  • Develop an android and iPhone application with shared database

    - by Bongo
    I have a great idea for smartphone application, And I want to develop an application suited for both android and iPhone. In addition I need to use spatial database for geo indexing that will be shared for both applications. I am new to this app world and I have some questions. Is there away to develop for both machines? I know java but not objective c. My guess is that I need to separate the database from the computing to support both applications. What are the best cloud computing providers with spatial database support that can host the server? Do I need 2 hosting servers or there is one server the can support the both of them? which database provider can support geo indexing and support this intergraion, I prefer providers with reasonable free quotas. Thanks.

  • Testing To Prevent Cascading Bugs

    - by jfrankcarr
    Yesterday, Twitter was hit with a "Cascading Bug" as described in this blog post: A “cascading bug” is a bug with an effect that isn’t confined to a particular software element, but rather its effect “cascades” into other elements as well. I've seen this kind of bug, on a smaller scale of course, on some projects I've worked on. They can be difficult to identify in dev/test environments, even within a test driven development environment. My questions are... What are some strategies you use, beyond the basic TDD and standard regression testing, to identify and prevent the potential trouble points that might only occur in the production environment? Does the presence of such problems indicate a breakdown in the software development process or simply a by-product of complex software systems?

  • How to write a network game?

    - by TomWij
    Based on Why is so hard to develop a MMO?: Networked game development is not trivial; there are large obstacles to overcome in not only latency, but cheat prevention, state management and load balancing. If you're not experienced with writing a networked game, this is going to be a difficult learning exercise. I know the theory about sockets, servers, clients, protocols, connections and such things. Now I wonder how one can learn to write a network game: How to balance load problems? How to manage the game state? How to keep things synchronized? How to protect the communication and client from reverse engineering? How to work around latency problems? Which things should be computed local and which things on the server? ... Are there any good books, tutorials, sites, interesting articles or other questions regarding this? I'm looking for broad answers, but specific ones are fine too to learn the difference.

  • New website, plans to go large. How do you protect yourself?

    - by John Redyns
    I'm planning to create a new site that (in hopes) will make it to a decent state of popularity and use. I have made sites before, but they weren't serious, with any intended purpose other than personal and friend use. I've never been able to find a solid post on good steps to protecting yourself, and your site/idea before you start. This site will always be free, and will not be bringing it any revenue by ads or whatnot, but I plan to in the future and would want to make I'm in the clear legally for one. Do you need to copyright anything? Or anything of the same concept as copyright? Do I make an LLC to operate it under? Apologies for this extremely poorly written question, basically I want to be both legal, and I want to make sure nobody can just rip my idea or name(s). (I'm sure this will be more concise as questions here are asked) Thanks

  • Question about server usage, big community platform

    - by Json
    I’m working on a community platform writen in PHP, MySQL. I have some questions about the server usage maybe someone can help me out. The community is based on JQuery with many ajax requests to update content. It makes 5 - 10 AJAX(Json, GET, POST) requests every 5 seconds, the requests fetch user data like user notifications and messages by doing mySQL queries. I wonder how a server will handle this when there are for more than 5000 users online. Then it will be 50.000 requests every 5 seconds, what kind of server you need to handle this? Or maybe even more, when there are 15.000 users online, 150.000 requests every 5 seconds. My webserver have the following specs. Xeon Quad 2048MB 5000GB traffic Will it be good enough, and for how many users? Anyone can help me out or know where to find such information, like make a calculation?

  • Trying to make a universe [on hold]

    - by caters
    I am wanting to program a universe so that it starts with a big bang and atoms form and then molecules form and stars start to form and planets start to form and then moons around those planets. I have a few questions. If 400 IPMUs(In Program Mass Units) = 1 solar mass than how would I calculate the number of IPMUs for a spectral class of star given the range of solar masses for a main sequence star in that spectral class? How can I have planets not look like stars? Since whether it is a subdwarf, main sequence star, subgiant, giant, bright giant, supergiant, or hypergiant is mainly dependent on the radius and luminosity how can I have the radius and luminosity independent of the mass?

  • How do I set the correct monitor resolution with Nvidia drivers for a monitor that does not send EDID?

