  • Will my self-taught code be fine, or should I take it to the professional level?

    - by G1i1ch
    Lately I've been getting professional work, hanging out with other programmers, and making friends in the industry. The only thing is I'm 100% self-taught. It's caused my style to extremely deviate from the style of those that are properly trained. It's the techniques and organization of my code that's different. It's a mixture of several things I do. I tend to blend several programming paradigms together. Like Functional and OO. I lean to the Functional side more than OO, but I see the use of OO when something would make more sense as an abstract entity. Like a game object. Next I also go the simple route when doing something. When in contrast, it seems like sometimes the code I see from professional programmers is complicated for the sake of it! I use lots of closures. And lastly, I'm not the best commenter. I find it easier just to read through my code than reading the comment. And most cases I just end up reading the code even if there are comments. Plus I've been told that, because of how simply I write my code, it's very easy to read it. I hear professionally trained programmers go on and on about things like unit tests. Something I've never used before so I haven't even the faintest idea of what they are or how they work. Lots and lots of underscores "_", which aren't really my taste. Most of the techniques I use are straight from me, or a few books I've read. Don't know anything about MVC, I've heard a lot about it though with things like backbone.js. I think it's a way to organize an application. It just confuses me though because by now I've made my own organizational structures. It's a bit of a pain. I can't use template applications at all when learning something new like with Ubuntu's Quickly. I have trouble understanding code that I can tell is from someone trained. Complete OO programming really leaves a bad taste in my mouth, yet that seems to be what EVERYONE else is strictly using. It's left me not that confident in the look of my code, or wondering whether I'll cause sparks when joining a company or maybe contributing to open source projects. In fact I'm rather scared of the fact that people will eventually be checking out my code. Is this just something normal any programmer goes through or should I really look to change up my techniques?

  • Surface RT–first impressions

    - by DigiMortal
    Couple months ago I bought Surface RT because I needed some lightweight business supporting thing to take with me sometimes. Carrying ~3kg development laptop is not always fun, specially when you have long days and you need to move from one place to another often. Surface RT turned out to be pretty good investment and here are my first real-life experiences. Read more from my new blog @ gunnarpeipman.com

  • Developer Compensation System

    - by Graviton
    Joel wrote excellent articles on developer compensation system used at Fogcreek. As a team lead and business owner, I would like to device a system that would work best for my team. And here's the catch: I have no experience in managing a team before, and I don't know what works and what doesn't. So I would like to get as many references as I can on this matter. Is there other developer compensation systems that you find is working for you and your company?

  • Tablets Running IDEs

    - by Seth P.
    I am new to the tablet market, but i am trying to learn more. Are any current tablets capable of running programming software such as Visual Studio? I understand they'd have to come up with some kind of streamlined version, but I can imagine the programmers out there excited about the possibility. Does anything like that already exist, or are there rumors of it being available in the near future? Thanks, Seth

    I own a website which is regarding startups and finance. I am looking forward to work on Wordpress programming in which I would be selling wordpress themes. I thought of buying a domain name for Wordpress website but it takes quite lot of time to setup a website and then do its SEO. Is it fine(in terms of SEO and professionalism) to put the Wordpress category inside my old domain like, Domain: www.startupsandfinance.com Wordpress domain, www.wp.startupsandfinance.com

At first, all pupils got to know Oracle as an enterprise with it’s different departments and it’s particular „business language“. What is hardware and software? Why do companies need a database? Questions as such were tailored and simply illustrated by 13 colleagues from the areas of Sales, Sales Consulting, Support and Recruitment.   Followed by a short introduction about career paths from our female colleagues and their respective departments, the girls decided, according to their interests, which business area they would like to get more insights from. Based on their decision the groups were set up and the girls than discovered the work places. This helped everyone to dive deep into the everyday work life, how the offices are structured and how communication with clients is done via web conferences.

After the lunch break, Anja Raack from the Graduate Recruitment team presented more about recruitment topics and gave useful advice on how to write professional emails.   After a short group assignment, where all participants had to identify common mistakes done in an email, a quiz completed this special day. All 5 groups showed a lot of enthusiasm during this game but no one had to worry as every single participant was rewarded with a prize and certificate.   To sum it up, we were very proud to host the girls for half a day and were impressed by their dedication. Hopefully, sooner or later, we will see some of them coming back to Oracle – either for the next Girl´s Day or one of our entry level positions. This day has shown that everyone can start a challenging career within an exciting industry. What matters is dedication and commitment to strive for the best.  Do you want to find out more about our job opportunities? Follow us on http://campus.oracle.com.

