  • Best practice for storing HTML coming from text fields to a database?

    - by user1767270
    I have an application that allows users to edit certain parts of text and then email that out. My question is what is the best way to store this in a Microsoft SQL Server database. Right now I have two tables, one holding the HTML data and one holding the plain text data. When the user saves the info, it replaces newlines with br's and puts it in the HTML-conntaining table and then puts the regular text in the other table. This way the text box has the newlines when they go to edit, but the table that contains the HTML data, has the BR's. This seems like a silly way to do things. What would be the best practice? Thanks.

  • Dual Monitor results in 'greyed' windows

    - by paula
    This occurs in Maverick and Natty. Single screen is fine, mirror of single screen is fine. If the mirror box is unchecked and the second monitor is turned on to extend the desktop then all windows are greyed out (like they do when a process has timed out and is unresponsive) and pop up menus are greyed out but icons, panels and background are fine and the windows do operate (just can't see them well enough to use) I have a D620 with intel graphics. This machine did work with dual monitors at some time in the past, however I have been using another machine, a D630 with nvidia and it works fine. Yes, there have been any number of updates. I also upgraded from Maverick to Natty to see if it would go away. No joy. Also, the D620 has a dual boot windows system and the windows xp system works fine with daul monitors There is a forum thread that goes into more detail and there are a number of users experiencing this problem. Thread: greyed out windows Thanks for reading paula_ke

  • New Tabs at End Opens New Tabs at the End of the Chrome Tab Bar

    - by Jason Fitzpatrick
    Chrome: If you’d prefer to have new tabs open at the end of the row instead of next to their parent tab, New Tabs at End is a simple Google Chrome extension that will scoot your tabs where you want them. It’s a minor thing, to be sure, but many users prefer to have tabs open at the end of the row–I know it took me quite awhile as a new Chrome user to get used to the default next-to-parent action. If you’d prefer to have the new tabs open at the end, hit up the link below to install New Tabs at End to tweak your tab bar workflow.

  • "My stuff" vs. "Your stuff" in UI texts

    - by JD Isaacks
    When refering to a users stuff should you use My or Your, for example: My Cart | My Account | My Wishlist Or Your Cart | Your Account | Your Wishlist I found this article that argues for the use of your. It says flikr does this. It also says MySpace and MyYahoo are wrong. I also noticed today that Amazon uses the term Your. However, I have heard they are the masters at testing variations and finding the best one, so what you see on their site might be the best variation, or simply something they are currently testing. I personally like the way my looks better, but thats just my opinion. What do you think? What will hever the better impact on customers? Does it really even matter?

  • Models, controllers, and code reuse

    - by user11715
    I have a blog where users can post comments. When creating a comment, various things happen: creating the comment object, associations, persisting sending notification emails to post's author given his preferences sending notification to moderators given their preferences updating a fulltext database for search ... I could put all this in the controller, but what if I want to reuse this code ? e.g. I would like to provide an API for posting comments. I could also put this in the model, but I wonder if I won't lose flexibility by doing so. And would it be acceptable to do all of this from the model layer ? What would you do ?

  • 301 redirect www to non-www [duplicate]

    - by Claudiu
    This question already has an answer here: Removing non-www support 4 answers I understand that it is better to make a 301 redirect to make sure that all your links are seen the same on Google. Until now I always used erasmus-plus.ro without the www. for my website. Is it ok to make a redirect from www. to non-www. From my search on Google all users spoke about it the other way around. And somewhere I read that redirects are not good for seo. Is 301 an exception?

  • How do I open up firewall while keeping it safe?

    - by d3vid
    Since I've installed Firestarter I have encountered connectivity issues that are all resolved by disabling the firewall. I'd prefer to have the firewall running and allow all the traffic I normally use: Wired network + wireless network, whichever I'm connected to, or both (1) OpenVPN VirtualBox internal network Samba (for accessing shared Windows folders and sharing folders to Windows) (2) BitTorrent And everything else I use that I can't think of :) All the above works without a firewall. I thought Linux was super secure (I update regularly). Do I really need it? (1) I used the Firestarter wizard and selected wlan0 as my primary connection, now whenever I plug in a network cable, I lose all connectivity. Should I just redo the wizard for eth0, or will I then lose wlan0? (2) If it makes a difference I'm sharing a directory that I share between local users using bindfs. See my answer to Good and easy way to share files on local machine

  • Inspiron N7110 Ubuntu 12.04 Poor WiFi Signal

    - by Joseph Risley
    Sorry if this is a repeat, I have been Googling possible answers and have not found one yet. I find my wireless signal is never 100%. Speed is fine, it's the actual signal strength that is the issue. I thought my router was the issue, but the problem was also present at the public library today. I asked the Windows and Mac users around me about their signal strength and they had full signal while mine was medium to low according to WiFiRadar. Is this a Dell problem (Realtek), or an Ubuntu problem I can fix in the terminal?

