• Using fonts that aren't on iPhone

  - by 4thSpace

  I'd like to use some fonts that aren't part of the iPhone OS. I've seen games that use non standard fonts. I can install the fonts, create images for each one in Photoshop and then use those images in the iPhone app. However, I don't think that is a practical way to go. If the color or tint needs to be adjusted (because of background) or size, I'll have to redesign every font I'm using. Is there a better way to do this? I read this http://stackoverflow.com/questions/360751/can-i-embed-a-custom-font-in-an-iphone-application and downloaded the open source font label app. However, it crashes most of the time when I try using particular fonts. In regards to the last comment about using UIFont with the fontWithName:size, that certainly doesn't work. Your font variable will be nil. Listing all available fonts reveals why - none of the custom fonts are in the list. I've also read http://stackoverflow.com/questions/566054/how-do-i-include-a-font-with-my-iphone-application, which definitely does not work. Same as last comment in above link.

• How do I bind to a custom view in Cocoa using Xcode 4?

  - by Newt

  I'm a beginner when it comes to writing Mac apps and working with Cocoa, so please forgive my ignorance. I'm looking to create a custom view, that exposes some properties, which I can then bind to an NSObjectController. Since it's a custom view, the Bindings Inspector obviously doesn't list any of the properties I've added to the view that I can then bind to using Interface Builder. After turning to the Stackoverflow/Google for help, I've stumbled across a couple of possible solutions, but neither seem to be quite right for my situation. The first suggested creating an IBPlugin, which would then mean my bindings would be available in the Bindings Inspector. I could then bind the view to the controller using IB. Apparently IBPlugins aren't supported in Xcode 4, so that one's out the window. I'm also assuming (maybe wrongly) that IBPlugins are no longer supported because there's a better way of doing such things these days? The second option was to bind the controller to the view programmatically. I'm a bit confused as to exactly how I would achieve this. Would it require subclassing NSObjectController so I can add the calls to bind to the view? Would I need to add anything to the view to support this? Some examples I've seen say you'd need to override the bind method, and others say you don't. Also, I've noticed that some example custom views call [self exposeBinding:@"bindingName"] in the initializer. From what I gather from various sources, this is something that's related to IBPlugins and isn't something I need to do if I'm not using them. Is that correct? I've found a post on Stackoverflow here which seems to discuss something very similar to my problem, but there wasn't any clear winner as to the best answer. The last comment by noa on 12th Sept seems interesting, although they mention you should be calling exposeBinding:. Is this comment along the right track? Is the call to exposeBinding really necessary? Apologies for any dumb questions. Any help greatly appreciated.

• R plotting multiple histograms on single plot to .pdf as a part of R batch script

  - by Bryce Thomas

  I am writing R scripts which play just a small role in a chain of commands I am executing from a terminal. Basically, I do much of my data manipulation in a Python script and then pipe the output to my R script for plotting. So, from the terminal I execute commands which look something like $python whatever.py | R CMD BATCH do_some_plotting.R. This workflow has been working well for me so far, though I have now reached a point where I want to overlay multiple histograms on the same plot, inspired by this answer to another user's question on Stackoverflow. Inside my R script, my plotting code looks like this: pdf("my_output.pdf") plot(hist(d$original,breaks="FD",prob=TRUE), col=rgb(0,0,1,1/4),xlim=c(0,4000),main="original - This plot is in beta") plot(hist(d$minus_thirty_minutes,breaks="FD",prob=TRUE), col=rgb(1,0,0,1/4),add=T,xlim=c(0,4000),main="minus_thirty_minutes - This plot is in beta") Notably, I am using add=T, which is presumably meant to specify that the second plot should be overlaid on top of the first. When my script has finished, the result I am getting is not two histograms overlaid on top of each other, but rather a 3-page PDF whose 3 individual plots contain the titles: i) Histogram of d$original ii) original - This plot is in beta iii) Histogram of d$minus_thirty_minutes So there's two points here I'm looking to clarify. Firstly, even if the plots weren't overlaid, I would expect just a 2-page PDF, not a 3-page PDF. Can someone explain why I am getting a 3-page PDF? Secondly, is there a correction I can make here somewhere to get just the two histograms plotted, and both of them on the same plot (i.e. 1-page PDF)? The other Stackoverflow question/answer I linked to in the first paragraph did mention that alpha-blending isn't supported on all devices, and so I'm curious whether this has anything to do with it. Either way, it would be good to know if there is a R-based solution to my problem or whether I'm going to have to pipe my data into a different language/plotting engine.

