For Sale – Microsoft Surface Pro 3, Intel corei5, 256gb SSD, 8Gb mem

Hi,
I have for sale a Microsoft Surface Pro 3 laptop with Intel core i5 processor, 256gb SSD and 8gb of memory, Surface Pen and charger.

The laptop is in excellent condition and fully working with the exception of the docking port at the bottom of the tablet which is is not working however there are no cosmetic issues.

As a result I use a Bluetooth keyboard (which looks like a surface keyboard and is shown in the photos, US layout) instead of a Surface keyboard as that used the docking port for power.

All Bluetooth and usb keyboards and mice, peripherals etc will work as normal, it only affects the official surface keyboard and dock.

The laptop also comes with a UAG protector which in itself is worth around £40 and gives a bit more protection against drops.

EDIT: Wanted to add it also has the original box it came in.

JFrog taps partners, adds features to bolster DevOps platform

JFrog continues to bolster its core universal repository platform with new features and strategic partnerships to provide developers with a secure, integrated DevOps pipeline.

The Sunnyvale, Calif. company’s continued evolution includes partnerships with established companies to provide services around JFrog’s flagship Artifactory universal repository manager. This week, JFrog partnered with RunSafe Security of McLean, Va. to help secure code as it is created.

Under the partnership, RunSafe’s security software will plug into users’ Artifactory repositories to protect binaries and containers in development. RunSafe’s Alkemist tool adds protection to all compiled binaries as developers add them to Artifactory, said Joe Saunders, founder and CEO of RunSafe.

Alkemist inserts in CI/CD pipelines at build or deploy time. The security software hardens third-party, open-source components, compiled code that developers originate themselves, and it hardens containers as part of the process, he said.

“We immunize software without developer friction to enable continuous delivery of code or product,” Saunders said.

How RunSafe works with JFrog

Rather than scanning and testing the code, RunSafe inserts protections into the code without changing the functionality, slowing it down, or introducing any overhead.

“We eliminate a major set of vulnerabilities that are often attributed to both open source and general compiled code,” Saunders said. “That is all the memory based attacks, things like buffer overflow, etc.”

RunSafe launched a beta program for developers to try out the Alkemist plugin, as memory corruption-based attacks can be devastating and stopping them is no trivial exercise in most development environments.

“When a determined attacker understands the layout and memory allocations within an application, they can craft targeted exploits to devastating effect,” said Chris Gonsalves, senior vice president of research at The 2112 Group in Port Washington, N.Y. “And they can keep using those attacks as long as the underlying binaries remain the same. What RunSafe does is bring reduced-friction binary hardening to app development.”

RunSafe uses a “moving target approach” that changes the underlying binary in a way that keeps the app’s functionality intact while destroying the effectiveness of previous attacks, Gonsalves said.

“Just when a hacker thinks they know precise location of a buffer overflow vulnerability and how to exploit it, boom, RunSafe’s Alkemist plugin for JFrog users switches things up and effectively neutralizes the attack,” he said. “This is hand-to-hand combat with the bad guys at the binary level. That it can be done with negligible performance overhead and zero change in app functionality makes it an effective and important layer of defense in DevSecOps.”

RunSafe employs a process known as binary randomization to thwart intruders. This process eliminates the footing that exploits need to find and identify vulnerabilities in code. Randomization is typically a runtime protection, but RunSafe has added it into the development process.

“What you see now, especially when you have to move faster, is a full integration with your security pipelines,” said Shlomi Ben Haim, CEO of JFrog. The goal is to be able to avoid or to quickly resolve any kind of bugs or violations of vulnerability or license compliance issues, he said. “We want to provide continuous deployment all the way to the edge, fully automated, with no script.”

JFrog-Tidelift deal assures open source integrity

Regarding open source license compliance, JFrog recently partnered with Boston-based Tidelift. The companies introduced an integration between the Tidelift Subscription, a managed open source subscription, and JFrog Artifactory.

Tidelift checks that open-source software it supports is clean and secure with no licensing issues. The combination of the Tidelift Subscription and JFrog Artifactory gives development teams assurance  that the open source components they are using in their applications ‘just work’ and are properly managed, said Matt Rollender, Tidelift’s vice president of global partners, strategic alliances and business development, in a blog post.

