  • SOLVED Install MythTV & 11.10 on Lenovo S12 (Intel atom) with wireless

    - by keepitsimpleengineer
    This is how I installed Ubuntu 11.10 and MythTV client on my Lenovo S12 (Intel Atom) laptop and use it using WiFi (see additional notes at end). I did this because the upgrade from 11.04 bricked the laptop. Note that the partitions on the Lenovo standard disk were already in place for this installation. Also note that my LAN is setup for fixed IP addresses. Downloaded and burned 11.10 x86 Desktop Ubuntu CD Connected the power supply cord, LAN wire and the external DVD USB drive. Ran Windows XP and made sure performance level "Performance" was set and "Wireless" was enabled. Booted S12 from CD Disabled Networking from icon on upper left panel icon Edited Connections… "Wired connection 1" ? Set IP address, accepted default netmask and set gateway. Also set DNS server. Good idea to check "Connection Information" here to verify everything's O.K. Selected Install Ubuntu from the initial "Install" window Verified the three items were checked (required disk space available, plugged into a power source, & connected to the Internet) Selected Download updates while installing and third party software. Hit Continue… At wireless selected don't want to connect…WiFi…now. Continue… At Installation type, selected Something else. Continue… At partition tale, selected the ext4 Linux partition, set the mount point as "/", and marked for formatting. Here I selected the main disk (/sda) for installing the boot manager. Continue… Selected or verified my Time zone. Continue… Selected my keyboard layout. Continue… Filled in the who are you fields. Make sure password is required to sign in is checked. Continue… Chose a picture. Continue… I selected import no accounts. Continue… Wait as the Install creeps along. If your screen goes blank, tap the space bar ? apparently the screen saver/power plan does this. There are several progress bars. The longest was "Installing system", and it was the next to the last one. Installation Complete window appears, Restart Now… Wait as it stops, The screen blanks then the message "…remove…media…close tray…press enter" I just unplugged the USB DVD and hit enter… It was disheartening but the screen turned Ubuntu Purple-beige and nothing happened, so I help down the power key until it shut down, the pressed it again and the Grub Boot screen appeared. Select Ubuntu… 25.The screen went blank with the little flashing underscore cursor on it and the disk light would occasionally flash. I hit the enter key and eventuality Ubuntu started. After a somewhat long time the unity desktop appeared. 11.10, unlike earlier versions, retains the connection information. Check this by checking the network icon on the upper left applet panel. Here the touch-pad·mouse quit working and I had to reboot. It takes and extremely long time to boot, sometimes requiring several power off/ power on (cold boot). You can try to get the default network manager to work, but it might not, it didn't on mine for WiFi. Thanks to: Chris at URL here's what to do… disconnect your wired Internet connection. input your wireless information into network manager open a terminal (unity dash, top of icon totem, open, and make sure the ruler&pen icon on the bottom is selected, 2nd from left) type in "terminal". Might be a good idea to drag and drop the terminal icon to the terminal, it's easy to get rid of later. click to open a terminal, and type in: sudo rmmod acer_wmi && echo "blacklist acer_wmi" >> /etc/modprobe.d/blacklist.conf and hit enter. type in your password as asked. if you have correctly entered your WiFi information and you are near your AP, you should connect immediately if not, see the URL above ? you might need to replace "network manager" with "wicd" ? I did with 11.04. Update the new 11.10, in the upper left panel applet weird·gear icon is menu with a line about updating. It's the new way to invoke Update Manager. Your lenovo S12 (intel atom) should now run the new unity Ubuntu. Point your elbow at the ceiling and pat yourself on the back.

Click Install… You will need your password. Debconf window will open, select by making sure check mark is in the little box "Would you like to activate…". Forward… Which version? At the time of writing the current "Stable" version was 24.1, select 0.24.x… Forward… Read the message, then forward… Delete the downloaded file. Install synaptic (unity dash, top of icon totem, open, and make sure the ruler&pen icon on the bottom is selected, 2nd from left) type in "synaptic". Click on the synaptic icon.

