  • How successful is GPL in reaching its goals?

    - by StasM
    There are, broadly, two types of FOSS licenses when it relates to commercial usage of the code - let's say the GPL-type and the BSD-type. The first is, broadly, restrictive about commercial usage (by usage I also mean modification and redistribution, as well as creating derived works, etc.) of the code under the license, and the second is much more permissive. As I understand, the idea behind GPL-type licenses is to encourage people to abandon the proprietary software model and instead convert to the FOSS code, and the license is the instrument to entice them to do so - i.e. "you can use this nice software, but only if you agree to come to our camp and play by our rules". What I want to ask is - was this strategy successful so far? I.e. are there any major achievements in the form of some big project going from closed to open because of GPL or some software being developed in the open only because GPL made it so? How big is the impact of this strategy - compared, say, to the world where everybody would have BSD-type licenses or release all open-source code under public domain? Note that I am not asking if FOSS model is successful - this is beyond question. What I am asking is if the specific way of enticing people to convert from proprietary to FOSS used by GPL-type and not used by BSD-type licenses was successful. I also don't ask about the merits of GPL itself as the license - just about the fact of its effectiveness.

  • How to play simultaneous multiply audio sources in Silverlight

    - by Shurup
    I want to play simultaneous multiply audio sources in Silverlight. So I've created a prototype in Silverlight 4 that should play a two mp3 files containing the same ticks sound with an intervall 1 second. So these files must be sounded as one sound if they will be played together with any whole second offsets (0 and 1, 0 and 2, 1 and 1 seconds, etc.) I my prototype I use two MediaElement (me and me2) objects. DateTime startTime; private void Play_Clicked(object sender, RoutedEventArgs e) { me.SetSource(new FileStream(file1), FileMode.Open))); me2.SetSource(new FileStream(file2), FileMode.Open))); var timer = new DispatcherTimer { Interval = TimeSpan.FromMilliseconds(1) }; timer.Tick += RefreshData; timer.Start(); } First file should be played at 00:00 sec. and the second in 00:02 second. void RefreshData(object sender, EventArgs e) { if(me.CurrentState != MediaElementState.Playing) { startTime = DateTime.Now; me.Play(); return; } var elapsed = DateTime.Now - startTime; if(me2.CurrentState != MediaElementState.Playing && elapsed >= TimeSpan.FromSeconds(2)) { me2.Play(); ((DispatcherTimer)sender).Stop(); } } The tracks played every time different and not simultaneous as they should (as one sound).

  • What languages should a microISV use to write commercial software?

    - by Wal
    I've been writing software in Java for many years now, but it was always for internal applications that would be deployed to a server. I'd like to get into writing desktop applications now but I don't know where to start. I've written a few Java/Swing applications but again they were for internal use. My understanding is that Java and other semi-compiled and interpreted languages are too easy to reverse engineer, making them unsuitable for commercial software. I am aware that there are compilers for Java and some other interpreted language, but I've also heard that they are pricey and/or unreliable. Assuming I start a microISV and wish to develop and sell applications to a broad audience, what's my best bet? I would prefer something that can be written close to once, and compiled for different operating systems but I am not opposed to .NET and a Windows-only audience if other languages would compromise the experience (installation ease & user experience) in Windows. My only issue there is that I don't have a large starting budget and paying out the wazoo for the required development tools is not really in the cards.

  • Have any software engineers gotten math degrees later in their careers?

    - by vin
    I have a bachelors in computer science and worked the last 12 years as a software engineer. I'm bored with doing general development work, so I want to specialize. I'm thinking about getting a master's degree in math so I can build math models and write algorithms to implement them. I'm unsure what type of work I'd do (financial, gaming, graphics, science, research, etc) but I'm open minded. I would need to refresh my undergrad math skills (which are old and faded), but I loved algebra and calculus. I've been working with couple statisticians so I've been finding myself more interested in statistics. Since I'm a parent supporting a household, I would have to continue working while studying. Have any software engineers taken this route? (Specifically, going from BS in comp sci to MS in math.) If so, what advice do you have for coursework, financing, and getting a job that combines programming with advanced math? How abundant are these kinds of jobs? I'm not sure where one starts. Also, how do you hop from a BS to an MS in a different subject?

  • What's the canonical way to acknowledge many FOSS sources in a single project?

