If the TRIM function is automatically enabled, then the SSD will wipe free space automatically. Here, you will see two results! If you see disabledeletenotify = 0, then it means that the TRIM function is enabled, and if you see disabledeletenotify = 1, then it means that the TRIM function is disabled.Īs you have learned "how to check the status of TRIM function," it's now time for you to know-how solutions under each of these situations work! Solution 1: If TRIM Function is Enabled Step 3: Now, run the fsutil behavior query disabledeletenotify command in the "Command Prompt" window. Step 2: Right-click on the "Command Prompt" shortcut and chose the "Run as Administrator" option. Step 1: Go to "Start" menu on your PC and search for "Command Prompt". Though Windows 7 and above are set to enable the TRIM function on SSDs automatically but if you want to double-check, then you can easily do it by following the steps below: In order to know how to check the status of the TRIM function, the below-mentioned steps will help you out! Tip: How to Check If TRIM Function is Enabled or Disabled? Now, if we talk about the process to wipe free space SSD, then there are two possible solutions that entirely depend upon whether the TRIM function is enabled or disabled.

The Batman: reading another card left by Riddler Im mad about you. Like most of the recent films in the Batman franchise, this one is also pretty dark. Whether you’re a superhero super fan or you’re just curious about the new movie, these quotes from The Batman make the perfect Instagram captions. 2022’s The Batman is filled with iconic imagery and a boatload of A-list actors that deliver some pretty epic lines. One that held a much more personal meaning to Clark.After a long wait, DC’s newest superhero thriller finally arrived on the big screen on Friday, March 4, and already, fans can’t stop raving about it. His thoughts turned to another example of the peak of human achievement, of what one man with drive, desire and dedication could accomplish without the benefit of superpowers or metagene enhancement. This set were Sherpa prayer flags, each displaying a symbol, not of a distant god or mythological beast, but denoting some aspect of the enlightened human mind: compassion, perfect action, fearlessness. And today, it represented something else as well: man’s ability to conquer the harsh reality of nature… a point in stark contrast to the previous night’s activities. 1 day ago &0183 &32 Much like Riddler himself, reviewing a book as slow as this requires seeing the forest for the trees, criticizing what you can with the space that you have. To Clark, each of these markers indicated the pinnacle of human achievement, the fulfilled promise of the best the human race had to offer. Each one was different and each one seemed to reflect the personality of the party it represented: small flags and banners with the hand-written names of climbers past, a used oxygen canister, a spare glove, even a small metal lunchbox with (Clark noted with a small smile) a picture of Superman on the cover. It was tradition for every expedition to the top of Everest to leave something behind-a small token or marker indicating their successful climb to the famous peak. He glanced around the summit, noting the other reason why he enjoyed coming up here. “When it came to "getting away from it all," there really weren’t many places quite like the top of the tallest mountain in the world. 5/2/2023 0 Comments 4d movie theater orlandoI left the theater and my tailbone was it so much pain. Every time I would finally find a spot that was sort of comfortable, the seat would shift downward almost knocking me out of the seat. Which caused me to spend most of the movie leaning on my friend so that I didn’t get to close to the stranger sitting next to me. They were kind of small and were uncomfortably close to the seat next to you. Imagine having to sit through Shrek 4D at Universal for 2 hours. I didn’t experience much in the way of smells during “ Fast & Furious Presents: Hobbs & Shaw,” save for a blast of air freshener during a roller coaster short that played before the movie, but I can’t complain about not spending 2 hours and 16 minutes smelling exhaust fumes and singed leather, either.The 4DX theater is probably one of the worst movie experiences I’ve ever had. I walked out feeling like I’d just thrown my neck out while riding a four-wheeler down a mogul-filled ski slope, but I’d lie if I said I didn’t enjoy it. But I also wouldn’t recommend it to anyone who has ever, say, thrown their back out by opening a cupboard door incorrectly, because the hydraulic chairs do jostle without warning sometimes. And it’s fun: Suddenly, the action scenes that I usually use as an excuse to refill my popcorn felt a lot more engaging, literally. What I expected to feel like an indoor rollercoaster felt more like riding an ATV through a Regal Cinema. The movement wasn’t enough to make me feel ill, but it was a pretty impressive amount of jostling. As someone who gets occasionally carsick - and ate a giant breakfast before Thursday’s screening - let’s just say that throwing up into my popcorn bag was a bit of a concern. I can’t recall what was showing - something about sharks or space or dinosaurs - but I do remember that my entire family became quite ill about halfway in, and closing our eyes didn’t help. A few years ago, while on a Disney trip with my family, we saw Disney’s version of a 4D movie in what was much more like a ride than a film screening. It’s a combination of vibration and air-blowers around your calves that does make for a, let’s say, unique experience.