• How can I make sure my evening project code is mine?

  - by Sebastian

  I'm a physicist with a CS degree and just started my PhD at a tech company (wanted to do applied research). It deals with large scale finite element simulations. After reviewing their current approach, I think that a radically different method has to be applied (they are using a commercial tool which is very limited). I'd rather base my research on an open source finite element solver and write a program which makes use of it. I'd like to develop this idea in the evenings, because that's the time that best suits me for programming (during the day I prefer reading and maths) and use it at a late stage of my PhD. I'd like to have the option to release my program as open source on my website as a reference, for future personal or even commercial (e.g. consulting) use. How can I make sure that my company doesn't claim the code ownership? I don't really I thought that a version control system could help (check out only in the evening). This would document that I programmed not during regular office hours (documented elsewhere). But these data can be easily manufactured. Any other ideas? I want to stress that I'm not interested in selling software. Jurisdiction is EU, if that matters. Thank you.

• How to open-source a project whose git repository has copyrighted media in the history?

  - by phyzome

  I want to release an audio fingerprinting software project under a free license, but the repository contains copyrighted audio files. The test cases also currently use these files. How do I release the code to the public with maximum version history but without violating copyright? Details: The code is versioned under git. We will collapse it all back into one branch before release. There are 400 MB of audio data. Some files are free-licensed music from e.g. Jamendo, others are MP3s from our personal collections. No matter what approach we take, we'll always keep an immutable copy of the original repo, so as not to destroy project history. Main question: How to handle the public release? Expunge all history of the files in question from the git repository and release the altered repo. (v64 pointed out a way to do this.) Alternatively, take a snapshot of the current state of the code and don't even bother having a public history of the pre-release code. Side question: How could we have avoided this dilemma in the first place, given that sometimes private code or media is needed for the early stages of a project?

• How to disable the link MissingFile on Shotwell

  - by user86865

  I have some personal photos which are encrypted by CryptKeeper. I doesn't like to disclose them to anyone. Whenever i lke to view them, I mount them using CryptKeeper. I need to include these photos in Shotwell photo manager at the time of mounting. So, I mounted them using CryptKeeper. Then I imported them to Shotwell. I made a new event and etc to organize and view those photos. After that I unmounted them using CryptKeeper because someone may see it. Now I don't want any single trail on Shotwell beacuse of the same problem. But there is a new button 'MissingFiles' appeared and when i clicked on it, all the photo thumbnail which i unmounted showed there. I dont't want right'click on them and select 'remove from library'; beacuse when i want to view them next time on Shotwell, I need to import, organize, etc at that time. So, the only option here is to disable the unavailability of that MisssingFiles button.

• To program in free time as a programmer, is to show that programming is passion. If not, is the programmer good? [closed]

  - by SonofWatson

  Possible Duplicate: I don't program in my spare time. Does that make me a bad developer? A lot of blogs and advice on the web seem to suggest that in order to become a great developer, doing just your day job is not enough. For example, you should contribute to open source projects in your spare time, write smartphone apps, etc. In fact a lot of this advice seems to suggest that if you don't love programming enough to do it all day long then you're probably in the wrong career. That doesn't ring true with me. I enjoy my work, but when I come home from the office I'm not in the mood to jump straight back onto the computer and start coding away until bedtime. I only have a certain number of hours free time each day, and I'd rather spend them on other hobbies, seeing friends or going outside than in front of the computer. I do get a kick out of programming, and do hack around outside of work occasionally. I'm committed to my personal development and spend time reading tech blogs and books as a way to keep learning and becoming better. But that doesn't extend so far as to my wanting to use all my spare time for coding. Does this mean I'm not a 'true' software developer at heart? Is it possible to become a good software developer without doing extra outside your job? I'd be very interested to hear what you think.

• UCS Documentation: Home1 or Home2? You Decide.

  - by joesciallo

  How you go about finding information can be a very personal affair. We each have our own style of locating content, we each have our particular bent. But when it comes to getting started finding technical information, sometimes the simplest ways are best, especially if you are relatively new to a product or technology, and you just need to get going quickly with that Installation Guide or those Release Notes. With that in mind, I recently created an alternative home page for the Unified Communications Suite documentation. You can now have your Home2, in addition to the original, more wiki-fied Home1. I would recommend Home2 for those who are used to, and are more comfortable with, the spreadsheet-like view of manuals: here you'll find those familiar titles and the option to either view on the wiki or download the equivalent PDF file. Once you get familiar with what guides are available for the UCS component products, then move on to the Home1 layout, and start using some of the more advanced techniques for finding content in a wiki. Either way, you should be able to locate the "thing" you are looking for.

