One problem—not a fatal one, but still an issue with any virtual DOM—is that embedding SVGs directly into your app can be a resource hog. No matter how much you compress, no matter how logical and streamlined your components, if you need to load up hundreds of very-complex SVGs, React will need to track all of their nodes, and updating them becomes a chore.

How do you leverage browser cache when Google’s very own Analytics.js has it’s expiry time set to 2 hours? How do you minimize DNS requests when Google advices you to copy their tracking code, linking to an externally hosted Javascript file?If that isn’t bad enough already, Google’s advice is to avoid hosting the JavaScript file locally. And why? To ensure you get access to new features and product updates.
-
Why should I host analytics.js locally?The Complete Analytics Optimization Suite for WordPress gives you the best of both worlds. After activation it automagically downloads the latest version of analytics.js from Google’s servers, places the necessary tracking code in your WordPress theme’s header and keeps the local Javascript file up-to-date using an adjusted version of Matthew Horne’s update analytics script and wp_cron(). This way you can minimize DNS requests, leverage browser cache, track your visitors and still follow Google’s recommendation to use the latest features and product updates.

I would like to make an appeal to core developers: all design decisions involving involuntary session creation MUST be made with a great caution. In case of a high-load project, avoiding to create a session for non-authenticated users is a vital strategy with a critical influence on application performance. It doesn't really make a big difference, whether you use a database backend, or Redis, or whatever else; eventually, your load would be high enough, and scaling further would not help anymore, so that either network access to the session backend or its “INSERT” performance would become a bottleneck. In my case, it's an application with 20-25 ms response time under a 20000-30000 RPM load. Having to create a session for an each session-less request would be critical enough to decide not to upgrade Django, or to fork and rewrite the corresponding components.

String composed of these characters are interned. Aka the following will not be interned:
f = 'f o'but the following will be interned:
f = 'f_o' -
sequences generated through peephole optimization are discarded if their length is superior to 20
So values generated via peephole optimization above 20 are not 'pre-computed' but left as is:
'a' * 21 # remains in the byte code where as 'a' * 20 # gets converted to 'aaaaaaaaaaaaaaaaaaaa' -
string subclasses cannot be interned
Meaning
class NewString(str): pass assert NewString('f') is 'f'Will fail. Where as:
f = 'f' assert f is 'f'Will pass.
This is presents a case for not building custom string types in Python as it breaks the string cache and can result in a performance hit.
-
strings can be compared by a O(1) pointer comparison instead of a O(n) byte-per-byte comparison
This is a huge advantage. Not only does it save memory by not duplicating simple and common string values, but the comparison method has an early exit that compares the pointers instead of the values. aka in sudo-code form:
// compare pointers if self._value is value: return True // compare values for i, v in enumerate(self._value): if v != value[i]: return False return True

This is especially true for online gaming
WASM is being used to run many demanding applications directly in the browser. Autocad is one important example where architects can use this application without installing a usually very heavy piece of software on their computers. They can access the Autocad suite from almost any computer only by logging into to a website. It is expected that a large part of the gaming industry will shift this way as well as many other services. One of the main advantages of this approach aside from a lack of a local installation is real-time software updates for any number of users. A new model of software building and execution will be based on WASM. WASM is also very good for blockchains. Search for the WASM section to learn more.

“Public performance measurement systems often have unfortunate or disastrous unintended consequences. Most recently, a pay-for-performance scheme at the Veterans Health Administration (V.A.) led to falsified wait-time records and care so delayed that, in some cases, patients died awaiting medical attention. Twenty-five years of studies have shown that “pay-for-performance” doesn’t work in either the public or private sector: such systems smother creativity, crowd out intrinsic motivation and invite gaming and generally fail to achieve intended results.”