Might be a good idea to drag and drop the terminal icon to the terminal, it's easy to get rid of later. Run synaptic, read the intro, and close the intro window. Type in mythbuntu-control-centre in the Quick filter text box, and then select it "Mark for installation" by clicking on the box next to it's name. Marvel at the additional to be installed items, then select "?Mark"… At the top of the synaptic window click on the "? Apply" button. Marvel at the amount of stuff to be installed, the click on "Apply". When finished, close finished window and synaptic. Open mythbuntu-control-centre (unity dash, top of icon totem, open, and make sure the ruler&pen icon on the bottom is selected, 2nd from left) type in "mythbuntu".

Setup General Database Configuration 1/2 Password:~? Enter this Hit Alt-n to go to the next page. Select "Use custom id…", then enter a custom ID, I use the machine's name. Hit finish, and MythTV should start up with all default settings. For the lenovo S12, the first thing you want to do is to set Playback profiles to "Normal". From Setup TV Settings Playback Alt-N(ext) Alt-N(ext) Playback Profiles (3/8) : Change Current Video Playback Profile to "Normal". You can fiddle with this setting later. For the lenovo S12, the second thing is to get the sound going. From Setup General Alt-N(ext) Alt-N(ext) Alt-N(ext) Audio System: The top of the screen is a button title "Scan for audio devices", move the highlight there and press the Space bar. Then Tab down to Audio Output Device: and left-right arrow until "ALSA:hw:Card=Intel,DEV=0" is selected. Then Alt-N(ext) until "Finish". Now you should have sound. You should now have MythTV working nicely on the Lenovo S12 Notes about wireless: Running Lenovo S12 on wireless is demanding on both power and WiFi connection.

  • Complex SQL query help on aggregating values for nested subquery

    - by François Beausoleil
    Hi! I have people, companies, employees, events and event kinds. I'm making a report/followup sheet where people, companies and employees are the rows, and the columns are event kinds. Event kinds are simple values describing: "Promised Donation", "Received Donation", "Phoned", "Followed up" and such. Event kinds are ordered: CREATE TABLE event_kinds ( id, name, position); Events hold the actual reference to the event: CREATE TABLE events ( id, person_id, company_id, referrer_id, event_kind_id, created_at); referrer_id is another reference to people. It is the person which sent the information/tip along, and is an optional field, although I sometimes want to filter on an event_kind that has a specific referrer, while I don't for other event kinds. Notice I don't have an employee ID reference. The reference exists, but is implied. I have application code to validate that person_id and company_id really reference an employee record. The other tables are pretty basic: CREATE TABLE people ( id, name); CREATE TABLE companies ( id, name); CREATE TABLE employees ( id, person_id, company_id); I'm trying to achieve the following report: Referrer Phoned Promised Donated Francois Feb 16th Feb 20th Mar 1st Apple (Steve Jobs) Steve Ballmer Mar 3rd IBM Bill Gates Mar 7th The first row is a people record, the 2nd is an employee, and the 3rd is a company. If I asked for referrer Bill Gates for Phoned event kinds, I'd only see the 3rd row, while asking for Steve and Phoned would return no rows. Right now, I do 3 queries, one for companies, one for people and a last one for employees. I want the event kind columns to be ordered, but I do that in application code and show it properly there. Here's where I'm at so far: SELECT companies.id, companies.name, (SELECT events.id FROM events WHERE events.referrer_id = 1470 AND events.company_id = companies.id AND events.person_id IS NULL AND events.event_kind_id = 9 ORDER BY created_at DESC LIMIT 1) event_kind_9, (SELECT events.id FROM events WHERE events.company_id = companies.id AND events.person_id IS NULL AND events.event_kind_id = 10 ORDER BY created_at DESC LIMIT 1) event_kind_10, (SELECT events.created_at FROM events WHERE events.referrer_id = 1470 AND events.company_id = companies.id AND events.person_id IS NULL AND events.event_kind_id = 9 ORDER BY created_at DESC LIMIT 1) event_kind_9_order FROM "companies" SELECT people.id, people.name, (SELECT events.id FROM events WHERE events.referrer_id = 1470 AND events.company_id IS NULL AND events.person_id = people.id AND events.event_kind_id = 9 ORDER BY created_at DESC LIMIT 1) event_kind_9, (SELECT events.id FROM events WHERE events.company_id IS NULL AND events.person_id = people.id AND events.event_kind_id = 10 ORDER BY created_at DESC LIMIT 1) event_kind_10, (SELECT events.created_at FROM events WHERE events.referrer_id = 1470 AND events.company_id IS NULL AND events.person_id = people.id AND events.event_kind_id = 9 ORDER BY created_at DESC LIMIT 1) event_kind_9_order FROM "people" SELECT employees.id, employees.company_id, employees.person_id, (SELECT events.id FROM events WHERE events.referrer_id = 1470 AND events.company_id = employees.company_id AND events.person_id = employees.person_id AND events.event_kind_id = 9 ORDER BY created_at DESC LIMIT 1) event_kind_9, (SELECT events.id FROM events WHERE events.company_id = employees.company_id AND events.person_id = employees.person_id AND events.event_kind_id = 10 ORDER BY created_at DESC LIMIT 1) event_kind_10, (SELECT events.created_at FROM events WHERE events.referrer_id = 1470 AND events.company_id = employees.company_id AND events.person_id = employees.person_id AND events.event_kind_id = 9 ORDER BY created_at DESC LIMIT 1) event_kind_9_order FROM "employees" I rather suspect I'm doing this wrong. There should be an "easier" way to do it. One other filter criteria would be to filter on people/company names: WHERE LOWER(companies.name) LIKE '%apple%'. Note that I'm ordering by the dates of event_kind_9 here, and a secondary sort is by person/company name. To summarize: I want to paginate the result set, find the latest event for each cell, order the result set by the date of the latest event, and by company/person name, filter by referrer in some event kinds, but not others. For reference, I'm using PostgreSQL, from Ruby, ActiveRecord/Rails. The solution is pure SQL though.

