• How to make browser offer "remember password"

  - by Alois Mahdal

  What properties login form needs to have to trigger "remember password" for all (or most) browsers? Background: For years I have been using Opera, and the rule has been that almost anything that looks like login form triggers this feature. Now I'm exploring other browsers, and surprisingly find that one of login forms I visit most often, Roundcube login page, does not trigger this feature neither in Chromium nor Firefox (tried various versions and page setups of RC). Since it's on my VPS, I could patch it up and eventually even send that to RC development team, but I have the unnerving feeling that this must have been solved over and over, and it's just me being blind or something. So again: is there any consensus between browser developer as to when this featue should be triggered? Is there a best practice for webmasters to tell the browser "this is the login page"? Or are all browsers doing their own heuristics?

• Java based webservices

  - by java_mouse

  We are working on a big java project and as a second phase in this project, we will have to develop some web services that the clients can call and get or update the data in our database. Though I have been a Java programmer for a while, I have never worked on web services yet. I develop EJBs, data services layer etc but have not worked in web services yet. What are the current standards in developing web services in Java platform? What is the best and recommended way for developing web-services? Any input/link will be appreciated

• [Silverlight] How to choose the webcam resolution

  - by Benjamin Roux

  Hello, Today I’m gonna show you how to choose the webcam resolution when using Silverlight. By default most of them are in 640x480 which can be sometimes insufficient. VideoCaptureDevice source = devices.SelectedItem as VideoCaptureDevice; source.DesiredFormat = new VideoFormat(PixelFormatType.Unknown, 4096, 4096, 30); The magic thing with this line, is that the camera will choose the best resolution available (and not absolutely 4096x4096). You can also get all the supported formats using the SupportedFormats property. Hope this help.

• gnome-control-center can't set display resolution under openbox

  - by Andy

  I'm running Ubuntu 11.10 with Openbox on my laptop. Since I need to plug different external displays into it and Openbox environment doesn't automatically pick them up, I thought the best solution I can come up with is to use gnome-control-center and it's display settings tool from within Openbox. But although this tool does detect monitors correctly, it can't do any change -- clicking Apply button just doesn't seem to do anything. So my questions are: 1) how to get this tool working? 2) how to run "Displays" tool directly from command-line, skipping control center? 3) is there a better way to automatically detect and set resolutions on internal/external monitors under Openbox? Please note I tried arandr too and it doesn't even work for my environment (doesn't detect external display plugging in at all). For what it's worth, my laptop is Lenovo G560, Ubuntu is x64 version with all the updates rolled over. Thanks for your consideration.

• Should I use rel=index or rel=contents in this instance?

  - by Martin Bean

  I’m creating an MMA website. There’s the home page, there’s a fighters section whose index page lists fighters in the organisation, and then each fighter has a profile page. The URL structure is like this: / /fighters/ /fighters/john-doe My question is: on the fighter’s profile page I want to link to the fighters index page (/fighters). In my HTML page, which meta tag would be the most appropriate? <link href="/fighters/" rel="index" /> Or: <link href="/fighters/" rel="contents" /> I’m having trouble distinguishing which would be best, and whether rel="index" would be the index for the whole site or the current page/section I’m viewing?

• Java Alphabetize Algorithm Insertion sort vs Bubble Sort

  - by Chris Okyen

  I am supposed to "Develop a program that alphabetizes three strings. The program should allow the user to enter the three strings, and then display the strings in alphabetical order." It's instructed that I need to use the String library compareTo()/charAt()/toLowerCase() to make all the characters lowercase so the Lexicon comparison is also a alphabetical comparison. Input Pseudo Code: String input[3]; Scanner keyboard = new Scanner(System.in); System.out.println("Enter three strings: "); for(byte i = 0; i < 3; i++) input[i] = keyboard.next() The sorting would be Insertion Sort: 321 2 3 1 2 31 231 1 23 1 2 3 1 23 1 23 123 Bubble Sort 321 231 213 123 Which would be more efficient in this case? The bubble sort seems to be more efficient though they seem to have equal stats for worst best and avg case, but I read the Insertion Sort is quicker for small amounts of data like my case.

