• Some Early Considerations

  - by Chris Massey

  Following on from my previous post, I want to say "thank you" to everyone who has got in touch and got involved – you are pioneers! An update on where we are right now: paper prototypes v1 To be more specific, we’ve picked two of the ideas that seem to have more pros than cons, turned them into Balsamiq mockups, and are getting them fleshed out with realistic content. We’ll initially make these available to the aforementioned pioneers (thank you again), roll in the feedback, and then open up to get more data on what works and what doesn’t. If you’ve got any questions about this (or what we’re working on right now), feel free to ask me in the comments below. I’ve had a few people express an interest in the process we’re going through, and I’m more than happy to share details more frequently as we go along – not least because you, dear reader, will help us stay on target and create something Good. To start with, here’s a quick flashback to bring you all up to speed. A Brief Retrospective As you may already know, we’re creating a new publishing asset specifically focused on providing great content for web developers. We don’t yet know exactly what this thing will look like, or exactly how it will work, but we know we want to create something that is useful different. For my part, I’m seriously excited at the prospect of building a genuinely digital publishing system (as opposed to what most publishing is these days, which is print-style publishing which just happens to be on the web). The main challenge at this point is working out our build-measure-assess loop to speed up our experimental turn-around, and that’ll get better as we run more trials. Of course, there are a few things we’ve been pondering at this early conceptual stage: Do we publishing about heterogeneous technology stacks from day 1, or do we start with ASP.NET (which we’re familiar with) & branch out later? There are challenges with either approach. What publishing "modes" are already being well-handled? For example, the likes of Pluralsight, TekPub, and Treehouse have pretty much nailed video training (debate about price, if you like), and unless we think we can do it faster / better / cheaper (unlikely, for the record), we should leave them to it. Where should we base whatever we create? Should we create a completely new asset under a new name, graft something onto Simple-Talk (like the labs), or just build something directly into Simple-Talk? It sounds trivial, but it does have at least some impact on infrastructure and what how we manage the different types of content we (will) have. Are there any obvious problems or niches that we think could address really well, or should we just throw ideas out and see what readers respond to? What kind of users do we want to provide for? This actually deserves a little bit of unpacking… Why are you here? We currently divide readers into (broadly) the categories: Category 1: I know nothing about X, and I’d like to learn about it. Category 2: I know something about X, but I’d like to learn how to do something specific with it. Category 3: Ah man, I have a problem with X, and I need to fix it now. Now that I think about it, I might also include a 4th class of reader: Category 4: I’m looking for something interesting to engage my brain. These are clearly task-based categorizations, and depending on which task you’re performing when you arrive here, you’re going to need different types of content, or will have specific discovery needs. One of the questions that’s at the back of my mind whenever I consider a new idea is “How many of the categories will this satisfy?” As an example, typical video training is very well suited to categories 1, 2, and 4. StackOverflow is very well suited to category 3, and serves as a sign-posting system to the rest. Clearly it’s not necessary to satisfy every category need to be useful and popular, but being aware of what behavior readers might be exhibiting when they arrive will help us tune our ideas appropriately. < / Flashback > We don’t have clean answers to most of these considerations – they’re things we’re aware of, and each idea we look at is going to be best suited to a different mix of the options I’ve described. Our first experimental loop will be coming full circle in the next few days, so we should start to see how the different possibilities vary between ideas. Free to chime in with questions and suggestions about anything I’ve just brain-dumped, or at any stage as we go along. If you see anything that intrigued or enrages you, or just have an idea you’d like to share, I’d love to hear from you.

