![]() Here is a screen capture of the digital pulses, with measurements shown on the bottom right. The difference between 1472 µs and 1500 µs is very small, and might not even be enough to make a difference in servo position. The pulse widths were measured using the oscilloscope’s built-in software, but manual measurements were in agreement. Here is what the outputs of pins 3, 4, and 5 looked like, from top to bottom: Servo3.write(90) // set servo to mid-point (90°) Servo1.write(90) // set servo to mid-point (90°) I uploaded the following code to my Uno, and analyzed the signals with an oscilloscope. But as it turns out, this assumption can lead to problems. That is, write(90) and writeMicroseconds(1500) should both send 1500 µs pulses. In theory, a write command that instructs a servo to adjust to 90° should send the same pulses as a writeMicroseconds command that sends 1500 µs pulses. Last Wednesday, my troubles all began when I instead used the write command with a parameter of 90°. Previously, I had used the servo library with the writeMicroseconds command, which defines the exact pulse width that you want to be sent to a servo. Most common servos accept inputs from 1000 µs to 2000 µs, with 1500 µs corresponding to the center position. In practice, attached servos will adjust to their center positions, but perhaps not exactly. For a continuous-rotation servo, this will halt the servo’s motion. This sample code instructs a servo, connected to pin 9, to move to its center (90°) position. Myservo.write(90) // set servo to mid-point ![]() Arduino ServoWriteĪrduino’s servo library makes it easier to control servos with minimal code and complications. Arduino’s reference page for the ServoWrite command, which draws upon the servo library, offers the following example code: #include This might seem like beginner stuff, but until last week’s complications I have used Arduino’s servo library quite a few times with ease and assumed proficiency. The result – a better fundamental understanding of Arduino’s servo library, which I will try to share with you with this post. I described the account over at ToolGuyd ( An Oscilloscope, an Arduino Servo PWM Signal, and a Wild-Goose Chase) if you’re interested in the whole story. I wouldn’t call the experience a waste of time, but the experience occupied more of my time than I would have liked. Last Wednesday I spent most of the morning and part of the afternoon chasing a signal anomaly that, as it turns out, did not exist. Gift the gift of Make: Magazine this holiday season!

![]() You will also need to create a new private API key on Zotero. Next, create an heroku application which will host the server heroku create git clone git:///krueschan/phpZoteroWebDAV.git You should start by cloning the git repository on your local machine. Amazon S3 could also be an interesting choice. ![]() The Heroku PostgreSQL database could be a solution. The data will then need to be stored in an other media. ![]() Hosting a WebDav server on heroku is technically possible, as demonstrated by phpZoteroWebDav. Obviously, both of these directories aren’t reliable for long-term data storage. However, the way phpZoteroWebDav is built makes the usage of the filesystem. Heroku is awesome for production use of course. It allows us to quickly provision a new server with only what we need on it, run our tests and have it kept running for later use. This is exactly the type of need where we find Heroku to be an excellent solution. Thanks to him.įor our development and test purposes, we wanted to facilitate even more the deployment of this application, without the hassle to configure a web server with PHP and run an application there. The original phpZoteroWebDav repository is not maintained anymore. Written in PHP, it’s a quick and easy solution to deploy a WebDav server on any HTTP server and synchronize your Zotero library with it. That’s probably not something you have on your desk.įortunately for us, there is phpZoteroWebDav. If you’re poking around the SZNZotero SDK, you will probably need your own WebDAV server to develop and test your applications. But you can host them and synchronize them with the WebDav protocol. You don’t need to host all your publications on their platform. One of the things we love about Zotero is the possibility to decentralize your data there. This SDK allows you to build awesome applications for iOS and OSX around the Zotero APIs. Lately, we released our Objective-C SDK for Zotero.

Addictive rhythm gameplay | What makes Hi-Fi RUSH really outstanding is the gameplay.Honestly, something that Xbox can really use! You just can’t help but fall in love, I’m sure Xbox has two new character mascots. They often show some slow-motion cutscenes and the action scenes with the two of them are highly detailed. Chai and cat 808 are videogame stars with awesome cutscenes with fantastic facial expressions. Side characters that say the weirdest things in conversations with your sidekicks are hilarious to follow. Each and every person and robot has a lot of personality. Hi-Fi RUSH has more personality than most games combined | From the main character Chai, to support characters or enemies.You really have to see it, as reading about it somehow feels less impressive. The thing that is massively impressive is how everything is synced with the music, how Chai walks, how support characters join your fight, blocking, small visual details in the environments, and Chai’s finger-snapping. ![]() From licensed to originally created music, everything sounds great and you’ll be moving your head up and down while Chai is exploring the levels or fighting against not-so-friendly robots.
