Extracting ""((Adj|Noun)+|((Adj|Noun)(Noun-Prep)?)(Adj|Noun))Noun"" from Text (Justeson & Katz, 1995)

- by ssuhan

I would like to query if it is possible to extract ((Adj|Noun)+|((Adj|Noun)(Noun-Prep)?)(Adj|Noun))Noun proposed by Justeson and Katz (1995) in R package openNLP? That is, I would like to use this linguistic filtering to extract candidate noun phrases. I cannot well understand its meaning. Could you do me a favor to explain it or transform such representation into R language. Many thanks. Maybe we can start the sample code from: library("openNLP") acq <- "This paper describes a novel optical thread plug gauge (OTPG) for internal thread inspection using machine vision. The OTPG is composed of a rigid industrial endoscope, a charge-coupled device camera, and a two degree-of-freedom motion control unit. A sequence of partial wall images of an internal thread are retrieved and reconstructed into a 2D unwrapped image. Then, a digital image processing and classification procedure is used to normalize, segment, and determine the quality of the internal thread." acqTag <- tagPOS(acq) acqTagSplit = strsplit(acqTag," ")

What does it mean for the file name to be shown with red background

- by user56614

I'm trying to install Cisco VPN client on Linux Ubuntu 10.04. The installer creates the directory, places all the necessary files in it, and then fails to launch the binary. I tried to launch it myself, the system rebukes me too. Closer inspection yields the following: eugene@eugene-desktop:/opt/cisco/vpn/bin$ sudo chmod u+x vpnagentd eugene@eugene-desktop:/opt/cisco/vpn/bin$ ls -la total 5124 drwxr-xr-x 2 root root 4096 2010-10-23 11:51 . drwxr-xr-x 6 root root 4096 2010-10-23 11:51 .. -rwxr-xr-x 1 root root 1607236 2010-10-23 11:51 vpn -rwsr-xr-x 1 root root 1204692 2010-10-23 11:51 vpnagentd -r--r--r-- 1 root root 697380 2010-10-23 11:51 vpndownloader.sh -rwxr-xr-x 1 root root 1712708 2010-10-23 11:51 vpnui -rwxr-xr-x 1 root root 3654 2010-10-23 11:51 vpn_uninstall.sh eugene@eugene-desktop:/opt/cisco/vpn/bin$ ./vpnagentd bash: ./vpnagentd: No such file or directory eugene@eugene-desktop:/opt/cisco/vpn/bin$ sudo ./vpnagentd sudo: unable to execute ./vpnagentd: No such file or directory The file name "vpnagentd" is shown in white letters with red background. The other three executables are in green letters with black background, as expected. Any ideas?

Wireless Drivers for Broadcom BCM 4321 (14e4:4329) will not stay connected to a wireless network

- by Eugene

So, I'm not necessary new to Linux, I just never took the time to learn it, so please, bare with me. I just swapped out one of my wireless cards from one computer to another. This wireless card in question would be a "Broadcom BCM4321 (14e4:4329)" or actually a "Netgear WN311B Rangemax Next 270 Mbps Wireless PCI Adapter", but that's not important. I've tried (but probably screwed up in the process) installing the "wl" , "b43" and "brcmsmac" drivers, or at least I think I did. Currently I have only the following drivers loaded: eugene@EugeneS-PCu:~$ lsmod | grep "brcmsmac\|b43\|ssb\|bcma\|wl" b43 387371 0 bcma 52096 1 b43 mac80211 630653 1 b43 cfg80211 484040 2 b43,mac80211 ssb_hcd 12869 0 ssb 62379 2 b43,ssb_hcd The main issue is that with most of the drivers available that I've installed, they will find my wireless network but, they will only stay connected for about a minute with abnormally slow speed and then all of a sudden disconnect. Currently, the computer is hooked into another to share it's connect so that I can install drivers from the internet instead of loading them on to a flash drive and doing it offline. If anyone has any insight to the problem, that would be awesome. If not, I'll probably just look up how to install the Windows closed source driver. Edit 1: Even when I try the method here, as suggested when this was marked as a duplicate, I still can't stay connected to a wireless network. Edit 2: After discussing my issue with @Luis, he opened my question back up and told me to include the tests/procedures in the comments. Basically I did this: Read the first answer of the link above when this question was marked as duplicate which involved installing removing bcmwl-kernel-source and instead install firmware-b43-installer and b43-fwcutter. No change of result and contacted Luis in the comments, who then told me to try the second answer which involved removing my previous mistake and installing bcmwl-kernel-source Now the Network Manger (this has happend before, but usally I fixed it by using a different driver) even recognizes WiFi exist (both non-literal and literal). Luis who then suggested sudo rfkill unblock all rfkill unblock all didn't return anything, so I decide to try sudo rfkill list all. Returns nothing (no wonder rfkill unblock all did nothing). I enter lsmod | grep "brcmsmac\|b43\|ssb\|bcma\|wl" and that returns nothing. Try loading the driver by entering sudo modprobe b43 and try lsmod | grep "brcmsmac\|b43\|ssb\|bcma\|wl" again. Returns this: eugene@Eugenes-uPC:~$ sudo modprobe b43 eugene@Eugenes-uPC:~$ lsmod | grep "brcmsmac\|b43\|ssb\|bcma\|wl" b43 387371 0 bcma 52096 1 b43 mac80211 630653 1 b43 cfg80211 484040 2 b43,mac80211 ssb_hcd 12869 0 ssb 62379 2 b43,ssb_hcd So to recap: Currently Network Manager doesn't recognize Wireless exists, b43 drivers are loaded and I've currently hardwired a connect from my laptop to the computer that's causing this.

