• What are the steps for making domain-neutral assemblies?

  - by Mystagogue

  ...and can those steps also be applied to a 3rd party assembly (that might already be strong-named)? The context for my question should not be important, but I'll share anyway: I'm thinking of making a logger (or log-wrapper) that always knows what "log source" to target, regardless of whether the assemblies using it are in one appdomain, or spread across several appdomains. I think one way to achieve that, is to have a domain-neutral assembly with a static "LogSource" property. If that static property is set in a domain-neutral assembly, I think all appdomains will see it.

• TABINDEX not working on HyperLinks

  - by b0x0rz

  <asp:HyperLink ID="SignIn" runat="server" CssClass="SignIn" TabIndex="3">Sign In</asp:HyperLink> the problem with the above is that TABINDEX does not work. I have also a username and password TEXTBOXES and the tabindex works with them, but the hyperlink does not work. i need it also on other links, so replacing a sign in with a button is not helping me much, unless i replace all links with a button. how to figure out why the hyperlink's tabindex is not working? thnx edit ** more info ** <input name="ctl00$ctl00$GlobalPageContentPlaceHolder$SearchPageContentPlaceHolder$KeywordsTextbox" type="text" maxlength="80" id="KeywordsTextbox" class="KeywordsTextbox" /> <a id="GlobalPageContentPlaceHolder_SearchPageContentPlaceHolder_SearchLinkButton" class="SearchLinkButton" href="javascript:__doPostBack(&#39;ctl00$ctl00$GlobalPageContentPlaceHolder$SearchPageContentPlaceHolder$SearchLinkButton&#39;,&#39;&#39;)">Search Now</a> whn tab-ing it works for the input, but not for link.

• Differences between query using LINQ and IQueryable interface directly?

  - by JohnMetta

  Using Entity Framework 4, and given: ObjectSet<Thing> AllThings = Context.CreateObjectSet<Thing>; public IQueryable<Thing> ByNameA(String name) { IQueryable<Thing> query = from o in AllThings where o.Name == name select o; return query; } public IQueryable<Thing> ByNameB(String name) { return AllThings.Where((o) => o.Name == name); } Both return IQueryable< instances, and thus the query doesn't hit the server until something like ToList() is called, right? Is it purely readability that is the difference, or are the using fundamentally different technologies on the back-end?

• Where is the appropriate place to define inflector rules in CakePHP 1.3?

  - by Daniel Wright

  In CakePHP 1.2, custom inflector rules could be defined in a file app/config/inflections.php. This file was removed in CakePHP 1.3. Instead, the documentation prescribes using the Inflector::rules function to load custom inflections. There's adequate documentation of how to define the custom inflections themselves, but the documentation gives no context—where to use Inflector::rules. Should any custom inflections be defined in the bootstrap.php script? At the top of applicable corresponding controllers? Somewhere else? See also: Configuration: Inflections in the documentation Inflector::rules definition in the API documentation

• UAC on Win2k8/VIsta x64 - local "Administrator" works but domain account in Administrators group fai

  - by deltanine

  I have come across a strange problem in one of our applications on win2k8/Vista x64 with UAC enabled. It is a process which hosts the UI for our service and runs in the context of the logged on user. When logged in as a domain user who is a member of the "Administrators" group, writing to the registry under HKLM fails due to UAC with access denied. But when logged in as the local "Administrator" account (non-domain) then writing to the registry succeeds. Both accounts are adminstrators - is there a distinction between domain and non-domain accounts with UAC? What gives?

• How to explain to a client that you've gone over-budget and you'll need more money/time to deliver w

  - by General Tapioca

  My situation is that I have agreed on a per-project proposal with the client. The proposal is vague, but still names functionality in a way that can be argued as to whether it's included or not, while leaving some room for interpretation. I originally pressed as much as I could to get a per-month contract, arguing that the project is mostly non-predictable, but the client refused. Being a small company, I had to fold and signed a contract on an estimate based on my group's estimations. At this point we have reached completion on about 85% of the features (we think) but we ran out of budget. We have been working for almost two years with this client in previous contracts, and we have delivered a good product that they are happy with, so we have a good standing relationship. More info: -There has been a bit of scope-creep, but I don't think enough for me to hide behind that argument -We've been delivering partial releases about monthly. -We don't have systematic user-testing in place.

