• Can not connect remotely to MySQL Server on Ubuntu 10.10

  - by BobFranz

  Ok I have searched google for two days trying to get this to work. Here are the steps I have taken so far: Clean install of Ubuntu 10.10 Install mysql 5.1 as well as admin Comment out the bind address in the config file Create a new database Create a new user that is username@% to allow remote connections Grant all access to this user to the new database EXCEPT the grant option Login on the server is ok using this new user and database on the localhost Login on the server is ok using this new user and database on the server internal network ip Login from a remote computer is ok using this new user and database using the internal network ip Login is not working when logging in with this username and database using the external ip address from the server or the remote computer. I have port forwarding enabled for this port and it is viewable from outside as confirmed by canyouseeme.org I have nmap'd using the following command on the internal ip and get the below result: nmap -PN -p 3306 192.168.1.73 Starting Nmap 5.21 ( http://nmap.org ) at 2011-02-19 13:41 PST Nmap scan report for computername-System-Name (192.168.1.73) Host is up (0.00064s latency). PORT STATE SERVICE 3306/tcp open mysql Nmap done: 1 IP address (1 host up) scanned in 0.23 seconds I have nmap'd using the following command on the internal ip and get the below result(I have hidden ip for obvious reasons): nmap -PN -p 3306 xxx.xxx.xx.xxx Starting Nmap 5.21 ( http://nmap.org ) at 2011-02-19 13:42 PST Nmap scan report for HOSTNAME (xxx.xxx.xx.xxx) Host is up (0.00056s latency). PORT STATE SERVICE 3306/tcp closed mysql Nmap done: 1 IP address (1 host up) scanned in 0.21 seconds I am completely stuck here and need some help. I have tried everything under the moon and still can not connect from a remote external ip address. Any help is greatly appreciated and I need to do anything to help find the problem let me know and I will post the results here.

• apache/httpd responds slower under EL6.1 than EL5.6 (centos)

  - by daniel

  I've read through other threads on performance differences between RHEL6 and RHEL5, but none seem a tight match to mine. My issue manifests itself in slightly slower average response time (20ms) per request. I have about 10/10 servers of the same hardware spec with Cent6.1 and Cent5.6. The issue is consistent across the group. I am running Ruby on Rails with Passenger. Apache config is identical (checked out from the same SVN repo) Ruby and Passenger are identical builds. Application is identical and being served traffic round robin. mod_worker An interesting clue from server-status: The Cent6.1 servers have a steady 20-40 threads in the "Reading Request" state while the Cent5.6 servers have around 1. I'm graphing this so I can see it trend over time. I also have a bunch of much newer machines that are significantly faster and are running Cent6.1. They dust all the older machines in response time, but I can see they also have a steady 20-40 threads in the "Reading Request" state. This makes me believe I can get their response time down, if I can figure out what is holding up these requests. My gut is telling me that I need to tune some network setting in sysctl, but I haven't figured it out yet. Help is appreciated.

• Windows 7 misses keystrokes from internal keyboard after hibernation (on Acer Aspire 5820)

  - by ron

  I face a very strange symptom on my Acer Aspire laptop (with the factory default Win7 install and divers. Windows update running). After waking the computer from hibernation, it is a pain to type, since on average 5-10 keypresses are missing per 100 presses, using the laptop's keyboard. Steps to reproduce: 1) Power off 2) Power on, wait for system to become usable 3) Open notepad, for 5 times do hit 10x the same character. This gives a similar pattern of 50 chars total: xxxxxxxxxxyyyyyyyyyyaaaaaaaaaassssssssssdddddddddd 4) Optionally repeat. Everything is fine this far. 5) Hibernate. 6) Power on and resume. 7) Repeat steps 3)-4). This time approximately 3-5 character will be missing from each 50 characters. What I ruled out: putting to Sleep or just Locking and resuming from there does not cause problem battery / AC usage does not matter net connection does not matter running processes seem to be the same before and after hibernation key press speed doesn't really matter. For the test I use a nominal 3-5 strokes/second beat. plugging in an external USB keyboard works fine, but the built-in one still misbehaves What could be the problem? How could I diagnose if the keypresses arrive in, but get swallowed at some point? (maybe some nasty keyboard handler hook misbehaves?). Update: It seems that pushing the PowerSmart button and toggling to power saving state fixes the problem. Also, toggling it again back to the original state keeps it fixed. So this may be a fine workaround, but is not a conforming solution.

