• What's the best license for my website?

  - by John Maxim

  I have developed a unique website but do not have a lot of fund to protect it with trademark or patents. I'm looking for suggestions so that when my supervisor gets my codes, some laws restrict anyone from copying it and claim their work. I'm in the middle of thinking, making the application a commercial one or never allowing it to be copied at all. What kind of steps am I required to take in order to make full measurements so my applications are fully-protected? I've come across a few, one under my consideration is MIT license. Some say we can have a mixture of both commercial and MIT. I would also like to be able to distribute some functions so it can be modified by others but I'd still retain the ownership. Last but not least, it's confusing when I think of protecting the whole website, and protecting codes by codes in division. How should we go about this? Thanks. N.B I have to pass it over to the supervisor as this is a Uni project. I need this to be done within 2 weeks. So time to get my App protected is a factor here.

• How do I Delete a View? How do I Create a View?

  - by Paula DiTallo

  Before I create views, I generally work out what I want to retrieve in my SELECT statement ahead of time so I'll just  have to cut and  paste the query. The example below is done  in T-SQL/Sybase format, however for Oracle and MySQL, just  place a semi-colon ';' at the end of your statement and remove the  'GO' command.          To drop (delete) an existing view: DROP VIEW vw_rpt_metroBestCustomers GO To create a view: CREATE VIEW vw_rpt_metroBestCustomers ( CustomerName,    OfficeNum,    City,    StateOrProv,    Country,    ZipCode   ) AS SELECT a.FirstName + ', ' + a.LastName,           b.OfficePhoneNum,           c.City,           c.StateOrProvAbbr,           c.Country,           c.PostalCode     FROM Customer a,          CustLocAssoc x,          CustContactAssoc y,          Location c,          Contact b     WHERE a.CustID = x.CustID       AND a.CustID = y.CustID       AND y.ContactID = b.ContactID       AND x.LocID = c.LocID       AND a.LoyaltyMedian > 85.5 GO        I frequently rename columns when developing views to makeit easier for simple, text-based reporting--however, renamingthe columns isn't necessary.The create view statement above could have been writtenas follows:CREATE VIEW vw_rpt_metroBestCustomersAS (SELECT a.FirstName + ', ' + a.LastName, b.OfficePhoneNum, c.City, c.StateOrProvAbbr, c.Country, c.PostalCode FROM Customer a, CustLocAssoc x, CustContactAssoc y, Location c, Contact b WHERE a.CustID = x.CustID AND a.CustID = y.CustID AND y.ContactID = b.ContactID AND x.LocID = c.LocID AND a.LoyaltyMedian > 85.5 )GO

• How to write a very basic compiler [closed]

  - by Ali

  Possible Duplicate: Best Online resources to learn about Compilers? What would be the best way to learn about compilers, and executable formats? Advanced compilers like gcc compile codes into machine readable files according to the language in which the code has been written (e.g. C, C++, etc). In fact, they interpret the meaning of each codes according to library and functions of the corresponding languages. Correct me if I'm wrong. I wish to better understand compilers by writing a very basic compiler (probably in C) to compile a static file (e.g. Hello World in a text file). I tried some tutorials and books, but all of them are for practical cases. They deal with compiling dynamic codes with meanings connected with the corresponding language. How can I write a basic compiler to convert a static text into a machine readable file? The next step will be introducing variables into the compiler; imagine that we want to write a compiler which compile only some functions of a language. Introducing practical tutorials and resources is highly appreciated :-)

• from Java to SAS

  - by Giovanni Rossi

  I am a seasoned python,java,...other programmer having a (fairly advanced) mathematical education (so I do understand statistics and data mining, for example) . For various reasons I am thinking to switch to SAS/BI area (I am naming SAS because it might be, for me, a possible way to enter in BI). My question, for whoever might have an experience of both: is it, in BI current state, worth it? I mean, the days of big ideas in BI for business seem to be over (there are the APIs, managers think that they know what you can do with them), and my mathematical background might turn out to be superflous. Also, the big companies now have their data organized, have their BI procedures well established, and trying to analyze it from a different standpoint might not be what they want. Another difference is: while in Java etc. development one codes and codes and codes, I don't know if this is the case for BI; in fact, from what I read on the net, a BI (or OLAP, ...etc) developer, in a big organization, is usually in a state of standby, and does in fact little coding. Any opinions, and in particular strong opinions, will be appreciated.

