• Naming conventions: camelCase versus underscore_case ? what are your thoughts about it? [closed]

  - by poelinca

  I've been using underscore_case for about 2 years and I recently switched to camelCase because of the new job (been using the later one for about 2 months and I still think underscore_case is better suited for large projects where there are alot of programmers involved, mainly because the code is easier to read). Now everybody at work uses camelCase because (so they say) the code looks more elegant . What are you're thoughts about camelCase or underscore_case p.s. please excuse my bad english Edit Some update first: platform used is PHP (but I'm not expecting strict PHP platform related answers , anybody can share their thoughts on which would be the best to use , that's why I came here in the first place) I use camelCase just as everibody else in the team (just as most of you recomend) we use Zend Framework which also recommends camelCase Some examples (related to PHP) : Codeigniter framework recommends underscore_case , and honestly the code is easier to read . ZF recomends camelCase and I'm not the only one who thinks ZF code is a tad harder to follow through. So my question would be rephrased: Let's take a case where you have the platform Foo which doesn't recommend any naming conventions and it's the team leader's choice to pick one. You are that team leader, why would you pick camelCase or why underscore_case? p.s. thanks everybody for the prompt answers so far

• Ruby Shoes for non-trivial apps

  - by marcof

  I've been taking a look at Ruby Shoes for GUI development with Ruby. So far, it's been a pretty good experience for making simple apps. However, I am quite worried about being able to write large scale applications with it. For example, how would I go about using MVP pattern with this framework ? For now, I have not been able to not make presentation concerns leak into the view because of the lack of some kind of "data binding". I have code that looks like this : Shoes.app do @view = SampleView.new @presenter = SamplePresenter.new @view @label = para @view.sample_property button "Update sample_property" do @presenter.update_sample_property end end Here, the call to @presenter.update_sample_property updates @view.sample_property but the label is not updated accordingly. For this to work, I would have to make @presenter.update_sample_property to return a string, and then call @label.text = return_value, but I think that would violate the MVP principle of not having presentation logic in the view. I'm used to work in .Net with the MVP pattern so I don't know if the pattern applies correctly to Shoes like I tried to do. Are there any ressources out there for making non-trivial apps with Shoes ? Especially using the MVP pattern or something similar ? EDIT : I took a look at the shoebox to see what other people have achieved with the framework. Though I did not look through it extensively, at first sight it seems like they are all simple projects with no real purposes.

• Do I need to rebuild the array after putting in a new hot spare?

  - by Shade34321

  So my experience with RAID is minimal. So I figured I'd come and ask here. We have a 16 drive RAID system that have 15 drives in RAID 5 with a hot spare left over. Recently one of the drives in the RAID was giving errors so I cloned it over to the hot spare and put a new drive in it's spot. I made the new drive the hot spare as I was told. I was told to rebuild the array after putting in the new drive as a hot spare so I tried and wasn't able to. So my question is do I need to rebuild it and if so why did it tell me I couldn't. Thanks! UPDATE: So I've come back up to work and looked at the RAID and it pulled in the hot spare into the raid and kicked out another drive.

• Box2d - Attaching a fired arrow to a moving enemy

  - by Satchmo Brown

  I am firing an arrow from the player to moving enemies. When the arrow hits the enemy, I want it to attach exactly where it hit and cause the enemy (a square) to tumble to the ground. Excluding the logistics of the movement and the spin (it already works), I am stuck on the attaching of the two bodies. I tried to weld them together initially but when they fell, they rotated in opposite directions. I have figured that a revolute joint is probably what I am after. The problem is that I can't figure out a way to attach them right where they collide. Using code from iforce2d: b2RevoluteJointDef revoluteJointDef; revoluteJointDef.bodyA = m_body; revoluteJointDef.bodyB = m_e->m_body; revoluteJointDef.collideConnected = true; revoluteJointDef.localAnchorA.Set(0,0);//the top right corner of the box revoluteJointDef.localAnchorB.Set(0,0);//center of the circle b2RevoluteJoint m_joint = *(b2RevoluteJoint*)m_game->m_world->CreateJoint( &revoluteJointDef ); m_body->SetLinearVelocity(m_e->m_body->GetLinearVelocity()); This attaches them but in the center of both of their points. Does anyone know how I would go about getting the exact point of collision so I can link these? Is this even the right method of doing this? Update: I have the exact point of collision. But I still am not sure this is even the method I want to go about this. Really, I just want to attach body A to B and have body B unaffected in any way.

