  • Would you use UML if it kept stakeholders from requesting changes frequently?

    - by Huperniketes
    As much as programmers hate to document their code/system and draw UML (especially, Sequencing, Activity and State machine diagrams) or other diagramming notation, would you agree to do it if it kept managers from requesting a "minor change" every couple of weeks? IOW, would you put together visual models to document the system if it helped you demonstrate to managers what the effect of changes are and why it takes so long to implement them? (Edited to help programmers understand what type of answer I'm looking for.) 2nd edit: Restating my question again, "Would you be willing to use some diagramming notation, against your better nature as a programmer, if it helped you manage change requests?" This question isn't asking if there might be something wrong with the process. It's a given that there's something wrong with the process. Would you be willing to do more work to improve it?

  • SQL Server Manageability Series: how to change the default path of .cache files of a data collector? #sql #mdw #dba

    - by ssqa.net
    How to change the default path of .cache files of a data collector after the Management Data Warehouse (MDW has been setup? This was the question asked by one of the DBAs in a client's place, instantly I enquired that were there any folder specified while setting up the MDW and obvious answer was no as there were left default. This means all the .CACHE files are stored under %C\TEMP directory which may post out of disk space problem on the server where the MDW is setup to collect. Going back...(read more)

  • 10gR2 Transportable Tablespaces Certified for EBS 11i

    - by Steven Chan
    Database migration across platforms of different "endian" (byte ordering) formats using the Cross Platform Transportable Tablespaces (XTTS) process is now certified for Oracle E-Business Suite Release 11i (11.5.10.2) with Oracle Database 10g Release 2.  This process is sometimes also referred to as transportable tablespaces (TTS).What is the Cross-Platform Transportable Tablespace Feature?The Cross-Platform Transportable Tablespace feature allows users to move a user tablespace across Oracle databases. It's an efficient way to move bulk data between databases. If the source platform and the target platform are of different endianness, then an additional conversion step must be done on either the source or target platform to convert the tablespace being transported to the target format. If they are of the same endianness, then no conversion is necessary and tablespaces can be transported as if they were on the same platform.Moving data using transportable tablespaces can be much faster than performing either an export/import or unload/load of the same data. This is because transporting a tablespace only requires the copying of datafiles from source to the destination and then integrating the tablespace structural information. You can also use transportable tablespaces to move both table and index data, thereby avoiding the index rebuilds you would have to perform when importing or loading table data.

  • Is '@' Error Suppression a Valid Technique for Testing for an Optional Array Key?

    - by MikeSchinkel
    Rarst and I were debating offline about the use of the '@' error suppression operator in PHP, specifically for use to test for existence of "optional" array keys, i.e. array keys that are being used as a switch here a their lack of existence in the array is functionally equivalent to the array having the key with a value equaling false. Here is pseudo-code for this scenario: function do_something( $args = array() ) { if ( @$args['switch'] ) { // Do something with this switch } // continue on... } vs. this approach: function do_something( $args = array() ) { if ( ! empty( $args['switch'] ) && $args['switch'] ) { // Do something with this switch } // continue on... } Of course in most use-cases, suppressing errors would not be A Good Thing(tm). However in this use-case where an array is passed with an optional element, it seems to me that it is actually a very good technique but I could be wrong and would like to hear other's opinions on the subject before I make up my mind. I do know that there are alleged performance hits for using the former approach but I'd like to know how they compare with the alternative and if they performance hits really matter in real world scenarios? P.S. I decided to post this because, after debating this offline with Rarst, he asked a more general question here on Programmers but didn't actually give a detailed example of the specific use-case we were debating. And since I'm pretty sure he'll want to use the out-of-context answers on that other question as justification for why the above is "bad" I decided I needed to get opinions on this specific use-case.

  • Should I provide fallbacks for HTML5/CSS3 elements in a web page at this point?

    - by Abluescarab
    I'm wondering if I should bother providing a fallback for HTML5 tags and attributes and CSS3 styling at this point in time. I know that there's probably still a lot of people out there who use older versions of browsers and HTML5/CSS3 are still fairly new. I read this article: Should I use non-standard tags in a HTML page for highlighting words? and one answer mentioned that people kind of "cheat" with older browsers by using the new tags and attributes, but styling them in CSS to ensure they show up right. This question: Relevance of HTML5: Is now the time? was asked about two years ago and I don't know how relevant it is anymore. For example, I want to use the placeholder and required attributes in a web form I'm building and it has no labels to show what each <input> is. How do I handle this, or do I bother?

