• Employer purchased a Macbook for me, as a programmer what do I need to do to get my environment setup?

  - by Chris

  I come from growing up on dos/windows and the more I got into programming and development the more I invested time/effort into linux distributions. I had a choice between an IBM and a Macbook. I went with the Macbook to get some experience but I am not really sure where to start? I find myself wanting to install virtualbox and boot up linux. Any advice for a new Mac user who wants to get back up to speed with programming efficiently?

• What can I do to encourage teams to lighten up? [closed]

  - by Rahul

  I work with a geographically distributed team (different timezones) with people from various cultures and background. Some of us have never met each other in person but we communicate with each other over phone, chat and email almost on an hourly basis. Most of our meetings and discussions are dead serious and boring. What's worse, any attempt at humor is not very well received because of cultural differences. I feel that we are all taking our work a bit too seriously. We don't shy away from painful arguments, nasty emails and heated discussions when things go wrong but never attempt to develop camaraderie or friendships in better times. I would like to know your experiences with such situations and what, if anything, did you do to lighten things up at workplace.

• What Part of Your Project Should be in Source Code Control?

  - by muffinista

  A fellow developer has started work on a new Drupal project, and the sysadmin has suggested that they should only put the sites/default subdirectory in source control, because it "will make updates easily scriptable." Setting aside that somewhat dubious claim, it raises another question -- what files should be under source control? And is there a situation where some large chunk of files should be excluded? My opinion is that the entire tree for the project should be under control, and this would be true for a Drupal project, rails, or anything else. This seems like a no-brainer -- you clearly need versioning for your framework as much as you do for any custom code you write. That said, I would love to get other opinions on this. Are there any arguments for not having everything under control? Is this sysadmin a BOFH?

• Can casper use a squashfs in the initrd?

  - by Max Brustkern

  I've built a very large initrd containing a full squashfs from a desktop image, and used it to boot a machine over PXE. Unfortunately, casper cannot seem to locate the squashfs, since it's not present on any of the block devices it scans. Is there some way I can force it to check the initrd, or point to a filesystem location there in the bootfrom parameter? I've tried using bootfrom=/ with the casper directory in the root of the initrd, and that didn't seem to work.

• Tutorial: Why Use GRUB2? Good Question! (part 3)

  As we come to the end of Akkana Peck's excellent series on mastering GRUB2, it's not clear what advantages it has over legacy GRUB, or even good old LILO. It seems it's gone backwards. In today's installment we learn how to translate some common and mysterious error messages, and how to manage a multi-boot system with GRUB2.

• Subscribe/Publish Model in Web-based Application (c#) - Best Practices for Event Handlers

  - by KingOfHypocrites

  I was recently exposed to a desktop application that uses an publish/subscribe model to handle commands, events, etc. I can't seem to find any good examples of using this in a web application, so I wonder if I am off base in trying to use this for web based development (on the server side)? I'm using asp.net c#. My main question in regards to the design is: When using a publish/subscribe model, is it better to have generic commands/events that pass no parameters and then have the subscribers look at static context objects that contain the data relevant to the event? Or is it better to create custom arguments for every event that contain data related to the event? The whole concept of a global container seems so convenient but at the same time seems to break encapsulation. Any thoughts or best practices from anyone who has implemented this type of model in a web based application? Even suggestions on this model out of the scope of my question are appreciated.

Do I need to get a graphics card to fix or will software tweaks solve this?

• Is C++ really a bad language for beginners? [duplicate]

  - by Chris

  This question already has an answer here: Is C++ suitable as a first language? 24 answers I'm learning C++ right now, and it's the first language I'm learning. I keep seeing on stackexchange and other forums (Reddit, etc.) that I should drop C++ and learn a higher level language like Python or Java. The only arguments I see are that "C++ is harder to learn and is more low-level than others." which don't really give a reason NOT to learn it. I want to know if there are any actual reasons for dropping C++ and taking up another, "easier" language. Or if I should keep focusing on it, and just learn others later (which is what I plan on doing).

• Several classes need to access the same data, where should the data be declared?

  - by Juicy

  I have a basic 2D tower defense game in C++. Each map is a separate class which inherits from GameState. The map delegates the logic and drawing code to each object in the game and sets data such as the map path. In pseudo-code the logic section might look something like this: update(): for each creep in creeps: creep.update() for each tower in towers: tower.update() for each missile in missiles: missile.update() The objects (creeps, towers and missiles) are stored in vector-of-pointers. The towers must have access to the vector-of-creeps and the vector-of-missiles to create new missiles and identify targets. The question is: where do I declare the vectors? Should they be members of the Map class, and passed as arguments to the tower.update() function? Or declared globally? Or are there other solutions I'm missing entirely?

