• Perf: Viewing thousands of images in Silverlight 3 on a 3D Wall

  - by Bob Holland

  I currently work on a very cool Silverlight app that displays photos in a 3D wall space like the Wall3D demo that is thrown in with Blend 3. The problem I am currently facing is performance. The app works like this: As you scroll right or left the 3d photo wall rotates As each movement is made, the next column of photos are downloaded, decoded into a BitmapImage and thrown into a 3D Wall Node. As you can imagine users (if you let them) will want to flip through the photos really quickly, but the problem I have is I cannot display the photos quick enough. In most cases it's a beautiful app that works really well, but when an album contains over 300 photos, you can imagine the sort of memory taken up by all the BitmapImage classes and how moving the slider can jump from photo 20 to photo 120 in a second. Of course we have algorithms in place to not download every photo in between, but I still can't work out a fast way to get the photos displayed. It may be a case that we need to throw away the 'great for show' 3D wall and go to a flat DeepZoom like wall like the Playboy archive one that Vertigo did. Still not sure, let me know your thoughts. P.S. We are using Kit3D for all the 3D work, it's using PerspectiveCamera, Model3DGroup, ModelVisual3D, RotateTransform3D & TranslateTransform3D. Cheers, Bob.

• Dealing with "Coder's Block" (or blank form syndrome)

  - by robsoft

  I know this is the sort of somewhat open-ended question that we're discouraged from asking, but there are lots of open-ended questions around already, and this is something quite relevant to me right now. Do you ever get those times when you're about to start work on a new function/feature of an established system, and you get "coder's block"?. It's like a mental freeze at the sight of a large, completely unpopulated dialog, or an empty code file with just the stub reference headers etc. Do you ever have that 'ulp' moment that seems to sap all your momentum and leave you wide open to distractions (surfing the web for inspiration, checking out 'crackoverflow' etc)? Not that I'd wish it on anyone, but hopefully some of you do, and hopefully some of you can suggest tips or strategies for overcoming the situation, regaining your momentum and becoming productive again. I usually try to reduce what I'm about to do down to absurdly small steps, in the hope that as the job becomes just a series of 'doh' tasks, I'll kickstart myself into working through them. However sometimes, particularly when a deadline is looming, I'll get overwhelmed by this approach as I realise I probably don't have enough time to do all of those tiny steps properly. Those are the darkest moments, (often literally) just before dawn! This situation can be particularly crippling if you mostly work alone, too. Any thoughts or suggestions? Any methods that you found helpful yourself?

• Logic inside an enum

  - by Vivin Paliath

  My colleagues and I were having a discussion regarding logic in enums. My personal preference is to not have any sort of logic in Java enums (although Java provides the ability to do that). The discussion in this cased centered around having a convenience method inside the enum that returned a map: public enum PackageTypes { Letter("01", "Letter"), .. .. Tube("02", "Packaging Tube"); private String packageCode; private String packageDescription; .. .. public static Map<String, String> toMap() { Map<String, String> map = new LinkedHashMap<String, String>(); for(PackageType packageType : PackageType.values()) { map.put(packageType.getPackageCode(), packageType.getPackageDescription()); } return map; } } My personal preference is to pull this out into a service. The argument for having the method inside the enum centered around convenience. The idea was that you don't have to go to a service to get it, but can query the enum directly. My argument centered around separation of concern and abstracting any kind of logic out to a service. I didn't think "convenience" was a strong argument to put this method inside an enum. From a best-practices perspective, which one is better? Or does it simply come down to a matter of personal preference and code style?

