• Am I making the right decision to take Information technology/system as my course in college?

  - by 123rainfan

  I am a student who just ended my high school last year. I will be entering college any time between march to August. And.. I am thinking of studying Information technology/System as my course in college. The problem is, I am unsure if this is the right path for me. I don't know if this is what I really want for my future later on! Yes, I do love learning more about computers (prefer software to hardware). But what if I don't find them interesting later on when studying? I'm worried about that as I don't wanna regret later on. To add to that, my knowledge of programming and other software development is actually quite low. Can someone advise me on what should I do? Or tell me more about Information technology (what will I study later on in college and the career path)?

• Web Apps: Closeable Announcements/Info/Tooltip boxes (how to implement)

  - by Daxon

  I want to understand how to implement an announcement/info box system that displays a box for the user with information. The user can do nothing or close the box, but then it will never be seen again. E.g. Facebook home page. Box asking for Translators. if you leave it then its always there. But if you close it, it never appears again. Does this mean that a Boolean value needs to be used and checked for announcement/info boxes? I'm looking for a pseudo way with database tables to do this?

• Is Software Development a Part of IT

  - by kzh

  I am not sure if this question is in the scope of SO, but I will ask anyway... I am currently going to school, majoring in Computer Science. Often I overhear students in the Management of Information Systems major call themselves programmers. These comments make me angry for a few reasons: They seem to trivialize what I do. Most of them are not even capable of doing what I can do. To me, MIS is IT and the are technicians and software developers are engineers and are not IT. So I guess my question is, Is software development part of IT? I often see them lumped together.

• The best way to display data in a table view?

  - by LawVS

  Hey guys, I'm trying to display nutritional information in a table view but am struggling about the best way to show the info. I don't want to create unique views for each page as that would take up a lot of space. My ideal avenue would be like a website having links to data pages instead of individual views for each page. How would I best implement that? For example, I would want the first page to be a list of restaurants, then as you press the restaurant it would list the different types of food...the next page would be a list of those foods and then the final page would be the nutrition info itself. Thanks

• Incorrect value for UNIQUE_CONSTRAINT_NAME in REFERENTIAL_CONSTRAINTS

  - by van

  I am listing all FK constraints for a given table using INFORMATION_SCHEMA set of views with the following query: SELECT X.UNIQUE_CONSTRAINT_NAME, "C".*, "X".* FROM "INFORMATION_SCHEMA"."KEY_COLUMN_USAGE" AS "C" INNER JOIN "INFORMATION_SCHEMA"."REFERENTIAL_CONSTRAINTS" AS "X" ON "C"."CONSTRAINT_NAME" = "X"."CONSTRAINT_NAME" AND "C"."TABLE_NAME" = 'MY_TABLE' AND "C"."TABLE_SCHEMA" = 'MY_SCHEMA' Everything works perfectly well, but for one particular constraint the value of UNIQUE_CONSTRAINT_NAME column is wrong, and I need it in order to find additional information from the referenced Column. Basically, for most of the rows the UNIQUE_CONSTRAINT_NAME contains the name of the unique constraint (or PK) in the referenced table, but for one particular FK it is the name of some other unique constraint. I dropped and re-created the FK - did not help. My assumption is that the meta-data is somehow screwed. Is there a way to rebuild the meta data so that the INFORMATION_SCHEMA views would actually show the correct data?

• Can we 301 redirect to a new page, but still publish the old content somewhere else?

  - by KBS

  We have a page on the site which ranks well for an SEO term (top 5) but contains old information. We have added a new page but Google doesn't rank it that well. Information on these pages is time sensitive. Old: example.com/2013-related-information.html New: example.com/2014-related-information.html Obvious solution is to delete old page and do a 301 redirect to the new page. Now, can we still keep the old page by giving it a new URL. example.com/2013-related-information.html is redirected to example.com/2014-related-information.html example.com/2014-related-information.html is recreated with a new address such as example.com/new-2013-related-information.html What we are trying to do is to send the user to the fresh page but still not destroying the record copy if someone wants to go and dig up the old information.

• Assistance with building an inverted-index

  - by tipu

  It's part of an information retrieval thing I'm doing for school. The plan is to create a hashmap of words using the the first two letters of the word as a key and any words with the two letters saved as a string value. So, hashmap["ba"] = "bad barley base" Once I'm done tokenizing a line I take that hashmap, serialize it, and append it to the text file named after the key. The idea is that if I take my data and spread it over hundreds of files I'll lessen the time it takes to fulfill a search by lessening the density of each file. The problem I am running into is when I'm making 100+ files in each run it happens to choke on creating a few files for whatever reason and so those entries are empty. Is there any way to make this more efficient? Is it worth continuing this, or should I abandon it? I'd like to mention I'm using PHP. The two languages I know relatively intimately are PHP and Java. I chose PHP because the front end will be very simple to do and I will be able to add features like autocompletion/suggested search without a problem. I also see no benefit in using Java. Any help is appreciated, thanks.