  • Can VS2010 help me find memory leaks?

    - by Andrew Garrison
    I'm going through the pain right now of finding memory leaks in my application using WinDbg. Luckily, I've found a few good articles that give a very good step-by-step process of how to do it. Still, it is a fairly painful process. Does VS2010 have any built in features that can ease the burden of finding a memory leak in a Silverlight application? Of course, a memory leak in .NET sounds a bit like a misnomer, but what I intend to do is to find all objects that are still referencing an object that I believe should be garbage collected. For those that may be interested, here are some good articles on how to get started using WinDbg to find memory leaks in Silverlight: Finding Memory Leaks In Silverlight With WinDbg Hunting down memory leaks in Silverlight

  • ASP.NET XML as Datasource error

  • ASP.NET MVC 2 "value" in DataAnnotation attribute passed is null, when incorrect date is submitted.

    - by goldenelf2
    Hello to all! This is my first question here on stack overflow. i need help on a problem i encountered during an ASP.NET MVC2 project i am currently working on. I should note that I'm relatively new to MVC design, so pls bear my ignorance. Here goes : I have a regular form on which various details about a person are shown. One of them is "Date of Birth". My view is like this <div class="form-items"> <%: Html.Label("DateOfBirth", "Date of Birth:") %> <%: Html.EditorFor(m => m.DateOfBirth) %> <%: Html.ValidationMessageFor(m => m.DateOfBirth) %> </div> I'm using an editor template i found, to show only the date correctly : <%@ Control Language="C#" Inherits="System.Web.Mvc.ViewUserControl<System.DateTime?>"%> <%= Html.TextBox("", (Model.HasValue ? Model.Value.ToShortDateString() : string.Empty))%> I used LinqToSql designer to create my model from an sql database. In order to do some validation i made a partial class Person to extend the one created by the designer (under the same namespace) : [MetadataType(typeof(IPerson))] public partial class Person : IPerson { //To create buddy class } public interface IPerson { [Required(ErrorMessage="Please enter a name")] string Name { get; set; } [Required(ErrorMessage="Please enter a surname")] string Surname { get; set; } [Birthday] DateTime? DateOfBirth { get; set; } [Email(ErrorMessage="Please enter a valid email")] string Email { get; set; } } I want to make sure that a correct date is entered. So i created a custom DataAnnotation attribute in order to validate the date : public class BirthdayAttribute : ValidationAttribute { private const string _errorMessage = "Please enter a valid date"; public BirthdayAttribute() : base(_errorMessage) { } public override bool IsValid(object value) { if (value == null) { return true; } DateTime temp; bool result = DateTime.TryParse(value.ToString(), out temp); return result; } } Well, my problem is this. Once i enter an incorrect date in the DateOfBirth field then no custom message is displayed even if use the attribute like [Birthday(ErrorMessage=".....")]. The message displayed is the one returned from the db ie "The value '32/4/1967' is not valid for DateOfBirth.". I tried to enter some break points around the code, and found out that the "value" in attribute is always null when the date is incorrect, but always gets a value if the date is in correct format. The same ( value == null) is passed also in the code generated by the designer. This thing is driving me nuts. Please can anyone help me deal with this? Also if someone can tell me where exactly is the point of entry from the view to the database. Is it related to the model binder? because i wanted to check exactly what value is passed once i press the "submit" button. Thank you.

