• Creating basic ACPI event makes the system unusably slow

  - by skerit

  I want to change a few settings on my laptop when I switch to battery power. I created a new event in /etc/acpi/events/cust-battery and it looks like this: event=battery action=/home/skerit/power.sh I put a simple command in the power.sh file: echo This is a test >> /home/skerit/powertest Now, when I tail this file it shows "This is a test" 4-5 times upon switching to battery power. However, the system becomes totally unstable. It slows down significantly. I can't change anything in the terminal. The terminal and certain parts of the screen (like the gnome system monitor applet) go blank from time to time. What can be the cause of that? It's a simple echo that gets executed a few times!

• Importance of frequency of keywords for SEO [closed]

  - by Calle

  Possible Duplicate: keyword stuffing in SEO I've seen a few posts on here and elsewhere that talk about the amount of unique keywords used, or aimed, for in a text. But how important is the frequency of keywords for SEO optimized copy, the higher the better? Is there a certain percentage to aim at? For example, I currently have copy aimed for a specific keyword. The rate of this keyword is that it makes up 2% of all words. Is this too low? Too high? The higher the better?

• How should I store a Game Database on Android?

  - by Liam

  I'm looking at creating a game for Android and while I have most of the ins and outs worked out, the one thing I'm struggling with is how to store data for the game. Ultimately, the game will be based off of a lot of pre-defined data and statistics so the obvious choice to me would be something like SQLite, but as I'm pretty new to the realm of Android and Game Development, I'm not 100% certain if this is the right route to follow. The data will be general pre-defined data as well as player data (along the lines of careers stats - what place finished, etc). I was wondering if there was a better/best practice solution that wasn't SQLite and that would provide said functionality and if so, could you point me in the right direction?

• Equation / formula to determine an objects position on an ellipitcal path

  - by David Murphy

  I'm making a space game, as such I need objects to follow an elliptical path (orbit). I've worked out how to calculate all the important aspects of my orbits, the only remaining thing is how to have an object follow it. My Orbit class contains the major, minor (and by extension semi-major,semi-minor) lengths. The focii radius, area and circumference even. What is the equation to determine an objects x/y position (only need 2D) on an ellipse with a certain speed after a period of time. Basically, every frame I want to update the position based on the amount of elapsed time. I would like to have the speed along the path speed up and slow down according to the distance from the object it's orbiting, but not sure how to factor this in to the above given that at any point in time the speed has changed from it's previous speed. EDIT I can't answer my own question. But I found the question and answer is already on stackexchange: Kepler orbit : get position on the orbit over time

• What is the traditional way to maintain extensibility in a database-driven application like this?

  - by Jsess

  I'm working on a simple application for a game in Java that allows a user to record whether they have collected a given item and how much experience it contains. This will work for multiple item types (weapons, armor) and each will have its own tab with a list of all items that qualify under it. Making changes as new types are added is not such a big deal (if a clothing slot is added, for instance), but new items are added to the game all the time in biweekly patches, and I'm not sure what the traditional/customary way to make sure the application is user-extensible without requiring me to would be. Whether that would be adding a configuration menu that allows users to add news items (new rows to the local SQLite database) or a text file with something similar, but I'm certain there's a well-accepted way to do this that I'm not aware of. I'm new to databases and ignorant of the solution, so what's the professional/futureproof way to do this?

• Scan-Line Z-Buffering Dilemma

  - by Belgin

  I have a set of vertices in 3D space, and for each I retain the following information: Its 3D coordinates (x, y, z). A list of pointers to some of the other vertices with which it's connected by edges. Right now, I'm doing perspective projection with the projecting plane being XY and the eye placed somewhere at (0, 0, d), with d < 0. By doing Z-Buffering, I need to find the depth of the point of a polygon (they're all planar) which corresponds to a certain pixel on the screen so I can hide the surfaces that are not visible. My questions are the following: How do I determine to which polygon does a pixel belong to so I could use the formula of the plane which contains the polygon to find the Z-coordinate? Are my data structures correct? Do I need to store something else entirely in order for this to work? I'm just projecting the vertices onto the projection plane and joining them with lines based on the pointer lists.

