![]() It does contain a vulkan driver but I wouldn't even expect it to work with SteamVR. ![]() The thing is that SteamVR is moving fast and requires relatively recent graphics drivers and for example direct mode will only work with the very newest releases.Īmdgpu-pro is the proprietary AMD driver. If you have vulkaninfo and running "vulkaninfo | grep deviceName" prints something with your GPU name in it, then vulkan is working. One of the optional little standard utilities for vulkan is "vulkaninfo", maybe in a package like "vulkan-utils" or "vulkan-info" or something like that. Other than that you need a vulkan loader, according to google that would be "libvulkan1" on ubuntu but may be called differently on other distributions. ![]() a package "mesa-vulkan-drivers" on ubuntu. But it may be packaged separately depending on distribution, e.g. With SteamVR Valve targets the radv vulkan driver that is part of mesa. It works on Linux and enables the use of the OSVR HDK in SteamVR, So if you can get one for cheap, it's a decent-ish alternative, though the positional tracking volume is relatively small and some users report tracking issues after running it a while, mostly attributed to issues with the camera firmware, which sadly is not open source and most likely will never get a fix.ĭon't. SteamVR-OSVR is a SteamVR plugin like SteamVR-OpenHMD, just for OSVR. Basically nobody created linux software for OSVR's SDK though - the OSVR Unity and Unreal plugins don't work on Linux, and pretty much nobody bothered with the C/C++ API. With osvr-core you get positional tracking for the OSVR HDK. Re OSVR: At this point I would not recommend buying the OSVR HDK, though at the currently reduced price of $199.99 it might be an okay-ish price. Nolo controllers can also be activated with the config file but the controller implementation isn't finished in SteamVR-OpenHMD, gotta get buttons done and use a more sensible controller model. The config file for that is pretty rudimentary, but it should do the job. If you have the Nolo HMD tracker attached to the HMD, the SteamVR-OpenHMD plugin can completely replace the HMD's tracker with another tracker like the Nolo tracker, which also gives you positional tracking. There's also a possibility it has something to do with psvr firmware updates, so connecting it to a playstation 4 *may* improve how the firmware reports IMU values, though no guarantees, just a possibility. I heard that the psvr code should be pretty solid in OpenHMD, but make sure to use the most up to date OpenHMD code (in subprojects/openhmd, git pull origin master or something like that). SteamVR already provides a script that should sets LD_LIBRARY_PATH: ~/.local/share/Steam/steamapps/common/SteamVR/bin/vrstartup.sh But if none of these contain the directory where the executable is, then it will not look there for libraries. Then in the environment variable LD_LIBRARY_PATH, etc. Then In the so called "rpath" that is stored in the executable itself. The usual ld loader has a few rules where to look for libraries like: In the paths configured in /etc/ld.so.conf or /etc/ld.so.conf.d/*.conf. Unfortunately the UI is not very intuitive, when pressing a button or making some analog input it shows this in the UI, but then you have to choose the function to assign from a long list of names and hope to assign the right function.ītw: Linux (usually) doesn't do the loading of libraries in the same directory as the executable. You have to go to the joystick settings and set them up separately for each hand. For me the Vive controller bindings were missing completely too. ![]() Preset 5 playback modes to play DVDs on devices as you like.Show video thumbnails and preview video before burning.Create own DVD menu templates by specifying image, music, button or text.Customize DVD with themed menu templates.Retouch videos with a set of editing tools: trim, crop, rotate, add watermark, apply effects, add subtitles, create chapter, adjust volume, audio fade in or out.Burn videos to DVD Folder, ISO File and DVD Disc.Support standard videos, HD videos, downloaded and recorded videos in any format.Also it includes a decent selection of DVD menu templates, you can choose from the themed templates or personalize with background image, music, button, text.