• Guidance required: FIrst time gonna work with real high end database (size = 50GB).

  - by claws

  I got a project of designing a Database. This is going to be my first big scale project. Good thing about it is information is mostly organized & currently stored in text files. The size of this information is 50GB. There are going to be few millions of records in each Table. Its going to have around 50 tables. I need to provide a web interface for searching & browsing. I'm going to use MySQL DBMS. I've never worked with a database more than 200MB before. So, speed & performance was never a concern but I followed things like normalization & Indexes. I never used any kind of testing/benchmarking/queryOptimization/whatever because I never had to care about them. But here the purpose of creating a database is to make it quickly searchable. So, I need to consider all possible aspects in design. I was browsing archives & found: http://stackoverflow.com/questions/1981526/what-should-every-developer-know-about-databases http://stackoverflow.com/questions/621884/database-development-mistakes-made-by-app-developers I'm gonna keep the points mentioned in above answers in mind. What else should I know? What else should I keep in mind?

• What is better: Developing a Web project in MVC or N -Tier Architecture?

  - by Starx

  I have asked a similar question before and got an convincing answer as well? http://stackoverflow.com/questions/2843311/what-is-difference-of-developing-a-website-in-mvc-and-3-tier-or-n-tier-architectu Due to the conclusion of this question I started developing projects in N-tier Architecture. Just about an hour ago, I asked another question, about what is the best design pattern to create interface? There the most voted answer is suggesting me to use MVC architecture. http://stackoverflow.com/questions/2930300/what-is-the-best-desing-pattern-to-design-the-interface-of-an-webpage Now I am confused, First post suggested me that both are similar, just a difference that in N-tier, the tier are physically and logically separated and one layer has access to the one above and below it but not all the layers. I think ASP.net used 3 Tier architecture while developing applications or Web applications. Where as frameworks like Zend, Symphony they use MVC. I just want to stick to a pattern that is best suitable for WebProject Development? May be this is a very silly confusion? But if someone could clear this confusion, that would be very greatful?

• Efficient (basic) regular expression implementation for streaming data

  - by Brendan Dolan-Gavitt

  I'm looking for an implementation of regular expression matching that operates on a stream of data -- i.e., it has an API that allows a user to pass in one character at a time and report when a match is found on the stream of characters seen so far. Only very basic (classic) regular expressions are needed, so a DFA/NFA based implementation seems like it would be well-suited to the problem. Based on the fact that it's possible to do regular expression matching using a DFA/NFA in a single linear sweep, it seems like a streaming implementation should be possible. Requirements: The library should try to wait until the full string has been read before performing the match. The data I have really is streaming; there is no way to know how much data will arrive, it's not possible to seek forward or backward. Implementing specific stream matching for a couple special cases is not an option, as I don't know in advance what patterns a user might want to look for. For the curious, my use case is the following: I have a system which intercepts memory writes inside a full system emulator, and I would like to have a way to identify memory writes that match a regular expression (e.g., one could use this to find the point in the system where a URL is written to memory). I have found (links de-linkified because I don't have enough reputation): stackoverflow.com/questions/1962220/apply-a-regex-on-stream stackoverflow.com/questions/716927/applying-a-regular-expression-to-a-java-i-o-stream www.codeguru.com/csharp/csharp/cs_data/searching/article.php/c14689/Building-a-Regular-Expression-Stream-Search-with-the-NET-Framework.htm But all of these attempt to convert the stream to a string first and then use a stock regular expression library. Another thought I had was to modify the RE2 library, but according to the author it is architected around the assumption that the entire string is in memory at the same time. If nothing's available, then I can start down the unhappy path of reinventing this wheel to fit my own needs, but I'd really rather not if I can avoid it. Any help would be greatly appreciated!