• Linux Mint does not start after renaming home directory

  - by RUBY

  I am new to linux and was just trying to rename the only directory in home from rk to rhk. I messed up the whole thing and the settings. Created some new thing named rhk which I can't remember as it got all messed up and Now I am getting nothing after Linux Mint 10(julia) boots up - no start menu, no panel, no taskbar nothing. I tried to work in the recovery mode and got some(downloaded) 216mb of something(in the repair broken packages) hoping that it might help but didn't help. Moreover whenver I have booted in it shows messages like Could not update ICEauthority file /home/rk./.ICEauthority there is a problem with the configuration server. (usr/lib/libconfig24/gconfsanitycheck2 exited with status 256) The panel encountered a problem while loading "OAFIID: GNOME_mintMenu" The panel encountered a problem while loading "OAFIID: GNOME_IndicatorApplet" Naulitis could not create the following reqiured folders: /home/rk/Desktop, /home/rk/.

• Windows 7 made 2 hour shift for Daylight Savings Time

  - by P a u l

  My win7-64 ultimate has set the clock ahead 2 hours. It appears to have done it in increments of 1 hour, with the second 1 hour shift made sometime today. The first, correct, shift for Daylight Savings was sunday morning. In the clock settings it says Mountain Time UTC-7, but the official time should be Mountain Time UTC-6. Update for Windows 7 (KB979306) IS installed. Microsoft appears to be able to turn even setting the clock into a hairball. I need the clock rock solid since I use the computer to record TV programs.

• Representation of data in application versus database

  - by user1815201

  I'm going to make an application that will be given data to put in a database. The data will for the most part be the same, but the way it is formatted will vary a lot (could be in anything from text files to .xls to .doc). I'm not a very experienced developer, but I can see some potential issues and I want to minimize them. First off I have decided to use the DAO pattern, so that I can easily support new file formats or file suddenly formatted in different ways. What I really wonder about though, is how I should manage the data itself within my application. I'm thinking that the database DAO should have models representing each table of the database with the same relations between them, to make the uploading process easy. But should the filesystem DAO's have to use the same models? I can imaging that when the database changes, the change will suddenly propagate throughout the entire system, all DAOs and models alike. And that is obviously a bad thing. I'm a little bit tired and out of time. Will update with what ever questions you have. Thanks!

• What's the easiest way to migrate one Mac OSX volume to another

  - by teabot

  I want to move a volume from a smaller drive to a larger unformatted one. What is the best way to achieve this? Ideally I'd like the new volume to have the same name as the older volume as it contains user accounts, and is a destination of various symlinks that I have on other volumes. Update: I used Carbon Copy Cloner in the end and it worked perfectly. I was able to simply rename the new volume in Finder to the same name as the old volume and then powered down and removed the old drive on which the volume lived. When I restarted, the new volume seamlessly worked in place of the old volume.

• The lifecycle of "cool"

  - by Dori

  I've been thinking lately about how some programming projects/products become "cool," and in particular, how that trend can later reverse. Here are two examples that might better explain my context: Textmate Whenever someone asks about text editors on OS X, the answer on the SE sites is an automatic "Textmate!" But looked at objectively: Textmate 1.0 shipped October 2004 Textmate 1.5 shipped January 2006 Textmate 2 was announced February 2006 As of September 2010, the currently shipping version is 1.5.9 In all of 2010, there have been a total of three posts on the Textmate blog At what point (if ever) do Textmate fans start thinking about switching to another text editor? When it breaks after some future Apple update? When alpha geeks they respect start recommending something else? Or? jQuery Whenever a JavaScript-related question is asked on the SE sites, the knee-jerk response is "jQuery!" I've seen it happen even when the question itself only required a single line of JavaScript. Or when the question could be better answered by using CSS. Do the answerers understand they're suggesting a blowtorch to light a candle? That they're recommending adding 70K or so of code to do something trivial? Or is it a symptom of "When you have a hammer, everything looks like a nail"—that is, jQuery is all they know how to do, so that's their recommendation? And do they understand that while they may know jQuery well, that doesn't necessarily mean that they know JavaScript? Is there a way to explain that learning JavaScript would make them better jQuery programmers? My bigger-picture questions: Is this niche focus primarily a trait of programmers? How do you get programmers to not immediately jump to recommending their personal favorites? What can motivate programmers to review their initial selection criteria and possibly modify their choice? Your thoughts?

