• Future proof Primary Key design in postgresql

  - by John P

  I've always used either auto_generated or Sequences in the past for my primary keys. With the current system I'm working on there is the possibility of having to eventually partition the data which has never been a requirement in the past. Knowing that I may need to partition the data in the future, is there any advantage of using UUIDs for PKs instead of the database's built-in sequences? If so, is there a design pattern that can safely generate relatively short keys (say 6 characters instead of the usual long one e6709870-5cbc-11df-a08a-0800200c9a66)? 36^6 keys per-table is more than sufficient for any table I could imagine. I will be using the keys in URLs so conciseness is important.

• DataBinding and ErrorProvider - How to provide custom error messages?

  - by BeowulfOF

  We use BusinessObjects, implementing IDataErrorInfo and IEditableObject. BindingLists with those Objects are added to BindingSources, those are used to bind UserControls and DataGrids on the forms (WinForms). The BindingSource is additionally set as DataSource to the ErrorProvider of the form. We do use currently TextBoxes for Properties of Type int and short. They are validated inside the BusinessObjects with custom validation, like min/max values, etc. That works fine, since error message form our custom validations show up nicely next to the TextBox. However, if the input is greater than the value of an int (e.g. "9999999999") the BindingSource doesn't even try to enter that Value into the BusinesObject but instead gives the errormessage to the errorprovider like "The value for Int32 was too big.". We do not want to bother our users with "Int32" but want a custom errormessage for that. It is nice, that the BindingSource does provide this feature, but is it possible to provide custom error messages for this?

• Getting "on the wire" Size of Messages in WCF

  - by Mystagogue

  While I'm making SOAP or REST invocations to WCF, I'd like to have the channel stack on either end (client and server) record the on-the-wire size of the data received. So I'm guessing I need to add a custom behavior to the channel stack on either side. That is, on the server side I'd record the IP-header advertised size that was received. On the client side I'd record the IP-header advertised size that was returned from the server. But this presupposes that this information is visible to a custom WCF behavior at the channel stack level. Perhaps it is only visible at the level of ASP.NET (at a layer beneath WCF)? In short, does anyone have any further insight on if and how this information is accessible? I must qualify that this "size" data will be collected in a production environment, as part of regular business logic calls. This question is related to my earlier bandwidth question.

• How can I initialize a QTMovie object with certain attributes using writable data?

  - by c-had

  I'm trying to create an empty QTMovie object that I can add segments to, and then play. This is easy to do with something like: movie = [[QTMovie alloc] initToWritableData:[NSMutableData dataWithCapacity:1048576] error:&error]; I can then use -insertSegmentOfMovie to insert segments from other movies into this one so I can play it back. The problem is that I also need to set a certain attribute when creating the QTMovie object. In particular, I need to set the QTMovieRateChangesPreservePitchAttribute attribute, so that I can alter playback speed during playback without changing pitch. This attribute cannot be written after the movie is initialized. So, I can create the QTMovie object like this: movie = [[QTMovie alloc] initWithAttributes:[NSDictionary dictionaryWithObjectsAndKeys:[NSNumber numberWithBool:YES], QTMovieRateChangesPreservePitchAttribute, nil] error:&error]; Unfortunately, this is not editable. I've tried setting the QTMovieEditableAttribute as well on creation, but it does not help. I still get an exception when I try to insert anything into this movie. I presume this is because there is no writable file or data reference associated with the QTMovie. Any ideas on how to solve this?

