![]() ![]() The high density altitude, flying over Colorado mountains in August, meant that in the turn, the plane was as high as it was capable of flying and was no longer able to climb at speed. The altitude, temperature and humidity combined to create the density altitude of 13,000 feet when the aircraft was actually at 10,200 feet. The plane lost lift and the stall warners sounded. The pilot presumably panicked because he then compounded his worsening situation with the steep turn to the right. He saw the ski slopes which are almost certainly on the leeward side of the mountain: mountain flyers know these can produce a severe downdraft and are trained not to fly straight into them. The pilot continued to fly into rising terrain until he was boxed in. The density altitude was about 13,000 ft. ![]() the airplane subsequently stalled, flipped over, and entered the trees. The pilot made a 60-deg bank, and the stall warning horn could be heard 3 times during aprx 180 deg of turn. During the last few seconds of the tape, the terrain dominated the view through the cockpit window. Comparing the recording to a topographical map, the flight was climbing and its altitude above the ground was decreasing when it crashed at the 10,200-ft level. Video tape recovered from the wreckage provided a visual and audio record of the flight from takeoff to impact. On 8/23/87, it was found on the slope of a high tree-covered ridge. ![]() The airplane departed Grandby 8/10/84 and failed to arrive at its destination. Using the video as primary source data, the NTSB released an accident report. The video was released to the FAA who who were amazed to find that it had survived both the crash and three years of exposure with only minor damage. The wreckage was discovered three years later, when backpackers hiking through the woods found the crash site, including a video tape hanging from tree branches. Although there was a fire, it burnt out quickly and there was not enough damage to mark the crash site from the air. No one knew what had happened: the aircraft had tumbled into the trees and landed on the Emergency Locator Transmitter, cutting off the signal. The tandem plane departed Granby (KGNB) with a passenger for the scenic flight over the Colorado mountains but never arrived at Jeffco (KBJC) as planned. The pilot started the camera shortly after takeoff and it ran until the aircraft crashed down through the trees – approx. One thing that was unique about this particular flight was that the pilot had mounted a VHS video camcorder atop the instrument panel for the purpose of visually recording any beetle infestation that was observed along the flight route. of Forestry to videotape a particularly nasty type of beetle infestation that had been ravaging hundreds of acres of Colorado forest in and around some of the higher-elevation foothills surrounding some of the Rockies. had been offered a contract by the Colorado Dept. It was a Cessna L-19E “Bird Dog” – a two-seater liaison and observation aircraft built for the US Military. The lights further allows aircraft identification in flight, and some lights also help the pilots to navigate the aircraft on the ground and help to view certain structures of the aircraft.The plane went missing on the 10th of August in 1984. The video shows lights which are required for safety purposes and are used to alert the personnel working around the aircraft in low light hours. The video left netizens stunned with the breathtaking view as the aircraft was about to land at an airport at night. The sight at night from window seats leaves passengers mesmerised, but have you ever wondered if a cityscape from a window seat can amaze travellers, then how beautiful can a view from the cockpit be? A video recently took over the internet by storm showing the night landing from a Boeing 777 plane. Flight journeys not only make you reach your destination in a short span of time but also give you the best views from ‘Cloud 9.’ In order to get the best views from a plane, one should choose the window seat as it is more private, and gives you the perfect shot for your Instagram story.

Usually that’s enough time for the script to finish running, so it’s not an issue for us, but it is something to be aware of.Īs with most of my scripts, this is written in Python. Our queue-backed workers scale down to zero when the queue is empty, and they take a few minutes to start up when the queue starts filling. The messages would bounce back-and-forth forever. The script would then resend them to the input queue, and the worker would send them back to the DLQ. It uses code I shared two years ago to dump the contents of an SQS queue.īe careful running this code – if the worker is running, and it picks up the messages immediately, they might go back to the DLQ if there’s another problem with the worker. Although we primarily use this to redrive problematic messages that went to a DLQ, this script allows you to move messages between an arbitrary pair of SQS queues. There’s no way to do this in SQS directly, so we’ve written a script to do it for us. Once we’ve found the problem in the worker, fixed the bug and deployed a new version, we want to send all the messages from the DLQ back to the original input queue, so they can be processed by the updated worker. You can configure SQS to send such problematic messages to a dead-letter queue (DLQ), where you can inspect them in isolation and work out what went wrong. Sometimes a task can’t be processed successfully – for example, if there’s a bug in the worker code. To address this, we explore a custom solution rather than relying on the built-in SQS redrive feature. Boxes, L–R: a pink box (labelled “input queue”) a black dashed box (labelled “worker”) another pink box (labelled “output queue”). While AWS Lambda functions have a maximum runtime of 15 minutes, orchestrating an action after precisely 6 hours poses a challenge. worker input queue output queue Three boxes joined by arrows, pointing from left to right. When the worker is done, it sends the message to another queue, where another worker can pick it up. We write tasks to an SQS queue, and then a worker application reads the tasks from the queue and does some processing. If other arguments are provided on the command line, those values will override the. The JSON string follows the format provided by -generate-cli-skeleton. This error occurs when the DLQ redrive fails because the AWS Identity and Access Management (IAM) entity doesn't have the required permissions.At work, we make heavy use of Amazon SQS for message queues. -cli-input-json-cli-input-yaml (string) Reads arguments from the JSON string provided. Error code: AccessDenied - Queue Permissions to Redrive" error This error occurs when the DLQ redrive fails because the Amazon SQS source queue doesn't exist or was deleted.

