• Increased kerning on website text

  - by Bradley Herman

  We're developing a site for a client right now and my boss (designer only) is once again making me increase letter-spacing on the text so that it looks 'prettier'. I am of the firm belief that this often causes eye-strain and hinders readability in body copy, but being the boss, she is of course always 'right' until I can provide her with examples showing why she's wrong (generally pretty easy). In this case, however, I can't find any articles talking about eye-strain and kerning, so I figured I'd ask what you guys think about the issue of increased letter-spacing in web text. Take a look at http://sparktoignite.com/allograft/process.php and tell me how you feel about the body copy. We're using font-embedding, so you'll only see the proper font in FF, Safari, and Chrome. Let me know what you guys think about the readability and eye-strain caused by the font. My boss currently thinks it's 100% perfect (she wanted the kerning increased further, but I talked her down luckily).

• Ideas on simulating webservices for local automated testing.

  - by novice123

  I am testing an app, which talks to different webservices over the internet. For my automated testing, I don't want to go over the network. To achieve this, I need to simulate the webservice on my machine using another app. My initial thought is to record all the requests and responses between client and webservice, and then just write a simulation app which replays these responses. The disadvantage here is that everytime the webservice protocol changes a bit, I have to modify all my recorded resposnes. so I am looking to see if there are more elegant solutions. have anyone solved a similar problem? any thoughts, suggestion are appreciated.

• Reading data from a socket

  - by Bobby

  I am having issues reading data from a socket. Supposedly, there is a server socket that is waiting for clients to connect. When I write a client to connect() to the server socket/port, it appears that I am connected. But when I try to read() data that the server is supposedly writing on the socket, the read() function hangs until the server app is stopped. Why would a read() call ever hang if the socket is connected? I believe that I am not ever really connected to the socket/port but I can't prove it, b/c the connect() call did not return an error. The read() call is not returning an error either, it is just never returning at all.

• How to host your own http-like server using ServiceHost or its analog capable to host WCF services?

  - by Ole Jak

  I use ServiceHost for hosting WCF cervices. I want to host near to my WCF services my own tcp programm (like WCF service but with out WCF) for direct sockets operations (like lien to some sort of broadcasting TCP stream) I want to use ServiceHost for somehow simplyfiing proces of creating my TCP sender\listener, to somehow control namespaces (so I would be able to let my clients to send TCP streams directly into my service using some nice URLs like www.example.com:34123/myserver/stream?id=1 or www.example.com:34123/myserver/stream?id=222 and so that I will not be bothered with Idea of 1 client for 1 socket at one time moment, BTW I realy want to keep my WCF services on the same port as my own server or what it is...) Can any body please help me with this?

• Javascript Regular expression to enforce 2 digits after decimal points

  - by Manas Saha

  I need to validate a text box where users are supposed to enter numeric values with 2 decimal places. I am validating the text in client side javascript. The validation will pass only if the number has precisely 2 decimal places, and there is at least 1 digit before the decimal point. (could be zero) the number before the decimal point can be 0, but can not be multiple zeroes. like 00 or 000 The number before the decimal point can not begin with more than 1 zero. Example of Passed validation: 0.01 0.12 111.23 1234.56 012345.67 123.00 0.00 Example of failed validation .12 1.1 0.0 00.00 1234. 1234.567 1234 00123.45 abcd.12 12a4.56 1234.5A I have tried with [0-9][.][0-9][0-9]$ But it is allowing alphabets before decimal point. like 12a4.56 Can anyone please fix the expression? thanks a lot in advance.

• What does "infinity" really mean on a connection timeout? Does it retry the connection?

  - by corgrath

  The difference between connection and read timeout, is that read specifies how long the data connection can be open until it automatically closesc, correct? A connection timeout specifies how long the socket should wait until a connection is established, correct? So if a connection timeout is set to "infinity" what does that really mean? Will it try to establish a connection and if no response is given (as on packets are lost? or port is down?) it will just idle? or will Could someone please explain the basics of network/socket timeouts? and in what situation can a client socket wait infinity?

• Too many open connections... Did I mess up something?

  - by Legend

  I am developing a plugin (for a Bittorrent client named Azureus programmed in Java) that lets me add peers into the current list from which it is downloading. Everything was working fine until yesterday when I started getting these weird errors: DEBUG::Thu Apr 15 10:45:40 CET 2010::org.gudy.azureus2.core3.peer.impl.control.PEPeerControlImpl::addPeer::795: Injected peer 90.35.126.126:33064 was not added - Too many connections DEBUG::Thu Apr 15 10:48:40 CET 2010::org.gudy.azureus2.core3.peer.impl.control.PEPeerControlImpl::addPeer::795: Injected peer 80.25.126.126:33064 was not added - Too many connections DEBUG::Thu Apr 15 10:52:40 CET 2010::org.gudy.azureus2.core3.peer.impl.control.PEPeerControlImpl::addPeer::795: Injected peer 90.35.126.126:33064 was not added - Too many connections I am thinking I messed up something with the TCP sockets. Does anyone know why this could be happening?

