• How to deal with 'bad' decision forced on you regarding basic software for your product

  - by raticulin

  Here is my situation, our product used to support several of the major databases. Now management has decided to move all products to MaxDB (aka SapDB previously), and even if we keep supporting some of the previous dbs, all new installations are on MaxDB. I am sure MaxDB is a great db and can support huge SAP installations. But from the point of view of a software developper, its a nightmare. Every time you need to do something not trivial (write an stored procedure, some fancy trigger...) and you google for some info, you get like 0.1% of the hits you would with things like MySql, PostgreSql or MSSql. Mailing lists are nearly non existant. SAP does support it commercially but it is not clear wether we'll buy support. And the decision cannot be rolled back. The product works with MaxDB, but with lots of inefficiency on development and a lot of frustration, is there something one could do?

• HTTPS with Self-Signed Certificate Issues... Solution or better way?

  - by stormin986

  All I need to do is download some basic text-based and image files from a web server that has a self-signed SSL certificate. I have been trying to figure out how to use HttpClient to do this, but getting the SSL to work is a nightmare that seems to be way too much trouble for such a simple task. Is there a better way to perform these file downloads? Perhaps through a WebView or Browser feature? Reinventing the wheel of making a simple HTTPS GET request is a major pain, and is significantly holding up my development schedule. ** Updated title to more accurately reflect question / solution **

• Manipulating source packages from Hackage how to easy deploy to several windowsboxes?

  - by Jonke

  Recently when I have found good sources packages for ghc 6.12/6.10 on Hackage I've been forced to do some minor or major changes to the cabal files to make those packages to work under windows. Besides to fork and merge my fixes with github, what seems to be the best way/ good enough practice to take these modified builds to a couple of other windows boxes that only has a basic haskell platform installed? I should prefer if I somehow could work with the cabal-install because that is what one normally use. Should one put the modfied build dirs on a shared/networked dir and mount from the targeted windows box? Say something like this: on machine prepare cabal fetch foo cabal unpack foo cd foo edit .cabal and .hs cabal configure cabal build On machine useanddevelopnormal cd machinepreparemount cd foo cabal install

• Task vs. process, is there really any difference?

  - by DASKAjA

  Hi there, I'm studying for my final exams in my CS major on the subject distributed systems and operating systems. I'm in the need for a good definition for the terms task, process and threads. So far I'm confident that a process is the representation of running (or suspended, but initiated) program with its own memory, program counter, registers, stack, etc (process control block). Processes can run threads which share memory, so that communication via shared memory is possible in contrast to processes which have to communicate via IPC. But what's the difference between tasks and process. I often read that they're interchangable and that the term task isn't used anymore. Is that really true?

• How to get flash player to display under content on a PC?

  - by bschaeffer

  Long story short, I'm developing a theme template for a blog that enables you to view the posts in blocks. The main part of the post is displayed at first, then the secondary content is displayed over that when you hover over the post block. Everything works fine on a Mac Versions of all major browsers, but start browsing on a PC, and all hell breaks loose when you start trying to display content over Flash Video embeds. The flash element remains visible over the content. It's completely unusable. From a PC, you can view an example of the problem here: http://photorific.tumblr.com I'm almost certain this is a bug in the Flash Plugin for Windows, but I was wondering if anyone else had come across this problem before, and if there were any solutions. This problem has presented itself for a while now and any help would be really, really, really appreciated!

• Managing the localization of Java properties files

  - by andri

  I have a Web application written in Java that is targeting several countries, all of which speak different languages (and more often than not, several languages -- that's Europe for you). We have a bunch of .properties files that hold the localized strings, and our current procedure is to e-mail the language-specific files to our partners for updating before doing major updates. However, this process is rather error-prone, as sometimes people forget to translate new strings and sometimes new strings don't get added to every language file, thus small mistakes get through very easily. Does anyone know of any existing software that could help us clear this mess? At a bare minimum, I'm thinking of something that would allow you to load a master file (for example, in English), a localized file and then would highlight the keys that were added to or removed from the master file.

• Why don't scripting languages output Unicode to the Windows console?

  - by hippietrail

  The Windows console has been Unicode aware for at least a decade and perhaps as far back as Windows NT. However for some reason the major cross-platform scripting languages including Perl and Python only ever output various 8-bit encodings, requiring much trouble to work around. Perl gives a "wide character in print" warning, Pythong gives a charmap error and quits. Why on earth after all these years do they not just simply call the Win32 -W APIs that output UTF-16 Unicode instead of forcing everything through the ANSI/codepage bottleneck? Is it just that cross-platform performance is low priority? Is it that the languages use UTF-8 internally and find it too much bother to output UTF-16? Or are the -W APIs inherently broken to such a degree that they can't be used as-is?

