![]() LinkedList class can act as a list and queue both because it implements List and Deque interfaces. Memory overhead is a concern in LinkedList as LinkedList needs to store and maintain the location of next and previous node elements whereas in ArrayList at each index it holds just the actual element or object.īy default, ArrayList creates an empty list with initial capacity of 10 (when capacity not specified) while LinkedList creates an empty list with no initial capacity.ĪrrayList class can act as a list only because it i mplements List only. With over 260,000 students 50+ Java Collection and Generic Interview Questions Without wasting any more of your time, here is my list of 50+ Java interview questions on Collection and. LinkedList can be traversed in reverse direction by using descending Iterator while there is no API available for ArrayList to traverse in backward direction. Insertion of elements and removal operations are generally faster in LinkedList rather than ArrayList. Array List get (int index) operation performs in constant time o (1) while LinkedList get (int index) operation run time is o (n). ![]() In case of LinkedList it traverses through every node from start to end or end to start (closest takes priority) to retrieve the node at the specified index. Retrieval (get (int index)) and search operations are faster in ArrayList compared to LinkedList in terms of performance as ArrayList internally uses array data structure and leverages index based retrieval. 34 Java Collections Interview Questions 1) What is the Collection framework in Java 2) What are the main differences between array and collection 3).

![]() ![]() What if you could guarantee you’ll see cash for those invoices right away? With accounts receivable financing, you have the chance to get paid for your invoices right away-no need to wait. That’s why we offer invoice and accounts receivable financing. One of the most frustrating aspects of running a growing business is waiting for your invoices to be paid-especially when some customers don’t pay on time.Īnd delayed payments mean you don’t get to funnel that capital back into your business right away, tying up your working capital and creating a whole host of trouble.Īt Upwise, we see this problem all the time with small business owners. To determine the factor rate underwriting evaluates your business financial history and credit and the credit and payment history of the company’s customers. Other factors such as industry, market projections, quality of the invoice, company reputation, and time in business are taken into account as well. The factor is usually repaid once their customers pay their outstanding invoices and will charge a fee based on the amount of financing provided and the duration of repayment. Late paying customers can disrupt the day to operations of a business, which can be avoided by factoring in your receivables or money coming in from customers or work completed. The lender is known as a factor or factoring company and typically will lend up to 90% of the invoices being purchased. Invoice financing is a good tool for business owners to use when their clients are not paying their invoices on time. Most business owners have work that is paid on a net 30, 60, or 90 meaning that the invoice will be paid within 30, 60, or 90 days. Billing cycles are different per industry and no two businesses are alike. ![]() ![]() Update your Android project's AndroidManifest.xml to include a network security configuration file: Obtain and install the certificate file as for FOS 5, above.You will be asked to authenticate with your Amazon credentials and an onscreen notification will confirm success.

You can also review the complete list of Fire TV devices and their corresponding Fire OS versions. To determine the Fire OS version installed on your test device, go to Settings > My Fire TV > About > Fire TV and look at the "Software Version" details. ![]() On Fire OS 6, each app must explicitly specify which certificates it trusts by listing them in res/xml/network_security_config.xml. On Fire OS 5, simply installing the certificate on your device is sufficient, since all apps implicitly trust certificates installed at the device level. To take advantage of SSL Proxying in Charles Proxy, your app must trust the certificate authority (Charles CA) used to sign the substitute certificate that Charles Proxy generates. It uses this substitute certificate to establish a secure connection with your app, then securely connects to the remote site using the original server certificate it received, allowing you to view in plain text the communication between your app and the SSL web server. When your app attempts to communicate with a remote server, Charles Proxy intercepts the server certificate and dynamically generates and signs one of its own. Charles Proxy is a popular utility that offers this feature. Some proxies support SSL Proxying, allowing you to view network traffic even when it's encrypted. In this case, traffic is SSL-encrypted between source and destination, keeping it private-the data is inaccessible even to a proxy you configure yourself through the Network Proxy option. If your app works with sensitive information, it is likely that you rely on HTTPS connections to protect against eavesdropping and man-in-the-middle attacks. Working with HTTPS and Encrypted Data using Charles Proxy The proxy host and your Fire TV must be on the same network. The Network Proxy option allows you to specify the hostname and port of a proxy through which all network traffic will pass, allowing you to observe the data sent to or from your app. This includes requests initiated by your app and the responses it receives, as well as HTTP headers containing (among other things) cookies and caching information. If your app communicates with remote services or websites, it's often useful to inspect the HTTP or HTTPS traffic it generates.
![]() However, there's a flip side to this: Every program that renders yellow highlights in fire, does the same for overexposed skin, twists overexposed skies cyan, and red flowers magenta. ACDSee and ON1 probably take the yellow a bit too far. You can see Darktable v6, DxO PhotoLab, RawTherapee, Exposure, and Zoner leaning towards desaturation, while the others render yellow color twists of some form or another. So a balance has to be struck between merely desaturating highlights, and twisting them yellow. There's a difficult tradeoff to be made here: Fire highlights physically don't change hue much compared to the fire body, but we visibly expect "hotter" fire to twist yellow.

