  • UIView transparency shows how the sausages are made!

    - by quixoto
    I have a UIView container that has two UIImageViews inside it, one partially obscuring the other (they're being composed like this to allow for occasional animation of one "layer" or another. Sometimes I want to make this container 50% alpha, so what the users sees fades. Here's the problem: setting my container view to 50% alpha makes all my subviews inherit this as well, and now you can see through the first subview into the second, which in my application has a weird X-Ray effect that I'm not looking for. What I'm after, of course, is for what the user currently sees to become 50% transparent-- the equivalent of flattening the visible view into one bitmap, and then making that 50% alpha. What are my best bets for accomplishing this? Ideally would like to avoid actually, dynamically flattening the views if I can help it, but best practices on that welcome as well. Am I missing something obvious? Since most views have subviews and would run into this issue, I feel like there's some obvious solution here. Thanks!

  • MySQL LOAD DATA LOCAL INFILE example in python?

    - by David Perron
    I am looking for a syntax definition, example, sample code, wiki, etc. for executing a LOAD DATA LOCAL INFILE command from python. I believe I can use mysqlimport as well if that is available, so any feedback (and code snippet) on which is the better route, is welcome. A Google search is not turning up much in the way of current info The goal in either case is the same: Automate loading hundreds of files with a known naming convention & date structure, into a single MySQL table.

  • remove ViewController from memory

    - by user262325
    hello everyone I hope to load an ViewController and do something then unload it from memory. if (self.vViewController5.view.superview==nil) { ViewController5 *blueController = [[ViewController5 alloc] initWithNibName:@"View5" bundle:nil]; self.vViewController5 = blueController; [self.vViewController5 setDelegate:self]; [blueController release]; } [self presentModalViewController:vViewController5 animated:YES]; later, call [self dismissModalViewControllerAnimated:YES]; but I found that dismissModalViewControllerAnimated does not trigger the event viewDidUnload of Viewcontroller5. I try function release but it caused program collapse. I also try removeFromSuperView but it does not trigger the event ViewDidUnload neither. Welcome any comment Thanks interdev

  • How can I make a career in Formal Methods programming in USA?

    - by A5al Andy
    I've found that my (USA) professors recoil with a near-disgust when I ask them about how to pursue a career in Formal Methods programming. They say, "Oh, that stuff! That stuff is anal. You don't need that European POS to get a job." I'm sure I'll get a job without it, but Formal Methods interests me so much that I bet I'd like to make a career of it. I'd like to learn about Formal Methods at an American University and then work in that field here. I've found that even professors at more important universities than mine don't seem to welcome Formal Methods. Almost all FM research project webpages are semi-abandoned and moldering. Europe is where the action seems to be for this. Can anyone suggest a plan of attack, and along the way explain the antipathy to Formal Methods in the US? I'm a sophomore at a public university in the South.

  • Customizing RadioSelect

    - by Kugel
    Hello I have a form with ChoiceField whose widget is set to RadioSelect Now to override default html output one needs to subclass RadioFieldRenderer like this: class SimpleRadioFieldRenderer(forms.widgets.RadioFieldRenderer): def render(self): """Outputs widget without <ul> or <li> tags.""" return mark_safe(u'\n'.join([u'%s' % force_unicode(w.tag()) for w in self])) All is good now except I'd like to be able to render 1 radio button at a time from template. Something like this: {{ form.myfield.0 }}} Or perhaps hanging it onto widget itself: {{ form.myfield.field.widget.0 }} What bugs me is that RadioFieldRenderer already implements __get_item__ to get just one RadioInput. The problem is that the renderer does not contain data, neither does the widget. And I'd really hate to mess with Field and BoundField. I need this to inject html before/after each radiobutton and I'd like it to be done in the template. From the code it would be easy. Any ideas are welcome.

  • Approaches for memcached sessions

    - by Industrial
    Hi everybody, I was thinking about using memcached to store sessions instead of mySQL, which seemed like a good idea, at first. When it comes to the failover part of utilizing memcached servers, It's a bit worrying that my sessions will stop working if the memcached would go offline. It will certainly affect my users. There's a few techniques that we already utilize to reduce failover, including having a pool of servers available to compensate in the event of downtime, utilizing sharding/consistent hashing across the server pool and so on. We would also do some sort of graceful degradation that tells the users that something have gone wrong and they are welcome to login again, in the event of them being kicked out due to memcached server failover. So how does people generally deal with these issues when storing sessions on memcached servers?

