• Database design - alternatives for Entity Attribute Value (AEV)

  - by Bob

  Hi, see http://stackoverflow.com/questions/695752/product-table-many-kinds-of-product-each-product-has-many-parameters for similar topic. My question: i want to design a database, that will be used for a production facility of different types of products where each product has its own (number of) parameters. because i want the serial numbers to be in one tabel for overview purposes i have a problem with these different paraeters . One solution could be AEV, but it has its downsides, certainly because we have +- 5 products with every product +- 20.000 serial numbers (records). it looks a bit overkill to me... I just don't know how one could design a database so that you have an attribute in a mastertable that says: 'hey, you could find details of this record in THAT detail-table". 'in a way that you qould easely query the results) currenty i am using Visual Basic & Acces 2007. but i'm going to Visual Basic & MySQL. thanks for your help. Bob

• forcing Management Studio to use alter table instead of drop/recreate

  - by marco

  Hi! I'm wondering if is there a way to force MSSQL Management Studio to produce a script like this: ALTER TABLE Mytable ADD MyCol bit NOT NULL CONSTRAINT MyColDefault DEFAULT 0 WITH VALUES ALTER TABLE [dbo].Mytable ALTER COLUMN MyCol2 int NULL GO when I alter a very simple property of a column on a table. If I do this in the designer and ask for the produced script, the script doesn't do such simple tasks, but instead copies all the data in a tmp table, drops the original table, renames the tmp table with the original table name. And, of course, drops and recreates every constraint and relationships. Is there any option I can change to change this behaviour? Or, this may be possible, is there some danger I don't see in using the simple ALTER TABLE above? thanks.

• Bitwise Shifting in C

  - by user313943

  I've recently decided to undertake an SMS project for sending and receiving SMS though a mobile. The data is sent in PDU format - I am required to change ASCII characters to 7 bit GSM alphabet characters. To do this I've come across several examples, such as http://www.dreamfabric.com/sms/hello.html This example shows Rightmost bits of the second septet, being inserted into the first septect, to create an octect. Bitwise shifts do not cause this to happen, as will insert to the left, and << to the right. As I understand it, I need some kind of bitwise rotate to create this - can anyone tell me how to move bits from the right handside and insert them on the left? Thanks,

• Chrome Extension Manifest 'Matches'

  - by Aristotle

  I'm trying my hands at a simple Chrome Extension, but am running into a problem with providing a value for the matches array in my content_scripts. { "name": "My Extension", "version": "1.0", "description": "My Extension Experiment", "browser_action": { "default_icon": "icon.png", "default_title": "Ext", "default_popup": "popup.html" }, "content_scripts": { "matches": ["http://*"], "js": ["scripts.js"] } } When I try to load this extension into Chrome, I get the following message: Could not load extension from 'C:\Users\foo\Desktop\Extensions\bar'.Invalid value for 'content_scripts'. I cannot see what is "invalid" about my value though. What I'm trying to do is match every URL, so my extension can manipulate the DOM (via javascript within scripts.js) of any page it is ran on. Am I missing something, going about this all wrong, or what? update After posting this question, I did notice that the Google example was slightly different than mine, so I modified my code a bit to reflect their syntax: "content_scripts": [{ "matches": ["http://*"], "js": ["scripts.js"] }] That being said, I still get the following error when trying to load my extension: Could not load extension from 'C:\Users\foo\Desktop\Extensions\bar'. Invalid value for 'content_scripts[0].matches[0]'.

• Accidentally deleted /opt/local/bin without backup. Any help?

  - by Aaron

  Hi all, I'm on a Mac OS X 10.5.8 I was recently uninstalling mysql5 from /opt/local/bin. I typed: rm -rf /opt/local/bin mysql* instead of rm -rf /opt/local/bin/mysql* This deleted my entire /opt/local/bin directory which puts me in a bit of a bind. Is there any way to recover these files? If not, I have a friend that is using a similar set of programs, would it be possible to use the contents of his folder? If I end up needing to re-install everything in this folder, what is the best way to go about doing this? Thanks in advance!

• Rails: How to produce 404 or redirect upon undesired url exploitation?

  - by Baby Diego

  I want to hide the urls for editing users and their profiles behind safer and meaningful urls. For instance, I want /user/13/edit to be /settings/account and /user/13/profile/edit to be /settings/profile. I managed to achieve that, but for that I had to load the user information from the current_user bit from the session. Like so: # users_controller def edit @user = current_user end # profiles_controller def edit @user = current_user @profile = @user.profile end But now, since I can't compare @user.id from the params with the current_user in the session, how can I stop the old urls (/user/13/edit and /user/13/profile/edit) from being exploitable? They always load the forms for the current user, so there's no harm done, but I'd be more comfortable if they just produced a 404 error or something. Thanks in advance.

