• Strange HtmlUnit behavior (bug?)

  - by roddik

  Hello. Take a look at this: WebClient client = new WebClient(); WebRequestSettings wrs = new WebRequestSettings(new URL("http://stackoverflow.com/ping/?what-the-duck?"), HttpMethod.HEAD); client.getPage(wrs); Running this code results in throwing FileNotFoundException, because HTTP Status code on the page is 404 and getting the same page again with the GET method, with User-Agent set to Java-.... Why does it GET the page (it doesn't happen with "normal" status codes)? Is this a bug? Thanks Here is the entire server response: HTTP/1.1 404 Not Found Cache-Control: private Content-Length: 7502 Content-Type: text/html; charset=utf-8 Server: Microsoft-IIS/7.5 Date: Thu, 11 Feb 2010 14:12:11 GMT Where does it tell client to GET something? And how can I force WebClient to ignore it? Here's a screenshot of HTTPDebugger: The problem here is I don't understand why the second request is being sent and why is it sent with different useragent.

• coin rotation, as3

  - by VideoDnd

  What's the best way to make a coin rotation? I tried Math.random, but the coin doesn't wobble correctly. starter code //ROTATION addEventListener(Event.ENTER_FRAME, enterFrameHandler); function enterFrameHandler(event:Event):void { /* ADD VELOCITY, GRAVITY, ACCELERATION */ coin.rotationY += 8; } tried this, but it has no gravity or accelleration //ROTATION AND RANDOM MATH function wobble():void { var wobble = ((Math.random()*4)-2); flk.rotationY -= 11+wobble/2; flk.rotationX -= 2+wobble/20; } var myInterval:uint = setInterval (wobble, 40); I took out the work physics from my title:) I want it to behave like its affected by velocity, gravity, and acceleration.

• tmux: Suddenly, cannot horizontally split

  - by A__A__0

  As root, using a reasonably default .profile and .shrc and an empty tmux.conf, I am unable to split the window horizontally. There are a number of cases to consider so I'll list them clearly. Using the keybinding + empty configuration: nothing happens Using the keybinding + my configuration: a bell is generated, nothing else; occasionally, the split will appear and disappear immediately (maybe it always does this, but I'm connecting over ssh so it may not make it through) Using tmux split-window -h with any config: tmux immediately exits I've posted here in order the server and client verbose logs generated by tmux -v during the third case: server started, pid 9523 socket path /tmp/tmux-0/default new client 7 got 100 from client 7 got 101 from client 7 got 102 from client 7

(This happened for example when I ran ktrace on tmux, which I can also post) To explain the 'suddenly' part of the title: when I started my newly updated mysql56-server, tmux immediately exited and lost the session. Recently I changed architectures, from FreeBSD 10.0 i386 to amd64, and I am still working through shared library incompatibilities. I suspect that this could be involved, but I can't imagine how an incompatibility of this sort could result in such a specific, isolated failure.

• Strlen of MAX 16 chars string using bitwise operators

  - by fabrizioM

  The challenge is to find the fastest way to determine in C/C++ the length of a c-string using bitwise operations in C. char thestring[16]; The c-string has a max size of 16 chars and is inside a buffer If the string is equal to 16 chars doesn't have the null byte at the end. I am sure can be done but didn't got it right yet. I am working on this at the moment, but assuming the string is memcpied on a zero-filled buffer. len = buff[0] != 0x0 + buff[1] != 0x0 + buff[2] != 0x0 + buff[3] != 0x0 + buff[4] != 0x0 + buff[5] != 0x0 + buff[6] != 0x0 + buff[7] != 0x0 + buff[8] != 0x0 + buff[9] != 0x0 + buff[10] != 0x0 + buff[11] != 0x0 + buff[12] != 0x0 + buff[13] != 0x0 + buff[14] != 0x0 + buff[15] != 0x0;

• How can I get FreeNAS to respond to libvirt shutdown requests

  I have a KVM VM of FreeNAS 0.7.1 Shere (revision 5127) running on Ubuntu Server 10.04 and I'm unable to convince the VM to shutdown from the host virsh shutdown freenas I would expect this to send some ACPI? trigger to the VM and FreeNAS then do what it's told. I'm not a FreeBSD fundi so I don't really know what packages or processes to poke to get this running.