• Should I use nodindex, follow or rel canonical?

  - by webmasters

  I have a site that lists offers, promotions from other websites. Since the offers expire rather quickly I don't save them into my database. I see no point in having a page from 2010 about 30% discount on a certain brand of shoes which isn't availabe anymore. A visitor enters my website; He clicks on the "shoes" category; http://www.mysite.com/shoes/ Here he sees 20 available promotions from different online stores. He clicks on a promotion and gets to a page like this: http://www.mysite.com/shoes/promotions/prada Questions: I use the template promotions.php and list all the promotions. /promotions/prada/ /promotions/otherbrand/ .... What I do is use "noindex, follow" for the links. Is that a good idea? Or should I use rel="canonical" for the promotion page? How do you advise me to handle this from the SEO point of view?

• how to "think in templates", i.e. how to know that a problem can be solved using templates and how to adapt to it?

  - by sap

  I decided to improve my knowledge of template meta-programming, i know the syntax and rules and been playing with counteless examples from online resources. i understand how powerfull templates can be and how much compile time optimization they can provide but i still cant "think in templates", that is, i cant seem to know by myself if a certain problem could best be solved with templates (instead of something else) and if it can, how to adapt that problem to templates. so what im asking is, is there some kind of online resource or maybe book that teaches how to identify problems that could best be solved with templates and how to adapt that problem. basically i want to learn to "think in templates". already asked on stackoverflow but once again people just redirected me to resources on how to use templates, when im really asking is how to know when to use template meta-programming and how to adapt that problem to templates. thanks in advance.

• Good practices in screen states management?

  - by DevilWithin

  I wonder what are the best ways to organize different screens in a game? I am thinking of it like this: Inheriting a base State class, and overriding update and render methods, to handle the current screen. Then, under certain events a StateManager is able to activate another Screen State, and the game screen changes as only the current State is rendered. On the activation of a new screen, effects like fading could be added, and also the same goes for its deactivation. This way a flow of screen could be made. By saying when A ends, B starts, allowing for complex animations etc. Toughts?

• Why are there different programming languages [closed]

  - by Velizar Hristov

  I'm not asking about the usefulness of the languages that do exist already: I already know, and agree, that different languages are better for different purposes. However, why don't they just have a single language that can do it all? Why, when C# was created, they didn't keep everything from C and C++ and just add a few things, so that it can be used as both a low-level and high-level language? I see no harm in adding all kinds of commands to a single language that would allow it to be good for everything, and even eliminate the need for all other languages. Someone from another thread said that if there's a flaw in a certain language, its successor might not have it. However, why don't we just update that language to remove the flaw, and/or add anything that's missing? Arrays are different in Java and C#, but why not have them both, just use different commands for them? And so on...

• Is Unity's Random seeded automatically?

  - by Lohoris

  I seem to recall Unity's Random is automatically seeded; checking the documentation it doesn't say it outright, but a certain interpretation of their words might seem to imply it. The seed is normally set from some arbitrary value like the system clock before the random number functions are used. This prevents the same run of values from occurring each time a game is played and thus avoids predictable gameplay. However, it is sometimes useful to produce the same run of pseudo-random values on demand by setting the seed yourself. (emphasis added)

• Requirement, architecture data capture tool

  - by Deno

  Are there any tools available for the following use case: I am planning to write a complex application and now I just know about the basic functional requirments. I am refining the functionality with more and more details. I am also writing down how to implement this in software architecture perspective. I am in a situation where there are multiple ways implement a certain functionality and based on the selected approach, other parts of the program will also change. At this moment, I don't want to decide on the approach to use, I just want to list down all the options, present to a wider audience and get it finalized. Are there any standard software tools to do this? I know I can use MS excel or some mind mapper tools, but just thinking of some standard tools (not just for programmers, but for managers and other) availability Thanks, Den

