You can supplement this by using the CPATH variable, or CFLAGS or any number of other environment variables really (conveniently complicated). There is a default path that the linker searches for libraries. Except the env variable is DYLD_LIBRARY_PATH instead. On Mac it is the same for most open source software almost always (unless it is an Xcode Project). On Linux they need to be installed to a path that the dynamic linker can find, this is defined by the LD_LIBRARY_PATH environment variable and the contents of /etc/ld.conf. configure & make finds them, what actually happens when they are linked against How shared libraries work under OS X / Linux - where they live on the filesystem, how.

I apologise for directly answering everything, but I don't know any useful tutorials, FAQs, etc. I'm willing to invest quite a bit of time and effort here - I don't necessarily want direct answers to the above questions, I'd much rather get recommendations on books / tutorials / FAQs that I can read which will give me the knowledge I need to understand what's actually going on and hence figure out problems on my own. What are the command line tools I need to master to get good at this stuff? Stuff like otool, pkg-config etc.Assuming I manage to compile something fiddly from source, how can I then package that up so other people don't have to jump through the same hoops?

![]() ![]() Using these attributes allows the user to resize the widget to a size that may be smaller than the default widget size. These values should specify the size under which the widget would be illegible or otherwise unusable. Specifies the widget's absolute minimum size. If supported, the targetCellWidth and targetCellHeight attributes take precedence over the minWidth and minHeight attributes. Note: We recommend specifying both the targetCellWidth/ targetCellHeight and minWidth/ minHeight sets of attributes, so that your app can fall back to using minWidth and minHeight if the user's device doesn’t support targetCellWidth and targetCellHeight. If the values for a widget's minimum width or height don't match the dimensions of the cells, then the values are rounded up to the nearest cell size. The minWidth and minHeight attributes specify the default size of the widget in dp.These attributes will be ignored in Android 11 and lower, and may be ignored if the home screen doesn’t support a grid-based layout.

Tip: For an authentic restaurant-style sizzling fajita presentation, heat the cast-iron fajita skillets in a hot oven while preparing the chicken and vegetables. Serve immediately with your choice of the following on the side: peppers, onion, sliced avocado, lime wedges and fresh cilantro. To serve, cut the chicken breasts into thin slices, and divide among cast-iron fajita platters if using (see tip below) or individual serving plates. Add the sliced peppers and onion, and cook, stirring frequently, until crisp-tender and nicely browned, 6 to 7 minutes. Increase heat to medium-high, and add remaining olive oil to skillet. The heat will continue to rise another 5 degrees while the meat rests.

Polenta, Sausage and Portobello CasseroleĬombine milk, butter and salt in a heavy saucepan, and heat to a simmer. Compared to dent corn, which is used to make grits, flint corn has less starch, meaning that polenta is not as creamy and velvety as grits (but decadent nonetheless)." The kernels used for polenta come from flint corn, which is a hearty variety of corn originally found in Italy. Polenta is similar to Southern grits in both taste and preparation, but there is one key difference. "Polenta is made of stone-ground dried yellow corn kernels that have a flaky texture. If you are accustomed to seeing polenta in refrigerated logs, here is some guidance from Real Simple magazine that separates the grits from the polenta. This autumnal treasure came from a cookbook, "Mary James Dishes It Out," shared with this column by T.R.B. Today we are opening a new chapter of Best of the Best: What is the best thing you have prepared in your kitchen, or sampled in another dining room? As winter is fast approaching and we will need the comfort of food, we would welcome your submissions for appetizer, drink, entrée, side and dessert. Could you please tell her your secret and a recipe or two as well? In our conversation over said dinner table, she also asked for a recipe for white lasagna, "hoping it is easier to make than the traditional version." Today we have an impassioned plea at an anonymous dinner table, where the cook simply cannot make tender chicken on the stovetop. ![]() ![]() An open set and closed set are being kept. PathPlanner class is defined to get a map, a start node and destination node and method is defined to compute the shortest path between those two while searching in the right direction. The A* algorithm is implemented in project_notebook.ipynb using starter code provided by Udacity. Test.py is provided by Udacity to test the results of the implementation given the provided two maps. The information about the map is kept in the dictionary as keys for nodes ids and values for the city's latitude and longitude as well as the adjacent cities. A map is created through the class Map who builds a graph (as a network) from values given in a dictionary. The files are:įrom helpers.py two maps are imported. This project is implemented in Python under Jupyter Notebook. This requirement is fulfilled when the heuristic is the straight distance between two points on a map since real roads paths are generally longer. For A* to find the shortest path, the heuristic of each node needs to be optimistic, or to represent an estimation that is shorter or equal than the real distance. The distance estimation is called the heuristic. A* is expanding the route that keeps the sum of total cost and the distance Since it does not keep record of the lowest total cost, it will find the destination but it will not always provide the shortest route, for example if there are obstacles along the way.įinding the shortest path while searching in the correct direction is where A* is the best choice. For the map search this is the straight line between nodes A and B.īest First Search, or greedy algorithm, always searches for the next node which gets you closest to the destination based on the estimate of the distance. For this we calculate the estimate distance between the start point and the destination. We want a targeted search that gets us in the direction of the destination. ![]() Imagine looking for your destination while going in the opposite direction. The bigger the map, the more obvious the inefficiency is. This algorithm works well if there is no concern for efficiency and number of operations. If all roads would be equal in cost, this search method is basicly the Breadth First Search When the destination is found and picked as being the shortest path from the start, we know that we found the shortest route. The nodes are explored in order based on how far they are from the start and keeping track of the total cost. ![]() The Uniform Cost Search is guaranteed to find the cheapest path from a starting node to the destination.īest Cost Search algorithm based on Dijkstra's algorithm applies the cheapest first method, expanding the shortest route from the start in every direction. Finding the shortest path is reduced to minimizing the total cost of the path. Operating on a real time system as in an autonomous vehicle, the efficiency of the algorithm is a big concern.ĭistances between cities can be seen as cost. The second is how the shortest route can be computed. The first is minimizing the total distance or cost of the final route. The best algorithm for this graph search needs to take into account two factors. Now that the problem has been reduced to a graph representation, the task is limited to a graph search that is best suited for this case. The car's current location is node A and the destination city is node B. Together with a list of its neighboring cities. For each city the global position is considered known, in terms of latitude and longitude, Cities are seen as nodes and roads are its edges. Given that the map is known, this can be represented under the form of a graph. Google maps style routing algorithm to calculate the shortest path between two points using A* search algorithm.įinding the shortest path between two locations is a key task in path planning expecially for self driving cars to navigate from point A to point B. ![]() |
