  • Python Parse regex

    - by Nemo
    Let's say I have string in the form given below: myString={"name", "age", "address", "contacts", "Email"} I need to get all the items of myString into a List using python. Here's what I did r= re.search("myString=\{\"(.+)\", $\}", line) if r: items.append(r.group(1)) print(items) Here line is the variable that holds the content of my text file. What change do I have to make to my regex to get all the items in myString? Please kindly help me out. Thanks.

  • Who likes short shorts?

    - by kiwicptn
    I got $2 change instead of $3 today and that got me thinking about short for some reason. What can do (these days ;-p) with a variable of the short primitive type (16 bits signed)? Any good reason to keep them around?

  • Python: Create a duplicate of an array

    - by Dan
    I have an double array alist[1][1]=-1 alist2=[] for x in xrange(10): alist2.append(alist[x]) alist2[1][1]=15 print alist[1][1] and I get 15. Clearly I'm passing a pointer rather than an actual variable... Is there an easy way to make a seperate double array (no shared pointers) without having to do a double for loop? Thanks, Dan

  • How to configure LAN IP Filter on Huawei E586 UMTS Modem

    - by Mose
    I need to prevent clients of an Huawei E586 UMTS to WiFi modem from downloading much data from specific servers eg. Windows update or OSX update. On the config page of the device there's an "LAN IP Filter" which seems pretty good but I can't figure out the right settings. The mask looks like this: The help pages states the following: My problem with this is, I want some wildcard for the local ip and port. In my opinion the help page can not be correct by "lan port: enter 80" because the source port is normally dynamic. I tried to set it up like stated there but as expected it doesn't work. As wildcards I tried * and "ALL" but nothing worked as it prevents me from saving settings with an "wrong value" error. Any suggestions? Thanks in advance!

  • Network - Routers conflicting in my subnet

    - by Richard
    I have a router whose IP is 192.168.1.1 and I be experiencing conflict with another router on my subnet (which probably has 192.168.1.1 as IP too). I think when it tries to connect to the network, eventually taking the place of my router because when I try to access the config page of my router, which appears to me is a config page from another router that is not mine. Do you have any solution except to change the IP of my router to an IP not common? As I have set up the exclusivity that only my IP router? I work with dynamic IPs (wireless networking) and static (for wired). How do I? I just wanna to do some setting in my router that affects all other, so that doesn't conflicts anymore.

  • Need helping creating a loop in R. Have many similarly named variables I have to apply the same func

    - by user335897
    I am using a dataset w/variables that have very similar names.

  • Card game in python

    - by matt1024
    What is the best way to store the cards and suits in python so that I can hold a reference to these values in another variable? For example, if I have a list called hand (cards in players hand), how could I hold values that could refer to the names of suits and values of specific cards, and how would these names and values of suits and cards be stored?

  • Restoring factory image of HP Laptop

    - by Ahmed
    I use a HP G62. I am unable to use my recovery disk to restore to factory settings. I had no problems earlier until I created an additional partition which I hear might have changed my hard disk to dynamic. How do I get back to 'normal'? I don't mind formatting the disk. I just want my factory OS back. .............. i get an error message at about 69 percent telling me that the restoration process failed. I'm using the factory image disks i created using the hp recovery manager. I have tried formating the hard drive clean and then restoring woth the cd, it didn't work. I was always able to restore before i created that partition.

  • uWSGI and Nginx python file handling

    - by user133507
    I've been trying to figure out how to propertly utilize uWSGI with Nginx and have hit a bit of a design roadblock. I'm trying to figure out how my python files should be accessed via uWSGI. I've been able to find 3 different ways to do so: Create a uWSGI process for each python file and then create locations in nginx that pass to each uWSGI process. Create one instance of uWSGI and create a master python file that handles all the different requests. Create one instance of uWSGI and setup dynamic applications I'm coming from LightTPD where I simply setup rewrites to point at the different python files. I feel like 3 is the closest to that but uWSGI says that it is not the recommended way of going about it.

  • How to ignore expired certificates from outside a Java application?

    - by Creepy Gnome
    We have a Java application that we need to ignore an expired self-signed cert, however we cannot modify the code to do this. I wondering if there was a System Property or environment variable that we could provide at start up that would allow us to have all expired cert's ignored for now, or even be more specific and provide externally the specific cert that we would like to have the expiration ignored. Anyone have any ideas that would work?

  • What's the best way to structure this Linq-to-Events Drag & Drop code?

