  • creating a tag-based website and not using programming?

    - by monodial
    I want to create a tag-based website, and I need a tool that I could use (preferably without programming). It's a site where a user could pick tags on a certain item. All tags will be placed under a group that they are logically linked to (I will do that by hand). On the other end - a visitor could choose a tag, and then be redirected to a few items on which that tag was selected the most. Besides this, I need to set up a registration form (for the visitors who want to select tags on a desired item). stackoverflow.com may serve as an example of what I want to achieve. Functionally it is a quite similar approach. I am not sure if further detailing will bring me closer to getting a development advice, but nevertheless - following this template what I would be missing on is: ability to categorize the tags; and so they would fit in one page (overall i assume <200 tags) box where a user could enter a tag and it would be pending until a certain number of users enter such tag ability to limit the number of 'questions' that appear when a visitor chooses a tag - 'question' stands for an item to which users are selecting tags (displayed items would depend on the frequency the tag was assigned - say the top two items) Which software should I try / How should I go about it? Thank you. Lukas P.S. I have bought hosting account through GoDaddy.com. This is a first website that I am trying to build.

  • Implementing new required feature after software release

    - by TiagoBrenck
    Fake Scenario There is a software that was released 1 year ago. The software is to map and register all kind of animals on our planet. When the software was released, the client only needed to know the scientific name of the animal, a flag if it is in risk of extinction and a scale of dangerous(that is a fake software and specification, I don't want to discuss this here). There are already 100.000 animals records saved on DB. New Feature One year later, the client wants a new feature. It is really important to him to know the animals classes, and this is a required field. So he asks me to put a field to input the animal class, and this field is required. Or maybe where this animal was discovered. Problem I have already 100.000 recorded animals without a class or where it was discovered, but I need to insert a new column to storage this information and this column can't be null. I don't have a default value for this situation (there isn't a default animal class or where it was discovered). I don't want to keep the requirement rule only on my software, my DB must have this requirement too(I like to keep business rules on DB too). What are the alternatives to solve this situation? I am on a situation that this new feature cannot be previewed or reviewed for the existing records. The time already passed and I can't go back on time to get it

  • Ubuntu won't load, freezes on purple screen

    - by kara
    Last time I restarted my computer, I could not get Ubuntu to load; the screen would either go black, or would hang at the purple screen indefinitely. I have had some graphics problems in the past, but had put 'nomodeset' after 'quiet splash' in the grub command line, which at least let Ubuntu load. That doesn't work now, and doesn't work if I remove it. I looked up some answers, such as this one: Purple start screen - no splash screen However, when I enter the root in recovery mode in grub, I always get errors when I run those command lines and it won't let me modify the files. Also, if I run in recovery mode and then choose 'resume normal boot', it will continue. But instead of getting a usual interface, I get a black screen that asks for my username and password. I enter these, and it tells me I'm in Ubuntu 12.04, but I'm still on a black screen with texts. It also informs me that there are updates to install. When I use the command 'sudo apt-get update', it starts to retrieve the information, but then the screen goes blank after a couple of seconds and I can't do anything anymore. Any ideas?

  • Best way to mask 2D sprites in XNA?

    - by electroflame
    I currently am trying to mask some sprites. Rather than explaining it in words, I've made up some example pictures: The area to mask (in white) Now, the red sprite that needs to be cropped. The final result. Now, I'm aware that in XNA you can do two things to accomplish this: Use the Stencil Buffer. Use a Pixel Shader. I have tried to do a pixel shader, which essentially did this: float4 main(float2 texCoord : TEXCOORD0) : COLOR0 { float4 tex = tex2D(BaseTexture, texCoord); float4 bitMask = tex2D(MaskTexture, texCoord); if (bitMask.a > 0) { return float4(tex.r, tex.g, tex.b, tex.a); } else { return float4(0, 0, 0, 0); } } This seems to crop the images (albeit, not correct once the image starts to move), but my problem is that the images are constantly moving (they aren't static), so this cropping needs to be dynamic. Is there a way I could alter the shader code to take into account it's position? Alternatively, I've read about using the Stencil Buffer, but most of the samples seem to hinge on using a rendertarget, which I really don't want to do. (I'm already using 3 or 4 for the rest of the game, and adding another one on top of it seems overkill) The only tutorial I've found that doesn't use Rendertargets is one from Shawn Hargreaves' blog over here. The issue with that one, though is that it's for XNA 3.1, and doesn't seem to translate well to XNA 4.0. It seems to me that the pixel shader is the way to go, but I'm unsure of how to get the positioning correct. I believe I would have to change my onscreen coordinates (something like 500, 500) to be between 0 and 1 for the shader coordinates. My only problem is trying to work out how to correctly use the transformed coordinates. Thanks in advance for any help!

