  • Efficient way to organise data file in columns with Python

    - by user1700959
    I'm getting an output data file of a program which looks like this, with more than one line for each time step: 0.0000E+00 0.0000E+00 0.0000E+00 0.0000E+00 0.0000E+00 0.0000E+00 0.0000E+00 0.0000E+00 0.0000E+00 0.0000E+00 7.9819E-06 1.7724E-02 2.3383E-02 3.0048E-02 3.8603E-02 4.9581E-02 5.6635E-02 4.9991E-02 3.9052E-02 3.0399E-02 .... I want to arrange it in ten columns I have made a Python script, using regular expressions to delete \n in the proper lines, but I think that there should be a simpler more elegant way to do it, here is my script: import re with open('inputfile', encoding='utf-8') as file1: datai=file1.read() dataf=re.sub(r'(?P<nomb>( \d\.\d\d\d\dE.\d\d){8})\n','\g<nomb>',datai) with open('result.txt',mode='w',encoding='utf-8') as resultfile: resultfile.write(datof) Thanks in advance

  • Google CDN not gzipping jquery

    - by thermal7
    If I navigate here: http://ajax.microsoft.com/ajax/jquery/jquery-1.4.2.min.js I download 70k using Firefox 3.6.3 and I can confirm it is sending Accept-Encoding: gzip. If I use the Microsoft one: http://ajax.microsoft.com/ajax/jquery/jquery-1.4.2.min.js I download 30k (and it comes through as Content-Encoding: gzip) I am also experiencing this when using jquery 1.4.2 in regular sites eg jquery.com. Funily enough, stack overflow which references jquery 1.3.2 on the google cdn, is coming through gzipped. Why is this happening? Is it some kind of issue with google or am I missing something? I live in Melbourne, Australia.

  • Inconsistent Behavior From Declared DLL Function

    - by Steven
    Why might my GetRawData declared function return a correct value when called from my VB.NET application, but return zero when called from my ASP.NET page? The code is exactly the same except for class type difference (Form / Page) and calling event handler (Form1_Load, Page_Load). Note: In the actual code, #DLL# and #RAWDATAFILE# are both absolute filenames to my DLL and raw data file respectively. Note: The DLL file was not created by Visual Studio. Form1.vb Public Class Form1 Declare Auto Function GetRawData Lib "#DLL#" (ByVal filename() As Byte, _ ByVal byteArray() As Byte, _ ByVal length As Int32) As Int32 Private Sub Form1_Load(ByVal sender As System.Object, _ ByVal e As System.EventArgs) Handles MyBase.Load Dim buffer(10485760) As Byte Dim msg As String, length As Integer = 10485760 Dim filename As String = "#RAWDATAFILE#" length = GetRawData(Encoding.Default.GetBytes(filename), buffer, length) Default.aspx.vb Partial Public Class _Default Inherits System.Web.UI.Page Declare Auto Function GetRawData Lib "#DLL#" (ByVal filename() As Byte, _ ByVal byteArray() As Byte, _ ByVal length As Int32) As Int32 Protected Sub Page_Load(ByVal sender As Object, _ ByVal e As System.EventArgs) Handles Me.Load Dim buffer(10485760) As Byte Dim msg As String, length As Integer = 10485760 Dim filename As String = "#RAWDATAFILE#" length = GetRawData(Encoding.Default.GetBytes(filename), buffer, length)

  • sql server bulk copy out/postgres copy from infile

    - by Chris Curvey
    I'm starting a conversion of a system from MS SQL Server to Postgres. I have the table structures converted, and I use "bcp" to get the data out of SQL Server. ERROR: invalid byte sequence for encoding "UTF8": 0x80 HINT: This error can also happen if the byte sequence does not match the encoding expected by the server, which is controlled by "client_encoding". CONTEXT: COPY cm_outgoing, line 200: "200 c:\temp\200.xml 2009-10-10 01:50:44.000 1900-01-01 00:00:00.000" I've already used "sed" to get rid of the NUL (0x00) entries in the file, and I can't find any instances of 0x80 in the file that I'm trying to import. Any thoughts? Is there an easier way?

    I am using Propel as my DAL for my Symfony project. I can't seem to get my application to work across two or more databases.