  • User Productivity Kit - Powerful Packages (Part 2)

    - by [email protected]
    In my first post on packages I described what a package is and how it can be used. I also started explaining some of the considerations that should be taken into account when determining how to arrange your packages. The first is when the files are interrelated and depend on one another such as an HTML file and it's graphics. A second consideration is how the files are used in your outlines. Let's say you're using a dozen Word doc files. You could place them all in a single package or put each Word doc file in a separate package but what's the right thing to do? There are several factors that will influence your decision. To understand the first, let me explain a function of UPK publishing. Take an outline in UPK that has an attachment (concept, frame link, or hyperlink) that points to a file in a package. When you publish this outline, the publishing engine will determine that there is a link to a file in the package and copy the contents of the package to the publishing destination directory. This is done to ensure that any interrelated files are kept together. For the situation where you have an HTML file with links to number of graphics files, this is a good thing. If, however, the package has a dozen unrelated Word doc files and you link to only one of them, all dozen Word documents will be copied to the publishing destination directory.  Whether or not this is a good thing is dependent on two things. First, are all of the files in the package used in the outline that you're publishing? Take an outline that includes links to all of the Word documents in that dozen document package I described earlier. For this situation, you may choose to keep all the files in a single package for convenience. A second consideration is how your organization leverages reuse in UPK. In this context, I'm referring to the link style of reuse such as when you link to the same topic from multiple UPK outlines and changes to the topic appear in both places. Take an example where you have the earlier mentioned dozen Word document package and an outline with a dozen topics in it. Each topic has an attachment pointing to one of the Word documents in the package (frame link, concept, etc.) If you're only publishing this outline, the single package probably works fine but what if you're reusing one of these topics in another outline? As I explained earlier, linking to one file in the package will result in all files in the package being copied to your published output. In this example, linking to one topic in the first outline will result in all dozen Word documents being copied to the published output. This may result in files in the output that you don't want there for business or size reasons. This is a situation in which you should consider placing each of the Word documents in it's own separate package. With each document in it's own package, that link to a single document will result in only that single package and single Word document being copied to the published output. In my last post I had described that packages are documents in the UPK library. When using the multi-user version of the UPK Developer you can leverage standard library capabilities for managing the files in these packages during the development process - capabilities such as check in / check out, history, etc. When structuring your packages take into consideration how the authors are going to be adding, modifying and deleting files from the packages. A single package is a single document in the UPK library. Like any other document in the library, a single user can check out the package and edit it at a time. If you have a large number of files in a single package and these must be modified by many users, you need to consider whether this will cause problems as multiple users compete to update the same package. If the files don't depend on each other consider placing the files in separate packages to reduce contention. I hope you've enjoyed these two posts on how you can leverage the power of packages in your content. In summary, consider the following when structuring your packages: Is the asset a single, standalone file or a set of files that depend on each other? Will all the files always be used together in a single outline or may only some of the files be needed based on how the content is reused across multiple outlines? Will multiple developers need to update the files in a single package or should you break it into multiple packages to reduce contention when checking out the document? We'd like to hear from you on how you're using packages in your content. Please add your comments below! Thank you and I hope these two posts have given you additional insights into how to use packages in your content and structure them for efficient use.

  • Where can I buy freely redistributable (creative commons) game assets?

    - by Erlend
    I'd like to know about any 3D asset shops out there that specialize in game assets and, most importantly, license their assets under an open license like Creative Commons or similarly permissive. We are looking to buy some professional looking assets for use and redistribution with our open source 3D game engine. The problem is that all the commercial 3D assets we've come by are only sold under very restrictive licenses, which won't allow us to include the models in our code repository (since free code hosting repositories require that all your data, including media, is open source or otherwise copyleft) nor in turn redistribute the assets as part of our downloadable SDK. I realize this sounds like a weak business idea, since users could just buy the asset and start sharing it with everyone. But somehow this has worked for hundreds of WordPress theme shops, so I was hoping maybe someone's trying similar things for commercial game assets.

  • Creating a spin from my installation

    - by LinuxPCplus
    Over the last 6 months or so I have tweaked & customized my Ubuntu installation until I have what I feel is a perfect Distro! Now I would like to turn it into a custom Ubuntu spin that can be run either as I live DVD/USB or installed to a users HDD. Is there an "easy" way to do this? I would want to use the standard Ubuntu installer but the distro would have it's own name, so I may need to customize the installer to reflect this.

  • How can videos from Ubuntu drive appear on web page and play in an embedded Flash Player?

    - by nLinked
    I have a shared folder on Ubuntu Server 12.04. Users drop videos in. Ubuntu runs a Cron task to convert them to FLV format and put them into another folder. All I would like is a simple web page that displays all the files in that folder as links, and when you click on the link for the video you want to play, it should play in the same web page inside an embedded Flash/SWF player. Sounds really basic but I'm actually struggling to find a simple solution. Any thoughts appreciated!

  • Java or Python for internet application?