• noindex, follow on list views?

  - by Fabrizio

  On one of our client's website we have lot's of list views with links to detail views. (Image a blog with the posts overview and the single pages). The detail views don't change, but the list views will change when new items come up. The pages displaying the list view don't contain any other valuable content. So my question is: Does it make sense to define meta "noindex, follow" on the list view pages (and of course "index, follow" on the detail views) to prevent search engines to point to the list views when the keyword is found in the title or teaser of the list view. By the time the visitor clicks on the list view search result it might have changed and the content is not visible anymore, whereas if he goes directly to the single view he will definitly find what he was searching for? Related question: The startpage also contains mainly a list view. Is it a bad idea to have the start page not indexed? Any SEO gurus here? :) Thanks, Fabrizio.

• How to leverage Spring Integration in a real-world JMS distributed architecture?

  - by ngeek

  For the following scenario I am looking for your advices and tips on best practices: In a distributed (mainly Java-based) system with: many (different) client applications (web-app, command-line tools, REST API) a central JMS message broker (currently in favor of using ActiveMQ) multiple stand-alone processing nodes (running on multiple remote machines, computing expensive operations of different types as specified by the JMS message payload) How would one best apply the JMS support provided by the Spring Integration framework to decouple the clients from the worker nodes? When reading through the reference documentation and some very first experiments it looks like the configuration of an JMS inbound adapter inherently require to use a subscriber, which in a decoupled scenario does not exist. Small side note: communication should happen via JMS text messages (using a JSON data structure for future extensibility).

• Magento: Syncing product/category translations from "Store 1 > German Store View" to "Store 2 > German Store View"

  - by mattalexx

  For two different store Views using the same locale, it is easy to manage translations for miscellaneous text that's stored in CSV files. It's just a question of configuring the locale correctly so the correct CSV files will be used. But my client has entered a bunch of translations for products and categories into the admin by changing the scope to "Store 1 German" and setting the translations. But now he has Store 2, with a German store view. How does he keep "Store 1 German Store View" and "Store 2 German Store View" in sync?

• Question about A Sketching Website on the IPAD, Dragging and Touching

  - by pfunc

  I've been testing out the new functionality of html5 and js to create a sketching site. I've been looking into this for a possible client that wants their site to be ipad accessible, but also have drawing features on it. So i created a rough experiment where you can drag your mouse across a screen to draw lines. I went to test it on an ipad and realized this doesn't work. Why? because dragging on an ipad is reserved for actually dragging the screen around. Is there something you can do to get around this? I'm sure this could be done if made for an app, but what about just a normal website.

• How to create a test environnement on the production FTP

  - by Clement Herreman

  Hello, I'm currently working on a symfony webapp, which is already on production. To develop and add/delete/modify functionnality of the model, I work on my laptop, using symfony 'dev' environnemment. I test if everything work fine, then I pray a little and deploy it on the prod server (with all the risk of data error, like when I add new not null attributes on the model, prod server configuration special stuff, version of php/apache etc.). The problem is that I would like to setup a "staging" server, which would be a copy of the production server (same database, same configuration apache/php), so that, if the deployment goes bad, the production user stay untouched and working, only the staging server is down. But my client has only 1 FTP available. So, the question is : can I run 2 symfony project, with different models, on the same FTP ? Or is there another way to do what I want to do ? Thank you !

• building a web application in eclipse

  - by Noona

  As a concluding assignment for the technologies taught in a data management course, we have to write a web application using the technologies taught throughout the course, this mostly includes xhtml, css, JSP, servelets, JDBC, AJAX, webservices. the project will eventually be deployed using tomcat. we are given the option of choosing the technologies that we see fit. since this is my first time developing a web application I am having some uncertainties about where to start, so for example now I am writing the object classes that will be used in the database and implementing the operations that will be performed on the database, but I am not sure about how to make these operations available to a client through the website, I mean I think I have to write a servlet through which I can extract the request parameters and set the response accordingly, but I would still like a more specific overview of what I am going to do, so if someone can link me to a tutorial with an example that makes use of these technologies while illustrating the stages of the design so that I can see how all these things are linked together in a web project. thanks

• Flex 3 / ColdFusion Session Issue?

  - by dcolumbus

  Alright so this is an odd one... I have an application built in ColdFusion with a lot of the interactivity done with Flex. When a user logs in, there are session variables, as well as the client session that is evoked. When you browse to any given Flex Application, the variables are read in a used accordingly... however, on Windows (it seems XP and maybe others) for some reason session information like USER are randomly undefined... Could this be an issue with the session timing out? Even if I force a logout and log back in, it doesn't really seem to fix the issue... mind you, I cannot duplicate the bug myself, but it constantly happens on PCs.

• javascript: execute a bunch of asynchronous method with one callback

  - by Samuel Michelot

  I need to execute a bunch of asynchronous methods (client SQLite database), and call only one final callback. Of course, the ugly way is: execAll : function(callBack) { asynch1(function() { asynch2(function() { ... asynchN(function() { callBack(); }) }) }); } But I know there are better ways to do it. Intuitively I would detect when all call back has been called with a counter to call the final callback. I think this is a common design-pattern, so if someone could point me in the right direction... Thanks in advance !