  • How to replicate Google "Hangouts On Air" stream combining functionality?

    - by Rob Olmos
    I've been researching this one for quite a bit but haven't found any solid leads. I have a Wowza/Flash app with video chatroom functionality and would like to combine the streams server-side into one video/audio stream in order to be sent to a live Youtube channel. I've found a couple projects such as jMixer and some helpful keywords such as "vision mixer" to help with my search but looking for any previous experience or new ideas. The other option is building something like it myself with a commercial video decoding/encoding library to raw frames, stitching the frames together, then encoding it. I was originally going down this route but put project on hold. What are some ideas, keywords, or existing software (open source preferred) to take those live streams and combine them into one in real-time? Or is coding it myself the required route? Thanks!

  • Is the XML processing instructions node mandatory ?

    - by ereOn
    I had a discussion with a colleague of mine about the XML processing instructions node (I'm talking about this = <?xml version="1.0" encoding="UTF-8"?>). I believe that for something to be called "valid XML", it requires a processing instructions node. My colleague states that the processing instruction node is optionnal, since the default encoding is UTF-8 and the version is always 1.0. This make sense, but what does the standard says ? In short, given the following file: <books> <book id="1"><title>Title</title></book> </book> Can we say that: It is valid XML ? It is a valid XML node ? It is a valid XML document ? Thank you very much.

  • rake db:create not working for legacy rails app (2.3.5) using MySQL (5.5.28)

    - by ridicter
    I'm a new Rails Developer, and I'm working on a legacy Rails app. Whenever I run the rake db:create command, I get an error that the database couldn't be created. I have found many StackOverflow questions related to this, but in troubleshooting nearly all permutations of solutions, I couldn't resolve the issue. I created the three Dbs (dev, prod, test), created the user with all access privileges to these dbs, and ran rake db:create. I'm running Mac OS X Lion, MySQL 5.5.28, Rails 2.3.5, Ruby 1.8.7. Here are my settings development: adapter: mysql encoding: utf8 database: adva_development username: adva password: **** host: localhost socket: /tmp/mysql.sock Here's the error: Couldn't create database for {"adapter"=>"mysql", "username"=>"adva", "host"=>"localhost", "encoding"=>"utf8", "database"=>"adva_development", "socket"=>"/tmp/mysql.sock", "password"=>"****"}, charset: utf8, collation: utf8_unicode_ci (if you set the charset manually, make sure you have a matching collation) I have done the following troubleshooting: Verified user and password are correct, and the user has access to the DB. (Double checked user access with SELECT * FROM mysql.db WHERE Db = 'adva_development' \G; User has all privileges.) Verify the socket is correct. I don't really understand sockets, but I can plainly see it at /tmp/mysql.sock. Checked collation and character set. I found out I had created the DB in latin charset and collation, so I recreated them. I ran show variables like "collation_database"; and show variables like "character_set_database"; and came back with utf8 and utf8_unicode_ci respectively. I followed the instructions in this question. After uninstalling mysql gem, I ran the following but came up with the same error: gem install --no-rdoc --no-ri mysql -- --with-mysql-dir=/usr/local/mysql-5.5.28-osx10.6-x86_64/bin --with-mysql-config=/usr/local/mysql-5.5.28-osx10.6-x86_64/bin/mysql_config Following Matt's suggestion, here's what a rake --trace db:create reveals: ** Invoke db:create (first_time) ** Invoke db:load_config (first_time) ** Invoke rails_env (first_time) ** Execute rails_env ** Execute db:load_config ** Execute db:create Couldn't create database for {"database"=>"adva_development", "adapter"=>"mysql", "host"=>"127.0.0.1", "password"=>"woof2adva", "username"=>"adva", "encoding"=>"utf8"}, charset: utf8, collation: utf8_unicode_ci (if you set the charset manually, make sure you have a matching collation) After 3 days and six or seven hours, I have pretty much run out of options. I tried various random things, like replacing localhost with 127.0.0.1 to no avail. Could there be something wrong related to my specific environment? Mac OS X Lion + MySQL 5.5.28? I plan on trying on setting up everything in a Linux environment. Thanks!

  • Facebook iframe app redirecting https to http, how?

