And, NASA APOD with its ancient HTML, absent even CSS classes or IDs to select, does not help matters. Normally, bash would continue executing the script even if some of the commands fail. Even though it is milder than some other compounds, it can still be irritating, particularly on damaged or allergy-prone skin. His line of shoes, Air Jordans, is still successful today, and he now owns and operates the Charlotte Hornets. 1 API call. The text of the most recent notice is extracted from the JSON response using jq, the command line JSON processor. Parsing of the downloaded HTML was done using pup. This can be obtained using Really Simple Discovery. The bottle contains two chambers, as detailed in this Agence-France Presse article, one for the Champagne and the other for a valve that uses the carbon dioxide in the Champagne to eject foamy little alcohol spheres, which can then be scooped into long-stemmed glasses for sipping. From the response JSON, which contains a lot of things, the text of the notice and the publishing time are extracted and printed. If the notice we are about to publish is the same as the notice previously published, the script aborts.
The -e flag tells bash to abort the script if any command fails. If the links do not exist, wget will exit with an error, and bash will abort the script. This is useful because if any of the network operations fail due to lack of connectivity, we want to safely abort the script and not blindly ply on. URL which we reference several times later in the script. If the script is run more than once a day, this duplicate notice check ensures that the same picture does not get posted several times. The -spider flag makes wget only check for the existence of the link and not waste bandwidth downloading it. HTML. I didn’t want to make a mess downloading the HTML page into a file, and thought capturing it in a variable was cleaner. Once we have extracted all required information, we construct the GNU Social notice in a variable. Keep an open mind when thinking about the positives of your job; you may find that your work relationships are meaningful to you and developing them fires up your creativity and desire to collaborate, or that the work you’ve chosen allows you to have a greater quality of life outside of work.
As the United States Postal Service undergoes its fiscal crisis in the second decade of the 21st Century, it is well to note that these are not entirely new problems. Abstracts and full-text of major astronomy and physics publications are indexed and searchable through the new ADS modern search form as well as a classic search form. The Astrophysics Data System (ADS) is a digital library portal for researchers in astronomy and physics, operated by the Smithsonian Astrophysical Observatory (SAO) under a NASA grant. ADS maintains three bibliographic collections containing more than 15 million records covering publications in astronomy and astrophysics, physics, and general science, including all arXiv e-prints. In addition to maintaining its bibliographic corpus, ADS tracks citations and usage of its records to provide advanced discovery and evaluation capabilities. We currently have links to over 13.3 million records maintained by our collaborators. Then, we have some settings put into bash variables.
We start with the usual bash shebang. We also make sure we have extracted the links properly and that they actually exist. But, the NASA APOD RSS feed only has links to scaled down thumbnails, and not the full images. There is a NASA APOD RSS feed however. “Many space exploration problems require that high-density power be available at all times, and there is a class of such problems for which nuclear power is the preferred – if not the only – option,” Rex Geveden, a former Nasa associate administrator and CEO of the power generation company BWX Technologies, told the National Space Council in August. However, our journeys to space have been limited by the power of chemical rocket engines and the amount of rocket fuel that a spacecraft can carry. While the probes have left the heliosphere, Voyager 1 and Voyager 2 have not yet left the solar system, and won’t be leaving anytime soon. RSS, being XML is more machine readable and might have been good. Decades later, the photographer found himself at the same launchpad, watching it being prepared for a mission to Mars. However, the Columbia disaster resulted in additional orbiters being prepared for launch on need in the event of a rescue mission.
