  • Trouble WIth Immediate Shutdown in Ubuntu 13.10 with Cinnamon

    - by Sneha429
    Just installed Ubuntu on my family's computer. I thought the Cinnamon desktop environment would be better for my parents who have only ever used Windows. Everything works great until I try to shut down. Shutting down while in Cinnamon desktop brings up a prompt window that says it will shutdown in 60 seconds and gives the option to either suspend or cancel. The suspend button does not suspend the computer. Allowing the timer to countdown merely logs the current user out. Under power management, I have selected Shutdown Immediately for Power button action. I still get the same prompt. I have tried toggling between the other options, but regardless of what option is selected, the shutdown button always brings up the suspend or cancel prompt with no way to shutdown immediately. I would prefer not to use the power button for this as it is partially concealed with the computer desk. The fastest way to shutdown is to log out (which says it will log out in 60 seconds but also has log out and cancel buttons, so I can immediately log out) and then shutdown. I would prefer to have it automatically shut down. Any and all suggestions are appreciated. Thank you!

  • The year ahead, 2011.

    - by andrewstopford
    When I look back at last years look at 2010 my blogging rate has not changed much (I suspect this is largely down to using Twitter a lot) but my interests this year have developed a lot further. My view on 2010 would be that Microsoft would commit more to OSS, while I wanted to see more hires from that audience and more projects on Outercurve foundation instead there has been support for JQuery and Gems (aka NuGet). I would love to see more from Microsoft on the OSS front in 2011, Outercurve could become like the Apache foundation with enough support. Staying on the Microsoft front I predict that 2011 will bring the following. C# 5.0 will go RTM (still no MOP though) The next release of VS will go alpha or early beta MS MVC 4.0 (I think by Mix time) and maybe this release will get a command line. I also suspect that Microsoft will want to target the tablet market with WP7 in 2011 (Mix 2011 maybe...). I also predict the following Java will fork with Apache\Google. Oracle will then take them to court and the whole thing will boil right through 2011 (Java have had enough court cases, come on guys). Java and the JVM will sadly not move forward at all in 2011. Android will cause Apple a serious headache, both the smartphone and tablet market will see figures cut from Apple share. By the end of 2011 the current 70% apple market share will be 40-50%. As the features, performance and price of Android devices gets ever better Apple will be left out in the open. Lastly after 7 years I intend to move this blog away from weblogs. In 2011 I will be exploring Java, Ruby\Rails and Android and such subjects don't make sense to talk about it here. See you in 2011.

  • Is there an open source clone of a game in the Total War Series?

    - by sinekonata
    I loved Shogun:Total War gameplay and then later on spent weeks re-enacting historical wars and battles with Europa Barbarorum. It's a mod for Rome:TW that focuses on historical accuracy in the peoples, units, sounds, visuals, everything from macro mechanics to actual battles (e.g. a lot more missiles). Since that time I kind of turned my back on Windows cause it sucks and use Linux cause Mac sucks even worse. So as I miss that game (Eur. Barb.) and consider it the most realistic RTS to date, I'd like to know if there are any free and open source alternatives to it because ever since I'm under linux, I became addicted to FOSS so I also turned my back on paying (even kickstarters) for closed source, pay to play games. I have found a clone/alternative for everyone of the best games like Minecraft, CSS, Natural Selection, TA/SupCom etc... It's kind of the last one I need. The Spring engine is amazing for example, is there another open source project of the source in current development? Or would Spring itself be enough (it certainly looks capable) to make it? Thanks in advance guys...

  • Incorporating libs into module pattern

    - by webnesto
    I have recently started using require.js (along with Backbone.js, jQuery, and a handful of other JavaScript libs) and I love the module pattern (here's a nice synopsis if you're unfamiliar: http://www.adequatelygood.com/2010/3/JavaScript-Module-Pattern-In-Depth). Something I'm running up against is best practices on incorporating libs that don't (out of the box) support the module pattern. For example, jQuery without modification is going to load into a global jQuery variable and that's that. Require.js recognizes this and provides an example project for download with a (slightly) modified version of jQuery to incorporate with a require.js project. This goes against everything I've ever learned about using external libs - never modify the source. I can list a ton of reasons. Regardless, this is not an approach I'm comfortable with. I have been using a mixed approach - wherein I build/load the "traditional" JS libraries in a "traditional" way (available in the global namespace) and then using the module pattern for all of my application code. This seems okay to me, but it bugs me because one of the real beauties of the module pattern (no globals) is getting perverted. Anyone else got a better solution to this problem?

