• How does the NY Times iPhone app do this?

  - by ArgMan

  Alright, I have an RSS feed that gets arranged in a UITableView and then the user selects a story and it loads in a UIWebView. However, I'd like to stop using the UIWebView and just use a UITextView or UILabel. This png is what I am trying to do (just display the various text aspects of a news story): http://img411.imageshack.us/img411/2449/screenshot20100315at120.png Let me start off by saying that I have tried to use the usualNSString *myText = [webView stringByEvaluatingJavaScriptFromString:@"document.documentElement.textContent"]; and assign it to a UILabel, but it doesn't work the way that I am implementing it (in webViewDidFinishLoad--is that not correct?) and I get a blank textView and normal webView. If I overlay a UITextView on top of a UIWebView on its own (that is, a webView that just loads one page), the code posted above works fine to display the text I require, but the problem arises when the RSS feed is added into the mix. Ideas and/or help, guys? I've been stuck wondering why this doesn't work as it should for a few days now. If you have a better, more efficient way of doing it then placing the code in webViewDidFinishLoad, please let me know! Does it go in my didSelectRowAtIndexPath? I'm lost here, guys. Thank you very much in advance!

• Preventing ActiveRecord save() on an instance

  - by Craig Walker

  I have an ActiveRecord model object Foo; it represents a standard database row. I want to be able to display modified versions of instances of this object. I'd like to reuse the class itself, as it already has all the hooks & aspects I'll need. (For example: I already have a view that displays the appropriate attributes). Basically I want to clone the model instance, modify some of its properties, and feed it back to the caller (view, test, etc). I do not want these attribute modifications getting back into the database. However, I do want to include the id attribute in the cloned version, as it makes dealing with the route-helpers much easier. Thus, I plan on calling ActiveRecord::Base.clone(), manually setting the ID of the cloned instance, and then making the appropriate attribute changes to the new instance. This has me worried though; one save() on the modified instance and my original data will get clobbered. So, I'm looking to lock down the new instance so that it won't hurt anything else. I'm already planning on calling freeze() (on the understanding that this prevents further modification to the object, though the documentation isn't terribly clear). However, I don't see any obvious way to prevent a save(). What would be the best approach to achieving this?

• Invoking code both before and after WebControl.Render method

  - by Dirk

  I have a set of custom ASP.NET server controls, most of which derive from CompositeControl. I want to implement a uniform look for "required" fields across all control types by wrapping each control in a specific piece of HTML/CSS markup. For example: <div class="requiredInputContainer"> ...custom control markup... </div> I'd love to abstract this behavior in such a way as to avoid having to do something ugly like this in every custom control, present and future: public class MyServerControl : TextBox, IRequirableField { public IRequirableField.IsRequired {get;set;} protected override void Render(HtmlTextWriter writer){ RequiredFieldHelper.RenderBeginTag(this, writer) //render custom control markup RequiredFieldHelper.RenderEndTag(this, writer) } } public static class RequiredFieldHelper{ public static void RenderBeginTag(IRequirableField field, HtmlTextWriter writer){ //check field.IsRequired, render based on its values } public static void RenderEndTag(IRequirableField field, HtmlTextWriter writer){ //check field.IsRequired , render based on its values } } If I was deriving all of my custom controls from the same base class, I could conceivably use Template Method to enforce the before/after behavior;but I have several base classes and I'd rather not end up with really a convoluted class hierarchy anyway. It feels like I should be able to design something more elegant (i.e. adheres to DRY and OCP) by leveraging the functional aspects of C#, but I'm drawing a blank.

