• debate: Is adding third party libraries to a war a good idea?

  - by Master Chief

  We have a debate going on . a. The "standard" way of assembling a web app. Create a WAR with all our app artifacts and all other components like hibernate and memcached etc are deployed in the tomcat/shared/lib area. b. Create a humongous war with everything included and nothing in tomcat/shared/lib. Pros for a - It keeps things modular and the war is small. Cons for a - dependency on shared/lib has to be managed especially by the deployment process. Pros for b - All dependencies are controlled by the build process removing any room for error. Cons for b - War is really, really big. If you are deploying over a network to a huge farm, then it might have an impact. want to see what thoughts others might have about this.

• git is very very slow

  - by dorelal

  My project is six months old and git is very very slow. We track around 30 files which are of size 5 MB to 50 MB. Those are binary files and we keep them in git. I believe those files are making git slow. Is there a way to kill all files of size 5MB from the repository. I know I would lose all of these files and that is okay with me. Ideally I would like a command that would list all the big files ( 5MB) . I can see the list and then I say okay go ahead and delete those files and make git faster.

• Retain Site Background and Switch Pages?

  - by yar

  I was about to redo a Rails site today using AJAX so that the background could remain in place. Then I thought, "that would be exactly like using frames," and then I thought about SEO consequences and I dropped the idea entirely and took a look around the Web. It turns out that few sites -- except for Google itself, which has the link bar at the top -- are doing this. It doesn't look impossible to do, but it's not exactly easy. Aside from Ajaxing, you have to think about updating the query-string and having SEO-friendly links (that actually don't work, but rather make background requests via Javascript). Will any of the new technologies -- HTML5, perhaps -- solve this problem and allow us to have a Web with background colors (and other static elements) that do not disappear momentarily between page refreshes? On the other hand, why are few devs doing this with current technologies? Is it just not a big deal, too complicated to implement, or....?

• Proper chart scaling in Reporting Services 2005

  - by lastas

  I'm developing a simple bar-chart in Reporting Services 2005 with a stored procedure as data-source. The values in this graph can be both positive and negative, and can span a very big range, and hence I cannot specify any non-dynamic scale that will work for all scenarios. The problem I'm facing is that the automatic scaling pretty much sucks. I get no line to show where the zero-point is, and the y-scale labels are from top to bottom: 8818 -191181 -391181 etc etc... So my question is, what is the best approach to make the scale more adapted to human reading? Is there any guide out there? Does reporting services 2008 handle this better? Also, moving away from Reporting Services is not really an option. I realize how to put values and expression in the max, min, and the gridline interval fields, although its more of a question what expressions I should put there.

• [C++] which is better, throw an exception or return nonzero value?

  - by xis19

  While you are doing C++ programming, you have two choices of reporting an error. I suppose many teachers would suggest you throw an exception, which is derived from std::exception. Another way, which might be more "C" style, is to return a non-zero value, as zero is "ERROR_SUCCESS". Definitively, return an exception can provide much more information of the error and recovery; while the code will bloat a little bit, and making exception-safe in your mind is a little difficult for me, at least. Other way like returning something else, will make reporting an error much easier; the defect is that managing recovery will be a possibly big problem. So folks, as good programmers, which would be your preference, not considering your boss' opinion? For me, I would like to return some nonzero values.

• Python - How can I make this code asynchronous?

  - by dave

  Here's some code that illustrates my problem: def blocking1(): while True: yield 'first blocking function example' def blocking2(): while True: yield 'second blocking function example' for i in blocking1(): print 'this will be shown' for i in blocking2(): print 'this will not be shown' I have two functions which contain while True loops. These will yield data which I will then log somewhere (most likely, to an sqlite database). I've been playing around with threading and have gotten it working. However, I don't really like it... What I would like to do is make my blocking functions asynchronous. Something like: def blocking1(callback): while True: callback('first blocking function example') def blocking2(callback): while True: callback('second blocking function example') def log(data): print data blocking1(log) blocking2(log) How can I achieve this in Python? I've seen the standard library comes with asyncore and the big name in this game is Twisted but both of these seem to be used for socket IO. How can I async my non-socket related, blocking functions?

For installing it on the phone, I copy the jar file from dist folder; Is my way correct? Important!:arabic words in some SonyEricsson phones are seprated and reversed, I searched the web, but I just found some topics about LWUIT and I coulden't solve it on polish!

• why can't you use the debug/release version of a lib interchangeably

  - by user205834

  In C++, most of the libs come in Debug/Release versions. Question 1. What are the big difference between Debug and Release versions (e.g. what advantages do you have using one versus the other). Question 2. A lib is just has an implementation of the functions, how does a function implementation change if you are using debug/release versions? Question 3. Can you ever build your app in debug mode and use a release version of a lib? Thanks.