“Customers save time by being able to offload the complexity of managing open source components themselves, which means they can develop applications faster, spend less time managing security issues and build fails, while improving software integrity,” said Donald Fischer, CEO of Tidelift.

As more enterprises include large amounts of open-source code to their repertoires, companies like Tidelift allow developers to use open-source without having to think twice. While Tidelift is somewhat unique in its approach, its competitors could include Open Collective, License Zero, GuardRails and Eficode.

“Tidelift is taking a very interesting approach to developing a way to sustainably manage the maintenance on open source software components and tools that are used at enterprise development,” said Al Gillen, an analyst at IDC. “The company is filling a niche that is not readily addressed by any other solutions in the market today.”

The Tidelift Subscription ensures that all open-source software packages in the subscription are issue-free and are backed and managed by Tidelift and the open source maintainers who created them.

“This means comprehensive security updates and coordinated responses to zero-day vulnerabilities, verified-accurate open source licenses, indemnification, and actively maintained open source components,” Rollender said.

JFrog tool updates

At its SwampUp 2020 virtual conference in June, JFrog introduced several new offerings and updates to existing products.

The company introduced CDN-based and peer-to-peer software package distribution mechanisms to help companies that have to deliver large volumes of artifacts to internal teams and external clients. The company also released new features for its JFrog Pipelines CI/CD offering, expanding the number of pre-built common functions, known as “Native Steps.”

In addition, JFrog introduced ChartCenter, a free community repository that provides immutable Helm Chart management for developers. Helm charts are collections of files that describe a related set of Kubernetes resources.

While JFrog has made some good strategic moves, a lot of them only strengthen the company’s core business as a repository, said Thomas Murphy, a Gartner analyst.

“They have a solid footprint and are very robust, but the question is, over the next three years as we see a move from a toolchain of discrete tools to integrated pipelines and value stream tooling, what do they do to be bigger and broader?” Murphy said. “I think of the growth in ability of GitLab and GitHub, and the expansion of Digital.ai and CloudBees in contrast.”

PowerShell 7 remoting expands management horizons

When PowerShell Core 6 was released in January 2018, a key feature was cross-platform PowerShell remoting that opened up this management tool to Linux administrators.

The March 2020 release of PowerShell 7 delivered many new and updated features. In addition to dropping the Core moniker and Microsoft adding the tool to long-term support, PowerShell 7 arrived with an easier remoting setup process that should encourage its use beyond the Windows OS.

Using PowerShell 7 remoting between Windows and Linux currently requires SSH transport on both sides. Linux only supports the SSH transport, but Windows supports the traditional WS-MAN remoting method and SSH as a newer option.

How to set up Windows SSH remoting for PowerShell 7

For this article, we will use Windows Server 2019 which has native SSH functionality. You can also use Windows 10 build 1809 which has built-in SSH. It is possible to use Windows Server 2016, but the features are not built in and require a bit more configuration.

To find out the installed features, run the following PowerShell command:

Get-WindowsCapability -Online | Where-Object Name -like 'OpenSSH*' | Format-Table -AutoSize
installed OpenSSH features
Use PowerShell to determine the installed OpenSSH features.

By default, the OpenSSH.Client~~~~0.0.1.0 feature is installed. To install the server component, run the following command using the Deployment Image Servicing and Management cmdlets to add the OpenSSH.Server~~~~0.0.1.0 Windows Feature:

Add-WindowsCapability -Online -Name 'OpenSSH.Server~~~~0.0.1.0'

Enable PowerShell 7 remoting

Additionally, you need to register the endpoint names for PowerShell 7 by running Enable-PSRemoting -SkipNetworkProfileCheck. This can cause issues if you are attempting to remote to a Windows system and use PowerShell 7 as the environment. Windows.PowerShell is the default configuration, but to specifically use PowerShell 7, you would need to call that endpoint while connecting.

Register the endpoint names
Register the endpoint names to use PowerShell 7 remoting.

This command registers the endpoint names to allow for remoting and are specific to the latest PowerShell version, in this case 7.0.1. We specify the -SkipNetworkProfileCheck parameter because any Public network will end the Enable-PSRemoting command early. As long as you are aware of the ramifications and proper control of this, then it is safe to run this command.