    - by Rob Fonseca-Ensor
    I am trying to handle a drag & drop interaction, which involves mouse down, mouse move, and mouse up. Here is a simplified repro of my solution that: on mouse down, creates an ellipse and adds it to a canvas on mouse move, repositions the ellipse to follow the mouse on mouse up, changes the colour of the canvas so that it's obvious which one you're dragging. var mouseDown = Observable.FromEvent<MouseButtonEventArgs>(canvas, "MouseLeftButtonDown"); var mouseUp = Observable.FromEvent<MouseButtonEventArgs>(canvas, "MouseLeftButtonUp"); var mouseMove = Observable.FromEvent<MouseEventArgs>(canvas, "MouseMove"); Ellipse ellipse = null; var q = from start in mouseDown.Do(x => { // handle mousedown by creating a red ellipse, // adding it to the canvas at the right position ellipse = new Ellipse() { Width = 10, Height = 10, Fill = Brushes.Red }; Point position = x.EventArgs.GetPosition(canvas); Canvas.SetLeft(ellipse, position.X); Canvas.SetTop(ellipse, position.Y); canvas.Children.Add(ellipse); }) from delta in mouseMove.Until(mouseUp.Do(x => { // handle mouse up by making the ellipse green ellipse.Fill = Brushes.Green; })) select delta; q.Subscribe(x => { // handle mouse move by repositioning ellipse Point position = x.EventArgs.GetPosition(canvas); Canvas.SetLeft(ellipse, position.X); Canvas.SetTop(ellipse, position.Y); }); the XAML is simply <Canvas x:Name="canvas"/> There's a few things I don't like about this code, and I need help refactoring it :) First of all: the mousedown and mouseup callbacks are specified as side effects. If two subscriptions are made to q, they will happen twice. Second, the mouseup callback is specified before the mousemove callback. This makes it a bit hard to read. Thirdly, the reference to the ellipse seems to be in a silly place. If there's two subscriptions, that variable reference will get overwritten quite quickly. I'm sure that there should be some way we can leverage the let keyword to introduce a variable to the linq expression that will mean the correct ellipse reference is available to both the mouse move and mouse up handlers How would you write this code?

  • Best practices for mass email platform

    - by Niro
    I am in the process of setting up mass email service. My question is: what are the best practices to achieve maximum deliver-ability. More precisely - what should I do/know to prevent spam filters from blocking the emails (the emails are not spam). for example- how can I tell if my IP address is blacklisted somewhere and how can I prevent it from becoming blacklisted. Is amazon web services a suitable platform due to dynamic IP addresses, what are the restrictions on the from address, can it be different from the mail server domain.... you get it....

  • In a bash script echo shell commands

    In a bash script how do I echo all shell commands called and expand any variable names? For example, given the following line: ls $DIRNAME I would like the script to run the command and display the following ls /full/path/to/some/dir The purpose is to save a log of all shell commands called and their arguments. Perhaps there is a better way of generating such a a log?

  • Understanding this error: apr_socket_recv: Connection reset by peer (104)

    - by matthewsteiner
    So, if I do some benchmarking with apache benchmark (ab), and I use large numbers of requests. Then sometimes in the middle of a test I get this error. I don't even know what it means. So how can I fix it? Or is it just something that will happen if the server gets too many hits anyway? The problem is, if I run 10,000 hits, it'll all run perfectly. If I run it again, it'll get to 4000 and get the error: apr_socket_recv: Connection reset by peer (104) A little about my setup: I have nginx taking static requests and processing dynamic ones to apache. The file in question is served from cache by nginx, so I guess it's probably got to do with how nginx is handling the requests? Ideas?

  • Fixing VBSCRIPT inaccurate mathematical results due to rounding

    - by jay
    Try running this in a .VBS file MsgBox(545.14-544.94) You get a neat little answer of 0.199999999999932! This rounding issue also occurs unfortunately in Sin(2 * pi) since VB can only ever see the (user defined) variable pi as accurate as 3.14159265358979. Is rounding it manually (and loosing accuracy) the only way to improve the result? What is the most effective way of dealing with this kind of problem?

    Hi, I installed Tomcat 6.0.18 on Windows 2003 as a service. I try to set the CATALINA_OPTS environment variable but it seems to be ignored by Tomcat. Do I need to use the Tomcat Service Manager (procrun) instead? Is it normal that if I install Tomcat as a service it doesn't see the enviroment variables but it only wotks with procrun? THANKS

  • Unicast traffic between hosts on a switch leaving the switch by its uplink. Why?

