  • Add entry to list and remove first one in Python

    - by wagglewax
    I have a list of about 40 entries. And I frequently want to append an item to the start of the list (with id 0) and want to delete the last entry (with id 40) of the list. how do i do this the best? like: (example with 5 entries) [0] = "herp" [1] = "derp" [2] = "blah" [3] = "what" [4] = "da..." after adding "wuggah" and deleting last it should be like: [0] = "wuggah" [1] = "herp" [2] = "derp" [3] = "blah" [4] = "what" or appending one and deleting first. And I don't want to end up manually moving them one after another all of the entries to the next id.

  • How to block subreddits with BIND9?

    - by user1391189
    Please help me block NSFW subreddits like this one (http://www.reddit.com/r/NSFW/) I would like to keep access to SFW subreddits, but block certain subreddits that are distracting or NSFW. I know how to filter domains. (see files below) But how do I apply the filter only to certain subreddits? So far I have set up the following files: blocklist.conf zone "adimages.go.com" { type master; file "dummy-block"; }; zone "admonitor.net" { type master; file "dummy-block"; }; zone "ads.specificpop.com" { type master; file "dummy-block"; }; ... named.conf options { allow-query { 127.0.0.1; }; allow-recursion { 127.0.0.1; }; directory "c:\bind\etc"; notify no; }; zone "."

  • Why is my cron daemon is being killed every few minutes? OpenVZ?

    - by user113215
    As of about a week ago, my cron daemon refuses to stay running. I'm using Debian 6. Running something like pgrep cron shows that the daemon isn't running. I start the service with service cron start or /etc/init.d/cron start and it launches, but it disappears from the running process list after a few minutes (varying anywhere between 1 - 30 minutes before the process is killed again). Using strace -f service cron start, I can see that the process is being killed for some reason: nanosleep({56, 0}, 0x7fffa7184c80) = 0 stat("crontabs", {st_mode=S_IFDIR|S_ISVTX|0730, st_size=4096, ...}) = 0 stat("/etc/crontab", {st_mode=S_IFREG|0644, st_size=1100, ...}) = 0 stat("/etc/cron.d", {st_mode=S_IFDIR|0755, st_size=4096, ...}) = 0 stat("/etc/cron.d/php5", {st_mode=S_IFREG|0644, st_size=475, ...}) = 0 stat("/etc/cron.d/anacron", {st_mode=S_IFREG|0644, st_size=244, ...}) = 0 rt_sigprocmask(SIG_BLOCK, [CHLD], [], 8) = 0 rt_sigaction(SIGCHLD, NULL, {0x4036f0, [CHLD], SA_RESTORER|SA_RESTART, 0x2b0e8465f230}, 8) = 0 rt_sigprocmask(SIG_SETMASK, [], NULL, 8) = 0 nanosleep({60, 0}, <unfinished ...> +++ killed by SIGKILL +++ There's nothing relevant in /var/log/syslog, /var/log/messages, /var/log/auth.log, or /var/log/kern.log to explain why the the process is dying. The system has about 500 MB of free memory, and cat /proc/loadavg returns 0.10 0.21 0.45 so resources shouldn't be the issue. I also tried removing and reinstalling the cron package using apt-get. What else should I check? How do I find out what's killing my crond? Edit: I'm on a virtual machine under OpenVZ (and as such, I have no swap). With cron running, free -m reports: total used free shared buffers cached Mem: 1024 465 558 0 0 0 -/+ buffers/cache: 465 558 Swap: 0 0 0 My OpenVZ User Beancounters via cat /proc/user_beancounters: Version: 2.5 uid resource held maxheld barrier limit failcnt 172087: kmemsize 8275718 25561636 51200000 51200000 0 lockedpages 0 968 2048 2048 0 privvmpages 113442 266465 262200 262200 3740757 shmpages 788 4004 128000 128000 0 dummy 0 0 0 0 0 numproc 39 98 600 600 0 physpages 50521 208434 0 9223372036854775807 0 vmguarpages 0 0 512000 512000 0 oomguarpages 50521 208447 512000 512000 0 numtcpsock 7 323 4096 4096 0 numflock 7 64 2048 2048 0 numpty 1 4 32 32 0 numsiginfo 0 23 1024 1024 0 tcpsndbuf 137984 17878480 20480000 20480000 0 tcprcvbuf 114688 6983504 20480000 20480000 0 othersockbuf 162960 1074440 20480000 20480000 0 dgramrcvbuf 0 24208 10240000 10240000 0 numothersock 101 353 2048 2048 0 dcachesize 459171 747444 10240000 10240000 0 numfile 1010 4221 50000 50000 0 dummy 0 0 0 0 0 dummy 0 0 0 0 0 dummy 0 0 0 0 0 numiptent 39 424 2048 2048 0