![]() Just click on one of the them to apply it as background. We have added 4 predefined gradients, which can directly be used as background for folders. Color or color gradients as background for folders This can be achieved in the folder properties area. In the grid and list perspectives, you can now define an image or a color gradient as background for every folder. Color gradients for folder background PRO You can also switch off the collection of this information, by selecting the "disabled"-entry in the dropdown. In the advanced tab of the application settings, you can adjust the amount of files/folders collected in the lists. The lists with the recent files are stored in the local storage of the app (or the browser for the web based app), so this is as expected a pure offline functionality. ![]() You can also delete the bookmark by clicking the button with the minus icon on the right. Hovering the bookmarks icon will show a tooltip containing the path to the bookmarked entry the date of the bookmark creation. A click on the bookmark will open in the file or the folder in the preview area. Once you have created a bookmark, you can go to the quick access area and open the bookmarks list. This can be achieved by clicking on the button highlighted in the next screenshot. Now in version 5 you can create a bookmark for any file or folder, regardless if it is local on your pc or stored remotely on an S3 bucket.
![]() It’s best known for its antivirus software, but now sells a range of cybersecurity products. Avast VPN Operates Under EU JurisdictionĪvast RSO is a Czech cybersecurity company founded in 1988. Sadly, Avast makes it abundantly clear it will hand over your data to government agencies. The problem is the content of the privacy policy. Moreover, Avast has a privacy policy for its VPN specifically (and another for its browser extension), and not a vaguely worded policy for all Avast products, like other antivirus companies have. This is the most sensitive information that no VPN should keep. There’s no real justification for this practice.Īt least Avast SecureLine doesn’t store your original IP address, DNS queries, or browsing history. Ultimately, there are far more effective and cheaper VPNs available than Avast SecureLine.Īvast’s VPN privacy policy is clearly written and transparent, but the service logs more data than we’re comfortable with.Īvast’s servers store your connection data for 35 days, and any client data (account information) for up to two years. However, the VPN logs an unacceptable amount of user data, and it can only unblock a small selection of streaming websites. In short, Avast SecureLine is a fast VPN service that will reliably hide your IP address, preventing websites and third parties from tracking your activity and true location. ![]() The company’s troubled company history is also concerning. More worryingly, Avast VPN keeps too many user logs and is subject to EU data retention laws, too. Its server network is also limited compared to other popular VPN services. We were especially disappointed by how few streaming services it unblocks. What transpired from reviewing Avast SecureLine is that the VPN’s proprietary Avast Mimic protocol is very fast, but the VPN falls short in many key testing areas. We also tested the VPN to see how effectively it bypasses streaming and censorship content filters. In our review of Avast SecureLine VPN, we tested each application to assess the service’s ability to protect your internet privacy and security. The VPN software is consumer-friendly and easy to use, but we’ve seen far better VPNs. Avast SecureLine is an average VPN from cybersecurity giant Avast RSO. The dark and desolate atmosphere of the game is meticulously recreated, immersing the audience in a hauntingly beautiful and treacherous world. The series captures the essence of the original story and evokes the same emotional impact. ![]() The faithful translation of the game's narrative into a serialized format is commendable. The series' visual direction deserves immense praise, with its stunningly crafted locations that transport viewers into the post-apocalyptic world with astonishing realism. ![]() Pedro Pascal's portrayal of Joel and Bella Ramsey's embodiment of Ellie showcase their exceptional acting abilities, adding depth and authenticity to their characters. The Last of Us series stands as a remarkable and successful adaptation of a beloved video game into a captivating television show. Lastly, while insects do gain some level of aggression when infected, they normally do not attack other insects. All 600 species of Cordyceps which seize control of insect bodies do so to force the host into a humid place where the fungus can feed on the body and spread its spores, so if an evolved cordyceps infected a human and over the course of many days transformed the body into a shambling host, the fungus' end goal would be much the same. Even if it did, fungal infections are slow, taking a matter of weeks, and nothing like the near-instant transformation depicted new filaments take some time and energy to produce. Human brains contain hundreds of thousands of times more neurons compared to an ant brain, and it would be an extraordinarily rapid evolution for cordyceps to gain the ability to infect and take over one. ![]() Overall, the probability of a fungus of this type evolving the need and capability to infect humans is astronomically small. As with the game, the series' depiction of the cordyceps fungus has some inaccuracies. You will be permabanned for all the above with no warning.ġ.

