海外TECH	DEV Community	When numbers don't make sense	https://dev.to/miguelmj/when-numbers-dont-make-sense-10gi	When numbers don x t make sense IntroductionMost of the time basic arithmetic is pretty simple and intuitive Even working with powers and roots isn t that much of a headache However the IEEE standard for floating point numbers includes special values that can mess things up NaN Not a Number positive infinity and negative infinity In fact most algebraic properties of real numbers are no longer valid The only purpose of this post is to show some cases I found interesting where these values produce counterintuitive results Cover image by Armand Khoury from Unsplash Standard behavior of NaN and InfinityFor all x NaN gt x is false For all x NaN lt x is false For all x NaN x is false For all x NaN x is true For all x except NaN and Infinity Infinity gt x is true For all x except Nan and Infinity Infinity lt x is true Infinity Infinity NaNInfinity NaNInfinity Infinity NaNAny other arithmetic operation between a number and Infinity results in Infinity with a possible change of sign Any other arithmetic operation between a number or Infinity and NaN results in NaN Everything I will tell you from now is trivially deduced from understanding the list above in other words if you understand all its implications I won t tell you much new Anyway I think it is interesting to review some side effects that may escape from us when we don t keep them in mind Broken propertiesThe following is a non exhaustive list of properties that we use to expect while programming but are no longer true due to the existence of NaN and Infinity I will provide the statement of the property which doesn t hold and then a piece of code in JavaScript and Python that implements a check for it followed by a call that returns false Note JavaScript produces NaN and Infinity values easily not only because they are native values but because they result from regular operations Math sqrt or In the case of Python they are implemented in the math library math nan and math inf and operations that would produce them math sqrt or will raise an exception For this reason assume the following header in each Python snippet from math import nan infDisclaimer The snippets of JavaScript will also fail with values like strings or objects I m not trying to make any point about errors in JavaScript The point is about the NaN and Infinity values which belong to numeric types in any language with full support for the IEEE standard Now behold the fall of the tautologies IdentityLet s start with the most obvious and painful function identity x return x x identity NaN def identity x return x xidentity nan Some of the following are direct results of this A list can t contain elements that aren t equal to any elementSorry for the apparent redundancy in the statement check the examples to see what I mean function checkIncludesEqual arr x if arr includes x return arr some e gt e x else return true checkIncludesEqual NaN NaN def checkIncludesEqual arr x if x in arr return any x e for e in arr else return TruecheckIncludesEqual nan nan The max value of a list is greater than or equal to the restfunction checkMaxIsGE arr let maxVal Math max arr return arr every x gt maxVal gt x checkMaxIsGE NaN def checkMaxIsGE arr maxVal max arr return all maxVal gt x for x in arr checkMaxIsGE nan The min value of a list is lesser than or equal to the restfunction checkMinIsLE arr let minVal Math min arr return arr every x lt minVal gt x checkMinIsLE NaN def checkMinIsLE arr minVal min arr return all minVal lt x for x in arr checkMinIsLE nan Dividend equals divisor times quotientThis is the first we learn about division D d Q implies D Q d Well no more This example can only be shown in JavaScript because Python prevents division by zero function checkDdQ dividend divisor quotient dividend divisor return dividend quotient divisor checkDdQ checkDdQ Infinity The square of a value is greater than or equal to itselffunction checkSquareIsGE x return x x gt x checkSquareIsGE NaN def checkSquareIsGE x return x x gt xcheckSquareIsGE nan checkSquareIsGE inf Less than or equal to is equivalent to Not greater than I find this particularly disturbing not sure why function checkLEQisNGT x return x lt x gt checkLEQisNGT NaN def checkLEQisNGT x return x lt and not x gt checkLEQisNGT nan A value divided by itself equals onefunction checkBetweenSelfIsOne x return x x checkBetweenSelfIsOne NaN checkBetweenSelfIsOne Infinity def checkBetweenSelfIsOne x return x x checkBetweenSelfIsOne nan checkBetweenSelfIsOne inf A value minus itself equals zerofunction checkMinusSelfIsZero x return x x checkMinusSelfIsZero NaN checkMinusSelfIsZero Infinity def checkMinusSelfIsZero x return x x checkMinusSelfIsZero nan checkMinusSelfIsZero