  • WPF TreeView databinding to hide/show expand/collapse icon

    - by Julian Lettner
    I implemented a WPF load-on-demand treeview like described in this (very good) article. In the mentioned solution a dummy element is used to preserve the expand + icon / treeview item behavior. The dummy item is replaced with real data, when the user clicks on the expander. I want to refine the model by adding a property public bool HasChildren { get { ... } } to my backing TreeNodeViewModel. Question: How can I bind this property to hide/show the expand icon (in XAML)? I am not able to find a suitable trigger/setter combination. (INotifyPropertyChanged is properly implemented.) Thanks for your time. Update 1: I want to use my property public bool HasChildren instead of using the dummy element. Determining whether or not an item has children is somewhat costly, but still much cheaper than fetching the children.

  • Converting C# void* to byte[]

    - by Yurik
    In C#, I need to write T[] to a stream, ideally without any additional buffers. I have a dynamic code that converts T[] (where T is a no-objects struct) to a void* and fixes it in memory, and that works great. When the stream was a file, I could use native Windows API to pass the void * directly, but now I need to write to a generic Stream object that takes byte[]. Can anyone suggest a hack way to create a dummy array object which does not actually have any heap allocations, but rather points to an already existing (and fixed) heap location. This is the pseudo-code that I need: void Write(Stream stream, T[] buffer) { fixed( void* ptr = &buffer ) // done with dynamic code generation { int typeSize = sizeof(T); // done as well byte[] dummy = (byte[]) ptr; // <-- how do I create this fake array? stream.Write( dummy, 0, buffer.Length*typeSize ); } }

  • Get the file path of current application's config file

    - by dummy
    The reason I asked this question is that I wanted to create a helper class for Remoting instantiation, and wanted to pass the appropriate app.exe.config (or web.config) file path to the RemotingConfiguration.Configure method, depending on the caller. Is there a way I could get the name of the config file for both Win and Web apps without checking if the application is Web or WinForms?

  • pure-specifier on function-definition

    - by bebul
    While compiling on GCC I get the error: pure-specifier on function-definition, but not when I compile the same code using VS2005. class Dummy { //error: pure-specifier on function-definition, VS2005 compiles virtual void Process() = 0 {}; }; But when the definition of this pure virtual function is not inline, it works: class Dummy { virtual void Process() = 0; }; void Dummy::Process() {} //compiles on both GCC and VS2005 What does the error means? Why cannot I do it inline? Is it legal to evade the compile issue as shown in the second code sample?

  • Creating parameterized type object using annonymous class

    - by Andrei Fierbinteanu
    This might be a stupid question, but I just saw a question asking how to create a Type variable for a generic type. The consensus seemed to be that you should have a dummy method returning that type, and then use reflection to get it (in this case he wanted Map<String, String>). Something like this : public Map<String, String> dummy() { throw new Error(); } Type mapStringString = Class.forName("ThisClass").getMethod("dummy").getGenericReturnType(); My question is, not having used reflection that much, couldn't you just do something like: Type mapStringString = new ParameterizedType() { public Type getRawType() { return Map.class; } public Type getOwnerType() { return null; } public Type[] getActualTypeArguments() { return new Type[] { String.class, String.class }; } }; Would this work? If not, why not? And what are some of the dangers/problems if it does (besides being able to return some Type like Integer<String> which is obviously not possible.