Configure the SSH server on Windows

After installation, set the SSH server to start automatically:

Start-Service -Name 'sshd'
Set-Service -Name 'sshd' -StartupType 'Automatic'

Next, we need to configure SSH before using it in PowerShell 7 remoting. Open the sshd_config with notepad or your editor of choice:

notepad $Env:ProgramDatasshsshd_config

Add the following configurations to the sshd_config file:


Subsystem powershell c:/progra~1/powershell/7/pwsh.exe -sshs -NoLogo -NoProfile
PasswordAuthentication yes
PubkeyAuthentication yes

Once saved and configured, run the following command:

Restart-Service -Name 'sshd'

This will restart the SSH server and load the changed configurations.

There is a bug in the OpenSSH server version included with Windows. It requires that 8.3 short names be used for any file paths, hence c:/progra~1. To verify that you are using the correct 8.3 short name, you can use the following command to retrieve this for the Program Files folder where PowerShell 7 is installed:

Get-CimInstance Win32_Directory -Filter 'Name="C:\Program Files"' | Select-Object EightDotThreeFileName

PowerShell 7 remoting setup on the Linux side

In this article, we will be using Ubuntu 18.04 and there are just a handful of configurations necessary to make PowerShell 7 remoting work with Linux. Follow these commands to install PowerShell 7 on Ubuntu.

wget -q https://packages.microsoft.com/config/ubuntu/18.04/packages-microsoft-prod.deb
sudo dpkg -i packages-microsoft-prod.deb
sudo apt-get update
sudo add-apt-repository universe
sudo apt-get install -y powershell

Both the SSH server and client should already be installed, and there are just a few changes necessary in /etc/ssh/sshd_config. For this tutorial, we will set PasswordAuthentication to yes with the following command:

PasswordAuthentication yes

You should avoid this practice in production. Typically, it is best to use public/private keys for authentication instead of password-only, but this can be useful for testing purposes.

Finally, powershell needs to be set as a subsystem for SSH with the following command:

Subsystem powershell /usr/bin/pwsh -sshs -NoLogo -NoProfile

After the configurations are set, restart the SSHD service:

sudo service sshd restart

Remoting to Linux from Windows

To connect to remote Linux machines, it is very simple using public/private keys. First, let’s set up the session for use in remoting.

$Session = New-PSSession -HostName '165.227.199.246' -KeyFilePath 'id_ed25519_key' -UserName 'root'
Enter-PSSession

In this case, we are going to draw the first five processes from the remote Linux machine. As you may be able to tell from the accounts-daemon process, we are looking at a Linux system.

Invoke-Command -Session $Session -ScriptBlock { Get-Process | Select-Object -First 5 | Format-Table -AutoSize }
Linux machine processes
Connect to the remote Linux machine using PowerShell 7 remoting from a Windows system to get the list of processes.

Remoting to Windows from Linux

Conversely, we can remote to Windows from Linux using a very similar method.

$Session = New-PSSession -HostName '40.69.152.22' -UserName 'lc-admin'

Similar to the process when remoting to Linux from Windows, we can pull back the first five processes. As you can tell with the conhost processes, we are viewing data from a Windows machine.

Invoke-Command -Session $Session -ScriptBlock { Get-Process | Select-Object -First 5 | Format-Table -AutoSize }
Windows machine processes
Using PowerShell 7 remoting to connect to a remote Windows machine from a Linux system.

More functionality will arrive in time

PowerShell 7 with SSH opens up a new world of remote system management using PowerShell between disparate systems. Although not all features are available using the SSH transport yet, such as Just Enough Administration or remote endpoint configuration, those features will no doubt come in time.

Bought just before Christmas last year so just over 6 months old, in perfect condition. Has always been plugged into power so battery life is still as new and has been connected to monitor with separate keyboard and mouse so the keyboard and trackpad on laptop have hardly been used.

I did quite a bit of research before buying and this had lot of good reviews for thermals whilst gaming, performance and screen are excellent.

Still has 6 months manufacturers warranty and I also have a 3 year extended warranty which I haven’t activated yet so buyer can register to claim.

Selling as I wasn’t using the laptop away from house as originally intended and have built a pc instead.

RRP at time of buying was £1200

Asking £850. Collection would be preferred but can sort delivery out if needed