I tried to inject some objectivity by limiting my edits to the most obvious sliders wherever possible, especially in the programs I know better. ![]() Of course I am no expert in any of them except Darktable and Capture One, so my results are probably flawed. In order to put them through their paces, I took a random smattering of images from the last few years that I found difficult to work with for one reason or another, and checked how each of the programs dealt with them. I also installed Luminar Neo (€120 or €80/a) and Radiant Photo (€140) but I disliked them so immediately and viscerally that I didn't include them in the comparison below. Or maybe I just wanted a justification for buying DxO PhotoLab, because people on the internet speak so well of it □.įor the following comparison I downloaded trial versions of ACDSee Photo Studio Ultimate 2023 (€155), Capture One 22 (€350 or €220/a), Darktable 4.0 (free), DxO Photolab 6 (€220 + €140 for FilmPack 6 + €99 for ViewPoint), Adobe Lightroom Classic 11.5 (€142/a), ON1 Photo Raw 2023 (€126), RawTherapee 5.8 (free), Silkypix Developer Studio Pro 11 (€155), Exposure X7 (€165), and Zoner Photo Studio X Fall 2022 (€60/a).

To solve the problem an auxiliary, usually weaker, winding is added to the motor and it is offset from the main coil by, say, 30°. The single phase induction motor is similar. Induction motor with square rotor because there is no circle tool in the schematic editor. Simulate this circuit – Schematic created using CircuitLab It's OK once you get it going but trying to get the start direction right and starting from top or bottom dead-centre is awkward. Trying to start a single phase motor with only one winding would be a bit like trying to start a bike with only one pedal. Lastly, is the capacitor placed between (downstream from) the start windings and neutral, or could it be wired between incoming voltage and the windings? When voltage on the hot leg oscillates down to zero, does the capacitor discharge back toward the starter windings, or does current flow through the capacitor to the neutral leg?īasically I don't understand where the capacitor's charge goes when the hot leg is hot and when it is not. But I don't know how the voltage and current behave.ĭoes voltage energize the hot leg, flow through the start windings and then charge the capacitor? So, a capacitor is wired in series with the start windings which I kind of understand. Problem there I guess is that both windings would be in phase and thus no spin created for the rotor. Without a capacitor, the same thing would happen to the start windings. Wiring diagrams seem to suggest that voltage energizes the hot leg of the circuit and current flows through the run windings and then returns via the neutral leg. I don't understand the direction of current flow when a capacitor is wired in series with the start windings in, say, a fridge or other AC motor running at/under 120V AC. ![]() ![]() ![]() It is not known how many people may have died as a result of the flooding. Kyiv said several months ago the dam had been mined by Russian forces who captured it early in their invasion, and has suggested Moscow blew it up to try to prevent Ukrainian forces crossing the Dnipro river in their counteroffensive. Putin, without providing evidence, has accused Ukraine of destroying the Russian-controlled dam at the suggestion of its Western allies. The Kremlin said Putin had no plans to visit the region but was monitoring the situation. "Drinking water remains the most pressing need," it said. Office for the Coordination of Humanitarian Affairs said aid agencies had delivered bottles of drinking water, water purification tablets, hygiene kits and jerrycans. Ukrainian President Volodymyr Zelenskiy, who has appealed for a "clear and rapid" international effort to help flood victims, held emergency talks with officials in Kherson, one of five Ukrainian regions which Moscow claims to have annexed but only partially controls. ![]() Ukraine said the floods would leave hundreds of thousands of people without access to drinking water, swamp tens of thousands of hectares of agricultural land and turn at least 500,000 hectares deprived of irrigation into "deserts". "The latest information is that there was a lot of water in the street, as high as a person," he said. One man, Sergei, told Reuters the last time he spoke with his 83-year-old father-in-law in the Oleshky region was several days before the dam collapse. The coordinator of a volunteer group on the Telegram messaging app said the appeals were getting more urgent because people were running out of drinking water. Reuters could not independently verify the battlefield reports.įriends and family of stranded residents posted appeals online with names, photos and GPS locations of residents.