• When must I turn my business idea into a formal Company? [closed]

  - by Sony Santos

  I'm a programmer, I have an idea, I know how to implement it, it will be a website, and that site will be my business. My question is very basic: where in timeline must I register my business as an official Company (ie, according Government laws)? Here there are some options to debate or to help answer me: Now - or as soon as I have the idea; When looking for investors (e.g., when a prototype or business plan is ready); When implementing the website; At site's launch; I must launch the website as a personal informal business and, when the business gets success and turns into a more solid and self-running one, only then I must formalize it; It doesn't matter; I can create the company when I want. Nobody talks about that. If I just have an idea, must I run into an office to create a Company? I don't think so. When I'll look for investors, the Company must to pre-exist? Or will the Company be formed with the investor? I'm looking for a generic, country-independent answer, but may the answer for your country can be useful to me. I'm Brazilian, and I believe that the country doesn't matter to this question. (Sorry if this is off-topic, but I coudn't find a batter stackexchange site to ask this.)

• Can we use both Google Analytics (Asynchronous) and Google Analytics with Display Advertising code in same page

  - by Gadde

  I have Google Analytics (Asynchronous) script <script type=”text/javascript”> _gaq.push(['_setAccount', 'UA-XXXXX-X']); _gaq.push(['_trackPageview']); (function() { var ga = document.createElement('script'); ga.type = 'text/javascript'; ga.async = true; ga.src = ('https:' == document.location.protocol ?

'https://' : 'http://') + 'stats.g.doubleclick.net/dc.js'; var s = document.getElementsByTagName('script')[0]; s.parentNode.insertBefore(ga, s); })(); </script> The UA - codes are different can i use both the codes ? I've read some where that Universal Analytics will not interfere with previous versions of Google Analytics. If i have upgraded to Universal Analytics, If the UA - codes are different should i use only the Universal Analytics script or should i use both Universal Analytics script and Universal Analytics script. please advise.....

• Trying to filter a ListView with runQueryOnBackgroundThread but nothing happens - what am I missing?

  - by Ian Leslie

  I have a list of countries in a database. I have created a select country activity that consists of a edit box for filtering and a list which displays the flag and country name. When the activity starts the list shows the entire list of countries sorted alphabetically - works fine. When the customer starts typing into the search box I want the list to be filtered based on their typing. My database query was previously working in an AutoCompleteView (I just want to switch to a separate text box and list) so I know my full query and my constraint query are working. What I did was add a TextWatcher to the EditText view and every time the text is changed I invoke the list's SimpleCursorAdapter runQueryOnBackgroundThread with the edit boxes text as the constraint. The trouble is the list is never updated. I have set breakpoints in the debugger and the TextWatcher does make the call to runQueryOnBackgroundThread and my FilterQueryProvider is called with the expected constraint. The database query goes fine and the cursor is returned. The cursor adapter has a filter query provider set (and a view binder to display the flag): SimpleCursorAdapter adapter = new SimpleCursorAdapter (this, R.layout.country_list_row, countryCursor, from, to); adapter.setFilterQueryProvider (new CountryFilterProvider ()); adapter.setViewBinder (new FlagViewBinder ()); The FitlerQueryProvider: private final class CountryFilterProvider implements FilterQueryProvider { @Override public Cursor runQuery (CharSequence constraint) { Cursor countryCursor = myDbHelper.getCountryList (constraint); startManagingCursor (countryCursor); return countryCursor; } } And the EditText has a TextWatcher: myCountrySearchText = (EditText)findViewById (R.id.entry); myCountrySearchText.setHint (R.string.country_hint); myCountrySearchText.addTextChangedListener (new TextWatcher() { @Override public void afterTextChanged (Editable s) { SimpleCursorAdapter filterAdapter = (SimpleCursorAdapter)myCountryList.getAdapter (); filterAdapter.runQueryOnBackgroundThread (s.toString ()); } @Override public void onTextChanged (CharSequence s, int start, int before, int count) { // no work to do } @Override public void beforeTextChanged (CharSequence s, int start, int count, int after) { // no work to do } }); The query for the database looks like this: public Cursor getCountryList (CharSequence constraint) { if (constraint == null || constraint.length () == 0) { // Return the full list of countries return myDataBase.query (DATABASE_COUNTRY_TABLE, new String[] { KEY_ROWID, KEY_COUNTRYNAME, KEY_COUNTRYCODE }, null, null, null, null, KEY_COUNTRYNAME); } else { // Return a list of countries who's name contains the passed in constraint return myDataBase.query (DATABASE_COUNTRY_TABLE, new String[] { KEY_ROWID, KEY_COUNTRYNAME, KEY_COUNTRYCODE }, "Country like '%" + constraint.toString () + "%'", null, null, null, "CASE WHEN Country like '" + constraint.toString () + "%' THEN 0 ELSE 1 END, Country"); } } It just seems like there is a missing link somewhere. Any help would be appreciated. Thanks, Ian