• zfs pool error, how to determine which drive failed in the past

  - by Kendrick

  I had been copying data from my pool so that I could rebuild it with a different version so that I could go away from solaris 11 and to one that is portable between freebsd/openindia etc. it was copying at 20mb a sec the other day which is about all my desktop drive can handle writing from the network. suddently lastnight it went down to 1.4mb i ran zpool status today and got this. pool: store state: ONLINE status: One or more devices has experienced an unrecoverable error. An attempt was made to correct the error. Applications are unaffected. action: Determine if the device needs to be replaced, and clear the errors using 'zpool clear' or replace the device with 'zpool replace'. see: http://www.sun.com/msg/ZFS-8000-9P scan: none requested config: NAME STATE READ WRITE CKSUM store ONLINE 0 0 0 raidz1-0 ONLINE 0 0 0 c8t3d0p0 ONLINE 0 0 2 c8t4d0p0 ONLINE 0 0 10 c8t2d0p0 ONLINE 0 0 0 it is currently a 3 x1tb drive array. what tools would best be used to determine what the error was and which drive is failing. per the admin doc The second section of the configuration output displays error statistics. These errors are divided into three categories: READ – I/O errors occurred while issuing a read request. WRITE – I/O errors occurred while issuing a write request. CKSUM – Checksum errors. The device returned corrupted data as the result of a read request. it was saying low counts could be any thing from a power flux to a disk event but gave no suggestions as to what tools to check and determine with.

• Why does pulling the power cord then pressing the power button fix a non-booting PC?

  - by sidewaysmilk

  I've been working at this institution for about 6 years. One thing thing that I've always found curious is that sometimes—especially after a power outage—we find a PC that won't boot when the power button is pressed. Usually, the fans will spin up, but it won't POST. Our solution is to pull the power cord, press the power button with the computer unplugged, then plug it in and turn it on. It seems more common with Gateway brand PCs than the Dells or HPs that we have around. Does anybody know what pressing the power button does when the computer is unplugged? I have some vague notion that closing the power button circuit allows some capacitors to discharge or something, but I'd like a firmer answer to offer my users when they ask me what I'm doing. My best guess as to why fans can spin but it can't POST is that the BIOS is in some non-functional state. I don't know how BIOS stores state, but my best guess is that there is some residual garbage in its registers or something, like the stack pointer isn't starting at 0 maybe?

• Grub Installation Failed: Fatal Error ... now what I do?

  - by eklavya

  I know there are some threads that touch this but I feel I have done something uniquely stupid. hence the post and plea for help. I am a beginner @ Linux. So I have a PC with a HDD (hard disk drive) and SSD (solid state drive) It was running Linux Mint /dev/sda1 - HDD Partition 1 - 2 TB (mounted this is /home /dev/sda2 - HDD Partition 2 - 1 TB (separate back up drive, i was backing up files to this) /dev/sdb1 - SSD Partition 1 - 100 GB (OS) /dev/sdb2 - SSD Partition 2 - 20 GB (Swap) The operating system was Linux Mint and was installed on the /dev/sdb1 i.e the solid state drive. I had partitioned off the sda into 2 TB and 1TB and presented the 2 TB as the /home to the OS. Anyway last night I decided to make a return to Ubuntu via the path of Elementary OS. Everything went fine with the install until it stated that GRUB installed failed and this was a Fatal error (no kidding I said). No I am stuck. I have definitely done something wrong and don't know what it is... My biggest pain is the files on the /dev/sda2. I want to save these before I try something drastic like wiping off the /dev/sda completely. So I have the following questions... Can I use a liveCD USB to save these files ? I can see the /dev/sda2 but was unable to access the files in the liveCD last not least ... how do I fix the main issue here. Why could the OS not install GRUB 2b... why is my SSD the /dev/sdb ... and not /dev/sda. Does that have something to do with it that my master boot record sits on the HDD /dev/sda and not /dev/sdb

