• Using Google App Engine to Perform World Updates vs an Authoritative Server

  - by Error 454

  I am considering different game server architectures that use GAE. The types of games I am considering are turn-based where the world status would need to be updated about once per minute. I am looking for an answer that persuades me to either perform the world update on the google servers OR an authoritative server that syncs with the datastore. The main goal here would be to minimize GAE daily quotas. For some rough numbers, I am assuming 10,000 entities requiring updates. Each entity update would require: Reading 5 private entity variables (fetched from datastore) Fetching as many as 20 static variables (from datastore or persisted in server memory) Writing 5 entity variables Clients of the game would authenticate and set state directly against GAE as well as pull the latest world state from GAE. Running the update on GAE would consist of a cron job launched every minute. This would update all of the entities and save the results to the datastore. This would be more CPU intensive for GAE. Running the update on an authoritative server would consist of fetching entity data from the GAE datastore, calculating the new entity states and pushing the new state variables back to the datastore. This would be more bandwidth intensive for the datastore.

• Lubuntu 12.04 on Acer laptop boots to blank blue screen

  - by WGCman

  My previous question on this was closed, but I am posting it again as the solution which my son eventually found may assist other users of the forum, or someone may be able to tweak the solution to improve the performance. Having installed Kubuntu 12.04.01 from a live USB onto my desktop, I wanted to do the same on my laptop, an Acer Aspire 1362 Laptop, which has 256MB RAM (actually 512 "on the box", but a good deal can be borrowed by the graphics!). I found Kubuntu wouldn't run on so little memory but downloaded: Lubuntu-12.04-alternate-i386.iso, which I understood was light enough to go. The laptop has one internal 40GB Toshiba hard drive divided into 3 partitions: C,19GB with Windows XP, Windows program files and some data, D, 19GB mostly data, and a small 2GB partition with some Acer software, which XP can't normally “see”. I transferred most of the contents of D to a memory stick, leaving 16GB free for Lubuntu. I did not want to dump XP yet, though it is painfully slow. I installed Lubuntu from then USB stick, accepting the default answers to most of the questions. The D: partition was further partitioned into a 500MB boot partition, 10GB for Linux, 2GB Swap and 6GB for data shareable between Linux and Windows. I had no error messages during installation, rebooted, was offered the choice of Ubuntu or XP, and selected the former. After a few minutes, I get a dark blue screen announcing Lubuntu with five dots underneath which lighten in turn. Eventually the lights stopped, and whatever I try the screen remains blank apart from “Lubuntu” I tried several solutions suggested on the forum for “identical” questions but without success.

• How can I assign actions to all my mouse buttons?

  - by Torben Gundtofte-Bruun

  I have a mouse with lots of buttons, but it's not a mainstream make like Logitech. For Windows, I have a driver that lets me assign actions like close-window (Ctrl+W) or next-tab (Ctrl+Tab), but I don't have a Linux driver. Since Linux is so flexible, I thought perhaps there is a general way to do this, regardless of brand? Update: Based on input from Cyrex, I installed and ran sudo apt-get install btnx which found several but not all mouse buttons. Found: left, right, wheel, wheelclick, thumb fwd, thumb back. Not found: wheel left, wheel right, thumb middle button. Vendor ID is 0x04d9, Model ID is 0xa015. Update 2: In SystemPrefsMouse there's a lightbulb icon for testing double-click speed. Every working button can turn the bulb on&off, but the missing buttons can't. It would seem that Ubuntu isn't aware of these buttons and thus doesn't register their clicks. I guess I need to hunt for a driver, though a mainstream mouse is probably the easier way.

