• How to copy windows explorer file selections and past filenames as txt

  - by Ricky Williams

  Win7 How can I select multiple files in explorer and get a string of text listing the file names like i would get if i selected the files from within "open file" window of an application. for example if i have a Dir that contains 100 jpegs and i select 01.jpg, 05.jpg, 10.jpg in windows explore via ctrl+clicks or shift+click how can i get a text string that reads " "01.jpg" "05.jpg" "10.jpg" with or without the selected files full path " with out dragging the selected files to another window? I've tried copy and pasting into Note Pad and Word Pad and it either past the picts into the the application or a empty clipboard.

• How do I install the vi text editor ONLY on my Cygwin installation?

  - by gath

  I have managed to install the Cygwin on my Windows Vista machine. I installed using the default settings. When I try to do vi in the Bash shell, Bash tells me command not found. I believe I need to install the Cygwin editors package which include the vi editor. The nightmare is every time I run the Cygwin setup and select ONLY the editors package and specifically the Vim and select install, Cygwin setup tries to install all other packages, very frustrating!! Is there an easier way of installing just a single package using the Cygwin setup utility?

• Dual boot UEFI Windows 7 and Ubuntu 12.04 (both 64 bits). W7 entry doesn't appear in GRUB

  - by Joe

  After trying to install both OS during 2 days, I'm confused and getting mad... I have SSD 128 GB and HDD 500 GB both empty. My laptop is Asus K55VM. BIOS support UEFI. What I have done: Install new SSD (Samsung 830 128GB) Use GParted on liveCD to create new table of partitions (GPT) and create 3 partitions (in the SSD) for different purposes: Partition 1: 80 GB (w7); Partition 2: 30 GB (Ubuntu 12.04 -Just / -); Partition 3: 10 GB unused (for future extesion of the other partitions) Install Windows 7 (with UEFI) in Partition 1. This create: /dev/sda1 - 100 MB for System (UEFI boot I guess) - FAT32 /dev/sda2 - 100 MB aprox. for MSR /dev/sda3 - 79.800 MB aprox. for Windows7 data In this point everything works fine. I have W7. Now I install Ubuntu 12.04 amd64 (with UEFI) as follows: Install / in Partition 2 - /dev/sda4 30 GB ext4, and in the hdd I install /home and swap. I select bootloader in /dev/sda1 (where it's supposed to be the UEFI boot). I install updates and reboot. Problem: Now just appears grub menu with Ubuntu entries and not Windows 7. Alternative solution found: When I turn on laptop, before loading GRUB I press ESC key and appear BIOS boot, so I can select to boot the Windows partition, Ubuntu partition, DVD, USB, etc... but I think is not the best way to boot different OS. I've tried: sudo update-grub2 with no success. What can I do??

• Vaadin Calendar events not shown if overnight [migrated]

  - by B_B

  In my vaadin project there is the possibility to create events that are shown by the calendar. It does works, except when the event is overnight, let's say the night from 23th to 24th, and the calendar shows as only day the 24th. In this case the part of the event that belongs to the 24th is supposed to be shown, but it is not. When I switch to weekly view, the event is shown properly. Here is the function where I get the data and use a container for the calendar: /* Fill Calendar from database */ void updateData() { final BeanItemContainer<TypeReservationEvent> container = new BeanItemContainer<TypeReservationEvent>(TypeReservationEvent.class); Map<String, Object> parameters = new HashMap<String, Object>(); parameters.put("roomParent",chosenRoom); String query = "SELECT DISTINCT res FROM EntityReservation res, EntityRoom r, EntityTable rt WHERE res.tableId = rt.id " + "AND rt.roomParent =:roomParent"; reservationList = facade.list(query, parameters); for(EntityReservation rt : reservationList) { container.addBean(new TypeReservationEvent(rt)); } container.sort(new Object[]{"start"}, new boolean[]{true}); cal.setContainerDataSource(container, "caption", "description", "start", "end", "styleName"); // Force calendar to refresh if(selectCalViewType.getValue() == chooseWeeklyView) { setViewType(calViewType.DAILY); setViewType(calViewType.WEEKLY); } else if (selectCalViewType.getValue() == chooseDailyView) { setViewType(calViewType.WEEKLY); setViewType(calViewType.DAILY); } } TIA

