• Android Packaging Problem: resources.ap_ does not exist

  - by Galip

  I am trying to fix a problem in Eclipse for like 3 hours and I haven't made any progress. Tomorrow is the customer coming to look at my app, and I have no time left. This is really frustrating! This morning when I was coding and I wanted to run my app on my device Eclipse crashed all of a sudden. 'aapt.exe has stopped working' After this Eclipse wasn't starting anymore. It froze at the splash image. I looked on the internet and tried different solutions like going back to Java SE 6 update 20, changing .ini file etc. in the end reinstalling Eclipse did the job. Shortly after that the 'aapt.exe has stopped working' returned. I found a solution by changing my projects target. 1.5, 1.6, 2.2 doesn't matter, as long as it's different than the one before. Now I get the Error generating final archive: java.io.FileNotFoundException: C:\xxx\bin\resources.ap_ does not exist error. I tried clean but that doesn't work. Deleting and automatically regenarting R.java also didn't work. I ran the same code in Netbeans with the Android plugin and there it gives me the 'aapt.exe has stopped working' again :( Please guys, how can I fix this? Edit: I think I may have found the reason. These are the error lines in the console: org.xmlpull.v1.XmlPullParserException: Binary XML file line #3: <bitmap> requires a valid src attribute at android.graphics.drawable.BitmapDrawable.inflate(BitmapDrawable.java:341) at android.graphics.drawable.Drawable.createFromXmlInner(Drawable.java:779) at android.graphics.drawable.Drawable.createFromXml(Drawable.java:720) at com.android.layoutlib.bridge.ResourceHelper.getDrawable(ResourceHelper.java:150) at com.android.layoutlib.bridge.BridgeTypedArray.getDrawable(BridgeTypedArray.java:668) at android.view.View.<init>(View.java:1846) at android.view.View.<init>(View.java:1795) at android.view.ViewGroup.<init>(ViewGroup.java:282) at java.lang.reflect.Method.invoke(Unknown Source) at org.eclipse.equinox.launcher.Main.invokeFramework(Main.java:619) at org.eclipse.equinox.launcher.Main.basicRun(Main.java:574) at org.eclipse.equinox.launcher.Main.run(Main.java:1407) at org.eclipse.equinox.launcher.Main.main(Main.java:1383) [2011-01-17 16:37:20 - gegevens.xml] Unable to resolve drawable "com.android.layoutlib.utils.ResourceValue@267e33de" in attribute "background" The file it's talking about is 'bg.png'. It's a small png file which I repeat in a .xml file. <?xml version="1.0" encoding="utf-8"?> <bitmap xmlns:android="http://schemas.android.com/apk/res/android" android:src="@drawable/bg" android:tileMode="repeat" /> This file has worked from the first time without any problems. I deleted it from the drawable folder, waited for an error message, and then added it back. The red x next to the foldername got away, but still nothing different...

• Validate a string in a table in SQL Server - CLR function or T-SQL

  - by Ashish Gupta

  I need to check If a column value (string) in SQL server table starts with a small letter and can only contain '_', '-', numbers and alphabets. I know I can use a SQL server CLR function for that. However, I am trying to implement that validation using a scalar UDF and could make very little here...I can use 'NOT LIKE', but I am not sure how to make sure I validate the string irrespective of the order of characters or in other words write a pattern in SQL for this. Am I better off using a SQL CLR function? Any help will be appreciated.. Thanks in advance Thank you everyone for their comments. This morning, I chose to go CLR function way. For the purpose of what I was trying to achieve, I created one CLR function which does the validation of an input string and have that called from a SQL UDF and It works well. Just to measure the performance of t-SQL UDF using SQL CLR function vs t- SQL UDF, I created a SQL CLR function which will just check if the input string contains only small letters, it should return true else false and have that called from a UDF (IsLowerCaseCLR). After that I also created a regular t-SQL UDF(IsLowerCaseTSQL) which does the same thing using the 'NOT LIKE'. Then I created a table (Person) with columns Name(varchar) and IsValid(bit) columns and populate that with names to test. Data :- 1000 records with 'Ashish' as value for Name column 1000 records with 'ashish' as value for Name column then I ran the following :- UPDATE Person Set IsValid=1 WHERE dbo.IsLowerCaseTSQL (Name) Above updated 1000 records (with Isvalid=1) and took less than a second. I deleted all the data in the table and repopulated the same with same data. Then updated the same table using Sql CLR UDF (with Isvalid=1) and this took 3 seconds! If update happens for 5000 records, regular UDF takes 0 seconds compared to CLR UDF which takes 16 seconds! I am very less knowledgeable on t-SQL regular expression or I could have tested my actual more complex validation criteria. But I just wanted to know, even I could have written that, would that have been faster than the SQL CLR function considering the example above. Are we using SQL CLR because we can implement we can implement lot richer logic which would have been difficult otherwise If we write in regular SQL. Sorry for this long post. I just want to know from the experts. Please feel free to ask if you could not understand anything here. Thank you again for your time.

