  • Gerrit, git and reviewing whole branch

    - by liori
    I'm now learning Gerrit (which is the first code review tool I use). Gerrit requires a reviewed change to consist of a single commit. My feature branch has about 10 commits. The gerrit-prefered way is to squash those 10 commits into a single one. However this way if the commit will be merged into the target branch, the internal history of that feature branch will be lost. For example, I won't be able to use git-bisect to bisect into those commits. Am I right? I am a little bit worried about this state of things. What is the rationale for this choice? Is there any way of doing this in Gerrit without losing history?

  • detecting when you are going to reach your hit limit for Google Analytics free account

    - by crmpicco
    I am a user of a free Google Analytics account and i'm slightly concerned that I may be approaching the 10,000,000 hit (Pageviews, Events etc) per month. Google state in their documentation: These limits apply to the Web Property / Property / Tracking ID. 10 million hits per month per property If you go over this limit, the Google Analytics team might contact you and ask you upgrade to Premium or implement client sampling to reduce the amount of data being sent to Google Analytics. However, I note that there is nothing to say that you can review or check up on your current usage for the month. I have administrator access to the Google Analytics account, but I see no feature that lets me check up on my monthly usage. I don't know if Google offer this, either by means of the admin interface or via their support channels - but it would certainly be a useful feature. Is there anyway for a free GA user to obtain this information?

  • unseen/unknown function definition in linux source

    - by Broncha
    Can any one please explain this piece of code I found in the linux kernel source. I see a lots of code like this in linux and minix kernel but dont seem to find what it does (even if C compilers support that kind of function definition) /* IRQs are disabled and uidhash_lock is held upon function entry. * IRQ state (as stored in flags) is restored and uidhash_lock released * upon function exit. */ static void free_user(struct user_struct *up, unsigned long flags) __releases(&uidhash_lock) { uid_hash_remove(up); spin_unlock_irqrestore(&uidhash_lock, flags); key_put(up->uid_keyring); key_put(up->session_keyring); kmem_cache_free(uid_cachep, up); } I cannot find out if this reference __releases(&uidhash_lock) before the parenthesis starts is allowed OR supported. (It sure is supported as it is in the linux kernel)

  • Atheros AR8132 Ethernet refuses to connect after suspend

    I'm having an issue where my ethernet card (Atheros Communications Inc. AR8132 Fast Ethernet (rev c0)) refuses to recognize when a network cable is plugged in after a suspend.

  • How do I know if my system is capable of playing 24bit/96kHz sound?

    - by Igor Zinov'yev
    Let me state for the record that I'm a total noob when it comes to Hi-Fi sound systems, but I am rather picky about the sound quality. Normally I listen to CD recordings ripped to FLAC in 16/44, but I have several albums that are also ripped from vinyls to FLAC in 24/96. But it seems that I can't tell the difference between 16-bit and 24-bit versions (except for some vinyl noises, of course). That can be due to several reasons: my equipment (onboard audio, monitor headphones) isn't good enough to make any difference, my system is not playing audio in 24-bit 96 kHz, I am physically unable to hear the difference. So here is my question, how do I tell if my system can play 24-bit sound with 96 or 192 kHz resolution? And if it can, how do I tell that it plays it instead of downsampling to 16-bit / 44 kHz? Also, what hardware (audio cards, amplifiers, etc.) would you recommend to play such recordings on Ubuntu?

  • Should I rely on externally-hosted services?

    - by Mattis
    I am wondering over the dangers / difficulties in using external services like Google Chart in my production state website. With external services I mean them that you can't download and host on your own server. (-) Potentially the Google service can be down when my site is up. (+) I don't have to develop those particular systems for new browser technologies, hopefully Google will do that for me. (-) Extra latency while my site fetch the data from the google servers. What else? Is it worth spending time and money to develop my own systems to be more in control of things?

  • Juju bootstrap fails with "Temporary failure in name resolution" using Amazon AWS

    - by Will
    I have followed the instructions over at https://juju.ubuntu.com/docs/config-aws.html to try and setup myself with a juju environment. It all seemed to setup alright. SSH keys, Gererate config, repository, adding access id and secret keys to environments.yaml file. Although my key file from aws IAM management console was called credentials.csv rather than rootkey, I couldn't find that link described in the documentation. When I give the command juju bootstrap in the testing page. It fails giving me the error: juju bootstrap ERROR Get https://s3-us-west-1.amazonaws.com/juju-gobblygookmynukmbersinhere/provider-state: lookup s3-us-west-1.amazonaws.com: Temporary failure in name resolution (note I just replaced my numbers for this posting my actual terminal has my numbers in. This is my first attempt at any ec2 work so I have gone in and created new IAM profiles. What have I done wrong? Any help would be great. I think I'm in over my head!

  • What liability concerns do advertising vendors raise, and how can I address them?