• Defining a function that is both a generator and recursive [on hold]

  - by user96454

  I am new to python, so this code might not necessarily be clean, it's just for learning purposes. I had the idea of writing this function that would display the tree down the specified path. Then, i added the global variable number_of_py to count how many python files were in that tree. That worked as well. Finally, i decided to turn the whole thing into a generator, but the recursion breaks. My understanding of generators is that once next() is called python just executes the body of the function and "yields" a value until we hit the end of the body. Can someone explain why this doesn't work? Thanks. import os from sys import argv script, path = argv number_of_py = 0 lines_of_code = 0 def list_files(directory, key=''): global number_of_py files = os.listdir(directory) for f in files: real_path = os.path.join(directory, f) if os.path.isdir(real_path): list_files(real_path, key=key+' ') else: if real_path.split('.')[-1] == 'py': number_of_py += 1 with open(real_path) as g: yield len(g.read()) print key+real_path for i in list_files(argv[1]): lines_of_code += i print 'total number of lines of code: %d' % lines_of_code print 'total number of py files: %d' % number_of_py

• Lexmark E240 printing issues

  - by NoamH

  I have Lexmark E240 laser printer. I have been using it with 12.04 (32bit) for 2 years with no significant issues. Since lexmark does not support this printer on linux, I used alternatives drivers that were suggested by the community, such as HP-lasterjet, E238, generic PS, etc. They all worked fine, more or less. After upgrading to 14.04 (64bit fresh install) I tried to configure the printer as before, but now I have problems. The test page is ok, but when printing, most of the times, the first page in the document will be printed very partially and in 300% zoom. Next page might be ok. If I turn off the printer and back on, the first page might be ok, but in the next print job, it will be broken again. I used all the above printer options. Same results. I did NOT install the lexmark drivers since they are intended for 12.04 and the package manager report that it is in "bad quality" (don't know why). Does anyone has any experience with this printer in 14.04 64bit ?

• Ubuntu 12.04LTS stuck at login mouse and keyboard not responding

  - by user169954

  I have Ubuntu 12.04LTS installed on a dual-booted machine (i5 dual core 8G ram) and it's been working fine, but today for some reason when I logged out and tried to log back in it is stuck at the login page, i.e. the mouse and the keyboard are not responding. The mouse is stuck at the top left corner of my screen, and I can do nothing but to turn the machine off. (I have been using logitech wireless mouse and keyboard.) I can not access the virtual console (Alt-F1 or Cntrl-Alt-F1) either! Here is what I have tried so far: Verified it is not a H/W problem since the mouse and keyboard work fine with windows7 Booted with ubuntu installation dvd and ran trial mode and mouse and keyboard worked fine. Tried bypassing the login screen by booting into recovery mode and editing tty1.conf, but to no avail. I moved .Xauthority .profile and .bashrc from my $HOME to another location so my login would proceed completely by system defaults. But this did not help From recovery mode commandline used to dpkg-reconfigure to switch between gdm and lightgdm. This did not help either. By the way, when in recovery mode as root from command line I mount the filesystem, all apps work fine. Python is Ok, octave is ok, vi is ok etc. I have a feeling if I could only bypass the login screen, and automatically get into the desktop, I will be ok. But I haven't been able to accomplish this either. I desperately need help please. Thank you in advance. Update: So I tried to switch to lightdm by dpkg-configure lightdm. This at least brings me up to the classical linux commandline login prompt but without a gui. Should I install startx? Should I install ubuntu-desktop?

• Shooting Print Quality Pictures with a Camera Phone [Video]

  - by Jason Fitzpatrick

  Camera phones get a lot of grief for being underpowered but in this video tutorial the crew at SLR Lounge shows how basic technique and a good eye overcome all. Last year over at the photo blog FStoppers they put together a video showing off how you could use the iPhone as a fashion camera–essentially arguing that the camera wasn’t as important as the photographer. A lot of people said “Well yeah, but you had professional models and thousands of dollars in lighting equipment!” in reaction to the video. In turn the crew at SLR Lounge decided to make their own video showing that using only an iPhone camera and two reflectors (as well as an attractive but informal model). It of course helps to have some side kicks to help hold up your reflectors but the point still stands about modern camera phones being perfectly capable of good photos.