However, this is subject to how the exercise was performed, which weights were used, and the positioning of the subject.Īs added fuel to the fire, bodybuilding champions such as Ronnie Coleman and Arnold Schwarzenegger have repeatedly shown that they perform dumbbell pullover exercises in their chest and back routines, so it is clear that both muscle groups are engaged during this exercise. Some studies have shown that during the dumbbell pullover exercise, the chest is worked out more than the lats, and will activate the chest muscles more. These muscles are the serratus anterior, the triceps, and the front and rear deltoid muscles found in the shoulders. In addition, other muscles will be worked out during this routine, but not to the same extent. This is why this exercise is very popular, as you can build strength and muscle in the back and the chest at the same time! However, generally speaking, and depending on how this exercise is done, the main emphasis will be placed on the lats, or latissimus dorsi, and the chest, or the pectoralis major. This will then require different muscles to engage, in order to perform the dumbbell pullover successfully. What we mean by this, is that different body positioning, techniques, arm positions and various different ranges of motions can shift the load, and the weight during this exercise. This comes as no surprise, as many people can perform this exercise in various ways in order to work out different muscles simultaneously. When it comes to the dumbbell pullover, there is a lot of debate as to which is the target muscle that is mainly worked in doing this exercise. If you implement some variations to your movements and technique, then you can also simultaneously work your core muscles, and engage the muscles in the back of your upper arms, such as the triceps. A classic dumbbell pullover is widely used as a resistance based exercise, which can strengthen the muscles in your chest (pectoralis major), along with the larger wing shaped muscles found in the back (latissimus dorsi). The good thing about dumbbell pullovers is that you can work multiple muscles at once. But first, let’s take a look at which muscles the dumbbell pullover works. This is why, in this guide, we will show you exactly how to do a dumbbell pullover, with a step by step guide, and a video tutorial. This only works as long as you are performing the dumbbell pullover correctly, and engaging all of the right muscles, with the accurate movement. This, in turn, increases the flexibility of your upper body and chest muscles, as you are participating in a full range of motion during the pullover movement. That being said, the dumbbell pullover is also utilized by sports physiologists as it is a postural exercise that takes place lying down, which can help lengthen and stabilize the spine. The main purpose of this exercise is to work the back and chest muscles, in order to strengthen them, and help you gain muscle mass. If it’s good enough for Arnold Schwarzenegger, then it’s good enough for us!