• Restricting access to sites

  - by Paul

  I'm having some problems configuring my local proxy server so that it would restrict access to certain websites. The proxy server I'm using is Squid; I edited its configuration file found in /etc/squid/squid.conf to include the following: acl wikipedia dstdomain .wikipedia.org http_access deny wikipedia I tried to redirect elinks to use Squid. According to Squid's config file, it listens to port 3128, so in /etc/elinks/elinks.conf I added the following: set protocol.http.proxy.host = "localhost:3128" I also restarted Squid with sudo /etc/init.d/squid restart, but I can still access the banned websites using Elinks. What did I do wrong?

• Adding a list of "recent articles" affects SEO

  - by Groo

  We have a site which has a sidebar with sections (or "widgets" if you like) showing stuff like "Recent Articles", "Other Articles by this User", "Similar Articles" etc. The issue is, Google seems to take these links very seriously. In fact, if I have only a single article which is closely related to a certain phrase (and several other pages link to it in their sidebars), when I do a Google search, it lists all those other pages highlighting that one link to the page that should actually be the most relevant one. And these pages don't even mention the phrase anywhere else. It there a common approach with adding these sidebar links? For example, I might add them through ajax after the page is loaded, but then crawlers will have harder time finding them?

• Earliest use of Comments as Semantically Meaningful Things in a Program?

  - by Alan Storm

  In certain corners of the PHP meta-programming world, it's become fashionable to use PHPDoc comments as a mechanism for providing semantically meaningful information to a program. That is, other code will parse the doc blocks and do something significant with the information encoded in those comments. Doctrine's annotations and code generation are an example of this. What's the earliest (or some early) use of this technique? I have vague memories of some early java Design by Contract implementations doing similar things, but I'm not sure of those folks were inventing the technique, or if they got it from somewhere. Mainly asking so I can provide some historical context for PHP developers who haven't come across the technique before, and are distrustful of it because it seems a little crazy pants.

• 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?

• How can I have a Bluetooth Keyboard Auto-Connect at Startup?

  - by Grant

  I have a bluetooth keyboard for my HTPC. I pair it with my computer via bluetooth, and it works fine. However, when I turn off the keyboard or my computer, it has to connect again (which requires me entering a passcode on the computer and keyboard) when I turn them back on. I've looked through many forums and through that I have found that I'm missing some seemingly vital bluetooth files: /etc/default/bluetooth /etc/init.d/bluetooth /etc/bluetooth/hcid.conf In the instructions that I've found online so far, I must change certain lines in any of these files. I am unable to, since they do not exist. Am I missing a dependency or something? I've also tried installing Blueman but that didn't help at all. I'm running Ubuntu 10.10 (Maverick). Original post: http://ubuntuforums.org/showthread.php?t=1643386&highlight=bluetooth

• Getting a job at Google/Microsoft companies [on hold]

  - by user2498079

  Alot of people say it is very hard to get a job at Google/Microsoft. Due to insufficient number of jobs, there is very tough competition for fresh graduates to get a job at the worthy company. I have read certain articles which encourage fresh graduates to have good projects (Programming projects), Focus on Accomplishments or have a good reputation on websites like this one. So my question is what kind of programming projects & accomplishments help in getting job at Google/Microsoft. There are alot of other factors like communication skills & leadership etc but this is not the main concern here. Regards

• how to remap Ctrl to Escape if pressed and released on its own

  - by psvm

  I want to remap Control, so that: A. If it is pressed and released with no other key, it acts as Escape. B. If it is pressed & held together with another key, it acts as Control (no change in behavior in this case). I'm aware of How do I remap certain keys?, so I suspect it may be done with xmodmap. But that answer does not explain how to map the modifier keys. I looked into the examples and grammar sections of the xmodmap manpage, but they do not explain that. The answer in Remapping Caps Lock to Control and Escape (not the usual way) mention that it is not possible to do that to CapsLock, since it is a Lock key, but I hope this may be possible to do it with Control which is a mod key. A solution with something different than xmodmap will also be accepted. (I'm running Xmonad in Ubuntu 12.04, so perhaps there is a way to set this up in xmonad.hs?)