I started reading up on Mama Cass after hearing one of her songs during a yoga class. Do earworms drown out healthy skepticism? What are we not hearing when we opt to party in the U.S.A.? But as hipster adults are increasingly embracing top 40 fodder, I wonder what lies beneath some of these infectious melodies. Certain music is intentionally shallow, marketed toward those who will eventually grow out of it. Genre labels are becoming increasingly meaningless, but the spirit of bubblegum has stuck around, (see: K-POP). In the last decade or so, we’ve made great strides in not discounting songs on account of their catchiness. To be clear: I am a card-carrying poptimist (the card in question being a physical copy of Carly Rae Jepson’s E*MO*TION). ![]() Knowing this might eclipse some of the sunny tone of Bubblegum. “I would say the world’s in terrible shape,” she once quipped, “But I’m afraid the world would say, ‘Look who’s talking.’”īut despite her confident facade, the constant jabs about her body (most viciously from Papa John Phillips) stung deeply. She constantly spat one-liners about her weight in press interviews, late night guest spots, and even song lyrics. Michelle Phillips, the other Mama, might have been a Betty, but Cass was no Veronica. The defining hit of the genre, The Archies’ “ Sugar, Sugar,” was sung by literal cartoon characters. Looks are a key ingredient in the bubblegum industrial complex: you’ve got to have a pretty wrapper. Her vocal artistry is exceptional, but something else sets Cass apart from the bubblegum wads of her time (and now): her body. Lemonade, and Something for Mama! are sugary, effervescent, and lacking in nutrients. It’s a song you play over and over until it loses flavor meant to be tasted but never swallowed. But I think the term evokes more about the way the music is consumed than who is consuming it. Two record execs spun out a new genre named for its targeted audience: boomer teens who spent their untaxed allowances on candy and 45s. The phrase “bubblegum pop” was only a few years old at that point. The chorus is not subtle: Better everyday! repeatedly maniacally, as if she’s convincing herself. The title of her lead single? “ Getting Better.” Lemonade, and Something for Mama!, a brazen PR patch to restore the California dreams of her early days with the Mamas and the Papas. ![]() Months later, she released her second solo album, Bubblegum. In a scathing pan, Newsweek compared Cass to a giant ocean liner, under the headline: “Sink Along with Cass.” She later attributed her botched performance to heroin and nerves, but the prior months of fasting four days a week couldn’t have helped. The next day, Cass was back in LA, hospitalized for tonsillitis, and the rest of the Vegas shows were cancelled. ![]() Then she forgot the name of the next song.”īefore slurring into her finale, “ Dream of Little Dream of Me,” Cass attempted to assure the dwindling crowd: “This is the first night. Flatly and uncertainly, she began her set with “Dancing in the Street,’ Rubber Band,’ and ‘Walk on By,’ assisted by a girl trio. Her hairdo was awry and she showed the effects of having just been awakened by a fifteen-hour sleep. ![]() Rolling Stone reported: “The reception was lukewarm when Cass walked onto the stage in her psychedelic muu-muu. The 1968 concert is a legendary disappointment, with its own section on Cass’s Wikipedia page and a devoted chapter in a 2005 biography. The unlikely breakout of the Mamas and the Papas took the stage on her own on opening night, with a high fever and a shot voice.īy all accounts, she crashed and burned. Caesar’s Palace had paid Cass Elliot a record-breaking fee to re-introduce herself as a solo artist, headlining two shows a night for three weeks. So was Sammy Davis Jr., Joan Baez, Liza Minnelli, and Mia Farrow, who sent flowers to the dressing room. ![]() If you're searching for anime poses full body reference male drawing base topic.

Use "width": "px" to have a specific pixel width.If you have three columns with their width property set to 1, 4 and 5 respectively, they will end up using 10%, 40% and 50% of the available width, respectively. Use "width": for a Column to use a proportion of the available width in the ColumnSet.When multiple Columns have "width": "stretch", they all equally share the remaining width. Use "width": "stretch" for a Column to use the remaining width in the ColumnSet.Use "width": "auto" for a Column to use as much width as is necessary to fit its content.Do use the appropriate sizing approach for columns:.Do use ColumnSet if you need to, for example, display an image of the far left of the card and some text on the same line at the far right of the card.Do use ColumnSet for table-like layouts in general.The Container element makes it possible to group a set of elements together. Use the Container element only when necessary. Such paddings usually interfere with the overall layout by introducing undesirable spacing on the side of your image. Don't craft your images with built-in paddings.For that reason, do make the background of your images transparent. In Outlook, your Adaptive Cards will not necessarily be displayed on top of a white background, and your images should be able to superimpose themselves on top of any background color. Don't design your images with a fixed background color, like white, unless that background color is supposed to be visible to the user.Do use the width and height properties of the Image element if you need to precisely control the actual size of the images in your card.In other words, it is better to design a 100x100 pixels image and display it at 50x50 pixels than to design a 50x50 pixels image and display it at 100x100 pixels. An image designed for a high DPI screen will be shrunk on a lower DPI screen which usually yields good results. An image designed for a low (96) DPI screen will be blown up when displayed on a higher DPI screen and will therefore look pixelated. ![]()