• Always maximize almost maximized window utility

  - by AbstractDissonance

  It drives me nuts when a window is nearly maximized but not quite and when I go to close/move/scroll it I end up bringing up the window behind it. This happens all the time with acrobat. It seems that it's default non-minimized state is usually an "almost" maximized windowed. Is there any utility that will maximize a window when it is open or size changed when it is near the size of the monitor. I'll never have any need to have a window 99% the size of the window with it centered. Why? Because it behaves just as a maximized window by obscuring all(well, almost all) the windows behind it. (It should be only the main window of an application that is affected) The issue seems to be a few programs like acrobat that, I guess, try to fit it's contents which, sometimes, happens to be almost the full screen but not quite making it look maximized when it is not. I do not want all windows to open maximized but have no need for the window state almost centered and almost the same size as the desktop. (I imagine most people don't)

• C# lost local variable window from debug (f11 step by step)

  - by Jane

  I was running my code (visual studio 2010) and I accidentally closed the window that shows the state of variables step by step. I think it was called locals but I can't find it on any of the menu option. Would appreciate any help on this, I didn't realize how handy it was until now - The following link is what my local window looks like when selecting debug/start debugging/selecting breakpoints, which I'm don't find helpful. This is what my window used to look like: http://www.google.co.nz/imgresum=1&hl=en&sa=N&biw=1600&bih=761&tbm=isch&tbnid=Sa5AmVW5BxxakM:&imgrefurl=http://www.codeproject.com/Articles/79508/Mastering-Debugging-in-Visual-Studio-2010-A-Beginn&docid=4Iskh8P-E7oVSM&imgurl=http://www.codeproject.com/KB/cs/MasteringInDebugging/debug30_small.png&w=640&h=228&ei=TjKBUKGwKcXVsgauvIGYDQ&zoom=1&iact=hc&vpx=1119&vpy=441&dur=1559&hovh=134&hovw=376&tx=219&ty=79&sig=104270260849502265426&page=1&tbnh=91&tbnw=256&start=0&ndsp=22&ved=1t:429,r:0,s:20,i:134 It's probably a mode/option within debugging I need to select but I can't figure out how to get it back to the nice and simple variable state display..

• Load Balancing is unusual in Apache in round-robin mode when one of the tomcat is brought down

  - by srayker

  We are facing a unusual behavior with round-robin load balancing on apache when one of the tomcat server is brought down. Our Setup: we have 2 apache web servers on the front end using mod_jk module for load balancing using round robin for load distribution. We also have enabled session stickyness. This is followed by 4 tomcat servers on which the applications are running. Sometimes under heavy load, if there is a slowness in our DB tier we find that eventually one of the tomcat goes into a hung state and would need a restart. The moment we bounce the tomcat we see a spike in requests in one of the server and this would also go into hung state and need a restart. Eventually all the server will face similar condition. What beats me is why does the Apache transfer the whole load to one server instead of distributing the load. We are now trying the worker.balancer.method=B to see if this helps to resolve our issue. Any thoughts on resolving the issue is greatly appreciated. regards, srayker

