• Javascript Canvas Drawing Efficiency

  - by jujumbura

  I have just recently started some experiments with game development in Javascript/HTML5, and so far it has been going pretty well. I have a simple test scene running with some basic input handling, and a hundred-ish drawImage() calls with a few transforms. This all runs great on Chrome, but unfortunately, it already chugs on Firefox. I am using a very large canvas ( 1920 x 1080 ), but it doesn't seem like I should be hitting my limit already. So on that note, I was hoping to ask a few questions: 1) What exactly is done on the CPU vs. the GPU in terms of canvas and drawImage()? I'm afraid the answer is probably "it depends on the browser", but can anybody give me some rules of thumb? I naively imagined that each drawImage call results in a textured quad on the GPU with the canvas effectively being a render target, but I'm wondering if I'm pretty far off base there... 2) I have seen posts here and there with people saying not to use the translate(), rotate(), scale() functions when drawing on the canvas. Am I adding a lot of overhead just by adding a translate() call, as opposed to passing in the x,y to drawImage()? Some people suggest using "transate3d", etc., which are CSS properties, but I'm not sure how to use them within a scene. Can they be used for animated sprites within a single canvas? 3) I have also seen a lot of posts with people mentioning that pre-building canvases and then re-using them is a lot faster than issuing all the individual draw calls again. I am guessing that my background should definitely be pre-built into a canvas, but how far should I take this? Should I maintain an individual canvas for each sprite, to cache all static image data when not animating? Thank you much for your advice!

• How to suppress or disable the shutdown option from indicator menu or shutdown dialog?

  - by user73093

  My goal is to allow user only to restart the system, and deny any shutdown (suspend, hibernate). I am running unity-2d. I 've managed to deny suspend and hibernate with polkit policy files like explained in How to disable shutdown/reboot/suspend/hibernate? I observed that is has somehow disable shutdown abilities, but hasn't removed "shutdown" entry from the indicator panel menu neither as well as the "shutdown..." button from the shutdown dialog. Pressing shutdown button at this point restarts lightdm, returning to the login screen. My goal is to remove any "shutdown" action and button. So, I 've added an ovveride file in /usr/share/glib-2.0/schemas that contains some rules: [com.canonical.indicator.session] suppress-shutdown-menuitem = true (all suppress-*-menuitem has "false" value by default in the schema) Compiling, restarting X, now there is an entry "close session..." in the indicator panel menu...: it's not what I want. at this point, if I set another entry suppress-logout-menuitem to true I got no entry in the indicator panel menu. Trying like this all combination doesn't give the opportunity to remove "shutdown" references/buttons without removing restart option. All I want is to remove any reference to "shutdown" but keep a "restart" option somewhere in the indicator menu... Thanks !

• How does font rendering actually work?

  - by Andrea

  I realize that I know essentially nothing about the way fonts get rendered in my computer. From what I can observe, font rendering is generally made in a consistent way throughout the system. For instance, the subpixel font hinting settings that I configure in my DE control panel have influence on text which appears on window borders, in my browser, in my text editor and so on. (I should observe that some Java applications show a noticeable difference, so I guess they are using a different font rendering mechanism). What I get from the above is that probably all applications that need font rendering make use of some OS (or DE)-wide library. On the other hand, browsers usually manage their own rendering through a rendering engine, that takes care of positioning various items - including text - according to specific flow rules. I am not sure how these two facts are compatible. I would assume that the browser would have to ask the OS to draw a glyph at a given position, but how can it manage the flow of text without knowing beforehand how much space the glyph will take? Are there separate calls to determine the glyph sizes, so that the browser can manage the flow as if characters were little boxes that are later filled in by the OS? (Although this does not take care of kerning). Or is the OS responsible for drawing a whole text area, including text flow? Does the OS return the rendered glyph as a bitmap and leaves it to the application to draw that on the screen?

• How to add precedence to LALR parser like in YACC?