• After upgrading to trusty, ALSA midi connection (aconnect) doesn't seem to work right

  - by SougonNaTakumi

  Previously in kubuntu 13.10 I was able to open vmpk or plug in a midi keyboard, and provided that TiMidity was running in server mode, I could run aconnect [keyboard port (129:0 for vmpk)] 14:0 aconnect 14:0 128:0 and I could play the keyboard and get sound. But now, a while after upgrading to trusty, I tried to do that, and didn't get any sound. TiMidity itself still plays files fine, but if I try to play them with aplaymidi, I still just get silence. Oddly, the midi files are clearly being read. When I ran (where 130:0 was vmpk's input port) aplaymidi -p 130:0 ~/path/to/midi.mid vmpk was highlighting notes on the piano as if it were playing the midi. One time I tried this, TiMidity (?) very briefly played a fraction of a second of the first chord of my song before everything went silent and vmpk just highlighted the first voice on the keyboard as usual. Now the weirdest part of this is that probably about 40% of the time, when I've played at least one note with either aplaymidi or vmpk, when I run aconnect -x I get a sudden burst of a note or chord from my speakers (that is, if I played one note, I get a note; if I played multiple sequential notes, they turn into a chord), as if the notes were being queued up but not being played and that somehow liberated them. I have no idea what's going on there. A little while ago I remember having a problem with Audacity playing wav files sped up and also locking up if I tried to pause it, which it stopped doing when I set the audio devices to the actual audio devices rather than pulse. But now when I checked again, it's doing the opposite: it won't play audio at all and/or acts weirdly if I don't set the audio devices to pulse, and either way will very occasionally randomly do the speeding up thing regardless. Oddly in the midst of what's looking like a pretty screwed up sound system, sound in VLC and Firefox has been working fine and if I play a wav file with aplay ~/path/to/sound.wav that works fine too. Any idea what I could do to figure out what's wrong with ALSA and/or fix it?

• How to implement child-parent aggregation link in C++?

  - by Giorgio

  Suppose that I have three classes P, C1, C2, composition (strong aggregation) relations between P <>- C1 and P <>- C2, i.e. every instance of P contains an instance of C1 and an instance of C2, which are destroyed when the parent P instance is destroyed. an association relation between instances of C1 and C2 (not necessarily between children of the same P). To implement this, in C++ I normally define three classes P, C1, C2, define two member variables of P of type boost::shared_ptr<C1>, boost::shared_ptr<C2>, and initialize them with newly created objects in P's constructor, implement the relation between C1 and C2 using a boost::weak_ptr<C2> member variable in C1 and a boost::weak_ptr<C1> member variable in C2 that can be set later via appropriate methods, when the relation is established. Now, I also would like to have a link from each C1 and C2 object to its P parent object. What is a good way to implement this? My current idea is to use a simple constant raw pointer (P * const) that is set from the constructor of P (which, in turn, calls the constructors of C1 and C2), i.e. something like: class C1 { public: C1(P * const p, ...) : paren(p) { ... } private: P * const parent; ... }; class P { public: P(...) : childC1(new C1(this, ...)) ... { ... } private: boost::shared_ptr<C1> childC1; ... }; Honestly I see no risk in using a private constant raw pointer in this way but I know that raw pointers are often frowned upon in C++ so I was wondering if there is an alternative solution.

• Impossible to enable bluetooth under Ubuntu

  - by PCh

  I just installed Ubuntu 12.04 (dual boot, kept Windows just in case) on my new Acer Aspire One 756-877. As soon as I installed it I also installed the Broadcom driver, since wifi wasn't working, and that solved it right away. But when I tried Bluetooth, I had a problem that I see is quite recurring: -The hardware is on (and working fine under Windows) -The icon shows up on the menu, giving me the options of turning Bluetooth on or off, and then just "Bluetooth preferences". -I can apparently turn it on that way, which only lights up the icon but makes no difference at all (and doesn't give any other options in the Bluetooth menu) -When I open "Bluetooth preferences" (whether Bluetooth is apparently on or off, it makes no difference), it says it's disabled and will not let me slide the button to enable it. I've rebooted, but nothing happens. -The material is Broadcom and the port (if it's relevant at all) is Port_#0001.Hub_#0003 I tried the following commands suggested in other similar questions, with no result at all: sudo dmesg | grep blue and sudo service bluetooth start and sudo /etc/init.d/bluetooth start Any other clues on what I can do? Thanks for your time!