• IPtables and Remote Desktop with Proxy

  - by Sebastian

  So I setup a windows 2008 web server R2 on VirtualBox. Currently using Bridged Network. I can remote desktop to the machine hosting the VM (10.0.0.183) but cannot remote desktop to the VM itself (10.0.0.195). The remote port on the VM set to 5003. VM setup to accept remote connections (windows side). We also use a proxy for our internet, and I added these rules under NAT. (centOS 5) on our proxy box. -A INPUT -p tcp --dport 3389 -j ACCEPT -A REROUTING -i ppp0 -p tcp --dport 3389 -j REDIRECT --to-port 5003 -A FORWARD -d 10.0.0.195 --dport 5003 -m state --state NEW,ESTABLISHED,RELATED -j ACCEPT I've been trying for hours and hours and just cannot get it to work. I also used freedns so that we can use a domain name to connect too this VM over the internet. (the DNS points to our external IP address). If we don't get this right we will have to purchase a PPoE from an ISP to connect to this VM remotely, but I know that there is an alternative route if I can just get this port forwarding right!

• How to block access to addresses outside network (internet)

  - by devnull

  I have a homeserver, that is now connected to the internet with an own network device (ath0 - 192.168.1.x). It also has one more network interface (eth0 - 192.168.0.x). Soon I will get a second internet line that will be connected the second network. The server then has both networks with different internet lines available, but i only want it to connect to the internet on the old ath0 interface - not the new eth0 (192.168.0.x). Background of that constellation is that the new line has a volume-limit in traffic - the old hasn't and i need the new line for all mobile devices and laptops. The devices should be able to use the new network to connect to the internet and the server. The homeserver is a debian 6 with iptables and some already written rules for it. I need now a rule to block all outgoing internet access on the eth0 interface - i guess it could be something with --target != 192.168.0.0 but i did not succeed in finding the proper solution. Edit: found the solution: iptables -A OUTPUT -o eth0 -d 192.168.0.0/24 -m state --state NEW,ESTABLISHED -j ACCEPT With that setting, all traffic that uses the eth0 interface is only allowed if the destination is inside the network 192.168.0.x - all other traffic is denied .

• How can I document and automate a system's configuration?

  - by Diomidis Spinellis

  Having a system's configuration represented by its current state is risky, inefficient, and opaque. At some point you may be left with an unsupported system and no upgrade path. Then configuring a new system compatible with the old is a process or trial and error. Furthermore, if at some point the system is damaged the only option is to go back to the most recent full backup, and try to remember what changes followed from that point. Also, the only way to create a system compatible with the original is through a complete dump/restore. Finally, in such a setup there's no way to know how you solved a particular problem; the only thing you can do is to look at the corresponding configuration files and try to guess what you changed to achieve the desired effect. Currently for each system I maintain, I keep a log file where I record all system administration activity, starting from the installation: installation options, added packages, changes in configuration files, updates, problem fixes etc. In theory this allows me to (manually) replay all changes to arrive at the current state, or to unroll an erroneous change by executing the reverse commands. However, this process is also inefficient, error-prone, and relies on human judgment. Another thing I've tried is to put /etc configuration files under version control with git. This helps me document the changes automatically and also apply them on a clean setup. But it's not without problems: git has to run under sudo, passwords and private keys may be stored in the repository, installed packages can't be meaningfully tracked, and git will have a fit if I try to extend this approach to all the system's directories. I've also thought about performing all changes through shell scripts or makefiles, but I think this process will require a lot of effort and will be fragile. Are there some better methods or tools that I'm missing?

• cannot connect to my nginx server from remote machine

  - by margincall

  I thought that it's iptables problem.. but it seems not. I really have no idea about this situation. I'm getting a server hosting(CentOS). I installed Nginx + Django and nginx uses 8080 port. A domain is connected to the server. When I executed "wget [domain]:8080/[app name]/" in the server, it worked. Of course, "wget 127.0.0.1:8080/[app name]/" has no problem. (wget [server ip]:8080/[app name]/, either) However, from other computers, connecting was failed. (message says, no route) I checked my firewall setting. I excuted these commands. iptables -I INPUT -p tcp --dport 8080 -j ACCEPT iptables -I OUTPUT -p tcp --sport 8080 -j ACCEPT iptables -A RH-Firewall-1-INPUT -m state --state NEW -m tcp -p tcp --dport 8080 -j ACCEPT /etc/init.d/iptables restart I don't really understand all options of commands and I think there were useless commands, but I just tried all googled iptables settings. But still I cannot connect to my server. What should I check, first? I don't know this is important, but add to this post. On 80 port, an apache server is running. It works fine, I can connect to apache from other computers. There is DB connecting issue, (PHP to MySQL) but I think that it is just PHP coding bug. please excuse my low-level English. I'm not native English speaker.. but I tried to explane well as far as possible. Thank you for reading this question.