  • Choosing a subject to create a site for

    - by Daniel
    For 6 years I'm working as web developer and I would like to finally create my own site. I thought I have everything needed: programming and administration skills, found a good designer, own servers and understanding how to operate site. But I've missed very important (or the most important) point: how do I find a subject for my site? My hobby and my work are the same: IT, but I don't want to create just another tech blog or news aggregator, I want something different. First I thought things like Google Trends or Google top 1000 could help, but I've got lost in thousands of options I can't see them all (I actually can, but it'll take at least a couple of month). So my question is: how did you start? Where did you get the idea?

  • programming manner to solve problem

    - by gcc
    Everyone has style(s)/technique(s) to approach/solve real world problems. This/these technique(s) distinguish(es) us from other people or other programmers. (Actually, I think it make us a wanted/ great programmer/computer science ) To improve, we read a lot of books (ex : programming style, how to solve program, how to approach problem, software and algorithm). Can I learn your technique? In other words, if someone gives you a problem, at first step, what are you doing to solve it? (In all honesty, I want learn in what manner you are looking problem )

  • Is it good to review programs with seniors and boss even if it is working fine?

    - by Himanshu
    In my company, before delivery of any project, my boss asks my seniors to review programs written by me or other team members or sometimes boss also sits with us for review. I think it is a good way of getting knowledge, but sometimes when programs are working fine, they don't work same after review and I need to look again into my program. They says that review helps to optimize program and query execution, but can we prefer optimization over actual functioning of program?

  • Is it a bad idea to list every function/method argument on a new line and why?

    - by dgnball
    I work with someone who, every time they call a function they put the arguments on a new line e.g. aFunction( byte1, short1, int1, int2, int3, int4, int5 ) ; I find this very annoying as it means the code isn't very compact, so I have to scan up and down more to actually make any sense of the logic. I'm interested to know whether this is actually bad practice and if so, how can I persuade them not to do it?

  • Stuff you should have learned in school but didn't pay attention to at the time

    - by HLGEM
    This question made me think that there was a better question to ask. What did you learn in school that you didn't care about at the time, but turned out to be useful or you had to relearn in the workplace because you had it in school, but didn't retain the information and you needed it? (I mean for software related jobs.) I think this might help college students identify some of what they really should be paying attention to while they are in school.

  • Default values - are they good or evil?

    - by Andrew
    The question about default values in general - default return function values, default parameter values, default logic for when something is missing, default logic for handling exceptions, default logic for handling the edge conditions etc. For a long time I considered default values to be a "pure evil" thing, something that "cloaks the catastrophe" and results in a very hard do find bugs. But recently I started to think about default values as some sort of a technical debt ... which is not a straight bad thing but something that could provide some "short term financing" get us to survive the project (how many of us could afford to buy a house without taking out the mortgage?). When I say a "short term" - I don't mean - "do something quickly first and do refactor it out later before it hits the production". No - I am talking about relying on a hardcoded default values in a production software. Granted - it could cause some issues, but what if it only going to cause a single trouble in a whole year. Again - I am talking about the "average" mainstream software here (not a software for a nuclear power station) - the average web site or a UI application for the accounting software, meaning that people lives are not at stake, nor millions of dollars. Again, from my experience, business users would rather live with the software which "works somehow", rather then wait for a perfect one. And the use of default values helps a lot if you develop a software in a RAD style. But again - the longest debug sessions I have spent were because of the bugs introduced by a default value which either stopped being "a default" along the way or because a small subsystem has recently been upgraded and as a result of this upgrade it does not handle the default correctly (e.g. empty list vs null, or null string vs empty string). So my question is - are the default values good or evil. And if they are a technical debt - how do measure up how much you can borrow so you can afford the repayments? Would really appreciate any input. Cheers. EDIT: If I am using the default values as a way to cut the corners during the development - and if the corners cutting results in a bugs and issues - what is the methodology to recover from these issues?

  • Why do I need two Instances in Windows Azure?