  • Who is a CMS really for?

    - by Eirc man
    I have started lately discovering Content Management Systems, and I was wondering, who is really CMS for? What I mean by that: is it only for companies, small businesses or individuals, that pays a contractor to make a website that it's users can just upload content through a easy interface. Or is it used also by programmers, to build their own websites, projects? Would a Facebook, Tweeter, StackExhange ever started by using a CMS, a very powerful one for example. Would you as a programmer build your own "fancy" website on top of a CMS, for example like Typo3, or you would build it from scratch? P.S To be more clear is a summary: What I mean to begin with is, would I as a developer choose a CMS to develop a website that can be scaled with a big base of users, be stuck if I choose to start with a CMS system. What if I build a website using CMS, and the website explodes in popularity, and then I wanted to add much more functionality that I have planed, is it possible that the CMS will limit the growth, because it might have not been build for that kind of scale?

  • Using runtime generic type reflection to build a smarter DAO

    - by kerry
    Have you ever wished you could get the runtime type of your generic class? I wonder why they didn’t put this in the language. It is possible, however, with reflection: Consider a data access object (DAO) (note: I had to use brackets b/c the arrows were messing with wordpress): public interface Identifiable { public Long getId(); } public interface Dao { public T findById(Long id); public void save(T obj); public void delete(T obj); } Using reflection, we can create a DAO implementation base class, HibernateDao, that will work for any object: import java.lang.reflect.Field; import java.lang.reflect.ParameterizedType; public class HibernateDao implements Dao { private final Class clazz; public HibernateDao(Session session) { // the magic ParameterizedType parameterizedType = (ParameterizedType) clazz.getGenericSuperclass(); return (Class) parameterizedType.getActualTypeArguments()[0]; } public T findById(Long id) { return session.get(clazz, id); } public void save(T obj) { session.saveOrUpdate(obj); } public void delete(T obj) { session.delete(obj); } } Then, all we have to do is extend from the class: public class BookDaoHibernateImpl extends HibernateDao { }

  • Prevent Click Fraud in Advertisement system with PHP and Javascript

    - by CodeDevelopr
    I would like to build an Advertising project with PHP, MySQL, and Javascript. I am talking about something like... Google Adsense BuySellAds.com Any other advertising platform My question is mainly, what do I need to look out for to prevent people cheating the system and any other issues I may encounter? My design concept. An Advertisement is a record in the Database, when a page is loaded, using Javascript, it calls my server which in turn will use a PHP script to query the Database and get a random Advertisement. (It may do kore like get an ad based on demographics or other criteria as well) The PHP script will then return the Advertisement to the server/website that is calling it and show it on the page as an Image that will have a special tracking link. I will need to... Count all impressions (when the Advertisement is shown on the page) Count all clicks on the Advertisement link Count all Unique clicks on the Advertisement link My question is purely on the query and displaying of the Advertisement and nothing to do with the administration side. If there is ever money involved with my Advertisement buying/selling of adspace, then the stats need to be accurate and make sure people can't easily cheat the system. Is tracking IP address really the only way to try to prevent click fraud? I am hoping someone with some experience can clarify I am on the right track? As well as give me any advice, tips, or anything else I should know about doing something like this?

  • One Step-Ahead A-Star

    - by Jonathan Dickinson
    I am attempting to create a server-centric RTS (as opposed to usual parallel synchronised simulation route of most RTS games today) - however I am still leveraging the discreet N-turns-ahead paradigm discussed by one of the AOE developers on Gamasutra. I have [possibly questionably?] decided that the path finding should only ever find the next cell the entity needs to move to, and was wondering if anyone has any clever ideas on how to optimize the algorithm for this specific scenario - or any other ideas on how to keep the pathfinding as lean as possible on the server. I have investigated a few possible algorithms but could only come up with one appropriation: Tiered A-Star - Relatively large T1 tiles, work out (and cache) each cell as you enter it. Other than that: doing the full A-Star pass and caching the entire path, which might use too much memory if a large amount of units are present. I know about the existence of naive progressive pathfinding algorithms (if you hit a block, turn in the direction closer to your target etc.) but they suffer from infinite feedback loops - and very poor pathing even if visited blocks are memorised. Not an option. Many thanks.