    - by Paul Whitrow
    I'm trying to get an app working within Facebook, but it seems that no matter what I try including forcing just https in the app settings (see screen shot), the iframe source (Facebooks canvas) seems to change the https address to http (301) which is then producing SEC7111: HTTPS security errors in IE?

  • Django Custom Field: Only run to_python() on values from DB?

    - by Adam Levy
    How can I ensure that my custom field's *to_python()* method is only called when the data in the field has been loaded from the DB? I'm trying to use a Custom Field to handle the Base64 Encoding/Decoding of a single model property. Everything appeared to be working correctly until I instantiated a new instance of the model and set this property with its plaintext value...at that point, Django tried to decode the field but failed because it was plaintext. The allure of the Custom Field implementation was that I thought I could handle 100% of the encoding/decoding logic there, so that no other part of my code ever needed to know about it. What am I doing wrong? (NOTE: This is just an example to illustrate my problem, I don't need advice on how I should or should not be using Base64 Encoding) def encode(value): return base64.b64encode(value) def decode(value): return base64.b64decode(value) class EncodedField(models.CharField): __metaclass__ = models.SubfieldBase def __init__(self, max_length, *args, **kwargs): super(EncodedField, self).__init__(*args, **kwargs) def get_prep_value(self, value): return encode(value) def to_python(self, value): return decode(value) class Person(models.Model): internal_id = EncodedField(max_length=32) ...and it breaks when I do this in the interactive shell. Why is it calling to_python() here? >>> from myapp.models import * >>> Person(internal_id="foo") Traceback (most recent call last): File "<console>", line 1, in <module> File "/usr/local/lib/python2.6/dist-packages/django/db/models/base.py", line 330, in __init__ setattr(self, field.attname, val) File "/usr/local/lib/python2.6/dist-packages/django/db/models/fields/subclassing.py", line 98, in __set__ obj.__dict__[self.field.name] = self.field.to_python(value) File "../myapp/models.py", line 87, in to_python return decode(value) File "../myapp/models.py", line 74, in decode return base64.b64decode(value) File "/usr/lib/python2.6/base64.py", line 76, in b64decode raise TypeError(msg) TypeError: Incorrect padding I had expected I would be able to do something like this... >>> from myapp.models import * >>> obj = Person(internal_id="foo") >>> obj.internal_id 'foo' >>> obj.save() >>> newObj = Person.objects.get(internal_id="foo") >>> newObj.internal_id 'foo' >>> newObj.internal_id = "bar" >>> newObj.internal_id 'bar' >>> newObj.save() ...what am I doing wrong?

  • C++ Static Array Initialization - Memory Issue

    - by donalmg
    Hi, I have a header file which contains a member variable declaration of a static char array: class ABC { public: static char newArray[4]; // other variables / functions private: void setArray(int i, char * ptr); } In the CPP file, I have the array initialized to NULL: char ABC::newArray[4] = {0}; In the ABC constructor, I need to overwrite this value with a value constructed at runtime, such as the encoding of an integer: ABC::ABC() { int i; //some int value defined at runtime memset(newArray, 0, 4); // not sure if this is necessary setArray(i,newArray); } ... void setArray(int i, char * value) { // encoding i to set value[0] ... value [3] } When I return from this function, and print the modified newArray value, it prints out many more characters than the 4 specified in the array declaration. Any ideas why this is the case. I just want to set the char array to 4 characters and nothing further. Thanks...

  • Creating a json obj from a string when working without a net connection?

    - by user246114
    Hi, I have a json object returned from a third party api, it looks like: {"version":"1.0","encoding":"UTF-8"} I'm going to be working on my project without a network connection, so I have to do everything locally. How can I create an instance of a json object locally for testing? Say I copy the above string, can I do something like: var json = null; if (debugging_locally) { json = new jsonObj('{"version":"1.0","encoding":"UTF-8"}'); } else { json = doAjaxCall(); } doStuffWithJsonObj(json); so I just want to create a json object from a stored string if debugging locally - how can I do that?

