There are two things I wish True Image supported: the aforementioned multiple destinations beyond the proprietary cloud adjunct, and non-proprietary container formats such as ISO, VHD, or even Zip. The main program, which admittedly you’ll rarely need to run, is also rather slow to boot-no doubt because it is checking your account/update status and the state of True Image’s various functions. The download is a whopping 600MB, the installation about the same, and there are six separate background processes running at all times. ![]() If all those features sound like they will use a significant amount of system resources, you’re correct. True Image has a number of auxiliary tools that are very useful. True Image supports restoring to different hardware (bare metal restore), though that’s generally become far less of an issue with Windows 10’s more robust driver functionality and infrastructure. Add to that the ability to create a restore partition, and Try & Decide, which is something like creating a restore point before you install new software, allowing you to roll back to the pre-install state easily. There’s also a clean-up utility that erases histories and securely wipes the free space on your hard drive. The latter two features are available only with the Premium version. The Standard version includes Active Protection, which wards off ransomware, as well as crypto-mining of your data. The tangential but still-interesting features include security: 256-bit AES encryption, block-chain file verification via Acronis Notary, and electronic signatures with the company’s Asign. Tape isn’t supported, but I’m guessing there aren’t a lot of people left who use that storage type. You can back up to just about any kind of media or location, including removable, optical, and FTP. Our enhanced defense will now automatically detect and stop cryptojackers, ensuring the integrity and performance of our customer’s machines.There’s also syncing with other PCs running True Image. ![]() With Acronis True Image 2019 Cyber Protection, we have expanded the heuristics of Acronis Active Protection – our AI-powered anti-ransomware defense – to detect and stop illicit cryptomining. The malware slows your computer’s performance, increases your electricity energy costs due to the additional workload on your computer, and it opens your system up to other malware strains like ransomware that are frequently bundled with the mining malware. While it might not seem dangerous at first, illicit cryptomining can actually create a lot of problems. By infecting Windows and Linux machines, cryptomining malware hijacks computing resources to conduct the calculations needed to create new cryptocoins. Usually that requires serious investments in computing power, electricity, and even cooling technologies so computers can work efficiently.īut what if you could complete the calculation without investing in those resources? That’s the question cybercriminals asked, and soon a new threat started appearing – illicit cryptomining. Legitimate cryptomining is a critical part of creating units of cryptocurrency – and as part of the process, the first person to solve the mathematical problem gets the new coin. Cryptocurrencies exist because people complete mathematical calculations that verify each transaction, which is called cryptomining. During the second half of 2017, there was a tremendous boom of interest in – and value of – cybercurrencies like Bitcoin. We take data recovery seriously – and personally.Īmong the new threats to user data is the explosion of cryptomining malware. That’s why we stand behind our recoveries 24/7. Our hardware testing lab is constantly expanding to reflect both industry progress and customer behavior.Īs a company, our mission is to protect all data, no matter where it lives. That means we put our solutions under twice as many QA checks as any other vendor, and extensively test on as many hardware configurations as possible, including PCs, Macs, laptops, external devices, NAS. That’s why we continually test, innovate, and support our software in ways no competitor can match. ![]() How can we say that it is the most reliable? Because after 15 years of protecting data, apps and systems, we know what it takes to keep your info safe. Named Acronis True Image 2019 Cyber Protection, the latest update to our award-winning personal backup solution introduces more than 150 individual enhancements-all designed to make this our most reliable offering ever. ![]() The stark difference in performance translates into a large cost differential as well. However, as you’ll see, if you have a more traditional client-server data-collection architecture, or one using a more common streaming pipeline with database consumers, like Apache Kafka, TimescaleDB can import more than three million metrics per second from one client-and doesn’t need 33,000 clients.īecause performance benchmarking is complex, we share the details of our setup, configurations, and workload patterns later in this post, as well as instructions on how to reproduce them. If you have an edge-based IoT system that pre-computes metrics on thousands of edge nodes before sending them, Amazon Timestream could simplify your data collection architecture. It’s certainly impressive to support 33,000 connections per second without issue, and this demonstrates one of the key advantages that Amazon presents with a serverless architecture like Timestream. To achieve three billion metrics/hour in their test, four million hosts sent 26 metrics every two minutes, an average of 33,000 hosts reporting 866,667 metrics every second. Just look at all of the databases we created through the process!Īfter all of our attempts to achieve better Amazon Timestream performance, we were even more confused when we read a recent post on the AWS Database Blog that discusses achieving ingest speeds of three billion metrics/hour.