For Sale – MacBook Air (3,1) 11″ late-2010

First refusal to neuty.

Details (pretty much in screenshot):
– Core2Duo 1.6GHz
– 4GB RAM
– 128GB SSD
– nVidia GeForce 320M
– 45W power adaptor
– supports macOS High Sierra

Physical condition is pretty good for its age – no ugly scratch or dent though I recommend a inspection as a couple of nicks are difficult to photograph. Trackpad, ports, wireless are in full working condition (I treat my stuff well…).

It’s still a useable machine for its age but the fans will kick in for over-aggressive websites with multiple videos running (such as the online tabloids). This is not a problem for me as I usually use this MacBook Air to remote-login into other machines and browse the internet, reading emails, etc.

You will notice that this is a CEX purchase (invoice dated 24 Feb 2018) and I am not sure if the remaining warranty is transferrable. This is already a loss to me – so cheeky offers will be ignored.

Please note face-to-face exchange is preferred and delivery will be at buyer’s risk & discretion.

The nine roles you need on your data science research team

It’s easy to focus too much on building a data science research team loaded with Ph.D.s to do machine learning at the expense of developing other data science skills needed to compete in today’s data-driven, digital economy. While high-end, specialty data science skills for machine learning are important, they can also get in the way of a more pragmatic and useful adoption of data science. That’s the view of Cassie Kozyrkov, chief decision scientist at Google and a proponent of the democratization of data-based organizational decision-making.

To start, CIOs need to expand their thinking about the types of roles involved in implementing data science programs, Kozyrkov said at the recent Rev Data Science Leaders Summit in San Francisco.

For example, it’s important to think about data science research as a specialty role developed to provide intelligence for important business decisions. “If an answer involves one or more important decisions, then you need to bring in the data scientists,” said Kozyrkov, who designed Google’s analytics program and trained more than 15,000 Google employees in statistics, decision-making and machine learning.

But other tasks related to data analytics, like making informational charts, testing out various algorithms and making better decisions, are best handled by other data science team members with entirely different skill sets.

Data science roles: The nine must-haves

There are a variety of data science research roles for an organization to consider and certain characteristics best suited for each. Most enterprises already have correctly filled several of these data science positions, but most will also have people with the wrong skills or motivations in certain data science roles. This mismatch can slow things down or demotivate others throughout the enterprise, so it’s important for CIOs to carefully consider who staffs these roles to get the most from their data science research.

Here is Kozyrkov’s rundown of the essential data science roles and the part each plays in helping organizations make more intelligent business decisions.

Data engineers are people who have the skills and ability to get data required for analysis at scale.

Basic analysts could be anyone in the organization with a willingness to explore data and plot relationships using various tools. Kozyrkov suggested it may be hard for data scientists to cede some responsibility for basic analysis to others. But, in the long run, the value of data scientists will grow, as more people throughout the company are already doing basic analytics.

Expert analysts, on the other hand, should be able to search through data sets quickly. You don’t want to put a software engineer or very methodical person in this role, because they are too slow.

“The expert software engineer will do something beautiful, but won’t look at much of your data sets,” Kozyrkov said. You want someone who is sloppy and will run around your data. Caution is warranted in buffering expert analysts from software developers inclined to complain about sloppy — yet quickly produced — code.

Statisticians are the spoilsports who will explain how your latest theory does not hold up for 20 different reasons. These people can kill motivation and excitement. But they are also important for coming to conclusions safely for important decisions.

A machine learning engineer is not a researcher who builds algorithms. Instead, these AI-focused computer programmers excel at moving a lot of data sets through a variety of software packages to decide if the output looks promising. The best person for this job is not a perfectionist who would slow things down by looking for the best algorithm.

A good machine learning engineer, in Kozyrkov’s view, is someone who doesn’t know what they are doing and will try out everything quickly. “The perfectionist needs to have the perfection encouraged out of them,” she said.

Too many businesses are trying to staff the team with a bunch of Ph.D. researchers. These folks want to do research, not solve a business problem.

A data scientist is an expert who is well-trained in statistics and also good at machine learning. They tend to be expensive, so Kozyrkov recommended using them strategically.

A data science manager is a data scientist who wakes up one day and decides he or she wants to do something different to benefit the bottom line. These folks can connect the decision-making side of business with the data science of big data. “If you find one of these, grab them and never let them go,” Kozyrkov said.

A qualitative expert is a social scientist who can assess decision-making. This person is good at helping decision-makers set up a problem in a way that can be solved with data science. They tend to have better business management training than some of the other roles.

A data science researcher has the skills to craft customized data science and machine learning algorithms. Data science researchers should not be an early hire. “Too many businesses are trying to staff the team with a bunch of Ph.D. researchers. These folks want to do research, not solve a business problem,” Kozyrkov said. “This is a hire you only need in a few cases.”

Prioritize data science research projects

For CIOs looking to build their data science research team, develop a strategy for prioritizing and assigning data science projects. (See the aforementioned advice on hiring data science researchers.)

Decisions about what to prioritize should involve front-line business managers, who can decide what data science projects are worth pursuing.

In the long run, some of the most valuable skills lie in learning how to bridge the gap between business decision-makers and other roles. Doing this in a pragmatic way requires training in statistics, neuroscience, psychology, economic management, social sciences and machine learning, Kozyrkov said.

I know I had the boxes for the mouse and trackpad until very recently, I’m pretty sure I put them in the garage but I’d need to check.