A message from the Amazon Simple Notification Service (Amazon SNS) topic or AWS Lambda function that has the DLQ configured.An Amazon SQS message that's sent with the SendMessage API call to the DLQ.If the DLQ has one of these messages, then you might receive this error when you try to start a DLQ redrive to the source queue: It also helps if the function fails to process an event from the corresponding SQS FIFO queue multiple times. ![]() ![]() This is useful in case SNS cannot deliver an event to the subscribed SQS queue.

For example, a p-series with n>1, or a geometric series with |r|1).įor example: S = Σ(n=1 to infinity)((n+1)/(n³+6n+3)).ġ) The dominant term of the denominator (n³) is larger than the dominant term of the numerator (n), so my intuition says that S should converge.Ģ) a) Since I am dealing with rational functions (ratios of polynomials), a p-series with n>1 would make a good S'. However, I do have a recipe to approach the proof of a series’ convergence/divergence with the limit comparison test.ġ) I start with an intuition: does S looks like is converges or diverges? Let’s say it looks like it converges.Ģ) Then I look for another series S' such that:Ī) I know that S' converges. Oresme’s proof is very witty and I believe finding such proofs requires patience, serendipity, creativity and mathematical experience. I suggest you do a search on the convergence of 1/n² to get more background so you can feel confident in your own mind why this is so. There are several proofs, one using the integral test, another uses the Cauchy Condensation test. In a similar manner, the terms add so little to the sum that they do not impact the total. Do you see how we can keep doing this process infinitely many times and NEVER get to b. ![]() Now to get to b you need to go half way from a' to b. To get to point b you first need to go half the distance from a to b. That is, each term in 1/n² decreases at a sufficiently fast rate that even though you continue to add to the sum, what you are adding is so infinitesimally small that it makes no difference to the final sum. The reason that 1/n² converges has to do with how fast each term is getting smaller. Was just a very simple simulation, here is the code in R:įirst, the series 1/n and 1/² both have the same number of terms, an infinite number. This seems to indicate the series is diverging (if it were lowering I'd say it would eventually converge). This increase by 2.3 per order of magnitude does change very minimally in a positive as opposed to a negative direction. The increase here has gone up to 2.3.Īs the order of magnitude increase approaches very large numbers (I ran a simulation going to 9 orders of magnitude, a steady increase of 2.3 is noticed. However, if we take 100,000 terms, we end up with approximately 12.09, compare this to one order of magnitude less, which is only 10,000 terms and we end up with approximately 9.79. The difference between these two numbers is about 2.26. If we take 100 terms, we end up with 5.19. Interestingly I noticed that for each increase in order of magnitude of the number of terms, the sum of the series increases by approximately 2.3, however this number seems to increase rather than decrease, indicating a non-convergence.įor example, say we take 10 terms, we end up with approximately 2.92. Hank, your observation spurred me to find an answer myself, so I ran some simulations. ![]() And that they're balanced by being able to dodge them should a ship maintain sufficient range from torpedo armed boats, as well as a bit of a clever tactical planning for them being inevitably launched at such a tempting target. Those who say torpedoes are fine, point out that torpedoes are supposed to be dangerous threats, and historically were to battleships. Those asking for a Nerf typically point out the high base damage combined with the extremely high chance of even a single hit causing the Flooding Damage Over Time effect. Torpedoes have caused some debates over how strong they are, pitting those who primarily captain Battleships, versus those who use Destroyers and Carriers with Torpedo Bombers.As the years have passed, Carriers have only become more hated. The majority of the playerbase simply aren't interested in playing carriers in a game that is meant to be about gun warships. From the moment carriers were introduced the fandom is split between people who hate CV's and CV mains.The approach seems to be mostly praised by Wows's own fandom, though there are its detractors. ![]() The Warships team responded by greatly simplifying a lot of mechanics from 'Tanks,'' like the commander/ crew system.

