Leader node compiles code for individual elements of the execution plan and assigns the code to individual compute nodes.All other queries run exclusively on the leader node. Leader node distributes SQL statements to the compute nodes only when a query references tables that are stored on the compute nodes.Based on the execution plan, the leader node compiles code, distributes the compiled code to the compute nodes, and assigns a portion of the data to each compute node.It parses and develops execution plans to carry out database operations.Leader node manages communications with client programs and all communication with compute nodes.Compute nodes are transparent to external applications.Client applications interact directly only with the leader node.If a cluster is provisioned with two or more compute nodes, an additional leader node coordinates the compute nodes and handles external communication.Cluster is composed of one or more compute nodes.Core infrastructure component of a Redshift data warehouse.Compiling the query decreases the overhead associated with an interpreter and therefore increases the runtime speed, especially for complex queries. Leader node distributes fully optimized compiled code across all of the nodes of a cluster.Result caching is transparent to the user.If a match is found in the result cache, Redshift uses the cached results and doesn’t run the query. When a user submits a query, Redshift checks the results cache for a valid, cached copy of the query results.Redshift caches the results of certain types of queries in memory on the leader node.Redshift query run engine incorporates a query optimizer that is MPP-aware and also takes advantage of columnar-oriented data storage.automatically samples the data and selects the most appropriate compression scheme, when the data is loaded into an empty table.doesn’t require indexes or materialized views and so uses less space than traditional relational database systems.employs multiple compression techniques and can often achieve significant compression relative to traditional relational data stores.Columnar data stores can be compressed much more than row-based data stores because similar data is stored sequentially on a disk.columnar data is stored sequentially on the storage media, and require far fewer I/Os, greatly improving query performance.organizes the data by column, as column-based systems are ideal for data warehousing and analytics, where queries often involve aggregates performed over large data sets.makes it easy to add nodes to the data warehouse and enables fast query performance as the data warehouse grows.automatically distributes data and query load across all nodes.Redshift can be easily enabled to a second region for disaster recovery.Redshift provides Audit logging and AWS CloudTrail integration.Redshift provides monitoring using CloudWatch and metrics for compute utilization, storage utilization, and read/write traffic to the cluster are available with the ability to add user-defined custom metrics.Redshift only supports Single-AZ deployments and the nodes are available within the same AZ if the AZ supports Redshift clusters.supports VPC, SSL, AES-256 encryption, and Hardware Security Modules (HSMs) to protect the data in transit and at rest.distributes & parallelize queries across multiple physical resources.scale up or down with a few clicks in the AWS Management Console or with a single API call.uses replication and continuous backups to enhance availability and improve data durability and can automatically recover from node and component failures. ![]() provide fast querying capabilities over structured and semi-structured data using familiar SQL-based clients and business intelligence (BI) tools using standard ODBC and JDBC connections.significantly lowers the cost of a data warehouse, but also makes it easy to analyze large amounts of data very quickly.monitors the nodes and drives to help recovery from failures.patches and backs up the data warehouse, storing the backups for a user-defined retention period.set up, operate, and scale a data warehouse, from provisioning the infrastructure capacity.Redshift is an OLAP data warehouse solution based on PostgreSQL.Amazon Redshift is a fully managed, fast, and powerful, petabyte-scale data warehouse service.

Our VP of Product, Jonathan Cran presented at the DEFCON Recon Village and demoed our integration with Qualys at the Qualys booth. If you missed these talks, dont worry! JP will be doing another talk on the HUNT at AppSec USA 2017 Jason Haddix and JP Villanueva held several talks across both Black Hat and DEFCON around the HUNT methodology, examining data-driven web hacking and manual testing. ![]() We had a few of our top security researchers at the booth, engaging with customers, prospects and partners. ![]() We had our first-ever Black Hat booth, which featured our new design and product video. This year’s Black Hat event was quite the milestone for Bugcrowd. Not to mention we debuted our new shirt design and collateral for the week. It was great kicking off the week with BSidesLV, which is getting bigger and better! We had great conversations with the security researcher community and those interested in working with the security researcher community.