• Sequel Migration not running up?

  - by Sleepycat

  Having some trouble with the Migrations in Sequel and could use another set of eyes. I am running a migration that looks ok but no table is created. It is definitely connecting because I can see the schema_info table has been created. -M 0/1 changes the version as you would expect but still no table. The command: sequel -m . -M 1 ~/Desktop/dbtest/testdb.yml 001_testdb.rb: class TestDb < Sequel::Migration def up create_table( "terminals") do primary_key :id Integer :location_id Integer :merchant_id BigDecimal :terminal_id, :size=>[11, 0] String :reference, :size=>255 DateTime :created_at DateTime :updated_at String :image, :default=>"default.jpg", :size=>255 end end def down drop_table :terminals end end The output in Postgres: test_db=# \dt List of relations Schema | Name | Type | Owner --------+-------------+-------+---------- public | schema_info | table | postgres (1 row) test_db=# select * from schema_info; version --------- 1 (1 row)

• SQL: How do I return zeroes where there is nothing to aggregate across?

  - by Karl

  Hi What I would like ask is best illustrated by an example, so bear with me. Suppose I have the following table: TypeID Gender Count 1 M 10 1 F 3 1 F 6 3 M 11 3 M 8 I would like to aggregate this for every possible combination of TypeID and Gender. Where TypeID can be 1,2 or 3 and Gender can be M or F. So what I want is the following: TypeID Gender SUM(Count) 1 M 10 1 F 9 2 M 0 2 F 0 3 M 19 3 F 0 I can think of a few ways to potentially do this, but none of them seem particularly elegant to me. Any suggestions would be greatly appreciated! Karl

• Pylons 1.0 AttributeError: 'module' object has no attribute 'metadata'

  - by shiki

  Python noob trying to learn Pylons. I'm using the QuickWiki tutorial (http://pylonshq.com/docs/en/1.0/tutorials/quickwiki_tutorial/) from the 1.0 documentation, but this alleged "1.0" doc seems to just be "0.9.7"; I suspect that this has something to do with the error I'm getting. When I execute "paster setup-app development.ini", I get this: (mydevenv)lucid@lucid-laptop:~/QuickWiki$ paster setup-app development.ini Traceback (most recent call last): ... edited for brevity...

• Whats up with cross site Scripting (getJSON) and flickr example

  - by Bernhard

  In past i had read the documentation about getJSON and there is an example with a flickr photo api. (the example with the [pussy]cats :-)). No I ask myself why is it possible, to access flickr directly with this example. Ive tried this by store this code on my local machine - it works but if I use a local copy of jquery i just get an error in firebug like this $ is not defined myurl/test.html Line 11 Does anybody of you have a solution for this paradox thing? This is the documentation url HTTP:api.jquery.com/jQuery.getJSON/ The example isn´t also not working if I store the HTTP:code.jquery.com/jquery-latest.js in my local jquery file. I also dont understand why the request isnt´s visible in Firebug Console Thank you in advance Bernhard

• OpenSSH does not accept public key?