  - by greenoldman

  Please note, I am asking about writing LALR parser, not writing rules for LALR parser. What I need is... ...to mimic YACC precedence definitions. I don't know how it is implemented, and below I describe what I've done and read so far. For now I have basic LALR parser written. Next step -- adding precedence, so 2+3*4 could be parsed as 2+(3*4). I've read about precedence parsers, however I don't see how to fit such model into LALR. I don't understand two points: how to compute when insert parenthesis generator how to compute how many parenthesis the generator should create I insert generators when the symbols is taken from input and put at the stack, right? So let's say I have something like this (| denotes boundary between stack and input): ID = 5 | + ..., at this point I add open, so it gives ID = < 5 | + ..., then I read more input ID = < 5 + | 5 ... and more ID = < 5 + 5 | ; ... and more ID = < 5 + 5 ; | ... At this point I should have several reduce moves in normal LALR, but the open parenthesis does not match so I continue reading more input. Which does not make sense. So this was when problem. And about count, let's say I have such data < 2 + < 3 * 4 >. As human I can see that the last generator should create 2 parenthesis, but how to compute this? After all there could be two scenarios: ( 2 + ( 3 *4 )) -- parenthesis is used to show the outcome of generator or (2 + (( 3 * 4 ) ^ 5) because there was more input Please note that in both cases before 3 was open generator, and after 4 there was close generator. However in both cases, after reading 4 I have to reduce, so I have to know what generator "creates".

• Smooth waypoint traversing

  - by TheBroodian

  There are a dozen ways I could word this question, but to keep my thoughts in line, I'm phrasing it in line with my problem at hand. So I'm creating a floating platform that I would like to be able to simply travel from one designated point to another, and then return back to the first, and just pass between the two in a straight line. However, just to make it a little more interesting, I want to add a few rules to the platform. I'm coding it to travel multiples of whole tile values of world data. So if the platform is not stationary, then it will travel at least one whole tile width or tile height. Within one tile length, I would like it to accelerate from a stop to a given max speed. Upon reaching one tile length's distance, I would like it to slow to a stop at given tile coordinate and then repeat the process in reverse. The first two parts aren't too difficult, essentially I'm having trouble with the third part. I would like the platform to stop exactly at a tile coordinate, but being as I'm working with acceleration, it would seem easy to simply begin applying acceleration in the opposite direction to a value storing the platform's current speed once it reaches one tile's length of distance (assuming that the tile is traveling more than one tile-length, but to keep things simple, let's just assume it is)- but then the question is what would the correct value be for acceleration to increment from to produce this effect? How would I find that value?

• Defining formula through user interface in user form

  - by BriskLabs Pakistan

  I am a student and developing a simple assignment - windows form application in visual studio 2010. The application is suppose to construct formulas as per user requirement. The process: It has to pick data from columns of Microsoft Access database and the user should be able to pick the data by column name like we do in a drop down menu. and create reusable formulas in it ( configure it once and can change it again). followings are column titles from database that can be picked for example. e.g Col -1 : Marks in Maths Col -2 : Total Marks in Maths Col -3 : Marks in science Col -4 : Total marks in science Finally we should be able to construct any formula in the UI like (Col 1 + Col 3 ) / ( col 2 + col 4) = Formula 1 once this is formula is set saved and a name is assigned to it by user. he/she can use the formula and results shall appear in a window below. i.e He would be able to calculate his desired figures (formula) by only manipulating underlying data on the UI layer....choose the data for a period and apply the formula and get the answer Problem: It looks like I have to create an app where rules are set through UI....... this means no stored procedures are required in SQL.... please suggest the right approach.

• Designing business objects, and gui actions

  - by fozz

  Developing a product ordering system using Java SE 6. The previous implementations used combo boxes, text fields, and check boxes. Preforming validation on action events from the GUI. The validation includes limiting existing combo boxes items, or even availability. The issue in the old system was that the action was received and all rules were applied to the entire business object. This resulted in a huge event change as options were changed multiple times. To be honest I have no idea how an infinite loop wasn't produced. Through the next iteration I stepped in and attempted to limit the chaos by controlling the order in which the selections could be made. Making configuration of BO's a top down approach. I implemented custom box models, action events, beans/binding, and an MVC pattern. However I still am unable to fully isolate action even chains. I'm thinking that I've approached the whole concept backwards in an attempt to stay closest to what was already in place. So the question becomes what do I design instead? I'm currently considering an implementation of Interfaces, Beans, Property Change Listeners to manage the back and forth. Other thoughts were validation exceptions, dynamic proxies.... I'm sure there are a ton of different ways. To say that one way is right is crazy, and I'm sure it will take a blending of multiple patterns. My knowledge of swing/awt validation is limited, previously I did backend logic only. Other considerations are were some sort of binding(jgoodies or otherwise) to directly bind GUI state to BO's.