Tired of the usual Thumbs Up designs? Make your ow n ascii thumbs up symbol by inputting ASCII character codes. Tap it if you like the video you watched, or tap the Thumbs Down emoji, beside the Thumbs Up emoji if you dislike it. On YouTube, you don’t even have to learn how to make a thumbs up on the app, because the YouTube thumbs up icon is already there, below every single video. As you compose your email in Outlook, just select and copy the smiley-face icon from the mail client’s toolbar. At the same time, on Instagram, thumbs up i nsertion is achieved by using a built-in emoji keyboard, a staple feature on both iPhone and Android devices.Ī similar process is applied to access the thumbs up emoji on Outlook. Meanwhile, if you’re using Windows Live Messenger, the letter Y is all that’s needed to make the officia l thumbs up MSN emoticon appear. You can even make a thumbs up symbol from your keyboard, just press the alt key and type the thumbs up keyboard shortcut 128077 on your keypad. It’s not unusual to see a thumbs up in text messages, online chats, and social media feeds. Second, it’s compatible with almost every major operating system and platform. The two major reasons why the Thumbs Up emoji is so popular are that it’s pretty self-explanatory and can be used in so many situations. If you’re a parent, and you need to give permission to your kids, or are you in a hurry but need to reply to something important? Share the thumbs-up sign to express “Okay” or “Cool.” How To Use Thumbs Up Emoji On Different Platforms Give a big thumbs up if someone you’re talking to has a recent achievement, and you want to say, “Oh, that’s great,” to him or her. For the latter is most likely due to the high degree of similarity it has with the Facebook Like button. Meanwhile, other users prefer to call it the “Yes emoji” or “Like emoji. If you see the yup emoji online, it’s most likely another name for Thumbs Up. In some instances, the Thumbs Up emoji may sometimes go by a different name. ASCII-painted pics have become so popular, chances are, you’ve already seen a thumbs up ascii online somewhere on the Internet, but didn’t know that’s what it’s called. ![]() ASCII art, also called keyboard art, or text art, creates pictures out of text symbols. But if you’d like your emoji to stand out, you can always create your own Thumbs Up emote with ASCII art. This simple yet effective thumb symbol is also almost identical across all platforms. Consider this: instead of typing the words “I agree” or “good job,” users can simply share the emoji thumbs up to convey their message. It is one of the most popular emojis in the world because it is quite practical and convenient to use. It is used to express understanding, recognition, encouragement or approval. Express praise or approval with a thumbs up! The Thumbs Up emoji displays the famous thumbs-up gesture, a common movement of the hand achieved by a closed fist held with the thumb. ![]() So, these entries would add variables for all members of the sudo group. #Defaults:%sudo env_keep += "GPG_AGENT_INFO" ![]() In other words, the next time sudo is run a password will be required.

Here's what the sudo man page has to say about this option: -k, -reset-timestamp. If the -l option was specified without a command, sudo will exit with a value of 0 if the user is allowed to run sudo and they authenticated successfully (as required by the security policy). The sudo command offers a lot of options that influence how it behaves, although it's commonly used in its most basic form, with no options. #Defaults:%sudo env_keep += "SSH_AGENT_PID SSH_AUTH_SOCK" Thankfully, there exists a command-line option -k that allows users to revoke sudo permission. # "sudo scp" or "sudo rsync" should be able to use your SSH agent. #Defaults:%sudo env_keep += "EMAIL DEBEMAIL DEBFULLNAME" # Per-user preferences root won't have sensible values for them. #Defaults:%sudo env_keep += "GIT_AUTHOR_* GIT_COMMITTER_*" As an example, let’s check the commented-out tips which come with the default sudo policy module: # While you shouldn't normally run git as root, you need to with etckeeper Let’s notice that env_keep is located in the Defaults entry of the sudoers file. Consequently, we can grant variable access in a fine-grained way. Then, we can compose separate env_keep for users, hosts, commands, and target users. So, each variable enrolled is passed to the sudo environment. In detail, we can regard this option as a list. Now let’s use the env_keep option in the sudoers file to manage variables’ visibility. |