• Enterprise integration of disparate systems

  - by Chris Latta

  We're about to embark on a fairly large integration effort to kill off a bunch of Access and Sql Server databases and get everything into one coherent enterprise system. There are also a number of other systems (accounting, CRM, payroll, MS Exchange) that hold critical data that we need to integrate (use for data validation in other systems), report on and otherwise expose. It is likely that some of these systems will change in the next few years, so we need to isolate our systems to be ready for change. Ideally we would be able to expose our forms in a consistent manner across as many of our our systems as possible without having to re-develop them for each system. We are currently targeting SharePoint (2007 and soon 2010), Office (2007 and soon 2010 - Word, Excel, PowerPoint and Outlook), Reporting Services, .Net console applications, .Net Windows applications, shell extensions, and with the possibility of exposing some functionality on mobile devices (BlackBerries currently, maybe iPhones later) and via our website. We're moving development to Visual Studio 2010 (from 2005) ahead of migrating to SharePoint 2010 and Office 2010. Given that most of our development is presently targeted to the .Net framework (mostly in C#) it seems logical to stick with this unless there is some compelling reason to switch frameworks/platform for some aspects. We're thinking of your standard Database-Data Integration layer-Business Objects Layer-Web Services (or REST) layer-Client Application plus doing our own client application with WPF (or something else?) forms that can also be exposed in the MS systems (SharePoint, Office, Windows). So, we don't want much, just everything :) Basically we need to isolate ourselves from database and systems changes, create an API that can be used throughout our systems and then make this functionality available in our client applications. I'm very keen to get pointers from anyone who has tips on how to pull this off. Should we look at the Enterprise Library as a place to start? Is REST with ASP.Net MVC2 a better solution than Web Services for a system like this? Will WPF deliver forms re-use or is there something better?

• When is Googling it wrong?

  - by Drahcir

  I've been going through Stack Overflow for quite a bit now and noticed certain people (usually experienced programmers) frown upon Googling (researching) certain problems. Since I myself tend to use Google quite a bit to solve certain programming related issues I found certain comments rather demoralising. Now some of you may have come here trigger happy to delete this post but I needed some clarification. I usually Google things that usually syntax related that I would have never figured out on my own. For example I once wondered how to access the properties of a class that I didn't have a direct relationship to. So after a bit of research I discovered reflection and got what I wanted. Now in another scenario is learning a new language, in my case Silverlight were it differs in certain aspects of .NET compared to say ASP.NET. A few weeks ago I had no idea how to load another Silverlight page (usercontrol) and had to Google my way to the solution which I found wasn't as simple as I had imagined. In scenario three is were I myself frown up, that is just stealing a huge chunk of code to avoid doing the work yourself, for example paging a HTML table using JavaScript, where one just copies and pastes the JavasSript code without as much as trying to understand how it works. I do admit I have done this once or twice before for trivial tasks that had very little time limit and weren't all that important but most of the time still have to throw away what I found because it took too much time to adapt it and get what I wanted out of it. In the last scenario, I sometimes have a piece of code that I would be really unhappy about, as in I find it sloppy or too overcomplicated and try to look on the Internet to see other ways to tackle the same problem, let's say filtering through a table. With the knowledge I acquire I learned new coding practices that help me work more efficiently like "Do not repeat yourself" and such. Now in your opinion when do you find it wrong to use Google (or any other researching tool) to find a solution to your problem?

• J2EE and alternatives

  - by Ilya K

  Hello, I am J2SE developer but I have rich web-background (php, perl/cgi and so on) and now I am starting new project. It will have web interface, spaghetti business logic, relational database as storage and connections to other services. I do it from the scratch. My colleagues told me to use spring, spring security and struts. I look briefly at J2EE spec and found that it covers almost all aspects of enterprise application. I asked my colleagues why do they need spring and struts, but looks like they use technologies simply because they are familiar with them and not familiar with classic J2EE stack. So, my question is: what is bad about J2EE? Why do I need spring if there are JNDI lookups? It will take a day or two to create fake InitialContext for unit-tests. And that is all: I stand with out of external tools like spring. Why do I need spring-security if there is a security built in Servlets spec? I can map any request to any servlet using web.xml, no struts.xml is needed. I can use servlet-filters instead of struts interceptors. There is RMI, so I do not need spring-remote. And so on.. Why should I bother my self with all that fancy stuff if there is J2EE? I really want to find situation when J2EE is not enough. Do you have any? Thanks!