  • WiFi slow sometimes, reboot helps, how do I debug it?

    - by January
    Ubuntu 12.04.1 with all updates installed. Laptop Lenovo Thinkpad X230 with Intel Corporation Centrino Advanced-N 6205. WiFi sometimes becomes extremely slow. Often this occurs when I wake the system from suspend and connect to a different network. I find no obvious clues in system logs. /etc/init.d/network-manager restart doesn't help, but a reboot does. How can I go on with debugging this issue? In specific, which parts of the system should I try to restart (without a complete reboot)? I know of problems with Intel WiFi (see for example this question and the instructions here), but if that was the problem, I would expect the WiFi to be slow at all times, and not just sometimes. Also, I have a gut feeling that it might be a DNS issue (for example, getting a page from a known server is faster than accessing a new server), but I don't know how to tackle it. Update: despite numerous updates in the meanwhile, I still observe this behavior. It happens always when I access my WiFi router at home after returning from work; when I reboot my laptop, the connection speed is good again.

  • Advice on designing web application with a 40+ year lifetime

    - by user2708395
    Scenario Currently, I am apart of a health care project whose main requirement is to capture data with unknown attributes using user generated forms by health care providers. The second requirement is that data integrity is key and that the application will be used for 40+ years. We are currently migrating the client's data from the past 40 years from various sources (Paper, Excel, Access, etc...) to the database. Future requirements are: Workflow management of forms Schedule management of forms Security/Role based management Reporting engine Mobile/Tablet support Situation Only 6 months in, the current (contracted) architect/senior programmer has taken the "fast" approach and has designed a poor system. The database is not normalized, the code is coupled, the tiers have no dedicated purpose and data is starting to go missing since he has designed some beans to perform "deletes" on the database. The code base is extremely bloated and there are jobs just to synchronize data since the database is not normalized. His approach has been to rely on backup jobs to restore missing data and doesn't seem to believe in re-factoring. Having presented my findings to the PM, the architect will be removed when his contract ends. I have been given the task to re-architect this application. My team consists of me and one junior programmer. We have no other resources. We have been granted a 6-month requirement freeze in which we can focus on re-building this system. I suggested using a CMS system like Drupal, but for policy reasons at the client's organization, the system must be built from scratch. This is the first time that I will be designing a system with a 40+ lifespan. I have only worked on projects with 3-5 year lifespans, so this situation is very new, yet exciting. Questions What design considerations will make the system more "future proof"? What experiences have you had in designing such systems - both failures and successes? What questions should be asked to the client/PM to make the system more "future proof"?

  • What is a "Technical Programmer"? [closed]

    - by Mike E
    I've noticed in job posting boards a few postings, all from European companies in the games industry, for a "Technical Programmer". The job description in both was similar, having to do with tools development, 3d graphics programming, etc. It seems to be somewhere between a Technical Artist who's more technical than artist or who can code, and a Technical Director but perhaps without the seniority/experience. Information elsewhere on the position is sparse. The title seems redundant and I haven't seen any American companies post jobs by that name exactly. One example is this job posting on gamedev.net which isn't exactly thorough. In case the link dies: Subject: Technical Programmer Frictional Games, the creators of Amnesia: The Dark Descent and the Penumbra series, are looking for a talented programmer to join the company! You will be working for a small team with a big focus on finding new and innovating solutions. We want you who are not afraid to explore uncharted territory and constantly learn new things. Self-discipline and independence are also important traits as all work will be done from home. Some the things you will work with include: 3D math, rendering, shaders and everything else related. Console development (most likely Xbox 360). Hardware implementations (support for motion controls, etc). All coding is in C++, so great skills in that is imperative. As I mentioned, the job title has appeared from European companies so maybe it goes by another title in America. What other titles might this specialization of programmer go by?

  • Which Ubuntu linux kernel tree matches my installed kernel?