    - by jpartogi
    In choosing a technology for internet applications where the number of users may scale over time, which one should we consider: Java or Python? What are the considerations in choosing one and not the other? If speed and scalability is our main criteria, which one should we use? We have looked around and it seems that there are more websites that use Python [i.e : Quora, digg, reddit, bitbucket and disqus] than Java. Based on that, can we say that Python is more suitable for internet applications where speed and scalability is the main criteria? However we have browsed around and found some comments saying that Java is actually faster than Python. Thank you for your insights.

  • Multithreaded UI desktop application issues

    - by igor
    I am involved into development a rich UI project: desktop windows application. Application uses asynchronous invocations and in its turn it should be ready to process external messages (events). The problem is clear: at first time it was built as a simple prototype and it was not stress tested and all was fine. Then application was grown: the number of calls to server and number of events from server are high and performance is low. What is more users noticed that sometimes performance is extremal low. Asynchronous invocations based on thread pool (BeginInvoke, EndInvoke), external events are going from WCF service (.NET 3.5). My goal is synchronization of all tasks and putting priorities to every executions in desktop application. My question is: is there any practice how to reach my goal: patterns, task priority list, others? What should I do at first, second and next times? Thanks

  • 5 Ways to Determine Mobile Location

    - by David Dorf
    In my previous post, I mentioned the importance of determining the location of a consumer using their mobile phone.  Retailers can track anonymous mobile phones to determine traffic patterns both inside and outside their stores.  And with consumers' permission, retailers can send location-aware offers to mobile phones; for example, a coupon for cereal as you walk down that aisle.  When paying with Square, your location is matched with the transaction.  So there are lots of reasons for retailers to want to know the location of their customers.  But how is it done? I thought I'd dive a little deeper on that topic and consider the approaches to determining location. 1. Tower Triangulation By comparing the relative signal strength from multiple antenna towers, a general location of a phone can be roughly determined to an accuracy of 200-1000 meters.  The more towers involved, the more accurate the location. 2. GPS Using Global Positioning Satellites is more accurate than using cell towers, but it takes longer to find the satellites, it uses more battery, and it won't well indoors.  For geo-fencing applications, like those provided by Placecast and Digby, cell towers are often used to determine if the consumer is nearing a "fence" then switches to GPS to determine the actual crossing of the fence. 3. WiFi Triangulation WiFi triangulation is usually more accurate than using towers just because there are so many more WiFi access points (i.e. radios in routers) around. The position of each WiFi AP needs to be recorded in a database and used in the calculations, which is what Skyhook has been doing since 2008.  Another advantage to this method is that works well indoors, although it usually requires additional WiFi beacons to get the accuracy down to 5-10 meters.  Companies like ZuluTime, Aisle411, and PointInside have been perfecting this approach for retailers like Meijer, Walgreens, and HomeDepot. Keep in mind that a mobile phone doesn't have to connect to the WiFi network in order for it to be located.  The WiFi radio in the phone only needs to be on.  Even when not connected, WiFi radios talk to each other to prepare for a possible connection. 4. Hybrid Approaches Naturally the most accurate approach is to combine the approaches described above.  The more available data points, the greater the accuracy.  Companies like ShopKick like to add in acoustic triangulation using the phone's microphone, and NearBuy can use video analytics to increase accuracy. 5. Magnetic Fields The latest approach, and this one is really new, takes a page from the animal kingdom.  As you've probably learned from guys like Marlin Perkins, some animals use the Earth's magnetic fields to navigate.  By recording magnetic variations within a store, then matching those readings with ones from a consumer's phone, location can be accurately determined.  At least that's the approach IndoorAtlas is taking, and the science seems to bear out.  It works well indoors, and doesn't require retailers to purchase any additional hardware.  Keep an eye on this one.

  • How does landscape calculate free memory?

    - by David Planella
    I'm trying to debug an OOM situation in an Ubuntu 12.04 server, and looking at the Memory graphs in Landscape, I noticed that there wasn't any serious memory usage spike spike. Then I looked at the output of the free command and I wasn't quite sure how both memory usage results relate to each other. Here's landscape's output on the server: $ landscape-sysinfo System load: 0.0 Processes: 93 Usage of /: 5.6% of 19.48GB Users logged in: 1 Memory usage: 26% IP address for eth0: - Swap usage: 2% Then I run the free command and I get: $ free -m total used free shared buffers cached Mem: 486 381 105 0 4 165 -/+ buffers/cache: 212 274 Swap: 255 7 248 I can understand the 2% swap usage, but where does the 26% memory usage come from?

  • How do you limit root partition disk access to allow drive to go into stanby mode?

    - by Casey
    When there are no users on my system, I would like the hard disk to spindown to low-power state. I realize that this might not be 100% achievable for a straight 24 hours, but it seems reasonable that the system could remain idle for a few hours at a time when it is not in use. My system is headless and running a limited number of services. The primary services are: exim4, mythtv-backend, nfs, samba, cups, apt-cacher-ng Assume that drives are already enabled to go into standby mode. Also, its not acceptable to increase the write-back timeout, since my system is not on a UPS.