• Guidance required: FIrst time gonna work with real high end database (size = 50GB).

  - by claws

  I got a project of designing a Database. This is going to be my first big scale project. Good thing about it is information is mostly organized & currently stored in text files. The size of this information is 50GB. There are going to be few millions of records in each Table. Its going to have around 50 tables. I need to provide a web interface for searching & browsing. I'm going to use MySQL DBMS. I've never worked with a database more than 200MB before. So, speed & performance was never a concern but I followed things like normalization & Indexes. I never used any kind of testing/benchmarking/queryOptimization/whatever because I never had to care about them. But here the purpose of creating a database is to make it quickly searchable. So, I need to consider all possible aspects in design. I was browsing archives & found: http://stackoverflow.com/questions/1981526/what-should-every-developer-know-about-databases http://stackoverflow.com/questions/621884/database-development-mistakes-made-by-app-developers I'm gonna keep the points mentioned in above answers in mind. What else should I know? What else should I keep in mind?

• Is it getting to be time for C# to support compile-time macros?

  - by Robert Rossney

  Thus far, Microsoft's C# team has resisted adding formal compile-time macro capabilities to the language. There are aspects of programming with WPF that seem (to me, at least) to be creating some compelling use cases for macros. Dependency properties, for instance. It would be so nice to just be able to do something like this: [DependencyProperty] public string Foo { get; set; } and have the body of the Foo property and the static FooProperty property be generated automatically at compile time. Or, for another example an attribute like this: [NotifyPropertyChanged] public string Foo { get; set; } that would make the currently-nonexistent preprocessor produce this: private string _Foo; public string Foo { get { return _Foo; } set { _Foo = value; OnPropertyChanged("Foo"); } } You can implement change notification with PostSharp, and really, maybe PostSharp is a better answer to the question. I really don't know. Assuming that you've thought about this more than I have, which if you've thought about it at all you probably have, what do you think? (This is clearly a community wiki question and I've marked it accordingly.)

• Object inside of array -- works in one scope but not in another?

  - by Earlz

  Ok I've been learning some of the more advanced aspects of Javascript and now trying to use this I'm stuck. Here is my code: function Data(){} function init(state){ var item; item=new Data(); item.fieldrid=17; item.description='foo'; state.push(item); }; function findInState(state,fieldrid) { for (var item in state) { alert(item.fieldrid); //prints undefined if (item.fieldrid == fieldrid) { return item; } } return null; } var s=[]; init(s); alert(s[0].fieldrid); //prints 17 (expected) alert(findInState(s,17).fieldrid); //exception here. function returns null. A running example is here at jsbin Why does this not work? I would expect the alert in findInState to yield 17 but instead it yields undefined. What am I doing wrong?

• Can a PHP object respond to an undefined method?

  - by Nathan Long

  Rails relies on some of the neat aspects of Ruby. One of those is the ability to respond to an undefined method. Consider a relationship between Dog and Owner. Owner has_many :dogs and Dog belongs_to :owner. If you go into script/console, get a dog object with fido = Dog.find(1), and look at that object, you won't see a method or attribute called Owner. What you will see is an owner_id. And if you ask for fido.owner, the object will do something like this (at least, this is how it appears to me): I'm being asked for my .owner attribute. I don't have one of those! Before I throw a NoMethodError, do I have a rule about how to deal with this? Yes, I do: I should check and see if I have an owner_id. I do! OK, then I'll do a join and return that owner object. PHP's documentation is - ahem - a bit lacking sometimes, so I wonder if anyone here knows the answer to this: Can I define similar behavior for objects in PHP? If not, do you know of a workaround for flexible model joins like these?

• In Scrum, should a team remove points from (defect) stories that don't result in a code change?

