To see how Paragon Backup and Recovery performs against other data recovery software, read our Best data recovery software buying guide. Note that Paragon also does Hard Disk manager. The downside is that OnTrack costs significantly more than using Paragon or CrashPlan ahead of time. Whereas Paragon and CrashPlan act as preventative measures by creating backup copies of your data, OnTrack can help you recover data when there’s no backup available. If you do need the ability to recover deleted files or pull data from a broken hard drive, check out OnTrack EasyRecovery. While it won’t help you boot a crashed operating system, CrashPlan does offer much more control over file versioning than Backup and Recovery. CrashPlan, which enables you to back up an unlimited amount of data to the cloud, physical hard drives, or both, costs just $10 per computer per month. Paragon Backup and Recovery: The competitionĪt the end of the day, Paragon is competing more with other free and affordable backup tools than with true data recovery solutions. On the other hand, some users may prefer to pay for a premium service that offers cloud storage and other critical functions. You can also use Paragon to prepare a WinPE bootable environment as an ISO image or through a USB drive, making it easy to recover data after experiencing problems with your operating system.Īdditionally, Paragon Backup and Recovery is extremely easy to use and accessible to people who aren’t familiar with the process of backing up files. That said, it contains most of the tools you need to store data and consistently update your backups, and it outperforms many other free hard drive recovery programs. Paragon Backup and Recovery is missing a few key features, including online backups and an active support forum. Paragon Backup and Recovery: Final verdict Finally, registered users can submit tickets directly to Paragon for one-on-one support. While there’s a dedicated support forum, it’s no longer active. This all-in-one software contains every hard disk management tool to meet the needs of PC users seeking to keep their vital digital data safe and effectively maintained in physical or virtual environments, including full functionality for partitioning, backup and recovery, copy and migration, security and optimization, boot management, and virtu. (Image credit: Paragon Software)įurthermore, the Paragon blog offers long-form articles covering different functions and tips for using the platform. The Knowledge Base offers answers to some of the most common questions. The automatic backup tool enables you to copy an entire disk or just specific files. With Backup and Recovery, it’s easy to manage your data at a glance and create a consistent backup schedule. Once the data is backed up, Backup and Recovery makes it simple to import it back to the original location. We didn’t encounter any major performance issues while using the application, but the backup took slightly longer than expected. Unfortunately, Mac users can currently only access the program on macOS 10.15. Paragon Backup and Recovery has relatively low system requirements and should work well on any computer running Windows 7 or newer, although it’s worth noting that as Windows 7 is no longer supported by Microsoft, you probably should have upgraded your OS by now. Regular backups help avoid the need to recover lost or corrupted files as other versions of your files are kept safely elsewhere. It’s easy to set up a bootable USB drive as Backup and Recovery walks you through each step of the process.

Legacy Autosport has also purchased a car and stated its intent to compete in Indy Lights.Īltogether, the year-to-year growth should be remarkable. Force Indy is also expected to continue, but it’s unclear whether that will remain as a standalone entry or if it will count as one of HMD’s eight. Juncos Hollinger Racing is aiming to field two along with USF2000 champion Cape Motorsports, which will step up to Lights. Andretti Autosport is set to return with four, and from there, Abel Motorsports is expected to continue with two cars. The HMD Motorsports with Dale Coyne Racing team will expand to run eight cars next year. And I’m sure that Andretti and HMD and everybody else that’s going to continue to invest in Lights is going to be happy next year. “It’s going to be a great year, and I’m thrilled with it. We’ll have Firestone coming in to supply tires next year, so it’ll be a consistent tire between Indy Lights and the Ind圜ar side of it. We’ve stepped up the technical side of it. And I think Levi’s done an outstanding job. “When you think about it, we could have 15 to 18 cars next year and good teams coming in, leaving other series, and coming into the Lights series. “Since we’ve taken it over, there’s no question that the interest is just amazing,” Penske told RACER. In most regards, Penske’s debut as promotor for the series was a success. Enhancements in the return of prize money for each race and a new deal to bring Firestone back to Indy Lights as its sole supplier were announced under Penske’s watch. With its purchase of Ind圜ar in 2020, Penske Entertainment targeted taking over the Indy Lights property that came with the sale, and after Andersen Promotions completed the 2021 season, full control returned to Indy Lights’ parent company. The chassis and unbadged motor continue to serve as the basis of the Indy Lights series. The success follows the groundwork established by Dan Andersen and his daughter Michelle Kish, who operated the championship for eight seasons.Īfter a series of failures to modernize the Lights series, Ind圜ar handed control of the series to Andersen Promotions in 2014, and by 2015, a new Dallara IL15 chassis and turbocharged four-cylinder Mazda engine was introduced to help the top step of the Road To Indy move forward. The prospects for 2023 are especially encouraging, with an anticipated spike in entries that could push Indy Lights to nearly 20 cars for the first time since the 2000s. Of the notable changes, a new series boss was installed with Levi Jones, investments were made in the hardware used to perform technical inspections, and a slight increase in grid size with 12 full-time entries and fields that reached 14 cars at a handful of rounds were recorded Roger Penske is proud of the job his Penske Entertainment team have done during their first season of running the Indy Lights championship. I expect this sort of behavior from a shady used car dealership, but not an official Mazda dealership. He refused to do anything about it and then kicked me out of his office. The tires on the car are rated for 65,000 miles, these have barely lasted to 20k. According to any tire dealer, 4/32 is the time that you start looking for new tires.