• Problem with understanding how to start

  - by Coolface

  Okay, this might be a little off-topic but i try anyway. Sorry to bother. So i'm working as sysadmin for at least 5 years now and i quite enjoy IT field in general. Somehow i was never interested in programming much but always want to learn something at least easy and for personal usage. As sysadmin i need scripting skills so learn shell scripting without much problems, i also try to learn pascal, delphi, basic over time and must recent was python. Well, my problem is when i try to learn programming i just can't apply what i learn from the books to the real word. What i mean is i understand there are data structures, algorithms, variables, lib's, if-then logic, etc. but i just can't understand how to apply this things when i want to do real things. Like i want to get a something simple as parse web page, i draw a quick algorithm like get a web page, find a word on it and write a to file, on the paper everything look simple but when i get to the coding i just stuck pretty much from the start. I try read code of the real programs that just totally confusing especially big parts with many classes so i'm just quickly lost a trail what this code do. I think i just lack some fundamentals to see a big picture but don't really know what this might be? Or maybe i just don't have a passion to programming at all... My best bet was a shell scripting so i have really no problems to write complex scripts but this just not enough. Recently i was read around 5 or 6 python books because everyone say it's so easy even kid can code something but still no much luck, python is good and easy but i can't make something harder then a prodecurial style code like in bash for easy things but when i want harder things i'm still stuck. In college i was also not a math and tech guy and like to study non-tech stuff mostly like economy, psychology maybe that my problem? Anyway any advice would be greatly appriciated.

• Best practice for storing information from a php script for future use

  - by tRudgeF3llow

  My employer uses forms to help people search for products. The product lists can change from time to time and the forms need to be updated again. The product information can be accessed through a third party API which I started tinkering with, I've recently built a script that retrieves the information with PHP and creates and populates a form dynamically with Javascript. So far so good, but... There are limitations to the API, mainly it can only be accessed a certain number of times per hour, it is probably more than my form/script would use but I want to create a script that is minimally intrusive. My main question is... What is the best practice for accessing the information once and storing it long enough to let the API reset? I was wondering about creating a cookie but there is the possibility of users that have them disabled. (Also, I am doing this as a personal project but I like the people I work for and I think this would help them out.) Thanks in advance.

• What is the correct way to code incoming links for SEO?

  - by DC01

  Our site is giving out 'badges' to our authors. They can post these on their personal blogs and they will serve as incoming links to our site. We want to give out the best possible code for SEO without doing anything that would get us flagged. I would like to know what you're thoughts are on the following snippet of code and if anyone has any DEFINITE advice on dos and donts with it. Also, let me know if any of it is redundant or not worth it for SEO purposes. I've kept the css inline since some of the writers would not have access to add link to external CSS. I've changed the real values, but title, alt etc would be descriptive keywords similar to our page titles etc (no overloading keywords or any of that) <div id="writer" style="width:100px;height:50px;> <h1><strong style="float:left;text-indent:-9999px;overflow:hidden;margin:0;padding:0;">articles on x,y,z</strong> <a href="http://www.site.com/link-to-author" title="site description"> <img style="border:none" src="http://www.site.com/images/badge.png" alt="description of articles" title="View my published work on site.com"/> </a> </h1></div>

• Web hosting deciding to pay for hosting or host your own?

  - by pllee

  Is there a guide out there on how to choose when to pay for web hosting vs. hosting your own? Assuming that root access is a must I would like to compare things like cost, scalability and personal stress. Here is what I could come up with. Paying for web hosting: Benefits: Much cheaper for a small scale. I assume anything under $50 a month would be cheaper than paying for the bandwidth of hosting. No stress in dealing with power outages, server restarts or internet going down. For the most part less busy work involved with setting up. Negatives: Cost goes way up when higher specs are needed (for example monthly cost triples with ability to use 8gb of ram that you can buy for $90 ). This means you have to target a particular ram usage and monitor so your instance stays within the threshold. root access for the most part is a premium. You may get tied into a vendor specific deployment process. Hosting on own : Positives: 100% control of specs and software. When you get past paying for the bandwidth you get much more bang for your buck by building your own machine. Negatives: Doesn't make financial sense if bandwidth costs are more than web hosting costs. Having to deal with power outages, server restarts or internet going down. I think the best of both worlds would be if there was a place that dealt with bandwidth, power outages and server restarts but you provided your own server. Kind of like a 24 hour day care for a server. Does anything like that exist?

