• Web site aggregation with twitter widget SSL issue

  - by AB

  Hello! I'm seeking for solution how to isolate widget included by partial to main site. Issue appear when user access site with https. Ie 6,7 shows security confirmation dialog (part of website resources are not in secure zone). First of all I download twitter widget on our side, also I download all CSS and pictures. Then I patched widget JS to point onto downloaded resources. But still has not luck with security warning :( I guess the reason of this issue is AJAX request to twitter, but there is no idea how to sole it. (Just to create some kind of proxy on our side). Thank you for attention.

• zlib memory usage / performance. With 500kb of data.

  - by unixman83

  Is zLib Worth it? Are there other better suited compressors? I am using an embedded system. Frequently, I have only 3MB of RAM or less available to my application. So I am considering using zlib to compress my buffers. I am concerned about overhead however. The buffer's average size will be 30kb. This probably won't get compressed by zlib. Anyone know of a good compressor for extremely limited memory environments? However, I will experience occasional maximum buffer sizes of 700kb, with 500kb much more common. Is zlib worth it in this case? Or is the overhead too much to justify? My sole considerations for compression are RAM overhead of algorithm and performance at least as good as zlib.

• DSP - How are frequency amplitudes modified using DFT?

  - by Trap

  I'm trying to implement a DFT-based equalizer (not FFT) for the sole purpose of learning. To check if it works I took an audio signal, analyzed it and then resynthesized it again with no modifications made to the frequency spectrum. So far so good. Now I tried to silence some frequency bands, just by setting their amplitudes to zero before resynthesis, but definitely it's not the way to go. What I get is a rather distorted signal. I'm using the so-called 'standard way of calculating the DFT' which is by correlation. I first tried to modify the real part amplitudes only, then modifying both the real and imaginary part amplitudes. I also tried to convert the DFT output to polar notation, then modifying the magnitude and convert back to rectangular notation, but none of this is working. Can someone show me what I'm doing wrong? I tried to find info on this subject in the internet but couldn't find any. Thanks in advance.

• Has anyone got a simple step by step Mozilla plugin tutorial.

  - by s1mm0t

  I'm trying to create a Mozilla browser plugin for the sole purpose of detecting with javascript whether or not an application that I have written is installed. This was inspired by another stackoverflow question and answer on a similar subject. All I want really is a HelloWorld type example as what I need to write will be even simpler than that. There is a lot of information on the Mozilla website, but as a plugin noob and a C++ novice I'm experiencing information overload. I just need a step by step "this is how to create your first simple plugin". I have already written the IE equivalent by following this ATL tutorial. This is the kind of level of guide that I would ideally like to find. Please note, this is specifically about Mozilla plugins and not extensions - Googling this subject brings up a lot of information about extensions in addition to plugins.

• EJB 3 Session Bean Design for Simple CRUD

  - by sdoca

  I am writing an application that's sole purpose in life is to do CRUD operations for maintaining records in database. There are relationships between some of the tables/entities. Most examples I've seen for creating session beans deals with complex business logic/operations that interact with many entities which I don't have. Since my application is so very basic, what would be the best design for the session bean(s)? I was thinking of having one session bean per entity which had CRUD the methods defined. Then I thought of combining all of those session beans into a single session bean. And then I found this blog entry which is intriguing, but I must admit I don't understand all of it (what is a ServiceFacade?). I'm leaning towards session bean/entity class, but would like to hear more experienced opinions. Thanks.

• linux display drivers

  - by salman

  I've run into a major display problem on newly installed fedora 11, on my 6 years old pc which runs a pentium4 2.4 GHz processor, 1 gb ddr ram, intel 845 motherboard with integrated graphics card. When i open an image or play a video, my complete screen turns garbled. I simply cannot make out whats on my screen. With difficulty i have to close the image/video window and move around the folder window to clean the screen image. Is it because of my display drivers? How can i fix it? I also ran into mp3 plugins and flash issues which i was able to resovle. I'm new to linux, the sole purpose of isntalling it on my old pc was to learn linux but this display problem is frustrating me. Thanks, Salman

• Spring.NET. How actively is it being developed/supported?

  - by Bubba88

  I've made my choice for the developement components on the .NET platform: Spring.NET for IoC and NHibernate for data access. But how safe is it? I've heard here on SO (don't remember which post exactly) that Spring.NET is on its way down, cause for example the Java original version is developed by a large number of people; but (they say that) the sole person behind the .NET version is Mr. Mark Pollack. Is that so? And, if so, does it still make sense to count on Spring.NET for my production applications? if you have similar information about NHibernate, I'll appreciate it; though it seems that the latter is actively supported.

