Imagine if you did this:\n\n```\nlong a = ...;\nint b = ...;\n\nlong c = a % b + Integer.MAX_VALUE;\n\n```\n\nIf Java automatically down-casted `a % b` to an `int`, then the above code would cause an `int` overflow rather than setting `c` to a perfectly reasonable `long` value.\n\nThis is the same reason that performing operations with a `double` and an `int` will produce a `double`. It's much safer to up-cast the least-accurate value to a more accurate one. Then if the programmer knows more than the compiler and wants to down-cast, he can do it explicitly.\n\nUpdate\n------\n\nAlso, after thinking more about this, I'm guessing most CPU architectures don't have operations that combine 32-bit and 64-bit values. So the 32-bit value would need to be promoted to a 64-bit value just to use it as an argument to the CPU's mod operation, and the result of that operation would be a 64-bit value natively. A down-cast to an `int` would add an operation, which has performance implications. Combining that fact with the idea that you might actually want to keep a `long` value for other operations (as I mention above), it really wouldn't make sense to force the result into an `int` unless the developer explicitly wants it to be one."}}},{"rowIdx":11,"cells":{"qid":{"kind":"number","value":45507197,"string":"45,507,197"},"question":{"kind":"string","value":"This is about converting the enumeration values to a string array.

The exact distance between the cg and the Centre of pressure will depend on aircraft loading, configuration, thrust setting and drag. However, cg forward of the Centre of Pressure produces a nose-down pitching moment. The horizontal stabilizer, or tailplane, then provides a downward force to overcome this normal, nose-down, pitching moment.\nThe tailplane behaves as an ‘upside down’ wing and operates with negative Angle of Attack (AOA) as shown in Figure 1\n\n***Positive and Negative Angle of Attack***\n\n\n\nFigure 1 - Positive and Negative Angle of Attack\n\nIf the horizontal stabiliser becomes contaminated with ice, airflow separation from the surface can prevent it from providing sufficient downward force or negative lift to balance the aircraft and a nose-down pitch upset can occur.\n\nWhen compared to an aircraft's mainplane, the horizontal stabiliser normally has a thinner aerofoil with a sharper leading edge. Differences in the ice collection efficiency or catch rate between the two surfaces means ice accumulates faster on the horizontal stabiliser and may form before any ice is present on the aircraft's mainplane.\n\nTailplane stall can occur at relatively high speeds, well above the normal 1G stall speed of the mainplane. Typically, tailplane stall induced by icing is most likely to occur near the flap limit speed when the flaps are extended to the landing position, especially when extension is combined with a nose down pitching manoeuvre, airspeed change, power change or flight through turbulence. Aircraft stall warning systems provide warnings based on an uncontaminated mainplane stall so during a tailplane stall induced upset there will be NO artificial stall warning indications, such as a stick shaker, warning horn or the mainplane or flap buffeting normally associated with a mainplane stall.\n\n**Tailplane Stall Aerodynamics**\n\n1. The horizontal stabiliser, or tailplane, of an aircraft is an aerofoil that provides a downward force to overcome the aircraft's normal nose-down pitching moment. The further forward the Centre of Gravity is from the Center of Pressure, the greater the nose down moment and, thus, the greater the amount of down-force that must be generated by the tailplane. This, in turn, requires a greater negative tailplane angle of attack (AOA). angle of attack (AOA).