Manage all your Hyper-V snapshots with PowerShell


It’s much easier to manage Hyper-V snapshots using PowerShell than a GUI because PowerShell offers the greater…

/**

*/
$(“#inlineregform”).find( “ul” ).removeClass(“default-list”);

/**
* Replace “errorMessageInput” class with “sign-up-error-msg” class
*/
function renameErrorMsgClass() {
$(“.errorMessageInput”).each(function() {
if ($(this).hasClass(“hidden”)) {
$(this).removeClass(“errorMessageInput hidden”).addClass(“sign-up-error-msg hidden”);
} else {
$(this).removeClass(“errorMessageInput”).addClass(“sign-up-error-msg”);
}
});
}

/**

function validateThis(v, form) {
var validateReturn = urValidation.validate(v, form);
renameErrorMsgClass();
return validateReturn;
}

window.open(this.href, “Consent”, “width=500,height=600,scrollbars=1”);
e.preventDefault();
});

flexibility. Once you’re familiar with the basic commands, you’ll be equipped to oversee and change the state of the VMs in your virtual environment.

PowerShell not only reduces the time it takes to perform a task using a GUI tool, but it also reduces the time it takes to perform repeated tasks. For example, if you want to see the memory configured on all Hyper-V VMs, a quick PowerShell command or script is easier to execute than checking VMs one by one. Similarly, you can perform operations related to Hyper-V snapshots using PowerShell.

A snapshot — or checkpoint, depending on which version of Windows Server you have — is a point-in-time picture of a VM that you can use to restore that VM to the state it was in when the snapshot was taken. For example, if you face issues when updating Windows VMs and they don’t restart properly, you can restore VMs to the state they were in before you installed the updates.

Similarly, developers can use checkpoints to quickly perform application tests.

Before Windows Server 2012 R2, Microsoft didn’t support snapshots for production use. But starting with Windows Server 2012 R2, snapshots have been renamed checkpoints and are well-supported in a production environment.

PowerShell commands for Hyper-V snapshots and checkpoints

Microsoft offers a few PowerShell commands to work with Hyper-V checkpoints and snapshots, such as Checkpoint-VM, Get-VMSnapshot, Remove-VMSnapshot and Restore-VMSnapshot

If you want to retrieve all the Hyper-V snapshots associated with a particular VM, all you need to do is execute the Get-VMSnapshot -VMName PowerShell command. For example, the PowerShell command below lists all the snapshots associated with SQLVM:

Get-VMSnapshot -VMName SQLVM

There are two types of Hyper-V checkpoints available: standard and production checkpoints. If you just need all the production checkpoints for a VM, execute the PowerShell command below:

Get-VMSnapshot -VMName SQLVM -SnapshotType Production

To list only the standard checkpoints, execute the following PowerShell command:

Get-VMSnapshot -VMName SQLVM -SnapshotType Standard

When it comes to creating Hyper-V checkpoints for VMs, use the Checkpoint-VM PowerShell command. For example, to take a checkpoint for a particular VM, execute the command below:

Checkpoint-VM -Name TestVM -SnapshotName TestVMSnapshot1

The above command creates a checkpoint for TestVM on the local Hyper-V server, but you can use the following command to create a checkpoint for a VM located on a remote Hyper-V server:

Get-VM SQLVM -ComputerName HyperVServer | Checkpoint-VM

There are situations where you might want to create Hyper-V checkpoints of VMs in bulk. For example, before installing an update on production VMs or upgrading line-of-business applications in a VM, you might want to create checkpoints to ensure you can successfully restore VMs to ensure business continuity. But if you have several VMs, the checkpoint process might take a considerable amount of time.

You can design a small PowerShell script to take Hyper-V checkpoints for VMs specified in a text file, as shown in the PowerShell script below:

$ProdVMs = “C:TempProdVMs.TXT”
Foreach ($ThisVM in Get-Content $ProdVMs)
{   
$ChkName = $ThisVM+”_BeforeUpdates”
Checkpoint-VM -Name $ThisVM -SnapshotName $ChkName
}
Write-Host “Script finished creating Checkpoints for Virtual Machines.”

The above PowerShell script gets VM names from the C:TempProdVMs.TXT file one by one and then runs the Checkpoint-VM PowerShell command to create the checkpoints.

To remove Hyper-V snapshots from VMs, use the Remove-VMSnapshot PowerShell command. For example, to remove a snapshot called TestSnapshot from a VM, execute the following PowerShell command:

Get-VM SQLVM | Remove-VMSnapshot -Name TestSnapshot

To remove Hyper-V checkpoints from bulk VMs, use the same PowerShell script you used to create the checkpoints. Let’s assume all the VMs are working as expected after installing the updates and you would like to remove the checkpoints. Simply execute the PowerShell script below:

$ProdVMs = “C:TempProdVMs.TXT”
Foreach ($ThisVM in Get-Content $ProdVMs)
{   
$ChkName = $ThisVM+”_BeforeUpdates”
Get-VM $ThisVM | Remove-VMSnapshot $ChkName
}
Write-Host “Script finished removing Checkpoints for Virtual Machines.”

To restore Hyper-V snapshots for VMs, use the Restore-VMSnapshot PowerShell cmdlet. For example, to restore or apply a snapshot to a particular VM, use the following PowerShell command:

Restore-VMSnapshot -Name “TestSnapshot1” -VMName SQLVM -Confirm:$False

Let’s assume your production VMs aren’t starting up after installing the updates and you would like to restore the VMs to their previous states. Use the PowerShell script below and perform the restore operation:

$ProdVMs = “C:TempProdVMs.TXT”
Foreach ($ThisVM in Get-Content $ProdVMs)
{   
$ChkName = $ThisVM+”_BeforeUpdates”
Restore-VMSnapshot -Name $ChkName -VMName $ThisVM -Confirm:$False
}
Write-Host “Script finished Restoring Checkpoints for Virtual Machines.”

Note that, by default, when restoring a checkpoint for a VM, the command asks for confirmation. To avoid the confirmation prompt, add the Confirm:$False parameter to the command, as shown above.
