  • Getting Started in SuSE as an Ubuntu User

    - by Subhamoy Sengupta
    I am not a Linux newbie, but haven't touched SuSE in a very very long time (last time I tried it, it was SuSE 7!). Finally now I felt like giving it a try, and many things seem strange or unnecessarily complex. I have a series of questions. How do I ensure that my packages are uptodate? It sounds silly, but I tried the obvious methods already. I have disabled the default repositories that show up when you do zypper lr, and added Tumbleweed and packman repositories (Essentials, Multimedia, Extra). Then I did a sudo zypper ref --force and then sudo zypper dup, and it tells me many dependencies are not met. I have already added solder.allowVendorChange=true to /etc/zypp/zypp.conf, so it should not care which repository the latest versions are in, and just upgrade to it. Even when I chose to skip the packages with unmet dependencies, and seemed like quite a bit happened in the background, I opened Firefox afterwards and the version was 7! I am guessing things did not go as expected. But of course this is not a problem with SuSE, but I am not understanding the system right. How do I do it right? When I start typing arguments of a command, for example sudo zypper install, when I type sudo zypper ins and keep hitting TAB, nothing happens! It always worked in Ubuntu and I feel very uneasy with this. Is this how SuSE is supposed to be? When I try to install something, and I start writing its name, even though the package exists and I am sure of it, hitting TAB does not autocomplete it. This is also quite inconvenient. Why is it not happening? There are many things in SuSE that are really great, and I think I will stay with it and not go back to Ubuntu once I settle these very rudimentary issues. But right now they are giving me a lot of grief! Please help!

  • how to refactor user-permission system?

    - by John
    Sorry for lengthy question. I can't tell if this should be a programming question or a project management question. Any advice will help. I inherited a reasonably large web project (1 year old) from a solo freelancer who architected it then abandoned it. The project was a mess, but I cleaned up what I could, and now the system is more maintainable. I need suggestions on how to extend the user-permission system. As it is now, the database has a t_user table with the column t_user.membership_type. Currently, there are 4 membership types with the following properties: 3 of the membership types are almost functionally the same, except for the different monthly fees each must pay 1 of the membership type is a "fake-user" type which has limited access ( different business logic also applies) With regards to the fake-user type, if you look in the system's business logic files, you will see a lot of hard-coded IF statements that do something like if (fake-user) { // do something } else { // a paid member of type 1,2 or 3 // proceed normally } My client asked me to add 3 more membership types to the system, each of them with unique features to be implemented this month, and substantive "to-be-determined" features next month. My first reaction is that I need to refactor the user-permission system. But it concerns me that I don't have enough information on the "to-be-determined" membership type features for next month. Refactoring the user-permission system will take a substantive amount of time. I don't want to refactor something and throw it out the following month. I get substantive feature requests on a monthly basis that come out of the blue. There is no project road map. I've asked my client to provide me with a roadmap of what they intend to do with the new membership types, but their answer is along the lines of "We just want to do [feature here] this month. We'll think of something new next month." So questions that come to mind are: 1) Is it dangerous for me to refactor the user permission system not knowing what membership type features exist beyond a month from now? 2) Should I refactor the user permission system regardless? Or just continue adding IF statements as needed in all my controller files? Or can you recommend a different approach to user permission systems? Maybe role-based ? 3) Should this project have a road map? For a 1 year old project like mine, how far into the future should this roadmap project? 4) Any general advice on the best way to add 3 new membership types?

  • V4L2 and ALSA: Kernel SPI or User API?

    - by pnongrata
    I'm trying to understand what Video for linux and ALSA are (exactly), and I can't discern whether they're APIs for Linux application to use (the userspace) or if they are backend services that are only available to the Linux kernel (sort of a kernalspace SPI). Or, if they are something entirely different. On one hand, those articles make it sound like its an API for applications to use. However, on the V4L2 page it has a section title Software supporting Video4Linux... So is V4L2 a library that applications use, or is it a module that "snaps into" the kernel? I'm so coonfused, thanks in advance.

  • Software to report internet traffic for home user

    - by Mehper C. Palavuzlar
    I need a freeware to monitor my internet activity, especially upload and download amounts over time. For instance, I like to see a graph or table that shows the downloaded and uploaded amounts per day, week or month and in total for a selected period. OS: Windows XP, Vista, 7 Edit: I don't need to see the traffic program by program. I'm not interested in which program accesses the internet, but I'm interested in monitoring my incoming and outgoing data amounts using a light-weight freeware.