  - by CanIgtAW00tW00t

  My work uses a Scrum-like process to manage projects. I say Scrum-like, because we call it Scrum, but our project managers exclude aspects of Scrum that are inconvenient (most notably customer interaction). One of the stories in our current sprint was to correct a defect. After spending almost an entire day working on the issue, I determined the issue was the result of a permissions issue, so I didn't end up modifying any code. Our Scrum master / project manager decided that no code change equals zero points. I know that Scrum points are supposed to measure size / complexity and not time, but our Scrum master invests a lot of time in preparing graphs and statistical information from past sprints (average velocity, average points completed, etc.) I've always been of the opinion that for statistics to be meaningful in any way, the data must be as accurate as possible. All of our data is fuzzy to begin with, because, from time to time, we're encouraged by the Scrum master to "adjust" our size / complexity estimates, both increasing and decreasing them. I'd like to hear some other developers / Scrum team members thoughts on the merits of statistics based on past sprints, and also whether they think it's appropriate to "adjust" size / complexity estimates in the middle of a sprint, or the remove all points from a story all together for situations similar to what I've just described.

• Security considerations processing emails

  - by Timmy O' Tool

  I have process that will be reading emails from an account. The objective of the process is saving to a database those emails with image(s) as attachments. I will be saving sender, subject body and image path (the image will be saved on the process). I will be showing this information on a page so I would like to know all (or most of them :) ) security aspects to cover. I plan to sanitize the subject and body of the email. I can remove most of the tags, probably it would be enough keeping the <p> tag. I'm not sure if I can trust just in a sanitizer. I would like to HTML encode everything except for the <p> tag after sanitize, just in case. Any suggestion? I'm only accepting images as attachment as I said above, any security risk I have to take into account in relation to the attachment? Thanks!

• updating a column in a table only if after the update it won't be negative and identifying all updat

  - by Azeem

  Hello all, I need some help with a SQL query. Here is what I need to do. I'm lost on a few aspects as outlined below. I've four relevant tables: Table A has the price per unit for all resources. I can look up the price using a resource id. Table B has the funds available to a given user. Table C has the resource production information for a given user (including the number of units to produce everyday). Table D has the number of units ever produced by any given user (can be identified by user id and resource id) Having said that, I need to run a batch job on a nightly basis to do the following: a. for all users, identify whether they have the funds needed to produce the number of resources specified in table C and deduct the funds if they are available from table B (calculating the cost using table A). b. start the process to produce resources and after the resource production is complete, update table D using values from table C after the resource product is complete. I figured the second part can be done by using an UPDATE with a subquery. However, I'm not sure how I should go about doing part a. I can only think of using a cursor to fetch each row, examine and update. Is there a single sql statement that will help me avoid having to process each row manually? Additionally, if any rows weren't updated, the part b. SQL should not produce resources for that user. Basically, I'm attempting to modify the sql being used for this logic that currently is in a stored procedure to something that will run a lot faster (and won't process each row separately). Please let me know any ideas and thoughts. Thanks! - Azeem

• Should core application configuration be stored in the database, and if so what should be done to se

  - by Rl

  I'm writing an application around a lot of hierarchical data. Currently the hierarchy is fixed, but it's likely that new items will be added to the hierarchy in the future. (please let them be leaves) My current application and database design is fairly generic and nothing dealing with specific nodes in the hierarchy is hardcoded, with the exception of validation and lookup functions written to retrieve external data from each node's particular database. This pleases me from a design point of view, but I'm nervous at the realization that the entire application rests on a handful of records in the database. I'm also frustrated that I have to enforce certain aspects of data integrity with database triggers rather than by foreign key constraints (an example is where several different nodes in the hierarchy have their own proprietary IDs and I store them in a single column which, when coupled with the node ID can be used to locate the foreign data). I'm starting to wonder whether it may have been appropriate to simply hardcoded these known nodes into the system so that it would be more "type safe" and less generic. How does one know when something should be hardcoded, and when it should be a configuration item? Is it just a cost-benefit analysis of clarity/safety now vs less work later, or am I missing some metric I should be using to determine whether or not this is appropriate. The steps I'm taking to protect these valuable configurations are to add triggers that prevent updates/deletes. The database user that this application uses will only have the ability to manipulate data through stored procedures. What else can I do?