![]() Every enemy spawns on a timer and you are always in the same circular arena so you can memorise the position and timings of waves but you get overwhelmed that quickly that if you aren’t on the ball, it becomes impossible to quell the storm. Devil Daggers is a grind, a slow process of mastering each wave of monsters before eventually pushing onto the next whirlwind of pain and then mastering that. You may eventually do that one minute long run and feel amazing then go back to never getting past 40 seconds. After about 30 tries, you may get up to 30 seconds before a new demon comes out of the shadows and sideswipes you. When you first start Devil Daggers, you’ll probably last 15 seconds. Once you get hit once, your run is over and you start the gauntlet of grotesquery again. The movement is similar to a shooter from the 90s, with you strafing and jumping past clouds of skeletal horrors at high speed, as you desperately try to clear that spire before the giant screaming spider pops out and starts spewing acid everywhere. Besides that and eventually unlocking a homing shot once you have collected 70 glowing gems, which drop from certain demons, that’s everything you can do in Devil Daggers. Using the powers of the Dagger, you can shoot a shotgun blast of bloody fragments if you click the left mouse button once or you can fire a steady stream of viscera if you hold the button down. Upon picking up the aforementioned blade, you are thrust into a blank arena where demonic spires and demons start to attack you from all sides. ![]() The only thing you do in Devil Daggers is survive. ![]() Hell is other people in Devil Daggers and all of them are vying to beat your score by whatever means necessary. The hellscape of Devil Daggers is an endless gauntlet of skulls and eldritch horrors, where success is fleeting yet tantalising, as the world leaderboard of fellow damned souls constantly reminds you that you can go that little bit further. Devil Daggers keeps the twitch shooting of something like Doom or Quake but throws away the boiling pits of acid and goes much darker, with torrents of demons spilling over you as you shoot them away with blasts of blood and bone. Doom added some metal to the infernal mix and gave the demons some robot arms but the kingdom of the diabolical still stuck to the tried and true depiction of Lucifer’s domain. There’s always some fire, brimstone, lava and possibly a pointy-horned demon cackling at the damned, with artists and designers very rarely straying from the same design of Hell which has been popular since doom paintings from Norman churches. Hell has become one of those go-to levels for game design, being as exciting as the snow or desert area. You can select specific sections of the screen, adjust the image quality or add other elements like filters or overlays. It serves as an interface between the computer and the streaming platform, and it offers numerous possibilities to modify the original screengrab.

Emotional annotation of massive music works based on artificial methods is not only a huge workload, but also the quality cannot be guaranteed. To achieve emotion-based music classification and retrieval, it is necessary to label music works with emotions. Therefore, emotion-based music retrieval is an important part of meeting people’s personalized music retrieval needs, and it is also an important development direction of current music retrieval. There are relatively few intelligent classification of music emotions and emotion-based search services. In order to obtain a better user experience, in recent years, various listening platforms have begun to provide song recommendation services with different moods. Recommend similar songs in the music library according to the needs of users and the songs that users often listen to. For these needs, many music websites have also launched music recommendation services. The traditional methods of retrieving music information can no longer meet people’s needs for intelligent and personalized music retrieval ( Casey et al., 2008). This method is currently the most commonly used method. Traditional music retrieval methods are based on classification tags, such as retrieving songs by song name, artist name, and album name. With the rapid increase of music file data, how to use computers to complete fast and effective music information retrieval has become a basic demand of people in the current society. Music has been integrated into all aspects of life including waking up, eating, shopping, learning, sports, driving, education, medical care and so on. During the medical process, appropriate music will be selected to provide psychological counseling to the patient. Exciting and rhythmic music is played during the party, which can set off the joyful atmosphere of the party. Playing soft music during a break can soothe the nerves. Playing rhythmic music during exercise can increase the enthusiasm of exercise and reduce exercise fatigue. Stores often play dynamic music to arouse customers’ desire to buy. The changes in creation, storage, dissemination, and technology have made music play an increasingly important role in human social life. With the development of science and technology, the creation, storage, and dissemination of music have all undergone tremendous changes. Music plays an important role in the history of mankind, and music is integrated into all aspects of human life. Music appeared earlier than language, and human beings are born with music to express feelings. Through experiments on public music data sets, the experimental results show that compared with other comparative models, the MER method used in this paper has better recognition effect and faster recognition speed. BP neural network with ABC algorithm can improve the global search ability of the BP network, while reducing the probability of the BP network falling into the local optimal solution, and the convergence speed is faster. The ABC algorithm is responsible for adjusting the weights and thresholds, and feeds back the optimal weights and thresholds to the BP neural network system. The output value of the ABC algorithm is used as the weight and threshold of the BP neural network. This paper introduces artificial bee colony (ABC) algorithm to improve the structure of BP neural network. Because the traditional BP network tends to fall into local solutions, the selection of initial weights and thresholds directly affects the training effect. In this paper, an improved back propagation (BP) algorithm neural network is used to analyze music data. Second, it is difficult to analyze music emotions based on the pitch, length, and intensity of the notes, which can hardly reflect the soul and connotation of music. First, the emotional color conveyed by the first music is constantly changing with the playback of the music, and it is difficult to accurately express the ups and downs of music emotion based on the analysis of the entire music. The existing music emotion recognition (MER) methods have the following two challenges. Paying more attention to the emotional expression of creators and the psychological characteristics of music are also indispensable personalized needs of users. ![]() At the same time, the demand for music organization, classification, and retrieval is also increasing. Music plays an extremely important role in people’s production and life. Zhejiang Conservatory of Music, Hangzhou, China. |