• Web Host which provides Latex and embedded programming [duplicate]

  - by Polymer

  This question already has an answer here: How to find web hosting that meets my requirements? 5 answers Hopefully this is a reasonable place to ask this question. I'll confess I'm a little green when it comes to web programming and websites in general (though not programming). I'm a Math and Physics person. I want to make a personal webpage containing a Math and Physics blog. Ideally the blog should support latex, and embedded programs. This would allow me to write, say, an equation for an orbit and then show what the orbit would look like (perhaps letting the reader configure parameters). The programming language can be javascript (though it isn't my favorite language). My budget is around 5 dollars a month. Does anybody have suggestions for a good Shared host with these kind of requirements? And a small aside, It would be useful if I can move the website content, since I might live at a university in the nearish future. They would have servers which could support such a webpage.

• Pass a single boolean from an Android App to a libgdx game

  - by Doug Henning

  I'm writing an Android application that needs to pass a single boolean into an Android game that I am also writing. The idea is that the user does something in the App which will affect how the game operates. This is tricky with LIBGDX since I need to get the bool value into the Java files of the game, but of course, you can't call Android specific things from within LIBGDX's main Java files. I tried using an intent but of course the same problem persists. I can get the boolean into the MainActivity.Java of the android output of the game, but can't pass it along any further since the android output and the main java files don't know about each other. I have seen a few tutorials that explain how to use set up an interface in the LIBGDX java files that can call android things. This seems like wild overkill for what I want to do. I've been trying to use Android's Shared Preferences with LIBGDX's Gdx.app.getPreferences, but I can't make it work. Anyhelp would be MUCH appreciated. I've set up two hello world applications. One is a standard Android app, with a single button that is supposed to write "true" into the shared preferences. The other is a standard LIBGDX hello world that is supposed to do nothing but check that bool when launched and if true display one image to the screen, if false, display a different one. Here's the relevant bit of the Android code: import android.preference.PreferenceManager; public void onClick(View view) { if (view == this.boolButton){ final String PREF_FILE_NAME = "myBool"; SharedPreferences preferences = getSharedPreferences(PREF_FILE_NAME, MODE_WORLD_WRITEABLE); SharedPreferences.Editor editor = preferences.edit(); editor.putBoolean("myBool", true); editor.commit(); } } And here's the relevant bit of the code from the LIBGDX main file: Preferences prefs = Gdx.app.getPreferences("myBool"); boolean switcher = prefs.getBoolean("myBool"); if(switcher == true){ texture = new Texture(Gdx.files.internal("data/worked512.png")); prefs.putBoolean("myBool", false); } else { texture = new Texture(Gdx.files.internal("data/libgdx.png")); } Everything compiles fine, it just doesn't work. I've spent HOURS googling trying to find a way to pass this single boolean from android into a LIBGDX main and I'm totally stumped. Thanks for your help.

• Disable Opera Thumbnail Previews on Windows 7 Taskbar

  - by Asian Angel

  If you are one of the people who does not care for the Taskbar Thumbnail Previews in Windows 7 then we have a quick and easy way for you to turn them off in Opera Browser. Before Here is our Opera Browser with four tabs full of HTG Network goodness… Hovering the mouse over the Taskbar Icon gives a nice preview of each tabs content. Looking closer you can see the fanned edge on the Taskbar Icon indicating that there are multiple tabs open. This is all good but what if you just want something simpler? Disabling the Previews If you want to disable the Taskbar Thumbnail Previews in Opera you will need to type opera:config in the Address Bar and press Enter. Once you have done that, you will see a condensed listing for all of Opera’s preferences. There is one Preference Category that we need to look for…User Prefs. Note: While a Quick Find Search could be conducted for the entry that needs to be modified, we have chosen to show the full method here. After scrolling down and finding the User Prefs category you will need to expand the section. Notice the size of the scrollbar in comparison with the screenshot above…there is quite a lot that you can look at and finesse in Opera if desired. Scroll down until you find the Use Windows 7 Taskbar Thumbnails entry. Uncheck the box but do not close the opera:config Tab yet…or your changes will not take effect. Scroll down once more until you reach the end of the User Prefs category and click Save. With this particular modification you will need to restart Opera after clicking OK. After restarting Opera the Taskbar Icon and Taskbar Thumbnail Preview will revert to the minimal Windows 7 default as shown here. You can see Opera’s Tab Bar in the thumbnail and the Taskbar Icon no longer has a “fanned edge”. Conclusion If you want to disable Opera’s Taskbar Thumbnail Previews on your Windows 7 system, then this quick modification will help get it sorted out in just a few moments.

