• Decision for Unchecked Exceptions in Scala

  - by Jatin

  As a java programmer, I have always been critical of Unchecked Exceptions. Mostly programmers use it as an en-route to coding easiness only to create trouble later. Also the programs (though untidy) with checked exceptions are much robust compared to unchecked counterparts. Surprisingly in Scala, there is nothing called Checked Exceptions. All the Java checked and unchecked are unchecked in Scala. What is the motivation behind this decision? For me it opens wide range of problems when using any external code. And if by chance the documentation is poor, it results in KILL.

• How do I get my Broadcom BCM4313 working correctly?

  - by Ataraxio Panzetta

  I've installed ubuntu on a Asus 1015 netbook. Everything worked out of the box except for the Wireless adapter, which i had to install with the Additional Drivers application. It apparently installed fine and connects to our wireless network, but it only works at a "funny" speed range that goes from 367Bytes to a peak of 3Kb in its best moments. I know for sure the problem is neither the network nor the hardware. Network speeds are normal under windows on this laptop and in other computers with ubuntu aswell. lspci says the card is a BCM4313 model, but the Addittional Drivers Manager says these packecege contains Broadcom 802.11 Linux STA wireless driverfor use with Broadcom's BCM4311-, BCM4312-, BCM4321-, and BCM4322 based hardware seems like it installed the wrong driver... Is there anything I can do? I'm not concerned about compiling the driver or stuff like that, but I'm not sure on where to start... any help or guidance will be very, very appreciated.

• Channelling an explosion along a narrow passage

  - by finnw

  I am simulating explosions in a 2D maze game. If an explosion occurs in an open area, it covers a circular region (this is the easy bit.) However if an explosion occurs in a narrow passage (i.e narrower than the blast range) then it should be "compressed", so that it goes further and also it should go around corners. Ultimately, unless it is completely boxed-in, then it should cover a constant number of pixels, spreading in whatever direction is necessary to reach this total area. I have tried using a shortest-path algorithm to pick the nearest N pixels to the origin avoiding walls, but the effect is exaggerated - the blast travels around corners too easily, making U-turns even when there is a clear path in another direction. I don't know whether this is realistic or not but it is counter-intuitive to players who assume that they can hide around a corner and the blast will take the path of least resistance in a different direction. Is there a well-known (and fast) algorithm for this?

• Trying to make a universe [on hold]

  - by caters

  I am wanting to program a universe so that it starts with a big bang and atoms form and then molecules form and stars start to form and planets start to form and then moons around those planets. I have a few questions. If 400 IPMUs(In Program Mass Units) = 1 solar mass than how would I calculate the number of IPMUs for a spectral class of star given the range of solar masses for a main sequence star in that spectral class? How can I have planets not look like stars? Since whether it is a subdwarf, main sequence star, subgiant, giant, bright giant, supergiant, or hypergiant is mainly dependent on the radius and luminosity how can I have the radius and luminosity independent of the mass?

• International TLD's vs. duplicate content

  - by Litso

  Hey all, I currently work at a pretty big website that has visitors from around the globe. My job is to help out on the SEO, and one thing we've been discussing lately is the use of international TLD's. The ones we use range between: (partly) translated websites like .es and .de that serve most of the content in the country's language non-translated (english) websites for non-english languages (due to a lack of translations) like .ro and .cz english websites for english speaking countries with localized TLD's (.co.nz, .co.uk) On one hand I really have the feeling this is causing a lot of duplicate content, especially for the last two categories of TLD's. On the other hand though it seems a lot like country-specific TLD's tend to score a lot better in that country's Google. Would it be advisable to keep on using these domains, or should we canonicalize them all to the .com version?

• C programming in 2011

  - by Duncan Bayne

  Many moons ago I cut C code for a living, primarily while maintaining a POP3 server that supported a wide range of OSs (Linux, *BSD, HPUX, VMS ...). I'm planning to polish the rust off my C skills and learn a bit about language implementation by coding a simple FORTH in C. But I'm wondering how (or whether?) have things changed in the C world since 2000. When I think C, I think ... comp.lang.c ANSI C wherever possible (but C89 as C99 isn't that widely supported) gcc -Wall -ansi -pedantic in lieu of static analysis tools Emacs Ctags Autoconf + make (and see point 2 for VMS, HP-UX etc. goodness) Can anyone who's been writing in C for the past eleven years let me know what (if anything ;-) ) has changed over the years? (In other news, holy crap, I've been doing this for more than a decade).

• How do I find which isometric tiles are inside the cameras current view?

