  • How to implement soft edge areas with particles

    - by OpherV
    My game is created using Phaser, but the question itself is engine-agnostic. In my game I have several environments, essentially polygonal areas that player characters can move into and be affected by. For example ice, fire, poison etc' The graphic element of these areas is the color filled polygon area itself, and particles of the suitable type (in this example ice shards). This is how I'm currently implementing this - with a polygon mask covering a tilesprite with the particle pattern: The hard edge looks bad. I'd like to improve by doing two things: 1. Making the polygon fill area to have a soft edge, and blend into the background. 2. Have some of the shards go out of the polygon area, so that they are not cut in the middle and the area doesn't have a straight line for example (mockup): I think 1 can be achieved with blurring the polygon, but I'm not sure how to go about with 2. How would you go about implementing this?

  • Screen Brightness not adjustable for Acer Aspire S3

    - by Kakadu90
    First of all, thank you very much for providing this useful forum. Too bad for me, there is no support for the Acer Aspire S3 yet (just came out in October) Short Description of the Problem: I cannot adjust the screen brightness. Neither Compiz nor the FN Key combination work. Also the fan keeps running on full power. As you can guess, both of these drain my battery. The Setup: Acer Aspire S3, Intel i5 newest Generation, Intel HD3000 Grafic Accelerator (no driver maybe?) Thanks in advance, Kakadu90

  • failure to restore backup from deja dup

    - by Layla Kosakov
    I had ubuntu 12.04.1 and I made a backup with deja dup of the home folder in an external hard disk. Today I installed ubuntu 14.4 and erased the ubuntu 12.04.1. Now I'm trying to restore my back up. First it ask where is the back up to restore, then it ask of what date to restore, and then it starts, after a wile ask for the password. I put the password and it says Restoring and stays in preparing with out any advancement. Don't show any error, just stays preparing. The window of details is in white. I had all my documents... it's very bad for me, all my personal data... lost? Thanks for any help, Layla.

  • Wireless USB Adapter driver configuration

    - by Jones
    First I would like agree one thing that this is fully for Ubuntu, not for BackTrack. However I'm posting my BackTrack question here since I find similar problems in backtrack forum are being unanswered and Linux/Unix site of StackExchange has very low attraction. I'm having USB wifi adapter (iBall Baton), having chipset RTL8191SU. It displays available wifi networks in Wicd manager. But while trying to connect it gives me bad password. When I'm trying to run airmon-ng it didn't returned me the monitor mode. I tried to replace with Ubuntu 12.10 drivers. But it totally nulled the device functionality. However I restored the drivers. I'm interested to compile drivers as if anyone indicate the methods. Awaiting ideas!

  • How to improve testing your own code

    - by Peter
    Today I checked in a change on some code which turned out to be not working at all due to something rather stupid yet very crucial. I feel really bad about it and I hope I finally learn something from it. The stupid thing is, I've done these things before and I always tell myself, next time I won't be so stupid... Then it happens again and I feel even worse about it. I know you should keep your chin up and learn from your mistakes but here's the thing: I try to improve myself, I just don't see how I can prevent these things from happening. So, now I'm asking you guys: Do you have certain groundrules when testing your code?

  • Suspend/hibernate doesn't work on an Asus Laptop

    - by b1ackjosh
    I'm having issues suspending 11.04 on my new Asus U30sd-XA1 laptop, it's a new laptop on the market and I'm wondering if anyone else has had this issue and maybe have a fix for it. Basically whenever I close or put the laptop to sleep the screen goes black but the video card doesn't actually turn off, then the fan spins up even faster then it was before and gets hot. I did see that some people were having similar issues on other laptops and they set the kernal back. I'm newish to ubuntu and I'm not super comfortable messing with the kernal. If anyone has any other solutions that would be great. I am not using the 520m nvidia driver because it won't load unity after it's installed. I've also heard quite a few bad things about the drivers on the ubuntu forums, so I deactivated the driver.

