• Localization as an afterthought-- screwed?

  - by David

  So I signed on with a startup web development company as a subcontractor. They are putting together a large, complex user/product management system for a company that needs to support multiple levels of hierarchial localization. I signed a 3 month contract, and upon looking at their code, wish I hadn't. They opted to write their own MVC framework (I guess the client company didn't want to use a prewritten one) and it's extremely poorly written. There's SQL scattered throughout almost every model view and controller (and there's no parameter-based find methods, it's all SQL) and they haven't even THOUGHT about localization yet-- something that will have an affect on nearly EVERY query. The due date is 4 months away, and I honestly think we'd make good progress by scrapping the whole thing and going with CakePHP. Have any of you been in a similar situation, and what did you do? PS: This is written in PHP/MySQL.

• String Matching.

  - by Harikrishna

  I have a string String mainString="///BUY/SELL///ORDERTIME///RT///QTY///BROKERAGE///NETRATE///AMOUNTRS///RATE///SCNM///"; Now I have another strings String str1= "RT"; which should be matched only with RT which is substring of string mainString but not with ORDERTIME which is also substring of string mainString. String str2= "RATE" ; And RATE(str2) should be matched with RATE which is substring of string mainString but not with NETRATE which is also substring of string mainString. How can we do that ?

• Creating a Rails query from a hash of user input

  - by Jamie

  I'm attempting to create a fairly complex search engine for a project using a variable number of search criteria. The user input is sorted into an array of hashes. The hashes contain the following information: { :column => "", :value => "", :operator => "", # Such as: =, !=, <, >, etc. :and_or => "", # Two possible values: "and" and "or" } How can I loop through this array and use the information in these hashes to make an ActiveRecord WHERE query?

• How to parse the MailMessage object from raw email string

  - by Xmindz

  I have written a program in C# which connects to a POP Server and retrieves raw email message strings from the server using POP3 command RETR. Since the email message being retrieved by the program is in plain text format with all the headers and message body with in the same, its too difficult to extract each header and mail body from the raw string. Could anybody tell me a solution by which I can parse the entire raw text to a System.Net.Mail.MailMessage object? Following is a sample email raw string: +OK 1281 octets Return-Path: <[email protected]> Delivered-To: samplenet-sample:[email protected] X-Envelope-To: [email protected] Received: (qmail 53856 invoked from network); 22 Sep 2012 06:11:46 -0000 Received: from mailwash18.pair.com (66.39.2.18) MIME-Version: 1.0 From: "Deepu" <[email protected]> To: [email protected] Date: 22 Sep 2012 11:41:39 +0530 Subject: TEST Subject Content-Type: text/plain; charset=us-ascii Content-Transfer-Encoding: quoted-printable Message-Id: <[email protected]> TEST Body .

• mysql: encrypting and decrypting data

  - by cbrulak

  Does mysql provide a mechanism for storing and retrieving encrypted data? I don't mean passwords, I mean real strings. I'd like to encrypt a string, store in mysql and then retrieve the decrypted string at a later date. So, I know there is the AES_Encrypt and decrypt functions. But they ask for a key. (which is fine) but I wondering if you call those functions and use your user password as the key. Or something else that is super-simple. Also, is there a simple wrapper for the AES_Encrypt & decrypt functions in Rails? Or do you need to build the query manually?

• Grabbing random object from ArrayList is not random.

  - by Isai

  I am creating a method where if you pass in a parameter of type Random, then it will return a random object. Here is basically what I am trying to do: public T choose(Random r) { int randomInt = r.nextInt(randomList.size()); // randomList is just a instance variable return randomList.get(randomInt); } The random list has this the following strings:[2, 2, 2, 1, 1, 1, 1, c, c, c, a, a, a, a] Then I made a driver with the following code for (int i = 0; i < 10; i++) { System.out.print(rndList.choose(rnd)); // rnd is initialized as a static Random variable } However my outputs are not coming out random. I used the debugger and found out that my choose method generates an integer that is relatively low, so it will always print out either 2's or 1's but never c's or a's. I can't figure out why this is happening and help would be greatly appreciated.