• populate CoreData data model from JSON files prior to app start

  - by johannes_d

  I am creating an iPad App that displays data I got from an API in JSON format. My Core Data model has several entities(Countries, Events, Talks, ...). For each entity I have one .json file that contains all instances of the entity and its attributes as well as its relationships. I would like to populate my Core Data data model with these entities before the start of the App (otherwise it takes about 15 minutes for the iPad to create all the instances of the entities from the several JSON files using factory methods). I am currently importing the data into CoreData like this: -(void)fetchDataIntoDocument:(UIManagedDocument *)document { dispatch_queue_t dataQ = dispatch_queue_create("Data import", NULL); dispatch_async(dataQ, ^{ //Fetching data from application bundle NSURL *tedxgroupsurl = [[NSBundle mainBundle] URLForResource:@"contries" withExtension:@"json"]; NSURL *tedxeventsurl = [[NSBundle mainBundle] URLForResource:@"events" withExtension:@"json"]; //converting the JSON files to NSDictionaries NSError *error = nil; NSDictionary *countries = [NSJSONSerialization JSONObjectWithData:[NSData dataWithContentsOfURL:countriesurl] options:kNilOptions error:&error]; countries = [countries objectForKey:@"countries"]; NSDictionary *events = [NSJSONSerialization JSONObjectWithData:[NSData dataWithContentsOfURL:eventsurl] options:kNilOptions error:&error]; events = [events objectForKey:@"events"]; //creating entities using factory methods in NSManagedObject Subclasses (Country / Event) [document.managedObjectContext performBlock:^{ NSLog(@"creating countries"); for (NSDictionary *country in countries) { [Country countryWithCountryInfo:country inManagedObjectContext:document.managedObjectContext]; //creating Country entities } NSLog(@"creating events"); for (NSDictionary *event in events) { [Event eventWithEventInfo:event inManagedObjectContext:document.managedObjectContext]; // creating Event entities } NSLog(@"done creating, saving document"); [document saveToURL:document.fileURL forSaveOperation:UIDocumentSaveForOverwriting completionHandler:NULL]; }]; }); dispatch_release(dataQ); } This combines the different JSON files into one UIManagedDocument which i can then perform fetchRequests on to populate tableViews, mapView, etc. I'm looking for a way to create this document outside my application & add it to the mainBundle. Then I could copy it once to the apps DocumentsDirectory and be able I use it (instead of creating the Document within the app from the original JSON files). Any help is appreciated!

