• Ubuntu Karmic, Maximize delay problem

  - by Loukas990

  Hello, I have tried various ubuntu versions, Ubuntu Karmic Koala 9.10 x86, Ubuntu 10.04 beta DVD, Ubuntu 9.10 AMD64, Mandriva 2010 x86, also a Fedora version and after installing compiz on all OS's, everything is working normal and smooth, even the compiz effects, cube, water, fire, wobbling windows, etc, except of the Maximize effect, where i get 2seconds+ delay for the effect. Cause it got me in a lot of thinking, why im getting this delay "problem", do you think there is any solution? or at least a way to decrease the delay? Thanks in advance. ;) P.S. My laptop is a Toshiba Satellite P300d, AMD Turion 64 x2 Dual-Core TL-64 (2.20 GHz), ATI Mobility Radeon™ HD 3650 512MB, 3GB RAM.

• How lookaheads are propagated in "channel" method of building LALR parser?

  - by greenoldman

  The method is described in Dragon Book, however I read about it in ""Parsing Techniques" by D.Grune and C.J.H.Jacobs". I start from my understanding of building channels for NFA: channels are built once, they are like water channels with current you "drop" lookahead symbols in right places (sources) of the channel, and they propagate with "current" when symbol propagates, there are no barriers (the only sufficient things for propagation are presence of channel and direction/current); i.e. lookahead cannot just die out of the blue Is that right? If I am correct, then eof lookahead should be present in all states, because the source of it is the start production, and all other production states are reachable from start state. How the DFA is made out of this NFA is not perfectly clear for me -- the authors of the mentioned book write about preserving channels, but I see no purpose, if you propagated lookaheads. If the channels have to be preserved, are they cut off from the source if the DFA state does not include source NFA state? I assume no -- the channels still runs between DFA states, not only within given DFA state. In the effect eof should still be present in all items in all states. But when you take a look at DFA presented in book (pdf is from errata): DFA for LALR (fig. 9.34 in the book, p.301) you will see there are items without eof in lookahead. The grammar for this DFA is: S -> E E -> E - T E -> T T -> ( E ) T -> n So how it was computed, when eof was dropped, and on what condition? Update It is textual pdf, so two interesting states (in DFA; # is eof): State 1: S--- >•E[#] E--- >•E-T[#-] E--- >•T[#-] T--- >•n[#-] T--- >•(E)[#-] State 6: T--- >(•E)[#-)] E--- >•E-T[-)] E--- >•T[-)] T--- >•n[-)] T--- >•(E)[-)] Arc from 1 to 6 is labeled (.

• YouTube: Promotional AgroSense Movie

  - by Geertjan

  Here's a cool YouTube promotional movie on AgroSense created by Ordina in the Netherlands. AgroSense is an open source Java system for the precision agriculture industry, which won the IT Environment Award in the Netherlands last week: If your understanding of Dutch limits your appreciation of the movie above, here's a rough translation, together with the names of the speakers in the movie: Precision agriculture, an innovative form of agriculture in which local variations in soil, crop, and atmosphere are taken into account, is the high-tech sustainable agriculture of tomorrow. The use of fertilizer, water, and energy can in this way be significantly reduced. "If, ten or twenty years from now, we are to continue having our agricultural industry in good shape, and in a continuing state of health, we'll need to register and work with data because if we want to enable crops to provide higher value, we'll need to create higher levels of transparency throughout the agriculture chain." Lenus Hamster, farmer in Nieuwolda Groningen "Industry is becoming increasingly data intensive. By combining pragmatic usefulness with innovative sustainability, AgroSense offers the Netherlands the possibility to continue being a leading player in the agrofood sector." Art Lighthart, Architect at Ordina AgroSense offers an open source solution in which all services for precision agriculture are brought together. In 2012, co-operation is being sought with organizations to make AgroSense available to around 10,000 Dutch farmers in the arable crop sector. By the way, the last sentence above implies the NetBeans Platform will be used by around 10,000 Dutch farmers.

