notice no HDD space is consumed with this command: # BEFORE With this you could actually create an arbitrary large file, regardless of the available space on the device, as it creates a "sparse" file.įor e.g. Will create a 10 M file instantaneously (M stands for 1024 1024 bytes, MB stands for 10001000 - same with K, KB, G, GB.)ĮDIT: as many have pointed out, this will not physically allocate the file on your device. Most Linux systems also have fallocate, which only works on certain file systems (such as btrfs, ext4, ocfs2, and xfs), but is the fastest, as it allocates all the file space (creates non-holey files) but does not initialize any of it. It's included in xfsprogs (for Debian/Ubuntu) or similar named packages. Most Linux systems have xfs_mkfile which works exactly the same way, and not just on XFS file systems despite the name. Mkfile is derived from SunOS and is not available everywhere. Without the -n option, the space is zero-filled, which means writing to the disk, which means taking time. With the -n option the size is noted, but disk blocks aren't allocated until data is written to them. Try mkfile myfile as an alternative of dd. Prealloc 10Gigfile 10737418240 Explanation Xfs_mkfile 10240m 10Gigfile Linux & and some filesystems (ext4, xfs, btrfs and ocfs2)įallocate -l 10G 10Gigfile OS X, Solaris, SunOS and probably other UNIXes So, when you use fallocate to create a 20 GB virtual drive space, you really do get a 20 GB file (not a "sparse file", and you won't have bothered to write anything to it - which means virtually anything could be in there - kind of like a brand new disk!) E.g.: fallocate -l 10G gentoo_root.img E.g.: truncate -s 10G gentoo_root.imgįallocate is the final - and best - choice for use with VM disk allocation, because it essentially "reserves" (or "allocates" all of the space you're seeking, but it doesn't bother to write anything. Thus, when you use truncate to create a 20 GB drive for your VM, the filesystem doesn't actually allocate 20 GB, but it cheats and says that there are 20 GB of zeros there, even though as little as one track on the disk may actually (really) be in use. Essentially, a sparse file is a section of disk that has a lot of the same data, and the underlying filesystem "cheats" by not really storing all of the data, but just "pretending" that it's all there. But that is because it creates a "sparse file". Truncate is another choice - and is likely the fastest. E.g: dd if=/dev/zero of=./gentoo_root.img bs=4k iflag=fullblock,count_bytes count=10G (Want to make it take even longer? Use /dev/random instead of /dev/zero! Then you'll use CPU as well as I/O time!) In the end though, dd is a poor choice (though essentially the default used by the VM "create" GUIs). And that initialization is what takes up so much I/O time. Unfortunately, the answer is not as straight-forward as one might assume.ĭd is the obvious first choice, but dd is essentially a copy and that forces you to write every block of data (thus, initializing the file contents). Hi guys,I have a problem with a fortigate 100f, when a websited is blocked, it is not showing the webfilter error message, it is only saying connection reset.Investigating a little bit, i found out that disabling app control will do the trick.Is there any.This is a common question - especially in today's environment of virtual environments.

I told him that plan was to move it to a new fileserver and shar. new IT boss saying move it to sharepoint and setup permissions for each group. We have good amount of data (900 gb) sitting on one user's computer, its shared and mapped to other users. Then I tried, in the timeline panel, changing the motion from "custom" to "rotate", but the problem this time was that when i tried rotating it, it disregarded my anchor point no matter where I dragged it to and just rotated around the middle. I move my ticker over the keyframe, hit ctrl+T, and rotate, but the rotation is applied to the entire animation and not just that keyframe. Now duplicate that hand layer, and enter FreeTransform again: drag the center marker to the bottom center handle, and it will rotate around that point. I set my keyframes up accordingly, and the position animated just fine, but I'm having serious trouble with the rotation. Bottom line: I want to animate the rotation and position of a layer. Hold Alt/Option key and click on the eye icon of the layer to hide all layers except the one you clicked on. The trick to automatically get back to the Burn Tool is this. Select the layer you want to rotate by clicking on it in the Layers panel. Basically, I want each leg component to rotate every time he takes a step, and for the position of the leg component to change as he's moving forward. If you hold R key and click and drag to rotate, when you release the mouse and the R key, Photoshop will stay at the Rotate Tool. To rotate a layer, you’ll first need to: Step 1. This may seem like an extremely amateurish question but today I've been having the hardest time making an animation of a person walking using keyframes in photoshop timeline animation. In Photoshop, you can easily rotate images or rotate layers very quickly. And if Plug Power as a business performs well, the stock will surely follow. These will undoubtedly expand the group’s reach, which could translate into greater market share capture. Needless to say, if this milestone is hit, profitability might soon enter the picture.Īside from that, management announced multiple partnerships and strategic acquisitions in 2021. And analyst forecasts expect the group to generate $900m-$925m in revenue in 2022, reaching as high as $3bn by 2025. In the past year, Plug Power won several projects worldwide, including a 250MW order from Fortescue. In 2021 it generated $502m in revenue – $162m of which came from the fourth quarter alone.įurthermore, the group launched a Gigafactory in Rochester, New York, to help solidify its position in the alternative energy market. The company recently reported the largest quarterly and annual revenue in its history. This hydrogen stock has managed to increase its revenue over the years – a trend that I believe will continue moving forward. Plug Power Stock: What do the numbers say? That being said, do the financials suggest that Plug Power is a good stock to buy? These products are provided worldwide through direct product sales and leveraging relationships with original equipment manufacturers (OEM) and their dealer networks. GenSure, GenKey, ProGen, and GenFuel Electrolysers.GenFuel – a liquid hydrogen fueling delivery, generation, storage and dispensing system.GenDrive – a hydrogen-fueled PEM fuel cell system.Looking at its product portfolio, the group currently has: This is amidst an ongoing paradigm shift in the power, energy and transportation industries to address climate change and energy security, while meeting sustainability goals. The company’s innovative technology powers electric motors with hydrogen fuel cells. These are predominantly used for material handling and stationary power markets. It provides alternative energy technologies by focusing on designing, developing, manufacturing, and commercialising hydrogen and fuel cell systems. Plug Power was founded in June 1997 with Headquarters in Latham, New York. With that said, let’s dive in to see or remind ourselves of what this business actually does. So, does that mean I should buy or sell Plug Power stock today? One thing which I do is to invest only in companies I understand. But compared to where it was in November 2021, the business has taken quite a tumble. By comparison, the S&P 500 index is down 7.8% in the same period.

