  • What are the dark corners of Vim your mom never told you about?

    - by Sasha
    There is a plethora of questions where people talk about common tricks, notably this one. However, I don't refer to commonly used shortcuts that a noob would find cool. I am talking about a seasoned unix user (be she/he a developer, admin, both, etc), who thinks (s)he knows something 99% of us never heard or dreamed about. Something that not only makes his/her work easier, but also is COOL and hackish. After all, vim resides in the most dark-corner-rich OS in the world, thus it should have intricacies that only a few privileged know about and want to share with us.

  • From actionscript to google's datastore through java.

    - by Jonathan
    I'm working on a flash game written in pure actionscript 3.0 in Flex. I've just finished implementing replays for the game, but want to store the top 10 hiscores' replay data on my google-app-engine'd website. I'm using Java for the app-engine stuff in Eclipse in java but I have no idea how to deal with communicating to my java code from my actionscript code. I'll need to both read and write from actionscript - java - datastore. Does anyone have any experience with this? For note, I'm horribly noob with anything to do with web development. I hear you can pass arguments to a URL when calling it, comparable to command-line arguments on a desktop executable and if so then sending all the data as a large string would be doable... The question then would be how to call a url from AS3 code with additional data and then how to catch that on the java side. Thanks to anyone who can help. Jono

  • how can i make a link in XML

    - by Chi
    I have this flash website that comes with XML. The website is predefined in such a way that when I hoover the mouse cursor over some pictures or text, it will show the pointing hand, thus meaning it's a clickable link. Originally, it would look like so: After I changed the link part, it becomes: However, this seems not to be working (google link is just an example). The pointing hand is still showing, but when I click on it, nothing happens. So my question is quite simple, how do I link in XML (sorry if all this sounded rather stupid, I'm a noob)

  • How do you install Castle Windsor IOC?

    - by user300266
    I'm currently reading Pro ASP.NET MVC Framework by Sanderson. In the book he recommends setting up IoC using Castle Windsor, and he points out that the download automatically installs it and registers the Castle DLLs in the GAC. Well, at this point in time (5/4/2010), the Castle Project no longer has a downloadable installer that sets this up. Its all broken out into their individual subprojects with the raw files contained in zipped folders. Sadly there's no installation documentation that I can find about how to set it up. Being the noob that I am, I'm stuck and now forced to ask #1 where should castle windsor live on my hard drive? #2 how do I manually register the dlls properly? And, #3 should I be angry at the project maintainers for their oversight? Here's the link: http://www.castleproject.org/castle/download.html

  • Trying to find a good strategy using Git for personal development on local/personal machine

    - by AJ
    A noob here. I have a personal Macbook and I want to use Git to track the changes etc. I want to just init a repo on my macbook and work there. Is this a good idea? What if: I have a main repo somewhere in my Macbook HD, like, /Users/user/projects/project1 and clone it to another area on my macbook where I actually perform development? But there is a lot of redundancy in this. I am a little confused and want to know what are the usual steps folks take in a similar personal development environment. Thanks a lot.

  • Specify Action on sub-controller when using Html.RenderAction

    - by iammaz
    I have a UserControl that I call with Html.RenderAction(...), so far so good.. Then I want to specify in the user control, which action should be used Html.BeginForm("DeleteComment", "Comments", new { Id = "frmDelete" }, FormMethod.Post);%> <%= Html.SubmitImage( "imgbtnDelete", "/image.png", new { ... })%> <% Html.EndForm(); %> And therein lies my problem; this calls the user control's controller/action. What I want to happen is to call the pages action first and then be able to specify what action to call on the user control's controller. Is this possible?? Thanks from an MVC noob

  • Introduction tutorial/s for web accessibility?

    - by Arnis L.
    I've ignored this topic for really long time and I would like to get at least basic instincts on this subject (You know - more than "don't forget to add alt on images"). Assuming that I'm complete noob on this, where should i look first? Please, do not just post some ISO standards, html spec or whatnot. That will just recoil any interest. I'm looking for gentle push with guidelines where to look next. P.s. I did try to find duplicate question/s w/o any luck.