The genomic sequencing classifier had a sensitivity of 91% (95% CI, 79-98) and a specificity of 68% (95% CI, 60-76). Results Of the 183 included patients, 142 (77.6%) were women, and the mean (range) age was 51.7 (22.0-85.0) years. The secondary end point was measurement of classifier performance in biopsies from Bethesda II, V, and VI nodules. Main Outcomes and Measures The primary end point was measurement of genomic sequencing classifier sensitivity, specificity, and negative and positive predictive values in biopsies from Bethesda III and IV nodules. Algorithm development and independent validation occurred between August 2016 and May 2017.Įxposures Thyroid nodule surgical histopathology diagnosis by an expert panel blinded to all genomic data. Of these, 191 samples (91.0%) had adequate residual RNA for validation of the genomic sequencing classifier. There were 210 potentially eligible thyroid biopsy samples with Bethesda III or IV indeterminate cytopathology that constituted a cohort previously used to validate the gene expression classifier. All patients underwent surgery without genomic information and were assigned a histopathology diagnosis by an expert panel blinded to all genomic information. Objective To measure the performance of a genomic sequencing classifier for cytologically indeterminate thyroid nodules.ĭesign, Setting, and Participants A blinded validation study was conducted on a set of cytologically indeterminate thyroid nodules collected by fine-needle aspiration biopsy between June 2009 and December 2010 from 49 academic and community centers in the United States.

This theory is supported by the numerous references to cryogenics and life extension that come up in the movie. David opted for a lucid dreaming cryogenic slumber. With those major alternative theories out of the way, this leaves only the ending as explained by Tech Support. With the joke easily explained as a red herring. But there are close to a dozen references of cryogenics and life extension. There’s only a brief joke about him being in a coma that happens halfway through the movie. Like, if this theory were true then we should have gotten something like “he asks what date it was and it’s still 2001 rather than 2151.” As is, we have no legitimate reason to not believe the lucid dream/cryogenics theory isn’t true. Especially to then not show that with the last shot. My only real reason against this is that it would be a HUGE ask of the audience to build up to this cryogenics/lucid dream climactic rooftop scene where we are told “what really happened” only for none of that to be true and him to have only been in a coma after the accident. He’d only have dreamed of the failed date at the club (how embarrassing that was) and all the fallout. Which means Sofia’s still alive and he would still have a chance with her. Maybe the accident sent him into a coma but his face isn’t as bad as he imagined? At the very least, 150 years probably wouldn’t have passed. That and David waking up as the final shot of the movie. Given the defeat of McCabe and him not continuing to question the lucid dream theory, it’s definitely a dream. Either that’s because David has lost his mind and is seeing things (which could be true) or it is a lucid dream. Also, all the other characters just appear on the rooftop, out of nowhere. Which leads me to believe that the board wasn’t developed because they were only a red herring to keep us guessing, rather than the true enemies. Normally you wouldn’t see a film completely disregard the main antagonists like that. Also, if it was the board trying to get rid of David then the board was woefully underdeveloped. That puts him clearly in the realm of being a superficial construct of David’s lucid dream. The first was semi-plausible up until the point that Tech Support asks McCabe what the name of his children are and McCabe can’t answer. Curtis McCabe tries arguing at the end, is trying to get rid of David in order to take over the companyĢ: David’s in a coma after the car crash and he’s just imagining everything. The alternative theories of the ending would be:ġ: This isn’t a dream.

