• Passing arguments to a python service

  - by Grim

  Hi, I need some help with a python service. I have a service written in Python. What I need to do is to pass it some arguments. Let me give you an example to explain it a bit better. Lets say I have a service, that does nothing but writes something to a log. I'd like to write the same thing into the log several times, so I use a loop. I would like to pass the counter for the loop when I start the service, but I have no idea how. I start the service with: win32serviceutil.HandleCommandLine(WinService) I'm looking for something like win32serviceutil.HandleCommandLine(WinService,10) I don't really care how its done, as long as I can pass arguments to it. Have been trying to get this to work for the better part of the day with no luck. Also, the service isn't run directly, but is imported and then run from there.

• Major inconsistencies in Zend Framework

  - by John Nall

  Okay first of all let me just say Zend Framework is the greatest tool I have ever used in 30+ years of programming (well, for web development, Qt wins the desktop market). However, through my use I have noticed some glaring and annoying inconsistencies. For instance, Zend_Form_Element's have a setAttrib() method. Now why the hell is this the only method in that API which is abbrev.? Why then am I using setRequired() instead of setReq()? I have more examples, I am extremely nerd raged about this. It is completely ruining what could have been God's gift to web development. FOR FUTURE REFERENCE NEVER ABBREV. THINGS WHEN MAKING AN API. also always filter data before storing it i m o Who do we talk to about this, where something will actually get done about it?

• Static assembly initialization

  - by ph0enix

  I'm attempting to develop an Interceptor framework (in C#) where I can simply implement some interfaces, and through the use of some static initialization, register all my Interceptors with a common Dispatcher to be invoked at a later time. The problem lies in the fact that my Interceptor implementations are never actually referenced by my application so the static constructors never get called, and as a result, the Interceptors are never registered. If possible, I would like to keep all references to my Interceptor libraries out of my application, as this is my way of (hopefully) enforcing loose coupling across different modules. Hopefully this makes some sense. Let me know if there's anything I can clarify... Does anyone have any ideas, or perhaps a better way to go about implementing my Interceptor pattern? TIA, Jeremy

• What advantage does Monad give us over an Applicative?

  - by arrowdodger

  I've read this article, but didn't understand last section. The author says that Monad gives us context sensitivity, but it's possible to achieve the same result using only an Applicative instance: let maybeAge = (\futureYear birthYear -> if futureYear < birthYear then yearDiff birthYear futureYear else yearDiff futureYear birthYear) <$> (readMay futureYearString) <*> (readMay birthYearString) It's uglier for sure, but beside that I don't see why we need Monad. Can anyone clear this up for me?

• How to join by column name

  - by Daniel Vaca

  I have a table T1 such that gsdv |nsdv |esdv ------------------- 228.90 |216.41|0.00 and a table T2 such that ds |nm -------------------------- 'Non-Revenue Sales'|'ESDV' 'Gross Sales' |'GSDV' 'Net Sales' |'NSDV' How do I get the following table? ds |nm |val --------------------------------- 'Non-Revenue Sales'|'ESDV'|0.00 'Gross Sales' |'GSDV'|228.90 'Net Sales' |'NSDV'|216.41 I know that I can this by doing the following SELECT ds,nm,esdv val FROM T1,T2 WHERE nm = 'esdv' UNION SELECT ds,nm,gsdv val FROM T1,T2 WHERE nm = 'gsdv' UNION SELECT ds,nm,nsdv val FROM T1,T2 WHERE nm = 'nsdv' but I am looking for a more generic/nicer solution. I am using Sybase, but if you can think of a way to do this with other DBMS, please let me know. Thanks.

• How to speed up saving a UIImagePickerController image from the camera to the filesystem via UIImagePNGRepresentation()?

  - by kazuhito0000

  I'm making an applications that let users take a photo and show them both in thumbnail and photo viewer. I have NSManagedObject class called photo and photo has a method that takes UIImage and converts it to PNG using UIImagePNGRepresentation() and saves it to filesystem. After this operation, resize the image to thumbnail size and save it. The problem here is UIImagePNGRepresentation() and conversion of image size seems to be really slow and I don't know if this is a right way to do it. Tell me if anyone know the best way to accomplish what I want to do. Thank you in advance.

• Intersection between sets containing different types of variables

  - by Gacek

  Let's assume we have two collections: List<double> values List<SomePoint> points where SomePoint is a type containing three coordinates of the point: SomePoint { double X; double Y; double Z; } Now, I would like to perform the intersection between these two collections to find out for which points in points the z coordinate is eqal to one of the elements of values I created something like that: HashSet<double> hash = new HashSet<double>(points.Select(p=>p.Z)); hash.IntersectWith(values); var result = new List<SomePoints>(); foreach(var h in hash) result.Add(points.Find(p => p.Z == h)); But it won't return these points for which there is the same Z value, but different X and Y. Is there any better way to do it?