• OSX, G/AWK, Bash - "illegal statement"

  - by S1syphus

  I have a script that somebody from SO kindly provided to solve an issue I was having, However, I'm having some issues getting it to work on OSX. gawk --version GNU Awk 3.1.6 awk --version awk version 20100208 The original source is: awk -F, -vOFS=, -vc=1 ' NR == 1 { for (i=1; i<NF; i++) { if ($i != "") { g[c]=i; f[c++]=$i } } } NR>2 { for (i=1; i < c; i++) { print $1,$2, $g[i] > "output_"f[i]".csv } }' data.csv When I run the script it gives the following error: awk: syntax error at source line 12 context is print $1,$2, $g[i] > >>> "output_"f <<< [i]".csv awk: illegal statement at source line 13 From the look of it the variable of [i] isn't been amended to the output file, but I don't know why. If I change AWK to GAWK and run the original script here is the output: gawk: cmd. line:11: print $1,$2, $g[i] > "output_"f[i]".csv gawk: cmd. line:11: ^ unterminated string So I edit the relevant line to fix the unterminated string print $1,$2, $g[i] > "output_"f[i]".csv" Then it runs through fine produces no errors, but there is no output files. Any ideas? I spent the majority of last night and this morning pouring over this.

• WIX will not add HKLM registry setting during Windows 7 install

  - by Scott Boettger

  Good Morning, I have written a WiX installer that works perfectly with Windows XP but when installing to a Windows 7 box I am running into difficulty with Registry Entries. What I need to do is add a HKLM entry as well as the registry entry for the program to show in the start menu. Here is the code i am using for both types of entry: <!-- Create the registry entries for the program --> <DirectoryRef Id="TARGETDIR"> <Component Id="RegistryEntriesInst" Guid="..."> <RegistryKey Root="HKLM" Key="Software\$(var.Manufacturer)\$(var.ProductName)" Action="createAndRemoveOnUninstall"> <RegistryValue Type="string" Name="installed" Value="true" KeyPath="yes"/> </RegistryKey> </Component> <Component Id="RegistryEntriesVer" Guid="..."> <RegistryKey Root="HKLM" Key="Software\$(var.Manufacturer)\$(var.ProductName)" Action="createAndRemoveOnUninstall"> <RegistryValue Type="string" Name="version" Value="$(var.ProductVersion)" KeyPath="yes"/> </RegistryKey> </Component> </DirectoryRef> <!-- To add shortcuts to the start menu to run and uninstall the program--> <DirectoryRef Id="ApplicationProgramsFolder"> <Component Id="ApplicationShortcut" Guid="..."> <Shortcut Id="ApplicationStartMenuShortcut" Name="$(var.ProductName)" Description="..."

On a side note the registry permissions are the same on the XP and 7 computers. Thanks

• Mac OS - Built SVN from source, now Apache2 not loading sites

  - by Geuis

  This relates to another question I asked earlier today. I built SVN 1.6.2 from source. In the process, it has completely screwed up my dev environment. After I built SVN, Apache wasn't loading. It was giving me this error: Syntax error on line 117 of /private/etc/apache2/httpd.conf: Cannot load /usr/libexec /apache2/mod_dav_svn.so into server: dlopen(/usr/libexec/apache2/mod_dav_svn.so, 10): no suitable image found. Did find:\n\t/usr/libexec/apache2/mod_dav_svn.so: mach-o, but wrong architecture It appears that SVN over-wrote the old mod_dav_svn.so and I am not able to get it to build as FAT, and I can't recover whatever was originally there. I resolved this(temporarily?) by commenting out the line that was loading the mod_dav_svn.so and got Apache to start at this point. However, even though Apache is running I am now getting this error when trying to access my dev sites: Directory index forbidden by Options directive: /usr/share/tomcat6/webapps/ROOT/ I have Apache2 sitting in front of Tomcat6. I access my local dev site using the internal name "http://localthesite". I have had virtual directories set up that have worked until this SVN debacle. Tomcat is installed at /usr/local/apache-tomcat, and webapps is /usr/local/apache-tomcat/webapps. Our production servers deploy tomcat to /usr/share/tomcat6, so I have symlinks setup on my system to replicate this as well. These point back to the actual installation path. This has all been working fine as well. None of our configurations for Apache2, Tomcat, or .htaccess have changed. Over the weekend, I performed a "Repair Disk Permissions" on the system. This was before I discovered the mod_dav_svn.so problem. I have been reading up on this all morning and the most common answer is that there is an Options -Indexes set. We have this in a config file, but it was there before and when I removed it during testing, I still got the same errors from Apache. At this point, I'm assuming I either totally borked the native Apache2 installation on this Mac, or that there is a permissions error somewhere that I'm missing. The permissions error could be from the SVN installation, or from my repair process. Does anyone have any idea what could be the problem? I'm totally blocked right now and have no idea where to check next.

• Is it normal for a programmer with 2 years experience to take a long time to code simple programs?