Most amethysts are found in volcanic rocks with the largest deposits in Brazil and Uruguay. Sahasrara is meant to control spirituality, consciousness, and enlightenment. ![]() Sahasrara is the centre of enlightenment and is the most spiritual of all the chakras. The final chakra is our purple chakra, which is called Sahasrara, meaning “'thousand-petaled.” This chakra is found at the crown of your head and is associated with the colours purple and white. The Ametrine Queen Ring, Regal Collection Ametrine is one of my favourite gemstones and one of the first stones I used in my first ever collection. Amethyst can also be reddish, and purple and when both amethyst and citrine are discovered in a quartz gemstone, you get Ametrine, which comes in beautiful bands of yellow and purple. We often think of amethyst as a dark purple gem only, but amethysts actually occur in a range of colours from light purple to a rich, dark, nearly opaque purple. You are an organic being which means your energy and your frequency will attune and be raised to match the energy and the frequency of the Amethyst crystal. Sit with Amethyst and adjust your frequency to hers. By directing love to the amethyst the energy is increased and returned to the wearer and will clear away unproductive and unkind vibrations. She helps clear negative, intoxicating energies and behavioural patterns. Amethyst is a gem with deep healing and cleansing powers and is historically known to help free you from addictions to substances and people. known as a wonderful gem for meditation, she opens and activates your crown chakra acting as an excellent conductor to help you create peace, calm and tranquillity within. ![]() The world needs amethyst.īelow are my favourite Amethyst earrings from the Opulence collectionĪmethyst balances the physical, mental and emotional bodies.

A stone that represents the process of a complete metamorphosis, she is the butterfly of the gem world. She is a wonderful facilitator to help you transform your lower energies into higher frequencies of both the spiritual and ethereal levels. However, when it comes to how we can use these stones spiritually and energetically, wow - then this really does change the game when it comes to the 'value' of our beloved Amethyst.Īmethyst gemstones were once worn on the breast plates of High Priests and are known as a 'stone of spirituality and contentment'. All stones are precious and depending on how easy they are to source can greatly affect their market value. This is true, they are but mainly because historically, these stones were named as 'precious' purely because they were harder to find at the time. We tend to look at these four precious gemstones as valuable: Diamond, Ruby, Emerald and Sapphire. I have always felt that amethyst is an under looked stone of 'value' in the gem world. When I spoke to my gemologist friend Jo Williams, she said it is because Amethyst, literally throws out energy from the points of its shards. I always feel my rocks but this experience was exponential. I spent a lot of time in the Tucson gem show, resonating around 6 foot tall pieces of Amethyst. But what about the power of Amethyst & its spiritual meaning? ![]() ![]() Frank Petingell looks more comfortable than Joseph Cotton, his performance is more even (though Cotton was hardly bad), the character is better written and he is more believable as a police officer (where Cotton's performance particularly fell down on). Diana Wynward demonstrates Bella's vulnerability incredibly movingly with no histrionics and she's hardly dull either (though the character has more range and depth to her in the 1944 version). Anton Walbrook, while not as subtle as Charles Boyer, is terrifying and a huge part as to why the film is as atmospheric as it is. Performances are great here and hardly inferior to those in the later film, despite being less familiar. Tighter-paced and more theatrical somewhat, the story never creaks and is leaden with tension and suspense with nothing obvious that came over as unnecessary or clumsy. The script is thought-provoking and tense, everything feels relevant to what's going on and nothing seemed padded. It's intelligently and suspensefully directed by then-famous-and-well-regarded, now-almost-forgotten (undeservedly) Thorald Dickinson. It's shot beautifully and menacingly, is hauntingly lit and has sets that are picturesque yet give off a great amount of dread while over-stating it. However, while not as glossy as the later film 'Gaslight' (1940) regardless is incredibly well-made. The secondary characters could have been better fleshed out, and while Richard Adinsell's music score is suitably ominous Bonislau Kaper's score for the later version has more atmosphere, subtlety and tension. Like the 1944 film (the only real drawback to that film was the uneven performance of Joseph Cotton), there is very little wrong here. To me, both 'Gaslight' films are great in their own way, and this reviewer ranks them equally, yet with one or two things in things that are done better in the other. ![]() ![]() It is inevitable that this 1940 film and the 1944 "remake" with Charles Boyer and Ingrid Bergman are going to be compared, and people will have different opinions as to which is the better version. ![]() |