    - by boost
    I have a project which uses a large number of LGPL, Artistic and other open-source licensed libraries. What's the canonical (i.e. the "standard") way of acknowledging multiple sources in a single project download? Also, some of the sources I've used are from sites where using the code is okay, but publishing the source isn't. What's the usual manner of attribution in that case, and the usual manner of making the source available in an open-source project?

  • many-to-many-to-many, incl alignment of data from diff sources

    - by JefeCoon
    Re-factoring dbase to support many:many:many. At the second and third levels we need to preserve end-user 'mapping' or aligning of data from different sources, e.g. Order 17 FirstpartyOrderID => aha LineItem_for_BigShinyThingy => AA-1 # maps to 77-a LineItem_for_BigShinyThingy => AA-2 # maps to 77-b, 77-c LineItem_for_LittleWidget => AA-x # maps to 77-zulu, 77-alpha, 99-foxtrot LineItem_for_LittleWidget => AA-y # maps to 77-zulu, 99-foxtrot LineItem_for_LittleWidget => AA-z # maps to 77-alpha ThirdpartyOrderID => foo LineItem_for_BigShinyThingy => 77-a LineItem_for_BigShinyThingy => 77-b LineItem_for_BigShinyThingy => 77-c LineItem_for_LittleWidget => 77-zulu LineItem_for_LittleWidget => 77-alpha ThirdpartyOrderID => bar LineItem_for_LittleWidget => 99-foxtrot Each LineItem has daily datapoints reported from its own source (Firstparty|Thirdparty). In our UI & app we provide tools to align these, then we'd like to save them into the cleanest possible schema for querying, enabling us to diff the reported daily datapoints, and perform other daily calculations (which we'll store in the dbase also, fortunately that should be cake once we've nailed this). We need to map related [firstparty|thirdparty]line_items which have their own respective datapoints. We'll be using the association to pull each line_items collection of datapoints for summary and discrepancy calculations. I'm considering two options, std has_many,through x2 --or-- possibly (scary) ubermasterjoin table OptionA: order<<-->> order_join_table[id,order_id,firstparty_order_id,thirdparty_order_id] <<-->>line_item order_join_table[firstparty_order_id]-->raw_order[id] order_join_table[thirdparty_order_id]-->raw_order[id] raw_order-->raw_line_items[raw_order_id] line_item<<-->> line_item_join[id,LI_join_id,firstparty_LI,thirdparty_LI <<-->>raw_line_items line_item_join[firstparty_LI]-->raw_line_item[id] line_item_join[thirdparty_LI]-->raw_line_item[id] raw_line_item<<-->>datapoints = we rely upon join to store all mappings of first|third orders & line_items = keys to raw_* enable lookup of these order & line_item details = concerns about circular references and/or lack of correct mapping logic, e.g order--line_item--raw_line_items vs. order--raw_order--raw_line_items OptionB: order<<-->> join_master[id,order_id,FP_order_id,TP_order_id,FP_line_item_id,TP_line_item_id] join_master[FP_order_id & TP_order_id]-->raw_order[id] join_master[FP_line_item_id & TP_line_item_id]-->raw_line_item[id] = every combo of FP_line_item + TP_line_item writes a record into the join_master table = "theoretically" queries easy/fast/flexible/sexy At long last, my questions: a) any learnings from painful firsthand experience about how best to implement/tune/optimize many-to-many-to-many relationships b) in rails? c) any painful gotchas (circular references, slow queries, spaghetti-monsters) to watch out for? d) any joy & goodness in Rails3 that makes this magically easy & joyful? e) anyone written the "how to do many-to-many-to-many schema in Rails and make it fast & sexy?" tutorial that I somehow haven't found? If not, I'll follow up with our learnings in the hope it's helpful.. Thanks in advance- --Jeff

  • What development terms come from the construction industry?

