• Which forum software has the most advanced community/GetSatisfaction type features?

  - by Gaia

  I need to assemble a GetSatisfaction/Lithium/Jive type support forum/community. The first is not available in the desired language and the last two are priced for the enterprise market. I did research some other options (open source or SaaS) but they all seem to be either: kind of dead (open source options) too focused in gathering ideas/feedback (uservoice) strictly support without the community/voting features (zendesk) I need an open forum (people powered support/UGC with community/voting features). Therefore I will have to do some of the work on my own. I want to piece things (plugins/mods/etc) on top of a standard forum platform to give it the features I need. For this purpose, I want to use a mature product with widespread userbase, active community and lots of plugin options. I believe most will agree that my options therefore are: vBulletin phpBB SMF Here are the questions: Which one of the three above offers the easier path towards the desired goal? Which one of the three above has the most advanced features related to the desired goal? Of course I dont expect anyone to know these answers cut and dry. I am hoping to hear some experiences and see some examples. Also, it would be great if both those questions had the same answer, but I am not going to get my hopes up... PS: I wish I could add the tags "phpbb" and "smf" ;)

• wget has a 4 second delay

• How do I keep controversy in check?

  - by Aaron Digulla

  This is probably OT but it's less OT here than on any other SO site, so please bear with me. I'm working on a new project votEm. The goal is to give independent candidates a platform to introduce themselves to get elected for a political office. My main reason is that today, it's too expensive to run for an office. Some politicians in the US spend as much as 30 million dollars (!) for a single campaign. That money is better spent elsewhere. In a similar fashion, people who want to change countries like Egypt, could use such a platform to present themselves. Now I expect a lot of emotions and pressure on my site. People with a lot of money (and a lot to lose) will try to game it (political parties, secret services of ... errr ... "not 100% democratic countries", big companies, ...) To avoid as many mistakes as possible, I need a list of resources, ideas and tips how to keep such a site out of too much trouble. PS: I'd make this CW but the option seems to be gone...

• What are the requirements to test a website using jquery.get() ? [migrated]

  - by Frankie

  I am working on a simple website. It has to search quite a few text files in different sub-folders. The rest of the page uses jquery, so I would like to use it for this also. The function I am looking at is .get() for downloading the files. So my main question is, can I test this on my local computer (Ubuntu Linux) or do I have to have it uploaded to a server? Also, if there's a better way to go about this, that would be nice to know. However, I'm more worried about getting it working. Thanks, Frankie PS: Heres the JS/jQuery code for downloading the files to an array. g_lists = new Array(); $(":checkbox").each(function(i){ if ($(this).attr("name") != "0") { var path = "../" + $(this).attr("name") + ".txt"; $("#bot").append("<br />" + path); // debug $.get(path, function(data){ g_lists[i] = data; $("#bot").html(data); }); } else { g_lists[i] = ""; } }); Edit: Just a note about the path variable. I think it's correct, but I'm not 100% sure. I'm new to web development. Here's some examples it produces and the directory tree of the site. Maybe it will help, can't hurt. . +-- include ¦   +-- jquery.js ¦   +-- load.js +-- index.xhtml +-- style.css +-- txt    +-- Scripting_Tools    +-- Editors.txt    +-- Other.txt Examples of path: ../txt/Scripting_Tools/Editors.txt ../txt/Scripting_Tools/Other.txt Well I'm a new user, so I can't "answer" my own question, so I'll just post it here: After asking for help on a IRC chat channel specific to jQuery, I was told I could use this on a local host. To do this I installed Apache web server, and copied my site into it's directory. More information on setting it up can be found here: http://www.howtoforge.com/ubuntu_debian_lamp_server Then to run the site I navigated my browser to "localhost" and everything works.

• ADF Faces Skin Editor - How to Work with It

  - by Shay Shmeltzer

  The ODTUG Kscop11 conference was a great success with lots of sessions about FMW running in a special track. I did several sessions and labs in the conference, and I thought it might be a good idea to at least give you a taste of what you might have missed. So here is most of what I demoed in my ADF Faces Skinning session (not all though - that session was 60 minutes long, and while everyone did end up going out of the building in the middle because of a fire drill for about 5 minutes, there was other things covered in the session as well). In the demo here you'll see how to generate new images and default color scheme, how to identify a component class with Firebug, how to skin a component, how to identify the global selector of a property, how to change fonts and how to change strings. By the way, for more on ADF Skinning you should also listen to the ADF Insider seminar that Frank Nimphius recorded on skinning, it will give you better understanding of the overall skinning process. P.S. in the demo I add an entry to the web.xml file which prevent ADF Faces from compressing the HTML that is generated. The entry is for org.apache.myfaces.trinidad.DISABLE_CONTENT_COMPRESSION  and I set it to true. This is very useful when you work on creating the skin, but don't forget to un-set it before you go production.

