  • Ubuntu: Resize the root LVM(2?) partition

    - by user12259
    I have an Ubuntu virtual machine running in VirtualBox 2.2.4, and I created it on an 8gb virtual disk which is too small. So, I am trying to increase the size of the disk. So far, I have done this: Created a new larger virtual disk Added the 2nd disk to the machine Used CloneZilla to clone the first disk onto the 2nd disk Removed the first disk Booted up off the 2nd (larger disk) But now I'm still stuck with an 8gb partition on my new 100gb virtual disk. Whats the easiest path from here to having a 100gb partition? :) I gather GPart can resize partitions, but it doesn't seem to support LVM2 partitions, which mine seems to be. thx Alex

  • how to find out what is causing huge dentry_cache usage?

    - by Piavlo
    Note that inode_cache & ext3_inode_cache slabs are very small compared to dentry_cache. What happens is that slowly and steadily the within a week dentry_cache grows from 1M to ~5-6G Then I need to run echo 2 > /proc/sys/vm/drop_caches && echo 0 > /proc/sys/vm/drop_caches This started to happening one day on all servers hosting some web code - the developers are saying that they have not changed anything related to filesystem access pattern around the time then the problem started. The system is centos5 with 2.6.18 kernel so I don't have any instrumentation features available th newer kernels. Any I idea how I can debug the problem? maybe with systemtap? This is a ec2 instance - so not even sure that systemtap will work there. Thanks Alex

  • WPF Binding Error reported when Binding appears to work fine

    - by Noldorin
    I am trying to create a custom TabItem template/style in my WPF 4.0 application (using VS 2010 Pro RTM), but inspite of everything seeming to work correctly, I am noticing a binding error in the trace window. The resource dictionary XAML I use to style the TabItems of a TabControl is given in full here. (Just create a simple TabControl with several items and apply the given ResourceDictionary to test it out.) Specifically, the error is occurring due to the following line (discovered through trial and error testing, since Visual Studio isn't actually reporting it at design tim <TranslateTransform X="{Binding ActualWidth, ElementName=leftSideBorderPath}"/> The full error given in the trace (Ouput window) is the following: System.Windows.Data Error: 2 : Cannot find governing FrameworkElement or FrameworkContentElement for target element. BindingExpression:Path=ActualWidth; DataItem=null; target element is 'TranslateTransform' (HashCode=35345840); target property is 'X' (type 'Double') The error occurs on load and is repeated 5 times then (note that I have 3 tab items in my example). It also occurs consistently and repeatedly whenever for the Window is resized, for example - filling the Output window. Perhaps every time the TabItem layout is updated? And again, though it is not reported, the error very much seems to be due to the fact that I am binding to any element at all, not specifically leftSideBorderPath or the the ActualWidth propertry. For example, changing this line to the following fixes things. <TranslateTransform X="25"/> Unfortunately, hard-coding the value isn't really an option. This issue seems very strange to me in that the binding does appear to be giving the correct results. (Inspecting the X value of the TranslateTransform at runtime clearly shows the correct bound value, and the ClipGeometry when viewed is exactly what it hsould be.) Neither Visual Studio nor WPF seems to be giving me any more information on the cause of the error perhaps (setting PresentationTraceSources.TraceLevel to High doesn't help), yet the fact that things are working despite the error being reported inclines me to think that this is some fringe-case WPF bug. As a side note, the Visual Studio WPF designer and XAML editor are giving me a problem with the following line: <PathGeometry Figures="{Binding Source={StaticResource TabSideFillFigures}}"/> Although WPF (at runtime) is perfectly happy binding Figures to the TabSideFillFigures string, with the Binding enforcing the use of the TypeConverter, the XAML editor and WPF designer are complaining. All the XAML code for the ControlTemplate is underlined and I get the following errors in the Error List: Error 9 '{DependencyProperty.UnsetValue}' is not a valid value for the 'System.Windows.Controls.Control.Template' property on a Setter. C:\Users\Alex\Documents\Visual Studio 2010\Projects\Ircsil\devel\Ircsil\MainWindow.xaml 1 1 Ircsil Error 10 Object reference not set to an instance of an object. C:\Users\Alex\Documents\Visual Studio 2010\Projects\Ircsil\devel\Ircsil\Skins\Default\MainSkin.xaml 58 17 Ircsil Again, to repeat, everything works perfectly well at runtime, which is what makes this particularly odd... Could someone perhaps shed some light on these issues, in particular the first (which seems to be a potential WPF bug), and the latter (which seems to be a Visual Studio bug). Any sort of feedback or suggestions would be much appreciated!

