  • Show div based on getDay and getHours + getMinutes

    - by Peta Reardon
    I am building a website for a radio station and want to show which presenter is currently on air. I have built a web app that contains data on the presenter: name, photo, bio and start/end times for each weekday. <div id="presenter1"> <div class="slot"> <div id="sunday-off"> - </div> <div id="monday-afternoon">12:00 - 15:59</div> <div id="tuesday-afternoon">12:00 - 15:59</div> <div id="wednesday-afternoon">12:00 - 15:59</div> <div id="thursday-afternoon">12:00 - 15:59</div> <div id="friday-afternoon">12:00 - 15:59</div> <div id="saturday-morning">06:00 - 08:59</div> </div> </div> What I would like to do is use Javascript functions getDay() and getHours() + getMinutes() to show only the presenter that is scheduled to be on air based on the times specified in the app. The main part I am having difficulty with is with determining whether this presenter falls within the current time and then showing/hiding the div as necessary. Any help or guidance on how I can acheive this would be greatly appreciated.

  • Overlapping audio in IE when I show/hide videos

    - by user1062448
    I have a thumbnail list with links to individual videos. Everything works fine in all browsers but IE. In IE, if I start a video and (without slicking pause or stop) click on the thumbnail for the next video, the audio continues playing. In other words, the audio for both videos plays at once. Any suggestions? HTML: <ul class="videoButtons"> <li><a class="vidButton" href="javascript:void(0)" id="1" ><img src="images/videoPics/vid1Thumb.jpg" /><br />video title</a></li> <li><a class="vidButton" href="javascript:void(0)" id="2" ><img src="images/videoPics/vid2Thumb.jpg" /><br />video title</a></li> <li><a class="vidButton" href="javascript:void(0)" id="3" ><img src="images/videoPics/vid3Thumb.jpg" /><br />video title</a></li> </ul> <div class="box" id="video1"> <!--flv embedded object - FLVPlayer--> </div> <div class="box" id="video2"> <!--flv embedded object - FLVPlayer1--> </div> <div class="box" id="video3"> <!--flv embedded object - FLVPlayer2--> </div> Show/Hide code: $(".vidButton").click(function() { var buttonID = $(this).attr('id'); // get ID of the button clicked var video = $('#'+'video'+buttonID); // add ID number to video $('.box').hide(); // hide all other divs video.fadeTo("slow", 1); // show video }); }); // video objects swfobject.registerObject("FLVPlayer"); swfobject.registerObject("FLVPlayer1"); swfobject.registerObject("FLVPlayer2");

  • Displaying count for current_user 'likes' on a 'question' in questions/show.html.erb view

    - by bgadoci
    I have an application that allows for users to create questions, create answers to questions, and 'like' answers of others. When a current_user lands on the /views/questions/show.html.erb page I am trying to display the total 'likes' for all answers on that question, for the current_user. In my Likes table I am collecting the question_id, site_id and the user_id and I have the appropriate associations set up between user, question, answers and likes. I think I just need to call this information the right way, which I can't seem to figure out. All of the below is taking place in the /views/questions/show.html.erb page. I have tried the following: <% div_for current_user do %> You have liked this question <%= @question.likes.count %> times <% end %> Which returns all the 'likes' for the question but not filtered by current_user You have liked this question <%= current_user.question.likes.count %> times Which gives an error of 'undefined method `question' You have liked this question <%= @question.current_user.likes.count %> times Which gives an error of 'undefined method `current_user' I have tried a couple of other things but they don't make as much sense as the above to me. What am I missing?

