• OT: Airlines and Podcasts

  - by Greg Low

  Those that know me know that I spend an inordinate amount of time on airlines. I also love podcasts, as you can tell from my www.sqldownunder.com site and show. So anything that combines the two is just awesome. Fly With Joe fits that perfectly. Joe D'Eon provides great insights in his show. I was sad last year that he hadn't posted many shows. I've also been quiet for a couple of months (but that's about to change with a bunch of SQL Server 2008 R2 shows). But I've been so pleased that Joe's got...(read more)

• How to control CPU frequency

  - by Tim

  I am using CPU Frequency Scaling Monitor 2.30.0 on the panel to show and control CPU frequency. My CPU frequency by default will change according to load. But I want to make CPU work at the lowest level and so I choose 800 MHz in CPU Frequency Scaling Monitor. After a few seconds, however, it automatically changes back to Powersave or Performance mode which has automatic adjustment to CPU frequency. I was wondering how to actually make CPU work at the lowest level? Thanks!

• Tips or techniques to use when you do't know how to code something?

  - by janoChen

  I have a background as UI designer. And I realized that it is a bit hard for me to write a pieces of logic. Sometimes I get it right, but most of the time, I end up with something hacky (and it usually takes a lot of time). And is not that I don't like programming, in fact, I'm starting to like it as much as design. It's just that sometimes I think that I'm better at dealing with colors an shapes, rather than numbers and logic (but I want to change that). What I usually do is to search the solution on the Internet, copy the example, and insert it into my app (I know this is not a very good practice). I've heard that one tip was to write the logic in common English as comment before writing the actual code. What other tips and techniques I can use?

• Should page contents same all time for SEO?

  - by Ahmet Kemal

  Hi, I have a frequently updated website. That's why page contents change frequently. I mean the items that are on 1'st page become on 2'nd page a day after. Similarly 192'nd page which is my last page becomes 193'rd page a day after. So Google finds different content on a specific page than its previous visit. Is it bad for SEO? My main page is http://www.yemeklog.com/home/ and as you see below page pagination pages are like http://www.yemeklog.com/home/10 or http://www.yemeklog.com/home/192 . Website content is about food receipes at all pages. What you think about it?

• dynamic urls and links on one web page

  - by John

  I am trying to figure out how to create dynamic links and urls on a static webpage. What I want to do is the following: I have a single webpage for example: MYWEBPAGEdotCOM/INDEX.HTML that will always look the same, except for one link on the page. the link would be on the page for example: LINK TO AFFILIATE: affiliatedotCOM/my-affiliate_code_here_DYNAMIC_REFERER the only thing would change is the "DYNAMIC_REFERER" with every dynamic url on this page: MYWEBPAGEdotCOM/INDEX.PHP_id=test1 MYWEBPAGEdotCOM/INDEX.PHP_id=test2 MYWEBPAGEdotCOM/INDEX.PHP_id=test3 MYWEBPAGEdotCOM/INDEX.PHP_id=test4 which would only hange the dynamic link on the page to: affiliatedotCOM/my-affiliate_code_here_test1 affiliatedotCOM/my-affiliate_code_here_test2 affiliatedotCOM/my-affiliate_code_here_test3 affiliatedotCOM/my-affiliate_code_here_test4 Can someone tell me how I could go about doing this? I just dont want to have to make 100's of pages, as this would prevent me from having to do so.

• How do I remove webapps completely?

  - by user104106

  I'd like to be able to remove webapps from my system, I don't want any of the packages associated with it. But trying to remove it I am told there are several other packages that require it. Please change this, I don't like the idea of webapps and I want it gone. I'm tired of getting annoying popups that don't explain anything asking me to install something! It feels like a huge security breach and the user is given no information as to what they are choosing. This is a very bad decision on Canonicals part. I should be working for them, something like this would never ship.

• Is Google Closure a true compiler?