• Self Modifying Python? How can I redirect all print statements within a function without touching sys.stdout?

  - by Fake Name

  I have a situation where I am attempting to port some big, complex python routines to a threaded environment. I want to be able to, on a per-call basis, redirect the output from the function's print statement somewhere else (a logging.Logger to be specific). I really don't want to modify the source for the code I am compiling, because I need to maintain backwards compatibility with other software that calls these modules (which is single threaded, and captures output by simply grabbing everything written to sys.stdout). I know the best option is to do some rewriting, but I really don't have a choice here. Edit - Alternatively, is there any way I can override the local definition of print to point to a different function? I could then define the local print = system print unless overwritten by a kwarg, and would only involve modify a few lines at the beginning of each routine.

• If I had to create a server farm what should I do? (how others companies work?)

  - by Michel

  I have a business idea but this is not really my field so I'm trying to understand what I'm really dealing with. I have a general understanding of how a web farm works, I'm a web developer and I understand the technology behind it, but I'm curious to know specifically how a web farm is set up and which professionals are involved. Things to consider probably are the hardware, the power supply, the software managment, the cooling system and if possible the usage of green technology/power recycling. Basically, can you explain me how a web hosting company is structured and how it works? A big question, I know, but from what I already read here about the subject a lot of you know this stuff. Thanks for your time guys!

• web service data type (contract)

  - by cyberguest

  hi, i have a general design question. we have a fairly big data model that represents an clinical object, the object itself has 200+ child attributes in the hierarchy. and we have a SetObject operation, and a GetObject operation. my question is, best practice wise, would it make sense to use that single data model in both operations or different data model for each? Because the Get operation will return much more details than what's needed for Set. an example of what i mean: the data model has say ProviderId, and ProviderName attributes, in the Get operation, both the ProviderId, and ProviderName would need to be returned. However, in the Set operation, only the ProviderId is needed, and ProviderName is ignored by the service since system has that information already. In this case, if the Get and Set operations use the same data model, the ProviderName is exposed even for Set operation, does that confuse the consuming developer?

• Multiple row insertion in a faster way

  - by Cyborgo

  Hi, I am using rails and I am trying to insert new rows into the table. The data comes from a text file and I created hash with one of the attribute as key. Then I find all the keys that are currently not in the table. Then I need to insert all of them into the table with all the attributes that I saved in hash. newvals.each{ |x| author = Author.create(:first => x, :second => hash[x][0], :third => hash[x][1]) author.save } This has lot of overhead as it makes an SQL update one at time. The newals array is usually quite big around the size of 20-30k. I know create can insert multiple objects at once, but I cant seem to figure out how. Is there any way to get this done. Thanks.

• How to predict result set row count?

  - by Saurabh Kumar

  I have an application where I create a big SQL query dynamically for SQL server 2008. This query is based on various search criteria which the user might give such as search by lastname, firstname, ssn etc. The requirement is that if the user gives a condition due to which the formed query might return a lot of rows(configurable for max N rows), then the application must send back a message instead to the user saying that he needs to refine his search query as the existing query will return too many rows. I would not want to bring back say, 5000 rows to the client and then discard that data just to show the user an error. What is an efficient way to tackle this issue?

• How to make a UILabel which adjusts it's text to the upper left?

  - by mystify

  For some strange reason, in iPhone OS 3.0 this doesn't work: I made a big fullscreen UILabel with numberOfLines = 0 and baselineAdjustment = UIBaselineAdjustmentNone. It refuses to show the text in the upper left. It's always in the center of the bounding box, aligned to the left. The documentation says: UIBaselineAdjustmentNone Adjust text relative to the top-left corner of the bounding box. This is the default adjustment. Available in iPhone OS 2.0 and later. Probably a framework bug? I started with shiny new labels to test it. Text is centered.

• CouchDB: How to change view function via javascript?

  - by osti

  Hello Guys, I am playing around with CouchDB to test if it is "possible" [1] to store scientific data (simulated and experimental raw data + metadata). A big pro is the schema-less approach of CouchDB: we have to be very flexible with the metadata, as the set of parameters changes very often. Up to now I have some code to feed raw data, plots (both as attachments), and hierarchical metadata (as JSON) into CouchDB documents, and have written some prototype Javascript for filtering and showing. But the filtering is done on the client side (a.k.a. browser): The map function simply returns everything. How could I change the (or push a second) map function of a specific _design-document with simple browser-JS? I do not think that a temporary view would yield any performance gain... Thanks for your time and answers. [1]: of course it is possible, but is it also useful? feasible? reasonable?