Īnd then there’s the movement. Your legs will also experience what CJ 4DPLEX calls “ticklers,” which is not, in fact, something you would buy at Fascinations. It’s not enough rain to soak you, but it is enough for glasses-wearers to require a quick squeegee. When it storms in the movie, flashing lights simulate lightning, and rain trickles down from above (you can turn this feature off, by the way, via a button on your armrest). You’ll feel a lot more than just car wrecks: Your seat vibrates with heavy footsteps and even lightly “punches” you in the back during fight scenes. Because, truth be told, “Fast & Furious” may be the perfect franchise for 4DX, what with its myriad action scenes, car crashes and even the mist spraying around your head when Jason Statham dramatically breaks a bottle of Champagne. Now, I’m not trying to discourage anyone from feeling the sensation of a high-speed car chase or, say, a helicopter crash at the base of a Samoan waterfall, but you should have all the information going in. But your post-movie chiropractor visit might set you back a little more. The tech simulates lightning, thunder, rain, fog, even explosions and the low rumble of a passing car’s engine.Īs you can imagine, seeing a movie in 4DX doesn’t come cheap: Tickets for a Friday night screening of “Fast & Furious Presents: Hobbs & Shaw” in 2D 4DX (which means it’s not in 3D, but you’ll still get the 4DX effects) will set you back $20.24, compared to classic 2D, which costs $12.74 per ticket if you’re buying online. The technology comes from CJ 4DPLEX, a Korean company that hires producers to perfectly sync chair movement, utilize smoke machines, vibrations and water vapor with Hollywood blockbusters like “The Lion King” and the latest in the “Fast & Furious” franchise. There are now 25 4DX theaters in the United States, with plans for more. The “immersive theater format” uses hydraulic seats, smells and simulated weather to “create a multisensory experience, immersing movie fans in an unforgettable cinematic event,” according to a press release. Last month, Regal UA Denver Pavilions quietly opened a new state-of-the-art 4DX movie theater. I could make up a reason - while rescuing a fallen hiker on a fourteener, perhaps, or getting into a fistfight with a City Park goose - but the reality is so much more embarrassing: It happened at a press screening Thursday of “Fast & Furious Presents: Hobbs & Shaw” in 4DX. The first person to ask me how I threw my neck out is going to get what Dwayne “The Rock” Johnson refers to as “an ice-cold can of whoop-ass.” Thursday, March 9th 2023 Home Page Close Menu 5/2/2023 0 Comments Fast food places near meThey also accept all major credit and debit cards, including Apple Pay, PayPal, and Google Pay.

5/2/2023 0 Comments Jquery showhide on clickYou can see an animating image is just like another element that I used in above examples. As you click on show/hide link, the image will be disappeared if visible and shown if hidden. In the following example, an image tag is created with its ID. Remember that, when you specify duration parameter the jQuery toggle method becomes an animation method. Unlike above example where I used easing values other than swing and linear, you do not need to include jQuery UI library for swing and linear effect. As I did not specify the easing value, it will use default i.e. Upon clicking the show/hide Menu link, the div containing vertical menu will disappear with duration of three seconds. Click on the link below to see live demo and code: The menu’s CSS and HTML is also given.Īlso, I used a link rather a button in this example to show / hide or toggle div element. The menu items are created inside a parent div element by using unordered list tag, ul. In this example, I have created a vertical menu with general menu items. The list of available easing values can be seen in the official website: An example of show/hide menu As animation is completed an alert will be shown which is placed inside the callback function. Following code is used in the jQuery part: The duration is set to 1500 ms, the easing value used: easeOutQuint (you must include jquery UI library for that to work) and finally a callback function. When you click on the “show/hide” circle button, the toggle jQuery method will be called with three options. In this example, I will use the jQuery library to use other easing option.Īs you can see, I have created a circle with some text (basically for jQuery show / hide div example). While if jQuery UI library is used, other easing options may also be specified. If you are using the jQuery library only, you may specify swing (which is default) or “linear” options. You may perform some action at the end of animation or show some descriptive message to your visitors. The callback function will execute as the animation is done. In the following example, I will use duration as well as the callback function. Whereas, the value provided as fast means 200 milliseconds and slow means 600 MS. The more the value of milliseconds the slower will be animation. “fast” or “slow” or provide time in milliseconds. In duration parameter, you can use strings e.g. When the duration is used in toggle method, this method becomes an animation method. The method uses are duration, ease and call back function in the toggle method. In the following example, different options available with toggle jQuery method are used. In this example, I simply used toggle method without using any parameters or options like duration, easing effect or a callback function that I will use in coming examples.