  • Sesame Data Browser: filtering, sorting, selecting and linking

    - by Fabrice Marguerie
    I have deferred the post about how Sesame is built in favor of publishing a new update.This new release offers major features such as the ability to quickly filter and sort data, select columns, and create hyperlinks to OData. Filtering, sorting, selecting In order to filter data, you just have to use the filter row, which becomes available when you click on the funnel button: You can then type some text and select an operator: The data grid will be refreshed immediately after you apply a filter. It works in the same way for sorting. Clicking on a column will immediately update the query and refresh the grid.Note that multi-column sorting is possible by using SHIFT-click: Viewing data is not enough. You can also view and copy the query string that returns that data: One more thing you can to shape data is to select which columns are displayed. Simply use the Column Chooser and you'll be done: Again, this will update the data and query string in real time: Linking to Sesame, linking to OData The other main feature of this release is the ability to create hyperlinks to Sesame. That's right, you can ask Sesame to give you a link you can display on a webpage, send in an email, or type in a chat session. You can get a link to a connection: or to a query: You'll note that you can also decide to embed Sesame in a webpage... Here are some sample links created via Sesame: Netflix movies with high ratings, sorted by release year Netflix horror movies from the 21st century Northwind discontinued products with remaining stock Netflix empty connection I'll give more examples in a post to follow. There are many more minor improvements in this release, but I'll let you find out about them by yourself :-)Please try Sesame Data Browser now and let me know what you think! PS: if you use Sesame from the desktop, please use the "Remove this application" command in the context menu of the destkop app and then "Install on desktop" again in your web browser. I'll activate automatic updates with the next release.

  • Am I wrong to disagree with A Gentle Introduction to symfony's template best practices?

    - by AndrewKS
    I am currently learning symfony and going through the book A Gentle Introduction to symfony and came across this section in "Chapter 4: The Basics of Page Creation" on creating templates (or views): "If you need to execute some PHP code in the template, you should avoid using the usual PHP syntax, as shown in Listing 4-4. Instead, write your templates using the PHP alternative syntax, as shown in Listing 4-5, to keep the code understandable for non-PHP programmers." Listing 4-4 - The Usual PHP Syntax, Good for Actions, But Bad for Templates <p>Hello, world!</p> <?php if ($test) { echo "<p>".time()."</p>"; } ?> (The ironic thing about this is that echo statement would look even better if time was variable declared in the controller, because then you could just embed the variable in the string instead of concatenating) Listing 4-5 - The Alternative PHP Syntax, Good for Templates <p>Hello, world!</p> <?php if ($test): ?> <p><?php echo time(); ?> </p><?php endif; ?> I fail to see how listing 4-5 makes the code "understandable for non-PHP programmers", and its readability is shaky at best. 4-4 looks much more readable to me. Are there any programmers who are using symfony that write their templates like those in 4-4 rather than 4-5? Are there reasons I should use one over the other? There is the very slim chance that somewhere down the road someone less technical could be editing it the template, but how does 4-5 actually make it more understandable to them?

  • How to install Ubiquity into a Live CD installation image?

    - by Patrick L
    I am trying a create a small Ubuntu installation ISO image. I am using a tool called Ubuntu-Builder. To make the final ISO as small as possible, I have decided to use Ubuntu Mini Remix. It is a small Live CD without GUI. It does not come with any installer software like Ubiquity. I want to embed an installer software into the ISO image so that user can install it into harddisk. In Ubuntu-Builder, I have tried the following: Install LXDE Desktop, then install Ubiquity. But the final ISO boots into command line. Install OpenBox Desktop, then install Ubiquity. But the final ISO boots into command line. Do not install DE, directly install Ubiquity. But the final ISO still boots into command line. After booting up from ISO, I have checked the software in the OS. It seems that Ubiquity has been installed. But it didn't show up when I boot the ISO image. Anyone knows how to install Ubiquity into a Live CD ISO image? Anyone knows any text mode installer which can replace Ubiquity?