  • Conversion of BizTalk Projects to Use the New WCF-SAP Adaptor

    - by Geordie
    We are in the process of upgrading our BizTalk Environment from BizTalk 2006 R2 to BizTalk 2010. The SAP adaptor in BizTalk 2010 is an all new and more powerful WCF-SAP adaptor. When my colleagues tested out the new adaptor they discovered that the format of the data extracted from SAP was not identical to the old adaptor. This is not a big deal if the structure of the messages from SAP is simple. In this case we were receiving the delivery and invoice iDocs. Both these structures are complex especially the delivery document. Over the past few years I have tweaked the delivery mapping to remove bugs from original mapping. The idea of redoing these maps did not appeal and due to the current work load was not even an option. I opted for a rather crude alternative of pulling in the iDoc in the new typed format and then adding a static map at the start of the orchestration to convert the data to the old schema.  Note WCF-SAP data formats (on the binding tab of the configuration dialog box is the ‘RecieiveIdocFormat’ field): Typed:  Returns a XML document with the hierarchy represented in XML and all fields being represented by XML tags. RFC: Returns an XML document with the hierarchy represented in XML but the iDoc lines in flat file format. String: This returns the iDoc in a format that is closest to the original flat file format but is still wrapped with some top level XML tags. The files also contained some strange characters at the end of each line. I started with the invoice document and it was quite straight forward to add the mapping but this is where my problems started. The orchestrations for these documents are dynamic and so require the identity of the partner to be able to correctly configure the orchestration. The partner identity is in the EDI_DC40 segment of the iDoc. In the old project the RECPRN node of the segment was promoted. The code to set a variable to the partner ID was now failing. After lot of head scratching I discovered the problem was due to the addition of Namespaces to the fields in the EDI_DC40 segment. To overcome this I needed to use an xPath query with a Namespace Manager. This had to be done in custom code. I now tried to repeat the process with the delivery document. Unfortunately when we tried to get sample typed data from SAP an exception was thrown. The adapter "WCF-SAP" raised an error message. Details "Microsoft.ServiceModel.Channels.Common.XmlReaderGenerationException: The segment or group definition E2EDKA1001 was not found in the IDoc metadata. The UniqueId of the IDoc type is: IDOCTYP/3/DESADV01/ZASNEXT1/640. For Receive operations, the SAP adapter does not support unreleased segments.   Our guess is that when the WCF-SAP adaptor tries to down load the data it retrieves a data schema from SAP. For some reason the schema does not match the data. This may be due to the version of SAP we are running or due to a customization. Either way resolving this problem did not look easy. When doing some research on this problem I found an article showing me how to get the data from SAP using the WCF-SAP adaptor without any XML tags. http://blogs.msdn.com/b/adapters/archive/2007/10/05/receiving-idocs-getting-the-raw-idoc-data.aspx Reproduction of Mustansir blog: Since the WCF based SAP Adapter is ... well, WCF based, all data flowing in and out of the adapter is encapsulated within a SOAP message. Which means there are those pesky xml tags all over the place. If you want to receive an Idoc from SAP, you can receive it in "Typed" format (in which case each column in each segment of the idoc appears within its own xml tag), or you can receive it in "String" format (in which case there are just 2 xml tags at the top, the raw xml data in string/flat file format, and the 2 closing xml tags). In "String" format, an incoming idoc (for ORDERS05, containing 5 data records) would look like: <ReceiveIdoc ><idocData>EDI_DC40 8000000000001064985620 E2EDK01005 800000000000106498500000100000001 E2EDK14 8000000000001064985000002000000020111000 E2EDK14 8000000000001064985000003000000020081000 E2EDK14 80000000000010649850000040000000200710 E2EDK14 80000000000010649850000050000000200600</idocData></ReceiveIdoc> (I have trimmed part of the control record so that it fits cleanly here on one line). Now, you're only interested in the IDOC data, and don't care much for the XML tags. It isn't that difficult to write your own pipeline component, or even some logic in the orchestration to remove the tags, right? Well, you don't need to write any extra code at all - the WCF Adapter can help you here! During the configuration of your one-way Receive Location using WCF-Custom, navigate to the Messages tab. Under the section "Inbound BizTalk Messge Body", select the "Path" radio button, and: (a) Enter the body path expression as: /*[local-name()='ReceiveIdoc']/*[local-name()='idocData'] (b) Choose "String" for the Node Encoding. What we've done is, used an XPATH to pull out the value of the "idocData" node from the XML. Your Receive Location will now emit text containing only the idoc data. You can at this point, for example, put the Flat File Pipeline component to convert the flat text into a different xml format based on some other schema you already have, and receive your version of the xml formatted message in your orchestration.   This was potentially a much easier solution than adding the static maps to the orchestrations and overcame the issue with ‘Typed’ delivery documents. Not quite so fast… Note: When I followed Mustansir’s blog the characters at the end of each line disappeared. After configuring the adaptor and passing the iDoc data into the original flat file receive pipelines I was receiving exceptions. There was a failure executing the receive pipeline: "PAPINETPipelines.DeliveryFlatFileReceive, CustomerIntegration2.PAPINET.Pipelines, Version=1.0.0.0, Culture=neutral, PublicKeyToken=4ca3635fbf092bbb" Source: "Pipeline " Receive Port: "recSAP_Delivery" URI: "D:\CustomerIntegration2\SAP\Delivery\*.xml" Reason: An error occurred when parsing the incoming document: "Unexpected data found while looking for: 'Z2EDPZ7' The current definition being parsed is E2EDP07GRP. The stream offset where the error occured is 8859. The line number where the error occured is 23. The column where the error occured is 0.". Although the new flat file looked the same as the old one there was a differences. In the original file all lines in the document were exactly 1064 character long. In the new file all lines were truncated to the last alphanumeric character. The final piece of the puzzle was to add a custom pipeline component to pad all the lines to 1064 characters. This component was added to the decode node of the custom delivery and invoice flat file disassembler pipelines. Execute method of the custom pipeline component: public IBaseMessage Execute(IPipelineContext pc, IBaseMessage inmsg) { //Convert Stream to a string Stream s = null; IBaseMessagePart bodyPart = inmsg.BodyPart;   // NOTE inmsg.BodyPart.Data is implemented only as a setter in the http adapter API and a //getter and setter for the file adapter. Use GetOriginalDataStream to get data instead. if (bodyPart != null) s = bodyPart.GetOriginalDataStream();   string newMsg = string.Empty; string strLine; try { StreamReader sr = new StreamReader(s); strLine = sr.ReadLine(); while (strLine != null) { //Execute padding code if (strLine != null) strLine = strLine.PadRight(1064, ' ') + "\r\n"; newMsg += strLine; strLine = sr.ReadLine(); } sr.Close(); } catch (IOException ex) { throw new Exception("Error occured trying to pad the message to 1064 charactors"); }   //Convert back to stream and set to Data property inmsg.BodyPart.Data = new MemoryStream(Encoding.UTF8.GetBytes(newMsg)); ; //reset the position of the stream to zero inmsg.BodyPart.Data.Position = 0; return inmsg; }