• Round Table - Minimum Cost Algorithm

  - by 7Aces

  Problem Link - http://www.iarcs.org.in/zco2013/index.php/problems/ROUNDTABLE It's dinner time in Castle Camelot, and the fearsome Knights of the Round Table are clamouring for dessert. You, the chef, are in a soup. There are N knights, including King Arthur, each with a different preference for dessert, but you cannot afford to make desserts for all of them. You are given the cost of manufacturing each Knight's preferred dessert-since it is a round table, the list starts with the cost of King Arthur's dessert, and goes counter-clockwise. You decide to pick the cheapest desserts to make, such that for every pair of adjacent Knights, at least one gets his dessert. This will ensure that the Knights do not protest. What is the minimum cost of tonight's dinner, given this condition? I used the Dynamic Programming approach, considering the smallest of i-1 & i-2, & came up with the following code - #include<cstdio> #include<algorithm> using namespace std; int main() { int n,i,j,c,f; scanf("%d",&n); int k[n],m[n][2]; for(i=0;i<n;++i) scanf("%d",&k[i]); m[0][0]=k[0]; m[0][1]=0; m[1][0]=k[1]; m[1][1]=1; for(i=2;i<n;++i) { c=1000; for(j=i-2;j<i;++j) { if(m[j][0]<c) { c=m[j][0]; f=m[j][1];} } m[i][0]=c+k[i]; m[i][1]=f; } if(m[n-2][0]<m[n-1][0] && m[n-2][1]==0) printf("%d\n",m[n-2][0]); else printf("%d\n",m[n-1][0]); } I used the second dimension of the m array to store from which knight the given sequence started (1st or 2nd). I had to do this because of the case when m[n-2]<m[n-1] but the sequence started from knight 2, since that would create two adjacent knights without dessert. The problem arises because of the table's round shape. Now an anomaly arises when I consider the case - 2 1 1 2 1 2. The program gives an answer 5 when the answer should be 4, by picking the 1st, 3rd & 5th knight. At this point, I started to doubt my initial algorithm (approach) itself! Where did I go wrong?

• On SQL Developer and TNSNAMES.ORA

  - by thatjeffsmith

  Tnsnames.ora [DOCS] is a configuration file for SQL*Net that describes the network service names for the databases in your organization. Basically, it tells Oracle applications how to find your databases. This post is just a quick overview on how to get SQL Developer to ‘see’ this file and define a connection. There’s only a single prerequisite for having SQL Devleoper setup such that it can use TNSNAMES to connect: You have somewhere a tnsnames.ora file You don’t need a client, instant or otherwise, on your machine. You just need the file. Now, if you DO you have a client or HOME on your machine, SQL Developer will look for those and find the tnsnames file for you. IF we can’t find it at the usual places, you can simply tell us where it is via this preference: On the Database – Advanced page Once you’ve done this, assuming you have a file (or 10) in that directory, we’ll read it, parse it, and list the entries in the connection dialog. The File(s) That’s right, files. Just like SQL*Plus, we’ll read any file that starts with ‘tnsnames’ – that includes files you’ve renamed to .bak or .old. Kris talks about that more here. I have just the one, which is all I need anyway. There we go! Defining the Connection Just set the connection type to TNS. This is a lot easier to do than manually defining the connections – esp as they’re likely to frequently change in ‘the real world.’ No Client or Home Required That’s right. You don’t need an Oracle Client or $ORACLE_HOME to have SQL Developer see and read a TNS file. Just so you know I’m not cheating… SQL Dev doesn’t know which client to use and won’t use it even if it DID know… I’m able to define a new connection AND connect with these preferences ON|OFF.

• How To Remove Hyperlinks from Microsoft Word Documents

  - by Mysticgeek

  Sometimes when you copy text from a webpage and paste it into Word, it can be annoying when the hyperlinks transfer with it. Today we take a look at how to easily remove the hyperlinks if you don’t want them in the document. Here we will cover a few different ways you can remove hyperlinks from emails or webpage data that you enter into a Word document using Paste Special and Keyboard Shortcuts. Remove Hyperlinks in Word Using Paste Special In Word 2010 we copied part of an article from How-To Geek, as you can see the hyperlinks were copied into the document as well. To remove the hyperlinks right-click on the document and you’ll see three icons under Paste Options. We want to select the third one to the right which is Keep Text Only…the text in in the document changes so you can get a preview of how it will look. After selecting Keep Text Only, you can see the hyperlinks have been removed. However, you’ll need to change the fonts and other layouts if you’re not happy with the default of Calibri. In Office 2007 under the Home tab click the dropdown menu under Paste and select Paste Special. In the Paste Special screen select Unformatted Text then click OK. In Office 2003 copy the text into the document, hover your mouse over the clipboard, click the dropdown menu, then select Keep Text Only. Keyboard Ninja Style If you’re a Keyboard Ninja, an easy way to remove all hyperlinks is to use “Ctrl+A” to select everything, then use the key combination “Ctrl+Shift+F9”…We tested this key combination and it works in Word 2003-2010. This will remove all of the hyperlinks and keep the original format of the text. Conclusion There are several different ways to get rid of hyperlinks in text pasted into Word documents. The method you use will depend on your preference and the version of Word you’re using…but the “Ctrl+Shift+F9” keyboard shortcut works in all versions of Word and might be the easiest way. If you always want just text in Word 2007, you can disable automatically disable them. If you have a different method you use to remove hyperlinks from Word documents, leave a comment and let us know!

• SQL SERVER – Validating Spatial Object as NULL using IsNULL

  - by pinaldave

  Follow up questions are the most fun part of writing a blog post. Earlier I wrote about SQL SERVER – Validating Spatial Object with IsValidDetailed Function and today I received a follow up question on the same subject. The question was mainly about how NULL is handled by spatial functions. Well, NULL is NULL. It is very easy to work with NULL. There are two different ways to validate if the passed in the value is NULL or not. 1) Using IsNULL Function IsNULL function validates if the object is null or not, if object is not null it will return you value 0 and if object is NULL it will return you the value NULL. DECLARE @p GEOMETRY = 'Polygon((2 2, 3 3, 4 4, 5 5, 6 6, 2 2))' SELECT @p.ISNULL ObjIsNull GO DECLARE @p GEOMETRY = NULL SELECT @p.ISNULL ObjIsNull GO 2) Using IsValidDetailed Function IsValidateDetails function validates if the object is valid or not. If the object is valid it will return 24400: Valid but if the object is not valid it will give message with the error number. In case object is NULL it will return the value as NULL. DECLARE @p GEOMETRY = 'Polygon((2 2, 3 3, 4 4, 5 5, 6 6, 2 2))' SELECT @p.IsValidDetailed() IsValid GO DECLARE @p GEOMETRY = NULL SELECT @p.IsValidDetailed() IsValid GO When to use what? Now you can see that there are two different ways to validate the NULL values. I personally have no preference about using one over another. However, there is one clear difference between them. In case of the IsValidDetailed Function the return value is nvarchar(max) and it is not always possible to compare the value with nvarchar(max). Whereas the ISNULL function returns the bit value of 0 when the object is null and it is easy to determine if the object is null or not in the case of ISNULL function. Additionally, ISNULL function does not check if the object is valid or not and will return the value 0 if the object is not NULL. Now you know even though either of the function can be used in place of each other both have very specific use case. Use the one which fits your business case.

• On Writing Blogs

  - by Tony Davis

  Why are so many blogs about IT so difficult to read? Over at SQLServerCentral.com, we do a special subscription-only newsletter called Database Weekly. Every other week, it is my turn to look through all the blogs, news and events that might be of relevance to people working with databases. We provide the title, with the link, and a short abstract of what you can expect to read. It is a popular service with close to a million subscribers. You might think that this is a happy and fascinating task. Sometimes, yes. If a blog comes to the point quickly, and says something both interesting and original, then it has our immediate attention. If it backs up what it says with supporting material, then it is more-or-less home and dry, featured in DBW's list. If it also takes trouble over the formatting and presentation, maybe with an illustration or two and any code well-formatted, then we are agog with joy and it is marked as a must-visit destination in our blog roll. More often, however, a task that should be fun becomes a routine chore, and the effort of trawling so many badly-written blogs is enough to make any conscientious Health & Safety officer whistle through their teeth at the risk to the editor's spiritual and psychological well-being. And yet, frustratingly, most blogs could be improved very easily. There is, I believe, a simple formula for a successful blog. First, choose a single topic that is reasonably fresh and interesting. Second, get to the point quickly; explain in the first paragraph exactly what the blog is about, and then stay on topic. In writing the first paragraph, you must picture yourself as a pilot, hearing the smooth roar of the engines as your plane gracefully takes air. Too often, however, the accompanying sound is that of the engine stuttering before the plane veers off the runway into a field, and a wheel falls off. The author meanders around the topic without getting to the point, and takes frequent off-radar diversions to talk about themselves, or the weather, or which friends have recently tagged them. This might work if you're J.D Salinger, or James Joyce, but it doesn't help a technical blog. Sometimes, the writing is so convoluted that we are entirely defeated in our quest to shoehorn its meaning into a simple summary sentence. Finally, write simply, in plain English, and in a conversational way such that you can read it out loud, and sound natural. That's it! If you could also avoid any references to The Matrix then this is a bonus but is purely personal preference. Cheers, Tony.

• Change default language settings in Visual Studio 2012

  The first thing you need to do after the installation of Visual Studio 2012 is to choose the IDE preferences. Once you select your preferred collection of settings, the IDE will always choose dialogs and other options according to your selection. Nowadays developer’s needs to work with different programming environments and due to this, developers might need to reset the default settings. In this article, I am going to demonstrate how you can change the default settings in Visual Studio 2012. For the purpose of this demonstration, I have installed Visual Studio 2012 and selected C++ as my default environment settings. So now when I go to file -> new project, it will give me C++ templates by default as follows. If you want to select another language, you need to expand Other Languages section and select C# or VB. Now I am going to change these default settings. I am going to change the default language preference to C#. In Visual Studio 2012, go to tools menu and select Import and Export Settings. Here you have 3 options; one is to export the current settings so that the settings are saved for future use. Also you can import previously saved settings. The last option available is to reset it to default. It is a good Idea to export your settings and import it as you need in later stages. To reset the settings to default select the Reset option and click next. Now Visual Studio will ask you to whether you would like to save the settings, which can be used in future to restore. Select any one option and click next. For the purpose of this demo, I have selected not to save the settings. Click Next button to continue. Now Visual Studio will bring you the similar dialog that appears just after installation to select your IDE settings. Select the required settings from the available list and click Finish button. Click Finish once you are done. If everything OK, you will see the success message as below. Now go to file -> new Project, you will see the selected language appear by default. I selected C# in the previous step and the new project dialog appears as follows. Changing IDE settings in Visual Studio 2012 is very easy and straight forward.

• SQL Developer Debugging, Watches, Smart Data, & Data

  - by thatjeffsmith

  After presenting the SQL Developer PL/SQL debugger for about an hour yesterday at KScope12 in San Antonio, my boss came up and asked, “Now, would you really want to know what the Smart Data panel does?” Apparently I had ‘made up’ my own story about what that panel’s intent is based on my experience with it. Not good Jeff, not good. It was a very small point of my presentation, but I probably should have read the docs. The Smart Data tab displays information about variables, using your Debugger: Smart Data preferences. You can also specify these preferences by right-clicking in the Smart Data window and selecting Preferences. Debugger Smart Data Preferences, control number of variables to display The Smart Data panel auto-inspects the last X accessed variables. So if you have a program with 26 variables, instead of showing you all 26, it will just show you the last two variables that were referenced in your program. If you were to click on the ‘Data’ debug panel, you’ll see EVERYTHING. And if you only want to see a very specific set of values, then you should use Watches. The Smart Data Panel As I step through the code, the variables being tracked change as they are referenced. Only the most recent ones display. This is controlled by the ‘Maximum Locations to Remember’ preference. Step through the code, see the latest variables accessed The Data Panel All variables are displayed. Might be information overload on large PL/SQL programs where you have many dozens or even hundreds of variables to track. Shows everything all the time Watches Watches are added manually and only show what you ask for. Data on Demand – add a watch to track a specific variable Remember, you can interact with your data If you want to do more than just watch, you can mouse-right on a data element, and change the value of the variable as the program is running. This is one of the primary benefits to debugging over using DBMS_OUTPUT to track what’s happening in your program. Change the values while the program is running to test your ‘What if?’ scenarios

• Where to draw the line between development-led security and administration-led security?