    - by Rmano
    Answering a recent question, and before that, trying to see if a patch which is fundamental for my machine had been included in a kernel release, I have found the following problem: How can I match the kernel version I have for my kernel, which is [:~] % uname -a Linux samsung-romano 3.13.0-29-generic #53-Ubuntu SMP Wed Jun 4 21:00:20 UTC 2014 x86_64 x86_64 x86_64 GNU/Linux with the exact kernel source, which I suppose should be stored in http://kernel.ubuntu.com/git?p=ubuntu/linux.git;a=summary? In that page there are quite a lot of tags, for example: But none of them correspond to 3.13.0-29 which is my running kernel right now. The mapping should be in https://wiki.ubuntu.com/Kernel/Dev/ExtendedStable, where it is said that the 3.13 Ubuntu kernel is based on 3.13.11 --- I think. But from there to finding the tree I have installed is not straightforward. Notice: I know I can install the kernel source corresponding with my installed kernel. But I do not want to install them; I would like ti have a pointer to the git tree to be able to browse it online (and check for commits, patches, etc.). The best options seems to go to linux3.13-y.review or linux3.13-y.queue, but I am unable to find where this tree are marked for the release - if I understand well the policy, in -review the patches are accumulated for testing, and in -queue accumulated for the next minor release/update --- but I am unable to find the exact release tree. I mean, a tag equivalent to 3.13.0-29 was cut here.

  • Facebook Payments & Credits vs. Real-World & Charities

    - by Adam Tannon
    I am having a difficult time understanding Facebook's internal "e-commerce microcosm" and what it allows Facebook App developers to do (and what it restricts them from doing). Two use cases: I'm an e-com retailer selling clothes and coffee mugs (real-world goods) on my website; I want to write a Facebook App that allows Facebook users to buy my real-world goods from inside of Facebook using real money ($ USD) I'm highschool student trying to raise money for my senior class trip and want to build a Facebook App that allows Facebook users to donate to our class using real money ($ USD) Are these two scenarios possible? If not, why (what Facebook policies prohibit me from doing so)? If so, what APIs do I use: Payments or Credits? And how (specifically) would it work? Do Facebook Users have to first buy "credits" (which are mapped to $ USD values under the hood) and pay/donate with credits, or can they whip out their credit card and pay/donate right through my Facebook App? I think that last question really summarizes my confusion: can Facebook users enter their credit card info directly into Facebook Apps, or do you have to go through Payments/Credits APIs as a "middleman"?

  • Sharing password-protected videos on social media

    - by PaulJ
    We are developing a site where users will be able to watch and download videos that they've recorded of themselves in a public event. The videos will be password protected, and will be available only to users who have paid for them at the event... ...But on the other hand, we also want users to share those videos on social media, since they will be an attractive publicity for our events. Having people log into our site with their password, download the video and then re-upload it to Youtube/Facebook will be too cumbersome, and I suspect that few users will be willing to do that. So the obvious alternative is to have one of those convenient "share" buttons, but the problem with that approach will be that: The video will be physically hosted (and linked to) in our site. What happens if those videos go viral and our bandwidth cost explodes? The video is password protected. The solution I've thought of for this is: Upload the user's video to our (password-protected site) and to Youtube at the same time, as an unlisted video. The user can access our site with his password and download his video (to watch on his TV or whatever). If the users hits the "share" button, we show him the Youtube link... and we turn the video into a listed one. This seems in line with the ideas in Using YouTube as a CDN, and there didn't seem to be any objections in that question. I'm posting this just to confirm that my idea doesn't violate any Youtube TOS, and also to see if it is a good one or there might be better alternatives.

  • ASP.NET Webforms developers and web designers: how to interact?

    - by just_name
    I'm an ASP.NET Webforms developer, and I face some problems when I deal with designers. Designers always complain about the asp.net server controls. They'd rather just have an html file and create css files along with the required images to go with those. Sometimes, if the design phase is done in advance, I get html files with related css files, but then we face many problems integrating the design with the aspx files (sever controls an telerik controls ... etc). What I want to ask about is: How do I overcome these problems? The designers prefer php- and mvc developers because of the problems with .net server controls. I need to know how to interact with the designers in the correct way. Are there any tools or applications to provide the designers with the rendered (html page) of the .aspx pages? By that I mean the page in runtime rather than the aspx in Visual Studio. They do use Web Expression but they want the rendered page in html as well.