• OpenNETCF.Net.Ftp Behaving Flaky

  - by gnomixa

  I tried posting on their boards (authors of this library), however it literally takes months for them to reply when it comes to the free software (can't blame them). But anyways I have found that this library is behaving weirdly - for instance, a major problem with my application is when someone is trying to sign in (through FTP), they provide a correct login and mistype the password, no reply is received from FTP server. I tried doing the same from command window just to verify that it's not the FTP server's fault; and FTP commands were received instantaneously. It almost looks as though this library eats the commands. The same actions often times will yield different results. Can anyone recommend a stable, reliable library to use with Compact framework? Or shed some light on this issue...?

• Why does my report recalculate totals when I scroll in Access '07?

  - by andrewb

  Whenever I make a report in Access '07 and include some sort of total (whether counting or summing values), when I'm viewing the preview and scroll, the total recalculate. This is really annoying as Access takes a while (several tenths of a second) to do this, and while it does that the totals go blank. I've looked for a solution online, but I can't find this issue described anywhere. How can I stop the totals from recalculating when I scroll? I'm hoping for a simple solution that would solve this for all reports, or perhaps a simple property tweak on each report. I don't want to have to add code for every single report! I should describe the report layouts I'm using - they contain rows of data all on one page, and at times I group the rows. The number of rows aren't major, maybe around 50 a time or so.

• Return specific HREF attribute using Xpath query

  - by Michael Pasqualone

  Having a major brain freeze, I have the following chunk of code: // Get web address $domQuery = query_HtmlDocument($html, '//a[@class="productLink"]'); foreach($domQuery as $rtn) { $web = $rtn->getAttribute('href'); } Which obviously gets the entire href attribute, however I only want 1 specific attribute within the href. I.e. If the href is: /website/product1234.do?code=1234&version=1.3&somethingelse=blaah I only want to return the variable for "version", so wish to only return "1.3" in my example. What's most efficient way to do this?

• what kind of credentials/prerequisites do you need to be a professional penetration tester ?

  - by dfafa

  does it take more than knowing Bt4 ? are there any one that just runs a scanner and no real labor involved ? would you be expected to be able to code your own exploits without having to dl from milw0rm and discover entry into a system by yourself, in other words, do you have to think outside the box even when there's so many tools that makes the job a lot easier ? would you ever be expected to be able to write your own scanners, exploits and etc ? i am also curious how people are able to write long pages of hex address, that magically causes some type of memory overflow...how are people guessing at the hex values for game hacks for instance ? are certification important ? what about formal school education ? I am a CS major.

• ORMs and Constructors

  - by Harper Shelby

  I'm looking over .NET ORM implementations, and I have a major burning question - are there any .NET ORM implemenations that don't require public properties for every field in the database? When I see examples like this, a little bell goes off in my head. I firmly believe in encapsulation, and being forced to open the kimono of my objects just to make them work nicely with persistence frameworks gives me the heebie-jeebies. Is this sort of accessibility required in all ORMs out there? If not, please point me to examples of those that don't need it!

• Feature categories for a social network

  - by mafutrct

  Not sure if this question belongs on SO. Anyway, please let me try to clarify the issue. I'm currently planning a social program. It's basically a chat server with the major additional ability to play games. I'd like to create categories of features that are offered to users. My question is, are there any useful standard feature categories? Does not have to be specific to my case, I'm interested in the general case as well. Just to give you an idea of what I'm thinking: functional e.g. play games social e.g. chatting operational e.g. 24/7 service availability I'm entirely unsure if this is the right place to ask, if you know of any better site to ask please don't hesitate to add a comment.

• Is there a standard literal constant that I can use instead of "utf-8" in C# (.Net 3.5)?

  - by Hamish Grubijan

  Hi, I would like to find a better way to do this: XmlNode nodeXML = xmlDoc.AppendChild( xmlDoc.CreateXmlDeclaration( "1.0", "utf-8", String.Empty) ); I do not want to think about "utf-8" vs "UTF-8" vs "UTF8" vs "utf8" as I type code. I would like to make my code less prone to typos. I am sure that some standard library has declatred "utf-8" as a const / readonly string. How can I find it? Also, what about "1.0"? I am assuming that major XML versions have been enumerated somewhere as well. Thanks!

• Loading dictionary for input method suggestion list

  - by jpspringall

  Hi, For various reasons, i'm trying to write my own input keyboard. So far all is going well except that of creating the suggestions. I've found the latinIME algorithm, which is all good. However i'm having major difficulty working out how to load the dictionary in the first place. I've had a good look round the net, and found various suggestions, but no definitive answers, and i cant seem to get any of them to work. If anyone has any suggestions on how best to do it, or even better some sample code, that would be brilliant. Many Thanks James

• Why does java have an interpreter? and not a compiler?