  • c# unicode string output

    - by Reg
    I have function to convert string to a Unicode string: private string UnicodeString(string text) { return Encoding.UTF8.GetString(Encoding.ASCII.GetBytes(text)); } But when I am calling this function the output result is wrong. It looks like my function is not working. Console.WriteLine(UnicodeString("????? ?????")) printing on console just questions like that: ????? ???? Is there any way to say to console to display it correct? UPDATE Looks like the problem not in Unicode, I think may be it is displaying question marks because i am not having correct locale in the system (Windows 7)? Is there any way to make it work without changing locale?

  • communicate with a process in utf-8 on a cp1252 consoless

    - by Mapad
    I need to control a program by sending commands in utf-8 encoding to its standard input. For this I run the program using subprocess.Popen(): proc = Popen("myexecutable.exe", shell=True, stdin=PIPE, stdout=PIPE, stderr=PIPE) proc.stdin.write(u'ééé'.encode('utf_8')) If I run this from a cygwin utf-8 console, it works. If I run it from a windows console (encoding ='cp1252') this doesn't work. Is there a way to make this work without having to install a cygwin utf-8 console on each computer I want it to run from ? (NB: I don't need to output anything to console)

  • Installing gitosis and closed port?

    - by Nicolas GUILLAUME
    I'm trying to install gitosis on a Server (hosted by OVH and running Ubuntu server 11.04). I've done it a few times and never had any problems. But this time I have something very wired when I simply try to clone gitosis. [root@ovks-1:~/]#git clone git://eagain.net/gitosis.git Cloning into gitosis... eagain.net[0: 208.78.102.120]: errno=Connection refused fatal: unable to connect a socket (Connection refused) zsh: exit 128 git clone git://eagain.net/gitosis.git Based on my searches it looks like the port 9418 is closed. But I don't understand, a server by definition shouldn't have any closed port and I can't find a way to see if they are. So how can I check is a port is open and how can I open it if closed? Thank you for your help. Requested by WesleyDavid: iptables -L result [root@odeoos-vks-1:~/]#iptables -L Chain INPUT (policy ACCEPT) target prot opt source destination Chain FORWARD (policy ACCEPT) target prot opt source destination Chain OUTPUT (policy ACCEPT) target prot opt source destination I have no idea what it means...

  • iSCSI errors continue after removing inaccessible target portal

    - by Ansgar Wiechers
    By mistake I entered an iSCSI target portal address in the iSCSI Initiator on one of our virtual servers that does not have an address in the network range used for iSCSI. This caused the following errors/warnings to appear in the eventlog: Log Name: System Source: MSiSCSI Event ID: 113 Level: Warning Description: iSCSI discovery via SendTargets failed with error code 0xefff0003 to target portal *192.168.23.42 0003260 Root\ISCSIPRT\0000_0 . Log Name: System Source: iScsiPrt Event ID: 1 Level: Error Description: Initiator failed to connect to the target. Target IP address and TCP Port number are given in dump data. Log Name: System Source: iScsiPrt Event ID: 70 Level: Error Description: Error occurred when processing iSCSI logon request. The request was not retried. Error status is given in the dump data. So far that's expected beahvior, so I removed the portal from the iSCSI Initiator as described in MSKB 976072. However, the errors/warnings keep appearing every hour, even though neither iSCSI Initiator GUI nor iscscli show any portals: C:\>iscsicli ListTargetPortals Microsoft iSCSI Initiator Version 6.1 Build 7601 The operation completed successfully. The problem persists after rebooting the server. Uninstalling the Microsoft iSCSI Initiator device via devmgmt.msc as well as changing the Initiator parameters like this: [HKLM\SYSTEM\CurrentControlSet\Control\Class\{4D36E97B-E325-11CE-BFC1-08002BE10318}] "MaxPendingRequests"=dword:00000001 "MaxConnectionRetries"=dword:00000001 "MaxRequestHoldTime"=dword:00000005 didn't help either. Each change was followed by a reboot. Disabling the device does prevent the errors/warnings from re-appearing, of course, but I'd rather not have to resort to this. How can I prevent those errors and warnings from appearing (short of disabling the initiator device or re-installing the server)? What am I missing? Environment: The virtual machine runs on a Hyper-V cluster managed by SCVMM 2012. Hosts and guests run Windows Server 2008 R2 SP1. The physical machines are Dell PowerEdge M710HD blades.