• Thoughts on using Alpha Five v10 with Codeless AJAX for building an AJAX database app in a short amo

  - by william Hunter

  I need to build an AJAX application against our MS SQL Server database for my company. the app has to have user permissions and reporting and is pretty complex. I am really under the gun in terms of time. The company that I work for needs the app for an important project launch. A colleague/friend of mine in a different company recommended that I look at a product from Alpha Software called Alpha Five v10 with Codeless AJAX. He has told me that he has used it extensively and that it saves him a "serious boat load of time" and he says that he has not run into limitations because you can also write your own JavaScript or you wire in jQuery. Before I commit to Alpha Five v10, I would like to get any other opinions? Thanks. Norman Stern. Chicago

• How can I temporarily redirect printf output to a c-string?

  - by Ben S

  I'm writing an assignment which involves adding some functionality to PostgreSQL on a Solaris box. As part of the assignment, we need to print some information on the client side (i.e.: using elog.) PostgreSQL already has lots of helper methods which print out the required information, however, the helper methods are packed with hundreds of printf calls, and the elog method only works with c-style strings. Is there I way that I could temporarily redirect printf calls to a buffer so I could easily send it over elog to the client? If that's not possible, what would be the simplest way to modify the helper methods to end up with a buffer as output?

• iPhone Internationalization. What is the simplest workflow for me?

  - by dugla

  Hello, I am wising up and getting my internationalization act together. Right off the bat I am a bit swamped by all the docs Apple provides so I was wondering of someone could sketch a workflow for my situation. Before I begin, I browsed some Apple example code and noticed this NIB file - MainWindow.xib - in the Resources folder: This clearly has something to do with internationalization/localization. Could someone please explain how this is created and where in the workflow it happens? My app is fundamentally an imaging app with a few labels that I currently programmatically internationalize using NSLocalizedString(...). If I set all my labels programmatically and wrap all my strings with NSLocalizedString(...) can I completely ignore the NIB issues? Thanks in advance, Doug

• C#/ASP.NET MVC 4 Instantiate Object Derived From Interface In Factory Method

  - by Chris

  Currently have a Factory class that features a GetSelector function, which returns a concrete implementation of ISelector. I have several different classes that implement ISelector and based on a setting I would like to receive the appropriate ISelector back. public interface ISelector { string GetValue(string Params); } public class XmlSelector : ISelector { public string GetValue(string Params) { // open XML file and get value } } public static class SelectorFactory { public static ISelector GetSelector() { return new XmlSelector(); // Needs changing to look at settings } } My question is what is the best way to store the setting? I am aware of using AppSettings etc. but I'm not sure whether I want to have to store strings in the web.config and perform a switch on it - just seems to be really tightly coupled in that if a new implementation of ISelector is made, then the Factory would need to be changed. Is there any way of perhaps storing an assembly name and instantiating based on that? Thanks, Chris

• TreeMap randomly stops properly returning values

  - by smessing

  I have the following TreeMap: TreeMap<String, Integer> distances = new TreeMap<String, Integer>(); and it contains both strings, "Face" and "Foo", with appropriate values, such that: System.out.println(distances); Yields: {Face=12, Foo=2} However, distances.get(Face) returns null, even though distances.get(Foo) properly returns 2. Previously, distances.get(Face) worked, but for some reason, it stopped working. Note I print out the map right before calling get() for both keys, so I haven't accidentally changed Face's value to null. Has anyone else ever encountered this problem? Is there anything I can do? I'm having a terrible time simply trying to figure out how to debug this problem.

• Rewriting Live TCP Streams

  - by user213060

  I want to rewrite TCP/IP streams. Ettercap's etterfilter command lets you perform simple live replacements of TCP/IP data based on fixed strings or regexes. Example: http://ettercap.sourceforge.net/forum/viewtopic.php?t=2833 I would like to rewrite streams based on my own filter program instead of just simple string replacements. Anyone have an idea of how to do this? Is there anything other than Ettercap that can do live replacement like this, maybe as a plugin to a VPN software or something? Thanks!

• What considerations need to be made when transitioning an application to support?

  - by Eric U.