  • hide inputs value when input is hidden

    - by toingbou
    Hello, im using this function to hide some inputs from a form when a value selected in select tag. this is the function: function showEntry(obj,optionValue){ //hide all entry selections onchange document.getElementById("group1").style.display="none"; document.getElementById("group2").style.display="none"; if(obj.value=="group1") { document.getElementById('group1').style.display="inline"; } else if(obj.value=="group2") { document.getElementById('group2').style.display="inline"; } } and this is the form: <select class="textinput" name="function_title" onchange="showEntry(this,this.value);"> <option value=""> </option> <option value="group1" >group1</option> <option value="group2" >group2</option> </select> <span id="group1" style="display:none;"> <input class="textinput" type="text" id="input1" name="input1" value="100"/> <input class="textinput" type="text" id="input2" name="input2" value="50"/> </span> <span id="group2" style="display:none;"> <input class="textinput" type="text" id="input3" name="input3" value="60"/> <input class="textinput" type="text" id="input4" name="input4" value="45"/> </span> All i want is to hide the hidden inputs value when this group of inputs are hidden. Something like that: <input class="textinput" type="text" id="input3" name="input3" value="if(obj.value!="group2") { print(60); }"/> Is that right?

  • Millionth number in the serie 2 3 4 6 9 13 19 28 42 63 ... ?

    - by HH
    It takes about minute to achieve 3000 in my comp but I need to know the millionth number in the serie. The definition is recursive so I cannot see any shortcuts except to calculate everything before the millionth number. How can you fast calculate millionth number in the serie? Serie Def n_{i+1} = \floor{ 3/2 * n_{i} } and n_{0}=2. Interestingly, only one site list the serie according to Goolge: this one. Too slow Bash code #!/bin/bash function serie { n=$( echo "3/2*$n" | bc -l | tr '\n' ' ' | sed -e 's@\\@@g' -e 's@ @@g' ); # bc gives \ at very large numbers, sed-tr for it n=$( echo $n/1 | bc ) #DUMMY FLOOR func } n=2 nth=1 while [ true ]; #$nth -lt 500 ]; do serie $n # n gets new value in the function throught global value echo $nth $n nth=$( echo $nth + 1 | bc ) #n++ done

  • Window opened from DataGrid is placed in background

    - by 0xddr
    One column in DataGrid looks like that: <DataTemplate> <StackPanel> <Image MouseDown="OpenWindow" /> <Image MouseDown="func2"/> </StackPanel> </DataTemplate> In OpenWindow window is opened: it starts opening in foreground (in front of the window with DataGrid), but when creating UI ends it is placed behind window with DataGrid, which is not expected behavior. When I changed Image to Button and MouseDown to Click everything works as it should (opened window is placed in front of the one with DataGrid).

  • JavaScript Show/Hide as Filters to list of divs

    - by deconspray
    Looking to create Javascript that acts like a filter on a list of divs. For instance, here's the intended markup... <a href="#" onclick="">Filter Item 1</a> <a href="#" onclick="">Filter Item 2</a> <a href="#" onclick="">Filter Item 3</a> <a href="#" onclick="">Filter Item 4</a> <a href="#" onclick="">Filter Item 5</a> <div class="1">Item 1</div> <div class="1">Item 1</div> <div class="2">Item 2</div> <div class="3">Item 3</div> <div class="1">Item 1</div> <div class="4">Item 4</div> <div class="4">Item 4</div> <div class="1">Item 1</div> <div class="5">Item 5</div> I want to be able to click on the link for Item 1, and show only Item 1 divs and hide all other divs, click the link of Item 2, and show only Item 2 divs and hide all other divs and so on. I've seen several similar scripts but nothing that seemingly turns divs matching the class on/off in this manner. TIA.

What will be the code to show the child category name?

  • Can hash tables really be O(1)

    - by drawnonward
    It seems to be common knowledge that hash tables can achieve O(1) but that has never made sense to me. Can someone please explain it? A. The value is an int smaller than the size of the hash table, so the value is its own hash, so there is no hash table but if there was it would be O(1) and still be inefficient. B. You have to calculate the hash, so the order is O(n) for the size of the data being looked up. The lookup might be O(1) after you do O(n) work, but that still comes out to O(n) in my eyes. And unless you have a perfect hash or a large hash table there are probably several items per bucket so it devolves into a small linear search at some point anyway. I think hash tables are awesome, but I do not get the O(1) designation unless it is just supposed to be theoretical.