• Problem with jQuery's fade in/out in Firefox

  - by GaVrA

  I already asked here with no luck, but feel free to read it: http://groups.google.com/group/jquery-en/browse%5Fthread/thread/fdf7a584b30d4bb9 Hmm check out my site: http://www.crtaci.info/ on top-right position i have search field. When you move your mouse over there small text shows up that says: Napredna pretraga Now, for some reason those letters change color to like yellow for very short period of time in ff 3.5 and to some strange color in safari 4.0.2 for win. In ie8, opera and chrome it works just the way it should, white letters stay white during the animation. Any sugestions? here is function that do this job ;) $('#header_search').hover(function() { $('#naprednaPretraga').stop({clearQueue:true}).show().animate({"opacity" : 1},500); }, function(){ $('#naprednaPretraga').stop({clearQueue:true}).animate({"opacity" : 0},500,function() { $('#naprednaPretraga').hide(); }); });

• Using a check contraint in MySQL for controlling string length

  - by ptrn

  I'm tumbled with a problem! I've set up my first check constraint using MySQL, but unfortunately I'm having a problem. When inserting a row that should fail the test, the row is inserted anyway. The structure: CREATE TABLE user ( id INT UNSIGNED NOT NULL AUTO_INCREMENT, uname VARCHAR(10) NOT NULL, fname VARCHAR(50) NOT NULL, lname VARCHAR(50) NOT NULL, mail VARCHAR(50) NOT NULL, PRIMARY KEY (id), CHECK (LENGTH(fname) > 30) ); The insert statement: INSERT INTO user VALUES (null, 'user', 'Fname', 'Lname', '[email protected]'); The length of the string in the fname column should be too short, but it's inserted anyway. I'm pretty sure I'm missing something basic here.

• How can I have a serializable struct that wraps it's self as an int32 implicitly? in C#?

  - by firoso

  Long story short, I have a struct (see below) that contains exactly one field: private int value; I've also implemented implicit conversion operators: public static implicit operator int(Outlet val) { return val.value; } public static implicit operator Outlet(int val) { return new Outlet(val); } I've implemented all of the following : IComparable, IComparable<Cart>, IComparable<int>, IConvertible, IEquatable<Cart>, IEquatable<int>, IFormattable I'm at a point where I really have no clue why, but whenever I serialize this object, I get no value. For instance, with XmlSerialization: <Outlet /> Also, I'm not solely concerned about XmlSerialization, I'm concerned about ALL serialization (binary for instance) How can I ensure that this serializes properly? NOTE: I did this because mapping an int,int dictionary seemed rather poorly typed to me when explicit objects with validation behavior were desired.

• Many-To-Many dimensional model

  - by Mevdiven

  Folks, I have a dimension table called DIM_FILE which holds information of the files we received from customers. Each file has detail records which constitutes my FACT table, CUST_DETAIL. In the main process, file is gone through several stages and each stage tags a status to it. Long in a short, I have many-to-many relationship. Any ideas around star schema dimensional modeling. A customer record only belong to a single file and a file can have multiple statuses. FACT ---- CustID FileID AmountDue DIM_FILE -------- FileID FileName DateReceived FILE_STATUS ----------- FileID StatusDateTime StatusCode

• What features are important in a programming language for beginners?

  - by NoMoreZealots

  I was talking with some of the mentors in a local robotics competition for 7th and 8th level kids. The robot was using PBASIC and the parallax Basic Stamp. One of the major issues was this was short term project that required building the robot, teaching them to program in PBASIC and having them program the robot. All in only 2 hours or so a week over a couple months. PBASIC is kinda nice in that it has built in features to do everything, but information overload is possible to due this. My thought are simplicity is key. When you have kids struggling to grasp: if X10 then There is not much point in throwing "proper" object oriented programming at them. What are the essentials needed to foster an interest in programming?

• OpenGL: Textured Primitives + High Framerate

  - by James D

  Short version: What's the best practice going forward for efficiently rendering large numbers of independent texture-mapped, lighted 2D/3D primitives (circles, rects, etc.) in OpenGL? For example: a typical particle system using billboarded quads/triangles, point sprites, or whatever other technique, with blending. Because after reading this thread on the messiness of OpenGL versioning/deprecation I'm starting to have my doubts. My specific question is not the ABCs of displaying primitives in OpenGL, but rather how to do so efficiently in post-deprecation (or pre-deprecation) OpenGL, in a way that's going to be compatible with a wide range of commodity hardware and in a way that's not going to break or itself get deprecated, five years down the line. Thanks!

• ASP.NET How expensive is it to call an Application Variable many times?