• XPath & XML EDI B2B

  - by PearlFactory

  GoodToGo :) Best XML Editor is Altova XMLSpy 2011 http://www.torrenthound.com/hash/bfdbf55baa4ca6f8e93464c9a42cbd66450bb950/torrent-info/Altova-XMLSpy-Enterprise-Edition-SP1-2011-v13-0-1-0-h33t-com-Full For whatever reason Piratebay has trojans and other nasties..Search in torrent.eu for Altova XMLSpy Enterprise Edition SP1 2011 v13.0.1.0 Also if you like the product purchase it in a Commercial Enviroment Any well structured/complex XML can be parsed @ the speed of light using XPATH querys and not the C# objects XPathNodeIterator and others etc ....Never do loops  or Genirics or whatever highlevel language technology. Use the power of XPATH i.e Will use a Simple (Do while) as an example. We could have many different techs all achieveing the same result Instead of   xmlNI2 = xmlNav.Select("/p:BookShop")         if (xmlNI2.Count != 0)            {                                 while ((xmlNI2.MoveNext()))              string aNode =xmlNI2.SelectSingleNode('Book', nsmgr); if (aNode =="The Book I am after")       Console.WriteLine("Found My Book);   This lengthy cumbersome task can be achieved with a simple XPATH query Console.WriteLine((xmlNavg.SelectSingleNode("/p:BookShop/Book[.='The Book I am aFter ']", nsmgr)).Value.ToString()); Use the power of the parser and eliminate the middleman C#/MSIL/JIT etc etc Get Started Fast and use the parser as Outlined 1) Open XML and goto Grid Mode 2) Select XPATH tab on the bottom viewer/window as shown  From here you get intellisense and can quickly learn how to navigate/find the data using XPATH A key component to Navigation with XPATH is to use the "../ " command . This basically says from where I am now go up 1 level . With Xpath all commands are cumalative. i.e you can search for a book title @ the 2nd level of the XML and from there traverse 15 layers to paragraphs or words on a page with expression validation occuring throughout this process etc  (So in essence you may have arrived @ a node within the XML and have met 15 conditions along the way ) Given 1-2 days with XmlSpy and XPATH you unlock a technology that is super fast and simple to use. XML is a core component to what lays under the hood of so many techs. So it is no wonder that you want to be able to goto  the atomic level to achieve the result you want Justin P.S For a long time I saw XML as slow and a bit boring but now converted

• How to disable an "always there" program if it isn't in the processes list?

  - by rumtscho

  I have Crashplan and it is constantly running in the background and making backups every 15 minutes. It caused some problems with the backup target folders, so I want it to be inactive while I am making changes to these folders. I started the application itself, but could not find some kind of "Pause" button. So I decided to just stop its process. I first tried the lazy way - the system monitor in the Gnome panel has a "Processes" tab - but didn't find it listed there. Then I did a sudo ps -A and read through the whole list. I don't recognize everything on the list (many process names are self-explaining, like evolution-alarm, but I don't recognize others like phy0) but there was nothing which sounded even remotely like crashplan. But I know that there must have been a process belonging to Crashplan running at this time, because the main Crashplan window was open when I ran the command. Do you have any advice how to stop this thing from running? The best solution would involve temporary preventing it from loading on boot too, since I may need to reboot while doing the maintenance there.

• Passing Parameters to an ADF Page through the URL - Part 2.

  - by shay.shmeltzer

  I showed before how to pass a parameter on the URL when invoking a taskflow (where the taskflow starts with a method call and then a page). However in some simpler scenarios you don't actually need a full blown taskflow. Instead you can use page level parameters defined for your page in the adfc-config.xml file. So below is a demo of this technique. I'm also taking advantage of this video to show the concept of a view object level service method and how to invoke it from your page. P.S. You might wonder - why not just reference #{param.amount} as the value set for the method parameter? Why do I need to copy it into a viewScope parameter? The advantage of placing the value in the viewScope is that it is available even when the page went through several sumbits. For example if you switch the "partialSumbit" property of the "Next" button to false in the above example - the minute that you press the button to go to the next department - the param.amount value is gone. However the ViewScope is still there as long as you stay on this page.