  - by ajax81

  Hi all, I'm a relatively new programmer (18 months on the scene), and I'm finally getting to the point where I'm comfortable accepting projects and developing solutions under minimal supervision. Unfortunately, this also means that I've become acutely aware of my performance shortfalls, the most prevalent of which is the amount of time it takes me to develop, test, and submit algorithms for review. A great example of what I'm talking about occurred this week when I was tasked with developing a simple XML web service (asp.net 3.5) callable via client-side JavaScript, that accepts a single parameter and returns a dataset output to a modal window (please note this is the first time I've had to develop a web service and have had ZERO experience creating/consuming them...let alone calling them from JS client side). Keeping a long story short -- I worked on it for 4 days straight, all day each day, for a grand total of 36 hours, not including the time I spent dwelling on the problem in the shower, the morning commute, and laying awake in bed at night. I learned a great deal about web services and xml/json/javascript...but was called in for a management review to discuss the length of time it took me to develop the solution. In the meeting, I was praised for the quality of my work and was in fact told that my effort was commendable. However, they (senior leads and pm's) weren't impressed with the amount of time it took me to develop the solution and expressed that they would have liked to see the solution in roughly 1/3 of the time it took me. I guess what concerns me the most is that I've identified this pattern as common for myself. Between online videos, book research, and trial/error coding...if its something I haven't seen before, I can spend up to two weeks on a problem that seems to only take the pros in the videos moments to code up. And of course, knowing that management isn't happy with this pattern has shaken me up a bit. To sum up, I have some very specific questions I'd like to ask, and would greatly appreciate your objective professional feedback. Is my experience as a junior programmer common among new developers? Or is it possible that I'm just not cut out for the work? If you suspect that my experience is not common and that there may be an aptitude issue, do you have any suggestions/solutions that I could propose to management to help bring me up to speed? Do seasoned, professional programmers ever encounter knowledge barriers that considerably delay deliverables? When you started out in the industry, did you know how to "do it all"? If not, how long did it take you to be perceived as "proficient"? Was it a natural progression of trial and error, or was there a particular zen moment when you knew you had achieved super saiyen power level? Anyways, thanks for taking the time to read my question(s). I don't know if this is the right place to ask for professional career guidance, but I greatly appreciate your willingness to help me out. Cheers, Daniel

• when I click submit it should change the text and update the row something is wrong there

  - by Yousef Altaf

  good morning programers, I have this small code which content a news control panel and I made a submit button there to active or inactive the news row so if I click on this button it should change if it's active it will be inactive it worked but there's something wrong there when I click on item one it updates the last on the table not the first on as it should do. here is the code that I use <?php $getNewsData="select * from news"; $QgetNewsData=$db->query($getNewsData)or die($db->error); $count=mysqli_num_rows($QgetNewsData); while($newsRow = mysqli_fetch_array($QgetNewsData)) { $getActivityStatus=$newsRow['news_activity']; switch($getActivityStatus){ case 1: echo"<input style='color:red; font-weight:bold; background:none; border:0;' name='inactive' type='submit' value='?????' /><input name='inActive' type='hidden' value='".$newsRow['news_id']."'/>"; break; case 0: echo"<input style='color:green; font-weight:bold; background:none; border:0;' name='active' type='submit' value='?????' /><input name='Active' type='hidden' value='".$newsRow['news_id']."'/>"; break;} } if(isset($_POST['inactive'])){ $inActive=$_POST['inActive']; echo $inActive; $updateStatus="UPDATE news SET news_activity=0 WHERE news_id='".$inActive."'

• How to hide Amazon webstore default toolbar with Prototype?

  - by melaos

  Hi Guys, after playing around this morning, i've found that there's this default chunk of html code in the amazon webstore which will add a toolbar on top of the page. the html looks like below: <td id="wba_logo_bg"> <table class="logo" border="0" cellpadding="0" cellspacing="0" width="100%"> <tbody><tr><td align="left"></td> <td class="wba_account" style="padding: 5px;" align="right" valign="top"> <table border="0" cellpadding="0" cellspacing="0"> <form action="#" id="searchForm" method="get" name="searchForm"></form> <tbody><tr><td class="wba_account_link"> <a xmlns:xhtml="http://www.w3.org/1999/xhtml" class="myAccountNav" href="#" onclick="return false;">home</a></td> <td class="myAccountDots"></td> <td class="wba_account_link"><a class="myAccountNav" href="#" onclick="return false;">view cart</a></td> <td class="myAccountDots"></td><td class="wba_account_link"><a class="myAccountNav" href="#" onclick="return false;">my account</a></td> <td class="myAccountDots"></td><td class="wba_account_link"><a class="myAccountNav" href="#" onclick="return false;">order status</a></td> <td><img src="pageEditor_files/1_pixel.gif" hspace="7"></td> <td><input name="keyword" tabindex="1" type="text"></td> <td><img alt="Search" class="wba_search_btn" onclick="return false;" onkeyup="if (13==event.keyCode) searchForm.submit();" src="pageEditor_files/btn_search.gif" style="cursor: pointer;" tabindex="2" title="Search" hspace="3"> </td></tr></tbody> </table> </td></tr></tbody> </table> </td> and thus far i was able to use prototype to find those with the class name of wba_account_link and hide them via the codes below: function hideAmazonToolbar() { $("wba_logo_bg").hide(); }//end function but what i really want to do is preferably to hide the whole tbody instead, but with my limited prototype skills, i don't really know how to do this. can anybody point me to the right resources on how to get this done? thanks! EDIT Went higher up and apparently there's a td with an id, and solve it using prototype hide function! man, i love javascript framework :) thanks :)

• Flip clock showing time issue (animations invovled)