  I will be taking on the role of support for a complex application that is transitioning from the development team. This application is a sharepoint solution that connects to several (7) web services. The development team is rolling off almost immediately and will be available only for small questions. I'm new to this role so I'm wondering what suggestions you have for me as I take on this large project. What are some considerations that should be made so that the transition to support is smooth and uninterupted? I've been reading the documentation but I can already see some gaps that need to be filled. The applicaiton is very (perhaps overly) configurable and there is lots of injected code. Stepping through the code is about the only way I can gain an understanding of what is actually happening. At this point I'm a little over whelmed and appreciate any suggestions or advice. Thanks!

• cannot output a json encoded dict containing accents (noob inside)

  - by user296546

  Hi all, here is a fairly simple example wich is driving me nuts since a couple of days. Considering the following script: # -*- coding: utf-8 -* from json import dumps as json_dumps machaine = u"une personne émérite" print(machaine) output = {} output[1] = machaine jsonoutput = json_dumps(output) print(jsonoutput) The result of this from cli: une personne émérite {"1": "une personne \u00e9m\u00e9rite"} I don't understand why their such a difference between the two strings. i have been trying all sorts of encode, decode etc but i can't seem to be able to find the right way to do it. Does anybody has an idea ? Thanks in advance. Matthieu

• C#: Messaging in local network

  - by Richard

  Hi All, I need to implement some form of communitcation mechanism in my application, to send Notifications/messages from one Application instance to all the others. This is a normal scenario where someone adds and item or deletes and item and you want to notify other users that this has happened. The application runs on the Client and connects to a database on the local network. So its not like all clients access a server instance of the application. So from what I know I could use MessageQueues or some form of Database polling where I have a table that stores all the messages (not ideal). Issue is I need to implement this very quickly, so sadly can't go very complex but need the quickest easiest solution. thanks for the help!

• Java: Parse Australian Street Addresses

  - by bguiz

  Looking for a quick and dirty way to parse Australian street addresses into its parts: 3A/45 Jindabyne Rd, Oakleigh, VIC 3166 should split into: "3A", 45, "Jindabyne Rd" "Oakleigh", "VIC", 3166 Suburb names can have multiple words, as can street names. See: http://stackoverflow.com/questions/1739746/parse-a-steet-address-into-components Has to be in Java, cannot make http requests (e.g. to web APIs). EDIT: Assume that format specified is always followed. I have no issue with spitting incorrectly formatted strings back at the user with a message telling them to follow the format (which I've described above).

• java reading numbers, interpreting as octal, want interpreted as string

  - by user331401

  hello, i am having an issue, where java is reading an array list from a YAML file of numbers, or strings, and it is interpreting the numbers as octal if it has a leading 0, and no 8-9 digit. is there a way to force java to read the yaml field as a string? code: ArrayList recordrarray = (ArrayList) sect.get("recordnum"); if (recordrarray != null) { recno = join (recordrarray, " "); } HAVE ALSO TRIED: Iterator<String> iter = recordrarray.iterator(); if (iter.hasNext()) recno = " " +String.valueOf(iter.next()); System.out.println(" this recnum:" + recno); while (iter.hasNext()){ recno += ""+String.valueOf(iter.next())); System.out.println(" done recnum:" + String.valueOf(iter.next())); } the input is such: 061456 changes to 25390 061506 changes to 25414 061559 - FINE it took a while to figure out what it was doing, and apparently this is a common issue for java, ideas? thanks

• Representing a schedule in a database

  - by David Pfeffer

  I have the interesting problem of representing complex schedule data in a database. I need to be able to represent the entirety of what the iCalendar (ics) format can represent, but in my database. I don't care about insertion efficiency but query efficiency is critical. The operation I will be doing most often is providing either a single date/time or a date/time range, and trying to determine if the defined schedule matches any part of the date/time range. Other operations can be slower. For those unfamiliar, ics allows representation of a single event or a reoccuring event based on multiple times per day, days of the week, week of a month, month, year, or some combination of those. For example, the third Thursday in November, or the 25th of December, or every two weeks starting November 2nd and continuing until September the following year. Any suggestions?

• class method or named_scope?