    - by Rich Lafferty
    I have a weird thing happening on our network at my office which I can't quite get my head around. In particular I can't tell if it's a problem with a switch, or a problem with configuration. We have a Cisco SG300-52 switch (sw01) in the top of a rack in our server room, connected to another SG300-28 that acts as our core switch (core01). Both run layer 2 only, our firewalls do routing between VLANs. They have a dozen or so VLANs between them. Gi1 on sw01 is a trunk port connected to gi1 on core01. (Disclosure: There are other switches in our environment but I'm pretty sure I've isolated the problem down to these two. Happy to provide more info if necessary.) The behaviour I'm seeing is limited to one VLAN, vlan 12 -- or, at least, it's not happening on the other ones I checked (It's hard to guarantee the absence of packets), and it is: sw01 is forwarding, to core01, traffic which is between two hosts which are both plugged into sw01. (I noticed this because the IDS in our firewall gave a false positive on traffic which should not reach the firewall.) We noticed this mostly between our two dhcp/dns servers, net01 (10.12.0.10) and net02 (10.12.0.11). net01 is physical hardware and net02 is on a VMware ESX server. net01 is connected to gi44 on sw01 and net02's ESX server to gi11. [net01]----gi44-[sw01]-gi1----gi1-[core01] [net02]----gi11/ Let's see some interfaces! Remember, vlan 12 is the problem vlan. Of the others I explicitly verified that vlan 27 was not affected. Here's the two hosts' ports: esx01 contains net02. sw01#sh run int gi11 interface gigabitethernet11 description esx01 lldp med disable switchport trunk allowed vlan add 5-7,11-13,100 switchport trunk native vlan 27 ! sw01#sh run int gi44 interface gigabitethernet44 description net01-1 lldp med disable switchport mode access switchport access vlan 12 ! Here's the trunk on sw01. sw01#sh run int gi1 interface gigabitethernet1 description "trunk to core01" lldp med disable switchport trunk allowed vlan add 4-7,11-13,27,100 ! And the other end of the trunk on core01. interface gigabitethernet1 description sw01 macro description switch switchport trunk allowed vlan add 2-7,11-16,27,100 ! I have a monitor port on core01, thus: core01#sh run int gi12 interface gigabitethernet12 description "monitor port" port monitor GigabitEthernet 1 ! And the monitor port on core01 sees unicast traffic going between net01 and net02, both of which are on sw01! I've verified this with a monitor port on sw01 that sees the net01-net02 unicast traffic leaving via gi1 too. sw01 knows that both of those hosts are on ports that are not its trunk port: :) ratchet$ arp -a | grep net net02.2ndsiteinc.com (10.12.0.11) at 00:0C:29:1A:66:15 [ether] on eth0 net01.2ndsiteinc.com (10.12.0.10) at 00:11:43:D8:9F:94 [ether] on eth0 sw01#sh mac addr addr 00:0C:29:1A:66:15 Aging time is 300 sec Vlan Mac Address Port Type -------- --------------------- ---------- ---------- 12 00:0c:29:1a:66:15 gi11 dynamic sw01#sh mac addr addr 00:11:43:D8:9F:94 Aging time is 300 sec Vlan Mac Address Port Type -------- --------------------- ---------- ---------- 12 00:11:43:d8:9f:94 gi44 dynamic I also brought up an unused port on sw01 on vlan 12, but the unicast traffic was (as best as I could tell) not coming out that port. So it doesn't look like sw01 is pushing it out all its ports, just the right ports and also gi1! I've verified that sw01 is not filling up its address-table: sw01#sh mac addr count This may take some time. Capacity : 8192 Free : 7983 Used : 208 The full configs for both core01 and sw01 are available: core01, sw01. Finally, versions: sw01#sh ver SW version 1.1.2.0 ( date 12-Nov-2011 time 23:34:26 ) Boot version 1.0.0.4 ( date 08-Apr-2010 time 16:37:57 ) HW version V01 core01#sh ver SW version 1.1.2.0 ( date 12-Nov-2011 time 23:34:26 ) Boot version 1.1.0.6 ( date 11-May-2011 time 18:31:00 ) HW version V01 So my understanding is this: sw01 should take unicast traffic for net01 and send it only out net02's port, and vice versa; none of it should go out sw01's uplink. But core01, receiving traffic on gi1 for a host it knows is on gi1, is right in sending it out all of its ports. (That is: sw01 is misbehaving, but core01 is doing what it should given the circumstances.) My question is: Why is sw01 sending that unicast traffic out its uplink, gi1? (And pre-emptively: yes, I know SG300s leave much to be desired, and yes, we should have spanning-tree enabled, but that's where I'm at right now.)
