In the app, you can program your robot to complete activities and use pre-existing programs to explore their functionalities. To use these robots, you must first download the Sphero Edu App, which is available for download on iOS, Android, Kindle, Mac, Windows, and Chrome. Sphero SPRK+ and Sphero BOLT are both spherical robots that can be programmed to move in different directions, following real-world, drawn out pathways or digitally encoded directions. They’re also a lot of fun to play with at any age! Sphero: SPRK+ and BOLTĮager for more coding fun? With Sphero SPRK+, Sphero BOLT, and the Sphero Code Mat and Activity Card Set, you and your classroom can program even more robots to play games and embark on adventures! These robots and related activity kits are great hands-on learning objects to make coding and programming more tangible for classroom learners. The Ozobots are recommended for students in grade 1 and up, due to the small size and delicate nature of the robots. Again, students can simply use paper and markers to draw out the code by hand.įor education professionals who may want to familiarize themselves with Evo and Bit before introducing the robots into the classroom, helpful tutorials and tips and tricks can be found on the OzoBot website. Using the Evo app, students can earn points and level-up as they learn to code and create. There is also the option to have students simply draw out the code on paper.Įvo works very similarly to Bit, but is used in conjunction with the Evo app as opposed to the OzoBlockly website. The robots read colour sequences to follow commands, so students can create lines of coded instructions - or they can create entire drawings!īit uses OzoBlockly, an online tool, to allow students to direct it, and there are helpful videos and online instructions to facilitate the use of the website. Both Evo and Bit can be used with simply paper and markers, or they can be used in conjunction with their designated app or website. OzoBots, featuring Bit and Evo, are two brand-new activity kits that allow children to learn to code! If you are looking for hands-on coding fun, then these two kits will fit right into your classroom. This month, the OISE Library is featuring a collection of coding resources in our Display & Play area, including four robots! Coding in the classroom has never been so much fun (or so easy)!

The scientists ask: Can we intervene in a depressed state by reactivating positive memories? “You are what you have done what you have done is in your memory what you remember defines who you are.” If memories can be manipulated at will, what does it mean to have a past? If we can erase a bad memory, or create a good one, how do we develop a true sense of self? “Memory is identity,” the British author Julian Barnes writes in his memoir Nothing to Be Frightened Of. Though the work so far has been done on lab mice, the duo’s discoveries open a deeper line of thought into human nature. “The sky is really the limit now,” says Josselyn. Their work has launched a new era in memory research and could someday lead to new treatments for medical and psychiatric afflictions such as depression, post-traumatic stress disorder and Alzheimer’s disease. No one ever thought that you could actually, really do this.”Įxcept Ramirez and Liu. “A lot of people had been thinking along these lines,” says Sheena Josselyn, a senior neuroscientist at the Hospital for Sick Children in Toronto, who studies the cellular underpinnings of memory, “but they never dreamed that these experiments would actually work. The prospect of tinkering precisely with memory has tantalized scientists for years. “It’s a real breakthrough that shows the power of these techniques to address fundamental questions about how the brain works.” “It’s a fantastic feat,” says Howard Eichenbaum, a leading memory researcher and director of the Center for Neuroscience at Boston University, where Ramirez did his undergraduate work. The observation culminated more than two years of a long-shot research effort and supported an extraordinary hypothesis: Not only was it possible to identify brain cells involved in the encoding of a single memory, but those specific cells could be manipulated to create a whole new “memory” of an event that never happened. “Merry Freaking Christmas,” read the subject line of the email Ramirez shot off to Liu, who was spending the 2012 holiday in Yosemite National Park. Rather, it was reacting to a false memory that Ramirez and his MIT colleague Xu Liu had planted in its brain. Which was amazing, because the memory was bogus: The mouse had never received an electric shock in that box. Its memory of the trauma must have been quite vivid. It was a textbook fear response, and if anything, the mouse’s posture was more rigid than Ramirez had expected. Instead of curiously sniffing around, though, the animal instantly froze in terror, recalling the experience of receiving a foot shock in that same box. Steve