Typical response times are running in the 6ms range, 20 is quite generous, 500 is merely catastrophic, which is all I need. If this starts to show good, reliable performance then I can tighten up the warning and critical limits although that may be unnecessary. That revelation, combined with the knowledge that an explicit IPV4 flag is available, and the lack of any documentation on or control of the ping size for check_ping, I’ve switched back to check_icmp with the following custom parameters: I suspect that this might have something to do with the problem. However, now armed with your information, I was able to appreciate that the default check_icmp ping size is 68, which is not the normal Linux size of 56 (in both cases without the additional 8 bytes of the ICMP header). Overnight the host in question seemed to do better with check_ping instead of check_icmp. And that is some super important and super basic stuff, too. That is phenomenally helpful information! I searched and searched through the CheckMk documentation, and this forum, and found none of that. However, this did not help at all… Very interesting. # The following are taken from OSD network tuning I have put the following into /etc/sysctl.d/nf followed by a sysctl -w -p /etc/sysctl.d/nf. However, I have seen problems with default configuration of Linux hosts with many network connections before (Ceph on RHEL based distros). I found it a bit hard to imagine that something like ping/ICMP in particular is an issue. This is a shot into the dark - which amounted to nothing.

How to convert cubic light years to cubic parsecs ly³ to pc³. The year used by the International Astronomical. A light year is the distance that light travels in one year. It is exactly 648,000 / Pi astronomical units, or approximately 30.9 trillion kilometers. A parsec is a unit of distance used in astronomy. That means it can measure, to within 20 percent accuracy, the distances of stars that lie tens of thousands of light-years away.RED ENCHILADA SAUCE, UPC: 021130502585 weigh(s) 254 grams per metric cup or 8.5 ounces per US cup, and contain(s) 42 calories per 100 grams (≈3.53 ounces) Ģ09328 foods that contain Total lipid (fat). How long is 750 parsecs in light years 750 pc to ly conversion. The European Space Agency’s Gaia mission, currently underway, can measure parallax angles of just a few millionths of an arcsecond. That’s why a parsec has that value, and not any other.Īlthough astronomers often measure distant objects in parsecs or megaparsecs (1 megaparsec is 1 million parsecs), only nearby objects have parallaxes that we can actually measure. And a parsec is the distance - 3.26 light-years - that a star must lie from the Sun for its parallax angle to be exactly 1″. 1 parsec (pc) is equal to 3.26156 light years (ly) 1 light year (ly) is equal to 0.306601 parsecs (pc) parsec to light year Formula: When it comes to conversions from pc to ly, all you need to consider this basic math’s formula: The formula for parsecs to light years is: ly pc 3.2616. The two different sightlines, one at each end of Earth’s orbit, create a triangle the parallax angle is defined as half the angle at the triangle’s apex. If you draw a simple diagram, you’ll see that the distance the star appears to move is related to the angle at which it is viewed. Translated to the stars in the sky, two photographs of the same nearby star taken six months apart will show it appearing to move against the background of more distant stars because Earth has moved to the other side of the Sun in its orbit. Your finger will appear to shift because each eye views it from a slightly different angle. Next, open your left eye and close your right. Close just your left eye and observe where your finger appears against the background. One of the simplest ways to see for yourself how this works is to hold your hand at arm’s length in front of your face and raise one finger. This is because as our planet moves, our viewpoint changes. Distance from the Sun to an astronomical object with a parallax. 1 Parsec is approximately 3.085 677 82 x 10 16 ☖ x 10 6 meters (SI unit).

Question: Why is a parsec 3.26 light-years and not some other number?Īnswer: A parsec, or “parallax second,” is defined as 3.26 light-years because of how it is measured. The experience becomes like a story that uses a map. What’s more, the Voyager feature allows users to select areas to explore. They offer cool information about the location you’re visiting virtually. Lately, Google has added what they call Knowledge Cards to the program. Google Earth is more of an experience than a map provider. Google Maps in Use Google Earth and Exploration The images are not overly detailed, but you can get an understanding of what the surface of these extraterrestrial bodies is like. Since it’s not limited to Earth, you can also explore the surface of Mars and the Moon with Google Maps. This way, you can both enter the restaurant at the same time. He can share his location, and you can follow along with him as he moves closer. For instance, your friend calls to say he’s on his way to the restaurant you’ve planned to meet at.