• How successful is GPL in reaching its goals?

  - by StasM

  There are, broadly, two types of FOSS licenses when it relates to commercial usage of the code - let's say the GPL-type and the BSD-type. The first is, broadly, restrictive about commercial usage (by usage I also mean modification and redistribution, as well as creating derived works, etc.) of the code under the license, and the second is much more permissive. As I understand, the idea behind GPL-type licenses is to encourage people to abandon the proprietary software model and instead convert to the FOSS code, and the license is the instrument to entice them to do so - i.e. "you can use this nice software, but only if you agree to come to our camp and play by our rules". What I want to ask is - was this strategy successful so far? I.e. are there any major achievements in the form of some big project going from closed to open because of GPL or some software being developed in the open only because GPL made it so? How big is the impact of this strategy - compared, say, to the world where everybody would have BSD-type licenses or release all open-source code under public domain? Note that I am not asking if FOSS model is successful - this is beyond question. What I am asking is if the specific way of enticing people to convert from proprietary to FOSS used by GPL-type and not used by BSD-type licenses was successful. I also don't ask about the merits of GPL itself as the license - just about the fact of its effectiveness.

• Hello PCI Council, are you listening?

  - by David Dorf

  Mention "PCI" to any retailer and you'll instantly see them take a deep breath and start looking for the nearest exit.  Nobody wants to be insecure, but few actually believe that PCI does anything more than focus blame directly on retailers.  I applaud PCI for making retailers more aware of the importance of security, but did you have to make them PAINFULLY aware?  POS vendors aren't immune to this pain either as we have to undergo lengthy third-party audits in addition to the internal secure programming programs.  There's got to be a better way. There's a timely article over at StorefrontBacktalk that discusses the inequity of PCI's rules, and also mentions that the PCI Council is accepting comments until April 15th. As a vendor, my biggest issue with PCI is that they require vendors to disclose the details of any breaches, in effect "ratting out" customers.  I don't think its a vendor's place to do this.  I'd rather have the trust of my customers so we can jointly solve the problem. Mary Ann Davidson, Oracle's Chief Security Officer, has an interesting blog posting on this very topic.  Its a bit of a long read, but I found it very entertaining and thought-provoking.  Here's an excerpt: ...heading up the list of “you must be joking” regulations are recent disturbing developments in the Payment Card Industry (PCI) world. I’d like to give [the] PCI kahunas the benefit of the doubt about their intentions, except that efforts by Oracle among others to make them aware of “unfortunate side effects of your requirements” – which is as tactful I can be for reasons that I believe will become obvious below - have gone, to-date, unanswered and more importantly, unchanged. I encourage you to read the entire posting, Pain Comes Instantly, and then provide feedback to the PCI Council.

• How do you make people accept code review?

  - by user7197

  All programmers have their style of programming. But some of the styles are let’s say... let’s not say. So you have code review to try to impose certain rules for good design and good programming techniques. But most of the programmers don’t like code review. They don’t like other people criticizing their work. Who do they think they are to consider themselves better than me and tell me that this is bad design, this could be done in another way. It works right? What is the problem? This is something they might say (or think but not say which is just as bad if not worse). So how do you make people accept code review without starting a war? How can you convince them this is a good thing; that will only improve their programming skills and avoid a lot of work later to fix and patch a zillion times a thing that hey... "it works"? People will tell you how to make code review (peer-programming, formal inspections etc) what to look for in a code review, studies have been made to show the number of defects that can be discovered before the software hits production etc. But how do you convince programmers to accept a code review?

• TransformXml Task locks config file identified in Source attribute

  - by alexhildyard

  As background: the TransformXml MSBuild task is typically invoked in a custom build step to mark up a web.config file with per-environment configuration; its flexible directives offer highly granular control over the insertion, removal, substitution and transformation of existing configuration hierarchies. For those using the TransformXML task (typically in a Web Deployment Project) I raised an issue against Visual Studio 2010, in which the file handle on the input file was not released, meaning that following transformation the source file remained locked. As a result, the best way to transform a file was first to rename it, transform it, and then copy it back, leaving the "locked" file to be freed up later.I just heard today that this has now been resolved in Visual Studio 2012 RTM. That's good news, because Web Config Transformations offer a lot. An intelligent, automated build process will swap in the relevant transform(s), making it much easier to synthesise the Developer and Build server builds. This makes for a simpler and more exemplary build process, and with the tighter coupling comes a correspondingly quicker response to Developmental change.Oh, and don't forget -- it isn't just web.configs you can transform. You can transform app.configs, or indeed any XML file that honours the task's schema and hierarchical rules.