• Scaling gwt's "Contacts" (sample project) AppController with MVP

  - by brad

  I'm just learning GWT so I'm still trying to sort out all of its quirks and features. I'm reading through the example they give illustrating the MVP pattern, and I pretty much get it, except I'm wondering about one thing. The AppController they use implements the ValueChangeHandler interface and the onValueChange method is triggered when history changes. My problem is with this onValueChange in the AppController (i've included it below for anyone who hasn't seen the sample project). It's doing a string comparison on the history token sent in and instantiating the appropriate presenter to handle the action. This is all fine and dandy for the sample app with 3 actions, but how would one scale this to a real app with many more actions? Sticking to this pattern would lead to a pretty large/ugly else if, but I'm still too new to GWT (and java) to infer a better pattern for larger apps. Any help is greatly appreciated! public class AppController implements Presenter, ValueChangeHandler<String> { ... public void onValueChange(ValueChangeEvent<String> event) { String token = event.getValue(); if (token != null) { Presenter presenter = null; if (token.equals("list")) { presenter = new ContactsPresenter(rpcService, eventBus, new ContactsView()); } else if (token.equals("add")) { presenter = new EditContactPresenter(rpcService, eventBus, new EditContactView()); } else if (token.equals("edit")) { presenter = new EditContactPresenter(rpcService, eventBus, new EditContactView()); } if (presenter != null) { presenter.go(container); } } } }

• How to program a neural network for chess?

  - by marco92w

  Hello! I want to program a chess engine which learns to make good moves and win against other players. I've already coded a representation of the chess board and a function which outputs all possible moves. So I only need an evaluation function which says how good a given situation of the board is. Therefore, I would like to use an artificial neural network which should then evaluate a given position. The output should be a numerical value. The higher the value is, the better is the position for the white player. My approach is to build a network of 385 neurons: There are six unique chess pieces and 64 fields on the board. So for every field we take 6 neurons (1 for every piece). If there is a white piece, the input value is 1. If there is a black piece, the value is -1. And if there is no piece of that sort on that field, the value is 0. In addition to that there should be 1 neuron for the player to move. If it is White's turn, the input value is 1 and if it's Black's turn, the value is -1. I think that configuration of the neural network is quite good. But the main part is missing: How can I implement this neural network into a coding language (e.g. Delphi)? I think the weights for each neuron should be the same in the beginning. Depending on the result of a match, the weights should then be adjusted. But how? I think I should let 2 computer players (both using my engine) play against each other. If White wins, Black gets the feedback that its weights aren't good. So it would be great if you could help me implementing the neural network into a coding language (best would be Delphi, otherwise pseudo-code). Thanks in advance!

• What algorithms do "the big ones" use to cluster news?

  - by marco92w

  I want to cluster texts for a news website. At the moment I use this algorithm to find the related articles. But I found out that PHP's similar_text() gives very good results, too. What sort of algorithms do "the big ones", Google News, Topix, Techmeme, Wikio, Megite etc., use? Of course, you don't know exactly how the algorithms work. It's secret. But maybe someone knows approximately the way they work? The algorithm I use at the moment is very slow. It only compares two articles. So for having the relations between 5,000 articles you need about 12,500,000 comparisons. This is quite a lot. Are there alternatives to reduce the number of necessary comparisons? [I don't look for improvements for my algorithm.] What do "the big ones" do? I'm sure they don't always compare one article to another and this 12,500,000 times for 5,000 news. It would be great if somebody can say something about this topic.

• Slow Performance -- ASP .NET ASPNET_WP.EXE and CSC.EXE Running After Clicking Redirect Link

  - by Dan7el

  I click on a link from one page that does a redirect to another page (Response.Redirect(page.aspx)). The browser churns for about 30 seconds and the page displays. I'm trying to track down why it takes so long to load the page. The page hosts two other custom controls. I have commented out the lines of code for each and both controls, and the page still takes about 30 seconds to load. I've set breakpoints on the Page_Load event for each of the controls as well as page.aspx and it also takes about 30 seconds from clicking the link with the Response.Redirect to the first break point. I loaded up task manager and clicked on the link. I notice aspnet_wp.exe and csc.exe run during this 30 second time frame. I'm wondering if there are some sort of code-behind shinanigans going on while I'm waiting for the page to load. This only occurs the first time I click on the link. Afterwards, it's not as slow. I've googled but there's not a lot of useful information about this. Anyone have any ideas? Thanks, ---Dan---

