![]() Add Zinc StripsĪfter removing any mildew or fungi from your roof, you may be curious about how to keep any growth from happening in the future. Once it has had plenty of time to do its job, scrub it with a soft brush and rinse the remaining cleaner. Layer it over the rust spot and let it sit for at least ten minutes. ![]() To use this simple homemade rust remover, blend the two ingredients into a paste. This formula is ideal for a necessary roof cleaning since it doesn’t expose the roof surface to harsh chemicals for an extended period.Īny type of detergent works when cleaning your roof, including mild laundry detergents, car wash cleaning solutions, and so forth. Cleaning Metal Roofing with Soapy WaterĪfter you finish rinsing your roof, it’s time to add mild dish soap to the equation. If you don’t have a power washer, then a regular garden hose also works, though you need to scrub more challenging areas by hand. Spray each metal shingle from top to bottom, letting the dirt slide down until it falls off the side of the house. Start by placing the pressure washer on a low setting. ![]() In some cases, a light rinse is all that is required to clear away the gunk and dirt left on the surface.īefore adding a mild detergent or bleach, you should clear the roof with a light spray of plain water. Pressure Washing a Metal RoofĪ pressure washer is the most common method for removing unwanted materials from the roof. Having a few types of scrubbing options to help with removing stuck-on particles and hard-to-remove dirt spares you from unwanted frustration.Įqually, wearing protective clothing when power washing prevents flying particles from harming you or getting into your eyes, as well as preventing you from slipping off the ladder when cleaning. While a power washer takes care of most grime on roofs, the job may call for a little elbow grease. The next step is to ensure you have the necessary equipment and supplies nearby. While issues like airborne dirt, pollen, and other small particles are more likely to appear on your rooftop, you may also encounter broken twigs and branches, especially if you have tall trees that hang overhead. Similar to when cleaning aluminum siding, the first step in the process is to clear away as much large debris as possible by hand. However, these amazing tips give you the peace of mind to tackle even some of the most challenging issues.

![]() The idea of a fusion-fission hybrid reactor has existed since the early 50s, with the earliest reference attributed to Russian nuclear physicist Andrei Sakharov. But while the likes of ITER, the National Ignition Facility and a host of start-ups and academic labs around the world continue to hammer away at the fusion chestnut, a decades-old alternative concept that combines fusion and fission has resurfaced. Is pure fusion truly only a matter of years away? Opinions vary due to the formidable technical challenges that remain to be solved. ![]() “This will allow fusion power to be achieved in years, not decades.” The fusion-fission hybrid concept Regardless of Tuesday's announcement, however, the technology is still a far way off from producing energy on an industrial scale, and cannot therefore be relied on as an immediate solution to the climate crisis.“The ST40 is a machine that will show fusion temperatures are possible in compact, cost-effective reactors,” said Tokamak Energy CEO Dr David Kingham. "It is an energy source that is totally carbon-free, generates very little waste, and is intrinsically extremely safe," according to Lefebvre, who says fusion could be "a future solution for the world's energy problems." Nuclear fusion also produces much less radioactive waste than current power plants, and above all, emits no greenhouse gases. is not perfect," the reaction will simply stop, Lefebvre says. ![]() "If a few lasers are missing and they don't go off at the right time, or if the confinement of the plasma by the magnetic field. Unlike fission, fusion carries no risk of nuclear accidents. The NIF's success has sparked great excitement in the scientific community, which is hoping the technology could be a game-changer for global energy production. To get there, researchers must first increase the efficiency of the lasers and reproduce the experiment more frequently. "A few decades of research on the underlying technologies could put us in a position to build a power plant." "There are very significant hurdles, not just in the science but in technology," Budil said. LLNL director Kim Budil cautioned that much remains to be done before it can be commercially viable. Inertial confinement is used to demonstrate the physical principles of fusion, while magnetic confinement seeks to mimic future industrial-scale reactors.įor decades, scientists had attempted to achieve what is known as "net energy gain"-in which more energy is produced by the fusion reaction than it takes to activate it. This is the technique used by scientists at the National Ignition Facility (NIF) at Lawrence Livermore National Laboratory (LLNL) in California who were behind Tuesday's announcement. This is the type of reactor used in the major international project known as ITER, currently under construction in France, as well as the Joint European Torus (JET) near Oxford, England.