Make filing a habit: Find a time during the week to empty your To File basket and file those needed papers away. This task really shouldn't take long — 15 or 20 minutes should do it. Fine-tune later: At a later date, take a look at what's in your files. Usually, you find that a file is either underused or bulging.

Create a notebook

1. Click the Workspace button or the Home button in the sidebar. Do one of the following:

   • Next to any folder, click the on the right side of the text and select Create > Notebook.

   • In the Workspace or a user folder, click and select Create > Notebook.

2. In the Create Notebook dialog, enter a name and select the notebook's default language.

3. If there are running clusters, the Cluster drop-down displays. Select the cluster you want to attach the notebook to.

4. Trim enabler 3 5 – improve solid state drive performance. Click Create.

• Project or Client-Based File Organization System. A project or client-based structure is perhaps the simplest to stick to. Every project or client—how you split things up really depends on what sort of work you do—gets its own dedicated folder. Within each project or client folder, you keep all the relevant files and documents.
• In a nutshell, OneNote is a word processor that allows you quick access to all of your separate documents (pages) from one simple interface. You can then organize pages in Notebooks, Sections, or Sub sections. Enabling you to have all your notes at the tip of your fingers. Working faster & taking notes more effectively. Step 1: Get OneNote.

Open a notebook

In your workspace, click a . The notebook path displays when you hover over the notebook title.

Delete a notebook

See Folders and Workspace object operations for information about how to access the workspace menu and delete notebooks or other items in the Workspace. Acestream mac os.

Copy notebook path

To copy a notebook file path without opening the notebook, right-click the notebook name or click the to the right of the notebook name and select Copy File Path.

Rename a notebook

To change the title of an open notebook, click the title and edit inline or click File > Rename.

Control access to a notebook

If your Databricks account has the Premium plan (or, for customers who subscribed to Databricks before March 3, 2020, the Operational Security package), you can use Workspace access control to control who has access to a notebook.

Notebook external formats

Databricks supports several notebook external formats:

• Source file: A file containing only source code statements with the extension .scala, .py, .sql, or .r.
• HTML: A Databricks notebook with the extension .html.
• DBC archive: A Databricks archive.
• IPython notebook: A Jupyter notebook with the extension .ipynb.
• RMarkdown: An R Markdown document with the extension .Rmd.

In this section:

You can import an external notebook from a URL or a file.

1. Click the Workspace button or the Home button in the sidebar. Do one of the following:

   • Next to any folder, click the on the right side of the text and select Import.

   • In the Workspace or a user folder, click and select Import.

2. Specify the URL or browse to a file containing a supported external format.

3. Click Import.

In the notebook toolbar, select File > Export and a format.

Note

When you export a notebook as HTML, IPython notebook, or archive (DBC), and you have not cleared the results, the results of running the notebook are included.

If you're using Community Edition, you can publish a notebook so that you can share a URL path to the notebook. Subsequent publish actions update the notebook at that URL.

Notebooks and clusters

Before you can do any work in a notebook, you must first attach the notebook to a cluster. This section describes how to attach and detach notebooks to and from clusters and what happens behind the scenes when you perform these actions.

In this section:

When you attach a notebook to a cluster, Databricks creates an execution context. An execution context contains the state for a REPL environment for each supported programming language: Python, R, Scala, and SQL. When you run a cell in a notebook, the command is dispatched to the appropriate language REPL environment and run.

You can also use the REST 1.2 API to create an execution context and send a command to run in the execution context. Similarly, the command is dispatched to the language REPL environment and run.

A cluster has a maximum number of execution contexts (145). Once the number of execution contexts has reached this threshold, you cannot attach a notebook to the cluster or create a new execution context.

Idle execution contexts

An execution context is considered idle when the last completed execution occurred past a set idle threshold. Last completed execution is the last time the notebook completed execution of commands. The idle threshold is the amount of time that must pass between the last completed execution and any attempt to automatically detach the notebook. The default idle threshold is 24 hours.

When a cluster has reached the maximum context limit, Databricks removes (evicts) idle execution contexts (starting with the least recently used) as needed. Even when a context is removed, the notebook using the context is still attached to the cluster and appears in the cluster's notebook list. Streaming notebooks are considered actively running, and their context is never evicted until their execution has been stopped. If an idle context is evicted, the UI displays a message indicating that the notebook using the context was detached due to being idle.