  • android app doesn't show on the emulator

    - by Anna Finela Constantino
    I made an android application using eclipse and it is working fine when I started developing my app. But then as I continue to develop the app the emulator seems to be not updating the application prior to the changes I have made on the code. So I tried deleting my avd and create a new one every time I run my app, and that seems to have worked. Now my problem is that my emulator doesn't show my app. It says "Failed to install *.apk on device 'emulator-5554': An established connection was aborted by the software in your host machine". I searched for ways to solved it but none of it seems to have worked. I tried killing the adb process (as most my searches would say) on the task manager but still my app doesn't show on the emulator. The emulator is running and all but my icon is nowhere to be found. Am I misssing out something? Is the problem connected to the first problem i had before? As I said, I started developing android app recently, so please bear with me. :) I appreciate all your help.Thanks in advance.

  • how Two elements - IMG - DIV when hover over IMG show/hide the DIV - added with hover hide/show on i

    - by Jan Fosgerau
    Im very new to the wonder that is jquery. and i just figure out how to make my img buttons show/hide with a opacity difference (as such) <script type="text/javascript"> <![CDATA[ $(".ExcommKnap").mouseover(function () { $(this).stop().fadeTo('fast', 0.5, function(){}) }); $(".ExcommKnap").mouseout(function () { $(this).stop().fadeTo('fast', 1.0, function(){}) }); ]]> </script> which is good and all. but i also need to make the button when hovered over show text just above it that is specific to that button. i made these here elements that are looped in a for each. <div style="top:10px; width:755px;text-align:right; position:absolute; "> <div id="Page-{@id}" class="headlinebox"> <xsl:value-of select="@nodeName"/> </div> </div> <a href="{umbraco.library:NiceUrl(@id)}"> <img class="ExcommKnap" src="{$media/data[@alias='umbracoFile']}" /> </a> i need to make the individual text appear when hovered over its button. hence i have the id="page-{@id}" looped out along and need to get this place in the jquery code i presume. so when i hover over a img class="ExcommKnap" it makes the correct text visible. But i need the div id="page-{id}" to be invisible to begin with on pageload and then visible when its button is being hovered over. can anyone help ?

  • Setting height of a DIV to correspond with location of anchor inside said DIV

    - by filip
    Core issue : http://jsfiddle.net/pipip/P46Xg/ I have a div container with a few paragraphs of text, and inside one of these paragraphs is the following anchor <a id="stop" /> The container is set to overflow:hidden Is it possible with javascript / JQuery to set the height of the container so that the bottom of the container stops exactly at or below the anchor? Added Depth & Background : http://jsfiddle.net/pipip/yj9dB/ This would be used for a modified JQuery Slider. Where someone using a CMS could type [readmore] anywhere into the Content field, which would be replaced by the above anchor via PHP. This way they would be easily able to control where the Read More break appears within the container. In the associated example I am hard-coding the height to 75px, although what I want is for the height to be dependent on the location of the anchor id="stop" in the text. Thanks. If this is an awful way to go about it, I'm all ears!

  • Sort vector<int>(n) in O(n) time using O(m) space?

    - by Adam
    I have a vector<unsigned int> vec of size n. Each element in vec is in the range [0, m], no duplicates, and I want to sort vec. Is it possible to do better than O(n log n) time if you're allowed to use O(m) space? In the average case m is much larger than n, in the worst case m == n. Ideally I want something O(n). I get the feeling that there's a bucket sort-ish way to do this: unsigned int aux[m]; aux[vec[i]] = i; Somehow extract the permutation and permute vec. I'm stuck on how to do 3. In my application m is on the order of 16k. However this sort is in the inner loops and accounts for a significant portion of my runtime.

