• Why do control keys (ctrl, shift, alt) not work sometimes?

  - by EricSchaefer

  Sometimes (about once a week) the control keys (ctrl, shift, alt) so not work anymore. They do work when I boot up, but after a while they stop working. Logging out and in again repairs it. What can cause something like that? Edit: It just happened again. Incidentally it happened right after vmware-player crashed just as the last time. Coincidence? Edit: It is a laptop keyboard (HP EliteBook 8730w) with german layout.

• How to redesign the UI of a large project?

  - by jem88

  I'm currently working at a quite big Android project (a social network, you can see it here if is useful to answer the question). We decided to restyle the whole app, changing all the UI design. The code I actually have is complex, there are many controllers, and it's a little messy too. Is it "better" in terms of time and code cleanliness to take one controller per time, and rewrite it entirely, or to modify one controller per time? The layout change entirely anyway, so for that I know I've to restart from scratch. Maybe it could seem a stupid question, but with the "time" variable I really can't see the best way.

• Is there a definitive reference on Pinball playfield design?

  - by World Engineer

  I'm looking at designing tables for Future Pinball but I'm not sure where to start as I've little background in game design per se. I've played scores of pinball tables over the years so I've a fairly good idea of what is "fun" in those terms. However, I'd like to know if there is a definitive "bible" of pinball design as far as layout and scoring/mode design goes. I've looked but there doesn't seem to be anything really coherent that I could find. Is it simply a lost art or am I missing some buried gem?

• How should I define my Java Objects?

  - by HonorGod

  I have a data grid where I sort of show the following information - All Guests Total Adults = 22 Total Children = 27 Confirmed Total Adults = 9 Total Children = 13 Country = Germany Total Adults = 5 Total Childres = 6 Friends Adults = 2 Children = 2 Relatives Adults = 3 Children = 4 Country = USA Total Adults = 4 Total Childres = 7 Friends Adults = 2 Children = 5 Relatives Adults = 2 Children = 2 Tentative Total Adults = 13 Total Children - 14 Country = Australia Total Adults = 7 Total Childres = 8 Friends Adults = 2 Children = 3 Relatives Adults = 5 Children = 5 Country = China Total Adults = 6 Total Childres = 6 Friends Adults = 2 Children = 4 Relatives Adults = 4 Children = 2 And in the database what I have is data at the lowest level which is Friends / Relatives and the corresponding countries set as a look-up value which in indirectly connected to another look-up that can tell me if they fall under confirmed or tentative. I guess my question is how do I layout my Java Object and perform the aggregations and give it back to the client. I am not sure if I am clear with my question, but feel free to comment so I can update the question accordingly.

• Photo sharing social platform [closed]

  - by user1696497

  I am working on a photo sharing social platform like Flickr, Photobucket. To start off with I have half a million photos as of now. I want to convert all of these into a single format, compression ratio and use it as an original image. I will be storing original image, re-sized image according to layout and a thumbnail. I have started off with ruby, didn't find supporting libraries. I am considering python as it has a good image processing library and instagram is using it. I want some advise about how the image has to be processed while uploading, efficient way of storage whether database or a file system, image compressions, and precautions to be taken. I would be having profile pictures, do I need store them separately or along with the images? If I want to store the images on a file system, which file system should I use and also should I store the url or should I use any intermediate key value store like redis?

• Network doesn't work after upgrading to 13.10

  - by Inkbug

  I upgraded from 13.04 to 13.10, and a number of things stopped working. Most importantly, I don't have internet access anymore. When I go to the network settings, I receive the following error: The system network services are not compatible with this version. The only settings that show up in the network settings are the proxy settings. I tried sudo service network-manager start and sudo service network-manager restart, but it told me the service was already running. In addition, the menu bar is missing all of the indicators (such as keyboard layout, sound, network, clock, and the gear icon). Is this related or a separate issue?

• How can I apply Readme Driven Development to an ongoing project?