  • 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".

  • Regulation of the software industry

    - by Flexo
    Every few years someone proposes tighter regulation for the software industry. This IEEE article has been getting some attention lately on the subject. If software engineers who write programs for systems that expose the public to physical or financial risk knew they would be tested on their competence, the thinking goes, it would reduce the flaws and failures in code—and maybe save a few lives in the bargain. I'm skeptical about the value and merit of this. To my mind it looks like a land grab by those that proposed it. The quote that clinches that for me is: The exam will test for basic knowledge, not mastery of subject matter because the big failures (e.g. THERAC-25) seem to be complex, subtle issues that "basic knowledge" would never be sufficient to prevent. Ignoring any local issues (such as existing protections of the title Engineer in some jurisdictions): The aims are noble - avoid the quacks/charlatans1 and make that distinction more obvious to those that buy their software. Can tighter regulation of the software industry ever achieve it's original goal? 1 Exactly as regulation of the medical profession was intended to do.

  • recent unreliable wireless connection on 10.04 and 10.10

    - by gabkdlly
    Recently, my internet connection over wireless has become unreliable, on both a Dell laptop running Ubuntu 10.04 as well as my Desktop running Ubuntu 10.10 . The problem does not seem to occur on a laptop running Windows Vista. The problem does not seem to occur on my Openmoko Freerunner ( running Android 1.5 ), though I hardly ever use this device to connect over WLAN, so the problem may have just slipped by. This problem does not seem to appear when I boot into Ubuntu 9.10 from a live CD ( more precisely, I was able to ping fu-berlin.de for an hour without any packet loss ). Under Ubuntu 10.10, I am experiencing about 33% packet loss. On my main Ubuntu Desktop, I have tried the following wireless devices: a Longshine PCI card ( an old device with an RTL8180L chip ) a D-Link DWL-510 PCI card ( this device threw warnings in dmesg ) a USB device from MSI ( US54EX ). Usually my wireless network shows up in the network manager with a normal signal strength, even when the connection speed is slow ( which happens often ) or the connection gets reset ( asking me to click connect to re-authenticate my wireless connection ). I have observed this problem with a Netgear KWGR614 Router ( with the manufacturers firmware ), as well as with a TP-LINK TL-WR741ND router running OpenWrt. Taking a look at my routers logs, I find many instances of the following line: Tuesday,04 Jan 2011 03:53:01 [TCP SYN Flood][Deny access policy matched, dropping packet] I know that the Netgear router is susceptible to denial of service attacks, as I have previously been able to disrupt its operation by putting an nmap scan into a while loop. I use WEP on the Netgear router and WPA on the TP-LINK to encrypt the wireless connections. Is it possible that someone is jamming my signal ?

  • Fresh install on SSD with Ubuntu and Windows Vista, using whole disk encryption for Ubuntu

    - by nategator
    I would like to do a fresh install on a OCZ Vertex Plus R2 SSD 60GB drive I purchased on the cheap. Since the AES-encryption looks like it may not work optimally for this drive, I would like to set up a dual-boot to Windows Vista (the only Windows copy I have for clean install purposes) and Ubuntu 12.04 with the best encryption scheme possible. My plan is to have Windows around just in case I need to use a program that won't work with Wine and Ubuntu as my daily OS with all of my information secured in case the laptop is ever stolen or sold. Although this setup will not provide a lot of space, I think I can squeeze both OSes and have enough for second-computer office tasks. So, my questions are: Which OS should I install first, Ubuntu or Vista? Any special considerations when partitioning the drive? How should I install Ubuntu to ensure full disk encryption for the Linux partition(s) and or my daily computing? Is there a significant performance upgrade with doing a solo install of Ubuntu instead of a dual boot setup? Will TRIM, for example, work correctly? Are there any significant security concerns with going the route of a dual-boot, other than the fact that any activity on Windows may be fully recoverable if the drive is stolen or sold? Thanks in advance!