Later, David joined Big Boss's special forces unit FOXHOUND, during which time he received the codename "Solid Snake." While undergoing FOXHOUND's training regimen, he became an expert of high-altitude skydiving, linguistics, closed-circuit open-circuit combat diving, and free climbing. soldiers were injected with soldier genes in an attempt to replicate the results of Les Enfants Terribles, making them, and the reported "Gulf War Babies," David's siblings, in a sense. Making his way into the military, David was inducted into the Green Berets as a teen and took part in a mission to infiltrate western Iraq in 1991, during the Gulf War. He spent his early life being raised in the United States by a variety of foster parents. A third clone was created afterward.įollowing his birth, Solid Snake was given the name David. Being a somatic cell clone of Big Boss, Solid Snake inherited mitochondrial DNA from the Japanese egg donor of "Les Enfants Terribles," later demonstrating some awareness of this heritage. Nine months later, the twins were born and would later receive the codenames of Solid Snake and Liquid Snake. The two clones were also modified on the genetic level, with one clone expressing Big Boss's dominant genetic traits and the other expressing Big Boss's recessive traits. By utilizing the Super Baby Method, the embryos were then implanted into the womb of a surrogate mother with six of the babies eventually being aborted to promote growth in the remaining two. Using the process of somatic cell nuclear transfer, eight clone embryos were created by inserting Big Boss's DNA into enucleated egg cells, donated by a healthy Japanese woman. The twins were also to serve as an insurance policy for the Patriots, should Big Boss abandon their organization. In 1972, David and his twin brother Eli were born as a result of the secret government project "Les Enfants Terribles," designed to create the perfect soldier, using the genes of the "Greatest Warrior of the 20th Century" Big Boss. In 1970, Solid Snake was foreseen in a prophetic vision by Elisa and Ursula as the son of Big Boss that would "save the world." Non-"Metal Gear Saga" information ends here.

In 2014, Snake performed his final mission, during which he defeated Liquid Ocelot and destroyed the Patriots. During this time, his health declined as his body entered a state of accelerated aging due to intentional genetic changes made during the cloning process. He faked his own death in the Manhattan Tanker Incident, though he re-emerged years later to assist Raiden in the Big Shell Incident. Repeatedly tasked with disarming and destroying the latest incarnation of Metal Gear, a bipedal nuclear weapon-armed tank, Snake would thrice avert potential nuclear catastrophe, becoming a famed war hero.įollowing the Shadow Moses Incident and subsequent smear campaign by the Patriots, the secret organization behind American politics, Snake was labeled a terrorist. Initially a Green Beret, Snake was later inducted into the High-Tech Special Forces Unit FOXHOUND in the 1990s while it was commanded by Big Boss. He was created as a clone of the world-renowned soldier Big Boss, along with his brothers Liquid Snake and Solidus Snake. Snake was one of the children born of the 1972 project Les Enfants Terribles. Possessing an IQ of 180 and fluent in six languages, the fame he achieved from his military exploits earned him such monikers as "Legendary Soldier," "Legendary Hero," and "the Man Who Makes the Impossible Possible."