  - by Metalcoder

  I'm assigned to a project where the goal is to update an existing software. This software was developed in a totally ad hoc manner, which means that any documentation generated is outdated, confused and just plain useless. I do not want to retroactivelly produce all the missing artifacts, since this would just be a waste of time. The code base is ugly, and really need some serious refactoring, but this is another story. What I want is to apply Readme Driven Development to guide this project. So, basically, I want to write a Readme, which will document every change meaningful at the user level. The problem is, I have no idea about how to structure this document. For me, it's pretty clear that it should have a different layout than the traditional Readme. I really want to document changes, and not the current state of affairs. Any ideas?

• Desktop GUI Client - Remote RDBMS communication

  - by magom001

  Sorry if I am asking a trivial question but I have been searching for a while without any luck. I need to design a system and I am looking for advice on the technology that should be used. The layout is very simple: it is a sales application with a centralized database and multiple clients. Each salesperson has GUI app installed on his/her laptop that should be able to connect to the database to retrieve data and upload data (i.e. register new orders). My question is the following: how should the communication between the client and the server be implemented? I doubt that connecting directly to the RDBMS is a good idea... Should I use web-services? XML-RPC? How to implement authentication and encode the data? Thanks for your advice!

• Facebook likes reset after moving to HTTPS

  - by aarondicks

  I've got a question regarding the Facebook like button. We worked on a piece recently that embeds a number of social share buttons (please see the source code below). When the piece was released, it was on HTTP, and received over 2k likes (the URL 'slug' hasn't changed at all). The site was recently migrated to permanent-on HTTPS, and the like data has been reset, and we've been left with 50 new, recent likes. If you see in the source code, the URL is set explicitly to like the HTTP version, which I believe to be correct. Can anyone help me work out what's happened here? Here's the HTML bit of the like button: <div class="fb-like" data-href="http://www.harveywatersofteners.co.uk/history-interior-design" data-layout="box_count" data-action="like" data-show-faces="false" data-share="false"></div>

• Connect divs with (non-straight) lines [migrated]

  - by Snailer

  I'd like to develop my site with a layout that looks somewhat like houses with connected plumbing, or multiple computers connected to a network. Basically, the will be boxes floating in space, with lines connecting some of the boxes. I'd like these lines to have some turns in them as well (just simple 90 degree corners) rather than just a straight line. My question is what is the best way to achieve this, and perhaps a small example. My thoughts were to use: PHP and CSS: I could create a background grid and then, with some complicated algorithms, draw paths using the grid's borders. This would be more dynamic, but I'm not sure I can plot the math all by myself. just CSS: Perhaps this is as simple as making some pre-drawn lines like L-shapes and T-junctions, then just placing and scaling them. But I don't believe there's a way to scale an image by slicing it.. so the line width would be scaled and thus each image would look different. Any thoughts?

• WordPress for Windows Phone 7

  - by Enrique Lima

  Slowly but surely apps have been coming out for Windows Phone 7, I must admit that was my biggest concern on moving from the iPhone to the Windows Phone.  Not the fact apps would come slowly, but when they would come.  The iPhone side of things had very nice apps, and moving into a not so populated app landscape was an interesting thought. Anyway, yes there are apps I miss … but now it is one less! WordPress released the “for Windows Phone 7” app. Great experience and layout for the tool. If you are now on Windows Phone 7, check it out. http://windowsphone.wordpress.org/

• How can I prevent my site from being branded a "content farm?"

  - by Fredashay

  I'm building a small social Q&A site. Another Q&A site that I use was recently branded by Google as a content farm and removed from Google results. I know what Wikipedia says is the definition of a content farm (low quality paid articles and spammy text across the page to catch search engines). That other site I use doesn't do those things, so there must be more to it than that. I want to make sure I don't do anything that causes Google to think my Q&A site is a content farm. What should I do, or avoid doing in designing my site layout?

• Is asking for control totals on a file an outdated means of verifying a file?

  - by CTKeane

  I'm in a new position where I need to process a flat files on a regular basis. The last time I did this was 5 or 6 years ago but as part of the file layout I received control totals. It gave me simplistic information on the file like the total number of records as well as sums of the important fields. This helped me during testing then also during production to verify the file arrived and has correct information. I have asked for similar data for this new project and have hit a wall of no. Is this no longer a standard practice? Is there a better way?