  • Framework 4 Features: User Propogation to the Database

    - by Anthony Shorten
    Once of the features I mentioned in a previous entry was the ability for Oracle Utilities Application Framework V4 to automatically propogate the end user to the database connection. This bears more explanation. In the past releases of the Oracle Utilities Application Framework, all database connections are pooled and shared within a channel of access. So for example, the online connections on the Business Application Server share a common pool of connections and the batch in a thread pool shares a seperate pool of connections. The connections are pooled for performance reasons (the most expensive part of a typical transaction is opening and closing connections so we save time by having them ready beforehand). The idea is that when a business function needs some SQL to be execute it takes a spare connection from the pool, executes the SQL and then returns the connection back to the pool for reuse. Unfortunelty to support the pool being started and ready before the transactions arrives means that you need to have a shared userid (as you dont know the users who need them beforehand). Therefore each connection uses the same database user to execute the SQL it needs. This is acceptable for executing transactions, generally but does not allow the DBA or other tools to ascertain which end user is actually running the transaction. In Oracle Utilities Application Framework V4, we now set the CLIENT_IDENTIFIER to the end userid (not the Login Id) when the connection is taken from the pool and used and reset it back to blank when returned to the pool. The CLIENT_IDENTIFIER is a feature that is present in the Oracle Database connection information. From a monitoring perspective, when a connection to the database is actively running SQL, the end user is now able to be determined by querying the CLIENT_IDENTIFIER on the session object within the database. This can be done in the DBA's favorite monitoring tool (even just some SQL on the v$session table is enough). This has other implications as well. Oracle sells a lot of other security addons to the database and so do third parties. If a site wants to have additional levels of security or auditing in the database then the CLIENT_IDENTIFIER, if supported, is now available to be recorded or used by those products to provide additional levels of security. This facility was one of the highly "nice to haves" that customers would ask us about so we now allow it to be used to allow finer grained monitoring and additional security facilities. Note: This facility is only available for customers using the Oracle Database versions of our products.

  • Interviews: Going Beyond the Technical Quiz

    - by Tony Davis
    All developers will be familiar with the basic format of a technical interview. After a bout of CV-trawling to gauge basic experience, strengths and weaknesses, the interview turns technical. The whiteboard takes center stage and the challenge is set to design a function or query, or solve what on the face of it might seem a disarmingly simple programming puzzle. Most developers will have experienced those few panic-stricken moments, when one’s mind goes as blank as the whiteboard, before un-popping the marker pen, and hopefully one’s mental functions, to work through the problem. It is a way to probe the candidate’s knowledge of basic programming structures and techniques and to challenge their critical thinking. However, these challenges or puzzles, often devised by some of the smartest brains in the development team, have a tendency to become unnecessarily ‘tricksy’. They often seem somewhat academic in nature. While the candidate straight out of IT school might breeze through the construction of a Markov chain, a candidate with bags of practical experience but less in the way of formal training could become nonplussed. Also, a whiteboard and a marker pen make up only a very small part of the toolkit that a programmer will use in everyday work. I remember vividly my first job interview, for a position as technical editor. It went well, but after the usual CV grilling and technical questions, I was only halfway there. Later, they sat me alongside a team of editors, in front of a computer loaded with MS Word and copy of SQL Server Query Analyzer, and my task was to edit a real chapter for a real SQL Server book that they planned to publish, including validating and testing all the code. It was a tough challenge but I came away with a sound knowledge of the sort of work I’d do, and its context. It makes perfect sense, yet my impression is that many organizations don’t do this. Indeed, it is only relatively recently that Red Gate started to move over to this model for developer interviews. Now, instead of, or perhaps in addition to, the whiteboard challenges, the candidate can expect to sit with their prospective team, in front of Visual Studio, loaded with all the useful tools in the developer’s kit (ReSharper and so on) and asked to, for example, analyze and improve a real piece of software. The same principles should apply when interviewing for a database positon. In addition to the usual questions challenging the candidate’s knowledge of such things as b-trees, object permissions, database recovery models, and so on, sit the candidate down with the other database developers or DBAs. Arm them with a copy of Management Studio, and a few other tools, then challenge them to discover the flaws in a stored procedure, and improve its performance. Or present them with a corrupt database and ask them to get the database back online, and discover the cause of the corruption.