  - by Hadi

  i would like to have your opinion in a project i am currently working on. class Product has_many :orders end class Order attr_accessor :deliverable # to contain temporary data on how many items can be delivered for this order belongs_to :product end somehow i want to have Order.all_deliverable that will calculate the Product's quantity, subtract from list of Orders until the Product is empty or there is no more Order for this Product to illustrate Product A, quantity: 20 Product B, quantity: 0 Order 1, require Product A, quantity: 12 Order 2, require Product B, quantity: 10 Order 3, require Product A, quantity: 100 so if i call Order.all_deliverable, it will give Order 1, deliverable:12 Order 3, deliverable: 8 #(20-12) i have been thinking on using named_scope, but i think the logic will be too complex to be put in a named_scope. Any suggestion? the pseudo code for all_deliverable will be something like this: go to each orders find the remaining quantity for specific product deduct the product to max amount of order, if product is not enough, add the maximum product add to the order end From what i read around in the web, named_scope deal mostly like find and have not many method calling and looping.

• What web server should I use if I want to run Java code behind?

  - by Boaz

  At the moment, I have lot's of Java which does all kind of nifty stuff and I'm happy with it. The code is command line driven which have been great so far, but I recently decided I want to make the functionality available through web-services. Since my is complex and I'm happy with the way it's written , I don't want go through the pain of porting it to other languages. So I set out on a google journey to find out what web servers exist (on a Linux machine, though it's interesting to hear the answer without that limitation). From what I could find, it seems that there are two viable options: Apache Tomcat and Sun Java Server. What are the reason to choose one on top of the other? what are the strength of each and what are the weaknesses? Or, perhaps, there is a third one which is much easier, flexible and less cumbersome. Anyone?

• break dataframe into subsets by factor values, send to function that returns glm class, how to recom

  - by Alex Holcombe

  Thanks to Hadley's plyr package ddply function we can take a dataframe, break it down into subdataframes by factors, send each to a function, and then combine the function results for each subdataframe into a new dataframe. But what if the function returns an object of a class like glm or in my case, a c("glm", "lm"). Then, these can't be combined into a dataframe can they? I get this error instead Error in as.data.frame.default(x[[i]], optional = TRUE, stringsAsFactors = stringsAsFactors) : cannot coerce class 'c("glm", "lm")' into a data.frame Is there some more flexible data structure that will accommodate all the complex glm class results of my function calls, preserving the information regarding the dataframe subsets? Or should this be done in an entirely different way?

• How to save big "database-like" class in python

  - by Rafal

  Hi there, I'm doing a project with reasonalby big DataBase. It's not a probper DB file, but a class with format as follows: DataBase.Nodes.Data=[[] for i in range(1,1000)] f.e. this DataBase is all together something like few thousands rows. Fisrt question - is the way I'm doing efficient, or is it better to use SQL, or any other "proper" DB, which I've never used actually. And the main question - I'd like to save my DataBase class with all record, and then re-open it with Python in another session. Is that possible, what tool should I use? cPickle - it seems to be only for strings, any other? In matlab there's very useful functionality named save workspace - it saves all Your variables to a file that You can open at another session - this would be vary useful in python!

• Looking for an alternative to cfdump

  - by invertedSpear

  I think I just realized how restrictive my web host is when they wouldn't let me use cfdump. This actually kind of angers me, cause really, what harm is dump going to do? Anyway my question is has anyone written a cfdump alternative that will kick out complex types of data or can link me to a site with a code example? Can't really used cfc's or udfs either cause guess what, they're blocked too. Anyway looking for something simple that I can just paste in my cfml and I will be happy. It's sad that I used to be able to do this, but have forgotten a lot of that skillset since I moved into Flex and AS. oh and they're using cf7, so no cf8 or 9 tricks ;-) Thanks in advance.

• asp.net free webcontrol to display crosstab or pivot reports with column and row grouping, subtotals

  - by dev-cu

  Hello, I want to develop some crosstab also know as pivot reports in Asp.net with x-axis and y-axis being dynamics, allowing grouping by row and column, for example: have products in y-axis and date in x-axis having in body number of sells of a given product in a given date, if date in x-axis are years, i want subtotals for each month for a product (row) and subtotals of sells of all products in date (column) I know there are products available to build reports, but i am using Mysql, so Reporting Service is not an option. It's not necessary for the client build additional reports, i think the simplest solution is having a control to display such information and not using crystal report (which is not free) or something more complex, i want to know if is there an available free control to reach my goal. Well, does anybody know a control or have a different idea, thanks in advance.