  • Dreaded SQLs

    - by lavanyadeepak
    Dreaded SQLs We used to think that a SQL statement without a where clause is only dangerous right since running that on a server TSQL is just going to impact the entire table like waving the magic wand. For that reason we should cultivate the habit first to write the statement as select and then to modify the select portion as update. Within the T-SQL Window, I would normally prefer the following first: select * from employee where empid in (4,5) and then once I am satisfied with the results, I would go ahead with the following change: --select * delete from employee where empid in (4,5) Today I just discovered another coding horror. This would typically be applicable in a stored procedure and with respect to variable nomenclature. It is always desirable to have a suitable nomenclature for parameters distinct from the column names and internal variables. This would help quicker debugging of the stored procedures besides enhancing the readability. Else in a quick bout of enthusiasm a statement like   if (@CustomerID = @CustomerID) [when the latter is intended to denote the column name and there is a superflous @ prepended], zeroing in on the problem would be little tricky. Had there been a still powerful nomenclature rules then debugging would have been more straight-forward and simpler right?

  • How can I get the best performance for playing games?

    - by Oli
    I've been playing a couple of Wine-games today and decided to switch to metacity to see what the performance difference was like. If you've never done it before, you just run metacity --replace but don't do that if you use Unity! Anyway, surprise surprise it was like playing on a dedicated Windows gaming machine. Playing under metacity today was bliss. Much higher framerates and just a fluidity that you'd expect from a native game. I'm not sure I can go back. Switching to metacity is no hardship but I wonder if there's anything else in the WM landscape that I should try out. I'm essentially looking for suggestions for the best way to play games. Mix up WMs, dedicated X sessions, whatever... As long as it makes Wine games run faster. Small print One process per answer (eg: New X session + OpenBox) We should probably land on a benchmark so we can show percentage improvement over a stock Compiz desktop. I'm open to suggestions in the comments. If people could test it and submit their how much it improves things for them in the comments, that would give others a good idea of if it's worth the pain.

  • Using mod_speling with multi-level htaccess and rewriterules

    - by michaelcgorman
    We recently switched formats for managing our 301s. For the most part, everything went well, but it seems to have stopped mod_speling from working properly. Here's what we changed: old /var/www/html/.htaccess: RewriteEngine on RewriteBase / # Change SHTML to HTML RewriteRule ^(.*)\.shtml$ $1.html [R=permanent,L] # Change PCF to HTML ('cause, you know, we probably have CMS users like that...) RewriteRule ^(.*)\.pcf$ $1.html [R=permanent,L] # Force WWW subdomain for all requests RewriteCond %{HTTP_HOST} !^www.example.edu$ [NC] RewriteRule ^(.*)$ http://www.example.edu/$1 [R,L] # User accounts are on sun.example.edu RedirectMatch ^/~(.*)$ http://sun.example.edu/~$1 # Remove index.html at the end of URLs RewriteCond %{REQUEST_URI} ^(.*/)index\.html$ [NC] RewriteRule . %1 [R=301,NE,L] Redirect 301 /academics/calendar2012-13.html http://www.example.edu/academics/calendar.html Redirect 301 /academics/departments/ http://www.example.edu/majors/ Redirect 301 /academics/Pre-Medical.pdf http://www.example.edu/academics/Pre-Medicine.pdf Redirect 301 ... new /var/www/html/.htaccess: RewriteEngine on RewriteBase / # Change SHTML to HTML RewriteRule ^(.*)\.shtml$ $1.html [R=permanent,L] # Change PCF to HTML ('cause, you know, we probably have CMS users like that...) RewriteRule ^(.*)\.pcf$ $1.html [R=permanent,L] # Force WWW subdomain for all requests RewriteCond %{HTTP_HOST} !^www.example.edu$ [NC] RewriteRule ^(.*)$ http://www.example.edu/$1 [R,L] # User accounts are on sun.example.edu RedirectMatch ^/~(.*)$ http://sun.example.edu/~$1 # Remove index.html at the end of URLs RewriteCond %{REQUEST_URI} ^(.*/)index\.html$ [NC] RewriteRule . %1 [R=301,NE,L] RewriteCond %{REQUEST_FILENAME} !-f RewriteCond %{REQUEST_FILENAME} !-d RewriteRule ^(.*) 404/$1 And then we added a new file at /var/www/html/404/.htaccess: RewriteEngine on RewriteBase /404 RewriteRule ^academics/calendar2012-13.html$ /academics/calendar.html [R=302,L] RewriteRule ^academics/departments/$ /majors/ [R=301,L] RewriteRule ^academics/Pre-Medical.pdf$ /academics/Pre-Medicine.pdf[R=301,L] RewriteRule ... I do have (Webmin-based) access to the httpd.conf (though we don't want to store all our 301s there, if possible). We're running Apache 2.2.15 on RHEL 6 on a server in our own data center. Like I said, the only problem we're seeing is that mod_speling isn't doing its magic anymore. The new format has so many advantages over the old that we really don't want to go back, but mod_speling is so nice to have that we'd also really like it to work if possible. Any ideas for how we might be able to fix mod_speling?

