kandi X-RAY | impose Summary

impose is a Ruby library typically used in Editor, Document Editor applications. impose has no bugs, it has no vulnerabilities, it has a Permissive License and it has low support. You can download it from GitHub.

PDF::Impose is a utility and library for reformatting PDF files, in order to lay out multiple pages of the original document on a single page. The original pages are arranged in such a way that the new page may be folded and cut to produce a signature--a small booklet in which the pages are in the expected order. In this way, an existing PDF can be printed, folded, cut, and bound into a handmade book or booklet. This process of laying out pages in this way is called imposition.

            The post meta hasn't been registered on the curriculum-vitae post type, so WordPress isn't able to update it. WordPress is trying to update it because the PluginDocumentSettingPanel is still being rendered on the curriculum-vitae post type.

            I usually do a check of the post type before working with any custom post meta or adding any PluginDocumentSettingPanels for that post type:

            Regex needed to match a proper currency format of whole numbers, and set maximum dollar value
            Asked 2021-Jun-05 at 17:41

            all, Im trying to create a regex that enforces:

            1. whole numbers only, no decimals/fractions
            2. thousands separated by commas
            3. sets a maximum value allowed. Acceptable range of 1-25,000,000,000 (25 billion)

            I created the following regex that already accomplishes the first 2 requirements, only allowing acceptable values like: 1 1,000 25,000 250,000,000 etc.

            but it's the 3rd requirement of setting a maximum value of 25 billion that I'm struggling with.

            ANSWER

            Answered 2021-Jun-05 at 14:47

            You can add domain knowledge or constraints to structure learning in a couple of ways.

            • If you want to specify the network structure and parameters using domain knowledge, you can build the network manually using custom.fit.

            • If you want to estimate the structure of the BN from data then you can impose constraints on edge direction & edge presence using the whitelist and blacklist parameters in the structure learning algorithms.

            • A prior can be placed on the edges in structure learning (e.g. prior="cs", where "If prior is cs, beta is a data frame with columns from, to and prob specifying the prior probability for a set of arcs. A uniform probability distribution is assumed for the remaining arcs."). There are other priors that can be used.

            Ceres Solver: how to define bounds/constraints?
            Asked 2021-Jun-04 at 12:31

            Ceres solver states everywhere that it can

            [...] solve robustified bounds constrained non-linear least squares problems

            and that it supports upper and lower bounds constraints on the parameter blocks (for example in http://ceres-solver.org/modeling_faqs.html it states Ceres Solver only supports upper and lower bounds constraints on the parameter blocks), but somehow I can't find anywhere in the documentation how I can set these upper and lower bounds.

            So, how do I set upper and lower bounds for parameter blocks in ceres solver?

            Specifically, how do I do that in an AutoDiffCostFunction? If I use if statements to return a very big residual out of bounds, then that function isn't differentiable.

            The problem is that Apache doesn't 'link' Proxypass / http://example.com and - even though they both try to work with /. This means that Proxypass is handling requests for '/' first, and the Location section is never being used.

            ANSWER

            Answered 2021-Jun-01 at 17:26

            Your approach does not work. The correct approach is this:

            • Unless you are a performance expert (which is hard to become), do not make assumptions about what kind of code performs well vs. performs poorly, and maintain skepticism when analysing profiler reports. This is not particularly useful advice (it boils down to: A profiler report may be lying to you!), but it is what it is. Effectively, either be a performance expert, or accept that there's not much you can do about it. Sucks, but, don't shoot the messenger.
            • Write idiomatic java code. It is easiest to maintain and most likely to get optimized by hotspot.
            • Reduction of algorithmic complexity is useful and should always be the first thing you check. To some extent, an optimization that reduces algorithmic complexity gets to ignore the first rule. You do not need to be particularly up to date on the vagaries of JVMTI or Flight Recorder and how profilers work to conclude that an algorithmic rewrite is worthwhile and is going to significantly improve performance.
            • do not trust pithy rules of thumb, no matter how many people are saying it. Do not look for 'easy to apply patterns' like 'replace all foreach loops by appending an if-block that tests for empty first' - these are essentially never correct and usually reduce performance.
            • Be aware that bad performance advice is rampant. You should never treat ubiquitous presence of some argument otherwise bereft of proof or research as "that makes it more likely to be true" as a general principle in life and logical reasoning (it is, after all, a logical fallacy!), but this counts double for performance!
            More in-depth musing

            Presumably, you're not going to trust the above maxims just because I'm telling you to trust them. I'll try to take you through some falsifiable reasoning to show you why the above maxims are correct.

            In particular, this idea of checking for empty first seems extremely misguided.

            Let's first translate the overly hyperbolical and therefore rather useless well-known maxim premature optimization is the root of all evil into something more tangible:

            Do not make your code an ugly, caveat-ridden mess of weirdness because of an imagined performance issue.

            Why can't I go by often-heard maxims?

            Do not go by "people" here. Because "people" are notorious for being utterly wrong on performance, time and time again. If you can find widespread, pithy and entirely bereft of proof or research statements that X is good or bad for performance, you can rest assured in the thought that this means absolutely nothing whatsoever. Your average joe twitter writter or whatnot is a clueless idiot in this regard. Proof, ample research, or credentials are an absolute requirement to take things seriously, preferably 2 or 3 of those. There are lists of well known performance falsehoods (commonly held beliefs about how to improve JVM performance that absolutely do not help whatsoever and often actually hurt), and if you then search for these falsehoods you can find entire hordes of folks who espouse it, thus proving that you just cannot trust anything based solely on the fact that you "keep hearing it".

            Note also that for just about every imaginable line of java code, you can come up with 100+ plausible if somewhat exotic ideas on how to make the code less obvious but seemingly 'more performant'. Clearly then you can't apply all 100 variants to every line in the entire project, so the road you were planning on taking here ("I do not quite trust that profiler, I find it plausible escape analysis will fail to eliminate this iterator allocation, so, just to be safe I will add an if that checks for empty first"), ends in a disaster where even the simplest task becomes a many-lined, seemingly excessively redundant soup. And performance will be worse on average, so it's a lose-lose scenario.

            Here's a simple example to drive the point home, and you can watch those presentations by Doug for more of this sort of thing:
