• SQLAuthority News – A Conversation with an Old Friend – Sri Sridharan

  - by pinaldave

  Sri Sridharan is my old friend and we often talk on GTalk. The subject varies from Life in India/USA, movies, musics, and of course SQL. We have our differences when we talk about food or movie but we always agree when we talk about SQL. Yesterday while chatting with him we talked about SQLPASS and the conversation lasted for a long time. Here is the conversation between us on GTalk. I have removed a few of the personal talks and formatted into paragraphs as GTalk often shows stuff out of formatting. Pinal: Sri, Congrats on running for the PASS BoD again. You were so close last year. What made you decide to run again this year? Sri: Thank you Pinal for your leadership in the PASS India Community and all the things you do out there. After coming so close last year, there was no doubt in my mind that I will run again. I was truly humbled by the support I got from the community. Growing up in India for over 25 years, you are brought up in a very competitive part of the world. Right from the pressure of staying in the top of the class from kindergarten to your graduation, the relentless push from your parents about studying and getting good grades (and nothing else matters), you land up essentially living in a pressure cooker. To survive that relentless pressure, you need to have a thick skin, ability to stand up for who you really are , what you want to accomplish and in the process stay true those values. I am striving for a greater cause, to make PASS an organization that can help people with their SQL Server careers, to make PASS relevant to its chapter members, to make PASS an organization that every SQL professional in the world wants to be connected with. Just because I did not get elected or appointed last year does not mean that these causes are not worth fighting. Giving up upon failing the first time is simply not in me. If I did that, what message would I send to those who voted for me? What message would I send to my kids? Pinal: As someone who has such strong roots in India, what can the Indian PASS Community expect from you? Sri: First of all, I think fostering a regional leadership is something PASS must encourage as part of its global growth plan. For PASS global being able to understand all the issues in a region of the world and make sound decisions will be a tough thing to do on a continuous basis. I expect people like you, chapter leaders, regional mentors, MVPs of the region start playing a bigger role in shaping the next generation of PASS. That is something I said in my campaign and I still stand by it. I would like to see growth in the number of chapters in India. The current count does not truly represent the full potential of that region. I was pretty thrilled to see the Bangalore SQLSaturday happen early this year. I would like to see more of SQLSaturday events, at least in the major metro cities. I know the issues in India are very different from the rest of the world. So the formula needs to be tweaked a little for it to work better in India. Once the SQLSaturday model is vetted out, maybe there could be enough justification to have SQLRally India. PASS needs to have a premier SQL event in that region. Going to USA or Europe for that matter is incredibly hard due to VISA issues etc. So this could be a case of where PASS comes closer to where the community is. Pinal: What portfolio would take on if you are elected to the PASS Board? Sri: There are some very strong folks on the PASS Board today. The President discusses the portfolios with the group and makes the final call on the portfolios. I am also a fan of having a team associated with the portfolios. In that case, one person is the primary for a portfolio but secondary on a couple of other portfolios. This way people on the board have a direct vested interest in a few portfolios. Personally, I know I would these portfolios good justice – Chapters, Global Growth and Events (SQLSat, SQLRally). I would try to see if we can get a director to focus on Volunteers.  To me that is very critical for growth in the international regions. Pinal: This is an interesting conversation with you Sri. I know you so long time but this is indeed inspiring to many. India is a big country and we appreciate your thoughts. Sri: Thank you very much for taking time to chat with me today. Cheers. There are pretty strong candidates for SQLPASS Board of Elections this year. I know all of them in person and honestly it is going to be extremely difficult to not to vote for anybody. I am indeed in a crunch right now how to pick one over another. Though the choice is difficult, I encourage you to vote for them. I am extremely confident that the new board of directors will all have the same goal – Better SQL Server Community.

• Old school trick that I forgot

  - by DavidMadden

  If you have to support some older Winforms you might like to remember this.  When opening a MessageBox to display that the user entered incorrect information, if you are doing so from a dialog, catch the DialogResult of the MessageBox and then set  this.DialogResult = DialogResult.None; to prevent the dialog from closing if you want the user to try again.  Otherwise, it will close the dialog box and return to the section of code that called it.Note:  You do not have to catch the DialogResult from the MessageBox.  You can still set this after the return from the call to the MessageBox.  Just make sure to do either but exiting the body of the dialog itself.

• How do you handle very old browsers on your site?

  - by Alex

  Hi. We have a non-profit web site that got about 5 million hits in May. Of those, about 5,700 were from IE 5.x or lower; about 4,000 were from folks with Netscape 4.x or lower. We know that the current site's layout works for newer browsers and we're testing it on IE6 as well (along with Chrome, Opera, Safari, and Firefox). How do you handle the folks with the older browsers? Because of jQuery libraries and such, the pages might not function correctly on those old browsers. Is there an easy way to show a text-only version on browsers that can't handle the CSS and jQuery goodies? How do large sites handle this sort of thing? I've used the @embed to hide the stylesheet from Netscape 4.x, but not sure beyond that.

• ruby nl2br outside <code> ... </code>

  - by Julien P.

  Hi everyone, I've been struggling on this thing for a week without being able to find what I'm looking for. Here is what I'd like to do: I'm setting up a wiki where I can post all my knowledge to (yes, I know a couple things :p) but I can't render it the way I'd like to. The bodies of my posts are text fields. In order to render them the right way I run the following command: @post.body.gsub("\n", "<br />") I also have some tags with some code inside that looks like this < code my code < /code. Here come's the issue. Every line between the < code and < /code tags are changed to but it doesn'r render properly since I'm using a code render template. Therefore, I'd like to know if there is a way to change all \n to < br / except for those between < code and < /code Thank you everyone for reading this and helping me out. PS: Please do not consider the spaces after the < in each tag. I had to do this to "espace" them. Julien

• How should I unit test a code-generator?

  - by jkp

  This is a difficult and open-ended question I know, but I thought I'd throw it to the floor and see if anyone had any interesting suggestions. I have developed a code-generator that takes our python interface to our C++ code (generated via SWIG) and generates code needed to expose this as WebServices. When I developed this code I did it using TDD, but I've found my tests to be brittle as hell. Because each test essentially wanted to verify that for a given bit of input code (which happens to be a C++ header) I'd get a given bit of outputted code I wrote a small engine that reads test definitions from XML input files and generates test cases from these expectations. The problem is I dread going in to modify the code at all. That and the fact that the unit tests themselves are a: complex, and b: brittle. So I'm trying to think of alternative approaches to this problem, and it strikes me I'm perhaps tackling it the wrong way. Maybe I need to focus more on the outcome, IE: does the code I generate actually run and do what I want it to, rather than, does the code look the way I want it to. Has anyone got any experiences of something similar to this they would care to share?

• ASMX Web Service online works when all of the code is in one file without code-behind

  - by Ben McCormack

  I have an ASMX Web Service that has its code entirely in a code-behind file, so that the entire contents of the .asmx file is: <%@ WebService Language="C#" CodeBehind="~/App_Code/AddressValidation.cs" Class="AddressValidation" %> On my test machine (Windows XP with IIS 5), I set up a virtual directory just for this ASP.NET 2.0 solution and everything works great. All my code is separated nicely and it just works. However, when we deployed this solution to our Windows Server 2003 development environment, we noticed that the code only compiled when all of the code was dropped directly into the .asmx file, meaning that the solution didn't work with code-behind. We can't figure out why this is happening. One thing that's different about our setup in our development environment is that instead of creating a separate virual directory just for this solution, we dropped it into an existing directory that runs a classic ASP application. So here we have a folder with an ASP.NET 2.0 application within a directory that contains a classic ASP application. Granted, everything in the ASP.NET 2.0 application works if all of the code is within the .asmx file and not in code-behind, but we'd really like to know why it's not recognizing the code-behind files and compiling it correctly.

• Do you know any code sharing sites?

  - by jasondavis

  I am always looking to organize and make my resource bookmarks better and easiar to access when I need them. 1 thing I really like is code sharing sites, they let you enter in code and then give you a special link to give a friend or a user on this site even to show then code, This is a very useful tool I believe. So below is my list of code sharing sites, there is 4 on the list and they all have unique features. Some have syntax highlighting for multiple languages, some allow you to save your code as private and only share with the people you give the link to, and some even run the run and output any possible errors. Do you know of any sites like this? if you know of any sites like this for programming code please post it here. http://pastie.org/ http://codepad.org/ http://pastebin.me/ http://jsbin.com/ allows you to auto-insert a javascript library like jquery and test live js code

• How do you protect code from leaking outside?

  - by cubex

  Besides open-sourcing your project and legislation, are there ways to prevent, or at least minimize the damages of code leaking outside your company/group? We obviously can't block Internet access (to prevent emailing the code) because programmer's need their references. We also can't block peripheral devices (USB, Firewire, etc.) The code matters most when it has some proprietary algorithms and in-house developed knowledge (as opposed to regular routine code to draw GUIs, connect to databases, etc.), but some applications (like accounting software and CRMs) are just that: complex collections of routine code that are simple to develop in principle, but will take years to write from scratch. This is where leaked code will come in handy to competitors. As far as I see it, preventing leakage relies almost entirely on human process. What do you think? What precautions and measures are you taking? And has code leakage affected you before?

• How to Format Code in Research Reports

  - by RoseOfJericho

  I am currently writing a formal research report, and I'll be including code with this report. Question: Is there an accepted way of displaying code in research reports? I'm thinking both in terms of font, spacing, et cetera, and whether the code should be displayed inside the document, or in an appendix. The code will be JavaScript and PHP. None of the sections of code will be more than 25 lines (so they're mere snippets). There will be approx. half a dozen snippets. Each of the snippets will have a couple of paragraphs explaining what is happening in the code, and a discussion on its pros/cons. I have no contact with the body the report will be submitted to, and they have no published guidelines on how to format code (please do not question these points). Any help considered and appreciated.

• Getting ROBOCOPY to return a "proper" exit code?

  - by Lasse V. Karlsen

  Is it possible to ask ROBOCOPY to exit with an exit code that indicates success or failure? I am using ROBOCOPY as part of my TeamCity build configurations, and having to add a step to just silence the exit code from ROBOCOPY seems silly to me. Basically, I have added this: EXIT /B 0 to the script that is being run. However, this of course masks any real problems that ROBOCOPY would return. Basically, I would like to have exit codes of 0 for SUCCESS and non-zero for FAILURE instead of the bit-mask that ROBOCOPY returns now. Or, if I can't have that, is there a simple sequence of batch commands that would translate the bit-mask of ROBOCOPY to a similar value?

• Apple Automator "New PDF from Images" maintaining same filename

  - by mech

  I will potentially have 26k of old legacy PICT images to transfer first to PDF for migration. I am using Apple Automator and also the "Dispense Items Incrementally" to loop through it. However, I can't seem to let "New PDF from Images" to remember the original filename. Anyone able to offer some advice :) FYI, I am transforming it to PDF because I can't do it using ImageMagick to convert directly to my ultimate JPEG format. Due to the fact that my PICT was created very long ago and thus has some convert: improper image header error. See this ticket for more information. Thus I am doing a intermediate convert PICT to PDF first, then convert that PDF to JPEG :) The only thing left is the naming of the "Output File Name" which do not allow me to identify original filename. See the screen here:

• How to share malicious source code?

  - by darma

  I have a client whose site (not one i developed) is infected by a trojan/malicious code. I have asked him to send me the dirty files in a zip but either gmail or unzipping is blocking them. I've tried text files and word files, and i'm suspecting many different file types will be blocked the same way, either by my mail client, anti-malware software, browser etc. (which is normal). Do you know a way he could share those lines so i can read them and do some research about the malicious source code? An image/screenshot of his text editor would be an idea but the files are long + i'd prefer to be able to copy/paste from them. Thank you!

• Cannot use Alt code for Unicode character insertion any more

  - by Bergi

  I've been using the Alt code for the ellipsis, 8230, for some time now, in several applications. A few days ago it stopped working, and & is displayed instead of … when pressing Alt+8+2+3+0 (on numpad). This happened both on my desktop and on my laptop (where I use it with Fn). Both run on 64bit-Win-7 with code page 850, and both might have recently updated Windows and Opera 12. What could be the reason this input method got disabled, and how do I switch it back? Btw, I just found out that Alt+0+1+3+3 does work.

• How can I learn to effectively write Pythonic code?

  - by Matt Fenwick

  I'm tired of getting downvoted and/or semi-rude comments on my Python answers, saying things like "this isn't Pythonic" or "that's not the Python way of doing things". To clarify, I'm not tired of getting corrected and downvoted, and I'm not tired of being wrong: I'm tired of feeling like there's a whole field of Python that I know nothing about, and seems to be implicit knowledge of experienced Python programmers. Doing a google search for "Pythonic" reveals a wide range of interpretations. The wikipedia page says: A common neologism in the Python community is pythonic, which can have a wide range of meanings related to program style. To say that code is pythonic is to say that it uses Python idioms well, that it is natural or shows fluency in the language. Likewise, to say of an interface or language feature that it is pythonic is to say that it works well with Python idioms, that its use meshes well with the rest of the language. It also discusses the term "unpythonic": In contrast, a mark of unpythonic code is that it attempts to write C++ (or Lisp, Perl, or Java) code in Python—that is, provides a rough transcription rather than an idiomatic translation of forms from another language. The concept of pythonicity is tightly bound to Python's minimalist philosophy of readability and avoiding the "there's more than one way to do it" approach. Unreadable code or incomprehensible idioms are unpythonic. I suspect one way to learn the Pythonic way is just to program in Python a whole bunch. But I bet I could write a bunch of crap and not improve that much without some guidance, whereas a good resource might speed up the learning process significantly. PEP 8 might be exactly what I'm looking for, or maybe not. I'm not sure; on the one hand it covers a lot of ground, but on the other hand, I feel like it's more suited as a reference for knowledgeable programmers than a tutorial for fresh 'uns. How do I get my foot in the Pythonic/Python way of doing things door?