• What to do when 'dpkg --configure -a' fails with too many errors?

  - by rudivonstaden

  During an upgrade from lucid (10.04) to precise (12.04), the X session froze, and I have been trying to recover the upgrade to get a stable system. I have performed the following steps: Used ssh to log in to the stalled system over the network. Checked the contents of the /var/log/dist-upgrade directory. There was no activity on main.log, apt.log or term.log. top showed that process 'precise' was using about 3% CPU, but I could find no evidence that the upgrade process was still doing anything. 'dpkg' did not show up in top, but it came up with pgrep dpkg | xargs ps Killed the 'dpkg' and 'precise' processes Tried to recover the upgrade by running sudo fuser -vki /var/lib/dpkg/lock;sudo dpkg --configure -a. This was partially successful (some packages were configured), but failed with the message Processing was halted because there were too many errors. I ran the same command a few times, and each time some packages were configured but others failed. Tried running sudo apt-get -f install. It fails with similar errors to dpkg. The current situation is that dpkg --configure -a and sudo apt-get -f install fails with two kinds of error: Dependency issues, e.g.: dpkg: dependency problems prevent configuration of cifs-utils: cifs-utils depends on samba-common; however: Package samba-common is not configured yet. dpkg: error processing cifs-utils (--configure): dependency problems - leaving unconfigured Resource conflict, e.g.: debconf: DbDriver "config": /var/cache/debconf/config.dat is locked by another process: Resource temporarily unavailable Additionally, it seems there's reference to potential boot problems, so I'm not keen to reboot without fixing the install first: dpkg: too many errors, stopping Processing triggers for initramfs-tools ... update-initramfs: Generating /boot/initrd.img-3.2.0-25-generic cryptsetup: WARNING: failed to detect canonical device of /dev/sda1 cryptsetup: WARNING: could not determine root device from /etc/fstab So my question is, how to get a working install when dpkg --configure -a fails?

• OS choice for functional developing

  - by Carsten König

  I'm mainly a .NET developer so I normaly use Windows/VisualStudio (that means: I'm spoiled) but I'm enjoying Haskell and other (mostly functional) languagues in my spare time. Now for Haskell the windows-support is ok (you can get the Haskell-Platform) but latley I tried to get a basic Clojure/Scheme environment set up and it's just a pain on windows. So I'm thinking about trying out another OS for better tooling and languague support. Of course that leaves me with MacOS or some Linux distribution. I never used MacOS before and of course Linux would be cheaper (free) and I don't think I can parallel-boot MacOS on your normal PC-Hardware (can you?). PLUS: I don't have a clue about the tools you can use on those (to me) forign OSs. To make it short: I want to explore more Haskell, Clojure, Scala, Scheme and of course need at least good tooling for JavaScript/HTML5/Css. Support for .NET/Mono/F# would be great but for this I will still have my Win7 boot. So I like to know: - what is your prefered OS, Distribution (is Ubuntu viable?) - what Editor/IDE are you using Thank you for your help! PS: I'm not sure if this is the right place for this question but I surely hope so - if not please let me know where I should move this to (StackOverflow don't seem to be the right place IMHO)

• Dynamic model interactions

  - by Richard

  I am just curious as to how in many games (namely games like arkham asylum/city, manhunt, hitman) do they make it so that your character can "grab" a character in front of you and do stuff to them. I know this may sound very confusing but for an example go to youtube and search "hitman executions", and the first video is an example of what i'm asking. Basically I'm wondering how they make your model dynamically interact with whatever other model you come across, so in hitman when you come up behind some one with the fibre wire you strangle the other character or if you have the anesthetic you come up behind some person and put your hand over there mouth while they struggle and slowly go to the floor where you lay them down. I am confused as to whether it was animated to use two models using specific bone/skeletal identifiers, if it is just two completely separate animations that are played at the correct time to make it look like they are actually interacting or something else all together. I am not an animator so i assume most of what i just said is not right but i hope that some one can understand what i mean and provide an answer. PS) I am a programmer and I am in the process of building a hitmanesque game, just because i love that style of game and I want to increase my skills on something fun, so if you do know what i'm talking about have some examples with involving both models and programming (i use c++ and mainly Ogre3D at the moment but i am getting into unity and XNA) i would greatly appreciate it. Thanks.