  • Functions that only call other functions. Is this a good practice?

    - by Eric C.
    I'm currently working on a set of reports that have many different sections (all requiring different formatting), and I'm trying to figure out the best way to structure my code. Similar reports we've done in the past end up having very large (200+ line) functions that do all of the data manipulation and formatting for the report, such that the workflow looks something like this: DataTable reportTable = new DataTable(); void RunReport() { reportTable = DataClass.getReportData(); largeReportProcessingFunction(); outputReportToUser(); } I would like to be able to break these large functions up into smaller chunks, but I'm afraid that I'll just end up having dozens of non-reusable functions, and a similar "do everything here" function whose only job is to call all these smaller functions, like so: void largeReportProcessingFunction() { processSection1HeaderData(); calculateSection1HeaderAverages(); formatSection1HeaderDisplay(); processSection1SummaryTableData(); calculateSection1SummaryTableTotalRow(); formatSection1SummaryTableDisplay(); processSection1FooterData(); getSection1FooterSummaryTotals(); formatSection1FooterDisplay(); processSection2HeaderData(); calculateSection1HeaderAverages(); formatSection1HeaderDisplay(); calculateSection1HeaderAverages(); ... } Or, if we go one step further: void largeReportProcessingFunction() { callAllSection1Functions(); callAllSection2Functions(); callAllSection3Functions(); ... } Is this really a better solution? From an organizational point of view I suppose it is (i.e. everything is much more organized than it might otherwise be), but as far as code readability I'm not sure (potentially large chains of functions that only call other functions). Thoughts?

  • Extreme Portability: OpenJDK 7 and GlassFish 3.1.1 on Power Mac G5!

    - by MarkH
    Occasionally you hear someone grumble about platform support for some portion or combination of the Java product "stack". As you're about to see, this really is not as much of a problem as you might think. Our friend John Yeary was able to pull off a pretty slick feat with his vintage Power Mac G5. In his words: Using a build script sent to me by Kurt Miller, build recommendations from Kelly O'Hair, and the great work of the BSD Port team... I created a new build of OpenJDK 7 for my PPC based system using the Zero VM. The results are fantastic. I can run GlassFish 3.1.1 along with all my enterprise applications. I recently had the opportunity to pick up an old G5 for little money and passed on it. What would I do with it? At the time, I didn't think it would be more than a space-consuming novelty. Turns out...I could have had some fun and a useful piece of hardware at the same time. Maybe it's time to go bargain-hunting again. For more information about repurposing classic Apple hardware and learning a few JDK-related tricks in the process, visit John's site for the full article, available here. All the best,Mark

  • New SPC2 benchmark- The 7420 KILLS it !!!

    - by user12620172
    This is pretty sweet. The new SPC2 benchmark came out last week, and the 7420 not only came in 2nd of ALL speed scores, but came in #1 for price per MBPS. Check out this table. The 7420 score of 10,704 makes it really fast, but that's not the best part. The price one would have to pay in order to beat it is ridiculous. You can go see for yourself at http://www.storageperformance.org/results/benchmark_results_spc2The only system on the whole page that beats it was over twice the price per MBPS. Very sweet for Oracle. So let's see, the 7420 is the fastest per $. The 7420 is the cheapest per MBPS. The 7420 has incredible, built-in features, management services, analytics, and protocols. It's extremely stable and as a cluster has no single point of failure. It won the Storage Magazine award for best NAS system this year. So how long will it be before it's the number 1 NAS system in the market? What are the biggest hurdles still stopping the widespread adoption of the ZFSSA? From what I see, it's three things: 1. Administrator's comfort level with older legacy systems. 2. Politics 3. Past issues with Oracle Support.   I see all of these issues crop up regularly. Number 1 just takes time and education. Number 3 takes time with our new, better, and growing support team. many of them came from Oracle and there were growing pains when they went from a straight software-model to having to also support hardware. Number 2 is tricky, but it's the job of the sales teams to break through the internal politics and help their clients see the value in oracle hardware systems. Benchmarks like this will help.

