Language: en-US User-Agent: Mozilla/5.0 (compatible; MSIE 9.0; Windows NT 6.1; WOW64; Trident/5.0) Accept-Encoding: gzip, deflate Connection: Keep-Alive Host: www.stackoverflow.com HTTP/1.1 200 OK Connection: Keep-Alive Content-Length: 29246 Date: Mon, 07 Mar 2011 14:20:07 GMT Content-Type: application/x-javascript ETag: "5a0a6178edacb1:1c51" Server: Microsoft-IIS/6.0 Last-Modified: Fri, 02 Tue 2010 17:03:32 GMT Accept-Ranges: bytes X-Powered-By: ASP.NET ... Problem is that a changes made to the file will not get served, the old (i.e. February of last year) version keeps getting served: HTTP/1.1 200 OK Connection: Keep-Alive Content-Length: 29246 Date: Mon, 07 Mar 2011 14:23:07 GMT Content-Type: application/x-javascript ETag: "5a0a6178edacb1:1c51" Server: Microsoft-IIS/6.0 Last-Modified: Fri, 02 Tue 2010 17:03:32 GMT Accept-Ranges: bytes X-Powered-By: ASP.NET ... The same old file gets served, even though we've: renamed the file deleted the file restarted IIS The request for this file does not appear in the IIS logs (e.g. C:\WINNT\System32\LogFiles\W3SVC7\) And this only happens from the outside (i.e. the internet). If you issue the request locally on the server, then you will: - get the current file (file there) - 404 (file renamed) - 404 (file deleted) But if i change the case of the requested resource, i.e.: GET http://www.stackoverflow.com/javascript/MoDiFyQuOtEArEa.js HTTP/1.1 Accept: text/html, application/xhtml+xml, */* Accept-Language: en-US User-Agent: Mozilla/5.0 (compatible; MSIE 9.0; Windows NT 6.1; WOW64; Trident/5.0) Accept-Encoding: gzip, deflate Connection: Keep-Alive Host: www.stackoverflow.com Note: MoDiFyQuOtEArEa.js verses ModifyQuoteArea.js Then i do get the proper file (or get the 404 as i expect if the file is renamed or deleted). But any subsequent changes to the file will not show up until i change the case of the file i'm asking for. Checking the IIS logs all indicate that the (internet) requests are all coming the correct client on the internet (i.e. not from some intermediate proxy). Since the file doesn't exist on the hard drive anymore, i conclude that there is a proxy. The requests serviced from this proxy are not logged in the IIS logs. The requests for new files are logged, and from the client IP, not a proxy IP. The proxy is case sensitivie. This does not sound like something Microsoft, or IIS, would do: - a transparent proxy - case-sensitivie - unlogged - surviving restarts of IIS - surviving in a cache for hours i can't believe that our customer's IIS is doing these things. i'm assuming there is some other transparent proxy in front of IIS. Or, does IIS have a transparent, unlogged, case-sensitive, memory based, proxy, that caches content for at least 7 hours? (Come Monday morning, IIS is serving the correct file, unlogged).

• sshfs too slow while remote editing on Eclipse and other IDEs, what options to use to make it faster. *Not* for mac users

  - by Fullmooninu

  I've been looking into this problem, and it is common. But since there is a package for Mac with the same name, the solution for Mac users is hiding the solution for Linux users and our default sshfs. This the best I got so far, from what actually works on Linux. sshfs user@host:remoteDir localDir -o Ciphers=arcfour -oauto_cache,reconnect,no_readahead note: this question was not appropriate for stackoverflow, dunno why: http://stackoverflow.com/questions/25365487/sshfs-too-slow-what-options-to-use-to-make-it-faster-not-for-mac-users

• Install apache modules on MAMP

  - by camupod

  How can I install X-Sendfile apache module so that MAMP can use it? I have followed these instructions to install X-Sendfile, but it didn't work (it seems like it just installed it for the default apache installation). I also tried to manually copy /usr/libexec/apache2/mod_xsendfile.so to /Applications/MAMP/Library/modules/, but that produced the following error when restarting Apache: Cannot load /Applications/MAMP/Library/modules/mod_xsendfile.so into server: cannot create object file image or add library Update: The question was answered on stackoverflow: http://stackoverflow.com/questions/9101566/install-apache-module-x-sendfile-on-mamp

  When I go to the start menu I can load program icons but if I click on Documents, My Pictures, My Computer, Default Programs...all the options on the right part--I get "System call failed". How do I solve ths? Is my HD failing? Also, I don't know if it's connected but yesterday my uTorrent stopped working in a way it has never done before. I'm not able to download torrent files. In the program I get "socket unreacheable..." Also, for the last 2 days my internet has been super-slow. I checked Kaspersky for viruses. It says: "No active threats". Windows 7 64-bit.