• Is realtime validation of username good or bad?

  - by iamserious

  I have a simple form for the user to sign up to my site; with email, username and password fields. We are now trying to implement an ajax validation so the user doesn't have to post the form to find out if the username is already taken. I can do this either on keyup event or on text blur event. My question is, which of these is really the best way to do? Keyup From the user POV, it would be good if the validation is done as and when they are typing, (on key up event) - of course, I am waiting for half a second to see if the user stops typing before firing off the request, and user can make any adjustments immediately. But this means I am sending way more requests than if I validated the username on Blur event. Blur The number of requests will be much lower when the validation is done on blur event, But this means the user has to actually go away from the textbox, look at the validation result, and if necessary go back to it to make any changes and repeat the whole process until he gets it right. I had a quick look at google, tumblr, twitter and no one actually does username validations on keyup events, (heck, tubmlr waits for the form to be posted) but I can swear I have seen keyup validations in a lot of places too. So, coming back to the question, will keyup validations be too many for server, is it an unnecessary overhead? or is it worth taking these hits to give user a better experience? ps: all my regex validations etc are already done on javascript and only when it passes all these other criteria does it send a request to server to check if a username already exists. (And the server is doing a select count(1) from user where username = '' - nothing substantial, but still enough to occupy some resource) pps: I'm on asp.net, MS SQL stack., if that matters.

• Dual boot on Hp Envy Ultrabook

  - by phodu_insaan

  I just bought a HP Envy ultrabook 1002TX. It comes with a Win7 Home basic and a 32GB SSD + 500GB HDD. I started to install ubuntu and in doing so went and deleted all the partitions on my HDD and recreated them the way I wanted. Then when I tried to install ubuntu it didn't recognize my HDD. To solve this i typed dmraid -E -r /dev/sdX where the 'X' was my SSD drive. After this ubuntu can install but windows for some reason does not install. Also the Intel Caching feature is lost and SSD is just sitting and doing nothing. I want to know how to solve this problem. Ideeally I would like to use the SSD for caching, either in windows or ubuntu. How do I get the SSD back to working as an Intel rapid cache? How do I get windows to install properly? It tell me that windows is unable to configure itself to my hardware, and my PC came with windows pre-installed so this is not possible. Sorry for the long question and thanks for your answers! PS: At one time when I booted I pressed Ctrl+i and went to the intel rapid cache menu. I think i screwed up something in here, because only after this the rapid cache stopped working, and each time I booted the PC thought the BIOS was my primary disk.

• Object construction design

  - by James

  I recently started to use c# to interface with a database, and there was one part of the process that appeared odd to me. When creating a SqlCommand, the method I was lead to took the form: SqlCommand myCommand = new SqlCommand("Command String", myConnection); Coming from a Java background, I was expecting something more similar to SqlCommand myCommand = myConnection.createCommand("Command String"); I am asking, in terms of design, what is the difference between the two? The phrase "single responsibility" has been used to suggest that a connection should not be responsible for creating SqlCommands, but I would also say that, in my mind, the difference between the two is partly a mental one of the difference between a connection executing a command and a command acting on a connection, the latter of which seems less like what I have been lead to believe OOP should be. There is also a part of me wondering if the two should be completely separate, and should only come together in some sort of connection.execute(command) method. Can anyone help clear up these differences? Are any of these methods "more correct" than the others from an OO point of view? (P.S. the fact that c# is used is completely irrelevant. It just highlighted to me that different approaches were used)

• How can I get cross-browser consistent behavior for TR heights within a table with a set height? [migrated]

  - by Dan

  I have an arbitrary number of tables with an arbitrary number of rows in each, and all tables are the same height. My initial approach was to just set the overall height of the table and hope the rows were smart enough to distribute themselves appropriately. That's not the case. I have 4 different behaviors going on with 4 browsers, but I need them to all render at the very least in a similar way. Safari & Chrome (WebKit): All rows are equal height, creating scroll bars as needed and fitting within table height. Firefox: All rows are the height necessary to fit their content, with the remaining rows overflowing out of the table. Additionally, If the content of the rows does not take up all of the height, only the part of the table with content in it takes the background (though it seems, through use of Firebug, that the actual table [and TR] extend to the bottom of the proper table height). IE: All rows are the height necessary to fit their content, with the remaining rows overflowing out of the table. Obviously this only includes one version of each browser and additional variation would likely appear with more being tested. Ideally, a solution where the browser renders TRs with less content smaller than those with larger content, while still using scrolling within the variable height TRs when the overall height of the table is not enough would be optimum. I could potentially see a solution to achieve that with JS, but can it be done with CSS? Or, if not, can the behavior that WebKit displays be made to work across the browsers? Thanks! PS: Example can be found here.