  - by Matias Nino

  The short of it is: Is it costly to check an Application Variable such as Application("WebAppName") more 10-20 times each time a page loads? Background: (feel free to critique) Some includes in my site contain many links and images which cannot use relative urls due to their inclusion in different paths. Hence these includes contain frequent instances of <img src="<%=Application("Webroot")%>images\image.gif"> Is it expensive to keep calling an Application variable like this? Should I just put the Application value in some local variable to use where needed? IMPORTANT NOTE: I need my webapp to run fine on a server whether it be in the root web ("/") or in a virtual subweb ("/app"). Thanks in advance for any wisdom shared.

• Editing a BrowserField's History

  - by Woody

  I have a BrowserField in my app, which works great. It intercept NavigationRequests to links on my website which go to external sites, and brings up a new windows to display those in the regular Browser, which also works great. The problem I have is that if a user clicks a link to say "www.google.com", my app opens that up in a new browser, but also logs it into the BrowserHistory. So if they click back, away from google, they arrive back at my app, but then if they hit back again, the BrowserHistory would land them on the same page they were on (Because going back from Google doesn't move back in the history) I've tried to find a way to edit the BrowserField's BrowserHistory, but this doesn't seem possible. Short of creating my own class for logging the browsing history, is there anything I can do? If I didn't do a good job explaining the problem, don't hesitate for clarification. Thanks

• Ultra-Portable Laptop or Tablet PC for Development and Sketching

  - by Nelson LaQuet

  I am a software developer that primarily writes in PHP, [X]HTML, CSS, Javascript, C# and C++. I use Eclipse for web development, Visual Studio 2008 for C++ and C# work, TortoiseSVN, Subversion server for local repositories, SQL Server Express, Apache and MYSQL. I also use Office 2007 for word processing and spreadsheets and use Vista Ultimate 64 as my primary operating system. The only other things I do on my laptop are watch movies, surf the internet and listen to music. I currently have a Acer Aspire 5100 (1.4 GHz AMD Turion X2, 2 GB of RAM and a 15.4" screen). This thing does not cut it in performance or portability, and in addition, my DVD drive failed. And before anybody posts about vista: I have had XP Professional 32 on it for the last two years, and recently upgraded to Vista 64. It is actually faster (with areo disabled) then XP; so it is not the OS that is causing the laptop to be slow. I usually sketch a lot, for explaining things, developing user interfaces and software architecture. Because of my requirements, I was thinking about a Lenovo X61 Tablet PC. It outperforms my current laptop, is significantly more portable, and... is a tablet. My question is: do any other software developers use this (or other tablets) for programming? Does it help to be able to sketch on the computer itself? And is it capable of being a good development machine? Will it handle the above software listed? If not, what is the best ultra-portable laptop that is good for programming? Or are ultra-portable laptops even good for programming? I could manage with my 15.4" screen, but am spoiled by my two 19" at my home desktop and my job's workstation.

• Forumotion profile customization using jQuery based on URL

  - by Harvengure

  The idea is have a jQuery snippet (I like Jquery...I can understand it better then regular javascript) that will detect that when it has been run on a profile with a url such as "http://customize.forum-motion.com/profile.forum?mode=viewprofile&u=1" (just as an example)...then upon detecting that it is a url of a profile...fetch data from a specific (and most likely hidden) element before wrapping that data in css tags and appending it to the heady of the current document. In short I'm trying to figure out how to make a sort of profile customization system where users can create their own css. The biggest problem I am having so far is figuring out how to make it so that the snippet can figure out what URL its being run on. Is there a function that can do this in jQuery at all?