Locke argues that all ideas arc mental combinations of sense perceptions and 1hat words refer not directly to things but to menial phenomena, the ideas we retain and build from sense impressions.
Like Locke, Karen Barad is pushing against the idea of words as representational of things, with her performative model?
"A performative understanding of discursive practices challenges the representationalist belief in the power of words to represent preexisting things" (Barad 802).
In what ways does performance differ from "mental phenomena"? Mental = internal only where performance = internal and external?

challenges the positioning of materiality as either a given or a mereeffect of human agency.
I'll be the first to admit I wasn't able to follow all of what Barad is tackling here, but I'll take a stab at a summary: Barad argues that we need to bring matter/the material into our concepts of rhetoric, agency, and performance--to not bind these issues only to the human but to see them posthumanly, to leave behind the assumption that these concepts can only be 'wielded' or conducted by humans.

performativity isactually a contestation of the unexamined habits of mind that grant lan-guage and other forms of representation more power in determining ourontologies than they deserve

This article explores the interaction of student based learner-centered used of technology tools such as wikis, blogs and podcasts as new and emerging technology tools. With distance learning programs becoming more and more popular, software applications such as Writeboard, InstaCol and Imeem may become less of the software of choice. The article looks closely at the influence of technology and outcomes.

One is the linked list of lines you mention. I believe this is intended to solve a display problem that TECO (the original language in which Emacs was implemented) had solved differently using the "gap" data structure. The fundamental issue was that if you have a buffer represented as a single block of contiguous text, then insertion on a character-by-character basis can be O(n2), each time you insert a character, you have to copy the entire subsequent buffer over one space.

Companies that try to make the same standards across their organization, will cause their people to get bogged down in trying to to make the standards fit their job function. This causes to many constraints and will lower project performance.

To summarize: without queuing mechanism: same Erlang node: 5.3 million messages/min; different Erlang nodes: 700 K messages/min. with queuing mechanism: same Erlang node: 5.3 million messages/min; different Erlang nodes: 2.1 million messages/min. The complete code to run this on your machine is available here. This whole ‘queuing idea’ is still an experiment, and I’d be more than delighted to hear your feedback, to see whether you are getting the same results, you know how to improve the concept or the code, or you have any considerations at all you would like to share.
I got here from the discord blog on how they optimized their performance and it looks like the trick is to batch messages when sending to remote nodes. Seems kinda obvious though that batching messages would improve performance.
A trick to keep in the back pocket.

Duncombe was frustrated by the liberal left’s insistence on using dry logic to make political arguments. He looked to the political right and far left as groups that fostered affective fantasies. To him, an “ethical spectacle” is participatory fantasy that is open-ended, transparent, and performative (Duncombe, 2007, p. 17). Duncombe saw ethical spectacles as directly democratic, breaking down hierarchies, fostering communities, and encouraging diversity. He held a strong form of participation, as participants in a spectacle “must also contribute to its construction” (Duncombe, 2007, p. 127). The civic
imagination is activated and becomes visible through communication because it is intrinsically linked with spectacle, action, and performance
Acá quizás lo que mejor podría funcionar sería el caracter celebratorio del encuentro, particularmente en Latinoamérica. Habría que contrastar la lógica de los grandes espectáculos con la idea de la celebración a pequeña escala.

At least since Doug Engelbart’s “mother of all demos” the introduction of new products has been accompanied by showmanship. Demonstrations are theater where possible uses for technology are presented (Smith, 2009). Hackathons have been argued to be the “front stage” for data and can be contrasted with the murky “back stage” of data production, munging, and interpretation (Gregg, 2014b). The difference with Balsamo might be that she does not put performance in scare quotes.
Esto conecta las ideas de boostrapping vía infraestructura, de Engelbart, con la idea de demo como performance (espectáculo, obra viva) y la inversión infraestructural de Star, al traer al frente aquello que está al fondo (la producción de datos y su uso).

“performance of innovation” (Balsamo, 2011) described how individuals collaboratively design technology in public settings. According to Balsamo, technology design emerges from a collaborative and cultural process that she terms "technoculture." Innovations are not objects, but like technology they are, “assemblages of practices, materialities, and affordances” (Balsamo, 2011, p. 8). Through performance and embodied action, technocultural innovation has a “dual logic”: the expression of the technological imagination and cultural reproduction.

the point of view appears to equate 'Elvis' presence at security as a negative, but it is never fully presented as to the reason, though it may be an undertone of intimacy throughout or that the POV actually knows this 'Elvis' and would rather avoid him.