• Microsoft Word Document Recovery seems unresolvable

  - by LarsTech

  We work on a server (Windows Server 2003 Enterprise) that a bunch of us developers remote in using Remote Desktop Connection, and now every "other" time I open up word I get this Document Recovery pane: As you can see, "Delete" and "Show Repairs" are disabled (I don't think this is my document). "Open" or "Save As" works, but it never marks this document recovered, it just keeps coming up every "other" time I open up word. I don't even care about this document. How can I remove this document from the list so that it doesn't come up anymore? Update: As per Moab's comment, I had the user delete the file. But the Document Recovery still shows up with that item every other time Word is opened. The only difference now is that clicking on "Open" produces this (obvious) message: How can I clear this list? BTW, the user that owned this document was never getting the Document Recovery pane.

• In Joomla In htaccess REQUEST_URI is always returning index.php instead of SEF URL

  - by Saumil

  I have installed joomsef version 3.9.9 with the Joomla 1.5.25. Now I want to set https for some of the section of my site(e.g URI starts with /events/) while wanting rest of all urls on http.I am setting rules in .htaccess file but not getting output as expected. I am checking REQUEST_URI of the SEF urls but always getting index.php as URI. Here is my htaccess code. ########## Begin - Custom redirects # # If you need to redirect some pages, or set a canonical non-www to # www redirect (or vice versa), place that code here. Ensure those # redirects use the correct RewriteRule syntax and the [R=301,L] flags. # ########## End - Custom redirects # Uncomment following line if your webserver's URL # is not directly related to physical file paths. # Update Your Joomla! Directory (just / for root) # RewriteBase / ########## Begin - Joomla! core SEF Section # RewriteRule .* - [E=HTTP_AUTHORIZATION:%{HTTP:Authorization}] # # If the requested path and file is not /index.php and the request # has not already been internally rewritten to the index.php script RewriteCond %{REQUEST_URI} !^/index\.php # and the request is for root, or for an extensionless URL, or the # requested URL ends with one of the listed extensions RewriteCond %{REQUEST_URI} (/[^.]*|\.(php|html?|feed|pdf|raw))$ [NC] # and the requested path and file doesn't directly match a physical file RewriteCond %{REQUEST_FILENAME} !-f # and the requested path and file doesn't directly match a physical folder RewriteCond %{REQUEST_FILENAME} !-d # internally rewrite the request to the index.php script RewriteRule .* index.php [L] # ########## End - Joomla! core SEF Section # Here is my code e.g site url is http://mydomain.com/events RewriteCond %{REQUEST_URI} ^/(events)$ RewriteCond %{HTTPS} !ON RewriteRule (.*) https://%{REQUEST_HOST}%{REQUEST_URI}/$1 [L,R=301] I am not getting why REQUEST_URI is reffering index.php even though my url in address bar is like this http://mydomain.com/events . I am using JOOMSEF(Joomla extension for SEF URLS).If I am removing other rules from the htaccess file then joomla stops working. I am not getting a way to handle this as I am not expert.Please let me know if someone has passed through same situation and have solution or suggest some work around. Thanks

• SVN do unnecessary chmod on .svn/tempfiles

  - by ???

  My working dir is on an TrueCrypt NTFS volume, with umask 000. So I can read/write on any files with no problem. But I can't do svn command on it, for example `svn update' shows error: svn: Can't set permissions on '.svn/tempfile.8.tmp': strace svn up gives: ... chmod("sbin/.svn/tempfile.2.tmp", 0770) = -1 EPERM (Operation not permitted) fcntl64(3, F_GETFL) = 0x2 (flags O_RDWR) fcntl64(3, F_SETFL, O_RDWR|O_NONBLOCK) = 0 write(3, "( failure ( ( 1 76:Can't set per"..., 172) = 172 fcntl64(3, F_GETFL) = 0x802 (flags O_RDWR|O_NONBLOCK) fcntl64(3, F_SETFL, O_RDWR) = 0 read(3, "( abort-edit ( ) ) ( failure ( ("..., 4096) = 191 gettimeofday({1276661368, 382789}, NULL) = 0 lstat64("sbin", {st_mode=S_IFDIR|0770, st_size=0, ...}) = 0 select(0, NULL, NULL, NULL, {0, 1000}) = 0 (Timeout) write(2, "svn: Can't set permissions on 's"..., 82svn: Can't set permissions on 'sbin/.svn/tempfile.2.tmp': Operation not permitted) = 82 close(3) = 0 So, the error occurred when svn chmod on some tmp files. But this is disallowed in the TrueCrypt volumes, and it's just unnecessary. Can I bypass the chmod lib calls when launch svn on TrueCrypt volumes?