  • Apache2 + Php + Pthreads HowTos

    - by Drug
    04 LTS 64 bit. What I would really love to do is sudo apt-get install libapache2-mod-php5 but compile PHP with --enable-maintainer-zts so I could later install pthreads with pecl install pthreads. Sadly I understand that it is not possible. I know that the easiest way is to recompile PHP together with apache support and zts. However I really like the way the standard Ubuntu PHP package is configured and I am used to the path`s for CLI php.ini config, Apache php.ini config and other paths for modules and files that this Ubuntu package defines. So i just want to change the package source a little bit and install it. # Get the stuff necessary to build the package sudo apt-get build-dep php5-common # Get the package source sudo apt-get source php5-common At this point I am getting sources not for the php5-common package but the whole php5 package. If I would sudo make && make install at this point, would it mean that I am installing a lot of unnecessary stuff? # Add configuration options ./configure --enable-maintainer-zts Does this mean that I am appending a configuration option? Or am I generating a whole new config? Alternative at this point Is there a way of getting the config options that this package defines, so that I can grab a php source from php.net and compile it with $ ./configure --prefix=package_prefix \ // Option 1 from package --enable-embed \ // Option 2 from package --with-regex=php \ // Option 3 from package Continuing the main idea ... Solution 1 # Compile (Not compiling) sudo make && make install Will I be building PHP with EVERYTHING at this point? If I compile like this, I will not be able to remove the mess I made using sudo apt-get purge php5? Solution 2 # ReCompile the package dpkg-buildpackage -rfakeroot -uc -b This does not compile also. Please correct my steps, so I can install everything correctly.

  • 2-D Codes in Retail

    - by David Dorf
    The UPC you find on packaging is a one-dimensional barcode that's been in use, in one form or another, since the 1970s. While its a good symbology to encode numbers like a product identifier, its not really big enough to hold much more. It also requires a barcode scanner (like those connected to the POS), although iPhone apps like RedLaser have proved a mobile camera can be made to work in many situations. The next generation barcodes are two-dimensional and therefore capable of holding much more information as well as being more conducive to cameras. The most popular format is the QR Code, widely used in Japan because almost every mobile phone has a built-in reader. A typical use for QR Codes is to embed a URL so that that a mobile phone can quickly navigate to the specified web page. QR Codes can be found on posters, billboards, catalogs, and circulars. Speaking of which, Best Buy recently put a QR code in their circular as shown below. If fact, they even updated their iPhone application to include a QR Code reader. I was able to scan the barcode above right from the screen with my iPhone without issues, even though its fairly small in this image. Clearly they are planning to incorporate more QR Codes in their stores and advertising. If you haven't seen QR Codes before, you're not looking hard enough. They are around and will continue to spread.

  • Announcing Oracle Environmental Accounting and Reporting

    - by Theresa Hickman
    Oracle just launched a new product called Oracle Environmental Accounting and Reporting designed to help company’s track and report their greenhouse emissions at the operational level.  Companies around the world are facing increasing pressure to improve their energy efficiency and reduce waste in their operations. Also, new worldwide greenhouse gas legislation is putting added pressure on companies to report the impact of their emissions and energy usage on the environment. Today, companies undergo extensive and expensive data audits to maintain a ledger of up-to-date emissions factors that compare figures on an annual basis. Existing “ad hoc” approaches utilizing manual or niche solutions have a high operational cost and weak data security and audit-ability. The ideal solution is to embed environmental usage within the mainstream business operations, such as recording energy usage at the time of invoice entry, and then report on those results. This is precisely what Oracle Environmental Accounting and Reporting is designed to do. You can now capture environmental data either electronically or manually; convert that to greenhouse gas emissions; comply with mandatory and voluntary greenhouse gas reporting schemes; and identify opportunities for CO2 emissions and cost reductions.   Oracle recently acquired the intellectual property for this solution which works with both Oracle E-Business Suite Release 12 and JD Edwards EnterpriseOne Release 9.0. For more information, visit Oracle Environmental Accounting and Reporting.

