SpeedUpSolR – Review

Solar Power Productivity

We were interested to be provided with a SpeedUpSolRTM unit. We thought we’d test the claims and share them with you.  The device works by “capturing ambient light waves and amplifying productivity software enhancements” We suspect a little has been lost in translation, however the blurb goes on to explain that generally workers want to complete their work more quickly in the daylight saving summer months (in our case anything after GMT turns to BST), in order to make the best of the rest of the day. By capturing the increased sunlight during these hours it can help speed up a your work by using their proprietary algorithm to assist and second guess the text or keys you are about to press. Once finished employees will have completed their schedule ahead of time and will be able to leave earlier benefiting their well-being.

The Unit

SpeedUpSolR device

Comprising a “bubble matrix silicon cell panel” which uses lenses based on omnidirectional fly eyes, maximum sunlight is captured in unit around 150mm long. The interface is s standard USB connector. The drivers download automatically, as it supports plug and play.

Testing

SpeedUpSolR video in useWe connected the SpeedUpSolRTM to a standard desktop and installed a copy of Cradle. We then closed the blinds on the window to simulate a darker time of day. The unit is balanced atop the monitor facing the window, to achieve maximum exposure. The staff member was then asked to simulate entering data for the requirement they were working on. You’ll see their usual speed of typing. We then opened the blinds to allow maximum light onto the SpeedUpSolRTM. This allowed the software to start its word guessing and action assisting operations. We think you’ll concur, there is a marked increase in speed.

Software

SpeedUpSolR softwareThe software bundled with the SpeedUpSolRTM includes an average light level monitor with a rolling 7 day count. It suggests that this can be used to co-inside with maximum productivity bursts for employees. It is also noted that by monitoring the peaks, in winter months people who suffer from Seasonal Affective Disorder (SAD) may be able to time their coffee breaks outside to maximise benefit.

 

Is Cradle designed in Cradle?

Yes! Why would you have a dog and bark yourself?

It would be a bit silly to have a requirements management tool and not use it to manage your requirements, wouldn’t it?  Cradle’s continued development is controlled within Cradle. Changes, testing and feature management are all controlled in a Cradle database. This allows us to track each change from the initial proposal or enhancement request through development and testing through to final documentation and release.

Ongoing Feature Development

This is the basic case of ‘Cradle designed in Cradle’. You can see from this sneaky peek at our 7.3 release a number of features you’ll benefit from in the coming months.

Obviously we have removed customer references, but this simple view shows the ‘Change‘ items that follow a lifecycle through Cradle. The Change has a set of Test Cases written to cover different aspects  from usability through to access permissions and of course that it matches the original design requirement.

During development and testing it is useful to get a quick overview. The hierarchy diagram above shows a simple view tracing from the feature through the Test Case to the Test Result. (GC: Luckily they all show ‘pass’ which is a relief as it is a feature I coded!)

Larger features

Again it is a case of Cradle designed in Cradle. For example Cradle 7.1’s SysML functionality, a separate project was used, as there were more collaborators, and the design team was spread both sides of the Atlantic. The view below shows multiple item types linked together, the «relationships», linked to the symbols, reported for the ‘act’ diagram type.

Digital Certificates in Cradle System Engineering Tool

Starting with the Cradle-7.2 release, we have included digital certificates in the executables in the Cradle system engineering tool distribution for Windows, including the Cradle installer itself.

Digital Certificates

Like a passport or a driver’s licence, digital certificates are issued by a Certificate Authority (CA) to provide proof of identity, in this case for verifying the identity of online entities. However, instead of containing a photograph and the signature of the certificate’s owner, a digital certificate binds the owner’s public key to the owner’s private key.

3SL (our full company name is Structured Software Systems Limited) has obtained a digital certificate from the CA Symantec that we can use to identify any file as being something that we have produced.

Cradle Systems Engineering Tool

3SL’s system engineering tool Cradle contains many executables and other files. These files are supplied as a single distribution file, such as:

Cradle72_Setup.exe

It is helpful to us, and to anyone who receives the Cradle software distribution or who looks at any executable that is claimed to be part of the Cradle system engineering tool, to know that:

  • The distribution
  • The files inside the distribution

have come from 3SL and have not been changed in any way after they were created by 3SL.

So, starting with Cradle-7.2, 3SL has digitally signed:

  • The Cradle software distribution
  • The executables inside the distribution

with our digital certificate.

Benefits

Using a digital signature brings several benefits to anyone who installs or uses Cradle.

Anti-Virus Products

Occasionally, some AV products have incorrectly claimed that a file in Cradle contains a virus. These incorrect reports are called false positives.

Now that Cradle executables are digitally signed, we expect that your AV product will report fewer false positives.

Installation

Since the Cradle installer is digitally signed, Windows will display the friendly blue User Account Control (UAC) dialog at the start of the Cradle installation:

cradle system engineering tool digital signatures
Windows Detects 3SL in Cradle System Engineering Tool Installer

instead of the warning yellow UAC dialog.

Executable File Properties

You can verify the digital signature in the Cradle installation files:

View Digital Certificates in Cradle Executables

If the file does not contain a digital certificate, then you know that the file has been tampered with since 3SL created it, or it was not created by 3SL at all.

Information Assurance

The use of digital certificates is part of 3SL’s commitment to ensuring that Cradle contributes to the information assurance practices in your organisation. You can find more details about other information assurance aspects of Cradle in our white paper here.

Summary

We hope that 3SL’s use of digital certificates in the distribution of, and executable files within, the Cradle system engineering tool will be helpful when you next install Cradle and when your AV products next scan a Cradle installation!