  • modalpopupextender.Show() wont fire

    - by Peter Lea
    I'm pretty new to developing for the web so bare with me. I have a company page with multiple locations and emails etc at each of these addresses. The idea is to have a single modalpopup to edit each type of data (one for email, one for urls, one for addresses etc). I link the modalpopupextender to a hiddenbutton and then call an edit function from various places where I can populate some hiddenfields and textboxes in the panel before showing it. The code executes but it just wont show the damn popup, I just see a flash and can't figure out if its my panel, my css or something I don't understand about ajax and postbacks etc. Things i've tried after reading various threads: Disable smart navigation in web.config Move ToolKitScriptManager up to master page and use proxy in content set hiddenbutton to use style="display:none" tried links etc instead of hidden button Heres my code CSS .modalBackground { position: absolute; z-index: 100; top: 0px; left: 0px; background-color: #000; filter: alpha(opacity=60); -moz-opacity: 0.6; opacity: 0.6; } .modalPopup { background-color: #FFD; border-width: 3px; border-style: solid; border-color: gray; padding: 3px;} Asp/html <ajaxToolkit:ModalPopupExtender runat="server" ID="mpe_email" BackgroundCssClass="modalBackground" PopupControlID="modal_email" CancelControlID="btn_cancel_email" TargetControlID="fake_btn_email" /> <asp:Button ID="fake_btn_email" runat="server" Text="email" style="display:none;" /> <asp:panel id="modal_email" runat="server" class="modalPopup" Width="500px" Height="500px"> <asp:HiddenField ID="hf_modal_email_location_id" runat="server" Value="" /> <asp:HiddenField ID="hf_modal_email_contact_id" runat="server" Value="" /> <asp:HiddenField ID="hf_modal_email_comms_id" runat="server" Value="" /> <table width="100%"> <tr> <td> <asp:Label ID="lbl_mpe_email_title" runat="server" Text="Edit Email Address" /> </td> </tr> <tr> <td> <table width="100%"> <tr> <td width="40px"><img src="../images/email.png" height="30px" width="30px"/></td> <td> <table width="100px"> <tr> <td><span>Quick Ref: <asp:TextBox ID="txb_mpe_email_qref" runat="server" Text="" /></span></td> </tr> <tr> <td><span>Email Address: <asp:TextBox ID="txb_mpe_email_address_full" runat="server" Text="" /></span></td> </tr> </table> </td> </tr> </table> </td> </tr> <tr> <td width="40px" align="left"><asp:Button ID="btn_cancel_email" runat="server" Text="Cancel"/></td> <td align="right"><asp:Button ID="btn_save_email" runat="server" Text="Save" OnCommand="save_modal_email" /></td> </tr> <tr> <td colspan="2" align="right"><asp:Label ID="lbl_mpe_email_err" runat="server" Text="" /></td> </tr> </table> c# public void oloc_ocon_email_edit(object sender, RepeaterCommandEventArgs e) { switch (e.CommandName) { case "edit": hf_modal_email_location_id.Value = ((HiddenField)e.Item.FindControl("hf_oloc_ocon_emails_location_id")).Value; hf_modal_email_contact_id.Value = ((HiddenField)e.Item.FindControl("hf_oloc_ocon_emails_contact_id")).Value; hf_modal_email_comms_id.Value = ((HiddenField)e.Item.FindControl("hf_oloc_ocon_emails_comms_id")).Value; lbl_mpe_email_title.Text = "Edit Email Address"; txb_mpe_email_qref.Text = ((HiddenField)e.Item.FindControl("hf_oloc_ocon_emails_qref")).Value; txb_mpe_email_address_full.Text = ((HiddenField)e.Item.FindControl("hf_oloc_ocon_emails_email_full")).Value; lbl_mpe_email_err.Text = ""; mpe_email.Show(); break; case "new": hf_modal_email_location_id.Value = ((HiddenField)e.Item.FindControl("hf_oloc_ocon_emails_location_id_p")).Value; hf_modal_email_contact_id.Value = ((HiddenField)e.Item.FindControl("hf_oloc_ocon_emails_contact_id_p")).Value; hf_modal_email_comms_id.Value = "0"; lbl_mpe_email_title.Text = "New Email Address"; txb_mpe_email_qref.Text = ""; txb_mpe_email_address_full.Text = ""; lbl_mpe_email_err.Text = ""; mpe_email.Show(); break; } } Stuff makes so much more sense in a desktop environment, I hope someone can point me in the right direction.