  • Sorting objects before rendering

    - by dreta
    I'm trying to implement a scene graph and in all the articles i've come across there is talk about object sorting. So you'd sort your objects by "material" for example. Now untill i sat down and started implementing it, i kind of took this for granted, because it made sense. But now i'm wondering what does sorting actually change? In my engine, i have a manager for UBOs, i use those to store data that'll be shared between programs, at the moment that only involves time, camera and projection matrices and lights (i'm not worrying about managing which lights affect which objects ATM). Now for each model i have to change the model to world matrix uniform, no sorting is going to change that. So is the jump from changing this matrix to also setting a material for each object that bad? I vaguely remember reading somewhere that each time you change something in the pipeline, it has to get flushed and that can cause performance issues. But for each drawing call i'm setting up a model to world matrix anyway, so what sense does it make to ever be concerned about this? BTW is there any information about whether changing a uniform and calling glBufferSubData is more (or less) expensive.

  • Everything has an Interface [closed]

    - by Shane
    Possible Duplicate: Do I need to use an interface when only one class will ever implement it? I am taking over a project where every single real class is implementing an Interface. The vast majority of these interfaces are implemented by a single class that share a similar name and the exact same methods (ex: MyCar and MyCarImpl). Almost no 2 classes in the project implement more than the interface that shares its name. I know the general recommendation is to code to an interface rather than an implementation, but isn't this taking it a bit too far? The system might be more flexible in that it is easier to add a new class that behaves very much like an existing class. However, it is significantly harder to parse through the code and method changes now require 2 edits instead of 1. Personally, I normally only create interfaces when there is a need for multiple classes to have the same behavior. I subscribe to YAGNI, so I don't create something unless I see a real need for it. Am I doing it all wrong or is this project going way overboard?

  • Stuff you learned in school, that you have never used again?

    - by Mercfh
    Obviously we learn plenty of things in our University/College/Whatever that probably don't apply to everyday use, but is there anything that stands out particularly? Maybe something that was concentrated ALOT on? For me it was def. 2 things: OO Concepts and Pointers I still use OO, but not nearly to the amount people made it out to be, i can see where it'd be useful but in my line of work we don't have huge amounts of classes, maybe a couple at most. And there certainly isn't much OO reuse (i finally figured out what that means lol) Pointers are another thing, again I can see where they'd be useful...however I barely barely ever touch them, nor do the others I work with. I guess language choice has alot to do with that but still. What about you guys? edit: For those who are asking I work for a Large Printer company, and most of the Applications we work on are Java+XML and Actionscript for "Printer Apps". But we are moving towards other languages (think like webkits and stuff). So the Code amounts per parts are quite small. I never say OO wasn't useful I just said I personally havent seen it used in my workplace much.

  • Hobbyist programmer releasing software with a donate button

    - by espais
    I'd like to start this with a disclaimer that I realize that a full, clear-cut answer should be sought out by a lawyer. I am more so curious about what other users of this community have done Say that I had a small program that I had developed for fun, that I wished to release to the public. I'll drop it out there with one of the various open-source licenses, and probably put it up on SourceForge or Git in case if anybody should ever want to fork/maintain/check out code. Also say that I wanted to accept donations for the project, with absolutely 0 expectation that people will send any money. However, if somebody donated in order to buy me a beer or a pizza for the work that they liked, I would accept gladly. The question, then, is what are the general requirements of accepting donations? Can it go into a personal account with no questions asked as a "gift," or do I need to setup an LLC to avoid any taxation issues? (US citizen here). Again, yes this should be lawyer discussed, but I also know that many projects that I see have the ability to donate, and assume that the community probably has a decent amount of experience in this regard.