• Testing complex compositions

  - by phlipsy

  I have a rather large collection of classes which check and mutate a given data structure. They can be composed via the composition pattern into arbitrarily complex tree-like structures. The final product contains a lot of these composed structures. My question is now: How can I test those? Albeit it is easy to test every single unit of these compositions, it is rather expensive to test the whole compositions in the following sense: Testing the correct layout of the composition-tree results in a huge number of test cases Changes in the compositions result in a very laborious review of every single test case What is the general guideline here?

• Wine 1.6.2-Trying to switch to 32-bit Wineprefix from 64-bit Wine (Trusty 14.04). Can anyone help me out?

  - by AlternateSteve90

  Hello fellow Ubuntu users, I'm having a little trouble with Wine 1.6.1 and I was wondering if someone could help me out. I recently downloaded some 32-bit games that I'd wanted to try(BeamNG Drive and Bugbear's Next Car Game demo) and I had run into some trouble trying to get either of these games to run. So I came across a couple pieces of advice on the 'Net, one here on the Ubuntu community site and the other at BeamNG's forums, on how to create a 32-bit wineprefix on a 64-bit setup. I managed to be able to create the wine32 folder, but now I'm having trouble making it my default Wine setup. Anybody have any idea how I can do that? I'll post the URLs for said advice, btw: http://www.beamng.com/threads/1788-Installing-DRIVE-under-Linux-via-Wine How do I create a 32-bit WINE prefix? Here's what I've tried so far in the Terminal: steven@steven-HP-Pavilion-17-Notebook-PC:~$ WINEPREFIX='/home/user/wine32' WINEARCH='win32' wine 'wineboot' wine: chdir to /home/user/wine32 : No such file or directory steven@steven-HP-Pavilion-17-Notebook-PC:~$ WINEPREFIX='/home/steven/wine32' WINEARCH='win32' wine 'wineboot' wine: created the configuration directory '/home/steven/wine32' fixme:storage:create_storagefile Storage share mode not implemented. err:mscoree:LoadLibraryShim error reading registry key for installroot err:mscoree:LoadLibraryShim error reading registry key for installroot err:mscoree:LoadLibraryShim error reading registry key for installroot err:mscoree:LoadLibraryShim error reading registry key for installroot fixme:storage:create_storagefile Storage share mode not implemented. fixme:iphlpapi:NotifyAddrChange (Handle 0x10ee890, overlapped 0x10ee89c): stub wine: configuration in '/home/steven/wine32' has been updated. steven@steven-HP-Pavilion-17-Notebook-PC:~$ WINEPREFIX=$HOME/.wine32 wine dxsetup.exe wine: created the configuration directory '/home/steven/.wine32' fixme:storage:create_storagefile Storage share mode not implemented. err:mscoree:LoadLibraryShim error reading registry key for installroot err:mscoree:LoadLibraryShim error reading registry key for installroot err:mscoree:LoadLibraryShim error reading registry key for installroot err:mscoree:LoadLibraryShim error reading registry key for installroot fixme:storage:create_storagefile Storage share mode not implemented. fixme:iphlpapi:NotifyAddrChange (Handle 0x103e2b8, overlapped 0x103e2d0): stub fixme:storage:create_storagefile Storage share mode not implemented. fixme:iphlpapi:NotifyAddrChange (Handle 0x10fe890, overlapped 0x10fe89c): stub wine: configuration in '/home/steven/.wine32' has been updated. wine: cannot find L"C:\windows\system32\dxsetup.exe" steven@steven-HP-Pavilion-17-Notebook-PC:~$ WINEARCH=win64 winecfgsteven@steven-HP-Pavilion-17-Notebook-PC:~$ WINEPREFIX='/home/steven/wine32' WINEARCH='win32' wine 'wineboot' steven@steven-HP-Pavilion-17-Notebook-PC:~$ WINEARCH=win32 winecfg wine: WINEARCH set to win32 but '/home/steven/.wine' is a 64-bit installation. steven@steven-HP-Pavilion-17-Notebook-PC:~$ WINEPREFIX='/home/steven/wine32' WINEARCH='win32' wine 'wineboot' steven@steven-HP-Pavilion-17-Notebook-PC:~$ WINEPREFIX='/home/user/wine32' WINEARCH='win32' wine 'wineboot' wine: chdir to /home/user/wine32 : No such file or directory steven@steven-HP-Pavilion-17-Notebook-PC:~$ WINEPREFIX='/home/steven/wine32' WINEARCH='win32' wine 'wineboot' steven@steven-HP-Pavilion-17-Notebook-PC:~$ WINEPREFIX=/home/steven/wine32 WINEARCH='win32' wine 'wineboot' steven@steven-HP-Pavilion-17-Notebook-PC:~$ WINEPREFIX=/home/steven/wine32 WINEARCH=win32 wine wineboot steven@steven-HP-Pavilion-17-Notebook-PC:~$ So, yeah.