• Applying powershell outside IT Management.

  - by Tormod

  Hi. We have a flexible process control system by which automation engineers configure up large application comprising thousands of small logical units that are parameterized and integrated into the control flow. There are many tasks that are repetitive on the granular level, and there are a multitude of proprietary productivity tools that have been made to meet this demand. We have different business segments, and the automation engineers vary across the board in skill sets and interests. Fancy GUI and usability versus flexibility is a common discussion. At first glance, powershell seems to be a sensible platform to implement such tooling and which also would be a advantageous cross-over skill to manage the IT aspects of the system setup and deployment as a whole. This should allow the script savvy their desired flexibility (they are already a scripting crowd) and the GUI dependant could still get their desired GUI underpinned by powershell. But I can't seem to find many people/groups who have tried to use the scriptability and object passing of powershell extensively to accommodate a heterogeneous user community outside the realm of IT management. Do anybody have any tips or word of caution? Am I missing something obvious as to why this shouldn't be done? Shouldn't powershell be taking over the world? ;-)

• Tips for using Subversion and XCode in a team project

  - by FelipeUY

  Hi to all. I've been working on an Xcode (iPhone) project with three different persons. We have the project on a Subversion repository, but we still don't completely understand some aspects of the Subversion + Xcode methodology: 1) Each time someone does a commit on a single file, it may appear or not in the project of the other developers. Even though the same person that creates the new files, it adds those files to the Repository and then it commits on those files. Why does that happens? Any suggestions? 2) Each person that is involved on the project can't do a "Commit entire project" without causing a considerable headache to the rest of the developers... any idea how this should be done?. The working methodology that we are trying to implement is that only one developer (generally the leader of the project) can Commit the entire project but he must inform the rest of the team, so everybody can be prepared to receive a message asking him to discard his changes and read the new files from the repository. I need suggestions or advice on how to handle a project with multiple developers using subversion. We have read the Subversion handbook, and many other messages on StackOverflow but I still can't find any useful advice. Thanks for any tip!

• Is SharePoint a good solution for me?

  - by Pam Bullock

  My company has many branches that use the same software suite that we've written for them. We're looking at SharePoint as a way to open a dialog with them about the software - reviews, change requests (not official ones, just for us to get an idea and for them to discuss amongst themselves what would be helpful). We would also like to utilize the document repository feature and possibly the blog. SharePoint is already available to us if we'd like to use it so that's why we're looking into it. I've done a lot of research and watched a lot of starter tutorials. It seems like it has what we're looking for. For those of you that know it well: Do you think it would be a good solution for us? Do you think it would be overkill? If so, Do you have an alternative suggestion? Are there other aspects of SharePoint that I haven't discovered yet that seems like it would be helpful for what we're doing? I will continue to research online but it's always great to hear the opinion of someone experienced with the product. Thanks so much! Pam

• Does BeginReceive() get everything sent by BeginSend()?

  - by IVlad

  I'm writing a program that will have both a server side and a client side, and the client side will connect to a server hosted by the same program (but by another instance of it, and usually on another machine). So basically, I have control over both aspects of the protocol. I am using BeginReceive() and BeginSend() on both sides to send and receive data. My question is if these two statements are true: Using a call to BeginReceive() will give me the entire data that was sent by a single call to BeginSend() on the other end when the callback function is called. Using a call to BeginSend() will send the entire data I pass it to the other end, and it will all be received by a single call to BeginReceive() on the other end. The two are basically the same in fact. If the answer is no, which I'm guessing is the case based on what I've read about sockets, what is the best way to handle commands? I'm writing a game that will have commands such as PUT X Y. I was thinking of appending a special character (# for example) to the end of each command, and each time I receive data, I append it to a buffer, then parse it only after I encounter a #.