  • XBRL US Conference Highlights

    - by john.orourke(at)oracle.com
    Back in early November I had an opportunity to attend the XBRL US National Conference in Philadelphia.  At the event, XBRL US announced that Oracle had joined the initiative, so I had a chance to participate in a press conference and attend a number of sessions.  Oracle joined XBRL US so we can stay ahead of the standard and leverage it in our products, and to help drive awareness with customers and improve adoption of XBRL. There were roughly 250 attendees at the event, about half of which were vendors and consultants and the rest financial reporting staff from corporate filers.  Event sponsors included Ernst & Young, SWIFT and Fujitsu.  There were also a number of XBRL technology and service providers exhibiting at the conference.  On Monday Nov. 8th, the XBRL US Steering Committee meetings and Annual Members meeting and reception were held.  At the Annual Members meeting the big news was that current XBRL US President, Mark Bolgiano, is moving to a new position at Howard Hughes Medical Center.  Campbell Pryde, who had led the Taxonomy Development for XBRL US, is taking over as XBRL US President. Other items that were highlighted at the members meeting included: The US GAAP XBRL taxonomy is being used by over 1500 SEC filers and has now been handed over to the FASB to maintain and enhance 16 filer training events were held in 2010 XBRL Global Magazine was launched Corporate Actions proposal was submitted to the SEC with SWIFT in May XBRL Labs for iPhone, XBRL US Consistency Suite launched ISO 2022 Corporate Actions Alignment with XBRL achieved The XBRL Credit Rating taxonomy was accepted Tuesday Nov. 9th included Keynotes, General Sessions, Innovation Workshop for Governments and Securities Professionals, and an Opening Reception.  General sessions included: Lessons Learned from the SEC's rollout of XBRL.  More than 18,000 errors were identified in reviews of filings between June 2009 and September 2010.  Most of these related to negative values being used where they shouldn't have.  Also, the SEC feels there are too many taxonomy extensions being created - mostly in the Cash Flow Statements.  They emphasize using existing elements in the US GAAP taxonomy and advise filers not to  create extensions to improve the visual formatting of XBRL filings. Investors and XBRL - Setting the Standard for Data Quality.  In this panel discussion, the key learning was that CFA's, academics and the financial community are not using XBRL as expected.  The issues raised include the  accuracy and completeness of filings, number of taxonomy extensions, and limited number of tools available to help analyze XBRL data.  Another big issue that was raised is the lack of historic results in XBRL - most analysts need 10 quarters of historic data.  On the positive side, XBRL has the potential to eliminate re-keying of data and errors here and can improve analytic capabilities for financial analysts once more historic data is available and more companies are providing detailed tagging of their filings. A US Roadmap for XBRL Financial Reporting.  This was a panel discussion featuring Jeff Neumann(SEC), Campbell Pryde(XBRL US), and Louis Matherne(FASB).  Key points included the fact that XBRL is currently used by 1500 companies, with 8000 more companies coming in 2011.  XBRL for Mutual Fund Reporting will start in 2011 for 8000 funds, and a Credit Rating Taxonomy has now been submitted for review.  The XBRL tagging/filing process is improving each quarter - more education is helping here.  The FASB is looking at extensions to date, and potential additions to US GAAP taxonomy, while the SEC is evaluating filings for accuracy, consistency in tagging, and tools for analyzing data.  The big news is that the FASB 2011 US GAAP Taxonomy has been completed and reviewed by SEC.  The 2011 US GAAP Taxonomy supports new FASB accounting standards issued since 2009, has new taxonomy elements for certain industries (i.e airlines) and the elimination of 500 concepts.  (meaning they can't be used going forward but are still supported for historical comparison)  The 2011 US GAAP Taxonomy will be available for usage with Q2 2011 SEC filings.  More information about this can be found on the FASB web site.  http://www.fasb.org/home Accounting Firms and XBRL.  This session covered the Role of Audit Firms, which includes awareness and education, validation of XBRL filings, and in-house transition planning.  The main advice provided was that organizations should document XBRL mapping process, perform peer comparisons, and risk assessments on a regular basis. Wednesday Nov. 10th included more Keynotes, General Sessions on Corporate Actions, and XBRL Essentials Workshop Training for corporate filers.  The XBRL Essentials Training included: Getting Started Once you Have the Basics Detailed Footnote Tagging and Handling Tables Quality Control and Trust in the XBRL Process Bringing XBRL In-House:  What are the Options, What should you consider? The US GAAP Financial Reporting Taxonomy - Overview of the 2011 release The XBRL Essentials Training was well-attended with about 80 people.  This included a good overview of the SEC's XBRL mandate, limited liability issue, tagging levels, recommended planning process, internal vs. outsourced approach, and how to manage service providers.  I learned a lot from the session on detailed tagging.  This is the requirement that kicks in during a company's second year of XBRL filing with the SEC and applies to financial statements, footnotes and disclosures (it does not apply to MD&A, executive communications and other information).  The review of the Linkbase model, or dimensional table structure, was very interesting and can be complex to understand.  The key takeaway here is that using dimensional tables in XBRL filings can help limit the number of taxonomy extensions that are required.  The slides from this session are posted on the XBRL US web site. (http://xbrl.us/events/Pages/archive.aspx) For me, the main summary points and takeaways from the XBRL US conference are: XBRL for financial reporting has turned the corner and gone mainstream - with 1500 companies currently using it and 8000 more coming in 2011 The expected value is not being achieved by filers or consumers of XBRL data - this will improve when more companies are filing in XBRL, more history is available, and more software tools are available for analysis (hmm, sounds like an opportunity for Oracle) XBRL is becoming the global standard for all business communications beyond just the financials - i.e. adoption for mutual funds, corporate actions and others planned for the future If you would like to learn more about XBRL and the various training programs, services and software tools that are available check out the XBRL US web site and even better - become a member.  Here's a link:  http://xbrl.us/Pages/default.aspx