Ī second method is inertial confinement fusion, in which high energy lasers are directed simultaneously into a thimble-sized cylinder containing the hydrogen. Magnets confine the swirling plasma gas, preventing it from coming into contact with the chamber's walls, while the atoms collide and begin fusing. In a huge donut-shaped reactor, light hydrogen isotopes (deuterium and tritium) are heated until they reach the state of plasma, a very low density gas. One method is to "confine" the fusion reaction with magnets. This is the problem of containment," Erik Lefebvre, project leader at the French Atomic Energy Commission (CEA), told AFP. "So we have to find ways to isolate this extremely hot matter from anything that could cool it down. Producing fusion reactions on Earth is only possible by heating matter to extremely high temperatures-over 100 million degrees Celsius (180 million Fahrenheit). "Controlling the power source of the stars is the greatest technological challenge humanity has ever undertaken," tweeted physicist Arthur Turrell, author of "The Star Builders." Two light hydrogen atoms, when they collide at very high speeds, fuse together into one heavier element, helium, releasing energy in the process. In fact, fusion is the process that powers the sun. Here is an update on how nuclear fusion-which produces no greenhouse gases and leaves little waste-works, what projects are underway and estimates on when they could be completed:įusion differs from fission, the technique currently used in nuclear power plants, by fusing two atomic nuclei instead of splitting one. The US Department of Energy announced on Tuesday that it had made a historic breakthrough with what some consider to be the energy of the future. ![]() Maybe I’ll end up going back to merging, maybe I’ll find some more subtle advantages to rebasing and it’ll stick. My main issue is unfamiliarity with rebasing, so I’m going to use it for a while and see how I get on. ![]() Merging respects the timeline of when things were done, but I’m happy to sacrifice that authenticity in the name of tidiness and scanability. Yes, it rewrites history, but it doesn’t change the time stamps on the commits, just the order that the commits appear in the log. Another personal one: fixing any conflicts is totally unfamiliarįor me, the big advantage of using rebase over merge looks to be that I can quickly and easily see exactly what I’ve been doing with a git log.You can’t push commits to the remote as, after a rebase, the histories are different – a force push ( git push -f origin example-branch) is needed to which overwrite the history on the remote with that of the local.Rebasing rewrites history, so even if commits that are being merged in were made after those in the feature branch they’re placed before (under) them.Open the Git tool window Alt 09 and switch to the Log tab. It’s easy to see what has been done as it puts new work at the top of the git log In the Branches popup (main menu Git Branches ), select the target branch that you want to integrate the changes to and choose Checkout from the popup menu to switch to that branch.Rebasing is tidy it doesn’t create merge commits, so there’s not clutter in the log.It can be difficult to find the new work with git log, as the commits may be peppered amongst other work in the timeline this is especially true if changes have been made sporadically over a long-ish running branch.Clutter – merging one branch into another creates a merge commit, so there will be merge commits whenever work has been merged in.A personal one: conflicts are relatively straightforward to fix mainly because I’m familiar with the process.Respects the timeline of when commits were made.Here’s a quick run-down of the pros and cons of each. Now that I’ve been using the command line for Git for over 6 months, I’ve begun to think differently about using merge like that. Merging is what I always did, and so continued to do when I moved to the command line. You can rebase in GUIs like Tower, but merging was so easy that I never really felt the need to take it for a test run. This merged the changes in and highlighted any conflicts that arose. master) onto the currently checked-out branch. With the application I used for Git, getting things up to date was as easy as dragging a branch (e.g. One thing I’ve heard a bit of noise about whether git rebase is better than git merge to get a branch up to date and pre-emptively fix any merge conflicts before a pull/merge request (PR) is raised. I’ve been thinking a lot about Git over the last 6 months since moving from a GUI to the command line. ![]() ![]() But it served as a welcomed change to the franchise. That's the one complaint I have with Dalton, he never sold me on any of his relationships in either of his two films.