• I want to record a screencast of a processing sketch

  - by nathanvda

  I have a created a music visualisation using Processing. I now want to convert that to a video, and the least obtrusive way I could think of is to record a screencast. I figured exporting Processing to video including audio, from within Processing itself, on ubuntu seemed an unsolved issue. Very hard and also could cause timing sync issues (since the music keeps running while images are captured). So move on to the screencast method. Dead-easy, I figured. But I was wrong. First hurdle was to find a way to record the sound from the audio (and not the mic). I did find a tutorial for that here. In short: use gtk-recordmydesktop and pulse audio. But, apparently, what happens: Processing does not use ALSA. When the sound is playing, it does not appear in the Pulse Audio mixer. How can I record the audio now?

• How can I improve Eclipse's user Interface to get rid of the excessive padding and spacing?

  - by csilk

  Eclipse Juno (historical versions too) has too much padding applied to the tabs and borders. This makes it hard to work with multiple project folders, especially ones containing multiple packages and nested directories, due to an overall lack of space. This only appears to be an issue on Linux. Windows and OSX both have less padding which vastly improves the user experience. This issue affects my 15.4 inch laptop with a resolution of 1366 x 768. I'm not sure if this issue affects larger resolutions. Is there a way to change the padding and make the whole application look a little more compact / smaller? I've attached a screenshot of an empty Eclipse project in Eclipse. I'll add an OSX screenshot tomorrow for comparison.

• 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?

• 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!

• 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).

• Please Help to bring back power to my machine

  - by Acess Denied

  I Have a samsung N150plus netbook That I have been using for a while now. I left it on and plugged to a wall outlet and went to bed. I dual boot ubuntu and win7. I tried to update the win7 to sp1 and I dozed off. I woke up and saw the machine has been booted to ubuntu and logged in as guest, which translate to mean one of my room mates have tried to use the machine and they all have denied using my machine. I tried to reboot to windows and then it appears to have no cpu, hard disk and cpu fan activity. only one led seems to come on when i plug it in. its only the led that indicate the machine is powered on powers steadily. I really cant afford to buy a new machine now and I need the machine to complete my last project in school for my last year. Help Please

• Default save directory for gnome-screenshot?

  - by trent

  Are there any sort of configuration options for specifying the default save location for gnome-screenshot, or is this hard-coded into the source code? It used to be ~/Desktop, which seems to have changed to ~/Pictures (in 12.04). The only possible solution I've seen is about Setting the default name (as it includes time stamp information now instead of simply Screenshot#), but that solution doesn't really seem ideal to me. Also, this post suggested that the last save location is remembered the next time you take a screenshot, but in my experience, this doesn't seem to be the case. And in any case, following on from that, that entry in gconf-editor doesn't even seem to accurately reflect the last location, so more than likely an entry related to an older version of gnome-screenshot.

• Ubuntu Wubi Booting Problem

  - by D3s7

  i have a problem with my Ubuntu 12.04 Wubi installation, sometimes when booting, the computer will get to the purple screen without the Ubuntu logo, then will go to a black screen and then lots of white saccaged colors will appear and i will be taken to the login page. But sometimes, it just get stuck on the black screen and does nothing and i have to hard shutdown and retry it until it works. What may cause this problem and why? I can shutdown correctly. Thanks for helping. Edit: RADEON HD 7650M Graphic card with latest available Drivers on amd's driver download site (fglrx drivers caused shutdown problems so i removed them). Screen resolution is 1600x900.

• 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.

• 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?

• 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.

• 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.)

• 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?

• How do I increase the touchpad sensitivity on Acer Aspire One 532h?

  - by Yossi Farjoun

  I got a cheap netbook and put ubuntu on it without even booting into the windows it came with. I am now slightly regretting it since the trackpad is very annoying, it only registers when I press quite hard on it, and even then the motion is so slow that I must drag me poor finger 3 times to get the pointer to move up or down that tiny screen. OK. enough rant. now business: I went into the setting and increase sensitivity and acceleration to high. No difference. the behaviour did not change at all. So now my questions are: Is this a hardware problem? Is there a program I can run to see what input the trackpad is receiving? so I know if it can, in theory, read the light touch and not only the heavy, sandpaper-your-fingertips-off touch? is there some manual setting that the system might not be setting correctly and which I could change from the terminal?

• How to sell Agile development to clients [on hold]

  - by Sander Marechal

  Our development shop would really like to do more agile projects but we have a problem getting clients on board. Many clients want a budget and a deadline. It's hard to sell a client on an agile project when our competitors do come up with waterfall-based fixed deadlines and fixed prices. We know their fixed numbers are bad, but the client doesn't know that. So, we end up looking bad to the client because we can't fix the price or a deadline but our competitors can. So, how can you get your sales force to successfully sell a project that uses agile development methods, or a product that is developed using such methods? All the information I found seems to focus on project management and developers.

• 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?

• 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 !

• 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!

• Tips or techniques to use when you don't know how to code something?

  - by janoChen

  I have a background as UI designer. And I realized that it is a bit hard for me to write a pieces of logic. Sometimes I get it right, but most of the time, I end up with something hacky (and it usually takes a lot of time). And is not that I don't like programming, in fact, I'm starting to like it as much as design. It's just that sometimes I think that I'm better at dealing with colors an shapes, rather than numbers and logic (but I want to change that). What I usually do is to search the solution on the Internet, copy the example, and insert it into my app (I know this is not a very good practice). I've heard that one tip was to write the logic in common English as comment before writing the actual code. What other tips and techniques I can use?

• Dealing with engineers that frequently leave their jobs [closed]

  - by ??? Shengyuan Lu

  My friend is a project manager for a software company. The most frustrating thing for him is that his engineers frequently leave their jobs. The company works hard to recruit new engineers, transfer projects, and keep a stable quality product. When people leave, it drives my friend crazy. These engineers are quite young and ambitious, and they want higher salaries and better positions. The big boss only thinks about it in financial terms, and his theory is that “three newbies are always better than one veteran” (which, as an experienced engineer, I know is wrong). My friend hates that theory. Any advice for him?

• 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?