• Random World Generation

  - by Alex Larsen

  I'm making a game like minecraft (although a different idea) but I need a random world generator for a 1024 block wide and 256 block tall map. Basically so far I have a multidimensional array for each layer of blocks (a total of 262,114 blocks). This is the code I have now: Block[,] BlocksInMap = new Block[1024, 256]; public bool IsWorldGenerated = false; Random r = new Random(); private void RunThread() { for (int BH = 0; BH <= 256; BH++) { for (int BW = 0; BW <= 1024; BW++) { Block b = new Block(); if (BH >= 192) { } BlocksInMap[BW, BH] = b; } } IsWorldGenerated = true; } public void GenWorld() { new Thread(new ThreadStart(RunThread)).Start(); } I want to make tunnels and water but the way blocks are set is like this: Block MyBlock = new Block(); MyBlock.BlockType = Block.BlockTypes.Air; How would I manage to connect blocks so the land is not a bunch of floating dirt and stone?

• Penne alla MVP

  - by Valter Minute

  I’m sorry for the long silence on this blog and the long delay in replying to the friends that commented on my articles. I’ve been quite busy in the last weeks and I spent a lot of time traveling around Italy (not for pleasure!). In the meantime I’ve been renewed as an MVP on April the 1st (nice date to renew someone with such a bad sense of humor…). I decided to celebrate my MVP award with a new recipe (to be honest, I celebrated by eating the results of this recipe!) and I decided to call it “penne alla MVP”… just because I’m not good in finding nice names for my recipes. Ingredients (for 4 people): 360g pasta (penne or other short pasta) 300g small shrimps 1 cup of whipped cream 2 tablespoons of olive oil 1 small leek 1 glass of beer (I used Hoegaarden dutch white beer… but just because I like it and I finished the rest of the bootle while cooking) Chives Salt, pepper Prepare the pasta by boiling it in salted water, as usual. In the meantime chop the leek in very small bits, heat the oil inside a pan and when the oil is hot, drop the leek chops and let them cook for a few minutes. Add the shrimps and the glass of beer. Let them cook inside beer until they are cooked (if you used pre-cooked shrimps a couple of minutes would be enough to heat them and gave them the flavour of beer). Add the whipped cream and mix it well with the shrimps and the sauce. Dry the pasta and drop the sauce on top of it and then add the chives finely chopped.

• Should I have seperate business and personal websites?

  - by Thomas Clowes

  I have my business website - I am a web designer and developer, and also buy/sell websites/domain names. As such my website links to 'Our sites' = the websites which we design and run as well as a variety of tools such as a domain whois tool. These are obviously relevant to the business. As an individual, I like to travel and do white water kayaking as a hobby. I also have a degree in economics. I have thus created a blog on my business website where I write about domain names, web design, kayaking, travelling and economics. I've just begun researching SEO and am looking into optimizing my business website. I don't actually directly offer any services to clients at the moment, my main aim is to have a business website which supports my websites. If for example a potential advertise on one of my sites checks out the business website, I want them to think professional, down to earth, quirky. Given this is having my business/personal interests intertwined a problem? For SEO.. on my homepage for example when I'm writing a headline and a paragraph about what we do.. what do I put? and how do I optimize for SEO with keywords and the like? Further to the above, my company sponsors me and a group of accquantances as a kayaking team.. as such my personal interests do sort of overlap (just to add a complexity :))