    - by Torben Gundtofte-Bruun
    I keep having trouble getting the correct monitor resolution - every time I reinstall, I happen to use a newer Ubuntu release and the old tricks I used to know no longer work. Instead of leaving a long trail of questions for every new release, I am looking for a more universal and timeless solution. What's the correct way to set the correct monitor resolution with an Nvidia GPU for a screen that does not send EDID values? Note: This is a "dummy" question -- with the help from the chat, I already found the answer, and I am now going to add my own answer to document a solution that is hopefully universal.

  • Why is cleverness considered harmful in programming by some people?

    - by Larry Coleman
    I've noticed a lot of questions lately relating to different abstraction techniques, and answers saying basically that the techniques in question are "too clever." I would think that part of our jobs as programmers is to determine the best solutions to the problems we are given to solve, and cleverness is helpful in doing that. So my question is: are the people who think certain abstraction techniques are too clever opposed to cleverness per se, or is there some other reason for the objection? EDIT: This parser combinator is an example of what I would consider to be clever code. I downloaded this and looked it over for about half an hour. Then I stepped through the macro expansion on paper and saw the light. Now that I understand it, it seems much more elegant than the Haskell parser combinator.

  • Should I use nodindex, follow or rel canonical?

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

  • Google shows "search instead for" when searching for our website

    - by Athanatos
    Our website is new and the name is similar (only one letter different than another website) completely different type and company though. searching for xxxxxA works OK in Google and we find relatively good results. However searching xxxxxA.com finds results for the other website and gives us the following options: Showing results for xxxxxE.com Search instead for xxxxxA.com (hyperlink when clicked then it is correctly searching for our site) Questions: Do we need to contact Google to correct this and if yes how ? if not will it be corrected automatically when the site becomes more popular and what is the process? How do we make the process quicker?

  • What are the files in /dev/input/ and what they do?

    - by Pouya
    I'm fairly new to ubuntu and I've started to search around everywhere and check everything! Recently I saw these files at /dev/input/eventX, js0, mice, mouseX. By printing the output using "cat" I realized they are somehow responsible for mouse and keyboard input but the output had an strange character encoding (even for the keyboard). My questions are, what are these files and how can I interpret the data of these files? Are there any other places that I can access the input/output of my Ubuntu machine? And are there any ebooks, manual or something similar that I can check the duty and structure of ubuntu system files? (i.e. to find the answer of such question)

  • Context is Everything

    - by Angus Graham
    Normal 0 false false false EN-CA X-NONE X-NONE MicrosoftInternetExplorer4 /* Style Definitions */ table.MsoNormalTable {mso-style-name:"Table Normal"; mso-tstyle-rowband-size:0; mso-tstyle-colband-size:0; mso-style-noshow:yes; mso-style-priority:99; mso-style-qformat:yes; mso-style-parent:""; mso-padding-alt:0cm 5.4pt 0cm 5.4pt; mso-para-margin-top:0cm; mso-para-margin-right:0cm; mso-para-margin-bottom:10.0pt; mso-para-margin-left:0cm; line-height:115%; mso-pagination:widow-orphan; font-size:11.0pt; font-family:"Calibri","sans-serif"; mso-ascii-font-family:Calibri; mso-ascii-theme-font:minor-latin; mso-fareast-font-family:"Times New Roman"; mso-fareast-theme-font:minor-fareast; mso-hansi-font-family:Calibri; mso-hansi-theme-font:minor-latin;} Context is Everything How many times have you have you asked a question only to hear an answer like “Well, it depends. What exactly are you trying to do?”.  There are times that raw information can’t tell us what we need to know without putting it in a larger context. Let's take a real world example.  If I'm a maintenance planner trying to figure out which assets should be replaced during my next maintenance window, I'm going to go to my Asset Management System.  I can get it to spit out a list of assets that have failed several times over the last year.  But what are these assets connected to?  Is there any safety consequences to shutting off this pipeline to do the work?  Is some other work that's planned going to conflict with replacing this asset?  Several of these questions can't be answered by simply spitting out a list of asset IDs.  The maintenance planner will have to reference a diagram of the plant to answer several of these questions. This is precisely the idea behind Augmented Business Visualization. An Augmented Business Visualization (ABV) solution is one where your structured data (enterprise application data) and your unstructured data (documents, contracts, floor plans, designs, etc.) come together to allow you to make better decisions.  Essentially we're showing your business data into its context. AutoVue allows you to create ABV solutions by integrating your enterprise application with AutoVue’s hotspot framework. Hotspots can be defined for your document. Users can click these hotspots to trigger actions in your enterprise app. Similarly, the enterprise app can highlight the hotspots in your document based on its business data, creating a visual dashboard of your business data in the context of your document. ABV is not new. We introduced the hotspot framework in AutoVue 20.1 with text hotspots. Any text in a PDF or 2D CAD drawing could be turned into a hotspot. In 20.2 we have enhanced this to include 2 new types of hotspots: 3D and regional hotspots. 3D hotspots allow you to turn 3D parts into hotspots. Hotspots can be defined based on the attributes of the part, so you can create hotspots based on part numbers, material, date of delivery, etc.  Regional hotspots allow an administrator to define rectangular regions on any PDF, image, or 2D CAD drawing. This is perfect for cases where the document you’re using either doesn’t have text in it (a JPG or TIFF for example) or if you want to define hotspots that don’t correspond to the text in the document. There are lots of possible uses for AutoVue hotspots.  A great demonstration of how our hotspot capabilities can help add context to enterprise data in the Energy sector can be found in the following AutoVue movies: Maintenance Planning in the Energy Sector - Watch it Now Capital Construction Project Management in the Energy Sector  -  Watch it Now Commissioning and Handover Process for the Energy Sector  -  Watch it Now