  - by haylem

  There are cases where you have the opportunity, as a developer, to enforce stricter security features and protections on a software, though they could very well be managed at an environmental level (ie, the operating system would take care of it). Where would you say you draw the line, and what elements do you factor in your decision? Concrete Examples User Management is the OS's responsibility Not exactly meant as a security feature, but in a similar case Google Chrome used to not allow separate profiles. The invoked reason (though it now supports multiple profiles for a same OS user) used to be that user management was the operating system's responsibility. Disabling Web-Form Fields A recurrent request I see addressed online is to have auto-completion be disabled on form fields. Auto-completion didn't exist in old browsers, and was a welcome feature at the time it was introduced for people who needed to fill in forms often. But it also brought in some security concerns, and so some browsers started to implement, on top of the (obviously needed) setting in their own preference/customization panel, an autocomplete attribute for form or input fields. And this has now been introduced into the upcoming HTML5 standard. For browsers who do not listen to this attribute, strange hacks *\ are offered, like generating unique IDs and names for fields to avoid them from being suggested in future forms (which comes with another herd of issues, like polluting your local auto-fill cache and not preventing a password from being stored in it, but instead probably duplicating its occurences). In this particular case, and others, I'd argue that this is a user setting and that it's the user's desire and the user's responsibility to enable or disable auto-fill (by disabling the feature altogether). And if it is based on an internal policy and security requirement in a corporate environment, then substitute the user for the administrator in the above. I assume it could be counter-argued that the user may want to access non-critical applications (or sites) with this handy feature enabled, and critical applications with this feature disabled. But then I'd think that's what security zones are for (in some browsers), or the sign that you need a more secure (and dedicated) environment / account to use these applications. * I obviously don't deny the ingenuity of the people who were forced to find workarounds, just the necessity of said workarounds. Questions That was a tad long-winded, so I guess my questions are: Would you in general consider it to be the application's (hence, the developer's) responsiblity? Where do you draw the line, if not in the "general" case?

• Poll Results: Foreign Key Constraints

  - by Darren Gosbell

  A few weeks ago I did the following post asking people – if they used foreign key constraints in their star schemas. The poll is still open if you are interested in adding to it, but here is what the chart looks like as of today. (at the bottom of the poll itself there is a link to the live results, unfortunately I cannot link the live results in here as the blogging platform blocks the required javascript)   Interestingly the results are fairly even. Of the 78 respondents, fractionally over half at least aim to start with referential integrity in their star schemas. I did not want to influence the results by sharing my opinion, but my personal preference is to always aim to have foreign key constraints. But at the same time, I am pragmatic about it, I do have projects where for various reasons some constraints are not defined. And I also have other designs that I have inherited, where it would just be too much work to go back and add foreign key constraints. If you are going to implement foreign keys in your star schema, they really need to be there at the start. In fact this poll was was the result of a feature request for BIDSHelper asking for a feature to check for null/missing foreign keys and I am entirely convinced that BIDS is the wrong place for this sort of functionality. BIDS is a design tool, your data needs to be constantly checked for consistency. It's not that I think that it's impossible to get a design working without foreign key constraints, but I like the idea of failing as soon as possible if there is an error and enforcing foreign key constraints lets me "fail early" if there are constancy issues with my data. By far the biggest concern with foreign keys is performance and I suppose I'm curious as to how often people actually measure and quantify this. I worked on a project a number of years ago that had very large data volumes and we did find that foreign key constraints did have a measurable impact, but what we did was to disable the constraints before loading the data, then enabled and checked them afterwards. This saved as time (although not as much as not having constraints at all), but still let us know early in the process if there were any consistency issues. For the people that do not have consistent data, if you have ETL processes that you control that are building your star schema which you also control, then to be blunt you only have yourself to blame. It is the job of the ETL process to make the data consistent. There are techniques for handling situations like missing data as well as  early and late arriving data. Ralph Kimball's book – The Data Warehouse Toolkit goes through some design patterns for handling data consistency. Having foreign key relationships can also help the relational engine to optimize queries as noted in this recent blog post by Boyan Penev