• YouTube SEO: Video Optimization

  - by Mike Stiles

  SEO optimization is still regarded as one of the primary tools in the digital marketing kit. However and wherever a potential customer is conducting a search, brands want their content to surface in the top results. Makes sense. But without a regular flow of good, relevant content, your SEO opportunities run shallow. We know from several studies video is one of the most engaging forms of content, so why not make sure that in addition to being cool, your videos are helping you win the SEO game? Keywords:-Decide what search phrases make the most sense for your video. Don’t dare use phrases that have nothing to do with the content. You’ll make people mad.-Research those keywords to see how competitive they are. Adjust them so there are still lots of people searching for it, but there are not as many links showing up for it.-Search your potential keywords and phrases to see what comes up. It’s amazing how many people forget to do that. Video Title: -Try to start and/or end with your keyword.-When you search on YouTube, visual action words tend to come up as suggested searches. So try to use action words. Video Description: -Lead with a link to your site (include http://). -Don’t stuff this with your keyword. It leads to bad writing and it won’t work anyway. This is where you convince people to watch, so write for humans. Use some showmanship. -At the end, do a call to action (subscribe, see the whole playlist, visit our social channels, etc.) Video Tags:-Don’t over-tag. 5-10 tags per video is plenty. -If you’re compelled to have more than 10, that means you should probably make more videos specifically targeting all those keywords. Find Linking Pals:-45% of videos are discovered on video sites. But 44% are found through links on blogs and sites.-Write a blog about your video’s content, then link to the video in it. -A good site for finding places to guest blog is myblogguest.com-Once you find good linking partners, they’ll link to your future videos (as long as they’re good and you’re returning the favor). Tap the Power of Similar Videos:-Use Video Reply to associate your video with other topic-related videos. That’s when you make a video responding to or referencing a video made by someone else. Content:-Again, build up a portfolio of videos, not just one that goes after 30 keywords.-Create shorter, sequential videos that pull them deeper into the content and closer to a desired final action.-Organize your video topics separately using Playlists. Playlists show up as a whole in search results like individual videos, so optimize playlists the same as you would for a video. Meta Data:-Too much importance is placed on it. It accounts for only 15% of search success.-YouTube reads Captions or Transcripts to determine what a video is about. If you’re not using them, you’re missing out.-You get the SEO benefit of captions and transcripts whether the viewers has them toggled on or not. Promotion:-This accounts for 25% of search success.-Promote the daylights out of your videos using your social channels and digital assets. Don’t assume it’s going to magically get discovered. -You can pay to promote your video. This could surface it on the YouTube home page, YouTube search results, YouTube related videos, and across the Google content network. Community:-Accounts for 10% of search success.-Make sure your YouTube home page is a fun place to spend time. Carefully pick your featured video, and make sure your Playlists are featured. -Participate in discussions so users will see you’re present. The volume of ratings/comments is as important as the number of views when it comes to where you surface on search. Video Sitemaps:-As with a web site, a video sitemap helps Google quickly index your video.-Google wants to know title, description, play page URL, the URL of the thumbnail image you want, and raw video file location.-Sitemaps are xml files you host or dynamically generate on your site. Once you’ve made your sitemap, sign in and submit it using Google webmaster tools. Just as with the broadcast and cable TV channels, putting a video out there is only step one. You also have to make sure everybody knows it’s there so the largest audience possible can see it. Here’s hoping you get great ratings. @mikestiles

• Flat File Connection Manager in SSIS package shows "Valid File Name Must be Selected"

  - by Traples

  (Flat File Location) Samba Share | Windows Share (SSIS) _______________________________ | | XP 32bit | Works | Works | | 2003 Serv 32bit | Works | Works | | Vista 64bit | ERROR | Works | | Win 7 64bit | ERROR | Works | | 2008 Serv 64bit | ERROR | Works I created an SSIS package in VS 2008 that parses a flat file from a shared folder and puts the records into a SQL Server db. I recently installed Windows 7 and VS 2008 on a new workstation. When I import the package from TFS and open it, I get the error Validation error. Parse and Import Catalog Flat File: MySSISPackage: The file name "\\shared\flatfile.txt" specified in the connection was not valid. When I open the Flat File Connection Manager Editor, there is an error stating: A valid file name must be selected I can browse to and select the file from inside the editor, but I cannot change any properties, or move away from the General tab because of this error. If I go back to my laptop (Windows XP), where the package was first created, there is no error. Both workstations are on the same domain, and I'm logging in using the same credentials. Any ideas as to why I would receive this error from one workstation and not another? UPDATE: If I take the .dtsx package from the running workstation and load it into SSIS on the server, I get the following errors when it tries to run: Error: The file name "\\shared\flatfile.txt" specified in the connection was not valid. and... Error: Connection "MySSISPackage" failed validation. and... Error: The file name property is not valid. The file name is a device or contains invalid characters. UPDATE 2: a) The Shared folder I'm trying to pull the flat file from is a Samba share on a Unix box. b) If I access the file using SSIS on any 64-bit platform (Windows 7 64-bit, Vista 64-bit, Windows Server 2008) I get the error "A valid file name must be selected." c) Accessing the file using SSIS from 32-bit environments (Windows XP 32-bit, Windows Server 2003 32-bit) there is no problem. d) If I move the file to a shared folder on a Windows server, 64-bit SSIS recognizes the file.