\n[As shown in Figure 1, The tailplane is effectively an upside down aerofoil so an increase in negative tailplane AOA occurs with UP elevator movement or when the aircraft is pitching nose down.]\n2. Accumulation of ice on the tailplane will result in disruption of the normal airflow around that surface and will reduce the critical (or stalling) negative AOA of the horizontal stabiliser.\n3. Ice can accumulate on the tailplane before it begins to accumulate on the mainplane or other parts of the aircraft.\n4. Flaps extension usually moves the mainplane Centre of Pressure aft, lengthening the arm between the Centre of Pressure and the cg and increasing the mainplane nose down moment. More down force is required from the tailplane to counter this moment, necessitating a higher negative tailplane AOA.\n5. Flap extension, especially near the maximum extension speed, increases the negative tailplane AOA due to the increase in downwash, as shown in Figure 2\n6. Increasing the power setting on a propeller driven aircraft may, depending on aircraft configuration and flap settings, increase the downwash and negative tailplane AOA.\n7. When the critical negative AOA of the horizontal stabiliser is exceeded causing it to stall.\n8. Tailplane stall drastically reduces the downward force it produces, creating a rapid aircraft nose-down pitching moment.\n\n**Effect of mainplane flap on downwash**\n\n\n\nFigure 2 - Effect of mainplane flap on downwash\n\nOn aircraft with reversible (unpowered) elevator, tailplane airflow changes caused by ice accretion may lead to an aerodynamic overbalance driving the elevator trailing edge down and pitching the aircraft nose down. This can occur separately from or in combination with the nose down pitching moment caused by tailplane stall. The yoke may be snatched forward out of the pilot’s hands and the control force required for the pilot to return the elevator to neutral or to a nose-up deflection can be significant and potentially greater than the pilot can exert.\n\n**now match with your recovery actions**\n\n1. You have no doubt with your 1st point.\n2. The second point: You have to resist the nose down elevator movement. Once the tailplane is already stalled then you have to assume the elevator has already gone in down position to make your ac nose down. So you have to apply nose up elevator pressure.\n3. You should not increase the airspeed cause it might make the situation worse. Cause in dive with increased airspeed is always difficult to maintain the aircraft control. And you might end up with overstressing the elevator which is not good at all in such condition."}}},{"rowIdx":13,"cells":{"qid":{"kind":"number","value":2093466,"string":"2,093,466"},"question":{"kind":"string","value":"I understand that division by zero isn't allowed, but we merely just multiplied $f(x) = 1$ by $\\frac{x-1}{x-1}$ to get $f(x) = \\frac{x-1}{x-1}$ and $a\\cdot 1 = 1\\cdot a = a$ so they're the **same function** but with **different domain** how is this possible?\n\n*Or in other words* why don't we simplify $f(x) = \\frac{x-1}{x-1}$ to $f(x) = 1$ before plotting the points.\nIs it just defined this way or is there a particular reason ?\n\n**Note:** my book says the domain of $f(x) = 1$ is $\\mathbb{R}$ and the domain of \n$f(x) = \\frac{x-1}{x-1}$ is $\\mathbb{R}$ except $1$."},"date":{"kind":"string","value":"2017/01/11"},"metadata":{"kind":"list like","value":["https://math.stackexchange.com/questions/2093466","https://math.stackexchange.com","https://math.stackexchange.com/users/406041/"],"string":"[\n \"https://math.stackexchange.com/questions/2093466\",\n \"https://math.stackexchange.com\",\n \"https://math.stackexchange.com/users/406041/\"\n]"},"response":{"kind":"string","value":"They are the same *almost everywhere*.