• What is Agile Modeling and why do I need it?

  What is Agile Modeling and why do I need it? Agile Modeling is an add-on to existing agile methodologies like Extreme programming (XP) and Rational Unified Process (RUP). Agile Modeling enables developers to develop a customized software development process that actually meets their current development needs and is flexible enough to adjust in the future. According to Scott Ambler, Agile Modeling consists of five core values that enable this methodology to be effective and light weight Agile Modeling Core Values: Communication Simplicity Feedback Courage Humility Communication is a key component to any successful project. Open communication between stakeholder and the development team is essential when developing new applications or maintaining legacy systems. Agile models promote communication amongst software development teams and stakeholders. Furthermore, Agile Models provide a common understanding of an application for members of a software development team allowing them to have a universal common point of reference. The use of simplicity in Agile Models enables the exploration of new ideas and concepts through the use of basic diagrams instead of investing the time in writing tens or hundreds of lines of code. Feedback in regards to application development is essential. Feedback allows a development team to confirm that the development path is on track. Agile Models allow for quick feedback from shareholders because minimal to no technical expertise is required to understand basic models. Courage is important because you need to make important decisions and be able to change direction by either discarding or refactoring your work when some of your decisions prove inadequate, according to Scott Ambler. As a member of a development team, we must admit that we do not know everything even though some of us think we do. This is where humility comes in to play. Everyone is a knowledge expert in their own specific domain. If you need help with your finances then you would consult an accountant. If you have a problem or are in need of help with a topic why would someone not consult with a subject expert? An effective approach is to assume that everyone involved with your project has equal value and therefore should be treated with respect. Agile Model Characteristics: Purposeful Understandable Sufficiently Accurate Sufficiently Consistent Sufficiently Detailed Provide Positive Value Simple as Possible Just Fulfill Basic Requirements According to Scott Ambler, Agile models are the most effective possible because the time that is invested in the model is just enough effort to complete the job. Furthermore, if a model isn’t good enough yet then additional effort can be invested to get more value out of the model. However if a model is good enough, for the current needs, or surpass the current needs, then any additional work done on the model would be a waste. It is important to remember that good enough is in the eye of the beholder, so this can be tough. In order for Agile Models to work effectively Active Stakeholder need to participation in the modeling process. Finally it is also very important to model with others, this allows for additionally input ensuring that all the shareholders needs are reflected in the models. How can Agile Models be incorporated in to our projects? Agile Models can be incorporated in to our project during the requirement gathering and design phases. As requirements are gathered the models should be updated to incorporate the new project details as they are defined and updated. Additionally, the Agile Models created during the requirement phase can be the bases for the models created during the design phase.  It is important to only add to the model when the changes fit within the agile model characteristics and they do not over complicate the design.