  - by James Allardice

  This question is inspired by the debate in the comments on this Stack Overflow question. The Google Closure Compiler documentation states the following (emphasis added): The Closure Compiler is a tool for making JavaScript download and run faster. It is a true compiler for JavaScript. Instead of compiling from a source language to machine code, it compiles from JavaScript to better JavaScript. However, Wikipedia gives the following definition of a "compiler": A compiler is a computer program (or set of programs) that transforms source code written in a programming language (the source language) into another computer language... A language rewriter is usually a program that translates the form of expressions without a change of language. Based on that, I would say that Google Closure is not a compiler. But the fact that Google explicitly state that it is in fact a "true compiler" makes me wonder if there's more to it. Is Google Closure really a JavaScript compiler?

• 12.04 - Connecting Acer X203H monitor to new Dell XPS 15z laptop

  - by Lucy Dixon

  I have installed the latest version of Ubuntu (12.04) on my boyfriend's new Dell XPS 15z laptop. He uses a Microsoft wireless keyboard and mouse, and an Acer X203H monitor with his set-up. No problems with the keyboard or mouse, or with connecting the HP printer, but we just can't get the laptop to talk to the Acer monitor. With his old setup he used a VGA cable to connect machine & monitor. New laptop has no VGA port, but we've bought a VGA to HDMI adaptor to connect to the laptop. Have tried using Fn F2 to change the display from laptop to monitor, but it doesn't see the monitor at all. HELP! Is there a driver I can install from somewhere? Or how can I tell Ubuntu to look for the monitor on another port? Completely in the dark, and about to get in trouble!! Thanks

• Error pages in ASP.NET

  - by koevoeter

  In ASP.NET you can retrieve the last unhandled exception via:(HttpContext.Current.)Server.GetLastError() // Server object is available as a property in Page and UserControl context This obviously only works in the same roundtrip. If you want to retrieve this information in your error page, you got a problem because the error page is not returned in the same roundtrip. The server responds with a redirect response and a new request to the error page is automatically sent. A common workaround would be to store the exception in your Session state from the Application_Error event in Global.asax. From ASP.NET 3.5 you can configure the redirect mode for error pages: <customErrors mode="On" defaultRedirect="~/Error.aspx" redirectMode="ResponseRewrite" /> This way the redirect response is not sent and the error page is returned right away. That implies that the browser is not aware of a page change and cannot reflect it in the address bar, so your original URL is not replaced with the URL of the error page, which might be what you actually want…

• Why is trailing whitespace a big deal?

  - by EpsilonVector

  Trailing whitespace is enough of a problem for programmers that editors like Emacs have special functions that highlight it or get rid of it automatically, and many coding standards require you to eliminate all instances of it. I'm not entirely sure why though. I can think of one practical reason of avoiding unnecessary whitespace, and it is that if people are not careful about avoiding it, then they might change it in between commits, and then we get diffs polluted with seemingly unchanged lines, just because someone removed or added a space. This already sounds like a pretty good reason to avoid it, but I do want to see if there's more to it than that. So, why is trailing whitespace such a big deal?

• Getting PHP to work with apache to run .php files through browser [closed]

  I have VPS running Debian 5.0 (I think) and I would like to get it to run PHP files. I was told it needed to be configured with Apache. I tried entering the command apt-get install apache2 php5 libapache2-mod-php5. But there was no change. Console output: http://pastebin.com/sVMWq6mA This is everything in my /etc/apache2/mods-enabled: http://img35.imageshack.us/img35/6474/modsb.jpg My webserver can be accessed here: http://206.217.223.136/test/ In my test.php file I have the code : <?php phpinfo(); ?> but instead of displaying the page, it tries to download it. How can I fix this?

• How to set Default Web Browser, Mail Client, Video Player & Music Player in the system

  - by Luis Alvarado

  I am trying to find the option that sets, for the whole system the default Web Browser, Mail Client, Video Player and Music Player instead of having to do it for each type of file. I knew where the option was in 11.04 but somehow I can not find it again. Just to not get anymore confused I am not talking about right clicking a file then changing the "Open With" to the one I want. The option I am looking for affects everything in general, so if I change, for example, the default video player to VLC, all movies will be watched with VLC. I am using Unity.