• JavaOne User Group Sunday

  - by Tori Wieldt

  Before any "official" sessions of JavaOne 2012, the Java community was already sizzling. User Group Sunday was a great success, with several sessions offered by Java community members for anyone wanting to attend. Sessions were both about Java and best practices for running a JUG. Technical sessions included "Autoscaling Web Java Applications: Handle Peak Traffic with Zero Downtime and Minimized Cost,"  "Using Java with HTML5 and CSS3," and "Gooey and Sticky Bits: Everything You Ever Wanted to Know About Java." Several sessions were about how to start and run a JUG, like "Getting Speakers, Finding Sponsors, Planning Events: A Day in the Life of a JUG" and "JCP and OpenJDK: Using the JUGs’ “Adopt” Programs in Your Group." Badr ElHouari and Faiçal Boutaounte presented the session "Why Communities Are Important and How to Start One." They used the example of the Morocco JUG, which they started. Before the JUG, there was no "Java community," they explained. They shared their best practices, including: have fun, enjoy what you are doing get a free venue to have regular meetings, a University is a good choice run a conference, it gives you visibility and brings in new members students are a great way to grow a JUG Badr was proud to mention JMaghreb, a first-time conference that the Morocco JUG is hosting in November. They have secured sponsors and international speakers, and are able to offer a free conference for Java developers in North Africa. The session also included a free-flowing discussion about recruiters (OK to come to meetings, but not to dominate them), giving out email addresses (NEVER do without permission), no-show rates (50% for free events) and the importance of good content (good speakers really help!). Trisha Gee, member of the London Java Community (LJC) was one of the presenters for the session "Benefits of Open Source." She explained how open sourcing the LMAX Disruptor (a high performance inter-thread messaging library) gave her company LMAX several benefits, including more users, more really good quality new hires, and more access to 3rd party companies. Being open source raised the visibility of the company and the product, which was good in many ways. "We hired six really good coders in three months," Gee said. They also got community contributors for their code and more cred with technologists. "We had been unsuccessful at getting access to executives from other companies in the high-performance space. But once we were open source, the techies at the company had heard of us, knew our code was good, and that opened lots of doors for us." So, instead of "giving away the secret sauce," by going open source, LMAX gained many benefits. "It was a great day," said Bruno Souza, AKA The Brazilian Java Man, "the sessions were well attended and there was lots of good interaction." Sizzle and steak!

• Java Applet or Unity3D for Cross-Platform 3D Surveying App

  - by Jake M

  Do you think a Java Applet or Unity3D Application is the best option to make a cross-browser 3d web-app? I intend to make a web application that displays 3d environments that can be navigated by dragging(with a finger or mouse depending on the platform). The web app will render 3d environments of development sites including contours, water pipeline locations, buildings etc. The application must work on Windows Desktop, Android, iOS and Windows Phone. So this is why I am tending towards a web-app as opposed to cross-platform smart phone library(like Mosync or Marmalade). The 3d environments will be navigable(by dragging around) and contain simple(not detailed) 3d objects like buildings, mountains, pipelines, etc. One thing I know is that WebGL is out because it doesn't work on IE and has limited support on Smart Phones(am I correct to completely disregard WebGL?). Will future Smart Phone browsers continue to support Java Applets? Also is it really true I can write ONE Application/Game in Unity3D and simply compile it to run on Windows Windows, Mac, Xbox 360, PlayStation 3, Wii, iPad, iPhone and Android? Would you suggest the Unity3D application path or the Unity3D Web Player path? Concerning Unity3D, there's one thing I am unsure about: do all Unity3D features work on iOS and Android?

• Ten Classic Electronic Toys and Their Modern Equivalents

  - by Jason Fitzpatrick

  Whether you’re looking to relive the toy exploits of your youth or pass your love of tinkering and electronics onto the younger generation, this list highlights ten great electronic toys of yesteryear and their modern equivalents. Courtesy of Wired’s Geek Dad, the description for the all-in-one electronics kit seen here: What is was: Arthur C. Clarke has said that any sufficiently advanced technology is indistinguishable from magic. As a kid in the midst of an increasing technological revolution, electronics were at the heart of that. Learning electronics was made easy through the Science Fair Electronic Project Kits found at Radioshack. Through the project guides, kids could construct various ‘experiments’ by attaching wires to terminal springs that make circuits. The terminal springs would wire in components such as LED segment lights, photo sensors, resistors, diodes, etc. While it was fun getting the projects to work, the manuals lacked in depth explanation as to what was happening in the circuit to produce the project’s result. Why it was awesome: First, it was a simple buy for parents. Everything you needed to get your child interested in electronics was right in the kit. You didn’t need to breadboard or solder. I remember a distinct feeling of accomplishment making a high-water alarm or a light-sensor game with the realization that the bundles of wires springing up from the kit were actually doing something! Modern equivalent: You can still pick up variations of the 100-in-1 kits, but their popular replacement seem to be Snap Circuits by Elenco. All of the components are mounted on a plastic base with a contact on either end which interconnect with each other and the plastic base that projects can be mounted to. Each component also has the electrical diagram symbol for that component drawn on it so it can help you read schematics. For that reason alone, I like these better.