• Objective-C : Sorting NSMutableArray containing NSMutableArrays

  - by Dough

  Hi ! I'm currently using NSMutableArrays in my developments to store some data taken from an HTTP Servlet. Everything is fine since now I have to sort what is in my array. This is what I do : NSMutableArray *array = [[NSMutableArray arrayWithObjects:nil] retain]; [array addObject:[NSArray arrayWithObjects: "Label 1", 1, nil]]; [array addObject:[NSArray arrayWithObjects: "Label 2", 4, nil]]; [array addObject:[NSArray arrayWithObjects: "Label 3", 2, nil]]; [array addObject:[NSArray arrayWithObjects: "Label 4", 6, nil]]; [array addObject:[NSArray arrayWithObjects: "Label 5", 0, nil]]; First column contain a Label and 2nd one is a score I want the array to be sorted descending. Is the way I am storing my data a good one ? Is there a better way to do this than using NSMutableArrays in NSMutableArray ? I'm new to iPhone dev, I've seen some code about sorting but didn't feel good with that. Thanks in advance for your answers !

• Get ListView Visible items

  - by Vincent Piel

  I have a ListView which might contains a lot of items, so it is virtualized and recycling items. It does not use sort. I need to refresh some value display, but when there are too many items, it is too slow to update everything, so I would like to refresh only the visible items. How could I get a list of all currently displayed items ? I tried to look into the ListView or in the ScrollViewer, but I still have no idea how to achieve this. The solution must NOT go through all items to test if they can be seen, because this would be too slow. I'm not sure code or xaml would be usefull, it is just a Virtualized/Recycling ListView with its ItemSource bound to an Array. Edit Answer : thanks to akjoshi, i found the way : get the ScrollViewer of the ListView (with a FindDescendant method, that you can do yourself with the VisualTreeHelper ). Then use its ScrollViewer.VerticalOffset : it is the number of the first item shown and ScrollViewer.ViewportHeight : it is the count of items shown. Rq : CanContentScroll must be true.

• Packaging for Ubuntu - Web Application

  - by Sam

  A web application has no make file unlike C++ or anything like that. However, it needs to be placed into specific directories...e.g /var/www. I'm new to linux packaging, so my question is, how do I package my app into a .deb such that when its being installed, it gets put into something like /etc/myprogram/bundles/myprogram-3.4? Mine in particular is a java app running on apache tomcat. I've managed to create a .deb file by reading painstakingly every word in http://www.debian.org/doc/manuals/maint-guide. However when I follow the instructions I end up getting 1) a .deb file that is 1.7kb instead of the ~240mb that it should be, because apparently it is lacking all my source code. 2) confused because I don't know whether I was supposed to write some sort of makefile. I am not even sure where to go about learning the answer to that question, and then I'd have to deal with how to write a makefile. I've posted a similar question to ubuntuforums, but I feel like I'm more likely to get a response here.

• WCF net.tcp bindings, message formats and security questions

  - by RemotecUk

  Hi, sorry for the stupid questions but there are just some things about WCF I cant get my head around. Would be greatful for some advice on the following.... At a very basic level is it correct that WCF uses either Binary (Net.Tcp), HTTP or MSMQ to transfer my message on the wire? However is it true that in all cases, regardless of how the data is transferred the message itself in in the SOAP format with headers and a body? So its a sort of XML message that is transmitted in either HTTP/S or in a binary format. Is Net.Tcp a good choice for my client server app - its similar to a messenger app in that the clients are all remote users on the other side of the firewall to my server. Most things I am reading are telling to use WS* and HTTP. Is Net.Tcp secured by standard and without certificates? - that is - people cannot listen on the wire and decode the data thats going to and from. Is it possible to send a username and password using net.tcp and without an installed certificate? If so I presume I can hook this up to my membership provider and authenticate access to each method on my service contract implementation. I presume that with username and password security, the proxy is initialised with the username and password and that this information is is sent with every request. Then my membership provider will be invoked for each method call and do whatever it needs to do to get the authorisation for the method. Sorry for the dump of questions but would be great to know if Im thinking the right way about how WCF works. Thanks.