They can be personalized with the dead person’s favorite food, mementos from their lives and their favorite items. The ofrendas (offerings), as the altars are called, are carefully assembled using many traditional elements, but each of them is unique on its own. The pungent scent and bright color of fresh marigold petals are meant to guide the spirits to their altars, and glasses of water are handy to quench the thirst of the dead after their long journey. Sugar skulls, candles, pan de muerto (dead man’s bread) and Mexican marigolds are featured throughout the altar. The different levels represent the underworld, Earth and heaven.Ī large photo of the deceased is usually placed at the very top of the altar with papel picado. The colorful multi-level memorials are built in homes, schools and public places as a tribute to deceased loved ones. This altar pays tribute to Mexican singer Juan Gabriel who died in 2016. The holiday is a time to celebrate the lives of friends, family members and even celebrities who have died. To decide whether the Game of Life can experience consciousness, we have to answer two philosophical questions that can’t be answered with math.ĭoes consciousness arise from heaps of parts, interacting according to rules? So far, everything I’ve said is mathematically proven. Here’s another big leap: can a pattern in the Game of Life experience consciousness? If you put the right symbols on its tape, it can play chess, it can forecast the weather, it can translate German to Chinese. This is a Turing machine, and it can compute anything that can be computed. All its power comes from how the squares are arranged at the beginning after that, the three rules determine how the machine behaves. Every square in this machine is following the three rules of survival, death, and birth. When the video zooms in, you can see that the machine is made of the basic patterns we saw before: still lifes, oscillators, and gliders. The long diagonal line is the tape, and the rectangle in the middle is the part that transitions between modes, and moves back and forth along the tape. It’s enormous, covering millions of squares. This pattern is a Turing machine, constructed in the Game of Life. This is a useful fact because we can compare any system (such as real computer) to Turing’s machine to see if they are equivalently capable.Ĭan the Game of Life compute anything a Turing machine can? Yes it can. For any reasonable definition you can think of, Turing’s claim is true. The term “computable” is unfortunately vague, but it means something like “a series of actions, following precise rules”. There’s been a century of intense research into this claim. Turing described his machine and claimed that anything which can be computed, could be computed by this simple machine. In fact, Turing never built one, the video above shows a hobbyist’s interpretation. The machine is so simple, you can prove theorems about it. (The tape is like its hard drive.) Additionally, the machine has a fixed number of modes (known as “states” in computer science), and it can transition from one mode to one other mode each time it reads a symbol from its tape. It can read, write, or alter one symbol at a time on any position on the tape. It has an infinitely long tape, which it can move forward or backward. In a 1936 paper, Alan Turing described an imaginary machine. The question everyone’s researching is, given how simple the game is, what can it do? What can Game of Life patterns do?Ĭan a pattern in the Game of Life do nothing? Soon some computer scientists made programs that can run large games fast, eventually simulating boards with billions of squares, playing thousands of steps per second. When Conway was first playing with the Game of Life, he did it by hand, trying configurations on a board for the game of Go. One day when he was lecturing on symmetry and the Platonic solids, he brought in a turnip as a prop, carved it one slice at a time into an icosahedron, with its 20 triangular faces, eating the scraps as he went. Conway gained a reputation for his high jinks (not to mention his disheveled appearance). Hired at Cambridge as an assistant lecturer, Dr. He could be easily distracted by what he called “nerdish delights.” He once built a water-powered computer, which he called Winnie (Water Initiated Nonchalantly Numerical Integrating Engine). Conway cultivated his acknowledged lifelong preference for being lazy, playing games and doing no work. The Times said his work “ranged from the rigorously highbrow to the frivolously fun, earning him prizes and a reputation as a creative, iconoclastic and even magical genius”.Īs a student, Dr. He was born in England in 1937 and spent most of his career at the University of Cambridge, and then at Princeton. I read his obituary in the New York Times, and learned what a delightful person he was. I studied some of his work in college, but hadn’t thought about him much until he died last year. John Conway’s not a computer scientist, but he’s well-known among programmers like me for the Game of Life and similar math research that veers into computer science. (It’s not the heteronormative board game where you play a family trying to fill its car with children.) Conway’s idea came from decades of mathematicians exploring the question, can simple systems produce complex behavior? Could a system with a few basic rules behave unpredictably? Could it produce self-replicating organisms? It’s not intended to be a realistic description of biology, it’s a mathematical game, which Conway called “the Game of Life”. John ConwayĪ mathematician named John Conway came up with these three rules around 1970. In the next step of the simulation it will be black. The empty white square in the center will spring to life.

Therefore, powerful tools are required for implementation. Many applications can only be implemented by using a complex model of processes. For fast data exchange between real-time and application level, events, shared memory, pipe mechanisms and sockets are available. Thus, it is possible to program and use accurate cyclic timers with frequencies of up tp 20 kHz. On exclusively used CPU cores, real-time capabilities can be increased even further, with timers having a maximum jitter of only about 1 microsecond. The deviation (jitter) amounts to only a few microseconds. The Kithara environment reaches the same level of performance as pure real-time systems and provides special real-time timers, that can be programmed with frequencies of up to several kilohertz. Our high-frequency timers for Windows are widely used in robotics, machine vision, measurement, control and automation.