• SQLAuthority News – Tips for Traveling to Nepal

  - by pinaldave

  If you are a regular reader of this blog, you might know that I travel nearly 20+ days out of 30 days in a month. There are cases when I don’t have a chance to go home for an entire month and my family has to travel to different cities just to meet me. During my recent visit, one of my acquaintances suggested that I should blog about my travel experiences as well. This can be helpful to others who are traveling to the country or city. I have previously written about my experience about all the airlines in India. I would be writing about a few tips about traveling to the beautiful country Nepal today. Kathmandu, the capital of Nepal is very scenic. There are lots of historical places to see and visit. I was fortunate enough to stopover the Pashupatinath Temple, Bhaktapur, Vasantpur and the temple of Kumari Goddess. I also visited casinos there, but even if  I have stayed in Las Vegas for 3 and a half years before, I was not keen on them so I left the casinos just like what I did in Las Vegas . I also traveled to the famous Thamel area by car. Here are my quick tips for anyone who is planning to visit Nepal. They are not categorized but just written in the order that came to my mind. Please note that if you are an Indian, you will get a special privilege everywhere in Nepal, beginning right from the Indian airports. Use the expression “Nameste!” If you want to greet any Indian or Nepali. Indian Nationals do not need visa/passport to enter Nepal. In fact, Indian Nationals can just walk in to Nepal without any passport; but should have any valid Indian ID. There is no use of a passport since it will not be stamped at any immigration ports, whether in India or Nepal. Indian currency is widely accepted everywhere. However, please bring only Rs. 100 bills/notes as Rs. 500 or Rs. 1000 are not accepted. However, casinos there will accept larger bills. Indian National Language – Hindi is widely spoken and understood everywhere. I did not find a single person who had trouble speaking it. Nepali language uses the scripting language as Devnagari, which is similar to Hindi. Here, you will find food of almost every country.  The taste of Nepali food is authentic and very delicious. It is very safe to travel and move around in Kathmandu (despite what media suggests). However, it will really help if you have a friend who speaks Nepali. You can negotiate a few deals and cut off to almost 1/5 of the original quoted price of products sold here. If you are from Gujarat, India – you will find Nepali language sharing many common words. Temples are everywhere, so do not miss to visit a few of them. Pashupatinath is a must. Only followers of Hindu religion (from Nepal and India only) are allowed in most of the holy places. Camera is allowed everywhere except on the holy places. Now it is your turn to share your opinions or any suggestions. I think Nepal is a great country as there are lots of places to visit.

• What's wrong with my wireless?

  - by dazzle

  I am having issues with my wireless connection. My connection is constantly disconnecting, then attempting to reconnect, reconnecting momentarily, then disconnecting etc. on times scales that range from seconds to minutes. In the meantime, needless to say I'm having significant packet loss. I'm running Ubuntu 14.04 64bit, updated and upgraded to today. Here is my card and driver: delta@sager:~$ lspci -vq | grep -i wireless -B 1 -A 5 04:00.0 Network controller: Intel Corporation Wireless 7260 (rev 73) Subsystem: Intel Corporation Dual Band Wireless-AC 7260 Flags: bus master, fast devsel, latency 0, IRQ 47 Memory at f7d00000 (64-bit, non-prefetchable) [size=8K] Capabilities: Kernel driver in use: iwlwifi Here is my kernel: delta@sager:~$ uname -r 3.13.0-34-generic None of the other machines on my home network are having these issues.