• Need alternative to Accessibility's "Locate Pointer" to visually highlight the mouse.

  - by fred.bear

  Update: See end of quetion: A black-on-white cross-hair/I-bar mouse-pointer is soemtimes hard foe me to spot in amongst black-on-white text. I've tried "Accessibility / Mouse Accessibility / Locate Pointer" .. which will: Show pointer position when Control is presssed It works (to a point), but it does have a notable problem, which renders it inpractical. It has the uncanny side-effect of disallowing all Control key navigation while editing a file/dir name in Nautilus (F2).. Just touching the Control key drops it out of edit mode, which means I can't keyboard paste, move-L/R word etc... So, I'm looking for an alternative. I've tried Compiz's Water Effect, but I need something which is sharper, faster, and localized to the pointer. Compiz's Show Mouse (with fire) is no suitable. I'm really lookingf for an analog of "Accessibility / Locate Pointer": * ie. I hit Control (only).. and it blips a quick visual pulse. UPDATE: I've just realized why I can't find my mouse so often! ... It's because it is isn't there !!! ... Two apps I use a lot, Gedit and Konsole (KDE Terminal; it renders unicode better), ... dissolve the mouse-pointer to invisible after the first key is typed ... and Konsole does it after a few seconds of idle-time... like a video-player option: "hide the mouse".. Well I don't use the mouse much, and I thought it was juse my eyesight (which does rely a lot on Compiz's zoom)... I discovered it when I installed a "novelty" app, called Geyes from gnome-applets ("A goofy set of eyes for the GNOME panel. They follow your mouse.") ... It could follow the mouse better than me! :)

• Get to Know a Candidate (6 of 25): Jill Stein&ndash;Green Party

  - by Brian Lanham

  DISCLAIMER: This is not a post about “Romney” or “Obama”. This is not a post for whom I am voting. Information sourced for Wikipedia. Stein is a physician with degrees from Harvard College and Harvard Medical School.  She serves on the boards of Greater Boston Physicians for Social Responsibility and MassVoters for Fair Elections, and has been active with the Massachusetts Coalition for Healthy Communities Jill Stein advocates a "Green New Deal" in which renewable energy jobs would be created to address climate change and environmental issues with the objective of employing "every American willing and able to work". Citing the research of Dr. Phillip Harvey, Professor of Law & Economics at Rutgers University, as evidence of the successful economic effects of the 1930s' New Deal projects, Stein would fund the plan with a 30% reduction in the U.S. military budget, returning US troops home, and increasing taxes on areas such as capital gains, offshore tax havens and multimillion dollar real estate. Stein plans on impacting what she sees as a growing convergence of environmental crises in water, soil, fisheries and forests, through the creation of sustainable infrastructure based in clean renewable energy generation and sustainable communities principles such as increasing intra-city mass transit and inter-city railroads, creating 'complete streets' that safely encourage bike and pedestrian traffic and regional food systems based on sustainable organic agriculture The Green Party of the United States was founded in 1991 as a voluntary association of state green parties. With its founding, the Green Party of the United States became the primary national Green organization in the United States, eclipsing the Greens/Green Party USA, which emphasized non-electoral movement building. The Green Party of the United States of America emphasizes environmentalism, non-hierarchical participatory democracy, social justice, respect for diversity, peace and nonviolence. Their "Ten Key Values," which are described as non-authoritative guiding principles, are as follows: Grassroots democracy Social justice and equal opportunity Ecological wisdom Nonviolence Decentralization Community-based economics Feminism and gender equality Respect for diversity Personal and global responsibility Future focus and sustainability The Green Party does not accept donations from corporations. Thus, the party's platforms and rhetoric critique any corporate influence and control over government, media, and American society at large. Stein has access to 403 electoral votes and is a write-in candidate in GA, IN, and MS Learn more about Jill Stein and Green Party on Wikipedia.