Given you have some more free time and you learn how to fly and land a plane you will definitely have fun with it. It is simply too realistic and too beautiful. In every other aspect the game excels and we are sure you will like it. “Weak” is not the right word too, it’s just how Extreme Landings is and you will have to deal with it. Perhaps toughness is the only weak point in the game as you will have to put some effort into it in order to play it successfully. We never landed a plane successfully and instead of that we had some horrific plane crashes. To be honest with you, Extreme Landings is a tough game. In simple words this means you cannot fall into an abyss, which is something not true for Extreme Landings. This is very tricky as most games on Google Play take place in 2D planes, even though they may be in 3D. To control the plane you must tilt your device and then more – have 3D thinking to know where and how your plane is situated. This is the moment when you will realize that landing the plane is much more difficult than it seems. The plot behind the game is simple – you are given a plane and you must land it at an airport near you. The game also presents you with a number of planes to choose from and this is also a plus the plane you are flying is also very well detailed. Earth beneath has been made very detailed, which adds to the value of the game and you will often see beautiful pictures created by nature such as sunsets and sunrises. The size pays off, though – Extreme Landings is a nice game and you will have fun with it.Įxtreme Landings will treat your eyes with beautiful and colorful 3D graphics that really make you feel like you are flying a plane. Before we go into details we will say that the application is large at around 80 MB so make sure to have a stable and free connection to the Internet before you download it. In Extreme Landings this is exactly what you have to do – land a plane. Although flying by itself seems hard you will soon discover that landing a plane is much, much harder, especially after you play a game for Android, called Extreme Landings. Well, nowadays this is really easy thanks to a fundamental discovery and this is the plane. ![]() Flying has always fascinated people around the world and this is why they have always wanted to find ways to do it. To allow organizations to freely assign private IP addresses, the NIC has reserved certain address blocks for private use. ![]() For example, a network printer may be assigned a private IP address to prevent rest of the world from printing from it. The devices that do not require public access may be assigned a private IP address and make it uniquely identifiable within one organization. In order to maintain uniqueness within global namespace, the IP addresses are publicly registered with the Network Information Center (NIC) to avoid address conflicts.The dDevices that need to be publicly identified, such as web or mail servers, must have a globally unique IP address and they are assigned a public IP address. (2) Class D (224-247, Multicast) and Class E (248-255, Experimental) are not intended to be used in public operation. Note: (1) 127 Network Address reserved for loopback test. With scarcity of IP addresses, the class-based system has been replaced by Classless Inter- Domain Routing (CIDR) to more efficiently allocate IP addresses. The computers identify the class by first 3 bits (A=000, B=100, C=110), while humans identify the class by first octet(8-bit) number. Traditionally IP network is classified as A, B or C network. The host address can further divided into subnetwork and host number. The network address determines how many of the 32 bits are used for the network address and the remaining bits are used for the host address. An example of IPv4 address is 216.3.128.12, which is the IP address previously assigned to .Īn IPv4 address is divided into two parts: network and host address. An IP address is written in "dotted decimal" notation, which is 4 sets of numbers separated by period each set representing 8-bit number ranging from (0-255). A new version of the IP protocol (IPv6) has been invented to offer virtually limitless number of unique addresses. A 32-bit number is capable of providing roughly 4 billion unique numbers, and hence IPv4 addresses running out as more devices are connected to the IP network. The traditional IP Address (known as IPv4) uses a 32-bit number to represent an IP address, and it defines both network and host address. An IP address is analogous to a street address or telephone number in that it is used to uniquely identify an entity. Any device connected to the IP network must have a unique IP address within the network. Additionally, we recommend installing a plug-in that prevents IP address leaks via WebRTC: «Disable WebRTC» or «WebRTC Leak Prevent».The Internet Protocol Address (or IP Address) is a unique address that computing devices such as personal computers, tablets, and smartphones use to identify itself and communicate with other devices in the IP network. For example, using the "Random User-Agent" plugin. Therefore, you can only change it in the browser. ![]() This information is provided by your browser. Is it possible to hide information about the system and the browser? It's better to connect to a VPN service with static addresses. But not everyone provides this opportunity. You can buy a personal IP address service from your internet provider for an additional fee per month. How do I get a permanent address