• C++ struct, public data members and inheritance

  - by Marius

  Is it ok to have public data members in a C++ class/struct in certain particular situations? How would that go along with inheritance? I've read opinions on the matter, some stated already here http://stackoverflow.com/questions/952907/practices-on-when-to-implement-accessors-on-private-member-variables-rather-than http://stackoverflow.com/questions/670958/accessors-vs-public-members or in books/articles (Stroustrup, Meyers) but I'm still a little bit in the shade. I have some configuration blocks that I read from a file (integers, bools, floats) and I need to place them into a structure for later use. I don't want to expose these externally just use them inside another class (I actually do want to pass these config parameters to another class but don't want to expose them through a public API). The fact is that I have many such config parameters (15 or so) and writing getters and setters seems an unnecessary overhead. Also I have more than one configuration block and these are sharing some of the parameters. Making a struct with all the data members public and then subclassing does not feel right. What's the best way to tackle that situation? Does making a big struct to cover all parameters provide an acceptable compromise (I would have to leave some of these set to their default values for blocks that do not use them)?

• Define "Validation in the Model"

  - by sunwukung

  There have been a couple of discussions regarding the location of user input validation: http://stackoverflow.com/questions/659950/should-validation-be-done-in-form-objects-or-the-model http://stackoverflow.com/questions/134388/where-do-you-do-your-validation-model-controller-or-view These discussions were quite old, so I wanted to ask the question again to see if anyone had any fresh input. If not, I apologise in advance. If you come from the Validation in the Model camp - does Model mean OOP representation of data (i.e. Active Record/Data Mapper) as "Entity" (to borrow the DDD terminology) - in which case you would, I assume, want all Model classes to inherit common validation constraints. Or can these rules simply be part of a Service in the Model - i.e. a Validation service? For example, could you consider Zend_Form and it's validation classes part of the Model? The concept of a Domain Model does not appear to be limited to Entities, and so validation may not necessarily need to be confined to this Entities. It seems that you would require a lot of potentially superfluous handing of values and responses back and forth between forms and "Entities" - and in some instances you may not persist the data recieved from user input, or recieve it from user input at all.

• How to use Transaction in Entity FrameWork?

  - by programmerist

  How to use Transaction in Entity FrameWork? i read some links on Stackoverflow : http://stackoverflow.com/questions/815586/entity-framework-using-transactions-or-savechangesfalse-and-acceptallchanges BUT; i have 3 table so i have 3 entities: CREATE TABLE Personel (PersonelID integer PRIMARY KEY identity not null, Ad varchar(30), Soyad varchar(30), Meslek varchar(100), DogumTarihi datetime, DogumYeri nvarchar(100), PirimToplami float); Go create TABLE Prim (PrimID integer PRIMARY KEY identity not null, PersonelID integer Foreign KEY references Personel(PersonelID), SatisTutari int, Prim float, SatisTarihi Datetime); Go CREATE TABLE Finans (ID integer PRIMARY KEY identity not null, Tutar float); Personel, Prim,Finans my tables. if you look Prim table you can see Prim value float value if i write a textbox not float value my transaction must run. using (TestEntities testCtx = new TestEntities()) { using (TransactionScope scope = new TransactionScope()) { // do someyihng... testCtx.Personel.SaveChanges(); // do someyihng... testCtx.Prim.SaveChanges(); // do someyihng... testCtx.Finans.SaveChanges(); scope .Complete(); success = true; } } How can i do that?

• Using Cucumber or RSpec+Selenium to create end user documentation?

