  • How best to take a users signature online? (UK law orientated) [closed]

    - by Ben Griffiths
    Not sure if this is the best place to ask, but I can't seem to find any of the other SE sites that would fit better (unless there's a law one?) I'm building an application that will replace an existing paper based form, and this form would normally be signed by the person filling it in. Looking around, it's hard to find a good definitive resource to explain what I can and cannot accept as far as a signature goes. It looks like some UK government online forms accept just your name typed into a box, but I've also heard you should back up with an email - so that process would be type name into a box along with providing an email address, send out an email, then make them click a link within the email to finally complete the verification. Involving email seems very long winded and leaves the system open to spam filters blocking emails, forgotten emails that just sit in inbox's etc. So, does anyone have any knowledge in this department? Personally, I'd love to just get them to type their name into a box and be done with it!

  • No Sound from Shared Media

    - by Travis
    I have a shared media folder that I have all of my mp3's in. When I try to play them using Ubuntu, I get no sound, but the media player (Rhythmbox, Exaile, etc) display that they are playing the file, it looks like everything is playing but no sound. I have checked and rechecked the volume levels of the system and each application and I see no issues. If I move a file to the local drive, it plays just fine. I do sound checks while the file is playing and I get audio (front left, front right) from the test but not from the media file that I am playing. Any help would be greatly appreciated.

  • Animating isometric sprites

    - by Mike
    I'm having trouble coming up with a way to animate these 2D isometric sprites. The sprites are stored like this: < Game Folder Root /Assets/Sprites/< Sprite Name /< Sprite Animation /< Sprite Direction /< Frame Number .png So for example, /Assets/Sprites/Worker/Stand/North-East/01.png Sprite sheets aren't really viable for this type of animation. The example stand animation is 61 frames. 61 frames for all 8 directions alone is huge, but there's more then just a standing animation for each sprite. Creating an sf::Texture for every image and every frame seems like it will take up a lot of memory and be hard to keep track of that many images. Unloading the image and loading the next one every single frame seems like it will do a lot of unnecessary work. What's the best way to handle this?

  • Letting go of a project

    - by SkyOrg
    I've been the sole developer of a niche product for my company for nearly 6 years. I've grown quite attached to the project and I enjoy working on it. However, it was the decision of management to take the project out of my hands and move it under the wings of another team. Unfortunately, I'm having a hard time letting go of the project. I'm sad to see it leave my hands since I've put so much time into it and enjoyed working on it, but it also allows me to work on new things. I've even caught myself being a bit hostile to the other team, which is poor on my part. How can I convince myself to just let it go?

  • Where do I find display brightness controls in Lubuntu?

    - by dlanod
    I'm looking for a control to be able to change my standard display brightness in Lubuntu. I've tried How do I set default display brightness? but my system settings does not include a Screen option. I've also tried Power Manager, Monitor Settings and Screensaver under Preferences and couldn't spot anything to control this option. The function key mappings (this is a laptop) work to change the brightness, but I'm looking for a UI option as the laptop is physically set up to be mouse-based (keyboard is hard to access with how we've got it set up).

  • What is the worst programmer habit?

    - by 0x4a6f4672
    Many people get into programming because programming is fun. At least in the beginning. After some time doing it professionally, programming is no longer fun, often just hard work. Sometimes we develop bad habits along the way to make it fun again. Some bad habits of programmers are well known, for example the "I fix that in a second" habit, the "reinvent the wheel" practice or the "all code except mine is crap" attitude (which often leads to "I will re-write the entire program from scratch" syndrome). There are things which a programmer should never do. What is the worst programmer habit?

  • Is it save to configure "Shutdown" on "When laptop lid is closed" ?

    - by Takkat
    To setup a laptop owned by a complete PC novice any settings that may become hard to tackle remotely need to be avoided. The laptop will be administrated via SSH. One thing in my list are problems arising from improper wake-ups from suspend or hibernate as they may also affect network accessibility. This is why I thought setting up power management to "shutdown" on closing the laptop lid could be a good idea. However I am not sure if this is a safe way to do. What problems in addition to software not closing properly (and thus not saving their data) could I be faced if I proceeded as planned?