if my IP address is constantly changing? In this case, in addition to changing your IP address, you will protect your internet traffic. The second, even more reliable way is to connect a VPN. Use a Socks proxy with an increased level of anonymity to completely hide the fact that a proxy is being used. How does the service determine that a proxy is being used? ![]() Use a different type of proxy with a higher level of anonymity, or a VPN service. You may have connected the proxy server incorrectly in your browser, or you may be using an HTTP proxy that is not configured to hide your real IP. Why isn't the proxy hiding my real IP address? If you want to not only change the address, but also make it anonymous, you need to use a proxy or VPN. But this will still be your real IP address. Most likely, the network will give you a new address. dynamic IP addresses, it is enough to turn off the router, wait a few minutes, and then turn it on again. If your provider works with changing, i.e. For example, your information is displayed on this page. They ask your browser and system for information about your IP address. You can find out your computer's IP address using specialized services. Here are answers to some of the most popular questions about IP addresses, their use, and ways to change them. This is the unique number of the device connected to the internet or local network. IP address is short for "Internet Protocol Address". Make your topics as short and concise as possible. Keep the MQTT topic short and conciseĮach topic is included in every message in which it is used. UTF-8 has many different white space types, such uncommon characters should be avoided. As with leading forward slashes, just because something is allowed, doesn’t mean it should be used. ![]() When things are not going the way they should, spaces make it much harder to read and debug topics. Never use spaces in a topicĪ space is the natural enemy of every programmer. The zero does not provide any benefit and often leads to confusion. However, the leading forward slash introduces an unnecessary topic level with a zero character at the front. For example, /myhome/groundfloor/livingroom. Use the comments to start a conversation, Let us know your best practices or if you disagree with one of ours! MQTT Best practices Never use a leading forward slashĪ leading forward slash is permitted in MQTT. We have collected the best practices that we have learned from working extensively with MQTT in various projects and are always open to suggestions or a discussion about these practices. When you use wildcards in real-world applications, there are some challenges you should be aware of. As you can see, MQTT topics are dynamic and provide great flexibility. These are the basics of MQTT message topics. $SYS/broker/uptime Summary of MQTT Topics One suggestion for $SYS-topics is in the MQTT GitHub wiki. Commonly, $SYS/ is used for all the following information, but broker implementations varies. At the moment, there is no official standardization for such topics. Clients cannot publish messages to these topics. The $-symbol topics are reserved for internal statistics of the MQTT broker. These topics are not part of the subscription when you subscribe to the multi-level wildcard as a topic (#). However, there is one exception: Topics that start with a $ symbol have a different purpose. Generally, you can name your MQTT topics as you wish. If you expect high throughput, subscription with a multi-level wildcard alone is an anti-pattern (see the best practices below). If you specify only the multi-level wildcard as a topic ( #), you receive all messages that are sent to the MQTT broker. When a client subscribes to a topic with a multi-level wildcard, it receives all messages of a topic that begins with the pattern before the wildcard character, no matter how long or deep the topic is. ![]() For the broker to determine which topics match, the multi-level wildcard must be placed as the last character in the topic and preceded by a forward slash. The hash symbol represents the multi-level wild card in the topic. The multi-level wildcard covers many topic levels. For example a subscription to myhome/groundfloor/+/temperature can produce the following results: The plus symbol represents a single-level wildcard in a topic.Īny topic matches a topic with single-level wildcard if it contains an arbitrary string instead of the wildcard. Single Level: +Īs the name suggests, a single-level wildcard replaces one topic level. There are two different kinds of wildcards: single-level and multi-level. A wildcard can only be used to subscribe to topics, not to publish a message. When a client subscribes to a topic, it can subscribe to the exact topic of a published message or it can use wildcards to subscribe to multiple topics simultaneously. Additionally, the forward slash alone is a valid topic. For example, myhome/temperature and MyHome/Temperature are two different topics. Note that each topic must contain at least 1 character and that the topic string permits empty spaces. USA/California/San Francisco/Silicon Valleyĥff4a2ce-e485-40f4-826c-b1a5d81be9b6/status Myhome/groundfloor/livingroom/temperature ![]() The broker accepts each valid topic without any prior initialization. The client does not need to create the desired topic before they publish or subscribe to it. In comparison to a message queue, MQTT topics are very lightweight. Each topic level is separated by a forward slash (topic level separator). The topic consists of one or more topic levels. In MQTT, the word topic refers to an UTF-8 string that the broker uses to filter messages for each connected client. 72 pages of MQTT education and learning for beginners and experts alike. |
