• Installing Ruby on Rails without access to command line

  - by Darwin

  I'm VERY new to this whole web dev thing but I can program and I liked Ruby when I used it before. Now, I've got web hosting and a domain and a site on there that's currently ran under Joomla but I'd like to experiment with Rails. The most access I can get to the server is FTP and maybe a setting here and there in the control panel. Definitely no command line. Is there a way to just, I don't know, upload ruby on rails to a folder and run it in a browser? That's how Joomla works I think. Literally every article I read about this starts with "you just do sudo get..." mumbo jumbo.

• What Would You Consider Best Practice Workflow Tools For Web Application (PHP) Development?

  - by Zenph

  I'm really hoping somebody with more experience can edit the question as per my examples of answers: • using version control • test driven development • debugging code (xdebug for php) • use of UML diagrams • use of OOP for maintainable, reusable code • use of frameworks (like Zend Framework for php) for rapid application development Anything else or an elaboration of what I mentioned above? Basically, I'm in the middle of forming a team of developers (I'm a developer myself) and I'd like some advice on how professional programmers/designers etc should work together and what standards/paradigms they should use. Also, if anybody has any books or links on the subject I'd welcome that! I did find this which I guess satisfies what I'm looking for, or at least part thereof: http://www.ibm.com/developerworks/websphere/library/techarticles/0306_perks/perks2.html

• Confusion installing mongodb manually because of sitting behing a proxy

  - by black sensei

  I am forced to install mongodb manually on an Ubuntu server because the machine sits behind a proxy and there is no way to temporary open port 11371 for key exchange to happen. I am following this official mongoDB tutorial. So I downloaded the tgz and extracted it in /usr/local/bin/mongodb. Where I got confused is when assigning the ownership of the /data/db to the user mongo. So who creates the user mongo? How to get control-scripts working?

• Mercurial release management. Rejecting changes that fail testing

  - by MYou

  Researching distributed source control management (specifically mercurial). My question is more or less what is the best practice for rejecting entire sets of code that fail testing? Example: A team is working on a hello world program. They have testers and a scheduled release coming up with specific features planned. Upcoming Release: Add feature A Add feature B Add feature C So, the developers make their clones for their features, do the work and merge them into a QA repo for the testers to scrutinize. Let's say the testers report back that "Feature B is incomplete and in fact dangerous", and they would like to retest A and C. End example. What's the best way to do all this so that feature B can easily be removed and you end up with a new repo that contains only feature A and C merged together? Recreate the test repo? Back out B? Other magic?

• Seperate .com domain name purchasing for a VPS

  - by adamk

  I am looking at getting a VPS with RackSRV, and they don't sell domain names, but are happy to set it up after I get one elsewhere. Can anyone recommend somewhere I can purchase just the domain, and not have any hassles moving it afterwards? (Or can I just purchase the domain and make it point at the RackSRV ip address, while still using the domain sellers' control panel? I don't really understand that part of it enough! :)) I want the domain name registered in my name, ideally with myself as the technical and administrative contacts for simple transfers.

• Looking for the better way to combine deep architecture refactoring with feature based development

  - by voroninp

  Problem statement: Given: TFS as Source Control Heavy desktop client application with tons of legacy code with bad or almost absent architecture design. Clients constantly requiring new features with sound quality, fast delivery and constantly complaining on user unfriendly UI. Problem: Application undoubtedly requires deep refactoring. This process inevitably makes application unstable and dedicated stabilization phase is needed. We've tried: Refactoring in master with periodical merges from master (MB) to feature branch (FB). (my mistake) Result: Many unstable branches. What we are advised: Create additional branch for refactoring (RB) periodically synchronizing it with MB via merge from MB to RB. After RB is stabilized we substitute master with RB and create new branch for further refactoring. This is the plan. But here I expect the real hell of merging MB to RB after merging any FB to MB. The main advantage: Stable master most of the time. Are there any better alternatives to the procees?

• Confusion about Rotation matrices from Euler Angles

  - by xEnOn

  I am trying to learn more about Euler Angles so as to help myself in understanding how I can control my camera better in the game. I came across the following formula that converts Euler Angles to rotation matrices: In the equation, I could see that the first matrix from the left is the rotation matrix about x-axis, the second is about y-axis and the third is about z-axis. From my understanding about ordinary matrix transformations, the later transformation is always applied to the right hand side. And if I'm right about this, then the above equation should have a rotation order starting from rotating about z-axis, y-axis, then finally x-axis. But, from the symbols it seems that the rotation order start rotating about x-axis, then y-axis, then finally z-axis. What should the actual order of the rotation be? Also, I am confuse about if the input vector, in this case, would be a row vector on the left, or a column vector on the right?