  • Do you accept counter offers when recruiting experienced programmers? [migrated]

    - by MathAttack
    It is VERY hard to find good experienced programmers. Generally if they're performing well, their employers don't want to let them go, and many don't have resumes, let alone resumes in circulation. Let's say you find one who for personal circumstances is available. And let's say you make them an offer that's fair within your salary structure. And let's say you get a modest counter. (5-10% of the total offer side) Do you accept the counter? Part of me says, "Programmers like this are so rare, why let a small sum get in the way of hiring them?" The other part says, "This precedent will set up an annual headache." Thoughts? I know it's not black and white.

  • how to really master a programming language

    - by cprogcr
    I know that learning a language, you can simply buy a book, follow the examples, and whenever possible try the exercises. But what I'm really looking is how to master the language once you've learned it. Now I know that experience is one major factor, but what about learning the internals of the language, what is the underlying structure, etc. There are articles out there saying read this book, read that book, make this game and that game. But to me this doesn't mean to master a language. I want to be able to read other people's code and understand it, no matter how hard that is. To understand when to use a function and when another, etc etc. The list could go on and on but I believe I've made the point. :) And finally, take whatever language as an example if needed, though best would be if C was taken as an example.

  • Images from remote source - is it possible or is it bad practice?

    - by user1620696
    I'm building a management system for websites and I had an idea related to image galleries. I'm not sure it's a good approach. Since image space needed is related to how many images a user might upload, I thought about using cloud services like DropBox, Mega, and Google Drive to store images and load then when needed. The obvious problem with this approach is that downloading the images from the 3rd party service would hamper the user experience due to the increased download times. Is there any way to save images belonging in an image gallery on remote source without hampering the user experience because of speed? Or is this approach really not a good practice?

  • Install vim offline

    - by rosemary
    I have Ubuntu 12.04.02 desktop in my college Lab of around 15 pcs with no internet connection. I used to install packages : sudo apt-get install vim It was just fine. But, now I want to install vim locally(i.e.,using a pendrive or CD drive). Where and how can I accomplish this,as I am new to it. Through googling, I could get some sites offering packages, but I have merely any idea on how to carry on: https://launchpad.net/ubuntu/precise/+source/vim http://www.ubuntuupdates.org/package/core/precise/main/base/vim http://pkgs.org/ubuntu-12.04/ubuntu-main-i386/vim-gnome_7.3.429-2ubuntu2_i386.deb.html What should I exactly download and where to store it in my ubuntu machine and run commands to properly install vim offline? Any word of advice is appreciated!

  • How Does Your Home Based Business Rank? Unlock the Mystery of Search Engine Optimization

    For many, the words "search engine optimization" (SEO) are simply confusing buzz words used by tech heads buried in the mysterious world of internet marketing. But listen up home based business owners, SEO can be a critical component of your marketing strategy, and when broken down to its basic level, SEO is merely a tool allowing you to use the various search engines such as Google or Yahoo! and others to gain visibility for your business and drive prospects to your website. SEO marketing is the process of improving the volume of traffic to a website through natural/organic (un-paid) search results. Unlike promoting your business via pay-per-click (PPC) strategies, which lists your business at the top of search engines such as Google or Yahoo! for a fee, SEO is a strategy with the goal of ensuring placement at the top without incurring expensive placement costs.

  • How can I rescue a Lubuntu install?

    - by Ghost
    Quick recap: I was having a problem with hibernation so I check and the linuxswap partition is missing, showing an "unknown" chunk of drive where it was. Happened before, booted to the liveCD and used Gparted to reformat that partition back to swap. Then I boot........F---- grub rescue... MBR took care of the problem, except that now I'm back to Windows only. EVERY guide out there makes me reinstall Lubuntu from scratch, a waste of time considering it will take me at least a day to reinstall everything there. Can't I just fix grub like I did with the win MBR?

  • Get system info from C program?

    - by Hamid
    I'm writing a little program in C that I want to use to output some system stats to my HD44780 16x2 character display. The system I'll be working with is a Debian ARM system and, although irrelevant, the display is on the GPIO header.(The system is a Raspberry Pi). As an initial (somewhat unambitious) attempt, I'd like to start with something simple like RAM and CPU usage (I'm new to C). I understand that if I make external command calls I need to fork() and execve() (or some equiv that will let me return the results), what I would like to know is how I go about getting the information I want in a nice clean format that I can use. Surely I will not have to call (for e.g); free -h And then use awk or similar to chop out the piece I want? There must be a cleaner way? The question should be seen as more of a generic, what is best practice for getting info about the system in C (the RAM/CPU usage are just an initial example).

