i created advanced function mac address vm running on vmware esxi. function get-macfromvm { [cmdletbinding(supportsshouldprocess=$true)] param( # name of vm of want obtain mac address. [parameter(mandatory=$true, valuefrompipeline=$true, valuefrompipelinebypropertyname=$true)] [string[]] $name ) begin {} process { foreach ($item in $name) { if ($pscmdlet.shouldprocess($item, "getting mac address")) { get-vm $item -pipelinevariable vm | get-networkadapter | select-object @{n="name"; e={$vm.name}}, @{n="clientid"; e={$_.macaddress -replace ":","-"}} } } } end {} } so far works perfect. can use in of following ways , results back. it accepts either single or array of string via named parameter or pipeline input...

relatively r crashes when stm model converge. see image below 1 example after 30h+ estimation session. has happened on 2 different computers, different data sizes. have not been able identify specific patterns leading these crashes—as crashes not seem deterministic. the model estimation settings # full year <- year(df$date) # year data environment stmfit.full <- stm(out$documents, out$vocab, k = 0, prevalence =~ s(year) , max.em.its = 150, init.type = "spectral", seed = 300, verbose = t) any ideas how solve this? additional information: a) > #systeminfo > > library(stm) stm v1.2.2 (2017-03-28) loaded. see ?stm help. > > sessioninfo() r version 3.4.1 (2017-06-30) platform: x86_64-w64-mingw32/x64 (64-bit) running under: windows >= 8 x64 (build > 9200) > > matrix products: default > > locale: [1] lc_collate=swedish_sweden.1252 > lc_ctype=swedish_sweden.1252 lc_monetary=swedish_sweden.1252 > lc...

at moment, i'm programming compiler small subset of python in python. managed construct syntax tree got problems coding tree traversal (which essential generating code). i'll first go along showing data structures: class abstractsyntaxtree(object): def __init__(self, startsymbol): self.root = node(startsymbol, val=none) self.nodes = [self.root] def addnode(self, name, val, parentid): parent = self.nodes[parentid] self.nodes.append(node(name=name, val=val, parent=parent)) return len(self.nodes)-1 def getlastid(self): return len(self.nodes)-1 def __iter__(self): node in self.root: yield node this node definition: class node: def __init__(self, name, val, parent=none): self.name = name self.val = val self.parent = parent self.children = [] if parent: parent.children.append(self) def __iter__(self): yield self ...

so error message: php deprecated: mysql_connect(): mysql extension deprecated , removed in future: use mysqli or pdo instead this affected piece of code: class wdclient { var $dblink; // database link var $prefix; // table prefix var $script; // script running /** * construct new directory object. */ function wdclient() { error_reporting(e_all ^ e_notice); $this->prefix = wddbprefix; // connect database $this->dblink = mysql_connect(wddbhost, wddbuser, wddbpasswd); // select database mysql_select_db(wddbname, $this->dblink) or die('sorry, site unavailable!'); } where wddbprefix , wddbhost , wddbuser , wddbpasswd , wddbname defined in config file. i have tried using mysqli_connect instead of mysql_connect it's not working. note: never use mysql, use method! //mysqli information $db_host = ...

i'm trying put side-by-side numpy array displayed image , seaborn distplot of same array. i've came following function: def visualize(arr): f, (ax1, ax2) = plt.subplots(1, 2, gridspec_kw = {'width_ratios': [1, 3]}) ax1.imshow(arr) flat = arr.flatten() x = flat[~np.isnan(flat)] sns.distplot(x, ax=ax2) plt.show() which produces: as can see, image has smaller height plot. how can modify function in order have same height plot , imshow? i want following placement of image , plot: there many ways tackle this. of following give more or less same image a. reduce available space you may reduce available space such both plots constrained same vertical margins. can done by reducing figure height fig, (ax1, ax2) = plt.subplots(1, 2, figsize=(6,2.3), ...) using subplots_adjust limit margins fig.subplots_adjust(top=0.7, bottom=0.3) b. use insetposition you may use mpl_toolkits.axes_grid1.inset_locator.insetpositi...