• Is there any reason to use TFS 2010 in a micro ISV?

  - by kyrisu

  Yesterday I was checking VS2010 editions here and I've noticed that with VS10 with MSDN we get TFS2010 with 1 CAL. I'm a micro ISV (basically sole developer, many clients). I just want to save time - did anyone tried it in similar scenario? Are there any features worth looking into for such a small implementation? P.S. Right now I'm using GIT with gitextension - I'm happy with it, but I would like something more integrated with project management and bug tracking so I can show it to my clients when I'm working on their projects.

• How do I know whether an application support OLE2 and which methods & attributes are exposed?

  - by Esti

  I want to call an ActiveX DLL or OLE2 object from ABAP. I already know the syntax of how to instantiate the object & execute the methods: data: my_object type ole2_object. create object my_object <ole2object>. call method of my_object <objectmethod>. But given a particular application, how do I know if this is supported, what the values/names of ole2object and objectmethod is? Transaction SOLE supplies a table of OLE Applications, among this is Excel.Application which I know can be instantiated as an OLE object, so it looks like you have to add the OLE2 app to this table first, but once again where can I read the data like CLSID & LibType from - is it published as part of the application?

• Longlasting Macport installation

  - by Werner

  Hi, I use Macports on Mac OSX to install some software. But there are somethings that I find very strange. For instance, yesterday I installed some app. and the it needed to get gcc43 and compile completely from source! It took a lot of time, although now everything works right. I understand that compilation of everything in the gentoo spirit is eomthing nice, but in the Mac case, not necessary. There are ony sole hardware variations, so it will be easier to get the binaries. I wonder if Macporst can be forced to get the binaries when available and therefore avoid these time consuming compilations. Thanks

• AnkhSVN - How to remove old URLs from list of URLs in the "Open from Subversion" dialog box

  - by user2942597

  I work for a small company and am the sole developer using AnkhSVN to version my code. For the server side I am using VisualSVN v2.5.8. The server is installed on my own machine (on a different drive). I have a few repositories that I created about two years ago that have been working fine. We recently completed an Active Directory Domain Rename (that's another story) so the FQDN of my machine changed so the domain portion is no longer the same as what it was when the server portion was installed. I managed to get AnkhSVN to connect to the repositories so everything is working again but the URL list that comes up on the "Open from Subversion" dialog box still has all the old URLs. How can I remove them? I've searched everywhere I can think of looking for this list but can't seem to find it anywhere. Any suggestions would be greatly appreciated. Chuck R.

• MySQL date query only returns one year, when multiple exist

  - by Bowman

  I'm a part-time designer/developer with a part-time photography business. I've got a database of photos with various bits of metadata attached. I want to query the database and return a list of the years that photos were taken, and the quantity of photos that were taken in that year. In short, I want a list that looks like this: 2010 (35 photos) 2009 (67 photos) 2008 (48 photos) Here's the query I'm using: SELECT YEAR(date) AS year, COUNT(filename) as quantity FROM photos WHERE visible='1' GROUP BY 'year' ORDER BY 'year' DESC Instead of churning out all the possible years (the database includes photos from 2010-2008), this is the sole result: 2010 (35 photos) I've tried a lot of different syntax but at this point I'm giving in and asking for help!

• Why is it bad practice to use links with the javascript: "protocol"?

  - by zneak

  Hello everyone, In the 1990s, there was a fashion to put Javascript code directly into <a> href attributes, like this: <a href="javascript:alert('Hello world!')">Press me!</a> And then suddenly I stopped to see it. They were all replaced by things like: <a href="#" onclick="alert('Hello world!')">Press me!</a> For a link whose sole purpose is to trigger Javascript code, and has no real href target, why is it encouraged to use the onclick property instead of the href property?

• SQL Server Service Broker Service Disappearing (Automatically Deleted)?

  - by mwigdahl

  I've implemented a messaging system over SQL Server Service Broker. It is working great, with the sole exception that every once in a while (maybe once per week per server) my initiator service just vanishes without a trace. The corresponding queue is still there, but the service is missing. Obviously this causes problems in my system. It's a simple matter to recreate the service by hand, but I'm confused as to what might cause this behavior. I understand that automatic poison message handling causes queues to be disabled, but I don't see anything that indicates services can be disabled or deleted automatically. When this happens, I usually have a large backlog of messages in multiple application queues, but nothing extreme. Total message backlog is around 200,000. Does anyone know what might be happening here?