• What are some potential issues in blocking all incoming requests from the Amazon cloud?

  - by ElHaix

  Recently I, along with the rest of the world, have seen a significant increase in what appears to be scraping from Amazon AWS-related sources. So simply put, I blocked all incoming requests from the Amazon cloud for our hosted application. I know that some good services/bots are now hosted on the cloud, and I'm wondering if certain IP addresses should be allowed, as they may gather data that would in the end benefit our site's SEO rankings? -- UPDATE -- I added a feature to block requests from the following hosts: Amazon Softlayer ServerDeals GigAvenue Since then, I have seen my network traffic decrease (monitored by network out bytes). Average operation is around 10,000,000 bytes. You can see where last week I was not blocking, then started blocking. I've since removed the blocks and will see what the outcome is.

• Ubuntu stops letting wired or wireless mice click through after a short while

  - by Jonathan Chan

  Hi! I have a very confusing problem that renders Ubuntu near unusable. Whenever I try to use any wired or wireless mouse with my Ubuntu 10.10 install, clicks stop going through - often times, this blockage of clicks happens in less than a minute. Sometimes no clicks are accepted, other times, clicks are accepted in certain windows and denied in others. The end result is the same, and I am forced to resort to using the keyboard to navigate. If anyone could help me resolve this problem, I would be very appreciative, as it would finally allow me to try Ubuntu. Thanks!

• Attempting to GREP details of a Java error

  - by BOMEz

  I'm running Ubuntu 11 and I'm having some issues with grep. I have a shell script (see below) which essentially checks if a certain Java program of mine is running, if not it runs it. That part works out great! If my Java application throws any kind of exception however I would like to capture that information and email it to myself. How can I go about checking to see if the call to java -jar /bin/MyApp.jar fails? I tried piping it to grep, but that doesn't seem to work. Below is the full script that I've written: #Check if MyApp.jar is running, if not run it. if [ $(ps aux | grep 'java' | grep -v grep | wc -l | tr -s "\n") -eq 0 ] then echo "PacketCapture Starting...\n" java -jar /bin/MyApp.jar echo "PacketCapture Started.\n" else echo "PacketCapture already running.\n" fi

• Launchpad fails to build a package for my PPA

  - by AZorin

  I'm trying to build a package on Launchpad's Debian build system for PPAs but I'm having some issues with a certain package. The package I'm trying to build (zorin-xwinwrap) contains a source C file which I'm trying to get to compile and build on Launchpad's server so that it would install and work on 32 bit (i386) and 64 bit (amd64) systems. Unfortunately I keep on getting an Error code 2 with the debian/rules file and I have no clue how to fix this issue. The following link is the source package of the software I'm trying to add to my PPA: http://goo.gl/GjZvd The following link is the buildlog for the failed package on Launchpad: http://goo.gl/6A2rQ I would greatly appreciate any suggestions if anyone may have any. Thank you for your time.

• Is there a name for this use of the State design pattern?

  - by Chris C

  I'm looking to see if there is a particular name for this style of programming a certain kind of behavior into a program. Said program runs in real time, in an update loop, and the program uses the State design pattern to do some work, but it's the specific way it does the work that I want to know about. Here's how it's used. - Object Foo constructed, with concrete StateA object in it - First loop runs --- Foo.Run function calls StateA.Bar --- in StateA.Bar replace Foo's state to StateB - Second loop runs --- Foo.Run calls StateB.Bar - Third loop runs --- Foo.Run calls StateB.Bar - Fourth loop --- etc. So in short, Foo doesn't have an explicit Initialize function. It will just have Run, but Run will do something unique in the first frame to initialize something for Foo and then replace it with a different action that will repeat in all the frames following it- thus not needing to check if Foo's already initialized. It's just a "press start and go" action. What would you call implementing this type of behavior?