• Red Meat's Music is Rare - and Well Done

  - by Oracle OpenWorld Blog Team

  By Karen Shamban The blogger has questions; San Francisco-based country band Red Meat has answers. Although we forgot to ask how they got their band name, dang it. Read on and enjoy the honesty and insight. Q. What do you like best about performing in front of a live audience?A. Probably just having fun and entertaining the audience. We've been together for almost two decades, and in that time we've played for crowds of five people, and for crowds of more than 15,000. Both are equally important to us, and just as fun. We turn Jill and Smelley loose on the between-songs repartee, and let the songs shine through. On the best night, we feed on the audience's love and vice-versa. It's emotional vampirism of the best sort. [Blogger's note: now that whole "red meat" thing is starting to make sense ...] Q. Do you prefer smaller, intimate venues or larger, louder ones? Why?A. We love both. Whether it's a chance to connect with a small room or huge audience, we always try to hit 'em between the eyes! Q. What about your fans surprises you?A. Since we've been together for so long, we're pretty much on our third generation of fans now. We're excited that the Bakersfield sound has that same effect on the new, younger fans as it did on the punk rockers that we played to 20 years ago. And we still see them at our shows too! Q. What about your live act surprises your fans?A. For people who haven't seen Red Meat before, they may be dragged to a show thinking they don't like country music. But they're surprised to hear it done in a way that excites them so much. We get a lot of first-timers coming up to us after a performance and asking, "Wait, THAT'S what country music can sound like?" Q. There are going to be a lot of technical people (you could call them geeks) in the Oracle crowd - what are they going to love about your performance?A. Just what everyone loves about a Red Meat show - the chance to drink beer, dance, get rowdy, and have a great time. Q. Have you been on tour recently? If so, what do you like about touring, and what do you dislike?A. Actually, we're going to be coming off the road immediately into the Oracle OpenWorld Music Festival, having just played some Texas dates. On tour, we love playing for fans who don't get to see us as often as our California fans do. And food. Most of our conversations in the van center around food. Q. Ever think about playing another kind of music? If so, what, and why?A. Our tastes and influences in the band run all over the place. Obviously we love the Bakersfield artists - Buck Owens, Merle Haggard, Dwight Yoakam - but we love other types of roots music as well, along with the Beatles, NRBQ, MC5, punk/new wave, and countless bar bands that we've had the privilege of playing with through the years. But as far as playing a different kind of music as Red Meat? Nah. We love what we're doing. Q. What are the top three things people should know about your music?A1. Country music, done right, has unlimited soul.A2. Red Meat is a modern band, playing original material, with a great debt to the Bakersfield sound of Buck Owens and Merle Haggard.A3. It's FUN. More details on the Festival and the band: Oracle OpenWorld Music Festival Red Meat

• Relative XPath node selection with C# XmlDocument

  - by lox

  Imagine the following XML document: <root> <person_data> <person> <name>John</name> <age>35</age> </person> <person> <name>Jim</name> <age>50</age> </person> </person_data> <locations> <location> <name>John</name> <country>USA</country> </location> <location> <name>Jim</name> <country>Japan</country> </location> </locations> </root> I then select the person node for Jim: XmlNode personNode = doc.SelectSingleNode("//person[name = 'Jim']"); And now from this node with a single XPath select I would like to retrieve Jim's location node. Something like: XmlNode locationNode = personNode.SelectSingleNode("//location[name = {reference to personNode}/name]"); Since I am selecting based on the personNode it would be handy if I could reference it in the select. Is this possible?.. is the connection there? Sure I could put in a few extra lines of code and put the name into a variable and use this in the XPath string but that is not what I am asking.

• Access custom error messages for InArray validator when using Zend_Form_Element_Select

  - by Ben Waine

  Hello, I'm using Zend Framework 1.62 (becuase we are deploying the finished product to a Red Hat instance, which doesn't have a hgih enough PHP version to support ZF1.62). When creating a Form using Zend Form, I add a select element, add some multi options. I use the Zend Form as an in-object validation layer, passing an objects values through it and using the isValid method to determine if all the values fall within normal parameters. Zend_Form_Element_Select works exactly as expected, showing invalid if any other value is input other than one of the multi select options I added. The problem comes when I want to display the form at some point, I cant edit the error message created by the pre registered 'InArray' validator added automatically by ZF. I know I can disable this behaviour, but it works great apart from the error messages. I've tryed the following: $this->getElement('country')->getValidator('InArray')->setMessage('The country is not in the approved lists of countries'); // Doesn't work at all. $this->getElement('country')->setErrorMessage('The country is not in the approved lists of countries'); // Causes a conflict elswhere in the application and doesnt allow granular control of error messages. Anyone have any ideas? Ben