"Zend Optimizer not installed" after I updated to Ubuntu 10.04

- by Eugene

Hi guys, I've just updated from 9.10 to 10.04. Everything seems to run fine except for zend optimizer which is throwing "Zend Optimizer not installed" error. I went to php.ini and the following line is still there Code: zend_extension=/etc/php5/ZendOptimizer.so Also I checked that the file does exist and that the php.ini I am looking at is in fact the php.ini file that is being used by the server. Please let me know if you have any ideas about how to fix or debug this. Thanks, Eugene

How does the ? make a quantifier lazy in regex

- by Uriel Katz

I've been looking into regex lately and figured that the ? operator makes the *,+, or ? lazy. My question is how does it do that? Is it that *? for example is a special operator, or does the ? have an effect on the *? In other words, does regex recognize *? as one operator in itself, or does regex recognize *? as the two separate operators * and ?? If it is the case that *? is being recognized as two separate operators, how does the ? affect the * to make it lazy. If ? means that the * is optional, shouldn't this mean that the * doesn't have to exists at all. If so, then in a statement .*? wouldn't regex just match separate letters and the whole string instead of the shorter string? Please explain, I'm desperate to understand.

nginx+passenger +static websites= problems

- by Eugene K

I've got a Rails app that nginx serves through passenger. I'd also like to serve some static content for a different domain name. But when I add another server block to my config, both websites become unavailable returning HTTP 204. What have I done wrong? What can I do to fix it? Here's the http block of my nginx.conf: https://gist.github.com/4243256 Here's what I added : server { listen 80; server_name website2; root /var/www/website2; location / { index index.html; } } It's going to be a Rails app as well at some point in the future (though I'm not really sure about that, maybe I'm going to use a different back-end solution.) Either way, I don't want anything dynamic to eat away the resources just yet. As of now, this website consists of nothing but index.html and stylesheet.css files in the root directory. What should I do? Thank you in advance. Sincerely yours, Eugene.