    - by Beofett
    One of the websites I administer wants to provide free advertising in the form of direct links to vendors at an event they are running. Up until now, there has been no advertising whatsoever on the site (or any of our other sites). The site is for a for-profit business. The idea of implicit endorsement of any vendors we advertise has been raised, which brought up the question of what we need to do, if anything, to protect ourselves from any potential problems such endorsement might create. I know that many sites have clauses in their Terms of Service that state that (in a nutshell) they are not responsible for any problems or grievances between the visitors to the site and any vendor advertised or linked. Are there other steps that a website typically takes when considering advertising, such as getting the advertiser to provide some sort of certification that their ad will not violate any trademarks or copyrighted material?

  • Fighting Cancer With Knowledge and Community: Oracle WebCenter at CPAC

    - by Brian Dirking
    There was a great article on CIO Magazine sometime back about how Cancer Treatment Centers of America are improving patient care with technology. And it is comforting to know you are getting state of the art care for you or your loved one when battling cancer. When patients and families take matters into their own hands, they often don't know where to turn to for information. The Canadian Partnership Against Cancer provides a one-stop shop that brings together the best information available in an easy to use website. Beyond finding information, CPAC provides an online community that can help extend knowledge, share experiences, and let people know they are not alone. You can hear more about this implementation from Mike Matthews of Deloitte in our upcoming online event, Transform Your Business by Connecting People, Processes, and Content. Mike is a partner at Deloitte and had first-hand experience in the CPAC implementation of Oracle WebCenter, which provides website publishing, search, and social community tools.

  • Is there a better approach to speech synthesis than text-to-speech for more natural output? [closed]

    - by Anne Nonimus
    We've all heard the output of text-to-speech systems, and for anything but very short phrases, it sounds very machine-like. The ultimate goal of speech synthesis systems is to pass a Turing test of hearing. Clearly, the state of the art in text-to-speech has much to improve. However, speech synthesis isn't restricted to just text-to-speech systems, and I'm wondering if other approaches have been tried with better success. In other words, has there been any work done (libraries, software, research papers, etc.) on natural speech synthesis other than text-to-speech systems?

  • library put in /usr/local/lib is not loaded

    - by IARI
    Let me state in advance: One might think this question would is for server fault, but I think is is Ubuntu (config) specific. In short: I have put libwkhtmltox.so in /usr/local/lib as stated in installation instructions linked below, but it appears the library is not loaded. I am trying to install php-wkhtmltox, a php extension for wkhtmltox on my local desktop (Ubuntu 12.04). I have extracted the source and changed to the corresponding directory. After running phpize, ./configure fails at checking for libwkhtmltox support... yes, shared not found configure: error: Please install libwkhtmltox I suspect the reason the library is not loaded is that the path is not checked!? how do I proceed? Here are instructions I followed: http://davidbomba.com/index.php/2011/08/04/php-wkhtmltox/ http://roundhere.net/journal/install-wkhtmltopdf-php-bindings/

  • What should be allowed inside getters and setters?

    - by Botond Balázs
    I got into an interesting internet argument about getter and setter methods and encapsulation. Someone said that all they should do is an assignment (setters) or a variable access (getters) to keep them "pure" and ensure encapsulation. Am I right that this would completely defeat the purpose of having getters and setters in the first place and validation and other logic (without strange side-effects of course) should be allowed? When should validation happen? When setting the value, inside the setter (to protect the object from ever entering an invalid state - my opinion) Before setting the value, outside the setter Inside the object, before each time the value is used Is a setter allowed to change the value (maybe convert a valid value to some canonical internal representation)?

  • Restoring projection matrix

    - by brainydexter
    I am learning to use FBOs and one of the things that I need to do when rendering something onto user defined FBO, I have to setup the projection, modelview and viewport for it. Once I am done rendering to the FBO, I need to restore these matrices. I found: glPushAttrib(GL_VIEWPORT_BIT); glPopAttrib(); to restore the viewport to its old state. Is there a way to restore the projection and modelview matrix to whatever it was earlier ? Tech: C++/OpenGL Thanks!

  • Conways Game of Life C#

    - by Darren Young
    Hi, Not sure if this is the correct place for this question or SO - mods please move if necessary. I am going to have a go at creating GoL over the weekend as a little test project : http://en.wikipedia.org/wiki/Conway's_Game_of_Life I understand the algorithm, however I just wanted to check regarding the implementation, from maybe somebody that has tried it. Essentially, my first (basic) implementation, will be a static grid at a set speed. If I understand correctly, these are the steps I will need: Initial seed Create 2d array with initial set up Foreach iteration, create temporary array, calculating each cells new state based on the Game of Life algorithm Assign temp array to proper array. Redraw grid from proper array. My concerns are over speed. When I am populating the grid from the array, would it simply be a case of looping through the array, assigning on or off to each grid cell and then redraw the grid? Am I on the correct path?