• ip6tables blocking output traffic

  - by jmccrohan

  My OpenVZ VPS is blocking outbound IPv6 traffic, but correctly filtering inbound IPv6 traffic. Below is my ip6tables-restore script. *filter :INPUT ACCEPT [0:0] :FORWARD ACCEPT [0:0] :OUTPUT ACCEPT [0:0] -A INPUT -i lo -j ACCEPT -A INPUT -m state --state RELATED,ESTABLISHED -j ACCEPT -A INPUT -p ipv6-icmp -j ACCEPT -A INPUT -p tcp -m tcp --dport 22 -j ACCEPT -A INPUT -p tcp -m tcp --dport 80 -j ACCEPT -A INPUT -p udp -m udp --dport 1194 -j ACCEPT -A INPUT -p tcp -m tcp --dport 51413 -j ACCEPT -A INPUT -p udp -m udp --dport 51413 -j ACCEPT -A INPUT -m limit --limit 5/min -A INPUT -j REJECT --reject-with icmp6-adm-prohibited -A FORWARD -j ACCEPT -A OUTPUT -j ACCEPT COMMIT ICMPv6 traffic is still able to pass both inbound and outbound. When I flush these rules using -F, outbound traffic flows fine. What am I missing here? EDIT: It appears that ip6tables is marking ESTABLISHED packets as INVALID. Consequently, the outbound traffic is NOT actually being blocked. The reply packets are not allowed inbound again, hence appearing like blocked outbound traffic. Allowing INVALID packets inbound solves the outbound issue, but also renders the inbound filter useless.

• Example: Communication between Activity and Service using Messaging

  - by Lance Lefebure

  I couldn't find any examples of how to send messages between an activity and a service, and spent far too many hours figuring this out. Here is an example project for others to reference. This example allows you to start or stop a service directly, and separately bind/unbind from the service. When the service is running, it increments a number at 10Hz. If the activity is bound to the service, it will display the current value. Data is transferred as an Integer and as a String so you can see how to do that two different ways. There are also buttons in the activity to send messages to the service (changes the increment-by value).

• Example: Communication between Activity and Service using Messaging

  - by Lance Lefebure

  I couldn't find any examples of how to send messages between an activity and a service, and spent far too many hours figuring this out. Here is an example project for others to reference. This example allows you to start or stop a service directly, and separately bind/unbind from the service. When the service is running, it increments a number at 10Hz. If the activity is bound to the service, it will display the current value. Data is transferred as an Integer and as a String so you can see how to do that two different ways. There are also buttons in the activity to send messages to the service (changes the increment-by value).

• Sinatra and XML POST request

  - by user292815

  I don't know is it my mistake or no. So i have that code: <code> post '/singin/get_token' do content_type :xml puts request.body.read puts xmlRequest xmlRequest = REXML::Document.new(request.body.read) ... </code> And when i post something like that: <code> <?xml version="1.0" encoding="utf-16"?><request xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema"><username>adsfasdf</username></request> </code> I receive that in my console: <code> 127.0.0.1 - - [12/Mar/2010 21:18:20] "POST /singin/get_token HTTP/1.1"