  • Feedback Filtration&ndash;Processing Negative Comments for Positive Gains

    - by D'Arcy Lussier
    After doing 7 conferences, 5 code camps, and countless user group events, I feel that this is a post I need to write. I actually toyed with other names for this post, however those names would just lend itself to the type of behaviour I want people to avoid – the reactionary, emotional response that speaks to some deeper issue beyond immediate facts and context. Humans are incredibly complex creatures. We’re also emotional, which serves us well in certain situations but can hinder us in others. Those of us in leadership build up a thick skin because we tend to encounter those reactionary, emotional responses more often, and we’re held to a higher standard because of our positions. While we could react with emotion ourselves, as the saying goes – fighting fire with fire just makes a bigger fire. So in this post I’ll share my thought process for dealing with negative feedback/comments and how you can still get value from them. The Thought Process Let’s take a real-world example. This week I held the Prairie IT Pro & Dev Con event. We’ve gotten a lot of session feedback already, most of it overwhelmingly positive. But some not so much – and some to an extreme I rarely see but isn’t entirely surprising to me. So here’s the example from a person we’ll refer to as Mr. Horrible: How was the speaker? Horrible! Worst speaker ever! Did the session meet your expectations? Hard to tell, speaker ruined it. Other Comments: DO NOT bring this speaker back! He was at this conference last year and I hoped enough negative feedback would have taught you to not bring him back...obviously not...I will not return to this conference next year if this speaker is brought back. Now those are very strong words. “Worst speaker ever!” “Speaker ruined it” “I will not return to this conference next year if the speaker is brought back”. The speakers I invite to speak at my conference are not just presenters but friends and colleagues. When I see this, my initial reaction is of course very emotional: I get defensive, I get angry, I get offended. So that’s where the process kicks in. Step 1 – Take a Deep Breath Take a deep breath, calm down, and walk away from the keyboard. I didn’t do that recently during an email convo between some colleagues and it ended up in my reacting emotionally on Twitter – did I mention those colleagues follow my Twitter feed? Yes, I ate some crow. Ok, now that we’re calm, let’s move on to step 2. Step 2 – Strip off the Emotion We need to take off the emotion that people wrap their words in and identify the root issues. For instance, if I see: “I hated this session, the presenter was horrible! He spoke so fast I couldn’t make out what he was saying!” then I drop off the personal emoting (“I hated…”) and the personal attack (“the presenter was horrible”) and focus on the real issue this person had – that the speaker was talking too fast. Now we have a root cause of the displeasure. However, we’re also dealing with humans who are all very different. Before I call up the speaker to talk about his speaking pace, I need to do some other things first. Back to our Mr. Horrible example, I don’t really have much to go on. There’s no details of how the speaker “ruined” the session or why he’s the “worst speaker ever”. In this case, the next step is crucial. Step 3 – Validate the Feedback When I tell people that we really like getting feedback for the sessions, I really really mean it. Not just because we want to hear what individuals have to say but also because we want to know what the group thought. When a piece of negative feedback comes in, I validate it against the group. So with the speaker Mr. Horrible commented on, I go to the feedback and look at other people’s responses: 2 x Excellent 1 x Alright 1 x Not Great 1 x Horrible (our feedback guy) That’s interesting, it’s a bit all over the board. If we look at the comments more we find that the people who rated the speaker excellent liked the presentation style and found the content valuable. The one guy who said “Not Great” even commented that there wasn’t anything really wrong with the presentation, he just wasn’t excited about it. In that light, I can try to make a few assumptions: - Mr. Horrible didn’t like the speakers presentation style - Mr. Horrible was expecting something else that wasn’t communicated properly in the session description - Mr. Horrible, for whatever reason, just didn’t like this presenter Now if the feedback was overwhelmingly negative, there’s a different pattern – one that validates the negative feedback. Regardless, I never take something at face value. Even if I see really good feedback, I never get too happy until I see that there’s a group trend towards the positive. Step 4 – Action Plan Once I’ve validated the feedback, then I need to come up with an action plan around it. Let’s go back to the other example I gave – the one with the speaker going too fast. I went and looked at the feedback and sure enough, other people commented that the speaker had spoken too quickly. Now I can go back to the speaker and let him know so he can get better. But what if nobody else complained about it? I’d still mention it to the speaker, but obviously one person’s opinion needs to be weighed as such. When we did PrDC Winnipeg in 2011, I surveyed the attendees about the food. Everyone raved about it…except one person. Am I going to change the menu next time for that one person while everyone else loved it? Of course not. There’s a saying – A sure way to fail is to try to please everyone. Let’s look at the Mr. Horrible example. What can I communicate to the speaker with such limited information provided in the feedback from Mr. Horrible? Well looking at the groups feedback, I can make a few suggestions: - Ensure that people understand in the session description the style of the talk - Ensure that people understand the level of detail/complexity of the talk and what prerequisite knowledge they should have I’m looking at it as possibly Mr. Horrible assumed a much more advanced talk and was disappointed, while the positive feedback by people who – from their comments – suggested this was all new to them, were thrilled with the session level. Step 5 – Follow Up For some feedback, I follow up personally. Especially with negative or constructive feedback, its important to let the person know you heard them and are making changes because of their comments. Even if their comments were emotionally charged and overtly negative, it’s still important to reach out personally and professionally. When you remove the emotion, negative comments can be the best feedback you get. Also, people have bad days. We’ve all had one of “those days” where we talked more sternly than normal to someone, or got angry at something we’d normally shrug off. We have various stresses in our lives and sometimes they seep out in odd ways. I always try to give some benefit of the doubt, and re-evaluate my view of the person after they’ve responded to my communication. But, there is such a thing as garbage feedback. What Mr. Horrible wrote is garbage. It’s mean spirited. It’s hateful. It provides nothing constructive at all. And a tell-tale sign that feedback is garbage – the person didn’t leave their name even though there was a field for it. Step 6 – Delete It Feedback must be processed in its raw form, and the end products should drive improvements. But once you’ve figured out what those things are, you shouldn’t leave raw feedback lying around. They are snapshots in time that taken alone can be damaging. Also, you should never rest on past praise. In a future blog post, I’m going to talk about how we can provide great feedback that, even when its critical, can still be constructive.

