SQL Split function that handles string with delimeter appearing between text qualifiers?

- by Ron

There are several SQL split functions, from loop driven, to using xml commands, and even using a numbers table. I haven't found one that supports text qualifiers. Using the example string below, I would like to split on ",", but not when it appears between double or single quotes. Example data: [email protected], "Sally \"Heat\" Jones" <[email protected]>, "Mark Jones" <[email protected]>, "Stone, Ron" <[email protected]> Should return a table: [email protected] "Sally \"Heat\" Jones" <[email protected]> "Mark Jones" <[email protected]> "Stone, Ron" <[email protected]> I know this is a complex query/function, but any suggestions or any guidance would be mucho appreciated.

Ubuntu 12.04 LTS: Error message "Failed to execute child process"

- by Ron

I am an Ubuntu-newbie and just started working with Ubuntu (version 12.04 LTS) a couple of days ago. I wanted to add a launcher icon to desktop for launching an application I previously installed. Up to now I can only launch it by typing setsid matlab -desktop into my terminal. Now there is the following problem with the execution via the desktop icon: Whenever I click the desktop icon, I get the following error message: "Failed to execute child process" I would like to add a screenshot, but unfortunately as a new user, I am not allowed to... In the main menu from where I added the icon via drag'n'drop to desktop there is also a permission to execute the .desktop file. I also tried to look for advice on the error message "Failed to execute child process..." but could not find anything useful. Now does anybody have an idea what I am missing? Sorry if this is a stupid question ;) ...but as I just said: I just started with Ubuntu... Thanks to everybody in advance for their help! :) And let me know if you should need any more information... Regards, Ron

Show Notes: Getting Past the Cloud Hype

- by Bob Rhubart

This week’s ArchBeat podcast features an unvarnished bit of conversation culled from a recent virtual meet-up. These meet-ups are informal conversations among architects, many of who have participated in previous ArchBeat programs. There’s no prearranged topic, so the participants talk about whatever is on their minds. The most recent meet-up included Oracle ACE Director Ran Batra, director of cloud computing product development with AT&T, and Daniel Templeton, principal product manager for Oracle Grid Engine, and the man behind Dan T’s GridBlog. The conversation took place at the end of the year – and the end of the decade – a time when most tech publications feature their predictions for the coming year. I wanted a different spin on that theme, so I asked Ron and Dan to talk about the technologies about which they weren’t all that optimistic. I found that ten-minute chunk of conversation particularly interesting, so that’s what you’re going to hear this week. Listen Get Social If you have questions or comment for Ron and/or Daniel you can connect via the following: Ron Batra Blog | Twitter | LinkedIn | Oracle Mix | Oracle ACE Profile Daniel Templeton Blog | Twitter | LinkedIn Coming Up Oracle ACE Director Debra Lilley talks about her role in the UKOUG’s development group and that group’s collaboration with Oracle on Oracle Fusion Applications.

problems adding an App Engine app to a Google Apps domains

- by Ron

We have been adding domains to our app without any issues for past couple months, following these instructions https://developers.google.com/appengine/articles/domains Since yesterday we have not been able to, when clicking Activate this service we get this error message "An error occurred while trying to install this application. Please try again later." We have tried this also with older domains and with different apps and getting the same error, so the problem seems to be more widespread, not isolated to particular domains / apps. Does anyone know how to solve? Thanks Ron

Disk Activity Alert Windows SBS 2003 on Dell PowerEdge 830 with Raid

- by Ron Whites

Background: I have a Dell PowerEdge 830 Server running Windows SB Server 2003. It has 4gbs of RAM and a ATA CERC SATA 6CH controller with 3 160gb drives in a Raid 5 configuration. The Problem I am seeing Admin ---"Disk Activity Alert on Server" emails These often occur when disk backups, de-frag or high disk usage is going on. Generally the server isn't over stressed. The Disk Alert emails say in part ... The following disk has low idle time, which may cause slow response time when reading or writing files to the disk. Disk: 0 C: F: D: Review the Disk Transfers/sec and % Idle Time counters for the PhysicalDisk performance object. If the Disk Transfers/sec counter is consistently below 150 while the % Idle Time counter remains very low (close to 0), there may be a problem with the disk driver or hardware. The Questions I have: With what utility can I review the Disk Transfers/sec and Idle Time? It appears there is no utility for that on the server! I think I may need to download a very large (two DVD) Dell "OpenManage" utility to be able to monitor the raid system and see what is a problem is that true?