• Route global shortcuts to pages opened in Firefox

  - by zamza

  I like listening to music online on sites like stereomood.com. There is a major problem, however. I can not control the player with my keyboard. And even with a mouse - when I want to play/pause I must activate firefox window, select the tab where music plays and hit play/pause button manually - this is a pain, especially when you play a fullscreen game that can not minimize itself. Thus said, global keyboard shortcuts would be a perfect solution. I understand that different online media players have different controls and each site must be configured individually (like, select button with id 'play' and press it), but I believe that can be done in principle. I also guess that such tricks are impossible without some third-party native app which captures shortcuts and routes them to Firefox window. So, any solutions? Maybe some AutoHotkey hacks or similar.

• table alias (or 'symlink') in mysql

  - by andreash

  Hi there, in MySQL5.1, is there a way to make one table accessible by two different names? I'm thinking about somethink like a symlink on linux filesystems. I know theres the CREATE VIEW myview AS SELECT * FrOM mytable thing, but I don't only need to SELECT from both names, but also delete etc ... You might ask why I want to do this? It's about getting a commercial, closed-source app to work, which is crappily programmed (usually, the table names are all lower-case, but occasionally, they use capitalized names for the same table ...). Oh, that would be another idea: Is there a way to tell MySQL not to care about capitalization of table names (like on Windows filesystems?)? that would also do the trick ... Thanks for your insight! A.

• Change the Log Level of Node Manager.

  - by adejuanc

  This is useful to troubleshoot issues related to Node Manager, such as problems starting a Managed Server or reasons a server could be (re)started. To change the Log Level of Node Manager, you need to edit the nodemanager.properties file. This is usually located at: <MIDDLEWARE_HOME>/wlserver_10.3/common/nodemanager What you need to modify is property: ...LogLevel=INFO... Information about the appropriate values for this property is available in the Node Manager Documentation at 10.3 WebLogic Documentation (and in further releases) which states: LogLevel: Severity level of logging used for the Node Manager log. Node Manager uses the same logging levels as WebLogic Server. Default value: INFO However, this is incorrect. WLS has its own implementation of LogLevel, but Node Manager uses the standard Log Level from the java.util.logging.Level class. Therefore, the possible values for Node Manager LogLevel, in descending order are: SEVERE (highest value) WARNING INFO CONFIG FINE FINER FINEST (lowest value) The highest value provides only messages at the severe level. The warning level provides warning messages and severe messages, and so on. Besides those levels, ALL and OFF are also accepted. For example, if you only want Severe messages to be logged, select SEVERE. If you need the most detailed tracing available, select FINEST. For more information on what it will log at each level, please read the Java SE API for LoggingLevel.

• Using Queries with Coherence Read-Through Caches

  - by jpurdy

  Applications that rely on partial caches of databases, and use read-through to maintain those caches, have some trade-offs if queries are required. Coherence does not support push-down queries, so queries will apply only to data that currently exists in the cache. This is technically consistent with "read committed" semantics, but the potential absence of data may make the results so unintuitive as to be useless for most use cases (depending on how much of the database is held in cache). Alternatively, the application itself may manually "push down" queries to the database, either retrieving results equivalent to querying the cache directly, or may query the database for a key set and read the values from the cache (relying on read-through to handle any missing values). Obviously, if the result set is too large, reading through the cache may cause significant thrashing. It's also worth pointing out that if the cache is asynchronously synchronized with the database (perhaps via database change listener), that an application may commit a transaction to the database, then generate a key set from the database via a query, then read cache entries through the cache, possibly resulting in a race condition where the application sees older data than it had previously committed. In theory this is not problematic but in practice it is very unintuitive. For this reason it often makes sense to invalidate the cache when updating the database, forcing the next read-through to update the cache.

• How to tell if any MySQL connections has been dropped or timed out?

  - by Continuation

  A client is using PHP to connect to MySQL. The PHP scripts and the MySQL database are located on 2 different Linux servers. He complained that database connections were being dropped or timed out and asked me to take a look. Is there any place in MySQL that can show me what and how many connections have been dropped or timed out? I looked into slow query log and didn't see anything. Any suggestions on how to diagnose this dropped/timed out database connection problem? Thanks EDIT: Slow query log is enabled in my.cnf: log-slow-queries=/var/log/mysql-slow-queries.log And when I do a mysql> show global status; I got: | Slow_queries | 11402347 | So there are a lot of slow queries. But the file /var/log/mysql-slow-queries.log doesn't exist. Why is that?