• Creating metadata value relationships

  - by kyle.hatlestad

  I was recently asked an question about an interesting use case. They wanted content to be submitted into UCM with a particular ID in a custom metadata field. But they wanted that ID to be translated during submission into an employee name in another metadata field upon submission. My initial thought was that this could be done with a dependent choice list (DCL). One option list field driving the choices in another. But this didn't work in this case for a couple of reasons. First, the number of IDs could potentially be very large. So making that into a drop-down list would not be practical. The preference would be for that field to simply be a text field to type in the ID. Secondly, data could be submitted through different methods other then the web-based check-in form. And without an interface to select the DCL choices, the system needed a way to determine and populate the name field. So instead I went the approach of having the value of the ID field drive the value of the Name field using the derived field approach in my rule. In looking at it though, it was easy to simply copy the value of the ID field into the Name field...but to have it look up and translate the value proved to be the tricky part. So here is the approach I took... First I created my two metadata fields as standard text fields in the Configuration Manager applet. Next I create a table that stores the relationship between the IDs and Names. I then create a View into that table and set the column to the EmployeeID. I now create a new Application Field and set it as an option list using the View I created in the previous step. The reason I create it as an Application field is because I don't need to display the field or store a value in it. I simply need to make use of the option list in the next step... Finally, I create a Rule in which I select the Employee Name field and turn on the 'Is derived field' checkbox. I edit the derived value and add a new condition. Because the option list is a Application field and not an Information field, I can't use the Compute button. Instead, I insert this line directly in the Value field: @getFieldViewValue("EmployeeMapping",#active.xEmployeeID, "EmployeeName") The "EmployeeMapping" parameter designates that the value should be pulled from the EmployeeMapping Application field that I had created in the previous step. The #active.xEmployeeID field is the ID value that should be pulled from what the user entered. "EmployeeName" is the column name in the table which has the value which corresponds to the ID. The extracted name then becomes the value within our Employee Name field. That's it. You can then add additional Rules to make the Name field read-only/hidden on the check-in page and such.

• Running Multiple Queries in Oracle SQL Developer

  - by thatjeffsmith

  There are two methods for running queries in SQL Developer: Run Statement Run Statement, Shift+Enter, F9, or this button Run Script No grids, just script (SQL*Plus like) ouput is fine, thank you very much! What’s the Difference? There are some obvious differences between the two features, the most obvious being the format of the output delivered. But there are some other, more subtle differences here, primarily around fetching. What is Fetch? After you run send your query to Oracle, it has to do 3 things: Parse Execute Fetch Technically it has to do at least 2 things, and sometimes only 1. But, to get the data back to the user, the fetch must occur. If you have a 10 row query or a 1,000,000 row query, this can mean 1 or many fetches in groups of records. Ok, before I went on the Fetch tangent, I said there were two ways to run statements in SQL Developer: Run Statement Run statement brings your query results to a grid with a single fetch. The user sees 50, 100, 500, etc rows come back, but SQL Developer and the database know that there are more rows waiting to be retrieved. The process on the server that was used to execute the query is still hanging around too. To alleviate this, increase your fetch size to 500. Every query ran will come back with the first 500 rows, and rows will be continued to be fetched in 500 row increments. You’ll then see most of your ad hoc queries complete with a single fetch. Scroll down, or hit Ctrl+End to force a full fetch and get all your rows back. Run Script Run Script runs the contents of the worksheet (or what’s highlighted) as a ‘script.’ What does that mean exactly? Think of this as being equivalent to running this in SQL*Plus: @my_script.sql; Each statement is executed. Also, ALL rows are fetched. So once it’s finished executing, there are no open cursors left around. The more obvious difference here is that the output comes back formatted as plain old text. Run one or more commands plus SQL*Plus commands like SET and SPOOL The Trick: Run Statement Works With Multiple Statements! It says ‘run statement,’ but if you select more than one with your mouse and hit the button – it will run each and throw the results to 1 grid for each statement. If you mouse hover over the Query Result panel tab, SQL Developer will tell you the query used to populate that grid. This will work regardless of what you have this preference set to: DATABASE – WORKSHEET – SHOW QUERY RESULTS IN NEW TABS Mind the fetch though! Close those cursors by bring back all the records or closing the grids when you’re done with them.