• Question regarding the iPhone In App Purchase capabilities

  - by Wesley

  Hi everyone. I am working on releasing an app that will greatly benefit from using the in app purchase model. The app is a sort of book viewer, and the content I would like to make available for purchase will be more books in various languages. Each book is stored in sqlite format, in separate .db files. Now, the way that my developer has set it all up is that he added a line onto the bottom of the info.plist file called databases. Inside that database section, I can type in 'es' as the key, and for the value the name of the spanish database, and it populates in a uitableview in spanish, using NSLocale. So it is very easy to setup and implement different databases, which is great, but now I am confused about how I can implement my in app purchase model. Sorry about the long winded intro, here is my question: Is it possible to have an in app purchase add a line to my info.plist file? Or if not, is it possible to have the purchase reveal a new and updated plist file altogether that I would have already setup correctly? Any help here would be appreciated. Thanks

• Confused about C++'s std::wstring, UTF-16, UTF-8 and displaying strings in a windows GUI

  - by dfrey

  I'm working on a english only C++ program for Windows where we were told "always use std::wstring", but it seems like nobody on the team really has much of an understanding beyond that. I already read the question titled "std::wstring VS std::string. It was very helpful, but I still don't quite understand how to apply all of that information to my problem. The program I'm working on displays data in a Windows GUI. That data is persisted as XML. We often transform that XML using XSLT into HTML or XSL:FO for reporting purposes. My feeling based on what I have read is that the HTML should be encoded as UTF-8. I know very little about GUI development, but the little bit I have read indicates that the GUI stuff is all based on UTF-16 encoded strings. I'm trying to understand where this leaves me. Say we decide that all of our persisted data should be UTF-8 encoded XML. Does this mean that in order to display persisted data in a UI component, I should really be performing some sort of explicit UTF-8 to UTF-16 transcoding process? I suspect my explanation could use clarification, so I'll try to provide that if you have any questions.

• Source-to-source compiler framework wanted

  - by cheungcc_2000

  Dear all, I used to use OpenC++ (http://opencxx.sourceforge.net/opencxx/html/overview.html) to perform code generation like: Source: class MyKeyword A { public: void myMethod(inarg double x, inarg const std::vector<int>& y, outarg double& z); }; Generated: class A { public: void myMethod(const string& x, double& y); // generated method below: void _myMehtod(const string& serializedInput, string& serializedOutput) { double x; std::vector<int> y; // deserialized x and y from serializedInput double z; myMethod(x, y, z); } }; This kind of code generation directly matches the use case in the tutorial of OpenC++ (http://www.csg.is.titech.ac.jp/~chiba/opencxx/tutorial.pdf) by writing a meta-level program for handling "MyKeyword", "inarg" and "outarg" and performing the code generation. However, OpenC++ is sort of out-of-date and inactive now, and my code generator can only work on g++ 3.2 and it triggers error on parsing header files of g++ of higher version. I have looked at VivaCore, but it does not provide the infra-structure for compiling meta-level program. I'm also looking at LLVM, but I cannot find documentation that tutor me on working out my source-to-source compilation usage. I'm also aware of the ROSE compiler framework, but I'm not sure whether it suits my usage, and whether its proprietary C++ front-end binary can be used in a commercial product, and whether a Windows version is available. Any comments and pointers to specific tutorial/paper/documentation are much appreciated.

• What's the recommended implemenation for hashing OLE Variants?

  - by Barry Kelly

  OLE Variants, as used by older versions of Visual Basic and pervasively in COM Automation, can store lots of different types: basic types like integers and floats, more complicated types like strings and arrays, and all the way up to IDispatch implementations and pointers in the form of ByRef variants. Variants are also weakly typed: they convert the value to another type without warning depending on which operator you apply and what the current types are of the values passed to the operator. For example, comparing two variants, one containing the integer 1 and another containing the string "1", for equality will return True. So assuming that I'm working with variants at the underlying data level (e.g. VARIANT in C++ or TVarData in Delphi - i.e. the big union of different possible values), how should I hash variants consistently so that they obey the right rules? Rules: Variants that hash unequally should compare as unequal, both in sorting and direct equality Variants that compare as equal for both sorting and direct equality should hash as equal It's OK if I have to use different sorting and direct comparison rules in order to make the hashing fit. The way I'm currently working is I'm normalizing the variants to strings (if they fit), and treating them as strings, otherwise I'm working with the variant data as if it was an opaque blob, and hashing and comparing its raw bytes. That has some limitations, of course: numbers 1..10 sort as [1, 10, 2, ... 9] etc. This is mildly annoying, but it is consistent and it is very little work. However, I do wonder if there is an accepted practice for this problem.