Ramirez, a 24-year-old doctoral student at the time, placed the mouse in a small metal box with a black plastic floor. But creatures were definitely stirring, including a mouse that would soon be world famous. It was the day before Christmas, and the normally busy MIT laboratory on Vassar Street in Cambridge was quiet. Not technically the same as chamber pressure, but it’s from the same source. The farther down the barrel the gas port is located the lower the pressure will be by the time the bullet passes the port and the gas enters the port. No room for a dissertation on gas system operation, but as gas expands behind the bullet traveling down the barrel’s bore, increasingly greater volume is available for the gas to occupy, and time is also ticking away with respect to the flaming consumption of the propellant. The pistol-length-port location requires the least amount of post-build tuning to get 100 percent reliability. This is about the only time that intentionally ramping up gas port pressure is ever welcome on an AR-15! I’ve written thousands of words about its evils and ways to lower it for other applications. Supersonic would totally overstress this system. This is a 4-inch port location on a 16-inch barrel. A pistol-length gas system has been, for me, a key to getting fresh-off-the-workbench reliable function from subsonic Blackout. 30-caliber bullet gets put to work effectively because the pressure at the gas port is higher. Done like that, the relatively tiny amount of fast-burning propellant behind that honking. Run a pistol-length location gas port (4 inches ahead of the chamber area) with a carbine-length (16 inch) barrel. I have found that the best overall approach to subsonic function is to shorten gas system length. There’s not enough gas in subsonic, or there’s too much gas in supersonic, for both to function through a system set up more ideally for one or the other. So, despite what I’ve heard from many theorizing, you really can’t run supersonic and subsonic loads through the same gun, without modifications having been made to the gun. It works! Subsonic Architectureįirst, I’m always willing to risk boring knowledgeable readers with basic information, because it’s important to start at the start. Two Blackout barrels: carbine port location on the stainless pistol port location on the other. A 12 gauge slug, on the other hand, over-penetrates. Any bullet that’s built to either fragment or readily expand (not the same things but about the same effect) isn’t going to get far after it meets a solid object. This is really all about bullet design and bullet engineering. If anything, it’s the heavier bullets that are more likely to keep going. There’s much said, unsubstantiated, about over-penetration of higher-velocity bullets. Just a bit about the whole “defensive-rifle debate”: Some say something like, “5.56 is not a good choice for home defense.” I agree, but not for some reasons commonly given. (Clearly, supersonic Blackout beats it soundly.) 45 ACP is a reliable choice for a defensive round, subsonic Blackout beats it. 45 ACP handgun loading, if we’re going on (the admittedly incomplete) calculated energy figures. 300 Blackout subsonic loads are a little more powerful than a routine. 300 Blackout is plenty powerful, in my estimation, and with radically better shootability than a higher-pressure carbine loading. Most subsonic Blackout ammo uses a bullet in the 200-grain range, and, of course. That’s another debate for others to work though in other articles, but it’s my story and I’m sticking to it. Plus, I’m a believer in “bigger is better” respecting impact effectiveness of a bullet. Subsonic Blackout has a radically milder blast and report than 5.56 or supersonic Blackout. Now, there are some very effective flash suppressors out there, but they don’t take a bit off the noise. In the dark, maybe just up out of bed, and then there’s a blinding fireball and an ear-splitting report, and it’s difficult to recover situational awareness, especially at my age, and even with my rail-mounted light. Good stuff.Ĭivil? I don’t know how many have fired a 5.56 AR-15 carbine inside a room, but it’s sensory overload. Big bullet! My magazines currently hold my most-trusted Nosler 220-grain factory ammo. I built a specialty AR-15 for home defense that I also featured in recent book project, and that was my choice. One reason for its popularity is the supersonic/subsonic option. Pretty much, it’s for those who want a bigger bullet in an AR-15 with a minimum of technical distractions (some call them problems). I like it especially in the shorter guns, and, around here at least, it’s looked on as an effective Whitetail cartridge choice. 