ĭalton is a rougher Bond than his predecessors and so are his two films. I don't think Moore or Connery would have pulled off the Rogue Bond as well as Dalton, but they always pulled off the romances. The action is fantastic for the most part including a seemingly Raiders of the Lost Ark inspired end chase sequence and not a single ski chase! Although there is one underwater action scene, but it's not as distracting as years past. Plus, Q has a bigger role which is always warranted with Desmond Llewelyn. Bond goes Rogue from MI6 and goes undercover under Sanchez in hopes of taking his entire operation down.Īlthough him leaving MI6 doesn't do much to help the story because he usually works by himself out in the field after getting a mission, the film felt different anyway. It's a different take on the Bond story and one that Quantom of Solace somewhat follows years later. After Bond finds out that Leiter is close to death and his wife's murder, he sets out on a path of revenge. The drug lord, named Franz Sanchez, also murdered Leiter's wife after feeding Leiter to the sharks. His best friend Felix Leiter of the CIA, who he just helped take down a drug lord, was left for dead right after his own wedding. I don't think it's a coincidence considering how big of a fan Christopher Nolan is of the franchise. One that closely resembles the opening scene of 2012's The Dark Knight Rises. We begin with an electrifying pre-credits sequence. ![]() Yes, sometimes the deaths can be a little jarring in terms of Bond's history, but the dark tone was needed for the story they were trying to tell. Some people say that was the downfall of the film from the beginning. It also marked the first time a Bond film was absolutely not full of humor and tongue and cheek in tone. It was the last for Dalton as 007, Robert Brown as M, Caroline Bliss as Moneypenny, and plenty more behind the scenes people as well. Licence to Kill marked the end up of a lot of things for Bond. If only the producers lightened up the character a bit and found the winning formula, Dalton's otherwise ace version of 007 might've booked passage to GoldenEye rather than just dying in development another day. Still, the explosions and chases keep this off-the-grid caper intense in the right ways as well. Dalton's 007s gets locked on intensity even more than his previous outing, which brings the tone down more than makes the character dirty. It demonstrates an unsureness that shows up in many aspects of this production. Reportedly having little faith in the ability of American audiences to understand the meaning of the word "revoked," the Brits went with the much more marketable phrasing License to Kill. The fact that the producers changed the title from License Revoked says everything about this middling attempt to make Bond go dark. agent, and left him for dead and murdered his bride after he helped capture him. In this PG-13-rated spy thriller, James Bond (Dalton) goes rogue and sets off to unleash vengeance on a drug lord (Davi) who tortured his best friend, a C.I.A. Featuring explosively thrilling action scenes and Benicio Del Toro in a breakout role, the film's worst offense (it still holds the record as the lowest earning Bond in the franchise) is debuting in a pre-9/11 world where Michael Keaton - not Christian Bale - assumes Batman's cowl. Yes, Casino Royale shakes and stirs Bond into pitch blackness, but License to Kill tries it first and to mostly good effect. Arming 007 with a rousing amount of darkness and edge, the first PG-13-rated Bond film finds Dalton in top form and the series getting down and dirty. ![]() ![]() The premise kills off Batman so that the sidekick cast can spend the whole plot struggling to live up to and transcend him. It's a weird mix of cash-in and act of rebellion. It tries to stand apart from Rocksteady's Arkham games - still probably the best superhero adaptations on offer - while also riding their Kevlar coat-tails. Which is to say, it feels like it was bolted-together by committee circa 2016-2017, using pieces popularised by the original Destiny and Ubisoft's The Division - open world RPG looting and progression conventions that had long since become a laughing stock when Gotham Knights actually launched in 2022.īad timing aside, Gotham Knights also has classic "resentful younger sibling" syndrome. In key respects, Gotham Knight isn't so much a bad game as an OK game that had the misfortune to be left standing when the music stopped, the music in question being that classic mid-tensies number "Phat Loot and Gear Tiers", from folk rock outfit Bungie. But I find myself itching to download and revisit this muddled open world contender all the same. In his RPS review, Ed Thorn described it as "an action-RPG that wraps what could've been a wonderfully realised Gotham universe in a tired, slapdash mix of meaningless numbers and loot." I reviewed it myself as a freelancer and can't disagree with his verdict. Warner Bros Montreal's one-four-all superhero spin-off Gotham Knights hits Game Pass today. ![]() This should definitely appease anyone out