  • django getting current user id

    - by dana
    hello, i have a mini app where users can login, view their profile, and follow each other. 'Follow' is a relation like a regular 'friend' relationship in virtual communities, but it is not necessarily reciprocal, meaning that one can follow a user, without the need that the user to be following back that person who follows him. my problem is: if i am a logged in user, and i navigate to a profile X, and push the button follow, how can i take the current profile id ?(current profile meaning the profile that I, the logged in user, am viewing right now.) the view: def follow(request): if request.method == 'POST': form = FollowForm(request.POST) if form.is_valid(): new_obj = form.save(commit=False) new_obj.initiated_by = request.user u = User.objects. what here? new_obj.follow = u new_obj.save() return HttpResponseRedirect('.') else: form = FollowForm() return render_to_response('followme/follow.html', { 'form': form, }, context_instance=RequestContext(request)) thanks in advance!

  • How to track auto-generated id's in select-insert statement

    - by k rey
    I have two tables detail and head. The detail table will be written first. Later, the head table will be written. The head is a summary of the detail table. I would like to keep a reference from the detail to the head table. I have a solution but it is not elegant and requires duplicating the joins and filters that were used during summation. I am looking for a better solution. The below is an example of what I currently have. In this example, I have simplified the table structure. In the real world, the summation is very complex. -- Preparation create table #detail ( detail_id int identity(1,1) , code char(4) , amount money , head_id int null ); create table #head ( head_id int identity(1,1) , code char(4) , subtotal money ); insert into #detail ( code, amount ) values ( 'A', 5 ); insert into #detail ( code, amount ) values ( 'A', 5 ); insert into #detail ( code, amount ) values ( 'B', 2 ); insert into #detail ( code, amount ) values ( 'B', 2 ); -- I would like to somehow simplify the following two queries insert into #head ( code, subtotal ) select code, sum(amount) from #detail group by code update #detail set head_id = h.head_id from #detail d inner join #head h on d.code = h.code -- This is the desired end result select * from #detail Desired end result of detail table: detail_id code amount head_id 1 A 5.00 1 2 A 5.00 1 3 B 2.00 2 4 B 2.00 2

  • Efficiently Serving Dynamic Content in Google App Engine

    - by awegawef
    My app on google app engine returns content items (just text) and comments on them. It works like this (pseudo-ish code): query: get keys of latest content #query to datastore for each item in content if item_dict in memcache: use item_dict else: build_item_dict(item) #by fetching from datastore store item_dict in memcache send all item_dicts to template Sorry if the code isn't understandable. I get all of the content dictionaries and send them to the template, which uses them to create the webpage. My problem is that if the memcache has expired, for each item I want to display, I have to (1) lookup item in memcache, (2) since no memcache exists I must fetch item from the datastore, and (3) store the item in memcache. These calls build up quickly. I don't set an expire time for the entries to the memcache, so this really only happens once in the morning, but the webpage takes long enough to load (~1 sec) that the browser reports it as not existing. Regularly, my webpages take about 50ms to load. This approach works decently for frequent visits, but it has its flaws as shown above. How can I remedy this? The entries are dynamic enough that I don't think it would be in my best interest to cache my initial request. Thanks in advance

  • Does Google crawl AJAX content?

    - by Doug
    On the home page of my site I use JQuery's ajax function to pull down a list of recent activity of users. The recent activity is displayed on the page, and each line of the recent activity includes a link to the user profile of the user who did the activity. Will Google actually make the ajax call to pull down this info and use it in calculating page relevancy / link juice flow? I'm hoping that it does not because the user profile pages are not very Google index worthy, and I don't want all those links to the User profile pages diluting my home page's link juice flow away from other more important links.

  • Ubuntu 10.04 User Interface errors

    - by user306668
    Hi Guys Using Ubuntu 10.04 Beta on a Sony Vaio laptop (slightly old PCG-4n7M). It was working wonderfully until this morning. After updating and upgrading the login screen images gave broken image icons, then on logging in UI was replaced with just the cmd shell. All menus are gone. I have tried to reconfigure xserver-xorg and that doesn't work. Reinstalling doesn't either. I have tried a number of other attempts. What is weird is that I can launch graphical applications from the cmd line. such as firefox or google-chrome. and they work but the UI is simplified or broken (no resizing, closing, minimizing). I am a bit lost on how to fix this error. If anyone has any suggestions, please let me know

  • Weird character at start of json content type

    - by Nek
    Hi, I'm trying to return json content read from MySQL server. This is supposed to be easy but, there is a 'weird' character that keeps appearing at start of the content. I have two pages for returning content: kcb433.sytes.net/as/test.php?json=true&limit=6&input=d this test.php is from a script written by Timothy Groves, which converts an array to json output http://kcb433.sytes.net/k.php?k=4 this one is supposed to do the same I tried to validate it here jsonformatter.curiousconcept.com but just page 1 gets validated, page 2 says that it does not contain JSON data. If accessed directly both pages has no problems. Then what is the difference, why both don't get validated? Then I found this page jsonformat.com and tried the same thing. Page 1 was ok and page 2 wasn't but, surprisingly the data could be read. At a glance, {"a":"b"} may look good but there is a character in front. According to a hex editor online, this is the value of the string above (instead of 9 values, there are 10): -- 7B 22 61 22 3A 22 62 22 7D The code to echo json in page 2 is: header("Content-Type: application/json"); echo "{\"a\":\"b\"}";

