  • When do you change your major/minor/patch version number?

    - by dave4351
    Do you change your major/minor/patch version numbers right before you release or right after? Example: You just released 1.0.0 to the world (huzzah!). But wait, don't celebrate too much. 1.1.0 is coming out in six weeks! So you fix a bug and do a new build. What's that build called? 1.1.0.0 or 1.0.0.xxxy (where xxxy is the build number of 1.0.0 incremented)? Keep in mind you may have 100 features and bugs to go into 1.1.0. So it might be good to call it 1.0.0.xxxy, because you're nowhere close to 1.1.0. But on the other hand, another dev may be working on 2.0.0, in which case your build might be better named 1.1.0.0 and his 2.0.0.0 instead of 1.0.0.xxxy and 1.0.0.xxxz, respectively.

  • 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.

  • Best practices on separating Update and Draw on game loop

    - by Galvanize
    I've been working on my first HTML5 prototype and I found a good model that uses the regular Update and Draw loop we see in game dev. My question is, where does one end and the other begins? The question popped when I wanted to rotate and draw an Image, and I kept wondering if the work of changing the tranformation matrix (that I presume would be a bit expensive since it works on the whole pixel array of an image) and calculating the right position do draw it would characterize drawing work, or maybe not, since after that I may need to check for collision or something similar. Thinkig of it, seems like a silly question, but I would like some advice from more experienced developers. Where does does update ends and draw starts? Thanks in advance.

  • How to organize my site's file system properly?

    - by Wolfpack'08
    Doing some reading on Stack Overflow, I've found a lot of information suggesting that proper organization of a file system is crucial to a well-written web app. One of the key pieces of evidence is high-frequency references to "separation of concerns" in questions related to keeping programs organized. Now, I've found some information on organizing file systems (Filesystem Hierarchy Standard) from 2004. It raises only two concerns: first, the standard's a bit dated, so I believe it may be possible to do better given the changes in technology over the past 8 years; second, and most important, my application is very small compared to an entire Linux distro. I think that the file system should be organized very differently because of that. Here's what I'm looking at, currently: /scripts, /databases, /www -> /dev, /production -> login, router, admin pages, /sites -> content types, static pages /modules, /includes, /css, /media -> /module-specific-media

  • How do I reuse a state machine in a slightly different way?

    - by JoJo
    Problem I have a big state machine. The design requirements of the project have changed such that I need to re-use this state machine in another place. All the states remain the same in this new place, but a few states run slightly different stuff. What design pattern allows me to reuse this state machine? Motivation I am building a video player. It is modeled by a state machine with these states: stopped, loading, playing, paused, crashed, and some more... This video player needs to be used on two web pages. When the player crashes on the first page, it should show an error message below. If the player crashes on the second page, the error message should appear in the center of the video and pulsate a few times.

  • Is it possible to auto-mount sshfs

    - by Mark D
    Is it possible to auto-mount a remote FS using sshfs upon instantiating a proper VPN connection? Allow me to explain the scenario, I'm working remotely, to do that it helps if I can mount my home dir from a server in the office. To do that I need to vpn in. So within network manager I select the relevant VPN and connect. It connects but now I have to drop to the command line and mount my home dir on several machines. If I forget to do one machine my local dev environment isn't as efficient. I suppose I could write a quick bash script to do this but I'd rather get it running automatically when I connect.

  • Meaning of the free space indication in Deluge

    - by Tjae Beamon
    Recently I installed Ubuntu 12.0.4 using Wubi with my current Windows Vista. I have already installed all the 265 updates from the Ubuntu software center and downloaded Deluge from there. My hardrive is 80GB according to the disc usage analyzer. It also says 31.2 GB used and 47.8GB free. The confusion comes when I run Deluge. At the bottom it says 2.0GB free space. Is that 2.0GB just a size set from the torrent client and can be changed or am I limited to just that 2.0GB?

  • Why is Backbone.js a bad option in the Technology radar 2012 of thoughtworks?