    - by BuckWoody
    Windows Azure as a Platform as a Service (PaaS) means that there are various components you can use in it to solve a problem: Compute “Roles” - Computers running an OS and optionally IIS - you can have more than one "Instance" of a given Role Storage - Blobs, Tables and Queues for Storage Other Services - Things like the Service Bus, Azure Connection Services, SQL Azure and Caching It’s important to understand that some of these services are Stateless and others maintain State. Stateless means (at least in this case) that a system might disappear from one physical location and appear elsewhere. You can think of this as a cashier at the front of a store. If you’re in line, a cashier might take his break, and another person might replace him. As long as the order proceeds, you as the customer aren’t really affected except for the few seconds it takes to change them out. The cashier function in this example is stateless. The Compute Role Instances in Windows Azure are Stateless. To upgrade hardware, because of a fault or many other reasons, a Compute Role's Instance might stop on one physical server, and another will pick it up. This is done through the controlling fabric that Windows Azure uses to manage the systems. It’s important to note that storage in Azure does maintain State. Your data will not simply disappear - it is maintained - in fact, it’s maintained three times in a single datacenter and all those copies are replicated to another for safety. Going back to our example, storage is similar to the cash register itself. Even though a cashier leaves, the record of your payment is maintained. So if a Compute Role Instance can disappear and re-appear, the things running on that first Instance would stop working. If you wrote your code in a Stateless way, then another Role Instance simply re-starts that transaction and keeps working, just like the other cashier in the example. But if you only have one Instance of a Role, then when the Role Instance is re-started, or when you need to upgrade your own code, you can face downtime, since there’s only one. That means you should deploy at least two of each Role Instance not only for scale to handle load, but so that the first “cashier” has someone to replace them when they disappear. It’s not just a good idea - to gain the Service Level Agreement (SLA) for our uptime in Azure it’s a requirement. We point this out right in the Management Portal when you deploy the application: (Click to enlarge) When you deploy a Role Instance you can also set the “Upgrade Domain”. Placing Roles on separate Upgrade Domains means that you have a continuous service whenever you upgrade (more on upgrades in another post) - the process looks like this for two Roles. This example covers the scenario for upgrade, so you have four roles total - One Web and one Worker running the "older" code, and one of each running the new code. In all those Roles you want at least two instances, and this example shows that you're covered for High Availability and upgrade paths: The take-away is this - always plan for forward-facing Roles to have at least two copies. For Worker Roles that do background processing, there are ways to architect around this number, but it does affect the SLA if you have only one.

  • Naming: objectAction or actionObject?

    - by DocSalvage
    The question, Stored procedure Naming conventions?, and Joel's excellent Making Wrong Code Look Wrong article come closest to addressing my question, but I'm looking for a more general set of criteria to use in deciding how to name modules containing code (classes, objects, methods, functions, widgets, or whatever). English (my only human language) is structured as action-object (i.e closeFile, openFile, saveFile) and since almost all computer languages are based on English, this is the most common convention. However, in trying to keep related code close together and still be able to find things, I've found object-action (i.e. fileClose, fileOpen, fileSave) to be very attractive. Quite a number of non-English human languages follow this structure as well. I doubt that one form is universally superior, but when should each be used in the pursuit of helping to make sure bad code looks bad?

  • Grading an algorithm: Readability vs. Compactness

    - by amiregelz
    Consider the following question in a test \ interview: Implement the strcpy() function in C: void strcpy(char *destination, char *source); The strcpy function copies the C string pointed by source into the array pointed by destination, including the terminating null character. Assume that the size of the array pointed by destination is long enough to contain the same C string as source, and does not overlap in memory with source. Say you were the tester, how would you grade the following answers to this question? 1) void strcpy(char *destination, char *source) { while (*source != '\0') { *destination = *source; source++; destionation++; } *destionation = *source; } 2) void strcpy(char *destination, char *source) { while (*(destination++) = *(source++)) ; } The first implementation is straightforward - it is readable and programmer-friendly. The second implementation is shorter (one line of code) but less programmer-friendly; it's not so easy to understand the way this code is working, and if you're not familiar with the priorities in this code then it's a problem. I'm wondering if the first answer would show more complexity and more advanced thinking, in the tester's eyes, even though both algorithms behave the same, and although code readability is considered to be more important than code compactness. It seems to me that since making an algorithm this compact is more difficult to implement, it will show a higher level of thinking as an answer in a test. However, it is also possible that a tester would consider the first answer not good because it's not readable. I would also like to mention that this is not specific to this example, but general for code readability vs. compactness when implementing an algorithm, specifically in tests \ interviews.

  • How can a solo programmer become a good team player?