  - by carolclarinet

  Has anyone tried creating end user (potentially online, potentially to be printed) help/documentation out of your cucumber scenarios? Or taken screenshots for use in documentation using RSpec and Selenium RC's ability to do so? For Cucumber, I'm imagining something like: Scenario: If you want to add a link Given I am on the edit blog post page When I press the "add link" button And I type in a link URL "http://stackoverflow.com" And I click "OK" Then the blog post should have 1 link Translating to the documentation: If you want to add a link, go to the edit blog post page. Press the "add link" button and type a URL, like "http://stackoverflow.com", into the link URL field. Click "OK". Would it be worth my time to try and, for one, write something to parse my Cucumber features into documentation, and two, to write/structure my Cucumber features in such a way as to create good documentation? Would the resulting documentation end up sounding really boring without much variation in the structure? Is there anything else out there like this idea? Doxygen looks like it's more for code documentation than end-user documentation. What about automatically taking screenshots? This seems like a more fruitful path-- just reuse the code that takes a screenshot when an RSpec test fails and have it take one in prescribed situations. Is there a better way to do this?

• IIS6 throws error for jquery.

• Setting Icon for wpf application (VS 08)

  - by baron

  Hi everyone, Before going much further i'll mention I have tried solutions in following: http://stackoverflow.com/questions/320677/how-do-i-set-the-icon-for-my-application-in-visual-studio-2008 http://stackoverflow.com/questions/198848/set-application-icon-from-resources-in-vs-05 I am trying to set an icon for my application. AFAIK, I need potentially 3 images? 1 image is the actual image in explorer when clicking on the .exe (thumbnail for the exe) 1 image (tiny) in the top left corner (16 x 16? Not entirely sure) 1 image in the start menu dock, to the left of the app (maybe 32x32? again not sure) So thats fine. Now I have selected an Icon. How do I use it in one of above situations? I have tried adding it in resources, nothing seems to happen. Following that first SO solution, "First go to Resource View (from menu: View -- Other Window -- Resource View). Then in Resource View navigate through resources, if any. If there is already a resource of Icon type, added by Visual Studio, then open and edit it. Otherwise right-click and select Add Resource, and then add a new icon." The resource view is empty, and I cannot right click in this view. If I right click on the solution properties resources I can add the icon image, but it doesn't show in either of the locations listed above. (or anywhere that I can see) What am I doing wrong?

• Laravel4: Checking many-to-many relationship attribute even when it does not exist

  - by Simo A.

  This is my first time with Laravel and also Stackoverflow... I am developing a simple course management system. The main objects are User and Course, with a many-to-many relationship between them. The pivot table has an additional attribute, participant_role, which defines whether the user is a student or an instructor within that particular course. class Course extends Eloquent { public function users() { return $this->belongsToMany('User')->withPivot('participant_role')->withTimestamps(); } } However, there is an additional role, system admin, which can be defined on the User object. And this brings me mucho headache. In my blade view I have the following: @if ($course->pivot->participant_role == 'instructor') { // do something here... } This works fine when the user has been assigned to that particular $course and there is an entry for this user-course combination in the pivot table. However, the problem is the system administrator, who also should be able to access course details. The if-clause above gives Trying to get property of non-object error, apparently because there is no entry in the pivot table for system administrator (as the role is defined within the User object). I could probably solve the problem by using some off-the-shelf bundle for handling role-based permissions. Or I could (but don't want to) do something like this with two internal if-clauses: if (!empty($course->pivot)) { if ($course->pivot->participant_role == 'instructor') { // do something... } } Other options (suggested in partially similar entries in Stackoverflow) would include 1) reading all the pivot table entries to an array, and use in_array to check if a role exists, or even 2) SQL left join to do this on database level. However, ultimately I am looking for a compact one-line solution? Can I do anything similar to this, which unfortunately does not seem to work? if (! empty ($course->pivot->participant_role == 'instructor') ) { // do something... } The shorter the answer, the better :-). Thanks a lot!