inf A value times zero equals zerofunction checkTimesZero x return x checkTimesZero NaN checkTimesZero Infinity def checkTimesZero x return x checkTimesZero nan checkTimesZero inf These last two have an interesting side effect too One would expect that x x and x to result in Infinity However when x is Infinity they result in NaN Don t you feel dizzy yet Bonus fun fact Hey while working on this article I found something interesting about square roots in Python As I stated earlier Python raises an exception if you try to compute the square root of a negative number But Python implements complex numbers natively so if you use the power operator instead it returns a valid result gt gt gt from math import sqrt gt gt gt sqrt Traceback most recent call last File lt stdin gt line in lt module gt ValueError math domain error gt gt gt e j The perfect result would have been j but due to floating point precision issues instead of you have a very very small number I hope you found it interesting too ConclusionSemantically sound code is much less prone to errors and reduces the need to be constantly catching exceptions I hope these examples have served as a reminder that we cannot neglect special numeric values or take for granted many seemingly intuitive properties that if overlooked can cause apparently correct code to exhibit undesired behavior	2023-03-09 16:30:00

海外TECH	Engadget	The best projectors you can buy in 2023, plus how to choose one	https://www.engadget.com/best-projectors-123004354.html?src=rss	The best projectors you can buy in plus how to choose oneHome theater projectors have come a long way from the clunky dim models of the past The latest models are brighter sharper more discreet and easier to install than ever They also deliver a picture size with image quality you could never get on a TV without spending a fortune With all that the best projectors are highly desirable for home theater buffs who want a true cinematic experience at home Over the last year we ve seen models bright enough to use in a normal room short throw models that take up very little space and have built in sound bars and better picture quality than ever with K and Dolby Vision features Better still you can now get K HDR models that can project up to a inch image for as little as That s around the same price and over double the size of a decent inch TV giving you something close to true movie theater immersion with a home theater projector There are a lot of different types of projectors though ranging from ultra short throw to portable to long throw There are also a lot of terms to understand like lens shift LCD vs DLP laser vs lamp illumination and more This guide will help you understand all that so that you can purchase the best projector for your needs within your budget The technologyHere are the basics Projectors generally use two types of technology LCD and DLP They re fundamentally different systems with their own advantages and drawbacks The rise of ultra short throw projectors and brighter long throw models meanwhile has been powered by falling prices in laser illumination technology Lasers are a far better solution than lamps because they re brighter and last far longer ーup to hours instead of That s essentially a lifetime of use about years Most projector manufacturers now use DLPs or digital light processing units manufactured nearly exclusively by Texas Instruments TI The heart of the tech is an optical semiconductor called a digital micromirror device DMD that contains millions of aluminum mirrors Those tilt either toward the light source on or away from it off at up to times per second Budget projectors like BenQ s HTi use TI s inch DMD while higher end models like the Samsung Premium LSPT use the inch chip Both use mirrors that tilt by and degrees for white and black but TI recently unveiled a new inch K capable DMD with degrees of tilt which should enhance both brightness and contrast DLP projector makers include LG Optoma LG BenQ and Panasonic The benefits of the tech are portability high contrast less fringing and cheaper projectors especially K and ultra short throw models The biggest drawback is the rainbow effect or bright red blue green artifacts that affect some viewers more than others LCD tech meanwhile uses a prism to split a light source into red green and blue beams Those then pass through LCD displays containing the image and converge via another prism before passing through the projector s lens Epson is the primary user of LCD tech along with Sony Sanyo and others LCD projectors tend to be sharper more efficient and more color accurate but have lower contrast ratios and can experience image degradation over time In general they re also more expensive What to look for in a projectorUltra short throwSince