• jQuery Context Menu Plugin and Capturing Right-Click

  - by Ben Griswold

  I was thrilled to find Cory LaViska’s jQuery Context Menu Plugin a few months ago. In very little time, I was able to integrate the context menu with the jQuery Treeview.  I quickly had a really pretty user interface which took full advantage of limited real estate.  And guess what.  As promised, the plugin worked in Chrome, Safari 3, IE 6/7/8, Firefox 2/3 and Opera 9.5.  Everything was perfect and I shipped to the Integration Environment. One thing kept bugging though – right clicks aren’t the standard in a web environment. Sure, when one hovers over the treeview node, the mouse changed from an arrow to a pointer, but without help text most users will certainly left-click rather than right. As I was already doubting the design decision, we did some Mac testing.  The context menu worked in Firefox but not Safari.  Damn.  That’s when I started digging into the Madness of Javascript Mouse Events.  Don’t tell, but it’s complicated.  About as close as one can get to capture the right-click mouse event on all major browsers on Windows and Mac is this: if (event.which == null) /* IE case */ button= (event.button < 2) ? "LEFT" : ((event.button == 4) ? "MIDDLE" : "RIGHT"); else /* All others */ button= (event.which < 2) ? "LEFT" : ((event.which == 2) ? "MIDDLE" : "RIGHT"); Yikes.  The content menu code was simply checking if event.button == 2.  No problem.  Cory offers a jQuery Right Click Plugin which I’m sure works for windows but probably not the Mac either.  (Please note I haven’t verified this.) Anyway, I decided to address my UI design concern and the Safari Mac issue in one swoop.  I decided to make the context menu respond to any mouse click event.  This didn’t take much – especially after seeing how Bill Beckelman updated the library to recognize the left click. First, I added an AnyClick option to the library defaults: // Any click may trigger the dropdown and that's okay // See Javascript Madness: Mouse Events – http: //unixpapa.com/js/mouse.html if (o.anyClick == undefined) o.anyClick = false; And then I trigger the context menu dropdown based on the following conditional: if (evt.button == 2 || o.anyClick) { Nothing tricky about that, right?  Finally, I updated my menu setup to include the AnyClick value, if true: $('.member').contextMenu({ menu: 'memberContextMenu', anyClick: true },             function (action, el, pos) {                 … Now the context menu works in “all” environments if you left, right or even middle click.  Download jQuery Context Menu Plugin for Any Click *Opera 9.5 has an option to allow scripts to detect right-clicks, but it is disabled by default. Furthermore, Opera still doesn’t allow JavaScript to disable the browser’s default context menu which causes a usability conflict.

Suboptimal Thinking within Enterprise Architecture | James McGovern McGovern says: "We need to remember that enterprises live and thrive beyond just the current person at the helm." Boundaryless Information Flow | Richard Veryard "If all the boundaries are removed or porous, then the (extended) enterprise or ecosystem becomes like a giant sponge, in which all information permeates the whole," Veryard says.

• Your Job Search Should be More Than Just a New Year's Resolution

  - by david.talamelli

  I love the beginning of a new year, it is a great chance to refocus and either re-evaluate goals you are working to or even set new ones. I don't have any statistics to measure this but I am sure that one of the more popular new year's resolutions in the general workforce is to either get a new job or work to further develop one's career. I think this is a good idea, in today's competitive work force people should have a plan of what they want to do, what role they are after and how to get there. One common mistake I think many people make though is that a career plan shouldn't be a once a year thought. When people finish with the holiday season with their new year's resolution to find a new job fresh in their mind, you can see the enthusiasm and motivation a person has to make something happen. Emails are sent, calls are made, applications are made, networking is happening, etc..... Finding the right role that you are after however can be difficult, while it would be great if that dream role was available just at the time you happened to be looking for it - in reality this is not always the case. Job Seekers need to keep reminding themselves that while sometimes that dream job they are after is available at the same time they are looking, that also a Job search can be a difficult and long process. Many people who set out with the best of intentions in January to find a new job can soon lose interest in a job search if they do not immediately find a role. Just like the Christmas decorations are put away and the photos from New Year's are stored away - a Job Seeker's motivation may slowly decrease until that person finds themselves 12 months later in the same situation in same role and looking for that new opportunity again. Rather than just "going for it" and looking for a role in the month of January, a person's job search or career plan should be an ongoing activity and thought process that is constantly updated and evaluated over the course of the year. It can be hard to stay motivated over an extended period of time, especially when you are newly motivated and ready for that new role and the results are not immediate. Rather than letting your job search fall down the priority list and into the "too hard basket" a few ideas that may keep your enthusiasm fresh Update your resume every 6 months, even if you are not looking for a job - it is easy to forget what you have accomplished if you don't keep your details updated. Also it is good to be prepared and have a resume ready to go in case you do get an unexpected phone call for that 'dream job' you have been hoping for. Work out what you want out of your next role before you begin your job search - rather than aimlessly searching job ads or talking to people - think of the organisations or type of role you would like before you search. If you know what you are looking for it will be much easier to work out how to get there than if you do not know what you want. Don't expect immediate results once you decide to look for another job, things don't always fall into place. Timing and delivery can be important pieces of being selected for a role, companies don't hire every role in January. Have an open mind - people you meet or talk to may not result in immediate results for your job search but every connection may help you get a bit closer to what you are after . These actions will not guarantee a positive result, but in today's competitive work force every little of extra preparation and planning helps. All the best for 2011 and I hope your career plan whatever it may be is a success.