There are many methods to compressing a PDF on Windows 10, both offline and online. In PDF Pro: File menu > Optimize > Optimize the document and reduce its size > Optimize Compress & Optimize Any PDF on Windows 10Ĭompressing PDFs before sending or emailing them is important, especially when dealing with larger file sizes. The easiest way to make a PDF smaller is by using a PDF editor like PDF Pro, and optimizing the PDF to reduce the size of the file, while maintaining good quality. But if you “zip” your PDF in a compressed “zip” folder, then the PDF will be able to be extracted from the folder in the same size and quality - quality of the content will not be affected. If you optimize a PDF by reducing the size of the file itself, then the quality will be reduced a bit. Right-click the PDF you want to compress.So you’d still need to unlock the PDF normally before being able to open or edit it. It’s possible to compress an encrypted or locked PDF even if you don’t know the password, however compressing a PDF will not bypass security settings, such as passwords. Choose the location that you want to store the compressed PDF, then press Save.You now have a compressed (zipped) folder containing your compressed PDFs that you can email, send online, etc. In Google Drive, select the PDFs with your mouse (press and hold on your keyboard to select multiple files).

How to Compress a PDF to EmailĪttaching and sending PDFs via email is one of the most common reasons why people compress PDF files.ġ. We’ve listed the most helpful methods that are available to Windows 10 users. There are multiple ways to compress and reduce the file size of a PDF. Note: some quality loss may occur (especially image-heavy files), but modern PDF editors can balance compression while retaining a lot of quality. The PDF is optimized and the file size is reduced, so you can send the PDF as is. This truly compresses a PDF file, itself. This preserves the quality of the PDFs, since they can be “unzipped” after being received. There are two types of compressed PDF files: 1. The main reason to compress a PDF (or any file) is to reduce the size of the file to make it easier to send online.

Now notice that I needed to add a pop to the variable since now it keeps the elements after the call to the function.Īlso I needed to use the nonlocal term so the function will know the cur variable. Yield from permutations_with_replacement_rec(n, m) Yield from permutations_with_replacement_rec(n_rec - 1, m_rec) This is how it turned out: def permutations_with_replacement(n: int, m: int) -> Iterator]:ĭef permutations_with_replacement_rec(n_rec: int, m_rec: int) -> Iterator]: I created a sub function that is recursive taken out the cur variable. So you said you do not like the way cur is implemented in your code, I thought of a way to take it out of the function declaration. Since it's a generator it should be: Iterator]. I added type annotation to the return value of the function.I do not think n and m should be in main.Is there any better way to do that?įirst of all, this is a very nicely written code.īefore writing about the cur implementation, a few notes: I don't like the way I've implemented cur in my code. The arguments to the constructor are the elements of the permutation’s word representation, i.e., the images of the integers 1 through some n under the permutation. There's a better way to do this if we used itertools.product, but there's no fun in that! from itertools import productįor i in product(list(range(1, m + 1)), repeat=n): A Permutation object represents a permutation of finitely many positive integers, i.e., a bijective function from some integer range 1, n to itself. If x is an integer, randomly permute np.arange(x).If x is an array, make a copy and shuffle the elements randomly. Yield from permutations_with_replacement(n - 1, m, cur + )įor i in permutations_with_replacement(n, m): permutation (x, axis 0) Randomly permute a sequence, or return a permuted range. So, I've written a function to do just that: from sys import setrecursionlimitĭef permutations_with_replacement(n: int, m: int, cur=None): I have looked at the random library but couldn't find something that fits my need.Many a times, I've had the need to use a permutations with replacement function. The permutations command from itertools generates all the possible permutations which in my case are too many to handle. I could not figure out or find a way to do this. (Or find a trade off between memory usage and the looping, so maybe do 5 loops for 4000 shuffles at the time). Therefore I though about trying to generate a 2D array of shape (len(ys),20000) with essentially 20000 shuffled ys array, and then access them at ones and calculate the 20000 differences (diff in the code). I am looking to speed up the permutation test code. Permutation importance is one of the most reliable ways to see the important. The two loops (within (lon,lat) and for 20000 shuffles) adds up. Think of those Python one-liners that are dreadful in terms of readability. Ideally I want to run a permutation test with 20000 permutations. I run it using eratools: for ii in om_iterable(zip(*dataset.variable())):ĭataset.perm_test = exact_mc_perm_test1(iis, ii.values, 1000.,selected_position) the dataset has (lon,lat,time) coordinates, I need to run it for each (lon,lat) position (along the time dimension) I have to run it over a 3D array stored in an xarray. I took this SO answer and modify it for my specific test. # difference now between fixed all time series and shuffled subsamplevaluesĭiff_shuffled = np.abs(np.mean(ys) - mean_ys) Two such features Ive discovered recently are the permutations and combinations functions of Pythons itertools module. We will be using the combinations () and permutations () methods under the itertools module of Python. We will look at sets of characters and numbers. My code: def exact_mc_perm_test(ys, nmc,boolean_selection):ĭiff = np.abs(np.mean(ys) - mean_ys) In this tutorial, we will learn how to get the permutations and combinations of a group of elements in Python. This method is defined in itertool package. However I have to repeat it many times, and it is taking a too long time. Python provides one utility method to find out the permutation of a iterable. I developed, thanks to many SO questions, a decent permutation test routine. I have browsed SO extensively and I have found many questions about generating all possible permutations, but none regarding generating a specific number of permutations. |