Ī toggle example with ease and callback function options In the click event of the button, I placed jQuery toggle method which is attached to a div element with id: toggle_tst. As you click on the button “Show/Hide” if the div element was visible it will be hidden and vice versa. In this example, I will use toggle jQuery method to show or hide a div element. Click on the given links or demo images to see it online. Where, a selector can be div, paragraph, a class, ID, HTMl table, lists etc.įollowing are a few examples of using the jQuery toggle method with codes where I will use different parameters of toggle method as well. This is how you may use the toggle method: If only a single target is required, for example, only allowing to hide a visible element or showing a hidden element then you should use $.hide and $.show methods, respectively. in your web pages by giving a switchable option. Use toggle method if you need to allow users show or hide any elements like div, menu, paragraphs etc. The toggle method of jQuery will hide specified visible element and display the hidden elements. Meanwhile, Amazon’s Kindle e-reader will collect data such as what you read, when, how fast you read, what you’ve highlighted and book genres. You also have the option to turn the feature off in the Amazon Photos app or on the website. But it makes no such commitment about other types of photo data, such as geolocation tags, device information or attributes of people and objects featured in images.”Īmazon Photos does not sell customer information and data to third parties or use content for ad targeting, an Amazon spokesperson says, insisting the feature is for ease of use. “Amazon promises not to share facial recognition data with third parties. If you use Amazon to store your photos, a facial recognition feature is enabled by default, she says. “From this information, Amazon can work out where you work, where you live, how you spend your leisure time and who your family and friends are,” says Rowenna Fielding, director of data protection consultancy Miss IG Geek.Īt the same time, Prime Video and Fire TV information about what you watch and listen to can reveal your politics, religion, culture and economic status, says Fielding. For example, if you just use its online retail site via the app or website, Amazon will collect data such as purchase dates and payment and delivery information. Some of the data is used for “personalisation” – big tech speak for using your data to improve your online experience – but it can reveal a lot about you. How often you look up words on the Kindle e-reader might indicate how literate you are in a certain language Meanwhile, when you use its website, cookie trackers are used to “enhance your shopping experience” and improve its services, Amazon says. It knows your orders, content you watch on Prime, your contacts if you upload them and communications with it via email. This covers three areas: information you give Amazon, data it collects automatically and information from other sources such as delivery data from carriers.Īmazon can collect your name, address, searches and recordings when you speak to the Alexa voice assistant. But, according to Amazon’s privacy policy, the tech giant still collects a large amount of information. Strict EU regulation in the General Data Protection Regulation (GDPR) and UK equivalent the Data Protection Act limit the ways personal data can be used in Europe compared with the US. So, what data does Amazon collect and share and what can you do to stop it? The data Amazon collects, according to its privacy policy And a recent Wired investigation showed concerning privacy and security failings at the tech giant. Last year, Amazon was hit with a $886.6m (£636m) fine for processing personal data in violation of EU data protection rules, which it is appealing against. Like its data-grabbing counterparts Google and Facebook, Amazon’s practices have come under the scrutiny of regulators. Those who have requested their data from Amazon are astonished by the vast amounts of information they are sent, including audio files from each time they speak to the company’s voice assistant, Alexa. Not everyone is happy about this level of surveillance. The firm’s software is so accomplished at prediction that third parties can hire its algorithms as a service called Amazon Forecast. The more Amazon and services you use – whether it’s the shopping app, the Kindle e-reader, the Ring doorbell, Echo smart speaker or the Prime streaming service – the more their algorithms can infer what kind of person you are and what you are most likely to buy next. The 200 million users who are Amazon Prime members are not only the corporation’s most valuable customers but also their richest source of user data. Continuous analysis of customer data determines, among other things, prices, suggested purchases and what profitable own-label products Amazon chooses to produce. F rom selling books out of Jeff Bezos’s garage to a global conglomerate with a yearly revenue topping $400bn (£290bn), much of the monstrous growth of Amazon has been fuelled by its customers’ data. 5/1/2023 0 Comments Atomic clocksOne issue the road map does not address, Ludlow