• Computer science undergraduate project ideas

  - by Mehrdad Afshari

  Hopefully, I'm going to finish my undergraduate studies next semester and I'm thinking about the topic of my final project. And yes, I've read the questions with duplicate title. I'm asking this from a bit different viewpoint, so it's not an exact dupe. I've spent at least half of my life coding stuff in different languages and frameworks so I'm not looking at this project as a way to learn much about coding and preparing for real world apps or such. I've done lots of those already. But since I have to do it to complete my degree, I felt I should spend my time doing something useful instead of throwing the whole thing out. I'm planning to make it an open source project or a hosted Web app (depending on the type) if I can make a high quality thing out of it, so I decided to ask StackOverflow what could make a useful project. Situation I've plenty of freedom about the topic. They also require 30-40 pages of text describing the project. I have the following points in mind (the more satisfied, the better): Something useful for software development Something that benefits the community Having academic value is great Shouldn't take more than a month of development (I know I'm lazy). Shouldn't be related to advanced theoretical stuff (soft computing, fuzzy logic, neural networks, ...). I've been a business-oriented software developer. It should be software oriented. While I love hacking microcontrollers and other fun embedded electronic things, I'm not really good at soldering and things like that. I'm leaning toward a Web application (think StackOverflow, PasteBin, NerdDinner, things like those). Technology It's probably going to be done in .NET (C#, F#) and Windows platform. If I really like the project (cool low level hacking), I might actually slip to C/C++. But really, C# is what I'm efficient at. Ideas Programming language, parsing and compiler related stuff: Designing a domain specific programming language and compiler Templating language compiled to C# or IL Database tools and related code generation stuff Web related technologies: ASP.NET MVC View engine doing something cool (don't know what exactly...) Specific-purpose, small, fast ASP.NET-based Web framework Applications: Visual Studio plugin to integrate with Bazaar (it's too much work, I think). ASP.NET based, jQuery-powered issue tracker (and possibly, project lifecycle management as a whole - poor man's TFS) Others: Something related to GPGPU Looking forward for great ideas! Unfortunately, I can't help on a currently existing project. I need to start my own to prevent further problems (as it's an undergrad project, nevertheless).

• Qt vs .NET - plz no n00bs who don't know wtf they're talking about [closed]

  - by Pirate for Profit

  Man in all these Qt vs. .NET discussions 90% these people don't know WTF they're talking about. Trying to get a real comparison chart going before we embark on a major fucking project. And yes I'm drunk, and yes I use cocaine. Event Handling In Qt the event handling system you just emit signals when something cool happens and then catch them in slots, for instance emit valueChanged(int percent, bool something); and void MyCatcherObj::valueChanged(int p, bool ok){} blocking them and disconnecting them when needed, doing it across threads... once you get the hang of it, it just seems a lot more natural and intuitive than the way the .NET event handling is set up (you know, object sender, CustomEventArgs e). And I'm not just talking about syntax, because in the end the .NET delegate crap is the bomb. I'm also talking about in more than just reflection (because, yes, .NET obviously has much stronger reflection capabilities). I'm talking about in the way the system feels to a human being. Qt wins hands down i m o. Basically, the footprints make more sense and you can visualize the project easier without the clunky event handling system. I wish I could it explain it better. The only thing is, I do love some of the ease of C# compared to C++ and .NET's assembly architecture. That is a big bonus for modular projects, which are a PITA to do in C++. Database Ease of Doing Crap Also what about datasets and database manipulations. I think .net wins here but I'm not sure. Threading/Conccurency How do you guys think of the threading? In .NET, all I've ever done is make like a list of master worker threads with locks. I like QConcurrentFramework, you don't worry about locks or anything, and with the ease of the signal slot system across threads it's nice to get notified about the progress of things. Memory Usage Also what do you think of the overall memory usage comparison. Is the .NET garbage collector pretty on the ball and quick compared to the instantaneous nature of native memory management? Or does it just let programs leak up a storm and lag the computer then clean it up when it's about to really lag? However, I am a n00b who doesn't know what I'm talking about, please school me on the subject.

• How to avoid open-redirect vulnerability and safely redirect on successful login (HINT: ASP.NET MVC

  - by Brad B.

  Normally, when a site requires that you are logged in before you can access a certain page, you are taken to the login screen and after successfully authenticating yourself, you are redirected back to the originally requested page. This is great for usability - but without careful scrutiny, this feature can easily become an open redirect vulnerability. Sadly, for an example of this vulnerability, look no further than the default LogOn action provided by ASP.NET MVC 2: [HttpPost] public ActionResult LogOn(LogOnModel model, string returnUrl) { if (ModelState.IsValid) { if (MembershipService.ValidateUser(model.UserName, model.Password)) { FormsService.SignIn(model.UserName, model.RememberMe); if (!String.IsNullOrEmpty(returnUrl)) { return Redirect(returnUrl); // open redirect vulnerability HERE } else { return RedirectToAction("Index", "Home"); } } else { ModelState.AddModelError("", "User name or password incorrect..."); } } return View(model); } If a user is successfully authenticated, they are redirected to "returnUrl" (if it was provided via the login form submission). Here is a simple example attack (one of many, actually) that exploits this vulnerability: Attacker, pretending to be victim's bank, sends an email to victim containing a link, like this: http://www.mybank.com/logon?returnUrl=http://www.badsite.com Having been taught to verify the ENTIRE domain name (e.g., google.com = GOOD, google.com.as31x.example.com = BAD), the victim knows the link is OK - there isn't any tricky sub-domain phishing going on. The victim clicks the link, sees their actual familiar banking website and is asked to logon Victim logs on and is subsequently redirected to http://www.badsite.com which is made to look exactly like victim's bank's website, so victim doesn't know he is now on a different site. http://www.badsite.com says something like "We need to update our records - please type in some extremely personal information below: [ssn], [address], [phone number], etc." Victim, still thinking he is on his banking website, falls for the ploy and provides attacker with the information Any ideas on how to maintain this redirect-on-successful-login functionality yet avoid the open-redirect vulnerability? I'm leaning toward the option of splitting the "returnUrl" parameter into controller/action parts and use "RedirectToRouteResult" instead of simply "Redirect". Does this approach open any new vulnerabilities? Side note: I know this open-redirect may not seem to be a big deal compared to the likes of XSS and CSRF, but us developers are the only thing protecting our customers from the bad guys - anything we can do to make the bad guys' job harder is a win in my book. Thanks, Brad