Interesting things – Twitter annotations and your phone as a web server

- by jamiet

I overheard/read a couple of things today that really made me, data junkie that I am, take a step back and think, “Hmmm, yeah, that could be really interesting” and I wanted to make a note of them here so that (a) I could bring them to the attention of anyone that happens to read this and (b) I can maybe come back here in a few years and see if either of these have come to fruition. Your phone as a web server While listening to Jon Udell’s (twitter) “Interviews with Innovators Podcast” today in which he interviewed Herbert Van de Sompel (twitter) about his Momento project. During the interview Jon and Herbert made the following remarks: Jon: [some people] really had this vision of a web of servers, the notion that every node on the internet, every connected entity, is potentially a server and a client…we can see where we’re getting to a point where these endpoint devices we have in our pockets are going to be massively capable and it may be in the not too distant future that significant chunks of the web archive will be cached all over the place including on your own machine… Herbert: wasn’t it Opera who at one point turned your browser into a server? That really got my brain ticking. We all carry a mobile phone with us and therefore we all potentially carry a mobile web server with us as well and to my mind the only thing really stopping that from happening is the capabilities of the phone hardware, the capabilities of the network infrastructure and the will to just bloody do it. Certainly all the standards required for addressing a web server on a phone already exist (to this uninitiated observer DNS and IPv6 seem to solve that problem) so why not? I tweeted about the idea and Rory Street answered back with “why would you want a phone to be a web server?”: Its a fair question and one that I would like to try and answer. Mobile phones are increasingly becoming our window onto the world as we use them to upload messages to Twitter, record our location on FourSquare or interact with our friends on Facebook but in each of these cases some other service is acting as our intermediary; to see what I’m thinking you have to go via Twitter, to see where I am you have to go to FourSquare (I’m using ‘I’ liberally, I don’t actually use FourSquare before you ask). Why should this have to be the case? Why can’t that data be decentralised? Why can’t we be masters of our own data universe? If my phone acted as a web server then I could expose all of that information without needing those intermediary services. I see a time when we can pass around URLs such as the following: http://jamiesphone.net/location/current - Where is Jamie right now? http://jamiesphone.net/location/2010-04-21 – Where was Jamie on 21st April 2010? http://jamiesphone.net/thoughts/current – What’s on Jamie’s mind right now? http://jamiesphone.net/blog – What documents is Jamie sharing with me? http://jamiesphone.net/calendar/next7days – Where is Jamie planning to be over the next 7 days? and those URLs get served off of the phone in our pockets. If we govern that data then we can control who has access to it and (crucially) how long its available for. Want to wipe yourself off the face of the web? its pretty easy if you’re in control of all the data – just turn your phone off. None of this exists today but I look forward to a time when it does. Opera really were onto something last June when they announced Opera Unite (admittedly Unite only works because Opera provide an intermediary DNS-alike system – it isn’t totally decentralised). Opening up Twitter annotations Last week Twitter held their first developer conference called Chirp where they announced an upcoming new feature called ‘Twitter Annotations’; in short this will allow us to attach metadata to a Tweet thus enhancing the tweet itself. Think of it as a richer version of hashtags. To think of it another way Twitter are turning their data into a humongous Entity-Attribute-Value or triple-tuple store. That alone has huge implications both for the web and Twitter as a whole – the ability to enrich that 140 characters data and thus make it more useful is indeed compelling however today I stumbled upon a blog post from Eugene Mandel entitled Tweet Annotations – a Way to a Metadata Marketplace? where he proposed the idea of allowing tweets to have metadata added by people other than the person who tweeted the original tweet. This idea really fascinated me especially when I read some of the potential uses that Eugene and his commenters suggested. They included: Amazon could attach an ISBN to a tweet that mentions a book. Specialist clients apps for book lovers could be built up around this metadata. Advertisers could pay to place adverts in metadata. The revenue generated from those adverts could be shared with the tweeter or people who add the metadata. Granted, allowing anyone to add metadata to a tweet has the potential to create a spam problem the like of which we haven’t even envisaged but spam hasn’t halted the growth of the web and neither should it halt the growth of data annotations either. The original tweeter should of course be able to determine who can add metadata and whether it should be moderated. As Eugene says himself: Opening publishing tweet annotations to anyone will open the way to a marketplace of metadata where client developers, data mining companies and advertisers can add new meaning to Twitter and build innovative businesses. What Eugene and his followers did not mention is what I think is potentially the most fascinating use of opening up annotations. Google’s success today is built on their page rank algorithm that measures the validity of a web page by the number of incoming links to it and the page rank of the sites containing those links – its a system built on reputation. Twitter annotations could open up a new paradigm however – let’s call it People rank- where reputation can be measured by the metadata that people choose to apply to links and the websites containing those links. Its not hard to see why Google and Microsoft have paid big bucks to get access to the Twitter firehose! Neither of these features, phones as a web server or the ability to add annotations to other people’s tweets, exist today but I strongly believe that they could dramatically enhance the web as we know it today. I hope to look back on this blog post in a few years in the knowledge that these ideas have been put into place. @Jamiet Share this post: email it! | bookmark it! | digg it! | reddit! | kick it! | live it!