    - by Nick
    I've been programming (obsessively) since I was 12. I am fairly knowledgeable across the spectrum of languages out there, from assembly, to C++, to Javascript, to Haskell, Lisp, and Qi. But all of my projects have been by myself. I got my degree in chemical engineering, not CS or computer engineering, but for the first time this fall I'll be working on a large programming project with other people, and I have no clue how to prepare. I've been using Windows all of my life, but this project is going to be very unix-y, so I purchased a Mac recently in the hopes of familiarizing myself with the environment. I was fortunate to participate in a hackathon with some friends this past year -- both CS majors -- and excitingly enough, we won. But I realized as I worked with them that their workflow was very different from mine. They used Git for version control. I had never used it at the time, but I've since learned all that I can about it. They also used a lot of frameworks and libraries. I had to learn what Rails was pretty much overnight for the hackathon (on the other hand, they didn't know what lexical scoping or closures were). All of our code worked well, but they didn't understand mine, and I didn't understand theirs. I hear references to things that real programmers do on a daily basis -- unit testing, code reviews, but I only have the vaguest sense of what these are. I normally don't have many bugs in my little projects, so I have never needed a bug tracking system or tests for them. And the last thing is that it takes me a long time to understand other people's code. Variable naming conventions (that vary with each new language) are difficult (__mzkwpSomRidicAbbrev), and I find the loose coupling difficult. That's not to say I don't loosely couple things -- I think I'm quite good at it for my own work, but when I download something like the Linux kernel or the Chromium source code to look at it, I spend hours trying to figure out how all of these oddly named directories and files connect. It's a programming sin to reinvent the wheel, but I often find it's just quicker to write up the functionality myself than to spend hours dissecting some library. Obviously, people who do this for a living don't have these problems, and I'll need to get to that point myself. Question: What are some steps that I can take to begin "integrating" with everyone else? Thanks!

  • How to handle compensation issue

    - by Ali
    I consider myself an expert Software Developer. Recently, I noticed my current company posted a new job through a recruting firm requiring half experience than I have and even lesser set of skills. However, they are offering the same salary as my current salary. When I joined my current company a year ago, they declined to pay my asking salary. My evaluations are good and there are critical projects in the pipeline where my involvement is crucial for their success. I'm little confused on how to handle this situation. I don't want to come across threatning or any thing like that.

  • HTML5 article tag application for the iPad/iPhone

    - by dspencer
    I've used article tags on websites. My understanding and practice is to use the article tag for publication content. I always use HTML/HTML5 tags as their intended purposes and not at will. Recently, I've seen an HTML template that uses the article tag for the non-publication page content such as the content of an About Us page or any other generic page. I asked the why it was used this way and the (vague) explanation was that it had to do with the way the iPad read the tag. Is this true?

Servers hosting Oracle products which are clients of an NTP server (Network Time Protocol) may be particularly susceptible to this issue as the NTP server is updated. Linux distributions which may be affected include Oracle Enterprise Linux, Red Hat Enterprise Linux, Oracle VM and Oracle Unbreakable Enterprise Kernel. Asianux 2 and 3, based on RHEL 4 and 5, may also be affected. One report of correction to high agent CPU using Note 1472421.1 on SLES11 has also been reported. Not all customers will be affected, but those, who are affected, may observe higher than normal CPU consumption on their Linux environments where JVM's are utilized.  In Oracle Enterprise Manager ( EM ) , this problem can manifest itself as high CPU consumption with the EM Agent process (which runs on a JVM in EM 12c, for instance).  It is possible that the OMS is also affected. We would advise customers to review the description of this problem in MOS Note 1472651.1 and take action if they observe that their environment is affected.

  • How do you author code

    - by garbagecollector
    This is something I was never taught. I have seen alot of different types of authoring styles. I code primarily in Java and Python. I was wondering if there was a standard authoring style or if everything is freestyle. Also if you answer would you mind attaching the style you use to author files that your create at home or at work. I usually just go @author garbagecollector @company garbage inc.

  • Maintainability of Boolean logic - Is nesting if statements needed?

    - by Vaccano
    Which of these is better for maintainability? if (byteArrayVariable != null) if (byteArrayVariable .Length != 0) //Do something with byteArrayVariable OR if ((byteArrayVariable != null) && (byteArrayVariable.Length != 0)) //Do something with byteArrayVariable I prefer reading and writing the second, but I recall reading in code complete that doing things like that is bad for maintainability. This is because you are relying on the language to not evaluate the second part of the if if the first part is false and not all languages do that. (The second part will throw an exception if evaluated with a null byteArrayVariable.) I don't know if that is really something to worry about or not, and I would like general feedback on the question. Thanks.

  • Use Those Schemas, People!