  • SOA Implementation Challenges

    Why do companies think that if they put up a web service that they are doing Service-Oriented Architecture (SOA)? Unfortunately, the IT and business world love to run on the latest hype or buzz words of which very few even understand the meaning. One of the largest issues companies have today as they consider going down the path of SOA, is the lack of knowledge regarding the architectural style and the over usage of the term SOA. So how do we solve this issue?I am sure most of you are thinking by now that you know what SOA is because you developed a few web services.  Isn’t that SOA, right? No, that is not SOA, but instead Just Another Web Service (JAWS). For us to better understand what SOA is let’s look at a few definitions.Douglas K. Bary defines service-oriented architecture as a collection of services. These services are enabled to communicate with each other in order to pass data or coordinating some activity with other services.If you look at this definition closely you will notice that Bary states that services communicate with each other. Let us compare this statement with my first statement regarding companies that claim to be doing SOA when they have just a collection of web services. In order for these web services to for an SOA application they need to be interdependent on one another forming some sort of architectural hierarchy. Just because a company has a few web services does not mean that they are all interconnected.SearchSOA from TechTarget.com states that SOA defines how two computing entities work collectively to enable one entity to perform a unit of work on behalf of another. Once again, just because a company has a few web services does not guarantee that they are even working together let alone if they are performing work for each other.SearchSOA also points out service interactions should be self-contained and loosely-coupled so that all interactions operate independent of each other.Of all the definitions regarding SOA Thomas Erl’s seems to shed the most light on this concept. He states that “SOA establishes an architectural model that aims to enhance the efficiency, agility, and productivity of an enterprise by positioning services as the primary means through which solution logic is represented in support of the realization of the strategic goals associated with service-oriented computing.” (Erl, 2011) Once again this definition proves that a collection of web services does not mean that a company is doing SOA. However, it does mean that a company has a collection of web services, and that is it.In order for a company to start to go down the path of SOA, they must take  a hard look at their existing business process while abstracting away any technology so that they can define what is they really want to accomplish. Once a company has done this, they can begin to factor out common sub business process like credit card process, user authentication or system notifications in to small components that can be built independent of each other and then reassembled to form new and dynamic services that are loosely coupled and agile in that they can change as a business grows.Another key pitfall of companies doing SOA is the fact that they let vendors drive their architecture. Why do companies do this? Vendors’ do not hold your company’s success as their top priority; in fact they hold their own success as their top priority by selling you as much stuff as you are willing to buy. In my experience companies tend to strive for the maximum amount of benefits with a minimal amount of cost. Does anyone else see any conflicts between this and the driving force behind vendors.Mike Kavis recommends in an article written in CIO.com that companies need to figure out what they need before they talk to a vendor or at least have some idea of what they need. It is important to thoroughly evaluate each vendor and watch them perform a live demo of their system so that you as the company fully understand what kind of product or service the vendor is actually offering. In addition, do research on each vendor that you are considering, check out blog posts, online reviews, and any information you can find on the vendor through various search engines.Finally he recommends companies to verify any recommendations supplied by a vendor. From personal experience this is very important. I can remember when the company I worked for purchased a $200,000 add-on to their phone system that never actually worked as it was intended. In fact, just after my departure from the company started the process of attempting to get their money back from the vendor. This potentially could have been avoided if the company had done the research before selecting this vendor to ensure that their product and vendor would live up to their claims. I know that some SOA vendor offer free training regarding SOA because they know that there are a lot of misconceptions about the topic. Superficially this is a great thing for companies to take part in especially if the company is starting to implement SOA architecture and are still unsure about some topics or are looking for some guidance regarding the topic. However beware that some companies will focus on their product line only regarding the training. As an example, InfoWorld.com claims that companies providing deep seminars disguised as training, focusing more about ESBs and SOA governance technology, and less on how to approach and solve the architectural issues of the attendees.In short, it is important to remember that we as software professionals are responsible for guiding a business’s technology sections should be well informed and fully understand any new concepts that may be considered for implementation. As I have demonstrated already a company that has a few web services does not mean that they are doing SOA.  Additionally, we must not let the new buzz word of the day drive our technology, but instead our technology decisions should be driven from research and proven experience. Finally, it is important to rely on vendors when necessary, however, always take what they say with a grain of salt while cross checking any claims that they may make because we have to live with the aftermath of a system after the vendors are gone.   References: Barry, D.