  • Can you let users upload Sinatra apps and run them inside Rails as middleware?

    - by Brian Armstrong
    I want to let users write small custom apps (think themes or plugins on Wordpress) and upload/run them on my site. I'm thinking about using Sinatra apps for this since it would give the users a lot of flexibility, and then running them as middleware inside my rails app. But I can't figure out the security implications of this. I tried creating a simple sinatra app as middleware, and it has access to all the rails models and everything - so that is bad. Is there a way for rack to keep these separate so that the sinatra apps are effectively sandboxed and can't do any bad things (outside of an API or some specific way I setup for them to communicate)? There may be an easier way to accomplish this that I haven't thought of too, so ideas welcome. Thanks!

  • Rails: Polymorphic User Table a good idea with AuthLogic?

    - by sscirrus
    Hi everyone, I have a system where I need to login three user types: customers, companies, and vendors from one login form on the home page. I have created one User table that works according to AuthLogic's example app at http://github.com/binarylogic/authlogic_example. I have added a field called "User Type" that currently contains either 'Customer', 'Company', or 'Vendor'. Note: each user type contains many disparate fields so I'm not sure if Single Table Inheritance is the best way to go (would welcome corrections if this conclusion is invalid). Is this a polymorphic association where each of the three types is 'tagged' with a User record? How should my models look so I have the right relationships between my User table and my user types Customer, Company, Vendor? Thanks very much!

  • Getting a summary of comments in Jira

    - by Ross Alexander
    I currently maintain a Jira system at work and I have been tasked with a rather strange request which is too find a way of 'making a summary of a comment'. In the ideal situation this would allow a user to write a comment and a quick summary however I doubt this is something available in Jira / something that is feasible. Alternatively a summary of all comments would be nice that will allow our technical writers a way to clarify fixes through the information in the comments. If any one out there has ANY suggestions or ideas on this they are most welcome :) Sorry if this question is slightly general but I cannot find any thing that remotely helps on google, wondering if any Jira experts can push me in the right direction. Thanks

  • Find all words containing characters in UNIX

    - by fahdshariff
    Given a word W, I want to find all words containing the letters in W from /usr/dict/words. For example, "bat" should return "bat" and "tab" (but not "table"). Here is one solution which involves sorting the input word and matching: word=$1 sortedWord=`echo $word | grep -o . | sort | tr -d '\n'` while read line do sortedLine=`echo $line | grep -o . | sort | tr -d '\n'` if [ "$sortedWord" == "$sortedLine" ] then echo $line fi done < /usr/dict/words Is there a better way? I'd prefer using basic commands (instead of perl/awk etc), but all solutions are welcome! To clarify, I want to find all permutations of the original word. Addition or deletion of characters is not allowed.

  • [jquery/javascript] Trigger function when mouse click inside textarea AND type stop typing...

    - by marc
    Welcome, In short, my website use BBcode system, and i want allow users to preview message without posting it. I'm using JQuery library. I need 3 actions. 1) When user click in textarea i want display DIV what will contain preview, i want animate opening. 2) When user typing, i want dynamical load parsed by PHP code to DIV. (i'm still thinking what will be best option... refresh every 2 seconds, or maybe we can detect and refresh after 1 second of inactivity [stop typing]) 3) When user click outside textarea i want close preview div with animation. For example the PHP parser will have patch /api/parser.php and variable by POST called $_POST['message']. Any idea my digital friends ?

  • Usability: call for action

    - by Shyam
    I am designing a page, with tiny portlets. Now, I personally like my actions on the right side, yet I wonder if there are methodologies that are targeted about usability. After all, most applications are aimed at the user. What about yourself? Do you prefer information to be on top, on the left or on the right? I've you need to take some sort of action, do you prefer buttons on the left? References to good books and webpages are very welcome!

  • Best language to learn complementing java

    - by danielrutledge
    Hi all, I'm a somewhat experienced java ee developer, and I wish to complement my background by learning a newish language. I'm recently out of school where I did a ton of scientific computing and some functional programming, so I'm pretty comfortable with those families of languages. If at all possible, I'd like to pick a language with some market value, though I know this is tough to gauge. After snooping around a bit, the consensus seems to be one of Python/Ruby/Perl; how would each of these work with java in a web application environment, and in your opinion which complements it best? Any other suggestions for languages would also be welcome.