• Best programming aids for a quadriplegic programmer

  - by Peter Rowell

  Before you jump to conclusions, yes, this is programming related. It covers a situation that comes under the heading of, "There, but for the grace of God, go you or I." This is brand new territory for me so I'm asking for some serious help here. A young man, Honza Ripa, in a nearby town did the classic Dumb Thing two weeks after graduating from High School -- he dove into shallow water in the Russian River and had a C-4/C-5 break, sometimes called a Swimming Pool break. In a matter of seconds he went from an exceptional golfer and wrestler to a quadriplegic. (Read the story ... all of us should have been so lucky as to have a girlfriend like Brianna.) That was 10 months ago and he has regained only tiny amounts of control of his right index finger and a couple of other hand/foot motions, none of them fine-grained. His total control of his computer (currently running Win7, but we can change that as needed) is via voice command. Honza's not dumb. He had a 3.7 GPA with AP math and physics. The Problems: Since all of his input is via voice command, he is concerned that the predominance of special characters in programming will require vast amount of verbose commands. Does anyone know of any well done voice input system specifically designed for programmers? I'm thinking about something that might be modal--e.g. you say "Python input" and it goes into a macro mode for doing class definitions, etc. Given all of the RSI in programmer-land there's got to be something out there. What OS(es) does it run on? I am planning on teaching him Python, which is my preferred language for programming and teaching. Are there any applications / whatevers that are written in Python and would be a particularly good match for engaging him mentally while supporting his disability? One of his expressed interests is in stock investing, but that not might be a good starting point for a brand-new programmer. There are a lot of environments (Flash, JavaScript, etc) that are not particularly friendly to people with accessibility challenges. I vaguely remember (but cannot find) a research project that basically created an overlay system on top of a screen environment and then allowed macro command construction on top of the screen image. If we can get/train this system, we may be able to remove many hurdles to using the net. I am particularly interested in finding open source Python-based robotics and robotic prostheses projects so that he can simultaneously learn advanced programming concepts while learning to solve some of his own immediate problems. I've done a ton of googling on this, but I know there things I'm missing. I'm asking the SO community to step up to the plate here. I know this group has the answers, so let me hear them! Overwhelm me with the opportunities that any of us might have/need to still program after such a life-changing event.

• How can I do something ~after~ an event has fired in C#?

  - by Siracuse

  I'm using the following project to handle global keyboard and mouse hooking in my C# application. This project is basically a wrapper around the Win API call SetWindowsHookEx using either the WH_MOUSE_LL or WH_KEYBOARD_LL constants. It also manages certain state and generally makes this kind of hooking pretty pain free. I'm using this for a mouse gesture recognition software I'm working on. Basically, I have it setup so it detects when a global hotkey is pressed down (say CTRL), then the user moves the mouse in the shape of a pre-defined gesture and then releases global hotkey. The event for the KeyDown is processed and tells my program to start recording the mouse locations until it receives the KeyUp event. This is working fine and it allows an easy way for users to enter a mouse-gesture mode. Once the KeyUp event fires and it detects the appropriate gesture, it is suppose to send certain keystrokes to the active window that the user has defined for that particular gesture they just drew. I'm using the SendKeys.Send/SendWait methods to send output to the current window. My problem is this: When the user releases their global hotkey (say CTRL), it fires the KeyUp event. My program takes its recorded mouse points and detects the relevant gesture and attempts to send the correct input via SendKeys. However, because all of this is in the KeyUp event, that global hotkey hasn't finished being processed. So, for example if I defined a gesture to send the key "A" when it is detected, and my global hotkey is CTRL, when it is detected SendKeys will send "A" but while CTRL is still "down". So, instead of just sending A, I'm getting CTRL-A. So, in this example, instead of physically sending the single character "A" it is selecting-all via the CTRL-A shortcut. Even though the user has released the CTRL (global hotkey), it is still being considered down by the system. Once my KeyUp event fires, how can I have my program wait some period of time or for some event so I can be sure that the global hotkey is truly no longer being registered by the system, and only then sending the correct input via SendKeys?