  • NoSQL

    - by NoReasoning
    Last night, (Tuesday, June 28), at the KC .NET User group meeting, George Westwater gave a terrific presentation on NoSQL. The best way to define it (the best way is to see George explain it, and he says he will record his presentation and make it available through his blog – link above)  is databases  that does not use relational technology. And his point, and this is true – I have been around awhile – is that non-relational databases have been used for over 50 years in the business. He points out that Wall Street firms have been using non-relational technology ever since they started using computers. IBM still fully supports IMS, now in version 11 (12 is in beta), because these firms are still using this product and will continue to do so for a long time. Of course, like a lot of computer business technology, there are a lot of new NoSQL products available these days, simply as a reaction to the problems of scaling relational databases for internet use. As a result, it almost looks as though NoSQL is something new. And there are a lot, I mean a LOT, I mean a L-O-T , of new products out there for this technology. The best resource to cover all of these products is http://nosql-database.org/, which has a huge listing of what is available. My interest in the subject is primarily due to my interest in Windows Azure and the fact that Windows Azure storage is all non-relational, even the table storage. It is very fascinating and most of all, far cheaper than using SQL Azure for storage in the “cloud."

  • Are first-class functions a substitute for the Strategy pattern?

    - by Prog
    The Strategy design pattern is often regarded as a substitute for first-class functions in languages that lack them. So for example say you wanted to pass functionality into an object. In Java you'd have to pass in the object another object which encapsulates the desired behavior. In a language such as Ruby, you'd just pass the functionality itself in the form of an annonymous function. However I was thinking about it and decided that maybe Strategy offers more than a plain annonymous function does. This is because an object can hold state that exists independently of the period when it's method runs. However an annonymous function by itself can only hold state that ceases to exist the moment the function finishes execution. So my question is: when using a language that features first-class functions, would you ever use the Strategy pattern (i.e. encapsulate the functionality you want to pass around in an explicit object), or would you always use an annonymous function? When would you decide to use Strategy when you can use a first-class function?

  • When module calling gets ugly

    - by Pete
    Has this ever happened to you? You've got a suite of well designed, single-responsibility modules, covered by unit tests. In any higher-level function you code, you are (95% of the code) simply taking output from one module and passing it as input to the next. Then, you notice this higher-level function has turned into a 100+ line script with multiple responsibilities. Here is the problem. It is difficult (impossible) to test that script. At least, it seems so. Do you agree? In my current project, all of the bugs came from this script. Further detail: each script represents a unique solution, or algorithm, formed by using different modules in different ways. Question: how can you remedy this situation? Knee-jerk answer: break the script up into single-responsibility modules. Comment on knee-jerk answer: it already is! Best answer I can come up with so far: create higher-level connector objects which "wire" modules together in particular ways (take output from one module, feed it as input to another module). Thus if our script was: FooInput fooIn = new FooInput(1, 2); FooOutput fooOutput = fooModule(fooIn); Double runtimevalue = getsomething(fooOutput.whatever); BarInput barIn = new BarInput( runtimevalue, fooOutput.someOtherValue); BarOutput barOut = barModule(BarIn); It would become with a connector: FooBarConnectionAlgo fooBarConnector = new fooBarConnector(fooModule, barModule); FooInput fooIn = new FooInput(1, 2); BarOutput barOut = fooBarConnector(fooIn); So the advantage is, besides hiding some code and making things clearer, we can test FooBarConnectionAlgo. I'm sure this situation comes up a lot. What do you do?

  • BusEnum2 and a Minor Bug Fix

    - by Kate Moss' Open Space
    The default root bus driver, BusEnum, enumerate and active drivers one by one in synchronized manner. It is not only slowing the boot time but in the even if any of driver's init function (XXX_init) get hanged, the whole system won't boot at all. There is a sample of enhanced root bus driver, BusEnum2, on the http://msdn.microsoft.com/en-us/library/dd187254.aspx The page provides the sample code and the detail explanation of the design concept. With multi-threaded BusEnum2 on CE7 with SMP enabled system, the scalability is even more significant. Since you have more than one processor and it can load drivers in parallel! Everything looks good so far, except to there is a small bug in the sample code. Fortunately, it is easy to fix. But hard to trace if you ever enc outer it! The BUSENUM2 flag only defined in BUSENUM2\BUSDEF\sources but not in BUSENUM2\BUSENUM\sources. The DeviceFolder is implemented in BUSENUM2\BUSDEF but the instance is created in BUSENUM2\BUSENUM\busenum.cpp, so the result is it allocates less memory than actual need.   Add   CDEFINES=$(CDEFINES) -DBUSENUM2   into BUSENUM2\BUSENUM\sources and the problem fixed!