300 Blackout, aka: AAC, is a popular cartridge among AR-15 fans. Overall, ImageMagick is a powerful and versatile software suite for displaying, converting, and editing image files. These features make it a versatile tool for a wide range of image-related tasks, including graphic design, scientific visualization, and digital art. In addition to its core image manipulation capabilities, ImageMagick also includes a number of other features, such as support for animation, color management, and image rendering. This can be especially useful for tasks that require the processing of large numbers of images, or for tasks that need to be performed on a regular basis. This allows users to create complex image manipulation pipelines that can be run automatically, without the need for manual intervention. One of the key features of ImageMagick is its support for scripting and automation. It is strongly recommended to establish a security policy suitable for your local environment before utilizing ImageMagick. In addition, we maintain a legacy version of ImageMagick, version 6. The source code for this software can be accessed through a repository. The most recent version available is ImageMagick 7.1.1-15. The main website for ImageMagick can be found at. It is written in C and can be used on a variety of operating systems, including Linux, Windows, and macOS. ImageMagick includes a command-line interface for executing complex image processing tasks, as well as APIs for integrating its features into software applications. Its versatile and customizable nature, along with its robust image processing capabilities, make it a popular choice for a wide range of image-related tasks. ImageMagick is widely used in industries such as web development, graphic design, and video editing, as well as in scientific research, medical imaging, and astronomy. It can be used to create, edit, compose, or convert bitmap images, and supports a wide range of file formats, including JPEG, PNG, GIF, TIFF, and PDF. ImageMagick ® is a free, open-source software suite, used for editing and manipulating digital images. If you are a beginner to Java, the intricacies of JVMs will be a lot to wrap your head around. The resource intensiveness of compilation can be a bigger hit (especially for client-side applications) but it also enables more advanced optimizations. Some JVMs skip interpretation and rely on compilation alone. Some JVMs interpret application code on load and use performance counters to focus on "hot" code. JVM varieties and Java platform independenceĪll JVM implementations have one thing in common, which is their attempt to get application bytecode translated into machine instructions. Unless you make changes to your original source and recompile the code (using the compiler), the output will always result in the same outcome this is because the input is a static input and the compiler is a static compiler. With static compilers the input code is interpreted once and the output executable is in the form that will be used when the program is executed. In the following sections I'll explain a bit more.Īn example of a static compiler is the previously mentioned javac. I briefly discussed static and dynamic compilers in Part 1 of this series. From there, we have options depending on what execution environment we're targeting, what performance results we desire, and what resource restrictions we need to meet. The highest level of separation is between static and dynamic compilers. If you want to learn more about bytecode and the JVM, see " Bytecode basics" (Bill Venners, JavaWorld).įrom a platform-agnostic perspective we want to keep code platform-independent as far as possible, so that the last translation level - from the lowest representation to actual machine code - is the step that locks the execution to a specific platform's processor architecture. (See " JVM performance optimization, Part 1" for a JVM overview and introduction to the series.) I'll also discuss some common optimizations used by Just-In-Time (JIT) compilers for Java. This second article in the JVM performance optimization series highlights and explains the differences between various Java virtual machine compilers. The more that you understand about compilers, in terms of how they work and what kinds are available, the more you'll be able to optimize Java application performance. Different kinds of compilers meet various application needs, thus yielding specific desired performance results. A software developer writes the best Java application that he or she can, and then the compiler works behind the scenes to produce efficient and well-performing execution code for the intended target platform. She concludes with an overview of common JVM optimizations such as dead-code elimination, inlining, and loop optimization.Ī Java compiler is the source of Java's famous platform independence. Eva Andreasson introduces the different breeds of compiler and compares performance results from client, server, and tiered compilation. Java compilers take center stage in this second article in the JVM performance optimization series. Direct MIDI to WAV/MP3 Converter is a fast audio utility that lets you convert MIDI to MP3, WAV, WMA and OGG codecs.