    - by Cfontes
    In the latest Technology Radar 2012 they state that Backbone.js has pushed to far on it's MVC abstraction and say that Knockout.js or Angular.js should be used instead. I cannot get why they think that Backbone.js model is bad, for me it's just a way to create a standard so people can have some kind of roadmap to dev frontend JS without Spaghetti code. Also for me Angular and Knockout solve a different problem, I like both of them but having to code all MVC classes is something I think is kind of a rework. The thing is simple easy extendable and fast to learn, comes with a lot of goodies and is easy to combine with other Frameworks. (see Knockback.js) Can anybody tell me what made it so bad to their eyes ?

  • Half the time Linux drop into BusyBox; the rest of the time the boot happens normally

    - by JoBu1324
    I just installed Ubuntu x64 onto a USB3 Drive from a DVD, and half the time it appears to skip the grub menu and boots directly into BusyBox. Since the USB3 drive is an SSD, I ran through the full installation (installing on an ext4 partition, along side a 1GB boot partition at the start of the disk), skipping the swap partition. Part of the time that the Grub Menu does shows, it boots into BusyBox with an error: ALERT! /dev/disk/by-uuid/[uid] does not exist. Dropping to a shell! What could cause such an issue?

  • How to tell what part of a 3D cube was touched

    - by user2539517
    I am writing a rather simple android game and I am implementing Open GL to draw a 3D cube that spins upon the X, Y and Z axis and I need to know where the user has clicked on the texture of the cube. The texture is a simple square bitmap (100x100) that has a smaller square in the center. I need to know if the user touches the inner square. As well was tell which face of the cube the user touches. Does anyone know how this can be accomplished if not can anyone give some pseudo code on how to tell where the ray correlates to the texture? Or at least point me in the right direction. The textures of each face are like this: The code I am using is from: http://www3.ntu.edu.sg/home/ehchua/programming/android/Android_3D.html2.9 It is a port to android from Lesson 6 NeHe. Example 6a: Photo-Cube

  • Join me to register for the Summit

    - by Bill Graziano
    This year the Summit registration opens at 6PM on Sunday at the Seattle convention center.  Last year we had a dozen people hanging out, watching the twitter feed on the big monitor and catching up.  All we really needed was a bar and we’d have our own little party going. So this year I’m adding a bar.  I’ve arranged for a cash bar and some stand up tables.  I’m buying the first round for the first 40 or so people that come by.  Come by, register and say Hi.  I’d especially like to encourage first-time attendees to stop by.  This is a low key way to meet some people that will be at the conference.

  • Record and display Kinect audio and video via avconv

    I'm trying to record audio and video from a Kinect using avconv but I seem to have trouble specifying the right options. avconv -f video4linux2 -video_size 640x480 -c:v h264 -c:a ac3 -i /dev/video1 test.mp4 results in: avconv: /build/buildd/libav-extra-0.8.3ubuntu0.12.04.1/libav/libavutil/mathematics.c:79: av_rescale_rnd: Assertion `c > 0' failed. Aborted (core dumped) Cheese is perfectly happy recording the audio and video from the Kinect, so it's not a setup issue. For added fun, I also need to display the video at the same time.

  • Is it possible to power down my external via the eject button?

    - by beanaroo
    I'm trying to convert from Windows 7 to Ubuntu 12.10 with Gnome 3.6. Using the notification area's eject icon, I notice the partition is unmounted but the drive is still powered and spinning... I understand the latter can be taken care of by means of udisks --detach /dev/sdb I really don't want to have to run a command everytime I eject. Windows does the whole process when ejecting a medium via the systray. Is there a way I could add in the command to the eject button? Is there an appropriate place I could file a feature request? Little things like this are making it hard for me to swap back over to Linux. Thanks for the support!

  • how to find 3g modem signal strength with out AT commands?