• Roadmap to Android development

  - by Matthew

  Hello, I've done a little research, and am interested in developing for Android. I've never programmed before, and have no idea how to go from zero experience to developing for a mobile device. My interest is in eventually making some sort of 2d game. Is there a lesson plan for starting from the ground up? I would think one would need to learn the Java language to start. Looking at the Sun website, it's a bit daunting. Is there a book, specifically, that would wrap up this knowledge in a bit of a directed lesson plan? I'm not sure if opengl-es is what would be required for 2d games. I've done a little research on this, and it's even far more daunting than Java itself. I can't even begin to figure out where to start with even just opengl, sans -es. My best guess would be that I need further knowledge in Java to continue with this, but even still, is it possible to learn concurrently with Java?

• YUI DataTable with JSON and client side filtering Data Error

  Hi, I don't understand what I'm doing wrong here ! I keep getting a Data Error. But I validated the JSON and it's ok... Here is the javascript from the YUI Datatble example (slightly modified). <div class="markup"> <label for="filter">Filter by state:</label> <input type="text" id="filter" value=""> <div id="tbl"></div> -- YAHOO.util.Event.addListener(window, "load", function() { //var Ex = YAHOO.namespace('example'); var dataSource = new YAHOO.util.DataSource("jsondb/json_meta_proxy.html",{ responseType : YAHOO.util.DataSource.TYPE_JSON, responseSchema : { resultsList: "records", fields: [ {key:"idprojet"}, {key:"nomprojet"} ], metaFields: { totalRecords: "totalRecords" } }, doBeforeCallback : function (req,raw,res,cb) { // This is the filter function var data = res.results || [], filtered = [], i,l; if (req) { req = req.toLowerCase(); for (i = 0, l = data.length; i and here is the JSON data in the file "jsondb/json_meta_proxy.html" { "recordsReturned": 1, "totalRecords": 1, "startIndex": 0, "sort": "idprojet", "dir": "asc", "records": [ { "idprojet": "11256", "nomprojet": "" } ] } Many thanks for your help !!!

• Setting httponly in JSESSIONID cookie (Java EE 5)

  - by mythandros

  I'm trying to set the httponly flag on the JSESSIONID cookie. I'm working in Java EE 5, however, and can't use setHttpOnly(). First I tried to create my own JSESSIONID cookie from within the servlet's doPost() by using response.setHeader(). When that didn't work, I tried response.addHeader(). That didn't work either. Then, I learned that the servlet handled converting the session into a JSESSIONID cookie and inserting it into the http header so if I want to play with that cookie, I'll have to write a filter. I wrote a filter and played with setHeader()/addHeader() there, again to no avail. Then, I learned that there's some flush/close action going on in the response object before it gets to the filter so if I want to manipulate the data, I need to extend HttpServletResponseWrapper and pass that to filterChain.doFilter(). This is done but I'm still not getting results. Clearly I'm doing something wrong but I don't know what. I'm not sure if this is at all relevant to the question at hand but no html document is being returned by the servlet to the browser. All that's really happening is that some objects are being populated and returned to a JSP document. I've sort of assumed that The Session object is turned into a JSESSIONID cookie and wrapped -- along with the objects added to the request -- in an http header before being sent to the browser. I'd be happy to post some code but I want to rule out the possibility that my difficulties stem from a misunderstanding of the theory first.