How to add a writable folder to the PHP document root on linux

- by Ron Whites

We are building an example bash script for our PHP TestCoverage Tool use on Linux. The development environment is Ubuntu 12.04_1 but we intend to have the linux example work across as many linux versions as possible without modification. The example linux script requires a variable be set to the PHP Document Root path and by default uses a small PHP example source to show the user how our GUI and text report shows the covered and uncovered PHP code areas. The linux script is also intended to be easily alterable by the user to automate the TestCoverage display of users PHP code. The problem we are having with Ubuntu 12.04 (any linux?) is that the PHP Apache2 document root is defined in /etc/apache2/sites-available/default as /var/www and /var/www is defaulted with "drwxr-xr-x" read only access. So in order to add our own folder as /var/www/SDTestCoverage we must change /var/www to "drwxrwxrwx" read-write access. So it seems our script (at least on Ubuntu) will need to ... 1. acquire and save the /var/www permissions then do .. 2. sudo chmod 777 /var/www (to make writable) 3. mkdir -p /var/www/SDTestCoverage (create our folder under the document root) 4. sudo chmod 777 /var/www/SDTestCoverage (make our subfolder writable) 5. and finally restore /var/www permissions Thanks and our Questions are .. 1. Is this the standard way (using Ubuntu) one adds a writable folder under the PHP Document Root? 2. Is this the most general purpose way one adds a writable folder under the PHP Document Root on other versions of Linux?

With Ubuntu 12.04 unlike 11.04 Wine installed application start menu links are missing

- by Ron Whites

With Ubuntu 12.04 and wine 1.4 unlike ubuntu 11.04 with wine 1.2.2 installed application start menu links are missing. For instance with Ubuntu 11.04 including Wine I can install one of our Windows applications and then can go to Applications Wine Programs Semantic Designs TestCoverage Documentation to bring up the documentation for how to run our tool. Unfortunately with Ubuntu 12.04 the Applications menu is gone and going to Dash I do see "Recent Apps and more apps" but my installed Wine application and related documentation link is shown present, even though the wine uninstaller shows in present. I found this online suggestion and tried using the gnome "main menu"... Windows key to launch the Dash. Enter "Main Menu" in the search field and open the old Edit Main Menu app. Select the Category (aka Unity Dash Filter) you want the item in. Name the Dash/Launcher Item Add the Command to launch said app With "mainmenu" then get down to the TestCoverage Documentation and I could see a command link in properties of .. env WINEPREFIX="/home/sdtest/.wine" wine C:\windows\command\start.exe /Unix /home/sdtest/.wine/dosdevices/c:/users/sdtest/Start\ Menu/Programs/Semantic\ Designs/Test\ Coverage/Java\ 1.7\ Documentation.lnk BUT I could not execute this link to view the installed documentation. So I copied the link properties into a file, set it as executable, and ran it as a bash script and the documentation came up! So why can't I use this link under main menu?

Upgrade using downloaded $40 to Win8 x64 to blank SSD using only retail 32Bit XP install CD

- by Ron

Here is my situation. Purchase the downloadable $40 UPGRADE version of Windows 8. Install this upgrade to a new/blank SSD drive WITHOUT prior installation of retail version of XP/service pack 3 (prefered). I have the retail purchased 32Bit XP installation media and I also have a slipstreamed disc that contains service pack 2. This 32bit XP license was installed to a desktop PC that I have NOT used for years (its broke). Questions: Can I upgrade using the $40 download upgrade version from retail 32Bit XP to 64Bit Windows 8 directly to new SSD? without first installing 32bit XP to new SSD? If 32bit XP needs to be installed to perform the upgrade to 64bit Win 8 is service XP service pack 3 still available; likewise, if the boxed retail version of XP 32bit is required to be pre-installed to the new SSD before attempting the downoladed $40 upgrade to 64Bit Win, can a clean install be performed or is a undesired actual upgrade performed? From what I have read this is way to complicated. Ideally, I should be able to install $40 upgrade version Win 64bit directly to new/blank SSD, then during the license verification process enter both the Win8 64Bit upgrade key and retail XP 32bit key (over internet or phone call). Thanks Very Much In Advance for any insight!! Regards, Ron

micro-SD card initialization using SPI interface

- by Ron

I'm using a micro-SD card in an embedded design. The card is connected to a microcontroller using the SPI interface. It worked fine for all cards I've used before, but now my new card will not initialize. The card is a Transcend 2GB micro-SD card (TS2GUSD). After sending the initial clock train to switch to SPI mode I do the following: 1) CMD0 (Argument 0, CRC 0x95) - Response 0x01 - OK 2) CMD8 (Argument 0x000001AA, CRC 0x87) - Response 0x01 0x000001AA - Means it's SDC V2+ card, the Voltage range 2.7V~3.6V is supported - OK Then I should send the ACMD41 command, but when sending the CMD55 (argument 0, CRC 0) that must precede CMD41, I get response 0x05 - Illegal Command. I've also tried to send CMD1 (for MMC cards), but it gives a similar Illegal Command response. The code works fine with my Sandisk 2GB micro-SD card. Does anyone have any idea? Thanks, -Ron-

Android SDK - Animation prevents further events on View like OnClick()

