Welcome to the latest newsletter from 3SL that provides a mixture of news and technical information about us, and our requirements management and systems engineering tool “Cradle”. We would especially like to welcome everyone who has purchased Cradle in the past month and those who are currently evaluating Cradle for their projects and processes.
We hope that we, and Cradle, can deliver real and measurable benefits to all of the exciting development projects that we see every day through your regular contacts with our support team. If you have any problems, please do not hesitate to contact 3SL support here.
Showing Cell Titles in Views
Sometimes when displaying a nested view the cell titles take up a lot of space on the screen.
Within the View Details dialog you have the option to choose whether you want to display the cell titles:
As you can see you can choose to either:
Show the cell titles
Hide the cell titles
Show the cell titles only when the view is top-level
You can change the visibility of any of the component views that are being used to show linked items. In practice, most people either hide everything or show everything.
Following on from our recent Cradle-7.7 release, if you are not already a customer and would like more information about Cradle, you can download the software and a free evaluation licence. You can find this on our website, or you can request a webinar. If you are a customer and would like to upgrade, please contact 3SL for a Security Code and for any assistance you may require with the upgrade.
Upcoming Training Courses
We still have places available on our September Risk Management course. Learn how to identify, analyse, evaluate, treat and monitor the risks associated with activities or events within your business. This course is designed for project team leaders or managers who administer and manage risks.

The software package includes Cradle licences, a pre-defined schema and a comprehensive support package. This can be used in both unclassified (IL0) and OFFICIAL (certified IL3) deployments and covers the following elements:
Prices start from as little as £50.00 per user per month. Including email and phone support and full documentation included. Optional onsite support and training is available. This can be supplied on Windows® or Linux®.
A wide range of user customisation is available including:
Items’ (attributes, links and properties)
Display of chosen data and layout through queries, views, forms,
Processing data to give graphs, reports, documents, metrics, KPIs/dashboards, process
or search for Cradle. For an overview of Cradle, see our video here: We look forward to helping you achieve success on your future projects, or migrating existing ‘manual’ or disparate works into a fully encompassed solution.
We are pleased to announce the release of Cradle-7.7 which is available now for download from the downloadssection of the 3SL website. This is the latest version of Cradle.
3SL customers with active maintenance have been sent an e-mail notification, and details of which of their enhancement requests and bug reports are included in this new release. This is a significant Cradle release that increments the Cradle minor version number from 7.6 to 7.7. This means that the Security Codes for Cradle-7.6 or earlier will NOT work with this new Cradle-7.7 release. Therefore, if you want to upgrade to Cradle-7.7 then you MUST contact 3SL Support and request a Cradle-7.7 Security Code since your existing Cradle-7.6 Security Codes will NOT work with this new release.
New Cradle-7.7 Capabilities
This release contains a range of new capabilities, including:
Metrics added to graphs
New header option in views
Annular dial type added to Dashboards
Precision option added to Dashboards
Ability to test email setup from User Preferences
These new capabilities are shown below. For further information please refer to the Release Notes.
A snapshot is a read-only copy of all the information in a Cradle database at a specific point in time that can be viewed, in isolation, at any point in the future.
Snapshots can be created and selected from the Project tab in WorkBench:
Snapshots can also be created via the command line using c_prj.
When a user selects a snapshot, their access to information, cross references and definitions are determined by the contents of the user’s profile in the database, regardless of whether or not the user has a profile in the current snapshot and regardless of the contents of that user profile (if any) in the snapshot.
Cradle-7.7 includes a new type of graph which shows metric coverage or count of items with different categories set or unset. This is called a metric graph. An example is shown below:
Header Option in Views
A new Header option is now available in the dialog. This provides a way of showing grouped and coloured headings when output. Example output is shown below:
A new Baseline Summary List report has been included in this release. This outputs each baseline on it’s own row in a table.
The Baseline Summary report has been renamed to Baseline Summary Compact.
A Sort by filter has also been added to both the Baseline List report, Baseline Summary List report and the Baseline Summary Compact report. This provides the option to sort by the baseline name, when the baseline was opened or when the baseline was closed.
Annular Dial Type in Dashboards
A new dial type has been added to dashboards – Annular %.
This is an annular percentage of a single dashboard bandset within which the KPI resides:
Precision Option in Dashboards
A Precision option has also been added to dashboards. This sets the count of numbers displayed around a dashboard dial:
Test Email Setup
The setup of emails can now be tested from User Preferences by selecting the new Test Email button:
Pressing the Test Mail button produces the Mail Test dialog where you choose an email recipient and whether you want to send the test email in plain text.