  • Zabbix Proxy not collecting data

    - by Jordan Eunson
    I have a working Zabbix 1.8.2 server collecting data for our office and our colo facility. However the link between the colo and office is flaky. What I'm trying to do is setup a proxy on the colo side to have a 1 hour cache and relay the data to our primary server at the office. Our zabbix server is compiled from source and uses a mysql database I've followed the instructions found in the zabbix documentation to compile the proxy using a sqlite3 database. I add the proxy to zabbix under Administration-DM-Proxies. The zabbix server "sees" the proxy because the "last seen" field is always under 60s. However when I assign a colo host to the proxy I stop receiving data from it. The colo host's zabbix_agentd.log file says this: 29343:20100622:124847 Timeout while answering request 29343:20100622:124847 Getting list of active checks failed. Will retry after 60 seconds The zabbix_proxy.log says this. 2041:20100622:123131.760 Deleted 0 records from history [0.000994 seconds] 2028:20100622:124131.671 Error while receiving answer from server [ZBX_TCP_READ() failed I also am unable to receive any SNMP data which is more important to me than the zabbix agent data. Has anyone had this problem before? Zabbix Server OS: CentOS5.4 Zabbix Server Build: 1.8.2 from source Zabbix Proxy OS: CentOS5.4 Zabbix Proxy Build: 1.8.2 from source P.S. The SQLite database on the zabbix proxy never gets any data written to it, it is identical to when I created it from the blank schema in zabbix-1.8.2/create/schema.

  • Why are UDP messages from outside the network received but not delivered?

    - by Warren Pena
    I have an Ubuntu Server 10.04 application I've developed that receives messages over a UDP port. The ultimate purpose of this application is to receive messages sent from workers' 3G modems out in the field. If use netcat on either another ubuntu Server or my Vista laptop (both on the same LAN as my test machine) to send a message, the message arrives correctly and appears in my application. However, if I go out to my car and use its 3G modem to send a message from the same Vista laptop, it doesn't work. If I run tcpdump -A, I see the message arrive correctly, but it's never delivered to my application. Clearly, the OS is the one making the choice not to deliver the messages (else they wouldn't appear in tcpdump nor would my app receive them when coming from local machines). I have not installed any firewall software on this machine, nor am I aware of anything installed by default that would block the traffic. sudo iptables --list returns Chain INPUT (policy ACCEPT) target prot opt source destination Chain FORWARD (policy ACCEPT) target prot opt source destination Chain OUTPUT (policy ACCEPT) target prot opt source destination I'm not too familiar with iptables, but it looks to me like that's telling it to not do anything. What could be going on that's preventing my messages from being delivered?

  • Configuration management in support of scientific computing

    - by Sharpie
    For the past few years I have been involved with developing and maintaining a system for forecasting near-shore waves. Our team has just received a significant grant for further development and as a result we are taking the opportunity to refactor many components of the old system. We will also be receiving a new server to run the model and so I am taking this opportunity to consider how we set up the system. Basically, the steps that need to happen are: Some standard packages and libraries such as compilers and databases need to be downloaded and installed. Some custom scientific models need to be downloaded and compiled from source as they are not commonly provided as packages. New users need to be created to manage the databases and run the models. A suite of scripts that manage model-database interaction needs to be checked out from source code control and installed. Crontabs need to be set up to run the scripts at regular intervals in order to generate forecasts. I have been pondering applying tools such as Puppet, Capistrano or Fabric to automate the above steps. It seems perfectly possible to implement most of the above functionality except there are a couple usage cases that I am wondering about: During my preliminary research, I have found few examples and little discussion on how to use these systems to abstract and automate the process of building custom components from source. We may have to deploy on machines that are isolated from the Internet- i.e. all configuration and set up files will have to come in on a USB key that can be inserted into a terminal that can connect to the server that will run the models. I see this as an opportunity to learn a new tool that will help me automate my workflow, but I am unsure which tool I should start with. If any member of the community could suggest a tool that would support the above workflow and the issues specific to scientific computing, I would be very grateful. Our production server will be running Linux, but support for OS X would be a bonus as it would allow the development team to setup test installations outside of VirtualBox.
