Apple MagSafe für iPhone 12 Ladegerät Unboxing [Deutsch]
Yes, hello folks It’s finally time again, there is a new video. I know it hasn’t been in a long time, but I figured the Apple Store finally got MagSafe, so I went and bought it already. As you can see, on the side: a lot of bullshit On the other side: even more bullshit On the back we see that a 20W charger is needed I hope that the 18W charger will also work, because I don’t have a 20W charger But, like we know, the whole thing also works with the old iPhones, so I don’t need a new iPhone to be able to use it.

Comparing cost and performance for Oracle Database, EnterpriseDB and Tibero Database
Hello and welcome! These are challenging and unpredictable times, more than ever your company needs a database solution that provides value for money. In this slide we emphasize that data access through SQL “SELECT” is the time consuming operation typically 99% of the database engine’s processing time is spent on this operation. Note that SELECTs happen implicitly for most UPDATEs and DELETEs which are also very common operations in your application so how quickly your database processes selects will determine your application’s efficiency the productivity of your employees and therefore the company’s profitability clearly fast select access to data cannot come at any cost so in this video presentation we will be looking at a very interesting cost performance comparison between four key database solution providers these are tibero oracle enterprise edition oracle exadata and enterprise db postgresql throughout this presentation we will use the acronym cpr for cost performance ratio the overall cost you consider should not simply be the initial price of the product and its service fees the real cost needs to take into account the important effect of the database performance if your employee clicks for a report and then waits 30 minutes for it to finish then this is effectively a downtime of 30 minutes for that employee regular downtime for many employees means damaging lost productivity as importantly if you have long running reports or workloads these will consume more cloud computing resources and your monthly bill will be higher you will harm your company by purchasing a database solution with performance disadvantages in this slide we show the environments we used for the tests you can see real world configurations from four different customers and the price they paid for each configuration over five years we chose five years because it is important to not merely look at initial purchase cost but to add in the license fee costs over the longer term the infrastructure and software configuration hosting each database represent the likely real world scenarios you can see the actual costs that would be paid by the customer over a five years operation this includes hardware software and ongoing yearly licenses so what approach did we take to compare database performance and give you a cost price ratio for those different solutions well we firstly grabbed a 128 gigabyte data set from oracle db we migrated this to each of the different database environments in typical configurations of memory and cpu then we executed and timed six sql statements that represent normal day-to-day operations for any database the software tests were identical in each environment and care was taken to ensure there were no competing processes so here’s what you’ve been waiting for the results let me navigate you through the results and their interpretation in this table we are looking at how the same queries perform for each solution each row represents a different sql test and you can find the exact sql statements in a later slide each column heading shows you a client’s solution in terms of database memory and cpu configuration just to clarify faster response times inside the table correspond to a lower number of seconds so client a represents a big german company that owns a regular oracle enterprise edition its timings range from 38 seconds to an execution time so large that it didn’t finish it’s important to compare these timings with those of oracle atp and oracle adw the timings for these two were far better but their total cost is considerably more expensive and for all three clients we are still talking about the same database provider oracle so now let’s compare oracle solutions with other database vendors take a look at the timings for the regular oracle enterprise edition and compare this with the timings for the enterprise db postgresql scaled out solution well edb performed three to ten times worse than this oracle solution whilst its five-year cost of two million dollars is about 15 times more expensive so it is worse than regular oracle on both key measures we can say that the delete operation for edb did succeed when oracles didn’t however it took nearly six hours to delete the data and this isn’t acceptable in real life scenarios oracle ee regular solution has a better cost price performance than the edb solution now we again compare oracle enterprise edition but this time with tibero database oracle ee has a five-year cost three times the cost of tobero however if you compare the timings you can see that the tibero performance was considerably better around 30 times faster tibero database clearly has a much better cpr than oracle enterprise edition so what happens when we move to clients using much more powerful oracle configurations first take a look at the much publicized oracle exadata first the autonomous data warehouse version this is the best oracle solution for olap and its five-year costs amount to an eye-watering 4.

Science in Seconds: The ACTIVATE Project
Hey this is Dr Thomas Z with another Science in Seconds and I’m so excited to have Dr. Armin Sorooshian of the University of Arizona with us he’s the Principal Investigator of the ACTIVATE team and I met that team. I was at Langley and two airplanes came in and his team got off the plane that was the last flight of the ACTIVATE mission this year. So Armin, tell us more about ACTIVATE.

Will it Unblend?
Hi, I’m Yuval Pinter, presenting our paper titled “Will it Unblend?”. This is work with Cassandra Jacobs from the University of Wisconsin, and Jacob Eisenstein, my PhD advisor, now at Google Research. A few weeks ago, my seven- year-old daughter first heard someone mention the word “brunch”. She asked me what it meant, so instead of just telling her, I walked her through it. Okay, that person mentioned that there’s going to be food at brunch.

English Electric 8Switch audiophile network switch
English Electric sounds familiar but from what. And how good is their only product, the 8Switch audio grade network switch? The influence network switches have on the sound quality of a network player has been a point of discussion for some time now. Especially those that did not tried it, are critical. Those that did, are sold. For those that wonder what it is all about: a switch is a kind of distribution center for network connections.

LiverScreen: Spotting chronic liver disease before it’s too late
Chronic liver disease is a silent killer. Among the millions who die from the disease each year, many can go as long as 20 years without knowing anything is wrong. By then, when cirrhosis has already set in, it’s often too late. But according to researchers from Europe, it doesn’t have to be this way. They’re embarking on a monumental project they’ve dubbed “LiverScreen”. Using cutting-edge technology, their mission is to devise and evaluate a screening strategy for detecting chronic liver disease early enough to take action.

QT Medical - Personal 12-lead ECG The 12-lead Electrocardiogram, ECG or EKG is the medical standard for diagnosing many cardiac conditions. However, the conventional process is cumbersome, time-consuming and requires trained technicians. In some medical emergencies, a 12-lead ECG could provide vital information, but there are no professionals available to perform the test. But with PCA 500, 12 lead ECG tests can be performed by anyone in places like airplanes, cargo ships, oil rig, mining sites, or jails.