Īlthough the details of how they ingested this scale of data aren’t completely clear, it appears that each “monitored host” sent individual metrics at various intervals directly to Amazon Timestream. We REALLY tried to get Amazon Timestream to perform better. Although feedback was hard to find, we weren’t the only ones seeing these performance results, as evidenced by a similar benchmark by Crate.io. We even posted on Reddit to see if others had been able to get better performance with Amazon Timestream. These results were so dramatic that we did not believe them at first, and we tried a variety of workloads and settings to ensure we weren’t missing anything. Note: Several queries’ ratios (high-cpu-all, lastpoint, groupby-orderby-limit) are “undefined” because Amazon Timestream did not finish executing them within the default 60-second timeout period that Timestream imposes, while TimescaleDB completed them in less than a single second Results of benchmarking query performance between TimescaleDB and Amazon Timestream ![]() In particular, there were workloads and query types easily supported by TimescaleDB that Amazon Timestream was unable to handle. TimescaleDB outperformed Amazon Timestream 6,000x on inserts and 5-175x on queries, depending on the query type. ![]() For those interested, we go into much more detail later in this post. We compare TimescaleDB and Amazon Timestream across several dimensions:īelow is a summary of our results. Amazon Timestream customers include Autodesk, PubNub, and Trimble. Amazon Timestream not only shares a similar name to TimescaleDB, but also embraces SQL as its query language. This is Amazon’s time-series database-as-a-service. The TimescaleDB community has become the largest developer community for time-series data: tens of millions of downloads over 500,000 active databases organizations like AppDynamics, Bosch, Cisco, Comcast, Credit Suisse, DigitalOcean, Dow Chemical, Electronic Arts, Fujitsu, IBM, Microsoft, Rackspace, Schneider Electric, Samsung, Siemens, Uber, Walmart, Warner Music, WebEx, and thousands of others (all in addition to the PostgreSQL community and ecosystem).Īmazon Timestream was first announced at AWS re:Invent November 2018, but its launch was delayed until September 2020. TimescaleDB, first launched in April 2017, is today the industry-leading relational database for time-series, open-source, engineered on top of PostgreSQL, and offered via download or as a fully managed service on AWS. ![]() But if you let the analysis speak for itself, you’ll find that we stay as objective as possible and aim to be fair to Amazon Timestream in our testing and results reporting.Īlso, if you want to check our work or run your own analysis, we provide all our testing via the Time-Series Benchmark Suite, an open-source project that anyone can use and contribute to. Yes, we are the developers of TimescaleDB, so you might quickly disregard our comparison as biased. This post compares TimescaleDB and Amazon Timestream across quantitative and qualitative dimensions. ![]() ![]() While no specific details on the project have been made available by CD Projekt Red, a graphical overhaul and improved performance for console players is likely.

Colored lighting bounces realistically across the scene and onto characters, the warm glow of the sun is replicated across surfaces rather than just in the sky, and in general scenes appear as you would expect them to in reality. Combined with the updated time of day weather conditions, players will now experience a much more realistic image when exploring the massive world of The Witcher 3: Wild Hunt. RTXGI is utilized in all gameplay and cutscenes, and is truly transformative. Recreating this effect in games requires ray tracing, and with the addition of NVIDIA RTX Global Illumination (RTXGI), the realistic properties of light can be accurately simulated with our highly performant technique (a lower-precision implementation of RTXGI is also available in the next-gen console edition of The Witcher 3: Wild Hunt). Furthermore, the color properties of surfaces are absorbed and added to bounces, so for example, bright light bounced from a red wall to a white tiled floor would feature a tinge of red. In reality, sunlight bounces, increasing the illumination of nearby surfaces and objects. And so much more, which you can read about in full in the patch notes.Īll of this is best experienced on GeForce RTX systems, thanks to our performance-accelerating Ray Tracing Cores, and DLSS, our best-in-class AI-powered super resolution technology.

Holmes and colleagues 1 have proposed that by completing a demanding visuospatial task during memory consolidation or reconsolidation for a traumatic event, the memory trace is weakened because of competition for the cognitive resources required for consolidation. 8 During this reconsolidation process, the memory trace is also vulnerable to interference. 7 In addition, it has been proposed that following reactivation, a memory again enters a labile state and must be reconsolidated into long-term memory. 6 Performing an unrelated task while the memory for an event is in a labile state can reduce subsequent retrieval. 5 Shortly after the event, the memory trace remains in a labile state as it is consolidated, and it is susceptible or vulnerable to interference. 2 – 4įollowing exposure to an event, the memory trace of that event must be consolidated into long-term memory for it to be accessible for later recall. ![]() 1 – 3 Holmes and colleagues have shown that playing Tetris directly after trauma exposure can reduce subsequent intrusive memories of the traumatic event, and they have demonstrated the efficacy of this “cognitive vaccine” in both experimental 1 and real-world settings.