  • Why are bugs responsible for big deficiencies in functionality given such low priority?

    - by keepitsimpleengineer
    Well, first of all, change is inevitable and mostly good. Furthermore attempts at simplifying the User Interface such as Gnome 3, Unity to make Linux more inclusive hold much promise, even though they adversely affect my style of working. Additionally, though now retired, I have worked with computers for 47 years, and though I do nothing serious for others now, I still do heavy duty things. 10.04 LTS is my big workstation, and I had three 10.10 systems for Mythtv, and one of which is further adapted for video & related. The Mythtv were 10.10 because of a dormant bug regarding installing to 10.04. My work habits consistently use dual monitors and compiz cube and 3D windows with the computing horsepower to support them. The dual monitors with separate X screens has been not been functional since 11.04, and cube/3D windows not functional in Unity, and with diminished functionality Gnome. There is a bug filed (after upgrade to 12.04 amd64 Gnome Classic not properly draw second screen) I have mitigated the situation some by switching to Xubuntu and eschewing Unity. The question that comes to mind is why this bug is not given more attention in that it nearly cuts functionality in half for more competent workstations. Sample workspace... Please know that I appreciate all the hard work, dedication require to pull off something as big as Ubuntu et al.

  • Is a big name computer science degree worth the cost?

    - by Serplat
    I'm currently in High School and trying to look into what I want to do after I graduate. I know that I will be going to college, and that I want a degree in Computer Science, however, I'm not entirely sure where I want to go (I haven't started the application process yet). I already have built up a decent amount of experience in programming (over the summers I have been hired to program at a local university), and I'm pretty capable of teaching myself most of the material I've come across through either books or web documentation. I'm interested in whether it is worth it to get a degree from a major, big-name computer science university for $50,000 each year, as opposed to going to a local state school for only $20,000. For my Bachelor's degree alone, this would be $120,000 more than the state school. I've also heard that where you get your Bachelor's doesn't matter much if you plan to get a Master's degree. Many people recommend going somewhere like a state school for your Bachelor's, and then try to get into a more major school for your Master's. Has anybody found any truth in this? Basically, is going to a big name computer science school for a Bachelor's degree really worth the added expense?