• How to ask questions to an obstructionist?

  - by Rob Wells

  This is not related to my other recently posted question about "working with a star developer". In a similar vein, how do you work with someone who will only answer the specific question that you ask. I worked with someone who, when you asked a question on a specific aspect of the system, would give you the answer just related to the specific bit you'd asked about. For example, when processing radar messages I'd ask about an aspect of message number RJ546 and he would answer just about that specific part of RJ546. He wouldn't mention anything about the other freaky parts of the message, or mention any related aspects of the other messages. Then you'd go off and work on the processing and all of a sudden all this other freakiness would pop up. What's a good technique when working with this type of person? BTW I later found out that the person who I'd come in to replace had quit because he got sick and tired of having these surprises pop up due to the lack of information provided by this person. Edit: I forgot to add that the person was deliberately obstructionist and believed that job security came from hoarded knowledge not being disseminated.

• Best strategies for reading J code

  - by estanford

  I've been using J for a few months now, and I find that reading unfamiliar code (e.g. that I didn't write myself) is one of the most challenging aspects of the language, particularly when it's in tacit. After a while, I came up with this strategy: 1) Copy the code segment into a word document 2) Take each operator from (1) and place it on a separate line, so that it reads vertically 3) Replace each operator with its verbal description in the Vocabulary page 4) Do a rough translation from J syntax into English grammar 5) Use the translation to identify conceptually related components and separate them with line breaks 6) Write a description of what each component from (5) is supposed to do, in plain English prose 7) Write a description of what the whole program is supposed to do, based on (6) 8) Write an explanation of why the code from (1) can be said to represent the design concept from (7). Although I learn a lot from this process, I find it to be rather arduous and time-consuming -- especially if someone designed their program using a concept I never encountered before. So I wonder: do other people in the J community have favorite ways to figure out obscure code? If so, what are the advantages and disadvantages of these methods?

• How to shutdown VMware Fusion virtual machine on host shutdown

  - by Nikksno

  I have a Mac mini running Mavericks server. I installed the Atmail server + webmail vm [a linux centos distribution] in VMware Fusion Professional 6 with the VMware Tools addon. It works flawlessly. I've set it to start on boot and that works very reliably. However I've been looking for a way to also safely and gracefully shut it down whenever OS X shuts down for whatever reason. The Mac is connected to a UPS and configured to perform an automatic shutdown in case the battery starts running low so that's no additional problem. Now the first thing I did was to go into Fusion's prefs and select "Power off the vm" when closing it. However I noticed that for some arcane reason closing the vm window would actually forcibly power off the vm: so then I found this post that showed me how to change the default power options and I managed to have the vm cleanly shutdown when closing its window or quitting Fusion altogether. At this point I was hoping to have solved the problem but as it turns out upon invoking system shutdown OS X doesn't wait for the vm to shutdown and terminates Fusion before it has a chance to do so. At this point I started looking for a way to automate the process of shutting down the guest os via some advanced setting but had no luck in doing so. That's when I found a command to shut the vm down: vmrun and it worked. The only thing left was to find out a way to execute this script on os x shutdown and giving it a little time to power off completely. However this turned out to be a nightmare: I spent hours looking through several ways to do this with Startup Items, rc.shutdown, cron, launchd, etc... but none of them worked the way I had configured them. I have to say that I found very limited information on using launchd for a shutdown script execution and I know it's the latest thing in the OS X world so I'm hoping someone out there among you will be able to help me out with this. I still think this is an extremely basic feature to ask for and I was really surprised to find this little documentation on so many different aspects of this problem. Is Fusion too basic of an application for this? I really hope someone can help. Thank you very much in advance.