• Optimize CUDA with Thrust in a loop

  - by macs

  Given the following piece of code, generating a kind of code dictionary with CUDA using thrust (C++ template library for CUDA): thrust::device_vector<float> dCodes(codes->begin(), codes->end()); thrust::device_vector<int> dCounts(counts->begin(), counts->end()); thrust::device_vector<int> newCounts(counts->size()); for (int i = 0; i < dCodes.size(); i++) { float code = dCodes[i]; int count = thrust::count(dCodes.begin(), dCodes.end(), code); newCounts[i] = dCounts[i] + count; //Had we already a count in one of the last runs? if (dCounts[i] > 0) { newCounts[i]--; } //Remove thrust::detail::normal_iterator<thrust::device_ptr<float> > newEnd = thrust::remove(dCodes.begin()+i+1, dCodes.end(), code); int dist = thrust::distance(dCodes.begin(), newEnd); dCodes.resize(dist); newCounts.resize(dist); } codes->resize(dCodes.size()); counts->resize(newCounts.size()); thrust::copy(dCodes.begin(), dCodes.end(), codes->begin()); thrust::copy(newCounts.begin(), newCounts.end(), counts->begin()); The problem is, that i've noticed multiple copies of 4 bytes, by using CUDA visual profiler. IMO this is generated by The loop counter i float code, int count and dist Every access to i and the variables noted above This seems to slow down everything (sequential copying of 4 bytes is no fun...). So, how i'm telling thrust, that these variables shall be handled on the device? Or are they already? Using thrust::device_ptr seems not sufficient for me, because i'm not sure whether the for loop around runs on host or on device (which could also be another reason for the slowliness).

• django powering multiple shops from one code base on a single domain

  - by imanc

  Hey, I am new to django and python and am trying to figure out how to modify an existing app to run multiple shops through a single domain. Django's sites middleware seems inappropriate in this particular case because it manages different domains, not sites run through the same domain, e.g. : domain.com/uk domain.com/us domain.com/es etc. Each site will need translated content - and minor template changes. The solution needs to be flexible enough to allow for easy modification of templates. The forms will also need to vary a bit, e.g minor variances in fields and validation for each country specific shop. I am thinking along the lines of the following as a solution and would love some feedback from experienced django-ers: In short: same codebase, but separate country specific urls files, separate templates and separate database Create a middleware class that does IP localisation, determines the country based on the URL and creates a database connection, e.g. /au/ will point to the au specific database and so on. in root urls.py have routes that point to a separate country specific routing file, e..g (r'^au/',include('urls_au')), (r'^es/',include('urls_es')), use a single template directory but in that directory have a localised directory structure, e.g. /base.html and /uk/base.html and write a custom template loader that looks for local templates first. (or have a separate directory for each shop and set the template directory path in middleware) use the django internationalisation to manage translation strings throughout slight variances in forms and models (e.g. ZA has an ID field, France has 'door code' and 'floor' etc.) I am unsure how to handle these variations but I suspect the tables will contain all fields but allowing nulls and the model will have all fields but allowing nulls. The forms will to be modified slightly for each shop. Anyway, I am keen to get feedback on the best way to go about achieving this multi site solution. It seems like it would work, but feels a bit "hackish" and I wonder if there's a more elegant way of getting this solution to work. Thanks, imanc

• Writing a JavaScript zip code validation function

  - by mkoryak

  I would like to write a JavaScript function that validates a zip code, by checking if the zip code actually exists. Here is a list of all zip codes: http://www.census.gov/tiger/tms/gazetteer/zips.txt (I only care about the 2nd column) This is really a compression problem. I would like to do this for fun. OK, now that's out of the way, here is a list of optimizations over a straight hashtable that I can think of, feel free to add anything I have not thought of: Break zipcode into 2 parts, first 2 digits and last 3 digits. Make a giant if-else statement first checking the first 2 digits, then checking ranges within the last 3 digits. Or, covert the zips into hex, and see if I can do the same thing using smaller groups. Find out if within the range of all valid zip codes there are more valid zip codes vs invalid zip codes. Write the above code targeting the smaller group. Break up the hash into separate files, and load them via Ajax as user types in the zipcode. So perhaps break into 2 parts, first for first 2 digits, second for last 3. Lastly, I plan to generate the JavaScript files using another program, not by hand. Edit: performance matters here. I do want to use this, if it doesn't suck. Performance of the JavaScript code execution + download time. Edit 2: JavaScript only solutions please. I don't have access to the application server, plus, that would make this into a whole other problem =)

• How do I get XML path by its value?

  - by user299938

  I need to get the xml path opf the xml file by providing the value of an xml child element as the input. For example: XML file: <?xml version="1.0"?> <document-inquiry xmlns="http://ops.epo.org"> <publication-reference data-format="docdb" xmlns="http://www.epo.org/exchange"> <document-id> <country>EP</country> <doc-number>1000</doc-number> <kind>A1</kind> </document-id> </publication-reference> </document-inquiry> For the above XML file.