  • Hashing words to numbers with respect to definition

    - by thornate
    As part of a larger project, I need to read in text and represent each word as a number. For example, if the program reads in "Every good boy deserves fruit", then I would get a table that converts 'every' to '1742', 'good' to '977513', etc. Now, obviously I can just use a hashing algorithm to get these numbers. However, it would be more useful if words with similar meanings had numerical values close to each other, so that 'good' becomes '6827' and 'great' becomes '6835', etc. As another option, instead of a simple integer representing each number, it would be even better to have a vector made up of multiple numbers, eg (lexical_category, tense, classification, specific_word) where lexical_category is noun/verb/adjective/etc, tense is future/past/present, classification defines a wide set of general topics and specific_word is much the same as described in the previous paragraph. Does any such an algorithm exist? If not, can you give me any tips on how to get started on developing one myself? I code in C++.

  • What's wrong with the analogy between software and building construction?

    - by kuosan
    Many people like to think of building software as constructing a building so we have terms like building blocks and architecture. However, lately I've been to a couple of talks and most people say this analogy is wrong especially around the idea of having a non-coding software architect in a project. In my experience, good software architects are those who also write code so they won't design things that only looks good on paper. I've worked with several Architecture Astronauts, who have either limited or outdated experience in programming. These architecture astronauts quite often missed out critical details in their design and cause more harm than good in a project. This makes me wonder what are the differences between constructing a software and a building? How come in the building industry they can have architects who probably never build a house in their life and purely handles design work but not in the software development field?

  • How to migrate data from a Firebird database to PostGreSQL on Linux

    - by Tom Feiner
    Are there any good tools to migrate existing firebird databases to PostgreSQL for Linux systems? I've looked at: FBexport which can be used to dump the data as insert statements, but it's mainly written to export/import from one firebird db to another, not as a migration tool. There's also: Firebird to PostgreSQL Win32 tool, but it's only for win32 systems. Is there any good tool to do this? Or should I just roll my own?

  • Is there anything RAD comparable to VCL?

    - by mawg
    After years in embedded programming, I have to develop a Windows app. I dug out my old C++ Builder and Delphi. These are great and the latest version costs over $1k, so I won't be going there. What I prarticularly like is the VCL (visual component library) which let's me code my own components and share them with others, plus the thousands of existing 3rd party components. I noticed that there is now also a RAD PHP from Borland too. I realzie that MSVC, QT, NetBeans, etc are good enough IDEs for RAD, BUT does anything offer the ease of the Borland products for developing additional components - and does anything else have thousands to choose from? PC based? Cross-platform is good. Browser based? Free is always good ;-) I don't particularly care about the programming language.

Because seen from the example above: Steven has 2 phone number and 3 emails. The JOIN Emails with Numbers happens with each email - thus duplicated values that can not be sorted (SORT BY does not work on them). **THIS IS WHAT I WANT** +----------+---------+-----------------+------------------------------+ | Name | ID | Number | Email | +----------+---------+-----------------+------------------------------+ | Steven | 5000008 | 8451384 | [email protected] | | | | 24887312 | [email protected] | | | | | [email protected] | | John | 5000005 | 5551234 | [email protected] | | | | 5154324 | [email protected] | | George | 5000004 | NULL | [email protected] | | Ashley | 8000009 | 7134584 | [email protected] | | Amy | 5000003 | NULL | NULL | +----------+---------+-----------------+------------------------------+ Now I'm told that it's best to keep emails and number in separated tables because one can have many emails. So if it's such a common thing to do, what isn't there a simple solution? I'd be happy with a PHP Solution aswell. What I know how to do by now that satisfies it, but is not as pretty. If I do it with GROUP_CONTACT I geat a satisfactory result, but it doesn't look as pretty: I can't put a "Email type = work" next to it.

