There is a certain chance that you might know some of them because of their notable use, but still, there are many you might want to know. In that case, you might want to know the VLC keyboard shortcuts and how to change the VLC keyboard shortcuts for a better experience and time management.Ī detailed guide to VLC keyboard shortcuts and keyboard shortcuts subtitles have been provided below, along with the VLC shortcuts pdf to help you learn as many shortcuts as possible. So, suppose you watch videos regularly either for educational purposes or entertainment purposes or whatever reason. Thus, the working range of the VLC player justifies the popularity of the player along with its frequent use.Ĭonsidering the frequent use of the VLC player, certain short keys, also known as hotkeys, are introduced to save the precious time of its users. Moreover, it is a free and open-source player that supports all the desktop operating systems and mobile platforms, including VLC keyboard shortcuts for Mac. Thus, in the example above, a snapshot with sequential numbering would look like this: Friends-00_05_21-000001.pngįor a full list of variables, please see Documentation:Play HowTo/Format String.The VLC media player is a software player that efficiently supports almost all multimedia files and various streaming platforms. Instead of numbers like -14h57m19s163, VLC will simply insert the count of snapshots for that session-for example, 00004. This indicates a snapshot taken at 5 minutes and 21 seconds into the video and it was taken on this day at this time: -14h57m19s163.įor a shorter file name, check the "Sequential numbering" option in the configuration box (below). If you were to change the prefix to Friends-$T- while watching a DVD of Friends, then the snapshot filenames would look something like this: Friends-00_05_21-14h57m19s163.png. For example, $T (must be upper case) will insert the video's time code into the file name. ![]() Also, the default name for snapshots is vlcsnap- followed by a timestamp that is not the time of the frame in the video you're viewing, but rather the current date and time-as in -14h57m19s163.Īlso, you may substitute other text for vlcsnap- in the Video snapshot file prefix and you may choose to have snapshots numbered sequentially (i.e., 000001, 000002, 000003, and so on) instead of with a timestamp.Īs of version 0.9.0, you may even use variables in the text used for the filename. The default format for snapshots is PNG, but this may be changed to JPEG. The location, format and name of snapshots may be changed in the Preferences menu item in the Tools tab, subsection Video.

![]() Listening to our hearts is crucial to living a fulfilling life. Along the way, he meets a variety of people who help him on his journey, including an alchemist who teaches him to listen to his heart. In The Alchemist, Santiago is a shepherd boy who embarks on a journey to fulfill his personal legend. “The secret of life, though, is to fall seven times and to get up eight times.” – Paulo Coelho, The Alchemist The Importance of Listening to Your Heart When we follow our personal legend, we are living in alignment with our true selves, and we are fulfilling our purpose in this life. The Alchemist reminds us that our personal legend is not just a dream, but it is a calling from our souls. We often convince ourselves that our dreams are impossible to achieve before we even try. The mysterious force that Coelho speaks of is the fear of failure. But, as time passes, a mysterious force begins to convince them that it will be impossible for them to realize their Personal Legend.” They are not afraid to dream, and to yearn for everything they would like to see happen to them in their lives. “At that point in their lives, everything is clear and everything is possible. “Everyone, when they are young, knows what their Personal Legend is,” Paulo Coelho writes. The Alchemist teaches us that we all have a personal legend, and it is up to us to follow it. It is the path that leads us to our true purpose and our true selves. Our personal legend is the journey that we are meant to take in this life. “There is only one thing that makes a dream impossible to achieve: the fear of failure.” – Paulo Coelho, The Alchemist The Alchemist encourages us to face our fears head-on and to trust that the universe will support us on our journey. “If you do, you won’t be able to talk to your heart.” Fear is a natural response to the unknown, but it can also hold us back from living the life we want. “Don’t give in to your fears,” Paulo Coelho writes. When we pursue our dreams, we are living our purpose, and we are living in alignment with our true selves. They are the things that make us feel alive, and they are the things that give our lives meaning. The Alchemist teaches us that our dreams are not just idle fantasies, but they are a calling from our souls. ![]() The resistance of concrete to freezing and thawing in a moist condition is significantly improved by the use of intentionally entrained air. Local weather records can help determine the severity of exposure. Note comparison with common pin.Īir entrainment - The severity of freeze-thaw exposure varies with different areas of the United States. Small pinpoint size bubbles (entrained air) uniformly distributed through the paste are beneficial air voids. ![]() Also, installation of effective drainage systems for carrying free water out from under the pavement may be helpful.