• How to apply verification and validation on the following example

  - by user970696

  I have been following verification and validation questions here with my colleagues, yet we are unable to see the slight differences, probably caused by language barrier in technical English. An example: Requirement specification User wants to control the lights in 4 rooms by remote command sent from the UI for each room separately. Functional specification The UI will contain 4 checkboxes labelled according to rooms they control. When a checkbox is checked, the signal is sent to corresponding light. A green dot appears next to the checkbox When a checkbox is unchecked, the signal (turn off) is sent to corresponding light. A red dot appears next to the checkbox. Let me start with what I learned here: Verification, according to many great answers here, ensures that product reflects specified requirements - as functional spec is done by a producer based on requirements from customer, this one will be verified for completeness, correctness). Then design document will be checked against functional spec (it should design 4 checkboxes..), and the source code against design (is there a code for 4 checkboxes, functions to send the signals etc. - is it traceable to requirements). Okay, product is built and we need to test it, validate. Here comes our understanding trouble - validation should ensure the product meets requirements for its specific intended use which is basically business requirement (does it work? can I control the lights from the UI?) but testers will definitely work with the functional spec, making sure the checkboxes are there, working, labelled, etc. They are basically checking whether the requirements in functional spec were met in the final product, isn't that verification? (should not be, lets stick to ISO 12207 that only validation is the actual testing)

• Benefits of Server-side Coding

  There are numerous advantages to server scripting languages over client side languages in regards to creating web sites that are more compelling compared to a standard static site. Server side scripting are scripts that are executed on a web server during the compilation of data to return to a client. These scripts allow developers to modify the content that is being sent to the user prior to the return of the data to the user as well as store information about the user. In addition, server side scripts allow for a controllable environment in which they can be executed. This cannot be said for client side languages because the developer cannot control the users’ environment compared to a web server. Some users may turn off client scripts, some may be only allow limited access on the system and others may be able to gain full control of the environment.  I have been developing web applications for over 9 years, and I have used server side languages for most of the applications I have built.  Here is a list of common things I have developed with server side scripts. List of Common Generic Functionality Send Email FTP Files Security/ Access Control Encryption URL rewriting Data Access Data Creation I/O Access The one important feature server side languages will help me with on my website is Data Access because my component will be backed with a SQL server database. I believe that form validation is one instance where I might see server-side scripts and JavaScript used interchangeably because it does not matter how or where the data is validated as long as the data that gets inserted is valid. However, I would have to say that my personal experience would have to sway me in deciding what type of languages to use for form validation because they both have advantages and disadvantages based on the each situation.

• Upgrade went wrong, laptop essentially 'bricked'

  - by hexagonheat

  I have an old netbook I was trying to upgrade from 10.04 to 10.10. Ubuntu was in the process of upgrading when everything completely froze. I left it sit for an hour but it would not respond to anything. So I powered down the machine and it didn't have the necessary files to run Ubuntu. I went to the terminal and it told me to put in some command that I can not remember to 'rebuild' something. That takes me to now, when I turn on the laptop it comes up with a screen "GNU GRUB version 1.98+20100804-5ubuntu3.3" and has a bunch of options such as: 1. Ubuntu, with Linux 2.6.35-32-generic 2. Ubuntu, with Linux 2.6.35-32-generic (recover mode) etc. (there are like 15 of these with different numbers after 2.6.35 and the word 'generic'. It doesn't seem to matter what I pick, it will go to the "Ubuntu" loading screen with the colored dots but then every time it will freeze and I have to reboot to the same thing. I can't seem to get a terminal prompt anywhere either. Any ideas? I can't think of what to do :(