This is what I did from what ever I learnt.. In my view <% @hello.each do |key, value| %> <li><%=h "#{key.to_s} : #{value.to_s}" %></li> <% end %> This will get the entire thing converted to a list... It works awesome if its just one key.. but how to work with multiple keys and show only the information... something like when it outputs hometown : City, State rather than something like hometown : {"id"=>"115200305133358163", "name"=>"City, State"} Also for education if I just say education[school][name] to display list of schools attended? The error i get is can't convert String into Integer I also tried to do this in my controller, but I get the same error.. @fav_teams = @hello["favorite_teams"]["name"] Also, how can I save all these to the database.. something like just the list of all schools.. not their id no's? Update: The way I plan to save to my database is.. lets say for a user model, i want to save to database as :facebook_id, :facebook_name, :facebook_firstname, ...., :facebook_hometown .. here I only want to save name... when it comes to education.. I want to save.. school, concentration and type.. I have no idea on how to achieve this.. Looking forward for help! thanks!

• Android strange behavior with listview and custom cursor adapter

  - by Michael Little

  I have a problem with a list view and a custom cursor adapter and I just can't seem to figure out what is wrong with my code. Basically, in my activity I call initalize() that does a bunch of stuff to handle getting the proper data and initializing the listview. On first run of the activity you can see from the images that one of the items is missing from the list. If I go to another activity and go back to this activity the item that was missing shows up. I believe it has something to do with setContentView(R.layout.parent). If I move that to my initialize() then the item never shows up even when returning from another activity. So, for some reason, returning from another activity bypasses setContentView(R.layout.parent) and everything works fine. I know it's impossible for me to bypass setContentView(R.layout.parent) so I need to figure out what the problem is. Also, I did not include the layout because it is nothing more then two textviews. Also, the images I have attached do not show that the missing item is the last one on the list. Custom Cursor Adapter: public class CustomCursorAdapter extends SimpleCursorAdapter { private Context context; private int layout; public CustomCursorAdapter (Context context, int layout, Cursor c, String[] from, int[] to) { super(context, layout, c, from, to); this.context = context; this.layout = layout; } public View newView(Context context, Cursor cursor, ViewGroup parent) { LayoutInflater inflater = LayoutInflater.from(context); final View view = inflater.inflate(layout, parent, false); return view; } @Override public void bindView(View v, Context context, Cursor c) { if (c.getColumnName(0).matches("section")){ int nameCol = c.getColumnIndex("section"); String section = c.getString(nameCol); TextView section_text = (TextView) v.findViewById(R.id.text1); if ((section.length() > 0)) { section_text.setText(section); } else { //so we don't have an empty spot section_text.setText(""); section_text.setVisibility(2); section_text.setHeight(1); } } else if (c.getColumnName(0).matches("code")) { int nameCol = c.getColumnIndex("code"); String mCode = c.getString(nameCol); TextView code_text = (TextView) v.findViewById(R.id.text1); if (code_text != null) { int i = 167; byte[] data = {(byte) i}; String strSymbol = EncodingUtils.getString(data, "windows-1252"); mCode = strSymbol + " " + mCode; code_text.setText(mCode); code_text.setSingleLine(); } } if (c.getColumnName(1).matches("title")){ int nameCol = c.getColumnIndex("title"); String mTitle = c.getString(nameCol); TextView title_text = (TextView) v.findViewById(R.id.text2); if (title_text != null) { title_text.setText(mTitle);