• Fan always on and overheating problems on HP G62

  - by Dave

  I have a HP G62 with i5 processor, 4G Ram and ATI HD 5470. Started using Ubuntu 4 months ago, first was 11.10 and after 12.04. Everything worked perfectly until some weeks ago when my cpu fan became "crazy" and I mean by this always on, noise and overheating problems, for sure if I put a glass with water in some minutes will boil (and I mean it). There can be a bug in the last kernel or any other Ubuntu's official update? And by the way CPU fan is cleaned like a new born baby; Used jupiter and all those stuff (lm-sensor, psensor...) - same problem; Don't ask me to install ATI drivers because will work like sh#t (interface laggy as HD 5470 isn't supported by Ubuntu) and I can't even open ATI Catalyst (error when I try to open it), more than this I always used open source drivers and as I said, worked perfectly (3d, effects). Right now I'm back to Windows and everything is working perfectly but my main problem is that I get used with Ubuntu and kinda weird to use windows again. I want back my nice and almost perfect Ubuntu. Thanks, Dave

• Applying Textures to Hexagonal Tiles Seamlessly

  - by PATRY

  I'm doing a tactical game (X-Com / Fallout style) for fun. I've decided to use a hexagonal map, but I'm having a graphic problem. My current map display is HUD-like, with only the border of the map cells displayed, without any texture. it's simple and allow for display of different types of informations by varying the color of the border. For exemple the "danger view mode" displays the borders with a color going from green (no damage possible) to red (prob of damage 90%). Now, It's a bit hard to differentiate the kind of tile the player is on. I could put a plain color (green is grass, pale blue is water...), but this is going to limit the possibilities. Thus, i would like to display a texture on my tiles. Since the map are generated, i can not use a picture for the whole map with the HUD over. So, my question is : does any one knows how i could generate the sealess hexagonal textures (algo or plugin), or if there is a site with some hexagonal tiles ?

• Developing configuration syntax - best practise/rules/methods?

  - by Isaac

  I am currently developing a small application, which checks if provided data meets certain requirements. The requirements are actually a long list, and might be changing, so I defined a syntax which allows me to state all of the requirements briefly and in a seperate file. Now the overall requirements for the application have changed, and I need to change my configuration syntax. Which leeds me to wonder if there is methodoloy or best practise for developing such syntaxes. Currently what I do is I think about the requirements and come up with an initial syntax, start configuring the first few items and see how it works. If I come upon something that does not work well or not at all with the current syntax, I change the syntax, if possible in a backward compatible way. This somehow works for me, but it feels a bit like fishing in troubled water. Also I feel it does not nessessarly lead to the most concise and easy to understand/use syntax. So I was wondering what other people do, especially if there is a better approach to this.

• Reaching Intermediate Programming Status

  - by George Stocker

  I am a software engineer that's had positions programming in VBA (though I dare not consider that 'real' experience, as it was trial and error!), Perl w/ CGI, C#, and ASP.NET. The latter two are post-undergraduate, with my entrance into the 'real world'. I'm 2 years out of college, and have had 5 years of experience (total) across the languages I've mentioned. However, when it comes to my resume, I can only put 2 years down for C#, and less than a year down for ASP.NET. I feel like I know C#, but I still have to spend time going 'What does this method do?', whereas some of the more senior level engineers can immediately say, "Oh, Method X does this, without ever having looked at that method before." So I know empirically that there's a gulf there, but I'm not exactly sure how to bridge it. I've started programming in Project Euler, and I picked up a book on design patterns, but I still feel like I spend each day treading water, instead of moving forward. That isn't to say that I don't feel like I've made progress, it just means that as far as I come each day, I still see the mountain top way off in the distance. My question is this: How did you overcome this plateau? How long did it take you? What methods can you suggest to assist me in this? I've read through Code Complete, The Mythical Man Month, and CLR via C#, 2nd edition -- my question is: What do I do now? Edit: I just found this question on projects for an intermediate level programmer. I think it adds to the discussion (though it does not supplant my question). As such, I'm adding it to the question as a "For More Information".