the last time we updated our guide ultra short throw projectors have become the hot new category offering several benefits You can mount them close to the wall like a TV with no need to run wires through the walls and ceiling but still get an immersive image as large as inches ーsomething that s impossible with a TV unless you re very rich They use brighter lasers that never need to be replaced ーand because laser light is collimated focusing is eliminated They re also physically less awkward to install than a ceiling mounted projector though that doesn t mean installation is super easy To get the perfect screen fit and alignment you must place them an exact height and distance from your wall or screen This can be quite a pain as I ve discovered You also need a perfectly flat wall or projector screen because ultra short throw projectors beam up at an acute angle so any imperfections will show as shadows For that reason you can t use a roll down screen because they have slight ripples For the best results particularly with a lot of ambient light you should use an ambient light rejecting ALR screen Those have small ridges that reflect light from below back to your eyes but absorb any light ie ambient light that comes from above For one of those you ll need to budget at least and way up Some projectors including models from Epson and HiSense come with ALR screens Elite Starling Brightness and contrastHome theater projectors generally range in brightness between to lumens but you ll need to take those figures with a grain of salt Some models might actually hit lumens or more but cranking the lamp to that level will hurt the image quality and lifespan of your bulb Also some manufacturers tend to exaggerate maximum brightness As a point of reference many K flat panel TVs nowadays can hit nits of brightness but the brightest consumer projectors only display between and nits from the screen That s not as big a deal as it might seem because projector images are much larger and meant to be used in dark rooms where your eyes will automatically adjust to the light and “brighten the image Contrast is also substantially different on home theater projectors Unlike OLED TVs projectors don t allow for zero black levels because of ambient light reflections and other reasons You also can t have local dimming zones found on LED TVs for true blacks Some projectors do have a dynamic iris to improve the contrast scene by scene but those can often produce a “pumping effect with the image dimming or brightening in mid scene Mounting and fan noiseA big advantage of regular long throw projectors is that you can mount the projector and screen on the ceiling using zero space in your room If you plan to do that don t forget to budget for a mounting bracket and any necessary long cables including extra power for Google s finicky Chromecast Also keep in mind that it s easier to mount a lightweight home theater projector and DLP models are usually lighter than those with LCD tech Some projectors are noisier than others and usually the more you spend the less noise you get Many of the new K DLP projectors when operating in K mode are particularly noisy There s one other cool thing if you have a portable projector or even one that is relatively easy to take down and put up you can take it outside for magical night screenings under the stars HDR and resolutionAs related to projectors these things could each take up an entire article In fact they have ーfor a deeper dive take a look at Projector Central s excellent takes on HDR and resolution On the resolution front only expensive projectors have native K resolution indeed most movie theaters still use K projectors for various reasons However there are many relatively inexpensive DLP projectors that use pixel shifting to attain K resolution That system emits each pixel four times while moving it to the correct position for a K image all in less than th of a second As such it puts as many pixels on the screen in the same amount of time as a K native projector ーand visually it performs nearly as well On the other hand Epson s LCD “K enhanced projectors also have p native resolution but the image is just shifted twice not four times So those projectors are not K natively or otherwise but do produce double the pixel count of a p projector If you really want a K native projector you ll have to pay two of the cheapest ones are Sony s VPL VWES and JVC s DLA NX HDR is a very different animal on projectors compared to TVs As mentioned projectors can t produce anywhere close to the amount of light required nits to qualify as true HDR Rather they use a technique called tone mapping to fit the entire HDR gamut into a lower brightness range For that reason among others almost all projectors only support HDR Only one