• Structuring Access Control In Hierarchical Object Graph

  - by SB2055

  I have a Folder entity that can be Moderated by users. Folders can contain other folders. So I may have a structure like this: Folder 1 Folder 2 Folder 3 Folder 4 I have to decide how to implement Moderation for this entity. I've come up with two options: Option 1 When the user is given moderation privileges to Folder 1, define a moderator relationship between Folder 1 and User 1. No other relationships are added to the db. To determine if the user can moderate Folder 3, I check and see if User 1 is the moderator of any parent folders. This seems to alleviate some of the complexity of handling updates / moved entities / additions under Folder 1 after the relationship has been defined, and reverting the relationship means I only have to deal with one entity. Option 2 When the user is given moderation privileges to Folder 1, define a new relationship between User 1 and Folder 1, and all child entities down to the grandest of grandchildren when the relationship is created, and if it's ever removed, iterate back down the graph to remove the relationship. If I add something under Folder 2 after this relationship has been made, I just copy all Moderators into the new Entity. But when I need to show only the top-level Folders that a user is Moderating, I need to query all folders that have a parent folder that the user does not moderate, as opposed to option 1, where I just query any items that the user is moderating. Thoughts I think it comes down to determining if users will be querying for all parent items more than they'll be querying child items... if so, then option 1 seems better. But I'm not sure. Is either approach better than the other? Why? Or is there another approach that's better than both? I'm using Entity Framework in case it matters.

• tmux -- any way to enable scrolling, but not selection?

  - by gatoatigrado

  I like that when mode-mouse is on in tmux, I can scroll through the buffer, but I don't like that I can't copy stuff to my OS clipboard by selecting it (as when tmux is disabled). Question: Is there any way to enable mouse scrolling, but not selection? I'm using KDE's konsole, if it matters. I've tried setting, set -g mouse-select-pane off set -g mouse-select-window off but no luck -- the only difference seems to be whether mode-mouse is on (tmux captures scrolling and selection) or off (tmux captures neither scrolling nor selection).

• ubuntu 12.04 installer does not recognize drive partitions

  - by endless forms

  I recently purchased a new HP Pavilion HPE desktop running Windows 7. I am trying to install a dual-boot system with 12.04. However, when I run the LiveCD I only get as far as the "Install" window where you can select the partitions for your drives. On the bottom where it says "device for boot loader installation" I have "/dev/sda" and cannot select any other devices. All the options to change the drives are greyed out, most likely because there are no drives in the window. I partitioned my largest drive using the tools within Windows, then booted into the CD, but nothing shows up. I then used Gparted to change the new space from unallocated to an /ext2, and still nothing shows up. The installer does not recognize anything, but when I go into an Ubuntu session and use the disk utility manager I can see the partitions I made. Anything I do has to be done outside of the installer. I have no files on this new computer, so this is the perfect time to install a parallel OS. I would like avoid completely reinstalling Windows, however. I've been over the forums many times, but all the answers I've found have not worked for me. I also tried flagging the new, empty partition as boot, but that screwed Windows up. Also, the WUBI installer hits the same point and quits. I know that the disk itself is fine because I just made another dual boot system on a Gateway PC. This makes me think something within this computer is preventing the installer from "seeing" the drives. Any help would be much appreciated! Edit in response: The main part of the partitioning window shows no partitions, everything is blank. There is no way to add partitions, and all the buttons are useless. I've tried defragging my drive multiple times, and I also used the same disk to dual-boot another PC with no problems, so it's not the disk, it's definitely the computer.