• Linq-to-XML query to select specific sub-element based on additional criteria

  - by BrianLy

  My current LINQ query and example XML are below. What I'd like to do is select the primary email address from the email-addresses element into the User.Email property. The type element under the email-address element is set to primary when this is true. There may be more than one element under the email-addresses but only one will be marked primary. What is the simplest approach to take here? Current Linq Query (User.Email is currently empty): var users = from response in xdoc.Descendants("response") where response.Element("id") != null select new User { Id = (string)response.Element("id"), Name = (string)response.Element("full-name"), Email = (string)response.Element("email-addresses"), JobTitle = (string)response.Element("job-title"), NetworkId = (string)response.Element("network-id"), Type = (string)response.Element("type") }; Example XML: <?xml version="1.0" encoding="UTF-8"?> <response> <response> <contact> <phone-numbers/> <im> <provider></provider> <username></username> </im> <email-addresses> <email-address> <type>primary</type> <address>[email protected]</address> </email-address> </email-addresses> </contact> <job-title>Account Manager</job-title> <type>user</type> <expertise nil="true"></expertise> <summary nil="true"></summary> <kids-names nil="true"></kids-names> <location nil="true"></location> <guid nil="true"></guid> <timezone>Eastern Time (US &amp; Canada)</timezone> <network-name>Domain</network-name> <full-name>Alice</full-name> <network-id>79629</network-id> <stats> <followers>2</followers> <updates>4</updates> <following>3</following> </stats> <mugshot-url> https://assets3.yammer.com/images/no_photo_small.gif</mugshot-url> <previous-companies/> <birth-date></birth-date> <name>alice</name> <web-url>https://www.yammer.com/domain.com/users/alice</web-url> <interests nil="true"></interests> <state>active</state> <external-urls/> <url>https://www.yammer.com/api/v1/users/1089943</url> <network-domains> <network-domain>domain.com</network-domain> </network-domains> <id>1089943</id> <schools/> <hire-date nil="true"></hire-date> <significant-other nil="true"></significant-other> </response> <response> <contact> <phone-numbers/> <im> <provider></provider> <username></username> </im> <email-addresses> <email-address> <type>primary</type> <address>[email protected]</address> </email-address> </email-addresses> </contact> <job-title>Office Manager</job-title> <type>user</type> <expertise nil="true"></expertise> <summary nil="true"></summary> <kids-names nil="true"></kids-names> <location nil="true"></location> <guid nil="true"></guid> <timezone>Eastern Time (US &amp; Canada)</timezone> <network-name>Domain</network-name> <full-name>Bill</full-name> <network-id>79629</network-id> <stats> <followers>3</followers> <updates>1</updates> <following>1</following> </stats> <mugshot-url> https://assets3.yammer.com/images/no_photo_small.gif</mugshot-url> <previous-companies/> <birth-date></birth-date> <name>bill</name> <web-url>https://www.yammer.com/domain.com/users/bill</web-url> <interests nil="true"></interests> <state>active</state> <external-urls/> <url>https://www.yammer.com/api/v1/users/1089920</url> <network-domains> <network-domain>domain.com</network-domain> </network-domains> <id>1089920</id> <schools/> <hire-date nil="true"></hire-date> <significant-other nil="true"></significant-other> </response> </response>

