However, work has become very hectic as I&#8217;m trying to juggle too many things all at once. There&#8217;s yet another round of revisions to do to the <a href=\"http:\/\/www.lookingatnothing.com\/index.php\/archives\/2359\">Round Robin paper<\/a>, people to interview and hire, projects to start, measurements to do, funding to apply for, and meanwhile, my publication list is looking frighteningly barren. Suffice to say, I&#8217;m currently in a state of constant, mild panic. Here&#8217;s hoping things will settle in place in the near future, but that brings me to the second item:<\/p>\n<p>Update frequencies: As you will have noticed, I&#8217;m not managing a post a week anymore. It&#8217;s reduced to one post per two weeks, partly due to my reduced time playing around with SAXS next to my organisational\/administrative duties, and partly due to the reduced &#8220;free&#8221; time I can spend on these posts. Nevertheless, I hope that the bi-weekly schedule will still be interesting! In the mean time, why not head over to ScienceOpen, and see <a href=\"https:\/\/www.scienceopen.com\/collection\/60b86265-20dc-4c92-8905-dd49e1075ed9\">the three SAXS-related collections there<\/a>!<\/p>\n<p>USAXS: I&#8217;ve been doing a little work on the <a href=\"http:\/\/www.lookingatnothing.com\/index.php\/archives\/2331\">USAXS instrument<\/a> as well, trying to figure out the control system. I was impressed by a brief <a href=\"http:\/\/www.tango-controls.org\/\">Tango<\/a> demonstration by <a href=\"http:\/\/www.lookingatnothing.com\/index.php\/archives\/2394\">Olivier Tach\u00e9 at CEA<\/a>, saw it running at Soleil, and so I think that is the way to go for this instrument. It requires network-connected device servers, which form a bridge between the devices (motor controllers, shutters, sensors, etc.) and a universal Tango protocol to be used over the network. In this way, you can connect anything and everything to a network, organize the devices, and address them from a controlling program.<\/p>\n<p>It&#8217;s not too easy a system to install and understand at first go, and it has too little &#8220;first steps&#8221;-documentation, but it will run on a <a href=\"https:\/\/www.raspberrypi.org\">Raspberry Pi<\/a> (the device servers at least), and Olivier&#8217;s being very helpful sending me hints to implement it. Once I get some more experience with it, I&#8217;ll share it with you.<\/p>\n","protected":false},"excerpt":{"rendered":"<div class=\"mh-excerpt\"><p>It is time again for some short items bunched together:<\/p>\n<\/div>","protected":false},"author":2,"featured_media":2455,"comment_status":"open","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"jetpack_post_was_ever_published":false,"_jetpack_newsletter_access":"","_jetpack_dont_email_post_to_subs":true,"_jetpack_newsletter_tier_id":0,"_jetpack_memberships_contains_paywalled_content":false,"_jetpack_memberships_contains_paid_content":false,"activitypub_content_warning":"","activitypub_content_visibility":"","activitypub_max_image_attachments":4,"activitypub_interaction_policy_quote":"anyone","activitypub_status":"","footnotes":"","jetpack_publicize_message":"","jetpack_publicize_feature_enabled":true,"jetpack_social_post_already_shared":true,"jetpack_social_options":{"image_generator_settings":{"template":"highway","default_image_id":0,"font":"","enabled":false},"version":2}},"categories":[1],"tags":[],"class_list":["post-2454","post","type-post","status-publish","format-standard","has-post-thumbnail","hentry","category-uncategorized"],"jetpack_publicize_connections":[],"jetpack_featured_media_url":"https:\/\/lookingatnothing.com\/wp-content\/uploads\/2017\/05\/1024px-Blek_le_Rat_-_Last_Tango_in_Paris.png","jetpack_shortlink":"https:\/\/wp.me\/p1gZ2v-DA","jetpack_sharing_enabled":true,"_links":{"self":[{"href":"https:\/\/lookingatnothing.com\/index.php\/wp-json\/wp\/v2\/posts\/2454","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/lookingatnothing.com\/index.php\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/lookingatnothing.com\/index.php\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/lookingatnothing.com\/index.php\/wp-json\/wp\/v2\/users\/2"}],"replies":[{"embeddable":true,"href":"https:\/\/lookingatnothing.com\/index.php\/wp-json\/wp\/v2\/comments?post=2454"}],"version-history":[{"count":2,"href":"https:\/\/lookingatnothing.com\/index.php\/wp-json\/wp\/v2\/posts\/2454\/revisions"}],"predecessor-version":[{"id":2458,"href":"https:\/\/lookingatnothing.com\/index.php\/wp-json\/wp\/v2\/posts\/2454\/revisions\/2458"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/lookingatnothing.com\/index.php\/wp-json\/wp\/v2\/media\/2455"}],"wp:attachment":[{"href":"https:\/\/lookingatnothing.com\/index.php\/wp-json\/wp\/v2\/media?parent=2454"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/lookingatnothing.com\/index.php\/wp-json\/wp\/v2\/categories?post=2454"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/lookingatnothing.com\/index.php\/wp-json\/wp\/v2\/tags?post=2454"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