• Review before or after code commit, which is better?

  - by fifth

  Traditionally we performed code review before commit, I had an argument with my colleague today, who preferred code review after commit. First, here's some background, we got some experienced developers and we also got new hires with almost zero programming practice. we'd like to perform fast and short iterations to release our product. we all team members locate at same site. The advantages of code review before commit I've learned, mentor new hires try to prevent errors, failures, bad designs in early developing cycle learn from others knowledge backup if someone quits But I also got some bad experience, like low efficiency, some changes may be reviewed over days hard to balance speed and quality, especially for newbies some guy felt distrust As to post-review, I just knew little about this, but the most thing I worried about is the risk of losing control, people never review. Any opinions?

• VNC Server not responsive after a few days

  - by assylias

  I am new to Ubuntu (11.10) - I installed Ubuntu on a box which has no screen and no keyboard. I connect to that box via tightvncserver. The box is mostly used as a file and media server (i.e. samba + XBMC). So far so good. I can connect via VNC to the box and take control of it. But after a few days, when trying to connect via VNC, I don't get a response. The media server is still on, ping is fine, but VNC is down. The only solution I have found is to plug a screen and keyboard and reboot. I am not sure how to diagnose the problem (maybe some log files?) or if this is just a configuration issue. Any help appreciated.

• Installing linux on OCZ RevoDrive3 x2

  - by user2101712

  First of all, here is the configuration of my computer: Motherboard: Asus H87Plus RAM: Corsair Vengeance 32GB Processor: Intel i7 4770 Drive: OCZ RevoDrive 3 x2 (240 GB) (OCZ Revodrive3 is a PCIe module) I am trying to install the latest version of Ubuntu Desktop (13.10). The problem is that in the UEFI (bios) the drive shows up as a 240 GB drive, but in the Ubuntu installer it shows up as two 120 GB drives. If I install Ubuntu in any of these two drives, it never boots. The screen flickers a few times and comes back to the UEFI menu. I have tried reading up and have come across information that the drive has a "fakeraid", and the solution is to use dmraid. However, when I give the following commands in the terminal (from live CD): # modprobe dm_mod # dmraid -ay it says: no raid disks. And the following command: # ls -la /dev/mapper/ just shows /dev/mapper/control How can I install Ubuntu on my computer? what is the correct method?

• ISO 12207: SQA as a supporting process?

  - by user970696

  I have been following ISO12207 for the sake of my thesis dealing with software quality. Now I should explain quality assurance and here comes the problem: according to this norm, QA is a supporting process, separated but on the same level with verification, validation and auditing processes. According to other sources, Quality Assurance is basically high level activity making sure that standards, norms etc. are being followed. Usually the part of Quality Assurance is the Quality Control (testing, reviewing, inspections also V&V) which measures the quality and provides QA with this information so it can be acted upon. I somehow do not understand how QA is thought to be according to this ISO and what activities should it perform. Also it does not mention QC except for a footnote.

• Rehosting content from another server

  - by Lana_M

  We have a set of static pages that will augment a customer's existing site. The pages will not reside on the customer's servers for logistical reasons and because we need to maintain control of the content. The plan is for the customer to set up a mod_rewrite rule that will funnel certain types of URLs to a single server-side handler script that will grab the appropriate file from a CDN and just output its content. This illustrates the approach: <?php echo(file_get_contents(str_replace($customer_host, $cdn_host, $_SERVER['REQUEST_URI']))); ?> Can anyone think of pitfalls or offer up a different approach? Is there some way to circumvent a script altogether?

• atheros wireless ar9285 driver

  - by nikola

  I have been having problems with wireless on Ubuntu 10 and above, Mint 11 and above. The problem is in the driver for the wireless... I can see that there is no driver installed and yet it works but reduced a lot, for example: on windows 7 ultimate 100% on distance of 1 meter (currently running) Mint Cinnamon 15 on same distance 70% when it goes under the 40 % it simply disconnects and than takes a lot of time to connect again I am new to Linux and I don't know anything about programming, yet I love the interface and look of the OS but don't want to reject it for couple of problems. There is, however, a problem with brightness control on laptop, it shows the notification and slider but with no effect The question is: Can somebody explain to me where to download and how to install the ar9285 driver for atheros wireless card laptop acer emachines eme529? or can someone explain this to me only for the LINUX MINT 15 http://www.jrhenkelmann.net/index.php?option=com_content&task=view&id=34 because the synaptic's interface is different than of mint 15 I KNOW this is Ubuntu community but the problems persist in all Linux versions