• Am I an idealist?

  - by ereOn

  This is not only a question, this is also a call for help. Since I started my career as a programmer, I always tried to learn from my mistakes. I worked hard to learn best-practices and while I don't consider myself a C++ expert, I still believe I'm not a beginner either. I was recently hired into a company for C++ development. There I was told that my way to work was "against the rules" and that I would have to change my mind. Here are the topics I disagree with my hierarchy (their words): "You should not use separate header files for your different classes. One big header file is both easier to read and faster to compile." "Trying to use different headers is counter-productive : use the same super-set of headers everywhere, and enforce the use #pragma hdrstop to hasten compilation" "You may not use Boost or any other library that uses nested directories to organize its files. Our build-machine doesn't work with nested directories. Moreover, you don't need Boost to create great software." One might think I'm somehow exaggerated things, but the sad truth is that I didn't. That's their actual words. I believe that having separate files enhance maintainability and code-correctness and can fasten compilation time by the use of the proper includes. Have you been in a similar situation? What should I do? I feel like it's actually impossible for me to work that way and day after day, my frustration grows.

• How to get started in the development industry? [closed]

  - by Peter Fren

  My life is coding. I was born in 1982 and my first computer was an amiga. I started learning Amiga BASIC. To cut a long story short, I know many things about several programming languages. Being unemployed(I achieved the german abitur, should be similar to a high school degree and I studied a few semesters of mechanical engineering in 2002(I learned JAVA back then)) I have no idea how to use this ability. I have never done commissional work, every task I solved was based on my own wishes and desires. I do not know how to write a FSD or PRD or put it into code. So the question is, why should anyone hire me? I specialized in kinect development but all jobs I applied for on odesk and similar were awarded to others without me knowing why. I don't know what I should do with my skills professionally. What do you suggest? As this board has weird rules, tell me where to find answers if this is the wrong place.

• Are long methods always bad?

  - by wobbily_col

  So looking around earlier I noticed some comments about long methods being bad practice. I am not sure I always agree that long methods are bad (and would like opinions from others). For example I have some Django views that do a bit of processing of the objects before sending them to the view, a long method being 350 lines of code. I have my code written so that it deals with the paramaters - sorting / filtering the queryset, then bit by bit does some processing on the objects my query has returned. So the processing is mainly conditional aggregation, that has complex enough rules it can't easily be done in the database, so I have some variables declared outside the main loop then get altered during the loop. varaible_1 = 0 variable_2 = 0 for object in queryset : if object.condition_condition_a and variable_2 > 0 : variable 1+= 1 ..... ... . more conditions to alter the variables return queryset, and context So according to the theory I should factor out all the code into smaller methods, so That I have the view method as being maximum one page long. However having worked on various code bases in the past, I sometimes find it makes the code less readable, when you need to constantly jump from one method to the next figuring out all the parts of it, while keeping the outermost method in your head. I find that having a long method that is well formatted, you can see the logic more easily, as it isn't getting hidden away in inner methods. I could factor out the code into smaller methods, but often there is is an inner loop being used for two or three things, so it would result in more complex code, or methods that don't do one thing but two or three (alternatively I could repeat inner loops for each task, but then there will be a performance hit). So is there a case that long methods are not always bad? Is there always a case for writing methods, when they will only be used in one place?