  • Partial string search in boost::multi_index_container

    - by user361699
    I have a struct to store info about persons and multi_index_contaider to store such objects struct person { std::string m_first_name; std::string m_last_name; std::string m_third_name; std::string m_address; std::string m_phone; person(); person(std::string f, std::string l, std::string t = "", std::string a = DEFAULT_ADDRESS, std::string p = DEFAULT_PHONE) : m_first_name(f), m_last_name(l), m_third_name(t), m_address(a), m_phone(p) {} }; typedef multi_index_container , ordered_non_unique, member, member persons_set; operator< and operator<< implementation for person bool operator<(const person &lhs, const person &rhs) { if(lhs.m_last_name == rhs.m_last_name) { if(lhs.m_first_name == rhs.m_first_name) return (lhs.m_third_name < rhs.m_third_name); return (lhs.m_first_name < rhs.m_first_name); } return (lhs.m_last_name < rhs.m_last_name); } std::ostream& operator<<(std::ostream &s, const person &rhs) { s << "Person's last name: " << rhs.m_last_name << std::endl; s << "Person's name: " << rhs.m_first_name << std::endl; if (!rhs.m_third_name.empty()) s << "Person's third name: " << rhs.m_third_name << std::endl; s << "Phone: " << rhs.m_phone << std::endl; s << "Address: " << rhs.m_address << std::endl; return s; } Add several persons into container: person ("Alex", "Johnson", "Somename"); person ("Alex", "Goodspeed"); person ("Petr", "Parker"); person ("Petr", "Goodspeed"); Now I want to find person by lastname (the first member of the second index in multi_index_container) persons_set::nth_index<1::type &names_index = my_set.get<1(); std::pair::type::const_iterator, persons_set::nth_index<1::type::const_iterator n_it = names_index.equal_range("Goodspeed"); std::copy(n_it.first ,n_it.second, std::ostream_iterator(std::cout)); It works great. Both 'Goodspeed' persons are found. Now lets try to find person by a part of a last name: std::pair::type::const_iterator, persons_set::nth_index<1::type::const_iterator n_it = names_index.equal_range("Good"); std::copy(n_it.first ,n_it.second, std::ostream_iterator(std::cout)); This returns nothing, but partial string search works as a charm in std::set. So I can't realize what's the problem. I only wraped strings by a struct. May be operator< implementation? Thanks in advance for any help.

This is very frustrating.... Thank you in advance.

  • How to setup a project to use TweetSharp

    - by Stuart Helwig
    I am trying to follow Pete Brown's introductory WPF tutorial which makes use of the TweetSharp libraries to interact with Twitter. I have downloaded what appears to be the latest TweetSharp binaries (and a few others including the ReleaseCandidate) from Codeplex (http://tweetsharp.codeplex.com/). No matter what references I add and no matter what using statements I try, I cannot create a reference to the TwitterService for the FluentTwitter class. I simply get the compiler error - "The type or namespace cannot be found". Now I've noticed that the TweetSharp.dll that Pete references is 518KB but the one contained in each of my different downloads is only 84kb. (I've tried several times - I am getting the full download here). The link from Pete's article to the TweetSharp libraries, no longer works (http://code.google.com/p/tweetsharp/). What basic element am I missing here or what could I be doing wrong?

  • Is it possible to use best_in_place with typeahead from twitter bootstrap?

    - by Dave H
    Basically, I am using best_in_place in my rails webapp to let users edit their profile info in place. The thing is, I would like users to be presented with a typeahead form for certain entries.. Here's what I'm working with: <p>College/University: <input type="text" class="span3" style="margin: 0 auto;" data-provide="typeahead" data-items="8" data-source='["University of Pennsylvania","Harvard","Yale","Princeton","Cornell","Brown","Columbia","Dartmouth"]'></p> This gives me a working form box with typeahead. However, I want to be able to wrap this in best_in_place with something like <%= best_in_place @student, :education %> so that users only see the typeahead form when they click on the text, and upon clicking away from the box or hitting enter the selection is stored in the database. Is there a reasonably easy way to do this?

Is this possible? I've been racking my brain and hitting the google but I can't find how and where to do this.

  • Why am I getting unexpected output trying to write a hash structure to a file?