• Add Silverlight Bing Maps Control to Windows Mobile 7 application

  - by Jacob

  I know the bits just came out today, but one of the first things I want to do with the newly released Windows Mobile 7 SDK is put a map up on the screen and mess around. I've downloaded the latest version of the Silverlight Maps Control and added the references to my application.

• Scheme Formatting Help

  - by Logan

  I've been working on a project for school that takes functions from a class file and turns them into object/classes. The assignment is all about object oriented programming in scheme. My problem however is that my code doesn't format right. The output it gives me whenever I give it a file to pass in wraps the methods of the class in a list, making it so that the class never really gets declared. I can't for the life of me figure out how to get the parenthesis wrapping the method list to remove. I would really appreciate any help. Below is the code and the class file. ;;;; PART1 --- A super-easy set of classes. Just models points and lines. Tests all of the ;; basics of class behavior without touching on anything particularly complex.

• Using Apple’s Bonjour service from .NET?

  - by Martín Marconcini

  I have an iPhone app that publishes through Bonjour. The Mac counterpart works, they sync and exchange data. Now I have to port that little Mac app to Windows. I’ve decided to go with .NET (because that’s what I know). The app is not complex, but I’m in the early stages. I need to browse/discover Bonjour services. For this task, I’ve downloaded Mono.Zeroconf and Apple’s latest SDK (which includes a couple of C# Samples). I’m not really pasting code because I’m really copy/pasting the samples. In fact, Mono.Zeroconf has a MZClient.exe that can be used to test “all the API”. My 1st test was -on the same box- open two cmd.exe and launch a MZclient registering a service and on the other, launch it and “discover it”. It doesn’t work. Here’s the server: C:\MZ>MZClient -v -p "_http._tcp 80 mysimpleweb” *** Registering name = 'mysimpleweb', type = '_http._tcp', domain = 'local.' *** Registered name = ‘mysimpleweb’ On the other terminal: c:\MZ>MZClient -v -t "_http._tcp" Creating a ServiceBrowser with the following settings: Interface = 0 (All) Address Protocol = Any Domain = local Registration Type = _http._tcp Resolve Shares = False Hit ^C when you're bored waiting for responses. And that’s it. Nothing happens. I’ve of course tried with different services to no avail. Even played a little bit with that domain thing. Remember this is the same box. I tried on another computer, because this was a VM inside OSX, so I went ahead and tried on a “pure” win XP. Nothing. note: I have Apple Bonjour Service (up and running) and also the Apple SDK (installed later). Given that this didn’t work, I went ahead and decided to try the Apple SDK which has an Interop and a few pre-compiled samples (and its source code). Short story, neither the mDSNBrowser.exe nor the SimpleChat.exe work/see/discover anything. My box is a Win7 under Parallels, but that doesn’t seem to be affecting anything, given that the native XP exhibits the same problems. What am I doing so awfully wrong?

• Classic ASP vs. ASP.NET encryption options

  - by harrije

  I'm working on a web site where the new pages are ASP.NET and the legacy pages are Classic ASP. Being new to development in the Windows env, I've been studying the latest technology, i.e. .NET and I become like a deer in headlights when ever legacy issues come up regarding COM objects. Security on the website is an abomination, but I've easily encrypted the connectionStrings in the web.config file per http://www.4guysfromrolla.com/articles/021506-1.aspx based on DPAPI machine mode. I understand this approach is not the most secure, but it's better than nothing which is what it was for the ASP.NET pages. Now, I question how to do similar encryption for the connection strings used by the Classic ASP pages. A complicating factor is that the web sited is hosted where I do not have admin permissions or even command line access, just FTP. Moreover I want to avoid managing the key. My research has found: DPAPI with COM interop. Seems like this should already be available, but the only thing I could find discussing this is CyptoUtility (see http://msdn.microsoft.com/en-us/magazine/cc163884.aspx) which is not installed on the hosting server. There are plenty of other third party COM objects, e.g. Crypto from Dalun Software http://www.dalun.com, but these aren't on the hosted server either, and they look to me to require you to do some kind of key management. There is CAPICOM on the hosted server, but M$ has deprecated it and many report it is not the easiest to use. It is not clear to me whether I can avoid key management with CAPICOM similar to using DPAPI for ASP.NET. If anyone happens to know, please clue me in. I could write an web service in ASP.NET and have the classic ASP pages use it to get the decrypted connection strings and then store those in an application variable. I would not need to use SSL since I could use localhost and nothing would be sent over the internet. In the simpliest form I could implement what someone termed a poor man's version based on a simple XML stream, however, I really was looking to avoid any development since I find it hard to believe there is not a simple solution for Classic ASP like there is for ASP.NET. Maybe I'm missing some options... Recommendations are requested...