    - by neckTwi
    when i try to find signal strength of my modem using AT+CSQ, the usb device is locked by the network manager. To find the signal strength with AT+CSQ i have to first disable network connection using #nmcli nm wwan off to unlock the device inode /dev/ttyUSBX. Is there any nmcli option to get signal strength or any other option? EDIT The gdbus object for NetworkManager don't have any method like getSignalStrength. Network manager is locking device file preventing to use AT commands. nm-applet was able to display signal strength in system tray. so there should be a way to get signal strength form network manager! nmcli is command line counter part of nm-applet. Can i get signal strength using nmcli? nothing about signal strength is mentioned in its man pages.

  • Waiting for Windows 8: A Long, Hot Summer

    - by andrewbrust
    Microsoft has revealed some things about Windows 8, and revealed a part of the developer story for new Windows 8 “tailored,” “immersive” applications.  In retrospect, very little was shared.  The bit that was revealed to us is that those applications can be developed using a combination of HTML 5 and JavaScript.  Not much else was said, except that additional details would be revealed at Microsoft’s //Build/ conference in Anaheim, California in September. This has left a lot of people in suspense, and it seems that suspended state is going to last all summer.  The problem, of course, is that in the absence of hard information, people fill the void with Speculation, Rumor and Gloom.  That’s a bit like Fear, Uncertainty and Doubt, except that it’s self-imposed by the Microsoft community and not planted by Microsoft’s competitors. This is a less-than-perfect situation.  Not only is it causing developers to worry about the value of their skill sets, but I am already hearing from consulting shops that customers are getting nervous too and, in extreme cases, opting for non-Microsoft tools for their projects as a result.  I’m also hearing from dev tool ISVs that sales have suffered as a result. It’s quite possible that the customers moving off .NET wanted to do so anyway and it’s also possible that dev tool ISVs are suffering slower sales this year due a slowed rate of economic recovery. Without hard information, tend to people interpret things negatively.  Actually, that’s the major point in all of this. While there is multitude of opinions about what the Windows 8 development platform will look like once fully revealed, there is an emerging consensus around one thing: it sure would help if Microsoft revealed more of its strategy…just enough to quash absurd rumors, stabilize the .NET ecosystem and get people to stay calm. We’ve had some reassurances thus far: there will be a Windows desktop mode; we’ll still have Windows Explorer, we’ll still run Office, we’ll still have a task bar, and all the skills and tools we use now will still work there.  But with reassurances like that…people still feel insecure.  Because telling us that Windows 8 will have what is essentially a “classic” mode sure makes it sound like today’s skill sets will soon be “classic” too…and then maybe they’ll just become obsolete. Humans find change scary; it’s natural.  And when left alone with their fears – because no one is saying anything to dispel them – people can go from frightened to paranoid, and can start to viewing things in a downright conspiratorial light.  It would be great if Microsoft stepped into the void now and told us what is coming – especially because whatever they tell us is bound to be at least a little better than what people think they are going to hear. I don’t know what the announcements will be, but I do have it on authority, from a number of sources, that Microsoft isn’t gong to talk until //Build/.  That means no news until September September 13th.  Nothing until after Labor Day.  You get zippo until after the Back-to-School sales are done. What to do?  Try not to let the dark voices of gloom and doom fill your head.  Even in the absence of answers, we still have some important facts: The .NET developer community is huge. Microsoft’s customers have major investments in .NET, and in .NET skills. Political infighting in Redmond might make for irrational decisions, but ultimately public companies can’t just alienate their advocates and piss off their customers.  Spite doesn’t trump fiduciary responsibility. The computing device markets are changing, software is changing, software business models are changing and developers are changing.  Microsoft has to keep up. The HTML + JavaScript community is huge too, and it includes many of the “changed” developers. Public companies can’t ignore new markets nor the popular standards that can help them enter those new markets.  Loyalty doesn’t trump fiduciary responsibility either. If Microsoft can appeal to new developers, then it should. If Microsoft can keep catering to its existing developers and customers -- not just through legacy support, but also through empowering futures -- then it probably will. You don’t have to shove your old friends out into the rain to make room for new ones; you can bring those new constituents in under a bigger tent.  I hope Microsoft will enlarge the tent, and I have trouble imagining why it would not.