• JQuery-code on different content pages

  - by Ockonal

  Hello, I have a site with menu, which reloads content. Content is dynamically loadable, using ajax and php-script. At different content pages I need in different jquery-plugins. But If I'm writing including need plugin directly in some content page, I get a big lags during loading. So, now I'm includgin all plugins into main page... And it's not the best idea... Any suggestion? UPD: I have a div with content. Content is shown with effects (rolling up/down). When part of menu is clicked, I'm sending ajax-responce to the php script, which reads need text from database and returns it to the main page, from which I sent the responce. Than I'm pasting that content into a div and roll id down. So I'll include jquery-plugins in content pages, the animation of rolling will'nt be normal.

• C#: reading in a text file more 'intelligently'

  - by DarthSheldon

  I have a text file which contains a list of alphabetically organized variables with their variable numbers next to them formatted something like follows: aabcdef 208 abcdefghijk 1191 bcdefga 7 cdefgab 12 defgab 100 efgabcd 999 fgabc 86 gabcdef 9 h 11 ijk 80 ... ... I would like to read each text as a string and keep it's designated id# something like read "aabcdef" and store it into an array at spot 208. The 2 issues I'm running into are: I've never read from file in C#, is there a way to read, say from start of line to whitespace as a string? and then the next string as an int until the end of line? given the nature and size of these files I do not know the highest ID value of each file (not all numbers are used so some files could house a number like 3000, but only actually list 200 variables) So how could I make a flexible way to store these variables when I don't know how big the array/list/stack/etc.. would need to be.

• using both layout-land and onConfigurationChanged()

  - by joe

  I just want to change Layout when the device has been rotated. but I've found that onConfigurationChanged() must call onCreate() again using setContentView with separated layout named of *_land.xml if(getActivity().getWindowManager().getDefaultDisplay(). getRotation() == Surface.ROTATION_0) view = inflater.inflate(R.layout.fragment_layout, null); else view = inflater.inflate(R.layout.fragment_layout_land, null); Project is too big and there are many codes to fix If onCreate again without finish(). I'd like somebody help this. Thank you. - onConfigurationChanged concept is keep layout I think

• Interpreted vs. Compiled Languages for Web Sites (PHP, ASP, Perl, Python, etc.)

  - by Andrew Swift

  I build database-driven web sites. Previously I have used Perl or PHP with MySQL. Now I am starting a big new project, and I want to do it in the way that will result in the most responsive possible site. I have seen several pages here where questions about how to optimize PHP are criticized with various versions of "it's not worth going to great lengths to optimize PHP since it's an interpreted language and it won't make that much difference". I have also heard various discussions (especiallon on the SO podcast) about the benefits of compiled vs. interpreted languages, and it seems as though it would be in my interests to use a compiled language to serve up the site instead of an interpreted language. Is this even possible in a web context? If so, what would be a reasonable language choice? In addition to speed one benefit I forsee is the possiblity of finding bugs at compile time instead of having to debug the web site. Is this reasonable to expect?

• Sphinx without using an auto_increment id

  - by squeeks

  I am current in planning on creating a big database (2+ million rows) with a variety of data from separate sources. I would like to avoid structuring the database around auto_increment ids to help prevent against sync issues with replication, and also because each item inserted will have a alphanumeric product code that is guaranteed to be unique - it seems to me more sense to use that instead. I am looking at a search engine to index this database with Sphinx looking rather appealing due to its design around indexing relational databases. However, looking at various tutorials and documentation seems to show database designs being dependent on an auto_increment field in one form or another and a rather bold statement in the documentation saying that document ids must be 32/64bit integers only or things break. Is there a way to have a database indexed by Sphinx without auto_increment fields as the id?

• Optimal strategy to make a C++ hash table, thread safe

  - by Ajeet

  (I am interested in design of implementation NOT a readymade construct that will do it all.) Suppose we have a class HashTable (not hash-map implemented as a tree but hash-table) and say there are eight threads. Suppose read to write ratio is about 100:1 or even better 1000:1. Case A) Only one thread is a writer and others including writer can read from HashTable(they may simply iterate over entire hash table) Case B) All threads are identical and all could read/write. Can someone suggest best strategy to make the class thread safe with following consideration 1. Top priority to least lock contention 2. Second priority to least number of locks My understanding so far is thus : One BIG reader-writer lock(semaphore). Specialize the semaphore so that there could be eight instances writer-resource for case B, where each each writer resource locks one row(or range for that matter). (so i guess 1+8 mutexes) Please let me know if I am thinking on the correct line, and how could we improve on this solution.