If you attempt to attach a notebook to cluster that has maximum number of execution contexts and there are no idle contexts (or if auto-eviction is disabled), the UI displays a message saying that the current maximum execution contexts threshold has been reached and the notebook will remain in the detached state.

If you fork a process, an idle execution context is still considered idle once execution of the request that forked the process returns. Forking separate processes is not recommended with Spark.

Configure context auto-eviction

You can configure context auto-eviction by setting the Spark propertyspark.databricks.chauffeur.enableIdleContextTracking.

• In Databricks 5.0 and above, auto-eviction is enabled by default. You disable auto-eviction for a cluster by setting spark.databricks.chauffeur.enableIdleContextTrackingfalse.
• In Databricks 4.3, auto-eviction is disabled by default. You enable auto-eviction for a cluster by setting spark.databricks.chauffeur.enableIdleContextTrackingtrue.

To attach a notebook to a cluster:

1. In the notebook toolbar, click Detached .
2. From the drop-down, select a cluster.

Important

An attached notebook has the following Apache Spark variables defined.

Do not create a SparkSession, SparkContext, or SQLContext. Doing so will lead to inconsistent behavior.

Determine Spark and Databricks Runtime version

To determine the Spark version of the cluster your notebook is attached to, run:

To determine the Databricks Runtime version of the cluster your notebook is attached to, run:

Note

Both this sparkVersion tag and the spark_version property required by the endpoints in the Clusters API and Jobs API refer to the Databricks Runtime version, not the Spark version.

1. In the notebook toolbar, click Attached .

2. Select Detach.

Notebooks Create Documents Organize Files Manage Tasks 1 3 11

You can also detach notebooks from a cluster using the Notebooks tab on the cluster details page.

When you detach a notebook from a cluster, the execution context is removed and all computed variable values are cleared from the notebook.

Tip

Joan of arc game. Databricks recommends that you detach unused notebooks from a cluster. This frees up memory space on the driver.

The Notebooks tab on the cluster details page displays all of the notebooks that are attached to a cluster. The tab also displays the status of each attached notebook, along with the last time a command was run from the notebook.

Schedule a notebook

To schedule a notebook job to run periodically:

1. In the notebook toolbar, click the button at the top right.
2. Click + New.
3. Choose the schedule.
4. Click OK.

Distribute notebooks

To allow you to easily distribute Databricks notebooks, Databricks supports the Databricks archive, which is a package that can contain a folder of notebooks or a single notebook. A Databricks archive is a JAR file with extra metadata and has the extension .dbc. The notebooks contained in the archive are in a Databricks internal format.

Import an archive

1. Click or to the right of a folder or notebook and select Import.
2. Choose File or URL.
3. Go to or drop a Databricks archive in the dropzone.
4. Click Import. The archive is imported into Databricks. If the archive contains a folder, Databricks recreates that folder.

Export an archive

Click or to the right of a folder or notebook and select Export > DBC Archive. Databricks downloads a file named <[folder|notebook]-name>.dbc.

If you're anything like us, you probably have dozens of notebooks filled with fragments of thoughts and ideas strewn all around over the house. Note taking, after all, is the tool of choice for the consummate organizer. https://tr-free.mystrikingly.com/blog/auto-clicker-2. But what if you could ditch all those tedious paper notebooks and store all your thoughts in a digital repository? What if you could search through your notes, share them seamlessly with others, and access them from anywhere in the world?

This is the promise of OneNote, the note taking application that comes with Microsoft Office. Originally released as part of Office 2003, OneNote has quickly become the most powerful software of its kind on the market. Efficient, effective, and packed full with features, OneNote can help you get more done faster, provided you use it correctly.

How to Use OneNote Like a Pro

1. Sync Notebooks Online

Saving notebooks to your local computer is basically using OneNote like a glorified Notepad. To take real advantage of OneNote's features, you must save and sync all your notebooks online. Syncing means that all your notebooks get updated across all your devices in real time. This means you can create a new note on one your home computer before heading out to work, and resume using it on your laptop at the office. Neat, right?

But how exactly do you sync online?