• SEO URL structure for tag search on site

  - by Theo G

  I am looking to add tags to each product on my site e.g. brown, x products under £x, second hand x, refurbished x etc. Once you click these tags it will then search for other tags that are similar. I was thinking of using a url structure of www.site.com/tags/this%is%the%tag%name and then simply have a page that shows the results of all the products with that tag. I heard a while back that google generally ignores or downgrades anything with ‘search’ in the url and was wondering if anyone had any experience with this? Also, would you say /tags/ is a pretty valid destination or is it best to break it down and add more levels e.g. /product-type/product%variation Thanks in advance!

• how to select categories for user generated content site?

  - by Frederik Creemers

  On the site I'm building, users can create tutorials. I want the users to be able to create tutorials on as many subjects as possible, but still have some preset categories. What's the best way to select these categories? The reason I don't just let users add keywords, and use these for categorization, is because users gain experience points in a certain subject when their tutorial is liked by someone, and in a similar way the Stack Exchange network does, create communities around these subjects. I will give visiters the possibility to suggest new categories. here are the categories that I'm thinking of at the moment: health gardening cooking technology science & math music visual art

• Is it worth it to switch from home-grown remote command interface to using JMX

  - by Sam Goldberg

  Without knowing too much about JMX, I've always assumed that it would be the best approach for building in remote management to our standalone Java server application. Our server application has some minimal remote control capability, using text commands sent via TCP/IP socket to it. Using the home grown approach, it is fairly to add a new command. (Just create new command text, and the code to handle that in the message receiver). On the other hand, we have hardly implemented any commands, even though there are many things we would like to be able to execute remotely. I am trying to weigh the value of moving to incorporating JMX (learning it, and building the interfaces), versus just sticking with the home-grown approach. Does anyone have any experience or advice regarding changing an existing application to use JMX?

• Digg alternatives for blog and unpopular users? [closed]

  - by Wladimir Ivanov

  all. I'm struggling to build an [B]audience[/B] for [B]electronic blog[/B] . The blog is relatively new and has around 30 pages. The unique visitors I get are approximately [B]120 - daily[/B]. I know about directories, rss, comments and guest blogging, but is there other more effective strategy to build some quality audience? As I see nowadays there aren't enough materials in my country about this. What about digg and reddit? Everytime I post some link there: no traffic comes to me. Can you suggest me other digg/reddit/stumbleupon tactics to get followers or there are similar sites which would tend to give me some serious traffic. Can you suggest sites appropriate for linking to music blog? Best regards.

• How to maximize Java resources for gaming?

  - by Keidax

  I notice that when I play Minecraft, my CPU usage is only around 15 to 20 percent, at most. Is it possible to force my computer to allocate as much RAM, CPU time, etc. to the game, in order to get the best experience possible? Or, is the low CPU usage due to limitations in the JVM or the game code itself? I have OptiFine installed, and I've already tried using renice to change the process priority and -Xmx to allocate more memory to Java. What else can I do?

• SOA, Java EE and data organization

  - by jolasveinn

  At the company I work for, we're currently splitting up our monolith solution into a number of small services (SOA). Many of the services are small, so we'd like to deploy a number of these services on the same application server, JBoss 7.1 in this case. As per the SOA philosophy, the independence of each service and the teams working on them is very important. What would be the best way to organize the data? Use one schema per service Would you use one datasource per schema in the application server? Or use one datasource, prefixing all DB object names with the schema name in some transparent manner? Use a shared schema, but evading any naming collisions by requiring each service to use a distinct prefix for all DB objects Other options? Am I maybe thinking this completely wrong here? :)

• Packages are not available under 13.04?

  - by Sven

  I have a small problem with installing packages under Ubuntu 13.04. Yesterday I wanted to install "pdfshuffler" (https://apps.ubuntu.com/cat/applications/raring/pdfshuffler/). If I go to the Ubuntu Software Center and look for "pdfshuffler" there is one item in the list (the package I want to install). When I click once on this item, the install button does not appear. If I then on furter information a error message appears telling me that there is no package called pdfshuffler in my package sources. I tried to install other packages like Eclipse or Supertux but nothing works. Why can't Ubuntu find these packages? Best regards, Sven...