  - by Steve

  I'm putting together an isometric engine and need to cull the tiles that aren't in the camera's current view. My tile coordinates go from left to right on the X and top to bottom on the Y with (0,0) being the top left corner. If I have access to say the top left, top right, bottom left and bottom right corner coordinates, is there a formula or something I could use to determine which tiles fall in range? This is a screenshot of the layout of the tiles for reference. If there isn't one, or there's a better way to determine which tiles are on screen and which to cull, I'm all ears and am grateful for any ideas. I've got a few other methods I may be able to try such as checking the position of the tile against a rectangle. I pretty much just need something quick. Thanks for giving this a read =)

• Iterating selected rows in an ADF Faces table

  - by Frank Nimphius

  In OTN Harvest May 2012; http://www.oracle.com/technetwork/developer-tools/adf/learnmore/may2012-otn-harvest-1652358.pdf I wrote about "Common mistake when iterating <af:table> rows". In this entry I showed code to access the row associated with a selected table row from the binding layer to avoid the problem of having to programmatically change the selected table row. As it turns out, my solution only worked fro selected table rows that are in the current iterator query range. So here's a solution that works for all ranges public String onButtonPress() { RowKeySet rks = table.getSelectedRowKeys(); Iterator it = rks.iterator(); while (it.hasNext()) { List selectedRowKeyPath = (List)it.next(); //table is the JSF component reference created using the table's binding //property Row row = ((JUCtrlHierNodeBinding)table.getRowData(selectedRowKeyPath)).getRow(); System.out.println("Print Test: " + row.getAttribute(1)); } return null; }

• 55 and counting: ADF and Forms sessions at Oracle World

  - by Grant Ronald

  There is a phenomenal agenda of Forms, ADF and JDeveloper running at Oracle World this year.  So far, I can see about 55 sessions which are directly related to my product areas (Forms, JDeveloper and Oracle ADF).  These range from high-level strategic keynotes, to deep dives and hands on sessions from some of the best known names in ADF and Forms.  As we get nearer the kick off date I'm going to call out a number of these sessions but if you are considering whether OracleWorld is a good way of spending your training dollars my answer would be an emphatic YES!

• How much to pay for artwork in an indie game?

  - by f20k

  I am an indie developer and I need some detailed artwork. How much is reasonable to pay an artist for say 20 character designs? I know it depends on the artist's skills, etc, but I am wondering what to expect so that I can budget it. Edit: Let's say cartoon-ish art (Example - not necessarily in that level of detail but that kind of cartoony-art style). No 3-d modelling - The art will be used as still images in game and for promotional reasons. I'd provide a base sprite design for them to expand on and detail. Also, some numbers would be nice - I like numbers. Even a range is helpful. Like: expect to spend $x2 ~ $x1 for top-notch and $y2 ~ $y1 for decent quality. I understand I can ask at some indie-help site but, if an artist says something like $1000 for 20 designs, I wouldn't have any idea if it's reasonable / good deal / bad idea etc.

• Prevent gnome-shell's dash from listing Recent Items

  - by Vivek

  I am using gnome-shell in Ubuntu 11.10. I am getting annoyed when dash search lists Recent Items. I have tried many ways to prevent it like Deleting activity.sqlite and activity.sqlite-journal files under ~/.local/share/zeitgeist Adding all the possible entries in Activity Log Manager to prevent application logging Specifying time range in Activity Log Manager to forget my activities. But none of the methods are working. The recent items list is still populated. Is there any way to tell dash not to list Recent Items while searching, other than the above methods? Or is there any way to delete the recent items list?

• Efficient way to calculate "vision cones" on 2D tile map?

  - by OverMachoGrande

  I'm trying to calculate which tiles a particular unit can "see" if facing a certain direction on a tile map (within a certain range and angle of facing). The easiest way would be to draw a certain number of tiles outward and raycast to each tile. However, I'm hoping for something slightly more efficient. A picture says a thousand words: The red dot is the unit (who's facing upwards). My goal is to calculate the yellow tiles. The green blocks are walls (walls are between tiles, and it's easy to check if you can pass between two tiles). The blue line represents something like the "raycasting" method I was talking about, but I'd rather not have to do this. EDIT: Units can only be facing north/south/east/west (0, 90, 180, or 270 degrees) and FoV is always 90 degrees. Should simplify some calculations. I'm thinking there's some sort of recursive-ish/stack-based/queue-based algorithm, but I can't quite figure it out. Thanks!

• How to change the IP address on my Ubuntu virtual NIC

  - by DextrousDave

  I have a physical windows system, on which I run Vmware Workstation. Now on VMware I run Ubuntu 12.10. I am running a webserver on Ubuntu via LAMP, inside VMware. Problem: Now my local IP address for my virtual NIC (the one Ubuntu is using) has an address of 192.168.159.7, and my home router only issues IP addresses of the range 10.0.0.x. So if I want to port forward to the virtual NIC, which has a 192.168 address, I cannot, so my LAMP webserver cannot be accessed externally since the router does not know to send the packets on port 80 to the virtual NIC... How do I fix that? The only way I guess is to assign a 10.0.0.x ip address to the virtual NIC?? But how do I do that? I tried to do it on the host Windows machine with 'Get my IP address automatically' but it issues a 192.168 address every time... Thank you