• GPO Software Uninstall Not Taking Place

  - by burmat

  I am having some trouble with my software GPO's and can't seem to find any answers using Google. I successfully deployed software using my policy but when I delete another, the uninstallation of the software does not take place. What I did: Deployed software using a GPO, used gpupdate /force on the workstation to update, reboot, and install the software Deleted another software installation by: Right-Click All Tasks Remove 'Immediately uninstall the software from users and computers' From there, I did another gpupdate /force to try and get the GPO to refresh and uninstall the software on the workstation. This did not work. I then forced replication between my domain controllers and ran another gpupdate /force on the workstation and this did not uninstall the software. There are not error logs or indications that the uninstall is being triggered when I go into the event viewer, and I know for a fact that the policy is working in other aspects. So my questions is: Where do I look next to find the answer as to why GPO software deployments are working but un-installations are not, based off of what I have already tried? Thank you in advance. UPDATE: After using gpresult /z, there is no indication of a pending un-installation or removal of software. Under the section entitled "Software Installations", the software I am trying to uninstall is not listed. There is no other indication that the software I am trying to uninstall even exists. I also turned on RSoP logging and did (yet another) gpupdate /force to yield no blatant results. There is no indication that an uninstall event was even triggered, let alone incapability or failure. Although I am sure I marked it to uninstall in case of two events (the falling out of the scope of management, as well as the removal of the entry), I am beginning to think the entry just never triggered something that should have been triggered. UPDATE #2: After troubleshooting this (frustrating) application assignment, I have chalked it up as a fluke. I have tested with other software to make sure that the uninstall of other application assignments is actually working, so I am assuming it is something related to the package directly. There is the possibility that my problem resides in something related to what @joeqwerty linked in a comment below but because I can't go back in time, I don't think I will be able to prove it. I will probably be running a script via another GPO to guarantee the un-installation of left over package installs. For now, Evan Anderson is getting the answer because of the debugging information I was able to put to good use. Thank you to everyone that helped contribute so far!

• CPU Lockup when loading folder of bookmarks in Firefox

  - by Gary M. Mugford

  I am running Firefox 3.6 on WinXPSP3 on a duo Core machine with 4G of memory. I am also running Avast! free anti-virus and ZoneAlarm free firewall, both latest versions. Within the last month, my service provider basically forced me to upgrade to a Docsis 3.0 compliant modem (offered me a deal I couldn't turn down). At that point, I also upgraded to FF3.6. Basically, I am not unhappy with many aspects of this switchover, EXCEPT, when I now load a folder of bookmarks (anywhere from 10 to 38) I get nothing like the load times I experienced a couple of months back. It's taking minutes rather than seconds. And the first bookmark in one of the folders, GMail, rarely loads before timing out. I have used the old trick of powering off the cable modem before my day's work. This used to fix 'load-lag' in the old days. I have switched from my ISP's DNS server to Google, OpenDNS and back. And nothing seems to work currently. It's not my DNS cache. That's been flushed and secondary computers also have the same issue when loading folders. I have watched the CPU usage and loading the folder will send VSMon (ZoneAlarm) usage over 40 percent, AVastSvc (Avast!) over 30 and Firefox will then push the needle to 100. There's a brief burst by SVCHost when the others falter in devouring cycles. Then everything subsides to single digits once the last tab is loaded. The only other nominal nastiness is VSMon ALWAYS hitting 50 percent when ANY program starts downloading content from the internet. If I shutdown ZoneAlarm (and VSMon with it), the same slow loading takes place, but this time System is running 50% plus, again driving the usage to 100 per cent. I have my doubts FF3.6 vs FF3.5 is an issue, since the other computers are still running 3.5 and suffer the same issue. Those computers are on, but inactive, most of the time, being backups. Obviously, when the CPU hits 100, I can't do much of anything in FireFox OR in other programs. Video play through WMPC or VLC is extremely choppy, although it doesn't seem to affect the audio. Any ideas what I can try next? Thanks, GM

• Revolutionary brand powder packing machine price from affecting marketplace boom and put on uniform in addition to a lengthy service life