I am not looking for a solution in `moment`.\n\nIt seemed like using `dayjs` I could solve this problem quite easily, however, I could not find a way to accomplish this.\n\nI can use UTC timezone by using [`dayjs.utc()`](https://day.js.org/docs/en/plugin/utc) or using [`dayjs.tz(someDate, 'Etc/UTC')`](https://day.js.org/docs/en/timezone/timezone).\n\nWhen using `dayjs.utc()`, I cannot use/specify other timezones for *anything*, therefore I could not find a way to tell `dayjs` I want to set hours/minutes in a particular (non-UTC) timezone.\n\nWhen using `dayjs.tz()`, I still cannot define a timezone of time I want to set to a particular date.\n\n### Example in plain JS\n\nMy locale timezone is `Europe/Slovakia` (CEST = UTC+02 with DST, CET = UTC+1 without DST), however, I want this to work with any timezone.\n\n```js\n// Expected outcome\n// old: 2022-10-29T10:00:00.000Z\n// new time: 10h 15m CEST\n// new: 2022-10-29T08:15:00.000Z\n\n// Plain JS\nconst now = new Date('2022-10-29T10:00:00.000Z')\nconst hours = 10\nconst minutes = 15\nnow.setHours(10)\nnow.setMinutes(15)\n\n// As my default timezone is `Europe/Bratislava`, it seems to work as expected\nconsole.log(now)\n// Output: 2022-10-29T08:15:00.000Z\n\n// However, it won't work with timezones other than my local timezone\n\n```\n\n### (Nearly) a solution\n\n***Update: I posted a working function in [this answer](https://stackoverflow.com/a/74245936/3408342).***\n\nThe following functions seems to work for most test cases, however, it fails for 6 4 cases known to me (any help is greatly appreciated):\n\n* [DST to ST] `now` in DST before double hour, `newDate` in ST during double hour;\n* [DST to ST] `now` in DST during double hour, `newDate` in ST during double hour;\n* [DST to ST] `now` in ST during double hour, `newDate` in DST during double hour;\n* [DST to ST] `now` in ST after double hour, `newDate` in DST during double hour;\n* [ST to DST] `now` in ST before skipped hour, `newDate` in ST in skipped hour;\n* [ST to DST] `now` in DST after skipped hour, `newDate` in ST in skipped hour.\n\nI think the only missing piece is to find a way to check if a particular date in a non-UTC timezone falls into double hour. By *double hour* I mean a situation caused by changint DST to ST, i.e. setting our clock back an hour (e.g. at 3am to 2am → double hour is between `02:00:00.000` and `02:59:59.999`, which occur both in DST and ST).\n\n```js\n/**\n * Set time provided in a timezone\n *\n * @param {Date} [dto.date = new Date()] Date object to work with\n * @param {number} [dto.time.h = 0] Hour to set\n * @param

The latest release can be found [here](https://gitlab-docker-machine-downloads.s3.amazonaws.com/main/index.html).\n\n**Original Workaround/fix:**\n\nExplicitly specify the AMI in your runner configuration and do not rely on the default one anymore, i.e. add something like `\"amazonec2-ami=ami-02584c1c9d05efa69\"` to your `MachineOptions`:\n\n```\nMachineOptions = [\n \"amazonec2-access-key=xxx\",\n \"amazonec2-secret-key=xxx\",\n \"amazonec2-region=eu-central-1\",\n \"amazonec2-vpc-id=vpc-xxx\",\n \"amazonec2-subnet-id=subnet-xxx\",\n \"amazonec2-use-private-address=true\",\n \"amazonec2-tags=runner-manager-name,gitlab-aws-autoscaler,gitlab,true,gitlab-runner-autoscale,true\",\n \"amazonec2-security-group=ci-runners\",\n \"amazonec2-instance-type=m5.large\",\n \"amazonec2-ami=ami-02584c1c9d05efa69\", # Ubuntu 20.04 for amd64 in eu-central-1\n \"amazonec2-request-spot-instance=true\",\n \"amazonec2-spot-price=0.045\"\n]\n\n```\n\nYou can get a list of Ubuntu AMI IDs [here](https://cloud-images.ubuntu.com/locator/ec2/).