• Simple multi-seat

  - by Oli

  I've asked about multiseat before. The answer (for 10.04) involved doing it the proper way (eg through gdm, multiple server layouts). The problem was that gdm needs to be patched or reverted to 2.20 for multiseat. It's an ugly hack that, worse than anything, will hold up future updates. As a result, I didn't do anything. I still have a spare video card. I still have the monitor, keyboard and mouse all sitting waiting to jump into action. And I still want to be able to turn that into a simple desktop. My needs don't seem complicated. I have a second video card, a USB hub and anything connected to that USB hub that I want to be dedicated to another X server. I don't need a login screen (I'm happy hard-coding in a auto-login and I'd be happy with the user starting the X server if that's possible). This is so simple in my head that I only need two questions: How can I explicitly start an X server from the command line on an unused video adapter (by passing it whatever configuration I need to)? Can I have this new X session load a desktop environment on load? This seems like something you should be able to write in a little upstart script within 10 minutes. That would be perfect for me as then I'd have a nice start/stop control over the secondary desktop from the main desktop (that I want to leave unscathed!) I'm thinking something as simple as this for the payload: su -u other_user -c "startx -- localhost hardware-information" And use .xinitrc to load openbox or something...

• Really slow wireless internet on 12.04 with HP dv6 6070ca

  - by Joe

  I was recently running the previous version of Ubuntu through Wine, and everything was working great. I decided to upgrade to pangolin when I saw it came out. After upgrading the internet was very slow (the estimated time on the updates was something like 4 days). I thought maybe this had something to do with the Wine installation, so I decided to finally do an actual dual boot. I partitioned my drive all nice and neat, but I made the mistake of connecting to the internet for the installation, and clicking the option to install updates and restricted extras. This was in the morning, circa 6 am. Fast forward to the evening, the installation is frozen at around 75%. In frustration I gave the ol girl a hard shut-down, which effectively rendered my machine useless. I used the thumb drive to reinstall Ubuntu, this time without connecting to the internet. Installed nice and easy, no problems, but the internet is still ridiculously slow. It took me about 20 minutes of frustration and hitting stop and reload repeatedly to even get this question page to open. This is important to me as now Windows won't even boot and I have to use ubuntu for the time being but I can't even bear to turn on my laptop due to the frustration that immediately ensues. Please help! Oh, and I'm relatively new so if there are some terminal commands that spew out info you guys would find useful let me know what they are and I'll post back the information.

• Old Lock Retrofitted for Wireless and Key-free Entry

  - by Jason Fitzpatrick

  What do you do if the old key your landlord gave you is poor fit for your apartment’s lock? If you’re the geeky sort, you build a wireless unlocking module to do the work for you. Instructables user Rybitski writes: The key to my apartment never worked quite right because it is a copy of a copy of a copy. I am fairly certain that the dead bolt is original to the building and the property manager seems to have lost the original key years ago. As a result unlocking the door was always a pain. Changing the lock wasn’t an option, but eliminating the need to use a key was. To that end, he built the device seen in the video above. An Arduino Uno drives a servo which in turn opens the deadbolt. The whole thing is controlled by a simple wireless key fob. Hit up the link below for the full build guide including code.