• Using Rails, how can I set my primary key to not be an integer-typed column?

  - by Rudd Zwolinski

  I'm using Rails migrations to manage a database schema, and I'm creating a simple table where I'd like to use a non-integer value as the primary key (in particular, a string). To abstract away from my problem, let's say there's a table employees where employees are identified by an alphanumeric string, e.g. "134SNW". I've tried creating the table in a migration like this: create_table :employees, {:primary_key => :emp_id} do |t| t.string :emp_id t.string :first_name t.string :last_name end What this gives me is what seems like it completely ignored the line t.string :emp_id and went ahead and made it an integer column. Is there some other way to have rails generate the PRIMARY_KEY constraint (I'm using PostgreSQL) for me, without having to write the SQL in an execute call? NOTE: I know it's not best to use string columns as primary keys, so please no answers just saying to add an integer primary key. I may add one anyway, but this question is still valid.

• What is the role of `while`-loops in computation expressions in F#?

  - by MizardX

  If you define a While method of the builder-object, you can use while-loops in your computation expressions. The signature of the While method is: member b.While (predicate:unit->bool, body:M<'a>) : M<'a> For comparison, the signature of the For method is: member b.For (items:seq<'a>, body:unit->M<'a>) : M<'a> You should notice that, in the While-method, the body is a simple type, and not a function as in the For method. You can embed some other statements, like let and function-calls inside your computation-expressions, but those can impossibly execute in a while-loop more than once. builder { while foo() do printfn "step" yield bar() } Why is the while-loop not executed more than once, but merely repeated? Why the significant difference from for-loops? Better yet, is there some intended strategy for using while-loops in computation-expressions?

• Launch ms word template as new document from IE...

  - by Simon

  I have a requirement to launch .dot files (ms word templates) as new documents from the browser... Let me explain... if you click on a .dot file in Windows Explorer it opens a new document and runs any macros... you can right click and edit the template... I want to link to the files, so I use <a href="file://myserver/templates/letter.dot">Letter</a>... However this then prompts for the "Download File" dialogue box... and then if I click "Open" it opens the template in edit mode... not the required new document mode... This may be a technical impossibility but can I achieve the desired result in ActiveX or something??

• ExtJS (4.0) dynamic / lazy loading

  - by Paul

  Given a border layout with a west (navigation) and a center region. Let say I click on topic A in the west region, I want to replace (replace as in 'delete last topic') the center region with 'extjs' program code named topic_a.js I succeed in loading with this code: dynamicPanel = new Ext.Component({ loader: { url: '/www/file.htm', renderer: 'html', autoLoad: true, scripts: true } }); var oMainContainer = Ext.getCmp('maincontainer'); oMainContainer.show(); oMainContainer.add(dynamicPanel); But calling this the second time 'adds' things up in the center region and of course fails short in 'deleting', what would be a good approach?

• Automatic form generation software

  - by Jonathan

  Hi! I'm using winforms. I spend a lot of time drawing forms (maybe not a lot, but it is a boring task). To sum up... I want to develop a simple aplication that connect to a sql server database, let the user to select a table, and put the controls in a form for me (generate the designer code), based on the tipe of each column. Then my app will name each control like the column of the table, set the maxlengh property (if the type is varchar), and create a label with the same text near the control. If the column is a FK, then the app will draw a combobox and so on. I saw that Telerik Open ORM make something like this, but I only need a simple app for the IU Generation. If the same day I finish my little application I discover a tool that make the same... I will feel myself stupid :D Are there any tool out there that do this work for me? Thanks

• jQuery toggle show XHTML Smarty some clahes maybe? It doesn't show..

  - by Kyle Sevenoaks

  Hi, at this page new customer, there is something that it doesn't like, my boss asked me to make a show function that shows the new customer registration when the user clicks on the "ny kunde" button. Here is an example of the code I got working (I'm a jQuery noob). I guess there is some clash between this and the functions already installed on the page, but what? #roundbigboxnykunde is meant to be hidden on the page as on the jsfiddle example, but I have shown it to let you see what else is on the page. Code on my .tpl <button id="button1">&nbsp;</button> {literal} <script src="http://code.jquery.com/jquery-latest.js"></script> <script type="text/javascript"> $(function() { //checkbox $("#button1").click(function()1 $(".newCustomer").toggle("show"); }); });? </script> {/literal} <div class="newCustomer">... Thanks.