  • Double vs Single Quotes in Chrome

    - by Rodrigo
    So when you want to embed google docs on a site you are given this chunk of code: <iframe width='500' height='300' frameborder='0' src='https://docs.google.com/spreadsheet/pub?hl=en_US&hl=en_US&key=0AiV6Vq32hBZIdHZRN3EwWERLZHVUT25ST01LTGxubWc&output=html&widget=true'></iframe> This works fine on my site. If you edit the page, we run the new content through some filters to escape out stuff and make sure it is valid html. After the process, the link above gets converted to this: <iframe frameborder="0" height="300" src="https://docs.google.com/spreadsheet/pub?hl=en_US&amp;hl=en_US&amp;key=0AiV6Vq32hBZIdHZRN3EwWERLZHVUT25ST01LTGxubWc&amp;output=html&amp;widget=true" width="500"></iframe> This will work on every browser except for chrome. Chrome thinks I am running JS in the src. I narrowed it down to a combination of double quotes and escaped '&' symbols. If i revert one of those back to the original state, the iframe works. I work in ruby where ' and " have different behaviors. Is Chrome doing the same thing? Is there a way to turn that off?

  • Matching the superclass's constructor's parameter list, is treating a null default value as a non-null value within a constructor a violation of LSP?

    - by Panzercrisis
    I kind of ran into this when messing around with FlashPunk, and I'm going to use it as an example. Essentially the main sprite class is pretty much class Entity. Entity's constructor has four parameters, each with a default value. One of them is graphic, whose default value is null. Entity is designed to be inherited from, with many such subclasses providing their own graphic within their own internal workings. Normally these subclasses would not have graphic in their constructor's parameter lists, but would simply pick something internally and go with it. However I was looking into possibly still adhering to the Liskov Substitution Principal. Which led me to the following example: package com.blank.graphics { import net.flashpunk.*; import net.flashpunk.graphics.Image; public class SpaceGraphic extends Entity { [Embed(source = "../../../../../../assets/spaces/blank.png")] private const BLANK_SPACE:Class; public function SpaceGraphic(x:Number = 0, y:Number = 0, graphic:Graphic = null, mask:Mask = null) { super(x, y, graphic, mask); if (!graphic) { this.graphic = new Image(BLANK_SPACE); } } } } Alright, so now there's a parameter list in the constructor that perfectly matches the one in the super class's constructor. But if the default value for graphic is used, it'll exhibit two different behaviors, depending on whether you're using the subclass or the superclass. In the superclass, there won't be a graphic, but in the subclass, it'll choose the default graphic. Is this a violation of the Liskov Substitution Principal? Does the fact that subclasses are almost intended to use different parameter lists have any bearing on this? Would minimizing the parameter list violate it in a case like this? Thanks.

  • Chainloading GRUB2 from BURG

    - by WindowsEscapist
    I have an old PC with Puppy Linux in addition to Ubuntu and Windows XP. THis creates a LOT of menu entries (all of which I would like to keep): Ubuntu 10.04 Ubuntu Recovery Mode Memtest x86 Memtest Serial Windows XP Pro Precise Puppy Linux Precise Puppy TORAM Puppy 4.3.1 Puppy 4.3.1 TORAM Plop Boot Manager (for booting to USB, PC doesn't have BIOS option). Now, in my fancy shiny laptop I've gotten really attached to BURG, and would like a setup where I have a Windows icon, an Ubuntu icon, and an arrow that chainloads GRUB2 so that I can boot from USB or run Puppy if need be (all these entries will obviously not fit into the BURG theme I use, Lightness). The problem is, GRUB2 can't install the the beginning of a partition like it used to be able to (I am reluctant to specify andything with --force at the end), at least, without warning that warn: This is a BAD idea!. So I'm kind of at a loss here. I can't see how the folding option would work, because all of those other options would have the same icon once I unfolded (Lightness is non-text-based). If I do embed GRUB using grub-install /dev/sdax --force, how do I chainload it with BURG? Is there another way?