For some reason, no one ever seems to thing of this... but it has always worked for me... Have you tried unchecking Use hardware acceleration when available at the bottom of chrome://settings/ (advanced area)?
This worked for me when Chrome was freezing every time I loaded a page. I was seriously worried I had a rootkit or key logger that I couldn't detect!

Time to iterate over an array of 100,000 integers
so looks like firefox takes more time to iterate through underscore _.each compare to chrome difference is atleast 10 times

The downsides are that Firefox has slower startup times (because Chrome is constantly on in the background) and slower page loading speeds (because it doesn’t steal CPU cycles like Chrome).
So this is why firefox i slow?

"Research suggests that avoidance of challenge may be related to motives and goals in somewhat complex ways. Elliott and Dweck (1988), in an experimental study, found that when children were oriented toward mastery goals they were more likely to choose tasks described as challenging and offering opportunities to learn, regardless of their level of perceived ability. But when students were oriented toward performance goals, they chose challenging tasks that served to enhance others' high opinions of their abilities only if they perceived their ability to be high. Children who perceived their ability to be low and were oriented toward performance goals, in contrast, tended to choose tasks described as easy but that would avoid unfavourable judgments of their ability. Some students may feel they are in a double-bind, preferring easy work that does not threaten their self-worth, yet taking on difficult tasks in order to demonstrate their competence or superiority... Elliot and Church (1997) found that performance-approach goals were positively associated with measures of both challenge-avoidance (fear of failure) and challence-seeking motives (achievement motivation). Avoidance of challenge, then appears, to be positively associated with performance-avoidance goals and negatively related with matery goals, but may have a more complex relationship with performance-approach goals."
In other words, the goal has to be to focus teaching and evaluation on the inculcation of mastery goals and the avoidance of situations in which students are encouraged to engage in performance-avoidance. Once they start engaging in performance avoidance, they then stop seeing challenge.

"...when students self-handicap, cheat, fail to seek help when they need it, and avoid the types of challenging and novel academic tasks that produce real learning, they are undermining their own learning and development. Over time, such behavior can produce a self-perpetuating cycle of academic failure and increased avoidance (Zuckerman, Kieffer, and Knee 1998)."

- Gheen and Midgley 1999 looked at classroom practices of sharing information about student work:
- Where work was shared to "see who got the right answer" (relative ability purposes) and
- to "get hints for when you have difficulty" (acquiring information purposes"
No surprise:
"They found that students' perceptions of the goal structure related to avoidance of novelty and challenge. When students perceived that their classrooms emphasized mastery goals, they reported lower levels of avoidance, but when they perceived their classrooms emphasized performance goals, they were more lilely to say that thei preferred to avoid novel and challenging work."

Achievement goals were important to changes in motivational constructs around the receipt of grades in the classroom. As expected, the effects of a per formance-approach goal on changes in motivational constructs were moderated by grades. When students received high grades, a performance-approach goal was unrelated to changes in self-efficacy, desire to avoid challenge, or intrinsic value. However, when students received low grades, a performance-approach goal was related to decreased intrinsic value and increased desire to avoid chal lenge. Thus, although a performance-approach goal does not seem to have draw backs in the context of success, there are drawbacks when students experience setbacks
When students achieved low grades, a performance approach goal was related to decreased intrinsic value and increased desire to avoid challenge.
-
in recent years, some researchers have concluded that it is only perfor mance-avoidance goals that have drawbacks and that performance-approach goals promote high achievement and do not affect motivation and engagement negatively
Performance avoidance is bad; performance approach motivation may be good.