• rails semi-complex STI with ancestry data model planning the routes and controllers

  - by ere

  I'm trying to figure out the best way to manage my controller(s) and models for a particular use case. I'm building a review system where a User may build a review of several distinct types with a Polymorphic Reviewable. Country (has_many reviews & cities) Subdivision/State (optional, sometimes it doesnt exist, also reviewable, has_many cities) City (has places & review) Burrow (optional, also reviewable ex: Brooklyn) Neighborhood (optional & reviewable, ex: williamsburg) Place (belongs to city) I'm also wondering about adding more complexity. I also want to include subdivisions occasionally... ie for the US, I might add Texas or for Germany, Baveria and have it be reviewable as well but not every country has regions and even those that do might never be reviewed. So it's not at all strict. I would like it to as simple and flexible as possible. It'd kinda be nice if the user could just land on one form and select either a city or a country, and then drill down using data from say Foursquare to find a particular place in a city and make a review. I'm really not sure which route I should take? For example, what happens if I have a Country, and a City... and then I decide to add a Burrow? Could I give places tags (ie Williamsburg, Brooklyn) belong_to NY City and the tags belong to NY? Tags are more flexible and optionally explain what areas they might be in, the tags belong to a city, but also have places and be reviewable? So I'm looking for suggestions for anyone who's done something related. Using Rails 3.2, and mongoid.

• merging javascript arrays for json

  - by Nat

  I serially collect information from forms into arrays like so: list = {"name" : "John", "email" : "[email protected]", "country" : "Canada", "color" : "blue"}; identifier = "first_round"; list = {"name" : "Harry", "email" : "[email protected]", "country" : "Germany"}; identifier = "second_round"; I want to combine them into something (I may have braces where I need brackets) like: list_all = { "first_round" : {"name" : "John", "email" : "[email protected]", "country" : "Canada", "color" : "blue"} , "second_round" : {"name" : "Harry", "email" : "[email protected]", "country" : "Germany"} }; so I can access them like: alert(list_all.first_round.name) -> John (Note: the name-values ("name", "email", "color") in the two list-arrays are not quite the same, the number of items in each list-array is limited but not known in advance; I need to serially add only one array to the previous structure each round and there may be any number of rounds, i.e. "third-round" : {...}, "fourth-round" : {...} and so on.) Ultimately, I'd like it to be well-parsed for JSON. I use the jquery library, if that helps.

• Getting wierd issue with TO_NUMBER function in Oracle

  - by Fazal

  I have been getting an intermittent issue when executing to_number function in the where clause on a varchar2 column if number of records exceed a certain number n. I used n as there is no exact number of records on which it happens. On one DB it happens after n was 1 million on another when it was 0.1. million. E.g. I have a table with 10 million records say Table Country which has field1 varchar2 containing numberic data and Id If I do a query as an example select * from country where to_number(field1) = 23 and id 1 and id < 100000 This works But if i do the query select * from country where to_number(field1) = 23 and id 1 and id < 100001 It fails saying invalid number Next I try the query select * from country where to_number(field1) = 23 and id 2 and id < 100001 It works again As I only got invalid number it was confusing, but in the log file it said Memory Notification: Library Cache Object loaded into SGA Heap size 3823K exceeds notification threshold (2048K) KGL object name :with sqlplan as ( select c006 object_owner, c007 object_type,c008 object_name from htmldb_collections where COLLECTION_NAME='HTMLDB_QUERY_PLAN' and c007 in ('TABLE','INDEX','MATERIALIZED VIEW','INDEX (UNIQUE)')), ws_schemas as( select schema from wwv_flow_company_schemas where security_group_id = :flow_security_group_id), t as( select s.object_owner table_owner,s.object_name table_name, d.OBJECT_ID from sqlplan s,sys.dba_objects d It seems its related to SGA size, but google did not give me much help on this. Does anyone have any idea about this issue with TO_NUMBER or oracle functions for large data?

• How to avoid using the same identifier for Class Names and Property Names?