  • Most suited technology for browser games?

    - by Tingle
    I was thinking about making a 2D MMO which I would in the long run support on various plattforms like desktop, mac, browser, android and ios. The server will be c++/linux based and the first client would go in the browser. So I have done some research and found that webgl and flash 11 support hardware accelerated rendering, I saw some other things like normal HTML5 painting. So my question is, which technology should I use for such a project? My main goal would be that the users have a hassle free experience using what there hardware can give them with hardware acceleration. And the client should work on the most basic out-of-the-box pc's that any casual pc or mac user has. And another criteria would be that it should be developer friendly. I've messed with webgl abit for example and that would require writing a engine from scratch - which is acceptable but not preferred. Also, in case of non-actionscript, which kind language is most prefered in terms of speed and flexability. I'm not to fond of javascript due to the garbage collector but have learned to work around it. Thank you for you time.

  • What is the value of workflow tools?

    - by user16549
    I'm new to Workflow developement, and I don't think I'm really getting the "big picture". Or perhaps to put it differently, these tools don't currently "click" in my head. So it seems that companies like to create business drawings to describe processes, and at some point someone decided that they could use a state machine like program to actually control processes from a line and boxes like diagram. Ten years later, these tools are huge, extremely complicated (my company is currently playing around with WebSphere, and I've attended some of the training, its a monster, even the so called "minimalist" versions of these workflow tools like Activiti are huge and complicated although not nearly as complicated as the beast that is WebSphere afaict). What is the great benefit in doing it this way? I can kind of understand the simple lines and boxes diagrams being useful, but these things, as far as I can tell, are visual programming languages at this point, complete with conditionals and loops. Programmers here appear to be doing a significant amount of work in the lines and boxes layer, which to me just looks like a really crappy, really basic visual programming language. If you're going to go that far, why not just use some sort of scripting language? Have people thrown the baby out with the bathwater on this? Has the lines and boxes thing been taken to an absurd level, or am I just not understanding the value in all this? I'd really like to see arguments in defense of this by people that have worked with this technology and understand why its useful. I don't see the value in it, but I recognize that I'm new to this as well and may not quite get it yet.

  • What Pattern will solve this - fetching dependent record from database

    - by tunmise fasipe
    I have these classes class Match { int MatchID, int TeamID, //used to reference Team ... other fields } Note: Match actually have 2 teams which means 2 TeamID class Team { int TeamID, string TeamName } In my view I need to display List<Match> showing the TeamName. So I added another field class Match { int MatchID, int TeamID, //used to reference Team ... other fields string TeamName; } I can now do Match m = getMatch(id); m.TeamName = getTeamName(m.TeamId); //get name from database But for a List<Match>, getTeamName(TeamId) will go to the database to fetch TeamName for each TeamID. For a page of 10 Matches per page, that could be (10x2Teams)=20 trip to database. To avoid this, I had the idea of loading everything once, store it in memory and only lookup the TeamName in memory. This made me have a rethink that what if the records are 5000 or more. What pattern is used to solve this and how?

  • The battery indicator in Unity panel not showing up

    - by user61415
    I installed Ubuntu 12.04 with Wubi. Well after being completely dazzled with the amount of free content in the Software Centre, I decided to go deeper and start messing with settings. Well after changing the screen brightness the highest level I noticed that there wasn't an indicator for how much battery was left in my laptop. I looked up online on got 2 suggestions on how to fix: Right click on the Unity panel and add an indicator Set it to show in the power settings menu. Well I did both when I right click at the top menu nothing comes up and setting it to show does nothing either. Then I tried installing something in the Software Centre. I got something but when I activated it it said I had 0% power left even though I was charging and at %100 according the Light in the front of my laptop. So now I'm thinking that it doesn't even recognise my computer as a laptop which is weird because in the display settings it says my screen size is set to laptop. How can I install it? I don't know what version it is other then Ubuntu 12.04 and no matter what the icon does not appear with the