Force Capistrano to ask for password

- by Moshe Katz

I am deploying using Capistrano to a new server and having the following issue. Currently, I cannot add an SSH key to the server to log in with so I must use password authentication. However, I do have a key for another server saved in my local user account's .ssh directory. Here is the error I get when I try to log in: C:\Web\CampMaRabu>cap deploy:setup * executing `deploy:setup' * executing "mkdir -p /home2/webapp1 /home2/webapp1/releases /home2/webapp1/shared /home2/webapp1/shared/system /home2/webapp1/shared/log /home2/webapp1/shared/pids" servers: ["myserver.example.com"] connection failed for: myserver.example.com (OpenSSL::PKey::PKeyError: not a public key "C:/Users/MyAccount/.ssh/id_rsa.pub") How can I get Capistrano to ignore the existence of the key I have and let me log in with a password instead? I tried adding set :password, "myp@ssw0rd" to deploy.rb and it didn't help.

What's the best method to save the player's data to the server? Method to store the game saves Which one of the following method should I use ? Using a database structure(e.g.. mySQL) to store the game data as blobs? Using the server hard disk to store the saved game data as binary data files? Method to send saved game data to server What method should I use ? socketIO web socket a web-based scripting language to receive the game data as binary? for example, a php script to handle binary data and save it to file Meta-data I read that some games store saved game meta-data in database structures. What kind of meta data is useful to store?

DNS server failure when forwarding

- by Abraham Katz

I run Bind 9 on a Ubuntu 12.04 server. I want this server to be a sort of a "wrapper" over my default server, so that it will respond to "domain_name.My_TLD" itself and forward requests to any other request. The server resides in a domain (Disconnected from the internet), so I configured it to zone "company_domain."{ type forward; forwarders { 1.2.3.4 }; #the DC's ip }; When i query it about sommething.company_domain. it sends a query to the DC and gets a response, but it returns "server failure". What can cause that? Cheers, Abraham

Dapper and object validation/business rules enforcement

- by Eugene

This isn't really Dapper-specific, actually, as it relates to any XML-serializeable object.. but it came up when I was storing an object using Dapper. Anyways, say I have a user class. Normally, I'd do something like this: class User { public string SIN {get; private set;} public string DisplayName {get;set;} public User(string sin) { if (string.IsNullOrWhiteSpace(sin)) throw new ArgumentException("SIN must be specified"); this.SIN = sin; } } Since a SIN is required, I'd just create a constructor with a sin parameter, and make it read-only. However, with a Dapper (and probably any other ORM), I need to provide a parameterless constructor, and make all properties writeable. So now I have this: class User: IValidatableObject { public int Id { get; set; } public string SIN { get; set; } public string DisplayName { get; set; } public IEnumerable<ValidationResult> Validate(ValidationContext validationContext) { // implementation } } This seems.. can't really pick the word, a bad smell? A) I'm allowing to change properties that should not be changed ever after an object has been created (SIN, userid) B) Now I have to implement IValidatableObject or something like that to test those properties before updating them to db. So how do you go about it ?

Calculating adjacent quads on a quad sphere

- by Caius Eugene

I've been experimenting with generating a quad sphere. This sphere subdivides into a quadtree structure. Eventually I'm going to be applying some simplex noise to the vertices of each face to create a terrain like surface. To solve the issue of cracks I want to be able to apply a geomitmap technique of triangle fanning on the edges of each quad, but in order to know the subdivision level of the adjacent quads I need to identify which quads are adjacent to each other. Does anyone know any approaches to computing and storing these adjacent quads for quick lookup? Also It's important that I know which direction they are in so I can easily adjust the correct edge.

To have multiple sites with similar content on the same server but different IPs?

- by Eugene

I have 7 different sites on the same dedicated server. Two major sites have different IPs, and 5 small share the same IP. About first 2 they have similar content, but not the same. Basically they have different: URLs Titles Meta Data But they both have the same niche. I was thinking about two strategies. One is to move one of the sites (from 2 first one) on different server or move 5 other sites on different server. But I'm not sure which way is better. My questions are: Wouldn't be better from SEO stand point, to move those 2 sites on different servers? Does it worth it to spend for additional server? Do you know if Google penalize sites for similar content on the same server with different IPs?

Word 2013 can't compare readonly files

- by Moshe Katz

I am using Tortoise SVN to work with a repository that contains some documentation saved as Word documents. On my old computer, with Office 2010, I was able to compare with previous revisions. Tortoise would open Word in compare view so I could see the differences between the files. I have installed Office 2013 (final version from Technet, not the preview version) on my new laptop for testing and now I can no longer compare Word Documents. Tortoise pops up a generic error that it was unable to compare the two files. Tortoise uses a JScript file to interface with Word, so I ran that file through a debugger and found that the actual error is: The Compare method or property is not available because this command is not available for reading. Some Googling followed by some testing revealed that the error is caused by the first file opened (in this case, the previous version) being opened as Read-Only. If I change the JScript code to open in normal mode, and I find the file on the system and un-check the "Read Only" property (if necessary), then the comparison opens as expected. I was unable to find any documentation about this change to Word on any Microsoft site. Does anyone know why this has been changed, and if it is intentional and not a bug, what the benefit is of requiring the file to be writable in order to compare it with another? Note: This is tagged word-2013-preview but it is actually for the release version of Word that is available on MSDN and Technet. I do not have enough rep. on this site to create new tags (yet).