  - by Wololo

  Here are a few example of classes and properties sharing the same identifier: public Coordinates Coordinates { get; set; } public Country Country { get; set; } public Article Article { get; set; } public Color Color { get; set; } public Address Address { get; set; } This problem occurs more frequently when using POCO with the Entity Framework as the Entity Framework uses the Property Name for the Relationships. So what to do? Use non-standard class names? public ClsCoordinates Coordinates { get; set; } public ClsCountry Country { get; set; } public ClsArticle Article { get; set; } public ClsColor Color { get; set; } public ClsAddress Address { get; set; } public ClsCategory Category { get; set; } Yuk Or use more descriptive Property Names? public Coordinates GeographicCoordinates { get; set; } public Country GeographicCountry { get; set; } public Article WebArticle { get; set; } public Color BackgroundColor { get; set; } public Address HomeAddress { get; set; } public Category ProductCategory { get; set; } Less than ideal, but can live with it I suppose. Or JUST LIVE WITH IT? What are you best practices?

• Safari Web Inspector is not updating when I update an element with ajax

  - by Ashley

  I have a checkout page http://www.oipolloi.com/oipolloi/shop/viewbasket.php with multiple ajax calls after certain items update (EG look up postage cost when country is changed, then update discount boxes etc). I've asked for help in the past about the best method of making sure ALL calls have returned before allowing the form to be submitted for payment processing: http://stackoverflow.com/questions/2290372/how-do-i-prevent-form-submission-until-multiple-ajax-calls-have-finished-jquery I was fairly happy that the logic in the finished solution was correct, but I have still been receiving reports that people using Safari are able to submit the form without the ajax calls returning properly. I have tried using the Safari Web Inspector to debug but it seems that when you Inspect Element, then update an element with an ajax call, the Inspector doesn't seem to update. I am updating hidden fields, so it's hard to be able to know whether the problem lies with the DOM not being updated properly, or the Inspector itself. I'm using Safari 4.0.5 on PC and you can reproduce the problem above by looking for a div id="countryFieldsBilling" with Web Inspector. It should contain three hidden fields that are initially empty. You can try to make it update (or not) by choosing a country from the select menu at the bottom of 'Shipping Address' box, and then clicking the 'click to use Shipping Address' link at the top of the 'Billing Address' just below. The behaviour I am seeing is that the country chosen in the shipping select gets copied correctly to the country in the billing select, but the hidden inputs in the Web Inspector do not get updated. When these hidden inputs do not get updated, this causes the problem that Mac Safari users report. If you can let me know either how to get Web Inspector to work properly, or something else I may have missed in the behaviour of Mac Safari that may cause these problems, that would be great. Thanks in advance

• How to add a WHERE clause on the second table of a 1-to-1 join in Fluent NHibernate?

  I'm using a legacy database that was 'future proofed' to keep track of historical changes. It turns out this feature is never used so I want to map the tables into a single entity. My tables are: CodesHistory (CodesHistoryID (pk), CodeID (fk), Text) Codes (CodeID (pk), CodeName) To add an additional level of complexity, these tables hold the content for the drop down lists throughout the application. So, I'm trying to map a Title entity (Mr, Mrs etc.) as follows: Title ClassMap - Public Sub New() Table("CodesHistory") Id(Function(x) x.TitleID, "CodesHistoryID") Map(Function(x) x.Text) 'Call into the other half of the 1-2-1 join in order to merge them in 'this single domain object Join("Codes", AddressOf AddTitleDetailData) Where("CodeName like 'C.Title.%'") End Sub ' Method to merge two tables with a 1-2-1 join into a single entity in VB.Net Public Sub AddTitleDetailData(ByVal m As JoinPart(Of Title)) m.KeyColumn("CodeID") m.Map(Function(x) x.CodeName) End Sub From the above, you can see that my 'CodeName' field represents the select list in question (C.Title, C.Age etc). The problem is that the WHERE clause only applies to the 'CodesHistory' table but the 'CodeName' field is in the 'Codes' table. As I'm sure you can guess there's no scope to change the database. Is it possible to apply the WHERE clause to the Codes table?