  - by Hwang

  I'm creating a flip clock (clock where you always see in airport), but I can't seems to get the time to show at the correct timing. After the flip, then will see the number changing. But I want it to change before it flips. Currently I'm not sure whether is the animation problem, or isit I have to do something else on the script. I've uploaded the FLA so that you could have a look on how I set up the flipping animation. http://www.mediafire.com/?nzmymjgtntz Below is the AS3 code: package { import flash.display.MovieClip; import flash.events.TimerEvent; import flash.utils.Timer; public class flipClock extends MovieClip { private var clock:clockMC=new clockMC(); //seconds private var secTop1=clock.second.top1.digit; private var secTop2=clock.second.top2.digit; private var secBot1=clock.second.bot1.digit; private var secBot2=clock.second.bot2.digit; private var seconds:Number; private var minutes:Number; private var hours:Number; private var days:Number; public function flipClock():void { decrease(); addChild(clock); } private function decrease():void { var countdownTimer:Timer=new Timer(1000); //Adding an event listener to the timer object countdownTimer.addEventListener(TimerEvent.TIMER,updateTime); //Initializing timer object countdownTimer.start(); } private function updateTime(event:TimerEvent):void { decreasTimerFunction(); updateSecond(); //updateMinute(); } private function updateSecond():void { clock.second.play(); secTop1.text=num2; secTop2.text=num1; if (num1<10) { num1="0"+num1; } if (num2<10) { num2="0"+num2; } if (num1==60) { num1=0; } if (num2==60) { num2=0; } secTop1.text=num1; secTop2.text=num2; //secBot1.text=num1; //secBot2.text=num2; } private function decreasTimerFunction():void { //Create a date object for Christmas Morning var endTime:Date=new Date(2010,4,26,0,0,0,0); //Current date object var now:Date=new Date(); // Set the difference between the two date and times in milliseconds var timeDiff:Number=endTime.getTime()-now.getTime(); seconds=Math.floor(timeDiff/1000); minutes=Math.floor(seconds/60); hours=Math.floor(minutes/60); days=Math.floor(hours/24); // Set the remainder of the division vars above hours%=24; minutes%=60; seconds%=60; } } }

• Python: Script works, but seems to deadlock after some time

  - by sberry2A

  I have the following script, which is working for the most part Link to PasteBin The script's job is to start a number of threads which in turn each start a subprocess with Popen. The output from each subprocess is as follows: 1 2 3 . . . n Done Bascially the subprocess is transferring 10M records from tables in one database to different tables in another db with a lot of data massaging/manipulation in between because of the different schemas. If the subprocess fails at any time in it's execution (bad records, duplicate primary keys, etc), or it completes successfully, it will output "Done\n". If there are no more records to select against for transfer then it will output "NO DATA\n" My intent was to create my script "tableTransfer.py" which would spawn a number of these processes, read their output, and in turn output information such as number of updates completed, time remaining, time elapsed, and number of transfers per second. I started running the process last night and checked in this morning to see it had deadlocked. There were not subprocceses running, there are still records to be updated, and the script had not exited. It was simply sitting there, no longer outputting the current information because no subprocces were running to update the total number complete which is what controls updates to the output. This is running on OS X. I am looking for three things: I would like to get rid of the possibility of this deadlock occurring so I don't need to check in on it as frequently. Is there some issue with locking? Am I doing this in a bad way (gThreading variable to control looping of spawning additional thread... etc.) I would appreciate some suggestions for improving my overall methodology. How should I handle ctrl-c exit? Right now I need to kill the process, but assume I should be able to use the signal module or other to catch the signal and kill the threads, is that right? I am not sure whether I should be pasting my entire script here, since I usually just paste snippets. Let me know if I should paste it here as well.

• user defined Copy ctor, and copy-ctors further down the chain - compiler bug ? programmers brainbug

  - by J.Colmsee

  Hi. i have a little problem, and I am not sure if it's a compiler bug, or stupidity on my side. I have this struct : struct BulletFXData { int time_next_fx_counter; int next_fx_steps; Particle particles[2];//this is the interesting one ParticleManager::ParticleId particle_id[2]; }; The member "Particle particles[2]" has a self-made kind of smart-ptr in it (resource-counted texture-class). this smart-pointer has a default constructor, that initializes to the ptr to 0 (but that is not important) I also have another struct, containing the BulletFXData struct : struct BulletFX { BulletFXData data; BulletFXRenderFunPtr render_fun_ptr; BulletFXUpdateFunPtr update_fun_ptr; BulletFXExplosionFunPtr explode_fun_ptr; BulletFXLifetimeOverFunPtr lifetime_over_fun_ptr; BulletFX( BulletFXData data, BulletFXRenderFunPtr render_fun_ptr, BulletFXUpdateFunPtr update_fun_ptr, BulletFXExplosionFunPtr explode_fun_ptr, BulletFXLifetimeOverFunPtr lifetime_over_fun_ptr) :data(data), render_fun_ptr(render_fun_ptr), update_fun_ptr(update_fun_ptr), explode_fun_ptr(explode_fun_ptr), lifetime_over_fun_ptr(lifetime_over_fun_ptr) { } /* //USER DEFINED copy-ctor. if it's defined things go crazy BulletFX(const BulletFX& rhs) :data(data),//this line of code seems to do a plain memory-copy without calling the right ctors render_fun_ptr(render_fun_ptr), update_fun_ptr(update_fun_ptr), explode_fun_ptr(explode_fun_ptr), lifetime_over_fun_ptr(lifetime_over_fun_ptr) { } */ }; If i use the user-defined copy-ctor my smart-pointer class goes crazy, and it seems that calling the CopyCtor / assignment operator aren't called as they should. So - does this all make sense ? it seems as if my own copy-ctor of struct BulletFX should do exactly what the compiler-generated would, but it seems to forget to call the right constructors down the chain. compiler bug ? me being stupid ? Sorry about the big code, some small example could have illustrated too. but often you guys ask for the real code, so well - here it is :D EDIT : more info : typedef ParticleId unsigned int; Particle has no user defined copyctor, but has a member of type : Particle { .... Resource<Texture> tex_res; ... } Resource is a smart-pointer class, and has all ctor's defined (also asignment operator) and it seems that Resource is copied bitwise. EDIT : henrik solved it... data(data) is stupid of course ! it should of course be rhs.data !!! sorry for huge amount of code, with a very little bug in it !!! (Guess you shouldn't code at 1 in the morning :D )