  • PHP Exec command - How to pass input to a series of questions

    - by user556597
    I have a program on my linux server that asks the same series of questions each time it executes and then provides several lines of output. My goal is to automate the input and output with a php script. I know how to capture the output in an array by writing: $out = array(); exec("my/path/program",$out); But how do I handle the input? Assume the program asks 3 questions and valid answers are: left 120 n What is the easiest way using php to pass that input to the program? Can I do it somehow on the exec line? I’m not a php noob but simply have never needed to do this before. Alas, my googling is going in circles.

  • Python - Linux - Connecting to MS SQL with Windows Credentials - FreeTDS+UnixODBC + pyodbc or pymssq

    - by Keith P
    There doesn't seem to be any great instructions for setting this up. Does anyone have any good instructions? I am a linux noob so be gentle. I did see another post that is similar, but no real answer. I have a couple of problems. FreeTDS doesn't "seem" to be working. I am trying to connect and I get the following message using the "tsql" command: "Default database being set to databaseName There was a problem connecting to the server" but it doesn't mention what the problem is. The error I get when I try to connect using pyodbc is: "pyodbc.Error: ('08S01', '[08S01] [unixODBC][FreeTDS][SQL Server]Unable to connect: Adaptive Server is unavailable or does not exist (20009) (SQLDriverConnectW)')" I tried something similar with pymssql, but I ran into similar issues. I keep getting errors that I can't connect, but it doesn't tell me why.

  • Flex - Is there a way to change the "Channel Disconnected" error message?

    - by Travesty3
    I have a Flash app with a PHP backend. Whenever there is a PHP error, I get the "Channel Disconnected before an acknowledgement was received" error message. I'm getting ready to push my project to beta and I would prefer if this message said something more like "There was a PHP error, please log a bug" or something instead of a message they don't understand. Anyone know of a way for me to change this error message? BTW I'm pretty much a noob when it comes to Flash programming so please be descriptive. Using Flash Builder 4 Beta 2.

  • Microsoft Robotics Studio, simple simulation

    - by Arkapravo
    I am soon to start with Microsoft Robotics Studio. My question is to all the gurus of MSRS, Can simple simulation (as obstacle avoidance and wall following) be done without any hardware ? Does MSRS have 3-dimensional as well as 2-dimensional rendering? As of now I do not have any hardware and I am only interested in simulation, when I have the robot hardware I may try to interface it! Sorry for a silly question, I am a MSRS noob, but have previous robotics h/w and s/w experience.

    Hi All, im doing an aplication with Lucene (im a noob with it) and im facing some problems. My aplication uses the Lucene 2.4.0 library with a custom similaraty implementation (the jar is imported) In my app im calculating doqFreq and numDocs manually (im adding the values of all indexes and then i calculate a global value in order to use it on every query) and i want to use that values on a custom similarity implementation in order to calculate a new IDF. The problem is that I dont know how to use (or send) the new doqFreq and numDocs values from my app on that new similarty implementation as I dont want to change lucene´s code apart from this extra class. Any suggestions or examples? I read the docs but i dont now how to aproach this :s Thanks

  • Ajax Enabled WCF Service Javascript issue...