  • What is the most you've charged for a single programming job?

    - by David Murdoch
    This question/wiki is more aimed at my fellow freelancers rather than companies or groups...but any and all feedback definitely is welcome. When quoting jobs for anything over $10,000 I always feel uneasy and unsure about the estimate I'm providing (though, I'm not sure why, I know what I'm worth [ I think :-) ] and I charge appropriately. I'm sure there are more (noob) freelancers here on S.O. that feel the same way. In danger of being voted closed because of its subjective (but factual) nature - the question(s): What is the largest amount you have charged for a single programming job (not including maintenance, support, or residual income). What are some of the details of the specific job? (research, q&a, challenges, etc) What languages did you use to get the job done? Assuming you bill your work at an hourly rate, what was the rate? How long did the job actually take you to complete? (from start to deployment, how many weeks, months, years?)

  • Java, searching through folders to match a name

    - by Nick
    Hi folks, I using java to search for a file or folder that matches a specific case. For instance i want to search through all the files and folders and iterate through them as many times as necessary untill i find a result. The catch I searching for files and folders through a binary image of a file system. This means i doubt there are any preexisting classes such java.file.* to do it for me. If it helps i can tell you that i can tell the difference between files and folders easily enough. (a folder is flagged as 0x20) The only way i can think of is to do a standard loop and iterated several times but this limits me if a file or folder is several folders deep. All input greatly welcome

  • Does there exist an "idea checkout system" on the Internet?

    - by TimeSpace Traveller
    Greetings. I would like to ask the following question: is there anything on the Internet like an "idea checkout" system? Situation: I'm a software developer. Since my current job has started 2 years ago, my mentor at that time has pointed me to the open source world. I have only put little time to look at some of the open source projects, let alone any contribution. However, it is my wish to start developing something outside of the work. Well, except a little problem. I don't know what to develop! It is not about the technical knowledge; the problem is that, I am not a creative person. I am very good at analytical thinking, as well as debugging skills. When being told by my work partners to develop a solution, I could get it done without a problem. However, outside of work, I have no idea what to develop. When I look at the Internet, it seems that so many people have already been developing on so many interesting stuff, making me wonder what I could develop, so that I would not reinvent something already existed. That starts to make me wonder. On the Internet, is there anything like an "idea checkout" system or society? For example, some people would throw in as a software idea, and the system would keep it as an "inventory"; later, a potential software developer would "check out" the idea, just a how people would check out a book from the library. Then, the developer would check the "idea" back in, with a certain kind of work-in-progress or developed software, thus becoming an open-source project. I have just noticed that here at stackoverflow, there is a "Project-Ideas" tag, so perhaps that can provide me some ideas on what to develop; still, my wonder is about a system that people would provide ideas, and people would check out ideas to develop / implement into actual solution. Is there such a system or society existing anywhere on the Internet? Any input is welcome! Thank you very much. Update: Thank you for everyone who has answered my question. Certainly, "getting idea" is part of my problem; as a software developer, however, I'm concerned more than just "getting idea". What I am concerned more, as I have commented, is about the existence of such an idea exchanging ecosystem, capable to initiate open-source projects. I'll put an example here. Say, person A has an idea of music search program, but not search by the attributes of the music (composer, singer, publisher, lyrics, etc.); instead, he wants a program (and a database) to search a piece of music by melody. Very often, people only remember a piece of music by its melody, not even the name of the music (e.g. the music he wants was only once heard in a bookstore, but the melody just gets stuck in his head!). In order to find that piece, normally he would just need to blindly search for it, and spent a long time to do so. A search by melody would enable person A to find the piece much quicker. However, he would not want to personally work on it, not just because of the complexity (he is not a musician and/or programmer, knowing almost nothing about music systems in computer, search algorithms, etc.), but also legal issues (RIAA??), thus he would just like to keep the idea at some place, and let other people to work on that. Now, a developer (person B) may be at the same stage as I am right now, wishing to find something to develop, but not having an idea. With the idea exchanging ecosystem, person B will search, and somehow discover person A's music search idea, and feeling interested enough to work on it. So he "checks out" the idea, start working on it (at least a skeleton), and checks back in with the progress. An open-source project starts from here, fulfilling person A's wish, and person B's programming desire. The above is just an example, because there are already such systems exist on the Internet, but it illustrates what I think about the idea exchange system in my mind. My main concern is about idea exchanging ecosystem, not at personal and unorganized level, but at a semi-organized protocol that's specifically for software developers, having actual projects coming out as the fruits. Not about "projects", but about "ideas and product of ideas". Hopefully that would clear up some of the original idea of this question. Any input is welcome; in fact, I would like to hear as many people as possible how everyone thinks about this. Thank you very much!