The whole team at Mile High Spirits is praying for the victim’s quick recovery, and he’s welcome at Mile High Spirits to enjoy complimentary drinks forever.A dancing FBI agent who accidentally shot a man in the leg after doing a backflip at a Denver bar will avoid jail time after pleading guilty Friday to third-degree assault.Ĭhase Bishop, 30, struck a plea deal with prosecutors and was sentenced to two years of probation, The Denver Post reported. They finished the statement by saying that they hope the dude gets better soon and that he will be comped for drinks for life, which seems more like something the FBI should be paying for: As a result of his misconduct, one of our innocent patrons was shot. It is shocking that the only shooting to ever occur at our establishment came about as a result of an FBI agent entering our distillery tasting room carrying a loaded firearm without our knowledge, in violation of our rules. Mile High Spirits, the distillery and tasting room at which the shooting happened, released an absolutely surreal statement that neatly transitions from talking about the quality of their product to being like ‘oh hey, an FBI agent brought a fucking gun onto the d-floor’:Īt Mile High Spirits, we pride ourselves on being a craft distillery with high-quality products and an engaging customer experience, in a fun and safe atmosphere. “He was like ‘I’m all good,’ as they were loading him in the ambulance.” The dude who got shot took it pretty well, she said: “The guy he shot was directly in front of him, about 10-15 feet away. But she didn’t see him check on the man he shot. It took a few moments for anyone to realize someone had been hit by the bullet.Ĭhancellor says that the appearance of Bishop just walking off and not checking on the victim was pretty true of the situation:Ĭhancellor says she was focused on the man who was shot and her eyes didn’t follow the man with the gun. “He pulled the trigger when he grabbed it and we see this flash…It sounded like a firecracker.”Ĭhancellor said the DJ stopped the music for a moment to ask if everyone was okay then started it up again. “Everyone was like, ‘Holy s***, is that a gun?’” she said.

This agent was dancing at a Denver bar on Saturday night. The man, identified by CBS News as FBI agent Chase Bishop, was caught on video dancing his little pants off, doing a backflip, scrambling to pick up the gun that flew out of his pants before doing ‘my bad’ hands and walking off because he accidentally fired the weapon into a person. This might seem like common sense to some people, but I think it might have come in handy if I had told it to the FBI agent who accidentally shot a patron at a bar in Denver, Colorado on Saturday night. If you absolutely insist on doing all of those things, I would thoroughly recommend that you don’t a) have the gun tucked into the waistband of your pants and b) do a backflip in a crowded bar. If you simply must do both of those, I would recommend that you at least don’t have the safety off on that gun. If you do, I would suggest that you maybe avoid having a round in the chamber of that gun. If I was forced to give any advice on the issue, I would say that – at the very minimum – you should probably not do the following: have a gun on you when you’re drunk. ![]() 1920x1224px Anime, Yuri!!! on Ice, Yuri!!! on ICE, Yuuri Katsuki, HD wallpaper.1378x2039px anime, Yuri on Ice, portrait display, Russia, HD phone wallpaper.2436x1150px Anime, Yuri!!! on Ice, Viktor Nikiforov, Yuri!!! on ICE, Yuuri Katsuki, HD wallpaper.1920x1080px Anime, Yuri!!! on Ice, Viktor Nikiforov, Yuuri Katsuki, HD wallpaper.1920x1080px Anime, Yuri!!! on Ice, Viktor Nikiforov, Yuri!!! on ICE, Yuuri Katsuki, HD wallpaper.1080x1920px anime ahegao, hentai, fondo, manga, anime manga, HD phone wallpaper.3779x2551px Anime, Yuri!!! on Ice, Viktor Nikiforov, Yuuri Katsuki, HD wallpaper.3840x2400px ice skating, ice stadium, white women's ice skates, ice, HD wallpaper.1802x2421px victor nikiforov, yuri on ice, artwork, shoujo, anime boys, Anime, HD phone wallpaper.2300x1652px Anime, Yuri!!! on Ice, Yuri!!! on ICE, Yuuri Katsuki, HD wallpaper.1939x1355px Anime, Yuri!!! on Ice, Viktor Nikiforov, Yuuri Katsuki, HD wallpaper.1920x1200px Anime, Yuri!!! on Ice, Yuri!!! on ICE, Yuuri Katsuki, HD wallpaper.1133x2644px Ahegao, anime, manga, HD phone wallpaper. ![]()