• decrypt an encrypted value ?

  - by jim

  I have an old Paradox database (I can convert it to Access 2007) which contains more then 200,000 records. This database has two columns: the first one is named "Word" and the second one is named "Mean". It is a dictionary database and my client wants to convert this old database to ASP.NET and SQL. However, we don't know what key or method is used to encrypt or encode the "Mean" column which is in the Unicode format. The software itself has been written in Delphi 7 and we don't have the source code. My client only knows the credentials for logging in to database. The problem is decoding the Mean column. What I do have is the compiled windows application and the Paradox database. This software can decode the "Mean" column for each "Word" so the method and/or key is in its own compiled code(.exe) or one of the files in its directory. For example, we know that in the following row the "Zymurgy" exactly means "???? ??? ????? ?? ???? ????, ????? ?????" since the application translates it like that. Here is what the record looks like when I open the database in Access: Word Mean Zymurgy 5OBnGguKPdDAd7L2lnvd9Lnf1mdd2zDBQRxngsCuirK5h91sVmy0kpRcue/+ql9ORmP99Mn/QZ4= Therefore we're trying to discover how the value in the Mean column is converted to "???? ??? ????? ?? ???? ????, ????? ?????". I think the "Mean" column value in above row is encoded in Base64 string format, but decoding the Base64 string does not yet result in the expected text. The extensions for files in the win app directory are dll, CCC, DAT, exe (other than the main app file), SYS, FAM, MB, PX, TV, VAL. Any kind of help is appreciated. Additional information: guys! the creators are not that stupid to save the values only in encoded form. they're definitely encrypted them. so i guess we have to look for the key.

• jQuery galleria plugin with dynamically loaded images

  - by panas

  I'm using the Galleria plugin with jQuery to create my image gallery. I'm trying to get load images dynamically from the user's selection into the DOM and have the gallery auto-update to display those new images but it's not working. Firebug shows the images are successfully loading into the DOM but Galleria displays no thumbnails. I need a way to reload Galleria to display the new images. /* ---- Gallery Code ---- */ if ($(this).find('div').attr('title') == 'photogallery' && $('.galleria_container').length == 0) { $('.gallery').galleria( { history : false, clickNext : true, onImage : function(image,caption,thumb) { if(! ($.browser.mozilla && navigator.appVersion.indexOf("Win")!=-1) ) { image.css('display','none').fadeIn(1000); } var _li = thumb.parents('li'); caption.css('display','none').fadeIn(1000); _li.siblings().children('img.selected').fadeTo(500,0.3); thumb.fadeTo('fast',1).addClass('selected'); image.attr('title','Next image >>'); }, onThumb : function(thumb) { var _li = thumb.parents('li'); var _fadeTo = _li.is('.active') ? '1' : '0.3'; thumb.css({display:'none',opacity:_fadeTo}).fadeIn(1500); thumb.hover ( function() { thumb.fadeTo('fast',1); }, function() { _li.not('.active').children('img').fadeTo('fast',0.3); } // don't fade out if the parent is active ) } }); } /* ---- Gallery Selector ---- */ $(document).ready(function() { var galleryImages = new Object(); <?php echo $myGal; ?> function setImages(type) { var image = ''; for (var i = 0; i < galleryImages[type].length; i++) { image += '<li><img src="' + galleryImages[type][i] + '"></li>'; } $('ul.gallery').html(image); } $('ul.menu-horiz li ul li').click(function() { setImages($(this).attr('rel')); }); }); The PHP code you see just creates an array of images. So to summarise my question: How can I reload Galleria once the new images have been loaded into the DOM?