there who may have thought that the Paranormal Activity movies were just about trying to scare fans with parlor tricks. While the earlier Paranormal Activity films went for a more subtle scare approach, Landon decides to really earn his R rating with plenty of gore, nudity, language and violence. The Marked Ones has a bit of a “kitchen sink” mentality to it, which I dug as someone who grew up on a steady diet of those types of horror films from the 1980’s. However, Landon definitely makes it look easy with The Marked Ones, confidently introducing some bold new ideas that are out of left field and yet somehow, totally work. ![]() Often times in horror franchises, the higher the sequel number, the more it seems like filmmakers are left frantically trying to shoehorn in the original mythology into this new story. It’s really hard to talk about what works the best in The Marked Ones without getting into any kind of spoiler, but everything here works seamlessly within the Paranormal Activity universe and pretty much makes up for any misgivings fans may still have about its immediate predecessor. One night, Anna is killed under mysterious circumstances, which of course causes Jesse and Hector to take a look around Anna’s now vacant apartment… ![]() During one of their pranks, we’re introduced to Jesse’s oddball neighbor Anna, who everyone in the building suspects to be a bruja, since they can hear mysterious chanting and moans coming from inside her place. And frankly, I’ve never been happier to be proven wrong about a film as I am with the latest Paranormal sequel.īilled as a spin-off, The Marked Ones follows a newly graduated high schooler named Jesse (Andrew Jacobs) and his pal Hector (Jorge Diaz) who spend most of their free time taping their teenage antics on Jesse’s new camera. Hands down, The Marked Ones is absolutely relentless, creepy as hell and a ton of fun on the big screen- it totally surprised me and left me with my enthusiasm renewed. As it turns out, writer/director Christopher Landon knocks it out of the park, cleverly finding different ways to deliver up the thrills and a few surprises to boot, all while masterfully deepening in the Paranormal Activity universe. So when I had a chance to check out Paranormal Activity: The Marked Ones, I went into it with my reservations firmly in check. A rather redundant and underwhelming story made the fourth movie feel like a greatest hits reel from the films that preceded it. That was, until Paranormal Activity 4 came around in 2012 and unfortunately left a bad taste in my mouth. I’ll be the first to say that I unabashedly love the Paranormal Activity franchise. ![]() We’re proud to service Macarthur, Campbelltown, Mount Annan, Camden and surrounding areas.

The V3 Pro comes with a Razer HyperSpeed 2.4GHz wireless dongle, and is also compatible with Razer’s HyperPolling Wireless Dongle (sold separately for $30 or bundled with the V3 Pro for $165) - which upgrades the V3 Pro’s wireless polling rate to 4,000 Hz (from 1,000 Hz). The sensor tracks seamlessly on a variety of surfaces, including transparent glass. The mouse is equipped with Razer’s Focus Pro 30K Optical sensor, which has a max sensitivity of 30,000DPI, a tracking speed of 750 IPS, and up to 70g of acceleration. The DeathAdder V3 Pro may not be as flashy as other gaming mice, but it still has plenty of features packed under its ultra-lightweight hood. (To get the weight down, Razer stripped the V3 Pro of unnecessary frills, including RGB and Bluetooth). The new V3 Pro weighs just 2.22oz (63g) and features a streamlined silhouette with a split key cover design (instead of the usual unibody shell) and five programmable buttons. Razer’s DeathAdder V3 Pro sports a subtle-but-significant redesign that makes it lighter, more tactile, and more ergonomic than its predecessor, the DeathAdder V2 Pro. Read: Razer Basilisk V3 Review Best Wireless Gaming Mouse It's twice the price, of the Basilisk V3, though, and that price tag doesn't even include the Mouse Dock Pro, which was tailor-made for the Basilisk V3 Pro. The Basilisk V3 is wired, but it has a wireless counterpart: the Basilisk V3 Pro, which also sports an upgraded sensor - Razer's Focus Pro 30K Optical Sensor - as well as updated optical switches. However, this does mean the wheel can sound rattly and is particularly noisy when switching modes. Each button can also have a secondary function when using “HyperShift.” The Basilisk V3 also has a dual-mode scroll wheel that can swap from tactile to smooth, free scroll at the tap of a button or based on how you flick it. While it is on the heavier side compared to ultra-lightweight mice for FPS games, it glides well and has a dedicated sniper button that's easy to reach and drops DPI instantly for headshots.Ĭustomization options abound, from the 11 individual RGB zones to the aforementioned buttons. Its 9 (13 if you include all the scroll wheel inputs) programmable buttons, well-crafted shape, and premium, textured finish make it versatile across gaming genres and even productivity workloads.