• Install Script Question

  - by Michael Dobbins

  Sorry if this has been discussed, wasn't sure what to use to search for the particular question I had. I'm installing sickrage and couchpotato and headphones, and will be doing multiple installs I made a small batch script just to install everything but what I don't know how to do is automatically make them auto start on boot. Since they all require a file to be created I do not know how to make this file auto create and populate what needs to be put into it.

• 13.04: update-initramfs works but mkinitramfs fails from APT

  - by Phil2.0

  I'm experiencing a strange thing, I've freshly upgraded from 12.10 to 13.04, Everything is fine except that it can't build the initrd image automatically, it fails and prints out the mkinitramfs's Usage output. I tried to debug the "mkinitramfs" script and it appears the $outfile variable is never set. However, I'm able to produce the ramdisk manually like follow: update-initramfs -c -u 3.0.8-23-generic I tried most of the stuff seen on the net: purge, reinstall but no help but nothing, and I can't use linux-image is marked as "broken" but the kernel exists in /boot.

• Deleted Myself from Admin Group - Now Getting Error usermod: cannot lock /etc/passwd; try again later

  - by BubbaJ

  I have a laptop with Ubuntu 11.10 that is shared between myself and two other family members. My user id was setup as the only "Administrator" on the laptop. The other users were setup as "Standard" users. In my attempt to try to add myself to the user groups for the other users, I somehow deleted myself from the admin groups. I used the "usermod" command from the terminal. I must have neglected to include the proper switches or syntax for the update. It looks like I successfully added my userid to the group associated with my wife's account. When I use the "groups" command, I can see only my id and my wife's id in the list. I no longer see the "admin" or "adm" groups, and others that used to be listed. When I go into System Settings User Accounts it looks like my ID is now listed as a "Standard" user. I would like to change my account back to "Administrator", but now I can't. I did some searches for solutions and found that I would need to boot into Recovery Mode and execute the usermod command from the root session. I was able to successfully boot into Recovery Mode and get to the root session. I was trying to execute the command "usermod -a -G admin user1" to add my id (user1) back to the admin group. When I execute the command from the root session, I get the error message "usermod: cannot lock /etc/passwd; try again later". I tried preceding the usermod command with "sudo", but it didn't make a difference, same error. I then tried adding a new user using adduser, thinking I would try to create a new userid and make the new userid part of the admin group. I get the same error using the adduser command. I saw some posts that recommend looking for and deleting files that end in ".lock" in the etc directory. The only file I found was .pwd.lock which I haven't touched. I am at a loss as to what to try next. I am relatively inexperienced with Ubuntu and Linux, so alot of this is new to me. Any help you can provide would be much appreciated.

• chown select files only

  - by user114642

  I use the (excellant) unison to sync two file servers and I've just realised i've synced a number of files without using the switch in unison that maintains the file user ownership. these files now have a user of root (coz i have to run unison as root) Can I chown to a specified user BUT only change the files that now have the owner root and do so recursively in the directory in question? Sure i can but not sure of the arguments to "find files with owner 0 and change them to owner xxxx". THX for any help...

• Demographics and Interests reports

  - by Dyf

  I have an issue with Google Analytics, can't seem to find a guide how to activate Demographics and Interests reports. I am using the new version of analytics (Universal Analytics) and the script code looks something like this: (function (i, s, o, g, r, a, m) { i['GoogleAnalyticsObject'] = r; i[r] = i[r] || function () { (i[r].q = i[r].q || []).push(arguments) }, i[r].l = 1 * new Date(); a = s.createElement(o), m = s.getElementsByTagName(o)[0]; a.async = 1; a.src = g; m.parentNode.insertBefore(a, m) })(window, document, 'script', '//www.google-analytics.com/analytics.js', 'ga'); But the guide i found on googles page (https://support.google.com/analytics/answer/2819948?hl=sv) is for the old version (Classis Analytics). Anyone know how i can activate this on Universal Analytics or is this even possible? Thanks!

  Lot of things has been discussed that can be taken as negative things about programmers, Lets discussed about something good and unexpected happenings in your programmer life... Like: (after R&D of two days and a lot of disappointments ) You just spend an hour with your PM to explain that some feature having some problem and we are unable to release this module in today's beta... after a lot of arguments you are given an hour to make your app work without this module, you sit on your workstation to make a release and all of a sudden you found a silly problem behind that module..... (you solve it and prepare a desired build) did you face miracle (= sudden, positive surprises?) in your life?? what was your reaction in case you have come through such experience?? (N.B. I know my English is not that good and that's why I'm open to every linguistic mistakes needed to be corrected)