  • How do I render terrain in a 2.5D perspective, like in the game Don't Starve?

    - by Hamdan
    I have experience in making 2D side scroller games such as Terraria, but now I want to challenge myself and make a game that has a 2.5D perspective. The game I am trying to mimic is Don't Starve. Right now my focus is on figuring out how to render the ground. I am having a hard time figuring out how they generated the ground, and then rendered it. The way I think they rendered the ground is by first painting the ground in some paint program, and then somehow manipulating that flat image so that it appears to have depth. I am completely confused by how you would actually render that type of terrain. I want the terrain to have the following features: Look like the terrain in Don't Starve, here is a video showing the terrain in Don't Starve The terrain will be flat, and the camera's angle and perspective will be fixed Any tips and hints will be appreciated, Thank you in advance. (I am working in Java, using the Light Weight Java Game Library (LWJGL).)

  • Update live USB distro?

    - by qubex
    I have Lubuntu 14.04 (and Ubuntu 14.04) on a pair of USB disks created by writing the img files to USB using dd on Mac OS X. Unfortunately these systems both have some known bugs (that have since been corrected) and lack certain important drivers for my system (which I have located online). How can I make the USB disks writable and how do I update the distribution upon them as one may do for a locally-installed system? And if I later proceed to install from these USB sticks onto a hard-drive, will they ‘carry’ the package and driver updates with them or will I have to start from scratch again? (I seem to remember from my ancient Windows XP days that such procedures were referred to as ’slipstreaming’ or somesuch on that side of the fence.) (No, I did not create a persistence partition when I created the sticks, because from Mac clearly that isn’t an option. And anyway, as I imperfectly understand it, the persistence partition is for user files and not for the modification of the system.)

  • Computer Freezes After GRUB

    - by paulmcg421
    Ok so I've just built my first computer and have got it running, here are the specs: Asus P8Z68-V PCI-E LX Motherboard, Intel Core i5-2500K, Patriot Memory 8GB (2 x 4GB), Viper Xtreme Series PC3-15000 1866MHz CL9 Division 2 Edition Memory (PXD38G1866ELK), Gigabyte ATI Radeon 6850 820MHz 1GB PCI-E HDMI OC Windforce 2x 500w Ezcool 24pin psu as standard. The only thing I haven't bought new is the hard drive, it's a 250gb that I removed from an Acer Aspire M5100 that I was using till now with no OS Problems. On start up it runs fine but is unresponsive after the GRUB menu disappears to load Ubuntu (Oneric Ocelot). The keyboard lights then turn off and the screen eventually returns that there is no signal. Is there anything that I could be missing from building? (This is my first attempt at building my own PC) Any input would be appreciated, thanks !

  • How to define a natural id in database?

    - by gcc
    There are a lot of manuals. I am trying to create an database to hold information of these documents. But, there is a small problem. How can I give meaningful id to the manuals? Are there any standard or logic behind the giving meaningful id to the documents? If there is no standard, can you tell me how I should do that? example: table : manual id | manual name EDIT: Not Meaningful ID 1 or M1 or foo 2 C2 bar 3 P123 name ... ... ... (i) (ii) (iii) (i) Not meaningful for me because if some item deleted, there can be gap. ex 1 33 100. (ii) random character can be confusing when one try to give a name to new manual (iii) Why giving name is not preferred is because finding a name to the manual as ID is hard after 500 manuals. Meaningful : New ID * Can be easily produced even if after 1000 manuals * Should not be so complicated

  • Find angle for projectile to meet target in parabolic arc

    - by TheBroodian
    I'm making a thing that launches projectiles in 2D. Its projectiles are fired with a set initial velocity, and are only affected by gravity. Assuming that its target is within range, and that there aren't any obstacles, how would my thing find the appropriate angle at which to launch its projectile (in radians)? The equation for this is found here: Wikipedia: Angle Required to Hit Coordinate Sadly, I'm not a physicist (a.k.a. can't read smart people math) and am having a hard time reading its breakdown. If not only for the sake of anybody else that might read this other than myself, would anybody be kind enough to break the equation down into baby words please?
