Cheap Z68 motherboard

For Sale – MacBook Pro 13″ 2015. i5 2.9, 8GB RAM, 500GB HD, 1 year’s JL warranty remaining

I’m testing the waters here ……

Somewhat to my surprise, I’m upgrading to a new MacBook so my “old” one will be available by the beginning of next week.

It was bought new by me from John Lewis in February 2016 so has 13 months of the JL warranty remaining. It’s in excellent condition – I take very good care of all my tech – and has been protected by a shell case since day one. If the buyer wishes, I’ll include the case at no extra cost.

Battery count is currently at 348 because my practice is to charge the MacBook, then use it on a tray on my lap until it needs recharging, etc etc. Nothing has been unduly strained by hard usage: mostly, I visit various forums online, browse a number of other sites, and check emails.

This will come with all original packaging and accessories, all in the same excellent condition as the MacBook itself. I’m not sure whether there’s an Apple brown outer box because the unit was collected from JL, but if there isn’t the MacBook will be securely packaged inside another outer box before being posted. Amazon to the rescue again :).

The asking price is inclusive of RMSD. Collection is also possible, should a local buyer want to save a few £££. I’ll get some pics up tomorrow but in the meantime, if you’ve got any questions just ask.

Price and currency: £825
Delivery: Delivery cost is included within my country
Payment method: BT
Location: Bournemouth
Advertised elsewhere?: Not advertised elsewhere
Prefer goods collected?: I have no preference

Scale up your deep learning with Batch AI preview

Imagine reducing your training time for an epoch from 30 minutes to 30 seconds, and testing many different hyper-parameter weights in parallel. Available now, in public preview, Batch AI is a new service that helps you train and test deep learning and other AI or machine learning models with the same scale and flexibility used by Microsoft’s data scientists. Managed clusters of GPUs enable you to design larger networks, run experiments in parallel and at scale to reduce iteration time and make development easier and more productive. Spin up a cluster when you need GPUs, then turn them off when you’re done and stop the bill.

Developing powerful AI involves combining large data sets for training with clusters of GPUs for experimenting with network design and optimization of hyper-parameters. Having access to this capability as a service helps data scientists and AI researchers get results faster and focus on building better models instead of managing infrastructure. This is where Batch AI comes in as part of the Microsoft AI platform.

“Deep learning researchers require increasing computing time to train complex neural networks with big data. Large computing clusters on Microsoft Azure is one of the solutions to resolve our researchers’ pain, and Azure Batch AI will be the key solution to connect on-premises and cloud environments. Preferred Networks is excited to integrate Chainer & ChainerMN with this service.” –Hiroshi Maruyama, Chief Strategy Officer, Preferred Networks, Inc

Secret-to-AI

Joseph Sirosh, Corporate Vice President of the Cloud AI Platform, spoke at the recent Microsoft Ignite conference about delivering Cloud AI for every developer with a comprehensive family of infrastructure for AI in Azure, services for AI, and tools to make AI development easier. Batch AI is part of this infrastructure, enabling easily distributed computing on Azure for parallel training, testing, and scoring. Scale-out to as many GPUs as you want.

There’s a great demo in Joseph’s Ignite talk (25 minutes in) that shows an end-to-end experience of data wrangling, training at scale, and using a trained AI model in Excel. The model was developed initially using a Data Science Virtual Machine in Azure, then scaled out to speed up experimentation, hyper-parameter tuning, and training. Using Batch AI, our data scientists were able to scale from 1 to 148 GPUs for the model, reducing training time per epoch from 30 minutes to 30 seconds. This made a huge difference in productivity when you need to run thousands of epochs. Our data scientists were able to experiment with the network design and hyper-parameter values and see results quickly. A version of the code behind this demo will available as a tutorial to use with Batch AI and Azure ML Machine Learning Services and Workbench.

What is Batch AI

Batch AI provides an API and services specialized for AI workflows. The key concepts are clusters and jobs.