• Memory corruption in System.Move due to changed 8087CW mode (png + stretchblt)

  - by André Mussche

  I have strange a memory corruption problem. After many hours debugging and trying I think I found something. For example: I do a simple string assignment: sTest := 'SET LOCK_TIMEOUT '; However, the result sometimes becomes: sTest = 'SET LOCK'#0'TIMEOUT ' So, the _ gets replaced by an 0 byte. I have seen this happening once (reproducing is tricky, dependent on timing) in the System.Move function, when it uses the FPU stack (fild, fistp) for fast memory copy (in case of 9 till 32 bytes to move): ... @@SmallMove: {9..32 Byte Move} fild qword ptr [eax+ecx] {Load Last 8} fild qword ptr [eax] {Load First 8} cmp ecx, 8 jle @@Small16 fild qword ptr [eax+8] {Load Second 8} cmp ecx, 16 jle @@Small24 fild qword ptr [eax+16] {Load Third 8} fistp qword ptr [edx+16] {Save Third 8} ... Using the FPU view and 2 memory debug views (Delphi - View - Debug - CPU - Memory) I saw it going wrong... once... could not reproduce however... This morning I read something about the 8087CW mode, and yes, if this is changed into $27F I get memory corruption! Normally it is $133F: The difference between $133F and $027F is that $027F sets up the FPU for doing less precise calculations (limiting to Double in stead of Extended) and different infiniti handling (which was used for older FPU’s, but is not used any more). Okay, now I found why but not when! I changed the working of my AsmProfiler with a simple check (so all functions are checked at enter and leave): if Get8087CW = $27F then //normally $1372? if MainThreadID = GetCurrentThreadId then //only check mainthread DebugBreak; I "profiled" some units and dll's and bingo (see stack): Windows.StretchBlt(3372289943,0,0,514,345,4211154027,0,0,514,345,13369376) pngimage.TPNGObject.DrawPartialTrans(4211154027,(0, 0, 514, 345, (0, 0), (514, 345))) pngimage.TPNGObject.Draw($7FF62450,(0, 0, 514, 345, (0, 0), (514, 345))) Graphics.TCanvas.StretchDraw((0, 0, 514, 345, (0, 0), (514, 345)),$7FECF3D0) ExtCtrls.TImage.Paint Controls.TGraphicControl.WMPaint((15, 4211154027, 0, 0)) So it is happening in StretchBlt... What to do now? Is it a fault of Windows, or a bug in PNG (included in D2007)? Or is the System.Move function not failsafe?

• Calling a function that resides in the main page from a plugin?

  - by Justin Lee

  I want to call a function from within plugin, but the function is on the main page and not the plugin's .js file. EDIT I have jQuery parsing a very large XML file and building, subsequently, a large list (1.1 MB HTML file when dynamic content is copied, pasted, then saved) that has expand/collapse functionality through a plugin. The overall performance on IE is super slow and doggy, assuming since the page/DOM is so big. I am currently trying to save the collapsed content in the event.data when it is collapsed and remove it from the DOM, then bring it back when it is told to expand... the issue that I am having is that when I bring the content back, obviously the "click" and "hover" events are gone. I'm trying to re-assign them, currently doing so inside the plugin after the plugin expands the content. The issue then though is that is says the function that I declare within the .click() is not defined. Also the hover event doesn't seem to be re-assigning either.... if ($(event.data.trigger).attr('class').indexOf('collapsed') != -1 ) { // if expanding // console.log(event.data.targetContent); $(event.data.trigger).after(event.data.targetContent); $(event.data.target).hide(); /* This Line --->*/ $(event.data.target + 'a.addButton').click(addResourceToList); $(event.data.target + 'li.resource') .hover( function() { if (!($(this).attr("disabled"))) { $(this).addClass("over"); $(this).find("a").css({'display':'block'}); } }, function () { if (!($(this).attr("disabled"))) { $(this).removeClass("over"); $(this).children("a").css({'display':'none'}); } } ); $(event.data.target).css({ "height": "0px", "padding-top": "0px", "padding-bottom": "0px", "margin-top": "0px", "margin-bottom": "0px"}); $(event.data.target).show(); $(event.data.target).animate({ height: event.data.heightVal + "px", paddingTop: event.data.topPaddingVal + "px", paddingBottom: event.data.bottomPaddingVal + "px", marginTop: event.data.topMarginVal + "px", marginBottom: event.data.bottomMarginVal + "px"}, "normal");//, function(){$(this).hide();}); $(event.data.trigger).removeClass("collapsed"); $.cookies.set('jcollapserSub_' + event.data.target, 'expanded', {hoursToLive: 24 * 365}); } else if ($(event.data.trigger).attr('class').indexOf('collapsed') == -1 ) { // if collapsing $(event.data.target).animate({ height: "0px", paddingTop: "0px", paddingBottom: "0px", marginTop: "0px", marginBottom: "0px"}, "normal", function(){$(this).hide();$(this).remove();}); $(event.data.trigger).addClass("collapsed"); $.cookies.set('jcollapserSub_' + event.data.target, 'collapsed', {hoursToLive: 24 * 365}); } EDIT So, having new eyes truly makes a difference. As I was reviewing the code in this post this morning after being away over the weekend, I found where I had err'd. This: $(event.data.target + 'a.addButton').click(addResourceToList); Should be this (notice the space before a.addbutton): $(event.data.target + ' a.addButton').click(addResourceToList); Same issue with the "li.resource". So it was never pointing to the right elements... Thank you, Rene, for your help!!