Preference to avoid challenging work. Preference to avoid challenging work (4 items) assesses students' desires for easy, familiar tasks (Urdan, Ryan, Ander man, & Gheen, 2002). Sample items are "I prefer doing work that does not make me think too hard" and "I prefer assignments that I know I can do rather than those that are a challenge." The measure was found to be reliable in our sample (a at Time 1 = .85; Time 2 = .85)
Survey questions on preference to avoid challenging work
-
In summary, our main goal was to examine how students' achievement goals are related to changes in self-efficacy, preference to avoid challenge, and intrin sic value in the face of evaluation. Early in the semester, we assessed students' achievement goals, self-efficacy, desire to avoid challenge, and intrinsic value. We assessed students' self-efficacy, desire to avoid challenge, and intrinsic value again immediately after they received their grades on their first major exam or paper. This design allowed us to examine the role of goals in the change in mo tivational constructs associated with performance feedback. Our main hypothe ses were (a) a mastery goal will be associated with enhanced motivation around receipt of grades (i.e., increased efficacy and value and lower preference for chal lenge avoidance); (b) a performance-avoidance goal will be associated with di minished motivation around receipt of grades (i.e., decreased efficacy and value and increased preference for challenge avoidance); and (c) the effects of a per formance-approach goal on changes in motivation will be moderated by grades. When students encounter low grades, a performance-approach goal will be relat ed to diminished motivation. When students receive high grades, a performance approach goal will be unrelated to changes in motivation.
The method. Should see if I could replicate this.

Shim & Ryan 337 Furthermore, we expected a performance-avoidance goal to be associated with declines in motivational constructs, even in the context of high grades. A perfor mance-avoidance goal brings about negative achievement-related processes re garding evaluation. A performance-avoidance goal is associated with construing exams as a threat; incurring negative emotions, such as worry, fear, and anxiety; and the desire to escape exam situations (McGregor & Elliot, 2002). A perfor mance-avoidance goal, undergirded by a fear of failure, inherently involves a focus on a negative outcome (Elliot, 1999). With a performance-avoidant frame work, positive feedback is interpreted as "not failing" or "not being the worst." Al though such an assessment satisfies a performance-avoidance goal, it is unlikely to boost motivation, as the absence of something negative is not evidence of some thing positive. Thus, we expected a performance-avoidance goal to be associated with diminished motivation, regardless of whether grades are high or
Performance avoidance goals see exams as a threat, see failure as reflecting lack of ability, and positive feedback is interpreted as "not failing" or "not being the worst."

n recent years, some research has indicated that performance-ap proach goals are beneficial for achievement and do not affect motivation nega tively (see Harackiewicz, Barron, Pintrich, Elliot, & Thrash, 2002). In particular, when the approach versus avoidance nature of performance goals is considered, performance-avoidance goals are maladaptive, whereas performance-approach goals are often positively associated with achievement and show a positive or neutral relation to motivation
Performance approach goals are beneficial for achievement and do not affect motivation negatively, as opposed to performance-avoidance goals.
-
performance-approach goal has been positively associated with self-efficacy (Bong, 2001; Pajares et al; Skaalvik; Wolters, Yu, & Pintrich, 1996), desire to avoid challenging work (Meyer, Turner, & Spencer, 1997; Middleton & Midgley, 2002), and task value (Bong; Church, Elliot, & Gable, 2001; Wolters et al). However, some researchers have found no relation between a performance-ap proach goal and self-efficacy (Middleton & Midgley, 1997; Pajares et al.) or task value (Lopez, 1999; Tanaka & Yamauchi, 2001), so it is not clear whether this is always the case
Performance approach goals are positively associated with self-efficacy, but also to challenge avoiding behaviour.

udy, a mastery goal is positively associated and a performance-avoidance goal is nega tively associated with self-efficacy, challenge-seeking, and intrinsic value (Mid dleton & Midgley, 1997; Pajares, Britner, & Vahante, 2000; Skaalvik, 1997).
Mastery goals are positively associated with "self-efficacy, challenge-seeking, and intrinsic value"; performance avoidance goals are negatively associated with these same values.
-
contrast, a performance goal concerns a focus on demonstrating competence. Performance goals can be distinguished as either approach or avoidant (Elliot & Church, 1997; Middleton & Midgley, 1997; Skaalvik, 1997). A performance-approach goal concerns a focus on gaining favorable judgments of one's ability, and a performance-avoid ance goal concerns a focus on avoiding negative judgments of one's ability. Achievement goals represent disparate purposes for involvement regarding aca demic tasks and, as such, have been linked to different achievement-related processes and outcomes
Performance-approach goals focus on gaining a favourable judgement;
Performance-avoidance goal concerns a focus on avoiding negative judgements.