• Already have Merchant Account, what info will my Gateway need?

  - by Anonymous Coward

  I have a client who already has a merchant account for their physical store. What specific information about the merchant account will my client need to get from his bank to link it up to an online payment gateway that we will be using for the store? -----edits below -"my merchant account" changed to "the merchant account" -It is noted that my client will need to get a "high-risk" merchant account separate from his existing physical stores merchant account. -Though the question is essentially answered, for clarification: We plan to minimize our PCI compliance needs by utilizing something like Braintree's Transparent Redirect or the CRESecure iForm. So the gateway we would need to give the merchant account info to would be either of those two. Though, the CRESecure method would have yet one more step added into the mix since they would forward data to another payment provider. It is now assumed that the best place to field this question is to the support team at Braintree or CRESecure.

• Should I get an SGC enabled SSL certificate?

  - by Simon

  I'm in the market for a new SSL certificate and am wondering if I should get an SGC enabled certificate or not? In the past I have just used cheap SSL certificates but since this is for a new company website I want to make sure I have the best but I am unsure whether it is worth paying the extra. The documentation states that it just enables older browsers to use 128 bit encryption when they would normally only be able to use 40 or 56 bit encryption. Would you pay the extra for older browsers which are likely to be extremely rare?

• Rebuild package from upstream source?

  - by Andrew

  I'm trying to rebuild a package (specifically grub2) to overcome some bugs that have been fixed upstream but not fixed in Ubuntu, and have the package integrate into Ubuntu properly. The package is hosted in bzr both on Launchpad and GNU Savannah. How can convert a "raw" upstream source package into an "Ubuntu" version and recompile/repackage it? I've worked out that I can get the latest Ubuntu version of the package source with apt-get source, but there are significant differences to the upstream version. What is the best course of action here?

• Disable suspend / hibernate via the policykit

  - by redonath

  I am trying to run Lubuntu 12.04, but if the computer suspends I am unable to bootup again. Instead I see the bios post, the hard disk light flickers once and I have to install again (I have tried to re-install grub2). I am new to Linux and what I found that best answered my question was posted by James Henstridge. The instructions say to create disable-shutdown.pkla in etc/polkit-1/50-local.d/ but this directory does not exist, so do I create a folder titled 50-local.d in poolkit-1 or do I have to place this file elsewhere?

And please clarify me Websites are stored in servers. From my desktop, i want to broadcast some video, then i need to connect to webserver(to upstream the video).

• For what types of applications is Python a bad choice?

  - by Casey Patton

  I just started learning Python, and I'd like to get some more context on the language. I realize that Python is a slow language relative to C or C++, etc. Thus, Python is probably not the best choice for applications that need to run quickly. Outside of this, it seems like Python is a great general purpose language that is easy to read and write. The available libraries give it a huge amount of functionality. Outside of performance critical applications, where is it a bad choice to use Python (and why)?

• How to handle estimates for programmers joining the team?

  - by Jordan

  Iteration has already started, new programmer joins the team, task X has already been estimated to be 30 hours by a different developer. What is the best practice in this situation? new developer runs with the given estimate (the idea being that any discrepancy will be corrected for when velocity is calculated?) new developer re-estimates task? (if so, what if it's significantly higher and no longer fits in the iteration?) throw our hands up and go back to waterfall? something else entirely?

• How can I make my main character move in a parabolic arc when jumping?

  - by user1276078

  I'm entering Android game development, and I already have a computer version of a game I want to publish. The thing is, I want to make this as good as it can be. With that said, I need a physics engine, really to only do one thing: make a parabolic movement of my main character as he's jumping in the air. Currently, my computer version simply makes the guy move up at a 45 degree angle, and as soon as it hits the ceiling, down at a 45 degree angle. I need a physics engine/library that would accomplish that, it has to be in java since that's my best language, it has to be 2D, and it has to be able to work on Android. Which physics engine/library could accomplish all of that?