• Microsoft SQL Server 2008 - 99% fragmentation on non-clustered, non-unique index

  - by user550441

  I have a table with several indexes (defined below). One of the indexes (IX_external_guid_3) has 99% fragmentation regardless of rebuilding/reorganizing the index. Anyone have any idea as to what might cause this, or the best way to fix it? We are using Entity Framework 4.0 to query this, the EF queries on the other indexed fields about 10x faster on average then the external_guid_3 field, however an ADO.Net query is roughly the same speed on both (though 2x slower than the EF Query to indexed fields). Table id(PK, int, not null) guid(uniqueidentifier, null, rowguid) external_guid_1(uniqueidentifier, not null) external_guid_2(uniqueidentifier, null) state(varchar(32), null) value(varchar(max), null) infoset(XML(.), null) -- usually 2-4K created_time(datetime, null) updated_time(datetime, null) external_guid_3(uniqueidentifier, not null) FK_id(FK, int, null) locking_guid(uniqueidentifer, null) locked_time(datetime, null) external_guid_4(uniqueidentifier, null) corrected_time(datetime, null) is_add(bit, not null) score(int, null) row_version(timestamp, null) Indexes PK_table(Clustered) IX_created_time(Non-Unique, Non-Clustered) IX_external_guid_1(Non-Unique, Non-Clustered) IX_guid(Non-Unique, Non-Clustered) IX_external_guid_3(Non-Unique, Non-Clustered) IX_state(Non-Unique, Non-Clustered)

• Only compiles as an array of pointers, not array of arrays

  - by Dustin

  Suppose I define two arrays, each of which have 2 elements (for theoretical purposes): char const *arr1[] = { "i", "j" }; char const *arr2[] = { "m", "n" }; Is there a way to define a multidimensional array that contains these two arrays as elements? I was thinking of something like the following, but my compiler displays warnings about incompatible types: char const *combine[][2] = { arr1, arr2 }; The only way it would compile was to make the compiler treat the arrays as pointers: char const *const *combine[] = { arr1, arr2 }; Is that really the only way to do it or can I preserve the type somehow (in C++, the runtime type information would know it is an array) and treat combine as a multidimensional array? I realise it works because an array name is a const pointer, but I'm just wondering if there is a way to do what I'm asking in standard C/C++ rather than relying on compiler extensions. Perhaps I've gotten a bit too used to Python's lists where I could just throw anything in them...

• how do you load files in windows phone 7? using XNA

  - by matt

  do you seriously have to make your own content pipeline project for every single type of file you want to load? Microsoft just seem to be pretending that the iphone doesn't exist (even though they are now paying devs to port between them). I'm trying to port my game from the iphone to winmo7, and I already have a nice asset pipeline set up for exporting textures in the exact format we want (16 bit fmts ect) I just want to be able to open a file and read it, just like I would on any other platform. I have tried System.IO.File.OpenText("atextfile.txt"), but it says that function is "RESTRICTED!!!!" I have tried just adding the txt file to the content project, setting its properties to "content" and "copy always" and then trying to open it doing this.Content.Load("atextfile.txt"); with and without the extension, says it can't find the file. EDIT: FYI, i'm using XNA, not Silverlight

• Creating a new project from a project skeleton using git

  - by asciitaxi

  In order to get a new django project up and running faster, I'd like to maintain a separate "project skeleton" on which I base all my new projects. It would be great if, as I improved the skeleton, I could bring those improvements into my active projects. How can I accomplish this with git? So, maybe in my remote git repository machine I would have 1 repo for each project and one for the skeleton? proj-A-repo proj-B-repo skeleton-repo If I want to create a new proj-C locally based on the skeleton, then push my local changes up to the remote server in a new repo called proj-C-repo, how might I do this? I've read through quite a bit of git documentation, but I'm confused about how to go about this. Do I need to clone the skeleton, or create an empty repo and then track a remote branch, or something else?

• htaccess, remove text from url

  - by Keiron Lowe

  Here is the email from the client explaining what he is trying to do, we have spent hours trying to sort out this problem but cannot find a solution that works. I am trying to correct a problem with my blog and google “not found” URLs. I thought it might be very simple to correct (!ha!) This is my line of code; RewriteCond %{THE_REQUEST} ^www.uk-domestic-cleaning.com/wpblog/tag/?(.*)/HomeMaid%20Domestic%20Cleaning$ RewriteRule ^wpblog\/tag\/?(.*)\/HomeMaid%20Domestic%20Cleaning$ "http\:\/\/www\.uk\-domestic\-cleaning\.com\/wpblog\/tag\/$1" [R=301,L] What I am trying to do is any request to */wplog/tag/ “anything here”/HomeMaid Domestic Cleaning To strip the “HomeMaid Domestic Cleaning” bit off the end, but leave the rest of the request intact, which will then be a valid request. Any idea's guys?