• How can I install Insight debugger?

  - by DandyWalker

  Hello. I am following along a book in which Insight debugger is required. I didn't find it on my Maverick. I googled and I found that it's not supported in debian anymore but I really need to install it. I tried to compile the source and it installed but keep telling me that tk is missing whenever i start it. I installed tk with sudo aptitude install tk then tried to run again it's the same. I compiled it one more time and nothing really changes. So please how can I install that ? Update: This is the message i get Tk_Init failed: Can't find a usable tk.tcl in the following directories: /usr/local/share/tk8.4 /usr/local/lib/tk8.4 /usr/lib/tk8.4 /usr/local/library /usr/library /usr/tk8.4.1/library /tk8.4.1/library /usr/local/share/tk8.4/tk.tcl: no event type or button # or keysym no event type or button # or keysym while executing "bind Listbox <MouseWheel> { %W yview scroll [expr {- (%D / 120) * 4}] units }" (file "/usr/local/share/tk8.4/listbox.tcl" line 182) invoked from within "source /usr/local/share/tk8.4/listbox.tcl" (in namespace eval "::" script line 1) invoked from within "namespace eval :: [list source [file join $::tk_library $file.tcl]]" (procedure "SourceLibFile" line 2) invoked from within "SourceLibFile listbox" (in namespace eval "::tk" script line 4) invoked from within "namespace eval ::tk { SourceLibFile button SourceLibFile entry SourceLibFile listbox SourceLibFile menu SourceLibFile panedwindow SourceLibFile ..." invoked from within "if {$::tk_library ne ""} { if {[string equal $tcl_platform(platform) "macintosh"]} { proc ::tk::SourceLibFile {file} { if {[catch { namesp..."

• Reset Network Load Balancer Connection Pool

  - by bill_the_loser

  I am currently working on load testing a web application on a virtual machine cluster. I am looking for a way to flush the connection pool / NLB cache so that it is like each machine connecting to the NLB is connecting for the first time and doesn't get directed back to the node that it was on last time. This a Windows 2003 Server cluster, behind a Microsoft software based Network Load Balancer. Additional Information: To do the load testing I'm using virtual machines, one for each node on the cluster. Somehow I got two virtual machines connecting to the same node and I'm looking for an easier way to reset those connections without going in to the NLB Manager and stopping and starting each node on the NLB. Update: We went ahead and changed the affinity on all of the nodes of the cluster to none. Now it's a non-issue.

• Why does tomcat like deleting my context.xml file?

  - by staticsan

  I'm developing a web-based Java application at work and (obviously) have to run it locally during development. I've figured out the Tomcat docs and have a suitable context.xml file in /etc/tomcat6/Catalina/localhost/ but every so often, Tomcat decides to delete it! Which means I have to put it back and restart Tomcat. Why does it do this? I have searched the Tomcat docs about it and am none the wiser. (Oh yes: it's not actually called context.xml but owners.xml as that's the HTTP path prefix for this application.) Update I've now seen Tomcat delete the file whilst Tomcat was running. I think I need to file a bug...

• 1and1: Unable to host an external domain

  - by Django Reinhardt

  I'm sorry if this isn't the right place for this question, but I'm presently having difficulties with my hosting provider (1and1). Two weeks ago, two of my clients bought hosting from them on my recommendation, but as it turned out, 1and1 are having severe technical difficulties. Right now non of their hosting packages are able to accept ANY external domains. So either you pay the costs of transferring the registrar of your domain, or you use the ugly 1and1 domain name. Not any good for a hosting company of 1and1's reputation! They have been promising me for two weeks that they're going to fix the problem, but as you have probably guessed by now, that hasn't been the case. I would like to know if a) Anyone else is in the same boat as me, and b) If there are other comparably reputable hosting providers that I should consider moving to instead? Very disappointing! :( Note: This is for 1and1 in the UK. I imagine it isn't affecting users in other countries(?) Clarification: 1and1 are unable to accept ANY external domains. That means that even if you update your DNS details on your domain, their system cannot be updated to add your external domain to your account.