• High quality software examples

  - by Francisco Garcia

  One of the best ways to learn about programming is reading high quality code/projects from great engineers. Which open-source projects do you think is worth looking at? I mean, that code that you can print and sit under a tree with a glass of wine and enjoy reading. If you can, also specify if the software is great to look at because its documentation, design, UML diagrams or just plain code. I believe UML is not very common within open-source projects. Is there such a thing as a project branch that polishes code and design with the sole objective to give other programmers a great example of great software?

• Why is there no Microsoft Certified Master program targetted at developers?

  - by Jason Coyne

  In the lower level certifications, developer technology is all over the place. At the highest level (Microsoft Certified Architect), the Solutions track appears to be a good fit for high level application designers and architects. MCA requires an MCM as a prerequisite. However, none of the MCM tracks are targeted towards development. Obviously to be a good architect you need to have knowledge of other technologies, servers, sql, messaging etc. But those seem like things that should be part of the course load, and not the sole focus. Are the lower tiers really as high as you can go for application focused professionals? For most developers, the SQL MCM seems to be the best fit. Are the MCM and MCA really targeted ad more administrators and not developers?

• Casting as Interface? Awesome.

  - by cam

  I was just experimenting around with one of my programs, trying to make it looks prettier and I found something interesting. I have an interface that 4 classes inherit from. I found that if I pass the Class as an object to a method like so: ClassTest classtest = new ClassTest(); DoOperation(classtest); private void DoOperation(object o) { ((InterfaceClass)o).DoThis(); } So I can pass any type of class that inherits from InterfaceClass, and it will preform the proper interface operation? This is the coolest thing I've ever found from OOP (something I've never really studied) I really thought interfaces were created for the sole purpose of organization for developers. Are there more uses for interfaces than this?

• DotNetOpenAuth I need some help please

  - by Nate Gates

  I know this has been posted before, but never really answered, I'm using the DotNetOpenAuth to try and do GoogleID login, and every time I do details = OResponse.GetExtension<ClaimsResponse>(); I always, always, always get back null, I don't get whats the point of the GoogleID if I can't get back any information, I would think at the very least I would get an email address, so I could associate it other login information in my databse. I just don't understand could really use some help, Im probably just looking at openID in the wrong way. I'm using ASP.NET and looking to use openID/Facebook as my sole means of logging in users, I really don't want to mess with membership roles, or extra junk that ASP.NET likes to add.

• Secure Webservice?

  - by cam

  I'm trying to create a secure webservice (that provides simple database data) with PHP that can be connected to through my Silverlight application. I don't know enough about PHP to be able to see another way to do this. The webservice should only be accessible through the client, and only with the proper username/password. The only two ways I can imagine to do this would be by passing the username/password hash via URL, or use a "hidden form" and do it via POST_. I'm just trying to get past this point, I'm the sole developer on this project and I'm just trying to get past this PHP webservice part so I can get back to being an application programmer :) Normally, I would learn PHP, but I'm on the clock, so I'm just looking for a point in the right direction on how to achieve this!

• Java ThreadPool for multiple identical tasks

  - by tdimmig

  I have 1 thread who sole job is to grab DatagramPackets off of a socket and stick them in a buffer. Another thread works out of that buffer, processing the DatagramPackets. I'd like to have a pool of threads working out of that buffer. I had thought to use a fixed thread pool to do this. To do so, do I need to create the pool, then submit enough runnables for execution to fill it up? I had hoped for a way to say "this is the thread/runnable that I want you to execute, this is how many I want running, GO!". Is there such a method of doing this? Is something other than a fixed thread pool better suited?

• Are there any real life uses for the Java byte primitive type?

  - by Thorbjørn Ravn Andersen

  For some inexplicable reason the byte primitive type is signed in Java. This mean that valid values are -128..127 instead of the usual 0..255 range representing 8 significant bits in a byte (without a sign bit). This mean that all byte manipulation code usually does integer calculations and end up masking out the last 8 bits. I was wondering if there is any real life scenario where the Java byte primitive type fits perfectly or if it is simply a completely useless design decision? EDIT: The sole actual use case was a single-byte placeholder for native code. In other words, not to be manipulated as a byte inside Java code.