• Decorator for determining HTTP response from a view

  - by polera

  I want to create a decorator that will allow me to return a raw or "string" representation of a view if a GET parameter "raw" equals "1". The concept works, but I'm stuck on how to pass context to my renderer. Here's what I have so far: from django.shortcuts import render_to_response from django.http import HttpResponse from django.template.loader import render_to_string def raw_response(template): def wrap(view): def response(request,*args,**kwargs): if request.method == "GET": try: if request.GET['raw'] == "1": render = HttpResponse(render_to_string(template,{}),content_type="text/plain") return render except Exception: render = render_to_response(template,{}) return render return response return wrap Currently, the {} is there just as a place holder. Ultimately, I'd like to be able to pass a dict like this: @raw_response('my_template_name.html') def view_name(request): render({"x":42}) Any assistance is appreciated.

• I am not able launch JNLP aaplications using "Java Web Start"?

  - by akjain

  Up until recently, I was able to launch/open JNLP files in Firefox using Java web start. Don't know what happened all of a sudden JNLP files stopped launching, a splash screen appears saying Java Starting... and then nothing happens. Even the Java Console in the browser and javacpl.cpl applet doesn't open. Tried all possibilities: removed all older version and installed the latest JRE (java version "1.6.0_17"), still it doesn't work. Done some googling for this problem, people suggested to start javaws.exe with -viewer option but same behavior (a splash screen appears saying "Java Starting..." and then disappears) The problem is that I don't know any place (logs etc.) to look for to see what is causing the problem. I am using WinXP SP3, and some of the screenshots below shows further info about my system. I can provide any other detail if required but please help me solve this problem. Update: Although this question is bit old, Following solution fixed above issue for me (indeed this was the actual cause)

• Supervising multiple gen_servers with same module / different arguments

  - by Justin

  Hi, I have a OTP application comprising a single supervisor supervising a small number of gen_servers. A typical child specification is as follows: {my_server, {my_server, start_link, [123]}, permanent, 5000, worker, [my_server]} No problems so far. I now want to an add extra gen_server to the supervisor structure, using the same module Module/Fn as above, but different arguments, eg {my_server_2, {my_server, start_link, [123]}, permanent, 5000, worker, [my_server_2]} I thought this would work, but no: =SUPERVISOR REPORT==== 15-Apr-2010::16:50:13 === Supervisor: {local,my_sup} Context: start_error Reason: {already_started,<0.179.0>} Offender: [{pid,undefined}, {name,my_server_2}, {mfa,{my_server,start_link,[]}}, {restart_type,permanent}, {shutdown,5000}, {child_type,worker}] Do the module arguments in the second element of each child specification need to be different ? Thanks, Justin

• Git pull error: unable to create temporary sha1 filename

  - by gnus.es

  Hi everyone, I've got a small git repo setup with the only real purpose to be able to develop locally on several machines (work, home, laptop). Thus I have one branch and I commit/push once I leave a computer, pull once I sit down at the next. Has worked fine, up to now that is. Now when I pull on my 'live test' machine, I get the following: remote: Counting objects: 38, done. remote: Compressiremote: ng objects: 100% (20/20), done. remote: Total 20 (delta 17), reused 0 (delta 0) error: unable to create temporary sha1 filename .git/objects/ed: File exists fatal: failed to write object fatal: unpack-objects failed Searching around the net the only real answer I could find was the following: http://marc.info/?l=git&m=122720741928774&w=2 which basically states that this is a bogus error that's on top of the pile and thus says nothing about what really is wrong. Where do I go from here to find out what is wrong? Edit: Removed the local copy and re-cloned

• Creating your own UTI for an iOS app.