  - by user74606

  In mining in stone crushing, our machinery company's encounter becomes much more apparent. As a consequence of production capacity in between 600~800t/h of mining stone crusher, stone is mine Mobile Cone Crushing Plant Price 25~40 times, effectively solved the initially mining stone crusher operation because of low yield prices, no upkeep problems. Full chunk of mining stone crusher. Maximum particle size for crushing 1000x1200mm, an effective answer for the original side is mine stone provide, storing significant chunks of stone can not use complications in mines. Completed goods granularity is modest, only 2~15mm, an effective option for the original mine stone size, generally blocking chute production was an issue even the grinding machine. Two types of material mixed great uniformity, desulfurization of mining stone by adding weight considerably. Present quantity added is often reached 60%, effectively minimizing the cost of raw supplies. Electrical energy consumption has fallen. Dropped 1~2KWh/t tons of mining stone electrical energy consumption, annual electricity savings of one hundred,000 yuan. Efficient labor intensity of workers and also the atmosphere. Due to mine stone powder packing machine price a high degree of automation, with out human make contact with supplies, workers working circumstances enhanced significantly. Positive aspects, and along with mine for stone crushing, CS series cone Crusher has the following efficiency traits. CS series cone Crusher Chamber is divided into 3 unique designs, the user is usually chosen in accordance with the scenario on site crushing efficiency is high, uniform item size, grain shape, rolling mortar wall friction and put on uniform in addition to a extended service life of crushing cavity-. CS series cone Crusher utilizes a one of a kind dust-proof seal, sealing dependable, properly extend the service life of the lubricant replacement cycle and parts. CS series Sprial Sand washer price manufacture of important components to choose unique materials. Each and every stroke left rolling mortar wall of broken cone distances, by permitting a lot more products into the crushing cavity, as well as the formation of big discharge volume, speed of supplies by way of the crushing Chamber. This machine makes use of the principle of crushing cavity, also as unique laminated crushing, particle fragmentation, so that the completed product drastically improved the proportions of a cube, needle-shaped stones to lower particle levels extra evenly.

• In search of a good audio player for Ubuntu 9.10

  - by Joe Casadonte

  If this should be marked Community Wiki, please let me know. I'm switching from XP to Ubuntu, and I have been very disappointed with the selection of media players available. I'm primarily interested in an audio player, but integrated video and library management is OK, too. My criteria: Must be able to play audio CDs (I'm shocked how many apps this does away with, right away) Must be able to play MP3 & WAV; OGG, SHN, FLAC are all bonuses Repeat and Shuffle modes are a must FreeDB / GraceNote through a proxy is a must (if it can read a PAC file, that would be awesome) It needs to be really small, e.g. skinnable or an applet Ability to execute a playlist is a plus Gapless MP3 playback a plus I'm running Gnome, but I'm not totally adverse to a KDE app. Command-line only is also a viable option. Some that I've tried: RhythmBox - probably the best of the lot that I've tried; I don't like its mini mode (doesn't show the song being played) and I can't figure out how to get it to hit FreeDB/GraceNote through a proxy Songbird - can't play CDs, playlist management is atrocious Banshee Jajuk Maybe a couple of more. Thanks! UPDATE I tried out VLC, Amarok and Songbord (again). VLC I eventually got to work (I had some kind of bad configuration). It seemed way more involved than I was looking for out of a music player, and in general more geared to video than audio. I couldn't fathom its library management, which I think it has; maybe it doesn't, and that's why I couldn't figure it out. Amaork looked very promising but the library management was not to my liking, and the way it handled a playlist with both MP3 and WAV is inexplicable at best. I did like some aspects of the UI, but not enough to keep it. Songbird is very finicky, but I like the library management. Sort of. It kept telling me my Watch folder was invalid, even thought it clearly was accessible. Playlist management is bizarre, and the message that it was deleting source files whenever I deleted a playlist had me too worried to keep using it. Had it been able to play CDs, maybe I would have persevered. Audacious, while a bit odd at times, does seem to do what I want. If it had a library manager, I wouldn't have bothered trying any of the others. Thanks for the help, everyone!