• Part 4: Development Standards or How to share

  - by volker.eckardt(at)oracle.com

  Although we usually introduce the custom development part in EBS projects as “a small piece only” and “we will avoid as best as possible”, the development effort can be enormous and should therefore be well addressed by project standards. Any additional solution or additional software tool or product shall influence the custom development rules (by adding, removing or replacing sections). It is very common in EBS projects to create a so called “MD.030 Development Standards” document and put everything what’s related to development conventions into it. This document gets approval and will be shared among all developers. Later, additional sections have to be added, and usually the development lead is responsible for doing this. However, sometimes used development techniques are not documented properly, and therefore the development solutions deviate from each other, or from the initially agreed standards. My advice would be the following: keep the MD.030 as a base document, and add a Wiki on top. The “Development Wiki” covers the following: Collect input from every developer without updating the MD.030 directly Collect additional topics that might need further specification Allow a discussion about such topics by reviewing/updating the wiki directly Add also decisions or open questions right into it. In one of my own projects we were using this “Developer Wiki” quite extensive, and my experience is very positive. We had different sections in it, good cross references, but also additional material like code templates, links to external web pages etc. By using this wiki, the development standards became “owned” by the right group of people, the developers. They recognized that information sharing can improve the overall development quality, but will also reduce the workload on individuals. Finally, the wiki was much more accurate and helpful for the daily development work than our initial MD.030, and we all decided to retire the document completely. Summary: Information sharing in the development area is very important! The usual “MD.030 Development Standards“ is a good starting point, but should be combined with a “Development Wiki”, allowing everyone to address and discuss necessary improvements. A well-structured Wiki can replace the document in some sections completely. Side Note: The corresponding task in Oracle OUM (Oracle Unified Method) is DS.050 ‘Determine Design and Build Standards’ Volker

• Enforcing Constraints Upon Data Documents of Various Formats

  - by Christopher Berman

  This seems like the sort of problem that must have been solved elegantly long ago, but I haven't the foggiest how to google it and find it. Suppose you're maintaining a large legacy system, which has a large collection of data (tens of GB) of various formats, including XML and two different internal configuration formats. Suppose further that there are abstract rules governing the values these files may or may not contain. EXAMPLE: File A defines the raw, mathematical data pertaining to the aerodynamics of a car for consumption of the physics component of the system. File B contains certain values from File A in an easily accessible, XML hierarchy for consumption of a different component of the system. There exists, therefore, an abstract rule (or constraint) such that the values from File B must match the values from File A. This is probably the simplest constraint that can be specified, but in practice, the constraints between files can become very complicated indeed. What is the best method for managing these constraints between files of arbitrary formats, short of migrating it over to an RDBMS (which simply isn't feasible for the foreseeable future)? Has this problem been solved already? To be more specific, I would expect the solution to at least produce notifications of violated constraints; the solution need not resolve the constraints. ============================== Sample file structures File A (JeepWrangler2011.emv): MODEL JeepWrangler2011 { EsotericMathValueX 11.1 EsotericMathValueY 22.2 EsotericMathValueZ 33.3 } File B (JeepWrangler2011.xml): <model name="JeepWrangler2011"> <!--These values must correspond File A's EsotericMathValues--> <modelExtent x="11.1" y="22.2" z="33.3"/> [...] </model>

• Microsoft Changes Developer Account Registration Requirements

  - by Tim Murphy

  Over the last couple of weeks I have noticed that Microsoft seems to have changed the requirements for Corporate accounts.  These requirements were not in effect when I originally setup the account for the company that I work for.  We also recently had our corporate account canceled without explanation and are in the process of working to get it reinstated.  This all seems to revolve around rules to increase confidence that in the producers of content.  They are now having Symantec validate a company based on legal documents. In the past there have been problems with getting credit cards accepted.  We have had to setup new Live IDs to satisfy whatever glitch the system had or unexplainable requirement.  I am hoping that in the time that has elapsed these problems have been resolved. In truth I can’t say that these new requirements weren’t always in place, but it is getting frustrating to help clients setup accounts.  I am encourage that they have taken steps to safeguard the consumer from Joe-fly-by-night, but they also need to make sure that the process doesn’t become so complex that it drives away companies from participating in the store.  We will have to keep an eye on this as things evolve. del.icio.us Tags: Windows Phone Development,Windows 8 Development,Windows Phone,Windows 8,Registration,Corporate Accounts

• Implementing new required feature after software release

  - by TiagoBrenck

  Fake Scenario There is a software that was released 1 year ago. The software is to map and register all kind of animals on our planet. When the software was released, the client only needed to know the scientific name of the animal, a flag if it is in risk of extinction and a scale of dangerous(that is a fake software and specification, I don't want to discuss this here). There are already 100.000 animals records saved on DB. New Feature One year later, the client wants a new feature. It is really important to him to know the animals classes, and this is a required field. So he asks me to put a field to input the animal class, and this field is required. Or maybe where this animal was discovered. Problem I have already 100.000 recorded animals without a class or where it was discovered, but I need to insert a new column to storage this information and this column can't be null. I don't have a default value for this situation (there isn't a default animal class or where it was discovered). I don't want to keep the requirement rule only on my software, my DB must have this requirement too(I like to keep business rules on DB too). What are the alternatives to solve this situation? I am on a situation that this new feature cannot be previewed or reviewed for the existing records. The time already passed and I can't go back on time to get it

• Caching by in-memory dictionaries. Are we doing it all wrong?