  • How much configurability to give to users regarding concurrency?

    - by rwong
    This question is a narrowing-down of these related questions: How much effort should we spend to programming for multiple cores? Concurrency: How do you approach the design and debug the implementation? Given that each user's computers may have different performance characteristics with respect to calculations, memory, disk I/O bandwidth and network I/O bandwidth, and that it is difficult to implement an automated self-tuning system in your software, how much configurability should we give to the end-users so that they can find ways (by trial-and-error?) to improve our software's efficiency? If we give users the ability to change these settings, how do we give visual feedback to users so they can measure the performance changes?

  • How do I get unity back?

    - by Siva
    I got the latest driver software for my old ATI Radeon 4600, and it had me restart. My screen was then just a big terminal! I could log in, but when I typed 'unity' into it as a command, it said something about DISPLAY not found; set it to :0 (zero). I don't know enough about Linux to deal with this. I am using a DSL live CD to ask this. I looked at similar questions suggested, even searched. If my question's a duplicate, I apologise, but I didn't understand what I saw there. T_T

  • Windows Phone 8 detected as mass storage

    - by legends2k
    From version 8 onwards Windows Phone supports MTP (media transfer protocol) to transfer audio and I thought I could use Rhythmbox to upload music onto my device. Thing is Rhythmbox doesn't display the device under Devices pane (there's no Device pane for that matter). I searched other questions here and tried out installing mtp-tools, mtpfs and also tried gMTP, which doesn't seem to detect the device as a portable player. I see that the device's icon looks like a Camera in dash bar and when I see the address location, it shows gphoto2://[usb:002,013]/, which makes me doubt that it's detected as a camera or as a mass storage device. /.gvfs/gphoto2 mount on usb%3A002,003 is where the actual mount is. What do I do to fix this? I tried creating .is_audio_player too.

  • PHP composer question

    - by kdub
    just getting started with composer and I have a couple of questions. When I use composer to add a dependency, the dependency gets added to my folder's Vendor directory. The newly added package not only comes with the source code for that package, but all packagist required files for the developer to test and add that package to packagist repo (composer.json, .travis.yaml, license, readme.md, etc). For my project, do I need to keep the vendor's required packagist files in my project? Can I clean the package folder structure up a little? I added the package, Slim micro framework, which nests the source files three directories deep upon installation, ../vendor/slim/slim/Slim/(source Files). Is it worth moving these files to the top Slim directory like: ../vendor/Slim/(source files)? Or will this ruin the integrity of the package?

  • Doing practice jobsearch/technical interviews?

    - by Beekguk
    I graduated college last year & I've never gone through the interview process - my current programming position evolved out of projects I did in school, but in a few months I'm making a clean break and moving across the country so I'm going to have to face a "grown-up" jobsearch. I'm kind of scared of technical interviews - I think I'm pretty good at my job and my hobby programming projects ... but what if it turns out I'm part of that group that thinks they're qualified, but really just cause despair at the state of education in the hearts of interviewers? So, I'm thinking of doing a "practice" job hunt in my current city to get an idea of what it's like and what kind of experience/expertise employers are really looking for. Is this a dick move ethically (applying to/interviewing for jobs I can't take)? If so, is there another good way to prepare for technical interviews, especially those little trick puzzle-type questions?