• Cannot Boot, How to recover

  - by Kendor

  Am running 11.10 64-bit with Gnome-shell. Something happened late Friday whereby my machine never gets to the login screen. I do get to an Ubuntu splash logo, after that I get a text screen that it hangs on. The screen is referring to issues with mounting various network resources, including VMWare and also some references to my NAS that are in fstab. If I hit "esc" I can get to the GRUB menu and into recovery console. If I try to do a file system check, I run into a similar error screen that I see when trying to boot normally. A possible clue here is that during my last good session I made some mods to the /etc/hosts file to reference another system which I'm connecting to with Synergy. I don't believe I have hardware issues as I'm able to boot properly with a Live USB and connect to my network/Internet. A few more tidbits. I have regular Dejadups backups on my NAS. I have a good Clonezilla whole drive image which is 4-6 weeks old.. My home is encrypted. I thought I'd try blowing away my hosts file via live USB, but when I mounted the hard drive everything was read-only and I couldn't figure out how to replace it. P.S. I logged in via CLI and modded the host file to remove the entry I'd made, to no avail. System continue to gets stuck on the following: CIFS VFS: default security mechanism requested. The default security mechanism will be upgraded from ntlm to ntlmv2 in kernel version 3.1s Would love some sober advice on how to attack this.

• PhysX Capsule Character Controller floating above ground

  - by Jannie

  I am using PhysX Version 3.0.2 in the simulation package I'm working on, and I've encountered some bizarre behavior with the capsule character controller. When I set the controller's height and radius to the appropriate values (r = 0.25, h = 1.86)it behaves correctly (moving along the ground, colliding with other objects, and so on) except that the capsule itself is floating above the ground. The actor will then bump his head when trying to get through a door, since the capsule is the correct height but also floating above the ground. This image should illustrate what I'm going on about: One can clearly see that the rest of the scene has their collision bodies wrapped correctly, it's just the capsule that's going wrong! The stop-gap I've implemented is creating a smaller capsule and giving it an offset, but I need to implement ray-picking for the controller next so the capsule has to surround the character model properly. Here's my character creation code (with height = 1.86f and radius = 0.25f): NxController* D3DPhysXManager::CreateCharacterController( std::string l_stdsControllerName, float l_fHeight, float l_fRadius, D3DXVECTOR3 l_v3Position ) { NxCapsuleControllerDesc l_CapsuleControllerDescription; l_CapsuleControllerDescription.height = l_fHeight; l_CapsuleControllerDescription.radius = l_fRadius; l_CapsuleControllerDescription.position.set( l_v3Position.x, l_v3Position.y, l_v3Position.z ); l_CapsuleControllerDescription.callback = &this->m_ControllerHitReport; NxController* l_pController = this->m_pControllerManager->createController( this->m_pScene, l_CapsuleControllerDescription ); this->m_pControllerMap.insert( l_ControllerValuePair( l_stdsControllerName, l_pController ) ); return l_pController; } Any help at all would be appreciated, I just can't figure this one out! P.S. I've found a couple of (rather old) threads describing the same issue, but it seems they couldn't find a solution either. Here are the links: http://forum-archive.developer.nvidia.com/index.php?showtopic=6409 http://forum-archive.developer.nvidia.com/index.php?showtopic=3272 http://www.ogre3d.org/addonforums/viewtopic.php?f=8&t=23003