  • How to overcome shortcomings in reporting from EAV database?

    - by David Archer
    The major shortcomings with Entity-Attribute-Value database designs in SQL all seem to be related to being able to query and report on the data efficiently and quickly. Most of the information I read on the subject warn against implementing EAV due to these problems and the commonality of querying/reporting for almost all applications. I am currently designing a system where almost all the fields necessary for data storage are not known at design/compile time and are defined by the end-user of the system. EAV seems like a good fit for this requirement but due to the problems I've read about, I am hesitant in implementing it as there are also some pretty heavy reporting requirements for this system as well. I think I've come up with a way around this but would like to pose the question to the SO community. Given that typical normalized database (OLTP) still isn't always the best option for running reports, a good practice seems to be having a "reporting" database (OLAP) where the data from the normalized database is copied to, indexed extensively, and possibly denormalized for easier querying. Could the same idea be used to work around the shortcomings of an EAV design? The main downside I see are the increased complexity of transferring the data from the EAV database to reporting as you may end up having to alter the tables in the reporting database as new fields are defined in the EAV database. But that is hardly impossible and seems to be an acceptable tradeoff for the increased flexibility given by the EAV design. This downside also exists if I use a non-SQL data store (i.e. CouchDB or similar) for the main data storage since all the standard reporting tools are expecting a SQL backend to query against. Do the issues with EAV systems mostly go away if you have a seperate reporting database for querying? EDIT: Thanks for the comments so far. One of the important things about the system I'm working on it that I'm really only talking about using EAV for one of the entities, not everything in the system. The whole gist of the system is to be able to pull data from multiple disparate sources that are not known ahead of time and crunch the data to come up with some "best known" data about a particular entity. So every "field" I'm dealing with is multi-valued and I'm also required to track history for each. The normalized design for this ends up being 1 table per field which makes querying it kind of painful anyway. Here are the table schemas and sample data I'm looking at (obviously changed from what I'm working on but I think it illustrates the point well): EAV Tables Person ------------------- - Id - Name - ------------------- - 123 - Joe Smith - ------------------- Person_Value ------------------------------------------------------------------- - PersonId - Source - Field - Value - EffectiveDate - ------------------------------------------------------------------- - 123 - CIA - HomeAddress - 123 Cherry Ln - 2010-03-26 - - 123 - DMV - HomeAddress - 561 Stoney Rd - 2010-02-15 - - 123 - FBI - HomeAddress - 676 Lancas Dr - 2010-03-01 - ------------------------------------------------------------------- Reporting Table Person_Denormalized ---------------------------------------------------------------------------------------- - Id - Name - HomeAddress - HomeAddress_Confidence - HomeAddress_EffectiveDate - ---------------------------------------------------------------------------------------- - 123 - Joe Smith - 123 Cherry Ln - 0.713 - 2010-03-26 - ---------------------------------------------------------------------------------------- Normalized Design Person ------------------- - Id - Name - ------------------- - 123 - Joe Smith - ------------------- Person_HomeAddress ------------------------------------------------------ - PersonId - Source - Value - Effective Date - ------------------------------------------------------ - 123 - CIA - 123 Cherry Ln - 2010-03-26 - - 123 - DMV - 561 Stoney Rd - 2010-02-15 - - 123 - FBI - 676 Lancas Dr - 2010-03-01 - ------------------------------------------------------ The "Confidence" field here is generated using logic that cannot be expressed easily (if at all) using SQL so my most common operation besides inserting new values will be pulling ALL data about a person for all fields so I can generate the record for the reporting table. This is actually easier in the EAV model as I can do a single query. In the normalized design, I end up having to do 1 query per field to avoid a massive cartesian product from joining them all together.