Its colour is actually a blue-grey, with shades of red-orange and brown also prominent, as well as iridescent markings at the neck.The passenger pigeon is sometimes called a 'wild pigeon' or 'blue pigeon'.Picture courtesy of the Biodiversity Heritage Library. ![]() Mark Catesby's 1754 illustration of a passenger pigeon. The first published depiction of the species is believed to be by Mark Catesby, in The Natural History of Carolina, Florida, and the Bahama Islands volume 1, in 1754, although he called the bird Palumbus migratorius, the pigeon of passage.He mistook the birds he saw for the wild pigeons he was familiar with in Europe but it was later agreed that what he had seen were passenger pigeons. Journeying along the shore of Prince Edward Island, Cartier noted in his journal: 'an infinite number of wood pigeons'.The first recorded mention of the passenger pigeon was by ship captain Jacques Cartier in July 1534.Ectopistes means 'moving about or wandering' and migratorius means 'migrating'.It was later re-classified as Ectopistes migratorius because of its longer wings and tail, and larger overall size, than the dove family Columbidae.It was officially described by Carl Linnaeus in 1766 as Columba migratoria.The scientific name for the passenger pigeon is Ectopistes migratorius.To commemorate, I (with some invaluable help and contributions from my Museum colleagues, the Smithsonian Institution, and Joel Greenberg's book A Feathered River Across the Sky: The Passenger Pigeon's Flight to Extinction) have compiled a list of 100 passenger pigeon-related facts. ![]() After the dodo, it is one of the most famous examples of human-caused extinction in the world. Today is the 100th anniversary of the death of the last living passenger pigeon. 7/26/2023 0 Comments Mdm server url apple configurator![]() ![]() Otherwise, it remains permanently in School Manager. Within this period, you can unlock the device again and remove it from School Manager without any problems. Note: For manually added devices to the Apple School Manager there is a transition period of 30 days. Furthermore, the devices are clearly marked as property of the university and individual institutes / projects and can be locked and located in case of loss or theft. For iPads, for example, this concerns the single app mode or other restriction options that are of interest to many users. Only through automatic device enrollment can you fully utilize all the device management features available in Jamf School (or indeed other MDMs). The DEP is also the registration method recommended by Apple. If the devices are added to the DEP of the Apple School Manager of the University of Cologne, this is prevented. The possibility to delete these profiles on the user side is therefore counterproductive. Only by means of these MDM profiles remote control works correctly. These profiles are installed on every device that is managed by an MDM. Nevertheless, "non-supervised / supervised" devices can also be extensively supervised in Jamf School. For more info on this, please also refer to the Jamf doc on device enrollment. Other restrictions and device configurations can also only be configured on supervised devices. If you plan to use a / our Mobile Device Management (MDM) Jamf School to manage the devices, you don't necessarily need to add the devices to Apple School Manager or DEP, but it is strongly recommended as only automatic device enrollment (formerly Device Enrollment Program, DEP) prevents users from removing the MDM profile from the devices. However, this only applies to iPads and Apple Tvs Macs cannot be manually re-registered using Apple Configurator. This article will cover both Apple Configurator 2 MDM enrollment options in detail: DEP automatic enrollment method and manual enrollment URL method. If you already have devices in your inventory, if new devices are added individually or if devices have been donated, for example, you can also add the devices manually to the Apple School Manager. Especially for large orders this is highly recommended. If you are planning to purchase new devices, you have the possibility to order them directly from the reseller for a fee. This will automatically register the devices with the Apple School Manager at the University of Cologne. In order to use the full functionality of the remote maintenance of mobile Apple devices, it is strongly recommended to add the devices to the so-called Device Enrollment Program (DEP) of Apple.

I joined Amazon Prime at a cost of 7.99 per month (recently increased to 8.99 but still good value) purely to access Free Delivery on Amazon Purchases which we use a lot. What did you think of our guide? Are you less confused about Prime Reading, Kindle Unlimited and Amazon’s ecosystem than you were before? Are there any details you think we missed or could have expanded on? Let us know in the comments below. That said, we don’t think the selection is impressive enough to warrant a Prime subscription just for that, but luckily you get a bunch of other benefits as well. Although it’s not as extensive as its big brother Kindle Unlimited, Prime Reading is still an excellent bonus if you already have a Prime membership. That brings us to the end of our Prime Reading rundown. Whereas Prime Reading is limited to a few thousand books and magazines, Kindle Unlimited contains more than 2 million titles. You can check out our Prime Reading vs Kindle Unlimited comparison to get a full rundown, but the biggest difference between the two programs is in the quantity of books and audiobooks available. If your Amazon account has an active Prime subscription, you’ll see the Prime logo on any free book or other Prime Reading work. Does Prime Reading Come With an Amazon Prime Membership?.If you’re more curious about the latter, you can check out our full Kindle Unlimited guide instead.įurthermore, Prime Reading and Kindle Unlimited work great with Amazon Fire Tablets or Kindle e-readers, so if you don’t have one you can read our Kindle model comparison and Kindle vs Fire comparison to learn more. Prime Reading and Kindle Unlimited are both services that let users add free books to their private libraries and retain them as long as their subscription remains active. Kindle Unlimited is a separate service that costs extra, but contains a much larger selection of titles than Prime Reading does.There are roughly 3,000 titles available with Prime Reading, including books, magazines, comic books and audiobooks. ![]() Prime Reading is included with every Amazon Prime membership.Prime Reading is another part of the multi-benefit subscription, but what is Prime Reading? Keep reading to learn all the ins and outs of the Prime benefit. Initially, the sole Prime benefit was free two-day shipping, but it has since expanded to include other benefits at no extra cost, such as Amazon Prime Video. If you’ve ever used Amazon to buy anything, you’re probably aware of Amazon Prime. ![]()