Why Beta versions have so many bugs?

- by Eugene

When I worked in Microsoft on MSE antivirus, we had several stages of pre-release: Alpha, Beta, RC. The biggest difference between these stages were bug fixes. Each time we fixed more bugs, and usually updated some minor features. Apple works in the same way. Look here: http://www.techrepublic.com/article/pro-tip-how-to-create-a-bootable-usb-installer-for-os-x-yosemite/ They released a beta of Yosemite OS, but the beta is full of bugs. Why do these big companies work like this? Isn't it better to release a beta version that was tested very thoroughly but one that just doesn't provide all the features that the final version will provide?

Quadtree collapsing

- by Caius Eugene

Okay so i've spent a few days learning what a quadtree is and how to implement one. So far I have a quadtree that when I click inside a leaf it subdivides, I wondering how do I get the previous subdivisions to collapse back up, so that only one area is subdivided at a time? This is what mine looks like: (1. initial mouse click) (2. another mouse click) The aim to to eventually track the position of my mouse and subdivide the area it is in dynamically. THE OVERALL aim it to use this to create a terrain mesh and subdivide based on the camera. But I've gone right back to basics to get an understanding of how this will work. Any advice would be grand! - Caius

Demystifying "chunked level of detail"

- by Caius Eugene

Just recently trying to make sense of implementing a chunked level of detail system in Unity. I'm going to be generating four mesh planes, each with a height map but I guess that isn't too important at the moment. I have a lot of questions after reading up about this technique, I hope this isn't too much to ask all in one go, but I would be extremely grateful for someone to help me make sense of this technique. 1 : I can't understand at which point down the Chunked LOD pipeline that the mesh gets split into chunks. Is this during the initial mesh generation, or is there a separate algorithm which does this. 2 : I understand that a Quadtree data structure is used to store the Chunked LOD data, I think i'm missing the point a bit, but Is the quadtree storing vertex and triangles data for each subdivision level? 3a : How is the camera distance usually calculated. When reading up about quadtree's, Axis-aligned bounding box's are mentioned a lot. In this case would each chunk have a collision bounding box to detect the camera or player is nearby? or is there a better way of doing this? (raycast maybe?) 3b : Do the chunks calculate the camera distance themselves? 4 : Does each chunk have the same "resolution". for example at top level the mesh will be 32x32, will each subdivided node also be 32x32. Example below:

Purple screen on boot, iMac

- by Eugene B

I have just installed Ubuntu 13.10 (special iMac iso found here) on the new iMac (dual boot). Installation of rEFIt was completed successfully, as well as the installation of Ubuntu itself. After the final reboot, rEFIt sees this distributive and allows the choice. When I select "Boot linux from HD", it sends me to grub screen, where I can select Ubuntu. And then it gets stuck on the purple screen (smpboot: Booting Node 0, Processors #1 -- for the recovery mode) with no further action. Does anybody know a solution to this problem? P.S.: I have also tried both 32 and 64-bit pc distributives (occasionally) with the same result.

I am trying to a make checkers in visual basic with ai.

I am pissed of and have been trying to fix it for over a week now, I would really appreciate it if someone could help me out here. I have 3 years experience of programming (in Java, only about of month of VB experience) and I always am able to solve all my errors on my own so I don't know why I can't get this to work.

Unable to wake display with remote

- by Eugene

I'm running an HTPC (xbmc) without a keyboard/mouse attached, running oneiric. After some indeterminate amount of time, sometime between 1 and 12 hours, the display goes to sleep. The computer itself is not sleeping, I can still SSH to it from another computer. The remote will not wake the display. The IR receiver is working, as irw will show me the remote key presses. The only way to get my display back is to restart the display manager, lightdm in this case. Does anybody know a way to keep the display from going to sleep? I don't really need any power management at all considering that it connects to my TV and when I want my display to go to sleep, I turn off my TV.