    - by Renesis
    When talking with colleagues about software design and development principles, I've noticed one of the most common sources for analogies is the construction industry. It would be quite useful to have a list of what programming/development terms and concepts are borrowed from construction industry? (And please provide a description or experiences regarding that topic.) [Credit to Programming concepts taken from the arts and humanities for the idea]

  • Izenda Reports 6.3 Top 10 Features

    - by gt0084e1
    Izenda 6.3 Top 10 New Features and Capabilities 1. Izenda Maps Add-On The Izenda Maps add-on allows rapid visualization of geographic or geo-spacial data.  It is fully integrated with the the rest of Izenda report package and adds a Maps tab which allows users to add interactive maps to their reports. Contact your representative or [email protected] for limited time discounts. Izenda Maps even has rich drill-down capabilities that allow you to dive deeper with a simple hover (also requires dashboards). 2. Streamlined Pie Charts with "Other" Slices The advanced properties of the Pie Chart now allows you to combine the smaller slices into a single "Other" slice. This reduces the visual complexity without throwing off the scale of the chart. Compare the difference below. 3. Combined Bar + Line Charts The Bar chart now allows dual visualization of multiple metrics simultaneously by adding a line for secondary data. Enabled via AdHocSettings.AllowLineOnBar = true; 4. Stacked Bar Charts The stacked bar chart lets you see a breakdown of a measure based on categorical data.  It is enabled with the following code. AdHocSettings.AllowStackedBarChart = true; 5. Self-Joining Data Sources The self-join features allows for parent-child relationships to be accessed from the Data Sources tab. The same table can be used as a secondary child table within the Report Designer. 6. Report Design From Dashboard View Dashboards now sport both view and design icons to allow quick access to both. 7. Field Arithmetic on Dates Differences between dates can now be used as measures with the arithmetic feature. 8. Simplified Multi-Tenancy Integrating with multi-tenant systems is now easier than ever. The following APIs have been added to facilitate common scenarios. AdHocSettings.CurrentUserTenantId = value; AdHocSettings.SchedulerTenantID = value; AdHocSettings.SchedulerTenantField = "AccountID"; 9. Support For SQL 2008 R2 and SQL Azure Izenda now supports the latest version of Microsoft's database as well as the SQL Azure service. 10. Enhanced Performance and Compatibility for Stored Procedures Izenda now supports more stored procedures than ever and runs them faster too.

  • Ideas for a rudimentary software licensing implementation

    - by Ross
    I'm trying to decide how to implement a very basic licensing solution for some software I wrote. The software will run on my (hypothetical) clients' machines, with the idea being that the software will immediately quit (with a friendly message) if the client is running it on greater-than-n machines (n being the number of licenses they have purchased). Additionally, the clients are non-tech-savvy to the point where "basic" is good enough. Here is my current design, but given that I have little to no experience in the topic, I wanted to ask SO before I started any development on it: A remote server hosts a MySQL database with a table containing two columns: client-key and license quantity The client-side application connects to the MySQL database on startup, offering it's client-key that I've put into a properties file packaged into the distribution (I would create a new distribution for each new client) Chances are, I'll need a second table to store validation history, so that with some short logic, the software can decide if it can be run on a given machine (maybe a sliding window of n machines using the software per 24 hours) If the software cannot establish a connection to the MySQL database, or decides that it's over the n allowed machines per day, it closes The connection info for the remote server hosting the MySQL database should be hard-coded into the app? (That sounds like a bad idea, but otherwise they could point it to some other always-validates-to-success server) I think that about covers my initial design. The intent being that while it certainly isn't full-proof, I think I've made it at least somewhat difficult to create an easily-sharable cracking solution. Also, I can easily adjust the license amount for a given client/key pair. I gotta figure this has been done a million times before, so tell me about a better solution that's just as simple to implement and provides the same (low) amount of security. In the event that external libraries are used, I prefer Java, as that's what the software has been written in.

  • help on developing enterprise level software solutions

    - by wefwgeweg
    there is a specific niche which I would like to target by providing a complete enterprise level software solution.... the problem is, where do i begin ? meaning, i come from writing just desktop software on VB/ASP .net/PHP/mysql and suddenly unfamiliar terms popup like Oracle, SAP Business Information Warehouse, J2EE.... obviously, something is pointing towards Java, is it common for software suites, or solutions to be developed 100% on Java technology and standards? Are there any other platform to build enterprise level software on ? i am still lacking understanding what exactly is "Enterprise level" ? what is sufficient condition to call a software that sells for $199 and then suddenly it's $19,999 for "enterprise" package. I dont understand why there is such a huge discrepancy between "standard" and "enterprise" versions of software. Is it just attempting to bag large corporations on a spending spree ? so why does one choose to develop so called "enterprise" softwares ? is it because of the large inflated price tag you can justify with ? i would also like some more enterpreneural resources on starting your own enterprise software company in a niche.... Thank you for reading, i am still trying to find the right questions.
