Cheers to 2023

2023 was a memorable year and quite the ride! Eventful and full swing on so many fronts. Here’s the annual rundown:

Saliva Drug Test: Understanding the Basics

pygeoapi: two releases, lots of development at code sprints and continuous improvement for the project. Dutch API rules, CRS and increased support for the various standards as they evolve. As well, numerous valuable discussions this year around hardening the project for the long term. Contributions (always valued!) continue to increase, which shows a healthy project with considerable interest.

Saliva drug testing is a common method employed to detect the presence of various substances in an individual’s system. It involves collecting a sample of saliva, typically through swabbing the inside of the mouth, and analyzing it for the presence of drugs or their metabolites.

How Saliva Drug Tests Work

The collection process for saliva drug tests is relatively straightforward. A swab is placed inside the individual’s mouth, usually between the cheek and gums, for a few minutes to collect the saliva sample. This sample is then analyzed to identify the presence of specific drugs. Saliva drug tests are known for their shorter detection window compared to other methods like urine or hair testing, typically ranging from a few hours to a couple of days, depending on the substance.

Advantages of Saliva Drug Tests

One of the primary advantages of saliva drug tests is their non-invasive nature. Unlike blood tests, which require a needle stick, or urine tests, which necessitate providing a sample in a restroom, saliva tests can be conducted quickly and conveniently with minimal discomfort to the individual. Additionally, results are often available within a shorter timeframe, making them a preferred option in situations where rapid testing is required.

Limitations of Saliva Drug Tests

Despite their convenience, saliva drug tests do have some limitations. The detection window for these tests is relatively short compared to urine or hair tests, meaning they may not detect drug use that occurred outside of this window. Additionally, saliva tests are generally less sensitive than other methods, making them more prone to false-negative results, especially for substances with low concentrations in saliva.

Industries and Applications

Saliva drug testing is utilized across various industries and applications. In the workplace, employers may conduct these tests as part of pre-employment screening or random drug testing protocols to ensure a safe and drug-free environment. Law enforcement agencies may also use saliva tests during roadside sobriety checks or as part of criminal investigations. Additionally, rehabilitation centers may employ saliva testing to monitor individuals undergoing treatment for substance abuse.

Factors Affecting Test Results

Several factors can influence the results of a saliva drug test, including the frequency and dosage of drug use, individual metabolism variations, and the type of drug being tested for. Factors such as dehydration or oral contamination can also affect the accuracy of the results.

Accuracy and Reliability

While saliva drug tests offer numerous advantages, including ease of administration and rapid results, their accuracy and reliability can vary depending on various factors. Compared to other drug testing methods such as blood or urine tests, saliva tests may be less sensitive, particularly for detecting drugs with low concentrations in saliva. However, advancements in technology continue to improve the accuracy and reliability of saliva drug testing.

Legal Implications

In legal contexts, the admissibility of saliva drug test results may vary depending on jurisdiction and specific circumstances. While these tests can provide valuable evidence of drug use, they may also raise concerns regarding employee rights and privacy. Employers must adhere to relevant laws and regulations governing drug testing in the workplace to ensure fairness and compliance.

How to Prepare for a Saliva Drug Test

To obtain accurate results from a saliva drug test, individuals should take certain precautions. This may include avoiding the use of certain substances leading up to the test, maintaining good oral hygiene, and staying hydrated. Following these guidelines can help minimize the risk of false-positive or false-negative results.

pycsw: lots of improvements on standards support (OGC API – Records, STAC) as we move towards version 3.0. The project supports so many discovery API standards, and we are not done yet 🙂

OGC: development on numerous standards: OGC API – Records, and OGC API – Environmental Data Retrieval and Pub/Sub went though a number of improvements and updates in 2023. I was also fortunate to help deliver the OGC API workshop as part of the GISE Hub Winter School on OGC Stack (which included delivery of the Diving into pygeoapi workshop as well).

OSGeo: I’m happy to report that the ZOO-Project passed incubation and became an official OSGeo project! A big congratulations to Gérald and team. We also had a successful joint sprint with OGC as well as the first in-person OSGeo Community Sprint since 2019, in November. The annual FOSS4G global event in Prizren was fantastic, and I was happy to provide two workshops, numerous presentations and a keynote. I continue to serve on OSGeo’s Board of Directors and was happy to help move forward the OSGeo / OGC collaboration piece in 2023.

WMO: the WIS2 standards and architecture were put through a pilot phase this year. WIS2 specifications, guides, manuals all received significant updates this year thanks to the contributions of many experts. Most specifications also have reference implementations (wis2box, wis2-gdc, wis2-gc, pywis-pubsub, pywis-topics, pywcmp, etc.). The series of WIS2 training sessions also proved valuable for numerous members in implementing WIS2 technologies. Did you know that wis2box now has 30 or so deployments worldwide?

MSC GeoMet: the national weather/water/climate API platform continues to grow. We’ve recently added GOES imagery, and MSC AniMet is emerging as a great tool for visualization of our API!

Health: another year (circa 2012) of not smoking. I am hoping to shape up again in 2024, let’s see how it goes.

Looking forward to 2024:

  • pygeoapi: RFC2 will help harden things as we move towards 1.0. As well, look for news soon on the first ever pygeoapi code sprint 🙂
  • pycsw: moving towards 3.0, look for a new YAML-based configuration format, as well improvements on faceting, distributed search, harvesting and more
  • OGC: look for OGC API – Records to be released, as well as Pub/Sub development in EDR and beyond. The annual joint sprint with OSGeo will also take place in Évora, Portugal on 26-28 February. See you there!
  • OSGeo: the global event in Belém (December) promises to be a can’t miss event, and I look forward to providing presentations and training on Geospatial Python, pygeoapi and OGC at the event
  • WMO: 2024 is the year that the architecture and specifications are ratified as we move into the pre-operational phase

Wishing everyone a safe and happy 2024!