• Mercurial local repository backup

  - by Ricket

  I'm a big fan of backing things up. I keep my important school essays and such in a folder of my Dropbox. I make sure that all of my photos are duplicated to an external drive. I have a home server where I keep important files mirrored across two drives inside the server (like a software RAID 1). So for my code, I have always used Subversion to back it up. I keep the trunk folder with a stable copy of my application, but then I create a branch named with my username, and inside there is my working copy. I make very few changes between commits to that branch, with the understanding that the code in there is my backup. Now I'm looking into Mercurial, and I must admit I haven't truly used it yet so I may have this all wrong. But it seems to me that you have a server-side repository, and then you clone it to a working directory in the form of a local repository. Then as you work on something, you make commits to that local repository, and when things are in a state to be shared with others, you hg push to the parent repository on the server. Between pushes of stable, tested, bug-free code, where is the backup? After doing some thinking, I've come to the conclusion that it is not meant for backup purposes and it assumes you've handled that on your own. I guess I need to keep my Mercurial local repositories in my dropbox or some other backed-up location, since my in-progress code is not pushed to the server. Is this pretty much it, or have I missed something? If you use Mercurial, how do you backup your local repositories? If you had turned on your computer this morning and your hard drive went up in flames (or, more likely, the read head went bad, or the OS corrupted itself, ...), what would be lost? If you spent the past week developing a module, writing test cases for it, documenting and commenting it, and then a virus wipes your local repository away, isn't that the only copy? So then on the flip side, do you create a remote repository for every local repository and push to it all the time? How do you find a balance? How do you ensure your code is backed up? Where is the line between using Mercurial as backup, and using a local filesystem backup utility to keep your local repositories safe?

• Linux termios VTIME not working?

  - by San Jacinto

  We've been bashing our heads off of this one all morning. We've got some serial lines setup between an embedded linux device and an Ubuntu box. Our reads are getting screwed up because our code usually returns two (sometimes more, sometimes exactly one) message reads instead of one message read per actual message sent. Here is the code that opens the serial port. InterCharTime is set to 4. void COMBaseClass::OpenPort() { cerr<< "openning port"<< port <<"\n"; struct termios newtio; this->fd = -1; int fdTemp; fdTemp = open( port, O_RDWR | O_NOCTTY); if (fdTemp < 0) { portOpen = 0; cerr<<"problem openning "<< port <<". Retrying"<<endl; usleep(1000000); return; } newtio.c_cflag = BaudRate | CS8 | CLOCAL | CREAD ;//| StopBits; newtio.c_iflag = IGNPAR; newtio.c_oflag = 0; /* set input mode (non-canonical, no echo,...) */ newtio.c_lflag = 0; newtio.c_cc[VTIME] = InterCharTime; /* inter-character timer in .1 secs */ newtio.c_cc[VMIN] = readBufferSize; /* blocking read until 1 char received */ tcflush(fdTemp, TCIFLUSH); tcsetattr(fdTemp,TCSANOW,&newtio); this->fd = fdTemp; portOpen = 1; } The other end is configured similarly for communication, and has one small section of particular iterest: while (1) { sprintf(out, "\r\nHello world %lu", ++ulCount); puts(out); WritePort((BYTE *)out, strlen(out)+1); sleep(2); } //while Now, when I run a read thread on the receiving machine, "hello world" is usually broken up over a couple messages. Here is some sample output: 1: Hello 2: world 1 3: Hello 4: world 2 5: Hello 6: world 3 where number followed by a colon is one message recieved. Can you see any error we are making? Thank you. Edit: For clarity, please view section 3.2 of this resource href="http://www.faqs.org/docs/Linux-HOWTO/Serial-Programming-HOWTO.html. To my understanding, with a VTIME of a couple seconds (meaning vtime is set anywhere between 10 and 50, trial-and-error), and a VMIN of 1, there should be no reason that the message is broken up over two separate messages.

• vertical align img

  - by JK36

  I have a div called "images" which has a width of 277px. Within that div I have 9 images in it, just stored as tags. I've got the images to float left and line up quite nicely within my div, but I would like the images to align vertically, as some are portrait and others are landscape. I know I can do this if I enclose each image in a div, but the plugin I use to launch the gallery won't recognise which image is being fired, so i need to enclose them as just within the tags. This is the code I have, if someone can help me just align the images horizontally and vertically. I don't want the images to be skewed. #images_box a { float:left; padding:9px; width: 70px; height: 70px; text-align: center; vertical-align: middle; display: table-cell; } my data <div id="images"> <a class="fancybox" rel="gallery1" href="http://farm8.staticflickr.com/7069/7060779347_fbee5aae15_b.jpg" title="morning after[explored] (mariosworld343)"> <img src="http://farm8.staticflickr.com/7069/7060779347_fbee5aae15_m.jpg" alt="" /> </a> <a class="fancybox" rel="gallery1" href="http://farm8.staticflickr.com/7234/7047458501_46a2203733_b.jpg" title="Self confined...