Starting with Office 2013, OneNote actually prompts you to log into SkyDrive – Microsoft's cloud storage solution – to sync notebooks automatically. Besides SkyDrive, you can save and sync notebooks using Office 365 Sharepoint. You can also use DropBox for syncing – just make sure to select the DropBox folder on your computer when creating a new notebook.

You can also change sync settings to manual or automatic under ‘Sync Options' in the Info panel under File menu (OneNote 2013). The default setting is automatic; we suggest you keep it as is.

Unsure about using OneNote? Need a helping hand with MS Office? This Microsoft Office 2010 training course will introduce you to all the best features in OneNote, Excel, Word, Access and PowerPoint.

2. Take Audio/Video Notes

Typing notes into OneNote can get awfully tedious very soon. Spice up your routine by taking audio and video notes instead. Click on Insert -> Record Audio/Record Video to start taking notes. This is a more visual, interactive way to keep track of things – a solid alternative for when you get sick of typing things out. Plus, you can usually speak faster than you can type (unless you are Jack Nicholson!), so you'll probably save some time as well.

But to take real advantage of these notes, you must first let OneNote index your audio/video recordings. This will enable you to search through your audio/video notes just like any normal written message – a powerful feature for finding information.

To do this, go to File -> Options -> Audio & Video and select ‘Enable searching audio and video recordings for words'.

3. Organize Your Notebooks Effectively

OneNote is meant to be used as a physical notebook replacement. The program is most effective when you organize your notebooks like you would in the real world, that is, with individual notebooks for each subject/topic, separate sections for each sub-topic, and separate page for each note or groups of similar notes.

Most beginners tend to be very conservative with notebook and section creation. Don't be; you don't stand to lose anything save a few megabytes of space for each new notebook. Create as many notes, pages, sections and notebooks as you like – it'll make organization that much easier.

The program is most effective when you organize your notebooks like you would in the real world, that is, with individual notebooks for each subject/topic, separate sections for each sub-topic, and separate page for each note or groups of similar notes.

Most beginners tend to be very conservative with notebook and section creation. Don't be; you don't stand to lose anything save a few megabytes of space for each new notebook. Create as many notes, pages, sections and notebooks as you like – it'll make organization that much easier.

For example, if you are a college student, you can make a new notebook for each class you take in a semester. You can then make separate sections for each broad topic, and add pages of notes for each day of the class. You can see an example structure below:

4. Use OneNote to Make To-Do Lists

Still using pocket legal pads and post-it notes to make your daily to-do lists? OneNote offers a much better solution. Make a to-do list in the program by pressing CTRL+1 anywhere in the main note screen. OneNote will automatically create a list item with a checkbox next to it. Type in your list item, press enter, type in another item, and so on.

To cross-off an item on the list, simply click on the checkbox, or bring your text cursor to the list item and press CTRL+1 again.

It really is that easy!

Increase your productivity and get more things done with this course on how to work for yourself.

5. Take Advantage of Page Templates

Not many people use it, but OneNote page templates can be incredibly useful when done right. This is especially true for college students as OneNote 2013 comes packed with dozens of thoughtful templates right out of the box.

To access these templates, go to Insert -> Page Templates, and choose a template from the panel that pops up on the right.

The ‘Lecture Notes and Study Questions' template, for instance, looks like this:

Balsamiq mockups 3 5 17 20. Using templates makes note taking even faster. You can also save your current page as a template by clicking the ‘Save current page as template' link in the template panel.

6. Use Tags

One of OneNote's most powerful, yet underutilized feature is tagging. Tags work like hashtags in Twitter; every note or item marked with a particular tag will show up in the search results when you search for that tag.

To use tags, click on any of the built-in tags under the ‘Tags' section in the home ribbon.

You can also make your own custom tags in this section.

Use tags to organize your data. For example, you could mark important document with the ‘Important' tag, questions with the ‘Question' tag, and so on. Use keyboard shortcuts to tag items faster.

Consider an example: we created two note items and marked them with the ‘Important' (star) tag:

Clicking the ‘Find Tag' button on the home ribbon will show us all the notes marked with this tag:

You can also change the search options to include the current section, the current notebook, or even all your existing notebooks in the ‘Find Tag' panel.

As you can see, this is a very handy feature for organizing your information. Combined with custom search, it can help you never lose anything again.