• July, the 31 Days of SQL Server DMO’s – Day 23 (sys.dm_db_index_usage_stats)

  - by Tamarick Hill

  The sys.dm_db_index_usage_stats Dynamic Management View is used to return usage information about the various indexes on your SQL Server instance. Let’s have a look at this DMV against our AdventureWorks2012 database so we can examine the information returned. SELECT * FROM sys.dm_db_index_usage_stats WHERE database_id = db_id('AdventureWorks2012') The first three columns in the result set represent the database_id, object_id, and index_id of a given row. You can join these columns back to other system tables to extract the actual database, object, and index names. The next four columns are probably the most beneficial columns within this DMV. First, the user_seeks column represents the number of times that a user query caused a seek operation against a particular index. The user_scans column represents how many times a user query caused a scan operation on a particular index. The user_lookups column represents how many times an index was used to perform a lookup operation. The user_updates column refers to how many times an index had to be updated due to a write operation that effected a particular index. The last_user_seek, last_user_scan, last_user_lookup, and last_user_update columns provide you with DATETIME information about when the last user scan, seek, lookup, or update operation was performed. The remaining columns in the result set are the same as the ones we previously discussed, except instead of the various operations being generated from user requests, they are generated from system background requests. This is an extremely useful DMV and one of my favorites when it comes to Index Maintenance. As we all know, indexes are extremely beneficial with improving the performance of your read operations. But indexes do have a downside as well. Indexes slow down the performance of your write operations, and they also require additional resources for storage. For this reason, in my opinion, it is important to regularly analyze the indexes on your system to make sure the indexes you have are being used efficiently. My AdventureWorks2012 database is only used for demonstrating or testing things, so I dont have a lot of meaningful information here, but for a Production system, if you see an index that is never getting any seeks, scans, or lookups, but is constantly getting a ton of updates, it more than likely would be a good candidate for you to consider removing. You would not be getting much benefit from the index, but yet it is incurring a cost on your system due to it constantly having to be updated for your write operations, not to mention the additional storage it is consuming. You should regularly analyze your indexes to ensure you keep your database systems as efficient and lean as possible. One thing to note is that these DMV statistics are reset every time SQL Server is restarted. Therefore it would not be a wise idea to make decisions about removing indexes after a Server Reboot or a cluster roll. If you restart your SQL Server instances frequently, for example if you schedule weekly/monthly cluster rolls, then you may not capture indexes that are being used for weekly/monthly reports that run for business users. And if you remove them, you may have some upset people at your desk on Monday morning. If you would like to begin analyzing your indexes to possibly remove the ones that your system is not using, I would recommend building a process to load this DMV information into a table on scheduled basis, depending on how frequently you perform an operation that would reset these statistics, then you can analyze the data over a period of time to get a more accurate view of what indexes are really being used and which ones or not. For more information about this DMV, please see the below Books Online link: http://msdn.microsoft.com/en-us/library/ms188755.aspx Follow me on Twitter @PrimeTimeDBA