• .net IHTTPHandler Streaming SQL Binary Data

  - by Yisman

  Hello everybody I am trying to implement an ihttphandeler for streaming files. files may be tiny thumbnails or gigantic movies the binaries r stored in sql server i looked at a lot of code online but something does not make sense isnt streaming supposed to read the data piece by piece and move it over the line? most of the code seems to first read the whole field from mssql to memory and then use streaming for the output writing wouldnt it b more eficient to actually stream from disk directly to http byte by byte (or buffered chunks?) heres my code so far but cant figure out the correct combination of the sqlreader mode and the stream object and the writing system Public Sub ProcessRequest(ByVal context As HttpContext) Implements IHttpHandler.ProcessRequest context.Response.BufferOutput = False Dim FileField=safeparam(context.Request.QueryString("FileField")) Dim FileTable=safeparam(context.Request.QueryString("FileTable")) Dim KeyField=safeparam(context.Request.QueryString("KeyField")) Dim FileKey=safeparam(context.Request.QueryString("FileKey")) Using connection As New SqlConnection(ConfigurationManager.ConnectionStrings("Main").ConnectionString) Using command As New SqlCommand("SELECT " & FileField & "Bytes," & FileField & "Type FROM " & FileTable & " WHERE " & KeyField & "=" & FileKey, connection) command.CommandType = Data.CommandType.Text enbd using end using end sub please be aware that this sql command also returns the file extension (pdf,jpg,doc...) in the second field of the query thank you all very much

• Efficient way to ASCII encode UTF-8

  - by Andreas Gohr

  I'm looking for a simple and efficient way to store UTF-8 strings in ASCII-7. With efficient I mean the following: all ASCII chars in the input should stay ASCII chars in the output the resulting string should be as short as possible the operation needs to be reversable without any data loss there should be no restriction on the input length the whole UTF-8 range should be allowed My first idea was to use Punycode (IDNA) as it fits the first three requirements, but it fails at the last two. Can anyone recommend an alternative encoding scheme? Even better if there's some code available to look at.

• Getting past Salesforce trigger governors

  - by Jake

  I'm trying to write an "after update" trigger that does a batch update on all child records of the record that has just been updated. This needs to be able to handle 15k+ child records at a time. Unfortunately, the limit appears to be 100, which is so far below my needs it's not even close to acceptable. I haven't tried splitting the records into batches of 100 each, since this will still put me at a cap of 10k updates per trigger execution. (Maybe I could just daisy-chain triggers together? ugh.) Does anyone know what series of hoops I can jump through to overcome yet another ridiculously short-sighted limitation by this awful development "platform"?

• mySQL Left Join on multiple tables

  - by Jarrod

  Hi I'm really struggling with this query. I have 4 tables (http://oberto.co.nz/db-sql.png): Invoice_Payement, Invoice, Client and Calendar. I'm trying to create a report by summing up the 'paid_amount' col, in Invoice_Payment, by month/year. The query needs to include all months, even those with no data There query needs the condition (Invoice table): registered_id = [id] I have tried with the below query, which works, but falls short when 'paid_date' does not have any records for a month. The outcome is that month does not show in the results I added a Calendar table to resolved this but not sure how to left join to it. SELECT MONTHNAME(Invoice_Payments.date_paid) as month, SUM(Invoice_Payments.paid_amount) AS total FROM Invoice, Client, Invoice_Payments WHERE Client.registered_id = 1 AND Client.id = Invoice.client_id And Invoice.id = Invoice_Payments.invoice_id AND date_paid IS NOT NULL GROUP BY YEAR(Invoice_Payments.date_paid), MONTH(Invoice_Payments.date_paid) Please see the above link for a basic ERD diagram of my scenario. Thanks for reading. I've posted this Q before but I think I worded it badly.

• Artificial Intelligence in online game using Google App Engine

  - by Hortinstein

  I am currently in the planning stages of a game for google app engine, but cannot wrap my head around how I am going to handle AI. I intend to have persistant NPCs that will move about the map, but short of writing a program that generates the same XML requests I use to control player actions, than run it on another server I am stuck on how to do it. I have looked at the Task Queue feature, but due to long running processes not being an option on the App engine, I am a little stuck. I intend to run multiple server instances with 200+ persistant NPC entities that I will need to update. Most action is slowly roaming around based on player movements/concentrations, and attacking close range players...(you can probably guess the type of game im developing)

• 'script/console test' with spork and rspec not loading the whole environment?