• SQLite doesn't have booleans or date-times.

  - by DanM

  I've been thinking about using SQLite for my next project, but I'm concerned that it seems to lack proper datetime and bit data types. If I use DbLinq (or some other ORM) to generate C# classes, will the data types of the properties be "dumbed down"? Will date-time data be placed in properties of type string or double? Will boolean data be placed in properties of type int? If yes, what are the implications? I'm envisioning a scenario where I need to write a whole second layer of classes with more specific data types and do a bunch of transformations and casts, but maybe it's not as bad as I fear. If you have any experience with this or a similar scenario, how did you handle it?

• Is there an exponent operator in C#?

  - by Charlie

  For example, does an operator exist to handle this? float Result, Number1, Number2; Number1 = 2; Number2 = 2; Result = Number1 (operator) Number2; In the past the ^ operator has served as an exponential operator in other languages, but in C# it is a bit-wise operator. Do I have to write a loop or include another namespace to handle exponential operations? If so, how do I handle exponential operations using non-integers?

• parse/collator for php

  - by dramatic

  I'm pretty much a newbie at php (at the "install an app and try to tweak it a bit" stage). Is there a tool anywhere which can take a script which is spread over many files and show you all the code which is processed (for a given set of arguments passed to the script) in a single output? For example, I want to make a call to zen cart from a script in a different language, which returns a category listing without any surrounding page. So I want to be able to trace what the actual process is to generate that then strip off all the unwanted bits to create a custom script.

• How to check code is compatible with Windows 7

  - by Julen

  Hello, We are developing using Visual C# 2008 Express a program based on WPF under Windows XP machines (32 bits). The thing is that we have tried to run the program in two Windows 7 machines, one is 32 bits Windows 7 and the other is 64 bits Windows 7. Under Windows XP everything is fine. In Windows 7 machine, it launches in the 32 bits version altough there is an error when running one functionality (it does not happen in XP). In W7 64 bits it even does not launch. Is this normal? Is not possible to run 32 bit programs under W7 64-bits,even if they execute slower?? How can we check the code is compatible with Windows 7? Thank you very much in advance. Julen.

• Problems with .net and toolbar, menu & status bar rendermode (blue) and standard form (grey)

  - by Andrew White

  Hiya, I'm a bit of a newbie to .NET so please ignore my ignorance. If you look at the above image (a complete prototype, ignore black bits :)) you will see lovely menus, toolbars & statusbars all using windows XP render mode and in a funky blue. Look at the form, labels, checkboxes and other buttons and you see horrible old school windows grey. These components don't have a render mode. My question: is there any way to show everything in XP style or do I have to chose new components? Thx. A.

• How should I deal with persisting an Android WebView if my activity gets destroyed while showing ano

  - by Shaun Crampton

  Hi, I'm building an Android application that's based around an enhanced WebView (based on PhoneGap). I've enhanced the WebView so that from JavaScript running inside you can invoke the native contact picker to choose a phone number (which may be supplied by Facebook for example). The problem I have is that the native contact picker runs in an activity in another process and the Android docs say that while another activity is open my activity may get destroyed due to memory constraints. I haven't actually seen this happen in my application but if it did then I'm guessing my WebView's state would be destroyed and the code that was waiting for the picked contact would be terminated. It seems a bit crazy that the activity requesting a contact could be destroyed while the contact picker is open. Does anyone know if that does indeed happen? Is there a way to persist the state of the WebView if it does? Thanks, -Shaun

• Is php fileinfo sufficient to prevent upload of malicious files?

  - by Scarface

  Hey guys, I have searched around a bit, and have not really found a professional type response to how to have secure fileupload capability so I wanted to get the opinion of some of the experts on this site. I am currently allowing upload of mp3s and images, and while I am pretty confident in preventing xss and injection attacks on my site, I am not really familiar with fileupload security. I basically just use php fileinfo and check an array of accepted filetypes against the filetype. For images, there is the getimagesize function and some additional checks. As far as storing them, I just have a folder within my directory, because I want the users to be able to use the files. If anyone could give me some tips I would really appreciate it.

• UITableView with Core Data and fetchedResultsController - don't want to call it at start up

  - by zebulon

  Hi all, I started with the Navigation-based application. I have a UITableView that shows the content fetched from CoreData - using the - (NSFetchedResultsController *)fetchedResultsController from the template. The thing is that I don't want to fill the TableView with the results at the start-up, instead I want to fill the TableView with the results from a search. In my app I have an UITextField, where the user can type a string. And from that string, using predicate, I want to fill the UITableView with the results. In other words, at start-up, the UITableView should be empty and later filled with the search-results. Does anyone have an idea on how to accomplish this? Thanks in advance! EDIT: Solved it by moving out if (![fetchedResultsController_ performFetch:&error]) { and calling it later. I feel a bit stupid ;)

• When compiling programs to run inside a VM, what should march and mtune be set to?