    I am planning to get some good book for Windows Socket Programming in VC++. I have 2+ years of experience in working with VC++/ATL/COM/MFC; but not in the networking domain. I have been doing some search in Google for "Windows network programming" books. There are few but they have both good and bad comments scattered all over; and I am not able to decide anything. Please recommend some good book with Pros and Cons. The books I found are below. Windows Sockets Network programming Network Programming for Microsoft Windows Thanks.

  • Flex AdvancedDataGrid with Grouping, how do I get objects to appear under first GroupingField if the

    - by shadenite
    I am using an AdvancedDataGrid with two GroupingFields. The dataProvider has a list of objects with these two field values, but occasionally the second field value can be null. When it loads, the AdvancedDataGrid UI has a root folder (first GroupingField) and some additional subfolders (second GroupingField). This is all good. However, the objects with a null value for the second GroupingField, just get placed in a subfolder with no label. I want the objects with a null second GroupingField value to appear as leaf nodes beneath the root folder (first GroupingField) minus the blank subfolder. A good way to picture this would be a file explorer. Is there a good way to do this? Make the folder icon disappear maybe after expanding this node through actionscript?

  • proftpd: copying uploaded files to an additional directory

    - by Matthew Iselin
    Using proftpd, is there a good way to automatically synchronise uploaded files from the upload directory to some other directory? Our layout ends up a bit like this: ~/ftp/some/path <-- Files are uploaded here ~/some/other/path/not/accessible/via/ftp <-- But also need to be here after uploading Is there a good way to do this automatically, or do I have to tell anyone uploading files to upload twice, and open up an additional directory (containing data we cannot redistribute)?

  • Need to parse HTML document for links-- use a library like html5lib or something else?

    - by Luinithil
    I'm a very newbie webpage builder, currently working on creating a website that needs to change link colours according to the destination page. The links will be sorted into different classes (e.g. good, bad, neutral) by certain user input criteria-- e.g. links with content the user would find of interest is colored blue, stuff that the user (presumably) doesn't want to see is colored as normal text, etc. I reckon I need a way to parse the webpage for links to the content (stored in MySQL database), change the colors for all the links on the page (so I need to be able to change the link classes in the HTML as well) before outputting the adapted page to the user. I read that regex is not a good way to find those links-- so should I use a library, and if so, is html5lib good for what I'm doing?

  • Is there anything RAD comparible to VCL?

    - by mawg
    After years in embedded programmking, I have to develop a windows app. I dug out my old C++ builder and Delphi. These are great and the latest version costs over $1k, so I won't be going there. What I prarticularly like is the VCL (visual component library) which let's me code my own components and share them with others, plus the thousands of existing 3rd party components. I noticed that there is now also a RAD PHP form Borland too. I realzie that MSVC, QT, NetBEans, etc are good enough IDEs for RAD, _BUT_ does anything offer the ease of the Borland products for developing additional components - and does anything else have thousands to choose from? PC based? Cross-platform is good. Browser based? Free is always good ;-) I don't particularly care about the programming language.

  • Export from HTML to PDF (C#)

    - by Sem Dendoncker
    Hi, In our applications we make html documents as reports and exports. But now our customer wants a button that saves that document on their pc. The problem is that the document includes images. You can create a word document with the following code: private void WriteWordDoc(string docName) { Response.Buffer = true; Response.ContentType = "application/msword"; Response.AddHeader("content-disposition", String.Format("attachment;filename={0}.doc", docName.Replace(" ", "_"))); Response.Charset = "utf-8"; } But the problem is that the images are just links an thus not embedded in the word document. Therefore I'm looking for an alternative PDF seems to be a good alternative, does anyone know a good pdf writer for C#? One that has some good references and has been tested properly? Best regards, Sem

  • Fuzzy string matching algorithm in Python

    - by Mridang Agarwalla
    Hi guys, I'm trying to find some sort of a good, fuzzy string matching algorithm. Direct matching doesn't work for me — this isn't too good because unless my strings are a 100% similar, the match fails. The Levenshtein method doesn't work too well for strings as it works on a character level. I was looking for something along the lines of word level matching e.g. String A: The quick brown fox. String B: The quick brown fox jumped over the lazy dog. These should match as all words in string A are in string B. Now, this is an oversimplified example but would anyone know a good, fuzzy string matching algorithm that works on a word level. Thanks in advance.