uses Dolby Vision the Xiaomi Laser Cinema only available officially in China and just a couple of models work with Samsung s HDR ーand those are Samsung s own Premiere K models However most support a wider bit color gamut that allows for superior color reproduction Samsung OpticsIf you re mounting a short or long throw projector between five and feet you might need to consider the zoom range and whether the projector has a lens shift option A decent zoom range will make it easier to mount the projector where you want with the screen size that you want Lens shift meanwhile is used if the projector is mounted higher or lower relative to the screen than recommended by the manufacturer or any horizontal distance off center That creates a trapezoidal shaped image but by dialing in some lens shift you can optically square it up Otherwise you might have to use a keystone correction which digitally stretches or shrinks part of the image resulting in noticeable distortion or pixel artifacts Digital correction might not work in gaming modes either for some projector models GamingIf you re interested in a gaming projector you ll want to look up the refresh rate and input lag figures Some new projectors from Viewsonic Optoma and others offer up to Hz p refresh rates and input lag settings down to or milliseconds However some projectors designed more for home entertainment have very poor input lag and refresh rates at just Hz Portable projectorsFinally portable projectors have become popular enough to merit discussion this year They re relatively cheap compact and portable and can run on batteries making them ideal for entertainment outside or while camping These outdoor projectors are not nearly as bright as others of course but are more designed for a fun night of entertainment under the stars Engadget picksAs with previous updates I m dividing projectors into ultra short throw and long throw categories As mentioned ultra short throw models have rapidly established themselves in the market due to the extra performance and convenience and all manufacturers sell at least a couple of models Within the ultra short throw category We ll compare two price categories under and with three projectors each In the long throw category we re again looking at projectors under and with three products in each range Finally we ll take a look at the best portable projectors Best ultra short throw projectors under LG CineBeam HUQLG s nice looking HUQ is the new king of ultra short throw UST projectors due to the picture quality tech on offer and reasonable price With a hour laser light source it delivers ANSI lumens along with accurate colors across percent of the DCI P gamut enough for most HDR content And speaking of that it supports both HDR and HLG along with frame by frame tone mapping Rival models offer similar specs but the HUQ trumps them in sound and technology The watt way stereo speakers have a great sound quality on their own but you can supplement them with Bluetooth speakers from LG and nearly any other brand to create surround sound The standout feature though is LG s webOS smart TV capabilities that give you Netflix Disney Amazon Prime and other apps all with full K HDR support and surround sound including eARC output for Dolby Atmos and lossless audio It also supports HDMI and better still full K x rather than just UHD Optoma CinemaX P Steve Dent Engadget Optoma s CinemaX P made our list last year but it s one of the best projectors now because the price has dropped considerably It delivers lumen brightness impressive contrast ratio and accurate colors with percent DCI P coverage It s not quite as sharp as the pricier projectors as it uses TI s inch rather than inch DLP tech though you ll still get a near K image The CinemaX P may also better match your decor as it comes in white rather than dark grey like the P The watt NuForce Dolby Digital soundbar is one of the best on any ultra short throw projector as well On the downside it does offer apps but they re not as good as you ll find on say Google s Chromecast Buy Optoma CinemaX P at Amzon BenQ ViBenQ s first UST laser projector is at the top end of the price scale at but it offers some impressive capabilities Light output is a bright ANSI lumens and it delivers a full percent DCI P coverage for as good an HDR experience as you can get on a projector You also get a Filmmaker Mode to see colors as the directors intended It s powered by Android TV so you get all the streaming services and apps you want along with apps games and more The downside is the lack of decent speakers as it only offers dual watt speakers with clear sound but limited bass Buy BenQ Vi at Amazon Epson EpiqVision Ultra LSWIf you re okay with p projection Epson s EpiqVision Ultra LSW is a very interesting option