- by Ron

I have an ImageView which is animated via startAnimation() to slide it into the screen. It is visible and enabled in the XML. When I add a Handler for a delay or an onClick event, nothing happens. When I remove the startAnimation() everything works fine. Except the animation of course. Heres my code: balloon.setOnClickListener(new OnClickListener() { @Override public void onClick(View view) { view.setVisibility(View.GONE); } }); Animation dropDown = AnimationUtils.loadAnimation(context, R.anim.balloon_slide_down); dropDown.setStartOffset(1500); balloon.startAnimation(dropDown); Any ideas why that is? I'm quite frustrated by now... Thanks, Ron

Java Design Questions - Class, Function, Access Modifiers

- by Ron

I am newbie to Java. I have some design questions. Say I have a crawler application, that does the following: 1. Crawls a url and gets its content 2. Parses the contents 3. Displays the contents How do you decide between implementing a function or a class? -- Should the parser be a function of the crawler class, or should it be a class in itself, so it can be used by other applications as well? -- If it should be a class, should it be protected or public class? How do you decide between implementing a public or protected class? -- If I had to create a class to generate stats from the parsed contents for eg, should that class be protected (so only the crawler class can access it) or should it be public? Thanks Ron

Hi guys. I have an Apache server running PHP. Everything works fine. But If I have a script that runs for a long time, and I try to open another page to the same server, the second page waits till my first page finishes. This behavior happens to me on Linux and PC. I'm running Apache V2.2.9, and PHP 5.2.6. I'm not sure why this happens... is this normal behavior? Ron

sending control+c (SIGINT) to NSPIPE in objective-c

- by Ron

Hello, I am trying to terminate an openvpn task, spawned via NSTask. My question: Should I send ctrl+c (SIGINT) to the input NSPipe for my NSTask? inputPipe = [NSPipe pipe]; taskInput = [inputPipe fileHandleForWriting]; NSString dataString = @"\cC"; [taskInput writeData:[dataString dataUsingEncoding: [NSString defaultCStringEncoding]]]; Alternatively, I was thinking about using kill( pid, SIGINT ); but it would be much more complicated since the process ID has to be determined via a detour ([task processIdentifier] does not help here) - the original NSTask calls: /bin/bash -c sudo -S | mypassword .... That's not nice, I know but it is only called once and the sudo password has been entered in that case already. thanks for any suggestions/opinions/etc. Ron

What do you think are the biggest software development issues, in small to medium businesses?

- by Ron-Damon

Hi, I own a small software development company that developes Web software to other small and medium companies in Chile. The business process is very complex and it is hard to stablish where to put the efforts to make our company better, more efficient, and give better solutions. I'm also a TI master's degree student and i'm making a paper about this subject, so any help would be great to help my company and my paper. I have considered 3 areas for the problems: 1) Software development problems 2) Web development problems 3) Small and Medium companies problems I don't know about you, but at least this "business formula" in Chile has not received very much support but it is getting better, but today my company is far from being self-sufficient. UPDATE: Thanks guys for your support so far, i'm updating because i have somewhat enough information so i decided to go deeper within the subjects, wish i would like you to consider for your next answers/commentaries on the subject: 1) Software development problems (3) 1.1 Incomplete problem picture 1.2 Useless delivered software 1.3 Unrealistic or inadequate schedule 2) Web development problems (3) 2.1 Apparently non-viable implementation 2.2 Unefficient module construction design 2.3 Reduced result system inter-operability 3) Small and Medium companies problems (3) 3.1 Very specific, but narrowed requerired system characteristics 3.2 Developed system is not used 3.3 Positivist demand for activities in project execution There are only 3 problems for category, to deliberately keep a thiner scope. Also, i have considered that it would have been apropiated to separate the third clasification on two, but won't be doing it just now: 3) Small and Medium software developement providers problems 4) Small and Medium software developement clients problems In that case, i think i would have made the scope of the problem wider and it is not what i want to do now, until at least i'm very trough with the other two clasifications. What you think?

Is there a Content Management System that allows multiple & independent blogs to be running on one domain?

- by Ron

Hello Webmasters, I am a Wordpress fan, and I'm now building a new site and I'm not sure which CMS can achieve what I'm trying to do. I am building a food blog network for a bunch of cities in the US, and I want to my city pages to be independently running blogs themselves. So basically... Home Page - Its own blog with its own users, talking about Food in general Dallas Page (child of home page) - Its own blog with its own users Chicago Page ..... so on and so forth. The web layout and design will be all the same, but just trying to achieve 25~50 independent blogs on one domain. How can I achieve this? I'm hoping that I don't have to install Wordpress into as many subdomains that I create... Thank you for your help in advance. -RP

Ubuntu sudo not working

- by Ron Sebastian

I wanted to move a file to a /usr/python2.7/ but i was unable to do so, so i changed the permissions of /usr to myuser: sudo chown -R ***** /usr it worked but i realised it was a blunder when sudo stopped working after that. It says: sudo: effective uid is not 0, is sudo installed setuid root? I have seen this post where the accepted solution was to use the policykit: pkexec chown root:root /usr/bin/sudo pkexec chmod 4755 /usr/bin/sudo however, even the policykit is saying that: pkexec must be setuid root please help, i've learned a lesson and will never change permissions for /usr again. Please help me this time!
