(1)  In iBasis coverage document released 2022-04-07 what do the value pairs, in seconds, mean in the right hand most four columns?<br />
 +
(2)  Does iBasis support periodic-TAU (Tracking Area Update) extended timer encoding, or only the older periodic-TAU?  In which regions?<br />

(3)  Using eDRX as a power savings mode, is there any necessary negotiation between User Equipment and provider, to establish UE registration persistence?<br />

<b>At the tester:</b>
+
Hello Mr. Goovaerts,
  
−
Dev sessions on GWN Sensor tester:
+
My name is Ted Havelka.  I am a friend and fellow alum of Andrew Greenberg, and one of the many Portland Aerospace Society participants who played a role, if small, over the years.  I still keep in touch with Andrew.  I am also employed as a firmware engineer at a local, Clackamas Oregon company where we have recently posted a job opportunity that's ideally suited for recent graduates on an embedded systems and firmware track.  Andrew suggested that I reach out to you and pass along our job posting.  Here is the link:
  
−
To perform development work on the Gas Platform Sensor Tester, host alta-gwn-sensor.veris.com, a necessary first step is to open a terminal window like Xterm and do the following steps:
+
*  https://recruiting.ultipro.com/ROP1001ROPER/JobBoard/5635cac7-6c69-44a7-850c-cf35112ce343/OpportunityDetail?opportunityId=eea2677d-12ab-4420-8507-0bded05f2e0f
  
−
<pre>
+
My supervisor is spearheading the initial interviews and will make hiring decisions.  As the lead firmware developer on a small IIoT team I'll be involved in interviewing candidates who we call for a second more in depth interview.  I hope it is appropriate for me to reach out to you this way.  Let me know whether there will be any graduates this spring of 2022 with a focus on firmware and embedded level design.
−
  $ gd1
 
  
−
  $ sudo link-to-dev
+
Thank you,
  
−
  $ ls -l
+
- Ted

</pre>

The first command is a local "directory bookmarking" shortcut to change directories to the Sensor Tester's share directory.  The GWN Sensor Tester reads a couple of run-time config files from this directory.
 
  
−
The second command is a name of a local script, which redirects a Unix-style symbolic link to point from Production tester's version of the gas sensors ConfigTable.csv file to the present branch version of this file.  By present branch I mean the 2019 Q1, Q2 branch in which we're extending the code to support new refrigerant sensors AG05 and AG06, and the new dual-gas sensor AG04.
 
  
−
The third command above give a long format directory listing.  I use this to confirm that the symlink points to the branch ConfigTable.csv file as opposed to Production's version of the file in the share directory itself.
+
2022-05-25 WED
  
−
When finished with a development session at the test station, use the following commands to point the symlink back to Production ConfigTable.csv:

Ted's questions:
  
−
  $ ls -l
+
(1)  In your skills and work history you've done a ton of stuff, when do you sleep?
−
</pre>
 
  
−
If you have left the original terminal window open and at the working directory of the station's /usr/local/share/gas_platform or similar, there's no need to invoke the local bookmarker alias named `gd1`.
+
(2)  Why the (potentially more challenging) switch from molecular biology to electrical engineering?
  
 +
(3)  Can you describe the "skills development process" you mention leading at Atypical Technology and Advanced Projects (ATAP)?
 +
    ( Is ATAP part of or the more modern times Computer Action Team at PSU School of Engineering? )

<b>To Test AG04 Stub Function</b>
 
  
−
To test the AG04 calibration function, which is as of 2019-05-03 only a stub, you will need on hand the AG04 bar code to read at the station, and an AG04 sensor module with correct ID resistor.  If by chance the sample AG04 module(s) you can obtain have an incorrect ID resistance, see notes further in this step about how to edit ConfigTable.csv to temporarily reflect the found ID resistance in a given sensor module type.
+
(4) Given your wide range of technical skills what most caught your eye in our Firmware Developer job description?
  
−
To test the stub function on the production floor host alta-gwn-sensor.veris.com, open a terminal window and use the local shortcut `gd20` to go to the directory of the Unified Tester branch for 2019 new sensors:
 
  
−
  $ gd20
 
  
 +
-->
  
−
After this step, start the GUI by typing:
+
<!-- 2022-05-26 THU

  $ ./gas-platform-unified-tester
+
Questions for Mr. Bliss Brass
  
 +
( Quick overview . . . )
 +
Your program of engineering study was specifically Computer Engineering, CE rather than EE by formal designation?  What made you choose this path?
  
−
<i>Note:  the <TAB> key pressed during typing of a program name or filename will auto-complete the name, as soon as the typed part is unique among files in the current directory.</i>
 
  
−
Once the GUI main window appears, there will be some scrolling text output in the parent or controlling terminal window of the GUI.  This is normal, and it means also that the GUI is ready to receive a top level part number from the bar code reader attached to the host PC.  Use the page taped above the ventilation hood's sliding front door, to scan "AG04" among the five or six codes there.
 
  
−
Confirm that "AG04" appears in the main window's upper line edit box. If there's an unknown part number scanned, this line edit will show the brief message "Unknown type".
+
Specific project questions . . .
  
−
Once the part number AG04 is accepted, seat the sensor module in the fixture and close the lid.  When the lid is closed, the GUI will take a resistance reading across appropriate test points of the sensor module, and will indicate whether a correct matching ID is detected.
+
Work at MSX:
  
 +
  (1)  Can you talk a bit about your role in the medical wrist device firmware project at MSX?
  
−
If all is working at this point the main window's 'start' button will become enabled, text turning full black from grey in color. Click the start button once.  Now note the messages which appear in the controlling terminal.  There will be a lot of informational and diagnostics messages.  At some point in the first twenty seconds or so, there will appear a line or two of text indicating "STUB ROUTINE FOR AG04 SENSORS".  When you get this far, you're poised to start making code additions to the new calibrating routine.
+
  (2) Can you describe the tools and work steps, generically ok, in your CNC machine firmware debugging?
  
  
  
−
=== [[#top|^]] to edit ConfigTable dot csv ===
+
Summer Project question:

  (3)  Does the algorithmic project assignment work involve primarily or solely software design and testing?  Or any hardware?

To edit ConfigTable.csv any text editor will do.  The key features of this file are:
+
  (4)  Looks like there's a lot of documentation in your summer project.  Do you like to document your own personal projects, such as things you may share on github or just have time to pursue on weekends?
  
−
* comma-separated values lines
+
  (5) In a sentence or two how would you briefly summarize what each of "requirements", "specifications" and "test plan" mean?
−
*  comment lines
 
−
*  blank lines
 
  
−
The Gas Platform Unified Tester has a small parsing routine which ignores blank lines, and lines which begin with the character '#'.  Near the top of the ConfigTable.csv file there are some fifty comment lines, one per field numbered and named per comment line.  Actual "live" stanzas which express the data of these fields for each Gas Platform sensor type, and main board type, are the lines in comma-separated value format.
+
-->
  
−
The resistor ID field lies somewhere between or near the range of fields 10..15.  When reviewing the meaningful stanzas (records) themselves the resistive IDs are nearly the only values which are integers and in the ranges of about 2200 to 30000.
+
<!--
  
−
When changing a value here, it is a helpful practice to add a comment line above the record you're changing, to annotate the change. It's also good practice to copy the line you must change. The original line can be commented out, preserving the record as you found it.  The copy of the line then becomes the one that's live and that you edit.  A modification like this would look like,

This kind of non-destructive amending is helpful to those of us working directly on the task at present times, and also to future project contributors.  I often comment lines to be changed this, because I don't necessarily know what can safely be deleted.  When in doubt, comment it out.