• Monetary Escrow Recommendation

  - by buzzappsoftware

  We are a software development company. We need to establish a monetary escrow for one of our clients. The idea is they pay for the whole fixed bid project up front. However, the money is not released to us until agreed upon milestones have been met. This is very similar to the system Elance uses. From our side, we need to protect ourselves in the event we complete a client's project and by the time that happens they cannot pay for one reason or another. Thank you for your time. All help appreciated.

• Email form isn't sending

  - by Jonathan

  Hi I have an email form that isn't sending out an email to the recipient or a copy to the client. The form can be found at www.kelcos.co.uk/contact and the files associated with this are: /index.php /jquery.js /sendemail.php /submitform.php /thanks.php /verify.php I have used this form on other websites http://www.bowlesgreen.co.uk/contact/ and http://www.arbortectreecare.co.uk/contact/ and it works fine - the only difference is that these other sites use my usual hosting provider and for the one that won't send I'm working through the clients hosting provider, which I can only presume is what is causing the problem. I have contacted the hosting and so far we have eliminated a few things such as: 'The limitation to our systems is that the emails sent using scripts will be blocked if they are not going to or coming from an email address setup on the web hosting account. - so I am now sending the form to an a kelcos.co.uk address, but still no joy. PHP/ASP was originally disabled, but now has been activated the mail() script is enabled I would really appreciated any advise any of you could offer. Thanks

• Any tips of how to handle hierarchical trees in relational model?

  - by George

  Hello all. I have a tree structure that can be n-levels deep, without restriction. That means that each node can have another n nodes. What is the best way to retrieve a tree like that without issuing thousands of queries to the database? I looked at a few other models, like flat table model, Preorder Tree Traversal Algorithm, and so. Do you guys have any tips or suggestions of how to implement a efficient tree model? My objective in the real end is to have one or two queries that would spit the whole tree for me. With enough processing i can display the tree in dot net, but that would be in client machine, so, not much of a big deal. Thanks for the attention

• .Net framework 1.1 web application on Safari

  - by Vijay

  We have an intranet web application developed using .NET framework 1.1 The application has few validators and fired from the server side (They are not client side validators). The web application runs perfectly fine on IE and Firefox (both on Mac and Windows). However on Safari(ver 4.0.3) browser running on Mac, the application intermittently fails to do post-back while submitting the page and just reloads the page. Is this issue something to do with .Net framework 1.1 or Safari browser? Is there any way to resolve this issue? Any pointers on this would be very helpful. Thanks!

• Posting an image and textual based data to a wcf service

  - by James Hay

  I have a requirement to write a web service that allows me to post an image to a server along with some additional information about that image. I'm completely new to developing web services (normally client side dev) so I'm a little stumped as to what I need to look into and try. How do you post binary data and plain text into a servic? What RequestFormat should I use? It looks like my options are xml or json. Can I use either of these? Bit of a waffly question but I just need some direction rather than a solution as I can't seem to find much online.

• Can I export a SharePoint list to an Excel file subdivided into separate worksheets?

  - by ccornet

  We have a SharePoint 2007 deployment which will have a substantially large document library. My client wants the ability to export this library to an Excel spreadsheet, but specifically wants the ability to divide the spreadsheet into several worksheets based on a specific field. Is this possible to accomplish in WSS 3.0, through the object model or otherwise? There is a out-of-the-box Export to Spreadsheet, but it does not appear to support automated subdivision of the list items into separate worksheets. I do not know if Excel Services that come with MOSS are capable of it, but we do not have MOSS so we cannot consider it an option for now.

• WPF/.NET data access models - resource recommendations

  - by jasonk

  We're in the early design/prep phases of transferring/updating a rather large "legacy" 3 tier client-server app to a new version. We’re looking at doing WPF over Winforms as it appears to be the direction Microsoft is pushing development of the future and we’d like the maximize the life cycle/span of the apps. That said during the rewrite we’d like to make as many changes to our data access/presentation model to improve performance as much as possible up front as many. I’ve been doing some research along that vein but the vast majority of the resources I've found that discuss WPF focus only simple data tracking apps or focus on the very basics UI design/controls. The few items that even discuss data presentation are fairly elementary in depth. Are there any books/articles/recommended reading/other resources recommended for development related to large enterprise level business apps? Any “gotchas” that should/could be avoided? General advice to minimize the time underwater

• Recommendations for supporting both Oracle and SQL Server in the same ASP.NET app with NHibernate

  - by Hugo Zapata

  Our client wants to support both SQL Server and Oracle in the next project. Our experience comes from .NET/SQL Server platform. We will hire an Oracle developer, but our concern is with the DataAccess code. Will NHibernate make the DB Engine transparent for us? I don't think so, but i would like to hear from developers who have faced similar situations. I know this question is a little vague, because i don't have Oracle experience, so i don't know what issues we will find.