  • how to read specific number of floats from file in python?

    - by sahel
    I am reading a text file from the web. The file starts with some header lines containing the number of data points, followed the actual vertices (3 coordinates each). The file looks like: # comment HEADER TEXT POINTS 6 float 1.1 2.2 3.3 4.4 5.5 6.6 7.7 8.8 9.9 1.1 2.2 3.3 4.4 5.5 6.6 7.7 8.8 9.9 POLYGONS the line starting with the word POINTS contains the number of vertices (in this case we have 3 vertices per line, but that could change) This is how I am reading it right now: ur=urlopen("http://.../file.dat") j=0 contents = [] while 1: line = ur.readline() if not line: break else: line=line.lower() if 'points' in line : myline=line.strip() word=myline.split() node_number=int(word[1]) node_type=word[2] while 'polygons' not in line : line = ur.readline() line=line.lower() myline=line.split() i=0 while(i<len(myline)): contents[j]=float(myline[i]) i=i+1 j=j+1 How can I read a specified number of floats instead of reading line by line as strings and converting to floating numbers? Instead of ur.readline() I want to read the specified number of elements in the file Any suggestion is welcome..

  • Fast partial sorting algorithm

    - by trican
    I'm looking for a fast way to do a partial sort of 81 numbers - Ideally I'm looking to extract the lowest 16 values (its not necessary for the 16 to be in the absolutely correct order). The target for this is dedicated hardware in an FPGA - so this slightly complicated matters as I want the area of the resultant implementation as small as possible. I looked at and implemented the odd-even merge sort algorithm, but I'm ideally looking for anything that might be more efficient for my needs (trade algorithm implementation size for a partial sort giving lowest 16, not necessarily in order as opposed to a full sort) Any suggestions would be very welcome Many thanks

  • Share pre-initialized GIT repository

    - by Theo.T
    We were sharing a GIT repository via file-sharing system (smb://) and got it badly corrupted (a power cut meanwhile the post-send :P). Being new to GIT, trying to fix it I made it even worse and I lost all the refs (left with the object folder). Since the incident I haven't had the time to look at the problem and have just been keeping committing to my local clone. So my question is : Is there a way to copy the local repository back to the location of the old repository and make it a shared repository in order to keep some track of previous the history ? That's all I could figure out (I'm still a git-noob), any other solutions are more than welcome ! Thanks in advance !

  • Start PyGTK cellrenderer edit from code

    - by mkotechno
    I have a treeview with an editable CellRendererText: self.renderer = gtk.CellRendererText() self.renderer.set_property('editable', True) But now I need to launch the edition from code instead from user, this is to focus the user attention in the fact he just created a new row and needs to be named. I tried this but does not work: self.renderer.start_editing( gtk.gdk.Event(gtk.gdk.NOTHING), self.treeview, str(index), gtk.gdk.Rectangle(), gtk.gdk.Rectangle(), 0) Neither does not throw errors, but the documentation about for what is each argument is not clear, in fact I really don't know if start_editing method is for this. All suggestions are welcome, thanks.

  • Enforcing a query in MySql to use a specific index

    - by Hossein
    Hi, I have large table. consisting of only 3 columns (id(INT),bookmarkID(INT),tagID(INT)).I have two BTREE indexes one for each bookmarkID and tagID columns.This table has about 21 Million records. I am trying to run this query: SELECT bookmarkID,COUNT(bookmarkID) AS count FROM bookmark_tag_map GROUP BY tagID,bookmarkID HAVING tagID IN (-----"tagIDList"-----) AND count >= N which takes ages to return the results.I read somewhere that if make an index in which it has tagID,bookmarkID together, i will get a much faster result. I created the index after some time. Tried the query again, but it seems that this query is not using the new index that I have made.I ran EXPLAIN and saw that it is actually true. My question now is that how I can enforce a query to use a specific index? also comments on other ways to make the query faster are welcome. Thanks