• For the .com TLD, is there any known change tracking for WhoIs information?

  - by makerofthings7

  A client exposed information regarding what will become a controversial website in the domain WhoIs after she purchased it from auction. Is there any whois cache that will detect, save, and share the old whois information for that domain, after it has changed? (It's a website to provide birth control in countries where it is banned, and she may receive death threats for the information shared on it. Obviously something she wishes to avoid.)

• Who is likely to need the most this high-quality, measurable, reliable approach to software? [closed]

  - by Marek Cruz

  Software engineering is the application of principles of engineering to software. Trouble is, most of those who like to flatter with the title "software engineer" don't do that. They just keep writing code and patching it until it's stable enough to foist off on users. That's not software engineering. Who is likely to need the most the practice of software engineering? (with all the project planning, requirements engineering, software design, implementation based on the design, testing, deployment, awareness of IEEE standards, metrics, security, dependability, usability, etc.)

• Does one's native spoken language affect quality of code?

  - by Xepoch

  There is a school of thought in linguistics that problem solving is very much tied to the syntax, semantics, grammar, and flexibility of one's own native spoken language. Working with various international development teams, I can clearly see a mental culture (if you will) in the codebase. Programming language aside, the German coding is quite different from my colleagues in India. As well, code is distinctly different in Middle America as it is in Coastal America (actually, IBM noticed this years ago). Do you notice with your international colleagues (from ANY country) that coding style and problem solving are in-line with native tongues?

• What are some high quality Enterprise Architecture conferences or training programs?

  - by Stimy

  I am looking for a conference or training which will give me a broad exposure to enterprise level software architecture. I've been with the same company for 10 years and we've grown to the size where we really need to lay out a framework for the applications which support our company's business. The organic growth over the last 10 years has left us with a tightly coupled and fairly messy set of applications. We need to do a better job at componentizing our business entities and have more rigorous control on the interfaces between those entities and our business processes. I'm looking to get a broad, yet practical exposure on design patterns to support that architecture (SOA, messaging, ESB's etc). I'm hoping to gain insight from folks who have direct experience with implementing or working with what would be considered an enterprise class architecture.

• Is there a Railstutorial-quality tutorial for a PHP framework?

  - by tnorthcutt

  Is there a tutorial along the lines of Michael Hartl's Rails Tutorial for a (widely used) PHP framework? Obviously there are tons of tutorials for e.g. Codeigniter, CakePHP, Symfony, etc., but I haven't been able to find one that is as extensive as Rails Tutorial is. Ideally, I'd like something that takes you from nothing to building a complete, functioning application with at least a decent amount of complexity.

• How do I find information on who links to my sites?

  - by bobdobbs

  I'm trying to figure out if there's a free way to get information on backlinks to my site. I've had webmaster tools and google analytics set up for years. But I can't find access to data about site backlinks in either toolset. Webmaster tools, under 'traffic'-'links to your site' gives me the same message for all of my sites: "No data available". I haven't been able to find anything in GA that gives any information on backlinks. I've heard of using "links:" as an operator in google search, but for each of my sites, this returns either zero or very few results in cases when I know I have many backlinks. Most of the links simple aren't shown. My thinking is that google maintains a graph of who links to my site, so I figured that they might let me see it. But I can't figure out how. I've found this tool on a spammy website: http://www.backlinkwatch.com. It offers more data than google on my backlines, and offers more results in exchange for a paid subscription. The data it offers for free looks good, but the results are limited and the site has popups and obnoxious ads. So, in short: how do I get data on who links to me? Is there a free way?

• My architecture has a problem with views that required information from different objects. How can I solve this?