• Using commit monitors as a form of code review

  - by Jeff Dege

  I'm working in a small company - four developers, working on a variety of projects. We've been looking at what we can do as cost-effective methods of process improvement, and an idea came up. Given what we do, we often have single developers working on parts of a system, independently of the other developers. This can have a number of negative affects: A developer might not be fully aware of the context in which a change is being implemented, and make the change in a way that will meet the current customer's needs, but will break functionality that other customers depend on. A developer might make a change that breaks the current architectural design, introducing a dependency that will cause problems in future development. Other developers might not be aware of how the system has changed, in areas that they have not worked on. We've talked about doing code reviews, as a way of dealing with these issues. But we've not had much success when we tried. It takes a lot of time to prepare a change for a code review, and it takes everybody out of production while the review is being performed. And the benefits of any review we've tried has been minimal. We're using Subversion (with TortioseSVN) as our VCS. I've been looking at the SubVersion CommitMonitor tool, and wondering whether it might work as a sort of poor-man's code review. It lists every commit made on the repository, allowing someone to see the changes that have been made, the log messages made for that change, the files that were included in the change, and the specific lines in each file that were changed. Rather than scheduling a meeting, trying to get everybody together to review every change, we could just have every developer review every other developer's commits, at whatever time was convenient. This would keep every developer abreast of what changes were being made elsewhere in the system, and would have every change reviewed for customer conflicts and design consistency, at a fairly low cost. If someone saw a problem with the code that was being checked in, he could discuss it with the developer who did the commit, or more likely, schedule a meeting to discuss how the new feature could be implemented in a way that would not impact other users or screw up the architecture. Anyone else doing anything like this, using commit monitors for such a purpose?

• Cannot add Silverlight Maps Control to Windows Mobile 7 application

  I know the bits just came out today, but one of the first things I want to do with the newly released Windows Mobile 7 SDK is put a map up on the screen and mess around. I've downloaded the latest version of the Silverlight Maps Control and added the references to my application.

• Problems related to showing MessageBox from non-GUI threads

  - by Hans Løken

  I'm working on a heavily data-bound Win.Forms application where I've found some strange behavior. The app has separate I/O threads receiving updates through asynchronous web-requests which it then sends to the main/GUI thread for processing and updating of application-wide data-stores (which in turn may be data-bound to various GUI-elements, etc.). The server at the other end of the web-requests requires periodic requests or the session times out. I've gone through several attempted solutions of dealing with thread-issues etc. and I've observed the following behavior: If I use Control.Invoke for sending updates from I/O-thread(s) to main-thread and this update causes a MessageBox to be shown the main form's message pump stops until the user clicks the ok-button. This also blocks the I/O-thread from continuing eventually leading to timeouts on the server. If I use Control.BeginInvoke for sending updates from I/O-thread(s) to main-thread the main form's message pump does not stop, but if the processing of an update leads to a messagebox being shown, the processing of the rest of that update is halted until the user clicks ok. Since the I/O-threads keep running and the message pump keeps processing messages several BeginInvoke's for updates may be called before the one with the message box is finished. This leads to out-of-sequence updates which is unacceptable. I/O-threads add updates to a blocking queue (very similar to http://stackoverflow.com/questions/530211/creating-a-blocking-queuet-in-net/530228#530228). GUI-thread uses a Forms.Timer that periodically applies all updates in the blocking queue. This solution solves both the problem of blocking I/O threads and sequentiality of updates i.e. next update will be never be started until previous is finished. However, there is a small performance cost as well as introducing a latency in showing updates that is unacceptable in the long run. I would like update-processing in the main-thread to be event-driven rather than polling. So to my question. How should I do this to: avoid blocking the I/O-threads guarantee that updates are finished in-sequence keep the main message pump running while showing a message box as a result of an update.

• Python, SWIG and other strange things

  - by wanderameise

  hey, I have a firmware for an USB module I can already control by visual C. Now I want to port this to python. for this I need the octopus library which is written in c. I found a file called octopus_wrap which was created by SWIG! then I found a makefile which says: python2.5: swig -python -outdir ./ ../octopus.i gcc -fPIC -c ../../liboctopus/src/octopus.c gcc -fPIC -c ../octopus_wrap.c -I /usr/include/python2.5 gcc -fPIC -shared octopus_wrap.o octopus.o /usr/lib/libusb.so -o _octopus.so python2.4: swig -python -outdir ./ ../octopus.i gcc -fPIC -c ../../liboctopus/src/octopus.c gcc -fPIC -c ../octopus_wrap.c -I /usr/include/python2.4 gcc -fPIC -shared octopus_wrap.o octopus.o /usr/lib/libusb.so -o _octopus.so win: gcc -fPIC -c ../../liboctopus/src/octopus.c -I /c/Programme/libusb-win32-device-bin-0.1.10.1/include gcc -fPIC -c octopus_wrap.c -I /c/Python25/libs -lpython25 -I/c/Python25/include -I /c/Programme/libusb-win32-device-bin-0.1.10.1/include gcc -fPIC -shared *.o -o _octopus.pyd -L/c/Python25/libs -lpython25 -lusb -L/c/Programme/libusb-win32-device-bin-0.1.10.1/lib/gcc clean: rm -f octopus* _octopus* install_python2.4: cp _octopus.so /usr/local/lib/python2.4/site-packages/ cp octopus.py /usr/local/lib/python2.4/site-packages/ install_python2.5: cp _octopus.so /usr/local/lib/python2.5/site-packages/ cp octopus.py /usr/local/lib/python2.5/site-packages/ I dont know how to handle this but as far as I can see octopus.py and _octopus.so are the resulting output files which are relevant to python right? luckily someone already did that and so I put those 2 files to my "python26/lib" folder (hope it doesnt matter if it´s python 2.5 or 2.6?!) So when working with the USB device the octopus.py is the library to work with! Importing this file makes several problems: >>> Traceback (most recent call last): File "C:\Users\ameise\My Dropbox\µC\AVR\OCTOPUS\octopususb-0.5\demos\python \blink_status.py", line 8, in <module> from octopus import * File "C:\Python26\lib\octopus.py", line 7, in <module> import _octopus ImportError: DLL load failed: module not found. and here´s the related line 7 : import _octopus So there´s a problem considering the .so file! What could be my next step? I know that´s a lot of confusing stuff but I hope anyone of you could bring some light in my mind! thy in advance