  - by Kalle

  Hello all, The app I'm developing has a custom file format for its files, and I'd like to be able to use the "Open In ..." feature of iOS which lets users e.g. email each other a file and then open it directly in the app. I've gotten as far as adding the CFBundleDocumentType stuff in the Info.plist file, but the problem is the LSItemContentTypes. From what I've read, I need to provide the actual file as a UTI, rather than just saying ".myfileextension", and I can't find a lot about how to create UTI's in a iOS app. Anyone know?

• Screening (multi)collinearity in a regression model

  - by aL3xa

  I hope that this one is not going to be "ask-and-answer" question... here goes: (multi)collinearity refers to extremely high correlations between predictors in the regression model. How to cure them... well, sometimes you don't need to "cure" collinearity, since it doesn't affect regression model itself, but interpretation of an effect of individual predictors. One way to spot collinearity is to put each predictor as a dependent variable, and other predictors as independent variables, determine R2, and if it's larger than .9 (or .95), we can consider predictor redundant. This is one "method"... what about other approaches? Some of them are time consuming, like excluding predictors from model and watching for b-coefficient changes - they should be noticeably different. Of course, we must always bare in mind specific context/goal of analysis... Sometimes, only remedy is to repeat a research, but right now, I'm interested in various ways of screening redundant predictors when (multi)collinearity occurs in a regression model.

• log4j: Change format of loggers configured in another library.

  - by Ignacio Thayer

  Using clojure, I've been able to successfully setup log4j very simply by using this log4j.properties file, and including log4j in my classpath. # BEGIN log4j.properties log4j.appender.STDOUT=org.apache.log4j.ConsoleAppender log4j.appender.STDOUT.layout=org.apache.log4j.PatternLayout log4j.appender.STDOUT.layout.ConversionPattern=%d{MMdd HHmmss SSS} %5p %c [%t] %m\n log4j.rootLogger=DEBUG, STDOUT Then after :use'ing clojure.contrib.logging, I'm able to print a statement with the desired formatting as expected like so: (info "About to print this") (debug "This is debug-level") My question is how to achieve a consistent formatting for logging statements made from loggers configured in other libraries. I thought I could find existing loggers using org.apache.log4j.LogManager.getCurrentLoggers() and change the PatternLayouts there, but I'm not able to iterate over that enumeration in clojure, as I get the following error: Dont know how to create ISeq from: java.util.Vector$1 I assume this is possible somehow, and probably very simply. How? Thanks much.

• Explorer right-click uploader for CMS?

  - by Pekka

  I'm looking for a "right-click upload" application like RightLoad - an application that can upload media files to a remote FTP server from the Windows Explorer's context menu. I want to customize the application to serve as a customized image uploading tool to a PHP-based CMS. The user would upload images and other media files to a defined FTP account (I'm also very open for other methods of transport, as long as they are supported by run-off-the-mill web hosting stacks) that they could then use in the CMS they log in to. For me to be able to do these customizations, the application would have to be Open Source - RightLoad is "only" Freeware. Alternatively, I'm open for closed-source and commercial suggestions as long as they allow "pre-packaged" server settings that can easily be deployed to the user. Does anybody know such a tool compatible with at least the most current versions of Windows (XP, Vista, 7)?

• How to deal with 'bad' decision forced on you regarding basic software for your product

  - by raticulin

  Here is my situation, our product used to support several of the major databases. Now management has decided to move all products to MaxDB (aka SapDB previously), and even if we keep supporting some of the previous dbs, all new installations are on MaxDB. I am sure MaxDB is a great db and can support huge SAP installations. But from the point of view of a software developper, its a nightmare. Every time you need to do something not trivial (write an stored procedure, some fancy trigger...) and you google for some info, you get like 0.1% of the hits you would with things like MySql, PostgreSql or MSSql. Mailing lists are nearly non existant. SAP does support it commercially but it is not clear wether we'll buy support. And the decision cannot be rolled back. The product works with MaxDB, but with lots of inefficiency on development and a lot of frustration, is there something one could do?

