I almost said Ruby Rogues. How tired am I? JAMISON:  Don't cheat on us, Chuck. CHUCK:  It's right after Christmas. JAMISON:  We know you have another family but we love you when we have you. CHUCK:  Oh, my gosh! Yeah, we had family here for two days and my wife panics when people are coming over and has to have the house immaculate. And then she kept getting tired or sick or having some other issues. So, I kept forcing her to go to bed and then staying up until 2:00 AM, cleaning the house. So, I’m totally worn out. Anyway, so this is JavaScript Jabber, it's not Ruby Rogues. If you want Ruby Rogues, go to RubyRogues.com and see what we were talking about over there. Last week, we talked about conferences and I know that AJ wanted to say something. I guess we usually do the introductions first. So, let's do that and then let AJ say his piece and then we’ll move onto our topic for today. So, this week on our panel, we have Jamison Dance. JAMISON:  Hi, guys! Merry Belated Christmas. CHUCK:  We have AJ O'Neil. AJ:  Yo! Yo! Yo!  Coming at you from the green Christmasphere of Virginia. CHUCK:  Oh, you're in Virginia? AJ:  Yes, I am. Visiting family. CHUCK:  Cool. And I'm Charles Max Wood from DevChat.tv. I just want to put a quick plug in for my Rails course. If you want to learn Ruby on Rails, go to RailsRampUp.com. It's kind of a guided course and you get a lot of access to me to learn it. So AJ, what was it that you wanted to chime in with, with the conferences that we couldn't get you in last week to say? AJ:  Okay. So, both Merrick and myself have had this same experience. So, we were talking about having the broad conference versus the focused conference, the broad talk or workshop versus the more focused one. And we both have come to the conclusions that having it more focused is better. With the conference, it's fun to go to a broad conference but even in that, like it’s nice to have the focused talks like the ‘Utah Open Source Conference’ which this year is ‘Open West Conference’. It's expanding out and they've got some big surprise. I'm guessing they got some nice speakers. And the call for papers for that opens on January 2nd supposedly. So, that's a really nice conference but it's broad but it’s still fun.

CHUCK:  Jake, do you want to introduce yourself for the folks who haven’t heard of you before? JAKE:  Sure thing. I work on the Google Chrome team as part of DevRel. What I’m doing there is a combination of speaking at conferences about particular stuff. I got to do a lot in performance at the moment, but I also do a lot of standards work where I’ve done a lot with an alternative to application cache, which we’ll be talking about, but also looking at things like script loading and some of the resource priority stuff. CHUCK:  Cool. So it sounds like you’re smart on a number of levels then. JAKE:  Or dumb at all. [Chuckles] I can only see what I work on. I don’t know if I’m any good at it. [Chuckles] CHUCK:  So we brought you on to talk about the application cache. I’m not completely sure I know what is totally involved there. Is it just the cache like you clear the browser cache cache or is it something else? JAKE:  Well. the aim for the application cache was to let you make a site that works offline. So we’ve got the http cache and that works, in a manner of speaking. But if you have, say a website where you’ve cached your JavaScript, you’ve cached your CSS. You’ve cached your html page and some images. That’s great, but the user will visit another website and the browser will go and delete the CSS file from your site from the cache just to make room for the stuff from this other site. That means that if we were just going to use the http cache for making things work offline, people go to your site, your html’s there, your images are there, your JavaScript’s there, but your CSS is not and that’s going to break your site.

The panelists talk to Bart Wood about large single page JavaScript applications.

Episode Summary

Rene is a software developer for ESRI and works in spatial and mapping software. ESRI has been around since 1969 and has seen their work explode since they shifted to providing address and location services. Rene talks about how he thinks about location and mapping when building software around it and things that he has to approach in unique ways. The panel discusses some of their past experiences with location software. Some of the most difficult aspects of this software is changing time zones for data and actually mapping the Earth, since it is not flat nor a perfect sphere. Rene talks about the different models used for mapping the Earth.