Includes wires to connect gauges, indicator lights, and switches to their proper sources. In this article, we’ll be providing an overview of the wiring color codes for 1979 El Camino rear lights and how they can help you understand the wiring system in your car.įirst, let’s take a look at why understanding the wiring color codes is so important. ![]() Are you looking for information about wiring color codes for 1979 El Camino rear lights? If so, then you’ve come to the right place. Thus melting points vary with lattice energies for ionic substances that have similar structures. At the melting point, the ions can move freely, and the substance becomes a liquid. The melting point The temperature at which the individual ions in a lattice or the individual molecules in a covalent compound have enough kinetic energy to overcome the attractive forces that hold them together in the solid., for example, is the temperature at which the individual ions have enough kinetic energy to overcome the attractive forces that hold them in place. The magnitude of the forces that hold an ionic substance together has a dramatic effect on many of its properties. The Relationship between Lattice Energies and Physical Properties The order of increasing lattice energy is RbCl ZnS > SrSe > LiCl > KBr Because the cation and the anion in BaS are both larger than the corresponding ions in CaO, the internuclear distance is greater in BaS and its lattice energy will be lower than that of CaO. Because Ba 2+ lies below Ca 2+ in the periodic table, Ba 2+ is larger than Ca 2+. To decide whether BaS or CaO has the greater lattice energy, we need to consider the relative sizes of the ions because both compounds contain a +2 metal ion and a −2 chalcogenide ion. Consequently, we expect RbCl, with a (−1)(+1) term in the numerator, to have the lowest lattice energy, and GaP, with a (+3)(−3) term, the highest. We know from Equation 8.4 that lattice energy is directly proportional to the product of the ionic charges. The compound GaP, which is used in semiconductor electronics, contains Ga 3+ and P 3− ions the compound BaS contains Ba 2+ and S 2− ions the compound CaO contains Ca 2+ and O 2− ions and the compound RbCl has Rb + and Cl − ions. For compounds with ions with the same charge, use the relative sizes of the ions to make this prediction. Using Equation 8.4, predict the order of the lattice energies based on the charges on the ions. A similar effect is seen when the anion becomes larger in a series of compounds with the same cation.Īrrange GaP, BaS, CaO, and RbCl in order of increasing lattice energy.Īsked for: order of increasing lattice energy Because r 0 in Equation 8.4 is the sum of the ionic radii of the cation and the anion ( r 0 = r + + r −), r 0 increases as the cation becomes larger in the series, so the magnitude of U decreases. This effect is illustrated in Figure 8.2 "A Plot of Lattice Energy versus the Identity of the Halide for the Lithium, Sodium, and Potassium Halides", which shows that lattice energy decreases for the series LiX, NaX, and KX as the radius of X − increases. For example, the calculated value of U for NaF is 910 kJ/mol, whereas U for MgO (containing Mg 2+ and O 2− ions) is 3795 kJ/mol.īecause lattice energy is inversely related to the internuclear distance, it is also inversely proportional to the size of the ions. Source: Data from CRC Handbook of Chemistry and Physics (2004).īecause the lattice energy depends on the product of the charges of the ions, a salt having a metal cation with a +2 charge (M 2+) and a nonmetal anion with a −2 charge (X 2−) will have a lattice energy four times greater than one with M + and X −, assuming the ions are of comparable size (and have similar internuclear distances). Note that r 0 may differ between the gas-phase dimer and the lattice. In such an arrangement each cation in the lattice is surrounded by more than one anion (typically four, six, or eight) and vice versa, so it is more stable than a system consisting of separate pairs of ions, in which there is only one cation–anion interaction in each pair. While Equation 8.1 has demonstrated that the formation of ion pairs from isolated ions releases large amounts of energy, even more energy is released when these ion pairs condense to form an ordered three-dimensional array ( Figure 7.8 "Definition of Ionic Radius"). These properties result from the regular arrangement of the ions in the crystalline lattice and from the strong electrostatic attractive forces between ions with opposite charges. They are not easily deformed, and they melt at relatively high temperatures. ![]() Ionic compounds are usually rigid, brittle, crystalline substances with flat surfaces that intersect at characteristic angles. ![]() Recall from Chapter 2 "Molecules, Ions, and Chemical Formulas" that the reaction of a metal with a nonmetal usually produces an ionic compound that is, electrons are transferred from the metal (the reductant) to the nonmetal (the oxidant).