• Defense Manpower Data Center Wins Award for Excellence in the Workforce

  - by Peggy Chen

  The Defense Manpower Data Center milConnect website recently won the 2012 Excellence.gov Award for Excellence in the Workforce. Defense Manpower Data Center milConnect is a centralized, online resource that provides military service members (active and retired) and their families (over 42 million in total) quick access to their profile, health care enrollments, benefits, and other military-related topics. An easy to use, safe and secure website, milConnect also provides service members with convenient access their personnel and service-related information. The self-service website allow users to quickly and easily find and, where applicable, update their information in the Defense Eligibility Reporting System (DEERS) and milConnect transmits information to and from one reliable source safely and securely.  The Defense Manpower Data Center (DMDC) maintains the largest, most comprehensive central repository of personnel, manpower, casualty, pay, entitlement, personnel security, person identity and attributes, survey, testing, training, and financial data in the Department of Defense (DoD).  This is one of the largest systems of record in the world. milConnect had the challenge of modernizing the user experience for over 42 million users. With records in over 22 applications and 25 interfaces in hundreds of existing systems, milConnect needed to reduce the complexity of multiple authentication sources as well as consolidating access to existing systems with sensitive information. It accomplished this using a service-orientated architecture, enterprise security and access and identity management for self-service access on a massive scale. By providing 24x7x365 secure access and handling over 5 million transactions daily, not only has milConnect, built on Oracle WebCenter, streamlined and improved the customer experience for military personnel and families. it has also done so while cutting costs, allowing self-service access, and promoting electronic government. Congrats to Defense Manpower Data Center and milConnect!

• OS X Snow Leopard fails to boot after upgrade to 10.6.1

  - by pixeline

  I'm a fairly recent mac user. Been using windows for decades and happily switched. But i upgraded from 10.6 to 10.6.1 last night and the upgrade looks like it failed. I restarted the machine when it asked to then went to bed. In the morning the computer was still trying to shut itself off. So i forced the shutdown, restarted, but now i'm stuck with the loading spinner. What can i do? UPDATE: Verbose didn't show anything interesting. i also did the hardware test. Nothing comes up wrong. Disk utility did not find any error on the HD. But, it did show a fatal error when checking permissions.

• How to advocate Stack Overflow at work

  - by Gordon

  I am thinking of doing a short presentation at work about using Stack Overflow as a resource for your day job. What is the experience doing this? Would you deem it a valid resource to tell you colleagues about or is it similar to telling them about Google as a resource? Is there a better way of doing it? I was leaning toward asking questions side of Stack Overflow rather than answering them to avoid you-shouldn't-be-doing-this-on-work-time argument. Just as a follow up. Originally I didn't want to make the question to specific to my own case. My presentation will only be a quick four minute talk, which I will repeat over an hour to different groups. I may ask a question before the talk on Stack Overflow and refer to it during the presentation. Hopefully I will get some activity during the hour. I am also going to talk briefly about some of the other Stack Exchange sites that would fit the audience as they are not all developers. I think Super User, Server Fault and Programmers should work well. I will not be doing the presentation for another couple of months as it has be rescheduled, but I will update on how I got on.

• Encrypting a non-linux partition with LUKS.

  - by linuxn00b

  I have a non-Linux partition I want to encrypt with LUKS. The goal is to be able to store it by itself on a device without Linux and access it from the device when needed with an Ubuntu Live CD. I know LUKS can't encrypt partitions in place, so I created another, unformatted partition of the EXACT same size (using GParted's "Round to MiB" option) and ran this command: sudo cryptsetup luksFormat /dev/xxx Where xxx is the partition's device name. Then I typed in my new passphrase and confirmed it. Oddly, the command exited immediately after, so I guess it doesn't encrypt the entire partition right away? Anyway, then I ran this command: sudo cryptsetup luksOpen /dev/xxx xxx Then I tried copying the contents of the existing partition (call it yyy) to the encrypted one like this: sudo dd if=/dev/yyy of=/dev/mapper/xxx bs=1MB and it ran for a while, but exited with this: dd: writing `/dev/mapper/xxx': No space left on device just before writing the last MB. I take this to mean the contents of yyy was truncated when it was copied to xxx, because I have dd'd it before, and whenever I have dd'd to a partition of the exact same size, I never get that error. (and fdisk reports they are the same size in blocks). After a little Googling I discovered all luksFormat'ted partitions have a custom header followed by the encrypted contents. So it appears I need to create a partition exactly the size of the old one + however many bytes a LUKS header is. What size should the destination partition be, no. 1, and no. 2, am I even on the right track here? UPDATE I found this in the LUKS FAQ: I think this is overly complicated. Is there an alternative? Yes, you can use plain dm-crypt. It does not allow multiple passphrases, but on the plus side, it has zero on disk description and if you overwrite some part of a plain dm-crypt partition, exactly the overwritten parts are lost (rounded up to sector borders). So perhaps I shouldn't be using LUKS at all?