• Scrape HTML tables from a given URL into CSV

  - by dreeves

  I seek a tool that can be run on the command line like so: tablescrape 'http://someURL.foo.com' [n] If n is not specified and there's more than one HTML table on the page, it should summarize them (header row, total number of rows) in a numbered list. If n is specified or if there's only one table, it should parse the table and spit it to stdout as CSV or TSV. Potential additional features: To be really fancy you could parse a table within a table, but for my purposes -- fetching data from wikipedia pages and the like -- that's overkill. The Perl module HTML::TableExtract can do this and may be good place to start for writing the tool I have in mind. An option to asciify any unicode. An option to apply an arbitrary regex substitution for fixing weirdnesses in the parsed table. Related questions: http://stackoverflow.com/questions/259091/how-can-i-scrape-an-html-table-to-csv http://stackoverflow.com/questions/1403087/how-can-i-convert-an-html-table-to-csv http://stackoverflow.com/questions/2861/options-for-html-scraping

• XCode Syntax Coloring Broken

  - by sw12345

  XCode frequently seems to lose it's mind, and doesn't color code system classes or provide correct "code sense" suggestions. This is endlessly frustrating. The question has been asked on at least three other occasions: http://stackoverflow.com/questions/2263994/problems-with-xcode-syntax-highlighting http://stackoverflow.com/questions/1627033/xcode-code-sense-color-completion-not-working http://stackoverflow.com/questions/2138047/xcode-code-loses-syntax-coloring I have switched by project version to/from 3.1-compatiable and 3.2-compatiable, completely restarting XCode before and after each change with no effect. I have rebuilt the code sense indexes and completely restarted XCode with no change. I have built my project to make sure there are no errors and restarted. I have copied my files (sans .svn files) to a different location - same problem. I've already completely disabled the argument "placeholders" because they screw up my documents when i type too fast... all I'm asking for is for the "esc" key to display the correct list of properties and methods.

• C# - Do you use "var"?

  C# 3.0 introduces implicitly typed variables, aka the "var" keyword. var daysInAWeek = 7; var paul = FindPerson("Paul"); var result = null as IPerson; Others have asked about what it does or what the problems with it are: http://stackoverflow.com/questions/527685/anonymous-types-vs-local-variables-when-should-one-be-used http://stackoverflow.com/questions/209199/whats-the-point-of-the-var-keyword http://stackoverflow.com/questions/41479/use-of-var-keyword-in-c I am interested in some numbers - do you use it? If so, how do you use it? I never use var (and I never use anonymous types) I only use var for anonymous types I only use var where the type is obvious I use var all the time!

• LINQ to SQL or Entities, at this point?

  - by orlon

  I'm a bit late to the game and have decided to spend some spare time learning LINQ. As an exercise, I'm going to rewrite a WebForms app in MVC 2 (which is also new to me). I managed to find a few topics regarding LINQ here (http://stackoverflow.com/questions/16322/learning-about-linq, http://stackoverflow.com/questions/8050/beginners-guide-to-linq, http://stackoverflow.com/questions/252683/is-linq-to-sql-doa), which brought the concern of Entities vs SQL to my attention. The threads are all over a year old however, and I can't seem to find any definitive information on which ORM is preferable. Is Entities more or less LINQ to SQL 2.0 at this point? Is it still more difficult to use? Is there any reason to use LINQ to SQL, or should I just jump into Entities? The applications I write at my present employer have a lengthy lifecycle (~10 years), so I'm trying to pick the best technology available.

• illegal charcters in facebook graph api

  - by user1465888

  i was trying to get how many facebook likes an url got, through facebook graph api. to get the likes i need to get the content from this url: http://graph.facebook.com/?id=URL for example, try to get into this url: "graph.facebook.com/?id=http://stackoverflow.com" you will see how many "shares" the url got. shares is the sum of shares and likes, so every thing was working good when i was trying to this. the problem start when i use special charcters. when i using the "?" charcter everything work okey. but when i use "&" charcter the url cuts itself. try this: "graph.facebook.com/?id=http://stackoverflow.com?p=blabla&a=fsdf" you can see in this page that the id actullay cut itself when it get to the "&" charcter and the page ends like this: { "id": "http://stackoverflow.com?p=blabla" } sorry for my bad english...

• RSS feed per tag

  - by niaher

  Hi. Suppose stackoverflow.com wanted to have an RSS feed per each tag. They would probably have requests like stackoverflow.com/rss?tag=aspnet to return appropriate RSS feeds. This is the easy part. Now when the user requested stackoverflow.com/rss?tag=aspnet he would see some XML. Instead it would be better to show a page where user can choose which RSS reader he wants to subscribe with (just like feedburner.com). My question is: is there any ready-made code (html+javascript) that I can copy-paste to create such a subscription page? Basically I want to copy feedburner.com's subscription page onto my own site. PS - I would be happy using feedburner.com, but it would require me to create a feed for each tag manually, which is impractical.