    - by Captain Insano
    I'm a noob working with Ajax-Enabled WCF Services... Right now I have an AJAX service which calls a different WCF service that is using wsHttpBinding. The WCF wsHttpBinding service lives in a different web app on the same IIS6 server. The AJAX javascript proxy is only created when I enable anonymous access on the app hosting the AJAX service. If I remove anonymous access, IE6 bombs with an 'Undefined' error when call the AJAX proxy. In a nut shell, my AJAX service sends a request back to IIS (same domain/app), and while on the server it sends a WCF service request for data on a different app on the same IIS server. The service returning data is setup with Windows authentication, wsHttpBinding, and security mode is set to message. Any ideas? Both apps have are using windows authentication.

  • How to use Cassandra's Map Reduce with or w/o Pig?

    - by UltimateBrent
    Can someone explain how MapReduce works with Cassandra .6? I've read through the word count example, but I don't quite follow what's happening on the Cassandra end vs. the "client" end. https://svn.apache.org/repos/asf/cassandra/trunk/contrib/word_count/ For instance, let's say I'm using Python and Pycassa, how would I load in a new map reduce function, and then call it? Does my map reduce function have to be java that's installed on the cassandra server? If so, how do I call it from Pycassa? There's also mention of Pig making this all easier, but I'm a complete Hadoop noob, so that didn't really help. Your answer can use Thrift or whatever, I just mentioned Pycassa to denote the client side. I'm just trying to understand the difference between what runs in the Cassandra cluster vs. the actual server making the requests.

    I need a light css editor with certain functions. Already downloaded and tried a few apps but still no luck, none of them fit my requirements. Actually, there is one, CssEdit (or TextMate), but unfortunately i'm a windows user... Already tried: built-in NetBeans IDE css editor (btw nice editor, the one i'm using now for css) IntelJ IDE (very good html and css editor, but using the entire ide just for this - that's crazy) ArduoCss (very buggy in win7 environment) Notepad Notepad++ (it rules, but as i said, i need something more functional for css editing) Style Master ( if i don't find anything else, probably i'll choose this one) Stylizer ( also might be my choice, but it's black interface kills me, also extremy noob-oriented, i even couldn't find a way to see the source code) Some of the features i am looking for: grouping by comments like here snippets autocomplete, if i type for instance f-s, it should recognize and expand it to "font-size" property color picker The editor must have at least the first feature that i listed above. Sorry for my poor english.

  • Pylons 1.0 AttributeError: 'module' object has no attribute 'metadata'

    - by shiki
    Python noob trying to learn Pylons. I'm using the QuickWiki tutorial (http://pylonshq.com/docs/en/1.0/tutorials/quickwiki_tutorial/) from the 1.0 documentation, but this alleged "1.0" doc seems to just be "0.9.7"; I suspect that this has something to do with the error I'm getting. When I execute "paster setup-app development.ini", I get this: (mydevenv)lucid@lucid-laptop:~/QuickWiki$ paster setup-app development.ini Traceback (most recent call last): ... edited for brevity...

  • MGTwitterEngine - Using getImageAtURL on iPhone

    - by Andrew Malchow
    Essentially, I'm working on asynchronously downloading images and adding them to specific UITableView cells (twitter profile images using MGTwitterEngine from Matt Gemmell). I've looked at general asynchronous download code and must admit, I'm still too much of a noob to understand it well enough to adapt it to my purposes. Instead, I'm attempting to use Gemmell's included getImageAtUrl method to add the images. I have it working to the point that -imageReceived: receives the images for visible cells, however, I'm stuck as to how to include them into the appropriate cells at that point. - (void)imageReceived:(UIImage *)image forRequest:(NSString *)identifier { NSLog(@"Got an image:%@",image); // What goes here? Or elsewhere? } This method is within my main view controller, I also have a custom cell controller where I'm drawing the cell content using Loren Brichter's fast scrolling code. Any help with this MGTwitterEngine method in particular, or with dynamically adding these images to my table cells would be greatly appreciated.