• What is the best approach for inline code comments?

  - by d1egoaz

  We are doing some refactoring to a 20 years old legacy codebase, and I'm having a discussion with my colleague about the comments format in the code (plsql, java). There is no a default format for comments, but in most cases people do something like this in the comment: // date (year, year-month, yyyy-mm-dd, dd/mm/yyyy), (author id, author name, author nickname) and comment the proposed format for future and past comments that I want is: // {yyyy-mm-dd}, unique_author_company_id, comment My colleague says that we only need the comment, and must reformat all past and future comments to this format: // comment My arguments: I say for maintenance reasons, it's important to know when and who did a change (even this information is in the SCM). The code is living, and for that reason has a history. Because without the change dates it's impossible to know when a change was introduced without open the SCM tool and search in the long object history. because the author is very important, a change of authors is more credible than a change of authory Agility reasons, no need to open and navigate through the SCM tool people would be more afraid to change something that someone did 15 years ago, than something that was recently created or changed. etc. My colleague's arguments: The history is in the SCM Developers must not be aware of the history of the code directly in the code Packages gets 15k lines long and unstructured comments make these packages harder to understand What do you think is the best approach? Or do you have a better approach to solve this problem?

• How should I describe the process of learning someone else's code? (In an invoicing situation.)

  - by MattyG

  I have a contract to upgrade some in-house software for a large company. The company has requested multiple feature additions and a few bug fixes. This is my first freelance style job. First, I needed to become familiar with how the application worked - I learnt it as if I was a user. Next, I had to learn how the software worked. I started with broad concepts, and then narrowed down into necessary detail before working on each bug fix and feature. At least at the start of the project, it took me a lot longer to learn the existing code than it did to write the additional features. How can I describe the process of learning the existing code on the invoice? (This part of the company usually does things in-house, so doesn't have much experience dealing with software contractors like me, and I fear they may not understand the overhead of learning someone else's code). I don't want to just tack the learning time onto the actual feature upgrade, because in some cases this would make a 'simple task' look like it took me way too long. I want break the invoice into relevant steps, and communicate that I'm charging for the large overhead of learning someone else's code before being able to add my own to it. Is there a standard way of describing this sort of activity when billing for a job?

• How to introduce a computer illiterate 50-year old to programming [closed]

  - by sunday

  The other day my dad asked me a question that I would have never expected from him. "How can I learn C++?" My dad is turning 56 this year and computers are a distant concept for him. He doesn't know how to use a phone very well besides calling numbers (no speed dial or contacts); though he has started to learn computers a little better - to the point that he knows how to open the internet (in Windows) and browse around (and has successfully completed several job applications entirely on his own online, of which he was offered positions too). But still, these are too narrow-windowed experiences to mean much, really. While he may not have the background, my dad knows how to read. And I mean reading as a skill, not just an ability. He has little to no college education (financial problems, family, etc.) and was fortunate enough to finish high school, but still taught himself to become a master electrician and has been one for almost 30 years now. He did the same with guitar, learning to play at a very professional level and has been praised for his skill. In high school, he picked up a weight lifting book - and was the only person in his high school at the time to qualify officially as an "athlete" by national standards. In all cases, he just needed something to read. Something to teach him. He absorbs information like a sponge. I have no doubt in my dad's motivation or capability of doing this, so my general goal is simply: Get my dad into the world of computers, and get him on the road to programming. I strongly believe that once I get him through the fundamentals, his drive and reading skill will keep him going on this own. So I'm asking you all: where should I start with all this? And what are the best resources out there? Should I get him to start Linux instead of Windows? Is C++ a bad idea? Remember, he needs to (IMO) learn computers first, and then get that first grasp (the "Hello world" experience) of programming. For money's sake and at top preference, I'd like free online resources that he can read, but by all means any good suggestions in print or paid-for-online are welcome (that I could possibly look into later to purchase). And also, I intend to start him off with C++ (no Python, Java, etc.), because I know it the best and will be able to help him along the way with code. (I have minimal knowledge right now in other languages). Edit: I'm getting a lot of persistent suggestions to use Python. The only reason I wanted to do C++ is that I KNOW it and can be THERE when my dad needs help. My VERY FIRST exposure to programming ever was Java. I learned Java, and I got good at it. I open to other suggestions, but please provide an effective application of your suggestions. EDIT #2: I understand my approach/thinking/knowledge could be lacking here. I'm a sophomore level undergraduate CS major. If you don't agree with anything in my post, tell me why - give me ideas, information - that's why I'm asking in the first place. To narrow down my general goal to specific reachable goals.