• My App crashes when launched on my Iphone

• questions regarding the use of A* with the 15-square puzzle

  - by Cheeso

  I'm trying to build an A* solver for a 15-square puzzle. The goal is to re-arrange the tiles so that they appear in their natural positions. You can only slide one tile at a time. Each possible state of the puzzle is a node in the search graph. For the h(x) function, I am using an aggregate sum, across all tiles, of the tile's dislocation from the goal state. In the above image, the 5 is at location 0,0, and it belongs at location 1,0, therefore it contributes 1 to the h(x) function. The next tile is the 11, located at 0,1, and belongs at 2,2, therefore it contributes 3 to h(x). And so on. EDIT: I now understand this is what they call "Manhattan distance", or "taxicab distance". I have been using a step count for g(x). In my implementation, for any node in the state graph, g is just +1 from the prior node's g. To find successive nodes, I just examine where I can possibly move the "hole" in the puzzle. There are 3 neighbors for the puzzle state (aka node) that is displayed: the hole can move north, west, or east. My A* search sometimes converges to a solution in 20s, sometimes 180s, and sometimes doesn't converge at all (waited 10 mins or more). I think h is reasonable. I'm wondering if I've modeled g properly. In other words, is it possible that my A* function is reaching a node in the graph via a path that is not the shortest path? Maybe have I not waited long enough? Maybe 10 minutes is not long enough? For a fully random arrangement, (assuming no parity problems), What is the average number of permutations an A* solution will examine? (please show the math) I'm going to look for logic errors in my code, but in the meantime, Any tips? (ps: it's done in Javascript). Also, no, this isn't CompSci homework. It's just a personal exploration thing. I'm just trying to learn Javascript. EDIT: I've found that the run-time is highly depend upon the heuristic. I saw the 10x factor applied to the heuristic from the article someone mentioned, and it made me wonder - why 10x? Why linear? Because this is done in javascript, I could modify the code to dynamically update an html table with the node currently being considered. This allowd me to peek at the algorithm as it was progressing. With a regular taxicab distance heuristic, I watched as it failed to converge. There were 5's and 12's in the top row, and they kept hanging around. I'd see 1,2,3,4 creep into the top row, but then they'd drop out, and other numbers would move up there. What I was hoping to see was 1,2,3,4 sort of creeping up to the top, and then staying there. I thought to myself - this is not the way I solve this personally. Doing this manually, I solve the top row, then the 2ne row, then the 3rd and 4th rows sort of concurrently. So I tweaked the h(x) function to more heavily weight the higher rows and the "lefter" columns. The result was that the A* converged much more quickly. It now runs in 3 minutes instead of "indefinitely". With the "peek" I talked about, I can see the smaller numbers creep up to the higher rows and stay there. Not only does this seem like the right thing, it runs much faster. I'm in the process of trying a bunch of variations. It seems pretty clear that A* runtime is very sensitive to the heuristic. Currently the best heuristic I've found uses the summation of dislocation * ((4-i) + (4-j)) where i and j are the row and column, and dislocation is the taxicab distance. One interesting part of the result I got: with a particular heuristic I find a path very quickly, but it is obviously not the shortest path. I think this is because I am weighting the heuristic. In one case I got a path of 178 steps in 10s. My own manual effort produce a solution in 87 moves. (much more than 10s). More investigation warranted. So the result is I am seeing it converge must faster, and the path is definitely not the shortest. I have to think about this more. Code: var stop = false; function Astar(start, goal, callback) { // start and goal are nodes in the graph, represented by // an array of 16 ints. The goal is: [1,2,3,...14,15,0] // Zero represents the hole. // callback is a method to call when finished. This runs a long time, // therefore we need to use setTimeout() to break it up, to avoid // the browser warning like "Stop running this script?" // g is the actual distance traveled from initial node to current node. // h is the heuristic estimate of distance from current to goal. stop = false; start.g = start.dontgo = 0; // calcHeuristic inserts an .h member into the array calcHeuristicDistance(start); // start the stack with one element var closed = []; // set of nodes already evaluated. var open = [ start ]; // set of nodes to evaluate (start with initial node) var iteration = function() { if (open.length==0) { // no more nodes. Fail. callback(null); return; } var current = open.shift(); // get highest priority node // update the browser with a table representation of the // node being evaluated $("#solution").html(stateToString(current)); // check solution returns true if current == goal if (checkSolution(current,goal)) { // reconstructPath just records the position of the hole // through each node var path= reconstructPath(start,current); callback(path); return; } closed.push(current); // get the set of neighbors. This is 3 or fewer nodes. // (nextStates is optimized to NOT turn directly back on itself) var neighbors = nextStates(current, goal); for (var i=0; i<neighbors.length; i++) { var n = neighbors[i]; // skip this one if we've already visited it if (closed.containsNode(n)) continue; // .g, .h, and .previous get assigned implicitly when // calculating neighbors. n.g is nothing more than // current.g+1 ; // add to the open list if (!open.containsNode(n)) { // slot into the list, in priority order (minimum f first) open.priorityPush(n); n.previous = current; } } if (stop) { callback(null); return; } setTimeout(iteration, 1); }; // kick off the first iteration iteration(); return null; }