• 2 Days of Share &amp; Point

  - by Mark Rackley

  Groovy man… SharePoint Saturday Ozarks is back for 2010, bigger and better than before. Join us for a far out time and learn more about SharePoint in one day than you could in a year from the man… Yes! SharePoint Saturday Ozarks is back! SharePoint Saturday Ozarks is the largest SharePoint conference in Arkansas, Southern Missouri, and the very north east tip of Oklahoma. Last year we had a great turn out with 20 speakers, 5 MVPs, and attendees coming from Arkansas, Texas, Oklahoma, Missouri, Kansas, Nebraska, Indiana, Ohio, Alabama, Michigan, and Washington. Hey Man… what’s SharePoint Saturday anyway? Sounds like a conspiracy man… Not to worry, SharePoint Saturday is not an arm of the government bent on mind control or any attempt what-so-ever to bring you down man. SharePoint Saturday is grass roots effort started by Michael Lotter (http://www.sharepointsaturday.org/pages/about.aspx). It is a FREE one day event where the best SharePoint speakers gather to present their love, hatred, and frustrations of SharePoint to those lucky individuals who attend. Lessons are learned, contacts are made, prizes are won, food is eaten, assorted beverages are consumed until wee hours of the morning. SharePoint Saturday started with just a few sporadic one day events here and there. However, over the past year SharePoint Saturday has exploded and it’s hard to find a weekend where there is NOT a SharePoint Saturday event happing in some corner of the globe. There are even occasions where there are two SharePoint Saturdays on the same day! Many people are pleasantly surprised at the caliber of speakers at these SharePoint Saturday events. For the most part, these speakers are more eloquent, practiced, and practical than those speakers you find at the major multi-day conferences. These guys aren’t even paid to speak.. they do it out of love man… SharePoint Saturday Ozarks 2009 Alumni We had a star studded cast last year with many returning this year! Just check out the fun that they had… John Ferringer – Admin rockstar… I can still sense the awesomeness   SharePoint poster children Mike Watson & Laura Rogers     Lori Gowin spreading the SharePoint Love Eric Shupps is a little bit country and a little bit rock and roll       Cathy Dew, Sean McDonough, and JD Wade relaxing between gigs Actually, you can see real photos from last year’s SharePoint Saturday ozarks here:  picasaweb.google.com/mrackley/SharePointSaturdayOzarks#    What’s new for SharePoint Saturday Ozarks 2010 SharePoint Saturday Ozarks 2010 will totally blow your mind man. We’re getting the band back to together with many returning speakers and few new faces. Joel Oleson will be speaking this year, maybe he’ll grace us with his song stylings. Sadly, once again, Andrew Connell will not be able to attend SharePoint Saturday Ozarks, however he did feel the need to show his support in his own way. Prizes this year currently include books, software, a Zune HD, and much more! Wait Man… You said 2 days? I thought it was a one day event? Correct you are my herbal smelling friend… SharePoint Saturday Ozarks 2010 will spread the love an additional day this year. The first day will be all about the SharePoint love, on day 2 we will be taking a leisurely float down the Buffalo National River for those interested in a truly unique experience (no banjos allowed please).   Here are the details: WHAT 4 – 5 hour float down the Buffalo National River WHEN & WHERE Sunday June 13th. We will be leaving at 10am from the Parking Lot of: Gordon’s Motel & Canoe Rental Old Highway 7 Jasper, AR 72641 (870) 446-5252 Jasper is about 30 minutes south of Harrison, AR on Highway 7 South. You are responsible for bumming a ride to/from Gordon’s Motel, but they will be shuttling us to/from the river and providing canoes and a boxed lunch. WHAT ELSE? The float trip is dependent on the weather of course, we won’t be floating down the river in a thunderstorm, however I planned SPS Ozarks around a time of year ideal for floating. We aren’t talking class 5 rapids here, you don’t need any real skill, but you need to be okay with possibly tipping your canoe over once or twice. You can bring your own assorted beverages with you, but glass containers are not allowed on the river. I suggest a small cooler with extra snacks and drinks. Also bring clothing you can get wet in (these SharePoint people can get ornery). HOW DO I SIGN UP? When you register for SharePoint Saturday Ozarks, you will have the option to also sign up for the float trip. Seats are limited though! If you do not intend to go, please do not take someone else’s place.  The cost for the float trip will be about $35 dollars per person (which you are responsible for unless we find a sponsor). The price includes shuttle to/from river, canoe, life jackets, paddles, and boxed lunch. Far out man… how do I register??? You can register for SharePoint Saturday Ozarks by going to http://spsozarks.eventbrite.com/ We are limited to 200 people for the conference and 50 people for the float trip, so register today before we are sold out. Lodging for SharePoint Saturday Ozarks will once again take place at the Hotel Seville: Annex Suites are available for $103.20 This is So Groovy.. How can I help? I’m glad you asked! We are still looking for a few sponsors and one or two more speakers. If you are interested please let me know!  You can find out more information at http://www.sharepointsaturday.org/ozarks Hey… wait a minute…. what exactly IS SharePoint man??? Come to SharePoint Saturday Ozarks and find out!!  See you guys there!