• Error while dynamically loading mapi32.dll

  - by The_Fox

  Our application uses Simple MAPI to send e-mails. One of our clients has problems sending e-mail from a session on his terminal server. The mapi32.dll is loaded with a call to LoadLibrary which succeeds, but then our application tries to get the addresses of the functions MAPILogon, MAPILogOff, MAPISendMail, MAPIFreeBuffer and MAPIResolveName. The problem is that GetProcAddress fails for those functions with an ERROR_ACCESS_DENIED (code: 5) except for MAPIFreeBuffer. It looks like some sort of security thing. How can I fix this or should I use another method to send mail?

• When to use custom exceptions vs. existing exceptions vs. generic exceptions

  - by Ryan Elkins

  I'm trying to figure out what the correct form of exceptions to throw would be for a library I am writing. One example of what I need to handle is logging a user in to a station. They do this by scanning a badge. Possible things that could go wrong include: Their badge is deactivated They don't have permission to work at this station The badge scanned does not exist in the system They are already logged in to another station elsewhere The database is down Internal DB error (happens sometimes if the badge didn't get set up correctly) An application using this library will have to handle these exceptions one way or another. It's possible they may decide to just say "Error" or they may want to give the user more useful information. What's the best practice in this situation? Create a custom exception for each possibility? Use existing exceptions? Use Exception and pass in the reason (throw new Exception("Badge is deactivated.");)? I'm thinking it's some sort of mix of the first two, using existing exceptions where applicable, and creating new ones where needed (and grouping exceptions where it makes sense).

• Manual drag-drop operations in Flex

  - by Yarin

  This is a two-part problem: A) I'm implementing several irregular drag-drop operations in Flex (e.g. DataGrid ItemRenderer into Tree). My preference was modifying DragManager operations to meet my needs, and in fact using DragManager allows me to do everything I need, but I'm having serious issues with performance. For example, dragging anything over a many-columned DataGrid, whether the drag was initiated with DragManager.doDrag, or just using native ListBase drag-drop functionality, slows the drag movement to a crawl. Even if the DataGrid is disabled/ not listenening for any move/drag events, this happens. On the other hand, if the drag is initiated by calling .startDrag() on the Sprite, the drag is smooth and performs great over DataGrids and everything else. So part A would be: Is there a reason why .startDrag() operations work so well, while drags initiated through DragManager.doDrag suffer so badly when over certain components? B) If indeed the solution is to handle drag-drops using .startDrag(), how would I go about determining what component the mouse is over when the drag is released? In my example, my dragged object is brought up to the top level of the display list, and so is being moved around in stage coordinates. mouseMove, mouseOver events don't fire on the components I'm dragging over because the mouse is constantly over the dragged component, so I would need some sort of stage.coordinate - visibleComponentAtThatCoordinate conversion. Any thoughts on this? Thanks alot!-- Yarin

• XML Catalog file failing to resolve

  - by newt

  I'm using an OASIS v 1.1 compatible resolver (Norm Walsh's XMLResolver in conjunction with the catalog below. However, I'm pretty sure I've made some sort of obvious error here (this is the first time I've needed to use v 1.1 features) since attempting to resolve OxChapML.dtd fails. Can anyone see something obviously wrong with this? Or even subtly wrong? <?xml version="1.0" encoding="UTF-8"?> <!DOCTYPE catalog PUBLIC "-//OASIS//DTD XML Catalogs V1.1//EN" "http://www.oasis-open.org/committees/entity/release/1.1/catalog.dtd"> <catalog xmlns="urn:oasis:names:tc:entity:xmlns:xml:catalog"> <group xml:base="file:///Volumes/Ac-EDP/DTG/SP%20DTD%20management/OUP_DTD/"> <public publicId="-//OXFORD//DTD OXCHAPML//EN" uri="OxChapML.dtd"/> <public publicId="-//OXFORD//DTD OXENCYCLML//EN" uri="xEncyclML.dtd"/> <public publicId="-//OXFORD//DTD OXLAWML//EN" uri="OxLawML.dtd"/> <public publicId="-//OXFORD//DTD OXSTRUCTML//EN" uri="OxStructML.dtd"/> <public publicId="-//OXFORD//DTD OXLAWREPML//EN" uri="OxLawRepML.dtd"/> <public publicId="-//OXFORD//DTD OXBILINGML//EN" uri="OxBilingML.dtd"/> <public publicId="-//OXFORD//DTD OXMONOLINGML//EN" uri="OxMonolingML.dtd"/> <public publicId="-//OXFORD//DTD TIMELINES//EN" uri="timelines.dtd"/> <systemSuffix OxChapML.dtd" systemIdSuffix="OxChapML.dtd"/> <systemSuffix uri="xEncyclML.dtd" systemIdSuffix="xEncyclML.dtd"/> <systemSuffix systemIdSuffix="OxLawML.dtd" uri="OxLawML.dtd"/> <systemSuffix systemIdSuffix="OxStructML.dtd" uri="OxStructML.dtd"/> <systemSuffix systemIdSuffix="OxLawRepML.dtd" uri="OxLawRepML.dtd"/> <systemSuffix systemIdSuffix="OxBilingML.dtd" uri="OxBilingML.dtd"/> <systemSuffix systemIdSuffix="OxMonolingML.dtd" uri="OxMonolingML.dtd"/> <systemSuffix systemIdSuffix="timelines.dtd" uri="timelines.dtd"/> </group> </catalog>