• Combining pathfinding with global AI objectives

  - by V_Programmer

  I'm making a turn-based strategy game using Java and LibGDX. Now I want to code the AI. I haven't written the AI code yet. I've simply designed it. The AI will have two components, one focused in tactics and resource management (create troops, determine who have strategical advantage, detect important objectives, etc) and a individual component, focused in assign the work to each unit, examine its possibilites and move the unit. Now I'm facing an important problem. The map where the action take place is a grid-based map. Each terrain has different movement cost. I read about pathfinding and I think A* is a very good option to determine a good route between two points. However, imagine I have an unit with movement = 5 (i.e, it can move 5 tiles of movement cost = 1). My tactical AI has found an objective at a distance d = 20 tiles (Manhattan distance) from my unit. My problem is the following: the unit won't be able to reach the objective in one turn. So the AI will have to store a list of position and execute them in various turns. I don't know how to solve this. PS. In my unit code, I have a list called "selectionMarks" which stores all the possible places where the unit can go in this turn. This places are calculed recursively using a "getSelectionMarks" function. Any help is appreciated :D

• Facebook shared links not opening (Redirecting correctly) [on hold]

  - by Hammad

  I have been in a problem and after hours of searching find nothing useful to counter it. I have a website, and that website has RSS feed attached to facebook page. As I post the content to website it also appears on facebook page. But I have people complaining on my page that my posts don't open when they click the link to read the details. Since I am a Chrome user and didn't notice this happening for months. But as I checked it through firefox and Internet Explorer, I found the links shared actually don't open with these browswers. They only work in Chrome, means they are properly redirected in chrome browser and not in firefox and IE. Whenever I click on links of posts on my page through IE or firefox the url does not simply redirect to my website and I get to see nothing as if I am not connecting to Internet. When examining URL I see this: http://www.facebook.com/l.php?u=http%3A%2F%2Fbit.ly%2F112NVO9&h=EAQHDgTUv&s=1 Which shows that facebook is not redirecting the links properly. Moreover I also use link shortening service bit.ly to shorten my shared links. I have checked same problem exists even if I don't shorten my links. And I checked I am not alone, even the tech giant website mashable.com links also don't open in IE and FF from facebook, they only open in Chrome. From mobile phone the links don't open (redirected properly) even in chrome. Can anyone tell me what is the issue? Nothing much is written about it on Internet as no once has faced this problem. P.S: I have checked from different systems, the problem persists.

• Computer becomes unreachable on lan after some time

  - by Ashfame

  I work on my laptop and ssh into my desktop. I use a lot of key based authentication for many servers for work but recently I couldn't login because ssh would pick up and try all the keys and it stops trying before ultimately falling back to password based login. So right now I am using this command: ssh -X -o PubkeyAuthentication=no [email protected] #deskto The issue is after sometime the desktop would just become unreachable from laptop. I won't be able to open its localhost through IP and today I tried ping'in it and found a weird thing. Instead of 192.168.1.4, it tries to ping 192.168.1.3 which I am sure is the root cause as it just can't reach 192.168.1.4 when its actually trying for 192.168.1.3 Ping command output: ashfame@ashfame-xps:~$ ping 192.168.1.4 PING 192.168.1.4 (192.168.1.4) 56(84) bytes of data. From 192.168.1.3 icmp_seq=1 Destination Host Unreachable From 192.168.1.3 icmp_seq=2 Destination Host Unreachable From 192.168.1.3 icmp_seq=3 Destination Host Unreachable From 192.168.1.3 icmp_seq=4 Destination Host Unreachable From 192.168.1.3 icmp_seq=5 Destination Host Unreachable From 192.168.1.3 icmp_seq=6 Destination Host Unreachable From 192.168.1.3 icmp_seq=7 Destination Host Unreachable From 192.168.1.3 icmp_seq=8 Destination Host Unreachable From 192.168.1.3 icmp_seq=9 Destination Host Unreachable ^C --- 192.168.1.4 ping statistics --- 10 packets transmitted, 0 received, +9 errors, 100% packet loss, time 9047ms pipe 3 Also the ping command message comes in multiple and not one by one. (izx answer's the weirdness I thought there was in ping command.) I did check for desktop, its local IP is still the same, so something is going on in my laptop. Any ideas? P.S. - Laptop runs Ubuntu 12.04 & Desktop runs Ubuntu 11.10 Laptop is connected through wifi to router and Desktop is connected through LAN to router. Update: Even after setting up static IP leases in router settings, I again ran into this issue.