  • Language Niches and Niche Libraries

    - by Roman A. Taycher
    "Everyone Knows" ... ... that c is widely used for low level programs in large part because operating system/device apis are usually in c. ... that Java is widely used for enterprise applications in large part because of enterprise libraries and ide support. ... that ruby is widely used for webapps thanks in large part because of rails and its library ecosytem But lets go into to details what are the specific niches and subniches. Especially with respect to libraries. Where might you embed lua for application scripting versus python. Where would you use Java vs C#. Which languages do different scientists use? Also which languages have libraries for these subniches? Things like bioperl/scipy/Incanter. Please no flamewars about how nice each language or environment is. This is where they used. Also no complaints about marketing/PHBs. (Manually migrated) I asked this question again after it was closed on stackoverflow.com

  • Where to place the R code for R+Sweave+LaTeX workflow

    - by claytontstanley
    I spent the last week learning 3 new tools: R, Sweave, and LaTeX. One question that came to my mind though when working through my first project: Where do I place the majority of the R code? The tutorials that I read online placed the majority of the R code in the LaTeX .Rnw file. However, I find having a bunch of R calculations in the LaTeX file distracting. What I do find extremely helpful (of course) is to call out to R code in the LaTeX file and embed the result. So the workflow I've been using is to place 99% of my R code in my .R file. I run that file first, save a bunch of calculations as objects, and output the .Rout file once finished (to save the work). Then when running Sweave, I load up that .Rout file, so that I have the majority of my calculations already completed and in the Sweave R session. Then my LaTeX callouts to R are quite simple: Just give me the XTable stored in 'res.table', or give me the result of an already-computed calculation stored in the variable 'res'. So I push towards the minimal amount of R code in the LaTex file possible, to achieve the desired result (embedding stats results in the LaTeX writeup). Does anyone have any experience with this approach? I'm just worried I might run into trouble further down the line, when I start really trying to load up and leverage this workflow.

  • An experiment: unlimited free trial

    - by Alex.Davies
    The .NET Demon team have just implemented an experiment that is quite a break from Red Gate's normal business model. Instead of the tool expiring after the trial period, it now continues to work, but with a new message that appears after the tool has saved you a certain amount of time. The rationale is that a user that stops using .NET Demon because the trial expired isn't doing anyone any good. We'd much rather people continue using it forever, as long as everyone that finds it useful and can afford it still pays for it. Hopefully the message appearing is annoying enough to achieve that, but not for people to uninstall it. It's true that many companies have tried it before with mixed results, but we have a secret weapon. The perfect nag message? The neat thing for .NET Demon is that we can easily measure exactly how much time .NET Demon has saved you, in terms of unnecessary project builds that Visual Studio would have done. When you press F5, the message shows you the time saved, and then makes you wait a shorter time before starting your application. Confronted with the truth about how amazing .NET Demon is, who can do anything but buy it? The real secret though, is that while you wait, .NET Demon gives you entertainment, in the form of a picture of a cute kitten. I've only had time to embed one kitten so far, but the eventual aim is for a random different kitten to appear each time. The psychological health benefits of a dose of kittens in the daily life of the developer are obvious. My only concern is that people will complain after paying for .NET Demon that the kittens are gone.

  • Is creating a separate pool for each individual image created from a png appropriate?

    - by Panzercrisis
    I'm still possibly a little green about object-pooling, and I want to make sure something like this is a sound design pattern before really embarking upon it. Take the following code (which uses the Starling framework in ActionScript 3): [Embed(source = "/../assets/images/game/misc/red_door.png")] private const RED_DOOR:Class; private const RED_DOOR_TEXTURE:Texture = Texture.fromBitmap(new RED_DOOR()); private const m_vRedDoorPool:Vector.<Image> = new Vector.<Image>(50, true); . . . public function produceRedDoor():Image { // get a Red Door image } public function retireRedDoor(pImage:Image):void { // retire a Red Door Image } Except that there are four colors: red, green, blue, and yellow. So now we have a separate pool for each color, a separate produce function for each color, and a separate retire function for each color. Additionally there are several items in the game that follow this 4-color pattern, so for each of them, we have four pools, four produce functions, and four retire functions. There are more colors involved in the images themselves than just their predominant one, so trying to throw all the doors, for instance, in a single pool, and then changing their color properties around isn't going to work. Also the nonexistence of the static keyword is due to its slowness in AS3. Is this the right way to do things?

  • How to SEO Optimize Javascript Image Loader?