  • Datepicker BeforeShowDay CSS problem with content styling

    - by Darklomba
    I think I'm not the only one having this problem. Whenever I try to apply a BeforeShowDay a new CSS class, the content of the "special date" is not being modified. I tried changing the default theme, adding a new class, but this is affecting only the outside border and not the inside content. Using Firebug I found that the html code being printed is the following: <td class=" ui-state-content ui-state-anulados" onclick="DP_jQuery.datepicker._selectDay('#datepicker',9,2009, this);return false;" title="Paddle"> <a class="ui-state-default" href="#">16</a> </td> So, my class would be ui-state-content ui-state-anulados but I notice that the ui-state-default class is being applied automatically and I suspect that this may be the problem. I really don't know how to solve this. I've been looking inside ui.datepicker.js code and I think I found the line that is giving me this problems. It is line number 1394 and it has the following code. (ui.datepicker.js) (unselectable ? '<span class="ui-state-default">' + printDate.getDate() + '</span>' : '<a class="ui-state-default' + Any clues on how this can be done? Thanks in advance. Manuel.-

  • Ubuntu server 12.04 on AWS - How does the passwordless sudo work for the ubuntu user?

    - by aychedee
    I'm using Ubuntu server 12.04 on Amazon. I want to add a new user that has the same behaviour as the default ubuntu user. Specifically I want passwordless sudo for this new user. So I've added a new user and went to edit /etc/sudoers (using visudo of course). From reading that file it seemed like the default ubuntu user was getting it's passwordless sudo from being a member of the admin group. So I added my new user to that. Which didn't work. Then I tried adding the NOPASSWD directive to sudoers. Which also didn't work. Anyway, now I'm just curious. How does the ubuntu user get passwordless privileges if they aren't defined in /etc/sudoers. What is the mechanism that allows this?

  • asp.net master page/content page interaction with style sheet

    - by Matt
    Learning how to do a master page in asp.net. Trying to figure out how my style sheet interacts with respects to the master page and content page. I can get HTML tags like body and the style sheet to react. But when I call the ID attribute of a label no styling takes place. What am I missing here as far as interaction? BTW I'm using VS2008 CSS sample: body { height:1200px; width:920px; border-style:solid; border-color:blue; padding:10px 10px 10px 10px; } #toptext1 { position:relative; top:-225px; right:-500px; font-size:22px; font-weight:bold; } From the master page: <body> <form id="form1" runat="server"> <asp:image id="cookNookLogo" ImageUrl="images/Logo.gif" runat="server" AlternateText="CookNook" Width="449px"></asp:image> <p> <asp:Label ID="toptext1" runat="server" Text="Quality Recipes, Hints and Supplies"></asp:Label> </p> From the content page: <%@ Page Language="C#" MasterPageFile="~/CNMasterPage.master" AutoEventWireup="true" CodeFile="Home.aspx.cs" Inherits="Home" Title="Untitled Page" %> <asp:Content ID="Content1" ContentPlaceHolderID="head" Runat="Server"> <link href="App_Themes/cn/cn.css" rel="stylesheet" type="text/css" /> </asp:Content> When I was doing this without a master page it worked so where am I going wrong with the attributes?

  • Scala case class generated field value

    - by Petteri Hietavirta
    I have an existing Scala application and it uses case classes which are then persisted in MongoDB. I need to introduce a new field to a case class but the value of it is derived from existing field. For example, there is phone number and I want to add normalised phone number while keeping the original phone number. I'll update the existing records in MongoDB but I would need to add this normalisation feature to existing save and update code. So, is there any nice shortcut in Scala to add a "hook" to a certain field of a case class? For example, in Java one could modify setter of the phone number.

  • Passing ASP.NET User by Dependency Injection

    - by UpTheCreek
    In my web application I have various components that need to access the currently authenticated user (HttpContext.User). There are two obvious ways a component can access this: 1) Accessing getting the User from HttpContext.Current 2) Passing the user around in constructors Is not ideal because it makes testing difficult and ties application components to web concerns, when they really shouldn't know about it. Is just messy and complicates everything. So I've been thinking about passing in the current user (or perhaps just the name/id) to any component that needs it using an IoC container (via dependency injection). Is anyone using this technique to supply the current ASP.NET user to parts of the application? Or, Does this sound like a sensible approach? I would like know how this has worked out for people. Thanks