Most mapping systems use the same algorithm as Google maps, so Rene talks about some of the specific features of ArcGIS, including the ability to finding a point within a polygon. Rene talks about what routing is, its importance, and how it is being optimized with ArcGIS, such as being able to add private streets into a regular street network.

The panel discusses how the prevalence of smartphones has changed mapping and GPS and some of their concerns with privacy and location mapping. One thing ESRI is very careful about is not storing private information. Rene talks about the kinds of things he has seen people doing with the mapping and location data provided by ArcGIS, including a Smart Mapping feature for developers, mapping planets, indoor routing, and 3D models.

This case report describes bilateral calcified coronary aneurysms with a significant proximal left anterior descending and right coronary artery stenoses immediately distal to the aneurysms.

To the Editor We read the recent article by Klauser et al with great interest. While the potential implications of the findings are exciting, we have several concerns. First, the authors do not explicitly state whether electrocardiogram gating was used in their study. This is an important detail because cardiac motion artifact is a source of artifactual coloration with dual-energy computed tomography (DECT), particularly with dual-source scanners given the approximately 80-millisecond temporal difference between the 2 radiography beams. Furthermore, beam hardening artifact from calcified atheromas and partial volume effect, known sources of artifacts in the 2-material decomposition algorithm of DECT, may largely explain the findings. While patients with gout had higher prevalence of coronary calcification (55 of 59 patients [93%]) and cardiovascular monosodium urate (MSU) deposition (51 of 59 patients [86%]) than controls, the authors do not report whether the 4 patients with gout without coronary calcifications exhibited MSU deposition nor the number of controls or cadaveric hearts with coronary calcification. The images from the article show areas of green pixelization occurring adjacent to calcified plaques on grayscale computed tomography images (eg, Figure 2A and D, left anterior descending artery [yellow arrowhead]), which would favor this artifact hypothesis without additional data.

In Reply We appreciate the valuable comments of Becce et al on our article. We applied prospective electrocardiography gating using a thin-slice cardiac protocol to ensure highest spatial resolution with minimal motion artifact. A noncontrast electrocardiography-gated computed tomography (CT) examination with standardized scan parameters was performed using a 128-slice dual-source CT (SOMATOM Definition Flash; Siemens) with a detector collimation of 2 × 64 × 0.6 mm, rotation time of 0.28 seconds, and prospective electrocardiography triggering for heart rates less than 65 beats per minute (diastolic padding, 70% of RR interval) and more than 65 beats per minute (systolic padding, 40% of RR interval). Axial images were reconstructed with 0.75-mm slice width, increment of 0.5, and a medium-smooth convolution kernel (B26f). When motion artifact was present, it was distinguished by visual analysis of an experienced observer and colorized pixels related to motion were excluded.

This cross-sectional study investigates whether hospital inpatient percutaneous coronary intervention volume is associated with rates of 30-day risk-adjusted mortality and hospital readmission after transcatheter aortic valve replacement and transcatheter mitral valve repair.

Lowering low-density lipoprotein cholesterol (LDL-C) levels remains a mainstay of cardiovascular disease prevention, but gaps in treatment remain, even in persons with hypercholesterolemia and greatly elevated LDL-C levels. Although well-described gene variants in the apolipoprotein B (APOB), low-density lipoprotein receptor (LDLR), and proprotein convertase subtilisin/kexin type 9 (PCSK9) genes explain small but important fractions of monogenic hypercholesterolemia, recent attention has turned to prognostication of cardiovascular disease using polygenic risk scores (PRS) that incorporate common genetic variants derived from large-scale genome-wide association studies of lipid subfractions. Earlier PRS considered only variants with genome-wide significance, and newer studies have focused on methods that better capture the variance conferred by millions of variants, suggesting an ability to identify risk equivalent to monogenic mutations. There remains a gap in evidence from prospective observational studies or treatment trials regarding the appropriate placement of PRS in risk assessment and lipid treatment decisions relative to information on rare monogenic gene variants, particularly in multiethnic populations.