Oracle fully supports "Devoxx UK" and "Devoxx France" as a European Platinum Partner. Submit proposals and participate in both conferences since they are a two-hour train ride away from one another. The Devoxx conferences are designed “for developers by developers.” The conference committees are looking for speakers who are passionate developers unafraid to share their knowledge of Java, mobile, web and beyond. The sessions are about frameworks, tools and development with in-depth conference sessions, short practical quickies, and bird-of-a-feather discussions. Those different formats allow speakers to choose the best way to present their topics and can be mentioned during the submission process Devoxx has proven its success under Stephan Janssen, organizer of Devoxx in Belgium for the past 11 years. Devoxx has been the biggest Java conference in Europe for many years. To organize those local conferences, Stephan has enrolled the top community leaders in the UK and France. Ben Evans and Martijn Verberg are the leaders of London Java User Group (JUG) and are also known internationally for starting the Adopt-a-JSR program. Antonio Goncalves is the leader of the Paris JUG. He organized last year’s Devoxx France, which was a big success with twice the size first expected. The organizers made sure to add the local character to the conferences. "The community energy has to feel right," said Ben Evans and for that he picked an "old Victoria hall" for the venue. Those leaders are part of very dynamic Java communities in France and in the UK. France has 22 JUGs; the Paris JUG alone has 2,000 members. The UK has over 50,000 developers working in London and its surroundings; a lot of them are Java developers working in the financial industry. The conference fee is kept as low as possible to encourage those developers to attend. Devoxx promises to be crowded and sold out in advance. Make sure to submit your talks to both Devoxx UK and France before January 31st, 2013.

• 12.04 update crash, now cannot boot

  - by EdW

  Boot now freezes the system at the "Ubuntu purple screen" with the 5 dots under it. I cannot even CTRL-ALT-F1 to get to an alternate console. Have to push reset button on computer to reboot. After the 12.04 update crash, the system would boot, but I had no icons and no launch bar and errors about missing dependencies. CTRL-ALT-F1 and ran apt-get -f install and it appeared to get the missing packages. I followed with a apt-get update; apt-get upgrade. It appeared to install all of the remaining 12.04 update packages. Rebooted to same blank screen - no icons, but got a compiz error. In console I tried "unity --reset" rebooted ... Nothing ... It's dead in the water. Tried to boot into Recovery Mode - black screen - I cannot even CTRL-ALT-Del - have to push reboot button. Fortunately, I have Mint on another partition and I can access the broken 12.04 partition. Ideas? I can back up all of my folders using Mint, but I would hate to have to do a new install.

• Cocos2d v2.0 and OpenGL 2.0/1.0: where to start

  - by mm24

  I started developing my very first game 3 months ago using Cocos2d 2.0 for iPhone. I am now in the stage where I'd like to add some cool effects to the bullets and some special weapons (see my waveforms question here). I got a good answer in the cocos2d-iphone forum (see this one). Unfortunately I am a bit paralized now. I don't know if I will be overdoing by learning OpengGL 2.0 or if I should just stick ot the old 1.0. There is a good intro on various tutorial's written in Steffen Itterheims blog (see this post). I would like to add to my game: a blur effect to the bullets (here is a tutorial for OpenGL 1.0) a waveform (see above) some realistic water ripples (here is a nice sample code) So now, given that I don't want to overdo things but at the same time I want to achieve those effects, from where should I start? Should I discard the OpenGL 1.0 tutorials? OR should I use only OpenGL 1.0 code? How can I avoid confusion? I mean, it seems that the compiler recognizes both, but that there are some conflictual calls in some circumnstances, I am fairly sure this has some explanation, is there some reference to this somewhere?

• Scalable WordPress Host for High-Volume Site?

  - by Jonathan Eunice

  I need recommendations for a scalable web host for a high volume WordPress web site. For my purposes, high-volume might be 100K-500K visitors/hour. Might think towards a 1M/hour burst rate as a "high water mark." I know WP isn't the highest-performing platform out there (ha!), but it's non-negotiable. I can do "the usual optimizations" (e.g. put static files in a CDN, run and follow the advice of performance analyzers like YSlow, etc). But it will still be WordPress, and there will be a dozen or so plugins involved. So, where to host the site? Most "what's the best WordPress host?" discussions seem to focus on lowest-cost. I need the opposite. What are the high-volume, scalable, or clustered WordPress hosts with which you've had great experiences?