• Limiting the speed of the mouse cursor

  - by idlewire

  I am working on a simple game where you can drag objects around with the mouse cursor. As I drag the object around quickly, I notice there is some juddering, which seems to be due to the fact that I can move the mouse cursor faster than the game's update/draw. So, although I maintain the offset from where the player initially clicked on the object, the mouse's relative position to the object shifts around slightly before settling as I move the object very quickly. The only way I have found to get smooth, exact 1:1 movement is if I turn both IsFixedTimeStep and SynchronizeWithVerticalRetrace to false. However, I'd rather not have to do that. I have also tried making a custom mouse cursor, hiding the real mouse, taking the real mouse delta and clamping it to a maximum speed. Here is the problem: In windowed mode, the "real" mouse cursor moves off the window while the custom mouse cursor (since it's movement is being scaled) is still somewhere inside the game window. This becomes bizarre and is obviously not desired, as clicking at this point means clicking on things outside the game window. Is there any way to accomplish this in windowed mode? In fullscreen mode, the "real" mouse cursor is bounded to the edges of the screen. So I get to a point where there is no more mouse delta, yet my custom cursor is still somewhere in the middle of the screen and hence can't move further in that direction. If I wanted to clamp it to the edge of the screen when the real cursor is at the edge, then I would get an abrupt jump to the edge of the screen, which isn't desired either Any help would be appreciated. I'd like to be able to limit the speed of the mouse, but also would appreciate help with the first issue (the non-smooth relative offset between mouse cursor movement and object movement).

• Develop for Desktop and mobile use?

  - by ran2

  I am in the very beginning of developing an app / desktop program. I want it to be cross-platform and possibly also as a tablet version (preferably Android Icecream sandwich). Note that I need to run it offline. I thought about the following approaches: ADOBE Air, since I do not need much performance. Plus I did some web programming in the past which might be of some use. Afaik it would run on OS X and Windows and should run on mobile OSes, too. Qt. Found some nice Qt based desktop recently and read it also works on android. Plus I like the SDK. HTML5 / JS. Again my web background should help me here. I wont need no sever side scripts, thus it should work without installing anything but a browser. How easy could this be converted into an Android app? There might be a plethora of other (better) ways to do it, but I haven't thought of them yet. Can you help out? How would you create such an application. Would it be better to do some pure desktop client and then create tablet versions? Would you rather start to create a website and worry later on how to turn into an app?

• Lost WiFi after 12.10 upgrade

  - by Steven Guillory

  I received my new Dell Vostro 2420 last week, and just got around to upgrading from 11.10 to 12.10. Unfortunately, like many others (after researching the issue), I no longer have WiFi. I have tried every sudo command given that worked for others, and still can't get my wireless to function. I am new to Linux, so any and all help is appreciated. Thanks in advance!

• A Cost Effective Solution to Securing Retail Data

  - by MichaelM-Oracle

  By Mike Wion, Director, Security Solutions, Oracle Consulting Services As so many noticed last holiday season, data breaches, especially those at major retailers, are now a significant risk that requires advance preparation. The need to secure data at all access points is now driven by an expanding privacy and regulatory environment coupled with an increasingly dangerous world of hackers, insider threats, organized crime, and other groups intent on stealing valuable data. This newly released Oracle whitepaper entitled Cost Effective Security Compliance with Oracle Database 12c outlines a powerful story related to a defense in depth, multi-layered, security model that includes preventive, detective, and administrative controls for data security.

• Getting the PC speaker to beep

  - by broiyan

  There has been much written on getting the beep sound from Ubuntu releases over the years. Example: fixing the beep My needs are slightly different in that I do not want to ensure sound card beeps are functioning. Instead, I want PC speaker beeps, the kind produced by the original built-in speaker because I believe they will produce less CPU load. I have confirmed that my computer has the PC speaker by unplugging the external speakers and shutting down Ubuntu. At some point in the shutdown and restart process a beep is heard even though the external speakers have no power. I have tried the following: In /etc/modprobe.d/blacklist.conf, turn these lines into comments: #blacklist snd_pcsp #blacklist pcspkr In .bashrc /usr/bin/xset b on /usr/bin/xset b 100 Enable in the gnome terminal: Edit Profile Prefs General Terminal Bell Ensure no "mute" selections in: System Prefs Sound various tabs (uncheck them all). Select "Enable window and button sounds" in: System Prefs Sound Sound Effects In gconf-editor desktop gnome sound, select the three sound check boxes. In gconf-editor apps metacity general select the audible bell check box. Still I get no PC speaker beeps when I send code 7 to the console via my Java program or use echo -e '\a' on the bash command line. What else should I try? Update Since my goal is to minimize load on the CPU, here is a comparison of elapsed times. Each test is for 100,000 iterations. Each variant was performed three times so three results are presented for each. printwriter.format("%c", 7); // 1.3 seconds, 1.5 seconds, 1.5 seconds Toolkit.getDefaultToolkit().beep(); // 0.8 seconds, 0.3 seconds, 0.5 seconds try { Runtime.getRuntime().exec("beep"); } catch (IOException e) { } // 10.3 seconds, 16.3 seconds, 11.4 seconds These runs were done inside Eclipse so multiply by some value less than 1 for standalone execution. Unfortunately, Toolkit's beep is silent on my computer and so is code 7. The beep utility works but has the most cost.