says, is how to choose which atomic transition-and hence type of clock-will ultimately come to define the second. Ludlow says the measurements are not far off the desired accuracy, and that once they've finished they can compare their results with labs in Europe or Asia. The NIST scientists and colleagues at JILA, a research institute down the road in Boulder, are doing just that, comparing the ytterbium clocks to others that rely on strontium atoms and aluminum ions. Another check involves comparing the ticking of different types of atomic clocks. The BIPM road map calls for a number of cross-checks, including reaching the required accuracy with clocks in different labs. Jérôme Lodewyck, a physicist working on strontium lattice clocks at the Paris Observatory's Time-Space Reference Systems lab, says the NIST result "is probably correct," but that when it comes to changing the second, "probably correct is not good enough." He notes that something unexpected-perhaps a stray electric field-could throw off two clocks in the same lab by the same amount, making the drift undetectable. "It would be the first time that two clocks of the same species have been shown to agree at that level," Ludlow says.īeing a cautious bunch, metrologists will not accept the NIST result at face value. The researchers found that the two clocks ticked at the same rate to within 1.4 parts in 10 18-just over 100 times better than the top cesium devices. The NIST team operated two optical clocks, using several lasers to cool and trap a few thousand ytterbium atoms in an "optical lattice" and then excite a particular energy transition in those atoms. And in unpublished work, Andrew Ludlow and colleagues at NIST appear to have reached the accuracy stipulated by BIPM's first milestone. On 14 February it published a paper in its journal, Metrologia, setting out five milestones that should be met before the second can be redefined based on visible light. Improvements in laser technology led BIPM a few years ago to begin reviewing the accuracy of optical clocks. However, the lasers needed to cool atoms and provide a stable reference at these frequencies are a challenge to build. The frequency of visible light is about 100,000 times higher than that of microwaves, promising even more precision. Today, the best cesium clocks have accuracies of 1.6 parts in 10 16. In 1967, the second was defined as 9,192,631,770 cycles of a beam tuned to the cesium standard. Current atomic clocks depend on the oscillations of a microwave beam at the precise frequency needed to excite atoms of cesium-133 to a higher energy level. A grandfather clock relies on the regular swings of a pendulum, and the original definition of the second was based on the length of a day as fixed by Earth's spin. Already, physicists at the National Institute of Standards and Technology (NIST) Boulder Laboratories in Colorado appear to have satisfied one of the road map's key requirements-a 100-fold improvement in accuracy over the best microwave clocks-using a pair of optical clocks.Ĭlocks mark time by tracking a periodic action. In a paper out last month, a group of experts set up by the International Bureau of Weights and Measures (BIPM) in Sèvres, France, lays out a road map for the steps needed to redefine the unit of time-the metric second-in terms of optical radiation. So the push is on to replace current clocks, which are tuned to a specific microwave frequency, with even better clocks that exploit higher-frequency visible light. A more precise time standard might improve the navigation of spacecraft and help experimenters look for variations in fundamental constants that would signal new physics. The atomic clocks that mark official time lose the equivalent of just 1 second every 200 million years. 5/1/2023 0 Comments Ceiling led panel light 2x2Cheap plastic heat sinks don’t work as effectively as metal heat sinks and can reduce the life expectancy of the LEDs in the panel.This helps to prevent LED panels from overheating as a conductive metal heat sink takes away excess heat to keep the panel cool.A poor quality heat sink will mean not enough heat is dissipated from the LED chips which can cause the chips to burnout.Issues with the reflector plate can cause glare. This reflects light back into the light guide plate.Overtime, plastic diffusers can discolour at the edges and turn yellow, reducing the quality of light produced by the LED panel.This ensures the light coming from the LEDs is evenly distributed and helps to reduce glare.A low quality diffuser, made from acrylic or PMMA rather than polycarbonate, won’t distribute light as evenly.This points the light coming from the LEDs towards the diffuser.If it’s not fitted correctly then this can impact on the amount of light and the angle of the light reaching the diffuser.If low quality LED chips are used in a panel this can produce a ‘blue’ hue which can make a room look cold.Depending on the type of panel, they are mounted to the back or sides of the panel.Low quality chips can cause a number of problems including the panel becoming dim or the colour quality being compromised. These chips are mounted to a circuit board and are what produce the light.Usually made of aluminium, the frame contains the light within the panel.If the frame is too light or is made of a material other than aluminium (cheap LED panels often feature a plastic frame), then this could create excess heat and increase the risk of burn out from overheating. |