because of the design excellent sound built in Android TV and extreme ANSI lumen brightness That allows for a wide color gamut with no rainbow effect excellent connectivity and very good sound without the need to buy a soundbar or surround sound system Best of all it s priced at just making it one of the cheaper short throw projectors out there Buy EpiqVision Ultra LSW at Amazon Best ultra short throw projectors under Samsung Premium LSPTUltra short throw projectors are a hot enough entertainment category that Samsung decided to re enter the market with two models as part of its Lifestyle TV series The LSPT is the premium model and it certainly brings some premium specs With separate red green and blue lasers it covers percent of the full Rec color range percent of DCI P ーsomething we ve rarely if ever seen on any TV or even pro monitor It delivers a very bright lumens and a ANSI contrast ratio As it uses TI s higher resolution inch DLP chip with pixel shifting you get as close as you can to true K without investing in a native K projector Finally the LSPT is the first projector on the market rated for HDR ーSamsung s answer to Dolby Vision On top of all that the LSPT delivers watts of audio using Samsung s Acoustic Beam technology while offering Samsung s well regarded Tizen powered Smart TV platform Epson EpiqVision Ultra LS Epson If you need the brightest possible image Epson s LCD powered EpiqVision Ultra LS delivers It s rated at up to lumens making it one of the brightest ultra short throw projectors in any price range It also supports HDR modes in HDR and HLG and is sold with both inch and inch ALR screens making the price effectively lower The main drawback is that it only offers double the pixels of p rather than four times like competing DLP tech It also offers a relatively weak watt built in speaker system Buy EpiqVision Ultra LS at Amazon HiSense LGThis is HiSense s new flagship UST that uses a tricolor laser to achieve high brightness ANSI lumens and an incredible percent BT HDR coverage topping even Samsung s formidable LSPT It has a powerful W Dolby Atmos sound system and built in Android TV with Google Assistant and Alexa Best of all that price includes a inch ALR Daylight screen or for an extra you can get it with a inch ALR cinema screen Buy HiSense LG at Amazon Best projectors under Viewsonic PX KThere are very few K projectors available under and Viewsonic s PX K is one of the most recent For the money it offers impressive performance You get K HDR with lumens of brightness via TI s inch DLP chip More importantly for gamers you can get a p signal at up to Hz with a millisecond input lag time The drawbacks are a limited x optical zoom so you ll need to make sure it fits in your space BenQ HTA BenQ For around the BenQ HTA is still one of the best budget p projectors It delivers where it counts with the best contrast ANSI and color accuracy in its class and is reasonably bright as well with lumens in vivid mode On top of that it comes with a x zoom and vertical lens shift option for maximum installation flexibility The drawbacks include slightly excessive fan noise rainbow effect and red tinted D Buy BenQ HTA at Amazon Optoma HDXIf you re looking to spend a little less the Optoma HDX is your best option Using DLP tech it delivers p at up to lumens with excellent brightness color accuracy contrast and black levels You also get decent millisecond input lag for gaming The drawbacks are a single HDMI port x optical zoom and poor built in audio Buy Optoma HD X at Amazon Best projectors under BenQ HTiBenQ s K HTi is an update to last year s HT but with a huge addition Android TV With that you get multi platform wireless projection from Android and iOS devices via Chromecast or Airplay ーa huge plus compared to rival projectors As before it offers reference quality K color reproduction in both HDR and SDR that s a match for projectors costing triple the price Contrast is excellent thanks to the dynamic iris though brightness is limited to lumens It has a x zoom and vertical lens shift option plus a surprisingly good built in speaker The fan noise is still present but less than before If brightness is more important than picture quality take a look at BenQ s TKi instead It also comes with Android TV but delivers far more brightness lumens in exchange for less color accurate picture quality Optoma UHD Optoma For extra brightness and speed for gaming the answer is Optoma s all new K capable UHD It cranks the lumens up to and like the Viewsonic PX K offers Hz gaming at p with one of the lowest latency figures we ve seen yet in a projector at milliseconds Otherwise you can do K Hz gaming with milliseconds of lag which is very quick for K It s optimized more for gaming than entertainment unlike BenQ s HTi but it