• How to quickly search through a very large list of strings / records on a database

  - by Giorgio

  I have the following problem: I have a database containing more than 2 million records. Each record has a string field X and I want to display a list of records for which field X contains a certain string. Each record is about 500 bytes in size. To make it more concrete: in the GUI of my application I have a text field where I can enter a string. Above the text field I have a table displaying the (first N, e.g. 100) records that match the string in the text field. When I type or delete one character in the text field, the table content must be updated on the fly. I wonder if there is an efficient way of doing this using appropriate index structures and / or caching. As explained above, I only want to display the first N items that match the query. Therefore, for N small enough, it should not be a big issue loading the matching items from the database. Besides, caching items in main memory can make retrieval faster. I think the main problem is how to find the matching items quickly, given the pattern string. Can I rely on some DBMS facilities, or do I have to build some in-memory index myself? Any ideas? EDIT I have run a first experiment. I have split the records into different text files (at most 200 records per file) and put the files in different directories (I used the content of one data field to determine the directory tree). I end up with about 50000 files in about 40000 directories. I have then run Lucene to index the files. Searching for a string with the Lucene demo program is pretty fast. Splitting and indexing took a few minutes: this is totally acceptable for me because it is a static data set that I want to query. The next step is to integrate Lucene in the main program and use the hits returned by Lucene to load the relevant records into main memory.

• I can't delete a directory inside a junctioned directory

  - by Fredy Muñoz

  So this is the deal. A couple of days ago I moved my profile folder C:\Documents and Settings\fmunoz to a different drive D:\fmunoz. Today, I created a directory in my desktop using the point-and-click method: Right-click on an empty space in the desktop Select New Select Folder Leave the default name New Folder and press Enter I tried to delete the folder using the point-and-click method: Right-click the New Folder directory Select Delete After five seconds, I got the following message: --------------------------- Error Deleting File or Folder --------------------------- Cannot delete New Folder: Access is denied. Make sure the disk is not full or write-protected and that the file is not currently in use. --------------------------- Initially I thought that there must be some sort of indexing services locking the directory so I got a list of open files using the TuneUp Process Manager tool but the New Folder directory wasn't there. I double-clicked My Computer, navigated to the desktop directory C:\Documents and Settings\fmunoz\Destkop, tried to delete the New Folder directory using the same point-and-click method described above and got exactly the same message at the same amount of time. In the same window, I navigated to the actual location of the desktop directory D:\fmunoz\Desktop, tried to delete the New Folder directory and this time it worked. I thought that this behavior was due to some special treatment that Windows gives to the desktop or the profile directories so I tried doing the same thing with a different set of directories: Created a folder D:\dummy Created a junction C:\dummy pointing to D:\dummy Created a New Folder directory in C:\dummy Tried to delete New Folder from C:\dummy. Didn't work. Tried to delete New Folder from D:\dummy. It worked. I tried creating the folder in the actual directory rather than the junction directory: Created a New Folder directory in D:\dummy Tried to delete New Folder from C:\dummy. Didn't work. Tried to delete New Folder from D:\dummy. It worked. I also tried using the Delete button instead of using the Delete option of the context menu but it didn't work. When using the Shift+Delete sequence, it works. It also works by using the rd command in the console, but in both cases the deleted directory doesn't goes to the Recycle Bin, which is my intention when using the Delete context menu option or the Delete button.

• How can I mount an image from an external HDD to a partition within the host system?

  - by HardwareMuch

  I'm currently using Acronis True Image Home 2010 and I have created an image of my Windows 7 OS. I copied it to my external HDD and I repartitioned my other PC's HDD. The primary partition houses the Windows Xp system which also has Acronis installed. The new partition is logical. Whenever I try to go through the steps on "Clone Disk" the program would not let me select a destination drive if I choose the external HDD as the source. I also did not know that it you can only select disks instead of partitions as a source or destination. Any suggestions would be greatly appreciated. Thanks.

It's a slave name server in my nameserver "farm". Technically I have ns1 (being the master) and ns2/ns3. Currently ns1/ns2 are down for maintenance, so I left ns3 at it serving live traffic. That's the point, DNS is supposed to be resilient. Now the odd part is, "1.2.3.4" was serving requests for example.com just fine for the last 4-5 days. This morning I get a phone call that it's non-responsive. After investigation I see the message you see above, SERVFAIL. I looked into the zone file and saw the following: example.com IN SOA ns1.example.com. hostmaster.mail.example.com. ( I wondered if at this point that the nameserver thought it was not authoritative over example.com and adjusted it to the following: example.com IN SOA ns3.example.com. hostmaster.mail.example.com. ( After that, it started responding again for all authoritative queries for example.com. I have no idea why. I thought these things were supposed to be normalized upon zone transfer from ns1 - ns3? Can someone please example why this happened and how to prevent it from happening in the future? I've never had a similar problem, and because I don't understand it well, I might be missing some critical information in this question. So please let me know if I can further add any detail to make things clearer as well. One more thing to note: I have other domains that I'm authoritative for that have their SOA still saying ns1.example.com. and not ns3.example.com. Those domains are serving requests just fine! Is it a matter of time before they stop also and I have to change SOA to ns3.example.com? Is this also only required because ns1 and ns2 are currently offline?

• Test JPQL with NetBeans IDE 7.3 Tools

  - by Geertjan

  Since I pretty much messed up this part of the "Unlocking Java EE 6 Platform" demo, which I did together with PrimeFaces lead Çagatay Çivici during JavaOne 2012, I feel obliged to blog about it to clarify what should have happened! In my own defense, I only learned about this feature 15 minutes before the session started. In 7.3 Beta, it works for Java SE projects, while for Maven-based web projects, you need a post 7.3 Beta build, which is what I set up for my demo right before it started. Then I saw that the feature was there, without actually trying it out, which resulted in that part of the demo being a bit messy. And thanks to whoever it was in the audience who shouted out how to use it correctly! Screenshots below show everything related to this new feature, available from 7.3 onwards, which means you can try out your JPQL queries right within the IDE, without deploying the application (you only need to build it since the queries are run on the compiled classes): SQL view: Result view for the above: Here, you see the result of a more specific query, i.e., check that a record with a specific name value is present in the database: Also note that there is code completion within the editor part of the dialog above. I.e., as you press Ctrl-Space, you'll see context-sensitive suggestions for filling out the query. All this is pretty cool stuff! Saves time because now there's no need to deploy the app to check the database connection.

• Entity communication: Message queue vs Publish/Subscribe vs Signal/Slots

  - by deft_code

  How do game engine entities communicate? Two use cases: How would entity_A send a take-damage message to entity_B? How would entity_A query entity_B's HP? Here's what I've encountered so far: Message queue entity_A creates a take-damage message and posts it to entity_B's message queue. entity_A creates a query-hp message and posts it to entity_B. entity_B in return creates an response-hp message and posts it to entity_A. Publish/Subscribe entity_B subscribes to take-damage messages (possibly with some preemptive filtering so only relevant message are delivered). entity_A produces take-damage message that references entity_B. entity_A subscribes to update-hp messages (possibly filtered). Every frame entity_B broadcasts update-hp messages. Signal/Slots ??? entity_A connects an update-hp slot to entity_B's update-hp signal. Something better? Do I have a correct understanding of how these communication schemes would tie into a game engine's entity system? How do entities in commercial game engines communicate?

• Conventions for search result scoring

  - by DeaconDesperado

  I assume this type of question is more on-topic here than on regular SO. I have been working on a search feature for my team's web application and have had a lot of success building a multithreaded, "divide and conquer" processing system to work through a large amount of fulltext. Our problem domain is pretty specific. Users of the app generate posts, and as a general rule, posts that are more recent are considered to be of greater relevance. Some of the data we are trying to extract from search is very specific (user's feelings about specific items or things) and we are using python nltk to do named-entity extraction to find interesting likely query terms. Essentially we look for descriptive adjective-noun pairs and generate a general picture of a user's expressed sentiment as a list of tokens. This search is intended as an internal tool for our team to draw out a local picture of sentiments like "soggy pizza." There's some machine learning in there too to do entity resolution on terms like "soggy" to all manner of adjectives expressing nastiness. My problem is I am at a loss for how to go about scoring these results. The text being searched is split up into tokens in a list, so my initial approach would be to normalize a float score between 0.0-1.0 generated off of how far into the list the terms appear and how often they are repeated (a later mention of the term being worth less, earlier more, greater frequency-greater score, etc.) A certain amount of weight could be given to the timestamp as well, though I am not certain how to calculate this. I am curious if anyone has had to solve a similar problem in a search relevance grading between appreciable metrics (frequency, term location/colocation, recency) and if there are and guidelines for how to weight each. I should mention as well that the final fallback procedure in the search is to pipe the query to Sphinx, which has its own scoring practices. Sphinx operates as the last resort in case our application specific processing can't find any eligible candidates.