Cluster describes the compute resources you want to use. Batch AI enables:

  • Provisioning clusters of GPUs or CPUs on demand

  • Installing software in a container or with a script

  • Automatic or manual scaling to manage costs

  • Access to low priority virtual machines for learning and experimentation

  • Mounting shared storage volumes for training and output data

A job is the code you want to run — a command line with parameters. Batch AI supports:

  • Using any deep learning framework or machine learning tools

  • Direct configuration of options for popular frameworks

  • Priority-based job queue for sharing a GPU quota or reserved instances

  • Restarting jobs if a virtual machine becomes unavailable

  • SDK, command line, portal and tools integration

Building systems of intelligence

Dr. Yogendra Narayan Pandey, Data Scientist at Halliburton Landmark, used Azure Batch AI and Azure Data Lake to develop predictive deep learning algorithms for static reservoir modeling to reduce the time and risk in oil field exploration compared to traditional simulation. He shared his work at the Landmark Innovation Forum & Expo 2017.

“With the huge amounts of storage and compute power of the Azure cloud, we are entering the age of predictive model-based discovery. Batch AI makes it straightforward for data scientists to use the tools they already know. Without Azure Batch AI and GPUs, it would have taken hours if not days for each model training job to complete.”

Batch AI includes recipes for popular AI frameworks that help you get started quickly without needing to learn the details of working with Azure virtual machines, storage, and networking. The recipes include cluster and job templates to use with the Azure CLI interface, as well as Jupyter Notebooks that demonstrate using the Python API.

End-to-end productivity

The Batch AI team is working to integrate with Microsoft AI tools including the Azure Machine Learning services and Workbench for data wrangling, experiment management, deployment of trained models, and Visual Studio Code Tools for AI.

E2E-AI

Partners around the world are also using Batch AI to help their customers scale-up their training to Azure and its powerful fleet of NVIDIA GPUs.

“We have long needed a service like Azure Batch AI. It is an appealing solution for deep learning engineers to speed up deep neural network training & hyper parameter search. I’m looking forward to creating end-to-end solutions by integrating our deep learning service CSLAYER and Azure Batch AI.”  –Ryo Shimizu, President & CEO of UEI Corporation

Getting started

We invite you to try Batch AI for training your models in parallel and at scale in Azure. We have sample recipes for popular AI frameworks to help you get started. We recommend starting with low priority virtual machines to minimize costs.

With Batch AI, you only pay for the compute and storage used for your training. There’s no additional charge for the cluster management and job scheduling. Using low priority virtual machines with Batch AI is the most cost-effective way to learn and develop until you are ready to leverage GPUs.

The team would like to hear any feedback or suggestions you have. We’re listening on Azure Feedback, Stack Overflow, MSDN, and by email.

Artificial intelligence in software testing has arrived

What if software testing could undergo a metamorphosis, becoming better, faster and less expensive all the while letting testers focus on what they excel at? That rosy future could happen, thanks to a sudden interest in artificial intelligence in software testing.

Enterprise solutions provider Infostretch just announced it will offer artificial intelligence in software testing through a brand new service called Predictive and Prescriptive QA. Infostretch isn’t the only option — San Francisco-based startup Appdiff is also bringing machine learning “bots” online as testers. And dinCloud recently announced “James,” a virtual robot QA.

With continuous delivery, continuous integration and DevOps as the hot topics in every software development conversation today, the pressure on testers has never been more intense. “The thing is your crew cannot keep up with the amount of testing that should happen,” Appdiff CEO Jason Arbon said. “That’s one reason for Appdiff. … People can’t keep up any more.”

What about machine learning?

The solution is artificial intelligence in software testing, or more specifically, an AI subset: machine learning. “Today there are tons and tons of test data and it’s very hard for a single person to get through it all,” said Avery Lyford, chief customer officer at Infostretch. “It’s tons of report management now. Where are the real issues and what are the real problems?” That is where artificial intelligence in software testing can come in and help sort through the noise, Lyford said.

Infostretch is offering the Predictive and Prescriptive QA product as a service. With a heavy focus on data analysis, Lyford said the artificial intelligence in software testing tool can help streamline the testing process by ensuring the right information is in the hands of the testers who can then make better decisions. The new service can also be used in conjunction with the company’s QMetry offering.  