7/25/2023 0 Comments Inside of a vhs tape![]() The Mylar tape is actually hazardous due to the metals on its surface.įriedman says products with profitable metals, like cell phones and computers, are often easier to find recyclers for, because of the money that can be made from the materials. The tape inside is made from #1 plastic but is coated in a few different metals, making it difficult to recycle. The outside case of the VHS tapes is made from #5 plastic (polypropylene). “The outside casing is made from different types of plastic and that can be recycled it’s the Mylar tape that really can’t be,” he says. ![]() “One of the bigger problems is that there’s this massive amount of VHS tapes and there really isn’t a great solution for recycling them,” says Mickey Friedman, COO for GreenDisk, one of the largest e-waste recyclers in the U.S.įriedman says it’s been hard for the company to recycle all of the pieces associated with magnetic media. Why is it so difficult to recycle VHS tapes? ![]() Photo: Kirill ReinhartĬome to think of it, you probably have that Poison cassette and a slew of old VHS tapes somewhere right now, don’t you?Īll of these obsolete VHS tapes and audio cassette tapes, collectively called magnetic media, are actually a huge waste problem. Remember putting on those neon pink legwarmers or rolling up the sleeves on your white blazer and rocking out to that Poison cassette tape? Or pressing record on your VCR to catch the latest episode of Charles in Charge? Obsolete audio cassette tapes and VHS tapes pose a problem for many recyclers. ![]() In the case of non-CO 2 greenhouse gases, sinks need not store the gas. In the context of climate change and in particular mitigation, a sink is defined as "Any process, activity or mechanism which removes a greenhouse gas, an aerosol or a precursor of a greenhouse gas from the atmosphere". In addition to enhancing natural processes, investments in artificial sequestration initiatives are underway to store carbon in building materials or deep underground. These efforts counter historical trends caused by practices like deforestation and industrial agriculture which depleted natural carbon sinks land use, land-use change, and forestry historically have been important human contributions to climate change. Many efforts are being made to enhance natural carbon sinks, mainly soils and forests, to mitigate climate change. As a main carbon sink, the ocean removes excess greenhouse gas emissions such as heat and energy. Deep blue carbon is located in the high seas beyond national jurisdictions and includes carbon contained in "continental shelf waters, deep-sea waters and the sea floor beneath them. Coastal blue carbon includes mangroves, salt marshes and seagrasses which make up a majority of ocean plant life and store large quantities of carbon. " Blue carbon" designates carbon that is fixed via the ocean ecosystems. Much of the organic carbon retained in the soil of agricultural areas has been depleted due to intensive farming. Soil is an important carbon storage medium. ![]() Globally, the two most important carbon sinks are vegetation and the ocean. A carbon sink is a type of carbon pool that has the capability to take up more carbon from the atmosphere than it releases. An overarching term is carbon pool, which is all the places where carbon can be (the atmosphere, oceans, soil, plants, and so forth). These sinks form an important part of the natural carbon cycle. Ī carbon sink is anything, natural or otherwise, that accumulates and stores some carbon-containing chemical compound for an indefinite period and thereby removes carbon dioxide (CO 2) from the atmosphere. Together, they are part of the carbon budget which is no longer in balance since the 1850s, causing a nearly 50% rise in atmospheric carbon dioxide concentration. Carbon sinks (green bars on the right) remove carbon from the atmosphere, whereas carbon sources ( greenhouse gas emissions) (grey bars on the left) add them. ![]() Pricing for the Hybrid actually goes down for 2021. Toyota upgraded the Camry to its Toyota Safety Sense 2.5 systems, bringing enhanced auto emergency braking with pedestrian detection, full-speed adaptive cruise control (can bring vehicle to stop and start again on its own), lane-tracing assist (keeps car centered in lane), auto high-beams, road sign assist and Toyota’s rear seat reminder. The last notable tech update for 2021 is improved driver assistance and safety equipment. ![]() Toyota just pulled the displays out of the RAV4 and dumped them in here. Both run Apple CarPlay, Android Auto and Amazon Alexa as standard. You can upgrade to a nine-inch version of the display. The new base infotainment setup uses a newly-integrated seven-inch touchscreen. In addition to the new styling, Toyota upgraded the infotainment systems options in the 2021 Camry. If it’s a sporty trim, Toyota has added a patterned metal package. If it’s a model aiming at comfort, you’ll get a dark wood look. Plus, all grades get a revised set of interior trim appointments. On the inside, Toyota is debuting a new Herringbone seat pattern on the XLE. New wheel designs also make their debut on LE and XLE models this year. ![]() It’s been amplified and made even more dramatic this year, and it’s starting to become a bit much to take in. The entire front bumper is essentially all grille now. If boring, hybrid-car looks were keeping you from going Camry Hybrid, Toyota appears to have a solution for that now.īoth the LE and XLE grades get a revised front fascia for 2021, too. It looks just like the XSE grade for the standard Camry, which gets an even bolder honeycomb style grille this year. It’s pictured in gray here, and if not for the blue Toyota logo and Hybrid badge, we’d never assume this model was the eco-focused one. This brings the sportier suspension tuning and aggressive appearance package to the greenest of models. Toyota added an XSE grade to the Hybrid trim to start. It’s not a full-fledged mid-cycle update, but the changes are welcome nonetheless. The 2021 Toyota Camry gains both visual and technology improvements in the new model year. 7/25/2023 0 Comments Download loom video from link![]() Below ‘Invite team members’ you have ‘Home’.This will allow your teammates to create their own Looms, and collaborate with you on your Looms.