  - by Russ

  With VMs being slave to whatever the host machine is providing, what compiler flags should be provided to gcc? I would normally think that -march=native would be what you would use when compiling for a dedicated box, but the fine detail that -march=native is going to as indicated in this article makes me extremely wary of using it. So... what to set -march and -mtune to inside a VM? For a specific example... My specific case right now is compiling python (and more) in a linux guest inside a KVM-based "cloud" host that I have no real control over the host hardware (aside from 'simple' stuff like CPU GHz m CPU count, and available RAM). Currently, cpuinfo tells me I've got an "AMD Opteron(tm) Processor 6176" but I honestly don't know (yet) if that is reliable and whether the guest can get moved around to different architectures on me to meet the host's infrastructure shuffling needs (sounds hairy/unlikely). All I can really guarantee is my OS, which is a 64-bit linux kernel where uname -m yields x86_64.

• ASP control event handler not firing on postback?

  - by Polaris878

  Hello, I have a control which has an ImageButton which is tied to an OnClick event... Upon clicking this control, a postback is performed and the event handler is not called. AutoEventWireup is set to true, and I've double checked spelling etc.... We haven't touched this control in over a year and it has been working fine until a couple of weeks ago. We have made changes to controls which load this control... so I'm wondering, what kind of changes could we have made to stop this event handler from being called? There is quite a bit of Javascript going on, so this could be the culprit too... Thanks

• Move a sequential set of commits from one (local) branch to another

  - by jpswain09

  Is there a way to move a sequential set of commits from one (local) branch to another? I have searched quite a bit and still haven't found a clear answer for what I want to do. For example, say I have this: master A---B---C \ feature-1 M---N---O---P---R---Q And I have decided that the last 3 commits would be better off like this: master A---B---C \ feature-1 M---N---O \ f1-crazy-idea P---R---Q I know I can do this, and it does work: $ git log --graph --pretty=oneline (copying down sha-1 ID's of P, R, Q) $ git checkout feature-1 $ git reset --hard HEAD^^^ $ git checkout -b f1-crazy-idea $ git cherry-pick <P sha1> $ git cherry-pick <R sha1> $ git cherry-pick <Q sha1> I was hoping that instead there would be a more concise way to do this, possibly with git rebase, although I haven't had much luck. Any insight would be greatly appreciated. Thanks, Jamie

• Executing commands on a Unix box from ASP .NET

  - by StefanE

  I'm in process to create a few utilities for my team to make life a bit easier working with our Unix boxes(most of them Solaris based). For example I'm creating a ASP .NET page to display the output of TOP. Also plan to be able to restart processes with the KILL -15 command. Now I wonder if there is any nice modules out the do the work for me or am I better off just going ahead with my own SSH communication? It would of course make sense building the app on the unix box directly but I'm not able to do this.

• Entity Aspect (in Spring)

  - by niklassaers

  Hi guys, I'm having a bit of a problem defining my aspects. I've got a bunch of entities that I'd like to profile the get-methods in, so I've written the following pointcut and method @Pointcut("execution(* tld.myproject.data.entities.*.get*()") public void getEntityProperty() {} @Around("getEntityProperty()") public Object profileGetEntityProperty(ProceedingJoinPoint pjp) throws Throwable { long start = System.currentTimeMillis(); String name = pjp.getSignature().getName(); Object output = pjp.proceed(); long elapsedTime = System.currentTimeMillis() - start; if(elapsedTime > 100) System.err.println("profileGetEntityProperty: Entity method " + name + " execution time: " + elapsedTime + " ms."); return output; } I've got weaving turned on in my configuration, and aspects weaving into the business layer work just fine. Is my pointcut correctly written? Or is there something about entities that make them non-weavable? (my entity is prefixed with @Entity before the class definition) Cheers Nik

• In WPF using a ListView is there an elegant way to auto resize items?

  - by Justin

  I recently wrote, my first, WPF application that has a list of items that are polled from a web-serivce. The items are displayed/data-bound in a ListView via a GridView. A background thread periodically polls the web-serivce and updates the list. If, say, I had three items initially bound to the ListView that simply display a description and the three descriptions where something like: - ProjectA - ProjectB - ProjectC Later a new item is added with a description of 'AReallyReallyLongProjectName', I would end up with a list like: - ProjectA - ProjectB - ProjectC - AReallyR The GridViewColumn would not update it's width and would subsequently cut off any new items that extended the original width. I added this bit of code which forces the column to resize, but it just seems a little hacky. (Just seems weird to set a width just to set it back to nothing to force the resize) if(gridView != null) { foreach(var column in gridView.Columns) { if (double.IsNaN(column.Width) column.Width = column.ActualWidth; column.Width = double.NaN; } } Is there a better, more elegant solution, to accomplish this same thing?