• SQLAuthority News – Pluralsight Course Review – Practices for Software Startups – Part 1 of 2

  - by pinaldave

  This is first part of the two part series of Practices for Software Startup Pluralsight Course. The course is written by Stephen Forte (Blog | Twitter). Stephen Forte is the Chief Strategy Officer of the venture backed company, Telerik, a leading vendor of developer and team productivity tools. Stephen is also a Certified Scrum Master, Certified Scrum Professional, PMP, and also speaks regularly at industry conferences around the world. He has written several books on application and database development.  Stephen is also a board member of the Scrum Alliance. Startups – Everybodies Dream Start-up companies are an important topic right now – everyone wants to start their own business.  It is also important to remember that all companies were a start up at one point – from your corner store to the giants like Microsoft and Apple.  Research proves that not every start-up succeeds, in fact, most will fail before their first year.  There are many reasons for this, and this could be due to the fact that there are many stages to a start-up company, and stumbling at any of these stages can lead to failure.  It is important to understand what makes a start-up company succeed at all its hurdles to become successful.  It is even important to define success.  For most start-ups this would mean becoming their own independently functioning company or to be bought out for a hefty profit by a larger company.  The idea of making a hefty profit by living your dream is extremely important, and you can even think of start-ups as the new craze.  That’s why studying them is so important – they are very popular, but things have changed a lot since their inception. Starting the Startups Beginning a start-up company used to be difficult, but now facilities and information is widely available, and it is much easier.  But that means it is much easier to fail, also.  Previously to start your own company, everything was planned and organized, resources were ensured and backed up before beginning; even the idea of starting your own business was a big thing.  Now anybody can do it, and the steps are simple and outlines everywhere – you can get online software and easily outsource , cloud source, or crowdsource a lot of your material.  But without the type of planning previously required, things can often go badly. New Products – New Ideas – New World There are so many fantastic new products, but they don’t reach success all the time.  I find start-up companies very interesting, and whenever I meet someone who is interested in the subject or already starting their own company, I always ask what they are doing, their plans, goals, market, etc.  I am sorry to say that in most cases, they cannot answer my questions.  It is true that many fantastic ideas fail because of bad decisions.  These bad decisions were not made intentionally, but people were simply unaware of what they should be doing.  This will always lead to failure.  But I am happy to say that all these issues can be gone because Pluralsight is now offering a course all about start-ups by Stephen Forte.  Stephen is a start up leader.  He has successfully started many companies and most are still going strong, or have gone on to even bigger and better things. Beginning Course on Startup I have always thought start-ups are a fascinating subject, and decided to take his course, but it is three hours long.  This would be hard to fit into my busy work day all at once, so I decided to do half of his course before my daughter wakes up, and the other half after she goes to sleep.  The course is divided into six modules, so this would be easy to do.  I began the first chapter early in the morning, at 5 am.  Stephen jumped right into the middle of the subject in the very first module – designing your business plan.  The first question you will have to answer to yourself, to others, and to investors is: What is your product and when will we be able to see it?  So a very important concept is a “minimal viable product.”  This means setting goals for yourself and your product.  We all have large dreams, but your minimal viable product doesn’t have to be your final vision at the very first.  For example: Apple is a giant company, but it is still evolving.  Steve Jobs didn’t envision the iPhone 6 at the very beginning.  He had to start at the first iPhone and do his market research, and the idea evolved into the technology you see now.  So for yourself, you should decide a beginning and stop point.  Do your market research.  Determine who you want to reach, what audience you want for your product.  You can have a great idea that simply will not work in the market, do need, bottlenecks, lack of resources, or competition.  There is a lot of research that needs to be done before you even write a business plan, and Stephen covers it in the very first chapter. The Team – Unique Key to Success After jumping right into the subject in the very first module, I wondered what Stephen could have in store for me for the rest of the course.  Chapter number two is building a team.  Having a team is important regardless of what your startup is.  You can be a true visionary with endless ideas and energy, but one person can still not do everything.  It is important to decide from the very beginning if you will have cofounders, team leaders, and how many employees you’ll need.  Even more important, you’ll need to decide what kind of team you want – what personalities, skills, and type of energy you want each of your employees to bring.  Do you want to have an A+ team with a B- idea, or do you have a B- idea that needs an A+ team to sell it?  Stephen asks all the hard questions!  I was especially impressed by his insight on developing.  You have to decide if you need developers, how many, and what their skills should be. I found this insight extremely useful for everyday usage, not just for start-up companies.  I would apply this kind of information in management at any position.  An amazing team will build an amazing product – and that doesn’t matter if you’re a start-up company or a small team working for a much larger business. Customer Development – The Ultimate Obective Chapter three was about customer development. According to Stephen, there are four different steps to develop a customer base.  The first question to ask yourself is if you are envisioning a large customer base buying a few products each, or a small, dedicated base that buys a lot of your product – quantity vs. Quality.  He also discusses how to earn, retain, and get more customers.  He also says that each customer should be placed in a different role – some will be like investors, who regularly spend with you and invest their money in your business.  It is then your job to take that investment and turn it into a better product in the future.  You need to deal with their money properly – think of it is as theirs as investors, not yours as profit.  At the end of this module I felt that only Stephen could provide this kind of insight, and then he listed all the resources he took his information from.  I have never seen a group of people so passionate about their customers. It was indeed a long day for me. In tomorrow’s part 2 we will discuss rest of the three module and also will see a quick video of the Practices for Software Startup Pluralsight Course.