  - by TheDeeno

  I'm trying to load up console to interact with some of my rspec mocking helpers. I expected that running script/console test would load an env similar to when I run spec. However, this doesn't appear to be the case. It looks like spec_helper is never loaded. Or, if it is, it's not actually running through the logic because spork has polluted it a bit. In short, is there a quick and easy way to get an interactive rspec party going?

• Why is only the suffix of work_index hashed?

  - by Jaroslav Záruba

  I'm reading through the PDF that Brett Slatkin has published for Google I/O 2010: "Data pipelines with Google App Engine": http://tinyurl.com/3523mej In the video (the Fan-in part) Brett says that the work_index has to be a hash, so that 'you distribute the load across the BigTable': http://www.youtube.com/watch?v=zSDC_TU7rtc#t=48m44 ...and this is how work_index is created: work_index = '%s-%d' % (sum_name, knuth_hash(index)) ...which I guess creates something like 'mySum-54657651321987' I do understand the basic idea, but is why only one half of work_index is hashed? Is it important to hash only part of it leaving the suffix out? Would it be wrong to do md5('%s-%d' % (sum_name, index)) so that the hash would be like '6gw8....hq6' ? I'm Java guy so I would use md5 to hash, which means I get id like 'mySum' + 32 characters. (Obviously I want my ids/keys to be as short as possible here.) If I could hash the whole string my id would be just 32 chars. Or would you suggest to use something else to do the hashing with?

• Rails routing/polymorphism issue - how to model the following

  - by 46and2

  Hi all, I have an app where a 'user' belong to a 'client' or a 'vendor' (and client and vendor has_many users). In the admin namespace, I want to administer these users - so an admin would choose a client or a vendor, then nav to that client's or vendor's users. My question is, short of making the user model polymorphic, how could I model/route this? Here is what I have in terms of routing: map.namespace :admin do |admin| admin.resources :clients admin.resources :vendors end I know I could do something like: map.namespace :admin do |admin| admin.resources :clients do |client| client.resources :users admin.resources :vendors do |vendor| vendor.resources :users end end But the above would definitely need me to treat the User as polymorphic. I'm just wondering what you would recommend or what my options are. Thanks.

• Maven test failure xml FileNotFoundException

  - by James

  My Maven build is failing on Hudson with a FileNotFoundException, I do not get the same failure through NetBeans. The FileNotFoundException is for some xml files in the same packages as my test classes themselves. It would appear these are not getting copied as part of the build in the same way the class files are. Do I have to add something to my POM for the xml files to be copied? If any more information is required please let me know, I wanted to keep the question short incase it was something simple.

• Use of (non) qualified names

  - by AProgrammer

  If I want to use the name baz defined in package foo|bar|quz, I've several choices: provide fbq as a short name for foo|bar|quz and use fbq|baz use foo|bar|quz|baz import baz from foo|bar|quz|baz and then use baz (or an alias given in the import process) import all public symbols from foo|bar|quz|baz and then use baz For the languages I know, my perception is that the best practice is to use the first two ways (I'll use one or the other depending on the specific package full name and the number of symbols I need from it). I'd use the third only in a language which doesn't provide the first and hunt for supporting tools to write the import statements. And in my opinion the fourth should be reserved to package designed with than import in mind, for instance if all exported symbols start with a prefix or contains the name of the package. My questions: what is in your opinion the best practice for your favorite languages? what would you suggest in a new language? what would you suggest in an old language adding such a feature?

• SVN Best practice for a "branch" of your main product ?

  - by Steffen

  At my job we develop websites - however now we're going to make a "whitelabelled" version of a site, which basically means it's the same site, however with a different logo and hosted on a different domain. Also it'll have minor graphical differences, but overall the engine is the same. My initial thought for keeping this in SVN, was to just make a branch for it - however I'm not quite certain if this could give me trouble later on. Normally I keep my branches somewhat short lived - mainly used for developing a new feature, without disturbing trunk. We need to be able to merge trunk changes into this "whitelabel" version, which I why I thought about branching it in the first place. So what's the best way to archive this ?