  • Acer sound card

    - by Rob Brugh
    Hi I have an acer aspire on a recent upgrade somehow it loaded dummy output into upper memory so every time I boot up I have to manually load my sound card. using sudo /sbin/alsa reload then alsamixer and f6 to change to my proper sound card. How do I go about making that my default sound card loading on boot every time. sometimes the message comes up cannot find alsamixer, if that happens I have to run the following command sudo /sbin/alsa force-reload and then alsamixer. That works only on current session I would like to get that so it boots without coming up with dummy output. anyone out there know what the command is to make that load to boot section?

  • FTP Server upload and filesystem questions

    - by Alex
    I'm a photographer who mainly does event photography. A while ago I bought myself a Nikon WT-4 wireless transmitter, a small device which connects via USB to my Nikon D700 DSLR, and then establishes a WiFi connection to an existing WLAN. It can then upload any pictures I take via FTP to an FTP server somewhere in the network. On my laptop I then have a piece of software which will check a given folder on the disk regularly, this software is smart enough to look at the modified file timestamp, if this timestamp is less than 10 seconds ago, it will not attempt to import the folder and skip the file in this iteration of the import scan. The problem I've discovered seems to be inherent to the FTP protocol, as I have the same problem with Windows 7 built in IIS server, as I do with FileZilla FTP server. When the transmitter starts to upload a file, the FTP server will create a small 300-500 KB file with the correct filename on the disk, but then do nothing with the file until it has completely received the file via FTP. So it seems to create this small dummy file, and then buffer the remainder of the FTP upload until it's finished, and then dump the rest of the file into the dummy file making it the correct size. Problem is, these uploads take about 15-30 seconds depending on reception, but since the folder watch tool will already try to import any file older than 10 seconds, it will always try to import the small dummy files which obviously fails as they're not copmlete yet. Is there any way to 'disable' this behaviour? Ideally I would like my file only to show up once it's been completely uploaded. Or perhaps someone knows another FTP server application (it has to run on win7) which does not show this behaviour?

  • Creating a Type object corresponding to a generic type

    In Java, how can I construct a Type object for Map<String, String>? System.out.println(Map<String, String>.class); doesn't compile. One workaround I can think of is private Map<String, String> dummy() { throw new Error(); } Type mapStringString = Class.forName("ThisClass").getMethod("dummy", null).getGenericReturnType(); Is this the correct way?

  • Is There A Way To Apply CODE Formatting To A VB.Net TextBox?

    - by Jeff
    I'm playing with a simple string replacement editor for editing VB.Net functions outside of VB. Is there a way to apply VB.Net code formatting to a string? For example. The txtboxCodeEntry looks like this: If strVar="dummy" then 1 else 0 Endif I would like it to "autoformat" to: If strVar = "dummy" Then 1 Else 0 End If The formatting would match whatever formatting VB.Net does when you're editing code in the Visual Studio IDE. Thanks.

  • Have I pushed the limits of my current VPS or is there room for optimization?