A lot more people need to look at this and understand this side of the story. You certainly understand how to bring an issue to light and make it important. May I just say what a relief to discover someone that really understands what they're discussing on the web. They offer a few free DSD downloads to check out the sound high quality of their new DSD recordings. Apple likes to have their very own alternative for every little thing, however in actuality, there a small to none difference between flac and alac. To transform FLAC to 24 bit WAV, in Audio Settings” section, choose WAV 24bit” in the Encoder” drop-down. There is a answer while you want to convert your FLAC audio file and get great, excessive-quality results. Just drag and drop the audio files you need transformed instantly into the program, select an output format, after which begin the conversion. You know you can use dbpoweramp converter to go from FLAC to AIFF with out dropping your tagging data. As for converting from any lossy compression (like MP3 or AAC) to lossless or uncompressed (WAV, FLAC or Apple Lossless), there isn't any benefit more often than not as a result of it will probably't put again what has been already thrown away. Some of the advanced settings in Switch Sound File Converter embrace deleting the source audio file after a conversion, routinely flac2aiff windows normalizing audio, editing tags, and downloading CD album particulars from the Web. convert FLAC to MP3 Mac, convert FLAC to 16 bit/24bit WAV, convert FLAC to Apple Lossless ALAC, convert FLAC to M4A, convert FLAC to AIFF and convert FLAC to AC3, AU, MP2, OGG, RA and WMA in addition to preserve the audio quality. It will probably convert FLAC to broad audio formats e.g. Convert FLAC to AIFF in 16 Bit/24 Bit with no quality loss and 30x faster conversion speed. It is about 10 instances larger than a typical 128 kbps MP3 file. A: AIFF is CD quality that's the same file dimension as a traditional CD. WMA - Windows Media Audio is Microsoft's personal proprietary format, much like MP3 or AAC.Īn AIFF file is divided into chunks made up of Common Chunks, Sound data chunk, Marker chunk, Instrument chunk, Remark chunk, Title chunk, Author chunk, Copyright chunk, Annotation chunk, Audio recording chunk, MIDI knowledge chunk, Utility chunk and an ID3 chunk - it is just the Widespread chunk and Sound knowledge chunk that flac2aiff windows is required. Edit FLAC or any existed audio file like enhance audio volume, trim, change audio file dimension, alter audio channel, change audio bitrates, merge several audio recordsdata into one. FLAC to AIFF Converter creates output folders in line with supply files directory tree automatically. This AIFF Conversion app additionally helps to convert all types of audio codecs to AIFF. You possibly can attempt the following: take away the tracks out of your track folder, convert them into aiff and place the new files again in your monitor folder. Stick with AIFF as it's the only lossless format with correct metadata support (that's with imbedded cowl artwork) that can be performed by DLNA units and the help from Windows Media player ( File Formats Supported by Windows Media Participant Variations 6.0 and Later ) It's possible you'll not want it now, but perhaps a new machine in the future can play BD through DLNA and/or Airplay in addition to properley stream lossless files from network drives. An audio file converter is one kind of file converter that (shock!) is used to convert one kind of audio file (like an MP3, WAV, WMA, and so on.) into another kind of audio file. Rogers said when people can't take it anymore, they look for opportunities for change, and violence has been one means to achieving that change. 'Faith in the militant Black Power movement'įrustrations build. The notion of integration and civil rights, it's a 150-year story arc. And I think that's one of the issues why every 50 or so years you see this resurgence. Rogers is the historian at the Lucy Craft Laney Museum of Black History in Augusta. If this sounds familiar, Corey Rogers isn't surprised. The consensus was that jailers either killed Oatman or were willfully negligent. Not many Black Augustans believed that story. The morning of the riot, the district attorney William Barton charged two of the other juveniles, Sammy Lee Parks and Lloyd Brown, in Oatman's cell with his murder. "Foots" Atkins, promised to open an investigation. Abrams spread the word, and soon thereafter the county's sheriff, E.R. Jailers only said that he had fallen off his bunk after a card game. He had cigarette burns all over his body."