Answer : This can be configured both by command-line ( nltk.download(..., download_dir=) or by GUI. Bizarrely nltk seems to totally ignore its own environment variable NLTK_DATA and default its download directories to a standard set of five paths, regardless whether NLTK_DATA is defined and where it points, and regardless whether nltk's five default dirs even exist on the machine or architecture(!). Some of that is documented in Installing NLTK Data, although it's incomplete and kinda buried; reproduced below with much clearer formatting: Command line installation The downloader will search for an existing nltk_data directory to install NLTK data. If one does not exist it will attempt to create one in a central location (when using an administrator account) or otherwise in the user’s filespace. If necessary, run the download command from an administrator account, or using sudo. The recommended system location is: C:\nltk_data (Windows) ;

Answer : You could do this with a pseudo element with left and right margin to overcome the padding issue: @import "https://maxcdn.bootstrapcdn.com/bootstrap/3.3.6/css/bootstrap.min.css"; .row-bordered:after { content: ""; display: block; border-bottom: 1px solid #ccc; margin: 0 15px; } <div class="container"> <div class="row row-bordered"> <div class="col-xs-10"> Heading Text </div> <div class="col-xs-2 text-right"> <a href="#"><span class="glyphicon glyphicon-pencil"></span></a> <a href="#"><span class="glyphicon glyphicon-trash"></span></a> </div> </div> </div> The solution above longer works in Bootstrap 4 due to switching to Flexbox, but a few modifications fixes it: .row-bordered { position: relative; } .row-bordered:after

Note This module is part of ansible-base and included in all Ansible installations. In most cases, you can use the short module name systemd even without specifying the collections: keyword. Despite that, we recommend you use the FQCN for easy linking to the module documentation and to avoid conflicting with other collections that may have the same module name. New in version 2.2: of ansible.builtin Synopsis Requirements Parameters Notes Examples Return Values Synopsis Controls systemd services on remote hosts. Requirements The below requirements are needed on the host that executes this module. A system managed by systemd. Parameters Parameter Choices/Defaults Comments daemon_reexec boolean added in 2.8 of ansible.builtin Choices: no ← yes Run daemon_reexec command before doing any other operations, the systemd manager will serialize the manager state. aliases: daemon-reexec daemon_reload boolean Choices: no ← y

Answer : This turned out to be a very interesting question. There are lots of links out there on this topic but they are ambiguous in describing the difference/relationship between the two. Best description I've found of the hard drive configuration for a Windows OS is this one: http://www.ntfs.com/hard-disk-basics.htm. It appears that MBR and Partition Table are in the same sector on a drive. The MBR is "smaller" in that it is the very first thing on the drive, that then uses the partition table to continue the boot process to a specific OS. The two command options effectively fix different links in the boot chain: /fixmbr replaces the information and small executable that reads the partition table to find where the OS may be located. So this exists on any drive that has been formatted and effectively exists to read the next little bit on the hard drive that tells where the/an OS is supposed to be located. In essence, this is not necessarily a Windows-speci

Answer : You've fallen foul of lazy evaluation - the result of Select will create a new set of tasks each time you iterate over it. You can fix this just by calling ToList() : var tasks = _factory.CreateMessage(settings) .Select(msg => SendScans(msg)) .ToList(); That way the set of tasks that you're awaiting will be the same set of tasks checked with your foreach loop. Instead of iterating over all tasks, you can get the Exceptions (if any) from the Task.WhenAll -Task: var taskResult = Task.WhenAll(tasks); try { await taskResult; } catch (Exception e) { if (taskResult.IsCanceled) { // Cancellation is most likely due to a shared cancellation token. Handle as needed, possibly check if ((TaskCanceledException)e).CancellationToken == token etc. } else if (taskResult.IsFaulted) { // use taskResult.Exception which is an AggregateException - which you can iterate over (it's a tree