• Buffer System For Items

  - by Ohmages

  I am going to reference this image of what I want to accomplish in JavaScript. This is the Diablo buffer system. This question may be a bit advanced (or possibly not even allowed). But I was wondering how you might go about implementing this type of system in a JavaScript game. Currently to implement such a system in JavaScript escapes me, and I am turning to SO to get some suggestions, ideas, and hopefully some insight in how I could accomplish this without being to costly on the CPU. Some thoughts of mine for implementing such a system would be to: Create DIVS within a DIV that hold each position of the inventory Go through each item you own in a container and see which DIV it belongs to Make said item images the DIVs image This type of system might possibly work if ALL items were 1x1, but for this example its not going to work out. I am at a complete lost of ideas how to even accomplish this. Although, maybe rendering directly to the canvas and checking mouse cords could work, there would more than likely be A HUGE annoyance when checking if other items are overlapping each other (meaning you cant place the item down, and possibly switching item with the cursor item ). That said, what am I left with? Do I need to makeshift my own hack system with messy code, or is there some source out there (that I don't know about) that has replicated this type of system in their own game. I would be very grateful to get some replies on how you might go about doing this, and will accept answers that can logically explain how you might implement such a system (code is not required). P.S. Id like to use pure JavaScript, and nothing else (even though it might be "reinventing the wheel", I also like to learn).

• First ATMs programming language

  - by revo

  First ATMs performed tasks like a cash dispenser, they were offline machines which worked with punch cards impregnated with Carbon and a 6-digit PIN code. Maximum withdrawal with a card was 10 pounds and each one was a one-time use card - ATM swallowed cards! The first ATM was installed in London in the year 1967, as I looked at time line of programming languages, there were many programming languages made before that decade. I don't know about the hardware neither, but in which programming language it was written? *I didn't find a detailed biography of John Shepherd-Barron (ATM inventor at 70s) Update I found this picture, which is taken from a newspaper back to the year 1972 in Iran. Translated PS : Shows Mr. Rad-lon (if spelled correctly), The manager of Barros (if spelled correctly) International Educational Institute in United Kingdom at the right, and Mr. Jim Sutherland - Expert of Computer Kiosks. In the rest of the text I found on this paper, these kind of ATMs which called "Automated Computer Kiosk" were advertised with this: Mr. Rad-lon (if spelled correctly) puts his card to one specific location of Automated Computer Kiosk and after 10 seconds he withdraws his cash. Two more questions are: 1- How those ATMs were so fast? (withdrawal in 10 seconds in that year) 2- I didn't find any text on Internet which state about "Automated Computer Kiosk", Is it valid or were they being called Computer in that time?

• Maintaining Two Separate Software Versions From the Same Codebase in Version Control

  - by Joseph

  Let's say that I am writing two different versions of the same software/program/app/script and storing them under version control. The first version is a free "Basic" version, while the second is a paid "Premium" version that takes the codebase of the free version and expands upon it with a few extra value-added features. Any new patches, fixes, or features need to find their way into both versions. I am currently considering using master and develop branches for the main codebase (free version) along side master-premium and develop-premium branches for the paid version. When a change is made to the free version and merged to the master branch (after thorough testing on develop of course), it gets copied over to the develop-premium branch via the cherry-pick command for more testing and then merged into master-premium. Is this the best workflow to handle this situation? Are there any potential problems, caveats, or pitfalls to be aware of? Is there a better branching strategy than what I have already come up with? Your feedback is highly appreciated! P.S. This is for a PHP script stored in Git, but the answers should apply to any language or VCS.

• Are short abbreviated method/function names that don't use full words bad practice or a matter of style?

  - by Alb

  Is there nowadays any case for brevity over clarity with method names? Tonight I came across the Python method repr() which seems like a bad name for a method to me. It's not an English word. It apparently is an abbreviation of 'representation' and even if you can deduce that, it still doesn't tell you what the method does. A good method name is subjective to a certain degree, but I had assumed that modern best practices agreed that names should be at least full words and descriptive enough to reveal enough about the method that you would easily find one when looking for it. Method names made from words help let your code read like English. repr() seems to have no advantages as a name other than being short and IDE auto-complete makes this a non-issue. An additional reason given in an answer is that python names are brief so that you can do many things on one line. Surely the better way is to just extract the many things to their own function, and repeat until lines are not too long. Are these just a hangover from the unix way of doing things? Commands with names like ls, rm, ps and du (if you could call those names) were hard to find and hard to remember. I know that the everyday usage of commands such as these is different than methods in code so the matter of whether those are bad names is a different matter.
