• Looking for an ultra portable laptop for Ubuntu

  - by prule

  Hi, I'm in the market for a new laptop, and portability is important since I really only use it when I'm travelling to and from work - primarily for programming. I've been searching high and low for something like this: less than 2kg hopefully Intel i5 (but negotiable) NO dvd drive - just don't need it 4G ram either 7200rpm disk or SSD (ssd preferable) 13 inch screen not too pricey (MacBook Air is about $1700 AUD) available in Australia The Dell Inspiron 13z and Lenovo Edge 13 look close, but I've not found anything that says I'm not going to have a fight with compatibility. The MacBook Air 13 looks like the PERFECT hardware, but I'm afraid it will just be easier to run MacOS than Ubuntu. I want to stay with Ubuntu, but the MacBook Air is only $1700 so I'm in danger of becoming another apple fanboi if I can't find anything competitive. Going through all the sites looking for stuff has been a huge waste of time System 76 doesn't deliver to Australia http://www.linux-laptop.net/ and http://www.linlap.com/ are hard work and not confidence inspiring http://www.vgcomputing.com.au/nsintro.html is hard work again, searching for every laptop they say has excellent compatibility on the web to find out what spec it is http://zareason.com/shop/Strata-Pro-13.html (at $1345 USD) looks interesting, but I've got no idea how much I'll get stung by customs importing Dell Inspiron 13z with i5, 4G, 320 7200rpm disk, ATI Mobility Radeon HD5430 - 1GB, Dell Wireless 1501 802.11b/g/n @ $1200 AUD seems like the only competitor but is it compatible? (Dell support offer no opinion - as far as they are concerned they only have 2 models that are certified for ubuntu) Am I worrying too much about the compatibility? Should I just go with Dell? Or switch to MacOS? (It would be good to have a searchable database that had the full machine specs, and compatibility - I'm thinking about building something... but I don't have much time right now...) Thanks. UPDATE I went with a MacBook Air. The price/weight/power was just right. Everything else was either too pricy (i5) or too heavy, or underpowered (SU7300 1.3GHz). Its a pity, because I didn't really want to leave Ubuntu. I'll still run it on my media center and spare (heavy) laptop.

• Should a URL match the page's title?

  - by Yottatron

  Should the URL of a page match its title? For example: Http://example.com/about-cats.html <title>About Cats</title> Furthermore, if that title were to be changed by the page's author, should the URL change to match and the old URL be redirected (301) to the new URL? Edit Also, if the pages author were to decide to revert his changes after several days, would it be right to remove the redirect and set up an new redirect from the amended URL back to the old URL?

• How come Indiegogo links shared on G+ link to their page instead of displaying URL?

  - by Ivan Vucica

  If an Indiegogo link, such as this one, gets shared on G+, their G+ page is displayed in the post in the place where commonly the URL would be displayed. I've tried looking analyzing the HTML, but came up empty handed: there's Twitter cards metadata, there's OpenGraph, there is a G+ button -- but I found nothing that links to Indiegogo's page, not even rel="publisher". So, how does Indiegogo achieve this?

• CSS alignment differs per page, cant find reason [migrated]

  - by Floran

  I list products on my homepage and on a company details page. I use the exact same HTML, but for some reason the product appears different: The productname is "Artikel 1". Here the product is displayed correctly: http://www.zorgbeurs.nl/ Notice how the green price area is right below the product. But here: http://www.zorgbeurs.nl/bedrijven/76/mymedical the green price area is all the way at the bottom of the page. Why?

• Ubuntu 11.10 crashes all browsers often

  I have been using ubuntu 11.10 for 1 year,today it made me surprised. When I open google chrome it just closes itself.

• What meta tag or microdata should I use for a dictionary web application?

  - by vonPetrushev

  I have a web application that serves as a dictionary, and it ranks good at google when searching for a rare word in my language (the dictionary's target language). I want the result to appear in the define: some-word, as well as in the search results when someone uses the filter tool Dictionary. Should I add some special meta-tag in the head of the html? How about microdata? Does google have a special webmaster tool for registering dictionaries like: wordnetweb.princeton.edu or en.wiktionary.org ?

• C/C++ Best indentation length?