• AWS Cloud Formation.Requires capabilities : [CAPABILITY_IAM] (Child Stack)

  - by Drew Khoury

  I'm running a CloudFormation template in the AWS Console. Running Stack Directly I started with a template that used IAM resources, and the console prompts me to acknowledge IAM capabilities when running the stack directly. Running Stack as a child I then tried to call the same stack from a parent stack and did not receive the same prompt. The stack then failed with the message: Requires capabilities : [CAPABILITY_IAM] Research The docs indicate that I can run CF scripts in a number of ways. There's plenty of docs around CLI/API and supplying the capability parameter, but there appears to be no information about how to make sure it's applied when running through the console. http://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/using-iam-template.html IAM Resources in AWS CloudFormation Templates CF Console CLI API What I've done / What I think I've raised an issue via the forum for now, but no response (yet): https://forums.aws.amazon.com/thread.jspa?threadID=139160 I suspect this is a bug in the Console, as there doesn't appear to be any documentation of how to change the behaviour via the console and as far as I'm aware this should just work. Anyone came across the same problem, or can report that it's working fine for them?

On another machine, which is accidentally a windows server 2003, it returns almost immediately with the correct domain controller name inside the returned DOMAIN_CONTROLLER_INFO structure. Now the question is what is missing on my workstation for that API to find the correct domain controller?

• Prohibit installers from modifying Windows Firewall rules

  - by Sysadmin

  Some application installers tamper with the Windows Firewall rules. I would like to prohibit such automated modifications of the Windows Firewall rules on Windows 7 machines (which use the Windows 7 version of Windows Firewall). Is there some setting that would accomplish this, or would it be necessary to resort to hooking the Windows Firewall API? I would like to prevent these modifications from being made at all, rather than backing up the firewall rules before the installation and restoring them afterward. A TechNet article indicates that there is no way to prevent installers from accessing the Windows Firewall API, but that article pertains to the Windows XP version of Windows Firewall. The Windows 7 version of Windows Firewall is newer and much-improved over the Windows XP incarnation, so it is unclear whether that advice is still pertinent. A similar SuperUser question had received a couple of responses, but neither response answered the question, likely because they misunderstood that question due to the way it was worded. I hope that I have explained this problem clearly. Don't hesitate to ask if you need any clarification.

• Network connection to Firebird 2.1 became slow after upgrading to Ubuntu 10.04

  - by lyle

  We've got a setup that we're using for different clients : a program connecting to a Firebird server on a local network. So far we mostly used 32bit processors running Ubuntu LTS (recently upgraded to 10.04). Now we introduced servers running on 64bit processors, running Ubuntu 10.04 64bit. Suddenly some queries run slower than they used to. In short: running the query locally works fine on both 64bit and 32bit servers, but when running the same queries over the network the 64bit server is suddenly much slower. We did a few checks with both local and remote connections to both 64bit and 32bit servers, using identical databases and identical queries, running in Flamerobin. Running the query locally takes a negligible amount of time: 0.008s on the 64bit server, 0.014s on the 32bit servers. So the servers themselves are running fine. Running the queries over the network, the 64bit server suddenly needs up to 0.160s to respond, while the 32bit server responds in 0.055s. So the older servers are twice as fast over the network, in spite of the newer servers being twice as fast if run locally. Apart from that the setup is identical. All servers are running the same installation of Ubuntu 10.04, same version of Firebird and so on, the only difference is that some are 64 and some 32bit. Any idea?? I tried to google it, but I couldn't find any complains that Firebird 64bit is slower than Firebird 32bit, except that the Firebird 2.1 change log mentions that there's a new network API which is twice as fast, as soon as the drivers are updated to use it. So I could imagine that the 64bit driver is still using the old API, but that's a bit of a stretch, I guess. Thanx in advance for any replies! :)

• Windows 2008 server smart card security module problem

  - by chris13work

  Hi, I've got a smart card reader and a server application using it as a security module. If I run it under DOS prompt, everything is fine. The server is running and clients can connect to it. I tried to install the server as window service and start it. The server starts but always gives back authentication error because it cannot call the smart card to do encryption. Then I tried to start it with task scheduler and set the trigger factor as "on startup". The server starts also but still cannot access the smart card reader. Then I tried remote desktop to the machine and run the server application under DOS prompt. Same error is returned. The situation is that the smart card reader only works under active console desktop environment. In the server application, WINSCARD API is used to access the smart card reader. Any suggestion so that we can access the smart card reader in running services? OS: Windows Server 2008 Smart Card Driver: Windows USB smart card Reader Smart Card API: WINSCARD

• Are there any Graphical PowerShell tools?