• Emacs recursive project search

  - by hekevintran

  I am switching to Emacs from TextMate. One feature of TextMate that I would really like to have in Emacs is the "Find in Project" search box that uses fuzzy matching. Emacs sort of has this with ido, but ido does not search recursively through child directories. It searches only within one directory. Is there a way to give ido a root directory and to search everything under it? Update: The questions below pertain to find-file-in-project.el from Michal Marczyk's answer. If anything in this message sounds obvious it's because I have used Emacs for less than one week. :-) As I understand it, project-local-variables lets me define things in a .emacs-project file that I keep in my project root. How do I point find-file-in-project to my project root? I am not familiar with regex syntax in Emacs Lisp. The default value for ffip-regexp is: ".*\\.\\(rb\\|js\\|css\\|yml\\|yaml\\|rhtml\\|erb\\|html\\|el\\)" I presume that I can just switch the extensions to the ones appropriate for my project. Could you explain the ffip-find-options? From the file: (defvar ffip-find-options "" "Extra options to pass to `find' when using find-file-in-project. Use this to exclude portions of your project: \"-not -regex \\".vendor.\\"\"") What does this mean exactly and how do I use it to exclude files/directories? Could you share an example .emacs-project file?

• Powershell: Select-Object with additional calculated difference value

  - by David.Chu.ca

  Let me explain my question. I have a daily report about one PC's free space as in text file (sp.txt) like: DateTime FreeSpace(MB) ----- ------------- 03/01/2010 100.43 DateTime FreeSpace(MB) ----- ------------- 03/02/2010 98.31 .... Then I need to use this file as input to generate a report with difference of free space between dates: DateTime FreeSpace(MB) Change ----- ------------- ------ 03/01/2010 100.43 03/02/2010 98.31 2.12 .... Here are some codes I have to get above result without the additional "Change" calculation: Get-Content "C:\report\sp.txt" ` | where {$_.trim().length -gt 0 -and -not ($_ -like "Date*") -and -not ($_ -like "---*")} ` | Select-Object @{Name='DateTime'; expression={[DateTime]::Parse($_.SubString(0, 10).Trim())}}, ` @{Name='FreeSpace(MB)'; expression={$_.SubString(12, 12).Trim()}}, ` | Sort-Object DateTime ` | Select-Object DateTime, 'FreeSpace(MB)' |ft -AutoSize # how to add additional column Change to this Select-Object? My understanding is that Select-Object will return a collection of objects. Here I create this collection from an input text file(parse each line into parts: datetime and freespace(MB)). In order to calculate the difference between dates, I guess that I need to add additional calculated value to the result of the last Select-Object, or pipe the result to another Select-Object with the calculation as additional property or column. In order to do it, I need to get the previous row's FreeSpace value. Not sure if it is possible and how?