  • Design documents as part of Agile

    - by syrion
    At my workplace, we face a challenge in that "agile" too often has meant "vague requirements, bad acceptance criteria, good luck!" We're trying to address that, as a general improvement effort. So, as part of that, I am proposing that we generate design documents that, above and beyond the user story level, accurately reflect the outcome of preliminary investigations of the effect of a given feature within the system and including answers to questions that we have asked the business. Is there an effective standard for this? We currently face a situation where a new feature may impact multiple areas in our "big ball of mud" system, and estimates are starting to climb due to this technical debt. Hopefully more thoughtful design processes can help.

  • Right multi object dependance design

    - by kenny
    I need some help with a correct design. I have a class called BufferManager. The push() method of this class reads data from a source and pushes it to a buffer repeatedly until there is no more data left in the source. There are also consumer threads that read data from this buffer, as soon as new data arrives. There is an option to sort the data before it comes to buffer. What I do right now is that BufferManager, instead of pushing data to the buffer, pushes it to another "sorting" buffer and starts a sorting thread. SorterManager class reads the data, sorts it in files and push()es the sorted data into the buffer. There will be a bottleneck (I use merge sort with files) but this is something I can't avoid. This is a bad design, because both BufferManager and SorterManager push data to a buffer (that consumers read from). I think only BufferManager should do it. How can I design it?

  • Constructive criticism for my bounce rate being so high [closed]

    - by Daniel
    The bounce rate on my website's product pages is 80%, which is terrible. Could you offer any opinions on whether you consider the user experience to be bad, and how I could possibly improve it? Other pages, such as the home and category pages, have acceptable bounce rates, but the vast majority of my traffic lands on the product pages. I already tried removing some Google ads for a couple of days, but this didn't seem to help at all. I'm working on doing A/B testing at the moment. (It's tricky, as the site is based on a CMS - I custom coded the [Joomla] component, so hopefully I can get this testing working.)

  • Would google consider this a "link scheme"?

    - by Abe Miessler
    I work for a County Government. In an effort to improve our search engine rankings I was considering contacting some of the other Counties in my state and seeing if we could setup an arrangement where we link to them and they link to us. It seems like a reasonable thing to have a "Other Counties" page with various links on a County website, but it also seems like it's bordering on a link scheme according to Google. When I read Google's article about link schemes it seems like we hit some of the right reasons for having links on another County's site but also some of the wrong. Does anyone have any insight into whether this is a good or bad idea?

  • Structure vs. programming

    - by ChristopherW
    Is it bad that I often find myself spending more time on program structure than actually writing code inside methods? Is this common? I feel I spend more time laying the foundation than actually building the house (metaphorically). While I understand that without a good foundation the house will cave in, but does it legitimately need to take half of the project to finalize code structure? I understand design patterns, and I know where to go if I need help on choosing one, but often I find myself doubting my own choices.

  • How to protect Ubuntu from fork bomb

    - by dblang
    I heard someone talking about a fork bomb, I did some research and found some dreadful information about some strange looking characters people can have you type at the command line and as a result do bad things on the computer. I certainly would not issue commands I do not understand but one never knows what can happen. I heard that some OS allows the administrator to place some limit on user processes to mitigate the effects of fork bombs, is this protection in Ubuntu by default or would a person with sudo privilege have to set this? If so, how?

  • HTG Explains: How the SmartScreen Filter Works in Windows 8

    - by Chris Hoffman
    Windows 8 includes a SmartScreen filter that prevents unknown and malicious programs from running. SmartScreen is part of Internet Explorer 8 and 9 – with Windows 8, it’s now integrated into the operating system. SmartScreen is a useful security feature that will help prevent bad applications from running, but it may occasionally prevent a legitimate application from running. SmartScreen reports some information to Microsoft, so it may have some privacy implications. HTG Explains: Is ReadyBoost Worth Using?