  - by Dai

  As a developer for the .NET platform, I like to "explore" a platform, framework or API by browsing through the API documentation which explains what everything is - everything is covered and when I use tools like Reflector or Object Browser then I get to know for certain what I'm working with. When I'm writing my own software I can use tools like the Object Test Bench to explore and work with my classes directly. I'm looking for something similar, but for PowerShell - and ones that avoid text-mode. PowerShell is nice, and there are a lot of cool "discoverability"-things it has, such as the "Verb-Noun" syntax, however when I'm working with Exchange Server, for example, I wanted to get a list of AD Permissions on a Receive Connector and I got this list: [PS] C:\Windows\system32>Get-ADPermission "Client SVR6" -User "NT AUTHORITY\Authenticated Users" | fl User : NT AUTHORITY\Authenticated Users Identity : SVR6\Client SVR6 Deny : False AccessRights : {ExtendedRight} IsInherited : False Properties : ChildObjectTypes : InheritedObjectType : InheritanceType : All User : NT AUTHORITY\Authenticated Users Identity : SVR6\Client SVR6 Deny : False AccessRights : {ExtendedRight} IsInherited : False Properties : ChildObjectTypes : InheritedObjectType : InheritanceType : All User : NT AUTHORITY\Authenticated Users Identity : SVR6\Client SVR6 Deny : False AccessRights : {ExtendedRight} IsInherited : False Properties : ChildObjectTypes : InheritedObjectType : InheritanceType : All User : NT AUTHORITY\Authenticated Users Identity : SVR6\Client SVR6 Deny : False AccessRights : {ExtendedRight} IsInherited : False Properties : ChildObjectTypes : InheritedObjectType : InheritanceType : All User : NT AUTHORITY\Authenticated Users Identity : SVR6\Client SVR6 Deny : False AccessRights : {ExtendedRight} IsInherited : False Properties : ChildObjectTypes : InheritedObjectType : InheritanceType : All User : NT AUTHORITY\Authenticated Users Identity : SVR6\Client SVR6 Deny : True AccessRights : {ReadProperty} IsInherited : True Properties : {ms-Exch-Availability-User-Password} ChildObjectTypes : InheritedObjectType : ms-Exch-Availability-Address-Space InheritanceType : Descendents [PS] C:\Windows\system32> Note how the first few entries contain identical text - there's no way to tell them apart easily. But if there was a GUI presumably it would let me drill-down into the differences better. Are there any tools that do this?

• apache segmentation error

  - by lush

  I can't start Apache with the following errors: [root@web]# /etc/init.d/httpd start Starting httpd: /bin/bash: line 1: 19232 Segmentation fault /usr/sbin/httpd [root@web]# /usr/sbin/apachectl -k start /usr/sbin/apachectl: line 102: 19919 Segmentation fault $HTTPD $OPTIONS $ARGV I use webmin control panel and I've already tried re-installing Apache from scratch. Can someone advise what else I should try to do? Many thanks. UPDATE: The only line is always written in the error logs which seems not to be very important: [Mon Nov 14 19:00:09 2011] [notice] suEXEC mechanism enabled (wrapper: /usr/sbin/suexec) UPDATE 2: I've recently had the error below in the logs. Looks like some modules are incompatible, so I've just disabled these extensions: fileinfo and mcrypt in my php.ini. I should be able to start the web server without them. PHP Warning: PHP Startup: fileinfo: Unable to initialize module\nModule compiled with module API=20050922, debug=0, thread-safety=0\nPHP compiled with module API=20060613, debug=0, thread-safety=0\nThese options need to match\n in Unknown on line 0 PHP Warning: Module 'mcrypt' already loaded in Unknown on line 0 UPDATE 3: [root@web]# file /usr/sbin/httpd /usr/sbin/httpd: ELF 64-bit LSB shared object, AMD x86-64, version 1 (SYSV), for GNU/Linux 2.6.9, stripped [root@web]# uname -m x86_64