  - by Tim

  I was reading a Vim tutorial ( http://www.oualline.com/vim-cook.html#drawing ), and came across this: This is very useful if you use a 4 space indentation for your C or C++ programs. (Studies at Rice University have shown this to be the best indentation size.) Is there any truth in these studies? Note-- i didn't mean for a flame war in indentation -- just whether anyone else has come across tis study before? EDIT: @MaR I made a poll http://poll.fm/3d5kg

• Styling Windows Phone Silverlight Applications

  - by Tim Murphy

  If you have not developed with styles in Silverlight/XAML then it can be challenging and resources can be sparse depending on how deep you get.  One thing that you need to understand is what level you can apply styles and how much they can cascade.  What I am finding is that this doesn’t go to the level that we are used to in HTML and CSS. While styles can be defined at a page level if you want to share styles throughout your application they should be defined in the App.xaml file.  This is of course analogous to placing a style in your HTML file versus an external CSS file.  This is the type of style I will concentrate on in this post. The first thing to look it how styles associate to elements.  TargetType defines the object type that your style will apply to.  In the example below the style is targeting the TextBlock object type. <Style x:Key="TextBlockSmallGray" TargetType="TextBlock"> Next we use a Setter which allows you to apply values for specific attributes of the target object type.  The setters can be a simple value or complex.  The first example here is simply applying a color to the background property of the target. <Setter Property="Background" Value="White"/> The second setter example here is for the same property, but we are applying a the definition of a LinearGradientBrush. <Setter Property="Background"> <Setter.Value> <LinearGradientBrush> <GradientStop Offset="0" Color="Black"/> <GradientStop Offset="1" Color="White"/> </LinearGradientBrush> </Setter.Value> </Setter> The last thing I want to cover here is that you can leverage the system styles and then override or extend them.  The BasedOn attribute of the Style tag allows this sort of inheritance.  In the example below I am going to start with the PhoneTextTitleStyle and then override properties as needed. <Style x:Key="TextBlockTitle" BasedOn="{StaticResource PhoneTextTitle1Style}" TargetType="TextBlock"> So now that we have our styles defined applying it is fairly straight forward.  Add the style name as a static resource to the style property of the element in your page and off you go. <Grid x:Name="LayoutRoot" Style="{StaticResource PageGridStyle}"> So this is one step in creating consistency in your application’s look.  In future posts I will dig a little deeper. del.icio.us Tags: windows phone 7,mobile development,windows phone 7 development,.NET,software development,design,UX

• How to setup multiple WANs with load balancing?

• Does Fetch as Googlebot still support their ajax-crawling proposal?

  - by Gunchars

  I spent half a day implementing the server side html generation for modal pages based on their proposal (link), but it seems like the Fetch as Googlebot functionality in Webmaster tools completely ignores the URL fragment. I've verified that the _escaped_fragment_ functionality is working on my server (example), but when I submit a URL like /#!/recipes, the Googlebot just fetches /. There aren't any recent confirmations that it's working and, honestly, it wouldn't surprise me if they just silently dropped the functionality without even editing the docs.

• Simple 2 player server

  - by Sourabh Lal

  I have recently started learning javascript and html and have developed simple 2 player games such as tick-tack-toe, battleship, and dots&boxes. However these 2 player games can only be played on one computer (i.e. the 2 players must sit together) However, I want to modify this so that one can play with a friend on a different computer. Any suggestions on how this is possible? Also since I am a beginner please do not assume that I know all the jargon.

  Hi again, I thought I would improve on the previous post by actually putting a decent about of content into the Filetable - this time I used the opensource DMOZ Health document repository which contains 5,880 files inside 220 folders. The files are all html and are pretty small in size. The entire document collection is about 120Mb unzipped and 30Mb zipped. If any one is interested in testing this collection drop me a note and I will upload the dmoz_health repository archive to Skydrive. This time...(read more)

• Why Java's JMF doesn't work in Linux?

  - by Visruth CV

  I got to do some image processing program in java using Linux. I chose to use the JMF for my camera (a webcam) access. But my program is not able to access the camera. But, the jmf works well in Windows. I downloaded jmf from oracle.com and I tried to install it in 'Ubuntu 10.10-the Maverick-released in October 2010 and supported until April 2012'. The downloaded file was a .bin file. I got the below output (last part of the output) when I tried the command provided by oracle /bin/sh ./jmf-2_1_1e-linux-i586.bin. For inquiries please contact: Sun Microsystems, Inc. 4150 Network Circle, Santa Clara, California 95054. LFI# 129621/Form ID#011801 Do you agree to the above license terms?

I checked out the driver of the camera, it is available in the os itself I think because other softwares are able to access the camera (web cam). I tried it on both desktop and laptop, but no effect... Is there any solution for the problem?