It can help anyone get around almost everywhere. The information that Google Maps provides is up-to-date and on the cutting edge of software. None of the sellers have pictures of the book either. I talked to a couple of book sellers on Alibris because some list their book as "Gregg Shorthand Dictionary" another one was listed as "Gregg Shorthand Simplified Dictionary". I'm still looking for the correct and latest Gregg simplified dictionary. It still has to be opened in the special reader, but the outlines won't appear properly in the epub version. Also, if you decide to check it out, choose the pdf version. You have to create an account, but it's all free. If you go to there is a Simplified dictionary that can be read online or checked out for a couple of weeks and read in Adobe digital editions. Today I've been thinking about getting another one and penciling in my preferred outlines beside the printed one whenever it differs. Not only does it have so many words, but it has every nearly every geographical or given name I have ever looked for. After discovering the Anniversary edition of Gregg Shorthand, I gave up the Simplified books almost entirely. If there were any bugs, surely subsequent printings had them worked out. I would say everything else being equal–price and condition–don't get the oldest edition. I have owned several copies (because of moving a lot and a hoarding instinct) but I never noticed any differences in them–that doesn't mean there weren't any, but I didn't find any. I'm not up on editions of this dictionary, but I know it was published for several years, and this is a great dictionary, btw. Why Drawdown is important When you compare 2 trading systems, a. Whether you are looking for a retirement score or a retirement income calculator, Fidelitys retirement tools & calculators can help you plan for your. This is probably because of the multiple iterations involved.ĭoes anyone has a suggestion for a max drawdown calculation with better performance? Thanks in advance. If youre getting a higher drawdown value than the previous value, you have a new max drawdown. If a table gets a bit larger then the formulas are running forever and finally a memory error occurs. In a test table with few rows these formulas are working correctly. The problem is the performance. Lastly, I calculate the max drawdown with this measure: Peak:=MAXX(FILTER(ALLSELECTED('Calendar') 'Calendar'<=MAX('Calendar')) ) Calculating maximum drawdown in Excel can give investors a clear picture of the risk and potential losses associated with their investments. It refers to the largest peak-to-trough decline in the value of a portfolio. He codes it in MATLAB, but I wanted to try my hand at the same code in Python. Then, I calculate the peak in the cumulative profit with this measure: Learn about the Calmar Ratio, and download an Excel spreadsheet to calculate this performance benchmark. When it comes to investment analysis, maximum drawdown is a crucial metric to understand. Chans book, Im attempting to calculate the maximum drawdown and the longest drawdown duration from cumulative portfolio returns. A maximum drawdown (MDD) is the maximum loss from a peak to a trough of a portfolio, before a new peak is attained.įirst, I calculate the cumulative profit with this measure:Ĭumulative Profit$:= CALCULATE( FILTER(ALLSELECTED('Calendar') 'Calendar'<=MAX('Calendar'))) Step 3: Use the MIN function to find the trough. Step 2: Use the MAX function to find the peak value of the investment returns. Drawdown calculator Risk of Ruin Calculator Pivot Point Calculator Fibonacci. Step 1: First, organize the investment returns in a column in Excel. I am trying to calculate the Max Drawdown in a table of trades. When calculating the maximum drawdown, these functions can be used to identify the peak and trough points in a time series of investment returns. and 25 lbs of LR would displace 25 /4 = 6.25 gals of water. 1 pound of LR displaced 1 quart of water, then 4 lbs displaces 1 gal. You would now know how much that piece weighed and how much water it displaced, just like the sand. If you have other objects within the tank (gravel, rocks, ornaments), water will be. Weigh a small piece and put it in the beaker and look at its displacement. Please remember that the tank volume is calculated for an empty tank. You could do the same thing to get maybe close enough. This will not be as easy with LR as you have many sizes. Some say the tank manufacturers inflate their listed tank volume because they use outside dimensions instead of internal, and I know MarcoRock is dense and heavy, so maybe displaces more water than others or live rock, but then the MarinePure Blocks are super porous and probably don't displace much water at all. and 25 lbs of sand would displace 25 /4 = 6.25 gals of water. Find out how many litres of water your fish tank can hold with our water volume calculator, which can also work out how many fish can fit in your aquarium. If say, to be simple, 1 pound of sand displaced 1 quart of water, then 4 lbs displaces 1 gal. Simply measure the average height, width and depth of your pond using a measuring tape and input the measurements into our pond size calculator. Juwel Vision 180 LED Tropical Aquarium & Cabinet. You also need to weigh the sand before you add it into the beaker. This means that a pump rated for 1000 GPH will probably only deliver about 500 GPH back to your aquarium once it is installed. This plumbing applies pressure to the pump and reduces the amount of water being delivered. This will show how much the sand displaces the water water. A return pump will typically need to pump water through 4-6 feet of plumbing and an elbow or two. In that video, low flow is defined at 10-15X. Then I watched a good video from Vivid Aquariums. You can figure this by talking a beaker again and filling it say half way with water, then putting in some sand and and checking the new water level. In another good video, this time by Marine Depot, they said they recommend 10-20X tank volume total turnover for a low flow tank, 20-40X tank volume total turnover for a medium flow tank, and > 40X for a high flow tank. Hard to say as it is a big function of porosity, meaning how much void space. Step 3 - Input current Alkalinity, Calcium or Magnesium levels. Step 2 - Select your supplement/additive brand from the conclusive list. If you are trying to heat a 10-gallon aquarium that is going to be completely different compared to if you are trying to heat a 75-gallon tank. I would suggest to get a graduated beaker, that has vol. Step 1 - Enter your tank water volume using the control panel.