• Oracle database connection string PLSQL compatibility

  Hi I'm using an application called Logi info. it requires a connection string to my oracle database. the connection works fine but in order to configure the connection to recive ref cursors from the database, I apparently need to add PLSQLRSet=1 to the end of the string. when I do that I recieve an error "invalid connection string" Here is my connection string without plsqlrset=1 Data Source=SID; User Id=username; Password=password; My concern is that PLSQLRSet=1 might be .NET paramater only. Can anyone shed some light on the issue. Thanks

• Can I create support multiple database transactions on a single connection?

  - by draezal

  I have created a HyperSQL Database. I was just wondering whether I could run multiple transactions on a single connection. I didn't want to spawn a new connection for each transaction due to the overhead associated with this. Looking at some similar questions the suggestion appeared to be to create a pool of database connections and then block waiting for one to become available. This is a workable, but not desirable solution. Background Info (if this is relevant to the answer). My application will create a new thread when some request comes in. This request will require a database transaction. Then some not insignificant time later this transaction will be committed. Any advice appreciated :)

• How to assert/unit-test servers JSON response?

  - by shazax

  My current project uses JSON as data interchange format. Both Front-end and Back-end team agree upon a JSON structure before start integrating a service. At times due to un-notified changes in JSON structure by back-end team; it breaks the front-end code. Is there any external library that we could use to compare a mock JSON (fixture) with servers JSON response. Basically it should assert the whole JSON object and should throw an error if there is any violation in servers JSON format. Additional info: App is built on JQuery consuming REST JSON services.

• Debugging over-released objects, problem with NSZombie

  - by hyn

  I have a reproduceable EXC_BAD_ACCESS during NSAutoreleasePool -drain, which seems to indicate that I am over-releasing an object. So I enable NSZombie, but then the program does not crash any more. Nor do I get any info logged to the console. If I turn NSZombie off, the crash comes back. What is the meaning of this? I thought NSZombies were used to tackle exactly this kind of problem. If NSZombie won't help, is there another way to interrogate this over-released object? Also the crash is not reproduceable on Simulator, which is why I can't use Instruments with NSZombie.

• Simple XML parsing with Google Picasa API and JQuery

  - by zeedog

  I'm starting to look into Google's Picasa API for photo data, which provides you with a big XML file with info about albums and photos. I'm doing some quick and dirty tests to parse the XML file (which is saved locally to my hard drive for now) with JQuery and pull out the album id's, which are stored as "gphoto:id" tags, and display them in a div: $(document).ready(function() { $.get( 'albums.xml', function(data) { $(data).find('entry').each(function() { var albumId = $(this).children('gphoto:id').text(); $('#photos').append(albumId + '<br />'); }) }) }) I'm getting the following error in the console: jquery.js:3321 - Uncaught Syntax error, unrecognized expression: Syntax error, unrecognized expression: id This will work with other tags in the XML file (such as title, author, updated, etc.), but I'm trying to understand what's going on here. Does it have to do with the colon in "gphoto:id", somehow?

• MSSQL 2000 Stored Procedure to Split Shift Times

  - by JClaspill

  I am being asked to alter a system to include the ability to have pay differentials based on hours worked. The old method included a stored procedure (MSSQL2000 db) that did the basics, but simply knows the start and end of every shift. So, this is the information I start with: EMPLOYEE | TYPE | HOURS | INSTAMP | OUTSTAMP Dave | Hourly | 8.643055 | 2011-01-08 07:57:35.557 | 2011-01-08 16:36:10.120 And I need to turn that into something like: EMPLOYEE | TYPE | HOURS | INSTAMP | OUTSTAMP Dave | Hourly | 4.00 | 2011-01-08 08:00:00.000 | 2011-01-08 12:00:00.000 Dave | ShiftDiff1 | 4.50 | 2011-01-08 12:00:00.000 | 2011-01-08 16:30:00.000 The ShiftDiff's range from hours to certain days, to a combo of both. Should I try to make the SQL2000 SP do this or pass the info back to my ASP.NET(C#) app and let it handle it, then send back?