  - by user73983

  This approach is pretty much the accepted way to do anything in our company. A simple example : when a piece of data for a customer is requested from a service, we fetch all the data for that customer(relevant part to the service) and save it in a in-memory dictionary then serve it from there on following requests(we run singleton services). Any update goes to DB, then updates the in memory dictionary. It seems all simple and harmless but as we implement more complicated business rules the cache gets out of sync and we have to deal with hard to find bugs. Sometimes we defer writing to database, keeping new data in cache till then. There are cases when we store millions of rows in memory because the table has many relations to other tables and we need to show aggregate data quickly. All this cache handling is a big part of our codebase and I sense this is not the right way to do it. All of this juggling adds too much noise to the code and it makes it hard to understand the actual business logic. However I don't think we can serve data in a reasonable amount of time if we have to hit the database every time. I am unhappy about the current situation but I don't have a better alternative. My only solution would be to use NHibernate 2nd level cache but I have nearly no experience with it. I know many campanies use Redis or MemCached heavily to gain performance but I have no idea how I would integrate them into our system. I also don't know if they can perform better than in-memory data structures and queries. Are there any alternative approaches that I should look into?

• Web Crawler for Learnign Topics on Wikipedia

  - by Chris Okyen

  When I want to learn a vast topic on wikipedia, I don't know where to start. For instance say I want to learn about Binary Stars, I then have to know other things linked on that pages and linked pages on all the linked pages and so on for the specified number of levels. I want to write a web crawler like HTTracker or something similiar, that will display a heiarchy of the links on a certain page and the links on those linked pages.I wish to use as much prewritten code as possible. Here is an example: Pretending we are bending the rules by grabing links from only the first sentence of each pages The example archives and "processes" two levels deep The page is Ternary operation The First Level In mathematics a ternary operation is an N-ary operation The Second Level Under Mathmatics: Mathematics (from Greek µ???µa máthema, “knowledge, study, learning”) is the abstract study of topics encompassing quantity, structure, space, change and others; it has no generally accepted definition. Under N-ary In logic,mathematics, and computer science, the arity i/'ær?ti/ of a function or operation is the number of arguments or operands that the function takes Under Operation In its simplest meaning in mathematics and logic, an operation is an action or procedure which produces a new value from one or more input values ------------------------------------------------------------------------- I need some way to determine what oder to approach all these wiki pages to learn the concept ( in this case ternary operations )... Following along with this exmpakle, one way to show the path to read would a printout flowout like so: This shows that the first sentence of the Mathematics page doesn't link to the first sentence of pages linked on ternary page two levels deep. (Please tell me how I should explain this ) --- In otherwords, the child node of the top pages first sentence, ternary_operation, does not have any child nodes that reference the children of the top pages other children nodes- N-ary and operation. Thus it is safe to read this first. Since N-ary has a link to operations we shoudl read the operation page second and finally read the N-ary page last. Again, I wish to use as much prewritten code as possible, and was wondering what language to use and what would be the simpliest way to go about doing this if there isn't already somethign out there? Thank You!

• How to Structure a Trinary state in DB and Application

  - by ABMagil

  How should I structure, in the DB especially, but also in the application, a trinary state? For instance, I have user feedback records which need to be reviewed before they are presented to the general public. This means a feedback reviewer must see the unreviewed feedback, then approve or reject them. I can think of a couple ways to represent this: Two boolean flags: Seen/Unseen and Approved/Rejected. This is the simplest and probably the smallest database solution (presumably boolean fields are simple bits). The downside is that there are really only three states I care about (unseen/approved/rejected) and this creates four states, including one I don't care about (a record which is seen but not approved or rejected is essentially unseen). String column in the DB with constants/enum in application. Using Rating::APPROVED_STATE within the application and letting it equal whatever it wants in the DB. This is a larger column in the db and I'm concerned about doing string comparisons whenever I need these records. Perhaps mitigatable with an index? Single boolean column, but allow nulls. A true is approved, a false is rejected. A null is unseen. Not sure the pros/cons of this solution. What are the rules I should use to guide my choice? I'm already thinking in terms of DB size and the cost of finding records based on state, as well as the readability of code the ends up using this structure.