• Create a Search Filter List in Google Chrome

  - by Asian Angel

  Are you tired of unwanted and/or non-relevant results cluttering up the search results at Bing, Yahoo, and Google? With the Search Filter extension for Chrome you can easily remove the unwanted “chaff” from your search results. Note: The extension only works on Bing, Yahoo, and Google at this time. Before For our example we conducted a search for “anime wallpapers” at Yahoo Singapore, Bing Singapore, and Google. In each set of results we decided to focus on results that would display either a yellow or red warning color from WOT. You can see our targeted result for Yahoo Singapore… The one for Bing Singapore… And the targeted result from Google. Search Filter in Action As soon as you install the extension you should take a quick look at the “Options”. At first the “Filters List Area” will be empty but will not remain so for long as you create your own filter list. The second part may or may not be of interest to you…the ability to opt into the filter service. If you opt in your filter list will be connected to your “Google Account” and will be available on any of your Chrome installs with the extension installed (and set to “Opt In”). Keep in mind that if you choose this option the filter list that you create will be aggregated anonymously and have a GUID number attached to it. After installing the extension we refreshed each of our three search pages…notice the small red circle button beside each search result link. Clicking on the red circle button will cause the entire browser window area to “shade out” temporarily while you decide between adding that website to the filter list or cancelling the action. If you add a website to the filter list that result will immediately disappear from the search results list without refreshing the webpage. Looks like we have another website at the bottom that we could add to the filter list… Click, click, click! After adding one website from each of the three search services you can see that our filter list has gotten off to a nice start. If for some reason you accidentally add a website to the list or change your mind about a website simply click on the red circle button to remove that particular listing. Conclusion If you are looking for an easy way to create a search filter list then this is definitely an extension that is worth taking the time to look at.

• Ubuntu-one syncs single files, but not directories [closed]

  - by Luiz Cláudio Duarte

  I'm using Ubuntu 10.10, fully updated. I have tried to sync my ~/Documents and ~/Pictures folders; U1 replicates the directory structure, but no files are uploaded. Next I tried to sync a single file inside ~/Ubuntu One and it was synced. Then I tried to put a directory inside ~/Ubuntu One and, again, the directory structure was replicated, but no files were synced. All the files have the "syncing" icon, however. The latest syncdaemon.log is below: 2011-03-30 07:41:50,752 - ubuntuone.SyncDaemon.fsm - INFO - loading updated metadata 2011-03-30 07:41:55,081 - ubuntuone.SyncDaemon.fsm - INFO - initialized: idx_path: 266, idx_node_id: 266, shares: 1 2011-03-30 07:41:55,082 - ubuntuone.SyncDaemon.GeneralINotProc - INFO - Ignoring files: ['\\A#.*\\Z', '\\A.*~\\Z', '\\A.*\\.py[oc]\\Z', '\\A.*\\.sw[nopx]\\Z', '\\A.*\\.swpx\\Z', '\\A\\..*\\.tmp\\Z'] 2011-03-30 07:41:55,083 - ubuntuone.SyncDaemon.HQ - INFO - HashQueue: _hasher started 2011-03-30 07:41:55,902 - ubuntuone.SyncDaemon.DBus - INFO - DBusInterface initialized. 2011-03-30 07:41:55,903 - ubuntuone.SyncDaemon.Main - INFO - Using '/home/l_claudius/Ubuntu One' as root dir 2011-03-30 07:41:55,903 - ubuntuone.SyncDaemon.Main - INFO - Using '/home/l_claudius/.local/share/ubuntuone/syncdaemon' as data dir 2011-03-30 07:41:55,903 - ubuntuone.SyncDaemon.Main - INFO - Using '/home/l_claudius/.local/share/ubuntuone/shares' as shares root dir 2011-03-30 07:41:55,903 - ubuntuone.SyncDaemon.Main - NOTE - ---- MARK (state: <State: 'INIT' (queues IDLE connection 'Not User Not Network')>; queues: metadata: 0; content: 0; hash: 0, fsm-cache: hit=1 miss=266) ---- 2011-03-30 07:41:55,904 - ubuntuone.SyncDaemon.Main - NOTE - Local rescan starting... 2011-03-30 07:41:55,904 - ubuntuone.SyncDaemon.local_rescan - INFO - start scan all volumes 2011-03-30 07:41:55,906 - ubuntuone.SyncDaemon.local_rescan - INFO - processing trash 2011-03-30 07:41:56,044 - ubuntuone.SyncDaemon.local_rescan - INFO - processing move limbo 2011-03-30 07:41:56,491 - ubuntuone.SyncDaemon.Main - NOTE - Local rescan finished! 2011-03-30 07:41:56,492 - ubuntuone.SyncDaemon.Main - INFO - hash queue empty.