• Is it worth moving from stored procedures to linq ?

  - by Josef

  I'm looking at standardizing programming in an organisaiton. Half uses stored procedures and the other half Linq. From what i've read there is still some debate going on on this topic. My concern is that MS is trying to slip in it's own proprietry query language 'linq' to make SQL redundant. If a few years back microsoft had tried to win customers from oracle and sybase with their MSSQL database and stated that it didn't use SQL by their own proprietry query langues ie linq. I doubt many would have switched. I believe that is exactly what is happening now by introducting it into the applicaiton business layer. I have used MS for many years but there is one gripe that I have with them and that is that they change their direction a lot. By a lot I mean new releases of .net, silverlight etc are more than 30% different from previous version. So by the time you become productive a new release is on the way. As things stand now a web developer using .net would need to know either vb.net or c#, xml, xaml,javascript,html, sql and now linq. That doesn't make for good productivity in my books. My concern is that once we all start using linq MS will start changing it between releases. and it will become an ever changing landscape. I believe that 'linq to sql' has already been deprecated. At leas with SQL we are dealing with a more stable and standardized language. Are we looking at a programming revolution or a marketing campaign? As far as I know other languages like Cobol have stayed the same for years. A cobol program from 20 years ago could pick up todays code and start working on it. Could a Vb3 person work on a modern .net web app ? Would these large changes need to be made if the underlying original foundation had been sound ? I worry about following MS shaking roadmap with it's deadends and double backs. are there any architects out there who feel the same ? regards Josef

• Why do I get extra, unexpected results with my ack regex?

  - by Gauthier

  I'm finally learning regexps and training with ack. I believe this uses Perl regexp. I want to match all lines where the first non-blank characters are if (<word> !, with any number of spaces in between the elements. This is what I came up with: ^[ \t]*if *\(\w+ *! It only nearly worked. ^[ \t]* is wrong, since it matches one or none [space or tab]. What I want is to match anything that may contain only space or tab (or nothing). For example these should not match: // if (asdf != 0) else if (asdf != 1) How can I modify my regexp for that? EDIT adding command line ack -i --group -a '^\s*if *\(\w+ *!' c:/work/proj/proj Note the single quotes, I'm not so sure about them anymore. My search base is a larger code base. It does include matching expressions (quite some), but even for example: 274: }else if (y != 0) , which I get as a result of the above command. EDIT adding the result of mobrule's test Mobrule, thanks for providing me a text to test on. I'll copy here what I get on my prompt: C:\Temp\regex>more ack.test # ack.test if (asdf != 0) # no spaces - ok if (asdf != 0) # single space - ok if (asdf != 0) # single tab - ok if (asdf != 0) # multiple space - ok if (asdf != 0) # multiple tab - ok if (asdf != 0) # spaces + tab ok if (asdf != 0) # tab + space ok if (asdf != 0) # space + tab + space ok // if (asdf != 0) # not ok } else if (asdf != 0) # not ok C:\Temp\regex>ack '^[ \t]*if *\(\w+ *!' ack.test C:\Temp\regex>"C:\Program\git\bin\perl.exe" C:\bat\ack.pl '[ \t]*if *\(\w+ *!' a ck.test if (asdf != 0) # no spaces - ok if (asdf != 0) # single space - ok if (asdf != 0) # single tab - ok if (asdf != 0) # multiple space - ok if (asdf != 0) # multiple tab - ok if (asdf != 0) # spaces + tab ok if (asdf != 0) # tab + space ok if (asdf != 0) # space + tab + space ok // if (asdf != 0) # not ok } else if (asdf != 0) # not ok The problem is in my call to my ack.bat! ack.bat contains: "C:\Program\git\bin\perl.exe" C:\bat\ack.pl %* Although I call with a caret, it gets away at the call of the bat file! Escaping the caret with ^^ does not work. Quoting the regex with " " instead of ' ' works. My problem was a DOS/win problem, sorry for bothering you all for that.