• Haskell - generating all paths between nodes

  - by user1460863

  I need to build a function, which return all paths between certain nodes. connect :: Int -> Int-> [[(Int,Int)]] Data.Graph library gives me usefull function 'buildG' which builds graph for me. If I call let g = buildG (1,5) [(1,2),(2,3),(3,4),(4,5),(2,5)], I will get an array where every node is mapped to his neighbours. An example: g!1 = [2] g!2 = [3,5] .. g!5 = [] I was trying to do it using list comprehensions, but I am not very good in haskell and I am getting typing error which I can't repair. connect x y g | x == y = [] | otherwise = [(x,z) | z <- (g!x), connect z y g] I don't need to worry at this moment about cycles. Here is what I want to get: connect 1 5 g = [[(1,2),(2,3),(3,4),(4,5)],[(1,2),(2,5)]]

• Deploying Rails app over VPN

  - by DavidGouge

  You'll have to bear with me as I'm not a Ruby dev, but have inherited a Ruby system. I need to deploy some changes to the app from my repository to the server. I've been instructed to run cap deploy and told that that script will get the latest code from my repository and deploy it to the server. My problem is that I have to VPN to get to the production server and the VPN client then blocks access to my local network, cutting off the repository. So my question is, how can I change my deploy.rb so that I can deploy from my local machine instead? Or is there a better way. If you need to see the deploy.rb, please let me know. Thanks Dave

• How secure is encryption?

  - by Stomped

  Let me preface this by saying I know nothing about encryption. I understand the basic concept of public key / private key encryption but I don't how easily it can be broken, if at all. If one were to believe the movies, encrypted data can be broken by a teenager with a decent computer in a few hours. I have a client who wants credit card information sent via email - encrypted of course, but I'm still not feeling terribly good about the idea. I feel it would be safer to store the info on the VPS, but even then its an unmanaged server and there's nobody watching it who knows much about security. So can anyone tell me if there's a safe way to store and/or send this data out? Thanks

• Why does Perl allow mutual "use" relationships between modules?

  - by Haiyuan Zhang

  Let's say there are two modules that mutually use each other: package a; use b; sub p {} 1; package b; use a; 1; I think that it is systematically wrong to write code like the above, because the two modules will endlessly copy each other's code to themselves, but I can successfully run the following code, which makes me very surprised. Could any of you explain all of this to me? #! /usr/bin/perl use a; a->p();

• multi-valued property query in GAE

  - by Tim

  class Person{ @Persistent private List tags = ArrayList() } I want to let the user query a person based on his/her tag, so I had my query filter like this: tags.contains(tagValue1) and if the user want to search for multiple tags, I would just add to the filter so if the user is searching for 3 tags, then the query would be tags.contains(tagValue1) && tags.contains(tagValue2) && tags.contains(tagValue3) I think this approach is wrong, because the datastore then needs to have an index that have the tags property three times... and if the user search for more than 3 tags at a time then it will be broken. What's the proper way to do this? Do you guys have any suggestions?

• mysql twitter/facebook like status feed

  - by barjonah

  Hi, I have two tables. One named status like this... user_id | status --------+----------- 1 | random status from user 1 2 | random status from user 2 3 | random message from user 3 4 | staus from user 4 1 | second status for user1 etc... and another named users_following like this... user_id | is_following --------+----------- 1 | 2 1 | 3 2 | 1 3 | 2 meaning that user 1 is following both users 2 and 3 etc... So, let's say I chose user 1. What is the best query (performance wise) to show the status updates of users that user 1 is following, in this case users 2 and 3 currently I have something like SELECT * from status WHERE user_id IN(SELECT is_following FROM users_following WHERE user_id='1') LIMIT 0,5 but I don't think this is good for performance if a user was following thousands+ of users

• Delphi: How to assign dynamically an event handler without overwriting the existing event handler?

  - by user193655

  I need to loop through Components and assign an event handler (for example Dynamically assigning OnClick event for all TButton to ShowMessage('You clicked on ' + (Sender as TButton).Name); The problem is that in some cases I alreasy assigned the TButton OnClick event. Is there a way to solve the problem? Let's imagine I have Button1 for which the harcoded onclick event handler is: ShowMessage('This is Button1'); After my "parsing" I would like that the full event handler for Button1 becomes: ShowMessage('This is Button1'); // design time event handler code ShowMessage('You clicked on ' + (Sender as TButton).Name); // runtime added Note: I am looking for a soliution that allows me to use TButton as it is without inheriting from it.

• Which display manager for a non interactive Python app and mplayer?

  - by Matt

  I am developing an application that will run on Linux to run fullscreen all the time (no menus or trays or anything will be visible). The application is going to be developed in Python, not that that matters as far as the display manager, but what I am having a hard time with is choosing a display manager. I need something with the smallest possible footprint, that will let me run a graphical Python app and have an mplayer window at the same time, at widescreen resolutions (widescreen, 16:10,16:9, etc). Other than that, it doesn't need a lot of features, but the end footprint size is the most important thing I'll be looking at. What display manager would you recommend?