    - by skibulk
    I am building an image-centric catalog website. It catalogs collectible gaming cards numbering 100,000+ pages. Competitor sites recieve millions of hits each month, so with the possibility of excessive traffic, I need to moderate image bandwidth while also optimizing for image SEO. I'm looking for some tips on doing so. Each page on the site features one card with appropriate tags and descriptions. There are however four images for each card - one on matte cardstock, one on foil cardstock, one digital, and one digital foil. In a world with unlimited bandwidth and no-wait page loads, I'd simply embed all four images on the main product page with titles, alt tags, and captions to rank them according to their version keyword. In reality a javascript gallery image loader seems appropriate. Here is a simplified example of my current code. Would this affect SEO in any way? Should I be doing anything differently? Note that I don't want to create a page for each image as I'd have to duplicate the card tags and descriptions on each one, diluting PR for the main page. Thanks for any insight! <script type="text/javascript"> document.write(' <img src="thumbnail1.jpg" data-src="version1.jpg"> <img src="thumbnail2.jpg" data-src="version2.jpg"> <img src="thumbnail3.jpg" data-src="version3.jpg"> <img src="thumbnail4.jpg" data-src="version4.jpg"> '); </script> <noscript> <img src="version1.jpg"> <img src="version2.jpg"> <img src="version3.jpg"> <img src="version4.jpg"> </noscript>

  • Is creating a separate pool for each individual png image in the same class appropriate?

    - by Panzercrisis
    I'm still possibly a little green about object-pooling, and I want to make sure something like this is a sound design pattern before really embarking upon it. Take the following code (which uses the Starling framework in ActionScript 3): [Embed(source = "/../assets/images/game/misc/red_door.png")] private const RED_DOOR:Class; private const RED_DOOR_TEXTURE:Texture = Texture.fromBitmap(new RED_DOOR()); private const m_vRedDoorPool:Vector.<Image> = new Vector.<Image>(50, true); . . . public function produceRedDoor():Image { // get a Red Door image } public function retireRedDoor(pImage:Image):void { // retire a Red Door Image } Except that there are four colors: red, green, blue, and yellow. So now we have a separate pool for each color, a separate produce function for each color, and a separate retire function for each color. Additionally there are several items in the game that follow this 4-color pattern, so for each of them, we have four pools, four produce functions, and four retire functions. There are more colors involved in the images themselves than just their predominant one, so trying to throw all the doors, for instance, in a single pool, and then changing their color properties around isn't going to work. Also the nonexistence of the static keyword is due to its slowness in AS3. Is this the right way to do things?

  • Multiplayer online game engine/pipeline

    - by Slav
    I am implementing online multiplayer game where client must be written in AS3 (Flash) to embed game into browser and server in C++ (abstract part of which is already written and used with other games). Networking models may differ from each other, but currently I'm looking toward game's logic run on both client and server parts but they're written on different languages while it's not the main problem. My previous game (pretty big one - was implemented with efforts of ~5 programmers in 1.5 years) was mainly "written" within electronic tables as structured objects with implemented inheritance: was written standalone tool which generated AS3 and C++ (languages of platforms to which the game was published) using specified electronic tables file (.xls or .ods). That file contained ~50 tables with ~50 rows and ~50 columns each and was mainly written by game designers which do not know any programming languages. But that game was single-player. Having declared problem with my currently implementing MMO, I'm looking toward some vast pipeline, where will be resolved such problems like: game objects descriptions (which starships exist within game, how much HP they have, how fast move, what damage deal...) actions descriptions (what players or NPCs can do: attack each other, collect resources, build structures, move, teleport, cast spells) - actions are transmitted through server between clients influences (what happens when specified action applied on specified object, e.i "Ship A attacked Ship B: field "HP" of Ship B reduced by amount of field "damage" of Ship A" Influences can be much more difficult, yes, e.i. "damage is twice it's size when Ship has =5 allies around him in a 200 units range during night" and so on. If to be able to write such logic within some "design document" it will be easily possible to: let designers to do their job without programmer's intervention or any bug-prone programming validate described logic transfer (transform, convert) to any programming language where it will be executed Did somebody worked on something like that? Is there some tools/engines/pipelines which concernes with it? How to handle all of this problems simultaneously in a best way or do I properly imagine my tasks and problems to myself?