  - by Galaxin

  Iam a newbie to java and was wondering why java have a interpreter and not a compiler? While shifting from c++ to java we come across the differences between these two Compilation process being one of them. 1.A major difference between a compiler and interpreter is that compiler compiles the whole code at once and displays all the errors at a time whereas an interpreter interprets line by line. 2.Also a compiler takes a less time to compile a code when compared to an interpreter. When java was developed for more advanced and easy features and implementations why has it been restricted to a interpreter based on above facts? Is there any special reason why this is so? If yes what is it?

• Having to keep on restarting the Application Pool?

  - by smclintock

  One of our major websites (built on PHP, MSSQL, IIS7) has started to become unresponsive every few hours and I'm having to log on to the server and restart the application pool. The rest of the websites on the server are fine, so I figure it may be due to a code problem? Whilst I look over all the code, specifically the database connections, would anyone have any advice on how I could better track this down to what is actually causing it to become unresponsive? By "unresponsive" I mean when you enter the URL it doesn't resolve and times out. Thanks for any help, Steven.

• Stopping pirates

  - by Pirate for Profit

  Okay, what do I do to stop pirates? Obviously a callhome to internet service. We are considering making some major aspects be dependent on a web service of some sort. Memory offsets and cracking. If I like rand randomly to allocate empty memory on the heap, would this throw off the crackers? I hacked some memory shit for EverQuest back in the dizzay but don't really know much about this. Registry on windows, etc., I know theres ways to identify the computer. That's easily spoofed with hex editor, but if I jumble up the strings in the program would that help? I need to know that + real ideas. I want the serials of their sound cards. Any other ideas?

• MSSql Query solution cum Suggestion Required

  - by Nirmal

  Hello All... I have a following scenario in my MSSql 2005 database. zipcodes table has following fields and value (just a sample): zipcode latitude longitude ------- -------- --------- 65201 123.456 456.789 65203 126.546 444.444 and "place" table has following fields and value : id name zip latitude longitude -- ---- --- -------- --------- 1 abc 65201 NULL NULL 2 def 65202 NULL NULL 3 ghi 65203 NULL NULL 4 jkl 65204 NULL NULL Now, my requirement is like I want to compare my zip codes of "place" table and update the available latitude and longitude fields from "zipcode" table. And there are some of the zipcodes which has no entry in "zipcode" table, so that should remain null. And the major issue is like I have more then 50,00,000 records in my db. So, query should support this feature. I have tried some of the solutions but unfortunately not getting proper output. Any help would be appreciated...

• Website with Microsites & Blog - recommendations

  - by pingu

  Hi guys, I'm in the process of scoping a solution for an events organisation. Their main website features information about them and blog entries etc, but they hold major events which require microsites (domain.com/event). The microsites all have a different look-and-feel, different nav structure, and custom content-managed components. The one thing that's common across everything is the blog - it will have a category for each event under which users can post. The main site will display all blog posts, but the microsites will only display posts for their category. How would you guys implement this? The solution needs to be PHP, and my initial thought was CodeIgniter but if possible I'd like to avoid building the blog functionality - so I guess I could integrate it with EE or Wordpress. If anyone has any other suggestions they would be most appreciated.

• What are some best practices for making sure your .NET code will scale well?

  - by billmaya

  Last week I interviewed for a position at a TripleA MMORPG game company here in NE. I didn't get the job but one of the areas that came up during the interview was the about the scalability of the code that you write and how it should be considered early on in the design of your architecture and classes. Sadly to say I've never thought very much about the scalability of the .NET code that I've written (I work with single user desktop and mobile applications and our major concerns are usually with device memory and rates of data transmission). I'm interested in learning more about writing code that scales up well so it can handle a wide range of remote users in a client server environment, specifically MMORPGs. Are there any books, web sites, best practices, etc. that could get me started researching this topic?

• capturing click events on web-browser scrollbars

  - by The Code Pimp

  Hi, is it possible to capture a click event on a scrollbar? I have some code where i am observing the click and mousedown events on the document. However, it seems that when I click on the scrollbar, the event is not captured. This leads me to believe that the scrollbars aren't really part of the document. (Assumption :-)) Is this a correct assumption? What is the right way to do this so that the behaviour is consistent across all major browsers? sample code document.observe('click', function(evt){ //do something //blah blah blah }); Thanks

  Can anyone help me with this major issue I have. I have downloaded my Drupal 7 site running fine on current server, but I cant run it on localhost or on the new server where I am trying to move it... It just gives me the "White Screen of Death"... and after commenting "set_error_handler" in boostrap.inc, I find out that the errors are all related to "public://" wrapper. This is how all the errors look like: Warning: is_dir() [function.is-dir]: Unable to find the wrapper "public" - did you forget to enable it when you configured PHP All these errors are coming from the following file: /includes/file.inc