• Cannot Unbind Super Key from Unity

  - by Tom Thorogood

  Due to a graphics card compatibility issue using CrunchBang, I was told that my best option would be to move to 12.04 LTS. I'm trying to get everything configured and personalized the way I'm used to things, but am having some issues with unbinding default Unity shortcuts. I'm used to having all my shortcuts routed through the super key (T for Terminal, W for Web, Up for increased opacity, and so on). I've followed instructions to install compizconfig-settings-manager, and did an advanced search for all keyboard shortcuts binding to the super key, including the Unity shortcuts, but Unity still seems to listen for that keypress, and thus neither compiz nor the keybindings set up in system prefs - keyboard receive the commands I give them. (I did try also to simply change the unity launcher key instead of disabling it as shown below -- neither worked)

• Configuration data: single-row table vs. name-value-pair table

  - by Heinzi

  Let's say you write an application that can be configured by the user. For storing this "configuration data" into a database, two patterns are commonly used. The single-row table CompanyName | StartFullScreen | RefreshSeconds | ... ---------------+-------------------+------------------+-------- ACME Inc. | true | 20 | ... The name-value-pair table ConfigOption | Value -----------------+------------- CompanyName | ACME Inc. StartFullScreen | true (or 1, or Y, ...) RefreshSeconds | 20 ... | ... I've seen both options in the wild, and both have obvious advantages and disadvantages, for example: The single-row tables limits the number of configuration options you can have (since the number of columns in a row is usually limited). Every additional configuration option requires a DB schema change. In a name-value-pair table everything is "stringly typed" (you have to encode/decode your Boolean/Date/etc. parameters). (many more) Is there some consensus within the development community about which option is preferable?

• Synaptic opens with "starting without Administrative privileges

  - by Uri Herrera

  When I try to open Synaptic from the AWN Cardapio applet menu it gives me the 'starting without administrative privileges' message and then I can't install anything. I can run sudo synaptic and it works fine, but how can I get it to just prompt me for my password like it used to? I don't like having to open terminal just to open synaptic. Any ideas? im using AWN Cardapio Applet and not the GNOME panel classic menu, so i can't just change the command in the menu, like in the classic one.

• Five new junior developers and lots of complex tasks. What's now?

  - by mxe

  Our company has hired five new junior developers to help me to developer our product. Unfortunately the new features and incoming bug fixes usually require deeper knowledge than a recently graduated developer usually has (threading/concurrency, debugging performance bottlenecks in a complex system, etc.) Delegating (and planning) tasks which they (probably) can solve, answering their questions, mentoring/managing them, reviewing their code use up all of my time and I often feel that I could solve the issues less time than the whole delegating process takes (counting only my time). In addition I don't have time to solve the tasks which require deeper system knowledge/more advanced skills and it does not seem that it will change in the near future. So, what's now? What should I do to use their and my time effectively?

• Running 32-bit SSIS in a 64-bit Environment

  - by John Paul Cook

  After my recent post on where to find the 32-bit ODBC Administrator on a 64-bit SQL Server, a new question was asked about how to get SSIS to run with the 32-bit ODBC instead of the 64-bit ODBC. You need to make a simple configuration change to the properties of your BIDS solution. Here I have a solution called 32bitODBC and it needs to run in 32-bit mode, not 64-bit mode. Since I have a 64-bit SQL Server, BIDS defaults to using the 64-bit runtime. To override this setting, go to the property pages...(read more)

• Data binding directly to a store query (DbSet, DbQuery, DbSqlQuery) is not supported.

  - by Chandradev

  HiI was doing some test with code first approach in EF. Then while populating the Gridview i was getting error like thisData binding directly to a store query (DbSet, DbQuery, DbSqlQuery) is not supported. Instead populate a DbSet with data, for example by calling Load on the DbSet, and then bind to local data. For WPF bind to DbSet.Local. For WinForms bind to DbSet.Local.ToBindingList().For solving this error we have to write the code like this private void FillGrid()        {            using (var Context = new EmpDatabaseContext())            {                var query = Context.Emps.Select(m => m);                //var query = from m in Context.Emps                //            select m;               // Gridview1.DataSource = query;                Gridview1.DataSource = query.ToList();                Gridview1.DataBind();            }        }  We canot bind Iqueryable directly. We have to change into ToList()