  • Working with EO composition associations via ADF BC SDO web services

    - by Chris Muir
    ADF Business Components support the ability to publish the underlying Application Modules (AMs) and View Objects (VOs) as web services through Service Data Objects (SDOs).  This blog post looks at a minor challenge to overcome when using SDOs and Entity Objects (EOs) that use a composition association. Using the default ADF BC EO association behaviour ADF BC components allow you to work with VOs that are based on EOs that are a part of a parent-child composition association.  A composition association enforces that you cannot create records for the child outside the context of the parent.  As example when creating invoice-lines you want to enforce the individual lines have a relating parent invoice record, it just simply doesn't make sense to save invoice-lines without their parent invoice record. In the following screenshot using the ADF BC Tester it demonstrates the correct way to create a child Employees record as part of a composition association with Departments: And the following screenshot shows you the wrong way to create an Employee record: Note the error which is enforced by the composition association: (oracle.jbo.InvalidOwnerException) JBO-25030: Detail entity Employees with row key null cannot find or invalidate its owning entity.  Working with composition associations via the SDO web services  Shay Shmeltzer recently recorded a good video which demonstrates how to expose your ADF Business Components through the SDO interface. On exposing the VOs you get a choice of operation to publish including create, update, delete and more: For example through the SDO test interface we can see that the create operation will request the attributes for the VO exposed, in this case EmployeesView1: In this specific case though, just like the ADF BC Tester, an attempt to create this record will fail with JBO-25030, the composition association is still enforced: The correct way to to do this is through the create operation on the DepartmentsView1 which also lets you create employees record in context of the parent, thus satisfying the composition association rule: Yet at issue here is the create operation will always create both the parent Departments and Employees records.  What do we do if we've already previously created the parent Departments records, and we just want to create additional Employees records for that Department?  The create method of the EmployeeView1 as we saw previously doesn't allow us to do that, the JBO-3050 error will be raised. The solution is the "merge" operation on the parent Departments record: In this case for the Departments record you just need to supply the DepartmentId of the Department you want the Employees record to be associated with, as well as the new Employees record.  When invoked only the Employees record is created, and the supply of the DepartmentId of the Departments record satisfies the composition association without actually creating or updating the associated Department record that already exists in the database. Be warned however if you supply any more attributes for the Department record, it will result in a merge (update) of the associated Departments record too.

  • Third Party Applications and Other Acts of Violence Against Your SQL Server

    - by KKline
    I just got finished reading a great blog post from my buddy, Thomas LaRock ( t | b ), in which he describes a useful personal policy he used to track changes made to his SQL Servers when installing third-party products. Note that I'm talking about line-of-business applications here - your inventory management systems and help desk ticketing apps. I'm not talking about monitoring and tuning applications since they, by their very nature, need a different sort of access to your back-end server resources....(read more)

  • learning on the clock

    - by T. Webster
    Some might argue this question is too general, but because keeping up seems especially relevant to programming, is anyone's experience that: do employers expect you to stay current? what is the "industry standard" of expected time a programmer should spend keeping up-to-date? is it generally acceptable that a programmer can spend some time during working hrs on meeting the expectation to keep skills current? If not, how do most programmers find the time? -

  • Where does the "mm" come from in GTKmm, glibmm, etc

    - by Cole Johnson
    I understand that the "mm" suffix [in various GTK-associated C++ binding libraries] means "minus minus," but where exactly does it come from? I understand that there is a programming language called "C--," but if there were bindings (and I'm pretty sure I've seen some), they would be suffixed "--". TL;DR: Is there some page on gnu.org that explains the "mm" suffix in various C++ bindings or is it just a de facto standard adopted by the open source community with no reasoning behind it?

  • Pronunciation of "char"

    - by Zannjaminderson
    I know there's another question on here already about pronunciation here, but it's got a whole list of programming terms. I'm just interested in finding out how everybody pronounces just one thing - "char". I personally like "care" as in the first syllable of "character", since that's what it represents, but in past experience I've found there are far more people who say "char" as in "char-broiled", and some who say "car". Sorry to start a holy war, but I'm curious.