  - by Oscar

  I am building an architecture like this: These are my SW layers ______________ | | | Views | |______________| ______________ | | |Business Logic| |______________| ______________ | | | Repository | |______________| My views are going to generate my HTML to be sent to the user Business logic is where all the business logics are Repository is a layer to access the DB My idea is that the repository uses entities (that are basically the representation of the tables, in order to perform DB queries. The layers communicate between themselves using Business Objects, that are objects that represent the real-world-object itself. They can contain business rules and methods. The views build/use DTOs, they are basically objects that have the information required to be shown on the screen. They expect also this kind of object on actions and, before calling the business logic, they create BO. First question: what is your overall feeling about this architecture? I've used similar architecture for some projects and I always got this problem: If my view has this list to show : Student1, age, course, Date Enrolled, Already paid? It has information from different BO. How do you think one should build the structure? These were the alternatives I could think of: The view layer could call the methods to get the student, then the course it studies, then the payment information. This would cause a lot of DB accesses and my view would have the knowledge about how to act to generate this information. This just seems wrong for me. I could have an "adapter object", that has the required information (a class that would have a properties Student, Course and Payment). But I would required one adapter object for each similar case, this may get very bad for big projects. I still don't like them. Would you have ideas? How would you change the architecture to avoid this kind of problems? @Rory: I read the CQRS and I don't think this suits my needs. As taken from a link references in your link Before describing the details of CQRS we need to understand the two main driving forces behind it: collaboration and staleness That means: many different actors using the same object (collaboration) and once data has been shown to a user, that same data may have been changed by another actor – it is stale (staleness). My problem is that I want to show to the user information from different BO, so I would need to receive them from the service layer. How can my service layer assemble and deliver this information? Edit to @AndrewM: Yes, you understood it correctly, the original idea was to have the view layer to build the BOs, but you have a very nice point about the creation of the BO inside the business layers. Assuming I follow your advice and move the creation logic inside the business layer, my business layer interface would contain the DTOs, for instance public void foo(MyDTO object) But as far as I understand, the DTO is tightly coupled to each view, so it would not be reusable by a second view. In order to use it, the second view would need to build a specific DTO from a specific view or I would have to duplicate the code in the business layer. Is this correct or am I missing something?

• Does a person's day-to-day neatness (outside of programming) relate to quality and organization in programming?

  - by jiceo

  Before anyone jumps into any conclusion, I had a discussion with a friend (who's not a programmer at all) about the relationship between a person's neatness habit and the degree of neatness generally shown in works by the same person. This led me to think about this situation: Let's imagine you knew a programmer whose house was very messy. This person's lifestyle is messy by nature. On his desk there are books, papers, STUFF, piled everywhere including on the floor, mixed with dirty clothing, with no obvious organization at all. If you asked him to find a book he hasn't touched for at least a week from the cluster of chaos, he would take at least an hour to do so. How likely is it that he will produce very clean, consistent, and organized code that other people can use? Are there CS legends that are/were notoriously messy in day-to-day habits?

• Where to find current information on quality of released games as software products?

  - by Tom

  As a gamer, one thing I have learned I need to be savvy about is knowing whether SomeBigGame is actually unstable or otherwise problematic as a piece of software (riddled with invasive DRM products, only runs well on a particular video driver version, crashes on non-English-language systems, etc.). I know that game news media can sometimes be relied upon to report on some problems, but I doubt they bother to cover smaller or indie titles. An example: I've started playing Transformice on Kongregate, and I'm considering installing the downloadable client (it is an online multiplayer game). The part of me that cares about data privacy and maintaining a clean-and-healthy PC wants to know whether there is a place I can check to find out more about a title-as-software than "it is not a literal virus." Put another way: where would you not want to see your game receive lots of attention?

• How to learn to deliver quality software designs when working on a tight deadline?

  - by chester89

  I read many books about how to design great software, but I kind of struggle to come up with a good design decisions when it comes to business apps, especially when the timeframe is tough. In the company I currently work for, the following situation happen all the time: my teamlead tells me that there's a task to do, I call some guy or a girl from business who tells me exactly what is it they want, and then I start coding. The task always fits in some existing application (we do only web apps or web services), usually it's purpose is to pull data from one datasource and put into the other one, with some business logic attached in the process. I start coding and then, after spending some time on a problem, my code didn't work as expected - either because of technical mistake or my lack of knowledge of the domain. The business is ringing me 2-3 times a day to hurry me up. I ask my team lead to help, he comes up, sees my code and goes like 'What's this?'. Then he throws away about half of my code, including all the design decisions I made, writes 2-3 methods that does the job (each of them usually 200-300 lines long or more, by the way), and task is complete, code works as it should have. The guy is smarter than me, obviously, and I'm aware of that. My goal is to be better software developer, that means write better code, not finish the job quicker with some crappy code. And the thing is, when I have enough time to tackle a problem, I can come up with a design that is good (in my opinion, of course), but I fall short to do so when I'm on a tight deadline. What should I do? I am fully aware that it's rather vague explanation, but please bear with me

• Don't Just Go For Cheap Offers From an SEO Company - Why Choose Quality Over Price?

  Let's face it; anything that requires you to dish out more money for the productivity of your business isn't conducive to one's ideals. Which means, the more money you dish out, the less your profit or revenues will be. This is one reason why many online businesses tend to opt for cheap offers from an SEO Company to curtail their expenses to maximize their profit -- or so they thought.