    - by BuckWoody
    Database Schemas are just containers – they aren’t users or anything else – think of a sub-directory on the hard drive. In early versions of SQL Server we “hid” schemas, placing all objects under “dbo”, which gave the erroneous perception that Schemas are users. In SQL Server 2005, we “un-hid” or re-introduced schemas within the database. Users can have a default schema (a place where their new objects go), you can add new schemas and transfer objects between them, and they have many other benefits. But I still see a lot of applications, developed by shops I know as well as vendors, that don’t make use of a Schema. Everything is piled under dbo. I completely understand this – since permissions can be granted to a schema, they feel a lot like a user, so it’s just easier not to worry about both users and schemas when you create a database. But if you’ll use them properly you can make your application more understandable and portable. You should at least take a few minutes and read more about them – you owe it to your users: http://msdn.microsoft.com/en-us/library/ms190387.aspx Share this post: email it! | bookmark it! | digg it! | reddit! | kick it! | live it!

  • Is it a good pattern that no objects should know more than what it needs to know?

    - by Jim Thio
    I am implementing a viewController class. The view controller class got NSNotification when the Grabbing class start or finish updating. I have 2 choices. I can make the grabbing class to provide a public read only property so all other classes can know whether it is still uploading. Or I can let view Controller to listen to 2 different events. Start updating and finish updating events. The truth is the viewController do need to know whether the grabbing class is still updating or not at any other time. So I am thinking of creating 2 events would be a better way to go. Actually, what do you think?

  • Is it good practice to use functions just to centralize common code?

    - by EpsilonVector
    I run across this problem a lot. For example, I currently write a read function and a write function, and they both check if buf is a NULL pointer and that the mode variable is within certain boundaries. This is code duplication. This can be solved by moving it into its own function. But should I? This will be a pretty anemic function (doesn't do much), rather localized (so not general purpose), and doesn't stand well on its own (can't figure out what you need it for unless you see where it is used). Another option is to use a macro, but I want to talk about functions in this post. So, should you use a function for something like this? What are the pros and cons?

  • Implementing Service Level Agreements in Enterprise Manager 12c for Oracle Packaged Applications

    - by Anand Akela
    Contributed by Eunjoo Lee, Product Manager, Oracle Enterprise Manager. Service Level Management, or SLM, is a key tool in the proactive management of any Oracle Packaged Application (e.g., E-Business Suite, Siebel, PeopleSoft, JD Edwards E1, Fusion Apps, etc.). The benefits of SLM are that administrators can utilize representative Application transactions, which are constantly and automatically running behind the scenes, to verify that all of the key application and technology components of an Application are available and performing to expectations. A single transaction can verify the availability and performance of the underlying Application Tech Stack in a much more efficient manner than by monitoring the same underlying targets individually. In this article, we’ll be demonstrating SLM using Siebel Applications, but the same tools and processes apply to any of the Package Applications mentioned above. In this demonstration, we will log into the Siebel Application, navigate to the Contacts View, update a contact phone record, and then log-out. This transaction exposes availability and performance metrics of multiple Siebel Servers, multiple Components and Component Groups, and the Siebel Database - in a single unified manner. We can then monitor and manage these transactions like any other target in EM 12c, including placing pro-active alerts on them if the transaction is either unavailable or is not performing to required levels. The first step in the SLM process is recording the Siebel transaction. The following screenwatch demonstrates how to record Siebel transaction using an EM tool called “OpenScript”. A completed recording is called a “Synthetic Transaction”. The second step in the SLM process is uploading the Synthetic Transaction into EM 12c, and creating Generic Service Tests. We can create a Generic Service Test to execute our synthetic transactions at regular intervals to evaluate the performance of various business flows. As these transactions are running periodically, it is possible to monitor the performance of the Siebel Application by evaluating the performance of the synthetic transactions. The process of creating a Generic Service Test is detailed in the next screenwatch. EM 12c provides a guided workflow for all of the key creation steps, including configuring the Service Test, uploading of the Synthetic Test, determining the frequency of the Service Test, establishing beacons, and selecting performance and usage metrics, just to name a few. The third and final step in the SLM process is the creation of Service Level Agreements (SLA). Service Level Agreements allow Administrators to utilize the previously created Service Tests to specify expected service levels for Application availability, performance, and usage. SLAs can be created for different time periods and for different Service Tests. This last screenwatch demonstrates the process of creating an SLA, as well as highlights the Dashboards and Reports that Administrators can use to monitor Service Test results. Hopefully, this article provides you with a good start point for creating Service Level Agreements for your E-Business Suite, Siebel, PeopleSoft, JD Edwards E1, or Fusion Applications. Enterprise Manager Cloud Control 12c, with the Application Management Suites, represents a quick and easy way to implement Service Level Management capabilities at customer sites.