For years, China largely focused its state-sponsored hacking on espionage, even as other nations like Russia and Iran have attempted to breach electrical utilities in apparent attempts to plant malware capable of triggering tactical blackouts. More broadly, Hultquist sees the RedFly breach as a troubling sign that China is shifting its focus toward more aggressive targeting of critical infrastructure like power grids. And given recent warnings about China's hackers breaching power grid networks in US states and in Guam-and specifically laying the groundwork to cause blackouts there-O'Brien warns there's reason to believe China may be doing the same in this case. But other researchers at security firm Mandiant point to clues that these hackers may be the same ones that had been previously discovered targeting electrical utilities in India. O'Brien notes that Symantec doesn't have direct evidence that the hackers were focused on sabotaging the country's grid, and says it's possible they were merely carrying out espionage. The unnamed country whose grid was targeted in the breach was one that China would “have an interest in from a strategic perspective,” hints Dick O'Brien, a principal intelligence analyst on Symantec's research team. The breach began in February of this year and persisted for at least six months as the hackers expanded their foothold throughout the IT network of the country's national electric utility, though it's not clear how close the hackers came to gaining the ability to disrupt power generation or transmission. "For years, China has conducted aggressive cyber operations to steal intellectual property and sensitive data from organizations around the globe," CISA Director Jen Easterly said in a statement.Today, researchers on the Threat Hunter Team at Broadcom-owned security firm Symantec revealed that a Chinese hacker group with connections to APT41, which Symantec is calling RedFly, breached the computer network of a national power grid in an Asian country-though Symantec has declined to name which country was targeted. In a joint statement with international and domestic intelligence services, the Cybersecurity and Infrastructure Security Agency warned that Chinese attacks pose a continued risk to American intellectual property. In a Thursday editorial, the Chinese state-backed paper China Daily dismissed Microsoft's analysis and the intelligence community warnings as "political propaganda." Covington & Burling, a prominent law firm, was breached by suspected Chinese state-sponsored hackers in 2020. Government organizations were also targeted.Ĭhinese government-backed hackers have targeted critical and sensitive information from U.S. Infrastructure in nearly every critical sector has been impacted, Microsoft said, including the communications, transport and maritime industries. Rather, "the threat actor intends to perform espionage and maintain access without being detected for as long as possible." The state-sponsored hackers aren't looking to create disruption yet, Microsoft said. Once the hacking group has gained access to a corporate system, it steals user credentials from the security suite and uses them to try to gain access to other corporate systems. Volt Typhoon is able to infiltrate organizations using a unnamed vulnerability in a popular cybersecurity suite called FortiGuard, Microsoft said. intelligence because Guam sits at the heart of an American military response in case of an invasion of Taiwan. The infiltration was focused on communications infrastructure in Guam and other parts of the U.S., the Times reported, and was particularly alarming to U.S. "is the champion of hacking." The spokesperson also claimed that the report was part of a coordinated campaign from the Five Eyes intelligence-sharing alliance, which is made up of agencies from Australia, Canada, New Zealand, the U.K. In a briefing Thursday in Beijing, a spokesperson for China's Ministry of Foreign Affairs dismissed the report and advisories as "filled with disinformation," and asserted that the U.S. intelligence agencies became aware of the incursion in February, around the same time that a Chinese spy balloon was downed, The New York Times reported. In the advisory, Microsoft urged impacted customers to "close or change credentials for all compromised accounts." The National Security Agency put out a bulletin Wednesday, detailing how the hack works and how cybersecurity teams should respond.