  - by Bob

  I've been trying to solve this for a while, but I'm admittedly quite stumped. I just started up a new server and was setting up OpenSSH to use key-based SSH logins, but I've run into quite a dilemma. All the guides are relatively similar, and I was following them closely (despite having done this once before). I triple checked my work to see if I would notice some obvious screw up - but nothing is apparent. As far as I can tell, I haven't done anything wrong (and I've checked very closely). If it's any help, on my end I'm using Cygwin and the server is running Ubuntu 12.04.1 LTS. Anyways, here is the output (I've removed/censored some parts for privacy (primarily anything with my name, website, or its IP address), but I can assure you that nothing is wrong there): $ ssh user@host -v OpenSSH_5.9p1, OpenSSL 0.9.8r 8 Feb 2011 debug1: Connecting to host [ipaddress] port 22. debug1: Connection established. debug1: identity file /home/user/.ssh/id_rsa type 1 debug1: identity file /home/user/.ssh/id_rsa-cert type -1 debug1: identity file /home/user/.ssh/id_dsa type -1 debug1: identity file /home/user/.ssh/id_dsa-cert type -1 debug1: identity file /home/user/.ssh/id_ecdsa type -1 debug1: identity file /home/user/.ssh/id_ecdsa-cert type -1 debug1: Remote protocol version 2.0, remote software version OpenSSH_5.9p1 Debian-5ubuntu1 debug1: match: OpenSSH_5.9p1 Debian-5ubuntu1 pat OpenSSH* debug1: Enabling compatibility mode for protocol 2.0 debug1: Local version string SSH-2.0-OpenSSH_5.9 debug1: SSH2_MSG_KEXINIT sent debug1: SSH2_MSG_KEXINIT received debug1: kex: server->client aes128-ctr hmac-md5 none debug1: kex: client->server aes128-ctr hmac-md5 none debug1: sending SSH2_MSG_KEX_ECDH_INIT debug1: expecting SSH2_MSG_KEX_ECDH_REPLY debug1: Server host key: ECDSA 24:68:c3:d8:13:f8:61:94:f2:95:34:d1:e2:6d:e7:d7 debug1: Host 'host' is known and matches the ECDSA host key. debug1: Found key in /home/user/.ssh/known_hosts:2 debug1: ssh_ecdsa_verify: signature correct debug1: SSH2_MSG_NEWKEYS sent debug1: expecting SSH2_MSG_NEWKEYS debug1: SSH2_MSG_NEWKEYS received debug1: Roaming not allowed by server debug1: SSH2_MSG_SERVICE_REQUEST sent debug1: SSH2_MSG_SERVICE_ACCEPT received debug1: Authentications that can continue: publickey debug1: Next authentication method: publickey debug1: Offering RSA public key: /home/user/.ssh/id_rsa debug1: Authentications that can continue: publickey debug1: Trying private key: /home/user/.ssh/id_dsa debug1: Trying private key: /home/user/.ssh/id_ecdsa debug1: No more authentication methods to try.

• Apache and MySQL taking all the memory? Maximum connections?

  - by lpfavreau

  I've a had one of our servers going down (network wise) but keeping its uptime (so looks the server is not losing its power) recently. I've asked my hosting company to investigate and I've been told, after investigation, that Apache and MySQL were at all time using 80% of the memory and peaking at 95% and that I might be needing to add some more RAM to the server. One of their justifications to adding more RAM was that I was using the default max connections setting (125 for MySQL and 150 for Apache) and that for handling those 150 simultaneous connections, I would need at least 3Gb of memory instead of the 1Gb I have at the moment. Now, I understand that tweaking the max connections might be better than me leaving the default setting although I didn't feel it was a concern at the moment, having had servers with the same configuration handle more traffic than the current 1 or 2 visitors before the lunch, telling myself I'd tweak it depending on the visits pattern later. I've also always known Apache was more memory hungry under default settings than its competitor such as nginx and lighttpd. Nonetheless, looking at the stats of my machine, I'm trying to see how my hosting company got those numbers. I'm getting: # free -m total used free shared buffers cached Mem: 1000 944 56 0 148 725 -/+ buffers/cache: 71 929 Swap: 1953 0 1953 Which I guess means that yes, the server is reserving around 95% of its memory at the moment but I also thought it meant that only 71 out of the 1000 total were really used by the applications at the moment looking a the buffers/cache row. Also I don't see any swapping: # vmstat 60 procs -----------memory---------- ---swap-- -----io---- -system-- ----cpu---- r b swpd free buff cache si so bi bo in cs us sy id wa 0 0 0 57612 151704 742596 0 0 1 1 3 11 0 0 100 0 0 0 0 57604 151704 742596 0 0 0 1 1 24 0 0 100 0 0 0 0 57604 151704 742596 0 0 0 2 1 18 0 0 100 0 0 0 0 57604 151704 742596 0 0 0 0 1 13 0 0 100 0 And finally, while requesting a page: top - 08:33:19 up 3 days, 13:11, 2 users, load average: 0.06, 0.02, 0.00 Tasks: 81 total, 1 running, 80 sleeping, 0 stopped, 0 zombie Cpu(s): 1.3%us, 0.3%sy, 0.0%ni, 98.3%id, 0.0%wa, 0.0%hi, 0.0%si, 0.0%st Mem: 1024616k total, 976744k used, 47872k free, 151716k buffers Swap: 2000052k total, 0k used, 2000052k free, 742596k cached PID USER PR NI VIRT RES SHR S %CPU %MEM TIME+ COMMAND 24914 www-data 20 0 26296 8640 3724 S 2 0.8 0:00.06 apache2 23785 mysql 20 0 125m 18m 5268 S 1 1.9 0:04.54 mysqld 24491 www-data 20 0 25828 7488 3180 S 1 0.7 0:00.02 apache2 1 root 20 0 2844 1688 544 S 0 0.2 0:01.30 init ...