  • Google analytics set up with wrong domain

    - by Tom
    I have recently embedded Google Analytics into a site using the default embed code. <script> (function (i, s, o, g, r, a, m) { i['GoogleAnalyticsObject'] = r; i[r] = i[r] || function () { (i[r].q = i[r].q || []).push(arguments) }, i[r].l = 1 * new Date(); a = s.createElement(o), m = s.getElementsByTagName(o)[0]; a.async = 1; a.src = g; m.parentNode.insertBefore(a, m) })(window, document, 'script', '//www.google-analytics.com/analytics.js', 'ga'); ga('create', 'UA-XXXXXXXX-1', 'MYDOMAIN.COM'); ga('send', 'pageview'); </script> However I had MYDOMAIN.COM set to an incorrect domain. The views for the site seem very low, however, I can see myself there as a visitor in the real time scanner. What effect would setting the domain incorrectly have had? How does Google use this parameter?

  • An experiment: unlimited free trial

    - by Alex.Davies
    The .NET Demon team have just implemented an experiment that is quite a break from Red Gate's normal business model. Instead of the tool expiring after the trial period, it now continues to work, but with a new message that appears after the tool has saved you a certain amount of time. The rationale is that a user that stops using .NET Demon because the trial expired isn't doing anyone any good. We'd much rather people continue using it forever, as long as everyone that finds it useful and can afford it still pays for it. Hopefully the message appearing is annoying enough to achieve that, but not for people to uninstall it. It's true that many companies have tried it before with mixed results, but we have a secret weapon. The perfect nag message? The neat thing for .NET Demon is that we can easily measure exactly how much time .NET Demon has saved you, in terms of unnecessary project builds that Visual Studio would have done. When you press F5, the message shows you the time saved, and then makes you wait a shorter time before starting your application. Confronted with the truth about how amazing .NET Demon is, who can do anything but buy it? The real secret though, is that while you wait, .NET Demon gives you entertainment, in the form of a picture of a cute kitten. I've only had time to embed one kitten so far, but the eventual aim is for a random different kitten to appear each time. The psychological health benefits of a dose of kittens in the daily life of the developer are obvious. My only concern is that people will complain after paying for .NET Demon that the kittens are gone.

  • 3 column layout with css display table, with first row having multiple rows?

    - by Damainman
    I am working on a new website which: Has 3 columns - Each Column being a cell First column has 3 rows (Logo, Nav, icons) - Has a Div with display: table which wraps arround 3 divs with display:table-row. Other two columns only have 1 row. With the middle column being the content area. However since this is my first time using display:table, I am running into some things that aren't so clear to me. I was trying to avoid floating divs. If I need multiple rows with one cell in each row per column, do I embed each cell in a row or just create each row and not declare cells. I understand that browsers automatically create the missing elements but I want to make sure I do this properly to avoid any side effects that might occur due to the browser automatically creating the missing elements. Edit: I think my brain is just over worked, I guess I can accomplish this by just using 3 divs in the first column instead of using a nested table div with the rows. This just popped into my head.

  • Spring Cleaning

    - by Tim Dexter
    I recently got a shiny new laptop; moving my shiz from old to new, was not the nightmare it used to be. I have gotten into the habit of using a second hard drive in the media bay where the CDROM normally sits. That drive contains my life's work with BIP. I can pull it out and plug it into another machine very easily. I have been sorting through some old directories and files, archiving some, sharing others with colleagues. For instance, a little dated but if you were looking for a list of Publisher reports available in EBS R12.1, here it is. Im trying to track down a more recent R12 instance and will re-post the document. I also found another gem; its a little out there in terms of usefulness but Im sharing it none the less. You can embed, locally or remotely reference SVG graphics (in XML format) and bring the images into the BIP outputs. Template and sample data here. A nice set of templates showing page number control and page suppression - they will need some explanation, so I'll save them for another post. The list goes on but I'll save them for later. Back to the clean up!