Ĭross section of air-entrained (right) and non-air-entrained concrete. This problem can be reduced either by selecting aggregates that perform better in freeze-thaw cycles or, where marginal aggregates must be used, by reducing the maximum particle size. Then with freezing and thawing cycles, cracking of the concrete starts in the saturated aggregate at the bottom of the slab and progresses upward until it reaches the wearing surface. D-cracking is a function of the core properties of certain types of aggregate particles and the environment in which the pavement is placed.ĭue to the natural accumulation of water under pavements in the base and subbase layers, the aggregate may eventually become saturated. D-cracks are closely spaced crack formations parallel to transverse and longitudinal joints that later multiple outward from the joints toward the center of the pavement panel. ![]() Click here for a case study on conductive concrete used for bridge deck deicing.ĭ-Cracking - Cracking of concrete pavements caused by the freeze-thaw deterioration of the aggregate within concrete is called D-cracking. Table 11-5 of Design and Control of Concrete Mixtures 15th edition, provides excellent guidance on the effective temperatures and includes the effects on the concrete, practical temperature limits, chemical form, and corrosion of metal potentials. Since scaling damage to pavements of all types is caused by physical salt attack, the use of high strength (4,000 psi or more), low permeability, air entrained concrete is crucial to good durability in these applications. The list of deicers used for these applications includes urea, potassium acetate, propylene glycol, and ethylene glycols. The high concentration of deicers reduces the number of freezing and thawing cycle exposures to the pavement by significantly lowering the freezing point.ĭeicers for special applications such as airport pavements require non-chloride materials to prevent damage to aircraft. A recent trend has seen a wide variety of blends of these materials to improve performance while reducing costs, and best practice indicates that a liberal dosage greater than four percent in solution tends to decrease the potential for scaling of pavement surfaces. These chemicals reduce the freezing point of the precipitation as it falls on pavements. ![]() The accumulative effect of successive freeze-thaw cycles and disruption of paste and aggregate can eventually cause expansion and cracking, scaling, and crumbling of the concrete.ĭeicing chemicals for pavements include sodium chloride, calcium chloride, magnesium chloride, and potassium chloride. If the pressure developed exceeds the tensile strength of the concrete, the cavity will dilate and rupture. As the water in moist concrete freezes it produces pressure in the pores of the concrete. When water freezes, it expands about 9 percent. ![]() ![]() Via Dragging: Via dragging is a special case since you don't often move by a large amount and any direction will often do.The goal of all editing is to maintain 90 and 45 degree segments as this both enables future segment drag editing and software tidy operations. Linear Route Editing: Various improvements to segment dragging, node dragging and small segment removal.Curved corners can be dragged to enlarge or contract their radius and straight segments between curves can be dragged exactly like linear segment dragging. ![]() Curved Route Editing: The editing of curved routes has been overhauled to work in a similar way to linear routes.Note that this version involves a file format change which is not backwards compatible with older versions of the software. It can be downloaded from the home page of the software. We are pleased to announce that Proteus Design Suite 8.15 has now been released. Proteus 8.16 is available free of charge to all customers whose USC is valid as of 20 th March 2023. Length Matched Tracks Viewer:New matchgroup view directly in the parts bin gives a live board insight on length matched routes and their compliance status with target lengths.įor a full listing of features and fixes please log on to our support forums and look under the 'Updates and Fixes' section.Status Bar Messaging: Status Bar messaging has been upgraded during route placement and editing to include live route lengths, current routing mode and route styles and net information.This instantly lets you see whether the route being placed can move where you want it to go and then take action such as toggling push mode or changing track style to squeeze through a tight gap. Visual DRC: Visual DRC provides a viewport around the mouse and each object shows an expansion corresponding to it's design rule clearance in an overlay.Importantly the keyboard shortcut can launch the dialogue form while in the middle of placing or editing a route meaning that you can make changes or adapt the routing modes at any time. It can be launched from the Tools Menu or, more commonly, via the 'R' keyboard shortcut. Route Command Centre: The Route Command Centre is the home for all route placement, editing and Visual DRC configuration options in Proteus.This can be disabled via keyboard shortcut or through the Route Command Centre. DRC Aware Route Editing: Track editing operations are now by default all design rule aware, allowing you easily make the most of the available board space and keep a tidy board layout.Keyboard shortcuts enable you to seamlessly switch between modes at any time. The former allows the route being placed to move other tracks (and optionally vias) out of the way while the latter is more akin to a hug mode which will obey design rule clearances but will not affect other objects on the PCB. Push and Shove Routing: There are now two main placement mods, namely Push mode and traditional FMR mode.We are pleased to announce that Proteus Design Suite 8.16 has now been released. |