Please note the only user names shown in the Recipient drop down are Cradle users in the project who have an email address defined in their User Profile.
You must contact 3SL for new Security Code(s) for Cradle-7.7. Cradle-7.7 will not accept Security Codes from Cradle-7.6 or any previous release.
Cradle clients (WorkBench, Web Access, Document Publisher for instance) and server (Cradle CDS) versions cannot be mixed. Therefore, you must upgrade all Cradle installations to 7.7.
Cradle-7.7 databases do not have the same format as Cradle-7.6 databases. Hence the Cradle-7.7 release includes a database converter for the transition from Cradle-7.6 to Cradle-7.7. Full details are available in the 7.7 release notes, and updated manuals in addition you can always contact email@example.com .
Single User Products
Please note that there are no maintenance services for single-user Cradle products. Therefore, if you have purchased any of the single-user Cradle-7.6 products:
then you will not be able to request a new Cradle-7.7 Security Code. If you want to update your single-user Cradle system to the new Cradle-7.7 release, then you must buy the new Cradle-7.7 release.
Help with Cradle-7.7
In conclusion, we’re pleased with the new capabilities in Cradle-7.7 most importantly we hope you will benefit by upgrading. If you are not already a customer and would like more information about Cradle, you can download the software and a free evaluation licence, find more on our website, or request a webinar.

With the release of 7.7 coming very soon, we thought we’d test Cradle on additional platforms.
So here’s Cradle 7.7 running on a Steamdeck, in Desktop mode.
As SteamOS is based on Arch Linux, our 64 bit Linux version can be installed.
Both the CDS and WorkBench are running on this very capable device. A keyboard and mouse may work better than the on screen keyboard.
If you install the service manager (systemd script) then the Cradle Database Server (CDS) will start on boot up of the Steamdeck, so you might not want to do that if its primarily used for Steam. However, once started the CDS will stay running in the background when you switch to Gaming Mode. If you have others connecting to your CDS then they can continue to work while you improve your hand-eye coordination in your favourite game.
Although Steamdeck is not an officially supported platform, you can see Cradle does indeed run on additional platforms
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.
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.
We 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.
The 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.
The tantalising power of quantum computing offers unbounded possibilities to solve some of the biggest problems in computing today. So far the need to keep the Quantum Bits (QBits / QuBits) stable has proved the barrier to quantum computers being widely deployed. Laboratory conditions with super low temperatures and large magnetic fields have allowed the theory to be proved, but limit the practical implementation.
Our current silicon computers rely on simple 0 and 1 storage of bits to represent the data. These ons and offs are electrically, or optically stored and they are either one or the other. QuBits however are neither a 0 or a 1 until they are actually read. They exist in a ‘probability cloud’ between the true or false. The interaction of all the QuBits changes the probability that the bit will yield a 0 or 1 answer when read. This allows a massive scaling of parallel computation considering multiple avenues of a problem simultaneously.
The possibility that standard silicon based binary computers could be made to operate in a quantum state has raised many exciting possibilities. Studies at the Loe D’a Buncum institute hypothesises that a stated proof; that Black is White, or True is False, can be ‘proved’ either way. This uncertainty, they are terming an Argú (derived from the Latin argumentum “a logical argument; evidence, ground, support, proof”). They expect this will be widely applied to Silicon Based Computing Platforms (SBCP).
To paraphrase their research observe the following:
It can be seen that the composition of mixed primary light colours Red, Green and Blue gives White light. However, the same composite calculation for pigment Cyan, Yellow and Magenta gives Black. The Argú in this case is stated as :
Three primary colours mixed = Black = White.
This provides a state that can not be seen as a definitive answer (because there is a missing element – are we talking light or pigment). The key to unlocking and providing the definitive answer is being termed the Clú. This is the missing piece of information that will allow the quantum measurement to be extracted.
Because the concept itself, the Argú is simple to represent in standard boolean logic on a silicon computer, there is no need for any special cooling or magnetic field to retain the uncertainty. The Clú can also be held as a standard concept. The rest of the problem continues to be expressed in multiple Argús but not ‘finalised’. At the point where every possible Argú has been raised for a particular problem, the Clú is combined using standard logic simplified with De Morgan’s laws resulting in the final result.
Both QuBit and SBCP computing offer the gateway to many possibilities, but it should also be remembered that those without a Clú should not attempt to Argú.
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!)
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.
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.
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:
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 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.
Using a digital signature brings several benefits to anyone who installs or uses Cradle.
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.
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:
instead of the warning yellow UAC dialog.
Executable File Properties
You can verify the digital signature in the Cradle installation files:
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.
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.
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!