• Unit Testing - not testable code converted to testable code

  - by imak

  I have read so many places is that if your code is not test-able that mean code is not well written. So that makes me start writing a code that is test-able and to start using some unit testing framework. With this though I start looking for some example with piece of code that is not testable and gradually converted to a testable code. I find tons of examples on unit testing but if someone can provide an example like above it probably can jump start things for me. TIA

• How to train yourself to avoid writing “clever” code?

  - by Dan Abramov

  Do you know that feeling when you just need to show off that new trick with Expressions or generalize three different procedures? This does not have to be on Architecture Astronaut scale and in fact may be helpful but I can't help but notice someone else would implement the same class or package in a more clear, straightforward (and sometimes boring) manner. I noticed I often design programs by oversolving the problem, sometimes deliberately and sometimes out of boredom. In either case, I usually honestly believe my solution is crystal clear and elegant, until I see evidence to the contrary but it's usually too late. There is also a part of me that prefers undocumented assumptions to code duplication, and cleverness to simplicity. What can I do to resist the urge to write “cleverish” code and when should the bell ring that I am Doing It Wrong? The problem is getting even more pushing as I'm now working with a team of experienced developers, and sometimes my attempts at writing smart code seem foolish even to myself after time dispels the illusion of elegance.

• Are there code reviews in opensource projects? If so, what tools are used to do this?

  - by monksy

  I know there is a big push for code reviews in commercial development. However, are code reviews used in open source software or is based on trust? If so, then how are they performed? [Is it a delayed commit, "a pre commit environment", is there a tool that allows for the patch to be sent to another dev]? Are there any projects that use code reviews? From my understanding the linux kernel is mostly based around trust of the commitor. MySQL was based on the main author's approval and the performance impact.

• Being prepared for a code review as a developer?

  - by Karthik Sreenivasan

  I am looking for some ideas here. I read the article How should code reviews be Carried Out and Code Reviews, what are the advantages? which were very informative but I still need more clarity on the question below. My Question is, Being the target developer, can you suggest some best practices a developer can incorporate before his code is going get reviewed. Currently I practice the following methods PPT for a logical flow Detailed comments. Issue: Even though I have implemented the above practices, they do not help on the review. The problem I faced is, when certain logic is referred, I keep searching for the implementation and the flow and too much time is wasted in the process and I get on people’s nerve. I think a lot of developers would be going through what I am going through as well.

• Should companies require developers to credit code they didn't write?

  - by sunpech

  In academia, it's considered cheating if a student copies code/work from someone/somewhere else without giving credit, and tries to pass it off as his/her own. Should companies make it a requirement for developers to properly credit all non-trivial code and work that they did not produce themselves? Is it useful to do so, or is it simply overkill? I understand there are various free licenses out there, but if I find stuff I like and actually use, I really feel compelled to give credit via comment in code even if it's not required by the license (or lack thereof one).

• New code base, what experiences/recommendations do you have?

  - by hlovdal

  I will later this year start on a project (embedded hardware, C, small company) where I believe that most (if not all) code will be new. So what experiences do you have to share as advice to starting a new code base? What have you been missing in projects that you have been working on? What has worked really well? What has not worked? Let's limit this question to be about things that relate directly to the code (e.g "banning the use of gets()": in scope, version control: border line, build system: out of scope).

• How do you cope with ugly code that you wrote?

  - by Ralph

  So your client asks you to write some code, so you do. He then changes the specs on you, as expected, and you diligently implement his new features like a good little lad. Except... the new features kind of conflict with the old features, so now your code is a mess. You really want to go back and fix it, but he keeps requesting new things and every time you finish cleaning something, it winds up a mess again. What do you do? Stop being an OCD maniac and just accept that your code is going to wind up a mess no matter what you do, and just keep tacking on features to this monstrosity? Save the cleaning for version 2?