  • Attaining credit card data

    - by Adam
    I've read the many posts on this site that say we are not allowed to store cc numbers if we are not pci-compliant. But, I'm wondering if it is possible to send a CC number through a form to an email address? Would that be still infringing on the standards? The reason I ask is that a local business owner wants to retrieve a number through a form on his website, so he can manually enter the cc info on his end. I'm assuming the only way to properly get a credit card number is to setup a merchant account? What's the best way to get a cc number without calling the actual customer? I'm thinking email is a bad idea as well.

  • How do you think the industry for programmers is right now? [closed]

    - by Mercfh
    I recall 5-6 years ago there was quite a slump in jobs, but 5-6 years ago I was just starting college so I was oblivious to what was going on, however I had heard about it at many places. And obviously there's the recession that we are in now (although I've been told things have been getting better). So what's the job outlook for programmers right "now"? Good? Bad? Average? When I was looking for a job 2 months ago I "saw" quite a bit of job openings near my city, but that could've just been me living in a lucky "growing" area.

  • Panda 4: Reducing #indexed pages. How much is enough?

    - by Noam
    I've been hit by panda 4 (40% decrease). I didn't see any change during panda 1-3. From what I've read it and when compared to my site, the change is probably due to the fact that I have over 30M pages indexed on Google, and they've starting seeing that as some sort of bad indication. Although I feel all of the pages have a unique value that Google should crawl, it seems I should make some tough calls and deduce the indexed pages according to some prioritization I will conduct. The question is what should be my target, or what factors should help me figure out a relevant target. How many pages should I try to reduce to? - 25M - 15M - 1M - 2000 Is it enough to add noindex to low priority pages or should I also remove all internal linking to them?

  • "PHP: Good Parts"-ish book / reference

    - by julkiewicz
    Before I had my first proper contact with Javascript I read an excellent book "Javascript: The Good Parts" by Douglas Crockford. I was hoping for something similar in case of PHP. My first thought was this book: "PHP: The Good Parts" from O'Reilly However after I read the reviews it seems it totally misses the point. I am looking for a resource that would: concentrate on known shortcommings of PHP, give concrete examples, be as exhaustive as possible I already see that things can go wrong. If you want to close this question: Please consider this, I looked through SO, and Programmers for materials. I obviously found this question: http://stackoverflow.com/questions/90924/what-is-the-best-php-programming-book It's general, mine is specific. Moreover I'm reading the top recommendation "PHP Objects, Patterns, and Practice" right now. I find it insufficient -- it doesn't address the bad practices as much as I would like it to. tl;dr My question is NOT a general PHP book request.

  • Finding it Hard to Deliver Right Customer Experience: Think BPM!