• How do I.. get a value for time at 9:00am local, regardless of the timezone?

  - by ander163

  In my app, I need to set a variable for a start time to be 9:00 a.m. local, wherever the user is located. I have a timezone variable for each user and the save and retrieve are all working. But I need to set a variable when I create a new event to be 9:00 am in the user's local time zone. My current method uses the local time of the server, then makes the adjustments for the individual user's time zone. I don't know what I don't know - is there a command to create the value for "Today's date at 9:00 am where you are"? My current code is: t = Time.now.to_date.beginning_of_day + 11.hours (forcing the 2 hour offset between my primary user and the server in a different timezone).

• How to set an array to a list of values in VB.NET?

  - by IPX Ares

  I cannot figure out how to set an array to one of two sets of numbers (there will be more later), every way that I have tried throws some kind of error. I have tried to Dim the array inside the case statements, but then I cannot use the array in the For Each, which makes this worthless.... any ideas would be appreciated. Code: Dim HourArray() As Integer Select Case CurrentShapeRow(ROW_PERIOD) Case "ON", "2X16" HourArray = {6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21} Case "2X8", "5X8" HourArray = {0, 1, 2, 3, 4, 5, 22, 23} Case Else Throw New Exception(String.Format("Unhandled Period: {0}", CurrentShapeRow(ROW_PERIOD))) End Select For Each HourCount As Integer In HourArray() 'DO SOME STUFF HERE Next

• Rake don't know how to build task?

  - by Schroedinger

  Using a rake task to import data into a database: file as follows namespace :db do desc "load imported data from csv" task :load_csv_data => :environment do require 'fastercsv' require 'chronic' FasterCSV.foreach("input.csv", :headers => true) do |row| Trade.create( :name => row[0], :type => row[4], :price => row[6].to_f, :volume => row[7].to_i, :bidprice => row[10].to_f, :bidsize => row[11].to_i, :askprice => row[14].to_f, :asksize => row[15].to_i ) end end end When attempting to use this, with the right CSV files and the other elements in place, it will say Don't know how to build task 'db:import_csv_data' I know this structure works because I've tested it, I'm just trying to get it to convert to the new values on the fly. Suggestions?

• Doctrine Mssql uniqueidentifier isn't cast as char or nvarchar when retrieved from the database.

  - by Tres

  When I retrieve a record from the database which has a column of type "uniqueidentifier", Doctrine fills it with "null" rather than the unique id from the database. Some research and testing has brought this down to a PDO/dblib driver issue. When directly querying via PDO, null is returned in place of the unique id. For reference, http://trac.doctrine-project.org/ticket/1096, has a bit on this, however, it was updated 11 months ago with no comment for resolution. A way around this, as mentioned at http://bugs.php.net/bug.php?id=24752&edit=1, is to cast the column as a char. However, it doesn't seem Doctrine exposes the native field type outside of generating models which makes it a bit hard to detect uniqueidentifier types and cast them internally when building the sql query. Has anyone found a workaround for this?

• What Determines the Default Setting of the x87 FPU Control Word?

  - by Rick Regan

  What determines the default setting of the x87 FPU control word -- specifically, the precision control field? Does the compiler set it based on the target processor? Is there a compiler option to change it? Using Microsoft Visual C++ 2008 Express Edition on an Intel Core Duo processor, the default setting for the precision control field is "01b", meaning double (53 bit) precision. I'm wondering -- why is the default not "11"b, or extended (64 bit) precision? (I know I can change it using _controlfp.)