Oh, and it will also pack a powerful sensor and near-zero latency - so you can nail the perfect headshot, every time. It will glide effortlessly across any surface you choose to play on, and will have intuitive, well-placed tactile buttons. ![]() The right gaming mouse will fit your hand and grip-style so perfectly, you'll forget you're even using a mouse. A common level for statistical significance is 5%. Building on our earlier findings, we’d like to state this constraint with a certain degree of certainty, or confidence. In order to accurately set a threshold for maximum drawdown, we’ll need to define our time horizon.įor example, we might specify that drawdown must not exceed 25% over the course of the next year (approx. ![]() Intuitively, an account’s maximum drawdown over the course of the next month will be less than its maximum over the next year. In fact, it can be shown that maximum drawdown is proportional to the square root of time (I won’t prove that out here, but feel free to work investigate it yourself!) Essentially, the longer a given series of returns compounds on itself, the greater the maximum drawdown will be. If this percentage is too great, we must use a smaller position size.Ī second important characteristic of drawdown is that it is time-horizon dependent. To do this, we calculate the percentage of scenarios in which maximum drawdown is likely exceed our risk threshold. However, we can say with some level of confidence that the maximum drawdown experienced won’t exceed our threshold. We won’t be able to totally constrain our results on expected drawdown, as the value for max drawdown could fall within a wide range. If we want to use drawdown as a risk metric, we need to deal with its inherent uncertainty. The maximum drawdown varies from less than 30% to over 70%! This is a huge range of possible values. Reordered = np.random.permutation(returns) We’ll demonstrate this below by shuffling the order of S&P returns and examining the resulting equity curves.Ĭurves = pd.DataFrame(index=returns.index) Unlike compounded returns, the value for maximum drawdown depends on the order in which returns are realized. However, there are limitations to using drawdown as a risk metric. It’s a much more visceral experience to watch one’s account balance drop from $100,000 to $50,000 one that can de-rail trading strategies. In practice, few traders base their decisions whether to follow their strategy on the standard deviation of returns or similar measures of volatility. In order to protect from the possibility of a 25% drawdown, we’d need to scale back the leverage from our optimal f value by almost 9 times!Īs noted above, drawdown is a good risk metric for practitioners because this it most directly impacts their emotions. Geometric Holding Period Return: 0.01427% Spy_f_bounded = get_f_bounded(spy_returns, drawdown_limit=25) ![]() _ghpr = _twr ** (1 / len(equity_curve)) - 1ĭf = pd.DataFrame(columns=) _drawdown = eq_series / eq_series.cummax() - 1ĭef max_drawdown(equity_curve, percent=True):Ībs_drawdown = np.abs(drawdown(equity_curve)) Source code for this value has been provided as well feel free to substitute it in. We use maximum drawdown as a proxy for risk because this is the number that investors “feel”, which tends to drive allocation decisions for emotional reasons.Īn alternative metric is the Ulcer Index, a root-mean-squared calculation based on drawdown that takes into account both drawdown severity and duration. Let’s see how increasing position size increases drawdown by constructing a curve similar to the one for GHPR for maximum drawdown. We left off with an example showing that investing in SPY at optimal f would cause some extreme discomfort along the way. Read here and feel free to follow along with provided notebook. This post will help traders maximize their gains while still getting their beauty rest! Since a 20% retracement from peak equity causes most investors to start tossing in their sleep, this approach doesn’t seem very realistic. This would have yielded the greatest compounded rate of return, but would have induced a 97% (!!!) max drawdown along the way. To realize the greatest return on capital, an investor in SPY since its inception should have used over 3x leverage to buy in. What does “optimal” mean, anyway? In the first part of this series, we discovered that the staked fraction of capital that yields the greatest compounded returns also yields a less-than-optimal level of drawdown.