Often put in a nostalgic way, this term may have originated as the title of a popular song of 1924, \"Memory Lane,\" words by Bud de Sylva, and music by Larry Spier and Con Conrad. It was revived in the film *In Society* (1944), starring [Bud] Abbott and [Lou] Costello. That is where former movie actor President Ronald Reagan may have picked it up; he then used it in his 1984 speech accepting the Republican nomination, \"Well, let's take them [his opponents] on a little stroll down memory lane.\"\n> \n> \n> \n\nAmmer's chronology notwithstanding, \"memory lane\" was a familiar turn of phrase back in 1972, when Loudon Wainright III turned it on itself in his 1972 song \"Old Friend,\" from his third album:\n\n> \n> It's been so long, things are so different.\n> \n> \n> Memory lane's a one-way street.\n> \n> \n> \n\nAlthough Ammer may be correct that \"memory lane\" owes its first surge of popularity to a song from 1924, the phrase was certainly used before that time. A Google Books search finds this instance from B. M. Balch, \"[Memory Lane](https://books.google.com/books?id=syATAAAAIAAJ&pg=RA1-PA101&dq=%22memory+lane%22&hl=en&sa=X&ei=7cvEVOf9KsT6oQS0xIHgCw&ved=0CCIQ6AEwAQ#v=onepage&q=%22memory%20lane%22&f=false),\" in *Hamilton Literary Magazine* (December 1894):\n\n> \n> On the shore of vast gray sea lies an old town; so old that no records of its founding have ever been discovered, though its archives cover centuries of existence. Every wall is crumbling away. Every gable is lichen-grown and covered with moss. In the whole great city there is nothing new. Thro the centre of the town a quaint old street, paved with square blocks of various hues from a somber gray to a bright crimson, runs down to the sea. This is Memory Lane—lonely and drear to some, pleasant and gay to others.\n> \n> \n> \n\nOlder still is this instance of \"memory's lane,\" from William Bowen, \"[That Frozen Pipe](https://books.google.com/books?id=WpcVAAAAYAAJ&pg=PA79&dq=%22down+memory+lane%22&hl=en&sa=X&ei=BtDEVNiZKYj7yASty4GgBA&ved=0CBwQ6AEwADge#v=onepage&q=%22down%20memory%20lane%22&f=false),\" in *Chained Lightning, a Book of Fun* (1883):\n\n> \n> When you have come as near as may be to the frozen spot, hold the flat-iron on the pipe and settle down for ten minutes of meditation. You won't have traveled down memory's lane over half a mile before something will happen. The pipe will burst exactly on a line with your eyes, and you will have cause to wonder all the rest of your life how a gallon of water could have collected at that one point for your benefit.\n> \n> \n> \n\nA search of the Library of Congress's Chronicling America database of U.S. newspapers finds the same \"That Frozen Pipe\" story in the [*[Rayville, Louisiana] Richland Beacon*](https://chroniclingamerica.loc.gov/lccn/sn86079088/1881-04-23/ed-1/seq-4/#date1=1836&index=0&rows=20&words=down+lane+memory+traveled&searchType=basic&sequence=0&state=&date2=1882&proxtext=%22traveled+down+memory%27s+lane%22&y=12&x=16&dateFilterType=yearRange&page=1) (April 23, 1881), which gives its source as the *Detroit Free Press* (undated).

A prisoner set up in his defense an alibi, claiming that, at the time of the robbery, he was at home listening to the recital of a novel, \"The Old Baron,\" by a man named Lane, who had committed it, with other works, to memory. Lane's recitation, he said, took two hours and a half. The Attorney General holding this to be incredible, Lane began: ... After the witness had recited several pages, the Attorney General told him to stop, as he was satisfied. But the defense insisted that, as the veracity of the witness had been questioned, he should be allowed to go on. Finally a compromise was effected, Lane gave a chapter from the middle of the story and its conclusion, and the accused was found not guilty.\n> \n> \n> \n\nThe story reappeared in newspapers from Louisiana, Michigan, Minnesota, North Carolina, Ohio, Pennsylvania, Tennessee, and Washington Territory over the next five months. It also appeared, in a slightly more detailed form, in [*Frank Leslie's Illustrated Newspaper*](https://books.google.com/books?id=ZUJaAAAAYAAJ&pg=PA365&dq=%22Lane%27s+recitation%22&hl=en&sa=X&ei=AKPGVNvbIMm6ogSxyICQCw&ved=0CCQQ6AEwAQ#v=onepage&q=%22Lane%27s%20recitation%22&f=false) (January 18, 1879), with such additional details as the name of the author of *The Old Baron* (Horace Walpole) and the fact that the episode occurred in January 1847.\n\nWas \"memory lane\" influenced by the stir made in 1879 by the account of the remarkable memory of Mr. Lane of Sydney, Australia?