Īn autopsy later found Oatman died by drowning: his lungs were filled with fluid. "He had three long gashes across his back, about a half an inch deep and about a foot long," he said. When his body arrived at Mays Mortuary, the undertaker, Carrie Mays was shocked. The city government had been putting off their infrastructure demands for nearly 20 years, according to City Council meeting minutes. Several Black neighborhoods lacked sewerage and water. Census showed only 20% of Augusta's African American adults held high school diplomas. Whereas our local officials have not seen a problem now our nation knows that Augusta has a problem," Green said. "The Black people of Augusta are tired of being told that there is no racial problem here. Green, who died in 2014, was African American. They described Black Augustans as happy and touted the good relations between Blacks and whites.īut then Augusta College's student body president, Henry Allen Green, told Atlanta's WSB-TV News in May, 1970 that Augusta's white leaders had been willfully blind. "And I don't want to say that everybody who was involved in the riot was a thug, but a lot of them were just criminals who were out stealing, that's all."Īt the time, many of the city's white leaders claimed to be flummoxed by the violence. "I don't know anyone knew why this so called riot took place," he said in a 2013 interview, prior to his death last year. Some, like former Richmond County Superior Court Judge Bill Fleming Sr., felt it was unimportant. News outlets do occasional anniversary pieces, but these are staid and seeming don't stick in anyone's mind. The Georgia Historical Society's director and staff say didn't event know about it until the committee's application for a state marker was submitted. The event went unmentioned and at present remains omitted from the Georgia Encyclopedia of History. Police killed six Black men.īut, until earlier this year as a result of a podcast and the 1970 Augusta Riot Observation Committee's efforts to raise awareness, most people in Augusta weren't aware this happened. More than 100 blocks of neighborhoods and businesses - about 7 miles - were ransacked and vandalized. They happened in 1970 in Augusta, Ga.įor two days, starting on May 11, 1,000 Black residents rebelled against the city's systemic oppression. In response, people protest in the streets and, violence erupts. Law enforcement's explanation of what happened doesn't line up with the boy's injuries. The story is all too familiar: a Black teenager suspiciously dies in a county jail. Approximately 300 people attended and 25–30 police officers stood watch. Protestors held a rally at a municipal building prior to the riot in Augusta, Ga., in 1970.

If you opt for a deep scan, the program checks the entire system and flags any spyware that it finds. SpyBot Search & Destroy free lets you scan your Windows device using its three different scanning options. Sometimes, when you download software programs from the internet, malicious spyware installs itself on your PC. In case you want to go back to automatic scanning and removal, you can easily switch back anytime you like. You can explore log files and decide when the application starts, scans, and displays warning threats. However, if you select the former and take manual control of SpyBot free, you can customize a range of the program’s operations. This option comes in handy if you’ve never worked with an anti-spyware tool before. If you select the latter, the program takes care of all its functions, including running background scans and removing unwanted software. The moment you start using the application, you will get a prompt asking you to choose between manual and automatic controls. Upon opening the menu, you can start or schedule a scan, customize operations, and manage cookies. The program then opens to a home screen containing a primary menu as well as a few toolbars with well-placed icons for specific functions. When you complete SpyBot Search & Destroy download and install it on your computer, a window opens up asking you to choose your preferred language. It runs in the background to protect you against privacy breaches and cyber attacks. For a safer-networking experience, SpyBot protects users against many types of spyware, including keyloggers, adware, tracking cookies, and malware attacks. SpyBot Search & Destroy free is such tool, detecting spyware on your computer and removing them instantly. However, once found, you can get rid of the malicious software with a spyware tool. Detecting these programs is extremely difficult, given they secretly run in the background collecting data without any consent whatsoever. Spyware programs are viruses designed to gather personal information such as your passwords, username, debit and credit card details, email accounts, and more. changed Shortened URLs about Google Storage: →.changed Modified content of each #rss feed in order to provide a better visibility into RSS readers.fixed About Chromium builds stored at SourceForge: If your browser does not send a referer header, you can directly download them.The full site is now based on the Git revision's commit hash.