    - by Ajay Khanna
    Our relationship with our customers is not a just a single interaction and we should not treat it like one. A customer’s relationship with a vendor is like a journey which starts way before customer makes a purchase and lasts long after that. The journey may start with customer researching a product that may lead to the eventual purchase and may continue with support or service needs for the product. A typical customer journey can be represented as shown below: As you may notice, customers tend to use multiple channels to interact with a company throughout their journey.  They also expect that they should get consistent experience, no matter what interaction channel they may choose. Customers do not like to repeat the information they have already provided and expect companies to remember their preferences, and offer them relevant products and services. If the company fails to meet this expectation, customers not only will abandon the purchase and go to the competitor but may also influence others’ purchase decision. Gone are the days when word of mouth was the only medium, and the customer could influence “Six” others. This is the age of social media and customer’s good or bad experience, especially bad get highly amplified and may influence hundreds of others. Challenges that face B2C companies today include: Delivering consistent experience: The reason that delivering consistent experience is challenging is due to fragmented data, disjointed systems and siloed multichannel interactions. Customers tend to get different service quality if they use web vs. phone vs. store. They get different responses from different service agents or get inconsistent answers if they call sales vs. service group in the company. Such inconsistent experiences result in lower customer satisfaction or NPS (net promoter score) numbers. Increasing Revenue: To stay competitive companies frequently introduce new products and services. Delay in launching such offerings has a significant impact on revenue realization. In addition to new product revenue, there are multiple opportunities to up-sell and cross-sell that impact bottom line. If companies are not able to identify such opportunities, bring a product to market quickly, or not offer the right product to the right customer at the right time, significant loss of revenue may occur. Ensuring Compliance: Companies must be compliant to ever changing regulations, these could be about Know Your Customer (KYC), Export/Import regulations, or taxation policies. In addition to government agencies, companies also need to comply with the SLA that they have committed to their customers. Lapse in meeting any of these requirements may lead to serious fines, penalties and loss in business. Companies have to make sure that they are in compliance will all such regulations and SLA commitments, at any given time. With the advent of social networks and mobile technology, companies not only need to focus on process efficiency but also on customer engagement. Improving engagement means delivering the customer experience as the customer is expecting and interacting with the customer at right time using right channel. Customers expect to be able to contact you via any channel of their choice (web, email, chat, mobile, social media), purchase via any viable channel (web, phone, store, mobile). Customers expect companies to understand their particular needs and remember their preferences on repeated visits. To deliver such an integrated, consistent, and contextual experience, power of BPM in must. Your company may be organized in departments like Marketing, Sales, Service. You may hold prospect data in SFA, order information in ERP, customer issues in CRM. However, the experience delivered to the customer must not be constrained by your system legacy. BPM helps in designing the right experience for the right customer and integrates all the underlining channels, systems, applications to make sure right information will be delivered to the right knowledge worker or to the customer every single time.     Orchestrating information across all systems (MDM, CRM, ERP), departments (commerce, merchandising, marketing service) and channels (Email, phone, web, social)  is the key, and that’s what BPM delivers. In addition to orchestrating systems and channels for consistency, BPM also provides an ability for analysis and decision management. By using data from historical transactions, social media and from other systems, users can determine the customer preferences, customer value, and churn propensity. This information, in the context, is then used while making a decision at a process step. Working with real-time decision management system can also suggest right up-sell or cross-sell offers, discounts or next-best-action steps for a particular customer. Timely action on customer issues or request is also a key tenet of a good customer experience. BPM’s complex event processing capabilities help companies to take proactive actions before issues get escalated. BPM system can be designed to listen to a certain event patters then deduce from those customer situations (credit card stolen, baggage lost, change of address) and do a triage before situation goes out of control. If such a situation arises you can send alerts to right people or immediately invoke corrective actions. Last but not least one of BPM’s key values is to drive continuous improvement. Learning about customers past experiences, interactions and social conversations, provide valuable insight. Such insight can be used to improve products, customer facing processes, and customer experience. You may take these insights as an input to design better more efficient and customer friendly sales, contact center or self-service processes. If customer experience is important for your business, make sure you have incorporated BPM as a part of your strategy to design, orchestrate and improve your customer facing processes.

  • ejabberd won't look at my host_config option

    - by John
    I'm new with ejabberd. What I want is to have a host myhost.domain.com which has an ldap authentication method. This all works fine if i modify the global options in AUTHENTICATION section in my ejabberd.cfg file. I am able to create two clients( defined in my LDAP directory ), and comunicate between them. Like i said, this works fine. But by aplying this authentication method globaly, it means that every hostname that i declare must use that. So i'm looking at {host_config, "myhost.domain.com" ...} But somehow i can't get ejabberd to look at that configuration, it just skips it. If i declare it like: {xhost_config, ...}, than in my ejabberd.log file i get a bad return error( so it knows that the configuration is there, but it won't look at it). Any suggestions? Thanks.

  • administering new website - Found really tiny keywords inside page

    - by ndefontenay
    I'm administering this new website. The previous web admin included a large amount of tiny keywords on top of some of its pages. I've removed them already. I need to know if I have to rest the domain with google webmaster or will google notice the change and take action? thanks in advance. edit: They are not meta keyword. They are literally text so small that it looks like a fine line of gibberish on the page itself. This clearly violates google guidelines. My point was more: Do I need to tell google that we are not bad pupils anymore.