• Quality Assurance tools discrepancies

  - by Roudak

  It is a bit ironic, yesterday I answered a question related to this topic that was marked to be good and today I'm the one who asks. These are my thoughts and a question: Also let's agree on the terms: QA is a set of activities that defines and implements processes during SW development. The common tool is the process audit. However, my colleague at work agrees with the opinion that reviews and inspections are also quality assurance tools, although most sources classify them as quality control. I would say both sides are partially right: during inspections, we evaluate a physical product (clearly QC) but we see it as a white box so we can check its compliance with set processes (QA). Do you think it is the reason of the dichotomy among the authors? I know it is more like an academic question but it deserves the answer :)

• Adding PPA on install

  - by trampster

  I have a app I am packaging for ubuntu. I don't like the idea that if included in the ubuntu repositories I will have no control over updating that application. I don't want my users stuck on an out dated version for up to 6 months. I also do not want my users to have to manually add a PPA themselves to get updates as the target user will not have the technical know how to do this. Is it OK to have my .deb add a PPA on install. So that I can roll out stable updates to my ubuntu users.

• How can I manage keyboard shortcuts in 11.10 Oneric?

  - by Mike

  In 10.04, I've had a keyboard shortcut defined via it's keyboard settings applet. Recently I have upgraded to 11.10 (I use gnome-classic). This shortcut still works, but I can't find it in System Setting's Keyboard applet. This means I don't know how to disable it. Not that it bothers me too much (now, at least), but not being able to control my own computer doesn't seem very pleasant. Where does Ubuntu store my keyboard shortcuts? BTW, I do not use compiz, and I can't find my shortcut in gconf either.

• Windows 7/ 12.04 Dual Boot Mess

  - by Ben

  I am certainly new to ubuntu (linux in general)... I added ubuntu 12.04 as a dual boot to a brand new desktop which had win 7 pre-installed. Both work well Then I tried to change the order of the boot menu to make Ubuntu first and Win7 second... I did this from the windows side (it seems that my setup is relying on windows bootloader, which I don't think I need to change) using the built-in startup manager (I think that's what windows calls it- it's in the control panel). I set Ubuntu as first (default if no user input). then... I ACCIDENTALLY ("hmmm...I wonder what this button does?") set the menu timeout to "0" Now, I cannot change the menu timeout (because I cannot get into windows) and without doing so, I cannot select windows as the OS I would like to boot(I cannot get into windows). Any Ideas?

• Attach a Wordpress.org blog to my BigCommerece Store as a sub-domain

  - by user1323814

  I am stuck in a peculiar situation. I have a store on BigCommerece configured with a domain from GoDaddy (mystore.com). I recently created a custom wordpress blog and hosted it on 1and1 hosting (s418783372.onlinehome.us), since bigcommerece can't host Wordpress. Now I want to use it from a sub-domain of my main-bigcommerece store (models.mystore.com), but it doesn't seem to be working since BigCommerce is the Doman Manager, but GoDaddy is the Domain-Registrar and 1and1 is the host so it doesn't control the domain. I have tried setting up a CNAME record on BigCommerece and when it didn't work asked BigCommerece about it, but they said they can't do anything about it since they aren't the domain registrar and gave me a message saying: The responsiblity to show the name in the browser on the site is up to the server or site admin. The Cname can only get the browser there

  Hello all, I think I'm struggled in some situation! We are a new start-up with 5 employees (2 Programmers). I'm the Technical Manager and that was so fine! Now I can see the fingers point to me to take the control of everything, as I've the big vision of what our organization do and play the role of CEO or General Manager! I want to, but I've no idea if it would be risky to our organization to make such a decision? How would managerial interrupts affect the technical productivity? Any tips or previous experience about such situation would help :) Thanks in advance!

• Oracle Service Contracts – Calculate Estimated Tax with Higher Accuracy

  - by LuciaC-Oracle

  On a Service Contract the tax rate and its effectivity can change over the contract duration.  Hence, service organizations need to provide an accurate picture of the estimated tax that the customer might end up paying.  Prior to Release 12.1.3+, the Oracle Service Contracts application calculated the estimated tax based on the line/ sub line start date.  With Release 12.1.3+ (via Patch 16601269:R12.OKS.B) , new functionality provides users with an option to calculate tax at contract billing schedule level, thereby considering the changes in tax rate effectivity at that level.A new profile option 'OKS: Calculate Tax at Schedule' has been introduced which can be used to control whether the existing or new functionality is used.  If the profile is set to 'Yes' the application calculates tax at the billing schedule level for all lines/ sub lines.  For more details on the implementation steps and functionality, please refer to Doc ID 1676700.1: Oracle Service Contracts – How To Calculate Estimated Tax with Higher Accuracy.