    - by Harm De Weirdt
    I have a hash in which I store the products a customer buys (%orders). It uses the product code as key and has a reference to an array with the other info as value. At the end of the program, I have to rewrite the inventory to the updated version (i.e. subtract the quantity of the bought items) This is how I do rewrite the inventory: sub rewriteInventory{ open(FILE,'>inv.txt'); foreach $key(%inventory){ print FILE "$key\|$inventory{$key}[0]\|$inventory{$key}[1]\|$inventory{$key}[2]\n" } close(FILE); } where $inventory{$key}[x] is 0 → Title, 1 → price, 2 → quantity. The problem here is that when I look at inv.txt afterwards, I see things like this: CD-911|Lady Gaga - The Fame|15.99|21 ARRAY(0x145030c)||| BOOK-1453|The Da Vinci Code - Dan Brown|14.75|12 ARRAY(0x145bee4)||| Where do these ARRAY(0x145030c)||| entries come from? Or more important, how do I get rid of them?

  • When to use a module, and when to use a class

    - by Matt Briggs
    I am currently working through the Gregory Brown Ruby Best Practices book. Early on, he is talking about refactoring some functionality from helper methods on a related class, to some methods on module, then had the module extend self. Hadn't seen that before, after a quick google, found out that extend self on a module lets methods defined on the module see each other, which makes sense. Now, my question is when would you do something like this module StyleParser extend self def process(text) ... end def style_tag?(text) ... end end and then refer to it in tests with @parser = Prawn::Document::Text::StyleParser as opposed to just using a class with some class methods on it? is it so that you can use it as a mixin? or are there other reasons I'm not seeing?

  • What Java portal server do you use?

    I've been tasked with learning Vignette and setting it up is a nightmare. There are many different components in the wizard. If something fails, you get a cryptic error message and then have to start again. This is the worst "Wizard" since Kwame Brown. Are there other Portal servers out there that are easy to configure, or at least seem to have kept a developer's sanity in mind during configuration? To those that have used several different portal servers, which is your favorite?

  • NSString simple pattern matching

    - by SirRatty
    Hi all, Mac OS 10.6, Cocoa project, 10.4 compatibility required. (Please note: my knowledge of regex is quite slight) I need to parse NSStrings, for matching cases where the string contains an embedded tag, where the tag format is: [xxxx] Where xxxx are random characters. e.g. "The quick brown [foxy] fox likes sox". In the above case, I need to grab the string "foxy". (Or nil if no tag is found.) Each string will only have one tag, and the tag can appear anywhere within the string, or may not appear at all. Could someone please help with a way to do that, preferably without having to include another library such as RegexKit. Thank you for any help.

I can choose between breads.length and count.length I know it would be the same result, but I don't know which one I shoud choose. There are many other examples where I get the same problem. I'm sure that you have encountered this problem as well in the past. What should you choose? Are there general agreements? Thanks

  • SQL: How can i update a value on a column only if that value is null?

    - by user321185
    Hey, I have an SQL question which may be basic to some but is confusing me. Here is an example of column names for a table 'Person': PersonalID, FirstName, LastName, Car, HairColour, FavDrink, FavFood Let's say that I input the row: 121312, Rayna, Pieterson, BMW123d, Brown, NULL, NULL Now I want to update the values for this person, but only if the new value is not null, Update: 121312, Rayna, Pieterson, NULL, Blonde, Fanta, NULL The new row needs to be: 121312, Rayna, Pieterson, BMW123d, Blonde, Fanta, NULL So I was thinking something along the lines of: Update Person(PersonalID, FirstName, LastName, Car, HairColour, FavDrink, FavFood) set Car = @Car (where @Car is not null), HairColour = @HairColour (where @HairColour...)... etc. My only concern is that I can't group all the conditions at the end of the query because it will require all the values to have the same condition. Can't i do something like Update HairColour if @HairColour is not Null

  • Neural Network Inputs and Outputs to meaningful values

    - by Micheal
    I'm trying to determine how to transform my "meaningful input" into data for an Artificial Neural Network and how to turn the output into "meaningful output". The way I can always see of doing it is by convering everything to categories with binary values. For example, rather than outputting age, having a 0-1 for <10, a 0-1 for 10 - 19, etc. Same with the inputs, where I might be using for example, hair colour. Is the only way to turn this into input to have Blonde 0-1, Brown 0-1, etc? Am I missing some entire topic of ANNs? Most of the books and similar I read use theoretical examples.