    - by JRameau
    I am currently on a mediatemple DV server (basic) 512mb dedicated ram, this is a CentOS based VPS with Plesk and Virtuozzo. My experience with it from day 1 has been bad and I only could sooth my server issues with several caching "Band-aids," but my sites are not as small as they were a year ago either so the issues have worsen. I have 3 Drupal installs running on separate (plesk) domains, 1 of those drupal installs is a multisite, that consists of 5-6 sites 2 of those sites are bringing in actual traffic. Those caching "Band-aids" I mentioned are APC, which seemed to help alot initially, and Drupal's Boost, which is considered a poorman's Varnish, it makes all my pages static for anonymous users. Last 30day combined estimate on Google Ananlytics: 90k visitors 260k pageviews. Issue: alot of downtime, I am continually checking if my sites are up, and lately I have been finding it down more than 3 times daily. Restarting Apache will bring it back up, for some time. I have google search every error message and looked up ways to optimize my DV server, and I am beyond stump what is my next move. Is this server bad, have I hit a impossibly low restriction such as the 12mb kernel memory barrier (kmemsize), is it on my end, do I need to optimize some more? *I have provided as much information as I can below, any help or suggestions given will be appreciated Common Error messages I see in the log: [error] (12)Cannot allocate memory: fork: Unable to fork new process [error] make_obcallback: could not import mod_python.apache.\n Traceback (most recent call last): File "/usr/lib/python2.4/site-packages/mod_python/apache.py", line 21, in ? import traceback File "/usr/lib/python2.4/traceback.py", line 3, in ? import linecache ImportError: No module named linecache [error] python_handler: no interpreter callback found.

UPDATE: the whole thing is running in an openvz environment. i saw in users_beancounters that the numflock was a problem, so i increased it. but the problem still persists. maybe this helps: ulimit -a core file size (blocks, -c) 0 data seg size (kbytes, -d) unlimited scheduling priority (-e) 0 file size (blocks, -f) unlimited pending signals (-i) 515011 max locked memory (kbytes, -l) 64 max memory size (kbytes, -m) unlimited open files (-n) 1024 pipe size (512 bytes, -p) 8 POSIX message queues (bytes, -q) 819200 real-time priority (-r) 0 stack size (kbytes, -s) 10240 cpu time (seconds, -t) unlimited max user processes (-u) 515011 virtual memory (kbytes, -v) unlimited file locks (-x) unlimited cat /proc/user_beancounters Version: 2.5 uid resource held maxheld barrier limit failcnt 200: kmemsize 9309653 13357056 14372700 14790164 0 lockedpages 0 1008 2048 2048 0 privvmpages 675424 686528 1048576 1572864 0 shmpages 33 673 21504 21504 0 dummy 0 0 9223372036854775807 9223372036854775807 0 numproc 49 90 240 240 0 physpages 243761 246945 0 9223372036854775807 0 vmguarpages 0 0 1048576 1048576 0 oomguarpages 81672 83305 1048576 1048576 0 numtcpsock 6 8 360 360 0 numflock 175 188 512 512 8 numpty 1 9 16 16 0 numsiginfo 0 48 256 256 0 tcpsndbuf 104640 263912 1720320 2703360 0 tcprcvbuf 98304 131072 1720320 2703360 0 othersockbuf 32368 89304 1126080 2097152 0 dgramrcvbuf 0 2312 262144 262144 0 numothersock 19 28 360 360 0 dcachesize 2285052 3624426 3409920 3624960 0 numfile 616 870 9312 9312 0 dummy 0 0 9223372036854775807 9223372036854775807 0 dummy 0 0 9223372036854775807 9223372036854775807 0 dummy 0 0 9223372036854775807 9223372036854775807 0 numiptent 24 24 128 128 0

  • Printing a field with additional dots in haskell

    - by Frank Kluyt
    I'm writing a function called printField. This function takes an int and a string as arguments and then then prints a field like this "Derp..." with this: printField 7 "Derp". When the field consists of digits the output should be "...3456". The function I wrote looks like this: printField :: Int -> String -> String printField x y = if isDigit y then concat(replicate n ".") ++ y else y ++ concat(replicate n ".") where n = x - length y This obviously isn't working. The error I get from GHC is: Couldn't match type `[Char]' with `Char' Expected type: Char Actual type: String In the first argument of `isDigit', namely `y' In the expression: isDigit y In the expression: if isDigit y then concat (replicate n ".") ++ y else y ++ concat (replicate n ".") I can't get it to work :(. Can anyone help me out? Please keep in mind that I'm new to Haskell and functional programming in general.