    The premise of the site is that a user pays a small fee to advertise an item that they want to sell. Therefore the user is responsible for adding the "products", not the administrator. The product upload will create a product page for that item. This is a rather common framework that I'm sure you're familiar with. My initial thought was that it would be best suited using Magento - mainly because it needs to accept payments - and the products will grow to form a catalog of categorized products. However - there is no concept of a shopping cart. A buyer does not buy the item online, or go to a checkout. They simply look at the product, and contact the seller if they like it. The buyer and seller then take it from there. For this reason, I then begin to suspect that Magento is perhaps too overkill, or just simply not the right CMS if there is on checkout procedure (other than the uploader making a payment) So then I begin to think Wordpress....Hmmm Feature requirements: User's can add content via a form process User's can be directed to a payment gateway For each product listing - a series of photographs shall be displayed, in thumbnail form Zoom capabilities/rotate on the images would be a welcome feature In short - e-commerce CMS, or something more simple?

  • How do I use an API?

    - by GRardB
    Background I have no idea how to use an API. I know that all APIs are different, but I've been doing research and I don't fully understand the documentation that comes along with them. There's a programming competition at my university in a month and a half that I want to compete in (revolved around APIs) but nobody on my team has ever used one. We're computer science majors, so we have experience programming, but we've just never been exposed to an API. I tried looking at Twitter's documentation, but I'm lost. Would anyone be able to give me some tips on how to get started? Maybe a very easy API with examples, or explaining essential things about common elements of different APIs? I don't need a full-blown tutorial on Stack Overflow; I just need to be pointed in the right direction. Update The programming languages that I'm most fluent in are C (simple text editor usually) and Java (Eclipse). In an attempt to be more specific with my question: I understand that APIs (and yes, external libraries are what I was referring to) are simply sets of functions. Question I guess what I'm trying to ask is how I would go about accessing those functions. Do I need to download specific files and include them in my programs, or do they need to be accessed remotely, etc.?

  • Connecting / disconnecting DisplayPort causes crash

    - by iGadget
    I wanted to file a bug about this using ubuntu-bug xserver-xorg-video-intel, but the system prompted my to try posting here first. So here goes :-) While the situation in Ubuntu 11.10 was still somewhat workable (see UI freezes when disconnecting DisplayPort), in 12.04 (using Unity 3D) it has gotten worse. The weird part is that during the 12.04 beta's, the situation was actually improving! I was able to successfully connect and disconnect a DisplayPort monitor without the system breaking down on me. But now with 12.04 final (with all updates), it's just plain terrible. When I now connect an external monitor using the DisplayPort connector on my HP ProBook 6550b, it only works sometimes. Most times (but not always!) the screen just goes blank and the system seems to crash (not even CTRL+ALT+F1 works anymore). Only a hard shutdown by keeping the power button pressed for several seconds and then a restart gets me out of this. I suspect the chances of the system crashing become higher as the system's uptime increases, especially when there have been one or more suspend-resume cycles (although I have also experienced this bug once from a cold boot). Disconnecting is roughly the same as with 11.10 (see issue mentioned above), with the difference that if I resume from suspend, I no longer have to do a CTRL+ALT+F1, ALT+F7 cycle to get my screen back. So what more can I try? Or should I just go ahead and file the bug anyway?

  • All in a Day's Work: Unblocking Multiple Downloaded Files with a Single Command

    - by Sam Abraham
    Files downloaded using Internet Explorer retain Internet Zone permission level and hence are “Blocked” by default on Windows 7 machines. Honestly, while an added overhead for developers; I really appreciate this feature as it provides a good protection layer for casual web users. My workaround is to simply unblock the downloaded zip file (if download was a zip file) which, in turn, unblocks the files stored within. Today however, I was left with a situation where I had to “Open” and “Copy” the content rather than “Save” a zip file. That of course left me with a few dozen files I have to manually unblock. A few minutes of internet search lead me to the link below which worked like a charm: 1-Download streams.exe from SystInternals - http://technet.microsoft.com/en-us/sysinternals/bb897440.aspx 2-Go to command prompt (cmd.exe) 3-Navigate to where you have streams.exe installed 4-Use command line switches: streams.exe –s –d “<folder path>” This removed the Internet Zone restrictions from all files under “<folder path>” and its subfolders as well.