• Putting DSMD into Remission

  - by Justin Greenwood

  As a programmer with over ten years of professional experience, I've often suffered from DSMD (distraction surplus/motivation deficit) disorder. I know I'm not alone. Many of my colleagues have shared their experiences with this productivity cancer to me in support groups or in moments of inebriated intimacy. Often, I observe friends unknowingly surrendering to it - sitting at their computer, cycling through the same set of web sites (blogs, facebook, youtube, news providers, wikipeida, etc.), over and over again. Intermittently, they get up, take a walk around the office, make small talk with their colleagues, get another cup of coffee, then sit down and start the cycle all over again. It is completely controlled by the subconscious mind and will destroy your ability to get into that groove you used to live in back in your better days. Programming requires extended periods of focused attention, and this type of behavior will really kill productivity and in the end, when deadlines are near, launch your stress level to near emotional breakdown levels.DiagnosisThe best way to diagnose infection is to completely disconnect your devices from the internet while working. If you find yourself launching web browsers every minute or so, then you're down with the sickness.TreatmentA few techniques I've found that will help send this ailment into regression are as follows:Segment your day into two to three hour work segments. For example: 9:00-11:00, 1:00-3:00, 3:30-5:00.Define a few small one to two hour tasks you want to accomplish in your day. Assign each of those tasks to one of the short work segments.If possible, turn off the internet and any other distractions during these work segments (at least until you regain control of your browsing habits) - this includes instant messaging and email. You can check your email and waste time surfing in the hours between work segments.Reward yourself on productive days with a beer or whatever butters your muffins.

• whats the name of this pattern?

  - by Wes

  I see this a lot in frameworks. You have a master class which other classes register with. The master class then decides which of the registered classes to delegate the request to. An example based passed in class may be something this. public interface Processor { public boolean canHandle(Object objectToHandle); public void handle(Object objectToHandle); } public class EvenNumberProcessor extends Processor { public boolean canHandle(Object objectToHandle) { if (!isNumeric(objectToHandle)){ return false } return isEven(objectToHandle); } public void handle(objectToHandle) { //Optionally call canHandleAgain to ensure the calling class is fufilling its contract doSomething(); } } public class OddNumberProcessor extends Processor { public boolean canHandle(Object objectToHandle) { if (!isNumeric(objectToHandle)){ return false } return isOdd(objectToHandle); } public void handle(objectToHandle) { //Optionally call canHandleAgain to ensure the calling class is fufilling its contract doSomething(); } } //Can optionally implement processor interface public class processorDelegator { private List processors; public void addProcessor(Processor processor) { processors.add(processor); } public void process(Object objectToProcess) { //Lookup relevant processor either by keeping a list of what they can process //Or query each one to see if it can process the object. chosenProcessor=chooseProcessor(objectToProcess); chosenProcessor.handle(objectToProcess); } } Note there are a few variations I see on this. In one variation the sub classes provide a list of things they can process which the ProcessorDelegator understands. The other variation which is listed above in fake code is where each is queried in turn. This is similar to chain of command but I don't think its the same as chain of command means that the processor needs to pass to other processors. The other variation is where the ProcessorDelegator itself implements the interface which means you can get trees of ProcessorDelegators which specialise further. In the above example you could have a numeric processor delegator which delegates to an even/odd processor and a string processordelegator which delegates to different strings. My question is does this pattern have a name.