AppDiff is taking a slightly different approach, Arbon said. “We’re going from the end user experience backwards,” he said. “AI bots can do tens of thousands of test cases versus 20 to 100 regression test cases. This plays into today’s DevOps plan to iterate quickly.” Using artificial intelligence in software testing, companies will always know if the UI isn’t working or the UX is struggling, he said.

But these aren’t just any bots. Arbon, who previously worked at Google and has a background in software testing, realized a fundamental truth about applications that make bots effective testers. “Almost every app is the same,” he explained. “It’s the same log-in screen, most search boxes look the same, the profile, the shopping carts, there are a lot of similarities.” With that understanding — and the idea that each bot could be trained as a specialist in a single area like just the search box — Arbon was able to create bots that were better than the average tester. “The little bots are specialists on each area of the app and while they’re not as smart as a human might be, they’re the best search testers on the planet.” Arbon, and his colleagues who come from Google and Microsoft, train their bots to test like they did. “It’s like we’ve created a “Google tester” in a box. This replicates what we would do with your app.”

And, amazingly, there may be a silver lining in this for testers, many of whom fear being automated — or AI’d — out of a job. “The folks we work with don’t get fired,” Arbon said. “They get to hand off work and focus on doing things they’re good at.” Or to put it another way, it’s eliminating the grunt work and allowing testers to do the human, creative things they’re better at, said Paul Merrill, principal software engineer in test and founder of Beaufort Fairmont Automated Testing Services, at the Agile2017 conference in Orlando. Lyford sees it as giving testers back that elusive element of time. “We want people to be able to do complicated edge cases, not the routine stuff. This is to augment testers, not replace them.”

Use PowerShell when working with Hyper-V checkpoints

images of Hyper-V VM. For example, you can take checkpoints of a VM, perform your application testing and revert the checkpoint to a known state if you need to retest. Although you can use Hyper-V Manager to perform checkpoint tasks, it’s easier to do the same tasks using PowerShell.

By default, Hyper-V checkpoints aren’t enabled on VMs. In order to execute the PowerShell commands below, you’ll be required to enable checkpoints on the VMs. You can use the Hyper-V Manager to enable checkpoints for a VM, but you can also execute the Set-VM PowerShell cmdlet. To enable checkpoints for a single VM, execute the Set-VM –Name SQLVM –CheckPointType Enable PowerShell command. Next, run Set-VM –Name SQLVM –CheckPointType ProductionOnly to configure the VM to use a production checkpoint — first introduced in Hyper-V 2016.

Once you have enabled checkpoints for a VM, you can execute the below PowerShell commands to take checkpoints or revert to a checkpoint of your choice.

Create a checkpoint

To create a checkpoint, use the CheckPoint-VM PowerShell cmdlet. Just executing CheckPoint-VM –Name SQLVM will create a checkpoint for an SQLVM. If you need to take another checkpoint, execute the same command. Note that when you take a checkpoint, Hyper-V creates a checkpoint entry with the date and time when the checkpoint was taken.

To list all of the Hyper-V checkpoints for a VM, use Get-VMSnapshot –VMName SQLVM.

Note that the Checkpoint-VM PowerShell cmdlet doesn’t support taking checkpoints for a VM running on a remote Hyper-V host. If you need to perform a checkpoint for a remote VM, interact with the remote VM using the Get-VM PowerShell cmdlet and then pipe the Checkpoint-VM cmdlet as shown in the command below:

Get-VM Remote_SQLVM –ComuterName RemoteHyper-VHost | Checkpoint-VM

By using the command above, you are performing a checkpoint for a VM that is running on RemoteHyper-VHost.

To restore or revert to a checkpoint for a VM, use the Restore-VMSnapshot PowerShell cmdlet. If you would like to restore an SQLVM to a previous checkpoint, execute the PowerShell commands below:

$ThisVM = “SQLVM”

$ThisVM | Get-VM | Get-VMSnapshot –Name “SnapshotName” | Restore-VMSnapshot –Confirm:$False

Note that you will be required to stop the VM before performing the checkpoint restore operation.
